[Title]: Postoperative pain management using intravenous patient-controlled analgesia for pediatric patients.
[Abstract]: Pain control is an important consideration after any surgical procedures. Especially in children, more attention and care are needed during the period of postoperative pain control, which must be both sufficiently safe and effective. In this respect, intravenous patient-controlled analgesia provides improved titration of analgesic drugs, thereby maintaining optimal analgesic status with few side effects. Thirty pediatric patients were randomly divided into two groups: the intravenous patient-controlled analgesia group (with nalbuphine HCl and ketorolac tromethamine) and the conventional pethidine HCl intramuscular group. The degree of analgesia was assessed every 4 hours until the second postoperative day. The intravenous patient-controlled analgesia group had significantly lower pain scores and took less time until they were able to walk to the bathroom, but as many side effects as the control group. We concluded that intravenous patient-controlled analgesia is safe and effective for pediatric patients who have moderate to severe pain after operations such as rib cartilage graft, iliac bone graft, and large flap surgeries.

[Title]: Improved efficacy and safety of controlled-release diltiazem compared to nifedipine may be related to its negative chronotropic effect.
[Abstract]: The objective of this study was to assess the safety and efficacy of long-acting preparations of two commonly used calcium antagonists with particular reference to their effects on heart rate. Twenty patients with chronic stable angina were recruited to a double-blind, double-dummy crossover study of controlled-release diltiazem (diltiazem CR) versus sustained-release nifedipine (nifedipine SR) and underwent clinical assessment, symptom and adverse event reporting, and repeated treadmill exercise tests over a 10- to 11-week period. The main outcome measures were heart rate at rest and exercise, incidence of angina and nitroglycerin use, treadmill exercise performance (duration, time to angina, time to 1-mm ST-segment depression, heart rate at equivalent maximal exercise, and maximal ST-segment depression), and adverse events. Diltiazem CR significantly reduced heart rate at rest and equivalent exercise and incidence of angina and nitroglycerin use compared with nifedipine SR. Exercise duration time to angina and time to 1-mm ST-segment depression (but not maximal ST-segment depression) were all significantly improved by diltiazem CR. Diltiazem CR also caused significantly fewer adverse events than nifedipine SR. Calcium antagonists with negative chronotropic effects (eg, diltiazem CR) are safer and more efficacious as monotherapy in chronic stable angina than dihydropyridines (eg, nifedipine SR) even when a long-acting formulation of the latter is used.

[Title]: The effects of diltiazem on hemodynamics and seizure duration during electroconvulsive therapy.
[Abstract]: UNLABELLED: Electroconvulsive therapy (ECT) is often associated with acute hyperdynamic responses, and we hypothesize that diltiazem can blunt this response. We measured the effect of a 10-mg dose of diltiazem on heart rate and mean arterial pressure during ECT. Furthermore, we assessed seizure duration by using both the cuff method and two-lead electroencephalogram. We studied 18 patients with a randomized, double-blinded, placebo-controlled cross-over study design. Diltiazem significantly reduced heart rate and mean arterial pressure just after medication, and it also significantly reduced the increases in these variables after ECT, as compared with the placebo. The use of diltiazem was, however, associated with a shortened seizure duration, possibly making ECT less effective. Because of the reduction in seizure duration, the routine administration of diltiazem may not be advisable because it can possibly interfere with the psychotherapeutic efficacy of ECT. However, diltiazem medication for ECT is potentially useful for reducing tachycardia and hypertension in high-risk patients. IMPLICATIONS: Diltiazem can blunt acute hyperdynamic responses after electroconvulsive therapy, but seizure duration is also significantly reduced, possibly making this therapy less effective.

[Title]: Carboplatin and vinorelbine in untreated locally advanced and metastatic non-small cell lung cancer.
[Abstract]: The aim of this study was to assess the activity and toxicity of carboplatin/vinorelbine combination chemotherapy in unresectable locally advanced and metastatic non-small cell lung cancer. Between April 1997 and June 1999 30 patients (22 M, eight F, median age 62) received treatment with carboplatin AUC 6 on day 1, and vinorelbine 25mg/m(2) on days 1, 8 and 15. Treatment was given every 28 days for six cycles unless progressive disease occurred. Twenty-three patients (77%) had stage IV disease, and seven (23%) stage IIIB. Ninety-three percent were WHO performance status 0-1. Twenty-three patients were fully assessable. Nine patients achieved partial responses (9/23, 39%) for an overall objective response rate of 9/30 (30%; 95% CI 15-49%). The median duration of response was 2.75 months (range 1-13 months). The median progression-free survival was 2 months and the median survival 5.25 months. The actuarial 1-year survival was 20%. The median number of cycles completed was two (range 1-6). Day 15 vinorelbine was administered in only 18% of cycles. The main toxicity was myelosuppression. WHO grade III/IV neutropenia was experienced in 50% of patients, however, there were only three episodes of febrile neutropenia. Eight patients required blood transfusion and one developed grade III thrombocytopenia. Treatment was ceased in one patient because of grade IV autonomic neuropathy. No patient had significant nausea and vomiting. There were no treatment-related deaths. These results indicate that carboplatin/vinorelbine is well tolerated and has similar activity to cisplatin/vinorelbine in patients with unresectable non-small cell lung cancer, however, the median survival was considerably shorter.

[Title]: Effect of acute blood pressure reduction on endothelial function in the brachial artery of patients with essential hypertension.
[Abstract]: OBJECTIVES: To evaluate the effect of acute blood pressure reduction on endothelium-dependent vasodilation in the peripheral circulation of essential hypertensive patients. DESIGN: A parallel group study; endothelial function measured in 64 essential hypertensive patients before and after (2 h) treatment with nifedipine (20 mg, n = 32) or captopril (50 mg, n = 32), p.o., randomly assigned. METHODS: In hypertensive patients, we evaluated flow-mediated, endothelium-dependent dilation (FMD, high resolution ultrasound) of the brachial artery compared with endothelium-independent response to glyceryl trinitrate (GTN, 25 microg s.l.). Automatic computerized analysis was used to measure brachial artery diameter on end-diastolic frames acquired every second during the study. Sixty-six healthy normotensive subjects were also evaluated to assess the presence of endothelial dysfunction in hypertensive patients. RESULTS: Hypertensive patients showed a significantly (P< 0.01) lower FMD (5.9 +/- 2.5%) as compared to healthy controls (7.7 +/- 3.8%). The response to GTN was similar in normotensive subjects (7.5 +/- 3.1%) and hypertensive patients (7.2 +/- 6.5%). At baseline brachial artery diameter, FMD and response to GTN were similar in the nifedipine- and captopril-treated groups. Nifedipine and captopril similarly reduced blood pressure, but only nifedipine increased heart rate. Acute nifedipine, but not captopril, significantly (P< 0.01) increased brachial artery diameter, while FMD and response to GTN were not modified after nifedipine or captopril. CONCLUSIONS: Endothelial dysfunction in the brachial artery of essential hypertensive patients is not improved by acute blood pressure reduction.

[Title]: A randomized double-blind study of risperidone and olanzapine in the treatment of schizophrenia or schizoaffective disorder.
[Abstract]: OBJECTIVE: The safety and efficacy of risperidone and olanzapine were compared in a double-blind trial that used doses widely accepted in clinical practice. METHOD: Subjects (N=377) who met DSM-IV criteria for schizophrenia or schizoaffective disorder were randomly assigned to receive 2-6 mg/day of risperidone (mean modal dose=4.8 mg/day) or 5-20 mg/day of olanzapine (mean modal dose=12.4 mg/day) for 8 weeks. RESULTS: The two study groups were similar at baseline except that the olanzapine group was slightly younger than the risperidone group. Seventy-five percent of the participants completed the trial, with no between-treatment differences in the proportion of dropouts. Similar proportions of the risperidone and olanzapine groups reported extrapyramidal symptoms (24% and 20%, respectively). Severity of extrapyramidal symptoms was low in both groups, with no between-group differences. Total Positive and Negative Syndrome Scale scores and scores on the five Positive and Negative Syndrome Scale factors were improved in both groups at week 8 (subjects who completed the study) and endpoint (all subjects, including dropouts). There were overall between-treatment differences in efficacy. Comparison of individual factors found no significant differences at endpoint; at week 8, however, improvements on Positive and Negative Syndrome Scale factors for positive symptoms and anxiety/depression were greater with risperidone than olanzapine. An increase in body weight of > or =7% was seen in 27% of olanzapine participants and 12% of risperidone participants. CONCLUSIONS: Both treatments were well tolerated and efficacious. The frequency and severity of extrapyramidal symptoms were similar in the two treatment groups. Greater reductions in severity of positive and affective symptoms were seen with risperidone than with olanzapine treatment among study completers. There was no measure on which olanzapine was superior. Greater weight gain was associated with olanzapine than with risperidone treatment.

[Title]: Reversal of diminished inhibitory sensory gating in cocaine addicts by a nicotinic cholinergic mechanism.
[Abstract]: Cocaine addiction, as with other stimulant abuse, produces psychotic symptoms. Although often moderate to mild in severity, these symptoms are, nevertheless, associated with poorer over-all outcome. Recent studies suggest diminished nicotinic cholinergic neurotransmission as a mechanism of a physiological deficit found in schizophrenia, failure of auditory sensory inhibition. Diminished inhibitory sensory gating also occurs in cocaine addicts, probably because of their increased catecholaminergic neurotransmission, which blocks the inhibition. In the present study, 11 cocaine addicts in the first week of detoxification were recorded electrophysiologically, after which the effects of 6 mg of nicotine gum, were assessed in a double-blind placebo-controlled crossover design. The test was repeated 10 days later. Treatment with nicotine, but not placebo, briefly reversed the inhibitory abnormality on both test days. Although nicotine itself may not be a desirable therapeutic agent, because desensitization of nicotinic receptors limits the time course of its effect, the study identifies a previously unexploited therapeutic target for new drug development for the neuropsychiatric sequelae of cocaine addiction.

[Title]: High incidence of central nervous system involvement in patients with metastatic or locally advanced breast cancer treated with epirubicin and docetaxel.
[Abstract]: BACKGROUND: Clinically overt central nervous system (CNS) involvement occurs in 10%-15% of patients with advanced breast cancer. PATIENTS AND METHODS: The International Breast Cancer Study Group (IBCSG) conducted a dose-finding phase I trial of epirubicin (E) and docetaxel (D) as first-line therapy in advanced breast cancer patients. The study was expanded into a phase II at the recommended doses of E 90 mg/m2 and D 75 mg/m2 every three weeks. From July 1996 to May 1998, a total of 92 patients (median age 50 years) entered the two studies. RESULTS: Twenty-eight out of ninety-two patients treated with the combination of E and D (30%) developed CNS metastases (95% confidence limits, 26%-35%), which were cerebral in twenty-five patients, leptomeningeal in two, and both in one. Of these 28 patients, 19 (68%) had an objective response. Median time for the development of CNS metastases from the start of chemotherapy was 15 months (range 5-42), if excluding the 6 patients presenting CNS progression within 3 months from start of treatment. It is notable that 11 patients (39%) had progression in the CNS only. Median survival from appearance of brain metastases in the whole group was only three months (range 1-22). C-erbB-2 overexpression was found in 14 out of 16 patients (87%) in whom the assay was performed (3+ in 10, 2+ in 1 and 1+ in 3 cases). CONCLUSIONS: As anthracycline- and taxane-containing regimens are increasingly used both in the metastatic and in the adjuvant setting, a careful monitoring of any neurological symptom is advisable. Our preliminary observation on the possible increase of incidence of CNS involvement in patients with advanced breast cancer receiving this effective drug combination requires further evaluation.
