Research background: Breast cancer remains a major public health problem, with a high number of new cases and deaths each year. However, despite advances in research to improve this disease, there is a high rate of late detection, leading to diagnosis at an advanced stage and a reduced chance of survival. Objective: The aim of this study is to identify the factors associated with late detection of breast cancer in women in Sub-Saharan Africa from 2014 to ***: This systematic review focuses on sub-Saharan Africa. Methods: We searched for articles in four databases (PubMed, Embase, Global-Health and CINAHL) between 2014 and 2020 and performed a narrative synthesis to organize and group the different factors associated with late breast cancer detection. Result: After reviewing 583 publications, 6 studies were selected, highlighting factors such as lack of awareness, knowledge gaps, difficulties in accessing health services and financial constraints associated with late breast cancer screening. The participants, who ranged in number from 20 to 1776, were mainly aged between 18 and 25, with a mean age of 25 years and 6 months. Conclusion: The analysis enabled us to identify various factors associated with late breast cancer screening. Collaboration between health professionals, community organizations and policy-makers is essential to foster an environment conducive to the prevention and early detection of breast cancer.

Aim: Evaluate the impact of MAGIC trial on gastric adenocarcinoma’s management in Africa. Method and methodology: It was about a review of literature on therapeutic aspects of gastric adenocarcinoma in the African area. We have taken a census of 21 articles including 2792 patients published between 1980 and 2013. We have distinguished articles published before 2006 (group 1) from those published after 2006 (group 2) to better understand therapeutic changes after that perioperative chemotherapy has become a standard in gastric adenocarcinoma’s management. Results: Surgery remains in Africa the first and practically the only treatment weapon in gastric adenocarcinoma: 46% to 92% people in the 1st group and 65% to 100% people in the 2nd group underwent surgical procedures. Perioperative chemotherapy takes longer to be part of therapeutic habits (0.18%). Factors related to patients such alteration of general state with a WHO performance status superior to 2 in 72% of cases, the lack of financial accessibility to anticancerous drugs explains partly the non-use of perioperative chemotherapy. This is also due to factors peculiar to our sanitation structures which don’t have enough cancer specialists. So we noticed that MAGIC trial is simply ignored in certain studies. The lack of adoption of perioperative chemotherapy explains with delayed diagnosis the low survival of patients in the African area. Conclusion: MAGIC trial practically has no effect on therapeutic behavior yet comparatively to gastric adenocarcinoma in Africa. The insurance particularly relies on surgery only until now. However, it might enable us to improve gastric adenocarcinoma’s survival rates.

Background: We conducted this study to identify factors associated with the onset and reversibility of chemotherapy-induced amenorrhea in Yalgado Ouédraogo Teaching Hospital of Ouagadougou. Methods: A historical cohort study was performed and covered the period from 1 January 2014 to 31 July 2015. No menopausal patients managed for a histologically confirmed breast carcinoma and having benefited from chemotherapy were included in the study. Logistic regression analysis was used to determine the factors associated with the occurrence of chemotherapy-induced amenorrhea as well as its reversibility. Results: Seventy patients were included. The mean age was 38.5 years. Thirteen patients were obese and 19 (40.4%) had their menarche after age of 15 years. Adjuvant chemotherapy was administered to 31 patients while 12 had received neoadjuvant chemotherapy. Sequential chemotherapy with an anthracycline and a taxanetherapeutic protocol was the most used. Forty-seven patients had a chemotherapy-induced amenorrhea. The risk of having a chemotherapy-induced amenorrhea increases by 25% for each additional year of age at diagnosis of cancer (p = 0.0001). Obesity and menarche after age 15 were found to be protective factors. After adjusting these variables together, age, obesity, and age at menarche were factors independently associated with the occurrence of the chemotherapy-induced amenorrhea. The reversibility was effective in 11 cases (37.9%) and especially concerned patients younger than 40 years (p = 0.03). Conclusion: Age is the primary risk factor. Reliable markers of ovarian function need to be developed to better select fertility conservation protocols.

Introduction: Transanal evisceration of small bowel is an extremely rare condition that can occur spontaneously or after trauma. Objective: To report a case of Transanal evisceration of small bowel to describe the circumstances of occurrence and our therapeutic attitude. Observation: An 80-year-old female patient was received at the visceral Emergency of University Hospital Yalgado Ouédraogo for the outcome of the small intestine by the anus with the waning of a defecation effort. The physical examination of the patient accustomed to evacuation purgation noted, eviscerated the small bowel through the anus, edematous but viable. The preoperative laboratory tests were normal. In emergency, under general anesthesia, a laparotomy was possible to objectify the incarceration of intestinal loops through linear perforation of 5 cenimeter from the anterior surface of the rectosigmoid hinge. We conducted an ileo-ileal resection anastomosis, a suture rectosigmoid breach and anal extraction of small bowel incarcerated measuring 200 centimeter. The evolution was simple. Conclusion: The weakening of the rectal mucosa by repeated purges has certainly been the contributory factor. The surgical treatment must be precocious to avoid extensive intestinal resection.

Purpose: To study the epidemiological and anatomopathological aspects of urological cancers in Burkina Faso from 1988 to 2018. Patients and Methods: A cross-sectional, retrospective and descriptive study of histologically confirmed cancers that are collected from pathological anatomy laboratory records. The aspects studied were age, sex, location and histological type. Results: A total of 2204 cases of urological cancer were collected. The predominance was male with a sex-ratio of 9.6. The average age was 63.32 years. We found 1602 cases of prostate cancer (72.68%), 361 cancers of the bladder and excretory tract (16.4%), 180 cancers of the kidney (8.16%), 33 testis cancers (1.5%) and 28 penile cancers (1.3%). The predominant histological type of prostate cancer was adenocarcinoma (96.4%) with a Gleason score 7 in 30.4% of cases. Bladder cancer consisted of 50% epidermoid carcinomas. Kidney cancer was mostly nephrotoblastomas with 42.2% of cases. We noted 42.4% of seminomas among testis cancers and 89.3% of epidermoid carcinomas within penile cancers. Conclusion: The incidence of urological cancers is increasing in Burkina Faso. These cancers occur at a relatively advanced age with male predominance. Prostate cancers are at the forefront of these urological cancers. The establishment of a cancer registry would allow better follow up of cancers in our countries.

Introduction: Testicular seminoma is a highly lymphophilic germ cell tumor. It is the most common germ cell tumor in young adults. We are reporting one case of testicular seminoma complicated with an acute generalized peritonitis (AGP), in order to describe the circumstances of diagnosis and discuss about treatment. Observation: It involved a 39-year-old patient, admitted for vague abdominal pains that were evolving since 72 hours with a history of right orchiectomy because of testicular seminoma in 2011. The analysis revealed a peritoneal syndrome, a right inguinal lymphadenopathy of 10 cm diameter and an empty right scrotum. The exploration revealed fistulized necrotic retro-peritoneal lymphadenopathies in the peritoneal cavity and ileal perforation on contact with these lymphadenopathies. Necrosectomy and ileal resections were performed. After the operation, the scanner revealed a conglomeration of retro-peritoneal adenomegalies extending to the right femoral region associated with bilateral pleurisy. The β-HCG and the LDH were 8000 IU/L and 24,500 IU/L, respectively. The seminoma was ranked T3N3M1. The immediate post-operative care was uneventful. The patient was lost from sight for a month and was readmitted in a context of alteration of his general condition. He died before the end of the pre-chemotherapeutic assessment. Conclusion: Scrotal mass is the usual way of revelation of testicular seminoma. In poorly followed-up cases, exceptional complications such as peritonitis may occur and are direct consequences of poor prognosis.

The objective is to study the knowledge that albinos have on skin cancers, and their attitudes in terms of primary prevention and the screening practices for skin cancers in Burkina Faso. Methods: This is a cross-sectional and descriptive KAP study conducted from May 18th to July 7th 2015. It involved albinos aged at least 12 years. Their general knowledge, prevention attitudes and screening practices were considered. Results: All the responding albinos had already heard about skin cancers. Their main source of information was health workers (65.6%). They were showing at least two risk factors (99.2%) but only 68.3% affirmed having already undergone screening for skin cancer. Ignorance of the existence of screening was the main obstacle to it (16/26). The prevention means used was sun avoidance, the use of cream and protection clothing respectively in 84%, 41.5% and 51.2%. The skin lesions found were hyperpigmented macules (77.8%) then actinic keratosis (40.7%) and finally cheilitis (35.8%). We detected 4 cases of skin cancers confirmed by biopsy. Conclusion: Risk factors are frequent. Participation to screening is still insignificant. A lot is still to be done to extend the protection means. A good awareness-raising campaign and the accessibility to protection means remain for all, the best defense in the fight against skin cancers in albinos.

Forest ecosystems help conserve the quality of water resources in aquatic habitats. The conservation of biological diversity in aquatic and terrestrial ecosystems remains a communal concern. Aquatic ecosystems and resources are vulnerable but can be preserved and protected by forests. In sub-Saharan regions of Africa, water from ecosystems such as ponds still play important role in the livelihood of local populations. Water from temporary ponds is used by local populations for multiple needs; however, in this part of the world, the population is increasing, thus increasing human needs and activities and land use in the region. Land-use changes lead to deforestation, land degradation and the decline in freshwater, affecting human health and well-being. Forest degradation leads to the decline in ecosystem goods and services, particularly those related to watersheds. This study conducted in eastern Burkina Faso aimed to assess water quality of temporary ponds in protected forest areas (reserves) and surrounding villages. It was conducted in 61 temporary ponds where physical, chemical and biological variables were measured, such as water surface area, depth, transparency, macrophyte cover, pH, dissolved O2, conductivity, nutrient concentrations and algae biomass. The results showed that at p < 5%, water surface area (p = 0.02), depth (p = 0.00), nutrient content (p = 0.00), and algae biomass (p = 0.04) were significantly higher outside reserves than inside reserves. In contrast, macrophyte cover (mean cover percentages 53 vs. 44.5%) and water transparency (p = 0.02) were higher inside reserves. The variations in conductivity and pH were not significant. All trends showed the influences of human activities on water characteristics and the role forests and land cover had in preventing negative human impacts and disturbance of temporary ponds. Forests and land cover are important to water quality conservation and algae biomass regulation in temporary ponds. Prot

Drinking water sources in many African countries have been progressively degraded over the past decades. This degradation due to human activities leads to the proliferation of algae, especially toxin-producing cyanobacteria. The presence of toxigenic algae in water has adverse consequences on human and animal health. This study aimed to determine the diversity and density of Cyanobacteria and Desmids and to identify toxin-producing cyanobacteria and environmental variables that influenced the structure of these groups of microalgae in the Loumbila reservoir in Burkina Faso located in the western part of Africa. Algal samples were collected and physico-chemical parameters were measured. Plankton species were observed under a light microscope and identified using standard methods. Species density was determined by cell counting using a Fuchs-Rosenthal chamber. Kruskal Wallis and Pearson correlation tests were performed using R software. A canonical analysis was performed using CANOCO software. In total, 205 algal species were inventoried, of which 83 species composed of 37 species of Cyanobacteria and 46 species of Desmids were identified. Microcystis aeruginosa, Staurodesmus convergens and Cosmarium connatum var africanum had the highest presence index respectively (100%, 83.333% and 77.77%). Among cyanobacteria species, toxin-producing species (30 species) and microcystin-producing species (28 species) had the highest number. In terms of species density, Microcystis aeruginosa was the most abundant species. The density of toxin-producing cyanobacteria was positively correlated (p < 0.05) with temperature, pH, dissolved oxygen, transparency, nitrates, and orthophosphates. However, at p < 0.05, desmids community was only correlated with dissolved oxygen, transparency, and conductivity. Furthermore, canonical analysis showed that temperature, dissolved oxygen, transparency, and orthophosphates influenced the density of both
