[Subjective perception of pain in local dermatological surgery].

Introduction: Pain is difficult to measure, as it has a significant subjective component. This symptom, and in particular its psycho-emotional component (fear prior to the operation and a feeling of release afterwards), has not been studied extensively. We decided to quantitatively evaluate its perception in local surgery, in relation to different moments during the operation and using the application of a topical anesthetic cream as an external variable.

Rosacea-like demodicidosis in an immunocompromised child.

Demodex folliculorum is a saprophytic mite of the human pilosebaceous unit. It is rarely found in children. It has been implicated in the development of follicular pityriasis, rosacea-like demodicidosis, pustular folliculitis, blepharitis, and granulomatous rosacea.

Detection of hepatitis C virus RNA and core protein in keratinocytes from patients with cutaneous lichen planus and chronic hepatitis C.

Cutaneous lichen planus has been associated in patients with chronic hepatitis C virus infection. It is still unknown whether hepatitis C virus infects keratinocytes of lichen planus lesions. In this report we have analyzed the presence of genomic and anti-genomic hepatitis C virus RNA in skin biopsies from 26 patients with chronic hepatitis C and healthy skin and from 24 patients with cutaneous lichen planus (five with and 19 without hepatitis C virus infection) by in situ hybridization.
