Abstract
Atopic dermatitis (AD) is associated with various quality of life concerns including poor sleep. Sleep impairments in children with AD are associated with increased risk of short stature, metabolic syndrome, mental illness and neurocognitive dysfunction. Although the association between AD and sleep disturbance is well established, the specific types of sleep disturbance in pediatric AD patients and their underlying mechanisms are not fully understood. A scoping literature review was performed to characterize and summarize the types of sleep disturbance in children (less than 18 years of age) with AD. 31 papers met inclusion criteria and extracted data were analyzed in an iterative manner. Two types of sleep disturbances were found to be more prevalent in pediatric AD patients in comparison to controls. One category was related to loss of sleep (increased frequency or duration of awakenings, increased sleep fragmentation, delayed sleep onset, decreased total sleep duration, and decreased sleep efficiency). Another category was associated with unusual behaviors during sleep (restlessness/limb movement/scratching, sleep-disordered breathing including obstructive sleep apnea and snoring, nightmares, nocturnal enuresis and nocturnal hyperhidrosis). Some mechanisms underlying these sleep disturbances include pruritus and induced scratching and increased proinflammatory markers induced by sleep loss. Sleep disturbance appears to be associated with AD. We recommend clinicians to consider interventions that may reduce sleep disturbances in children with AD. Further investigation of these sleep disturbances is needed to elucidate pathophysiology, develop additional treatments, and reduce negative impacts on the health outcomes and quality of life in pediatric AD patients.

Abstract
This study aimed to extract polysaccharides from Citrus medica L. var. sarcodactylis (finger citron fruits) and analyze their structures and potential bioactivities. A new polysaccharide named K-CMLP was isolated and purified by Diethylaminoethylcellulose (DEAE)-Sepharose Fast Flow and DEAE-52 cellulose column chromatography with an average molecular weight of 3.76 × 103 kDa. Monosaccharide composition analysis revealed that K-CLMP consisted of rhamnose, galactose, and glucose, with a molar ratio of 6.75:5.87:1.00. Co-resolved by methylation and two-dimensional nuclear magnetic resonance (NMR), K-CLMP was alternately connected with 1, 2-Rha and 1, 4-Gal to form the backbone, and a small number of glucose residues was connected to O-4 of rhamnose. The results of DPPH⋅ and ABTS+⋅ radical scavenging assays indicated that both crude polysaccharide Citrus medica L. var. polysaccharide (CMLP) and K-CLMP exhibited strong free-radical-scavenging properties in a dose-dependent manner. In addition, K-CMLP significantly inhibited the production of pro-inflammatory cytokines (IL-6 and TNF-α) and reactive oxygen species (ROS) in RAW 264.7 cells treated with LPS. These results provide a basis for further use as one of the potential functions of food or natural medicine.

Abstract
Obstructive Sleep Apnea (OSA) damages the health of 35% of adult Americans. Disordered sleep results in increased risk of several autoimmune disorders, but the molecular links to autoimmunity are poorly understood. Herein, we identified four cytokines associated with autoimmune disease, whose median serum levels were significantly different for OSA patients receiving airways therapy, from the levels in untreated OSA patients, APRIL (5.2-fold lower, p = 3.5 × 10-11), CD30 (1.6-fold higher, p = 7.7 × 10-5), IFN-Alpha-2 (2.9-fold higher, p = 9.6 × 10-14) and IL-2 (1.9-fold higher, p = 0.0003). Cytokine levels in airways treated patients were similar to the levels in control subjects. t-SNE and UMAP analysis of these high dimensional patient cytokine data identified only two groups, suggesting a similar global response for all four cytokines to airways therapy. Our findings suggest the levels of these four cytokines may be altered by disordered sleep and perhaps by chronic hypoxia. Therapeutic options are discussed.

Abstract
Purpose of the Review Skin disease is associated with obstructive sleep apnea (OSA) both epidemiologically and mechanistically. In this review we highlight conditions which have a well-established link to obstructive sleep apnea, such as psoriasis and atopic dermatitis. Recent findings We describe putative mechanistic links between OSA and skin disease involving inflammatory pathways, obesity, mechanical upper airways obstruction, and hypoxia. In the context of these mechanisms we describe specific skin conditions, and other conditions which are associated with both skin manifestations (including hair/nail findings) and OSA. The risks/ benefits of CPAP in the context of skin disease are also reviewed. Summary We conclude that further research is needed to understand the mechanisms behind the associations between OSA and skin disease. Given the frequent co-occurrence of OSA and skin conditions, there would be great benefit for OSA clinical trials to consider improvement in skin disease as an outcome measure.

Abstract
Atopic dermatitis is associated with an increased risk of asthma (10 to 30% according to age), allergic rhinitis and conjunctivitis and food allergy. Other comorbidiies are globally lest frequent than in psoriasis. There is no increased risk of solid cancer. Smoking is a major confounding factor that has to be taken into account. Obesity and metabolic syndrome are more frequent and there is a moderately increased cardiovascular risk in severe forms of atopic dermatitis. There is a clear-cut increased risk of vitiligo and alopecia areata and a lower risk of other auto-immune diseases, including type I diabetes in children. There is a higher risk of cutaneous but not extra-cutaneous bacterial and viral infections, and increased frequency of contact dermatitis and urticaria. Severe atopic dermatitis is associated with psychiatric comorbidities, like attention disorders/hyperactivity, depression and suicidal ideas. © 2019 Elsevier Masson SAS. All rights reserved.

Abstract
Rosacea is a chronic facial skin disease involved in neurovascular dysregulation and neurogenic inflammation. Behavioral factors such as stress, anxiety, depression and sleep were identified to be associated with other inflammatory skin diseases. Few studies have reported sleep status in rosacea. Aiming to investigate the relationship between rosacea and sleep, a case-control survey was conducted, enrolling 608 rosacea patients and 608 sex- and age-matched healthy controls. Sleep quality was assessed through the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Diagnosis and severity grading of rosacea were evaluated under the standard guidelines of the National Rosacea Society. More rosacea patients (52.3%, n = 318) suffered poor sleep quality (PSQI, >5) than the healthy controls (24.0%, n = 146), displaying a much higher PSQI score (rosacea vs control, 6.20 vs 3.95). There was a strong association between sleep quality and rosacea (odds ratio [OR], 3.525; 95% confidence interval [CI], 2.759-4.519). Moreover, the severity of rosacea was also associated with sleep quality (OR, 1.847; 95% CI, 1.332-2.570). Single nucleotide polymorphisms in hydroxytryptamine receptor 2A and adrenoceptor-β1 genes, which are associated with sleep behaviour, were detected and revealed to be associated with rosacea. Furthermore, the LL-37-induced rosacea-like phenotype and sleep-deprivation mice models were applied, revealing that sleep deprivation aggravated the rosacea-like phenotype in mice, with higher expression of matrix metallopeptidase 9, Toll-like receptor 2, cathelicidin antimicrobial peptide and vascular endothelial growth factor. In conclusion, rosacea patients presented poorer sleep quality, as well as a higher propability of genetic background with sleep disturbance. In addition, poor sleep might aggravate rosacea through regulating inflammatory factors, contributing to a vicious cycle in the progression of disease.

Abstract
Asthma is a complex condition that affects 14% of the world's children and the approach to management includes both pharmacologic as well as non-pharmacologic strategies including attention to complex socioeconomic status phenomena. After an historical consideration of asthma, allergic and immunologic aspects of asthma in children and adolescents are presented. Concepts of socioeconomic aspects of asthma are considered along with environmental features and complications of asthma disparities. Also reviewed are links of asthma with mental health disorders, sleep disturbances and other comorbidities. A stepwise approach to asthma management is discussed that includes pharmacologic and non-pharmacologic strategies in the pediatric population. The role of immunotherapy and use of various immunomodulators are considered as well.

Abstract
STUDY OBJECTIVES This study has investigated the risk of major adverse cardiovascular events (MACEs), including acute myocardial infarction, coronary artery disease, peripheral artery disease, and acute stroke, among children and adolescents (age younger than 20 years) with obstructive sleep apnea (OSA). METHODS In this study, the population-based National Health Insurance Research Database of Taiwan was used to identify patients in whom OSA had been first diagnosed between 2000 and 2015. Children and adolescents with OSA (n = 6,535) were included with 1:3 ratio by age, sex, and index year of control participants without OSA (n = 19,605). The Cox proportional regression model was used to evaluate the risk of MACEs in this cohort study. RESULTS After a 15-year follow-up, the incidence rate of MACEs was higher in the OSA cohort when compared with the non-OSA control cohort (15.97 and 8.20 per 100,000 person-years, respectively). After adjusting for covariates, the risk of MACEs among children and adolescents with OSA was still significantly higher (hazard ratio = 2.050; 95% confidence interval = 1.312-3.107; P = .010). No MACEs were found in the children and adolescents with OSA who received continuous airway positive pressure treatment or pharyngeal surgery. CONCLUSIONS This study found a significantly higher risk of MACEs in children and adolescents with OSA. These findings strongly suggest that clinicians should provide careful follow-up and medical treatment for children and adolescents with OSA.

Abstract
Sleep disturbance is very common in patients with atopic dermatitis (AD) and is a major factor leading to impaired quality of life. Sleep disturbance is often viewed as one of the symptoms of AD and one of the measures of disease severity. In this review we describe a variety of sleep disorders associated with AD and a wide range of effect that sleep disorders have on patients with AD. We also discuss our current understanding of the mechanism of sleep disturbance in patients with AD. The relationship between sleep disorders and AD might be bidirectional and could form a vicious cycle. Therefore we suggest viewing sleep disorders as a comorbidity of AD for which regular screening and bidirectional management strategies are indicated, with equal focus on maintaining disease control and implementing specific strategies to improve sleep.

Abstract
BACKGROUND Routinely collected electronic health data obtained for administrative and clinical purposes are increasingly used to study atopic dermatitis (AD). Methods for identifying AD patients in routinely collected electronic health data differ, and it is unknown how this might affect study results. OBJECTIVES To evaluate how patients with AD have been identified in studies using routinely collected electronic health data, to determine whether these methods were validated and to estimate how the method for identifying patients with AD affected variability in prevalence estimates. METHODS We systematically searched PubMed, Embase and Web of Science for studies using routinely collected electronic health data that reported on AD as a primary outcome. Studies of localized AD and other types of dermatitis were excluded. The protocol for this review was registered in PROSPERO (CRD42016037968). RESULTS In total, 59 studies met eligibility criteria. Medical diagnosis codes for inclusion and exclusion, number of occasions of a code, type of provider associated with a code and prescription data were used to identify patients with AD. Only two studies described validation of their methods and no study reported on disease severity. Prevalence estimates ranged from 0·18% to 38·33% (median 4·91%) and up to threefold variation in prevalence was introduced by differences in the method for identifying patients with AD. CONCLUSIONS This systematic review highlights the need for clear reporting of methods for identifying patients with AD in routinely collected electronic health data to allow for meaningful interpretation and comparison of results.

Abstract
Pemphigus is an autoimmune bullous disease that causes the development of blisters and erosions on the skin and/or mucosa. Its inflammatory process is mediated by cytokines, which interact with sleep in a bidirectional manner. Pain, a frequent symptom due to pemphigus lesions, is well known to impair sleep quality. Depression is also associated with pemphigus and pro-inflammatory cytokines and may impair sleep. Additionally, a common relationship among other dermatological diseases and sleep has increasingly been described. Poor sleep quality is associated with an increased risk for autoimmune diseases, and insomnia is a comorbidity that has recently been associated with pemphigus. Thus, this review will explore the evidence supporting the likely bidirectional relationship between pemphigus and sleep quality and its possible mechanisms involved. This approach covering both pemphigus and sleep will open a research avenue for future studies focusing on the efficacy of the sleep disorders treatment in patients with pemphigus. In the long term, this may provide relevant information to dermatologists regarding new strategies for the management of pemphigus clinical condition, allowing possibly a better quality of life for the patients.

Abstract
Obstructive sleep apnea (OSA) is present in at least 2% of women and 4% of men, and its prevalence is increasing, because a major predisposing factor for OSA is a high body mass index. Psoriasis has the most strongly substantiated link with OSA, where the relationship may be bidirectional. Dermatologic disorders may be comorbid with OSA due to several factors: (i) the heightened proinflammatory state in OSA, which can occur independent of body mass index, and may exacerbate inflammatory dermatoses; (ii) intermittent hypoxemia may promote neovascularization and tumor growth in certain cancers, such as melanoma; (iii) obesity, present in majority of OSA patients, can be associated with a heightened proinflammatory state; (iv) upper airway obstruction due to local tumors or soft tissue swelling due to physical urticaria or angioedema; (v) acute nasal congestion in the atopic patient with allergic rhinitis; (vi) dermatologic disorders associated with other OSA risk factors (eg, acanthosis nigricans and metabolic syndrome); and (vii) a high sympathetic tone (eg, in atopic dermatitis) and resultant sleep fragmentation contributing to upper airway instability during sleep. In many instances, the dermatology patient with OSA may have other medical and psychiatric comorbidities that are also associated with increased OSA risk.

Simple obstructive sleep apnea patients without hypertension or diabetes accelerate kidney dysfunction: a population follow-up cohort study from Taiwan. Sleep Breath 2016; 21:85-91. [PMID: 27380033 PMCID: PMC5343077 DOI: 10.1007/s11325-016-1376-2] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2015] [Revised: 05/29/2016] [Accepted: 06/28/2016] [Indexed: 11/26/2022]
Abstract
Backgrounds Obstructive sleep apnea (OSA) is common in patients on hemodialysis, but its correlation with chronic kidney disease (CKD) is not clear. We aimed to clarify the relationship between OSA without hypertension or diabetes and incidence of CKD in Taiwan. Methods This population-based cohort study consisted of patients with newly diagnosed OSA between 2000 and 2009. The comparison cohort was matched for age, sex, diabetes mellitus, and hypertension. All subjects previously diagnosed with acute or chronic kidney disease were excluded. The primary end point was newly diagnosed CKD. Results We identified 6866 subjects with OSA during the 10-year study period. The median duration until development of CKD in the OSA cohort was 3.2 years, 2.5 months earlier than that in the non-OSA cohort. After exclusion of hypertension and diabetes, 4319 OSA patients was identified and the hazard ratio (HR) of CKD with OSA was 1.37 (95 % confidence interval [CI], 1.05–1.77; p = 0.019). In the subgroup analysis, an increased incidence of CKD in OSA was observed in women (HR, 1.41; 95 % CI, 1.12–1.78; p = 0.0036). Conclusions This longitudinal population-based cohort study provides evidence that patients with OSA even without diabetes or hypertension are at higher risk of developing CKD over the next 3 years and nearly 2.5 months earlier than the non-OSA cohort, particularly women.

Abstract
Our aim was to study the changes in bone age and serum osteocalcin levels before and after adenotonsillectomy (AT) in children with obstructive sleep apnea hypopnea syndrome (OSAHS). A total of 58 OSAHS children (37 males and 21 females) with the mean age of 6.68 ± 1.11 years were enrolled and assessed by x-ray-based bone age estimation and enzyme-linked immunosorbent assay-based measurement of serum osteocalcin levels, before surgery and 6 months after AT. SPSS 19.0 software was used for statistical analysis. Our results revealed that bone age and serum osteocalcin levels in OSAHS patients were significantly lower than normal controls before AT (P < 0.05). Within 6 months after surgery, the bone age and the serum osteocalcin levels were significantly elevated in OSAHS patients (P < 0.05), compared with those before surgery. Serum osteocalcin levels and bone age are negatively correlated with apnea-hypopnea index, oxygen desaturation index, the percentage of the total recorded time spent below 90% oxygen saturation, and Epworth sleepiness scale scores (all P < 0.05). Our findings suggested that bone age and serum osteocalcin levels may be correlated with the development of OSAHS in children. AT may improve bone age and serum osteocalcin levels in OSAHS children.

Abstract
Background Obstructive sleep apnoea (OSA) is frequently observed in severe asthma but the causal link between the 2 diseases remains hypothetical. The role of OSA-related systemic and airway neutrophilic inflammation in asthma bronchial inflammation or remodelling has been rarely investigated. The aim of this study was to compare hallmarks of inflammation in induced sputum and features of airway remodelling in bronchial biopsies from adult patients with severe asthma with and without OSA. Materials and Methods An overnight polygraphy was performed in 55 patients referred for difficult-to-treat asthma, who complained of nocturnal respiratory symptoms, poor sleep quality or fatigue. We compared sputum analysis, reticular basement membrane (RBM) thickness, smooth muscle area, vascular density and inflammatory cell infiltration in bronchial biopsies. Results In total, 27/55 patients (49%) had OSA diagnosed by overnight polygraphy. Despite a moderate increase in apnoea-hypopnoea index (AHI; 14.2±1.6 event/h [5–35]), the proportion of sputum neutrophils was higher and that of macrophages lower in OSA than non-OSA patients, with higher levels of interleukin 8 and matrix metalloproteinase 9. The RBM was significantly thinner in OSA than non-OSA patients (5.8±0.4 vs. 7.8±0.4 μm, p<0.05). RBM thickness and OSA severity assessed by the AHI were negatively correlated (rho = -0.65, p<0.05). OSA and non-OSA patients did not differ in age, sex, BMI, lung function, asthma control findings or treatment. Conclusion Mild OSA in patients with severe asthma is associated with increased proportion of neutrophils in sputum and changes in airway remodelling.

Abstract
Obstructive sleep apnea (OSA), characterized by repetitive episodes of apnea/hypopnea and hypoxia, is associated with systemic inflammation and induces metabolic, endocrine, and cardiovascular diseases. Inflammation might have an impact on neurodegenerative diseases. This study investigates the possible association between OSA and Parkinson's disease (PD). Random samples out of 1 million individuals were collected from Taiwan's National Health Insurance database. A total of 16,730 patients with newly diagnosed OSA from 2002 to 2008 were recruited and compared with a cohort of 16,730 patients without OSA matched for age, gender, and comorbidities using propensity scoring. All patients were tracked until a diagnosis of PD, death, or the end of 2011.During the mean 5.6-year follow-up period, the incidence rates of PD were 2.30 per 1000 person-years in the OSA cohort and 1.71per 1000 person-years in the comparison group. The incidence rate ratio (IRR) for PD was greater in older patients (≧ 65 years) and male patients with OSA than the controls, respective IRRs being 1.34 and 1.47. After adjustment for the comorbidities, patients with OSA were 1.37 times more likely to have PD than patients without (95% CI = 1.12-1.68, P < 0.05). Subgroup analysis showed that older patients and patients with coronary artery disease, stroke, or chronic kidney disease had a higher risk for PD than their counter parts. Log-rank analysis revealed that patients with OSA had significantly higher cumulative incidence rates of PD than the comparison group (P = 0.0048). Patients with OSA are at an increased risk for subsequent PD, especially elderly male patients.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Chinese herbal medicine (CHM) is commonly used to treat skin diseases, but CHM prescription patterns are difficult to understand due to their complexity and inter-connections. This study aimed to demonstrate CHM core treatments and network for treatment of allergic skin diseases by analyzing a nationwide prescription database. MATERIALS AND METHODS All CHM prescriptions made for atopic dermatitis (with age limitation ≤ 12 years) and urticaria for the entire year of 2011 were included. Association rule mining (ARM) combined with social network analysis (SNA) were used to analyze CHM prescriptions and explore the CHM prescription pattern and network. RESULTS A total of 27,350 and 97,188 prescriptions for atopic dermatitis and urticaria, respectively, were analyzed. Xiao-Feng-San (XFS) was the most commonly used CHM (32% of prescriptions for atopic dermatitis and 47.4% for urticaria) and was the core treatment for both diseases. Moreover, 42 and 82 important CHM-CHM combinations were identified to establish the CHM network, and XFS with Dictamnus dasycarpus Turcz was the most prevalent (6.4% for atopic dermatitis and 9.1% for urticaria). Traditional Chinese Medicine heat syndrome was most prevalent cause. Extensive anti-inflammation, anti-allergy, anti-oxidation, and anti-bacterial effects were also found among the CHMs. CONCLUSIONS Network analysis on CHM prescriptions provides graphic and comprehensive illustrations regarding CHM treatment for atopic dermatitis and urticaria. The CHM network analysis of prescriptions is essential to realize the CHM treatments and to select suitable candidates for clinical use or further studies.

Abstract
AIM Viral respiratory infections and atopy have been implicated in the pathogenesis of adenotonsillar hypertrophy and obstructive sleep apnoea (OSA), but the role of atopy is controversial. We aimed to test our hypothesis that atopy, expressed as physician-diagnosed eczema, was associated with adenotonsillar hypertrophy and OSA among children who snored. METHODS Data on children who snored and were referred for polysomnography were reviewed. The primary outcome measures were adenotonsillar hypertrophy and OSA. RESULTS We analysed data on 855 children with a mean age (±standard deviation) of 6.3 (±2.5) years and median obstructive apnoea-hypopnea index of 2.1 episodes per hour. Of the 855 subjects, 133 (15.6%) had physician-diagnosed eczema, 591 (69.1%) had adenoidal hypertrophy, 605 (70.8%) had tonsillar hypertrophy, 219 (25.6%) were obese and 470 (55%) had OSA. Eczema was not related to adenoidal or tonsillar hypertrophy after adjustment for gender and age, with odds ratios (OR) of 1.00 (95% confidence interval 0.67-1.49; p = 0.98) and 0.88 (95% confidence interval 0.59-1.32; p = 0.54), respectively. Similarly, eczema did not affect OSA frequency after adjustment for adenoidal and tonsillar hypertrophy, obesity, gender and age, with an adjusted OR of 0.82 (0.56-1.21; p = 0.32). CONCLUSIONS Atopy was not related to adenotonsillar hypertrophy or OSA in children who snore.

Abstract
BACKGROUND Obstructive sleep apnea-hypopnea syndrome (OSAHS) is associated with premature atherosclerosis. However, the associated mechanism remains unknown. This study investigates the expression of adenosine triphosphate (ATP)-binding cassette transporter protein A1 (ABCA1) and cellular cholesterol efflux in cultured macrophages from OSAHS patients. METHODS Of the 18 subjects enrolled in this study, six subjects with apnea-hypopnea index (AHI) <5 were placed into the control group, and 12 subjects with AHI ≥5 were placed into the OSAHS group. Peripheral blood mononuclear cells (PBMCs) from each subject were isolated, purified, cultured, and differentiated into macrophages in vitro. ABCA1 mRNA and protein expression were evaluated by reverse transcription PCR and Western Blot, respectively. Both ABCA1-mediated and autologous serum induced cholesterol efflux were measured by isotopic cholesterol efflux assays. RESULTS The levels of AHI and high sensitivity C-reactive protein (hsCRP) were significantly higher in the OSAHS group than in the control group. ABCA1 mRNA and protein expressions in PBMCs-derived macrophages were significantly reduced in patients with OSAHS compared to that in controls (p < 0.05). Both ABCA1-mediated and autologous serum-induced cholesterol efflux were significantly lower in the OSAHS group than that in the control group (p = 0.033 and p = 0.01, respectively). Pearson's correlation analysis revealed a negative correlation between AHI and the mRNA (r = -0.7726, p = 0.0007) and protein (r = -0.8112, p = 0.0044) expression of ABCA1, a positive correlation between ABCA1-mediated cholesterol efflux and the minimum oxygen saturation (r = 0.7954, p < 0.0001), and a negative correlation between AHI and autologous serum induced cholesterol efflux (r = -0.7756, p = 0.0002). CONCLUSION ABCA1 expression and cellular cholesterol efflux in macrophages were significantly decreased in OSAHS patients, which closely correlated with the severity of disease. Our findings provide meaningful insights into the mechanism of atherogenesis in OSAHS patients.

Abstract
Several diagnoses in the new DSM-5 chapter on 'Obsessive-Compulsive and Related Disorders' directly relate to psychodermatology. The new excoriation (skin-picking) disorder (SPD) and trichotillomania (TTM) both manifest as recurrent body-focused repetitive behaviors that have compulsive and dissociative features, the latter being more prevalent in TTM than SPD. The DSM-5 refers to SPD and TTM occurring without full awareness or preceding tension, however does not specifically mention the possible role of dissociation. This has important treatment implications, as patients with high dissociative symptoms are not likely to respond to the standard treatments for obsessive-compulsive disorder. Body dysmorphic disorder (BDD), which is frequently associated with cutaneous body image (CBI) dissatisfaction, is present in 9%-15% of dermatology patients. Treatment guidelines in dermatology are increasingly considering the psychosocial morbidity related to CBI in their treatment outcome measures. The presence of BDD, if unrecognized, may therefore directly affect the dermatologic treatment regimens offered to the patient.
