RESUMO
"Green nails" or chloronychia results from an infection mostly caused by Pseudomonas sp. but also from other bacterial or fungal contamination. Its presents as a typical triad: green discoloration of the nail plate with proximal chronic paronychia and disto-lateral onycholysis. In a moist environment, Pseudomonas colonizes onycholysis of any origin (traumatic, inflammatory or tumoral). Nail color varies from pale green to dark green, almost black. Treatment consists in cutting of the detached nail plate, brushing the nail bed with a 2% sodium hypochlorite solution twice daily accompanied by moisture eviction by wearing latex gloves over cotton ones for all daily household tasks.

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.

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.

BACKGROUND: Hallux Valgus (HV) deformity is associated with misalignment in the sagittal plane that affects the first toe. However, the repercussions of the first toe hyperextension in HV have been scarcely considered. The purpose of this study was to provide evidence of the association between first-toe hyperextension and the risk of first toenail onycholysis in HV. METHODS: A total of 248 HV from 129 females were included. The extension of 1st MTP joint was measured while the patient was in the neutral position of the hallux using a two-branch goniometer. The classification of the HV severity stage was determined by the Manchester visual scale, and the height of the first toe in the standing position was measured using a digital meter. An interview and clinical examination were performed to collect information on the presence of onycholysis of the first toe. RESULTS: Of the 248 HV studied, 100 (40.3%) had onycholysis. A neutral extension > 30 degrees was noted in 110 (44.3%) HV. The incidence of onycholysis was higher in HV type C than in type B (p = 0.044). The probability of suffering onycholysis in the right foot was 2.3 times greater when the neutral position was higher than 30 degrees (OR = 2.3; p = 0.004). However, this was not observed in the left foot (p = 0.171). Onycholysis was more frequent in HV with more than 2 cm height of the first toe (p < 0.001). For both feet, the probability of suffering onycholysis was greater for each unit increase in hallux height (right foot OR = 9.0402, p = 0.005; left foot OR = 7.6633, p = 0.010). CONCLUSIONS: The incidence of onycholysis appears to be significantly associated with HV showing more than 30º extension, and more than 2 cm height of the first toe. Height and hyperextension of the first toe together with first toenail pathology should be mandatory in the evaluation of HV.

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.

BACKGROUND: Nail involvement in subepidermal autoimmune blistering diseases (SEABD) is not common. Although these changes can be transient, permanent changes can also occur. This study addresses nail involvement manifestations and their associated factors in patients with SEABD. METHODS: From March 2020 to March 2021, we enrolled 56 patients with SEABD who were being examined at a tertiary skin hospital and checked their nail changes. We investigated the association between the SEABD subtypes and treatments that patients were receiving and the nail abnormalities. Additional factors including age, gender, duration since diagnosis, presence of mucosal involvement, and anti-bp230 and anti-bp180 IgG antibody quantitative levels (in those patients with bullous pemphigoid) were analyzed. RESULTS: The most common nail abnormalities were ridging, onycholysis, and onychoschizia. We observed a lower prevalence of onycholysis in EBA, a lower prevalence of periungual bullae in MMP, and a higher prevalence of scarring loss in EBA. Rituximab and dapsone were effective in preventing onycholysis as well as prednisolone in preventing subungual hematoma. Multiple lesions were found to be more common in the foot digits including great toes, probably because of higher exposure to trauma. CONCLUSIONS: In summary, in patients with SEABD and concomitant nail involvement, the underlying disease control, proper treatment, and avoidance of trauma may be helpful.

BACKGROUND: Nail changes are among the most common dermatological adverse events in paclitaxel-receiving patients. Although effective, low-temperature prophylactic cryotherapy is discomforting and a potential cause of side effects, resulting in low patients' adherence. PATIENTS AND METHODS: A phase II single-arm study evaluating mild cryotherapy for the reduction of 12-week, grade 2 nail toxicity was conducted on 67 taxane-naïve breast cancer patients (age 18-74 years) undergoing weekly adjuvant chemotherapy with paclitaxel. Instant-ice packs were fixed over the fingers and toes for a total of 70 minutes during paclitaxel infusion at a temperature between -5 °C and +5 °C. Nail toxicity was evaluated weekly (CTCAE vs 4.03), including grade 2 (ie, onycholysis, subungual hematoma, onychomadesis) and grade 1 nail toxicities. RESULTS: Twelve patients experienced grade 2 nail toxicities (17.9%, 95% confidence interval [CI] 9.6%-29.2%; median time to onset: 56 days): onycholysis was the most frequent grade 2 toxicity (13.4%), followed by subungual hematoma (9.0%) and onychomadesis (1.5%). Grade 1 toxicity occurred in 33 patients (63.5%, 95% CI 49.0%-76.4%) with nail discoloration representing by far the most frequent toxicity (59.6%). Seventeen patients (25.4%) reported no nail toxicity. 62.7% of patients reported no pain and 22.4% suffered moderate pain. No patient experienced severe pain or others adverse effects. CONCLUSIONS: Instant-ice pack is a feasible prophylactic intervention for nail toxicity, well tolerated by patients and with limited impact on routine workload. It could be considered for patients refusing (or interrupting) cryotherapy, and it can be implemented when frozen gloves management is not feasible.

OBJECTIVES: Spacesuits are designed to be reliable personal spacecraft that preserve the life and well-being of the astronaut from the extremes of space. However, materials, operating pressures, and suit design requirements often result in a risk of musculoskeletal discomfort and injury to various areas of the body. In particular, this investigation looked at fingernails and their risk of developing onycholysis. METHODS: An onycholysis literature review was followed by a retrospective analysis of injury characteristics, astronaut suited training and spaceflight events, hand anthropometry, glove sizing, and astronaut demographics. Multiple logistic regression was used to assess the likelihood of onycholysis occurrence by testing potential risk variables against the dataset compiled from the retrospective data mining. RESULTS: The duration of event exposure, type of glove used, distance (delta) between the fingertip and the tip of the glove, sex, and age were found to be significantly related to occurrence of onycholysis (whether protective or injurious). CONCLUSION: An initial risk formula (model) for onycholysis was developed as a result of this investigation. In addition to validation through a future study, further improvement to this onycholysis equation and spacesuit discomfort and injury in general can be aided by future investigations that lead to better definition of the threshold between safe and risky exposure for each type of risk factor. APPLICATION: This work described a potential method that can be used for EVA spacesuit glove onycholysis injury risk analysis for either iterative glove design or between glove comparisons, such as during a product downselect process.

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.

Onycholysis and paronychia has been associated with chemotherapy treatment for women with breast cancer. Our primary aim was to investigate the effectiveness of different topical interventions to ameliorate nail toxicity. Secondary aims were to explore the full range and severity of possible nail changes associated with taxane-based chemotherapy and the specific impact this had on quality of life, using two novel measures. This was an exploratory randomised controlled trial of three topical interventions (standard care, nail polish or specialist nail drops) for the prevention or reduction of nail changes induced by taxane-based chemotherapy. Outcomes included nail toxicity assessed at three time points (baseline, 3 weeks and 3 months post completion of chemotherapy) using two novel clinical tools (NToX-G12, NToX-QoL) and the Common Terminology Criteria for Adverse Events (CTCAE v3) and EQ-5D-5L. A total of 105 women were recruited (35 in each arm) and monitored up to three months post completion of chemotherapy. Almost 20% of patients were over the age of 60 years. There were 26 withdrawals, the majority from the nail polish arm. Residual Maximum Likelihood REML analysis indicated a significant arm, time and interaction effect for each intervention (p < 0.001). Less nail toxicity was observed in patients receiving specialist nail drops or standard care arms in comparison to those using nail polish. This study provides evidence to support clinicians' suggestions on nail care recommendations based on the patients' needs and preferences. Future investigations into comparing or combining cryotherapy and topical solutions that can support patient's decisions are warranted.

BACKGROUND: Glomus tumours (GTs) are benign cutaneous neoplasms derived from the neuromyoarterial apparatus with a strong predilection for acral sites, especially the subungual space. Current data regarding dermoscopy of these lesions are very limited. OBJECTIVES: To analyse the dermoscopic structures and patterns seen in a large series of subungual (SUGTs) and extraungual glomus tumours (EUGTs) and to determine their diagnostic significance. METHODS: Clinical and dermoscopic images of 86 histopathologically proven cases of GTs (47 SUGTs and 39 EUGTs) collected from 9 hospitals in Spain, France, Italy, and Brazil were evaluated for the presence of dermoscopic structures and patterns. Similarly, 189 and 185 dermoscopic images of other ungual tumours and other extraungual non-pigmented tumours, respectively, were evaluated for the same structures and patterns. Finally, we evaluate diagnostic testing accuracy calculating sensitivity (S), specificity (Sp), and positive and negative predictive values of the different patterns for the diagnosis of GT. RESULTS: Regarding SUGTs, four patterns were built from the combination of different structures. The pattern composed of a structureless purplish/red subungual spot with or without vessels reached the highest S (S1, 78.8%). The combination of a structureless purplish/red subungual spot and longitudinal erythronychia (LE) (S2) is highly specific (96.3%). Patterns S3 (proximal purplish/red subungual spot, LE, and distal notch) and S4 (bed subungual spot and onycholysis) are the most specific and exclusive of matrix and bed tumours, respectively. The most consistent pattern in EUGTs is composed of a structureless purplish-white to reddish-white homogeneous area and linear unfocused vessels (E) (S: 61.5%, Sp: 95.7%). EUGTs did not show lacunae, unlike other vascular tumours. CONCLUSIONS: Dermoscopy is helpful in improving the diagnostic accuracy of GTs, not only in SUGTs but also when these lesions arise out of the ungual apparatus.

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 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 (AU)
