Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
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. 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. 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. La tumoración más prevalente fue el carcinoma epidermoide cutáneo recurrente. El defecto posquirúrgico osciló entre 5 y 7 cm 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. 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 5 cm que carecen de periostio. 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. To evaluate the usefulness of porcine type I collagen dressings as adjunct or definitive treatment in the surgical closure of scalp defects without periosteum. 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. 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. 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.
