From farmers to livestock keepers: a typology of cattle production systems in south-western Burkina Faso.

Cattle production is an essential livelihood strategy in south-western Burkina Faso. Although having a distinct cultural role and known to be resistant against African animal trypanosomosis, the Lobi taurine cattle breed is endangered due to its low market value. As the first step in preservation efforts, our study aimed to develop a typology of production systems at the farm level. We used a structured questionnaire and focus group discussions for collecting data on household characteristics, socioeconomic activities, livestock, and access to services. The sample comprised 169 households in three communities. The analytical strategy included factor analysis of mixed data and hierarchical clustering. We identified four distinct types of cattle production systems: (1) sedentary Lobi farms, (2) sedentary crossbreed farms, (3) semi-transhumant Fulani zebu farms, and (4) transhumant Fulani zebu farms. Significant factors in developing this typology were the farmers' ethnic group, crop diversity, cattle herd size, cattle herd composition, number of small ruminants, and livestock management strategies. Across all production systems, men were considered being primary decision-makers in cattle production, with women, herders, and children being responsible for specific tasks. All identified production systems are increasingly confronting disease pressure and scarcity of water and land. Future efforts in preservation and breeding will need to respond to these trends in the agroecosystem, integrate risk management measures, and resonate with the specific needs of the different household members involved in cattle rearing.

[Epidemiology of maxillo-facial traumatism s sequels at stomatology and maxillo-facial surgery service of Yalgado Ouedraogo University Hospital Center]. / Epidémiologie des séquelles de traumatismes maxillo-faciaux au service de stomatologie et chirurgie maxillo-faciale du Centre Hospitalier Universitaire Yalgado Ouedraogo (Burkina Faso).

Introduction: Our study brings back the epidemiological and anatomo-clinical characteristics of the maxillo-facial traumatisms sequels at Yalgado Ouedraogo University Hospital Center of Ouagadougou. Methodology: It was a transversal descriptive study going from May 2013 to April 2015. Results and Discussion: In all, 152 cases of post traumatisms sequels were collected. The masculine sex was more affected with a sex-ratio of 2,53. The mean age was 30,80 years. The public road accidents (73,68%) were the main etiology of initial lesions. The isolated functional and morphological sequels respectively represented 1/3 and 1/6 of cases. Half of patients had mixed sequels. The odontological sequels (41,45%), the disgracious scars (93,68%), the neurological sequels (15,79%), the ocular sequels (11,18%), and the temporo-mandibular ankylosis were the main sequels found in our study. These sequels could be explained by the nature of initial lesions and the lateness of consultations. Conclusion: Development of population's awareness and close interdisciplinary collaboration helped to reduce the frequency of these sequels.

[Tooth decay: epidemiological and therapeutic aspects in dental service of University Teaching Hospital Yalgado Ouedraogo and Municipal Centre of Oral Health]. / La carie dentaire: aspects épidémiologiques et thérapeutiques aux services de chirurgie dentaire du Centre Hospitalier Universitaire Yalgado Ouedraogo et du Centre Municipal de santé bucco-dentaire.

INTRODUCTION: In order to improve the prevention and treatment of dental caries in Burkina Faso, we conducted a study on the epidemiological and therapeutic aspects of dental caries in the dental services of University Teaching Hospital Yalgado Ouedraogo and in the Municipal Centre of Oral Health of Ouagadougou. MATERIAL AND METHODS: A prospective and descriptive study from October, 15th 2012 to January, 15th 2013 was conducted on a sample of 191 patients. The variables recorded were: patient's identity, age, sex, area of residence, food mode, socioeconomic level, reason for consultation, oral hygiene, DMFT index, degree of tissue damage, the topography of the carious lesions and the applied therapy. RESULTS: Caries prevalence was 93.19% more female consultations, with sex ratio at 0.77. The average age was 31 years for a sample often engaged in trade and the informal sector. Carious lesions were usually limited to less than 4 teeth. The main motivation for the consultation was pain at 82.20%. CONCLUSION: The use of preventive care is quite low in our population. Extractions still occupy an important part of treatment. We need to improve oral hygiene and show to patients the necessity of routine visits to the dentist every year for early treatment.

[Epidemiology and clinic of dental extractions in University Teaching Hospital Yalgado Ouedraogo, (Burkina Faso)]. / Aspects épiémiologiques et cliniques des extractions dentaires au Centre Hospitalier Universitaire Yalgado Ouedraogo (Burkina Faso).

INTRODUCTION: The consequences of tooth loss are often severe for the patient: aesthetic deficit, decreased masticatory coefficient, malnutrition... The objective of this study was to describe the epidemiological and clinical aspects of dental extractions of patients attending the University Teaching Hospital Yalgado Ouedraogo (UTHYO). PATIENTS AND METHODS: It was a descriptive cross-sectional retrospective study on a sample of 65 patients who received a dental extraction at least in dental surgery of the UTHYO. RESULTS: The sample consisted of 33 (50.8%) patients female to 32 (49.2%) cases of male, or a sex ratio of 0.96. The average age was 36,55 year-old with extremes of 5 and 84 years. Employees and pupils were the most affected by extractions (33 cases; 47,8% and 22 cases; 33,8%). Dental extractions were more frequent in patients aged between 25 and 60 years. A total of 84 tooth extraction was performed in 65 patients, an average of 1.3 tooth extracted per patient. The most often extracted tooth was the third lower molar (17 cases, 22,95%). The canine was the less often extracted tooth (1 case, 1,35%). Dental decay and its complications (57 cases, 67,87%) and periodontal diseases (10 cases, 11,90%) were the commonest reasons for dental extractions. CONCLUSION: Dental decay and periodontal diseases are the most important causes of dental extractions. Particular emphasis should be placed on prevention and early care of teeth.

[HIV and noma in Burkina Faso]. / VIH et noma au Burkina Faso.

INTRODUCTION: Noma is a "gangrenous" disease beginning in gums and spreading to other parts of the face. It usually occurs in undernourished children with bad orodental hygiene. Its incidence in adults is increasing. HIV infection is very common in African countries. We had for objective to compare noma characteristics in patients with, or without, HIV. MATERIAL AND METHODS: This retrospective and descriptive study included patients managed for noma in our unit from January 1988 to December 2007. The clinical, epidemiological, and outcome data of patients treated for noma were compared according to HIV infection status. RESULTS: Two hundred and twelve patients were included and 14 (6.6%) among them were HIV positive. In the HIV positive group, there were a male predominance and patients were older (mean age 15.3 vs. 4.7 years in the other group). HIV positive patients were less frequently operated (35.7% vs. 76.3%) and their death rate was higher (37.5% vs. 5.6%). DISCUSSION: HIV infection during the course of noma impacts the clinical and epidemiological features of this condition. It worsens the prognosis. Noma could be considered as an opportunistic infection in the WHO disease staging system.

Plasmodium falciparum sexual conversion rates can be affected by artemisinin-based treatment in naturally infected malaria patients.

BACKGROUND: Artemisinins (ART) are the key component of the frontline antimalarial treatment, but their impact on Plasmodium falciparum sexual conversion rates in natural malaria infections remains unknown. This is an important knowledge gap because sexual conversion rates determine the relative parasite investment between maintaining infection in the same human host and transmission to mosquitoes. METHODS: The primary outcome of this study was to assess the impact of ART-based treatment on sexual conversion rates by comparing the relative transcript levels of pfap2-g and other sexual ring biomarkers (SRBs) before and after treatment. We analysed samples from previously existing cohorts in Vietnam, Burkina Faso and Mozambique (in total, n=109) collected before treatment and at 12 h intervals after treatment. As a secondary objective, we investigated factors that may influence the effect of treatment on sexual conversion rates. FINDINGS: In the majority of infections from the African cohorts, but not from Vietnam, we observed increased expression of pfap2-g and other SRBs after treatment. Estimated parasite age at the time of treatment was negatively correlated with the increase in pfap2-g transcript levels, suggesting that younger parasites are less susceptible to stimulation of sexual conversion. INTERPRETATION: We observed enhanced expression of SRBs after ART-based treatment in many patients, which suggests that in natural malaria infections sexual conversion rates can be altered by treatment. ART-based treatment reduces the potential of a treated individual to transmit the disease, but we hypothesise that under some circumstances this reduction may be attenuated by ART-enhanced sexual conversion.

[Metabolic disorders and cardiovascular risk factors observed in patients infected by the HIV with antiretroviral therapy in Burkina Faso]. / Troubles métaboliques et facteurs de risques cardiovasculaires chez les patients infectés par le VIH sous antirétroviraux au Burkina-Faso.

The purpose of this descriptive transverse study is to describe metabolic disorders and cardiovascular risk factors in HIV-infected patients undergoing antiretroviral therapy in the day-care unit of the University Hospital of Ouagadougou, Burkina-Faso. A total of 100 patients (Burkinavi cohort) undergoing antiretroviral therapy with a minimum of 42-months of follow-up (October 2005 to Mars 2009) were included. There were 77 females and 33 males with a mean age of 37 years. Most patients, i.e., 95%, were positive for HIV1. Mean body mass index was 22 kg/m2. Mean CD4 count was 280/mm3. Viral load was undetectable in 66 of the 71 patients who underwent viral load testing. Retroviral therapy consisted of the TriomuneR combination (Stavudine + lamivudine + névirapine) at a fixed dose in 27 cases. Cardiovascular risk factors included family history of high arterial blood pressure in 5 patients, smoking in 4, and obesity in 8. During follow-up, seven patients presented hypertension. Metabolic disorders included hyperglycemia (4%), hypertriglyceridemia (17%) and hypercholesterolemia (14%). Lipodystrophia was noted for 6 patients. Despite the short follow-up period, metabolic disorders and cardiovascular risk factors were observed at our patients under antiretroviral therapy.

[Prevalence and risk factors associated with infection by human immunodeficiency virus, hepatitis B virus, syphilis and bacillary pulmonary tuberculosis in prisons in Burkina Faso]. / Prévalences et facteurs associés aux infections a Virus de l'Immunodéficience Humaine et virus de l'épatite B, a la syphilis et a la tuberculose pulmonaire bacillifère en milieu carcéral au Burkina Faso.

This purpose of this study was to determine prevalences and risk factors associated with infection by human immunodeficiency virus, hepatitis B Virus, syphilis and bacillary pulmonary tuberculosis in prisons in Burkina Faso. From February 20 to March 20, 2009, 300 prisoners over 18 years of age held in Ouagadougou were selected to take part in this descriptive and analytical cross-sectional study. Sociodemographic data, confinement information (number, motive and prison time), medical history, substance addiction (alcohol, tobacco, drug), and the other risk behaviors (sexual relations, type of partners, sharing of toiletries or razor) were compiled for each prisoner. Serological tests were performed to detect anti-HIV antibodies, Hbs antigen, and anti-treponema antibody. In prisoners presenting signs of tuberculosis, BAAR detection was performed by direct examination of sputum. Men represented 95% of the study population. Median age was of 30.1 +/- 8.9 years (range, 18 and 63). The prevalences of HIV infection, Hbs antigen and positive syphilitic serology were 5%, 27.3% and 5.7% respectively. Four prisoners (1.3%) had bacillary pulmonary tuberculosis. Two prisoners reported homosexual intercourse and 44 reported drug abuse. Sharing of toiletries and razor blades was reported by 18.7% and 20% of the prisoners respectively. Immediate measures are needed reduce the spread of these infections in prisons in Africa.

[Prevalence of Diabetes and Diabetes-Related Cardiovascular Risk Factors in a Rural Population in Burkina Faso]. / Prévalence du Diabète et Facteurs de Risque Cardiovasculaire Associés dans une Population Rurale au Burkina Faso.

Objective: Rural areas are currently facing lifestyle changes which greatly contribute to an increase in the prevalence of diabetes and cardiovascular diseases. The aim of this study was to estimate the prevalence of Diabetes and Diabetes-related cardiovascular diseases in a rural population in Burkina Faso. Methodology: We collected demographic and clinical data, and we also performed capillary glucose testing for all the participants aged 16 years and above in five administrative communities in the province of Zandoma. Results: In all, 970 individuals, with a mean age of 49.06 years (SD = 16.97), volunteered to participate in the screening. Most of them were aged between 40 and 65 years old (48.5%) and 57.5% were females. The prevalence of diabetes was 5.7%, and 9% of participants had an FPG level between 1.10 g/l and 1.26 g/l. A family history of diabetes was found in 4.3% of the cases. Looking at the other cardiovascular risk factors, we found 24.3% of the participant to be overweight or obese, 23.6% had High Blood Pressure. Age (p = 0.001), Employment Status (p = 0.015), Body Mass Index (p = 0.036) were significantly associated with diabetes. Conclusion: Diabetes is prevalent in rural areas in Burkina Faso, along with a significant proportion of prediabetes cases. Age, Employment Status, and BMI are the principal associated factors.

[Rheumatologic diseases and haemoglobinopathies in Ouagadougou (Burkina Faso)]. / Pathologies rhumatologiques et hémoglobinopathies à Ouagadougou (Burkina Faso).

The purpose of this study is the prevalence of the rheumatologic complications in the sickle cell disease and the associations between haemoglobinopathies and rheumatologic affections. It is a retrospective study from 29 February 2006 to 28 March 2008 conducted in the Internal Department of the University Hospital Yalgado-Ouédraogo. All patients received in the period of study and having an electrophoresis of haemoglobin realized in alkaline pH were included. These patients came from hematologic consultation. Two hundred and seventy-seven patients out of 1451 were included: 142 patients (51.30%) had haemoglobinopathies, including 21 (7.60%) with composite sickle cell disease SC and 17 patients (6.13%) had aseptic necrosis of the femoral head including 7 with haemoglobin SC. The other rheumatologic affections did not have a semiological particularity related to the type of haemoglobin. The prevalence of patients who have haemoglobinopathies is important in rheumatologic practice. The sickle cell disease is strongly associated to osteonecrosis.

[Prevalence and factors associated with low back pain among hospital staff in Ouagadougou (Burkina Faso)]. / Prévalence et facteurs de risque associés à la lombalgie chez le personnel hospitalier à Ouagadougou (Burkina Faso).

OBJECTIVE: The aim of our study was to determine the prevalence, risk factors, associated with low back pain among hospital staff in a developing country. PATIENTS AND METHODS: This transversal study was conducted from March 2007 to February 2008 at Yalgado Ouédraogo Teaching Hospital in Ouagadougou (CHU-YO), Burkina Faso. RESULTS: There were 256 men and 180 women with an average age of 38 +/- 8.25 years (range, 22 to 58). Mean BMI was 25.11 +/- 4.03 Kg/m2. The prevalence of chronic low back pain was 56.4% overall, 47.3% in men and 69.4% in women. Individual risk factors included female sex (p=0.000004), age (p=0.026), and high BMI (p=0.0002). Sports activity appeared to be a protective factor (p=0,035). Professional risk factors were the number of working hours per week (p=0,005) and numbers of guards per month (p=0.014) and posture during work (p=0.01). Analysis of socioprofessional consequences revealed significant impact in 43 (17,5%) patients. The loss work hours in 2007 were estimated to 1020. Three patients had to change working stations due to disability and 82 (19%) reported restricted working capacity. CONCLUSION: The prevalence of low back pain is high among hospital staff of CHU-YO. Preventive measures are needed to reduce socioprofessional consequences.

[Rheumatic disorders observed in HIV infected patients undergoing highly active antiretroviral therapy (HAART): a 366 case prospective study in Burkina Faso]. / Manifestations rhumatologiques des personnes vivant avec le virus de l'immunodéficience humaine, traitées par antirétroviraux: etude prospective de 366 malades au Burkina Faso.

OBJECTIVE: The purpose of this report is to describe epidemiological aspects of rheumatic disorders observed in HIV-infected patients undergoing highly active antiretroviral therapy (HAART). Patients and methods. This cross-sectional study was conducted from January 1 to June 30, 2008 in the HIV unit of an internal medicine department in Burkina Faso. All patients who had been undergoing HAART for at least one year were included. Interviewing and thorough physical examination were performed in all cases. Radiography of the pelvis and hip was performed in some patients. Bone densitometry was never performed. RESULTS: A total of 366 patients including 265 women and 101 men (sex ratio of 0.38) were included. Mean patient age was 39.61 +/- 8.54 years. Three hundred and thirty-five patients (91.53%) were positive for HIV1, 17 (4.64%) for HIV2 and 14 (3.83%) for both HIV1 and HIV2. Mean duration of infection was 3.58 +/- 1.88 years. Mean CD4 cell count was 394.20 cell/microL. A recent HIV viral load determination was available for 285 patients including 262 who had no detectable virus. Mean duration of HAART was 35.80 +/- 15.17 months. Only 61 patients (16.66%) were treated with protease inhibitor (PI). The prevalence of rheumatic disorders was 5.73% (21 cases). A variety of disorders were observed, i.e., lower back pain in 8 patients (38.1%), arthralgia in 4 patients including 2 treated with PI, osteoarthritis of the knee in 2 patients, Pott disease in 2 patients, De Quervain disease in 2 patients including one treated with PI, tendinitis of the shoulder in one patient treated with PI, gout in one patient treated with PI and unclassifiable inflammatory rheumatism in one patient. No case of symptomatic osteonecrosis or osteoporosis was observed. CONCLUSION: Rheumatic disorders are uncommon in the HIV-infected patients undergoing HAART in Burkina Faso. The most likely explanation is that PI is not widely used.

[Arthropathic and degenerative pathology in rheumatology patients in Burkina Faso]. / Pathologie mécanique et dégénérative en consultation de rhumatologie au Burkina Faso.

OBJECTIVE: The purpose of this report is to describe epidemiologic features of arthrosic and degenerative disorders observed during the first two years of rheumatologic practice in Ouagadougou, Burkina Faso. PATIENTS AND METHODS: The files of all patients examined between March 2006 to February 2008 were reviewed. All patients presenting arthrosic or degenerative disorders were included. RESULTS: Out of 1,439 patients examined during the study period, 1,078 (74.91%) were included. Spine pain accounted for 33.7% of cases, i.e., 485 patients including 306 with lumbago. The mean age in this group was 47.8 +/- 15.19 years and the M/F sex ratio was 0,75. Osteoarthritis represented 20.43% of cases including osteoarthritis of the knee in 18%. The mean age in this group was 54.66 +/- 12.29 years and the M/F sex ratio was 0.23. Aseptic osteonecrosis (AON) of the femoral head was observed in 1.11% of cases, i.e. 16 patients including 8 with sickle cell disease (SC) The mean age in this group was 40.75 years. Abarticular rheumatism accounted for 15.98% of cases, i.e. 230 patients including 118 cases with tendinitis of the shoulder. The mean age in this group was 48.48 years. CONCLUSION: Arthrosic and degenerative disorders observed in this series from Ouagadougou presented the same semiological features as in other African series. Primary osteoarthritis of the hip was uncommon.

[Wallenberg syndrome and neurocysticercosis: about one case in Ouagadougou, Burkina Faso]. / Syndrome de Wallenberg et neurocysticercose: a propos d'un cas a Ouagadougou, Burkina Faso.

Neurocysticercosis (NCC) frequently appears by seizures following parenchymatous location of encysted worms of Taenia solium. We report a case of NCC revealed by a Wallenberg's syndrome. A man of 44 years old, without any cardiovascular risk factor was admitted at the neurology department of Yalgado-Ouédraogo hospital in Ouagadougou for an abrupt onset of vertigos, recurrent falls on the right side, hiccough, and deglutition weakness. The clinical examination found a blood pressure at 130 mmHg/80 mmHg, a CMI at 24, a Wallenberg's syndrome. The CT scan showed a laterobulbar lacunar infarct with punctiform calcifications of cerebellum, third ventricle, frontal, right temporal, occipital and left parietal lobes. The CSF showed a raise of cells number at 23 lymphocytic elements, proteins rose to 1.5 g/l, glucose and chloride were normal. Cysticercosis blood and CSF serologies were positive. The blood cells count showed only an eosinophilia and the blood sedimentation rate reached 119 mm in the first hour. The accepted diagnosis was: laterobulbar lacunar infarct following a NCC angiitis. The course of the disease under albendazole at 15 mg/kg during two weeks combined with a short steroid therapy by prednisolone at 1 mg/kg during 5 days was favourable. NCC should be more and more regarded as a cerebrovascular risk factor in endemic area, especially in young people.

[Main characteristics of the street food sector in Bobo-Dioulasso, Burkina Faso]. / Caractéistiques de l'alimentation de rue dans la ville de Bobo-Dioulasso, Burkina Faso.

To investigate the sector of food sold in the streets of Bobo-Dioulasso and identify relevant information for action, a survey on knowledge and practices of street food vendors and consumers was conducted in June 2005. Data have been collected in 928 street food selling posts. Structured questionnaires were used to collect data from 874 street vendors and 2474 consumers. Street food sites are concentrated in places where administration and trade activities are usually running. The street food seller is a married and illiterate woman of 32 years old. Cereals (48.5%), meat (33.9%), milk (9.6%) and fruits (4.4%) are the basic consumables. The street food consumer is a non married man, 27 years old working in profit-making activity. Consumers use many criteria to choose the place to eat, at times or permanently. The street food sector represents a source of income and induces change in household eating habits. Street food in Bobo-Dioulasso needs to be better organised, by using an holistic approach that involves all the actors.

[Conidiobolomycosis, a rare fungal tumor: a case report in Ouagadougou, Burkina Faso]. / Conidiobolomycose, une tumeur fongique rare: un cas a Ouagadougou, Burkina Faso.

Conidiobolomycosis is a deep, rare mycosis, due to Conidiobolus coronatus which is a saprophyte of vegetation in decomposition. We report one case in Burkina Faso. A 17 years old man, shepherd, consulted for tumefactions on the face. It could date back insidiously to a traumatism, one year before. A month later some painless tumefactions appeared on the cheekbone, the right eyelid, the nose with epistaxis. The upper lip then the lower one had swollen. Dermatological exam revealed multiple, painless, hard, sub-cutaneous swellings, affecting the cheekbone, the eyelids, the root and the ala of the nose. This tumefaction sometimes adhered to underlying tissues and to the overlying skin, sometimes mobile; painless and hard swelling of the two lips was also noted. ENT exam showed an inflammation of the nasal mucous without ulceration and the permeability of the nasal tracts was subnormal. The cephalic tomodensitometry showed a thickness of the soft tissues of the lips and the nose with an infectious feature associated to a pansinusitis without bone lesion. Histology was in favour of conidiobolomycosis. The patient was treated with fluconazole and the swelling progressively disappeared. Conidiobolomycosis is a disease generally reported in some humid tropical countries. It begins in the nasal cavities leading then to a nasal obstruction. This case was singular by the fact it happened in a dry Sudano-Sahelian climate and by its clinical features.

[Risk factors associated with osteoarthritis of the knee in a rheumatology outpatient clinic in Ouagadougou, Burkina Faso]. / Facteurs de risque associés à la gonarthrose en consultation de rhumatologie à Ouagadougou (Burkina Faso).

The purpose of this transverse prospective study was to assess risk factors associated with osteoarthritis (OA) of the knee observed in a rheumatology outpatient clinic in Ouagadougou, Burkina Faso. All patients presenting osteoarthritis of the knee diagnosed according to the clinical and radiological criteria of the American College of Rheumatology (ACR) were recruited over a 9-month period from November 2006 to July 2007. A total of 118 patients including 108 women were studied. Mean patient age was 55.7 +/- 10.8 years. Pain and disability scores assessed using theLequesne index were greater than 8 in 87.3% of patients. Hydarthrosis was observed in 56.5% of patients. The most common associated risk factors for development of osteoarthritis of the knee were obesity (42.4%), menopause in women (66.7%), history of OA (43.2%), and previous knee injury (19.5%). The most common associated risk factors for progression of osteoarthritis of the knee were Heberden nodes (19.5%) and genu varum (52.5%). The risk factors for development and progression of osteoarthritis of the knee in the subsahalian population of Ouagadougou are the same as in the Caucasian population of industrialized countries. An unexpected finding in this black African population was the high prevalence of Heberden nodes.

[Lumbar nerve root pain with fever in tropical area: posterior spinal tuberculosis]. / Lomboradiculalgies fébriles en zone tropicale: atteinte tuberculeuse de l'arc vertébral postérieur.

The purpose of this report is to describe the case of tuberculosis osteitis of the posterior vertebral arch in a 35-year-old man with recent history of pulmonary tuberculosis. Clinical findings were pain due to bilateral inflammation of the lumbar nerve roots, fistulised cold abcess and motor deficit in both lower extremities. The tomodensitometry demonstrated a lytic bone lesion involving the spinous process of the second lumbar vertebra in association with spondylitis and a large paravertebral abscess with calcification typical of tuberculosis. Cure was achieved by a single 12-month course of appropriate treatment.

[Chronic osteomyelitis at the Ouagadougou teaching hospital (Burkina Faso). A retrospective study of 102 cases (1996-2000)]. / Ostéomyélites chroniques au CHU de Ouagadou- gou (Burkina Faso). Etude rétrospective de 102 cas (1996-2000).

This is a retrospective study carried out in the orthopaedic and trauma department of the Yalgado-Ouédraogo teaching hospital. All the patients hospitalized in the service with a chronic osteomyelitis (COM) from March 1, 1996 to March 28, 2000 were included. The frequency of COM was 5.3%. The patients' average age was 17.7 with extremes of 2 and 60 years old. 63.9% were male; 80.7% had fistulized COM. A pathological fracture was observed in 16.9% of the patients. Lower limbs were affected most frequently (65%). Thirty patients (36.1%) had haemoglobin S, among them 22 had a major sickle cell disease. Staphylococcus aureus was present in the majority of the cases (more than 50%). Salmonella were observed among patients carrying haemoglobin S. One case of ceftriaxone-resistance salmonella osteomyelitis was reported. The medico-surgical and orthopaedic treatment was statistically more favourable than a medical or medico-surgical treatment without immobilization.
