Failure of national guidelines to diagnose uncomplicated malaria in Bangladesh.

During the mid 1990s, national guidelines were established in accordance with World Health Organization recommendations for the diagnosis of uncomplicated malaria in Bangladesh. Based on simple clinical and epidemiologic criteria these guidelines were designed to be applied outside of tertiary care centers where microscopy was not feasible. We evaluated the positive predictive value (PPV) of these criteria using microscopic slide examinations as the gold standard in 684 subjects diagnosed and treated for malaria, sampling from eight subdistrict centers. The PPV for malaria was 32% with 19% for falciparum and 14% for Plasmodium vivax. Medical officers assigned to the study also gave their own clinical impression of whether cases could have been malaria. With the additional criteria of a medical officers' diagnosis, the PPV increased negligibly to 37% with 23% and 14% for falciparum and vivax, respectively. Since the PPV of diagnosis is low and cannot be improved on clinical grounds alone, we recommend the incorporation of laboratory diagnosis. This is especially important as we detect resistance to the first-line therapy chloroquine and require more expensive, potentially more toxic, regimens.

Quinacrine non-surgical female sterilization in Bangladesh.

This study was undertaken to evaluate the efficacy, safety, and acceptability of transcervical applications of quinacrine along with other adjuvants, such as ampicillin and ibuprofen, for sterilization. The cohort consisted of 750 normal women who requested sterilization and volunteered for this method at the family planning clinic of a tertiary hospital and community clinics in Chittagong, Bangladesh. Several different protocols were followed from October 1989 to April 1999. Each woman received one or two insertions of 180 mg or 252 mg quinacrine with or without adjuvants including 55.5 mg ibuprofen or 125 mg ampicillin. Supplementary contraception was given in the form of combined oral contraceptive pills, barrier methods, or injection of depot medroxyprogesterone acetate for 3 months. Details of each protocol are described in the text. The gross pregnancy failure rate for insertion of 180 mg in 590 women was 3.9% compared to 1.9% for the 160 who received 252 mg. There were no serious complications, and side effects were transient. We conclude that quinacrine non-surgical sterilization is a safe, acceptably effective method when two insertions of 252 mg quinacrine with medroxyprogesterone injection as a supplement is used.

Mid-arm circumference at birth as predictor of low birth weight and neonatal mortality.

In Bangladesh, like other developing countries, most births occur at home or in the community, so logistic problems and taboos prevent the weighing of every newborn child. This study was performed to see whether other simpler measurements could be substituted for weight to identify neonates of low birth weight. A total of 1676 live births at the Chittagong Medical College Hospital constituted the study sample, and this showed a high correlation between mid-arm circumference and birth weight (r=0.792, p<0.000). A mid-arm circumference of <9.0 cm had the best sensitivity and specificity for identifying newborns with a birth weight of less than 2500 g. These neonates were followed up to record neonatal deaths. Neonatal mortality showed an inverse relation with mid-arm circumference. A mid-arm circumference of <9.0 cm and a birth weight of <2500 g were equally useful in predicting neonatal outcome. Mid-arm circumference is a simple, quick and reliable indicator for predicting low birth weight and neonatal outcome, and can be easily measured by medical practitioners and traditional birth attendants (TBAs) in the community of developing countries like Bangladesh.

Maternal and public health benefits of menstrual regulation in Chittagong.

In Bangladesh abortions induced by untrained traditional birth attendants cause high levels of morbidity and mortality. A 2-year program was initiated to provide early atraumatic termination of pregnancy at Chittagong Medical College Hospital on an outpatient basis. The effect of the program on hospital admissions for septic induced abortion was studied by reviewing hospital records. In 2 years hospital admission for induced abortion decreased by 72%, and bed days used for treatment of induced abortion declined by 75%. Deaths occurring in the hospital that were attributed to induced abortion remained at a low level but were not eliminated.
