Neurocognitive function differentiation from the effect of psychopathologic symptoms in the disability evaluation of patients with mild traumatic brain injury.

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.

Endoscopic evaluation in gastrointestinal graft-versus-host disease: comparisons with histological findings.

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.

[A case of transmesocolic hernia in elderly person without a history of operation].

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 case of hepatoid carcinoma of the pancreas].

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.

[A case of acute hepatitis E with the travel history to an endemic area].

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%.
