Nails in older adults.

As the world's population of adults greater than 60 years old continues to increase, it is important to manage nail disorders that may impact their daily lives. Nail disorders may have significant impact on quality of life due to decreased functionality, extreme pain, or social embarrassment. In this review, we discuss nail disorders affecting older patients, including physiologic, traumatic, drug-induced, infectious, environmental, inflammatory, and neoplastic conditions. Diagnosis of these conditions involves a detailed history, physical examination of all 20 nails, and depending on the condition, a nail clipping or biopsy and/or diagnostic imaging. Nails grow even more slowly in older adults compared to younger individuals, and therefore it is important for accurate diagnosis, and avoidance of inappropriate management and delay of treatment. Increased awareness of nail pathologies may help recognition and management of nail conditions in older adults.

Nail disorders are common amongst older adults and may cause decreased functionality, pain, psychosocial problems and impact quality of life.Many nail conditions, both physiologic or pathologic, may have similar presentation in older adults. Confirmation testing is important to avoid inappropriate or delayed treatment.The increased frequency of comorbidities, drug interactions, polypharmacy, and mental or physical limitations with aging must be considered when managing care of older patients with nail disorders.

Traquioniquia, ¿de qué se trata? / Trachyonychia, what is it about?

La traquioniquia es una afección ungueal de diagnóstico clínico y buen pronóstico, pero se ha de tener en cuenta que bajo su apariencia pueden subyacer otras enfermedades. Antes de plantear su tratamiento, es necesario valorar cómo afecta a la calidad de vida de los pacientes, ya que tiende a la resolución espontánea. (AU)

Trachyonychia is a nail disorder with good prognosis which diagnosis is clinical but, under this condition could be other diseases. So, before treatment it is necessary to ascertain how it affects patient´s quality of life as spontaneous resolution is possible. (AU)

Approach to nail trauma for primary care physicians.

OBJECTIVE: To provide an overview and approach to common nail bed injuries seen by primary care practitioners. SOURCES OF INFORMATION: An Ovid MEDLINE literature search was performed using search terms and studies were graded based on level of evidence. MAIN MESSAGE: Nail trauma is common in primary care practice and requires proper and prompt treatment to avoid lasting effects on finger function and cosmesis. When presented with a fingernail injury, primary care physicians should perform a thorough physical examination to determine extent of injury; take a history to rule out notable risk factors; perform a comprehensive neurovascular examination to assess pulp capillary refill, to do a 2-point discrimination, and to compare with an uninjured digit; and evaluate range of motion. Clinical evaluation may require local anesthesia and a tourniquet. Nail bed trauma can present in different ways and includes subungual hematomas, distal phalanx fractures, Seymour fractures, and-in more severe cases-fragmentation or avulsion of the nail bed. Treatment for subungual hematomas where the nail plate is intact does not require nail plate removal and nail bed exploration; however, exploration and repair are indicated for a nail plate injury, a proximal fracture involving the germinal matrix, and a distal phalanx fracture requiring stabilization. CONCLUSION: Fingertips are essential to normal hand function. Nail trauma is common and can be managed by primary care physicians. Shared decision making concerning management is based on the mechanism and extent of the injury and aims to prevent secondary deformities.

Updates in treatment and impact of nail psoriasis.

INTRODUCTION: Nail psoriasis is an inflammatory disorder without a potential scarring outcome, but the nail signs, even the milder ones, can cause discomfort to patients and severely affect their quality of life. Nail psoriasis may be associated with psoriatic arthritis and when it starts during infancy, it may be a predictor of a more severe disease course in adulthood. All these issues contribute to the high economic burden of psoriasis. AREAS COVERED: Nail psoriasis is notoriously difficult to treat, even though new treatments are in continuous development. This paper provides an update on new treatments and address the current gaps in care of nail psoriasis. EXPERT OPINION: A better understanding of the disease pathogenesis and more 'real-life' studies will definitely be helpful to improve treatment results. A lower level of heterogeneity should be advisable among trials when evaluating nail psoriasis. Moreover, the relationship between nail psoriasis and psoriatic arthritis should be the focus of unbiased studies in order to better define the real risk that nail psoriasis patients have to develop arthritis.

Fractional CO 2 Laser versus Fractional CO 2 Laser Plus Betamethasone/Calcipotriol Ointment in the Treatment of Nail Psoriasis.

BACKGROUND: Nail psoriasis has a major negative impact on the physical and psychological aspects of the patient's life. Treatment is often unsatisfactory because of the difficult penetration of the drug into the nail. OBJECTIVE: To compare the efficacy of fractional CO 2 laser monotherapy versus combined fractional CO 2 laser and calcipotriol/betamethasone ointment preparation in treatment of nail psoriasis. PATIENTS AND METHODS: Thirty patients with nail psoriasis with at least 2 affected fingernails were recruited for this study. Target NAPSI (tNAPSI) score was calculated at the start of the study and at 3 months after the last laser session. One affected fingernail of each patient received 6 sessions of fractional CO 2 laser with 4-week intervals. Another affected fingernail of each patient received topical betamethasone/calcipotriol ointment once daily in addition to the 6 fractional CO 2 laser sessions. RESULTS: In the monotherapy group, there was significant improvement in the nail matrix score, nail bed score, and tNAPSI score. In the combined therapy group, there was significant improvement in nail bed score and tNAPSI score, but nail matrix score showed no statistically significant improvement. Overall, there was no statistically significant difference between the 2 studied groups. CONCLUSION: Fractional CO 2 laser can be an effective and promising new treatment for nail psoriasis.

Adult and Pediatric Nail Unit Melanoma: Epidemiology, Diagnosis, and Treatment.

Nail unit melanoma (NUM) is an uncommon form of melanoma and is often diagnosed at later stages. Approximately two-thirds of NUMs are present clinically as longitudinal melanonychia, but longitudinal melanonychia has a broad differential diagnosis. Clinical examination and dermoscopy are valuable for identifying nail findings concerning malignancy, but a biopsy with histopathology is necessary to confirm a diagnosis of NUM. Surgical treatment options for NUM include en bloc excision, digit amputation, and Mohs micrographic surgery. Newer treatments for advanced NUM include targeted and immune systemic therapies. NUM in pediatric patients is extremely rare and diagnosis is challenging since both qualitative and quantitative parameters have only been studied in adults. There is currently no consensus on management in children; for less concerning melanonychia, some physicians recommend close follow-up. However, some dermatologists argue that the "wait and see" approach can cause delayed diagnosis. This article serves to enhance the familiarity of NUM by highlighting its etiology, clinical presentations, diagnosis, and treatment options in both adults and children.

Trachyonychia in childhood: Clinical aspects and outcome.

INTRODUCTION: Trachyonychia means rough, longitudinally ridged nails with a sandy, brittle and thin aspect. It is a rare condition that occurs mainly in children. Studies on trachyonychia are rare. We aimed to describe the clinical aspects and outcome of trachyonychia, as well as its treatment. CASES: Two boys aged 11 and 14 years old and a girl aged 6 years presented with nail dystrophy of the fingers and toes. Patient 1 had also a scaly patch on the glans penis, and patient 2 was atopic. Trachyonychia associated with psoriasis was suspected in patient 1 and the idiopathic form was retained in the other two patients. All patients were treated with topical steroids for a few months. The patients did not show any improvement at the six-month follow-up. Only one patient was contacted again after two years and showed spontaneous healing. COMMENTARIES: The diagnosis of trachyonychia is mainly clinical. In the literature, 62% of pediatric patients had an idiopathic form. However, a strong association was observed between trachyonychia and alopecia areata. Trachyonychia of childhood appears to have a good prognosis, with spontaneous improvement within six months to two years. Therapeutic abstention is the rule.

Nail Psoriasis. / Psoriasis ungueal.

Nail involvement in psoriasis is common. It is seen in up to 80% of patients with psoriatic lesions and may be the only manifestation in 6% of cases. Nail psoriasis is correlated with more severe disease, characterized by earlier onset and a higher risk of psoriatic arthritis. Accordingly, it can also result in significant functional impairment and reduced quality of life. Psoriasis involving the nail matrix causes pitting, leukonychia, red lunula and nail dystrophy, while nail bed involvement causes splinter hemorrhages, onycholysis, oil spots (salmon patches), and subungual hyperkeratosis. Common evaluation tools are the Nail Psoriasis Severity Index (NAPSI), the modified NAPSI, and the f-PGA (Physician's Global Assessment of Fingernail Psoriasis). Treatment options include topical therapy, intralesional injections, and systemic and biologic agents. Treatment should therefore be assessed on an individualized basis according to the number of nails involved, the part of the nail or nails affected, and the presence of concomitant nail and/or joint involvement.

Hair and Nail Conditions: Nail Conditions.

A thorough understanding of nail anatomy can help physicians identify the causes of nail conditions. Observation of changes to the nail can help establish a diagnosis. Patient evaluation should include a physical examination, dermoscopy, and, in some cases, nail biopsy. Onychomycosis is the most common nail condition worldwide, and should be distinguished from other nail conditions with similar manifestations. Empiric onychomycosis treatment without confirmatory tests has been proposed, but studies have shown the cost-effectiveness of testing to prevent inappropriate therapy. Systemic drugs for management include terbinafine and itraconazole. Longitudinal melanonychia is a brown band through the length of the nail. Nail melanoma should be suspected if the band is dark brown-black, is located on a single digit, and occupies 40% or more of the nail plate width. Biopsy with local anesthesia should be performed in patients with suspected nail melanoma or other neoplastic nail conditions. Identification of warning signs of nail melanoma can result in earlier diagnosis and limit potential morbidity and mortality. Nail psoriasis often is overlooked but can affect up to 50% of patients with psoriasis. Nail lichen planus can cause permanent scarring with loss of normal nail anatomy. Other common nail conditions include acute and chronic paronychia, onychocryptosis, onycholysis, Pseudomonas infection (ie, green nails), onychogryphosis, subungual hematoma, and onychomadesis.

Psoriasis ungueal / Nail Psoriasis

La psoriasis ungueal puede afectar al 80% de los pacientes con psoriasis cutánea y puede ser la única manifestación en el 6% del total. Además, se correlaciona con una enfermedad psoriásica más grave, con un inicio más precoz y con una mayor probabilidad de desarrollar artritis psoriásica. Todo ello hace que se asocie a un importante deterioro funcional y a una disminución de la calidad de vida. La psoriasis ungueal que afecta la matriz puede causar piqueteado/pitting, leuconiquia, manchas rojas en la lúnula o distrofia de la lámina, mientras que la afectación del lecho causa hemorragias en astilla, onicólisis, manchas de aceite o salmón e hiperqueratosis subungueal. Los métodos de evaluación comunes son las escalas NAPSI, NAPSI modificada o f-PGA. Actualmente, disponemos de tratamientos tópicos, intralesionales, sistémicos y biológicos, por lo que deberá individualizarse según el número de uñas implicadas, la zona ungueal afectada y la presencia de afectación cutánea y/o articular (AU)

Nail lichen planus: A review of clinical presentation, diagnosis and therapy.

Lichen planus is a multifaceted disease of complex etiopathogenesis. Nails are involved in up to 10% of patients with lichen planus. Although most cases are mild, serious consequences may occur due to rapid progression of the disease, the high risk of scarring, and the resulting irreversible damage to the nail structure. Permanent damage of at least one nail occurs in approximately 4-12% of patients with nail lichen planus. In this narrative review, we emphasize the pathophysiology of nail lichen planus, the emergent nature of the disease, and the spectrum of different clinical manifestations. Diagnosis of nail disease in general, and of nail lichen planus in particular, is rapidly evolving. This review provides a comprehensive account of the non-invasive and invasive diagnostic techniques and treatment options reported in the literature, with emphasis on the efficacy and safety of the drugs used, the associated evidence, and the factors to be taken into account in planning and providing adequate treatment. The role of aesthetic and camouflage options is also summarized.

Optimal diagnosis and management of common nail disorders.

Nail conditions are not only aesthetic concerns, and nail changes may be a clue to an underlying systemic diseases or infection. Without timely treatment, nail diseases can continue to worsen and significantly impair performance of daily activities and reduce quality of life. Examination of the nails is essential at every medical visit, and may uncover important findings. Brittle nail syndrome, onychomycosis, paronychia, nail psoriasis, longitudinal melanonychia, Beau's lines, onychomadesis and retronychia are common nail disorders seen in clinical practice. These conditions stem from infectious, inflammatory, neoplastic and traumatic aetiologies. Though each nail condition presents with its own distinct characteristics, the clinical findings may overlap between different conditions, resulting in misdiagnosis and treatment delays. Patients can present with nail plate changes (e.g. hyperkeratosis, onycholysis, pitting), discolouration, pain and inflammation. The diagnostic work-up of nail disease should include a detailed history and clinical examination of all 20 nail units. Dermoscopy, diagnostic imaging and histopathologic and mycological analyses may be necessary for diagnosis. Nail findings concerning for malignancy should be promptly referred to a dermatologist for evaluation and biopsy. Nail disease management requires a targeted treatment approach. Treatments include topical and/or systemic medications, discontinuation of offending drugs or surgical intervention, depending on the condition. Patient education on proper nail care and techniques to minimize further damage to the affected nails is also important. This article serves to enhance familiarity of the most common nail disorders seen in clinical practice. It will highlight the key clinical manifestations, systematic approaches to diagnosis and treatment options for each nail condition to improve diagnosis and management of nail diseases, as well as patient outcomes.Key messagesNail disease is not only a cosmetic issue, as nail changes can indicate the presence of a serious underlying systemic disease, infection or malignancy.Nail pain and changes associated with NP are physically and emotionally distressing and may contribute to functional impairment and diminished quality of life.LM is a hallmark sign of subungual melanoma and this finding warrants further investigation to rule out malignancy.

Diagnosis and treatment of nail melanoma: a review of the clinicopathologic, dermoscopic, and genetic characteristics.

Nail melanoma (NM) is an important differential diagnosis in patients with longitudinal melanonychia. However, diagnosis is often challenging as it is difficult to differentiate from other pigmented nail disorders. The main challenge for diagnosis is obtaining adequate nail matrix biopsy specimens for histopathological assessment. Furthermore, the histopathological changes in the early stages of NM are subtle and contribute to a delay in diagnosis and care. Therefore, the integration of clinical and histopathological analyses is essential. Clinical and dermoscopic features, such as a broadened width of asymmetric bands in an irregular pattern, with multicolour pigmentation, periungual pigmentation, and continuous growth, are features that support the diagnosis of NM. The essential histological features that must be assessed are cellular morphology, architectural features, melanocyte density, and inflammatory changes. The reported mutations in NMs were BRAF (0-43%), NRAS (0-31%), KIT (0-50%), NF1 (0-50%), and GNAQ (0-25%). Surgery is the primary treatment for NM. The recommended treatment for in situ or minimally invasive NM is functional surgery, but cases with suspected bone invasion should be treated with amputation. Targeted therapy and immunotherapy are indicated for advanced stages of NM. This review summarizes the updated guidelines for the diagnosis and treatment of NM.

Successful treatment of periungual warts with local hyperthermia: report of two cases.

Periungual warts are common warts that grow on the periungual or nail margin, and it's challenging to remove them due to their particular location, causing its high recurrence rate and brings difficulties to the treatments. We successfully cured two cases of stubborn periungual warts by local hyperthermia. A male with warts on his hands and knees and a girl with periungual warts on her fingers received local hyperthermia of 44 °C for 30 min a time. One month after the last treatment, their lesions disappeared entirely and did not relapse during the follow-up period. These two cases showed that local hyperthermia might be a safe and effective method for treating periungual warts in patients with poor traditional treatment.

Nail changes in diabetes.

Diabetes is a common condition that is increasing in incidence worldwide. Although the skin manifestations of this condition are well described, there is scant literature on the associated nail changes. In this review, we describe the various clinical features of nail changes associated with diabetes, which can be broadly divided into infections, vascular changes, neuropathic manifestations and miscellaneous changes, although there is overlap between them. There is no pathognomonic nail alteration, but it is important for clinicians to be aware of the potential nail manifestations in diabetes as they can facilitate investigations and thereby early diagnosis of diabetes, resulting in holistic management of the patient.

Patient-reported outcome measures for patients with nail conditions: a systematic review of the psychometric evidence.

Nail conditions have an impact on appearance, function, and quality of life of patients. Patient reported outcome measures (PROMs) are important tools for evaluating treatment success from the patient perspective. It is important to understand the quality of PROMs to help guide selection of appropriate tools. The aim of this study was to critically appraise the psychometric properties of nail-specific PROMs using COSMIN guidelines. A systematic review was conducted in May 2019 to identify development and validation articles for nail-specific PROMs. Abstracts and subsequent full-texts were screened by two reviewers for eligibility. Data were extracted for study characteristics and psychometric properties. The risk of bias checklist was completed, and ratings applied to psychometric properties as per COSMIN guidelines. Modified Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria were applied based on the risk of bias checklist to assess methodological quality. The review identified 3289 articles of which 430 full-text articles were screened, nine of which met eligibility criteria. Included papers were for seven PROMs and in total reported on 31of 49 possible measurement properties. Of the 31 measurement properties reported, nine (29%) were rated as insufficient or indeterminate. The modified GRADE methodological quality rating was low or very low for 16 (32.7%) measurement properties, and 18 (36.7%) measurement properties were not described by any PROM. Currently there are no nail-specific PROMS available that demonstrate adequate validity, reliability, or responsiveness, according to COSMIN guidelines. Further research is required to assess missing or insufficiently tested measurement properties in all the PROMs identified.

An Evidence-Based Approach to Pediatric Melanonychia.

Melanonychia including melanonychia striata in children poses a diagnostic dilemma. Atypical clinical features often raise the possibility of malignancy, and a nail unit biopsy may be recommended. Commensurate with atypical clinical features, the histopathology may also appear alarming. However, accumulating data illustrate that most cases of melanonychia striata are benign and suggest that an alternate approach is often warranted for pediatric patients. Herein, we review the existing data regarding pediatric melanonychia striata and offer an evidence-based approach to its evaluation and management.
