Prevalence of allergic contact dermatitis in children with and without atopic dermatitis: A multicenter retrospective case-control study.

BACKGROUND: As both allergic contact dermatitis and atopic dermatitis (AD) have similar clinical presentations and are characterized by spongiotic dermatitis on skin biopsy, many children with AD are not referred for patch testing and allergic contact dermatitis is underdiagnosed. OBJECTIVE: To provide updated prevalence data of common contact allergens in children with and without AD. METHODS: This is a retrospective case-control study using the Pediatric Allergic Contact Dermatitis Registry from 2018 to 2022. RESULTS: A total of 912 children were included (615 with AD and 297 without AD). Children with AD were more likely to have a longer history of dermatitis (4.1 vs 1.6 years, P < .0001), have seen more providers (2.3 vs 2.1, P = .003), have greater than 1 positive patch test (PPT) result (P = .005), have a greater number of PPT results overall (2.3 vs 1.9, P = .012), and have a more generalized distribution of dermatitis (P = .001). PPT to bacitracin (P = .030), carba mix (P = .025), and cocamidopropyl betaine (P = .0007) were significantly increased in children with AD compared to those without AD. LIMITATIONS: Technical variation between providers and potential for misclassification, selection, and recall biases. CONCLUSION: Children with AD are significantly more likely to have PPT reactions and should be referred for evaluation of allergic contact dermatitis and obtain patch testing.

Adverse psychocutaneous effects of prescription stimulant use and abuse: A systematic review.

Although rare, psychocutaneous disorders induced by prescription stimulants have been reported throughout the literature. A systematic review was conducted to identify all case reports and case series of prescription stimulant-induced trichotillomania, tactile hallucinations, and delusional infestation. A total of 22 case reports were identified and relevant information was analyzed. Patients presenting with trichotillomania and tactile hallucinations induced by prescription stimulants were typically pediatric male patients being treated for attention deficit hypersensitivity disorder. Symptoms resolved after discontinuation of the offending medication. Patients presenting with delusional infestation secondary to stimulant use or abuse were typically adults who were misusing or abusing stimulant medication. Although symptoms typically improved or resolved after decreasing or discontinuing medication, several patients required the use of antipsychotic medication. While the observational nature of case reports and small number of patients limits meaningful analysis of trends and comparison, this study demonstrates that physicians, especially dermatologists and psychiatrists, should be aware of the potential for prescription stimulants to precipitate adverse psychocutaneous disorders in a minority of individuals.

Adjuvant treatment of chronic plaque psoriasis in adults by a herbal combination: Open German trial and review of the literature.

Psoriasis is a chronic inflammatory skin disease affecting up to 6% of the World population. Skin care is the basic approach to restore epidermal barrier function, provide symptomatic relief, and ensure remission-free periods. We performed an open trial using herbal complex Soratinex® (also known as Dr Michaels®) in adult patients with mild-to-moderate chronic plaque psoriasis without further improvement to previous treatments in the last 6 weeks. The products Cleansing Gel, Scalp & Body Ointment, and Skin Conditioner were applied twice daily for 8 weeks. All patients achieved a Psoriasis Area and Severity Index (PASI) 50 response, 94.4% achieved a PASI 75, 66.7% achieved PASI 90, and 22.2% achieved a PASI 100. In week 8, 94.4% of patients were satisfied or very satisfied with the treatment that was well tolerated. We performed a literature review on published trials in children and adults suffering from psoriasis. Herbal complex Soratinex® achieved a PASI 50 or more in about 50-90% of patients. It ensures prolonged relapse-free periods and improves the quality of life. Adverse events are mild and seen in a minority of patients only. In conclusion, herbal complex allows safe and effective self-treatment of patients with psoriasis and improves patient's autonomy.

Functional nutrition as integrated approach in vitiligo management.

Vitiligo is a common disease of unknown cause that produces disfiguring white patches of depigmentation that can be treated using various new and experimental therapies, such as narrow-band ultraviolet B (NB-UVB) microphototherapy, NB-UVB excimer laser, and monochromatic excimer light. Medical treatments include topical corticosteroids and other topical treatments, such as antioxidants, tacrolimus and pimecrolimus, prostaglandin E, and vitamin D derivatives (Lotti, Berti, & Moretti, 2009). The goal of treating vitiligo is to make it less noticeable either by restoring lost pigment or by eliminating remaining pigment. Functional foods and healthy diet, with nutrients, form a variety of sources, could be considered an integral part, as well as helpful, of vitiligo's medical therapy.

Platelet rich plasma in androgenetic alopecia: A systematic review.

In recent years, dozens of manufacturers and clinics have been promoting the use of platelet rich plasma (PRP) procedures for skin and hair regeneration. Well-designed randomized controlled studies for these procedures are lacking. In this communication, we review the efficacy and safety of PRP procedures for androgenetic alopecia from multiple published peer-reviewed studies. The conclusion of our analysis is that until the present moment there is not enough evidence for the use of PRP procedures in the treatment of androgenetic alopecia. We hope that this review will help practitioners and patients to make better-informed treatment decisions.

Trichotillomania (hair pulling disorder): Clinical characteristics, psychosocial aspects, treatment approaches, and ethical considerations.

Trichotillomania (hair pulling disorder) is a fairly common but underreported disorder characterized by recurrent episodes of pulling hair from different parts of the body. Currently classified in Diagnostic and Statistical Manual of Psychiatric Disorders (DSM-5) under the heading of the "Obsessive-compulsive spectrum and related disorders." The estimated prevalence data suggest that 0.5-2% of the general population suffers from this disorder. Stress and anxiety are directly correlated to the production of trichotillomania symptoms. The psychosocial aspects of trichotillomania are greatly underestimated, but recent literature suggests an increased interest in this neglected area. Although no FDA approved medications are available for the treatment of trichotillomania, a variety of medications including N-acetylcysteine have shown benefit in case reports. Combined liaison clinics, with an interdisciplinary approach, are highly advisable in the treatment of these cases.

Complementary and integrative therapies for psoriasis: Looking forward.

Despite the great advances in our understanding of disease pathogenesis and a rich variety of therapeutic options, including the availability of newer biologic agents, there is still no cure for psoriasis. Based on low levels of satisfaction in the treatment they receive and their overall care, it is not surprising that a substantial part of patients turn to complementary and alternative therapies. Integrative medicine is an exciting new approach to health care. The dermatologist should recognize this growing trend and become familiar with the current literature on integrative therapies for psoriasis. Several complementary therapies, those that have been found to be safe and effective, can be recommended as part of an integrative treatment plan.

Patient-reported outcomes: A 5-year long study reveals previously unreported therapeutic, demographic, socio-economic, and other correlations in vitiligo.

Vitiligo is a non-lethal, non-communicable, immune-mediated, and generally progressive skin disease, with poorly understood etiopathogenesis and weak evidence base. The aim of the study is to contribute to the scant research on the patient-reported outcomes in vitiligo, and to examine the presence of associations between various inputs for possible use in clinical practice. The study was designed as a web-based questionnaire with 40 inputs across seven dimensions. The questions include demographics, skin type, eye and natural hair color, age of respondent and age of onset, possible triggers, disease extent, localization, progression and activity, the efficacy of most common treatment modalities, medication side-effects, heredity and diseases among parents, and out-of-pocket expenses for treatments to date. The analysis presented with this work contributes to the discussion about the relation between therapies, socio-economic factors, and treatment outcomes in vitiligo. All physicians should adequately manage patient expectations in terms of overall treatment duration and expected out-of-pocket expenses, and actively evaluate patients at shorter intervals. A more aggressive therapeutic approach using telehealth devices should be considered to supplement therapy, monitor treatment progress, and protocol compliance.

Primavera: A new therapeutical approach to vulvo-vaginal atrophy.

Vulvovaginal atrophy is a condition that affects women, although it is mainly associated with the onset of menopause mainly due to hormonal changes vulvovaginal laxity and mucosal atrophy can also affect women at different life stages such as after pregnancy or for cancer patients who have undergone chemo or endocrine therapy. This condition negatively influence quality of life, sexual desire, and self-confidence. Many therapies have been considered mainly with inconclusive or transient results in terms of benefit factor. Recently, a new non-invasive product, containing hyaluronic acid, oligopeptides, and antioxidants was introduced to the market. Its name is "Primavera," by Renaissance, Italy. The aim of this product is to allow a vulvo-vaginal biostimulation and considered simple, safe, and satisfactory.

Psychosocial aspects associated with use of sunscreen, natural sunlight exposure, and artificial tanning.

Natural and artificial tanning have become very popular in Western culture, yet at the same time, there is still a psychodermatology concern for this activity. Not much has been examined with the psychological aspects of tanning and sunscreen use. The purpose of this study is to examine the psychosocial effects associated with sun protection, natural, and artificial tanning among individuals 18 years old or older visiting the University of Miami Dermatology Outpatient Clinic. We distributed a survey on tanning and sunscreen use to 150 dermatology outpatients, hospital employees, and hospital visitors for three weeks during June/July 2015 asking about how often they tan, use sunscreen, and how they feel about this topic. Demographics, such as gender, ethnicity, and education were taken into consideration to examine the different responses in each category. Our results suggest that people's perception to tanning and sunscreen use have evolved over time. Most people in South Florida nowadays feel guilty when exposed to natural sunlight without sunscreen and do not tan frequently. The majority of the people, specifically women, utilize the recommended amount of sunscreen with a sun protection factor of 30-50. However, we can conclude that communication between social media and the general public can affect people's decision-making on tanning and sunscreen use with physician advice being the most effective method of encouraging people to use sunscreen. This study will add to the growing knowledge about psychodermatology.

Histopathologic pitfalls of Mohs micrographic surgery and a review of tumor histology.

Mohs micrographic surgery is a specialized subset of staged surgical excisions with each subsequent stage being driven largely by the histologic findings of the previous stage. Therefore, it is imperative that histologic analysis is performed in an accurate manner. Frozen section and tissue flattening is a crucial step in Mohs surgery. Frozen sections introduce certain artifacts and these artifacts must be interpreted in the correct context. Basal and squamous cell carcinomas are the most common tumors encountered in Mohs micrographic surgery, and their histopathology is also associated with certain "pitfalls". Basal cell carcinoma should be distinguished from hair follicles, folliculocentric basaloid proliferations, poromas, nevus sebaceous, desmoplastic trichoepitheliomas, and spiradenomas, to name but a few histologic entities. Similarly, squamous cell carcinoma should be distinguished from hypertrophic actinic keratoses, pseudoepitheliomatous hyperplasia, sebaceous carcinoma, and microcystic adnexal carcinoma. In addition, there are numerous subtypes of basal cell and squamous carcinomas that the Mohs surgeon should be aware of due to differences in the biologic behavior of these tumors. This review presents a number of the common histologic pitfalls of Mohs micrographic surgery and a review of tumor histology.

Psycho-Neuro-Endocrine-Immunology: A Psychobiological Concept.

Psycho-Neuro-Endocrine-Immunology (P.N.E.I.) is a scientific field of study that investigates the link between bidirectional communications among the nervous system, the endocrine system, and the immune system and the correlations of this cross-talk with physical health. The P.N.E.I. innovative medical approach represents a paradigm shift from a strictly biomedical view of health and disease taken as hermetically sealed compartments to a more interdisciplinary one. The key element of P.N.E.I. approach is represented by the concept of bidirectional cross-talk between the psychoneuroendocrine and immune systems. The Low Dose Medicine is one of the most promising approaches able to allow the researchers to design innovative therapeutic strategies for the treatment of skin diseases based on the rebalance of the immune response.

The history of women in dermatology.

In the past and present, the status of men is often superior to women in most developing countries and it has a negative effect on the social development of these countries. If women are educated as men in a society, then this society can advance rapidly since the effect of educated women influence the quality of life and health in a positive way and not only for those women, but younger generations who follow them as well. This article reviews the history of some remarkable women in dermatology.

Werther's collection of medical moulages.

Moulages are individualized wax models that were very popular as teaching aids in medicine during the 19th and until the first half of the 20th century. After a period of decline, moulages have become a subject of interest again in more recent times since they represent unique artifacts of art, craftsmanship, and medical history. Werther's collection at Dresden-Friedrichstadt Hospital was one of the most important in Dresden-the capital of Saxony-during the period before World War II. Some relicts have survived and have been restored.

The history of Botulinum toxin: from poison to beauty.

Botulinum toxin, also called the "miracle toxin," is a neurotoxin produced by the bacteria Clostridium botulinum. It is known to block nerve signals that contract muscles resulting in a temporary paralysis of the muscles. Toxins type A and B have been extensively studied and utilized in the realm of beauty and cosmetology. Initially, the toxin gained popularity as a disease-causing "poison". It was only later that it found its way to becoming a must have in modern aesthetic practice. Today, this wonder toxin has proven to be an apt and convenient option in the field of anti-aging medicine.
