Dermatomyositis.

Dermatomyositis is a disease that has a characteristic skin eruption that may occur with or without a proximal myopathy. The disease with cutaneous features only is classified as amyopathic dermatomyositis. The origin is unknown, but autoimmune factors are believed to play an important role. Autoantibodies are found in most patients and some have myositis-specific antibodies. Systemic changes may occur and there appears to be a relationship to internal malignancy, particularly in older patients. Juvenile disease has an associated vasculopathy. Treatment includes systemic corticosteroids and other immunosuppressive agents. The cutaneous changes may be difficult to treat.

Vamos a Traducir los MRV (let's translate the VRM): linguistic and cultural inferences drawn from translating a verbal coding system from English into Spanish.

Translating a verbal coding system from one language to another can yield unexpected insights into the process of communication in different cultures. This paper describes the problems and understandings we encountered as we translated a verbal response modes (VRM) taxonomy from English into Spanish. Standard translations of text (e.g., psychotherapeutic dialogue) systematically change the form of certain expressions, so supposedly equivalent expressions had different VRM codings in the two languages. Prominent examples of English forms whose translation had different codes in Spanish included tags, question forms, and "let's" expressions. Insofar as participants use such forms to convey nuances of their relationship, standard translations of counseling or psychotherapy sessions or other conversations may systematically misrepresent the relationship between the participants. The differences revealed in translating the VRM system point to subtle but important differences in the degrees of verbal directiveness and inclusion in English versus Spanish, which converge with other observations of differences in individualism and collectivism between Anglo and Hispanic cultures.

Human cutaneous allergic late-phase response is inhibited by soluble IL-1 receptor.

The late-phase allergic reaction (LPR) occurs 4 to 8 h after allergen exposure and probably causes the symptoms of chronic allergic disease. To determine the effects of soluble IL-1 receptor on the cutaneous LPR, we performed a prospective, randomized, double-blind, placebo-controlled study on 15 allergic subjects. Intradermal injections of allergen were placed on subjects' forearms, followed by immediate subcutaneous injections at the same site of either 1, 10, 25, 50, or 100 micrograms of rhu IL-1R to three subjects in each dosage group. Placebo was given to matched allergen-injected sites on the contralateral arm. Erythema, induration, and itching were recorded for each site. Sites were biopsied at 8 h for immunohistologic evaluations. Rhu IL-1R significantly reduced the clinical reaction at all concentrations. At 1 and 10 micrograms, measurements of LPR were significantly less (p < 0.05) than at placebo sites at several time points from 2 to 8 h. At higher concentrations, LPR was suppressed at rhu IL-1R and placebo sites, suggesting a systemic effect of rhu IL-1R. Histologic evaluation and indirect immunofluorescence for eosinophil granule major basic protein, neutrophil elastase, and mast cell tryptase showed no statistical differences between rhu IL-1R and placebo sites or among doses. IL-1 plays an important role in the generation of allergic LPR. While microgram quantities of rhu IL-1R inhibited the clinical signs and symptoms of LPR, its effects on the allergic inflammatory infiltrate are yet to be defined. In this short term trial, rhu IL-1R was neither immunogenic nor toxic.

Dermatomyositis as a systemic disease.

Dermatomyositis is a classic example of a disease that has both cutaneous and systemic manifestations. The skin and muscle disease are described as well as the possible systemic manifestations including overlap syndromes, joint symptoms, pulmonary disease, and other internal organ involvement. The association with pregnancy is also discussed.

The aging face. Why changes occur, how to correct them.

Most changes that occur in the aging face are related to gravity working on skin that is becoming progressively thinner, drier, and less elastic. Exposure to sunlight hastens these changes, and protection from the sun is the only proved way to delay them. Dermabrasion, chemabrasion, and collagen implant (Zyderm) injection are safe and effective nonsurgical procedures that can improve the appearance of the aging face. Plastic surgical procedures to remove excess skin at the upper eyelids, raise the eyebrows, tighten the lower lids, and elevate the nasal tip can provide functional as well as cosmetic improvement.

Multicenter clinical evaluation of ketoconazole in the treatment of cutaneous fungal infections.

An open, multicenter study was conducted to evaluate the efficacy and adverse effects of ketoconazole in patients with cutaneous fungal infections seen in typical dermatology practices. One hundred twelve American investigators entered 954 patients into this trial. Responses based on clinical and mycologic assessments were available on 672 patients. Mycologic evaluations were conducted using pre- and post-therapy wet mounts in potassium hydroxide. Eighty percent of these patients were mycologically clear and clinically rated as either excellent (cured) or marked improvement. Adverse effects were mild to moderate in severity and only rarely caused therapy to be interrupted. Gastrointestinal effects were the most frequently reported complaints.

Secondary cutaneous mucinosis with systemic lupus erythematosus. A case presentation and review of the literature.

A patient had papular and nodular cutaneous deposits of mucin and cutaneous and systemic manifestations of lupus erythematosus (LE). Since many of the mucinous deposits occurred at sites that were clinically free of skin lesions of LE, we considered initially that the patient had both LE and papular mucinosis. However, after a review of the English literature and further study of the patient, it seemed more likely that the papular and nodular deposits of mucin were secondary to LE and not a previously unreported simultaneous occurrence of the two diseases in the same patient. To our knowledge, this is the third case report of a patient with papular and nodular cutaneous mucinosis secondary to LE. In addition to the case report, this article is concerned with a discussion of cutaneous mucinosis in LE and other "collagen vascular" diseases.

Acne vulgaris: recent advances in pathogenesis and treatment.

Hormonal factors, particularly androgens, appear to be important in the pathogenesis of acne vulgaris. The sebaceous glands in acne are more sensitive to normal blood levels of androgens, and are stimulated to produce more sebum. Corynebacterium acnes in the sebaceous follicles act on triglycerides in the sebum to form free fatty acids which might alter the process of keratinization in the follicular canal. A microcomedo is formed which can progress to the clinical lesions of acne. Sebum and its components may also be inflammatory if released into the skin. There are, however, still a number of unanswered questions relating to acne pathogenesis. Currently, therapy of acne vulgaris revolves around topical benzoyl peroxide and retinoic acid and systemic tetracyclines. Benzoyl peroxide and tetracyclines are antibacterial while retinoic acid is comedolytic. Because of these different actions, combined therapy appears to be more effective (benzoyl peroxide and/or tetracyclines together with retinoic acid). Topical antibiotics show promise as new therapeutic agents.

Shortage of full-time faculty in dermatology.

A persistent shortage of full-time faculty exists in dermatology. Despite the addition of 124 new full-time faculty since 1971 through 1972, 136 training programs in 1974 through 1975 were actively seeking 88 new full-time faculty and believed they needed 243. With a net gain of 30 new faculty a year, it will take 2.93 years to add 88 new faculty that are being actively sought and 5.16 years to add 155 more that are urgently needed. During this eight years, demand for new faculty will increase, so that figures of need may remain essentially unchanged in 1982 through 1983 and between 1971 through 1972 and 1974 through 1975. Expertise that was most needed was in immunology, electron microscopy, histopathology, microbiology, and biochemistry; many accept faculty in any area or with no special training. Measures should be taken to attract and retain more dermatologists in full-time academic positions.
