PURPOSE. To evaluate the prevalence and range of iridotrabecular contact (ITC) in eyes with a shallow peripheral anterior chamber (AC) by using anterior segment swept-source optical coherence tomography (AS-SS-OCT) and to compare the results with those obtained with ultrasound biomicroscopy (UBM) and gonioscopy. METHODS. Forty-three shallow peripheral AC eyes in 43 consecutive patients underwent gonioscopy. Cross-sectional images throughout the angle circumference (i.e., 360°) were obtained with AS-SS-OCT (SS-1000 noncontact, noninvasive three-dimensional imaging system) and those of the peripheral AC at the 3, 6, 9, and 12 o'clock positions were obtained with UBM (UD-1000). RESULTS. ITC evaluated with AS-SS-OCT included all gonioscopically identified peripheral anterior synechia (PAS) in the area. With AS-SS-OCT, at least one ITC was found in 40 (93.0%) and 42 (97.7%) of the 43 eyes under light and dark conditions, respectively, whereas with UBM, at least one ITC was found in 22 (51.1%) and 36 (83.7%) of the 43 eyes under light and dark conditions. The prevalence of ITC in eyes with AS-SS-OCT was significantly higher than that with UBM under light conditions, but not under dark conditions (P = 0.0001, 0.07, respectively, sign test). The PAS-positive eyes had a significantly greater ITC range than the PAS-negative eyes under light conditions (P = 0.006), but not under dark conditions (P = 0.08). CONCLUSIONS. AS-SS-OCT detected all PAS and the prevalence of ITC detected by AS-SS-OCT in narrow angle eyes was markedly higher than previously thought. A relationship between the ITC range under light conditions and future PAS formation was suggested. © 2013 The Association for Research in Vision and Ophthalmology, Inc. Source

We examined the direct effects of IFN-α on the development of Th17 with a system using immobilized anti-CD3, which permits activation of CD4+ T cells in the complete absence of accessory cells. Highly purified CD4+ T cells obtained from healthy donors were stimulated with immobilized anti-CD3 with or without IFN-α. IFN-α suppressed the production of IL-17 of immobilized anti-CD3-stimulated CD4+ T cells in a dose-response manner. Accordingly, IFN-α inhibited IL-17 mRNA expression in immobilized anti-CD3-stimulated CD4+ T cells. IFN-α did not affect the production of TGF-β or IL-6, but inhibited RORC mRNA expression of anti-CD3-stimulated CD4+ T cells. These results indicate that IFN-α suppresses IL-17 expression and Th17 differentiation through down-regulation of RORC mRNA expression. It is therefore suggested that these effects might play a role in the mode of action of IFN-α in the treatment of various inflammatory diseases. © 2009 Elsevier Inc. All rights reserved. Source

Dietary intake affects hypertension and metabolic syndrome (MS) and their management. In Japanese hypertensive patients, little evidence exists regarding the relation between diet and MS. A self-administered lifestyle questionnaire was completed by each patient at the baseline. Three dietary scores were calculated for each patient: sodium intake, potassium intake and soybean/fish intake. The relationships between dietary scores and systolic blood pressure (SBP) and diastolic blood pressure (DBP) were analyzed by multiple regression analysis. The relation between dietary intake of sodium, potassium and soybean/fish, and the presence of MS was evaluated by the Mantel-Haenszel test. A total of 9585 hypertensive patients (mean age, 64.9 years; women, 51.4%) were included in this sub-analysis. High sodium intake was significantly related to increased SBP (P0.0003) and DBP (P0.0130). Low potassium intake was significantly related to increased SBP (P0.0057) and DBP (P0.0005). Low soybean/fish intake was significantly related to increased SBP (P0.0133). A significantly higher prevalence of MS was found in men in the highest quartile of sodium intake compared with the lower quartiles (P0.0026) and in women in the lowest quartile of potassium intake compared with the higher quartiles (P0.0038). A clear relation between dietary habits and blood pressure was found in Japanese hypertensive patients using a patient-administered questionnaire. Sodium and potassium intake affect MS prevalence. Dietary changes are warranted within hypertension treatment strategies. © 2011 The Japanese Society of Hypertension All rights reserved. Source

A 58-year-old man was found to have an abnormal shadow on chest computed tomography (CT). The size and density of the nodule increased gradually over 7 years. Partial lung resection was performed by a thoracoscopic procedure. The pathological examination and gene analysis revealed that the tumor was primary pulmonary B-cell lymphoma of mucosa associated lymphoid tissue (MALT lymphoma). The CT findings showed that the level of substantial shadow with air bronchograms gradually increased in the center of the mass shadow, while a radial filamentous and ground glass shadow increased in the periphery. The pathological findings showed a cellular lymphocytic infiltrate that had expanded without destroying the existing blood vessels and bronchi in the center area of the tumor, while had expanded in the interstitial area along with vessel bundles in the border area. The CT findings were consistent with the pathological findings. Source

Background: Generalized pustular psoriasis (GPP) is a chronic autoimmune disease characterized by fever, erythema, and neutrophilic pustules over large areas of the skin. GPP does not respond well to pharmacologic intervention. Objective: We sought to assess efficacy of selectively depleting the myeloid lineage leukocytes in patients with GPP. Methods: Fifteen patients with persistent moderate to severe GPP despite conventional therapy were included. Eligible patients had more than 10% of their skin area covered by pustules. Treatment with oral etretinate, cyclosporine, methotrexate, prednisolone, and topical prednisolone/vitamin D3 was continued if had been initiated well in advance of study entry. Five sessions of adsorptive granulocyte and monocyte apheresis (GMA) with the Adacolumn (JIMRO Co Ltd, Takasaki, Japan) were administered (1 session/wk over 5 weeks) to selectively deplete Fcγ receptor and complement receptor bearing leukocytes. Efficacy was assessed by measuring the skin areas covered by pustules at baseline and 2 weeks after the last GMA session. Results: One patient did not complete the first GMA session. Based on the GPP severity scores relative to entry, the overall scores improved (n = 14, P =.0027), and the area of erythroderma (P =.0042), pustules (P =.0031), and edema (P =.0014) decreased. Likewise, Dermatology Life Quality Index improved (P =.0016), reflecting better daily function and quality of life. Twelve patients were judged as responders (85.7%), and 10 patients maintained the clinical response for 10 weeks after the last GMA session without any change in medication. Limitations: This study was unblinded and without a placebo arm. Conclusion: GMA in this clinical setting was safe and effective, suggested a major role for granulocytes/monocytes in the immunopathogenesis of GPP. © 2012 by the American Academy of Dermatology, Inc.
