Contribution of Computed Tomography to the Diagnosis of Urinary Lithiasis in a West African University Hospital

Introduction: Urinary lithiasis is defining as a condition characterized by the formation of concretions in the kidneys or urinary excretory tract. We aimed to study professional practice in CT urinary lithiasis at CHUYO. Materials and method: This was a descriptive cross-sectional study with retrospective data collection covering 3 years from January 2017 to December 2019. Results: In general, it was noted that CT scans in our environment provide all the elements needed by urologists to diagnose urinary lithiasis and its impact on the urinary system. However, there are shortcomings, particularly in terms of the accuracy of the shape and density of the stones in the CT scan reports, which does not make it easier for urologists to decide on treatment. Conclusion: Computed tomography plays a major role in the diagnosis and therapeutic management of urinary lithiasis, and its use needs to be improved in our context.

Ultrasound of the Rotator Cuff in Non-Fractured Shoulder Trauma: 30 Cases at the Yalgado Ouedraogo University Hospital of Ouagadougou (Burkina Faso)

Introduction: Ultrasound is the imaging technique of choice for the study of rotator cuff lesions. However, in the case of shoulder trauma, it is rarely requested in our context. This study aimed to show ultrasound lesions of the rotator cuff in cases of non-fracture shoulder trauma at the CHUYO in Ouagadougou. Methodology: This was a prospective descriptive cross-sectional study running from August 1 to November 30, 2017, in the medical imaging department of CHUYO. The study population consisted of patients received in the department for ultrasound in the context of non-fracture shoulder trauma. Results: We collected 20 cases (66.67%) of rotator cuff lesions out of 30 non-fracture shoulder injuries. The mean age of the patients was 27.6 years. Road traffic accidents accounted for 60% of injuries, sports accidents for 30%, and domestic accidents for 10%. Ultrasound lesions were mainly tendon ruptures (36.67%) and tendinitis (23.33%). Ruptures were non-transfixing in 90.90% of cases. The supraspinatus was the most affected (81.81%). Conclusion: Ultrasound can help diagnose rotator cuff injuries, particularly in non-fractured shoulder trauma.

Associated Factors of Dental Caries among Intellectually Disabled Persons in Specialized Centers of Ouagadougou

Introduction: Several studies have reported a high prevalence of dental caries among the people with intellectual disabilities. In order to identify the sociodemographic, clinical and behavioral factors associated with it, we conducted a study in specialized centers welcoming subjects with intellectual disabilities in Ouagadougou (Burkina Faso). Objectives: The objective of this study was to identify the factors associated with it among intellectually disabled in the specialized centers of Ouagadougou. Methods: The study was cross-sectional analytical. The survey took place between November 2020 and January 2021 among people with intellectual disabilities in reception centers receiving a grant from the Ministry of Women, National Solidarity, Family and Humanitarian Action. Data collection was done with a questionnaire adapted from the World Health Organization (WHO) and dental caries was recorded according to WHO criteria in decayed, missing or filled teeth generating a DMF index. Logistic regression was used to identify factors associated with the presence of dental caries. Results: A total of 193 participants were included in the study with an average age of 12.4 years ± 7.9. The overall prevalence of caries measured with the DMF index was 58.6% 95% CI [51.2 - 65.8]. It was significantly associated with female gender (OR = 4.2;95% CI [1.4 - 12.5], p = 0,01), the clinical form of mental illness (epilepsy OR = 3.8 95%;CI [1.2 - 12.7], p = 0,02, trisomy OR = 5.0;95% CI [1.1 - 22.9], p = 0,03, motor autonomy OR = 0.2 95%;CI [0.1 - 0.7], p = 0,01) and at use of toothpaste OR = 9.33;95% CI [1.05 - 82.7], p = 0,04. Conclusion: Dental caries remains a very present pathology in most people living with an intellectual disability. Also, it is necessary to put in place prevention strategies to reduce its prevalence and improve access to oral care for these people.

Evaluation of Medical Prescribers’ Theoretical Knowledge on Medical Imaging in the Northern Region of Burkina Faso

Introduction: Medical imaging is a medical specialty that involves producing images of the human body and interpreting them for diagnostic, therapeutic purposes, and for monitoring the progress of pathologies. We aimed to assess the theoretical knowledge of doctors and interns in medical imaging in the northern region of Burkina Faso. Methodology: This was a descriptive cross-sectional survey based on a self-administered questionnaire. Prescribers knowledge was estimated based on scores derived from questionnaire responses. Results: We collected 106 questionnaires out of 163, i.e. a participation rate of 65.03%. The average knowledge score was 81.71% for the contribution of medical imaging to patient management. It was 60.02% for the indications/counter-indications of radiological examinations and 72.56% for the risks associated with exposure to radiation during these examinations. The score was 59.83% for the methods used to select the appropriate radiological examination. As regards the completeness of the clinical and biological information on the forms requesting imaging examinations, the score was 96.65%. Specialist doctors had the highest overall level of knowledge (74.68%). Conclusion: Improved technical facilities, good initial and in-service training, and interdisciplinary collaboration will help to ensure that imaging tests are properly prescribed, leading to better patient care.

Estimating the Input Power of a Power Plant Using the Efficiency of the Inverter

The study focuses on estimating the input power of a power plant from available data, using the theoretical inverter efficiency as the key parameter. The paper addresses the problem of missing data in power generation systems and proposes an approach based on the efficiency formula widely documented in the literature. In the absence of input data, this method makes it possible to estimate the plant’s input power using data extracted from the site, in particular that provided by the Ministry of the Environment. The importance of this study lies in the need to accurately determine the input power in order to assess the overall performance of the energy system.

Atlas of Elbow Soft Tissue Pathologies Using Magnetic Resonance Imaging at the Saint Camille Hospital in Ouagadougou and the Polyclinique Notre Dame de la Paix (Burkina Faso)

Introduction: The elbow is a superficial joint, particularly exposed to direct impact, forced movement, and overstrain. Our work aimed to study magnetic resonance imaging (MRI) pathologies of the soft tissues of the elbow through illustrative cases. Methodology: This was a retrospective and prospective cross-sectional study covering a period of one year, from June 2020 to June 2021, at the Saint Camille Hospital in Ouagadougou and the Polyclinique Notre Dame de la Paix. Results: In general, this study found that the pathologies diagnosed on MRI were lateral epicondylitis, subcutaneous type V elbow lipoma and liposarcoma, anteromedial cortical fracture of the radial cup, cortical detachment fracture of the lateral epicondylitis, medial epicondylitis, villonodular articular synovitis, simple dermo-hypodermatitis, sequellar fibrosis of the ulnar nerve, Workman's syndrome (median and ulnar nerves) and osteoarthritis of the elbow. Lateral epicondylitis was the most frequent pathology, and most patients consulted for elbow pain predominantly associated with pressure on the epicondyle, with relative functional impotence and, occasionally, elbow swelling. Conclusion: MRI, as a complement to ultrasound and radiography, remains the most informative examination for exploring soft-tissue pathologies of the elbow.

Chest Radiography: General Practitioners’ Compliance with Recommendations

Introduction: Chest radiography is the most frequently prescribed imaging test in general practice in France. We aimed to assess the extent to which general practitioners follow the recommendations of the French National Authority for Health in prescribing chest radiography. Methodology: We conducted a retrospective analysis study, in two radiology centers belonging to the same group in Saint-Omer and Aire-sur-la-Lys, of requests for chest radiography sent by general practitioners over the winter period between December 22, 2013, and March 21, 2014, for patients aged over 18 years. Results: One hundred and seventy-seven requests for chest X-rays were analyzed, 71.75% of which complied with recommendations. The most frequent reason was the search for bronchopulmonary infection, accounting for 70.08% of prescriptions, followed by 11.2% for requests to rule out pulmonary neoplasia, whereas the latter reason did not comply with recommendations. Chest X-rays contributed to a positive diagnosis in 28.81% of cases. The positive diagnosis was given by 36.22% of the recommended chest X-rays, versus 10% for those not recommended. Conclusion: In most cases, general practitioners follow HAS recommendations for prescribing chest X-rays. Non-recommended chest X-rays do not appear to make a major contribution to diagnosis or patient management, confirming the value of following the recommendations of the French National Authority for Health.

Contribution of Clinical Simulation in Neonatal Resuscitation Training at the University Teaching Hospital (UTH) of Bogodogo in Ouagadougou, Burkina Faso

Objective: To study the place of simulation in the learning of newborn resuscitation among seventh year medical students at the University Hospital of Bogodogo in Ouagadougou, Burkina Faso. Material and Method: Our study took place in the obstetrical gynaecology department of the University Hospital Centre of Bogodogo (UTH-B) from 15 December 2018 to 15 March 2019. We randomly selected two groups of students, with no stimulation. We recorded a theoretical questionnaire to all students at the beginning and then carried out two stimulation sessions at 1 month intervals in the competence laboratory of the National School of Public Health. Then we evaluated the theoretical and practical progress of the students over time. We analyzed our data through the Epi info software in version 3.5.1. Results: The two simulation sessions positively influenced the theoretical knowledge of neonatal intensive care for 7th year students (p = 0.0391). Neonatal resuscitation management by students is better from one simulation session to another with a statistically significant difference (p = 0.0001). Conclusion: Our study of 7th grade students showed the importance of this tool in their practical training at the University Hospital of Bogodogo. Advocacy must be organized for its acquisition in the university hospitals of Burkina Faso.

Evaluation of Clinical and Radiological Tumour Response during Neo-Adjuvant Breast Cancer Chemotherapy at Yalgado Ouedraogo University Hospital

Background: Neoadjuvant chemotherapy (NAC) is one of the treatment options for breast cancer. Its aim is to significantly reduce the size of the tumour in preparation for surgery. The aim of this work is to analyze the conditions of clinical and radiological evaluation of NAC at the Yalgado Ouédraogo University Hospital (CHUYO). Patients and Methods: This was a descriptive cross-sectional study based on the medical records of patients followed up in the cancer department of the CHUYO from 1 January 2013 to 31 December 2021. All patients followed for histologically proven, non-metastatic breast cancer and having received at least one course of NAC were included in this study. The variables were related to the socio-demographic characteristics of the patients, the indications, the protocols of NAC and the sequences of evaluation of the tumour response (clinical, radiological and anatomopathological). Results: We collected 105 cases. The average age of the patients concerned was 44 years. The most frequent histological type was non-specific invasive carcinoma in 97.1% of cases. Immunohistochemically, triple-negative patients accounted for 51.4%. At the initial stage, all patients underwent clinical exploration. Clinical measurement of the tumour was performed in 70.5% of cases. The radiological size of the tumour was determined by ultrasound in 59.1% of cases. One patient had a breast MRI. Thirty-one patients were lost to follow-up after the initial evaluation. At mid-term and at the end of treatment, clinical tumour size was performed in 38.6% and 45.6% of cases respectively. There was no breast imaging performed at mid- and end-of-treatment. CT scans were performed in all cases at baseline, mid-term and end of treatment for extension assessment but did not mention the breast tumour. The tumour response rate was not recorded. Conclusion: Clinical assessment of tumour response is almost always empirical and not quantified. Medical imaging examinations are prescribed sparingly so as not to compromise the regularity of treatment and patient assessment.

The Rate of Caesarean Sections in Burkina Faso’s Regional and University Hospitals According to the Classification System of Robson’s Ten Groups

Background: Quality assurance in labor and delivery is needed. The method must be simple and consistent, and be of universal value. The 10-Group Classification System is a simple method providing a common starting point for further detailed analysis within which all perinatal events and outcomes can be measured and compared. Objective: The purpose of this study was to analyze cesarean section (CS) rates using the classification system of Robson’s ten groups and to identify the main contributors to the overall CS rate in Burkina Faso’s regional and university hospitals. Materials and Method: A cross-sectional study with retrospective collection was carried out. All women who gave birth between July 1, 2017 and June 30, 2018, in the Regional Hospital Centres (RHC) and University Hospital Centres (UHC) of Burkina Faso were classified according to the Robson ten-group method. The overall CS rates and in each Robson group were calculated, as well as the contribution of each group to the overall CS rate. Results: The CS rate was 26.5% (8543 out of 32,240 deliveries) during the study period. nulliparous women with single term pregnancy in cephalic presentation during spontaneous labour (group 1), multiparous women with single pregnancy in cephalic presentation, gestational age ≥37SA, spontaneous labour (group 3) and multiparous women with previous CS (group 5) were the main contributors (67.7%) to the overall CS rate. In addition, we observed a variation in CS rates between different hospitals, especially among women with full-term pregnancies in cephalic presentation without previous CS (groups 1 to 4), showing large differences in emergency obstetric and neonatal care across the country. Conclusions: Women in groups 1, 3 and 5 were the most important contributors to the overall CS rate in Burkina Faso. It appears that efforts to reduce the overall rate of CS should focus on vaginal delivery on the scarred uterus, reduction of CS rates in nulliparous women with full-term pregnancy in cephalic presentation (groups 1) and proper monitoring of multiparous women with full-term pregnancy in spontaneous labour (group 3).

CT Aspects of Psychomotor Delays in Children Aged 0 to 5 Years at Bogodogo University Hospital (Ouagadougou)

Background: Psychomotor delays in children are mainly investigated by CT imaging, due to the low availability and accessibility of magnetic resonance imaging in our context. Our aim was to study the CT aspects of psychomotor retardation (PMR) in children under 5 years of age at the University Hospital of Ouagadougou. Materials and Methods: Descriptive study with retrospective collection carried out over a period of twelve months (from September 2020 to August 2021). Our study focused on the reports of cranioencephalic CT scans performed on children aged 0 to 5 years, in whom a clinical diagnosis of psychomotor retardation had been made. Variables studied included socio-demographic data, clinical data, technique of CT examination, description of lesions and normality or not of the conclusion. Results: Cranioencephalic CT in children aged 0 - 5 years represented 9.78% of all CT scans performed in this age group. The sex ratio was 1.39. The mean age of the subjects in these reports was 18.31 ± 13.97 months and the modal class was [13 - 24] months. The CT scan was considered pathological in 85.10% of cases (n = 57). The most frequently noted encephalic anomalies were cerebral atrophy isolated in 54.4% of the cases (n = 31) or associated with other lesions in 30.1% of the cases (n = 17). Hydrocephalus was noted in 19.5% of the cases (n = 11). Conclusion: The lesions were mostly sequelae of cerebral ischaemia or cerebromeningeal infections. There were few cerebral malformations. There was no tumour etiology noted.

Maternal Mortality in the Gynecology-Obstetric Department at the Yalgado Ouedraogo University Hospital Center (CHUYO), Burkina Faso: About 181 Cases Collected from January 1^stto December 31^st2016

Objective: To study maternal mortality in the obstetrics and gynecology department at Yalgado Ouedraogo teaching Hospital Center. Patients and Methods: We conducted a cross-sectional retrospective and descriptive study of 181 cases of maternal deaths during study period. The parameters studied were sociodemographic characteristics, the causes of death, the clinical data and the contributing factors. Results: The maternal mortality ratio was 2624 per 100,000 live births. The mean age of death was 26.79 with extremes of 15 years to 40 years. Direct obstetric causes accounted for 58% dominated by hypertension and complications, hemorrhage during pregnancy and postpartum, and obstetric infections. The indirect obstetric causes were 42% dominated by non-obstetric infections and chronic anemias. In addition to the delay in consultation and delay in care, the lack of antenatal care was the contributing factor to maternal deaths. Conclusion: Maternal mortality remains a public health problem in view of its high ratio. The reduction of this scourge will inevitably go through a health insurance that will allow the supply of quality care.

Contribution of Simulation to the Skills Laboratory for the Learning of Obstetrical Examination in an African Setting with Limited Resources

Objective: To evaluate the interest of the simulation in the learning of the obstetric examination of parturient by medical students. Materials and methods: It was an analytical cross-sectional study that took place from 1 to 28 February 2020 at the Yalgado Ouedraogo Teaching Hospital in Ouagadougou, Burkina Faso. The study population was made up of medical students at the Doctorate II level. The previous experience of the students in the obstetric examination of the parturient, the contribution of the simulation on their feelings and on their skills towards this examination were studied. The Mc Nemar Chi2 test was used to compare percentages on paired samples. Results: The level of difficulty in performing the obstetrical examination in the parturient evolved downwards after the practice of the simulation. The stress level to perform the obstetric exam has been significantly reduced. On the other hand, confidence has increased. The students’ ability to appreciate each of the elements of the obstetric examination studied had improved after the practice of simulation. Conclusion: The simulation in the skills laboratory was a great contribution and the acquisition of models of better fidelity would help to improve the contribution to the confidence building and the acquisition of skills by learners.

CT Scanning in Children in a Country with Limited Resources (Burkina Faso)

Objectives: To carry out the assessment of CT scans in children at the Charles de Gaulle University Hospital Center (CGUPH). Patients and Methods: This was a retrospective collection descriptive cross-sectional study conducted from July 1 to November 29, 2021 in the Radiology Department of the CGUPH, having included computed tomography (CT) reports of patients under 18 years of age. The variables explored were the data reported on CT reports (type of scan, reason for examination, dose delivered, and abnormalities described). Results: Two hundred and ninety explorations were collected. The average age was 2.93 years with extremes of 0 and 17 years. The sex ratio was 1.35. Computed tomography scans mainly explored the cranioencephalic, spinal and abdominal stages. The most common reasons for exploration were fetal suffering and head injuries. The most frequently described lesions were anoxo-ischemic sequelar lesions. Mean irradiation doses were 1096 ± 670 mGy·cm for the cranial-encephalic stage, 603 ± 332 mGy·cm for the spine and 311 ± 395 mGy·cm for the thoracic stage. Conclusion: CT in children mainly explored the brain and concerned children under 5 years. Anatomical irradiation doses were higher than diagnostic reference levels in several countries. Optimization of scanning protocols and availability of MRI would reduce ionizing radiation in children.

External Hemorrhoidal Thrombosis in Recent Births at the Maternity Ward of Saint Camille Hospital in Ouagadougou

Introduction: External hemorrhoidal thrombosis is a clinical is the most common postpartum proctologic accident. The aim of this work was to study hemorrhoidal thrombosis in recent mothers, in order to help improve its management. Patients and Methods: This was a descriptive and analytical cross-sectional study that was carried out at Saint Camille Hospital in Ouagadougou, Burkina Faso. Data collection was prospective and took place over a period of three months from September 1 to November 30, 2019. The study population consisted of recent births. The interview with the patients and their physical examination enabled the collection of data. Results: During the study period, 384 women were examined and 56 (14.6%) of whom presented with external hemorrhoidal thrombosis. The average age of patients who presented with external hemorrhoidal thrombosis was 29 years ± 5.2. The external hemorrhoidal thrombosis appeared in the form of a painful swelling at the level of the anal margin. In multivariate analysis, dyschezia and personal history of hemorrhoidal disease were risk factors for external hemorrhoidal thrombosis in the postpartum period (OR = 37.4 [6.8 - 205.7];OR = 23.9 [3.3 - 174.2]. Consumption of fruit and foods rich in dietary fiber were protective factors against the occurrence of this risk (OR = 0.02 [0.002 - 0.3]). Conclusion: External hemorrhoidal thrombosis remains a complication to be taken into account during the monitoring of postpartum women. It is important to encourage pregnant women to consume foods and fruits rich in fiber seem to reduce the risk of its occurrence.

Correlation between Ultrasound Aspects of Fibrosis and Fibroscan Outcomes of Patients with Chronic Hepatitis B Virus

Background: The assessment of liver fibrosis is an essential part of the fol-low-up of patients with chronic HBV. Ultrasound and fibroscan are two com-monly used non-invasive examinations and the purpose of this study is to as-sess the correlation between the results of these two examinations in the as-sessment of liver fibrosis. Methodology: This was a descriptive and analytical cross-sectional study with retrospective collection over a period of 30 months from January 01, 2018 to June 30, 2020 on the correlation between the ultra-sound aspects and the results of the fibroscan of patients with chronic carriers of Hepatitis B virus at the Teaching Hospital of Bogodogo and at the faith-based health center CANDAF. Results: A total of 85 patients with fibrosis were collected. The 30 - 40 age group was the most represented (41.18%), with a male predominance of 52.94%. The patients with a married life were the most represented (77.64%), the social stratum the most represented were the middle managers (32.94%). University level was predominant among educa-tion levels (45.64%). The personal history was traditional circumcision (34.12%), excision (21.18%), manicure (16.47%). The circumstances of the findings were blood donation (34.12%), screening (21.18%), fortuitous findings (16.47%). The association between echostructure and fibrosis on the fibroscan scan was significant (homogeneous hyperechoic echostructure p = 0.0028 and granular echostructure p = 0.0001). Fibrosis on scans had a significant associa-tion with liver contour (Regular contours p = 0.0009 and p = 0.0002). Fibrosis on CT scan had a significant association for the diagnosis of fibrosis on ultra-sound (p = 0.0002 for hepatic steatosis and cirrhosis and p = 0.0013 for hepat-ic dysmorphia), on the other hand, no significant association for hepatomegaly (p = 0.8883). Conclusion: Detecting the presence of fibrosis and monitoring its progression improves the management of patients with chronic liver disease. Ultrasound scans and fibroscan are complementary in the follow-up of pa-tients with chronic HBV.

Factors Associated with Prolonged Poor Glycemic Control in Type 2 Diabetes Mellitus (T2DM) Patients Followed in the Department of Internal Medicine at the Yalgado Ouedraogo Teaching Hospital, Ouagadougou (Burkina Faso)

Background: Achieving and maintaining glycemic targets are a challenge for health practitioners around the world. We aimed to study the factors associated with prolonged poor diabetes control in the cohort of T2DM patients monitored and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital in Ouagadougou in order to optimize therapeutic education in these patients. Methodology: This was a descriptive and analytical cross-sectional study combining retrospective data collection from the last year of patient follow-up and prospective collection of some information. The study included all diabetic patients, aged at least 18 years old, followed and treated in the Department of Internal Medicine at the Yalgado OUEDRAOGO Teaching Hospital between January 1, 2010 and December 31, 2018 following a systematic random sampling with a sampling step of 10. The variables collected were sociodemographic, anthropometric, lifestyle, cardiovascular risk factors and diabetes-related characteristics. To determine the risk factors associated with prolonged poor glycemic control, we performed modeling using logistic regression. All variables associated with prolonged poor glycemic control, in bivariate logistic regression with a p-value less than 0.20 were included in the full model. Later, we used a stepwise descending method to obtain the final model, which was then tested by a receiver operating characteristic (ROC) curve. The significance threshold was set at 5%. Raw and fitted Odds-Ratio (OR) and 95% confidence interval were presented. Results: 270 patients were included. Prolonged poor control of diabetes mellitus was observed in 73.70%. The mean age was 55.97 years (SD: ±11.52) and the sex ratio was 0.6 in favor of female. The mean time since diabetes mellitus diagnoses was 5.85 years (SD: ±5.15). A monthly gain of 92.62 USD (50.74%) for average diabetes mellitus care expenditures of 55.82 USD (SD: 28.25) was reported. An overweight (55.92%) and hypertension (41.85%) were reported. Diabetes mellitus was complicated in 68.15%. Patients were supported by their families in the management of their diabetes mellitus in 85.19%. In multivariate analysis with bivariate logistic regression, low level of formal education (OR = 8.34, 95% CI [1.97 - 35.22];p < 0.01), family support for diabetes mellitus management (OR = 0.65, 95% CI [0.45 - 0.94];p = 0.02), presence of abdominal obesity (OR = 2.27, 95% CI [1.08 - 4.77];p = 0.03), presence of a history of hospitalization (OR = 7.39, 95% CI [2.97 - 18.39];p < 0.01), poor adherence to antidiabetic treatment (OR = 2.97, 95% CI [1.42 - 6.18];p < 0.01), and the presence of microangiopathy (OR = 5.05, 95% CI [2.36 - 10.81];p < 0.01) were the factors independently associated with prolonged poor control of T2DM, with a ROC curve of 0.88, which reflects a very good sensitivity and specificity of these factors. Conclusion: The imbalance of T2DM is multifactorial. Lifestyle, family environment, and compliance seem to be essential to ensure good glycemic control. Healthcare practitioners should take these elements into account in their daily patient assessment. A predictive score would be a tool to help identify patients at risk of diabetes imbalance and would contribute to improving their management.

Hemostasis Hysterectomies in a Low Resources Country: Epidemiological, Clinical, and Therapeutic Aspects

Background: The perilous path of the African woman’s pregnancy often ends in difficult situations putting her life in danger. One of the solutions to save her is often to “remove” her uterus, in a hemorrhage and emergency context. It is the hemostasis hysterectomy. It’s generally practiced in difficult conditions with complicated operative follow-ups. The tragedy is that finally the patient will die (almost 1 time out of 2 in our study). This is the sad reality of resource-limited countries. How many women will continue to die under these conditions? This study attempts to explore the different aspects of this reality. Objective: To study the epidemiological, clinical, and therapeutic aspects of hemostasis hysterectomies at the Teaching Hospital of Souro Sanou University Hospital in Burkina Faso. Methodology: This was a prospective cross-sectional descriptive study conducted over 12 months from January 1 to December 31, 2015. Included in our study were all patients received in our department and who required a total or subtotal hysterectomy in the management of a severe postpartum hemorrhage, during the study period. Results: The frequency of hemostasis hysterectomies was 0.4% compared to all deliveries. The average age was 29.65 years old. The average parity was 4.3. Multiparas and large multiparas accounted for 65%. The main indications were uterine rupture (40%) and uterine inertia (60%). Hysterectomy was subtotal in 95% of cases. Maternal morbidity was dominated in 90% of cases by hemorrhagic shock, hemostatic disorders, and obstetrical fistulas. The prognosis was poor, with 8 deaths or 40% of cases. Conclusion: Better management of pregnancy and childbirth would reduce cases of hemostasis hysterectomies. The availability of blood products would improve the maternal prognosis.

Maxilla Voluminous Bone Sequesters: About 4 Clinical Cases Treated at CCTOS in CHU Cocody

Introduction: Jaw osteitis is an inflammatory disease of bone tissue causing aseptic necrosis of bone. This study aims to clarify the etiologies of osteitis of the jawbones and to describe the clinical and radiographic aspects of extensive forms. Cases Presentation: Our study concerns the clinical and radiographic examination of 4 cases of voluminous bone sequesters. The causes of osteitis are mainly infectious and due to late consultations of our populations. The development of these maxillary osteitis leads to the formation of large bone sequesters. Conclusion: The evolution towards voluminous sequesters is a combination of dental infection, poor oral hygiene, late consultation and traditional treatment.

Haematological and Biochemical Variations in Cervico-Facial Cellulitis of Dental Origin in the City of Ouagadougou (Burkina Faso)

Background: Cervicofacial cellulitis is a severe infection and is responsible for a major disruption of host homeostasis. The aim of this work was to describe the haematological and biochemical variations of cervico-facial cellulitis. Methods: This was a cross-sectional study conducted from 1 January to 31 December 2020. All patients hospitalized for cervico-facial cellulitis of dental origin were included in the study. The usual parameters of descriptive statistics were estimated for each variable. Results: Our sample consisted of 166 patients. The average age of patients with cervicofacial cellulitis in our study was 39.9 ± 15.39 years. Red blood cell count was low in 55.5% of patients and hyperleukocytosis was noted in 89.16% of patients. Platelets were normal in 43.14% of patients and 78.43% of patients had a low haematocrit (haemodilution). Anemia was noted in 64.7% of patients. In addition, 61.0% of patients had elevated uricemia and 31.17% had elevated creatinemia. Conclusion: Cellulitis is still a common condition in less privileged environments. Its diagnosis can be guided by clinical and biological findings. Consistent education of the population on oral health, and the control of biological disorders that result from it, are sufficient to greatly reduce its prevalence and the appearance of complicated forms.
