Oral pemphigus vulgaris: a review of the literature and a report on the management of 12 cases.

Twelve cases of oral pemphigus vulgaris are described to illustrate the long-term behavior of the disease and the treatment challenges it presents to the oral medicine practitioner. In addition, we review the literature on oral pemphigus vulgaris with respect to clinical history, signs and symptoms, management, and treatment outcome. Pemphigus vulgaris is a chronic vesiculobullous disease with a potentially fatal outcome. Mortality from pemphigus vulgaris before the development of effective therapies was as high as 90%. Today, with treatment, it is closer to 10%. Involvement of the oral mucosa is common and in most cases precede skin lesions; in our patients, the oral lesions preceded the development of extraoral disease in 75% of cases. Pemphigus vulgaris was more frequent among women (9:3), and there was a tendency for the severity and frequency of disease to decrease with time.

Risk of malignant transformation of congenital melanocytic nevi in blacks.

The risk of small congenital melanocytic nevi (CMN) developing into melanoma is not known, but is highly controversial. The frequency of small CMN is, paradoxically, slightly higher in some populations, such as blacks, who are at a lower risk of developing melanoma than whites. An estimate of the risk of malignant transformation of CMN in such a low-risk population could help in the management of congenital nevi in these patients and might also shed light on the inherent malignant risk of small CMN. We used a national population-based cancer registry, the Surveillance, Epidemiology, and End Results program (SEER), and the incidence of CMN in blacks taken from published newborn surveys to calculate a risk of malignant transformation. We calculated a maximum risk using a model based on a worst-case scenario, assuming that all melanomas on glabrous skin arise in CMN. We also calculated a modified risk based on the known historical association of nevi and melanomas in blacks, and estimates of the histologic association of the two. The cumulative maximum risk of malignant transformation in blacks to age 75 years was 1 in 164. It was strongly age dependent, with the majority occurring in persons over age 45. The estimated maximum risk before age 15 was less than 1 in 10,000 CMN, and in blacks age 15 to 35 less than 1 in 3700 CMN. The modified risk suggests that the worst-case scenario overestimates the risk by at least a factor of 12, making the actual risk in blacks up to age 75 approximately 1 in 2000.(ABSTRACT TRUNCATED AT 250 WORDS)

510-nm pigmented lesion dye laser. Its characteristics and clinical uses.

BACKGROUND: Benign pigmented lesions are of a cosmetic concern to many individuals. Numerous treatments exist, including several types of lasers. The Candela 510 nm pigmented lesion dye laser has recently been added to this armamentarium. It is designed specifically for the treatment of superficial pigmented lesions while significantly decreasing the risk of scarring and prolonged hypopigmentation. OBJECTIVES: To describe the characteristics of the Candela pigmented lesion dye laser and report on the therapeutic outcome of patients treated for actinic lentigines, café-au-lait macules, melasma and red tattoos by one of the authors (RCG). METHODS: The Candela 510 nm pigmented lesion dye laser was used to treat solar lentigines, café-au-lait macules, melasma and red tattoo. RESULTS: Excellent outcomes resulted on facial and hand lentigines (89% and 88% of patients had greater than 75% clearing, respectively), but often required more than one treatment. Lentigines located on the upper extremities and trunk improved less dramatically. Immediate greying occurred universally. Bruising was often noted. Treatment failures have been observed especially in treating lentigines located on the lower extremities. Café-au-lait macules responded inconsistently, with facial lesions giving the best results. Melasma responded poorly, often with hyperpigmentation. Three red tattoos cleared. Treatment failure may be related to inaccurate clinical assessment of pigment depth or regrowth of the lesion. Several cases are presented to demonstrate clinical and histologic effects of the laser. CONCLUSION: The Candela 510-nm pigmented lesion dye laser is an effective treatment for superficial pigmented lesions. Its associated morbidity is minimal.

Diet and atopic dermatitis.

Prevention or modification of the onset of atopic dermatitis has been difficult to document through prolonged breast feeding or delayed introduction of solid foods. Dietary management of established atopic dermatitis is not routinely indicated for the majority of patients. Dietary management of atopic dermatitis should not be continued indefinitely. Gradual reintroduction of the offending food(s) is often appropriate. The foods most commonly avoided in the management of atopic dermatitis are cow's milk, wheat, eggs, and nuts. Severe or prolonged dietary restrictions should not be instituted without full consideration of their impact on the patient's general health.
