[Cerebral toxoplasmosis in the infectious diseases department of the CHU du Point G in people living with HIV]. / La toxoplasmose cerebrale dans le service de maladies infectieuses du CHU du Point G chez les personnes vivant avec le VIH.

Toxoplasmosis is defined as a cosmopolitan protozoan disease caused by an obligate intracellular coccidia, Toxoplasma gondii. The advent of HIV infection has made cerebral toxoplasmosis one of the most widespread neurological opportunistic infections. METHOD: We conducted a descriptive cross-sectional study with retrospective review of files of cerebral toxoplasmosis on HIV infected patients who had been hospitalized in the infectious diseases department of Point G University Hospital between January 1st, 2014 and September 30th, 2019. RESULTS: During the study period, the frequency of cerebral toxoplasmosis was 10.1% and in 46.4% of the patients, the diagnosis led to the discovery of HIV co-infection. The clinical features were characterized by fever, headaches, and motor deficit at 86.6%, 84.5% and 69.1% respectively. Roundel image on computed tomography was most represented and was found in 24.4% of patients. Anti-toxoplasma treatment based on trimethoprim /sulfamethoxazole (TMP/SMX) associated with folinic acid was initiated in 78 patients out of 90, but 19 patients had a contraindication or adverse effects to this combination and were treated with clindamycin. HAART was initiated in 31 patients out of 45 (68.9%) newly diagnosed. The overall prognosis was limited with a mortality rate of 42%. CONCLUSION: The prevalence of cerebral toxoplasmosis was high in our study, 10.1%. To reduce this prevalence, chemoprophylaxis should be initiated in all HIV-infected patients with a CD4 count below 200 cells/mm3.

INTRODUCTION: La toxoplasmose est une protozoose cosmopolite due à Toxoplasmagondii. Avec l'avènement du VIH, la toxoplasmose cérébrale est une des infections opportunistes neurologiques les plus répandues. MÉTHODE: Nous avons mené une étude transversaledescriptive à collecte rétrospective portant sur des cas de toxoplasmoses cérébrales sur terrain d'immunodépression aux VIH ayant séjourné en hospitalisation dans le service des maladies infectieuses du CHU de Point G du 1er janvier 2014 au 30 septembre 2019. RÉSULTATS: La prévalence de la toxoplasmose cérébrale était de 10,1%. Chez 46,4% des patients, le diagnostic de toxoplasmose cérébrale avait permis la découverte d'une coïnfection à VIH. Le tableau clinique était dominé par la fièvre, les céphalées et le déficit moteur soit respectivement 86,6%, 84,5% et 69,1%. L'image en cocarde à la tomodensitométrie a été retrouvée chez 24,4% des patients. Le traitement anti-toxoplasmique à base de triméthoprime/sulfaméthoxazole (TMP/ SMX) associée à l'acide folinique a été conduit chez 78 patients sur 90. Dix-neuf patients avaient une contre-indication ou des effets indésirables à l'association TMP/ SMX et ont été traités par la clindamycine. Le traitement ARV a été initié chez trente-un patients sur 45 nouvellement dépistés soit 68,9%. Le pronostic chez nos patients était réservé et marqué par une mortalité de 42%. CONCLUSION: La prévalence de la toxoplasmose cérébrale était élevée dans notre étude soit 10,1%. Pour diminuer cette prévalence, la chimio-prophylaxie doit être instaurée chez tous les patients infectés par le VIH et ayant un taux de CD4 inférieur à 200 cellules/mm3.

[Descriptive study of COVID-19 cases in the third Municipality of Bamako, from March 26 to August 27, 2020]. / Etude descriptive des cas de COVID-19 en Commune III de Bamako du 26 Mars au 27 Aout 2020.

INTRODUCTION: A public health emergency of international concern, COVID-19 is an acute respiratory disease responsible in eight months of approximately 843,158 deaths worldwide, including 29,425 deaths in Africa. The objective was to describe the COVID-19 cases in the health district of Commune III of Bamako. METHODS: This was a descriptive cross-sectional study of COVID-19 surveillance data from March 26 to August 27, 2020. Our variables were extracted from the surveillance database and analyzed on Epi-Info 7.2. Frequencies, rates and proportions were calculated. RESULTS: A positivity rate of 14.86% identified 126 confirmed cases out of an 848 notified suspect. The median age of confirmed cases was 34 years with a minimum of 8 months and a maximum of 93 years. The sex ratio was 2.7 males to females. Civil servants accounted for 32.54% of the positive cases. All the health subdistricts have recorded positive cases. The lethality was 7.94% affecting those over 65 years old. Among asymptomatic people 10.75% were confirmed positive for COVID-19. CONCLUSION: Our study suggests that young males were more likely to be infected with COVID-19. We recommend systematic screening of all contacts and involvement of the community in surveillance.

[Study of factors associated with maternal mortality by the audit method in the Segou region]. / Etude des facteurs lies aux deces maternels par la methode d'audit a l'hopital nianankoro fomba de Segou.

INTRODUCTION: Maternal mortality remains a public health problem in developing countries, including Mali. Among the factors associated with maternal mortality are sociodemographic and economicfactors, but also dysfunctions related to the health care system. It is in this context that this study was conducted in the gynecology and obstetrics department of the Nianankoro Fomba Hospital in Ségou to determine the factors associated with maternal deaths by the audit method in the Segouregion. METHOD: It was a cross-sectional, descriptive and retrospective study that was conducted from January 2014 to December 2015. The data were captured and analyzed on Epi Info version 2003. RESULTS: The analysisincluded 41 auditeddeaths out of 79 maternaldeathsreportedduring the period, amaternalmortality rate of 51.90%. Direct obstetric causes accounted for the majority (51.23%). Of these causes hemorrhagewas the main with 17.08% followed by eclampsia (14.63%). 31.71% of deathswerepreventable. The main riskfactorsidentifiedwere: delayed care, referral / evacuationdelay, diagnostic errors (hospitallevel), non-availability of blood. CONCLUSION: Continueddeath audits at the healthfacilitylevelcouldbe an approach to improving the quality of care and reducingmaternal and perinataldeaths.

INTRODUCTION: La mortalité maternelle demeure un problème de santé publique dans les pays en voie de développement dont le Mali. Parmi les facteurs associés à la mortalité maternelle on peut citer notamment les facteurs sociodémographiques et économiques, mais aussi les dysfonctionnements liés au système de soins. C'est dans ce cadre que cette étude été menée dans le service de gynéco-obstétrique de l'hôpital Nianankoro Fomba de Ségou pour déterminer les facteurs associés aux décès maternels par la méthode d'audit dans la région de Ségou. MÉTHODE: Il s'agissait d'une étude transversale, descriptive et rétrospective qui a étéréaliséede janvier 2014 à décembre 2015. Les données ont été saisies et analysées sur Epi Info version 2003. RÉSULTATS: L'analyse a porté sur 41 décèsaudités sur 79 décès maternels notifiés au cours de la période, soit un taux de décès maternels audités de 51,90%.Les causes obstétricales directes étaient majoritaires (51,23%).Parmi ces causes l'hémorragieétait la principale avec 17,08% suivie de l'éclampsie (14,63%). 31,71% des décès étaient évitables.Les principaux facteurs de risques identifiés ont été :le retard de prise en charge, le retard de référence / évacuation, les erreurs de diagnostic (niveau hôpital), la non disponibilité du sang. CONCLUSION: La poursuite des audits des décès au niveau des établissements de santé pourrait être une approche d'amélioration de la qualité des soins et de réduction des décès maternels et périnatals.

[Surgery wound infection at surgery "A" department of the University Hospital Point G]. / Infection du site operatoire dans le service de chirurgie « A ¼ du CHU du Point G.

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.

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.

Postpartum infections in a tropical environment: The experience of the infectious diseases department at Fann Teaching Hospital of Dakar (Senegal).

To describe the epidemiology, clinical characteristics, and outcomes of infections in postpartum women admitted to the infectious diseases department at Fann Teaching Hospital. This retrospective descriptive study examined the records of women admitted for infectious diseases within 42 days after childbirth during the five-year period (2007-2011). Data were collected from medical files and analyzed with Sphinx plus2 V5 software. In all, 54 women were admitted for infections during the postpartum period. Their mean age was 27.4 ± 6.2 years. Fifty women (93%) had had vaginal deliveries. The average interval from delivery to admission was 15.4 ± 11.0 days. Tuberculosis (14 cases), vaginitis (13 cases), and severe malaria (7 cases) were the most frequent infectious diseases. The average duration of hospitalization was 12.1 ± 9.0 days. The mortality rate was 30%, with the main causes of death tuberculosis (25 %) and severe pneumonia of unknown causes (25 %). Tropical diseases remain frequent during the postpartum period, with a high lethality rate, as this study shows. Early diagnosis during pregnancy and better follow-up after delivery should be the best ways of reducing morbidity and mortality from these infections.

[Post-circumcision Tetanus: Epidemiological, Clinical, Prognostic and Evolutionary Aspects of 16 Cases Collected at the Department of Infectious and Tropical Diseases in Fann Hospital (Dakar)]. / Tétanos postcirconcision : à propos de 16 cas colligés à la Clinique des maladies infectieuses du CHNU de Fann (Dakar).

This retrospective, descriptive study carried out in the Infectious Diseases Department of CHNU, Fann from 1st January 2012 to 3st December 2016 aimed to describe the epidemiological aspects and the course of post-circumcision tetanus and to formulate public health recommendations. During our study period, 16 cases of post-circumcision tetanus were collected out of a total of 452 patients with tetanus, equivalent to a rate of 3.5%. The median age was 8 years (3-40). None of the patients had a vaccination card. In 63% of cases, circumcision was performed at home, by a practitioner whose qualification was not documented in 63% of cases. All signs of tetanus were found with trismus (100%), dysphagia (63%) and paroxysms (88%). These were mostly Mollaret stage II forms in 14 cases, and grade 3 Dakar score in 7 cases. The median duration of hospitalization was 10 days [6-15]. Mechanical or infectious complications were noted in two cases, with a lethality rate of 13%. Post-circumcision tetanus is a reality in Senegal. Good community awareness, continuous training of staff and implementation of vaccination catch-up strategies for children of circumcised age should eradicate this form of tetanus.

Cette étude rétrospective descriptive, réalisée à la Clinique des maladies infectieuses du CHNU de Fann du 1er janvier 2012 au 31 décembre 2016 avait pour but de décrire les aspects épidémiologiques et évolutifs du tétanos postcirconcision et de formuler des recommandations en termes de prévention. Durant la période d'étude, 16 cas de tétanos postcirconcision ont été colligés sur un total de 452 patients atteints de tétanos, soit une fréquence hospitalière de 3,5 %. L'âge médian était de huit ans (3­40). Aucun des patients ne disposait de carnet de vaccination. Dans 63 % des cas, la circoncision a été effectuée à domicile, par un praticien dont la qualification n'a pas été documentée dans 63 % des cas. Tous les signes du tétanos ont été retrouvés avec le trismus (100 %), la dysphagie (63 %) et les paroxysmes (88 %). Il s'agissait surtout de formes de moyenne gravité classées au stade II de Mollaret dans 14 cas, et au score 3 de Dakar dans sept cas. La durée médiane d'hospitalisation était de dix jours [6­15]. Des complications mécaniques ou infectieuses ont été notées dans deux cas, avec une létalité de 13 %. Le tétanos postcirconcision est une réalité au Sénégal. Une bonne sensibilisation de la communauté, la formation continue du personnel et la mise en place de stratégies de rattrapage vaccinal des enfants en âge d'être circoncis devraient permettre d'éradiquer cette forme de tétanos.

[Malaria associated with bacterial infection in the department of infectious diseases at the National and University Hospital of Fann, Dakar]. / Paludisme grave et infections bacteriennes associees au service des maladies infectieuses du centre hospitalier National et Universitaire de Fann a Dakar.

OBJECTIVES: To describe severe malaria cases with bacterial infection. PATIENTS AND METHODS: We conducted a prospective, descriptive and analytical study over 8 months. RESULTS: 15 of the 86 severe malaria cases had bacterial infections: enteritis (7 cases), urinary tract infection (4 cases), meningitis (4 cases), pneumonia (cases), sepsis (1 case), and sinusitis (1 case). Convulsions, jaundice, abnormal bleeding, pulmonary edema were more frequent in patients with associated infections. The average number of leukocytes and CRP were significantly higher in patients with bacterial infection. The mean parasite density was higher in patients without bacterial infection (56,362/mm3 vs. 239,162.2 ± 3326/mm 3 ± 7175.3). Lethality was higher in patients with bacterial infection (20% versus 16.9%). CONCLUSION: Bacterial infections are common in severe malaria and may influence the prognosis.

OBJECTIFS: Décrire les cas de paludisme grave avec infection bactérienne associée. PATIENTS ET MÉTHODES: Etude prospective, descriptive et analytique sur 8 mois. RÉSULTATS: Parmi les 86 cas de paludisme grave, 15 avaient des infections bactériennes: Entérite (7 cas), Infections urinaires (4 cas), méningites (4 cas), pneumopathies (cas), septicémie (1 cas), sinusite (1 cas). Les convulsions, l'ictère, le saignement anormal, l'œdème pulmonaire étaient plus fréquents chez les patients présentant des infections associées. Le nombre de leucocytes moyen et la CRP était significativement plus élevé chez les patients avec infection bactérienne. La densité parasitaire moyenne était plus élevée chez les patients sans infection bactérienne (56362/mm3 ± 239162,2 Vs 3326/mm3 ±7175,3). La létalité était plus élevée chez les patients avec infection bactérienne (20% contre 16,9%). CONCLUSION: Les infections bactériennes ne sont pas rares au cours du paludisme grave et peuvent en influencer le pronostic.

[Evaluation of tolerance of zidovudine-lamivudine-nevirapine combination in HIV 1 patients in Fann Teaching Hospital in Dakar]. / Évaluation de la tolérance de l'association zidovudine-lamivudine-névirapine chez les patients VIH-1 au Centre hospitalier de Fann à Dakar.

We conducted a study to evaluate the tolerance of the zidovudine (AZT), lamivudine (3TC) and nevirapine (NVP) combination regimen in HIV-1 patients by a descriptive analytical retrospective study of all HIV-1 patients receiving AZT-3TC-NVP combination between 2008 and 2011. Seventy patients were included. Two thirds of the patients presented at least one side effect (44 cases). The digestive disorders (15 cases) and neuropsychiatric (14 cases) were the most frequent. Epigastralgia (20%), headaches (20%) and arthralgias (13%) were main side effects. A maculo-papular exanthema was noted in three cases. During the follow-up, five patients presented with anemia. No patient presented hepatic cytolysis due to NVP. All the patients followed for more than six months presented a side effect against 29.7% when the duration of treatment was equal to or less than 6 months (p=10(-5)). Most of the side effects due to the association AZT/3TC/NVP are minor. The evaluation of the clinical and biological tolerance must be maintained during all the follow-up.

[Current profile of cerebral toxoplasmosis in a hospital setting in Dakar]. / Profil actuel de la toxoplasmose cérébrale en milieu hospitalier à Dakar.

OBJECTIVE: To describe the current epidemiologic, clinical, diagnostic, and prognostic characteristics of cerebral toxoplasmosis in a hospital setting in Dakar. METHODS: This descriptive and analytic study examined the records of all HIV-positive patients with cerebral toxoplasmosis hospitalized at the infectious disease department at Fann (teaching) Hospital from January 2007 through December 2010. The diagnosis was based on clinical and computed tomography criteria completed by a therapeutic test with Cotrimoxazole. RESULTS: There were 26 cases of cerebral toxoplasmosis during the study period. The sex ratio (F/M) was 1.4. The mean age was 41.5 ± 11.2 years. The clinical signs were predominantly fever (88.5%), headache (77.5%), focal signs (64.5%), and disorders of consciousness (61.5%). Brain lesions were most often multiple (64.3%), with mass effects (54.1%) and peripheral edema (77.8%). Seven of the 26 patients died (lethality rate: 29.1%). Impaired consciousness (p = 0.023), high CD8 T-cell counts (p = 0.009), and anemia (p = 0.003) were significantly associated with a higher mortality rate. CONCLUSION: Cerebral toxoplasmosis remains a complication of AIDS in Dakar. Anemia, impaired consciousness, and high CD8(+) T cell counts were factors indicative of poor prognosis.

[Elimination of maternal and neonatal tetanus in Senegal: evolution of survey indicators of 2003-2009]. / Élimination du tétanos maternel et néonatal au Sénégal : évolution des indicateurs de surveillance de 2003 à 2009.

OBJECTIVES: This study aimed to estimate the evolution of the maternal and neonatal tetanus in Senegal from the tetanus vaccination coverage among pregnant women, the proportion of deliveries attended by trained medical personnel and the number of cases of tetanus declared by respective districts, helping to identify districts at high risk of neonatal tetanus (NNT). METHOD: Data analysis of the epidemiological surveillance realized from 2003 to 2009 in 65 districts of Senegal. Data were collected from the reports of vaccination usage and from the Statistical Directories of the National Health Information Services of the Ministry of Health & Prevention. A district is at high risk when the incidence of NNT is ≥1 case per 1 000 Live births (LB). RESULTS: There were 153 reported cases of NNT in Senegal between 2003 and 2009. National incidence decreased from 0.08 to 0.03 case per 1 000 LB (p = 0,0008). The vaccination coverage of the pregnant women by at least two doses of tetanus vaccine (VAT2+) increased from 66% in 2003 to 78% in 2009. The percentage of districts that had reached a vaccination coverage ≥80% was 20% in 2003 compared to 60% in 2009 (p = 0.009). The proportion of deliveries attended by qualified medical staff evolved from 53% in 2003 to 67% in 2009 (p = 0,02). By 2009, the incidence of NNT was less than 1 case per 1,000 LBs in all districts. CONCLUSION: Assessing the elimination of maternal and neonatal tetanus in Senegal shows that progress has been made from 2003 to 2009. This was made possible through the organization of vaccination campaigns for women of childbearing age and the improvements in the conditions of deliveries.

[Efficacy and tolerance of tenofovir-lamivudine-efavirenz combination in HIV-1 patients in Fann Teaching Hospital in Dakar]. / Efficacité et tolérance de l'association ténofovir-lamivudine-éfavirenz chez les patients VIH-1 à la clinique des maladies infectieuses du CHNU de Fann à Dakar.

We conducted a study to evaluate the efficacy and tolerance of the tenofovir (TDF), lamivudine (3TC) and efavirenz (EFV) combination regimen in HIV-1 patients by a descriptive analytical retrospective study of all HIV-1 patients receiving TDF-3TC-EFV combination between 2007 and 2011. Collected data was analysed using EpiInfo™ version 6.04. One hundred patients were included, with an average follow-up duration of 27 months and 19 days (± 21 months and 14 days).We observed an average increase in body weight of about 8 kg per annum, with an average rise in CD4 count of 100/mm(3) by the end of the second year. A reduction in viral load with 71% of patients in therapeutic success at 24 month of treatment was noted. Ninety-two patients presented with at least one side effect, mostly being Grade 1 or 2 (96.36%). Neurological (24 patients) and digestive (20 patients) complaints comprised the commonest reported side effects. Four patients had adverse effects severe enough to warrant a change in treatment regimen, principally due to renal insufficiency. Thirteen subjects died. Patients receiving TDF-3TC-EVF combination therapy need rigorous surveillance because this combination, although efficient, is not without significant adverse effects.

[Current profile of HIV-infected patients hospitalized in Dakar (Senegal)]. / Profil actuel des patients infectés par le VIH hospitalisés à Dakar (Sénégal).

Ten years after the introduction of the Senegalese Antiretroviral Drug Access Initiative in 1998, we conducted a retrospective study of the epidemiological and clinical profiles and outcome of HIV-infected patients hospitalized in the Infectious Diseases Clinic of Fann Teaching Hospital in Dakar between 2007 and 2008. During these 2 years, 527 HIV-positive patients were included. The average age of the patients was 41 ± 10 years, and the sex-ratio (F/M) was 1.1; 56% of patients were married. The average interval before admission was 40 ± 57 days. Fever (83%), loss of weight (83%) and cough (54%) were the principal symptoms. Tuberculosis (40.9%) and gastrointestinal candidiasis (38.9%) were the commonest opportunistic infections. Most patients were diagnosed at the AIDS stage (88%) and the CD4+ T lymphocyte count was ≤ 200/mm3 in 86% of cases. Hospital fatality was 44% (231/527). Tuberculosis (36%), bacterial pneumonia (18%) and encephalitis (12%) were the most frequent causes of death. Despite the availability of and free access to antiretroviral drugs in Senegal, the mortality associated with HIV infection remains very high due to late diagnosis. The population must be educated to boost early screening and care.

[Human rabies: diagnostic pitfalls]. / La rage humaine, un diagnostic parfois difficile.

The purpose of this report is to describe two cases of human rabies in Senegal that illustrate possible diagnostic and therapeutic pitfalls even in an endemic area. Although outcome is almost always fatal and interhuman transmission is uncommon, prompt diagnosis of rabies is important since delay increases the risk of exposure to the virus for the entourage.

The effectiveness of Mesocyclops longisetus (Copepoda) for the control of container-inhabiting mosquitoes in residential environments.

The cyclopoid crustacean Mesocyclops longisetus was evaluated for its predatory potential to reduce container-inhabiting mosquitoes in 5 suburban Florida backyards. Aedes albopictus, Ae. triseriatus, and Culex quinquefasciatus were the predominant species collected from containers. At an initial inoculation rate of approximately 120 copepods per container, M. longisetus populations eliminated resident mosquito larvae for a minimum of 14 wk in 30-liter plastic buckets and up to 29 wk in 0.4-liter ceramic flowerpots and 0.3-liter glass jars depending on species. Copepod populations generally peaked 13 wk after introduction (August) in ceramic flowerpots and glass jars and about 1 month later in tires, plastic buckets, and plastic flowerpots. At the time of peak abundance, average predator numbers ranged between 900 (glass jar) to >3000 (30-liter bucket) individuals per container. Although all mosquito species were eliminated from all containers sometime during the 35-wk study, M. longisetus appeared to preferably prey on Aedes larvae compared with Culex. Operationally, the use of M. longisetus as a tool for control of container-inhabiting mosquitoes in urban/suburban settings proved to be relatively inexpensive, required little labor for colony maintenance, was easily transported, and easily applied.

CONTEXT: The long term treatment of VIH/SIDA puts down majors risks among which the happening of virological failure or resistance to the anti-retroviral treatment at the patient. OBJECTIVE: To study the cases of resistance to antiretroviral to a cohort of 70 patients of the social hygiene of Dakar. METHOD: This is a retrospective study of the medical records of 70 patients followed in the social hygiene of Dakar during 24 mouths. Data were gathered with the help of form having following variables: The period of meadow inclusion; The period of inclusion; The period of rebound virological; The rate of CD4 count; The viral load and weight of patients. RESULTS: Average of age in inclusion is of 47.5 years with a sex ratio of the women HIV 1 was dominant. Two cases of virological failure were found or (2.8%). The patient 1 was the stade II of the classification of the with as therapeutic class 2INTI + 2 INNTI. It was in stage asymptomatic with as therapeutic protocol DDI + 3TC + NVP. The patient 2 was at the stade III of the whom that is to say at the stade in AIDS with as therapeutic class: 2INTI + 1IP with the protocol of treatment DDI + 3TC +IND. CONCLUSION: The virological failure to the newly infected persons noticed more and more in the world poses a problem of public health because it constitutes a threat for the success of the programs of treatment of the HIV/AIDS.

[Knowledge, behaviors and practices among ironworkers about tetanus in Senegal]. / Connaissances, attitudes et pratiques a propos du tétanos chez les ferronniers a Dakar, Sénégal.

Tetanus is still a major health problem in Sénégal. In order to understand some of these reasons, we conducted a study. The aim of this study is to assess ironworkers' knowledge, behaviors and practices about tetanus. This knowledge, behaviors and practices survey was carried out in ironworks of two neighborhoods of Dakar from April 5 to May 10, 2008. 41 ironworks were identified and 32 agreed to participate in the study. In this ironworks, 120 ironworkers were interviewed. Their average age was 29 years +/- 15, education in French schools was low and 78.3% of them had a source of information. Despite some inaccuracies, most ironworkers were aware of tetanus (97.5%), severity (93.3%), causes (89.2%). However 35% did not evaluate the risk of tetanus and almost all the ironworkers or 96.7% had no preventive measures after injury. Moreover, no ironworker was fully immunized against tetanus. In some occupations at risk, awareness of tetanus should be increased by all available channels and methods emphasizing the importance of prevention.

[Parasitic and fungal neuroinfections at the Infectious Diseases Clinic in Fann Teaching Hospital in Dakar]. / Neuro-infections parasitaires et mycosiques a la clinique des maladies infectieuses du Chu de Dakar.

OBJECTIVES: This retrospective study was carried out to describe the epidemiological, clinical and aetiological profile of parasitic and fungal neuroinfections at the Infectious Diseases Clinic in Fann Teaching Hospital in Dakar. PATIENTS AND METHODS: Data were collected for analysis from patients files recorded from January 1, 2001 to December 31, 2003. RESULTS: We found 126 cases of parasitic and fungal neuroinfections, representing 62% of the total of neuroinfections cases (126/203) and 27% of cerebro-meningeal diseases encountered at the clinic during the study period (126/470). Sex ratio M/F was 1.7 and the mean age of patients was 32 years +/- 14.4. Thirty seven patients (30%) were HIV seropositive. Aetiologies were represented by cerebral malaria (85 cases), neuromeningeal cryptococcosis (37 cases) and toxoplasmosis (4 cases). The overall case fatality rate was 38% (48 deaths/126). The fatality rate varied according to aetiologies: 27% in cerebral malaria, and 59.5% in neuromeningeal cryptococcosis that was found mainly among HIV positive patients (34 cases/37). CONCLUSION: These results give evidence of the frequency and the gravity of the adult's cerebral malaria in Dakar, but also the growing place of the neuromeningeal cryptococcosis in the neuromeningeal opportunist pathology of HIV positive patients.

[Tolerance study of a triple first-line antiretroviral combination zidovudine, lamivudine and efavirenz in Dakar, Senegal]. / Etude de la tolérance d'une trithérapie antirétro- virale de première intention associant zidovudine, lamivudine et efavirenz à Dakar, Sénégal.

This study aimed at describing the side-effects reported in patients infected with HIV-1 treated initially by the association zidovudine, lamivudine and efavirenz between 2002 and 2007 in the Regional Centre of Clinical Research and Training in Dakar as part of the cohort of the Senegalese Initiative Access to Antiretroviral. Adverse effects were entered and analysed using the software Epi Info version 6.04. The average age of the patients was 38 years old. During the follow-up (average = 741 days), adverse effects were reported 75 times and 39 patients were concerned. The most frequent type of side-effects was neuropsychiatric (47%), digestive (20%) and dermatological (16%). They were severe in 13% of cases and severe anaemia was noted in eight cases. These required a change of therapy in 19%, mainly for severe anaemia (15%). The association zidovudine, lamivudine and efavirenz doesn't seem to induce severe side-effects. Nevertheless, considering the frequency of neuropsychiatric side-effects and severity of hematological side-effects, attention should be paid to neuropsychiatric and blood examination of patients undergoing this combination antiretroviral therapy.

[The place of malaria in an infectious disease department in Dakar, Senegal]. / Place du paludisme dans un service de pathologie infectieuse a Dakar (Sénégal).

The aims of this study were to determine the place of malaria at the Infectious Disease Clinic in Dakar, Senegal, to identify diseases associated with malaria, and to assess malaria mortality with or without co-morbidity. The files of all patients hospitalized from 2001 to 2003 in whom at least one test for malaria (thick films/spears) was performed to detect malaria parasites were reviewed. Malaria was diagnosed in patients presenting fever and positive thick films demonstrating asexual blood stages of Plasmodium. Data were collected from hospital charts. A total of 416 patients presented malaria (prevalence rate, 25.9%). The male-to-female sex ratio was 1:7 and mean age was 33 +/- 18 years. Of the 416 patients diagnosed with malaria, 273 (65.6%) presented severe forms. The overall mortality rate of malaria with or without co-morbidity was 25.7% (107/416). There was not a statistically significant difference between mortality due to isolated malaria and malaria associated with tuberculosis (23.4% versus 18.5%) (p = 0.7) or tetanus (23.4% versus 17.6%) (p = 0.34). Conversely mortality of malaria in HIV-positive patients was higher (58% versus 19%) (p = 10(-6)). Thus, malaria is of major concern in our department.

[Neuromeningeal cryptococcosis in patients apparently non-immunodeficient: report of 3 cases in Dakar, Senegal]. / Cryptococcose neuroméningée chez des patients apparemment non-immunodéprimes: à spropos de 3 cas à Dakar, Sénégal.

Cryptococcal infection is common in immunocompromised patients. Its occurrence in immuno-competent patients is rare. We report here 3 cases of neuromeningeal cryptococcosis in patients without any immunosuppressive documented factors. They were respectively 25, 36 and 50 years old presenting clinical signs of chronic meningo-encephalitis. The HIV test was negative for all of them and the CD4 counts were normal. One patient died on the seventh day of the treatment with amphotericin B; the second was discharged on parents' request, while the third patient improved with intravenous fluconazole. This study suggests that when facing a sub-acute or chronic meningitis, an investigation for cryptococcal infection is recommended as before AIDS epidemic.
