The Comparative Effects of Monotherapy with Topical Minoxidil, Oral Finasteride, and Topical Finasteride in Postmenopausal Women with Pattern Hair Loss: A Retrospective Cohort Study.

Introduction: Oral finasteride and topical minoxidil are long-standing androgenetic alopecia (AGA) treatments; topical finasteride is a more recent medicine. Few studies have compared their therapeutic effects in postmenopausal women. We compared the therapeutic impact of topical finasteride (1-4 sprays of 0.25% topical finasteride solution daily for 12 months), oral finasteride (2.5 mg oral finasteride once daily for 12 months), and topical minoxidil (1 mL of topical minoxidil 5% twice daily for 12 months) in postmenopausal women with AGA. Methods: We conducted Bayesian network meta-analyses of individual patient-level data insofar as four clinically relevant endpoints, namely, 12-month change in (1) total hair density, (2) hair diameter, (3) clinical photographs, and (4) patients' opinion of efficacy. Data were obtained through medical charts. Regimens' surface under the cumulative ranking distribution (SUCRA) values and relative effects - as per odds ratios - were computed. Results: As per SUCRA, the most and least effective regimens - across the four outcomes - were oral finasteride, and topical finasteride, respectively; however, no significant statistical differences were found (i.e., p > 0.05). Conclusion: Oral finasteride is ranked more effective than the topical forms of minoxidil and finasteride; however, more studies are needed to confirm this result.

Isotretinoin as a promising option in the treatment of facial papules of frontal fibrosing alopecia.

Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia characterized by hairline recession, pruritus, and facial papules (FP). Various therapies are used to stabilize disease activity and induce remission. However, FP of FFA is resistant to treatment in many cases. In this review, we searched the PubMed and Google Scholar databases to screen the published literature on treatment options for FP in the context of FFA. Overall, 12 studies were included in this review. Available literature suggests a noticeable improvement in resistant-to-treatment FP in FFA patients with oral isotretinoin. The available evidence is limited and is derived from retrospective studies and case reports/series. Systemic isotretinoin can be considered a promising therapeutic regimen for treating resistant-to-treatment FP of FFA patients. However, more extensive, well-designed studies are necessary for confirmatory evidence.

Dermoscopic Nail Changes in Psoriasis, Lichen Planus, and Lichen Striatus.

Background: Onychoscopy is a noninvasive method helpful in diagnosing nail disorders. The aim of the study was to review literature on the usability of onychoscopy in nail psoriasis, nail lichen planus, and nail lichen striatus. Summary: Onychoscopic features of nail psoriasis are pitting, onycholysis with erythematous border, salmon patches, splinter hemorrhages, dotted vessels in lateral and proximal folds, and hyponychium. Onychoscopic features of nail lichen planus are onychorrhexis, onycholysis, longitudinal melanonychia, and red lunula. The literature on the usability of onychoscopy in nail lichen striatus is scarce. Keynotes: Onychoscopy facilitates evaluation of nail abnormalities compared to the clinical examination. Lunular alterations, salmon patches, erythematous border of onycholysis as well as splinter hemorrhages in nail psoriasis are better visualized with onychoscopy compared to the naked eye. Onychoscopy enhances detection of melanonychia, dyschromia, and lunular changes in nail lichen planus. Onychoscopic features are different in fingernails and toenails.

Onychoscopy (nail dermoscopy) is a noninvasive method used in diagnosing of nail disorders. In this review, we evaluated if onychoscopy may be helpful in diagnosing inflammatory nail disorders such as psoriasis, lichen planus, and lichen striatus. Nail psoriasis can be characterized with the presence of pitting, salmon patches, splinter hemorrhages, onycholysis with or without erythematous border and dilated vessels in the hyponychium on onychoscopy. Onychoscopy of nail lichen planus shows the presence of longitudinal ridging and splitting (onychorrhexis), splinter hemorrhages, longitudinal melanonychia as well as red lunula (distal part of nail matrix). The data on onychoscopy in nail lichen striatus are scarce. Onychoscopy is a helpful tool in visualization of nail abnormalities, with most of the features better visualized with onychoscopy compared to the naked eye.

Trichoscopy of Discoid Lupus Erythematosus in the Black Scalp: A Literature Review.

Discoid lupus erythematosus (DLE) is the most common type of chronic cutaneous lupus erythematosus. It is more frequent in adult women, particularly black race. Scalp DLE has an earlier onset and a more severe clinical course in black patients compared to Caucasians. Nevertheless, studies on this population remain scarce. The aim of this study was to review the literature and summarize the most frequent trichoscopic findings of scalp DLE among patients with a higher phototype. The main trichoscopic findings of DLE on black scalp are interruption of the honeycomb pattern, reduction, or absence of pinpoint white dots, keratotic follicular plugs and peripilar casts, blue-gray dots in a speckled pattern, and large tortuous arboriform vessels. Knowledge of these and other changes enables an early diagnosis of these individuals, preventing cicatricial sequelae and reducing its impact on quality of life.

Skin Malignancies Due to Anti-Cancer Therapies.

Skin cancers involve a significant concern in cancer therapy due to their association with various treatment modalities. This comprehensive review explores the increased risk of skin cancers linked to different anti-cancer treatments, including classic immunosuppressants such as methotrexate (MTX), chemotherapeutic agents such as fludarabine and hydroxyurea (HU), targeted therapies like ibrutinib and Janus Kinase inhibitors (JAKi), mitogen-activated protein kinase pathway (MAPKP) inhibitors, sonic hedgehog pathway (SHHP) inhibitors, and radiotherapy. MTX, a widely used immunosuppressant in different fields, is associated with basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), and cutaneous melanoma (CM), particularly at higher dosages. Fludarabine, HU, and other chemotherapeutic agents increase the risk of non-melanoma skin cancers (NMSCs), including cSCC and BCC. Targeted therapies like ibrutinib and JAKi have been linked to an elevated incidence of NMSCs and CM. MAPKP inhibitors, particularly BRAF inhibitors like vemurafenib, are associated with the development of cSCCs and second primary melanomas (SPMs). SHHP inhibitors like vismodegib have been linked to the emergence of cSCCs following treatment for BCC. Additionally, radiotherapy carries carcinogenic risks, especially for BCCs, with increased risks, especially with younger age at the moment of exposure. Understanding these risks and implementing appropriate screening is crucial for effectively managing patients undergoing anti-cancer therapies.

Enhanced Insights into Frontal Fibrosing Alopecia: Advancements in Pathogenesis Understanding and Management Strategies.

Frontal fibrosing alopecia (FFA) represents a distinctive form of primary lymphocytic scarring alopecia characterized by fronto-temporal hair recession and eyebrow hair loss. While predominantly affecting postmenopausal women, FFA also occurs in women of reproductive age and men, with variations observed across different ethnic groups. Genetic predisposition, environmental factors and inflammatory pathways contribute to its pathogenesis, with evolving diagnostic criteria enhancing accuracy. FFA treatment lacks standardization, encompassing topical, systemic and physical therapies, while hair transplantation remains a temporary solution. This article reviews the current understanding of FFA, aiming to provide clinicians with updated insights for its management.

Symmetrical cutaneous rash in two women.

Symmetrical drug-related intertriginous and flexural exanthema, commonly known as "baboon syndrome" due to its typical involvement of the gluteal area, is an erythematous symmetrical rash associated with systemic drug administration.

Current Diagnostic and Therapeutic Practices in Alopecia Areata in Two Mediterranean Countries: A Survey-Based Study.

INTRODUCTION: Alopecia areata (AA) affects approximately 2% of the general population and is associated with significant psychosocial morbidity and poor health-related quality of life. Despite the high incidence of the disease the available clinical practice guidelines to help clinicians and improve patients' care are very poor and of a low methodological quality, as compared to other high-burden dermatoses. The aim of this survey is to capture the current clinical practice in AA management, as performed by dermatologists, in two Mediterranean countries to identify potential disparities and gaps in diagnosis and treatment. METHODS: A 50-item questionnaire was created in the English language and then translated into Greek and Italian language and sent to the Greek and Italian dermatologists via email. RESULTS: A total of 490 dermatologists from Italy and 234 from Greece participated in the survey. The diagnosis of AA is usually based on history and clinical examination, supported by trichoscopy. The rate of use of severity scores and scales to evaluate impact on quality of life by dermatologists was low. Treatment of patchy AA, in both adult and pediatric populations, is based on use of topical steroids as first-line treatment. Results on special site involvement (eyebrows, beard, and ophiasis), chronic cases, and the pediatric population highlight extreme heterogeneity in treatment approach. CONCLUSIONS: Our results highlight that management of AA, in terms of diagnosis and treatment, is still challenging.

Management of cutaneous adverse events caused by antineoplastic therapies: a single-center experience.

INTRODUCTION: Cutaneous adverse events can occur in patients treated with antineoplastic treatments, albeit their incidence has not been defined yet. The clinical presentation of CAEs related to anticancer treatments can vary. The purpose of our study is to characterize skin toxicities during oncological treatments, manage such adverse events to improve patients' quality of life, and ensure therapeutic adherence. METHODS: We conducted a single-center prospective study which provided the enrollment of all patients referred to the Skin Toxicity Outpatient Clinic for the occurrence of cutaneous adverse events secondary to an ongoing antineoplastic treatment, between July 2021 and June 2023. We analyzed clinical features, and we described our therapeutic approach. RESULTS: Based on the type of drug assumed, chemotherapy-induced skin toxicity in 24 (38.7%) of the 62 evaluated patients, target therapies in 18 (29.0%), CDK4/6 cyclin inhibitors in 12 (19.4%), and immunotherapy in 6 (9.7%), while skin adverse events secondary to hormone therapy were seen in two patients. The most common cutaneous adverse event in our experience was rosaceiform rash of the face, followed by eczematous rash, hand-foot syndrome, and folliculitis. CONCLUSION: The present study is aimed at describing the variability and heterogeneity of clinical manifestations of different pharmacological classes used in oncological patients, as well as the different pathogenesis of skin damage. Chemotherapy very frequently causes skin toxicities that are often underestimated by clinicians. Their adequate recognition and optimal treatment lead to total recovery and allow better adhesion to chemotherapy.

Automated Prediction of Photographic Wound Assessment Tool in Chronic Wound Images.

Many automated approaches have been proposed in literature to quantify clinically relevant wound features based on image processing analysis, aiming at removing human subjectivity and accelerate clinical practice. In this work we present a fully automated image processing pipeline leveraging deep learning and a large wound segmentation dataset to perform wound detection and following prediction of the Photographic Wound Assessment Tool (PWAT), automatizing the clinical judgement of the adequate wound healing. Starting from images acquired by smartphone cameras, a series of textural and morphological features are extracted from the wound areas, aiming to mimic the typical clinical considerations for wound assessment. The resulting extracted features can be easily interpreted by the clinician and allow a quantitative estimation of the PWAT scores. The features extracted from the region-of-interests detected by our pre-trained neural network model correctly predict the PWAT scale values with a Spearman's correlation coefficient of 0.85 on a set of unseen images. The obtained results agree with the current state-of-the-art and provide a benchmark for future artificial intelligence applications in this research field.

Ultrasound Features of Onychopapilloma at High-Frequency and Ultra-High Frequency.

OBJECTIVE: This study aimed to identify the sonographic features of pathologically confirmed onychopapilloma cases. METHODS: High-frequency up to 24 MHz and ultra-high frequency-ultrasound up to 71 MHz examinations were performed and correlated with their clinical and pathologic presentations. RESULTS: Twenty-two cases met the criteria. Clinical presentations revealed longitudinal erythronychia in 63.3% of cases. The ultrasound examinations identified a hypoechoic band in the nail bed (86.3%), nail plate abnormalities including upward displacement (68.2%) and thickening (68.1%), focal hyperechoic focal spots on the nail plate (50%) and irregularities of the ventral plate (33.3%). Color Doppler imaging showed no hypervascularity of the nail bed in all studies. These findings correlate with histological characteristics of onychopapilloma, including nail bed acanthosis, papillomatosis, and layered hyperkeratosis. Recurrence occurred in two cases after surgery, with tumors showing proximal extension in the matrix region on ultrasound not evident during clinical examination. CONCLUSION: High-frequency and ultra-high-frequency can provide anatomical information in onychopapilloma that could enhance understanding and management.
