[Translated article] Glucagon-Like Peptide-1 Agonists for Treating Obesity in Patients With Immune-Mediated Skin Diseases / Agonistas del receptor de GLP-1 para el tratamiento de la obesidad en pacientes con dermatosis inmunomediadas

Psoriasis and hidradenitis suppurativa are often associated with obesity. Because chronic low-grade inflammation underlies these 2 diseases, they can progress to more severe forms in patients with obesity if weight-reduction measures are not taken. This review covers pharmacologic alternatives for treating obesity, with emphasis on the benefits associated with the novel use of glucagon-like peptide-1 (GLP-1) agonists that act on satiety receptors. These drugs have led to greater weight loss in clinical trials and real-world settings than orlistat, which until recently was the only drug approved for treating obesity in the European Union. Although experience with GLP-1 agonists in patients with obesity and inflammatory skin diseases is currently scarce, the promising results reported suggest they may offer a useful tool for managing obesity (AU)

La psoriasis (PsO) y la hidradenitis supurativa (HS) se asocian frecuentemente con la obesidad. La inflamación crónica de bajo grado subyace a estas condiciones, por lo que si no se adoptan medidas para reducir el peso del paciente con obesidad y PsO o HS, estas podrían evolucionar hacia formas más graves. Este trabajo revisa las opciones farmacológicas para tratar la obesidad, profundizando en los beneficios asociados al uso novedoso de agonistas del receptor de GLP-1 (arGLP-1), que actúan sobre los centros de la saciedad. Los resultados de ensayos y vida real demuestran que esta medicación consigue mayores pérdidas de peso que orlistat, hasta recientemente el único fármaco específico para la obesidad comercializado en la Unión Europea. Aunque la experiencia con arGLP-1 en pacientes con obesidad y dermatosis inflamatorias es escasa, los resultados son alentadores, por lo que podrían constituir una herramienta útil para el manejo de su obesidad (AU)

Risk of a Second Skin Cancer in a Cohort of Patients With Nonmelanoma Skin Cancer -Basal Cell Carcinoma or Squamous Cell Carcinoma-Treated With Mohs Micrographic Surgery: A National Prospective Cohort Study. / Riesgo de aparición de segundas neoplasias cutáneas en una cohorte de pacientes diagnosticados de carcinoma queratinocítico (carcinoma basocelular y carcinoma epidermoide) tratados con cirugía de Mohs. Estudio de cohortes prospectivo nacional.

OBJECTIVE: Patients with nonmelanoma skin cancer (NMSC)-ie, basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)-have an increased risk of developing a second skin cancer. The aim of this study was to describe the frequency, incidence per 1000 person-years, and predictors of a second skin cancer in a cohort of patients with NMSC treated with Mohs micrographic surgery (MMS). MATERIAL AND METHODS: Prospective study of a national cohort of patients with NMSC who underwent MMS at 22 Spanish hospitals between July 2013 and February 2020; case data were recorded in the REGESMOHS registry. The study variables included demographic characteristics, frequency and incidence per 1000 person-years of second skin cancers diagnosed during the study period, and risk factors identified using mixed-effects logistic regression. RESULTS: We analyzed data for 4768 patients who underwent MMS; 4397 (92%) had BCC and 371 (8%) had SCC. Mean follow-up was 2.4 years. Overall, 1201 patients (25%) developed a second skin cancer during follow-up; 1013 of the tumors were BCCs (21%), 154 were SCCs (3%), and 20 were melanomas (0.4%). The incidence was 107 per 1000 person-years (95% CI, 101-113) for any cancer, 90 per 1000 person-years (95% CI, 85-96) for BCC, 14 (95% CI, 12-16) per 1000 person-years for SCC, and 2 (95% CI, 1-3) per 1000 person-years for melanoma. More men than women developed a subsequent skin cancer (738 [61%] vs 463 [39%]). The main risk factors were a history of multiple tumors before diagnosis (relative risk [RR], 4.6; 95% CI, 2.9-7.1), immunosuppression (RR, 2.1; 95% CI, 1.4-3.1), and male sex (RR, 1.6; 95% CI, 1.4-1.9). CONCLUSION: Patients have an increased risk of developing a second tumor after MMS treatment of NMSC. Risk factors are a history of multiple tumors at diagnosis, immunosuppression, and male sex.

La utilidad de la nitroglicerina tópica al 0, 2% en la condrodermatitis nodular del hélix / The Usefulness of 0. 2% Topical Nitroglycerin for Chondrodermatitis Nodularis Helicis

INTRODUCCIÓN: La condrodermatitis nodular del hélix (CNH) es un proceso idiopático, degenerativo y doloroso que afecta a la piel y al cartílago del hélix o del antéhelix. Recientemente se ha descrito la utilidad de la nitroglicerina (NTG) tópica a 2% en el tratamiento de la CNH con buenos resultados, aunque con una tasa de efectos secundarios en el 17% de los casos. Es probable que a una concentración menor se pueda mantener el mismo efecto mejorando la tolerancia. Nuestra finalidad fue evaluar la efectividad y seguridad de la NTG tópica al 0,2% para el tratamiento de la CNH. MATERIAL Y MÉTODOS: Se llevó a cabo un estudio observacional retrospectivo entre los años 2012 y 2014 en 2 centros hospitalarios españoles. La efectividad se determinó a través de la evaluación clínica, realizada mediante seguimiento fotográfico, y de los síntomas de la lesión, medido mediante una escala numérica verbal. RESULTADOS: Veintinueve pacientes recibieron el tratamiento, de los cuales el 93% manifestaron una mejoría clínica con una duración media del tratamiento de 1,8 meses y un tiempo de seguimiento medio en los pacientes respondedores de 5,9 meses. La tolerancia fue buena en general en todos los casos. CONCLUSIÓN: La NTG tópica al 0,2% se plantea como una opción conservadora, efectiva y bien tolerada para el tratamiento de la condrodermatitis nodular del hélix que mejora tanto la apariencia clínica como la sintomatología en la mayoría de los pacientes

BACKGROUND AND OBJECTIVE: Chondrodermatitis nodularis helicis (CNH) is a painful idiopathic degenerative condition involving the skin and cartilage of the helix or antihelix of the ear. Topical nitroglycerin 2% is a relatively recent treatment option for CNH that has produced good results, although with adverse effects (17% of cases). The use of a lower concentration would probably achieve similar results with fewer adverse effects. The aim of this study was to evaluate the effectiveness and safety of topical nitroglycerin 0.2% in the treatment of CNH. MATERIAL AND METHODS: We performed a retrospective observational study of patients treated in 2 Spanish hospitals between 2012 and 2014. The effectiveness of treatment was determined by clinical photography and assessment of symptoms using a verbal numerical rating scale. RESULTS: Of the 29 patients treated, 93% showed clinical improvement. In the group of responders, mean treatment duration was 1.8 months and mean follow-up was 5.9 months. Overall tolerance was good in all cases. CONCLUSION: Topical nitroglycerin 0.2% is an effective and well-tolerated conservative treatment option that improves the appearance of lesions and provides symptomatic relief in the majority of patients with CNH

Folliculitis decalvans: a multicentre review of 82 patients.

BACKGROUND: Folliculitis decalvans (FD) is a rare neutrophilic scarring alopecia that represents a therapeutic challenge for dermatologists. OBJECTIVE: To describe the epidemiology, comorbidities, clinical presentation, diagnostic findings and therapeutic options in a large series of patients with FD. METHODS: This retrospective multicentre review includes patients diagnosed with FD based on clinical and histopathologic findings. The clinical severity was determined by the maximum diameter of the largest alopecic patch (slight: <2 cm, moderate: 2-4.99 cm, severe: 5 cm or more). Response to therapy was assessed as improvement, worsening or stabilization depending on the clinical symptoms (pruritus and trichodynia), inflammatory signs (erythema, pustules and crusts) and the extension of the alopecic patch. RESULTS: Overall, 82 patients (52 males and 30 females) with a mean age of 35 years were included. No significant comorbidities were present. A family history was present in three males. Severe FD was observed in 17 patients (21%). The independent factors associated with severe FD after multivariate analysis were: onset of FD before 25 years of age and presence of pustules. Oral antibiotics (tetracyclines and the combination of clindamycin and rifampicin) improved 90% and 100% of the patients, with a mean duration of response of 4.6 and 7.2 months respectively. CONCLUSIONS: The onset of FD before 25 years of age and the presence of pustules within the alopecic patch were associated with severe FD. Tetracyclines and the combination of clindamycin and rifampicin were the most useful treatments.

Carcinoma epidermoide cutáneo: definiendo la variante de alto riesgo / Cutaneous Squamous Cell Carcinoma: Defining the High-Risk Variant

El carcinoma epidermoide cutáneo, con una incidencia en la población general de aproximadamente un 10% a lo largo de la vida, es la segunda neoplasia más frecuente dentro del grupo del cáncer cutáneo no melanoma. La mayoría de los carcinomas epidermoides cutáneos muestran un comportamiento benigno y pueden ser completamente erradicados mediante cirugía y otros procedimientos dermatológicos. Sin embargo, existe un subgrupo de esta entidad que se asocia con una mayor capacidad de desarrollar metástasis nodal y, por tanto, con una elevada morbimortalidad. En el presente artículo se analizan los diferentes factores que definen al carcinoma epidermoide cutáneo de comportamiento agresivo. Proponemos un método de definición del carcinoma epidermoide de alto riesgo basado en el establecimiento de una serie de criterios mayores y menores. Este hecho supondrá una mejor evaluación pronóstica y un manejo personalizado de este grupo de enfermos, que puede resultar en un aumento de la supervivencia global (AU)

With a lifetime incidence of approximately 10% in the general population, cutaneous squamous cell carcinoma (CSCC) is the second most common type of non melanoma skin cancer. Most CSCCs are benign and can be completely eradicated by surgery or other dermatological procedures. There is, however, a subgroup associated with an increased likelihood of lymph node metastases and, therefore, with high morbidity and mortality. This article analyzes the various factors that define aggressive CSCC. We propose a method for defining high-risk SCC on the basis of a series of major and minor criteria. This method will allow better prognostic evaluation and enable personalized management of patients with high-risk SCC, possibly leading to improved overall survival (AU)

Parche biosintético de colágeno porcino como herramienta coadyuvante o definitiva en el cierre de defectos del cuero cabelludo sin periostio / Biosynthetic Porcine Collagen Dressings as an Adjunct or Definitive Tool for the Closure of Scalp Defects Without Periosteum

Introducción: Los carcinomas cutáneos agresivos que aparecen en el cuero cabelludo se desarrollan habitualmente en pacientes de edad avanzada que presentan múltiples comorbilidades. La exéresis completa de estos tumores incluye en muchos casos el periostio, lo que conlleva que la reconstrucción de este tipo de defectos se convierta en un reto. Objetivo: Se evalúa la utilidad de un parche de colágeno porcino tipo I como tratamiento coadyuvante o definitivo en el cierre quirúrgico de este tipo de defectos cutáneos. Material y métodos: Se realizó un estudio prospectivo en el que se incluyeron aquellos pacientes que presentaron defectos de más de 5 cm en el cuero cabelludo, en los que el periostio tuvo que ser extirpado para alcanzar márgenes libres de enfermedad entre enero de 2009 y noviembre de 2011. Resultados: La tumoración más prevalente fue el carcinoma epidermoide cutáneo recurrente. El defecto posquirúrgico osciló entre 5 y 7cm de diámetro. En el grupo de casos en los que se colocó un injerto posparche (n=4), en el 100% de los casos el tejido prendió completamente. En el caso de aquellos pacientes en los que el parche fue el recurso definitivo (n=6) el tejido de granulación generado por el material biosintético de colágeno porcino ocupó el defecto quirúrgico, dejándolo completamente restituido en aproximadamente 3,5 meses. Conclusiones: El parche de colágeno porcino tipo i es una herramienta sencilla, barata y eficaz en el tratamiento coadyuvante o definitivo del cierre de defectos quirúrgicos del cuero cabelludo de más de 5cm que carecen de periostio (AU)

Background: Aggressive carcinomas of the scalp usually occur in elderly patients with multiple comorbidities. Complete excision of this type of tumor often involves the removal of periosteum, and the resulting defects can be difficult to reconstruct. Objective: To evaluate the usefulness of porcine type I collagen dressings as adjunct or definitive treatment in the surgical closure of scalp defects without periosteum. Materials and methods: We performed a prospective study between January 2009 and November 2011 of patients with scalp defects larger than 5 cm resulting from surgery that required the removal of periosteum to obtain tumor-free margins. Results: The most prevalent type of tumor was recurrent cutaneous squamous cell carcinoma. The surgical defects ranged in diameter from 5 to 7 cm. In 100% of the patients who received a graft after dressing removal (n = 4), the graft took well. In the patients in whom the biosynthetic dressing was definitive (n = 6), granulation tissue filled the defect and complete closure was achieved in approximately 3.5 months. Conclusions: The use of porcine type I collagen dressings as an adjunct or definitive tool for the closure of surgical defects on the scalp measuring more than 5 cm in which periosteum has been removed proved to be simple, inexpensive, and effective (AU)
