Introduction: neonatal asphyxia (nA) is one of the most likely causes of neuro-developmental abnormalities in children. In Mali it is responsible for half of the early deaths and the third of neonatal mortality. Updated data would help understand and improve intervention strategies to reduce mortality. Objective: It is the study of epidemiological and clinical characteristics, the immediate outcome and the factors associated with newborn (nB) mortality with nA. Material and Methods: This was a prospective cross-sectional study from June 27th to September 3rd 2016 about the nBs admitted for nA in the Hospital Teaching Gabriel Touré of Bamako. The clinical and biological data including the prognosis were collected from the health records of women, the liaison sheets and the medical file. The analysis was done using the software Epi info version 3.5.1. Results: 76 nBs were included which represented 23.45% of hospitalizations. The majority (89.5%, n = 68) were admitted to less than 24 hours of life for nA grade III according to the Sarnat classification (43.4%, n = 33). The average age of mothers was 24.17 ± 5.5 years. Almost half (41.3%, n = 31) were primigravida. The most common obstetrical event was dystocia (64.5%, n = 49). The prognosis was poor in grade III anoxia in our patients (56%) of deaths. Conclusion: The périnatal anoxia (PA) is a major health issue in Mali because of its frequency and severity. Monitoring of pregnancies, delivery assisted by skillful and qualified personnel, mastery of neonatal resuscitation techniques are good means of prevention.

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.

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.

Introduction: Radiology and medical imaging examinations bring together the means of acquiring and restoring images of the human body from different physical phenomena such as the absorption of X-rays, nuclear magnetic resonance, reflection of ultrasound waves or radioactivity, with which we sometimes associate optical imaging techniques such as endoscopy. The objective of our study was to study the profile of radiological examinations in the radiology and medical imaging department of the “KAlAlE” medical clinic. Methodology: This was a descriptive, prospective study that took place over a period of six (6) months in the radiology and medical imaging department of the “KAlAlE” medical clinic and the centers of health of communes III and IV of Bamako in Mali. Data collection was carried out on a survey form. The parameters studied were sociodemographic data, clinical data, radiological data. Results: We recorded 6030 radiology examinations of which 19% of the examination frequency cases came from the “KAlAlE” medical clinic and 81% of the cases were referrals from the reference health centers of communes III and IV. There were 1500 X-rays or 24.9% of cases including 54% cases of bone X-rays;5% of cases of skull and face X-rays;5% of cases of Intravenous Urography (IVU);4% of cases of Hysterosalpingography (HSG);3% of cases of Retrograde Ureterocystography (UCR) and 1% of cases of X-ray of the Abdomen without preparation (ASP). We found 4530 ultrasounds or 75.1% of cases. Conclusion: Medical imaging has become essential in the study of the human body and now constitutes an essential tool for the detection and treatment of most pathologies, from simple fractures to the most serious tumors.

作者： Zunli lu Rosalind E.M.Rickaby Jonathan l.Payne Ashley n.Prow Department of Earth & Environmental Sciences Syracuse University Department of Earth Sciences University of Oxford Department of Earth and Planetary Sciences Stanford University

Atmospheric carbon dioxide and oxygen concentrations are partially linked via the geological cycle of organic carbon （Fig. 1A–C; e.g. CO2+H2O■CH2O+O2）. The history of these two biologically active components, controls on their concentrations, and implications for the complexity of the biosphere and habitability of Earth have been hotly debated, but are generally considered independently.
