Auspitz sign is not sensitive or specific for psoriasis.

The Auspitz sign refers to the appearance of small bleeding points after successive layers of scale have been removed from the surface of psoriatic papules or plaques. In this study the Auspitz sign was present in only 41 of 234 patients with psoriasis. Furthermore, small bleeding points could be produced when scale was forcibly removed from several nonpsoriatic, scaling disorders, including Darier's disease and actinic keratoses. The frequent absence of the Auspitz sign in psoriasis indicates a lack of sensitivity, whereas its occurrence in other diseases indicates a lack of specificity.

Incarceration for excoriation.

A thirty-six-year-old man experienced acute, severe, generalized pruritus. His scratching was erroneously interpreted as lewd and indecent behavior. He was arrested. Results of the history and physical examination led to the diagnosis of fiberglass dermatitis, which prompted a dismissal of the charges. Although many societies have looked askance at persons with certain skin diseases (such as leprosy) and at scratching in public since at least biblical times, we are not aware of any prior reports of incarceration for excoriation.

Nonrashes. 6. Telepathic pruritus.

We report the case of a paranoid schizophrenic man who suffered from the delusion that two other men used mental telepathy to make him itch over a period of thirteen years. To our knowledge, this is the first report of "telepathic pruritus."

Nonrashes. 5. Atmoknesis: pruritus provoked by contact with air.

Atmoknesis, itching provoked by open exposure of the skin to air after undressing, is a common and distressing symptom. It occurs in many patients with psoriasis and atopic dermatitis, and in elderly patients with aquagenic pruritus. It also occurs in some patients with underlying systemic causes of generalized pruritus, such as hepatobiliary disease. It does not seem to be an important feature of certain other pruritic skin diseases such as dermatitis herpetiformis and bullous pemphigoid.

Phototherapy and photochemotherapy in dermatologic diseases.

Phototherapy and photochemotherapy have been shown to be effective treatments in a number of cutaneous disorders, but they are not without risk. PUVA has revolutionized the treatment of psoriasis and stimulated major improvements in the administration of UVB therapy. Successful treatment depends on careful patient selection and evaluation. Accurate dosimetry and close supervision are necessary to avoid complications. Regular and careful follow-up, both during and after therapy, can help to identify and treat long-term side effects such as non-melanoma skin cancers. In order to achieve the necessary balance between benefits and risks with these valuable forms of therapy, patients should be referred to dermatologists with special training.

Lack of association between skin tags and colon polyps in a primary care setting.

Cutaneous skin tags (acrochordons) have recently been proposed as markers for adenomatous polyps of the colon among symptomatic patients referred for colonoscopy. To ascertain the utility of skin tags as a predictor of colonic polyps in a primary care setting, 492 patients, with a mean age of 58 +/- 13.3 years (241 with signs or symptoms and 251 for screening), were evaluated for the presence of skin tags and then examined using a 60-cm fiberoptic sigmoidoscope by an examiner "blinded" to the skin findings. Among patients with skin tags, 23 (10.2%) of 226 had polyps, whereas among patients without skin tags, 20 (7.5%) of 266 had polyps. The predictive value of the presence of a skin tag was 10.2%. Contrary to studies done in more selected populations with a higher prevalence of adenomatous polyps, the results using a 60-cm flexible sigmoidoscope in a primary care population suggest that cutaneous skin tags are not a marker for adenomatous polyps of the colon.
