The Pneumonia Etiology Research for Child Health (PERCH) project is the largest multicountry etiology study of childhood pneumonia since the Board on Science and Technology in International Development studies of the 1980s. However, it is not the only recent or ongoing pneumonia etiology study, and even with seven sites, it cannot capture all epidemiologic settings in the developing world. Fund...

Twenty-eight active international athletes agreed to be available for random spot urine collections at their homes, places of work and training. Suitable briefed collectors were arranged to conduct the spot collections and forward the specimens for analysis. An average number of 3.4 collections per athlete was made in the 9 month period of the trial. Overall there was a "failure to collect" per...

Method: 36 male 9-10 years children were invited to participate in this study, and 30 completed a 24 h urine collection. The Free Water Reserve (FWR) was used to assess the hydration status; additionally, a food record corresponding to the day of urine collection and a lifestyle, and socio-demographic questionnaire was filled with parents help. Anthropometric data were obtained. Food and bevera...

Non-traditional settings offer an opportunity to increase access to sexually transmissible infection testing for at-risk populations, but they have not yet proven to be an efficient option and current models are unlikely to be effective if scaled up.

A capillary tube holder, devised to minimize shadow effects during microscopic examination of haematocrit capillary tubes for trypanosomes, is described. A blood dispenser, designed to remove trypanosomes from centrifuged tubes, resulted in thinner smears of trypanosomes covering a smaller area. The anterior end of centrifuged trypanosomes was abnormally thickened and the kinetoplast displaced ...

Aims: To report the histopathology of two specimens of polypoidal choroidal vasculopathy (PCV) obtained from two eyes of Japanese patients. Methods: Specimens were obtained under direct visualisation during macular translocation surgery with 360 degree retinotomy. The clinical findings were correlated with the light microscopic findings of the two specimens. Results: One specimen from a 77 year...

A novel capillary tube has been tested and evaluated experimentally in the refrigeration cycle of window type air conditioner. Three twisted capillary tubes have been demonstrated and evaluated to show the performance of these tubes and its ability in the depressurization process seeking for short capillary tube. The effect of twist angle and the number of twisted points on the refrigeration cy...

Procedures have been designed to test specimen containers for leakage, using blood and aqueous fluorescein solution as indicators. They have been used in a trial evaluation of a number of commercially available containers intended for medical specimens. Glass bijou bottles, evacuated container systems, and several types of plastic container showed no significant leakage rate with either blood o...
