Introduction: Cardiac catheterisation plays a fundamental role in the management of acute coronary syndrome. These explorations require heavy, complex and costly equipment and a large team of doctors, nurses and technicians with highly specialized training. Aims: To describe epidemiological, clinical and coronary angiography aspects of patients with acute coronary syndrome. Patients and Methods: Descriptive study from September 2019 to December 2023 in the Cardiology Department of the Hôpital Mère-Enfant of Bamako. Inclusion criteria were patients admitted for coronary angiography with the diagnosis of acute coronary syndrome. Results: During the study period, 1253 patients underwent coronary angiography, 596 of whom had acute coronary syndrome as an indication, representing a hospital frequency of 47%. Sex-ratio was 2.10. Mean age of patients was 58.5 ± 11.39 years. ST elevation acute coronary syndrome was the most common indication with 63.92% of cases. High blood pressure was the main cardiovascular risk factor with 58.7% of cases, and radial access approach was used in 98% of cases. Coronary angiography was pathological in 91.70% of cases (n = 548). Patients with lesions of anterior interventricular artery were 73.73% of cases. Tritruncal lesions accounted for 40.63% of cases. Conclusion: ST elevation acute coronary syndrome is the most frequent manifestation of acute coronary syndrome. Anterior interventricular artery is most often the culprit lesion for our patients.

Water contamination by chemical pollutants is increasingly associated with waterborne diseases worldwide. The objective of this study is to assess the chemical health risk associated with drinking water consumption in Dakar, Senegal. The methodology adopted in this study is based on the determination of trace metals (Cd, Pb, Fe, Cu and Mn) in human drinking water by flame atomic absorption spectrometry, the estimation of the exposure of populations of the study area on the basis of the quantity of water consumed daily and the determination of the hazard quotient which allows estimating the health risk. The results indicate unacceptable levels of Pb and Cd in the water according to World Health Organization (WHO) guidelines, while the concentrations of Fe, Cu and Mn are below the regulatory values. The hazard quotient (HQ) is in the majority of samples higher than 1 in children and infants for scenario 1 (based on WHO data), reflecting a high risk for this target. In scenario 2 based on consumption data from the populations studied, the HQ is greater than 1 only in heavy consumers. The drinking water consumed by Dakar population presents health risks related to Pb and Cd, particularly for infants, children and heavy consumers, hence the need to strengthen the water treatment system before home consumption.

Supracondylar fractures of the humerus are the most common traumatic elbow injury in children. Several techniques are described in their support. Blount’s method is one of the widely used orthopedic means. The objective of our study was to evaluate the results of supracondylar fractures of the humerus treated by this method in our department. This was a descriptive, longitudinal study with the prospective collection over a period of 12 months from May 2018 to April 2019. It focused on children aged 0 to 15 years treated in the Orthopedic Traumatology Department of the CHU of Kati for a supracondylar fracture of the humerus in extension. A minimum follow-up period of 6 months was necessary for inclusion. 12 patients were collected. The sociodemographic, anatomopathologic, therapeutic and evolutionary aspects were studied. The results were evaluated according to Flynn’s criteria. The male sex was predominant with a ratio of 2. The average age was 5.5 years. The average admission time was 12.5 hours. Domestic accidents were the main etiology (66.66%) and Type II fracture was the most frequent with 58.33%. The duration of immobilization was 42 days for 11 patients. Complications were 1 case of secondary displacement and 1 case of 12˚ flexion deficit. The average Baumann angle was 72˚. The result was satisfactory for all our patients. Supracondylar fractures of the humerus are common in children, especially boys. The method of Blount when it is well carried out by respecting the indications gives good results.

Advances in Infectious Diseases 2022年第3期12卷 422-432页

作者： Papa Silman Diawara Mamadou Wague Gueye Sokhna M. daffe Mor Ngom Maguette Ndoye Nata Dieng Ibrahima Diallo Bécaye Fall Macoura Gadji Moustapha Diop Pape Samba Ba Yankhoba Diop Federation of Laboratories Principal Hospital of Dakar Dakar Senegal Hematology Department Dakar Principal Hospital Dakar Senegal Hepato-Gastro-Enterology Department Dakar Principal Hospital Dakar Senegal Department of Biological Hematology & Oncology—Hematology (HBOH) National Blood Transfusion Center (CNTS)/FMPOS-UCAD Dakar Senegal Infectious Diseases Department Dakar Principal Hospital Dakar Senegal

Background: Over the past two decades, blood transfusion safety has made significant advances in the fight against infectious diseases. However, hepatitis B is still a problem in blood banks due to its high endemicity in Senegal. In this context, we proposed to first determine the prevalence of HBs antigen (HBsAg) in regular and new blood donors. Second, to determine the influence of the number of blood donations on the prevalence of hepatitis B. Materials and Method: We conducted a retrospective transversal study using data from all blood donations received at the Principal Hospital of Dakar Blood bank from July 2007 to December 31, 2021. Hepatitis B testing was carried out with Automaton E411 (Roche Diagnostics). For all donors, information on age, sex, hepatitis B serology, and the number of donations was collected through the lab’s computer system. Data entry and statistical analysis were performed with Epi-info version 7. Results: HBsAg carriers were identified in 4311 primary donors, corresponding to a prevalence of 12.39% (IC 95% = 12.04 - 12.74). The prevalence of the HBsAg antigen was higher in men (12.9%) than in women (6.85%). Men are twice as likely to be infected with HBV as women (OR = 2.00 (IC 95% = 1.85 - 2.17)). The highest prevalence (12.4%) was found in young adults (23 - 29) years old. After 10 donations, the prevalence of the HBs antigen was stable at around 1%. Individuals with a single blood donation and individuals with 2 to 5 blood donations are 9 and 7 times more likely to carry the HBs antigen than regular donors (more than 10 blood donations), respectively. Conclusion: Our results demonstrate the endemic nature of hepatitis B in Senegal. On the other hand, the non-negligible prevalence of the virus in first-time donors reminds us of the need for continuous improvement in donor selection. These first-time donors, particularly young adults, are important indicators of transmission of the virus to the general population. This study also demo

Background: Chronic hepatitis B virus (HBV) infection is one of the largest public health problems with nearly 350 million chronic carriers and 500,000 deaths each year. These deaths are most often associated with disease progression to cirrhosis or hepatocellular carcinoma, which some studies have shown is associated with long-term viral replication in chronic carriers. Viral load quantification, a key element of disease management, is expensive and difficult to access. Viral load plays a crucial role in patient classification and treatment initiation. Four years after the implementation of viral load platform, the objective of this study was to assess viral load profile in HBs chronic carriers in a sub-Saharan Hospital and to determine the potential impact of this distribution on preventive and therapeutic strategies against hepatitis B infection. Materials and Method: The study was carried out between April 2016 and October 2020 in the laboratory of the PRINCIPAL Hospital in Dakar. All patients referred for HBV DNA viral load testing following a positive AgHBs test were included. Incomplete medical records were excluded from the study. Only the first quantification test performed on each patient is recorded. DNA extraction was performed with COBAS AmpliPrep (Roche Molecular Systems, Inc., Branchburg, NJ, USA). Amplification was performed using COBAS TaqMan48 (Roche Molecular Systems, Inc., Branchburg, NJ, USA). Data were collected from the laboratory’s computer system and entered into Microsoft Excel (2007). Statistical analyzes were performed using Epi-Info 7 software. Results: A total of 3002 patients, 76.1% (2285/3002) men and 33.9% (717/3002) women, were included in the study. Young adults were most represented among the subjects (23.2%) and (20.1%) in the age groups 25 - 30 and 30 - 35. The majority (52.7%) of patients had viral loads between 20 and 2000 IU. Patients with undetectable viral loads and patients with viral loads below 20 IU comprised 14.6% and

Background: Sickle cell disease is one of the most common monogenic diseases in the world, affecting approximately 70 million people, 80% in sub-Saharan Africa and 1 in 10 in Senegal. Sickle cell anemia causes functional asplenia (associated with repeated thrombosis of splenic vessels), resulting in increased susceptibility to infection. However, several studies have reported differences in the spectrum of bacterial infections in malaria-endemic areas. Therefore, we proposed to conduct a study to determine the rate of positive blood cultures and the bacteriological spectrum in sickle cell patients. Materials and Method: This is a descriptive cross-sectional study of blood culture samples from patients who received a request for hemoglobin electrophoresis as part of their treatment at the Principal’s hospital in Dakar. The study took place from January 2008 to December 2021. For each patient, we collect demographic information, including age, gender, and the service from which the analysis request originated. Data were collected in the laboratory’s computer system and entered into Microsoft Excel (2007). Statistical analyzes were performed using Epi-Info 7 software. Results: Our study included 1419 patients. The most common types of hemoglobin profiles were: normal profile (n = 1025), AS profile (n = 283), SS profile (n = 104), SC profile (n = 7). This corresponds to the proportions of 72%, 20%, 0.5% and 7.5% for the profiles Normal, AS, SC and SS. The male proportion was 61.1%, 61.5%, 57.1, respectively %, 55.8% for Normal, SA, SC, and SS profiles. A total of 19,090 individual blood culture bottles were collected from 1419 impatient patients as follows: Normal profile (n = 18,042 bottles), AS profile (n = 677 culture bottles), SS profile (n = 362 bottles). The majority of blood culture orders come from pediatric services, accounting for 70% of the total number of orders. Of 19,090 vials examined in this current study, 19.6% developed a positive blood culture. Overal

Scleroderma (or systemic sclerosis) is a disease characterized by abnormalities in the functioning of small blood vessels and the immune system, ultimately leading to inflammation and excessive fibrosis of the skin and various organs, including the heart. Management must be multidisciplinary, to avoid complications that are often serious. We report the case of a 20-year-old patient with no known cardiovascular history who consults for dyspnea, and retrosternal pain associated with a dry cough. On physical examination, she had tachycardia, swelling of the lower limbs, jugular turgidity, and deafening heart sounds. Cardiac Doppler ultrasound shows dilation of the right cavities, paradoxical septum and significant pulmonary arterial hypertension, pericardial effusion of medium abundance. On oral examination, it presents an ulceration of the lips, dermatological examination finds scattered hypo chromic spots in the body, more accentuated in the face. Before the hypo chromic dermatosis, a dermatological consultation was carried out with an autoimmune assessment that came back positive for systemic scleroderma.

Introduction: High blood pressure is a major public health problem worldwide due to its frequency and cardiovascular complications. Adherence to treatment for chronic diseases is a global problem. The aim was to study therapeutic adherence in hypertensive patients followed in ambulatory. Materials and Methods: This was a cross-sectional, descriptive study with prospective recruitment that took place from July 1 to December 31, 2022 (6 months) in the cardiology department of the university hospital of Kati. The variables studied were sociodemographic data, cardiovascular risk factors, comorbidities, the possession of insurance and compliance (the Girerd questionnaire was used to assess adherence). Results: A total of 1182 patients were consulted, including 887 for hypertension, a frequency of 75%. Fifty-six patients were included in the study. The average age was 58.18 ± 13.25 years with extremes of 30 and 80 years. There was a female predominance (75%) with a sex ratio of 0.3. The majority of patients lived in urban areas (89.3%). Out-of-school patients accounted for 44.6%, more than half of patients or 55.4% had no income, patients with medical coverage accounted for 67.9% of cases. The main risk factors were physical inactivity (25%) followed by smoking 14.3%. More than 71% of patients had a compliance problem and the main reasons were forgetting to take the drug with 73.2%, followed by delayed treatment of 50% and drug discontinuation of 28.6%. Conclusion: Compliance is a real challenge and a major public health issue. This study allowed us to find a real problem of compliance in our hypertensive patients. There was a statistically significant relationship between drug adherence and forgetting to take the drug and drug discontinuation.
