Systemic lupus erythematosus presenting with 'rheumatoid nodules'.

A patient with systemic lupus erythematosus who presented with subcutaneous nodules over the flexor aspect of the fingers in association with arthritis and Raynaud's phenomenon is described. Histopathological examination of the nodules showed appearances consistent with rheumatoid nodules. Further investigations revealed leucopenia and circulating anti-nuclear antibody but negative rheumatoid factor. Immunofluorescence studies of normal non-light exposed skin showed the presence of IgM deposits at the dermo-epidermal junction consistent with systemic lupus erythematosus. The nodules almost disappeared following treatment with hydroxychloroquine. Rheumatoid-like nodules have been reported in systemic lupus erythematosus, although rarely. However, the distribution of the nodules and the patient's clinical course differ from the few cases previously reported in the literature.

Reticulate pigmented anomaly of the flexures. Dowing Degos disease, a new genodermatosis.

Acquired reticulate pigmentation of the flexures developed in ten patients. Additional features in some cases were pitted scars near the angles of the mouth and scattered dark comedone-like lesions on the neck (dark dot follicles). The disease affects both sexes, usually develops in early adult life, and is slowly progressive. The abnormality is characterized by pigmented filiform epidermal downgrowths closely resembling an adenoid seborrheic wart, but similar proliferations also develop around the variably dilated pilosebaceous follicles. The occurence of the anomaly in siblings and in mother and daughter in two families suggests the condition in a new genodermatosis. Reticulate pigmented anomaly of the flexures bears a spurious clinical resemblance to acanthosis nigricans and, thus, the recognition of this new genodermatosis should spare patients undergoing unnecessary investigations to exclude visceral malignancy.

The relationship of transepidermal water loss to skin temperature in psoriasis and eczema.

Transepidermal water losses (TEWL) from psoriatic and eczematous skin were measured while skin temperature was varied between 29 degrees C and 37 degrees C. The relationship of TEWL to skin temperature in these diseases is different from that obtaining in normal skin. These differences are thought to be due to the altered filtration properties of diseased stratum corneum. Formulae were devised to allow TEWL rates in psoriasis and eczema to be expressed at a standard temperature for comparative purposes.

An evaluation of Na+, C1- and pH ion-specific electrodes in the study of the electrolyte contents of epidermal transudate and sweat.

Ion-specific electrode detectors have been used to measure electrolytes in various biological fluids, including sweat. As part of a study of skin barrier function, we have used such electrodes to detect the presence of sodium, chloride and hydrogen (pH) in the transepidermal water loss. This paper describes the effects of cellophane tape stripping (of human forearm epidermis in vivo) on surface electrolyte concentrations, in parallel with observations on transepidermal water loss and galvanic skin resistance.
