A boy in his late teens had undergone proctocolectomy for refractory ulcerative colitis eight months ago. Two earlier, he developed pouchitis and received intensive treatment with infliximab (IFX). days after the IFX injection, a fever generalized rash appeared. Varicella zoster virus (VZV) antigen positivity blisters led to diagnosis of varicella. Based on history VZV vaccination, environmental conditions, antibody titers early stages disease, reactivation was suggested. The possibility...

Background: Gingival melanin pigmentation may cause esthetic concerns, even if no serious medical problem is present. As an inhibitor of formation, ascorbic acid often used to treat skin pigmentation. Thus, the present study investigated effects on gingival in vitro and vivo. Methods: The formation were evaluated B16 mouse melanoma cells three‐dimensional human models. In addition, a clinical trial was performed investigate inhibitory gel containing 2‐glucoside (AS‐G gel) This double‐masked,...

Background: Telomerase reverse transcriptase (TERT) promoter mutations have been found in a subset of papillary thyroid carcinomas (PTCs) and are associated with tumor aggressiveness worse prognosis. However, little is known about the status TERT mRNA expression its relationship between clinicopathological features. Methods: We analyzed 159 PTC samples for using direct DNA sequencing. was measured quantitative transcription polymerase chain reaction. To examine low allelic frequency high...

Primary cutaneous anaplastic large cell lymphoma (PC-ALCL) has a high relapse rate. However, it typically remains confined to the skin and favorable long-term prognosis. We describe case of PC-ALCL that experienced in central nervous system (CNS). The patient presented with somatosensory abnormalities extremities after local treatment lesions was diagnosed CNS PC-ALCL. Methotrexate, procarbazine, vincristine therapy, alternating brentuximab vedotin, followed by autologous hematopoietic stem...

E-cadherin has been studied extensively in other systems but little attention paid to its role wound healing. We investigated expression epithelial healing vivo by focusing on the migrating cells tongue and mitotic non-injured side apart from original edge.Round full-thickness excisional wounds (6 mm diameter) incisional were prepared dorsally mice. On various days after operation, was examined immunohistochemical staining using a monoclonal antibody specific for E-cadherin.In both models,...

We reported that soluble tumour necrosis factor receptor type 2 (sTNFR2)/type 1 (sTNFR1) ratios in gingival crevicular fluid (GCF) decreased as the severity of chronic periodontitis (CP) increased. This study investigated effects periodontal treatment on TNF-alpha, sTNFR1 and R2 GCF serum CP patients.Thirty-five 90 samples were obtained from 35 patients (23 non-smokers 12 smokers) at baseline after treatment. The levels quantified by enzyme-linked immunosorbant assay.No significant...

Abstract Background Sedentary behavior and decreased physical activity are associated with reduced kidney function, yet most evidence is based on self-reported activity. This study investigated the association between accelerometer-based level function in a general Japanese population. Methods A cross-sectional was conducted 440 community-dwelling participants, aged 35–79 years. Time (min/d) assessed for following types of activity: sedentary behavior, light (LPA), moderate-to-vigorous...

Herpes zoster infection occurs more frequently and severely in immunosuppressed populations. However, the condition sometimes presents with atypical clinical manifestations of skin, which makes it difficult to reach a correct diagnosis. We experienced case acral gangrene caused by varicella virus (VZV)-related vasculitis rheumatoid arthritis (RA) patient. Histologically, necrotic was observed; however, there were initially no findings epidermis suggestive viral infection. thought that skin...

The authors report a method of reconstruction full-thickness lower eyelid defect using blepharoplasty technique utilizing excess skin the with hard palate mucosal graft. In all patients mucosa took well, and good functional aesthetic results were obtained. most suitable indication this might be for occurring horizontally (for which direct closure is difficult to apply) located in lateral side (when large amount can utilized). conclude that although shape size applied restricted, useful...

The authors present their experience with 25 hard palate mucosa grafts used as lining material in the reconstruction of full-thickness alar defects. Good "take" was obtained 22 grafts; other three incurred necrosis overriding skin flaps and postoperative infection.
