[ "Impact of enhanced pharmacologic care on the prevention of falls: a randomized controlled trial." ]

[ "Falls are the leading cause of both fatal and nonfatal injuries among older adults in the United States. Medications that affect the central nervous system are known to increase the risk of falling.\n The purpose of this study was to assess the effects of a community pharmacy-based falls-prevention program targeting high-risk older adults on the rates of recurrent falls, injurious falls, and filling prescriptions for medications that have been associated with an increased risk of falling.\n This was a randomized controlled trial of participants recruited through a community pharmacy chain in North Carolina. The 2-year study consisted of a 1-year \"look-back\" period before randomization and a 1-year follow-up period after randomization. Patients were eligible to participate if they were ≥65 years of age, had fallen at least once during the 1-year period preceding enrollment, and were taking medications associated with an increased risk of falling. Medications classified as high risk included benzodiazepines, antidepressants, anticonvulsants, sedative hypnotics, opioid analgesics, antipsychotics, and skeletal muscle relaxants. Participants were assigned to either the intervention arm or the control arm; participants in the intervention arm were invited to attend a face-to-face medication consultation conducted by a community pharmacy resident, whereas those in the control arm received no medication consultation. The primary end point was the rate of recurrent falls during the 1-year followup period. Secondary end points were the total number of prescriptions for high-risk medications filled during the follow-up period and either discontinued use or a reduction in the dosage of a high-risk medication during the follow-up period.\n One hundred eighty-six patients (132 women, 54 men; 88.7% white) were enrolled. Intention-to-treat (ITT) analyses revealed no significant differences in the rates of recurrent falls, injurious falls, or filling prescriptions for high-risk medications. However, 13 patients in the intervention group either discontinued use of a high-risk medication or had the dosage reduced during the follow-up period, compared with 5 patients in the control group (χ(2) = 3.94; P < 0.05). As-treated analyses revealed numeric reductions in the rates of falls (rate ratio [RR] = 0.76; 95% CI, 0.53-1.09), injurious falls (RR= 0.67; 95% CI, 0.43-1.05), and filling prescriptions for high-risk medications (RR= 0.85; 95% CI, 0.72-1.03) after receipt of the intervention, but the differences were not statistically significant.\n Results of this study support the feasibility of using community pharmacies to deliver a falls-prevention program targeting high-risk older adults. Although the ITT analyses revealed no significant reduction in the rate of recurrent falls, injurious falls, or overall use of high-risk medications, individuals in the intervention group were more likely than those in the control group to discontinue use of a high-risk medication or have the dosage reduced during the 1-year follow-up period. More work is needed to evaluate the intervention using a larger sample size that provides greater power to detect clinically meaningful effects of reduction in the use of high-risk medications on preventing or reducing falls in the high-risk population.\n Copyright © 2010 Elsevier HS Journals, Inc.

[ "The clinical efficacy and safety of vigabatrin (VGB) as add-on therapy for pharmaco-resistant focal epilepsies is well established. However, for an objective evaluation, the effects of the drug in the monotherapy of newly diagnosed subjects should be determined. With this aim, VGB was compared, in a randomized, response conditional cross-over study, with carbamazepine (CBZ), the most widely prescribed drug in focal epilepsies. Fifty-one patients with complex partial (CP) seizures were randomly assigned to either the VGB or the CBZ group and evaluated after an initial 4 month period. The cross-over to the alternative drug was carried out, for an analogous period, only in cases with persisting seizures or in the presence of intolerable side effects. Patients who did not respond to either drug were subsequently treated with a combination of VGB and CBZ. No significant difference was revealed in the efficacies of VGB and CBZ; a complete control of seizures was obtained in 17/37 patients (45.9%) treated with VGB and in 20/39 patients (51.3%) treated with CBZ. The side effects were somewhat more frequent (41%) and severe with CBZ than with VGB (21.6%). The power to detect a 20% difference between the two drugs was 75%. The combination of the two drugs suppressed the seizures in 5 out of 14 resistant cases. The preliminary results in this small number of patients are encouraging and suggest that VGB may be considered as a first-line drug for epilepsy with CP seizures and as a valid alternative when other monotherapies are ineffective or poorly tolerated.", "Carbamazepine (CBZ) is a drug of choice for the treatment of simple or complex partial seizures and secondary generalized seizures in adults and children. Vigabatrin (VGB) is a relatively new second line antiepileptic drug and was first registered for use in Poland more than ten years ago. Few reports have been published on the comparison of efficacy of VGB in children with epilepsy. The objective of this study is to evaluate the safety, efficacy and EEG effects of initial VGB monotherapy compared with initial CBZ monotherapy in children with newly diagnosed epilepsy. We present results of a prospective, outpatient and open study carried out in the University Hospital Center in Białystok. Twenty-six children with partial epilepsy treated with VGB and 28 patients treated with CBZ were studied. The evaluation of the efficacy of the two drugs did not reveal any significant differences. Very good (reduction > 75%) seizure control was achieved in 22 out of 26 patients (84.6%) in the VGB group. One patient had a 50-75% decrease of seizures (good effect), similarly one child had a 25-50% reduction of seizures (mild effect). In two patients, we observed increased seizures (myoclonic jerks). Very good seizure control was achieved in 17 out of 28 patients (60.7%) in the CBZ group. Good seizure control was achieved in 5 out of 28 patients (17.8%) and mild control was seen in two children. No improvement was observed in 4 (14%) of the patients. The EEG background activity was improved in VGB-treated patients. No effect on the EEG background activity was observed in CBZ-treated children. VGB seems to be a safe and effective antiepileptic drug as primary monotherapy for epilepsy in children with similar proportion of side effects as CBZ.", "The efficacy and safety of lamotrigine and carbamazepine as monotherapy in patients with untreated, newly diagnosed or recurrent partial and/or generalised tonic-clonic seizures, were compared in a randomised, open, multicentre study. Patients received 24 weeks' treatment with oral lamotrigine 100 mg (LTG 100, n = 115) or 200 mg (LTG 200, n = 111) or carbamazepine 600 mg (CBZ 600, n = 117). Efficacy measurements were comparable between the three treatment groups, although the higher lamotrigine dose was possibly most effective, with 60.4% completing seizure free compared with 51.3% (LTG 100) and 54.7% (CBZ 600). Both dosage regimens of lamotrigine were well tolerated. More patients on CBZ 600 reported adverse experiences, 66% versus 53% (LTG 100) and 58% (LTG 200), and of these a greater proportion were attributed to CBZ 600 treatment, 53% versus 23% (LTG 100) and 28% (LTG 200). Similarly, a greater proportion of the CBZ 600 group required a change in dose, 47% versus 20% (LTG 100) and 17% (LTG 200) or withdrew completely due to adverse experiences, 10.3% versus 4.3% (LTG 100) and 4.5% (LTG 200). The most common adverse experience leading to withdrawal was rash, with approximately double the proportion of reports occurring in patients on CBZ 600 (5.1%) compared with lamotrigine (1.7% on LTG 100 and 2.7% on LTG 200). Overall lamotrigine appeared equally effective but better tolerated compared with carbamazepine.", "In a multicentre, double-blind trial 150 elderly patients (mean age 77 years) with newly diagnosed epilepsy were randomised in a 2:1 ratio to treatment with lamotrigine (LTG) or carbamazepine (CBZ). Following a short titration period, the dosage was individualised for each patient while maintaining the blind over the next 24 weeks. The main difference between the groups was the rate of drop-out due to adverse events (LTG 18% versus CBZ 42%). This was in part a consequence of the lower rash rate with LTG (LTG 3%, CBZ 19%; 95% CI 7-25%). LTG-treated patients also complained less frequently of somnolence (LTG 12%, CBZ 29%; 95% CI 4-30%). Although there was no difference between the drugs in time to first seizure, a greater percentage of LTG-treated patients remained seizure-free during the last 16 weeks of treatment (LTG 39%, CBZ 21%; P = 0.027). Overall, more patients continued on treatment with LTG than CBZ (LTG 71%, CBZ 42%; P < 0.001) for the duration of the study. The hazard ratio for withdrawal was 2.4 (95% CI 1.4-4.0) indicating that a patient treated with CBZ was more than twice as likely to come off medication than one taking LTG. In conclusion, LTG can be regarded as an acceptable choice as initial treatment for elderly patients with newly diagnosed epilepsy.", "Using a randomized parallel group study design, we compared the cognit ive effects of carbamazepine (CBZ), phenobarbital (PB), and valproate (VPA) in children with epilepsy. Seventy-three children with newly diagnosed epilepsy were tested with the Wechsler Intelligence Scale for Children-Revised (WISC-R), Bender-Gestalt test, and auditory event-related potentials (P 300) before and 6 and 12 months after antiepileptic drug (AED) treatment. There were no significant differences in WISC-R IQs and Bender-Gestalt scores for children in any group at any of the three sessions. P 300 latencies were increased in the children receiving PB but not in children receiving CBZ and VPA. P 300 amplitudes were significantly reduced in treated children in all three groups, but amplitudes were not significantly different among the three groups. These findings suggest that PB may affect cognitive function of epileptic children and that the P 300 may be a sensitive additional procedure that can be used to assess the cognitive effect of AEDs." ]

[ "High rates of hepatitis B virus (HBV) infection and primary liver cancer (PLC) are present in Qidong county. Epidemiological surveys demonstrated an inverse association between selenium (Se) level and regional cancer incidence, as well as HBV infection. Four-year animal studies showed that dietary supplement of Se reduced the HBV infection by 77.2% and liver precancerous lesion by 75.8% of ducks, caused by exposure to natural environmental etiologic factors. An intervention trial was undertaken among the general population of 130,471. Individuals in five townships were involved for observation of the preventive effect of Se. The 8-yr follow-up data showed reduced PLC incidence by 35.1% in selenized table salt supplemented vs the nonsupplemented population. On withdrawal of Se from the treated group, PLC incidence rate began to increase. However, the inhibitory response to HBV was sustained during the 3-yr cessation of treatment. The clinical study among 226 Hepatitis B Surface Antigen (HBsAg)-positive persons provided either 200 micrograms of Se in the form of selenized yeast tablet or an identical placebo of yeast tablet daily for 4 yr showed that 7 of 113 subjects were diagnosed as having PLC in the placebo group, whereas no incidence of PLC was found in 113 subjects supplemented with Se. Again on cessation of treatment, PLC developed at a rate comparable to that in the control group, demonstrating that a continuous intake of Se is essential to sustain the chemopreventive effect.", "The purpose of this study was to evaluate the effect of selenium (Se) in the prevention of human primary liver cancer. Three intervention trials were conducted among the residents at high risk to primary liver cancer (PLC) in Qidong county, Jiang-su province, the People's Republic of China. This area has the second highest rate of PLC in China. One trial was undertaken among the general population in a township with supplement of table salt fortified with 15 ppm anhydrous sodium selenite (Se-salt) for 5 y and the other four townships with similar PLC incidence rate served as the controls using normal table salt. The second trial was undertaken among hepatitis B virus surface antigen carriers (HBVsAg+) receiving supplement of 200 micrograms Se in form of selenized yeast (Se-yeast) daily vs placebo for 4 y. The third trial was carried out in members of families with high PLC incidence using Se-yeast (200 micrograms of Se daily) vs placebo for 2 y. The results showed that nutritional supplement of Se could reduce the PLC incidence significantly.", "The treatment of chronic hepatitis C is relatively unsatisfactory and many patients have turned to unproven alternative medicines to modify the course of their illness. We report a study of a Chinese herbal medicine preparation CH-100 in the management of chronic hepatitis C. Patients with documented chronic hepatitis C were randomly allocated to receive active herbal or placebo tablets (five tablets thrice daily). Patients were followed monthly and evaluated by a Western and a traditional Chinese medical practitioner. Therapy was monitored by measurement of liver function tests, creatinine and full blood count on a monthly basis. Twenty patients in each group were well matched for age, sex, duration of illness, previous interferon therapy and alcohol intake. Active Chinese herbal medication was associated with a significant reduction in alanine aminotransferase (ALT) levels over the 6 month study period (P < 0.03). No patient cleared the virus but four normalized their ALT on treatment. Appropriately prescribed Chinese herbal medicine may have a role in the management of chronic hepatitis C and further controlled studies are indicated.", "Both experimental and epidemiologic studies have linked a low dietary intake of selenium with an increased risk of cancer. The authors examined the association between plasma selenium levels and risk of hepatocellular carcinoma (HCC) among chronic carriers of hepatitis B and/or C virus in a cohort of 7,342 men in Taiwan who were recruited by personal interview and blood draw during 1988-1992. After these men were followed up for an average of 5.3 years, selenium levels in the stored plasma were measured by using hydride atomic absorption spectrometry for 69 incident HCC cases who were positive for hepatitis B surface antigen (HBsAg) and/or antibodies against hepatitis C virus (mostly HBsAg positive) and 139 matched, healthy controls who were HBsAg positive. Mean selenium levels were significantly lower in the HCC cases than in the HBsAg-positive controls (p = 0.01). Adjusted odds ratios of HCC for subjects in increasing quintiles of plasma selenium were 1.00, 0.52, 0.32, 0.19, and 0.62, respectively. The inverse association between plasma selenium levels and HCC was most striking among cigarette smokers and among subjects with low plasma levels of retinol or various carotenoids. There was no clear evidence for an interaction between selenium and alpha-tocopherol in relation to HCC risk.", "The effect of vitamin E administration on clinical and laboratory parameters of liver function and on markers of fibrogenesis was assessed in patients with mild to moderate alcoholic hepatitis in a double blind placebo controlled randomized trial.\n Twenty-five patients received 1000 I.U. of vitamin E per day, while 26 patients received placebo for 3 months. The patients were followed for 1 year after entry into the trial.\n Vitamin E did not result in significant greater decreases in serum aminotransferases and serum bilirubin or in greater increases in serum albumin as compared with placebo. Prothrombin time did not change, while serum creatinine remained in the normal range. Monocyte nuclear nuclear factor-kappa B binding activity decreased in patients who remained abstinent, regardless of whether they received vitamin E. As regards markers of hepatic fibrogenesis, vitamin E treatment decreased serum hyaluronic acid (P<0.05) while serum aminoterminal peptide of type III procollagen did not change in either group. Four patients in the treatment group and five in the placebo group died during the 1-year study.\n Vitamin E treatment improves serum hyaluronic acid but has no beneficial effects on tests of liver function in patients with mild to moderate alcoholic hepatitis.", "Chronic hepatitis C is the most common indication for liver transplantation, but viral recurrence is universal and progressive graft injury occurs in most recipients. Our aim was to assess the safety, pharmacokinetics (PK), and antiviral effects of high doses of a human hepatitis C antibody enriched immune globulin product (HCIG) in patients undergoing liver transplantation for chronic hepatitis C. This was a multicenter, randomized, open-label, controlled trial conducted at 4 transplant centers in the United States. A total of 18 patients with chronic hepatitis C, who underwent liver transplantation, were randomized to receive low-dose HCIG (75 mg/kg) or high-dose HCIG (200 mg/kg), or no treatment. A total of 17 infusions of HCIG were administered in each treated patient over 14 weeks using a time-dependent dosing strategy based on the PK of anti-hepatitis B immune globulin in liver transplant recipients. Hepatitis C virus levels, liver enzymes, and liver biopsies were obtained serially throughout the study period. PK profiles of HCV antibodies were determined on days 4, 10, and 98. HCIG infusions were safe and tolerated. The infusion rate could not be maximized because of symptoms for 18% to 30% of the doses. The half-life of HCIG was extremely short immediately after transplantation but was gradually prolonged. In the high-dose group, serum alanine aminotransferase (ALT) levels normalized in most subjects and no patient developed hepatic fibrosis. However, serum HCV RNA levels were not suppressed at either dose. In conclusion, HCIG, an anti-HCV enriched immune globulin product, appears to be safe in patients with chronic hepatitis C undergoing liver transplantation. Further studies are required to determine whether the drug has beneficial effects in this group of patients.", "Silymarin, the active principle of the milk thistle Silybum marianum, protects experimental animals against various hepatotoxic substances. To determine the effect of silymarin on the outcome of patients with cirrhosis, a double blind, prospective, randomized study was performed in 170 patients with cirrhosis. 87 patients (alcoholic 46, non-alcoholic 41; 61 male, 26 female; Child A, 47; B, 37; C, 3; mean age 57) received 140 mg silymarin three times daily. 83 patients (alcoholic 45, non-alcoholic 38; 62 male, 21 female; Child A, 42; B, 32; C, 9: mean age 58) received a placebo. Non-compliant patients and patients who failed to come to a control were considered as 'drop outs' and were withdrawn from the study. All patients received the same treatment until the last patient entered had finished 2-years of treatment. The mean observation period was 41 months. There were 10 drop outs in the placebo group and 14 in the treatment group. In the placebo group, 37 (+2 drop outs) patients had died, and in 31 of these, death was related to liver disease. In the treatment group, 24 (+4 drop outs) had died, and in 18 of these, death was related to liver disease. The 4-year survival rate was 58 +/- 9% (S.E.) in silymarin-treated patients and 39 +/- 9% in the placebo group (P = 0.036). Analysis of subgroups indicated that treatment was effective in patients with alcoholic cirrhosis (P = 0.01) and in patients initially rated 'Child A' (P = 0.03). No side effects of drug treatment were observed.(ABSTRACT TRUNCATED AT 250 WORDS)", "A randomized double-blind trial of silymarin versus placebo was carried out in 116 patients with histologically proven alcoholic hepatitis, 58 of them with cirrhosis. Patients were not included in case of hepatic encephalopathy, contraindication to percutaneous liver biopsy, hepatocellular carcinoma, evident lack of discipline or refusal to enter the trial. Fifty-seven patients received silymarin orally 420 mg/day and 59 received placebo during 3 months. Biologic parameters were assessed in the serum, and a percutaneous liver biopsy was obtained at the start of the trial and 3 months later. Histologic scores of alcoholic hepatitis and fibrosis were established on each biopsy specimen by two independent pathologists. The 2 groups were comparable at inclusion; 26 p. 100 of patients were lost to follow-up at 3 months, abstinence was obtained in 46 p. 100 of patients at the end of the trial. These percentages were similar in the two groups. Four patients died of hepatic failure during the trial, 3 in the placebo group. Significant improvement in the score of alcoholic hepatitis and serum amino transferase activity, was noted in both groups during the trial, irrespective of treatment with silymarin or placebo. No side-effects were noted. Our results suggest that silymarin 420 mg/d is not clinically relevant in the treatment of moderate alcoholic hepatitis.", "Cytomegalovirus (CMV) disease is a frequent cause of serious morbidity after solid-organ transplantation. The prophylactic regimens used to prevent CMV infection and disease have shown limited benefit in seronegative recipients. We studied the safety and efficacy of oral ganciclovir in the prevention of CMV disease following orthotopic liver transplantation.\n Between December, 1993, and April, 1995, 304 liver-transplant recipients were randomised to receive oral ganciclovir 1000 mg or matching placebo three times a day. Seronegative recipients of seronegative livers were excluded. Study drug was administered as soon as the patient was able to take medication by mouth (no later than day 10) until the 98th day after transplantation. Patients were assessed at specified times throughout the first 6 months after surgery for evidence of CMV infection, CMV disease, rejection, opportunistic infections, and possible drug toxicity.\n The Kaplan-Meier estimate of the 6-month incidence of CMV disease was 29 (18.9%) of 154 in the placebo group, compared with seven (4.8%) of 150 in the ganciclovir group (p < 0.001). In the high-risk group of seronegative recipients (R-) of seropositive livers (D+), incidence of CMV disease was 11 (44.0%) of 25 in the placebo group, three (14.8%) of 21 in the ganciclovir group (p = 0.02). Significant benefit was also observed in those receiving antibodies to lymphocytes, where the incidence of CMV disease was 12 (32.9%) of 37 in the placebo group and two (4.6%) of 44 in the ganciclovir group (p = 0.002). Oral ganciclovir reduced the incidence of CMV infection (placebo 79 [51.5%] of 154; ganciclovir 37 [24.5%] of 150; p < 0.001) and also reduced symptomatic herpes-simplex infections (Kaplan-Meier estimates: placebo 36 [23.5%] of 154; ganciclovir five [3.5%] of 150; p < 0.001).\n Oral ganciclovir is a safe and effective method for the prevention of CMV disease after orthotopic liver transplantation.", "A randomized double-blind trial of colchicine vs placebo was conducted in 67 patients with histologically proven alcoholic hepatitis, 33 of whom had cirrhosis. Patients with hepatic encephalopathy, ascites, protracted prothrombin time, severe thrombocytopenia, hepatocellular carcinoma, evident lack of discipline or refusal to participate in the trial were not included. Thirty-three patients received colchicine (1 mg/day) and 34 received placebo for 6 months. Blood parameters including N-terminal peptide of type III procollagen were assessed in the serum, and a percutaneous liver biopsy was performed at the start of the trial and after 3 and 6 months. Alcoholic hepatitis and fibrosis scores were established for each biopsy specimen. Twenty-eight percent of patients were lost to follow-up at 3 months, and fifty-two percent at 6 months. One patient died of liver failure. Fifty-eight percent of patients were abstaining from alcohol at 3 months and fifty percent at 6 months. No significant effect of treatment was noted. Nevertheless, improvement in alcoholic hepatitis core at 3 months was more important in the colchicine group than in the placebo group. No side-effects were noted except transient diarrhea. Our results suggest that colchicine has no important effect on the course of alcoholic hepatitis. A trial including of at least 260 patients might be necessary for the observed alcoholic hepatitis score difference at 3 months, favoring colchicine, to be statistically significant.", "The use of postdetection antiviral treatment of cytomegalovirus (CMV) as a strategy to prevent infection and disease in solid-organ transplant patients has not been evaluated by placebo-controlled trials. We carried out such a study in 69 patients who had received liver transplants and had positive results of CMV polymerase chain reaction within 8 weeks after transplantation but did not have concomitant CMV infection or disease. These patients were randomly assigned to receive placebo or oral ganciclovir for 8 weeks. CMV infection developed in 21% and disease developed in 12% of placebo recipients (P =.022), compared with 3% and 0%, respectively, among ganciclovir recipients (P =.003). Similarly, in the placebo arm, 55% and 36% of CMV-negative patients who received organs from CMV-positive donors developed CMV infection or disease, respectively (P =.02), compared with 11% and 0% of such patients in the ganciclovir arm (P <.01). Oral ganciclovir administered on CMV detection by PCR prevents CMV infection or disease after liver transplantation.", "In previously published studies ursodeoxycholic acid (UDCA) showed beneficial effect on the course of chronic hepatitis. We investigated the effect of UDCA on the course of acute viral hepatitis in a prospective double-blind study. Seventy-eight consecutive patients were randomly assigned either to the UDCA group or to placebo. At 12 months of follow-up 76 patients were available for the final assessment. The analysis of all cases and of the patients with hepatitis B (n = 59) showed a comparable rate of decline of the alanine aminotransferase and other liver function tests in the treatment group and in the placebo group. However, the elevation of alanine aminotransferase persisted more frequently in the placebo group (all cases, p = 0.05; hepatitis B group, p = 0.03). Persistence of the hepatitis B virus infection, measured by the presence of hepatitis B early antigen and hepatitis B virus DNA (polymerase chain reaction and hybridization) at 12 months of follow-up, was observed in I of 33 patients in the UDCA group and in 6 of 25 patients in the placebo group (p = 0.02). Gallstones detected by entry ultrasound dissolved in four of eight cases in the UDCA group and in none of six in the placebo group. We conclude that UDCA has a beneficial effect on the course of the acute viral hepatitis. It may enhance the clearance of the hepatitis B virus and thus prevent the development of chronic hepatitis." ]

In order to correct fetal presentation, the stimulation of the acupoint BL67 by moxibustion, acupuncture or both has been proposed. Since no studies had previously been carried out on Western populations, pregnant Italian women at 33-35 weeks gestational age carrying a fetus in breech presentation were enrolled in a randomized, controlled trial involving an active BL67 point stimulation and an observation group.\n A total of 240 women at 33-35 weeks of gestation carrying a fetus in breech presentation were randomized to receive active treatment (acupuncture plus moxibustion) or to be assigned to the observation group. Bilateral acupuncture plus moxibustion was applied at the BL67 acupoint (Zhiyin). The primary outcome of the study was fetal presentation at delivery.\n Fourteen cases dropped out. The final analysis was thus made on 226 cases, 114 randomized to observation and 112 to acupuncture plus moxibustion. At delivery, the proportion of cephalic version was lower in the observation group (36.7%) than in the active-treatment group (53.6 %) (p = 0.01). Hence, the proportion of Cesarean sections indicated for breech presentation was significantly lower in the treatment group than in the observation group (52.3% vs. 66.7%, p = 0.03).\n Acupuncture plus moxibustion is more effective than observation in revolving fetuses in breech presentation. Such a method appears to be a valid option for women willing to experience a natural birth.", "Traditional Chinese medicine uses moxibustion (burning herbs to stimulate acupuncture points) of acupoint BL 67 (Zhiyin, located beside the outer corner of the fifth toenail), to promote version of fetuses in breech presentation. Its effect may be through increasing fetal activity. However, no randomized controlled trial has evaluated the efficacy of this therapy.\n To evaluate the efficacy and safety of moxibustion on acupoint BL 67 to increase fetal activity and correct breech presentation.\n Randomized, controlled, open clinical trial.\n Outpatient departments of the Women's Hospital of Jiangxi Province, Nanchang, and Jiujiang Women's and Children's Hospital in the People's Republic of China.\n Primigravidas in the 33rd week of gestation with normal pregnancy and an ultrasound diagnosis of breech presentation.\n The 130 subjects randomized to the intervention group received stimulation of acupoint BL 67 by moxa (Japanese term for Artemisia vulgaris) rolls for 7 days, with treatment for an additional 7 days if the fetus persisted in the breech presentation. The 130 subjects randomized to the control group received routine care but no interventions for breech presentation. Subjects with persistent breech presentation after 2 weeks of treatment could undergo external cephalic version anytime between 35 weeks' gestation and delivery.\n Fetal movements counted by the mother during 1 hour each day for 1 week; number of cephalic presentations during the 35th week and at delivery.\n The intervention group experienced a mean of 48.45 fetal movements vs 35.35 in the control group (P<.001; 95% confidence interval [CI] for difference, 10.56-15.60). During the 35th week of gestation, 98 (75.4%) of 130 fetuses in the intervention group were cephalic vs 62 (47.7%) of 130 fetuses in the control group (P<.001; relative risk [RR], 1.58; 95% CI, 1.29-1.94). Despite the fact that 24 subjects in the control group and 1 subject in the intervention group underwent external cephalic version, 98 (75.4%) of the 130 fetuses in the intervention group were cephalic at birth vs 81 (62.3%) of the 130 fetuses in the control group (P = .02; RR, 1.21; 95% CI, 1.02-1.43).\n Among primigravidas with breech presentation during the 33rd week of gestation, moxibustion for 1 to 2 weeks increased fetal activity during the treatment period and cephalic presentation after the treatment period and at delivery.", "The aim of the study was to evaluate cardiovascular effects and fetal behavior during moxibustion, acupuncture or acupuncture plus moxibustion applied on the BL.67 acupoint of women (beside the outer corner of the 5th toenail) in fetal breech presentation. During the acupoint stimulation (20 min, two times a week), the women were submitted to computerized non-stress test. Fourteen cases were treated by both acupuncture and moxibustion, 15 cases by moxibustion and 10 cases by acupuncture. In 56% of cases, fetal position was converted from breech position to cephalic one; the success share was 80% for moxibustion, 28% for acupuncture, 57% for acupuncture plus moxibustion; the conversion, on average, was achieved after 3 sessions. Statistical analysis indicated that acupuncture plus moxibustion was able to reduce fetal heart rate during the application of stimuli while acupuncture and moxibustion separately did not affect such parameter. Moreover, moxibustion and acupuncture with moxibustion reduced fetal movements while acupuncture only appears ineffective. The present study suggests that fetal movements were reduced by both acupuncture plus moxibustion and moxibustion and that fetal heart rate was reduced just by acupuncture plus moxibustion. The mechanisms leading the effect on fetal heart rate and fetal movements remain to be clarified. Even though further studies are needed, such preliminar report mainly investigated the impact of different stimula on the BL.67 acupoint. Unfortunately these small series of data do not allow us to draw any conclusion about the effectiveness of the different treatments." ]

In a prospective, randomized, double-blind, placebo-controlled study, 372 women under spinal anesthesia received 8 mg of dexamethasone or placebo intravenously just after the umbilical cord was clamped. The rate of PDPH and correlated risk factors were evaluated. The prevalence of nausea and vomiting in the dexamethasone and placebo groups was 54.4 and 51.7%, respectively. There was no statistically meaningful difference between the results (P value = 0.673). The overall incidence rate of PDPH was 10.8%, with 28 cases from the dexamethasone group compared with 11 subjects from the placebo group (P value = 0.006). This effect was most prominent on the first day (P value = 0.046) and disappeared on the second day after spinal anesthesia (P value = 0.678). Prophylactic treatment with 8 mg of dexamethasone not only increases the severity and incidence of PDPH, but is also ineffective in decreasing the prevalence of intra-operative nausea and vomiting during cesarean section.

After delivery, patients were randomly assigned to one of two equal-sized groups. In group I (cosyntropin group), patients received cosyntropin in a dose of 1 mg intravenously. In group II (control group), patients received an equal volume of normal saline.\n Fifteen patients (33%) in the cosyntropin group suffered from PDPH, compared with 31 patients (68.9%) in the control group (P = 0.001). Significantly fewer patients in the cosyntropin group required an EBP, compared with the control group (5 patients [11.1%] vs. 13 patients [28.9%], respectively; P = 0.035). The Kaplan-Meier curves for the occurrence of PDPH showed a hazard ratio of 0.32 (95% CI = 0.16-0.55, P < 0.0001). The time from ADP to occurrence of PDPH was significantly longer in the cosyntropin group (27.2 [7.7] h) in comparison with the control group (17.5 [4.9] h; P < 0.001). However, there were no statistically significant differences among patients who developed PDPH in both groups with regard to the severity or duration of PDPH or with regard to the need for EBP or for repeat EBP (P > 0.05).\n Administration of cosyntropin after ADP in parturients was associated with significant reduction in the incidence of PDPH and need for EBP and significant prolongation of the time from ADP to occurrence of PDPH.", "Low-dose intrathecal (spinal) morphine (0.1-0.2 mg) for Caesarean section delivers excellent postoperative analgesia but is associated with significant nausea and vomiting.

Spinal anaesthesia consisted of: hyperbaric bupivacaine 0.5%, 2.0 ml; fentanyl 10 micro g; and spinal morphine 0.2 mg. The primary outcome measure was the incidence of nausea.\n The incidence of nausea was significantly less in patients receiving cyclizine compared with dexamethasone and placebo (33 vs 60 and 67%, respectively, P<0.05). Severity of nausea and number of vomiting episodes were also less at 3-6 h in cyclizine patients. Overall satisfaction with postoperative care at 24 h, expressed on a 100 mm visual analogue scale, was greater in cyclizine [78 (28)] than either dexamethasone [58 (31), P=0.03] or placebo [51 (28), P=0.008].\n We conclude that following spinal morphine 0.2 mg and fentanyl 10 micro g analgesia for Caesarean section, cyclizine 50 mg i.v. reduces the incidence of nausea compared with dexamethasone 8 mg i.v. or placebo.

This study prospectively compared the incidence of PDPH with two spinal needles of different size and design: the 24-gauge Sprotte (noncutting point) versus the 25-gauge Quincke (diamond, cutting point). The hypothesis that subarachnoid fentanyl will reduce the incidence of PDPH, as suggested in the literature, was also studied.\n Only patients for emergency or elective cesarean delivery were studied. One hundred ninety four patients were randomly assigned to receive spinal anesthesia with one of the two needles (Sprotte, n = 96; Quincke, n = 98).

All patients were evaluated during the first 4 postoperative days, and follow-up telephone interviews were conducted 3 weeks after discharge.\n Four patients (4.2%) in the Sprotte group and seven (7.1%) in the Quincke group developed PDPH. Three out of four patients with headache in the Sprotte and four out of seven in the Quincke group received fentanyl as an adjunct for spinal anesthesia. Two patients in the Sprotte group required an epidural blood patch as a therapy for PDPH. Two patients in the Quincke group had severe headache and required an epidural blood patch.\n In the current study, the use of the 24-gauge Sprotte spinal needle resulted in a low incidence of severe PDPH, but was not significantly different when compared with the use of a 25-gauge Quincke needle (oriented parallel to the longitudinal dural fibers).

This study sought to compare detoxification programs using these medications with regard to side-effects and related distress, general well-being, perceived self-efficacy and social support. A total of 200 treatment-seeking heroin-dependent patients, aged 18-50, were randomly assigned to buprenorphine or clonidine inpatient withdrawal treatments over 10days followed by 11days of relapse prevention measures. A semi-structured interview and a battery of self-rating scales assessing parameters of the interest were administered to the patients who completed the 10-day detoxification protocol with buprenorphine (n=90) and clonidine (n=50). Chi-square statistics and analysis of covariance were performed to examine between-group differences. Compared with patients treated with clonidine, patients who received buprenorphine developed significantly less side-effects and related distress, and had higher senses of well-being, self-efficacy and social support. The findings suggest that buprenorphine is preferable for inpatient detoxification due to its side-effects profile and positive effects on well-being and psychosocial variables. These early benefits of buprenorphine could enable consequent maintenance treatment.", "Thirty-nine methadone maintenance patients were included in a 9-day, double blind, randomized, inpatient detoxification trial. Methadone was tapered to 10 mg/day and then patients were assigned to one of these 3 protocols: clonidine (0.3-0.9 mg/day), lefetamine (60-240 mg/day), buprenorphine (0.15-0.9 mg/day). Buprenorphine treatment was significantly superior to clonidine and to lefetamine (F = 3.96 df = 2, 29 P < 0.05) in controlling objective, subjective and psychological withdrawal symptomatology. Clonidine was more effective than lefetamine in suppressing withdrawal in the first 3 days of treatment (day 3: F = 4.10 df = 2, 30 P < 0.05), and this trend was apparent on the objective and psychological items.

Performance on these measures was virtually identical between the latter two groups. No serious adverse health effects attributable to buprenorphine were noted.\n Buprenorphine maintenance at 8 mg/d appears to be less than optimally efficacious under the conditions of the present study.

The study was conducted from February to July 2004 in the outpatient drug user treatment center at University Department of Psychiatry at Innsbruck, providing maintenance treatment programs and detoxification in Tyrol, Austria. One hundred twenty opioid users seeking treatment were compared with 120 opioid-dependent patients retained for 6 months on a slow-release oral morphine, methadone, or sublingual buprenorphine maintenance program. The German version (\"Berlin Quality of Life Profile\") of the Lancashire Quality of Life Profile was used, and illicit opioid use was determined by urinalysis. Physical symptoms were measured by using the Opioid Withdrawal Scale. Urinalyses revealed a significantly lower consumption of cocaine and opioids in all three substitution groups than in patients at admission (p < 0.001 and p < or = 0.004, respectively).

Slow-release oral morphine is a well-established treatment for pain, but more research is required to evaluate it as a treatment for heroin dependence. The present data indicate that slow-release oral morphine could have some disadvantages compared with sublingual buprenorphine and methadone in QOL, physical symptoms, and additional consumption. The results further suggest that buprenorphine treatment is as effective as methadone in effects on quality of life and physical symptoms.", "With the growing role of intravenous drug use in the transmission of HIV infection, HIV-infected patients frequently present with comorbid opioid dependence. Yet, few empirical evaluations of the efficacy and consequences of opioid detoxification medications in medically ill HIV-infected patients have been reported. In a randomized, double-blind clinical trial, we evaluated the impact of three medications on the signs and symptoms of withdrawal and on the pain severity in heroin-dependent HIV-infected patients (N=55) hospitalized for medical reasons on an inpatient AIDS service. Patients received a 3-day pharmacologic taper with intramuscular buprenorphine (n=21), oral clonidine (n=16), or oral methadone (n=18), followed by a clonidine transdermal patch on the fourth day. Observed and self-reported measures of opioid withdrawal and pain were taken 1-3 times daily for up to 4 days. Opiate administration used as medically indicated for pain was also recorded. Observer- and subject-rated opiate withdrawal scores decreased significantly following the first dose of medication and overall during treatment. Among all 55 subjects, self-reported and observer-reported pain decreased after treatment (on average observer-rated opioid withdrawal scale (OOWS) scores declined 5.6 units and short opioid withdrawal scale (SOWS) declined 4.8 units, P<0.001, for both) with no indication of increased pain during medication taper. There were no significant differences of pain decline and other measures of withdrawal between the three treatment groups. During the intervention period, supplemental opiates were administered as medically indicated for pain to 45% of the patients; only 34% of men versus 62% of women received morphine (P<0.05). These findings suggest buprenorphine, clonidine, and methadone regimens each decrease opioid withdrawal in medically ill HIV-infected patients.", "In recent years, interest in shortening of opioid detoxification has increased with the rising demands to find more cost-effective approaches for treatment of opioid dependence. This study was designed to evaluate the efficacy of administration of high doses of buprenorphine during 24 h in the management of acute opioid withdrawal. A total of 40 treatment-seeking opioid dependents were admitted and randomly assigned to two groups in a double blind, parallel trial. Buprenorphine was administered intramuscularly. Twenty patients received 12 mg buprenorphine in 24 h and the remaining 20 patients treated with conventional doses of buprenorphine tapered down over 5 days. Variables that were assessed included retention in treatment, rates of successful detoxification, the Subjective Opiate Withdrawal Scale (OOWS) scores, the Objective Opiate Withdrawal Scale (SOWS) scores, intensity of craving, drug side effects, and levels of hepatic enzymes (ALT and AST). There was no significant difference between the two groups on most variables. The main difference was in the time that maximal withdrawal symptoms occurred, which in the experimental protocol group appeared early while in the conventional protocol group appeared later during the detoxification period. Moreover, the experimental protocol was not only tolerated well but also accompanied with significantly less elevation in the ALT levels compared to the conventional treatment. However, patients in this group used more indomethacin and trazodone for symptom palliation. This study suggests that administration of high doses of buprenorphine in 24 h may be a reasonable approach for shortening of opioid detoxification. However, a larger study to confirm our results is warranted.", "Buprenorphine, a partial mu-agonist and kappa-antagonist, has been proposed as an alternative to methadone for maintenance treatment of opioid dependence, especially for patients with concurrent cocaine dependence or abuse. This study evaluated whether higher maintenance doses of buprenorphine and methadone are superior to lower doses for reducing illicit opioid use and whether buprenorphine is superior to methadone for reducing cocaine use.\n A total of 116 subjects were randomly assigned to 1 of 4 maintenance treatment groups involving higher or lower daily doses of sublingual buprenorphine (12 or 4 mg) or methadone (65 or 20 mg) in a double-blind, 24-week clinical trial. Outcome measures included retention in treatment and illicit opioid and cocaine use as determined by urine toxicology testing and self-report.\n There were significant effects of maintenance treatment on rates of illicit opioid use, but no significant differences in treatment retention or the rates of cocaine use. The rates of opioid-positive toxicology tests were lowest for treatment with 65 mg of methadone (45%), followed by 12 mg of buprenorphine (58%), 20 mg of methadone (72%), and 4 mg of buprenorphine (77%), with significant contrasts found between 65 mg of methadone and both lower-dose treatments and between 12 mg of buprenorphine and both lower-dose treatments.\n The results support the superiority of higher daily buprenorphine and methadone maintenance doses vs lower doses for reducing illicit opioid use, but the results do not support the superiority of buprenorphine compared with methadone for reducing cocaine use.", "Rapid opioid detoxification with opioid antagonist induction using general anesthesia has emerged as an expensive, potentially dangerous, unproven approach to treat opioid dependence.\n To determine how anesthesia-assisted detoxification with rapid antagonist induction for heroin dependence compared with 2 alternative detoxification and antagonist induction methods.\n A total of 106 treatment-seeking heroin-dependent patients, aged 21 through 50 years, were randomly assigned to 1 of 3 inpatient withdrawal treatments over 72 hours followed by 12 weeks of outpatient naltrexone maintenance with relapse prevention psychotherapy. This randomized trial was conducted between 2000 and 2003 at Columbia University Medical Center's Clinical Research Center. Outpatient treatment occurred at the Columbia University research service for substance use disorders. Patients were included if they had an American Society of Anesthesiologists physical status of I or II, were without major comorbid psychiatric illness, and were not dependent on other drugs or alcohol.\n Anesthesia-assisted rapid opioid detoxification with naltrexone induction, buprenorphine-assisted rapid opioid detoxification with naltrexone induction, and clonidine-assisted opioid detoxification with delayed naltrexone induction.\n Withdrawal severity scores on objective and subjective scales; proportions of patients receiving naltrexone, completing inpatient detoxification, and retained in treatment; proportion of opioid-positive urine specimens.\n Mean withdrawal severities were comparable across the 3 treatments. Compared with clonidine-assisted detoxification, the anesthesia- and buprenorphine-assisted detoxification interventions had significantly greater rates of naltrexone induction (94% anesthesia, 97% buprenorphine, and 21% clonidine), but the groups did not differ in rates of completion of inpatient detoxification. Treatment retention over 12 weeks was not significantly different among groups with 7 of 35 (20%) retained in the anesthesia-assisted group, 9 of 37 (24%) in the buprenorphine-assisted group, and 3 of 34 (9%) in the clonidine-assisted group. Induction with 50 mg of naltrexone significantly reduced the risk of dropping out (odds ratio, 0.28; 95% confidence interval, 0.15-0.51). There were no significant group differences in proportions of opioid-positive urine specimens. The anesthesia procedure was associated with 3 potentially life-threatening adverse events.\n These data do not support the use of general anesthesia for heroin detoxification and rapid opioid antagonist induction.", "Clinical efficacy of buprenorphine in controlling withdrawal symptoms was compared against clonidine among 44 opiate dependent males. Subjective and objective withdrawal symptoms were assessed by withdrawal rating scales daily for 10 days. The subjects were randomly assigned to fixed dose schedule of either buprenorphine (0.6-1.2 mg per day, sublingually) or clonidine (0.3-0.9 mg per day, oral) for 10 days. Buprenorphine was found superior to clonidine in alleviating most of the subjective and objective opiate withdrawal symptoms. Subjective symptoms declined earlier among the subjects receiving buprenorphine. No untoward side-effects of buprenorphine were noticed.", "To assess the efficacy of buprenorphine for short-term maintenance/detoxification.\n A randomized, double-blind, parallel group study comparing buprenorphine, 8 mg/d, methadone, 60 mg/d, and methadone, 20 mg/d, in a 17-week maintenance phase followed by an 8-week detoxification phase.\n Outpatient facilities at the Addiction Research Center, Baltimore, Md.\n One hundred sixty-two volunteers seeking treatment for opioid dependence.\n In addition to the medication, counseling using a relapse prevention model was offered but not required.\n Retention time in treatment, urine samples negative for opioids, and failure to maintain abstinence.\n Throughout the maintenance phase, retention rates were significantly greater for buprenorphine (42%) than for methadone, 20 mg/d (20%, P less than .04); the percentage of urine samples negative for opioids was significantly greater for buprenorphine (53%, P less than .001) and methadone, 60 mg/d (44%, P less than .04), than for methadone, 20 mg/d (29%). Failure to maintain abstinence during the maintenance phase was significantly greater for methadone, 20 mg/d, than for buprenorphine (P less than .03). During the detoxification phase, no differences were observed between groups with respect to urine samples negative for opioids. For the entire 25 weeks, retention rates for buprenorphine (30%, P less than .01) and methadone, 60 mg/d (20%, P less than .05), were significantly greater than for methadone, 20 mg/d (6%). All treatments were well tolerated, with similar profiles of self-reported adverse effects. The percentages of patients who received counseling did not differ between groups.\n Buprenorphine was as effective as methadone, 60 mg/d, and both were superior to methadone, 20 mg/d, in reducing illicit opioid use and maintaining patients in treatment for 25 weeks.", "Opioid detoxification in a primary care setting followed by ongoing substance abuse treatment may be appropriate for selected opioid-dependent patients.\n To compare three pharmacologic protocols for opioid detoxification in a primary care setting.\n Randomized, double-blind clinical trial with random assignment to treatment protocols.\n A free-standing primary care clinic affiliated with drug treatment programs.\n 162 heroin-dependent patients.\n Three detoxification protocols: donidine, combined donidine and naltrexone, and buprenorphine.\n Successful detoxification (that is, when study participants received a full opioid-blocking dose [50 mg] of naltrexone), treatment retention (8 days), and withdrawal symptoms.\n Overall, 65% of participants (36 of 55) who received clonidine, 81% (44 of 54) who received combined clonidine and naltrexone, and 81% (43 of 53) who received buprenorphine were successfully detoxified. Retention did not differ significantly across the groups: 65% of participants (36 of 55) who received clonidine, 54% (29 of 54) who received combined clonidine and naltrexone, and 60% (32 of 53) who received buprenorphine. Participants who received buprenorphine had a significantly lower mean withdrawal symptom score than those who received clonidine or combined clonidine and naltrexone.\n Participants in the combined clonidine and naltrexone group and those in the buprenorphine group were more likely to complete detoxification, although retention at 8 days did not differ among the groups. Participants who were assigned to the buprenorphine group experienced less severe withdrawal symptoms than those assigned to the other two groups.", "The spontaneous physical dependence of buprenorphine was assessed in opioid addicts who switched from heroin to sublingual or intravenous buprenorphine. Twenty-two patients were randomly assigned to double-blind administration of methadone (n = 11) or placebo (n = 11) for 13 days after abrupt withdrawal of buprenorphine. Methadone was administered according to four pre-established dosing schedules depending on the previous amount of daily consumed buprenorphine. No methadone-treated patient required modification of the therapeutic regimen, whereas eight of eleven placebo-treated patients needed treatment with methadone. Buprenorphine withdrawal syndrome was of opioid type, began somewhat more slowly, and showed a peak until day 5. The occurrence, time-course and characteristics of buprenorphine withdrawal syndrome make it necessary to reconsider the abuse potential of this analgesic.", "Buprenorphine at 2 mg and 6 mg daily was compared with methadone at 35 mg and 65 mg during 24 weeks of maintenance among 125 opioid-dependent patients. As hypothesized, 6 mg of buprenorphine were superior to 2 mg of buprenorphine in reducing illicit opioid use, but higher dosage did not improve treatment retention. Self-reported illicit opioid use declined substantially in all groups, but by the third month, significantly more heroin abuse was reported at 2 mg than at 6 mg of buprenorphine or of methadone. From an initial average of $1860/month, month 3 usage dropped to $41 (methadone 65 mg), $73 (methadone 35 mg), $118 (buprenorphine 6 mg), and $351/month (buprenorphine 2 mg). Days of use also dropped from 29 days to 1.7 (methadone 65 mg), 2.8 (methadone 35 mg), 4.0 (buprenorphine 6 mg), and 6.6 days/month (buprenorphine 2 mg). This relatively low efficacy for 2 mg of buprenorphine persisted through month 6 of the trial, with 7.2 days/month and $235/month of use for buprenorphine at 2 mg versus 1.9 days/month and $65/month for the other three groups. Increased opioid abuse also was associated with significantly greater and persistent opioid withdrawal symptoms. Our secondary hypothesis, that buprenorphine would be equivalent to methadone in efficacy, was not supported. Treatment retention was significantly better on methadone (20 vs. 16 weeks), and methadone patients had significantly more opioid-free urines (51% vs. 26%). Abstinence for at least 3 weeks was also more common on methadone than buprenorphine (65% vs. 27%).(ABSTRACT TRUNCATED AT 250 WORDS)" ]

[ "In 1995 a meta-analysis of randomised trials investigating the value of adding chemotherapy to primary treatment for non-small cell lung cancer (NSCLC) suggested a small survival benefit for cisplatin-based chemotherapy in each of the primary treatment settings. However, the meta-analysis included many small trials and trials with differing eligibility criteria and chemotherapy regimens.\n The aim of the Big Lung Trial was to confirm the survival benefits seen in the meta-analysis and to assess quality of life and cost in the supportive care setting. A total of 725 patients were randomised to receive supportive care alone (n = 361) or supportive care plus cisplatin-based chemotherapy (n = 364).\n 65% of patients allocated chemotherapy (C) received all three cycles of treatment and a further 27% received one or two cycles. 74% of patients allocated no chemotherapy (NoC) received thoracic radiotherapy compared with 47% of the C group. Patients allocated C had a significantly better survival than those allocated NoC: HR 0.77 (95% CI 0.66 to 0.89, p = 0.0006), median survival 8.0 months for the C group v 5.7 months for the NoC group, a difference of 9 weeks. There were 19 (5%) treatment related deaths in the C group. There was no evidence that any subgroup benefited more or less from chemotherapy. No significant differences were observed between the two groups in terms of the pre-defined primary and secondary quality of life end points, although large negative effects of chemotherapy were ruled out. The regimens used proved to be cost effective, the extra cost of chemotherapy being offset by longer survival.\n The survival benefit seen in this trial was entirely consistent with the NSCLC meta-analysis and subsequent similarly designed large trials. The information on quality of life and cost should enable patients and their clinicians to make more informed treatment choices." ]

[ "The purpose of the study was to determine whether early postoperative enteral feeding with an immune-enhancing formula (IEF) decreases morbidity, mortality, and length of hospital stay in patients with upper gastrointestinal (GI) cancer.\n Early enteral feeding with an IEF has been associated with improved outcome in trauma and critical care patients. Evaluable data documenting reduced complications after major upper GI surgery for malignancy with early enteral feeding are limited.\n Between March 1994 and August 1996, 195 patients with a preoperative diagnosis of esophageal (n = 23), gastric (n = 75), peripancreatic (n = 86), or bile duct (n = 11) cancer underwent resection and were randomized to IEF via jejunostomy tube or control (CNTL). Tube feedings were supplemented with arginine, RNA, and omega-3 fatty acids, begun on postoperative 1, and advanced to a goal of 25 kcal/kg per day. The CNTL involved intravenous crystalloid solutions. Statistical analysis was by t test, chi square, or logistic regression.\n Patient demographics, nutritional status, and operative factors were similar between the groups. Caloric intake was 61% and 22% of goal for the IEF and CNTL groups, respectively. The IEF group received significantly more protein, carbohydrate, lipids and immune-enhancing nutrients than did the CNTL group. There were no significant differences in the number of minor, major, or infectious wound complications between the groups. There was one bowel necrosis associated with IEF requiring reoperation. Hospital mortality was 2.5% and median length of hospital stay was 11 days, which was not different between the groups.\n Early enteral feeding with an IEF was not beneficial and should not be used in a routine fashion after surgery for upper GI malignancies.", "Patients undergoing major gastrointestinal surgery who had a prognostic nutritional index (PNI) score of greater than 30% were randomized to receive a preoperative course of 10 days of intravenous nutrition or to undergo surgery at the next convenient operation list. Two groups of 17 patients were well matched for age, sex, and nutritional status. Although they underwent diverse operations, the extent of these was similar: 12 +/- 3 days of parenteral nutrition resulted in weight gain, 3.2 +/- 2.3 kg p less than 0.01; increased triceps skinfold, 0.6 +/- 1.2 mm p less than 0.05; improved immunological state, p less than 0.02; and improved PNI, 5.5 +/- 10.1% p less than 0.05. The changes in serum albumin and transferrin were not significant. There were only three major complications with one death in the treatment group but this was not significantly different from the control group which had six major complications and three deaths. This study suggests that patients with demonstrable nutritional depletion who require major gastrointestinal surgery will benefit from a preoperative course of parenteral nutrition, but to conclusively prove this a large and probably multicentre study will be required.", "Ever since methods of artificial nutritional support became available, attempts have been made using this form of treatment to reduce mortality and morbidity in surgical patients. Many trials have addressed this question, but very few have given a meaningful answer because of conceptual and methodological flaws. We therefore undertook a prospective randomised trial investigating the effects of at least 10 days pre-operative total parenteral nutrition (TPN) (n = 51) or total enteral nutrition (TEN) (n = 50) providing 150% basal energy expenditure (BEE) non-protein energy, to reduce major postoperative complications and mortality in a homogeneous patient group with signs of depletion. 50 patients served as a depleted control group (D) and 49 patients served as a non-depleted reference group (ND) and were operated upon without delay. Depleted control patients suffered significantly more septic complications than did patients in the non-depleted reference group (p < 0.05). There was no significant difference, however, in septic complications between either of the nutritional support groups and the non-depleted control group. In high risk patients, with weight loss >10% of body weight and over 500 ml blood loss during operation, a significant decrease in major complications was observed (p < 0.05) as a result of nutritional support. We conclude that pre-operative nutritional support, in patients with severe depletion, results in a reduction in major complications to a degree that justifies its routine use in this selected group of patients.", "Postoperative oral nutritional supplementation has been shown to be of clinical benefit. This study examined the clinical effects and cost of administration of oral supplements both before and after surgery.\n This was a randomized clinical trial conducted in three centres. Patients undergoing lower gastrointestinal tract surgery were randomized to one of four groups: group CC received no nutritional supplements, group SS took supplements both before and after surgery, group CS received postoperative supplements only, and group SC were given supplements only before surgery. Preoperative supplements were given from the time it was decided to operate to 1 day before surgery. Postoperative supplements were started when the patient was able to take free fluids and continued for 4 weeks after discharge from hospital. Data collected included weight change, complications, length of stay, nutritional intake, anthropometrics, quality of life and detailed costings covering all aspects of care.\n Some 179 patients were randomized, of whom 27 were withdrawn and 152 analysed (CC 44, SS 32, CS 35, SC 41). Dietary intake was similar in all four groups throughout the study. Mean energy intake from preoperative supplements was 536 and 542 kcal/day in the SS and SC groups respectively; that 2 weeks after discharge from hospital was 274 and 361 kcal/day in the SS and CS groups respectively. There was significantly less postoperative weight loss in the SS group than in the CC and CS groups (P < 0.050), and significantly fewer minor complications in the SS and CS groups than the CC group (P < 0.050). There were no differences in the rate of major complications, anthropometrics and quality of life. Mean overall costs were greatest in the CC group, although differences between groups were not significant.\n Perioperative oral nutritional supplementation started before hospital admission for lower gastrointestinal tract surgery significantly diminished the degree of weight loss and incidence of minor complications, and was cost-effective.\n Copyright 2004 British Journal of Surgery Society Ltd.", "In a comparative clinical trial to examine the influence of 10 days of preoperative parenteral nutrition (PPN) on the postoperative complication rate for gastrointestinal carcinoma 59 patients (controls) received the regular hospital diet and 66 received PPN. The two groups were similar in nutritional status and in distribution of site and stage of tumour and type of operation. The rates of postoperative wound infection, pneumonia, major complications, and mortality were generally lower in the PPN group, but the differences were significant only for major complications and mortality. The clinical results can be explained by the improvement in various indices of humoral and cellular immunocompetence and the protein status in the PPN group and their deterioration in the control group during the preoperative course.", "Patients who undergo surgery are at risk of malnutrition due to periods of starvation, the stress of surgery, and subsequent increase in metabolic rate. There are limited data on nutritional outcome of surgical patients.\n To investigate changes in nutritional status and the influence of oral supplements on nutritional status, morbidity, and quality of life in postoperative surgical patients.\n Entry was determined by the presence of malnutrition, as defined by a body mass index (BMI) < or =20 kg/m(2), anthropometric measurements < or =15th percentile on admission, or initiation of oral diet postoperatively and/or a weight loss of 5% or more during the operative period. We studied 101 patients: 52 were randomised to the treatment group (TG) and prescribed a 1.5 kcal/ml nutritional supplement; 49 patients were randomised to the control group (CG) and continued with routine nutritional management. Nutritional status was assessed by weight, anthropometry, and grip strength, with measurements taken at two weekly intervals for 10 weeks. Complications, namely wound infection, chest infection, and antibiotic use were documented. Quality of life (QOL) was assessed using the UK SF-36 questionnaire.\n Patients in the control group lost a maximum mean (SD) of 5.96 (4.21) kg in weight over a period of eight weeks while patients in group TG lost less weight overall (maximum mean (SD) 3.40 (0.89) kg (p<0.001) occurring at four weeks and progressively regained weight from week 4). Anthropometry, grip strength, and QOL were similarly significantly different between groups (p<0.001). Fewer patients in the treatment group (7/52) required antibiotic prescriptions compared with the control group (15/49).\n Nutritional status declined for two months after discharge. Postoperative nutritional supplementation improved nutritional status, QOL, and morbidity in these patients.", "The effects of total parenteral nutrition (TPN) versus enteral nutrition (TEN) were studied in 34 patients following major neurosurgery. Measurements were made of resting energy expenditure (REE), urea production rate (UPR), visceral proteins, parameters of liver and pancreas function, as well as gastrointestinal absorption. To predict nutritional status, nutritional index (NI) was calculated. UPR revealed no significant differences between the groups. After 12 days of TEN, however, synthesis of visceral proteins increased significantly. In addition, NI improved after TEN (p < 0.05), whereas it remained unchanged after TPN. Thrombocyte and lymphocyte counts rose predominately during enteral nutrition. Only in the TEN group was REE increased by 18% and Glasgow Coma Scale (GCS) enhanced from Day 6 on. Exogenous insulin demand was enhanced in the parenterally fed group, and bilirubin (p < 0.05), amylase (p < 0.05), and lipase (p < 0.01) rose significantly, as did gamma-glutamyl-transferase (p < 0.0005) and alkaline phosphatase (p < 0.0005). After 12 d of TPN, vitamin A absorption was significantly attenuated, indicating reduced fat absorption compared to TEN. Carbohydrate absorption did not show significant changes between the groups. Only during TPN did mean values of xylose absorption remain below the normal range. Therefore, enteral nutrition following neurosurgical procedures is associated with an accelerated normalization of nutritional status and an improved substrate tolerance. TEN opposes early postoperative absorption disturbances of the small intestine.", "It has been suggested that the routine provision of oral dietary supplements (ODS) in postoperative surgical patients is of benefit in terms of morbidity and length of hospital stay. The aim of this study was to evaluate the effects of both pre- and postoperative ODS in patients undergoing an elective laparotomy. Patients requiring elective major gastrointestinal surgery were prospectively randomized into one of four groups: Group I received ODS in addition to normal diet both pre- and postoperatively, Group II were given ODS in the preoperative period only, Group III received ODS only in the postoperative period, and Group IV did not receive any supplements. Assessments of nutritional status, voluntary food intake, weight loss, serum albumin, morbidity and mortality, anxiety and depression, and postoperative activity levels were performed, and comparisons made between the groups. One hundred patients were included in the study. The mean daily energy intake from preoperative ODS was 507 +/- 140 kcal, significantly more than the 252 +/- 195 kcal in the postoperative period (P < 0.001). The postoperative voluntary food intake in patients receiving ODS was not significantly different from that in patients receiving normal diet alone (1090 versus 1268 kcal, 46.2 versus 49.1 g protein, P > 0. 05). All groups demonstrated an overall weight loss, with no significant differences between the groups, and there was no demonstrable effect on clinical outcome. At 6 mo postoperatively there were no differences between the study groups in terms of levels of activity. These results suggest that the routine use of perioperative ODS in well-nourished patients undergoing major gastrointestinal surgery confers no clinical or functional benefit.", "To compare the efficacy of early total enteral nutrition (TEN) vs. total parenteral nutrition (TPN) in patients with severe acute pancreatitis (SAP).\n A total of 22 consecutive patients with SAP were randomized to receive TPN (group I) or TEN (group II). SAP was defined applying APACHE II score, C-reactive protein (CRP) measurements and/or Balthazar CT scan score. Acute inflammatory response (CRP, TNF-a, IL-6), visceral proteins (pre-albumin, albumin), complications (systemic inflammatory response syndrome, multiorgan failure, infections), surgical interventions, length of hospital stay and mortality were evaluated.\n No significant differences were found between the two groups in the APACHE II score, in CRP, TNF-a and IL-6 concentrations or in pre-albumin and albumin levels over the first 10 days. Seven patients in group I and 4 in group II suffered severe complications. Three patients in group I required surgical intervention. Length of hospital stay was alike in the two groups. Two patients from group I died in the course of the hospitalization.\n SAP patients with TEN feeding showed a tendency towards a better outcome than patients receiving TPN.", "To determine the effect of early enhanced enteral nutrition (EN) on clinical outcome of head-injured patients.\n Prospective, randomized, controlled trial.\n Tertiary neurosurgical and trauma center.\n Eighty-two patients suffering head injury and requiring mechanical ventilation.\n Patients were randomized to receive standard EN (gradually increased from 15 mL/hr up to estimated energy and nitrogen requirements) or enhanced EN (started at a feeding rate that met estimated energy and nitrogen requirements) from day 1. Good neurologic outcome (Glasgow Outcome Scale score of 4 or 5) was determined at 3 and 6 months after injury, and the incidence of infective and total complications was determined during the hospital stay up to 6 months.\n Disease severity assessed by best preintubation Glasgow Coma Scale score, pupillary responses, Injury Severity Score, Acute Physiology and Chronic Health Evaluation II score, computed tomographic scan categorization, and age was similar in both groups. Intervention patients had a higher percentage of energy (p = .0008) and nitrogen (p<.0001) requirements met by EN in the first week after injury. Neurologic outcome at 6 months was similar between groups, but there was a tendency for more intervention patients to have a good neurologic outcome at 3 months than control patients (61% vs. 39%, p = .08). Fewer intervention patients had an infective complication (61% vs. 85%, p = .02) or more than one total complication (37% vs. 61%, p = .046) compared with control patients. Enhanced EN was associated with a reduction in the ratio of serum concentration of C-reactive protein to albumin up to day 6 after injury (p = .004).\n Enhanced EN appears to accelerate neurologic recovery and reduces both the incidence of major complications and postinjury inflammatory responses.", "This study was undertaken to test the hypothesis that early enteral nutrition might reduce the incidence of serious complications after major abdominal surgery.\n In a randomised double blind prospective trial 30 patients received Nutri-drink and 30 patients received placebo through a nasoduodenal feeding tube. On the day of operation the patients were given median 600 ml of either nutrition or placebo, 60 ml per hour. On the first postoperative day the patients received either 1000 ml (median) of nutrition or placebo, on day 2 1200 ml (median) nutrition, 1400 ml placebo, on day 3 1000 ml (median) nutrition, 1150 ml placebo, and on day 4 1000 ml (median) nutrition, 800 ml placebo. All patients were followed up for 30 days by the same investigator.\n The two groups were similar with regard to nutritional status and type of operation. The rate of postoperative infectious complications was significantly lower in the nutrition group, two of 30 compared with 14 of 30 in the placebo group (p = 0.0009).\n Early enteral nutrition given to patients after major abdominal surgery results in an important reduction in infectious complications." ]

[ "The purpose of this study was to determine the effects of prone and supine positioning on the cardiorespiratory stability of preterm infants with apnea and bradycardia.\n A total of 22 preterm infants with symptomatic apnea and bradycardia (gestational age of 26.9 +/- 1.8 weeks and birth weight of 865 +/- 235 gm) were monitored for 24 hours (in four sequential 6-hour blocks) for apnea, bradycardia, and oxygen desaturation in alternating positions (prone or supine) following randomization. Postconceptional age at the time of study was 31.9 +/- 3.0 weeks. Respiratory rate, heart rate, and transcutaneous oxygen saturation were continuously monitored. All episodes of apnea (> or = 10 seconds), bradycardia (< 100 beats per minute), and oxygen desaturation (< 90%) were recorded on an event monitor. Episodes of apnea, bradycardia, and oxygen desaturation were defined as clinically significant if the following criteria were met: apnea, > or = 15 seconds; bradycardia, < 90 beats per minute; and oxygen desaturation, < 80%. All other recorded episodes were considered mild. The episodes were analyzed for statistical significance using the paired t-test.\n No significant differences (p > 0.05) in the incidence of clinically significant apnea, bradycardia, or desaturation between supine and prone positions were seen in these preterm infants.\n Our results suggest that the cardiorespiratory stability of preterm infants is not significantly compromised by supine positioning.", "Respiration, as judged by gas exchange and pulmonary function, is improved in preterm infants kept in the prone rather than the supine position. The influence of position on the breathing pattern as documented by the pneumogram was studied in 14 stable preterm infants with recent clinical apnoea. Ten of the infants had oximetry and nasal flow studies simultaneously with the impedance pneumogram. Each infant had consecutive nocturnal pneumograms, one in the prone, one in the supine position. The infants were kept for more than six hours in the assigned position. A significant increase in apnoea density and in periodic breathing was found in the supine v the prone position (mean (SE) 4.5 (0.7)% v 2.5 (0.5)%, and 13.6 (3.2)% v 7.7 (2.2)%, respectively). There was no positional difference in the incidence of bradycardia and prolonged apnoea. The examination of obstructive apnoea, mixed apnoea, and cyanotic spells did not reveal a consistent disparity between the two positions. These findings indicate an increase in central apnoea in preterm infants kept predominantly in the supine position. Possible relations of positional changes to lung mechanics are discussed. When evaluating pneumograms, attention must be given to the position in which they were performed.", "We investigated whether nursing in the head elevated tilt position (HETP), compared with the horizontal position, has any effect on the incidence of bradycardic and hypoxemic episodes in preterm infants.\n Twelve spontaneously breathing preterm infants with idiopathic recurrent apnea were studied in a randomized controlled crossover trial. Nine infants were treated with aminophylline. Each spent a total of 24 hours in the horizontal prone position and a total of 24 hours in HETP (prone, 15 degrees). The position was changed in random order every 6 hours. Thoracic impedance, heart rate, and arterial oxygen saturation were recorded continuously. The frequency of isolated hypoxemia (arterial saturation <80%), of isolated bradycardia (heart rate <90 beats per minute), and of mixed events was analyzed and compared without knowledge of the allocated position.\n In total, there were significantly fewer bradycardic and/or hypoxemic episodes (28.2%) in HETP compared with the horizontal position (mean difference, 13.35 episodes/24 hours; 95% confidence interval [CI]: 5.9- 20.8). The decrease was largest for isolated hypoxemic episodes (48.5%; mean difference, 11.74 episodes/24 hours; 95% CI: 6.1-17.4). Isolated bradycardic episodes (mean difference, 2.27 episodes/24 hours; 95% CI: -0.78-5.31) and mixed events were not decreased significantly in HETP.\n Nursing in a moderately tilted position (15 degrees) reduces hypoxemic events in preterm infants. This intervention is easy to apply, quickly reversible, and can be combined with drugs such as aminophylline." ]

[ "34 patients suffering from detrusor hyperreflexia due to multiple sclerosis entered the trial and 32 patients accomplished. The patients received each drug for a period of 14 days. The patients made records of relevant symptoms, urgency and urge incontinence and compared the treatment periods according to these symptoms. Registration of the number of micturitions was also made. Furthermore, the patients underwent cystometric studies. The following parameters were recorded and compared: residual urine, volume at the first bladder contraction, effective volume and amplitude of the first bladder contraction. The study showed that the patients preferred methantheline bromide. The entire cystometric pattern changed statistically significant with methantheline bromide, but only with concordance to the patients preferences in 60%. Decrease in number of micturitions and volume at the first bladder contraction were the only parameters showing accordance with the preferences. The drugs caused many various side effects. 12 treatment periods were discontinued due to side effects of meladrazine tartrate. The cystometric recordings seem to be of little use in evaluation of a drugs therapeutic effect, and it is difficult to find parameters which reflect the patients preference of the drugs.", "Therapy of detrusor hyperactivity with anticholinergic agents often is followed by adverse drug reactions. Intravesical application may be an interesting alternative. A randomised, single-blind, placebo-controlled, mono-centre clinical trial was carried out in 84 patients with urgency or urge incontinence. Due to intravesical administration of oxybutynin (CAS 5633-20-5) (n = 21) and trospium chloride (CAS 10405-02-4) (n = 21), respectively, a significant increase in maximum bladder capacity and decrease of detrusor pressure accompanied by an increase of residual urine were found in comparison to placebo in urodynamical investigations. Improvement of uninhibited bladder contractions occurred leading to higher filling volume. Under verapamil (CAS 152-11-4) (n = 21) no marked changes in the efficacy variables were found compared with placebo. All patients completed the study and were assessed with regard to efficacy and safety. No adverse events or marked changes in the vital signs were reported. The immediate onset of effect and the lack of adverse drug reactions suggest that treatment with topical oxybutynin or trospium chloride is an effective alternative in patients with intolerable side effects when orally treated. In addition, intravesical administration may be indicated in patients with bladder spasms due to indwelling catheter or in order to increase bladder capacity before percutaneous cystostomy.", "To determine if there is a significant difference in outcomes of clinical trials funded by industry or not of antimuscarinic medications used to treat overactive bladder (OAB) symptoms and detrusor overactivity (DOA).\n A Medline search was conducted from January 1966 to June 2003 to identify human clinical trials of oxybutynin and tolterodine published in English. Randomized controlled trials on subjects aged > or = 16 years who were being treated with oxybutynin or tolterodine for OAB symptoms or DOA; 24 studies were identified. The endpoints assessed were OAB symptoms or changes in uninhibited detrusor contractions on cystometrography. The outcome variables were dichotomized as 'improvement' or 'no improvement'. Odds ratios and 95% confidence intervals were calculated for each study based on data derived or extracted from tables and figures.\n Meta-analysis showed no significant difference in the outcomes trails funded by industry or not. Trials were then reviewed to determine their adherence to the Consolidated Standards of Reporting Trials (CONSORT) guidelines for randomized trials.\n Clinical trials are important for clinicians when selecting medical therapies. In this analysis we found no difference in outcomes when comparing studies funded by industry or not for tolterodine and oxybutynin. The quality of all trials would be improved by close adherence to the CONSORT guidelines for randomized clinical trials.", "Desmopressin is an approved medical therapy for the treatment of monosymptomatic primary nocturnal enuresis. In cases of limited response to desmopressin, we have added anticholinergic therapy to desmopressin (combination therapy). To evaluate this treatment strategy, we examined the efficacy of combination therapy for primary nocturnal enuresis in desmopressin-nonresponders.\n Only patients with primary nocturnal enuresis refractory to the maximal dosage of desmopressin were enrolled. Children with lower urinary tract symptoms or bowel dysfunction were excluded, on the basis of a 3-day, 24-hour, frequency-volume chart and elimination record. Children continued to take desmopressin and were assigned randomly, in a double-blind manner, to receive either extended-release anticholinergic medication or placebo. Patients were reassessed after 1 month of therapy, with a 1-week nocturnal record.\n Forty-one desmopressin-nonresponders were enrolled, and 7 patients were excluded because of noncompliance. The treatment groups were equally matched with respect to age, gender, functional bladder capacity, and number of wet nights per week. After 1 month of treatment, there was a significant reduction in the mean number of wet nights in the combination therapy group, compared with the placebo group. With a generalized estimating equation approach, there was a significant 66% decrease in the risk of a wet episode, compared with the placebo group.\n This study represents the first prospective, placebo-controlled trial examining the effect of desmopressin in combination with long-acting, anticholinergic, bladder-relaxing therapy for monosymptomatic primary nocturnal enuresis.", "Treatment with the antimuscarinic agents tolterodine and oxybutynin is the mainstay of therapy for overactive bladder, a chronic and debilitating condition characterized by urinary urgency with or without urge incontinence, usually in combination with urinary frequency and nocturia. This study consisted of two trials; in one, patients with overactive bladder were randomized to 8 weeks of open-label treatment with either 2 mg or 4 mg of once-daily extended-release tolterodine (TER), and in the other to 5 mg or 10 mg of extended-release oxybutynin (OER). The study protocol and design were identical for the two trials and site selection ensured that there was no bias in either trial for the tendency of investigators to prescribe one drug rather than the other, or for geographical location. A total of 1289 patients were enrolled, 669 in the tolterodine trial (TER 2 mg, n = 333; TER 4 mg, n = 336) and 620 in the oxybutynin trial (OER 5 mg, n = 313; OER 10 mg, n = 307). Fewer patients prematurely withdrew from the trial in the TER 4 mg group (12%) than either the OER 5 mg (19%; p = 0.01) or OER 10 mg groups (21%; p = 0.002). More patients in the OER 10 mg group than the TER 4 mg group withdrew because of poor tolerability (13% vs 6%; p = 0.001). After 8 weeks, 70% of patients in the TER 4 mg group perceived an improved bladder condition, compared with 60% in the TER 2 mg group, 59% in the OER 5 mg group and 60% in the OER 10 mg group (all p < 0.01 vs TER 4 mg). Response to therapy was greater in a subgroup of patients whose perception of bladder condition was moderate to severe at baseline (TER 4 mg 77% vs OER 10 mg 65%; p < 0.01). Dry mouth was dose-dependent with both agents, although differences between doses only reached statistical significance in the oxybutynin trial (OER 5 mg vs OER 10 mg; p = 0.05). Patients treated with TER 4 mg reported a significantly lower severity of dry mouth compared with OER 10 mg. In conclusion, the greater efficacy and tolerability of tolterodine ER 4 mg suggests improved clinical effectiveness compared with oxybutynin ER 10 mg." ]

[ "The main objective was to compare the satisfaction levels of antenatal care between healthy pregnant women who received short message service (SMS) via mobile phone for prenatal support, and those who did not. The second objective was to compare the confidence, anxiety levels and also pregnancy outcomes.\n A randomized controlled trial.\n 68 healthy pregnant women who attended the antenatal clinic and delivered at Siriraj Hospital, who met the inclusion criterias between May 2007 and October 2007, were enrolled and randomly allocated into two random groups. The study group received two SMS messages per week from 28 weeks of gestation until giving birth. The other group was pregnant women who did not receive SMS. Both groups had the same antenatal and perinatal care. The satisfaction, confidence and anxiety scores were evaluated using a questionnaire at the postpartum ward. The pregnancy outcomes were also compared in these two groups.\n The satisfaction levels of the women who received prenatal support in SMS messages, were significantly higher than those of who did not receive the messages both in the antenatal period (9.25 vs. 8.00, p < 0.001) and during labor (9.09 vs. 7.90, p = 0.007). In the SMS using group, the confidence level was'higher (8.91 vs. 7.79, p = 0.001) and the anxiety level was lower (2.78 vs. 4.93, p = 0.002) than the control group n the antenatal period, however no diference in pregnancy outcomes were found.\n The present study shows the higher satisfaction level of pregnant women who received SMS via mobile phone during their antenatal service when compared with the general antenatal care group. The study also show the higher confidence level and lower anxiety level in the antenatal period but no difference in pregnancy outcomes." ]

[ "Endobronchial brachytherapy (EBBT) is an established modality for the palliation in advanced non-small cell lung cancer. We compared three different schedules using EBBT with or without external radiation (XRT) in this setting.\n Forty-five patients were randomized to three treatment arms. Arm A received XRT to a dose of 30 Gy/10 fr/2 weeks and two sessions of EBBT 8 Gy each. Arm B received the same XRT and a single session of EBBT 10 Gy at 1 cm. Arm C received only a single fraction of brachytherapy to a dose of 15 Gy at 1 cm without XRT. Symptomatic response rates, duration of symptom palliation, obstruction scores, quality of life outcomes and complications were assessed and compared.\n The overall symptomatic response rates were 91% for dyspnea, 84% for cough, 94% for hemoptysis and 83% for obstructive pneumonia. There was no significant difference between the arms. The median time to symptom relapse was 4-8 months for all symptoms and the median time to symptom progression was 6-11 months. The results were comparable between groups except for hemoptysis, where a shorter palliation was seen in Arm C that achieved statistical significance (P < 0.01). Quality of life showed significant improvement, with maximum benefit in Arm A. Complication rates were low. Only one patient died of fatal hemoptysis.\n EBBT is thus a safe and effective palliative tool in advanced non-small cell lung cancer, either alone or in conjunction with XRT. The difference between the treatment arms were not statistically significant in most categories, but patients treated with XRT and two endobronchial sessions of 8 Gy had the most consistent benefit in terms of all the parameters studied.", "To compare Nd: YAG laser resection with Nd: YAG laser plus brachytherapy and external beam radiotherapy (EBRT) in the palliation of malignant central airway obstruction symptoms due to lung cancer.\n In this prospective non-randomized study we evaluated the effects of Nd:YAG laser photoresection alone vs. Nd:YAG laser resection in combination with brachytherapy and EBRT on cough, dyspnoea, thoracic pain, haemoptysis, body weight loss, atelectasis, postobstructive pneumonia, endoscopic findings, disease-free period and survival rate in lung cancer patients. Only patients with Karnofsky index (KI) < or =50 were included. Sixty-four patients were divided into 2 groups: group I patients ( = 20) were treated only with Nd: YAG laser, and group II patients (n = 44) were treated with Nd: YAG laser followed by brachytherapy and EBRT.\n Group I patients showed statistically significant improvement in all investigated parameters but cough. Group II patients achieved significant improvement in all investigated parameters. Comparative statistical analysis between the 2 groups revealed statistically significant improvement in group II with regard to dyspnoea, haemoptysis, KI and atelectasis. No significant improvement in group II was seen when other investigated parameters were considered. Disease-free period and survival rate were significantly longer in group II (p< or =0.0005).\n The combination of interventional pulmonology procedures with standard modalities is the best option for the treatment of selected lung cancer patients.", "No randomized studies are available on the additional value of endobronchial brachytherapy (EBB) to external irradiation (XRT) regarding palliation of respiratory symptoms (RS). A prospective randomized study was initiated to test the hypothesis that the addition of EBB to XRT provides higher levels of palliation of dyspnea and other RS and improvement of quality of life (QoL) in patients with non-small cell lung cancer (NSCLC) with endobronchial tumour.\n Patients with previously untreated NSCLC, stages I-IIIb, WHO-performance status of 0-3 and with biopsy proven endobronchial tumour in the proximal airways were eligible. EBB consisted of two fractions of 7.5 Gy at 1 cm on day 1 and 8. XRT started at day 2. The XRT dose was 30 Gy (2 weeks) or 60 Gy (6 weeks). The EORTC QLQ-C30 and QLQ-LC13 were assessed before treatment and 2 weeks, 6 weeks, 3, 6 and 12 months after treatment. Re-expansion of collapsed lung was tested by the inspiratory vital capacity (IVC) and CT scan of the chest.\n Ninety-five patients were randomized between arm 1 (XRT alone) (n=48) or arm 2 (XRT+EBB) (n=47). The arms were well balanced regarding pre-treatment characteristics and QoL scores. The compliance for QoL-assessment was >90% at all times. No significant difference between the trial arms was observed with respect to response of dyspnea. However, a beneficial effect of EBB was noted concerning the mean scores of dyspnea over time (P=0.02), which lasted for 3 months. This benefit was only observed among patients with an obstructing tumour of the main bronchus. A higher rate of re-expansion of collapsed lung was observed in arm 2 (57%) compared to arm 1 (35%) (P=0.01). The inspiratory vital capacity (IVC) assessed 2 weeks after radiotherapy improved with 493 cm(3) in arm 2 and decreased 50 cm(3) in arm 1 (P=0.03). No difference was noted regarding the incidence of massive haemoptysis (13 vs. 15%).\n The addition of EBB to XRT in NSCLC is safe and provides higher rates of re-expansion of collapsed lung resulting in a transient lower levels of dyspnea. This beneficial effect was only observed among patients with obstructing tumours in the main bronchus.", "To demonstrate the efficacy of radiochemotherapy (RCT) as the first choice of treatment for advanced unresectable head-and-neck cancer. To prove an expected benefit of simultaneously given chemotherapy, a two-arm randomized study with hyperfractionated accelerated radiochemotherapy (HF-ACC-RCT) vs. hyperfractionated accelerated radiotherapy (HF-ACC-RT) was initiated. The primary endpoint was 1-year survival with local control (SLC).\n Patients with Stage III and IV (UICC) unresectable oro- and hypopharyngeal carcinomas were randomized for HF-ACC-RCT with 2 cycles of 5-FU (600 mg/m(2)/day)/carboplatinum (70 mg/m(2)) on days 1--5 and 29--33 (arm A) or HF-ACC-RT alone (arm B). In both arms, there was a second randomization for testing the effect of prophylactically given G-CSF (263 microg, days 15--19) on mucosal toxicity. Total RT dose in both arms was 69.9 Gy in 38 days, with a concomitant boost regimen (weeks 1--3: 1.8 Gy/day, weeks 4 and 5: b.i.d. RT with 1.8 Gy/1.5 Gy). Between July 1995 and May 1999, 263 patients were randomized (median age 56 years; 96% Stage IV tumors, 4% Stage III tumors).\n This analysis is based on 240 patients: 113 patients with RCT and 127 patients with RT, qualified for protocol and starting treatment. There were 178 oropharyngeal and 62 hypopharyngeal carcinomas. Treatment was tolerable in both arms, with a higher mucosal toxicity after RCT. Restaging showed comparable nonsignificant different CR + PR rates of 92.4% after RCT and 87.9% after RT (p = 0.29). After a median observed time of 22.3 months, l- and 2-year local-regional control (LRC) rates were 69% and 51% after RCT and 58% and 45% after RT (p = 0.14). There was a significantly better 1-year SLC after RCT (58%) compared with RT (44%, p = 0.05). Patients with oropharyngeal carcinomas showed significantly better SLC after RCT (60%) vs. RT (40%, p = 0.01); the smaller group of hypopharyngeal carcinomas had no statistical benefit of RCT (p = 0.84). For both tumor locations, prophylactically given G-CSF was a poor prognostic factor (Cox regression), and resulted in reduced LRC (log-rank test: +/- G-CSF, p = 0.0072).\n With accelerated radiotherapy, the efficiency of simultaneously given chemotherapy may be not as high as expected when compared to standard fractionated RT. Oropharyngeal carcinomas showed better LRC after HF-ACC-RCT vs. HF-ACC-RT; hypopharyngeal carcinomas did not. Prophylactic G-CSF resulted in an unexpected reduced local control and should be given in radiotherapy regimen only with strong hematologic indication.", "Laser debulking and prosthetic stents are useful modalities in the palliative treatment of initial inoperable or recurrent lung cancer. Recently, endobrochial brachytherapy was introduced to extend the duration of palliation and reduce the number of endoscopic treatments. This trial compares Nd-YAG laser alone and associated to high dose rated (HDR)-brachytherapy.\n From 1995 to 1998, 29 consecutive patients, with non-small cell lung cancer (NSCLC) and central airway involvement, were randomized in two groups: group 1 (15 patients) received Nd-YAG laser only; group 2 (14 patients) underwent a combined Nd-YAG laser/ HDR brachytherapy treatment.\n There was no mortality or morbidity related to the treatment. The period free from symptoms was 2.8 months for group 1 and increased to 8.5 months in group 2 (P<0.05). The disease's progression free period grew from 2.2 months of group 1 to 7.5 months of group 2 (P<0.05) and the number of further endoscopic treatment reduced from 15 to 3 (P<0.05).\n The results confirm the potential of brachytherapy to prolong relief from symptoms, lessen disease progression and reduce costs of treatment. A detailed analysis is presented of both groups." ]

[ "Consumption of flavanol-rich dark chocolate (DC) has been shown to decrease blood pressure (BP) and insulin resistance in healthy subjects, suggesting similar benefits in patients with essential hypertension (EH). Therefore, we tested the effect of DC on 24-hour ambulatory BP, flow-mediated dilation (FMD), and oral glucose tolerance tests (OGTTs) in patients with EH. After a 7-day chocolate-free run-in phase, 20 never-treated, grade I patients with EH (10 males; 43.7+/-7.8 years) were randomized to receive either 100 g per day DC (containing 88 mg flavanols) or 90 g per day flavanol-free white chocolate (WC) in an isocaloric manner for 15 days. After a second 7-day chocolate-free period, patients were crossed over to the other treatment. Noninvasive 24-hour ambulatory BP, FMD, OGTT, serum cholesterol, and markers of vascular inflammation were evaluated at the end of each treatment. The homeostasis model assessment of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and insulin sensitivity index (ISI) were calculated from OGTT values. Ambulatory BP decreased after DC (24-hour systolic BP -11.9+/-7.7 mm Hg, P<0.0001; 24-hour diastolic BP -8.5+/-5.0 mm Hg, P<0.0001) but not WC. DC but not WC decreased HOMA-IR (P<0.0001), but it improved QUICKI, ISI, and FMD. DC also decreased serum LDL cholesterol (from 3.4+/-0.5 to 3.0+/-0.6 mmol/L; P<0.05). In summary, DC decreased BP and serum LDL cholesterol, improved FMD, and ameliorated insulin sensitivity in hypertensives. These results suggest that, while balancing total calorie intake, flavanols from cocoa products may provide some cardiovascular benefit if included as part of a healthy diet for patients with EH.", "Consumption of flavanol-containing cocoa products has been shown to lower blood pressure (BP), but the minimum dose required to reduce BP is not known. This study aimed to examine the effect of three different doses of cocoa flavanols (CF) on 24-h mean arterial BP. Twenty four hour ambulatory BP (24-ABP) monitoring was performed in 32 men and 20 postmenopausal women with untreated mild hypertension (seated clinic BP >130/85 and <160/100 mm Hg). Participants were randomized and instructed to consume daily a reconstituted cocoa beverage containing 33, 372, 712 or 1052 mg day(-1) of CF for 6 weeks in a double-blind, parallel comparison. Seated clinic BP and 24-h ABP were measured at 0, 3 and 6 weeks. Seated clinic BP did not change during the study period. There were significant reductions in 24-h systolic (5.3+/-5.1 mm Hg; P=0.001), diastolic (3+/-3.2 mm Hg; P=0.002) and mean arterial BP (3.8+/-3.2 mm Hg; P=0.0004) at the 1052 mg day(-1) CF only. No reduction in BP was seen at any other dose. No evidence of dose-response was seen in this experiment. The highest dose of 1052 mg CF per day was found to significantly lower BP. These results support previous evidence for CF to lower BP, however more research is needed to establish the most effective dose and food matrix.", "Regular intake of cocoa-containing foods is linked to lower cardiovascular mortality in observational studies. Short-term interventions of at most 2 weeks indicate that high doses of cocoa can improve endothelial function and reduce blood pressure (BP) due to the action of the cocoa polyphenols, but the clinical effect of low habitual cocoa intake on BP and the underlying BP-lowering mechanisms are unclear.\n To determine effects of low doses of polyphenol-rich dark chocolate on BP.\n Randomized, controlled, investigator-blinded, parallel-group trial involving 44 adults aged 56 through 73 years (24 women, 20 men) with untreated upper-range prehypertension or stage 1 hypertension without concomitant risk factors. The trial was conducted at a primary care clinic in Germany between January 2005 and December 2006.\n Participants were randomly assigned to receive for 18 weeks either 6.3 g (30 kcal) per day of dark chocolate containing 30 mg of polyphenols or matching polyphenol-free white chocolate.\n Primary outcome measure was the change in BP after 18 weeks. Secondary outcome measures were changes in plasma markers of vasodilative nitric oxide (S-nitrosoglutathione) and oxidative stress (8-isoprostane), and bioavailability of cocoa polyphenols.\n From baseline to 18 weeks, dark chocolate intake reduced mean (SD) systolic BP by -2.9 (1.6) mm Hg (P < .001) and diastolic BP by -1.9 (1.0) mm Hg (P < .001) without changes in body weight, plasma levels of lipids, glucose, and 8-isoprostane. Hypertension prevalence declined from 86% to 68%. The BP decrease was accompanied by a sustained increase of S-nitrosoglutathione by 0.23 (0.12) nmol/L (P < .001), and a dark chocolate dose resulted in the appearance of cocoa phenols in plasma. White chocolate intake caused no changes in BP or plasma biomarkers.\n Data in this relatively small sample of otherwise healthy individuals with above-optimal BP indicate that inclusion of small amounts of polyphenol-rich dark chocolate as part of a usual diet efficiently reduced BP and improved formation of vasodilative nitric oxide.\n clinicaltrials.gov Identifier: NCT00421499.", "Flavanol-rich cocoa products have been reported to lower blood pressure. It has been suggested that theobromine is partially responsible for this effect. We tested whether consumption of flavanol-rich cocoa drinks with natural or added theobromine could lower peripheral and central blood pressure. In a double-blind, placebo-controlled 3-period crossover trial we assigned 42 healthy individuals (age 62±4.5 years; 32 men) with office blood pressure of 130 to 159 mm Hg/85 to 99 mm Hg and low added cardiovascular risk to a random treatment sequence of dairy drinks containing placebo, flavanol-rich cocoa with natural dose consisting of 106 mg of theobromine, or theobromine-enriched flavanol-rich cocoa with 979 mg of theobromine. Treatment duration was 3 weeks with a 2-week washout. The primary outcome was the difference in 24-hour ambulatory systolic blood pressure between placebo and active treatment after 3 weeks. The difference in central systolic blood pressure between placebo and active treatment was a secondary outcome. Treatment with theobromine-enriched cocoa resulted in a mean±SE of 3.2±1.1 mm Hg higher 24-hour ambulatory systolic blood pressure compared with placebo (P<0.01). In contrast, 2 hours after theobromine-enriched cocoa, laboratory peripheral systolic blood pressure was not different from placebo, whereas central systolic blood pressure was 4.3±1.4 mm Hg lower (P=0.001). Natural dose theobromine cocoa did not significantly change either 24-hour ambulatory or central systolic blood pressure compared with placebo. In conclusion, theobromine-enriched cocoa significantly increased 24-hour ambulatory systolic blood pressure while lowering central systolic blood pressure.", "Essential hypertension is characterized by reciprocal relations between endothelial dysfunction and insulin resistance. Cocoa flavanols stimulate production of the vasodilator nitric oxide from vascular endothelium.\n The objective was to test the hypothesis that consumption of cocoa may simultaneously lower blood pressure, improve endothelial dysfunction, and ameliorate insulin resistance in subjects with essential hypertension.\n We conducted a randomized, placebo-controlled, double-blind, crossover trial of a flavanol-rich cocoa drink (150 mL twice a day, approximately 900 mg flavanols/d) in individuals with essential hypertension (n = 20). Antihypertensive medications were discontinued before study enrollment. After a 7-d cocoa-free run-in period, cocoa or flavanol-poor placebo (approximately 28 mg flavanols/d) treatment for 2 wk was followed by a 1-wk washout and then crossover to the other treatment arm. Blood pressure was measured thrice weekly. At baseline and after each treatment period, we assessed insulin sensitivity (hyperinsulinemic-isoglycemic glucose clamp) and insulin-stimulated changes in brachial artery diameter and forearm skeletal muscle capillary recruitment (Doppler ultrasound with or without microbubble contrast).\n Cocoa treatment for 2 wk increased insulin-stimulated changes in brachial artery diameter when compared with placebo [median percentage increase from baseline (25th-75th percentile): 8.3 (4.2-11.3) compared with 5.9 (-0.3 to 9.6); P < 0.04]. Nevertheless, cocoa treatment did not significantly reduce blood pressure or improve insulin resistance and had no significant effects on skeletal muscle capillary recruitment, circulating plasma concentrations of adipocytokines, or endothelial adhesion molecules.\n Daily consumption of flavanol-rich cocoa for 2 wk is not sufficient to reduce blood pressure or improve insulin resistance in human subjects with essential hypertension. This trial was registered at clinicaltrials.gov as NCT00099476.", "To assess the effects of the oral intake of flavonoid-rich dark chocolate on coronary circulation, we measured coronary flow velocity reserve (CFVR) by noninvasive transthoracic Doppler echocardiography (TTDE) in healthy adult subjects.\n The study was a randomized, single-blind design conducted for 2 weeks in 39 healthy men (mean age 29.7+/-3.9 years, range 23-40 years). Subjects were randomly assigned a daily intake of either flavonoid-rich dark chocolate (Meiji Black Chocolate 45 g, Meiji Seika kaisya Ltd, including cacao polyphenol 550 mg/day, 200 kcal) or non-flavonoid white chocolate (Meiji White Chocolate 35 g, Meiji Seika kaisya Ltd, including cacao polyphenol 0 mg/day, 140 kcal) as a control. CFVR was recorded by TTDE, and assessed before and after 2 weeks of intake. At the same time, we also assessed serum asymmetric dimethylarginine, 8-isoprostanes, and malondialdehyde-modified low-density lipoprotein (MDA-LDL) as markers of oxidative stress.\n Flavonoid-rich dark chocolate consumption significantly improved CFVR (3.38+/-0.49 before intake, 4.28+/-0.85 after intake; p<0.01), whereas non-flavonoid white chocolate consumption did not (3.28+/-0.49 before intake, 3.16+/-0.49 after intake; p=0.44). All predictor variables were used as dependent variables in a multiple regression model of the incremental change in CFVR after 2 weeks of chocolate intake. Intake of dark (but not white) chocolate, MDA-LDL, triglyceride (TG) and heart rate (HR) significantly influenced the change of CFVR after 2 weeks of intake (p<0.01) according to the multiple regression formula: Y=1.01X(1)-0.005X(2)-0.003X(3)-0.017X4 (Y=change in CFVR after 2 weeks of chocolate intake, X1=intake of dark (but not white) chocolate, X2=MDA-LDL, X3=TG, X4=HR).\n Flavonoid-rich dark chocolate intake significantly improved coronary circulation in healthy adults, independent of changes in oxidative stress parameters, blood pressure and lipid profile, whereas non-flavonoid white chocolate had no such effects.", "Flavanol-rich chocolate and lycopene-rich tomato extract have attracted interest as potential alternative treatment options for hypertension, a known risk factor for cardiovascular morbidity and mortality. Treatment of prehypertension (SBP 120-139/DBP 80-89 mmHg) may forestall progression to hypertension. However, there has been only limited research into non-pharmacological treatment options for prehypertension. We investigated the effect of dark chocolate or tomato extract on blood pressure, and their acceptability as an ongoing treatment option in a prehypertensive population.\n Our trial consisted of two phases: a randomised controlled three-group-parallel trial over 12 weeks (phase 1) followed by a crossover of the two active treatment arms over an additional 12-week period (phase 2). Group 1 received a 50 g daily dose of dark chocolate with 70% cocoa containing 750 mg polyphenols, group 2 were allocated one tomato extract capsule containing 15 mg lycopene per day, and group 3 received one placebo capsule daily over 8 weeks followed by a 4-week washout period. In phase 2 the active treatment groups were crossed over to receive the alternative treatment. Median blood pressure, weight, and abdominal circumference were measured 4-weekly, and other characteristics including physical activity, general health, energy, mood, and acceptability of treatment were assessed by questionnaire at 0, 8 and 20 weeks. We analysed changes over time using a linear mixed model, and one time point differences using Kruskal-Wallis, Fisher's-Exact, or t-tests.\n Thirty-six prehypertensive healthy adult volunteers completed the 6-month trial. Blood pressure changes over time within groups and between groups were not significant and independent of treatment. Weight and other characteristics did not change significantly during the trial. However, a marked difference in acceptability between the two treatment forms (chocolate or capsule) was revealed (p < 0.0001). Half of the participants allocated to the chocolate treatment found it hard to eat 50 g of dark chocolate every day and 20% considered it an unacceptable long-term treatment option, whereas all participants found it easy and acceptable to take a capsule each day for blood pressure.\n Our study did not find a blood pressure lowering effect of dark chocolate or tomato extract in a prehypertensive population. Practicability of chocolate as a long-term treatment option may be limited.\n http://www.anzctr.org.au Identifier: ACTRN12609000047291.", "Impaired endothelial function in obesity may reduce blood flow to sites of metabolism, contributing to impaired fat oxidation and insulin resistance. This study investigated the effects of cocoa flavanols and regular exercise, interventions known to improve endothelial function, on cardiometabolic function and body composition in obese individuals.\n Overweight and obese adults were randomly assigned to high-flavanol cocoa (HF, 902 mg flavanols), HF and exercise, low-flavanol cocoa (LF, 36 mg flavanols), or LF and exercise for 12 weeks (exercise duration was 3 x 45 min per week at 75% of age-predicted maximum heart rate). Body composition was assessed by dual-energy X-ray absorptiometry at 0 and 12 weeks. Brachial artery flow-mediated dilatation (FMD), supine blood pressure (BP) and fasting plasma insulin, and glucose levels were assessed at 0, 6 and 12 weeks, respectively. Insulin sensitivity/resistance was determined using the modified homeostasis model assessment of insulin resistance (HOMA2).\n A total of 49 subjects (M=18; F=31) completed the intervention. Baseline averages were as follows: body mass index=33.5 kg/m(2); BP=123/76 mm Hg; HOMA2=2.4; FMD=4.3%; rate of fat oxidation during exercise=0.34 g min(-1); abdominal fat=45.7% of total abdominal mass. Compared to LF, HF increased FMD acutely (2 h post-dose) by 2.4% (P<0.01) and chronically (over 12 weeks; P<0.01) by 1.6% and reduced insulin resistance by 0.31% (P<0.05), diastolic BP by 1.6 mm Hg and mean arterial BP by 1.2 mm Hg (P<0.05), independent of exercise. Regular exercise increased fat oxidation during exercise by 0.10 g min(-1) (P<0.01) and reduced abdominal fat by 0.92% (P<0.05).\n Although HF consumption was shown to improve endothelial function, it did not enhance the effects of exercise on body fat and fat metabolism in obese subjects. However, it may be useful for reducing cardiometabolic risk factors in this population.", "In recent years, there has been increased interest in the potential health-related benefits of antioxidant- and phytochemical-rich dark chocolate and cocoa.\n The objective of the study was to examine the short-term (6 wk) effects of dark chocolate and cocoa on variables associated with neuropsychological functioning and cardiovascular health in healthy older adults.\n A double-blind, placebo-controlled, fixed-dose, parallel-group clinical trial was used. Participants (n = 101) were randomly assigned to receive a 37-g dark chocolate bar and 8 ounces (237 mL) of an artificially sweetened cocoa beverage or similar placebo products each day for 6 wk.\n No significant group (dark chocolate and cocoa or placebo)-by-trial (baseline, midpoint, and end-of-treatment assessments) interactions were found for the neuropsychological, hematological, or blood pressure variables examined. In contrast, the midpoint and end-of-treatment mean pulse rate assessments in the dark chocolate and cocoa group were significantly higher than those at baseline and significantly higher than the midpoint and end-of-treatment rates in the control group. Results of a follow-up questionnaire item on the treatment products that participants believed they had consumed during the trial showed that more than half of the participants in both groups correctly identified the products that they had ingested during the experiment.\n This investigation failed to support the predicted beneficial effects of short-term dark chocolate and cocoa consumption on any of the neuropsychological or cardiovascular health-related variables included in this research. Consumption of dark chocolate and cocoa was, however, associated with significantly higher pulse rates at 3- and 6-wk treatment assessments.", "Dark chocolate derived from the plant (Theobroma cacao) is a rich source of flavonoids. Cardioprotective effects including antioxidant properties, inhibition of platelet activity, and activation of endothelial nitric oxide synthase have been ascribed to the cocoa flavonoids.\n To investigate the effects of flavonoid-rich dark chocolate on endothelial function, measures of oxidative stress, blood lipids, and blood pressure in healthy adult subjects.\n The study was a randomized, double-blind, placebo-controlled design conducted over a 2 week period in 21 healthy adult subjects. Subjects were randomly assigned to daily intake of high-flavonoid (213 mg procyanidins, 46 mg epicatechin) or low-flavonoid dark chocolate bars (46 g, 1.6 oz).\n High-flavonoid chocolate consumption improved endothelium-dependent flow-mediated dilation (FMD) of the brachial artery (mean change = 1.3 +/- 0.7%) as compared to low-flavonoid chocolate consumption (mean change = -0.96 +/- 0.5%) (p = 0.024). No significant differences were noted in the resistance to LDL oxidation, total antioxidant capacity, 8-isoprostanes, blood pressure, lipid parameters, body weight or body mass index (BMI) between the two groups. Plasma epicatechin concentrations were markedly increased at 2 weeks in the high-flavonoid group (204.4 +/- 18.5 nmol/L, p < or = 0.001) but not in the low-flavonoid group (17.5 +/- 9 nmol/L, p = 0.99).\n Flavonoid-rich dark chocolate improves endothelial function and is associated with an increase in plasma epicatechin concentrations in healthy adults. No changes in oxidative stress measures, lipid profiles, blood pressure, body weight or BMI were seen.", "The consumption of a diet rich in certain flavonoids, including the flavanol sub-class, has been associated with a reduced risk for vascular disease. We evaluated the effects of the regular consumption (14 d) of a flavanol-containing milk chocolate (FCMC) or cocoa butter chocolate (CBC) on variables related to vascular disease risk, oxidative stress and physical activity. Twenty-eight free-living, young (18-20 years old) male soccer players consumed daily 105 g of FCMC (168 mg of flavanols) or CBC (< 5 mg of flavanols), as part of their normal diet. The consumption of FCMC was significantly associated with a decrease in diastolic blood pressure (- 5 mm Hg), mean blood pressure (- 5 mm Hg), plasma cholesterol (-11%), LDL-cholesterol (-15%), malondialdehyde (- 12%), urate (- 11%) and lactate dehydrogenase (LDH) activity (- 11%), and an increase in vitamin E/cholesterol (+ 12%). No relevant changes in these variables were associated with CBC consumption. No changes in the plasma levels of (-)-epicatechin were observed following analysis of fasting blood samples. In conclusion, FCMC consumption was associated with changes in several variables often associated with cardiovascular health and oxidant stress. The presence of significant quantities of flavanols in FCMC is likely to have been one of the contributing factors to these results.", "Epidemiologic studies have suggested that flavonoid intake plays a critical role in the prevention of coronary heart disease. Because atherosclerosis is considered a low-grade inflammatory disease, some feeding trials have analyzed the effects of cocoa (an important source of flavonoids) on inflammatory biomarkers, but the results have been controversial.\n The objective was to evaluate the effects of chronic cocoa consumption on cellular and serum biomarkers related to atherosclerosis in high-risk patients.\n Forty-two high-risk volunteers (19 men and 23 women; mean +/- SD age: 69.7 +/- 11.5 y) were included in a randomized crossover feeding trial. All subjects received 40 g cocoa powder with 500 mL skim milk/d (C+M) or only 500 mL skim milk/d (M) for 4 wk. Before and after each intervention period, cellular and serum inflammatory biomarkers related to atherosclerosis were evaluated.\n Adherence to the dietary protocol was excellent. No significant changes in the expression of adhesion molecules on T lymphocyte surfaces were found between the C+M and M groups. However, in monocytes, the expression of VLA-4, CD40, and CD36 was significantly lower (P = 0.005, 0.028, and 0.001, respectively) after C+M intake than after M intake. In addition, serum concentrations of the soluble endothelium-derived adhesion molecules P-selectin and intercellular adhesion molecule-1 were significantly lower (both P = 0.007) after C+M intake than after M intake.\n These results suggest that the intake of cocoa polyphenols may modulate inflammatory mediators in patients at high risk of cardiovascular disease. These antiinflammatory effects may contribute to the overall benefits of cocoa consumption against atherosclerosis. This trial was registered in the Current Controlled Trials at London, International Standard Randomized Controlled Trial Number, at controlled-trials.com as ISRCTN75176807.", "Flavonoids may be partly responsible for some health benefits, including antiinflammatory action and a decreased tendency for the blood to clot. An acute dose of flavanols and oligomeric procyanidins from cocoa powder inhibits platelet activation and function over 6 h in humans.\n This study sought to evaluate whether 28 d of supplementation with cocoa flavanols and related procyanidin oligomers would modulate human platelet reactivity and primary hemostasis and reduce oxidative markers in vivo.\n Thirty-two healthy subjects were assigned to consume active (234 mg cocoa flavanols and procyanidins/d) or placebo (< or = 6 mg cocoa flavanols and procyanidins/d) tablets in a blinded parallel-designed study. Platelet function was determined by measuring platelet aggregation, ATP release, and expression of activation-dependent platelet antigens by using flow cytometry. Plasma was analyzed for oxidation markers and antioxidant status.\n Plasma concentrations of epicatechin and catechin in the active group increased by 81% and 28%, respectively, during the intervention period. The active group had significantly lower P selectin expression and significantly lower ADP-induced aggregation and collagen-induced aggregation than did the placebo group. Plasma ascorbic acid concentrations were significantly higher in the active than in the placebo group (P < 0.05), whereas plasma oxidation markers and antioxidant status did not change in either group.\n Cocoa flavanol and procyanidin supplementation for 28 d significantly increased plasma epicatechin and catechin concentrations and significantly decreased platelet function. These data support the results of acute studies that used higher doses of cocoa flavanols and procyanidins.", "Flavanols from chocolate appear to increase nitric oxide bioavailability, protect vascular endothelium, and decrease cardiovascular disease (CVD) risk factors. We sought to test the effect of flavanol-rich dark chocolate (FRDC) on endothelial function, insulin sensitivity, beta-cell function, and blood pressure (BP) in hypertensive patients with impaired glucose tolerance (IGT). After a run-in phase, 19 hypertensives with IGT (11 males, 8 females; 44.8 +/- 8.0 y) were randomized to receive isocalorically either FRDC or flavanol-free white chocolate (FFWC) at 100 g/d for 15 d. After a wash-out period, patients were switched to the other treatment. Clinical and 24-h ambulatory BP was determined by sphygmometry and oscillometry, respectively, flow-mediated dilation (FMD), oral glucose tolerance test, serum cholesterol and C-reactive protein, and plasma homocysteine were evaluated after each treatment phase. FRDC but not FFWC ingestion decreased insulin resistance (homeostasis model assessment of insulin resistance; P < 0.0001) and increased insulin sensitivity (quantitative insulin sensitivity check index, insulin sensitivity index (ISI), ISI(0); P < 0.05) and beta-cell function (corrected insulin response CIR(120); P = 0.035). Systolic (S) and diastolic (D) BP decreased (P < 0.0001) after FRDC (SBP, -3.82 +/- 2.40 mm Hg; DBP, -3.92 +/- 1.98 mm Hg; 24-h SBP, -4.52 +/- 3.94 mm Hg; 24-h DBP, -4.17 +/- 3.29 mm Hg) but not after FFWC. Further, FRDC increased FMD (P < 0.0001) and decreased total cholesterol (-6.5%; P < 0.0001), and LDL cholesterol (-7.5%; P < 0.0001). Changes in insulin sensitivity (Delta ISI - Delta FMD: r = 0.510, P = 0.001; Delta QUICKI - Delta FMD: r = 0.502, P = 0.001) and beta-cell function (Delta CIR(120) - Delta FMD: r = 0.400, P = 0.012) were directly correlated with increases in FMD and inversely correlated with decreases in BP (Delta ISI - Delta 24-h SBP: r = -0.368, P = 0.022; Delta ISI - Delta 24-h DBP r = -0.384, P = 0.017). Thus, FRDC ameliorated insulin sensitivity and beta-cell function, decreased BP, and increased FMD in IGT hypertensive patients. These findings suggest flavanol-rich, low-energy cocoa food products may have a positive impact on CVD risk factors.", "In patients with coronary artery disease (CAD) medically managed according to currently accepted guidelines, we tested whether a 1-month dietary intervention with flavanol-containing cocoa leads to an improvement of endothelial dysfunction and whether this is associated with an enhanced number and function of circulating angiogenic cells (CACs).\n Dietary flavanols can improve endothelial dysfunction. The CACs, also termed endothelial progenitor cells, are critical for vascular repair and maintenance of endothelial function.\n In a randomized, controlled, double-masked, cross-over trial, 16 CAD patients (64+/-3 years of age) received a dietary high-flavanol intervention (HiFI [375 mg]) and a macronutrient- and micronutrient-matched low-flavanol intervention (LoFI [9 mg]) twice daily in random order over 30 days.\n Endothelium-dependent vasomotor function, as measured by flow-mediated vasodilation of the brachial artery, improved by 47% in the HiFI period compared with the LoFI period. After HiFI, the number of CD34+/KDR+-CACs, as measured by flow cytometry, increased 2.2-fold as compared with after LoFI. The CAC functions, as measured by the capacity to survive, differentiate, proliferate, and to migrate were not different between the groups. The HiFI led to a decrease in systolic blood pressure (mean change over LoFI: -4.2+/-2.7 mm Hg), and increase in plasma nitrite level (mean change over LoFI: 74+/-32 nM). Applying a mixed-effects linear regression model, the results demonstrated a significant increase in flow-mediated vasodilation and a decrease in systolic blood pressure with increasing levels of CD34+/KDR+-CACs.\n Sustained improvements in endothelial dysfunction by regular dietary intake of flavanols are associated with mobilization of functional CACs.

Participants were randomly assigned to a treatment sequence: sugar-free cocoa beverage, sugar-sweetened cocoa beverage, and sugar-sweetened cocoa-free placebo. Treatments were administered daily for 6 weeks, with a 4-week washout period.\n Cocoa ingestion improved EF measured as flow-mediated dilation (FMD) compared to placebo (sugar-free cocoa: change, 2.4% [95% CI, 1.5 to 3.2] vs. -0.8% [95% CI, -1.9 to 0.3]; difference, 3.2% [95% CI, 1.8 to 4.6]; p<0.001 and sugar-sweetened cocoa: change, 1.5% [95% CI, 0.6 to 2.4] vs. -0.8% [95% CI, -1.9 to 0.3]; difference, 2.3% [95% CI, 0.9 to 3.7]; p=0.002). The magnitude of improvement in FMD after consumption of sugar-free versus sugar-sweetened cocoa was greater, but not significantly.

After 3 mo, systolic blood pressure remained significantly lower. CSC lowered serum amyloid-alpha by 42% and lowered malondialdehyde by 11.9%. In men, there were 10- and 9-mg/dL reductions in total and low-density lipoprotein (LDL) cholesterol, respectively. In all subjects with a baseline LDL cholesterol level >99 mg/dL, there was 9 mg/dL lowering of total and LDL cholesterol.

[ "Oral anticoagulation therapy reduces risk of vascular events in patients with atrial fibrillation. However, long-term monitoring is necessary and many patients cannot achieve optimum anticoagulation. We assessed whether clopidogrel plus aspirin was non-inferior to oral anticoagulation therapy for prevention of vascular events.\n Patients were enrolled if they had atrial fibrillation plus one or more risk factor for stroke, and were randomly allocated to receive oral anticoagulation therapy (target international normalised ratio of 2.0-3.0; n=3371) or clopidogrel (75 mg per day) plus aspirin (75-100 mg per day recommended; n=3335). Outcome events were adjudicated by a blinded committee. Primary outcome was first occurrence of stroke, non-CNS systemic embolus, myocardial infarction, or vascular death. Analyses were by intention-to-treat. This study is registered with ClinicalTrials.gov, number NCT00243178.\n The study was stopped early because of clear evidence of superiority of oral anticoagulation therapy. There were 165 primary events in patients on oral anticoagulation therapy (annual risk 3.93%) and 234 in those on clopidogrel plus aspirin (annual risk 5.60%; relative risk 1.44 (1.18-1.76; p=0.0003). Patients on oral anticoagulation therapy who were already receiving this treatment at study entry had a trend towards a greater reduction in vascular events (relative risk 1.50, 95% CI 1.19-1.89) and a significantly (p=0.03 for interaction) lower risk of major bleeding with oral anticoagulation therapy (1.30; 0.94-1.79) than patients not on this treatment at study entry (1.27, 0.85-1.89 and 0.59, 0.32-1.08, respectively).\n Oral anticoagulation therapy is superior to clopidogrel plus aspirin for prevention of vascular events in patients with atrial fibrillation at high risk of stroke, especially in those already taking oral anticoagulation therapy.", "This trial evaluated the efficacy and safety of the combination of antiplatelet and moderate-intensity anticoagulation therapy in patients with atrial fibrillation associated with recognized risk factors or mitral stenosis.\n Warfarin was more effective than aspirin in preventing stroke in these patients; combined therapy with low anticoagulant intensity was ineffective.

The intermediate-risk group included patients with risk factors or age >60 years: 242 received the cyclooxygenase inhibitor triflusal, 237 received acenocumarol, and 235 received a combination of both. The high-risk group included patients with prior embolism or mitral stenosis: 259 received anticoagulants and 236 received the combined therapy. Median follow-up was 2.76 years. Primary outcome was a composite of vascular death and nonfatal stroke or systemic embolism.\n Primary outcome was lower in the combined therapy than in the anticoagulant arm in both the intermediate- (hazard ratio [HR] 0.33 [95% confidence interval (CI)0.12 to 0.91]; p = 0.02) and the high-risk group (HR 0.51 [95% CI 0.27 to 0.96]; p = 0.03). Primary outcome plus severe bleeding was lower with combined therapy in the intermediate-risk group.

The patients were followed up 1 day, and 1, 6, 12, and 18 months after the operation to undergo color Doppler ultrasonography, and examinations of blood routine, bleeding time, coagulation time, and ankle-brachial Index. The primary endpoint events included major bleeding rate, and composite rate of restenosis and reocclusion. The secondary endpoint events included cardiovascular events, death, and adverse drug reaction.\n There were no significant differences in the baseline data between these two groups.

[ "To determine the impact of different flush and reperfusion techniques on postreperfusion syndrome (PRS) and postoperative graft function, 100 transplants were randomly assigned into four groups as follows: group 1 (n=31), portal vein flush, no vena caval venting; group 2 (n=21), hepatic arterial flush, no vena caval venting; group 3 (n=29), portal vein flush with vena caval venting; and group 4 (n=19), hepatic artery flush with vena caval venting. Donor and recipient characteristics were similar. Extensive intraoperative and postoperative monitoring was performed and measurements were documented immediately before reperfusion and at 1, 5, 15, and 30 min after reperfusion. PRS was defined by three criteria: mean arterial pressure (MAP) <60 mmHg at 1 min after reperfusion, MAP <60 mmHg at 5 min after reperfusion, and a decrease of 30% or more for the MAP percent area under the curve during the initial 5 min after reperfusion (%AUC). Using these definitions, the overall incidence of PRS was 21%, 8%, and 43%, respectively. Group 1 was the most hemodynamically stable; the incidence of PRS in group 1 was 2/31 (7%) at 1 min and 8/31 (25%) using %AUC criteria compared with 7/21 (33%) at 1 min and 12/21 (57%) using %AUC criteria for group 2 (P<0.05). The patients in groups 3 and 4 (vena caval venting) demonstrated smaller percentage increases in serum potassium levels (as determined by %AUC; 4.3+/-6.8 and 0.3+/-5.4, vs. 15.1+/-8.1 for group 1 and 22.9+/-8.2 for group 2). The difference between group 4 and group 2 was statistically significant (P<0.05). The increases in serum potassium did not translate into increased cardiac or hemodynamic instability. Combining all data obtained over the first 30 min after reperfusion, there was no statistically significant difference in hemodynamic or biochemical changes noted among the four groups. Postoperative liver function was similar among the four groups. We conclude that portal vein flush without vena caval venting provided a lower incidence of PRS than any other technique. Vena caval venting decreased the release of potassium into the circulation. Postoperative graft function was not significantly affected by flush and reperfusion techniques.", "Although sequential portal and arterial revascularization (SPAr) is the most common method of graft reperfusion at liver transplantation (OLT), contemporaneous portal and hepatic artery revascularization (CPAr) has been used to reduce arterial ischemia to the bile ducts. The aim of this study was to prospectively compare SPAr (group 1; n=19) versus CPAr (group 2; n=21) among 40 consecutive OLT from heart-beating donors. There were no differences in the demographics characteristics, Model for End-stage Liver Disease scores, indication for OLT and donor parameters between the groups. OLT was performed using the piggyback technique. The biliary anastomosis was performed in all cases by a duct-to-duct technique with a T-tube in 32% versus 29% of cases without a T tube (P=.83). In the CPAr group, the liver was reperfused simultaneously via the portal vein and hepatic artery. CPAr showed a longer warm ischemia (66 ± 8 vs 37 ± 7 minutes; P<.001), while SPAr had a longer arterial ischemia 103 ± 42 vs 66 ± 8 minutes (P=.0004). Recovery of graft function was similar. There was no primary nonfunction and delayed graft function occurred among 10% versus 9%. Liver function tests were similar between the two groups up to 90 days case of follow-up- One-year graft and patient survivals were, respectively, 89% and 95% versus 94% and 100% (P=.29). At a median follow-up of 13 ± 6 versus 14 ± 7 months, biliary complications included anastomotic stenoses in 15% versus 19% (P=.78) and intrahepatic non-anastomotic biliary strictures in 26% versus none (P=.01) for SPAr and CPAr, respectively. CPAr was safe and feasible, reducing the incidence of intrahepatic biliary strictures by decreasing the duration of arterial ischemia to the intrahepatic bile ducts.\n Copyright © 2011 Elsevier Inc.

In instances of large blood loss, the transfusion of whole blood rather than the combination of RBCs and FFP is rational and may be preferred.\n In a controlled, prospective, randomized study of 33 patients undergoing orthotopic liver transplantation, the effectiveness of component therapy (RBCs and FFP) was compared with the use of whole blood. Coagulation tests (prothrombin time and activated partial thromboplastin time), clotting factor levels (FV, FVIII, fibrinogen), platelet counts, the number of donor exposures, and the total volume of blood transfused for the whole-blood group and the component-therapy group were compared at designated times before surgery, during surgery, and 24 hours after surgery.\n There was a significant difference (p=0.015) in the median number of donor exposures for RBCs and FFP, with fewer occurring in the whole-blood group (n=14.5) compared with the component group (n=25). There was no significant difference between groups in coagulation profiles during any of the phases of surgery except for a mild decrease in fibrinogen levels in the whole-blood group at the conclusion of surgery. There were no differences between the groups in the median volume of blood component replacement, the median age of blood components, the patients' Hct or the number of RBC-containing components transfused.\n Whole blood, when compared with component therapy, is associated with fewer donor exposures yet provided equally effective replacement therapy for blood loss in liver transplantation patients.", "End-stage liver disease (ESLD) is associated with a low systemic vascular resistance due to peripheral vasodilatation. This phenomenon is aggravated by general anesthesia (GA) administered during liver transplantation, resulting in precipitous decreases in blood pressure. The excessive amounts (>3 mL/1 mL blood loss) of IV fluid administered to maintain hemodynamic stability during surgery promotes a fluid shift in the lung, which may lead to hypoxia in the immediate postoperative period. This pathophysiologic state may necessitate endotracheal reintubation and mechanical ventilation of the lungs, thus exposing the patient to a risk for morbidities related to laryngoscopy and endotracheal intubation, including deleterious cardiovascular responses to laryngoscopy, endotracheal damage due to laryngoscopic instrumentation, alteration in pulmonary mechanics secondary to controlled mechanical ventilation of the lungs, and delayed recovery associated with the sedation needed to perform these maneuvers.\n The aim of this study was to determine whether the use of a vasopressor to antagonize the vasodilatory effect of GA would reduce the amount of IV fluids administered during liver transplantation, and whether the subsequent amelioration of fluid shift in the postoperative period would reduce the need for ventilatory support and endotracheal reintubation.\n This prospective, randomized, double-blind, placebo-controlled study was conducted at the University of Medicine and Dentistry of New Jersey-New Jersey Medical School, Newark, New Jersey. Patients aged > or =18 years scheduled to undergo orthotopic liver transplantation for ESLD were enrolled. The effect of use of an adjuvant vasopressor, together with controlled fluid administration (ie, the volume of IV fluid needed to maintain hemodynamic parameters at > or =80% of preoperative levels) (vasopressor group), was compared with that of fluid administration only (placebo group). We determined various postoperative outcome measures, primarily the amount of fluid administered and the need for endotracheal reintubation.\n Sixty-five patients were enrolled (44 men, 21 women; vasopressor, 33 patients; placebo, 32 patients). Sex distribution showed 19 men and 14 women in the vasopressor group and 25 men and 7 women in the placebo group (both, P < 0.05). The 2 treatment groups were statistically similar with regard to the rest of the baseline demographic and clinical characteristics and duration of surgery. The vasopressor group had a significantly lower prevalence of endotracheal reintubation compared with the placebo group (RR, 1:6; P < 0.05). The other postoperative parameters were statistically similar between the 2 groups.\n In this study of adults undergoing orthotopic liver transplantation for ESLD, use of an adjuvant vasopressor, together with controlled fluid administration, to maintain a stable hemodynamic status during GA reduced the need for endotracheal reintubation and its associated morbidities in the postoperative period compared with placebo.", "Although the low central venous pressure (LCVP) technique is used to decrease blood loss during liver resection, its efficacy and safety during transplant procedures are still debatable. Our study aimed to assess the effects of this technique and its clinical safety for recipients undergoing liver transplantation.\n Eighty-six adult patients were randomly divided into a LCVP group and a control group. In the LCVP group, CVP was maintained below 5 mmHg or 40% lower than baseline during the preanhepatic phase by limiting infusion volume, manipulating the patient's posture, and administration of somatostatin and nitroglycerine. Recipients in the control group received standard care. Hemodynamics, blood loss, liver function, and renal function of the two groups were compared perioperatively.\n A lower CVP was maintained in the LCVP group during the preanhepatic phase, resulting in a significant decrease in blood loss (1922 +/- 1429 vs. 3111 +/- 1833 ml, P < 0.05) and transfusion volume (1200 +/- 800 vs. 2400 +/- 1200 ml, P < 0.05) intraoperatively. Compared with the control group, the LCVP group had a significantly lower mean arterial pressure at 2 h after the start of the operation (74 +/- 11 vs. 84 +/- 14 mmHg, P < 0.05), a lower lactate value at the end of the operation (5.9 +/- 3.0 vs. 7.2 +/- 3.0 mmol/l, P < 0.05), and a better preservation of liver function after the declamping of the portal vein. There were no significant differences in perioperative renal function and postoperative complications between the groups.\n The LCVP technique during the preanhepatic phase reduced intraoperative blood loss, protected liver function, and had no detrimental effects on renal function in LT.", "Virus inactivation of pooled fresh-frozen plasma (FFP) by the solvent/detergent (SD) method results in a loss of approximately 20 percent of factor VIII. This study aimed to assess the efficacy of SD-treated plasma in correcting the coagulopathy associated with liver disease and liver transplantation.\n Forty-nine patients with coagulation deficits due to liver disease, who required FFP for invasive procedures or liver transplantation, were randomly assigned to receive either FFP or SD-treated plasma. Patients were assessed for side effects, correction of coagulopathy over 24 hours, and seroconversion for viral markers 6 to 18 months after treatment.\n In the liver disease group, equal correction of clotting factors and partial thromboplastin time was seen with FFP and SD-treated plasma, with a similar return to baseline values over 24 hours. There was greater correction of the International Normalised Ratio in patients receiving SD-treated plasma (p = 0.037), but this patient group had higher baseline values than recipients of FFP (p = 0.024). Liver transplant patients also showed equivalent correction of coagulopathy with the same dose of FFP and SD-treated plasma. The use of other blood components during transplantation was identical in the two treatment groups. No seroconversions were seen for HIV or hepatitis B or C virus. One patient who had received FFP seroconverted for human parvovirus B19. Apparent seroconversion for hepatitis A virus seen at 9 to 13 months in four other patients was probably due to detection of passively transferred antibodies, as later testing of these patients gave negative results. Minor side effects were rare in both groups.\n SD-treated plasma is an efficacious source of coagulation factors for patients with liver disease who are undergoing biopsy or transplantation. Assessment of seroconversion for viral markers in recipients of plasma-derived products and plasma components should include consideration of the possibility that passively transferred antibodies were detected." ]

[ "To evaluate the therapeutic efficacy of sulfadoxine-pyrimethamine, amodiaquine, and the sulfadoxine-pyrimethamine-amodiaquine combination for the treatment of uncomplicated Plasmodium falciparum malaria in young children in Cameroon.\n In a randomized study we evaluated the effectiveness and tolerance of (i) sulfadoxine-pyrimethamine (SP) (25 mg/kg body weight of sulfadoxine and 1.25 mg/kg of pyrimethamine in a single oral dose), (ii) amodiaquine (AQ) (30 mg/kg body weight in three divided daily doses), and (iii) the sulfadoxine-pyrimethamine-amodiaquine combination (SP+AQ) (same doses as in the other two treatment groups, given simultaneously on day 0) in young children in southern Cameroon. The parasitological and clinical responses were studied until day 28 in accordance with the modified 1996 WHO protocol for the evaluation of the therapeutic efficacy of antimalarial drugs.\n Of 191 enrolled patients, 6 and 8 were excluded or lost to follow-up before day 14 and between day 14 and day 28, respectively. For the AQ-treated patients, parasitological and clinical evaluation on day 14 showed late treatment failure in 2 of 61 (3.3%) and adequate clinical response with parasitological failure in one (1.6%). There was an adequate clinical response in all patients treated with SP or SP+AQ. Therapeutic failure rates on day 28 were 13.6%, 10.2% and 0% in the SP, AQ, and SP+AQ groups, respectively. Anaemia improved in all three regimens. AQ produced faster fever clearance but was associated with more transient minor side-effects than SP. SP+AQ reduced the risk of recrudescence between day 14 and day 28 but increased the incidence of minor side-effects.\n SP+AQ can be recommended as a temporary means of slowing the spread of multidrug resistance in Plasmodium falciparum in Africa while the introduction of other combinations, including artemisinin derivatives, is awaited.", "The safety and the efficacy of amodiaquine (AQ) alone, AQ plus sulfadoxine-pyrimethamine (SP) (AQ plus SP), and artesunate (ART) plus SP (ART plus SP), three possible alternatives to chloroquine (CQ), were investigated in 379 Rwandan children 6-59 months old with uncomplicated Plasmodium falciparum malaria who visited one urban/peri-urban health center and two rural health centers. The three treatment regimens were well tolerated and no serious adverse effects were observed. Children treated with AQ plus SP had less clinical failures than those treated with ART plus SP (odds ratio [OR] = 0.25, 95% confidence interval [CI] = 0.06-0.81, P = 0.01) or AQ alone (OR = 0.33, 95% CI = 0.07-1.10, P = 0.08). Even after new infections were excluded, AQ plus SP was still significantly more efficacious than ART plus SP (P = 0.05). At day 14, the mean packed cell volume was significantly higher in the AQ plus SP group compared with the ART plus SP group (P = 0.02) and with the AQ alone group (P = 0.01). In Rwanda, AQ plus SP has been chosen to replace CQ as a first-line treatment. However, this is considered an interim measure and new combinations, possibly co-formulated, should be identified and tested.", "The safety and efficacy of amodiaquine (AQ), sulfadoxine-pyrimethamine (SP), and coadministered AQ+SP was assessed in 351 Tanzanian children (age range, 6-59 months) with uncomplicated Plasmodium falciparum malaria. This open, randomized study followed the 28-day World Health Organization (WHO) protocol and evaluated safety using clinical and laboratory parameters. Children receiving SP were more likely to vomit during follow-up (32% vs. 17%: P = 0.03), and SP alone resulted in prolonged fever clearance times. Although Day 7 and Day 14 clinical and parasitological cure rates were similar, by Day 28 45% of children treated with AQ demonstrated R1 resistance and 27.5% were clinical failures compared with 25% and 6.3%, respectively, for SP alone. Coadministered AQ+SP was safe, combined the greater clinical (96.2%) and parasitological (64.2%) efficacy of SP with the more rapid symptom resolution of AQ, and reduced the incidence of gametocytemia during follow-up (AQ+SP 12.6% vs. SP 29.9%; P = 0.001). The level of R1 resistance to SP may herald a rapid decline in its efficacy as SP drug pressure increases. Coadministration of AQ+SP may delay this.", "The therapeutic efficacy of sulfadoxine-pyrimethamine (SP) alone, SP plus amodiaquine (AQ), and SP plus artesunate (AS) was assessed in a randomized, placebo-controlled, and double-blind trial among 438 children with uncomplicated Plasmodium falciparum malaria in northern Ghana. Clinical and parasitological responses were monitored for 28 days following treatment; 86%, 98% and 97% of SP-, SP + AQ-, and SP + AS-treated patients achieved adequate clinical and parasitological response (ACPR) within 2 weeks, respectively. Parasite clearance was better with SP + AS than with SP or SP + AQ treatment but re-infections were more common. Polymerase chain reaction (PCR)-corrected rates of ACPR at day 28 were 72.2% for SP, 94.1% for SP + AQ (P < 0.0001), and 94.5% for SP + AS (P < 0.0001). Gametocyte prevalence and density 1 week after treatment were highest in children treated with SP, and lowest in patients receiving SP + AS. No severe adverse events attributable to study medication were observed. In northern Ghana, more than one of four children suffered SP treatment failure within 4 weeks. Both SP + AQ and SP + AS are efficacious alternative therapeutic options in this region. Although SP + AS and SP + AQ treatments have virtually identical cure rates, rapid parasite clearance and pronounced gametocidal effects are the advantages of the former, whereas cost and a lower rate of late re-infections are those of the latter." ]

[ "Pin-site infection is a common complication of external fixation. Because few studies have compared methods of pin care that reduce infection rate, there is a need for evidence-based practice guidelines for pin-site care.\n Two of 10 original clinical centers completed a prospective, randomized pin-care study between May 2000 and May 2002 to determine which of seven methods for caring for skeletal pins (external fixator, traction, or halo) resulted in the fewest pin-site infections.\n The 92 subjects had an average infection rate of 34%, and the 527 pins had a rate of 20%. Thirty patients (98 pins) had stage II infections, two patients (12 pins) had stage III infections, and none had deep infection or osteomyelitis. The protocols were (1) half-strength peroxide cleansing and gauze wraps (45%), (2) half-strength peroxide cleansing and Xeroform wraps (9%), (3) saline cleansing and gauze wraps (33%), (4) saline cleansing and Xeroform wraps (26%), (5) antibacterial soap-and-water cleansing and gauze (38%), (6) antibacterial soap-and-water cleansing and Xeroform gauze (50%), and (7) stable dressings with no pin cleansing (36%). Logistic regression analysis demonstrated significant inverse relationships (p = .05) between infection rate and age, as well as fixator type; the latter may be related to exposed threads.\n Results suggest that other factors outside the realm of this study may affect children's pin-site infection rate and that half-strength peroxide and Xeroform dressings were superior to soap-and-water cleansing. This pilot study indicates a need for further research with a larger sample size and for exploring factors in a younger population.", "Community pharmacists have increasing involvement in the self-management of minor illness as a result of the availability of a wider range of over-the-counter (OTC) medicines. We undertook a randomized controlled trial (RCT) to assess the effectiveness and efficiency of educational strategies to implement evidence-based guidelines for the sale of OTC anti-fungals in the community pharmacy setting.\n The aim of the study was to compare the effectiveness and efficiency of two guideline dissemination strategies in community pharmacy settings.\n A 2 x 2 factorial, cluster RCT was conducted with 60 community pharmacies in the Grampian region of Scotland. The interventions included dissemination of an evidence-based guideline for OTC management of vulvovaginal candidiasis (thrush) by postal dissemination (control), educational outreach visit or attendance at a continuing professional education session. Pre- and post-intervention simulated patient visits were made to participating pharmacies. The simulated patients completed assessment forms following each visit. The primary outcome was the appropriateness (based upon the guidelines) of sale or no sale of OTC anti-fungals.\n There were no significant differences in the proportion of appropriate outcomes following educational outreach [odds ratio (OR) = 1.1; 95% confidence interval (CI) 0.52 to 2.45] or continuing professional education (OR = 0.88; 95% CI 0.41 to 1.91).\n Neither strategy was effective in improving the appropriateness of OTC management of vulvovaginal candidiasis by community pharmacy staff.

After 15 days, patients in group 1 (20 cases, 310 pin sites) were advised to perform pin care by daily showering and brushing the pin sites with soap and an ordinary soft toothbrush, whereas patients in group 2 (19 cases, 300 pin sites) were advised to perform pin care by daily showering and cleaning the crusts using sterile gauze impregnated with 10% polyvinylpyrrolidone iodine (Polyod). Each pin site was denominated according to location.\n Pin sites were inspected and graded on a scale of 0 to 5 according to slight modification of the system of Dahl described by Gordon et al during outpatient visits on the 5th, 10th, 15th, 30th, 45th, 60th, 75th, 90th, 120th, and 150th days of follow up after the operation until fixator removal. Grade 1 and grade 2 infections were categorized as minor infection not requiring any extra pin site care and grade 3 and above infections as major infection.\n Minor infection rate of all pin sites was determined as 50.7% in group 1 and 43.6% in group 2. Major infection rate was determined as 3.5% in group 1 and 3.7% in group 2. No statistically significant difference was noted between the two groups (all P > 0.05).\n Pin site care can be performed without impairing patient comfort and without prohibition of showering.

Outcomes were measured in 16 939 consultations for sore throat and 9887 consultations for urinary tract infection.\n Interventions were developed to overcome identified barriers to implementing the guidelines. The main components of the tailored interventions were patient educational material, computer based decision support and reminders, an increase in the fee for telephone consultations, and interactive courses for general practitioners and practice assistants.\n Changes in rates of use of antibiotics, laboratory tests, and telephone consultations. Results: Patients in the sore throat group were 3% less likely to receive antibiotics after the intervention. Women with symptoms of urinary tract infection in the intervention group were 5.1% less likely to have a laboratory test ordered. No significant differences were found between the groups for the other outcomes. Large variation was found across the included practices in the rates of antibiotic prescription, use of laboratory tests and telephone consultations, and in the extent of change for all three outcome measures.\n Passively delivered, complex interventions targeted at identified barriers to change had little effect in changing practice.", "We investigated whether there were any differences in the frequency and severity of pin site infections by performing pin site care daily or once a week.

We evaluated pin sites, the occurrence of pain (VAS), the use of antibiotics and analgesics and complications every week. Bacterial cultures were taken from each pin site at 1, 6 and 10 weeks and from the pins on removal.\n We found no differences between daily or weekly pin site care as regards the frequency and severity of pin site infections, pain, or the use of antibiotics and analgesics. Grade I infections (Checketts-Otterburns classification) occurred around 11% of the pins and grade II infections around 4%. 70% of the bacterial cultures were negative. The most frequent bacteria were coagulase negative staphylococcus and corynebacterium. Antibiotics were given an average of 47 days. More problems occurred around the proximal pins. 5/200 (all proximal) pins were clinically loose on removal.\n Pin site care once a week seems appropriate." ]

The extrapyramidal symptoms of each patient were compared when taking their usual anticholinergic medication, when taking placebo and when taking no antiparkinsonian drug. The relapse rate on no medication was 14%, and if patients relapsed on no medication they also relapsed on placebo. The relapse rate was not significantly different on active medication. Nor were there significant differences in ratings of parkinsonism or dyskinesia.

To test whether cholinesterase inhibitors compensate for diminished cholinergic activity, we conducted a 30-week randomized, double-blind, placebo-controlled crossover trial of galantamine in patients with tardive dyskinesia.\n Patients with tardive dyskinesia were recruited between June 2001 and June 2004. After a 2-week baseline period, 35 male schizophrenia patients, on stable doses of antipsychotics, were randomly assigned to receive galantamine (8-24 mg) or placebo for two 12-week phases separated by a 4-week washout period. Patients were evaluated every 2 weeks for changes in extrapyramidal symptoms and before and after each treatment for effects on psychiatric symptoms and cognition.\n Galantamine reduced mean total Abnormal Involuntary Movement Scale (AIMS) scores more than placebo, but this difference was not statistically significant (p = .08). However, patients initially randomly assigned to galantamine showed a reversal of AIMS scores after switching to placebo. Simpson-Angus Scale ratings of parkinsonism were significantly higher with galantamine than placebo (p = .0005) and correlated with age. There were no significant differences between groups in akathisia, cognition, or psychiatric symptoms. More patients dropped out while receiving galantamine, but this outcome did not significantly influence the results.\n In contrast to previous reports, reductions in tardive dyskinesia associated with galantamine were not statistically significant compared with placebo in this trial. However, galantamine was associated with a modest rebound in dyskinesia scores after discontinuation and clinically minor but statistically higher ratings of parkinsonism. These findings support the need for further investigations of cholinergic mechanisms underlying tardive dyskinesia and extrapyramidal effects of cholinesterase inhibitors when used in combination with antipsychotics in susceptible patients.\n ClinicalTrials.gov identifier NCT00164242.", "The objectives of this randomized clinical trial were to investigate the impact of the discontinuation of long-term antipsychotics in residents with dementia in chronic care institutions and to identify clinical predictors of safe discontinuation. Subjects included 34 residents with dementia who were on antipsychotics for more than 6 months and whose behavior was currently stable. Subjects were randomized to either continue receiving their regular dosage of antipsychotics or to receive placebo for 6 months. Early withdrawal from the study was not statistically different between the groups (relative risk [RR] = 1.57, 95% confidence interval [CI] 0.76-3.26), and though not significantly different, subjects in the placebo group were more likely to be withdrawn from the study because of worsening behavior (RR = 1.25, 95% Cl 0.33-4.76). Three subjects in the placebo group were withdrawn from the study due to worsening of extrapyramidal symptoms. The active treatment group had more behavioral problems (e.g., physical aggression towards others, p < .05) compared to the placebo group. The placebo group developed more apathy, but balancing this outcome was a relative improvement in cognitive functioning. Baseline antipsychotic dose was predictive of behavioral worsening upon discontinuation of long-term antipsychotic drugs. The primary limitation of the study was the small sample size. In conclusion, a trial of discontinuation of antipsychotics should be considered in this population.", "Poor specificity of face-value endpoints and the poor sensitivity of gross clinical examination may have militated against demonstrating prophylaxis by selegiline.\n Objective measures of the four cardinal signs were used as primary outcome criteria in a randomised, double-blind, placebo-controlled, parallel group study of selegiline monotherapy in 25 newly diagnosed elderly sufferers from idiopathic parkinsonism, stratified for sex and Hoehn and Yahr functional staging.\n There was a significant interaction between time and nature of treatment with respect to rigidity. The effect of time during active treatment was highly significant: rigidity decreased by 1.3% per week. The worsening of rigidity on placebo was not statistically significant. Neuronal rescue is a possible explanation for the long term, progressive improvement produced by selegiline. No significant treatment effect was seen on the other cardinal signs. However, there was a significant quadratic time trend for arousal on active treatment suggesting tolerance to this effect.\n The difference in time course between the psychostimulant and physical effects suggests more than one mode of action.", "To establish the effect of the atypical neuroleptic clozapine on chorea, voluntary motor performance, and functional disability in patients with Huntington's disease.\n Thirty three patients with Huntington's disease participated in a double blind randomised trial. A maximum of 150 mg/day clozapine or placebo equivalent was given for a period of 31 days. Assessments were performed in the week before and at the last day of the trial. Chorea was scored using the abnormal involuntary movement scale (AIMS), the chorea score of the unified Huntington's disease rating scale (UHDRS), and judgement of video recordings. Voluntary motor performance was assessed using the UHDRS motor scale. Patients and their partners completed a questionnaire regarding functional disability. Twelve patients already used other neuroleptic medication, which was kept unchanged during the trial period. Results of neuroleptic naive and neuroleptic treated patients were analysed separately.\n Clozapine tended to reduce chorea in neuroleptic naive patients only (AIMS); improvement seemed more pronounced in patients receiving higher doses of clozapine. Other measures of chorea (UHDRS chorea score, video ratings) showed no improvement. Clozapine had no beneficial effect on chorea in patients already receiving neuroleptic medication. Voluntary motor performance did not improve with clozapine. Neuroleptic naive patients reported aggravation of functional disability, possibly reflecting the frequent occurrence of side effects. Adverse reactions forced trial termination in six patients and dose reduction in another eight, and consisted mainly of drowsiness, fatigue, anticholinergic symptoms, and walking difficulties.\n Clozapine has little beneficial effect in patients with Huntington's disease, although individual patients may tolerate doses high enough to reduce chorea. Because adverse reactions are often encountered, clozapine should be used with restraint in this patient group.", "To explore the effect on sleep/wake activity and on behavioral and psychological symptoms of the withdrawal of antipsychotic medications from nursing home (NH) patients with dementia.\n Randomized, placebo-controlled, double-blind trial.\n NHs in Bergen, Norway.\n Thirty patients (mean age 83.5) taking haloperidol, risperidone, or olanzapine for nonpsychotic symptoms. Intervention: Study participants were randomly assigned to withdrawal (intervention group) or continued treatment with antipsychotic medications (reference group) for 4 consecutive weeks.\n Behavioral rating using the Neuropsychiatric Inventory Questionnaire (NPI-Q) and actigraphy.\n After antipsychotic withdrawal, behavioral scores remained stable or improved in 11 of 15 patients, whereas four had worsening scores. Actigraphy revealed decreased sleep efficiency after drug discontinuation and increased 24-hour and night activity in both groups. Actigraphy records of nighttime and daytime activity indicated sleep problems and restlessness, in terms of the NPI-Q. One patient was restarted on antipsychotics.\n Antipsychotic drug withdrawal affected activity and sleep efficiency over the short term. Increases in total activity and impaired sleep quality after drug discontinuation should be monitored, because the long-term effect of these changes is not known. The NPI-Q and actigraphy are feasible tools that disclose relevant changes occurring during antipsychotic withdrawal in NH patients with dementia. Their use in clinical practice should be substantiated by larger studies." ]

[ "To compare the efficacy and safety of two surfactant preparations in the treatment of respiratory distress syndrome (RDS).\n We conducted a randomized, masked comparison trial at 21 centers. Infants with RDS who were undergoing mechanical ventilation were eligible for treatment with two doses of either a synthetic (Exosurf) or natural (Infasurf) surfactant if the ratio of arterial to alveolar partial pressure of oxygen was less than or equal to 0.22. Crossover treatment was allowed within 96 hours of age if severe respiratory failure (defined as two consecutive arterial/alveolar oxygen tension ratios < or = 0.10) persisted after two doses of the randomly assigned surfactant. Four primary outcome measures of efficacy (the incidence of pulmonary air leak (< or = 7 days); the severity of RDS; the incidence of death from RDS; and the incidence of survival without bronchopulmonary dysplasia (BPD) at 28 days after birth) were compared by means of linear regression techniques.\n The primary analysis of efficacy was performed in 1033 eligible infants and an analysis of safety outcomes in the 1126 infants who received study surfactant. Preentry demographic characteristics and respiratory status were similar for the two treatment groups, except for a small but significant difference in mean gestational age (0.5 week) that favored the infasurf treatment group. Pulmonary air leak (< or = 7 days) occurred in 21% of Exosurf- and 11% of infasurf-treated infants (adjusted relative risk, 0.53; 95% confidence interval, 0.40 to 0.71; p < or = 0.0001). During the 72 hours after the initial surfactant treatment, the average fraction of inspired oxygen (+/-SEM) was 0.47 +/- 0.01 for Exosurf- and 0.39 +/- 0.01 for infasurf-treated infants (difference, 0.08; 95% confidence interval, 0.06 to 0.10; p < 0.0001); the average mean airway pressure (+/-SEM) was 8.6 +/- 0.1 cm H2O; for Exosurf- and 7.2 +/- 0.1 cm H2O for Infasurf-treated infants (difference, 1.4 cm H2O; 95% confidence interval, 1.0 to 1.8 cm H2O; p < 0.0001). The incidences of RDS-related death, total respiratory death, death to discharge, and survival without bronchopulmonary dysplasia at 28 days after birth did not differ. The number of days of more than 30% inspired oxygen and of assisted ventilation, but not the duration of hospitalization, were significantly lower in Infasurf-treated infants.\n Compared with Exosurf, Infasurf provided more effective therapy for RDS as assessed by significant reductions in the severity of respiratory disease and in the incidence of air leak complications.", "We performed a randomized, prospective clinical trial comparing intratracheal administration of human surfactant with conventional treatment with intermittent mandatory mechanical ventilation alone for treatment of severe respiratory distress syndrome in preterm infants of less than 30 weeks gestation. Twenty-two infants (mean gestational age 27.0 weeks, mean birth weight 987 gm) were given surfactant, and 23 infants (mean gestational age 27.2 week, mean birth weight 1055 gm) received intermittent mandatory ventilation. Infants given surfactant required less FiO2 during the first week, had lower mean airway pressure during the first 48 hours, and had improved ventilatory index and a/A PO2 ratio. Death or the occurrence of bronchopulmonary dysplasia was significantly less among infants given surfactant (P = 0.019). Pneumothorax, pulmonary interstitial emphysema, and need for FiO2 greater than or equal to 0.3 for greater than 30 days was significantly less in the surfactant group. This trial confirms the efficacy of treatment with human surfactant in preterm infants with severe respiratory distress syndrome.", "To determine whether a single prophylactic dose of synthetic surfactant would reduce mortality and morbidity rates, we performed a randomized, controlled trial of Exosurf Neonatal at 19 hospitals in the United States. The Exosurf preparation (5 ml/kg) was instilled into the endotracheal tube of premature infants weighing 700 to 1100 gm during mechanical ventilation, as soon as practical after birth. Control infants were treated with air (5 ml/kg). Dose administration was performed in secrecy by clinicians who did not reveal for 2 years what they had instilled. A total of 222 infants received air and 224 received the synthetic surfactant; 36 infants with congenital pneumonia or malformations were excluded from the primary efficacy analysis. By the age of 28 days, there were 44 deaths in the air group and 27 deaths in the surfactant group (p = 0.022). By the age of 1 year after term there were 61 deaths in the air group and 35 deaths in the surfactant group (p = 0.002). Although there was no reduction in the incidence of respiratory distress syndrome, a significant reduction in the number of deaths attributed to respiratory distress syndrome, a significant reduction in the incidence of pulmonary air leaks, and significantly lower requirements for oxygen and mean airway pressure indicated that lung disease was less severe in the Exosurf-treated infants. There were no significant differences in the incidence of complications such as bronchopulmonary dysplasia, intraventricular hemorrhage, patent ductus arteriosus, necrotizing enterocolitis, and infection. The results indicate that a single prophylactic dose of Exosurf, in high-risk premature infants treated soon after birth, reduces the number of deaths from respiratory distress syndrome and the overall mortality rate.", "To compare the efficacy and safety of a synthetic surfactant (Exosurf Neonatal, Burroughs Wellcome Co) and a surfactant extract of calf lung lavage (Infasurf, IND #27,169, ONY, Inc) in the prevention of neonatal respiratory distress syndrome (RDS).\n Ten-center randomized masked comparison trial.\n Premature infants (n = 871) <29 weeks gestational age by best obstetric estimate.\n Infants were randomly assigned to a course of treatment with Exosurf Neonatal (n = 438) or Infasurf (n = 433) at birth, and if still intubated, at 12 and 24 hours of age. Crossover treatment was allowed within 72 hours of age if severe respiratory failure (defined as two consecutive a/A PO2 ratios </=.10) persisted after three doses of the randomized surfactant. Primary\n Three primary outcome measures of efficacy [the incidence of RDS; the incidence of RDS death; and the incidence of survival without bronchopulmonary dysplasia at 28 days after birth] were compared using linear regression techniques.\n Of 871 randomized infants, 18 infants did not receive treatment with a study surfactant, and 25 infants did not meet all eligibility criteria. The primary analysis of efficacy was performed in the 846 eligible infants and analysis of safety outcomes in the 853 infants who received study surfactant. Demographic characteristics did not differ between the two treatment groups. Compared with Exosurf, Infasurf treatment resulted in a 62% decrease in the incidence of RDS (Infasurf, 16% vs Exosurf, 42%) and a 70% decrease in RDS death (Infasurf, 1.7% vs Exosurf, 5.4%) but did not increase the incidence of survival without bronchopulmonary dysplasia at 28 days. Treatment with Infasurf resulted in significant improvement in several secondary outcome measures. Infasurf-treated infants had lower average FIO2 (Infasurf, .33 [SEM] vs Exosurf, .42; difference .08; 95% confidence interval [CI], .06 to .11) and average mean airway pressure (Infasurf, 6.0 cm H2O vs Exosurf, 7.1 cm H2O; difference 1.1 cm H2O; 95% CI, .7 to 1.6 cm H2O) for the first 72 hours of life. Crossover surfactant treatment was significantly less frequent in the Infasurf compared with the Exosurf group (Infasurf, 1% vs Exosurf, 6%). Complications (bradycardia, clinical airway obstruction, and transcutaneous arterial desaturation) associated with second and third, but not initial, surfactant treatments were observed more frequently in the Infasurf treatment group. Infasurf-treated infants had significantly less air leak (</=7 days) (Infasurf, 8% vs Exosurf, 14%; adjusted relative risk [ARR] .55; 95% CI, .37 to .81). Severe intraventricular hemorrhage (IVH) (grade 3 and 4) did not differ between the two groups (Infasurf, 11.8% vs Exosurf, 8.3%; ARR 1.41; 95% CI, .94 to 2.09) but total IVH occurred more frequently in Infasurf-treated infants (Infasurf, 39.0% vs Exosurf, 29.9%; ARR, 1.30; 95% CI, 1.08 to 1.57).\n Significant reductions in the incidence of RDS, the severity of early respiratory disease, the incidence of pulmonary air leaks associated with RDS, and the mortality attributable to RDS suggest that Infasurf is a more effective surfactant preparation than Exosurf Neonatal in the prophylaxis of RDS. However, Infasurf prophylaxis as used in this study was also associated with a greater risk of total but not severe IVH.", "In a randomized, controlled study, human surfactant derived from amniotic fluid was administered within 12 hours of birth to infants with severe respiratory distress syndrome who were born at 24 to 32 weeks of gestation weighing less than or equal to 1500 gm. A second dose of surfactant was given to patients in the treatment group if they met ventilator requirements indicating relapse or lack of response to the initial dose. No significant improvement was observed in mortality rate (9/28 vs 15/31) or incidence of bronchopulmonary dysplasia (5/28 vs 3/31) when surfactant-treated infants were compared with control subjects, although there was a significant reduction in initial respirator and inspired oxygen requirements and the arterial/alveolar oxygen ratio improved. In addition, there was a significant reduction in pulmonary air leak in treated infants (10/28 vs 20/31; p less than 0.05). Retreatment was associated with an attenuated ventilatory response and with a higher mortality rate (7/14) than that of infants who did not require a second dose (2/14; p = 0.05), indicating a more severe form of disease. Multiple discriminant analysis, including eight independent variables, revealed that increasing birth weight, earlier age at surfactant treatment, and female gender were significantly associated with survival. These data suggest that early surfactant treatment may reduce mortality rates in very low birth weight infants with severe respiratory distress syndrome, as well as reduce ventilator requirements and the incidence of pulmonary air leaks.", "We performed a multicenter prospective randomized controlled trial to determine the efficacy and safety of the surfactant preparation, Survanta (Abbott Laboratories, Chicago, USA), for 750-1750 g infants with idiopathic respiratory distress syndrome, (IRDS) receiving assisted ventilation with 40% or more oxygen. One hundred and six eligible infants from the eight participating centers were randomly assigned between March 1986 and June 1987 to receive either surfactant (100 mg phospholipid/kg, 4 ml/kg) or air (4 ml/kg) administered into the trachea within 8 h of birth (median time of treatment 6.2 h, range 3.2-9.1 h). The study was stopped before enrollment was completed at the request of the United States Food and Drug Administration when significant differences were observed in incidence of periventricular-intraventricular hemorrhage (PIH), between the surfactant treated and control infants. Surfactant treated infants had larger average increases in the arterial-alveolar oxygen ratio, (a/A ratio) (P less than 0.0001), and larger average decreases in FiO2 (P less than 0.0001) and mean airway pressure, (MAP) (P less than 0.017) than controls over the 48 h following treatment. The magnitude of the differences between the surfactant and control groups were 0.19 (SE = 0.03) for a/A ratio, -0.28 (SE = 0.04) for FiO2 and -1.7 cm H2O (SE = 0.70) for MAP. The clinical status on days 7 and 28 after treatment was classified using four predefined ordered categories: (1) no respiratory support; (2) supplemental O2 with or without continuous positive airway pressure (CPAP); (3) intermittent mandatory ventilation; and (4) death. There were no statistically significant differences in the status categories on days 7 or 28 between surfactant and control infants.(ABSTRACT TRUNCATED AT 250 WORDS)", "The effects of a single dose of surfactant TA were assessed in premature neonates (birth weight 750 to 1749 g) with respiratory distress syndrome (RDS) in a multicenter, double-blind, randomized clinical trial. Only neonates with surfactant deficiency and without ultrasonographic evidence of intracranial hemorrhage greater than or equal to grade II were enrolled. Fifty-four patients received surfactant (100 mg of phospholipid per kilogram of body weight) and 46 patients received an air placebo within 8 hours of life. Treatment with this surfactant resulted in a significant reduction in the severity of RDS with a concomitant increase in the proportion of neonates with mild disease. The frequency of pulmonary interstitial emphysema and of pneumothorax was significantly lower in treated neonates compared with control neonates (2% vs 26%, P = .0008, and 7% vs 39%, P = .0004, respectively). The frequency of intracranial hemorrhage was significantly lower in the surfactant group compared with the control group (20% vs 54%, P = .0008) and was also reduced for the smallest neonates in the surfactant group (13% vs 73%, P = .00008). When categorized according to severity of intracranial hemorrhage and severity of bronchopulmonary dysplasia, the surfactant group was at a significant advantage (adjusted Cochran-Mantel-Haenszel X2 = 10.72, P less than .001 and X2 = 4.43, P = .036, respectively). The proportion of neonates surviving without intracranial hemorrhage and/or bronchopulmonary dysplasia was 63% in the surfactant group vs 26% in the control group (P = .0004); as for the smallest neonates, it was 58% in the surfactant group vs 4% in the control group (P = .0002). There were no differences between the groups with respect to the frequency of patent ductus arteriosus (46% vs 37%), pulmonary hemorrhage (6% vs 7%), necrotizing enterocolitis (0% vs 2%), sepsis (4% vs 2%), retinopathy of prematurity (13% vs 22%), or death (15% vs 22%). It is concluded that treatment with the single-dose surfactant regimen used in this study reduces the severity of respiratory distress during the 48 hours after treatment and decreases the major pulmonary morbidity and intracranial hemorrhage in premature neonates with RDS. Further studies are needed to determine whether (1) treatment at birth or as soon as after RDS is diagnosed and (2) the use of multiple dose of this surfactant would result in any additional benefits.", "In southern Scandinavia most babies with respiratory distress syndrome are initially treated with nasal continuous positive airway pressure. We performed a multicenter trial to investigate whether the addition of a single dose of porcine surfactant administered during a short intubation before the occurrence of serious deterioration could reduce the subsequent need for mechanical ventilation.\n We randomly assigned 35 infants with moderate-to-severe respiratory distress syndrome to surfactant therapy (Curosurf, 200 mg per kilogram of body weight) plus nasal continuous positive airway pressure and 33 infants to nasal continuous positive airway pressure alone. The study was not blinded. The indications for mechanical ventilation were a ratio of arterial to alveolar oxygen tension of less than 0.15, severe apneic attacks, or both.\n Six hours after randomization, when the median age of the babies was 18 hours, the mean ratio of arterial to alveolar oxygen tension was 0.37 in the surfactant-treated babies, as compared with 0.25 in the controls (P < 0.001). The need for subsequent mechanical ventilation was reduced with surfactant therapy (to 43 percent of the surfactant-treated babies as compared with 85 percent of the controls; P = 0.003). When 17 infants with ratios of arterial-to-alveolar oxygen tension of less than 0.15 at randomization were excluded, the need for mechanical ventilation was still significantly reduced in the surfactant-treated group (to 33 percent [9 of 27 babies], as compared with 83 percent [20 of 24 babies] in the control group; (P < 0.001). After 28 days, two of the surfactant-treated babies had died, as compared with five of the control babies.\n In babies with moderate-to-severe respiratory distress syndrome treated with nasal continuous positive airway pressure, a single dose of surfactant reduced the need for subsequent mechanical ventilation." ]

[ "Studies in the USA and Japan have shown that tacrolimus (FK506) is a potent immunosuppressant. To compare the efficacy and safety of tacrolimus-based and conventional cyclosporin-based immunosuppressive regimens we recruited 545 liver transplant recipients from eight European centres into a randomised open trial. Analysis of the data at 12 months post-transplant showed that tacrolimus was associated with a significant reduction in acute, refractory acute, and chronic rejection episodes. The rates were, for acute rejection, tacrolimus 40.5% vs 49.8% cyclosporin (p = 0.040; absolute difference 9.3% [95% CI 0.9-17.8%]). For refractory acute and chronic rejections the comparisons were 0.8% vs 5.3% (p = 0.005) and 1.5% vs 5.3% (p = 0.032). There results were seen despite significantly lower corticosteroid usage. The incidence of infection was also lower in patients receiving tacrolimus. Patient and graft survival rates were not significantly different (tacrolimus 82.9% and 77.5%; cyclosporin 77.5% and 72.6%). Safety data were comparable--the most serious events being renal impairment, disturbances of glucose metabolism, and neurological complications--but these events were more common in the tacrolimus group. In this trial tacrolimus had advantages over cyclosporin in respect of lower rejection rates, even though less concurrent immunosuppression was administered.", "Tacrolimus (FK506), a macrolide molecule that potently inhibits the expression of interleukin 2 by T lymphocytes, represents a potential major advance in the management of rejection following solid-organ transplantation. This randomized, open-label study compared the efficacy and safety of tacrolimus-based versus cyclosporine-based immunosuppression in patients receiving cadaveric kidney transplants.\n A total of 412 patients were randomized to tacrolimus (n=205) or cyclosporine (n=207) after cadaveric renal transplantation and were followed for 1 year for patient and graft survival and the incidence of acute rejection.\n One-year patient survival rates were 95.6% for tacrolimus and 96.6% for cyclosporine (P=0.576). Corresponding 1-year graft survival rates were 91.2% and 87.9% (P=0.289). There was a significant reduction in the incidence of biopsy-confirmed acute rejection in the tacrolimus group (30.7%) compared with the cyclosporine group (46.4%, P=0.001), which was confirmed by blinded review, and in the use of antilymphocyte therapy for rejection (10.7% and 25.1%, respectively; P<0.001). Impaired renal function, gastrointestinal disorders, and neurological complications were commonly reported in both treatment groups, but tremor and paresthesia were more frequent in the tacrolimus group. The incidence of posttransplant diabetes mellitus was 19.9% in the tacrolimus group and 4.0% in the cyclosporine group (P<0.001), and was reversible in some patients.\n Tacrolimus is more effective than cyclosporine in preventing acute rejection in cadaveric renal allograft recipients, and significantly reduces the use of antilymphocyte antibody preparations. Tacrolimus was associated with a higher incidence of neurologic events, which were rarely treatment limiting, and with posttransplant diabetes mellitus, which was reversible in some patients.", "Our clinical trial was designed to investigate the optimal combination of immunosuppressants for renal transplantation.\n A randomized three-arm, parallel group, open label, prospective study was performed at 15 North American centers to compare three immunosuppressive regimens: tacrolimus + azathioprine (AZA) versus cyclosporine (Neoral) + mycophenolate mofetil (MMF) versus tacrolimus + MMF. All patients were first cadaveric kidney transplants receiving the same maintenance corticosteroid regimen. Only patients with delayed graft function (32%) received antilymphocyte induction. A total of 223 patients were randomized, transplanted, and followed for 1 year.\n There were no significant differences in baseline demography between the three treatment groups. At 1 year the results are as follows: acute rejection 17% (95% confidence interval 9%, 26%) in tacrolimus + AZA; 20% (confidence interval 11%, 29%) in cyclosporine + MMF; and 15% (confidence interval 7%, 24%) in tacrolimus + MMF. The incidence of steroid resistant rejection requiring antilymphocyte therapy was 12% in the tacrolimus + AZA group, 11% in the cyclosporine + MMF group, and 4% in the tacrolimus + MMF group. There were no significant differences in overall patient or graft survival. Tacrolimus-treated patients had a lower incidence of hyperlipidemia through 6 months posttransplant. The incidence of posttransplant diabetes mellitus requiring insulin was 14% in the tacrolimus + AZA group, 7% in the cyclosporine + MMF and 7% in the tacrolimus + MMF groups.\n All regimens yielded similar acute rejection rates and graft survival, but the tacrolimus + MMF regimen was associated with the lowest rate of steroid resistant rejection requiring antilymphocyte therapy.", "The long-term complications of immunosuppressive therapy such as diabetes, hypercholesterolemia, and hypertension are a major source of morbidity in liver transplant recipients. In this prospective, randomized, open-label study we completely withdrew prednisone (PRED) 14 days after liver transplantation in an effort to decrease these metabolic complications. Patients were maintained on mycophenolate mofetil (MMF) in combination with either cyclosporine (CsA; Neoral formulation) or tacrolimus (TAC). Thus, we also were able to compare CsA to TAC in patients not receiving PRED with respect to efficacy, toxicity, and effect on posttransplant metabolic complications.\n A total of 71 patients were randomized to receive either TAC-MMF (n=35) or CsA-MMF (n=36) after liver transplantation and were analyzed for patient and graft survival. Fifty-eight patients continued the immunosuppressive protocol for at least 6 months after transplantation and were analyzed for the incidence of acute rejection and the prevalence of diabetes, hypertension, and hypercholesterolemia.\n The 6-month patient survival rates were 94.4% for CsA-MMF and 88.6% for TAC-MMF. Corresponding 6-month graft survival rates were 88.7% and 85.71% with no immunologic graft losses in either group. The incidence of biopsy-proven acute rejection was 46% for CsA-MMF and 42.3% for TAC-MMF. Six patients were converted from CsA to TAC (four for recurrent rejection) and seven patients were converted from TAC to CsA (four for neurotoxicity). Only one patient (in the TAC-MMF group) developed new-onset posttransplant diabetes. In contrast, four of eight patients in the CsA-MMF group who were diabetic before transplant became nondiabetic in the first 3 months after transplant. The mean serum cholesterol level was significantly lower in the TAC-MMF group than in the CsA-MMF group (145.2+/-41.8 mg/dl and 190.3+/-62.2, respectively; P<0.001) and the incidence of hypertension was lower in the TAC-MMF group (12% vs. 30.3% in the CsA-MMF group, P<0.01). Both groups had a lower incidence of metabolic complications compared with a historical group (n=100) maintained on CsA and PRED (10 mg/day at 6 months).\n MMF in combination with either TAC or CsA allows withdrawal of PRED 14 days after liver transplantation with a moderate rejection rate and no immunologic graft losses. Early PRED withdrawal decreases posttransplant diabetes, hypercholesterolemia, and hypertension, but patients maintained on TAC have lower serum cholesterol levels and a lower incidence of hypertension than CsA-treated patients.", "The long-term effects of tacrolimus and cyclosporine on pancreatic islet cell function in renal transplant recipients are unclear. Therefore, a prospective, randomized, longitudinal study was performed that compared glucose metabolism in adult kidney allograft recipients on tacrolimus versus cyclosporine-based immunosuppression. Twenty-three white renal allograft recipients, randomized for either therapy with cyclosporine or tacrolimus, underwent intravenous glucose tolerance tests 6 times during the first 3 yr after transplantation. Concomitant therapy (low-dose steroids and azathioprine) was the same in both groups. Insulin sensitivity index (kG), insulin resistance (insulin/glucose ratio and homeostasis model assessment), and C-peptide and insulin secretion were calculated. Trough levels of tacrolimus and cyclosporine were measured. The occurrence of posttransplantation diabetes mellitus was prospectively monitored. Statistical analysis was performed by ANOVA for repeated measures, and parametric and nonparametric tests were also performed. Although only one patient treated with cyclosporine developed posttransplantation diabetes mellitus, kG levels were below normal in up to one-third of both patients who received tacrolimus and cyclosporine. The only significant difference between patients who received tacrolimus and those who received cyclosporine was in pancreatic secretion capacity at week 3 after transplantation, when the increment of C-peptide secretion was 57% lower and the increment of insulin secretion was 48% lower for patients receiving tacrolimus. In both groups, from week 3 to month 6, there was a tendency toward an increase in kG, despite a significant increase in fasting glucose and insulin resistance calculated by homeostasis model assessment. After month 6, there were no significant changes in any of the parameters of glucose metabolism, indicating that long-term use of either tacrolimus or cyclosporine does not cause chronic, cumulative pancreatic toxicity.", "Corticosteroid therapy contributes significant toxicity to liver transplantation. The safety and efficacy of early steroid withdrawal were determined in patients treated with either tacrolimus or microemulsion cyclosporin A (micro-CsA). The primary outcome was the proportion of patients who were steroid-free 1 year posttransplantation. From the seven Canadian adult liver transplant centers, 143 patients were randomly allocated oral treatment with either tacrolimus (n = 71) or micro-CsA (n = 72), together with corticosteroids and azathioprine. Eligibility criteria for steroid withdrawal included freedom from acute rejection for a minimum of 3 months, and prednisone </=0.15 mg/kg/d. In eligible patients, the daily steroid dose was reduced by 2.5 mg each month until complete discontinuation was achieved. At 1 year after transplantation, 75% of the tacrolimus patients and 63% of the micro-CsA patients were steroid-free (P =.20). Of all of the patients who became eligible for steroid withdrawal, steroid discontinuation was achieved in over 80%. One-year patient survival was 97% with tacrolimus and 89% with micro-CsA (P =.052). Graft survival was 97% and 86%, respectively (P =.017). The overall incidence of acute rejection during the first year was 35% with tacrolimus and 43% with micro-CsA (P =.26). There was no difference in survival, acute rejection, or rate of steroid withdrawal when adjusting for hepatitis C. All acute rejection episodes experienced during steroid withdrawal were steroid-responsive. Steroid-resistant rejection occurred in 5.6% of the tacrolimus and 9.7% of the micro-CsA patients. One patient, in the micro-CsA group, experienced refractory rejection. Chronic rejection was not observed in either group. The toxicity profiles were similar. Postoperative serum creatinine levels were similar, and dialysis was required in less than 10% of patients in each group. Infectious complications were similar in both groups. Neurotoxicity was a serious adverse event in 13% and 10% of patients receiving tacrolimus and micro-CsA, respectively. Early steroid withdrawal is safe and effective after liver transplantation using either tacrolimus plus azathioprine or micro-CsA plus azathioprine immunoprophylaxis.", "Results of studies in adult recipients of liver allograft suggest that tacrolimus is more efficacious than ciclosporin microemulsion in the prevention of acute rejection. We aimed to compare these drugs in children undergoing liver transplantation.\n This 12-month multicentre, open-label, parallel-group, randomised study compared a dual tacrolimus regimen (tacrolimus/corticosteroids, n=93) with a triple ciclosporin microemulsion regimen (ciclosporin microemulsion/corticosteroids/azathioprine, n=92) in children who had had liver transplants (age < or =16 years, bodyweight < or =40 kg). Initial oral daily doses were 0.30 mg/kg for tacrolimus and 10 mg/kg for ciclosporin microemulsion. Primary endpoint was the incidence of and time to first histologically proven acute rejection. We excluded patients from analysis if they did not receive the study drug, or were given incorrect medication. Otherwise patients were analysed in accordance with their random treatment allocation, irrespective of whether they switched medication during the trial.\n Median age was 22 months (IQR 9-56) in the tacrolimus group and 17 months (9-54) in the ciclosporin microemulsion group. We noted no difference between treatment groups with respect to patient survival (93.4% vs 92.2%; p=0.77) or graft survival (92.3% vs 85.4%; p=0.16) at month 12 after transplant. The acute rejection free rate at study end (Kaplan-Meier method) was 55.5% for patients on tacrolimus and 40.2% for patients on ciclosporin microemulsion (p=0.0288). The Kaplan-Meier estimate of patients free from corticosteroid-resistant acute rejection at study end was 94.0% for tacrolimus-treated patients and 70.4% for ciclosporin-microemulsion-treated patients (p<0.0001). Overall, incidence of adverse events did not differ between groups.\n Tacrolimus is a safe and effective treatment for the prevention of rejection after liver transplantation in children.", "To confirm the results of a number of studies conducted in Europe, the United States, and Japan, this multicenter, randomized trial compared the 12-month efficacy and safety of tacrolimus- and cyclosporine-based immunosuppressive regimens in the prevention of renal allograft rejection.\n A total of 448 renal transplant recipients were recruited from 15 centers and assigned to receive triple-drug therapy consisting of tacrolimus (n=303) or cyclosporine (n=145) in conjunction with azathioprine and low-dose corticosteroids.\n At 12 months after transplantation, tacrolimus therapy was associated with a significant reduction in the frequency of both acute (tacrolimus 25.9% vs. cyclosporine 45.7%; P<0.001 [absolute difference: 19.8%, 95% confidence interval: 10.0-29.6%]) and corticosteroid-resistant rejection (11.3% vs. 21.6%; P=0.001 [absolute difference: 10.3%, 95% confidence interval: 2.5-18.2%]). Actuarial 1-year patient (tacrolimus 93.0% vs. cyclosporine 96.5%; P=0.140) and graft survival rates (82.5% vs. 86.2%; P=0.380) did not differ significantly between the two treatment groups. Overall, the safety profiles of the tacrolimus- and cyclosporine-based regimens were quite comparable. Infections, renal impairment, neurological complications, and gastrointestinal complaints were frequently reported but were mostly reversible in both groups. Higher incidences of elevated serum creatinine, tremor, diarrhea, hyperglycemia, diabetes mellitus, and angina pectoris were reported in the tacrolimus treatment group, whereas acne, arrhythmia, gingival hyperplasia, and hirsutism were more frequent with cyclosporine treatment.\n The significant reduction in the incidence of episodes of allograft rejection observed with tacrolimus therapy may have important long-term implications given the prognostic influence of rejection on graft survival.", "In previous comparative studies tacrolimus was superior to the standard formulation of ciclosporin in preventing acute rejection after renal transplantation. We have compared the microemulsion formulation of ciclosporin with tacrolimus in a multicentre randomised trial.\n The 6-month open study involved 560 patients in 50 European centres. 287 patients were randomly assigned tacrolimus and 273 ciclosporin microemulsion plus azathioprine and corticosteroids. The initial oral daily doses were 0.30 mg/kg for tacrolimus and 8-10 mg/kg for ciclosporin. The primary endpoint was the proportion of patients with biopsy-proven acute rejection and the time to this event.\n The two study groups were similar in terms of baseline characteristics. Three patients did not receive study treatment or did not undergo transplantation (one tacrolimus, two ciclosporin). The rate of biopsy-confirmed acute rejection was significantly lower with tacrolimus than with ciclosporin microemulsion (56 patients [19.6%] vs 101 [37.3%]; 17.7% difference [95% CI 10.3-25.1]; p<0.0001). Biopsy-confirmed corticosteroid-resistant rejection was also significantly lower with tacrolimus (27 [9.4%] vs 57 [21.0%]; 11.6% difference [5.7-17.5]; p<0.0001). Cross-over between therapies because of biopsy-proven rejection was judged necessary in one of 286 (0.3%) tacrolimus-group patients and 27 of 271 (10.0%) ciclosporin-group patients (p<0.0001). There were no significant differences in survival of patients or grafts or in renal function. The overall frequency of adverse events was similar in the two groups, though hypertension and hypercholesterolaemia were more common in the ciclosporin group and tremor and hypomagnesaemia were more frequent in the tacrolimus group.\n Tacrolimus was significantly more effective than ciclosporin microemulsion in preventing acute rejection after renal transplantation and had a superior cardiovascular-risk profile.", "The optimal maintenance immunosuppressive regimen after lung transplantation is uncertain.\n We conducted a randomized controlled trial of tacrolimus versus cyclosporine in combination with azathioprine and prednisone after lung transplantation. Ninety adults were randomized to tacrolimus (n = 44) or cyclosporine (n = 46). The primary end point was a composite of a cumulative acute rejection A score of 3 or higher, a cumulative lymphocytic bronchitis B score of 4 or higher, or the onset of bronchiolitis obliterans syndrome (BOS) stage 0-p.\n Recipients randomized to cyclosporine were significantly more likely to develop the primary end point than those randomized to tacrolimus. During the study period, the primary end point developed in 39 of 46 cyclosporine subjects compared with 24 of 44 tacrolimus subjects (p = 0.002); acute rejection or lymphocytic bronchitis end points developed in 29 of 46 cyclosporine subjects compared with 18 of 44 tacrolimus subjects (p = 0.036). Furthermore, BOS stage 0-p was more likely to develop in the cyclosporine group than in the tacrolimus group, but this was not statistically significant (log-rank p = 0.1). In addition, there was a trend to a higher incidence of diabetes among those in the tacrolimus group, but there was no significant difference in graft survival or the total number of infections, or in the incidence of hypertension, chronic kidney disease, or cancer between the 2 groups.\n Tacrolimus is associated with a lower burden of acute rejection and lymphocytic bronchitis and a trend to a greater freedom from BOS stage 0-p than cyclosporine after lung transplantation.", "Many reports of successful early withdrawal of regular maintenance steroids in transplant recipients have appeared in recent years. The question now arises whether, in the current age of powerful nonsteroidal immunosuppressants such as Neoral and Tacrolimus, routine administration of steroids posttransplant is necessary at all. This single center pilot study reports on the feasibility, safety, and efficacy of single agent immunosuppression \"ab initio\" with either Neoral or Tacrolimus, and no routine or maintenance steroids.\n A total of 64 adult patients receiving first liver grafts for a variety of indications were randomized to receive either Neoral 5 mg/kg BDS or Tacrolimus 0.05 mg/kg BDS orally. Liver biopsies were performed on postoperative days 5 and 10, and whenever else clinically indicated. Rejection episodes were treated with 1.0 g of Methylprednisolone daily for 3 consecutive days. A further episode of rejection after two courses of Methylprednisolone was considered to be monotherapy failure, and consequently other immunosuppressive agents, usually Prednisolone 1 mg/kg/day, was started on a regular basis, tapering slowly.\n Actuarial 1 year survival was 85% for Tacrolimus patients, and 78% for Neoral patients (P = NS), with 80% for Tacrolimus and 73.5% for Neoral at 30 months. Graft survival at 1 and 2.5 years was 73 and 62% for Tacrolimus and Neoral, respectively (P = NS). Two-thirds of patients in both groups showed biopsy evidence of acute cellular rejection. Rejection severity measured by a histological scoring system was similar for both patient groups. Additional longterm immunosuppressive therapy was necessary in 36% of patients receiving Neoral, compared with 13% of Tacrolimus patients (P = NS). No graft was lost on account of acute or chronic rejection. Short-term pulse steroid therapy to treat acute rejection was necessary for 60% of Tacrolimus patients and 40% of Neoral patients.\n Tacrolimus or Neoral monotherapy after liver transplantation provides adequate immunosuppression for 87% of Tacrolimus patients and 64% of Neoral patients. In this study, 33% of patients in both groups showed no evidence of acute rejection, either clinically, biochemically or histologically, and were not exposed to steroids at any time. Evaluation of the long-term morbidity related to the side effects of the immunosuppressants given as monotherapy, for example, renal impairment and posttransplant lymphoproliferative disorder, and the effect on recurrent viral hepatitis in the graft, would be suitable areas for further study.", "Cyclosporine (INN: ciclosporin) A or tacrolimus have been used mostly in combination with azathioprine as primary immunosuppression after lung transplantation. Benefit or risk deriving from the combination with mycophenolate mofetil are yet unknown.\n In a prospective, 2-center, open randomized trial, the combination of cyclosporine A, mycophenolate mofetil, and steroids was compared with tacrolimus, mycophenolate mofetil, and steroids as primary therapy after primary lung transplantation. All patients underwent induction therapy with rabbit antithymocyte globulin for 3 days. The 2 groups were compared with regard to patient survival, freedom from acute rejection, bronchiolitis obliterans, infectious episodes, and side effects.\n Between September 1997 and April 1999, 74 lung transplant recipients were randomized to receive either cyclosporine A (n = 37) or tacrolimus (n = 37). Groups were comparable with regard to age, sex, transplant procedure, and cytomegalovirus match. Mean follow-up was 507 +/- 258 and 508 +/- 248 days, respectively. Six- and 12-month survival was similar in both groups (89% vs 84% and 82% vs 71%, respectively; P =.748 at 12 months). Two patients from the cyclosporine A group were retransplanted. Freedom from acute rejection at 6 and 12 months was comparable between groups (46% vs 51% and 35% vs 46%, respectively; P =.774 at 12 months). The mean number of treated acute rejection episodes per 100 patient-days was higher in the cyclosporine A than in the tacrolimus group, but the difference was not statistically significant (0.32 +/- 0.42 vs 0.22 +/- 0.30, respectively; P =.097). Four patients from the cyclosporine A group had to be switched to tacrolimus to control ongoing rejection, whereas no patient from the tacrolimus group had to be switched to cyclosporine A. There was a trend toward more infections (0.7 +/- 0.36 vs 0.55 +/- 0.31, P =.059) in the cyclosporine A group. New-onset diabetes mellitus was observed in the tacrolimus group only (11% vs 0%, P =.151), whereas there was a higher incidence of hypertension (60% vs 11%, P =.03) in the cyclosporine A group.\n This 2-center, prospective randomized study showed high immunosuppressive potency of both cyclosporine A and tacrolimus in combination with mycophenolate mofetil. No significant difference in incidence of acute rejection was observed between the 2 groups. Moreover, survival and incidence of infection were similar. Incidence of drug-related adverse events were similar, yet their spectrum was different.", "Calcineurin inhibitors are the most commonly used immunosuppressive drugs in liver transplantation, but the optimum initial immunosuppression regimen is not known. The aim of our study was to compare tacrolimus with microemulsified ciclosporin, in a regimen with standardised concomitant immunosuppressive therapy.\n In all liver transplant centres in the UK and Republic of Ireland, 606 patients undergoing a first orthotopic liver transplantation were randomly assigned open-label tacrolimus or microemulsified ciclosporin. Primary outcome was the combined frequency (whichever occurred first) of death, retransplantation, or treatment failure for immunological reasons, analysed by intention to treat.\n 96% of patients received the treatment allocated to them. The primary outcome was reached in 62 (21%) of 301 patients in the tacrolimus group versus 99 (32%) of 305 allocated microemulsified ciclosporin (relative risk 0.63 [95% CI 0.48-0.84], p=0.001; time-to-event analysis log-rank test p=0.002): deaths (50 [17%] vs 72 [24%]); retransplantations (11 [4%] vs 31 [10%]) treatment failure for immunological reasons (6 [2%] vs 12 [4%]). The relative risk for the composite outcome was in favour of tacrolimus. The main causes of death in both trial groups were sepsis and multiple organ failure (31 [10%] vs 30 [10%]), and the main cause for retransplantation was hepatic artery thrombosis (6 [2%] vs 17 [6%]). Renal dysfunction and the need for antihypertensive therapy were much the same in both groups. Tacrolimus was more diabetogenic.\n Clinical outcome at 1 year was better with tacrolimus-based immunosuppression than with microemulsified ciclosporin during the first year after liver transplantation. Tacrolimus should be the first choice of calcineurin inhibitor for patients receiving their first liver graft." ]

[ "Despite the demonstrated efficacy of psychosocial approaches to schizophrenia treatment that include a psychoeducational component, such as illness management, the implementation of these approaches into routine mental health treatment has been slow. The authors sought to examine the efficacy of a comprehensive, modularized, psychoeducational program called Team Solutions, which was designed to educate patients with major mental illnesses about their illness and how to manage it. Team Solutions was chosen for study because it is available over the Internet and other venues at no cost and is used by mental health agencies across the United States and Canada.\n Seventy-one persons with schizophrenia or schizoaffective disorder from three day treatment settings participated in this randomized, single-blind study. Participants were randomly assigned to attend one of two interventions: the Team Solutions intervention, which consisted of participating in a 24-week psychoeducational group focused on illness management, or treatment as usual.\n For participants who attended the experimental group, significant improvement was observed in knowledge about schizophrenia. In addition, client satisfaction was high. However, no changes were observed in symptoms or functioning.\n Results indicated that participation in the Team Solutions psychoeducational group improved participants' knowledge. However, participation in the program did not demonstrate superiority over treatment as usual with respect to secondary and tertiary outcomes, such as symptom severity, treatment adherence, and global functioning.", "Research evidence supports the efficacy of cognitive-behavioral therapy in the treatment of drug-refractory positive symptoms of schizophrenia. Although the cumulative evidence is strong, early controlled trials showed methodological limitations.\n A randomized controlled design was used to compare the efficacy of manualized cognitive-behavioral therapy developed particularly for schizophrenia with that of a nonspecific befriending control intervention. Both interventions were delivered by 2 experienced nurses who received regular supervision. Patients were assessed by blind raters at baseline, after treatment (lasting up to 9 months), and at a 9-month follow-up evaluation. Patients continued to receive routine care throughout the study. An assessor blind to the patients' treatment groups rated the technical quality of audiotaped sessions chosen at random. Analysis was by intention to treat.\n Ninety patients received a mean of 19 individual treatment sessions over 9 months, with no significant between-group differences in treatment duration. Both interventions resulted in significant reductions in positive and negative symptoms and depression. At the 9-month follow-up evaluation, patients who had received cognitive therapy continued to improve, while those in the befriending group did not. These results were not attributable to changes in prescribed medication.\n Cognitive-behavioral therapy is effective in treating negative as well as positive symptoms in schizophrenia resistant to standard antipsychotic drugs, with its efficacy sustained over 9 months of follow-up." ]

[ "The purpose of this study was to examine the effects of a probiotic supplement during 4 mo of winter training in men and women engaged in endurance-based physical activities on incidence of upper respiratory-tract infections (URTIs) and immune markers. Eighty-four highly active individuals were randomized to probiotic (n = 42) or placebo (n = 42) groups and, under double-blind procedures, received probiotic (PRO: Lactobacillus casei Shirota [LcS]) or placebo (PLA) daily for 16 wk. Resting blood and saliva samples were collected at baseline and after 8 and 16 wk. Weekly training and illness logs were kept. Fifty-eight subjects completed the study (n = 32 PRO, n = 26 PLA). The proportion of subjects on PLA who experienced 1 or more weeks with URTI symptoms was 36% higher than those on PRO (PLA 0.90, PRO 0.66; p = .021). The number of URTI episodes was significantly higher (p < .01) in the PLA group (2.1 ± 1.2) than in the PRO group (1.2 ± 1.0). Severity and duration of symptoms were not significantly different between treatments. Saliva IgA concentration was higher on PRO than PLA, significant treatment effect F(1, 54) = 5.1, p = .03; this difference was not evident at baseline but was significant after 8 and 16 wk of supplementation. Regular ingestion of LcS appears to be beneficial in reducing the frequency of URTI in an athletic cohort, which may be related to better maintenance of saliva IgA levels during a winter period of training and competition.", "A randomised, double-blind, placebo-controlled study was conducted to determine whether probiotics might be effective in reducing the risk of infections in infancy. Infants requiring formula before the age of 2 months were recruited from community well-baby clinics. Infant formula supplemented with the probiotics Lactobacillus rhamnosus GG and Bifidobacterium lactis Bb-12 or placebo was administered daily until the age of 12 months. Incidence of early infections (before the age of 7 months) and incidence of recurrent (three or more) infections during the first year of life were recorded as the main outcome measures of the study. During the first 7 months of life, seven out of thirty-two (22 %) infants receiving probiotics and twenty out of forty (50 %) infants receiving placebo experienced acute otitis media (risk ratio (RR) 0.44 (95 % CI 0.21, 0.90); P = 0.014) and antibiotics were prescribed for ten out of thirty-two (31 %) infants receiving probiotics and twenty-four out of forty (60 %) infants receiving placebo (RR 0.52 (95 % CI 0.29, 0.92); P = 0.015). During the first year of life, nine out of thirty-two (28 %) infants receiving probiotics and twenty-two out of forty (55 %) infants receiving placebo encountered recurrent respiratory infections (RR 0.51 (95 % CI 0.27, 0.95); P = 0.022). These data suggest that probiotics may offer a safe means of reducing the risk of early acute otitis media and antibiotic use and the risk of recurrent respiratory infections during the first year of life. Further clinical trials are warranted.", "Recurrent upper respiratory tract infections (URTIs) are common illnesses in young children. As the immunoactive bacterial extract OM-85 has been shown to prevent these infections in both adults and children, the aim of the present trial was to investigate further its efficacy and safety in infection-prone children.\n This is a randomized, double-blind, placebo-controlled, multicenter study with OM-85 in 232 patients aged 36 to 96 months with recurrent URTIs. Treatment was one capsule daily during month 1 and during 10 days in months 3 to 5. URTI was defined by the presence of at least two of the following: rhinitis, pharyngitis, cough, hoarseness, temperature > or = 38.5 degrees C, or URTI-related prescription of an antibiotic.\n OM-85-treated patients had a lower rate of URTIs (p < 0.05). The cumulated difference in URTIs between the two groups reached - 0.40 URTIs per patient in 6 months, corresponding to a 16% reduction in the active-treatment group with respect to placebo. The largest difference was observed in the patients having had three or more URTIs during the study period; odds ratios for three or more URTIs were 0.51 (95% confidence interval, 0.29 to 0.91) and 0.65 (95% confidence interval, 0.37 to 1.11) after 5 months and 6 months, respectively. The difference between OM-85 and placebo was independent of age but was more important in patients reporting a larger number of URTIs in the previous year. Patients' global assessment showed improvement in comparison to the previous season in the majority of the cases (OM-85, 78.4% of cases; placebo, 75.5%); however, there were more cases reporting worsening with placebo (6.4% vs 0.9%; p = 0.05).\n OM-85 treatment significantly reduced the rate of URTIs, particularly in children with a history of frequent URTIs. Safety and tolerance of test medication were good, comparable to placebo.", "To examine whether probiotics would reduce the occurrence or duration of acute otitis media (AOM), or the nasopharyngeal carriage of otitis pathogens in otitis-prone children.\n During this double-blind, placebo-controlled, randomised, 24-week intervention, 309 otitis-prone children (10 months-6 years) consumed either one probiotic capsule (Lactobacillus rhamnosus GG and LC705, Bifidobacterium breve 99 and Propionibacterium freudenreichii JS) (n=155) or placebo (n=154) daily. Clinical examinations were carried out and nasopharyngeal samples taken three times. Parents recorded the symptoms of upper respiratory infection (URI) in a diary.\n Probiotic treatment did not reduce the occurrence (probiotic vs. placebo: 72% vs. 65%, OR=1.48, 95% CI 0.87-2.52, p=n.s.) or the recurrence ( three) of AOM episodes (18% vs. 17%, OR=1.04, 95% CI 0.55-1.96, p=n.s.). The median duration of AOM episodes was 5.6 (IQR 3.5-9.4) vs. 6.0 (IQR 4.0-10.5) days, respectively (p= n.s.). There was a tendency showing a reduction in the occurrence of recurrent (4 to 6) respiratory infections in the probiotic group (OR for 4 URIs: 0.56, 95%CI 0.31-0.99, p=0.046; OR for 6 URIs: 0.59, 95% CI 0.34 to 1.03, p=n.s.). Probiotics did not affect the carriage of Streptococcus pneumoniae or Haemophilus influenzae, but increased the prevalence of Moraxella catarrhalis (OR=1.79, 95% CI 1.06-3.00, p=0.028).\n Probiotics did not prevent the occurrence of AOM or the nasopharyngeal carriage of otitis pathogens in otitis-prone children. A tendency showing a reduction in recurrent respiratory infections must be confirmed in further studies.", "Standard therapies for antibiotic-associated diarrhea (AAD) and Clostridium difficile-associated diarrhea (CDAD) have limited efficacy. Probiotic prophylaxis is a promising alternative for reduction of AAD and CDAD incidence.\n In this single-center, randomized, double-blind, placebo-controlled dose-ranging study, we randomized 255 adult inpatients to one of three groups: two probiotic capsules per day (Pro-2, n=86), one probiotic capsule and one placebo capsule per day (Pro-1, n=85), or two placebo capsules per day (n=84). Each probiotic capsule contained 50 billion c.f.u. of live organisms (Lactobacillus acidophilus CL1285 +Lactobacillus casei LBC80R Bio-K+ CL1285). Probiotic prophylaxis began within 36 h of initial antibiotic administration, continued for 5 days after the last antibiotic dose, and patients were followed for an additional 21 days.\n Pro-2 (15.5%) had a lower AAD incidence vs. Pro-1 (28.2%). Each probiotic group had a lower AAD incidence vs. placebo (44.1%). In patients who acquired AAD, Pro-2 (2.8 days) and Pro-1 (4.1 days) had shorter symptom duration vs. placebo (6.4 days). Similarly, Pro-2 (1.2%) had a lower CDAD incidence vs. Pro-1 (9.4%). Each treatment group had a lower CDAD incidence vs. placebo (23.8%). Gastrointestinal symptoms were less common in the treatment groups vs. placebo and in Pro-2 vs. Pro-1.\n The proprietary probiotic blend used in this study was well tolerated and effective for reducing risk of AAD and, in particular, CDAD in hospitalized patients on antibiotics. A dose-ranging effect was shown with 100 billion c.f.u., yielding superior outcomes and fewer gastrointestinal events compared to 50 billion c.f.u. (ClinicalTrials.gov number NCT00958308).", "Acute infectious diarrhea is a major cause of childhood morbidity and economic burden for families. We evaluate the clinical, microbiologic, and immunologic effects of probiotics in acute infectious diarrhea.\n Children (n = 304) aged 3 months to 6 years hospitalized for acute diarrhea were randomized to receive Bio-three (a mixture of Bacillus mesentericus, Enterococcus faecalis, and Clostridium butyricum) or placebo orally 3 times daily for 7 days. Fecal samples were homogenized for bacterial culture and blood cells were isolated for cell culture and cytokine analysis. This study is registered (NCT00463190).\n The mean duration of diarrhea after start of therapy was 60.1 hours in the probiotics group versus 86.3 hours in the placebo group (P = 0.003). Hospital stay was shorter in the probiotics group than in the placebo group (P = 0.009). Counts of Bifidobacteria and Lactobacillus species were elevated in stool culture of the probiotics (Bio-three) group. IL-10 was increased in the serum and supernatants of cell culture in the probiotics group, and tumor necrosis factor-alpha values were down-regulated. Interferon- gamma and IL-12 were mildly elevated in the probiotics group, compared with the placebo group.\n This probiotics mixture reduced the severity of diarrhea and length of hospital stay in children with acute diarrhea. In addition to restoring beneficial intestinal flora, probiotics may enhance host protective immunity such as down-regulation of pro-inflammatory cytokines and up-regulation of anti-inflammatory cytokines.", "Ulcerative colitis (UC) is an acute and chronic inflammatory disease of the large bowel with unknown aetiology. The immune response against normal commensal microorganisms is believed to drive inflammatory processes associated with UC. Therefore, modulation of bacterial communities on the gut mucosa, through the use of probiotics and prebiotics, may be used to modify the disease state.\n A synbiotic was developed for use in UC patients combining a probiotic, Bifidobacterium longum, isolated from healthy rectal epithelium, and a prebiotic (Synergy 1), a preferential inulin-oligofructose growth substrate for the probiotic strain. Treatment was employed in a double blinded randomised controlled trial using 18 patients with active UC for a period of one month. Clinical status was scored and rectal biopsies were collected before and after treatment, and transcription levels of epithelium related immune markers were measured.\n Sigmoidoscopy scores (scale 0-6) were reduced in the test group (start 4.5 (1.4), end 3.1 (2.5)) compared with placebo (start 2.6 (2.1), end 3.2 (2.2)) (p=0.06). mRNA levels for human beta defensins 2, 3, and 4, which are strongly upregulated in active UC, were significantly reduced in the test group after treatment (p=0.016, 0.038, and 0.008, respectively). Tumour necrosis factor alpha and interleukin 1alpha, which are inflammatory cytokines that drive inflammation and induce defensin expression, were also significantly reduced after treatment (p=0.018 and 0.023, respectively). Biopsies in the test group had reduced inflammation and regeneration of epithelial tissue.\n Short term synbiotic treatment of active UC resulted in improvement of the full clinical appearance of chronic inflammation in patients receiving this therapy.", "Antibiotic-associated diarrhea (AAD) and Clostridium difficile-associated diarrhea (CDAD) are common complications of antibiotic use. Probiotics were effective in preventing AAD and CDAD in several randomized controlled trials. This study was aimed at testing the effect of Saccharomyces boulardii on the occurrence of AAD and CDAD in hospitalized patients.\n A single-center, randomized, double-blind, placebo-controlled, parallel-group trial was performed. Patients being prescribed antibiotics or on antibiotic therapy for <48 h were eligible. Exclusion criteria were ongoing diarrhea, recent assumption of probiotics, lack of informed consent, inability to ingest capsules, and severe pancreatitis. Patients received a capsule containing S. boulardii or an indistinguishable placebo twice daily within 48 h of beginning antibiotic therapy, continued treatment for 7 days after antibiotic withdrawal, and were followed for 12 weeks after ending antibiotic treatment.\n Of 562 consecutive eligible patients, 275 patients aged 79.2 ± 9.8 years (134 on placebo) were randomized and 204 aged 78.4 ± 10.0 years (98 on placebo) completed the follow-up. AAD developed in 13.3% (13/98) of the patients receiving placebo and in 15.1% (16/106) of those receiving S. boulardii (odds ratio for S. boulardii vs. placebo, 1.16; 95% confidence interval (CI), 0.53-2.56). Five cases of CDAD occurred, 2 in the placebo group (2.0%) and 3 in the probiotic group (2.8%; odds ratio for S. boulardii vs. placebo, 1.40; 95% CI, 0.23-8.55). There was no difference in mortality rates (12.7% vs. 15.6%, P=0.60).\n In elderly hospitalized patients, S. boulardii was not effective in preventing the development of AAD.", "Evidence exists for the pathogenic role of the enteric flora in inflammatory bowel disease. Probiotics contain living microorganisms which exert health effects on the host. We compared the efficacy in maintaining remission of the probiotic preparation Escherichia coli Nissle 1917 and established therapy with mesalazine in patients with ulcerative colitis.\n In total, 327 patients were recruited and assigned to a double blind, double dummy trial to receive either the probiotic drug 200 mg once daily (n = 162) or mesalazine 500 mg three times daily (n = 165). The study lasted for 12 months and patients were assessed by clinical and endoscopic activity indices (Rachmilewitz) as well as by histology. The primary aim of the study was to confirm equivalent efficacy of the two drugs in the prevention of relapses.\n The per protocol analysis revealed relapses in 40/110 (36.4%) patients in the E coli Nissle 1917 group and 38/112 (33.9%) in the mesalazine group (significant equivalence p = 0.003). Subgroup analyses showed no differences between the treatment groups in terms of duration and localisation of disease or pretrial treatment. Safety profile and tolerability were very good for both groups and were not different.\n The probiotic drug E coli Nissle 1917 shows efficacy and safety in maintaining remission equivalent to the gold standard mesalazine in patients with ulcerative colitis. The effectiveness of probiotic treatment further underlines the pathogenetic significance of the enteric flora.", "To investigate the clinical effect of treatment with Lactobacillus acidophilus La-5 and Bifidobacterium animalis subsp. lactis BB-12 (Probio-Tec AB-25) to maintain remission in patients with ulcerative colitis.\n Patients with left-sided ulcerative colitis in remission - including proctitis and at least one relapse within the last year were randomised (2:1) in a double-blind placebo-controlled study to Probio-Tec AB-25 or placebo for 52 weeks. The patients were evaluated clinically, endoscopically and histologically at entry and if relapsing. No other medication for ulcerative colitis than the study drug was allowed during the study. Primary endpoint was maintenance of clinical remission, secondary endpoints comparisons of days to relapse, and safety and tolerability of the study drug. The concentrations of the probiotic bacterial strains in stool were analysed in a subset of patients.\n Thirty-two patients were randomised. Twenty patients received Probio-Tec AB-25 and twelve patients received placebo. Five patients (25%) in the Probio-Tec AB-25 group and one patient (8%) in the placebo group maintained remission after 1 year of treatment (p=0.37). The median time to relapse was 125.5days (range 11-391 days) in the probiotic group and 104 days (range 28-369 days) in the placebo group respectively, (p=0.683). Probio-Tec AB-25 was overall well tolerated.\n In this small randomised placebo-controlled trial no significant clinical benefit of Probio-Tec AB-25 could be demonstrated in comparison with placebo for maintaining remission in patients with left-sided ulcerative colitis. A difference may be achieved in larger studies, but the clinical significance of this would be questionable. This study was registered in ClinicalTrial.gov (NCT00268164).\n Copyright © 2010 European Crohn's and Colitis Organisation. Published by Elsevier B.V. All rights reserved.", "Thirty patients with distal ulcerative colitis in remission (17 proctitis, 13 proctosigmoiditis) were randomly given either 5-aminosalicylic acid (5-ASA) or placebo suppositories, 400 mg bid. During the 1-yr follow-up, patients were assessed clinically every month, and flexible sigmoidoscopy with a rectal pinch biopsy specimen and laboratory data were carried out every 3 months. Two patients in the 5-ASA group chose to withdraw from the study, one relapsed, and 12 remained in remission. In the placebo group, one patient chose to withdraw, 11 relapsed, and three remained in remission. The cumulative remission rate at the 12th month was 92% in the 5-ASA group and 21% in the placebo group. Log rank test showed a significant difference in the relapse rate between the two groups (chi 2 = 14.26, p less than 0.001). No side effects were observed. We conclude that 5-ASA in suppository form (800 mg/day), administered for 1 yr, is safe and effective in maintaining remission of distal ulcerative colitis.", "It has been suggested that probiotics can reduce the overgrowth of pathogens in the bowels of preterm infants and contribute to the reduction of the incidence of nosocomial infections in neonatal intensive care units (NICUs). The purpose of this study was to evaluate the effectiveness of Lactobacillus GG supplementation in reducing the incidence of urinary tract infections (UTIs), bacterial sepsis and necrotizing enterocolitis (NEC) in preterm infants.\n A double-blind study was conducted in 12 Italian NICUs. Newborn infants with a gestational age <33 weeks or birthweight <1,500 g were randomized to receive standard milk feed supplemented with Lactobacillus GG (Dicoflor), Dicofarm, Rome, Italy) in a dose of 6 x 10(9) colony-forming units (cfu) once a day until discharge, starting with the first feed or placebo.\n Five hundred eighty-five patients were studied. The probiotics group (n = 295) and the placebo group (n = 290) exhibited similar clinical characteristics. The duration of Lactobacillus GG and placebo supplementation was 47.3 +/- 26.0 and 48.2 +/- 24.3 days, respectively. Although UTIs (3.4 vs. 5.8%) and NEC (1.4 vs. 2.7%) were found less frequently in the probiotic group compared to the control group, these differences were not significant. Bacterial sepsis was more frequent in the probiotics group (4.4%, n = 11) than in the placebo group (3.8%, n = 9), but the difference was not significant.\n Seven days of Lactobacillus GG supplementation starting with the first feed is not effective in reducing the incidence of UTIs, NEC and sepsis in preterm infants. Further studies are required to confirm our results in lower birthweight populations.\n Copyright 2002 S. Karger AG, Basel", "The increase in allergic diseases is attributed to a relative lack of microbial stimulation of the infantile gut immune system. Probiotics, live health-promoting microbes, might offer such stimulation.\n We studied the effect of a mixture of 4 probiotic bacterial strains along with prebiotic galacto-oligosaccharides in preventing allergic diseases.\n We randomized 1223 pregnant women carrying high-risk children to use a probiotic preparation or a placebo for 2 to 4 weeks before delivery. Their infants received the same probiotics plus galacto-oligosaccharides (n = 461) or a placebo (n = 464) for 6 months. At 2 years, we evaluated the cumulative incidence of allergic diseases (food allergy, eczema, asthma, and allergic rhinitis) and IgE sensitization (positive skin prick test response or serum antigen-specific IgE level >0.7 kU/L). Fecal bacteria were analyzed during treatment and at age 2 years.\n Probiotic treatment compared with placebo showed no effect on the cumulative incidence of allergic diseases but tended to reduce IgE-associated (atopic) diseases (odds ratio [OR], 0.71; 95% CI, 0.50-1.00; P = .052). Probiotic treatment reduced eczema (OR, 0.74; 95% CI, 0.55-0.98; P = .035) and atopic eczema (OR, 0.66; 95% CI, 0.46-0.95; P = .025). Lactobacilli and bifidobacteria more frequently (P < .001) colonized the guts of supplemented infants.\n Probiotic treatment showed no effect on the incidence of all allergic diseases by age 2 years but significantly prevented eczema and especially atopic eczema. The results suggest an inverse association between atopic diseases and colonization of the gut by probiotics.\n The prevention of atopic eczema in high-risk infants is possible by modulating the infant's gut microbiota with probiotics and prebiotics." ]

[ "Term pregnancies following surgery on patients with distal tubal obstruction have been disappointingly few. There has been continuing interest in whether postoperative hydrotubation increases the rate of pregnancy following salpingoneostomy and fimbrioplasty. This hypothesis was tested in a prospective, randomized, multicenter clinical trial. Patients with no infertility factors other than distal fimbrial disease were randomly assigned to either a control group (no hydrotubation, n = 86) or one of two treatment groups (hydrotubation with lactated Ringer's solution, n = 60, or lactated Ringer's solution containing hydrocortisone, n = 60). The statistical evaluation of differences among treatment groups was based on the Cox Proportional Hazards Model, which allows for covariable adjustment and for the inclusion of all patients regardless of the length of follow-up. A significant difference in the live birth rate could not be demonstrated among the groups studied (P = 0.36). The probability of a successful live birth among women treated by hydrotubation with hydrocortisone was about one-half that of the other groups (P = 0.12). Patients with moderate and severe disease had a substantially lower probability of pregnancy than those with mild disease (P = 0.013 and P = 0.0016, respectively). The probability of pregnancy increased somewhat as the number of previous pregnancies increased (P = 0.12). In this clinical trial, a beneficial effect following postoperative hydrotubation could not be demonstrated.", "To evaluate the fertility outcome after laparoscopic surgery for ectopic pregnancy.\n A randomized trial versus laparotomy was performed between May 1987 and June 1989.\n The study was conducted in a clinical university center, the Sahlgrens Hospital.\n A group of 105 patients with tubal pregnancy were stratified with regard to risk determinants and age and randomized to laparoscopy or laparotomy. Eighty-seven patients who desired pregnancy were evaluated for subsequent fertility outcome.\n Linear salpingotomy was performed in both surgical groups.\n We evaluated the fertility outcome after laparoscopic salpingotomy for comparison with the outcome after laparotomy.\n There was no difference between the groups in the overall fertility outcome. A substantially higher proportion of patients in the laparotomy group were subjected to adhesiolysis performed at a second-look laparoscopy.\n The fertility prospects are not impaired by laparoscopic surgery. Adhesiolysis at a second-look laparoscopy, especially after laparotomy, might be beneficial in selected cases and may serve to improve subsequent fertility.", "To evaluate and compare the clinical impact of proximal tubal occlusion and salpingectomy when performed before IVF in patients with hydrosalpinges.\n Prospective randomized study.\n Assisted reproduction unit in an obstetrics and gynecology department in a university hospital in Greece as well as assisted reproduction unit in an urban clinic in a major city in Greece.\n One hundred fifteen patients with unilateral or bilateral hydrosalpinges who were candidates for IVF treatment.\n Laparoscopic proximal tubal occlusion, laparoscopic salpingectomy, controlled ovarian hyperstimulation, IVF, and embryo transfer.\n Implantation rate, clinical-pregnancy rate, ongoing-pregnancy rate, abortion rate, and ectopic-pregnancy rate.\n Patients who underwent proximal tubal occlusion before IVF demonstrated significantly increased implantation, clinical-pregnancy, and ongoing-pregnancy rates compared with those with no surgical intervention and demonstrated implantation, clinical-pregnancy, and ongoing-pregnancy rates comparable to those who underwent salpingectomy.\n Proximal tubal occlusion, when performed in women with unilateral or bilateral hydrosalpinges before their IVF treatment, represents a potentially beneficial surgical procedure, increasing significantly the chances for successful implantation and for clinical and ongoing pregnancy. Proximal tubal occlusion may be viewed as a valid alternative when salpingectomy is technically difficult or not feasible.", "An examination was made of the possibility that 100 to 200 ml of intraperitoneal 32% dextran 70 and/or 0.5% hydrocortisone sodium succinate (randomized independently with similar volumes of Ringer's lactate solution) might help to lessen the postoperative formation of adhesions among patients undergoing surgical procedures for peritubal adhesions (n = 76), endometriosis (n = 27), or midtubal occlusion (n = 61). Patients in the first two groups who were given intraperitoneal corticosteroids were also given systemic steroids. Nonparametric comparison of median adhesion scores at operation and at subsequent laparoscopy showed that there was a poorer outcome with dextran than when dextran was not used in every subgroup except one (repeat salpingolysis after previous operation for adhesions), including first operations for adnexal adhesions (Mann-Whitney U = 200, m = 23, n = 26; p less than 0.05). The probability was small (p beta less than 0.002) that an important beneficial effect of dextran was overlooked. Systemic corticosteroids were associated with a consistent trend toward improved outcome, especially in patients who initially had few or no adhesions, such as those operated on for endometriosis (U = 2, m = 7, n = 4; p less than 0.025), but among patients with tubal resections and anastomoses with adnexal adhesions the use of intraperitoneal hydrocortisone alone was associated with a worse outcome (U = 15, m = 12, n = 8; p less than 0.02). Life-table analysis of the accumulating probability of pregnancy showed that no significant difference resulted from adjunct use in any group. The conclusion is that no empiric basis supports the use of intraperitoneal 32% dextran 70 or 0.5% hydrocortisone in the attempt to prevent peritoneal adhesions, but further investigations on the systemic administration of corticosteroids to decrease the formation of adhesions would be useful.", "To compare single dose systemic methotrexate (50 mg/m2) with laparoscopic surgery for the treatment of unruptured tubal pregnancy.\n An open, pragmatic, prospective randomised trial.\n Departments of obstetrics and gynaecology at three hospitals in Auckland, New Zealand.\n Clinically stable women with an unruptured tubal pregnancy diagnosed by transvaginal ultrasound and quantitative serum beta-hCG measurement. Inclusion criteria included a serum beta-hCG concentration < 5,000 IU/L, and a tubal pregnancy of < 3.5 cm diameter.\n Treatment success, physical and psychological functioning, side effects, and subsequent ipsilateral tubal patency.\n Two hundred and eighteen women with ectopic pregnancies were seen at the three hospitals. 79 women (36% eligibility rate) were eligible for trial entry and 62 women (78% recruitment rate) were recruited. Twenty-six of the 28 women (93%) randomised to laparoscopic surgery required no further treatment, compared with 22 of the 34 women (65%) randomised to methotrexate (95% CI of difference in success rate 10 - 47%; P < 0.01). Two women (7%) in the laparoscopic surgery group had persistent trophoblast. Nine women (26%) in the methotrexate group required more than one dose of methotrexate and five women (15%) underwent laparoscopy during follow up. In the laparoscopy group three women (11%) had negative laparoscopies and two women (7%) had were found to have a ruptured fallopian tube at the time of surgery. Women treated with methotrexate had significantly better objective physical functioning scores but there were no differences in any other psychological outcomes. Women treated with methotrexate experienced greater and more prolonged vaginal bleeding. The likelihood of methotrexate treatment failure was greater at higher serum beta-hCG concentrations. Ipsilateral tubal patency rates were similar in each group.\n This trial shows that in the treatment of tubal pregnancy single dose systemic methotrexate is a less effective treatment than laparoscopic salpingotomy. It is well tolerated, but should only be offered as an alternative to surgery to women who have mild symptoms and present at low serum beta-hCG concentrations. In our population this likely to be no more than a quarter of women presenting with a tubal pregnancy." ]

[ "A minority of cancer survivors develops long-term postsurgical neuropathic pain. Based on evidence that capsaicin, the pungent ingredient in hot chili peppers, might be useful for treating neuropathic pain, we developed the present clinical trial.\n Ninety-nine assessable patients with postsurgical neuropathic pain were entered onto this study. After stratification, patients were to receive 8 weeks of a 0.075% capsaicin cream followed by 8 weeks of an identical-appearing placebo cream, or vice versa. A capsaicin/placebo cream was to be applied to the painful site four times daily. Treatment evaluation was performed by patient-completed weekly questionnaires.\n During the first 8-week study period, the capsaicin-cream arm was associated with substantially more skin burning, skin redness, and coughing (P < .0001 for each). Nonetheless, treatment was stopped for patient refusal or toxicity just as often while patients were receiving the placebo as compared with the capsaicin. The capsaicin cream arm had substantially more pain relief (P = .01) after the first 8 weeks, with an average pain reduction of 53% versus 17%. On completion of the 16-week study period, patients were asked which treatment period was most beneficial. Of the responding patients, 60% chose the capsaicin arm, 18% chose the placebo arm, and 22% chose neither (P = .001).\n A topical capsaicin cream decreases postsurgical neuropathic pain and, despite some toxicities, is preferred by patients over a placebo by a three-to-one margin among those expressing a preference.", "We have completed a 12-week double-blind, placebo-controlled randomized study on the efficacy of the application of capsaicin (CAPS) cream (0.075%) in the treatment of chronic distal painful polyneuropathy. Forty patients were enrolled and 39 completed the study. The 2 limbs were randomly assigned to CAPS or placebo (PLAC). The cream was applied 4 times a day. The first tube contained the active PLAC, methyl nicotinate. In the final 4 weeks (single-blind wash-out phase), PLAC was administered bilaterally. Efficacy was evaluated using the following scales: (1) investigator global, (2) patient global, (3) visual analog (VAS) of pain severity, (4) VAS of pain relief, (5) activities of daily living, and (6) allodynia. Patients were examined at onset and at monthly intervals using a neurologic disability scale, nerve conduction studies, computer-assisted sensory examination for vibration and thermal cooling and warming, QSART (quantitative sudomotor axon reflex test) and quantitative flare response. There was no statistical evidence of efficacy of CAPS cream over PLAC for any of the pain indices. At early time points (1-4 weeks), there were a small number of indices that favored the PLAC. The percent of limbs that improved on the investigator's global scale were 51.3 vs. 53.8 at 4 weeks, 56.4 vs. 64.1 at 8 weeks and 59 vs. 66.7 at 12 weeks for CAPS vs. PLAC; no statistically significant difference was found. All the safety indices showed no difference between sides. We interpret the early hyperalgesia on the CAPS side as being responsible for the better performance of PLAC at early time points. The large percentage of limbs that improved may be a pronounced PLAC response.", "HIV-associated distal sensory polyneuropathy (HIV-DSP) is a painful condition with limited effective treatment. Capsaicin desensitizes cutaneous nociceptors resulting in reduced pain. We report a placebo-controlled study of a high-concentration capsaicin dermal patch (NGX-4010) for the treatment of painful HIV-DSP.\n This double-blind multicenter study randomized 307 patients with painful HIV-DSP to receive NGX-4010 or control, a low-concentration capsaicin patch. After application of a topical anesthetic, NGX-4010 or control was applied once for 30, 60, or 90 minutes to painful areas on the feet. The primary efficacy endpoint was percent change in Numeric Pain Rating Scale (NPRS) from baseline in mean \"average pain for past 24 hours\" scores from weeks 2 to 12.\n A single NGX-4010 application resulted in a mean pain reduction of 22.8% during weeks 2 to 12 as compared to a 10.7% reduction for controls (p = 0.0026). Following a transient treatment-related pain increase, pain was reduced; significant improvement was apparent by week 2 and continued throughout the controlled 12-week observation period. Mean pain reductions in the NGX-4010 30-, 60- and 90-minute groups were 27.7%, 15.9%, and 24.7% (p = 0.0007, 0.287, and 0.0046 vs control). One third of NGX-4010-treated patients reported >or=30% pain decrease from baseline as compared to 18% of controls (p = 0.0092). Self-limited, mild-to-moderate local skin reactions were commonly observed.\n A single NGX-4010 application was safe and provided at least 12 weeks of pain reduction in patients with HIV-associated distal sensory polyneuropathy. These results suggest that NGX-4010 could provide a promising new treatment for painful HIV neuropathy.", "To determine the effectiveness of topical capsaicin cream application on localized pain in the temporomandibular joint (TMJ) area.\n A randomized, double-blind, placebo-controlled study was conducted on 30 patients suffering from unilateral pain in the TMJ area. Patients were randomly divided into experimental and placebo groups; they were instructed to apply 0.025% capsaicin cream or its vehicle to the painful TMJ area 4 times daily for 4 weeks. Subjective parameters of present pain, most severe pain, effect of pain on daily activities, and pain relief were assessed each week on a visual analog scale. Muscle and joint sensitivity to palpation on the painful and contralateral joints and maximal mouth opening (assisted/passive and non-assisted/active) were examined weekly by the same experienced examiner.\n Capsaicin cream produced no statistically significant influence on measured variables when compared to placebo. Both experimental and placebo groups showed statistically significant improvement in most variables during the experiment.\n The factor of time had a major effect in the non-specific improvement of the parameters assessed. The placebo effect played an important role in the treatment of patients with pain in the TMJ area.", "An 8-week double-blind, multicenter, parallel study compared the safety and efficacy of topical capsaicin and oral amitriptyline in patients with painful diabetic neuropathy involving the feet. Two hundred thirty-five patients were randomized to treatment with either capsaicin cream or amitriptyline capsules. Capsaicin-treated patients received inactive capsules, and amitriptyline-treated patients applied vehicle cream. A visual analogue scale of pain intensity and measurements of interference by pain with functional activities were recorded at onset and at 2-week intervals. A visual analogue scale of pain relief and physicians' global evaluation assessed changes in pain status from baseline. Topical capsaicin and oral amitriptyline produced equal and statistically significant improvements in pain over the course of the study. By the end of week 8, 76% of patients in each group experienced less pain, with a mean reduction in intensity of more than 40%. By the end of the study, the interference with daily activities by pain had diminished significantly (P = .001) in both groups, including improvements in sleeping and walking. No systemic side effects were observed in patients treated with topical capsaicin. Most patients receiving amitriptyline experienced at least one systemic side effect, ranging from somnolence (46%) to neuromuscular (23%) and cardiovascular (9%) adverse effects. Topically applied capsaicin is an equally effective but considerably safer alternative to amitriptyline for relief of the pain of diabetic neuropathy.", "Pruritus is a significant symptom among patients receiving hemodialysis. However, its underlying mechanisms remain obscure. Substance P, a neuropeptide, has been implicated in the mediation of pain and some itch sensations. Local application of capsaicin depletes the peripheral neurons of substance P and may block the conduction of pain or pruritus. This study aims to assess the efficacy and safety of capsaicin 0.025% cream in the treatment of hemodialysis-related pruritus and to further explore the underlying pathomechanism. Nineteen hemodialysis patients with idiopathic, moderate (n = 5) to severe (n = 14) pruritus were examined in a double-blind, placebo-controlled, crossover study and 17 of them completed the study. Topical agent of capsaicin or placebo base cream was applied to localized areas of pruritus 4 times a day. The severity of pruritus and treatment-related side effects (cutaneous burning/stinging sensations, dryness, or erythema) were evaluated weekly. The results showed (1) that 14 of 17 patients reported marked relief and 5 of these 14 patients had complete remission of pruritus during capsaicin treatment (Wilcoxon signed-ranks test, 2p < 0.001); (2) capsaicin was significantly more effective than placebo (Mann-Whitney rank sum test, 2p < 0.001) and a prolonged antipruritic effect was observed 8 weeks posttreatment; (3) no serious side effects were noted during the study and (4) there were no significant changes in serum concentrations of albumin, calcium, phosphorus, alkaline phosphatase, or intact parathyroid hormone during the treatment with either capsaicin or placebo. In summary, the present study indicates indirectly that idiopathic pruritus in some patients on maintenance hemodialysis may be transmitted by substance P from the peripheral sensory neurons to the central nervous system. Topical capsaicin with the unique pharmacological effect is demonstrated to markedly improve the pruritus of these patients.", "To establish the effects of topically applied capsaicin on daily activities in patients with painful diabetic neuropathy.\n Investigators at 12 sites enrolled 277 men and women with painful peripheral polyneuropathy and/or radiculopathy in an 8-wk double-blind vehicle-controlled study with parallel randomized treatment assignments. Participants were unresponsive or intolerant to conventional therapy and were experiencing pain that interfered with functional activities and/or sleep. Either 0.075% capsaicin cream or vehicle cream was applied to the painful areas 4 times/day. A visual analogue scale of pain intensity and baseline measurements of the pain's interference with the ability to walk, work, participate in recreational activities, use shoes and socks, sleep, and eat were recorded at onset and at 2-wk intervals. A physician's global evaluation scale assessed changes in pain status from baseline.\n Statistically significant differences are percentage of patients with improvement in favor of capsaicin versus vehicle: 69.5 vs 53.4% with clinical improvement in pain status (P = 0.012), 26.1 vs. 14.6% with improvement in walking (P = 0.029), 18.3 vs. 9.2% with improvement in working (P = 0.019), 29.5 vs. 20.3% with improvement in sleeping (P = 0.036), and 22.8 vs. 12.1% with improvement in participating in recreational activities (P = 0.037).\n The results from this study suggest that topical 0.075% capsaicin is effective for reducing pain in patients with painful diabetic neuropathy with subsequent improvement in daily activities, enhancing the quality of the patient's life." ]

[ "To compare the safety of salmeterol xinafoate or placebo added to usual asthma care.\n A 28-week, randomized, double-blind, placebo-controlled, observational study.\n Study subjects were seen once in the study physician's office for screening and were provided all blinded study medication for the entire study period. Follow-up by telephone was scheduled every 4 weeks.\n Subjects (> 12 years old) with asthma as judged by the study physician were eligible. Individuals with a history of long-acting beta2-agonist use were excluded.\n Salmeterol, 42 mug bid via metered-dose inhaler (MDI), and placebo bid via MDI.\n Following an interim analysis in 26,355 subjects, the study was terminated due to findings in African Americans and difficulties in enrollment. The occurrence of the primary outcome, respiratory-related deaths, or life-threatening experiences was low and not significantly different for salmeterol vs placebo (50 vs 36; relative risk [RR] = 1.40; 95% confidence interval [CI], 0.91 to 2.14). There was a small, significant increase in respiratory-related deaths (24 vs 11; RR, 2.16; 95% CI, 1.06 to 4.41) and asthma-related deaths (13 vs 3; RR, 4.37; 95% CI, 1.25 to 15.34), and in combined asthma-related deaths or life-threatening experiences (37 vs 22; RR, 1.71; 95% CI, 1.01 to 2.89) in subjects receiving salmeterol vs placebo. The imbalance occurred largely in the African-American subpopulation: respiratory-related deaths or life-threatening experiences (20 vs 5; RR, 4.10; 95% CI, 1.54 to 10.90) and combined asthma-related deaths or life-threatening experiences (19 vs 4; RR, 4.92; 95% CI, 1.68 to 14.45) in subjects receiving salmeterol vs placebo.\n For the primary end point in the total population, there were no significant differences between treatments. There were small, but statistically significant increases in respiratory-related and asthma-related deaths and combined asthma-related deaths or life-threatening experiences in the total population receiving salmeterol. Subgroup analyses suggest the risk may be greater in African Americans compared with Caucasian subjects. Whether this risk is due to factors including but not limited to a physiologic treatment effect, genetic factors, or patient behaviors leading to poor outcomes remains unknown.", "To compare safety of salmeterol and salbutamol in treating asthma.\n Double blind, randomised clinical trial in parallel groups over 16 weeks.\n General practices throughout the United Kingdom.\n 25,180 patients with asthma considered to require regular treatment with bronchodilators who were recruited by their general practitioner (n = 3516).\n Salmeterol (Serevent) (50 micrograms twice daily) or salbutamol (200 micrograms four times a day) randomised in the ratio of two patients taking salmeterol to one taking salbutamol. All other drugs including prophylaxis against asthma were continued throughout the study.\n All serious events and reasons for withdrawals (medical and non-medical) whether or not they were considered to be related to the drugs.\n Fewer medical withdrawals due to asthma occurred in patients taking salmeterol than in those taking salbutamol (2.91% v 3.79%; chi 2 = 13.6, p = 0.0002). Mortality and admissions to hospital were as expected. There was a small but non-significant excess mortality in the group taking salmeterol and a significant excess of asthma events including deaths in patients with severe asthma on entry. Use of more than two canisters of bronchodilator a month was particularly associated with the occurrence of an adverse asthma event.\n Treatment over 16 weeks with either salmeterol or salbutamol was not associated with an incidence of deaths related to asthma in excess of that predicted. Overall control of asthma was better in patients allocated to salmeterol. Serious adverse events occurred in patients most at risk on entry and were probably due to the disease rather than treatment.", "This study investigates the long-term cardiovascular safety of salmeterol powder vs placebo in adolescent and adult patients with mild persistent asthma.\n Multicenter, randomized, double-blind, placebo-controlled, parallel-group study.\n Eighteen US clinical centers.\n Three hundred fifty-two patients (> or = 12 years) with mild persistent asthma (duration > or = 6 months) requiring pharmacotherapy; with FEV1 of 70 to 90% of predicted and without abnormal ECG/continuous ambulatory ECG (Holter).\n Randomized to twice-daily salmeterol powder (50 microg) or placebo via breath-actuated device for 52 weeks. Backup albuterol was available to control asthma symptoms.\n Cardiovascular safety was regularly assessed by 12-lead ECG with a 15-s lead II rhythm strip, 24-h continuous ambulatory ECG (Holter) monitoring, serial vital sign measurements, and review of adverse cardiovascular events. No deaths occurred during the study. No clinically significant between-group differences were observed in pulse rate, ECG QTc interval, median number of ventricular or supraventricular ectopic events, incidence of ventricular ectopic couplets and runs, or incidence of > 100 ventricular or supraventricular ectopic events in 24 h. No clinically significant between-group differences were observed in arterial BP or incidence of adverse cardiovascular events. Salmeterol was well tolerated throughout the 52-week study period, with a cardiovascular safety profile similar to that of placebo.\n Long-term, twice-daily pharmacotherapy with salmeterol powder is safe and is not associated with unfavorable clinically significant changes in cardiac function or increases in cardiovascular adverse effects.", "Traditional clinical outcomes have demonstrated that salmeterol improves pulmonary function and reduces asthma symptoms. However, they do not evaluate how patients perceive the effect of therapeutic intervention on day-to-day functioning and well-being.\n We sought to evaluate the impact of salmeterol on disease-specific quality of life with the Asthma Quality-of-Life Questionnaire, as well as the efficacy and safety of salmeterol in patients with stable asthma who were symptomatic despite daily use of inhaled corticosteroids.\n This was a randomized, double-blind, placebo-controlled, parallel-group study of 506 patients. Patients were treated with 42 microg salmeterol or placebo twice daily for 12 weeks delivered through a metered dose inhaler.\n Mean change from baseline in asthma quality-of-life scores was significantly greater (p < or = 0.006) after 12 weeks of treatment with salmeterol compared with placebo (\"as-needed\" albuterol) in global scores (1.08 vs 0.61) and individual domains (activity limitations, 0.91 vs 0.54; asthma symptoms, 1.28 vs 0.71; emotional function, 1.17 vs 0.65; and environmental exposure, 0.84 vs 0.47). Patients treated with salmeterol experienced significantly greater improvements from baseline to week 12 compared with placebo in FEV1 (0.42 L vs 0.15 L, p < 0.001), morning peak expiratory flow (47 L/min vs 14 L/min, p < 0.001), evening peak expiratory flow (29 L/min vs 11 L/min, p < 0.001), and asthma symptom scores (daytime scores reduced by 0.55 vs 0.30, p < 0.001). Patients treated with salmeterol used significantly less supplemental albuterol (reduced by 3 puffs/day vs 1 puff/day, p < 0.001).\n Salmeterol provided significantly greater improvement in quality-of-life outcomes in patients whose asthma symptoms are not well controlled with inhaled corticosteroids. These results demonstrate that the benefits of salmeterol are not limited to conventional clinical measures of efficacy.", "We compared the effects of salmeterol (Sm) (50 micrograms twice daily) with that of salbutamol (Sb) (200 micrograms four times daily) and placebo (P) in patients with mild-to-moderate asthma with asthma symptoms and related the effectiveness of these therapies between patients who used concurrent inhaled corticosteroids (ICS) and those who did not. The study was a 12-wk, multicenter, double-blind, placebo-controlled crossover trial with 367 adult asthmatics randomized to each trial medication for 4 wk. Inhaled Sb was provided as rescue medication to all patients throughout the trial. Only 80% of patients, albeit the majority, were receiving maintenance treatment with ICS throughout this trial; this reflects practice current in early 1990. Each study day, patients recorded their morning and evening peak expiratory flows (PEF), assessment of asthma symptoms, and use of rescue medication. Both morning and evening PEF were greater during treatment with Sm than with Sb (mean differences between the treatments of 29.8 and 14.3 L/min, respectively) or P (27.7 and 20.3 L/min, respectively) (p < 0.0001). Sm was also more effective than Sb or P in lowering diurnal variation in PEF and increasing the percentage of symptom-free days and rescue-free days and nights with no sleep disturbance (p < or = 0.0004). Sb was more effective than P in increasing evening PEF and the percentage of symptom-free days (p < 0.05) and rescue-free days (p < 0.0001). The same clinical superiority of Sm compared with Sb and P was observed in those patients using ICS (p < 0.001 for all treatment comparisons), and to a greater extent than in those patients not using ICS (i.e., Sm was more effective than Sb and P in just six of the 20 treatment comparisons; p < 0.05). In conclusion, Sm 50 micrograms twice daily is effective in the management of mild-to-moderate asthma and it further improves asthma control in patients already using ICS.", "Current treatment guidelines define inhaled corticosteroids such as fluticasone propionate (FP) as the cornerstone of anti-inflammatory therapy for asthma.\n The objective was to evaluate the efficacy and safety of adding salmeterol therapy to patients who remain symptomatic while receiving FP as compared with increasing the dose of FP.\n In a multicenter, double-blind study conducted over 24-weeks, 437 patients aged 12 years and older and receiving FP 88 microg twice daily for 2 to 4 weeks were randomly assigned to receive either salmeterol (42 microg twice daily) or FP 220 microg twice daily. The primary efficacy endpoint was morning peak expiratory flow. Secondary measures included FEV1, symptom scores, nighttime awakenings, and supplemental albuterol use. Safety was assessed by reported adverse events and asthma exacerbations.\n The addition of salmeterol resulted in significantly greater improvements in lung function and symptom control as compared with increasing the dose of FP. Over weeks 1 to 24, morning peak expiratory flow was increased by 47 L/min from baseline with salmeterol treatment as compared with 24 L/min with FP 220 microg twice daily (P < .001) while the percent of symptom-free days increased from baseline by 26% of days as compared with 10% of days (P < .001). The adverse event profiles were similar between groups and fewer exacerbations were reported with salmeterol treatment.\n The addition of salmeterol therapy to patients who remain symptomatic while using a low dose of FP was clinically and statistically superior to increasing the dose of FP.", "The aim of this study was to assess the efficacy and safety of inhaled salmeterol 100 micrograms b.d. (SM) versus inhaled salbutamol 400 micrograms q.d.s. (SB), both via the Diskhaler, when added to concurrent treatment, in asthmatic patients who were not controlled on high doses of inhaled steroids (> or = 1,500 micrograms beclomethasone dipropionate (BDP) or equivalent daily). This was a multicentre, parallel group, double-blind study in which 190 patients with a forced expiratory volume in one second (FEV1) or peak expiratory flow rate (PEFR) of 30-75% predicted and 15% reversibility to inhaled bronchodilator were randomized to treatment for 6 weeks. In the SM group, morning PEFR increased from 281 to 315 L-min-1 during treatment and in the SB group from 311 to 315 L.min-1 (p < 0.001). The SM group showed significantly better reduction in diurnal variation, from 39 to 22 L.min-1 during treatment, than the SB group (34 to 37 L.min-1) (p < 0.001). There was a significantly greater improvement in FEV1 in the SM group (from 1.63 to 1.85 L) than in the SB group (from 1.79 to 1.84 L). The SM group had significantly more symptom-free nights than the SB group (p < 0.001), and also more \"rescue-free\" nights (p = 0.04). The adverse event profile was similar in both groups. This study indicates that in asthmatic patients, not controlled on high-dose inhaled steroids, inhaled salmeterol 100 micrograms b.d. significantly improves lung function and reduces asthma symptoms.", "The efficacy and safety of the aerosol metered-dose inhaler (MDI) formulation of salmeterol for asthma symptoms have been established. Recently, salmeterol has been introduced as a micronized powder formulation administered via a breath-activated multidose powder inhaler (Diskus).\n A multicenter, randomized, double-blind, double-dummy, parallel-group, placebo-controlled study involving 498 adolescents and adults with mild-to-moderate asthma was conducted to compare the efficacy and safety of salmeterol powder 50 microg twice daily via Diskus, salmeterol aerosol 42 microg twice daily via MDI, and placebo.\n Patients were randomized to one of the three treatment groups for 12 weeks. Efficacy was assessed by serial measurements of forced expiratory volume in one second (FEV1) over 12 hours, daily peak expiratory flow (PEF), self-rated asthma symptom scores, nighttime awakenings, and supplemental albuterol use. Safety of each treatment was evaluated by monitoring vital signs, electrocardiograms, Holter monitoring, and occurrence of adverse events.\n As compared with placebo, both salmeterol powder and aerosol produced significant improvement in FEV1 and PEF and decreased nighttime awakenings and supplemental albuterol use. There were no significant differences in the efficacy of the two salmeterol formulations. The magnitude of improvement in pulmonary function was undiminished over the 12-week study. Both formulations of salmeterol were well tolerated, with safety profiles not significantly different from placebo.\n Results of this study indicate that salmeterol, administered either as a powder 50 microg twice daily via Diskus or as an aerosol 42 microg twice daily via MDI, produces clinically significant and comparable improvement in pulmonary function and is well tolerated in patients with mild-to-moderate persistent asthma.", "An inhaled glucocorticoid is currently the medication of choice for long-term control of persistent asthma in children. The role of long-acting beta2-adrenergic-receptor agonists, such as salmeterol, needs to be defined.\n We conducted a randomized, double-blind, placebo-controlled, parallel-group, one-year study of 241 children (mean [+/-SD] age, 9.3+/-2.4 years) with clinically stable asthma and less than one month of prior glucocorticoid use. We compared inhaled beclomethasone dipropionate (200 microg twice daily) with salmeterol xinafoate (50 microg twice daily) and placebo (lactose). The primary outcome measure, airway responsiveness (as assessed with a methacholine challenge) was evaluated before treatment; after 3, 6, 9, and 12 months of treatment (12 and 36 hours after study medications had been withheld); and 2 weeks after the end of treatment. Spirometry, symptoms, use of rescue medication (200 microg of albuterol inhaled as needed), and adverse effects were also assessed.\n During months 1 through 12 overall, beclomethasone was associated with significantly less airway hyperresponsiveness than salmeterol (P= 0.003) or placebo (P<0.001). This effect was lost two weeks after treatment had been stopped. As compared with placebo, beclomethasone was associated with less variability between morning and evening in the peak expiratory flow (P=0.002), as was salmeterol (P=0.02). Beclomethasone was also associated with a reduced need for albuterol as rescue therapy (P<0.001) and fewer withdrawals because of asthma exacerbations (P=0.03), but salmeterol was not (P=0.09 and 0.55, respectively). During months 1 through 12, linear growth was 3.96 cm in the children receiving beclomethasone, as compared with 5.40 cm in the salmeterol group (P=0.004) and 5.04 cm in the placebo group (P=0.018). Height was not measured after treatment ended.\n Beclomethasone was effective in reducing airway hyperresponsiveness and in controlling symptoms of asthma, but it was associated with decreased linear growth. Salmeterol was not as effective as beclomethasone in reducing airway hyperresponsiveness or in controlling symptoms; however, it was an effective bronchodilator and was not associated with rebound airway hyperresponsiveness, masking of symptoms, or adverse effects.", "The present study was set up to investigate whether salmeterol in children with asthma already treated with inhaled corticosteroids (ICS) leads to a sustained bronchodilator effect and decreased bronchial responsiveness, both during the day and night. Furthermore, we investigated whether cessation of salmeterol leads to a rebound increase in bronchial responsiveness. Forty children with asthma (aged 7-15 yrs) using ICS participated in a randomized, double-blind, parallel study. They received either twice daily 50 micrograms salmeterol or placebo. FEV1 and provocative concentration of methacholine that caused a 20% fall in FEV1 (PC20) were measured at 4:00 P.M. and 4:00 A.M. at baseline and after 16 wk. The same measurements were performed at 4:00 P.M. at 8 h after the first dose, and after 1 and 8 wk. After cessation of the study drug, FEV1 and PC20 were measured at 12 and 20 h and after 1 wk. Overall mean FEV1 from 1 to 16 wk of treatment was significantly higher in the salmeterol group than in the placebo group (difference, 4.9 +/- 2.0%, p = 0.01). Evolution in time of FEV1 did not differ significantly between the two groups (p = 0.09). Overall mean PC20 from 1 to 16 wk of treatment was not significantly higher with salmeterol than with placebo (difference, 0.7 +/- 0.4 doubling dose [DD] p = 0.07); evolution in time of PC20 did not differ significantly between the two groups (p = 0.58).(ABSTRACT TRUNCATED AT 250 WORDS)", "To evaluate the efficacy, safety, and impact on asthma-specific quality of life of salmeterol, a highly selective, long-acting beta 2-agonist, compared with that of placebo (i.e., \"as-needed\" albuterol).\n Randomized, double-blind, placebo-controlled, parallel-group, multicenter study.\n Five hundred thirty-eight nonsmoking symptomatic patients 12 years of age and older meeting American Thoracic Society asthma criteria were enrolled at 55 outpatient clinics; 443 patients completed the study. Patients were randomly assigned to treatment with either salmeterol aerosol 42 micrograms twice daily or placebo (as-needed albuterol) for 12 weeks. We assessed changes in quality of life using the Asthma Quality of Life Questionnaire (AQLQ). Efficacy measurements included daily peak expiratory flow (PEF) rate, daytime and nighttime asthma symptoms, results of pulmonary function tests, and supplemental albuterol use. Patients recorded their PEF rate, supplemental albuterol use, and asthma-related symptoms daily. Pulmonary function tests and AQLQ assessments were performed at baseline and after 4, 8, and 12 weeks of treatment. Safety measurements included vital signs, physical examination, and reports of clinical adverse events at baseline and after 4, 8, and 12 weeks of treatment.\n Mean changes from baseline in AQLQ global and domain scores were significantly greater in the salmeterol group compared with the placebo group (P < 0.001). Patients treated with salmeterol also had significant improvements in mean PEF rates, supplemental albuterol use, asthma symptom scores, and forced expiratory volume in 1 second compared with those given placebo. Both salmeterol and placebo were well tolerated and were not associated with any clinically significant changes in vital signs or physical examination findings.\n Salmeterol 42 micrograms twice daily resulted in significantly greater improvements in asthma-specific quality of life, pulmonary function, and asthma symptoms compared with placebo (as-needed albuterol) in patients with moderate persistent asthma.", "To compare the effects of addition of montelukast or salmeterol to inhaled corticosteroids (ICS) on the response to rescue beta2-agonist use after exercise-induced bronchoconstriction.\n A double-blind, placebo-controlled study was performed at 16 centers in the United States. Patients with asthma (n = 122, ages 15-58) whose symptoms were uncontrolled on Low-dose inhaled fluticasone and who had a history of exercise-induced worsening of asthma were randomized to receive either montelukast (10 mg once daily), salmeterol (50microg twice daily), or placebo for 4 weeks. Standardized spirometry after exercise challenge and beta2-agonist rescue was performed at baseline, week 1 and 4.\n Maximum achievable forced expiratory volume in 1 s (FEV1) percent predicted after rescue beta2-agonist improved in the montelukast (+1.5%) and placebo (+1.2%) groups at 4 weeks, but diminished in the salmeterol (-3.9%) group (P < 0.001). Although pre-exercise FEV1 was greatest with salmeterol (P = 0.10), patients taking montelukast had significantly greater protection from an exercise-induced decrease in FEV1 than those taking salmeterol (P < 0.001). Both the magnitude and rate of rescue bronchodilation were greater with montelukast compared with salmeterol (P < 0.001). Five minutes after rescue beta2-agonist, 92% of patients taking montelukast and 68% of those taking placebo had recovered to pre-exercise levels, whereas only 50% of those taking salmeterol had recovered to pre-exercise levels.\n In patients whose asthma symptoms remain uncontrolled using ICS, addition of montelukast permits a greater and more rapid rescue bronchodilation with a short-acting beta2-agonist than addition of salmeterol and provides consistent and clinically meaningful protection against exercise-induced bronchoconstriction.", "Current guidelines on asthma management recommend the early use of inhaled corticosteroids. Recent studies of patients with moderate to severe asthma show that the addition of salmeterol is superior to a further increase of the steroids. In this study with adult, mild persistent asthma patients, we compared the effects of adding salmeterol 50 microg b.i.d. versus beclomethasone dipropionate (BDP) 200 microg b.i.d. (both via Diskhaler dry powder inhaler) to the low-dose inhaled steroids. A double-blind, randomized, parallel-group study was conducted with a run-in period of 2 weeks and a treatment period of 12 weeks. Patients (n = 233) were randomized with a peak expiratory flow (PEF) reversibility of 22 +/- 10% (mean +/- SD) in the run-in period. The morning PEF was 84 +/- 17% predicted and the age was 42 +/- 14 years (45% males). The average prestudy inhaled steroid dose was 361 microg daily. Within a week of salmeterol treatment the daily PEF recordings reached maximal levels. At the end of the treatment period the evening PEF remained significantly better in the salmeterol group than in the BDP group (p = 0.036). The PEFs, measured at the general practitioners' (GPs') office, were at least 95% of the predicted values and the post-salbutamol values at the end of both treatments. However, the salmeterol group had already obtained this level after 2 weeks and differed significantly from the beclomethasone group (p = 0.003 for percent predicted and p = 0.0007 for post-salbutamol PEF values). The symptom scores and the use of rescue medication showed a similar profile. Quality of life improved with both treatments, but without significant statistical differences between the groups. The frequency of adverse events, typical for beta2-agonists, was low and showed no differences between the groups. These results showed that the addition of salmeterol is at least as effective as adding beclomethasone in normalizing peak flows and improving asthma control in mild persistent asthma patients. Furthermore, salmeterol has a much faster onset of action.", "The aim of the study was to compare the efficacy of the inhaled long-acting beta2-agonists eformoterol and salmeterol when added to existing inhaled corticosteroid (ICS) therapy in symptomatic asthmatic children. This randomized, 12-week, parallel-group study, performed in a primary care setting, included 156 children and adolescents (aged 6-17 years) with moderate persistent asthma. Patients were randomized to open-label eformoterol (Oxis) Turbohaler 9 microg (delivered dose) or salmeterol Accuhaler 50 microg, both b.i.d, added to current ICS. Assessments included: changes in daytime reliever beta2-agonist therapy (primary variable), total 24-h reliever use, lung function, clinic and diary symptom scores, patient and carer health-related quality of life (HRQL) and adverse events. Daytime reliever use decreased significantly (p < 0.001) from baseline by 65% and 52%, respectively in the eformoterol and salmeterol treatment groups. Compared with salmeterol, eformoterol produced a greater decrease in daytime (-0.46 inhalations/day; p = 0.081) and 24-h (-0.70 inhalations/day; p = 0.043) reliever use. The percentage of patients who did not require any reliever medication during the study was significantly higher in the eformoterol group (p < 0.05 vs. salmeterol at weeks 8 and 12). Clinic and diary card peak expiratory flow and symptom measures all improved from baseline in both treatment arms. There was a significantly greater effect in favour of eformoterol for the reduction in clinic-assessed overall night-time symptoms (p < 0.05 vs. salmeterol). Clinically relevant improvements in patient-assessed HRQL occurred during treatment with eformoterol and salmeterol, but carer-assessed HRQL was improved to a clinically relevant extent, only with eformoterol. Both treatments were well tolerated. In children and adolescents with moderate persistent asthma, add-on therapy with eformoterol was well tolerated and at least as effective as salmeterol.", "The addition of long-acting beta(2) agonists to inhaled corticosteroid (ICS) therapy in symptomatic patients with asthma improves clinical status more than increasing the dose of ICS. It has been suggested that these benefits could be at the cost of an increase in airway inflammation, but few histopathological studies have been performed in the relevant group. In a double-blind, parallel-group, placebo-controlled study, we randomly assigned 50 symptomatic patients with asthma who were receiving ICS (range, 100 -500 microgram/d) to 12 wk of supplementary treatment with salmeterol (50 microgram twice daily) or fluticasone (100 microgram twice daily) or placebo. Bronchial biopsies and BAL were obtained from 45 patients before and after treatment and analyzed. After treatment with salmeterol there was no deterioration of airway inflammation as assessed by mast cells, lymphocytes, or macrophages in BAL or biopsies, but rather a significant fall in EG1-positive eosinophils in the lamina propria (from a median 18.3 to 7.6 cells/mm, p = 0.01), which was not seen after treatment with fluticasone. The only cellular effect of added fluticasone was a decrease in BAL lymphocyte activation. There was a concurrent improvement in clinical status, more marked with salmeterol than with increased ICS. Thus, adding salmeterol to ICS is not associated with increased \"allergic\" airway inflammation, but conversely with a complementary antieosinophil effect.", "Twenty-four children aged 12-17 years entered a randomized, double-blind placebo-controlled study investigating the use of salmeterol in chronic severe asthma. In addition to their usual medication, the children were given either placebo or 100 micrograms salmeterol b.d. by dry powder inhalation. Treatment was continued throughout one term at a residential school for asthma. Symptom scores, peak expiratory flow rates, spirometry and quality-of-life scores were compared between the two treatment groups. One child withdrew during the run-in period. Twelve pupils received placebo and 11 pupils received salmeterol. There were consistent improvements in favour of salmeterol, reaching statistical significance for morning and evening peak flow rates and spirometry when measured on four occasions during the study period. There were no medication-related adverse events recorded and no pulse rate changes. Salmeterol (100 micrograms b.d.) is well tolerated and efficacious in older children with chronic severe asthma.", "Beta2-adrenergic agonists are frequently used for the prevention and relief of bronchospasm in patients with reversible obstructive airway disease. Formoterol and salmeterol are long-acting beta2-agonists. In addition to its long duration of action, formoterol has been reported to have an onset of action similar to that of albuterol.\n This study compared the effects on lung function of regular twice-daily inhalation of formoterol or salmeterol in adults with moderate to moderately severe persistent asthma who were receiving daily inhaled corticosteroids.\n In this 6-month, multicenter, open-label, parallel-group study, patients with moderate or moderately severe asthma were randomized to receive either formoterol 12 microg BID or salmeterol 50 microg BID. The primary end point was mean morning peak expiratory flow (PEF) measured 5 minutes after dosing and entered in a patient diary each day during the first 4 weeks of treatment. Secondary end points included mean morning and evening predose PEF and number of episode-free days recorded in the patient diaries during the first 4 weeks of treatment, use and time of rescue medication, symptom scores, and overall mean morning predose PEF (spirometric measurements made by the physician during scheduled visits) for the entire treatment period. Safety assessments included spontaneously reported adverse events and vital signs.\n A total of 528 patients were randomized to study treatment, 262 to formoterol and 266 to salmeterol. There were no significant differences in demographic or baseline characteristics between treatment groups, except in the proportion of current smokers in the formoterol group (4.6%) compared with the salmeterol group (1.5%; P = 0.039). Based on the information recorded in patients' diaries, those receiving formoterol showed significant improvement in mean morning PEF measured 5 minutes after dosing (P < 0.001), reduced use of rescue medication (P < 0.03), and an increased number of episode-free days (P < 0.04) compared with patients receiving salmeterol. Mean predose morning and evening PEF and symptom scores based on diary data and mean morning predose PEF based on measurements obtained during office visits were comparable between the 2 treatment groups throughout the study.\n In this open-label trial, patients randomized to formoterol treatment had greater improvement in mean PEF 5 minutes after dosing, required significantly less rescue medication (fewer actuations of albuterol), and experienced more episode-free days compared with patients receiving salmeterol. Thus, although both formoterol and salmeterol are long-acting beta2-agonists, formoterol had a more rapid onset of action." ]

[ "Topical corticosteroids are frequently used drugs, but little is known of the exposure during pregnancy and birth outcome.\n In a population-based follow-up study restricted to primigravida women, we examined the risk of low birth weight, malformations and other birth outcomes following pregnancy upon exposure to topical corticosteroids. We compared the offspring of 363 women exposed to topical corticosteroids during pregnancy with 9263 controls, who received no prescriptions at all.\n The prevalence of malformations was 2.9% among 170 infants exposed during the first trimester and 3.6% among the controls. Adjusted odds ratios for low birth weight, malformations and preterm delivery among women receiving weak/medium strong corticosteroids were 0.7 (95% CI 0.17-2.85), 0.93 (95% CI 0.23-3.80) and 1.04 (95% CI 0.56-1.92), respectively, and adjusted odds ratios for strong/very strong corticosteroids were 1.23 (95% CI 0.45-3.37), 0.56 (95% CI 0.14-2.28) and 0.99 (95% CI 0.54-1.84), respectively.\n The study showed no increased risk of low birth weight, malformations or preterm delivery in the offspring of women exposed to topical corticosteroid during pregnancy.", "The teratogenic potential of oral and topical corticosteroid treatment during pregnancy was evaluated in the population-based large dataset of the Hungarian Case-Control Surveillance of Congenital Abnormalities, 1980-1994. Corticosteroid tablet pregnancy exposure was 1.55% among 20,830 malformed cases and 1.41% among 35,727 healthy control births (P = 0.2). Corticosteroid ointment pregnancy exposure was 0.35% among malformed and 0.33% among control births (P = 0.7). The absolute risk of oral and ointment corticosteroid treatment was low in pregnancy and particularly in the second and third months of gestation, i.e., in the critical period for major congenital abnormalities. The adjusted odds ratio and the analysis of case-control pairs did not show any association between the rate of different congenital abnormalities and the corticosteroid treatment in the second and third months of gestation. Thus, treatments with corticosteroids in pregnancy do not appear to noticeably increase the risk of congenital abnormalities in humans.", "There are no randomized data on the effect of repeat courses of corticosteroids during pregnancy on newborn pulmonary function. Our objective was to compare the effect of a single remote course of antenatal steroids (AS) with weekly courses of AS on functional residual capacity (FRC) and respiratory compliance in preterm infants.\n Pregnant women 25 to 33 weeks' gestation, who remained undelivered 1 week after their first course of antenatal corticosteroids (two 12-mg doses of betamethasone) were randomized to weekly courses of corticosteroids versus weekly placebo until delivery or 34 weeks' gestation. FRC was measured with the nitrogen washout technique and respiratory compliance with the single breath occlusion technique within 48 hours of life.\n Thirty-seven infants (mean gestational age at delivery approximately 32.5 weeks) were studied. Maternal and infant demographics were similar. There was no significant difference in FRC (28.5 vs 27.5 mL/kg) or respiratory compliance between the infants who received a single remote course of antenatal corticosteroids and those who received weekly courses of corticosteroids until delivery. There was no significant difference in admission head circumference or birth weights between the groups.\n Our results demonstrate that weekly repetitive courses of AS do not significantly increase FRC or respiratory compliance in preterm infants when compared with a single remote course of steroids given at a mean gestational age of 29 weeks.", "The possible association between oral cleft in the newborn and maternal exposure to corticoids during pregnancy is still controversial. The aim of this study was to test this association by a case-control analysis using the large multicentric MADRE database.\n The MADRE database is a collection of information on malformed infants with a history of maternal first-trimester drug exposure. Nine malformation registries participate in the data collection. Cases were defined as infants presenting with a cleft palate or cleft lip, and exposure was defined by the use of corticosteroids during the first trimester of pregnancy.\n After 12 years of data collection, the database includes data on 11,150 malformed infants. A slight association is observed between exposure to corticoids for systemic use and the occurrence of cleft lip with or without cleft palate (OR, 2.59; 95% CI, 1.18-5.67).\n If the observed association is real, an interpretation is suggested, based on a likely interaction between corticosteroids and environmental dioxins. It is indeed possible that human fetuses may become sensitive to the teratogenic effect of corticosteroids when they are exposed in utero to environmental pesticides as well.\n Copyright 2003 Wiley-Liss, Inc.", "The purpose of this study was to examine whether maternal corticosteroid use during pregnancy is associated with delivering an infant with an orofacial cleft.\n This study included data on deliveries from the National Birth Defects Prevention Study, which is a population-based case-control study. Exposures were assessed by telephone interviews for mothers of 1141 cases with cleft lip +/- cleft palate (CLP), 628 with cleft palate (CP), and 4143 controls.\n Mothers of 33 infants with CLP (2.9%), mothers of 6 infants with CP (1.0%), and 72 control subjects (1.7%) reported corticosteroid use from 4 weeks before through 12 weeks after conception. The crude odds ratio for \"any\" vs \"no\" use was 1.7 (95% CI, 1.1-2.6) for CLP and 0.5 (0.2-1.3) for CP. When analyzed by route of administration and medication components, odds ratios for CLP tended to be elevated, and odds ratios for CP tended to be close to 1.\n Our results suggest a moderately increased risk of CLP among women who use corticosteroids during early pregnancy.", "This study was carried out to examine the effect of antenatal corticosteroid therapy on pregnancies complicated by premature rupture of membranes (PROMs). For this purpose, 139 patients with a singleton pregnancy (27-34 weeks of gestation) complicated by PROMs were evaluated prospectively during the period January 1997 to February 1999 at two Jordanian military hospitals (Prince Rhashed and Prince Zaid). Patients were allocated into two groups; Group 1 included 72 patients treated with dexamethsone (24 mg divided into 4 doses 12 hours apart), and Group 2 which included 67 patients whoreceived no treatment (control group). All women were examined clinically and the diagnosis of PROMs was demonstrated using vaginal speculum, nitrazine paper examination and ultrasonography. All neonates were evaluated clinically, radiologically, and by laboratory investigations. Pearson's Chi-square and Fisher's exact tests were used to assess the significance of differences between the two study groups. Respiratory distress syndrome (RDS), necrotizing enterocolitis (NEC), intraventricular haemorrhage (IVH), and days of hospital stay were significantly reduced in premature infants of the corticosteroid treated women compared with the controls (p<0.04, p<0.04, p<0.04, and p<0.05, respectively). The perinatal mortality was significantly decreased among the corticosteroid treated group in the gestational subgroups 31-32 and 33-34 weeks (p<0.04), and in all birth weight subgroups (p<0.03). RDS was statistically a significant factor which resulted in increased perinatal mortality in the control group (p=0.02). Regarding the occurrence of postpartum endometritis there was a statistically significant increase among the corticosteroid treated group compared with the controls (p<0.04). Conclusion: Antenatal corticosteroid therapy in pregnancies complicated by PROMs has a positive influencing effect on premature infants between 31 and 34 weeks of gestation, decreasing significantly the perinatal morbidity and mortality. It should be used with particular relevance to the developing world where surfactant is not available or where neonatal intensive care units are lacking." ]

[ "This study was designed to determine the effect of garlic tablet (Garlet) on plasma lipids, and platelet aggregation and the efficacy of this treatment in the prevention of preeclampsia.\n In a randomized, single-blind, placebo-controlled study, 100 primigravidas with positive roll-over test were treated with daily doses of 800mg Garlet/day (n=50) or 800mg/day placebo (n=50) during the third trimester of pregnancy. Serum total cholesterol, LDL-and HDL-cholesterol, triglyceride, and platelet aggregation were measured before and after the treatment. Blood pressure, weight, and edema were also examined during the entire study period.\n In the case group, there was no significant difference in the means of total cholesterol, HDL, LDL, and triglyceride before and after the experiment. Furthermore, the inhibition of platelet aggregation did not show any significant difference before and after the treatment. There were not any significant difference in the means of HDL, LDL, triglyceride, inhibition of platelet aggregation, the means of systolic and diastolic blood pressure and the mean arterial blood pressure (MAP), between the two groups, but there was a significant difference in the means of total cholesterol (P=0.038) and hypertension alone (P=0.043).\n The administration of 800mg/day of Garlet during the third trimester of pregnancy was effective in reducing the occurrence of hypertension alone, but it was no effective in preventing of preeclampsia." ]

[ "Venous thromboembolic events (VTE) are serious complications in children and for which the standard of care, unfractionated heparin followed by oral anticoagulation (UFH/OA), is problematic. The objective of REVIVE was to compare the efficacy and safety of a low molecular weight heparin (reviparin-sodium) to UFH/OA for the treatment of VTE in children.\n This multicenter, open-label study, with blinded central outcome adjudication, randomized patients with objectively confirmed VTE to receive either reviparin-sodium or UFH/OA. Dose adjustments were made using nomograms. The efficacy outcome was based on recurrent VTE and death due to VTE during the 3-month treatment period. The safety outcomes were major bleeding, minor bleeding and death. Due to slow patient accrual, REVIVE was closed prematurely.\n At 3 months, with reviparin-sodium, 2/36 patients (5.6%) had recurrent VTE or death compared to 4/40 patients (10.0%) receiving UFH/OA (odds ratio=0.53; 95% CI=(0.05, 4.00); Fisher's exact test: 2P=0.677). There were 7 major bleeds, 2/36 (5.6%) in the reviparin-sodium group and 5/40 (12.5%) in UFH/OA group (odds ratio=0.41; 95% confidence interval 0.04, 2.76); Fisher's exact test: P=0.435). There were 5 deaths during the study period, 1 (2.8%) in the reviparin-sodium group and 4 (10.0%) in the UFH/OA group. All five deaths were unrelated to VTE but one was due to an intracranial hemorrhage in the UFH/OA group.\n Although limited by small sample size, REVIVE provides valuable information on the incidence of recurrent VTE, major bleeding and problematic issues associated with therapy of VTE in children.", "Low-molecular-weight heparins are frequently used to treat venous thromboembolism, but optimal dosing regimens and clinical outcomes need further definition.\n In this multicenter, open-label study with blinded adjudication of end points, we randomly assigned patients with acute deep-vein thrombosis to one of three treatment regimens: intravenous administration of unfractionated heparin; subcutaneous administration of a low-molecular-weight heparin, reviparin, twice a day for one week; or subcutaneous administration of reviparin once a day for four weeks. The primary end point was evidence of regression of the thrombus on venography on day 21; secondary end points were recurrent venous thromboembolism, major bleeding within 90 days after enrollment, and death.\n Of the patients receiving unfractionated heparin, 40.2 percent (129 of 321) had thrombus regression, as compared with 53.4 percent (175 of 328) of patients receiving reviparin twice daily and 53.5 percent (167 of 312) of the patients receiving reviparin once daily. With regard to thrombus regression, reviparin administered twice daily was significantly more effective than unfractionated heparin (relative likelihood of thrombus regression, 1.28; 97.5 percent confidence interval, 1.08 to 1.52), as was reviparin administered once daily (relative likelihood, 1.29; 97.5 percent confidence interval, 1.08 to 1.53). Mortality and the frequency of episodes of major bleeding were similar in the three groups.\n In acute deep-vein thrombosis, reviparin regimens are more effective than unfractionated heparin in reducing the size of the thrombus. Reviparin is also more effective than unfractionated heparin for the prevention of recurrent thromboembolism and equally safe.", "The use of thrombolytic agents in the treatment of hemodynamically stable patients with acute submassive pulmonary embolism remains controversial.\n We conducted a study of patients with acute pulmonary embolism and pulmonary hypertension or right ventricular dysfunction but without arterial hypotension or shock. The patients were randomly assigned in double-blind fashion to receive heparin plus 100 mg of alteplase or heparin plus placebo over a period of two hours. The primary end point was in-hospital death or clinical deterioration requiring an escalation of treatment, which was defined as catecholamine infusion, secondary thrombolysis, endotracheal intubation, cardiopulmonary resuscitation, or emergency surgical embolectomy or thrombus fragmentation by catheter.\n Of 256 patients enrolled, 118 were randomly assigned to receive heparin plus alteplase and 138 to receive heparin plus placebo. The incidence of the primary end point was significantly higher in the heparin-plus-placebo group than in the heparin-plus-alteplase group (P=0.006), and the probability of 30-day event-free survival (according to Kaplan-Meier analysis) was higher in the heparin-plus-alteplase group (P=0.005). This difference was due to the higher incidence of treatment escalation in the heparin-plus-placebo group (24.6 percent vs. 10.2 percent, P=0.004), since mortality was low in both groups (3.4 percent in the heparin-plus-alteplase group and 2.2 percent in the heparin-plus-placebo group, P=0.71). Treatment with heparin plus placebo was associated with almost three times the risk of death or treatment escalation that was associated with heparin plus alteplase (P=0.006). No fatal bleeding or cerebral bleeding occurred in patients receiving heparin plus alteplase.\n When given in conjunction with heparin, alteplase can improve the clinical course of stable patients who have acute submassive pulmonary embolism and can prevent clinical deterioration requiring the escalation of treatment during the hospital stay.\n Copyright 2002 Massachusetts Medical Society", "To compare the effectiveness and safety of low-dose unfractionated heparin and a low-molecular-weight heparin as prophylaxis against venous thromboembolism after colorectal surgery.\n In a multicenter, double-blind trial, patients undergoing resection of part or all of the colon or rectum were randomized to receive, by subcutaneous injection, either calcium heparin 5,000 units every 8 hours or enoxaparin 40 mg once daily (plus two additional saline injections). Deep vein thrombosis was assessed by routine bilateral contrast venography performed between postoperative day 5 and 9, or earlier if clinically suspected.\n Nine hundred thirty-six randomized patients completed the protocol and had an adequate outcome assessment. The venous thromboembolism rates were the same in both groups. There were no deaths from pulmonary embolism or bleeding complications. Although the proportion of all bleeding events in the enoxaparin group was significantly greater than in the low-dose heparin group, the rates of major bleeding and reoperation for bleeding were not significantly different.\n Both heparin 5,000 units subcutaneously every 8 hours and enoxaparin 40 mg subcutaneously once daily provide highly effective and safe prophylaxis for patients undergoing colorectal surgery. However, given the current differences in cost, prophylaxis with low-dose heparin remains the preferred method at present.", "The effect of LMW heparin (Kabi 2165, Fragmin) was compared with placebo for the prevention of DVT in 103 patients with acute ischemic stroke using a prospective, double-blind, randomized trial design. Treatment was started within 72 hours, and LMW heparin was administered subcutaneously once daily according to body weight classes, which corresponded to about 55 to 65 Factor-Xa inhibitory U/kg, for 14 days, or until discharge from the hospital, if earlier. All patients underwent thrombosis surveillance with unilateral venography of the paretic limb. Evaluation of venography could be performed in 42 of 52 patients randomized to LMW heparin and in 50 of 51 patients randomized to placebo. The frequency of DVT was 15 of 42 patients or 36% (95% confidence interval 22 to 52%) in the LMW heparin group and 17 of 50 patients or 34% (21 to 49%) in the placebo group. The frequency of proximal thrombi was 5 of 42 (12%) and 8 of 50 (16%), respectively. There was one fatal pulmonary embolism in the placebo group. The mortality rate (28 days follow-up) was 5 of 52 in the LMW heparin group and 1 of 51 in the placebo group (p = 0.24). None of the deaths was related to treatment. No major hemorrhagic complications were observed. The mean Factor Xa inhibitory activity levels at peak concentration were 0.34 U/ml on day 2 and 0.42 U/ml on day 12 (p = 0.02). We conclude that LMW heparin in the dose range studied did not provide efficient prophylaxis against DVT in patients with acute ischemic stroke.", "The treatment of unstable angina targets the specific pathophysiological thrombotic process at the site of the active culprit lesion. In unstable angina due to a restenotic lesion, smooth muscle cell proliferation and increased vasoreactivity may play a more important role than thrombus formation. Therefore, the relative benefits of nitroglycerin and heparin might differ in unstable angina associated with restenosis compared with classic unstable angina.\n We randomized 200 patients hospitalized for unstable angina within 6 months after angioplasty (excluding those with intracoronary stents) to double-blind administration of intravenous nitroglycerin, heparin, their combination, or placebo for 63+/-30 hours. Recurrent angina occurred in 75% of patients in the placebo and heparin-alone groups, compared with 42.6% of patients in the nitroglycerin-alone group and 41.7% of patients in the nitroglycerin-plus-heparin group (P<0.003). Refractory angina requiring angiography occurred in 22.9%, 29.2%, 4. 3%, and 4.2% of patients, respectively (P<0.002). The odds ratios for being event free were 0.24 (95% CI, -0.13 to 0.45, P=0.0001) for nitroglycerin versus no nitroglycerin and 0.98 (95% CI, -0.55 to 1. 73, P=NS) for heparin versus no heparin. No patient died or suffered myocardial infarction.\n Intravenous nitroglycerin is highly effective in preventing adverse ischemic events (recurrent or refractory angina) in patients with unstable angina secondary to restenosis, whereas heparin has no effect." ]

[ "The study objective is to evaluate the effect of monetary incentives on response rates of adolescents to a smoking-related survey as the first step toward participation in an intervention trial.\n A sample of 4,200 adolescent members of a managed care organization were randomized to one of four incentive groups: a $2 cash group, a $15 cash group, a $200 prize drawing group, or a no-incentive group. We compared group-specific response rates and willingness to be contacted about future study activities, as well as costs.\n Incentives increased survey response rates (55% response without incentive vs. a 69% response with incentive), with response of 74% in the $15 cash group, 69% in the token group, and 63% with a prize incentive. Incentives did not adversely affect willingness of adolescents to be contacted about a smoking intervention, (65% willing with incentives vs. 60% without, P = 0.03). In terms of cost per additional survey completed, token and prize groups were marginally more expensive than the no-incentive group ($0.40 and $1.42, respectively) while the large cash incentive was substantially more costly ($11.37).\n Monetary incentives improve response rates to a mailed survey, without adverse impact on willingness to further participate in intervention activities. However, a variety of issues must be considered when using incentives for recruitment to intervention studies.\n Copyright 2000 American Health Foundation and Academic Press.", "To evaluate the impact of a classroom-based, Web-assisted tobacco intervention addressing smoking prevention and cessation with adolescents.\n A two-group randomized control trial with 1,402 male and female students in grades 9 through 11 from 14 secondary schools in Toronto, Canada. Participants were randomly assigned to a tailored Web-assisted tobacco intervention or an interactive control condition task conducted during a single classroom session with e-mail follow-up. The cornerstone of the intervention was a five-stage interactive Web site called the Smoking Zine (http://www.smokingzine.org) integrated into a program that included a paper-based journal, a small group form of motivational interviewing, and tailored e-mails.\n Resistance to smoking, behavioral intentions to smoke, and cigarette use were assessed at baseline, postintervention, and three- and six-month follow-up. Multilevel logistic growth modeling was used to assess the effect of the intervention on change over time.\n The integrated Smoking Zine program helped smokers significantly reduce the likelihood of having high intentions to smoke and increased their likelihood of high resistance to continued cigarette use at 6 months. The intervention also significantly reduced the likelihood of heavy cigarette use adoption by nonsmokers during the study period.\n The Smoking Zine intervention provided cessation motivation for smokers most resistant to quitting at baseline and prevented nonsmoking adolescents from becoming heavy smokers at 6 months. By providing an accessible and attractive method of engaging young people in smoking prevention and cessation, this interactive and integrated program provides a novel vehicle for school- and population-level health promotion.", "Experimental evaluation of comprehensive community wide programme to prevent adolescent tobacco use.\n Eight pairs of small Oregon communities (population 1700 to 13 500) were randomly assigned to receive a school based prevention programme or the school based programme plus a community programme.

An effect on the slope of prevalence across time points was evident only when time 2 data points were eliminated from the analysis. The intervention affected the prevalence of smokeless tobacco among grade 9 boys at time 2. There were also significant effects on the slope of alcohol use among ninth graders and the quadratic slope of marijuana for all students.\n The results suggest that comprehensive community wide interventions can improve on the preventive effect of school based tobacco prevention programmes and that effective tobacco prevention may prevent other substance use.", "This paper examines the effectiveness of the \"Smoke-Free Class Competition\" in delaying the onset of smoking in adolescence. Each participating class must decide if they want to be a \"smoke-free class\" for the 6-month period from fall to spring. Classes monitor their (non-)smoking behavior and report it to the teacher regularly. Classes in which pupils refrain from smoking for this period of time participate in a prize draw, in which they can win a number of attractive prizes.\n To evaluate the effectiveness of the competition, a sample of 131 participating and nonparticipating classes (number of pupils 2,142; mean age 12.9 years, SD = 0.98) was compared with regard to their smoking behavior. Smoking status was determined by self-assessment on three occasions: (a) prior to the beginning of the competition, (b) 1 month after the competition, and (c) 1 year after the start of the competition.\n From pretest to posttest smoking increased by 7.5% in the comparison group, while it decreased by 0.2% in the intervention group (OR = 2.19; P < 0.001). In the follow-up measurement, a clear increase in smoking prevalence occurs in all groups; however, the pupils in the intervention condition still have a significant lower increase of smoking (OR = 1.45; P < 0.01). Moreover, with regard to the nonsmokers at baseline, pupils in the comparison group showed significantly higher prevalences in smoking than the intervention group in the postmeasurement, 7.8 versus 13.9% (OR = 1.98; P < 0.001), as well as in the in the follow-up-measurement, 17 versus 21.3% (OR = 1.36; P < 0.05).\n The results suggest that the participation in the competition could delay the onset of smoking in adolescence.", "Schools in many countries undertake programmes for smoking prevention, but systematic reviews have shown mixed evidence of their effectiveness. Most peer-led approaches have been classroom-based, and rigorous assessments are scarce. We assessed the effectiveness of a peer-led intervention that aimed to prevent smoking uptake in secondary schools.\n We undertook a cluster randomised controlled trial of 10 730 students aged 12-13 years in 59 schools in England and Wales. 29 schools (5372 students) were randomly assigned by stratified block randomisation to the control group to continue their usual smoking education and 30 (5358 students) to the intervention group. The intervention (ASSIST [A Stop Smoking In Schools Trial] programme) consisted of training influential students to act as peer supporters during informal interactions outside the classroom to encourage their peers not to smoke. Follow-up was immediately after the intervention and at 1 and 2 years. Primary outcomes were smoking in the past week in both the school year group and in a group at high risk of regular smoking uptake, which was identified at baseline as occasional, experimental, or ex-smokers. Analysis was by intention to treat. This study is registered, number ISRCTN55572965.\n The odds ratio of being a smoker in intervention compared with control schools was 0.75 (95% CI 0.55-1.01) immediately after the intervention (n=9349 students), 0.77 (0.59-0.99) at 1-year follow-up (n=9147), and 0.85 (0.72-1.01) at 2-year follow-up (n=8756). The corresponding odds ratios for the high-risk group were 0.79 (0.55-1.13 [n=3561]), 0.75 (0.56-0.99 [n=3483]), and 0.85 (0.70-1.02 [n=3294]), respectively. In a three-tier multilevel model with data from all three follow-ups, the odds of being a smoker in intervention compared with control schools was 0.78 (0.64-0.96).\n The results suggest that, if implemented on a population basis, the ASSIST intervention could lead to a reduction in adolescent smoking prevalence of public-health importance." ]

[ "Laparoscopic cholecystectomy has rapidly become established as the treatment of choice for cholecystolithiasis. There is very little evidence, however, to support the claimed benefit to patients. In the present study 30 consecutive patients below the age of 65 years without acute cholecystitis and with no signs of common bile duct stones were randomized to laparoscopic or conventional open cholecystectomy. Median (interquartile range) intravenous consumption of pethidine with a patient-controlled injection device between 13 and 24 h after surgery was 125 (62-175) mg in patients who underwent the laparoscopic procedure and 200 (150-250) mg in those who had open operation. Urinary adrenaline and cortisol levels as well as those of plasma glucose, C-reactive protein and interleukin 6 were increased after surgery in both groups of patients, but without any significant difference between them. The mean(s.d.) duration of postoperative hospital stay (2.8(0.8) versus 1.8(0.6) days) and sick leave (24.0(4.4) versus 11.7(4.1) days) was significantly longer with open than laparoscopic cholecystectomy. The findings demonstrate obvious advantages of laparoscopic surgery as regards postoperative pain and convalescence, although factors reflecting the magnitude of trauma did not differ.", "Laparoscopic cholecystectomy (LC) has displaced open cholecystectomy (OC) in the management of cholelithiasis. However, there are few studies on the role of this technique in patients who run a high risk of surgical complications. We performed a prospective study in 264 patients aged >65 years undergoing surgery for symptomatic cholelithiasis. They were divided into two groups according to the surgical technique performed: OC (131 patients) and LC (133 patients). Conversion from LC to OC was necessary in 11 patients (8.3%). Mean surgery time was 70.9 min for the OC group and 75 min for the LC group. The LC group had a lower rate of postoperative complications (13.53%) than the OC group (23.6%). The incidence of mild complications was similar in both groups; however, the rate of moderate complications was significantly higher in the OC group. Hospital stay was significantly longer in the OC group (9.9 days) than in the LC group (3.71 days). These results suggest that LC should be indicated in elderly patients, as they are better than those obtained with with OC and involve a lower morbidity rate and shorter hospital stay.", "To compare laparoscopic with open cholecystectomy.\n Prospective random control trial.\n Central Hospital of Akershus, Nordbyhagen, Norway.\n 74 consecutive patients due to undergo elective cholecystecomy between October 1990 and June 1991.\n Two patients were excluded from randomisation, and two were withdrawn after randomisation. The remaining 70 were randomly allocated to open or laparoscopic cholecystectomy (n = 35 in each group).\n Duration of operation and postoperative stay in hospital, amount of postoperative pain, incidence of complications, and duration of convalescence and sick leave.\n Laparoscopic cholecystectomy took twice as long as open (median [range] 100 [52-180] minutes compared with 50 [15-115], p < 0.01), but patients stayed in hospital half the time (2 [1-9] days compared with 4 [2-22], p < 0.01); required less opiate analgesia (4 [0-20] doses compared with 6 [0-13], p = 0.02; took less sick leave (11 [4-267] days (n = 18) compared with 34 [20-48] (n = 22), p < 0.01); and spent less time in convalescence (8 [3-40] days (n = 17) compared with 49 [10-247] (n = 12), p < 0.01). There were six complications in the laparoscopy group and seven in the open cholecystectomy group.\n Because of the significant differences between laparoscopic and open cholecystectomy we have now adopted the laparoscopic method as our standard, but we think that we can improve our results further by refining our operative techniques and giving our patients more information.", "Three hundred and ten patients having elective cholecystectomy were randomized to either laparoscopic cholecystectomy or mini-cholecystectomy. There were 155 patients in each group. Conversion to open cholecystectomy was significantly more common with laparoscopic cholecystectomy (13 versus 4 per cent) and complications were significantly more frequent with laparoscopic cholecystectomy (9 versus 3 per cent). If laparoscopic cholecystectomy was successful, hospital stay was significantly shorter than for mini-cholecystectomy (2 versus 3 days respectively), but overall the hospital stay was not significantly different. Postoperative analgesia requirements were reduced and return to normal activities and to work were faster after laparoscopic cholecystectomy. There was no significant cost difference between the two procedures.", "To analyze outcomes after open small-incision surgery (minilaparotomy) and laparoscopic surgery for gallstone disease in general surgical practice.\n This study was a randomized, single-blind, multicenter trial comparing laparoscopic cholecystectomy (LC) to minilaparotomy cholecystectomy (MC). Both elective and acute patients were eligible for inclusion. All surgeons normally performing cholecystectomy, both trainees under supervision and consultants, operated on randomized patients. LC was a routine procedure at participating hospitals, whereas MC was introduced after a short training period. All nonrandomized cholecystectomies at participating units during the study period were also recorded to analyze the external validity of trial results. The randomization period was from March 1, 1997, to April 30, 1999.\n Of 1,705 cholecystectomies performed at participating units during the randomization period, 724 entered the trial and 362 patients were randomized to each of the procedures. The groups were well matched for age and sex, but there were fewer acute operations in the LC group than the MC group. In the LC group 264 and in the MC group 150 operations were performed by surgeons who had done more than 25 operations of that type. Median operating times were 100 and 85 minutes for LC and MC, respectively. Median hospital stay was 2 days in each group, but in a nonparametric test it was significantly shorter after LC. Median sick leave and time for return to normal recreational activities were shorter after LC than MC. Intraoperative complications were less frequent in the MC group, but there was no difference in the postoperative complication rate between the groups. There was one serious bile duct injury in each group, but no deaths.\n Operating time was longer and convalescence was smoother for LC compared with MC. Further analyses of LC versus MC are necessary regarding surgical training, surgical outcome, and health economy.", "The effects of surgical trauma resulting from laparoscopic cholecystectomy and open cholecystectomy, were compared by assessing the postoperative acute phase alterations of selected plasma proteins, hormones and lymphocyte subpopulations in fifty-seven patients prior to elective cholecystectomy. Patients were prospectively randomized to undergo either laparoscopic cholecystectomy (n = 30) or open cholecystectomy (n = 27). Duration of operation and general anesthesia was similar in the two patient groups. The laparoscopic cholecystectomy patients had a shorter postoperative stay in hospital (3.1 (0.5) days vs. 7.1 (1.6) days; p < 0.001). In open cholecystectomy patients a significantly greater postoperative acute phase increase in plasma C-reactive protein (p < 0.001), cortisol (p < 0.05), and prolactin blood level (p < 0.001) was recorded. The postoperative acute phase decrease in the blood total-T-lymphocyte count (CD3 cells) and in the activated-lymphocyte count (OKDR cells) was significantly greater after open cholecystectomy (p < 0.05). These results, showing that acute phase responses are less marked after laparoscopic cholecystectomy than after open cholecystectomy, support the concept that the laparoscopic procedure is less traumatic.", "The aim of this study was to compare the cost of laparoscopic cholecystectomy with that of open cholecystectomy.\n We analyzed the cost of both procedures regarding hospital stay, days of work lost and the cost derived from the morbidity of the complications of each technique in two groups of patients. With these data we were able to calculate direct and indirect costs of both procedures and compare them.\n Morbidity was similar in both groups and had no influence in the cost; cost of the material used for laparoscopic cholecystectomy was higher; hospital stay and days of lost work were significantly lower for the laparoscopic procedure than for the open one. The total cost of laparoscopic cholecystectomy was 23% cheaper than that of open cholecystectomy.\n Laparoscopic cholecystectomy appears to be cheaper than open cholecystectomy. As the laparoscopic technique becomes more widespread its cost might decrease even further.", "Between August 1992 and July 1993, 27 patients aged 70 years of older with cholelithiasis were prospectively randomised into 2 groups. Fifteen patients underwent laparoscopic cholecystectomy and 12 patients underwent open cholecystectomy. Shorter operation time (93.3 +/- 25.3 minutes v. 176.3 +/- 26.1 minutes, P < 0.00001), fewer postoperative analgesic requirements (0.53 +/- 0.52 days v. 2.00 +/- 0.74 days, P < 0.00001), shorter postoperative hospital stay (3.93 +/- 1.71 days v. 7.92 +/- 0.79 days, P < 0.00001) and better cosmesis were found in the laparoscopic cholecystectomy group. The above data suggest that laparoscopic cholecystectomy is the treatment of choice for cholecystolithiasis in elderly patients.", "Laparoscopic cholecystectomy (LCCE) was gaining acceptance rapidly, when several institutions could demonstrate the safety of this minimal invasive treatment modality. Nevertheless prospective randomised studies still are missing to prove the advantages of this new treatment modality in contrast to open cholecystectomy. 77 patients with symptomatic cholelithiasis were treated by LCCE (n = 40) or mini-lap CCE (n = 37) in a prospective, randomised study. As preliminary results, there were no differences in duration of anesthesia and operation time, perioperative complications or postoperative need for analgetics. Patients with LCCE had significant less postoperative pain, less restriction of total vital capacity and a shorter postoperative hospital stay as parameters of a diminished operative trauma.", "The aim of this prospective randomized study was to define the optimum management between early and delayed laparoscopic cholecystectomy for patients with acute cholecystitis.\n Patients were randomized to receive either early laparoscopic cholecystectomy within 24 h of randomization or initial conservative treatment followed by delayed laparoscopic cholecystectomy 6-8 weeks later.\n There were 53 patients in the early group and 51 in the delayed group. There was no significant difference in conversion rate (early 21 per cent versus delayed 24 per cent), postoperative analgesic requirement (1 versus 2 doses) and postoperative complications. However, the early group had significantly longer operating time (122.8 versus 106.6 min, P = 0.04) and shorter total hospital stay (7.6 versus 11.6 days, P < 0.001).\n Early laparoscopic cholecystectomy is safe and feasible for acute cholecystitis with the additional benefit of shorter total hospital stay. Apart from a shorter operating time, treating patients with delayed laparoscopic cholecystectomy does not offer additional benefit.", "Laparoscopic cholecystectomy has been shown to allow better postoperative pulmonary function than open cholecystectomy, with less incidence of lung atelectasis. As atelectasis following abdominal surgery is responsible for most febrile episodes in the first 48 h, it was postulated that with minimally invasive surgery there may be a parallel improvement in the incidence of postoperative fever. This study was designed to evaluate this hypothesis. Seventy-eight patients were randomly divided into two groups. Thirty-eight had an open cholecystectomy and 40 underwent the laparoscopic approach. Twenty-one of the 38 patients (55%) following open cholecystectomy had early febrile episodes compared with only 6 of the 40 (15%) in the laparoscopic cholecystectomy group. We concluded that there was a lower incidence of febrile episodes following laparoscopic cholecystectomy and suggest that this was related to improved pulmonary function and minimal surgical trauma.", "Open cholecystectomy (OC) has been superseded by laparoscopic cholecystectomy (LC) for the treatment of cholelithiasis, although this fashion has not been validated by prospective studies. Our aim was to compare the two techniques.\n Prospective, randomised, open study.\n University hospital, Finland.\n 49 patients who required cholecystectomy for cholelithiasis confirmed by ultrasound.\n 49 patients were randomly allocated to LC (n = 27) or OC (n = 22): 25 and 22, respectively, eventually had the operation. LC was done using a four-trocar technique, and OC through a transverse right subcostal incision, as short as possible.\n Length of hospital stay and the duration of the sick leave were the primary outcome measures. Secondary outcome measures were: postoperative pain evaluated by visual analogue scale (VAS) and the need for opioids; pulmonary function measured by forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak flow velocity (PEFV), and arterial oxygen tension (PaO2), and endocrine stress measured by plasma catecholamines, cortisol and glucose concentrations.\n The median (range) hospital stay was significantly shorter after LC than OC, being 2.0 (1-15) compared with 4.5 (2-19) days p < 0.01. The duration of sick leave was also significantly shorter after LC than OC, being 14 (7-17) compared with 29 (4-34), p < 0.01. Patients had significantly less postoperative pain after LC than OC as reflected by the need for opioids. Pulmonary function and arterial oxygen tension deteriorated significantly less after LC than OC. The stress response was equal. There were three documented complications, one pneumonia after LC and two wound infections after OC.\n LC gives significantly better results in terms of less postoperative pain, better pulmonary function, better arterial oxygenation, and shorter hospital stay and duration of sick leave.", "We report a prospective randomised comparison between laparoscopic and small-incision cholecystectomy in 200 patients which was designed to eliminate bias for or against either technique.\n Patients were randomised in the operating theatre and anaesthetic technique and pain-control methods were standardised. Four experienced surgeons did both types of procedure. Identical wound dressings were applied in both groups so that carers could be kept blind to the type of operation.\n There was no significant difference between the groups for age, sex, body mass index, and American Society of Anaesthesiologists grade. Laparoscopic cholecystectomy took significantly longer than small-incision cholecystectomy (median 65 [range 27-140] min vs 40 [18-142] min, p<0.001). The operating time included operative cholangiography which was attempted in all patients. We found no significant difference between the groups for hospital stay (postoperative nights in hospital, median 3-0 [1-17] nights for laparoscopic vs 3-0 [1-14] nights for small-incision, p=0.74), time back to work for employed persons (median 5-0 weeks vs 4.0 weeks; p=0.39), and time to full activity (median 3-0 weeks vs 3.0 weeks; p=0.15).\n Laparoscopic cholecystectomy takes longer to do than small-incision cholecystectomy and does not have any significant advantages in terms of hospital stay or postoperative recovery.", "The fact that pulmonary complications occur in 20-60% of the patients subjected to abdominal operations clearly indicates that the lungs are the most endangered organ during the postoperative period.\n The aim of this study was to demonstrate the impact of cholecystectomy on postoperative respiratory disturbances by comparing the laparotomic cholecystectomy with laparoscopic gallbladder removal.\n A hundred cholecystectomized patients were included in the prospective randomized clinical trial. Half of the patients were operated on by the laparotomic procedure, whereas the other half underwent laparoscopic cholecystectomy. Spirometric parameters, arterial blood gases, and acid-base balance were determined before the operation, and at 6, 24, 72 and 144 h postoperatively. Abdominal distension was assessed by auscultating intestinal peristaltics, abdominal circumference measurement, and time interval to restitution of defecation.\n Six hours postoperatively, the values of ventilation parameters decreased on average by 40-50% from the baseline preoperative values in both groups of patients. The group of patients submitted to laparotomic cholecystectomy had significantly lower spirometric values and slower recovery of the ventilation parameters than the laparoscopic cholecystectomy group. Abdominal circumference was significantly greater and the time needed for restitution of peristaltics and defecation was significantly longer in the laparotomic cholecystectomy group compared to the group of laparoscopic cholecystectomy.\n Statistically significant impairments including hypoxia, hypocapnia and hyperventilation were observed in the patients submitted to laparotomic cholecystectomy, indicating the presence of objective respiratory risk, especially in elderly patients and patients with obstructive pulmonary diseases or cardiac insufficiency.\n Copyright 2000 S. Karger AG, Basel", "Although laparoscopic cholecystectomy has rapidly become routine practice in the UK, there has been no rigorous comparison of it with open cholecystectomy. In our trial, 302 patients were randomised to laparoscopic or minilaparotomy cholecystectomy. Recovery after surgery was assessed by length of hospital stay, outpatient review at 10 days and 4 weeks, and patient questionnaires 1, 4, and 12 weeks after surgery. The mean operation time was 14 min shorter for minilaparotomy, while median post-operative hospital stay was 2 days shorter after laparoscopic cholecystectomy. The hospital costs were about 400 pounds greater for the laparoscopic procedure. Laparoscopic patients returned to work in the home sooner; at 1 week, they had better physical and social functioning, were less limited by physical problems, and had less pain and depression. At 4 weeks, only physical functioning and depression scores were better in the laparoscopic group, and by 3 months there were no differences. Laparoscopic patients were more satisfied with the appearance of their scars. The incidence of complications after both procedures was 20%. Compared to minilaparotomy cholecystectomy, laparoscopic cholecystectomy results in shorter hospital stay, less postoperative dysfunction, and quicker return to normal activities, but is more costly.", "We investigated the effect of laparoscopic v open cholecystectomy on acute-phase reactants.\n Fifty patients were randomized to laparoscopic (Group 1) and 50 to open (Group 2) cholecystectomy. Preoperative and postoperative values for acute-phase reactants (ceruloplasmin, fibrinogen, Westergren sedimentation rate, alpha-1-antitrypsin, haptoglobin, and C-reactive protein) in blood samples were compared.\n Acute-phase reactants and length of hospitalization were significantly lower in patients who underwent a laparoscopic cholecystectomy than in those who underwent an open cholecystectomy.\n Laparoscopic cholecystectomy appears associated with a less intense stress response and less tissue damage than open cholecystectomy.", "Laparoscopic cholecystectomy (LC) has gained wide acceptance for treatment of cholelithiasis in preference to open cholecystectomy, though it has not been formally compared with mini cholecystectomy (MC). We have compared these two techniques in a randomised trial. 70 patients with ultrasound-proven cholelithiasis were randomly allocated LC (38) or MC (32); 37 and 25, respectively, underwent the assigned procedure. The mean hospital stay (including 1 preoperative day) was significantly shorter in the LC than the MC group (median 3 [interquartile range 2-3] vs 4 [3-5], p = 0.001) as was duration of convalescence (mean 11.9 [SD 9.1] vs 20.2 [16.5] days, p = 0.04). The rate of return to normal activities was 1.77 times greater in the LC group than in the MC group (95% confidence interval 1.01-3.11, p = 0.03). In regression analysis, the type of cholecystectomy done was the only variable significantly associated with the duration of convalescence. Although there was significant postoperative improvement in all of three quality of life scores in both groups, LC patients improved more quickly than did MC patients. This randomised trial shows the superior effectiveness of LC over MC in treating cholelithiasis.", "The positive CO2 pneumoperitoneum needed to create the working space for laparoscopic surgery induces cardiovascular, neuroendocrine, and renal changes. Concern about these pathophysiologic changes has led to the introduction of a gasless technique. Fifty consecutive patients with symptomatic gallstones were randomized to conventional (CLC) or gasless laparoscopic cholecystectomy (GLC), with special reference to overall patient satisfaction, technical difficulties, duration of surgery, postoperative pain, and recovery. The overall exposure of the operative field was extremely poor in the GLC group, whereas the duration of surgery, steps involved in the cholecystectomy technique, length of hospital stay, and postoperative pain score did not differ significantly. After discharge, the median time to complete relief of pain tended to be shorter in the gasless group (5 days [range 1 to 15]) vs. the conventional group (8 days [range 1 to 15]). The period to return to normal activity was shorter in the GLC group (6 days [range 1 to 15]) compared to the CLC group (8.5 days [range 1 to 15]) (P = 0.031). No differences were found in terms of fatigue, dizziness and nausea, and overall satisfaction with the outcome. This study demonstrates a significantly shorter convalescence after laparoscopic cholecystectomy by means of the gasless technique compared to the conventional CO2 technique. Exposure of the operative field was less than optimal using the gasless technique.", "Intraabdominal structures may be damaged during blind introduction of the first trocar for laparoscopic operations. In this study, 150 patients with gallbladder lithiasis who underwent laparoscopy were randomly assigned to two groups, a blind (V group) or an open (H group), in order to compare the results and the rate of complications. No mortality was observed. Major complications occurred in 3/75 (4%) patients of the V group and in 1/75 (1.3%) patient of the H group (p < 0.05). Minor complications occurred in 5/75 (6.7%) patients of either group. The achievement of pneumoperitoneum required 4.5+/-0.4 min in the V group and 3.2+/-0.2 min in the H group (p < 0.05). The open laparoscopic technique is safer and faster than the blind approach; therefore, it is proposed that this approach be routinely used in all laparoscopic procedures.", "The aim of the study was to calculate the hospital and social costs in relation to efficacy of clinical outcome, hospital stay and time off work in two groups of patients randomly treated with laparoscopic or mini-cholecystectomy. One hundred and eighty-one patients with simple, symptomatic gallstone disease were included in the study; of these, 9 cases were excluded because of conversion to conventional cholecystectomy. Eighty-six cases underwent laparoscopic cholecystectomy and 86 mini-cholecystectomy. Operative time (median time: 35 minutes) and hospital stay (median stay: 3 days) were the same for both surgical procedures. The median time off work was 10 days for laparoscopic cholecystectomy and 20 days for mini-cholecystectomy (P = 0.007). Hospital expenses showed a saving of 820.48 euros for each patient undergoing mini-cholecystectomy. Since laparoscopic cholecystectomy is associated with a shorter period off work, it seems to be cheaper with a daily saving of 164.96 and 146.51 Euros per patient, according to cost/effectiveness and cost/utility analyses, respectively. Consequently, although laparoscopic cholecystectomy shows a better outcome in terms of socioeconomic aspects and patient compliance, in an attempt to rationalize hospital expenditure, we would advocate mini-cholecystectomy for those patients who do not need to return to work early.", "The role of laparoscopic cholecystectomy for acute cholecystitis is not yet clearly established. The aim of this prospective randomized study was to evaluate the safety and feasibility of laparoscopic cholecystectomy for acute cholecystitis and to compare the results with delayed cholecystectomy.\n Between January 2001 and November 2002, 40 patients with a diagnosis of acute cholecystitis were assigned randomly to early laparoscopic cholecystectomy within 24 h of admission (early group, n = 20) or to initial conservative treatment followed by delayed laparoscopic cholecystectomy, 6 to 12 weeks later (delayed group, n = 20).\n There was no significant difference in the conversion rates (early, 25% vs delayed, 25%), operating times (early, 104 min vs delayed, 93 min), postoperative analgesia requirements (early, 5.3 days vs delayed, 4.8 days), or postoperative complications (early, 15% vs delayed, 20%). However, the early group had significantly more blood loss (228 vs 114 ml) and shorter hospital stay (4.1 vs 10.1 days).\n Early laparoscopic cholecystectomy for acute cholecystitis is safe and feasible, offering the additional benefit of a shorter hospital stay. It should be offered to patients with acute cholecystitis, provided the surgery is performed within 72 to 96 h of the onset of symptoms.", "Research confirms that laparoscopic cholecystectomy (LC) results in shorter lengths of hospital stay and earlier return to usual activity than the traditional cholecystectomy procedure. Research in this area, however, focuses more on the medical aspects of patient recovery, but very few studies have evaluated how these patients manage their recovery at home or what types of problems they encounter. A total of 28 LC patients were randomly assigned to two groups: (1) 23 h stay (overnight) in a general surgical ward or (2) day procedure unit (DPU) stay. Data was collected by a self-administered Postoperative Symptoms Diary and telephone interview. Results showed no significant difference between the two groups of patients recovery symptoms scores. Problems with mobility, pain and elimination recorded the highest mean scores for both groups of patients. Overnight patients also experienced problems with tiredness and eating. All DPU patients were able to manage their postoperative symptoms, compared to only 44% of patients who had stayed in overnight. Carer assistance was needed with regard to activities of daily living, child care and reassurance. Results showed that with careful selection of patients, LC cases performed as day procedures did not impact at all on the patients' recovery trajectory.", "Laparoscopic cholecystectomy is considered a minor surgical procedure. In a prospective, randomized study, we compared the metabolic responses to surgery in two groups of patients submitted to open or laparoscopic cholecystectomy. The aim of the study was to verify if the latter caused less metabolic changes. Blood samples were drawn before the operation (basal), 1 h and 2 h after skin incision, and on the first and second postoperative days. The following parameters were studied: cortisol, renin, and leukocytes, including subpopulations. The mean values for age, weight, height, basal neutrophil and lymphocyte counts, basal values of cortisol and renin of patients, and sex distribution of group 1 patients (open, n = 20) matched with those for group 2 (laparoscopic, n = 20), with the exception of age (p < 0.05). No differences were detected between the two groups in terms of cortisol and renin values. However, the neutrophil count 1 h after skin incision was statistically significantly higher with the laparoscopic approach (p < 0.05). The lymphocyte count on the second postoperative day was also statistically significantly higher in group 2 (p < 0.05). We conclude that when a cholecystectomy is performed, the laparoscopic approach has no advantage over the open approach from the standpoint of the metabolic responses we studied. It appears that leukocytes have a more rapid return to normal values after laparoscopic cholecystectomy. Although pneumoperitoneum is known to be responsible for important cardiorespiratory changes, no worse response was found in the laparoscopic group than in the open group.", "Cholecystectomy performed via laparotomy is associated with reduction of lung volumes including functional residual capacity that may lead to postoperative hypoxia and atelectasis. Laparoscopic cholecystectomy is associated with faster recovery compared to open laparotomy and cholecystectomy. To determine whether laparoscopic cholecystectomy was associated with less pulmonary dysfunction, 20 patients (ASA Physical Status I) undergoing elective cholecystectomy were randomly assigned to surgical teams performing either laparoscopy or open laparotomy for cholecystectomy. Patients in whom one or the other surgical technique had to be performed for medical or psychologic indications were excluded from the study. A standardized anesthetic technique and postoperative analgesic regimen were used. Forced vital capacity and forced expiratory volume in 1 s; functional residual capacity determined by a closed-circuit, constant volume helium dilution technique; and arterial O2 and CO2 tensions were measured preoperatively and at 6, 24, and 72 h postcholecystectomy. Forced vital capacity and forced expiratory volume in 1 s were significantly greater (P less than 0.05) in the laparoscopy compared to the laparotomy group at 6, 24, and 72 h postoperatively. Forced vital capacity relative to preoperative values was significantly (P less than 0.05) greater in patients with laparoscopy (24 h, 70 +/- 14%; 72 h, 91 +/- 6%) compared to open laparotomy (24 h, 57 +/- 23%; 72 h, 77 +/- 14%).

Only elective patients were eligible for inclusion. LC was a routine procedure at the institution in which the study was performed, whereas MLC was introduced after a short training period. The randomization period was from January to December 2001.\n Of 175 patients who had elective minimal access cholecystectomy during the randomization period, 135 entered the trial: 68 underwent LC and 67 underwent MLC. The groups were matched for age, sex and preoperative characteristics. Median (range) operating times for LC and MLC were similar (45 (20-120) and 50 (20-170) min respectively). Intraoperative and postoperative complication rates, the time for the patient to resume walking, eating and passing stools, and median hospital stay were the same in the two groups. The level of postoperative pain was lower in the MLC group at 1 h (P = 0.011), 3 h (P = 0.012), 6 h (P = 0.003), 12 h (P = 0.052) and 24 h (P = 0.034). Patients who had MLC received fewer injections of analgesic (P = 0.036) and more patients in this group expressed satisfaction with the cosmetic result (P = 0.001).\n MLC took a similar time to perform and caused less postoperative pain than the standard laparoscopic procedure. Reducing the port size further enhanced the advantages of laparoscopic over open cholecystectomy.\n Copyright 2003 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.", "To determine the feasibility and desirability of laparoscopic cholecystectomy (LC) in day-care versus LC with clinical observation.\n Laparoscopic cholecystectomy has been performed regularly as outpatient surgery in patients with uncomplicated gallstone disease in the United States, but this has not been generally accepted in Europe. The main objections are the risk of early severe complications (bleeding) or other reasons for readmission, and the argument that patients might feel safer when observed for one night. Quality-of-life differences hitherto have not been investigated.\n Eighty patients (American Society of Anesthesiology [ASA] I/II) with symptomatic gallstones were randomized to receive LC either in day-care or with clinical observation. Complications, (re)admissions, consultations of general practitioners or the day-care center within 4 days after surgery, use of pain medication, quality of life, convalescence period, time off from professional activities, and treatment preference were assessed. The respective costs of day-care and clinical observation were determined.\n Of the 37 patients assigned to the day-care group who underwent elective surgery, 92% were discharged successfully after an observation period of 5.7+/-0.2 hours. The remainder of the patients in this group were admitted to the hospital and clinically observed for 24 hours. For the 37 patients in the clinical observation group who underwent elective surgery, the observation time after surgery was 31+/-3 hours. Three patients in the day-care group and one patient in the clinical observation group had complications after surgery. None of the patients in either group consulted a general practitioner or the hospital during the first week after surgery. Use of pain medication was comparable in both groups over the first 48 hours after surgery. There were no differences in pain and other quality-of-life indicators between the groups during the 6 weeks of follow-up. Of the patients in the day-care group, 92% preferred day-care to clinical observation. The same percentage of patients in the clinical observation group preferred at least 24 hours of observation to day-care. Costs for the day-care patients were substantially lower (approximately $750/patient) than for the clinical observation patients.\n Effectiveness was equal in both patient groups, and both groups appeared to be satisfied with their treatment. Because no differences were found with respect to the other outcomes, day-care is the preferred treatment in most ASA I and II patients because it is less expensive.", "The discussion about laparoscopic appendectomy has increased since the introduction of this method. Randomized comparisons are still feasible, whereas this cannot be stated for other laparoscopic procedures (e.g., laparoscopic cholecystectomy). This randomized controlled trial included 170 patients. Open appendectomy was employed in 83 patients, and 87 were treated laparoscopically. The treatment groups were comparable regarding age, sex, Broca index, ASA classification, preliminary operations, and preoperative leucocytes. No statistically significant differences could be found with respect to surgical and general complications, operating time, consumption of analgesics and antibiotics, and return to work. The analysis revealed a statistically significant shorter hospital stay, a shorter time until return to normal physical activity, and a shorter duration of complaints for the laparoscopic group. We were unable to demonstrate any statistically significant advantage in using the open procedure.", "The main argument for laparoscopic cholecystectomy in preference to open cholecystectomy appears to be based on less traumatic incisions inflicted on the abdominal wall. To investigate the effects of different incision lengths on patients following elective open cholecystectomy, a randomized clinical study was conducted.\n In this study 130 patients were randomly assigned to undergo either open cholecystectomy through a transverse subcostal incision of mean length 5.8 cm, so called minicholecystectomy (65 patients), or to undergo conventional cholecystectomy through a paracostal incision of mean length 13.1 cm (65 patients). The perception of pain after operation was measured by a visual analogue scale. To register late complications the mean(s.d.) hospitalization period after operation was extended to 11.5(1.2) days in the minicholecystectomy group and 15.4(2.5) days in the conventional cholecystectomy group.\n The perceived pain and analgesic requirements were found to be similar in both groups. Twelve of 65 patients in the minicholecystectomy group and four of 65 in the conventional cholecystectomy group developed wound haematoma.\n On the basis of this prospective randomized study, the hypothesis that a smaller incision length on the abdominal wall could lower the level of perceived pain, and therefore decrease the postoperative analgesic intake after minicholecystectomy, could not be confirmed.", "To compare the outcome in early vs delayed laparoscopic cholecystectomy in terms of frequency of intra operative and postoperative complications and to determine the rate and reasons for conversion.\n A prospective randomized clinical trial was performed in the Department of Surgery at BP Koirala Institute of Health Sciences from February 2003 to June 2004 in all patients with the diagnosis of acute calculus cholecystitis.\n Out of 145 cases, 50 cases were included in our study where 12 (24%) patients were males and 38 (76%) were females (M:F=1:3.16). The mean (SD) age of patients in early and delayed groups were 42.68 yrs (14.18) and 40.26 yrs (11.62) respectively. The mean (SD) duration of symptoms in early successful and converted groups were 109.24 hrs (43.66) and 132 hrs (49.96) respectively and the mean (SD) duration of symptoms in delayed successful and converted groups were 15.36 months (13.88) and 41 months (40.73) respectively. In early group, 17 (68%) patients had total leukocyte count more than 10,000/cmm and they had ultrasound findings suggestive of acute cholecystitis. Out of 25 patients in early group, seven had jaundice and ten had deranged liver function in the preoperative period. In early group 4 (16%) patients; and in delayed group 3 (12%) had to be converted to open cholecystectomy (P=1.00). In early group 10 (40%) and in delayed 5 (20 %) cases had intraoperative complications (P=0.122). The total hospital stay was longer in the delayed group. The postoperative hospital stay in early and delayed converted groups were higher than early and delayed successful group (P=0.081, P=0.082).\n Both early and delayed laparoscopic cholecystectomy is possible and safe in the treatment of acute cholecystitis.", "To compare the effects and costs of an ambulatory treatment versus an overnight stay for laparoscopic cholecystectomy.\n Prospective, randomised.\n In the St Antonius hospital, Nieuwegein, the Netherlands, 86 patients with symptomatic cholelithiasis without comorbidity underwent either ambulatory (AM: 42 patients: 8 men and 36 women; mean age: 48.9 years (SD: 11.9)) or overnight stay (OS: 44 patients: 10 men and 32 women; mean age: 44.9 years (SD: 11.8)) laparoscopic cholecystectomy in the period 1 November 1997-30 September 1999. The following were registered: operative time, complications, hospital stay and readmissions, as well as reported pain, nausea, activity resumption, quality of life and patient satisfaction. The cost analysis was performed from a societal and hospital perspective.\n In the OS group one laparoscopic procedure was converted to open cholecystectomy, two relaparotomies were performed due to intra-abdominal haemorrhage and 1 patient had a catheter inserted due to urine retention. Two patients were readmitted, one for postoperative pancreatitis and the other for a retained bile duct stone. In the AM group one laparoscopic procedure was converted to open cholecystectomy, in 1 patient a wound abscess was treated with drainage in the outpatient clinic, in 1 patient there was peroperative stone loss without further complications and in 1 patient a catheter was placed to drain peroperative bile and blood loss. In the AM group 11 (26%) patients were kept overnight due to nausea and/or pain (n = 7) or one of the aforementioned complications (n = 4). Two patients were readmitted within 24 hours of being discharged due to abdominal pain. The average hospital stay was 3.1 (OS) versus 1.7 (AM) days. The quality of life, pain, nausea and activity resumption were comparable for both groups. Due to the difference in hospital stay, costs for the ambulatory procedure were lower.\n Laparoscopic cholecystectomy was successfully performed as an ambulatory surgery procedure in 69% of the patients. The quality of life, patient satisfaction and resumption of activities in both groups were comparable. The ambulatory treatment was less expensive.", "Laparoscopic cholecystectomy has been performed as a day-care procedure for many years. Few studies have been conducted with primary focus on patient acceptance and preferences in terms of quality of life for this practice compared with overnight stay.\n Data from 100 patients with symptomatic gallstones randomized to laparoscopic cholecystectomy performed either as a day-care procedure or with overnight stay were analysed. Complications, admissions and readmissions, quality of life and health economic aspects were assessed. Two instruments were used to assess quality of life, the Hospital Anxiety and Depression Scale (HADS) and the Psychological General Well-Being Index (PGWB).\n Forty-eight (92 per cent) of 52 patients in day-care group were discharged 4-8 h after the operation. Forty-two (88 per cent) of 48 in the overnight group went home on the first day after surgery. The overall conversion rate was 2 per cent. Two patients had complications after surgery, both in the day-care group. No patient in either group was readmitted. There was no significant difference in total quality of life score between the two groups. The mean direct medical cost per patient in the day-care group (3085 Euros) was lower than that in the overnight group (3394 Euros).\n Laparoscopic cholecystectomy can be performed as a day-case procedure with a low rate of complications and admissions/readmissions. Patient acceptance in terms of quality of life variables is similar to that for cholecystectomy with an overnight stay. The day-care strategy is associated with a reduction in cost.\n Copyright 2005 British Journal of Surgery Society Ltd.", "The aim of the study was to evaluate postoperative recovery after hand-assisted laparoscopic or open restorative proctocolectomy with ileal pouch anal anastomosis for ulcerative colitis and familial adenomatous polyposis in a randomized controlled trial.\n Sixty patients were randomized for hand-assisted laparoscopic (n = 30) or open surgery (n = 30). Primary outcome parameter was postoperative recovery in the 3 months after surgery, measured by quality of life questionnaires (SF-36 and GIQLI). Secondary parameters were postoperative morphine requirement and surgical parameters, viz. operating time, morbidity, hospital stay, and costs.\n There was no difference between the 2 procedures in quality of life assessment in the 3 months after surgery. There was a significant decline in quality of life on all scales of the SF-36 (P < 0.001) and total GIQLI score (P < 0.001) in the first 2 weeks in both groups (no significant difference between the groups). Quality of life returned to baseline levels after 4 weeks. Operating times were longer in the laparoscopic group compared with the open group (210 and 133 minutes, respectively; P < 0.001). No significant differences were found in morphine requirement. Neither morbidity nor postoperative hospital stay differed between the laparoscopic and open group (20% versus 17%, in 10 versus 11 days, respectively). Median overall costs were 16.728 for the hand-assisted laparoscopic procedure and 13.406 for the open procedure (P = 0.095).\n Recovery measured using quality of life questionnaires is comparable for hand-assisted laparoscopic or open restorative proctocolectomy with ileal pouch anal anastomosis. The laparoscopic approach is as safe, but more costly than the open procedure.", "A prospective randomized study was undertaken to compare early with delayed laparoscopic cholecystectomy for acute cholecystitis.\n Laparoscopic cholecystectomy for acute cholecystitis is associated with high complication and conversion rates. It is not known whether there is a role for initial conservative treatment followed by interval elective operation.\n During a 26-month period, 99 patients with a clinical diagnosis of acute cholecystitis were randomly assigned to early laparoscopic cholecystectomy within 72 hours of admission (early group, n = 49) or delayed interval surgery after initial medical treatment (delayed group, n = 50). Thirteen patients (four in the early group and nine in the delayed group) were excluded because of refusal of operation (n = 6), misdiagnosis (n = 5), contraindication for surgery (n = 1), or loss to follow-up (n = 1).\n Eight of 41 patients in the delayed group underwent urgent operation at a median of 63 hours (range, 32 to 140 hours) after admission because of spreading peritonitis (n = 3) and persistent fever (n = 5). Although the delayed group required less frequent modifications in operative technique and a shorter operative time, there was a tendency toward a higher conversion rate (23% vs. 11%; p = 0.174) and complication rate (29% vs. 13%; p = 0.07). For 38 patients with symptoms exceeding 72 hours before admission, the conversion rate remained high after delayed surgery (30% vs. 17%; p = 0.454). In addition, delayed laparoscopic cholecystectomy prolonged the total hospital stay (11 days vs. 6 days; p < 0.001) and recuperation period (19 days vs. 12 days; p < 0.001).\n Initial conservative treatment followed by delayed interval surgery cannot reduce the morbidity and conversion rate of laparoscopic cholecystectomy for acute cholecystitis. Early operation within 72 hours of admission has both medical and socioeconomic benefits and is the preferred approach for patients managed by surgeons with adequate experience in laparoscopic cholecystectomy.", "Elective laparoscopic cholecystectomy is established as the treatment of choice for symptomatic cholecystolithiasis and is now proposed for the treatment of acute cholecystitis. The aim of this study is to evaluate biochemical aspects of open (OC) and laparoscopic cholecystectomy (LC). We measured the levels of malondialdehyde (MDA) and the levels of nitrite+nitrate as stable end products of nitric oxide (NO). MDA and nitrite+nitrate levels were increased at both surgical procedures compared to preoperative period, but the rise was more significant in OC than LC. These results showed that both OC and LC caused an increase in oxidative stress. However LC caused significantly less oxidative stress and the changes during surgery returned to preoperative values after LC in a shorter period. The beneficial effects of laparoscopic surgery may be related, partially, to less oxidative stress in the immediate postoperative period.", "A prospective randomized study of laparoscopic versus open cholecystectomy was carried out fro December 1991 to June 1992 at the Chang Gung Memorial Hospital. Laparoscopic cholecystectomy was performed in 50 cases in group A and open cholecystectomy in 51 cases in group B. All patients had a preoperative history of biliary tract disease and most had gall stones proved by sonography. There was no operative mortality in either group and the postoperative complication rates were 4.4% and 2% in group A and B respectively (p > 0.05). Prolonged operative time in group A was 85.7 +/- 25.2 min vs group B 48.0 +/- 13.9 min (p < 0.001). Postoperative bowel function recovery with toleration of a regular diet in group A was faster than group B (45.6 +/- 19.2 hrs vs 55.2 +/- 11.0 hrs, p < 0.001).

[ "Results of trials of aspirin and dipyridamole combined versus aspirin alone for the secondary prevention of vascular events after ischaemic stroke of presumed arterial origin are inconsistent. Our aim was to resolve this uncertainty.\n We did a randomised controlled trial in which we assigned patients to aspirin (30-325 mg daily) with (n=1363) or without (n=1376) dipyridamole (200 mg twice daily) within 6 months of a transient ischaemic attack or minor stroke of presumed arterial origin. Our primary outcome event was the composite of death from all vascular causes, non-fatal stroke, non-fatal myocardial infarction, or major bleeding complication, whichever happened first. Treatment was open, but auditing of outcome events was blinded. Primary analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial (number ISRCTN73824458) and with (NCT00161070).\n Mean follow-up was 3.5 years (SD 2.0). Median aspirin dose was 75 mg in both treatment groups (range 30-325); extended-release dipyridamole was used by 83% (n=1131) of patients on the combination regimen. Primary outcome events arose in 173 (13%) patients on aspirin and dipyridamole and in 216 (16%) on aspirin alone (hazard ratio 0.80, 95% CI 0.66-0.98; absolute risk reduction 1.0% per year, 95% CI 0.1-1.8). Addition of the ESPRIT data to the meta-analysis of previous trials resulted in an overall risk ratio for the composite of vascular death, stroke, or myocardial infarction of 0.82 (95% CI 0.74-0.91). Patients on aspirin and dipyridamole discontinued trial medication more often than those on aspirin alone (470 vs 184), mainly because of headache.\n The ESPRIT results, combined with the results of previous trials, provide sufficient evidence to prefer the combination regimen of aspirin plus dipyridamole over aspirin alone as antithrombotic therapy after cerebral ischaemia of arterial origin.", "We report the results of a randomized multicenter clinical trial on the effects of aspirin plus dipyridamole versus placebo on major vascular end points in 231 non-insulin-dependent diabetic men with either a recent amputation for gangrene or active gangrene. Primary end points were death from atherosclerotic vascular disease plus amputation of the opposite extremity for gangrene. There were 24 atherosclerotic deaths in the drug treatment group (21.8%) and 23 in the placebo group (19.0%). There were 22 patients in the drug treatment group (20.0%) and 29 patients in the placebo group (24.0%) with opposite-side amputations. Survival curve analyses revealed little difference between these groups for major vascular end points, total mortality, all amputations, or myocardial infarctions. The most noteworthy group difference was observed for cerebrovascular end points (strokes and transient ischemic attacks), with an incidence of 8.2% (9 patients) in the drug treatment group and 19.0% (23 patients) in the placebo group. We conclude from this study that antiplatelet agents have no effect on the primary vascular end points, vascular deaths and/or amputation of the opposite extremity, in this population. Similarly, no effects were seen on secondary vascular end points, except for a suggestion of protection versus strokes and transient ischemic attacks. However, this finding must be interpreted with caution, since it is a secondary end point and was found only after multiple analyses of the data.", "604 Patients with atherothrombotic cerebral ischemic events (transient, 16%: or completed, 84%) referrable either to the carotid or to the vertebral-basilar circulation were entered into a double blind randomized clinical trial (AICLA) to determine whether aspirin (A) (1 g/day) or aspirin (1 g/day) + Dipyridamole (225 mg/day) (AD) would produce a significant reduction in the subsequent (3 years) occurrence of fatal and nonfatal cerebral infarction. Randomization produced remarkably comparable treatment groups and this good comparability was maintained throughout the study. Adherence to the protocol and drug compliance were excellent. Side effects, particularly symptoms of peptic ulcer and hemorrhagic events were significantly (p less than 0.03) more frequent in the two treatment groups containing aspirin. With the exception of patients who withdrew from the study, each patient was followed for 3 years. At the end of the study, the number of fatal and nonfatal cerebral infarctions was 31 in the placebo (P) group, 17 in the A group and 18 in the AD group. Taking into account the duration of follow-up for each patient, these figures correspond to cumulative rates of 18% in the P group and 10.5% in each of the 2 active treatment groups. Analysis with the Mantel Method showed: 1)--A difference at the 6% level between the 3 groups and between P and AD; 2)--A difference at the 5% level between P and A; 3)--No difference between (A and AD; 4)--A difference at the 2% level between the P group and the two treated groups taken together (A + AD). Among other diseases occurring during the trial, the only significant difference concerned myocardial infarction, which was less frequent in the 2 treated groups (P less than 0.05). Subgroup analysis failed to show a significant sex difference in the efficacy of aspirin. It is concluded that, in patients comparable to those defined in the protocol, Aspirin (1 g) has a significantly beneficial effect in the secondary prevention of atherothrombotic cerebral infarction.", "Low-molecular weight heparin has theoretical advantages over aspirin and dipyridamole in maintaining vascular-graft patency by virtue of its better antithrombotic effect and antiproliferative activity on vascular, smooth-muscle cells. We tested the hypothesis that low-molecular weight heparin would be more effective than aspirin and dipyridamole in maintaining graft patency in patients undergoing femoropopliteal bypass grafting. Patients were randomised to receive either a daily injection of 2500 IU low-molecular weight heparin, or 300 mg aspirin with 100 mg dipyridamole 8 hourly for 3 months. 94 patients were randomised to low-molecular weight heparin and 106 to aspirin and dipyridamole. Patients were stratified according to indication for surgery and were followed up for 1 year. Kaplan-Meier estimate of graft patency showed 87% graft survival on low-molecular-weight heparin and 72% on aspirin and dipyridamole at 6 months. At 12 months, the respective figures were 78% and 64%. Stratified survival analysis showed that this benefit was confined to those having salvage surgery (log rank test p = 0.0006); for those having surgery for claudication there was no significant benefit. No major bleeding events occurred in either group. We conclude that low-molecular weight heparin is better than aspirin and dipyridamole in maintaining femoropopliteal-graft patency in patients with critical limb ischaemia undergoing salvage surgery. This treatment should have considerable cost benefits.", "To evaluate the influence of antiplatelet drugs on patency in femoropopliteal vein bypasses, 48 vascular surgeons recruited 549 patients to a randomized double-blind trial of aspirin (300 mg) + dipyridamole (150 mg) or placebo twice daily starting 2 days before surgery and continuing indefinitely. Graft occlusion measured objectively by independent coordinators and cardiovascular events (myocardial infarction or stroke) were studied, expressed by life table, and analyzed statistically by log rank and confidence intervals (95% CI). Randomization achieved comparable groups with 60% of grafts inserted for rest pain or gangrene. Operative complications on aspirin plus dipyridamole included 18 reoperations for bleeding and 12 hematomas compared with 9 and 14, respectively, on placebo (NS). Most of the 172 graft failures occurred early with failure rates of 43/1000 patient-months in the first 3 months, reducing to 17/1000 at 6 to 12 months, and under 10/1000 in subsequent years. Cumulative graft patency on placebo was 72%, 62%, and 60% at 1, 2, and 3 years, respectively, compared with 78%, 70%, and 61% on aspirin plus dipyridamole. The difference in patency of 6.1% (95% CI, -3% to 15.5%) at 1 year and 8.0% (95% CI, -5% to 21%) at 2 years failed to achieve significance (p = 0.43). On mean follow-up of 34 months, 53 (132/1000 patient-years) cardiovascular events (myocardial infarction or cerebrovascular accident) occurred in patients on placebo compared with only 35 (73/1000) on aspirin plus dipyridamole, a significant difference of 59/1000 (p = 0.004). Antiplatelet therapy had little influence on femoropopliteal vein patency, but subsequent myocardial infarction and stroke was reduced in these patients with peripheral vascular disease.", "240 patients were admitted to a double-blind study to determine the effect of long-term treatment with platelet-function inhibiting agents on occlusive arterial disease in the lower extremities. Patients were randomised into 1 of 3 treatment groups: aspirin 330 mg; dipyridamole 75 mg and aspirin 330 mg; or matching placebo 3 times daily. The duration of treatment was 2 years. Arteriography was carried out at the beginning of the study and 2 years later or before if deterioration was observed. 199 patients completed the study according to the trial protocol. The serial arteriograms were assessed in pairs qualitatively, by means of simple comparative viewing, and semiquantitatively with Bollinger's score system. Progression of the disease was most pronounced in the placebo-treated group, less so in the aspirin-treated group, and least of all in the dipyridamole-and-aspirin group. Patients who smoke and those with hypertension may benefit most from treatment with the 2 preparations under investigation.", "Arteriovenous graft stenosis leading to thrombosis is a major cause of complications in patients undergoing hemodialysis. Procedural interventions may restore patency but are costly. Although there is no proven pharmacologic therapy, dipyridamole may be promising because of its known vascular antiproliferative activity.\n We conducted a randomized, double-blind, placebo-controlled trial of extended-release dipyridamole, at a dose of 200 mg, and aspirin, at a dose of 25 mg, given twice daily after the placement of a new arteriovenous graft until the primary outcome, loss of primary unassisted patency (i.e., patency without thrombosis or requirement for intervention), was reached. Secondary outcomes were cumulative graft failure and death. Primary and secondary outcomes were analyzed with the use of a Cox proportional-hazards regression with adjustment for prespecified covariates.\n At 13 centers in the United States, 649 patients were randomly assigned to receive dipyridamole plus aspirin (321 patients) or placebo (328 patients) over a period of 4.5 years, with 6 additional months of follow-up. The incidence of primary unassisted patency at 1 year was 23% (95% confidence interval [CI], 18 to 28) in the placebo group and 28% (95% CI, 23 to 34) in the dipyridamole-aspirin group, an absolute difference of 5 percentage points. Treatment with dipyridamole plus aspirin significantly prolonged the duration of primary unassisted patency (hazard ratio, 0.82; 95% CI, 0.68 to 0.98; P=0.03) and inhibited stenosis. The incidences of cumulative graft failure, death, the composite of graft failure or death, and serious adverse events (including bleeding) did not differ significantly between study groups.\n Treatment with dipyridamole plus aspirin had a significant but modest effect in reducing the risk of stenosis and improving the duration of primary unassisted patency of newly created grafts.

The European/Australasian Stroke Prevention in Reversible Ischaemia Trial (ESPRIT) aimed to determine whether oral anticoagulation with medium intensity is more effective than aspirin in preventing future vascular events in patients with transient ischaemic attack or minor stroke of presumed arterial origin.\n In this international, multicentre trial, patients were randomly assigned within 6 months after a transient ischaemic attack or minor stroke of presumed arterial origin either anticoagulants (target INR range 2.0-3.0; n=536) or aspirin (30-325 mg daily; n=532). The primary outcome was the composite of death from all vascular causes, non-fatal stroke, non-fatal myocardial infarction, or major bleeding complication, whichever occurred first. In a post hoc analysis anticoagulants were compared with the combination of aspirin and dipyridamole (200 mg twice daily). Treatment was open, but auditing of outcome events was blinded. Primary analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial (number ISRCTN73824458) and with ClinicalTrials.gov (NCT00161070).\n The anticoagulants versus aspirin comparison of ESPRIT was prematurely ended because ESPRIT reported previously that the combination of aspirin and dipyridamole was more effective than aspirin alone. Mean follow-up was 4.6 years (SD 2.2). The mean achieved INR was 2.57 (SD 0.86). A primary outcome event occurred in 99 (19%) patients on anticoagulants and in 98 (18%) patients on aspirin (hazard ratio [HR] 1.02, 95% CI 0.77-1.35). The HR for ischaemic events was 0.73 (0.52-1.01) and for major bleeding complications 2.56 (1.48-4.43). The HR for the primary outcome event comparing anticoagulants with the combination treatment of aspirin and dipyridamole was 1.31 (0.98-1.75).\n Oral anticoagulants (target INR range 2.0-3.0) are not more effective than aspirin for secondary prevention after transient ischaemic attack or minor stroke of arterial origin. A possible protective effect against ischaemic events is offset by increased bleeding complications.", "Aspirin is only modestly effective in the secondary prevention after cerebral ischemia. Studies in other vascular disorders suggest that anticoagulant drugs in patients with cerebral ischemia of presumed arterial (noncardiac) origin might be more effective. The aim of the Stroke Prevention in Reversible Ischemia Trial (SPIRIT) therefore was to compare the efficacy and safety of 30 mg aspirin daily and oral anticoagulation (international normalized ratio [INR] 3.0-4.5). Patients referred to a neurologist in one of 58 collaborating centers because of a transient ischemic attack or minor ischemic stroke (Rankin grade < or =3) were eligible. Randomization was concealed, treatment assignment was open, and assessment of outcome events was masked. The primary measure of outcome was the composite event \"death from all vascular causes, nonfatal stroke, nonfatal myocardial infarction, or nonfatal major bleeding complication.\" The trial was stopped at the first interim analysis. A total of 1,316 patients participated; their mean follow-up was 14 months. There was an excess of the primary outcome event in the anticoagulated group (81 of 651) versus 36 of 665 in the aspirin group (hazard ratio, 2.3; 95% confidence interval [CI], 1.6-3.5). This excess could be attributed to 53 major bleeding complications (27 intracranial; 17 fatal) during anticoagulant therapy versus 6 on aspirin (3 intracranial; 1 fatal). The bleeding incidence increased by a factor of 1.43 (95% CI, 0.96-2.13) for each 0.5 unit increase of the achieved INR. Anticoagulant therapy with an INR range of 3.0 to 4.5 in patients after cerebral ischemia of presumed arterial origin is not safe. The efficacy of a lower intensity anticoagulation regimen remains to be determined.", "Hemodialysis (HD) vascular access thrombosis remains a major cause of morbidity, accounting for 17.4% of all HD patient hospital admissions in 1986. We initiated this prospective, randomized, double-blind, placebo-controlled, parallel group study to examine if dipyridamole and/or aspirin decreased the rate of thrombosis of expanded polytetrafluoroethylene (ePTFE) grafts in HD patients. Two patient groups were studied: Type I--with a new ePTFE graft; and Type II--with thrombectomy and/or revision of a previously placed ePTFE graft. One hundred and seven patients were followed for 18 months or until the first thrombotic episode. Actuarial analysis of Type I patients showed cumulative thrombosis rates (mean +/- SEM) of 21 +/- 9% on dipyridamole alone, compared with 25 +/- 11% on dipyridamole and aspirin combination, 42 +/- 13% on placebo, and 80 +/- 12% on aspirin alone. The relative risk of thrombosis with dipyridamole was 0.35 (P = 0.02) and that for aspirin was 1.99 (P = 0.18). In Type II patients, the rate of thrombosis was high in all study drug and placebo groups (overall 78% thrombosis) and actuarial analysis was not carried out because of the small number of patients enrolled. We conclude that dipyridamole is beneficial in patients with new ePTFE grafts and that aspirin does not improve the risk of thrombosis in ePTFE grafts. Neither dipyridamole nor aspirin has any beneficial effect in patients with prior thrombosis of ePTFE grafts.", "Aprotinin (APR) reduces postoperative blood loss but may induce thrombosis. Dipyridamole (DIP) limits platelet aggregation and may reduce the thrombotic complications associated with APR.\n To evaluate the safety and effectiveness of combined APR and DIP, we undertook a prospective randomized trial in patients undergoing cardiac operations. Patients were stratified according to risk for bleeding (low or high), and received either DIP with placebo (DIP group; n = 59) or DIP with APR (DIP + APR group; n = 56). Blood samples were obtained for the measurement of hematologic and biochemical parameters. Blood loss and transfusion requirements were documented postoperatively.\n Postoperative blood loss and transfusion requirements were significantly lower in the DIP + APR group at 6, 12, and 24 hours after bypass (p < 0.01). No significant differences were found between groups in the incidence of perioperative mortality (DIP, 0%; DIP + APR, 3%), myocardial infarction (DIP, 0%; DIP + APR, 3%), stroke (DIP, 1%; DIP + APR, 1%), or potential thrombotic events (death, myocardial infarction, and stroke: DIP, 2%; DIP + APR, 5%). In addition, these rates did not differ from those of nonparticipating matched control patients.\n Administration of both drugs simultaneously was more effective than DIP alone in reducing postoperative blood loss. A platelet inhibitor may be required to reduce the thrombotic complications associated with APR. Further studies evaluating graft patency and perioperative ischemia are necessary to confirm the potential benefits of the combination of a platelet inhibitor and APR.", "Recent evidence has suggested that the delayed cerebral ischemic deficits that often follow surgery for aneurysmal subarachnoid hemorrhage (SAH) may be due to a proliferative vasculopathy. This vascular pathology may result from an interaction between the platelets and the vessel wall. A single-blind controlled trial of dipyridamole administration in 677 patients presenting with SAH (of whom 348 came to surgery) was undertaken to test the hypothesis that the modification of platelet behavior might reduce the incidence of ischemic deficits. Blind independent assessment of the outcome in the surgical group based on the Glasgow Outcome Scale and the specific neurological deficits revealed no significant differences between the control and treatment groups.", "Our aim was to determine the effect of short-term therapy with anti-platelet drugs on type-2 diabetic nephropathy for which a generally accepted therapy is missing.\n Seventy-six patients with type-2 diabetic nephropathy, who had normal renal function tests were randomized into the 4 groups; each group (n = 19) received one of the following treatments: aspirin (1000 mg), dipyridamole (750 mg), their combination or placebo daily for 2 months. Blood pressure, fasting blood sugar, serum electrolytes, creatinine clearance and 24 hours urine protein excretion rate was measured just before and at the end of the trial.\n Proteinuria and urinary protein: creatinine ratio decreased significantly in all 3 groups receiving aspirin and/or dipyridamole compared with the placebo group, also in each of those 3 groups comparing pre- and post-treatment values, while creatinine clearance rate, blood pressure, and blood sugar remained unchanged. At the end of the trial, the percentage proteinuria change was-15.9%,-14.8%,-37.3% and 1.9% in aspirin, dipyridamole, their combination and placebo groups respectively. The percentage proteinuria change had no positive correlation with demographic, clinical and laboratory findings but showed a strong positive correlation with mode of the therapy (r = 0.38, p = 0.0007). The percentage decline in proteinuria was significantly higher in the combination group than in the aspirin and dipyridamole groups. No side effects related to aspirin or dipyridamole was seen during the trial.\n Short-term trial of aspirin and/or dipyridamole significantly reduces proteinuria of type-2 diabetic nephropathy, with the most prominent effect seen with combination of the 2 drugs.", "To determine the effects of antiplatelet therapy among patients at high risk of occlusive vascular events.\n Collaborative meta-analyses (systematic overviews).\n Randomised trials of an antiplatelet regimen versus control or of one antiplatelet regimen versus another in high risk patients (with acute or previous vascular disease or some other predisposing condition) from which results were available before September 1997. Trials had to use a method of randomisation that precluded prior knowledge of the next treatment to be allocated and comparisons had to be unconfounded-that is, have study groups that differed only in terms of antiplatelet regimen.\n 287 studies involving 135 000 patients in comparisons of antiplatelet therapy versus control and 77 000 in comparisons of different antiplatelet regimens.\n \"Serious vascular event\": non-fatal myocardial infarction, non-fatal stroke, or vascular death.\n Overall, among these high risk patients, allocation to antiplatelet therapy reduced the combined outcome of any serious vascular event by about one quarter; non-fatal myocardial infarction was reduced by one third, non-fatal stroke by one quarter, and vascular mortality by one sixth (with no apparent adverse effect on other deaths). Absolute reductions in the risk of having a serious vascular event were 36 (SE 5) per 1000 treated for two years among patients with previous myocardial infarction; 38 (5) per 1000 patients treated for one month among patients with acute myocardial infarction; 36 (6) per 1000 treated for two years among those with previous stroke or transient ischaemic attack; 9 (3) per 1000 treated for three weeks among those with acute stroke; and 22 (3) per 1000 treated for two years among other high risk patients (with separately significant results for those with stable angina (P=0.0005), peripheral arterial disease (P=0.004), and atrial fibrillation (P=0.01)). In each of these high risk categories, the absolute benefits substantially outweighed the absolute risks of major extracranial bleeding. Aspirin was the most widely studied antiplatelet drug, with doses of 75-150 mg daily at least as effective as higher daily doses. The effects of doses lower than 75 mg daily were less certain. Clopidogrel reduced serious vascular events by 10% (4%) compared with aspirin, which was similar to the 12% (7%) reduction observed with its analogue ticlopidine. Addition of dipyridamole to aspirin produced no significant further reduction in vascular events compared with aspirin alone. Among patients at high risk of immediate coronary occlusion, short term addition of an intravenous glycoprotein IIb/IIIa antagonist to aspirin prevented a further 20 (4) vascular events per 1000 (P<0.0001) but caused 23 major (but rarely fatal) extracranial bleeds per 1000.\n Aspirin (or another oral antiplatelet drug) is protective in most types of patient at increased risk of occlusive vascular events, including those with an acute myocardial infarction or ischaemic stroke, unstable or stable angina, previous myocardial infarction, stroke or cerebral ischaemia, peripheral arterial disease, or atrial fibrillation. Low dose aspirin (75-150 mg daily) is an effective antiplatelet regimen for long term use, but in acute settings an initial loading dose of at least 150 mg aspirin may be required. Adding a second antiplatelet drug to aspirin may produce additional benefits in some clinical circumstances, but more research into this strategy is needed.", "In order to assess the usefulness of a combination of low-dose aspirin (25 mg b.i.d.) with dipyridamole (200 mg b.i.d.) in the prevention of major coronary events in patients with acute unstable angina, we performed a prospective, double-blind, placebo-controlled study involving 88 consecutive patients admitted to three Hospital Departments of Cardiology. The patients entered the study as soon as possible after hospital admission, and were treated and followed up to one year. There was no appreciable difference in side effects and adverse reactions between the treatment and control group. The incidence of cardiac death and/or nonfatal myocardial infarction during the whole period of observation was 14% (6/44) in the treatment group and 25% (11/44) in the placebo group by \"intention-to-treat\" analysis; 16% (4/25) and 32% (10/31), respectively, by \"drug-efficacy\" analysis (p = 0.21 by Fisher's exact test, non significant difference). However, when considering the only events occurred in the first month (2/44 in the treatment group and 9/44 in the placebo group, amounting to 4.5 and 20 percent, respectively), the combination of dipyridamole with low-dose aspirin reached a statistically significant protective effect (p = 0.04). The results of this pilot study provide strong evidence for a beneficial effect of the regimen tested in patients with acute unstable angina, at least in the first weeks of treatment, while at the same time suggesting a safe alternative for patients with contraindications to higher doses of aspirin.", "Recurrent stroke is a frequent, disabling event after ischemic stroke. This study compared the efficacy and safety of two antiplatelet regimens--aspirin plus extended-release dipyridamole (ASA-ERDP) versus clopidogrel.\n In this double-blind, 2-by-2 factorial trial, we randomly assigned patients to receive 25 mg of aspirin plus 200 mg of extended-release dipyridamole twice daily or to receive 75 mg of clopidogrel daily. The primary outcome was first recurrence of stroke. The secondary outcome was a composite of stroke, myocardial infarction, or death from vascular causes. Sequential statistical testing of noninferiority (margin of 1.075), followed by superiority testing, was planned.\n A total of 20,332 patients were followed for a mean of 2.5 years. Recurrent stroke occurred in 916 patients (9.0%) receiving ASA-ERDP and in 898 patients (8.8%) receiving clopidogrel (hazard ratio, 1.01; 95% confidence interval [CI], 0.92 to 1.11). The secondary outcome occurred in 1333 patients (13.1%) in each group (hazard ratio for ASA-ERDP, 0.99; 95% CI, 0.92 to 1.07). There were more major hemorrhagic events among ASA-ERDP recipients (419 [4.1%]) than among clopidogrel recipients (365 [3.6%]) (hazard ratio, 1.15; 95% CI, 1.00 to 1.32), including intracranial hemorrhage (hazard ratio, 1.42; 95% CI, 1.11 to 1.83). The net risk of recurrent stroke or major hemorrhagic event was similar in the two groups (1194 ASA-ERDP recipients [11.7%], vs. 1156 clopidogrel recipients [11.4%]; hazard ratio, 1.03; 95% CI, 0.95 to 1.11).\n The trial did not meet the predefined criteria for noninferiority but showed similar rates of recurrent stroke with ASA-ERDP and with clopidogrel. There is no evidence that either of the two treatments was superior to the other in the prevention of recurrent stroke.

Two hundred and twenty-three patients were included and followed. There were no differences between the groups regarding results 1, 3, 6 and 12 months following the dilatation treatment. It can be concluded that acetylsalicylic acid at the dose of 50 mg daily combined with dipyridamole does not seem to have a prophylactic effect after transluminal angioplasty during a follow-up period of 1 year.", "Patients (125) who had carotid transient ischemic attacks (TIAs) and one or more accessible carotid lesions visualized angiographically had reconstructive operations of the carotid artery and were then randomly assigned to aspirin or placebo treatment. The were followed to determine the incidence of subsecquent TIAs, death, cerebral infarction, or retinal infarction. Life table analysis (for 24 months follow up) that eliminated deaths which were not stroke-related revealed a significant difference in favor of aspirin. Because of the small number of patients and the short period of follow up, these results should be interpreted only as consistent with those reported in the initial publication but not conclusive of an aspirin effect in preventing cerebral infarction.", "To investigate whether anticoagulation or platelet inhibition treatment provides better prevention of reobstruction after percutaneous transluminal angioplasty (PTA).\n In a controlled study, 160 patients received either oral anticoagulants or a combination of low-dose acetylsalicylic acid (25 mg) and dipyridamole (200 mg) (ASAD) twice daily for 1 year after successful femoropopliteal PTA. Compliance was comparable. The patients in the two groups had similar clinical and angiographic characteristics. Patency was assessed with noninvasive methods 1 day and then 3, 6, and 12 months after PTA and was confirmed at angiography at the end of the study in 112 patients.\n Patency in patients who received anticoagulants was 53% and was not statistically significantly different from 69% in patients who received ASAD (P = .18). With anticoagulants, there were four bleeding complications (one was fatal); with ASAD, only five minor complications occurred.\n ASAD is at least as effective as anticoagulants for secondary prevention of obstruction after PTA but has less severe side effects." ]

Setting: Copenhagen, Denmark.\n 42 alcoholic patients without liver disease admitted for elective colorectal surgery.\n Withdrawal from alcohol consumption for 1 month before operation (disulfiram controlled) compared with continuous drinking.\n Postoperative complications requiring treatment within the first month after surgery. Perioperative immunosuppression measured by delayed type hypersensitivity; myocardial ischaemia and arrhythmias measured by Holter tape recording; episodes of hypoxaemia measured by pulse oximetry. Response to stress during the operation were assessed by heart rate, blood pressure, serum concentration of cortisol, and plasma concentrations of glucose, interleukin 6, and catecholamines.\n The intervention group developed significantly fewer postoperative complications than the continuous drinkers (31% v 74%, P=0.02). Delayed type hypersensitivity responses were better in the intervention group before (37 mm2 v 12 mm2, P=0.04), but not after surgery (3 mm2 v 3 mm2). Development of postoperative myocardial ischaemia (23% v 85%) and arrhythmias (33% v 86%) on the second postoperative day as well as nightly hypoxaemic episodes (4 v 18 on the second postoperative night) occurred significantly less often in the intervention group. Surgical stress responses were lower in the intervention group (P</=0.05).\n One month of preoperative abstinence reduces postoperative morbidity in alcohol abusers. The mechanism is probably reduced preclinical organ dysfunction and reduction of the exaggerated response to surgical stress." ]

[ "A prospective controlled, double-blind multicenter trial compared placebo, auranofin (an orally administered gold complex), and parenteral gold sodium thiomalate (GST) in patients with active rheumatoid arthritis (RA). Of 193 patients who received any treatment, the only important improvement identified for either auranofin or GST was for pain/tenderness scores. When 161 patients who completed 20 weeks of treatment were examined, both auranofin and GST treatments were superior to placebo as measured by improvement in number of painful and/or tender joints, joint pain/tenderness scores, physician's assessment of disease activity, and decrease in erythrocyte sedimentation rate when elevated at entry. GST was superior to placebo in improvement of joint swelling scores, anemia, thrombocytosis, and rheumatoid factor. No drug-related remissions were observed. The only statistically significant advantages of GST over auranofin for efficacy were an increase in hemoglobin concentration and decrease of thrombocytosis with GST. Withdrawals for adverse effects were 5 times more frequent with GST treatment. Thrombocytopenia, proteinuria, elevated liver enzymes, \"nitritoid\" reactions, and \"gold pneumonitis\" were observed only in the GST treatment group. These results confirm that both parenteral and oral gold may be effective for the treatment of RA, that GST tends to show greater efficacy than auranofin, and that auranofin has fewer significant adverse effects than GST.

[ "Children with airway malacia often have protracted courses of airway infections, because dynamic airway collapse during coughing results in impaired mucociliary clearance. The aim of this study was to determine the effect of the mucolytic drug recombinant human deoxyribonuclease (rhDNase) on the recovery of respiratory symptoms in children with airway malacia and lower respiratory tract infection (LRTI).\n In a randomized double-blind controlled clinical trial, 40 children with airway malacia and LRTI were randomly assigned to receive either 2.5 mg nebulized rhDNase or placebo twice daily for 2 weeks. The primary endpoint was the change in the cough diary score (CDS) (scale 0-5) from baseline to the second week of treatment. Secondary endpoints were VAS symptom scores for cough, dyspnea, and difficulty in expectorating sputum, need for an antibiotic course, and lung function data (FVC, FEV(1), FEF(75), R(int(e))).\n There was no significant difference in the mean change in CDSs from baseline between the rhDNase group and the placebo group (mean difference for daytime 0.19 (95% CI -0.53 to 0.90); for nighttime 0.38 (95% CI -0.30 to 1.05). Proportions of patients requiring antibiotics, and the mean changes in symptom scores and lung function from baseline did not significantly differ between both groups.\n Treatment with 2 weeks of nebulized rhDNase does not enhance recovery or reduce the need for antibiotics in children with airway malacia and LRTI.

Patients in both groups had similar risk factors. Genital cultures revealed an average of 3.0 isolates per specimen. Eighty-five aerobic gram-negative rods were isolated from 57 (48%) patients. All were susceptible to both aztreonam and gentamicin. Of 133 anaerobic isolates, 131 (98%) were susceptible to clindamycin. The failures in the aztreonam group were associated with a wound abscess and with an enterococcal bacteremia. Of the six failures in the gentamicin group, two were associated with persistent isolation of enteric bacilli. In the other four failures, no explanation was evident. Side effects occurred in four patients, (three diarrhea, one allergic reaction). All were self-limited and appeared to be due to clindamycin. No patient showed nephrotoxicity.

The results indicate that the clindamycin and gentamicin regimen is more efficacious in the treatment of severe infection after cesarean section than either ceftizoxime or cefoxitin regimens. Therefore, the results of this study suggest caution in substituting single drug antibiotic therapy with cefoxitin or the third generation cephalosporins for the standard clindamycin and gentamicin regimen in the treatment of postcesarean section endomyometritis until more clinical data are available.", "A random comparison of clindamycin-gentamicin (C-G) and penicillin-gentamicin was made in 200 women who developed endomyometritis following cesarean section.

The objective of this study was to evaluate the efficacy and safety of clindamycin and gentamicin in the management of endometritis vs. penicillin, chloramphenicol and gentamicin for 10 days. Sixty-five patients were enrolled and 62 were evaluable for efficacy. Both treatment groups were comparable in the pre-treatment period in terms of age, history of pregnancies, controls by gynecologist, days of disease and fever, clinical symptoms like fever, pelvic pain, pulse, uterine size and in laboratory, in hematocrit and leukocytes count. In the culture of endometrium tissue, 27/32 patients (84.4%) in Group A (penicillin + CAF + gentamicin) and 27/30 patients (90%) in Group B (clindamycin + gentamicin) had positive cultures at baseline; 18 and 22 patients showed anaerobes; 8 and 4 patients showed anaerobes plus aerobes and, one patient in each treatment group showed aerobes only. Peptostreptococcus and Bacteroides fragilis were the most frequently isolated pathogens. Improvement in lochia fetidity was more rapid in Group B, it turned transparent and not fetid since day 3. Complete cure was significantly better in Group B 24/30 (80%) in comparison with Group A 16/32 (50%) (p = 0.02). Partial response was found in 15 patients (43.3%) in Group A and 5 patients (16.6%) in Group B.

Patients are frequently cured clinically despite the fact that the offending organisms may be isolated in post-treatment cultures. Treatment of postcesarean endometritis without obtaining endometrial cultures is acceptable gynecologic practice. Obtaining post-treatment cultures is clearly not cost effective nor clinically beneficial. Drug treatment efficacy should be evaluated by clinical response.

The reduction in the incidence of endometritis was not reflected in the duration of hospital stay, which was 7.7 days in the untreated group, 7.8 days in the penicillin treated group, and 7.6 days in the clindamycin + gentamicin treated group. No significant differences between the groups were detected in the incidence of wound infections.", "The objective of the study was to evaluate the efficacy of gentamicin and clindamycin given once daily versus the more common 8-hour dosing regimen for the treatment of postpartum endometritis.\n In a prospective, placebo-controlled, double-blinded study, patients who had postpartum endometritis diagnosed were randomly selected to receive 1.5 mg/kg gentamicin and 900 mg clindamycin phosphate administered every 8 hours versus gentamicin 5 mg/kg and clindamycin phosphate 2700 mg administered as a single-daily dose. The single-dose group received an infusion of gentamicin and clindamycin, followed by an administration of intravenous placebo 8 and 16 hours later to maintain blinding. Treatment success was defined as absence of fever 72 hours after initiation of antibiotic therapy.\n One hundred ten patients were enrolled. The daily-dose group (n = 55) and the thrice-daily dose group (n = 55) were similar with respect to age, gravidity, parity, gestational age, and maternal weight. Clinical characteristics (including maximum temperature, presence of predelivery chorioamnionitis, white blood cell count, and mode of delivery) were also similar. There was no difference in the mean time from initiation of therapy until becoming afebrile in the daily-dose group (27.4 +/- 24.9 hours) compared with the thrice-daily dose group (32.9 +/- 26.3 hours). Forty-five of 56 (82%) patients in the daily-dose group and 38 of 55 (69%) patients in the thrice-daily dose group had treatment success (P =.12).\n Once-daily dosing with gentamicin and clindamycin in women with postpartum endometritis has a similar success rate as the standard every 8-hour dosing schedule.", "Sixty-two patients who had postpartum endometritis were treated with clindamycin in combination with either aztreonam or the aminoglycoside gentamicin.

Primary outcomes included cure rates, mean length of treatment, antibiotic-related charges, and nephrotoxicity. Multiple logistic regression analysis was used to control for confounding variables.\n There were 135 and 137 patients randomized to the experimental and conventional interval arms, respectively. Cures were obtained in 94.1% and 87.6% of patients in the experimental and conventional arms, respectively (p = 0.06). The experimental arm had mean antibiotic charges of $250.79 versus $442.49 in the conventional arm (p < 0.0001). There was no permanent nephrotoxicity in either group.\n Once-daily gentamicin dosing with twice-daily clindamycin dosing is as efficacious and safe as the thrice-daily dosing of gentamicin and clindamycin for peripartum uterine infection. The experimental regimen results in substantial cost savings. The incidence of nephrotoxicity is low.", "One hundred fifty-two women who received cefazolin prophylaxis and subsequently developed postpartum endometritis were randomized to treatment with either ticarcillin/clavulanic acid (75) or clindamycin-gentamicin (77). Bacteria isolated from the endometrium were predominantly facultative anaerobic bacteria. The ratio of facultative anaerobes to obligate anaerobes was 3:1. Nineteen percent of the women were bacteremic, with mycoplasma the organism most frequently isolated from venous blood specimens. Cure rates were similar for both groups: ticarcillin/clavulanic acid 85% and clindamycin-gentamicin 81%. The advantages of ticarcillin/clavulanic acid are an increased spectrum of activity against beta-lactamase-producing bacteria, less toxicity, and lower cost.", "Seventy-seven patients were prospectively enrolled in a randomized clinical trial to compare two antimicrobial regimens for the treatment of post-cesarean section endometritis. The two groups were not significantly different with respect to age, race, gravidity, parity, hours in labor, cesarean section indication, preoperative or postoperative hemoglobin/hematocrit, pretreatment white blood cell count or pretreatment temperature. Pretreatment urine, blood and endometrial cultures were obtained. One or more organisms was recovered from the endometrium in 90% of the patients using a double-lumen sampling device. The most frequent endometrial isolates were Peptostreptococcus and Bacteroides species, followed by Gardnerella vaginalis and enterococci. Thirty (81%) of 37 patients receiving ampicillin/sulbactam and 33 (83%) of 40 receiving gentamicin and clindamycin responded to therapy. There were 14 (18%) treatment failures, 7 in each group. Five (36%) of the 14 clinical failures were due to septic pelvic thrombophlebitis, 2 (14%) of the 14 failures were complications of intraabdominal abscesses, and the remaining 7 patients responded after a change in their antibiotic regimen. We conclude that ampicillin/sulbactam and clindamycin/gentamicin are similarly effective for the treatment of post-cesarean section endometritis.", "A new single-antibiotic combination of ticarcillin and clavulanic acid was compared with the standard two-drug regimen of clindamycin and gentamicin in the treatment of post-cesarean endomyometritis. The regimens were as follows: 3 g of ticarcillin plus 100 mg of clavulanic acid intravenously every four hours; or 600 mg of clindamycin intravenously every six hours plus 3 to 5 mg/kg per day of gentamicin intramuscularly. The prospective randomized schedule was calculated such that half the patients were assigned to each treatment group. The diagnosis of endomyometritis was based upon an elevated oral temperature of 100.4 degrees F or higher on any two occasions, excluding the first 24 hours after delivery, uterine tenderness, and the absence of other foci of infection. Lochial discharge was foul in most cases. Forty-seven patients were treated. Treatment was successful in all patients who received clindamycin and gentamicin; ticarcillin plus clavulanic acid failed in two of 23 (9 percent) patients. Patients in whom treatment failed did not appear to be different from those in whom treatment was successful on demographic variables or in terms of risk factors for endomyometritis. The difference between the treatment failure rates was not statistically significant. This study suggests that the single-drug combination of ticarcillin plus clavulanic acid is effective in the treatment of post-cesarean endomyometritis when compared with the standard regimen of clindamycin and gentamicin.", "This prospective study was designed to compare the relative efficacy of two antibiotic regimens for the treatment of operative site infections subsequent to pelvic operations. Patients with endomyoparametritis after delivery or pelvic cellulitis subsequent to hysterectomy were randomized to treatment with the combination of penicillin-gentamicin or the single agent cefoxitin. Seventeen of the 26 patients (65%) with endomyoparametritis who were treated with penicillin-gentamicin were cured by antibiotic therapy alone, in comparison to 15 of 23 (65%) patients treated with cefoxitin. Fifty-eight percent of the patients with pelvic cellulitis who were treated with penicillin-gentamicin responded favorably, in comparison to 50% of the patients treated with cefoxitin. None of these differences was statistically significant. In this study, neither antibiotic regimen provided satisfactory initial treatment for surgically induced soft tissue pelvic infection. Moreover, 11 of the 28 patients with treatment failures (40%) developed serious sequelae of their primary infection.", "Although intrapartum antibiotics are beneficial to both the mother and newborn, there is no consensus as to the most efficacious antibiotic regimen in the treatment of intra-amnionic infection, especially with regard to anaerobic coverage. We randomized pregnant women with intra-amnionic infection to receive either dual agent therapy (ampicillin and gentamicin) or triple agent therapy (ampicillin, gentamicin, and clindamycin). The frequency of vaginal and cesarean delivery was similar in both groups. There was no significant difference in the incidence of endometritis between the two groups (10 of 69 versus 5 of 64; p = NS). There were no significant differences in either neonatal morbidity or mortality. The addition of clindamycin to provide anaerobic coverage for intra-amnionic infection does not significantly alter the incidence of endometritis in women delivered by cesarean section, although it may have an impact on women delivering vaginally.", "Traditionally obstetric infections have been treated with combination antimicrobial agents that provide coverage against aerobic and anaerobic bacteria commonly found in these infections. New antibiotics may be a monotherapy alternative for this type of infections. The objective of the study was to compare the efficacy of the agent piperacillin/tazobactam against ampicillin plus gentamicin in the treatment of postcesarean endometritis. By randomized way 14 patients were enrolled in the piperacillin/tazobactam group and 42 in the ampicillin-gentamicin group. A favorable clinical response occurred in 78.6% of piperacillin/tazobactam patients and 88.1% of ampicillin and gentamicin patients (p = NS). There was no statistically significant difference in the times to recovery and days of hospitalization between the two groups. The combination piperacillin/tazobactam did not show advantage towards the standard treatment, so combination antimicrobial agent continue been the optimal approach to the management of obstetric infection.", "A randomized comparison of ceftazidime versus clindamycin-tobramycin was performed for the treatment of obstetrical and gynecological infections. Entry criteria were an oral temperature of greater than or equal to 38 degrees C and a clinical diagnosis of endometritis, salpingitis, or pelvic cellulitis after hysterectomy. All patients with endometritis had cultures of intrauterine material obtained via a transcervical single-lumen catheter. The patients with pelvic cellulitis had material from the vaginal apex aspirated for culture, and all patients with salpingitis had a culdocentesis for culture of intraperitoneal material. Of 38 patients who received ceftazidime, 34 had endometritis after cesarean section, 3 had endometritis after abortion, and 1 had pelvic cellulitis. Of 39 patients who received clindamycin-tobramycin, 35 had endometritis after cesarean section, 3 had salpingitis, and 1 had pelvic cellulitis. The most common bacterial isolates were Lactobacillus sp., Bacteroides bivius, Escherichia coli, other gram-negative aerobic bacilli, group B streptococci, and other aerobic streptococci. Bacteremia occurred in 9.0% of the patients. Of the patients receiving clindamycin-tobramycin and ceftazidime, 34 (87.2%) and 34 (89.5%), respectively, responded to therapy. All the clinical failures occurred in patients with endometritis after cesarean section. Clinical failures had persistent fever despite 3 or more days of treatment. One of the patients receiving clindamycin-tobramycin developed an urticarial rash after her infection had resolved. No patient in either group developed diarrhea. In these small groups of patients, there were no significant differences in cure rate, side effects, or length of hospital stay.", "To evaluate whether once-daily gentamicin dosing is as effective as the traditional 8-hour regimen for the treatment of postpartum endometritis.\n Postpartum women with endometritis were randomized to receive gentamicin 5 mg/kg as a single daily dose or 1.75 mg/kg every 8 hours. All subjects also received clindamycin. Each participant had a peak serum gentamicin level of at least 5.0 micrograms/mL within the first 24 hours. The dosing regimens were compared by analyzing the number of hours that patients were febrile, the length of hospital stay, occurrence of complications, pharmacy costs, and nursing time required to administer the regimens.\n The study group (n = 62) and the control group (n = 65) were similar in demographic characteristics and the presence of endometritis risk factors. No differences were found between the groups in the number of patients who completed therapy without complications, required changes in antibiotics, or required readmission for endometritis. The groups did not differ in the number of hours that patients remained febrile after the start of therapy or in the length of hospital stay. No patient in the study group had an initial peak serum concentration less than 5.0 micrograms/mL, whereas 24 patients in the control group had initial peak serum concentrations less than 5.0 micrograms/mL and required dose adjustment, a statistically significant difference (P < .001). Pharmacy costs averaged $16.12 +/- 5.68 for the study group and $41.75 +/- 17.41 for the control group, also a significant difference (P < .001). Nurse tasking time averaged 13.62 +/- 2.56 minutes for the study group and 28.06 +/- 8.77 minutes for the control group (P < .001).\n In patients with postpartum endometritis, once-daily gentamicin dosing provides consistently high peak serum levels of gentamicin, requires less nurse tasking time, costs less, and is as effective as the 8-hour dosing regimen.", "Cefoxitin, a cefamycin derivative, has demonstrated activity against a broad spectrum of aerobic and anaerobic bacterial pathogens. The efficacy and safety of cefoxitin were compared with that of the combination of clindamycin and gentamicin in the treatment of postcesarean section infection. Ninety-eight patients were evaluated. Cefoxitin cured 36 of 48 patients (75%); clindamycin/gentamicin cured 38 of 50 (76%) (P greater than .05). Febrile degree hours and length of hospital stay did not differ between the two study groups. No patient experienced abscess formation or septic pelvic thrombophlebitis. Both therapies were well tolerated. In the authors' experience, cefoxitin as a single agent was as effective in the treatment of postoperative pelvic infection as the combination of clindamycin and gentamicin.", "Sixty-eight patients with postpartum endomyometritis were enrolled in this open randomized comparative study. Forty-two patients received ampicillin/sulbactam and 26 received clindamycin. The cure rates were similar in the two groups: 83% in the ampicillin/sulbactam group and 88% in the clindamycin group. The most frequent endometrial bacterial isolates were Bacteroides bivius, Streptococcus faecalis, Escherichia coli, and Ureaplasma urealyticum. Bacteremia was present in 15 of 68 (22%), the most frequent isolates being Mycoplasma (four cases) and B bivius (three cases). Clindamycin-resistant species were S faecalis, E coli, and Proteus mirabilis. There were seven treatment failures in the ampicillin/sulbactam group; only one isolate (an E coli) was resistant to ampicillin/sulbactam. In a significant number of these failures, Mycoplasma was isolated. Ampicillin/sulbactam and clindamycin were found to be equally efficacious in the treatment of postpartum endometritis.", "A randomized, double-blinded, controlled clinical study of 84 patients with surgically treated gangrenous or perforated appendicitis was done to compare the efficacy of the combination of aztreonam, the first monobactam antibiotic, with gentamicin when either was combined with clindamycin. Fifty-six patients who were treated with aztreonam and clindamycin (A/C) and 28 patients who were treated with gentamicin and clindamycin (G/C) fulfilled criteria for evaluation. A matched historic control group of 56 G/C patients was also included for comparison. All measures of outcome, including days of fever, hospitalization, antibiotic therapy, and the incidence of antibiotic failures, were similar. It was concluded that aztreonam was as effective as gentamicin in this study and may offer some advantages with regard to toxicity and serum drug level monitoring.", "This study compared the safety and efficacy of cefoperazone plus sulbactam with that of clindamycin plus gentamicin in the treatment of intra-abdominal infection. Seventy-six patients were included in the analysis of an open, randomized, comparative, single-site trial. Forty-seven patients received cefoperazone-sulbactam, and 29 patients received clindamycin plus gentamicin. Thirty-three patients (70%) who received cefoperazone-sulbactam and 15 patients (52%) who received clindamycin plus gentamicin were cured of infection, did not suffer a relapse within one month after the end of treatment, and did not receive any other antibiotics during the follow-up period (P = 0.17). In patients treated with cefoperazone-sulbactam there were four cases of superinfection, one patient had a prolonged prothrombin time, six patients had a poor response, two patients received antibiotics during follow-up, and one patient died during follow-up because of cancer. Treatment with clindamycin plus gentamicin was associated with five cases of superinfection, four patients had a poor response, four patients had a drug reaction, and one patient required antibiotics in the follow-up period. Serum levels of cefoperazone-sulbactam measured at one and three hours after dosing were consistent with earlier findings in normal volunteers. Two hundred and one pathogens were isolated, and 17 of 122 aerobic isolates (14%) were resistant to cefoperazone-sulbactam, and 17 of 122 (14%) were resistant to both clindamycin and gentamicin. Eleven of 79 (14%) anaerobic isolates were resistant to cefoperazone, none was resistant to cefoperazone-sulbactam, and 10 of 79 (13%) were resistant to clindamycin. The results of this study show that cefoperazone-sulbactam is an effective and safe alternative to clindamycin plus gentamicin in the treatment of intra-abdominal infections.", "In the course of two consecutive, double-blind and prospective studies, the authors evaluated the prophylactic effect of a single peroperative intravenous dose of gentamicin (this study included 166 patients) or the combination gentamicin and clindamycin (this study included 127 patients), on the wound infection rate following interventions involving the incision of an abdominal hollow viscus. Antibiotic prophylaxis lowered the post-operative wound sepsis rate, especially following clinically contaminated interventions, but this reduction did not reach statistical significance. It is concluded that a single peroperative parenteral dose of antibiotics does not constitute an entirely satisfactory means of wound infection prophylaxis in digestive surgery.", "The direct and indirect costs associated with either moxalactam or clindamycin plus gentamicin as treatment for endomyometritis after emergent cesarean section were compared in an open, randomized prospective trial of 114 patients. A total of 58 patients were assigned to receive moxalactam, 2 g intravenously (i.v.) every 8 h for 5 doses, followed by 2 g every 12 h and prophylactic vitamin K (10 mg) intramuscularly, and 56 patients were assigned to receive clindamycin (600 mg) i.v. every 6 h plus gentamicin (1.5 mg/kg) i.v. every 8 h. Prothrombin times were measured in moxalactam-treated patients, and patients treated with clindamycin plus gentamicin had urinalyses and blood urea nitrogen and serum creatinine determinations performed before and after treatment. Also, gentamicin levels in serum were determined as clinically indicated. A satisfactory treatment response was defined as the resolution of signs and symptoms of endomyometritis within 3 days of the start of antibiotic therapy. Satisfactory responses were demonstrated in 78% of the moxalactam-treated patients and 84% of patients treated with clindamycin plus gentamicin. Mean hospital costs for laboratory tests ($30.30 versus $4.53) and mean patient charges for laboratory tests ($76.39 versus $27.81) and medications ($539.45 versus $421.82) were significantly higher in patients treated with clindamycin plus gentamicin (P less than 0.05), while mean medication costs to the hospital were greater in the moxalactam group ($255.47 versus $195.68; P less than 0.05). However, total patient charges and total hospital drug-associated costs were not significantly different for the two group. In this tudy, moxalactam was similar in efficacy and, despite its higher acquistion cost, was comparable in total hospital costs and patient charges to clindamycin plus gentacmicin in treating endomyometritis.", "To evaluate the safety and efficacy of an abbreviated course of antibiotic therapy in postpartum endomyometritis, 109 patients with endomyometritis were randomized to three study groups. All were treated with clindamycin and tobramycin until afebrility and clinical signs of disease were absent. Patients in group I received antibiotics for greater than or equal to 24 hours, group II received therapy for greater than or equal to 48 hours, and group III received antibiotic therapy for greater than or equal to 48 hours that preceded a 7-day course of oral Augmentin. The groups were similar in size and in demographic and clinical parameters. Two patients from each group required a third antibiotic, and no patient required rehospitalization. Group III required more days of antibiotic therapy than did group I, 2.9 versus 2.1 days (p less than 0.01), and cost $412.00 more per patient. This data strongly suggest that a short course of antibiotic therapy is efficacious and safe and would result in substantial monetary savings.", "Sixty women with the diagnosis of puerperal endometritis were randomized to receive either moxalactam (n = 29) or the combination of clindamycin and tobramycin (n = 31) as therapy for their infection. Endometrial bacteriology consisted of mixed flora, both aerobic and anaerobic gram-positive and gram-negative organisms. Clinical cure was achieved in 27 (93%) of the moxalactam-treated patients and 28 (90%) of those given combination therapy. The two failures of moxalactam therapy were associated with enterococcal infection. Failures of clindamycin/tobramycin therapy were due to enterococcal infection, abscess formation, and moderately severe diarrhea. This study indicates that moxalactam is as effective and safe as the combination of clindamycin/tobramycin for the treatment of postpartum endometritis.", "The purpose of this study was to compare the efficacy and side effects of erythromycin, amoxicillin, and clindamycin in eradicating Chlamydia trachomatis from the lower genital tract of pregnant women.\n A total of 174 women at <36 weeks gestation with positive cervical cultures for C. trachomatis were enrolled. Patients were assigned in a randomized prospective fashion to either erythromycin (500 mg q.i.d, for 7 days), amoxicillin (500 mg t.i.d, for 7 days), or clindamycin (600 mg t.i.d, for 10 days). Six women elected not to participate and 8 patients were lost to follow-up, leaving 53 patients in the erythromycin group, 55 patients in the amoxicillin group, and 52 patients in the clindamycin group. All sexual partners of the enrolled women were offered doxycycline (100 mg b.i.d. for 7 days) and patients were instructed to use barrier contraception until treatment was complete.\n All 3 medications were effective agents for the treatment of antenatal C. trachomatis infection with treatment efficacies of 96%, 94%, and 98% for the erythromycin, amoxicillin, and clindamycin groups, respectively. When the antibiotic groups were compared, no statistically significant differences were noted in intolerance. However, the differences in the incidence of gastrointestinal symptoms between erythromycin and amoxicillin and/or clindamycin were significant (P < 0.05).\n These findings suggest that 1) all 3 antibiotic regimens are efficacious, 2) erythromycin has a higher incidence of side effects, and 3) amoxicillin or clindamycin are reasonable alternatives for the treatment of C. trachomatis in pregnant patients unable to tolerate erythromycin.", "Many antibiotics and antibiotic combinations are used for the treatment of peritonitis because of advanced (gangrenous or perforated) appendicitis. An aminoglycoside combined with an antianaerobe antibiotic is one standard treatment, but there is concern about the potential nephrotoxicity of the aminoglycoside and the necessity for monitoring aminoglycoside blood levels. Cefepime, a new broad-spectrum cephalosporin with a prolonged serum half-life, has excellent activity against gram-positive and gram-negative bacteria, including Pseudomonas aeruginosa. Its spectrum of activity is similar to the aminoglycosides, but it has less potential for inducing renal injury. A double-blind, randomized study compared cefepime, 2 grams every 12 hours IVPB plus metronidazole 0.5 grams every eight hours IVPB (C/M) with gentamicin 1.5 milligrams per kilograms of IVPB plus clindamycin 0.9 grams q eight hours IVPB (G/C), administered up to 14 days, in 96 surgically treated patients with gangrenous or perforated appendicitis. Fifty patients had advanced appendicitis (nine gangrenous and 41 perforated) in the C/M group and 46 patients (six gangrenous and 40 perforated) in the G/C group. The mean number of days of postoperative fever (C/M, 4.4 +/- 2.7 versus G/C, 5.0 +/- 2.2), postoperative hospitalization (C/M, 2.0 +/- 1.9 versus G/C, 2.0 +/- 2.1) and antibiotic therapy (C/M, 6.3 +/- 1.9 versus G/C, 6.9 +/- 1.9) was similar in the two treatment groups. There were 11 treatment failures (C/M, three; G/C, eight; p = 0.13), six of which were probably a result of enterococci. No deaths occurred. Our study results show that the efficacy of cefepime plus metronidazole is equivalent to that of clindamycin plus gentamicin." ]

[ "To compare the Burch colposuspension and the anterior colporrhaphy in women with both stress urinary incontinence and advanced anterior vaginal wall prolapse (cystocele).\n Prospective randomised study.\n Secondary referral centre, Urogynaecology Unit, San Gerardo Hospital, Monza, Italy.\n Seventy-one women undergoing surgery for primary genuine stress incontinence and concurrent grade 2 or 3 cystocele (descending at or outside the vaginal introitus).\n Full urodynamic investigation performed pre-operatively and repeated six months after surgery. Clinical follow up continued for 8 to 17 years.\n Subjective (patient history) and objective (negative stress test result) cure of stress incontinence. Assessment of cystocele recurrence.\n Thirty (86%) of the 35 evaluable women who had the Burch colposuspension and 17 (52%) of the 33 evaluable women who had the anterior colporrhaphy were subjectively cured (OR 5.6, 95% CI 1.6 to 21.6; P = 0.005). Objective cure rates were 74% (26 of 35) and 42% (14 of 33), respectively (OR 3.9, 95% CI 1.3 to 12.5; P = 0.02). A recurrent cystocele of grade 2 or 3 with or without prolapse at other vaginal sites was recorded in 34% (12 of 35) and 3% (1 of 33) of women, respectively (OR 16.7, 95% CI 2.0 to 368.1; P = 0.003).\n The Burch colposuspension was better in controlling stress incontinence but it lead to an unacceptable high rate of prolapse recurrence. The anterior colporrhaphy was more effective in restoring vaginal anatomy but it was accompanied by an unacceptable low cure rate of stress incontinence. Neither of the two operations is recommended for women who are suffering from a combination of stress incontinence and advanced cystocele.", "The use of standardized mesh kits for repair of pelvic-organ prolapse has spread rapidly in recent years, but it is unclear whether this approach results in better outcomes than traditional colporrhaphy.\n In this multicenter, parallel-group, randomized, controlled trial, we compared the use of a trocar-guided, transvaginal polypropylene-mesh repair kit with traditional colporrhaphy in women with prolapse of the anterior vaginal wall (cystocele). The primary outcome was a composite of the objective anatomical designation of stage 0 (no prolapse) or 1 (position of the anterior vaginal wall more than 1 cm above the hymen), according to the Pelvic Organ Prolapse Quantification system, and the subjective absence of symptoms of vaginal bulging 12 months after the surgery.\n Of 389 women who were randomly assigned to a study treatment, 200 underwent prolapse repair with the transvaginal mesh kit and 189 underwent traditional colporrhaphy. At 1 year, the primary outcome was significantly more common in the women treated with transvaginal mesh repair (60.8%) than in those who underwent colporrhaphy (34.5%) (absolute difference, 26.3 percentage points; 95% confidence interval, 15.6 to 37.0). The surgery lasted longer and the rates of intraoperative hemorrhage were higher in the mesh-repair group than in the colporrhaphy group (P<0.001 for both comparisons). Rates of bladder perforation were 3.5% in the mesh-repair group and 0.5% in the colporrhaphy group (P=0.07), and the respective rates of new stress urinary incontinence after surgery were 12.3% and 6.3% (P=0.05). Surgical reintervention to correct mesh exposure during follow-up occurred in 3.2% of 186 patients in the mesh-repair group.\n As compared with anterior colporrhaphy, use of a standardized, trocar-guided mesh kit for cystocele repair resulted in higher short-term rates of successful treatment but also in higher rates of surgical complications and postoperative adverse events. (Funded by the Karolinska Institutet and Ethicon; ClinicalTrials.gov number, NCT00566917.).", "Eighty-one women with clinical and urodynamic findings of genuine stress incontinence and genital prolapse were randomly selected to be surgically treated with either anterior colporrhaphy or Burch colposuspension. Each patient had a complete clinical and urodynamic evaluation before surgery and at 2 months and 3 years after surgery. Differences in cure rates between the two procedures at the 2-month post-operative evaluation were insignificant; however, at the 3-year post-surgical evaluation, the cure rate of women who had undergone Burch colposuspension was significantly higher than that of women who had undergone anterior colporrhaphy (cure rates were 88% and 57%, respectively; P < 0.001). The Burch colposuspension was more effective than the anterior colporrhaphy in the stabilization of the bladder base, neck and proximal urethra as confirmed by transvaginal sonography. Post-operative spontaneous voiding was uneventful in both procedures. Results of this study demonstrate that the Burch colposuspension in our hands was more effective in treating genuine stress incontinence and pelvic relaxation than was anterior colporrhaphy.", "Severe prolapse may mask potential genuine stress urinary incontinence in women. Some have suggested that a suspending urethropexy be performed in women who have potential genuine stress incontinence demonstrated by barrier reduction of the prolapse preoperatively. Our aim was to compare outcomes after prolapse surgery that included a formal bladder neck suspension with those operations that did not.\n This prospective randomized clinical trial assigned 32 women with bladder neck hypermobility and stage III or IV pelvic organ prolapse to receive either a needle colposuspension or bladder neck endopelvic fascia plication as part of the vaginal reconstructive surgery. Twenty-nine subjects underwent detailed clinical, anatomic, urodynamic, and quality-of-life evaluations before and 6 weeks and 6 months after surgery; 23 completed urinary diary and quality-of-life evaluations after a mean of 2.9 years.\n Needle colposuspension increased short-term complications without providing additional protection from de novo stress incontinence. Barrier testing before surgery predicted urethral sphincteric resistance after surgery; however, such testing neither predicted a patient's function after surgery nor indicated the need for a suspending urethropexy. The combination of a needle colposuspension with a sacrospinous ligament suspension predisposed to the early development of support defects of the upper anterior vaginal segment and to failure of bladder neck support.\n Preoperative barrier testing in women with severe prolapse is not useful in identifying individuals who require a suspending urethropexy. Needle colposuspension increases short-term complications, lacks durability, and may predispose to early and severe recurrent anterior prolapse when performed with a sacrospinous ligament vault suspension.", "This study aims to compare the result of an incontinence procedure performed at the time of prolapse repair or 3 months later in women with pelvic organ prolapse (POP) and stress urinary incontinence (SUI).\n In a multicenter prospective randomized trial, women with POP and SUI were randomized to have a tension-free vaginal tape (TVT) at the time of prolapse repair (n = 87; group I) or 3 months later (n = 94; group II). Women in group II were evaluated for SUI 3 months after the prolapse repair. Those with confirmed SUI had a TVT performed (n = 53). The main evaluation of all women was 1 year after the last surgery.\n On-treatment analysis resulted in 95% cure of SUI in group I and 89% in group II (p = 0.12). Twenty-seven percent were cured after prolapse surgery alone.\n No differences were found between the two treatment strategies, but almost one third of women were cured of SUI by prolapse surgery alone.", "In a randomized trial, we compared the success of Burch retropubic urethropexy to the modified anterior colporrhaphy for the treatment of genuine stress urinary incontinence.\n Thirty-five patients with stress incontinence were randomly assigned to undergo Burch retropubic urethropexy or modified anterior colporrhaphy. Subjects had preoperative and 1-year postoperative physical examinations, multichannel urodynamic testing, 20-minute pad test, and subjective grading of incontinence severity with questionnaires. Data were evaluated using Fisher exact test, Wilcoxon two-sample test, logistic regression analysis, and analysis of variance.\n Objective cure 1 year postoperatively was significantly greater for the women treated by Burch retropubic urethropexy than by modified anterior colporrhaphy (16 of 18 [89%] versus five of 16 [31%], relative risk .15, 95% confidence interval .04, .59). Patients' subjective ratings of incontinence severity 1 year after surgical treatment were significantly lower in women who had Burch retropubic urethropexy.\n Burch retropubic urethropexy yields a significantly superior objective cure for genuine stress urinary incontinence than the modified anterior colporrhaphy in a randomized trial." ]

[ "Mycoplasma pneumoniae is known to be a major cause of lower respiratory tract infections (LRTIs) in children. We studied 75 children who had been hospitalized for community-acquired LRTIs for the detection of M. pneumoniae by serological analysis and polymerase chain reaction (PCR) to amplify a 277-base pair region of 16S rDNA gene of M. pneumoniae applied to throat swab specimens. Serological and/or PCR positive results diagnosed M. pneumoniae infection in 23 (30.7%) patients.", "In order to evaluate the role of Mycoplasma pneumoniae and Chlamydia pneumoniae, we studied 613 children aged 2-14 years who were hospitalized for community-acquired lower respiratory tract infections (LRTIs). The patients were enrolled in the study by 21 centers in different regions of Italy from May 1998 through April 1999. Paired serum samples were obtained on admission and after 4-6 weeks to assay the titers of M. pneumoniae and C. pneumoniae antibodies. Nasopharyngeal aspirates for the detection of M. pneumoniae and C. pneumoniae were obtained on admission. Acute M. pneumoniae infections in 210 patients (34.3%) and acute C. pneumoniae infections in 87 (14.1%) were diagnosed. Fifteen of the 18 children with M. pneumoniae and/or C. pneumoniae infections whose treatments were considered clinical failures 4-6 weeks after enrollment had not been treated with macrolides.

Our data underline the role of M. pneumoniae in Indian children with community-acquired LRTIs even in children aged < 24 months.", "Inappropriate use of antibiotics is common in primary care, and effective interventions are needed to promote judicious antibiotic use and reduce antibiotic resistance. The objective of this study was to assess the impact of parent and clinician education on pediatric antibiotic prescribing and carriage of penicillin-nonsusceptible Streptococcus pneumoniae in child care facilities.\n A nonrandomized, controlled, community intervention trial was conducted in northern Wisconsin Clinicians. Clinic staff received educational materials and small-group presentations; materials were distributed to parents through clinics, child care facilities, and community organizations. Prescribing data were analyzed for 151 clinicians who provided primary pediatric care; nasopharyngeal carriage of penicillin-nonsusceptible S pneumoniae was assessed for 664 children in the baseline period (January-June 1997) and for 472 children in the postintervention period (January-June 1998).\n The median number of solid antibiotic prescriptions per clinician declined 19% in the intervention region and 8% in the control region. The median number of liquid antibiotic prescriptions per clinician declined 11% in the intervention region, compared with an increase of 12% in the control region. Retail antibiotic sales declined in the intervention region but not in the control region. Among participating children in child care facilities, there were no significant differences in antibiotic use or penicillin-nonsusceptible S pneumoniae colonization between the intervention and control regions.\n A multifaceted educational program for clinicians and parents led to community-wide reductions in antibiotic prescribing, but in child care facilities, there was no apparent impact on judicious antibiotic use or colonization with drug-resistant S pneumoniae. Longer follow-up time or greater reductions in antibiotic use may be required to identify changes in the pneumococcal susceptibility.", "To investigate the role of Mycoplasma pneumoniae and Chlamydia pneumoniae infection in pediatric pneumonia, in Istanbul, Turkey, we conducted a prospective study covering all the children between 2 months and 15 years hospitalized for community-acquired pneumonia.\n A total of 140 children (85 males, median age 2.5 years) with community-acquired pneumonia were enrolled. Acute and convalescent sera were tested for IgM and IgG antibodies to M. pneumoniae (enzyme-linked immunosorbent assay, Serion ELISA classic) and for IgM and IgG antibodies to C. pneumoniae (microimmunofluorescence, Savyon, Israel).\n Mycoplasma pneumoniae infection was diagnosed in 38 patients (27%) and C. pneumoniae infection in 7 (5%). In 2 children M. pneumoniae and C. pneumoniae co infection was observed. The average age of the M. pneumoniae cases was 5.3 years and that of the C. pneumoniae was 1.5 years. The average age of pneumonia cases caused by other pathogens was 3.4 years (p<0.05). No significant difference was observed in clinical onset, signs, symptoms and laboratory parameters in children with M. pneumoniae and C. pneumoniae infection and in those without M. pneumoniae and C. pneumoniae infection.\n The results of this study suggest a remarkable role for M. pneumoniae and C. pneumoniae in childhood community-acquired pneumonia, and the knowledge of the true prevalence of these two types of infections discovered in the community might lead to modifications in the present empirical treatment of bacterial pneumonia.", "Pneumonia and malaria, two of the leading causes of morbidity and mortality among children under five in Zambia, often have overlapping clinical manifestations. Zambia is piloting the use of artemether-lumefantrine (AL) by community health workers (CHWs) to treat uncomplicated malaria. Valid concerns about potential overuse of AL could be addressed by the use of malaria rapid diagnostics employed at the community level. Currently, CHWs in Zambia evaluate and treat children with suspected malaria in rural areas, but they refer children with suspected pneumonia to the nearest health facility. This study was designed to assess the effectiveness and feasibility of using CHWs to manage nonsevere pneumonia and uncomplicated malaria with the aid of rapid diagnostic tests (RDTs).\n Community health posts staffed by CHWs were matched and randomly allocated to intervention and control arms. Children between the ages of 6 months and 5 years were managed according to the study protocol, as follows. Intervention CHWs performed RDTs, treated test-positive children with AL, and treated those with nonsevere pneumonia (increased respiratory rate) with amoxicillin. Control CHWs did not perform RDTs, treated all febrile children with AL, and referred those with signs of pneumonia to the health facility, as per Ministry of Health policy. The primary outcomes were the use of AL in children with fever and early and appropriate treatment with antibiotics for nonsevere pneumonia. A total of 3,125 children with fever and/or difficult/fast breathing were managed over a 12-month period. In the intervention arm, 27.5% (265/963) of children with fever received AL compared to 99.1% (2066/2084) of control children (risk ratio 0.23, 95% confidence interval 0.14-0.38). For children classified with nonsevere pneumonia, 68.2% (247/362) in the intervention arm and 13.3% (22/203) in the control arm received early and appropriate treatment (risk ratio 5.32, 95% confidence interval 2.19-8.94). There were two deaths in the intervention and one in the control arm.\n The potential for CHWs to use RDTs, AL, and amoxicillin to manage both malaria and pneumonia at the community level is promising and might reduce overuse of AL, as well as provide early and appropriate treatment to children with nonsevere pneumonia.\n ClinicalTrials.govNCT00513500", "Mycoplasma pneumoniae is increasingly recognized as an important cause of community acquired pneumonia (CAP) in children. We determined the importance of M. pneumoniae as a causative agent in 170 children aged 1 month to 15 years who were hospitalized with CAP over a 6-month period. The diagnosis of M. pneumoniae infection was based on serological evidence obtained by a particle agglutination test (SERODIA-MYCO II). A positive serological diagnosis was made if the acute phase serum titer was more than 1:160 or paired samples taken 2-4 weeks apart showed a four-fold or greater rise in the serum titer. M. pneumoniae was identified as the causative agent in 40 (23.5%) children. Children with M. pneumoniae infection were more likely to be older than 3 years (OR 4.0 95%CI 1.8-9.1, p<0.001), Chinese (OR 4.3 95%CI 2.0-8.9, p<0.001), have a duration of illness longer than 7 days prior to admission (OR 6.0 95%CI 2.7-13.5, p<0.001) and have perihilar interstitial changes on chest X-ray (OR 4.6 95%CI 2.2-9.9, p<0.001). A significant number of hospital admissions for CAP in Malaysian children can be attributed to M. pneumoniae. It is important to identify these children so as to administer the most appropriate antibiotic treatment." ]

[ "Endometrial cancer patients with high grade tumours, deep myometrial invasion or advanced stage disease have a poor prognosis. Randomised studies have demonstrated the prevention of loco-regional relapses with radiotherapy (RT) with no effect on overall survival (OS). The possible additive effect of chemotherapy (CT) remains unclear. Two randomised clinical trials (NSGO-EC-9501/EORTC-55991 and MaNGO ILIADE-III) were undertaken to clarify if sequential combination of chemotherapy and radiotherapy improves progression-free survival (PFS) in high-risk endometrial cancer. The two studies were pooled.\n Patients (n=540; 534 evaluable) with operated endometrial cancer International Federation of Obstetrics and Gynaecology (FIGO) stage I-III with no residual tumour and prognostic factors implying high-risk were randomly allocated to adjuvant radiotherapy with or without sequential chemotherapy.\n In the NSGO/EORTC study, the combined modality treatment was associated with 36% reduction in the risk for relapse or death (hazard ratio (HR) 0.64, 95%confidence interval (CI) 0.41-0.99; P=0.04); two-sided tests were used. The result from the Gynaecologic Oncology group at the Mario Negri Institute (MaNGO)-study pointed in the same direction (HR 0.61), but was not significant. In the combined analysis, the estimate of risk for relapse or death was similar but with narrower confidence limits (HR 0.63, CI 0.44-0.89; P=0.009). Neither study showed significant differences in the overall survival. In the combined analysis, overall survival approached statistical significance (HR 0.69, CI 0.46-1.03; P=0.07) and cancer-specific survival (CSS) was significant (HR 0.55, CI 0.35-0.88; P=0.01).\n Addition of adjuvant chemotherapy to radiation improves progression-free survival in operated endometrial cancer patients with no residual tumour and a high-risk profile. A remaining question for future studies is if addition of radiotherapy to chemotherapy improves the results.\n Copyright 2010 Elsevier Ltd. All rights reserved.", "The question of whether platinum-based adjuvant chemotherapy can improve outcomes in patients with early-stage epithelial ovarian cancer is an important one. We carried out a multicenter, open randomized trial to determine whether adjuvant chemotherapy would improve overall survival and prolong recurrence-free survival in women with early-stage epithelial ovarian cancer.\n Between August 1991 and January 2000, 477 patients in 84 centers in five countries were randomly assigned to receive either adjuvant chemotherapy immediately following surgery (n = 241) or no adjuvant chemotherapy until clinically indicated (n = 236). Kaplan-Meier curves of overall survival and recurrence-free survival were compared using the Mantel-Cox version of the log-rank test. All statistical tests were two-sided.\n Women who received adjuvant chemotherapy had better overall survival than women who did not (hazard ratio [HR] of 0.66, 95% confidence interval [CI] = 0.45 to 0.97; P =.03). These results translate into 5-year survival figures of 70% for women who did not receive adjuvant chemotherapy and 79% for women who did receive adjuvant chemotherapy, a difference of 9% (95% CI = 1% to 15%). Adjuvant chemotherapy also improved recurrence-free survival (HR = 0.65; 95% CI = 0.46 to 0.91; P =.01). These results translate into 5-year recurrence-free survival figures of 62% for women who did not receive adjuvant chemotherapy and 73% for women who did receive adjuvant chemotherapy, a difference of 11% (95% CI = 3% to 18%).\n These results suggest that platinum-based adjuvant chemotherapy improves survival and delays recurrence in patients with early-stage ovarian cancer.", "Patients with high-risk endometrial carcinoma (stage IcG3, IIG3 with myometrial invasion >50%, and III) receive adjuvant therapy after surgery but it is not clear whether radiotherapy (RT) or chemotherapy (CT) is better. We randomly assigned 345 patients with high-risk endometrial carcinoma to adjuvant CT (cisplatin (50 mg m(-2)), doxorubicin (45 mg m(-2)), cyclophosphamide (600 mg m(-2)) every 28 days for five cycles, or external RT (45-50 Gy on a 5 days week(-1) schedule). The primary end points were overall and progression-free survival. After a median follow-up of 95.5 months women in the CT group as compared with the RT group, had a no significant hazard ratio (HR) for death of 0.95 (95% confidence interval (CI), 0.66-1.36; P = 0.77) and a nonsignificant HR for event of 0.88 (95% CI, 0.63-1.23; P = 0.45).

The 3, 5 and 7-year progression-free survivals were, respectively, 69, 63 and 56 and 68, 63 and 60%. Radiotherapy delayed local relapses and CT delayed metastases but these trends did not achieve statistical significance. Overall, both treatments were well tolerated. This trial failed to show any improvement in survival of patients treated with CT or the standard adjuvant radiation therapy. Randomised trials of pelvic RT combined with adjuvant cytotoxic therapy compared with RT alone are eagerly awaited.", "To address whether all medically fit patients with curatively resected stage II colon cancer should be offered adjuvant chemotherapy as part of routine clinical practice, to identify patients with poor prognosis characteristics, and to describe strategies for oncologists to use to discuss adjuvant chemotherapy in practice.\n An American Society of Clinical Oncology Panel, in collaboration with the Cancer Care Ontario Practice Guideline Initiative, reviewed pertinent information from the literature through May 2003.\n A literature-based meta-analysis found no evidence of a statistically significant survival benefit of adjuvant chemotherapy for stage II patients. Recommendations The routine use of adjuvant chemotherapy for medically fit patients with stage II colon cancer is not recommended. However, there are populations of patients with stage II disease that could be considered for adjuvant therapy, including patients with inadequately sampled nodes, T4 lesions, perforation, or poorly differentiated histology.\n Direct evidence from randomized controlled trials does not support the routine use of adjuvant chemotherapy for patients with stage II colon cancer. Patients and oncologists who accept the relative benefit in stage III disease as adequate indirect evidence of benefit for stage II disease are justified in considering the use of adjuvant chemotherapy, particularly for those patients with high-risk stage II disease. The ultimate clinical decision should be based on discussions with the patient about the nature of the evidence supporting treatment, the anticipated morbidity of treatment, the presence of high-risk prognostic features on individual prognosis, and patient preferences. Patients with stage II disease should be encouraged to participate in randomized trials.", "Our purpose was to establish whether platinum-based chemotherapy combined with standard surgery and radiotherapy will improve overall and disease-free survival and lower the recurrence rate in patients with high-risk endometrial cancer.\n A total of 156 patients with Stage IA-B Grade 3 (n=28), or Stage IC-IIIA Grade 1-3 (n=128) were postoperatively randomized to receive radiotherapy (56 Gy) only (Group A, n=72) or radiotherapy combined with three courses of cisplatin (50 mg/m(2)), epirubicin (60 mg/m(2)) and cyclophosphamide (500 mg/m(2)) (Group B, n=84).\n The disease-specific overall five-year survival was in Group A 84.7% vs. 82.1% in Group B (p=0.148). The median disease-free survival in A was 18 (range 9-36) months and 25 (range 12-49) months in B (p=0.134), respectively. During a five-year follow-up 32 patients relapsed. Of the recurrences 5 were local and 20 distant, while 7 were combined. As calculated from the operation, the median time to recurrence was 15 (range 6-37) months in Group A, and 20 (range 8-60) months in Group B, respectively (p=0.170). Twenty-six patients died of the disease during the five-year follow-up, 11 in A and 15 in B.

[ "Although an association between subclinical intrauterine infection and preterm birth is well established, there is conflicting evidence regarding the benefits of antibiotic administration to women in preterm labor with intact membranes. We attempted to determine the effect of ampicillin-amoxicillin and erythromycin treatment on prolongation of pregnancy, the rate of preterm birth, and neonatal morbidity in patients with preterm labor and intact membranes.\n A multicenter, randomized, double-blinded, placebo-controlled trial was designed and implemented by the Maternal-Fetal Medicine Units Network of the National Institute of Child Health and Human Development. Two hundred seventy-seven women with singleton pregnancies and preterm labor with intact membranes (24 to 34 weeks) were randomly allocated to receive either antibiotics or placebos.\n Of the 2373 patients screened for participation in this study in six medical centers, 277 women were enrolled (n = 133 for antibiotics group vs n = 144 for placebo group). In each study group, 60% of patients completed all the study medications. The overall prevalence of microbial invasion of the amniotic cavity was 5.8% (14/239). No significant difference between the antibiotic group and the placebo group was found in maternal outcomes, including duration of randomization-to-delivery interval, frequency of preterm delivery (< 37 weeks), frequency of preterm premature rupture of membranes, clinical chorioamnionitis, endometritis, and number of subsequent admissions for preterm labor. Similarly, no significant difference in neonatal outcomes could be detected between the two groups including respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, sepsis, and admission and duration of newborn intensive special care unit hospitalization.\n The results of this study do not support the routine use of antibiotic administration to women in preterm labor with intact membranes." ]

[ "An imbalance between increased neutrophil elastase and a decreased antiprotease shield has been suggested as a factor contributing to the development of chronic lung disease (CLD). We hypothesized that administration of alpha1-proteinase inhibitor (A1PI), also known as alpha1-antitrypsin, to premature neonates would prevent CLD.\n A randomized, placebo-controlled, prospective study of A1PI supplementation was performed. Neonates <24 hours of age with birth weights 600-1000 g on respiratory support, and 1001-1250 g with respiratory distress syndrome (RDS) were eligible. Intravenous A1PI (60 mg/kg) or placebo was infused on days 0, 4, 7, and 14. Primary outcome was CLD in survivors, defined as the need for supplemental oxygen on day 28.\n A total of 106 patients were recruited. There were no significant differences between groups in birth weight or incidence of RDS. The incidence of CLD in survivors was lower in the treated group, but the difference did not reach statistical significance (relative risk [RR], 0.79; confidence interval [CI], 0.60-1.02). This beneficial trend persisted at 36 weeks corrected gestational age (RR, 0.48; CI, 0.23-1.00). The incidence of pulmonary hemorrhage was lower in the treated group (RR, 0.22; CI, 0.05-0.98). Other complications were not significantly different between groups.\n In this, the first trial of a protease inhibitor for the prevention of CLD in premature infants, the infusions were well-tolerated. A1PI therapy may impede the development of CLD and appears to reduce the incidence of pulmonary hemorrhage in some neonates born prematurely." ]

General inhalational anesthesia with neuromuscular blockade was used. No barbiturates or opioids were given. Infants were randomly divided into two groups. Group 1 received iv caffeine 10 mg/kg immediately after induction of anesthesia. Group 2 received iv saline. Respiratory pattern, heart rate, and SpO2 were monitored using an impedance pneumograph and a pulse oximeter, respectively, for at least 12 h postoperatively. Tracings were analyzed for evidence of apnea, periodic breathing, and/or bradycardia by a pulmonologist unaware of the drug given. None of the patients who received caffeine developed postoperative bradycardia, prolonged apnea, or periodic breathing, and none had postoperative SpO2 less than 90%. In the control group 13 (81%) developed prolonged apnea 4-6 h postoperatively. Fifty percent of the patients had SpO2 less than 90% at the time. This study shows that iv caffeine 10 mg/kg is effective in the control of apnea in otherwise healthy expremature infants between 37 and 44 weeks of postconceptual age. It is still recommended, however, that all infants at risk be monitored for at least 12 h for apnea and bradycardia following general anesthesia.", "nan", "nan" ]

The requirement for mechanical ventilation, complications of treatment, and effects on mid-term outcome were also evaluated.\n Use of the IFD had a significantly beneficial effect on both oxygen requirement and respiratory rate (p < 0.0001) when compared with nCPAP. Moreover, O(2) requirement and respiratory rate were significantly decreased by four hours (p < 0.001 and p < 0.03 respectively). The probability of remaining supplementary oxygen free over the first 48 hours of treatment was significantly higher in patients treated with the IFD than with nCPAP (p < 0.02). IFD treated patients had a higher success (weaning) rate (94% v 72 %) and shorter duration of treatment (49.3 (31) v 56 (29.7) hours respectively; mean (SD)), although the difference was not significant.\n IFD appears to be a feasible device for managing respiratory distress syndrome in preterm infants, and benefits may be had with regard to oxygen requirement and respiratory rate when compared with nCPAP. The trend towards reduced requirement for mechanical ventilation, shorter clinical recovery time, and shorter duration of treatment requires further evaluation in a multicentre randomised clinical trial.", "To determine the comparative efficacy of Exosurf Neonatal and Survanta surfactants on the early course of respiratory distress syndrome (RDS), arterial blood gases, ventilatory support, outcome morbidity rate, and complications of prematurity and RDS.\n Medical records from 203 premature newborn infants undergoing mechanical ventilation for respiratory distress syndrome, and who received up to four rescue doses of either Exosurf or Survanta, were retrospectively reviewed.\n All groups were comparable for birth weight and gestational age. Although the two randomized groups were similar in severity of RDS based on fraction of inspired oxygen (FIO2) and ventilatory support, a significantly greater improvement in respiratory function as evidenced by FIO2, mean airway pressure, alveolar-arterial partial pressure of oxygen difference, and oxygen index, was observed in the Survanta group from 12 hours (p < 0.05) through 48 hours (p < 0.01). Comparison of outcome morbidity rate by gestational age showed a higher occurrence of retinopathy of prematurity (p < 0.02) among the older infants (28 to 32 weeks) who were treated with Exosurf.\n Survanta exerted a significantly faster response in the early clinical course of RDS compared with Exosurf. However, no difference in the impact on eventual respiratory outcome was observed. We therefore conclude that both surfactants are effective for the treatment of RDS.", "OBJECTIVE: Few studies have compared the performance of nasal prongs used for applying continuous positive airway pressure. The present study compared the tolerance and efficacy with the Argyle and Hudson nasal prongs. DESIGN: A prospective, randomized clinical study. SETTING: A tertiary neonatal intensive care unit in a university hospital. PATIENTS: A total of 99 preterm infants weighing </=2500 g were assigned to one of three weight categories. They were then randomly assigned to use one of two nasal prong types. The number of times the prongs were out of the nostrils, time on nasal continuous positive airway pressure, respiratory and heart rate, Silverman-Andersen retraction score, blood gases, abdominal distention, nasal hyperemia and bleeding, septum necrosis, pneumothorax, and therapeutic success were documented. MEASUREMENTS AND MAIN RESULTS: The two groups were matched for weight, gestational age, and disease for which the continuous positive airway pressure was used. For patients weighing 1500-2000 g, the Hudson users had a greater gestational age. Both types of nasal prongs reduced the Silverman-Andersen retraction score in all infants 2 hrs after continuous positive airway pressure application, except for patients weighing </=1000 g. The Argyle prong was related to a higher frequency of hyperemia in babies weighing <1500 g (p =.03). There were no cases of septum necrosis or pneumothorax. The frequency of therapeutic success for patients using Hudson prongs and weighing >/=1500 g was significantly higher than for those using the Argyle catheter (p =.03). CONCLUSION: Considering the difference in gestational age for the patients weighing 1500-2500 g, we conclude that the two prongs tested are equally effective for nasal continuous positive airway pressure, but the Argyle prong is more difficult to keep in the nostrils of active patients, and nasal hyperemia, the first sign of tissue aggression, occurs more frequently among infants using this prong.", "To determine whether synchronized nasal intermittent positive pressure ventilation (SNIPPV) would decrease extubation failure compared with nasal continuous positive airway pressure (NCPAP) in preterm infants being ventilated for respiratory distress syndrome (RDS).\n Infants who were </=34 weeks' gestational age and who were ventilated for RDS were randomized to either SNIPPV or NCPAP after extubation. The criteria for extubation were peak inspiratory pressure of </=16 cm H(2)O, positive end expiratory pressure of </=5 cm H(2)O, intermittent mandatory ventilation rate of 15 to 25, and fraction of inspired oxygen </=0.35. Pulmonary function tests (PFT) were obtained before extubation. After extubation, blood gases were monitored for a minimum of 72 hours. Success was defined as remaining in the selected mode of treatment or demonstrating improvement (switching to oxyhood/nasal cannula/room air) by 72 hours.\n Thirty-two (94%) of 34 infants were extubated successfully with the use of SNIPPV versus 18 (60%) of 30 with the use of NCPAP (P <.01). There was no difference in apnea/bradycardia episodes in the 2 groups during the 72-hour study period. Among 55 infants who had PFT, 80% (8 of 10) with dynamic lung compliance of >/=0.5 mL/kg/cm H(2)O and expiratory airway resistance of </=70 cm H(2)O/L/s were extubated successfully. In infants with poor lung function (dynamic lung compliance: <0.5 mL/kg/cm H(2)O; expiratory airway resistance: >70 cm H(2)O/L/s), successful extubation was seen in 93% (27 of 29) in the SNIPPV group and 60% (15 of 25) in the NCPAP group. When weight was controlled for at the time of extubation, the odds of success in the SNIPPV group were 21.1 times higher (95% confidence interval: 3.4, 130.1) than that of the NCPAP group.\n SNIPPV is more effective than NCPAP in weaning infants with RDS from the ventilator. PFT may be useful in predicting successful extubation." ]

The skills training approach was culturally adapted mainly by including the active participation of key relatives to facilitate acquisition and generalization of disease management skills into the patients' natural environment. There was a significant advantage for the ST group over the CC group on several symptom measures, skill acquisition and generalization, level of functioning, and rates of rehospitalization. There were no significant differences between the groups on quality of life or caregiver burden. Skills training had a direct effect on skill acquisition and generalization, and utilization of disease management skills led to decreased rates of rehospitalization.

RAP-Kiwi was an 11-session manual-based program derived from cognitive-behavioral therapy. The placebo was similar but with cognitive components removed. Outcomes were self-rated depression scales, the Reynolds Adolescent Depression Scale (RADS), and the Beck Depression Inventory II (BDI-II). Follow-up was to 18 months. Analysis was done on an intent-to-treat basis.\n Immediately after the intervention, depression scores were reduced significantly more by RAP-Kiwi than by placebo, with a mean difference in change from baseline between groups of 1.5 on BDI-II (CI > 0.38, p =.01) and 2.24 on RADS (CI > 0.22, p =.04). Categorical analysis confirmed significant clinical benefit with an absolute risk reduction of 3% (95% CI, 1-11%, McNemar chi, p =.03), with the \"number needed to treat\" for short-term benefit of 33. Group differences in depression scores averaged across time to 18 months were significant on RADS but not on BDI-II. Retention rates were 91% at 6 months and 72% at 18 months.\n The RAP-Kiwi program is a potentially effective public health measure. Confirmation of effectiveness measuring episodes of depressive illness and broader measures of adjustment is warranted.", "Depressive disorders are experienced by 3-5% of the adolescent population at any point of time. They adversely affect adolescent development in a range of areas and greatly increase risk for suicide. The present study investigated the effectiveness of a universal intervention designed to reduce depressive symptoms among students commencing high school.\n Twenty-five pairs of secondary schools matched on socio-economic status were randomly assigned to either an intervention or a comparison group (n = 5,634 Year 8 students). The intervention extended over a 3-year period and utilised a comprehensive classroom curriculum programme, enhancements to the school climate, improvements in care pathways, and community forums. A range of measures completed by students, average age at baseline = 13.1 years (SD = .5), and teachers was used to assess changes in depressive symptoms, risk and protective factors relevant to depression, and the quality of the school environment.\n Changes in the level of depressive symptoms and in the levels of risk and protective factors experienced by students in the two groups did not differ significantly over the 3 years of the study. Furthermore, statistically significant differences in the ratings of school climate across this time period were found only for staff-rated assessments.\n Despite using an extensive, structured programme, based on best evidence to increase protective factors and reduce risk factors at the individual and school levels, the intervention did not reduce levels of depressive symptoms among participating adolescents. The results draw attention to the difficulties faced when implementing large-scale, school-based, universal preventive interventions. These include the need to develop methods to effectively train teachers across large geographical regions to deliver new interventions with fidelity, the difficulty of engaging young adolescents with prevention programmes, and the long period of time required to implement policy and practice changes at 'whole-school' levels.", "This study evaluated the efficacy of 2 programs for preventing depressive symptoms in adolescents. Participants were 380 high school students randomly assigned to a cognitive-behavioral program (CB), an interpersonal psychotherapy-adolescent skills training program (IPT-AST), or a no-intervention control. The interventions involved eight 90-min weekly sessions run in small groups during wellness classes. At postintervention, students in both the CB and IPT-AST groups reported significantly lower levels of depressive symptoms than did those in the no-intervention group, controlling for baseline depression scores; the 2 intervention groups did not differ significantly from each other. The effect sizes, using Cohen's d, for the CB intervention and the IPT-AST intervention were 0.37 and 0.26, respectively. Differences between control and intervention groups were largest for adolescents with high levels of depressive symptoms at baseline. For a high-risk subgroup, defined as having scored in the top 25th percentile on the baseline depression measure, the effect sizes for the CB and the IPT-AST interventions were 0.89 and 0.84, respectively. For the whole sample, sociotropy and achievement orientation moderated the effect of the interventions. Intervention effects were short term and were not maintained at 6-month follow-up.\n (PsycINFO Database Record (c) 2007 APA, all rights reserved).", "The aim in the current study was to investigate the effectiveness of an online, self-directed cognitive-behavioral therapy program (MoodGYM) in preventing and reducing the symptoms of anxiety and depression in an adolescent school-based population. A cluster randomized controlled trial was conducted with 30 schools (N = 1,477) from across Australia, with each school randomly allocated to the intervention or wait-list control condition. At postintervention and 6-month follow-up, participants in the intervention condition had significantly lower levels of anxiety than did participants in the wait-list control condition (Cohen's d = 0.15-0.25). The effects of the MoodGYM program on depressive symptoms were less strong, with only male participants in the intervention condition exhibiting significant reductions in depressive symptoms at postintervention and 6-month follow-up (Cohen's d = 0.27-0.43). Although small to moderate, the effects obtained in the current study provide support for the utility of universal prevention programs in schools. The effectiveness of booster sessions should be explored in future research.", "A randomized controlled trial was conducted to evaluate the efficacy of a cognitive-behavioral (CBT) intervention to prevent perinatal depression in high-risk Latinas.\n A sample of 217 participants, predominantly low-income Central American immigrants who met demographic and depression risk criteria, were randomized into usual care (UC; n = 105) or an 8-week CBT group intervention during pregnancy and 3 individual booster sessions during postpartum (n = 112). Participants completed measures assessing depressive symptoms (Center for Epidemiological Studies Depression Scale at baseline; Beck Depression Inventory, Second Edition [BDI-II]) and major depressive episodes (Mood Screener) at 5 time points throughout the perinatal period.\n Intent-to-treat analyses indicated that intervention participants had significantly lower depressive symptoms and fewer cases of moderate depression (BDI-II ≥ 20) at Time 2 than UC participants. These effects were stronger for women who fully participated in the intervention (≥ 4 classes). The cumulative incidence of major depressive episodes was not significantly different between the intervention (7.8%) and UC (9.6%) groups.\n A CBT intervention for low-income, high-risk Latinas reduced depressive symptoms during pregnancy but not during the postpartum period. Low levels of depressive symptoms and lower than expected rates of clinical depression in both groups may partially be due to methodological issues. As perinatal depression is a significant public health problem, more work is needed to prevent perinatal depression in low-income, ethnically diverse women.\n (c) 2011 APA, all rights reserved.", "A controlled trial was conducted to evaluate a prevention program aimed at reducing depressive and anxious symptoms in rural school children. Seventh-grade children with elevated depression were selected. Nine primary schools (n = 90) were randomly assigned to receive the program, and 9 control schools (n = 99) received their usual health education classes. Children completed questionnaires on depression, anxiety, explanatory style, and social skills. Parents completed the Child Behavior Checklist (T. M. Achenbach, 1991). No intervention effects were found for depression. Intervention group children reported less anxiety than the control group after the program and at 6-month follow-up and more optimistic explanations at postintervention.

Late-life depression is associated with chronic illness and disability.\n To investigate the feasibility of a collaborative care model for depression in older people in a primary care setting.\n Randomised controlled trial with 16-weeks follow up.\n A primary care trust in Manchester.\n Participants were 105 people aged 60 years or older who scored 5 or more on the Geriatric Depression Scale; 53 were randomly allocated to an intervention group and 52 to a usual care group. The intervention group received care managed by a community psychiatric nurse who delivered an intervention comprising a facilitated self-help programme with close liaison with primary care professionals and old-age psychiatry according to a defined protocol. The usual care group received usual GP care. A nested qualitative study explored the views of the health professionals and patients regarding the acceptability and effectiveness of the intervention.\n The main outcome measure was recovery from depression. Patients in the intervention group were less likely to suffer from major depressive disorder at follow up compared with usual care (0.32, 95% confidence = interval = 0.11 to 0.93, P = 0.036). The qualitative component of the study demonstrated the acceptability of the intervention to patients.\n A model of collaborative care for older people with depression, used in a primary care setting with a facilitated self-help intervention is more effective than usual GP care. This study demonstrates that the implementation of a collaborative care model is feasible in UK primary care and that the intervention is effective and acceptable to patients.", "In this depression prevention trial, 341 high-risk adolescents (mean age = 15.6 years, SD = 1.2) with elevated depressive symptoms were randomized to a brief group cognitive-behavioral (CB) intervention, group supportive-expressive intervention, bibliotherapy, or assessment-only control condition. CB participants showed significantly greater reductions in depressive symptoms than did supportive-expressive, bibliotherapy, and assessment-only participants at posttest, though only the difference compared with assessment controls was significant at 6-month follow-up. CB participants showed significantly greater improvements in social adjustment and reductions in substance use at posttest and 6-month follow-up than did participants in all 3 other conditions. Supportive-expressive and bibliotherapy participants showed greater reductions in depressive symptoms than did assessment-only controls at certain follow-up assessments but produced no effects for social adjustment and substance use. CB, supportive-expressive, and bibliotherapy participants showed a significantly lower risk for major depression onset over the 6-month follow-up than did assessment-only controls. The evidence that this brief CB intervention reduced risk for future depression onset and outperformed alternative interventions for certain ecologically important outcomes suggests that this intervention may have clinical utility.\n Copyright 2008 APA, all rights reserved.", "Adolescent offspring of depressed parents are at markedly increased risk of developing depressive disorders. Although some smaller targeted prevention trials have found that depression risk can be reduced, these results have yet to be replicated and extended to large-scale, at-risk populations in different settings.\n To determine the effects of a group cognitive behavioral (CB) prevention program compared with usual care in preventing the onset of depression.\n A multicenter randomized controlled trial conducted in 4 US cities in which 316 adolescent (aged 13-17 years) offspring of parents with current or prior depressive disorders were recruited from August 2003 through February 2006. Adolescents had a past history of depression, current elevated but subdiagnostic depressive symptoms, or both. Assessments were conducted at baseline, after the 8-week intervention, and after the 6-month continuation phase.\n Adolescents were randomly assigned to the CB prevention program consisting of 8 weekly, 90-minute group sessions followed by 6 monthly continuation sessions or assigned to receive usual care alone.\n Rate and hazard ratio (HR) of a probable or definite depressive episode (ie, depressive symptom rating score of > or = 4) for at least 2 weeks as diagnosed by clinical interviewers.\n Through the postcontinuation session follow-up, the rate and HR of incident depressive episodes were lower for those in the CB prevention program than for those in usual care (21.4% vs 32.7%; HR, 0.63; 95% confidence interval [CI], 0.40-0.98). Adolescents in the CB prevention program also showed significantly greater improvement in self-reported depressive symptoms than those in usual care (coefficient, -1.1; z = -2.2; P = .03). Current parental depression at baseline moderated intervention effects (HR, 5.98; 95% CI, 2.29-15.58; P = .001). Among adolescents whose parents were not depressed at baseline, the CB prevention program was more effective in preventing onset of depression than usual care (11.7% vs 40.5%; HR, 0.24; 95% CI, 0.11-0.50), whereas for adolescents with a currently depressed parent, the CB prevention program was not more effective than usual care in preventing incident depression (31.2% vs 24.3%; HR, 1.43; 95% CI, 0.76-2.67).\n The CB prevention program had a significant prevention effect through the 9-month follow-up period based on both clinical diagnoses and self-reported depressive symptoms, but this effect was not evident for adolescents with a currently depressed parent.\n clinicaltrials.gov Identifier: NCT00073671.", "General practitioners (GPs) can be provided with effective training in the skills to manage depression. However, it remains uncertain whether such training achieves health gain for their patients.\n The study aimed to measure the health gain from training GPs in skills for the assessment and management of depression. The study design was a cluster randomized controlled trial. GP participants were assessed for recognition of psychological disorders, attitudes to depression, prescribing patterns and experience of psychiatry and communication skills training. They were then randomized to receive training at baseline or the end of the study. Patients selected by GPs were assessed at baseline, 3 and 12 months. The primary outcome was depression status, measured by HAM-D. Secondary outcomes were psychiatric symptoms (GHQ-12) quality of life (SF-36), satisfaction with consultations, and health service use and costs.\n Thirty-eight GPs were recruited and 36 (95%) completed the study. They selected 318 patients, of whom 189 (59%) were successfully recruited. At 3 months there were no significant differences between intervention and control patients on HAM-D, GHQ-12 or SF-36. At 12 months there was a positive training effect in two domains of the SF-36, but no differences in HAM-D, GHQ-12 or health care costs. Patients reported trained GPs as somewhat better at listening and understanding but not in the other aspects of satisfaction.\n Although training programmes may improve GPs' skills in managing depression, this does not appear to translate into health gain for depressed patients or the health service.", "Many patients with major depression are non-adherent to antidepressant medication and do not receive care according to current guidelines. There is increasing evidence that treatment of depression in primary care can be improved. Comparison between effective interventions may help to establish the active ingredients of such interventions.\n In a randomized trial two interventions to improve treatment of major depression in primary care were compared (1) a depression care programme, targeting general practitioners (GPs), patients, and systematic follow-up, and (2) a systematic follow-up programme. Thirty GPs were randomized and 211 primary-care patients with current major depression were included. All patients were prescribed a selective serotonin reuptake inhibitor. Outcome measures included adherence to antidepressant medication, and depression outcome.\n No significant differences in adherence rates and treatment outcome measures were demonstrated between interventions at week 10 or week 26. Adherence rates were high and treatment outcome was favourable.\n The depression care programme was not superior to the systematic follow-up programme. Systematic follow-up in depression treatment in primary care seems to be an intervention per se, having the potential to improve adherence and treatment outcome.", "Major depression is a frequent and serious disorder in older medical inpatients. Because the condition goes undetected and untreated in most of these patients, we conducted a randomized clinical trial to evaluate the effectiveness of a strategy of systematic detection and multidisciplinary treatment of depression in this population.\n Consecutive patients aged 65 years or more admitted to general medical services in a primary care hospital between October 1999 and November 2002 were screened for depression with the Diagnostic Interview Schedule (DIS) within 48 hours after admission. Patients found to have major depression were randomly allocated to receive the intervention or usual care. The intervention involved consultation and treatment by a psychiatrist and follow-up by a research nurse and the patient's family physician. Research assistants, blind to group allocation, collected data from the patients at enrollment and at 3 and 6 months later using the Hamilton Depression Rating Scale (HAMD), the Medical Outcomes 36-item Short Form (SF-36), the DIS, the Mini-Mental State Examination (MMSE), the Older Americans Resources and Services (OARS) questionnaire to assess basic and instrumental activities of daily living (OARS-ADL and OARS-IADL) and the Rating Scale for Side Effects. Data on the severity of illness, length of hospital stay, health services and medication use, mortality and process of care were also collected. The primary outcome measures were the HAMD and SF-36.\n Of 1500 eligible patients who were screened, 157 were found to have major depression and consented to participate (78 in the intervention group and 79 in the usual care group). At randomization, there were no clinically or statistically significant differences between the 2 groups. Sixty-four patients completed follow-up to 6 months, 57 withdrew, and 36 died. At 6 months, there were no clinically or statistically significant differences the 2 groups in HAMD or SF-36 scores or any of the secondary outcome measures.\n We were unable to demonstrate that systematic detection and multidisciplinary care of depression was more beneficial than usual care for elderly medical inpatients.", "Depression and anxiety disorders are common mental disorders worldwide. The MANAS trial aimed to test the effectiveness of an intervention led by lay health counsellors in primary care settings to improve outcomes of people with these disorders.\n In this cluster randomised trial, primary care facilities in Goa, India, were assigned (1:1) by computer-generated randomised sequence to intervention or control (enhanced usual care) groups. All adults who screened positive for common mental disorders were eligible. The collaborative stepped-care intervention offered case management and psychosocial interventions, provided by a trained lay health counsellor, supplemented by antidepressant drugs by the primary care physician and supervision by a mental health specialist. The research assessor was masked. The primary outcome was recovery from common mental disorders as defined by the International Statistical Classification of Diseases and Related Health Problems-10th revision (ICD-10) at 6 months. This study is registered with ClinicalTrials.gov, number NCT00446407.\n 24 study clusters, with an equal proportion of public and private facilities, were randomised equally between groups. 1160 of 1360 (85%) patients in the intervention group and 1269 of 1436 (88%) in the control group completed the outcome assessment. Patients with ICD-10-confirmed common mental disorders in the intervention group were more likely to have recovered at 6 months than were those in the control group (n=620 [65·0%] vs 553 [52·9%]; risk ratio 1·22, 95% CI 1·00-1·47; risk difference=12·1%, 95% CI 1·6%-22·5%).

Outcomes were assessed at postintervention (2 months), after completion of 4 monthly booster sessions (6 months), and at 12-month follow-up. Children were assessed by child reports on depressive symptoms, internalizing problems, and externalizing problems; by parent reports on internalizing and externalizing problems; and by child and parent reports on a standardized diagnostic interview. Parent depressive symptoms and parent episodes of major depression also were assessed. Evidence emerged for significant differences favoring the family group intervention on both child and parent outcomes; strongest effects for child outcomes were found at the 12-month assessment with medium effect sizes on most measures. Implications for the prevention of adverse outcomes in children of depressed parents are highlighted.", "This research study evaluates the effectiveness of a multifaceted intervention program to improve the management of depression in primary care.\n One hundred fifty-three primary care patients with current depression were entered into a randomized controlled trial. Intervention patients received a structured depression treatment program in the primary care setting that included both behavioral treatment to increase use of adaptive coping strategies and counseling to improve medication adherence. Control patients received \"usual\" care by their primary care physicians. Outcome measures included adherence to antidepressant medication, satisfaction with care of depression and with antidepressant treatment, and reduction of depressive symptoms over time.\n At 4-month follow-up, significantly more intervention patients with major and minor depression than usual care patients adhered to antidepressant medication and rated the quality of care they received for depression as good to excellent. Intervention patients with major depression demonstrated a significantly greater decrease in depression severity over time compared with usual care patients on all 4 outcome analyses. Intervention patients with minor depression were found to have a significant decrease over time in depression severity on only 1 of 4 study outcome analyses compared with usual care patients.\n A multifaceted primary care intervention improved adherence to antidepressant regimens and satisfaction with care in patients with major and minor depression. The intervention consistently resulted in more favorable depression outcomes among patients with major depression, while outcome effects were ambiguous among patients with minor depression.", "Major depression and dysthymia are frequent, debilitating, and chronic disorders, whose highest rate of initial onset is during the late adolescent years. The effectiveness of a program designed to prevent an initial episode of major depression or dysthymia among adolescents was investigated. Participants were 171 fourteen-year-old \"at risk\" Icelandic adolescents who were randomly assigned to a prevention program or a treatment-as-usual assessment only control group. They were identified as \"at risk\" by reporting the presence of depressive symptoms or a negative attributional style. The program was based on a developmental psychosocial model of enhancement of resilience to factors associated with the occurrence of mood disorders. The results indicated that the prevention program resulted in a significantly lower rate of major depression and dysthymia than did the control group. The study demonstrated that school personnel in the school setting can implement such prevention programs.", "Depression, a common disorder often treated by family physicians, may be both underdiagnosed and undertreated. The objective of this study was to determine whether the diagnosis and treatment of depression by family physicians could be improved through an educational strategy.\n In this study, conducted between July and December 1997, 42 family physicians in Newfoundland were randomly assigned to an intervention group (3-hour case-based educational session on clinical practice guidelines [CPGs] for depression and access to a psychiatrist for consultation) or to a control group (receipt of CPGs without educational session or access to the psychiatrist). Physicians were asked to keep a log of patients with newly diagnosed depression and to record information on severity of depression, medications and referrals to mental health professionals. Patients were asked to complete the Centre for Epidemiologic Studies Depression (CES-D) scale before treatment and after 6 months of follow-up. The primary outcome measure was the \"gain\" score (difference between first and last CES-D scores).\n During the study period physicians in the intervention group diagnosed 91 new cases of depression (mean 4.1 per physician) and those in the control group diagnosed 56 (mean 2.8 per physician); the difference was not significant. Most patients (91.2% in the intervention group and 89.3% in the control group received a prescription for an antidepressant on their first visit. Similar proportions (46.2% in the intervention group and 37.5% in the control group) took their medication for the full 6 months; however, significantly more patients in the intervention group were taking an antidepressant at the 6-month follow-up (56% v. 39.3%, p = 0.02). The mean number of visits per patient was similar in the 2 groups (7.7 in the intervention group and 7.6 in the control group). Physicians in the intervention group consulted the psychiatrist 9 times. The overall rate of referrals to psychiatrists and other mental health professionals was 10.9%; however, referrals were significantly higher in the intervention group (15.4% v. 3.5%, p = 0.05). After 6 months of follow-up, a significant difference in gain scores was detected between the intervention and control groups for both the patient's self-rated CES-D scores (mean gain score 19.3 v. 15.5 respectively, p = 0.04) and the physicians' ratings of depression severity before treatment and at 6 months (mean gain 1.1 v. 0.7 respectively, p = 0.02).\n The educational strategy had a modest beneficial effect on the outcomes of patients with depression, but there are still concerns regarding the low rates of drug treatment and referral to mental health professionals by family physicians.", "Various methods are available for implementing change in the clinical behaviour of general practitioners (GPs). Although passive dissemination of information is generally ineffective, other methods can be variably effective.

The main outcome measures were: record of adherence to guideline recommendations in clinical records; proportion of patients with Beck Depression Inventory (BDI) score less than 11 at 16 weeks after diagnosis.\n In comparison with the control group, in the group of GPs receiving tailored implementation, there were increases in the proportions of patients assessed for suicide risk. In the intervention group, the proportion of patients with BDI scores of less than 11 at 16 weeks increased.\n Obstacles to implementation can be identified and strategies tailored to address them. The findings indicate a new approach for research to understand and develop methods of implementation.", "Social support theory and observational risk factor studies suggest that increased antenatal psychosocial support could prevent post-natal depression. We used empirical knowledge of risk and protective factors for post-natal depression not employed previously in order to develop and evaluate an antenatal preventive intervention.\n We conducted a pragmatic randomized controlled trial in antenatal clinics. We screened 1300 primiparous women and 400 screened positive, 69 screen-positive women were untraceable or not eligible. Of 292 women who completed baseline assessment, 209 consented to randomization, of these 190 provided outcome data 3 months post-natally. 'Preparing for Parenthood', a structured antenatal risk factor reducing intervention designed to increase social support and problem-solving skills, was compared with routine antenatal care only. We compared the percentage depressed at 3 months after childbirth using the self-completion General Health Questionnaire Depression scale and Edinburgh Post-natal Depression Scale (EPDS), and the Schedules for Clinical Assessment in Neuropsychiatry a systematic clinical interview.\n Assignment to the intervention group did not significantly impact on post-natal depression (odds ratio for GHQ-Depression 1.22 (95% CI 0.63-2.39), P = 0.55) or on risk factors for depression. Forty-five per cent of the intervention group women attended sufficient sessions to be likely to benefit from intervention if effective. Attenders benefited no more than non-attenders.\n Prevention services targeting post-natal depression should not implement antenatal support programmes on these lines until further research has demonstrated the feasibility and effectiveness of such methods. The development of novel, low cost interventions effective in reducing risk factors should be completed before further trial evaluation.", "Despite high rates of relapse and recurrence, few primary care patients with recurrent or chronic depression are receiving continuation and maintenance-phase treatment. We hypothesized that a relapse prevention intervention would improve adherence to antidepressant medication and improve depression outcomes in high-risk patients compared with usual primary care.\n Three hundred eighty-six patients with recurrent major depression or dysthymia who had largely recovered after 8 weeks of antidepressant treatment by their primary care physicians were randomized to a relapse prevention program (n = 194) or usual primary care (n = 192). Patients in the intervention group received 2 primary care visits with a depression specialist and 3 telephone visits over a 1-year period aimed at enhancing adherence to antidepressant medication, recognition of prodromal symptoms, monitoring of symptoms, and development of a written relapse prevention plan. Follow-up assessments were completed at 3, 6, 9, and 12 months by a telephone survey team blinded to randomization status.\n Those in the intervention group had significantly greater adherence to adequate dosage of antidepressant medication for 90 days or more within the first and second 6-month periods and were significantly more likely to refill medication prescriptions during the 12-month follow-up compared with usual care controls. Intervention patients had significantly fewer depressive symptoms, but not fewer episodes of relapse/recurrence over the 12-month follow-up period.\n A relapse prevention program targeted to primary care patients with a high risk of relapse/recurrence who had largely recovered after antidepressant treatment significantly improved antidepressant adherence and depressive symptom outcomes.", "The majority of randomised controlled trials examining the effectiveness of antenatal group interventions at preventing postnatal depression in \"at risk\" women have used a \"psychoeducational\" intervention. The aim of the present study is to evaluate the effectiveness of an antenatal cognitive behavioural group intervention in a primary care setting for pregnant women identified with mild to moderate symptoms in pregnancy and/or at risk of developing depression or anxiety in the perinatal period.\n Subjects were randomised to a CBT group intervention or control condition (information booklet) and administered the EPDS and STAI at pre (Time 1) and post intervention (Time 2), and at 2 months (Time 3) and 4 months postpartum (Time 4). MINIs were administered at Times 1, 3 and 4.\n Of the 774 women approached, 277 accepted and were suitable; thus 191 were randomised to the CBT intervention and 86 to the control condition. The subsequent 52% drop-out left 89 women \"completing\" the CBT groups and 43 in the control group; these two groups were well matched on demographic variables. Intention to treat analyses revealed relatively low mean baseline EPDS scores (means 6.88 -8.16) with no reduction in EPDS scores in either group from Time 1 to Time 4. MINI depression criteria were fulfilled by 19% of all participants at Time 1 but there was no reduction in depression in either group; in contrast those with MINI anxiety diagnoses reduced from 28% in late pregnancy to 16% at four months postpartum in the CBT group with similar reductions in the control group. Analyses on the 132 \"completers\" showed significant symptomatic improvement over time for both the CBT group and control condition. Depression scores in the most symptomatic women (EPDS>12; N=19) decreased steadily by over 50% over the total time course but there were no differences in improvement between the CBT and control groups.\n A number of methodological factors may have obscured our results including a tendency to natural remission in mildly symptomatic subjects and the possibility that our control condition was therapeutic in itself.\n While a modest reduction in depression scores was noted in study \"completers\", both the CBT group intervention control condition were equally beneficial. The reasons for this finding include the low symptom level at baseline; the potential effectiveness of the control condition; and the brevity of the intervention.", "To compare the effectiveness of a multifaceted intervention in patients with depression in primary care with the effectiveness of \"usual care\" by the primary care physician.\n A randomized controlled trial among primary care patients with major depression or minor depression.\n Over a 12-month period a total of 217 primary care patients who were recognized as depressed by their primary care physicians and were willing to take antidepressant medication were randomized, with 91 patients meeting criteria for major depression and 126 for minor depression.\n Intervention patients received increased intensity and frequency of visits over the first 4 to 6 weeks of treatment (visits 1 and 3 with a primary care physician, visits 2 and 4 with a psychiatrist) and continued surveillance of adherence to medication regimens during the continuation and maintenance phases of treatment. Patient education in these visits was supplemented by videotaped and written materials.\n Primary outcome measures included short-term (30-day) and long-term (90-day) use of antidepressant medication at guideline dosage levels, satisfaction with overall care for depression and antidepressant medication, and reduction in depressive symptoms.\n In patients with major depression, the intervention group had greater adherence than the usual care controls to adequate dosage of antidepressant medication for 90 days or more (75.5% vs 50.0%; P < .01), were more likely to rate the quality of the care they received for depression as good to excellent (93.0% vs 75.0%; P < .03), and were more likely to rate antidepressant medications as helping somewhat to helping a great deal (88.1% vs 63.3%; P < .01). Seventy-four percent of intervention patients with major depression showed 50% or more improvement on the Symptom Checklist-90 Depressive Symptom Scale compared with 43.8% of controls (P < .01), and the intervention patients also demonstrated a significantly greater decrease in depression severity over time compared with controls (P < .004). In patients with minor depression, the intervention group had significantly greater adherence than controls to adequate dosage of antidepressant medication for 90 days or more (79.7% vs 40.3%; P < .001) and more often rated antidepressant medication as helping somewhat to helping a great deal (81.8% vs 61.4%; P < .02). However, no significant differences were found between the intervention and control groups in the percentage of patients who were satisfied with the care they received for depression (94.4% vs 89.3%), in the percentage who experienced a 50% or more decrease in depressive symptoms, or in the decrease of depressive symptoms over time.\n A multifaceted intervention consisting of collaborative management by the primary care physician and a consulting psychiatrist, intensive patient education, and surveillance of continued refills of antidepressant medication improved adherence to antidepressant regimens in patients with major and with minor depression. It improved satisfaction with care and resulted in more favorable depressive outcomes in patients with major, but not minor, depression.", "The authors investigated the effectiveness and specificity of the Penn Resiliency Program (PRP; J. E. Gillham, L. H. Jaycox, K. J. Reivich, M. E. P. Seligman, & T. Silver, 1990), a cognitive-behavioral depression prevention program. Children (N = 697) from 3 middle schools were randomly assigned to PRP, Control (CON), or the Penn Enhancement Program (PEP; K. J. Reivich, 1996; A. J. Shatté, 1997), an alternate intervention that controls for nonspecific intervention ingredients. Children's depressive symptoms were assessed through 3 years of follow-up. There was no intervention effect on average levels of depressive symptoms in the full sample. Findings varied by school. In 2 schools, PRP significantly reduced depressive symptoms across the follow-up relative to both CON and PEP. In the 3rd school, PRP did not prevent depressive symptoms. The authors discuss the findings in relation to previous research on PRP and the dissemination of prevention programs.\n Copyright 2007 APA, all rights reserved.", "Those who were labelled as depressives in a rural survey were randomly divided into a Medicine group (who received antidepressive drug treatment), a Placebo group (who received placebo) and a Natural Process group (who received no treatment). The depth of their depression was assessed by Hamilton's Depressive Rating Scale before the beginning of the trial, on the 14th day and on the 28th day of trial. They were compared with a matched group of healthy controls and again with a matched group of depressives who attended an urban clinic for treatment. The results indicate that the rural depressives who never sought treatment voluntarily were not different from those who sought treatment in clinics, so far as their response to treatment is concerned.", "The aim of this study was to determine both the clinical and cost-effectiveness of usual general practitioner (GP) care compared with two types of brief psychological therapy (non-directive counselling and cognitive-behaviour therapy) in the management of depression as well as mixed anxiety and depression in the primary care setting.\n The design was principally a pragmatic randomised controlled trial, but was accompanied by two additional allocation methods allowing patient preference: the option of a specific choice of treatment (preference allocation) and the option to be randomised between the psychological therapies only. Of the 464 patients allocated to the three treatments, 197 were randomised between the three treatments, 137 chose a specific treatment, and 130 were randomised between the psychological therapies only. The patients underwent follow-up assessments at 4 and 12 months.\n The study was conducted in 24 general practices in Greater Manchester and London.\n A total of 464 eligible patients, aged 18 years and over, were referred by 73 GPs and allocated to one of the psychological therapies or usual GP care for depressive symptoms.\n The interventions consisted of brief psychological therapy (12 sessions maximum) or usual GP care. Non-directive counselling was provided by counsellors who were qualified for accreditation by the British Association for Counselling. Cognitive-behaviour therapy was provided by clinical psychologists who were qualified for accreditation by the British Association for Behavioural and Cognitive Psychotherapies. Usual GP care included discussions with patients and the prescription of medication, but GPs were asked to refrain from referring patients for psychological intervention for at least 4 months. Most therapy sessions took place on a weekly basis in the general practices. By the 12-month follow-up, GP care in some cases did include referral to mental healthcare specialists.\n The clinical outcomes included depressive symptoms, general psychiatric symptoms, social function and patient satisfaction. The economic outcomes included direct and indirect costs and quality of life. Assessments were carried out at baseline during face-to-face interviews as well as at 4 and 12 months in person or by post.\n At 4 months, both psychological therapies had reduced depressive symptoms to a significantly greater extent than usual GP care. Patients in the psychological therapy groups exhibited mean scores on the Beck Depression Inventory that were 4-5 points lower than the mean score of patients in the usual GP care group, a difference that was also clinically significant. These differences did not generalize to other measures of outcome. There was no significant difference in outcome between the two psychological therapies when they were compared directly using all 260 patients randomised to a psychological therapy by either randomised allocation method. At 12 months, the patients in all three groups had improved to the same extent. The lack of a significant difference between the treatment groups at this point resulted from greater improvement of the patients in the GP care group between the 4- and 12-month follow-ups. At 4 months, patients in both psychological therapy groups were more satisfied with their treatment than those in the usual GP care group. However, by 12 months, patients who had received non-directive counselling were more satisfied than those in either of the other two groups. There were few differences in the baseline characteristics of patients who were randomised or expressed a treatment preference, and no differences in outcome between these patients. Similar outcomes were found for patients who chose either psychological therapy. Again, there were no significant differences between the two groups at 4 or 12 months. Patients who chose counselling were more satisfied with treatment than those who chose c", "Major depressive disorder severely impairs the quality of life of patients with medical disorders such as cancer, but evidence to guide its management is scarce. We aimed to assess the efficacy and cost of a nurse-delivered complex intervention that was designed to treat major depressive disorder in patients who have cancer.\n We did a randomised trial in a regional cancer centre in Scotland, UK. 200 outpatients who had cancer with a prognosis of greater than 6 months and major depressive disorder (identified by screening) were eligible and agreed to take part. Their mean age was 56.6 (SD 11.9) years, and 141 (71%) were women. We randomly assigned 99 of these participants to usual care, and 101 to usual care plus the intervention, with minimisation for sex, age, diagnosis, and extent of disease. The intervention was delivered by a cancer nurse at the centre over an average of seven sessions. The primary outcome was the difference in mean score on the self-reported Symptom Checklist-20 depression scale (range 0 to 4) at 3 months after randomisation. Analysis was by intention to treat. This trial is registered as ISRCTN84767225.\n Primary outcome data were missing for four patients. For 196 patients for whom we had data at 3 months, the adjusted difference in mean Symptom Checklist-20 depression score, between those who received the intervention and those who did not, was 0.34 (95% CI 0.13-0.55). This treatment effect was sustained at 6 and 12 months. The intervention also improved anxiety and fatigue but not pain or physical functioning. It cost an additional pound sterling 5278 (US$10 556) per quality-adjusted life-year gained.\n The intervention-Depression Care for People with Cancer-offers a model for the management of major depressive disorder in patients with cancer and other medical disorders who are attending specialist medical services that is feasible, acceptable, and potentially cost effective.", "Promising results were obtained in an earlier pilot study of a preventive intervention based on the principles of interpersonal psychotherapy to reduce the risk of postpartum major depressive disorder. In this study, the authors examined whether the intervention would reduce the risk of postpartum major depressive disorder in a larger sample of pregnant women.\n Ninety-nine pregnant women on public assistance who were assessed to be at risk for postpartum depression were randomly assigned to receive standard antenatal care plus the intervention or standard antenatal care only. Diagnostic interviews were administered 3 months after delivery to assess for major depressive disorder.\n Within 3 months after delivery, eight (20%) of the women in the standard antenatal care condition had developed postpartum major depressive disorder, compared with two (4%) in the intervention condition.\n This study provides further evidence for the efficacy of a brief intervention to reduce the occurrence of major depressive disorder among financially disadvantaged women during a postpartum period of 3 months.", "Few depressed older adults receive effective treatment in primary care settings.\n To determine the effectiveness of the Improving Mood-Promoting Access to Collaborative Treatment (IMPACT) collaborative care management program for late-life depression.\n Randomized controlled trial with recruitment from July 1999 to August 2001.\n Eighteen primary care clinics from 8 health care organizations in 5 states.\n A total of 1801 patients aged 60 years or older with major depression (17%), dysthymic disorder (30%), or both (53%).\n Patients were randomly assigned to the IMPACT intervention (n = 906) or to usual care (n = 895). Intervention patients had access for up to 12 months to a depression care manager who was supervised by a psychiatrist and a primary care expert and who offered education, care management, and support of antidepressant management by the patient's primary care physician or a brief psychotherapy for depression, Problem Solving Treatment in Primary Care.\n Assessments at baseline and at 3, 6, and 12 months for depression, depression treatments, satisfaction with care, functional impairment, and quality of life.\n At 12 months, 45% of intervention patients had a 50% or greater reduction in depressive symptoms from baseline compared with 19% of usual care participants (odds ratio [OR], 3.45; 95% confidence interval [CI], 2.71-4.38; P<.001). Intervention patients also experienced greater rates of depression treatment (OR, 2.98; 95% CI, 2.34-3.79; P<.001), more satisfaction with depression care (OR, 3.38; 95% CI, 2.66-4.30; P<.001), lower depression severity (range, 0-4; between-group difference, -0.4; 95% CI, -0.46 to -0.33; P<.001), less functional impairment (range, 0-10; between-group difference, -0.91; 95% CI, -1.19 to -0.64; P<.001), and greater quality of life (range, 0-10; between-group difference, 0.56; 95% CI, 0.32-0.79; P<.001) than participants assigned to the usual care group.\n The IMPACT collaborative care model appears to be feasible and significantly more effective than usual care for depression in a wide range of primary care practices.", "To standardise the delivery of a brief group cognitive behaviour therapy intervention (CBT-G). To apply the intervention in a research setting and to estimate its effect on recurrence rates in recently depressed older adults, in preparation for a definitive study.\n A CBT-G therapy manual was produced and the Cognitive Therapy Rating Scale (CTS-R) modified to assess therapy delivery. Forty-five adults aged 60 and over who had met ICD-10 criteria for major depression in the previous year and were still taking antidepressant medication were randomly allocated to CBT-G/antidepressant combination or antidepressant alone. Depression severity was measured at baseline, randomisation and 6 and 12 months after start of CBT-G using the Montgomery Asberg Rating Scale for Depression (MADRS).\n One-year recurrence rates on the MADRS were encouragingly lower in participants receiving CBT-G [5/18 (27.8%)] compared with controls [8/18 (44.4%)] although this did not achieve statistical significance (adjusted RR 0.70 [95% CI 0.26-1.94]). In contrast, overall scores on the secondary outcome measure, the Beck Depression Inventory, increased in participants receiving CBT-G. The CBT-G manual was successfully implemented and therapy delivery achieved an overall satisfactory level of competence. We believe that evaluation of this promising intervention in a full-scale trial is warranted.\n (c) 2008 John Wiley & Sons, Ltd.", "Depression is a disabling, prevalent condition. Physical activity programs may assist depression management in older people, ameliorate co-morbid conditions and reduce the need for antidepressants. The UPLIFT pilot study assessed the feasibility of older depressed people attending a community-based progressive resistance training (PRT) program. The study also aimed to determine whether PRT improves depressive status in older depressed patients.\n A randomised controlled trial was conducted. People aged > or = 65 years with depressive symptoms were recruited via general practices. Following baseline assessment, subjects were randomly allocated to attend a local PRT program three times per week for 10 weeks or a brief advice control group. Follow-up assessment of depressive status, physical and psychological health, functional and quality of life status occurred post intervention and at six months.\n Three hundred and forty six people responded to the study invitation, of whom 22% had depressive symptoms (Geriatric Depression Scale, GDS-30 score > or = 11). Thirty two people entered the trial. There were no significant group differences on the GDS at follow-up. At six months there was a trend for the PRT intervention group to have lower GDS scores than the comparison group, but this finding did not reach significance (p = 0.08). More of the PRT group (57%) had a reduction in depressive symptoms post program, compared to 44% of the control group. It was not possible to discern which specific components of the program influenced its impact, but in post hoc analyses, improvement in depressive status appeared to be associated with the number of exercise sessions completed (r = -0.8, p < 0.01).\n The UPLIFT pilot study confirmed that older people with depression can be successfully recruited to a community based PRT program. The program can be offered by existing community-based facilities, enabling its ongoing implementation for the potential benefit of other older people.", "There is a high prevalence of depression in patients with diabetes mellitus. Depression has been shown to be associated with poor self-management (adherence to diet, exercise, checking blood glucose levels) and high hemoglobin A1c (HbA1c) levels in patients with diabetes.\n To determine whether enhancing quality of care for depression improves both depression and diabetes outcomes in patients with depression and diabetes.\n Randomized controlled trial with recruitment from March 1, 2001, to May 31, 2002.\n Nine primary care clinics from a large health maintenance organization.\n A total of 329 patients with diabetes mellitus and comorbid major depression and/or dysthymia. Intervention Patients were randomly assigned to the Pathways case management intervention (n = 164) or usual care (n = 165). The intervention provided enhanced education and support of antidepressant medication treatment prescribed by the primary care physician or problem-solving therapy delivered in primary care.\n Independent blinded assessments at baseline and 3, 6, and 12 months of depression (Hopkins Symptom Checklist 90), global improvement, and satisfaction with care. Automated clinical data were used to evaluate adherence to antidepressant regimens, percentage receiving specialty mental health visits, and HbA1c levels.\n When compared with usual care patients, intervention patients showed greater improvement in adequacy of dosage of antidepressant medication treatment in the first 6-month period (odds ratio [OR], 4.15; 95% confidence interval [CI], 2.28-7.55) and the second 6-month period (OR, 2.90; 95% CI, 1.69-4.98), less depression severity over time (z = 2.84, P = .004), a higher rating of patient-rated global improvement at 6 months (intervention 69.4% vs usual care 39.3%; OR, 3.50; 95% CI, 2.16-5.68) and 12 months (intervention 71.9% vs usual care 42.3%; OR, 3.50; 95% CI, 2.14-5.72), and higher satisfaction with care at 6 months (OR, 2.01; 95% CI, 1.18-3.43) and 12 months (OR, 2.88; 95% CI, 1.67-4.97).

[ "Cirrhotic patients with upper gastrointestinal bleeding are prone to bacterial infection. The aim of this study was to investigate the efficacy of prophylactic intestinal decontamination with oral ciprofloxacin for the prevention of bacterial infections in cirrhotic patients with upper gastrointestinal bleeding.\n A total of 120 cirrhotic patients with acute upper gastrointestinal bleeding were enrolled. Sixty patients received ciprofloxacin 500 mg twice daily given orally or through nasogastric tube immediately after upper gastrointestinal endoscopic examination; drug administration continued for 7 days. The remaining 60 patients, who received placebo, served as controls.\n The incidence of proven bacterial infection in the ciprofloxacin-treated group was significantly lower than that of placebo group (10% vs 45%, p < 0.001). The incidences of bacteremia, spontaneous bacterial peritonitis, and urinary tract infection in the ciprofloxacin-treated group were significantly lower than those in the placebo group (0% vs 23%, 3.3% vs 13%, and 5% vs 18%, respectively; p < 0.05, respectively). Multivariate logistic regression analysis showed that a lack of prophylactic treatment with ciprofloxacin and severity of cirrhosis were the independent significant predictors for cirrhotic patients with acute gastrointestinal bleeding with infection.\n Prophylactic intestinal decontamination with oral ciprofloxacin is effective in the prevention of bacterial infections in patients with cirrhosis who were suffering from acute upper gastrointestinal hemorrhage.", "Bacterial infection may adversely affect the hemostasis of patients with gastroesophageal variceal bleeding (GEVB). Antibiotic prophylaxis can prevent bacterial infection in such patients, but its role in preventing rebleeding is unclear. Over a 25-month period, patients with acute GEVB but without evidence of bacterial infection were randomized to receive prophylactic antibiotics (ofloxacin 200 mg i.v. q12h for 2 days followed by oral ofloxacin 200 mg q12h for 5 days) or receive antibiotics only when infection became evident (on-demand group). Endoscopic therapy for the GEVB was performed immediately after infection work-up and randomization. Fifty-nine patients in the prophylactic group and 61 patients in the on-demand group were analyzed. Clinical and endoscopic characteristics of the gastroesophageal varices, time to endoscopic treatment, and period of follow-up were not different between the two groups. Antibiotic prophylaxis decreased infections (2/59 vs. 16/61; P <.002). The actuarial probability of rebleeding was higher in patients without prophylactic antibiotics (P =.0029). The difference of rebleeding was mostly due to early rebleeding within 7 days (4/12 vs. 21/27, P =.0221). The relative hazard of rebleeding within 7 days was 5.078 (95% CI: 1.854-13.908, P <.0001). The multivariate Cox regression indicated bacterial infection (relative hazard: 3.85, 95% CI: 1.85-13.90) and association with hepatocellular carcinoma (relative hazard: 2.46, 95% CI: 1.30-4.63) as independent factors predictive of rebleeding. Blood transfusion for rebleeding was also reduced in the prophylactic group (1.40 +/- 0.89 vs. 2.81 +/- 2.29 units, P <.05). There was no difference in survival between the two groups. In conclusion, antibiotic prophylaxis can prevent infection and rebleeding as well as decrease the amount of blood transfused for patients with acute GEVB following endoscopic treatment.", "Selective intestinal decontamination with norfloxacin is useful in the prevention of bacterial infections in cirrhotic patients with gastrointestinal bleeding. However, bleeding cirrhotic patients with ascites, encephalopathy, or shock are at high risk to develop bacterial infections in spite of prophylactic norfloxacin. The aim of this study was to assess whether the addition of intravenous ceftriaxone could improve the efficacy of prophylaxis with norfloxacin in these patients.\n Fifty-six cirrhotic patients with gastrointestinal hemorrhage and ascites, encephalopathy, or shock were randomized into two groups: Group 1 (n = 28) received oral norfloxacin 400 mg/12 h for 7 days, and group 2 (n = 28) received norfloxacin plus intravenous ceftriaxone 2 g daily during the first 3 days of admission.\n Ten patients were excluded because of community-acquired infection, surgery, or death within the first 24 h. The incidence of bacterial infections during hospitalization was 18.1% in group 1 and 12.5% in group 2 (p = NS). The incidence of severe infections (spontaneous bacterial peritonitis, bacteremia, or pneumonia) was also similar in both groups: 9% in group 1 versus 8.3% in group 2 (p = NS). There were no statistical differences between the two groups with respect to duration of hospitalization or mortality. The cost of antibiotic therapy (including prophylaxis and treatment of infections) was significantly higher in group 2.\n These results suggest that the addition of intravenous ceftriaxone during the first 3 days of hospitalization does not improve the cost-efficacy of oral norfloxacin in the prevention of bacterial infections in cirrhotic patients with gastrointestinal bleeding and high risk of infection.", "In cirrhotic patients with gastrointestinal hemorrhage, bacterial infections are frequent and play a significant role in mortality. We have previously found that patients with a Child-Pugh's class C or a rebleeding are a subgroup of cirrhotic patients with a high risk of infection. The aims of the study were (1) to validate these indicators and (2) to assess the effectiveness of a systemic antibiotic treatment in preventing bacterial infections in bleeding cirrhotics with a high risk of infection. One hundred and nineteen bleeding cirrhotic patients were divided into 3 groups. Patients with a Child-Pugh's class A-B and no rebleeding (i.e., with a low risk of infection) constituted group 1 (n = 55). Patients with a high risk of infection were randomly allocated to serve as controls (group 2, n = 34) or to receive the ciprofloxacin and a combination of amoxicillin and clavulanic acid for 3 days after hemorrhage (group 3, n = 30). This antibiotic prophylaxis was administered first intravenously and then orally when the bleeding was controlled. The study period was defined as 10 days after hemorrhage. Incidence of bacterial infections was significantly higher in patients from group 2 than in patients from group 1 (52.9% vs. 18.2%; P < .001). Moreover, infections were more severe in group 2: a sepsis syndrome or a septic shock developed in 66.7% of infected patients from this group, but in only 20% of infected patients from group 1. Incidence of bacterial infections was much lower in patients from group 3 than in those from group 2 (13.3% vs. 52.9%; P < .001). Eight patients from group 2 (23.5%) and 4 patients from group 3 (13.3%) died during the first four weeks (P-not significant). Septic shock was the cause of death in 3 patients from group 2 and in only 1 patient from group 3. The cost of antibiotic therapy, including antibiotic prophylaxis in group 3, was $208 +/- $63 per patient in group 2 and $167 +/- $42 per patient in group 3 (P < .05). We conclude that (1) patients with a Child-Pugh's class C and/or a rebleeding are a subgroup of cirrhotic patients with a high risk of infection after gastrointestinal hemorrhage and that (2) in these patients, a prophylactic treatment with systemic antibiotics is very effective in preventing bacterial infections.", "To determine the prevalence of bacterial infection in patients admitted to hospital with variceal bleeding in comparison with patients with liver cirrhosis admitted because of another reason. To compare the effect of orally administered antibiotics vs. intravenous antibiotics.\n Bacteriological investigation of blood culture, urine, throat smear, perianal smear and ascites (polymorphonuclear count as well in ascites) was made in 46 cirrhotic patients admitted to hospital with variceal bleeding and 48 cirrhotic patients admitted because of another reason. Bleeders were treated endoscopically (sclerotization) and pharmacologically (terlipressin 1 mg every 4 h for 5 days), and were randomly allocated to the treatment with oral norfloxacin (25 patients) or intravenous ampicillin/sulbactam (21 patients). Early and late mortalities were evaluated.\n The incidence of infection was high in both groups (63.0% bleeders vs. 54.2% controls), but bleeding patients more often had positive blood culture (17.3% vs. 8.6%) and statistically significantly more positive findings in the throat smears (36.9% vs. 17.3%, P=0.04), which gives the evidence of increased pathological colonization in these patients. No difference in survival was seen in patients with per-oral or intravenous administration of antibiotics.\n Bacterial infection was demonstrated in high percentage in patients with liver cirrhosis admitted to hospital. The administration of antibiotics is indicated in these patients. Intravenous application is probably of the same efficacy as per-oral one.", "In cirrhotic patients with esophageal variceal bleeding, bacterial infections are a frequent complication. Oral antibiotic prophylaxis decreases the incidence of bacterial infections. The administration of oral antibiotics, however, may be difficult in some cirrhotic patients with active bleeding. The purpose of this study was to assess the efficacy of prophylactic intravenous antibiotics for the prevention of bacterial infections in cirrhotic patients with esophageal variceal bleeding.\n From December 1998 to September 2001, a total of 40 consecutive cirrhotic patients with Child-Pugh class B or C were enrolled after emergent endoscopic esophageal variceal ligation (EVL) was taken because of esophageal variceal bleeding. Enrolled patients were randomized into a treatment group and a control group. The treatment group (n=20) received the intravenous ciprofloxacin 200mg IV q 12 hours for 3 days while the control group(n=20) didn,t.\n Bacterial infection developed in nine patients (45%) of the control group and only two patients (10%) in the treatment group. The incidence of bacterial infections was significantly lower in the treatment group than the control group (p < 0.005). The hospital cost and length of hospital stay decreased in the treatment group compared with the control group (p < 0.001). There were no differences in the hospital course and mortality within 30 days between the two groups.\n In cirrhotic patients with variceal bleeding and with Child-Pugh class B or C, the use of intravenous ciprofloxacin for 3 days after EVL was not only effective in the prevention of bacterial infections but also cost-effective.", "Infections are a frequent complication in cirrhotics, and gastrointestinal bleeding may increase the infection rate. Nonabsorbable antibiotics or quinolone have been employed to decrease the incidence of infection. Since most of these studies were performed in western countries, it is still unclear whether this holds true in our Taiwan cirrhotic patients. Thus we conducted this study using a different formula of antibiotics to evaluate the efficacy of reducing infection rates in cirrhotics with upper gastrointestinal bleeding.\n From July 1999 to August 2000, all cirrhotic in-patients presenting with upper gastrointestinal bleeding but without infection were enrolled. The patients should not have received antibiotics within 2 weeks before admission and should have expected life expectance more than 7 days. Eligible patients who had received endoscopy within 12 hours of hospitalization were randomly allocated into 2 groups. Group A received intravenous cefazolin 1 gm every 8 hours started before endoscopy. After 3 days of prophylactic parenteral antibiotics, antibiotics were shifted to oral cephalexin of 500 mg every 6 hours for 4 days. Group B served as control subjects. All patients received chest X-ray, blood and urine cultures, and ascites culture and sputum culture if ascites and sputum were found. Patients were excluded when initial blood, urine or ascites culture was positive for bacterial growth.\n Ninety-seven patients were included. Group A was comprised of 47 patients and Group B comprised of 50 patients. There was no significant difference in age, sex, Child-Pugh's score or initial hemoglobin between the 2 groups. Proved infection developed in 6 patients of Group B. By contrast, no proved infection was found in Group A. Three organisms belonged to gram-negative bacilli and 3 organisms were gram-positive cocci. The incidence of proved infection during hospitalization was 0% in Group A and 12.0% in Group B (p = 0.027). If possible infection cases (patient's body temperature more than 38 degrees C for more than 2 days) were included, the infection rate was 6.4% in Group A and 26% in Group B (p = 0.013). Infection-related mortality occurred in 2 patients in Group B, but none in Group A.\n Our prophylactic antibiotic treatment proved safe and effective in reducing the infection rate in cirrhotics with upper gastrointestinal bleeding.", "Patients with cirrhosis of the liver are prone to bacterial infections. Therapeutic interventions such as endoscopic sclerotherapy increase the risk of bacterial infections in these patients. Following insertion of a transjugular intrahepatic portosystemic shunt (TIPS), the incidence of severe bacterial infections was recently shown to be 20% after elective procedures. This finding suggests antibiotic prophylaxis with the TIPS procedure. Antibiotic prophylaxis using cefotiam or cefotaxime/ampicillin did not significantly reduce infectious complications. The aim of the present study was therefore to investigate the efficacy of two different doses of a long-acting cephalosporin in prevention of bacterial infection after TIPS.\n Eighty-two patients with cirrhosis (age: 52 +/- 2 years) who underwent elective TIPS were randomized to receive a single i.v. dose of either 1 g or 2 g Ceftriaxone 1 hour before the intervention. Patients with evidence of or suspected infections and patients on antibiotic therapy within 7 days prior to TIPS were excluded. Body temperature was monitored t.i.d. for 1 week and white blood count (WBC) and C-reactive protein (CRP) were determined before TIPS and 1 day and 1 week after TIPS.\n Only 2 of 82 patients (2.6%) showed signs of infection following TIPS insertion: One of 40 patients receiving 1 g Ceftriaxone and 1 of 42 patients receiving 2 g Ceftriaxone prior to TIPS developed temperature > 38.5 degrees C. In the latter patient this was due to pneumonia. This patient received antibiotic treatment with imipenem for 10 days. Temperature in the other patient normalized within 12 hours and he did not require antibiotic treatment. No significant differences in temperature, WBC and CRP between the different doses of Ceftriaxone were observed.\n Prophylactic treatment with Ceftriaxone reduces the reported incidence of bacterial infections after TIPS in patients with cirrhosis of the liver. Prophylaxis with 1 g Ceftriaxone seems as efficacious as 2 g.", "Bacterial infection may be a critical trigger for variceal bleeding. Antibiotic prophylaxis can prevent rebleeding in patients with acute gastroesophageal variceal bleeding (GEVB). The aim of the study was to compare prophylactic third generation cephalosporins with on-demand antibiotics for the prevention of gastroesophageal variceal rebleeding. In a prospective trial, patients with the first acute GEVB were randomly assigned to receive prophylactic antibiotics (intravenous cefotaxime 2 g q 8 hr for 7 days, prophylactic antibiotics group) or to receive the same antibiotics only when infection became evident (on-demand group). Sixty-two patients in the prophylactic group and 58 patients in the on-demand group were included for analysis. Antibiotic prophylaxis decreased infection (3.2% vs. 15.5%, p=0.026). The actuarial rebleeding rate in the prophylactic group was significantly lower than that in the on-demand group (33.9% vs. 62.1%, p=0.004). The difference of rebleeding rate was mostly due to early rebleeding within 6 weeks (4.8% vs. 20.7%, p=0.012). On multivariate analysis, antibiotic prophylaxis (relative hazard: 0.248, 95% confidence interval (CI): 0.067-0.919, p=0.037) and bacterial infection (relative hazard: 3.901, 95% CI: 1.053-14.448, p=0.042) were two independent determinants of early rebleeding. In conclusion, antibiotic prophylaxis using third generation cephalosporins can prevent bacterial infection and early rebleeding in patients with the first acute GEVB.", "Two hundred and twenty-nine patients were entered into a study to compare the effectiveness and safety of two single-shot antibiotic regimes in patients undergoing elective colorectal surgery in two district general hospitals. A single shot of intravenous (IV) latamoxef disodium was as effective as an IV combination of cefuroxime and metronidazole in control of wound infection following elective large bowel surgery when given as a bolus at the time of anaesthetic induction. The incidence of major wound infection was 6% and was evenly distributed in the two treatment groups. Half the major wound infections were associated with faecal fistulae. A single shot of IV antibiotic at the time of anaesthetic induction was safe, simple and an effective prophylaxis against major wound infection. There was a low incidence (1.3%) of serious postoperative bleeding and no serious adverse reactions were noted. The overall mortality was 9%. Death was significantly related to elderly patients, a poor performance status, operative contamination and wound infections.", "Oral norfloxacin is the standard of therapy in the prophylaxis of bacterial infections in cirrhotic patients with gastrointestinal hemorrhage. However, during the last years, the epidemiology of bacterial infections in cirrhosis has changed, with a higher incidence of infections caused by quinolone-resistant bacteria. This randomized controlled trial was aimed to compare oral norfloxacin vs intravenous ceftriaxone in the prophylaxis of bacterial infection in cirrhotic patients with gastrointestinal bleeding.\n One hundred eleven patients with advanced cirrhosis (at least 2 of the following: ascites, severe malnutrition, encephalopathy, or bilirubin >3 mg/dL) and gastrointestinal hemorrhage were randomly treated with oral norfloxacin (400 mg twice daily; n = 57) or intravenous ceftriaxone (1 g/day; n = 54) for 7 days. The end point of the trial was the prevention of bacterial infections within 10 days after inclusion.\n Clinical data were comparable between groups. The probability of developing proved or possible infections, proved infections, and spontaneous bacteremia or spontaneous bacterial peritonitis was significantly higher in patients receiving norfloxacin (33% vs 11%, P = .003; 26% vs 11%, P = .03; and 12% vs 2%, P = .03, respectively). The type of antibiotic used (norfloxacin), transfusion requirements at inclusion, and failure to control bleeding were independent predictors of infection. Seven gram-negative bacilli were isolated in the norfloxacin group, and 6 were quinolone resistant. Non-enterococcal streptococci were only isolated in the norfloxacin group. No difference in hospital mortality was observed between groups.\n Intravenous ceftriaxone is more effective than oral norfloxacin in the prophylaxis of bacterial infections in patients with advanced cirrhosis and hemorrhage.", "To investigate if oral, nonabsorbable antibiotics prevent bacterial infections in cirrhotics with gastrointestinal hemorrhage, 140 consecutive patients were randomly allocated into two groups: 68 patients (Group I) were given oral, non absorbable antibiotics (gentamicin + vancomycin + nystatin or neomycin + colistin + nystatin) from the inclusion into the trial up to 48 hr after cessation of the hemorrhage, or until emergency surgery or death in those cases who continued bleeding; and 72 patients (Group II) did not receive oral, nonabsorbable antibiotics. Both groups were similar in relation to clinical and laboratory data and characteristics of the hemorrhage. The incidence of infection was significantly lower in Group I than in Group II (11 patients in Group I and 25 in Group II developed proved infections; p less than 0.025). This difference was due to the fact that spontaneous bacteremia and peritonitis and urinary tract infection caused by enteric bacteria occurred almost exclusively in Group II. Two patients of Group I and 10 of Group II developed spontaneous bacteremia and/or peritonitis caused by enteric bacteria (p less than 0.025). These results indicate that prophylactic administration of oral, nonabsorbable antibiotics markedly reduces the incidence of infections caused by enteric bacteria in cirrhotic patients with gastrointestinal hemorrhage.", "Elective laparoscopic cholecystectomy (LC) has a low risk for infective complications, but many surgeons still use prophylactic antibiotics. The use of prophylactic antibiotics for LC is inconsistent and varies widely among surgeons.\n We performed a prospective double-blind randomized study of prophylactic antibiotics in elective LC. Antibiotics were was given first before the operation and then again 24 h afterward. Group A ( n = 49) received 2 g of cefotaxime; group B ( n = 43) received 10 ml of isotonic sodium chloride solution. A sample of bile was withdrawn by direct gallbladder puncture for anaerobic and aerobic cultures. Age, sex, weight, duration of surgery (DOS), presence of diabetes mellitus, American Society of Anesthesiologists (ASA) classification, gallbladder rupture, bile and/or stone spillage, gallbladder histological findings, findings from bile cultures positive for bacteria, episodes of colic within 30 days before surgery, length of stay (LOS), and number of septic complications were recorded for both groups.\n There was no differences between the two groups in terms of sex, weight, DOS, ASA score, gallbladder rupture, bile and/or stone spillage, gallbladder histological findings, findings from bile cultures positive for bacteria, or LOS. One infection occurred in the antibiotic prophylaxis group (2.04%); in the patients not receiving antibiotics, there was one other infection (2.32%). There was no statistical difference between the two groups in infective complications.\n In patients undergoing elective LC, antibiotic prophylaxis is justified only in high-risk patients. In all other patients, antibiotic prophylaxis does not seem to affect the incidence of postoperative infective complications. In low-risk patients, eliminating the unnecessary use of prophylactic antibiotics would result in a cost reduction; moreover, it would lower the risk of adverse reaction and reduce microbial resistance.", "The use of prophylactic antibiotics in addition to mechanical cleansing is the current standard of care prior to colonic surgery. The question of whether the antibiotics should be administered intravenously or orally, or by both routes, remains controversial. Our aim was to compare three methods of prophylactic antibiotic administration in elective colorectal surgery.\n Three hundred consecutive elective colorectal resections were studied. All patients had preoperative mechanical colon cleansing with oral sodium phosphate and intravenous antibiotic prophylaxis with cefoxitin (one dose before skin incision and two postoperative doses). Patients were randomised to one of the following three groups: group A: three doses of oral antibiotic (neomycin and metronidazole) at the time of mechanical colon cleansing; group B: one dose of oral antibiotic; group C: no oral antibiotics. All patients were followed during their hospital stay and at 7, 14 and 30 days post-surgery.\n Vomiting occurred in 31%, 11% and 9% of the studied patients (groups A, B and C, respectively) (p<0.001). Nausea was present in 44%, 18% and 13% of patients (p<0.001). Abdominal pain was recorded in 13%, 10% and 4% of patients (p: 0.077). Wound infection was present in 7%, 8% and 6% and suture dehiscence occurred in 2%, 2% and 3% of the patients in the three groups (no differences among them). Neither were differences found among the three groups in terms of urinary infections, pneumonia, postoperative ileus or intra-abdominal abscess.\n The addition of three doses of oral antibiotics to intravenous antibiotic prophylaxis is associated with lower patient tolerance in terms of increased nausea, vomiting and abdominal pain, and has shown no advantages in the prevention of postoperative septic complications. Therefore, we recommend that oral antibiotics should not be used prior to colorectal surgery.", "This randomized prospective study was aimed at assessing the efficiency of a systemic antibiotic therapy for the prevention of bacterial infections in cirrhotic patients with gastrointestinal hemorrhage by ruptured esophageal varices. For 15 mo, all patients hospitalized with no infection on admission, were included in the study. Starting on admission day, patients in group A received ofloxacin (400 mg/day) for 10 days, first intravenously then orally. They also received an intravenous bolus of amoxicillin plus clavulanic acid (1 g) before each endoscopy performed during hemorrhage. Patients in group B received antibiotic therapy only in cases of established or suspected infection. Chest X-ray, blood culture, urine culture and sputum and ascitic fluid culture were performed every day for 7 days, then every other day for the next 7 days. A bronchial sampling was performed with the Wimberley technique on patients with endotracheal intubation. Ninety-one patients (55 men, 54 +/- 11 years, 78% Child Pugh class C) were included in the study (46 in group A, 45 in group B). Group A showed a lower incidence of bacterial infections than group B (20% vs. 66%; p < 0.001). Breakdown of positive bacteriological sampling was as follows: blood (6 vs. 17), ascites (3 vs. 7), lungs (2 vs. 18), urine (1 vs. 10). The 2-wk mortality rate was 24% in group A and 35% in group B." ]

[ "Elective single embryo transfer (eSET) in a selected group of patients (i.e. young patients with at least one good quality embryo) reduces the number of multiple pregnancies in an IVF programme. However, the reduced overall multiple pregnancy rate (PR) is still unacceptably high. Therefore, a randomized controlled trial (RCT) was conducted comparing eSET and double embryo transfer (DET) in an unselected group of patients (i.e. irrespective of the woman's age or embryo quality).\n Consenting unselected patients were randomized between eSET (RCT-eSET) (n = 154) or DET (RCT-DET) (n = 154). Randomization was performed just prior to the first embryo transfer, provided that at least two 2PN zygotes were available. Non-participants received our standard transfer policy [SP-eSET in a selected group of patients (n = 100), otherwise SP-DET (n = 122)].\n The ongoing PR after RCT-eSET was significantly lower as compared with RCT-DET (21.4 versus 40.3%) and the twin PR was reduced from 21.0% after RCT-DET to 0% after RCT-eSET. The ongoing PRs after SP-eSET and SP-DET did not differ significantly (33.0 versus 30.3%), with an overall twin PR of 12.9%.\n To avoid twin pregnancies resulting from an IVF treatment, eSET should be applied in all patients. The consequence would be a halving of the ongoing PR as compared with applying a DET policy in all patients. The transfer of one embryo in a selected group of good prognosis patients leads to a less drastic reduction in PR but maintains a twin PR of 12.9%.", "With the aim of reducing the number of multiple pregnancies after IVF we investigated the effectiveness of two cycles with single embryo transfer (SET) and one cycle with double embryo transfer (DET) after IVF and calculated the cost-effectiveness of both strategies. Methods: A randomized controlled trial was performed in 107 women, aged <35 years, in their first IVF cycle, with at least one good quality embryo. They were randomized to the SET (n = 54) or DET (n = 53) group using a computer-generated random block number table, stratified for primary or secondary infertility.\n The cumulative live birth rates per woman randomized of two consecutive cycles of SET [41%; 95% confidence interval (CI) 27-54] versus one cycle of DET (36%; 95% CI 23-49) were comparable, whereas the multiple pregnancy rate was significantly higher: 37% (95% CI 15-59) in the DET and 0% in the in the SET group (P = 0.002). Combining the medical costs of the IVF treatments (where 1.5 more SET cycles were required to achieve each live birth) and of pregnancies up to 6 weeks after delivery, the total medical costs of DET per live birth were 13,680 and 13,438 for SET.\n Two cycles with SET were equally effective as one cycle with DET, and the medical costs per live birth up to 6 weeks after delivery were the same. However, if lifetime costs for severe handicaps are included, more than 7000 per live birth will be saved after implementing SET. Because of the high probability of multiple pregnancies in this group of IVF patients, only SET should be performed.", "In a prospective study, we compared two protocols of ovulation stimulation, the clomiphene citrate and human menopausal gonadotropin (hMG) versus D-triptorelin, a long-acting gonadotropin-releasing hormone (GnRH) agonist and hMG in 324 couples having their first in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI) program, in terms of pregnancy rates and cost-effectiveness of drugs used. The GnRH agonist/hMG group was characterized by a greater mean number of ampoules of hMG used (31.7 versus 10.2), a larger number of oocytes collected (10.4 versus 4.2), and a larger number of embryos obtained (5.8 versus 2.9). With the policy of transferring only two of the best quality embryos, the mean number of embryos replaced were comparable (1.8 in clomiphene citrate/hMG and 1.9 in GnRH agonist/hMG group). The percentage of patients reaching embryo transfer was lower in the clomiphene citrate/hMG than in the GnRH agonist/hMG group (84.1% versus 93.1%, respectively). However, the combined results of the IVF and ICSI procedure in terms of pregnancy rate, both per patient and per embryo transfer were better, though not significantly in the clomiphene citrate/hMG than in GnRH agonist/hMG group (25.0% and 29.7% versus 23.7% and 25.5%, respectively). Similarly, the implantation rate was better (19.0% versus 13.5%, respectively). With the use of clomiphene citrate/hMG, a fivefold less costly drug regimen, we obtained pregnancy rates equivalent to those gained using GnRH agonist/hMG in our IVF/ICSI program.", "To compare luteal phase leuprolide acetate (LA) initiated pituitary down regulation followed by human menopausal gonadotropins (hMG) versus clomiphene citrate (CC) and hMG for follicular recruitment and oocyte maturation before in vitro fertilization (IVF).\n Randomized, prospective comparison in first cycles of IVF.\n University Hospital, a tertiary referral center offering assisted reproductive technologies.\n Participants were couples undergoing their first ever cycle of IVF and consenting to participation in the trial.\n Luteal phase initiated LA/hMG was associated with a lower probability of cycle cancellation, improved folliculogenesis, and a higher probability of embryo transfer (ET) compared with CC/hMG alone. Implantation rates were not different.\n A higher rate of ET with LA/hMG suggests that gonadotropin-releasing hormone agonist for the induction of folliculogenesis before IVF may be appropriate.", "To compare the classic clomiphene citrate (CC) and hMG regime for ovarian stimulation before IVF in women who received hMG post-long protocol down-regulation with either 3 mg triptorelin [INN] IM or 150 mg buserelin acetate four times daily intranasally. Furthermore, if possible, to determine the preferred method of down-regulation.\n A prospective study of 150 women randomized blind to the clinician to one of three alternative ovarian stimulation regimes when passing for the first time through an IVF program during 1992.\n Triptorelin [INN] down-regulated significantly more quickly than buserelin acetate. The non-down-regulated group CC and hMG used significantly less hMG in a shorter time. In these women LH levels at hCG administration were significantly higher. No other intergroup differences were found. Pregnancy and take-home baby rates for the overall study were, respectively, 32%:25% (per cycle) and 42%:33%; (per ET) for the triptorelin [INN] group 28%:22% and 39%:31%; the CC group 32%:24% and 46%:34%; and the buserelin acetate group 34%:28% and 42%:34%.\n Triptorelin [INN] and buserelin acetate were comparable in all parameters except down-regulation. The former was significantly quicker and more sure. In none of the clinical end points measured, however, was the classic CC and hMG non-down-regulation regime significantly less effective or troublesome than where down-regulation was used. These results therefore show that although indications for down-regulation before IVF exist, it should not be used on all patients.", "The main reason for adverse treatment outcome in assisted reproduction is the high rate of multiple pregnancies. The only strategy to avoid dizygotic twins is to transfer one embryo at a time.\n A total of 144 women, who had had at least four good quality embryos available after IVF/intracytoplasmic sperm injection (ICSI) and who had no more than one previous failed treatment cycle, were randomized to have either one or two embryos transferred. The treatment outcomes including those after frozen embryo transfer were compared between these groups.\n The clinical pregnancy rate per transfer was 32.4% in the one embryo transfer group and 47.1% in the two embryo transfer group, the difference being not significant. Eleven twin deliveries (n = 39) occurred in the two embryo transfer group and there was one pair of monozygotic twins in the one embryo transfer group. The cumulative pregnancy rate per patient after transfer of fresh and frozen embryos was 47.3% in the one embryo transfer group and 58.6% in the two embryo transfer group.\n Our results indicate that among women who have good quality embryos in their first IVF/ICSI, good treatment results can be achieved. They support the idea of changing embryo transfer policy towards one embryo transfer without any remarkable decrease in the success rate, while dizygotic twins can be avoided." ]

Forty-eight healthy smokers who smoked at least one pack per day were studied at an outpatient smoking cessation research clinic. The subjects ranged in age from 20 to 40 years. Intervention with the nicotine skin patch (6 to 8 weeks) plus oral mecamylamine (2.5 to 5 mg twice a day for 5 weeks) was compared to nicotine patch plus placebo. Mecamylamine treatment began 2 weeks before smoking cessation. The primary outcome was continuous abstinence through 7 weeks after cessation (1 week after treatment), confirmed by expired air carbon monoxide measurements. Secondary measures included point abstinence at 7 weeks, continuous abstinence at 6- and 12-month follow-up, and self-reported withdrawal symptoms.\n The continuous abstinence rate at 7 weeks was three times higher in the mecamylamine condition: 50% versus 16.7%, p = 0.015. Point abstinence at 7 weeks was 58% for mecamylamine versus 29% for placebo, p = 0.044. At follow-up, continuous abstinence remained higher for mecamylamine: 37.5% versus 12.5% at 6 months (p = 0.046) and 37.5% versus 4.2% at 12 months (p = 0.004).

Fifty-one (75%) of the 68 workers starting postexposure prophylaxis reported one or more side effects. Side effects were more common among those taking three drugs. Many workers failed to complete the recommended 28-day regimen because of the side effects of the various treatments. The estimated mean cost for evaluations, prophylaxis, and monitoring of exposed workers was $669 per reported exposure.

The case patients were those who became seropositive after exposure to HIV, as reported by national surveillance systems in France, Italy, the United Kingdom, and the United States. The controls were health care workers in a prospective surveillance project who were exposed to HIV but did not seroconvert.\n Logistic-regression analysis based on 33 case patients and 665 controls showed that significant risk factors for seroconversion were deep injury (odds ratio= 15; 95 percent confidence interval, 6.0 to 41), injury with a device that was visibly contaminated with the source patient's blood (odds ratio= 6.2; 95 percent confidence interval, 2.2 to 21), a procedure involving a needle placed in the source patient's artery or vein (odds ratio=4.3; 95 percent confidence interval, 1.7 to 12), and exposure to a source patient who died of the acquired immunodeficiency syndrome within two months afterward (odds ratio=5.6; 95 percent confidence interval, 2.0 to 16). The case patients were significantly less likely than the controls to have taken zidovudine after the exposure (odds ratio=0.19; 95 percent confidence interval, 0.06 to 0.52).\n The risk of HIV infection after percutaneous exposure increases with a larger volume of blood and, probably, a higher titer of HIV in the source patient's blood.

Our aim was to determine if an adherence intervention could improve adherence among patients attending an ambulatory care clinic at a large public hospital. The intervention was delivered by a multidisciplinary team of health care professionals and consisted of education coupled with the provision of devices designed to assist patient memory and adherence.

The study was conducted as a controlled trial, with an intervention group and an observation group. There was a 34% reduction in expected sickness in children in the intervention group. In the categories diarrhoea and eye-infection there was a significant drop in sickness. We conclude that broad intervention concerning hand-hygiene has a positive effect on sickness in children attending day-care centres.", "Several studies have indicated a connection between hand sanitization and infection control in numerous settings such as extended care facilities, schools, and hospitals. The purpose of this study was to assess the effectiveness of both a hand-hygiene message campaign and the use of an alcohol gel hand sanitizer in decreasing the incidence of upper-respiratory illness among students living in university residence halls.\n This study involved a total of 430 students recruited from 4 residence halls during the fall semester at the University of Colorado at the Boulder campus. Dormitories were paired into control and product groups. In the product groups, alcohol gel hand-sanitizer dispensers were installed in every room, bathroom, and dining hall. The data were statistically analyzed for the differences between product and control groups in reported symptoms, illness rates, and absenteeism from classes.\n The overall increase in hand-hygiene behavior and reduction in symptoms, illness rates, and absenteeism between the product group and control group was statistically significant. Reductions in upper respiratory-illness symptoms ranged from 14.8% to 39.9%. Total improvement in illness rate was 20%. The product group had 43% less missed school/work days.\n Hand-hygiene practices were improved with increased frequency of handwashing through increasing awareness of the importance of hand hygiene, and the use of alcohol gel hand sanitizer in university dormitories. This resulted in fewer upper respiratory-illness symptoms, lower illness rates, and lower absenteeism." ]

[ "We tested if fetal pulse oximetry in addition to electronic fetal monitoring (CTG) and scalp blood sampling improves the accuracy of fetal assessment and allows safe reduction of operative deliveries (-50%) and scalp blood sampling (-50%) performed because of nonreassuring fetal status. Study design A randomized controlled trial was conducted in 146 patients with term pregnancies in active labor and abnormal fetal heart rate patterns: 73 had electronic fetal heart rate monitoring (CTG) and fetal scalp blood sampling (control group), 73 had CTG, fetal scalp blood sampling, and continuous fetal pulse oximetry (study group).\n There was a reduction of -50% in operative deliveries and fetal scalp blood sampling performed because of nonreassuring fetal status in the study group: operative deliveries, study versus control 25/49 (P </= .001); fetal scalp sampling, study versus control 32/64 (P </= .001). An increase in cesarean sections because of dystocia in the study group did not change the net number of operative deliveries. There was no difference between the 2 groups in adverse maternal or neonatal outcomes, as well as for the end points of metabolic acidosis and need for resuscitation.\n There was a safe reduction in operative deliveries (-50%) and scalp blood sampling (-50%) performed because of nonreassuring fetal status. The increase in cesarean sections because of dystocia in the study group was a well-documented arrest of labor, but it did not change the total number of operative deliveries in this group.", "Recent developments permit the use of pulse oximetry to evaluate fetal oxygenation in labor. We tested the hypothesis that the addition of fetal pulse oximetry in the evaluation of abnormal fetal heart rate patterns in labor improves the accuracy of fetal assessment and allows safe reduction of cesarean deliveries performed because of nonreassuring fetal status.\n A randomized, controlled trial was conducted concurrently in 9 centers. The patients had term pregnancies and were in active labor when abnormal fetal heart rate patterns developed. The patients were randomized to electronic fetal heart rate monitoring alone (control group) or to the combination of electronic fetal monitoring and continuous fetal pulse oximetry (study group). The primary outcome was a reduction in cesarean deliveries for nonreassuring fetal status as a measure of improved accuracy of assessment of fetal oxygenation.\n A total of 1010 patients were randomized, 502 to the control group and 508 to the study group. There was a reduction of >50% in the number of cesarean deliveries performed because of nonreassuring fetal status in the study group (study, 4. 5%; vs. control, 10.2%; P =.007). However, there was no net difference in overall cesarean delivery rates (study, n = 147 [29%]; vs. control, 130 [26%]; P = .49) because of an increase in cesarean deliveries performed because of dystocia in the study group. In a blinded partogram analysis 89% of the study patients and 91% of the control patients who had a cesarean delivery because of dystocia met defined criteria for actual dystocia. There was no difference between the 2 groups in adverse maternal or neonatal outcomes. In terms of the operative intervention for nonreassuring fetal status, there was an improvement in both the sensitivity and the specificity for the study group compared with the control group for the end points of metabolic acidosis and need for resuscitation.\n The study confirmed its primary hypothesis of a safe reduction in cesarean deliveries performed because of nonreassuring fetal status. However, the addition of fetal pulse oximetry did not result in an overall reduction in cesarean deliveries. The increase in cesarean deliveries because of dystocia in the study group did appear to result from a well-documented arrest of labor. Fetal pulse oximetry improved the obstetrician's ability to more appropriately intervene by cesarean or operative vaginal delivery for fetuses who were actually depressed and acidotic. The unexpected increase in operative delivery for dystocia in the study group is of concern and remains to be explained.", "The purpose of this study was to determine the clinical role of fetal pulse oximetry to reduce cesarean delivery for a nonreassuring fetal heart rate tracing.\n Singletons > or =28 weeks were randomized to fetal pulse oximetry plus electronic fetal heart rate monitoring (monitoring + fetal pulse oximetry) or monitoring alone.\n Overall, 360 women in labor were recruited: 150 cases with monitoring+fetal pulse oximetry and 177 cases with monitoring alone were analyzed. Most demographic, obstetric, and neonatal characteristics were similar. Specifically, the gestational age, cervical dilation, and station of the fetal head were not differential factors. In addition, cesarean delivery for nonreassuring fetal heart rate tracing was not different between the group with monitoring+fetal pulse oximetry (29%) and the group with monitoring alone (32%; relative risk, 0.95; 95% CI, 0.75, 1.22). Likewise, cesarean delivery for arrest disorder was similar between the group with monitoring+fetal pulse oximetry (22%) and the group with monitoring alone (23%; relative risk, 1.05; 95% CI, 0.79, 1.44). However, the decision-to-incision time was shorter for the group with monitoring+fetal pulse oximetry (17.8 +/- 8.2 min) than for the group with monitoring alone (27.7 +/- 13.9 min; P < .0001).\n The use of fetal pulse oximetry with electronic fetal heart rate monitoring does not decrease the rate of cesarean delivery, although it does alter the decision-to-incision time.", "Knowledge of fetal oxygen saturation, as an adjunct to electronic fetal monitoring, may be associated with a significant change in the rate of cesarean deliveries or the infant's condition at birth.\n We randomly assigned 5341 nulliparous women who were at term and in early labor to either \"open\" or \"masked\" fetal pulse oximetry. In the open group, fetal oxygen saturation values were displayed to the clinician. In the masked group, the fetal oxygen sensor was inserted and the values were recorded by computer, but the data were hidden. Labor complicated by a nonreassuring fetal heart rate before randomization was documented for subsequent analysis.\n There was no significant difference in the overall rates of cesarean delivery between the open and masked groups (26.3% and 27.5%, respectively; P=0.31). The rates of cesarean delivery associated with the separate indications of a nonreassuring fetal heart rate (7.1% and 7.9%, respectively; P=0.30) and dystocia (18.6% and 19.2%, respectively; P=0.59) were similar between the two groups. Similar findings were observed in the subgroup of 2168 women in whom a nonreassuring fetal heart rate was detected before randomization. The condition of the infants at birth did not differ significantly between the two groups.\n Knowledge of the fetal oxygen saturation is not associated with a reduction in the rate of cesarean delivery or with improvement in the condition of the newborn.

The caesarean section rate (6.4 versus 4.7%) and the VO rate (9.5 versus 10.7%) were also similar in the STAN and CTG groups. The incidence of FBS was lower (P < 0.001) in the STAN group (7.0%) than in the CTG group (15.6%).\n Intrapartum fetal monitoring by means of automatic STAN did not improve the neonatal outcome or decrease the caesarean section rate. However, the need for FBS during labour was lower in the STAN group." ]
