RESUMO
Background@#Currently, there is no consensus on the treatment of psoriasis in Korean patients. @*Objective@#This study aimed to establish a consensus on the basic therapeutic principles for Korean patients with plaque psoriasis. @*Methods@#Using the modified Delphi method, a steering committee proposed 53 statements for the first Delphi round, which covered five subjects: (1) the goal of treatment and evaluation of disease severity, (2) topical therapy, (3) phototherapy, (4) conventional systemic therapy, and (5) biologic therapy. The panel of dermatologists scored the level of agreement for each statement on a ten-point scale with scores ranging from 1 (strongly disagree) to 10 (strongly agree). After discussing the results of the first round, the committee reformulated 41 statements. Finally, consensus was defined as more than 70% of the second round scores being ≥7. @*Results@#The panel participants strongly agreed that the ideal treatment goals for Korean patients with plaque psoriasis should include complete skin clearance and high dermatological quality of life. A strong consensus was also reached on the use of topical agents for psoriasis of any severity, the consideration of phototherapy before biologics therapy, the conventional systemic agents for moderate-to-severe psoriasis, and the recommendation of biologic for retractable psoriasis to conventional systemic therapy and phototherapy. @*Conclusion@#This modified Delphi panel established an expert consensus on the therapeutic approach for Korean patients with plaque psoriasis. This consensus may improve the treatment outcomes for psoriasis in Korea.
RESUMO
Background@#Psoriasis is a chronic disease that can have accompanying comorbidities including arthritis, metabolic syndrome, and cardiovascular diseases. Patients with psoriasis tend to frequently visit medical institutions, and their economic burden for medical services is high. @*Objective@#To investigate the economic burden of psoriasis in Korea. @*Methods@#The Korean Society for Psoriasis conducted a multi-center field survey of the patients and analyzed the national insurance claim data. Also, we discussed the medical environment of psoriasis in Korea based on the results. @*Results@#The economic burden of psoriasis patients is substantial and varied by the type of medical institute. Patients also paid the indirect and intangible medical costs. Biological agents, which is used in patients with severe psoriasis, led to an increase in the cost. @*Conclusion@#This is the first study to estimate the economic burden of psoriasis in Korea comprehensively. To improve the medical environment of psoriasis and alleviate the burden of patients, discussion on the more efficient health policy and medical insurance criteria for psoriasis would be needed.
RESUMO
Background@#An evident relationship has been shown between psoriasis and metabolic comorbidities. However, the results in pediatric psoriasis vary from study to study, and no meta-analysis exists on the association of metabolic comorbidities with pediatric psoriasis. Objective: To evaluate the association between psoriasis and metabolic comorbidities in pediatric patients. @*Methods@#We searched articles published in PubMed, EMBASE, and Cochrane Library databases from inception to April 30, 2019. All observational studies reporting the prevalence of obesity or metabolic comorbidities in pediatric patients with psoriasis were included. @*Results@#The meta-analysis included 16 unique studies meeting the inclusion criteria. The pooled odds ratios in pediatric patients with psoriasis was 2.40 (95% confidence interval [CI], 1.60∼3.59) for obesity (13 studies), 2.73 (95% CI, 1.79∼ 4.17) for hypertension (8 studies), 2.01 (95% CI, 1.09∼3.73) for diabetes mellitus (8 studies), 1.67 (95% CI, 1.42∼1.97) for dyslipidemia (7 studies), and 7.49 (95% CI, 1.86∼30.07) for metabolic syndrome (4 studies). @*Conclusion@#Pediatric patients with psoriasis showed a significantly higher prevalence of obesity, hypertension, diabetes, dyslipidemia, and metabolic syndrome. Adequate monitoring and timely management of metabolic comorbidities should be considered in these patients.

RESUMO
Background/Aims@#There are concerns that the use of renin-angiotensin system (RAS) blockers may increase the risk of being infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or progressing to a severe clinical course after infection. This this study aimed to investigate the influence of RAS blockers on the risk and severity of SARS-CoV-2 infection. @*Methods@#We conducted a retrospective cohort study analyzing nationwide claims data of 215,184 adults who underwent SARS-CoV-2 tests in South Korea. The SARS-CoV-2 positive rates and clinical outcomes were evaluated according to the use of RAS blockers in patients with hypertension (n = 64,243). @*Results@#In total, 38,919 patients with hypertension were on RAS blockers. The SARS-CoV-2 positive rates were significantly higher in the RAS blocker group than in the control group after adjustments (adjusted odds ratio [OR], 1.22; 95% confidence interval [CI], 1.10 to 1.36; p < 0.001), and matching by propensity score (adjusted OR, 1.16; 95% CI, 1.03 to 1.32; p = 0.017). Among the 1,609 SARS-CoV-2-positive patients with hypertension, the use of RAS blockers was not associated with poor outcomes, such as mortality (adjusted OR, 0.81; 95% CI, 0.56 to 1.17; p = 0.265), and a composite of admission to the intensive care unit and mortality (adjusted OR, 0.95; 95% CI, 0.73 to 1.22; p = 0.669). Analysis in the propensity scorematched population showed consistent results. @*Conclusions@#In this Korean nationwide claims dataset, the use of RAS blockers was associated with a higher risk to SARS-CoV-2 infection but not with higher mortality or other severe clinical courses.
RESUMO
PURPOSE: Despite the successful use of tyrosine kinase inhibitors (TKIs) in cancer patients, their effect on herpes zoster development has not been studied. The aim of this study was to evaluate and compare the effects of epidermal growth factor receptor (EGFR) TKI and cytotoxic chemotherapy on the risk of herpes zoster development in non-small cell lung cancer (NSCLC) patients. MATERIALS AND METHODS: We conducted a medical review of all eligible NSCLC patients in Seoul National University hospital between 2002 and 2015. We classified patients based on whether they previously underwent EGFR TKI therapy into either the TKI group or the cytotoxic group. We compared the incidence rates of herpes zoster during TKI therapy and cytotoxic chemotherapy. Additionally, the longitudinal risk of herpes zoster from TKIs was analyzed using the incidence rate ratio (IRR) of the TKI group to the cytotoxic group and the log-rank test of the Kaplan-Meier method. RESULTS: Of the 2,981 NSCLC patients, 54 patients (1.54%) developed herpes zoster. In the TKI group (2,002 patients), the IRR of herpes zoster during TKI therapy compared to that during cytotoxic chemotherapy was 1.05 (95% confidence interval [CI], 0.53 to 2.09). The IRR of the TKI group compared to the cytotoxic group was 1.33 (95% CI, 0.64 to 2.76). The Kaplan-Meier cumulative risk of both groups was not significantly different. CONCLUSION: Our results show that the incidence rate of herpes zoster in the TKI group was not statistically different from the incidence in the cytotoxic group during and after chemotherapy in NSCLC patients.

PURPOSE: Patients treated with anticancer agents often experience a variety of treatment-related skin problems, which can impair their quality of life. MATERIALS AND METHODS: In this cross-sectional study, Dermatology Life Quality Index (DLQI) and clinical information were evaluated in patients under active anticancer treatment using a questionnaire survey and their medical records review. RESULTS: Of 375 evaluated subjects with anticancer therapy, 136 (36.27%) and 114 (30.40%) were treated for breast cancer and colorectal cancer, respectively. We found that women, breast cancer, targeted agent use, and longer duration of anticancer therapy were associated with higher dermatology-specific quality of life distraction. In addition, itching, dry skin, easy bruising, pigmentation, papulopustules on face, periungual inflammation, nail changes, and palmoplantar lesions were associated with significantly higher DLQI scores. Periungual inflammation and palmoplantar lesions scored the highest DLQI. CONCLUSION: We believe our findings can be helpful to clinicians in counseling and managing the patients undergoing anticancer therapy.

BACKGROUND: Although psoriasis is universal in its occurrence worldwide, its prevalence varies by geographic location and race. A few hospital-based surveys have reported on the demographic characteristics in Korean patients with psoriasis. However, a nation-wide study on the prevalence of psoriasis in Korea remains uncompleted. OBJECTIVE: The purpose of this study was to determine the prevalence of psoriasis in Korea and to describe the demographic and social characteristics of afflicted individuals. METHODS: We identified patients with psoriasis using a relevant diagnostic code from the sixth revision of the Korean Standard Classification of Disease in the 2011~2015 claims database of the Health Insurance Review and Assessment Service of Korea. We estimated the annual prevalence of psoriasis and described the age and sex distribution of the patients, type and severity of psoriasis, comorbidities, type of health insurance, type of health-care institution and residence area. Patients with moderate-to-severe psoriasis were defined as those who had been treated with phototherapy, classical systemic agents, and/or biologic agents. RESULTS: The standardized prevalence of psoriasis was 453 per 100,000 individuals of the database population in 2015. We found male preponderance with a 1.3:1 male-to-female ratio, and that the largest number of patients belonged to the age group of 50s. Of the patients diagnosed with psoriasis in 2015, 83.8% had plaque psoriasis and 22.6% had moderate-to-severe psoriasis. CONCLUSION: The annual standardized prevalence of psoriasis in Korea was 453 per 100,000 of the population in 2015.

BACKGROUND AND OBJECTIVES: Radiofrequency catheter ablation (RFCA) exposes patients to fixed angle radiation for extended periods of time. We investigated the incidence and characteristics of radiation-induced dermatitis (RID) associated with RFCA. SUBJECTS AND METHODS: We screened 1347 consecutive patients from 2000 to 2011 who underwent RFCA for any indication and reviewed patients with dermatologic issues at the 1-month follow-up. Skin lesions were classified into three groups: most likely RID, probable RID, and possible RID. RESULTS: Of the 1347 enrolled patients, 12 (0.89%) experienced dermatologic issues within 1 month after RFCA, including six patients (0.45%) clinically classified as 'most likely RID' and four patients (0.30%) with 'probable RID'. Ten patients, including most likely RID or probable RID patients, developed skin lesions on the right back and upper arm. Skin lesions did not improve without meticulous treatment, and three cases required surgical intervention. We compared the RID group to the remaining 1335 patients (normal group). The mean body mass indices (BMIs) of the RID and normal groups were 29.3 and 23.9 kg/m², respectively (p26 kg/m2 and exposure times >115 minutes based on receiver operator characteristic curve analyses. Among the 35 patients without RID, 29 patients (82.9%) did not use biplane fluoroscopy. CONCLUSIONS: Patients with high BMIs have a higher risk of developing severe RID with increasing fluoroscopy times using biplane fluoroscopy.

Sebaceoma, also known as sebaceous epithelioma, is a rare, benign, adnexal tumor with sebaceous differentiation. It usually appears as a yellowish papule, nodule, or plaque on the scalp and face, on which there are abundant sebaceous glands. Histologically, it is a well-circumscribed lesion composed of undifferentiated basaloid cells and mature sebaceous cells in relatively preserved lobulated architectures. A 31-year-old woman presented with a 1.3-cm ×1.1-cm nodule on the right earlobe. Mohs micrographic surgery was performed to completely remove it. Histopathological examination revealed that mature sebaceous cells with scalloped nuclei and focal cystic change were present in the lobule.

RESUMO
Various treatment modalities are available for mycosis fungoides including topical steroids, topical chemotherapy, phototherapy, and spot radiation therapy. However, these modalities do not always result in optimal effects, with efficacy depending on lesion size, number, and location. Photodynamic therapy (PDT) is a recently introduced therapeutic modality that proved effective in patients with unilesional mycosis fungoides. A 58-year-old woman presented with a seven-year history of a pruritic erythematous scaly patch on her right thigh. Through skin biopsy, we verified the lesion as mycosis fungoides. The lesion did not respond well to a topical steroid. We opted for topical PDT with methyl-aminolevulinate (MAL). MAL cream was applied for 4 hours following irradiation with a red light. Four sessions were administered, separated by five weeks. The lesion clinically improved after treatment without severe side effects. PDT using MAL could be considered an effective and tolerable treatment for mycosis fungoides.

In full-thickness defects of the nasal alar rim, to achieve projection and maintain airway patency, cartilage graft is frequently needed. However, cartilage graft presents a challenge in considerations such as appropriate donor site, skeletal shape and size, and healing of the donor area. To avoid these demerits, we tried primary closure of alar rim defects by also making the contralateral normal ala smaller. We treated two patients who had a full-thickness nasal alar defect after tumor excision. Cartilage graft was considered for the reconstruction. However, their alar rims were overly curved and their nostril openings were large. To utilize their nasal shape, we did primary closure of the defect rather than cartilage graft, and then downsized the contralateral nasal ala by means of wedge resection to make the alae symmetric. Both patients were satisfied with their aesthetic results, which showed a smaller nostril and nearly straight alar rims. Moreover, functionally, there was no discomfort during breathing in both patients. We propose our idea as one of the reconstruction options for nasal alar defects. It is a simple and easy-to-perform procedure, in addition to enhancing the nasal contour. This method would be useful for patients with a large nostril and an overly curved alar rim.

BACKGROUND: The efficacy of the long-pulsed diode laser (LPDL) in hair removal is determined with various physical parameters. Recently, LPDLs with a larger spot size are commercially available; however, the independent effect of spot size on hair removal has not been studied. OBJECTIVE: This study aimed to compare the efficacy of the LPDL in hair removal depending on the spot size. METHODS: A randomized, evaluators-blind, intrapatient comparison (left vs. right) trial was designed. Ten healthy Korean women received three hair removal treatment sessions on both armpits with the 805-nm LPDL and followed for 3 months. A 10x10 mm handpiece (D1) or a 10x30 mm handpiece (D3) was randomly assigned to the right or left axilla. The fluence, pulse duration, and epidermal cooling temperature were identical for both armpits. Hair clearance was quantified with high-resolution photos taken at each visit. Postprocedural pain was quantified on a visual analogue scale. Adverse events were evaluated by physical examination and the patients' self-report. RESULTS: The mean hair clearance at 3 months after three treatment sessions was 38.7% and 50.1% on the armpits treated with D1 and D3, respectively (p=0.028). Procedural pain was significantly greater in the side treated with D3 (p=0.009). Serious adverse events were not observed. CONCLUSION: Given that the pulse duration, fluence, and epidermal cooling were identical, the 805-nm LPDL at the three times larger spot size showed an efficacy improvement of 29.5% in axillary hair removal without serious adverse events.

BACKGROUND: Human epidermal gammadelta T cells are known to play crucial roles in the defense and homeostasis of the skin. However, their precise mechanism of action in skin inflammation remains less clear. OBJECTIVE: In this study, we analyzed the cytokine expression profile of human epidermal gammadelta T cells and compared it to that of peripheral blood gammadelta T cells to investigate the specific activity of epidermal gammadelta T cells in modulating skin inflammation. METHODS: We isolated gammadelta T cells from epidermal tissue or peripheral blood obtained from healthy volunteers. Isolated gammadelta T cells were stimulated using immobilized anti-CD3 antibody and interleukin-2 plus phytohaemagglutinin, and were then analyzed using a cytokine array kit. RESULTS: Both epidermal and peripheral blood gammadelta T cells produced comparable levels of granulocyte-macrophage colony-stimulating factor, I-309, interferon-gamma, macrophage migration inhibitory factor, macrophage inflammatory protein-1alpha, and chemokine (C-C) ligand 5. The epidermal gammadelta T cells produced significantly higher levels of interleukin-4, -8, -13, and macrophage inflammatory protein-1beta than the peripheral blood gammadelta T cells did. Notably, the epidermal gammadelta T cells produced several hundred-fold higher levels of interleukin-13 than interleukin-4. CONCLUSION: These results suggest that the epidermal gammadelta T cells have a stronger potential to participate in the Th2-type response than the peripheral blood gammadelta T cells do. Furthermore, epidermal gammadelta T cells might play an important role in the pathogenesis of Th2-dominant skin diseases because of their active production of interleukin-13.

Lentigo maligna is a variant of melanoma in situ that appears on sun-exposed areas as a macule with variegated pigmentation and irregular borders. If untreated, it has a risk of progressing to lentigo maligna melanoma. Two patients presented with hyperpigmented macules or patches on atypical facial areas. The histological findings were consistent with lentigo maligna. An 80-year-old Korean woman presented with clustered hyperpigmented macules on the lower lip and oral mucosa, and a 45-year-old Caucasian presented with a lesion located on the external auditory meatus, with intermittent sun exposure. Herein, we report two interesting cases of lentigo maligna with atypical clinical presentations.
