Primary amebic meningoencephalitis and granulomatous amebic meningoencephalitis are central nervous system infections caused by free-living amebae. We describe the neuroimaging findings in 5 such cases on CT and MR imaging. A spectrum of findings was seen in the form of multifocal parenchymal lesions, pseudotumoral lesions, meningeal exudates, hemorrhagic(More)
We tested the hypothesis that chronic treatment with sildenafil attenuates myocardial infarction (MI)-induced heart failure. Sildenafil has potent protective effects against necrosis and apoptosis following ischemia-reperfusion in the intact heart and cardiomyocytes. ICR mice underwent MI by left anterior descending coronary artery ligation and were treated(More)

Presenting features were headaches and cranial neuropathies in two patients and predominantly cerebellar dysfunction in the third. One of the patients also had(More)
BACKGROUND Solitary cysticercus granuloma (SCG) is one of the most common forms of presentation of neurocysticercosis (NCC). The diagnostic workup and management approach to this condition remain uncertain and controversial. OBJECTIVE To review evidence and develop a consensus approach to the diagnosis and treatment of SCG. METHODS A multidisciplinary(More)
OBJECTIVE The purpose of this study was to compare cerebral CT venography with MR venography and determine the reliability of CT venography in the diagnosis of cerebral sinovenous thrombosis. SUBJECTS AND METHODS Fifty patients who were clinically suspected of having cerebral sinovenous thrombosis, irrespective of age and sex, underwent cerebral CT(More)
A prospective study was conducted to look for various factors that could predict the risk of recurrence of a single unprovoked idiopathic seizure. Seventy six patients with a history of single episode of seizure ultimately completed the study and the data regarding age, sex, duration of seizure, time of occurrence of the ictus, interval between onset and(More)
Japanese encephalitis (JE) is an important arboviral infection of public health concern. There is a significant variation in mortality (10-30%) in JE viral infection. Epidemics of JE have become regular features in the northern states of India. The recent resurgence of the A226V mutation leading to a widespread Chikungunya epidemic motivated the(More)
Present study was to assess lipid peroxidation and antioxidant enzymes in the blood of the Parkinson's disease (PD) patients in the Indian population. It may be useful to develop peripheral markers, for the diagnosis and prognosis of Parkinson's disease during lifetime. Malondialdehyde content was increased in patients with PD (2 fold), with respect to the(More)
