Resumen: Antecedentes y objetivo: No existen datos actualizados sobre los recursos asistenciales ni la actividad médico-quirúrgica de los servicios de dermatología españoles. El objetivo de esta investigación es conocer la situación y actividad de dichos servicios durante el año 2019. Material y métodos: Estudio transversal mediante cuestionario online distribuido a los jefes de servicio de dermatología de hospitales públicos españoles. Resultados: De los 162 jefes de servicio encuestados, se obtuvo una participación del 36,4% (59/162). Se observó un déficit de personal generalizado, especialmente de dermatólogos en hospitales de complejidad media-baja. La principal causa del déficit de dermatólogos fue la ausencia de profesionales interesados. Las infraestructuras y equipamiento disponibles fueron superiores en los grandes complejos hospitalarios. La atención mixta presencial-telemática estuvo presente en más de la mitad de los centros. En el ámbito de las consultas monográficas, la de psoriasis fue la más implementada. Aproximadamente el 75% de los centros contaron con quirófanos con anestesista. Procedimientos quirúrgicos de mayor complejidad como la biopsia selectiva de ganglio centinela o la cirugía de Mohs se realizaban con mayor frecuencia en los grandes complejos hospitalarios. La hospitalización de pacientes y la presencia de dermatólogos residentes de guardia fueron igualmente más habituales en estos hospitales. La actividad docente e investigadora también se relacionó con la complejidad del hospital. Conclusiones: Nuestros resultados describen la situación de los servicios de dermatología españoles justo antes de la pandemia por COVID-19, y pueden ser útiles para la gestión clínica y para definir líneas de trabajo y áreas de mejora. Abstract: Background and objective: No recent data on health care resources and medical and surgical activity in Spanish dermatology departments are available in the literature. The aim of this study was to compile this information for 2019. Material and methods: Cross-sectional study based on an online survey sent to the heads of dermatology departments at public hospitals in Spain. Results: Of the 162 department heads contacted, 59 answered the survey (participation rate, 36.4%). General findings included a shortage of staff, especially dermatologists, in hospitals of low and medium complexity. The main reason given for the shortage of dermatologists was a lack of interested applicants. Large hospital complexes had more infrastructure and equipment. Over 50% of the departments surveyed used a combination of in-person and virtual visits. Psoriasis units were the most common specialized care units. Approximately 75% of the hospitals had operating rooms with an anesthetist. More complex procedures such as sentinel lymph node biopsy and Mohs micrographic surgery were performed more often in large hospital complexes. Hospitalization and the presence of dermatology residents working call shifts were also more common in these hospitals. Teaching and research activity differed according to hospital complexity. Conclusions: We have mapped health care resource availability and medical and surgical activity in Spanish dermatology departments prior to the COVID-19 pandemic. Our findings could be useful for improving clinical management and defining future actions and areas for improvement.

Resumen: Introducción: Existen diversas opciones terapéuticas para los hemangiomas infantiles (HI). El propranolol se utiliza con base en un ensayo pivotal. Nuestro objetivo fue describir las características del HI en la práctica clínica, incluyendo las terapias utilizadas, así como comparar las características de los pacientes tratados con propranolol y las de los pacientes del ensayo, para valorar su validez externa. Métodos: Se incluyó consecutivamente a los pacientes que acudieron a doce hospitales españoles desde junio de 2016 a octubre de 2019 (n = 601). Resultados: La edad media fue de 3,9 (DE:1,9) meses, con una ratio mujer-varón de 2:1. La mayoría de los HI fueron de tipo localizado (82%, 495), superficial (64%, 383) y ubicados en cara (25%, 157) y tronco (31%, 188). El tamaño mediano fue de 17 (RI: 10-30) x 12 (RI: 7-20) mm. Se encontraron complicaciones en 16 (3%) pacientes. Se inició tratamiento en el 52% (311) de los casos. La mayoría de los pacientes recibió timolol (76%, 237), reservándose propranolol para las complicaciones o los HI de alto riesgo. El compromiso estético fue el principal motivo de iniciar la terapia (64%, 199). Las diversas características de los pacientes y de los HI tratados con propranolol fueron similares a las del ensayo clínico pivotal, aunque 1/3 de los HI no alcanzó el diámetro mínimo para cumplir los criterios de inclusión, y no se comunicó información pronóstica importante. Conclusiones: Dado que muchos pacientes reciben tratamiento debido al compromiso estético, existe una necesidad de conocer mejor los resultados estéticos de las terapias e incrementar la evidencia sobre el uso de timolol, que actualmente es la terapia más común. El propranolol está siendo utilizado en una población generalmente similar a la del ensayo; sin embargo, esta afirmación no puede confirmarse de manera definitiva. Abstract: Background: There are several therapeutic options for infantile haemangiomas (IH). Propranolol is used according to a pivotal trial. We aimed to describe the characteristics of IH in clinical practice, including the therapies used, and to compare the characteristics of patients treated with propranolol with those of the trial to assess its external validity. Methods: Consecutive patients attending 12 Spanish hospitals from June 2016 to October 2019 were included (n = 601). Results: The mean age was 3.9 (SD:1.9) months, with a 2:1 female-to-male ratio. Most IHs were localized (82%, 495), superficial (64%, 383) and located in the face (25%, 157) and trunk (31%, 188). Median size was 17 (IR: 10-30) x 12 (IR: 7-20) mm. Complications were found in 16 (3%) patients. Treatment was initiated for 52% (311). Most patients received timolol (76%, 237); propranolol was reserved for complications or high-risk IHs. Aesthetic impairment was the main reason for starting therapy (64%, 199). Several characteristics of the patients and IHs treated with propranolol are similar to those of the pivotal clinical trial, but 1/3 of IHs did not reach the minimum diameter to meet the inclusion criteria, and important prognostic information was not reported. Conclusions: As most patients receive treatment for aesthetic impairment, there is a need to better understand the aesthetic results of therapies and to increase evidence on the use of timolol, which is currently the most common therapy. Propranolol is being used in a population generally similar to that of the trial; however, this statement cannot be definitely confirmed.

In this original research, we present the results in terms of effectiveness and safety of bimekizumab for hidradenitis suppurativa in real clinical practice. Results indicated significant improvement in all activity scores and patient-reported outcomes at week 16, including a notable decrease in mean IHS4 from 27.1 to 15.6 (p < 0.001), HS-PGA from 5.1 to 3.2 (p < 0.001), VAS pain from 8.3 to 4.7 (p < 0.001) and DLQI from 21.6 to 12.6 (p < 0.001). Bimekizumab, administered every 2 or 4 weeks, was well-tolerated with no discontinuations and no new safety concerns identified. These findings corroborate the drug's effectiveness and favourable safety profile observed in phase 3 clinical trials, supporting its use in real-world clinical practice for treating HS., (© 2024 Australasian College of Dermatologists.)

Introduction: Therapeutic burden (TB) has been identified as a potential predictor of response to biologic therapy in hidradenitis suppurativa (HS). We aim to analyze the determinants of TB in real-world clinical settings among HS patients to explain this concept and its utility as an additional tool for guiding therapeutic decision-making., Methods: We conducted a cross-sectional study including all consecutive HS patients attending a specialized HS clinic between 2017 and 2024. The primary variable was TB, defined as the cumulative sum of prior systemic treatment cycles and surgical interventions for HS. We analyzed whether sociodemographic or clinical factors were associated with a higher TB., Results: We included 557 HS patients. Of these, 50.81% were women, and the mean age was 41.87 (14.19) years. Most patients (62.30%) were referred from general dermatology consultations. The mean disease duration was 17.52 (11.51) years. Regarding disease severity, 46.50% presented with Hurley II, and 42.19% had an IHS-4 score between 4 and 10. Before their baseline visit, 9.70% of patients had received biological therapy, mostly adalimumab (88.89%). The mean TB was 2.42 (2.25) systemic medical and/or surgical interventions. Referral from general dermatology or other hospital departments, older age, longer disease duration, greater HS severity, presence of pilonidal sinus, and prior biological therapy were significantly associated with higher TB., Conclusions: Our findings suggest that TB comprehensively captures HS severity and progression factors. This metric could prove valuable in aiding decision-making for HS patients by indicating when a change in therapy might be necessary., (© 2024 The Author(s).

Introducion: The concept of a window of opportunity in hidradenitis suppurativa (HS) management suggests that early initiation of biological therapy leads to better outcomes, though its timing remains uncertain., Methods: We conducted a retrospective observational multicenter study, including consecutive patients with moderate to severe HS who initiated secukinumab treatment following prior failure with systemic antibiotics or adalimumab. Therapeutic burden was defined as the sum of previous systemic treatment cycles and previous major surgical interventions for HS. Patients were followed up for 24 weeks. Main outcomes were safety and effectiveness, assessed through the proportion of patients achieving HS Clinical Response (HiSCR) and a 55% reduction in International HS Severity Score System (IHS4-55). Additionally, potential predictors of response to secukinumab were studied. Analysis was performed on an intention-to-treat basis., Results: A total of 67 patients (33 men, 34 women) were included, with a mean age of 41.55 (11.94) years and a mean baseline IHS4 of 17.88 (11.13). The mean therapeutic burden was 6.06 (3.49). At week 24, 10.45% (7/67) of patients experienced adverse events, with three leading to treatment discontinuation. At week 24, 41.79% (28/67) of patients achieved HiSCR, and 44.78% (30/67) of patients achieved IHS4-55. HiSCR could not be calculated in 12 patients with a baseline AN count < 3. A lower therapeutic burden was significantly associated with a higher likelihood of achieving HiSCR and IHS4-55 at week 24., Conclusions: Secukinumab showed safety and efficacy in real-world patients with HS, and the inverse correlation found between therapeutic burden and treatment response supports the concept of a window of opportunity, offering insights into its timing., (© 2024.

Introduction: The recurrent nature of hidradenitis suppurativa (HS), even under maintained systemic treatment, makes it necessary to have effective local treatments; however, the response to these therapies is variable (44-81%). The application of galvanic current (GC) has demonstrated its utility in humans in treating lesions structurally similar to those of HS. With this background, the main objective of this study was to evaluate the efficacy and safety of ultrasound-guided percutaneous GC in inflamed and/or draining tunnels of HS., Methods: This was an open study (one-way repeated measures design over time). Patients were evaluated at 4 and 12 weeks after receiving GC. A combined clinical response at week 12 (absence of suppuration/inflammation on examination and clinical interview) was considered the principal variable of efficacy. Adverse effects potentially associated with GC were reported by telephone and at each visit., Results: Twenty-six patients were included, with a male/female ratio of 5:8. The mean age was 35.84 (13.14) years. At 12 weeks after the administration of GC, a complete response was achieved in 77% (20/26) of the treated lesions. No serious adverse effects were observed, and the mean procedural pain assessed by the numeric rating scale was 0.03 (0.2)., Conclusion: GC has proven to be effective and well tolerated in inflamed and draining tunnels of patients with HS., (© 2024.

Background : Dupilumab is an effective treatment for atopic Dermatitis® (AD) and it also restores skin barrier function. Nevertheless, early changes in epidermal barrier parameters related to sustained treatment response or treatment failure are not known. So, the objective of this study is to evaluate whether changes in skin barrier function after 16 weeks dupilumab treatment could predict sustained treatment response or treatment failure. Materials and Methods : A prospective observational study was conducted that included patients with AD starting dupilumab. Clinical scores, patient-reported outcome measures (PROMs), and skin barrier function parameters were assessed at baseline and after 16 weeks treatment. Patients were followed until they failed to dupilumab or until the end of the study period. Participants were divided into 2 groups: patients with treatment failure and those with sustained treatment response. Results: In total, 32 patients with AD were included in the study, with a mean age of 28.03 years (standard deviation 10.65), being 20 (60.6%) females. In total, 22 (66.7%) patients sustained dupilumab response during the study period and only 10 (33.3%) failed to treatment. After 16 weeks treatment, clinical scores were improved in both groups. Patients with sustained treatment response increased stratum corneum hydration (SCH) on noninvolved skin (34.25 arbitrary units [AU] vs 44.90AU, P  = 0.001) and on eczematous lesions (20.71 AU vs 40.94 AU, P  < 0.001) and also decreased transepidermal water loss (TEWL) on eczematous lesions (28.22 g/[m 2 ·h] vs 14.83 g/[m 2 ·h], P  = 0.002). Patients with treatment failure did not change TEWL or SCH. SCH after 16 weeks treatment on noninvolved skin (odds ratio [OR] = 0.83, P  = 0.018) and SCH after 16 weeks treatment on eczematous lesions (OR = 0.86, P  = 0.028) were related to dupilumab failure. Conclusion : SCH could be used as a predictive biomarker of dupilumab response in patients with AD.

Introduction: Distressed personality (or Type D personality, TDp) is a personality trait that has been associated with poor quality of life in patients suffering from a variety of skin diseases such as psoriasis or urticaria. To date the potential association between Alopecia areata (AA) and TDp has not been studied. The aim of this study was to compare the prevalence of TDp between patients with AA and controls, and to analyse the impact of TDp on patients with AA regarding mood status disturbances, quality of life and sexuality., Methods: Cross-sectional study includes patients suffering from mild-to-severe AA and sex- and age-matched healthy controls. Socio-demographic and clinical variables, quality of life, sexual disfunction, anxiety, depression and TDp were collected using validated questionnaires., Results: A total of 120 participants (60 patients and 60 controls) were included. Patients with AA showed higher prevalence of TDp than controls (35% vs. 15% p = 0.01), as well as higher rates of anxiety, depression and sexual dysfunction (p < 0.05). TDp was found to be linked to disease severity (p = 0.04), anxiety and depression scores (p < 0.001) and worse quality of life (p = 0.001). No relationship was found between TDp and sexual dysfunction., Discussion: Type D personality prevalence is higher in patients with AA than in controls. It is associated with higher rates of anxiety, depression and worse quality of life. Screening for this type of personality could be useful to detect patients who could benefit from additional psychological support as a complement to their medical treatment., (© 2022 European Academy of Dermatology and Venereology.)

Introduction: Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease. Biologic drugs have a key role in the long-term anti-inflammatory treatment of moderate to severe patients due to their immunomodulatory properties. The aim of this study is to evaluate the effectiveness and safety of secukinumab in patients with moderate to severe HS after 16 weeks of treatment, and to explore potential predictors of clinical response to the drug., Methods: Multicenter observational retrospective study. Patients treated with secukinumab 300 mg every 2 or 4 weeks who had completed at least 16 weeks of follow-up from nine hospitals based in southern Spain (Andalusia) were included in this study. Treatment effectiveness was assessed using the Hidradenitis Suppurativa Clinical Response (HiSCR). Information about adverse events was collected, the therapeutic burden of the patients was calculated as the summation of systemic medical treatments and surgical interventions (excluding incision and drainage) experienced until the start of secukinumab treatment., Results: Forty-seven patients with severe HS were included for analysis. At week 16, 48.9% (23/47) of patients achieved HiSCR. Adverse events were present in 6.4% (3/47) of the patients. The multivariate analysis showed that female sex and, to a lesser extent, lower body mass index (BMI) and a lower therapeutic burden were potentially associated with a higher probability of HiSCR achievement., Conclusions: Favorable short-term effectiveness and safety of secukinumab in the treatment of severe HS patients were observed. Female sex, lower BMI and a lower therapeutic burden may be associated with a higher probability of achieving HiSCR., (© 2023. The Author(s).)

Introduction: Hidradenitis suppurativa (HS) has been linked to higher cardiovascular risk (CVR) due to its inflammatory burden. There is little evidence on how biologic treatment could modify the cardiovascular risk of patients with HS. The aims of the present study were to explore the modification of CVR in patients under adalimumab treatment and to explore the potential factors associated with CVR improvement., Methods: A prospective longitudinal study was performed. A cohort of patients with HS treated with adalimumab was followed up. Carotid intima-media thickness (IMT) and other clinical and biochemical CVR factors were collected at baseline and 32 weeks after starting the treatment., Results: Twenty-seven patients with severe HS were included. Overall, there were no differences in IMT between baseline (633 μm) and 32 weeks follow-up (634 μm). However, 40.7% (11/27) of the patients presented an improvement in IMT. This group (IMT responders) had a higher prevalence of dyslipidemia, diabetes mellitus, higher HbA1c levels, consumed more tobacco, and had higher BMI at baseline. Moreover, these patients had lower IHS4 scores at baseline and tended to have a greater IMT basal value, indicating a higher burden of subclinical atherosclerosis., Conclusions: Adalimumab treatment might benefit a subset of patients with HS in terms of cardiovascular risk reduction. In light of the results of the present study patients with classical cardiovascular risk factors, and those with higher burden of subclinical atherosclerosis and with less inflammatory load, may be more likely to improve their IMT during adalimumab treatment., (© 2023.

Background: Surgery is an essential part of hidradenitis suppurativa (HS) treatment. Understanding and reducing surgical recurrence are crucial to obtaining the best results in patients' treatment., Objective: The aim of the study was to characterize surgical recurrences in a cohort of patients with HS treated with wide excision and second-intention healing., Methods: A prospective nested case-control study was conducted. A cohort of patients with HS treated with wide excision and second-intention healing was monitored for 68 weeks. The surgical procedure was classified as case (recurrence) or control (no recurrence). The type of recurrence was classified according to the elementary lesion in tunnel or abscess and inflammatory nodule (AN) recurrence. Sociodemographic and clinical data likely related to recurrence and the type of recurrence were evaluated., Results: Sixty-three patients were included, receiving a total of 82 surgical procedures. The mean age of the patients was 36.18 years, and the surgical site presented a Hurley stage II severity in 79.26% (65/82) of the interventions. Tunnel recurrence was observed in 8.5% (7/82) and AN recurrence in 15.85% (13/82) of the interventions. Obesity was associated with a higher risk of recurrence, for both tunnel and AN recurrence. Hurley III at the surgical site, a history of pilonidal sinus, and higher International Hidradenitis Suppurativa Severity Score System (IHS4) after surgery and at week 68 increased the risk of tunnel recurrence., Conclusion: We propose classifying surgical recurrence based on the elemental type of lesion. Tunnel recurrence could originate in the depth of the surgical scar and could be associated with both surgical site factors and inflammatory load. AN recurrence could originate in the borders of the surgical scar and may particularly benefit from preoperative ultrasound., (© 2022 S. Karger AG, Basel.)

Background: Previously, a new dichotomous outcome was developed, calculated as 55% reduction in the International Hidradenitis Suppurativa 4 (IHS4-55) score. It was validated in datasets of adalimumab and placebo-treated HS patients. External validation is an important aspect of clinical outcomes., Objectives: We aimed to externally validate the novel dichotomous IHS4-55 in a non-biologic treated dataset of HS patients., Methods: Data from a previously published European-wide prospective clinical study of antibiotic treatment of HS patients were used to assess the association of IHS4-55 achievement with individual reduction in inflammatory nodules, abscesses, and draining tunnels. Moreover, the associations between IHS4-55 positivity and achievement of the minimal clinically important differences (MCIDs) for Dermatology Life Quality Index (DLQI), Numerical Rating Scale (NRS) Pain, and NRS Pruritus were analyzed., Results: Data were obtained from 283 individual patients, of which 36.4% (103/283) were treated with clindamycin and rifampicin and 63.6% (180/283) with tetracyclines for 12 weeks. Achievers of the IHS4-55 demonstrated a significant reduction the counts of inflammatory nodules, abscesses, and draining tunnels (all p < 0.001). Additionally, IHS4-55 achievers had an odds ratio for achieving the MCID of DLQI, NRS Pain, and NRS Pruritus of 2.16 (95% CI 1.28-3.65, p < 0.01), 1.79 (95% CI 1.10-2.91, p < 0.05), and 1.95 (95% CI 1.18-3.22, p < 0.01), respectively., Conclusions: This study shows the external validity of the novel IHS4-55 by demonstrating a significant association between IHS4-55 achievement and a reduction in inflammatory lesion counts as well as achievement of MCIDs for DLQI, NRS Pain, and NRS Pruritus in an antibiotic-treated cohort. These findings support the use of the IHS4-55 as a novel primary outcome measure in clinical trials., (© 2023 S. Karger AG, Basel.)

Hidradenitis suppurativa (HS) is a chronic skin disease that profoundly affects patients' quality of life (QoL) and sexuality. Few data are available on the impact of HS on patients' partners. We aimed to explore the QoL and sexual function of patients' partners and the factors associated with their impairment and to compare the QoL and sexual function of single patients and those in a stable relationship. We conducted a cross-sectional study at Hospital Universitario Virgen de las Nieves (Granada, Spain) and at the Wroclaw Medical University (Wroclaw, Poland). Patients over the age of 16 years attending their scheduled follow-up and their partners, if any, were included. The Dermatology Life Quality Index (DLQI) and the Family Dermatology Life Quality Index (FDLQI) were used to estimate the QoL of patients and partners, respectively. The FSFI-6 was used to determine sexual dysfunction in women and the IIEF-5 for erectile dysfunction in men. Thirty-four single patients and twenty-eight patients in a stable relationship and their partners were included. Patients had a very large impact (DLQI 12.5 ± 7.5) and their partners a moderate impact (FDLQI 10.3 ± 7.1) in their QoL due to HS. Women with HS had a high prevalence of sexual dysfunction (13/32, 40.6%) and men of erectile dysfunction (19/30, 63.3%). Male partners also had a high prevalence of erectile dysfunction (10/17, 58.8%), while only one female partner had sexual dysfunction (1/11, 9.1%). Factors related to disease severity, intensity of symptoms and body mass index were associated with poorer QoL in partners and time of disease evolution with greater erectile dysfunction in male partners. In conclusion, HS not only profoundly affects the QoL and sexuality of patients but also of their partners. Several risk factors have been identified, which should be taken into account in the holistic approach of the disease.

Hidradenitis suppurativa (HS) is a chronic inflammatory disease of the hair follicle that has previously been associated with a higher cardiovascular risk (CVR). Although different methods have been described for CVR stratification in HS, there is little evidence about the role of hemogram indexes in CVR in HS. Given its potential convenience, the aim of this study was to assess the role of the hemogram indexes systemic immune-inflammation index (SII) and neutrophil-lymphocyte ratio (NLR) in CVR stratification for patients with HS. A cross-sectional study was performed to assess the role of SII and NLR in CVR stratification in patients with moderate to severe HS who were candidates for biologic therapy. SII, NLR, carotid intima-media thickness, and other clinical and biochemical CVR factors were assessed before the start of the treatment. Fifty patients were included. The male:female ratio was 3:2, and the mean International Hidradenitis Suppurativa Severity Score System score was 21.6. After multivariate analysis, SII correlated with higher values of systolic blood pressure, metabolic syndrome, and higher risk of insulin resistance (p < 0.05). NLR was associated with insulin resistance (p < 0.05). These associations were independent of age, sex, body mass index, severity of the disease, and tobacco consumption. The implementation of SII and NLR in daily practice may be of benefit for identifying patients with HS at higher risk of high blood pressure, insulin resistance, or metabolic syndrome. Since these indexes are simple to calculate, they could be used as a screening tool in HS-specific units., (© 2022 Japanese Dermatological Association.)

Background: Early detection of melanoma is one of the main diagnostic goals of dermatologists worldwide, due to the increasing incidence of the disease in our environment. However, the irruption of the SARS-CoV-2 pandemic has posed a challenge to global healthcare, forcing systems to focus their resources on the fight against COVID-19. Methods: Retrospective cohort study. The exposed cohort were patients diagnosed with melanoma in the year after the general confinement in Spain (15 March 2020) and the unexposed cohort were patients with melanoma diagnosed in the previous year. Results: 130 patients were included. No differences were observed between demographic characteristics in both cohorts. The mean Breslow of melanoma before the onset of the pandemic was 1.08, increasing to 2.65 in the year after the onset of the pandemic (p < 0.001). On the other hand, the percentage of melanomas in situ decreased from 38.96% to 16.98% in the year after the declaration of the state of alarm in Spain. Conclusions: The SARS-CoV-2 outbreak has led to a reduction in the early diagnosis of melanoma, with an increase in invasive melanomas with poor prognosis histological factors. This could lead to an increase in melanoma-related mortality in the coming years in our environment.

Background: Photodynamic therapy (PDT) has become one of the most effective therapies for the treatment of actinic keratosis, allowing the removal of more than one lesion in a single session. However, the pain sustained by the patient during treatment and local skin reactions can limit its use., Objectives: To determine the efficacy and safety of combined PDT (daylight PDT followed by conventional PDT) vs conventional PDT 12 weeks after treatment., Methods: The study was performed as a randomized, single-center, non-inferiority clinical trial with two parallel groups. A total of 51 patients with grade I and II AKs on the scalp or face were randomized. Twenty-five patients received one session of combined PDT (combPDT), and 26 patients received one session of conventional PDT (cPDT). The primary endpoint was the reduction of AKs, 12 weeks after treatment. The secondary endpoint was the reduction in pain and local skin reaction., Results: The reduction rate of grade I and II AKs was similar in combPDT and cPDT, showing no statistically significant differences between both groups, 76.67% vs 86.63% [P = .094] and 80.48% vs 83.08% [P = .679], respectively. However, pain was significantly lower in the combPDT group (2.56 vs 5, P < .01), as were local skin reactions., Conclusions: CombPDT has proven to be as effective as cPDT for the treatment of grade I and II AKs located on the scalp and face. Furthermore, combPDT has been shown to be considerably more tolerable than cPDT, causing only mild local skin reactions., (© 2021 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Introduction: Coronavirus disease 2019 (COVID-19) has increased the frequency of handwashing. There is scarce evidence regarding the impact of different hand hygiene procedures on skin barrier function in clinical practice., Objective: To compare the impact on skin barrier function of different hand hygiene measures in healthcare workers in daily practice., Methods: A randomized controlled clinical trial was conducted. Participants were randomized to sanitize their hands with water and soap, alcohol-based hand sanitizers (ABHSs), or disinfectant wipes during their 8-hour working shift. Epidermal barrier functional parameters, such as transepidermal water loss (TEWL), and the microbial load were assessed before and immediately after the working day. Tolerance and acceptability of each product were recorded after work., Results: Sixty-two participants were included and 20, 21, and 21 were randomized to use water and soap, ABHS, and disinfectant wipes, respectively. After the 8-hour shift, TEWL increase was higher with disinfectant wipes than with soaps or ABHS (+5.45 vs +3.87 vs -1.46 g h -1  m -2 , respectively; P = .023). Bacteria and fungi colony-forming unit (CFU) count reductions were lower for the water and soap group than for ABHS and disinfectant wipes. Disinfectant wipes were considered more difficult to use (P = .013) compared with water and soap and ABHS., Conclusion: Daily hand hygiene with ABHS showed the lowest rates of skin barrier disruption and the highest reduction of CFU., (© 2021 John Wiley & Sons A/S.

Adalimumab is currently the only biological medicine approved by the FDA for the treatment of hidradenitis suppurativa (HS). The breakout of biosimilar drugs made them more accessible due to their impact on pharmacoeconomics. However, packaging, formulation, or excipients are unique characteristics of each drug. In that way, switching from adalimumab originator to biosimilar and between biosimilars could have implications in the clinical practice. The objective of this study is to describe our clinical experience in switching from adalimumab originator to biosimilar and switching back again. A single-center retrospective cohort study was conducted that included seventeen patients with HS treated with adalimumab originator in the maintenance phase, and that achieved Hidradenitis Suppurativa Clinical Response (HiSCR), who were switched to adalimumab biosimilar for no medical reasons. The reason for the change was to improve pharmacoeconomic efficiency, following our hospital policies on biologics. Median duration with adalimumab originator treatment before switching was 48 weeks. After switching, 41.2% of patients maintained HiSCR response without additional issues, while 58.8% (10/17) reported problems after the change. Switching from adalimumab originator to biosimilar in well-controlled patients could imply problems in efficacy and adherence. Switching back to adalimumab originator appears to solve most of the problems, but some patients can lose confidence in the drug and discontinue it. It would be worthwhile to evaluate the benefit-risk ratio individually when switching an HS patient to adalimumab biosimilar.

Skin is damaged in atopic dermatitis (AD) patients. Age is also believed to have a negative effect on epidermal barrier function. The aim of this study was to investigate skin barrier function changes with age in AD patients. A cross-sectional study was conducted including 162 participants, 81 AD patients and 81 healthy volunteers. Skin barrier function parameters, such as transepidermal water loss (TEWL), erythema, temperature, stratum corneum hydration (SCH), pH, and elasticity, were evaluated. Healthy volunteers were evaluated on the volar forearm. AD patients were measured on two regions: on an eczematous lesion on the volar forearm and on a non-involved area 5 cm from the affected area. TEWL was lower on healthy skin than uninvolved AD skin (9.98 vs. 25.51 g·m -2 ·h -1 , p < 0.001) and AD eczematous lesions (9.98 vs. 28.38 g·m -2 ·h -1 , p < 0.001). SCH was lower on AD eczematous lesions than uninvolved AD skin (24.23 vs. 39.36 AU, p < 0.001) and healthy skin (24.23 vs. 44.36 AU, p < 0.001). Elasticity was lower on AD eczematous lesions than uninvolved AD skin (0.69 vs. 0.74, p = 0.038) and healthy skin (0.69 vs. 0.77, p = 0.014). A negative correlation was found between age and elasticity in all the population (r = -0.383, p < 0.001). This correlation was stronger in AD patients (r = -0.494, p < 0.001) than in controls (r = -0.266, p = 0.092). After conducting a linear regression model in AD patients adjusted by age, sex, and SCORing Atopic Dermatitis (SCORAD), it was found that elasticity was impaired by an increasing age (β = -0.004, p < 0.001) and a higher SCORAD (β = -0.003, p < 0.001). The skin barrier function is impaired by age and AD, reflected mainly in poor elasticity values in older AD patients.

Hidradenitis suppurativa (HS) is an inflammatory chronic disease with difficult management. In some scenarios, intralesional (IL) treatments could be useful. However, the scientific evidence available is limited and heterogeneous. We aimed to synthesize the available scientific evidence on IL treatments in HS. We conducted a systematic review in July 2021. The clinical databases reviewed included MEDLINE and Embase. All types of epidemiological studies and case series with at least 10 patients were included; reviews, guidelines, protocols, conference abstracts, case series with less than 10 patients, and case reports were excluded. Fifteen articles representing 599 patients and 1,032 lesions were included for review. Corticosteroid injections were the most reported treatment. They showed effectiveness for the treatment of acute inflammatory lesions and fistulas in terms of reduction of lesion counts, symptoms, and signs of inflammation and were safe in general terms. Light-based therapies were the other main treatment group, including photodynamic therapy and 1,064-nm diode laser. They were also effective, but more local and systemic adverse events were reported. Other treatments included botulinum toxin type B and punch-trocar-assisted cryoinsufflation (cryopunch). They were effective and safe, although were reported anecdotally. The main limitation of the systematic review was the general quality of the articles included. In conclusion, IL treatments such as corticosteroid injections and light-based therapies seem to be effective and safe for both acute inflammatory lesions and fistulas, although more prospective studies, with higher sample sizes and with standardized outcomes are needed to provide more scientific evidence on the subject., (© 2022 S.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a global pandemic that has spread all over the word. To avoid the virus transmission, healthcare workers must wear adequate personal protective equipment (PPE). PPE is associated with several side events, including skin reactions. The objective of this study was to summarize the prevalence, type and risk factors for cutaneous adverse events related to PPE and prevention measures to avoid them. A systematic review and meta-analysis was conducted using MEDLINE, Scopus and EMBASE databases from conception to 21 January 2021. All types of epidemiological studies regarding skin adverse events related to PPE were included. The literature search identified 1007 references, 35 of them met the eligible criteria and were included for analysis, representing 31 453 participants. The media of skin side events related to PPE was 75.13%. The rate of cutaneous adverse events related to mask was 57.71%, and those associated with gloves and hand hygiene products was 49.16%. Most common skin adverse events were contact dermatitis, acne and itching. The most damaged anatomical regions were the nasal bridge, the cheeks and the hands. The duration of PPE wearing was the most common risk factor. Frequent handwashing, gloves and masks were the agents most frequently related to skin reactions. N95 respirators were the most harmful mask type for the skin. Hydrocolloid use prevented from developing skin adverse events related to masks. In conclusion, the rate of cutaneous adverse events related to PPE use is high. A longer duration of PPE wearing was the most common risk factor. Using hydrocolloid could prevent from skin injuries related to mask use., (© 2021 The Authors.

Background: Tetracyclines and clindamycin plus rifampicin combination therapy are both considered first-line therapy in current hidradenitis suppurativa guidelines. However, evidence for their efficacy is drawn from small studies, often without validated outcomes., Objective: To assess the 12-week efficacy of oral tetracyclines and a combination of clindamycin and rifampicin., Methods: A prospective, international cohort study performed between October 2018 and August 2019., Results: In total, 63.6% of the included 283 patients received oral tetracyclines, and 36.4% were treated with clindamycin and rifampicin. Both groups showed a significant decrease in International Hidradenitis Suppurativa Severity Score System from baseline (both P < .001). The Hidradenitis Suppurativa Clinical Response (HiSCR) was achieved in 40.1% and 48.2% of patients, respectively (P = .26). Patient characteristics or disease severity were not associated with the attainment of HiSCR or the minimal clinically important differences for the Dermatology Life Quality Index and pain., Limitations: Cohort study. Respectively, 23.9% and 19.4% of patients had to be excluded from the HiSCR analysis for the tetracycline and combination therapy group because of a low abscess and nodule count at baseline., Conclusion: This study shows significant efficacy of both tetracycline treatment and clindamycin and rifampicin combination therapy after 12 weeks in patients with hidradenitis suppurativa. No significant differences in efficacy were observed between the 2 treatments, regardless of disease severity., Competing Interests: Conflicts of interest Dr Tzellos has reported relationships with AbbVie, UCB, and Sanofi Genzyme.

There is a need to establish the role of antiandrogens as an alternative or concomitant therapy for hidradenitis suppurativa (HS). Thus, the objectives of this study are (1) to assess the effectiveness of oral contraceptive pills (OCPs) at week 12 in HS women, and (2) to describe the clinical profile of patients receiving oral contraceptive pills (OCPs). A prospective observational study was designed. This study included 100 participants, 50 women with HS who started OCPs for the first time at our HS Clinic and 50 participants without OCP treatment. The main outcome of interest was the percentage of reduction in total abscess and inflammatory nodule (AN) count at week 12. Thirty-three women received combined OCPs and 17 non-combined OCP. HS patients with OCPs treatment were younger (31.7 vs. 40.9 years, p < 0.001), thinner (28.62 vs. 33.35 kg/m 2 ), and have a higher number of areas affected (2.32 vs. 1.38, p = 0.02) than those without OCPs. After 12-weeks of treatment, it was observed that the percentage of AN reduction was higher in HS women receiving OCP than in patients without OCP (53.9% vs. 38.42%, p = 0.049). It was observed that OCP prescription (β = 3.79, p = 0.034) and concomitant therapy (β = 3.91, p = 0.037) were independently associated with a higher % AN when controlling for disease duration, concomitant therapy, and treatment with/without OCP (R 2 = 0.67). The factors potentially associated with the percentage AN reduction at week 12 in HS women treated with OCPs were disease duration (β = -1.327, p = 0.052), concomitant therapy (β = 11.04, p = 0.079), and HS worsening with the menstrual cycle (β = 10.55, p = 0.087). In conclusion, OCPs might be effective for improving AN count in women with HS. Women whose HS worsens in relation to the menstrual cycle and have a shorter disease may benefit more from the therapeutic effect of OCPs.

Hidradenitis suppurativa (HS) is a chronic, recurrent and debilitating inflammatory skin disease of the hair follicle that usually presents as painful, deep-seated inflamed lesions in the apocrine gland-bearing areas of the body. HS patients suffer from uncomfortable signs and symptoms, such as pain, pruritus, malodour and suppuration, which may impair patients' quality of life (QoL). Although HS patients frequently experience these signs and symptoms, they are only occasionally assessed by clinicians and, unexpectedly, the scientific evidence available is limited and heterogeneous. The aim of this study is to summarize the evidence regarding the impact of HS signs and symptoms on QoL to serve as a basis for future research and help clinicians to consider them in the daily care of HS patients. A systematic review and meta-analysis were conducted following PRISMA Guidelines. The following search algorithm was used: (hidradenitis or "acne inversa") and (pain or itch or odour or malodour or suppuration or oozing or drainage) and ("quality of life"). The literature search identified 836 references, 17 of them met the eligible criteria and were included for analysis, representing 4929 HS patients. Mean age of the participants was 36.28 years and there was a predominance of female sex among study participants. The BMI of the population was in the range of over-weight and about two out five patients were active smokers. Studies included patients with mild to moderate HS, with a mean disease duration of 13.69 years. The HS signs and symptoms assessed were pain, pruritus, malodour and suppuration. Overall, the higher intensity of a sign or symptom correlated with poorer general QoL or specific QoL dimensions including sexual distress, anxiety, depression and sleep. The most frequently employed tool to assess QoL was the Dermatology Life Quality Index (DLQI). DLQI was used in 52.9% of the studies (9/17) with a mean value of 10.70 (2.16 SD). The scores employed to assess signs and symptoms severity were subjective and varied between studies, being the numerical rating scale (NRS) for each of the most used symptoms. The mean NRS value for pain was 3.99 and the mean NRS for pruritus was 4.99. In conclusion, we have summarized, categorized and analyzed the scientific evidence regarding signs and symptoms in HS patients and their impairment in QoL. Their assessment should be thorough and included during routine evaluation of HS patients to motivate therapeutic modifications and increase patients' health.

Background and Objectives: Information about hospital admissions for skin diseases is restricted to studies describing admissions to single centers, to specific wards, or only for a few diagnoses, and there is no information about the outcomes between different wards. The aim of this research is to describe hospital admissions due to dermatological diseases., Patients and Methods: Cross-sectional study of hospital discharges at Spanish hospitals. Discharges were assumed to be the same as admissions., Results: 519,440 discharges (1.1 % of total discharges) were identified. Most admissions (60.1 %) were done from emergency departments. Only 7 % of cases were admitted to dermatology wards. The most prevalent group was cellulitis and acute lymphangitis. Median age was 57 years, and men were more common. The median length of hospital stay was four days; 40,823 (7.9 %) cases required readmission. There were 13,558 (2.6 %) hospital deaths. After adjusted analysis (by age, sex and group of diagnosis), the OR of readmission was 1.49 (95 % CI: 1.42-1.57) times higher and length of stay was 0.22 (95 % CI: 0.15-0.29) days longer in non-dermatology wards (P < 0.0001). From 2006-2016, admissions to dermatology wards decreased 38 %, while in non-dermatology wards they increased 8 %., Conclusions: A non-negligible number of patients require dermatological inpatient management. This is mainly provided by non-dermatologists. Some of our findings may indicate an improved overall care by dermatologists., (© 2021 Deutsche Dermatologische Gesellschaft (DDG).

Frontal fibrosing alopecia (FFA) is an emerging disease in Western countries. We present the cases of three sisters who were referred simultaneously to the Department of Dermatology, Hospital Universitario San Cecilio, Granada, Spain, in 2018. All patients suffered from at least partial frontotemporal hairline recession and eyebrow loss. Following trichoscopic examination, the three sisters were diagnosed with FFA. Only one of the sisters agreed to be treated; she was prescribed with topical clobetasol propionate solution and minoxidil and achieved disease control at the three-month follow-up. These patients represent a new case of familial FFA wherein three sisters as well as their mother were affected by FFA. A systematic review found a total of 24 cases of familial FFA, of which this report is the 25th. In the majority of families, only females were affected (88%) while in the remainder both males and females (8%) were affected; there was only one family where only males were affected (4%). The relationship between the affected individuals was predominately between sisters (56%) followed by mother and daughter (32%). The median age was 61 years old (range: 14-88 years) and the duration of the disease ranged between 3-360 months. Family groups of FFA are an infrequently described phenomenon with unknown prevalence., (© Copyright 2021, Sultan Qaboos University Medical Journal, All Rights Reserved.)

Hidradenitis suppurativa (HS) can cause considerable impact on several aspects of quality of life. Sexuality is a central aspect of quality of life. In recent years, there has been an increase in the number of articles on HS and sexuality. To achieve our aim of synthesizing the available scientific evidence on HS and sexual health, we conducted a systematic review in February 2020. The clinical databases used included Medline and Embase. All types of epidemiological articles were included; reviews, guidelines, protocols, conference abstracts and case report articles were excluded. Eleven studies were included for review, representing 42 729 patients with HS. The most common study design was cross-sectional with or without comparison group(s), conducted in an outpatient setting or through surveys. Prevalence of sexual dysfunction ranged between 51-62%, and in the case of erectile dysfunction, a specific kind of sexual dysfunction affecting penile erection, it ranged from between 52% and 60% of patients studied using validated questionnaires. Potential risk factors for sexual dysfunction among men and women were identified, mainly related to disease activity, symptoms and partners. Mood disorders like depression and anxiety appear to be associated with sexual dysfunction. Women were more affected by sexual distress. HS patients with sexual dysfunction had a decreased overall quality of life. With respect to treatment, surgery did not improve sexual function and there is no scientific evidence regarding medical treatments. Patients stated that they would like to treat their sexual problems with healthcare professionals. In conclusion, sexual and erectile dysfunction are common in HS patients, and negatively affect their quality of life. There are clinical factors potentially associated with this which should be identified and treated by dermatologists in the comprehensive care of HS patients. Prospective studies are needed to provide more scientific evidence on this unmet need., (© 2020 European Academy of Dermatology and Venereology.)

Background: Coronavirus disease 2019 has rapidly spread all over the world. Personal protective equipment (PPE) including masks and gloves is needed to avoid transmission. Adverse skin reactions associated with PPE have been described, but there is no information regarding objective measures to assess skin impairment related to PPE., Objective: The aim of the study was to evaluate the impact of using facial mask and nitrile gloves on epidermal barrier function and skin homeostasis., Methods: A cross-sectional study was designed. Thirty-four health care workers wearing nitrile gloves and a mask for 2 hours were included. Transepidermal water loss, stratum corneum hydration, erythema, and temperature were measured., Results: Transepidermal water loss (31.11 vs 14.24 g·m-2·h-1), temperature (33.29°C vs 32.57°C), and erythema were significantly greater at the area covered by gloves compared with the noncovered area. Transepidermal water loss (22.82 vs 13.69 g·m-2·h-1), temperature, and erythema (411.43 vs 335.52 arbitrary units) were significantly increased at the area covered by mask, whereas stratum corneum hydration was lower. Transepidermal water loss was greater at the area covered by a surgical mask than at a filtering respirator mask coded filtering facepiece 2 (27.09 vs 18.02 g·m-2·h-1, P = 0.034)., Conclusions: Skin homeostasis and epidermal barrier function may be impaired by gloves and mask use. High-quality PPE should be provided, and adequate skin prevention measures should be implemented to reduce epidermal barrier damage., Competing Interests: The authors have no funding or conflicts of interest to declare., (Copyright © 2021 American Contact Dermatitis Society.

Background: New integrative hidradenitis suppurativa (HS) lesion pattern phenotypes have been proposed, an inflammatory phenotype (IP) and a follicular phenotype (FP). They are characterized by different lesion patterns, symptoms, and risks of disease progression., Objectives: To evaluate whether lesion pattern phenotypes (1) have a different cardiovascular risk factor profile, and (2) are associated with a different therapeutic approach in the setting of an HS clinic., Methods: A retrospective cohort study was conducted on 233 patients with HS. They were classified according to lesion pattern phenotype criteria. Data regarding cardiovascular risk factors and treatment decisions were gathered., Results: One hundred and seventeen HS patients (50.21%) were classified as FP and 112 (48.07%) as IP. IP was associated with more severe disease and greater impairment of quality of life. Regardless of disease severity, patients with IP may have a higher cardiovascular risk, assessed according to higher C-reactive protein (CRP) levels (12.75 vs. 5.89, p = 0.059). The lesion pattern phenotype also influenced treatment decisions regardless of disease severity. Patients with IP were more likely to be treated with systemic corticosteroids and adalimumab, showing that lesion pattern phenotypes are associated with different therapeutic approaches., Conclusions: IP is associated with higher CRP values, suggesting a greater cardiovascular risk in these patients and also a different therapeutic approach. This information could help guide dermatologists in the management of HS patients and help to determine future treatment recommendations., (© 2021 S. Karger AG, Basel.)

Keloids are a difficult-to-treat disease characterized by an imbalance in mechanisms of tissue reparation. We present the case of a middle-aged woman with spontaneous keloids which histologically and clinically improved after UVA-1 phototherapy treatment. There are few reported cases of keloids treated with high doses of UVA-1 phototherapy. We used a low-dosage regimen with a good response in only one cycle, which could diminish the risk of skin cancer development.

The new coronavirus, severe acute respiratory syndrome coronavirus 2, is associated with a wide variety of cutaneous manifestations. Although new skin manifestations caused by COVID-19 are continuously being described, other cutaneous entities should also be considered in the differential diagnosis, including adverse cutaneous reactions to drugs used in the treatment of COVID-19 infections. The aim of this review is to provide dermatologists with an overview of the cutaneous adverse effects associated with the most frequently prescribed drugs in patients with COVID-19. The skin reactions of antimalarials (chloroquine and hydroxychloroquine), antivirals (lopinavir/ritonavir, ribavirin with or without interferon, oseltamivir, remdesivir, favipiravir, and darunavir), and treatments for complications (imatinib, tocilizumab, anakinra, immunoglobulins, corticosteroids, colchicine and low molecular weight heparins) are analyzed. Information regarding possible skin reactions, their frequency, management, and key points for differential diagnosis are presented., (Copyright © 2020 American Academy of Dermatology, Inc.

Little is known about the impact of hidradenitis suppurativa (HS) on patients' sexuality. The aim of this research is to investigate the impact of HS on several previously unexplored aspects of sexuality. In March 2018, we conducted a crowd-sourced cross-sectional online survey hosted by the Spanish association of patients with HS (ASENDHI) and available in Spanish. A panel of experts and patients from ASENDHI designed various questions in order to explore the extent to which HS influenced participants' sex lives. The final sample consisted of 386 participants, 79.27% (306/386) of which were women and 20.73% (80/306) of which were men. Seventy-seven point one percent (236/306) of women and 67.5% (54/80) of men were in stable relationships; the rest of the participants were single. Forty-seven point nine percent (185/386) admitted to feeling fear of rejection. Pain was the symptom that most interfered with sexual relations in women and suppuration in men. Forty-four point three percent (171/386) of the participants considered themselves to be less attractive than average. Considering the participants in a stable relationship, women described receiving more emotional support from their partners, while men received more help with lesion dressing in intimate areas. Seventy-one point four percent (207/290) of participants stated that HS negatively affected their relationship. Among single patients, women experienced greater fear of rejection and were less willing to meet new people because of HS. Ninety-four point three percent (66/70) of women and 80.8% (21/26) of men stated that HS had a negative influence on their chances of having a relationship or sexual relations. In conclusion, HS has a significant, unrecognized and misunderstood impact on sexuality which must be addressed.

Introduction: There are an increasing number of biologic drugs in the pipeline for treating hidradenitis suppurativa (HS). Clinical trials for these drugs usually share the same clinical selection criteria., Objectives: (a) To describe the clinical profile of HS patients receiving first-line biologic treatment in an HS clinic setting, (b) to assess how this population would meet clinical criteria to participate in a clinical trial, and (c) to assess treatment effectiveness at week 16 in eligible vs non-eligible patients., Methods: Prospective observational study. Patients were grouped according to their eligibility for clinical trials. The effectiveness of adalimumab was assessed by HiSCR, IHS4-category-change and a-50%-reduction on IHS4 at week 16., Results: Thirty-eight patients were included in the study: eight (21.05%) were eligible for clinical trials and 30 (78.95%) were not. The main reason for non-eligibility was not having an AN count ≥5. Both groups presented similar number of draining tunnels. Effectiveness at week 16 was lower in non-eligible than eligible patients when evaluated by HiSCR-response but similar if evaluated by the IHS4-category-change or the 50%-reduction in IHS4., Conclusion: In our population, the external validity of current eligibility criteria for clinical trials is low. Most patients receiving adalimumab in real-life setting would not be eligible for clinical trials., (© 2020 Wiley Periodicals LLC.)
