A Panorama of the Urological Diseases at the Former Military Teaching Hospital of Cotonou

Background: Urological care has been advancing quickly over the last ten years in Benin. In order to conveniently support that trend towards better urological care standards, decision-makers need sound data on urological diseases in the country. Objective: To determine the prevalence of urological diseases in the former Military Teaching Hospital of Cotonou. Patients and Method: We retrospectively collected the urological diseases that the institution had managed from January 2012 to December 2020. We used Excel© 2010 and SPSS© to analyze the collected data. Results: 4244 patients, i.e. 3717 males (87.58%) and 527 females (12.42%) were managed during the study period. The main diseases diagnosed were benign prostatic hyperplasia (32.61%, n = 1384), erectile dysfunction (10.44%, n = 443), chronic prostatitis (5.94%, n = 252), prostate cancer (4.03%, n = 171), and ejaculatory disorders (3.44%, n = 146). In patients ≤ 15 years, predominant diseases were peritoneal vaginal canal (15.9%, n = 43), circumcision (15.6%, n = 42), testicular dystopia (10.7%, n = 29), hydrocele (7.8%, n = 21), and hypospadias (5.6%, n = 15). Wilms tumor (1.9%, n = 5) was the first cancer, testicular (0.4%, n = 1) and para-testicular (0.4%, n = 1) tumors were the next. In patients > 15 and ≤40 years, the main diseases were infertility (14.1%, n = 189), chronic prostatitis (12.9%, n = 173), erectile dysfunction (10.1%, n = 135), ejaculatory disorders (6.2%, n = 83), genital infections (6.2%, n = 83) and urinary stone (4.9%, n = 66). The first cancer was kidney cancer (0.97%, n = 13) followed by bladder cancer (0.3%, n = 4) and testicular tumor (0.3%, n = 4). In patients >40 years, the most prevalent diseases were BPH (52.0%, n = 1370), erectile dysfunction (11.7%, n = 308), prostate cancer (6.5%, n = 171), inguinal hernia (5.1%, n = 134), and urinary stone (3.9%, n = 102). Prostate cancer is the first cancer;the next were bladder (0.95%, n = 25) and kidney (0.68%, n = 18) cancers. Conclusion: Benign prostatic hyperplasia and urological cancers (prostate, bladder and kidney cancers) were the main urological diseases at the former Military Teaching Hospital of Cotonou. Urological malformations and Wilms tumor were the main diseases in the children.

Clinical Application of Percutaneous Nephrostomy in Some Urologic Diseases

Percutaneous nephrostomy was applied in some other urologic diseases and the efficacy was evaluated. Percutaneous nephrostomy for percutaneous nephrolithotomy （PNL） was performed in patients with various renal, perinephric and bladder diseases （n=79）. The tract establishment, operation duration and complications were observed and the efficacy was assessed. The results showed that the tracts were successfully established in 79 cases. The operation lasted 4–20 min. 12F–16F single tract was established in nephrohydrop patients and 16F–20F single or multiple tracts were established in patients with pyonephrosis, renal cortical abscess, renal cyst and perinephric abscess. During dilation, no leakage of liquor puris was noted. Establishment of 18F single tract was achieved in one urinoma patient. In two patients with foreign body in kidney, the foreign bodies were removed via established 14F single tract. 18F tracts were established in 2 patients with bladder contracture, which was followed by the placement of 16F balloon urethral catheter for drainage. No complications, such as massive bleeding, intestinal injury and spreading of infection took place in our series. All the patients were followed up for 2–12 months. No long-term complications such as dropping of drainage tube occurred. It is concluded that as a minimally invasive technique, percutaneous nephrostomy has the advantages of convenience, simplicity and causing less complications and can be used for various urologic diseases.

Epidemiological Aspects of Female Urological Diseases, at the National University Teaching Hospital H. K. Maga of Cotonou from 2008 to 2017

Most urological conditions are represented by male disorders. Analyzing certain epidemiological aspects of female urological disorders at the National University Teaching Hospital of Cotnou, will allow us objectively to have reliable data to optimize the urological management of women. Patients and Methods: This was a retrospective, analytical and descriptive study that was conducted at the CNHU-HKM over a 10-year period from January 2008 to December 2017 on the epidemiological aspects of female urological diseases from the study of patient records. The variable studied was: the age, the profession, the year of admission, the organ affected, and the type of pathology. The confidentiality of the data has been ensured. Results: Female urological disorders over 10 years accounted for 9.62% of all patients received in Urology Department. The age group greater than 50 years was the most common at 31.34%. Traders and housewives were the most numerous (39.93% and 14.55%). Bladder diseases were the most frequent (51.50), dominated by vesico-vaginal fistulas (29.85%). In addition to fistulas, tumoral affections were most prevalent at 27.99% followed by infectious diseases at 8.21%. The lithiasic affections were infrequent at 6.72%. Conclusion: Female urological conditions are infrequent but not negligible, dominated by vesico-vaginal fistulas and tumors in the context of developing countries. The specific evaluation of each pathology group can help optimize management.

Daily activities and training experiences of urology residents during the coronavirus disease 2019 pandemic in Indonesia: A nationwide survey

Objective:To explore the impact of the coronavirus disease 2019(COVID-19)pandemic on the training experiences of urology residents in Indonesia.Methods:A cross-sectional study using a web-based questionnaire(SurveyMonkey)involved all registered urology residents in Indonesia.The questionnaire was structured in Bahasa Indonesia,composed of 28 questions,and divided into three sections:demographic characteristics,current daily activities,and opinions regarding training experiences during the COVID-19 outbreak.The survey was distributed to all respondents via chief of residents in each urology center from May 26,2020 to Jun 2,2020.Results:Of the total 247 registered urology residents,243 were eligible for the study.The response and completeness rate for this study were 243/243(100%).The median age of respondents was 30(range:24e38)years old,and 92.2%of them were male.Among them,6(2.5%)respondents were confirmed as COVID-19 positive.A decrease in residents’involvement in clinical and surgical activities was distinguishable in endourological and open procedures.Most educational activities were switched to web-based video conferences,while others opted for the in-person method.Smart learning methods,such as joining a national or international speaker webinar or watching a recorded video,were used by 93.8%and 80.7%of the respondents,respectively.The respondents thought that educational activities using web-based video conferences and smart learning methods were effective methods of learning.Overall,the respondents felt unsure whether training experiences during the COVID-19 pandemic were comparable to the respective period before.Conclusion:The COVID-19 pandemic negatively affected urology residents’training experiences.However,it also opened up new possibilities for incorporating new learning methodologies in the future.

The impact of the cor on avirus disease 2019 Checkfol pandemic on elective urological procedures in Australia

Objective:To investigate the changes in elective private urological procedures in Australia during the coronavirus disease 2019 pandemic.Methods:Data were extracted from publicly available datasets from Medicare Ben efits Schedule using item nu mbers assig ned to each comm only performed urological interve ntion.These procedures were divided into three groups:Oncological therapeutic,diagnostic,and non-oncological therapeutic procedures.A smoothing model,based on the historic procedure numbers from 2017 to 2019,was used to forecast monthly number of procedures performed in each category between January 2020 and June 2020.These forecasted models were compared with reported figures.Results:A total of 108169 procedures were performed between January 2020 and June 2020 based on the Medicare Ben efits Schedule item nu mbers listed.There was a sign ifica nt reducti on(perce nt-age cha nge)in total procedures performed in April 2020(22.6%,95%con fide nee in terval[CI]:-28.7%to-15.4%)and May 2020(-33.2%,95%CI:-37.5%to 28.3%).There was a significant reduction in oncological therapeutic,non-oncological therapeutic,and diagnostic procedures performed in April 2020 and May 2020(p<0.05).These nu mbers did not in elude procedures performed in public sector.Conclusion:There was a significant reduction in total urological procedures(including diagnostic,oncological,and non-on cological)performed in mon ths of April 2020 and May 2020 during time of federal restrictions.Both public and private healthcare sectors need to be supported in the up-comi ng mon ths to preve nt further delays in treatme nt and poorer clinical outcomes.

Microbiological Quality of Drinking Water and Prevalence of Waterborne Diseases in the Gaza Strip, Palestine: A Narrative Review

Water quality and occurrence of water-borne diseases in the Gaza strip are vivid examples for most developing societies. In recent years, the quality and quantity of groundwater, the only source of waters in the Gaza strip, have deteriorated markedly. A general rundown of the infrastructure and water distribution networks, in particular, the spread of cesspools, excessive use of pesticides and fertilizers, and improper treatment and disposal of wastewater remain major contributing factors to the continued deterioration in the water status in the Gaza strip. Without a doubt, the (Israeli)-Palestinian conflict had a clear negative impact on the water sector in the Gaza strip. Apparently, there is a dire need to adopt the WHO’s water safety plan in the management of Gaza’s water supply systems from catchment to consumer’s tap in order to maintain the sustainability and quality of water resources and prevent outbreaks of waterborne diseases. Therefore, this review has been prepared to highlight the overall picture of the water dilemma in the Gaza strip in the last years and in addition, to identify the sources, sorts, levels, and health risks of consequence to microbial contamination of water. The impact of political conflicts on the water sector in the Gaza strip also was reviewed. Furthermore, recommendations were formulated in order to assist and guide future researchers, stakeholders, and policymakers to avoid the more exacerbation of water contamination as well as to protect public health.

Microbiological Assessment and Antimicrobials’ Use in an Infectious Diseases Department in Mali

The use of antimicrobials without microbiological proof is frequent and contributes to the emergence of resistance. The aim was to identify the organisms isolated during laboratory examinations and the type of antimicrobials consumed by patients hospitalized to Infectious Diseases’ Clinic. This is a cross-sectional and analytical study, carried out from January 1 to December 31, 2017 in the Infectious Diseases Department of Point “G” Teaching Hospital in Mali. All biological specimens from patients during the study period were analyzed. In total, 322 patients benefited from microbiological test, with a mean age of 40.9 ± 12.2 years (range 15 and 74 years) with a sex ratio of 0.93. Only 5.6% of patients were HIV negative. In all participants, a total of 658 microbiological specimen were taken, 224 (34.0%) identified at least one pathogen including bacteria in more than a half of the cases (58.5%). On the report of bacteriological analysis, the most frequently identified organisms were Mycobacterium tuberculosis (42.2%) mainly in sputum;Escherichia coli (24.2%) and Klebsiella pneumoniae (7.8%) commonly in urine and Gardnerella vaginalis (7.0%) exclusively in vaginal secretions. Candida albicans (5/8) and Cryptococcus neoformans (3/8) were the most common fungi while Plasmodium falciparum (96.4%) represented the parasite frequently found in blood. From a therapeutic standpoint, 1143 antimicrobials were prescribed to 322 admitted patients, i.e. 3.55 anti-infectives per patient. Antibiotics (excluding tuberculosis drugs), antiparasitics and antifungals represented respectively 46.2%;18.8% and 15.1% of anti-infectives. Antibiotic therapy was effective in 274 (85.1%) patients and among them, only 76 (27.7%) cases were based on microbiological evidence. Antibiotics are the most widely used antimicrobials in an infectious disease department. Empiric treatments are common but must be minimized by the search for microbiological evidence.

Urological manifestations and treatment of the primary systemic vasculitides

The primary systemic vasculitides(PSV) are a group of rare inflammatory disorders affecting blood vessels of varying size and multiple organs. Urological manifestations of PSV are uncommon. Testicular vasculitis is the most commonly reported finding and is associated with Polyarteritis Nodosa(PAN), Henoch-Sch?nleinPurpura(HSP), anti-neutrophil cytoplasm antibody associated Vasculitides(AAV), Giant Cell Arteritis(GCA) and Kawasaki disease. Prostatic vasculitis has been reported in association with GCA and AAV. Ureteric involvement has been noted in PAN, HSP and AAV. Other urogenital manifestations of PSV include genital ulceration and bladder dysfunction in Beh?ets Disease and haematuria which is commonly seen in many of the PSV. Finally, therapies used to treat the PSV, especially cyclophosphamide, are associated with urological sideeffects including haemorrhagic cystitis and urothelial malignancy. The aim of this review is to examine how the urological system is involved in the PSV. Each PSV is examined in turn, with a brief clinical description of the disease followed by a description of the urological manifestations and management. Identification of urological manifestations of PSV is important as in many cases symptoms may improve with immunosuppressive therapy, avoiding the need for invasive surgery. Additionally, patients who present with isolated urogenital PSV are at higher risk of developing subsequent systemic vasculitis and will need to be followed up closely.

Changes in the gut mycobiome in pediatric patients in relation to the clinical activity of Crohn's disease

BACKGROUND Numerous studies have shown that in Crohn’s disease(CD),the gut microbiota is of great importance in the induction and maintenance of inflammation in the gastrointestinal tract.Until recently,studies have focused almost exclusively on bacteria in the gut.Lately,more attention has been paid to the role of intestinal fungi.AIM To study the gut mycobiome analysis of pediatric patients with CD(in different stages of disease activity)compared to healthy children.METHODS Fecal samples were collected from patients:With active,newly diagnosed CD(n=50);active but previously diagnosed and treated CD(n=16);non-active CD and who were in clinical remission(n=39)and from healthy volunteers(n=40).Fungal DNA was isolated from the samples.Next,next generation sequencing(MiSeq,Illumina)was performed.The composition of mycobiota was correlated with clinical and blood parameters.RESULTS Candida spp.were overrepresented in CD patients,while in the control group,the most abundant genus was Saccharomyces.In CD patients,the percentage of Malassezia was almost twice that of the control(P<0.05).In active CD patients,we documented a higher abundance of Debaryomyces hansenii(D.hansenii)compared to the non-active CD and control(P<0.05)groups.Moreover,statistically significant changes in the abundance of Mycosphaerella,Rhodotorula,and Microidium were observed.The analyses at the species level and linear discriminant analysis showed that in each group it was possible to distinguish a specific species characteristic of a given patient population.Moreover,we have documented statistically significant correlations between:D.hansenii and patient age(negative);C.zeylanoides and patient age(positive);C.dubliniensis and calprotectin(positive);C.sake and calprotectin(positive);and C.tropicalis and pediatric CD activity index(PCDAI)(positive).CONCLUSION Mycobiome changes in CD patients,and the positive correlation of some species with calprotectin or PCDAI,give strong evidence that fungi may be of key importance in the development of CD.

Evidence for the involvement of infectious agents in the pathogenesis of Crohn's disease

Many advances have been made in the understanding of Crohn’s disease (CD) pathogenesis during the last decade. CD is currently seen as a predominantly T-lym-phocyte-driven disease characterized by the presence of a complex cocktail of interacting cytokines, chemokines and other mediators produced by a variety of cell types. Prevailing theories of CD pathogenesis suggest that patients’ T-lymphocytes are inappropriately activated in the setting of an immune imbalance, which is itself caused by an unfortunate confluence of genetic and en- vironmental factors. The T-cell response then leads to the chronic inflammation characteristic for the disease. Various environmental factors may play a role in the development of CD, but microbes are most consistently implied. This theory is based on epidemiological, clinico- pathological, genetic and experimental evidence. Despite the abundance of arguments for the implication of bac-teria in the aetiopathogenesis of CD, the precise role of bacteria in this disease still remains elusive. Three not necessarily mutually exclusive theories have been pro- posed: (1) an unidentified persistent pathogen; (2) an abnormally permeable mucosal barrier leading to exces-sive bacterial translocation; and (3) a breakdown in the balance between putative "protective" versus "harmful" intestinal bacteria ("dysbiosis"). At present, one cannot exclude with certainty any of these three proposed hy-potheses; they may all apply to CD to a certain extent.

Use of intralesional collagenase in the treatment of peyronie's disease: A review

AIM:To review the relevant literature in an effort to examine the body of evidence available to date.METHODS:Ovid MEDLINE search database was queried using MeS H terms"penile induration","peyronie’s disease","Collagenases"and"Collagenase"using various permutations.No temporal parameters were employed.RESULTS:In all,5 relevant clinical trials were isolated from 34 results.These trials were analyzed using the Oxford Centre for Evidence-Based Medicine criteria.They were further examined based on study design and methods;the primary and secondary outcomes were reviewed for treatment efficacy and collagenase-related side effects.CONCLUSION:Intralesional collagenase appears to be safe and effective in the non-surgical treatment of Peyronie’s disease.However,the data remains limited and further inquiries into the safety of collagenase,treatment standardization and standardized outcomesreporting remain necessary.Furthermore,studies comparing intralesional collagenase to alternative medical and surgical therapy will be important in guiding the future treatment decision process.

Reconstructive surgery in Peyronie's disease: What's new?

Surgical treatment of Peyronie's disease(PD) is still a challenge and a gold standard approach does not exist; however the main goal is to straight penile shaft, and to restore penetrative and coital capacity. The less invasive approach aims to correct curvature without intervening directly on the fibrous plaque while the more complex "corporoplasty" applies specific geometric criteria and uses different autologous and heterologous grafts. Each approach has its pros and cons and decisionmaking should be tailored to the individual patient's expectations. Other surgical options include different use of patches to cover the tunica albuginea defect, with the choice depending on the surgeon's personal experience. Despite the wide range of autologous(buccal mucosa, vein, dermis, etc.) and heterologous grafts(bovine pericardium, swine intestinal submucosa, porcine dermis, etc.) none currently represents the real "gold standard" because the data are extremely variable and frequently not representative. Several factors seem to favor buccal mucosa grafts over inert biocompatible materials: as vital tissue, buccal mucosa tends to heal rapidly, immediately integrating with the surrounding albuginea tissue. This translates into a more rapid resumption of spontaneous erections(after 3/4 d) and sexual activity and into a reduced risk of curvature relapse and erectile dysfunction after surgery. Another advantage of the buccal mucosa graft is its low cost. In conclusion, despite the recent development of some exciting new surgical techniques we are still unable to deliver a definitive take-home message about reconstructive surgery in PD because the majority of the studies reported insufficient data. However, since it is clear that major outcomes, besides the cosmetic result, are the patient's and partner's satisfaction and the economic impact of each technique, we recommend they be included among the outcome assessment parameters in further

Microbiota revolution:How gut microbes regulate our lives

The human intestine is a natural environment ecosystem of a complex of diversified and dynamic microorganisms,determined through a process of competition and natural selection during life.Those intestinal microorganisms called microbiota and are involved in a variety of mechanisms of the organism,they interact with the host and therefore are in contact with the organs of the various systems.However,they play a crucial role in maintaining host homeostasis,also influencing its behaviour.Thus,microorganisms perform a series of biological functions important for human well-being.The host provides the microorganisms with the environment and nutrients,simultaneously drawing many benefits such as their contribution to metabolic,trophic,immunological,and other functions.For these reasons it has been reported that its quantitative and qualitative composition can play a protective or harmful role on the host health.Therefore,a dysbiosis can lead to an association of unfavourable factors which lead to a dysregulation of the physiological processes of homeostasis.Thus,it has previously noted that the gut microbiota can participate in the pathogenesis of autoimmune diseases,chronic intestinal inflammation,diabetes mellitus,obesity and atherosclerosis,neurological disorders(e.g.,neurological diseases,autism,etc.)colorectal cancer,and more.
