The prevalence of antibodies against hepatitis C virus (HCV) was investigated in 96 patients with hepatocellular carcinoma, 106 patients with liver cirrhosis without evidence of cancer, and 177 controls without liver disease. 75% of patients with hepatocellular carcinoma had HCV antibodies (anti-HCV), a significantly higher proportion than that observed in(More)
This paper presents a new tele-operated robotic chain for real-time ultrasound image acquisition and medical diagnosis. This system has been developed in the frame of the Mobile Tele-Echography Using an Ultralight Robot European Project. A light-weight six degrees-of-freedom serial robot, with a remote center of motion, has been specially designed for this(More)
Congenital cystic dilation of the intrahepatic bile ducts (Caroli's syndrome) is a rare cause of chronic cholestasis and hepatolithiasis in young adults. Long-term prognosis is poor even with surgical drainage. We treated twelve patients who had Caroli's syndrome and intrahepatic stones with ursodeoxycholic acid (UDCA), 10-20 mg/kg daily. The duodenal bile(More)
The routine clinical assessment of lipodystrophy in HIV-1-infected patients is hindered by the absence of easy and reliable methods to measure regional fat. We used sonography to measure subcutaneous fat thickness at three reference skin points (periumbilical, brachial, and malar) and intra-abdominal fat thickness in HIV-1-infected patients with and without(More)
The temporomandibular joint (TMJ) is a synovial joint. The TMJ is a freely movable articulation between the condyle of the mandible and the squamous portion of the temporal bone at the base of the skull. The bilateral articulation of the mandible to the cranium implies that the left and right TMJs must act as a single unit. Physical examination alone is(More)
