Cardiac arrest (CA) in children is associated with high mortality rates. In Korea, cohort studies regarding the outcomes of pediatric CAs are lacking, especially in emergency departments (EDs) or in-hospital settings. This study was conducted to examine the trends in epidemiology and survival outcomes in children with resuscitation-attempted CAs using data from a cross-sectional, national, ED-based clinical registry. We extracted cases in which cardiopulmonary resuscitation and/or manual defibrillation were performed according to treatment codes using the National Emergency Department Information System (NEDIS) from 2008 to 2012. The total number of ED visits registered in the NEDIS during the 5-yr evaluation period was 20,424,530; among these, there were 2,970 resuscitation-attempted CAs in children. The annual rates of pediatric CAs per 1,000 ED visits showed an upward trend from 2.81 in 2009 to 3.62 in 2012 (P for trend = 0.045). The median number of estimated pediatric CAs at each ED was 7.8 (25th to 75th percentile, 4 to 13) per year. The overall rates for admission survival and discharge survival were 35.2% and 12.8%, respectively. The survival outcome of adults increased substantially over the past 5 yr (11.8% in 2008, 11.7% in 2010, and 13.6% in 2012; P for trend = 0.001); however, the results for children did not improve (13.6% in 2008, 11.4% in 2010, and 13.7% in 2012; P for trend = 0.870). Conclusively, we found that the overall incidence of pediatric CAs in EDs increased substantially over the past 5 yr, but without significantly higher survival outcomes.

Purpose:
This study was conducted to analyze the social factors influencing the ‘authenticity of suicidal ideation’ based post-suicidal care programs in emergency departments (EDs).
Methods:
This retrospective study was an analysis using the data of patients who had attempted suicide and visited the ED in tertiary urban hospitals from January 1, 2016, to December 31, 2018. The variables examined included gender, age, history of previous psychiatric disease, suicide method, and the number of previous attempts. Univariate and multivariate logistic regression analyses were conducted to identify factors influencing the registration rate for the community-based post-suicide care program.
Results:
Overall,1,460 suicides were analyzed, 177 (1.16%) showed a high authenticity of suicide. The social factors influencing the authenticity of suicide intent were the unmarried status of men and women, joblessness, history of mental illnesses, more than two previous suicide attempts, the influence of alcohol, and an attempt to commit suicide after midnight more specifically between 24:00 to 6:00 hours in the morning (p<.05). The factors influencing the severity of the condition of high authenticity suicide patients were low Glasgow coma scores (12 points or less), lactate levels, and oxygen saturation observed in the patients who were admitted to the intensive care unit for treatment and died (p<.05).
Conclusion
The need for evidence-based preventive measures and early assessment tools at the emergency medicine level is emphasized to reduce the rate of suicide attempts. If the results of this study are used in the management of suicide prevention, the evaluation of the authenticity of suicide intent will be more likely to be made at the emergency medicine level, allowing the severity to be assessed earlier.

A burnt-out prostate cancer tumor is a very rare clinical entity. The term 'burnt-out' refers to a primary tumor that has spontaneously and nearly completely regressed without treatment. Since metastasis of prostate cancer is usually encountered in the presence of advanced disease, distant metastasis with an undetectable primary tumor is very rare. We report herein a case of a burnt-out prostate cancer tumor that metastasized to the thoracic (T) spine and caused cord compression. A 66-year-old man visited the Emergency Department due to weakness of both legs for the past two days. His blood and urine tests were normal at the time. His spine magnetic resonance imaging (MRI) scans looked like bone metastasis that involved the T-7 vertebral body and a posterior element, and caused spinal cord compression. Other images, including from the brain MRI, neck/chest/abdomino-pelvic computed tomography (CT) scan and 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) and endoscopy, revealed no lesions that suggested malignancy. After total corpectomy T-7 and screw fixation/fusion at T5 to T10, the pathology report revealed a metastatic carcinoma that was strongly positive for prostate-specific antigen (PSA). The serum PSA value was 1.5 ng/mL. The transrectal 12-core prostate biopsy and ultrasonography showed no definitive hypoechoic lesion, but one specimen had slight (only 1%) adenocarcinoma with a Gleason score of 6 (3+3). The final diagnosis was burned-out prostate cancer with an initial normal PSA value. Although metastatic disease with an unknown primary origin was confirmed, a more aggressive approach in seeking the primary origin could provide a more specific treatment strategy and greater clinical benefit to patients.

BACKGROUND: An epidermal cyst is a common keratin-filled epithelial-lined cyst. The treatment of choice for epidermal cysts is surgical excision. If the cyst becomes ruptured, incision and drainage with oral antibiotic therapy or intralesional steroid injection are required. OBJECTIVE: To analyze the dermoscopic features that can differentiate between ruptured and unruptured epidermal cysts. METHODS: The clinical and dermoscopic features of the pathologically confirmed epidermal cysts of two subgroups of 38 patients, 20 with unruptured cysts and 18 with ruptured cysts, were reviewed. RESULTS: With regard to the dermoscopic features, an ivory- white background color and punctum were commonly found in both groups (p>0.05). The unruptured-cyst group showed higher frequencies of pore sign (p<0.05), blue-white veil (p>0.05), no vascular structure, and arborizing telangiectasia (p<0.05), but the ruptured-cyst group usually had red lacunae (p>0.05) and peripheral linear branched vessels (with an erythematous rim) (p<0.05). CONCLUSION: Dermoscopy is helpful in differentiating between ruptured and unruptured epidermal cysts.

BACKGROUND/AIMS: Primary biliary cirrhosis (PBC) is a slowly progressing autoimmune disease of the liver that is characterized by portal inflammation and immune-mediated destruction of the intrahepatic bile ducts. Serum total bilirubin is one of the various prognostic factors that have been proposed. A recent study found that PBC with accompanying autoimmune hepatitis (AIH) carries a negative prognosis. This study examined the clinical characteristics of PBC and analyzed the factors that affect its prognosis. METHODS: Patients diagnosed with PBC between January 1998 and December 2010 based on clinical and histopathological findings were compiled and analyzed retrospectively. RESULTS: Among 27 patients, 24 (1 male and 23 females, ages 50.0+/-9.3 years) were followed up. The follow-up period was 8.6+/-0.9 years. Of the 24 patients, 9 patients progressed to liver cirrhosis (LC). Comparison between patients who did and did not progress to LC revealed statistically significant differences in the patients' serum total bilirubin (2.7+/-1.8 vs. 0.8+/-0.4, P=0.012), the Mayo risk score (5.1+/-0.7 vs. 3.9+/-0.6, P=0.001), the revised IAHG (International Autoimmune Hepatitis Group) score (9.2+/-2.3 vs. 5.4+/-3.0, P=0.004) and frequency of AIH overlap (5/9 [55.6%] vs. 0/15 [0%], P=0.001) at the time of diagnosis. CONCLUSIONS: We propose that serum total bilirubin, the Mayo risk score, and the revised IAHG score at the time of diagnosis are helpful for predicting PBC prognosis. In particular, since all of the patients with accompanying AIH progressed to LC, the presence of overlap syndrome at the time of diagnosis is helpful for predicting PBC prognosis and providing an adequate treatment.

BACKGROUND/AIMS: We investigated the frequency of occult hepatitis B virus (HBV) infection in anti-hepatitis C virus (HCV)-positive individuals and the effects of occult HBV infection on the severity of liver disease. METHODS: Seventy-one hepatitis B virus surface-antigen (HBsAg)-negative patients were divided according to their HBV serological status into groups A (anti-HBc positive, anti-HBs negative; n=18), B (anti-HBc positive, anti-HBs positive; n=34), and C (anti-HBc negative, anti-HBs positive/negative; n=19), and by anti-HCV positivity (anti-HCV positive; n=32 vs. anti-HCV negative; n=39). Liver biopsy samples were taken, and HBV DNA was quantified by real-time PCR. RESULTS: Intrahepatic HBV DNA was detected in 32.4% (23/71) of the entire cohort, and HBV DNA levels were invariably low in the different groups. Occult HBV infection was detected more frequently in the anti-HBc-positive patients. Intrahepatic HBV DNA was detected in 28.1% (9/32) of the anti-HCV-positive and 35.9% (14/39) of the anti-HCV-negative subjects. The HCV genotype did not affect the detection rate of intrahepatic HBV DNA. In anti-HCV-positive cases, occult HBV infection did not affect liver disease severity. CONCLUSIONS: Low levels of intrahepatic HBV DNA were detected frequently in both HBsAg-negative and anti-HCV-positive cases. However, the frequency of occult HBV infection was not affected by the presence of hepatitis C, and occult HBV infection did not have a significant effect on the disease severity of hepatitis C.

A 62-year-old woman was admitted due to acute pain in the back and the right lower extremity. CT and angiography showed a chronic dissection of the ascending aorta and a newly developed dissection of the descending aorta complicated with ischemia of the left renal artery and right lower extremity. Therefore, a Wall stent was inserted percutaneously at the descending thoracic aorta and the stenotic left renal artery was opened by percutaneous transluminal renal angioplasty with a Mac (4.0 x 22 mm, Amg, Korea) stent. Thereafter, renal function was normalized and the blood pressure was better controlled at discharge. A follow up CT scan 3 months after the procedure showed patent true lumen of the descending thoracic aorta and left renal artery.

BACKGROUND/AIMS: The treatment of choice of intraductal papillary mucinous neoplasm (IPMN) is partial pancreatic resection with complete excision of this potentially malignant lesion, thus preserving sufficient pancreatic tissue to ensure endocrine and exocrine functions. This strategy, however, requires a reliable preoperative assessment of the highly variable extension of IPMN. We performed this study to determine the role of intraductal ultrasonography (IDUS) in predicting the extension of IPMN and selecting the resection methods of pancreas. METHODS: A preoperative assessment of IPMN by IDUS was performed in 12 patients who underwent a surgical resection of IPMN. According to the preoperative localization of IPMN by IDUS, various types of limited pancreatic resections were planned. The histologic examination of the frozen section of the pancreatic cut surface was performed in all patient. In the cases of tumor involvement as cut surface margin, a modification of the planned pancreatic resection was done. RESULTS: Technical success was achieved in all 12 cases (100%). There were positive tumor margin of cut surfaces in 2 patients. Of 10 cases whose frozen tissue evaluation of the pancreatic cut surface had been negative at first, one patieat has turned out to be margin positive in permanent section examination, finally. Overall accuracy of IDUS in predicting the continuous extension of IPMN was 75%. CONCLUSIONS: IDUS is a reliable diagnostic modality to guide the resection extent of the pancreas in patients with IPMN.

OBJECTIVES: To determine accurate diagnosis and proper treatment, we reviewed colonoscopic and histologic findings of flat adenoma of colon, METHODS: We studied retrospectively 2148 cases of colonoscopic findings performed in our hospital from March of 1993 to September of 1995. RESULTS: 1) The incidence of adenoma is 9.5%(203 cases), and that of flat adenoma is 1.6%(34 cases). 2) The location of flat adenoma is 3 cases in rectum(8.8%), 15 cases in sigmoid colon(44.1%), 9 cases in descending colon(26.5%), 3 cases in transverse colon(8.8%) and 4 cases in ascending colon and cecum(11.8%). 3) The diameter of flat adenoma was smaller than 5mm in 17 cases(50.0%), between 5-10mm in 8 cases(23.5%) and larger than 10mm in 9 cases (26.5%). Mean size was 9.2mm. 4) In colonoscopic features, type IIa was 25 cases (73.5%), type IIa + IIc was 5 cases(14.7%) and lateral spreading tumor was 4 cases(11.8%). 5) In histologic findings, tubular adenoma was 26 cases(76.5%), tubulovillous adenoma was 6 cases (17.6%) and serrated adenoma was 2 cases(5.9%). 6) The incidence of severe dysplasia or carcinoma was zero in smaller than 5mm, 25.0%(2 case) in 5-10mm and 55.6%(5 cases) in larger than 10mm. 7) The incidence of severe dysplasia or carcinoma was 11.5%(3 cases) in tubular adenoma and 66.7%(6 cases) in tubulovillous adenoma. 8) It was confirmed by abdominal CT scan or operation that lesions were limited to intraepithelium in 4 cases, mucosa in 2 cases submucosa in 1 case and no lymph node metastasis in any case. CONCLUSION: Even though flat adenoma of colon was smaller than polypoid adenoma, the incidence of malignant change was higher. When it was smaller than 10mm, the incidence of submucosal invasion or lymph node invasion was rare. Therefore endoscopic mucosal resection(EMR) can be the treatment of choice in flat adenoma smaller than 10mm, and after EMR, it is desirable to decide the treatment modality depending on the histologic findings.
