ONYCHOLYSIS AS A COMPLICATION OF TAXANE-BASED CHEMOTHERAPY WITH CONCOMITANT CRYOTHERAPY IN BREAST CANCER PATIENTS: TWO CASE REPORTS.

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.

Two case studies of the treatment of simple onycholysis with disappearing nail bed caused by trauma by combined pharmacological, orthonyxia and taping methods.

BACKGROUND: Simple onycholysis is a common complaint after trauma and consists in separation of the nail plate from the nail bed. If untreated, prolonged onycholysis may cause a disappearing nail bed (DNB) that leads to the shortening or narrowing of the nail plate. OBJECTIVES: This study is aimed at discussing possible treatment of chronic simple onycholysis with DNB by combined conservative methods. METHODS: Simple onycholysis and DNB treatment consists of Onygen® cream application, nail bed massages, bracing procedures and nail folds taping with kinesio tape. RESULTS: Long-lasting simple onycholysis with DNB may be fully eliminated by applying the combined pharmacological, orthonyxia and taping treatment. CONCLUSION: Advanced simple onycholysis, which leads to the DNB and, in consequence, to the shortening or narrowing of the nail plate, causes cosmetic discomfort for patients. A damaged nail apparatus is also more susceptible to new traumas. Even long-standing onycholysis with DNB can be successfully treated with easy-to-apply conservative methods. The key point of therapy is the use of several methods of treatment with different effects on the nail apparatus. The effects of described therapy are highly satisfactory, the only drawback being its long term, which is caused by slow growth of the nails.

Nail Changes Associated With Thyroid Disease.

Nail changes with thyroid disease have not been well studied. Nail findings are helpful in early diagnosis of thyroid disorders and therefore are important for dermatologist education. We reviewed the literature on nail changes in thyroid patients and found that onycholysis and slow-growing, thin nails are associated with hypothyroidism and that onycholysis, koilonychia, and brittle nails changes are associated with hyperthyroidism.

Disappearing Nail Bed: Review of Etiology, Grading System, and Treatment Options.

Disappearing nail bed (DNB) is a condition characterized by irreversible epithelialization of the nail bed following long-standing onycholysis. This phenomenon can occur in fingernails and toenails. Factors implicated in the development of DNB include trauma, manicuring, and onychotillomania and dermatologic conditions like psoriasis and dermatitis. Specifically for the toenail, contributing factors also include increasing age, history of trauma, surgery, onychomycosis, and onychogryphosis. A grading system that stages the progression of onycholysis to DNB has been proposed to aid clinicians in the diagnosis and treatment of these conditions. Several methods have been designated for the treatment of DNB.

Onychomycosis: Correlation between the dermoscopic patterns and fungal culture.

BACKGROUND: Onychomycosis is a dermatophyte fungal infection of the nail plate, bed, and the matrix, leading to the gradual damage which often considered a cosmetic problem. Several presentations of onychomycosis: distolateral subungual (DLSOM), superficial white, proximal subungual, endonyx, and total dystrophic (TDOM). Although the diagnosis relies on mycological results, there are three specific dermoscopic findings for onychomycosis: a jagged edge of the onycholytic area, with spikes directed to the proximal fold, white-yellow longitudinal striae in the onycholytic nail plate, and colored parallel bands. AIMS: The objective of this diagnostic cross-sectional study was to evaluate the diagnostic accuracy of dermoscopy as a low-cost tool compared with fungal culture in patients with onychomycosis. PATIENTS/METHODS: This study was carried out on 40 patients with a clinical diagnosis of onychomycosis collected from dermatology outpatient clinic of Alzahraa University Hospital after approval from the research ethics committee of Al-Azhar University. For each patient, dermoscopic imaging of nail was done. And nail scrapings, culture on sabouraud's dextrose agar medium, and dermatophyte test agar medium. Informed written consent was taken from all patients, and the data collected from dermoscopic and laboratory results were statistically evaluated. RESULTS: Concerning the dermoscopic features, longitudinal white striae, jagged proximal edge with spikes, were the most commonly detected in DLSOM and TDOM. Linear edge was exclusive to traumatic onycholysis. Laboratory results: Aspergillus species was the most common detected fungus (45%) followed by Candida (32.5%). CONCLUSION: Dermoscopy could facilitate the diagnosis of onychomycosis and differentiate it from mycologically negative onycholysis.

Onycholysis an early indicator of thyroid disease.

Onycholysis is also referred to plummer's nails is a dermatological nail disorder characterized by spontaneous distal separation of the nail plate from the free margin and progressively proximally. We discuss a case of the 38-year-old man with onycholysis associated with hyperthyroidism due to Graves' disease. In this case review, we will discuss an association of onycholysis with thyroid disease and its diagnostic prognosis. Any unexplained onycholysis should prompt the clinician to investigate the client for asymptomatic hyperthyroidism.

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.

A double-blind, randomised trial of a polyphenolic-rich nail bed balm for chemotherapy-induced onycholysis: the UK polybalm study.

PURPOSE: Nail damage is common amongst patients receiving chemotherapy causing disfigurement and pain. This investigation evaluated whether a topical balm containing steam-extracted, bioactive polyphenolic-rich herbal oils blended with organic waxes could protect the nails via their reported anti-inflammatory, analgesic, anti-oxidant and anti-microbial properties. METHODS: 60 patients (23M, 37F) were randomised to apply (2-3/day) either the plant balm (PB) or a petroleum control (PC) to their nail beds. Demographics, type and number of chemotherapy cycles did not differ between the two groups, recruited between Sept 2015 and Sept 2016. An unpaired t test was used to test the differences in symptoms and physical nail damage between the two groups. RESULTS: Symptom scores recorded with the dermatology life quality questionnaire (DLQQ) were significantly better, between the start and end of chemotherapy, in the group applying the PB versus PC. Likewise, the mean fall in nail damage, scored with the Nail Psoriasis Index by the supervising physician, was also significantly different. CONCLUSION: The polyphenolic-rich essential oils and plant-based waxes in this nail bed balm profoundly reduced chemotherapy-related nail damage and improved nail-related quality of life, compared to a control. A further analysis is planned combining this balm with nail bed cooling.
