ABSTRACT

Background@#Pediatric alopecia areata (AA) can affect the quality of life (QoL) of patients and their family members. Research on the QoL and burden on family members in pediatric AA is limited. @*Objective@#This nationwide multicenter questionnaire study described the QoL and burden of the family members of patients with pediatric AA. @*Methods@#This nationwide multicenter questionnaire study enrolled AA patients between the ages of 5 and 18 years from March 1, 2017 to February 28, 2018. Enrolled patients and their parents completed the modified Children’s Dermatology Life Quality Index (CDLQI) and the modified Dermatitis Family Impact (mDFI). The disease severity was measured using the Severity of Alopecia Tool (SALT) survey scores. @*Results@#A total of 268 patients with AA from 22 hospitals participated in this study. Our study found that the efficacy and satisfaction of previous treatments of AA decreased as the severity of the disease increased. The use of home-based therapies and traditional medicines increased with the increasing severity of the disease, but the efficacy felt by patients was limited. CDLQI and mDFI scores were higher in patients with extensive AA than those with mild to moderate AA. The economic and time burden of the family members also increased as the severity of the disease increased. @*Conclusion@#The severity of the AA is indirectly proportional to the QoL of patients and their family members and directly proportional to the burden. Physicians need to understand these characteristics of pediatric AA and provide appropriate intervention to patients and their family members.

ABSTRACT

Background@#In psoriasis treatment, not all body regions improve simultaneously after clinical interventions. @*Objective@#This study was aimed at evaluating clinical responses across body regions, which may differentially influence patient treatment plans. @*Methods@#This prospective, observational, and multi-center study was conducted in Koreans who adhered to ustekinumab treatment based on criteria per local label and reimbursement guidelines. A total of 581 were included in this analysis. @*Results@#The mean (±standard deviation) psoriasis area severity index (PASI) score at baseline, age, disease duration, and body surface area (%) were 18.9±9.69, 44.2±13.29 years, 11.3±9.65 years, and 27.8±17.83, respectively. Across the head and neck, upper extremities, trunk, and lower extremities, the correlation between the PASI sub-scores for the upper and lower extremities was the highest (r=0.680). The mean PASI sub-score for the lower extremities was the highest at baseline. PASI90 and PASI100 scores were the highest for the head and neck region, indicating the highest response rates, while those for the lower extremities were consistently low at all visits. @*Conclusion@#We found differences in regional ustekinumab responses, with the lower extremities being the most difficult to treat. These findings should be considered in psoriasis treatment.

ABSTRACT

Background@#Although particulate matter likely provokes inflammatory reactions in those with chronic skin disorders like atopic dermatitis, no study has examined the relationship between particulate matter and psoriasis exacerbation. @*Objective@#This study evaluated possible associations between particulate matter and hospital visits for psoriasis patients in 7 major cities in South Korea. @*Methods@#We investigated the relationship between psoriasis and particulate matter. To do this, we used psoriasis patient data from the Korean National Health Insurance Service database. In addition, PM 10 and PM 2.5 concentration data spanning a 3-year time frame were obtained from the Korea Environment Corporation. @*Results@#A pattern analysis generated by the sample cross-correlation function and time series regression showed a correlation between particulate matter concentration and the number of hospital visits by psoriasis patients. However, the prewhitening method, which minimizes the effects of other variables besides particulate matter, revealed no correlation between the two. @*Conclusion@#This study suggests that particulate matter has no impact on hospital visit frequency among psoriasis patients in South Korean urban areas.

ABSTRACT

Background@#Only a few studies have tried to assess factors relevant to the satisfaction of the participants in atopic dermatitis (AD) educational programs. More systematic modeling of this issue is needed. @*Objective@#To examine the benefit of a conjoint educational program for AD on patients and caregivers in a clinical setting. @*Methods@#In a half-day educational program called “AD school”, 831 people (493 patients and 338 family members) participated for 8 years. Various educational and entertaining programs were provided. The on-site survey was administered to measure participants’ satisfaction and perception of the benefit. We applied structural equation modeling to identify the relations among satisfaction and perception. @*Results@#A total of 209 family survey data was obtained and analyzed. The survey items were grouped into four categories. The categories were classified as individual education, group education, fun activity, and overall satisfaction (fun, benefit, intention to re-join and recommend to others). According to the model that we built, comprehensive group education was demonstrated to be the most relevant factor affecting overall satisfaction. @*Conclusion@#Our holistic approach would allow dermatologists to improve the efficacy of the conjoint educational program for AD.

ABSTRACT

An 83-year-old man presented with an intermittently bleeding fixed nodule on the left side of the chest for 2 months. Due to the clinical suspicion of metastatic cancer or a ruptured epidermal cyst, a punch biopsy was performed, which revealed granulation tissue. During surgical excision, a connection between the granulation tissue and the deeper structure was confirmed. Based on the clinicopathological findings, a cutaneous fistula was suspected;a detailed history revealed that he had experienced blunt chest trauma in a motorcycle accident 2 months before. Subsequent chest computed tomography showed soft tissue infiltration in the left sixth rib. Finally, the patient was diagnosed with a cutaneous fistula and underwent resection of the left sixth rib and costal cartilage. Cutaneous fistulae rarely occur in the chest. In cases where a recalcitrant inflammatory nodule is observed on the chest, the patient’s trauma history and ordinary medical history should be evaluated to rule out a cutaneous fistula.

ABSTRACT

Background@#Cutaneous malignant melanoma (CMM) develops mainly in the elderly, although it is often seen in young patients and in clinical practice. However, there are few studies on the clinical features of young patients with CMM in Korea. @*Objective@#To investigate the clinical characteristics of young Korean patients with CMM. @*Methods@#We retrospectively reviewed the medical records of patients with CMM between January 2009 and June 2019 and compared the clinical features of CMM in patients aged 10∼39 and 50∼79 years. @*Results@#Of the 341 patients with CMM, only 22 (6.5%) were between the age of 10∼39 and 250 (73.3%) were aged 50∼79. Acral lentiginous melanoma (ALM) was the most common clinical subtype in both groups (45.5% and 71.2%, respectively). Subungual melanoma was more common in age 10∼39 years (27.3% vs. 17.2%), whereas ALM except subungual melanoma was more common in age 50∼79 years (18.2% vs. 54.0%). Superficial spreading melanoma (31.8%) was also a significant subtype observed in age 10∼39 years (p<0.001). Frequently involved locations in age group 10∼39 were fingers (27.3%) and trunk (22.7%), but feet (40.8%) were common in age group 50∼79 (p=0.009). There were no differences in mean Breslow thickness, lymph node metastases, or staging of CMM (p>0.05). @*Conclusion@#Compared with elderly patients, CMM in patients aged 10∼39 showed differences in the location of the lesion and clinical subtype. Therefore, a misdiagnosis can be prevented when a young patient has suspected CMM on the finger or trunk.

ABSTRACT

Background@#In 2015, the Korean Atopic Dermatitis Association (KADA) working group published consensus guidelines for treating atopic dermatitis (AD). @*Objective@#We aimed to provide updated consensus recommendations for systemic treatment of AD in South Korea based on recent evidence and experience. @*Methods@#We compiled a database of references from relevant systematic reviews and guidelines on the systemic management of AD. Evidence for each statement was graded and classified based on thestrength of the recommendation. Forty-two council members from the KADA participated in three rounds of voting to establish a consensus on expert recommendations. @*Results@#We do not recommend long-term treatment with systemic steroids forpatients with moderate-to-severe AD due to the risk of adverse effects. We recommend treatment with cyclosporine or dupilumab and selective treatment with methotrexate or azathioprine for patients with moderate-to-severe AD. We suggest treatment with antihistamines as an option for alleviating clinical symptoms of AD. We recommend selective treatment with narrowband ultraviolet B for patients with chronic moderate-to-severe AD. We do not recommend treatment with oral antibiotics for patients with moderate-to-severe AD but who have no signs of infection. We did not reach a consensus on recommendations for treatment with allergen-specific immunotherapy, probiotics, evening primrose oil, orvitamin D for patients with moderate-to-severe AD. We also recommend educational interventions and counselling for patients with AD and caregivers to improve the treatment success rate. @*Conclusion@#We look forward to implementing a new and updated consensus of systemic therapy in controlling patients with moderate-to-severe AD.

ABSTRACT

BACKGROUND: Tinea capitis is a cutaneous infection of dermatophytes and predominant in children. Although tinea capitis in Korea is controlled by oral antifungal medications and concerted public health initiatives, it's still a health issue.OBJECTIVE: To investigate changes in the epidemiological and mycological characteristics of adult patients with tinea capitis in southeastern Korea.METHODS: Using medical records from Kyungpook National University Hospital and Catholic Skin Clinic from 1989 to 2018, we retrospectively investigated the epidemiological and mycological characteristics of 266 adult patients (aged over 20) with tinea capitis.RESULTS: Among total 266 patients, 239 were KOH-positive. The annual incidence of tinea capitis ranged from 3 to 18 between 1989 and 2018. Of the total, 54 (20.30%) were male and 212 (79.70%) were female. Eighty patients (30.08%) were in their seventies, the most commonly affected age group. Of the remaining, 58 (21.80%) were in their sixties, and 41 (15.41%) in eighties. Among all, 77 (28.95%) visited the hospital in summer, 72 (27.07%) in spring, 64 (24.06%) in winter, and 53 (19.92%) in fall. Dermatophytes were cultured from 171 patients. Microsporum canis was the most common dermatophyte (42.48%), while Trichophyton rubrum was the second (15.79%). Of the 266 patients, 186 (69.92%) lived in urban areas and 80 (30.08%) in rural areas.CONCLUSION: The epidemiological and mycological characteristics of adult patients with tinea capitis were different from those of children in terms of annual incidence, sex distribution, and isolated dermatophytes. These results provide useful information for the treatment and prevention of tinea capitis.

ABSTRACT

Patient education is important for successful management of atopic dermatitis; however, due to limited time and resources, patient education remains insufficient. This study aimed to investigate the current state of education provided by Korean dermatologists, pediatric allergists, and allergists to patients with atopic dermatitis. A questionnaire survey consisting of items regarding educational programs for patients with atopic dermatitis was conducted via e-mail. In total, 153 participants responded to the questionnaires, and 26.8% indicated that they have had separate educational programs. The workforce involved in the educational program included nurses, residents or fellows, dieticians, pharmacists, and clinical psychologists. Most education protocols addressed the characteristics and natural course of atopic dermatitis and environmental management. Overall, 96.7% of the participants replied that an additional charge is needed for education; moreover, additional assistance from an academic society or association, in the form of medical staff, organized data, and advertisement, is required to develop and provide a well-structured educational program. A standardized education protocol will effectively provide appropriate education for patients with atopic dermatitis. Arrangement of education fees, covered by the National Health Insurance Service, will lead to the establishment of a structured educational program and participation of an additional medical workforce.

ABSTRACT

BACKGROUND: Systemic immunomodulatory treatment is actively recommended in the treatment for moderate to severe atopic dermatitis (AD) patients. However, consensus criteria for the classification of AD severity or treatment refractoriness have not been established yet. OBJECTIVE: To establish consensus criteria on the definition of severity classification and treatment refractoriness of AD to provide a basis for proper treatment strategy. METHODS: The Korean Atopic Dermatitis Association (KADA) comprised a task force team to establish a definition of moderate to severe AD. A draft of definition of moderate to severe AD was made on the basis of evidence. The recommendation was confirmed by KADA members through a web-based survey. RESULTS: KADA approved that AD with 16≤eczema area and severity index (EASI)<23 should be basically defined as moderate AD whereas AD with EASI score ≥23 should be considered as severe AD. They agreed that it would be reasonable to raise the severity level if patient's daytime or nighttime pruritus numerical rating scale is equal to or higher than 7 (≥7) or dermatology life quality index score exceeds 10. AD patients who do not reach EASI 50 after appropriate treatment for three months should be considered as a non-responder. Patients with recurrence (EASI ≥16) within three months after cessation of treatment should be considered as a recurrent AD. CONCLUSION: KADA built a consensus of definition of moderate and severe AD and treatment-refractoriness. These guidelines are expected to help physicians determine proper treatment options in need.

ABSTRACT

BACKGROUND@#Tinea capitis is a contagious fungal infection that occurs predominantly in childhood. Although its incidence has declined, its epidemiological and mycological characteristics are continue to evolve.@*OBJECTIVE@#To assess changes in the epidemiological and mycological characteristics of tinea capitis in teenage patients in Southeastern Korea.@*METHODS@#We retrospectively investigated epidemiological and mycological characteristics of 202 teenage patients with tinea capitis who visited Kyungpook National University Hospital and the Catholic Skin Disease Clinic from 1989–2018.@*RESULTS@#Of 202 patients, 177 patients showed KOH-positivity. Dermatophytes were cultured from 157 patients. The annual incidence of tinea capitis ranged from 0 to 30 between 1989 and 2018. Of 202 patients, 153 patients (75.74%) were male and 49 patients (24.26%) were female. The ratio of male to female was 1:0.32. For seasonal distribution, 78 patients (38.61%) visited our hospital in winter, 59 patients (29.21%) visited in spring, 35 patients (17.33%) visited in fall, and 30 patients (14.85%) visited in summer. Microsporum canis was the most common dermatophyte (44.06%) isolated from tinea capitis. Trichophyton tonsurans was the second most common dermatophyte (26.73%). For inhabitancy distribution, 151 patients (74.75%) lived in urban areas and 51 (25.25%) lived in rural areas.@*CONCLUSION@#The epidemiological characteristics of teenage patients with tinea capitis were distinct from those of adults in annual incidence, sexual distribution and isolated dermatophytes. Trichophyton tonsurans was the main causative organism of tinea capitis in recent 10 years. These results are useful for the targeted treatment and prevention of tinea capitis.

ABSTRACT

Terra firma-forme dermatosis is characterized by asymptomatic dirt-like papules and plaques. It appears as dirt-like lesions, but is known to develop in persons with normal hygiene habits. Terra firma-forme dermatosis is rarely reported and has an unknown etiology. It is hypothesized to occur as a result of abnormal keratinization. Terra firma-forme dermatosis is usually detected in children and young adults. Its characteristic features include disappearance with alcohol swabbing. Thus, wiping with alcohol-soaked cotton is recommended before any other examination in cases where terra firma-forme dermatosis is suspected.

ABSTRACT

BACKGROUND: Increasing evidence suggests a pivotal role for neuronal inflammation in response to replicating varicella zoster virus in the development of postherpetic neuralgia (PHN). OBJECTIVE: In this study, we investigated the value of serum levels of various inflammatory markers in acute herpes zoster (HZ) as predictors for the development of PHN. METHODS: A total of 116 patients with acute HZ were enrolled in this study. We measured scores on the pain visual analogue scale (VAS) at baseline and at 1, 3, and 6 months after diagnosis of HZ. We defined PHN as pain greater than 1 on the VAS lasting for more than 6 months. Serum samples for laboratory assay, including complete blood count were obtained at the initial visit. Correlations between the levels of each inflammatory marker and the development of PHN were evaluated. RESULTS: Levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), lymphocyte count, and albumin showed significant correlations with development of PHN in univariate analysis. Levels of ESR, CRP, and lymphocyte count also showed significant correlations in multivariate analysis. ESR level showed stronger correlations with development of PHN than levels of CRP and lymphocyte count. CONCLUSION: In this study, we confirmed that elevated ESR was an independent and significant predictor of PHN in patients with acute HZ. To validate these results, further well-designed, randomized clinical trials are needed.

ABSTRACT

BACKGROUND: Topical tacrolimus is an effective anti-inflammatory therapy for acute and chronic states of atopic dermatitis (AD) in both adults and children. Topical tacrolimus has particular use at sensitive areas such as the face, anogenitals, and skin folds of neck and extremities. However, many AD patients also experience aggravated symptoms on trunk. OBJECTIVE: The aim of this study was to investigate the efficacy and safety of topical tacrolimus for AD patients with truncal lesions. METHODS: AD patients with truncal lesions who were aged ≥2 years were recruited from 20 centres in Korea. They received treatment with topical tacrolimus ointment twice daily during 4 weeks. The primary end point was change of the local eczema area and severity index (EASI) of the trunk from baseline to day 28. The secondary end points were changes in the patient global assessment (PGA) score and itch visual analogue scale (VAS) score of the trunk between baseline and day 28. RESULTS: Two hundred and ninety-one patients were recruited, and 176 patients completed the full 4-week treatment course. By the end of the treatment, the mean local EASI of the trunk (2.2±4.71) was significantly decreased from that at baseline (4.71±4.03, p < 0.001). PGA (1.71±1.15) and itch VAS score of the trunk (2.61±2.19) on day 28 were also profoundly decreased compared with the baseline (2.96±1.07 and 5.15±2.47, respectively). No serious adverse events were observed during the study period. CONCLUSION: Topical tacrolimus is an effective and safe therapy for truncal lesions in AD patients.
