Testicular biopsy has been known as very useful diagnostic procedure for the male infertility. For the past 9 months percutaneous testicular biopsy procedures were attempted on 64 patients with azoospermia or atrophic testis using a new Tru-Cut biopsy needle. In addition surgical testicular open biopsy procedure on one side and percutaneous testicular needle biopsy procedure on the other side were performed in comparison with two techniques. Biopsy specimens were fixed in Bouin solution. They were stained and histologically examined. Results were summarized as follows: Numbers of seminiferous tubules obtained by needle biopsy technique were found to be fewer than that of the tubules obtained by open biopsy technique. But diagnostic accuracy was not compromised by the needle biopsy technique. There was no bleeding either from the testis or scrotum, no extusion of testicular tissue from the puncuate site. In conclusion percutaneous testicular biopsy using Tru-Cut biopsy needle has been proved to be simple, time saving, less expensive and accurate method for testicular biopsy.

Chronic cavities of the dorsum of the foot often have bare bone and are unsuitable for free skin grafting. Local Flaps are often impossible because of surrounding scar tissue and dead space. A simple method is presented; it consists of the excision of the lesion, filling the cavity by a two staged random-pattern de-epithelialised turn over flap, and skin graft.

PURPOSE: To evaluate the characteristic MR findings in injury of the anterior cruciate ligament (ACL) with associated bony lesions. MATERIALS AND METHODS: We reviewed MR findings and the corresponding arthroscopic or operative results of 48 patients with ACL injuries, and evaluated ACL signal intensity and contour. In associated bony lesions, we determined the location of avulsion fracture and bony bruise. RESULTS: Cmplete ACL tears were seen in 27 cases, partial tears in 13, and avulsion injury in eight. Complete tears showed heterogeneously increased signal intensity with contour bulging in ten cases (37 %), and combined bony lesion in 14 (52 %). ACL with a thin continous low signal intensity band surrounding heterogeneously-increased signal intensity suggested partial tears, and was seen in three of 13 proven cases (23 %) of partial ACL tears ; combined bony lesion was seen in four such cases (31 %). There were eight cases of avulsion fracture ; the most frequent site was the anterolateral portion of the tibial spine (n=6). The most frequent sites of bony lesion were at the midportion of the lateral femoral condyle (n=6), and the posterior portion of the lateral tibial plateau (n=6) ; the next most frequent site was the anterior portion of the lateral tibial plateau (n=5). CONCLUSION: Tearing of the ACL was seen on MRI as ligament discontinuity, and heterogeneously increased signal intensity with ACL contour bulging. The most frequent sites of associated bony lesions were the midportion of the lateral femoral condyle, and the posterior portion of the lateral tibial plateau. In associated bony lesions, bony contusion suggested ACL tearing, but avulsion fracture suggested ligament avulsion injury without tear.

BACKGROUND: Alpha-blocker can result in falling and fractures because of adverse effect such as orthostatic hypotension due to vasodilatory effect. We investigated the association between the alpha-blocker and the risk of osteoporotic hip fractures using a nationwide claim database. METHODS: We identified 1,051,651 men 65 years of age or older who had prescription records of alpha-blocker from nationwide medical claim database, from 2007 to 2012. Alpha-blockers were classified as non-specific general (NSG), non-specific slow-release (NSSR), uro-specific general (USG), and uro-specific slow release (USSR). RESULTS: Total of 6,553 hip fractures were observed. The incidences of hip fracture within 1 year were higher than those of the reference periods in all type of alpha-blocker. Hazard ratio peaked at early period of alpha-blocker, and decreased with time, regardless of type of alpha-blocker. CONCLUSIONS: Use of alpha-blocker is associated with increased risk of hip fracture, especially in early use.

Uterine prolapse with pregnancy is rare condition. The overall incidence is 1/10000- 15000 deliveries. The complications from uterine prolapse range from minor cervical ulceration and infection to fetal death or uterine rupture. The fetal mortality was as high as 22% mainly due to prematurity, respiratory infection. The management of this condition is focused on preventing late occurrence of prolapse during pregnancy and continued reduction. We present a case of uterine prolapse in pregnancy with a brief review of the literature.

BACKGROUND: The purpose of our study was to evaluate the functional and radiologic outcomes of additive augmentation sutures through rotator cuff for proximal humeral fractures stabilized locking plate in elderly patients. METHODS: We enrolled 74 patients over the age of 60 years who received internal fixation using locking plates for proximal humeral fractures. Of these, 50 patients had additive augmentation sutures through rotator cuff. The mean age at the time of surgery was 72.1 years (range, 60-89 years), and the mean follow-up period was 17.5 months (range, 12-62 months). The humeral neck-shaft angle and humeral head height were used as radiological markers to assess the effect of additive augmentation sutures through rotator cuff. We allocated the patients who received additive augmentation sutures into group A and those who did not into group B. RESULTS: At the final follow-up, the mean Korean Showlder Society score and Constant scores were 88.96 +/- 12.1 and 86.6 +/- 11.9, respectively, in group A and 86.21 +/- 11.8 and 85.3 +/- 11.7, respectively, in group B (p=0.368, 0.271). At the final follow-up, the mean loss in humeral neck-shaft angle from the time of immediate postoperative measurement was 1.6degrees in group A and 4.8degrees in group B, whereas the mean loss in humeral head height was 0.82 mm in group A and 0.52 mm in group B (p=0.029, 0.178). CONCLUSIONS: The surgical outcomes of internal fixation using locking plates for proximal humeral fractures were clinically and radiologically good in elderly patients over the age of 60 years without any observable complications. Further, the loss of humeral head shaft angle at the final follow-up from its initial postoperative measurement was significantly smaller in patients who received an additive augmentation suture than in those who did not. Thus, we conclude that augmentation sutures are a beneficial option for elderly patients that clinicians can consider at the time of surgical decision making.

PURPOSE: The role of MRI in the detection of cholangiocarcinoma of the common hepatic duct has rarely been described. This study was attempted to ascertain characteristic MR features of cholangiocarcinoma. MATERIALS AND METHODS: The T1(500/30, TRs/TEs) and T2 weighted(200/80, TRs/TEs) MR images were obtained from nine patients with cholangiocarcinoma of the common hepatic duct. The common hepatic lesions were detected in seven cases. MR features of cholangiocarcinoma were analysed according to the signal intensity and associated findings. RESULTS: The seven cases showed lower signal intensity than the surrounding normal liver parenchyma on T1 weighted image. On T2 weighted image, the tumor showed isosignal intensity and hyperintensity in four and three patients, respectively. T2 image also revealed diffusely increased signal intensity in some hepatic lobe or segment in four cases, and Intrahepatic periductal high signal intensity in one case. Other associated MR findings were intrahepatic metastasis, and intratumoral hemorrhage, each noted in a different case. CONCLUSION: T2 weighted Image appears to be effective in the detection of cholangiocarcinoma of the common hepatic duct and evaluation of its associated intrahepatic lesions.
