Purpose:
This study aimed to evaluate the natural growth of subepithelial tumors of the small bowel detected on CT.
Materials and Methods:
Consecutive patients who were suspected of having subepithelial tumors of the small bowel between January 2005 and December 2020 were reviewed. Eligible patients with suspected small (< 30 mm) subepithelial tumors on at least two CT evaluations were included in the analysis. The patients’ data on demographic characteristics, tumoral characteristics, and tumoral size changes during the follow-up were collected.
Results:
This study included 64 patients with suspected small subepithelial tumors (n = 64) of the small bowel. After a median follow-up of 15.8 months, the diameter and volume growth rates were 0.02 mm/month and 1.5 mm3/month, respectively. A significant correlation was observed between the initial size and the growth rate of the small bowel subepithelial tumors. The group of large-sized tumors (initial diameter ≥ 10 mm) tended to show lobulated contours, heterogeneous enhancement, and necrotic changes more frequently than the group of small-sized tumors (initial diameter < 10 mm).
Conclusion
Small bowel subepithelial tumors measuring less than 10 mm grew more slowly than those measuring 10–30 mm.

PURPOSE: We performed this study to determine (1) whether the levels of inflammatory mediators, including matrix metalloproteinase-9 (MMP-9) and intercellular adhesion molecule-3 (ICAM-3), in gastric fluid (GF) in premature newborns are associated with those in amniotic fluid (AF) in their mothers and (2) whether the levels of the inflammatory mediators in newborn GF are associated with the presence of intrauterine inflammation (IUI). METHODS: Sixty-two pairs of pregnant women and their premature newborns born at <35 weeks' gestation by cesarean delivery were enrolled in this study. AF and newborn GFs were obtained during cesarean section procedures. Levels of MMP-9, ICAM-3, interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-alpha (TNF-alpha) were measured and compared between the AF and newborn GFs in each dyad, according to the presence or absence of chorioamnionitis (CA), preterm prelabor rupture of membranes (PPROM), and preterm labor (PTL). RESULTS: The levels of MMP-9, ICAM-3, IL-6, IL-8, and TNF-alpha in newborn GF were significantly correlated with those in AF in each dyad. The premature newborns and their mothers with CA had significantly higher GF MMP-9, IL-8, and TNF-alpha levels than those without CA. Those with PPROM or PTL showed similar findings in terms of GF MMP-9, IL-8, and TNF-alpha levels. CONCLUSION: The newborn GF immediately after birth can be a useful alternative source of information on whether a premature infant has been exposed to IUI at the time of delivery.

On 16 April 2014, the Sewol ferry, carrying 476 people, sank in the ocean off the south coast of South Korea. Two hundred and ninety five are confirmed dead and 9 remain missing. The Korean Neuropsychiatric Association (KNPA) set up a Disaster Mental Health Committee (KDMHC) for out-reach services and to provide general strategies for promoting mental health and resilience. Mem bers of KDMHC and Volunteering Psychiatrists of the KNPA had participated in disaster mental health services organized by Gyeonggi-Ansan disaster mental health support team. Their activities were composed of psychoeducation, supportive individual and familial counseling and referring service to professional institutes. This report has described the outline of the initial and acute mental health care responses by KDMHC and volunteers among KNPA members.

PURPOSE: Intrauterine inflammation (IUI) is a leading cause of preterm delivery. Although matrix metalloproteinase-8 (MMP-8) and intercellular adhesion molecule-1 (ICAM-1) are known to be related with IUI, it has not been fully elucidated whether MMP-9 or ICAM-3 is associated with IUI. We performed this study to determine whether the levels of tumor necrosis factor-alpha (TNF-alpha), MMP-9 and ICAM-3 in umbilical cord blood of preterm infants are associated with chorioamnionitis, funisitis or bronchopulmonary dysplasia. METHODS: Eighty-two pairs of pregnant women and their preterm newborns <35 weeks gestation were enrolled. Levels of TNF-alpha, MMP-9 and ICAM-3 in umbilical cord blood were measured using immunoassays and compared with results of histological examination of placenta and clinical data of the study participants. RESULTS: The level of MMP-9 in umbilical cord blood was significantly associated with the presence of funisitis (P =0.007). The level of TNF-alpha in umbilical cord blood was significantly associated with the development of bronchopulmonary dysplasia (P =0.030). However, presence of chorioamnionitis or funisitis was not associated with development of bronchopulmonary dysplasia. With the establishment of receiver operating characteristic (ROC) curve, the best cut-off value for umbilical blood MMP-9 was 99.42 pg/mL in identification of funisitis. The area under a constructed ROC curve for prediction of funisitis was 0.847 (standard error, 0.112; 95% confidence interval, 0.750-0.917). CONCLUSION: Measurement of MMP-9 concentration in umbilical cord blood may be an alternative way to predict whether a preterm infant has been exposed to IUI. Further study with larger numbers of subjects will be necessary to elucidate the association between the presence of IUI and neonatal adverse outcome.

PURPOSE: We aimed to determine whether Autism Spectrum Disorder (ASD) would show neural abnormality of the social reward system using functional MRI (fMRI). MATERIALS AND METHODS: 27 ASDs and 12 typically developing controls (TDCs) participated in this study. The social reward task was developed, and all participants performed the task during fMRI scanning. RESULTS: ASDs and TDCs with a social reward learning effect were selected on the basis of behavior data. We found significant differences in brain activation between the ASDs and TDCs showing a social reward learning effect. Compared with the TDCs, the ASDs showed reduced activity in the right dorsolateral prefrontal cortex, right orbitofrontal cortex, right parietal lobe, and occipital lobe; however, they showed increased activity in the right parahippocampal gyrus and superior temporal gyrus. CONCLUSION: These findings suggest that there might be neural abnormality of the social reward learning system of ASDs. Although this study has several potential limitations, it presents novel findings in the different neural mechanisms of social reward learning in children with ASD and a possible useful biomarker of high-functioning ASDs.

Prediction of malignancy or invasiveness of branch duct type intraductal papillary mucinous neoplasm (Br-IPMN) is difficult, and proper treatment strategy has not been well established. The authors investigated the characteristics of Br-IPMN and explored its malignancy or invasiveness predicting factors to suggest a scoring formula for predicting pathologic results. From 1994 to 2008, 237 patients who were diagnosed as Br-IPMN at 11 tertiary referral centers in Korea were retrospectively reviewed. The patients' mean age was 63.1 +/- 9.2 yr. One hundred ninty-eight (83.5%) patients had nonmalignant IPMN (81 adenoma, 117 borderline atypia), and 39 (16.5%) had malignant IPMN (13 carcinoma in situ, 26 invasive carcinoma). Cyst size and mural nodule were malignancy determining factors by multivariate analysis. Elevated CEA, cyst size and mural nodule were factors determining invasiveness by multivariate analysis. Using the regression coefficient for significant predictors on multivariate analysis, we constructed a malignancy-predicting scoring formula: 22.4 (mural nodule [0 or 1]) + 0.5 (cyst size [mm]). In invasive IPMN, the formula was expressed as invasiveness-predicting score = 36.6 (mural nodule [0 or 1]) + 32.2 (elevated serum CEA [0 or 1]) + 0.6 (cyst size [mm]). Here we present a scoring formula for prediction of malignancy or invasiveness of Br-IPMN which can be used to determine a proper treatment strategy.

Constitutional trisomy 8 mosaicism (CT8M) is a relatively rare aneuploidy in humans with characteristic phenotypes including typical craniofacial feature (such as deformed skull, prominent forehead, low-set and/or dysplastic ears), skeletal malformation, cardiac anomaly, renal malformation, cryptochidism, varying degree of developemental delay. Due to the extremely variable phenotypic and cytogenetic expression, CT8M has gone undiagnosed in certain patients. We report a 28-year-old women with secondary amenorreha without characteristic CT8M phenotype. Chromosomal analysis showed a CT8M (47,XX,+8[9]/46,XX[41]).

BACKGROUND: The purpose of this study is to know the healthcare-associated infection (HAI)s in small and medium sized hospitals, less than 400 beds. METHODS: We had web based surveillance for HAIs in 27 hospitals from August to October 2010. The surveillance performed in 1-2 ICUs and 1 general ward in each hospitals by CDC definition. And for the multi-drug resistant organisms (MDROs), we reviewed all of blood culture results. RESULTS: We identified 319 HAIs among 269,436 patients days. The HAIs rate was 1.18 (CI 1.05-1.32)/1,000 patient-days. Urinary tract infection was the most common HAI (52.4%) in this study followed by pneumonia (18.9%), blood-stream infections (14.2%), surgical site infection (7.9%), and others (6.6%). There were 76.5% of device associated infections in UTI, 46.7% in BSI, and 18.3% in pneumonia. The rate of HAIs in ICU was higher than that of in general ward (4.6 vs 0.9/1,000 patient-days). However, the indwelling catheter associated urinary tract infection rate was lower in ICU (2.6 vs 4.4/1,000 device days). There were no significant differences in central line-associated blood stream infection rate (1.5 vs 1.8) and ventilator-associated pneumonia rate (3.0 vs 0.0). The common microorganisms found in HAIs were Escherichia coli (19.8%), Staphylococcus aureus (13.1%), and Pseudomonas aeruginosa (12.7%). Moreover, 90.9% of S. aureus were resistant to methicillin, and 38.2% of P. aeruginosa and 44.4% of Acinetobacter baumannii were resistant to imipenem. Total of 66 MDROs were isolated from blood culture and the result shows that the MRSA was 84.6% (56 case), carbapenmen-resistant Acinetobacter spp. was 10.6% (7 case), and vancomycin-resistant enterococci was 4.6% (3 case). CONCLUSION: The characteristics of HAIs in small and medium sized hospitals will be contributed to the decision making of governance policy for infection control and to provide comparable data for these hospitals.

BACKGROUND: Sleep is an essential restorative physiologic phenomenon. Impaired sleep results in significant negative effect to the health. Symptoms like sleep initiation difficulty, frequent awakening, severe snoring have related to poor sleep quality. We studied frequency and compared the characteristics of common sleep disorders at family practice. METHODS: We surveyed patients over 18 years of age and their guardians who visited 16 familial practices for 6 days. We investigated sleep characteristics, frequency of sleep disorder and associated factors by questionnaires and analyzed by frequency analysis, Spearman's correlation coefficient, multiple logistic regression. RESULTS: We enrolled 1,117 participants. Older participants were more likely to report early sleep onset and off time, short sleep duration. Mean number of awakening during a typical night is 1.69. Female complained difficulties in initiation and maintenance of sleep more than male. A total of 32.5% had these insomnia symptoms and related to hypertension, stroke, stress, arthralgia, depression, urological disorder. 31.1% had excessive daytime sleepiness, related to stress, arthralgia, depression. Loud snoring and gasp for breath showed positive correlation between male, high BMI. Disrupted sleep over 3 times was related to old age, female, diabetes, hypertension, stroke, stress, arthralgia, depression. Restless leg syndrome were high in elderly, high BMI, stress, arthralgia and depression. CONCLUSION: About one in three who visit in primary medical practice have sleep disorder symptoms like insomnia, daytime fatigue, snoring. 3% of them have gasp for breath, 8% have restless leg syndrome.

PURPOSE: Experimental animal models are useful training methods for liver transplantation, despite of ethical issues. The aims of this study are to examine the technical feasibility of living donor liver transplantation in pigs and to address the ethical problems. METHODS: Eight pigs were used in this experiment. The pig liver was divided via a left hemi-hepatectomy without inflow occlusion. The GORE-TEX(R) Vascular Graft was used as a replacement for the inferior vena cava during the graft. After the bench technique, the remnant right lobe of the pig was removed. During the anhepatic phase, an abdominal aortic clamp in combination with general hypothermia was applied, instead of using a conventional bypass procedure. RESULTS: Anhepatic time was 41.3+/-7.0 min and cold ischemic time was 200.3+/-29.4 min. The 1(st), 4(th), and 8(th) pig died because of declamping shock and arrhythmia on releasing the abdominal aortic clamp. Three pigs had five postoperative complications: pneumonia, gastrointestinal bleeding, IVC thrombosis, portal vein thrombosis, and bile duct stricture. The 6th pig received a hepaticojejunostomy due to stricture of the anastomosis site at 37 days after transplantation. CONCLUSION: Pigs are economically and ethically more convenient compared to primate models. For auto-liver transplantation, no immunotherapy was needed. The pigs lived relatively long, allowing operative faults to be detected and studied. This experimental model will be useful training for living donor liver transplantation.
