This prospective case-control study aimed to assess the prevalence of hyperhomocysteinemia and explore its potential correlation with microangiopathic complications, specifically nephropathy and neuropathy, in a cohort of both type 1 and type 2 diabetic patients. Conducted at the Marc Sankalé Center of Abass Ndao Hospital in Dakar from June to September 2018, the study enrolled a total of 106 diabetic patients, comprising 93 type 2 diabetics and 13 type 1 diabetics, who were matched with control subjects free from clinically detectable pathologies, based on sex and age ± 2 years. The mean age of type 1 and type 2 diabetic patients was 24.46 ± 8.41 years and 57.28 ± 11.28 years, respectively. Our findings revealed a statistically significant elevation in mean homocysteine levels among patients when compared to controls (12.63 vs. 9.88;p ely among those with type 2 diabetes. Within the hyperhomocysteinemia subgroup, 58% were male, and 42% were female. The analysis of neuropathy and nephropathy frequencies among type 2 diabetic patients, stratified by homocysteine concentrations, demonstrated a notably higher prevalence of diabetic nephropathy in patients with hyperhomocysteinemia compared to those with normohomocysteinemia (23.07% vs. 8.75%;p = 0.052). Similarly, diabetic neuropathy exhibited a significantly greater frequency in patients with hyperhomocysteinemia as opposed to normohomocysteinemia (80.76% vs. 50%;p = 0.005). Furthermore, our results established a significant positive correlation between homocysteine concentrations and both age (r = 0.402;p els (r = 0.461;p eloping neuropathy (OR = 3.5;p = 0.061) and diabetic nephropathy (OR = 6.092;p = 0.014), respectively.

作者： Aïssatou Aw Soda Mbaye Jean Pierre Diagne Sy el hadji malick Alassane Ba Aly Mbara Ka Serigne Sohibou Gaye Ousmane Ndiaga Senghor Lamine Ndiaye Mouhamed Ndiaye el hadj Abdellahi Seyid Papa Amadou Ndiaye Ophthalmology Department of Abass NDAO Hospital Cheikh Anta Diop University Dakar Senegal

Purpose: To show epidemiological and imaging aspects of congenital optic disc abnormalities diagnosed late. Method: It was a retrospective study, including all patients with congenital optic disc abnormalities diagnosed at a late age between January 2020 and October 2022 at the eye center of Abass Ndao Hospital. Complete ophthalmological examination was performed with eye imaging according to the cases. Results: 09 patients (10 eyes) were diagnosed with congenital optic disc abnormalities. The mean age was 29 years, with a sex ratio of 0.8. Three patients had consulted for unilateral decreased visual acuity since childhood, two for sudden vision loss and in four cases the diagnosis was fortuitous. Visual acuity was ranged from 1/200 to 20/20. Fundus examination showed myelinated retinal nerve fibers in four eyes, optic disc pit in three eyes including two complicated by maculopathy, two cases of morning glory syndrome and a case of pseudoduplication of the optic disc. Optical coherence tomography, ocular ultrasound B and OCT-Angiography were performed according to the cases. Conclusion: Congenital optic disc abnormalities are often diagnosed late. They are potentially amblyogenic and complications are not rare, worsening the visual prognosis. Their screening should be systematic by ophthalmological examination in newborns.

Introduction: Autoimmune polyendocrinopathies (AP) represent a group of rare concomitant pathologies, making them underdiagnosed. The objective was to study their profile at the Medical Clinic II of the Abass Ndao Hospital. Patients and Methods: This was an observational, descriptive and analytical study, lasting 24 months, from January 1, 2020 to December 31, 2022. We assessed the epidemiological, clinical and paraclinical characteristics of the patients and classified the APs found. Results: We included 40 patients divided into type III (38 cases) and IV (2 cases). A female predominance was noted with a sex ratio of 0.21. The mean age was 38.6 years. A family history of component diseases of autoimmune polyendocrine syndrome (APS) was found in 62.5%. Goiter (80%) was the main clinical sign present. All 38 patients with ISAP-3 had autoimmune thyroiditis, including 29 cases of Graves’ disease (72.5%) and 9 cases of Hashimoto’s thyroiditis (22.5%). They were associated with either type 1 diabetes (57.9%), Biermer’s disease (21.1%), vitiligo + alopecia (18.4%), lupus (2.6%). The 2 patients with AP-4 had Biermer’s disease associated with either Addison’s disease or type 1 diabetes. Management depended on the pathologies present and their possible complications. The immunological phenomena were also controlled. Conclusion: This series is globally similar to the literature. The polymorphous character of the clinical pictures requires a better collaboration between specialists leading to a clinical and holistic synthesis.

Introduction: Cancellation of elective surgery is common in developing countries. This decision is difficult to make as it generates economic and organizational consequences for the healthcare facility and an additional source of stress for patients and their caregivers. This study aimed to analyze the various aspects of this medical problem. Patients and Methods: We conducted a prospective and descriptive study over six months (from January 1st, 2017, to June 30th, 2017) at the pediatric surgery department of Aristide Le Dantec University Teaching Hospital in Senegal. Results: Ninety-one cases were collected. The cancellation rate was 20.8%. Infants were affected in 36.3% of cases. Among anesthesiologists, 83.5% were residents, and 16.5% were specialists. Cancellation in nephroblastoma children with an indication for extended nephrectomy represented 15.4% of cases. Concerning reasons for cancellation, comorbidities, dominated by respiratory infections, accounted for 28.5% of cases, patient absences for 24.2%, and issues related to the anesthesiologist for 17.6%. Cancellations were avoidable in 33% of cases. Patients were responsible for cancellation in 37.4% of cases, the healthcare system in 33%, and medical reasons in 29.7%. Conclusion: Our findings suggest that one-third of cancellations could have been avoided with improvements in the healthcare system. Actions should be taken to reduce the cancellation rate in our context.

Introduction: Diabetic microangiopathies are common, but their time to onset in a diabetic patient varies from subject to subject. The aim of our study was to study the correlation between renal and ophthalmic disorders in patients with type 2 diabetes. Patients and methods: This longitudinal, analytical study took place from March 1, 2018 to March 31, 2019 at the Abass Ndao University Hospital Center. It was studying retinal involvement in diabetic patients with glomerulopathy. Results: Of the 100 cases of diabetic glomerulopathy, they are divided into 70 women and 30 men with an average age of 58.2 years. The average duration of diabetes was 6.1 years and their average glycated hemoglobin (HbA1c) was 8.1%. Only 37% of patients had an HbA1c level below 7%. The other cardiovascular risk factors were high blood pressure (HBP) (39%), dyslipidemia (36%), and obesity (15%). Among these patients, diabetic retinopathy was present in 21% of the cases. Retinopathies were more frequent in the group of patients diagnosed with diabetes for less than 6 years (69%) and in patients with chronic renal disease with slightly reduced glomerular filtration rate (GFR) (34%). Conclusion: Our study allowed us to conclude that during the course of type 2 diabetes, the onset of chronic kidney disease does not systematically imply the presence of diabetic retinopathy. It is thus important to make screenings and assessments of systematic complications.

Background: School is a space where children are exposed to the social and psychosocial environment that can affect their health. In Senegal, the prevalence of dental caries is high in classic schools according to fragmented data, and unknown in the koranic school (Daaras). Objective: The objective is to describe the disparity of dental caries in the schoolchildren (talibes) of Daara of Koki. Method: A cross-sectional study was carried out on 400 talibes aged 7 to 12 years. Dental caries and socio-demographic data were, respectively, collected by clinical examination and questionnaire. Results: The sex ratio was 9, the mean age of 9.9 ± 1.5 years and the mean length of stay in the Daara was 2.3 ± 1.1 years. The prevalence of dental caries was 47.4%. The average mixed DFMT index was 1.1 ± 1.5. The prevalence was 51.2% among boys, 60% among eight-year-old children and 37.4% among twelve-year-old children. By length of stay, the prevalence was 52.9% at the start and 22.2% at the end with a significant downward trend (p Conclusion: The study showed an unequally distributed of caries among talibes of Koki’s Daara. She suggests that oral health promotion policies are needed in Koranic schools and must rely on koranic teachers.

Background: Over the last 50 years, endourology has revolutionized urological practices worldwide. This is not so in many urological centers in West Africa. Although, some centers have made progress in the level of urological services that they offer;many of such centers provide rigid urethrocystoscopy services. Rigid urethrocystoscopy is an endoscopic examination that explores the urethra, bladder and prostate in men. Aims: We report the indications, results and pain assessment of rigid urethrocystoscopy in our center. Patients and Methods: We carried out a retrospective, descriptive, monocentric study in our center between January 2016 and June 2018. The study included all patients who had a rigid urethrocystoscopy under local anaesthesia. We studied the following parameters: sex, age, indications for the examination, outcomes and the pain assessment. Results: Five hundred and forty-one patients were included. The sex-ratio was 1.49. The mean age was 49.47 ± 18.48 years (12 years and 91 years). Lower urinary tract symptoms (29%) and hematuria (28%) were the most common indications. The rigid urethrocystoscopy was normal in 26.8% of patients. Bladder tumors (21.2%) were the most frequent lesions. In men, prostate tumors were more common (21%) followed by bladder tumors (17.9%), while in women, bladder tumors (26.3%) were predominant followed by cystopathy lesions (12.4%).The mean Simple Verbal Scale (SVS) score was 1.25 in women and 2.1 in men. Conclusion: Rigid urethrocystoscopy was relatively well tolerated by our patients. Hematuria was the primary indication and the main etiologies were bladder and prostate tumors.

Open Journal of Urology 2020年第7期10卷 225-232页

作者： Modou Ndiaye Ousmane Sow Babacar Sine Omar Gaye Alioune Sarr Abdoulaye Ndiath Cyrille Ze Ondo Amath Thiam Ndeye Aissatou Bagayogo Samba Thiapato Faye Ndiaga Seck ndour Aboubacar Traore Ngor Mack Thiam el hadj malick Diaw Yaya Sow Boubacar Fall Babacar Diao Alain Khassim Ndoye Urology-Andrology Department Aristide Le Dantec Hospital Dakar Senegal Urology-Andrology Department De la Paix Hospital Ziguinchor Senegal

Objective: To evaluate the factors predicting the time to progression to castration-resistant in metastatic prostate cancer under Androgen Deprivation Therapy (ADT) in our center. Patients and Methods: This is a retrospective, descriptive, analytical study in a single center over a period of 2 years. It has interest patients followed for metastasized prostate cancer under ADT. The parameters studied were: epidemiological, clinical, paraclinical, prostate specific antigen (PSA) nadir, time to nadir (TTN) and their link with the castration resistance. Results: The frequency of castration resistant prostate cancer was 28 patients per year. The mean age was 70.4 ± 7.9 years. An ECOG score ≥ 3 was more common as was the cT2c stage. The median of the initial total PSA was 489.6 ng/ml (203.3;1653.2). All patients had adenocarcinoma. The International Society of Urological Pathology (ISUP) 1 was more frequent. Bone metastases were more frequent. The medians of nadir, TTN and the castration resistance were 19.3 ng/ml (3.7;102.1), 5.5 months (3;9) and 11 months (6;15.3), respectively. The Eastern Cooperative Oncology Group (ECOG) score, clinical stage, metastatic site, the nadir and its TTN influenced the DSR. Age, lymph node involvement, initial total PSA and Gleason score did not influence the castration resistance. Conclusion: ADT should be initiated as soon as possible before an attack of general and/or clinical stage advanced to delay resistance. A drilling should be associated with this hormone therapy as much as possible because of its gain on resistance.
