Introduction: The clinical manifestations of many diseases vary with age, and older people often do not show typical symptoms of the disease. The present study aims to compare the epidemiological, clinical, therapeutic and evolutionary aspects of elderly patients with COVID-19 compared to young adult patients and to identify risk factors for mortality. Patients and Methods: This was a retrospective single-center analytical study conducted from January 27, 2021 to January 27, 2022 at the COVID-19 Care Center of the Infectious and Tropical Diseases Department of the Bouaké University Teaching Hospital. The study population consisted of all patients aged at least 18 years seen in consultation and/or hospitalized with a positive COVID-19 RT-PCR. The patients were divided into two groups: younger patients (Results: Of a total of 779 patients, 644 (82.7%) were young. The median age of all patients was 41 years (IQR 32 - 54, extreme 18 and 96). Of all the patients 38.5% had a comorbidity. Compared to younger patients, chronic heart disease (61.7% vs 21.5%;p Conclusion: Elderly people with COVID-19 have a different clinical presentation from younger, characterized by more atypical symptoms. Mortality risk factors are age, dyspnoea, impaired consciousness and fever. It is therefore necessary to act on its various factors to improve the prognosis of COVID-19 in this age group.

联合收割机粮箱的籽粒输运过程中存在粘附堆积的问题,这严重影响联合收割机的作业效率。本文基于离散元法(DEM)模拟联合收割机粮箱卸粮过程中水稻颗粒群的运动,分析了粮箱壁面压力分布变化,研究了谷物颗粒群流动特性;设计搭建了微型粮箱台架,基于台架试验研究了粮箱内表面材质和操作参数下的颗粒流动特性;通过仿真和台架试验研究了不同仿真非光滑表面型式下粮箱卸粮过程中的颗粒运动。这对缓解粮箱籽粒粘附堆积,联合收割机粮箱的设计、制造和改进具有重要意义。基于DEM模拟了水稻籽粒在卸粮过程中的运动,研究了粮箱的压力分布,结果表明不同壁面的压力是不一致的,当粮箱装满颗粒时,与粮箱底部的两个倾斜壁面相比,四个垂直壁面承受的应力较低,而粮箱底部的壁面承受最高压力。以粮箱内表面材质(钢、亚克力、木材、塑料)、粮箱底部倾斜角度、螺旋搅龙转速为变量,通过仿真和台架试验研究了卸粮过程中的籽粒流动特性,研究结果表明水稻籽粒在木质表面的附着力小于在钢材和亚克力表面上的附着力,而在塑料表面的附着力大于其他材料。增加粮箱底部倾斜角度增加了水稻籽粒在表面的附着力,同时提高了螺旋钻的转速,减少了籽粒在粮箱表面的附着力。将两种不同的仿生非光滑表面型式应用于粮箱内表面,并基于仿真和台架试验研究了粮箱卸粮过程中的籽粒粘附和运动变化,结果表明水稻籽粒在非光滑仿生表面粘附的仿真和台架试验结果相似。粘附在仿生1和仿生2表面的籽粒质量均少于光滑表面。比较两种仿生表面样品上水稻籽粒的定性附着力,水稻籽粒在仿生1表面的附着力低于仿生2表面。在这项研究中,粮箱壁面压力分布、粮箱底部倾斜角度、表面材料的数据可用于粮箱制造中的设计。研究表明,仿生非光滑表面可用于谷物处理设备,以减少谷物在潮湿表面上的粘附堆积。

Introduction: With the eradication of smallpox in 1980, vaccination against smallpox ceased and there was an upsurge in cases of monkeypox. The objective of this observation is to describe the characteristics of monkeypox in the vaccinated subject. Case Report: A 45-year-old, heterosexual, rural resident was referred for a rash. The history of the disease revealed signs of acute course marked by headache, asthenia, diffuse myalgia, chest pain, fever and pruritic rash. His background is marked by vaccination against smallpox in 1977, cohabitation with game hunters and domestic animals as well as a notion of contact with a person who presented similar but more generalized signs. The physical examination revealed a conscious patient with good general state, feverish, tachycardic, eupneic presenting skin lesions in the type of striated vesicles more or less umbilical, on the scalp, face, neck, trunk and the upper limbs associated with cervical lymphadenopathy. RT-PCR was performed on a dry swab by rubbing several vesicles and a throat swab proved positive for Monkeypox Virus (MPXV). Management consisted of isolation and symptomatic treatment. The evolution has been favorable. Conclusion: The symptomatology of monkeypox is similar to that of smallpox. Without widely available treatment or prophylaxis, rapid identification of cases is essential. Vaccination of people at risk is an alternative to curb the epidemic. However, the main prevention strategy is to raise awareness of the risk factors.

Aim: Reporting the department’s experience in managing adult rectal prolapse. Methods: A descriptive study was conducted in the department of chirurgie A of the chu of point G. All patients operated on for rectal prolapse in the Department of Surgery “A” were included. Technics used were altemeier procedure and anoplasty. Results: 40 cases of complete rectal prolapse were identified. The sex ratio was 1.42. Average age was 50 years. During the study period, rectal prolapse accounted for 0.13% of all pathologies encountered (n = 40) and 3.37% of anorectal pathologies. Locoregional anesthesia was performed in all patients. In the series, 36 patients (90%) were operated on using the Altemeier procedure, anal cerclage was performed in 3 patients (7.5%), and anoplasty was performed in one patient (2.5%). Postoperative mortality was 2.5% (n = 1). The postoperative follow-up was simple in 95% of cases (n = 38). Anal stenosis was found in one patient (2.5%). Conclusion: Low-way surgery remains one of the preferred options for weakened patients exposed to anesthetic risks.
