PURPOSE: The association between liver enzymes and death from external causes has not been examined. We investigated the association between serum aminotransferase levels and external-cause mortality in a large prospective cohort study. MATERIALS AND METHODS: A total of 142322 subjects of 35-59 years of age who completed baseline examinations in 1990 and 1992 were enrolled. Mortalities were identified using death certificates. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were categorized into quintiles. Sub-distribution hazards ratios and 95% confidence intervals (CIs) were estimated using a competing risks regression model in which deaths from other causes were treated as competing risks. RESULTS: Of 8808 deaths, 1111 (12.6%) were due to external causes. Injury accounted for 256 deaths, and suicide accounted for 255. After adjusting for covariates, elevated ALT and AST were significantly associated with an increased risk of all external-cause mortalities, as well as suicide and injury. Sub-distribution hazards ratios (95% CIs) of the highest versus the lowest quintiles of serum ALT and AST were, respectively, 1.57 (1.26-1.95) and 1.45 (1.20-1.76) for all external causes, 2.73 (1.68-4.46) and 1.75 (1.15-2.66) for suicide, and 1.79 (1.10-2.90) and 1.85 (1.21-2.82) for injury. The risk of external-cause mortality was also significantly higher in the fourth quintile of ALT (21.6-27.5 IU/L) than in its first quintile. CONCLUSION: Elevated aminotransferase levels, even within the normal range, were significantly associated with increased risk of all external-cause mortalities, including suicide, and injury.

Eosinophilic gastroenteritis is a rare disease in which the symptoms are associated with eosinophilic infiltration in various layers of the gastrointestinal tract. A 56-year-old man complained of severe abdominal pain after eating yellow tail fish and oyster. There was no peripheral blood eosinophilia in the initial laboratory test. Abdominal computed tomography demonstrated circumferential wall thickening and dilatation of small intestine with ascites. An emergency laparotomy accompanied by segmental resection of the ileum and end-to-end anastomosis was performed. Histologically, there was a dense infiltration of eosinophils throughout the entire layers of ileal wall, through which this case could be diagnosed as eosinophilic enteritis. We did not prescribe systemic glucocorticosteroid, but asked him to avoid fish and oyster. He did not complain of recurrent gastrointestinal symptoms anymore after discharge. This is the case of eosinophilic gastroenteritis with intestinal obstruction requiring emergency surgery, which was developed or aggravated after ingestion of yellow tail fish and oyster that were suspected to be culprit foods. In patients with eosinophilic gastroenteritis, foods which are related to this abnormal condition should be identified and avoided to control this disease and prevent from aggravation or flare-up.

BACKGROUND: In an increasing number of lawsuits doctors lose, despite providing preoperative patient education, because of failure to prove informed consent. We analyzed judicial precedents associated with insufficient informed consent to identify judicial factors and trends related to aesthetic surgery medical litigation. METHODS: We collected data from civil trials between 1995 and 2015 that were related to aesthetic surgery and resulted in findings of insufficient informed consent. Based on these data, we analyzed the lawsuits, including the distribution of surgeries, dissatisfactions, litigation expenses, and relationship to informed consent. RESULTS: Cases were found involving the following types of surgery: facial rejuvenation (38 cases), facial contouring surgery (27 cases), mammoplasty (16 cases), blepharoplasty (29 cases), rhinoplasty (21 cases), body-contouring surgery (15 cases), and breast reconstruction (2 cases). Common reasons for postoperative dissatisfaction were deformities (22%), scars (17%), asymmetry (14%), and infections (6%). Most of the malpractice lawsuits occurred in Seoul (population 10 million people; 54% of total plastic surgeons) and in primary-level local clinics (113 cases, 82.5%). In cases in which only invalid informed consent was recognized, the average amount of consolation money was KRW 9,107,143 (USD 8438). In cases in which both violation of non-malfeasance and invalid informed consent were recognized, the average amount of consolation money was KRW 12,741,857 (USD 11,806), corresponding to 38.6% of the amount of the judgment. CONCLUSIONS: Surgeons should pay special attention to obtaining informed consent, because it is a double-edged sword; it has clinical purposes for doctors and patients but may also be a litigation strategy for lawyers.

PURPOSE: For the treatment of acute appendicitis, a conventional laparoscopic appendectomy (LA) has been widely performed. Recently, the use of single incision laparoscopic surgery (SILS) is increasing because it is believed to have advantages over conventional laparoscopic surgery. In this study, we compared SILS and a conventional LA. METHODS: We analyzed the 217 patients who received laparoscopy-assisted appendectomies between August 2010 and April 2012 at Inje University Sanggye Paik Hospital. One hundred-twelve patients underwent SILS, and 105 patients underwent LA. For the two groups, we compared the operation times, postoperative laboratory results, postoperative pain, hospital stay, and postoperative complications. RESULTS: The patients' demographics, including body mass index, were not significantly different between the two groups. There were 6 perforated appendicitis cases in the SILS group and 5 cases in the LA group. The mean operative time in the SILS group was 65.88 +/- 22.74 minutes whereas that in the LA group was 61.70 +/- 22.27 minutes (P = 0.276). There were no significant differences in the mean hospital stays, use of nonsteroidal antiinflammatory drugs, and wound infections between the two groups. CONCLUSION: Postoperative pain, complications and hospital stay showed no statistically significant differences between the SILS and the LA groups. However, our SILS method uses a single trocar and two latex tubes, so cost savings and reduced interference during surgery are expected.

Humoral hypercalcemia of malignancy (HHM) is rarely associated with cholangiocarcinoma (CC), and represents dismal prognosis. A 63-year-old male was admitted for evaluation of an intrahepatic mass. He was diagnosed with HHM associated with locally advanced CC. As the tumor responded to the concurrent chemoradiotherapy with capecitabine and cisplatin, serum calcium level was normalized. However, according to the disease progression, he suffered recurrence of HHM and he expired approximately one year after initial diagnosis. A 68-year-old male who presented with abdominal pain was diagnosed with metastatic CC. After the eighth cycle of gemcitabine and cisplatin, progression of the disease was found with HHM. He was treated with the best supportive care, until his demise approximately one month after the diagnosis of HHM. We report on two cases of HHM associated with CC that demonstrate strong correlation between hypercalcemia and disease burden.

Autosomal dominant polycystic kidney disease (ADPKD) is a systemic disorder associated with various extrarenal complications. The major cardiovascular complications of ADPKD include valvulopathies and vascular ectasia. A 64-year-old man who was diagnosed with ADPKD seven years previously was admitted to our hospital for heart failure. Pelvic computed tomography revealed multiple variable-sized cysts in both kidneys. Transthoracic echocardiography showed enlargement of the left ventricle and left atrium. Severe mitral regurgitation and moderate aortic regurgitation with annuloaortic ectasia were observed. The left main coronary artery was dilated. The patient had various cardiovascular features associated with ADPKD.

BACKGROUND: Lung cancer was the second highest absolute cancer incidence globally and the first cause of cancer mortality in 2014. Indoor radon is the second leading risk factor of lung cancer after cigarette smoking among ever smokers and the first among non-smokers. Environmental burden of disease (EBD) attributable to residential radon among non-smokers is critical for identifying threats to population health and planning health policy. METHODS: To identify and retrieve literatures describing environmental burden of lung cancer attributable to residential radon, we searched databases including Ovid-MEDLINE, -EMBASE from 1980 to 2016. Search terms included patient keywords using ‘lung’, ‘neoplasm’, exposure keywords using ‘residential’, ‘radon’, and outcomes keywords using ‘years of life lost’, ‘years of life lost due to disability’, ‘burden’. Searching through literatures identified 261 documents; further 9 documents were identified using manual searching. Two researchers independently assessed 271 abstracts eligible for inclusion at the abstract level. Full text reviews were conducted for selected publications after the first assessment. Ten studies were included in the final evaluation. REVIEW: Global disability‐adjusted life years (DALYs)(95 % uncertainty interval) for lung cancer were increased by 35.9 % from 23,850,000(18,835,000-29,845,000) in 1900 to 32,405,000(24,400,000-38,334,000) in 2000. DALYs attributable to residential radon were 2,114,000(273,000-4,660,000) DALYs in 2010. Lung cancer caused 34,732,900(33,042,600 ~ 36,328,100) DALYs in 2013. DALYs attributable to residential radon were 1,979,000(1,331,000-2,768,000) DALYs for in 2013. The number of attributable lung cancer cases was 70-900 and EBD for radon was 1,000-14,000 DALYs in Netherland. The years of life lost were 0.066 years among never-smokers and 0.198 years among ever-smoker population in Canada. CONCLUSION: In summary, estimated global EBD attributable to residential radon was 1,979,000 DALYs for both sexes in 2013. In Netherlands, EBD for radon was 1,000–14,000 DALYs. Smoking population lost three times more years than never-smokers in Canada. There was no study estimating EBD of residential radon among never smokers in Korea and Asian country. In addition, there were a few studies reflecting the age of building, though residential radon exposure level depends on the age of building. Further EBD study reflecting Korean disability weight and the age of building is required to estimate EBD precisely.

BACKGROUND/AIMS: The exercise ECG test (XECG) and computed tomography coronary angiography (CTCA) have been used widely in initial evaluations of coronary artery disease (CAD) in real-world practice. In this study, we compared the diagnostic power of CTCA and XECG, based on conventional coronary angiography (CCA). METHODS: We enrolled 589 consecutive patients retrospectively who had been examined with both XECG and CTCA for the evaluation of CAD in outpatient clinics. Significant stenosis was defined as more than 50% diameter stenosis. Triage to CCA and/or revascularization treatment (RT) by the results of XECG and CTCA and the diagnostic accuracy of both exams, based on CCA, were investigated. RESULTS: In the 589 patients, 107 (19%) were triaged to CCA for further evaluation; in 77 (12.8%) significant stenosis was detected on CCA. Also, 65 (11%) patients underwent RT. In the CTCA results, 120 patients had significant stenosis. Of them, 58 (48%) and 75 (62%) patients were triaged to RT and CCA, respectively. Based on the XECG, 115 positive patients were triaged to RT and CCA (23 [20%]/41 [35%]). Among 107 patients with CCA, the sensitivity, specificity, positive predictive value, and negative predictive value for significant stenosis on CCA of CTCA were 89.9%, 74.0%, 90.6%, and 71.4%, respectively, and those of XECG were 50.0, 67.9, 78.0, and 37.3, respectively. The kappa value of CCA and CTCA was 0.62 (p < 0.001) and that of CCA and XECG was 0.145 (p = 0.113). CONCLUSIONS: In real-world practice, CCA was decided on more frequently, based on CTCA. CTCA showed better diagnostic accuracy than XECG.

Purpose: Microbiota manipulation through selected probiotics may be a promising tool to prevent cancer development as well as onset, to improve clinical efficacy for cancer treatments. The purpose of this study was to evaluate change in microbiota composition after-probiotics supplementation and assessed the efficacy of probiotics in improving quality of life (QOL) in postoperative cancer patients. Methods: Stool samples were collected from 30 cancer patients from February to October 2020 before (group I) and after (group II) 8 weeks of probiotics supplementation. We performed 16S ribosomal RNA gene sequencing to evaluate differences in gut microbiota between groups by comparing gut microbiota diversity, overall composition, and taxonomic signature abundance. The health-related QOL was evaluated through the EORTC Quality of life Questionnaire Core 30 questionnaire. Results: Statistically significant differences were noted in group II; increase of Shannon and Simpson index (P = 0.004 and P = 0.001), decrease of Bacteroidetes and Fusobacteria at the phylum level (P = 0.032 and P = 0.014, retrospectively), increased of beneficial bacteria such as Weissella (0.096% vs. 0.361%, P < 0.004), Lactococcus (0.023% vs. 0.16%, P < 0.001), and Catenibacterium (0.0% vs. 0.005%, P < 0.042) at the genus level. There was a significant improvement in sleep disturbance (P = 0.039) in group II. Conclusion Gut microbiota in cancer patients can be manipulated by specific probiotic strains, result in an altered microbiota. Microbiota modulation by probiotics can be considered as part of a supplement that helps to increase gut microbiota diversity and improve QOL in cancer patients after surgery.
