Efficacy of diethylcarbamazine medicated salt in interrupting Brugia malayi transmission in hill tribe settlements in Kerala State.
A filariasis survey carried out about eight years after achieving zero microfilaria (mf) rates following administration of diethylcarbamazine (DEC) medicated salt in the Kani hill tribe settlements in Quilon and Thiruvananthapuram districts of Kerala State revealed that there was no reappearance of Brugia malayi infection in the experimental areas. Mf rates were maintained at zero level in the experimental villages, while in the control villages, 2.9 per cent mf positives were observed. Mansonia (Mansonioides) uniformis dissected did not reveal filarial infection. It is concluded that DEC medicated salt regime in the experimental areas of Kani hill tribe settlements has been successful in effectively interrupting B. malayi transmission. Pilot studies in other B. malayi endemic areas of India using DEC medicated salt regime with the objective of eliminating B. malayi transmission are advocated, since the parasite has a restricted distribution in India and is already showing a declining trend.

Methotrexate: clinical and immunological effects in refractory rheumatoid arthritis.
Thirty five patients with refractory rheumatoid arthritis were given 7.5 mg of methotrexate (Mtx) every week. Eleven patients had to discontinue treatment either because of adverse effects or unresponsiveness. Twenty four patients showed clinical response and significant improvement in ESR and they continued Mtx for a mean of 25.24 months. Seven patients achieved clinical remission as defined by ARA criteria. Immunological parameeters including IgG, IgM, IgA, lymphocyte subsets (CD3+, CD4+, CD8+ and B), C3 and C4 however, did not show any change during this treatment in any of the groups upto 6 months. There was a significant fall in the erythrocyte sedimentation rate (ESR), c-reactive protein (CRP) and rheumatoid factor (RF) levels in responders only.

Primary structures of alcohol and aldehyde dehydrogenase genes of Entamoeba histolytica.
Ethanol is the major metabolic product of glucose fermentation by the protozoan parasite E. histolytica under the anaerobic conditions found in the lumen of the colon. With the goal of finding new targets for anti-amebic drugs, the E. histolytica NADP(+)-dependent alcohol dehydrogenase gene (EhADH1; EC 1.1.1.2) and an aldehyde dehydrogenase gene (EhALDH1; EC 1.3.2) were cloned. The EhADH1 alcohol dehydrogenase gene encoded -39 kDa protein with 62 and 60% amino acid identities, respectively, with NADP(+)-dependent alcohol dehydrogenases of anaerobic bacteria Thermoanaerobium brockii and Clostridia beijerinckii. In contrast, EhADH1 showed a 15% amino acid identity with the closest human alcohol dehydrogenase. An EhADH1-glutathione-S-transferase fusion protein showed the expected NADP(+)-dependent alcohol dehydrogenase and NADPH-dependent acetaldehyde reductase activities. The enzymatic activities of the EhADH1 fusion protein were inhibited by pyrazole and 4-methyl pyrazole. The E. histolytica aldehyde dehydrogenase EhALDH1 gene encoded a 60 kDa protein, which showed a 36% amino acid identity over a 451 amino acid overlap with the human stomach aldehyde dehydrogenase (ALDH3).

Status of lymphatic filariasis in some select slum clusters of Delhi.
Filaria surveys conducted in some select slum clusters namely Hari Nagar, Yamuna pusht near Vijaya Ghat along the Ring Road and Timarpur in Delhi during 1989, 1991 and 1992 respectively, covering a population of approximately 5000 slum dwellers revealed the presence of bancroftian microfilaria (mf) carriers and disease cases. The mf and disease rates (per cent) in these three slum areas were in the order of 6.3, 2.2, 3.7 and 1.4, 0.5 and 0.1 respectively. The mf density varied from 3.1 to 12.3 per 20 cumm. blood. High ten man hour densities of Culex quinquefasciatus (581) in Yamuna pusht followed by (355) in Timarpur were recorded during entomological investigations. Hari Nagar accounted for least ten man hour density of Cx. quinquefasciatus (160), because collection was made during winter months (November-December). The dissection of Cx. quinquefasciatus did not reveal any human filarial infection except in Yamuna pusht where out of 139 only one Cx. quinquefasciatus was found infective.

Hepatitis C virus infection in chronic liver disease in Bombay.
To find out the prevalence of antibody of hepatitis C virus (anti-HCV) in patients with chronic liver disease in Bombay, sera from 126 patients (93 men, 33 women; aged 9-70 years, mean 39.7) with chronic liver disease (cirrhosis 103, cirrhosis with hepatocellular carcinoma 3, chronic active hepatitis 20) were tested for HBsAg and anti-HCV antibody. HBsAg positive sera were tested for anti-delta antibody and IgM anti-HBc. All the tests were carried out by ELISA. Of 126 patients, 51 (40.5%) were HBsAg positive, 49 (38.8%) alcoholic and 21 (16.6%) anti-HCV positive. The prevalence of anti-HCV in HBsAg positive, alcoholic and cryptogenic (HBV negative and no alcohol) liver disease patients was 13.7%, 14.7% and 20.5% respectively. Of 21 anti-HCV antibody positive patients, 8 (38%) had received blood transfusions previously. HCV is present in 15-20% of patients with chronic liver disease in Bombay.

Ultrasonography-directed native renal biopsy: comparison of an automated biopsy device with a needle system.
The authors compared the performance of an automated biopsy device with a large-bore cutting needle system in ultrasonography-guided native renal biopsy. They retrospectively analysed 52 biopsy specimens from 50 adults with diffuse renal parenchymal disease. Twenty-six consecutive biopsy samples had been obtained manually with a 14-gauge needle (Tru-Cut, Travenol Laboratories, Deerfield, Ill.); a second set of 26 samples had been obtained with a biopsy gun (Bard Biopty, Radiplast, Uppsala, Sweden) fitted with a 14-gauge needle of similar design. The systems were compared in terms of the specimens obtained (the adequacy and the quality of tissue, the number of intact glomeruli and the presence of artifacts) and the incidence of biopsy-related complications. Biopsy specimens obtained with the biopsy gun were judged qualitatively as well as quantitatively superior; they contained an average of 17.6 intact glomeruli, whereas only 11.5 intact glomeruli were retrieved with the needle system. Although the incidence of minor complications was lower after biopsy with the automated gun than after use of the needle system (8% and 15% respectively), two major complications were observed after gun biopsy and none after needle biopsy. The results reported here indicate that for native renal biopsy the Biopty gun delivers a higher-quality tissue core with a lower frequency of minor complications, but not of major complications, than the Tru-Cut needle system.

HIV infection in patients of liver cirrhosis.
A total of 130 patients of liver cirrhosis (97 males, 33 females; aged 9-70 yr) of various etiologies were subjected to anti HIV antibodies testing by ELISA and supplementary Western Blot (WB) tests. Eleven patients were positive by ELISA. Of these 11 patients, 5 were WB positive, 4 were WB negative and 2 were indeterminate. Of the 5 WB positive patients none had received blood transfusions and one was a homosexual. These results indicate that HIV infection was present in 3.8 per cent patients of liver cirrhosis. Further studies are required on a large number of patients to recommend HIV testing routinely in cirrhotic patients.

Peribulbar anesthesia in retinal reattachment surgery.
We prospectively evaluated the effectiveness of peribulbar anesthesia in retinal reattachment surgery. Of the 24 patients studied, 2 required retrobulbar supplementation during the latter part of the surgery. Our results show that peribulbar anesthesia can be effectively used for retinal reattachment surgery and probably should be the preferred form of local anesthesia for this surgery, since the eyes involved have a relatively high incidence of axial myopia and posterior staphyloma.

Frequency of hepatitis B, C and D and human immunodeficiency virus infections in multi-transfused thalassemics.
Of forty multi-transfused thalassemia patients (26 males, 14 females; mean age 8.1 +/- 5.3 years, range 1-35) with no clinical or biochemical evidence of liver disease, HBsAg, anti-hepatitis C virus and anti-human immunodeficiency virus antibodies were present in 18 (45%), 7 (17.5%) and 1 (2.5%) cases respectively. Three of the 18 (16.7%) HBsAg positive patients were anti-delta antibody positive. Our results indicate that more than 50% of multi-transfused thalassemia patients show serological evidence of one or more of hepatitis B, C and D and human immunodeficiency virus infection.

Intermittent intravenous pulse cyclophosphamide treatment in systemic lupus erythematosus.
To determine the efficacy and safety of intermittent intravenous pulse cyclophosphamide in patients of severe systemic lupus erythematosus (SLE), 50 patients having severe/refractory lupus nephritis, vasculitis or neuropsychiatric manifestations were treated with 3 weekly pulses of cyclophosphamide for 6 such pulses. This treatment was found to be associated with significant and sustained improvement during a 2 yr follow up with respect to the mean renal activity score, individual renal parameters (proteinuria, erythrocyturia, and serum creatinine levels), focal neurological manifestations, vasculitic lesions, antinuclear antibody titers, complement component C3, anti-dsDNA antibodies levels and ESR. There was a sustained decrease in the overall mean disease activity score, and the mean daily dose of prednisolone (pretreatment 32.62 mg daily to 3.75 mg daily after 24 months). There was a significant decline in the percentage and absolute B cell count after 7, 14 and 21 days of this treatment. Effect on other lymphocyte subsets (CD3+, CD4+ and CD8+) was not marked. Pulse cyclophosphamide could therefore be an effective and less toxic form of treatment in patients with SLE having severe lupus nephritis, focal neurological lesions or vasculitis.
