Endoscopic stapling diverticulotomy: an audit of difficulties, outcome, and patient satisfaction.

OBJECTIVE: To evaluate the procedure in terms of technical difficulties, patient satisfaction, symptom relief, recurrence, and further management. STUDY DESIGN: Retrospective study including 41 patients who underwent endoscopic stapling diverticulotomy. Clinical notes were reviewed, and patients were sent a patient satisfaction questionnaire. Statistical analysis was done using the chi(2) square test. SETTING: Teaching hospital. RESULTS: Larger pouches had the best results; 81.578% were satisfied with the surgery, and 86.84% had improved swallowing. Complications presented in 6 patients (15%), including a perforated pouch and an esophageal perforation. Complications were more frequent in small pouches. CONCLUSIONS AND SIGNIFICANCE: Endoscopic stapling diverticulotomy offers rapid recovery in most patients, with early oral intake and short hospital stay. There is a high degree of symptoms relief, and the patient's satisfaction rate is high. The assessment of the pharyngeal pouch size is an important factor when deciding the best management for a patient with a pharyngeal pouch.     

Needle necropsy in AIDS

The value of autopsy in understanding the natural course of any disease is beyond any argument. The reluctance of pathologists to perform autopsy in HIV infected cadavers is justified due to the risks involved to the prosector and the morgue attendants. A relative low risk needle necropsy protocol is proposed using fine needle aspiration cytology, tru-cut biopsies and microbiological examination. Diagnosis could be offered in all the forty-four needle necropsies performed. Disseminated tuberculosis in 18/44 (40.9%) cases, disseminated cryptococcosis in 12/44 (27.2%) cases, poly-microbial infections in 27.2% cases and non-Hodgkin's lymphoma in 9% cases were detected in the study. Infectious agents like Histoplasma capsulatum, Isospora belli, tachyzoites of Toxoplasma gondii, Candida sp and Cryptococcus sp could be demonstrated in the samples obtained in the study. Lack of material for study of gross pathology, inaccessibility of deep-seated lesions and risk of needle stick injury to the prosector though low are the limitations of this procedure.     

Biosocial aspects of domestic violence

Domestic violence, defined as acts of verbal abuse and physical violence performed against women by current intimate main partners, was surveyed by means of the Conflict Tactics Scale. We examined the relationships between a biological variable (testosterone level), social variables (demographics, social integration), and behaviour (substance use) and self-reported domestic violence. Forced-entry OLS regression models allowed us to study how social and behavioural variables modified the effects of testosterone on this specific violent behaviour.The sample consisted of 54 men who had a main sexual partner and who identified themselves as Black, White, or Hispanic. The men were recruited from various social-service-agency sites in the area of Miami, Florida, on the basis of their risk factors for HIV/AIDS. The sample can best be described as culturally diverse men of low socioeconomic status who had a main sexual partner. A high percentage of participants reported some level of both verbal and physical aggression towards their partners. Testosterone levels were significantly associated with levels of both verbal aggression and physical violence self-reported by the men. Testosterone level, demographic characteristics, and alcohol consumption contributed to explaining the variance in self-reported verbal and physical abuse. The high heritability of testosterone level and its association with violent behaviour warrant the inclusion of this variable in studies of antisocial and criminal behaviour including domestic violence.     

Temporomandibular disorder in a patient with pseudoxanthoma elasticum: a case report and review

Pseudoxanthoma elasticum (PXE) is a disorder characterized by progressive degeneration of elastic fibers and ectopic mineralization. Cutaneous manifestations are a hallmark of this disease and organs that may be affected by the disease process include cardiovascular, central nervous system, ocular and gastrointestinal systems. Oral manifestations of PXE have been previously reported as intramucosal nodules observed on various intraoral surfaces. We present a case of a 46‐year‐old female with PXE diagnosed with temporomandibular disorder (TMD). To our knowledge, this is the first report of a patient with TMD coexisting with PXE in the scientific literature.     

Point of Care Ultrasound: A WFUMB Position Paper

Over the last decade, the use of portable ultrasound scanners has enhanced the concept of point of care ultrasound (PoC-US), namely, “ultrasound performed at the bedside and interpreted directly by the treating clinician.” PoC-US is not a replacement for comprehensive ultrasound, but rather allows physicians immediate access to clinical imaging for rapid and direct solutions. PoC-US has already revolutionized everyday clinical practice, and it is believed that it will dramatically change how ultrasound is applied in daily practice. However, its use and teaching are different from continent to continent and from country to country. This World Federation for Ultrasound in Medicine and Biology position paper discusses the current status and future perspectives of PoC-US. Particular attention is given to the different uses of PoC-US and its clinical significance, including within emergency and critical care medicine, cardiology, anesthesiology, rheumatology, obstetrics, neonatology, gynecology, gastroenterology and many other applications. In the future, PoC-US will be more diverse than ever and be included in medical student training.     

Challenges in valve-in-valve therapy

At present, the majority of surgical heart valves (SHVs) implanted are bioprosthetic valves. Over time however, these are prone to structural deterioration, which may manifest as valvular stenosis, regurgitation or a combination of the two. Re-operation is the current standard of care for these patients but this itself carries a significant risk of mortality and morbidity. As a natural extension of transcatheter aortic valve implantation (TAVI), now an evidence based solution for severe aortic stenosis in high-risk patients, valve-in-valve (VIV) therapy is evolving into an alternative option in selected patients with structural biological valvular deterioration in all four-valve positions. The first of these VIV procedures was performed in Germany in 2007, for failing aortic valve prosthesis and later, reported in other positions. As with any novel emerging therapy, there is a learning curve to the procedure and the operator must be aware of the potential challenges. In this review we describe some of these challenges with the aim of providing awareness as well as guidance on attaining a successful outcome.
