Clinical presentation and imaging findings in juvenile-onset back pain: a ten-year hospital-based retrospective analysis in Douala (Cameroon).

Introduction: Studies exploring the clinical and imaging characteristics of juvenile-onset back pain (JOBP) are scarce. The purpose of this study was to assess the clinical presentation, imaging findings, and factors associated with JOBP. Methods: A retrospective record-based study was conducted among all pediatric cases presenting to the Rheumatology unit of the Douala General Hospital, Cameroon, from January 2014 to December 2023. The study did not include children whose back pain began after 16 years of age. Results: Of the 216 records of patients under 18 examined, 67 children (31 girls) were diagnosed with JOBP. The median age was 15 [13-16] years. More than two-third of the children included in this study had chronic pain (n = 46; 68.65%). Pain was mild to moderate in intensity in 48 children (71.6%). Radiculopathy was present in 10 children (14.92%). The most common location of back pain was the lumbar region (n = 64; 95.52%). Some children experienced pain in more than one location. The location of the pain was not associated with gender, duration of the pain, radiculopathy, or practice of a competitive sport (p > 0.05). Musculoskeletal abnormalities on imaging were found in 38 children (62.29%). In multivariate analysis, peripheral joint involvement [aOR = 0.253 (0.073-0.878); p = 0.030] and mild pain intensity [aOR = 0.077 (0.014-0.422); p = 0.003], were independently associated with the presence of musculoskeletal abnormalities on imaging. Conclusion: JOBP affects a third of children and adolescents of our clinic population. The common musculoskeletal abnormalities found on spine imaging are disc diseases and scoliosis.

Diagnosis and treatment challenges of autism spectrum disorder at a reference hospital in Douala, Cameroon.

BACKGROUND: Autism spectrum disorder (ASD) is a neurodevelopmental disability associated with deficiency in social interaction, unusual development of social communication, and restricted or repetitive behaviors, interests and activities. This study aimed to describe management of pediatric ASD in Cameroon, a resource-constrained Central Africa country. METHODS: A retrospective study was conducted between December 2021 and May 2022 at the Pediatrics department of a reference hospital in the town of Douala. Data of interest of children with ASD were collected through eligible medical records and telephone discussions with their parents/guardians. RESULTS: Medical records of 145 children with ASD aged 2-15 years were included in the study, giving a hospital ASD prevalence of 3.7%. Time delay between parental concerns and hospital management was specified in 69 (47.58%) children, and among them 38 (55.07%) had a mean delay ± SD was less than five months. Children were mainly males (76%) and aged 4-5 years (37.93%), with mean age ± SD of 44.4 ± 22.2 months old. The main consultation reason was delayed language development (100%). Mean time delay between parental concerns and the first medical consultation was 18 months (range 1-60 month). Attention deficit hyperactivity disorder were found in 68.18% of children aged ≥ 6 years old. Neuropsychology (66.2%) was the most frequently used intervention. Some children were treated using traditional medicine. CONCLUSIONS: Management of pediatric ASD is strongly influenced by socioeconomic and cultural context. It is crucial to implement behavioral change campaigns in community, organize training sessions to medical staff on diagnosis and treatment of ASD, and provide specialized centers with skilled staff and equipped material.

Clinical, echocardiographic, and therapeutic aspects of congenital heart diseases of children at Douala General Hospital: A cross-sectional study in sub-Saharan Africa.

INTRODUCTION: Cardiovascular diseases in pediatric pathologies have emerged in the recent years in sub-Saharan Africa (SSA), with congenital heart diseases (CHDs) being the most frequent. Unfortunately, their diagnosis is usually delayed, thereby increasing childhood morbidity and mortality. OBJECTIVES: Describe the clinical, echocardiographic, and therapeutic aspects of CHDs of children at Douala General Hospital. METHODS: We carried out a cross-sectional descriptive study over a 10-year period, from January 2006 to December 2015. Files and reports of cardiac ultrasounds of patients aged ≤ 15 years were reviewed. RESULTS: We reviewed the medical records of 1616 children, of which 370 (22.9%) had CHD. The age range was 1 day to 15 years, with a mean of 26 months. Heart murmur was the most frequent clinical sign, seen in 72.3% of the cases. CHD with left-to-right shunt was seen in 61.8%, with ventricular septal defect being the most common (29.8% of all cases). The second most common CHDs were those due to obstruction (20.4%), mainly pulmonary stenosis (19.6% of all cases). Cyanogenic CHDs accounted for 17.8% of cases, dominated by tetralogy of Fallot (7.4% of all cases). Indications for surgical treatment was found in 171 (46.2%) patients, but due to financial constraints, only 48 (28.1%) patients were operated. Among those who underwent surgery, 66.7% were operated abroad, and Humanitarian organizations financed the surgical management of 58.3% of those operated. CONCLUSIONS: CHDs are seen in one out of five children seen in the pediatric cardiology unit of our Hospital for suspected heart disease. Most cases are diagnosed late in life as toddlers. The rate of surgical correction remains low due to financial constraints, with most cases operated abroad with the assistance of Humanitarian organizations.
