Action of aromatase inhibitor for treatment of uterine leiomyoma in perimenopausal patients

Objective: To assess the effect of the aromatase inhibitor on patients with leiomyoma in the reproductive stage regarding reduction of uterine volume and control of symptoms. Design: Clinical study. Setting: Academic clinical practice. Patient(s): Twenty patients, over 35 years of age, with symptomatic uterine leiomyoma. Intervention(s): Anastrozol, 1 mg/day for 12 weeks. Main Outcome Measure(s): Measurement of uterine volume, assessment of symptoms related to uterine leiomyoma, serum assay of follicle stimulating hormone (FSH), and estradiol. Results: Average reduction of uterine volume of 9.32%, attaining up to 32%, and reduction of symptoms of uterine leiomyoma (menstrual volume, duration of menstruation, and dysmenorrhea). No significant change in serum levels of FSH and estradiol during use of the medication were observed. Conclusion(S): Anastrozol proved to be effective in reducing the volume of the uterus-leiomyoma structure, leading to the control of symptoms connected with the disorder without changes in serum FSH and estradiol.

Surgical Treatment of Myelomeningocele Carried Out at `Time Zero` Immediately after Birth

Background/Aims: To present a protocol of immediate surgical repair of myelomeningocele (MMC) after birth (`time zero`) and compare this surgical outcome with the surgery performed after the newborn`s admission to the nursery before the operation. Methods: Data from the medical files of 31 patients with MMC that underwent surgery after birth and after admission at the nursery ( group I) were compared with a group of 23 patients with MMC admitted and prospectively followed, who underwent surgery immediately after birth - `at time zero` ( group II). Results: The preoperative rupture of the MMC occurred more frequently in group I (67 vs. 39%, p < 0.05). The need for ventriculoperitoneal shunt was 84% in group I and 65% in group II and 4 of them were performed during the same anesthetic time as the immediate MMC repair, with no statistically significant difference. Group I had a higher incidence of small dehiscences when compared to group II ( 29 vs. 13%, p < 0.05); however, there was no statistically significant difference regarding infections. After 1 year of follow-up, 61% of group I showed neurodevelopmental delay, whereas only 35% of group II showed it. Conclusions: The surgical intervention carried out immediately after the birth showed benefits regarding a lower incidence of preoperative rupture of the MMC, postoperative dehiscences and lower incidence of neurodevelopmental delay 1 year after birth.

Increased EMG response following electromyographic biofeedback treatment of rectus femoris muscle after spinal cord injury

Objective To study increases in electromyographic (EMG) response from the right and left rectus femoris muscles of individuals with long-term cervical spinal cord injuries after EMG biofeedback treatment. Design Repeated measure trials compared EMG responses before and after biofeedback treatment in patients with spinal cord injuries. Main outcome measures The Neuroeducator was used to analyse and provide feedback of the EMG signal and to measure EMG response. Setting Department of Traumatic Orthopaedics, School of Medicine, University of Sao Paulo, Brazil. Participants Twenty subjects (three men and 17 women), between 21 and 49 years of age, with incomplete spinal cord injury at level C6 or higher (range C2 to C6). Of these subjects, 10 received their spinal cord injuries from motor vehicle accidents, one from a gunshot, five from diving, three from falls and one from spinal disc herniation. Results Significant differences were found in the EMG response of the right rectus femoris muscle between pre-initial (T1), post-initial (T2) and additional (T3) biofeedback treatment with the subjects in a sitting position [mean (standard deviation) T1: 26 mu V (29); T2: 67 mu V (50); T3: 77 mu V (62)]. The mean differences and 95% confidence intervals for these comparisons were as follows: T1 to T2, -40.7 (-53.1 to -29.4); T2 to T3, -9.6 (-26.1 to 2.3). Similar differences were found for the left leg in a sitting position and for both legs in the sit-to-stand condition. Conclusions The EMG responses obtained in this study showed that treatment involving EMG biofeedback significantly increased voluntary EMG responses from right and left rectus femoris muscles in individuals with spinal cord injuries.

Stem cells in the treatment of chronic spinal cord injury: evaluation of somatosensitive evoked potentials in 39 patients

Study design: A prospective, non-randomized clinical series trial. Objective: To evaluate the effect of autogenous undifferentiated stem cell infusion for the treatment of patients with chronic spinal cord injury (SCI) on somatosensory evoked potentials (SSEPs). Setting: A public tertiary hospital in Sao Paulo, Brazil. Methods: Thirty-nine consecutive patients with diagnosed complete cervical and thoracic SCI for at least 2 years and with no cortical response in the SSEP study of the lower limbs were included in the trial. The trial patients underwent peripheral blood stem cell mobilization and collection. The stem cell concentrate was cryopreserved and reinfused through arteriography into the donor patient. The patients were followed up for 2.5 years and submitted to SSEP studies to evaluate the improvement in SSEPs after undifferentiated cell infusion. Results: Twenty-six (66.7%) patients showed recovery of somatosensory evoked response to peripheral stimuli after 2.5 years of follow-up. Conclusion: The 2.5-year trial protocol proved to be safe and improved SSEPs in patients with complete SCI. Sponsorship: None.

Early diagnostic and endoscopic dilatation for the treatment of acquired upper airway stenosis after intubation in children

Background: Upper airway stenosis (UAS) after endotracheal intubation is a common problem in children. Most literature refers to a surgical treatment for these lesions. Laryngotracheal reconstruction and cricotracheal resection are used for low- and high-grade stenosis, but decannulation is not always possible immediately after surgery. Purpose: The aim of this study was to verify the feasibility and results of endoscopic dilatations for treatment of subglottic stenosis. Method: The study encompassed a 12-year retrospective analysis of patients treated for UAS in a tertiary center. All children were symptomatic at the time of the endoscopic diagnosis. The stenosis was graded according to the Myer-Cotton criteria. Endoscopic dilatation was initiated immediately after the diagnosis. Children with grade IV stenosis underwent surgery. Results: Children with tracheal stenosis and no involvement of the subglottic area did not respond to endoscopic dilatations and underwent surgery. There were 45 children with grade I stenosis, 12 with grade II, 7 with grade III, and 4 with grade IV lesions. Patients with grade I, II, and III stenosis were a] I treated by endoscopic dilatations alone and were decannulated when asymptomatic. The average time for decannulation was 18.90 +/- 26.07 months for grade 1, 32.5 +/- 27.08 months for grade 11, and 27.57 +/- 20.60 months for grade III stenosis (P < .01, for grade II vs grade III). Conclusion: Grade I, II, and III subglottic stenoses can be safely managed by early endoscopic dilatations with a high rate of success and low rate of morbidity but require a significantly long period of treatment.

International Society for Sexual Medicine`s Guidelines for the Diagnosis and Treatment of Premature Ejaculation

Introduction. Over the past 20 years our knowledge of premature ejaculation (PE) has significantly advanced. Specifically, we have witnessed substantial progress in understanding the physiology of ejaculation, clarifying the real prevalence of PE in population-based studies, reconceptualizing the definition and diagnostic criterion of the disorder, assessing the psychosocial impact on patients and partners, designing validated diagnostic and outcome measures, proposing new pharmacologic strategies and examining the efficacy, safety and satisfaction of these new and established therapies. Given the abundance of high level research it seemed like an opportune time for the International Society for Sexual Medicine (ISSM) to promulgate an evidenced-based, comprehensive and practical set of clinical guidelines for the diagnosis and treatment of PE. Aim. Develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of PE for family practice clinicians as well as sexual medicine experts. Method. Review of the literature. Results. This article contains the report of the ISSM PE Guidelines Committee. It affirms the ISSM definition of PE and suggests that the prevalence is considerably lower than previously thought. Evidence-based data regarding biological and psychological etiology of PE are presented, as is population-based statistics on normal ejaculatory latency. Brief assessment procedures are delineated and validated diagnostic and treatment questionnaires are reviewed. Finally, the best practices treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with PE, in facilitating treatment of their patients. Conclusion. Development of guidelines is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to a more complete understanding of the pathophysiology as well as new efficacious and safe treatments for this sexual dysfunction. Therefore, it is strongly recommended that these guidelines be re-evaluated and updated by the ISSM every 4 years.

Body Mass Index Increase, Serum Leptin, Adiponectin, Neuropeptide Y and Lipid Levels during Treatment with Olanzapine and Haloperidol

Introduction: Body mass index (BMI) increase is an undesired effect associated with antipsychotics, and crucial for patients` global health and treatment compliance. We aimed to investigate the relation between BMI during olanzapine or halopericlol treatments and leptin, neuropeptide Y (NPY), adiponectin and lipid serum levels. Methods: In this 9-month, randomized and naturalist study, 34 male patients, 18 on olanzapine and 16 on haloperidol group were enrolled, all were under monotherapy. Patient outcome was evaluated with positive and negative syndrome scale (PANSS) at every 3-month period. In each visit, BMI, leptin, NPY, lipid, olanzapine or haloperidol levels were also monitored. Results and Discussion: Leptin levels positively correlated with BMI in olanzapine (r = 0.64, p < 0.001) and haloperidol (r = 0.73, p < 0.001) groups; only in olanzapine patients, the former also correlated with PANSS score (r = 0.54, p < 0.05). NPY levels negatively correlated with olanzapine levels (r = -0.65, p < 0.01). Adiponectin levels had not significantly varied. Conclusion: Antipsychotics probably interfere on leptin and NPY signalling ways and disturb these hormones in eating behaviour control.

Muscle sympathetic nervous activity in depressed patients before and after treatment with sertraline

Background Sympathetic hyperactivity is one of the mechanisms involved in the increased cardiovascular risk associated with depression, and there is evidence that antidepressants decrease sympathetic activity. Objectives We tested the following two hypotheses: patients with major depressive disorder with high scores of depressive symptoms (HMDD) have augmented muscle sympathetic nervous system activity (MSNA) at rest and during mental stress compared with patients with major depressive disorder with low scores of depressive symptoms (LMDD) and controls; sertraline decreases MSNA in depressed patients. Methods Ten HMDD, nine LMDD and 11 body weight-matched controls were studied. MSNA was directly measured from the peroneal nerve using microneurography for 3 min at rest and 4 min during the Stroop color word test. For the LMDD and HMDD groups, the tests were repeated after treatment with sertraline (103.3 +/- 40 mg). Results Resting MSNA was significantly higher in the HMDD [29.1 bursts/min (SE 2.9)] compared with LMDD [19.9 (1.6)] and controls [22.2 (2.0)] groups (P=0.026 and 0.046, respectively). There was a significant positive correlation between resting MSNA and severity of depression. MSNA increased significantly and similarly during stress in all the studied groups. Sertraline significantly decreased resting MSNA in the LMDD group and MSNA during mental stress in LMDD and HMDD groups. Sertraline significantly decreased resting heart rate and heart rate response to mental stress in the HMDD group. Conclusion Moderate-to-severe depression is associated with increased MSNA. Sertraline treatment reduces MSNA at rest and during mental challenge in depressed patients, which may have prognostic implications in this group.

Treatment of Resistant Obsessive-Compulsive Disorder With Ventral Capsular/Ventral Striatal Gamma Capsulotomy: A Pilot Prospective Study

A subgroup of obsessive-compulsive disorder (OCD) patients remains refractory to conventional treatments. For them, a new stereotactic radiosurgery has been recently developed: the ventral capsular/ventral striatal (VC/VS) gamma capsulotomy. The authors aim to report efficacy and adverse events of VC/VS gamma capsulotomy. Five refractory OCD patients were selected. The authors assessed OCD, anxiety and depressive symptoms, and side effects pre- and postoperatively. Three patients (60%) met response criteria 48 months after surgery. Adverse effects were episodic and transient. Ventral capsular/ventral striatal gamma capsulotomy holds therapeutic promise, with few adverse effects.

The role of alcoholic beverage preference in the severity of alcohol dependence and adherence to the treatment

The severity of dependence on alcohol and the efficacy of diverse types of treatments for alcoholism have been the subject of various researches. This study focused on the types of beverages preferentially consumed by alcohol-dependent outpatients and their effects on the severity of dependence and therapeutic outcomes. Our sample comprised 153 patients, 18-60 years of age, with an International Classification of Diseases (ICD-10) diagnosis of alcohol dependence, who were randomly divided into three different groups to receive topiramate (up to 300 mg/day), naltrexone (50 mg/day), or placebo during 12 weeks of follow-up. Spirits and beer were the main beverages consumed. At the start of this research, the group of spirits drinkers showed higher severity of alcohol dependence, higher craving for alcohol, more frequent history of treatments for alcoholism, and lower income than the group of beer preference drinkers. During the study, beer preference drinkers demonstrated higher adherence to the treatment, independently of the types of medications prescribed (P = .02, odds ratio, 2.46, 95% confidence interval, 1.17-5.19). This study suggests that the severity of dependence and the adherence to the treatment can be factors that set apart beer drinkers from spirits drinkers. As the compliance with the treatment for alcoholism was lower among spirits preference drinkers, a more intensive model of treatment would be necessary. (C) 2009 Elsevier Inc. All rights reserved.

Gamma ventral capsulotomy for treatment of resistant obsessive-compulsive disorder: A structural MRI pilot prospective study

Objective: The purpose of this study was to investigate regional structural abnormalities in the brains of five patients with refractory obsessive-compulsive disorder (OCD) submitted to gamma ventral capsulotomy. Methods: We acquired morphometric magnetic resonance imaging (MRI) data before and after 1 year of radiosurgery using a 1.5-T MRI scanner. Images were spatially normalized and segmented using optimized voxel-based morphometry (VBM) methods. Voxelwise statistical comparisons between pre- and post-surgery MRI scans were performed using a general linear model. Findings in regions predicted a priori to show volumetric changes (orbitofrontal cortex, anterior cingulate gyrus, basal ganglia and thalamus) were reported as significant if surpassing a statistical threshold of p<0.001 (uncorrected for multiple comparisons). Results: We detected a significant regional postoperative increase in gray matter volume in the right inferior frontal gyri (Brodmann area 47, BA47) when comparing all patients pre and postoperatively. Conclusions: Our results support the current theory of frontal-striatal-thalamic-cortical (FSTC) circuitry involvement in OCD pathogenesis. Gamma ventral capsulotomy is associated with neurobiological changes in the inferior orbitofrontal cortex in refractory OCD patients. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

Comparing topiramate with naltrexone in the treatment of alcohol dependence

To compare the efficacy of topiramate with naltrexone in the treatment of alcohol dependence. The investigation was a double-blind, placebo-controlled, 12-week study carried out at the University of Sao Paulo, Brazil. A total of 155 patients, 18-60 years of age, with an International Classification of Diseases (ICD-10) diagnosis of alcohol dependence. After a 1-week detoxification period, patients were assigned randomly to receive topiramate (induction to 300 mg/day), naltrexone (50 mg/day) or placebo. Time to first relapse (consumption of > 60 g ethyl alcohol), cumulative abstinence duration and weeks of heavy drinking. In intention-to-treat analyses, topiramate was statistically superior to placebo on a number of measures including time to first relapse (7.8 versus 5.0 weeks), cumulative abstinence duration (8.2 versus 5.6 weeks), weeks of heavy drinking (3.4 versus 5.9) and percentage of subjects abstinent at 4 weeks (67.3 versus 42.6) and 8 weeks (61.5 versus 31.5), but not 12 weeks (46.2 versus 27.8). Results remained significant after controlling for Alcoholics Anonymous attendance, which was higher in topiramate than in other groups. There were no significant differences between naltrexone versus placebo or naltrexone versus topiramate groups, but naltrexone showed trends toward inferior outcomes when compared to topiramate. The results of this study support the efficacy of topiramate in the relapse prevention of alcoholism. Suggestive evidence was also obtained for superiority of topiramate versus naltrexone, but this needs to be verified in future research with larger sample sizes.

Eosinophils in bronchial mucosa of asthmatics after allergen challenge: effect of anti-IgE treatment

Anti-IgE, omalizumab, inhibits the allergen response in patients with asthma. This has not been directly related to changes in inflammatory conditions. We hypothesized that anti-IgE exerts its effects by reducing airway inflammation. To that end, the effect of anti-IgE on allergen-induced inflammation in bronchial biopsies in 25 patients with asthma was investigated in a randomized, double-blind, placebo-controlled study. Allergen challenge followed by a bronchoscopy at 24 h was performed at baseline and after 12 weeks of treatment with anti-IgE or placebo. Provocative concentration that causes a 20% fall in forced expiratory volume in 1 s (PC(20)) methacholine and induced sputum was performed at baseline, 8 and 12 weeks of treatment. Changes in the early and late responses to allergen, PC(20), inflammatory cells in biopsies and sputum were assessed. Both the early and late asthmatic responses were suppressed to 15.3% and 4.7% following anti-IgE treatment as compared with placebo (P < 0.002). This was paralleled by a decrease in eosinophil counts in sputum (4-0.5%) and postallergen biopsies (15-2 cells/0.1 mm(2)) (P < 0.03). Furthermore, biopsy IgE+ cells were significantly reduced between both the groups, whereas high-affinity IgE receptor and CD4+ cells were decreased within the anti-IgE group. There were no significant differences for PC(20) methacholine. The response to inhaled allergen in asthma is diminished by anti-IgE, which in bronchial mucosa is paralleled by a reduction in eosinophils and a decline in IgE-bearing cells postallergen without changing PC(20) methacholine. This suggests that the benefits of anti-IgE in asthma may be explained by a decrease in eosinophilic inflammation and IgE-bearing cells.

A randomized controlled trial of acupuncture added to usual treatment for fibromyalgia

Objective: To evaluate the effectiveness of acupuncture for fibromyalgia. Methods: Fifty-eight women with fibromyalgia were allocated randomly to receive either acupuncture together with tricyclic antidepressants and exercise (n = 34), or tricyclic antidepressants and exercise only (n=24). Patients rated their pain on a visual analogue scale. A blinded assessor evaluated both the mean pressure pain threshold value over all 18 fibromyalgia points and quality of life using SF-36. Results: At the end of 20 sessions, patients who received acupuncture were significantly better than the control group in all measures of pain and in 5 of the SF-36 subscales. After 6 months, the acupuncture group was significantly better than the control group in numbers of tender points, mean pressure pain threshold at the 18 tender points and 3 subscales of SF-36. After one year, the acupuncture group showed significance in one subscale of the SF-36; at 2 years there were no significant differences in any outcome measures. Conclusion: Addition of acupuncture to usual treatments for fibromyalgia may be beneficial for pain and quality of life for 3 months after the end of treatment. Future research is needed to evaluate the specific effects of acupuncture for fibromyalgia.

Prevention and reversion of nonalcoholic steatohepatitis in ob/ob mice by S-nitroso-N-acetylcysteine treatment

Objective: To evaluate the role oral administration of S-nitroso-N-acetylcysteine (SNAC), a NO donor drug, in the prevention and reversion of NASH in two different animal models. Methods: NASH was induced in male ob/ob mice by methionine-choline deficient (MCD) and high-fat (H) diets. Two animal groups received or not SNAC orally for four weeks since the beginning of the treatment. Two other groups were submitted to MCD and H diets for 60 days receiving SNAC only from the 31(st) to the 60(th) day. Results: SNAC administration inhibited the development of NASH in all groups, leading to a marked decrease in macro and microvacuolar steatosis and in hepatic lipid peroxidation in the MCD group. SNAC treatment reversed the development of NASH in animals treated for 60 days with MCD or H diets, which received SNAC only from the 31(st) to the 60(th) day. Conclusions: Oral administration of SNAC markedly inhibited and reversed NASH induced by MCD and H diets in ob/ob mice.
