Oral allergy syndrome (OAS) is an IgE-mediated allergy caused by cross-reacting antigenic determinants in pollens and various fruits, vegetables, and nuts which are known as the most common food allergy in adults. Cross-reactive antigenic proteins include pathogenesis-related-10 protein, profilin, cross-reactive carbohydrate determinant and lipid transfer protein. The prevalence of OAS has been reported at up to 70% of birch pollen allergy. A nationwide multicenter study in our country has recently reported that the prevalence of OAS in Korea is 41.7% of pollen allergy. Typical symptoms of OAS are tingling, itching sense and edema of lips, mouth, and throat immediately after ingestion of raw fruits, vegetables, or nuts. These can progress to systemic symptoms including anaphylaxis. The diagnosis can be made by typical clinical history in patients with pollen allergy. Skin prick test using fresh fruits extracts can be helpful in confirming sensitization to foods, which has better sensitivity than commercial skin prick test or serum specific IgE test. Treatment of OAS is to avoid causative foods. Self-injectable epinephrine should be considered in the case of anaphylaxis. Allergen-specific immunotherapy to pollens has also been tried.

The related factors of the quality of life (QOL) in stroke patients was identified empirically. The subjects were 254 stroke patients who were discharged and taken follow-up care at the outpatient department. In this model, the physical, psychological, and social status were assumed to affect the QOL. And the social support was assumed to moderate these effects. NIH stroke state, ADL, and IADL were used to measure the physical status. Using CES-D, the psychological status was measured. The social status was defined as the job change after stroke attack. The satisfaction with the care by primary caregivers, significant others, and health professionals was measured as the social support. To identify the effect of the physical, psychological, and social status on the QOL, multiple regression analysis was carried out. The psychological and social status were found to be the significant predictors of the QOL(R2=0.27, p=0.00). Next, to identify the moderating effect of the social support, the subjects were divided into two groups, that is, the low social support group and the high social support group. It is found that the predicting variance is different between these two groups. In the low social support group, the psychological, social, and physical status predicted as much as 42% of the QOL. On the contrary, the psychological status predicted only 8% of the QOL in the high social support group. So it is concluded that the social support moderates the effects of the physical, psychological, and social status on QOL. Finally, to identify the social support which moderates those effects, the social support was divided into three classes. Each social support class was divided into the low and high social support group again. In the every class of social support, the difference between two groups was also identified. So the model of the QOL is recommended for the framework of the care for the stroke patients. Also these results support the claim that the long-term facilities for stroke patients are necessary.

The quality of life associated with eating is becoming an increasingly significant problemfor patients who undergo esophagectomy as a result of the improved survival rate afteresophageal cancer surgery. Delayed gastric emptying (DGE) is a common complication afteresophagectomy. Although several strategies have been proposed for the managementand prevention of DGE, no clear consensus exists. The purpose of this review is to presenta brief overview of DGE and to help clinicians choose the most appropriate treatmentthrough an analysis of DGE by cause. Furthermore, we would like to suggest some tips toprevent DGE based on our experience.

Objective: Minimizing residual tumors is one of the most important prognostic factors in the management of advanced ovarian cancer [1]. In ovarian cancer patients with cardiophrenic lymph node (LN) metastases, transabdominal cardiophrenic lymph node dissection (CPLND) has been performed along with the surgery on the primary site [2]. However, CPLND for the complicated locations in the thoracic cavity is still technically challenging. This video aims to share our surgical technique for the transabdominal CPLND. Methods: A 60-year-old woman who presented with suspicious bilateral ovarian cancer was hospitalized for cytoreductive surgery. Preoperative CT demonstrated peritoneal seeding and multiple LN metastases including right anterior, lateral, posterior, and left anterior cardiophrenic LNs. The gynecology and general surgery team underwent hysterectomy, bilateral salpingo-oophorectomy, supracolic omentectomy, lower anterior resection, right diaphragmatic and bladder peritonectomy, pelvic and paraaortic LN dissection, and appendectomy. The thoracic surgeon took over the operation because the pelvic cavity was regarded as R0. CPLND was performed by transabdominal, subxiphoid approach. The procedure is narrated in the video. Results: Complete clearance of CPLN leaving no gross residual disease was possible without complication. A long, transverse incision of the anterior diaphragm was closed with a 1-0 polypropylene in the way of double layered continuous running suture and 8 times ties for the final knot. Conclusion Transabdominal CPLND can be used safely and effectively without change of patient's position and with minimal diaphragmatic injury. However, this approach may be unfeasible for metastatic internal mammary LN dissection and still needs meticulous surgical skills to avoid complications.

PURPOSE : Since the year 2000, lung cancer has been the leading cause of cancer death in South Korea and also in many other parts of the world. MATERIALS AND METHODS : We developed a multidisciplinary (MD) care system for lung cancer patients in 1996. Here, we report the results obtained in the process of development of MD team (MDT). RESULTS : The MDT was launched with including medical doctors, chest surgeons, radiation oncologists, radiologists, nuclear medicine specialists and physician assistants. To facilitate co-operation between the MDT members, a specialized out-patient clinic was located within a sector of the hospital. A common ward was allocated for lung cancer patients regardless of the department of the attending physician. Shared electronic medical record forms that were specialized for lung cancer were developed. The MDT operates weekly lung cancer conferences and multidisciplinary out-patient clinics. To make diagnostic or therapeutic decisions early on, the electronic medical records of the patients were previewed or consulted by the specialists before they meet the individual patients. CONCLUSION : Despite every effort, we still need to shorten the waiting time from presentation to the first treatment and we need to improve the patients' satisfaction. We also have a mission to develop our own regulations and guidelines for our lung cancer MD care system. Clinical trials and basic research should also be encouraged along with improving the quality of life of the team members

BACKGROUND/AIMS: The treatment outcome of patients hospitalized in intensive care units (ICUs) can be influenced by physician factors, including both intensivists and resident physicians. We evaluated the association between the number of residents who are exclusively responsible for the ICU and the mortality rate in a medical ICU. METHODS: The data obtained from an open medical ICU in a teaching hospital from Jan. 2005 to Dec. 2009 were analyzed retrospectively. We evaluated the associations between the ICU mortality rate and both the number of resident physicians and the number of patient-days per resident physician using multivariate Poisson regression analysis adjusted for year and month. RESULTS: The months with fewer than two residents tended to have a higher ICU mortality rate, although this difference was not significant in the univariate analyses. Multivariate Poisson regression analysis showed that months with fewer than two residents had a significantly higher ICU mortality rate compared with months with two residents (incidence risk ratio (IRR) 1.59, 95% confidence interval (CI) 1.05-2.41; p=0.029). The number of ICU patient-days per resident physician was not associated with the ICU mortality rate (IRR; 1.00, 95% CI, 0.99-1.01; p=0.649). CONCLUSIONS: The presence of fewer than two residents exclusively responsible for the medical ICU was an independent risk factor of a higher ICU mortality rate. However, no association was found between the number of ICU patient-days per resident physician and the ICU mortality rate.

Tracheobronchomalacia is developed by excessively weakened walls of the trachea and bronchi, and shows dynamic collapse of the airway on expiration and causes dyspnea. Airway stenting or surgical correction of the airway may be helpful. We report a case with tracheobronchomalacia which was combined with chronic empyema and treated successfully with stent insertion.

PURPOSE: Lung cancer has been the leading cause of death in South Korea since the year 2000. Adenocarcinoma became the most frequent type in the national survey of lung cancer since year 2005. MATERIALS AND METHODS: We analyzed 5,456 cases with lung cancer from 2004 to 2012 in a community cancer center. The mean age was 69.9 years, and 78.9% was male. RESULTS: Adenocarcinoma (ADC, 40.8%) was the most frequent type, followed by squamous cell carcinoma (SQC, 36.4%), small cell carcinoma (SCC, 14.8%) and non-small cell lung cancer (NSCLC) not otherwise specified (8.1%). In male patients, SQC was the most frequent type (43.5%), while ADC showed highest incidence in females (72.6%). Anatomic stage at diagnosis in NSCLC was I (10.3%), II (5.8%), IIIA (15.7%), IIIB (19.2%), and IV (49.0%). In SCC, 41.7% was in limited stage and 58.3% was diagnosed in extensive stage. The proportion of never smoker has been increased from 19.1% in 2004~2008 to 25.4% in 2009~2012. Never-smokers are more likely to be female (68.2% vs. 4.0%, p<0.001), have ADC (69.9% vs. 31.3%, p<0.001), and manifest as stage IV disease (58.5% vs. 45.2%, p<0.001), compared to smokers. Among 1,908 cases whose initial treatment was recorded, 42.5% received chemotherapy, 25.7% received radiation treatment, 20.5% received surgery and the remaining 11.3% received supportive cares only or transferred to other health care facilities. CONCLUSION: In conclusion, proportion of lung cancer in never-smoker is increasing. As screening for smokers will miss this growing population, we need to discover biomarkers to find high risk population of lung cancer.
