Surveillance for equity in maternal care in Zimbabwe.

The great hope and promise of post-independence efforts to promote equitable health care in Zimbabwe started with three years of dramatic improvement. Commitment to correcting inequities which were as discriminatory as any country in the world produced rapid extension of health centre infrastructure and the improvement of district hospitals. The major constraint was the entrenched pattern of sophisticated, high-technology health care left by colonial administrators which continued to monopolize resources. In spite of the excellent beginning, development of services for the poor was thwarted by recession, prolonged drought and external military destabilization. The cutbacks in funding for health care have been particularly severe as a result of economic adjustment policies imposed by IMF. Political pressure moved the health system toward private entrepreneurship returning to earlier patterns of discrimination in favour of whites and urban residents. Efforts to promote high-risk monitoring have had little impact among the poor and those living in remote areas. Equity has become symbolic rather than real. The government of Zimbabwe maintains a continuing commitment to the original goals of equity through primary health care. International agencies also would like to find a way to help reallocate services. There seems to be recognition that little will be accomplished in improving health conditions unless services are provided to those in greatest need. Disparities in maternal care are especially severe and can be improved only by building infrastructure to provide antenatal and perinatal services.(ABSTRACT TRUNCATED AT 250 WORDS)

Could it be gallstones, doctor?

Gallstones may be asymptomatic, in which case they require no treatment. The author discusses symptomatic gallstones and the complications of gallstone disease. The type of presentation, appropriate investigations and treatment options are discussed.

A Model for HCO(3) Accumulation and Photosynthesis in the Cyanobacterium Synechococcus sp: Theoretical Predictions and Experimental Observations.

A simple model based on HCO(3) (-) transport has been developed to relate photosynthesis and inorganic carbon fluxes for the marine cyanobacterium, Synechococcus sp. Nägeli (strain RRIMP N1). Predicted relationships between inorganic carbon transport, CO(2) fixation, internal carbonic anhydrase activity, and leakage of CO(2) out of the cell, allow comparisons to be made with experimentally obtained data. Measurements of inorganic carbon fluxes and internal inorganic carbon pool sizes in these cells were made by monitoring time-courses of CO(2) changes (using a mass spectrometer) during light/dark transients. At just saturating CO(2) conditions, total inorganic carbon transport did not exceed net CO(2) fixation by more than 30%. This indicates CO(2) leakage similar to that estimated for C(4) plants.For this leakage rate, the model predicts the cell would need a conductance to CO(2) of around 10(-5) centimeters per second. This is similar to estimates made for the same cells using inorganic carbon pool sizes and CO(2) efflux measurements. The model predicts that carbonic anhydrase is necessary internally to allow a sufficiently fast rate of CO(2) production to prevent a large accumulation of HCO(3) (-). Intact cells show light stimulated carbonic anhydrase activity when assayed using (18)O-labeled CO(2) techniques. This is also supported by low but detectable levels of carbonic anhydrase activity in cell extracts, sufficient to meet the requirements of the model.

Knowledge and attitudes of gastroenterologists in colorectal cancer.

A group of 73 gastroenterological specialists (36 physicians, 25 surgeons, 12 trainees) completed a detailed questionnaire on their knowledge of and attitudes to colorectal cancer. A surprising unawareness of recent developments in colorectal cancer was apparent. Although responses to individual questions varied throughout the three groups, overall knowledge and attitudes on colorectal cancer were not related to age and years since graduation, and were not different in the three groups. This study suggests failure of traditional methods of continuing medical education, and has practical implications for any screening programme designed to detect early colorectal cancer.

Papillary carcinoma of the thyroid occurring as multiple vascular tumors.

A case of advanced papillary carcinoma in a 16-year-old boy is presented. While this case is typical of the indolent and locally invasive character of papillary carcinoma, it is remarkable for the extent of tumor involvement appearing as reactive lymphadenopathy. The pronounced tumor vascularity and the similarity of the needle biopsy specimen to chemodectoma both conflicted with the initial diagnostic impression. The correct diagnosis was confirmed only with definitive surgical therapy.
