RESUMO
Luminal distensibility measurement has demonstrated relevance to various disease processes, though its effects on clinical decision-making have been less well understood. This study aims to characterize the clinical impact of impedance planimetry measurement as well as the learning curve associated with its use in the esophagus. A single provider performed distensibility measurement in conjunction with upper endoscopy for a variety of clinical indications with the functional lumen imaging probe (FLIP) over a period of 21 months. Procedural data were prospectively collected and, along with medical records, retrospectively reviewed. Seventy-three procedures (70 patients) underwent esophageal distensibility measurement over the timeline of this study. The most common procedural indications were known or suspected achalasia (32.9%), dysphagia with connective tissue disease (13.7%), eosinophilic esophagitis (12.3%), and dysphagia with prior fundoplication (9.6%). FLIP results independently led to a change in management in 29 (39.7%) cases and supported a change in management in an additional 15 (20.5%) cases. The most common change in management was a new or amended therapeutic procedure (79.5%). Procedural time added by distensibility measurement was greater among earlier cases than among later cases. The median time added overall was 5 minutes and 46 seconds. Procedural time added varied significantly by procedural indication, but changes in management did not. Distensibility measurement added meaningful diagnostic information that impacted therapeutic decision-making in the majority of cases in which it was performed. Procedural time added by this modality is typically modest and decreases with experience.

BACKGROUND: Esophagogastric junction (EGJ) outflow obstruction (EGJOO) is characterized by impaired EGJ relaxation with intact or weak peristalsis. Our aims were to evaluate: (i) prevalence, (ii) yield of fluoroscopy, endoscopy, and endoscopic ultrasound (EUS), (iii) outcomes, and (iv) whether this data differed based on quantitative EGJ relaxation. METHODS: Studies that met criteria for EGJOO were identified. Demographics, encounters, endoscopy, radiology, treatment decisions, and outcomes were extracted. KEY RESULTS: Sixty studies were identified. Dysphagia was the most common symptom. Forty patients underwent barium esophagram (BE): normal (11), hiatal hernia (20), spasm/dysmotility (17), EGJ narrowing (10), compression (2), Schatzki's ring (5), malrotation (1), gastric volvulus (1), mass (1). Esophagogastroduodenoscopy (EGD) was performed in 41 patients: normal (19), hiatal hernia (13), Schatzki's ring (6), esophagitis (3), esophageal candidiasis (3), mass (1). EUS was performed in 20 patients and was frequently normal. Twenty-two patients underwent intervention. While transient improvement was noted in the majority, persistent improvement was seen in only one of nine patients (dilatation), four of six patients (botulinum toxin), and three patients who underwent per-oral endoscopic myotomy. No patients treated with medical therapy alone had improvement in dysphagia. There was no difference in symptoms or outcomes based on quantitative EGJ relaxation. CONCLUSIONS & INFERENCES: The manometric criterion EGJOO defines a heterogeneous clinical group. While BE, EGD, and EUS all provide complementary information, a significant percentage of these studies will be normal. For patients with dysphagia, outcome may depend on EGJ disruption. There were no differences in symptoms our outcomes based on quantitative EGJ relaxation.

Eosinophilic esophagitis (EoE) is a chronic, immune-mediated disease resulting in symptoms of esophageal dysmotility. Abnormalities include dysphagia, food impaction and reflux. Although men appear to comprise a majority of the EoE population, few studies have directly assessed gender-associated clinical differences. The aim of this study is to identify the effect of gender on the initial clinical presentation of adult-onset EoE patients. We reviewed our electronic medical record database from January 2008 to December 2011 for adults diagnosed with EoE per the 2011 updated consensus guidelines. Patient demographics, presenting symptoms, endoscopy findings and complications were recorded. Proportions were compared using chi-squared analysis, and means were compared using the Student's t-test. A total of 162 patients met the inclusion criteria and 71 (44%) were women. Women were more likely to report chest pain (P = 0.03) and heartburn (P = 0.06), whereas men more commonly reported dysphagia (P = 0.04) and a history of food impaction (P = 0.05). Endoscopic findings were similar between groups. No patients suffered esophageal perforations. These data suggest that men report more fibrostenotic symptoms and women report more inflammatory symptoms at the time of diagnosis. There was no difference in endoscopic findings between genders. This is one of the only reviews comparing differences in clinical presentation, endoscopic findings and complications between gender for EoE. The current recommended guidelines state that any patient with symptoms of esophageal dysfunction should be biopsied for EoE. Our findings support biopsying patients with typical and atypical symptoms of dysmotility including heartburn and chest pain.

BACKGROUND: Eosinophilic oesophagitis (EoE) is a growing cause of dysphagia. Current therapies include dietary manipulation, steroids and biological drugs. AIM: To perform a systematic review and summarise the effect of different medical interventions on EoE. METHODS: Two reviewers searched Pubmed and Embase for studies on treatment for EoE. We included randomised controlled trials (RCT) limited to pharmacological interventions. Two reviewers selected studies. Meta-analysis was done using random effects model to estimate odds ratio (OR). Heterogeneity was determined by Cochran's Q statistic and I(2) . RESULTS: Seventeen references met our inclusion criteria. Eleven RCTs involving 455 participants were included in the meta-analysis. 325 participants were evaluated for symptomatic improvement and 330 were evaluated for histological remission. Symptomatic improvement with topical steroids (7 studies, 250 participants) compared to the control group (placebo or PPI) was noted (OR: 3.03, 95% confidence interval, CI: 1.57-5.87). Histological remission was also noted in nine studies involving 330 participants (OR: 13.66, 95% CI: 2.65-70.34) comparing topical steroids to a control (placebo or PPI). There was no difference between anti-IL-5 drugs and placebo in terms of symptomatic improvement (OR: 0.69, 95% CI: 0.34-1.42). CONCLUSIONS: Topical steroids induce significant symptomatic and histological remission, and should be considered as a first line treatment. Anti-IL-5 therapy has a minor effect on eosinophilic oesophagitis. Future research in eosinophilic oesophagitis should standardise methodology according to published guidelines to improve quality and allow direct comparison between therapies.

HIV vaccine development remains an urgent priority. Vaccine preparedness studies to assess feasibility are an important precursor to HIV vaccine trials. Studies such as these have taken place in many non-Organization for Economic Co-operation and Development (non-OECD) countries using diverse cohorts. This article is a systematic review of retention rates and willingness to participate (WTP) in HIV vaccine trials. Studies took place in Brazil, the Democratic Republic of Congo, Haiti, India, Russia, Thailand, and several sub-Saharan African countries. Studies generally reported recruitment of high-risk individuals. Of 33 studies we identified, retention was assessed in 16 studies, and the 12-month retention ranged from 77 to 85%. Willingness to participate was assessed in 21 studies. Willingness to participate ranged from 23 to 100%, and increased knowledge was associated with an increased WTP. Vaccine preparedness studies have taken place using diverse cohorts in the non-OECD countries. In general, retention rates and WTP have been adequate to conduct HIV vaccine trials. Educational programs to improve knowledge about HIV vaccines may contribute to better follow-up and an increased WTP in these countries.

HIV vaccine development remains an urgent priority. This article is a systematic review of HIV vaccine preparedness studies in the high-income 30 Organization for Economic Co-operation and Development countries, to identify factors important for HIV vaccine trial development in injection drug users (IDU), men who have sex with men (MSM), and women at heterosexual risk (WAHR) across these countries. Of 27 articles we identified, willingness to participate (WTP) was assessed in eight studies involving IDU, 11 involving MSM, and one involving WAHR. WTP ranged in IDU at 41-86%, MSM at 23-94%, and in WAHR, it was at 81%. Studies reported recruitment of high-risk individuals. Retention was assessed in eight studies involving IDU, five involving MSM, and three involving WAHR. IDU were retained at a range of 3-98%, MSM at 70-95% and WAHR at 67-92%. This review provides an in-depth summary of HIV vaccine preparedness studies that were conducted in the Organization for Economic Co-operation and Development countries.

BACKGROUND: Gastrointestinal endoscopy is an integral tool in the evaluation and management of many gastrointestinal and hepatobiliary conditions. Although rare, media reports of infectious complications following gastrointestinal endoscopy persist in this new millennium. With only limited data available, society guidelines continue to suggest that endoscopes undergo a reprocessing cycle before the first patient of the day. This preliminary study aimed to assess the microbiological stability of gastrointestinal endoscopes after high-level disinfection. METHODS: In this multiphase study, four endoscopic retrograde cholangiopancreatography (ERCP) scopes and three colonoscopes were evaluated. In phase 1, endoscopes were assayed after initial high-level disinfection and daily for a period of 2 weeks. In phase 2, this procedure was repeated to confirm phase 1 results. In phase 3, endoscopes were assayed after high-level disinfection and again following a 7-day storage period. RESULTS: In phase 1, 6 of 70 (8.6 %) assays were positive. This involved 4 of 7 (57 %) endoscopes (2 colonoscopes and 2 ERCP scopes) and was limited to the first 5 days of the study. No cultures were positive in phase 2. In phase 3, one endoscope had a positive culture. Positive cultures grew only STAPHYLOCOCCUS EPIDERMIDIS, a low-virulence skin organism. DISCUSSION: With proper disinfection and storage, it appears that reprocessing of gastrointestinal endoscopes is unnecessary after periods of disuse of at least 7 days and possibly up to 2 weeks. Despite recent media reports of infectious complications, society guidelines that recommend more frequent reprocessing seem to lack scientific merit and need to be revisited.

Hemorrhage is the major cause of death in pelvic fractures. In closed pelvic fractures the bleeding is usually self-limited. In the small number of patients with continuing hemorrhage there may be disruption of a major iliac vessel, which will require immediate exploration and repair. In a few patients continuing hemorrhage is due to disruption of a branch of the hypogastric artery, which may be identified by angiography and controlled by embolization. A management protocol is suggested for these patients.

We describe a case of congenital ependymoblastoma presenting as a subcutaneous mass in the sacrococcygeal area of a newborn male. The tumor was composed of primitive cells disposed in compact sheets and cords and exhibiting focal ependymal differentiation. No other line of cellular differentiation was identified by either immunohistochemistry or ultrastructural study. Elevated serum alpha-fetoprotein was found, which decreased following surgical extirpation of the tumor. We propose that this tumor had its origin in the ependymal medullary vestige, similar to other sacrococcygeal ependymomas.
