作者： Karam Harou Aboubacar Sidiki sidibe Hicham Abdelkhalki Abderaouf Soummani Department of Obstetrics and Gynecology Caddi Ayyad University Medical Hospital Med VI Marrakech Morocco

Velamentous insertion of the umbilical cord corresponds to the insertion of the cord directly on amniotic membranes. It is a rare situation whose frequency varies from 0.5% to 1.69% of single pregnancies. It must be diagnosed during the morphological ultrasound of the 2nd trimester, actively looking for the association with a vasa previa, due to the risk of fetal haemorrhagic threat. We report an antenatal diagnosis of velamentous cord insertion and its management with literature review.

作者： Bourama Coulibaly Drissa Traore Bakary Dit Dembo Sylla Marie Bernard sidibe Electrical Engineering Department Normal School of Technical and Vocational Education (ENETP) Bamako Mali National Engineering School Abderhamane Baba Tour (ENI-ABT) Bamako Mali

This study aims to identify the causes of sensor jams and its impact on the operation of vending machines. The vending machine is a machine that automatically dispenses products such as drinks, tickets, sandwiches and biscuits, by inserting change or credit card into the machine. This technological feat is due to the advent of sensors. A sensor is a part of the measurement chain, it receives the quantity to be measured and provides information directly linked to this quantity. However, these vending robots are faced with malfunctions linked to sensor jams. The identification of the jam phenomenon was possible thanks to the inspection and monitoring of the various sensors installed on the vending robot. And Cadence software was used to model, control and locate the jammed sensor(s). The various tests were carried out by setting the robot in motion to better understand the causes of the phenomenon. The jam is therefore the phenomenon which triggers the sensors permanently, which causes the automatic vending robot to stop functioning. And this jam was due to the presence of water droplets on the sensor or dirt. This presence of water droplets on the sensor is linked to an increase in temperature. Controlling the temperature and locating the jammed sensor has made it possible to considerably reduce jamming and its harmful effects on the vending machine robot.

Introduction: The authors wanted to study the prevalence of ocular trauma in the ophthalmology unit of the CSREF of Kati. Patients and method: This is a retrospective study, covering the period from January to December 2015, carried out in the ophthalmology unit of the CSREF in Kati. Results: The sample consisted of 568 patients, or 6.82% of ophthalmological consultations. Children aged 0 to 14 years accounted for 154 (27.11%) of the trauma cases. Bruises constitute the main circumstance (58.1%) of eye trauma, followed by domestic accidents (15.6%). Closed globe ocular trauma was the main type of trauma (61.6%), followed by ocular adnexal trauma (30.1%) and open globe trauma (8.3%) in which the penetrating wound was the lesion, the least common (2.6%) but the most serious. Medical treatment was the most used therapeutic modality in 82.4% of cases, followed by surgery with 17.6% of cases. The evolution of the lesions after treatment was favorable in 85.6% of cases and unfavorable in 14.4% of cases. Complications were observed in 5.8% of cases and sequelae in 8.6% of cases. Conclusion: Ocular trauma constitutes an important reason for ophthalmological consultation at the CSREF of Kati. The severity of some of these lesions requires frequent recourse to surgery. The complexity of the treatment should encourage us to favor preventive measures.

Introduction: Biometrics therefore corresponds to the measurement of the morphological elements of humans. One of the most common ultrasound requests by clinicians is the assessment of liver size. The aim of our study was to study liver biometry using ultrasound in healthy adult subjects. Material and Methods: This was a prospective, descriptive and analytical study, carried out at CHU Point-G over a period of 7 months. A liver ultrasound was performed on 100 individuals without lesions, by a doctor in his final year of specialization in radiology and medical imaging. For each subject, we determined the height and anteroposterior diameter of the right liver and the left liver. Results: The mean age was 39.05 ± 16.86 years. The body mass index (BMI) 18.5 - 24.9 group was the most represented with 58%. The mean height of the right liver was 138.40 ± 14.85 mm. It was 136.81 ± 14.70 mm in men and 139.92 ± 14.99 mm in women (P = 0.306). That of the left liver was 95.55 ± 14.34 mm, in men, it was 91.79 ± 13.51 mm and 99.16 ± 14.31 mm in women (P = 0.019). We found a significant correlation between right liver height and BMI (P = 0.013). Conclusion: The mean values of liver biometry were established in our series. There was a significant correlation between right liver height and BMI. Liver ultrasound remains a reliable technique for liver biometry.

Inguinal hernia in children is a congenital pathology in children linked to the persistence of the peritoneo-vaginal canal in children and the NüCK canal in girls;persisting into adulthood. This work aimed to study inguinal hernia in children in the general surgery department of the Reference Health Center of Commune I of the Bamako District;to determine the frequency of inguinal hernia;describe the epidemiological, clinical and therapeutic aspects of inguinal hernias and in order to evaluate the cost of treatment. This was a prospective study from April 2017 to March 2018 during which 60 children with an inguinal hernia were collected. Inguinal hernias in children represented 9.23% of patients operated on in the department. The average age was 59.23 months with extremes of one month and 180 months and a standard deviation of 49.23 years. The male sex was dominant with a sex ratio equal to 9:1. The notion of prematurity was found in 11.7% and was associated with a testicle not in place in 1.7% of cases. 41.7% of our patients were referred by a doctor and 66.7% of patients presented with painless, intermittent inguino-scrotal swelling (83.3% of cases). The hernia was discovered before one week of life in 50% of cases. Inguinal swelling was absent in 11.7% but observed intraoperatively. The inguinal hernia was unilateral in 91.7% of cases and 70% of hernias were discovered by the parents during pushing efforts. The inguinal hernia was located on the right in 61.7% of cases. The hernia swelling was soft, painless, impulsive and reducible in 78.3% of cases. The swelling was inguino-scrotal in 58.3% of cases. The hernia was simple in 95% of patients and hernial strangulation was observed in 3 cases or 5% of cases. 98.3% of patients were ASA I.
