ABSTRACT
<b>Background</b><br> In recent years, inbound tourists to Japan are increasing. Although they rarely suffer diseases or injuries during travels, they may feel anxiety for medical services in foreign countries. This study was aimed to consider how inbound tourists visiting Japan feel about Japanese medical cares.<br><b>Methods</b><br> Inbound tourists who came to the Tokyo Sightseeing Information Center were investigated. The questionnaire composed of 12 items relating to Japanese medical cares and levels was made in three languages; English, Chinese and Korean.<br><b>Results</b><br> A total of 163 tourists including 98 English speakers, 39 Korean speakers and 26 Chinese speakers were enrolled in the study. (1) Native English speakers had a high anxiety about the communication with Japanese medical staffs (p<0.001). (2) Chinese and Korean speakers subjective estimated the Japanese medical level low (p <0.001). (3) Chinese and Korean speakers had a high anxiety for medical costs while traveling (p<0.001). (4) In a case of emergency, English speakers mostly “look for a drugstore and a hospital”, while Chinese and Korean speakers mostly “contact a travel agency and a tour conductor”.<br><b>Conclusion</b><br> Considering foreign tourists' needs vary with their nationality and culture, Medical staffs should support them to have desired medical care in Japan.
ABSTRACT
A 58-year-old man, who was under treatment for urticaria with emedastin fumarate for seven days, was admitted to our hospital because of jaundice. On admission, laboratory data showed the cholestatic type of liver dysfunction, AST 106 U/1, ALT 274 U/1, T-Bil 6.8 mg/dl, γ-GTP 857IU/1, and ALP 807IU/1. Anti-mitochondrial antibody (AMA) was positive with titer of 1: 80, whereas anti-pyruvate dehydrogenase (PDH) antibody was negative. Histologically, mild lymphocytic infiltration in portal area was noted. There was no fibrosis or cholangitis. A lymphocyte stimulation test for emedastin fumarate was positive and the diagnosis of drug-induced liver injury was established. Administration of the drug was immediately withheld followed by an immediate improvement in the most of the liver function tests, whereas both AMA and γ-GTP were constantly abnormal for the following two years. Anti-PDH antibody was still negative. The second biopsy of the liver showed minimal expansion of the portal area with fibrosis and mild lymphocytic infiltration. Pseudo-ductular formation and vanished bile ducts were also confirmed although no granulomas were found. These findings were atypical for primary biliary cirrhosis. This seems to be a rare case of drug-induced liver injury with long-standing anti-mitochondrial antibody without primary biliary cirrhosis as an underlying disease.
ABSTRACT
The liver mitochondrial redox state (the liver mitochondrial free NAD+/NADH ratio), which indicates hepatic energy charge, is known to parallel the ketone body ratio (acetoacetate/3-hydroxybutyrate) in liver tissue. Since the ketone body ratio in arterial blood was reported to correlate with that in liver tissue; the arterial ketone body ratio (AKBR) has been widely accepted as a useful measure of the liver function reserve. The liver mitochondrial redox state is known to decrease with the oxidation of ethanol in alcohol abusers. To evaluate whether AKBR reflected the effect of alcohol intake on the liver, AKBR was measured in normal controls (n=8), and patients with alcoholic liver injuries (n=14) and chronic active hepatitis (n=15). The mean AKBRs in the normal control subjects, in patients with chronic active viral hepatitis, and in those with alcoholic liver disease were 1.68±0.77, 2.22±1.02, and 1.55±0.79, respectively. Though the AKBR in patients with alcoholic liver disease tended to be lower than the other groups, there was no significant difference in AKBR among those three groups. In conclusion, this study demonstrated that AKBR was doubtful as an accurate parameter to estimate the changes in the liver mitochondrial redox state by alcoholic intake.
