ABSTRACT
Nail changes are a common side effect of taxane chemotherapy, although onycholysis is quite a rare complication the correct management of which is poorly standardized. These case reports provide a description and analysis of onycholysis, a rare but noteworthy complication observed during taxane-based chemotherapy with concomitant cryotherapy in two patients with breast cancer. Despite prophylactic measures, both cases experienced nail complications during Paclitaxel treatment, underlining the complex nature of onycholysis during taxane therapy and highlighting the critical role of nail assessment and infection screening.

INTRODUCTION: Nail psoriasis is common in psoriasis vulgaris and even more prevalent in psoriatic arthritis. Dermatoscopy of the nail proves helpful in enhancing the visualization of psoriatic nail lesions. OBJECTIVE: This systematic review aimed to summarize the existing studies published in the literature that reported the various dermoscopic features of nail psoriasis. MATERIALS AND METHODS: A systematic search of two medical databases, PubMed and Scopus, was conducted in April 2023. In total, 11 records were included. The number of reported cases in the included studies was 723. RESULTS: The average age was 42.39 years. Sixty percent of patients were males, and 40% were females. Pitting constituted the most common onychoscopic feature indicating nail matrix involvement, followed by various other features such as leukonychia, nail plate thickening, transverse and longitudinal ridges, and different lunula abnormalities. The predominant onychoscopic feature indicating nail bed involvement was onycholysis, followed by splinter hemorrhages, oil drop sign, subungual hyperkeratosis, dilated capillaries, agminated capillary dots, erythematous border, and pustules. Vascular abnormalities observed in all locations were present in 52% of patients. CONCLUSIONS: The clinical signs of nail psoriasis are diverse, and for the majority, they are nonspecific. Nail dermoscopy is a noninvasive tool that enhances the visualization of the nail manifestations of psoriasis. It may facilitate the establishment of diagnostic criteria for this pathology without resorting to more invasive procedures, such as nail biopsy.

Introdução: A síndrome mão-pé é uma reação adversa experimentada por vários pacientes em tratamento para o câncer e fator preditor de morbidade e mortalidade. Objetivo: Avaliar as evidências científicas relacionadas à identificação, prevenção e tratamento da síndrome mão-pé induzida por agentes quimioterápicos, identificar os principais sinais e sintomas que possibilitam o reconhecimento da síndrome e, ainda, discutir a ocorrência de onicomicoses no contexto da síndrome mão-pé. Método: Trata-se de uma revisão sistemática na MEDLINE/PubMed, Biblioteca Virtual da Saúde e Scopus, incluindo literatura cinzenta e busca manual. Os 29 estudos incluídos na revisão foram analisados e classificados segundo a hierarquia dos níveis de evidência Grading of Recommendations Assessment, Development and Evaluations (GRADE) e a confiabilidade entre os examinadores (coeficiente Kappa) foi calculada. Resultados: Foram identificados estudos que demonstraram eficácia na prevenção da síndrome mão-pé com o uso da crioterapia e hidroterapia. Evidenciaram-se resultados satisfatórios com o uso do creme de ureia na prevenção e tratamento, e o uso de piridoxina não apresentou resultados conclusivos. Foram encontrados mecanismos para identificação da síndrome e para classificação dos agentes indutores. O grupo dos taxanos predominou entre os medicamentos indutores da síndrome mão-pé. Conclusão: Existem evidências consistentes, porém não contemplam todos os fármacos indutores da síndrome e não exploram outras manifestações relacionadas às onicólises e onicomicoses. O estudo apresentou resultados que poderão auxiliar os prescritores na identificação da síndrome mão-pé, além de alternativas para prevenção e tratamento. Contudo, vale destacar a necessidade de pesquisas futuras para elucidar a etiologia e protocolos de tratamento.
Introduction: Hand-foot syndrome is an adverse reaction experienced by many cancer patients and a predictor of morbidity and mortality. Objective:To evaluate the scientific evidence related to the identification, prevention and treatment of chemotherapeutic-induced hand-foot syndrome, to identify the main signs and symptoms that enable the recognition of the syndrome, and to discuss the occurrence of onychomycosis in the context of the hand-foot syndrome. Method: This is a systematic review at MEDLINE/PubMed, Virtual Health Library and Scopus, including gray literature and manual search. The 29 studies included in the review were analyzed and graded according to the hierarchy of evidence levels Grading of Recommendations Assessment, Development and Evaluations (GRADE) and reliability among examiners (Kappa coefficient) was calculated. Results:It were identified studies that demonstrated efficacy in preventing hand-foot syndrome using cryotherapy and hydrotherapy. Satisfactory results were evidenced with the use of urea cream for prevention and treatment, and the use of pyridoxine showed inconclusive results. Mechanisms for identification of the syndrome and classification of inducing agents were found. The taxane group predominated among hand-foot syndrome inducing drugs. Conclusion: There are consistent evidences but do not include all drugs inducing the syndrome and do not explore other manifestations related to onycholysis and onychomycosis. The study presented results that may help prescribers to identify hand-foot syndrome, as well as alternatives for prevention and treatment. However, it is worth highlighting the need for future studies to elucidate the etiology and treatment protocols.
Introducción: El síndrome de pies y manos es una reacción adversa experimentada por muchos pacientes con cáncer y un predictor de morbilidad y mortalidad. Objetivo: Evaluar la evidencia científica relacionada con la identificación, prevención y tratamiento del síndrome de pies y manos inducido por quimioterapia, identificar los principales signos y síntomas que permiten el reconocimiento del síndrome y analizar la aparición de onicomicosis en el contexto del síndrome mano-pie. Método:Esta es una revisión sistemática en MEDLINE/PubMed, Virtual Health Library y Scopus, que incluye literatura gris y búsqueda manual. Los 29 estudios incluidos en la revisión se analizaron y clasificaron de acuerdo con la jerarquía de los niveles de evidencia Grading of Recommendations Assessment, Development and Evaluations (GRADE). Resultados: Identificamos estudios que demostraron eficacia en la prevención del síndrome mano-pie usando crioterapia e hidroterapia.

Desde el siglo V a.C. Hipócrates ya describía las afectaciones ungueales, las cuales luego se relacionaban con enfermedades sistémicas o adquiridas. Los médicos de medicina del trabajo se deben preparar para detectar las afectaciones por factores externos. Sin embargo son pocos los casos publicados sobre patología ungueal de origen ocupacional. Nuestra revisión consiste en brindar conocimientos básicos sobre esta asignatura. Desde su definición, función y la descripción de su anatomía. La patología ungueal la clasificaremos según: a) anomalías de: la forma, de la adhesión, de la coloración, superficie, infección; b) según el mecanismo de acción que se producen o c) según el tipo de ocupación. Al adquirir estos conocimientos podremos establecer posteriores pautas de prevención eficaces (AU)
From the V century B.C. Hippocrates described the damages in the nails, which then were related to systemic diseases or acquired. As physicians we must prepare work to detect the effects caused by external factors. However, few published cases of occupational origin nail pathology. Our review is to provide basic knowledge on this subject. From its definition, function and description of the anatomy. The nail pathology classify as: a) anomalies: the way of accession, coloration, surface, infection, b) according to the mechanism of action that occur oc) by type of occupation. By acquiring this knowledge we can establish effective prevention guidelines later (AU)
