Early onset cerebellar ataxia with retained tendon reflexes is clinical syndrome characterized by progressive cerebelar ataxia of unknown etiology with an onset within the first two decades. This disorder was distinguished from Friedreich's ataxia by the preservation of the tendon reflexes. We have experienced a case of early onset cerebellar ataxia with retained tendon reflexes which was diagnosed by clinical features, eletrophysiologic studies, and MRI scan. This 8 year-old male patient had suffered from gait ataxia with delayed growth and development since 3 years of age. A brief review of the related literatures was also made.

PURPOSE: Spontaneous hemoperitoneum is not a common disease but may cause a fatal outcome. Warfarin is a coumarin anticoagulant, used widely for therapeutic and prophylactic anticoagulation. Although, it is considered a life saving medicine, it is associated with significant adverse effects including intraabdominal bleeding. Literatures about spontaneous hemoperitoneum in patients taking anticoagulants have been reported, but until now there have not been a definite establishment in diagnostic criteria and treatment strategy. METHODS: Among 209 patients who were diagnosed hemoperitoneum from Jan 2005 through May 2009, we identified 9 patients with spontaneous hemoperitoneum without any trauma history or solid organ abnormalities. All 9 patients were taking warfarin for various durations. Initially, we evaluated vital signs, laboratory, CT findings, and clinical course, retrospectively. In addition, we analyzed risk factors potentiating the pharmacologic effect of anticoagulants. RESULTS: One of the most prominent features in this study is that all patients showed prolonged international normalized ratio (6.36~15.11). One patient received an exploratory laparotomy for hemoperitoneum secondary to warfarin, presenting as a localized peritonitis in the right lower quadrant of the abdomen. Mean hospital stay was 15.2 days. Five patients were transfused with packed red blood cells (500~1,000 ml) and fresh frozen plasma (300~900 ml). All patients were discharged without any mortality. CONCLUSION: It is important to identify and confirm the factors that can potentiate the pharmacologic effect of anticoagulants, when acute abdomen is suspected in patients taking anticoagulants. If the patients are hemodynamically stable, they can be treated without surgical intervention.

PURPOSE: The 12-lead ECG in the emergency department is at the hub of the therapeutic decision pathway because ST-segment elevation identifies patients who most benefit from reperfusion therapy. The optimal definition of ST elevation for diagnosis of anterior wall ST elevation myocardial infarction (STEMI), with respect to the measuring point or the amplitude is unknown. METHODS: One hundred six consecutive patients with acute myocardial infarction who visited our emergency medical center from August 2005 to June 2007 were prospectively recruited. Patients with atrial flutter/fibrillation, bundle brach block, left ventricular hypertrophy, preexcitation, ventricular aneurysm, or paced rhythm were excluded. ST segment was measured at the J point, 40 ms after the J point, 80 ms after the J point, and relative to the PR segment, in all six precordial leads. The diagnostic accuracy of ST segment measuring point and amplitude were assessed by receiver operating characteristic (ROC) curve analysis. RESULTS: Mean ST segment amplitude in all precordial leads was lowest when measured at the J point, and highest when measured at 80 ms after the J point. ST segment measured at 40 ms after the J point had the highest predictive value for diagnosing anterior STEMI (p=0.01). The optimal cutoff value for precordial leads ST segment amplitude was greater than 2 mm in leads V2, and V3 and greater than 1 mm in other precordial leads. Using these cutoff values, leads V2-V4 were more accurate than the other precordial leads. With, sensitivities of 82%, 90%, and 82%, respectively, and specificities of 80%, 85%, and 78%. The areas under the ROC curve for leads V2-V4 were 0.90 (95% CI: 0.83-0.96), 0.93 (95% CI: 0.88-0.98), and 0.88 (95% CI: 0.82-0.94). CONCLUSION: Different measurements of the ST segment result in variations in the sensitivity and specificity of diagnosis of anterior STEMI. This new criteria for ST segment elevation is crucial for identifying patients eligible for emergency reperfusion therapy.

BACKGROUND: Presenteeism, a concept that has recently undergone active study, is the act of attending work while sick. This study investigates the association between presenteeism and various psychosocial factors within workplaces. METHODS: This study analyzed 29246 wage earners from the third Korean Working Conditions Survey (KWCS, 2011) data using the logistic regression analysis to investigate the association between presenteeism and various psychosocial factors within workplaces. RESULTS: Among the 29246 wage earners, 6347 (21.7 %) showed presenteeism. Those who experienced age discrimination at work (adjusted odds ratio (aOR) 1.77: 95 % CI 1.56–2.00), educational background discrimination (aOR 1.35: 95 % CI 1.22–1.51), regional discrimination (aOR 1.55: 95 % CI 1.31–1.83), sexual discrimination (aOR 1.65: 95 % CI 1.41–1.94), employment type discrimination (aOR 2.13: 95 % CI 1.89–2.40), physical violence (aOR 1.92: 95 % CI 1.45–2.55), sexual harassment (aOR 2.90: 95 % CI 2.01–4.19), job insecurity (aOR 1.36: 95 % CI 1.18–1.56), work–life imbalance (aOR 1.38: 95 % CI 1.29–1.47), low job satisfaction (aOR 2.04: 95 % CI 1.91–2.17), no colleague support (aOR 1.11: 95 % CI 1.02–1.21), job stress (aOR 1.89: 95 % CI 1.76–2.02), emotional labor (aOR 1.50: 95 % CI 1.41–1.60), high work intensity (aOR 1.31: 95 % CI 1.23–1.38), and 3 groups of job strain that are passive group (aOR 1.09: 95 % CI 1.00–1.18), active group (aOR 1.39: 95 % CI 1.28–1.51), and high strain group (aOR 1.35: 95 % CI 1.24–1.46) showed an increased risk of presenteeism compared to their respective counterparts (p < 0.01). CONCLUSIONS: The study results confirmed the association between presenteeism and various psychosocial factors within workplaces. Considering that presenteeism negatively affects productivity and the mental and physical health of individuals, managing various psychosocial factors within workplaces is proposed to reduce presenteeism.

Gastritis cystica profunda (GCP) is a rare disease which is mainly observed at the site of gastroenterostomy. However, it may occur in the stomach without a previous history of surgery. Under histologic examination GCP shows hyperplastic and cystic dilatation of the pseudopyloric glands with submucosal invasion. GCP with sessile polypoid pro-trusion is most commonly found but, submucosal tumors, giant gastric mucosal folds and pedunculated forms are occasionally found. We present the case of GCP showing a large sized polyp (3 2.5 2.5 cm) with a long pendulous pedicle that had developed in the fundus of the stomach without previous surgical history. Endoscopic polypectomy was performed for confirmation.

PURPOSE: The effects of hepatic resection on patients with metastatic tumors from gastric adenocarcinomas are unclear. Therefore, we analyzed early clinical outcomes in patients who underwent surgical resection for hepatic metastases from gastric adenocarcinomas. MATERIALS AND METHODS: From January 2003 to December 2010, 1,508 patients with primary gastric cancers underwent curative gastric resections at the Korea Cancer Center Hospital. Of these patients, 12 with liver-only metastases underwent curative hepatic resection. Their clinical data were analyzed retrospectively. RESULTS: The median follow-up period was 12.5 months (range, 1~85 months); no operative mortalities or major complications were observed. Three patients underwent synchronous resections, and 9 underwent metachronous resections. In the latter group, the median interval between gastrectomy and hepatectomy for hepatic metastasis was 10.5 months (range, 5~47 months). The overall 1- and 5-year survival rates of these 12 patients were 65% and 39%, respectively, with a median overall survival of 31.0 months; 2 patients survived for >5 years. CONCLUSIONS: Hepatic resection can be a feasible procedure for treating hepatic metastases from gastric adenocarcinomas. Although this study was small and involved only selected cases, the outcomes of the hepatic resections were comparable and long-term (>5 years) survivors were identified. Surgical resection of the liver can be considered a feasible option in managing hepatic metastases from gastric adenocarcinomas.

Background/Aims: The optimal treatment for acute malignant obstruction of the proximal colon (MOPC, proximal to the splenic flexure) remains challenging. Emergency resection, the traditional modality for MOPC, has shown significantly high mortality and morbidity rates, according to recent studies. This study aimed to investigate the clinical outcomes of stent vs stoma as a bridge to curative surgery for MOPC. Methods: This retrospective cohort study included 72 patients who underwent endoscopic placement of a self-expanding metallic stent (SEMS) or loop ileostomy for MOPC at six referral centers between January 2011 and July 2021. Clinical and pathological characteristics, procedure-related complications, and long-term mortality rates after curative surgery were analyzed. Results: During a mean follow-up period of 32 months, 30 patients (41.7%) underwent ileostomy preferentially for more proximal cancer, complete obstruction, and advanced tumor stage compared to the SEMS group. No difference was found in procedure-related complications, but five deaths were observed after ileostomy. Survival analysis for 5-year mortality after curative surgery showed no significant difference between the bridge modalities (log-rank p = 0.253). Conclusions In this study, SEMS as a bridge to surgery showed relatively safe results in terms of post-procedural mortality. However, these results should be considered when performing ileostomy in patients with more advanced malignant obstruction.

BACKGROUND/AIMS: The aim of this study was to investigate the immunohistochemical expression of bcl-2, bcl-xL, bax, and p53 proteins according to the pathological parameters such as grade of dysplasia, histological type, depth of invasion, lymph node metastasis, and TNM stage in the gastric adenoma and gastric adenocarcinoma. METHODS: Immunohistochemical staining using monoclonal bcl-2, bcl-xL, bax, p53 antibodies were performed on paraffin embedded specimens from forty-one gastric adenomas and 100 gastric adenocarcinomas. RESULTS: The expression rate of bcl-2 was higher in adenomas (34.2%), especially in high grade dysplasia (52.4%), than adenocarcinomas (2.0%). The expression rate of bcl-xL was higher in adenocarcinomas (55.0%) than adenomas (22%). The expression rate of the bax was higher in adenocarcinomas (58.0%) than adenomas (14.6%). In the adenocarcinoma, the bax expression was significantly related with the depth of invasion, lymph node metastasis, and TNM stage. The expression rate of p53 was higher in adenocarcinomas (64.0%) than adenomas (14.6%). CONCLUSIONS: Bcl-2 protein would be related with the development of gastric adenoma, especially with high grade dysplasia. Bcl-xL and p53 proteins would be involved in the development of relatively early stage of gastric adenocarcinoma but not in tumor progression. Bax protein would be involved in the development of gastric adenocarcinoma and related with depth of invasion, lymph node metastasis, and TNM stage.
