Introduction: Pseudarthrosis (PSA) of the diaphysis of long bones still remains a current problem, despite improvements in the treatment of these fractures. Our study aims to study the epidemiological and therapeutic aspects of PSA of the diaphysis of long bones. Method: This retrospective work concerns 30 cases of non-union of the diaphysis of long bones treated in the orthopedic and trauma surgery department at Donka National Hospital, during a period of 18 months from January 1, 2019 to June 30, 2020. Results: We recruited 30 patients, 80% of whom were male, with an average age of 39.9 years. Public road accidents (AVP) represented the main cause of fractures of the diaphysis of long bones 87%, they were open in 25 cases or 83%. The fractures were located in the middle 1/3 of the diaphysis of the long bones in 50% of cases. Treatment of initial fractures was traditional in 21 cases, orthopedic in 2 cases and surgical in 7 cases. It was aseptic nonunion in 28 cases (93%) and septic nonunion in 2 cases. They were hypertrophic in 7 cases, slightly hypertrophic in 5 cases, oligotrophic in 11 cases, atrophic in 6 cases and with bone defect in 1 case. The treatment was based on osteosynthesis including 16 cases of screwed “PV” plate: 7 cases of centromedullary “ECM” nailing, 2 cases of external fixator, 1 case of broaching and 4 cases of Plastering. The results according to ASAMI criteria on an anatomical level were excellent in 19 cases, good in 3 cases and poor in 3 cases, with a union rate of 76%. And 5 patients undergoing consolidation. Conclusion: Based on the literature data and the experience of our department, the true treatment of PSA requires correct management of the initial fracture without forgetting the interest in preventing AVP which appears to be an element essential, making it possible to reduce the incidence of fractures of the diaphysis.

In this work, we proceed to an optical and microphysical analysis of the observations reversed by the MODIS, SeaWiFS, MISR and OMI sensors with the aim of proposing the best-adapted airborne sensor for better monitoring of aerosols in Burkina Faso. To this end, a comparison of AOD between satellite observations and in situ measurements at the Ouagadougou site reveals an underestimation of AERONET AOD except for OMI which overestimates them. Also, an inter-comparison done based on the linear regression line representation shows the correlation between the aerosol models incorporated in the airborne sensor inversion algorithms and the aerosol population probed. This can be seen through the correlation coefficients R which are 0.84, 0.64, 0.55 and 0.054 for MODIS, SeaWiFS, MISR and OMI respectively. Furthermore, an optical analysis of aerosols in Burkina Faso by the MODIS sensor from 2001 to 2016 indicates a large spatial and temporal variability of particles strongly dominated by desert dust. This is corroborated by the annual and seasonal cycles of the AOD at 550 nm and the Angström coefficient measured in the spectral range between 412 nm and 470 nm. A zoom on a few sites chosen according to the three climatic zones confirms the majority presence of mineral aerosols in Burkina Faso, whose maxima are observed in spring and summer.

Spondylolisthesis is a well-known neurosurgical condition, in relation with various factors. The main objective was to report the morphological and radiological hallmark of patients presenting with symptomatic spondylolisthesis. This is a prospective, longitudinal, descriptive and analytical study： 1 st April to 30th September 2014. Twenty nine patients were followed up, with female ascendance. The average age is 50 to 69 years. The most frequent level was LA-L5 and in most cases, only one level was involved. Lesions of Grade I were commonest （79.0%）. The average values of the SS （sacral slope） and PI （pelvic incidence） was respectively 36.4 ± 6.9° （17.3° to 49.6°） with a median of 37.8° and 64.9 ±9.2° （42.98° to 87.47°） with a median of 64.6°. LL （lumbar lordosis）, had a mean value of 43.8 ±10.8° （26.2° to 67.0°） with a median of 43.1°. DH （disc height） was 5 to 10 mm in most cases. A report was made with the morphology of the basin of the African woman. Our results are consistent for the most part with the literature data. This present study illustrates a female to male ration of 3. According to BMI （body mass index） assessment, 69% of patients presented with overweight. The main radiologic parameters are compromised with increasing sacral slop and PI and reduction of DH and LL. Findings are characteristic in female population.

Lumbar hernia, a Rare Cause of Intestinal Occlusion: About a Case

Surgical Science 2018年第10期9卷 351-357页

Defects of the posterolateral abdominal wall of the abdomen, lumbar hernias are rare. They represent 2% to 3% of hernias of the abdominal wall. This rarity explains the large number of short series and the absence of a well-defined therapeutic modality in the publications. Grynfeltt’s hernia at the top and Jean Louis Petit’s at the bottom are the two entities. The old lumbar hernias are bulky with a rich history and easy diagnosis. Though young, they are discreet and reveal most often by their strangulation. We report the case of a Grynfeltt hernia revealed by colonic occlusion in a 77-year-old woman who had a superior right posteriolateral tumefaction for 15 years. The hernia cure was prosthetic made by the sandwich technique. No recurrence was observed after 25 months of follow-up. Through a review of the literature, we reveal the diagnostic and therapeutic difficulties.

Metabolic Syndrome (MS) has reached a pandemic proportion and has an impact on the incidence and severity of cardiovascular pathologies. This study was conducted to evaluate the effect of different processed food commonly consumed in Maroua (Far North Region, Cameroon) on the Glycemic Index (GI). To ameliorate the follow up of MS and population’s nutrition education, a survey was conducted among 200 families. The ten most consumed meals were selected after a food survey among 200 families. The meals were mostly made of a vegetable soup associated to a high carbohydrate staple. Vegetables and cereals were processed according to the food survey results. Then, a food tolerance test was performed on 30 male volunteers living in the same region. Among them, 12 were selected with an average age of 28.25 and a mean BMI of 19.63. They were studied on separate occasions in the morning after an overnight fast. After fasting, blood glucose was taken before and (15, 30, 45, 60, 90 and 120 minutes) after eating a test meal compared to sucrose and glucose solution (33.33%) used as reference. Glycemic response curves were used to calculate the gi of each meal. Results show that GI of the tested meals varied significantly (p < 0.05) between 20 and 79. Red millet porridge with kelenkelen-beans (Cochorus oletorius-Vigna unguiculata) sauce and red millet porridge with kelenkelen-peanut (Cochorus oletorius-Arachis hypogea) sauce exhibited the lowest GI. The highest GI was observed in corn porridge associated with fresh okra (Hibuscus esculentus) or with tasba (Cassia tora)-okra-beans sauce.

Numerical Study of a Cylindro-Parabolic Cooker “Blazing Tube”

引用

Open Journal of Applied Sciences 2022年第11期12卷 1783-1795页

作者： Boureima Dianda Mibienpan Ki Wende Pouiré germain Ouédraogo Nébon Bado Sikoudouin Maurice Thierry Ky Bruno Korgo Sié Kam Dieudonné Joseph Bathiebo National Center for Scientific and Technological Research Ouagadougou Burkina Faso Laboratory of Renewable Thermal Energies University Josph Ki-Zerbo Ouagadougou Burkina Faso Higher School of Engineering (ESI) University of Fada N’Gourma Fada N’Gourma Burkina Faso

The objective of this work is to numerically determine the thermal performance of the parabolic cylinder cooker commonly “blazing tube”. These performances were determined by establishing heat balances at the different levels of the system. The equations obtained have been discretized;simplifying assumptions have been made to facilitate their resolution. We adopted Gauss Seidel’s method using MATLAB software to solve these equations. The temperatures of the coolant, the glass and the absorber were determined as a function of time and along the tube. The thermal efficiency was also determined. It emerged that the different temperatures evolve linearly as a function of the length of the tube. Yield and temperatures depend on the amount of sunshine.
