BACKGROUND: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described for Neer type II fracture, the optimal treatment remains controversial. This study reports the clinical results and usefulness of anatomical locking plate with additional K-wire fixation. METHODS: A totally of 21 patients with type II distal clavicle fracture were included in the study. The surgical procedure reduced the fracture temporarily; it included insertion of one or two K-wire from the lateral margin of the distal fragment to the proximal fragment through the fracture site, followed by application and fixation of the locking plate. The bony union and migration of K-wire was evaluated in the follow-up radiography. The coracoclavicular distance and acromioclavicular joint arthrosis were assessed at the final follow-up. The Constant Score (CS) and Korean Shoulder Score (KSS) were evaluated for clinical scoring. RESULTS: Bone union was achieved in all cases. At the final follow-up, coracoclavicular distance of the injured shoulder was increased, as compared to the intact shoulder (p=0.002), with no accompanying clinical symptoms. No K-wire migration was observed. At the final follow-up, K-wire irritation was observed in two cases and acromioclavicular arthrosis in one case, with no other adverse effects. Pain visual analogue scale, CS, and KSS were improved in all cases. CONCLUSIONS: The method of anatomical locking plate with additional K-wire fixation could be useful in achieving beneficial clinical results.

The rim sign in renovascular compromise may be defined as a thin nephrographic rim outlinning a kidney with another wise faint nephrogram. Renal infarction with gelform and blood clots was induced experimentally in 5 dogsand high dose IVP and CT were performed to evaluate renal cortical rim sign after renal infarction. One expireddue to anesthetic technical failure, and one was embolized partially. So we could be obtain the result on 3 dogs.The reults were as follows; 1. The high dose IVP films show cortical rim sign on 24 hrs and 72 hrs films in twodogs. The CT films show rim sign in 3 dogs. 2. The rim sign may be visualized, if the renal artery is occuludedenough to drop perfusion presssure below the authoregulatory range. 3. The high dose IVP and early nephrogramphase are necessary for the rim sign.

BACKGROUND AND OBJECTIVES: The goal of this study was to examine the safety and feasibility of a primary (direct) stenting in acute myocardial infarction (AMI). In the treatment of AMI, Percutaneous transluminal coronary angioplasty (PTCA) has documented superior reperfusion rate and improved clinical outcomes than thrombolytic therapy. However, there are several limitations of PTCA, such as recurrent ischemia in 10 to 15%, reinfarction in 3 to 5% and restenosis in 30 to 50% of patients. There are several reports that, compared with PTCA, the implantation of coronary stent has been shown to reduce angiographic restenosis and improve late clinical outcomes. But in general, stenting has been contraindicated in thrombus containing lesion due to the risk of subacute thrombosis. With advance in technique and the recognition of the importance of adequate platelet inhibition, the incidence of subacute thrombosis has fallen in patients with acute coronary syndrome and thrombus laden lesion. Methods and Results: In our study, primary stenting was performed in 42 patients of AMI. There are 6 cases (22.5%) target lesion restenosis during the follow up coronary angiography (150+/-86day) and no in-hospital death. Three cases (7.1%) of them require revascularization including two re-PCTA and a coronary artery bypass graft for the recurrent ischemic symptoms. There were no reinfarction and death after discharge. Six-months event free survival reate was 85.7%. CONCLUSION: Primary stenting is safe and feasible in the majority of patients with AMI and results in excellent mid-term outcomes compared with PTCA.

PURPOSE: To determine the clinical efficacy of SS-cream, the topical agent made from the extracts of natural products for treating premature ejaculation(PE), a double blind, randomized placebo controlled phase III study on the patients with primary PE was performed in three medical centers. MATERIALS AND METHODS: Mean age of patient with primary PE was 38.7+/-0.6 years and duration of suffer from PE was 15.8+/-0.4 years. We investigated the ejaculatory latency calculated by stop watch and sexual satisfaction rate after the treatment(1 placebo and 5 SS-cream 0.2gm). Patients were instructed to apply the cream on the glans penis 1 hour before sexual intercourse in double blind randomized fashion. Clinical efficacy was compared with the prolongation of ejaculatory latency and improvement of sexual satisfaction rate. RESULTS: 106 patients with primary premature ejaculation completed this study. Mean ejaculatory latency tested at screening period was 1.37+/-0.1 min and both of patient and partner were not satisfied with their sexual lives. The mean ejaculatory latency was significantly prolonged as 10.92+/-1.0 min with SS-cream, while 2.45+/-0.3 min with placebo. In 79.8%, there was prolongation of ejaculatory latency longer than 2 minutes with SS-cream, while in 15.1% with placebo. The sexual satisfaction rate was also significantly improved as 82.2% with SS-cream, while 12.6% with placebo. 103 (16.2%) out of 636 trials of SS-cream showed mild local irritation including 82 mild burning senses and 21 mild pain, which disappeared in less than 1 hour. No adverse effect on sexual function and partner and no systemic side effects were observed. CONCLUSIONS: With these results, SS-cream is effective and safe in the treatment PE with mild local side effect.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.

PURPOSE: The purpose of this study is to find helpful MR findings for predicting a naplastic oligodendrogl lomas. MATERIALS AND METHODS: Retrospective analysis of 46 MR images and 37 CT scans was performed for 46 patients with pathologically-proven cerebral oligodendrogliomas. A neuropathologist graded the tumors as one of low-grade (n=16), intermediate-grade (n=l2), or anaplastic oligodendroglioma (n=18). MR imaging features were retrospectively analysed with respect to histologic grading of the tumors. RESULTS: Contrast enhancement was observed always in anaplastic group (17 /17), in a portion of intermediate-grade group (4/10) but not in low-grade group (0/14). Peritumoral edema was observed infrequently in anaplastic group (4/18) or intermediate-grade group (1/12). Cystic changes (25/46) or calcifications on CT Scans (14/37) were not related with histologic grading. Grossly identifiable hemorrhage was rare in this series (2/46). Among the various imaging features, only tumor enhancement and peritumoral edema were statistically significant for trend test (p<0.05). CONCLUSION: When considering the diagnosis of oligodendrogliomas, the presence of contrast enhancement or peritumoral edema is a helpful features suggesting anaplastic oligodendrogliomas.

In order to evaluate the long-term effect of single lateral rectus muscle recession for the moderate angle exotropia(20-3-PD), we retrospectively studied 30 cases which were recessed by 8-9mm. The average follow-up period was 35.8 month. At 6 month postoperatively, the success rate was 75% in 8mm recession group and 84% in 8.5mm group, 88% in 9mm group. At the last follow-up, the success rate was 62%, 38%, 22% respectively. The recession of single lareral rectus muscle for the moderate angle exotropia was successful during the early postoperative period. But, its success rate was gradually decreased in the long-term follow-up especially for exotropia over 25PD. So, we should consider to recess lateral rectus muscle more than 8-9mm or choose the classic surgical method such as both lateral rectus recession or recession-resection for exotropia over 25PD.
