Sequelae of thoracic tuberculosis: manifestations and patients'quality of life.

For many patients, a history of tuberculosis is synonymous with disabling sequelae, impaired quality of life, and high morbidity and mortality. This retrospective study reviewed the files of patients hospitalized for sequelae of thoracic tuberculosis during 2017, to assess its various manifestations and their impact on quality of life. Of the 176 patients included, 75 % were aged from 35 to 65 years. They were predominantly male, with a sex ratio of 3.76. The socioeconomic level was mostly low (70 %). Only one episode of tuberculosis sufficed to cause sequelae in 89.8 % of cases. Smoking was often noted (52.3 %). Functional signs were dominated by coughs (90.3 %) and dyspnea (72.7 %). Pulmonary sequelae with fibrous scarring were observed in 52.2 % of the patients. Bacterial and/or viral superinfection was the leading cause of hospitalization (50 %). The death rate during hospitalization was 19 %. An improvement followed by discharge was observed for 81 %, 14.2 % of them with chronic respiratory insufficiency. In all, 13.28 % of the discharged patients died within the 6 months that followed. The sequelae of thoracic tuberculosis should be considered as long-term chronic conditions and deserve the same treatment.

[Epidemiology of primary lung cancer among non-smokers in Senegal]. / Épidémiologie des cancers bronchopulmonaires primitifs des non-fumeurs au Sénégal.

INTRODUCTION: According to global data for 2002, one quarter of new cases of primary bronchopulmonary cancer were non-smokers. We undertook this study with the aim of describing the epidemiological characteristics of non-smokers with primary bronchopulmonary cancer in the Dakar region of Senegal. METHODS: A multicenter descriptive study that included all non-smokers who presented with primary bronchopulmonary cancer between January 1st 2014 and December 31st 2015. The data were captured on an Excel file and then transferred to Epi InfoTM 7 software for analysis. RESULTS: The rate of diagnosis for primary bronchopulmonary cancers was 72.1 %. The prevalence of non-smokers was 33.3 %. The sex ratio was 1.27. The average age was 54.6 years. More than a third of the sample were housewives. Carpenters and craftsmen exposed to metals predominated. Exposure to cooking oils was reported in one case. Three patients presented sequelae of pulmonary tuberculosis. Adenocarcinoma was the most common histological type and predominated in young subjects. CONCLUSION: The proportion of primary bronchopulmonary cancers diagnosed among non-smokers is increasing in Dakar. An analytical study of suspected risk factors would be helpful for prevention.

Profil épidémiologique, clinique et radiologique de la tuberculose pulmonaire A microscopie positive (TPM+) au centre hospitalier régional universitaire de Saint-Louis (CHRU SL)

Introduction : la tuberculose pulmonaire demeure encore un fléau mondial en progression surtout dans les pays en voie de développement, malgré les actions de lutte mises en place depuis des décennies. Le but de ce travail était de décrire les aspects épidémiologiques, cliniques radiologiques et évolutifs de la TPM (+) au centre hospitalier régional de Saint-Louis. Il s'agissait d'étude descriptive rétrospective portant sur 191 dossiers deTPM+,hospitalisés au service de médecine du 1er Janvier 2016 au 31 Décembre 2017. Étaient inclus dans l'étude, tous les cas de TPM+ prouvée par la présence de BAAR à l'examen direct des crachats. Étaient exclus de l'étude les patients de moins de 14 ans, les cas de TPM(-) Résultats : Sur 1417 hospitalisations, 191 patients avaient une TPM+. L'âge moyen était de 36,5 ans avec des extrêmes de 14 à 81 ans. Sex-ratio de 2,2. Les pêcheurs étaient les plus touchés avec 34 % des cas. Un contage tuberculeux familial était noté chez 61 malades. Cent quarante six nouveaux cas de TPM(+) ont été notés. Conclusion : la TPM(+) demeure un problème de Santé Publique au Sénégal. Beaucoup d'efforts restent à faire dans la région de Saint-Louis à forte charge de tuberculose

[Clinical and radiological characteristics of pulmonary tuberculosis in tobacco smokers]. / Particularités cliniques et radiologiques de la tuberculose pulmonaire chez le tabagique.

INTRODUCTION: Tobacco smoke alters lung defense mechanisms against infections and so increases the risk of mycobacterium tuberculosis infection. OBJECTIVE: To determine the particular clinical features of tuberculosis in smokers and identify risk factors. METHODS AND PATIENTS: We conducted a prospective, cross-sectional study over a period of nine months in Dakar, Senegal. The Chi-square test and multiple logistic regression were used to identify differences between smokers and non-smokers and to identify factors associated with clinical outcomes. RESULTS: We included 165 patients with active pulmonary tuberculosis (59 smokers versus 106 never-smokers). The average age of smokers was 43.8±12.7 versus 32.1±13.1 years (P<0.0001). Smokers were overwhelmingly male (98.3% versus 1.8%, P<0.0001). The average delay to consultation was longer among smokers (90 days [30-120] versus 60 days [30-90] ; P<0.0001). In multivariate analysis, alcohol abuse, increasing age, male sex, and an unknown retroviral status were independent risk factors for pulmonary tuberculosis. Haemoptysis was observed more frequently in smokers (49.1% versus 31.1%, P=0.017). With regards to chest X-ray features, smokers presented with more advanced, bilateral and cavitating lung lesions. CONCLUSION: Diagnostic delay and haemoptysis are important characteristics of the pulmonary tuberculosis in tobacco smokers.

[DRESS syndrome secondary to pyrazinamide: An uncommon complication of tuberculosis treatment]. / DRESS syndrome au pyrazinamide : complication rare et grave du traitement antituberculeux.

INTRODUCTION: The Drug Reaction with Eosinophilia and Systemic Symptom (DRESS) is a severe drug-induced reaction. CASE REPORT: We report the case of a 35-year-old man treated by RHEZ for a first episode of a smear positive pulmonary tuberculosis and who developed a DRESS syndrome due to pyrazinamide after twenty days of treatment, associated with a viral reactivation to Human Herpes Virus 6 (HHV6). He had a skin eruption, liver involvement and hypereosinophilia. He fully recovered after drug withdrawal, associated with local and general corticosteroids. He died two weeks after discharge. CONCLUSIONS: Discovery of DRESS syndrome during tuberculosis treatment is an uncommon complication and requires a searching for the responsible drug. That should be difficult because tuberculosis drugs are often given as fixed-dose combination. Physicians have to bear in mind the potential role of pyrazinamide.

Hepatic cytolysis and bicytopenia after 15 days of four-drug tuberculosis treatment in Senegal.

We report the case of a 31-year-old immunocompetent woman residing in Senegal, with localized microscopy-proved pulmonary tuberculosis, complicated by macrophage activation syndrome and associated with viral hepatitis B, identified due to hepatic cytolysis and a bicytopenia.

[Contribution of the Xpert MTB/RIF to the etiological diagnosis of tuberculous pleurisy]. / Apport de l'Xpert MTB/RIF dans le diagnostic étiologique des pleurésies tuberculeuses.

INTRODUCTION: Performance of the Xpert MTB/RIF for the detection of Mycobacterium tuberculosis in pleural liquid is poorly described. The aim of this study was to determine its usefulness for the etiological diagnosis of a tuberculous pleurisy. PATIENTS AND METHOD: We performed a descriptive cross-sectional study, with analytical design, including all the patients having a unilateral serofibrinous pleurisy, exudative, lymphocytic, and sterile. The diagnosis of pleural tuberculosis was considered based on epidemiological, clinical, paraclinical and therapeutic arguments. The Xpert MTB/RIF of the pleural fluid was carried out among all patients. RESULTS: Pleural tuberculosis was confirmed in 301 patients. The median age was 32years. Our study has included 217 men (72.1%) with a final sex ratio of 2.6. The cost of the pleural biopsy coupled with histology made it practicable in only 90 patients (29.9%) with a yield of 80%. The Xpert MTB/RIF of the pleural liquid was positive in only 10 patients (3.3% of the cases). CONCLUSION: Gene amplification by Xpert MTB/RIF of the pleural liquid is much less effective in establishing the diagnosis of tuberculous pleurisy than pleural biopsy, which remains the gold standard.

[Contribution of fiberoptic bronchoscopy in the diagnosis of pulmonary dragging]. / Apport de la fibroscopie bronchique dans le diagnostic des pneumopathies traînantes.

INTRODUCTION: Bronchoscopy is recommended into the exploration of chronic lung diseases. This one is expensive and invasive. We conducted this study in order to assess the benefit of the bronchoscopy in the etiologic diagnosis of chronic lung diseases. PATIENTS AND METHODS: This study was retrospective, descriptive and analytical, using medical records of outpatients and in patients who has done the bronchoscopy in Pneumology Clinic, Fann hospital, Dakar from January 2010 to December 2014. RESULTS: We have reported 159 cases. The sex ratio was 2.2. Middle age was 44 years. Fever was found in 32.7%. Alveolar syndrome was found in 64.8%. The white blood cells (WBC) were normal in 80.7%. Bronchoscopy was contributive in 74.1%. Specimen analysis isolated banals germs in 69.2%, mainly bacteria in 51.6%. Parasitology of the fluid of broncho-alveolar lavage was positive in 28.6%. CONCLUSION: Bronchoscopy stills a use full exploration while diagnosing chronic lung diseases. It should be systematic in chronic lung diseases with or not fever, this, when sputum microscopy a sputum PCR are negative.

[Prevalence of tobacco smoking in primary and secondary schools in the Department of Dakar, Senegal]. / Prévalence du tabagisme dans l'enseignement moyen et secondaire dans le Département de Dakar, Sénégal.

INTRODUCTION: Tobacco smoke is a global health problem, and the largest avoidable cause of death in the world. The objective of our study was to determine the prevalence of tobacco smoking in schools in Dakar area (Senegal). MATERIEL AND METHODS: This descriptive and analytical cross-sectional study was performed from September 2011 to June 2012 in 27 schools of the Dakar area. RESULTS: We questioned 1654 students over a 9-month school period. The mean age was 15±2.5years (range 11-22). The sample included 848 boys (51.3 %), therefore a sex ratio of 1.05. There were 68 smokers (4.1 %) and 60 ex-smokers (3.6 %). The mean age of the smokers was 16.9±2.2years (range 11-22) with a male preponderance of 70.6 % (n=48). Smoking in family members was the initiating factor most frequently reported by smokers (25 %). The average age of ex-smokers was 16.4±2years. Fear of parents' reactions was the most frequently invoked reason for stopping smoking (41.7 %). CONCLUSION: This study confirms the reality of smoking among school children in Senegal and highlights the urgency of the installation of a prevention policy near the young people.

[Smoking among health workers at four large hospitals in Dakar (Senegal)]. / Le tabagisme chez le personnel médical et paramédical dans quatre grands hôpitaux de Dakar.

INTRODUCTION: The addiction to tobacco remains a significant problem in the context of medical practice in African in general and in Senegal in particular. It is an important cause of morbidity and mortality. The main purposes of this study were to establish the smoking habits of hospital staff as a step towards elaborating a strategy for an anti-smoking campaign within the hospital environment. PATIENTS AND METHOD: The study was a cross-sectional, prospective, descriptive going study conducted between 1st March 2007 and May 15th, 2008. We recovered 662 out of 750 questionnaires collected representing a 75% participation rate. RESULTS: Eighty-five respondents reported that they were smokers (12.8%). The sex-ratio was 7.5 times more common in men. The paramedical staff were more likely to smoke than doctors (14% versus 12.2%). The average age of the smokers was of 37.4 years. Women had begun to smoke at an earlier age (17.4 years against 20.5 years). According to the Fagerström test, 87% were averagely or strongly dependent on nicotine. It was mainly the pleasure (41.2%) and the influence of their circle of acquaintances (36.5%) that prompted the staff to smoke. Smoking cessation was most commonly achieved through the use of willpower alone (44.4%). CONCLUSION: The mortality and morbidity arising from the addiction to smoking is entirely avoidable in contrast to other pandemics. Consequently, engagement in the fight against smoking must constitute a major priority for health workers who must set an example for their patients.

[Tuberculosis in elderly persons]. / Tuberculose du sujet âgé

OBJECTIVES: The purpose of this study was to compare the epidemiology, clinical features and clinical course of primary presentations with pulmonary tuberculosis occurring in older and younger patients. PATIENTS AND METHODS: We undertook a prospective, comparative study in the Pneumology clinic of the National University Hospital of Fann in Dakar, from April 1, 2005 to March 31, 2006, collecting data on all patients presenting with a first episode of bacterially confirmed pulmonary tuberculosis. RESULTS: We studied 187 first presentations with confirmed pulmonary tuberculosis including 12.8% (n=24) elderly (>55 years) subjects (20 men and four women) and 87.2% (n=163) younger subjects (105 men and 58 women). In the older subjects, patients were more commonly men (sex-ratio: 5), without formal education, and working in the primary or informal sector. Comorbidities were more frequent in the older group, including smoking (P=0.002), alcohol consumption (P=0.01), diabetes (37.5%) (P<0.005) and obesity with BMI superior than 20 in 25%. Pulmonary shadowing was common (41.7% of the cases), P=0.008 and generally bilateral P=0.0001 with cavitation, but this observation was not statistically significant. COMPLICATIONS: Complications were more frequent in the older patient (20.8%), as was mortality (29.3%, P=0.000) and rate of clinical improvement in response to treatment was less satisfactory (50%) there.

[Smoking among students at the School of Health and Social Development and the Health Service Institute in Senegal]. / Le tabagisme chez les élèves de l'Ecole de Développement Sanitaire et Social et de l'Institut Santé Service.

We have undertaken a transverse study of smoking among students at the National School of Health and Social Development (ENDSS) and the Health Service Institute (ISS) in Senegal. 683 out of 1142 students were questioned. 609 (89%) replied, of whom 313 (52%) were at the ENDSS and 293 (48%) at the ISS. Senior technical students were most strongly represented at 37.8%, followed by student nurses (27.4%) and midwifery students (23.3%). There were more women (n=378) than men with a sex ratio of 0.61. The average age of the population was 27.5 +/- 6.8 years (range 15 to 58). The average age was 26.2 +/- 5.6 years in the women and 29.6 +/- 8 in the men. The group aged 25-34 was significantly the most affected in both men and women (p=0.0000). The population comprised 502 non-smokers (82.4%), 62 ex-smokers (10.2%) and 45 smokers (7.4%).We found variable alcohol consumption in 119 subjects (19.2%) and 5 students admitted using cannabis. The 62 ex-smokers made up 10.2% of the population. The average age was 31.4 years. 25 ex-smokers (40.3%) drank alcohol, with a sex ratio of 1.95. The reasons for stopping smoking were illness and guilt in 27.4% of cases respectively, economic in 24.2%, medical statements on the effects of smoking on health in 17.7% and personal wishes in only 11.3%. The smokers, numbering 45 (7.4%), had an average age of 27.6 +/- 6.6 years with a sex ratio of 2 (p=0.00000). The age of starting smoking was 20.7 +/- 4.2 years for the women and 19.9 +/- 2.9 years for the men. The latter had smoked for an average of 9.2 years. Cigarettes were used by the great majority of smokers. It was associated with alcohol consumption in 35.6% and cannabis in 11.1% of cases. In the men the motives for starting smoking were stress (60%), pleasure (55.2%) and social influence (53.3%). By contrast, among the women, the two main reasons were stress and fashion in 60% (p=0.04). Our students smoked mostly in public places and in their homes. 34 smokers (75.6%) wished to stop (p=0.02) but only 27 of them expressed the need for medical or psychological support to do this. Dependence, quantified by the Fagerström Score, was medium (score 5-6) in 60% (n=27) and strong (score 7-10) in 31.1% (n=14).The estimated monthly cost of smoking increased with the degree of dependence. It was, on average, 12,143 F CFA (18.5euro) in cases of high dependence, representing 37% of the minimum wage in Senegal which is 33000F CFA (50euro). The students understood well the diseases caused by smoking (whether they were smokers, ex-smokers or non-smokers). These comprise mainly pulmonary diseases (96.2%) and cardio-vascular diseases (78.3%) All the recommended methods of the fight against smoking presented in the media, the publicity, national anti-smoking campaigns, personal contact and consultation, received more than 60% of favourable opinions among the total population studied.

[Tuberculosis and diabetes]. / Tuberculose et diabète.

INTRODUCTION: We performed a retrospective case control study for the period between 1st January 1999 and 31st August 2004, comparing the radiological appearances of tuberculosis in 100 diabetics to those in patients matched for age and sex, with pulmonary TB alone presenting to The Chest clinic of the National Hospital of Fann. METHODS AND RESULTS: Diabetes was present in 4.7% of the 2116 patients hospitalized for pulmonary tuberculosis during the period of study and occurred more commonly in men (60%) with an average age of 51 years (73%). 82% had type II, non-insulin dependent diabetes. The various types of radiological lesions classically described in tuberculosis were found in nearly identical proportions in the two groups of patients, with parenchymal shadowing the most frequent appearance in both diabetics (N=86) and controls (N=88). Cavitation occurred significantly less frequently in diabetics (72%) than controls (88%) (p=0.04). Where radiological abnormalities were bilateral, they were worse on the left in the diabetics (27% versus 15% in controls). There was a trend for basal lesions to occur more frequently in diabetics (15%) than controls (3%) (p=0.06). CONCLUSION: Mortality was higher in diabetics (18%) than controls (6%), with death generally occurring within the first 24 hours of hospitalization.
