We describe a case of congenital intra-fourth ventricular arachnoid cyst and review the literature. A one-and-half-year-old boy had presented with delayed milestones, intermittent raised intracranial pressure and ataxia. Excision of the arachnoid cyst has cured him.
Intracranial arachnoid cysts are relatively rare; it is believed that they account for only 1% of all intracranial space-occupying lesions. When they occur in the intracranial cavity, they usually develop in relation to an arachnoid cistern as a pocket of cerebrospinal fluid within two layers of arachnoid membrane. Five cases of intradiploic arachnoid cysts… (More)
Haemangioblastomas are benign tumours of uncertain origin. They are composed of capillaries and/or cavernous spaces interspersed with interstitial cells. Malignant spread, distant metastases and subarachnoid seeding are very rare, and only two such cases have been reported in the English literature. We report a third such case in a 4-year-old girl. The… (More)
BACKGROUND Genes coding for human leukocyte antigen (HLA) class II molecules are polymorphic and have been shown to influence susceptibility to viral diseases. METHODS One hundred patients with acute chikungunya with and without viral load and 250 chikungunya negative controls from western India were studied for the distribution of HLA class II alleles by… (More)
A new xylose fermenting yeast was isolated from over-ripe banana by enrichment in xylose-containing medium. The phylogenetic analysis of ITS1-5.8S-ITS2 region sequences of ribosomal RNA of isolate BY2 revealed that it shows affiliation to genus Pichia and clades with Pichia caribbica. In batch fermentation, Pichia strain BY2 fermented xylose, producing 15 g… (More)
Clinical features and serial cerebrospinal fluid (CSF) samples of 50 patients who underwent myelography with iophendylate were studied. Forty two patients (84%) developed one or more features suggestive of meningism lasting for 2-4 days. There was significant rise in the average (mean) CSF counts from 9.81 in the premyelogram sample to 532.6 at the end of… (More)
