Behçet's disease is a chronic relapsing multisystemic inflammatory disorder characterized by four major symptoms (oral aphthous ulcers, genital ulcers, skin lesions, and ocular lesions) and occasionally by five minor symptoms (arthritis, gastrointestinal ulcers, epididymitis, vascular lesions, and central nervous system symptoms). Although the etiology of Behçet's disease is still unknown, there have been recent advances in immunopathogenic studies, genome-wide association studies, animal models, diagnostic markers, and new biological agents. These advances have improved the clinical understanding of Behçet's disease and have enabled us to develop new treatment strategies for this intractable disease, which remains one of the leading causes of blindness.
The results of this study shows that the 308-nm excimer laser can be an effective and promising device for the treatment of various vitiligo types, other than generalized, in childhood.
Our findings demonstrate that the use of non-ablative and/or ablative fractional lasers promoted hair growth in certain cases of uncommon hair disorders without any remarkable side effects.
Background: Female patients with atopic dermatitis (AD) often experience cutaneous deterioration associated with their pregnancy or menstrual cycle. Objective: We wanted to determine the prevalence of symptom aggravation as related to pregnancy and the menstrual cycle in female patients with AD. Methods: One hundred female patients with AD were included in the study and interviews were performed. The total IgE level and the Eczema Area and Severity Index score of the patients were retrospectively reviewed. Results: Ninety seven patients replied the questionnaire, and among them, 23 patients had completed at least 1 pregnancy. Among the 23 women who experienced pregnancy, 14 (61%) had noticed deterioration of their clinical symptoms during pregnancy. Of the 97 females, 31 (32%) patients had noticed deterioration of their AD as related to their menstrual cycle. For the patients who were sub-grouped as the intrinsic type of AD, the prevalence of symptom aggravation as related to pregnancy was significantly higher as compared to that of the extrinsic type of AD patients (p=0.048). Conclusion: Of the 97 patients, 45 (46%) females answered that they have experienced deterioration of AD during pregnancy or in relation to their menstrual cycle, and this suggests the relation of a hormonal influence on the clinical manifestations of AD.

There have been much interest and many efforts to control global warming and reduce greenhouse gas (GHG) emissions throughout the world. Recently, the Republic of Korea has also increased its GHG reduction goal and searched for an implementation plan. In buildings, for example, there have been technology developments and deployment policies to reduce GHG emissions from a life cycle perspective, covering construction materials, building construction, use of buildings and waste disposal. In particular, Korea's Green Standard for Energy and Environmental Design is a certification of environmentally-friendly buildings for their energy saving and reduction of environmental pollution throughout their lives. In fact, the demand and adoption of the certification are rising every year. In construction materials and buildings, as a result, an environmentally-friendly aspect has become crucial. The importance of construction material and building development technologies that can reduce environmental load by diminishing GHG emissions in buildings has emerged. Moreover, there has been a rising necessity to verify the GHG reduction effects of buildings. To assess the reduction of carbon emissions in the buildings built with low-carbon construction technologies and materials, therefore, this study estimated life cycle carbon emissions in reference buildings in which general construction materials are used and in low-carbon buildings. For this, the carbon emissions and their reduction from construction materials (especially concrete) between conventional products and low-carbon materials were estimated, using Life Cycle Assessment (LCA). After estimating carbon emissions from a building life cycle perspective, their reduction in low-carbon buildings compared to the reference buildings was reviewed. The results found that compared to conventional buildings, low-carbon buildings revealed a 25% decrease in carbon emissions in terms of the reduction of Life Cycle CO 2 (LCCO 2 ) per unit area. If diverse production technologies and sales routes are further developed for low-carbon construction materials, carbon emission reduction effects would considerably increase.
Background: Cases of non-scarring alopecia after endovascular brain surgery have been reported, but dermoscopic findings of these lesions have rarely been published. Objective: To report the dermoscopic findings for alopecic skin lesions that developed after radiation exposure during angioembolization. Methods: Dermoscopic examination was used to evaluate alopecic skin lesions in 10 patients who presented with post-angioembolization alopecia. Results: The male to female ratio was 1:4, mean age 55.0 ± 12.3 years and mean duration to lesion development 3.4 ± 2.5 weeks. The rectangular-shaped lesions mostly occurred at the occiput and temple areas. Both yellow and black dots were the predominant dermoscopic findings in 60% (6/10) of patients, followed by short vellus hair (50%), peripilar sign (20%), broken hair (10%), coiled hair (10%) and white dots (10%). Conclusions: Alopecic skin lesions induced by radiation exposure during angioembolization share characteristic dermoscopy findings with alopecia areata. They may be misdiagnosed if a precise history is not obtained.
Behçet's disease (BD) is a chronic, multisystemic vasculitis that theoretically affects all sizes and types of blood vessels. Although pathogenesis remains enigmatic, endothelial cells are believed to be the primary target in this disease. We detected the target protein using western blotting and immunoprecipitation and determined the amino-acid sequence of the peptide by liquid chromatography-matrix assisted laser desorption/ionization-tandem time-of-flight analysis (LC-MALDI-TOF/TOF). Serum reactivity against the recombinant target protein was analyzed by immunoblotting. Serum reactivity against streptococcal 65-kD heat shock protein (hsp-65) and the recombinant target protein was investigated by ELISA. The 36-40-kD protein band that was obtained from immunoprecipitation, which was analyzed by LC-MALDI-TOF/TOF, exhibited the amino-acid sequences of heterogeneous nuclear ribonucleoproteins A2/B1 (hnRNP-A2/B1). Reactivity of serum IgA against human recombinant hnRNP-A2/B1 was detected in 25 of 30 BD patients (83.3%), 4 of 30 systemic lupus erythematosus patients (13.3%), 8 of 30 rheumatoid arthritis patients (26.7%), 9 of 30 Takayasu's arteritis patients (30%), 6 of 30 healthy controls (20%), and none of 30 IgA nephropathy patients. Optical densities obtained from ELISAs against the recombinant human hnRNP-A2/B1 were correlated with those against the recombinant streptococcal hsp-65.JID JOURNAL CLUB ARTICLE: For questions, answers, and open discussion about this article, please go to http://www.nature.com/jid/journalclub.
FPS and CO2 FS were both effective and safe for the treatment of scars, and can also be used together safely as a combination treatment. The proper laser device and proper treatment time should be decided considering various factors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
