ABSTRACT

Introduction: le test Xpert MTB/RIF présente un double avantage d'une part le diagnostic rapide des cas mêmes difficiles par la technique standard de l'examen direct à la microscopie et d'autre part par la détection de la résistance à la rifampicine. Notre objectif était de déterminer l'apport du test Xpert dans le diagnostic de la tuberculose toutes formes confondues. Matériels et méthode : étude transversale, descriptive à collecte rétrospective menée dans le service de Pneumophtisiologie de CHRU de Saint-Louis. Tous les cas suspects de tuberculose qui avaient bénéficié d'un test Xpert de 2018 à 2020avec un dossier médical accessible et exploitable ont été inclus. Les paramètres étudiés étaient les données sociodémographiques, cliniques et biologiques. Résultats : Nous avions colligés 524dossiers de malades avec un sex-ratio de 1,3. L'âge moyen des patients était de 37 ans+/-15 ans. Il y'avait 285 prélèvements positifs au GeneXpert dont 224 d'origine pulmonaire et 61d'origine extra pulmonaire. Le nombre d'échantillons résistants à la rifampicine était de cinq, tous d'origine respiratoire. Conclusion: le test Xpert est une nouvelle technique moléculaire recommandée par l'OMS dans le diagnostic de la tuberculose pulmonaire. Toutefois il doit être évaluer dans le diagnostic de la tuberculose extra pulmonaire


Introduction: The Xpert MTB / RIF assay has a dual advantage on the one hand, the rapid diagnosis of even difficult cases by the standard technique of direct microscopic examination and on the other hand by the detection of resistance to rifampicin. Our objective was to determine the contribution of the Xpert test in the diagnosis of tuberculosis of all forms. Materials and method: retrospective, descriptive and analytical study carried out in the Pneumophtisiology department of the CHRU of Saint-Louis. All suspected tuberculosis cases who had received an Xpert test from 2018 to 2020 were included. The parameters studied were socio-demographic, clinical and biological data. Results: 524 patient records included in the study with a sex ratio of 1.3. The mean age of the patients was 37 +/-15 years. There were 285 positive GeneXpert samples, of which 224 were of pulmonary origin and 61 of extra-pulmonary origin. The number of rifampicin resistant samples was five, all of respiratory origin. Conclusion: the Xpert test is a new molecular technique recommended by the WHO in the diagnosis of pulmonary tuberculosis

ABSTRACT

INTRODUCTION: Diabetes prevalence has increased over the past years. In Senegal, this prevalence is 4% in the general population. However, the region of Saint-Louis (in the north of the country) has the highest rate with 10.4%. The main prognosis problem is the occurrence foot lesions that can lead to lower-limbs amputation. Diabetic foot is a real public health issue, due to its economic burden and its serious repercussions on patients, leading to poor quality of life. The objective of this case-control study is to identify factors associated with foot lesions in diabetic patients. METHODS AND ANALYSIS: It will be a case-control study from January to December 2021. The patients will be recruited from the departments of general surgery, internal medicine, and emergency. An univariate then multivariate analysis (logistic regression) will allow us to select the variables associated with foot lesions in our study population. The parameters included in the logistic regression will be those with a p < 0.20 in the univariate analysis. Finally, a binary logistic regression analysis (with the calculation of Odds Ratios (OR) with confidence intervals (CI)) according to the backward stepwise method will identify the factors independently associated to foot lesions in diabetic patients. ETHICS AND DISSEMINATION: This research protocol will be submitted to the Ethics Committee of our institution for approval. The knowledge of factors causing diabetic foot will help to communicate with policymakers to raise the awareness in our community. Finally, it will help to prevent lower limb amputations. HIGHLIGHTS: Diabetes is the leading cause of non-traumatic lower-limb amputation in the world.The region of Saint-Louis (Senegal) has the highest prevalence of diabetes.Controlling factors associated with foot lesions in diabetic patients can prevent from amputation.

ABSTRACT

INTRODUCTION: Gallstone disease is a disorder characterised by the formation of stones in the biliary tract. It is the most common biliary condition accounting for more than 98% of all gallbladder and biliary tract disorders. In Africa, previous studies have shown a relative rarity of this condition with a prevalence less than 5%; since it is between 2 and 5 times higher in other continents. A good knowledge of the profile of patient with gallstone disease in a surgical setting could allow to reduce gallstone disease complications and to tailor better the treatment. To our knowledge, there was no previous study about gallstone disease in this region even if there is a high prevalence of metabolic factors of gallstone disease. METHODS: This study objective is to describe the epidemiological, diagnostic and therapeutic profile of patients with gallstone disease at the Department of General Surgery of Saint-Louis Hospital (Senegal). It will be a single-centre retrospective cohort study in a period of 5 years (January 2015 - December 2020). The patients' record of the department of general surgery will be consulted and the patient contacted if there are missing data. Patients with gallstone disease diagnosed with imaging (ultrasonography and/or CT scan) regardless the presentation (asymptomatic, biliary colic, cholecystitis, common bile duct lithiasis, angio-cholitis, pancreatitis) will be included. Adults and paediatric patients will be enrolled. Patient records lacking sufficient data will be excluded. Studied parameters will be epidemiological, clinical, paraclinical and therapeutic aspects. ETHICS AND DISSEMINATION: Anonymity and confidentiality of information collected in patients will be respected. This research protocol will be submitted to the Ethics Committee of our institution for approval. The knowledge of the profile of patients with gallstone disease in a surgical setting could allow to reduce gallstone disease complications and to tailor better the treatment. Finally, it will help to reduce the burden of gallstone disease. HIGHLIGHTS: Gallstone disease is the most common biliary tract conditionTo our knowledge, there was no previous study about gallstone disease in this region even if there is a high prevalence of risk factors of gallstone disease (sickle cell disease, diabetes, obesity, hypercholesterolemia)Good knowledge of the profile of patients with gallstone disease in a surgical setting could allow to reduce gallstone disease complications and to tailor better the treatment.

ABSTRACT

Pulmonary tuberculosis is still a global scourge, especially in developing countries, despite the control measures that have been in place for decades. The aim of this work was to describe the epidemiological, clinical radiological and evolutionary aspects of PMPT at the Saint-Louis Regional Hospital Center. This was a retrospective descriptive study on 191 PMPT files, hospitalized in the medical department from January 1, 2016 to December 31, 2017. PATIENTS AND METHOD: Were included in the study, all cases of pulmonary tuberculosis proved by the presence of bacillus Koch on direct examination of sputum. Were excluded from the study, cases of pulmonary tuberculosis with negative microscopy and cases of pulmonary tuberculosis in patients younger than 14 years. RESULTS: Of 1417 hospitalizations, 191 patients had a PTPM. The average age was 36.5 years with extremes of 14 to 81 years. The sex ratio was 2.2 in favor the male. Fishermen were the most affected with 34% of cases. A family tuberculosis was noted in 61 patients. One hundred and forty-six new PMPT cases were noted. CONCLUSION: Positive microscopy pulmonary tuberculosis remains a public health problem in Senegal. Much work remains to be done in Saint-Louis, which a region with a high burden of tuberculosis.

ABSTRACT

INTRODUCTION: Stomach cancer is a real public health problem in Black Africa. We report its epidemiological, endoscopic, and histological aspects, as observed in our gastrointestinal endoscopy center at Aristide Le Dantec University Hospital in Dakar (Senegal). PATIENTS AND METHODS: This retrospective study covered the 5-year period from January 1, 2006, to December 31, 2010 and included all patients with stomach cancer confirmed by anatomo-pathological examination. We collected data about age, sex, indications for the examination, and description of the gastric lesions and any other associated lesions from the upper GI endoscopy reports. We also recorded information from the histological reports of all lesions. RESULTS: The study included 101 patients. The incidence of gastric cancer was 20 cases/year. Patients' mean age was 58 years [range: 24-83]. The sex ratio was 2.48. The main indications for the upper GI endoscopy were epigastralgia (33.3%), vomiting (26.1%), and tumoral hepatomegalia (10.81%). The examination found mainly ulcerative and protruded lesions (59.40%). Other types of lesions associated with the tumor were esophageal candidiasis (34.6%), peptic esophagitis (25%), and gastroesophageal junction incompetence (25%). The tumor was located in the antrum in 68% of the cases and was an adenocarcinoma in 83.2%. CONCLUSION: A cancer register to determine the characteristics and prevalence of stomach cancer in Senegal would be useful. The link with Helicobacter pylori requires further study.

ABSTRACT

Diabetes represents a challenging global health issue in the 21st century. Data from sub-Saharan African populations are scarce and are usually restricted to urban settings. The objective of this study was to compare prevalence and risk factors of diabetes in rural and urban areas in Senegal. Methods. In a community-based survey between January and May 2012, we included 1027 adults aged ≥18 years living in northern Senegal. Sociodemographic, clinical, and biological data were collected during household visits. Multivariate logistic regression was performed to identify factors associated with diabetes. Results. Mean age of participants was 48.0 ± 16.9 years and 65.7% were female. Participants from urban area represented 55.7%. The age-standardized prevalence of diabetes was 7.6% (6.0% in men versus 9.0% in women). Prevalence of diabetes was higher in urban areas (8.1%) compared to rural areas (4.6%). Disease awareness rate was 43%. After multivariate analysis, age (OR = 1.63, p = 0.001), familial history of diabetes (OR = 1.42, p = 0.001), and abdominal obesity (OR = 1.17, p = 0.05) were associated with diabetes. Conclusion. Diabetes is frequent in urban and rural areas in Senegal. Awareness rate is very low among populations. Age, family history of diabetes, and abdominal obesity are the main risk factors identified.

ABSTRACT

INTRODUCTION: High blood pressure (hypertension) is a growing public health problem, and its impact on the overall health of patients in Africa is not well known. The objective of this study was to determine its prevalence and its influence on self-rated health among people living in rural areas of Senegal. POPULATION AND METHODS: This cross-sectional study was conducted over a two-week period in the rural communities of Labgar and Lougré Thiolly, located in the central northern region of Senegal, in an agricultural area. Randomly recruited volunteers were questioned during direct individual interviews about socio-demographic (age, sex, marital status, education, occupation) and lifestyle data (smoking or alcohol, physical activity). Clinical data (medical history, weight, height, blood pressure, course of treatment) were also collected. Self-rated health (SRH) was assessed by asking if they felt their health was bad or good. RESULTS: We included 627 patients with a mean age of 40.93 ± 17.2 years (range: 15-100 years), 59.9% of them women. Illiteracy and overweight were more common among women than among men, and smoking and alcohol consumption more frequent in men. The overall prevalence of hypertension was 23.4% and did not differ significantly between men (24.9%) and women (22.4%)(P = 0.50). Self-rated health was similar in men and women (with respectively 66.9% and 72.9% reporting good health, P = 0.10). On univariate analysis, the factors associated with perceived health status were age (OR = 1.34, P = 0.04), smoking (OR = 2.16, P = 0.03), educational level (OR = 1.21, P = 0.04), and the presence of hypertension (OR = 0.63, P = 0.05). The multivariate regression analysis showed that among women, advanced age (≥50 years) and hypertension (≥140/90 mmHg) were associated with poorer perceived health, whereas for men, only smoking was significantly correlated with poor health status (OR = 0.41, P = 0.01). CONCLUSION: This study shows that hypertension is common in this rural area of Senegal and is significantly associated with a lower self-rated health in women but not men. In the absence of longitudinal studies in these populations and given the predictive value of SRH, this correlation suggests higher morbidity and mortality in women with hypertension.

ABSTRACT

OBJECTIVE: Severe acute colitis (SAC) is one of the major complications of inflammatory bowel disease (IBD), especially ulcerative colitis, and it is life-threatening. Although IBD is considered rare in sub-Saharan Africa, we report 2 fatal cases of SAC in Senegalese patients with ulcerative colitis in Dakar. CASES: One patient was a 73-year-old man and the other a 35-year-old woman. In both cases, the diagnosis was preceded by a chronic dysenteric syndrome (febrile in the woman). Despite antibiotic treatment for potential infectious colitis, both patients' condition worsened. Second-line treatment of parenteral corticosteroids did not prevent the occurrence of intestinal perforation for the man, who developed multiorgan failure. The woman developed toxic megacolon during antibiotic treatment, and it was fatal despite bolus corticosteroids: cardiovascular collapse with shock (case 2) occurred before emergency surgery could begin. Conclusion: in subtropical zones where infectious colitis predominates, it is important to consider the diagnosis of SAC in patients with ulcerative colitis and to begin appropriate treatment despite the fear of infection and the difficulty of accessibility to endoscopic exploration.

ABSTRACT

OBJECTIVES: To report the prevalence of spontaneous bacterial peritonitis (SBP) and its clinical and laboratory features in patients with cirrhosis followed at the Aristide Le Dantec Hospital in Dakar (Senegal). PATIENTS AND METHODS: From May through December, 2010, we prospectively included patients with cirrhosis and a first episode of ascites on clinical examination. Diagnostic abdominal paracentesis was performed in all cases to determine the macroscopic appearance of the fluid, protein concentration, and cell count, and to culture the ascitic fluid in a blood culture bottle. SBP was diagnosed when the fluid contained more than 250 polymorphonuclear leukocytes per cubic millimeter of fluid. The data were analyzed with Epi-Info software, version 3.5.2. Comparisons used Fisher's exact and Chi-square tests, with significance set at p < 0.05. RESULTS: The study included 55 patients with cirrhosis, with a mean age of 45 years and a male/female sex ratio of 1.89 (36 men). The prevalence of SBP was 27.3%. Factors significantly associated with SBP were female gender, malnutrition, turbid appearance of the ascites, and neutrophilia. In samples from patients with SBP, the mean protein concentration was 20.7 g/L, the white cell count was 1797/mm(3), and the neutrophil count 1,102/mm(3). Ascitic fluid culture was positive in 20% of the SBP cases (n=3). CONCLUSION: In Dakar, cirrhosis is found especially in young adults, and the prevalence of SBP in our population was 27.3%. Improved technical equipment would improve the hospital's ability to determine the causes of cirrhosis and identify the various germs responsible for SBP.

ABSTRACT

Encapsulating peritoneal sclerosis (EPS) is a rare but potentially lethal complication of peritoneal dialysis (PD). Peritoneal tuberculosis is considered an etiologic factor. We report a case of EPS in a 40-year-old man who was switched to hemodialysis because of peritoneal tuberculosis after 2 years of PD. Because of the persistence of gastrointestinal symptoms and cachexia, laparoscopic exploration was performed, which revealed an important thickening of the peritoneal membrane sheathing the intestinal loops. Accordingly, a diagnosis of EPS was made. Anti-tuberculosis treatment associated with a low dose of corticosteroids stabilized the disease.

ABSTRACT

Examining the meanings of the experiences of advanced practice nurses (APNs) who chose to work with older adults and why they continue to work with this population was the focus of this hermeneutic qualitative research study. Twelve geriatric APNs currently practicing in two South Central states were interviewed using an open-ended interview guide. Using Gadamerian hermeneutics, the researchers identified Gerontology Found Me as the significant expression that reflected the fundamental meaning of the experience as a whole. Four themes emerged that further described the meanings of the participants' personal, educational, and professional experiences: Becoming a Gerontology Nurse, Being a Gerontology Nurse, Belonging to Gerontology, and Bringing Others to Gerontology. This study concluded that APNs' personal and professional experiences were more influential than educational experiences to become geriatric nurses, and having these personal and professional experiences of being in relationship with older individuals further contributed to their choice of gerontology.

ABSTRACT

INTRODUCTION: The association hyperthyroidism-exophtalmia is pathognomonic of the Graves disease. Classically, the treatment is based on a pluridisciplinary step-by-step approach with a precise chronology. In some African places, these optimal conditions are not present. When confronted to such particular situations, it can be proposed to treat surgically at the same time the endocrine disease and the ophthalmologic complications. OBSERVATION: The authors report the case of a 42-year-old women suffering of a great thyreotoxic goiter with severe bilateral exophtalmia, treated by thyroidectomy and orbital decompression in the same session with a good result after 18 months. DISCUSSION: This non-conventional approach can be useful in particular situations when the medical environment is not optimal. It permits the radical treatment of their disease and improves the prognosis of patients with poor capacities for survey.

ABSTRACT

After a preliminary study in the gastrointestinal endoscopy center of the Aristide-Le-Dantec Teaching Hospital in Dakar, Senegal, demonstrated the feasibility and effectiveness of endoscopic ligation of esophageal varices, this procedure entered regular use for management of patients admitted for upper digestive tract bleeding due to these varices. This study sought to assess its effectiveness. Patients and method. This study, conducted from July 2005 through January 2010, included all patients with upper digestive tract bleeding due to rupture of esophageal varices. Results. In all, 140 patients with a mean age of 36 years [range: 16-75] were admitted for this diagnosis and included in the study: 93 men and 47 women (sex-ratio = 1.98). The presence of at least one clinical sign of portal hypertension was noted in 72% of cases. Esophageal varices were graded as stage III in 75.7% of cases. The underlying cause of portal hypertension was cirrhosis in 94.3%, presumptively due to hepatitis B virus among 37.1%. The varices were successfully eradicated in 64 patients (45.7%). The mean number of sessions required was 2 [range: 2-4] in patients with stage II and 3.4 [range, 3-8] in patients with stage III varices, and the mean number of bands applied per session was 5.1 [range: 2-6] and 5.6 [range: 2-10], respectively. The interval between sessions was 4 weeks [range: 3 -12]. Bleeding recurred in 8 patients (5.7%) before eradication was achieved; 4 (2.8%) of them died. Conclusion. Esophageal variceal ligation is an effective therapeutic and prophylactic procedure for management of esophageal varices in Senegal.

ABSTRACT

The molecular epidemiology of Helicobacter pylori in Africa is poorly documented. From January 2007 to December 2008, we investigated 187 patients with gastric symptoms in one of the main tertiary hospitals in Dakar, Senegal. One hundred and seventeen patients were culture-positive for H. pylori. Polymorphisms in vacA and cagA status were investigated by PCR; the 3'-region of cagA was sequenced, and EPIYA motifs were identified. Bacterial heterogeneity within individuals was extensively assessed by using an approach based on vacA and cagA heterogeneity. Fourteen per cent of H. pylori-positive patients displayed evidence of mixed infection, which may affect disease outcome. Patients with multiple vacA alleles were excluded from subsequent analyses. Among the final study population of 105 patients, 29 had gastritis only, 61 had ulcerated lesions, and 15 had suspicion of neoplasia based on endoscopic findings. All cases of suspected neoplasia were histologically confirmed as gastric cancer (GC). The cagA gene was present in 73.3% of isolates. CagA proteins contained zero (3.7%), one (93.9%) or two (2.4%) EPIYA-C segments, and all were western CagA. Most of the isolates possessed presumed high-vacuolization isotypes (s1i1m1 (57.1%) or s1i1m2 (21.9%)). Despite the small number of cases, GC was associated with cagA (p 0.03), two EPIYA-C segments in the C-terminal region of CagA (p 0.03), and the s1 vacA allele (p 0.002). Multiple EPIYA-C segments were less frequent than reported in other countries, possibly contributing to the low incidence of GC in Senegal.

ABSTRACT

OBJECTIVE: In response to the lack of cancer register and paucity of publications on esophageal cancer in Senegal, this retrospective descriptive single-center study was undertaken to determine epidemiological, clinical, endoscopic and histological features of the disease at a digestive endoscopy center in Dakar. PATIENTS AND METHOD: Reports describing upper digestive tract endoscopy procedures performed at the Aristide Le Dantec Teaching Hospital in Dakar between January 2006 and December 2009 were reviewed. Cases involving histologically confirmed esophageal cancer were compiled and patient data including age, sex, and indication for endoscopy as well as endoscopic and histological findings were analyzed. RESULTS: A total of 78 reports were collected including 76 patients with suitable data for analysis. Esophageal cancer accounted for 0.97% of upper digestive tract endoscopy procedures performed. Mean patient age was 49 years and the sex-ratio was 1.9. The main indication for endoscopy was dysphagia (92.1%). The most frequent endoscopic finding involved budding lesions with (42%) or without (29%) ulceration. The most common location was the middle third of the esophagus (50%). The most frequent histological type was squamous cell carcinoma (92.1%). CONCLUSION: Esophageal cancer observed at the endoscopy center of the Aristide Le Dantec Teaching Hospital in Dakar mainly affects young male adults. Lesions are generally located in the middle third of the esophagus and corresponded to squamous cell cancer. There is a need to establish a cancer register and to conduct multicentric studies to gain insight into risk factors for esophageal cancer in Senegal.

ABSTRACT

PURPOSE: Rheumatoid arthritis is the most common chronic inflammatory joint disease in adults. In Senegal, where biotherapy is unavailable, treatment of RA relies on a combination of glucocorticoids and disease-modifying antirheumatic drugs (DMARD). Since DMARD, particularly methotrexate, induce hepatotoxicity pretreatment assays of serum transaminase and albumin levels, as well as serological tests for the hepatitis B and C viruses is recommended. Hepatitis B virus (HBV) infection is endemic in Africa, particularly in Senegal. The purpose of this study was to assess the seroprevalence of the HBV surface antigen (HBsAg) for HBV in 258 patients with RA in Senegal as a basis for defining the least hepatotoxic DMARD for these patients and ensuring the most suitable monitoring. METHOD: This retrospective study was based on a review of the medical records of patients examined between January 2005 and December 2009 at the rheumatology outpatient clinic of the Aristide Le Dantec Teaching Hospital in Dakar, Senegal. All patients met the American College of Rheumatology criteria for RA. RESULTS: A total of 258 patients were tested for HBsAg. Tests were positive in 6 for a seroprevalence of 2.3%. All 6 positive patients were women with a mean age of 48.7 years (range, 16-79 years). Transaminase levels were normal in 5 patients. In the remaining patient, ASAT level elevation were twice normal and ALAT was normal. No patients had clinical evidence of liver disease. CONCLUSION: HBsAg seroprevalence in our population of patients with RA was lower than in the general population of Senegal: 2.3% versus 15%-18%. No evidence indicated that HBVinfection produced specific features in patients with RA. Based on these findings, widespread use of methotrexate in optimal dosages appears safe in patients with RA in Senegal. Treatment should be accompanied by careful attention to HBV prevention.

ABSTRACT

INTRODUCTION: The bacteriological characteristics of Helicobacter pylori (HP) vary in function of time and place. The aim of this study was to update histological and bacteriological feature of HP infection in patients presenting gastroduodenal lesions in Dakar, Senegal. PATIENTS AND METHOD: This prospective study included patients with gastroduodenal lesions managed over a 6-month period in a digestive endoscopy center in Dakar. In all cases gastric biopsy was performed to obtain specimens for histological diagnosis according Sydney modified classification and HP culture with antibiogram. RESULTS: A total of 158 patients were included. Mean patient age was 48.7 years and the sex-ratio was 1.2. Endoscopic lesions were ulcer in 88 cases, gastritis in 54 cases and tumors in 16. Histological examination demonstrated chronic gastritis in 100% of cases, inflammatory activity in 79.1%, metaplasia in 78.5%, gastric atrophy in 41.1%, adenocarcinoma in 7.6%, dysplasia in 5.7%, and MALT lymphoma in 2.5% with presence of HP in 72.8% of cases. Cultures were positive for HP in 65.8% of cases. Antibiograms indicated that HP was sensitive to amoxicilline in 100% of cases, clarithromycine in 96.6%, ciprofloxacine in 84.1%, and métronidazole in 29.5%. CONCLUSION: Chronic gastritis is a constant feature of gastroduodenal lesions in Dakar. Histology combined with culture showed HP infection in 78.5% of cases. The antibiotic sensitivity of HP in Dakar has changed over the past decade.

ABSTRACT

INTRODUCTION: Rectal bleeding is a common reason for seeking medical attention and can lead to diagnosis of serious disease. The purpose of this report is to describe lesions discovered by coloscopy in patients assessed for rectal bleeding in Dakar, Senegal. PATIENTS AND METHODS: This retrospective study was carried out from January 2006 to December 2008 at the Aristide Le Dantec University Medical Center in Dakar. Coloscopy reports involving patients presenting with rectal bleeding were compiled. Age, quality of preparation, use of sedation, and lesions observed were analyzed. RESULTS: A total of 143 patients underwent coloscopy for rectal bleeding. Mean patient age was 51.3 years (range, 2 to 85 years) and the sex ratio was 1.7 (90 men). Preparation was considered as good in 55.5% of cases. Sedatives were used in 57% of cases. Coloscopy findings were normal in 9.8% of cases. The most common lesions were hemorrhoids (53.14%), rectocolitis (17.5%), cancer (11.9%), polyps (11.2%), and diverticulosis (11.2%). Multiple lesions were found in 20 patients (14%). CONCLUSION: Coloscopy for assessment of rectal bleeding in Dakar revealed a range of lesions with hemorrhoids and rectocolitis accounting for most.
