Hemangioma of the Prostatic Urethra: Hematospermia and Massive Postejaculation Hematuria with Clot Retention

The case of a 53-year-old man with hematospermia and massive postejaculation hematuria that caused urinary retention is described. This is the sixth case in the English and Japanese language literature. Cystourethroscopic examination revealed that a solitary raised tumor was present just distal to the vermontanum, and that bleeding was from its apex. Histologic examination of an excisional biopsy sample showed features compatible with hemangioma.     

Amyloidaceous ulcerated gingival hyperplasia: a newly described entity related to ligneous conjunctivitis

Gingival hyperplasia may be genetic, may be acquired as a consequence of exposure to drugs and other agents or may appear as part of a more widespread disorder. Five patients who acquired gingival hyperplasia due to amyloidaceous deposits staining only for fibrin are presented. This appears to be a new entity related to ligneous conjunctivitis.     

维拉帕米灌注治疗前列腺术后膀胱痉挛性疼痛的临床疗效观察

为探讨前列腺术后膀胱痉挛性疼痛的药物治疗效果，将２６例前列腺增生行耻骨上经膀胱前列腺摘除术后频繁发作膀胱逼尿肌无抑制性收缩导致膀胱痉挛性疼痛者，按随机抽样法分为两组，第１组１５例接受维拉帕米膀胱灌注治疗，第２组１１例作为对照，不用任何可能影响下尿中功能的药物。     

Influence of Osteoarthritis on Serum Marker Levels of Bone Formation and Resorption in Patients with Benign Prostatic Hypertrophy

Background :
The aim of this study was to investigate the influence of osteoarthritis of lumbar vertebrae on serum bone formation and resorption marker levels of patients with benign prostatic hypertrophy (BPH).
Methods :
Serum levels of carboxyterminal propeptide of type I procollagen (PICP), alkaline phosphatase (ALP), carboxyterminaltelopeptide of type I collagen (ICTP), and prostate-specific antigen (PSA) were examined in 40 patients with BPH, and the presence of osteoarthritis at the lumbar vertebrae of the patients was evaluated by plain x-ray-p.
Results :
Findings of osteoarthritis were observed in 23 of the 40 patients (58%), and 10 of the patients had severe osteoarthritis (involving at least 2 lumbar vertebral bodies). The serum levels of PICP, ALP, ICTP, and PSA of the patients without osteoarthritis findings were not different from those of the patients with osteoarthritis or severe osteoarthritis.
Conclusion :
The influence of osteoarthritis on serum bone formation and resorption marker levels of patients with BPH appears to be rather slight, if there is any influence at all.     

Angiolymphoid hyperplasia with eosinophilia: report of a large-sized scalp lesion

In this report, a case is presented with large recurrent, benign, vascular and proliferative lesion on the scalp. Complete surgical excision of the tumor mass and split thickness skin grafting of the defect had favorable results with no recurrences after 24-month follow-up.     

Lymphoid follicular hyperplasia–a distinctive feature of diversion colitis

Diversion colitis refers to the inflammatory changes that occur in the defunctioned segment of the large intesting following diversion of the faecal stream. We report the histological features in the defunctioned rectums from seven patients: one each with severe constipation and Behcet's disease, two with Crohn's disease with rectal sparing and three with ulcerative colitis. The appearances of diversion colitis in a previously normal rectum are compared with diversion colitis with superimposed inflammatory bowel disease. Lymphoid follicular hyperplasia was found in all cases. This was marked in patients with inflammatory bowel disease. with or without initial rectal involvement. Other changes comprised surface epithelial degeneration and ulceration, mucosal inflammation including crypt abscesses, and crypt branching. Inflammatory and crypt changes were mild, except in ulcerative colitis where changes were marked and resembled those of the proximal colon. Lymphoid hyperplasia is a distinctive feature in diversion colitis. The term follicular proctitis, previously used to indicate chronic ulcerative colitis exclusively, should be re-examined.     

Establishment of a prostatic hyperplasia model with beagle dogs

Objective: To establish a prostatic hyperplasia model with beagle dogs. Methods: Twenty-four male beagle dogs, 2 years of age, were divided into the treatment and control groups at random and were administrated testosterone propionate (TP) i.m. two months after castration. Three treatment groups were set with the doses of TP at 0.8 mg/kg, 2.5 mg/kg and 7.5 mg/kg, respectively, and the control was given the same volume of vehicle. Two months later, half of the animals were killed and sera samples were obtained. The wet weight and volume of prostate were measured. The dihydro testosterone (DHT) level of the serum and prostate were determined with the commercial radioimmunoassay (RIA) kit. The prostate was sectioned, fixed and stained with hematoxylin and eosin. Pictures were taken with a digital camera under the microscope and were analyzed with a computer for the epithelial cell height and the acinar luminal area with micro image analysis software. The prostate volume was measured with ultrasonic diagnost     

前列腺癌患者PSA、PSAD、PSAT测定

目的：探讨前列腺特异抗原（PSA）及前列腺特异抗原密度（PSAD）、前列腺特异抗原移行区密度（PSAT）作为前列腺癌肿瘤标志物的临床价值。方法：选择前列腺癌患者30例、前列腺增生患者30例、健康志愿者20例，采用放射免疫法检测PSA并计算PSAD、PSAT，比较3组间的变化情况。结果：前列腺增生组PSA升高，与对照组相比差异有统计学意义（P＜0．05），前列腺癌组PSA、PSAD、PSAT均升高，与对照组及前列腺增生组对比差异有统计学意义（P＜0．001）。结论：PSA作为前列腺癌肿瘤标志物有重要临床价值，但单纯测定血PSA含量有时不易区分前列腺增生与前列腺癌；PSAD、PSAT在前列腺增生与前列腺癌的鉴别诊断中优于PSA。

哈乐在良性前列腺增生伴急性尿潴留中的应用

目的 :探讨α1A肾上腺素能受体阻滞剂哈乐 (tamsulosin)对良性前列腺增生 (BPH)伴急性尿潴留病人的治疗作用。方法 :对 72例BPH伴急性尿潴留病人采用随机、对照研究 ,分为治疗组和对照组。病人均行保留导尿 ,口服抗生素治疗。治疗组加用哈乐 0 .4mg ,1次 /d ,连续服用 3次。 72h后拔除导尿管。　结果 :拔除导尿管后 4 4 % (32 / 72 )的病人能自行排尿。有效率治疗组为 6 1% (2 2 / 36 ) ,对照组为 2 8% (10 / 36 ) ,两组比较差异有显著性 (P <0 .0 1)。　结论 :对BPH伴急性尿潴留应用哈乐治疗 ,可提高早期拔除导尿管后病人自行排尿的成功率 ,且疗效与前列腺体积大小无关。
