BACKGROUND: Although warts are known to be caused by viruses, one of their peculiarities is that they may be treated by suggestion therspy or hypnosis. This suggests that psychologic or emotional factors influence the hosts response to the virus lesions. OBJECTIVE: The purpose of the study was to analyze the role of psychologic factors in the therapeutic response of warts. METHODS: The self-concept scale test(Korean Testing Center) was done in all 61 patients with common wsrts before the cryot.herapy from September 1991 to June 1993. Clinical follow-up data were obtained on 50 patients after 2 months, and then were evaluated usir g the self-eoncept scale in treated vs untreated group. RESULTS: 1. The overall cure rate was 56.0%, being higher in females and patients with high education, 1-3 in number of lesions and no previous treatment history as well as in those with less than 1 year of duration. 2. In the comparison of self-concept scale between treated(n=18) and untreated(n=22) groups, the treated group had remarksble results in moral ethical self, personal self and family self scores (p<0.05). Only 14 items were significantly different between two groups(p<0.05 by Wilcoxon rank sum test). 3. Patients of 20 years or more showed a high cure rate(67.79%, p<0.05 by t-test) and demonstrated significance in total positive self score and its self identity, and satisfaction, self behavior, physical self, moral ethical self and family self scores(p<0.05, by t-test). CONCLUSION: The self-cancept significantly related to the positive aersonality, harmonious family, stable self-esteem and high normal ethics, may influence at least the therapy to the warts in the treated patients in contradistintion to the untreated ones.

Hemifacial spasm consists of irregular, but repetitive clonic twitching of the muscles of one side of the face. Usually it is first involved around the eyes, the repetitive twitching spreads slowly to involve the whole face. It most commonly affects middle aged or elderly women, and usually appears with an aberrant vascular cross-compression near the root entry zone (REZ) of VII nerve. Among numerous approaches to treat facial spasm, only Jannetta's microvascular decompression has confirmed efficacy. However facial nerve block by needle insertion technique seems to be of benefit in patients with mild spasm, the elderly, poor risks and those who refuse the craniotomy. To treat our three patients with hemifacial spasm, we did physical facial nerve block by a direct puncture of the facial nerve trunk just at its exit from the stylomastoid foramen. Satisfactory results were obtained by the treatment employed. This technique is a valuable method in the treatment of hemifacial spasm.

PURPOSE: Thallous-201 chloride produced at Korea Cancer Center Hospital(KCCH) is used in detecting cardiovascular disease and cancer. Thallium impurity can cause emesis, catharsis and nausea, so the presence of thallium and other metal impurities should be determined. According to USP and KP, their amounts must be less than 2 ppm in thallium and 5 ppm in total. In this study, the detection method of trace amounts of metal impurities in [201Tl]TlCl injection with polarography was optimized without environmental contamination. MATERALS AND METHODS: For the detection of metal impurities, Osteryoung Square Wave Stripping Voltammetry method was used in Bio-Analytical System (BAS) 50W polarograph. The voltammetry was composed of Dropping Mercury Electrode (DME) as a working electrode, Ag/AgCl as a reference electrode and Pt wire as a counter electrode. Square wave stripping method, which makes use of formation and deformation of amalgam, was adopted to determine the metal impurities, and pH 7 phosphate buffer was used as supporting electrolyte. RESULTS: T1, Cu and Pb in thallous-201 chloride solution were detected by scanning from 300 mV to -800 mV. Calibration curves were made by using TlNO3, CuSO4 and Pb(NO3)2 as standard solutions. Tl was confirmed at -450 mV peak potential and Cu at -50 mV. Less than 2 ppm of Tl and Cu was detected and Pb was not detected in KCCH-produced thallous-201 chloride injection. CONCLUSION: Detection limit of thallium and copper is approximately 50 ppb with this method. As a result of this experiment, thallium and other metal impurities in thallous-201 chloride injection, produced at Korea Cancer Center Hospital, are in the regulation of USP and KP. Polarograph could be applied for the determination of metal impurities in the quality control of radiopharmaceuticals conveniently without environmental contamination.

Between 1977 and 1987, 20 patients with mesothelioma were treated at Severance Hospital. Data was gathered from medical charts at the time of hospitalization of mesothelioma patients and from a follow-up questionnaire by mail or telephone. The results acquired were as follows: 1. Among the 20 patients, 11 men and 9 women with mesothelioma were identified. The mean age at hospitalization was 47 years and 11 mesothelioma patients were known or presumed to be dead during the different observation periods. 2. Only one mesothelioma patient had a definite history of occupational asbestos exposure. 3. The sites of orgin of mesothelioma were the pleura(13), peritoneum(2), pericardium(2), mediastinum(2), and pelvis(1). Common symptoms included dyspnea, chest pain, abdominal distension, etc. 4. Pathologically, mesotheliomas were divided into 14 malignant types and 6 benign types ; and histologically, 8 fibrous mesotheliomas and 3 epithelial mesotheliomas were shown. 5. There was a statistically significant difference in survival rate according to pathologic type and smoking status. In the groups with malignant mesothelioma, 50% survival time from first symptoms was 18 months and that from diagnosis was 11 months. Also, 75% survival time from diagnosis was 6 months in the smoking groups and 19 months in the non-smoking groups.

OBJECTIVES: To confirm the HAVS in workers exposed to hand-arm vibration with using the objective diagnostic methods METHODS: Several tests were used to help substantiate a clinical diagnosis of HAVS. Some other diseases were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was evaluated for considering HAVS. Peripheral vascular changes were examined by a cold provocation test. An electromyography was implemented to ascertain the peripheral neural changes. RESULTS: 8 workers with symptoms in hands & fingers, exposed to hand-arm vibration were examined. Some other diseases(primary Raynauds disease, secondary Raynauds disease in not occupational origin) were excluded by a medical interview, hematologic assessment, urinalysis, X-rays. The hand-arm vibration acceleration level of the grinder was 7. 9 m/sec2. The recovery time of a skin temperature followed finger cooling was significantly prolonged in 6 workers with HAVS. The nerve conduction velocity was reduced in 6 workers with HAVS. CONCLUSIONS: So we report 6 cases of HAVS in grinding workers exposed to hand-arm vibration diagnosed objectively by an exclusion of some other disease, handarm vibration acceleration level, cold provocation test, electromyography.

10.Clinical Efficacy of Glucagon Like Peptide-1 (GLP-1) Analogues.
Journal of Korean Diabetes 2013;14(3):125-127
Recently, incretin hormone-based therapies, including glucagon-like peptide-1 (GLP-1) analogues and dipeptidyl peptidase-4 (DPP-4) inhibitors, have become the main therapeutic tools in the hyperglycemia management in patients with type 2 diabetes mellitus. These therapeutic agents could fill an important gap in glycemic control for patients with type 2 diabetes because the incretin response is blunted in type 2 diabetes mellitus. GLP-1 analogues can be classified as exendin-4 backbone (Exenatide, Exenatide LAR and Lixisenatide) and human GLP-1 backbone (Liraglutide, Taspoglutide and Albiglutide). Among these, Exenatide, Exenatide LAR and Liraglutide are currently available. This review will focus on the clinical efficacies of GLP-1 analogues in glycemic control for patients with diabetes.
