Hydatid disease presenting as an intrascrotal mass in a child.

A thirteen-year-old boy with the preliminary diagnosis of hydrocele of the cord who underwent surgery is presented. Ultimate diagnosis of hydatid disease was established by surgical exploration and histopathologic examination of the specimen. Although it is a rare occurrence, hydatid disease should be considered as a diagnostic possibility in endemic areas.

Vaginal atresia and Bardet-Biedl syndrome association: a component or a distinct entity?

Bardet-Biedl syndrome is an autosomal recessive disorder. It is characterized by cardinal anomalies including retinal dystrophy, digital malformations, mental retardation, obesity, and hypogonadism. Recently, renal anomalies also are mentioned among the cardinal signs. Although association of genital anomalies among affected boys are well known, the association of vaginal atresia and other structural genital anomalies are not mentioned among the less-common manifestations of Bardet-Biedl syndrome in girls. Two girls with Bardet-Biedl syndrome presented with hematometrocolpos in the preadolescent period and vaginal atresia was diagnosed. After surgical treatment and extended hospitalization, uncontrolled sepsis resulted in progressive renal failure and death of both patients. Vaginal atresia is often delayed or missed in the early childhood period. In girls with Bardet-Biedl syndrome, vaginal atresia or other structural genital anomalies should be evaluated more systematically during the initial diagnosis of the syndrome. In infancy, the evaluation of a child with vaginal atresia also should include the differential diagnosis of Bardet-Biedl syndrome. Vaginal atresia may either form a component of the syndrome, or girls who present with vaginal atresia in addition to other components of Bardet-Biedl syndrome might form a distinct entity.     

The preventive effect of heparin on stricture formation after caustic esophageal burns

BACKGROUND/PURPOSE: Preventing thrombus formation after caustic esophageal ingestion has been proposed to have beneficial effects. Therefore, an experimental study was carried out to investigate the effects of heparin on the esophagus after caustic burns. METHODS: Caustic esophageal burns were produced in rats by irrigation with 50% NaOH as described by Liu. Rats were divided into four groups as follows: group A, animals with esophageal burns, received placebo and underwent autopsy 48 hours after caustic injury; group B, animals with esophageal burns, received subcutaneous heparin treatment and underwent autopsy 48 hours after caustic injury; group C, animals with esophageal burns, received placebo and underwent autopsy 28 days after caustic injury; group D, animals with esophageal burns, received subcutaneous heparin treatment for 7 days and underwent autopsy 28 days after caustic injury. Histopathologic evaluation was performed in all groups, and collagen content of esophageal sections was analyzed by determination of hydroxyproline levels. RESULTS: Submucosal vascular thrombosis was encountered in all group A animals but the submucosal venules and arterioles were patent in most of group B animals. Esophageal strictures did not develop in any of group D animals, although varying degree of esophageal stenoses were encountered in all animals of group C. The circumferences of the burned segment have been narrowed to 3+/-1 mm in group C rats. There was obvious collagen deposition in submucosa, and epithelial regeneration was not complete in group C rats. Submucosa and epithelial integrity seemed normal in group D animals. Hydroxyproline contents in group D were significantly lower compared with group C (P < .05). CONCLUSIONS: Heparin has ameliorating effects on stricture formation after caustic esophageal burn. Those effects may occur through possible anticoagulant, antithrombotic, and endothelial protective effects, and modifying effects of heparin on wound healing.     

Knowledge level and attitude towards complementary and alternative treatment methods among medical students: a cross-sectional survey study in Turkey

Abstract

Objective

People often use complementary and alternative medicine (CAM) methods in Turkey, but reliability of the application of these methods is controversial. Considering the role of medical students (i.e. physician candidates) in sustainable health, their perspectives on CAM methods are important. This report explores the level of knowledge, experience, and preferences for the use of CAM methods among medical school students.     

Which is the dominant factor for perception of rheumatic pain: meteorology or psychology?

It is believed that there is an association between the weather and rheumatic symptoms. We aimed to investigate what kind of association is present and what are the factors which determine the nature of this association. Fifty-six subjects with rheumatic disease (31 RA, 15 SpA, 10 OA) who live in Antalya were followed between December 2005 and July 2006. Patients were asked to fill diaries which contain questions regarding the symptoms of their rheumatic diseases everyday. In every monthly visit, disease activity measurement, laboratory assessment and Beck depression inventory assessment were recorded. The symptomatic and psychological measurements were matched with the meteorological data of Antalya Regional Directorate of Meteorological Service of Turkish State. Correlation of symptoms with weather variables was investigated. Contributory effect of weather and of psychologic factors on symptom scores were evaluated by stepwise multiple regression analysis. Eighty-four percent of subjects belive in an association between weather and rheumatism, while 57% claimed to have ability to forecast weather. The maximum correlation coefficient between weather and arthritis symptoms was −0.451 and the maximum contribution of weather on symptoms was 17.1%. Arthritis symptoms were significantly contributed by Beck depression score. The belief about presence of weather–arthritis association was found to be stronger than its statistical power. Our results did not prove or rule out the presence of weather–rheumatism association. As long as the scientific attempts result in failure, the intuitive support in favour of the presence of weather–arthritis association will go on forever.
