Management of refractory ischemic priapism: current perspectives

The aim of the present manuscript is to review the current literature on priapism, focusing on the state-of-the-art knowledge of both the diagnosis and the treatment of the refractory ischemic priapism (IP).



Pubmed and EMBASE search engines were used to search for words "priapism", "refractory priapism", "penile prosthesis", "diagnosis priapism", "priapism treatment", "penile fibrosis", "priapism therapy". All the studies were carefully examined by the authors and then included in the review.



First-line treatment involves ejaculation, physical exercise and cold shower followed by corporal blood aspiration and injection of α-adrenoceptor agonists. Subsequently, a distal or proximal shunt may be considered. If none of the treatment is effective or the priapism episode lasts >48 hours penile prosthesis implantation could be the only option to solve the priapism and treat the ongoing erectile dysfunction.



The management of IP is to achieve detumescence of persistent penile erection and to preserve erectile function after resolution of the priapic episode. On the other hand, penile fibrosis and following shortening should be prevented. Early penile prosthesis implantation in patients with refractory IP is able to solve both the priapic episode and prevent the otherwise certain penile shortening. Penile prosthesis implantation is the actual gold standard of care in cases of refractory IP.
Culturally Grounded Substance Use Prevention: An Evaluation of the keepin' it R.E.A.L. Curriculum

This paper reports on the evaluation of a culturally grounded prevention intervention targeting substance use among urban middle-school students. The curriculum consists of 10 lessons promoting antidrug norms and teaching resistance and other social skills, reinforced by booster activities and a media campaign. Three versions were delivered: Mexican American, combined African American and European American, and Multicultural. Thirty-five middle schools were randomly assigned to 1 of the 3 versions or the control. Students completed baseline and follow-up questionnaires over a 2-year period (total 6,035 respondents). Analyses utilizing a generalized estimating equations approach assessed the overall effectiveness of cultural grounding and the cultural matching hypothesis. Support was found for the intervention's overall effectiveness, with statistically significant effects on gateway drug use as well as norms, attitudes, and resistance strategies but with little support for the cultural matching hypothesis. Specific contrasts found the Mexican American and Multicultural versions impacted the most outcomes.
Changes in quality of life in patients with breast cancer.

To describe and compare changes in quality of life in two groups of patients with breast cancer and to identify factors predicting negative changes in quality of life within six months.



Women with breast cancer suffer from various treatment side-effects, from psychological and social symptoms as well as decreased quality of life, creating a need for support that may persist throughout the breast cancer experience.



This six-month longitudinal study involved a sample of 164 women, who were quasi-randomized between intervention (n = 85) and control groups (n = 79) after breast cancer surgery. Intervention group received support and education via telephone one week after the breast cancer surgery and face-to-face support six months after the surgery. Quality of life was estimated one week and six months after breast cancer surgery, using the Quality of Life Index-Cancer Version (QLI-CV) and the European Organisation for Research and Treatment of Cancer Breast Cancer-Specific Quality of Life questionnaire (EORTC QLQ-BR23).



Data were analysed statistically using descriptive statistics and non-parametric tests. Factors predicting negative changes in quality of life within six months were investigated using logistic regression models with the enter method.



Significant group difference in the magnitude of changes within six months was found in future outlook. Logistic regression analyses revealed six significant predictors of negative changes in quality of life within six months: education, employment status, having underaged children, chemotherapy, radiotherapy and hormonal therapy.



The results of this study underline the importance of identifying quality of life changes in patients with breast cancer and paying attention to those women with difficulties in adapting to being a cancer survivor.


 TO CLINICAL PRACTICE
The findings of this study provide evidence which may help to create appropriate supportive interventions for both acute and long-term settings.
Completion of mitral isthmus ablation using a steerable sheath: prospective randomized comparison with a nonsteerable sheath.

Although mitral isthmus (MI) ablation in atrial fibrillation (AF) patients has been shown to be an effective ablative strategy, the establishment of the bidirectional conduction block of the MI is technically challenging. We investigated the usefulness of a steerable sheath for MI ablation in patients with persistent AF and its impact on the clinical outcome of persistent AF ablation.



A total of 80 consecutive patients undergoing MI ablation were randomized to 1 of the following 2 groups: group S (using a steerable long sheath) or group NS (using a nonsteerable long sheath). MI ablation was performed by using an open-irrigated ablation catheter with the guidance of a 3-dimensional mapping system. The endpoint of the MI ablation was the achievement of a bidirectional block.



Bidirectional block through the MI was achieved in 87.5% (70/80) of patients with 14.0 ± 6.7 minutes of radiofrequency application. The bidirectional block was more frequently achieved in patients in group S compared to group NS (97.5% (39/40) vs 77.5% (31/40), P = 0.02). Additionally, epicardial ablation within the coronary sinus was less frequently required in group S compared to group NS (12.5% (5/40) vs 72.5% (29/40), P < 0.0001). Atrial tachycardia after the procedure more frequently occurred in the patients in whom MI block had not been achieved during the initial procedure (40.0% (4/10) vs 10.0% (7/70), P = 0.04).



The MI block could be achieved in the majority of patients by using a steerable sheath. An incomplete MI block increased the risk of AT following persistent AF ablation.
Study protocol for a randomized controlled trial: the feasibility and impact of cardiovascular absolute risk assessment in Australian general practice.

Although cardiovascular absolute risk (CVAR) assessment has been recommended for use in Australian general practice for a number of years, there is continuing uncertainty about its implementation and impact. Our previous work has developed a multifaceted implementation model. This study aims to investigate both the feasibility of using this model and the impact of CVAR assessment and management on general practice clinical processes and patient care.



This cluster randomized controlled trial will be conducted in general practices in Sydney, involving general practitioners (GPs), other practice staff, and patients aged 45 to 69 years without existing cardiovascular disease.



A total of 32 practices (40 GPs) and 1,320 patients will be recruited. Randomization will be conducted at the practice level. The intervention group of GPs will be trained to use a CVAR implementation model, whereas the control group of GPs will continue usual care. Study outcomes include clinical processes, patient risk, use of lifestyle intervention, and prescription of antihypertensive and lipid-lowering medications. Data will be collected and analyzed using mixed methods. Study outcomes before and after the intervention will be compared, and the 2 groups will also be compared after adjusting for baseline difference and clustering factors.



This trial will be the first study in Australian general practice and one of few international studies to evaluate the impact of implementing CVAR assessment and management. Results of this study will help improve the primary prevention of cardiovascular disease and inform guidelines for clinical practice and the implementation of other health initiatives.
Eighty-one percent event-free survival in advanced Burkitt's lymphoma/leukemia: no differences in outcome between pediatric and adult patients treated with the same intensive pediatric protocol.

Advanced Burkitt's lymphoma (BL) has an extremely poor prognosis in adults. With a previous protocol including CNS prophylaxis, 40% of our adult patients achieved CR and only 13% became long survivors. In 1988, following this poor experience, we adopted a very intensive pediatric-derived protocol.



Twenty-one consecutive patients, 8 adults (median age 35, stage III: 1; IV: 7; leukemias: 6) and 13 children (median age 10, state III: 8; IV: 5; leukemias: 4) were treated with the same protocol (POG 8617), based on alternate two-phase cycles with sequential high-dose CTX, VCR, ADM + CNS chemoprophylaxis (phase A) and HD MTX + HiDAC (phase B). Adults received 6 cycles, children 8; i.t. prophylaxis in phase B was omitted in adults.



Twenty of 21 (95%) patients achieved CR (adults 100%, children 92%). Two patients died early; 2 relapsed at 4 and 9 months. With a median follow-up of 28 months (4-96), 17 patients (81%) are event free (adults 75%, children 85%). Severe infections affected 62% of adults and 15% of children.



(1) The prognosis of adult advanced BL definitely improved with this intensive protocol. (2) There were no differences in outcome between adults and children. (3) Outcome of lymphoma and leukemia was similar. (4) Severe infections occurred frequently in adults. This intensive pediatric protocol requires a careful supportive therapy.
Conscious Sedation Procedures Using Intravenous Midazolam for Dental Care in Patients with Different Cognitive Profiles: A Prospective Study of Effectiveness and Safety

The use of midazolam for dental care in patients with intellectual disability is poorly documented. This study aimed to evaluate the effectiveness and safety of conscious sedation procedures using intravenous midazolam in adults and children with intellectual disability (ID) compared to dentally anxious patients (DA). Ninety-eight patients with ID and 44 patients with DA programmed for intravenous midazolam participated in the study over 187 and 133 sessions, respectively. Evaluation criteria were success of dental treatment, cooperation level (modified Venham scale), and occurrence of adverse effects. The mean intravenous dose administered was 8.8±4.9 mg and 9.8±4.1 mg in ID and DA sessions respectively (t-test, NS). 50% N₂O/O₂ was administered during cannulation in 51% of ID sessions and 61% of DA sessions (NS, Fisher exact test). Oral or rectal midazolam premedication was administered for cannulation in 31% of ID sessions and 3% of DA sessions (p<0,001, Fisher exact test). Dental treatment was successful in 9 out of 10 sessions for both groups. Minor adverse effects occurred in 16.6% and 6.8% of ID and DA sessions respectively (p = 0.01, Fisher exact test). Patients with ID were more often very disturbed during cannulation (25.4% ID vs. 3.9% DA sessions) and were less often relaxed after induction (58.9% ID vs. 90.3% DA) and during dental treatment (39.5% ID vs. 59.7% DA) (p<0.001, Fisher exact test) than patients with DA. When midazolam sedation was repeated, cooperation improved for both groups. Conscious sedation procedures using intravenous midazolam, with or without premedication and/or inhalation sedation (50% N₂O/O₂), were shown to be safe and effective in patients with intellectual disability when administered by dentists.
Scalable Thread Sharing Analysis

We present two scalable algorithms for identifying program locations that access thread-shared data in concurrent programs. The static algorithm, though simple, and without performing the expensive whole program information flow analysis, is much more efficient, less memory-demanding, and even more precise than the classical escape analysis algorithm. The dynamic algorithm, powered by a locationbased approach, achieves significant runtime speedups over a precise dynamic escape analysis. Our evaluation on a set of large real world complex multithreaded systems such as Apache Derby and Eclipse shows that our algorithms achieve unprecedented scalability. Used by client applications, our algorithms reduce the recording overhead of a record-replay system by 9X on average (as much as 16X) and increase the runtime logging speed of a data race detector by 32% on average (as much as 52%).
Albuterol Overuse: A Marker of Psychological Distress?

Albuterol overuse, 3 or more canisters per year, is associated with poor asthma control and frequent exacerbations.



To describe albuterol use on symptom and symptom-free days and identify predictors of albuterol overuse and controller medication underuse.



Secondary analyses of data from adults with mild asthma from the Trial of Asthma Patient Education were carried out. Based on albuterol use of 80% or more on symptom days and less than 20% on symptom-free days, participants were characterized as expected users, overusers, or underusers of albuterol. Good controller medication adherence was defined as 80% or more of prescribed doses. Data included demographic characteristics, diary data, spirometry, and scores from standardized questionnaires. Bivariate associations were examined between categorization of medication use and measured characteristics.



Of the 416 participants, 212 (51%) were expected users, 114 (27%) were overusers, and 90 (22%) were underusers of albuterol. No differences were observed among the user groups by demographic characteristics or lung function. Expected users demonstrated the highest asthma-related knowledge, attitudes, and efficacy. Overusers reported the greatest symptom burden, worst asthma control, and highest frequency of symptom days. Overusers also had the highest burden of depression symptoms. More frequent symptom days accounted for 15% of overuse, greater use on symptom days accounted for 31%, and greater use on symptom free days accounted for 54% of overuse. Mean controller adherence was high across all groups, and there were no differences between the groups.



Although overusers experienced more frequent symptom days and used more albuterol on those days, most overuse was attributable to unexpected use on symptom-free days. High levels of comorbid depression were observed, particularly among overusers and among those nonadherent to controller medication.
Preventing amikacin related ototoxicity with N-acetylcysteine in patients undergoing peritoneal dialysis

Amikacin is a frequently used antibiotic in the treatment of peritoneal dialysis (PD)-related peritonitis. Ototoxicity is a well-known complication of amikacin for which increased oxidative stress and free oxygen radicals are thought to be responsible. In this study, the effect of N-acetyl-cysteine (NAC) on cochlear function and oxidant situation in the amikacin related ototoxicity in PD-related peritonitis patients are investigated. Forty-six patients who had their first PD-related peritonitis attacks receiving empirical amikacin treatment were enrolled in the study. The patients were randomized into two groups; the first group (n = 23) as NAC receiving and the second group (n = 23) as a placebo receiving, control group. Otoacoustic emissions were measured before, 1 week after and 4 weeks after the treatment. Oxidative stress measurements were performed concurrently in order to evaluate the effectiveness of NAC. The results of screening with otoacoustic emission testing after amikacin treatment showed that cochlear function is protected especially in higher frequencies in NAC group when compared with the control group. Evaluation of the antioxidant status of the two groups showed no differences in the basal values, but at the first week there was an increase in the NAC group compared with the control group, and this increase became significant at the fourth week. NAC is found to be safe and effective in amikacin-related ototoxicity in patients with PD-related peritonitis. We suggest a close monitoring of the patients receiving amikacin containing treatment protocols and if amikacin is administrated supplementing the treatment with NAC.
Analysis of number needed to treat for droxidopa in patients with symptomatic neurogenic orthostatic hypotension

Droxidopa is an orally active prodrug that significantly improved dizziness/lightheadedness measured using the Orthostatic Hypotension Symptom Assessment (OHSA) Item 1 in patients with neurogenic orthostatic hypotension (nOH) caused by primary autonomic failure (Parkinson disease, multiple system atrophy, and pure autonomic failure), dopamine β-hydroxylase deficiency, or nondiabetic autonomic neuropathy. The efficacy and safety of droxidopa were assessed by determining the number needed to treat (NNT) and the number needed to harm (NNH).



Data collected in randomized, placebo-controlled clinical studies in adults with a clinical diagnosis of symptomatic nOH were pooled for efficacy and safety analyses. NNT and NNH were calculated as reciprocals of the risk difference (difference in event rates) for droxidopa versus placebo.



The NNT for droxidopa for improvement in OHSA Item 1 was <10. The NNH for adverse events (AEs) leading to discontinuation in the pooled studies was 81. The likelihood of being helped or harmed (LHH) calculated from pooled analysis of the NNT for ≥2 units of improvement in OHSA Item 1 score and the NNH for discontinuations due to AEs were 7.8, 8.8, 3.1, and 3.5 for weeks 1, 2, 4, and 8 after randomization, respectively.



Droxidopa is efficacious for treatment of nOH, with an NNT below 10 and an acceptable tolerability profile with NNH ranging from 23 to 302 in the pooled analysis of frequently occurring AEs. Based on the LHH for the pooled analysis at week 1, droxidopa is 7.8 times more likely than placebo to show a clinical benefit than result in discontinuation because of an AE.

Identification of genetic variants in TNF receptor 2 which are associated with the development of cervical carcinoma.

Cervical cancer is one of the most common malignancies among women in India. Beside HPV, other factors present in host also put their role in the progression of cervical tumerogenesis. In present study, we screened 300 subjects to identify variations in TNFR2 gene by PCR-dHPLC method followed by direct sequencing. We identified six known and four novel variations in six different exons of TNFR2 gene. Out of these identified variations, five known variations were found to be significantly associated with the risk of cervical cancer (p < 0.0001). On construction of haplotypes, one haplotype (TTGCC) was emerged as a major protective type while two (CAAGC + CTGCC) were revealed as major risk haplotypes. In conclusion, postmenopausal women having CAAGC + CTGCC haplotypes in TNFR2 gene along with HPV infection and tobacco consumption may lead to the development of cervical cancer.
Adjuvant therapy for melanoma in dogs: results of randomized clinical trials using surgery, liposome-encapsulated muramyl tripeptide, and granulocyte macrophage colony-stimulating factor.

Spontaneous canine oral melanoma (COM) is a highly metastatic cancer, resistant to chemotherapy, and can serve as a model for cancer immunotherapy. Liposome-encapsulated muramyl tripeptide-phosphatidylethanolamine (L-MTP-PE) can activate the tumoricidal activity of the monocyte-macrophage system following i.v. injection. The objective of these studies was to evaluate the therapeutic effectiveness of L-MTP-PE administered alone and combined with recombinant canine granulocyte macrophage colony-stimulating factor (rcGM-CSF) in dogs undergoing surgery for oral melanoma. Ninety-eight dogs with histologically confirmed, clinically staged, oral melanoma were entered into two randomized, double-blind, surgical adjuvant trials. In trial 1, 50 dogs were stratified based on clinical stage and randomized to once a week L-MTP-PE or lipid equivalent (control). When all of the clinical stages were combined, no difference in disease-free survival or in survival time (ST) were detected. However, within stage I, dogs receiving L-MTP-PE had a significant increase in ST compared with control, with 80% of the dogs treated with L-MTP-PE still alive at >2 years. Within each stage II and stage III, there was no difference detected between the treatment groups. In trial 2, 48 dogs were stratified on the basis of clinical stage and extent of surgery (simple resection or radical excision), treated with L-MTP-PE two times a week, and randomized to rcGM-CSF or saline (placebo) given s.c. daily for 9 weeks. Within each stage and when all of the stages were combined, there was no difference between the treatment groups. In both studies, stage I COM is associated with a better prognosis. No effect on survival was observed with regard to tumor location in the oral cavity, sex, type/extent of surgery, or age. In a subset of dogs tested, pulmonary alveolar macrophage cytotoxicity was enhanced with combined rcGM-CSF and L-MTP-PE but not in dogs treated with L-MTP-PE alone. The present study indicates that after surgery, L-MTP-PE administered alone or combined with rcGM-CSF showed no significant antitumor activity in treating advanced stage COM. In early stage COM, L-MTP-PE was shown to result in a prolongation of ST. Furthermore, this study provides additional rationale for the use of the dog model for human malignant melanoma.
Sexual functioning, quality of life and pelvic pain 12 months after endometriosis surgery including vaginal resection.

To evaluate sexual function, quality of life and pelvic pain after endometriosis surgery including vaginal resection.



Prospective observational study with 12 months follow up.



Regional central hospital and university hospital.



Twenty-two patients with deep endometriotic nodules in the posterior fornix of the vagina undergoing complete excision of endometriosis, including vaginal resection.



Sexual functioning was measured with the McCoy Female Sexuality Questionnaire, quality of life with a generic questionnaire (15D) and pain with a 10-point visual analog scale. Questionnaires were completed before and 12 months after the surgery.  Changes in sexual function scores, quality-of-life scores and pain.



Twelve months after surgery, the sexual satisfaction score was higher (p= 0.03) and the sexual problems score lower (p= 0.04) compared with baseline values. Health-related quality-of-life scores for discomfort and symptoms (p= 0.001), distress (p= 0.04), vitality (p= 0.03) and sexual activity (p= 0.001), and the overall 15D score (p < 0.001), were significantly improved. The severity of all studied types of pain was significantly decreased (p < 0.05).



Complete excision of endometriosis, including vaginal resection, seems to offer a significant improvement in sexual functioning, quality of life and pelvic pain in symptomatic patients with deeply infiltrating endometriotic nodules in the posterior fornix of the vagina. This surgery may be associated with complications and adverse new-onset symptoms, and should be performed only after thorough consultation with the patient.
