Nanocarrier-Based Transdermal Drug Delivery Systems for Dermatological Therapy

Dermatoses are among the most prevalent non-fatal conditions worldwide. Given this context, it is imperative to introduce safe and effective dermatological treatments to address the diverse needs and concerns of individuals. Transdermal delivery technology offers a promising alternative compared to traditional administration methods such as oral or injection routes. Therefore, this review focuses on the recent achievements of nanocarrier-based transdermal delivery technology for dermatological therapy, which summarizes diverse delivery strategies to enhance skin penetration using various nanocarriers including vesicular nanocarriers, lipid-based nanocarriers, emulsion-based nanocarriers, and polymeric nanocarrier according to the pathogenesis of common dermatoses. The fundamentals of transdermal delivery including skin physiology structure and routes of penetration are introduced. Moreover, mechanisms to enhance skin penetration due to the utilization of nanocarriers such as skin hydration, system deformability, disruption of the stratum corneum, surface charge, and tunable particle size are outlined as well.

Drug therapy safety during pregnancy and breastfeeding

The treatment of dermatological diseases during pregnancy and breastfeeding poses particular challenges for the therapist for medical and legal reasons. Maternal and fetal influencing factors must be taken into account and the special need for protection of the fetus, infant, and mother must be considered in the treatment decision, usually outside of the approval process. Due to the lack of or insufficient evidence for most therapies during pregnancy and breastfeeding, an individual risk-benefit assessment should always be carried out, which also takes into account the risk of nontreatment. In the case of difficult or potentially momentous decisions, information from relevant databases, intercollegiate consultation and, if possible, advice from aclinical ethics committee should be obtained. In any case, the parents, and in particular the mother, should be carefully informed and their consent should be obtained and documented. Recommendations can be made for common chronic inflammatory and infectious dermatoses, but these should be reviewed on acase-by-case basis. For other therapy situations, an individual analysis and decision-making process is necessary. Overall, however, it can be stated that digital data processing and availability, combined with careful analysis, empathetic consideration and information for those affected, enables asuccessful treatment decision to be made in the vast majority of cases.

What's New After NICE Acne Guidelines.

Acne remains one of the most common inflammatory dermatoses seen worldwide. There are significant challenges when managing acne relating to a variety of factors, including (1) lack of consensus on the use of the numerous available grading systems and outcome measures, (2) appreciation of the numerous areas that relate to severity, (3) the chronic nature of acne which requires a longitudinal approach to management (including both facial and truncal disease), and (4) the need to target acne early to avoid physical and psychosocial scarring. Consideration of these aspects when managing acne should result in improved outcomes. Acne guidelines review the available evidence based on robust clinical trials and are usually supplemented with some expert opinion when evidence is not available. In this paper, the UK Acne Working Group reflects on the latest National Institute for Health and Care Excellence (NICE) acne guidelines with a goal of providing additional practical insights. The group have identified areas where new evidence has now become available since the formulation of the NICE acne guidelines. This publication considers newly approved acne medications in the UK, guidance on assessing acne severity, approaches to managing truncal acne, acne sequelae, and adult female acne with hormonal therapies.

Papulosquamous scalp dermatoses: key aspects of differential diagnosis and treatment

Psoriasis and seborrheic dermatitis are common papulosquamous dermatoses. When localized only on the scalp, they often have very similar clinical manifestations and require a comprehensive differential diagnostic approach. The article presents the main comparative clinical and diagnostic characteristics of psoriasis and seborrheic dermatitis of the scalp, including trichoscopy features and pathomorphological markers. Topical therapy with glucocorticosteroids, keratolytics and agents with antifungal activity is of key importance in the treatment of papulosquamous diseases. Modern topical drugs with a fixed combination of active ingredients provide an effect on several pathogenetic mechanisms at once, are stable, compatible, and convenient for use by patients. One of the main drugs for the treatment of psoriasis and seborrheic dermatitis is a solution of betamethasone dipropionate and salicylic acid (trade name – Akriderm SK), which in terms of anti-inflammatory activity is comparable to the highest strength topical corticosteroids, while providing a faster response to therapy and effectively relieving symptoms of itching and peeling. This is confirmed by the authors’ own clinical experience and demonstrated in the clinical cases described in the article.

The most common dermatoses of athletes

Introduction and purpose The skin and subcutaneous tissue constitute the body's protective barrier. It also fulfills important physiological functions. It protects internal organs against the harmful effects of environmental factors and maintains the balance between the human body and the environment. Athlete's dermatoses are a wide group of skin diseases that may occur as a result of specific conditions to which people who practise sports are exposed. Some skin diseases are characteristic of specific sports, while others may occur regardless of the type of physical activity performed. Mechanical damage to the epidermis, excessive humidity, contact with pathogens and exposure to various environmental factors play a key role in the development of these diseases. Regular dermatological check-ups are crucial for identifying and treating skin lesions and preventing mass infections caused by infectious agents. The study discusses the most common dermatoses in athletes, including fungal, bacterial and viral infections, contact dermatitis and dermatoses caused by mechanical and environmental factors. Materials and methods The literature included in the PubMed, BioMed Central and Polish Medical Platform databases is searched by means of the words such as dermatosis, sport, skin, fungal, bacterial, viral infection, contact dermatitis. Quoted sources in selected works were also used. ConclusionsMany factors can have a harmful effect on the skin, negatively affect its function as an integral barrier of the body and, consequently, cause the development of dermatoses, which are quite common among athletes due to frequent contact with sweat, clothing, sports equipment and the environments in which they train. Prevention is an important element in minimizing the risk of skin problems and this is key to maintaining health and continuing physical activity.

The maximum number of dermatosis was seen in the months of summer. Conclusion: Infectious diseases pose a major burden to skin health of most of the population suffering from dermatological problem. Fungal infections and scabies are treatable but very common diseases contributing in burden of dermatological disorder in population presenting to hospitals.

A study of autologous serum therapy in patients of chronic urticaria at a tertiary care center in western India

Background: Chronic urticaria (CU) is a common and troublesome dermatosis for patients. Approximately 30-50% of patients with CU have an autoimmune basis for their condition, as shown by a positive skin test for ASST, this subgroup is known as Autoreactive chronic urticaria. autologous serum therapy (AST) is considered a potential curative for this auto-reactive subgroup. Our study aimed to find out the efficacy of AST in both ASST positive and ASST negative CU patients. Methods: A cohort of 100 patients of CU were prospectively analyzed for incidence of ASST (+) patients out of total and efficacy of autologous serum injections for sequential 6 weeks in both ASST (+) and ASST (-) CU patients. The response of AST was recorded by the urticaria total severity scale (TSS) every week for 6 weeks and at 18 weeks. Results: The mean baseline TSS in the ASST (+) group was 12.14±1.66 and in the ASST (-) group was 11.77±1.45 (p-value- 0.5). The mean TSS at 18 weeks in the ASST (+) group was 1.30±1.51 and in the ASST (-) group was 2.17±2.02 (p-value-0.151). At 18 weeks of treatment, complete clearance was present in 44.6% of the ASST (+) group and 31.4% in the ASST (-) group (p value-0.151). Conclusions: AST can be considered as a first line of treatment, in patients of CU irrespective of the results of ASST, which is cost-effective and has long-lasting effects.

Prevalence of dermatoses in geriatric singaporeans in the community - a cross-sectional study

BackgroundLittle is known about the prevalence of dermatoses in “skin-well” geriatric Singaporeans. We aim to identify the prevalence of dermatoses and their associations within the geriatric population in Singapore, and to understand the distribution of dermatological encounters presenting to primary care physicians, and the resultant referral behaviour.MethodsA joint quantitative-qualitative study was performed across 8 months. Patients aged 65 years and above who visited a local polyclinic for management of non-dermatological chronic diseases were recruited. They were administered questionnaires, and underwent full skin examinations. Online surveys were disseminated to polyclinic physicians under the same healthcare cluster.Results201 patients and 53 physicians were recruited. The most common dermatoses identified in patients were benign tumours and cysts (97.5%), and asteatosis (81.6%). For every 1-year increase in age, the odds of having asteatosis increased by 13.5% (95% CI 3.4–24.7%, p = 0.008), and urticarial disorders by 14.6% (95% CI 0.3–30.9%, p = 0.045). Patients who used any form of topical preparations on a daily basis had higher odds of having eczema and inflammatory dermatoses (OR 2.51, 95% CI 1.38 to 4.56, p = 0.003). Physicians reported dermatological conditions involving 20% of all clinical encounters. Eczema represented the most commonly reported dermatosis within the first visit. 50% of dermatology referrals were done solely at the patient’s own request.ConclusionThe prevalence of dermatoses in the elderly in Singapore is high, especially asteatosis. Prompt recognition by the primary healthcare provider potentially prevents future morbidity. Outreach education for both primary care physicians and the general public will be key.Ethics approvalNational Healthcare group (NHG) Domain Specific Review Board (DSRB), Singapore, under Trial Registration Number 2020/00239, dated 11 August 2020.

A Clinico-Histopathological Study of Nail Dermatoses in a Tertiary Care Hospital.

Introduction Nail disorders account for an important component of all dermatological conditions.Nail abnormalities can result from local pathology or systemic diseases. Pathologies can lead to pain and impaired fine touch and are aesthetically distressing. Clinical assessment of nail pathologies is seldom accurate; moreover, the limited available investigative modalities make it difficult to correctly diagnose the disorders. Nail biopsies provide crucial histological information, especially for nail-limited dermatoses, though they are infrequently used and technically challenging. Proper biopsy techniques are vital to avoid complications like nail dystrophy and to ensure accurate diagnoses and effective treatments. Materials and methods A cross-sectional and observational study was conducted in the Dermatology Department of a tertiary care hospital in Maharashtra from November 2022 to July 2024, involving 51 patients aged 8-80 years with undiagnosed nail dermatoses. Patients with bleeding disorders, anesthesia allergies, and peripheral vascular diseases were excluded. Ethical clearance and written consent were obtained. In the case of pediatrics, patients' parental consent was obtained. Observation and results The age of the patients ranged from eight to 74 years, with a mean age of 38.04 years. The most affected age groups were 20-29 and 30-39 years old. Nineteen (37%) were manual laborers, followed by 10 (20%) students and nine (18%) professional workers. Symptoms lasted from one month to eight years, with a mean duration of 16.65 months. The most common dermatoses diagnosed clinically were as follows: 18 (35.3%) were onychomycosis, 16 (31.4%) were psoriasis, and eight (15.7%) were lichen planus. However, on histopathology, 20 (37.2%) were onychomycosis, followed by 16 (31.4%) of psoriasis, and eight (15.7%) were lichen planus. Conclusion This study highlights the critical role of nail biopsies in diagnosing nail disorders, particularly among middle-aged males who were manual laborers by occupation. It underscores the importance of combining clinical and histopathological approaches to accurately diagnose and manage, advocating for continued research and collaboration to improve patient outcomes.

What's the Impact of Safety Footwear on Workers Concerning Foot-Related Problems? A Systematic Review.

This study aims to assess the impact of safety footwear (SF) on workers concerning foot-related problems, especially regarding discomfort, foot pain, and skin lesions. A literature search of PubMed, Embase, Scopus, and Cochrane databases was performed according to PRISMA guidelines. Studies reporting foot-related problems in workers wearing SF were included. Exclusion criteria included non-English papers, reviews, laboratory and animal studies, expert opinions, letters to the editor, and grey literature. The quality assessment was performed using the Newcastle-Ottawa Scale. Descriptive statistic was used to present data. The initial search results yielded 483 articles; 7 articles were included in the review process. Despite the extensive variety of SF, all studies consistently reported symptomatic discomfort and pain. The discomfort factors included heat, sweating, heaviness, and footwear flexibility, with primary issues in the toes, toecaps, or metatarsal-toe crease region. The pain prevalence ranged from 42.3% to 60.8% in various anatomical regions. Irritant Contact Dermatitis was the most common (97.9%) foot dermatosis, but other foot lesions were reported: dry skin (30.2%), calluses (30%), hard nails (28%), corns (27%), and blisters. Current SFs are designed to comply with safety regulations but are influenced by the frequent occurrence of discomfort and foot problems. The literature review identified weaknesses in certain design features. Recommendations have been proposed to improve SF development. These include addressing issues such as the selection of specific types and designs of SF based on task performance and the working environment, footwear weight, and breathable materials for moisture permeation. Considerations should also encompass distinct sizing for an optimal fit, insole application, especially for prolonged standing users, and education programs to prevent foot-related issues.

Comprehensive considerations for dermatologists: the application of FDG-PET in evaluating cutaneous lesions in pediatric Langerhans cell histiocytosis.

Langerhans cell histiocytosis (LCH) is a complex disorder characterized by the clonal proliferation of Langerhans cells, primarily affecting children and adolescents. This condition exhibits a wide spectrum of clinical presentations, necessitating a multidisciplinary approach for diagnosis, treatment, and follow-up. Cutaneous manifestations of LCH are significant, mimicking common dermatoses and posing diagnostic challenges. [18F]Fluorodeoxyglucose-Positron Emission Tomography (FDG-PET) has emerged as an important tool in the evaluation of pediatric LCH, offering insights into disease activity, extent, and therapeutic response. Moreover, FDG-PET provides a non-invasive means to distinguish between active LCH skin lesions and other dermatological conditions with similar clinical appearances, enhancing diagnostic accuracy and aiding in disease monitoring. This educational review summarizes the utility of nuclear imaging techniques, with a focus on PET scans, in the diagnosis and management of cutaneous pediatric LCH. A comprehensive literature search identified seven relevant articles, including retrospective studies and case reports. These studies highlight the efficacy of FDG-PET in localizing active LCH skin lesions, monitoring disease activity, and guiding treatment decisions. FDG-PET represents a valuable imaging modality for dermatologists, oncologists, and pediatricians managing pediatric LCH patients with cutaneous involvement. This non-invasive technique contributes to improved diagnostic accuracy and facilitates early intervention, ultimately enhancing patient care and outcomes.

Immunophenotyping and viral studies in pityriasis lichenoides et varioliformis acuta lesions.

The underlying pathogenesis of pityriasis lichenoides et varioliformis acuta (PLEVA) remains unclear, although immunologic injury and viral etiology have been suggested. To evaluate and expand the immunophenotype of PLEVA and to search for possible viral pathogens. Formalin-fixed, paraffin-embedded specimens of 20 patients with PLEVA and 9 patients with common inflammatory dermatoses (ID) were studied for immunophenotyping and for human herpesvirus (HHV) 1 and 2, cytomegalovirus (CMV), HHV-8, parvovirus B19, and Epstein-Barr virus (EBV) immunohistochemistry. The presence of HHV-6, HHV-7, and enteroviruses was assayed molecularly. The numbers of CD8+ T cells and T-cell intracellular antigen-1 (TIA-1)+ cells were statistically significantly higher in PLEVA compared to the ID group. Immunohistochemistry for human HHV-1 and HHV-2, CMV and HHV-8, parvovirus B19, and in situ hybridization for EBV were all negative. There was molecular evidence for HHV-7 in only one PLEVA case (5%). Molecular studies for HHV-6 and enterovirus involvement were negative in all the PLEVA specimens. The predominant T-cell infiltrate in PLEVA is dominated by CD8+ cells, and by increased numbers of TIA1+ cells, which may indicate a cytotoxic T-cell damage to the epidermis. Viral presence was not detected.

Objective: Estimate the prevalence of dermatological manifestations in Mexican patients with common variable immunodeficiency. Methods: Cross-sectional and retrospective study, based on the analysis of records of patients with a diagnosis of common variable immunodeficiency, treated at the Siglo XXI National Medical Center (Mexican Social Security Institute), according to the criteria of the European Society of Immunodeficiencies (ESID). and of which only 3 had a genetic diagnosis with the following mutations: IRF2, CTLA4 and PIK-3, belonging to the Immunodeficiency Clinic of the National Medical Center Siglo XXI (IMSS), to evaluate dermatological manifestations, review of laboratory tests: IgA, IgM, IgG and type of replacement therapy with Immunoglobulin. The statistical analysis was carried out with the SPSS program; Descriptive statistics were used to analyze the data, according to the type of variable to be analyzed. Results: 36 patients were included, of which 55.5% were women; with median age 34 years (18-94). The prevalence of dermatological manifestations was 70% (n = 25). 30.5% had a history of infectious dermatosis and 39.5% had a history of non-infectious dermatosis. The most common dermatosis was irritant contact dermatitis in 13.8% of patients. All received replacement therapy with human immunoglobulin, 33.3% intravenously and the rest subcutaneously. Conclusions: Common variable immunodeficiency is an inborn error of immunity, with different clinical manifestations in various organs and systems (the skin is one of these). Dermatological manifestations are not usually described in patients with common variable immunodeficiency; However, it is important to identify them due to their relationship with certain complications (increased risk of superinfection), due to skin disruption and biological therapies. Keywords: Antibody immunodeficiency; Common variable immunodeficiency; skin diseases.

Causal associations between psoriasis, eczema, urticaria, and mental illness: A bidirectional Mendelian randomization study of the European population.

Observational studies have reported a relationship between multiple common dermatoses and mental illness. To assess the potential bidirectional causality between 3 skin disorders (psoriasis, eczema, and urticaria) and 4 psychiatric disorders (bipolar disorder, schizophrenia, major depressive disorder, and anxiety) in the European population, we used Mendelian randomization (MR) analysis, which provides definitive evidence for causal inference. Eligible single nucleotide polymorphisms were screened for dermatological and psychiatric disorders using a genome-wide association study database. We conducted bidirectional, 2-sample MR analysis using instrumental variables related to psoriasis, eczema, and urticaria as exposure factors, and bipolar disorder, schizophrenia, major depression, and anxiety as outcomes. Reverse MR analysis with bipolar disorder, schizophrenia, major depression, and anxiety as exposure and psoriasis, eczema, and urticaria as outcomes were also performed, and the causality was analyzed using inverse-variance weighting (IVW), MR-Egger, and weighted median methods. To thoroughly assess causality, sensitivity analyses were conducted using the IVW, MR-PRESSO, and MR-Egger methods. The results showed that bipolar disorder increased the incidence of psoriasis (odds ratio = 1.271, 95% confidence interval = 1.003-1.612, P = .047), heterogeneity test with Cochran Q test in the IVW showed P value > .05, (P = .302), the MR-Pleiotropy and MR-PRESSO (outlier methods) in the multiplicity test showed P value > .05, (P = .694; P = .441), and MR-Pleiotropy evidence showed no apparent intercept (intercept = -0.060; SE = 0.139; P = .694). Major depression increased the risk of eczema (odds ratio = 1.002, 95% confidence interval = 1.000-1.004, P = .024), heterogeneity test showed P value > .05, (P = .328), multiplicity detection showed P value > .05, (P = .572; P = .340), and MR-Pleiotropy evidence showed no apparent intercept (intercept = -0.099; SE = 0.162; P = .572). Sensitivity analyses of the above results were reliable, and no heterogeneity or multiplicity was found. This study demonstrated a statistically significant causality between bipolar disorder and psoriasis, major depression, and eczema in a European population, which could provide important information for physicians in the clinical management of common skin conditions.

Atopic dermatitis in women: special considerations in the childbearing years.

Atopic dermatitis (AD) is one of the most common inflammatory dermatoses in adults. Women are disproportionately impacted by AD and report significant impacts on quality of life compared to men. Given the absence of formal guidelines for the treatment of AD in women of childbearing age, we will review special considerations for treating women of childbearing age with AD to ensure consistent care and optimal outcomes for these patients. PubMed and Google Scholar databases were searched for relevant articles from database inception through May of 2023. There are several treatments including topical therapies, systemic therapies, and phototherapy that are considered safe during preconception, pregnancy and breastfeeding. Given the negative consequences of uncontrolled AD for both the mother and the unborn baby, the risks and benefits of potential therapies should be reviewed with all women of childbearing age suffering from AD. The gold standard in recommending therapies is randomized controlled trials; however, pregnant and lactating women are often excluded from these trials. Through shared decision-making between the dermatologist, obstetrician, and patient, the risks and benefits of any therapy should be thoroughly discussed and considered with all women of childbearing age, to optimize care and outcomes for this unique population.

Atopic dermatitis: the role of care products in common dermatosis in pediatric practice

Efficacy and safety of the combined drug (5% benzoyl peroxide / 1% clindamycin) in the treatment of acne: results of an open randomized comparative clinical study

Background. Acne is one of the most common dermatoses, the presence of which significantly reduces the quality of life of patients. For patients with inflammatory, comedonal or combined acne, the external use of fixed combinations is a first-line therapy. Aims. To study the efficacy and safety of the Zerkalin Intensive (benzoyl peroxide + clindamycin) in the treatment of acne in comparison with the Effezel (adapalene + benzoyl peroxide). Methods. An open comparative clinical study included 60 patients with acne of varying severity: group 1 — 30 patients received therapy with Zerkalin Intensive, group 2 — 30 patients received therapy with Effezel 1 time a day in the evening. The effectiveness of therapy was evaluated 2 weeks, 1, 2 and 3 months after the start of treatment. Results. After 1 month of therapy, there was a significant improvement (resolution of elements by at least 70%) in 9 (30%) patients of the group 1 and in 9 (30%) patients of the group 2 (p = 1.000); improvement (decrease in the severity of the pathological process by at least 25%) — in 12 (40%) and 18 (60%) patients, respectively (p = 0.106). After 2 months of using Zerkalin Intensive and Effezel, complete resolution of rashes was observed in 11 (36.7%) and 6 (20%), respectively (p = 0.395); significant improvement in 13 (43.3%) and 11 (36.7%) patients (p = 0.628); improvement in 6 (20%) and 13 (43.3%), respectively. After 3 months complete resolution of rashes was observed in 24 (80%) patients of the group 1 and in 12 (40%) patients of the group 2 (p = 0.088); significant improvement in 5 (16.7%) and 11 (36.6%) patients (p = 0.236); improvement in 1 (3.3%) and 7 (23.3%) patients, respectively. Against the background of the use of Effezel, 20 (66.7%) patients showed the appearance of slight dry skin and redness. No side effects were detected when using the Zerkalin Intensive. Conclusions. A comparable high efficiency of Zerkalin Intensive and Effezel in acne therapy has been established. Use of Zerkalin Intensive made it possible to achieve the onset of a full clinical effect and a significant improvement in the clinical picture in a larger number of patients and in a shorter time.

Perioral dermatitis: nuances of the clinical picture and therapy in different age periods

Perioral dermatitis is a common dermatosis that predominantly affects women aged 25–40 but is also observed in children and adolescents. The distinct localization of this condition in the perioral, perinasal, and periocular zones contributes to apparent psycho-emotional distress, markedly impairing patients’ quality of life. Perturbations in the skin biotope, local immune dysregulation, and topical glucocorticosteroid use are among the primary etiological factors. Effective management involves addressing causative factors, discontinuation of topical steroids, adopting gentle skincare practices, and employing localized treatments like metronidazole, pimcrolimus, and activated zinc pyrithione. Maintenance therapy may be warranted in select cases. The purpose of this work is to review the current literature on the problem and to present original clinical observations concerning the utilization of activated zinc pyrithione in treating patients with this condition. The article presents the results of the use of topical activated zinc pyrithione in patients spanning various age groups and exhibiting diverse degrees of perioral dermatitis severity. Significant clinical evidence substantiates the remarkable efficacy and safety profile of activated zinc pyrithione in managing perioral dermatitis, both as a standalone therapeutic modality and as an integral component of combination therapy. The use of activated zinc pyrithione in the treatment of perioral dermatitis emerges as an efficacious and secure approach for treating mild to moderate forms of the condition.
