Infections sexuellement transmissibles chez les hommes ayant des rapports sexuels avec d'autres hommes suivis à l'Hôpital Institut d'Hygiène Sociale de Dakar

Introduction : Les relations sexuelles entre hommes, constituent un facteur de propagation des infections sexuellement transmissibles (IST) et du VIH/sida dans les pays en développement. L'objectif de notre étude était de déterminer les aspects épidémiologiques, cliniques et thérapeutiques des IST chez les hommes ayant des rapports sexuels avec d'autres hommes (HSH) suivis à l'IHS de Dakar. Malades et méthode : Il s'agissait d'une étude transversale et analytique effectuée sur une période de 4 mois à l'IHS. L'analyse des données était faite grâce au logiciel IBM Statistics SPSS 20. Résultats : Nous avons colligé 31 HSH avec IST symptomatiques, soit une prévalence de 15,65%. L'âge moyen était de 28,25 ans. Quarante-deux pour cent (n = 13) étaient connus séropositifs. Vingt-quatre étaient bisexuels (77,4%). Les types de rapport étaient : réceptifs (38,7% ; n = 12), insertifs (29% ; n = 9) et les deux (32,3% ; n = 10). Ils avaient eu, en moyenne, 5 partenaires occasionnels durant la dernière année. L'utilisation de préservatifs n'était systématique que chez 11 patients (35,5%). Une rémunération des rapports sexuels était notée chez 87% (n =27). Les signes d'IST retrouvés étaient : écoulement (74,2% ; n =23), condylomes (19,4% ; n = 6) et ulcération (16 % ; n = 5). La topographie était : anale (45% ; n = 14) et génitale (54,2% ; n = 17). Le traitement syndromique était efficace chez tous les HSH présentant un écoulement ou une ulcération.Conclusion : Notre étude montre une fréquence élevée des IST symptomatiques, de l'infection à VIH et de la bisexualité chez les HSH suivis à l'IHS. Ces résultats montrent que la lutte contre les IST et le VIH passe nécessairement, en partie, par le renforcement des attitudes préventives chez cette population-clé

[The size of the bile duct by echograph. A study]. / Étude par échographie des dimensions du conduit cholédoque.

UNLABELLED: The purpose of this work was to determine the size of the bile duct by echograph. The frequent injuries of the bile duct in various pathologies in particular infection, made of it a very investigated organ especially by echograph. Its size can be modified by various pathologies. So it is of interest to know about its normal size. PATIENTS AND METHOD: Sixty normal subjects, among which 29 women, were examined by echograph in the university hospital of the Point G. They were voluntary subjects with an empty stomach for 12 hours. Three different sonographers successively performed this examination according to the same protocol with an Aloka SSD 1700 device type and a Kontron Medical/Imagic Maestro. These devices were provided with a convex probe of 3.5-megahertz multifrequency and with a linear probe of 7.5-megahertz. The subjects were in dorsal position. Reference points for the display of the bile duct were the liver, the gallbladder and the pancreas. The limits of the bile duct were marked by the cursor of the echograph. The transverse diameter (in mm) of the bile duct was measured in its origin and in its ending. No subject of the sample was obese enough to hamper the visibility of the gall-bladder and the bile duct and no subject had histories of cholecystectomy. Data analysis was made using the software Ear information version 6. The difference between variables was considered as significant when P<0,05. RESULTS: Forty subjects out of 60 were between 20 and 39 years old. The transverse diameter of the bile duct was measured 38 times (63.3%) in its origin and 50 times (83.3%) in its ending. The failure of visibility of the proximal segment was 37.7% and the failure of visibility of the distal segment of the bile duct was 17.7%. The average transverse diameter of the bile duct in its origin was 2.61.4 mm; extremes were 2 and 5 mm. The average transverse diameter of the bile duct in its ending was 3.10.7 mm; extremes were 2 and 5 mm. The transverse diameter of the bile duct in its origin of the subjects was contained between 3 and 4 mm in 80% of the cases. The transverse diameter of the bile duct in its ending of the subjects was contained between 3 and 4 mm in 40% of the cases. The difference was very significant between the diameter of the bile duct in its origin and in its ending (P<10(-6)). CONCLUSION: The distal segment of the bile duct was seen more accurately than the proximal segment by echograph. The diameter of the bile duct in its ending was significantly superior to that of the bile duct in its origin.

[Factors affecting nosocomial infection in the surgery setting at the Hospital of Point "G"]. / Facteurs influencant l'infection nosocomiale en milieu chirurgical à l'Hôpital du Point "G".

Nosocomial infections are a common and increasing problem globally, and particularly in Africa. The significant economic burden of these infections on the health care system as well as their impact on patient morbidity and mortality is well recognised within the medical communities.The goal of this study was to investigate factors that influence nosocomial infection in all in-patients from the surgery wards (surgery ward A and B, Gynoeco-obstetrics, urology and intensive care) at the national hospital of Point G in Bamako, Mali. We report the number of nosocomial infection during a prospective study between June 2003 and January 2004. Of 1043 in-patients, 102 had had a nosocomial infection with a global prevalence of 9.7% (8.0-11.4). Of 1024 patients with surgery, 101 had had a nosocomial infection, a post-surgery nosocomial infection rate of 9.8% (8.1-11.5). We observed different site of nosocomial infection such as suppuration sup-aponevrotics (41.2%), parietal infection sub-aponevrotics (32.4%), urinary infection (17.6%) and organ suppuration (3.9%). Other nosocomial infection observed were pneumonia (2.9%) and catheterisation (2.0%). The nosocomial infection rate was 10.3% in male while it was 7.3% in female. The difference between male and female was not statistically significative (chi2 = 2.33, p = 0.12). Nosocomial infection was more prevalent in patients after emergency surgery (15.1%) than in scheduled surgery patients (8.5%) (chi2 = 8.15, p = 0.004). The classes III and IV of ALTEMEIER had the higher proportion of nosocomial infection (35.9%) against 4.8% for the classes I and II (chi2 = 144.95, p < 0.001). The patients with ASA score I had a lower nosocomial infection rate than patients from the intensive care unit or patients of Class II + III + IV (chi2 = 13.2, p = 0.001). Patients classified according to the National Nosocomial Infection Surveillance System (NNISS) with a score 0 had a nosocomial infection rate less than patients classified as NNISS score 1, 2 or 3 (chi2 = 82.0, p < 0.001). The study results underline the need for further investigations of the role of microbial agents and antimicrobial resistance in the outcome of patients with nosocomial infection.

[Acquired bacteraemias at the intensive care unit]. / Bactériémies acquises dans un service de réanimation.

Acquired bacteraemias in intensive care unit (ICU) have some serious consequences in terms of morbidity, mortality and costs. The emergence of multiresistant germs in ICUs, and the therapeutic difficulties that ensue, participate in the aggravation of the prognosis of these infections. The aim of this work was to study the epidemiological aspects of acquired bacteraemias in ICU and the responsible germs sensitivity, to determine strategies of adequate antimicrobial treatment. During the period of study, 31 positive blood cultures collected from 19 patients were considered to be true bacteraemias, giving an incidence rate of 6.3 for 100 admissions. The mean age of our patients was 27.7 years old. There were 16 men and 3 women. Traumatology was the underlying pathology in 52.63% of cases. The origin of the infection was unknown in 84.2%. Flavobacterium spp was the most frequent germ (42%), followed by Pseudomonas aeruginosa (26.2%), and Staphylococcus negative coagulase (10.6%). Only one anaerobic germ was isolated. Flavobacterium spp and Pseudomonas aeruginosa were in general sensitive to most antibiotics used with the exception of aminosides. Staphylococci negative coagulase were methi - resistant. The sensitivity of the anaerobic germ was not tested. The antimicrobial treatment was adapted in 84.2% of cases; the association ciprofloxacine-cefotaxime could be a good alternative in serious infections to Gram negative bacteria. The global death rate among our patients was 42%. The death was directly related to bactereamia in only 15.3% of cases. The existing committee for nosocomial infections control should be more effective in our hospital. The role of this committee is to carry out microbiological surveillance, to recommand and make sure of the application of preventive measures against nosocomial infections, to promote the accessibility of antibiotics such as imipeneme, aztreonam, ceftazidime, vancomycine...., and to propose an appropriate antimicrobial treatment strategy; these measures could reduce notably the morbidity and mortality related to nosocomial infections in general and bactereamias in particular.

[Respiratory manifestations of malignant lymphomas: report of 5 cases]. / Les manifestations respiratoires des lymphomes malins: à propos de 5 cas.

In this study the authors report 5 cases of malignant lymphomas consisting in a Hodgkin's disease and 4 non Hodgkinian lymphomas. Patients aged from 16 to 55 years were 4 males and 1 female, consulting in Department of respiratory disorders of the University Hospital in Dakar, Senegal, West Africa, from 1986 thru 1992. Detoriation of the general status, cough, dyspnea and cervical adenopathy were remaked in all patients. Thoracic pain and syndrom of right pleurisy were diagnosed in one case of non Hodgkinian malignantlymphoma. X Ray exploration of the chest detected 4 cases of mediastinal adenopathies and 3 pleurisis in non Hodgkinian malignant lymphomas; and reticulonodular opacities of pulmonary basis in the Hodgkin's disease case. The diagnosis has been confirmed by pathologic anatomy studis of the biopsed ganglia. The endemic characteristic of tuberculosis in developing countries make necessary to evoke it in first of any adenopathy. When the clinical feature is atypical, a biopsy of ganglia must be performed to avoid diagnosis delay which could lead to agravate the prognosis of malignant lymphomas.

[Traumatic tracheobronchial rupture: importance of early respiratory resuscitation and bronchoscopy]. / Rupture trachéo-bronchique traumatique: intérêt de la réanimation respiratoire et de la bronchoscopie précoces.

Traumatic tracheobronchial rupture is a rare and serious complication of blunt chest trauma. Authors report the case of a 9 years old girl who was hit by a car. She presented to the admission, a respiratory distress with subcutaneous emphysema, hemoptysis, bilateral pneumothorax and pneumomediastinum. Apparently persistent pneumothorax in spite of clinic improvement after oxygenoterapy and pleural drainage, had made consider tracheobronchial rupture. The bronchoscopy achieved in emergency, had shown a low lesion of the trachea and a desinsertion of the left main bronchus. A right thoracotomy had permitted to repair the lesions. Post-operative outcome was good and authors insist in interest of early management.

[Vulvar cancers. Retrospective study of 23 cases at the Cancer Institute of Dakar]. / Les cancers de la vulve. Etude rétrospective à propos de 23 cas colligés à l'Institut du Cancer de Dakar.

The vulvar cancer is an uncommon disease which is beginning mostly on vulvar intraepithelial neoplasma and it keeps a very bad prognostic. The purpose of this study is to report the epidemiological, the anatomo-clinic and and to discuss the treatment. We tell about 23 vulvar cancer from 1956 to 1995 which were followed at the cancer Institut of Dakar. The mean age of patients is 47 years and they are on menopause in 78.6%. The most of the tumors are ulcerate (96%). The clinical investigation find according the staging of FIGO: 15 tumors (T2), 8 tumors (T3), 6 tumors (N1), 9 tumors (N2) and 1 tumor (M1b). The surgery is the principal treatment with 6 radical vulvectomy and 17 palliative vulvectomy. The surgery was associated with radiotherapy and chemotherapy. So the vulvar cancer is uncommon in our country and concern the young wives. The vulvectomy with lymphadenectomy is the principal treatment; the prognostic still very bad because the diagnostic is often later.

[Arterial pressure and body mass index of children and adolescents in a rural area of Thiadiaye, Senegal]. / Etude de la pression artérielle et de l'index de masse corporelle chez l'enfant et l'adolescent en milieu rural à Thiadiaye (Sénégal).

The purpose of this study is to assess the profile of blood pressure and body mass index of children and adolescents in a rural area in Africa. It is a prospective study concerning a sample of 465 children and adolescents in the district of Thiadiaye (Senegal). The ration boys/girls was 1.02. Blood pressure was higher in girls. The prevalence of hypertension was 5.1% for the children and 1.5% for adolescents. There was no significative variation in body mass index for children whereas we were noted an augmentation with age in adolescence. The parameters of corpulence are higher in girls in adolescence. The prevalence of obesity was 3% in children and 2.4% for adolescents. There was no correlation between blood pressure and body mass index. This study show many particularities in rural area as for as blood pressure and body mas index of children and adolescent are concerned.

[Survey of smoking in the rural area of Thiadiaye, Senegal]. / Enquête sur le tabagisme en milieu rural a Thiadiaye (Sénégal).

The objective of this article is to study the place of tobacco addiction in a rural area in Senegal. We have performed a transversal and domicillary study on a sample of adults and adolescents of the district of Thiadiaye (Senegal). The mean age of the studied population is 39 +/- 8.5 years (extremes: 12 and 100 years). The sex ratio is 0.85%. The prevalence of tobacco addict was 24.07%, 9% of the teenagers and 32% of the adults were smokers. Tobacco use was more frequent among men (89% 5%) than women (10.5%) (p < 10(-7)). The most common form was traditional tobacco: 62.1%. Cigarette was smoked in 14.4% of cases. The mean duration of tobacco use was 13 +/- -12.2 years. The mean consumption per day of traditional tobacco was 5.1 +/- 4, whereas the mean number of cigarettes per day is 12.3 +/- -7. Our study shows that tobacco occupies an important place in rural area in Senegal where coexist with traditional habits, a modern tobacco use represented by cigarette smoking.

Cclinical study of vscular risk factors in the adult in the Thiadiaye rural environment. / Etude clinique des facteurs de risque vasculaire chez l'adulte en milieu rural à Thiadiaye.

Authors report the results of a prospective study in a sample of the district of Thiadiaye, a rural area in Senegal. They studied blood pressure, body mass index and waist-to-hip ratio of 329 adults. The mean systolic blood pressure is 123 +/- 24.3 mm Hg and the mean diastolic blood pressure is 71.7 +/- 13.2 mm Hg. There is a positive correlation between blood pressure and age (p < 10(-9)). The prevalence of hypertension is 20.18% and one can note a female predominance (21% for women versus 18% for men). The mean body mass index is 21.1 +/- 10.6. There is no correlation between corpulence and age. Conversely, the body mass index is higher in female in all age groups (p < 10(-7)). The prevalence of obesity is 5%. Abdominal fat distribution is 41.6%: 64% for women and 9.7% for men (p = 0.003).

With a sample of 40 patients, the authors conducted a prospective case-control study on the feasibility of differed autologous blood transfusion at Point "G" National Hospital in Bamako, Mali. The method has been accepted by all the patients. No clinical nor biological trouble has been reported by the patients themselves. The authors recommend the use of autologous blood transfusion by other hospital units and the development of regulations governing its implementation.

Transfusion autologue différée à l'Hôpital du Point G à Bamako: Etude prospective portant sur 40 observations à l'Hôpital du Point G de Bamako

"Sur un échantillon de 40 patients; les auteurs ont réalisé une étude prospective cas-témoins sur la faisabilité de la transfusion autologue différée à l'Hôpital National du point G de Bamako (Mali). La technique a été acceptée par la totalité des patients. Elle n'a pas entrainé de troubles cliniques ou biologiques pouvant influer sur les suites post-opératoires ; le surcout de la technique a été négligeable et n'a pas été pris en charge par les patients. Les auteurs recommandent une adoption de l'autotransfusion différée par d'autres formations sanitaires ainsi que sa règlementation."

Le syndrome de Klippel-Trenaunay : premiere description au Mali; a propos de 7 cas observes dans le service de chirurgie de l'Hopital du Point G; Bamako

Les auteurs rapportent pour la premiere fois au Mali une serie de 7 cas de syndrome de Klippel-Trenaunay. Les anomalies les plus frequemment rencontrees sont les varices et l'allongement et/ou l'hypertrophie du membre; la rarete des troubles dermatologiques pourrait etre liee a la discretion de certaines lesions cutanees chez le sujet noir. Ils passent en revue les differentes complications et insistent sur les nombreuses formes frustres qui justifient la recherche systematique du syndrome chez certains individus; surtout ceux porteurs de troubles dactyliques
