Introduction: Violence is a major problem in today’s workplace. It affects workers in all sectors of activity. The aim of the study was to determine the prevalence and factors associated with violence among primary and secondary school staff in ouagadougou. Materials and Methods: This was a cross-sectional, descriptive and analytical study that took place from April 22, 2020 to February 18, 2021 in primary and secondary schools in ouagadougou. It focused on the educational staff of these establishments. Results: A total of 362 agents took part in the study. The average age of participants was 36.5 ± 6.89 years. The sex ratio was 1.62 men to one woman. The majority of workers were teachers, with 300 participants (82.87%). The average job tenure was 7 years ± 6.91 years. With regard to violence in the workplace, 87 workers were victims, representing a prevalence of 24.03%. Of these workers, 59 (67.81%) were men and 36 (41.38%) had less than six years’ experience. Acts of violence were predominantly pushing observed in 15 workers (50%), while shouting and aggressive tone dominated psychological violence and concerned 54 cases (36.24%). On univariate analysis, the factors associated with violence were age (p = 0.046) and type of establishment (p = 0.012). On multivariate analysis, only the nature of the establishment was the only factor associated with the occurrence of violence among teaching staff (OR = 2.3690, p = 0.0213). Conclusion: The prevalence of violence is high in these educational establishments. Age and type of establishment are factors associated with its occurrence. It is therefore necessary to develop an effective strategy for preventing this risk in the workplace.

Open Journal of Obstetrics and Gynecology 2024年第9期14卷 1407-1413页

作者： Yobi Alexis Sawadogo Emmanuel ouédraogo adama ouattara Issa ouédraogo Sibraogo Kiemtoré Charlemagne ouedraogo Department of Obstetrics and Gynaecology Bogodogo University Hospital Ouagadougou Burkina Faso Health Science Training and Research Unit Joseph Ki-Zerbo University Ouagadougou Burkina Faso Department of Obstetrics and Gynaecology Ouahigouya Regional University Hospital Ouahigouya Burkina Faso Department of Obstetrics and Gynaecology Yalgado Oudraogo University Hospital Ouagadougou Burkina Faso

Splenic injury caused by abdominal trauma during pregnancy is rare. Splenic injury associated with fetal death in utero following a fall from a tree top is even rarer. The authors report a case of splenic trauma associated with fetal death in utero following a fall from the top of a tree in a 19-year-old pregnant woman at 30 weeks amenorrhoea. She was referred from a 1st level health facility for trauma that had occurred the day before admission. She was in poor general condition (WHO performance status IV) and had a cardiovascular collapse. Ultrasound was used to diagnose haemoperitoneum and fetal death in utero. A CT scan was used to diagnose splenic lesions. Treatment consisted of splenectomy and caesarean section after resuscitation.

Smart Grid and Renewable Energy 2024年第6期15卷 139-148页

作者： Prince Abdoul Aziz Honadia Bernard Zouma adama ouédraogo Fabé Idrissa Barro Department of Physics and Chemistry Centre Universitaire de Kaya (CU-K) Kaya Burkina Faso Thermal Renewable Energies Laboratory Department of Physics Joseph Ki-Zerbo University Ouagadougou Burkina Faso Semiconductors and Solar Energy Laboratory Department of Physics Faculty of Science and Technique Cheikh Anta Diop University Dakar Senegal

The quadratic boost is studied under its real model. The equations, of the continuous conduction mode, descriptive of this model are established. From these equations, the expressions of the voltage gain and the efficiency are extracted. These two quantities are plotted as a function of the duty cycle in order to appreciate them in different operating points of the transistor. The values of the different components have also been extracted for the fabrication of a prototype of the converter. Thanks to a set of experimental measurements at the input as well as at the output of the prototype converter, the voltage gain and the efficiency could also be observed. These were also plotted for different loads to observe converter behavior. The theoretical curves were compared with the experimental curves which allowed to validate the proposed mathematical models on a large range of duty cycles.

Primary Total Hip Arthroplasty on Complex Hips Conditions in a Low-Resource Setting

引用

Open Journal of Orthopedics 2024年第7期14卷 325-333页

作者： Souleymane ouédraogo Malick Diallo Sékou Sidibé Massadiami Soulama adama Sidibé ousmane ouermi Patrick W. H. Dakouré Orthopedics and Traumatology Department University Hospital Sour SANOU Bobo-Dioulasso Burkina Faso Superior Institute of Medical Sciences University Nazi BONI Bobo-Dioulasso Burkina Faso

Introduction: Total hip arthroplasty of complex morphology is a challenge for the orthopaedic surgeon. Careful analysis of the hip’s anatomy helps to unravel the difficulties and anticipate the procedures to be performed and the implants to be planned. The aim was to identify the types of hip that make first-line THR difficult, specify the technical procedures to be used on these sites, and assess the functional results of the series. Material and Methods: This was a retrospective study that concerned patients operated on for total hip arthroplasty between January 2015 and December 2022 at the medical center “La Grâce” in Bobo-Dioulasso, Burkina Faso. Patients with coxarthrosis (on hip dysplasia, acetabular protrusio, acetabular malunion or neurological hip) and those with ankylosis of the hip, osteonecrosis secondary to neglected dislocation of the hip or hemoglobinopathy were included. Results: A total of 31 total hip replacements were performed in 30 patients. The mean age of patients at the surgery time was 36.2 years with extremes of 17 and 61 years. The male-to-female sex ratio was 1. The main indications for THA were the dysplasic hip osteoarthritis (11 cases) and the neglected hip dislocations (7 cases). In situ femoral neck osteotomy before hip dislocation was performed in seven cases. The acetabulum reconstruction techniques varied from the structural iliac bone graft (n = 3) and cancellous bone graft (n = 4) to the Kerboull plate (n = 1). After 45 months of mean follow-up, all hips were evaluated. The mean PMA score increased from 7.1 [4 - 8] before the surgery to 13.2 [13 - 17]. Conclusion: The large spectrum of challenges in complex hip management requires effective preoperative planning. Preoperative planning minimizes complications and ensures a better outcome.

The Pouni area is made up of basalts belonging to the Boromo belt, lamprophyres and granitoids. These geological formations are similar to geological formations of the same type in other regions of the Palaeoproterozoic domain of the Man/Leo shield. This study, which focused on the petrographic and geochemical characteristics of these geological formations, led to the following main conclusions: The lamprophyres are basic plutonic rocks that cut through other geological formations. The basalt belongs to the northern part of the Borormo belt and is thought to be a relic of overthickened oceanic plateaus. There are two groups of granitoid rocks. The granodiorite has a geochemical signature close to that of Archean TTGs and is metaluminous in character. It has a low potassium content. The minor element and rare earth element spectra indicate that it could be derived from partial melting of basic magmatic rocks. Biotite granites are peraluminous and highly potassic. Minor element contents and rare earth spectra indicate that they could be derived from partial melting of felsic materials. Geotectonic diagrams show that the granitoids identified in the Pouni zone were emplaced in an active tectonic context, similar to that of present-day subduction zones.

South of Godé, in the central-western region of Burkina Faso, granitoids of Paleoproterozoic age are similar to those of the Man/Leo shield. This study focused on the petrographic and geochemical characteristics of these granitoids, with the following results: 1) The tonalite that outcrops in the south-west of the study area belongs to the TTG group or first generation granitoids. They are most often ribboned at outcrop and have a geochemical signature close to that of Archean TTGs. Tonalite has a metaluminous character and the REE spectrum indicates that it may be derived from partial melting of basic magmatic rocks. 2) Biotite granites have no outcrop structure. They are weakly metaluminous to peraluminous and potassic to highly potassic. Their rare earth spectra indicate that they may be derived from the partial melting of TTG granitoids. 3) Geotectonic diagrams show that the granitoids studied to the south of Godé were emplaced in an active tectonic context similar to that of present-day subduction zones.

This study, carried out in the Léo square degree (west-central Burkina Faso) in the Palaeoproterozoic domain of the Man/Léo ridge, aims to define the shapes and positions of granitic plutons and the organisation of deformation structures using aeromagnetic data. These data have shown that there are small sub-circular granitic bodies to the north of the granitic masses in this region, and a large sub-circular granitic body to the south, around which are other smaller granitic bodies. The lineament map shows that the deformation structures are organised along three main directions and largely form these sub-circular plutonic bodies. We suggest that the granitic plutons are coalescent, pending identification of the internal structures of these granites to further refine the geodynamic model.

Background: Adolescents in developing countries have limited knowledge about the prevention of STIs and unwanted pregnancies. In several African countries, risky sexual behaviour persists, including early sexual debut, multiple sexual partners, economic and sexual exchange, and low condom and contraceptive use. The purpose of this study is to assess the sexual and reproductive health knowledge and behaviour of adolescents in rural Burkina Faso in order to improve their sexual and reproductive health. Method: This was a descriptive cross-sectional study with prospective data collection conducted from 07 March to 04 April 2022 in the area of the Demographic and Health Surveillance System of the Nouna Research Centre. A questionnaire was administered to a randomly selected sample of 1202 adolescents. Results: The mean age of the adolescents was 14.1 years and 56.6% were male. Only 58.2% of the adolescents had ever heard of HIV/AIDS. Of these, 95.7% did not know their HIV status. In addition, 15.8% had ever had sexual intercourse and 2.4% had been sexually active at an early age. Almost 45% had not used any contraceptive method the last time they had sex. Condoms were the most frequently used contraceptive method (47.4%). Among teenagers, 27.6% had been pregnant at least once, 7.3% were married and the average age at marriage was 18.45 years. Almost 7% (6.9%) of teenagers had more than one sexual partner. Conclusion: Adolescents have limited knowledge about reproductive health. Risky sexual behaviour persists. Awareness campaigns need to be intensified to improve their sexual and reproductive health.

Introduction: The epidemiology of both hepatitis B virus (HBV) and hepatitis C virus (HCV) infections among drug users (DUs) is little known in West Africa. The study aimed to assess the prevalence of hepatitis B and C viruses among drug users in Burkina Faso. Methodology: This was a cross-sectional biological and behavioral survey conducted between June and August 2022, among drug users in ouagadougou and Bobo Dioulasso, the two main cities of Burkina Faso. A respondent-driven sampling (RDS) was used to recruit drug users. Hepatitis B surface antigen was determined using lateral flow rapid test kits and antibodies to hepatitis C virus in serum determined using an Enzyme-Linked Immunosorbent Assay. Data were entered and analyzed using Stata 17 software. Weighted binary logistic regression was used to identify the associated factors of hepatitis B and C infections and a p-value Results: A total of 323 drug users were recruited with 97.5% males. The mean age was 32.7 years old. The inhaled or smoked mode was the most used by drug users. The adjusted hepatitis B and hepatitis C prevalence among study participants were 11.1% and 2.3% respectively. The marital status (p = 0.001), and the nationality (p = 0.011) were significantly associated with hepatitis B infection. The type of drug used was not significantly associated with hepatitis B infection or hepatitis C infection. Conclusion: The prevalence of HBsAg and anti-HCV antibodies among DUs are comparable to those reported in the general population in Burkina Faso. This result suggests that the main routes of contamination by HBV and HCV among DUs are similar to those in the population, and could be explained by the low use of the injectable route by DUs in Burkina Faso.

Diastasis of the symphysis pubis is a rare postpartum complication. We report two cases of symphysis diastasis after dystocic delivery, in two patients who presented in the postpartum period with functional impotence, pubalgia and acute urine retention. A frontal radiograph of the pelvis confirmed the diagnosis, showing a symphyseal separation of 12 mm and 18 mm. In our case, management was mainly medical, with a favorable clinical outcome.
