Isolation of intestinal spirochaetes from homosexuals

Spirochaetes were isolated from rectal swabs of two homosexuals and the faeces of a third, using simple isolation techniques not previously applied to specimens of this type. The ease of culture of these organisms will enable their distribution and pathogenicity to be studied, particularly in relation to their significance in homosexuals.     

Evaluation of Race by Cranial Index of Adult Human Skull in Maharastra Population

Biologists and physical anthropologists attempted to classify human being into races according to phenotypic variations. The latter are based either on one or two phenotypic characters therefore the outcome is unable to givq clear distinction among different races. Cranial index seems to be an important,tool, which may be used to identify the races in different geographical regions. 75 dried skulls collected from different part of Maharashtra were measured to determine the cranial index. Skulls were classified by the method of Montagu (1960)2 Average maximum cranial length and breadth were found to be 17.11 cm and 12.98 cm respectively and maximum & minimum cranial lengths were observed to be 18.50 and 16.60 cm and cranial breadths were noted to be 14.50 and 12.10 cm respectively. Average cranial index (mean ± SD) was 75.49 ± 3.95. In our study most of the skulls were grouped under the Mesocranial (46.66%) and Dolichocranial (42.66%) categorises when based on Montagu and Dolichocranial categorises when 56% based Comas'. As per the conclusion Maharashtrian population belongs to Indo-Dravidian race.     

Substance abuse treatment duration for Medicaid versus commercial clients in a health maintenance organization

BACKGROUND: As Medicaid clients have come to be enrolled in managed care, concerns have arisen about the ability of private sector systems to meet the needs of enrollees with substance abuse problems. OBJECTIVES: This project describes treatment initiation and duration for Medicaid and commercial substance abuse treatment clients in a large health maintenance organization (HMO). RESEARCH DESIGN: This study was a prospective secondary analysis of information from HMO databases. Subjects were 641 adult Medicaid clients who contacted the HMO's addiction medicine department in 1996 or 1997 and commercial HMO addiction medicine patients (n=447). First contact with addiction medicine during the study period was the index event. MEASURES: Chief dependent variables were initiation and duration of substance abuse treatment after the index event. RESULTS: Logistic regression showed that longer HMO enrollment predicted treatment initiation after substance abuse assessment, but Medicaid status was not a significant predictor. A competing risks analysis using Cox proportional hazards models indicated that once subjects had initiated, Medicaid was not significantly related to exit from substance abuse treatment. Analysis of health plan disenrollment by Medicaid clients indicated that the most common reason was loss of Medicaid eligibility. CONCLUSIONS: These results raise the possibility that state Medicaid policies may make it difficult for clients to obtain suitable chemical dependency treatment services.     

The long-term effectiveness of generic adult fixed-dose combination antiretroviral therapy for HIV-infected Ugandan children

Background

Access to pediatric antiretroviral formulations is increasing in resource-limited countries, however adult FDCs are still commonly used by antiretroviral therapy (ART) programs.

Objective

To describe long-term effectiveness of using adult FDC of d4T+3TC+NVP (Triomune) in children for HIV treatment.

Methods

Clinical, immunologic, and virologic outcomes of HIV-infected ART-naïve children aged six months to 12 years, were evaluated up to 96 weeks post-ART initiation.

Results

From March 2004 to June 2006, 104 children were followed with a median age of 5.4 years, median CD4 cell percent and HIV-1 RNA were 11.0% (IQR 6.7–13.9) and 348,846copies/mL (IQR 160,941–681,313) respectively at baseline. Using Kaplan-Meir estimates, 75% of children had undetectable viral loads (<400copies/mL) at 96weeks of ART. Children with a baseline CD4 cell percent >15% were 3 times more likely to achieve viral load <400copies/mL than those with baseline CD4 cell percent <5% after adjusting for baseline age {aHR = 3.03 (1.10–8.32), p=0.03}; no difference was found among those with CD4 cell percent >5–14.9% and <5%.

Conclusion

Treatment with generic adult FDC for HIV-infected Ugandan children led to sustained clinical, immunologic and virologic response during 96 weeks of ART. Early initiation of ART is key to achieving virological success.
