Fungal rhinosinusitis: A prospective study in a University hospital of Uttar Pradesh.

Background: To assess the purpose of fungal rhinosinusitis in a University hospital and to correlate histopathological findings with culture results for accurate clinical classification of the disease. Materials and Methods: One-hundred suspected patients were included in the study. Data was collected in a brief predetermined format. Samples like nasal lavages, sinus secretions, and tissue specimens were processed and examined by microbiology culture using recommended techniques. Slide culture was done to observe the microscopic morphology. Histopathological examination was done by H and E stain and PAS stain for classification. Results: Out of 100 cases of rhinosinusitis, 21 cases were culture-positive for fungal rhinosinusitis. On the basis of histopathological findings, 14 cases (66.67%) were found to be of non-invasive fungal rhinosinusitis. Aspergillus flavus was the most common fungal isolate. Conclusion: Mycological profile of rhinosinusitis in Lucknow was thus evaluated. Histopathological and microbiological findings reported 21 cases of fungal rhinosinusitis among 100 suspected cases of rhinosinusitis.

In vitro regeneration of roots of Phyla nodiflora and Leptadenia reticulata, and comparison of roots from cultured and natural plants for secondary metabolites.

Adventitious roots, generated using leaf explants of P. nodiflora, and meristem explants of L. reticulata, were cultured on Murashige and Skoog (MS) medium supplemented with napthylacetic acid (2 microM) and indole butyric acid (3 microM) respectively. After 30 days, subculturing of roots in liquid MS medium with napthylacetic acid (1.5 microM) for P. nodiflora and indole butyric acid (3 microM) for L. reticulata afforded considerable increase in root mass. HPTLC profiles and microscopic examination of transverse sections of in vitro and naturally grown roots provided information on secondary metabolite accumulation vis-à-vis developmental stages of the root.

Alopecia universalis in a case of systemic lupus erythematosus.

We report a case of systemic lupus erythematosus (SLE) who presented with alopecia universalis. MR, a 23 years female patient was admitted with alopecia universalis and other features of SLE like peripheral arthritis, fever, nephritis, butterfly rash over the malar regions, positive ANA and anti-ds DNA antibodies. There was a gap of four years between the onset of alopecia universalis and other clinical features of SLE. The alopecia was of non-scarry variety and responded to systemic and topical steroids.

Surgical filariasis: immunoscreening for filarial IgG antibodies using Wuchereria bancrofti microfilarial excretory-secretory antigen.

A clinical study and immunoscreening was conducted on 363 suspected filarial patients attending the surgery out patient division of the MGIMS, Sevegram. The disease was significantly higher in males (86%) than in females (14%). Majority (52.9%) of the cases were in the age group of 11-30 years. The distribution of cases into three different grades of infection showed, 52.6%, 33.3% and 14.1% of the cases having acute (grade I), sub-acute (grade II) and chronic (grade III) stages of infection respectively. While 73% of the cases had genital manifestations, 23% were with lymphatic obstruction in limbs and the rest of the 4% suffered from manifestations like cellulitis, abscesses, haematuria and chyluria. Filarial IgG antibodies against microfilarial excretory-secretory (mf ES) antigen were detected in 89% of cases with genital manifestations, 87% of lymphoedema cases, 67% of lymphadenitis cases and 60% of cases with other clinical manifestations and 3% of endemic normals.

A study on transferable R-plasmids among Shigella species at Lucknow.

A total of 500 Shigella strains were included in the present study out of which 233 were isolated at National Shigella Centre of Postgraduate Department of Microbiology, K.G. Medical College, Lucknow during last 5 years and 267 strains were received from different parts of the country. Predominent serotypes were Sheigella flexneri 292 (48.4%) followed by Shigella dysenteriae 153 (30.6%), Shigella boydii 32 (6.4%) and Shigella sonnei 23 (4.6%). All the strains were sensitive to Nalidix acid, Gentamycin, Kanamycin, Neomycin and Furazolidine. Varying degree of resistance was shown to Streptomycin, Chloramphenicol, Tetracycline and Ampicillin. R. plasmid extraction was done and transfer was studied on E. Coli K-12.

Nosocomial infection due to enterobacter cloacae in a tertiary care hospital in northern India.

A total of 151 Enterobacter cloacae strains isolated from clinical samples (n = 139) and the hospital environment (n = 12) at a tertiary care hospital in northern India during January to October 1993, were analysed. The maximum isolations were during May (n = 24), June (n = 23) and July (n = 22). Urinary tract infection (n = 56) was the most common complication of E. cloacea infection followed by wound infection (42), respiratory tract infection (23) and bacteraemia/septicaemia (18). The frequency of resistance to different drugs was ampicillin 77.4 per cent, cotrimoxazole 79.5 per cent, gentamicin 57.5 per cent, cefotaxime 47 per cent and ofloxacin 36 per cent. Sixty three (41.7%) strains exhibited resistance to multiple drugs. Environmental isolates from bed, hospital diet, hand swab and water from a leaking drain pipe in a ward showed the same resistance pattern. A single index strain could not be identified using phage and biotyping, indicating that a variety of strains were responsible for the nosocomial infection. Adoption of strict aseptic measures and repair of the pipe brought down the infection rate.
