Bacteriological Profile of Acute Respiratory Infections in Children: About a Prospective Study at the Albert Royer Hospital in Dakar

Introduction: Acute Respiratory Infections (ARI) is a global public health priority. It is the leading cause of childhood morbidity and mortality, especially in developing countries. The main objective of this work was to look mainly at the bacteriological aspects of ARI in children in Senegalese hospitals. Methodology: We have been conducted a prospective descriptive mono-centric study over a period of one year (from July 1, 2017 to June 30, 2018) at the Albert Royer National child hospital in Dakar. A multiplex PCR (protein chain reaction) has been performed on nasopharyngeal swabs taken from all patients. This technique (viral RNA transcribed into DNA, then the DNA of the different pathogens is simultaneously amplified in the same tube by PCR Fast-tract®, multiplex). Results: During the study period, 109 patients were included. The hospital prevalence of acute respiratory infections was 3.7%. The mean age was 23.7 months with extremes between 1 month and 144 months. Peaks of consultations were found in the months of August, March and April with 22%, 15.6% and 12.8% respectively. Fever, respiratory distress and pulmonary condensation syndrome were the main signs found in our patients. Bacteriology was positive in 82.6% of samples and the most frequently found bacteria were Streptococcus pneumoniae in 38.5%, Haemophilus influenza b in 32.1% and Moraxella catarrhalis in 25.7%. Pneumonia was the main diagnosis, found in 61 cases, a prevalence of 59.9%. The average length of hospitalization was 10 days. Lethality was 1.8% or 2 cases. Conclusion: Acute Respiratory Infections in children still remains a public health problem in developing countries;children under 5 years of age are the most affected hence the need to strengthen ARI control programs. The identification of germs is indispensable in treatment and epidemiological surveillance in our regions.

Neonatal Bilirubin Encephalopathy: Study of 30 Cases at Albert Royer National Children Hospital of Dakar

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. 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.

Congenital Adrenal Hyperplasia: Diagnostic Features in a Limited Resource Country, Senegal

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%). 21-hydroxylase deficiency represented 93.75% of the cases with salt wasting in 73.33% of the cases.?Conclusion:?The diagnosis of CAH was delayed leading to life-threatening adrenal crises. In the absence of neonatal screening for CAH in Senegal, there is a need to train healthcare workers to recognize neonates with DSD early and refer them timeously for specialist care.
