Introduction: A thyroid nodule is a localized hypertrophy within the thyroid parenchyma. The aim of our study was to study the benefit of ultrasound in the Ti-rads classification of thyroid nodules. Methodology: This was a prospective study with a descriptive aim, with prospective collection, which took place over a period of 17 months at the “Marie Curie” medical clinic. The ultrasound machine used was a Voluson E8 from 2011 and the examinations were carried out by two radiologists and two experienced sonographers. The parameters studied were sociodemographic data;clinical data and ultrasound aspects of the Ti-rads classification in the management of nodules. Results: We collected 235 patients out of 738 patients referred to the service for a cervical ultrasound, i.e. a frequency of 31.84% of cases. There was a female predominance with 95.7% of cases and a sex ratio of 0.04. The average age of our patients was 50 years. We found on cervical ultrasound: Isthmo-lobar glandular hyperplasia in 99 patients, i.e. a frequency of 42.1%. The Ti-rads 3 classification was the most represented in 69.4% of cases. The benignity criterion represented 85.6% of cases in our patients and the malignancy criterion represented 14.4% of cases. Conclusion: The precise description of a thyroid nodule provided by ultrasound (Ti-rads) is essential in the management of nodules.

The aim of this study was to clarify the interest of standard radiography in the management of Ollier’s disease. Observation: Enchondromas are benign lesions that may present on imaging with nonspecific features in children, and they are relatively large lesions, with frequent endosteal erosion and rare matrix mineralization. We report a case of predominantly right-sided multifocal enchondromatosis in a 5-year-old girl with no known medical history, diagnosed fortuitously on standard radiography during a trauma assessment and confirmed by histology. No sign of pain was noted after a 6-month follow-up. But the radiographic control noted signs of diffuse osteoarthritic remodeling in the surgical areas and early fusion of the growth cartilages. Conclusion: Ollier’s disease is rare, you have to know how to think about it in the face of fortuitous discoveries, especially at an early age. Enchondromas are benign lesions that may present on imaging with nonspecific features in children. In all cases, standard radiography is essential in the diagnosis and follow-up of Ollier’s disease.

Introduction: Retroperitoneal teratoma is a rare congenital tumour, representing only 1% to 10% of primary retroperitoneal tumors in children, far behind ovarian and testicular locations. There is a clear female predominance with a sex ratio of 3.4/1. The purpose of this study is to review the clinical manifestations, the mode of revelation of retroperitoneal teratoma, the diagnostic means and the anatomopathologic aspect of retroperitoneal teratoma, then to show the contribution and the limits of the various imaging examinations: ultrasound, CT and MRI in the diagnosis of retroperitoneal teratoma. Observation: We report the case of a mature retroperitoneal teratoma discovered in a 10-month-old male infant. The diagnosis evoked by ultrasound and abdominal CT was confirmed by histological study of the excised specimen. The postoperative evolution after 3 months was favorable in particular with no signs of recurrence. Conclusion: Retroperitoneal teratoma is a rare congenital tumour. The complete imaging assessment including ultrasound and computed tomography is necessary preoperatively in order to make the diagnosis and to clearly determine the relationship with the various organs. The anatomopathological study confirms the diagnosis of retroperitoneal teratoma. Tumor excision must be radical to avoid recurrence, which readily occurs in a malignant form. Even if the tumor appears benign, postoperative monitoring based on clinical, biological and radiological examination is essential.

Sirenomelia is a rare fetal malformation with more or less complete fusion of both lower limbs consistently associated with bilateral renal abnormalities. The positive diagnosis can be made antenatally by ultrasound during the first trimester of pregnancy but often before the 22 weeks of amenorrhea. The objective was to think about the possible diagnosis by ultrasound in front of the urinary anomalies and the ologiamnios during the morphological study of the second trimester of pregnancy. We report a case of sirenomelia in a 25-year-old lady as part of the routine prenatal assessment suspected and confirmed during the morphological ultrasound of the second trimester of pregnancy and confirmed after the termination of pregnancy in Mali in the Health Center of Reference of commune III of the district of Bamako. The morphological ultrasound made it possible to diagnose the malformation of the urinary tract, the amniotic fluid and to make the therapeutic decision of medical termination of pregnancy at the end of confirming the siren syndrome.

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.

Introduction: Bladder tumours are frequent, have a poor prognosis and are the second most common genitourinary tumour in men. In Mali, recent statistical data on the prevalence of bladder tumours show a progression with 6.71% in 2006. The euro scanner is used in the diagnostic workup. The work was initiated in order to specify the role of the scanner in the diagnosis of these tumors. Patients and Methods: Prospective descriptive study was carried out in the medical imaging department of Mali Hospital from February to November 2018. Were included any patient with a bladder tumour on euro scanner. The patients had benefited from a preliminary preparation and a renal biological assessment in order to eliminate renal insufficiency. Our examinations were performed with a Siemens 16-slice scanner. These were axial slices performed without, with iodine injection from the pulmonary base to the pubic bones. Results: We had collected 17 patients out of 541 scans i.e. a frequency of 3.76%. The age range of 21 to 40 years was 58.8% with an average age of 25 years. The antecedents (ATCD) found were urinary bilharzia (47%) and smoking (17%). The clinic was dominated by haematuria. It was associated with a bladder mass (52%) and dysuria (23.52%). The CT scan showed a budding appearance, a size greater than 3 cm (82%), infiltration of peri-vesical fat (47.05%), and adenopathy (94%). Associated lesions were: utero-hydronephrosis (58.82%) and metastases (bone and liver in 11.76% of cases each). Conclusion: They are frequent and the history of urinary bilharziasis remains the main risk factor in endemic countries. CT scans are essential in the management of this disease. The diagnosis of certainty remains histology.

Statistical Analysis for Assessing Randomness, Shift and Trend in Rainfall Time Series under Climate Variability and Change: Case of Senegal

引用

Journal of Geoscience and Environment Protection 2017年第13期5卷 31-53页

作者： Didier Maria Ndione Soussou Sambou Moussé Landing Sane Seydou Kane issa Leye Seni Tamba Mouhamed Talla cisse Hydraulic and Fluids Mechanics Laboratory (HFML) Department of Physics Faculty of Sciences and technology Cheikh Anta Diop University (UCAD) Dakar Senegal Polytechnic High School of Thies Thies Senegal

The main purpose of this study is to assess the climate variability and change through statistical processing tools that able to highlight annual and monthly rainfall behavior between 1970 and 2010 in six strategical raingauges located in northern (Saint-Louis, Bakel), central (Dakar, Kaolack), and southern (Ziguinchor, Tambacounda) part of Senegal. Further, differences in sensitivity of statistical tests are also exhibited by applying several tests rather than a single one to check for one behavior. Dependency of results from statistical tests on studied sequence in time series is also shown comparing results of tests applied on two different periods (1970-2010 and 1960-2010). Therefore, between 1970 and 2010, exploratory data analysis is made to give in a visible manner a first idea on rainfall behavior. Then, Statistical characteristics such as the mean, variance, standard deviation, coefficient of variation, skewness and kurtosis are calculated. Subsequently, statistical tests are applied to all retained time series. Kendall and Spearman rank correlation tests allow verifying whether or not annual rainfall observations are independent. Hubert’s procedures of segmentation, Pettitt, Lee Heghinian and Buishand tests allow checking rainfall homogeneity. Trend is undertaken by first employing the annual and seasonal Mann-Kendall trend test, and in case of significance, magnitude of trend is calculated by Sen’s slope estimator tests. All statistical tests are applied in the period of 1960-2010. Explanatory analysis data indicates upwards trends for records in northern and central and trend free for southern records. Application of multiple tests shows that the Kendall and spearman ranks correlation tests lead to same conclusion. The difference in tests sensitivity was shown by outcomes of homogeneity tests giving different results either in dates of the shift occurrence or in the significance of an eventual shift. A synthesis analysis of results of tests was carried o
