Lathyrism, a form of motoneuron disease induced by excessive consumption of th legume Lathyrus sativus (chickling pea), presents as signs of pyramidal tract involvement. Primate feeding studies show that beta-N-oxalylamino-L-alanine (BOAA), a potent neuroexcitatory aminoacid in the chickling pea, induces corticospinal dysfunction similar to that seen in(More)
Proanthocyanidin is commonly used for inhibiting urinary tract infection (UTI) of sensitive strains of Escherichia coli. The aim of this study was to investigate the effect of proanthocyanidin on adherence of uropathogenic multi-drug resistant E. coli to uroepithelial cells, which has not yet been investigated so far. Extracts of the purified(More)
Fulminant hepatic failure (FHF) associated with parvovirus B19 (B19) infection has a favorable prognosis in children. However, there is no data available to predict outcome in cases of FHF associated with hepatotropic virus coinfection. Clinical characteristics of 3 pediatric groups with FHF were compared and it was observed that B19 coinfection with other(More)
An important risk factor for nosocomial infection in an intensive care unit (ICU) is prior colonization. This study was undertaken to determine the spectrum of bacterial colonization and predisposing risk factors in patients being admitted to an ICU in India, with special emphasis on extended-spectrum beta-lactamase (ESBL)- and metallo-beta-lactamase(More)
CONTEXT Ventilator-associated pneumonia (VAP) is a leading nosocomial infection in the intensive care unit (ICU). Members of Enterobacteriaceae are the most common causative agents and carbapenems are the most commonly used antibiotics. Metallo-beta-lactamase (MBL) production leading to treatment failure may go unnoticed by routine disc diffusion(More)
Lathyrism is a toxic disease of the motor system constantly associated with primary consumption of the seed of Lathyrus sativus (chickling or grass pea). Neurological examination was performed on 38 affected subjects drawn from four regions of the Indian subcontinent endemic for lathyrism. All showed a consistent and largely symmetric pattern of(More)
In this study early lepromin reaction has been used to detect delayed hypersensitivity reaction to a prior infection with M. leprae, recent studies indicate that a certain number of contacts who develop sub-clinical infection remain anergic to the lepromin test. This is indicated by the Fluorescent leprosy antibody absorption (FLA-ABS) test of Abe (1979)(More)
The (1)H NMR spectroscopic method is suggested and its utility is demonstrated for the diagnosis of Klebsiella pneumoniae (K. pneumoniae) in urinary tract infection (UTI). K. pneumoniae have the specific property of metabolizing glycerol to 1,3-propanediol (1,3-PD), acetate, ethanol and succinate. The quantity of 1,3-PD produced correlates well with the(More)
OBJECTIVE To address the shortcomings of urine culture for the diagnosis of urinary tract infection (UTI), we used 1H-nuclear magnetic resonance (NMR) spectroscopy for identifying and quantifying Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumonia and Proteus mirabilis. PATIENTS, SUBJECTS AND METHODS Urine samples from patients with suspected(More)
