RESUMEN
The intramuscular (i.m.) route is generally used for treatment of childhood falciparum malaria in outlying health care units in Togo. The purpose of this randomized therapeutic trial was to compare the efficacy and tolerance of diluted injectable quinine administered by the i.m. versus intrarectal (IR) route. A total of 64 children ranging in age from 8 months to 15 years were treated, i.e. 32 for each administration route. All children presented uncomplicated falciparum malaria in association with vomiting in 30 cases, a single unrecurring seizure with postictal coma lasting less than 30 minutes in 25 patients, or prostration without neurological manifestations in 9. Injectable quinimax (an association of cinchona alkaloids) was diluted to a concentration of 60 mg base/ml for i.m. injection into the thigh and 30 mg base/ml for use by the IR route. Administration was performed every 12 hours for 72 hours at a dose of 12.5 mg/kg for patients in the i.m. group or at a dose of 15 mg/kg in the IR group. The anus and lower rectal mucosa were examined using an anal valve before and after treatment using the IR route. Analysis of mean temperature curves demonstrated no significant difference between the clinical effectiveness of quinimax administered by the i.m. versus IR route (p > 0.05). Similar effect were also observed on parasitemia which disappeared completely in all patients by the end of the 72-hour treatment. The main problems were insufficient product retention requiring re-administration in 25% of patients in IR group and residual pain at the injection site in 12.5% of patients in the i.m. group. Endoscopic examination revealed no evidence of ulceration or necrosis of the anorectal mucosa. These findings indicate that administration of diluted injectable quinine by IR route is an effective, well-tolerated alternative for treatment of childhood falciparum malaria. It should be used preferentially in outlying health care units in patients presenting severe malaria pending transfer to an hospital, or signs of "intermediate severity" such as hyperpyrexia, hyperparasitemia, unrepeated seizure, or intensive vomiting.

OBJECTIVE: To compare in a randomized study the efficacy and the toxicity of the new WHO intravenous quinine treatment of cerebral malaria including a loading dose regimen to a regimen without loading dose. PATIENTS AND METHODS: Seventy-two children eight months to 15 years of age with cerebral malaria were included. Quinine formiate was administered to a group of 35 patients in an initial loading dose of 20 mg salt/kg (equivalent to 17.5 mg/kg of the base) in 10 mL/kg of 5% glucose over four hours, followed eight hours later by a maintenance dose quinine of 10 mg salt/kg (equivalent to 8.7 mg/kg of the base) dissolved in 15 mL/kg of 5% glucose over and every 12 hours. The second group of 37 patients received intravenous quinine 15 mg salt/kg (13.1 mg of base) dissolved in 15 mL/kg of 5% glucose infused over 6 to 8 hours, every 12 hours. In both groups this treatment was continued until the patient could swallow, then quinine tablets were given to complete seven days treatment. The assessment of cardiovascular side effects was made by an ECG at admission, the 4th hour, the 24th hour and at the end of treatment for each patient. RESULTS: Coma mean durations were similar in the two groups: 35.5 +/- 17.8 hours and 28.6 +/- 14.4 hours respectively for the loading dose group and the group without loading dose. The two groups were comparable also for the decrease evolution of parasitemia. Case-fatality rates were also similar: 95% of healing at the 72nd hour and a lethality rate between 5 and 6% in the two groups. But a significant increase of the body temperature was noted between the 51st and the 63rd hour in the group without loading dose. No significant cardiovascular toxicity was noticed in the two groups. The mean cost of the loading dose regimen was less than that of the second regimen. CONCLUSION: The loading dose regimen of quinine is well tolerated and it seemed slightly more effective than the regimen without loading dose. In cases of contra-indications (patients who recently received quinine, mefloquine or halofantrine), regimens without loading dose, which remains effective, should be used.

BACKGROUND: Mid-upper-arm circumference (MUAC) is widely used as a nutritional status index for children. The aim of our study was to construct MUAC-for-age curves for well-fed 1-36-month-old children of a developing country and to compare them with the WHO reference charts based on samples of American children. POPULATION AND METHODS: Five thousand thirty-eight boys and 4,972 girls aged 1-36 months were recruited cross-sectionally from 1994 to 1997. Their MUAC were measured as recommended by the WHO. To develop the curves, estimations were first obtained for the mean and standard deviation (SD) of MUAC for each month of age using a 7-month segmental regression equation; the Count model and 2nd degree polynomial in age were then used to describe the mean and SD respectively. RESULTS: These curves showed important differences for age and sex and were lower than the reference curves, particularly for the older children. The mean curve was -0.44 to -0.75 SD for boys and 0 to -0.8 SD for girls, far from the WHO's reference. CONCLUSIONS: The authors proposed to take into account the WHO's nutritional recommendations and developing country features in the construction of the reference charts.

Intracavernous injections of etilefrine were effective in seven children with acute sickle cell priapism, and stuttering priapism resolved in five children after one to seven months of oral etilefrine. Compared with our previous reports in adults, etilefrine appears to be more effective in childhood.

Prevalence of priapism and knowledge on this disease was assessed by interviewing a group of 114 sickle cell anemia patients, 5 years and older, considered to be genotypically homogenous (Benin or #19 haplotype). Prevalence of priapism in homozygous sickle cell patients was 26.3% (30/114) and that of the control group of subjects with Hb AA was 2% (2/102) (the difference was very significant: p = 5.10-7). Actuarial probability of having priapism by 20 years of age was 69 +/- 8.5%. Few homozygous patients without a history of priapism (15.8%) have heard about priapism. This lack of knowledge, added to low accessibility of a health care system, may explain the high rate of impotence (31.6%). The results of this study led us to plan a large program of infonnation about priapism and sickle cell disease in the Togolese population.

Two cross-sectional studies were carried out in the pediatric ward of the Tokoin Teaching Hospital, Lome. One study determined the prevalence of HIV infection in the 49 malnourished patients treated in the ward in February to March and between August and December 1994. The other was carried out between July 1994 and January 1995 and included 57 other hospitalized children fulfilling at least one of the WHO's pediatric AIDS criteria. The aim was to draw up a screening system for pediatric AIDS based on clinical scores that would be more sensitive than and as specific as the WHO criteria. We tested these criteria and the other signs used in the suggested scoring system using the reference test, HIVchek. The seroprevalence of HIV was 28.6% in malnourished children and transmission was probably exclusively from mother to child. It was difficult to distinguish pediatric AIDS from protein energy malnutrition on clinical grounds, although some of the associated morbidities, including anemia, adenopathy and splenomegaly, were highly suggestive of pediatric AIDS. The second study showed that: 1) the sensitivity of the WHO criteria was low; 2) the best positive predictive values were obtained in cases of polyadenopathy and confirmed HIV infection of the mother. Both these criteria were relatively infrequent; 3) there were 6 criteria significantly associated with HIV infection, each being given a point score according to its Yule coefficient: chronic cough (4 points), chronic diarrhea (3 points), chronic fever (2 points), oropharyngeal candidiasis (2 points) and marasmus (1 point). A score of 4 points was the threshold for suspicion of pediatric AIDS. Our scoring system was more sensitive than the WHO criteria and had similar specificity and positive predictive value. We stress the importance of preventive measures against HIV infection, particularly for women of child-bearing age and suggest a new score test and appropriate clinical definitions for infants and older children.
