PURPOSE To evaluate the influence of the size of the light exposed pupil in one eye on the pupillary light reflex of the other eye. METHOD Using a monochromatic pupillometer, the left eye in each of 10 healthy subjects was exposed to 20 s of monochromatic light of luminance 300 cd/m(2), first red (660 nm) and in a following session, blue (470 nm) light. The consensual pupillary diameter in th...

Introduction: Ascariasis by Ascaris lumbricoides is a cosmopolitan disease. Biliary ascariasis is unusual in our country. We report a case of biliary ascariasis revealed by biliary colic. Observation: A 22-year-old woman with no particular history was received for biliary colic associated to vomiting without fever or bowel disorders. On examination, there were pain and defense at the right uppe...

A dilatation structure on a metric space, is a notion in between a group and a differential structure. The basic objects of a dilatation structure are dilatations (or contractions). The axioms of a dilatation structure set the rules of interaction between different dilatations. There are two notions of linearity associated to dilatation structures: the linearity of a function between two dilata...

balloon dilatation of stricture is one of the new treatment methods among patients with gastric outlet obstruction (goo). however, the prevalence and underlying etiologies of goo in various populations are different. the goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that would affect its success rate patients with benign etiology for g...

CASE SERIES SUMMARY This case series documents ultrasonographic and clinicopathologic features of four cats with marked segmental dilatations of the common bile duct (CBD). All cats had additional ultrasonographic changes to the hepatobiliary system, including hepatomegaly, tubular to saccular intra/extrahepatic biliary duct dilatation and biliary debris accumulation. Based on all available dat...

BACKGROUND Management of benign tracheal stenosis (BTS) varies with the type and extent of the disease and influenced by the patient's age and general health status, hence we sought to investigate the long-term outcome of patients with BTS that underwent minimally invasive bronchoscopic treatment. METHODS Patients with symptomatic BTS were treated with flexible bronchoscopy therapeutic modali...

BACKGROUND Renal transplantation (RTx) is the treatment of choice for paediatric end-stage renal disease (ESRD). A major cause of morbidity and mortality after RTx is cardiovascular disease. Independent predictors of cardiovascular events were shown to constitute an endothelial dysfunction (ED). This study aims to evaluate Visfatin serum level in comparison to brachial artery flow-mediated dila...

Long-term consequences of cardiac alteration in children with chronic renal failure and after renal transplantation are largely unknown. In chronic uremia, cardiomyopathy manifests itself as systolic dysfunction, concentric left ventricular hypertrophy (LVH) or left ventricular dilatation. The correction of uremic state by renal transplantation leads to normalization of left ventricular contrac...

AIMS Calcific coronary lesions impose a rigid obstacle to optimal balloon and stent expansion and the 20 to 30 atm limit that non-compliant (NC) balloons reach can be insufficient. The aim of our study was to evaluate the safety and efficacy of a new dedicated super high-pressure NC balloon (OPN NC®; SIS Medical AG, Winterthur, Switzerland). METHODS AND RESULTS We retrospectively evaluated a ...

The aim of this study was to explore the clinical effect of endoscopic minimal invasive surgery on posterior urethral stricture with false passage. Twenty-one patients suffering from posterior urethral stricture with false passage were involved in the study. All the patients received pre-operative urethrography and flexible cystoscopy to make sure that the distance between the blind end of the ...
