Vocal fold injections are usually performed with a patient wake in an office under local anesthesia. For comfortable and safe office-based procedures, thorough anesthesia and premedication should be provided to the following three regions; nasal cavity, oropharynx, and larynx. Topical lidocaine is most widely used anesthetics on office based procedure. Lidocaine has a low to intermediate potency, 45 minutes to 60 minutes' duration of action, and onset of sufficient anesthesia within 90 seconds of topical administration. Tetracaine, prilocaine, ropivacaine, and bupivacaine also have been used in the office-based procedures. Nasal decongestant, oxymetazoline, is also used for widening nasal cavity by constriction of nasal mucosa. The amount of topical and local anesthetics used in vocal fold injection rarely exceeds toxic doses. The physician should know proper anesthesia techniques and must be familiar with the safe dose and complication of all anesthetics used.

Objectives : The purpose of this study was to examine cognitive and psychological characteristics of patients with military service suitability issues compared to the general psychiatric outpatients. Methods : 108 patients who visited psychiatric clinic center due to military service suitability issues and 80 general psychiatric patients were recruited from the Department of Psychiatry of university hospital. ANCOVA and chi-equare test were used to examine differences between two groups. Furthermore, we utilized paired t-test to compare the scrore within military group depending on when they performed the psychological assessment. Results : There were no significant differences between military group and general outpatient group in WAIS-IV scores. However, military group scored remarkably higher than control group on validity scales, F-r and Fp-r whereas they scored lower on validity scale, K-r. Furthermore, military group showed significantly higher on BDI and MMPI-2-RF, EID, RCd, RC2, RC3, COG, HLP, SFD, NFC, STW, SAVE, SHY, DSF, NEGE-r, INTR-r. As a result of comparison within the military group following the periods of assessment, military group did not show the significant differences on the overall scales of MMPI-2-RF. Conclusions : The present study showed that military group tends to report their psychological distress more exaggeratedly. In addition, they had significantly elevated not only emotional distress such as depression and anxiety but interpersonal problem. The implications and limitations were discussed along with some suggestions for the future studies.

Surgical angioplasty of isolated stenosis of the left main coronary artery(LMCA) restores a more physiologic flow to the myocardium, allows percutdneous transluminal coronary angioplasty (PTCA) of distal coronary stenoses at a later stage, and is a less time consuming and convenient procedure than the conventional coronary artery bypass grafting(CABG) . Between Jul. 1994 and Dec. 1995, 7 surgical angioplasty had been performed. LMCA stenoses involved ostium in 2 patients, middle third in 3, and dis- tal third in 2. In 2 patients, the origin of left anterior descending coronary artery was involved in conjunction with LMCA. T e additional coronary artery stenoses were found in 2 cases. One patient was emergently operated after coronary angiography following his cardiac arrest. LMCA was approached anteriorly in all patients. The pulmonary artery was transected in 3 patients for a better exposure. The onlay patch consisted or autologous or bovine pericardium. There was no postoperative myocardial infarction or mortality. Left ventricular functions were well preserved in all patients. Postoperative coronary angiography revealed widely patent LMCA in 5 cases, and mild narrowing of distal anastomotic sites in 2 cases. Provided that well defined indications are followed correctly, surgical angioplasty can be a safe alternative to conventional CABG.

Purpose : Ttransfusion transmitted virus(TTV) is a circular DNA and consists of diverse genotypes and variants. The pathogenecity of TTV is still unclear. Recently another circular single stranded DNA virus, distantly related to TTV was isolated from the sera of blood donors, designated as Transfusion transmitted virus like minivirus(TLMV). TTV and TLMV show greater sequence divergence from each other than between genotypes of TTV. We planned to know the prevalence of TLMV in children. Methods : TLMV DNA was detected by PCR primers from noncoding region of the genome in 88 children without hepatitis, aged 0~15 years. PCR products derived from 10 children were directly sequenced and phylogenetic analysis was undertaken. Results : TLMV DNA was detected in 49% of 88 children without hepatitis. The prevalence of TLMV varied with age : <1 y, 16%(4/25); 1~3 y, 62%(18/29); 4~6 y, 43%(7/16); 7~9 y. 16%(1/6); 10~15 y, 66%(8/12). Mixed infection with TTV was confirmed in 22% of 88 children. Pyhlogenetic analysis of 10 TLMV sequences showed much heterogeneity compared to sequences of GenBank. Conclusion : TLMV prevalence in children was 49% in Korean children. Our TLMV sequence did not cluster in any sequence of TLMV in the GenBank.

The patient was a 30-day-old female infant with symptoms of severe dyspnea and cyanosis, when she was admitted to the ER. The echocardiography revealed DORV with subpulmonary VSD, and the diagnosis of Taussig-Bing anomaly was made. Two days after admission, an urgent operation was performed. The operation consisted of intraventricular tunnel repair and arterial switch operation. She was discharged, and after checking her chest X-ray through OPD, there was no interval change of cardiomegaly. She was then re-admitted, and the angiography revealed coactation of aorta. We performed a resection and end-to-end anastomosis of aorta. She is currently in good condition 11 months postoperatively.

This research is to figure out the influence of hand holding and Nea-Guan acupressure to anxiety and pain that local anesthesia patients feel in out patient operation room. Non equivalent control group pretest-posttest time series design was adopted and the data had been collected from Jul. to Oct. 2013. Total 78 local anesthesia patients of out patient operation room in the H Hospital were allotted by control group, experimental group 1( hand holding) and experimental group 2(Nea-Guan acupressure) which consisted of 26 patients each. Hand holding and Nea-Guan acupressure in this research was validated to relieve the anxiety and the pain of the local anesthesia patients in operation and can be adopted as an efficacious nursing interventions.

A 55-year-old male was admitted to our hospital complaining of chest discomfort, dysphagia and severe pain on swallowing. Esophageal manometry showed that there was no relaxation of lower esophageal sphincter to swallowing. There was double barrelled esophagus or mucosal stripe appearance on esophagogram. Endoscopy revealed an appearance as if an esophago-tracheal fistula had been made at the level of the upper thoracic esophagus. Also, two slit-like mucosal tears was seen on the lower esophagus. There after, fasting and total parenteral nutrition for several weeks failed to bring about any changes in his symptoms. So, as treatment, primary closure of the upper opening of the false lummen was performed under general anesthesia. Soon after the surgical procedure, the patient's symptoms were improved except for mild dysphagia. He was discharged after oral intake had been juduciously commenced with fluids and soft diet subsequently. During follow-up in out-patient department, he had no specific symptoms including fever or dysphagia and massive dissection of the esophagus was improved on esophagogram. We report the experience of a case of spontaneous submucosal dissection of the esophagus which required conservative and surgical management

Imperforated hymen, vaginal atresia or high transverse vaginal septum are caused by incomplete vaginal canalization. The infant may be present with distention of the vagina and the uterus with glandular secretions stimulated by maternal estrogens, known as hydrometrocolpos. We report two cases of hydrometrocolpos. In the first case, distal vaginal atresia with cystovaginal fistula was revealed by a contrast fluoroscope through the percutaneous catheterization. In the second case, urogenital sinus was detected by a fistulogram through a single orifice in the genital area. We decompressed the cystic mass by ultrasonogram guided aspiration, promptly at birth, then achieved the transient drainage of cystic fluids by percutaneous catheterization.

Thymoma is the most common tumor in the compartment of anterior mediastinum. The malignant thymoma is classified into invasive thymoma(category I) and thymic carcinoma(category II). Recently, well-differentiated thymic carcinoma is a proposed category 1.5 used to describe a subset of thymic epithelial tumors, allowing for the existence of intermediate form based on the clinical features and the histological characteristics. Thymic cyst is a congenital or a acquired disorder. Congenital thymic cyst may develop due to failure of the thymopharyngeal duct to obliterate and acquired thymic cyst develops from inflammation(multilocular thymic cyst), or neoplasm(cystic thymoma). Cystic degeneration in thymoma is a relatively frequent but focal event. In rare cases, the process proceeds to the extent that most or all of the lesion becomes cystic. Until now, well-differentiated thymic carcinoma with extensive cystic degeneration has not been reported in our country. We experienced a case of 14 year-old female patient showing extensive cystic degeneration in well-differentiated thymic carcinoma. And so we report it with review of the articles related.

The purpose of this study was to identify the incidence of neutropenia in patients with breast cancer who received chemotherapy and to identify the differences in incidence according to influential factors. We analyzed the medical records of 353 breast cancer patients who received chemotherapy at university hospital in Seoul, Korea from January 2010 to March 2016. The collected data were analyzed by descriptive statistics, $X^2-test$, and logistic regression analysis using SPSS 20.0. Among the 353 subjects, 33.1% had neutropenia, and the factors that showed significant difference according to neutropenia were exercise performance, RT status, and regimen. The results of this study suggest that it is important to predict the prevalence of neutropenia in breast cancer patients receiving chemotherapy and to provide appropriate education and nursing intervention.
