[Translated article] Clinical and Epidemiological Characteristics of Patients Being Treated for Scabies in Spain: Opportunities for Improvement - A Multicenter Cross-Sectional CLINI-AEDV Study.

BACKGROUND: Several studies support the hypothesis that scabies is on the rise in Spain. There are also concerns about the possible development of resistance to treatment and an increase in atypical presentations. The aims of this study were to describe the demographic and clinical characteristics of patients with scabies seen by dermatologists in Spain, to identify the possible emergence of atypical forms of scabies, and to explore the frequency of treatment failures and associated risk factors. METHODS: We conducted an observational, cross-sectional, multicenter study of data collected prospectively in April and May 2023 using the CLINI-AEDVp platform created by the Spanish Academy of Dermatology and Venereology (AEDV). RESULTS: Participating dermatologists from 31 hospitals in 15 of Spain's autonomous communities recorded 186 cases of active scabies (51% in women) during the study period. A diagnostic certainty level of A, B or C as per the International Alliance for the Control of Scabies Consensus Criteria was required for diagnosis. Overall, 92% of patients had clinical features of classic scabies and 66% had already been treated with a scabicide for the current episode. Of the treated patients, only 36% had received and completed adequate treatment (including the simultaneous treatment of all household members) and 50% had not received clear written recommendations. CONCLUSIONS: In a high proportion of scabies cases, the patient has already received treatment. In those cases, we observe several remediable shortcomings that could explain why some of these treatments fail. Remedying these deficiencies should lead to better control of scabies and an improved assessment of the actual effectiveness of currently available scabicides.

A diagnostic certainty level of A, B or C as per the International Alliance for the Control of Scabies Consensus Criteria was required for diagnosis. Overall, 92% of patients had typical scabies and 66% had already been treated with a scabicide for the current episode. Of the treated patients, only 36% had received and completed adequate treatment (including the simultaneous treatment of all household members) and 50% had not received clear written recommendations. CONCLUSIONS: In a high proportion of the cases of scabies studied, the patient had already received treatment.

Cutaneous reactions after SARS-CoV-2 vaccination: a cross-sectional Spanish nationwide study of 405 cases.

BACKGROUND: Cutaneous reactions after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines are poorly characterized. OBJECTIVE: To describe and classify cutaneous reactions after SARS-CoV-2 vaccination. METHODS: A nationwide Spanish cross-sectional study was conducted. We included patients with cutaneous reactions within 21 days of any dose of the approved vaccines at the time of the study. After a face-to-face visit with a dermatologist, information on cutaneous reactions was collected via an online professional survey and clinical photographs were sent by email. Investigators searched for consensus on clinical patterns and classification. RESULTS: From 16 February to 15 May 2021, we collected 405 reactions after vaccination with the BNT162b2 (Pfizer-BioNTech; 40·2%), mRNA-1273 (Moderna; 36·3%) and AZD1222 (AstraZeneca; 23·5%) vaccines. Mean patient age was 50·7 years and 80·2% were female. Cutaneous reactions were classified as injection site ('COVID arm', 32·1%), urticaria (14·6%), morbilliform (8·9%), papulovesicular (6·4%), pityriasis rosea-like (4·9%) and purpuric (4%) reactions. Varicella zoster and herpes simplex virus reactivations accounted for 13·8% of reactions. The COVID arm was almost exclusive to women (95·4%). The most reported reactions in each vaccine group were COVID arm (mRNA-1273, Moderna, 61·9%), varicella zoster virus reactivation (BNT162b2, Pfizer-BioNTech, 17·2%) and urticaria (AZD1222, AstraZeneca, 21·1%). Most reactions to the mRNA-1273 (Moderna) vaccine were described in women (90·5%). Eighty reactions (21%) were classified as severe/very severe and 81% required treatment. CONCLUSIONS: Cutaneous reactions after SARS-CoV-2 vaccination are heterogeneous. Most are mild-to-moderate and self-limiting, although severe/very severe reactions are reported. Knowledge of these reactions during mass vaccination may help healthcare professionals and reassure patients.

Severe hidradenitis suppurativa complicated by renal AA amyloidosis.

Hidradenitis suppurativa (HS) is a chronic, recurrent inflammatory disease affecting the skin folds. Multiple therapeutic options have been proposed for severe cases, but persistent responses are rarely seen. Important complications of HS are uncommon, and usually seen only in severe and unresponsive disease. Amyloid A (AA) amyloidosis is secondary to inflammatory chronic diseases, and is an uncommon complication of dermatological diseases. Only a few cases related with HS have been reported. We report the case of a 37-year-old patient who developed AA amyloidosis secondary to severe HS.

Estudio retrospectivo de pilomatricomas: 261 tumores en 239 pacientes / Retrospective Study of Pilomatricoma: 261 Tumors in 239 Patients

INTRODUCCIÓN Y OBJETIVOS: El pilomatricoma es la segunda neoformación cutánea más frecuente en la infancia y la juventud, con un amplio diagnóstico diferencial. El objetivo principal del estudio fue determinar la incidencia de pilomatricomas en nuestro hospital y sus características en relación con: edad, sexo, localización, síntomas, traumatismo previo, diagnóstico clínico, enfermedades asociadas, casos múltiples, características ecográficas, tratamiento quirúrgico y técnica anestésica y complicaciones posteriores. MATERIAL Y MÉTODO: Se recogieron de forma retrospectiva los pilomatricomas extirpados quirúrgicamente en nuestro hospital de enero de 2004 a diciembre de 2012 a partir de la base de datos de anatomía patológica. RESULTADOS: Se estudiaron 261 pilomatricomas en 239 pacientes, 120 eran mujeres y 119 varones de edades comprendidas entre 1 y 83 años, con una media de 26,4 años. La forma de presentación más frecuente fue como un nódulo firme, subcutáneo, asintomático en el 82% de los casos. La localización más frecuente fue la cabeza y el cuello (49,81%). El diagnóstico clínico preoperatorio fue acertado en el 54,4%. Cincuenta y nueve pacientes tenían otras enfermedades y 7 recordaban traumatismo previo en la zona. Se registraron 17 casos múltiples, uno familiar, y 2 en pacientes con enfermedad de Steinert. En 57 lesiones se realizó ecografía de partes blandas, con imágenes compatibles con pilomatricoma en 48. Ciento ochenta y cinco pilomatricomas se extirparon con anestesia local y 76 con anestesia local y general. Como complicaciones posquirúrgicas hubo un caso de cicatriz hipertrófica y otro de dehiscencia. CONCLUSIONES: El nuestro es el estudio retrospectivo que recoge el mayor número de casos en nuestro país y uno de los que comunica mayor incidencia de casos. Además, se estudian variables no recogidas en otras series

BACKGROUND AND OBJECTIVES: Pilomatricoma is the second most common skin tumor in childhood and youth and it has a broad differential diagnosis. The main objective of the present study was to determine the incidence of pilomatricomas in our hospital and to analyze the following variables: patient age and sex, tumor site, symptoms, previous trauma, clinical diagnosis, associated diseases, number of cases of multiple tumors, ultrasound findings, anesthetic and surgical techniques, and postoperative complications. MATERIAL AND METHOD: This was a retrospective study of the pilomatricomas surgically excised between January 2004 and December 2012 and registered in the database of the pathology department of our hospital. RESULTS: We found 261 pilomatricomas in 239 patients (120 female and 119 male) between 1 and 83 years of age (mean age, 26.4 years). The most common presentation was as a firm subcutaneous nodule, which was asymptomatic in 82% of cases. Tumors most commonly affected the head and neck (49.81%). Preoperative diagnosis was correct in 54.4% of cases, concomitant diseases were present in 59 cases, and 7 patients reported a history of trauma in the area of the tumor. There were 17 cases of multiple tumors, 1 case in a patient with familial disease and 2 in patients with Steinert disease. Soft-tissue ultrasound was performed on 57 lesions; images were compatible with pilomatricoma in 48 cases. Tumor excision was performed under local anesthesia in 185 cases and under local and general anesthesia in 76. The postoperative complications were hypertrophic scarring and wound dehiscence (1 case each). CONCLUSIONS: This was a retrospective study with the largest series recorded in Spain and with one of the highest incidences. In addition, we report on variables not described in other studies

Neonatos con necrosis cutánea por extravasación de gluconato cálcico / Neonates with skin necrosis due to extravasation of calcium gluconate

Las lesiones cutáneas por extravasación se producen por la salida o introducción directa de fármacos o líquidos al tejido celular subcutáneo en el transcurso de un tratamiento intravenoso. Los fármacos que con mayor frecuencia producen daño por extravasación son las soluciones hiperosmolares, los agentes vasopresores y los quimioterápicos. El gluconato cálcico es un ácido débil que se comporta como una solución hipertónica. Los neonatos, los ancianos y los pacientes ingresados en unidades de cuidados intensivos son la población que presenta este tipo de complicación con mayor frecuencia y gravedad, debido a su mala perfusión y delgadez de la piel y a la incapacidad para localizar el dolor. Los casos descritos en la bibliografía de necrosis cutánea por gluconato cálcico en neonatos son excepcionales. No hay una única forma de tratamiento de este tipo de patología. Se han empleado pautas conservadoras o tratamientos agresivos, con escisión amplia de los tejidos y cierre mediante injerto. Presentamos los casos de 2 recién nacidos con necrosis cutánea secundaria a la extravasación de gluconato cálcico, sin infección asociada, que evolucionaron favorablemente con tratamiento conservador, consistente en el empleo de apósitos de colágeno de origen porcino. Según nuestra experiencia, ésta podría ser una alternativa terapéutica útil en pacientes con esta infrecuente patología (AU)

Cutaneous injury due to extravasation is produced by leakage or direct introduction of drugs or fluids into the subcutaneous tissue during intravenous therapy. Hyperosmolar solutions, vasopressor agents and chemotherapy are the most frequently agents related to extravasation injury. Calcium gluconate is a weak acid that acts as a hypertonic solution. Infants, elderly patients and intensive care unit patients are prone to this type of complication and more serious effects can be observed in this population because of poor skin perfusion, thinning of cutaneous tissue and the inability to locate the pain. In the literature cases described of skin necrosis by calcium gluconate in neonates are exceptional. There is not standard treatment established for this pathology. Both conservative or aggressive management like wide excision of tissue and grafting has been used to treatment of this complication. We report two cases of neonatal skin necrosis secondary due to extravasation of calcium gluconate in which conservative treatment with dressings porcine collagen was successful. In our experience, this could be a useful therapeutic alternative in patients with this rare disease (AU)
