RESUMO
OBJECTIVE: We determined whether the relationship between the neuropsychological performance of patients with mild traumatic brain injury (TBI) and their psychopathological characteristics measured by disability evaluation are interrelated. In addition, we assessed which psychopathological variable was most influential on neuropsychological performance via statistical clustering of the same characteristics of mild TBI. METHODS: A total of 219 disability evaluation participants with mild brain injury were selected. All participants were classified into three groups, based on their psychopathological characteristics, via a two-step cluster analysis using validity and clinical scales from the Minnesota Multiphasic Personality Inventory (MMPI) and Symptom Checklist-90-revised (SCL-90-R). The Korean Wechsler Adult Intelligence Scale (K-WAIS), Korean Memory Assessment Scale (K-MAS) and the Korean Boston Naming Test (K-BNT) were used to evaluate the neurocognitive functions of mild TBI patients. RESULTS: Over a quarter (26.9%) experienced severe psychopathological symptoms and 43.4% experienced mild or moderate psychopathological symptoms, and all of the mild TBI patients showed a significant relationship between neurocognitive functions and subjective and/or objective psychopathic symptoms, but the degree of this relationship was moderate. Variances of neurocognitive function were explained by neurotic and psychotic symptoms, but the role of these factors were different to each other and participants did not show intelligence and other cognitive domain decrement except for global memory abilities compared to the non-psychopathology group. CONCLUSION: Certain patients with mild TBI showed psychopathological symptoms, but these were not directly related to cognitive decrement. Psychopathology and cognitive decrement are discrete aspects in patients with mild TBI. Furthermore, the neurotic symptoms of mild TBI patients made positive complements to decrements or impairments of neurocognitive functions, but the psychotic symptoms had a negative effect on neurocognitive functions.
RESUMO
The gastrointestinal (GI) tract is the major target site of the graft-versus-host disease (GVHD). Whether endoscopic findings can predict the histological diagnosis and degree of severity in GVHD remains controversial. We investigated the degree of correlation between endoscopic and histological findings, and evaluated the impact of endoscopic examination on clinical decision in GVHD management. This study was conducted as a retrospective single-center study. One hundred and one patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) and at the risk of GI GVHD were referred for endoscopic evaluation. Endoscopic images and histology were reviewed to diagnose and grade in a blind fashion, and the histological findings were used as the "gold standard" for diagnosis. Endoscopic findings revealed a significantly positive association with histological abnormalities of GVHD (odds ratio [OR] = 33.6, 95% CI 4.3-261.1), and the sensitivity and specificity were 98 and 44%, respectively. The kappa coefficient for agreement between the endoscopic and histological grading was 0.423 (p-value < 0.001). Ten (18%) patients out of 57 histology-negative cases were managed successfully as GVHD on the endoscopic finding. Though the overall reliability of endoscopic diagnosis in GVHD is still insufficient in terms of sensitivity and specificity, high-grade cases such as grades 3 or 4 showed specific endoscopic findings to draw a significant agreement with histological findings. Endoscopic examination can give critical information and impose a pivotal impact on clinical decision when the histology is discordant with clinical presentation.

Internal hernia is defined as the herniation of viscera through an anatomic or pathologic opening within the boundaries of peritoneal cavity. Transmesocolic hernia, a subtype of internal hernia, has a herniated sac through the transverse mesocolon. Transmesocolic hernia has been rarely described in the literature, and most of reported cases were associated with a history of operation or congenital anormaly. A 72-year-old female with chronic intermittent abdominal pain and bloating was admitted. Small bowel series showed multiple jejunal loops confined to the left upper quadrant of abdomen. Abdomen spiral computed tomography (CT) showed a cluster of mildly dilated small bowel loops with mesenteries on the same area. On the three-dimensional reconstruction CT scan, a herniated sac through the transverse mesocolon was identified. She was diagnosed as transmesocolic hernia by using the three-dimensional reconstruction CT and small bowel series, without surgical exploration. The symptoms were managed with conservative measures.

Hepatoid carcinoma is a primary extrahepatic neoplasm exhibiting features of hepatocellular carcinoma (HCC) in terms of morphology, immunohistochemistry, and behavior. In many cases, tumor cytoplasm is positive for alpha- fetoprotein (alpha-FP) with elevated serum alpha-FP level. Because not all hepatoid carcinomas are associated with alpha- FP overproduction, diagnosis should be made essentially by histological features of the tumor. We present a case of hepatoid carcinoma of the pancreas in a 21-year-old male patient. Abdominal computed tomography and magnetic resonance imaging revealed an inhomogeneously enhanced pancreatic head mass. Serum alpha-FP level was markedly elevated. He underwent pylorus-preserving Whipple's operation. The tumor showed hepatoid and neuroendocrine components simultaneously. The histopathological diagnosis was hepatoid carcinoma associated with neuroendocrine tumor of the pancreas. Seven months after the surgery, the patient is healthy without evidence of recurrence. To date, only 7 cases of hepatoid carcinoma of the pancreas have been reported in the literature, and this is the first case report in Korea.

Hepatitis E is a self-limited and enterically transmitted acute viral hepatitis that occurs from epidemic outbreaks of developing countries and sporadic hepatitis in non-endemic areas. In endemic areas, hepatitis E virus (HEV) is one of the most common causes of acute hepatitis and hepatic failure in pregnancy. Its mortality rate has been reported up to 20%. In non-endemic areas, HEV infection without any travel history is very rare. In Korea, only one case of simple hepatitis E without any travel history to endemic areas was reported. Recently, we experienced a case of acute hepatitis. The patient who had a travel history to India, showed watery diarrhea and high fever. Transaminase level and total bilirubin were increased, and prothrombin time was prolonged. It was positive for IgM anti-HEV and IgG anti-HEV, and showed no evidence of other viral infections or drug ingestion history. In spite of absence of useful test such as seroconversion of IgM anti-HEV and HEV RNA PCR, we diagnosed the case as an acute hepatitis E from his symptom, travel history and initial serologic marker. We report this as a case of hepatitis E infected from endemic areas.
