In our study population, 21.8% had fatty liver diagnosed by USG, 9.3% were non-alcoholic with fatty liver, and 4.1% were non-alcoholic and non-overweight with fatty liver. Our results suggest that central body fat distribution can correlate with the development of fatty liver, and that measurement of percentage body fat is useful to assess the etiology of fatty liver in non-alcoholic and non-overweight participants, particularly women.

The SLiDe scoring system is useful for the assessment of the prognosis of patients with HCC as long as the Japanese staging system is used, although this uses parameters such as the indocyanine green retention test and DCP, which are not examined routinely in every part of the world. Therefore, the proposed classification should be further validated in other large study populations.

Extraintestinal manifestations of ulcerative colitis (UC) are well known, but immunologically mediated hematological diseases are relatively rare. We describe two cases of immune thrombocytopenic purpura (ITP) associated with preexisting UC. Our patients had typical symptoms of UC, and endoscopy showed pancolitis. During treatment with 5-aminosalicylic acid and steroids, severe thrombocytopenia was noted. ITP was diagnosed based on a normal to high number of megakaryocytes in the bone marrow, positive autoantibody to platelet membrane antigen, and absence of splenomegaly. Medical treatment, including increased dosage of steroids, failed to control UC and ITP in both patients. In the first patient, the platelet count recovered after colectomy, while the second patient died of a cerebral hemorrhage. We stress that a diagnosis of ITP should be considered for thrombocytopenia in patients with UC, especially those showing extensive and significant colonic inflammation, and that colectomy of UC might resolve resistant ITP.

AbstrctThe mechanism of maternal mitochondrial inheritance in animals involves the selective elimination of sperm mitochondria by the elimination factor of the egg and the sperm mitochondria-specific factor. In vitro fertilization using sperm from congenic mice incorporating heterogeneous mitochondrial DNA (mtDNA) showed that the number of PCR positives of sperm mtDNA in two-cell embryos was significantly increased following sperm incubation with anti-tpis, anti-Tom22 and anti-Tom40 antibodies. The treatment of fertilized eggs with EGTA and endonuclease inhibitors increased the sperm mtDNA levels. We conclude that the elimination factor, which is probably an endonuclease, is selectively received by the tpis protein of the sperm mitochondrial outer membrane within the egg. It is then transported into the sperm mitochondria by Tom22 and Tom40, where it destroys the sperm mtDNA, establishing the maternal inheritance of mtDNA.3

The true incidence of hepatocellular carcinoma (HCC) in patients with primary biliary cirrhosis (PBC) remains undetermined due to limited epidemiological studies and some conflicting results. Some studies indicated that in PBC, male gender, cirrhosis, hepatitis C virus (

A 24-year-old-woman was admitted to our hospital for further examination of recurrent upper gastrointestinal tract hemorrhage. The characteristic xanthomatous papular rash, retinal angioid streaks, and stenosis of cardiac coronary artery confirmed the diagnosis of pseudoxanthoma elasticum. Upper gastrointestinal endoscopy revealed vascular dilation in the gastric body to fornix. The vessel showing conspicuous dilation covered with the discolored mucosa was suspected as the source of the bleeding. The vessel was identified as a dilated vein located in the submucosa by endoscopic ultrasonography and pulsed-wave Doppler ultrasonography. Abdominal angiography demonstrated aneurysmal dilation in the splenic artery, but not in the gastric artery. Endoscopic band ligation was chosen as an initial treatment for the prevention of recurrent bleeding. The procedure seemed to be successful, but rebleeding occurred on the next day, which was again treated with hemostatic clipping. There have been no further episodes of gastrointestinal hemorrhage during the 15-month follow up.
