Item Amoebiasis in Pondicherry (clinical, serological and immunological study).(1984-04-01) Singh, D S; Bhatia, V N; Rao, R S; Das, A K; Chandrasekar, SItem Anaerobic bacteria in acute appendicitis.(1985-12-01) Rao, R S; Babu, K R; Kakar, A; Natarajan, M KItem Bacterial adherence to cotton and silk sutures.(1992-09-01) Ananthakrishnan, N; Rao, R S; Shivam, SBACKGROUND. Silk and cotton sutures are the most commonly used materials for skin closure, the choice being largely based on tradition. We undertook this study to compare the bacterial adherence in vitro to these two materials because it is well known that the physicochemical characteristics of a suture material influence its ability to attract bacteria and consequently promote wound infection. METHODS. We determined the bacterial adherence in vitro to cotton and silk for Staphylococcus aureus and Escherichia coli, common organisms found in postoperative infection at our institute, using three inoculum strengths. The sutures were incubated with the organisms and bacterial counts per suture material calculated after 20, 60, 120 and 180 hours of incubation. The bacterial counts for the sutures were then compared at these intervals. RESULTS. The bacterial adherence for both organisms at all time intervals was significantly greater to silk than to cotton, except at 60 hours for Staphylococcus aureus. The bacterial count for each suture material appeared to be an intrinsic property of the suture and did not vary with the concentration of the bacteria in the initial inoculum. The cost of an equivalent thickness of silk is 50 times that of cotton. CONCLUSION. We suggest that cotton should be the preferred suture for skin closure because bacterial adherence to it is lower and it is much cheaper than silk.Item The biological behaviour of carcinoma of the thyroid in the elderly.(1985-03-01) Rao, R SItem Birth weight pattern in Karnataka.(1994-07-01) Prasad, K N; Rao, R S; Sujatha, AItem Blocking of oncofoetal cross-reactivity in human osteogenic sarcoma with solubilized tumour antigen.(1977-11-01) Agashe, S S; Gangal, S G; Nair, P N; Rao, R SItem Carotid body tumour-a clinicopathologic study of 10 cases.(1981-12-01) Krishnamurthy, S C; Gopinath, K S; Rao, R S; Talvalkar, G VItem Cell mediated immunity in human osteogenic sarcoma.(1975-03-01) Agashe, S S; Nair, P N; Rao, R S; Gangal, S GItem Cell mediated immunity in osteogenic sarcoma.

Their mean age was 30.3 +/- 6.4 years. Male: female ratio was 5 : 1. The heterosexual route was the major mode of transmission (96.7%). Fever was the commonest presentation (98.3%), followed by weight loss (85%) and cough (36.7%). The commonest opportunistic infection seen was tuberculosis (pulmonary, extrapulmonary - single or in combination) followed by esophageal candidiasis. Cryptococcal meningitis, intestinal crytosporidiosis, CNS toxoplasmosis, Pneumocystis pneumonia and group B Salmonella septicemia were the other infections encountered. Ten out of the 38 patients with tuberculosis were followed up on antituberculous treatment for 6 months. Seven out of 18 patients with esophageal candidiasis were treated with ketoconazole.Item Clinical staging of Hodgkin's disease.(1972-12-01) Rao, R SItem Clinical utility of serum thyroglobulin in metastatic disease.(1994-11-01) Shah, D H; Kumar, A; Vijayan, U; Dandekar, S R; Krishna, B A; Rao, R SWe examined the usefulness of serum thyroglobulin (Tg) levels in 196 patients with metastatic disease. Of these, 51 patients had a thyroidal primary (40 differentiated, 7 medullary and 4 undifferentiated), 35 patients had a nonthyroidal primary and in 110 patients the primary site was not known. Serum Tg was raised in 74.5 per cent (38 of 51) patients with carcinoma of the thyroid and in 92.5 per cent (37 of 40) patients with differentiated thyroid carcinoma (DTC). Twelve (34.3%) patients with proved nonthyroidal malignancies and 34 (30.9%) patients with unknown primary origin had elevated serum Tg levels. Of the 110 patients with unknown primary site thyroidal primary in 10 patients (all with elevated serum Tg levels) and nonthyroidal primary in 38 patients (7 had raised serum Tg levels) could be established. The sensitivity (for DTC) and the specificity (for nonthyroidal primary) of serum Tg estimation were 94.0 per cent (47 of 50) and 74.0 per cent (54 of 73) respectively and for patients with distant metastases were 100 (29 of 29) and 85.1 per cent (40 of 47) respectively. The positive and the negative predictive values of serum Tg were 71.2 (47 of 66) and 94.7 per cent (54 of 57) respectively and for patients with distant metastases were 80.6 (29 of 36) and 100 per cent (40 of 40) respectively. Our findings suggest that for patients presenting with metastases (particularly distant metastases) of an unknown primary site, serum Tg estimation is of great value to identify or rule out the involvement of the thyroid as the primary organ.Item Clinico-bacteriological study of neonatal conjunctivitis.(1990-07-01) Pandey, K K; Bhat, B V; Kanungo, R; Srinivasan, S; Rao, R SPerinatal risk factors and bacteriological profile of conjunctivitis were studied among 245 newborns delivered at JIPMER Hospital between July 1986 and June 1988. Maternal and neonatal factors like lack of antenatal care, presence of adverse intrapartum factors, operative deliveries, birth asphyxia, pre-maturity and prolonged hospital stay significantly increased the chances of developing conjunctivitis (P less than 0.001). Bacteria were recovered from 163 (66.5%) cases. Staphylococcus was the commonest pathogenic bacteria isolated, followed by Pseudomonas aeruginosa and Klebsiella pneumoniae. Neisseria gonorrhoeae was isolated in only one case. Most of the organisms showed in vitro sensitivity to chloramphenicol, gentamycin and tetracycline. All the cases responded to topical chloramphenicol except three which required systemic antibiotics. No complications were observed. The identification and appropriate management of high risk pregnancies with minimal hospital stay can reduce the incidence of neonatal conjunctivitis.Item Clubbing in a case of hypothyroidism.(2008-04-16) Mathur, S K; Sharma, B B; Choudhary, D; Rao, R S; Shibin, T S; Singh, VItem A comparative evaluation of two proteocine typing schemes.(1981-07-01) Rao, R S; Sundararaj, T; Subramanian, S; Paramasivan, C NItem Concomitant helminthiasis and recurrent upper respiratory tract infection in children of an urban community in Pondicherry.(1988-01-01) Rau, P V; Rao, R S; Sharma, S; Shah, M; Ramachandiran,; Bansal, R DItem Counter immuno electrophoresis for the early diagnosis of acute pyogenic meningitis.(1990-07-01) Dasgupta, J; Rao, R S; Kanungo, RA total of 123 cases of acute pyogenic meningitis were studied to investigate whether counter current immunoelectrophoresis (CIEP) would facilitate rapid etiological diagnosis when used with other routine methods in a clinical bacteriology laboratory. Of the 123 cases, 53 (43.08 percent) were culture positive. Streptococcus pneumoniae was the commonest etiological agent accounting for 30 (56.6 percent) of the isolates. There were four isolates of Haemophilus influenzae and one of Neisseria meningitidis. High rates of isolation were found from turbid CSF samples, those showing a high polymorphonuclear cellular reaction and from those with a high protein and a low sugar level. CIEP detected antigen in 50 percent of cases of Haemophilus influenzae and 76.7 percent of cases of Streptococcus pneumoniae.Item Counterimmunoelectrophoresis for Salmonella typhi antigen & antibody detection in typhoid.(1983-06-01) Harish, B N; Rao, R S
