Unusual manifestations of primary cutaneous amyloidosis in association with Raynaud's phenomenon and livedo reticularis.

A patient with unusual manifestations of primary cutaneous amyloidosis, including macules, papules, oedematous plaques and urticarial lesions is described. Raynaud's phenomenon and livedo reticularis were an associated finding. During the acute phase, single doses of systemic corticosteroids resulted in an impressive, long-lasting improvement in cutaneous manifestations.

Development of anthralin short-contact therapy in psoriasis: survey of published clinical trials.

In a survey of clinical trials concerning the efficacy of short-contact therapy with anthralin in psoriasis vulgaris, focusing principally on methodologic issues, twenty-four papers published between January 1982 and December 1989, in English, French, and Italian, were selected. Nine of 24 papers reported on more than one trial, giving a total of 37 clinical trials to be evaluated. A great heterogeneity was evident in many aspects of the design and conduct of these trials, making pooling of results impossible. Most trials suffered from flaws in general methodologic aspects such as randomization and blinding. Limitations in general applicability of results were discussed with reference to the popular use of self-control design and selection of composite indexes (e.g., PASI) as an outcome variable. Published trials are not a reliable guide to clinical decisions concerning short-contact therapy, and some methodologic observations we made could be of general interest in designing clinical trials of psoriasis.

Eyelid dermatitis: an evaluation of 150 patients.

This study was performed to evaluate eyelid dermatitis in a group of patients of our Allergy Unit between January 1990 and April 1991. Among the 1158 patients seen during this period, 150 had eyelid dermatitis: 135 females and 15 males, with a mean age of 35 years. Of the 150 patients with eyelid dermatitis, 54 had eczema localized to the eyelids only, 49 to the eyelids and face, 19 to the eyelids and hands, and 28 to the eyelids and other sites. 98 patients (65.3%) were diagnosed as having allergic contact dermatitis, 25 (16.6%) irritant contact dermatitis, 21 (14%) atopic dermatitis, and 6 (4%) seborrhoeic dermatitis. Patch test reactions to nickel sulphate, Kathon CG and fragrance-mix occurred more frequently in patients with eyelid dermatitis than in those without.

Alopecia areata and interleukin-2 receptor.

Interleukin-2 (IL-2) is a lymphokine produced by activated T cells and its receptor (IL-2R) is expressed on T cells; one of the IL-2R components can be measured as a soluble serum protein (sIL-2R). Levels of sIL-2R were measured as a sign of T cell activation in serum of 12 patients suffering from alopecia areata (totalis or universalis) and in a group of healthy control subjects. An enzyme-linked immunosorbent assay was used to determine the levels of sIL-2R in blood samples drawn during both the active and resting phase of the disease. In patients with alopecia areata in active phase the sIL-2R concentrations were significantly higher than in stable phase and in controls. The biologic role of sIL-2R is still unknown, but one could speculate that T lymphocyte activation with subsequent secretion of IL-2 and IL-2R expression may contribute to the immune inflammatory mechanism of alopecia areata.

Segmental lentiginosis with "jentigo" histologic pattern.

We report a case of segmental lentiginosis (unilateral lentiginosis), that is, asymmetric distribution of lentigines on one side of the body, in a 23-year-old woman. Lesions involved the right side of the face and the cervical region, mostly within the area of division of the trigeminal nerve. Histologic examination disclosed a lentiginous pattern as well as some nests of melanocytes at the dermal-epidermal junction (so-called jentigo pattern). Similar cases have been described in the literature under the term "zosteriform lentiginous nevus," which in our opinion makes for confusion since the same term has also been used to describe cases that fit the diagnostic criteria for speckled lentiginous nevus (nevus spilus).

Risk factors for HIV infection in adults attending sexually transmitted disease clinics in Italy.

We assessed prevalence and risk factors for human immunodeficiency virus (HIV) infection in 637 patients (506 men, 131 women; median age 30 years, range 17-64) attending between September 1988 and July 1989 for the first time two sexually transmitted disease (STD) clinics in Northern Italy, for suspected or STD treatment. A total of 44 subjects (6.9%, 95% confidence interval, (Cl): 4.9-8.9) were seropositive for HIV antibodies. The prevalence of HIV infection decreased with age, from 9% in patients aged 24 years or less to 3% in those aged 45 years or more (chi 21 trend 4.97, p less than 0.05). Women tended to have a lower prevalence of infection than men (5.3% versus 7.3%) but this was not statistically significant. Compared with men reporting no homosexual intercourse, HIV infection risk was about 50% higher in those reporting bisexual intercourse (age- and sex-adjusted odds ratio (OR) 1.5,95% Cl: 0.6-3.6) and about fourfold in those reporting only homosexual intercourse (OR 3.8, 95% Cl: 1.7-8.5). No clear trend in risk was observed with number of sexual partners both in men and in women. Intravenous drug users had an increased risk of HIV infection; compared with non-users, the OR was 5.6 (95% Cl: 3.0-10.5) in users, and the point estimates increased with frequency of use, from 3.3 (95% Cl: 0.8-11.5) in occasional users to 6.4 (95% Cl: 3.2-12.8) in regular users. The risk of HIV infection was 2.2 (95% Cl: 1.1-4.3) in patients reporting a history of STD, and 1.6 (95% Cl: 0.8-3.3) in those reporting syphilis.(ABSTRACT TRUNCATED AT 250 WORDS)
