Central nervous system (CNS) tumors are the most frequent solid tumors in children and adolescents. The epidemiology of these tumors differs in areas of the world. However, very little data is available in the low/middle income countries (LMIC). The aim of this study is to describe the characteristics of primary childhood brain tumors treated at a leading(More)
BACKGROUND The pediatric diffuse intrinsic pontine glioma (DIPG) outcome remains dismal despite multiple therapeutic attempts. PURPOSE To compare the results of treatment of pediatric diffuse intrinsic pontine glioma (DIPG) using hypofractionated versus conventional radiotherapy. PATIENTS AND METHODS Seventy-one newly diagnosed DIPG children were(More)
Takayasu arteritis is a rare idiopathic large-vessel vasculitis that involves the aorta and its major branches. It affects young women in their child-bearing period. We present a case of a 32-year-old lady with a history of remittent fever. Magnetic resonance angiography and arch aortogram showed aortic involvement with critical stenosis of both carotid and(More)
Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone(More)
A 34-year-old Marfan patient at the seventh week of pregnancy presented with acute type A aortic dissection and severe aortic regurgitation. The aortic valve and ascending aorta were replaced successfully using circulatory arrest and deep hypothermia. At 35 weeks of gestation, the patient underwent a cesarean section and delivered a healthy baby. To our(More)
BACKGROUND Clear cell sarcoma of the kidney (CCSK) is a rare and aggressive tumor accounting for 5% of pediatric renal tumors with an incidence of 20 patients per year in the USA. It is bone metastasizing with poor prognosis. Our aim was to show characteristics of patients in relation to improved outcome in one of the developing countries. PROCEDURE We(More)
Attempts were made for using industrial and agricultural by-products and wastes as carbon and nitrogen sources in fermentation medium for alpha-amylase production by Aspergillus niger NRRL-337. The original carbon source of the basal medium was replaced by one of the following materials: rice bran, wheat bran, corn bran, corn starch, cane molasses, and(More)
INTRODUCTION Paediatric head and neck malignancy accounts for 5% of all paediatric cancers. The choice of treatment and prediction of prognosis depend on the histological type of tumour, initial staging, evaluating treatment response and detection of early recurrence. Conventional imaging modalities have many limitations. Positron emission(More)
