The CT appearance of the adrenal glands was investigated in 30 patients with congenital renal anomalies (17 cases of unilateral renal agenesis, 11 of inferior ectopy, and 2 of crossed fused ectopy). The ipsilateral adrenal was clearly identified in 83% of these patients; in all of them, the adrenal was a paraspinal disk-shaped organ, which appeared linear on CT. Conversely, the adrenals retained their normal shape in a control group of 20 patients with acquired renal atrophy or prior simple nephrectomy. 相似文献

We compared hospital length of stay (LOS) and costs between (1) minimally invasive total hip surgery (MIS) combined with an active hip pathway (AHP) and (2) long incision total hip surgery (LIS) with a passive hip pathway (PHP). A prospective consecutive cohort of 214 MIS/AHP patients was compared to a concurrent cohort of 265 LIS/PHP patients. The MIS/AHP cohort had significantly decreased LOS (1.5 days vs. 3.8 days, P < .001) and hospital costs ($12.8 thousand vs. $16.7 thousand, P < .001). The complication rates were similar for MIS/AHP and LIS/PHP. We conclude that, compared to LIS/PHP, MIS/AHP significantly shortened LOS by an average of 2.3 days, and significantly reduced hospital costs by an average of $3.9 thousand per patient. 相似文献

Opinion statement Endoscopic therapy for biliary tract disease in patients with end-stage liver disease (ESLD) before liver transplantation
is safe and effective. Reported results in patients with choledocholithiasis, primary sclerosing cholangitis (PSC), and symptomatic
gallbladder diseases are encouraging. Prompt recognition and appropriate treatment of symptomatic gallbladder and bile duct
disease are important in reducing morbidity and mortality in these high-risk patients while they await liver transplantation.
Confirmation of tissue diagnosis of cholangiocarcinoma in patients with sclerosing cholangitis is still difficult. Better
screening tools and diagnostic methods are necessary for early detection. Because liver transplantation is the only definitive
therapy for patients with advanced cirrhosis, maintenance of their candidacy with either endoscopic or radiologic therapeutic
interventions is warranted until transplantation. Endoscopic therapy is the preferred method when feasible. If necessary,
percutaneous transhepatic biliary drainage (PTBD) is a viable alternative because both avoid the attendant risks of surgery
in a high-risk population with advanced liver disease. 相似文献

An immunohistochemical study of keratin expression in ameloblastoma from a Kenyan population 总被引:4,自引:0,他引:4
OBJECTIVES: Ameloblastomas appear to exhibit biological heterogeneity and, except in the case of malignancy, histological appearances that do not always allow their behaviour to be predicted. The aim of this study was to assess keratin expression in African ameloblastomas and to correlate this with their clinical and histological features. MATERIALS AND METHODS: Expression of simple keratins 7, 8, 18 and 19; cornification keratins 1 and 10; basal and differentiation keratins 5 and 14 and hyperproliferation-related keratins 6 and 16 in 14-39 cases of ameloblastoma was assessed by immunohistochemical methods. RESULTS: There was patchy expression of keratin 7 in the suprabasal and stellate reticulum-like cells in some cases. All cases showed similar weak expression for keratins 8 and 18 in suprabasal and stellate reticulum-like cells but none showed keratin 1 or 10 expression. There was intense expression of keratins 5, 14 and 19 by all tumour cells suggesting that they may retain basal cell characteristics with a potential for proliferation. No consistent relationship was seen between histological types and keratin expression pattern. However, keratins 6 and 16, expressed by suprabasal and stellate reticulum-like cells, showed a marked variation within and between cases, with the highest levels of expression in squamous strands. CONCLUSIONS: We propose that squamous strands may represent the sites of most active growth within individual tumours and expression of keratins 6, 16 and 19 may be predictors of rapid growth. There is a need for further investigation of this in longitudinal clinical studies. 相似文献
