There is more than one reason why dermatologists should listen to their patients. Audible signs of cutaneous disease range from the classic, early childhood hoarseness of lipoid proteinosis to a characteristic hoarseness due to syphilitic papules on the epiglottis and arytenoepiglottic folds.
"Nonrashes" range from pruritus that may signal an underlying systemic illness to delusional parasitosis associated with severe psychological disturbance. We report another kind of nonrash, the Koebner nonreaction or isomorphic nonresponse, that was manifested by the absence of a drug rash at the site of recently administered x-irradiation. We also present a compilation of a number of other nonrashes, such as the mitempfindungen (referred itch) and the prodrome of herpes zoster. The recognition of certain types of nonrashes may be lifesaving.

In order to elucidate the nature and distribution of the pigment responsible for the circumscribed blue-black cutaneous hyperpigmentation occurring after administration of minocycline hydrochloride, transmission electron microscopy and energy-dispersive electron x-ray microanalysis were performed on lesional skin. Ultrastructural observations demonstrated electron-dense iron-containing particles either incorporated into a variety of siderosomes, within dermal histiocytes, free within the cytoplasm, or, rarely, scattered among dermal collagen fibers. Electron x-ray microanalysis confirmed iron content present within these particles. Although siderosomal inclusions contained occasional melanosome complexes, the degree of deposition of electron-dense iron-containing particles in dermal histiocytes seemed to be primarily responsible for the blue-black discoloration of the skin. The present study is an investigation of the structure and composition of the pigment responsible for minocycline-related cutaneous hyperpigmentation.

OBJECTIVE: This study tests the hypothesis that stress reduction methods based on mindfulness meditation can positively influence the rate at which psoriasis clears in patients undergoing phototherapy or photochemotherapy treatment. METHODS: Thirty-seven patients with psoriasis about to undergo ultraviolet phototherapy (UVB) or photochemotherapy (PUVA) were randomly assigned to one of two conditions: a mindfulness meditation-based stress reduction intervention guided by audiotaped instructions during light treatments, or a control condition consisting of the light treatments alone with no taped instructions. Psoriasis status was assessed in three ways: direct inspection by unblinded clinic nurses; direct inspection by physicians blinded to the patient's study condition (tape or no-tape); and blinded physician evaluation of photographs of psoriasis lesions. Four sequential indicators of skin status were monitored during the study: a First Response Point, a Turning Point, a Halfway Point, and a Clearing Point. RESULTS: Cox-proportional hazards regression analysis showed that subjects in the tape groups reached the Halfway Point (p = .013) and the Clearing Point (p = .033) significantly more rapidly than those in the no-tape condition, for both UVB and PUVA treatments. CONCLUSIONS: A brief mindfulness meditation-based stress reduction intervention delivered by audiotape during ultraviolet light therapy can increase the rate of resolution of psoriatic lesions in patients with psoriasis.
