Studies carried out in the delta and the lower valley have demonstrated, through ethnobotanical surveys, the importance of the species Nymphaea lotus L. and Nymphaea micrantha Guill. et Perr in the diet. The seeds are used in food and pharmacopoeia with a good appreciation by the indigenous population, especially in the diet of diabetics. However, studies on their biochemical aspects are still very rare in the literature. It is for this reason that this study was conducted to gather useful scientific information to allow a better appreciation of the pharmacological potentialities of these seeds. To do so, seeds were collected in ponds, tributaries of the Senegal River, dried in the shade, and divided into three different batches: a batch of red seeds of N. lotus, a batch of black seeds of N. lotus, and a batch of seeds of N. micrantha. Chemical screening, tannin, flavonoid, and polyphenol assays as well as antioxidant power of the seeds were carried out according to official standard methods. The results obtained in the qualitative analysis showed the presence of a high quantity of tannins, total phenols, flavonoids, and alkaloids, as well as a lower quantity of cardiac glycosides and the absence of anthracene compounds and saponosides in the seeds. The assay showed that Tannins are the highest (38.118 ± 0.021 to 118.132 ± 0.034 mg EAT/g DM) followed by flavonoids (24.057 ± 0.113 to 31.970 ± 0.087 mg EC/g DM) and polyphenols which are the lowest (0.544 ± 0.054 to 1.955 ± 0.120 mg EAG/g DM). In addition, these seeds have a high antioxidant power with high inhibition percentages, ranging from 83.92% ± 1.40% to 87.67% ± 0.16%. The promotion of their consumption could thus have a positive impact on the health of the populations of the Senegal River valley.

Objectives: The aim of our study was to investigate the relation of some sociodemographic factors and delays presentation in breast cancer. Patients and method: This was an observational study in Breast Unit of Aristide Le Dantec Teaching Hospital in Dakar. Were included in the study all patients followed for breast cancer from January 2008 to December 2014. The following variables were selected and stratified: age, place of living, educational attainment, menopausal status, socioeconomic status and family history of breast cancer. For each variable, an association with the stage and presentation delay was assessed. Results: Two hundred and fifty nine (259) patients met the inclusion criteria. No correlation was found between the studied socio-demographic factors and delay. Negative history of family breast cancer was associated with presentation delay. The only factor associated with locally advanced breast cancer after adjusting confounding factors was low level of income. Conclusion: A significant percentage of women with breast cancer in Senegal are experiencing presentation delay. Coordinated efforts with public health department are needed to educate the focused groups and mitigate the barriers.

作者： Amadou Sow modou gueye Djibril Boiro Idrissa Demba Ba Abou Ba Aliou Thiongane Papa Moctar Faye Amadou Lamine fall Ousmane Ndiaye Chair of Pediatrics Cheikh Anta Diop University of Dakar Fann Senegal

Introduction: The COVID 19 pandemic has prompted the world to implement drastic prevention methods based on limiting population movements that have an impact on public health policies such as vaccination. The objective of this work was to evaluate the impact of these prevention measures on routine vaccination in hospitals since the advent of the pandemic in Senegal. Methodology: This is a retrospective cross-sectional study carried out in August 2020 in the vaccination unit of the Abass NDAO hospital centre. We compared data from the vaccination unit during the period from March to August of the last three years (2018, 2019 and 2020). The parameter studied was the number of vaccine doses administered for the different periods according to the expanded programme of immunization. Results: For the vaccines administered in the sixth week in April, the number of doses was 36 in 2018, 29 in 2019 and 15 in 2020, i.e. a 50% drop compared to March. In July the number of doses administered was 40 in 2018, 35 in 2019 and 15 in 2020, a reduction of 42% compared to 2019. Conclusion: Measures to fight this pandemic should not make us forget routine vaccination, especially in our resource-constrained countries. It is essential to continue vaccination for children and to identify children who have missed vaccine doses for catch-up.

Open Journal of Obstetrics and Gynecology 2016年第1期6卷 50-55页

作者： Mamour gueye Mame Diarra Ndiaye-gueye Serigne modou Kane-gueye Fatou Niass Dia Aissatou Thiam Sr. Elisabeth Diouf Jean Charles Moreau Gynecologic and Obstetric Clinic Aristide Le Dantec Teaching Hospital Cheikh Anta Diop University Dakar Senegal

Objectives: This study aimed to assess efficacy of intramuscular methotrexate 8-day protocol in the treatment of low-risk gestational trophoblastic neoplasia and also identify prognostic factors associated with treatment failure, necessitating second line chemotherapy. Methods: This study was performed at Gynaecologic and Obstetric Clinic of Dakar Teaching Hospital, the reference Centre of Gestational Trophoblastic Disease in Senegal. At the beginning of 2011, patients were followed according to FIGO’s recommendations. From 2011 to 2014, we diagnosed 88 low-risk gestational trophoblastic neoplasia (GTN) patients (WHO score < 7). Low-risk patients started their treatment with methotrexate (MTX) based on the 8-day protocol consisting of 1 mg/kg MTX in combination with 0.1 mg/kg folinic acid (FA) every other day. Resistance to treatment was the main outcome. We studied the association of different prognostic factors included in the World Health Organisation (WHO) scoring system and resistance to the initial single agent chemotherapy. Results: Eighty-eight patients were diagnosed for GTN during the study period. Average age was 31 years. The antecedent pregnancy was molar in 98.1% of cases. Seventy-four patients underwent remission after single agent-chemotherapy. Resistance rate to single-agent chemotherapy was 15.9% (14 patients). Nine of them achieved remission after second line chemotherapy. WHO score was significantly associated with the risk of resistance to single-agent chemotherapy. Other variables included in the WHO as age, antecedent pregnancy, pre-treatment hCG, tumour size and FIGO stage were not significantly associated with resistance. We report five fatal cases. Conclusion: The 8-day protocol consisting of 1 mg/kg MTX in combination with 0.1 mg/kg folinic acid (FA) every other day is effective for women with LRGTN. The only significant prognostic factor for failure is pretreatment WHO score. We highly recommend the use of this protocol particularly in de

Onion is an important vegetable in Senegal horticulture, where it occupies the first place. However in the greatest areas production like the Gandiolais, in the North of Senegal, Pink root disease caused by a soil born fungus Pyrenochaeta terrestris (Hansen) Gorentz, Walker and Larson affects its productivity especially in nursery. On soil sterilized and inoculated by the fungus, we tested 5 natural fungicides and 2 synthetic fungicides, to measure their effectiveness on the Pink root disease on onion, in nursery. The device used is a split plot with 4 repetitions and 8 treatments. The measured variables are the emergence rates, the survival rates and the infestation rates. Our experimentations have shown that, for the emergence rates, there is no significant difference between thiophanate-methyl (Pelt 44), Carbendazim (Bavistine), Azadirachta indica A. Juss and Carica papaya L. It is the same between C. papaya and Moringa oleifera Lam, between M. oleifera and Cassia alata L. It is also the same between C. alata and Crotolaria retusa L. Regarding the survival rates, there is no significant difference between thiophanate-methyl, Azadirachta indica, Carbendazim, C. papaya and M. oleifera. The same is true between M. oleifera and Cassia alata, and between C. alata and C. retusa. Concerning the infestation rates, apart from the control check, all other treatments show no difference.

Introduction: Low birth weight (LBW) is defined as a birth weight 2500 g at birth, regardless of the term of pregnancy. The objective of this study is to evaluate their stature and weight growth from 0 to 9 months of corrected age (CA) in Senegal. Methodology: This is a prospective, descriptive, and analytical cohort follow-up up to 9 months of CA including all live newborns of LBW hospitalized and followed up from 01 August 2019 to 31 May 2020. World Health Organization growth charts were used to assess stature and weight growth. Results: During the study 136 LBW newborns were included. The mean gestational age was 32 weeks of amenorrhea. At discharge, 46 children (33.82%) were exclusively breastfed. At birth, the mean weight was 1487 g (3rd-10th percentile) and the mean height was 41.52 cm (10th-25th percentile). At 9 months of CA, the mean weight was 8119 g (median) and the mean height was 74 cm (median). The children had achieved satisfactory growth in weight (84%) and height (89%). At 9 months of CA, 27% of the children were behind in one of the four areas of psychomotor development. Conclusion: At the end of 9 months of CA, stature and weighted growth was normal.

Introduction: Patients with chronic diseases, especially kidney diseases, frequently use the health care system and free dialysis policies are being implemented in many countries in Africa. This study aimed to evaluate access to care for patients with chronic kidney disease (CKD) in northern region of Saint-Louis. Methodology: In a cross-sectional survey, we included non-dialyzed CKD patients aged ≥20 years who attended outpatient nephrology clinic at University Hospital of Saint-Louis between January 1st and January 31st 2018. Access to care was measured using a questionnaire that integrated dimensions such as availability, geographic and financial accessibility, convenience, acceptability, effectiveness of care and quality of information. Socio-demographic and clinical data were also collected and analyzed with Epi Info 7. Results: Among 97 surveyed patients, 90 were included (response rate of 92.8%). Patients’ mean age was 35.2 years (20 - 89 years) and 55% were male. Only 30% of patients had health coverage either by the government, or private insurance or community health insurance. Access to care was rated as globally low by 73% of participants. However, we noticed some variations according to dimensions of access. Geographical accessibility and convenience of delivered care were good for the majority of patients, while financial access and acceptability of care were considered as very limited. Bivariate analysis showed that acceptability and effectiveness of care were linked to CKD stage while the quality of patients’ information was correlated with their educational level. Furthermore, health coverage was also associated with financial accessibility of care but not with its availability. Conclusion: This study showed that access to care is poor for majority of patients with CKD in Saint-Louis. Identification of the main barriers will help define appropriate strategies to achieve universal access to quality renal care.

引用

Surgical Science 2023年第8期14卷 550-556页

作者： Omar Sow Aissé Thioubou Reymond Saidy Aboubacar Traoré modou D. Ndiaye Mouhamadou L. gueye Ibrahima Ka Madieng Dieng Department of Surgery Peace Hospital Assane Seck University Ziguinchor Senegal Department of General Surgery Cheikh Anta Diop University Dakar Senegal

Laparoscopic colectomy is a standardized technique for the curative treatment of colon cancer, based on the principles of carcinological surgery. It is rarely performed in our region but common practice in developed countries. We conducted a retrospective study of the first 4 cases of laparoscopic colectomy for cancer. The patients were 3 men and 1 woman, with a mean age of 54.2 years. Of the 4 cancers, 3 were localized to the sigmoid and one to the cecum. The main symptom was rectal bleeding. Total colonoscopy with biopsy was performed in 3 patients and the histological type was a lieberkühnian, infiltrative, moderately differentiated adenocarcinoma. Thoraco-abdomino-pelvic computed tomography (TAP CT) was performed in all the cases. Three patients were presented to the multidisciplinary team (MDT) prior to surgery. The operations were one right hemicolectomy and three left hemicolectomies. The mean operative time was 182.25 min [152 - 210]. Average blood loss was estimated at 200 cc. The average hospital stay was 4.71 days. Cancer staging was classified as stage I in 1 case (p T1N0M0) and stage III in 3 cases (pT3N1Mx, pT3N2Mx). Resection margins were healthy. The number of lymph nodes removed was 12, 14, 17 and 13 respectively. Conclusion: This is a safe and reproducible technique, but requires a much higher cost than laparotomy.

引用

Open Journal of Obstetrics and Gynecology 2017年第13期7卷 1292-1299页

作者： Mamour gueye Moussa Diallo Mame Diarra Ndiaye gueye Omar Gasama Abdoul Aziz Diouf Mouhamadou Mansour Niang Mohamed Diadhiou Astou Coly Niassy Serigne modou Kane gueye Marie Edouard Faye Dieme Magatte Mbaye Philippe Marc Moreira Alassane Diouf Jean Charles Moreau Gynecologic and Obstetric Clinic Aristide Le Dantec Teaching Hospital Cheikh Anta Diop University Dakar Senegal

Objective: To assess a training approach in Emergency Obstetric and Neonatal Care (EmONC) to strengthen skills of healthcare providers and reduce maternal mortality. Materials and methods: The approach was based on the skills training using the so-called “humanist” method and “life saving skills”. Simulated practice took place in the classroom through thirteen clinical stations summarizing the clinical skills on EmONC. The evaluation was done in all phases and the results were recorded in a database to document the progress of each learner. Results: We trained 432 providers in 10 months. The increase in technical achievements of each participant was documented through a database. The combination of training based on the model “learning by doing” has ensured learning and mastering all EmONC skills particularly postpartum haemorrhage management and reduced missed learning opportunities. Conclusion: The impact of training on postpartum haemorrhage management and maternal mortality is a major challenge in terms of prospects.
