ABSTRACT
Le paludisme reste un problème majeur de santé publique en Afrique subsaharienne, notamment au Niger où il sévit sur un mode endémique. Un des éléments de gravité est la survenue d'une hémoglobinurie et/ou une anémie. Nous rapportons 5 observations d'anémie par déficit en glucose-6-phosphatase (G6PD) de diagnostic tardif, car mis dans le compte du paludisme grave. Il s'agissait de cinq enfants d'âge moyen de 8,2 ans. 3 des patients étaient de sexe masculin. Tous les cinq patients étaient admis en urgence, référés pour anémie sévère dans un contexte de fièvre. Le nombre moyen d'hospitalisations antérieures était de 4. Les principaux signes à l'admission étaient la pâleur, les douleurs abdominales et des urines couleur porto. La bandelette urinaire a révélé une hémoglobinurie chez tous les patients et une bilirubinurie dans 4 cas. Une notion d'ictère a été retrouvée chez 2 patients, les 3 autres présentaient un ictère clinique. Le taux d'hémoglobine moyen était de 4,4 g/dl. Le taux des plaquettes et le taux de réticulocytes étaient normaux. La goutte épaisse était positive chez tous les patients. Le profil électrophorétique de l'hémoglobine était hétérozygote AS dans 2 cas et homozygote AA dans 3 cas. L'activité enzymatique de la G6PD, dosée à distance de la crise, était effondrée chez tous les patients. Le déficit en G6PD constituant une cause fréquente d'hémoglobinurie et/ou d'anémie chez l'enfant, le bilan étiologique, surtout devant la récurrence de ces signes, devrait en outre comporter un dosage de l'activité enzymatique de la G6PD

La leucémie aiguë lymphoblastique (LAL) néonatale est une affection exceptionnelle et est de mauvais pronostic. Nous décrivons l'observation d'un nouveau-né à Jo de vie, atteint d'une LAL de type B, révélée par un syndrome hémorragique et tumoral en service de réanimation néonatale du CHU Hassan II de Fès, dont l'évolution a été marqué après 25 jours de vie par le décès du patient dans un tableau de lyse tumoral, quelques jours après une chimiothérapie d'induction

Objective: This study was designed to evaluate the effect of Typhoid fever on the serum levels of electrolytes in patients attending Minna General Hospital, Nigeria. Materials and Methods: Blood samples were obtained from sixty patients with established typhoid fever attending General Hospital Minna, Nigeria. Serum sodium, potassium, chloride, and bicarbonate levels were determined in the samples using Spectrophotometric method. The case studies included 15 adult males and 15 adult females; 15 male and 15 female children of junior secondary school age (9 – 14 years). Widal test was carried out to ascertain the presence of Salmonella enterica serotype Typhi. Results: The mean ± standard deviations of serum Na+, K+, Cl-, and HCO3- in the sixty patients were 116.11±20.65 mmol/L; 3.40±0.90 mmol/L; 87.13±16.34 mmol/L; and 24.10±5.54 mmol/L respectively. When compared with the controls and the laboratory reported normal values, 50% of the patients were found to be hyponatraemic, 51% were hypochloraemic, 36% were hypokalaemic, while 11% had metabolic acidosis. Results based on sex showed insignificant differences between males and females for all electrolytes determined (p< 0.05). Insignificant differences were also observed between children and adult patients for all parameters determined (p< 0.05). In addition, weak positive correlations were observed between cations and anions determined in this study. Conclusion: The results obtained in this study showed that electrolytes’ abnormalities exist in patients with established typhoid fever attending General Hospital Minna, Niger state, Nigeria.
ABSTRACT
Background: Traditional and complimentary health care is inarguably the system most close to homes, accessible and affordable. It is also culturally acceptable and trusted by large numbers of people. The affordability of most traditional medicines makes them all the more attractive at a time of soaring health-care costs, neglect of orphaned/non profitable diseases and nearly universal austerity. Aim: Aqueous leaf, stem bark and root bark extracts were evaluated for their anti trypanosomal effect in experimental trypanosomiasis with a view to come up with a phytomedicine that is efficacious, available, accessible and non-toxic to both humans and animals. Study Design: Complete randomized clinical trial design was used in the experiment. Methodology: Ninety five (95) mice were grouped into three (I, II, III) of thirty mice each (with sub groups A, B, C, D, E, and F consisting of five mice each) to which the leaf, stem bark and root bark extracts were administered at a dose of 100, 200, 300, 400 mg/Kgbw, while the remaining five mice served as the control for all the groups. Results: The aqueous leaves extract at doses of 100, 200 and 300 mg/Kg bw portrayed very low activities except for the 400 mg/Kg bw that displayed a sustained Trypanostatic effect. The aqueous stem bark extract, at doses of 100 and 200 mg/Kg bw portrayed trypanostatic effect while doses of 300 and 400 mg/Kg bw effectively cleared the parasites from circulation on the 13th and 17th days into the treatment respectively. Three and two of treated mice survived and remained apparasitaemic for up to 120 days and beyond in the group treated with 300 and 400 mg/kg bw respectively. In the group treated with the root bark extract, the mice on a dose of 100 mg/Kg bw died some few days into the experiment (6th day) while the dose of 200 mg/Kgbw sustained the animals until the 19th day. Doses of 300 and 400 mg/Kg bw were observed to clear the parasites in circulation after sustained administration for 23 and 16 days respectively. Conclusion: This study has demonstrated the potency of the stem bark and root bark crude extracts of Afzelia africana in treating experimental trypanosomiasis and can thus be further purified and packaged as phytomedicine against this dreaded but neglected disease.
ABSTRACT
Crossopteryx febrifuga is one of the useful plants used in Hausa traditional medicine in North Western Nigeria. It belongs to the family Rubiaceae. The phytochemical studies of the root bark of the plant was carried out using standard procedure. The was found tocontain: steroids, flavonoids, terpenoids, anthraquinones, cardiac glycosides, tannins, alkaloids and saponnins. The antimicrobial activity screening was carried out using both bacterial and fungal strains. The bacterial strains include: Pseudomonas aeruginosa, Staphylococcus aureus, Eschericia coli. The fungal strains Include: Aspergillus fumigatus, Candida albicans, Aspergillus flavus and Aspergillus niger. In general, the extract showed considerable activity on the bacterial species. It inhibited the growth of both gram positive and gram negative microorganism with zones of inhibition ranging from 7- 23 mm at concentrations of 50 μg/ml, 100 μg/ml and 200 μg/ml. The plant extract did not show significant activity on fungal strains. It inhibited the growth of Aspergillus fumigatus at 400 μg/ml and 500 μg/ml which produced zones of inhibition of 8 mm and 12 mm respectively at the stated concentration. It can be concluded that the activity showed by the methanolic extract of the plant is as a result of the phytochemicals present in the plant.
ABSTRACT
La malnutrition est aggravee par les deficiences en oligo-elements et l'une des formes les plus connues est la carence en iode qui donne des troubles divers. Cette carence atteint environ 160 millions de personnes en Afrique contre 300 millions en Chine; 200 millions en Inde; 100 millions en Indinesie; 60 millions en Amerique et quelques millions de cas en Europe. Les troubles dus a la carence en iode (TDCI) sont un probleme general qui touche 12de la population mondiale. Au Cameroun; l'enquete nationale sur les TDCI montre que 6 millions de personnes sur 11 millions sont atteintes; de meme que toutes les 10 provinces mais a des taux differentes de prevalence. Ainsi une forte endemicite est signalee a l'Extreme-Nord (Doukoula 75); au Nord-Ouest (64a Oshie et 59a Jakiri); dans l'Adamaoua (45dans Vina); dans Ouest (58dans le Noun) et une endemicite moindre dans l'Est (14a Batouri)
