A 2 month old boy with Kawasaki disease developed the rare complication of abdominal aortic aneurysm (AAA). He was followed up over 7 years by ultrasonography (2D-ECHO) with and without Doppler flow evaluation, angiography and computed tomography. Calcification was noted 33 months after the onset of the disease but the aneurysm did not decrease in size. 2D-ECHO was adequate for evaluating the size of an aneurysm, but did not show thrombus formation or calcification. Doppler flow studies did not show abnormally high blood flow velocities either at the inflow or outlet of aneurysms, which are indicative of stenosis. On the other hand an abdominal aortogram provided information regarding the luminal shape and abnormalities in flow pattern suggestive of thrombus formation. Fluoroscopy cannot demonstrate calcification in the early stages. Computed tomography (CT) was the imaging method of choice for the evaluation of obstructive or calcific changes; an organizing thrombus was clearly demonstrated and early detection of calcification was possible. 相似文献

Immunological abnormalities frequently observed in patients with primary biliary cirrhosis are considered to be related to the pathogenesis of this disease. We performed a prospective trial to evaluate whether immune mechanisms play a role in the effectiveness of ursodeoxycholic acid (UDCA) therapy. Fifteen female patients with primary biliary cirrhosis were followed for 1 year and were then treated with UDCA (600 mg/day) for another year. Laboratory tests, including peripheral blood lymphocyte subsets assessed by dual colour fluorescence analysis using monoclonal antibodies against respective T cell markers, were evaluated at the beginning of the study, at the start of therapy and at the end of therapy. In primary biliary cirrhosis, the proportion of cytotoxic T cells, suppressor inducer T cells and αβ-receptor bearing T cells were significantly lower than in healthy controls. No significant changes were observed in the proportions during the year before the therapy. These reductions, however, recovered to normal ranges after 1 year of UDCA therapy. These changes were associated with an improvement in the serum levels of aspartate aminotransferase, alkaline phosphatase, γ-globulin and IgM. The close correlation between the improvement in the imbalance of lymphocyte subsets after the therapy and the clinical status suggests that an immunological process may play a role in the effectiveness of therapy in primary biliary cirrhosis. 相似文献

Subcutaneous seeding of small hepatocellular carcinoma after fine needle aspiration biopsy 总被引:1,自引:0,他引:1
NOBUO YAMADA HARUHIDE SHINZAWA KATSUAKI UKAI HIROTO WAKABAYASHI HITOSHI TOGASHI TSUNEO TAKAHASHI NOBUO SEO SHUICHI ISHIYAMA MASARU TSUKAMOTO SHIGEMI FUYAMA 《Journal of gastroenterology and hepatology》1993,8(2):195-198
Ultrasonically guided fine needle (21 gauge) aspiration biopsy (FNAB) was performed on a patient with a hepatocellular carcinoma (HCC) measuring 1.5 × 1.5 cm in segment VI of the liver. The tumour was located just beneath the liver surface. Subsegmentectomy of segment VI was performed. Twelve months after the biopsy and 10 months after the operation, levels of alpha-fetoprotein (AFP) and protein induced by Vitamin K absence or antagonist-II (PIVKA-II) increased gradually without any evidence of recurrence of HCC in the liver. Thirteen months after the biopsy, the patient palpated a hard subcutaneous nodule 1.5 cm in diameter in the right lower anterior chest wall at the insertion site of the biopsy needle. A subcutaneous tumour was excised and histological examination revealed moderately differentiated HCC. The levels of AFP and PIVKA-II normalized thereafter. These tumour markers were therefore useful for diagnosing the subcutaneous nodule as a metastatic HCC. The patient is currently doing well without further recurrence of HCC or needle-tract seeding 23 months after subsegmentectomy and 11 months after excision of the subcutaneous tumour. 相似文献

Three human brain tumors, oligodendroglioma, glioblastoma andmalignant histiocytoma, were successfully transplanted intonude mice. In the case of oligodendroglioma, various experimentaltherapeutic agents were tried on the transplanted tumor of thenude mice in order to select the most effective agent. Vincristinewas found to be the most potent. A total dose of 16 mg of vincris-tinewas also effective in the donor patient. Although the patientdied of a head injury soon after the vincristine therapy, thisreport is worth publishing from the viewpoint of a successfulclinical trial based on the results of experimental therapyof a human glioma transplanted into nude mice. 相似文献

Small angiomyolipoma of the liver diagnosed by fine-needle aspiration biopsy under ultrasound guidance 总被引:1,自引:0,他引:1
NOBUO YAMADA HARUHIDE SHINZAWA NAOHIKO MAKINO TAKAAKI MATSUHASHI SATOSHI ITASAKA TSUNEO TAKAHASHI SHIGEMI FUYAMA 《Journal of gastroenterology and hepatology》1993,8(5):495-498
The first reported case of small hepatic angiomyolipoma to be diagnosed by fine-needle aspiration biopsy (FNAB) is described. A 53 year old man presented with a tumour in segment VI of the liver measuring 0.9 × 0.8 cm. The tumour was hyperechoic on ultrasound examination, showed relatively low density (+ 33 Hounsfield units) on computed tomography (CT), and was hypervascular on angiography. Computed tomography during arterial portography demonstrated a perfusion defect. Magnetic resonance imaging (MRI) revealed high intensity by both T1- and T2-weighted imaging. Diagnosis could not be obtained by these imaging modalities, but it was established successfully by FNAB under ultrasound guidance. Histologically, the tumour was an angiomyolipoma made up of three components: blood vessels, smooth muscle and fatty tissue. Surgery is unnecessary for this benign condition, and the patient has been followed up. Ten months later, the patient is currently doing well without growth of the hepatic angiomyolipoma. 相似文献
