Tratamiento de la rosácea ocular: revisión práctica desde un enfoque interdisciplinario / Treatment of ocular rosacea: A practical review from an interdisciplinary approach

La rosácea es una enfermedad crónica e inflamatoria que afecta principalmente la piel, aunque más de la mitad de los casos también presentan síntomas oculares. Estos pueden ir desde blefaritis hasta conjuntivitis y queratitis. Representa un motivo de consulta frecuente con un impacto psicosocial y en la calidad de vida; su manejo compete tanto a oftalmólogos, dermatólogos y médicos de primer contacto. Para esta investigación, se llevó a cabo una búsqueda en varias bases de datos, incluyendo Medline, Embase, Cochrane y Google Scholar. Se utilizó el término MeSH «rosácea» junto con otras palabras clave relevantes, como «rosácea ocular», «manejo», «tratamiento» y «guías». Se revisaron los artículos disponibles. Las principales guías internacionales y locales recomiendan iniciar el manejo con cambios en el estilo de vida, con especial énfasis en la higiene ocular y evitación de desencadenantes. Como siguiente paso, se recomienda el tratamiento tópico u oral, siendo la ciclosporina tópica, la azitromicina tópica, el tacrolimús tópico y la doxiciclina oral los tratamientos más respaldados por la evidencia. Se recomienda combinar tratamientos. Las guías de manejo actuales se concentran principalmente en las manifestaciones cutáneas y generan pocas directrices sobre el tratamiento oftalmológico. La mayoría de las recomendaciones son emitidas por expertos. En este trabajo, se comparan las guías de tratamiento locales e internacionales de la rosácea, así como otra literatura médica disponible, y se sugiere un esquema de tratamiento práctico e interdisciplinario para la afección ocular basado en la bibliografía revisada (AU)

Rosacea is a chronic and inflammatory disease that primarily affects the skin, although more than half of cases also present with ocular symptoms ranging from blepharitis to conjunctivitis and keratitis. It represents a frequent reason for consultation with a psychosocial impact, affecting quality of life, and requires management involving ophthalmologists, dermatologists, and primary care physicians. For this paper, a search was conducted in several databases, including Medline, Embase, Cochrane, and Google Scholar, using the MeSH term “rosacea” in conjunction with other relevant keywords such as “ocular rosacea”, “management”, “treatment”, and “guidelines”. Available articles were reviewed. International and local guidelines recommend initiating the management of rosacea with lifestyle changes, including ocular hygiene and avoidance of triggers. Topical or oral treatment is recommended as the next step, with topical cyclosporine, topical azithromycin, topical tacrolimus, and oral doxycycline being the treatments most supported by evidence. Combination treatments are also recommended. Current management guidelines mainly focus on cutaneous manifestations, generating few guidelines on ophthalmologic treatment, and most recommendations are issued by experts. This work compares local and international treatment guidelines for rosacea, as well as other available medical literature, and suggests a practical and interdisciplinary treatment scheme for ocular involvement based on the reviewed bibliography (AU)

Not all that glitters is COVID-19: a case series demonstrating the need for histopathology when skin findings accompany SARS-CoV-2 infection.

BACKGROUND: Descriptions of cutaneous findings associated with COVID-19 have not been consistently accompanied by histopathology or confirmatory testing for SARS-CoV-2. OBJECTIVE: To describe and classify the cutaneous findings with supporting histopathology of confirmed COVID-19 inpatients. METHODS: We included consecutive inpatients with a confirmed diagnosis of COVID-19 for whom a dermatology consult was requested. A skin biopsy was performed in all cases. Skin findings were classified as being compatible with a cutaneous manifestation of COVID-19 or as representing a distinct clinical entity. RESULTS: Twenty-eight patients were studied in whom thirty-one dermatologic diagnoses were made. Twenty-two of the dermatoses were compatible with a cutaneous manifestation of COVID-19; nine entities were not associated with infection by SARS-CoV-2. The most common COVID-19-associated pattern was an exanthematous presentation. In four patients, a new pattern was observed, characterized by discrete papules with varied histopathological findings including a case of neutrophilic eccrine hidradenitis. No cases of pernio-like lesions were identified. Skin findings not associated with COVID-19 represented 29% of diagnoses and included Malassezia folliculitis, tinea, miliaria and contact dermatitis. LIMITATIONS: There is no gold-standard test to distinguish between viral exanthems and drug reactions. CONCLUSION: A histopathological study is critical before attributing skin findings to a manifestation of COVID-19.

[CD-34 expression in elastofibroma. Clinicopathological, histochemical, and immunohistochemical study of four cases]. / Expresión de CD-34 en el elastofibroma. Estudio clinicopatológico, histoquímico e inmunohistoquímico de cuatro casos.

OBJECTIVE: To explore the immunohistochemistry of elastofibromas and to evaluate four elastic strain methods for the histological diagnosis of elastofibroma. MATERIAL AND METHODS: Four elastofibromas were obtained from the surgical pathology files of the ABC Medical Center. All patients were women whose lesions were present in the subescapular region. Immunohistochemistry was performed for CD34, actin, desmin, vimentin, S-100 protein and bcl-2 and four elastic stain methods were evaluated (Verhoff, Gallego's, Reyes-Mota and Russel-Movat). RESULTS: In the four cases there were numerous miofibroblasts (vimentin/actin/desmin positive). An unpreviously reported positive CD34 dendritic cells, were present diffusely in all four cases. Verhoff and Reyes-Mota stains remains the most useful methods to reveal the elastic fibers. Russel-Movat method may be use to contrast different connective tissue components. CONCLUSION: The cell of elastofibromas were originally considered fibroblasts. The presence of actin/desmin/vimentin suggests that they are miofibroblasts. We describe for the first time, variable numbers of CD34(QBend/10) positive spindle shaped and dendritic cells in all elastofibromas. These cells may be a reactive population of cells of the "dendritic cell system". There was no immunoreactivity for bcl-2 in these cells.
