Adult groin hernia surgery in sub-Saharan Africa: a 20-year systematic review and meta-analysis.

PURPOSE: To realize a systematic review to evaluate groin hernia surgery for adults in sub-Saharan Africa. METHODS: We conducted a systematic review and meta-analysis, the primary objective of which was to determine the surgical techniques used for unilateral groin hernia surgery in sub-Saharan Africa. Studies published in the last 20 years were considered. A meta-analysis estimated the pooled prevalence with 95% confidence interval (CI) of mortality, chronic pain and recurrence. A subgroup analysis compared the rate of complications between complicated or uncomplicated hernia. RESULTS: We included 113 articles. The most used technique was Bassini in 40.1%, followed by Lichtenstein in 29.9% and Shouldice in 12.6%. The overall mortality rate was 0.6% (95% CI 0.4-0.9). The pooled recurrence rate was 1.4% (95% CI 1.05-1.9). The pooled rate of chronic pain was 2.7% (95% CI 1.9-3.7). We found that mortality rate for complicated hernias (6.4%) was higher compared to uncomplicated hernias (0.2%). This difference was statistically significant [p ≤ 0.001; OR = 47.7; 95 CI (27.2-83.47)]. CONCLUSION: This review showed that pure tissue repairs are the most used techniques with Bassini and Shouldice as leading procedures. The post-operative rates of recurrence and chronic pain are low. However, there is a high heterogeneity between studies than can underestimate these pooled prevalences. The consultation at complication stage remains frequent and associated with a higher mortality. Futures studies should focus on improving the quality of studies in terms of design and follow-up to increase the degree of evidence.

[Healthcare associated infections in the neurosurgical department of Gabriel Touré teaching Hospital in Bamako]. / Les infections associees aux soins dans le service de neurochirurgie du CHU Gabriel Toure a Bamako.

INTRODUCTION: Healthcare-associated infections or nosocomial infections are a public health problem due to their frequency, severity and economic impact. They cause an increase of the morbidity, the mortality, the hospital stay and the expenses of taking care of the patients. According to the WHO, 7.1 million people are affected each year, of which about 100,000 die. AIM OF STUDY: The aim of this study was to determine the frequency of healthcare-associated infections in the Neurosurgery Department of Gabriel Touré University teaching Hospital and to identify the risk factors associated with these infections. MATERIAL AND METHODS: This was an epidemiological, descriptive, analytic, cross-sectional and prospective study lasting 6 months from May 29 to November 30, 2016. The study focused on patients who stayed more than 48 hours in the Neurosurgical department Gabriel Touré teaching hospital. The collected data focused on the clinical and biological characteristics of the patients during their hospitalization. The maximum size of the sample was 200 patients. A sample was taken for each type of infection. The criteria used for the diagnosis of Healthcare-associated infections were those of the CDC (Center for Disease Control) and the realization of a thick drop in our context. The chi-square test was used for the comparison of qualitative variables and Kruskal Wallis and Anova for quantitative variables. The materiality threshold has been set to a value of p less than 0.05. RESULTS: At the end of our study, we had 34 infected patients out of 200, a rate of 17%. The significant risk factors found in our study were: high age (p = 0.04), ASA class (p = 0.002), pre-surgical shaving (p = 0.02), long duration surgical intervention (p = 0.002) and long hospital stay (p = 0.004). The types of infections associated with the care found were: urinary in 18 (53%) cases, respiratory in 9 (26%) cases, operative site in 6 (18%) cases and 1 (3%) cases of bacteremia. The bacterial spectrum of these infections was dominated by Negative Gram Bacilli, among which Escherichia coli in 11 (32.3%) cases. The clinical course of patients treated for these infections was marked by healing in 31 (91.2%) cases, complications in 2 (5.9%) cases, and death in 1 (2.9%) case. CONCLUSION: The prevalence of Healthcare-associated infections in our department remains high compared to that found in developed countries. This study allowed us to identify the main risk factors associated with these infections. A stricter adherence to the rules of hygiene and prevention of Healthcare-associated infections is needed to reduce this rate.

INTRODUCTION: Les infections associées aux soins (IAS) ou infections nosocomiales constituent un problème de santé publique par leur fréquence, leur gravité et leur retentissement économique. Elles causent une augmentation de la morbidité, la mortalité, le séjour hospitalier et les frais de prise en charge des malades.Selon l'OMS, 7,1 millions de personnes seraient affectées par les IAS chaque année parmi lesquelles environ 100000 meurent de suites de ces ISA. BUT: Le but de cette étude était de déterminer la fréquence des infections associées aux soins dans le service de Neurochirurgie du CHU Gabriel Touré et d'identifier les facteurs de risque associés à ces infections. MATÉRIEL ET MÉTHODES: Il s'agissait d'une étude prospective d'une durée de 6 mois allant du 29 Mai au 30 Novembre 2016. L'étude a porté sur les patients ayant séjourné plus de 48 heures dans le service de Neurochirurgie du CHU Gabriel Touré.Les données collectées ont porté sur les caractéristiques cliniques et biologiques des patients au cours de leur hospitalisation.La taille maximum de l'échantillon a été de 200 malades. Un prélèvement a été fait pour chaque type d'infection.Les critères utilisés pour le diagnostic de l'IAS étaient ceux du CDC (Center for Disease Control) d'Atlanta ainsi que la réalisation d'une goutte épaisse dans notre contexte.Le test de khi2 a été utilisé pour la comparaison des variables qualitatives et Kruskal Wallis et Anova pour les variables quantitatives. Le seuil de signification a été fixé à une valeur de p inférieure à 0,05. RÉSULTATS: Au terme de notre étude nous avons eu 34 patients infectés sur 200, soit un taux de 17%. Les différents facteurs de risque significatifs retrouvés dans notre étude ont été : l'âge élevé (p=0,04), la classe ASA (p=0,002), le rasage pré-chirurgical (p=0,02), la longue durée de l'intervention chirurgicale (p=0,002) ainsi que la longue durée d'hospitalisation (p=0,004). Les types d'infections associées aux soins retrouvés ont été : urinaires dans 18 (53 %) cas, respiratoires dans 9 (26%) cas, site opératoire dans 6 (18%) cas et 1 (3%) cas de bactériémie. Le spectre bactérien de ces infections était dominé par les Bacilles Gram Négatifs parmi lesquels l'Escherichia coli dans 11 (32,3%) cas.L'évolution clinique des patients traités pour ces infections a été marquée par la guérison dans 31 (91,2%) cas, les complications dans 2 (5,9%) cas et le décès dans 1(2,9%) cas. CONCLUSION: La prévalence des infections associées aux soins dans notre service reste élevée par rapport à celle retrouvée dans les pays développés. Cette étude nous a permis d'identifier les principaux facteurs de risque associés à ces infections. Une observance plus stricte des règles d'hygiène et de prévention des IAS s'impose pour faire baisser ce taux.

[Epidemiology and prognosis of childhood cancers at Gabriel-Touré Teaching Hospital (Bamako, Mali)]. / Épidémiologie et pronostic des cancers pédiatriques au CHU Gabriel-Touré de Bamako (Mali).

UNLABELLED: Cancer today is being treated as a public health problem in Africa, as in developed countries. OBJECTIVE: The aim of this retrospective study was to evaluate the epidemiology and outcome of children treated in the Pediatric Oncology Unit of Gabriel Touré Teaching Hospital in Bamako (Mali), six years after it opened. METHODS: Retrospective study of the files of all children aged 15 and younger diagnosed with cancer and treated by chemotherapy between January 1, 2005, and December 31, 2010. RESULTS: The study included 690 children. Their mean age was 24 months. The time from observation of first symptoms to consultation was less than 3 months in 200 cases (29%), from 3 to 10 months in 256 (37.1%), and more than 10 months in 234 (33.9%). The five most common childhood cancers were malignant non-Hodgkin's lymphoma (NHL) (n=231, 33.5%), retinoblastoma (n=170, 24.6%), nephroblastoma (n=102, 14.8%), acute lymphoblastic leukemia (n=54, 7%), and Hodgkin's disease (n=34, 4%). Six years after the unit opened and after a mean follow-up of 3 years, we recorded 272 deaths (39.4%); at least 238 children are still alive (34.5%), with 180 cases (26.1%) lost to follow-up. CONCLUSION: Childhood cancer survival is still low in Mali, and the rate of loss to follow-up quite high.

Acute sigmoid volvulus: results of surgical treatment in the teaching hospitals of Bamako.

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.

Hodgkin lymphoma at the paediatric oncology unit of gabriel touré teaching hospital, bamako, mali: 5-year experience.

Introduction. The aim of this retrospective, unicentric study over 5 years is to describe the epidemiologic, pathologic, clinic and therapeutic aspects of children treated for Hodgkin lymphoma in our paediatric oncology unit. Patients and Methods. From January 2005 to December 2009, all children under 18 years of age, with Hodgkin lymphoma were included in this study. The treatment protocol was the GFAOP (Groupe Franco-Africain d'Oncologie Pédiatrique) Hodgkin lymphoma treatment protocol. Results. During the study period, 217 cancer cases were diagnosed in our centre. Of these cases, 7 were Hodgkin Lymphoma (LH) (0.04%). The mean age was 11.7 years. The sex-ratio was 6/1. 4% (5/7) of patients were stage IIB and 28.6% (2/7) stage IIIB of Ann-Arbor classification. There were 3 cases (42.8%) of sclero-nodular subtype, 2 cases (28.6%) of lymphocyte-rich classical HL subtype, 1 case (14.3%) of mixed cellularity and 1 case (14.3%) of lymphocyte depleted subtype. With a median followup of 37 months, 5 patients (71.4%) are alive, and 2 patients (28.6%) died. Conclusion. Broader multicentric studies are needed for more accurate data on this malignancy.
