Comparison of in-hospital mortality in children and adolescents with sickle cell disease in a resource-limited setting before and during the COVID-19 pandemic.

BACKGROUND: COVID-19 in children and adolescents with sickle cell disease (SCD) has variable presentations (from mild to severe disease), and the main symptoms are vaso-occlusive crises (VOC) and acute chest syndrome (ACS). We hypothesized that the desertion of hospitals due to the pandemic would lead to late arrival at the emergency room and an increased mortality. In this study, we sought to measure and compare the mortality of children with sickle cell disease before and during the COVID-19 pandemic. MATERIAL AND METHODS: We conducted a retrospective cohort study at the sickle cell disease management center of Laquintinie Hospital in Douala (Cameroon). The study period was divided into two, i.e., from March 2019 to February 2020 (Pre-COVID-19) and from March 2020 to February 2021 (COVID-19). All administrative and ethical considerations were fully respected. Data were analyzed using SPSS 20.0. RESULTS: Overall, 823 patients were admitted during the study period. Males represented 52.4% of the overall population, giving a sex ratio of 1.1:1. We admitted 479 patients during the pre-COVID-19 period versus 344 patients during the COVID-19 period, which is a 28.2% drop in admissions during the COVID-19 period. The mortality rate was 3.5% during the pre-COVID-19 period and 3.2% during the COVID-19 period (p>0.05). The most common causes of death were ACS (39.3%, n = 11), severe anemia (25.0%, n = 7), and VOC (17.9%, n = 5). ACS (adjusted odds ratio [aOR]=3.628, 95% confidence interval [CI], [1.645-7.005], p<0.001) was significantly associated with mortality. CONCLUSION: During the COVID-19 pandemic, although the consultation frequency decreased, the mortality rate of sickle cell disease patients remained unchanged.

Describing the growth and nutritional status of sickle cell disease children and adolescents with reference to WHO growth standards in Cameroon.

BACKGROUND: Sickle cell disease (SCD) is a chronic disease with many complications among which is growth retardation. Here, we described the growth and nutritional status patterns of children with SCD and adolescents living in Douala, Cameroon. METHODS: This cross-sectional study took place at the sickle cell treatment center of Douala Laquintinie Hospital from November 2015 to April 2016. The sociodemographic and anthropometric information of each SCD patient was determined, and then used for computing z-score indexes (weight for age, weight for height, body mass index for height, and height for age). The different indexes were used to determine the prevalence of malnutrition forms (stunting, wasting, underweight, and overweight/obesity) and compared to WHO standards by gender and age. RESULTS: A total of 208 children and adolescents participated in the study. The mean age was 8 years (±5) and the median age was 7 years. Males accounted for 53.4% of cases, giving a sex ratio of 1:1.1. The proportions of wasting, stunting, underweight, and overweight/obesity in the overall population were 7.1% (n = 15), 9.1% (n = 19), 3.6% (n = 5) and 3.3% (n = 7) respectively. In children under 5, wasting, stunting, underweight, and overweight/obesity were noted in 1.4% (n = 1), 9.5% (n = 7), 1.4% (n = 1), and 5.4% (n = 4) respectively. In patients aged 5 years and above, a proportion of 10.5% (n = 14) was wasted, 9.0% (n = 12) were stunted, 5.9% (n = 4) were underweight and 2.2% (n = 7) were overweight/obese. The growth curve of children under five in our study was superimposable to the WHO standard growth curve. In children older than 5 years, the left shift for stunting was more pronounced for boys compared to girls. CONCLUSION: Nine percent of children and adolescents with SCD are stunted. The growth deficit appeared to be higher in patients aged 5 years and above, more particularly in boys than girls. Overweight/obesity was uncommon in our series. More robust research designs and statistical analyses are needed to confirm or refute these findings.

A case report of ruptured ectopic pregnancy plus massive hemoperitoneum on a heterotrophic pregnancy in a resource-poor setting, Mbengwi, Cameroon.

Heterotopic pregnancy is a rare obstetrics phenomenon and carries significant maternal morbidity and mortality due to the risk of rupture of the ectopic pregnancy. Physicians tend to feel comfortable and relieved when an intrauterine gestation sac is seen. This results in an inadequate inspection of the adnexae and remaining structures during emergency bedside ultrasound despite a strong initial clinical suspicion of ectopic pregnancy. We present a case report of ruptured ectopic pregnancy and massive hemoperitoneum in a patient with heterotopic pregnancy. The diagnosis was done on bedside ultrasonography in a clinically unstable 32-year-old patient with a history of infertility. She presented with acute abdominal pain, body weakness, and amenorrhea. She underwent emergency laparotomy and salpingectomy. In our context where ultrasound is not readily available, practitioners carrying out salpingectomy for ruptured ectopic pregnancies should bear in mind the plausibleness of heterotopic pregnancy to properly handle the uterus.

Malaria in patients with sickle cell anaemia: burden, risk factors and outcome at the Laquintinie hospital, Cameroon.

BACKGROUND: It is believed that the current prevalence of malaria in endemic areas reflects selection for the carrier form of sickle cell trait through a survival advantage. Malaria has been incriminated as a great cause of mortality in people with sickle cell disease (SCD). However, people with SCD, a high-risk group, do not benefit from free or subsisized malaria prevention and treatment in Cameroon unlike other vulnerable groups which may be due to insufficient evidence to guide policy makers. This study aimed at describing clinical and socio-demographic characteristics of patients with malaria, determining the prevalence of malaria in hospitalized children and in those with SCD and without, compare frequency of presentation of malaria related complications (using clinical and laboratory elements that define severe malaria) between children admitted for malaria with SCD and those without and finally, determing the risk factors for death in children admitted for malaria. METHODS: This was a retrospective analysis of admission records of children age 1 to 18 years with a confirmed malaria diagnosis admitted at the Laquintinie Hospital during January 2015 through December 2018. Clinical features, laboratory characteristics and outcome of malarial infections, stratified by SCD status were studied. Patients with HIV infection, malnutrition, renal failure and discharged against medical advice were excluded from the study. Data were analysed using Epi-info 7 software and analysis done. Chi square test, Odds ratios, CI and student's t test were used to determine association between variables. Statistical significance was set at p-value ≤0.05. RESULTS: The prevalence of malaria was lower among children with SCD than it was among children without SCD (23.5% vs 44.9%). Similarly, among those with a positive microscopy, the mean parasite density was significantly lower among children with SCD than it was among children without SCD (22,875.6 vs 57,053.6 parasites/ µl with t-value - 3.2, p-value 0.002). The mean hemoglobin concentration was lower in SCD as compared to non SCD (5.7 g/l vs 7.4 g/l, t-value - 12.5, p-value < 0.001). Overall mortality in SCD was 3.4% and malaria was reponsible for 20.4% of these deaths as compared to the 35.4% in non SCD patients. Convulsion and impaired consciousness were significantly lower in SCD group (OR:0.1, CI: 0.1-0.3, p value < 0.01 and OR:0.1, CI:0.1-0.2, p-value < 0.001 respectively). Death was significantly higher in SCD patients with malaria as compared to SCD patients admitted for other pathologies (3.2% vs 1.5%., OR:2.2, CI:1-5, p-value 0.050). CONCLUSION: The SCD population has a lower mortality related to malaria compared to the non-SCD population. Meanwhile, within the SCD population, those admitted with malaria are twice more likely to die than those admitted for other pathologies. Jaundice, hepatomegaly and splenomegaly were common in SCD with malaria, however no risk factors for malaria severity or malaria related death was identified.

[Administration of analgesics at home for the treatment of vaso-occlusive crises before admission to hospital]. / Traitement antalgique des crises vaso-occlusives à domicile avant l'arrivée en consultation.

INTRODUCTION: vaso-occlusive crises (VOCs) are the primary reason for admission and hospitalization in children with sickle cell disease and most often they require home care before arriving to consultation. The purpose of this study was to describe home-based therapy for children with sickle cell disease admitted with VOCs. METHODS: we conducted a descriptive and analytical cross-sectional study, in the pediatric emergencies at the Mother and Child Centre of the Chantal Biya Foundation (CBF) over a 4-month period from February to May 2018. Consecutive sampling was used. All patients with sickle cell disease presenting with VOCs were included in the study. RESULTS: one hundred and fifty-two patients were enrolled. The most represented age group was 5- 10 years. Eighty-two patients (54%) presented more than 24 hours after the onset of the crises and 70 (46%) in the first 24 hours; 80% (n=122) of our sample had received analgesic treatment at home. Escalation of therapy was found in 31.2% of cases. The use of prescription medications (75.4%, n=92) was dominant as the 1st recourse. The dosage for analgesics was not correct in 67% of cases (overdose in 70% of cases). The correct dosage of home-based analgesics was administered in only 33% of patients. CONCLUSION: this study shows that home-based management of VOCs is inadequate. Measures must be taken to ensure that all patients with sickle cell disease can effectively manage minor to moderate VOCs at home.

Predictors of mortality of pediatric burn injury in the Douala General Hospital, Cameroon.

INTRODUCTION: Burn injuries are a major cause of hospitalization and are associated with significant morbidity and mortality, particularly in children aged four years or below. In Cameroon, the mortality rate of pediatric severe burns was estimated at 41.2%. There is need to determine the predictors of such mortality in order to guide appropriate management. METHODS: This study is aimed at assessing the predictors of mortality of pediatric patients who sustained a burn injury over a period of 11 years (between 1st of January 2006 and 31st of December 2016) in Douala General Hospital (DGH). The data for this study was entered in an electronic questionnaire and analyzed using Epi info version 7. All variables thought to be associated with mortality were entered in a multiple binary logistic regression model. The magnitude or risk was measured by odds ratio, and the 95% confidence interval was estimated. RESULTS: A total of 125 cases of pediatric burns were recorded over the study period. A total of 69 (55.65%) were males, giving a male to female ratio of 1.25:1. The median age was 4 years. Most pediatric burns resulted from accidents. Most patient 78 (69%) came before 8 hours following injury. Scalding was the predominant mechanism of injury in 56 (45.5%) of patients. Most patients had partial thickness burn and most burns involved 1-9.9% body surface areas (BSA). The mean length of hospital stay in this study was 7 days, more than half of the patients had no complications during admission. Among those that developed complications, 19 (35%) developed sepsis. CONCLUSION: Mortality rate of pediatric burns obtained in this study was 29%, mostly due to cardiac arrest. Flame burns (p=0.03) and BSA >25% (p=0.001) were statistically significant predictors of mortality.

Management of face presentation, face and lip edema in a primary healthcare facility case report, Mbengwi, Cameroon.

Face presentation is a rare obstetric event and most practitioners will go through their carriers without ever meeting one. Face presentation can be delivered vaginally only if the foetus is in the mentum anterior position. More than half of the cases of face presentation are delivered by caesarean section. Newborn infants with face presentation usually have severe facial oedema, facial bruising or ecchymosis. These syndromic facial features usually resolved within 24-48 hours.
