Aims: Infertility is a major problem in our current societies and the Fertilia medical clinic in Bamako is a center for medical assistance in procreation (MAP) where there is an increasingly growing demand for ultrasound. The objective of our study was to investigate the ultrasound causes likely to prevent the occurrence of pregnancy in a group of infertile and subfertile women. Subjects and Methods: This was a 5-year cross-sectional and prospective study, between January 2017 and January 2022, which involved 250 women wishing to become pregnant (infertile or subfertile), who came for pelvic ultrasound or follicular monitoring and who agreed to participate in our study. The parameters used were ultrasound reports including uterine, ovarian and tubal pathologies. It should be noted that in some cases no ultrasound cause of infertility was found. Data were entered and analyzed in SPSS. Results: 250 women were recruited into our. The average age was 32 years with extremes ranging from 17 to 51 years. 179 patients or 71.6% were between 17 and 35 years old. 139 patients or 55.6% had secondary infertility against 44.4% primary infertility. 202 patients or 80.8% had at least one ultrasound lesion and 48 patients or 19.2% had no significant ultrasound abnormality. The most represented ultrasound lesions were of uterine origin with 72.20%, 23.7% ovarian lesions and 04% tubal lesions. Uterine lesions were dominated by myomas, adenomyosis, endometrial polyps, uterine malformations and synechiae. As for ovarian lesions we noted cysts, polycystic ovary syndrome (PCOS), ovarian endometriosis, non-follicular ovaries and tubal ultrasound lesions showed unilateral or bilateral hydrosalpinx. Conclusion: In our study, ultrasound was an invaluable contribution to the diagnosis of the causes likely to explain subfertility and infertility in our respondents. She highlighted uterine, ovarian and tubal lesions, some of which could be corrected and pregnancies ensued.

Background: The endometrium is the tissue that lines the inside of the uterus. It undergoes multiple changes during the menstrual cycle and prepares to welcome the fertilized egg. Endovaginal ultrasound is a first-line examination in the assessment of female infertility. Objective: We aimed to determine the impact of endometrial status by endovaginal ultrasound on the outcome of embryo transfers. Subjects and Methods: This was a prospective cross-sectional study of 150 women collected between January and October 2020 at the “Le Diafounou” medically assisted procreation laboratory. Were included in the study, women presenting for desire of pregnancy and having continued the treatment until the transfer of fresh or frozen embryos. An uterine score was used. This score took into account the thickness of endometrium, it is coffee bean aspect, the presence of the notch, the echogenicity of the endometrium, the pulsatility index, the presence of the flow at the end of diastole and sub-endometrial flow. Ultrasounds were performed using a General Electric logic 500, logic 9 and Voluson E8 device. The data was entered into Excel and then analyzed using SPSS version 21. Results: 150 women were selected for the study. 83 women or 55.3% were between 17 and 35 years old and 44.7% were over 35 years old with an upper limit of 50 years old. The number of women who became pregnant was 69% or 46%. The average thickness of the endometrium was 11.40 mm with extremes of 4.65 mm and 18.6 mm. There was a correlation between the thickness of the endometrium and obtaining a pregnancy (p i.e. 88.7%. The pulsatility index was relatively low for those who started a pregnancy, i.e. 90%. The high pulsatility index is one of the reasons for the failure of embryo implantation. The correlation was significant (p = 0.009). 141 women had no notch in the uterine arteries, i.e. 94%. 94 women or 62.7% had a triple line endometrium or typical coffee bean appearance. End-diastolic flow was observed in 12

Varicocele and Spermogram Abnormality: About 264 Cases at the Fertilia Medical Clinic in Bamako

引用

Open Journal of Medical Imaging 2023年第3期13卷 84-91页

Aims: To determine the impact of varicocele on the result of the spermogram in a group of hypo-fertile or infertile men. Patients and Method: This was a cross-sectional, descriptive study concerning 264 men collected between February 2020 and March 2022 at the Fertilia medical clinic in Bamako. The study population consisted of consenting male subjects presenting for infertility. All of our patients had already done a spermogram, they then benefited from a scrotal Doppler ultrasound. The scrotal echo-doppler was completed by an abdominal and pelvic echography in search of a possible etiology, in particular a renal cancer, a thrombosis of the renal or spermatic vein, a retroperitoneal mass or a nutcraker syndrome. Testicular volume was measured on ultrasound according to Lambert’s formula (length × width × height × 0.71). A volume = 16 ml was considered normal. Results: 264 patients were recruited in ours. The average age was 33 years with extremes ranging from 25 to 65 years. 149 patients or 56.44% were between 30 and 45 years old. 213 patients or 80.68% had primary infertility. All the patients, i.e. 100%, had a sperm anomaly and dilation of the pampiniform plexus veins. The most common sperm abnormalities were oligoasthenoteratozoospermia, which concerned 214 patients, or 81%, followed by azoospermia (40 patients, or 15%) and oligospermia (10 patients, or 4%). 213 patients or 80.68% had a Hirshen grade II varicocele, 45 patients or 17% had grade I and 06 patients or 2.27% had grade III. Among the 6 patients, 04 had left testicular atrophy and 2 bilateral atrophy. The venous reflux was more accentuated on the left than on the right. Conclusion: Varicocele is significantly found in men with infertility. Sperm alterations concern both the concentration of spermatozoa, their mobility and their vitality. Even if the mechanism of alteration of the sperm parameters is not well elucidated, our study made it possible to make the link between the dilation of the veins of th

The aim of this study was to report a case of multi-visceral sarcoidosis at the Mother-Child Hospital Center (CHME) “Le Luxembourg” in Bamako, Mali. Observation: This is a patient aged 62 at the time of consultation, a housewife, residing in the Banconi district, who was referred to us for thoracic-abdominopelvic imaging for chronic liver disease. After several diagnostic errors, the thoracic-abdominopelvic CT scan and liver MRI performed in our center showed, at the thoracoabdominal level, bilateral diffuse pulmonary micronodules and bilateral mediastinal-hilar lymphadenopathy;on the abdominal level, a dysmorphic liver with plaques of steatosis and a granular appearance of the liver parenchyma without periportal fibrosis. These imaging data combined with those from the liver nodule biopsy and biology confirmed the diagnosis of sarcoidosis type II. Treatment with corticosteroids gave satisfactory results and the patient recovered after 18 months. Clinical and CT monitoring 2 years from the start of the disease and 2 months from the end of treatment showed complete resolution of the lesions. Conclusion: The multi-visceral location of sarcoidosis is an entity whose diagnosis remains difficult;diagnostic and interventional imaging has an important place in its management.

Ross’ epidemic model describing the transmission of malaria uses two classes of infection, one for humans and one for mosquitoes. This paper presents a stochastic extension of a deterministic vector-borne epidemic model based only on the class of human infectious. The consistency of the model is established by proving that the stochastic delay differential equation describing the model has a unique positive global solution. The extinction of the disease is studied through the analysis of the stability of the disease-free equilibrium state and the persistence of the model. Finally, we introduce some numerical simulations to illustrate the obtained results.

In this paper, we treat the spread of COVID-19 using a delayed stochastic SVIRS (Susceptible, Infected, Recovered, Susceptible) epidemic model with a general incidence rate and differential susceptibility. We start with a deterministic model, then add random perturbations on the contact rate using white noise to obtain a stochastic model. We first show that the delayed stochastic differential equation that describes the model has a unique global positive solution for any positive initial value. Under the condition R0 ≤ 1, we prove the almost sure asymptotic stability of the disease-free equilibrium of the model.

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.
