A new method to treat onychopapilloma with pulsed dye laser irradiation: a 13-case series report.

Purpose: Onychopapilloma is a rare benign nail tumor affecting the distal matrix and the nail bed. Currently, the only available treatment is surgical resection, which has a recurrence rate of 20% and may lead to various complications. Here we report a new method to treat onychopapilloma with pulsed dye laser (PDL).Materials and methods: We retrospectively analyzed 13 cases and evaluated disease classification, dermoscopic examination, laser treatment parameters, photographs before and after treatment, and treatment outcome.Results: The site distribution of onychopapilloma was consistent with previous reports. PDL treatment was performed with 595 nm laser, with 1.5 ms pulse duration, spot diameter 3-5 mm, and 11.5-13.5 J/cm2 fluence. Irradiation covered the telangiectatic area up to the edge of the nail folds, with the terminal response of purpura occurrence. The overall effective rate was 77%; the effective rates for erythronychia, leukonychia, and melanonychia were 88%, 67%, and 50%, respectively.Conclusions: PDL treatment for onychopapilloma provides an alternative to traditional surgery with comparable effectiveness but much less risk for complications.

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.

Comprehensive treatment of Cronkhite-Canada syndrome: A case report and literature review.

INTRODUCTION: Cronkhite-Canada syndrome (CCS) is currently considered to be a non-hereditary disease, which is relatively rare clinically. It is also known as polyposis hyperpigmentation alopecia nail dystrophy syndrome, it is a syndrome characterized by gastrointestinal polyposis and ectodermal changes, the main manifestations are gastrointestinal symptoms, skin pigmentation, alopecia, and hypothyroidism. CASE PRESENTATION: In this paper, the clinical characteristics, diagnosis and treatment of a case of CCS admitted to Huanghe Sanmenxia Hospital were analyzed. In the course of treatment, traditional Chinese medicine was used, but no hormone, and the patient's clinical symptoms were greatly relieved. CONCLUSIONS: CCS is rare, there is no specific treatment, and traditional Chinese medicine may can greatly relieve the clinical symptoms of patients. However, it's still having to be verified by a large sample, multi-center, long-term treatment follow-up studies.

Successful treatment of a patient with subungual warts using paiteling: A case report.

BACKGROUND: There are many methods to treat subungual wart, but the treatment results are not satisfactory. CASEPRESENTATION: A patient with a 10-year history of subungual warts was cured after using paiteling, and no warts recurred after six months of follow-up. CONCLUSION: Paiteling is effective and safe to treat subungual warts.

Management of Nail Disease in Patients With Psoriatic Arthritis: An Updated Literature Review Informing the 2021 GRAPPA Treatment Recommendations.

OBJECTIVE: Nail psoriasis is common, impairs fine motor finger functioning, affects cosmesis, and is associated with a lower quality of life. This review updates the previous Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) treatment recommendations for nail psoriasis. METHODS: This systematic literature review of the PubMed, MEDLINE, Embase, and Cochrane databases examined the updated evidence since the last GRAPPA nail psoriasis treatment recommendations published in 2014. Recommendations are based on preformed PICO (Patient/Population - Intervention - Comparison/Comparator - Outcome) questions formulated by an international group of dermatologists, rheumatologists, and patient panel members. Data from this literature review were evaluated in line with Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. RESULTS: Overall, there is insufficient evidence to make any recommendation for the use of topical corticosteroids, topical calcipotriol, topical tazarotene, topical cyclosporine, dimethyl fumarates/fumaric acid esters, phototherapy, and alitretinoin. There is a low strength of evidence to support the use of calcipotriol and corticosteroid preparations, topical tacrolimus, oral cyclosporine, oral methotrexate, intralesional corticosteroids, pulsed dye laser, acitretin, Janus kinase inhibitors, and apremilast. CONCLUSION: The highest strength of supporting evidence is for the recommendation of biologic agents including tumor necrosis factor inhibitors, and interleukin 12/23, 17, and 23 inhibitors.

Bacterial nanocellulose patches as a carrier for hydrating formulations to improve the topical treatment of nail diseases.

Bacterial nanocellulose has been widely investigated for wound healing applications, mainly due to its moisturizing capabilities and biocompatibility. Even though the topical therapy of nail diseases could benefit from these properties, this application has not yet been investigated. Therefore, actively hydrating nail patches based on bacterial nanocellulose were developed to improve the delivery of ciclopirox olamine and Boswellia serrata extract through the nail plate. The nanocellulose matrix was used to enable the application of hydration enhancing solutions based on glycerol and urea as a mechanically stable patch. While the favorable mechanical characteristics of the material remained unchanged, an increase of the incorporated glycerol concentration enhanced the transparency and wetting capacity of the patches. A biphasic drug release from the patches could be observed for drug and extract with a faster release for the hydrophilic ciclopirox olamine. High glycerol concentrations correlated with increased cumulative release and permeation through keratin films for drug and extract, demonstrating the hydration driven permeation enhancement. Patches containing ciclopirox olamine showed strong antimycotic effects against relevant pathogens for onychomycosis. The present finding proposed the combination of bacterial nanocellulose with glycerol, urea and different drug as a promising platform for the local treatment of nail diseases.

Anti-IL23for nail psoriasis in real life: Results of efficacy and safety during a 52-week period.

Nail psoriasis (NP) is often considered disfiguring for patients with a relevant impact on quality of life (QoL). It is also difficult to treat for dermatologists who are often frustrated by the scarcity of effective therapeutic alternatives in this particular location. Topical therapies are often used as the first-line treatment for mild NP, but efficacy is the modest. Conventional disease-modifying antirheumatic drugs (cDMARDs) (e.g., cyclosporine, methotrexate, acitretin, and dimethyl fumarate) are generally avoided in NP without general cutaneous involvement. Biologics represent, to date, a concrete possibility for the management of these patients. The data from the clinical trials are encouraging, although there are still few data in real-life. Here, we report a study conducted at Siena University Hospital on 20 patients with NP on both hands and feet treated with anti-IL23 for 52 weeks. No differences were evaluated from baseline to week 4 of anti-IL-23 treatment. NAPSI greatly improved at week 24 with almost 60% of patients reaching NAPSI75 and 40% NAPSI50. At week 52, almost 75% of patients reached NAPSI90. No adverse effects were reported in the patients in the study. The clinical response observed in these patients suggests that treatments that target interleukin-23 may be an effective option for NP, especially when refractory to conventional therapies.

Treatment of nail psoriasis with pulsed dye laser versus combined pulsed dye and Nd:YAG lasers-An intrapatient left-to-right study.

BACKGROUND AND OBJECTIVES: There are limited treatment options for nail psoriasis. It is important to find new therapies and improve existing ones. The aim of this study was to compare the effectiveness of pulsed dye laser (PDL) versus combined PDL and Nd:YAG lasers in patients with nail psoriasis. METHODS: Fourteen patients (with a total of 126 nails affected by nail psoriasis) were treated with PDL (6 J/cm2, 7 mm, 0.45 milliseconds) on both hands and additionally with Nd:YAG (10 J/cm2 , 6 mm, 15 milliseconds) on the right hand. Three treatment sessions were applied at 4-week intervals and patients were followed up for 6 months after the last session. Disease severity was assessed using the Nail Psoriasis Severity Index, both 8- and 32-point variant. Additionally, Dermatology Life Quality Index was assessed before and after treatment. RESULTS: Overall, there was a statistical difference in 8- and 32-point NAPSI score before and after treatment for both hands. However, there was no statistical difference between the score for the right and left hands based on both scale variants. Some aspects of patients' lives showed improvement due to the treatment. CONCLUSIONS: Both PDL in monotherapy and combined Nd:Yag+PDL lasers are safe and effective in treatment of nail psoriasis, although combined therapy shows no advantage over the use of a single laser.

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.

Treating the skin with biologics in patients with psoriasis decreases the incidence of psoriatic arthritis.

OBJECTIVES: To compare the incidence of psoriatic arthritis (PsA) in patients with psoriasis (PsO) according to different treatments for their skin: topics/no treatment, conventional disease-modifying antirheumatic drugs (DMARDs) (cDMARDs) or biological DMARDs (bDMARDs). METHODS: Patients with PsO without PsA followed at a university hospital were included in this retrospective cohort study. Patients were classified according to their treatment in topics (topics, phototherapy or no treatment), cDMARDs (methotrexate and cyclosporine) and bDMARDs (tumour necrosis factor inhibitors (TNFi), interleukin 17 inhibitors (IL-17i) and IL-12-23i ((interleukin (IL) 12/IL-23 inhibitor))) groups. Incident cases of PsA were attributed to one treatment if developed during the administration of that treatment. A Cox proportional hazards model was used to evaluate the adjusted risk of PsA development by treatment group. RESULTS: 1719 patients with PsO contributed a total of 14 721 patient/years (py). 1387 (81%) patients were in the topics, 229 (13%) in cDMARDs and 103 (6%) in the bDMARDs group. During follow-up, 239 patients (14%) developed PsA (231 under topics, six under cDMARDs and two under bDMARDs). Global incidence was 1.6 per 100 py. The risk of developing PsA in patients with PsO treated with bDMARDs was significantly lower (incidence rate ratio (IRR)=0.26; 95% CI 0.03 to 0.94; p=0.0111), compared with topics, but not compared with cDMARDs (IRR=0.35; 95% CI 0.035 to 1.96; p=0.1007). Adjusted Cox proportional hazards regression analysis showed that male sex, nail involvement and higher body max index were associated with increased risk of developing PsA, while biologics use was protective (HR: 0.19; 95% CI 0.05 to 0.81). CONCLUSION: Treatment with biologics in patients with PsO reduced the risk of PsA development.

Biological disease-modifying antirheumatic drugs may mitigate the risk of psoriatic arthritis in patients with chronic plaque psoriasis.

OBJECTIVE: To estimate the incidence of psoriatic arthritis (PsA) in patients with psoriasis who had received a continuous treatment with biological disease-modifying antirheumatic drugs (bDMARDs) compared with phototherapy. METHODS: A retrospective non-randomised study involving patients with moderate-to-severe plaque psoriasis, who were prescribed at least 5 years of bDMARDs or at least three narrow-band ultraviolet light B (nb-UVB) phototherapy courses, and did not have a diagnosis of PsA at enrolment. Development of PsA in each patient was assessed by a rheumatologist according to the Classification for Psoriatic Arthritis criteria. The annual and cumulative incidence rate of PsA was estimated by using an event per person-years analysis. Cox proportional hazards models were undertaken to assess the hazard risk (HR) of PsA after adjustment for confounders. RESULTS: A total of 464 psoriatic patients (bDMARDs, n=234 and nb-UVB, n=230) were followed between January 2012 and September 2020 (corresponding to 1584 and 1478 person year of follow-up for the two groups, respectively). The annual incidence rate of PsA was 1.20 cases (95% CI 0.77 to 1.89) versus 2.17 cases (95% CI 1.53 to 3.06) per 100 patients/year in the bDMARDs versus phototherapy group, respectively (HR 0.29, 0.12-0.70; p=0.006). The variables independently associated with higher risk of PsA were older age (adjusted HR 1.04, 1.02-1.07), nail psoriasis (adjusted HR 3.15, 1.63-6.06) and psoriasis duration >10 years (adjusted HR 2.02, 1.09-3.76); notably, bDMARDs treatment was associated with a lower risk of incident PsA (adjusted HR 0.27, 0.11-0.66). CONCLUSIONS: bDMARDs treatment may delay or reduce the risk of incident PsA in patients with moderate-to-severe chronic plaque psoriasis.

Nail Psoriasis in Older Adults: Intralesional, Systemic, and Biological Therapy.

Psoriasis may affect the skin, scalp, joints, and nails and is common in older adults. Intramatrical injections with triamcinolone acetonide are safe and effective in older individuals. Conventional systemic medications are relatively effective, but side effects, including laboratory abnormalities and drug interactions, are particularly common among older adults. Biologic medications have shown excellent efficacy in treating nail psoriasis. Their safety profile is favorable, but data assessing long-term safety are lacking. Randomized controlled trials in older adults exclusively are necessary to develop evidence-based treatment guidelines in this population.

PLACK syndrome is potentially treatable with intralipids.

We describe an 11-year-old girl with PLACK Syndrome (peeling skin, leukonychia, acral punctate keratosis, cheilitis, and knuckle pads), who was found to have a novel homozygous variant in CAST, the pathogenicity of which was confirmed using blood-derived RNA. There is no established treatment for PLACK syndrome. However, we demonstrate for the first time that this condition is associated with low levels of vitamin A and essential fatty acids, which prompted us to consider a potential treatment strategy. Indeed, we initiated this patient on intravenous lipid infusion (Vitalipid®; an emulsion of fat-soluble vitamins and lipofundin-MCT/LCT 20%) and the response was dramatic. Following the fourth monthly course of treatment, pruritis disappeared and the skin lesions showed remarkable objective improvement. PLACK syndrome is a very rare genodermatosis and only six families have been described to date with pathogenic CAST variants. This is the first report of an objective response to a therapeutic agent, which suggests that PLACK is a potentially treatable condition. The remarkable response we report and the relative safety of the intervention should prompt healthcare providers who care for PLACK syndrome patients to explore this as a potential treatment strategy in future studies.

Iontophoresis to Overcome the Challenge of Nail Permeation: Considerations and Optimizations for Successful Ungual Drug Delivery.

Iontophoresis is a widely used drug delivery technique that has been used clinically to improve permeation through the skin for drugs and other actives in topical formulations. It is however not commonly used for the treatment of nail diseases despite its potential to improve transungual nail delivery. Instead, treatments for nail diseases are limited to relatively ineffective topical passive permeation techniques, which often result in relapses of nail diseases due to the thickness and hardness of the nail barrier resulting in lower permeation of the actives. Oral systemic antifungal agents that are also used are often associated with various undesirable side effects resulting in low patient compliance. This review article discusses what is currently known about the field of transungual iontophoresis, providing evidence of its efficacy and practicality in delivering drug to the entire surface of the nail for extended treatment periods. It also includes relevant details about the nail structure, the mechanisms of iontophoresis, and the associated in vitro and in vivo studies which have been used to investigate the optimal characteristics for a transungual iontophoretic drug delivery system. Iontophoresis is undoubtedly a promising option to treat nail diseases, and the use of this technique for clinical use will likely improve patient outcomes.Graphical abstract.

[Lichenoid drug eruption with antituberculosis drugs associated with an anonychia]. / Toxidermie lichénoïde aux antituberculeux associée à une anonychie.

INTRODUCTION: Lichenoid cutaneous reactions to antituberculosis drugs are rare. Herein we report a new case. PATIENTS AND METHODS: A 41-year-old patient was seen for a profuse and pruriginous rash occurring 2 weeks after administration of rifampicin and isoniazid for pulmonary tuberculosis. Dermatological examination revealed polymorphic erythemato-squamous plaques with lichenoid, psoriatic and eczematous features, associated with cheilitis, erosions on the cheeks and diffuse onychodystrophy. The skin biopsy confirmed a lichenoid reaction. The pharmacovigilance investigation incriminated isoniazid and rifampicin. The patient was treated with topical corticosteroids and UVB phototherapy. The outcome involved complete regression of the eruption but with secondary anonychia. DISCUSSION: Antituberculosis drugs including isoniazid and rifampicin are known to induce lichenoid reactions. It is difficult to distinguish the results from lichen planus. The clinical polymorphism of the rash as well as the patient's drug intake militate in favour of a diagnosis of lichenoid reaction. Widespread ungual involvement, which is extremely rare, warranted early management in order to avert irreversible anonychia.
