ABSTRACT

Purpose@#Neoadjuvant chemoradiotherapy has been accepted as a standard treatment for stage II–III rectal cancer. This study aimed to evaluate the clinical characteristics of patients who underwent neoadjuvant chemoradiotherapy for rectal cancer and effects on overall survival (OS) of neoadjuvant chemoradiotherapy in South Korea. @*Methods@#Patients who underwent curative resection for rectal cancer from 2014 to 2016 were retrospectively reviewed from the database of the National Quality Assessment program in South Korea. Patients were categorized into the upfront surgery group and neoadjuvant chemoradiotherapy group. We evaluated factors associated with the administration of neoadjuvant chemoradiotherapy and its effects on OS. Inverse probability of treatment weighting was performed to account for baseline differences between subgroups. @*Results@#A total of 6,141 patients were categorized into the upfront surgery group (n = 4,237) and neoadjuvant chemoradiotherapy group (n = 1,904). The neoadjuvant chemoradiotherapy was more frequently administered to male, midrectal cancer, and younger patients. In the neoadjuvant chemoradiotherapy group, old age, underweight, and pathologic stage were significant risk factors of OS, and male sex, the level of tumor and clinical stages were not associated with OS.After adjustment, the OS of the neoadjuvant chemoradiotherapy group followed the OS of the upfront surgery group of the same pathologic stage. @*Conclusion@#Male sex and the level of tumor were not related to the OS of rectal cancer patients with neoadjuvant chemoradiotherapy. The OS of patients who underwent neoadjuvant chemoradiotherapy was decided by their pathologic stages regardless of clinical stages.

ABSTRACT

PURPOSE: Tuberculosis (TB) is one of the most important diseases that cause significant mortality and morbidity in young children. Data on TB transmission from an infected child are limited. Herein, we report a case of disseminated TB in a child and conducted a contact investigation among exposed individuals. METHODS: A 4-year-old child without Bacille Calmette-Guérin vaccination was diagnosed as having culture-proven disseminated TB. The child initially presented with symptoms of inflammatory bowel disease, and nosocomial and kindergarten exposures were reported. The exposed individuals to the index case were divided into 3 groups, namely household, nosocomial, or kindergarten contacts. Evaluation was performed following the Korean guidelines for TB. Kindergarten contacts were further divided into close or casual contacts. Chest radiography and tuberculin skin test or interferon-gamma-releasing assay were performed for the contacts. RESULTS: We examined 327 individuals (3 household, 10 nosocomial, and 314 kindergarten contacts), of whom 18 (5.5%), the brother of the index patient, and 17 kindergarten children were diagnosed as having latent TB infection (LTBI). LTBI diagnosis was more frequent in the children who had close kindergarten contact with the index case (17.1% vs. 4.4%, P=0.007). None of the cases had active TB. CONCLUSION: This is the first reported case of TB transmission among young children from a pediatric patient with disseminated TB in Korea. TB should be emphasized as a possible cause of chronic diarrhea and failure to thrive in children. A national TB control policy has been actively applied to identify Korean children with LTBI.

ABSTRACT

PURPOSE: Partially absorbable mesh has been introduced and used for inguinal hernia repair for the purpose of minimizing pain and improving abdominal wall compliance. In this study, we evaluate the efficacy and safety of ProFlex mesh, a partially absorbed mesh with new structural architecture. METHODS: We retrospectively reviewed 64 cases of totally extraperitoneal herniorrhapy (TEP) from January 2013 to December 2014 for their clinical features, including operation time, pain, postoperative complications, and recurrence. RESULTS: There were no significant differences in operation time, hospital stay, postoperative pain, or complications between the 28 patients who received the ProFlex mesh and the 36 who received nonabsorbable lightweight mesh, although one patient who received the nonabsorbable had a recurrence during follow-up. There were differences in operation time, complications, and hospital stay according to the surgeon's previous operation volume. CONCLUSION: This study showed that there were significant differences in the fixation strength of different polypropylene meshes in combination with various fibrin glues. ProFlex, a partially absorbable mesh with new architecture, was feasible and safe in TEP.

ABSTRACT

Surgery is a demanding and stressful field in Korea. Occupational stress can adversely affect the quality of care, decrease job satisfaction, and potentially increase medical errors. The aim of this study was to investigate the occupational stress and career satisfaction of Korean surgeons. We have conducted an electronic survey of 621 Korean surgeons for the occupational stress. Sixty-five questions were used to assess practical and personal characteristics and occupational stress using the Korean occupational stress scale (KOSS). The mean KOSS score was 49.31, which was higher than the average of Korean occupational stress (45.86) or that of other specialized professions (46.03). Young age, female gender, long working hours, and frequent night duties were significantly related to the higher KOSS score. Having spouse, having hobby and regular exercise decreased the KOSS score. Multiple linear regression analysis showed that long working hours and regular exercise were the independent factors associated with the KOSS score. Less than 50% of surgeons answered that they would become a surgeon again. Most surgeons (82.5%) did not want to recommend their child follow their career. Korean Surgeons have high occupational stress and low level of career satisfaction.

ABSTRACT

PURPOSE: Surgeons serve one of the most challenging and stressful professions. Ineffective control of occupational stress leads to burnout of the surgeon. The aim of this study was to obtain preliminary data on the sources and the degree of stress of surgeons and to determine the feasibility of the survey. METHODS: A total of 63 surgeons in our three affiliated hospitals were enrolled in this study. Fifty-five questions were used to assess the demographics, characteristics and Korean occupational stress scale (KOSS), which were prepared and validated by the National Study for Development and Standardization of Occupational Stress. RESULTS: Forty-seven of the 63 surgeons participated in this study (74.6%). The mean KOSS score of the survey was 50.9 +/- 8.55, which was significantly higher than that of other professions (P < 0.01). Drinking and smoking habits were not related to the KOSS score. Doing exercise was related to a low KOSS score in terms of low KOSS total score (P < 0.01). Average duty hours (P < 0.01) and night duty days per week (P = 0.01) were strongly related to higher KOSS in the linear regression analysis. CONCLUSION: This is the first study to evaluate job stress of surgeons in Korea. This study showed that Korean Surgeons had higher occupational stress than other Korean professions. A larger study based on this pilot study will help generate objective data for occupational stress of Korean Surgeons by performing a survey of the members of the Korean Surgical Society.

ABSTRACT

PURPOSE: The ErbB family is associated with cell growth, differentiation, cell survival, apoptosis, cell cycle progression, angiogenesis. In this study, the expressions of ErbB family of colorectal cancer specimen were investigated to determined correlations between the clinicopathologic characteristics and the expression of ErbB family in the curative resection for colorectal cancers, including cancer specific survival. METHODS: Patients who underwent the curative surgery for colorectal cancers from January 1997 to December 2000 at Ansan Medical Center, Korea University College of Medicine were enrolled in this study, and one hundred ninety six of colorectal cancer. The clinical relationship between the expression of ErbB family for colon adenocarcinoma and clinicopathologic characteristic factors including survival were analyzed. RESULTS: There was no clinical relationship of the expression of ErbB family with clinicopatholologic characteristics. However, survival analysis demonstrated that 5 year survival rates (5YSR) of patients with the positive expression of ErbB1 (EGFR) was lower than those of the negative expression of ErbB1 (P<0.05) in colorectal cancer patients. Moreover 5YSR of the positive expression of ErbB1 was lower than that of negative expression of ErbB1 in well differentiation subgroup, node negative subgroup, node positive subgroup, and also stage T3 subgroup (P<0.05). CONCLUSIONS: The positive ErbB1 expression of colorectal cancer was one of poor prognostic factors in patients with colorectal cancer in this study. We need the further study to prove the real relation between target therapy for the positive expression of ErbB1 (EGFR) in colorectal cancer and the improvement of survival rate.
