Skin Perfusion Pressure Is a Prognostic Factor in Hemodialysis Patients
Peripheral arterial disease (PAD) is common in hemodialysis patients and predicts a poor prognosis. We conducted a prospective cohort study to identify risk factors for PAD including skin perfusion pressure (SPP) in hemodialysis patients. The cohort included 373 hemodialysis patients among 548 patients who received hemodialysis at Oyokyo Kidney Research Institute, Hirosaki, Japan from August 2008 to December 2010. The endpoints were lower limb survival (peripheral angioplasty or amputation events) and overall survival of 2 years. Our results showed that <70 mmHg SPP was a poor prognosis for the lower limb survival and overall survival. We also identified age, history of cardiovascular disease, presence of diabetes mellitus, smoking history, and SPP < 70 mmHg as independent risk factors for lower limb survival and overall survival. Then, we constructed risk criteria using the significantly independent risk factors. We can clearly stratify lower limb survival and overall survival of the hemodialysis patients into 3 groups. Although the observation period is short, we conclude that SPP value has the potential to be a risk factor that predicts both lower limb survival and the prognosis of hemodialysis patients
Prognosis of Elderly Japanese Patients Aged ≥80 Years Undergoing Hemodialysis
Although the number of elderly patients requiring dialysis has increased, data regarding the prognosis of elderly patients undergoing hemodialysis are limited. In the present study, prognosis in Japanese hemodialysis patients aged ≥80 years was evaluated. From January 1988 to July 2013, 1144 consecutive patients with end-stage renal disease required renal replacement therapy at our institution; of these, 141 were aged ≥80 years. These patients’ charts were retrospectively reviewed for relevant clinical variables and survival time. The life expectancies table from the National Vital Statistics database was used, and prognostic factors were assessed by multivariate analysis. In total, 107 deaths (76%) were recorded during the study period. The median survival time and estimated life-shortening period in the patients were 2.6 years and −5.3 years, respectively. Eastern Cooperative Oncology Group Performance Status and hemoglobin level were revealed as prognostic factors in the multivariate analysis. Estimates of prognosis and prognostic factors may provide useful information for physicians as well as elderly patients with end-stage kidney disease

Prognostic benefit of surgical management in renal cell carcinoma patients with thrombus extending to the renal vein and inferior vena cava: 17-year experience at a single center
Solitary Fibrous Tumor of the Prostate Which Was Initially Misdiagnosed as Prostate Cancer
Solitary fibrous tumor (SFT) of the prostate is a very rare tumor. We report a case of 65-year-old man with SFT of the prostate which was initially misdiagnosed as prostate cancer. Finally, we performed total prostatectomy and the tumor was histologically diagnosed as SFT of the prostate. The patient’s clinical course has progressed favorably with no obvious recurrence 18 months postoperatively
Surgery without Blood Transfusion for Giant Paraganglioma in a Jehovah's Witness Patient
A retroperitoneal tumor was identified in a 57-year-old female belonging to Jehovah's Witnesses during a health check. Subsequent examination led to the suspicion of a right pheochromocytoma. The patient wished to be treated by bloodless surgery and consulted our hospital after being refused surgery by several hospitals. She signed a liability waiver for blood transfusion refusal. After obtaining consent for diluted autotransfusion and preoperative administration of erythropoietin, the surgery was scheduled. The tumor was attached to the inferior vena cava and left renal vein and engulfed the right renal artery and vein. The tumor and right kidney were removed en bloc. Operative time was 8 h and 18 min, with 1,770 ml of blood loss. The histopathological diagnosis was paraganglioma with the normal adrenal gland within the border of the tumor. The patient was discharged from the hospital with no postoperative complications
