[Evaluation of the risk of obstructive sleep apnea in patients awaiting general anesthesia in Burkina Faso]. / Évaluation du risque du syndrome d'apnées hypopnées obstructives du sommeil chez des patients en attente d'une anesthésie générale au Burkina Faso.

INTRODUCTION: General anaesthesia and surgery increase morbidity and mortality in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) who are not known to have OSAHS and therefore not treated before surgery. The objective of this study is to evaluate the risk of OSAHS using the STOP-BANG questionnaire (SBQ) in patients undergoing general anaesthesia in Burkina Faso. MATERIAL AND METHOD: This is a cross-sectional study concerning patients having received pre-anaesthetic consultation from 1st July 2020 to 30th June 2021. Risk of OSAHS is considered "medium to high" when the risk of obstructive sleep apnea is medium or high on SBQ. RESULTS: Our population consisted in 599 persons. A medium to high risk of OSAHS was found in 11.18%. The ASA score and the Mallampati scale were independently associated with moderate to high risk of OSAHS (P<0.001; P<0.001). ASA score of I and Mallampati class of I decreased the risk of OSAHS by 17 and 45% respectively (P=0.012; P=0.031). CONCLUSION: The risk of OSAHS in this population is comparable to that of the general population. Confirmation of OSAHS by ventilatory polygraphy or polysomnography would help to achieve further precision.

Knowledge, practices and beliefs of students regarding health effects of shisha use in Ouagadougou, Burkina Faso: A cross­sectional study.

Background: The tobacco epidemic is one of the biggest public health threats the world has ever faced. Shisha use has recently been gaining increased popularity in many developed and developing countries. Objectives: To determine the prevalence of shisha use among students in Ouagadougou, Burkina Faso, and associated knowledge, smoking practices and beliefs about health effects. Methods: A total of 443 students were selected for this cross-sectional study, using a stratified sampling method. Data on shisha use, knowledge about shisha, shisha smoking practices, and factors associated with use of shisha were collected via a questionnaire. The association between the independent variables and shisha use was assessed using a χ² test (p<0.05). Binary logistic regression analysis was used to determine variables that were independently associated with shisha smoking. Results: Of the 421 respondents, 162 (38.5%) indicated that they had smoked shisha; 14.0% were regular smokers. We found that 183 students (43.5%) had poor knowledge about the health effects of shisha. The main reasons for shisha smoking were being in the company of friends who were users (57.4%), the pleasant flavour and fragrance of shisha (25.9%), and fashion (22.2%). Ninety-nine shisha smokers (61.1%) also consumed alcohol. Factors associated with shisha smoking included age <20 years (p<0.001), gender (p=0.034), and educational level of the respondent's father (p=0.0001) and mother (p=0.0004). Conclusion: We found a relatively high prevalence of shisha smoking among the students, and that 43.5% of them had poor knowledge about its effects on health. Developing surveillance, intervention and regulatory/policy frameworks specific to shisha has become a public health priority. Study synopsis: What the study adds. The study provides additional data from resource-poor settings such as Burkia Faso, where there is an overall high prevalence of Sisha smoking, and also among students who are poorly informed about the health effects of smoking. Implications of the findings. The data informs advocacy and intervention strategies to combat smoking and decrease overall tobacco use in an African setting.

[A case of malformation of aortic arches simulating asthma]. / Un cas de malformation des arcs aortiques simulant un asthme.

INTRODUCTION: Abnomalies of the aortic arches are rare and account for 1% of congenital cardiovascular malformations. They constitute one of the causes of compression of the airways with attacks of dyspnea sometimes simulating an asthma. We report the case of an infant with an anomaly development of aortic arches with impact breathing. CASE REPORT: It was a 22-month-old infant who consulted for a dyspnea with a type of stridor associated with a fat cough. This clinical table started 45 days after its birth and led to many hospitalizations in the pediatric emergency. Clinical exam found polypnea, with a wheezing, bronchial groan and diffuse sibilants on the auscultation. The chest X-ray revealed a slightly retractile right lung. The angioscanner of the thoracic and abdominal aorta showed a double aortic arch with retro-oesophageal left ventricular artery. A thoracotomy was performed and the operative sequences were simple. CONCLUSION: The congenital anomalies of the aortic arch are rare and varied, sometimes asymptomatic. This case reminds us that, in front of any recurrent or digestive respiratory signs in the infant, malformation of the aortic arches should be considered.

[Survival of malignant and paramalignant pleural effusions in Ouagadougou]. / Survie des pleurésies malignes et paramalignes à Ouagadougou.

This study aimed to present the survival of patients with malignant and paramalignant pleural effusion (MPE) in a context of resource-limited countries. We retrospectively studied patients received for malignant and paramalignant pleural effusion in three health facilities in Ouagadougou from 1st August 2009 to 30 July 2015. Survival was analyzed according to various characteristics related to patients and disease. Eighty patients with a mean age of 54 years were selected. The sex-ratio was 0.9. Sixteen patients had comorbidities. Pleural effusion was revealing, synchronous and metachronous in respectively 55 %, 26.3 % and 17.5 % of cases. Lung cancer was the most common cause of MPE (27.5 %), followed by breast cancer (18.7 %). The median overall survival was 3 months; it varied between primary cancers: 5 months for primary cancer unknown, 4 months for lung cancers and 2 months for breast cancers. Sex and the presence of comorbidities were independent factors influencing survival of patients. In this study, patient survival length is strongly compromised by inadequacies of medical technical equipment.

[Epidemio-clinical aspects of adult acute bacterial pneumonia at Yalgado Ouédraogo University Health Center]. / Aspects Epidemio-cliniques des Pneumopathies Aiguës Bacteriennes de L'Adulte au Chu Yalgado Ouedraogo.

INTRODUCTION: Bacterial Pneumopathies are low respiratory infections due to parenchyma pulmonary attack, which etiologic agent is a bacteria different from tubercular bacillus. Factually, the treatment is based on a probalistic antibiotherapy. This requires awareness of the epidemiology of the germs which are responsible in a given region, at a given period. PATIENTS AND METHOD: In order to better grasp mainly the bacteriological and therapeutic aspects of adult bacterial Pneumopathies in Burkina Faso, we have come up with a two year journal/documentary. RESULTS: The reported most frequent germs are respectively: Streptococcus pneumoniae (32,6%), Klebsiella pneumoniae (21%) et Staphylococcus aureus (13,9%). Negative Gram bacteries represented 53.5% of isolated germ and Acinetobacter was found only with HIV positive patients. The streptococcus was sensitive to association amoxicilline + clavulanic in 91.7% of the cases, to ceftriaxone in 83.3% of cases, to ampicilline and to amoxicilline in 66.7% of cases The clinical evolution of our patients was favorable in 74.5% of the cases with 21.8% deaths. The evolution was more significant within alcoholic patients (p = 0.001) as well as tobacco addicted patients (p = 0.02). CONCLUSION: The high morbi-morbidity due to acute pneumopathy could be improved through a better awareness and regular updating of local bacterial ecology.

[Bronchopulmonary Kaposi's disease in 2 AIDS patients living in a zone of high tuberculosis/HIV prevalence]. / Kaposi broncho-pulmonaire au cours du SIDA en zone de forte prévalence tuberculeuse/VIH. A propos de deux cas.

The epidemic form of Kaposi's disease, called Kaposi-AIDS, was first described in 1981 by Hymmes in two young AIDS patients. Lung lesions are observed in 10 to 45% of patients with cutaneous Kaposi and are the second leading localization of visceral involvement after the digestive tract. Diagnosis and management of these visceral forms remains difficult. We report two cases of broncho-pulmonary Kaposi-AIDS in two patients treated for cutaneous Kaposi's disease. The diagnosis was made on the basis of epidemiological, clinical, biological, radiological, endoscopic, and histological evidence. The diagnosis was achieved by elimination after ruling out all other opportunistic diseases with pulmonary tropism. The fear of miliary tuberculosis remains strong in zones with a high prevalence of tuberculosis. Despite considerable improvement with antiretroviral drugs, especially antiproteases, outcome remains unpredictable with or without specific treatment.

[Contribution of bronchial fibroscopy in pneumonology services in developing countries]. / Apport de l'endoscopie bronchique dans un service de pneumologie d'un pays en développement.

Bronchial fibroscopy is a recent investigation method that requires equipment and facilities difficult to implement in respiratory diseases units in developing countries. In Burkina Faso, this technique was introduced for the first time in February 1997. The purpose of this study was to determine the contribution of bronchial fibroscopy for the diagnosis of respiratory disease in countries with limited resources. This study was conducted between February 1997 and October 1998 at the respiratory diseases unit of the Yalgado Ouedraogo National Hospital Center in Ouagadougou, Burkina Faso. Thirty-five cases of tuberculosis were diagnosed, including 29 cases with bronchial node involvement, where bronchial fibroscopy is an essential diagnostic examination, and 6 cases of bacteriologically proven pulmonary tuberculosis. Ten cases of lung cancer were diagnosed (40% squamous cell carcinoma). Malignant disease is a reality in developing countries despite low rates of diagnosis due to insufficient diagnostic facilities. For tuberculosis, the importance of specific treatment is certainly well established and should always be initiated, even if fibroscopy cannot be performed. This contrasts with the situation for malignant disease, where the high prevalence of lung cancer (9.9% of the bronchial fibroscopies performed) is associated with total lack of treatment due to the absence of a thoracic surgery unit or a radiotherapy unit, and the impossibility of providing satisfactory surveillance of anti-cancer chemotherapy.

[Primary pulmonary myxoid liposarcoma discovered fortuitously]. / Liposarcome myxoïde pulmonaire primitif de découverte fortuite.

We report a fortuitous discovery of primary pulmonary myxoid liposarcoma in an HIV-positive patient. Primary pulmonary localizations are uncommon. Generally, pulmonary localizations are metastatic. There is a male predominance and diagnosis is generally made around 40 years of age. The two main features of liposarcoma are the large tumor size and the complex histology that evolves over time. Pathology findings are rarely reproducible and vary from one pathologist to another. Macroscopically, liposarcomas can mimic benign tumors. The risk of recurrence is high after simple enucleation due to microscopic extracapsular extensions. Surgery remains the predominant treatment. Wide complete excision, if possible, provides long-term survival.

[Active tuberculosis in a patient with Hodgkin's disease. A case report]. / Tuberculose évolutive associée à une maladie de Hodgkin. A propos d'un cas.

We report a case of active tuberculosis in a patient with Hodgkin's disease. The two diagnoses were established simultaneously at the Respiratory Disease Unit of the Yalgado National Hospital, Burkina Faso. The clinical presentation was misleading as the signs and symptoms of the two disease are similar. Certain diagnosis was established after isolation of tuberculosis bacilli and histocytology findings for Hodgkin's disease. Both diseases are potentially curable. The clinical course depends on early diagnosis and treatment.
