ABSTRACT

BACKGROUND: Sickle cell disease (SCD) is a hemoglobin disorders that concern 300,000 newborns each year around the world. There are hemoglobin haplotypes that affect SCD clinic expression. METHODS: Our goal was to identify the hemoglobin's haplotypes among individuals with mild malaria independently of SCD status in Côte d'Ivoire. To determine these haplotypes, specific restriction enzyme (RE) is used after PCR amplification with each primer. According to the digestion of PCR product by RE, five hemoglobin's haplotypes are found in the world. RESULTS: In Côte d'Ivoire, no study has yet deeply described the distribution of haplotypes. Four different "classical" haplotypes of hemoglobin were detected: Benin (56.5%), Bantou (28.5%), Senegal (4%), Cameroun (1%); and 10% of atypical profiles. Heterozygous haplotype (69%) were more frequent than homozygous haplotype (31%). CONCLUSIONS: In this preliminary study, we note a high prevalence of atypical and heterozygous haplotype. Benin haplotype that is associated with severity of SCD was most predominant in our studied population.

ABSTRACT

Introduction. En Cote d'Ivoire; le depistage systematique de l'hypothyroidie ne fait pas encore partie des directives nationales du ministere de la sante. Aussi; l'hypothyroidie est decouverte souvent tardivement au stade des complications. L'objectif de ce travail etait de decrire les principales caracteristiques epidemiologiques; diagnostiques; therapeutiques et evolutives de l'hypothyroidie congenital Population et methode. Nous rapportons l'observation du nourrisson D.Z; age de 14 mois; admis en pediatrie au CHU de Bouake en novembre 2013 pour un retard de croissance et de developpement psychomoteur. Les antecedents pre et per-nataux etaient sans particularite. En periode neonatale; le nourrisson etait mou; dormait beaucoup; avait une respiration bruyante et une constipation. Par la suite il s'est installe un retard psychomoteur et de croissance d'aggravation progressive sans fievre. A 6 mois; le nourrisson ne tenait pas la tete dans l'axe; n'avait pas de poursuite oculaire; ne reconnaissait pas sa mere; ne repondait pas aux sourires et sa croissance semblait ralentie. A 14 mois; D.Z etait devenu plus hypotonique; sa respiration toujours bruyante; ne s'asseyait toujours pas et ne repetait aucunes syllabes. En revanche il suivait du regard; entendait et avait acquis le sourire-reponse. Plusieurs medications traditionnelles et modernes ont ete entreprises sans succes. Les investigations para cliniques ont permis de retenir le diagnostic d'une hypothyroidie congenital. Conclusion. Les signes de l'hypothyroidie congenitale; au debut; sont frustres et egarent le diagnostic. Une collaboration multidisciplinaire incluant le gynecologue obstetricien; le pediatre et l'endocrinologue est indispensable pour le diagnostic precoce et la prise en charge adaptee afin d'eviter la regression psychomotrice prejudiciable a l'enfant

ABSTRACT

To determine whether apparent involvement of DYRK1A in Alzheimer's disease (AD) pathology makes it a candidate plasma biomarker for diagnosis, we developed a method to quantify plasma DYRK1A by immunoblot in transgenic mouse models having different gene dosages of Dyrk1a, and, consequently, different relative protein expression. Then, we measured plasma DYRK1A levels in 26 patients with biologically confirmed AD and 25 controls (negative amyloid imaging available on 13). DYRK1A was detected in transgenic mouse brain and plasma samples, and relative levels of DYRK1A correlated with the gene copy number. In plasma from AD patients, DYRK1A levels were significantly lower compared with controls (P<0.0001). Results were similar when we compared AD patients with the subgroup of controls confirmed by negative amyloid imaging. In a subgroup of patients with early AD (CDR=0.5), lower DYRK1A expression was confirmed. In contrast, no difference was found in levels of DYRK1B, the closest relative of DYRK1A, between AD patients and controls. Further, AD patients exhibited a positive correlation between plasma DYRK1A levels and cerebrospinal fluid tau and phosphorylated-tau proteins, but no correlation with amyloid-ß42 levels and Pittsburgh compound B cortical binding. DYRK1A levels detected in lymphoblastoid cell lines from AD patients were also lower when compared with cells from age-matched controls. These findings suggest that reduced DYRK1A expression might be a novel plasma risk factor for AD.

ABSTRACT

Contexte : Les douleurs abdominales aigues (DAA) posent en urgence un probleme diagnostique et prise en charge therapeutique. Les causes medicales n'ont pas encore ete precisees chez l'enfant a Bouake. Objectif : Identifier les principales etiologies de la DAA de l'enfant Patients et methodes : Il s'agit d'une etude retrospective et descriptive realisee au CHU de Bouake du 1 er janvier au 31 decembre 2012. Elle a inclus 90 enfants ages de 2 a 14 ans hospitalises pour DAA. Les parametres d'etudes etaient epidemiologiques et diagnostiques. Resultats : Les 90 cas de DAA ont ete retenus parmi 3677 admissions soit 2;5 . Le sexe ratio etait de 0;95 et l'age median de 72 mois (24-168 mois). La tranche d'age 60-119 mois representait 46;5. Le delai avant la consultation etait superieur a 48 heures dans 63;1. Les principaux signes fonctionnels associes etaient la fievre 86;7; les vomissements 62;2; l'anorexie 50; l'asthenie 37;7; le trouble de la conscience 20 et les convulsions 15;5. Les principaux signes physiques etaient la fievre 67;7; l'anemie 63;4 ; la splenomegalie 23;6; le coma 19 et le tirage intercostal 11;8 . Le paludisme (62;1); la drepanocytose (6;6); la pneumonie (5;7); la fievre typhoide (5;5) et la gastroenterite (4;4) etaient les principales causes. Conclusion : Les principales causes medicales des DAA de l'enfant sont le paludisme; la drepanocytose et la pneumonie. L'amelioration du pronostic des DAA necessite le controle de ses principales causes

ABSTRACT

Class I malocclusion with severe dental crowding can constitute a serious psychosocial and functional damage among young patients; from where orthodontic importance of the treatment. In the present study the authors present the treatment of two clinical cases whose initial problems are similar. They are two cases of class I malocclusion but whose certain diagnosed clinical factors have constrained in a case to control to the maximum anchoring on the level of the molars and in the other to control the dental axes. The final results are satisfactory because of the restoration of a physiological occlusion. Concomitantly we obtain a clear improvement of the smile.

ABSTRACT

In dentofacial orthopedics, rehabilitation concerns the performance of the orofacial functions. Orthodontists will therefore speak of rehabilitation of functions, or functional therapy. Orofacial functions seem to obey a hierarchical system in accordance with their physiological importance; the impact of their disorders on both muscular behavior and facial morphogenesis, proportionally to their physiological importance. Therefore, priority will be given at a very early stage to the rehabilitation of respiration: restoring nasal ventilation is indeed an essential condition to obtain balanced oral functions because oral ventilation conditions both muscular posture and the performance of other functions. A little later, affective immaturity symptoms closely linked to various persisting bad suction habits will be looked after. At last, the rehabilitation of phonation and chewing both affected by the previous dysfunctions will participate in acquiring correct lingual position. The age for intervention will before all depend on the dysfunctional etiopathogeny. The morphological context, the importance of the malocclusion, and some orthodontic appliances also play a role in the the dysfunctional requests and the alterations of oral behavior.

ABSTRACT

Nowadays aesthetic standards reflect a generalisation of western ones. We propose to outline an aesthetic concept about Ivorian face. A selected jury will have to judge fifty-three Ivorian faces, through photographs and also, we'll make the cephalometric analysis of flabby and osseous tissues. We expect then, to provide orthodontists with basic references whenever they have to establish treatment objectives, for Negro-African, (particularly Ivorian), patients with facial disharmony evaluated according to western norms.
