ABSTRACT
The nail system forms a complex anatomical unit fundamental in humans, susceptible to numerous alterations due to both systemic and local pathological processes. The study of nail pathology is a subject of special interest, however, in the clinical setting, it is still difficult to analyse parameters such as specific area of extension, anatomy involved or percentage of involvement, making it difficult to carry out an objective assessment and establish effective treatment guidelines, having to resort, on numerous occasions, to histopathological examination. In this sense, measurement indices are positioned as a measurement tool that would allow these factors to be assessed in a numerical, reproducible and simple way. The aim of this study was to identify measurement tools for the different nail pathologies described in the literature. A peer-review of the literature was conducted in four databases according to Critical Appraisal Skills Programme España (CASPe) criteria. The findings described the existence of 12 nail pathology measurement tools. Conclusions finally pointed out the Nail Psoriasis Severity Index or NAPSI index as the most widely used method to asses the severity of nail psoriasis, despite reports of subsequent modifications. For onychomycosis, the Scoring Clinical Index for Onychomycosis or SCIO index appeared to be the most useful objective method in clinical practice. For chronic paronychia, the Chronic Paronychia Index standed out as a good alternative to previous assessment options.
RESUMEN
El sistema ungueal conforma una compleja unidad anatómica fundamental en el ser humano, susceptible de sufrir numerosas alteraciones debido a procesos patológicos, tanto sistémicos como locales. El estudio de la patología ungueal es un tema de especial interés, sin embargo, en el ámbito clínico todavía resulta complicado analizar parámetros como área concreta de extensión, anatomía comprometida o porcentaje de afectación, dificultando poder realizar una valoración objetiva y establecer pautas efectivas de tratamiento, debiendo recurrir, en numerosas ocasiones, al examen histopatológico. En este sentido, los índices de medición se posicionan como una herramienta que permitiría valorar estos factores de forma numérica, reproducible y simple. El objetivo de este estudio fue identificar las herramientas de medición de las diferentes patologías ungueales descritas en la literatura. Se realizó una revisión de la literatura por pares en cuatro bases de datos atendiendo a criterios del Critical Appraisal Skills Programme España (CASPe). Los hallazgos describieron la existencia de 12 herramientas de medición de patología ungueal. Las conclusiones señalaron, finalmente, el Nail Psoriasis Severity Index o índice NAPSI como método más utilizado para valorar la severidad de la psoriasis ungueal, pese a los reportes obtenidos en sus modificaciones posteriores. En cuanto a la onicomicosis, el Scoring Clinical Index for Onychomycosis o índice SCIO resultó ser el método objetivo más útil en la práctica clínica. Para la paroniquia crónica, el Índice de paroniquia crónica se distinguió como una buena alternativa a las opciones de valoración previas.
