Onychomycosis, an infectious disease affecting the nails, can spread within oneself and to others, potentially leading to functional disabilities, therefore achieving a complete cure is necessary. Additionally, shared decision making (SDM) has been gaining attention in the treatment of various diseases in recent years. This study aimed to uncover the realities of patient-physician communication and perception in onychomycosis treatment, particularly in setting treatment goals and the SDM process for selecting therapeutic agents. We conducted a web-based survey of both patients and dermatologists to identify issues in the decision-making process for onychomycosis treatment. The survey revealed several communication challenges between patients and dermatologists regarding onychomycosis treatment. First, a notable percentage of dermatologists do not prioritize a complete cure for onychomycosis in their treatment goals. Second, the dermatologists' treatment explanations tended to emphasize risks, information necessary for appropriate decision-making was not adequately conveyed to patients, and SDM practice was insufficient (the mean scores of SDM-Q-9 and SDM-Q-Doc were 49.0 and 70.9, respectively). Third, dermatologists overestimated the reluctance of older patients to take oral medications. Dermatologists should recognize their patients' expectations for a complete cure for onychomycosis and choose a therapeutic agent that meets patients' needs. Furthermore, dermatologists should explain the benefits and risks of treatment options in a balanced manner, strive for improved patient-physician communication, and aim for a complete cure by administering suitable treatment., (© 2024 Japanese Dermatological Association.)

This article addresses the diagnostic challenges of palmoplantar dermatoses (PPD) within the scope of Primary Health Care (PHC). These common skin conditions, encountered in daily practice, exhibit a diverse range of symptoms and morphologies, complicating their diagnosis. They are etiologically classified into infectious inflammatory, non-infectious inflammatory, and hereditary keratodermas. While various dermatoses may affect the palms and soles, few are specific to this area. Notable examples include palmoplantar pustulosis, dyshidrosis, erythema pernio, and Bazex syndrome. Given the high prevalence of dermatological consultations in PHC, this article underscores the significance of PHC professionals' knowledge regarding these conditions. It proposes a diagnostic algorithm to facilitate their management and timely referral., (Copyright © 2024 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

Rationale: Plantar warts, caused by human papillomavirus (HPV) infection, are a common skin condition on the plantar surface. Despite the availability of various treatments, achieving satisfactory outcomes remains elusive. This study explores a novel therapeutic approach combining traditional Chinese medicine (TCM) soaking therapy with cryotherapy to address this challenge., Patients Concerns: This study focuses on 3 patients who presented with multiple and giant plantar warts, each with a disease duration exceeding 2 years. These patients had undergone numerous unsuccessful cryotherapy treatments, leaving them with persistent and troublesome warts., Diagnoses: All 3 patients were diagnosed with multiple and giant plantar warts caused by HPV infection., Interventions: Following unsuccessful cryotherapies, the patients were administered TCM soaking therapy as an adjunct treatment., Outcomes: Remarkably, all 3 patients achieved complete remission of their plantar warts within 2 to 4 months after combining cryotherapy with TCM soaking therapy., Lessons: Our findings suggest that relying solely on cryotherapy is insufficient for effectively treating plantar warts. The key to successful treatment lies in inhibiting wart proliferation and continuously thinning them, which can be achieved through soaking in TCM. This study demonstrates the potential of combining cryotherapy with TCM soaking as a novel and effective therapeutic approach for treating multiple and giant plantar warts., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Abstract: Multiple pathophysiologic and biomolecular processes lead to bullae, including disruption of adhesion molecules, accumulation of cell injury, and traumatic injury. Blistering disorders of the foot can cause symptoms such as pruritus, pain, and drainage and significantly impact quality of life. Microbiologic and histopathologic examination of tissue specimens should be considered for concerns regarding atypical etiology.This retrospective case series describes patients seen in a community hospital outpatient wound center in southeastern Wisconsin between January 2021 and June 2023 for atypical blistering disorders of the foot. The cases herein describe the history, clinical presentation, and treatment of three atypical blistering disorders of the foot. An 86-year-old man presented complaining of intensely pruritic blistering lesions to both feet. Histopathologic findings indicated eosinophilic infiltrate, and the patient was treated for an eosinophilic drug reaction. A 65-year-old man presented complaining of multiple painful blisters to the plantar aspect of both feet. Histopathologic examination of unroofed blister indicated bullous tinea. Finally, a 44-year-old man with long-standing type 1 diabetes presented complaining of a several-week history of a single blister to his anterior right foot of unknown etiology. The patient was diagnosed with bullosis diabeticorum.Blistering disorders of the foot are diagnostic challenges; diagnostic clarity is assisted by thorough history, clinical presentation, treatment response, microbial analysis, and histopathologic findings., (Copyright © 2024 Wolters Kluwer Health, Inc.

Onychomycosis is a fungal infection of the nail, and the most common nail infection worldwide, causing discoloration and thickening of the nail plate. It is predominantly caused by dermatophytes. Clinical presentation is polymorphous. Diagnosis must be confirmed by mycological examination before initiating any therapy. Management is an ongoing challenge, often requiring several months' treatment, with a high risk of recurrence. Treatment must be adapted to clinical presentation and severity and to the patient's history and wishes. Debridement of all infected keratin is the first step, reducing fungal load. Systemic treatments are more effective than topical treatments, and combining the two increases the cure rate. Terbinafine is the drug of choice for dermatophyte onychomycosis, due to low drug interaction and good cost-effectiveness. Itraconazole and fluconazole are broad-spectrum antifungals that are effective against dermatophytes, yeasts, and some non-dermatophytic molds. Recurrence rates for onychomycosis are high. Prophylactic application of topicals and avoiding walking barefoot in public places may help prevent recurence., (Copyright © 2024 SFCM. Published by Elsevier Masson SAS. All rights reserved.)

Background: Dermatophytoma, also described as a longitudinal streak/spike, is a form of onychomycosis that presents as yellow/white streaks or patches in the subungual space, with dense fungal masses encased in biofilm. This scoping review of the literature was conducted to address a general lack of information about the epidemiology, pathophysiology, and treatment of dermatophytomas in onychomycosis., Methods: A search was performed in the PubMed and Embase databases for the terms "longitudinal spike" or "dermatophytoma." Outcomes of interest were definition, prevalence, methods used for diagnosis, treatments, and treatment efficacy. Inclusion and exclusion of search results required agreement between two independent reviewers., Results: Of a total of 51 records, 37 were included. Two reports provided the first unique definitions/clinical features of dermatophytomas. Overall, many descriptions were found, but one conclusive definition was lacking. Prevalence data were limited and inconsistent. The most frequently mentioned diagnostic techniques were clinical assessment, potassium hydroxide/microscopy, and fungal culture/mycology. Oral terbinafine and topical efinaconazole 10% were the most frequently mentioned treatments, followed by topical luliconazole 5% and other oral treatments (itraconazole, fluconazole, fosravuconazole). In studies with five or more patients without nail excision, cure rates were highest with efinaconazole 10%, which ranged from 41% to 100% depending on the clinical and/or mycologic assessment evaluated. Other drugs with greater than or equal to 50% cure rates were topical luliconazole 5% (50%), oral fosravuconazole (57%), and oral terbinafine (67%). In studies that combined oral terbinafine treatment with nail excision using surgical or chemical (40% urea) methods, cure rates ranged from 50% to 100%., Conclusions: There is little published information regarding dermatophytomas in onychomycosis. More clinical research and physician education are needed. Although dermatophytomas have historically been considered difficult to treat, the efficacy data gathered in this scoping review have demonstrated that newer topical treatments are effective, as are oral antifungals in combination with chemical or surgical methods.
