Knowledge, attitude, practice, and prescribing pattern of oral rehydration therapy among private practitioners in Nigeria.
To determine the knowledge, attitude, and practice of oral rehydration therapy (ORT) among private medical practitioners in Enugu, Nigeria, 91 doctors were interviewed using a structured questionnaire. All the doctors had heard of ORT and believed in its efficacy. The commonest source of information on ORT was the medical school (44%). ⋯ Antibiotics were commonly used, although most (76%) doctors believed that viral infections were a common cause of childhood diarrhoea. All the respondents would recommend continued breastfeeding during diarrhoeal episodes. The study revealed a high rate of inappropriate drug use and a deficiency in the knowledge and practice of ORT.

Long-term administration of morphine for the treatment of chronic pain produces constipation; this requires the use of laxatives, which impair water absorption and upset the electrolyte balance. Morphine-induced constipation is mainly due to inhibition of the propulsive movement of the gastrointestinal tract combined with spastic contraction of smooth circular muscles as a result of drug binding to opioid receptors in the tract. Since papaverine lacks affinity for opioid receptors but relaxes smooth muscle, it seemed possible that oral papaverine might be capable of diminishing constipation without impairing the analgesia achieved with morphine. ⋯ Since in former experiments on nociceptive activity evoked in thalamus neurones it has been found that the ED(50) of i. v. morphine is 0.05 mg/kg, it is very likely that the presystemic elimination of orally administered morphine is very high and, in addition, that the efficiency of its active metabolite, morphine-6-glucuronide, is rather poor. When morphine 2.5 mg/kg was given together with papaverine 0.5 mg/kg, and morphine 5 mg/kg was administered in combination with papaverine 2 mg/kg, there was no significant reduction in the depressant effect of morphine on nociceptive activity evoked in thalamus neurons (Figs. 6, 7). The results suggest that papaverine given by the oral route may reduce morphine-induced constipation without impairment of the analgesic action of morphine in patients suffering from pain.

[Increasing use of cesarean section, even in developing countries].
At Kaziba hospital in rural Zaire, the frequency of deliveries by Caesarean section rose from 6.2% in 1971 to 12% in 1992, and the fraction of repeated sections rose from 17% to 49%. During the same period, the overall maternal mortality decreased from 0.3% to 0.12%, and deaths connected with Caesarean section from 3.2% to 0.7%, but still the risk of dying remained 13 times higher for births by Caesarean section compared with vaginal deliveries. The frequency of vacuum deliveries was halved during the period, and mean birth weight decreased by about 100 g. ⋯ Operations carried out by persons other than physicians were complicated by wound infections at a higher rate (20.8%) than those carried out by experienced doctors (11.2%). In areas with a poorly developed health system, a high rate of Caesarean section represents a hazard to maternal health. The need for knowledge about alternative methods like vaginal extraction, symphyseotomy and active management of labour is underlined.

Randomized Controlled Trial Comparative Study Clinical TrialA double-blind clinical trial comparing World Health Organization oral rehydration solution with a reduced osmolarity solution containing equal amounts of sodium and glucose.
To compare the safety and efficacy of an oral rehydration solution (ORS) containing 75 mmol/L of sodium and glucose each with the standard World Health Organization (WHO) ORS among Egyptian children with acute diarrhea. ⋯ The reduced osmolarity ORS has beneficial effects on the clinical course of acute diarrhea in children by reducing stool output, and the proportion of children with vomiting during the rehydration phase, and by reducing the need for supplemental intravenous therapy. These results provide support for the use of a reduced osmolarity ORS in children with acute noncholera diarrhea.

Comparative Study Clinical Trial Controlled Clinical TrialMalaria parasite infection during pregnancy and at delivery in mother, placenta, and newborn: efficacy of chloroquine and mefloquine in rural Malawi.
Despite international recommendations to use malaria treatment and prevention in pregnant women in malaria-endemic areas, few studies have evaluated the efficacy of available antimalarial regimens. This issue is of particular concern in the face of spreading chloroquine (CQ)-resistance of Plasmodium falciparum in malarious areas of sub-Saharan Africa. In a prospective trial in rural Malawian pregnant women, we examined three regimens using CQ (including the existing national policy regimen) and one regimen using mefloquine (MQ). ⋯ Maternal anemia (hematocrit < 30%) at enrollment or at delivery was not associated with persistent or breakthrough parasitemia or parasitemia at deliver in these multivariate models. While factors leading to increased malaria parasite exposure (high transmission seasons) and lowered or altered host immune response (low pregnancy number, young age, and HIV infection) are important risk factors for malaria in pregnant women, the use of an ineffective intervention (CQ in a setting with CQ-resistant parasites) was the most important determinant of P. falciparum parasitemia in these pregnant women. Strategies to reduce the impact of malaria in pregnant women must use efficacious interventions and may need to consider targeting the intervention to the most susceptible women during the seasons of high malaria exposure.
