Keratosis Pilaris Treatment: Evidence from Intervention Studies.

Keratosis pilaris is a common dermatosis observed in daily dermatologic practice. The diagnosis is clinical and usually asymptomatic, although sometimes patients may complain of mild pruritus and its cosmetic appearance. Few reports exist about its treatment. There are clinical trials assessing topical treatments and laser surgery, but no systematic reviews on its management were found in literature. An online research was conducted to identify evidence-based recommendations. Lactic acid, salicylic acid, and the 1064-nm Nd:YAG laser seem to be the most effective and safe treatment options for keratosis pilaris among patients aged 12 years and older; however, high-quality randomized controlled trials with long-term outcomes are required.

[Adverse cutaneous reactions to drugs]. / Reacciones cutáneas adversas a medicamentos.

Adverse cutaneous reactions to drugs are any undesirable change in the structure or function of the skin. These are among the adverse side effects to common drugs. The most commonly implicated drugs are antibiotics and anticonvulsants. Cutaneous clinical manifestations are diverse ranging from mild or moderate reactions, such as urticaria and maculopapular rash, to severe cutaneous adverse reactions (SCAR), which are known due to their high morbidity and mortality (among these: Stevens-Johnson syndrome, toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). The clinical pattern, etiology, prognosis and treatment differ among these skin reactions, which is why it is necessary a clear diagnosis based on a comprehensive clinical examination, skin biopsy, and specific laboratory tests. The therapeutic options depend on the clinical diagnosis. For all reactions, a symptomatic and adequate supportive therapy is necessary; in some cases, a systemic immunomodulatory therapy can be useful.

Las reacciones cutáneas adversas a medicamentos son cualquier cambio indeseable en la estructura o función de la piel. Estas figuran entre los efectos adversos secundarios a medicamentos más comunes. Los grupos de fármacos más frecuentemente implicados son los antibióticos y los anticonvulsivantes. Las manifestaciones clínicas cutáneas son diversas y abarcan desde las reacciones leves o moderadas, como es el caso de la urticaria y el exantema maculopapular, hasta las reacciones cutáneas adversas severas, que son conocidas por su alta morbilidad y mortalidad, por ejemplo, el síndrome de Stevens Johnson, la necrosis epidérmica tóxica (NET) y el síndrome de hipersensibilidad, denominado reacción a fármacos con eosinofilia y síntomas sistémicos (DRESS). El patrón clínico, la etiología, el pronóstico y el tratamiento difieren entre estas reacciones cutáneas, por lo que es necesario un diagnóstico claro basado en un examen clínico exhaustivo, biopsia de piel y estudios de laboratorio. Las opciones terapéuticas dependen del diagnóstico clínico. Para todas las reacciones es necesario un tratamiento adecuado de soporte; en algunos casos puede utilizarse terapia inmunomoduladora.
