Recently, the bcl-2 and p53 protein have been recognized as important factors that is contributed to programmed cell death. The objective of this study was to evaluate the prognostic significance of bcl-2 and p53 protein expression in uterine cervical carcinoma. The expression of bcl-2 and p53 in 59 cases of uterine cervical carcinoma (stage IB to IIB) were surgically treated from January 1993 to June 1994. The expression of bcl-2 and p53 was examined by immunohistochemical method using formalin fixed paraffin embedded tissue specimens. The 48 cases were squamous cell carcinoma and 11 cases were adenocarcinoma. The results were as follows: 1. The expression rate of bcl-2 protein was 28.8%(17/59) and there was no significant correlaltion between the expression of bcl-2 protein and the clinicopathologic parameters (histologic type, grade, FIGO stage, cervical invasion depth, lymph node metastasis, parametrial invasion, tumor size, neoadjuvant chemotherapy response, recurrence, survival). 2. The expression rate of p53 protein was 32.2%(19/59) and there was no significant correlation between expression of p53 protein and the clinicopathologic parameters. 3. There was significant correlation between and expression of bcl-2 and p53 protein (P 0.05). In conclusion, bcl-2 and p53 protein are thought to be possible factors in the carcinogenesis of uterine cervical carcinoma and correlate with progression of it. But further study will be required to clarify the role of bcl-2 and p53 in carcinogenesis of the uterine cervix.

PURPOSE: The 2005 guidelines for cardiopulmonary resuscitation (CPR) caution that effective compression is essential (Class I) and chest compression (CC) by rescuers should be switched every 2 minutes to avoid rescuer's fatigue. It is controversial how long effective CC by a single individual can be provided. There are few reports about CPR quality, especially when rescuers perform CC for more than 10 minutes. The mean CPR period was about 30 minutes in Korea. We investigated the quality of CC and rescuer's fatigue after about 30 minutes. METHODS: From April 2009 to July 2009, health care providers (HCPs) were recruited into this study. The study simulated 2 person, in-hospital CPR. On the test day, which had been randomly assigned, each participant performed 7 CCs for about 30 minutes. The period of each CC was 2 minutes, and the period of each circulation check was 5 seconds. Participants' heart rates (HR) and visual analogue scale (VAS) scores for fatigue were obtained before and after each CC. Data for each 2 minutes CC was obtained with the use of Resusci Anne(R) with the Laerdal(R) PC skill reporting system. We used one-way repeated measures ANOVA for comparison of quality and fatigue of each CC and multiple linear regression for finding the predictors for correct CC. SPSS 17.0 was used for analysis. RESULTS: Among a total of 30 HCPs, data from 27 were analyzed. All participants were certified as a BLS provider and some were certified as BLS instructors. The rate of effective compression was 83.8+/-24.3%. Despite 2 min CC tasks were repeated alternatively for about 30 minutes, there were no differences in the number of correct CCs, depth and velocity of compression, and the number of incorrect CCs. CONCLUSION: During in-hospital CPR, HCPs may provide effective chest compressions on shifts with minimal effect of fatigue, even if they provide CC for 30 minutes.

OBJECTIVE: The purpose of this study was to review the clinicopathologic features, recurrent rate, survival rate and controversable issues in the treatment of the ovarian malignant germ cell tumors. PATIENTS AND METHODS: From August, 1991 to November, 1998 thirty-one patients with malignant germ cell tumors of the ovary treated in the department of obstetrics and gynecology, Kosin University Medical college, were eligible and assessable. Demographic characteristics, symptoms, signs, stage, tumor grade, mode of therapy and results of follow up were reviewed retrospectively. RESULTS: The patients with malignant germ cell tumor constituted 6.37% of all ovarian malignancies during this period. Histologic subtypes were 8 dysgerminoma(25.8%), 7 endodermal sinus tumor(22.6%), 10 immature teratoma(32.3%), 3 mixed germ cell tumor(9.7%), 3 choriocarcinoma(9.7%). The age of the patients ranged from 10 to 40 years (mean +/-S.D.; 24.26 +/- 7.51). The most common symptom was abdominal pain(38.7%). Most had stageI(18 cases, 58.0%) or stageIII(5 cases, 16.2%) diseases. All patients underwent surgery as the initial treatment, and nine patients received more than one operation. Postoperative adjuvant chemotherapeutic regimens were VAC, VBP, EP, BEP, EMA, and EMA CO. The mean follow up duration was 26.0(+/- S.D.; +/- 20.3) months. The 2-year and 5-year survival rate were 91.97%(+/- S.E.; +/- 0.05) and 86.86%(+/- S.E.; +/- 0.07).

Background and Objectives: The conjunctivodacryocystorhinostomy (CDCR) is rarely performed in epiphora, which is caused by complete proximal bicanalicular obstruction. The purpose of this study is to analyze the characteristics, clinical results and complications of patients who underwent CDCR.Subjects and Method We enrolled 12 patients who underwent CDCR due to proximal canalicular obstruction from 2006 to 2019. We retrospectively analyzed the causes of epiphora, trauma history, the cause of revision operation and the clinical outcome. Results: A total of 12 patients (7 males and 5 females) underwent CDCR (mean age 46 years). The causes of trauma were such as laceration (n=7, 58%) and iatrogenic (n=1, 8%), idiopathic obstruction (n=4, 33%). After the initial surgery, 5 patients (41%) were categorized in good outcome and the Jones tube was located well in 6 (50%) patients. Revision surgery was performed in 6 (50%) cases, with 4 cases having good outcome. The success rate of CDCR, including revision surgery, was increased to 83%. Most common cause of revision surgery was tube migration. In addition, the subjective outcome in patients with traumatic causes were worse but it had no statistical significance compared to that of patients with idiopathic and iatrogenic causes (p=0.07). Conclusion About a half of the patients had good recovery rate after the initial operation. The outcome increased to 83% after revision operation. The success rate of CDCR for traumatic patients was worse than for those with idiopathic and iatrogenic causes. It seems that accompanied eyelid damage in traumatic patients may have affected the result of success rate.

OBJECTIVE: The human MAGE 3 gene encodes tumor specific antigens that are recognized by autologue cytotoxic T lymphocytes (CTL). The MAGE 3 gene is expressed not only in melanoma but in the other malignant tumors as well. There is, however, little information on the expression of the gene in uterine cervical carcinomas. The author thus studied the expression of the MAGE 3 gene products in uterine cervical carcinoma and discuss the possibility of specific immunologic diagnosis using MAGE 3 gene products. METHODS: The expression of MAGE 3 gene product in 17 normal tissues of the cervix, 32 cervical intraepithelial neoplasia (8 CIN I, 10 CIN II, 14 CIS), and 43 invasive cervical carcinomas was studied by immunohistochemistry using anti-MAGE 3 mAb 57B in paraffin sections RESULTS: No expression of MAGE 3 gene product was detected in normal cervical tissues and in cervical intraepithelial neoplasias. The expression of MAGE 3 gene product was detected in 30.2% (13/43) of invasive cervical carcinomas. The MAGE 3 gene product was stained as a cytoplasmic protein in cancer cells. No statistically significant differences were observed between MAGE 3 gene product expression status and clinicopathologic parameters. CONCLUSIONS: The MAGE 3 gene products was expressed in invasive cervical carcinoma tissues.

OBJECTIVE: Mycoplasmas have been implicated in many diseases including cervicitis, urethritis, salpingitis, endometritis... and functioning as cofactors catalyzing the HIV disease state. The oncogenic potentiality of mycoplasma was only recently realized when they were shown causing chromosomal changes and in vitro cell transformations through gradual progressive chromsomal loss and translocation. Few study has been reported the prevalence of mycoplasma infection in human cancers and suggested that there was a connection between these organisms and human cancers. The objective of this study was to determine the relationship between Ureaplasma urealyticum infection and cervical cancer. METHODS: The detection frequency of Ureaplasma urealyticum in 52 invasive cervical cancer tissues and 17 normal cervical tissues was studied using PCR. RESULTS: U. urealyticum DNA was detected in 8 out of 52(15.4%) invasive cervical cancer tissues and 1 out of 17(5.9%) normal cervical tissues. No statistic significance was observed between the detection frequency of Ureaplasma urealyticum and clinicopathologic parameters. The prevalence of Ureaplasma urealyticum in invasive cervical tissues was 15.4% and this rate was higher than 5.9% in normal cervical tissues but there was no statistic significance. CONCLUSIONS: With respect to clinicopathologic parameters of cervical cancer, there was no significant relation between U. urealyticum infection and cervical cancer. There is, however, few study and case on cervical cancer internally and externally. It is considered that more studies on the subject with much cases should be made.

PURPOSE: The aim of this study was to evaluate the feasibility of monitoring external branch of the superior laryngeal nerve (EBSLN) during robotic thyroid surgery. METHODS: A total of 10 patients undergoing bilateral axillo-breast approach (BABA) robotic thyroid surgery were enrolled. The nerve integrity monitor (NIM Response 2.0 System) was used for EBSLN monitoring. We performed voice assessments preoperatively and at 1 and 3 months postoperatively using Voice Handicap Index-10 (VHI-10), maximal phonation time (MPT), phonation efficient index (PEI), and laryngeal electromyography (EMG). RESULTS: A total of 19 EBSLNs were at risk and 14 EBSLNs (73.7%) were identified using neuromonitoring. VHI-10 showed a change of voice over time (0.1 vs. 3.6 vs. 1.3); however, this was not statistically significant. VHI-10 scores normalized at 3 months postoperatively compared to the preoperative scores. MPT (a) (16.0 vs. 15.6 vs. 15.4), and MPT (e) (20.1 vs. 15.4 vs. 18.5) showed no significant differences preoperatively compared to the values obtained 1 and 3 months postoperatively. There was a significant change of PEI over time (4.8 vs. 1.1 vs. 4.6) (P = 0.036); however, the values normalized at 3 months postoperatively. Laryngeal EMG results showed 4 cases (21.2%) of neuropathy of EBSLNs at 1 month postoperatively, and electrodiagnostic studies revealed nearly complete recovery of the function of EBSLNs in 4 patients at 3 months postoperatively CONCLUSION: It is suggested that neuromonitoring of EBSLNs during BABA robotic thyroid surgery is feasible and might be helpful to preserve voice quality.

BACKGROUND: Effective chest compression may improve the return of spontaneous circulation and neurologic outcome in arrest victims. For fear of rescuer's fatigue, guidelines for cardiopulmonary resuscitation (CPR) recommended that chest compression (CC) should be switched every 2 minutes, but there is little evidence. We investigated whether health personnel could provide consistent quality of CC for 2 minutes. METHODS: We recruited prospectively health personnel working on one university hospital. On the day assigned randomly, CPR performance data was collected with use of CPR recording technology. Quality of CPR was calculated every 30 seconds interval. To identify the quality decay, we used repeated measure analysis of variance with SPSS 17.0 for analysis. RESULTS: We analyzed 8,485 CCs performed by 41 subjects. Total number of CC decayed between 90 to 120 seconds (51.6 +/- 3.3 to 50.8 +/- 3.5, p = 0.020) within recommended range. The ratio of correct depth CC decayed between 90 to 120 seconds, falling from 83.4 +/- 24.9% to 68.3 +/- 38.4% (p = 0.002). The ratio of low depth CC increased significantly over time (10.2 +/- 20.7% to 31.3 +/- 38.5%, p < 0.001). CONCLUSIONS: Health personnel may provide adequate number of CC for 2 minutes. But, the number of correct depth CC may decay between 90 to 120 seconds. Also the number of low depth CC may increase over time.
