Predictors of prolonged length of hospital stay and in-hospital mortality in patients aged 1-24 months with acute bronchiolitis in Douala, Cameroon

INTRODUCTION

In Cameroon, acute bronchiolitis has been reported as the third commonest lower respiratory infection and is usually associated with low mortality. Nonetheless, respiratory distress associated with non-adherence to management guidelines can prolong hospital stay. This study aimed to explore predictors of prolonged hospital stay (≥ 5 days) and mortality in patients aged < 2years hospitalised for acute bronchiolitis.

METHODOLOGY

We conducted a retrospective cohort study at three paediatric units in the city of Douala, Cameroon. Factors associated with prolonged hospital stay and mortality were determined using multivariable linear regression model. Threshold for significance was set at p ≤ 0.05.

RESULTS

A total of 215 patients with bronchiolitis were included with mean age of 6.94 ± 5.71 months and M/F sex ratio of 1.39/1. Prolonged hospital stay was reported in 46.98% and mortality in 10.70% of patients hospitalised for bronchiolitis. Factors independently associated with prolonged hospital duration were oxygen administration [b = 0.36, OR = 2.35 (95% CI:1.16-4.74), p = 0.017], abnormal respiratory rate [b = 0.38, OR = 2.13 (1.00-4.55), p = 0.050] and patients presenting with cough [b = 0.33, OR = 2.35 (95% CI: 1.22-4.51), p = 0.011], and diarrhoea [b = 0.71, OR = 6.44 (95% CI: 1.6-25.86), p = 0.009] on admission. On the other hand, factors independently associated with mortality were age of the patient [b= -0.07, OR = 0.84 (95% CI: 0.74-0.97), p = 0.014] and oxygen administration [b = 1.08, OR = 9.64 (95% CI:1.16-79.85), p = 0.036] CONCLUSION: Acute bronchiolitis represented 1.24% of admissions and was common in the rainy season, in males and 3-11-month-old patients. Management guidelines were poorly respected. Prolonged length of stay was reported in half of the patients hospitalized and mortality was high, especially in younger patients and in patients receiving oxygen.

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.

Evaluation of CRP as a marker for bacterial infection and malaria in febrile children at the Douala Gyneco-Obstetric and Pediatric Hospital

BACKGROUND

C reactive protein (CRP), a marker for the presence of inflammation, has been extensively studied for distinguishing bacterial from non-bacterial infection in febrile patients, but its role in excluding malaria in the febrile child has not been thoroughly evaluated.

METHOD

This was a cross-sectional study at the Douala Gyneco-Obstetric and Pediatric Hospital which included all patients between the ages of one month and 16 years presenting with fever. Consenting patients received complete clinical examinations, then venous blood samples were collected and tested for CRP values, bacterial infection and malaria.

RESULTS

Samples of 220 children were analyzed. 142/220 had viral infections, 50/220 had malaria and 49/220 had bacterial infections. 7/220 had both malaria and bacterial infection. There was no significant difference between mean CRP values in malaria and bacterial infection (p = 1), but CRP means were significantly higher in malaria/bacterial infection than in viral infection (p<0.0001). Area Under the Receiver Operating Characteristics Curve (AUROC) values were 0.94 for malaria and 0.86 for bacterial infection, with a calculated cut-off of 23.6mg/L for malaria and 36.2mg/L for bacterial infection. At these cut-offs, CRP had a Positive Predictive Value (PPV) of 68.75% and 85.00% for malaria and bacterial infection respectively, with a Negative Predictive Value (NPV) of 94.74% and 89.05% respectively.

CONCLUSION

CRP can effectively exclude malaria and bacterial infection in febrile children in low-resource settings without the need for additional tests.

Epidemiological, clinical, and treatment-related features of children with cerebral palsy in Cameroon: A hospital-based study

BACKGROUND

Pediatric cerebral palsy (CP) remains a poorly studied public health problem in sub-Saharan Africa, especially in Cameroon. This study aimed at determining the epidemiological, clinical, and treatment-related characteristics of CP in Cameroonian children.

METHODS

A cross-sectional study was conducted at the pediatric department of the Douala Gynaeco-Obstetric and Pediatric Hospital (DGOPH). Medical records of children attending the department during the study period were reviewed. Only medical records of children aged from 3 months to 15 years and diagnosed with CP were included. Parents/guardians of children presenting with CP were contacted and invited to come with their children to the DGOPH where they were examined by a pediatric neurologist. A questionnaire designed for the study was used to collect sociodemographic, clinical, paraclinical, and treatment data for each child.

RESULTS

Out of the 4064 medical records reviewed, CP was diagnosed in 198 children (4.86%). These children were predominantly male (53.6%), aged 3-24 months (54.0%). Perinatal disorders were the main CP etiologies, especially neonatal asphyxia (55.1%), jaundice (32.8%), and neonatal infections (25.8%). Most of the children were born at term (81.6%) and by vaginal delivery (62.6%), with a normal birth weight (83.2%). Several comorbidities were found including speech delay (74.2%) and epilepsy (34.4%). The patients with CP presented predominantly with the spastic form of the disease, especially spastic quadriplegia (44.3%). Less than half of the children were managed at hospital, while the majority of parents were following various traditional treatments.

CONCLUSION

Addressing preventable causes of CP and improving awareness in the population will be of great help to reduce CP in Cameroon.

Atrésie rectale membraneuse: présentation tardive à propos d’un cas

L´atrésie rectale et la sténose rectale sont des formes rares de malformations anorectales représentant seulement un à deux pourcent des cas vus. Nous rapportons un cas d´atrésie rectale. Il s´est agi d´un nouveau-né de sexe féminin accouché à terme par voie basse pesant 3600g à la naissance qui était admis à J6 de vie pour absence d´émission de méconium, ballonnement abdominal et fièvre. L´examen avait permis de noter une température à 39^ºC, un abdomen distendu, un anus normalement situé et perméable, laissant prolabée une masse bien rosée, sans signe de nécrose. L´introduction d´un stylet entre la masse et la muqueuse rectale butait à environ 3cm de la marge anale. La radiographie de l´abdomen sans préparation montrait des anses distendues et des niveaux hydro-aériques sans signe de perforation d´organes creux. Devant la suspicion d´une atrésie rectale membraneuse complète, une ponction avec un cathéter 16 gauge à travers la membrane avait ramené le méconium dont l´aspiration d´une quantité abondante de méconium avait permis un affaissement considérable de l´abdomen. Nous avons ensuite réalisé une exérèse chirurgicale de la membrane. Les suites opératoires immédiates ont été simples et le nouveau-né était sorti à J3 post opératoire de l´hôpital. Des dilatations anales ont été faites pour traiter une sténose anale. Avec un recul de 6 mois, le résultat est excellent. L´atrésie rectale présentée sous forme d´absence d´émission de méconium associée à une masse prolabée par l´anus ne semble pas encore décrite. La ponction à travers la membrane rectale atrésique a permis de confirmer le diagnostic. La résection de la membrane donne de bons résultats.

Use of WhatsApp®, for distance teaching during COVID-19 pandemic: Experience and perception from a sub-Saharan African setting

BACKGROUND

In the midst of the COVID-19 pandemic, to palliate to the lockdown and cover academic programs, the faculty of medicine and pharmaceutical sciences (FMPS) of the university of Dschang (UDs) in Cameroon has implemented e-learning using WhatsApp®.

AIM

Describe the opinion of students and lecturers after its implementation of e-learning at the FMPS of UDs.

METHODS

We designed a uniform teaching scheme using WhatsApp® during the university lockdown. Students and members of the teaching staff of the FMPS of UDs were enrolled after receiving clear information on the study implementation. At the end of the online-teaching period of two and a half months, we surveyed our students and teaching staff. Sociodemographic characteristics and opinions about e-learning were collected using a standard questionnaire.

RESULTS

We enrolled 229 students and 40 lecturers of the FMPS. Students reported a decremented quality of internet connection (p < 0.001, p-homogeneity < 0.001) despite an increased expenditure related to internet use. Electronic devices were broadly used before the implementation of mobile learning. The use of course materials was significantly more challenging among students because of the size/format of lecture notes and internet connection/cost (all p < 0.05). Perception of discipline compared to classroom-based lessons was not significantly different among students compared to lecturers (all p > 0.05). While lecturers were mainly more comfortable conveying the contents of their lectures, students tended to be less prone to actively participate. The motivation and satisfaction of the latter group toward e-learning were modest compared to classroom-based lectures while their feedback about the organization was positive.

CONCLUSIONS

E-learning using WhatsApp® could be an effective alternative to conventional classroom-based lessons in the context of COVID-19 pandemic. The use of a blended-learning program including classroom-based sessions could help improve its limitations.

Prevalence and factors associated with low back pain in schoolchildren in Cameroon, sub-Saharan Africa

BACKGROUND

Data on the prevalence and factors associated with low back pain (LBP) in schoolchildren are scarce in Africa, particularly in sub-Saharan Africa.

OBJECTIVES

To assess the prevalence and factors associated with LBP in schoolchildren in Cameroon.

PATIENTS AND METHODS

We performed a cross-sectional study in 10 randomly selected schools (public and private) in Douala, Cameroon. Using a self-administrated questionnaire, sociodemographic, usual physical activity, and clinical data were collected and all the schoolbags were weighted. Informed consent was obtained from the parents. Statistical significance was established at P < .05. Logistic regression was performed to identify factors associated with LBP.

RESULTS

We included 1075 schoolchildren (543 boys, 50.5%). The prevalence of LBP was 12.3% (132 children: 81 girls and 51 boys). The mean age was 11 ± 1 years (range, 8-14 years). Body mass index was normal in 110 schoolchildren (83.4%). Sixteen schoolchildren had already met a physician for LBP. Among the factors evaluated, those associated with LBP were female gender, doing competitive sport, sitting position, and LBP in at least 1 parent. The mean weight of the schoolbags was 4.9 ± 1.9 kg. We had 99 children with LBP and a schoolbag weight ≥10% of their body weight. No association was found between the weight of schoolbag and LBP.

CONCLUSION

LBP is common in Cameroonian schoolchildren, where 12.3% suffer from it. The weight of schoolbags was not associated with LBP. However, female gender, competitive sport, sitting position, and parental history of LBP were significantly associated with its occurrence.

Impact and projections of the COVID-19 epidemic on attendance and routine vaccinations at a pediatric referral hospital in Cameroon

Background

At the beginning of March 2020, Cameroon experienced its first cases of infection with the new coronavirus (SARS-COV-2). Very quickly, there was a drop in the rate of hospital attendance. The purpose of this study was to observe the variations in the uptake of pediatric consultations and vaccinations in a pediatric hospital.

Methods

A descriptive and retrospective cross-sectional study was carried out using consultation and vaccination statistics from a pediatric hospital in the city of Yaoundé, political capital of Cameroon, from January 2016 to May 2020. Data were entered in Microsoft Excel and exported to R software (Version 3.3.3) for statistical analysis. First, time series raw data (before and after COVID-19) were plotted and the trend estimated by locally weighted scatterplot smoothing (LOWESS) methods. Then a classic seasonal decomposition was performed to distinguish between seasonal trends and irregular components using moving averages. The Webel–Ollech overall seasonality test (WO test) was also run to formally check for seasonality. The results of the study are presented as narrative tables and graphs.

Results

Following the partial confinement recommended by the government of Cameroon, the number of pediatric consultations decreased by 52% in April and by 34% in May 2020 compared with rates during the same periods in 2019 (P = 0.00001). For antenatal visits, the rates dropped by 45% and 34%, respectively, in April and May 2020 compared with 2019. The demand for immunization services also declined. As a result, the demand for BCG vaccines, third-dose tracer vaccines (diphtheria, tetanus, pertussis), polio, and MMR in children as well as tetanus vaccines in childbearing women dropped significantly.

Conclusion

The start of the COVID-19 pandemic was accompanied by a significant drop in consultation and vaccination activities. If no action is taken to correct this phenomenon, the ensuing months could be marked by a considerable increase in patients, sometimes suffering from vaccine-preventable diseases. The death rate could increase considerably in the pediatric population.

Decrease in Hospitalizations and Increase in Deaths during the Covid-19 Epidemic in a Pediatric Hospital, Yaounde-Cameroon and Prediction for the Coming Months

The COVID-19 pandemic reached Cameroon in March, 2020. The aim of this study was to unveil the consequences of this pandemic on hospitalizations and on mortality in a pediatric hospital. Methods: A descriptive and retrospective cross-sectional study was carried out using hospitalization and death statistics collected from a pediatric hospital. We compared the data before and after the pandemic and made predictions for the next 12 months. Results: A drastic drop in hospitalizations was noted coinciding with the partial lockdown in Cameroon. Paradoxically, at the same time, the number of deaths per month doubled though the causes remained the same as in the past. Conclusion: The COVID-19 pandemic was marked by drop in hospitalizations and paradoxically, an increase in child mortality. These deaths were probably due not to SARS-Cov-2 infection, but rather due to the usual illnesses whose management was delayed, a probable consequence of the confinement.

Impact of the COVID-19 pandemic on pediatricians' clinical activity in Cameroon

BACKGROUND

The outbreak of COVID-19 has imposed many challenges on health systems. The purpose of this study was to describe the impact of the COVID-19 pandemic on the clinical activity of pediatricians.

METHODS

We conducted a cross-sectional and descriptive online survey among pediatricians practicing in Cameroon. Data were collected through an anonymous pre-tested Google Form®.

RESULTS

Among the 118 pediatricians eligible for the survey, 101 responded (85.6%), of whom 61.2% were women. The pediatric outpatient consultations dropped significantly from 60.4% of pediatricians seeing more than 30 patients per week before the pandemic to 9.9% during the pandemic (P<0.000). According to the occupancy rate of hospitalisation beds, 45.5% of pediatricians reported having 76-100% of pediatric hospitalisation beds occupied per week before the pandemic but no pediatrician reported a similar rate during the pandemic (P<0.000). There was a significant increase in the use of telehealth, ranging from no pediatrician using telehealth "very frequently" before the pandemic to 23.8% using it during the pandemic (P<0.000). Most of the pediatricians had at their disposal surgical masks (96%), care gloves (80.2%), hydroalcoholic gel (99.0%), and soap and water (86.1%). For the management of children, 90.1% and 71.3% of pediatricians experienced difficulties accessing COVID-19 PCR and chloroquine, respectively, and 74.3% declared difficulties for proper isolation of patients. More than half (65.3%) of the pediatricians interviewed were "very afraid" or "extremely afraid" of being infected with SARS-Cov-2, respectively 45.5% and 19.8%. The most frequent reasons included fear of infecting their relatives (85.1%) and of developing a severe form of the disease (43.6%). The reluctance to consult health services expressed by the parents was due to: fear of being infected when leaving their home and especially in the health facility (96%), strict compliance with confinement (30.7%), and financial difficulties of families (13.9%).

CONCLUSION

This work highlights the impact of the coronavirus pandemic on the clinical activity of Cameroonian pediatricians. Since the beginning of the pandemic, there has been a significant drop in the use of health facilities, which probably has a negative impact on children's overall level of health. Although the preventive measures explain this drop in attendance at health facilities, the parents' fear of being infected when leaving the house was the predominant reason likely to explain this drop in attendance at health facilities. This could constitute an axis for developing messages to parents to encourage a gradual return to child health services.

Conclusion

[Tetanus in older children in a pediatric hospital in Yaounde, Cameroon]

Le tétanos est évitable par la vaccination, mais peut survenir en cas d'une immunisation incomplète. Nous avons mené une étude sur les dossiers médicaux des enfants admis pour tétanos entre 2008-2009 au Centre Mère et Enfant de la Fondation Chantal BIYA à Yaoundé. Le but était d'analyser les circonstances de survenue et les manifestations cliniques du tétanos chez le grand enfant, afin de proposer des stratégies de prévention adaptées au contexte camerounais. Le statut vaccinal était inconnu chez un patient, les autres (80%) n'avaient pas reçu de rappel vaccinal. Les portes d'entrée étaient les plaies aux membres, l'une était secondaire à une injection médicamenteuse. Tous ont présenté le tétanos généralisé. Le décès était survenu chez un patient. Le tétanos n'est pas rare chez le grand enfant au Cameroun. Il se dégage ainsi la problématique des rappels vaccinaux.
