Background: There are severaltherapeutic 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. Yes 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 aracterísticas del HI en la práctica clínica, incluyendo las terapias utilizadas, así como com parar 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 espanoles ˜ 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 tamano˜ 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.

Subcutaneous fat necrosis of the newborn (SCFN) is a rare, self-limited disorder of the panniculus which appears in the first few weeks of life. SCFN generally follows an uncomplicated course. However, there are important complications for which the patient must be regularly monitored, including thrombocytopenia, hypoglycemia, hypertriglyceridemia, and most importantly, hypercalcemia. We report five infants with SCFN. All children were born at term. The onset of lesions was between 1 day and 20 days after birth. The back was the most frequent location. Birth hypoxia was the most frequent risk factor. Complications included hypercalcemia, hypoglycemia, and metastatic calcifications (disseminated subcutaneous calcifications, nephrocalcinosis, and myocardial calcifications). This study provides the first case of SCFN in the context of hypoxic encephalopathy and refractory septic shock that required extracorporeal membrane oxygenation (ECMO).

[Background]: Previous reports on the prevalence of autosomal recessive congenital ichthyosis (ARCI) were based on single source data, such as lists of members in a patient association. These sources are likely to be incomplete. [Objectives]: We sought to describe the prevalence of ARCI. [Methods]: We obtained data from 3 incomplete sources (dermatology departments, a genetic testing laboratory, and the Spanish ichthyosis association) and combined them using the capture-recapture method. [Results]: We identified 144 living patients with ARCI. Of these, 62.5% had classic lamellar ichthyosis and 30.6% had congenital ichthyosiform erythroderma. The age distribution included fewer elderly patients than expected. The prevalence of ARCI in patients younger than 10 years, the best estimate as less subject to bias, was 16.2 cases per million inhabitants (95% confidence interval 13.3-23.0). According to the capture-recapture model, 71% of the patients were not being followed up in reference units, 92% did not have a genetic diagnosis, and 78% were not members of the ichthyosis association. [Limitations]: The prevalence of ARCI in Spain and findings related to the Spanish health care system might not be generalizable to other countries. [Conclusions]: The prevalence of ARCI is higher than previously reported. Many patients are not being followed up in reference units, do not have a genetic diagnosis, and are not members of a patient association, indicating room for improvement in their care. Data suggesting a reduced number of older patients might imply a shorter life expectancy and this requires further study.
