RESUMO
To review the practice of anesthesia in Conakry hospitals This multicenter descriptive study focused on the practice of anesthesia in Conakry hospitals. We selected 9 healthcare facilities: 6 public and 3 private hospitals. Together, these hospitals had 23 operating theaters, of which 11 (47.8 %) had an anesthesia machine, while 12 (51.9 %) did not have an oxygen supply. Six (26.1 %) had a complete intubation platform. For monitoring, we observed a multiparametric scope in five (21.7 %) of the operating rooms and a pulse oximeter in five. The anesthesia products used most frequently were: ketamine (narcotic), fentanyl (opioid), vecuronium (neuromuscular blocking agent), halothane (volatile anesthetic), and bupivacaine (local anesthetic). These nine facilities have 51 professional anesthesia practitioners: 44 (86.27%) senior technicians in anesthesia-resuscitation, and 7 (13.73 %) physicians specialized in anesthesiology and resuscitation. Over a one-year period (2016), 6303 patients received anesthesia. Gynecology-obstetrical surgery accounted for the highest proportion of patients receiving anesthesia (43.47 %). General anesthesia without intubation was the most common anesthetic technique (67.5 %). Most incidents were intraoperative and cardiovascular (95.6 %). The mortality rate was 0.4 %. Better technical platforms and better training of young practitioners would improve the practice of anesthesia in Guinea.

In developing countries, tetanus remains a public health problem because of its frequency, severity, and still high mortality. The objective of this study was to describe the epidemiological profile of patients hospitalized for tetanus and to identify the factors associated with dying from it. This retrospective, descriptive, and analytical study reviewed hospital records of all patients, of all ages and genders who were treated for tetanus in our department over a 5-year period. Among 3549 patients during the study period, 75 had tetanus (2.11%), and 71 of them were included in our study. The median age of patients was 35 years (range: 11-70 years) with a male prevalence of 80%. The most frequently affected socio-professional categories were students (21.1%), farmers (18.3%), workers (15.5%), and shopkeepers and tradespeople (15.5%). The main entry points were post-traumatic (40.9%), cutaneous (33.8%), and post-surgical (16.90%). Paroxysm (95.8%), trismus (93.0%), generalized contracture (67.6%), and dysphagia (46.5%) were the most frequent signs. Among these cases, 40.9% were severe (40.85%), 49.3% moderate (49.30%), and 9.6% benign. We recorded 34 deaths (48%). Factors associated with death were age> 60 years (P = 0.01), fever (P = 0.01), hypertension (P = 0.02), and HIV infection (P = 0.01). Tetanus remains a frequent disease with high lethality. Death is associated with specific factors that should be taken into account in the criteria for assessing its prognosis.

The objective of this study was to determine the factors associated with death in patients hospitalized for tetanus. This study collected prospectively over a twelve (12) month period, the epidemiological, clinical and evolutionary data, and proceeded to an analysis of the factors associated with the death of hospitalized patients. We collected 32 patients with tetanus, or 5% of the total number of hospitalized patients. The average age was 36 ± 14 years. The sex ratio was 15 (30/2). The iatrogenic entrance door was found in 5 (15%) patients. Respiratory complications were the most frequent, ie 9 cases (28%). The most commonly used treatment regimen (28 cases, 88%) was the combination of metronidazole, diazepam, and anti-tetanus serum with an average hospital stay of 23 days. A Dakar prognostic score greater than or equal to 3, the presence of complications and a hospital stay of less than or equal to 7 days were the main factors associated with the death. Tetanus remains common in Guinea with a high lethality rate. Improving immunization coverage is imperative.
L'objectif de cette étude est d'analyser les facteurs associés au décès chez les patients hospitalisés pour tétanos. Cette étude a recueilli de façon prospective, sur une période de 12 mois, les données épidémiologiques, cliniques et évolutives, puis procédé à une analyse des facteurs associés au décès des patients hospitalisés. Nous avons colligé 32 patients atteints de tétanos, soit 5 % du total des patients hospitalisés. L'âge moyen était de 36 ± 14 ans. Le sex-ratio était de 15 (30/2). La porte d'entrée iatrogène a été retrouvée chez 5 (15 %) patients. Les complications respiratoires étaient les plus fréquentes, soit 9 cas (28 %). Le schéma de traitement le plus utilisé (28 cas, 88 %) a été l'association de métronidazole, de diazépam et de sérum anti-tétanique avec une durée moyenne d'hospitalisation de 23 jours. Un score pronostique de Dakar supérieur ou égal à 3, la présence de complications et une durée d'hospitalisation inférieure ou égale à 7 jours ont été les principaux facteurs associés au décès. Le tétanos reste fréquent en Guinée avec un taux de létalité élevé. L'amélioration de la couverture vaccinale est impérative.
RESUMO
INTRODUCTION: The incidence of stroke is rising in developing countries. In Côte d'Ivoire, it accounts for nearly 45 % of admissions to the neurology departments in Abidjan. In Bouaké, no study has dealt with this subject since peace returned. Our aim was to assess the epidemiological characteristics of stroke patients at Bouaké University Hospital. METHODOLOGY: This cross-sectional study took place from September 2013 to December 2015 and included all patients hospitalized for a stroke confirmed by brain imaging. RESULTS: The study included 164 cases: 60% ischemic strokes, and 40 % hemorrhagic. Patients' mean age was 62 years with a sex ratio of 0.66. Patients not in the labor force accounted for the largest portion (61.6 %). The interval between the stroke and admission to the neurology department ranged between 24 and 72 hours for 61 % of the patients. The main risk factor was hypertension (62.8 %). The average length of hospitalization was 8.44 days. Hospital mortality was 18.3 %. CONCLUSION: Stroke is responsible for high morbidity and mortality in the neurology department of Bouaké University Hospital.

BACKGROUND: In vitamin A-deficient populations, children hospitalized with infections and/or malnutrition are at particular risk of developing severe vitamin A (VA) deficiency. High-dose VA supplements are recommended as part of the treatment but results on its effect on recovery from morbidity and on prevention from nosocomial morbidity are conflicting. OBJECTIVE: We aimed to assess the effect of a single high dose and daily low dose of VA on hospitalized malnourished children's morbidity. DESIGN: We carried out a double-blind, randomized trial in 604 and 610 Senegalese hospitalized children. The first mentioned batch received a high-dose VA supplement (200,000 IU) on admission, the second a daily low-dose VA supplement (5000 IU per day) during hospitalization. Children were followed up until discharged. Data on all-cause morbidity were collected daily. RESULTS: Survival analysis showed that the incidence of respiratory disease was significantly lower in the low-dose group than in the high-dose group, hazard ratios (HR): 0.26, 95% CI: 0.07-0.92. The duration of respiratory infection was also significantly lower in the low-dose group than in the high-dose group (HR of cure: 1.41, 95% CI: 1.05-1.89). Duration and incidence of diarrhoea were not significantly different between treatment groups. In children with oedema on admission, mortality was significantly lower in the low-dose group (Adjusted odds ratio: 0.21; 95% CI: 0.05-0.99). CONCLUSIONS: Daily low dose of VA compared with single high dose significantly reduced duration and incidence of respiratory infection but not of diarrhoea in hospitalized children.

BACKGROUND: Acute respiratory infections (ARI) are the leading cause of death in childhood. Most of children's deaths happen at home without health level first cares. However in Senegal only health workers are allowed to prescribe antibiotics. A competency-based training was developed to improve and assess the management of acute respiratory infections in young children aged 2 to 59 months by low level educated community health workers (CHWs) in 4 districts of Senegal. The first findings showed the CHWs capable of acquiring the skills needed to effectively manage ARI cases in accordance with the World Health Organization's ARI case management strategy. The aim of this study was to assess the quality of their management after a 1 year follow-up. METHODS: We provided to CHWs 3 days course in ARI management. After the 3-day course, a 4-month follow-up was performed. We organized a 1-day refresher course every month and in every district. In order to assess the quality of management of CHWs we analyzed the management process and compared the CHWs classification to the classification of the first level health facilities. RESULTS: Twenty-three percent (3727/15,965) of IRA cases of district were managed by CHWs. Ninety percent (2738/3042) among them were well classified, well managed and well followed-up. But 28% of severe pneumonia cases were misclassified as pneumonia. About treatment, 22.5% of 'cough or cold' got wrong treatment with cotrimoxazole and 10.3% of severe pneumonia got cotrimoxazole without referral. Less than half of severe pneumonia benefited of the first follow-up and only 18% of the second. CONCLUSIONS: The results highlight that a CHWs low-level educated in French, trained and followed-up could apply the WHO algorithm of IRA management. They could help to give proximal care related to children ARI, to the community. But it seems useful of emphasizing the recognition of danger signs and the follow-up of severe cases.

INTRODUCTION: Peripheral facial paralysis (PFP), a frequent complication during infection with the human immunodeficiency virus (HIV), is a major cause of morbidity for these patients. The aim of this study was to show the place of unilateral PFP in the discovery of HIV infection in tropical areas. MATERIAL AND METHODS: This is a descriptive cross-sectional study with prospective data collection over a 12-month period, in the ENT departments of the Ignace Deen National Hospital and Neurology Hospital of the Sino-Guinean Friendship Hospital (CHU de Conakry). RESULTS: Of the 2517 patients received during the study period, 64 had PFP, a prevalence of 2.54%. HIV serology was performed in 56 patients, 24 of whom had a positive serological reaction, a prevalence of 42.86%. The young adult population was the most exposed, with an average age of 34.5 years. There were 9 men and 15 women, or a sex ratio of 0.6. In 70.83% of cases, the consultation period occurred between the 1st and 3rd week. Unilateral facial asymmetry and persistent opening of the palpebral fissure were the main clinical signs. A total of 75% of our patients were infected with HIV1. CD4 levels ranged from 175 to 400/mm3. All our patients had received PFP and HIV treatments. The evolution was marked by a complete recovery with no sequelae of PFP in 62.5% of cases. CONCLUSION: The occurrence of isolated PFP in apparently healthy adults should suggest seroconversion to HIV. The prognosis of these PFPs is often good despite the delay in diagnosis.
INTRODUCTION: La paralysie faciale périphérique (PFP), complication fréquente au cours de l'infection par le virus de l'immunodéficience humaine (VIH), constitue une cause importante de morbidité chez ces patients. Le but de cette étude était de montrer la place de la PFP unilatérale dans la découverte de l'infection par le VIH en zone tropicale. MATÉRIEL ET MÉTHODES: Il s'agit d'une étude transversale descriptive avec collecte des données prospective, sur une période de 12 mois, réalisée dans les services d'ORL de l'Hôpital National Ignace Deen et de Neurologie de l'hôpital de l'amitié Sino-Guinéenne (CHU de Conakry). RÉSULTATS: Sur les 2517 patients reçus en consultation durant notre période d'étude, 64 présentaient une PFP soit une prévalence de 2,54%. La sérologie VIH avait été réalisée chez 56 patients, dont 24 avaient eu une réaction sérologique positive, soit une prévalence 42,86 %. La population adulte jeune était la plus exposée, avec un âge moyen de 34,5 ans. Il s'agissait de 9 hommes et 15 femmes, soit un sex-ratio de 0,6. Le délai de consultation était, dans 70,83% des cas, situé entre la 1ère et 3ème semaine. L'asymétrie faciale unilatérale et la persistance d'ouverture de la fente palpébrale étaient les principaux signes cliniques. Au total 75 % de nos patients étaient porteurs du VIH1. Le taux de CD4 variait entre 175 et 400/mm3. Tous nos patients avaient bénéficié d'un traitement de la PFP et du VIH. L'évolution avait été marquée par la récupération totale et sans séquelle la PFP dans 62,5% des cas. CONCLUSION: La survenue d'une PFP isolée chez l'adulte apparemment en bonne santé, doit faire évoquer une séroconversion au VIH. Le pronostic de ces PFP est souvent bon malgré le retard diagnostic.
RESUMO
Female genital mutilation (FGM) comprises all procedures involving partial or total removal of the external genitalia and/or any other procedures affecting the female genitalia, for cultural or religious reasons or for nontherapeutic purposes in general. FGM is responsible for a number of short-, medium-, and long-term complications that can engage the vital and functional prognosis, especially in African countries. We report on a case in a 10-year-old girl who underwent genital mutilation, a traditional type of total excision during the neonatal period. She was followed for urethral meatus stenosis, which then was complicated by obstructive chronic kidney failure and urinary sepsis, whose progression was fatal.

BACKGROUND: Aflatoxins are fungal metabolites that frequently contaminate staple foods in much of sub-Saharan Africa, and are associated with increased risk of liver cancer and impaired growth in young children. We aimed to assess whether postharvest measures to restrict aflatoxin contamination of groundnut crops could reduce exposure in west African villages. METHODS: We undertook an intervention study at subsistence farms in the lower Kindia region of Guinea. Farms from 20 villages were included, ten of which implemented a package of postharvest measures to restrict aflatoxin contamination of the groundnut crop; ten controls followed usual postharvest practices. We measured the concentrations of blood aflatoxin-albumin adducts from 600 people immediately after harvest and at 3 months and 5 months postharvest to monitor the effectiveness of the intervention. FINDINGS: In control villages mean aflatoxin-albumin concentration increased postharvest (from 5.5 pg/mg [95% CI 4.7-6.1] immediately after harvest to 18.7 pg/mg [17.0-20.6] 5 months later). By contrast, mean aflatoxin-albumin concentration in intervention villages after 5 months of groundnut storage was much the same as that immediately postharvest (7.2 pg/mg [6.2-8.4] vs 8.0 pg/mg [7.0-9.2]). At 5 months, mean adduct concentration in intervention villages was less than 50% of that in control villages (8.0 pg/mg [7.2-9.2] vs 18.7 pg/mg [17.0-20.6], p<0.0001). About a third of the number of people had non-detectable aflatoxin-albumin concentrations at harvest. At 5 months, five (2%) people in the control villages had non-detectable adduct concentrations compared with 47 (20%) of those in the intervention group (p<0.0001). Mean concentrations of aflatoxin B1 in groundnuts in household stores in intervention and control villages were consistent with measurements of aflatoxin-albumin adducts. INTERPRETATION: Use of low-technology approaches at the subsistence-farm level in sub-Saharan Africa could substantially reduce the disease burden caused by aflatoxin exposure.

A case-control study was conducted between September 2003 and January 2004. Fifty four newborn babies born before 37 weeks of gestation resulting from 47 pregnancies including 7 multiple pregnancies were compared to 105 newborn babies born between 37 and the 42 weeks of gestation. Parturient geographical origin, marital status, age, alcohol or tea consumption and height were not significantly associated to premature birth (p > 0.05). On the other hand, a higher parity or equal to 3, a number of antenatal care lower than 3 were significantly associated with the risk of premature birth (p < 0.05). But a gestity and a parity lower than 3 and a number of antenatal consultations higher or equal to 3 had a protective effect (OR < 1; p < 0.05). We recommend a reinforcement of malarial prevention during pregnancy according to WHO recommendations and the improvement of the quality of the antenatal care in the Ziguinchor medical district.

AIM OF THIS STUDY: to evaluate the efficacy of kangaroo method on thermoregulation and weight gain of a cohort of preterm. METHODS: it is a retrospective study based on files of preterm baby weighting below 2000 g, included after discharge to neonatal unit of Aristide Le Dantec maternity for kangaroo method care. Efficiency was appreciated on thermic curve evolution and daily weight gain. RESULTS: 56 preterm babies were including. Mean gestational age was 33 +/- 7,6 weeks and mean birth weight, 1488 +/- 277,6 g (median = 1500 g). Mean temperature was satisfying during follow up and was stable around 37 +/- 0,5 degrees C at discharge of program with mean daily weight gain of 33 +/- 7,6 g. We had only one case of death. CONCLUSION: The results of this study point out efficacy of kangaroo method on thermoregulation, weight gain and survival of preterm babies. We advocate for promotion in developing countries because of its low cost.

BACKGROUND: Beckwith-Wiedemann syndrome is a congenital syndrome with variable phenotypic expression. It is less commonly described in Africa. We report a case in Dakar universitary hospital center. OBSERVATION: This report is about a two month old child from Mauritania presenting an hemihypertrophy, macroglassia and an umbilical hernia. Glycemia was under normal level showing a mild hypoglycemia (0,6 g/dl). T3, T4 and TSH values were in normal range. Abdominal echography was normal. Our patient was stable at the first clinical examination. CONCLUSION: we advocate for dietetic measures and rigorous clinical follow up, every 3 to 6 month, to screen for recurrent hypoglycaemia and the occurence of an eventual neoplasmic desorders.

OBJECTIVES: This study aimed to determine the hospital prevalence rate of tetanus in women of childbearing age in the infectious disease department of Donka CHU in Conakry and to describe their sociodemographic characteristics and outcomes. METHODOLOGY: This descriptive retrospective study examined the records of all patients aged 15 to 495 years hospitalized for tetanus over a 10-year period. RESULTS: During the study period, 74555 patients were hospitalized - 239 for tetanus. In all, 22 woman of childbearing age had tetanus, that is, 9.2%. Their mean age was 325 years. Most of the women were married (13/22) and lived in Conakry (18/22); 165 were housewives, and 65 patients had begun but not completed the required vaccinations. The incubation period was >75 days for 165 patients. Tetanus infection resulted from medical procedures for 9 women and trauma for 6. We recorded 125 deaths. The average duration of hospitalization was 215 days. CONCLUSION: Preventing tetanus requires a reinforcement of vaccination drives and especially the implementation of policies for booster reminders.

Anthrax disease is an anthropozoonosis caused by a Gram-positive bacterium, Bacillus anthracis. Our objective was to describe the epidemiological, clinical and therapeutic features of the 2014 epidemic in Koubia prefecture. This retrospective study examined all of the anthrax cases reported in Fafaya, Koubia Prefecture. In March and April 2014, there were 39 cases of human anthrax reported, for an incidence of 1.135%. The mean age was 20.9 (± 18.3) with a sex ratio of 2.54 (28/11) in favor of men. Seventy-six percent (23/39) were single. More than one half were students (53.8%). The main clinical signs were fever in 71, 8% (n = 28 /), papules 59% (n = 23), vesicles of 59% (n = 23) Digestive and cutaneous signs represented 35.9 % and 64.1% respectively; 35% had ingested contaminated meat and 17.95% were in direct contact with a sick animal. We didn't find any correlation between the mode of infection and onset of signs. The fatality rate was 28.21%. The 2014 epidemic of anthrax disease in the Koubia prefecture was marked by a high incidence and lethality. Clinical manifestations were cutaneaous and digestive. These results may serve further interventions to fight against anthrax disease. They should mainly focus on an awareness of peasants, surveillance and vaccination of cattle. Other studies seem to be necessary.

INTRODUCTION: Nephrotic syndrome represents a significant part of chronic kidney disease in Black Africa. Our work aimed to determine the frequency and type of kidney lesions in an adult carrying pure nephrotic syndrome. PATIENTS AND METHODS: We conducted a prospective and descriptive study (2003-2004), 40 patients were recruited on the basis of the presence of a pure nephrotic syndrome. Proteinuria was plentiful, selective to albumin greater than 3 g/24h, not accompanied by hematuria, or high blood pressure, or kidney failure. Cases of bacterial, parasitic and viral infections (hepatitis B, C, HIV) were excluded. By following contra-indications of renal biopsy, samples were taken under local anesthesia by means of percutaneous lumbar and fixed in two tubes, one containing "Michel's medium" and the other 12% Formalin. These techniques and readings were carried out in the pathological anatomy Laboratories of Nantes (France) and Conakry (Guinea). RESULTS: There were 24 men and 16 women with an average age of 26.2 ± 8 years [range: 20-51]. Clinical symptoms were dominated by weight gain characterized by edema. Proteinuria was between 3-3.5 g/24h in 16 (40%); between 3.6-5 g in 2 cases (5%) and greater than 5 g/24h in 22 cases (55%). The number of glomeruli was on average 11 ± 9 [range: 3-36]; glomerular permeability was on average 10.4 ± 10. Renal impairment was glomerular in 22 cases, tubulointerstitial in 12 cases and vascular in 6 cases. Immunofixation was positive in 30/40 cases for IgA IgG IgM; in 26 cases for C1q C3; in 4 cases for C1q C3 C4; and finally for fibrin in 28 cases. Histological renal lesions were FSGS (40%), MDC (35%), MGN (5%), MPGN (5%) and undetermined (15%). CONCLUSION: A regular practice of renal anatomopathological examination "on the spot" will lead us to carefully assess the causes of kidney failure associated with nephrotic syndrome.
INTRODUCTION: Le syndrome néphrotique représente une part importante d'insuffisance rénale chronique en Afrique noire. Notre travail avait pour but de déterminer la fréquence et le type de lésions histologiques rénales chez un adulte porteur d'un syndrome néphrotique pur. PATIENTS ET MÉTHODES: Au cours d'une étude prospective et descriptive (20032004), 40 patients ont été sélectionnés sur la base de la présence d'un syndrome néphrotique pur. La protéinurie était abondante, sélective à l'albumine, supérieure à 3 g/24h, non accompagnée d'hématurie, ni d'hypertension artérielle, ni d'insuffisance rénale. Les cas d'infections bactériennes, parasitaires et virales (hépatites B, C, HIV) ont été volontiers exclus. En respectant les contre indications de la biopsie rénale, les prélèvements ont été effectués sous anesthésie locale, par voie lombaire percutanée, puis fixés dans deux tubes dont un contenait du « liquide de Michel ¼ et l'autre du Formol à 12%. Les techniques et lectures ont été effectuées aux Laboratoires d'anatomie pathologique de Conakry (Guinée) et de Nantes (France). RESULTATS: Il s'agissait de 24 hommes et de 16 femmes âgés en moyenne de 26,2 ± 8 ans [2051]. La symptomatologie clinique était dominée par une prise de poids marquée par les Ådèmes. La protéinurie était comprise entre 33,5 g/24h dans 16 cas (40%); entre 3,65 g dans 2 cas (5%) et supérieure à 5 g/24h dans 22 cas (55%). Le nombre de glomérules était en moyenne de 11 ± 9 [336]; la perméabilité des glomérules était en moyenne de 10,4 ± 10. L'atteinte rénale était glomérulaire dans 22 cas, tubulo-interstitielle dans 12 cas et vasculaire dans 6 cas. L' immunofixation a été positive dans 30 cas /40 pour les IgA IgG IgM; dans 26 cas pour C1q C3; dans 4 cas pour C1q C3 C4; et en fin pour la fibrine dans 28 cas. Les lésions histologiques rénales étaient une HSF (40%), une LGM (35%), une GEM (5%), une GNMP (5%) et indéterminée (15%). CONCLUSION: Une pratique régulière de l'examen anatomo-pathologique rénal «sur place" nous amènerait à apprécier judicieusement les causes d'insuffisance rénale en rapport avec un syndrome néphrotique.
RESUMO
UNLABELLED: Human Immunodeficiency Virus (HIV) infection prevalence rate is estimated at 1.4% in Senegal, and about 3,000 children could be infected. HIV positive children are followed up since 2000 in Albert Royer Hospital (Dakar, Senegal). OBJECTIVES: To describe clinical and epidemiological aspects of HIV paediatric infection, and to evaluate the implementation of high active antiretroviral therapy in HIV positive children in our country. POPULATION AND METHODS: Over a period of three years, the medical reports of 98 infected patients have been collected, 96% with HIV 1 infection. RESULTS: Most of the patients had a maternally transmitted HIV infection (99%). At their enrollment, the median age was 60 months; malnutrition (79%), persistent lymphadenopathy (65%) and skin lesions (64%) were the common clinical manifestations. Thirty-nine percent of the patients were in class C (CDC) and 81% had CD4 cell count< or =25%. Median viral load were 421,852 copies/ml at presentation. Seven infants had a rapid progressive disease with encephalopathy. Thirty-six patients received high active antiretroviral therapy with high observance and good tolerance. CONCLUSION: This study allowed to define clinical and biological profile of paediatric HIV infection in our country and to update the implementation of high active antiretroviral therapy.

UNLABELLED: Inpatient mortality is an indicator of the quality of care. We analyzed the mortality of under 5-year-old hospitalized children in the pediatric ward of Aristide Le Dantec Hospital for updating our data 10 years after our first study. METHODS: We analyzed the data of the children hospitalized between 1 January and 31 December 2012. For each child, we collected anthropometric measurements converted to a z-score related to World Health Organization growth data. Logistic regression-generating models built separately with different anthropometric parameters were used to assess the risk of mortality according to children's characteristics. RESULTS: Data from 393 children were included. The overall mortality rate was 10% (39/393). Using logistic regression, the risk factors associated with death were severe wasting (odds ratio [OR]=8.27; 95% confidence interval [95% CI]) [3.79-18], male gender (OR=2.98; 95% CI [1.25-7.1]), dehydration (OR=5.4; 95% CI [2.54-13.43]) in the model using the weight-for-height z-score; male gender (OR=2.5; 95% CI [1.11-5.63]), dehydration (OR=8.43; 95% CI [3.83-18.5]) in the model using the height-for-age z-score; male gender (OR=2.7; 95% CI [1.19-6.24]), dehydration (OR=7.5; 95% CI [3.39-16.76]), severe deficit in the weight-for-age z-score (OR=2.4; 95% CI [1.11-5.63]) in the model using the weight-for-age z-score; and male gender (OR=2.5; 95% CI [1.11-5.63]) and dehydration (OR=8.43; 94% CI [3.83-18.5]) in the last model with mid-upper arm circumference (MUAC). Dehydration and malnutrition were two independent risk factors of death. The protocols addressing dehydration and malnutrition management should be audited and performed systematically for each child's anthropometric measurements at admission.

Aflatoxins and hepatitis B virus (HBV) are major risk factors for hepatocellular carcinoma (HCC) in high incidence areas for this cancer, namely southeast Asia and parts of Africa. There is evidence from both epidemiological studies and animal models that the two factors can act synergistically to increase the risk of HCC. The cellular and molecular mechanism of the interaction between these two factors is as yet undefined. However, one possible mechanism attested to by studies in HBV transgenic mice is that chronic liver injury alters the expression of specific carcinogen metabolising enzymes thus modulating the binding of aflatoxin to DNA in hepatocytes. The high levels of aflatoxin exposure which occur in many areas of the world where chronic HBV infection is endemic indicate that measures to reduce aflatoxin exposure would contribute to reducing HCC incidence. In preliminary studies, Guinea-Conakry have established baseline data for the implementation of a community-based intervention study to evaluate the effectiveness of improved post-harvest processing and storage of the groundnut crop, a major source of aflatoxins. Aflatoxin-albumin adducts were measured in 423 sera from individuals living in the four natural geographic zones of Guinea. More than 95% of the serum samples were positive for this biomarker and highest exposures were found in Lower Guinea where groundnuts are consumed as a dietary staple. Variations in mean levels between villages within a geographic region did not vary greatly. HBV infection was endemic in all regions with an overall prevalence of 16.7% chronic carriers. Thus in this population both HBV vaccination and reduction in aflatoxin exposure would be beneficial in decreasing morbidity and mortality from liver disease.

BACKGROUND: Acute respiratory infections are the leading cause of death in childhood and most child deaths in Senegal occur at home without qualified health care. Despite this situation, only qualified healthcare workers are authorized to prescribe antibiotics. A competency-based training program was developed to improve and assess management of acute respiratory infections in young children aged between 2 and 59 months by low-level educated community health workers (CHWs) in four districts of Senegal. METHODS: In accordance with the strategy developed by the World Health Organisation, educated low-level community health workers in four district of Senegal were given a three-day course on the management of acute respiratory failure. We assessed the effects of the course by comparing pre-training and post-training skills with the Students t test. RESULTS: The results showed that the educated low-level community health workers were capable of acquiring the skills needed to effectively manage children with acute respiratory failure. CONCLUSION: Further evaluation is needed to determine the mid- and long-term effects of the course and supervised post-training activities.
