ABSTRACT

Human papillomavirus (HPV) infection contributes to the pathogenesis of oropharyngeal squamous cell carcinomas. We estimated prevalence and six-month persistence of oral HPV infections among university students ages 18-25 years living in Valencia, Spain, during the 2012-2013 academic year. Participants provided oral rinse samples; HPV-positive subjects provided a follow-up sample. The study included 543 students; 70 (12.9%) women had received HPV vaccination. Prevalence among vaccinees and non-vaccinees were 10.0% (95% CI: 4.1-19.5%) and 6.8% (95% CI: 4.7-9.4%), respectively. All HPV infections among vaccinees were non-typeable genotypes; 59.4% of non-vaccinees had high-risk genotype infections. Follow-up samples were obtained from 36 participants; one vaccinee (whose specimen was non-typeable) and seven non-vaccinees were found to be HPV positive. Among non-vaccinees, six-month persistence was 10.3% (95% CI: 2.2-27.4%); all persistent infections were with high-risk genotypes. Our results, although subject to study limitations, may support the need to implement new public health strategies.

ABSTRACT

Introducción: Los trabajos que determinan la incidencia de cáncer cutáneo no melanoma (CCNM) en la población tratada con psoralenos orales+UVA son heterogéneos, dependen de la localización geográfica de la población estudiada y tienen períodos de seguimiento cortos. El objetivo del trabajo es determinar la seguridad a largo plazo de la PUVAterapia y en concreto determinar la incidencia de CCNM en los pacientes tratados con PUVAterapia oral en el área mediterránea. Material y método: Se ha realizado un estudio longitudinal de seguimiento retrospectivo, recogiendo 234 pacientes tratados con PUVA sistémico entre 1982 y 1996 con un seguimiento hasta mayo de 2017. Se ha calculado la densidad de incidencia de CCNM bruta y ajustada por edad mediante estandarización directa. Resultados: En 22 pacientes se diagnosticaron 50 neoplasias. La prevalencia de CCNM en pacientes tratados con fototerapia fue del 10,3%. El tiempo medio de seguimiento fue de 21 años. la densidad de incidencia bruta-ajustada de CCNM fue de 554,4-183,9 casos/100.000 pacientes tratados-año. La densidad de incidencia bruta-ajustada de carcinoma basocelular fue de 352,3-111,2 casos/100.000 pacientes y la de carcinoma epidermoide de 229-77,7 casos/100.000 pacientes. Conclusión: La incidencia de cáncer cutáneo en los pacientes tratados con PUVAterapia es superior a la descrita en la población mediterránea


Introduction: Studies reporting incidences of non-melanoma skin cancer (NMSC) are heterogeneous, depend on the geographic area of the studied population and are often short-term. The aim of this study is to determine the incidence of NMSC in patients treated with oral PUVA therapy in the Mediterranean area. Material and methods: A retrospective, observational study was carried out with a sample of 234 patients treated with systemic PUVA between 1982 and 1996, carrying out a historical follow-up until May 2017. The incidencedensity rate of CCNM (crude and adjusted) was calculated by direct standardisation. The incidence of CCNM was compared with that reported in the general population in a similar geographical area. Results: 50 neoplasms were diagnosed in 22 patients. The prevalence of CCNM in patients treated with phototherapy was 10.3%. The mean follow-up time was 21 years. The crude-adjusted incidence density rate of CCNM was 554.4-183.9 cases/100,000 treated patients per year. The crude-adjusted incidence density rate of basal cell carcinoma was 352.3-111.2 cases/100.000 patients and of squamous cell carcinoma was 229-77.7 cases /100,000 patients. Conclusion: PUVA therapy is associated with an increased risk of CCNM inthe Mediterranean population

ABSTRACT

Erythromelalgia is a rare disorder characterized by 3 major symptoms: warmth, redness, and burning pain. It involves the feet and, to a lesser extent, the hands, head, and ears. We report the case of a 27-year-old man presenting with a 15-year history of episodes with edema, local hyperthermia, and burning pain of both ears.

ABSTRACT

La acantólisis consiste en la pérdida de conexión entre los queratinocitos de la epidermis como resultado de la destrucción de los desmosomas intercelulares que conlleva a la formación de hendiduras y vesículas intraepidérmicas. La acantólisis aparece clásicamente en la enfermedad de Hailey-Hailey, la enfermedad de Darier, la dermatitis acantolítica transitoria, el grupo de los pénfigos, la infección por herpesvirus o el disqueratoma verrucoso. Además puede ocurrir en el síndrome estafilocócico de la piel escaldada, el impétigo, la queratosis actínica acantolítica o el carcinoma epidermoide acantolítico. Por último, la acantólisis también puede ser un hallazgo incidental. Se ha descrito en multitud de trastornos epiteliales benignos y malignos, lesiones fibrohistiocitarias, lesiones melanocíticas y lesiones inflamatorias. Estos cambios histopatológicos pueden aparecer tanto dentro de la lesión como sobre la piel sana adyacente. La causa de este hallazgo incidental permanece desconocida


Acantholysis is the loss of cohesión between keratinocytes as a result of dissolution of intercellular desmosomal connections, resulting in clefts or intraepidermal vesicles. Acantholysis occurs classically in Hailey-Hailey’s disease, Darier´s disease, transient acantholytic dermatitis, group of penphigus, herpesvirus infection or warthy dysqueratoma. But acantholysis may also occurs in staphylococcal scalded skin syndrome, impetigo, acantholitic actinic keratosis, acantholytic squamous cell carcinoma or being an incidental finding or artifact. Focal incidental acantholysis has been noted as an incidental finding in association with bening and malignant epithelial lesions, fibrohistiocytic lesions, inflammatory lesions, melanocytic lesions and miscellaneous lesions. The pathologic changes either are observed within the lesion or in the immediately adjacent epithelium. The cause of this clinically condition remains to be determined

ABSTRACT

La dermatitis atópica es una dermatosis inflamatoria de curso crónico caracterizada por un intenso prurito. Se trata de una enfermedad multifactorial que resultaría de la interacción de factores genéticos, ambientales, defectos en la función barrera y una serie de factores inmunológicos. La dermatitis atópica afecta sobretodo a la infancia, pero también puede persistir o comenzar en el adulto. Los casos de adultos afectados recogidos en la literatura, hacen referencia casi exclusivamente a aquéllos en los que la enfermedad se inició en la infancia pero que permanece llegada la vida adulta. Sin embargo, debemos tener en cuenta otro subgrupo de pacientes libres de enfermedad durante la infancia en los que el comienzo de la dermatitis ató pica se produce con los años incluso en la senectud. A pesar de que en este subgrupo las lesiones afectan típicamente a flexuras en forma de eczema exudativo o liquenificado, existe un número no despreciable de pacientes con lesiones de distribución o morfología atípica. Revisamos la etiopatogenia, criterios diagnósticos, clínica, diagnóstico diferencial y tratamiento, incidiendo en la terapéutica de la dermatitis atópica severa o refractaria a los tratamientos convencionales


Atopic dermatitis is a highly pruritic chronic inflammatory skin disorder. The disease results from an interaction between susceptibility genes, the host's environment, skin barrier defects and immunologycal factors. It's a common condition that is often thought to predominantly affect infants and children.Reports on adult disease are most exclusively related to the early-onset atopic dermatitis extending into adult life. However; atopic dermatitis may begin for the first time at an adult age, this subgroup is called adult-onset atopic dermatitis.Although a majority of patients has typical flexural distribution and lichenified/ exudative eczematous pattern, a considerable number of patients could have a different distribution and different morphology. Pathogenesis, clinical patterns and distribution, diagnostic criteria, differential diagnosis and management, specially systemic therapies used in severe or resistant cases of atopic dermatitis, are reviewed

ABSTRACT

El eberconazol es un compuesto imidazólico de aplicación tópica con actividad fungistática y fungicida a altas dosis, de amplio espectro de acción, caracterizado por poseer una estructura molecular de tipo hidrófilo-lipófilo que favorece la penetrabilidad y la permanencia en la piel. Los componentes galénicos de este azol tópico favorecen y optimizan la acción del fármaco en la piel. Los ésteres de ácidos grasos facilitan la penetración en la piel y la extensibilidad de la crema, mientras que las poliacrilamidas producen un efecto filmógeno y facilitan la permanencia del principio activo en la piel. Estudios preclínicos han mostrado una alto grado de actividad in vitro frente a especies de Candida, incluyendo C. tropicalis, dermatófitos y Malassezia furfur. En un estudio reciente, el eberconazol mostró una actividad in vitro superior al clotrimazol, el ketoconazol y el miconazol frente a 200 cepas de dermatófitos. El eberconazol ha mostrado actividad en pruebas in vivo: dermatofitosis, candidiasis y pitiriasis experimentales del cobayo. No presenta hipersensibilidad retardada, y no produce fotosensibilidad, efecto fototóxico ni absorción sistémica. Ha demostrado una eficacia superior que el clotrimazol en crema al 1% y equivalencia terapéutica con miconazol al 2% en el tratamiento de las micosis cutáneas producidas por dermatófitos, con una eficacia similar en el tratamiento de la candidiasis y la pitiriasis versicolor. Por todo ello, puede considerarse su uso en la práctica clínica habitual (AU)


Eberconazole is an imidazolic compound for topical application, with fungistatic and fungicidal activity at high doses, and a broad spectrum of action, characterized by a hydrophilic-lipophilic molecular structure favoring penetration and continuance in the skin. The galenic components of this topical azole favor and optimize the drug’s action in the skin, fatty acid esters facilitate penetration in the skin and make the cream easy to spread, while polyacrylamides produce an filmogenous effect and facilitate the continuance of the active principle in the skin. Preclinical studies have shown a high degree of activity in vitro against Candida spp., including Candida tropicalis, dermatophytes and Malassezia furfur. In a recent study, eberconazole showed an in vitro activity superior to that of clotrimazole, ketoconazole and miconazole against 200 strains of dermatophytes. Eberconazole has shown activity in in vitro tests: experimental dermatophytosis, candidiasis and dermatophytoses in guinea pigs. It does not produced delayed hypersensitivity, photosensitivity or phototoxic effects or systemic absorption. It has shown greater efficacy than clotrimazole 1% and therapeutic equivalence to miconazole 2% in the treatment of cutaneous mycoses produced by dermatophytes, and has similar efficacy in the treatment of candidiasis and pityriasis versicolor. In view of the above, eberconazole can be used in routine daily clinical practice (AU)

ABSTRACT

La leishmaniasis comprende una serie de cuadros clínicos producidos por protozoos del género Leishmania, y sus manifestaciones dependen principalmente de la respuesta inmune del huésped. Su incidencia está aumentando en la última década entre los pacientes con SIDA; sin embargo, la asociación de leishmaniasis mucocutánea y VIH no es frecuente. Describimos el caso de un paciente varón de 54 años infectado por el VIH que desarrolló un cuadro de edematización e infiltración de labio superior y ulceración del labio inferior con afectación de ambas comisuras bucales y que tras estudio histológico fue diagnosticado de leishmaniasis mucocutánea. Se instauró tratamiento con antimoniales pentavalentes respondiendo de manera espectacular (AU)
