Objective: This study is to investigate the clinical efficacy of low-dose FSH regimen, comparing with clomiphene citrate and human menopausal gonadotropin (CC/hMG) regimen. Methods: Retrospective study of the ovulatory factor infertility 39 patients who had been treated by intrauterine insemination (IUI). The 31 cycles of 21 patients were stimulated by CC/hMG regimen, the 22 cycles of 18 patients were stimulated by low-dose FSH regimen. We compared the rate of clinical pregnancy, multiple pregnancy and ovarian hyperstimulation syndrome (OHSS) of both group. Results: The rate of clinical pregnancy of the CC/hMG group was 25.7% per cycle, and that of the low-dose FSH group was 54.5% per cycle. The low-dose FSH group showed a higher rate of clinical pregnancy per cycle than CC/hMG group (p=0.028). However, no differences was found statistically in the rate of multiple pregnancy and OHSS between CC/hMG group (22.2%, 5.7%) and low-dose FSH group (33.3%, 13.6%). Conclusion: This study showed that the low-dose FSH regimen is superior to CC/hMG regimen in getting clinical pregnancy, but dose not reduce the ovulation induction complications.

Purpose: The aim of this study was to investigate effects of calcific lesion on shockwave therapy of the tennis elbow. Materials and Methods: twenty-four patients with refractory tennis elbow were treated with shock waves. The patients were evaluated by assessment of pain using visual analog scale (VAS) and simple elbow test (SET). Comparision of clinical outcomes for the patients with and without calcification in the extensor tendon and/or cortical irregularity of lateral condyle was tried to determine if this could be a possible prognostic factor in clinical settings. Overall clinical outcomes were evaluated by Roles and Maudsley score at 12 months after ESWT. Results: Significant improvement of symptoms were observed in 20 (83 %) patients at 12 months follow up according to Roles and Maudesley scores. The patients with calcification and/or cortical irregularity improved significantly better, when compared to the patients without calcification and/or cortical irregularity at follow up. Conclusion: This study suggests that shock waves therapy could be considered as effective and noninvasive treatment modality for refractory tennis elbow. Also calcific deposit in extensor tendon and/or cortical irregularity of the lateral epicondyle was seem to be good prognostic factor for shock wave therapy for tennis elbow

Objective : Brain-derived neurotrophic factor (BDNF) is implicated in the pathophysiology of several neuropsychiatric disorders. However, there are few studies on BDNF of panic disorder. In this study, we investigated plasma BDNF levels in patients with panic disorder, and evaluated whether there are associations between clinical characteristics of panic disorder and plasma BDNF levels. Methods : We included 110 patients with panic disorder and 110 health controls in the current study. Plasma BDNF levels were measured by the enzyme-linked immunosorbent assay (ELISA). Plasma BDNF level differences were evaluated according to the clinical characteristics, such as duration of illness, recent stressful life event, agoraphobia, and insomnia. Results : The mean plasma BDNF levels of patients with panic disorder were significantly lower, as compared with those of controls (192.50 pg/mL vs. 693.75 pg/mL, t=8.838, p<0.001). The mean plasma BDNF levels of patients who had recent stressful life events were significantly higher, as compared with those who did not ($269.79{\pm}358.96pg/mL$ vs. $136.94{\pm}187.06pg/mL$, t=-2.525, p=0.013). Conclusion : These results suggested that BDNF plays a potential role in the pathophysiology of panic disorder.

Thymoma is defined as a neoplasm of the epithelialreticular framework cells of the thymus. The treatment of choice and the prognosis for patients with thymoma are still controversial subjects due to lack of a uniform histological classification and standardized criteria for typing thymic tumors. Between June 1985 and May 1989, eight patients underwent thymomectomy at the Department of Thoracic and Cardiovascular Surgery, Korea University Medical Center. A clinical analysis was performed and the following result was obtained. In histologic cell type, epithelial type was 2 cases, lymphocytic type 3 cases, and mixed type was 3 cases. The clinical stage was classified by Masaoka’s classification that Stage I was 4 cases, Stage II; 2 cases, Stage III; 2 cases and Stage IV was none. Myasthenia Gravis was associated with thymoma in 5 patients. In 8 patients, thymomectomy were performed. Adjuvant radiotherapy was performed in one patient with Stage I due to suspicious tumor remnant and in Stage II, III patients routinely. Combined chemotherapy was performed in one patient with Stage III due to local recurrence. We concluded that the most important prognostic factor of thymoma is extent of tumor invasion. And the presence of Myasthenia Gravis is no more prognostic factor. Surgical resection of thymoma is treatment of choice, If local invasion or distant dissemination is present, postoperative radiotherapy and /or combined chemotherapy is recommended.

Background: Mutations affecting the epidermal growth factor receptor (EGFR) are good predictors of clinical efficacy of EGFR tyrosine kinase inhibitors (TKI) in patients with non-small cell lung cancer. Serum carcinoembryonic antigen (CEA) levels are also regarded as predictive for the efficacy of EGFR-TKI and EGFR gene mutations. This study analyzed the association between EGFR gene mutations and clinical features, including serum tumor marker levels in lung adenocarcinomas patients. Patients and Methods: A total of 70 lung adenocarcinoma patients with complete clinical data and pathological specimens were investigated. EGFR gene mutations at exons 19 and 21 were assessed. Serum tumor markers were detected by protein chip-chemiluminescence at the corresponding time, and correlations were analyzed. Results: Mutations of the EGFR gene were detected in 27 of the 70 patients and the serum CEA and CA242 concentrations were found to be significantly associated with the incidence of EGFR gene mutations (P<0.05). The AUCs for CEA and CA242 were 0.724 (95% CI: 0.598~0.850, P<0.05) and 0.769 (95% CI: 0.523~0.800, P<0.05) respectively. Conclusions: Serum CEA and CA242 levels are associated with mutations of the EGFR gene in patients with lung adenocarcinomas.

Purpose: This study was to identify the factors that influence the burnout of clinical nurses. Methods: Subjects were 279 nurses in 3 university hospitals at Seoul and Gyunggi province. Data were collected with self-administered questionnaires and analyzed using SPSS 16.0 by applying t-test, ANOVA, Pearson correlation, and Stepwise multiple regression. Result: There are significant differences between burnout and demographic characteristics, such as, age, marital status, education level, clinical career, and position. All variables except emotional labor were negatively correlated with burnout. The emotional labor was positively correlated with burnout. Job satisfaction, emotional labor, self-efficacy, and age had significant influence on nurses' burnout. The explained variances for burnout was 54.8% and job satisfaction was the most significant factor of burnout of nurses. Conclusion: Emotional labor is found to be a new factor that influences burnout. Therefore, it is necessary to establish new organizational culture through emotional education programs at the organizational level to reduce nurses' emotional labor.
