PURPOSE To scrutinize retinal involvement associated with distinct mitochondrial DNA (mtDNA) defects, we reviewed the records of a consecutive series of patients with various mitochondrial diseases. METHODS Clinical, laboratory and mtDNA studies were performed in: five patients with Kearns-Sayre syndrome (KSS); six patients with chronic progressive(More)
The relationship between the expression of parathyroid hormone-related protein (PTHrP) by breast cancer and skeletal metastases, was investigated using a monoclonal antibody against human PTHrP (4B3). The immunohistochemical localization of PTHrP was studied in sections of formalin-fixed, paraffin-embedded tissues from 28 breast cancers obtained surgically(More)
Eight pigs were inoculated subcutaneously with a highly virulent hog cholera virus (HCV) strain ALD. The infected pigs developed severe illness and became moribund on postinoculation day (PID) 7 or PID 10. Histologic lesions were characterized by severe generalized vasculitis, necrosis of lymphocytes, and encephalitis. HCV antigen was detected in crypt(More)
A pregnant woman was found to have severe hypertriglyceridemia, fasting chylomicronemia, and low platelet count. The activities of serum lipoprotein lipase (LPL) and hepatic triglyceride lipase (HTGL) proved to be extremely low. The activities of the enzymes in normal plasma were completely inhibited by addition of the patient's plasma. We concluded that(More)
Choriocarcinoma, a malignant tumor of usually placental origin, in divided into two groups; the gestational and non-gestational types, the latter being rare. Non-gestational choriocarcinoma occurs in the lung, mediastinum, kidney, stomach, and small intestine, but rarely appears in the large intestine. We treated a 29-year-old woman with choriocarcinoma of(More)
BACKGROUND Nursing and healthcare-associated pneumonia (NHCAP) is a relatively new condition that was recently defined by the Japanese Respiratory Society. Previous reports and guidelines have not thoroughly investigated the adverse prognostic factors and validity of the selection criteria for NHCAP. The purpose of this research was to clarify the adverse(More)
We report three patients with inferotemporal visual field defect following pars plana vitrectomy for idiopathic macular hole. Two patients complained of the visual field defect early in the postoperative period, and one patient was asymptomatic but showed abnormalities in perimetry. The visual field defect remained unchanged during a follow-up study of 4 to(More)
Although drug-induced interstitial pneumonitis caused by gefitinib is well recognized in Japan, reports of alveolar hemorrhage caused by gefitinib are very rare. We encountered a case of alveolar hemorrhage thought to be caused by gefitinib. A 74-year-old woman with non-small cell lung cancer (adenocarcinoma; cT4NOM0, stage IIIB) had been receiving(More)
Inactivation of the "deleted in colon cancer" (DCC) gene on chromosome 18 is known to be associated with the tumorigenesis and metastasis of colorectal cancer. In the present study, we investigated the expression of DCC and the c-erbB-2 product in surgical specimens from 45 patients with breast cancer by immunohistochemical staining, and found the(More)
