#1
REVIEW
Anders Vahlquist, Judith Fischer, Hans Törmä
Hereditary ichthyoses are due to mutations on one or both alleles of more than 30 different genes, mainly expressed in the upper epidermis. Syndromic as well as nonsyndromic forms of ichthyosis exist. Irrespective of etiology, virtually all types of ichthyosis exhibit a defective epidermal barrier that constitutes the driving force for hyperkeratosis, skin scaling, and inflammation. In nonsyndromic forms, these features are most evident in severe autosomal recessive congenital ichthyosis (ARCI) and epidermolytic ichthyosis, but to some extent also occur in the common type of non-congenital ichthyosis...

BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by non-scarring alopecia with T-cell infiltration at the affected hair follicle. OBJECTIVE: Our aim was to study the potential link between hepatitis B virus (HBV) antigen exposure and AA. METHODS: Two pediatric patients with AA following hepatitis B vaccination were identified in a general dermatology clinic. A bioinformatics analysis and an electronic medical record (EMR) database query were performed at the University of Rochester Medical Center to identify patients with AA, coexisting viral infections, vaccinations, or interferon (IFN) therapy in order to determine if the presence of AA and these conditions was higher than in AA patients without these associated conditions or therapy...

Unwanted facial and body hair presents as a common finding in many patients, such as females with hirsutism. With advances in laser and light technology, a clinically significant reduction in hair can be achieved in patients with light skin. However, in patients with darker skin, Fitzpatrick skin types (FST) IV-VI, the higher melanin content of the skin interferes with the proposed mechanism of laser-induced selective photothermolysis, which is to target the melanin in the hair follicle to cause permanent destruction of hair bulge stem cells...

Birt-Hogg-Dubé syndrome (BHD) is an autosomal dominant genodermatosis with malignant potential characterized by cutaneous and extracutaneous stigmata. Aberrations in the folliculin (FLCN) gene, which is located on chromosome 17, have been discovered in individuals with this condition. Over 150 unique mutations have been identified in BHD. The skin lesions associated with this condition include fibrofolliculomas, trichodiscomas, perifollicular fibromas, and acrochordons. Extracutaneous features of the syndrome typically include the lung (spontaneous pneumothorax and cysts) and the kidney (neoplasms)...

Graft-versus-host disease (GVHD) is an immunological reaction and a frequent complication following allogeneic hematopoietic stem cell transplantation. It is associated with high mortality rates and may have a significant negative impact on the patient's quality of life, particularly in the chronic-stage setting. Many different organs can be involved, which leads to a wide range of clinical manifestations. In this context, dermatologists play a key role by diagnosing and treating GVHD from the outset since cutaneous features are not just the most common but are also usually the presenting sign...

Rosacea fulminans is a rare inflammatory condition of the central face marked by the abrupt onset of erythematous coalescing papules, pustules, nodules, and draining sinuses. Due to infrequent reporting in the literature, the pathophysiology, classification, and nomenclature of this condition remain controversial. This comprehensive review evaluated a total of 135 cases of rosacea fulminans for clinical and histopathologic features and reported treatment strategies. Patients were 91% female with an average age of onset of 31...

Pyoderma gangrenosum (PG) is a rare neutrophilic dermatosis that may be caused by an adverse drug reaction. We discuss the clinical presentation and outcomes of 52 cases of drug-induced PG reported to date in the literature. We conducted our literature search for case reports of drug-induced PG using keywords on PubMed and Medical Subject Heading (MeSH) terms on MEDLINE and EMBASE. To assess the probability that each case of PG was related to drug therapy, we used the Naranjo criteria. We identified 44 studies in the literature, with a total of 52 cases of drug-induced PG...

REVIEW
Tiago Torres, Luis Puig
Psoriasis is a chronic immune-mediated disease associated with several co-morbidities and negative impacts on a patient's quality of life. Despite the advances in biologic therapy, there are still unmet needs in the treatment of psoriasis, as current treatments are limited in terms of long-term efficacy, tolerability, safety, route of administration, and cost. Apremilast is an oral, small-molecule phosphodiesterase 4 inhibitor that works intracellularly by blocking the degradation of cyclic adenosine 3',5'-monophosphate, resulting in increased intracellular cyclic adenosine 3',5'-monophosphate levels in phosphodiesterase 4-expressing cells...

Approximately one in four patients treated with anti-TNF agents (infliximab, etanercept, adalimumab, certolizumab, and golimumab) develops cutaneous adverse events, typically months to years after the initiation of treatment, with xerosis cutis, eczema (often psoriasiform), psoriasis, palmoplantar pustulosis, cutaneous infections, alopecia, and skin cancer being the most frequently encountered. The typical skin lesion of anti-tumor necrosis factor (TNF)-treated patients is orange-red psoriasiform eczema affecting the flexures, genitalia, scalp, or face, with high susceptibility to bacterial superinfection with Staphylococcus aureus...

REVIEW
Reinhart Speeckaert, Nanja van Geel
The pathophysiology of vitiligo is becoming increasingly clarified. In non-segmental vitiligo, early factors include activation of innate immunity, inflammasome activation, oxidative stress, and loss of melanocyte adhesion. Nonetheless, the main mechanism leading to non-segmental vitiligo involves an immune-mediated destruction of melanocytes. Anti-melanocyte-specific cytotoxic T cells exert a central role in the final effector stage. Genetic research revealed a multi-genetic inheritance displaying an overlap with other autoimmune disorders...

Alopecia areata (AA) is a T-cell mediated autoimmune disorder in which inflammatory cells attack the hair follicle, resulting in round, well-circumscribed patches of noncicatricial hair loss in normal appearing skin. AA affecting the beard area is well known and is referred to as AA of the beard (BAA) or AA barbae when involvement is limited exclusively to the beard. BAA has been documented in a select number of studies. We review the literature and discuss the clinical features, epidemiology, diagnosis, and treatment of BAA...

REVIEW
Maria Relvas, Tiago Torres
Psoriasis is a chronic inflammatory systemic disease associated with an important physical and physiological burden. It primarily affects the skin, but it is associated with several serious medical co-morbidities. One third of total psoriatic cases have their onset during the pediatric age, although some of them may not be diagnosed until the patient reaches adulthood. Additionally, in the pediatric age, there is an association with several medical co-morbidities; thus, an early recognition of the disease and a subsequent appropriate approach may delay or even prevent considerable co-morbidities...
