RESUMO

AIM: To determine the frequency of the surgery wound infection, its favoring factors, causative germs and its antibiotic treatment of choice in the surgery "A" department of the University Hospital Point G. METHOD: In a retrospective descriptive study over a 6-month period in the surgery "A" department of the University Hospital Point G, we enrolled all patients who underwent surgery necessitating at least 48 hours of hospital admission during our study period and in conformity with the Atlanta CDC criteria. Surgery patients with less than 48 hours postoperative hospital stay and those admitted to the hospital without surgery were not included.After the surgery, the nature and location of the infection have been clarified. In this work, ethical considerations have been respected and there is no conflict of interest. RESULTS: Two hundred and sixty-five (n=265) patient files were collected including 24 cases of surgery wound infection (a hospital frequency of 9%. The average age was 41.41 years (y.o) old with extremes of 7 y.o and 102 y.o. The sex ratio was 0.9 in favor of women. The commonly studied pathologies were digestive surgery in 52.8%, gynecological surgery in 24.5%, etc… Patients were seen in regular outpatient surgery visits in 75.8% and surgical emergencies in 24.2%. Of the patients urgently admitted, 26.5% presented an ISO; for those received in ordinary consultation it was 3.48%. Fifteen (15) cases were classified ASA III and two (2) ASA II. Based on the Altemeier classification, surgery was clean in 66.8% of our patients, contaminated clean in 12.4%, contaminated in 12.1%, and dirty in 8.7% (including half resulting in surgery wound infection). In total, 79% of patients whose surgeries lasted more than two (2) hours presented a surgery wound infection. Postoperative infection of patients was superficial in 58.3% and deep in 33.3%. In 8.3% of cases, it was a space infection. At the cytobacteriological examination of the pus from the operative site, Escherichia coli (E. coli) was the most common germ with 58.3%. E. coli was sensitive to amoxicillin-clavulanic acid in 57.14%. Surgically, a re-intervention was performed in 20.8% of cases, a secondary suture in 12.5%, and a single dressing in 66.7%. The average postoperative stay was 6.5 days with extremes of 2 days and 69 days. In 3 months postoperatively we recorded 4 cases of death. CONCLUSION: The surgery wound infection constitutes a major complication in a surgical environment starting with surgical act itself.Particular emphasis should be placed on prevention, which will reduce the risks of ISO occurrence.


BUT: déterminer la fréquence des infections du site opératoire (ISO), les facteurs favorisants la survenue des ISO, les germes responsables et les antibiotiques actifssur les infections du site opératoire dans le service chirurgie « A ¼ du CHU du Point G. MÉTHODE: Il s'agissait d'une étude rétrospective et descriptive sur une période de 6 mois réalisée dans le service chirurgie « A ¼ du CHU du Point G. Ont été inclus tous les patients ayant subi une intervention chirurgicale pendant cette période et hospitalisés au moins 48 heures après, et qui ont répondu aux critères du CDC d'Atlanta. N'ont pas été inclus, les patients opérés dont le séjour post opératoire a été inférieur à 48 heures, les patients hospitalisés dans le service mais non opérés, et ceux opérés dans le service et non hospitalisés. En postopératoire la nature et le siège de l'infection ont été précisées. Dans ce travail les considérations éthiques ont été respectées et il n'y a pas de conflit d'intérêt. RÉSULTATS: deux cent soixante-cinq dossiers de patients ont été colligés dont 24 cas d'ISO soit 9% des cas. L'âge moyen a été de 41,41 ans avec des extrêmes de 7ans et 102 ans. Le sex ratio a été de 0,2 en faveur des femmes. Les principales pathologies étudiées ont été la chirurgie digestive dans 52,8%, la chirurgie gynécologique dans 24,5%. La majorité des patients ont été reçus en consultation ordinaire dans 75,8% des cas, et en urgences dans 24,2 %. Parmi les patients reçus en urgence 26,5% ont présenté une ISO ; pour ceux reçus en consultation ordinaire elle a été de 3,48%.Parmi les patients infectés 15 étaient classés ASA III et 2 ASA II. Selon la classification Altemeier, la chirurgie propre a occupé 66,8% des patients, la chirurgie propre contaminée 12,4%, la chirurgie contaminée 12,1%, et la chirurgie sale 8,7%. Parmi les patients opérés de chirurgie sales 50% ont présenté une ISO.L'ISO était présente chez 79% des patients ayant effectué plus de 2 heures d'intervention.En postopératoire l'infection était superficielle chez 58,3% des patients, et profonde chez 33,3% des patients. Dans 8,3% des cas, il s'agissait d'une infection d'espace. A l'examen cytobactériologique du pus Escherichia coli (E coli) avec 58,3% a été le germe le plus fréquent sur le site opératoire. E coli était sensible à l'association amoxicilline - acide clavulanique dans 57,14%. Sur le plan chirurgical une réintervention a été réalisée dans 20,8% des cas, une suture secondaire dans 12,5%, et un pansement seul dans 66,7%. La durée moyenne de séjour post opératoire était de 6,5 jours avec des extrêmes de 2 jours et 69 jours. En 3 mois postopératoire nous avons enregistré 4 cas de décès. CONCLUSION: L'ISO constitue une complication majeure en milieu chirurgical compromettant l'acte chirurgical. Un accent particulier doit être mis sur la prévention qui diminuerai les risques de survenue de l'ISO.

RESUMO

The aim of this work was to describe the epidemiological and therapeutic aspects of surgical diseases in patients in pre-trial detention at Camp 1 of Gendarmerie in Bamako (Mali) and to evaluate the medico-legal aspects of this management. METHOD: It was a descriptive retrospective study over a three year period (January 2014 to December 2016). Included were all detainees who had stayed at the Bamako Gendarmerie Camp 1 detention center and whose medical care had required a surgical procedure, performed or coordinated by the staff of the garrison. RESULTS: Clinical records of 42 inmates-patients were collected. Their average age was 36.5 years varying between 24 years and 73 years and all of them were men. The average length of pre-trial detention was 17 months varying from 16 days to 39 months. On arrival, 35.7% of the detainees (15/42) benefited from an initial examination by a garrison infirmary health worker. Among them, 46.7% (7/15) required urgent surgical procedures. The average time to access care was 4 hours varying from to 6 days. Consent to care was obtained from 54.8% (23/42) of prisoners prior to any medical procedure. Traumatic conditions were the main etiologies of emergency care. Systematic screening for communicable diseases and exit visit at discharge were not performed. Over the 3 yearlong study period, no case of death was recorded. CONCLUSION: The medical and surgical management of these detainees has enabled the staff of the garrison infirmary at Camp 1 to acquire knowledge and skills in detention health. The impact of this acquisition is reflected as an improvement in the quality of care over the years.


OBJECTIFS: décrire les aspects épidémiologiques, thérapeutiques des affections chirurgicales chez les patients en détention préventive au Camp 1 de gendarmerie de Bamako (Mali) et analyser les aspects médico-légaux. MÉTHODE: L'étude était rétrospective descriptive sur une période de trois ans (janvier 2014 à décembre 2016), réalisée chez les patients au cours de leur détention préventive au Camp 1 de gendarmerie de Bamako. Ont été inclus, tous les détenus ayant séjournés au centre de détention du Camp 1 de gendarmerie de Bamako et dont la prise en charge médicale avait nécessité un acte chirurgical, réalisé ou coordonné par l'équipe soignante de l'infirmerie de la dite garnison. RÉSULTATS: Les dossiers cliniques de 42 patients ont été colligés. L'âge moyen était de 36,5 ans avec des extrêmes de 24 ans et 73 ans. Tous étaient de sexe masculin.La durée moyenne de la détention préventive était de 17 mois avec des extrêmes de 16 jours et 36 mois.A leur arrivée 35,7% des détenus (N=15/42) ont été vus par un agent de santé, parmi lesquels 16,6% (N=7) avaient besoin de gestes chirurgicaux en urgence. Le délai moyen d'accès aux soins était de 4 heures avec des extrêmes de 6 jours. Le consentement aux soins avait été obtenu dans 54,8% (N=23/42). Les affections traumatiques ont été les principales étiologies des soins en urgence. Aucun dépistage systématique d'affections contagieuses, ni de visite de sortie. Aucun décès n'avait été enregistré pendant les 3 années de l'étude. CONCLUSION: Les affections chirurgicales ne sont pas rares en détention au camp1 de gendarmerie de Bamako. Le déficit de prise en compte des aspects médicolégaux influence sur la qualité des soins aux détenus.

RESUMO

AIM: Our aim was to evaluate the diagnosis and therapeutic aspects of the amoebic liver abscesses in the surgery «A¼ department of the University hospital Point "G". PATIENTS AND METHODS: Were included in this study, patients admitted to the surgery «A¼ department for amoebic liver abscess confirmed by a positive amoebic serology and the chocolate appearance of bacteria-free pus. Bacterial liver abscesses were not included into this study. RESULTS: Over a 10-year period, 52 cases of patients diagnosed with amoebic liver abscess were collected in the department. There were 41 men and 11 women, with a sex ratio of 3.7. The mean age was 37.8 years old with extremes of 15 and 66 years. The most represented professions were farmers (36.5%) followed by salesmen (26.7%) and students (11.5%). The average outpatient visit delay time was 18.5 days with the extremes of 5 and 34 days. The most frequent clinical signs were pain in the right hypochondrium (86.5%), fever (78.8%) and hepatomegaly (61.5%). Abdominal ultrasound showed a single located abscess in 44 patients (84.6%) and these abscesses were localized in the right hepatic lobe in 34 patients(65.4%). The average volume of the abscess was 366.5 cm3 with the extremes of 36 cm3 and 1580 cm3. Amoebic serology was positive in 38 patients (80.9%). Cytobacteriological analysis of pus in 37 patients (71%) was negative. Patients underwent an ultrasound assisted needle aspiration of pus in 65.4% he. Laparotomy and a laparoscopic approach were performed in 7.7% and in 5.8%, respectively. The clinical course was uneventfulin 94.2%. The mean hospital stay duration was 16.5 days with the extremes of 4 and 29 days. No death was recorded during hospitalization. CONCLUSION: Amoebic liver abscess is an uncommon pathology in a surgical setting. Abdominal ultrasound andechography guided liver puncture allowed the diagnosis. Laparoscopic approach minimizes the burden of the laparotomy.


BUT: Le but de cette étude était d'évaluer les aspects diagnostiques et thérapeutiques des abcès amibiens du foie dans le service de chirurgie " A " du CHU du Point G. PATIENTS ET MÉTHODES: Ont été inclus dans cette étude, les patients admis dans le service de chirurgie "A" pour abcès amibien du foie sur la base de la positivité de la sérologie amibienne, de l'aspect chocolat du pus et de l'absence de bactéries dans le pus. Les abcès bactériens ont été exclus de cette étude. RÉSULTATS: En 10 ans, 52 dossiers de patients diagnostiqués pour abcès amibiens du foie ont été colligés dans le service. Il s'est agi de 41 hommes et de 11 femmes soit un sex-ratio de 3,7. L'âge moyen des patients a été de 37,8 ans avec des extrêmes de 15ans et 66 ans. Les professions les plus représentées ont été les cultivateurs (36,5%), les commerçants (26,7%) et les élèves et étudiants (11,5%).Le délai moyen de consultation a été de 18,5 jours avec des extrêmes de 5 jours et 34 jours. Les signes cliniques les plus fréquents ont été la douleur de l'hypochondre droit (86,5%), la fièvre (78,8%) et l'hépatomégalie (61,5%). L'échographie abdominale a objectivé un abcès unique dans 44 cas (84,6%) et l'abcès a été localisé dans le lobe hépatique droit dans 34 cas (65,4%). Le volume moyen de l'abcès était de 366,5cm3 avec des extrêmes de 36 cm3 et 1580cm3. La sérologie amibienne a été positive dans 80,9% (n = 38). La culture a été stérile à l'analyse cytobactériologique du pus dans 37 cas (71%). Une ponction évacuatrice écho-guidée a été réalisée dans 65,4% des cas. La procédure chirurgicale a consisté à réaliser une laparotomie dans 7,7% des cas et un abord coelioscopique dans 5,8%. Les antibiotiques utilisés ont été le métronidazole par voie intraveineuse chez tous les patients, associés à la céftriaxone dans 78,8% (n=41). L'évolution clinique a été favorable dans 94,2%. La durée moyenne d'hospitalisation a été de 16,5 jours avec des extrêmes de 4 jours et 29 jours. Aucun décès n'a été constaté pendant l'hospitalisation. CONCLUSION: L'abcès amibien du foie est une pathologie peu fréquente en milieu chirurgical. L'échographie abdominale et la ponction écho-guidée ont permis de poser le diagnostic. Le traitement par abord coelioscopique minimise les inconvénients de la laparotomie.

RESUMO

The aim of this study was to evaluate the surgical treatment of goiter in the «A¼ surgical department of the Point G University Hospital in Bamako. PATIENTS AND METHODS: This was a retrospective and descriptive study in the «A¼ surgical department of the Point G University Hospital from January 2007 to August 2014. Included in the study were all the patients operated for goiter. The patients who underwent surgery for other thyroid diseases were not selected. Postoperatively patients were followed for one year. The sociodemographic, clinical, para-clinical, therapeutic aspects and the postoperative course were the study parameters. Data analysis was performed on SPSS 21. The Chi square test was used for statistical analysis. A p-value inferior to 0.05 was considered statistically significant. RESULTS: A total of 378 patients' records were collected. Thyroidectomy represented 6.2% (378 cases) over 6027 operations. The mean age was 41.29 years with a standard deviation of 13.58. Extremes were 3 and 85 years. The sex ratio was 7.22 in favor of women. The frequent reason for consultation was due to antero-cervical tumor with 97.07% of cases (n = 367). We identified 118 cases (31.22%) of goiter in cooled hyperthyroidism patients, 211 cases (55.82%) of euthyroid goiter, 7 cases (1.85%) of the thyroid neoplasia and one case (0.3%) of hypothyroidism goiter. Pathological histology helped to highlight a micro-vesicular macro adenoma in 16.1% of cases (61 patients); adenocarcinoma in 0.7% of cases (3 patients) and papillary carcinoma in 1.1% of patients (4 patients). The patients classified as ASA I and ASA II represented the majority with respectively 248 cases (65.60%) and 120 cases (31.74%). The most performed surgical techniques were subtotal thyroidectomy (n=181; 49.7%), the isthmo-lobectomy (126; 33.3%), total thyroidectomy (n=11; 2.9%) and sternotomy in one case of endothoracic goiter. Intraoperative complications were marked by hemorrhage in 12.7% of cases (45 patients). The postoperative one month follow up was uneventful in 91.79% (n = 347) and transient recurrent nerve injury was found in 2% of cases (1 patient). In one year follow up the postoperative outcome was good in 94.17% (n = 356) of patients. The mean hospital stay was 4.18 days. Six deaths were recorded (1.7%). CONCLUSION: Goiter surgery is relatively common in the surgery 'A' department of the Point G University hospital. Good patient preparation and a better postoperative monitoring could help to minimize postoperative complications.


Le but de ce travail était d'évaluer la prise en charge chirurgicale des goitres dans le service de chirurgie «A¼ du CHU du Point G, à Bamako. PATIENTS ET MÉTHODE: Il s'agissait d'une étude rétrospective et descriptive menée dans le service de chirurgie «A¼ du CHU du POINT G, de Janvier 2007 à Août 2014. Ont été inclus dans l'étude tous les patients reçus et opérés pour goitre. N'ont pas été retenus les patients opérés pour un kyste du tractus thyréoglosse, les abcès cervicaux, les traumatismes du cou, et les dossiers incomplets. Les patients ont été suivis pendant un an en postopératoire. Les aspects sociodémographiques, cliniques, para cliniques, thérapeutiques, ainsi que les suites opératoires ont été les paramètres d'étude. L'analyse des données a été effectuée sur le logiciel SPSS version 21. Le test statistique utilisé a été le Khi 2. Une valeur de p< 0,05 a été considérée comme statistiquement significative. RÉSULTATS: Un total de 378 dossiers de patients ont été colligés. La thyroïdectomie a représenté 6,2% (378 cas) sur 6027 interventions. L'âge moyen était de 41,99 ans avec un écart type de 13,58. Les extrêmes étaient de 3 ans et 85 ans. Le sex ratio était de 7,22 en faveur du sexe féminin. La tuméfaction antero-cervicale était le motif de consultation le plus fréquent avec 97,07% des cas (n= 367). Nous avons recensé 118 cas (31,22%) de goitre en hyperthyroïdie refroidie, 211 cas (55,82%) de goitre euthyroïdien, 7 cas (1,85%) de néoplasie de la thyroïde, un cas (0,3%) d'hypothyroïdie. L'histologie a permis de mettre en évidence un adénome micro-macro vésiculaire dans 16,1% des cas (61 patients); un adénocarcinome dans 0,7% des cas (3 patients); un carcinome papillaire dans 1,1% des cas (4 patients). Les patients de classe ASA I et ASA II étaient majoritaires avec respectivement (248 cas; 65,60%, et 120 cas; 31,74%). Les techniques chirurgicales les plus réalisées étaient la thyroïdectomie subtotale (181; 49,7%), l'isthmo-lobectomie (126; 33,3%), une thyroïdectomie totale (11; 2,9%); une sternotomie dans un cas de goitre endothoracique. Une hémorragie était notée dans 12,7% des cas (45 patients) en peropératoire. Les suites opératoires à un mois étaient simples dans 91,79% (n=347) et une lésion transitoire du nerf récurrent dans 2% des cas (1 patient). Les suites opératoires à un an étaient simples chez 94,17% (n=356) des patients. La durée moyenne d'hospitalisation était de 4,18 jours. Six décès ont été enregistrés (1,7%). CONCLUSION: La chirurgie des goitres est relativement fréquente dans le service de chirurgie «A¼ du CHU du POINT G. Une bonne préparation et une meilleure surveillance post opératoire pourraient aider à minimiser les complications post opératoires.

RESUMO

AIM: to evaluate the contribution of laparoscopic surgery in the management of chronic abdominal pains of unspecified etiology. METHODS: A retrospective descriptive study was conducted over a period of 49 months (March 2008 to March 2012), in the surgery A service of the Point G university hospital. RESULTS: 52 patients suffering from chronic abdominal pain for 3 months have been listed. There were 36 women and 16 men, with a sex-ratio of 2.25. The pathologies found in laparoscopy were: 16 cases of adherences, 16 cases of gynaecological diseases, 6 cases of chronic appendicitis, 5 cases of chronic cholecystitis, 6 cases of abdominal tumors and 3 cases of intrauterine contraceptives in abdomen. Conversion to laparotomy was not made and mortality was null. No lesion was found in 11.54% of cases. The mean duration of hospitalization was 2 days. The duration of follow-up of the patients was 18 months with a minimum of 6 months and a maximum of 24 months. No painful symptomatology was found in 6 months in 88.46% of the cases. Persistent stomach pains were found in 3% of the cases. 8.54% of the patients had an improvement of symptomatology. CONCLUSION: Chronic abdominal pains put a diagnosis problem in surgery. Laparoscopy is a reference technique to diagnose this pain and to discuss them.


BUT: évaluer l'apport de la chirurgie laparoscopique dans la prise en charge des douleurs abdominales chroniques d'étiologie indéterminée. MÉTHODE: Il s'agissait d'une étude rétrospective et descriptive sur une période de 49 mois (mars 2008 à mars 2012), dans le service de chirurgie A du CHU du point G. RÉSULTATS: 52 patients souffrant de douleur abdominale depuis 3 mois ont été recensés. Il s'agissait de 36 femmes et 16 hommes soit un sex-ratio de 2,25. Les pathologies retrouvées à la laparoscopie étaient : 16 cas d'adhérences, 16 cas d'affections gynécologiques (hydrosalpinx, kystes dermoïdes, salpingites, endométriose externe), 6 cas d'appendicites chroniques, 5 cas cholécystites chroniques, 6 cas de tumeurs abdominales et 3 cas de stérilet intra-abdominal. Aucune conversion n'a été effectuée. La mortalité était nulle. Aucune lésion n'a été retrouvée dans 11,54% des cas (N=6cas). La durée moyenne d'hospitalisation était de 2 jours. La durée moyenne de suivi des patients était de 18 mois avec des extrêmes de 6 mois et 24 mois. 6 mois après l'intervention aucune symptomatologie douloureuse n'a été retrouvée dans 46 cas (88,46%), des douleurs abdominales persistantes ont été retrouvées dans 3% (N=2cas) et 5 patients (8,54%) avaient une nette amélioration de la symptomatologie douloureuse. CONCLUSION: Les douleurs abdominales chroniques posent un problème de diagnostic en chirurgie. La laparoscopie est une des techniques de référence indiquée pour diagnostiquer et traiter ces douleurs.

RESUMO

OBJECTIVE: The aim was to evaluate the results of surgical treatment of occlusion of the sigmoid colon due to volvulus. PATIENTS AND METHODS: This was a retrospective study from 1996 to 2010 of all patients undergoing surgery for sigmoid volvulus in surgical wards of the University Hospital of Bamako. RESULTS: A total of 417 patients were identified including 379 men and 38 women. The mean patient age was 45.7 ± 18.3 years. The general condition of the patients was good in 70.5% and altered in 29.5% of cases. Colonic necrosis was present in 80 patients (19.2%). Single-stage resection with immediate anastomosis was performed in 149 patients (35.73%). Two-stage surgery was performed in 268 cases (64.27%). The initial stage of the two-stage procedure was colostomy in 167 cases and simple detorsion in 101 cases. The surgical approach had an impact on mortality in patients who were in poor general condition. Single-stage surgery resulted in higher mortality (12/149; 8.05%) than two-stage surgery (5/268; 1.87%), and the difference was statistically significant (P=0.0005). CONCLUSION: Single-stage surgery for sigmoid volvulus carries a high risk of death when it is performed in patients with poor general condition. Indications for surgery must take into account the patient's general condition and the viability of the torsed sigmoid colon.

RESUMO

OBJECTIVE: To evaluate the short-term results of the treatment of malignant gastric tumors. PATIENTS AND METHODS: A 3-year retrospective study from january 2007 to december 2010 was conducted in the Surgery "A" department of the Point G Teaching Hospital. The clinical records of 84 patients with gastric cancers were collected. Included in this study were patients who underwent surgery for malignant gastric tumors confirmed by histology. Patients who did not undergo surgery and those who presented tumors of the cardia were not included in this study. RESULTS: The treatment consisted of a subtotal gastrectomy with ganglionic curettage taking out the first and the second relays in 33 patients (39.28%), total gastrostomy in 3 patients (3.57%), and the remaining 48 patients (57.14%) underwent gastro-entero anastomosis. Morbidity was 10.7%, represented by 7 cases of parietal suppuration and 2 cases of evisceration. Mortality rate was 11.11%, due to poor general condition of the patients. The global 1-year survival rate was 36.9%. The one and two-year survival rates after subtotal gastrostomy were 93.9% and 75.75%, respectively. No survival case was noticed one year after total gastrectomy and gastric enteric anastomosis. CONCLUSION: Partial gastrectomy with ganglionic curettage when possible associated with an early diagnosis could allow a sharp improvement of the gastric tumors' survival rate.


BUT: évaluer les résultats à court terme de la prise en charge des tumeurs malignes gastriques. PATIENTS ET MÉTHODES: Il s'agissait d'une étude rétrospective sur une période de 3 ans (janvier 2007 à décembre 2010) dans le service de chirurgie «A ¼ du CHU du Point G. Les dossiers cliniques de 84 malades atteints de cancers gastriques ont été colligés. Ont été inclus dans l'étude les malades opérés pour tumeurs malignes gastriques confirmées à l'histologie. Les malades non opérés et ceux présentant de tumeurs du cardia n'ont pas été inclus dans l'étude. RÉSULTATS: Une gastrectomie subtotale était réalisée chez 33 patients (39,28%) avec curage ganglionnaire emportant le premier et le deuxième relais, 3 gastrectomies totale (3,57%) et le reste du traitement a consisté en une gastro-entero-anastomose chez 48 malades (57,14 %). La morbidité était de 10,7 % représentée par 7 cas de suppuration pariétale, et 2 cas d'éviscération. Le taux de mortalité a été de 11,11% liée au mauvais état général des malades. Le taux de survie global à 1 an était de 36,90%. Le taux de survie à 1 an après gastrectomie subtotale était de 93,9%, et 75,75 % à 2 ans. Aucun cas de survie n'était enregistré à 1 an après gastrectomie totale et gastro-entero-anastomose. CONCLUSION: La gastrectomie partielle avec curage ganglionnaire chaque fois que sa réalisation est possible associée à un diagnostic précoce pourrait permettre une nette amélioration du taux de survie des tumeurs gastriques.

RESUMO

AIMS: To determine the most frequent causes of the digestive perforations and to evaluate the surgical procedures, the morbidity and mortality. PATIENTS AND METHODS: It was about a retrospective descriptive study, over 5 year's period in a visceral service of CHU du Point G, Bamako. Were included in the study all the patients operated for digestive perforation and hospitalized in the service of surgery "A". Were not included in the study patient operated not presenting a digestive perforation. Per operational etiologies of the perforations and their frequency were determined, as well as the morbidity and morbidity and mortality. RESULTS: Files of 202 patients were collected. The average age of the patients was 28.3 ± 15.5 years with extremes of 6 and 71 years. The frequency of digestive perforations was higher in the age from 11 to 20 years (29.7%). The average time of consultation was of 7± 6 days. Abdominal pains, nauseas and vomiting, matter and gas stop (48.5%) were the most current functional signs. A "wood belly" abdomen was found in 72,3% of the cases. The radiography of abdomen without preparation found a diffuse greyness (64.7%), a pneumoperitoine (30.7%). A double antibiotic therapy was made in all the cases. A median laparotomy was practiced in 98,5%, and laparoscopy in 3 cases (1.5%). A single perforation was found among 172 patients (85,1%). Morbidity, all confused causes, was made of 30 cases of parietal suppurations (14.8%). Total mortality was 74%. According to aetiologies it was 10.3% in the typhic perforations, 4.6% in the appendicular perforations and 4.9% in the perforations of gastroduodenal ulcers. CONCLUSION: The most frequent aetiologies of digestive perforation in our context were the typhoid fever, acute appendicitis and the gastroduodenal ulcer. The résection - joining and peritoneal toilet were the most practised procedure. The main factor of bad outcome remains the diagnostic delay burdening morbidity and mortality.

RESUMO

GOAL: To assess the surgical therapy in goiter with hyperthyroidism in a surgical unit of CHU du Point-G. PATIENTS AND METHODS: A retrospective study was conducted, concerning 131 patients having undergone a thyroidectomy for goiter with hyperthyroidism from January 1st 1998 to December 31st 2007. RESULTS: The files of 131 patients were analysed. The average age of patients was 39.74 years, with 114 women and 17 men. The goiter in Basedow disease was the first indication for surgery in hyperthyroidism (48 cases; 36.6%) followed by toxic adenoma (39; 29.8% of the cases) and toxic multinodular goiter (38; 29% of cases). Ninety patients had a subtotal thyroidectomy (68.7% of cases). One total thyroidectomy (0.8%), 39 isthmolobectomies (29.7%) and one isthmectomy (0.8%) were carried out. Anatomohistology showed 67.1% of colloid benign tumours, and 8 cases of cancers (6.2% of the cases). Early postoperative follow ups were due to hemorrhage (2 cases; 1.5%) and 3 cases of dysphonia (2.5%). One patient died (0.8%). After six months, 3 cases of wound cheloide (2.5%), one case of dysphonia, and one case of hypothyroidism were noted. For 86 patients (71.1%) the postoperative follow up was simple. CONCLUSION: Surgery remains a treatment of choice for hyperthyroidism goiter. Other options are too expensive or not available.


BUT: évaluer la prise en charge chirurgicale des goitres hyperthyroïdiens dans le service de chirurgie « A ¼ du CHU du Point-G. PATIENTS ET MÉTHODES: Il s'agissait d'une étude rétrospective descriptive portant sur tous les patients ayant subi une thyroïdectomie pour goitre hyperthyroïdien sur la période allant du 01 Janvier 1998 au 31 Décembre 2007. RÉSULTATS: Au total 131 malades ont été recensés, soit 114 femmes et 17 hommes. La moyenne d'âge des patients était de 39,74 ans avec un écart type de 11,72. Les indications chirurgicales les plus courantes étaient les goitres de la maladie de Basedow (48; 36,6% des cas) les adénomes toxiques (39; 29,8% des cas) et les goitres multinodulaires toxiques (38; 29% des cas). La technique opératoire a été la thyroïdectomie subtotale (90; 68,7%), l'isthmolobectomies (39; 29,7%), la thyroïdectomie totale (1; 0,8%), et l'isthmectomie (1; 0,8%). L'examen histo-anatomo-pathologique des pièces opératoires a permis de mettre en évidence un taux élevé de tumeurs épithéliales bénignes (67,1%), ainsi que 8 cas de cancers (6,2%). Les suites opératoires de J0 à J3 ont été marquées par deux cas d'hémorragie (1,5%) et 1 décès (0,8%). A six mois postopératoire 3 cas de cicatrices chéloïdes (2,5%), 3 cas de dysphonie persistante (2,5%) et un cas d'hypothyroïdie biologique (0,8%) ont été enregistrés. Pour 86 malades (71,1%) les suites ont été simples. CONCLUSION: La chirurgie reste une des options privilégiées pour le traitement des goitres hyperthyroïdiens dans notre contexte. Les autres options sont onéreuses ou non disponibles.

RESUMO

The purpose of this report was to determine the frequency of hysterectomy and describe its indications and outcomes. A retrospective, descriptive study related to active hysterectomy of was conducted at the reference health centre of commune V in Bamako, Mali from January 1st, 2004 to December 31st, 2008. All hysterectomy patients with complete medical files were included. A total of 172 files were identified including 152 that were complete. Hysterectomy accounted for 1.38% of all interventions during the study period. The procedure was carried out in emergency in 0.14% and electively in 13.39%. Mean patient age was 47.9 +/- 11.7 years; 89 patients were older than 45 years. The indications for hysterectomy were complicated uterine fibroids in 82 patients, genital prolapse in 44, adenomyosis in 10, obstetrical hysterectomy in 13 and cervical dysplasia in 3. The abdominal route was used in 100 patients (65.8%) and the vaginal rout in 52 (34.2%). The duration of the procedure and hospital stay was longer after hysterectomy by the abdominal (p<0.05). Perioperative complications were observed in 17% of patients after abdominal hysterectomy versus 7.69% after vaginal hysterectomy. Two maternal deaths due to hemorrhagic shock were observed after obstetrical hysterectomy. Hysterectomy is a frequent intervention that is not without complication risks. Choice of route depends on the indication and skill of the operator. Although endoscopic surgery is still difficult to perform in developing countries, development of vaginal hysterectomy is necessary to reduce perioperative complications.

RESUMO

AIM: To determine the hospital frequency, identify the risks factors and evaluate the mortality of the early postoperative complication. PATIENTS AND METHODS: It was about a prospective study done from January first to May 31st 2006. All children from 0 to 15 years old operated in settled or urgent surgery and follow in the service were concerned of this study. RESULT: We brought together 47 cases of complication in 40 patients on a total of 631 children operated in five months. The average age of our patients was of 51.9 months +/- 47.4. The average period of hospital stay was of 4.3 days +/-3.12. A germ was found in the pus in 13 patients. A lung opaqueness was found in three patient's and a germ was present in the urine in 3 also. The average period of appearance of complications was of 7.7 days +/-1.3. The infection of the operating site occupied 2.5%, evisceration 1.1%, haematoma 0.9%, digestive fistula 0.3% and postoperative occlusion 0.15%. The death rate was 1.9%. CONCLUSION: The type of surgery, the mode of recruitment, the duration and conditions of the hospital stay were the factors of the postoperative complications.

RESUMO

We present a retrospective study of eight cases of vulvar bilharziasis who attended our institution for dermatological visit from 1998 to 2001. The mean age was 11 years old (range: 7 to 13). The clinical examination found wart like or ulcerated nodules, papules and/or diffuse infiltration. All the lesions were located on the left side of the vulvae (labium) and/or the groin. S. haematobium was the only causative agent identified in all specimens. The exclusive left side location of the lesions reported here has never been mentioned in the previous studies. The physiopathology of this finding is possibly linked to factors similar to those explaining the Cockett syndrome. Further examinations, including ultrasonography of the pelvis in larger series, are needed to learn more about the mechanism of this clinical entity.

RESUMO

The identification of one or several hypochromic patches (HP) on the skin is a key stage in the diagnosis of leprosy on dark skin. However, HP are often caused by other disorder than leprosy. A study to determine the prevalence and causes of HP among children was carried out in a rural area of Mali in November 2001. All children under 15 years of age in two villages in an endemic area were screened by two dermatologists. Among the 1729 children seen, HP were identified in 71 patients, with a prevalence of 4.1%. The most common cause of HP was tinea versicolor, which was present in 39.4% of children with HP, followed by pityriasis alba in 31%, naevus achromicus in 24% and vitiligo in 5.6%. No case of leprosy was detected. Our study raises several points with practical consequences for the detection of leprosy cases: the high prevalence of non-leprous HP compared to leprosy, the reliability of the clinical diagnosis of leprosy, and the role of general health care workers in the detection of leprosy cases. Helping those who should be involved in that detection in distinguishing true cases from other hypochromic disorders appears to be a priority.

RESUMO

The effects of exposure to placental malaria infection on newborn immunological responses, in particular Th1/Th2 cytokines and antigen-presenting cell (APC) function, were compared between cord blood mononuclear cells (CBMC) from parasitized and non-parasitized placentas of Gambian women. Cells were analysed in vitro for their ability to respond to mitogens [phorbol myristate acetate (PMA)/ionomycin, phytohaemagglutinin (PHA)], a malaria-unrelated test antigen [purified protein derivative of Mycobacterium tuberculin[purified protein derivative (PPD)] and Plasmodium falciparum schizont extracts. Mitogens induced strong proliferation and secretion of high concentrations of both IL-13 and sCD30 in CBMC from both groups. Conversely, significantly lower amounts of IFN-gamma were induced in the parasitized group in response to low doses of PHA. Protein antigens induced very low amounts of all tested cytokines, in particular IFN-gamma. However, a significantly higher release of sCD30 was observed in response to schizont extracts in the parasitized group. Addition of LPS to activate APC to low doses of PHA or schizont extracts increased the IFN-gamma production in both groups but levels remained lower in CBMC from the parasitized group. This result correlates with the lower production of IL-12 found following lipopolysaccharide (LPS) stimulation in this group. Taken together, these data show that placental infection with P. falciparum affects Th1 differentiation and sCD30 priming of neonatal lymphocytes and that the probable mode of action is via APC.

RESUMO

INTRODUCTION: Noma is a necrotic stomatitis, frequent in undernourished children in tropical countries. Its occurrence in adults is extremely rare and has recently been described during AIDS. We report two new cases. OBSERVATIONS: The first patient, a 37 year-old farmer, consulted for a mutilating ulcer of the commissure of the right lip. The second patient, a 25 year-old woman, consulted for an ulcerating and necrotic tumefaction of the left cheek. Anamnesis reconstructed the chronology of the lesions and a cutaneous biopsy revealed non-specific ulcers. The status of health of both patients was poor and they both exhibited positive HIV serology. DISCUSSION: The diagnosis of noma is easy and based on clinical manifestations. The characteristic aspect is that of a mutilating ulcer of the face with conventional progression: tumefaction, followed by ulceration and finally elimination necrosis. This disease predominates in children. Its discovery in adults is a sign of poor prognosis because it may reveal an HIV infection at the AIDS stage. CONCLUSION: It is important to draw the attention of practitioners on the interest of performing HIV serology when confronted with an adult exhibiting a noma, and to evoke a noma when confronted with a tumefaction of the face rapidly progressing towards necrosis.

RESUMO

Practice of multidrug therapy in leprosy (combination Dapsone + Rifampicine + Clofazimine) established since 1981, has significantly reduced the incidence of the disease. However, immunosuppression due to treatment of multi-drugs therapy induced adverse reactions with glucocorticoid and the change in host immune response due to the leprosy itself, might increase the risk of parasitic infections. To test this hypothesis, we carried out a case-control study at the "Institut Marchoux" in Bamako. Stool and urine samples from all patients included in the study were examined for parasites identification. In addition, we performed thick and thin blood film to identify malaria infection and skin biopsy (snip) to detect onchocerciasis. A total of 121 cases of leprosy and 219 controls aged 10-84 years old were included in the study from March 1999 to February 2000. Sixty two percent (n = 121) of cases were treated with glucocorticoid. The prevalence of infection due to Entamoeba coli and Entamoeba histolytica were higher in cases than in controls (p = 0.02). The prevalence of infection due to hookworms was higher in cases than in controls. There was no difference of the infections to the other intestinal parasites. Three cases of cryptosporidiosis and one case of isosporosis were observed in leprosy group vs none in the control group. There was no significant difference between cases and controls with regard to prevalence of Schistosoma haematobium, Trichomonas vaginalis and Onchocera volvulus. The prevalence of Plasmodium falciparum was 4.9% (6/121) in the leprosy case and 7.8% (17/219) in the control group. In conclusion, despite the corticotherapy and immunosuppression due to leprosy, there was no difference in prevalence of pathogenic parasites. Entomoeba coli, Entamoeba histolytica which have significantly higher prevalence among the cases were not pathogen therefore there was no higher risk of severe intestinal parasitosis among the cases of leprosy. Treatment with glycocorticoid in patients with leprosy did not suggest any impact on the prevalence of this parasitic infections. In addition, multidrug therapy did not show any effect on the carriage of Plasmodium falciparum.

RESUMO

Essential oils from sweet basil, Ocimum basilicum, and African basil, O. gratissimum, (Labiatae) grown in Guinea were obtained by steam distillation. Following exposure of newly emerged adult beetles (Callosobruchus maculatus) to 12h of fumigation using pure essential oils at a dose of 25&mgr;l/vial, 80% mortality was recorded for O. basilicum, 70% for O. gratissimum and 0% in the control. A significant difference was observed between the responses of males and females with males exhibiting greater sensitivity. When 1g of aromatized powder was applied to adults, a 50% lethal concentration at 48h was found to be 65&mgr;l/g for O. basilicum and 116&mgr;l/g of O. gratissimum oils. The essential oils from the two plant species exhibited a significant effect both on the egg hatch rate and on the emergence of adults. The egg hatch rate was reduced to 3% with O. basilicum and 15% with O. gratissimum using an essential oil concentration of 30&mgr;l, whereas the egg hatch rate for the control was 95%. When compared with the control (97%), adult emergence dropped to 0% with O. basilicum and to 4% with O. gratissimum. Storage bioassays were run to assess the long-term effect of powders aromatized with essential oils of Ocimum. Complete protection was observed over 3 months starting at a dose of 400&mgr;l in the case of both oils. From a germination test, it was concluded that aromatized powders have no significant effect on the seed germination rate. After 5d, a rate of 88% germination was seen in seeds treated with aromatized powder and protected from insects, compared with 97% for untreated seeds that were not exposed to insects.

RESUMO

INTRODUCTION: We report a case of basidiobolomycosis (subcutaneous phycomycosis), an uncommon deep mycosis in the entomophtoromycosis group. CASE REPORT: A 12-year-old girl presented a deep skin infiltration involving the back and buttocks. Histology reported filamentous formations without septa surrounded by Splendore-Hoepple phenomenon, the characteristic aspect of entomophtoromycosis. Outcome was favorable after treatment with itraconazole. DISCUSSION: Basidiobolomycosis is a deep mycosis rarely observed in children. Most reported cases have occurred in the tropics. The clinical presentation can simulate deep scleroderma or a tumoral disease. Treatment is currently based on imidazole derivatives which are particularly effective.

RESUMO

INTRODUCTION: The aim of this report is to describe an HIV-2 seropositive patient from Mali who had adult-T cell Leukaemia/Lymphoma associated with HTLV-I infection. CASE REPORT: The patient presented with erythroderma and foliate lymphocyte leukaemia. Skin biopsy showed an epidermotropic lymphoma. Tumoural cells expressed a mature T-cell phenotype CD4+/CD25+. High anti-HTLV-I titers and the evidence of monoclonal integration of HTLV-I provirus within circulating lymphoid cells led to the confirmation of HTLV-I as the causal agent in tumour cell transformation. HIV-2 serology was positive. DISCUSSION: Sub-Saharan Africa is a vast reservoir of HTLV-I virus with at least 5 million infected persons. Cases of adult-T cell Leukaemia/Lymphoma in Africans are exceptional. Lack of sufficient knowledge of the disease could partially explain this discrepancy. The main differential diagnosis in dermatology is primary T-cell lymphomas of the skin, particularly mycosis fungoides and Sézary syndrome.
