INTRODUCTION Ulcerative colitis occurs worldwide. It is considered common in most of Europe and North America and uncommon in most of the developing Asian countries. The incidence/prevalence of ulcerative colitis varies not only according to geographical region but also with race and ethnicity. There are no reported data from India on the incidence of the(More)
BACKGROUND Celiac disease, as of today, is said to exist in almost all parts of the world, although it is rare among people of purely African-Caribbean, Japanese and Chinese background. The disease has also been considered uncommon in India until recently. Hospital records have revealed an increasing trend of the disease in predominantly wheat-eating areas(More)
OBJECTIVES AND METHODS A prospective evaluation of the correlation between the serial clinical findings, serum cholinesterase levels, electrodiagnostic abnormalities and the daily atropine requirement was undertaken in 29 patients with confirmed acute organophosphate poisoning (OPP). RESULTS Clinical weakness conforming to the pattern found in(More)
BACKGROUND Azathioprine is useful as a steroid-sparing drug in patients with ulcerative colitis. Its role as monotherapy in the maintenance of disease remission has not been evaluated. METHODS In this prospective, randomized, open-label study, 25 patients with severe ulcerative colitis received either azathioprine (2.5 mg/Kg/day; Group A, n = 12) or(More)
The spectrum of acute renal failure is different in intensive care unit (ICU) vs. non-ICU population. This one year prospective study carried out in medical and surgical intensive care units showed an incidence of 8.6% of acute renal failure. The incidence of acute renal failure was highest in medical ICU (17.2%) followed by burns ICU (5.3%), pulmonary ICU(More)
PURPOSE A focal cortical-subcortical calcification (FCSC) is a common finding on computed tomography (CT) in individuals with focal or generalized seizures in the Indian subcontinent. We sought to determine the relation of FCSCs to epilepsy by comparing the lobe of seizure origin by electroclinical and CT evaluations and to study the nature and severity of(More)
AIMS To determine the etiologic role of neurocysticercosis (NC) in a hospital-based sample of epilepsies divided according to International League Against Epilepsy (ILAE) epidemiological criteria and number of seizures prior to presentation. METHODS A sample comprising 1026 consecutive patients with either definite seizures or epilepsy attending a(More)
Phrenic nerve conduction studies were performed within 48 h of admission and subsequently in 29 patients (14 of whom required mechanical ventilation) with acute organophosphate (OP) poisoning. The mean (+/-SD) amplitude of the diaphragmatic compound muscle action potential (CMAP) in patients requiring mechanical ventilation (119.09 +/- 173.85 microV) was(More)
