RESUMEN
Alopecia areata is an autoimmune form of non-scarring hair loss. It is usually characterized by limited areas of hair loss. However, the disease may progress to complete scalp and body hair loss (alopecia totalis, alopecia universalis). In patients with alopecia areata hair loss significantly impacts the quality of life. Children and adolescents with alopecia areata often experience bullying, including physical aggression. The disease severity evaluation tools used in clinical practice are: the Severity of Alopecia Tool (SALT) score and the Alopecia Areata Scale (AAS). A SALT score equal to or greater than 20 constitutes a commonly accepted indication for systemic therapy in alopecia areata. When using the AAS, moderate to severe alopecia areata should be considered a medical indication for systemic treatment. Currently, the only two EMA-approved medications for alopecia areata are baricitinib (JAK 1/2 inhibitor) for adults and ritlecitinib (JAK 3/TEC inhibitor) for individuals aged 12 and older. Both are EMA-approved for patients with severe alopecia areata. Other systemic medications used off-label in alopecia areata include glucocorticosteroids, cyclosporine, methotrexate and azathioprine. Oral minoxidil is considered an adjuvant therapy with limited data confirming its possible efficacy. This consensus statement is to outline a systemic treatment algorithm for alopecia areata, indications for systemic treatment, available therapeutic options, their efficacy and safety, as well as the duration of the therapy.

Self-induced nail disorders are a broad group of different clinical manifestations that share the common trait of being caused more or less voluntarily by the patient. These are distinct conditions within the clinical spectrum of onychotillomania. Most patients diagnosed with these disorders have psychiatric co-morbidities, and a multidisciplinary approach is thus highly recommended. The purpose of this review is to describe the most common clinical features encountered during daily nail consultations and to provide useful diagnostic tools and therapeutic tips for the best approach to these conditions.

Hair loss may change the quality of life since modern society considers hair an essential element in beauty definition. The most common causes of hair loss are androgenetic alopecia (AGA) and telogen effluvium (TE). AGA requires a lifetime use of minoxidil or finasteride (and sometimes they lose efficacy over the years), whereas TE has no standardized therapy available. Our study focuses on a novel topical regenerative preparation that, by mimicking autologous PRP, can safely and efficiently improve hair loss in patients affected by TE and AGA.

Background: Intravenous drug users (IVDUs) represent a very small group of patients affected by chronic wounds (CWs). Objectives: To assess the risk factors for CWs in IVDUs, to improve their treatment. Methods: A retrospective review of 7 IVDUs with CWs was performed at the Dermatology of the University of Bologna. Results: A history of 10 years of the most frequent injection was heroin in the gaiter area. The most observed comorbidities were HIV, HCV and HBV. They were treated most with an alginate with silver dressing with an average follow-up of 2.8 years. Conclusions: We would like to highlight the importance of clinical history in this type of patients and that in our experience specialized skin wounds risk assessment and management could be useful, aside from traditional compression therapy.
RESUMEN
Scalp dysaesthesia, considered a variant of the cutaneous dysaesthesia syndrome, is characterized by chronic sensory symptoms, including pruritus, pain, burning and stinging in a well-defined location, without objective findings. Its aetiology is not well elucidated and treatment options are limited, thus it can be challenging and frustrating for both patient and physician. It can be associated with lichen simplex chronicus. In this paper, we review the literature on the pathogenetic factors, diagnostic methods and therapeutic options in the management of scalp dysaesthesia. Dissociation, cervical spine disease and muscle tension seem to be the most important pathogenetic factors. Trichoscopy, reflectance confocal microscopy and biopsy are all helpful for the diagnosis of the disease. Therapies include high-potency topical or intralesional corticosteroids, capsaicin and topical anaesthetics, sedative antihistamines, tricyclic antidepressants, transcutaneous electric nerve stimulation, botulinum toxin and vitamin B12.

The non-invasive examination of the nail unit using a dermoscope is known as onychoscopy. This technique has become increasingly appreciated to facilitate the clinical diagnosis of nail disorders, opening up a valuable second front with a potential to avoid invasive diagnostic procedures. During a nail consultation, the nail unit should always be examined with the aid of a dermatoscope in all its components. The aim of this paper was to provide practical information about onychoscopy of the nail plate free edge and hyponychium, two components of the nail unit difficult to evaluate at naked eye and often forgotten, but of paramount importance.

BACKGROUND: Scalp psoriasis is often undiagnosed or inadequately treated. The patient himself underestimates the seriousness of this hair disease and consults too late to a dermatologist. OBJECTIVES: The aim of our study was to create a correlation between the clinical patterns and trichoscopy of scalp psoriasis such in a way to help the clinician to make the diagnosis and select the appropriate therapy. MATERIAL AND METHODS: We gathered all patients affected of scalp psoriasis afferent to Outpatient's hair consultation of the Department of Experimental, Diagnostic and Specialty Medicine, University of Bologna, from January 2012 to December 2018. All patients were evaluated through clinical, trichoscopic examination and a skin biopsy only in doubtful cases. We quantified the severity of the disease with several objective and subjective parameters every 4 months, up to 1 year. We recorded therapies, outcome data and quality of life. RESULTS: We collected 156 patients affected by scalp psoriasis, identifying seven clinical patterns with specific trichoscopical correlation. In the order of frequency, the clinical patterns were as follows: plaque psoriasis (with a prevalence of erythema, silver-white scales and twisted red loops vessels and red dots); thin scales (with silvery-white scales, simple red lines and signet red ring vessels); sebopsoriasis (with greasy scales, erythema with red dots, globules and twisted and bushy red loops at high magnification); psoriatic cap (with silver-white scales, erythema and polymorphic vascular pattern); pityriasis amiantacea (with yellowish adherent scales, erythema and simple red loops capillaries); cicatricial psoriatic alopecia (with erythema associated with yellowish, silver-white scales with twisted and bushy red loops capillaries) and pustular psoriasis (with 'flower shape' pustular lesions, erythema simple red loops capillaries). CONCLUSIONS: The description of different clinical patterns of scalp psoriasis and its trichoscopical correlations may help the clinician to make the diagnosis also in atypical presentations and to prescribe an adequate therapeutic regimen.

The field of hair disorders is constantly growing. The most important hair diseases are divided in non- cicatricial and cicatricial ones. Non-cicatricial alopecia are more frequent than cicatricial alopecia. The first step is to obtain a good history and physical examination. Laboratory testing is often unnecessary, while trichoscopy is fundamental for all hair diseases. Scalp biopsy is strongly suggested in cicatricial alopecia and in doubtful cases. Androgenetic alopecia, alopecia areata, telogen effluvium, trichotillomania are common causes of non- cicatricial alopecia. Frontal fibrosing alopecia, discoid lupus erythematosus, lichen planopilaris, follicullitis decalvans are some of the most common forms of cicatricial hair loss. Many treatments are available, and a prompt diagnosis is very important for the prognosis.

There are few data on the virological characterisation of patients with failure to current-generation direct-acting antivirals (DAAs), namely elbasvir/grazoprevir, sofosbuvir/velpatasvir and glecaprevir/pibrentasvir. This study aimed to characterise virological patterns in patients with failure to current DAA regimens as well as the efficacy of re-treatment. All 61 consecutive hepatitis C virus (HCV) treatment-naïve patients with failure to current DAAs from January 2018 to February 2019 were enrolled. Sanger sequencing of NS3, NS5A and NS5B proteins was performed using homemade protocols. NS5A resistance-associated substitutions (RASs) were more frequent in the 17 patients treated with sofosbuvir/velpatasvir (89.5%) and 33 patients treated with elbasvir/grazoprevir (97%) compared with the 11 patients treated with glecaprevir/pibrentasvir (18.2%) (P = 0.002 and 0.000, respectively). NS3 RASs were more often detected in the 33 patients with failure to elbasvir/grazoprevir (30.3%) than in the 11 patients treated with glecaprevir/pibrentasvir (9.1%). NS3 RASs were also detected in 12% of sofosbuvir/velpatasvir-treated patients. NS5B RASs were infrequently identified. Of the glecaprevir/pibrentasvir-treated patients, 73% did not show RASs in any HCV regions, a prevalence higher than that observed in those treated with elbasvir/grazoprevir (0%; P < 0.05) or sofosbuvir/velpatasvir (12%; P < 0.05). Of the 61 patients, 21 (34.4%) were re-treated with sofosbuvir/velpatasvir and voxilaprevir. All patients achieved sustained virological response at 12 weeks (SVR12). To our knowledge, this is one of the first real-life studies describing patients who failed current-generation DAAs; the prevalence of RASs differed according to the DAA regimen used, and the efficacy of re-treatment was high.

BACKGROUND: Trachyonychia is a nail disease characterized by longitudinal striations, ridges, fissures and/or pitting. This condition can be both idiopathic and associated with other dermatologic diseases. OBJECTIVE AND METHODS: The aim of this retrospective study was to analyse the clinical features, onychoscopy, therapy efficacy and outcome of 122 patients with trachyonychia visited at the Hair Disease Outpatient Consultations of the Dermatology Unit of the Department of Experimental, Diagnostic and Specialty Medicine of the University of Bologna, from 1988 to 2018. RESULTS: Opaque trachyonychia was the most observed type while shiny trachyonychia, less common, was present especially in milder cases. Pitting was the most frequently observed feature (80.3%), followed by koilonychia (45%) and hyperkeratosis (19.6%). Nail matrix longitudinal biopsy was performed for diagnosis confirmation in 29 cases, and spongiotic was the most common pattern. Topical therapy was prescribed in 109 patients while systemic treatments were reserved for severe cases (38 patients); 22 patients did not receive any treatment. A marked improvement in the appearance of the nails or even a total resolution was seen in 63 patients. CONCLUSIONS: Trachyonychia can occur at any age but is more frequent in children and often associated with alopecia areata. The pathological diagnosis of trachyonychia is not mandatory as the disease has generally a benign outcome. Considering the absence of pain and the high rate of spontaneous resolution, treatment is often prescribed only for cosmetic reasons or reserved for severe cases.

BACKGROUND: Erosive pustular dermatosis of the scalp (EPDS) is characterized by crusted erosions or superficial ulcerations that lead to scarring alopecia. OBJECTIVES AND METHODS: We performed a multicentre retrospective clinical study including 56 patients (29 females and 27 males, mean age 62.7) with a confirmed EPDS in order to describe epidemiology, clinical findings and therapeutic choices of this disease. RESULTS: Mechanical/chemical trauma was reported in 28.6%, a previous infection in 10.7%, a previous cryotherapy in 5.4% androgenetic alopecia in 48.2% and severe actinic damage in 25%. Trichoscopy showed absence of follicular ostia, tufted and broken hair, crusts, serous exudate, dilated vessels, pustules and hyperkeratosis. Histopathology revealed three different features, depending on the disease duration. The most prescribed therapy was topical steroids (62.5%), followed by the combination of topical steroids and topical tacrolimus (8.9%), systemic steroids (7.1%) and topical tacrolimus (5.4%). A reduction of inflammatory signs was observed in 28 patients (50%) treated with topical steroids and in all three patients treated with topical tacrolimus. CONCLUSION: The relatively high number of patients collected allowed us to identify a better diagnostic approach, using trichoscopy and a more effective therapeutic strategy, with high-potency steroids or tacrolimus, which should be considered as first-line treatment.
