Pulmonary Alveolar Hemorrhage after Clopidogrel Use for ST Elevation Myocardial Infarction
김영중,Joohan Lim,Jonggu Lim,SOO-HYUN KIM,Tae Young Jung,Woong-Gil Choi 대한심장학회 2013 Korean Circulation Journal Vol.43 No.7
Combination treatment of antiplatelet drugs containing aspirin and clopidogrel reduces systemic ischemic events after percutaneous coronary intervention (PCI) in high risk patients. However, this combination treatment of antiplatelet drugs is associated with increased risk of nonfatal and fatal bleeding. Diffuse alveolar hemorrhage after PCI is a rare complication that has been mostly reported in associa-tion with glycoprotein IIb/IIIa inhibitors. We report the case of a 62-year-old man who presented with ST elevation myocardial infarction and suffered a diffuse alveolar hemorrhage after clopidogrel use following primary PCI.

Purpose: We evaluated men with documented chronic prostatitis and elevated serum prostate-specific antigen (PSA) to determine whether treatment with antibiotics and anti-inflammatory drugs can lower serum PSA and the cancer detection rate in patients with post-treatment PSA <4 ng/ml. Materials and Methods: Eighty-six men who presented with serum PSA greater than 4 ng/ml and who were subsequently diagnosed with chronic prostatitis with greater than 10 white blood cells per high power field in expressed prostatic excretions were included in this prospective study. Patients meeting these criteria underwent treatment with a 4-week course of antibiotics and nonsteroidal anti-inflammatory agents. Follow-up PSA and transrectal ultrasonography-guided prostate biopsy were performed within 2 months of treatment for all patients. Results: Mean patient age was 56.2 years (range, 37-72 years). Mean PSA (ng/ml) decreased by 33.8%, from 8.12 (range, 4.02-24.8) to 5.37 (range, 1.35-12.94), after treatment (p=0.001). Pathological studies revealed prostate cancer in 18 cases (20.9%), chronic inflammation in 64 (74.4%), and benign prostatic hypertrophy in 4 (4.7%). The prostate cancer detection rate according to the follow-up PSA level, below 2.5, from 2.5 to 4.0, and above 4.0, was 13.3% (2/15), 13.6% (3/22), and 26.5% (13/49), respectively. Conclusions: When chronic prostatitis with elevated PSA is identified, antibiotic and anti-inflammatory treatment can lower these PSA levels. However, the possibility of prostate cancer remains in patients whose PSA level decreases to less than 4 ng/ml, even in those with a PSA level less than 2.5 ng/ml.

Purpose: The aims of this study were to investigate the clinical significance of transrectal ultrasonography (TRUS) and the efficacy of dutasteride (5α-reductase inhibitor) in patients with hemospermia. Materials and Methods: From January 2005 to December 2008, 60 patients with hemospermia were enrolled in the study. All patients underwent a digital rectal examination and TRUS; serum prostate specific antigen was also measured. The management of hemospermia was one of the following: watchful waiting, dutasteride treatment, or antibiotics with dutasteride. Results: Thirty-four patients (56.7%) had positive findings on TRUS. There were 16 cases (26.7%) of prostate calcification, 13 cases (21.7%) of ejaculatory duct cyst, 3 cases (5%) of ejaculatory duct calcification, a case of seminal vesicle inflammation, and a case of ejaculatory duct dilation. Dutasteride treatment resulted in improvement of symptoms in 87.9% (29/33) of the cases, whereas treatment with antibiotics or antibiotics with dutasteride resulted in a 100% (6/6) success rate. However, among 14 watchful waiting patients, only 3 patients (21.4%) showed an improvement of symptoms. Conclusions: This study showed that TRUS is an easy and effective method for the assessment of hemospermia, and also revealed that dutasteride could be a useful agent in the treatment of hemospermia.
156폐쇄성 수면무호흡질환에서 구개근 절제술과 구개근 및 보존적 구개수 절제술의 술 후 결과 비교

Background and Objectives:Palatal muscle resection (PMR) is a surgical method that treats retropalatal airwayobstruction. Sometimes elongated uvula can aggravate obstructive symptom in obstructive sleep apnea (OSA)patients. Uvulectomy is usually done in such cases to resolve the obstructive effect of the uvula. The purpose ofthis study was to compare postopreative results of PMR and PMR with partial uvulectomy in treating obstructivesleep apnea (OSA). Materials and Methods:Thirty-three patients with OSA due to retropalatal obstruction weretreated with surgical method from June 2011 to May 2013. Seventeen patients underwent PMR and 16 patientsunderwent PMR with partial uvulectomy. Surgical method was decided by preoperative drug induced sleep en-doscopy (DISE) analysis. Postoperative satisfaction criteria were analyzed before and after 3 months of each sur-gery via questionnaires based on visual analogue scale (VAS) of snoring, sleep apnea, and daytime sleepiness. Post-operative complications were analyzed before the surgery as well as 1, 4, and 12 weeks after the surgery viaquestionnaires based on VAS about foreign body sensation, dry throat, velopharyngeal insufficiency, swallowingdifficulty, and voice change. Results:Postoperative satisfactions were significantly (p<0.05) improved in bothgroups. There was no significant (p>0.05) difference in postoperative satisfactions between the two groups. For-eign body sensation and dry throat were significantly (p<0.05) increased in PMR with partial uvulectomy group. But these complications were resolved within 3 months. Conclusions:The PMR with partial uvulectomy grouphad more complications than the PMR group. Our results suggested that PMR with partial uvulectomy was pref-erable for cases requiring uvulectomy because some complications were resolved spontaneously
The driving forces of collective action among policy actors: Value, power, and social capital
김영중,노철영 한국행정학회 2015 International Review of Public Administration Vol.20 No.3
This study explores the core factors for the policy actors to select their policy partners in the policy processes, focusing on the mechanism underpinning the communication density between policy actors in the networks. For the purpose, this study identifies three major candidate groups: policy actors’ values, policy actors’ power, and social capital between policy actors. Then, with the relational data collected by the survey on the Korean international migration policy processes, we try to find core factors affecting communication density between policy actors. The results show that the most influential factors are found in the group of social capital while the variables around policy actors’ value systems are shown to be statistically insignificant, and that what is more important is not the trust based on receiver’s social reputation but the instant trust created during the policy process. This research also indicates that formal voting power is one of the significant variables in deciding the communication density between policy actors.

The seismic qualification for the class 1E battery of Korea Multipurpose Research Reactor was accomplished by the analysis as well as testing. The full rack consists of 4 similar sections of typical frame structure and contains 60 cells. However, since the seismic qualification was required on the frame structure and only on 3 aged ones among 60 dells, 2 sections of the full rack were assembled as a test rack with 28 cells including the 3 aged cells for an economic test. Seismic analysis for the full rack was carried out using the finite element program ANSYS. The modal parameters identified from the resonance search thest on the test rack were used to the seismic analysis of the full rack. It was confirmed that the test rack could represent the full rack with regards to seismic responses and function of cells, and that the full rack and aged cells were qualified to the given seismic test requirements.
