Outbreak of Salmonella worthington meningitis & septicaemia in a hospital at Chandigarh (north India).

During August 1988 an outbreak of hospital acquired infection due to S. worthington has been reported at the Nehru Hospital, Postgraduate Institute of Medical Education and Research, Chandigarh. A total of seven neonates presented with the clinical features of meningitis and septicaemia during this outbreak and six babies died. S. worthington was isolated from blood and cerebrospinal fluid respectively. The same strains were isolated from the baby warmer mattress, baby cot, suction machine bottle and wall of the fridge. Samples from doctors, nurses and apparently healthy babies born during this period did not grow the above organism. This appears to be the first report on S. worthington in human beings from India. The outbreak was controlled by thorough cleaning and fumigation. The organisms were also mostly sensitive to antibiotics used, in contrast to the multiple drug resistant pattern reported from elsewhere.

The value of fine-needle aspiration biopsy in the cytodiagnosis of salivary gland lesions.

Fine-needle aspiration cytology (FNAC) was performed on 195 cases of salivary gland lesions. The smears were technically adequate in 178 cases. Tissue examination was available for subsequent histocytologic correlation in 57 cases. The cytodiagnosis included inflammatory lesions (59) and benign (68) and malignant (51) tumors (total, 119). The accuracy of cytodiagnosis was 87.7% with a sensitivity of 80.9% and a specificity of 94.3%. Exact histologic typing was possible in 61.9% of the malignant tumors. Mucoepidermoid tumors and cellular-atypical pleomorphic adenoma posed difficulties in cytodiagnosis.

Nuclear morphometric analysis of non-Hodgkin's lymphoma.

Nuclear morphometric data on resin-embedded sections have been utilized to classify 50 cases of non Hodgkin's lymphoma (NHL) and to compare with morphological classification. Nuclear morphometric parameters studied were maximum diameter (Dmax), area, perimeter, form factor (FF) and nuclear contour index (NCI). The first three are determinants of the size, and the latter two indicate the shape of nuclei. Based on Dmax, small (4.5-5.5 microns), intermediate (5.5-7.0 microns) and large (7.0-12.0 microns) cell lymphomas were identified, which correlate with the low, intermediate and high grade lymphomas respectively of the Working Formulation. Determination of form factor further helped to subclassify these cases into lymphomas of B cell other than of follicular centre cell origin (FF = 0.7-1.0), follicular centre cell lymphomas (FF = 0.55-0.75) and T-cell lymphomas (FF less than 0.55). Pleomorphism factor is an objective assessment of the degree of morphological pleomorphism and is generally proportional to the grade of malignancy.

Intrabronchial schwannoma. A case report.

A 17-year-old male presented with clinical features of left lung collapse. The diagnosis of isolated intrabronchial schwannoma was obtained by endoscopic biopsy and confirmed after pneumonectomy.

Experimental haematogenous pyelonephritis in mice with uropathogenic, enteropathogenic and enterotoxigenic Escherichia coli.

Acute haematogenous pyelonephritis was produced with known uropathogenic (075), enteropathogenic (0111) and enterotoxigenic (H10407) Escherichia coli in mice. The enterotoxigenic E. coli showed the highest bacterial counts in kidney and urine and was found to have the same potential for causing pyelonephritis as a known pyelonephritogenic strain both in untreated and corticosteroid treated mice. Enteropathogenic E. coli was found to be less pyelonephritogenic in untreated mice, but under the effect of corticosteroids it showed similar pyelonephritogenic potential.
