RESUMO
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.

BACKGROUND: Endomyocardial fibrosis is a restrictive cardiomyopathy that causes heart failure. It is characterized by the fibrotic thickening of the endocardium, sometimes involving the myocardium as well. The lesion generally lies at the apices or inflow tracts of one or both ventricles, associated with more or less severe alteration of the valves. It is a disease of the intertropical regions but is not well known in Cameroon. In this study we describe the first series seen in a pediatric hospital in Cameroon. PATIENTS AND METHODS: A retrospective study was conducted in a pediatric hospital in Yaoundé involving children who had been diagnosed with endomyocardial fibrosis after echocardiographic investigation. We collected the clinical and paraclinical data from consultation records and medical files. RESULTS: Between January 2006 to December 2013, we registered 1430 patients with a cardiac anomaly in our center. Endomyocardial fibrosis was found in 46 patients. Neither sex predominated. Ages at the time of diagnosis varied between 2 and 17 years. Most of the patients were between 5 and 15 years old (80.4 %), with a median of 10 years (interquartile range, 7-13 years). The main complaints were breathlessness, cough, abdominal distension, abdominal, and loss of appetite. Apart from the hyperpigmentation of the lips observed in all our patients, dyspnea was the most frequent physical sign and the diagnosis was made at a time when signs of heart failure were preponderant. Growth retardation was found in all the children examined. All patients were underweight with a median weight for age found below the 25th percentile of the norms according to the National Health Statistics. Lower limb edema was absent even in the presence of voluminous ascites. All subjects had hyperpigmented lips. Despite the cyanotic appearance of the lips, pulse oximetry always gave a normal oxygen saturation level and no cyanosis was seen elsewhere. None of the patients had nail clubbing. Fibrosis more often affected the right ventricle (45/46 patients). The apical obliteration by fibrotic material was found in 43 (93.5 %) patients. Moreover, 36 (78.3 %) patients had pericardial effusion: mild to moderate in 32 subjects and abundant in four subjects. Hypereosinophilia was noted in 57.5 % of the patients. Atrial fibrillation was found in six out of 15 patients who had an electrocardiogram done. CONCLUSION: The modes of clinical presentation of endomyocardial fibrosis are not sufficiently well known in our context. Despite its insidious progression, certain signs such as weight loss and hyperpigmented lips could be very helpful for screening and easing orientation of parents and heath personnel, thus enabling early referral for appropriate investigation. The presence of bulky ascites without edema of the lower extremities should be viewed as strongly suggestive.

We report two cases of ectopia cordis in two children aged one day and twenty months respectively. A one day old newborn had complete thoracic ectopia cordis associated with an internal cardiac defect and severe thoracic and abdominal wall malformations. Our centre does not have the facilities to manage complex congenital defects and prior to being transferred to a cardiac centre, the neonate died on the second day of admission. A 20-month old baby had partial ectopia of the heart and a defect in the abdominal wall. He had no major congenital cardiac defect and has remained clinically stable with no life threatening symptoms.
RESUMO
Hypothalamic hamartoma is an uncommon cause of central precocious puberty and sometimes of gelastic epilepsy and delayed development. The purpose of this report is to describe a case of central precocious puberty in an 18-month-old girl who was referred to our department for further investigation of vaginal bleeding that had appeared during the 8th month of life. The patient's puberty was compatible with Tanner stage 3, her psychomotor development was normal, and epilepsy was not observed. Diagnosis was based on abnormal hormonal workup findings and discovery of a hypothalamic hamartoma on brain magnetic resonance imaging. Neurosurgery was not performed. Administration of long-acting gonadotropin releasing hormone analog to slow puberty led to clinical improvement. Hypothalamic hamartoma must always be suspected in case of central precocious puberty. Although magnetic resonance imaging is the most reliable modality, it is not always available nor affordable in low-income countries. Neurosurgery is not indicated in patients without epileptic seizure. Gonadotropin releasing hormone agonists are usually indicated to slow down puberty and improve the adult height. However, the cost is prohibitive in developing countries.

Leishmaniasis is a disease caused by a protozoan parasite of the genus leishmania with worldwide distribution and is transmitted to man by phlebotomine sand flies. The clinical presentation could range from a single cutaneous ulcer to disseminated leishmaniasis. We report the case of a four-year-old boy admitted to our hospital with ulcers, wasting, progressively distending abdomen, and fatigue evolving for about two months. On admission, he was febrile and pale, with diffuse oozing wet ulcers on the limbs and face, hepatosplenomegaly, and enlarged inguinal lymph nodes. The complete blood count revealed pancytopenia with low reticulocyte count, and serum protein electrophoresis showed hypoalbuminemia and hypergammaglobulinemia. Skin biopsy revealed amastigotes in phagocytic cells. The above findings suggested cutaneous and visceral localization of the leishmania; however, the parents absconded with the boy just when treatment was instituted, believing that the child was bewitched. The outcome is expected to be fatal visceral involvement.

The purpose of this report is to describe an autochtonous case of visceral leishmaniasis with cachexia, fever, splenomegaly, ascitis and severe anemia observed in an eight-year-old boy from a region in eastern Cameroon outside the traditional disease foci. Diagnosis was confirmed based on demonstration of Leishmania amastigotes on bone marrow smear. The patient was treated with meglumine antimoniate but died on the 6th day of treatment.
