Bilateral Serous Retinal Detachment in Lymphoid Blast Crisis of Chronic Myeloid Leukemia.

We herein report a patient with Philadelphia chromosome-positive lymphoid blast crisis of chronic myeloid leukemia (CML), who presented with bilateral serous retinal detachment (SRD). A 36-year-old Asian male presented with the symptoms of decreased vision and was found to have bilateral SRD involving fovea. There was no inflammation in the anterior chamber or vitreous.

Impact of low luminance conditions on quality of life for the visually impaired: development of the Low Luminance Questionnaire Japanese version.

Purpose: This study aimed to develop a Japanese version of the Low Luminance Questionnaire (LLQ-J) and to evaluate its reliability and validity.

Study Design: Cross-sectional study.

Methods: LLQ-J was developed by standardized methods.

Syndecan-1 Promotes Streptococcus pneumoniae Corneal Infection by Facilitating the Assembly of Adhesive Fibronectin Fibrils.

Subversion of heparan sulfate proteoglycans (HSPGs) is thought to be a common virulence mechanism shared by many microbial pathogens. The prevailing assumption is that pathogens co-opt HSPGs as cell surface attachment receptors or as inhibitors of innate host defense. However, there are few data that clearly support this idea We found that deletion of syndecan-1 (Sdc1), a major cell surface HSPG of epithelial cells, causes a gain of function in a mouse model of scarified corneal infection, where corneas were significantly less susceptible to infection.

Unusual Case of Vogt-Koyanagi-Harada Disease Associated with SAPHO Syndrome: A Case Report.

A 66-year-old Japanese woman who was diagnosed with synovitis-acne-pustulosis-hyperostosis-osteitis (SAPHO) syndrome presented with bilateral blurred vision 4 months prior to visiting our hospital. She had visited a local ophthalmology clinic first. She was diagnosed with conjunctivitis and was prescribed antibacterial eye drops.

Increased expression of interleukin-6 predicts poor response to chemoradiotherapy and unfavorable prognosis in oral squamous cell carcinoma.

Recent studies have revealed that cancer cells are exacerbated by chronic inflammation. The present study examined the immunohistochemical expression for interleukin-6 (IL-6), a pleiotropic inflammatory cytokine, in oral squamous cell carcinoma (OSCC) to elucidate the association of IL-6 expression with tumor progression, chemoresistance and prognosis. Seventy-eight patients with primary OSCC were analyzed by immunohistochemical staining for IL-6.

Thymosin beta 4 is associated with RUNX2 expression through the Smad and Akt signaling pathways in mouse dental epithelial cells.

In previous studies by our group, we reported that thymosin beta 4 (Tb4) is closely associated with the initiation and development of the tooth germ, and can induce the expression of runt-related transcription factor 2 (RUNX2) during the development of the tooth germ. RUNX2 regulates the expression of odontogenesis-related genes, such as amelogenin, X-linked (Amelx), ameloblastin (Ambn) and enamelin (Enam), as well as the differentiation of osteoblasts during bone formation. However, the mechanisms through which Tb4 induces the expression of RUNX2 remain unknown.

Role of glycosaminoglycans in infectious disease.

Glycosaminoglycans (GAGs) have been shown to bind to a wide variety of microbial pathogens, including viruses, bacteria, parasites, and fungi in vitro. GAGs are thought to promote pathogenesis by facilitating pathogen attachment, invasion, or evasion of host defense mechanisms. However, the role of GAGs in infectious disease has not been extensively studied in vivo and therefore their pathophysiological significance and functions are largely unknown.

[Mucoepidermoid carcinoma of the intrahepatic bile duct with metastasis to the cranial skin].

Mucoepidermoid carcinoma of the intrahepatic bile duct is a rare variant of cholangiocarcinoma: it is composed of mucus-secreting squamous cells and glandular cells within the same nests. This tumor is very aggressive, with high-grade malignancy, and has a poor prognosis. In the international literature, only 17 cases of mucoepidermoid carcinoma originating in the hepatic bile duct system have been reported until now.

[Marked effect of combination chemotherapy with tegafur-gimeracil-oteracil potassium and gemcitabine on a suspected case of pancreas cancer or gallbladder cancer metastasis to bone: further diagnosis of disseminated carcinomatosa of bone marrow recurrence after the 23 years of gastric cancer operation by autopsy findings].

A 70-year-old woman who underwent proximal gastrectomy for gastric cancer (poorly-differentiated adenocarcinoma) of Stage IIIB at age 46 visited our hospital April 2004 because of exacerbated pain by movement in the buttocks since November 2003. She showed multiple bone metastasis by CT (computerized tomography). Pancreas cancer or gallbladder cancer was suspected by CT, and a high tumor marker score (CA19-9 18,625 U/mL, DUPAN-II 15,000 U/ mL elevations were acknowledged).
