RESUMEN

BACKGROUND: IPL devices emit a wide range of wavelengths that can be absorbed by different chromophores in the skin. Selective destruction of a specific chromophore with minimal side effects is controlled by wavelength, pulse duration, and fluence. AIM: This study aims to evaluate the treatment of vascular and pigmented lesions using narrow-band Intense Pulsed Light (IPL) with Advanced Fluorescence Technology (AFT), which offers more efficient energy usage per pulse to increase safety, and improve clinical outcomes. METHODS: A retrospective analysis of data from 100 patients treated with narrow-band IPL for vascular and pigmented lesions. Efficacy was measured by the Global Aesthetic Improvement Scale (GAIS) and Patient Satisfaction Scale (0-10). Safety was assessed by evaluating pain levels and adverse events. RESULTS: Mean GAIS scores were 8.02 ± 0.84 for vascular and 8.14 ± 0.9 for pigmented lesions with no significant difference between groups (p=0.49, α=0.05). Patient satisfaction correlated with GAIS scores (correlation coefficient 0.8). No pain was reported and two patients experienced temporary and transient side effects. CONCLUSION: Overall, the advanced IPL treatments provided favorable outcomes for vascular and pigmented lesions.

RESUMEN

BACKGROUND: Pigmented lesions are largely benign and may lead to extreme distress. Various light and lasers may be used to treat pigmentation, often Q-switched lasers are considered the method of choice, while intense pulsed light (IPL) devices may offer a less invasive treatment with a shorter downtime. OBJECTIVE: The purpose of this study is to evaluate the safety and efficacy of a narrowband IPL module for the treatment of pigmented lesions. METHODS: A retrospective study of 20 patients with pigmented lesions underwent treatment with an IPL module. Treatment was assessed by blinded evaluation of clinical photographs using a GAIS scale of 0-10, as well as through patient satisfaction ratings on a scale of 0-10. Throughout the treatment, pain levels and adverse events were monitored. RESULTS: The mean GAIS score was 7.55 ± 1.15 (mean ± SD), and the mean patient satisfaction score was 7.3 ± 1.26 (mean ± SD). There was a strong positive correlation between GAIS and patient satisfaction scores (r = 0.83), and no significant difference between them (p-value = 0.516). The number of treatments did not significantly affect GAIS and patient satisfaction scores (p-values 0.364 and 0.126). Additional positive unexpected outcomes were improved skin firmness and reduced wrinkles. CONCLUSION: The results of the study indicate that the IPL module is both safe and effective in treating pigmented lesions and may have the potential to stimulate collagen production.

RESUMEN

Stevens-Johnson syndrome and toxic epidermal necrolysis are potentially life-threatening cutaneous diseases that are rarely seen in the pediatric population. We describe a case of a 7-year-old female who presented with fever, cough, mucosal erosions, and a widespread maculopapular eruption with flaccid bullae for 4 days. She had no sick contacts and no new medications, supplements, or vitamins. She then rapidly developed ulcerations in her oral mucosa and genital area, numerous scattered tense bullae throughout her body, and patchy areas of desquamation. Infectious disease workup revealed positivity only for Bordetella parapertussis, and she was subsequently diagnosed with idiopathic toxic epidermal necrolysis.

RESUMEN

Background Chronic skin conditions are different from internal illnesses since they are often immediately visible to others. Patients feel self-conscious and often go through depression, anxiety, fear of stigma and a substantial psychological, social and economic impact. It is crucial for healthcare professionals to gather information about various strategies and psychosocial interventions that can be used to manage psychological distress associated with skin conditions and avoid it from being neglected amidst other health conditions. Mindful Self-Compassion (MSC) can be used for this. It is a resource-building mindfulness-based self-compassion training programme that uses a combination of personal development training and psychotherapy designed to enhance one's capacity for self-compassion by cultivating spacious awareness as a basis for compassionate action. Aims This study examined the impact of mindful self-compassion on depression, anxiety, stress, dermatology-specific quality of life, self-esteem and well-being in a sample of 88 adults aged 18-55 years suffering from chronic skin conditions. Methods This study used an experimental waitlist control design. Participants were recruited from two skin clinics using purposive sampling in Mumbai, Maharashtra. Pre-test data was collected through self-reported questionnaires on psychological distress, dermatology-specific quality of life, self-esteem and well-being. Participants who were experiencing psychological distress were randomly assigned to either the experimental or waitlist control group. The intervention named 'mindful self-compassion' was delivered through an online platform, twice a week, over a period of 4 weeks. Post-test data was collected later on all variables. Results ANCOVA was utilised where pre-test scores were used as covariates. Differences in pre-test and post-test scores between the intervention group and waitlist control group for depression, anxiety, stress, dermatology-specific quality of life, self-esteem and well-being were analysed. Participants in the intervention group were found to have lower levels of depression, anxiety and stress as compared to the waitlist control group and also had enhanced levels of self-esteem, well-being and dermatological quality of life. These differences were found to be statistically significant (p < 0.001). Limitations The sample reflected heterogenous skin conditions, not a specific skin condition. The study was quantitative in nature, and we could not use any qualitative methods to assess the subjective experience of participants. Due to time constraints, follow-up data could not be gathered from participants to assess long-term effects on participants. Conclusion Mindful self-compassion can be effectively used to manage psychological distress in skin conditions. Dermatologists can become acquainted with basic signs of mental distress and the importance of psychological interventions. By collaborating with mental health professionals, patients can be given holistic treatment.

RESUMEN

Chloasma, which is distinguished by irregularities in the pigmentation of skin, poses substantial challenge in the field of dermatology. The regulatory influence of vitamin D on the functions of skin cells implies that it may have the capacity to effectively treat chloasma and promote wound healing. To assess the efficacy of vitamin D in chloasma treatment and its impact on the function of skin barrier during the process of wound healing. The research spanned from April 2022 to September 2023, in Shanghai, China, examined 480 individuals who had been diagnosed with chloasma. A double-blind, placebo-controlled clinical trial was utilized to evaluate effectiveness of topical vitamin D3 in treatment of chloasma. Concurrently, randomized control trial investigated the effects of ingested vitamin D3 supplements on the process of wound healing. Transepidermal water loss (TEWL), chloasma severity score changes, wound size reduction and skin hydration levels were critical performance indicators. Statistically, the severity scores of chloasma decreased significantly in the vitamin D treatment group at 3 and 6 months compared with the placebo (p < 0.05). The Vitamin D group exhibited superior wound healing outcomes, including more substantial reduction in lesion size and enhanced skin barrier function, as evidenced by increased skin hydration and decreased TEWL (p < 0.05). Vitamin D substantially mitigated the severity of chloasma and has beneficial effect on wound healing and integrity of the skin barrier. Based on the results obtained, vitamin D exhibited promise as a therapeutic intervention in the field of dermatology, specifically in treatment of chloasma and promotion of wound recovery.

RESUMEN

Vitiligo skin has a lesser number of photoprotective melanocytes-theoretically, there is a higher risk of development of non-melanoma skin cancers in such patients. But most studies in Caucasian patients have shown decreased incidence of non-melanoma skin cancers in patients with vitiligo. In Indian patients, there is a paucity of literature on such adverse events. We report a case of actinic keratoses, cutaneous horn with dysplasia and squamous cell carcinoma developing exclusively over photo-exposed vitiligo lesions in an Indian woman in her 60s (housewife, Fitzpatrick skin type V and average daily photo-exposure time 2-4 hours) of long-standing vitiligo vulgaris without any history of phototherapy. The photoprotected lesional skin was completely normal with no clinically appreciable enlarged regional lymph nodes. Shave and elliptical excision of the suspicious lesions were done, and histopathology showed various degrees of malignant transformation in various lesions. The patient was started on topical imiquimod for the lesions of actinic keratoses and was referred for staging and wide excision of squamous cell carcinoma lesion. We report this case for its rarity and to emphasise the fact that there is a need for counselling for lifestyle modification in patients with vitiligo as the use of sunscreens is often not practised by Indian patients due to financial constraints and physical measures such as using full sleeves, high-collared dresses and scarves should be encouraged.

RESUMEN

This paper explores the impact of osteopathic medicine's principles and philosophy on dermatology conditions, focusing specifically on atopic dermatitis (AD), bullous pemphigoid (BP), and acne scars. The aim is to investigate how integrating osteopathic principles into dermatology can improve patient outcomes by addressing visible and internal health factors. The review was conducted through a literature search utilizing PubMed and Journal Storage. By focusing on the interconnectedness of mind, body, and spirit, osteopathic medicine could contribute to the effective treatment of AD. Stress management techniques have been found to significantly aid in the treatment of AD, as stress levels and social stress have a significant impact on the exacerbation of AD symptoms. Micro-needling is a promising treatment for atrophic acne scars, reducing scar severity scores by up to 68.3%. Combining micro-needling with trichloroacetic acid or non-ablative fractional laser technology further enhances treatment efficacy. The development of BP has been linked to alterations in the epidermis. Granzyme B has been identified as a contributing factor in dermal-epidermal junction separation and autoantibody formation, leading to BP. However, the specific link between osteopathic manipulation and Granzyme B levels in BP is not yet firmly established. Although osteopathic manipulation may impact the immune system and inflammation, further investigation is required to determine its precise effects on granzyme B and BP. Nonetheless, integrating osteopathic principles and philosophy into dermatology can improve patient outcomes by addressing visible and internal health factors. The benefits of such integration include improved patient-provider relationships, innovative treatments, better stress management, and individualized care plans. Practitioners should be educated on the significance of complete skin examinations for all patients, and future research should focus on exploring the benefits of osteopathic manipulation for dermatologic conditions. Further investigations into new dermatological treatment methods rooted in osteopathic principles are encouraged. The foundation of dermatology and osteopathic medicine share the importance of physical touch for diagnosis and treatment. An osteopathic approach to dermatology considers the link between cutaneous diseases and systemic health. This approach aligns with the four fundamental osteopathic beliefs: the body functions as a whole unit; a person is an integration of body, mind, and spirit that cannot be separated. The body can regulate itself, heal itself, and maintain its health. The body's structure and function are interdependent and work together. Rational treatment is based upon an understanding of the basic principles of body unity, self-regulation, and the interrelationship of structure and function.

RESUMEN

BACKGROUND: Innovative technology can enhance patient access to healthcare but must be successfully implemented to be effective. OBJECTIVE: We evaluated Department of Veterans Affairs' (VA's) implementation of My VA Images, a direct-to-patient asynchronous teledermatology mobile application enabling established dermatology patients to receive follow-up care remotely instead of in-person. DESIGN /PARTICIPANTS/APPROACH: Following pilot testing at 3 facilities, the app was introduced to 28 facilities (4 groups of 7) every 3 months using a stepped-wedge cluster-randomized design. Using the Organizational Theory of Implementation Effectiveness, we examined the app's implementation using qualitative and quantitative data consisting of encounter data from VA's corporate data warehouse; app usage from VA's Mobile Health database; bi-monthly reports from facility representatives; phone interviews with clinicians; and documented communications between the operational partner and facility staff. KEY RESULTS: Implementation policies and practices included VA's vision to expand home telehealth and marketing/communication strategies. The COVID-19 pandemic dominated the implementation climate by stressing staffing, introducing competing demands, and influencing stakeholder attitudes to the app, including its fit to their values. These factors were associated with mixed implementation effectiveness, defined as high quality consistent use. Nineteen of 31 exposed facilities prepared to use the app; 10 facilities used it for actual patient care, 7 as originally intended. Residents, nurse practitioners, and physician assistants were more likely than attendings to use the app. Facilities exposed to the app pre-pandemic were more likely to use and sustain the new process. CONCLUSIONS: Considerable heterogeneity existed in implementing mobile teledermatology, despite VA's common mission, integrated healthcare system, and stakeholders' broad interest. Identifying opportunities to target favorable facilities and user groups (such as teaching facilities and physician extenders, respectively) while addressing internal implementation barriers including incomplete integration with the electronic health record as well as inadequate staffing may help optimize the initial impact of direct-to-patient telehealth. The COVID pandemic was a notable extrinsic barrier. CLINICAL TRIALS REGISTRATION: NCT03241589.

RESUMEN

Background: The factors necessitating the need for referrals for in-person evaluations by a dermatologist are not adequately understood and have not been studied using automated text mining so far. The objective of this study was to compare the prevalence of required in-person dermatologist care in the presence or absence of certain clinical features. Methods: Observational cross-sectional study of 11,661 teledermatology reports made from February 2017 to March 2020. Results: The need for dermoscopy was associated with a 348% increase in the possibility of referral for in-person dermatologist evaluations (prevalence ratio [PR]: 4.48, 95% confidence interval [CI]: 4.17-4.82). Infectious diseases were associated with a 64% lower possibility of referral (PR: 0.36, 95% CI: 0.30-0.43). Discussion: Some lesions and poorly documented cases are challenging to assess remotely. This study presents a different approach to research more detailed data from teledermatology reports, using text mining, and points out the risk magnitude for demanding dermatologic in-person care of which feature analyzed. As limitations, the variables related to lesion location, size, and extension were not analyzed and the dictionaries used were originally in Brazilian Portuguese. Conclusions: Teledermatology seems sufficient for the management of 75% of clinical cases, especially acute in young patients with inflammatory or infectious lesions. Referrals for in-person dermatologist consultations were not only strongly associated with the need for dermoscopy, but also for therapeutic reasons like surgical procedures, phototherapy, and the use of some systemic medications.

RESUMEN

Cellulitis is an acute bacterial infection that affects the deep dermis and surrounding subcutaneous tissue. Although it is a common condition, it is often misdiagnosed because it can mimic a range of conditions that also cause inflamed, red, irritated and painful skin. Such misdiagnoses may lead to unnecessary hospital admissions and antibiotic overuse, with most alternative diagnoses being non-infectious. Undertaking a holistic patient assessment, skin assessment and thorough clinical history is important in the diagnosis of cellulitis, and it is vital to use a collaborative multidisciplinary approach in its acute management and to prevent recurrence. This article defines the term cellulitis and explores its presenting features. The author also discusses the associated risk factors, clinical assessment techniques and effective management strategies, as well as outlining the actions that nurses can take to prevent recurrence.

RESUMEN

BACKGROUND: People with Neurofibromatosis Type 1 (NF1) suffer disfigurement and pain when hundreds to thousands of cutaneous neurofibromas (cNFs) appear and grow throughout life. Surgical removal of cNFs under anesthesia is the only standard therapy, leaving surgical scars. OBJECTIVE: Effective, minimally-invasive, safe, rapid, tolerable treatment(s) of small cNFs that may prevent tumor progression. METHODS: Safety, tolerability, and efficacy of 4 different treatments were compared in 309, 2-4 mm cNFs across 19 adults with Fitzpatrick skin types (FST) I-IV: radiofrequency (RF) needle coagulation, 755 nm alexandrite laser with suction, 980 nm diode laser, and intratumoral injection of 10 mg/mL deoxycholate. Regional pain, clinical responses, tumor height and volume (by 3D photography) were assessed before, 3 and 6 months post-treatment. Biopsies were obtained electively at 3 months. RESULTS: There was no scarring or adverse events > grade 2. Each modality significantly (P < .05) reduced or cleared cNFs, with large variation between tumors and participants. Alexandrite laser and deoxycholate were fast and least painful; 980 nm laser was most painful. Growth of cNFs was not stimulated by treatment(s) based on height and volume values at 3 and 6 months compared to baseline. LIMITATIONS: Intervention was a single treatment session; dosimetry has not been optimized. CONCLUSIONS: Small cNFs can be rapidly and safely treated without surgery.

RESUMEN

Therapeutic options are limited in cases of autosomal recessive congenital ichthyosis with inadequate response to topical agents. Acitretin is the current standard of care in these patients, but its use is limited by cumulative toxicity when prolonged therapy is needed in children. There is evidence to suggest that high doses of vitamin D can normalize keratinization and suppress inflammatory cytokines. Here, we report a patient with lamellar ichthyosis with a novel mutation in the Nipa-like Domain-Containing 4 (NIPAL4) gene. High dose short-term vitamin D therapy was administered with a dramatic and sustained clinical response.

RESUMEN

OBJECTIVE: This article reviews the efficacy and safety of 1% tapinarof cream for plaque psoriasis. DATA SOURCES: A literature search was conducted from August 2022 to February 2023. The terms tapinarof, VTAMA, benvitimod, GSK2894512, DMVT-505, and WBI-1001 were queried in PubMed. ClinicalTrials.gov was searched to identify ongoing or unpublished studies. STUDY SELECTION AND DATA EXTRACTION: All clinical trials written in English and relevant to pharmacology, efficacy, and safety were included. DATA SYNTHESIS: In two 12-week phase III clinical trials, disease severity assessed by a Physician's Global Assessment (PGA) score of clear or almost clear and a 2-point PGA improvement was 35.4% and 40.2% at week 12 in the 2 trials, respectively. In the 40-week, open-label extension trial, the efficacy and safety results were similar: 40.9% of patients achieved a PGA of 0 at least once during the trial, and 58.2% of patients with PGA ≥ 2 achieved PGA 0/1 at least once. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS: Tapinarof is a topical aryl hydrocarbon receptor agonist and a first-in-class, potentially promising treatment for plaque psoriasis recently approved by the U.S. Food and Drug Administration. CONCLUSION: Compared with placebo, tapinarof may be an effective and safe topical treatment for mild to severe plaque psoriasis. Head-to-head trials to compare the efficacy and adverse effect profile of tapinarof to other topical treatments are still needed, as are investigation in patients with recent or current use of phototherapy or biologic or nonbiologic systemics. Cost and adherence to treatment may be barriers for treatment efficacy.

RESUMEN

Skin of color refers to individuals whose skin color ranges from very light beige to very dark brown. Anthropologists and sociologists have previously recognized the importance of an objective classification of skin color for individuals with skin of color that does not include race and ethnicity. Since 1975, dermatologists have used the Fitzpatrick classification of sun-reactive skin types to categorize patients with skin of color; this classification was established for psoriasis patients participating in using oral methoxsalen and phototherapy clinical trial to determine the initial ultraviolet A dose. The Fitzpatrick classification merely classifies individuals as white, brown, and black; the individuals with white skin are further divided into four groups based on their burning or tanning capacity. This classification system does not provide reliable information with regard to the risk of skin cancer for individuals with darker skin color and does not aid in the evaluation of medical conditions with cutaneous involvement or assessment of appropriate cosmetic interventions for aesthetic management. Many clinicians, including forensic pathologists, incorporate the patient's race or ethnicity in their medical evaluation to describe the individual's skin color. Established scales for skin of color either include white skin color, or include 10 or more color types, or include both. We introduce a simple and rapidly performed scale that is not based on race or ethnicity to categorize persons with skin of color. The colorimetric scale ranges from very light beige to very dark brown and does not include white skin. The scale has five colors ranging from lightest (skin color type 1) to darkest (skin color type 5): very light beige (skin color type 1), light brown (skin color type 2), medium brown (skin color type 3), dark brown (skin color type 4), and very dark brown (skin color type 5); an individual with white skin would have a skin color type 0 in this classification of patient skin color. In conclusion, a scale that is not based on race or ethnicity is useful for categorizing individuals with skin of color not only for sociologists but also for clinicians who treat these patients. This colorimetric scale will be helpful for dermatologists to categorize persons with skin of color to predict their risk for developing skin cancer and to assessing appropriate cosmetic procedures and devices for these patients. In addition, the colorimetric scale will be useful for not only forensic pathologists but also other clinicians to provide a non-racial and non-ethnic designation of skin color type for their patients.

RESUMEN

Background: Melasma results from the imbalance of the mechanisms that regulate skin pigmentation, causing the appearance of hyperpigmented patches. Treatment includes topical and oral agents, chemical peelings, microneedling, and laser therapy. The picosecond laser was developed to minimize pain and skin discoloration, which can sometimes be associated with laser treatments. It emits short pulses of energy that last from 300 to 500 picoseconds, leading to a more significant fragmentation of melanin, with miniminal risk of scarring and thermal lesions in the surrounding skin. Objective: The authors aimed to review the use of picosecond laser in the treatment of melasma and further provide an overview of the other current available options. Conclusions: While the use of picosecond laser for the treatment of melasma has yielded good results, further studies with longer follow-up periods and a higher number of patients are needed.

RESUMEN

Scurvy, a disease caused by ascorbic acid (vitamin C) deficiency, is a rare disease in the modern world. We report a case of a boy in middle childhood, with a background of autism, presenting bed-bound due to progressive bilateral lower limb pain, with concomitant rashes, bleeding gums and worsening lethargy. Detailed dietary history revealed a severely restricted diet. Physical examination showed bilateral lower limb ecchymoses, perifollicular hemorrhages, perifollicular hyperkeratosis and cockscrew hairs which are pathognomonic features of scurvy. A low serum ascorbic acid level confirmed the diagnosis. Therapy with oral vitamin C supplement and rehabilitation with multidisciplinary care was successful, with complete resolution of symptoms. This case emphasises the importance of thorough dietary evaluation in children with autism and food selectivity presenting with non-specific symptoms. Physician awareness of nutritional deficiencies avoids unnecessary extensive investigations and sub-specialty referrals and translates to savings in medical expenses.

RESUMEN

Post-surgical scarring impacts quality of life (QOL) and is a significant source of morbidity. Existing treatments targeted at improving the appearance and morbidity of scarring include laser-based therapies. Although lasers are frequently used to improve scar appearance, the effects on QOL are unclear. A scoping review was conducted to assess the impact of laser-based therapy for patients with surgical facial scarring on QOL. Throughout literature review was conducted with the guidance of a medical librarian. Relevant articles underwent two rounds of screening by two, independent reviewers. Data were extracted from each article and later analyzed. Of the four articles analyzed, laser-based therapies were demonstrated as effective in improving QOL for patients with facial scars resultant from surgical intervention. Laser-based therapy should be considered when treating facial scarring resultant from surgical intervention, as it has been shown to improve patient QOL. Standardization of QOL assessment and further studies expanding scar inclusion should be pursued given the paucity of information found through this review.

RESUMEN

INTRODUCTION: Phototherapy and photodynamic therapy (PDT) are ultraviolet light (UV) based therapies for patients with skin diseases, and are sometimes associated with potential adverse events (AE)s, including erythema, pain, pruritus, burns, and photoaging. METHODS: We investigated UV phototherapy and PDT safety using the United States (US) Food and Drug Administration's (FDA)'s Manufacturer and User Facility Device Experience (MAUDE) database. The MAUDE database, including medical device reports (MDR)s informed by voluntary and obligatory reporters since 1991, was searched for AEs associated with UV phototherapy and PDT 1/1/91-3/1/23. RESULTS: There were 59 UV phototherapy and 33 PDT related MDRs. Burns were the most common AE type for both phototherapy and PDT. The majority of phototherapy AEs occurred during 2021 (52.3%), and were significantly more likely to occur at home than in the clinic. Overall, 76.1% of MDRs associated with home light boxes were prescribed by online retailers, most of the MDRs (59.3%) mentioned that it is prohibited to sell phototherapy devices not prescribed by physicians, and only 8.5% noted poorly written home light box instructions. DISCUSSION: The COVID-19 pandemic prohibited in-person light treatments, and social distancing requirements may have resulted in increased frequency of home-based light treatments. Hence, while at home treatment may be easier and more accessible, in-office physician supervised UV treatments are associated with less frequent AEs. Moreover, some phototherapy MDRs reported poorly written instructions accompanying the home light box, and some PDT MDRs documented patients receiving inadequate education regarding the procedure. With the rise of at-home treatment options and the ease of obtaining devices on the internet, it is physicians' duty to advise patients against self-treating with home light boxes without prescribed treatment regimens and educate patients that are considering home phototherapy to ensure safer patient experiences.
