Introduction: Unconjugated bilirubin jaundice is a common symptom in neonatal period. In some babies, excessive serum bilirubin concentrations can place them at risk of acute bilirubin encephalopathy (BE) when the unconjugated pigment crosses the blood-brain barrier. Our study aimed to describe epidemiology, diagnosis and prognosis of BE at the Neonatology Department of Albert Royer Children's Hospital of Dakar. Materials and Methods: It was a retrospective, descriptive study of cases of BE from January 1, 2015 to June 30, 2019. Obstetric and perinatal data as well as postnatal jaundice data (onset time, associated signs, signs of encephalopathy, treatment and evolution) were collected and analyzed by SPSS software version 2.0. Results: We collected 30 cases of BE (1.14% des admissions) with average age of 6.7 days andsex-ratio of 1.3. Majority were term babies (29 cases; 96.7%) and 7 (23.3%) had intrauterine growth retardation. Almost all newborns (27 cases; 90%) were exclusively breastfed. At admission, all children exhibited blunt jaundice and signs of encephalopathy dominated by the abolition of archaic reflexes (76.7%), low suction (22 cases; 73.3%), central apnea (12 cases, 40%). The mean serum bilirubinemia was 322 mg/litre. Neonatal infection (10 cases; 33.3%) and fetal-maternal incompatibility (16 cases; 53.3%) were the main causes. All children received intensive phototherapy and exsanguino transfusion was performed for 7 newborns (23.3%). Nine children died (30% mortality rate). Conclusion: Only better organisation of perinatal care with enhanced postnatal follow-up can reduce the incidence of EB.
Introduction: Bilirubin encephalopathy is a debilitating complication of severe neonatal unconjugated bilirubin jaundice. The aim of this study was to determine the frequency of occurrence of this complication and to describe the diagnostic and prognostic aspects in Senegal. Materials and Methods: This was a multicenter, descriptive and analytical study conducted in 32 neonatal units of various levels, with retrospective (January to December 2020) and prospective (January to August 2021) collection. All neonates hospitalized for acute bilirubin encephalopathy were included. The diagnostic criteria were the presence of jaundice associated with neurological signs (muscle tone disorders, abnormal movements, convulsions, etc.), with no other obvious etiology found. The data were entered and analyzed using SPSS version 23 software. The significance threshold was retained for a p-value < 0.05. Results: We registered 151 patients. The mean age was 6 days and the sex ratio was 2.5 (clear male predominance). The majority of newborns were from Dakar (51%). Twenty-two (22%) were premature and 32% had low birth weight. Half of the newborns (50%) came from home and 87% were exclusively breastfed. The average time to consult was 3 days. Neurological signs were dominated by decreased primitive reflexes (74%), abnormal movements (59%) and lethargy (50%). Dehydration (30%) and anemia (26%) were often associated. The mean bilirubin level was 416 umol/l. Neonatal infections (19%) and Rhesus (16.7%) and ABO (8.7) incompatibility were the main causes.
Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases characterized by enzymatic deficiencies in the biosynthesis of adrenal steroids. The most common 21-hydroxylase deficiency is characterized by a cortisol deficiency and an excess of androgens, with or without aldosterone deficiency. In our countries, in the absence of neonatal screening, the diagnosis is most often late leading to life-threatening complications. The aim of this study was to describe the diagnostic features of CAH at the Albert Royer National Children's Hospital (ARNCH) in Dakar. Patients and method: We conducted a retrospective, descriptive study carried out at the pediatric endocrinology department of ARNCH from 2015 to 2019. All children aged under 15 with a form of CAH were included. Socio-demographic data, family history, clinical and biochemical data at presentation were collected. Patients were noted as presenting with Disorder of Sexual Development (DSD) with dehydration, DSD without dehydration, dehydration without DSD, precocious puberty. The Prader's scale was used to determine the degree of external virilization. These data were entered and analyzed with Epi Info version 7.2. Results: A total of 32 patients were included, representing 74.41% of the causes of disorder of sexual development (DSD) and 84.21% of the causes of adrenal insufficiency. These were 27 girls (84.37%) and 5 boys (15.63%). The mean age was 19 ± 34.6 months. DSD was the main finding (87.5%). It was associated with dehydration in 22 cases (68.75%).
Objective: Primary immunodeficiencies are rarely related in sub-Saharan Africa. The aim of this study was to identify their different clinical patterns, to describe their biological phenotypes and to analyse treatment. A cross-sectional observational study over a period of 4 years and 2 months in 5 Senegalese paediatric departments was conducted. Children were recruited according to the recommendations of African society for immunodeficiencies (ASID) or the 10 warning signs for PID's diagnosis. Biological explorations were performed in these patients. Results: 30 cases of PID were recorded. The sex ratio was 1:1; with a median age at diagnosis of 24 months. The most common clinical patterns were respiratory infections (18 patients) including tuberculosis pneumonia in almost one-third of cases (22%), followed by digestive and then cutaneous manifestations. This signs occurs in a specific context; as inbreeding (36, 7% of cases), death in sibling (30% of cases), or previous hospitalizations (66, 7%). Biological exploration made it possible to obtain immunological confirmation in 10 children, including one genetically confirmed. The most common category of PID was syndromic PID. Treatment was based mainly on antibiotic prophylaxis. PID are a reality in Senegal, but are certainly underestimated. Continue recruitment will enable advocacy for access to certain treatment.
