OBJECTIVE: To evaluate the efficacy of low dose gonadotropin releasing hormone agonist(GnRH-a) therapy combined with high dose human menopausal gonadotrpin(hMG) following estrogen & progesteron therapy for poor responders. METHODS: From May 1997 to Feb 1999, 36 patients who were defined as poor responders on previous consecutive two and more superovulation cycles were randomly allocated to lowdose GnRH-a short protocol with high dose hMG protocol pretreated with estrogen & progesterone(E/P therapy)(n=16)(study group) and the clomiphene citrate with hMG(n=20)(control group). All patients were planned to undergone in-vitro- fertilization(IVF) and embryo transfer(ET) after controlled ovarian hyperstimulation(COH). RESULTS: Two groups were similar with respect to clinical features and basal FSH and E2 levels. The mean level of E2 on day 5, 304.3+/-148.ng/ml in study group was significantly higher than that in control group, 182+/-34.9ng/ml. The mean levels of E2 on hCG day was also significantly higher in study group than control group(1324+/-320ng/ml, vs 414+/-168ng/ml). The mean day of hCG day in study group, 12.3+/-0.3 was shorter than that in control group, 13.8+/-0.4. The concellation rates of cycles were significantly lower in study group than control group(13.2% vs 84.2%). But clinical pregnancy rates did not showed the significant difference between two groups. CONCLUSION: The study suggested that a lowdose GnRH-a short protocol with high dose hMG pretreated with estrogen & progesterone can improve the ovarian response in poor responder group.

PURPOSE: To evaluate the embolic effect and pathologic change in the kidney after infusion of 50% acetic acidin the renal artery. MATERIALS AND METHODS: Five kidneys were embolized with 50% acetic acid mixed with saline(group A) and five were embolized with 50% acetic acid mixed with contrast medium (group B). Four rabbits(2 fromgroup A and 2 from group B) were sacrificed during the first day and the remaining six, 28 days afterembolization. To determine the effect of embolization and pathologic findings, the two groups were compared. RESULTS: Complete occlusion of the renal artery was observed in both groups; histologic findings indicatingtubular necrosis and blood clots within the renal artery were noted one day after embolization. After four weeks,complete necrosis of the renal arterial wall and tubular cells had occurred. The procedures required forembolization were easier in group B because the extent of embolization could be controlled by fluoroscopy. CONCLUSION: At 50% dilution after mixing with contrast medium, the embolie effect of acetic acid isperfect;because the embolic material is visualised the procedure was easier to control than embolization withalcohol. acetic acid can, threrfore, be used as an effective embolic agent in renal artery embolization.

One of the biggest change in the history of the Journal of Korean Neurosurgical Society(JKNS) had been introduced in 2005. From January 2005, all manuscripts submitted to JKNS should be written in English. This new regulation was followed by many changes in characteristics of the papers published on JKNS in 2005. The authors present an analysis of papers published on JKNS and compared with those of 2004 and 2003. In total, 184 articles were published in 2005. Since a review article was requested by the editorial office to the authors, 183 articles were peer reviewed. Eighty five clinical articles, 75 case reports, 19 laboratory investigations, two special articles and two technical reports were printed. This distribution was not statistically different from 2004's distribution (p=0.67), even though the ratio of clinical articles was decreased to 46.4% from 54.4%. Due to the change in language specification, English articles were increased with statistical significance (p<0.001). There were several events related with copyright of the contents of the papers published on JKNS. We think these are some good points came with change in official language to English. General trends of the papers seemed to be in the right way.

Two patients with cutaneous leishmaniasis were treated with itraconazole. One patient was a 24-year-old man who had several erythematous papulonodules on the extremities for 1 month, which revealed cutaneous leishmaniasis, histopathologically. He was treated with itraconazole (200 mg/day) for 2 months. After treatment he showed clinical healing and the biopsy specimens no longer showed leishmania organisms. The other patient was a 27-year-old female who had several erythematous papulonodules on the face and neck for 3 months. The skin lesions revealed leishmania organisms in the tissue sections and culture media. She was also treated with itraconazole (200 mg/day) for 2 months. After treatment she also showed satisfying clinical healing and the biopsy specimens revealed no leishmania organisms. No specific side effects were encountered in both patients during the treatment. From these results, itraconazole is considered to be one of the promising anti-leishmanial drugs.

PURPOSE: The purpose of this study was to develop a scale to assess the transition shock experienced by newly graduated nurses, and test the validity and reliability of the scale. METHODS: The initial items were identified through a review of literature and in-depth interviews with nine newly graduated nurses. Content validation of the items was evaluated by five nurse professors and three nurses. Participants were 269 newly graduated nurses who worked at six acute care hospitals in Busan, Ulsan, and Yangsan, South Korea. Data were analyzed using item analysis, exploratory and confirmatory factor analysis, criterion related validity, and internal consistency. RESULTS: The final scale consisted of 18 items and six factors (conflict between theory and practice, overwhelming workload, loss of social support, shrinking relationship with co-workers, confusion in professional nursing values, and incongruity in work and personal life), which explained 71.3% of the total variance. The six subscale model was validated by confirmatory factor analysis. Cronbach's alpha for the total items was. 89. Convergent validity was evaluated by analyzing total correlation with burnout (r=.71, p<.001) and turnover intention (t=5.84, p<.001). CONCLUSION: This scale can be used in the development of nursing interventions to reduce the transition shock experienced by newly graduated nurses.

This study was performed to observe the effectiveness of thymectomy in the management of myasthenia gravis. Twenty-seven myasthenic patients were undergone thymectomy at Keimyung University Dongsan Hospital between January 1981 and December 1990. The most prevalent age group was the 3rd decade and the myasthenic syrnptom developed below thirty in most. Seven patients had remission and 10 patients fared better after thymectomy. There was no significant effect with age and duration of the disease in the result of thymectomy. Those with less severe group had better response than more severe group and non-thymoma group had higher remission rate without statistical significance than thymoma group. There were better response and more complications in the group with maximal thymectomy than simple thymectomy. This study demonstrated that the effect of thymectomy was better in less severe, nontymoma and maximal thymectomy group in myasthenia gravis.

OBJECTIVE: The authors present a retrospective analysis of the long-term recurrence rate for the 79 craniopharyngima patients surgically treated between Jan 1989 and Dec 1999. METHODS:Tumor recurrence rates were analysed with respect to age of patients, symptom duration, tumor size, localization of tumor, morphology of tumor, the extent of surgical resection, pathologic diagnosis and the other treatment modalities. RESULTS: For 79 patients, with a mean follow-up period of 5 years, the overall recurrence rate was 29%. Factors associated with decreased risk of recurrence was gross total tumor resection(p=0.01). Subtotal resection was associated with increased risk of tumor recurrence. The adjuvant radiation therapy was revealed efficient not in decreasing recurrence rate but in the delay of tumor recurrence time(p=0.05). There were no differences in recurrence rates for other factors. CONCLUSION: A rigorous evaluation of recurrence for craniopharyngima must consider the extent of resection, as judged by postoperative imaging. Adjuvant radiation therapy or Gamma knife surgery could be the effective treatment modalities.

Telomere shortening has been suggested as an indicator of aging and psychiatric disorders. However, few studies have explored the relationship between telomere length (TL) and irritable bowel syndrome (IBS). We investigated the association between TL and IBS in 43 IBS patients using quantitative polymerase chain reaction. The clinical characteristics and severity of IBS, assessed by the visual analogue scale, were also analyzed. The average TL was 4.40 ± 3.87, with TL shortening tending to be associated with female sex and smoking. However, these associations did not reach statistical significance. Correlation analysis showed a negative correlation between IBS severity and TL (r = –0.285, p = 0.083), although this was not statistically significant. No other clinical characteristics were significantly associated with TL. This is the first study to examine the relationship between TL and IBS. Our findings suggest that TL may have potential as a predictor for IBS diagnosis.
