This review is part one of three, which will present an update on diagnostic procedures for gastrointestinal (GI) submucosal tumors (SMTs). Part two identifies the classification and part three the therapeutic methods regarding GI SMTs. Submucosal tumors are typically asymptomatic and therefore encountered incidentally. Advances in diagnostic tools for gastrointestinal submucosal tumors have emerged over the past decade. The aim of this paper is to provide the readers with guidelines for the use of diagnostic procedures, when a submucosal tumor is suspected. Literature searches were performed to find information on diagnostics for gastrointestinal submucosal tumors. Based on the searches, the optimal diagnostic procedures and specific features of the submucosal tumors could be outlined. Standard endoscppy, capsule endoscopy and push-and-pull enteroscopy (PPE) together with barium contrast X-ray do not alone provide sufficient information, when examining submucosal tumors. Endoscopic ultrasound (EUS), computed tomography (CT), magnetic resonance imaging (MRI) and fluorodeoxyglucose-labeled positron emission tomography (FDG-PET) are recommended as supplementary tools.

Introduction: Palatal abscess or cellulitis of dental origin is a rare clinical form of circumscribed cellulitis that can sometimes pose a diagnostic problem. It is the consequence of poor or non-treatment of dental caries or trauma. The aim of this study is to describe the clinical and therapeutic aspects of these two cases of palatal cellulitis of post-traumatic dental origin. Observation: The patients consulted for painful palatal swelling secondary to untreated dental trauma of the 21s. The diagnosis of palatal cellulitis was based on the inflammatory and fluctuating nature of the swelling. A probabilistic bi-antibiotic treatment and an incision and drainage associated with treatment of the portal of entry were carried out. Progression was favourable in both cases. Conclusion: Palatal cellulitis is a rare condition and can be prevented by systematic stomatological consultation after dental trauma. Diagnosis is clinical. However, CT scans are sometimes useful. The course is generally favorable with appropriate treatment.

Introduction: Corticosteroid therapy used in rheumatology is effective but can lead to complications. The objective was to describe the complications of corticosteroid therapy in rheumatological practice at Ignace Deen University Hospital (Conakry). Methods: Cross-sectional study from July 1, 2022 to March 31, 2023. All patients who had been diagnosed with a rheumatological disease and who had received corticosteroid therapy were included. Results: Of the 1489 patients suffering from rheumatological diseases, 238 (15.9%) had received corticosteroid therapy. The average age of the patients was 48.5 ± 17.16 years with a female predominance (70.5%). The main indications for corticosteroid therapy were lower back pain due to probable disco-radicular impingement (35.8%) followed by rheumatoid arthritis (21.9%). The predominant method of administration was infiltration (56.9%). The average dosage was 24.2 ± 13.5 mg prednisone equivalent (range: 5 mg and 40 mg). Complications were present in 26 patients (10.9%) such as muscle cramps (3.8%), hypocalcemia (3.4%), edema of the lower limbs (3%), stimulation of appetite and weight gain (3%), high blood pressure (2.5%), hyperglycemia (2.5%). The occurrence of complications was associated with the high dose of corticosteroid (p = 0.014) and long-term use (p = 0.000). Conclusion: Corticosteroid therapy used in 15.9% of consultations in the rheumatology department of Ignace Deen University Hospital led to 10.9% of complications. These complications were related to the dose and duration of corticosteroid therapy.

Introduction: COVID-19, an emerging infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), typically presents with mild clinical manifestations in pediatric populations. As in many other regions of the Democratic Republic of the Congo (DRC), the COVID-19 pandemic affected children in Haut-Uélé, a province bordering South Sudan and Uganda. This study aimed to describe the epidemiological profile of COVID-19 in pediatric population in this area. Materials and Methods: This descriptive cross-sectional study was conducted over a 6-month period from August 1, 2021 to February 7, 2022. It included all patients aged 0 to 19 years with confirmed COVID-19 using RT-PCR and managed at the COVID-19 Treatment Centers (CTCO) in ISIRO and WATSA. Data were collected from patient records supplemented by the dataset from the service of Health Information System (SNIS) and the Epidemiological Surveillance Commission of the Provincial Health Division (DPS). Epidemiological and clinical profiles were analyzed. All statistical analyses were performed using SPSS software, Version 18. Results: During the 4th wave of the pandemic, 5 out of 13 health zones in Haut-Uélé province were affected, with a total of 569 recorded cases;45 of them were children aged 0 to 19 years (7.9%). Asymptomatic cases accounted for 33.3% (15 cases). The mean age was 9.88 ± 5.49 years, with the most affected age group being 10 - 14 years (44.45%). There was a predominance of males (73.3%), with a male-to-female sex ratio of 2.75. Half of the patients (53.3%) were from Watsa Health Zone. A seasonal peak was observed between December and January. Comorbidities were present in 10% of infected patients, and nearly half of participants were contacts of infected individuals. The primary reasons for admission were fever (66.66%), followed by rhinorrhea (57.77%) and cough (31.11%). All patients responded favorably to treatment. Conclusion: The proportion of pediatric COVID-19 cases at t

Objective: The COVID-19 pandemic has highlighted the need to strengthen diagnosis and genomic surveillance capacities. In 2021, Central African managed five waves of COVID-19 by integrating genomic surveillance into their health monitoring system. This study sought to report surveillance data from the National Laboratory of Clinical Biology and Public Health and describe the circulation of SARS-CoV-2 variants. Materials and Methods: This retrospective, descriptive observational study spans three years, from April 2020 to November 2023. It was conducted on a population of consenting volunteers from across the Central African Republic, who were tested using RT-PCR on nasopharyngeal samples. Data with sufficient information were obtained from the National Laboratory of Clinical Biology and Public Health (LNBCSP) databases. Sequencing was largely carried out at the National Institute of Biomedical Research (INRB) in Kinshasa until May 2023, and subsequently at the LNBCSP. Results and Discussion: Out of 97,864 RT-PCR tests performed, 9,764 were positive, resulting in a prevalence of 9.98%. The average age of the patients was 39.97 years ± 13.76, and the male-to-female sex ratio was 2.12. RT-PCR test positivity was significantly associated with age (p = 0.001), sex (p = 0.013) and clinical manifestations. Ten variants circulated during the five recorded waves, with Omicron (B.1.1.529), Delta (B.1.617.2) variants being predominant. Notably, the B.1.620 and B.640 variants were prominent during the second wave. Conclusion: This retrospective study provides key insights into the COVID-19 pandemic in the CAR. It identifies risk factors and details the circulation of various SARS-CoV-2 variants. Enhancing national genomic surveillance capacities would enable the country to better respond to future pandemic challenges.

Introduction: Measles remains a worrying health problem in sub-Saharan African countries. There have been measles outbreaks in Cameroon with the most recent occurring between October 2022 and September 2023. The Centre region of Cameroon was the most affected in the country and being at the frontline of the fight against this illness, we conducted this study in order to determine the epidemiological and clinical characteristics as well as the outcome of children who contracted the measles and were hospitalized at the Yaoundé Gynaeco-Obstetric and Pediatric Hospital. Methodology: We conducted a cross-sectional descriptive and prospective study for one year from October 2022 to November 2023 corresponding to the duration of the outbreak. We included all children admitted in the pediatric unit for measles and its complications during this period. Results: In total, 60 children were enrolled. Their caregivers were mostly their mothers who had a mean age of 34.71 ± 9.55 years living in significant precarious conditions for the majority. The median age of children was 16 months (09 - 30 months). Twenty six percent of children (16) were less than 9 months. Girls were predominant (55%). Most children were not up to date with their routine EPI vaccination (80%) and most did not receive the measles and Rubella vaccine (76.67%). Clinical manifestations, included fever, conjunctivitis, and cough. Skin rash and catarrh (98.33% and 86.67% respectively) are the case definition signs of measles. The outcome was unfavorable for 4 children. One had a neurological disorder: coma and three presented with pneumonia and severe respiratory distress (6.67%). Conclusion: Measles is still being a reality and claiming lives in our context, emphasis should be made on immunization coverage and if possible, advocacies should be formulated to decrease the age of measles vaccine administration.

We propose a numerical solution to incorporate in the simulation of a system of conservation laws boundary conditions that come from a microscopic modeling in the small mean free path *** typical example we discuss is the derivation of the Euler system from the BGK *** boundary condition relies on the analysis of boundary layers formation that accounts from the fact that the incoming kinetic flux might be far from the thermodynamic equilibrium.
