PURPOSE To find patients at high risk of obstructive remnant leaflets after valve ablation among boys with posterior urethral valve (PUV), we evaluated any possible relationship between preoperative findings in our patients and residual obstructive leaflets after valve ablation. MATERIALS AND METHODS We retrospectively reviewed the medical records of 55 patients with PUV that was treated by t...

BACKGROUND Most empirically derived antidepressants increase monoamine levels. The nuclei of cells synthesising these monoamines are located in the brainstem, and projection tracts such as the medial forebrain bundle reach virtually all other brain areas. Two studies of unipolar depressive illness using transcranial ultrasound have reported reduced echogenicity of the brainstem midline in unipo...

The vascular network is a major target of ischemia-reperfusion, but has been poorly investigated in renal transplantation. The aim of this study was to characterize the remodeling of the renal vascular network that follows ischemia-reperfusion along with the most highly affected cortex section in a preclinical renal transplantation model. There were two experimental groups. The first was a graf...

A 17-year-old black African female from Saint Thomas and Prince with growth failure and a 5-year history of frothy urine and periorbitary oedema was referred to our department for evaluation of renal insufficiency. At admission, the patient was hypertensive and malnourished, and presented with jugular engorgement, pulmonary rales, liver enlarged to 9 cm below the right costal margin and lower l...

Introduction: Topographic anatomy of the tendons and ligaments in healthy cases provides a normal atlas to diagnose abnormalities. The aim of this study was to provide ultrasonography description of the palmar tendons and ligaments of the Anatoly donkey. Methods: The metacarpal regions of 6 healthy Anatoly donkeys were prepared for ultrasonography and divided to 6 levels (1a, 1b...

BACKGROUND AND PURPOSE Diabetes is associated with the presence of moderate to large atherosclerotic carotid plaques. Previous carotid ultrasound studies have associated plaques with low echogenicity with a higher risk of cerebrovascular events. The aim of this study was to evaluate whether patients with type 2 diabetes have different plaque echogenicity than do nondiabetic subjects. METHODS ...

BACKGROUND/AIMS Gastric schwannomas are rare benign mesenchymal tumors that are difficult to differentiate from other mesenchymal tumors with malignant potential, such as gastrointestinal stromal tumors. This study aimed to evaluate the characteristic findings of gastric schwannomas via endoscopic ultrasonography (EUS). METHODS We retrospectively reviewed the EUS findings of 27 gastric schwan...

In situ hybridization was used to quantitate the cells that produce erythropoietin (EP) in the renal cortices of mice with varying severities of acute anemia and of mice recovering from severe, acute anemia. The number of EP-producing cells in the renal cortex increased in an exponential manner as hematocrit was decreased. Individual EP-producing cells had very similar densities of silver grain...

Sir, Skin oedema is believed to have a negative effect on wound healing and to contribute to skin necrosis and the development of leg ulceration (1, 2). To understand the pathologic signi® cance of oedema, it is important to be able to determine the quantity of ̄ uid content and its localization in the skin. High-frequency ultrasonography visualizes oedema as areas of reduced echogenicity in ski...

ABSTRACT: Objective was to evaluate the accuracy of elastography in differentiation between normal and cataract lenses One hundred forty-five eyes 98 dogs were divided into groups according stage. Forty-twoeyes submitted phacoemulsification. Biometric parameters, echogenicity echotexture patterns anterior, posterior vitreous chambers, lens retina-choroid-sclera complexes evaluated by ocular ult...
