[Epidemiological and evolutionary profile of tuberculosis under the influence og HIV]. / Profil épidémiologique et évolutif de la tuberculose sous l'influence de l'infection par le VIH dans un centre de prise en charge ambulatoire au Gabon.

INTRODUCTION: We conducted this study to understand the impact of HIV infection on the epidemiology of tuberculosis (TB) in an outpatient care center. PATIENTS AND METHODS: This is a retrospective and comparative study between subjects infected or not infected with HIV, using TB case notification data registered from October 2017 to September 2019 in the intermediate care facility (CDT) of the University Hospital of Libreville. Comparisons were made by bivariate analysis; proportions were compared using the Chi2 or the Fisher Exact test. Variables of significant interest were included in a binary logistic regression model for multivariate analysis. RESULTS: Prevalence of HIV infection was 30.4%. Average age was 35.2 years with extremes at 15 and 83 years. In the results of the multivariate analysis, female patients were more frequently infected with HIV (p=0.002; OR=1.960, 95% CI [1.275 - 3.015]) and HIV infection was associated with a reduction in the proportion of PTB (+) (p=0.001; OR=0.483, 95% CI [0.311 - 0.752]). HIV infection was also associated with an increased proportion of new cases (P=0.007; OR=2.987, 95% CI [1.353 - 6.597]), EPT (p<0.001; OR=1.084, 95% CI [1.054 - 1.131] and an unfavorable therapeutic outcome (p=0.016; OR=2.744, 95% CI [1.208 - 6.233]). CONCLUSION: TB/HIV co-infection remains high. It continues to negatively impact outpatient management of TB.

Anémie chez les donneurs de sang volontaires après vérification de l'hémoglobine pré-don au Centre de Transfusion Sanguine de Libreville / Anemia in voluntary blood donors after verification of pre-donation hemoglobin at the Libreville Blood Transfusion Center

Introduction : La nécessité de disposer de produits sanguins labiles (PSL) de qualité est un impératif de la transfusion sanguine. Le don de sang n'est pas sans risque pour le donneur. Ce qui soulève la question de la perte de fer par spoliation sanguine. Ce constat a conduit à la réalisation de cette étude dans le but de rechercher l'anémie chez le donneur de sang volontaire jugé apte après évaluation de l'hémoglobine pré-don et d'en déterminer la cause. Patients et méthodes : Il s'agissait d'une étude transversale prospective réalisée au Centre National de Transfusion Sanguine (CNTS) de Libreville. La population d'étude était constituée de donneurs de sang, nouveaux ou anciens, volontaires en bonne santé chez qui les examens suivant ont été réalisés pour le diagnostic de l'anémie et celui de la carence en fer tout en excluant d'autre étiologies: l'hémogramme, le dosage de la Protéine C Réactive (CRP), le fer sérique, la ferritine, l'hepcidine et le test de diagnostic du paludisme (TDR).Résultats : Sur l'ensemble des deux cent quinze volontaires inclus, trente - quatre (15,8%) présentaient une anémie parmi lesquels douze femmes et vingt- deux hommes d'un âge moyen de 32,8 ±8,0. Le nombre de dons effectués était corrélé à la survenue de l'anémie selon le genre et l'âge du donneur. Il en a été de même pour les valeurs de la ferritine, du fer sérique.Conclusion : Le nombre important d'anémie est lié à un seuil bas de l'hémoglobine pré-don. Le caractère microcytaire hypochrome de l'anémie laisse supposer une origine ferriprive.

Introduction: The need to have quality labile blood products (LBP) is an imperative of blood transfusion. Blood donation is not without risk for the donor. This raises the question of the loss of iron by blood spoliation. This finding led to the realization of this study with the aim of looking for anemia in voluntary blood donors deemed suitable after evaluation of the pre-donation hemoglobin and to determine the cause.Patients and methods: This was a prospective cross-sectional study carried out at the National Blood Transfusion Center (CNTS) in Libreville. The study population consisted of blood donors, new or old, healthy volunteers in whom the following examinations were carried out for the diagnosis of anemia and that of iron deficiency while excluding other etiologies: blood count, C-Reactive Protein (CRP), serum iron, ferritin, hepcidin and malaria diagnostic test (RDT). Results: Of the two hundred and fifteen volunteers included, thirty-four (15.8%) presented anemia, including twelve women and twenty-two men with an average age of 32.8 ±8.0. The number of donations made was correlated with the occurrence of anemia according to the sex and age of the donor. It was the same for the values of ferritin, serum iron. Conclusion: The large number of anemia is linked to a low threshold of pre-donation hemoglobin. The hypochromic microcytic character of the anemia suggests an iron deficiency origin.

Profil épidémio-clinique, fonctionnel et de sensibilisation aux allergènes chez les asthmatiques suivis en consultation en milieu Africain à Libreville, Gabon / Epidemiological-clinical, functional profile and sensitization to allergens in asthmatics followed in consultation in an African environment in Libreville, Gabon

Introduction : La prévalence de l'asthme au niveau national est inconnue. L'objectif était de déterminer la prévalence hospitalière de l'asthme et la sensibilisation aux pneumallergènes standards.Patients et Méthodes : Il s'agit d'une étude transversale, rétrospective qui a consisté en l'analyse descriptive de 164 dossiers de patients asthmatiques reçus pour consultation au CHU de Libreville sur une période d'activité de 36 mois. La mesure du VEMS pré et post-bronchodilatateur ainsi que les prick-tests ont été réalisés. Les extraits standardisés suivants étaient testés : Dermatophagoïdes pteronyssinus et farinae, les phanères (chien et chat), les plantes vertes (Cynodon dactylon) et les moisissures (Alternaria sp). Résultats : Des 2798 patients reçus en consultation de pneumologie, 164 l'étaient pour un asthme soit une fréquence 5,8%. Parmi les 164 patients asthmatiques 59,8%(n=98) étaient des femmes avec un sex-ratio à 0,67. La moyenne d'âge de la population d'étude était de 31±18,1 ans, des extrêmes de 5 et 81 ans. Plus de la moitié des patients résidait en milieu urbain (59,7%), et était sans revenu (50,7%). L'asthme était associé à la rhinite allergique dans 72,6%. Seuls 45 patients avaient réalisé les prick tests parmi lesquels la sensibilisation aux acariens (n=37/45 ; 82,2%) était fréquente et dominée par Dermatophagoïdes pteronyssinus (n=32/37 ; 86,5%). La sensibilisation à Blomia tropicalis était de 73,0% (n=27/37). La sensibilisation aux phanères d'animaux (chiens et chats) était observée chez 9 patients (n=9/45 ; 20,0%). Aucune sensibilisation à l'Alténaria sp n'a été relevée. Le déficit ventilatoire obstructif proximal et distal a été observé dans 45,8% des cas (n=60/131).Conclusion : La prévalence de l'asthme est relativement élevé dans notre contexte d'exercice. Le taux sensibilisation révélé est le témoin d'une forte pression allergénique exercée par l'environnement domestique

Introduction: The national prevalence of asthma is unknown. The objective was to determine the hospital prevalence of asthma and sensitization to standard airborne allergens. Patients and Methods: This is a cross-sectional, retrospective study which consisted of the descriptive analysis of 164 records of asthmatic patients received for consultation at the University Hospital of Libreville over a period of activity of 36 months. Measurement of pre- and post-bronchodilator FEV1 as well as prick-tests were performed. The following standardized extracts were tested: Dermatophagoides pteronyssinus and farinae, skin appendages (dog and cat), green plants (Cynodon dactylon) and molds (Alternaria sp).Results: Of the 2798 patients seen in a pulmonology consultation, 164 were for asthma, i.e. a frequency of 5.8%. Among the 164 asthmatic patients 59.8% (n=98) were women with a sex ratio of 0.67. The average age of the study population was 31 ± 18.1 years, extremes of 5 and 81 years. More than half of the patients lived in urban areas (59.7%), and had no income (50.7%). Asthma was associated with allergic rhinitis in 72.6%. Only 45 patients had performed prick tests,among which sensitization to house dust mites (n=37/45; 82.2%) was frequent and dominated by Dermatophagoides pteronyssinus (n=32/37; 86.5%). Sensitization to Blomia tropicalis was 73.0% (n=27/37). Sensitization to animal dander (dogs and cats) was observed in 9 patients (n=9/45; 20.0%). No sensitization to Altenaria sp was noted. Proximal and distal obstructive ventilatory deficit was observed in 46.5% of cases (n=60/130).Conclusion: The prevalence of asthma is relatively high in our exercise context. The sensitization rate revealed is the witness of a strong allergenic pressure exerted by the domestic environment.

Malaria after chemotherapy for hematological malignancies.

The treatment of cancer, whether a solid tumor or a malignant hemopathy, is accompanied by bouts of infection, the severity and prognosis of which are often correlated to the patient's immune status. In Gabon, where the transmission of Plasmodium falciparum malaria is perennial, the prevalence - around 36% in Libreville - increases in older children and adults. Few authors have described the involvement of this parasite during fever after chemotherapy for hematological malignancies. This work reports three cases of malaria including two severe and one with neutropenia occurring in patients treated for hematological neoplasms.

Anticoagulant-induced pseudothrombocytopenia after a plasmodium falciparum infection in a five-year-old child.

Pseudothrombocytopenia or artefactual thrombocytopenia is an abnormally low number of platelets due to their agglutination in a sample tube, with no ex vivo clinical translation. It occurs in ethylene diamine tetraacetic (EDTA) test tubes. Non-EDTA anticoagulants, such as citrate, fluoride oxalate, and heparin lithium, may be responsible for it, alone or in combination. It can occur in patients with autoimmune diseases, neoplasia, atherosclerosis, liver disease, or infections. We report the case of a 5-year-old child, who after falciparum malaria showed persistent thrombocytopenia. Further exploration has led to the conclusion of pseudothrombocytopenia due to three anticoagulants: EDTA, citrate, and fluoride oxalate.

Pregnancy in autoimmune diseases in the sub-Saharan zone: the experience of the University Hospital of Libreville Department of Internal Medicine.

Autoimmune diseases are a group of heterogeneous conditions responsible for polymorphic clinical and biological manifestations. Because pregnancy activates them and promotes gestational complications, it is difficult for women with these diseases. Pregnancy and autoimmune diseases have rarely been studied in sub-Saharan Africa. We report the experience of the Internal Medicine Department of the University Hospital of Libreville. Conducted retrospectively for 2008 through 2011, and prospectively from 2012 through August 31, 2018, this descriptive and analytical study examined the records at the Department of Internal Medicine of the University Hospital Center of Libreville of women with a known autoimmune disease, receiving regular care there, and who became pregnant after the diagnosis. During pregnancy, women were monitored and manÂged simultaneously in the departments of obstetrics and internal medicine. Data considered for this study were demographic data (Âge, sex, social status), type of autoimmune disease, including the diagnosis, the therapies used, extent of disease control, and time from diagnosis to each pregnancy. Obstetric data include the number of fetuses, obstetric complications, gestational Âge at and route of delivery, fetal sex, and Apgar score to 5 minutes (normal ≥ 7). Women had the following autoimmune diseases : systemic lupus erythematosus (SLE) (n = 16), Sjögren's disease (n = 3), inflammatory myopathy (n = 2), rheumatoid arthritis (n = 1), primary antiphospholipid syndrome (APS) (n = 1), and Still disease (n = 1).The overall averÂge Âge at diagnosis was 26.6 years (range : 13-40). The 24 women had 32 pregnancies. The mean interval from diagnosis to first pregnancy was 3.3 years, to the second pregnancy also 3.3 years (n = 6), and to the third (n = 2), 5 years. Disease was controlled for at least 2 years (n = 23) except for one woman with primary APS. Therapeutically, corticosteroids were used alone (n = 2) or combined with other immunomodulatory therapies (n = 32). Gestational complications included spontaneous abortions in the first trimester (n =2), in utero deaths (n = 2), perinatal death on day 12 (n = 1), and eclampsia (n = 2), one of which was complicated by a pulmonary embolism in the first pregnancy. The mean gestational Âge at delivery was 37 weeks. Intrauterine growth restriction affected 11 fetuses, and preterm delivery 18. There were 11 cesarean deliveries and 16 vaginal. Mean birth weight was 2353.3 grams, Apgar was ≥ 7 for all neonates except in one case of dermatomyositis complicating a neonatal death. The sex ratio was 13 male infants per 17 females. Women with optimal disease control can become pregnant and have positive pregnancy outcomes. This possibility has been little explored in sub-Saharan Africa; mystical-religious notions of conceptions persist and can prevent women from attempting to become prégnant . This experience with a short series of viable fetuses of women with autoimmune diseases is therefore encouraging and deserves to be continued.

[About a Case of Febrile Gastroenteritis Due to Strongyloidiasis in a Gabonese Patient Treated for Lupus]. / A propos d'un cas de gastro-entérite fébrile due à une anguillulose chez une patiente gabonaise traitée pour un lupus.

Srongyloidiasis can sometimes be a source of diagnostic wandering in a patient with an autoimmune disease living in a tropical environment, despite systematic deworming with albendazole (400 mg/day/3 days), prior to the starting of a corticotherapy. We report an observation of a febrile gastroenteritis complicated by signs of intra and extracellular dehydration, in a 37-year-old lupus patient, including duodenal biopsies, and stool parasitology, which led to the diagnosis of strongyloidiasis effectively treated by ivermectin per os (two doses) of 200 micrograms/kg, once every 2 weeks apart), following failure of a first 5-days course of albendazole (400 mg/day).

L'anguillulose peut parfois être source d'errance diagnostique chez un patient porteur d'une maladie auto-immune vivant en milieu tropical, et ce malgré un déparasitage systématique par l'albendazole (40 mg/jour / 3 jours), avant la mise en route d'une corticothérapie. Nous rapportons une observation de gastroentérite fébrile, compliquée de signes de déshydratation intra et extracellulaire, chez une patiente lupique de 37 ans, dont les biopsies duodénales, et la parasitologie des selles ont conduit au diagnostic d'anguillulose traitée efficacement par ivermectine per os (2 doses de 200 microgrammes/kg, en prise unique à 2 semaines d'intervalle l'une de l'autre). Ce traitement faisait suite à l'échec d'un premier traitement par 5 jours d'albendazole (400 mg/jour).

Myeloblasts and atypical bone marrow: Fortuitous discovery of the filiarial nematode loa loa in the bone marrow during a work-up for prolymphocytic T-cell leukemia.

Loiasis is a chronic cutaneous disease caused by a filarial nematode for whom humans are the only definitive host: Loa loa, an African eyeworm transmitted by Chrysops flies. The parasite is seen on blood smears, in the skin, or during its ocular migration, but rarely on a bone marrow smear. We report the case of a 57-year-old Gabonese woman whose bone marrow aspiration during a work-up for T-cell leukemia fortuitously found Loa loa filariae.

[Behavior and attitudes towards smoking among student midwives in Libreville]. / Comportements et attitudes des élèves sages-femmes de Libreville vis-à-vis du tabagisme.

BACKGROUND: The midwife, in taking on a public health role, is one of the most important resources for the prevention of smoking and in helping smoking cessation among women of childbearing age thanks to their numerous contacts with pregnant women. With this in mind, we conducted a study among student midwives to examine their smoking behavior, their attitudes towards smoking, and their participation in prevention. METHOD: This was a descriptive cross-sectional study conducted from 15 January to 15 February 2018 using a self-administered questionnaire and included the student midwives of the University of Health Science at Libreville (Gabon). RESULTS: A total of 188 student midwives completed the questionnaires (70.7% of students of the 1st year, 15.0% of students of the 2nd year and 14.3% of students of the 3rd year). Gaps exist in the knowledge of student midwives regarding the risks of cigarette smoking in pregnancy and its role in the development of complications for the mother and foetus. Overall, 17.1% of student midwives think that smoking is responsible for the occurrence of ectopic pregnancies, 20.3% believe it is responsible for retro-placental haematoma, 17.6% for premature rupture of the membranes. The prevalence of smoking was 11.1% and was most frequent in 2nd year students (25.0%) and 3rd year students (14.8%) (P<0.023). The mean age of beginning smoking was 19.0±4.4 years. The main initiating factors were peer influence (28.6%), pleasure (19.0%) and stress (14.3%). Nicotine dependence was weak to moderate among 48.8% of smokers and absent in 52.2%. CONCLUSION: Gaps exist in the knowledge of student midwives regarding the risks of cigarette smoking to complications of pregnancy. There is need therefore to include formal training on tobacco control strategies at an early stage in the medical curriculum.

Lupus: evidence of environmental degradation? Assessment from 60 patients followed up in the Internal Medicine Department at the Libreville University Hospital, Gabon.

Lupus is an autoimmune disease of the connective tissue that occurs predominantly in women and blacks and whose expression is influenced by environmental factors, especially ultraviolet rays. The rising temperature in Gabon for nearly two decades led us to look for correlations between the onset of lupus, the patients' regions of origin, and environmental temperatures before and at diagnosis. retrospective, descriptive, and analytic study conducted in the Department of Internal Medicine of the CHU of Libreville (Gabon), from 01/01/2016 to 31/05/2016, based on the files of patients with diagnosed lupus receiving care in the department since 01/2002. Data collection forms listed for each patients age, sex, occupation, date and season of diagnosis, and place of residence (during childhood, adolescence, and adulthood). We looked for correlations between these data and temperatures, based on meteorological data from the country's seven main weather stations over a period from 1996 to 2015. The study included 53 women and 7 men (sex ratio 0.13), with a mean age of 32.7 +/- 8.9 years. The population included students (n = 25), civil servants (n = 15), the unemployed (n = 8), private-sector employees (n = 6), and shopkeepers (n=6). Diagnoses varied according to season, with 56.6% of the cases in the dry season and 43.4% in the rainy season. From 1 to 4 cases of lupus were diagnosed annually before 2011, 7 each year from 2011 to 2014, and at least 14 per year since 2015. Most patients (62.5%) had spent their childhood, adolescence, and adulthood in the country's capital (industrial zone par excellence), 17.8% in mining regions, and 12.5% in oil-drilling areas. The increase in the number of cases of lupus appears to be correlated with their greater prevalence in regions with higher temperature exposures, that is, in industrial, mining and petroleum regions, which are the regions of greatest exposure among our lupus patients.

Treatment of chronic inflammatory rheumatism by biotherapy in Gabon : eligibility and follow-up of the first 8 patients in sub-Saharan Africa.

OBJECTIVE: to clarify the eligibility criteria for biotherapies in patients with chronic inflammatory rheumatism (CIR) in sub-Saharan Africa and to describe the characteristics of the first 8 patients treated with biotherapy in Gabon. MATERIALS AND METHODS: Patients who responded inadequately to treatments by cDMARDs (EULAR criteria) had a face-to-face interview to inform them about and obtain their consent to biotherapy for at least 3 months, with details of the cost and side effects of each available biotherapy and a certificate of "necessity of biotherapy". The inclusion and follow-up of patients took place in the outpatient rheumatology consultations at the University Hospital of Libreville (Gabon) between January 2010 and December 2016. RESULTS: Of the 30 patients who failed cDMARDs and required biologic treatment, 8 (26.6%) were able to start a biotherapy: 4 men and 4 women with rheumatoid arthritis (n = 4.50%), spondyloarthritis or psoriatic rheumatism (n = 2.25% each). The biotherapy was etanercept (n = 4, 50%), adalimumab, golimumab, infliximab and rituximab (n = 1, 12.5% each). The average duration of the biotherapy was 27.4 months (9-54). Biotherapy was stopped in 4 cases (50%), one each (12.5%) for multifocal tuberculosis, pregnancy, financial reasons, and remission. CONCLUSION: Our study shows that biotherapies, which are currently very expensive, can be prescribed in Africa provided that the usual recommendations are followed strictly. Here, access to biotherapies is only possible through private insurance and the rheumatologist must play the role of facilitator for needy and consenting patients.

Sickle-cell disease with an eruptive appearance? What is your diagnosis?

Lupus is an autoimmune disease of the connective tissues, relatively frequent in the black population, and with a marked female prevalence. Clinical polymorphisms explain the diverse and varied nature of the clinical forms that are sources of diagnostic aberrations. This disease can be associated with various diseases. Here we report an unusual association with AS hemoglobinopathy.

Patients' Families' Perceptions of Lupus in Sub-Saharan Africa.

Lupus is an autoimmune disease affecting the connective tissue. Its clinical and biological polymorphism is often misunderstood by patients and families and can lead to treatment interruption and a decision to turn to alternative medicine. We used a questionnaire to assess the degree of knowledge of this disease of family members living with lupus patients. Of the 56 lupus patients receiving regular follow-up at our hospital, 123 members of 30 of their families (53.5%) participated. Overall, among these families, 81.5% of the participants perceived the disease as predominantly non-mystical, 72.3% as hereditary, 87.9% as non-contagious, and 60.9% as curable ; 90.2% considered it compatible with pregnancy, another 90.2% with work, and 73.9% with sports activity. The principal clinical signs mentioned involved joint (22.7%), skin (13%), and finger-related (11.3%) disorders, with renal disease (9.7%), heart disease (8.1%), and general signs (8.1%) mentioned most frequently as the main complications. The best-known medications for disease control were corticosteroids (20.3%) and hydroxychloroquine (17%). Family members considered non-adherence (53.6%) the most frequent factor in disease flares. More than half were unaware of the life expectancy associated with this disease, but 30.1 % thought it was lower than that of the national population of Gabon - 70 years. Only 64 (52%) of the respondents had seen documentation about lupus, mostly through the Internet (65.6%). Lupus is not a disease that families know and understand well.

Leptospirose, une étiologie de fièvre prolongée peu diagnostiquée. A propos d'une observation

Les conditions bio-climatiques prédisposent à la transmission de la leptospirose au Gabon. Paradoxalement, cette affection est rarement voire peu diagnostiquée par les praticiens de ce pays. Nous rapportons une observation de leptospirose révélée par une fièvre au long cours

Assessment of Imatinib in the treatment of chronic myeloid leukemia in Gabon: a cohort of 17 cases.

The prognosis for chronic myeloid leukemia, the first hematologic malignancy for which successful targeted therapy has been developed, has changed markedly in the West. In developing countries, however, prognosis remains poor, mainly because of lack of access to treatment. The effort made by some nongovernmental organizations to distribute first-generation tyrosine kinase inhibitors free of charge has changed this situation in some regions, notably in sub-Saharan Africa and Gabon in particular. We report the results in a cohort of 17 patients.

[Tuberculosis of the breast: four cases report at the Armies Instruction's Hospital Omar Bongo Ondimba (HIAOBO) in Libreville (Gabon)]. / Tuberculose mammaire : à propos de quatre cas à l'hôpital d'instruction des armées Omar Bongo Ondimba (HIAOBO) de Libreville (Gabon).

Mammary tuberculosis is a rare localization of extra pulmonary tuberculosis. Its frequency increases proportionally with the HIV pandemic. We report four cases of breast tuberculosis diagnosed in the general medicine department of HIAOBO including two with positive HIV serology. It is necessary to know this extra pulmonary form/feature as the differential diagnosis with breast tumors is sometimes difficult.

Caractéristiques cliniques de la bronchopneumopathie chronique obstructive à l'Hopital d'Instruction des Armées Omar Bongo Ondimba

Il s'agit d'une étude rétrospective menée sur cinq ans à l'hôpital d'instruction des armées Omar Bongo Ondimba au cours de laquelle nous avons obtenu les résultats suivants : une prévalence de 0,78.Une prédominance masculine (68,9%), avec un âge moyen de 66 ans chez des patients présentant des co-morbidités à type de diabète (6,6%) et d'HTA (36,34%). La majorité des patients était des sans-emploi (31,45%). Les antécédents tabagiques (principale étiologie) étaient retrouvés dans 85% des cas avec 70% de fumeurs actifs et une consommation moyenne de 24±18 paquets/année.Le motif de consultation le plus fréquent était la dyspnée (50,8%) alors que le facteur favorisant prédominant était le tabac (83,6%). Mais les infections (surtout tuberculeuse) vienaient en seconde position (9,84%). L'anomalie radiologique la plus fréquente était l'emphysème centro lobulaire (30,51%). Les patients étaient pour la plupart au stade II (57,4%). Ils avaient quasiment tous bénéficié de beta 2 mimétiques (95,08%) et de corticothérapie inhalées (91,80%).La BPCO est une maladie chronique évolutive dont la principale cause reste le tabac (surtout en Occident). Mais la pollution et les infections post tuberculeuses ne doivent pas être négligées dans les pays en voie de développement. Ceci nécessite de la part des pouvoirs publics une mobilisation des ressources humaines et financières avec intégration de la BPCO dans le programme de santé publique. Le dépistage (peak Flow dans les salles de consultation) et la prise en charge des patients doivent être assurés. Il faut élaborer un cadre législatif anti-tabac et renforcer les moyens préventifs et thérapeutiques de la lutte contre la tuberculose

Apport du Crag-Test serum dans le diagnostic de la cryptococcose neuroméningée en milieu rural. A propos de deux observations

Introduction : La cryptococcose neuro-méningée est la plus commune des affections mortelles du Système Nerveux Central chez les patients immuno-déprimés en Afrique Subsaharienne. Il s'agit alors d'une véritable urgence diagnostique et thérapeutique, d'où la mise en œuvre des tests diagnostiques rapides et efficace. Le Crag-Test serum (Antigénémie cryptococcique) pourrait alors se révéler utile sur ces terrains particuliers en milieu rural africain. Observation : Nous rapportons deux cas de cryptococcose neuro-méningée chez deux patientes âgées respectivement de 48 et 38 ans au regard du terrain d'immuno-dépression acquis, la présence de levure encapsulée à l'examen du liquide cérébro-spinal à l'encre de Chine dans un cas et la positivité du Crag-test serum dans les deux cas. La présence d'emblée de facteurs de mauvais pronostic expliquaient l'issue fatale. Conclusion : Compte tenu de la gravité potentielle de cette affection, le Crag-test serum devrait être facilement accessible et disponible pour un diagnostic rapide et une prise en charge précoce et efficace afin de limiter la morbi-mortalité

[Breast cancer in men: about 3 cases at the l'Hôpital d'instruction des armées Omar Bongo Ondimba (HIAOBO) (Gabon)]. / Cancer du sein chez l'homme: à propos de trois observations à l'Hôpital d'instruction des armées Omar Bongo Ondimba (HIAOBO) (Gabon).

We report three cases of breast cancer in men observed at Military Teaching Hospital Omar Bongo Ondimba between January 2008 and December 2009, under varying circumstances, with all unfavorable evolution.

[Intrathoracic giant peripheral nerve sheath tumor during Von Recklinghausen disease]. / Tumeur nerveuse géante du thorax au cours de la maladie de Von Recklinghausen.

We report the case of a patient aged 23, admitted for bilateral intrathoracic tumor, including a giant right. Surgery was performed by right sternothoracotomy. After 7 days, she presented an irreversible cardiac arrest. The malignant peripheral nerve sheath tumors are rare and aggressive. Their incidence is 0.001% in the general population and 0.16% in patients with neurofibromatosis type 1. These tumors are characterized by their risk of recurrence and poor prognosis. The treatment is the surgical resection. We analyze incidence, diagnosis and prognosis of these tumors.
