Large population-based studies investigating the risks of overall and specific cancers among patients with hidradenitis suppurativa (HS) are limited.To assess cancer in HS compared without Republic Korea.A nationwide cohort study, using Korean Health Insurance Review Assessment Service database was conducted over a 2-year period from January 1, 2007, to December 31, 2008. Individuals control group who were never diagnosed or during washout randomly extracted matched by age, sex, index year,...
There is limited data on the risk of second primary malignancies (SPMs) in Asian melanoma survivors. This study aimed to identify SPMs Standardized incidence ratios (SIRs) were calculated for overall and specific SPMs. The factor SPM development was analyzed using a multivariable Cox regression model. A total 10,070 patients with included study. Melanoma survivors exhibited an increased (SIR, 1.51; 95% confidence interval [CI], 1.34–1.70). Additionally, more common among survivors, including...
Purpose This study aimed to investigate the effectiveness and safety of a new monopolar radiofrequency device equipped with 5 cm2 tip, against fine wrinkles around eyes cheeks.
Background: Filler injection has become an extremely popular method for facial skin rejuvenation, including the periorbital area. In recent years, new polynucleotide (PN)-containing filler products have been used esthetic purposes.Aim: We aimed to investigate efficacy and safety of PN in area.Patients/methods: A total 27 subjects were enrolled this randomized, pair-matched, active-controlled study. Each subject received injections thrice with two-week intervals, a on one side non-crosslinked...
Cold plasma can be beneficial for promoting skin wound healing and has a high potential of being effectively used in treating various wounds. Our aim was to verify the effect cold accelerating investigate its underlying mechanism vitro vivo. For vivo experiments, 2 full-thickness dermal wounds were created each mouse (n = 30). While one exposed daily treatments 3 min, other served as control. The evaluated by imaging histological analyses at 4, 7, 11 days post infliction process....
Abstract The morphology of facial scars shows a wide variation in terms texture and colour. To date, there are no reliable predictors aberrant scarring. We conducted retrospective analysis to identify factors associated with specific scar features types. Photographs medical records 428 patients were retrospectively reviewed. Patients keloids excluded. mean age the was 45.43 ± 23.13 years male‐to‐female ratio 1:1.36. Atrophic most common (42.8%), followed by flat (38.7%) hypertrophic (18.5%)....
The histopathological features of rosacea have not been described in detail.To evaluate the according to clinical characteristics such as subtype and severity.We retrospectively analyzed findings 226 patients with rosacea, which included 52 erythematotelangiectatic (ETR) 174 papulopustular (PPR) subtype. frequency each finding was compared between subtypes. Histopathological were also severity, through subgroup analysis within group.Perivascular perifollicular lymphohistiocytic infiltration...
Dear Editor: Adalimumab is a complete human monoclonal anti-tumor necrosis factor α (anti-TNFα) that generally well tolerated. With increasing use of adalimumab and other anti-TNFα therapies, several cutaneous adverse events have been reported during the therapy, including immune-mediated skin lesions1. A 39-year-old woman who had an 11-year history Crohn's disease was treated with (40 mg administered subcutaneously every week) presented at our clinic multiple achromic macules patches on...
Epidermal keratinocytes are considered as the most important neighboring cells that modify melanogenesis. Our previous study used microarray to show guanine deaminase (GDA) gene expression is highly increased in melasma lesions. Hence, we investigated role of GDA skin pigmentation. We examined post-inflammatory hyperpigmentation (PIH) lesions, diagnosed Riehl’s melanosis. further possible keratinocyte-derived melanogenesis by quantitative PCR, immunofluorescence staining, small interfering...
Ginsenosides of Panax ginseng are used to enhance skin health and beauty. The present study aimed investigate the potential use ginsenoside Rf (Rf) from as a new anti-pigmentation agent.The anti-melanogenic effects were explored. transcriptional activity cyclic adenosine monophosphate (cAMP) response element binding protein (CREB) expression levels tyrosinase, microphthalmia-associated transcription factor (MITF), tyrosinase-related proteins (Tyrps) evaluated in melanocytes UV-irradiated ex...
Dear Editor: The Harlequin syndrome, first described by Lance et al.1 in 1988, represents an uncommon disorder of the sympathetic nervous system. It is characterized unilateral diminished sweating and heat- or exercised-induced facial flushing. We present case one patient with this remarkable including a review literature. A 43-year-old woman presented to our clinic peculiar pattern She has been experiencing flushing on left side her face after physical exercise taking hot bath (Fig. 1)....
Dermatofibroma sometimes clinically presents as a nodular lesion without gross skin surface change. Clinicopathologic features of this variant dermatofibroma have not been evaluated.To assess clinicopathologic presenting subcutaneous nodule.This study reviewed the clinical and histological 42 cases dermatofibromas compared them with 95 conventional dermatofibroma.Dermatofibroma change was associated shorter pre-diagnosis duration than dermatofibroma. Increase in size during period...
Purpose Few studies have investigated the impact of biologics on risk major adverse cardiovascular events (MACEs) among Korean patients with psoriatic diseases. We compared MACEs and all-cause mortality disease treated tumor necrosis factor (TNF)-α interleukin (IL)-12/23 inhibitors in Korea.
