According to this study, numerous anatomical variations of the LFCN at the thigh should be considered when performing anterior approach to the hip joint. Different mechanisms of injury during surgery should be considered especially during minimally invasive total hip replacement, such as section of the gluteal or the femoral branch where it crosses the anterior margin of the TFL or stretching of the femoral branch due to retractors positioned into the intermuscular space between sartorius and TFL. According to the map of "danger zones" reported, the author policy consists of positioning the skin incision as lateral and distal to the ASIS as possible.
• Whole-body post-mortem computed tomography (PMCT) is an effective non-invasive method. • Whole-body PMCT is essential for detecting child abuse in unexpected death. • There is concordance on cause of death between PMCT and autopsy. • Whole-body PMCT could improve autopsy through dissection and sampling guidance. • PMCT shows findings that may be relevant when parents reject autopsy.
Biodistribution of iodine-131-labeled Lipiodol Ultra-Fluide (I-131 LUF) injected into the hepatic artery was studied scintigraphically in 47 patients with hepatocellular carcinoma (n = 23), hepatic metastases (n = 14), or normal livers (n = 10). The investigation was extremely well tolerated. I-131 LUF concentrated mainly in the liver (L) and the lungs (l), with L/L + l activity ratios greater than 75% for all three groups of patients. I-131 LUF distribution was homogeneous in normal livers and heterogeneous in cirrhotic livers. I-131 LUF concentrated in the tumor with a tumorous (T) to nontumorous (NT) activity ratio (T/NT) of 4.3 +/- 3.6 for hepatocellular carcinoma and 2.4 +/- 0.7 for hepatic metastases. The effective half-life of I-131 LUF is more than 4.5 days for the three groups. It was eliminated mainly through the urine. Clearance from tumor is slower than from normal liver, as shown by the increase in T/NT at day 18. Biodistribution did not change in patients who had a second injection, which indicates that there is no saturation phenomenon. The results of this study suggest that LUF may be considered as a potential carrier vehicle for therapeutic agents.
Foetal intra-abdominal umbilical vein varix is rare. Colour Doppler ultrasonography helps distinguish this vascular anomaly. A detailed anatomic scan must be performed to exclude associated anomalies: forms associated with additional complications are found in 29 to 35% of the cases. Intra-uterine foetal demise (IUFD) is a complication of umbilical vein varix. However, recent studies are more reassuring. When foetal intra-abdominal umbilical vein varix is isolated, there is no reason to change the management of the pregnancy. Foetal sonographic follow-up is recommended, focusing on an increase in the size of the varix and the appearance of a clot. A particular clinical form, connecting the umbilicus to the extra-hepatic portal vein should be known, because of a high risk of thrombosis. On the basis of this finding, postnatal monitoring by ultrasound is necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
