Differential independent lung ventilation is gaining growing attention for management of patients with unilateral pulmonary pathology. This case presents the method for the intraoperative anesthetic management of a patient with empyema and bronchopleural fistula of the left lung which could be controlled by the use of dual-mode asynchronous lung ventilation. The healthy right lung was ventilated by a conventional mechanical ventilator and disessde left lung by a high frequency jet ventilator. The use of endotracheal anesthesia and high frequency ventilation were necessary to prevent drainage of infected secretions into the right side healthy lung and to achieve good gas exchange in the presence of a bronchoplsural fistula. The method used by us, high frequency ventilation for the diseased lung a conventional mechanical ventilation for the other, demonstrated that differential independent lung ventilation using double lumen tube as in this case was suited for handling the problem of a bronchopleural fistula and empyema, further extending the indication for a giant lung bulls, lung cyst, major tracheobronchial disruption and one lung contaminating the other lung with either infected material or blood.

We reported a case of huge cystic trigeminal neurinoma. The patient was 35 year old female with trigeminal nerve dysfunction and hemiparesis. The computed tomography disclosed a huge cystic low density mass at the temporal base and suprasellar cistern that extended to cerebellopontine cistern through the tentorium, and enlargement of Meckel's cave on coronal scan. Through the infratemporal and retromastoid suboccipital approach, the cystic content was aspirated and cyst wall was removed. The cystic change of neurinoma may be due to mucoid degeneration and liquifaction.

When difficulties occur during anesthesia and the management of intensive care patients, there may not be sufficient time for frequent, accurate and detailed recordings which are essential for medico-legal purposes and the retrieval of information. However, it is during such occasions that the collection of an accurate, detailed record may be nearly impossible. A system, bases on the 16bits microcomputer linked to a Datascope 2000, has been developed to collect cardiovascular data on line from a cardiovascular monitor. The computer can be operated by using the main anesthetic record program written in a C language which enables the interrupt facility in the microcomputer and interface card to detect and store data transmitted from the Datascope. Patient's details are entered by manipulating function keys on the keybord. All information is stored on a disc for subsequent analysis. A formed graph and text can be displayed on the screen. The graph and all the information entered can be printed out at the end of the operation to form a complete anesthetic record.

Radiofrequency ablation (RFA) is a well-known, effective, and safe method for treating benign thyroid nodules and recurrent thyroid cancers. Thyroid-dedicated devices and basic techniques for thyroid RFA were introduced by the Korean Society of Thyroid Radiology (KSThR) in 2012. Thyroid RFA has now been adopted worldwide, with subsequent advances in devices and techniques. To optimize the treatment efficacy and patient safety, understanding the basic and advanced RFA techniques and selecting the optimal treatment strategy are critical. The goal of this review is to therefore provide updates and analysis of current devices and advanced techniques for RFA treatment of benign thyroid nodules and recurrent thyroid cancers.

PURPOSE: The urinary mass screening program for the detection of proteinuria had been performed for a school age population in the city of Seoul since 1981. However, systematic evaluation for this program had never been done. We, therefore, designed a systematic evaluation in corporation with the Seoul School Health Center for students with proteinuria identified in the mass screening to determine the prevalence of asymptomatic proteinuria, and to estimate the risk of incipient renal diseases and incidences of some of them. And also, we attempted to reveal the significance of urinary mass screening. METHODS: In the period of 8 years betwen 1987 and 1994, annually about a half million students, who comprised 3 different age groups, 5th grade of elementary school, 2nd grade of junior school and 2nd grade of high school were chosen, corresponding to the approximate ages of 11, 14 and 17 years, respectively. These subjects accounted for 25% of total school children in Seoul. The screening program was carried out in 3 steps. The 1st test was performed at schools and the 2nd at the School Health Center. Those students who showed proteinuria in the 1st and 2nd tests were referred to the hospital. Laboratory examinations including renal biopsies were performed in those students with pathologic proteinuria to clarify the incipient renal diseases. RESULTS: 1) The prevalences of asymptomatic proteinuria were 0.2-0.36% (average 0.28%) in the 1st test. It peaked at the age of 14 years 0.36%, compared to 0.2% in the 11 age group and 0.25% in the 17 age group. 2) There was a difference of asymptomatic proteinuria by sex and age, higher prevalence in the female in the 11 age group but higher in the male in the 17 age group. 3) The distribution of proteinuria in accordance with various types classified by us at the 3rd test showed as follows: transient proteinuria (type 1) 17%, orthostatic proteinuria (type 2) 55%, constant proteinuria (type 3) 6%, proteinuria with hematuria (type 4) 20%, isolated proteinuria (type 5) 2%. Pathologic proteinuria comprised of type 3, 4 and 5, accounted for 28%, which was 1/10 of proteinuria in the 1st test. 4) The annual incidence of renal glomerular diseases among the age goup of 7-18 years was estimated to be 2.8 per 10,000. 5) Renal pathologic studies on 80 children with proteinuria and hematuria (66) or constant proteinuria (14) revealed IgA Nephropathy (38.9%) was the most frequent glomerular diease. MPGN 10.0%, MGN 7.5%, Reflux Nephropathy 7.5%, FSGS 6.2% were followed, respectively. HBV asssociated Nephropathy was 7.5%. 6) 4 of Reflux Nephropathy and 2 of FSGS were found in the 14 children with constant proteinuria in the screening test. Among these children, 5 progressed to chronic renal failure. 7) The annual incidence of IgA Nephropathy among the age group of 7-18 years was 1.1 per 10,000. 8) The morbidity of chronic renal failure was estimated to be 9.8 per 1 million of 7 to 18 years age group. CONCLUSIONS: 1) Most Students, approximately 90%, who were found to have asymptomatic proteinuria in the initial screening were normal so clinical evaluations for them should be very much cautious. Only 10% of them had pathologic proteinuria which denoted incipient renal diseases. 2) Annual incidences of incipient renal glomerular diseases, IgA Nephropathy and chronic renal failure were estimated to be 2.8 per 10,000, 1.1 per 10,000 and 9.8 per 1 million among school children in Seoul. 3) Because of the high incidence of significant glomerular changes and the high rate of progression to chronic renal failure in children with constant proteinuria, it should be regarded as serious one. 4) The definite conclusion that a urinary mass screening program can alter the prognosis of children with renal diseases identified in the mass screening can not be drawn with this study. Further study must be necessary.

Background and purpose: Environmental factors might influence the pathogenesis of Parkinson's disease (PD) or multiple-system atrophy (MSA), and previous examinations of pesticide exposure, well-water drinking, and farming have produced inconclusive results. Because agriculture has been of considerable importance to Korean society, and hence the risk of exposure to pesticides was high in Korea, this study investigated whether such exposure is associated with elevated risks of developing PD and MSA. Methods: Two hundred and thirty-five PD patients, 133 MSA patients, and 77 normal control subjects were examined. Data concerning environmental factors were collected by face-to-face interviews using a structured questionnaire. Odds ratios (ORs) were calculated by binary logistic regression. Results: ORs for environmental risk factors for developing PD were 1.06 [95% confidence interval (CI) = 1.02-1.10] for age and 2.37 (95% CI = 1.32-4.27) for rural well-water drinking for >10 years. Smoking >10 pack-years (OR = 0.31; 95% CI = 0.11-0.64) was a preventable factor for developing PD in this study. However, no significant risk factors were identified for MSA. Conclusions: These results suggest that exposure to certain environmental risk factors plays a role in the development of PD. However, the development of MSA appears to be independent of environmental risk factors in Korean patients.

OBJECTIVES: To correlate Frey's syndrome with subjective symptoms, Minor's starch iodine test results, and infrared thermography measurements, and to discuss the utility of thermography as a quantitative diagnostic method. METHODS: This study included 59 patients who underwent unilateral parotidectomy. A subjective clinical questionnaire and an objective Minor's starch iodine test were performed to evaluate the incidence of Frey's syndrome. Infrared thermography was performed, and the subjects were divided into seven groups according to the temperature differences between operated and unoperated sites. The thermal differences were correlated with the results from Minor's starch iodine test and the subjective symptoms questionnaire. RESULTS: Of the 59 patients, 20 patients (33.9%) reported subjective symptoms after eating; 30 patients (50.8%) tested positive for Minor's starch iodine test, 19 patients (63.3%) of which reported subjective symptoms. Of the 29 patients who were negative for the iodine test, 2 patients (6.9%) reported subjective symptoms. Thus, subjective symptoms were well correlated with Minor's starch iodine test (r=0.589, P<0.001). As the thermal differences with infrared thermography increased, the number of patients with subjective symptoms increased (chi2=22.5, P<0.001). Using infrared thermography, the mean temperature difference in the positive group for the iodine test was 0.82degrees C+/-0.26degrees C, and that in the negative group was 0.10degrees C+/-0.47degrees C. With increased thermal differences, more patients showed positivity in the iodine test (chi2=29.9, P<0.001). CONCLUSION: Subjective symptoms, Minor's starch iodine test, and infrared thermography are well correlated with one another. Quantitative thermography provides clues for the wide variation in the incidence of Frey's syndrome, and could be a useful method for diagnosing and studying Frey's syndrome.

PURPOSE: Although Pokeweed intoxication is relatively less severe, thereis little data onthe clinical presentation ofPokeweed intoxication in Korea. This study examined the clinical aspectsto providebasic data for evaluating Pokeweed intoxication. METHODS: A retrospective study by a chart review was performedon 19 patients who ingested Pokeweed and presented to anacademic emergency department with an annual census of 40,000 between March 2012 and May 2012. RESULTS: Nineteen patients were identified. All patients wereintoxicated unintentionally. The most common symptoms were vomiting with diarrhea and abdominal pain. The onset time varied, but occurs 30 minutes to 5 hours post ingestion of Pokeweed. All patients were discharged without fatal complications. CONCLUSION: Compared to previous reports, mostpokeweed poisoning patients complain of gastrointestinal symptoms. Supportive care is the mainstay of the management of pokeweed intoxication. All symptoms were resolved over a 24 to 48 hour period.

PURPOSE: The optimal treatment strategy for locally advanced pancreatic cancer (LAPC), particularly the role of concurrent chemoradiotherapy (CCRT), remains debatable. We compared the clinical outcomes of CCRT and palliative chemotherapy alone (CA) in patients with unresectable LAPC. MATERIALS AND METHODS: Patients with LAPC who were consecutively treated between 2003 and 2010 were included. Resectability was evaluated according to National Comprehensive Cancer Network ver. 1.2012. The clinical outcomes for each treatment group (CCRT vs. CA) were evaluated retrospectively. RESULTS: Sixty-three patients (58.9%) and 44 patients (41.1%) were treated with CCRT and CA, respectively. The CCRT cohort included patients who were treated with CCRT with or without chemotherapy backbone (CCRT alone, induction chemotherapy-CCRT, CCRT-maintenance chemotherapy, and induction-CCRT-maintenance chemotherapy). Median progression-free survival (PFS) and overall survival (OS) of all patients were 7.2 months and 13.1 months. PFS of the CCRT and CA groups was 9.0 months and 4.4 months, respectively (p=0.020). OS of the CCRT and CA groups was 15.4 months and 9.3 months, respectively (p=0.011). In multivariate analysis, the adjusted hazard ratio of CCRT was 0.536 (p=0.003) for OS and 0.667 (p=0.078) for PFS. Although the pattern of failure was similar in the CCRT and CA groups, the times to both local and distant failure were significantly longer in the CCRT group. CONCLUSION: In patients with unresectable LAPC, those who underwent CCRT during their entire treatment courses had longer OS than patients treated with chemotherapy alone.
