Objective: The purpose of this study was to analyze the opinions of gynecologists, midwives, and interns/Specialist students practicing in Senegal about the use of IUD, and to assess factors that stand as obstacles to IUD prescribing. Patients and methods: An online questionnaire was developed to assess providers’ IUD practices and attitudes. The questionnaire was based on the one used in a Swiss study on the same topic. The platform used was Google forms. The questionnaire was shared in associative platforms involving gynecologists, midwives and interns/Specialist students. Results and comments: We received 292 feedbacks. Gynecologists represented 13.7% of the sample, interns and specialist students 11.3% and midwives 76%. Parity is a determining factor in IUD selection. The care-providers were concerned about the followings, which might have prevented the use of IUD, even though it was indicated: infections (75.7%), pelvic pain (61.3%), expulsion (48.3%), increased risk of perforation (46.9%), women’s appreciation (45.2%), ectopic pregnancy (33.9%) and sexual behavior (28.4%). Conclusion: Our study reveals that providers’ apprehensions and concerns severely limit the availability of IUDs. These concerns are often unf

The principle of PCNL is the extraction through a nephrostomy channel of kidney stones which are defined as the presence of crystalline concretions in the kidneys. Objectives: The objective of this work was to study the epidemiological, clinical and paraclinical aspects of patients with renal lithiasis treated by PCNL and on the other hand the different technical aspects of PCNL. Materials and Methods: This was a retrospective descriptive study, conducted in the urology department of HOGIP, covering the period from January 2015 to January 2019. We studied the demographic and clinical aspects of patients presenting renal lithiasis;we also studied the technical aspects and treatment outcomes. Statistical significance was set for α = 0.05. Results: Our series covered 82 PCNLs performed during the study period. The average age was 45.95 years, the age group [40 - 49 years] was more affected. Our study involved 44 men and 38 women, a sex ratio of 1.15. At the clinic, atypical lumbar pain was more frequent in 45.83% of cases. On URO-CT, the calculations were located more at the pyelic level (31.2%) and lower caliceal (27.2%). The size of stones measured between 15 and 20 mm in 30.52%. The stone density was between 500 and 1000 HU in 47.54% of cases. Intraoperatively, the patients were placed in lateral decubitus in 41.46% of cases. Only one access to the kidney was necessary in 87.8% of cases. The lithoclast was used in 65.85% of cases. The overall success rate (stone free) in our series was 96%. The majority of cases, 41.44%, drainage were done by natural means (totally tubeless). The average duration was 92 minutes. The complications encountered in our experience concerned 10 cases, a rate of 12.19%. Conclusion: Urinary lithiasis is more and more frequent in our regions. The development of Endo-urology offers several therapeutic options. Thus, PCNL occupies an important place in the management of kidney stones.

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.

Upper urinary tract lithiasis is a condition characterized by the presence of stones which is a stony concretion of crystallized substances in the kidney and/or ureter. Objective: The objective of this work is to study the epidemiological, clinical and therapeutic aspects of upper urinary tract stones on the one hand, then to compare the different types of surgical treatments and their results. Materials and Methods: This is a retrospective and descriptive study focusing on the surgical management of upper urinary tract stones, between January 2017 and December 2020, at the Urology department of the Hopital General Idrissa Pouye. Results: During the study period, 7.59% of surgical interventions performed were related to the treatment of upper urinary tract stones. Average age was 45.20 ± 16.4 years, the age group [41 - 60] years was more affected with 42.68%. A history of urolithiasis was present in 25.52% of cases. Lower back pain was present in 97.48% of cases. On URO-CT scan, the stone was located more at the level of the ureter (49.57%). The size between 10 to 15 mm was more frequent (30.96%) and the density greater than 1000 HU was more frequent (33.47%). The most used therapeutic procedure was ureteroscopy (52.08%), followed by PCNL (40.83%) and open surgery (7.08%). The success rate (stone free) was 93.68% for the URS, 89.36% for the PCNL. The length of hospital stay for open surgery was 6.76 ± 4.25, for PCNL 2.62 ± 2 days and for URS 1.75 ± 1.62 days. Postoperative complications were present in 23.52% for open surgery, 11.22% for PCNL and 8% for URS. Conclusion: Urolithiasis is constantly growing in our regions. Effective endourological treatment is increasingly replacing open surgery. However, global access to these new techniques in our regions is slow to be effective.

In our center where a lot of water is used for watering and cleaning the classrooms, the management of wastewater as a resource can be a real opportunity. The main objective of this research is to size and determine the effectiveness of natural treatments of the wastewater treatment system composed of a septic tank and a treatment plant which would be installed in site Ngoundiane of Alioune DiOP University, in Bambey, Senegal. Overall, we noted that the sized septic tank dimensioned in our study allows the efficient settling of wastewater which depends on the flow point ratio and useful settling surface area that must be lower than the upward speed that corresponds to 0.8 m/h. The sizing of the septic tank led us to obtain a useful capacity of 88 m3 and a horizontal surface of 44 m2 with a height of 2 m. The ratio between the flow of the wastewater received and the upward speed is 0.17 m/h and is significantly lower than the recommended speed. In addition, the station will be able to eliminate 80.418% of the Biochemical Oxygen Demand (BOD), 75.522% of the Chemical Oxygen Demand (COD), 92.385% of Suspended Solid (SS) and 43.427% of Nitrogen compounds.

There are several sources of energy recovery in the ambient environment. The radiofrequency energy harvesting system is used to harvest the electromagnetic energy in the air by processing energy sources to charge low-power electronic devices. Rectenna termed as a rectifying antenna is a device that is used to convert electromagnetic waves in the air into direct electric current. In this work, we have designed firstly the patch antenna with a small size printed on the FR4 substrate (40 mm × 47.5 mm × 1.6 mm) and then the rectifier circuit. This rectenna is capable of working at a frequency range of 2.45 GHz. The antenna was designed using High Frequency Structure Simulator (HFSS) 13.0 software with the result of working frequency of 2.453 GHz, S11 (Return Loss) -52 dB, Voltage Standing Wave Ratio (VSWR) 1.036, gain 3.48 dB and bandwidth 150 MHz. The efficiency of rectifier design on Advanced Design System (ADS) 2011 software is 54% at the input power of 0 dBm at 2.45 GHz. The resulting system is capable of producing electrical energy to power low-power electronic equipment at a DC voltage of 732 mV.
