Clinical ABCDE rule for early melanoma detection.

Background: The ABCDE rule systematizes warning signs for malignant melanoma (MM).

Objectives: To evaluate whether the ABCDE signs are associated with early detection of MM.

Materials & Methods: Based on a retrospective study over 11.

Dermatoscopic and clinical features of congenital or congenital-type nail matrix nevi: A multicenter prospective cohort study by the International Dermoscopy Society.

Background: Congenital nail matrix nevi (NMN) are difficult to diagnose because they feature clinical characteristics suggestive of adult subungual melanoma. Nail matrix biopsy is difficult to perform, especially in children.

Objective: To describe the initial clinical and dermatoscopic features of NMN appearing at birth (congenital) or after birth but before the age of 5 years (congenital-type).

Potential of Solar UV Radiation for Inactivation of Coronaviridae Family Estimated from Satellite Data.

The pandemic COVID-19 disease affects people dramatically overall the globe by illness and death. Several strategies are applied to restrict the spread of this disease such as lockdown, adequate social distance in different activities, hand disinfection and the use of masks. Potential hazard outdoors comes from released viruses, which may remain in the air for a while and settle down afterward and contaminating surfaces.

Face masks for community use: An awareness call to the differences in materials.

CO laser treatment of a kissing nevus of the penis: an alternative solution for a rare condition.

Divided or kissing nevi are a rare clinical variant of congenital melanocytic nevi developing in adjacent areas of the skin that undergo cleavage during embryogenesis. Penile lesions are even rarer, with only few cases described in the literature. Typically, they present as two opposing dark colored macular or papular lesions on the glans and prepuce, exhibiting a mirror-image symmetry relative to the coronal sulcus.

Sun protection behaviour and skin cancer literacy among outdoor runners.

Outdoor runners have an increased risk of melanoma and non-melanoma skin cancer. The purpose of this study was to assess skin cancer literacy and sun exposure and protection behaviour among outdoor runners during training. A cross-sectional survey-based study was conducted.

Risk factors for development of new skin neoplasms in patients with past history of skin cancer: A survival analysis.

We conducted a retrospective study aiming to assess the risk, and associated risk factors, of developing subsequent skin cancers after having a first diagnosis of skin cancer. We included all patients with biopsy-proven skin cancer attending a dermatology clinic between July 2007 and July 2017. We assessed the frequency of new skin cancers, as well as potential demographic and clinical factors significantly associated with occurrence of such neoplasms, that were identified by means of a survival analysis.

Lentigo Maligna - Not Always a Face and Neck Disease of the Elderly.

Introduction: Lentigo maligna (LM) is a rare form of in situ melanoma, frequently seen as a large patch in elderly patients. The aim of this study was to assess clinical and dermoscopic features of LM.

Material And Methods: A retrospective study of LM patients presenting to our center between July 2007 and July 2017 was performed.

Sun protection in children: a behavioural study.

Background: Incidence of skin cancer is increasing worldwide and UV exposure at a young age is an important risk factor.

Objectives: To compare sun exposure-related knowledge and behaviour among children during school and holiday periods.

Material & Methods: A cross-sectional study was undertaken at 12 Oporto public primary schools.

Stevens-Johnson syndrome/toxic epidermal necrolysis and erythema multiforme drug-related hospitalisations in a national administrative database.

Background: Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) and erythema multiforme (EM) are immunologically-mediated dermatological disorders commonly triggered by drug exposure and/or other external agents. We aimed to characterise SJS/TEN- and EM-drug-related hospitalisations in a nationwide administrative database, focusing on demographic and clinical characteristics, and in the most frequently implicated drug classes.

Methods: We analysed all drug-related hospitalisations with associated diagnosis of SJS/TEN or EM in Portuguese hospitals between 2009 and 2014.

Clinical assessment of skin phototypes: watch your words!

Fitzpatrick skin phototype classification is widely used to assess risk factors for skin cancers. This skin type evaluation is easy to use in clinical practice but is not always applied as initially described, nor practiced in a standardised way. This can have implications on the results of relevant dermato-epidemiological studies.

Carbonate Buildups in the Pernambuco Basin, NE Brazil.

The Pernambuco Basin represents one of the most prominent regions for deep water oil and gas exploration off the Brazilian coast. This study aims to identify and describe the occurrence of carbonate buildups in the offshore regions of the basin. The study was based on an analysis of a set of 143 2D time-migrated seismic sections that cover the offshore region of the Pernambuco Basin.

HLA and Delayed Drug-Induced Hypersensitivity.

Delayed drug allergy reactions (DDAR) are potentially fatal. Certain human leukocyte antigen (HLA) alleles have been associated with delayed allergy reactions following the administration of particular drugs. Examples are HLA-B*57:01 (abacavir), HLA-B*15:02/HLA-A*31:01 (carbamazepine), and HLA-B*58:01 (allopurinol).

Are General Physicians Prepared for Struggling Skin Cancer?-Cross-Sectional Study.

The aim of this study is to evaluate the role of general practitioners (GP) in selecting higher risk population for skin cancer screening. GP's training was organized to examine a specific high risk population consisting mainly of fisherman and farmers in a city of North of Portugal. Health care professionals of local health units training was performed by two dermatologists 2 months before the screening.

Giant subungual glomus tumor: clinical, dermoscopy, imagiologic and surgery details.

Glomus tumor is a rare benign vascular hamartoma derived from the modified smooth muscle cells of the glomus body. Paroxysmal pain is the leading symptom. A 78-year-old woman presented at our clinic with a 50-year history of a slow growing painful purple blue tender nodule under the right fourth finger nail.

Chitosan Coated Textiles May Improve Atopic Dermatitis Severity by Modulating Skin Staphylococcal Profile: A Randomized Controlled Trial.

Background: Atopic dermatitis (AD) patients may benefit from using textiles coated with skin microbiome-modulating compounds. Chitosan, a natural biopolymer with immunomodulatory and antimicrobial properties, has been considered potentially useful.

Objective: This randomized controlled trial assessed the clinical utility of chitosan-coated garment use in AD.

Multiple minute digitate hyperkeratosis affecting the face and folds: clinical, dermoscopic, and histological report of a familial case.

A case of a generalized non-follicular digitate keratosis classified as multiple minute digitate hyperkeratosis is described with suggestive clinical, dermoscopic, and histopathogical data. The patient was a 52-year-old Caucasian woman presenting a 6-year history of multiple asymptomatic skin-colored digitate lesions, 3 to 5 mm long and 1 to 2 mm wide, distributed on the forehead, neck, and extensor surface of the arms as well as in the inframammary folds, axillae, and lower limbs, especially on the popliteal fold. She reported having a 67-year-old sister and a 39-year-old niece with an identical eruption.

Nail melanoma in situ: clinical, dermoscopic, pathologic clues, and steps for minimally invasive treatment.

Background: Nail unit melanoma (NUM) is a variant of acral lentiginous melanoma. The differential diagnosis is wide but an acquired brown streak in the nail of a fair-skinned adult person must be considered a potential melanoma. Dermoscopy helps clinicians to more accurately decide if a nail apparatus biopsy is necessary.

Functional textiles for atopic dermatitis: a systematic review and meta-analysis.

Atopic dermatitis (AD) is a relapsing inflammatory skin disease with a considerable social and economic burden. Functional textiles may have antimicrobial and antipruritic properties and have been used as complementary treatment in AD. We aimed to assess their effectiveness and safety in this setting.
