ABSTRACT
INTRODUCTION: In recent times, there has been an increase in the frequency of hypertension among young people which is contributing globally to the increase in cardiovascular morbidity and mortality in adults. OBJECTIVE: The aim of this study was therefore to determine the prevalence of primary hypertension and its risk factors among apparently healthy secondary school students in Osogbo, southwestern Nigeria. METHODS: A school-based cross-sectional study of a total of 404 secondary school students in Osogbo city. Following informed parental consents of all the students involved in the study, blood pressure (BP) measurements were taken at 2 different visits by auscultation after a negative urine dip stick test result (thus excluding haematuria or proteinuria) in every subject before each BP was measured. RESULTS: The overall prevalence of hypertension and prehypertension in this study was 3.5% (n = 14) and 6.2% (n = 25), respectively. Obesity, consumption of extra - uncooked salt, high parental education and attendance of privately-owned secondary schools were identified risk factors associated with elevated BP. Seven (29%) of 24 subjects with hypertension had features of left ventricular hypertrophy (an evidence of target organ damage) on echocardiography and electrocardiography. All subjects with elevated BP had normal renal scan. CONCLUSION: Hypertension with features of target organ damage exists among adolescents. No known primary aetiologies were found among the hypertensive adolescents in the study and thus they were all deemed to have essential hypertension.
INTRODUCTION: Ces derniers temps, on a constaté une augmentation de la fréquence de l'hypertension chez les jeunes, ce qui contribue globalement à l'augmentation de la morbidité et de la mortalité cardiovasculaires chez les adultes. OBJECTIF: Le but de cette étude était donc de déterminer la prévalence de l'hypertension primaire et de ses facteurs de risque parmi des élèves du secondaire apparemment en bonne santé à Osogbo, sud-ouest du Nigeria. MÉTHODES: Étude transversale en milieu scolaire portant sur un total de 404 élèves du secondaire dans la ville d'Osogbo. Après avoir obtenu le parents informés de tous les élèves participant à l'étude, des mesures de l'étude, la pression artérielle a été mesurée par auscultation lors de 2 visites après un résultat négatif à la bandelette urinaire (excluant ainsi l'hématurie ou la protéinurie) chez chaque sujet avant que la TA ne soit mesurée. RÉSULTATS: La prévalence globale de l'hypertension et de la préhypertension dans cette étude était de 3,5% (n = 14) et de 6,2% (n = 25), respectivement. L'obésité, la consommation de sel extra-cuit, le haut niveau d'éducation des parents et la fréquentation d'écoles secondaires privées ont été identifiés comme des facteurs de risque associés à une tension artérielle élevée. Sept (29%) des 24 sujets hypertendus présentaient des caractéristiques d'hypertrophie du ventriculaire gauche (preuve d'une atteinte des organes cibles) à l'échocardiographie et à l'électrocardiographie. Tous les sujets présentant une PA élevée avaient une scintigraphie rénale normale. CONCLUSION: L'hypertension avec des caractéristiques d'atteinte des organes cibles existe chez les adolescents. Aucune étiologie primaire connue n'a été trouvée chez les adolescents hypertendus de l'étude et donc tous considérés comme souffrant d'hypertension essentielle. Mots clés: Hypertension primaire, dommages aux organes cibles, adolescents sains.

A case ofiatrogenic thermal injury in a newborn infant during resuscitation for perinatal asphyxia at a secondary health facility is described. The injury, with surface area coverage of about 4%, involved the lower limbs. This report highlights the poor newborn resuscitation skills of traditional medical practice.

This study was conducted in 124 children with meningitis to review the etiology, antimicrobial susceptibility and outcome of disease in a Nigerian tertiary health facility. Of these, 97 (78.27%) were culture positive; in the rest 27(21.8%), diagnosis was based on Gram staining of the CSF. Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus and Escherichia coli were isolated in 33.9%, 33.9%, 5.6%, 2.4%, and 2.4% samples respectively. All the isolates had 100 percent; sensitivity to both ceftriaxone and ciprofloxacin while the sensitivities to penicillin and ampicillin were remarkably low. The mortality was 33/124 (26.6%) while 16/ 91 (17.6%) of the survivors had various neurologic sequelae.
