Abstract
BACKGROUND Despite its rarity, porphyria cutanea tarda (PCT) is globally recognized as the most common form of cutaneous porphyria. This study aims to review the underlying associations and treatment of PCT in Scotland. METHODS We retrospectively reviewed data on 27 patients diagnosed with PCT between 1987 and 2022 at the Scottish Cutaneous Porphyria Service. RESULTS Males slightly predominated (66.7%). The mean ± standard deviation (SD) age at diagnosis was 55.6 ± 12.5 years. Common associated factors were heavy alcohol intake (88.5%), genetic hemochromatosis (72%), smoking (45.5%), and hepatitis C virus infection (16%). Most had multiple associated factors (70.4%). Patients with genetic hemochromatosis with the C282Y genotype exhibited higher median transferrin saturation (69.5 vs. 35, P = 0.004) and ferritin levels (observed in males only) (1175 vs. 339; P = 0.014) than those with the H636D genotype. Most (52%) received combination therapy of venesection and antimalarials, followed by venesection monotherapy (32%) and antimalarial monotherapy (16%). Overall, 95.2% achieved biochemical improvement. Median time to improvement was 7, 5, and 9 months with venesection, antimalarial, and combined treatments, respectively (P = 0.173). Biochemical remission was achieved in 50% of patients. Remission occurred in 2/4 of patients with antimalarial monotherapy (median time 19 months) and 9/13 patients with combined treatment (median time 26 months). Biochemical relapse was found in three patients, all of whom received combination therapy. CONCLUSION Excess alcohol intake and genetic hemochromatosis were the most common underlying associations with PCT in our Scottish cohort. Treatment for PCT should be individualized, and long-term follow-up is needed to monitor for disease relapse.

Abstract
Our study highlights the high prevalence of early-onset chronic actinic dermatitis (CAD; age < 40 years at diagnosis), particularly in patients with atopic diseases and those with darker skin phototypes. Disease characteristics, photodiagnostic investigations and outcomes did not significantly differ between those with early-onset vs. late-onset disease, although younger patients more frequently required systemic therapy. We also show that marked UVA sensitivity and positive baseline series patch testing are negative prognostic factors for outcomes in CAD.

Abstract
BACKGROUND There is an urgent need for noninvasive tests to identify patients with psoriasis at risk of significant liver fibrosis. OBJECTIVES To externally validate the ability of the Steatosis-Associated Fibrosis Estimator (SAFE) score to detect significant liver fibrosis in patients with psoriasis using transient elastography (TE) as a reference. METHODS We analysed data from 75 patients with psoriasis, including TE, SAFE score, Fibrosis-4 Index (FIB-4) and Nonalcoholic Fatty Liver Disease Fibrosis Score (NFS). Significant liver fibrosis was defined as TE values ≥ 7.1 kPa. Diagnostic accuracy was assessed using the area under the receiver operating characteristic curve (AUROC). RESULTS Fifteen patients (20%) exhibited significant liver fibrosis. The AUROCs for the SAFE and FIB-4 scores were 0.82 [95% confidence interval (CI) 0.67-0.97] and 0.62 (95% CI 0.45-0.79), respectively. The SAFE score outperformed the FIB-4 Index (P = 0.01) but was comparable with the NFS (P = 0.05) in predicting significant fibrosis. Using thresholds of < 0, 0 to < 100 and ≥ 100, the SAFE score categorized 36, 24 and 15 patients into low, intermediate and high-risk groups for significant fibrosis, respectively. The negative predictive value for excluding significant fibrosis with a SAFE score of < 0 was 94.4%, and the positive predictive value for diagnosing significant fibrosis with a SAFE score of > 100 was 53.3%. The duration of psoriasis, joint involvement and methotrexate treatment did not affect the diagnostic ability of the SAFE score whereas age of the patient did. CONCLUSIONS The SAFE score demonstrated good accuracy in assessing clinically significant fibrosis among patients with psoriasis. This score should prove valuable for risk stratification and patient management in dermatology practice.

Abstract
BACKGROUND Footwear contact allergy is caused by exposure to allergens in shoes. The prevalence and common allergens vary by region and time due to differences in customs and lifestyle. OBJECTIVES To determine the clinical characteristics and common allergens of patients with footwear-related allergic contact dermatitis (ACD) who attended Siriraj Hospital in Bangkok, Thailand, between 2001 and 2020. METHODS The medical records of 247 patients with clinically suspected footwear dermatitis who underwent patch testing were reviewed. RESULTS The prevalence of ACD to footwear was 1.8%. Females were predominant (71.6%). The three most common allergens were carba mix (7.7%), mercapto mix (6.9%) and potassium dichromate (6.9%). According to the allergens found, rubber (14.2%), adhesives (7.7%) and leathers (6.9%) were the three most common groups. Dorsal-limited skin lesions were significantly associated with footwear ACD. CONCLUSION Rubber and leather allergens were still the most common culprit allergens. Dermatologists should keep up-to-date on common allergens in footwear and emerging allergens to include in patch test series.

Abstract
Background The COVID-19 pandemic may alter individuals' perspectives and behaviors regarding sun exposure and photoprotection. Presently, there is a paucity of information about how the pandemic influences photoprotection in photodermatoses and melasma. Objective To compare the photoprotection attitudes and behaviors of individuals with photodermatoses and melasma with those of a control group (other dermatologic patients) before and during the COVID-19 pandemic. Methods A questionnaire-based, cross-sectional study was conducted among Thai patients with photodermatoses, melasma, and other dermatological conditions between August 2021 and November 2022. Each of the three groups consisted of 35 patients. Results Among the 105 patients, 81.9% were female, and the mean age was 45.83 years. Over 80% of individuals who used surgical masks daily for 4 to 8 hours believed that these masks provided skin protection from the sun. The duration of sun exposure and the frequency of photoprotection practices decreased significantly in all groups during the COVID-19 pandemic compared to the pre-pandemic period. Sunscreen was the most prevalent form of photoprotection, but its usage declined considerably during the pandemic. Upon physical examination, the photodermatoses and control groups exhibited unchanged skin conditions, while the patients with melasma demonstrated improved skin conditions during the pandemic. Conclusion Owing to increased indoor activities and the perception that face masks could block sunlight, the COVID-19 pandemic led to notable reductions in sun exposure and photoprotective practices. Despite the absence of photodermatoses exacerbation and the observed improvements in patients with melasma, consistent and effective photoprotection must continue to be promoted.

Abstract
Despite the significant prevalence of pruritus in psoriasis, its pathogenesis remains unknown, and research on pruritus in Thai psoriasis patients is limited. Objectives The objective was to investigate the prevalence and clinical characteristics of pruritus, and the factors significantly associated with high pruritic intensity in Thai psoriasis patients. Material and methods In a cross-sectional study design, pruritus data were collected from the medical records of patients who attended an outpatient psoriasis clinic in Thailand between 2020 and 2021. Results The overall prevalence of pruritus was 81.2% among 314 psoriasis patients. Psoriasis patients with pruritus had higher Psoriasis Area Severity Index and Dermatology Life Quality Index scores than those without pruritus. The legs, back, arms, and scalp were the most common areas for pruritus. Pruritus was relieved with topical emollients, topical corticosteroids, and oral antihistamines in 66.3, 63.1, and 52.9% of patients, respectively. Female sex, psoriasis body surface area greater than or equal to 10%, and genital psoriasis were factors that independently predicted high pruritus intensity. Conclusion Psoriasis patients should be screened and treated for pruritus to improve both psoriasis treatment outcomes and patient quality of life. Further studies are needed to clarify the most effective medications for pruritus in patients with severe psoriasis.

Abstract
Bimatoprost ophthalmic solution 0.03% (PGF2α analogues) combined with narrowband ultraviolet B (NB-UVB) was reported to be an effective treatment for vitiligo. To investigate the efficacy and safety of treatment for non-segmental/segmental vitiligo compared among bimatoprost ophthalmic solution 0.01% combined with NB-UVB phototherapy, bimatoprost monotherapy, and placebo. This single-blind randomized controlled study enrolled stable Thai vitiligo patients with at least three similarly sized lesions in the same anatomical area. The treatment duration was 6 months with 1- and 2-month post-treatment follow-ups. The 3 selected lesions on each patient were randomized to receive combination therapy, monotherapy, or placebo. The Vitiligo Area Scoring Index (VASI) was used to evaluate lesion response. Of the 25 initially enrolled subjects, 19 patients were analyzed. There were 13 and 6 non-segmental and segmental vitiligo cases, respectively. Eight and 11 cases had face/neck and non-face/neck lesions, respectively. Non-segmental vitiligo and non-face/neck vitiligo patients in the combination group had significant improvement in VASI score at 3 months, 6 months, and at the 2-month follow-up. No side effects were observed/reported. Bimatoprost combination therapy was shown to be safe and effective for treating Thai patients with non-segmental vitiligo in non-face/neck areas of the body.

Abstract
This study evaluated the impacts on psoriasis flares of 3 vaccine platforms: inactivated, viral vector and mRNA. Respectively, 198 and 96 psoriasis patients with and without COVID-19 vaccination during the study period. Group comparison revealed no increased risk of psoriasis flaring after COVID-19 vaccination. The vaccinated group received 425 doses of vaccine (140 inactivated, 230 viral vector and 55 mRNA). Patients' self-reported symptoms included all three platforms causing psoriasis flare, but the highest was among patients administered with mRNA vaccines. Most flares were mild to moderate, and most patients (89.8%) managed their flare-up lesions without rescue therapy. In conclusion, our study showed that the rate of psoriasis flare was not significantly different between vaccinated and unvaccinated groups. Factors that might explain psoriasis flare include vaccine-related psychological stress and side effects from vaccination. Different platforms of corona vaccines seemed to have different impact of psoriasis flares. Based on our results and the recommendations of several consensus guidelines, the benefits of COVID vaccinations outweigh the risks to patients with psoriasis. Patients with psoriasis should receive a COVID vaccine as soon as one is available.

Abstract
Objective: Photodermatoses are a group of cutaneous disorders with abnormal reactions triggered by exposure to sunlight. Previous studies reported varying photodermatoses prevalence in Caucasians and African-Americans; however, it was seldom reported in the Asian population. The aim of our study was to determine the prevalence, clinical characteristics and trend of photodermatoses in Thailand.
Materials & Methods: A retrospective chart review was performed at the Faculty of Medicine Siriraj Hospital, Mahidol University using diagnoses from the International Classification of Disease (ICD), Tenth Revisions codes, between January 2005 and September 2021.
Results: A total of 561 patients with definite diagnosis of photodermatoses were identified. The prevalence of photodermatoses in the outpatient dermatology clinic was 3 cases per 1,000. The most common photodermatoses was chemical and drug-induced photosensitivity (39.4%), followed by immunologically-mediated photodermatoses (30.1%), photo-aggravated dermatoses (29.4%) and genophotodermatoses (1.1%). Overall phototesting was performed in 276 cases (49.2%). In our study, some photodermatoses had unique clinical characteristics including pinpoint popular variant of polymorphous like eruption and adult-onset actinic prurigo. Over 16 years, the trend of patients being diagnosed with photodermatoses has continued to rise gradually with an increment of 1.67 times.
Conclusion: Photodermatoses are uncommon in Thailand. Some photodermatoses have distinctive clinical features in Asian populations. The trend of photodermatoses in Thailand is continually rising, reflecting an increase in physicians’ awareness and knowledge of these cutaneous conditions.

Abstract
Objective: To identify trends of contact allergy and patch testing amendments at the Contact Dermatitis Clinic, Department of Dermatology, Siriraj Hospital.
Materials and Methods: Medical records of 6,862 patients referred to our clinic between January 1992 and December 2021for patch testing were reviewed.
Results: The number of patients patch tested increased and reached a peak of 600 patients/year in 2019 before the COVID-19 pandemic. The most frequently used series was baseline, while the most used specific series was cosmetics. The overall positivity rate was 69%. The highest positivity rate was in the cosmetics series (70.2%). Nickel sulfate was the most common contact allergen found (24.2%).
Conclusion: Our patch test service has been growing in the last 30 years. The series of allergens used for patch testing has been amended every few years to be up-to-date with current global trends of contact allergies. Continual surveillance of contact prevalence and periodic updating of those series are necessary to enhance our ability to detect culprit contact allergens, which could help us improve care of our patients.

Abstract
BACKGROUND A wide range of sunscreen products are available globally. Designed to meet various customer needs, they differ in formulations type, textures, ingredients, ultraviolet (UV) protection capabilities, and other properties. Knowing the factors influencing the purchase of sunscreens and the UV filters commonly used in each global region would be beneficial for dermatologists, consumers, and regulators. METHODS Data on 50 best-selling sunscreens from each of 20 countries on 5 continents (1000 products in all) were retrieved from Amazon Marketplace during the period from January to July 2021. RESULTS Among the 5 continents, Asia had the highest proportion of consumers (71.1%) choosing high sun protection factor (SPF) sunscreens (SPF ≥50). In contrast, Europe had the highest percentage (11.8%) purchasing <30 SPF sunscreens. The lack of standard UVA protection labeling was significantly highest in South America. The use of inorganic-based sunscreen was highest in North America, and across all continents, those products were significantly more expensive than organic-based sunscreens. Globally, lotions were the most favored formulation type. "Nongreasy/dry touch" (45.1%) and "lightweight texture" (40.4%) were the most common promotional terms used. The most common UV filters differed among regions. Iron oxide, which can function as a visible light filter, was most frequently found in sunscreens in South America (20%) and North America (19.3%). CONCLUSIONS The regional factors influencing the purchase of sunscreen products differed. A considerable number of sunscreens may not provide adequate sun protection for consumers. Dermatologists should recommend sunscreens with sufficient UV protection that suit the skin of individual consumers.

Abstract
Objective: To determine the proportion of patients with psoriasis prepared to pay for TD. Attitudes and factors influencing their willingness to pay (WTP) were evaluated.Materials and Methods: This cross-sectional study was conducted from July 2020 to October 2021. Adult patients with psoriasis completed a 2-page self-administered questionnaire.Results: Of 200 patients, 133 (66.5%) were unfamiliar with TD. However, 144 (72%) were prepared to pay for TD if it were introduced. The majority of patients answered that 300 Bath was the maximum price that they were willing to pay for TD service. Compared with traditional in-person visits, the significant positive influencing factors on WTP were TD’s quicker delivery of treatment, lower costs, and non-inferiority to usual care. Multivariate analysis showed that the independent factors for WTP were higher educational levels, elimination of out-of-pocket, in-hospital visit expenses, owning a business, TD options suited to psoriasis, and no adverse effects on the patient-doctor relationship.Conclusion: Knowing patients’ attitudes toward TD and the factors influencing their WTP is essential for developing efficient services. Data from this study can be used to develop successful TD services for patients with psoriasis.

Abstract
Methotrexate (MTX) has long been considered the first-line oral systemic pharmacotherapy for psoriasis. The drug has several well-known systemic side effects, such as bone marrow suppression and hepatotoxicity. To avoid them, the use of topical or intralesional administrations of MTX has become an interesting option. With the advent of novel drug delivery systems, especially nanocarriers, the usage of a high-efficacy and safe topical MTX for psoriasis has nearly been attained. This review examined the development, anti-psoriatic efficacy and adverse effects of topical forms of MTX (plain MTX; MTX with chemical enhancer; MTX using nanotechnology; MTX with protein transduction domains; MTX with liquid crystalline systems; and MTX with physical enhancer/laser) and intralesional MTX in psoriasis patients and psoriasis-induced animals. The efficacy of topical MTX varied with the drug delivery technology employed. Nevertheless, the overall safety profile of the topical forms was favourable. A 25 mg/mL MTX solution injected intralesionally at the nail matrix worked well for nail psoriasis recalcitrant to topical treatment. To improve the standard of care for patients with psoriasis, randomized controlled trials that establish the most effective MTX-delivery system are needed.

Abstract
BACKGROUND Men who have sex with men (MSM) are a key HIV target population in Thailand. An important subgroup is men who have sex with men and women (MSMW) as they can sexually transmit infections between individuals with different gender identities. This study compared the sexually transmitted infection risk behavior of different types of men in Thailand. METHODS We retrospectively reviewed the medical records of 839 consecutive male patients who visited an STI clinic in Bangkok, Thailand, between 2014 and 2020. RESULTS Men who have sex with women only (MSWO) predominated (58.0%), followed by men who have sex with men only (MSMO, 32.2%) and MSMW (9.8%). MSMW and MSMO shared similar sexual risk behaviors, such as significantly higher median numbers of sex partners (10 and 8, respectively) than MSWO (5; Kruskal-Wallis, p < 0.001). MSMW had the highest prevalence of concurrent sexual partnerships (91.4%), significantly different from MSWO (61.2%) and MSMO (76.7%; chi-squared, p < 0.001). HIV and syphilis prevalence was significantly higher for MSMO (48.9% and 51.1%) and MSMW (42.7% and 48.8%) than MSWO (12.3% and 20.9%; chi-squared, p < 0.001). CONCLUSIONS MSMW exhibited similar sexual risk behavior and high HIV/STI prevalence comparable to MSMO.

Abstract
BACKGROUND Formaldehyde and formaldehyde releasers (FRs) are common preservatives in cosmetics and household products. Their contact allergy trends are decreasing in Europe and America, but trend data for Asia are limited. OBJECTIVES The first objective was to determine the prevalences of and trends in contact allergies to formaldehyde and FRs. The second objective was to establish how often formaldehyde and FRs were mentioned on the labels of products sold in the Thai market. METHODS Twenty years of data on patch test results for formaldehyde and FRs were reviewed. Their frequency of mention on the labels of 5855 products was analyzed. RESULTS The trends in contact allergy to formaldehyde and FRs were decreasing. The overall prevalence of formaldehyde contact allergy was 2.5%. The most common FR to cause contact allergy was quaternium-15. Formaldehyde and FRs were identified as ingredients in 10.2% of the products surveyed. Dimethylol dimethyl hydantoin was the most common FR (5.2%). The highest use of formaldehyde and FRs (15.5%) was in hair care products. CONCLUSIONS Although contact allergy trends in Thailand were decreasing, the proportion of products with FRs remained high. Comprehensive and universal legislation is needed to control the presence of formaldehyde and FRs. This article is protected by copyright. All rights reserved.

Abstract
Psoriasis in people living with HIV (PLHIV) has been reported as having particular clinical characteristics. However, most of the source data was derived from descriptive studies in Europe and the USA. This study was conducted to compare the characteristics of psoriasis in PLHIV to general psoriasis patients. We retrospectively reviewed the records of 73 cases of psoriasis in PLHIV and of 232 general psoriasis patients who visited a psoriasis clinic in Bangkok, Thailand. Psoriasis in PLHIV predominated in males (78.1%), with an older age of onset, significantly lower rates of nail involvement and psoriatic arthritis, but higher rates of co-infectious diseases than for general psoriasis patients. A low nadir CD4 T-cell count (<100 cells/μl) and CD4 T-cell count at psoriasis diagnosis were associated with a high body surface area (BSA) involvement. The mean BSA involvement in PLHIV was 24. Although 64.4% (47/73) of the PLHIV had moderate-to-high psoriasis severity, 29.8% of those (14/47) only received topical treatment. Acitretin was the most common drug used. Other therapies were rarely used, and no biologics were administered. In conclusion, psoriasis in PLHIV has several clinical features that differ from general psoriasis. PLHIV tend to receive substandard care for psoriasis, even in upper-middle-income countries.

Abstract
BACKGROUND Taking the perspectives of patients into consideration is of the utmost importance when defining treatment goals for psoriasis. The patient-acceptable symptom state (PASS) is a dichotomised question that captures patients' perceptions of their overall health state. OBJECTIVES To evaluate PASS and determine the factors associated with a satisfactory PASS for psoriatic patients. METHODS Three questions were asked: (Q1) Considering the ways that your skin symptoms affect your functioning, is your current skin psoriasis satisfactory? (Current PASS), (Q2) Considering the ways that your psoriasis is affecting you, if you were to remain in this state for the next few months, would this be satisfactory? (Future PASS) and (Q3) If you were to remain for the rest of your life as you were during the last 48 hours, would this be satisfactory? (Lifelong PASS). Disease severity, symptoms and health-related quality of life (HRQoL) were collected. RESULTS Of 140 patients, 74.3%, 70.0% and 85.7% expressed satisfaction with their current, future and lifelong skin psoriasis conditions respectively. A satisfactory PASS was significantly associated with older and married patients; lower disease severity; fewer skin symptoms; and a higher HRQoL. A multivariate analysis revealed that the independent factors associated with a satisfactory PASS were being older than 40 years, being married, practising meditation, not having extensive lesions at sensitive areas and having a high HRQoL. CONCLUSIONS PASS is a simple and easily administered questionnaire that reflects both disease severity and HRQoL. Understanding patients' needs and satisfaction levels will result in better care for psoriatic patients than otherwise.

Abstract
BACKGROUND Mediterranean diets have been reported to improve psoriasis. Asian food has a unique character and differs from Mediterranean diets. METHODS This study compared the dietary intake of psoriatic patients and individuals without psoriasis, and investigated the association between diet and psoriasis severity. Data were collected on the frequency of consumption of Mediterranean and Asian diets. RESULTS One-hundred psoriatic patients and 100 individuals (age- and sex-matched controls) was conducted. In the case of the anti-inflammatory diets, the psoriatic patients consumed significantly less olive oil, berry fruits, fish, seafood, tree nuts, and eggs than the controls. As to the pro-inflammatory diets, greater quantities of dairy products and soft drinks were consumed by the psoriatic patients than the controls. Regarding Asian food, the patients consumed significantly less pickled foods and brown rice/Riceberry (a rice variety), but more coconut milk, than the controls. In terms of psoriasis severity, the patients with lower severities consumed significantly more vegetables; in contrast, a higher consumption of red meat, belly meat, and instant noodles was associated with greater psoriasis severities. CONCLUSIONS Our study adds further information on the role of diets-especially Asian diets-and psoriasis. These data should help patients and clinicians to focus more clearly on diet management.

Abstract
Background The Vitiligo Extent Score (VES) and Self-Assessment Vitiligo Extent Score (SA-VES) have not been formally validated in Thai population. Objective To evaluate reliability, validity and feasibility of the VES and SA-VES in Thai vitiligo patients. Methods Vitiligo lesions from 100 patients were evaluated by 2 independent dermatologists using VES and Vitiligo Area Scoring Index (VASI). Reliability was assessed by comparing VES scores between physicians. Validity was determined by comparison among the VES, VASI, and SA-VES instruments. Patients scored their vitiligo severity using the SA-VES. Results The reliability of the VES was excellent (inter-rater reliability: 0.997, 95% confidence interval: 0.995–0.998). There was very strong correlation between the VES and VASI (r=0.976, p<0.001), and strong correlation between the VES and SA-VES (r=0.890, p<0.001), and between the VASI and SA-VES (r=0.866, p<0.001). Moderate correlation among the VES, VASI, and SA-VES was observed in patients with segmental or <1% body surface area (BSA) vitiligo. Ninety-five percent of patients rated the SA-VES as easy to moderately easy. Conclusion The VES has reliability and validity comparable to that of the VASI. The SA-VES is an user-friendly instrument that correlated well with physicians’ scoring methods in patients with non-segmental or >1% BSA vitiligo.

Abstract
Objective: This research aim to compare (1) the sensitivities and specificities of Tzanck smears and indirect immunofluorescence assays (IFA) for cutaneous HSV and VZV infections in real-life settings; and (2) the detection rates of the tests for various patient types and lesion morphologies.Materials and Methods: This retrospective study reviewed 440 and 172 samples from patients with clinically suspicious cutaneous HSV and VZV infections, respectively. All patients underwent a Tzanck smear and IFA. The gold standard for the study was agreement of pre- and post-diagnostic coding (determined by a dermatologist) for cutaneous HSV and VZV infections.Results: For HSV infections, the respective sensitivity and specificity of Tzanck smears were 32.8% and 96.6%, whereas those for IFA were 60.7% and 100%. As to VZV infections, the sensitivity and specificity of Tzanck smears were 54.3% and 97.8%, respectively, while the corresponding IFA values were 71.7% and 100%. According to disease characteristics and lesion morphologies, the detection ability of cutaneous HSV by IFA was substantially higher than Tzanck smear especially in immunosuppressed condition. Tzanck smears and IFA demonstrated no statistical difference for early-onset ( 3 days) VZV infections.Conclusion: Tzanck smears and IFA had higher sensitivities for detecting VZV than HSV infections. IFA testing in suspected cutaneous HSV patients with immunosuppressed conditions should be recommended. Despite the overall sensitivity and specificity of IFA being greater than those for Tzanck smears especially in HSV infections, the latter test is a comparable option for early-onset VZV infections.

Abstract
Objective: To systemically summarize and meta-analyze the risk of dementia in psoriasis patients.
Methods: A systematic review was performed in two databases (EMBASE and MEDLINE). The eligible studies had to be a cohort study or a cross-sectional study that compared either the prevalence or incidence of dementia in patients with psoriasis, versus individuals without psoriasis.
Results: Of 791 retrieved articles, seven studies met the inclusion criteria and were included into the meta-analysis. The risk of incident and prevalent dementia were significantly higher in patients with psoriasis, with a pooled risk ratio of 1.16 (95% CI: 1.02-1.33; I2 96%) and 1.36 (95% CI: 1.07-1.72; I2 10%), respectively.
Conclusions: This study revealed a slight increase in both the incidence and prevalence of dementia in psoriasis patients. However, dermatologists should carefully observe and periodically screen psoriasis patients for this comorbidity, especially among those who have symptoms and signs of cognitive impairment.

Abstract
BACKGROUND As several reports have raised a variety of environmental, health, and safety issues related to ultraviolet (UV) filters, it is crucial to understand the trends in the exposure of the population to UV filters. OBJECTIVE To determine the frequency of UV filter usage in sunscreens and other cosmetic products in Thai market. METHODS We surveyed the UV filter labelling on sunscreens and cosmetic products sold in the Thai market. In all, 312 sunscreens and 1350 other cosmetic products were investigated. RESULTS Titanium dioxide was the most frequently used UV filter in both sunscreens (66.7%) and other cosmetic products (68.4%). Ethylhexyl methoxycinnamate was the most common organic UVB filter, whereas butyl methoxydibenzoylmethane was the most common organic UVA filter. In sunscreens aimed at children, bis-ethylhexyloxyphenol methoxyphenyl triazine was the most commonly used UV filter. The most frequent co-occurrence of UV filters was titanium dioxide and ethylhexyl methoxycinnamate. CONCLUSIONS Titanium dioxide was the most commonly used UV filter, which differs from the findings of previous surveys. Knowing the availability and frequency of each UV filter provides valuable information about consumer exposure levels, facilitates refinements of the allergen series in patch testing, and enhances the monitoring of adverse effects of UV filters.

Abstract
Continuously updated information is helpful for evaluating the safety of long-term systemic drug use in psoriasis patients with concomitant hepatitis B virus (HBV) infection. To investigate the impact of long-term systemic treatment for psoriasis on liver disease in psoriasis patients with HBV infection. Data of patients during 10-year period were recorded and analyzed. Sixty-six patients (46 males and 20 females) with a mean age of 58.5 ± 13.1 years were recruited. Our study estimated that the 5-year cumulative risks of developing cirrhosis and HCC were 30% and 5%, respectively, in patients receiving systemic treatments for psoriasis. Risks of cirrhosis and HCC were not significantly different between systemic and topical treatment groups. Thirty patients were prescribed systemic treatments (acitretin, methotrexate, ciclosporin, and anti-tumor necrosis factors). Three HBsAg+ patients developed viral reactivation (two patients with methotrexate and one patient with ciclosporin). The effects of systemic treatments for psoriasis on liver outcome in patients with coexisting HBV infection are needed to be determined. HBsAg+ patients are more likely to develop viral reactivation during systemic treatment for psoriasis than HBsAg- patients. Monitoring of liver enzymes and HBV DNA every 3 months is recommended during treatment and for 6 to 12 months after drug discontinuation.

Abstract
BACKGROUND Photoallergic contact dermatitis is one of the important parts of photodermatoses. The investigation of choice is photopatch testing. However, reports with photopatch test results from Asian countries are scarce. The objective of this study was to determine the prevalence of positive photopatch test reactions and to ascertain the common photoallergens among Thai patients during 1998-2018. METHODS We retrospectively reviewed the records of 339 patients who were clinically suspected of having photoallergic contact dermatitis and had undergone photopatch testing. RESULTS A total of 44 photoallergic contact reactions in 38 patients (11.2%) were found. The positive photoallergic reactions were mainly found with organic ultraviolet filters and fragrances. CONCLUSIONS Organic ultraviolet filter chemicals especially benzophenone-3 and fragrances were found to have a high prevalence of photoallergic contact reactions. Monitoring of the photoallergens employed in photopatch tests should be conducted periodically to provide the best patient care.

Abstract
BACKGROUND Pediatric allergic contact dermatitis is increasing. The patch test allergens included in pediatric baseline series vary globally. The worldwide prevalence of pediatric reactions to allergens needs clarification. OBJECTIVES Identify the prevalence, associated factors, and culprit allergens for contact allergy among patch-tested Thai children, and compare with those for adults. METHODS Baseline series patch test results from 2010-2019 were collected for patients younger than 18 years of age. As a control group, sex-matched adult patients were randomly selected. The results and characteristics of the two groups were compared. RESULTS The median age of 112 patch tested pediatric patients was 16 (range 2-17) years. Of the children, 35.5% had at least one positive reaction, significantly less than the 56.6% for adults. The five most common pediatric allergens were nickel sulfate (12.1%), potassium dichromate (8.0%), methylisothiazolinone (7.1%), fragrance mix II (6.0%), and carba mix (5.4%). Although similar, the 10 most common allergens of the groups differed in order. Positive reactions to cosmetic allergens were significantly less frequent among the children. Many allergens remained entirely negative. CONCLUSIONS The prevalence of positive reactions was lower in children, varying by population and region. The top-10 pediatric and adult causative allergens were almost identical. We recommend using the same baseline patch test series for children and adults in our region.

Abstract
Background Vitiligo is a common chronic autoimmune disease that is characterized by progressive loss of skin color due to melanocyte destruction. In addition to the physical effects of vitiligo, this condition exerts adverse psychological effects and causes social stigmatization. Earlier studies reported that individuals with vitiligo suffer from poor quality of life (QoL), but data about the QoL of Thai vitiligo patients is scarce. Objective This study aimed to investigate the QoL and prevalence of depression in Thai vitiligo patients, association between QoL and depression, and factors associated with QoL and depression among Thai people with vitiligo. Methods This cross-sectional self-assessment questionnaire-based study was conducted at the phototherapy and vitiligo clinics of the Department of Dermatology, Faculty of Medicine Siriraj Hospital, Mahidol University (Bangkok, Thailand). QoL was assessed using the Dermatology Life Quality Index (DLQI) questionnaire, and depression was evaluated via the Patient Health Questionnaire (PHQ-9). Results Among the 104 vitiligo patients that were recruited, the mean DLQI score was 7.46, and the prevalence of depression (PHQ-9 ≥9) was 13.5%. Factors significantly associated with a higher mean DLQI score were skin phototype IV compared to phototype III, active disease, new lesions within the last three months, lesions involving upper extremities, and PHQ-9 ≥9 (p<0.05). Moderate correlation was found between DLQI score and PHQ-9 score (Pearson’s correlation coefficient: 0.524, p<0.001). Factors significantly associated with depression were working status and developing new lesions within the last three months (p<0.05). Patients with new lesions were 4.12 times more likely to be depressed than those without new lesions (OR: 4.12, 95%CI: 1.20–14.16; p=0.025). Conclusion Developing new lesions, active disease, dark skin phototype (IV), and lesion on upper extremity had significant adverse effects on QoL. Vitiligo patients who were employed and who had new vitiligo lesions are significantly more likely to be depressed.

Abstract
BACKGROUND Methotrexate (MTX) is a mainstay drug in the treatment of psoriatic and rheumatologic conditions. Subcutaneous MTX has become a feasible treatment alternative with the development of prefilled syringes or autoinjectors containing MTX solution that can be self-administered by the patient at home. However, MTX prefilled auto-injector pens are still not available in some countries. OBJECTIVE This study aimed to investigate the stability and sterility of 25 mg/mL MTX solution in a disposable plastic syringe over a 12-week period under light protection at temperatures of 4 °C, 25 °C, and 37 °C. METHODS This study was conducted during November 2019 to February 2020 at the Faculty of Medicine Siriraj Hospital, Mahidol University. Stability was evaluated using ultra-high-performance liquid chromatography technique, and sterility was assessed by cultures for bacterial and fungal contamination. RESULTS Our results revealed that patient-ready syringes containing 25 mg/mL MTX solution can be prepared in advance and kept for up to 12 weeks under light protection, and they can be kept at temperatures ranging from 4 to 37 °C. CONCLUSION This system for delivering MTX to patients that are refractory to or intolerant of oral MTX via a self-administered pre-filled syringe is both efficient and easy to implement in care settings where commercially alternatives are not yet available.

Abstract
BACKGROUND Narrowband UVB (NBUVB) phototherapy is the cornerstone treatment for vitiligo. Before its initiation, some experts recommend antinuclear antibody (ANA) screening out of concern for either photosensitivity to NBUVB or autoimmune disease exacerbation during treatment. As vitiligo is considered an autoimmune disorder, ANAs can be positively found in the disease without any clinical importance. The necessity for ANA investigations for pre-phototherapy vitiligo patients is therefore questioned. METHODS We conducted a retrospective study to investigate vitiligo patients who had been checked for ANA before commencing NBUVB phototherapy. Demographic data-including vitiligo type and age of onset-were collected. Samples of ANA, anti-thyroglobulin, and anti-thyroid peroxidase were obtained. The phototherapy treatment protocol and cutaneous reactions to the phototherapy were also recorded. RESULTS Among 85 Thai vitiligo patients, the ANA prevalence was 35.3%. The speckled ANA pattern was the most common, and the large majority of patients (80%) had a titer of ≤1:100. Factors associated with positive ANA were female gender and positive anti-thyroglobulin. There were no statistical differences between the phototoxic reactions or phototoxic doses of NBUVB of the ANA-positive vitiligo and ANA-negative vitiligo groups. No cases of SLE were detected in ANA-positive group. CONCLUSIONS ANA positivity was not correlated with the incidence or dose of phototoxic reaction in phototherapy treated vitiligo, and it may not a predictive factor for SLE diagnosis in vitiligo. ANA might therefore not need to be routinely checked in pre-phototherapy in vitiligo, unless there are clinical suspicions of an autoimmune disease. However, ANA might be involved in part of the cutaneous photoadaptation response to phototherapy.

Abstract
BACKGROUND There is still relatively limited data on psoriasis and hepatitis C virus (HCV) infections. OBJECTIVE This study investigated the clinical characteristics and treatment of psoriasis patients with HCV infections in real-world practice. METHODS Medical records of all psoriasis patients with HCV infections who attended the outpatient clinic at Siriraj Hospital over a 10-year period were retrospectively reviewed. RESULTS Of 34 patients, 26 and 8 patients were men and women, respectively with a mean age of 57.0 ± 8.7 (range, 42.2-77.2) years. The median age of psoriasis onset was 42.7 ± 12.7 (range, 8-67.25) years. With a median follow-up period of 13.6 years, cirrhosis and hepatocellular carcinoma were found in 67.6% and 29.4% of the patients, respectively. The interferon used for HCV treatment exacerbated the psoriasis in 20% of those patients. Conventional treatments and anti-tumor necrosis factors (anti-TNFs) were used in strict collaboration with hepatologists. No patients experienced a worsening of their HCV infection. CONCLUSION Despite a limited number of patients, a male predominance and late-onset psoriasis were frequently observed. Although, interferon therapy for HCV can exacerbate psoriasis, it is not contraindicated. All conventional treatments and anti-TNFs can be used, provided that there is strict collaboration with hepatologists.

Abstract
BACKGROUND AND OBJECTIVE Conventional treatment of vitiligo on hands and feet often produces an unsatisfactory result. Various ablative treatment methods were tried with favorable results in facial, neck, and truncal areas. The aim of this study is to evaluate the efficacy and safety of combined fractional CO2 laser, narrowband UVB (NB-UVB) phototherapy, and topical clobetasol propionate in managing stable vitiligo in difficult-to-treat areas. STUDY DESIGN A prospective randomized-intraindividual study was conducted on 27 patients with 27 pair-lesions of non-segmental vitiligo on both hands. The lesions were randomized to receive treatment with fractional CO2 laser, NB-UVB phototherapy, and 0.05% clobetasol propionate cream (Group A) or NB-UVB phototherapy and 0.05% clobetasol propionate cream (Group B). Fractional CO2 laser was performed at 1-week interval for 10 sessions. NB-UVB phototherapy was administered twice weekly for 20 sessions. Patients were evaluated 12 weeks after the last treatment. Outcome was evaluated objectively based on standard digital photographs, patient satisfaction, and adverse events. RESULTS Twenty-six patients completed the study. Six vitiligious lesions (23.1%) in group A achieved good to excellent repigmentation compared with one lesion (3.9%) in group B (P = 0.065). The overall mean improvement score was 1.35 (± 1.38) in group A and 0.50 (± 0.95) in group B (P = 0.0004). Patients' satisfaction score was significantly higher for the lesions in group A than group B. Lesions on the dorsum of the hand showed a higher response rate than those on the fingers. No serious side-effects were noted. CONCLUSION This study demonstrates that adding fractional CO2 laser treatment to NB-UVB phototherapy and topical steroids improves the repigmentation rate of vitiliginous lesions on hands in some patients. This technique may be offered to vitiligo patients who are unresponsive to other treatments.

Abstract
Chrysosporium is a large genus of saprophytic fungi that is commonly found in the soil. Infection caused by this organism is rare in humans and typically occurs in immunocompromised patients. Primary cutaneous Chrysosporium infection is relatively rare and has been reported in a heart transplant patient. The prognosis is usually favorable, but very poor in the setting of persistent profound immunosuppression. We herein report a case of primary cutaneous Chrysosporium infection following ear piercing in an immunocompetent patient. It is important for clinicians to consider this condition in patients with slow-onset skin and soft tissue infection following cutaneous injury, even in an immunocompetent setting.
