Introduction: Male infertility is defined as the inability of a man to impregnate a woman after 12 months of regular sexual intercourse without contraception. Objective: To improve the state of knowledge on the profile of the infertile man in Guinea. Methodology: We conducted a prospective, descriptive study over a period of 6 months from October 1st, 2020 to March 31st, 2021. Results: We collected an overall number of 71 patients seen onroutine consultation for infertility. They had a mean age of 36.4 years. More than half of our patients were monogamous (79% of cases). Civil servants were the most affected with 38.02% of cases. Primary infertility was dominant in 65% (n = 46) of cases. On clinical examination, varicocele was the most remarkable abnormality with 88.73% (n = 63) followed by testicular hypotrophy with 59.15% (n = 42). Azoospermia was the most frequent sperm abnormality with 22.54% (n = 16) followed by oligospermia with 15.49% (n = 11). Hormonal assessment based on FSH and LH was performed in 16 patients with azoospermia (22.53%). FSH elevation was associated with azoospermia in 6 patients, i.e. 8.45%, azoospermia associated with a normal FSH level accounting for 14.08% in our series. Conclusion: In our practice, male infertility is becoming more and more of a concern due to the increasing number of patients seeking treatment. The scarcity of a medical assistance for procreation unit alongside with more efficient diagnostic means constitutes a handicap for its management.

为了向消费者提供高质量和可靠的电力,必须进行电力管理,使得从发电侧,通过变速器然后到配电侧有稳定的电力流动。微电网是传统电网的缩影,也需要适当的电力管理。微电网大多数时间靠近负载中心连接,使用可再生能源,如太阳能光伏板,风力涡轮机,微型涡轮机等。微电网既可以在电网连接模式下运行,也可以在自主模式下运行。因为大多数微电网是使用电子接口分布式发电来操作的,所以它们具有低惯性。因此,需要进行适当的控制,以便在瞬态情况下几乎没有影响。要控制以确保可靠和高质量功率流的组件是实际或有功功率,无功功率,电压和频率。无论负载条件或发电条件如何,在操作微电网时应该减少干扰。应该有足够的有功功率和适当的无功功率补偿。无论何时发生加载,都必然会降低频率。然而,这应该以这样的方式控制,即没有振荡会导致进一步的问题。与具有并联连接的逆变器的微电网相关的另一个问题是流过这些逆变器的循环电流。这种现象的主要影响是功率质量差和可能的热量累积。这种效果肯定是不可取的,需要加以解决。在这项研究中,有两个并联的逆变器。还连接了本地负载以及一般负载。本地负载在不同时间连接,其中一个负载在一段时间后断开。这是为了在装载和卸载期间测量实际功率和无功功率的流量。在此期间也观察到频率。最后,还观察流过逆变器的循环电流,看它足否在可接受的范围内。所有这些都是使用MATLAB Simulink实现的,结果将在此后生成。

Trauma to the male genitalia is not very common and mainly affects a young population. There is probably a particular instinct in men to defend their external genitalia;indeed, in the flaccid state, the penis is little exposed, and fairly well protected and its mobility allows it to move with the impact of trauma and thus reduce the vulnating force. Open trauma is rare, as is testicular dislocation, the most common being closed trauma. Testicular trauma is an uncommon accident that affects young people. Trauma is most often caused by road and traffic accidents. Animal bites are rare, as is genital self-mutilation related to a psychiatric disorder. Surgical exploration is the rule except in cases of moderate testicular trauma. Our objective was to report our experience in an emergency context where treatment is poorly codified and to review the literature. We recorded four patients with external genitalia trauma managed in the urology department from April 2013 to March 2022. Our patients were children with open genitalia trauma following a traffic accident, scrotal injuries were encountered in three patients, and additional penile injuries in one patient. All patients were treated surgically. The follow-up was straightforward.

Objective: To study the clinics and therapeutics of testicular cancer not descended in Senegal. Patients and Methods: This is a retrospective study over a period of 15 years between January 1997 and January 2012. It focused on 07 patients. Results: The average hospital incidence was less than one case per year. The average age of patients was 30.7 years with a median of 28 (range, 21 years and 38 years). The reasons for consultation were dominated by the existence of an abdominal or pelvic mass associated with an emptiness of the stock market. Orchiectomy was the main therapeutic gesture. It was performed by transperitoneal route. CT-TAP was performed in all cases and revealed a tumor independent of the liver of the spleen or kidneys, developed on an undescended testicle. Four cases of lumbar-aortic lymph node metastasis were noted. Histologically, we noted four cases of embryonic carcinoma and three cases of seminoma. Four patients died within six months postoperatively. Two in an intestinal obstruction chart, one in a peritoneal carcinomatosis chart and one patient in a pulmonary embolism chart. Two had a 4-year survival without recurrence. One patient had a 7-year survival without recurrence. At the time of the counting, these three patients were lost sight off. Conclusion: Intra-abdominal or pelvic development of testicular cancer is rare. It constitutes a major subsequent risk of the undescended testicle.

Introduction: Ankylosing spondylitis (AS) is an inflammatory rheumatic disease characterized by predominant axial and peripheral (enthesitis, sacroiliitis) involvement affecting young subjects aged 30 to 40 years, 80% to 98% of cases are associated with HLA-B27. Objective: To determine the epidemiological profile of ankylosing spondylitis in the rheumatology department of the Ignace Deen National Hospital in Conakry (Guinea). Materials and Methods: This was a descriptive cross-sectional study carried out within the said department over a period of 18 months from July 1, 2018 to December 31, 2020, including all patients seen in consultation and/or hospitalized in the department in which the diagnosis of ankylosing spondylitis had been retained according to the modified New York criterion. The parameters studied were sociodemographic, clinical, paraclinical and therapeutic. Result: We collected 73 cases or 4.1% of ankylosing spondylitis out of a total of 1781 patients seen during the study period. The male gender was represented with 54.8% for a sex ratio of 1.2 M/F. The average age of our patients was 32.18 ± 12.44 years with extremes ranging from 17 to 54 years. Axial involvement was present in 89.9% of cases with a lumbar predominance (95.2%), followed by the sacroiliac seat (35.5%), cervical (14.5%) and dorsal at 4.8%. The pain was chronic in 93.2% of cases. The most common drug treatment was taking analgesics and NSAIDs (100%) followed by cortisone infiltration (41.1%), corticosteroids (30%), and physiotherapy (21.9%). Ankylosing spondylitis represents 83% of spondyloarthritis followed by undifferentiated spondyloarthritis (9.1%) and juvenile spondylitis (3.4%) were the most common conditions.

A foreign body in the urethra is the presence of an object in the urethra. They are often secondary, either to an erotic curiosity, û or to psychiatric disorders. The diagnosis remains clinically aided by imagery. Treatment is most often endoscopic, but in some cases the use of open surgery is necessary. We reported the case of an 80-year-old man with no history of behavioral disorders;a wooden rod was inserted into the urethra to empty his bladder. The care consisted of a meatoplasty under locoregional anesthesia. Upon discharge, the patient had a good urine flow.

作者： Lebem Togtoga Khadim Niang Papa Ndiaye Mamadou Saidou bah Department of Public Health and Social Medicine Université Gaston Berger (UGB) Saint-Louis Senegal

Introduction: At university, habits, particularly eating habits, can negatively impact well-being. This study aimed to describe lifestyle habits and dietary diversity among medical students. Methodology: This was a cross-sectional, descriptive study, carried out at the UFR 2S of the University Gaston Berger from May 23 to June 3, 2023. The collection tool focused on sociodemographic characteristics, lifestyle habits and dietary diversity. Statistical analyzes were carried out using R software. Results: A total of 471 students participated in this study. Which corresponds to a participation rate of 89.2% with a M/F sex ratio of 1.66. The age of participants, varying from 18 to 32 years, had a median of 23 years and a mean of 22.4 years with a standard deviation of 2.2 years. Among the participants, 67.2% skipped breakfast, and 28.5% did not practice any physical sports activity. Alcohol and tobacco were consumed by 2.5% and 0.6% of participants, respectively. The most consumed foods were starchy foods (97.5% of men and 98.4% of women);and the least consumed were dark green leafy vegetables (21.9% of men and 15.1% of women) and offal (16.9% of men and 11.9% of women). The dietary diversity score was low for 31.9% of men and 28.7% of women. Conclusion: Certain lifestyle habits (skipping breakfast, dining late at night, lack of sports practice) of Medicine students at UGB can prove deleterious to their well-being. These students are at risk of developing several deficiencies in terms of food groups that are underrepresented in their diet. Awareness sessions on good lifestyle habits and diet would be relevant recommendations for improving the health of these students.

种群的空间分布格局和种间关联性的研究对预测群落演替趋势和植被重建具有重要意义。文中以古尔班通古特沙漠东南部三种类型沙丘上的优势灌木种群为研究对象,在0-20m尺度上利用空间点格局分析法,基于均质泊松模型HPP和异质泊松模型IPP,采用单变量相关函数g(r)对三种类型沙丘上的灌木的空间分布格局进行研究。同时,基于完全随机模型CSR和先决条件模型AC,采用双变量g_(12)(r)函数研究了三种沙丘上灌木间的种间关联性。结果表明:1)三种沙丘上的优势灌木在均质泊松模型HPP下以聚集分布为主,在剔除生境异质性后的异质泊松模型IPP下在中小尺度上以聚集分布为主,在较大尺度上以随机分布为主;2)三种沙丘上灌木的聚集强度的大小顺序为:半固定沙丘>流动沙丘>固定沙丘;3)三种沙丘上,大多数灌木之间的种间关联性随着空间尺度的增而减小。其中,固定沙丘上的灌木在完全随机模型CSR下在0-20m空间尺度上为负关联关系,在去除生境异质性的AC模型下以正关联关系为主;半固定沙丘上的灌木在CSR模型下在0-20m尺度上主要呈现正关联关系,在AC模型下中小尺度上为正关联关系,大尺度上趋于无关联性;流动沙丘上的灌木在CSR模型下在小尺度上主要以正关联为主,在大尺度上趋于无关联性;在AC模型下灌木之间虽也以正关联为主,但随着尺度的增加最后趋于无关联性或负关联关系。研究结果可为该地区固沙植被的演替和植被的生境适应性的研究提供一定的理论基础。

Open Journal of Urology 2024年第3期14卷 173-178页

作者： Alimou Diallo Karifa Oulare Alpha Oumar Barry Thierno Oumar Diallo Daouda Kanté Ibrahima bah Abdoulaye Bobo Diallo Oumar Raphiou bah Department of Urology Sino-Guinean Friendship Hospital Faculty of Health Sciences and Technologies Gamal Abdel Nasser University of Conakry Conakry Guinea Department of Urology National Ignace Deen Hospital Faculty of Health Sciences and Technologies Gamal Abdel Nasser University of Conakry Conakry Guinea

Context and Objective: Groin hernia is a common pathology in visceral surgery (2nd rank after appendicitis), which affects approximately 4.6% of the African population. Restoring the normal anatomy of the groin region is one of the most benign interventions. However, uro-andrological complications are possible. This study aimed to contribute to the improvement of the management of urogenital complications of groin hernia surgery. Patients and Method: We carried out a prospective study of descriptive type with a duration of 6 months from 1 August 2021 to 31 January 2022. The data were collected using a pre-established survey sheet. The study covered several sites (public hospitals and private clinics) in Guinea. Results: The urogenital complications of the surgery of the hernia of the groin represented 15.22% or 14 cases out of 92 patients. The average age was 37.00 years with extremes of 20-69 years. Polygamists occupied the first place. The reason for consultation was dominated by decreased testicular volume (42.86%), followed by a desire to conceive (21.43%). Unilateral testicular atrophy represented 63.64%, bilateral 27.27%. We performed a left orchidectomy in one patient and a cystorraphy in another simple operative follow-up. The other cases consisting of testicular atrophy, due to lack of a suitable technical platform, did not benefit from any specific therapeutic treatment. Conclusion: Urogenital complications of groin hernia surgery are relatively common. Testicular atrophy was the main clinical complication. The left orchidectomy and cystorraphy were the therapeutic procedures performed.
