Evaluation of Malnutrition among Children Aged 2 to 60 Months Hospitalized in the Pediatric Services of Ziguinchor Hospital

Introduction: Malnutrition is a public health problem in the world and especially in developing countries. The prevalence of malnutrition at the national level does not reflect the situation in hospital. It is in this context that we assessed the nutritional status of children under 5 years old hospitalized pediatric services in the municipality of Ziguinchor. Material and methods: This was a prospective study that ran from June 1 to October 30, 2016. Included were children aged 2 to 60 months hospitalized in one of the two services. Children with esdato-ascetic syndrome were not included. Epidemiological, anthropometric data, and associated diagnosis were studied. Results: We included 114 children (70 boys and 44 girls). The average age was 21.9 months. Forty-two point one percent (42.1%) of infants <6 months were breastfed exclusively with breast milk. The weaning of children is done early in 55.3%. The mean age of mothers was 26.6 years. The socioeconomic level was low in 62.3% of cases. The prevalence of malnutrition averaged 35.5% for underweight; 32.9% for wasting and 32.0% for stunting. Acute respiratory infections (ARI) and acute gastroenteritis were the most common associated conditions. Mean hospital stay was 8 days ± 009. About two thirds of the patients (n=72) had a hospital stay of more than 7 days. Malnutrition was significantly associated with multiparity, low socioeconomic status, hospital stay of more than 7 days and infectious diseases. Conclusion: Infections and hospitalization lasting more than a week are factors that promote malnutrition in children under 5 years of age.

Profils épidemiologiques, cliniques et hématologiques de la drépanocytose homozygote SS en phase inter critique chez l’enfant à Ziguinchor, Sénégal

Sickle cell disease poses a public health problem in Senegal. It mainly affects children and adolescents. This study aimed to determine the epidemiological, clinical and hematological profiles of homozygous (SS) sickle cell disease in a cohort of children followed-up at the Peace Hospital in Ziguinchor. We conducted a retrospective study of the medical records from children with sickle cell disease. All patients aged between 2 months and 21 years with sickle cell disease SS during the intercritical period, hospitalized during the study period from 1st January 2015 to 31 August 2017 were included in our study. Compound heterozygous patients (SC, S Beta Thalassemia) were not included. We collected 46 medical records of patients with sickle cell disease SS (20 girls and 26 boys). The average age of children was 8,0 years [11 months-21 years]. Approximately 1/3 of children (39.1%) had an age less than or equal to 5 years. There was an ethnic diversity showing a predominance of the Diola (30.2%) followed by the Mandinga (27.9%) and the Poular (25.6%). The average age of children with first crisis was 35,5 months [7-192 months]. More than 1/3 of children (41.3%) had had first crisis before their second anniversary. In the child, first crisis was dominated by vaso-occlusive crisis (32.6%) followed by hand-foot syndrome (30.4%). Clinical signs during the intercritical period were pallor 95.6%), jaundice (36.9%) and splenomegaly (21.7%). Mean white blood cell count was 12465 leucocytes/mm3 [5340-26900]. Hyperleukocytosis greater than 10 000 leucocytes/mm3was found in 34 patients (73.9%). All patients had anemia with an average hemoglobin of 08,6 g/dl [05,7-11,8]. Hemoglobin S rate ranged between 54.6 and 98.4%. Diagnosis and medical management of sickle cell disease SS are delayed in Ziguinchor. Neonatal screening may lead to improve early management of patients in the region.

Le syndrome néphrotique idiopathique (SNI) de l’enfant à Dakar: à propos de 40 cas

Introduction L’objectif de ce travail était d’analyser les caractéristiques diagnostiques, thérapeutiques et évolutives de l’enfant atteint de néphrose dans un service de pédiatrie de Dakar. Méthodes L’étude était réalisée au service de pédiatrie de l’hôpital Aristide Le Dantec. Il s’agissait d’une étude rétrospective sur une période de 03 ans allant du 1er janvier 2012 au 31 décembre 2014. Ont été inclus tous les patients âgés de 02 ans à 12 ans présentant un tableau de Syndrome néphrotique idiopathique. Résultats Quarante cas de néphrose étaient colligés soit une prévalence de 23% parmi les néphropathies prises en charge dans le service. L’âge moyen était de 7,11± 3,14 ans. Le syndrome néphrotique était pur chez 72,5% (n=29) des patients. Les œdèmes des membres inférieurs étaient présents chez 100% des patients, l’oligurie dans 55% (n=22) et l’HTA dans 5% (n=2) des cas. La protéinurie moyenne était de 145,05 ± 85,54 mg/kg/24heures. La protidémie moyenne était de 46,42 ±7,88 g/L et l’albuminémie moyenne de 17,90 ± 7,15 g/L. Trente-neuf patients avaient reçu une corticothérapie à base de prednisone. La corticosensibilité était retenue chez 77% (n=30) des patients et la corticorésistance chez 13% (n=5) des cas. Le facteur de mauvaise réponse à la corticothérapie était un niveau de protéinurie initiale supérieure à 150 mg/kg/jour (p = 0,024). La biopsie rénale était réalisée chez 18% (n=7) des patients et retrouvait dans 57,2% (n=4) des cas une hyalinose segmentaire et focale. Le cyclophosphamide et l’azathioprine étaient associés aux corticoïdes dans 10% (n=4) des cas chacun. Le taux de rémission globale était de 89,8%. L’évolution vers l’insuffisance rénale chronique était notée chez trois (03) des patients. Conclusion La néphrose représentait près du quart des néphropathies prises en charge dans notre service. Le taux de rémission globale était élevé. Le seul facteur de mauvaise réponse à la corticothérapie était le niveau de protéinurie initiale élevée. En cas d’indication de la biopsie rénale chez nos patients, la HSF était la lésion la plus fréquemment retrouvée.

Syndrome hémolytique et urémique de l'enfant au Centre Hospitalier Universitaire (CHU) de Dakar: à propos de quatre observations

Hemolytic-uremic syndrome (HUS) is a common cause of organic acute renal failure (ARF) in children. It is a progressive complication of acute gastroenteritis (AGE), especially caused by Escherichia coli in children. This study aimed to describe the clinical, therapeutic and evolutionary aspects of this affection in four children. We collected four cases of HUS. The average age was 10,5 months (5-15mois), exclusively boys. Clinical examination revealed a hemolytic anemia (pallor and jaundice), oligoanuria and edematous syndrome (2 cases), arterial hypertension (1 patient), AGE associated with severe dehydration and hypovolemic shock (2 patients), consciousness disorders. ARF was found in all patients as well as thrombocytopenia and schizocytes smear. Direct Coombs test was negative. Hyperkalemia was found in 3 patients, of whom 1 with hyperkalemia level of more than 9.2 mmol/L, hyponatremia at 129 mmol/l (1 patient) and hypernatremia at 153 mmol/l (1 patient). HUS was secondary to pneumococcal pneumonia (1 patient) while AGE was secondary to E. coli (1 patient). The treatment was mainly symptomatic and included fluid restriction, transfusion of red cell concentrates, diuretics, peritoneal dialysis and hemodialysis. The evolution was marked by the onset of chronic renal failure (1 patient) after 6 months of follow-up and by recovery (1 case). Three patients died. HUS is the most common cause of organic acute renal failure in newborns. Diagnosis is essentially biological, treatment is mostly symptomatic.

Hypothyroïdie congénitale à Dakar: à propos de 28 cas

Child hypothyroidism has been little studied in Senegal. The aim of this study was to evaluate the epidemiological, diagnostic and evolutionary aspects of congenital hypothyroidism. We conducted a descriptive-analytical retrospective study of all children treated for congenital hypothyroidism at the Albert-Royer National Childrens Hospital Center over the period from 2001 to 2014 (14 years). We collected and analyzed socio-demographic, clinical and evolutionary data from patient medical records. A total of 28 patients were included in the study, an average of 2 cases per year. The average age of discovery of hypothyroidism was 54.25 ± 43 months with a female predominance (Sex-ratio 0.47). Only 2 cases of hypothyroidism were diagnosed in the neonatal period. Consanguinity was present in 68% of patients. Clinical signs were dominated by the delay in psychomotor acquisitions (96%), hypothermia (46%), cranio-facial dysmorphia (43%) and goiter (39%). Growth retardation was constant beyond 6 months. The etiologies were dominated by hormonosynthesis disorders (84.21%). During the study period, mean SD of patients had decreased from -3.5 SD to -2.25 SD for a median treatment duration of 28 months. Mental retardation was present in 73% of cases. Growth retardation and mental retardation were more severe as the diagnosis was late. Our results confirm the inadequacy of early management of patients. It is urgent to implement a routine neonatal screening system in order to improve the mental prognosis of this condition.
