BACKGROUND: Severe mitral regurgitation is a common clinical entity that can lead to progressive, irreversible left ventricular dysfunction, and thus should be corrected in proper stage of life. Authors have conducted this investigation to assess left ventricular function after mitral valve operation and to determine the predicting factors. METHODS AND RESULTS: The echocardiographic parameters, specifically left ventricular ejection fraction, shortening fraction, end-systolic dimension and volume, and end-diastolic dimension and volume were measured in preoperative and postoperative period of congenital mitral regurgitation patients (n=60), between March 1992 and March 1998. After correction of severe mitral regurgitaion, left ventricular ejection fraction and shortening fraction decreased significantly (p<0.001 and p<0.05 respectively). Furtheremore, after reoperation of recurred mitral regurgitation, left ventricular ejection fraction and shortening fraction decreased significantly (p<0.05). Left ventricular ejection fraction and shortening fraction in mitral valve reoperation group (n=23) is significantly lower than those in non-reoperation group (n=37) in both preoperative and postoperative period (p<0.05). Left ventricular ejection fraction and shortening fraction is also significantly lower in mitral valve replacement group (n=20) than in mitral valvuloplasty group (n=40)(p<0.05). Severe postoperative left ventricular dysfunction led to dilated cardiomyopathy in 5 patients. Postoperative left ventricular end systolic dimension increased significantly in reoperation group and DCMP group respectively (p<0.05). CONCLUSION: After surgical correction of mitral regurgitation, left ventricular dysfunction is frequent and carries a poor prognosis. Postoperative left ventricular dysfunction can be predicted by preoperative ejection fraction, shortening fraction and systolic diameter. Therefore surgical therapy before the onset of left ventricular dysfunction is recommended.

PURPOSE: Subtotal distal gastrectomy has been accepted as the standard treatment for early gastric cancer that's developed on the gastric body. EMR and ESD have been introduced to minimize the incidence of postgastrectomy syndrome, but these procedures can not detect lymph node metastasis and they have a risk for gastric perforation. Segmental gastrectomy has recently been applied for treating early gastric cancer, but its usefulness has not been clarified. The aim of this study was to compare segmental gastrectomy and distal gastrectomy with Billroth I reconstruction for treating early gastric cancer that's developed on the gastric body. MATERIALS AND METHODS: We performed a retrospective review of all the patients who were diagnosed as having early gastric cancer that developed on the gastric body at Chungnam National University Hospital from January 2004 through July 2007. During this period, 41 patients received segmental gastrectomy and 40 patients underwent subtotal distal gastrectomy. All the patients were studied via a biannual review of the body systems, a physical examination, endoscopy, computed tomography and the laboratory findings. RESULTS: There were no significantly differences of the clinicopathologic characteristics between the two groups. The changes of the nutritional status (Hb, TP, Alb and TC) and the body weight change were not significantly different between the 2 groups. There were significantly more residual food in the SG group than that in the SDG group (RGB classification, Residual>Grade 2), but there were no differences for epigastric discomfort (P>0.05). Esophagitis developed at a similar rate for both two groups (LA classification, >Grade A), and bile reflux was found in only one patient of each group. CONCLUSION: We expected the reduction of esophagitis and gastritis and the improvement of nutritional status according to the type of procedure. Yet the results of our study showed no significant differences between the two study groups. More patients and a longer follow up time are needed for determining the advantage sand disadvantages of segmental gastrectomy.

PURPOSE: The purpose of this cross-sectional study was to assess the nutritional states and investigate the energy intake of tube-fed patients with severe neurodevelopmental disability. METHODS: Eighty six tube-fed patients with severe neurodevelopmental disability were studied. Heights were measured by flexible scale segmentally. Nutritional parameters of weight, triceps skin- fold thickness and mid-arm circumference were also measured. Total caloric intakes through the tube were calculated. RESULTS: The anthropometric results showed that nutritional states of tube-fed patients with severe neurodevelopmental disability were poor. The mean daily caloric intake was much less than daily energy requirement (mean=45.2% of requirement). The caloric intake was 7.2 kcal/height (cm), 57.0 kcal/weight (kg). Height was more related with caloric intake (r=0.476) than weight (r=0.263). CONCLUSION: These results provide that tube-fed patients with severe neurodevelopmental disability were growth retarded and their energy intakes were much less than daily energy requirements. The preliminary evidence was that they need adequate nutritional supply.

OBJECTIVE: To prevent the occurrence of CV events such as MI and stroke among professional drivers in Korea, bus drivers were compared to other occupations through the Framingham risk scoring system (FRS) or metabolic syndrome (MS) of cardiovascular disease (CVD) risk assessment methods. METHODS: In October 2012, a health examination survey was conducted for 443 male bus drivers in a big city. Their CVD risk factors were compared to those of a 'total employed' (A group) and 'crafts and machine operators' (B group) extracted from Fifth Korea National Health and Nutrition Examination Survey (KNHANES, 2010) data by using FRS and MS. We calculated proportions of the CVD risk factors distribution between bus drivers and the A, B groups by the bootstrapping method. The Odds ratio (OR) between CV event risk combining MS with CHD equivalent risk of FRS and occupational factors like shift patterns and professional driving duration/age ratios (PDAR) of bus drivers was calculated through multinominal logistic regression. RESULTS: The proportion of BMI > or = 25 kg/m2 was 53.9% and waist circumference > or = 90cm was 40.9% among bus drivers. Hypertension and MS prevalence of bus drivers was 53.3%, 49.9% which is higher than 17.6%, 22.6% in the A group and 19.7%, 23.8% in the B group respectively. OR of high CV event risk in alternate shift was 2.58 (95% CI 1.33~5.00) in comparison with double shift pattern and OR in PDAR > or = 0.5 was 2.18 (95% CI 1.15~4.14). CONCLUSION: Middle aged male drivers in a big city of Korea stand a higher chance of developing CV event than other professions of the same age.

Propofol is an intravenous hypnotic agent that is generally used for sedation in the intensive care unit and for induction of anesthesia during minimally invasive surgery, endoscopy, and plastic surgery in local clinics. Low blood pressure and transient apnea might occur under propofol sedation, whereas stress-induced cardiomyopathy is a very rare complication. We herein describe a case involving a 25-year-old woman without cardiovascular risk factors who developed stress-induced cardiomyopathy after propofol injection for anesthesia and was treated with conservative treatment. This case reminds us that clinicians should consider the possible occurrence of stress-induced cardiomyopathy after anesthesia using propofol, even in patients without cardiovascular risk factors.

OBJECTIVES: To identify adverse health effects due to air pollution derived from a cement plant in Korea. The ventilation impairment in residents around a cement plant was compared to another group through a pulmonary function test (PFT). METHODS: From June to August of 2013, both a pre and post-bronchodilator PFT was conducted on a "more exposed group (MEG)" which consisted of 318 people who lived within a 1 km radius of a cement plant and a "less exposed group (LEG)" which consisted of 129 people who lived more than 5 km away from the same plant. The largest forced expiratory volume in a one second (FEV1) reading and a functional residual capacity (FVC) reading were recorded after examining the data from all of the usable curves that were agreed upon as valid by PFT experts of committee of National Institute of Environmental Research. The global initiative for chronic obstructive lung disease (GOLD) criteria for COPD, defined the FEV1/FVC ratio < 0.7 as the obstructive type, and the FEV1/FVC ratio >== 0.7 and FVC% predicted < 80% were as the restrictive type. The FVC% predicted value was estimated using Korean equation. We compared the proportion of lung function impairments between the MEG and the LEG by using a chi-square, and estimated the OR of obstructive and restrictive ventilation impairments by logistic regression. RESULTS: The obstructive type impairment proportion was 9.7% in the MEG, whereas it was 8.5% in the LEG. The restrictive type was 21.6% in the MEG which was more than the 12.4% of the LEG. The odds ratio (OR) of total ventilation impairment in the MEG was 2.63 (95% CI 1.50 ~ 4.61) compared to the LEG. The OR of obstructive type in the MEG was 1.60 (95% CI 0.70 ~ 3.65), the smoking history was 3.10 (CI 1.10 ~ 8.66) whereas OR of restrictive type in the MEG was 2.55 (95% CI 1.37 ~ 4.76), the smoking history was 0.75 (95% CI 0.35 ~ 1.60) after adjusting for sex and age. Level of exposure to particulate played a role in both types. However, it appeared to be a significant variable in restrictive type, while smoking history was also an important variable in obstructive type. CONCLUSION: Although this study is a limited cross-section study with a small number of subjects, ventilation impairment rate is higher in the MEG. There might be a possibility that it is due to long-term exposure to particulate dust generated by the cement plant.

BACKGROUND: To evaluate the diagnostic accuracy of EBT(Electron Beam Tomography) in the diagnosis of conotruncal anomaly and to determine whether it can be used as a substitute for cardiac angiography. MATERIAL AND METHOD: 20 patients(11M & 9F) with TOF(n=7, pulmonary atresia 2), DORV(n=7), complete TGV(n=4), & corrected TGV(n=2) were included. The age ranged from 7 days to 26 years(median 60 days). We analyzed the sequential chamber localization, the main surgical concenrn in each disease category (PA size, LVED volume and coronary artery pattern for TOF& pulmonary atresia, the LV mass, LVOT obstruction, coronary artery pattern for complete TGV, and type of VSD and TV-PV distance for DORV, etc) and other associated anomalies(e.g., VSD, arch anomalies, tracheal stenosis, etc). Those were compared with the results of echocardiography(n=19), angiography (n=9), and surgery(n=11). The interval between EBT and echocardiography/angiography was within 20/11 days, respectively except for an angiography in a patient with corrected TGV (48 days). RESULT: EBT correctly diagnosed the basic components of conotruncal anomalies in all subjects, compared to echocardiography, angiography or surgery. These included the presence, type and size of VSD(n=20), pulmonic/LV outflow tract stenosis(n=15/2), relation of great arteries and the pattern of the proximal epicardial coronary arteries(16 out of 20). EBT proved to be accurate in quantitation of the intrapericardial and hilar pulmonary arterial dimension and showed high correlation and no difference compared with echocardiography, angiography, or surgery(p>0.05) except for left pulmonary arterial & ascending arterial dimension by echocardiography. LVED volume in seven TOF(no difference: p>0.05 & high correlation: r=0.996 with echocardiography), and LV mass in 4 complete TGV were obtained. Additionally, EBT enabled the cdiagnosis of subjlottic tracheal stenosis and tracheal bronchus in 1 respectively. Some peripheral PA stenosis were not detected by echocardiography, while echocardiography appeared to be slightly more accurate than EBT in detecing ASD or PDA. CONCLUSIONS: EBT can be a non-invasive and accurate modality of for the evaluation of most anatomical alteration including peripheral PS or interruption in patients with conotruncal anomalies. Combined with echocardiography, EBT study provides sufficient information for the palliative or total repair of anomalies.

Increased fat intake is known to be a major cause of prostate cancer. In this study, we investigated the effect of dietary high fat on prostate intraepithelial neoplasia using transgenic adenocarcinoma mouse prostate (TRAMP) mice. Six-week-old male TRAMP mice were fed AIN93G (control group, 4.0 kcal/kg, n=6) and AIN93G-HFD (experimental group, 4.8 kcal/kg, n=7) for 10 weeks. Prostate histopathology, urogenital tract (UGT) weight, epididymal white adipose tissue weight, argyrophilic nucleolar organizer regions (AgNORs) counts, and serum leptin levels were examined. AIN93G-HFD fed group showed progressed neoplastic lesions in the prostate (P<0.05) compared to AIN93G fed group. AIN93G-HFD intake resulted in a increase in the weight of UGT (P<0.05) and epididymal white adipose tissue. The number of Ag-NOR positive dots significantly increased in each prostate lobe and final serum leptin levels in AIN93G-HFD fed group were about twice those of AIN93G fed group (P<0.05). Dietary high fat was related to the prostate cancer progression in the early stage of TRAMP mice and increased serum leptin levels, suggesting that the regulation of dietary components could delay the progression of prostate cancer.
