In a questionnaire study to assess psychological disabilities in 110 patients with port wine stains, 71 completed questionnaires were analysed. The questionnaire revealed a high level of psychological morbidity resulting from a feeling of stigmatization amongst these patients that was not apparent in casual social intercourse. In contrast, standard psychological screening tests for psychiatric illness, depression or anxiety revealed that these patients had similar or less evidence of morbidity than controls or other patient groups. It would appear that patients with port wine stains suffer a considerable degree of psychological morbidity which they suppress. This may be related to a need to hide their port wine stain.

The response of rosacea-associated erythema and telangiectasia to treatment with the pulsed tunable dye laser (PDL) was evaluated in 12 patients. Improvements in erythema, telangiectasia, flushing, the physician's and the patient's perception of overall severity, treatment tolerability, and the adverse side effects were examined. With the sole exception of the patient's assessment of overall severity we have found highly significant improvements in all other parameters evaluated, with excellent tolerance of treatment. We therefore conclude that the PDL is a safe and effective treatment for the erythemato-telangiectatic component of rosacea.

During the last 5 years, 640 patients had treatment to their port wine stains (PWS) with a flashlamp-pumped pulsed dye laser. One hundred and fifty-six patients have been discharged for varying reasons, of which 59 (38%) achieved excellent (at least 75%) lightening of their birthmark. Of the remaining patients, those who attended the clinic for the sixth and 12th time for treatment were also assessed to determine the degree of fading achieved in the port wine stain. Our findings confirm that flashlamp-pumped dye laser treatment is safe and effective for the treatment of PWS and that complications are rare. However, the degree of fading achieved is variable and often unpredictable. Fifty-two per cent of facial lesions of different colours achieved over 75% fading as against 18% of non-facial lesions. Sixty-four per cent of those over the age of 50 years had an excellent response whereas only 19% of those below the age of 5 years were able to achieve a similar result. The colour of the port wine stain was found to be of no prognostic value. A search for an accurate and non-invasive method to predict the outcome of flashlamp-pumped pulsed dye laser therapy for PWS is warranted.
