BACKGROUND Antiphospholipid antibodies (AA) are immunoglobulins that cross-react with phospholipid on cell membrane, and are therefore associated with a hypercoagulable state manifested by arterial/venous thromboses. We aimed to determine the prevalence of deep venous thrombosis in the lower limbs and the pelvic region (DVT) and pulmonary embolism (PE) in(More)
AIM To assess the usefulness of SPECT images using (99m)Tc-Technegas (Technegas) and (133)Xe dynamic single photon emission computed tomography (SPECT) (Xe gas) and high-resolution computed tomography (HRCT), as compared with pathological assessment in the detection of small-airway disease including pulmonary emphysema. METHODS Seventeen patients with(More)
Among galectin family members, galectin-9 was first described as a potent eosinophil chemoattractant derived from Ag-stimulated T cells. In the present study a role of galectin-9 in the interaction between eosinophils and fibroblasts was investigated using a human lung fibroblast cell line, HFL-1. RT-PCR, real-time PCR, and Western blot analyses revealed(More)
Occult breast cancer presenting with axillary lymph node metastases is uncommon, and inflammatory breast cancer (IBC), as a subtype, is quite rare. Here we describe a case of IBC, which arose as an unknown primary carcinoma; the patient presented with axillary lymph node metastasis, and was successfully treated with trastuzumab and vinorelbine.(More)
Simple and accurate diagnosis of vertical transmission of human parvovirus B19 (B19V) infection remains an important issue in pregnancy. There are few reports on quantitative analysis of B19V in amniotic fluids. Quantitative estimation of B19V DNA in amniotic fluids was comparerd with those in maternal or fetal serum obtained at an early stage of pregnancy(More)
Pyothorax-associated lymphoma (PAL) is a non-Hodgkin's lymphoma developing in the pleural cavity after a long-standing history of chronic pyothorax (CP). F-18 fluorodeoxyglucose positron emission tomography (FDG-PET) imaging is a useful modality for determination of disease extent of various malignant tumors, including malignant lymphoma, but there have(More)
The clinical efficacy and safety of hyperfractionated radiotherapy with concurrent chemotherapy were studied retrospectively in patients with primary advanced esophageal cancer. The subjects were 31 patients who were treated with hyperfractionated radiotherapy and concurrent chemotherapy in our institution between 1990 and 2001. The chemoradiotherapy(More)
We describe severe acute transverse myelitis in a previously healthy 9-year-old boy in whom primary human parvovirus B19 infection was confirmed serologically and B19 DNA was detected in his serum and cerebrospinal fluid. Besides erythema infectiosum, parvovirus B19 infection has various clinical manifestations; however, central nervous system involvement(More)
Three-dimensional fast asymmetric spin echo (3D FASE) cisternography provides high spatial resolution and excellent contrast as a water image acquisition technique. It is also useful for the evaluation of various anatomical regions. This study investigated the usefulness and limitations of virtual endoscopic images obtained by 3D FASE MR cisternography in(More)
