Pulmonary arteriovenous malformations (PAVM) are abnormal communications between pulmonary arteries and pulmonary veins, and most commonly congenital in nature. Although rare, it is an important consideration in cyanotic patients of unknown cause. We report 3 cases with diffuse PAVM in children with different clinical manifestations and initial diagnosis was made by transthoracic contrast echoc...

A more detailed analysis is made of the energy spectrum of the diffuse component of extragalactic gamma rays over the range of 0.3- 10 GeV, obtained fromthe EGRET instrument at the Compton Gamma Ray Observatory. The derived excess energy spectrum of high galactic latitude, b > 60°, using intercept method shows that it is correlated with Virgo cluster (over lsr) and average Virgo intensity i...

SUMMARY In order to evaluate the long-ter m effects of antithyroids and ahlative therapy on patients with toxic diffuse goiter (TDG) in an iodine deficient region, 206 patients were studied in Tehran. Hyperthyroidism recurred in 50%, of 80 patients treated with Methimazole (MMI), from one week to 48 months after cessation of therapy. Another 40 patients remained in remission. Of 102 patients t...

BACKGROUNDS: Seminoma is frequently observed in human and canine testes especially in cryptorchids. Canine and human seminomas are typically associated with leukocytic infiltration. OBJECTIVES: We aimed to identify the type of lymphocytes that infiltrate to seminomas. METHODS: Tumor infiltrating lymphocytes were evaluated by immunohistological techniques in 5 dogs with diffuse seminoma. Routine...

a 22 year old male referred with palpitation. general appearance and physical exam impressed us in that the patient has marfan syndrome. cardiac catheterization showed diffuse arterial ectasia. we found no previous report of this generalized diffuse ectasia.

The purpose of this study was to describe the pattern of diffuse enhancement seen on contrast-enhanced MR images in patients with subacute infarction. A retrospective study of 104 patients with the diagnosis of stroke who had undergone contrast-enhanced MR scanning within2 weeks of the inciting neurological event revealed 66 patients who demonstrated different patterns of contrast-enhanceme...

primary hepatic lymphoma is a rare malignancy usually presenting with symptoms of fever, hepatomegaly, jaundice and weight loss. this picture mimics infectious and inflammatory disorders and thus delays the diagnosis. here, we present a 47-year old man with prolonged fever who underwent several investigations and, in the meantime, developed fulminant hepatic failure before the diagnosis could b...
