PurposeThe frequency of injuries sustained while playing on inflatable toys such as bouncy castles have rapidly increased. These supposedly safe structures are likely unsafe. The objective of this review was to investigate the risk that these attractions represent and the necessary measures to minimize risk of accidents.MethodsWe conducted a prospective study of 114 patients over a period of one year (2015 to 2016). Demographic data collected included: age, gender, anatomical location and side of involvement as well as supervision of the child whilst on the bouncy castle. The extracted data include mechanism of injury and risk factors, i.e. lack of supervision of the child, amounts of users jumping at the same time.ResultsThe injuries were slightly more frequent in male than female children; 2:1 up to six years of age. From the age of ten to 14 years the ration evened to 1:1, the higher incidence in female children was between the ages of six to eight years.The most common injuries were to the humerus, followed by the distal radius. Only 28% of the parents said they were supervising while the child was jumping.ConclusionInjuries associated with inflatable bouncers have increased over time. The main risk factors: were lack of effective adult supervision and the shared use by an excessive number of participants of different ages and weights.These considerations lead to the conclusion that there is a necessity to enhance child health surveillance and to consider limiting bouncer usage to children over the age of six years, to prevent and control injuries and to minimize their consequences.Level of EvidenceII - prospective study

Objetivo: El fibroqueratoma periungueal adquirido es un tumor fibroepitelial benigno, con escasa incidencia a nivel del pie. Es una tumoración cubierta de piel hiperpigmentada con hiperqueratosis en su porción distal, de consistencia firme e indurada, y tamaño variable, que oscila entre los 3 y los 15 mm. de diámetro. Material y métódos: Presentamos un varón de 6 años de edad, con una tumoración de 0,4 x 0,5 cm, dolorosa compatible con fibroqueratoma periungueal adquirido a nivel del hallux. Dada la edad del paciente, hay que realizar diagnóstico diferencial con tumor de Köenen. Resultados: Tras la resección quirúrgica según técnica de colgajo en bandera, el estudio histopatológico confirma la sospecha clínica. Conclusiones: El fibroqueratoma periungueal adquirido, es una entidad clínica e histológica bien definida y muy característica, cuyo diagnóstico puede realizarse con toda certeza y su tratamiento definitivo se realizará por medio de la escisión definitiva de la lesión.
