Abstract
BACKGROUND Frontal fibrosing alopecia (FFA) has become one of the most common causes of cicatricial alopecia worldwide. However, there is a lack of clear aetiology and robust clinical trial evidence for the efficacy and safety of agents currently used for treatment. OBJECTIVES To enable data to be collected worldwide on FFA using common criteria and assessment methods. METHODS A multicentre, international group of experts in hair loss was convened by email to create consensus recommendations for clinical trials. Consensus was defined at > 90% agreement on each recommended part of these guidelines. RESULTS Standardized diagnostic criteria, severity rating, staging, and investigator and patient assessment of scalp hair loss and other clinical features of FFA were created. CONCLUSIONS These guidelines should allow the collection of reliable aggregate data on FFA and advance efforts in both clinical and basic research to close knowledge gaps in this condition.

Abstract
BACKGROUND The common inflammatory scalp disorders share similar clinical manifestations, and patient work up require invasive, undesirable diagnostic procedures like biopsy to ensure correct diagnosis. Optical coherence tomography (OCT) is a non-invasive high-resolution imaging modality that has found a valuable tool to assist in the diagnose and evaluation of different skin diseases. OBJECTIVES To describe the structural and vascular dynamic OCT (D-OCT) findings of inflammatory scalp disorders including scalp psoriasis, seborrhoeic dermatitis and contact dermatitis and to compare trichoscopy and OCT features. METHODS Subjects with diagnosis of seborrhoeic dermatitis, psoriasis or contact dermatitis were enrolled in this study. OCT scans were taken on involved scalp, and the same scalp regions were evaluated by trichoscopy and compared with healthy scalp. RESULTS A total of fourteen subjects (two healthy controls, four seborrhoeic dermatitis, five psoriasis and three contact dermatitis) participated. D-OCT imaging of vascular pattern in healthy scalp and the inflammatory scalp disorders were described. D-OCT images could enhance the clinician's ability to distinguish psoriasis from seborrhoeic dermatitis by objectively detect and assess red loop density. In scalp contact dermatitis, the vessels of the deep plexus were more dilated and fewer in number than those found in seborrhoeic dermatitis. CONCLUSION Dynamic OCT provides information that more clearly elucidates changes at the level of the superficial and deep plexuses without invasively interfering with superficial structures. In the context of inflammatory scalp disorders, this is useful to discern disorders with overlapping symptoms and minimize the use of invasive biopsies to diagnose.

Microneedling for the treatment of hair loss? J Eur Acad Dermatol Venereol 2017; 32:564-569.

Abstract
Microneedling is a minimally invasive dermatological procedure in which fine needles are rolled over the skin to puncture the stratum corneum. This therapy is used to induce collagen formation, neovascularization and growth factor production of treated areas. It has been used in a wide range of dermatologic conditions, including androgenetic alopecia (AGA) and alopecia areata, among others. While there are a limited number of studies examining this therapy in the use of hair loss, microneedling has been successfully paired with other hair growth promoting therapies, such as minoxidil, platelet-rich plasma and topical steroids, and shown to stimulate hair follicle growth. It is thought that microneedling facilitates penetration of such first-line medications, and this is one mechanism by which it promotes hair growth. To date, the area most studied and with the most success has been microneedling treatment of AGA. While the current evidence does not allow one to conclude superiority of microneedling over existing standard therapies for hair loss, microneedling shows some promise in improving hair growth, especially in combination with existing techniques. This review summarizes the current literature regarding microneedling in the treatment of alopecia and calls for further studies to define a standard treatment protocol.

Abstract
Androgenetic alopecia is the most common hair loss disorder, affecting both men and women. Initial signs of androgenetic alopecia usually develop during teenage years leading to progressive hair loss with a pattern distribution. Moreover, its frequency increases with age and affects up to 80% Caucasian men and 42% of women. Patients afflicted with androgenetic alopecia may undergo significant impairment of quality of life. The European Dermatology Forum (EDF) initiated a project to develop evidence-based guidelines for the treatment of androgenetic alopecia. Based on a systematic literature research the efficacy of the currently available therapeutic options was assessed and therapeutic recommendations were passed in a consensus conference. The purpose of the guideline is to provide dermatologists with an evidence-based tool for choosing an efficacious and safe therapy for patients with androgenetic alopecia.

Abstract
BACKGROUND Pterygium inversum unguis (PIU) is characterized by the abnormal adherence of the hyponychium to the ventral surface of the nail plate. It can be both unsightly and painful, resulting in morbidity for patients. Gel polish is a popular nail cosmetic that has been reported to cause several complications. PIU may be another adverse outcome. OBJECTIVE To highlight a newly recognized adverse effect of a popular beauty technique. METHODS This retrospective and prospective case series reports 17 women who developed PIU after gel polish use. All study-related activities occurred at a University of Miami dermatology outpatient clinic. RESULTS All 17 subjects developed PIU after two to five years of gel polish application. Nine of 17 patients reported using both UVA and LED light to cure gel polish. Of the remaining eight, five used LED light only and three did not know or could not remember. All but two patients had a resolution of PIU a few weeks after switching from gel polish to regular polish manicures. CONCLUSION While it remains undiscerned whether PIU is related to chemicals present in the gel polish or to the application and/or removal process of such, patients and dermatologists should be aware of the potential risks of gel manicures.

Abstract
BACKGROUND Onychomatricoma is a benign fibroepithelial nail matrix tumor that infiltrates the nail plate leading to multiple tunneled cavities lined with matrix epithelium and filled with serum. Diagnostic features of onychomatricoma on reflectance confocal microscopy (RCM) have not been previously described. OBJECTIVE We sought to demonstrate the feasibility of using RCM to diagnose onychomatricoma. METHODS Reflectance confocal microscopy was used to evaluate four patients with onychomatricoma before tumor excision. We evaluated the affected nail and one unaffected nail of each patient with VivaScope 1500 (Lucid Inc., Rochester, NY, USA). RESULTS Reflectance confocal microscopy evaluation of onychomatricomas revealed longitudinal dark areas and bright/grey lines, forming channel like structures. The channels were outlined by bright circular lines with grey dot centers. These RCM features correlated with the pathology of the onychomatricomas within the nail plate. LIMITATIONS Proximal portion of onychomatricoma was not reach by RCM.

Abstract
BACKGROUND Correct evaluation of horizontal scalp biopsies requires accurate gross sectioning and embedding of the tissue. The most common issue during processing includes incorrect specimen bisection. OBJECTIVES To verify if (i) ex vivo assessment of scalp biopsies by contact dermatoscopy can identify the correct plane of transverse bisection as well as (ii) if using contact dermatoscopy on the glass slides can be useful to control the tissue processing and expedite sign-out. MATERIALS AND METHODS For the first aim, dermatoscopic pictures of 43 scalp biopsies were printed and shown to 10 dermatology residents not involved in the study, who were asked to identify and highlight the dermo-epidermal junction. For the second aim, dermatoscopic captions of 40 horizontal sections were evaluated in a blinded way for the size of the specimen as well as the level and plane of bisection. The agreement was investigated using Cohen's κ statistics. RESULTS Ten independent observers were able to correctly identify the dermo-epidermal junction as a brownish wavy line in 95.3% cases. The Cohen's κ statistics showed almost perfect agreement. Two independent pathologists agreed on the specimen size in all cases, on the specimen plane in 39 cases and on the specimen level on 35 cases. The Cohen's κ statistics showed almost complete agreement for the size and plane of bisection and substantial agreement for the level of section. CONCLUSION Ex vivo dermatoscopy of scalp biopsies may be a new way to decrease laboratory costs and improve turnaround time in hair pathology as this technique optimally guides the correct bisection at 1-1.5 mm below the junction. Ex vivo dermatoscopy on the slides may expedite sign out after the initial bisection.

Abstract
The pathobiology of alopecia areata (AA), one of the most frequent autoimmune diseases and a major unsolved clinical problem, has intrigued dermatologists, hair biologists and immunologists for decades. Simultaneously, both affected patients and the physicians who take care of them are increasingly frustrated that there is still no fully satisfactory treatment. Much of this frustration results from the fact that the pathobiology of AA remains unclear, and no single AA pathogenesis concept can claim to be universally accepted. In fact, some investigators still harbour doubts whether this even is an autoimmune disease, and the relative importance of CD8(+) T cells, CD4(+) T cells and NKGD2(+) NK or NKT cells and the exact role of genetic factors in AA pathogenesis remain bones of contention. Also, is AA one disease, a spectrum of distinct disease entities or only a response pattern of normal hair follicles to immunologically mediated damage? During the past decade, substantial progress has been made in basic AA-related research, in the development of new models for translationally relevant AA research and in the identification of new therapeutic agents and targets for future AA management. This calls for a re-evaluation and public debate of currently prevalent AA pathobiology concepts. The present Controversies feature takes on this challenge, hoping to attract more skin biologists, immunologists and professional autoimmunity experts to this biologically fascinating and clinically important model disease.
