Background: The welding trade includes many industrial activities in both the formal and informal sectors. Workers in this professional environment do not have access to individual and collective means of protection adapted to the activity, which exposes them to the dust emitted during their activity and therefore contributes to increasing the risk of developing respiratory disorders in this population. Objective: Our study aimed to evaluate the ventilatory function of metal welders in the city of Dakar. Method: This was a comparative study based on the analysis of the spirometric parameters of metal welders working in the city of Dakar (Senegal) with those of a control group of the same kind, selected from the general population. Measurements of forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and maximum mid expiratory flow (MMEF) were measured. Results: A total of 75 men between the ages of 19 and 61 were recruited and divided into two groups (43 controls and 32 welders). The welding population had more frequent distal and central obstructions and pulmonary restriction compared to the control group. The metals most commonly used by welders were aluminum for welders who had an obstruction, while for those who had a restriction, iron was the most used metal. Signs of metal fever were frequently found in welders, especially those with ventilatory disorders. Conclusion: The prevalence of respiratory disorders observed is close to that observed in industrial environments, where exposure levels are the highest. The lack of personal protective equipment could also be a significant risk factor in the development of these disorders.

Introduction: Otorhinolaryngological (ORL) and cervicofacial traumas encompass injuries affecting the neck, face, and ORL region, resulting from external influence. The objective of this study was to conduct an epidemiological and clinical analysis of ORL and cervicofacial injuries observed in victims of road accidents treated at the Otorhinolaryngology (ORL) department of the Regional Hospital of Mamou. Materials and Methods: This prospective and descriptive study was conducted over a period of 12 months, from January 1st to December 31st, 2021, within the Otorhinolaryngology (ORL) department of the Regional Hospital of Mamou. It included patients hospitalized for ORL and/or cervicofacial traumas resulting from road accidents during the study period. Results: A total of 348 cases were included, representing 36.22% of all traumas related to road accidents (AVP) within the Regional Hospital of Mamou. The average age of the patients was 26.44 years, with a sex ratio of 3.83, favoring males. The dominant socio-professional category was students, encompassing 32.47% of cases. Road accidents were mainly associated with motorcycle use (31.32% motorcycle-to-motorcycle, 24.43% motorcycle skidding, 13.51% motorcycle-pedestrian). Facial region injuries were the most common, accounting for 69.03% of cases, followed by rhinological injuries (17.28%) and otological injuries (13.69%). Associated injuries were predominantly closed head traumas (52.55%) and lower limb fractures (20.41%). Imaging was underutilized. Regarding surgical interventions, reconstructive surgery was the most predominant, accounting for 52.51% of cases, with a management timeframe of 30 minutes to 12 hours for 99.72% of patients. Conclusion: Road traffic accidents remain a serious public health issue, primarily affecting young males. Emphasis should be placed on road safety measures to reduce the frequency of these accidents.

Open Journal of Gastroenterology 2024年第3期14卷 93-98页

作者： Sanra Déborah Sanogo Kadiatou Doumbia Hourouma Sow Moussa Younoussou Dicko Youssouf Oumarou abdoulaye Berthé Sabine Drabo Luc Sidibé Makan Siré Tounkara abdoulaye Maiga Ouatou Mallé Ganda Soumaré Anselme Konaté Moussa Tièmoko Diarra Hepato-Gastroenterology Department CHU Point G Bamako Mali Hepato-Gastroenterology Department CHU Gabriel Touré Bamako Mali Department of Internal Medicine Centre Hospitalier Universitaire Communautaire de Bangui Bangui Central African Republic

Infection with the defective hepatitis D virus (HDV) co-infects or superinfects a patient carrying hepatitis B virus (HBV). Delta virus infection is relatively common. The seriousness of infection with the hepatitis D virus (HDV), a virus defective in a patient carrying the hepatitis B virus (HBV), lies in its aggravating effect on the associated viral hepatitis B. Our aim was to study the serological profile of HDV in HBsAg-positive patients. As this study was fragmentary, we initiated this study with the aim of investigating the serological profile of HDV in HBsAg-positive patients. This was a descriptive and analytical cross-sectional study that ran from March 2019 to February 2020, a 12-month period. It focused on the population of patients seen and screened positive for HBsAg. We obtained a frequency of 10%. The mean age of our patients was 41.8 ± 13.09 years. The sex ratio was 4.5. VHD RNA was detected in 50% of patients. In 100% of cases, the presence of VHD RNA was associated with advanced fibrosis according to the APRI score, but without any statistically significant link. All HBV-infected patients should be screened for anti-HDV Ac. HDV infection leads to rapid progression to complications of liver disease.

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.

XRF and EDX analyses were carried out on 18 batches of representative raw samples to determine the distribution of major chemical elements in the petroleum source rocks of Donga and Yogou formations of Termit sedimentary basin. The chemical composition of these formations is dominated by silicon (Si), aluminum (Al) and iron (Fe). This is consistent with the oxide composition, which is also dominated by silicon oxide (SiO2), aluminum oxide (Al2O3) and iron monoxide (FeO). No less important chemical elements are calcium (Ca), potassium (K), sulfur (S), titanium (Ti), magnesium (Mg), manganese (Mn) and barium (Ba), as well as some of their oxides. All these major chemical elements are carried by silicate detrital minerals associated with pyrite and goethite and/or clay minerals such as kaolinite and interstratified illite, smectite and chlorite. This trend is illustrated by the values of the Si/Al and SiO2/Al2O3 ratios.

作者： Alimou Diallo Thierno Oumar Diallo Alpha Oumar Barry Ibrahima Bah abdoulaye Bobo Diallo Oumar Raphiou Bah Urology Department of the Hospital of the Sino-Guinean Friendship Faculty of Health Sciences and Technologies Gamal Abdel Nasser University of Conakry Conakry Guinea Urology Department of National Ignace Deen Hospital Faculty of Health Sciences and Technologies Gamal Abdel Nasser University of Conakry Conakry Guinea

Objective: Describe the psychosocial aspects of male infertility at the hospital of the Sino-Guinean Friendship. Patients and method: It is a prospective study of a descriptive type covering a period of 6 months. The study covered 17 patients, all received for a desire to conceive after at least one year of regular sexual intercourse without contraception. The data were collected from patient interviews using a pre-established questionnaire. Results: The average age of the patients was 32.07 years with extremes of 23 years and 42 years. During this study, 64.70% of patients were no longer participating in community ceremonies. The patients’ relationships with their spouse and family deteriorated in 52.94% and 47.06%, respectively. Conversely, relations with the family of origin remained unchanged in 70.59 percent of cases. The reduction in economic activity was by 13 patients (76.48%). Conclusion: Male infertility causes a real psychic earthquake in men with its corollaries of negative feelings. The rather complex moral repercussions of male infertility affect not only the individual, his/her partner, and family, but also economic activity.

Introduction: OSD is a growth osteochondrosis affecting the apophyseal cartilage of the anterior tibial tuberosity of the knee, 20 to 30% of young growing athletes suffer from this pathology, described by Osgood and Schlatter in 1903. Objective: To report 2 observations and review the literature. Observation 1: This was a 14-year-old Guinean teenager, Halpoular, living in Conakry, a right-handed footballer who presented with a painful swelling of the right knee that looked mechanical, whose father had HLA B27 positive ankylosing spondylitis. X-ray of the right knee showed fragmentation of the anterior tibial tuberosities, and ossicle with edema of the patellar tendons at stage 4 according to Ehrenbord and Lagergren (1961). Thus, the disease of OSD is retained, He received 120 mg of diclofenac, 20 mg omeprazole for 1 month and the cessation of sports activity, the evolution was favorably marked by the regression of pain. Observation 2: A 16-year-old girl, initials M.L.T, Guinean, residing in Coyah (Republic of Guinea), a handball player, consulted for intense pain (VAS: 8/10) in her knees after a violent shock received when she hit the post. The physical examination found a painful, soft swelling at the anterior tibial tuberosity of the right knee, the rest of the examination was normal. The X-ray of the right knee shows fragmentation of the anterior tibial tuberosity, and ossicle with edema of the patellar tendon at stage 4 according to Ehrenbord and Lagergren 1961, thus the OSD disease is retained, the treatment instituted was 120 mg of diclofenac, the cessation of sports activity which gives a good evolution (EVA at 2/10). Conclusion: OSD is a growth osteochondrosis affecting the apophyseal cartilage of the anterior tibial tuberosity of the knee in young growing athletes, resolving at rest.

Background: Type 2 diabetes is a metabolic disease characterized by chronic hyperglycemia. The latter plays an essential role in inflammation by stimulating the production of pro-inflammatory cytokines or by increasing their secretion by an oxidative mechanism. These cytokines control the hepatic synthesis of an inflammatory protein called C-Reactive Protein (CRP). High or average values of CRP would have a predictive value of cardiovascular diseases and type 2 diabetes. The relationship between low CRP values and the risk of developing type 2 diabetes and its cardiovascular complications is not sufficiently studied. The hsCRP could serve as a predictive biomarker of risk of onset, follow-up and prognosis for type 2 diabetes and its cardiovascular complications. To answer this problem, we conducted this study, the aim of which was to study the predictive role of hsCRP in the risk of occurrence of type 2 diabetes and its cardiovascular complications. Materials and Methods: This is a prospective and cross-sectional case-control study involving 200 participants including 100 control women and 100 women with type 2 diabetes (mean age was respectively 49.89 years ± 8.26 & 51.92 years ± 7.18;p = 0.066). The interviews were conducted on the basis of a questionnaire. Physical examination collected biometric data and cardiovascular constants. The biochemical parameters such as hsCRP were analyzed by an automated Abbott device. Results: We noted that hsCRP was significantly higher in type 2 diabetic subjects compared to control subjects (p (rho = 0.40, p systolic blood pressure (rho = 0.30, p = 0.003), diastolic blood pressure (rho = 0.28, p = 0.006), total body fat (rho = 0.48, p Conclusion: hsCRP has a prognostic value in the evaluation of cardiovascular risk. It seems to play an important role in the pathogenesis of type 2 diabetes mellitus and its cardiovascular complications. It could thus be considered as a biomarker for the screening, monitoring and prognosis of type 2

Consumers’ Perception and Knowledge of Food Additives in Senegal: A Pilot Study

引用

Open Journal of Applied Sciences 2024年第1期14卷 38-50页

Food safety has become a major concern for consumers, as well as a priority for regulatory authorities. Faced with the growing industrial and domestic use of food additives, many questions are being asked and concerns are being felt by consumers around the world. Consumer perception defines the acceptability or rejection of food products, and has an impact on consumption patterns and behavior. To assess the level of knowledge and perception of food additives, a pilot study was carried out on a sample of 200 people in Dakar and Saint-Louis. A questionnaire was used to assess the acceptance or rejection, use and impact of food additives by consumers in Senegal. The results revealed several aspects. On the whole, the people surveyed expressed great mistrust and even rejection of these substances added to food products. This consumer perception is shared throughout the world, as indicated in numerous surveys. It also emerges from this study that, although most consumers are aware of the existence of these additives and their uses in the home, they feel that the use of these substances in industrial production is too excessive. What’s more, consumers associate food additives with numerous pathologies such as cancer, diabetes, hypertension, stroke and even sexual impotence. For some of these indexed pathologies, scientific studies have reached the same conclusions, although controversy still persists. On the other hand, for some of the other adverse effects mentioned, no cause-and-effect relationship has been scientifically demonstrated. In these latter cases, it seems that negative communication, misinformation and misconceptions have a major influence on consumer perception of food additives.

Introduction: Infant and child morbidity and mortality linked to infections remain a major concern in both developed and developing countries. The general objective was to determine the characteristics of hospital morbidity and mortality linked to infectious pathologies in the pediatric department of the King Baudouin hospital center in Dakar. Methods: This was a retrospective, descriptive and analytical study focusing on children hospitalized from January 1, 2018 to December 31, 2021 in the pediatric department of the King Baudouin hospital center in Dakar. Results: During the study period, 1474 children were hospitalized for an infectious pathology in the pediatric department. The sex ratio was 1.48. Children aged between one and twelve months represented 34.12%. Morbidity due to respiratory and digestive infections was 42.33% and 33.45%, respectively. Pediatric hospital mortality was 0.75% with a predominance noted in infants between 1 and 12 months (55.86%). Respiratory, digestive infections, sepsis and neurological infections were the main causes of death. Factors associated with mortality were age (1 to 12 months) with p Conclusion: Reducing infant and child mortality linked to infectious diseases remains a crucial challenge to address for improving children’s health. Early detection of related signs, prevention of infections, and adequate care and monitoring of infants and children can contribute to this reduction.
