We used texture analysis with the co-occurrence matrix method to analyze ultrasonograms from normal and diseased livers, and X-ray CT images obtained from normal cases and cases of idiopathic interstitial pneumonia. Ten cases of normal, fatty, and cirrhotic livers; 10 cases of normal lungs; and 10 cases of idiopathic interstitial pneumonia, all confirmed by(More)
A 75-year old woman was referred to our hospital due to a worsening post-operative cutaneous ulcer. She had a history of polycythemia vera and had been treated with a daily dose of 500mg hydroxyurea (HU) for six years. She underwent a right hernioplasty in another hospital in September 2002.

Case 1, Borrmann's type 2 carcinoma detected by endoscopy in the body of the stomach of a 59-year-old man. Total gastrectomy with spenectomy was performed. Histologic examination revealed a poorly differentiated adenocarcinoma with marked venous invasion. Follow-up ultrasonography showed the tumor thormbi in the splenic vein to be progressively distended to(More)
We report a 54-year-old Japanese man who contracted severe falciparum malaria after visiting West African countries. The patient presented with Plasmodium falciparum parasitemia of 10% on admission and was successfully treated with intravenous artesunate combined with continuous hemodiafiltration. We found that intravenous artesunate had excellent(More)
We used a real-time, ultrasound scanner to establish a reference interval of liver size in children based on their height and age. The study group comprised 476 children ranging in age from 1 month to 15 years. Maximal craniocaudal length (L1) and anteroposterior width (L2) determined in the longitudinal plane passing through the aorta were used as(More)
We ultrasonographically measured renal length in the major axis in children. Here we discuss the differences in measured lengths in the supine and prone positions. In study 1, which included 214 children, more than 60 percent of the kidneys measured longer in the supine than in the prone position. The difference (S-P: length in the supine position minus(More)
A 47-year-old Chinese woman with no significant medical history admitted for sudden-onset seizures and transient right homonymous hemianopsia had moved from China to Japan 4 years previously. Contrast brain computed tomography (CT) showed multiple calcified nodular lesions with surrounding edema, one in the left parietal lobe being likely responsible for(More)
A 13-year-old girl was admitted to the hospital because of cardiomegaly found incidentally at regular medical checkup at her school. Although dilated cardiomyopathy was suspected, the girl showed no symptoms. chest x-ray film showed cardiomegaly (cardiothoracic ratio, 67%), and echocardiogram demonstrated a dilatation of the left ventricle without thinning(More)
