Colgajo en isla del labio superior: claves fundamentales y serie de casos / Island Flap for Upper-Lip Reconstruction: Analysis of Key Aspects and a Case Series

La reconstrucción del labio superior tras la cirugía de Mohs supone, en ocasiones, un reto para el cirujano dermatológico. Presentamos una serie de 15 pacientes (7 hombres y 8 mujeres; edad media de 65,6 años) con cáncer cutáneo (10 carcinomas basocelulares, 2 melanomas y 3 carcinomas escamosos) localizados en el labio superior intervenidos mediante cirugía de Mohs con defectos resultantes de 3-7,6 cm. Para la reconstrucción se empleó un colgajo en isla del labio superior diseñado escondiendo las incisiones en el pliegue nasolabial, en la línea de unión del bermellón con la piel y en las líneas de tensión de la piel relajada. Se explican las claves del diseño y la cirugía, enfatizando en la importancia de sacrificar en ocasiones pequeñas zonas de tejido sano. Se alcanzaron resultados satisfactorios cosméticos y funcionales, sin complicaciones posquirúrgicas en todos los pacientes

Upper-lip reconstruction after Mohs micrographic surgery is challenging for dermatologic surgeons. We describe a series of 15 patients (7 men and 8 women; mean age, 65.6 years) with skin cancer on the upper lip treated with Mohs surgery: 10 were basal cell carcinomas, 2 were melanomas, and 3 were squamous cell carcinomas. The resulting defects measured between 3 and 7.6cm. We used island flaps to reconstruct the defects in all cases, hiding the incisions in the nasolabial fold, at the line where the skin meets the vermillion border of the lip, and in the relaxed skin tension lines. We explain key aspects of the surgeries and design of the reconstructions, with emphasis on the importance of occasionally sacrificing small areas of healthy skin. Cosmetic and functional outcomes were satisfactory in all patients, and there were no postsurgical complications

Chronic rhinosinusitis is associated with prolonged SARS-CoV-2 RNA shedding in upper respiratory tract samples: A case-control study.

BACKGROUND: SARS-CoV-2, the COVID-19 causative agent, has infected millions of people and killed over 1.6 million worldwide. A small percentage of cases persist with prolonged positive RT-PCR on nasopharyngeal swabs. The aim of this study was to determine risk factors for prolonged viral shedding amongst patient's basal clinical conditions. METHODS: We have evaluated all 513 patients attended in our hospital between 1 March and 1 July. We have selected all 18 patients with prolonged viral shedding and compared them with 36 sex-matched randomly selected controls. Demographic, treatment and clinical data were systematically collected. RESULTS: Global median duration of viral clearance was 25.5 days (n = 54; IQR, 22-39.3 days), 48.5 days in cases (IQR 38.7-54.9 days) and 23 days in controls (IQR 20.2-25.7), respectively. There were not observed differences in demographic, symptoms or treatment data between groups. Chronic rhinosinusitis and atopy were more common in patients with prolonged viral shedding (67%) compared with controls (11% and 25% respectively) (P < 0.001 and P = 0.003). The use of inhaled corticosteroids was also more frequent in case group (P = 0.007). Multivariate analysis indicated that CRS (odds ratio [OR], 18.78; 95% confidence interval [95%CI], 3.89-90.59; P < 0.001) was independently associated with prolonged SARS-CoV-2 RNA shedding in URT samples, after adjusting for initial PCR Ct values. CONCLUSION: We found that chronic rhinosinusitis and atopy might be associated with increased risk of prolonged viral shedding. If confirmed in prospective trials, this finding might have clinical implications for quarantine duration due to increased risk of pandemic spread.

Mucocutaneous manifestations of cocaine abuse: a review.

Cocaine is an alkaloid extracted from the leaves of the Erythroxylum coca plant that emerged in the 1970s as a fashionable drug among members of certain social backgrounds. Cocaine abuse is a problem of current interest, which is mostly hidden and underdiagnosed, but dramatically widespread among all socio-economic strata, and with an incidence which is increasing at an alarming rate. There are 1.5 million cocaine consumers in the USA. In Spain, the prevalence of consumption among the population between 15 and 65 years old is higher, reaching 3.1%. Because of this, it seems important to understand and recognize all the mucocutaneous manifestations of cocaine abuse which have been reported in the literature to clarify and to help dermatologists in their daily practice. In this article, we describe the principal mucocutaneous manifestations of cocaine abuse and we review isolated case reports which have been published in the literature. Because the dermatologist may deal with an unknown problem as well as with an already well-known history of cocaine abuse, it seems logical to separate the mucocutaneous manifestations into those which are frequent and highly suggestive, such as those caused by vascular injury, damage to mucosal membranes, infectious diseases or neutrophilic dermatosis, especially when suffered by young people and in consonance with other systemic manifestations and, those which have been reported in the literature as isolated case reports. We also summarize the main aspects of its pathogeny, principal pharmacodynamic and pharmacokinetic characteristics, and diagnostic tools.

De la terapia fotodinámica convencional a la terapia fotodinámica con luz de día en el tratamiento de las queratosis actínicas: revisión sistemática y metaanálisis / Switching From Conventional Photodynamic Therapy to Daylight Photodynamic Therapy For Actinic Keratoses: Systematic Review and Meta-analysis

La queratosis actínica es la lesión precursora de cáncer cutáneo no-melanoma más frecuente. La terapia fotodinámica convencional se ha empleado eficazmente pero requiere tiempo, infraestructuras y es en ocasiones muy dolorosa. En este contexto surge la terapia fotodinámica con luz de día (TFDLD). Con el objetivo de estudiar las evidencias disponibles que evalúan la eficacia y seguridad de la TFDLD frente a la terapia fotodinámica convencional en el tratamiento de pacientes con queratosis actínica/campo de cancerización, y obtener un estimador global de eficacia, realizamos una revisión sistemática de la literatura y un metaanálisis. Se concluye que la variación en eficacia entre ambas terapias es clínicamente irrelevante (estimador global de la diferencia de tasas de respuesta media: -3,69%, IC 95%: -6,54 a -0,84). Con TFDLD el dolor referido es menor (p < 0,001), los efectos adversos locales y leves (el 79% no refiere molestias), los resultados cosméticos buenos-excelentes (>90% de los casos) y la satisfacción del paciente mayor (p < 0,001) (AU)

Actinic keratosis is a precursor lesion to the most common nonmelanoma skin cancer. Conventional photodynamic therapy (PDT) has been shown to be effective, but the procedure is time-consuming, can be very painful, and requires infrastructure. These shortcomings led to the emergence of daylight PDT. To obtain a global estimate of efficacy, we undertook a systematic literature review and performed a meta-analysis of the available evidence on the efficacy and safety of daylight PDT as compared to conventional PDT in the treatment of actinic keratosis and/or field cancerization. The conclusion is that the difference in efficacy is clinically negligible (global estimate of the mean response rate difference, -3.69%; 95% CI, -6.54% to -0.84%). The adverse effects of daylight PDT are mild and localized (79% of patients report no discomfort), and patients report less pain (P < .001). Daylight PDT gives good to excellent cosmetic results in more than 90% of patients, and patient satisfaction is greater (P < .001) (AU)
