摘要:

AbstractThirteen cases with liver cystic lesions, which were suspected to communicate with intrahepatic vessels on the basis of ordinary sonography, were examined by color Doppler flow imaging. By this method, blood flow within the cystic lesion was detected in 5 of these cases, and the communication to the intrahepatic vessel confirmed. Information about the hemodynamics of aneurysms was obtained. Two of these lesions were diagnosed as an aneurysmal porta‐hepatic venous fistula, another 2 as a portal venous aneurysm, and the remaining 1 as a hepatic venous aneurys

摘要:

AbstractUltrasonography and sialography of parotid glands were prospectively performed on 30 patients with Sjogren syndrome and follow‐up ultrasonography was done on 12 patients. Ultrasonography revealed multiple hypoechoic areas (MHA) 2 mm to 5 mm in diameter within the glands in 43% of the patients with intermediate severity of the disease, either homogeneous or slightly nonhomogeneous parotid glands in patients with early stage of the disease, and marked nonhomogeneous glands in patients with advanced diseases. Follow‐up ultrasonography showed MHA in one patient, reduction in nonhomogeneity in another three, and no interval changes in the remaining cases. Pathologic studies suggested that MHA represent enlarged parotid lobules replaced by lymphocytic infiltration. We suggest that MHA are characteristic of Sjogren syndrome and that ultrasonography is useful in following the course of the disease and response to treatm

摘要:

AbstractA technique of measuring femoral torsion employing reference lines on the posterior surface of the femur has been described. This technique was evaluated on 27 dry adult femora and then on 40 adult patients. The technique was found to be reliable and reproducible. The values of femoral torsion obtained by this technique is lower than that obtained when anterior reference lines are used.

摘要:

AbstractIn a double blind study, 20 gravidas with pre‐eclampsia were randomly allocated to treatment with either propranolol 120 mg/day or pindolol 15 mg/day for 7 days. Flow velocimetry was performed before and after treatment to assess the influence of these two regimens of beta blocker on the feto‐placental circulation. A continuous wave Doppler unit was used to measure umbilical and uterine artery flow velocity waveforms. The systolic/diastolic (A/B) ratio and the systolic minus diastolic divided by systolic (A‐B)/A ratio (resistance index) were used as indexes of blood flow resistance in the umbilical and uterine arteries, respectively. A resistance to flow in the uteroplacental circulation was significantly less in patients treated with pindolol compared to those treated with propranolol (P<0.01). The same pattern was also found in umbilical velocimetry, although the statistical significance was borderline (P= 0.06). Although both drugs were equally effective in reducing blood pressure at rest, their effect on the peripheral resistance was different. Pindolol appears to act in part through a peripheral vascular mechanism. Our data support this assumption because the flow in the uteroplacental bed, as reflected by a decrease in resistance index, improved when patients were treated with the drug pin

摘要:

AbstractIntrahepatic duct (IHD) stone is a common disease in Taiwan. In some cases, left IHD stones cannot be demonstrated by endoscopic retrograde cholangiography (ERC) or even by percutaneous cholangiography (PTC). This study was designed to evaluate the efficacy of sonography in demonstrating left IHD stones in poorly opacified left IHD by either ERC or PTC.Of 109 patients with hyperechoic nodular lesions in either the dilated left IHD or atrophic left lobe of the liver, with or without acoustic shadows, 49 patients were excluded because they refused further study. Among the remainder (60 patients), 33 patients had good opacification of left IHD in ERC or PTC. Stones were seen in 31 patients, and tumor obstruction in 2 patients. Twenty‐seven patients had complete or partial absence of the left IHD in cholangiograms. Stones were found at surgery in 23 patients and by CT scan in 3 patients. Mucin‐producing cholangiocarcinoma was found in 1 patient.The positive predictive value of the demonstration of stones in left IHD by ulrasound was 95% (57/60). Only 15% of patients with atrophy of the left hepatic lobe and stones were demonstrated by sonogram in this series. We conclude that the detection of left IHD stones by ultrasound in patients with poor opacification of the left IHD in cholangiograms is reliable proced
