Objectives: To demonstrate the contribution and relevance of ETFs through the study of 1000 examination reports carried out in the medical imaging departments of the OUAGADOUGOU CHU. Material and method: Analytical descriptive study with retrospective collection, extended from 1st January 2020 to 1st January 2022. Results: Of the 1000 transfontanellar ultrasound reports, the mean age of patients was 7.61 +/ 7.5 days, with extremes of zero and 28 days. Sex was specified in 989 cases. Males accounted for 54.49% and females for 45.51%. 555 transfontanellar ultrasound were performed in 2020. 441 in 2021 and 4 in 2022. 61.9% of transfontanellar ultrasound were performed at the Bogodogo University Hospital, 205 at Charles de Gaulle and 176 at Tengandogo. Indications for transfontanellar ultrasound were dominated by neonatal distress (65.8%), followed by convulsions (10.2%) and prematurity (9.1%). Transfontanellar ultrasound was normal in 570 cases (57%) and abnormal in 430 cases (43%). Abnormalities were dominated by haemorrhage and ischaemic lesions in 66.28% (285) and 21.63% (93) of cases respectively. In the group of normal transfontanellar ultrasound, neonatal distress represented 59.65% of indications and prematurity 10.7% of indications. As for abnormal transfontanellar ultrasound, neonatal suffering accounted for 73.95% of indications and convulsions for 12.56%. The average age ofpatients with an abnormal transfontanellar ultrasound was 8.74 days +/ 7.89 days. The indication for investigations was relevant in 42.2% of cases and irrelevant in 57.8%;of the transfontanellar ultrasound with relevant indications, 0.71 were normal and 99.29 abnormal;of the transfontanellar ultrasound with irrelevant indications, the transfontanellar ultrasound was normal in 98.1% and abnormal in 1.9%. Conclusion: Transfontanellar ultrasound is an important part of ultrasound in current practice. Haemorrhage, anoxic-ischaemic lesions and hydrocephalus are the most frequent pathologies fou

Objective: The aim of our study was to propose a solution for rationalizing requests for ultrasound examination and CT scan in suspected acute appendicitis, based on use of the Alvarado score. Patients and Methods: We included in our study all patients consulting for pain of the right iliac fossa, whatever their age and sex, who had been diagnosed with acute appendicitis and who had undergone appendectomy. We used the Alvarado scoring system, based on clinical items and laboratory measurements, to diagnose appendicitis. Results: One hundred eleven patients, of whom 77 were men (69.4%) and 34 were women (30.6%), with a sex ratio of 2:2.6, were included. Mean age was 31.29 ± 1.31 years, with a range of 1 to 81 years. The diagnosis of definite appendicitis was established in 54 patients (48.6%). Abdominal ultrasound examination had been performed in 80 patients (72.1%). It established a diagnosis of appendicitis in 69 patients (86.2%), while in 11 patients (13.8%) the appendix was described as normal or was not visualized. Conclusion: Our study demonstrated good agreement between peroperative diagnosis and the result of the Alvarado score applied a posteriori. Ultrasound was not always contributory to the diagnosis of acute appendicitis. It could be reserved for patients whose clinical and laboratory score indicated that appendicitis was unlikely.

世界核心医学期刊文摘（儿科学分册） 2006年第4期2卷 22-22页

作者： Gonalves-Matoso V. Renella R. Gudinchet F. D. Lepori 朱新菊 service de radiodiagnostic et de Radiologie Interventionnelle CHU Vaudois 46 rue du Bugnon 1011 Lausanne Switzerland

Undifferentiated sarcoma of the liver is a rare primary tumor of childhood: only about 150 cases have been reported in the literature. Case-report. - A 10 year-old girl was admitted because of diarrhea and weight loss. Sonography, then CT-scan and MRI showed a large tumor of the liver. Comments. - In the differential diagnosis of primary liver tumors in children, one should think about undifferentiated sarcoma of the liver, especially if imaging shows haemorrhagic foci and if sonography and CT/MRI display a discordant appearance. Survival has improved in the last decade due to agressive surgery and intensive chemotherapy.
