Introduction: The portal vein (PVD) diameter is one of the predictive variables of portal hypertension. This diameter can differ according to the population. The objective of this study was to determine the PVD in a healthy adult population in Parakou using ultrasonography. Methods: A cross-sectional descriptive study was conducted in the medical imaging department of the Borgou and Alibori University-affiliated Hospitals in Parakou from July 1st to October 1st, 2019. The study population consisted of 201 healthy adults. The ultrasound diameter of the portal vein was measured at the level of the hepatic hilum on a cross-sectional epigastric view and on an oblique intercostal view. An association was sought between the PVD and sociodemographic and anthropometric factors. Results: The mean age was 28.97 ± 10.56 years and the sex ratio (M/F) was 0.79. The mean PVD in regular breathing (FB) was 9.83 ± 0.95 mm with a 95% confidence interval of [9.70;9.97], a 95th percentile of 11.49 mm with extremes of 7.50 mm and 12.23 mm. PVD was correlated with age, sex, weight, height and abdominal girth. After multiple linear regressions (r = 0.19), there was correlation between the PVD in normal breathing with age (p = 0.0090), weight (p = 0.0026), body mass index (p = 0.0171) and body surface (p = 0.004). Conclusion: A PVD greater in normal adults is less than 12 mm and seems to be correlated to the subject age, weight, body mass index and body surface. A more than 13 mm PVD should lead to the suspicion of portal vein hypertension in adults in our populations.

Goal: The goal of this study is to define the epidemiological profile and identify the different brain lesions diagnosed in ultrasonography in preterm infants in Benin environment. Patients and methods: It is a prospective cross-sectional study of analytical aiming. It took place over a period of 6 months, from May 1st to October 31st, 2012 at the National Hospital University Centre Koutoukou Hubert Maga in neonatal units and medical scanning unit. It covered 105 premature newborn, classified into the very prematurity and the moderate prematurity. Results: The very premature represented 35.2% and the moderate premature 64.8%, with an average of 33.5% and 1.9 of standard deviation. The average age when implementing ultrasonographic transfontanellar was 7.2 ± 4.6 days old. The lowest birth weight was observed in very premature with p = 0.0025. The nasopharyngeal septum pellucidum was the most found lesions in 46 preterm infants (43.8%) with no statistically significantly difference in two groups, followed by the ventricular haemorrhage found in 21 preterm infants accounting for 20%, and the grade 1 or sub-ependymal haemorrhage prevailed in 14 premature accounting for 66.7%, afterward periventricular leukomalacia in 4 premature infants and hydrocephalus in 2 premature. Conclusion: The nasopharyngeal septum pellucidum and the sub-ependymal ventricular haemorrhage were the predominant anomalies in premature infants followed by leukomalacia.

Sansuamou kofi-mensa savi de tove Olivier Biaou Vicentia Boco National Teaching University Hospital Hubert Koutoukou Maga (CNHU-HKM) Medical Scanning Unit/University of Abomey-Calavi Cotonou Benin Radiology department Teaching University Hospital-Mother and Child Hospital Cotonou Benin (CHU-MEL) Radiology and Medical Imaging department Departemental Teaching University Hospital Borgou Parakou Benin

Objective: The aim of this piece of work is to study the contribution of pelvic ultrasound while exploring pelvic pathologies at Hubert Koutoukou Maga Teaching University Hospital “CNHU-HKM” and at the Teaching University Hospital of Mother and Child “CHU-MEL” of Cotonou. Patients and Methods: A descriptive, cross-sectional and analytical study with prospective collec-tion was carried out at the University Clinic of Gynecology and Obstetrics “CUGO” at the CNHU-HKM and in the gynecology department of the CHU-MEL, over a period of 4 months (May to August 2018). We included in this study women over 12 years old who performed a pelvic ultrasound and were followed in the aforementioned health centers. Results: The population of the study consisted of 181 patients. The pelvic ultrasound request frequency was 18.84% compared to all ultrasound examinations. The age group of 25 - 29 years old was the most represented (22.10%). Pelvic pain was the first mo-tive for pelvic ultrasound request (39.8%). The abnormalities found by ultra-sound were uterine and ovarian respectively in 55.4% and 38% of cases. Uter-ine pathology was dominated by uterine myoma (44%). Ovarian cyst (13%) and ovarian dystrophy (14%) were the main ovarian pathologies. There was a statistically significant relationship between certain reasons for consultation, mainly metrorrhagia, dysmenorrhoea, amenorrhoea, leucorrhoea (p Conclusion: The ultrasound remains the first choice examination and is of a great value in exploring pelvic pathologies. In most cases, it helps to find the responsible lesion and to make the appropriate ther-apeutic decisions.

Introduction: Tendinopathy of the thoracic limb (TMT) is frequent, and is responsible for an important socio-professional handicap. Medical imaging, in particular, ultrasound has a major role in contributing to the diagnosis. As the use of ultrasound is recent in osteoarticular pathology, especially in Africa, we proposed to determine the contribution of imaging in the diagnosis of tendinopathy of the thoracic limbs in a country with limited resources. Patients and Method: A descriptive and analytical cross-sectional study of patients with tendinopathy of the thoracic limb who consulted the rheumatology department of the CNHU-HKM of Cotonou from August 6, 2019 to October 6, 2019. We evaluated the concordance of thoracic limb tendinopathy between imaging (radiography and ultrasound) and the clinic on the one hand and then between radiography and ultrasound on the other hand. The analysis of the collected data was carried out with the Epi-info software version 7.***.1.0. Then the concordance was evaluated by the kappa coefficient. Results: Fifty- two (52) patients with 104 joints were evaluated. The average age was 54.92 ± 3.40 years. Clinically, rotator cuff tendinopathy was the most frequent abarticular pathology (45.19%). The clinical-ultrasound agreement was strong (k = 0.7527) for the shoulders, very strong (k = 0.9360) for the elbows and moderate for the wrists (k = 0.6695). The clinical-radiographic agreement was weak (k = 0.2316) at the shoulder level and very weak (k = 0.2087) at the elbow level. The radio-ultrasound agreement was very low in the shoulders (k = 0.1522), elbows (k = 0.1859) and wrists (k = 0.0001). Conclusion: The contribution of imaging in the diagnosis of TMT remains certain even in a country with limited resources like ours. Ultrasound is a reliable examination for the diagnosis of non-traumatic tendinopathy of the thoracic limb with a good clinical-ultra- sound concordance a

Background: Gastric volvulus is a rare surgical emergency that causes an upper digestive obstruction due to a rotation of the stomach greater than 180°. Observation: We report the case of a 2-year-old patient referred from a health care facility for incoercible vomiting. On admission, the clinical examination revealed that the condition started about 1 month back with poor general and nutritional condition. Pyloric stenosis was suspected but this hypothesis was rejected based on abdominal ultrasound. Further investigations were done with an abdominal X-ray and an upper gastrointestinal barium study which led to the conclusion of an organo-axial gastric volvulus. The patient died in the course of treatment. Conclusion: Gastric volvulus is an often-misunderstood condition. Upper gastrointestinal barium study remains the gold standard of diagnosis. Its management is surgical.

Introduction: Irritable bowel syndrome (IBS) is a known public health burden in western countries while only a few studies have been published on this disease in Africa. The objective of this study was to determine the prevalence of IBS in the general adult population of Cotonou (Benin), its associated risk factors and its impact on patients’ daily life. Method: This was a descriptive and analytical cross-sectional study conducted over one month. Data was collected via a questionnaire. IBS was defined by the Rome IV criteria. Results: A total of 768 participants were included, with a male predominance (sex ratio 1.8). The mean age of the participants was 30.6 years, with extremes of 15 to 76 years. The prevalence of IBS in our study was 4.2%. IBS-D was the most common subtype (34.4%). IBS symptoms were influenced by diet (46.9%), stress (31.3%) and lack of sleep (15.6%). In the univariate analysis, the risk factors associated with IBS were: dendi and Otamari ethnicity (p = 0.015), low level of education (p = 0.047), family history of IBS (p = 0.026), smoking (p Conclusion: despite IBS frequency, patients with IBS rarely seek medical attention. The public should therefore be informed about this condition to reduce its impact on their daily life.
