Thyroid Artery Erosion by Esophageal Cancer: Management with Interventional Radiology

Management of upper gastrointestinal bleeding because of erosion of vessels by esophageal cancer may be challenging. We present herein the angiographic images of a 49-year-old patient who was admitted with massive bleeding from a tumor-eroded inferior thyroid artery. Attempts to control the bleeding by means of flexible endoscopy and insertion of a Sengstaken–Blakemore tube had failed. The diagnosis was impressively demonstrated by multislice computed tomography with intravenous contrast in the arterial phase and multiplanar reconstructions (computed tomography angiography) and by digital subtraction angiography. The bleeding was successfully treated with superselective catheterization and coiling of the eroded vessel.

低能级体外冲击波碎石治疗肾鹿角形结石

目的探讨低能级体外冲击波碎石(extracorporeal shock wave lithortripsy,ESWL)治疗肾鹿角形结石的效果. 方法对18例鹿角形结石进行体外冲击波治疗.碎石能级1～3级,冲击次数1 800～3 000次,脉冲间隔60 ～80次/min,工作电压10～12.75 kV. 若结石直径>3 cm,在碎石前预先插入双J管,防止石街形成.对直径>4 mm的残余结石,再次行ESWL,直至结石完全消失. 结果所有病人耐受良好,治疗结束能自行回家.除1例碎石失败外,余17例经ESWL治疗成功.治疗3～9次,至完全排除结石.66例次(66/77,85.7%)术后有1～2次肉眼血尿.5例出现石街,长1.9～5.2 cm,4例石街经再次碎石成功,1例输尿管镜取石. 结论低能级ESWL治疗肾鹿角形结石是一种安全、有效的方法.     

后腹腔镜下离断式肾盂成形术

目的探讨后腹腔镜下肾盂成形术的临床疗效. 方法腹腔镜下通过后腹腔途径对9例肾盂输尿管连接部狭窄行离断式肾盂成形术并对技术进行改进. 结果 9例手术均获成功,手术时间110～240 min,平均160 min.术中出血量30～80 ml,平均50 ml.术后住院8～18 d,平均11.2 d.术后并发症:皮下气肿(合并阴囊气肿)1例,漏尿2例.术后1～10个月B超示术侧肾盂无积水5例,轻度积水2例,中度积水2例.3例术后5个月IVU显示吻合口通畅. 结论后腹腔镜肾盂成形术微创、效果好,值得推广.

Focal segmental glomerulosclerosis

Over the last 2 decades, we have learnt that focal segmental glomerulosclerosis (FSGS) is a ubiquitous phenomenon underlying the progressive deterioration of many different types of renal diseases in both pediatric and adult populations. FSGS may also be the primary renal lesion, whether in new disease entities such as glycogen storage disease and human immunodeficiency virus infection, or in idiopathic FSGS. Although the mechanism which triggers the development of primary FSGS still remains unknown, laboratory and clinical studies have identified several key pathophysiological events leading to end-stage renal disease. While therapeutic modalities have not changed remarkably, a recent study, although uncontrolled, demonstrated an impressive efficacy of intravenous steroid pulse therapy in inducing remission. Nevertheless, it remains largely unknown whether such a forced remission decreases the overall risk of developing chronic renal failure. Studies have revealed an important pathophysiological role of angiotensin and the therapeutic efficacy of angiotensin converting enzyme inhibitors in progressive loss of renal function in diseases where glomerulosclerosis is secondary; however, it remains to be verified whether these results hold true in primary FSGS. As a result of the improvement in allograft survival rate, the benefit of renal transplant outweighs the risk of recurrence of FSGS, hence transplantation continues to be a vital therapy for FSGS patients who have reached renal failure. Thus, FSGS is not one disease, but rather a range of lesions seen in many settings. The type of lesions and the patient's unique genetic factors contribute to prognosis, and also may dictate choice of optimum therapy.     

Influence of differences in tumor vascularity upon the effects of hyperthermia

Summary Utilizing two types of human renal carcinoma heterotransplanted in nude mice, we investigated the variations in hyperthermic effects (42.5°C for 30 min) caused by differences in tumor type with special reference to variations in tumor vascularity. In the hypovascular JRC1 strain, sporadic vascular dilation was observed throughout the tumors after heating. Destruction of tumor cells was observed mainly in the region of dilation. In the hypervascular JRC11 strain, homogenous vascular dilation was observed immediately after heating, mainly at the periphery of tumors. There was a decrease in the viability of cells in the center of the tumor. Therefore, the hypervascular tumors showed greater destruction mainly at the center where blood circulation was reduced. The range of necrosis was also greatly affected by the extent of vascular dilation caused by heating in hypovascular tumors.     

Regression of Pulmonary and Multiple Skeletal Metastases from Renal Cell Carcinoma by Nephrectomy and Alpha-interferon Therapy: A Case Report

We report a rare case of advanced renal cell carcinoma in apatient who showed complete resolution of metastases to thelung and bones after nephrectomy, partial jejunectomy and subsequentalpha-interferon therapy. The patient was a 54-year-old manwhose right lung and left femur metastases were detected beforenephrectomy. In the seventh week after nephrectomy, a partialjejunectomy was carried out because of the obstructive ileuscaused by intraluminal multiple metastases of the jejunum. Apathological fracture of the metastasized right humerus occurredsubsequently. After four months of intramuscular alpha-interferonadministration (3x106 units/day), however, x-rays revealed thecomplete disappearance of the metastatic lung shadow and a solidunion of the humerus, and there were no tumor cells in the femurspecimen resected at the subsequent reconstruction surgery ofthe left leg. Seven years have passed from onset, and the patientis still alive and disease free.
