OBJECTIVES The goals of this study were: (1) to obtain basic information about the effects of long-term use of mobile phones on cytological makeup of the hippocampus in rat brains (2) to evaluate the effects on antioxidant status, and (3) to evaluate the effects on cognitive behavior particularly on learning and memory. METHODS Rats (age 30 days, 120 ± 5(More)
Squamous cell carcinoma of the renal pelvis is a rare neoplasm, often unsuspected clinically due to its rarity and ambiguous clinical and radiological features, and hence patients present at advanced stages resulting in poor prognosis. We report here four cases of incidentally diagnosed primary renal squamous cell carcinoma, treated at our hospital over a(More)
BACKGROUND Malignant melanoma is the foremost cause of metastasis to the breast from extramammary solid neoplasm. However primary melanoma of the breast is a distinct rarity. Primary melanoma involves the skin and less commonly the glandular parenchyma of the breast. METHOD We herein describe a case of primary amelanotic melanoma of the breast parenchyma(More)
Craniocerebral maduromycetoma is extremely rare; only 2 cases have been reported so far. The authors report a case of maduromycetoma in a 17-year-old girl from a rural background in the state of Rajasthan, India, with involvement of the right parietal cortex, overlying bone, and subcutaneous tissue. The mass was totally excised, along with the involved dura(More)
Glioblastoma multiforme (GBM) occurs rarely in children. Relatively few studies have been performed on molecular properties of pediatric GBMs. Our objective in this study was to evaluate the genetic alterations in pediatric GBM (age < or = 18 years) with special reference to p53, p16, and p27 protein expression, alterations of the epidermal growth factor(More)
CONTEXT Muscle biopsy is at present the gold standard for the diagnosis of idiopathic inflammatory myopathies (IIMs), which include dermatomyositis, polymyositis, and inclusion body myositis. Currently, there is no definite diagnostic marker that helps in the discrimination of different subgroups of IIMs and the discrimination of IIMs from other clinical(More)
Benign central neurocytoma (CN) is a rare neuronal tumour of the central nervous system recognised since the early eighties. More than 300 articles have been published in the literature, mostly comprising of case reports and short series from individual specialties. These tumours, though normally benign, are more often likely to recur after surgery than(More)
PURPOSE Relatively few studies have been performed on molecular properties of pediatric glioblastoma multiforme (GBM). Methylation of DNA repair gene O(6)-methylguanine-DNA methyltransferase (MGMT) promoter region has been associated with favorable prognosis and prolonged survival in adult GBM patients treated with temozolomide (TMZ). We explored the(More)
BACKGROUND O6-methylguanine methyltransferase (MGMT) promoter methylation in adult glioblastomas (glioblastoma multiforme) is considered a promising molecular alteration, predictive of better response to temozolomide therapy and longer overall survival. OBJECTIVE To look at the frequency of MGMT methylation in glial tumors of all grades and types, and(More)
BACKGROUND Till date there is no published multi-institutional data regarding the epidemiological profile of pediatric brain tumors in India. AIM The present retrospective study analyses the histological spectrum of pediatric age group brain tumors in seven tertiary care hospitals in India. MATERIAL AND METHODS Data regarding frequencies of various(More)
