Enteric viral pathogens are responsible for numerous epidemics associated with the consumption of fresh fruit and vegetable, whether raw or minimally processed. The aim of the present study was to assess agricultural practices and the presence of adenovirus (AdV) in fruits and vegetables, manure and irrigation wastewater sampled in the urban and peri-urban perimeters of Ouagadougou. A total of 286 samples including 30 lettuces, 42 tomatoes, 30 carrots, 30 strawberries, 74 manures and 80 wastewater samples were collected from four market garden sites in and around Ouagadougou. Nested PCR was performed with specific primers to detect adenoviruses (AdVs). A face-to-face survey was carried out using a questionnaire on market garden production practices. Overall, adenoviruses prevalence was 5.9% [IC95, 3.2% - 8.7%] in all samples analyzed. It was specifically 7.14% (3/42) from tomatoes, 6.7% (2/30) from lettuces, 20% (6/30) on strawberries and 7.5% (6/80) in irrigation water. The survey showed that irrigation water came from untreated sources (dam, well, canal) and then 52% of farms used untreated manure. No farms have implemented measures to limit access by domestic and wild animals. This work shows the presence of human adenoviruses in surface irrigation water and fresh produce, which is of concern when fresh produce is consumed raw. To reduce the public health risks associated with consuming these foods, it is essential to follow good hygiene and cultivation practices.

Background: HIV in pregnant women presented a risk of transmission to newborns. This study was to determine HIV prevalence among pregnant women in the birthing rooms and give antiretrovirals to women infected and their newborns. Methods: A preliminary study was conducted from 2013 to 2015 at the Mother and Child Hospital. Pregnant women were counseled and tested for HIV-antibody according to the national algorithm using Determine HIV 1 & 2 and Immunocomb II Bispot HIV1 & 2. The women screened HIV-negative during the prenatal consultation and who accepted a second test were screened in the birth room. The data collected were processed using the Access Microsoft office 16 and SPSS software version 18. Results: A total of 6080 pregnant women were tested before and in the birth room. Of these, 5943 (97.4%) were detected as HIV-negative and 159 (2.6%) were HIV-positive. Of the 5943 with HIV-negative status, 1333 accepted the second test in the birth room, 10 of which have become HIV-positive. The rate of seroconversions was 0.75%. Conclusion: This study determined the prevalence of HIV in pregnant women. The result reveals the importance and necessity of repeating the screening test in the birth room because of the possibility of seroconversion or new infection during pregnancy.

Introduction: Pesticides are currently an essential component of agricultural production techniques for controlling pests and weeds. In Burkina Faso, non-compliance with good practice in the use of pesticides poses a real health problem for the population. This study examines the health risks associated with pesticide management in rice-growing areas. Material and Methods: A field survey was conducted in Bama, involving farmers, focusing on their socio-demographic characteristics, pesticide usage, and health effects. Cholinesterase levels were measured in subsample of farmers using a portable device. Data were analysed using Microsoft Excel, calculating means and percentages for various practices. Health consultations, protection methods, and pesticide management were studied. Erythrocyte acetylcholinesterase activity was compared before and after treatment. Data were categorised into classes based on inhibition levels, and correlation analyses determined relationships between variables such as age, years of experience, and cholinesterase activity. Results: The results indicate that rice cultivation is mainly carried out by a fairly young population, with nearly 63% being under the age of 50. Common poor practices in pesticide use include improper storage and reuse of leftover pesticides. Seven types of pesticides were identified, including organophosphates such as glyphosate, which was used in 26.7% of cases. This organophosphate has resulted in class B poisoning, causing a 30% - 50% reduction in erythrocyte cholinesterase activity. The health effects of pesticide use are felt by agricultural farmers through various symptoms of poisoning. Conclusion: To reduce the occurrence of pesticide poisoning, it is essential to launch information and awareness campaigns among the population and farmers to promote safe practices in pesticide use in Bama, Burkina Faso.

Gastroenteritis constitutes a group of diarrheal diseases of infectious origin, responsible for absenteeism from work, morbidity and mortality, especially among aged people. This study aimed to evaluate the antibacterial activity of Mitragyna inermis extracts on the in vitro growth of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa involved in gastroenteritis. Phytochemical screening was carried out using two distinct methods. The detection of phytochemical compounds by tube coloring and chromatography on a thin layer of silica gel. The sensitivity of organisms was evaluated by the agar well method. The dilution method in liquid medium coupled with spreading on Mueller Hinton agar helped determine the CMB/MIC activity ratios. The investigations show that the extract has the best extraction yield (75.86% ± 0.20%) compared to the aqueous macerated (61.8% ± 0.08%) and decocted (66.6% ± 0.12%). These extracts contain several phytochemical compounds such as flavonoids, polyphenols, tannins, alkaloids, saponosides, coumarins and sterols and terpenes. These substances are endowed with biological activities and could be at the origin of antibacterial activity observed with M. inermis extracts. The analysis of antibacterial activity showed that the germs are sensitive to the extracts with inhibition diameters ranging from 8.30 ± 0.53 to 17.87 ± 0.58 mm. The ethanolic extract was the most active with diameters varying from 15.07 ± 0.62 to 17.87 ± 0.58 mm on all the germs tested. E. coli and S. aureus were the most sensitive germs to the extracts. P. aeruginosa was the least sensitive germ. Activity reports indicate that the extracts exert bactericidal activity on E. coli and S. aureus but bacteriostatic activity on P. aeruginosa. These results justify the use of M. inermis leaves in a traditional environment to treat gastroenteritis.

Introduction: Physiotherapy is an integral part of the non-drug treatment strategy for rheumatological conditions. The evidence for its effects is not formal. The objective was to evaluate the impact of physiotherapy in the management of rheumatological disorders. Methods: 6-month case-control study (December 15, 2021 to June 20, 2022) at Ignace Deen University Hospital (Conakry). Patients with rheumatological disease who received drug therapy and physiotherapy were included in the case group. Age- and sex-matched controls had rheumatological conditions, treated without physiotherapy. The evaluation questionnaires were used: WOMAC (osteoarthritis), EIFEL (low back pain), NDI (neck pain), SPADI (shoulder). Patients with heart failure, respiratory failure and/or skin infection were not included. Results: We collected 773 patients (389 cases and 384 controls) with a mean age of 53.8 years ± 12.2 with female predominance (56.8%). Patients were mainly followed for osteoarthritis (65.2%). Rheumatological conditions managed were knee-based (119;30.6%), lumbar spine (220;56.6%), shoulders (27;6.9%) and cervical spine (23;5.9%). For an average duration of 53.4 ± 12.2 minutes per session, patients had benefited from a median of 19 physiotherapy sessions. After 3 months, the baseline mean VAS of 6/10 improved to 2.2 ± 1.6 for cases and 5.7 ± 1.2 for controls. Functional capacity was improved (WOMAC: 41.8 ± 22.7 vs. 18.3 ± 7.3). The satisfaction of patients treated with physiotherapy was 20 times higher than in controls. Conclusion: Physiotherapy performed in the management of rheumatological conditions significantly reduced pain and improved functional capacity.

Introduction: Coagulase-negative staphylococci (CoNS) are currently recognized as genuine pathogens. However, little is known about the resistance and virulence genes that explain their pathogenicity in hospitals in Cte d'Ivoire. The aim of this study was to contribute to the genotypic identification of resistance and virulence genes in CoNS isolated from blood cultures at the University Teaching Hospital (CHU) of Bouak, in order to improve patient management. Material and Methods: This was a descriptive study conducted from September to December 2023. The CoNS isolates studied came from the collection of strains isolated from blood cultures of febrile patients hospitalized or attending consultations at the CHU of Bouak. The strains were analyzed using conventional simplex PCR. Results: Of the 45 isolates analyzed, 46.7% carried both the aacA-aphD and tetK genes and 40% carried the mecA gene. With regard to virulence genes, only the LukS-PV gene was observed in S. epidermidis and S. haemolyticus isolates. Conclusion: The high prevalence of CoNS isolates carrying the mecA gene and the presence of virulence genes observed in this study give cause for concern in hospitals. It is important to develop comprehensive surveillance strategies against nosocomial and multi-resistant infections at the CHU of Bouak.

Dyslipidemia is a disorder where abnormally lipid concentrations circulate in the bloodstream. The disorder is common in type 2 diabetics (T2D) and is linked with T2D comorbidities, particularly cardiovascular disease. Dyslipidemia in T2D is typically characterized by elevated plasma triglyceride and low high-density lipoprotein cholesterol (HDL-C) levels. There is a significant gap in the literature regarding dyslipidemia in rural parts of Africa, where lipid profiles may not be captured through routine surveillance. This study aimed to characterize the prevalence and demo-graphic profile of dyslipidemia in T2D in the rural community of Ganadougou, Mali. We performed a cross-sectional study of 104 subjects with T2D in Ganadougou between November 2021 and March 2022. Demographic and lipid profiles were collected through cross-sectional surveys and serological analyses. The overall prevalence of dyslipidemia in T2D patients was 87.5% (91/104), which did not differ by sex (P = .368). High low-density lipoprotein cholesterol (LDL-C) was the most common lipid abnormality (78.9%, [82/104]). Dyslipidemia was associated with age and hypertension status (P = .013 and.036, respectively). High total and high LDL-C parameters were significantly associated with hypertension (P = .029 and .006, respectively). In low-resource settings such as rural Mali, there is a critical need to improve infrastructure for routine dyslipidemia screening to guide its prevention and intervention approaches. The high rates of dyslipidemia observed in Gandadougou, consistent with concomitant increases in cardiovascular diseases in Africa suggest that lipid profile assessments should be incorporated into routine medical care for T2D patients in African rural settings.

Connective tissue diseases (CTDs) are Autoimmune diseases (AIDs) characterized by the appearance of autoantibodies, which are diagnostic markers. Investigations of these autoantibodies play a major role in the management of several autoimmune diseases. The objective of this study was to describe the profile of anti-ENA antibodies according to the clinical symptoms of mixed CTDs in Conakry teaching Hospital. We performed a cross-sectional study during six months. A total of 20 patients was recruited and we measured antibodies using the ELISA technique. The mean age of our patients was 36.5 years, with a predominance of females. Cutaneous and rheumatological signs were the main clinical manifestations. SLP was the most frequent CTDs;the threshold of ENA antibodies positivity was higher in scleroderma with and SLP. Anti-ENA identification reveals the frequency of anti-SSA (83.33%), anti-U1RNP (66.66%) and anti-histone (50%) antibodies. Antinuclear antibodies (ANA) react with various components of the cell nucleus. Their detection is of major interest in the diagnosis of CTDs. Our results highlight the importance of determining the specificity of these antibodies to guide differential diagnosis.

Every woman has the right to receive satisfactory quality prenatal care in reproductive health. Giving a life while remaining alive and without sequelae must be the slogan of any gynecologist - obstetrician and midwife, as well as any health worker. It was a descriptive cross-sectional study dealing with the evaluation of the quality of prenatal consultations at the Kadiolo referral health center (or RHC). Adevis Donabedian’s model for assessing the quality of care and services served as a benchmark. According to Donabedian quality means good technical care, with good interpersonal relationships, and adequate and comfortable premises. This study took place from April 24 to December 04, 2017 and aimed to assess the current level of the quality of prenatal consultations at the Kadiolo referral health center, to study the structures in place including infrastructure and personnel, to specify the procedures and to determine their results. This work has permitted us to classify the RHC of Kadiolo at level III with 85%, which means that the references evaluated were satisfactory, with the level of 75% to 94%. In terms of structure, a pricing system was deemed affordable by the opinion of pregnant women. The analysis of the level of the human dimension revealed that the health center was level III. The pregnant women were satisfied with the reception which was good in 76% of the cases, as well as with the quality of the respect of the privacy in 96% and confidentiality in 95%. Despite the satisfaction of pregnant women, gaps remain to be filled in concerning the quality of the services received at the Kadiolo referral health center so as to reach level IV.

Complications of Circumcision: Epidemiological, Anatomo-Clinical and Therapeutic Aspects

引用

Open Journal of Urology 2023年第10期13卷 433-440页

作者： Aboubacar traore Issa Thiam Ousmane Sow Modou Sene Ndiath abdoulaye Sow Yaya Urology Department Regional Hospital of Saint-Louis Saint-Louis Senegal

Circumcision refers, in its most widespread form, to the total or partial removal of the foreskin, leaving the glans exposed. It is a ritual practice imposed by Mosaic law for Israelites, a tradition for Muslims, a rite of passage to adulthood for many people of Africa and the East. Circumcision is also a widely used therapeutic surgical procedure for a number of balanopreputial affections. The aim of this study was to list cases of circumcision complications received in a urological hospital (CHR Saint Louis) and to analyze their epidemiological, anatomo-clinical and therapeutic aspects. Patients and methods: This was a retrospective, descriptive study of circumcision complications, carried out in the urology department of the Saint Louis regional hospital in Senegal over a 5-year period (January 1, 2013 to December 31, 2017). Results: Thirty-three (33) complications of circumcision were collated. The mean age of patients was 7.63 years [9 months - 16 years]. Duration of time for Consultation varied according to the type of complication, with an average of 1.6 years [1 day - 10 years]. Penile granuloma accounted for 36.3% of the complications (n = 12), local infection for 30.3% (n = 10) and urethro-cutaneous fistula for 18.2% (n = 6). For six patients with urethro-cutaneous fistula, we performed urethro-cutaneous splitting in 5 patients, while the same complication necessitated urethroplasty in another patient. We noted five cases of verge plasty for verge granuloma, one glan reimplantation and one glan plasty for the two patients with glans amputation. Conclusion: Circumcision is a medical procedure widely practised throughout the world for medical, cultural and aesthetic reasons. In Africa, the lack of health coverage and the shortage of doctors explain why this surgical procedure is so common. In Senegal, circumcision is still carried out in the majority of cases by paramedical staff, which explains the high rate of complications.
