Diagnosis and management of subungual and periungual verruca: A clinical review.

Nail unit verruca is the most common nail tumor encountered in clinical practice and may be highly distressing to patients due to reduced functionality, cosmesis, and stigmatization. Subungual and periungual verrucae present a challenge for treatment compared to cutaneous warts of other sites and recurrence rates are high. The risk of spread to other skin and mucosal areas inherent to all warts may be increased given location on the fingertips.

Extra-follicular cutaneous manifestations of frontal fibrosing alopecia.

Frontal fibrosing alopecia (FFA) is an inflammatory cicatricial alopecia, which is considered to be a variant of lichen planopilaris. In addition to follicular changes, FFA often presents with associated cutaneous manifestations in most patients, including lichen planus pigmentosus, implantation line hypochromia and facial papules. The objective of the present article is to provide a detailed overview of the non-follicular cutaneous clinical manifestations of FFA and discuss their impact on the diagnosis and treatment of patients with this condition.

Intradermal Botulinum Toxin A on Skin Quality and Facial Rejuvenation: A Systematic Review and Meta-analysis.

Background: Botulinum toxin A (BTxA) has gained popularity as a nonsurgical aesthetic treatment for skin rejuvenation. However, previous studies on intradermal BTxA have shown inconsistent results. This systematic review and meta-analysis with trial sequential analysis aimed to assess the efficacy and safety of intradermal BTxA for facial rejuvenation.

Differential diagnosis of pigmented nail lesions.

The diagnosis of pigmented nail lesions is a concern for both general practitioners and dermatologists, due to the possibility of indicating nail melanoma. The origin of the dark pigmentation can be either melanocytic or non-melanocytic (fungi, bacteria, or blood), and clinical evaluation alone may not be sufficient for differentiation, requiring additional exams. Onychoscopy provides valuable information prior to biopsy.

Surgical Management of Difficult Nail Glomus Tumors.

Background: Nail glomus tumor is a well-known tumor, with well-defined clinical characteristics and surgical treatment; however, some of these lesions occur in different locations and sizes with difficult surgical resolution.

Summary: Clinical and imaging tests help in the diagnosis and tumor localization.

Key Message: Adequate surgical knowledge for these cases ensures lower rates of recurrence and nail dystrophy.

Assessment of the Efficacy and Durability of IncobotulinumtoxinA in the Treatment of the Upper Face in Adult Women.

Introduction: IncobotulinumtoxinA (Xeomin®) is used in the treatment of dynamic wrinkles and the aesthetic repositioning of facial structures. The duration of its muscular effect typically extends for around 4 months. However, the residual aesthetic benefit can be observed for a longer period.

Identification of Predictors of Metastatic Potential in Paragangliomas to Develop a Prognostic Score (PSPGL).

Context: Paragangliomas (PGLs) are rare tumors in adrenal and extra-adrenal locations. Metastasis are found in approximately 5% to 35% of PGLs, and there are no reliable predictors of metastatic disease.

Objective: This work aimed to develop a prognostic score of metastatic potential in PGLs.

Role of tangential biopsy in the diagnosis of nail psoriasis.

Background: Histopathology can be crucial for diagnosis of inflammatory nail diseases. Longitudinal excision and punch biopsies are the most used techniques to obtain the tissue sample. However, there is a low clinical-histopathological correlation, besides the risk of nail dystrophy.

An Innovative Treatment Using Calcium Hydroxyapatite for Non-Surgical Facial Rejuvenation: The Vectorial-Lift Technique.

Background: The facial aging process entails alterations in the volume, shape, and texture of all skin layers over time. Calcium hydroxyapatite (CaHA) is a well-established safe skin filler with unique properties to resolve some skin alterations by stimulating neocollagenesis. The vectoral-lift (V-lift) technique targets the global repositioning of facial structures by addressing distinct anatomical injection planes.

Ankle instability in pediatric and adolescent patients diagnosed with lateral malleolus avulsion fracture: Analysis of clinical and functional outcomes of ligament injury repair surgery.

Background: Some children and adolescents can develop persistent pain and instability following inversion injuries of the ankle. In these cases, imaging exams could reveal small bone fragments distal to the lateral malleolus. For these patients, regular conservative treatment may not be successful, requiring additional management, which can include surgical treatment.

Multiple-Digit Pigmented Bowen's Disease Induced by Human Papillomavirus in an Immunocompetent Child.

Introduction: Bowen's disease is a squamous cell carcinoma in situ, the most common malignancy of the nail unit. Presenting more frequently in the fingernails, common risk factors include ionizing radiation, oral exposure to arsenic or pesticides, dyskeratosis congenita, and quite commonly diverse subtypes of HPV. We report the first case of multiple periungual pigmented Bowen's disease in a pediatric patient.

Embracing Spectrum: Celebrating LGBTQIA+ Journeys in Aesthetic Medicine: A Kaleidoscope of Identity.

Purpose: This synaptic systemised review critically examines the provision of aesthetic medical care to LGBTQIA+ (lesbian, gay, bisexual, transgender, queer or questioning, intersex, asexual, and more) individuals, assessing both the clinical practices and the educational frameworks that guide interactions with LGBTQIA+ patients in aesthetic settings.

Methods: Following PRISMA-S guidelines, a comprehensive review was conducted, initially identifying 159 potentially relevant articles. Upon stringent full-text review, 33 studies met the inclusion criteria and were subject to an in-depth thematic analysis.

Total Chemical Matricectomy With 88% Phenol: A Prospective Case Series of 37 Patients.

Background: Definitive nail dystrophies, congenital, traumatic, or acquired, affecting mainly elderly patients, may not be sufficiently managed with a periodic conservative treatment. A definitive surgical treatment may be considered an alternative method, especially in symptomatic patients.

Objective: To evaluate the effectiveness of total matricectomy with 88% phenol solution to treat some nail dystrophies, not otherwise satisfactorily managed.

Advanced Injection of Botulinum Toxin in the Nasal Muscles: A Novel Dynamic Change in Facial Expression.

Background: Among the nasal muscles, the levator labii superior alaeque nasi (LLSAN) acts as a transitional muscle that conjugates with other nasal and perinasal muscles. Thus, when treating the nasal region with Botulinum toxin (BTX), it is important to understand local nasal muscular dynamics and how they can influence the muscular dynamics of the entire face.

Methods: This is a retrospective analysis of cases treated by an injection pattern encompassing the face, including nasal muscles.

Onychoscopic characteristics of Trichophyton rubrum and Trichophyton interdigitalis fungal infections: A multicentric study.

Background: Trichophyton rubrum and Trichophyton mentagrophytes variant interdigitalis are the most frequent etiologic agents of onychomycosis. Diagnosis of certainty requires mycological examination, which often results unfeasible.

Objectives: The aim of our study is to describe pathogen specific dermoscopic features, allowing a differential diagnosis without the need for cultural examination, in order to prescribe the most appropriate treatment anyway.

Normal Trichoscopic Findings after Hair Transplantation in Androgenetic Alopecia: A Prospective Case Series.
