Risk factors in pediatric dermatologic surgery.

BACKGROUND: Specific risk factors for complications in pediatric dermatologic surgery have not been studied in previous reports. OBJECTIVES: Analyze complications of a cohort of children for anesthetic and surgical complications and determine specific risk factors for surgical complications. METHODS: Retrospective collection of data from 210 consecutive children having operations over 6 years. Bivariate and logistic regression statistical analysis of complications and risk factors was conducted for single step interventions. RESULTS: General anesthesia complications were observed in 10.07 percent of the cases: Agitation and stridor were the most common anesthetic complications. Surgical complications were observed in 22.63 percent of the cases. Scar stretching followed by infection were the most prevalent complications. Complication rates, both anesthetic (9.09%) and surgical (13.63%) of multiple step interventions were similar to single step surgery. Intradermal absorbable suture in upper closure (p=0.028) and in limb (p=0.014) location were independently associated with complications. CONCLUSION: General anesthesia is safe in pediatric dermatology in the hands of experienced pediatric anesthetists. The most frequent surgical complication was scar stretching. Limb location and use of absorbable continuous intradermal suture in the upper closures should be taken into account as possible risk factors when informing parents and performing these procedures.

Petechial exanthem in "bathing trunk" distribution caused by parvovirus B19 infection.

We report a 13-year-old boy with a petechial rash on the genital area, in which primary infection by Parvovirus B19 was demonstrated by seroconversion. To our knowledge this is the first instance of an exanthem arising from Parvovirus B19 with an exclusive genital distribution without typical acral involvement.

Tratamiento del prúrigo actínico con tacrolimus al 0.1% / Treatment of actinic prurigo with tacrolimus

El prúrigo actínico, previamente denominado “prúrigo estival de Hutchinson”, es una fotodermatosis que afecta típicamente a nativos americanos y que se inicia en la infancia. Se caracteriza por lesiones papulosas muy pruriginosas, frecuentemente excoriadas y eccematizadas, localizada en piel fotoexpuesta. Generalmente se acompaña de conjuntivitis y queilitis. Tiende a mejorar con la edad, pudiendo desaparecer en la fase adulta. Los tratamientos habituales incluyen las medidas preventivas y los tratamientos sintomáticos, con antihistamínicos orales, emolientes y corticoides tópicos. Presentamos un caso de prúrigo actínico tratado con pomada de tacrolimus al 0,1% con una respuesta muy buena y rápida. La utilización de la pomada de tacrolimus al 0,1% es una alternativa segura y eficaz en el tratamiento del prúrigo actínico

Actinic prurigo, previously designated Hutchinson’s summer prurigo, is a photodermatosis that typically affects American natives. It usually begins during chidhood and tends improve during adolescence and adult life. The eruption consists of pruritic papules, frequently excoriated and eccematized, in sun-exposed skin. Cheilitis is common, as in conjunctivitis. Treatment includes the avoidance of sunlight and the use of sunscreens and protective clothing. Emollients, topical steroid and antihistamines help to control symptoms. We report a case of actinic prurigo who presente a dramatic response with tacrolimus ointment. Thus, tacrolimus ointment is a safe and effective treatment in actinic prurigo
