Introduction: The acronym SAPHO (Synovitis, Acne, Pustulosis, Hyperostosis and Osteitis) is a syndrome combining osteoarticular and cutaneous manifestations. It occurs mainly between the ages of 30 and 50. Sternocostoclavicular hyperostosis is one of the main distinguishing features. We report a case of SAPHO in Dakar diagnosed by bone scintigraphy. Observation: 28-year-old Senegalese women presented with left shoulder pain and relative functional impotence for over 2 years. Examination revealed right sternoclavicular hyperostosis and left shoulder pain on palpation. Questioning revealed a history of acne and hyperostosis of the right first toe. Bone scintigraphy, performed after injection of 630 MBq of 99mTc-HMDP, revealed: hyperfixation of the bilateral (right++) manubrio-sternal and sternoclavicular junction, producing the classic bull’s horn image;hyperfixation of the left shoulder with an inflammatory appearance;hyperfixation of the sacroiliac joints suggestive of bilateral sacroiliitis;hyperfixation of the right first toe;two mandibular hyper fixations probably related to dental damage. This scintigraphic appearance in one was strongly suggestive of SAPHO syndrome. Conclusion: SAPHO syndrome, related to spondyloarthropathy, associates cutaneous and osteoarticular signs. It is characterized by frequent delays in diagnosis due to poor recognition. Soy is an invaluable diagnostic tool, enabling us to assess the extent of the disease and its evolution.

Introduction: Children involved in road accidents most often suffer head or limb injuries. The severity of these injuries varies according to the age of the child, the type of road user and whether or not protective devices are used. The aim of this study was to carry out a census of admissions and to identify the epidemiological and clinical profile of children involved in road traffic accidents at Donka National Hospital. Methods: This is a descriptive cross-sectional study of children involved in traffic accidents over a 3-month period from September 1 to November 30, 2021. All children admitted to the emergency department for a traffic accident were included in the study. Results: During the study period, 435/530 children (82.1%) were victims of road accidents. Boys accounted for 54.94% of cases, compared with 45.06% for girls. The age group most affected was 12-17 years old (48.97%). October had the highest accident rate (36.4%). Pedestrians are most affected (52.87%). Bicycles and mopeds were involved in 59.77% of accidents. Head injury was the most frequent pathology (33.33%). The study showed that 12.64% of victims were referred to intensive care, pediatric surgery, etc. We recorded 8 cases of death (1.84%). Conclusion: This study highlighted the characteristics, incidence and risk factors for accidents in children admitted to emergency departments. Accident prevention, particularly serious accidents in children, requires more precise knowledge of the factors and circumstances leading to their occurrence.

Appendicitis bilharzia is a very rare condition and we report 3 cases of this pathology that sense clinical and biological similarities with bacterial appendicitis. The etiological diagnosis was exclusively histopathological, this allowed to highlight eggs of Schistosome in the appendicular wall in the three patients. The surgical treatment was supplemented by a specific medical treatment based on praziquantel. The surgical suites were simple for 2 patients, complicated by superficial parietal suppuration in a patient.

Retroperitoneal soft tissue sarcomas in the retroperitoneal/intra-abdominal regions represent 10% - 15% of all cases of soft tissue sarcoma. Liposarcomas, which are the most common histological type, account for 20% - 45% of retroperitoneal/intra-abdominal sarcoma cases, and 20% of liposarcomas cases are primary retroperitoneal liposarcomas. Surgical resection in case of malignancy remains the treatment of choice for liposarcomas, according to the guidelines of most major international companies. Our goal was to improve the management of retroperitoneal liposarcoma. This was a 65-year-old patient, with no medical or surgical history, who was referred to us for abdominal swelling, in whom clinical and paraclinical examination found retroperitoneal liposarcoma stage IV, and the surgical treatment consisted in making a tumor reduction. Conclusion: Retro-peritoneal liposarcoma is an undervalued malignant tumor, and the diagnosis is often late.

This is a review of the first 10 coronary artery bypass surgeries performed by the local team. The mean age was 62 years old [45 - 74]. The patients were predominantly male, with a M/F ratio of 4:1. Cardiovascular risk factors were mainly myocardial infarction (MI) (60%), hypertension (50%), obesity (40%) and diabetes (30%), with at least two risk factors per patient. Angina was the main symptom (80%). The average time from presentation to surgery was 8 months. The mean Euroscore 2 was 2.92 ± 1.65 [1.33 - 6.60]. Coronary angiography revealed an average of 2 lesions per patient, with 3-vessel involvement in 70% of cases: the Interventricular artery (IVA) (100%), the right coronary artery (90%) and the circumflex artery (70%). On echocardiography, the mean Left ventricular ejection fraction (LVEF) was 59% [33% - 76%]. All patients underwent median sternotomy with bypass grafting. The average duration of the cardiopulmonary bypass was 150 min [46 - 275 min];that of aortic clamping, 120 min [43 - 232 min]. The grafts used were internal thoracic artery (ITA) in 100% of cases (80% on the left and 20% on the right), and the great saphenous vein (GSV) in 60% of cases (50% on the left and 10 on the right). Double bypass was performed in 60% of cases, single bypass in 30% and triple bypass in 10%. The bypasses were performed on the IVA (100%), the middle lateral of the circumflex (30%) and the bisector (20%). The average time to extubation was 11 hours and the length of stay in the intensive care unit was 7 days [03 - 17 days]. One patient had a reoperation on Day 0 post-op. The average hospital stay was 13 days [06 - 27 days]. Complications occurred in nine of the patients (90%), with a predominance of infectious and neurological complications. Overall operative mortality was 3%, all in intensive care.

Objectives: The main objective was to evaluate antibiotic prescribing in the Department of Pediatrics at Gabriel Touré teaching hospital. Methods: This was a prospective descriptive study conducted from September 1 to November 31, 2018, in the Department of Pediatrics at Gabriel Touré teaching hospital. All children aged 0 to 15 years hospitalized for any pathology during the study period and having received at least one antibiotic had been included. Results: We collected 445 children’s records out of 1032 admissions during the study period, representing a hospital frequency of 43.1%. The sex ratio was 1.3%. The 2 - 5 age group accounted for 48.1%. Fever was the reason for consultation in 45.6% of cases. Patients’ general condition was altered in 60% of cases. The fathers were blue-collar workers in 65.4% and the mothers housewives in 85%, and had no education in 42.9% and 64.5% respectively. Hepatomegaly was present in 18.2%, splenomegaly in 9.6% and peripheral adenopathy in 3.1%. The site of infection was pulmonary in 37.6% and ENT in 9.2%. Bacterial infection was assumed on admission in 54% of cases, and meningitis in 57.7%. The discharge diagnosis was malaria in 54.6%, severe acute malnutrition in 18.6% and meningitis in 6.7%. The death rate was 3.8%. Neutrophilic leukocytosis was present in 47.3% of patients. CRP was positive in 85% of patients. Blood cultures taken in 27.6% of patients were positive in 5. CSF analysis in 30% of patients showed elevated leukocytes in 6.5%. No cultures were positive. Antibiotic prescription was justified by infectious hypotheses in 43.1% of patients. β-lactam antibiotics were prescribed in 98.6%. Antibiotic therapy was not adapted to national/international recommendations in 68.3% of cases, and was not justified in 16.3% of cases on D5 of hospitalization. Conclusion: Antibiotic use was justified in more than half of patients, but remained inadequate in almost two-thirds of cases, in line with national and international recommend

Agro-Climatic Risks Analysis in Climate Variability Context in Ségou Region

引用

Open Journal of Statistics 2023年第1期13卷 170-193页

作者： Diop amadou Barro Diakarya Université de Ségou République du Mali Région de Ségou Université Thomas Sankara Burkina Faso Ouagadougou

In the Sahel region, the population depends largely on rain-fed agriculture. In West Africa in particular, climate models turn out to be unable to capture some basic features of present-day climate variability. This study proposes a contribution to the analysis of the evolution of agro-climatic risks in the context of climate variability. Some statistical tests are used on the main variables of the rainy season to determine the trends and the variabilities described by the data series. Thus, the paper provides a statistical modeling of the different agro-climatic risks while the seasonal variability of agro-climatic parameters was analyzed as well as their inter annual variability. The study identifies the probability distributions of agroclimatic risks and the characterization of the rainy season was clarified.
