Treatment of nail psoriasis with Pulse Dye Laser plus calcipotriol betametasona gel vs. Nd:YAG plus calcipotriol betamethasone gel: An intrapatient left-to-right controlled study.

BACKGROUND: Treatment of nail psoriasis remains a challenging and often disappointing situation. OBJECTIVE: To compare the efficacy, adverse reactions and tolerability of treatment of nail psoriasis with PDL vs. Nd:YAG, in association with betametasona calcipotriol gel. METHODS: An open, prospective intrapatient left-to-right study was designed. The right hand of each patient received treatment with PDL and the left hand with Nd:YAG. Betamethasone calcipotriol gel was applied once a day during the first week after each laser session. A total of four sessions were administered. RESULTS: The clinical efficacy was evaluated according to the NAPSI score. All patients showed improvement in nail bed and nail matrix psoriasis. The global NAPSI mean declined in 15.46 (p<0.000). There was neither statistical difference between the reduction in nail bed and matrix NAPSI nor in the treatment with PDL vs. Nd:YAG. The administration of Nd:YAG was more painful. No serious adverse effects were documented. LIMITATIONS: No random assignment and the small number of patients. CONCLUSIONS: PDL and Nd:YAG have proven to be an effective treatment for nail psoriasis with no serious adverse effect. No statistically significant difference was found between the two treatments.

[Ultrasound in the management of nail disease]. / Ecografía aplicada al manejo de la patología de la uña.

Nail diseases are a diagnostic challenge and high-frequency ultrasound with colour Doppler is a simple and painless diagnostic test that can often be useful. Ultrasound allows real-time evaluation of the anatomical structures of the nail and its vascularisation. The present study reviews the literature on ultrasound findings in the normal nail and in inflammatory and tumoural disease.

Effect on Nail Structure and Transungual Permeability of the Ethanol and Poloxamer Ratio from Cyclodextrin-Soluble Polypseudorotaxanes Based Nail Lacquer.

Aqueous-based nail lacquers have shown potential in promoting the diffusion of drugs into the nail. In our laboratory, we have recently developed a transungual delivery system based on an aqueous dispersion of cyclodextrin-poloxamer soluble polypseudorotaxanes, supramolecular host-guest assemblies that improves the drug permeation into the nail. However, the high-water content and the rheological and adhesive properties of this lacquer negatively affect properties that play a fundamental role in the patients' acceptance such as stickiness, nail film formation or drying rate, properties. In this work, we have optimized the composition of these lacquers to improve these properties whilst maintaining good drug permeation profiles. Incorporating ethanol into the vehicle and reducing the proportion of Poloxamer 407 (PL), provided a good strategy. The use of hydro-ethanolic mixtures (>50% ethanol) and the reduction of the poloxamer concentration significantly improved the lacquer drying speed by reducing the stickiness and promoting film formation on the nail surface. Additionally, in a surprising way, the use of hydro-ethanolic vehicles further enhanced the permeation of ciclopirox olamine and clobetasol propionate, used for the treatment of onychomycosis and nail psoriasis respectively, into the nail and hooves.

Qué debe saber el reumatólogo del compromiso de piel para el manejo de la artritis psoriática / Which must be known by the rheumatologist of the skin commitment for the management of psoriatic arthritis

La artritis psoriática es una patología inflamatoria crónica que puede afectar a articulaciones periféricas y/o axiales, las que pertenecen al “espectro psoriático”. Es una enfermedad subdiagnosticada y subtratada, que puede traer consecuencias funcionales, laborales y de calidad de vida en los individuos que la padecen. Se estima que el 30 por ciento de los pacientes con psoriasis presentan compromiso articular. Entre los factores de riesgo para desarrollarla se encuentran; psoriasis cutáneas severas, evolución prolongada de más de 10 años, obesidad y psoriasis ungueal. Esta última puede presentar alteraciones de la matriz y/o del lecho ungueal, las que se pueden manifestar aisladamente o en conjunto. El diagnóstico de la artritis psoriática y de la psoriasis ungueal puede representar un verdadero desafío. Es de gran relevancia el diagnóstico temprano y el tratamiento correcto, ya que permiten preservar una mejor funcionalidad y calidad de vida de los pacientes.

Psoriatic arthritis is a chronic inflammatory pathology that can affect both axial and peripheral joints, belonging to the “psoriatic spectrum”. It is an underdiagnosed and undertreated condition, which can bring functional, labor and quality of life consequences in individuals suffering from it. About 30 percent of patients with psoriasis also have joint involvement. Risk factors for developing the disease include severe cutaneous psoriasis of more than 10 years, obese patients and nail psoriasis. Within the nail psoriasis, there are manifestations of the nail matrix and the nail bed, which can be manifested in isolation or in conjunction. However, the differential diagnosis of these lesions and psoriatic arthritis itself can be a real challenge. Early diagnosis and correct treatment depend to a large extent on our patients having better functionality and quality of life.

Psoriasis ungueal: experiencia con el tratamiento combinado de clobetasol al 8 por ciento en laca ungueal y calcipotriol / Combined clobetasol and calcipotriol treatment for nail psoriasis

La psoriasis ungueal es un problema común en los pacientes psoriáticos, con una incidencia de vida de 90%. A pesar de su alta incidencia y del gran impacto que produce en la calidad de vida, ha sido poco estudiada y el tratamiento óptimo aún no está bien dilucidado. Los corticoides tópicos y los análogos de la vitamina D son las terapias más usadas, pero no existe un esquema estándar para su uso. La combinación de estos agentes se ha estudiado en los últimos años para pacientes con afectación de la matriz y del lecho ungueal, mostrando muy buenos resultados. El caso que presentamos demuestra la sinergia entre estos agentes.

Nail psoriasis is a common problem among psoriatic patients, with a lifetime incidence of 90%. Despite its high incidence and severe impact on the quality of life, it has not been fully studied and the optimal treatment is still unclear. Topical glucocorticosteroids and vitamin D analogues are the most used therapies, but there is no standard therapeutic regimen for their use. The combination of both of these agents has been studied during the last years for the treatment of patients with matrix and bed nail compromise, showing very good results. The case that we present shows the synergy between these agents.
