Unveiling the potential: Enhancing caregiver knowledge through video education to address topical corticosteroid concerns in children with eczematous dermatitis.

BACKGROUND: Concerns about the use of topical corticosteroids (TCS) in pediatric eczematous dermatitis management often hinder effective treatment. Limited data exist regarding the prevalence of these concerns and the effectiveness of interventions. This study aimed to assess the prevalence of TCS concerns among caregivers and determine the effectiveness of video education in mitigating these concerns. METHODS: A single-center prospective study was conducted from 2022 to 2023, involving caregivers of children under 18 years with eczematous dermatitis. Baseline and post-intervention questionnaires were administered after a 4-week period. Caregivers received video education on TCS use, and the TOPICOP score was evaluated before and after viewing the video. RESULTS: The study included 150 caregivers, 85.3% female and 74% had a child with atopic dermatitis. The prevalence of TCS concerns among Thai caregivers was 62%. Following video education, the prevalence of TCS concerns significantly decreased to 10.7%. Mean belief score decreased from 43.81 ± 13.45 to 31.85 ± 16.56, mean worry score decreased from 56.22 ± 18.27 to 40.41 ± 18.55 and mean total TOPICOP score decreased from 50.02 ± 12.65 to 36.13 ± 13.52 (p-value <.001). The intervention also resulted in reduced disease exacerbations, duration of the rash, and duration of TCS use. The optimal TOPICOP cut-off score to predict TCS concerns was identified as 43.06. CONCLUSION: Video education effectively alleviated TCS concerns among caregivers, addressing beliefs, worries, disease exacerbations, and side effects. Integration of this intervention into the management of pediatric eczematous dermatitis can yield optimal outcomes.

Cost and effectiveness comparison of sirolimus versus standard treatment in Kasabach-Merritt phenomenon: a real-world evidence study in Thailand.

The conventional treatment of Kasabach-Merritt Phenomenon (KMP) consists of corticosteroids with vincristine/vinblastine or others. The aim of the study is to compare the first-year direct costs and effectiveness between sirolimus and conventional treatment. A retrospective case-control study of KMP patients was conducted at a mean age of 9 months (1 day to 12 years) between 2000 and 2022 from four tertiary centers in Thailand. The direct costs, hematologic and clinical complete response (HCR, CCR), hospitalization, length of stay, and complications were compared. Of 29 patients, 13 underwent sirolimus (four upfront and nine were refractory to the conventional). The first-year total cost had no statistically significant difference between sirolimus VS conventional treatment (8,852.63 VS 9,083.56 USD: p value: 0.94). The therapeutics achievement was the same in both HCR (244.75 VS 168.94 days; p value: 0.60) and CCR (419.77 VS 399.87 days; p value: 0.90). The subgroup analysis of the first-line sirolimus (n = 4) compared with the conventional (n = 25) showed a more reduced total cost (4,907.84 VS 9,664.05 USD; p value: 0.26) rendered net total cost of -4,756.21 USD per patient (cost saving). A more significant contrast of therapeutic achievement by reduction of both HCR (11.67 VS 224.20 days; p value: 0.36) and CCR (38.50 VS 470.88 days; p value: 0.04) was shown. The sirolimus had no difference in hospitalization, length of stay, and complications. Even though, it was unable to identify significant differences in cost-effectiveness. Sirolimus is suitable for all patients who have diagnosis of KMP either for rescue therapy or first-line treatment.

Topical corticosteroid phobia in adolescents with eczema and caregivers of children and adolescents with eczema: A cross-sectional survey.

Steroid phobia is an increasing phenomenon that affects treatment adherence. The purpose of this study was to assess the prevalence and associated factors of steroid phobia among adolescents with eczema and the caregivers of children and adolescents with eczema by using questionnaires and TOPICOP© scale. The prevalence of steroid phobia is approximately 12% and 37% in the adolescent and caregiver groups, respectively. Caregivers who obtained information about topical corticosteroid (TCS) from dermatologists and whose children had fewer number of flares, demonstrated less concern about using TCS.

Dermatologic manifestations in pediatric patients after liver and HSCT: A 20-year retrospective cohort study.

LT and HSCT are now potentially curative treatments for many medical conditions. Dermatologic manifestations are one of the sequelae after transplantation. To study the prevalence and associated risk factors of dermatologic manifestations after pediatric LT and HSCT. A 20-year retrospective cohort study was conducted in children, aged ≤15 years, who received LT or HSCT from January 1, 1997, to December 31, 2017. Medical records were reviewed for data collection until December 31, 2018. A total of 70 LT and 51 HSCT recipients were included. The percentages of overall dermatologic manifestations after LT and HSCT were 64.3% and 64.7%, respectively. Viral infection was the most common manifestation in both groups, with mucocutaneous HSV infection as the most prevalent. One HSCT recipient developed leukemia cutis. GVHD was revealed in 27.5% of HSCT recipients. Impetigo and xerosis were significantly observed in patients using azathioprine and prednisolone. Approximately two-thirds of pediatric LT and HSCT recipients experienced dermatologic manifestations, potentially associated with immunosuppressive agents. Thus, regular skin examination and optimized immunosuppression would be beneficial in these recipients.

Subcutaneous Panniculitis-like T-Cell Lymphoma With Hemophagocytic Lymphohistiocytosis Syndrome in Children and Its Essential Role of HAVCR2 Gene Mutation Analysis.

BACKGROUND: We identified 3 adolescents with alpha-beta subtype subcutaneous panniculitis-like T-cell lymphoma. CASE PRESENTATION: Three patients presented with prolonged fever, abnormal skin lesions, and cytopenia described in the context. All had the same disease entity, which showed the prolonged duration of B systemic symptoms till diagnosis, difficulty to distinguish from autoimmune diseases, presence of hemophagocytic lymphohistiocytosis syndrome, good response, and remained on long-term remission with nonchemotherapy treatment, which included oral corticosteroid and cyclosporin. CONCLUSIONS: Although diagnosis can only be "highly suspected" with pathologic review, some cases may need multiple serial skin biopsy to clarify diagnosis because of the discrete distribution of specific histology. T-cell receptor gene rearrangement, which demonstrates a monoclonal pattern of alpha and beta chain gene, is the essential requirement for specific diagnosis. The role of molecular analysis by identification of germline hepatitis A virus cellular receptor 2 (HAVCR2) gene mutation can be much valuable in classifying susceptible patients.

Clinical practice guidelines for the diagnosis and management of atopic dermatitis.

Atopic dermatitis (AD), a chronic, relapsing dermatitis, is characterized by dry and pruritus skin in patients with a personal or family history of atopy. It affects up to 20% of children and 1-3% of adults in most countries worldwide, and leads to significant treatment costs and morbidity. These guidelines are developed in accordance with evidence-based publications and expert opinions. Following simple algorithms, the guidelines aim to assist adult and pediatric physicians in the better care of patients with AD. As with other diseases, there have been several diagnosis criteria proposed over time. Nonetheless, the classical Hanifin and Rajka criterion with no pathognomonic laboratory biomarkers is still the most widely used worldwide for the diagnosis of AD. The management of AD must be considered case by case to provide suitable care for each patient. Basic therapy is focused on avoiding specific/unspecific provoking factors and hydrating skin. Topical anti-inflammatory treatments such as glucocorticoids and calcineurin inhibitors are suggested for disease flare, and proactive therapy is best for long-term control. Other therapies, including antimicrobial agents, systemic antihistamines, systemic anti-inflammatory agents, immunotherapy, phototherapy, and psychotherapy, are reviewed in these guidelines. Crisaborole, a new topical phosphodiesterase 4 inhibitor, can be used twice daily in AD patients over three months old. Dupilumab, a biological drug for patients with moderate-to-severe AD, may be considered in patients with no improvement from other systemic treatments.

Sun protection behavior and knowledge of patients attending laser clinic to prevent adverse events of laser: A cross-sectional, single-center, tertiary care study.

BACKGROUND: Limited data of sun protection knowledge in laser treatment patients exists therefore, preventative information should be provided by dermatologists to minimize harmful effects. OBJECTIVE: To assess sun protection knowledge-behavior and knowledge to prevent adverse events from laser therapy among patients who visited a laser clinic at a tertiary university hospital in Bangkok, Thailand. METHODS: This is a self-reported questionnaire, cross-sectional survey. All participants from the Laser Clinic in KCMH were recruited into the study. RESULTS: A Total of 385 patients were enrolled into the study; 80.5% female participants. Patients who never received laser treatment significantly lacked proper sun protection knowledge to prevent adverse events of lasers when compared to those who previous received laser treatments regarding the application of sunscreen after laser treatment (56.6% vs 17.4%, P < .001), consistent application of sunscreen 4-6 weeks prior to receiving laser treatment (60.5% vs 18.9%, P < .001), application of topical corticosteroid after laser (67.1% vs 54.1%, P = .048), and sun protection in the post laser area (41.9% vs 20.4%, P < .001). CONCLUSION: The attitude and knowledge of sun protection to prevent adverse events were significantly different among the group of educational levels and previous history of laser treatment.

Nail Scabies: An Unusual Presentation Often Overlooked and Mistreated.

Nail scabies is an interesting clinical presentation of scabies. Although it is usually found concomitant with characteristic dermatologic manifestations, it may present as an isolated finding in the immunocompromised host. This condition is commonly mistaken with other diseases such as nail dystrophy, nail psoriasis and onychomycosis. We report two cases of unusual nail presentations that provide clues to diagnosis. Also, literature on unusual nail and dermatologic presentations was reviewed to recognize dermatologist consideration for appropriate treatment options.

Clinical practice guideline for diagnosis and management of urticaria.

Urticaria is a common skin condition that can compromise quality of life and may affect individual performance at work or school. Remission is common in majority of patients with acute spontaneous urticaria (ASU); however, in chronic cases, less than 50% had remission. Angioedema either alone or with urticaria is associated with a much lower remission rate. Proper investigation and treatment is thus required. This guideline, a joint development of the Dermatological Society of Thailand, the Allergy, Asthma, and Immunology Association of Thailand and the Pediatric Dermatological Society of Thailand, is graded and recommended based on published evidence and expert opinion. With simple algorithms, it is aimed to help guiding both adult and pediatric physicians to better managing patients who have urticaria with/without angioedema. Like other recent guideline, urticaria is classified into spontaneous versus inducible types. Patients present with angioedema or angioedema alone, drug association should be excluded, acetyl esterase inhibitors (ACEIs) and non-steroidal anti-inflammatory drugs (NSAIDs) in particular. Routine laboratory investigation is not cost-effective in chronic spontaneous urticaria (CSU), unless patients have clinical suggesting autoimmune diseases. Non-sedating H1-antihistamine is the first-line treatment for 2-4 weeks; if urticaria was not controlled, increasing the dose up to 4 times is recommended. Sedating first-generation antihistamines have not been proven more advantage than non-sedating antihistamines. The only strong evidence-based alternative regimen for CSU is an anti-IgE: omalizumab; due to very high cost it however might not be accessible in low-middle income countries. Non-pharmacotherapeutic means to minimize hyper-responsive skin are also important and recommended, such as prevention skin from drying, avoidance of hot shower, scrubbing, and excessive sun exposure.

A Comparative Study of 3 Different Methods of Temperature Measurement in Children.

BACKGROUND: The accuracy of body temperature measurement is very important in children. The accuracy and reliability of the forehead skin thermometer (FST) and infrared tympanic thermometer (TT) are inconclusive. OBJECTIVES: To determine: 1) the mean difference, agreement, and accuracy of body temperature detected in children by FST and ITT, as compared with the gold standard rectal mercury-in-glass thermometer (RMT); and, 2) the cut-off level for FST and ITT in the detection of fever MATERIAL AND METHOD: Children ≤ 2 years old with the chief complaint of "fever" were recruited for this study. Body temperature (BT) was measured by 3 different methods, including FST 5 times; ITT 3 times; and, RMT, 1 time, for each patient. Each measurement method was performed by 3 well-trained staff members, all of whom were blinded to the recorded data of the other methods. The mean difference in body temperature, agreement by Bland-Altman method, and the verified performance of FST and ITT by diagnostic test were assessed. RESULTS: A total 312 children were recruited. Body temperatures measured by FST and ITT were lower than those measured by RMT, with a mean difference of 1.04°C (p < 0.001) and 1.03°C (p < 0.001), respectively. In subgroup analysis by levels of fever the mean differences between rectal temperature and both forehead and ear temperature were statistically significantly different (p < 0.001) for all levels of fever. Regarding the diagnostic test to verify performance, the data revealed the most practical cut-off point to be 37.0°C for both FST and ITT as compared to the gold standard RMT. CONCLUSION: Both FST and ITT were found to be accurate temperature screening methods for daily clinical use. However, the cut-off points to detect fever should be lowered to 37.0°C to be consistent with gold standard measurement.

The natural course of childhood atopic dermatitis: a retrospective cohort study.

BACKGROUND: Atopic dermatitis (AD) is generally considered to be the initial step of the so-called atopic march, which following steps are allergic rhinitis (AR) and asthma. There are few data about the progression of AD, including factors associated with the remission of AD in Asians and further research is needed. OBJECTIVE: To study the progression and factors associated with the remission of childhood AD diagnosed by pediatric dermatologists. METHODS: This study included 303 AD patients who visited the pediatric dermatology unit at King Chulalongkorn Memorial Hospital, Thailand, between 2002 and 2010. An interview, performed by a physician via telephone using a preformed questionnaire, was completed for 205 children. RESULTS: A total of 205 children were observed, with a median observation time of 5.2 (3.5-8.0) years, and an initial AD severity score of mild (61.0%), moderate (29.3%) and severe (9.7%). The prevalence of AD during the first two years of life was 64.4%. AD completely disappeared in 102 cases (49.8%) by the median age of 3.5 (1.5-7.8) years. Early onset and severity of AD were major determinant of prognosis. The prevalence of AR and asthma was 36.6%, and 9.3%, respectively. The risk factors associated with respiratory allergy were the onset of AD after aged two years, a family history of atopy, increased serum IgE level, and sensitization to inhalant allergens. CONCLUSIONS: Half of AD had completely disappeared at preschool age. Good prognosis was mostly determined by early onset AD and mild severity. Late onset, family history of atopy and increased serum IgE level are associated with respiratory allergy.

A 595 nm pulsed dye laser as an adjuvant intervention for post-comedone extraction erythema and comedone reduction: A randomized, split-face controlled trial.

BACKGROUND: Comedone extraction provides greater satisfaction for acne treatment than conventional treatment alone; however, post-comedone extraction erythema (PCEE) remains a concern for patients. OBJECTIVES: To evaluate the efficacy of pulsed-dye laser (PDL) in PCEE and comedone reduction. METHODS: Mild-to-moderate acne patients were randomly allocated in split-face fashion. Three comedones were extracted on each facial side. On the PDL-treated side, 595-nm PDL was delivered to the entire side with an additional shot on three comedone-extracted sites. Erythema index (EI) and total acne lesion counts (TALC) were evaluated at baseline, week 2 and 4. The comprehensive acne severity scale (CASS) was assessed by three blinded independent pediatric dermatologists. Participant satisfaction surveys were completed at the end of the study. RESULTS: Thirty-five participants (age 12.9-24.2 years) showed no differences in the EI and TALC at baseline on both sides. At weeks 2 and 4, the EI on the PDL-treated side was significantly lower (p < 0.001) with a greater EI reduction (p < 0.001) when compared to the control side regardless of gender and menstruation. There was significantly lower TALC on the PDL-treated side at week 2 (p < 0.001) and week 4 (p = 0.02). No complications were noted with high participant satisfaction reported (median 8; IQR 7-9). PDL remained significantly associated with EI improvements after controlling for gender, menstruation cycle, and examination stress. CONCLUSION: PDL can be an adjunctive intervention for the treatment of PCEE and comedone reduction due to its effectiveness and high participant satisfaction.

Pediatric drug reaction with eosinophilia and systemic symptoms: A 12-year retrospective study in a tertiary center.

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is a rare and severe adverse drug reaction involving multiple organs. Data on DRESS syndrome among children are currently limited. The purpose of this study was to determine the clinical features, causative drugs, systemic organ involvement, laboratory findings, disease severity score, and treatment outcomes in pediatric DRESS patients. The medical records of all pediatric DRESS patients, based on the RegiSCAR diagnostic criteria and admitted to King Chulalongkorn Memorial Hospital, Bangkok, Thailand from January 2010 to December 2021, were reviewed. Twenty-two cases were identified (males 54.5%) with a median age of 9.5 years. Anticonvulsants (54.5%) and antibiotics (27.3%) were the leading culprit drugs. Skin rash was reported in all cases, followed closely by liver involvement (95.5%). Eosinophilia and atypical lymphocytosis were identified in 54.5% and 31.8% of cases, respectively. The median latency period was 17.5 days. Liver enzyme elevation was detected at an average onset of 20.0 days and hepatocellular type was the most common pattern of liver injury. Nineteen patients (86.4%) were treated with systemic corticosteroids with prednisolone being the most prescribed medication. One case developed Graves' disease after DRESS and multiple relapses of DRESS. One case (4.5%) died due to refractory status epilepticus that was unrelated to DRESS. Anticonvulsants were the major cause of DRESS in pediatric patients. High suspicion for DRESS is crucial in patients receiving these drugs and presenting with fever, rash, and internal organ involvement.

Management of Moderate-to-Severe Atopic Dermatitis in Adults: A Cross-Sectional Survey of Dermatologists Within the Asia-Pacific Region.

INTRODUCTION: Limited evidence is available on real-world management of atopic dermatitis (AD) among Asian adults. This cross-sectional study aimed to assess current approaches in AD diagnosis and management in Asia. METHODS: Practising dermatologists regularly treating patients with moderate-to-severe AD were recruited from eight Asia-Pacific territories, namely Mainland China, Hong Kong, India, Japan, Singapore, South Korea, Taiwan, and Thailand. A survey was administered to eligible dermatologists after screening and taking informed consent. Data from fully completed submissions were analysed using descriptive statistics. The study was reviewed by the institutional review board in each territory. RESULTS: Data from 271 dermatologists were included for analysis. About one-third (31.7%) reported that they referred to the Hanifin and Rajka criteria during diagnosis. The majority of dermatologists used clinical impression when assessing AD severity and treatment response. Reduction of eczema and pruritus was the primary treatment objective when managing both acute (98.1%) and chronic (69.1%) AD. More than half of dermatologists preferred adding systemic anti-inflammatory medication for patients who did not respond to maximized topical treatment, while 43.6% would switch to another systemic medication for those failing to respond to maximized systemic treatment. Topical corticosteroids were frequently selected by dermatologists. For systemic therapies, oral corticosteroids were most frequently used, followed by cyclosporin and dupilumab. Narrow-band ultraviolet B was the most common phototherapy reported (84.9%). There was considerable variation in estimated average and maximum durations of therapies used to treat AD. CONCLUSION: This study has provided insights on the real-world management of moderate-to-severe AD in the Asia-Pacific region. The diverse approaches in diagnosis and treatment highlight the multifactorial nature of AD, reliance on clinical judgement, and importance of personalized care. To improve outcomes in patients with AD, it will be crucial to develop biomarkers for diagnosis, reduce subjectivity in assessment, as well as promote access to newer and effective therapies.

Bridging the Gap: Comparing Patient-Clinician Views on Treatment Goals and Communication in the Management of Atopic Dermatitis Within the Asia-Pacific Region.

INTRODUCTION: It remains unclear how patients with atopic dermatitis (AD) and clinicians perceive the level of patient-clinician communication and if there could be potential lapses. This cross-sectional study aims to compare perspectives between patients with AD and dermatologists regarding communication and treatment expectations in Asia. METHODS: Moderate-to-severe patients with AD and practicing dermatologists were recruited from eight Asia-Pacific territories, including Mainland China, Hong Kong, India, Japan, Singapore, South Korea, Taiwan, and Thailand. Patients and dermatologists completed separate surveys designed to elicit their expectations regarding AD management, and their perceived level of patient-clinician communication. Patients were also asked about their treatment satisfaction and whether they prefer additional treatment beyond what was prescribed. Demographic information and responses were analyzed using descriptive statistics. The study was reviewed by the institutional review board in each territory, and all participants provided informed consent. RESULTS: A total of 1103 patients and 271 dermatologists completed the surveys. Both patients and dermatologists were largely aligned in their top treatment goals in AD management. However, greater proportions of patients prioritized the prevention of exacerbation (78.0% versus 47.2%), minimization of treatment adverse effects (46.4% versus 9.1%), and improvement in mental health (16.0% versus 4.9%), compared with dermatologists. Although patient-clinician communication was observed to be generally good, 10.9% of patients reported dissatisfaction with communication in AD management. The majority of patients were either "very satisfied" or "satisfied" with their latest acute AD treatment, but 65.5% of patients still desired additional treatment. CONCLUSIONS: This multinational study has provided insights on the perspectives of Asian patients and dermatologists in treatment goals, AD management, and communication. In general, both patients and dermatologists were aligned in treatment goals and there was satisfactory patient-clinician communication in most aspects. However, potential areas of improvement have been identified to further enhance patient-centered care.

Quality of Life and Burden of Moderate-to-Severe Atopic Dermatitis in Adult Patients Within the Asia-Pacific Region: A Cross-sectional Survey.

INTRODUCTION: The burden of atopic dermatitis (AD) is significant, with a substantial impact on quality of life (QoL). This cross-sectional study aimed to ascertain the burden of AD, its impact on QoL, and associated costs. METHODS: Patients with moderate-to-severe AD were enrolled from eight territories, namely Hong Kong, India, Japan, Mainland China, Singapore, South Korea, Taiwan, and Thailand. After screening was performed and informed consent was obtained, eligible participants were asked to provide responses on their AD symptoms, severity, treatment, and out-of-pocket costs via an online survey. QoL was assessed using EQ-5D-5L and Dermatology Life Quality Index (DLQI), while productivity loss was quantified using the Work Productivity and Activity Impairment (WPAI) questionnaire. Data from completed submissions were analyzed using descriptive statistics. The study was reviewed by the institutional review board in each territory. RESULTS: Median age of enrolled patients (N = 1103) was 41.0 years (interquartile range, IQR 16.0). The majority of patients reported that their head/neck, trunk, upper limbs, and lower limbs were affected during a flare. Topical (74.2%) and oral steroids (58.7%) were frequently prescribed to manage AD. Common atopic comorbidities were allergic urticaria (64.2%), allergic rhinitis (61.8%), and allergic conjunctivitis (51.5%). Median DLQI score was 13.0 (IQR 11.0), while median EQ-5D-5L (based on China value set) score was 0.8 (IQR 0.4); 87.2% and 77.2% of patients reported pain/discomfort and anxiety/depression on the EQ-5D-5L domains, respectively. Median total annual costs associated with AD were USD 10,128.52 (IQR 12,963.26) per patient, with indirect costs being the largest component. Findings from WPAI indicated that presenteeism is a major contributor to productivity loss. CONCLUSION: This multinational survey study showed that AD is associated with substantial QoL impairment and economic burden among Asian adult patients with moderate-to-severe AD. To alleviate burden of AD, clinicians should be more proactive in managing other concomitant conditions including psychological issues, and advocate for increased reimbursement for AD treatments.

A prospective placebo-controlled study on the efficacy of onion extract in silicone derivative gel for the prevention of hypertrophic scar and keloid in median sternotomy wound in pediatric patients.

BACKGROUND: New topical treatments studied in adults have been published to be potentially effective in the treatment of hypertrophic scar and keloids. There is still no study in Thai children. OBJECTIVE: To study the efficacy of 10% onion extract in silicone derivative gel for the prevention of hypertrophic scar and keloid in median sternotomy wound from open heart surgery in pediatric patients. MATERIAL AND METHOD: Thirty-nine pediatric patients who had median sternotomy were recruited in this prospective randomized, double-blinded, placebo-controlled split-scar experimental study. The wound in each patient was divided into upper and lower parts, and the treatment with, either onion extract gel or placebo was randomly applied by block randomization onto each part of the wound twice daily after the seventh day postoperatively for six months. The incidence of scars, serial photographs of the wound, Vancouver Scar Scale (VSS), and adverse effect were assessed at each visit. RESULTS: Thirty patients with the mean age of 4.3 years completed the 6-month study period. Six patients (20%) in onion extract gel group had no scar compared to one patient (3.3%) in placebo group (p = 0.04). Of the 27 patients with hypertrophic scar nine were from onion extract gel group and 18 from the placebo group (p = 0.02). Keloid was not statistically significant diferent in both groups (p = 0.29). VSS was not statistically significant different in all visits. One case had a pustule on the part of the onion extract in silicone derivative application at the sixth month. CONCLUSION: Onion extract in silicone derivative gel can significantly decreased the incidence of hypertrophic scar from median sternotomy wound in pediatric patients. Keloid did not show statistically significant differences in both groups.

Randomized, double-blind, split-side, comparison study of moisturizer containing licochalcone A and 1% hydrocortisone in the treatment of childhood atopic dermatitis.

BACKGROUND: Atopic dermatitis (AD) is a common chronic inflammatory skin lesion in children. Topical corticosteroid is the mainstay of treatment. OBJECTIVE: To compare the efficacy of moisturizer containing licochalcone A (LicA) and 1% hydrocortisone for the treatment of mild to moderate childhood AD. MATERIAL AND METHOD: This was a multicenter randomized, prospective, split-side, double-blind study in 55 children between the age of three months and 14 years. Patients with AD were treated twice daily, simultaneously with either Lic A or 1% hydrocortisone on opposite sides of the lesion. The SCORAD and transepidermal water loss (TEWL) were performed at the baseline, 2-week, and 4-week visits. Lic A was used on both sides of the body for another four weeks to see the effects and TEWL. RESULTS: In a randomized period, both products were equally effective in the treatment. SCORAD decreased significantly from baseline for both treatments throughout the first four weeks (p < 0.001). There was no statistically significant difference in SCORAD between both treatments (p = 0.321 and p = 0.146 at week 2 and 4, respectively). Lic A had statistically significant decrease in TEWL (p = 0.027 and p = 0.03 at weeks 2 and 4, respectively). One patient had infection on skin lesions of both sides of the body. Forty-three patients continued to the period of using Lic A on both sides of the body. SCORAD and TEWL were comparable to the end of the randomized period and significantly lower from baseline (p < 0.001). Skin lesions flared up in three patients (7.5%). CONCLUSION: Lic A had a similar result in terms of SCORAD compared to 1% hydrocortisone for the treatment of mild and moderate AD. TEWL was significantly lower than baseline on the side that used Lic A. Continuing use of Lic A for four weeks can maintain clinical and barrier improvement.

Attitudes, knowledge, and behaviors of secondary school adolescents regarding protection from sun exposure: a survey in Bangkok, Thailand.

BACKGROUND: Sun protection behavior is a proven intervention for aging skin and skin cancer prevention, especially if training on prolonged sun exposure can be performed early in life. Despite the fact that there are several study reports from multicenters in the West, there are limited data on sun protection in tropical countries where the prevalence of sunburn as well as sun protection behavior and knowledge are low. In Bangkok, sun protection behavior among adolescents is different from the studies performed in the West. Schools are key institutions in encouraging students to prevent themselves from acquiring problems of long-time sun exposure. OBJECTIVE: To assess the amount of time exposed to the sun, sun protection behavior, attitudes, and knowledge about sun exposure protection among secondary school adolescents in Bangkok, Thailand. METHODS: This is a nonrandomized, cross-sectional survey. All students from seven secondary schools in Bangkok (public/private, male/female/coed) were recruited in to the study. RESULTS: A total of 10,387 students were enrolled in to the study; 6176 (59.5%) and 4211 (40.5%) students were from grades 7 to 9 and 10 to 12, respectively. Male students significantly lacked proper sun-protecting behaviors when compared to the female students in the use of sunscreen (9.4% vs. 28.0%, P < 0.001), staying under the shade (55.5% vs. 65.2%, P < 0.001), and use of umbrellas (5.2% vs. 12.1%, P < 0.001). Proper attitudes and sun-protecting behaviors among junior high school students were deficient when compared to high school students in the use of sunscreen (57.1% vs. 60.6%, P < 0.001), types of clothing (10.5% vs. 15.3%, P < 0.001), and hat (3.2% vs. 3.9%, P < 0.001). CONCLUSION: Sun protection behavior among adolescents in Bangkok was poor compared to Western countries. The attitudes and general knowledge about sun protection were significantly different among male and female students from grades 7 to 9 and 10 to 12. LIMITATION: The limitation of the study is the use of self-reported questionnaires in assessing sun exposure and protection.

Late sequelae of drug reaction with eosinophilia and systemic symptoms (DRESS) cause thyroid dysfunction and thyroiditis: review of literature.

Drug reaction with eosinophilia and systemic symptoms (DRESS) is one of the severe cutaneous adverse drug reactions (SCARs) with high mortality rate and variable long term sequelae, especially in thyroid dysfunction and thyroiditis. In this article, we review clinical course, culprit drugs, onset of diagnosis, and type of thyroid dysfunction in DRESS patients. There were a total of 51 cases including 12 children (aged less than 18 years old) and 39 adults from our review. The most common thyroid dysfunction was Hashimoto's thyroiditis (41/51=80.4%) including anti-thyroid antibody positive (29/51=56.9%), possible/compatible with Hashimoto's thyroiditis (12/51=23.5%) both in the children (n=12) and adult (n=39), Graves' disease/hyperthyroidism (7/51=13.7%) and non-specific hypothyroidism (3/51=5.9%), respectively. The most common culprit drugs and onset of thyroid dysfunction after DRESS diagnosis in children aged less than 18 years include antiepileptic drugs (phenytoin, phenobarbital, carbamazepine) (range 0-8 months, median 2 months) and sulfa groups (sulfasalazine, sulfamethoxazole, sulfonamide) (range 1-4 months, median 2 months). Data of prevalence, type, and clinical course of thyroid dysfunction from DRESS is important for clinicians to recognize for monitoring its sequelae and provide plans for treatment.
