A novel hybrid tobacco product that delivers a tobacco flavour note with vapour aerosol (Part 2): In vitro biological assessment and comparison with different tobacco-heating products.

This study assessed the toxicological and biological responses of aerosols from a novel hybrid tobacco product. Toxicological responses from the hybrid tobacco product were compared to those from a commercially available Tobacco Heating Product (c-THP), a prototype THP (p-THP) and a 3R4F reference cigarette, using in vitro test methods which were outlined as part of a framework to substantiate the risk reduction potential of novel tobacco and nicotine products. Exposure matrices used included total particulate matter (TPM), whole aerosol (WA), and aqueous aerosol extracts (AqE) obtained after machine-puffing the test products under the Health Canada Intense smoking regime.

Hookworm infection and reinfection following treatment among Orang Asli children.

In hookworm endemic areas where sanitation is often wanting, reinfection of treated children is a problem. This study was conducted to enumerate the prevalence and the reinfection rate of hookworm in 193 Orang Asli children following treatment with stat dose of 400mg of albendazole at 2 and 4 months post-treatment. All samples were examined using the Kato-Katz and Harada Mori techniques.

Hypercalcemia in a patient with tuberculous mediastinal lymphadenopathy.

We describe the case of a 48 year old Indian female with hypercalcemia due to tuberculosis. She presented with symptoms of hypercalcemia and chest radiographs showed bilateral hilar lymphadenopathy with normal lung fields. The diagnosis of tuberculosis was made histologically from biopsy of the enlarged hilar nodes.
