Persistent light reactions. A review with opinions.

A review of persistent light reactions in South Australia is related to the European, American and Australian experience of photosensitivity and compositae dermatitis. It is argued that contact and drug photosensitising chemicals are retained in the dermis and slowly metabolised, and that actinic reticuloid will clear if all potential photosensitisers are avoided.

Environmental dermatitis: changing patterns.

Patch tests in 1000 cases of contact allergic dermatitis observed between 1972 and 1978 are recorded in detail, and compared in general with patch tests in a previously recorded 1000 cases of contact allergic dermatitis between 1964 adn 1972. The routine use, since 1974, of patch tests as advised by the International Contact Dermatitis Research Group has increased the detection of dermatitis caused by nickel, paraphenylene-diamine and related dyes, formaldehyde and perfumes (balsam of Peru), which indicates that aimed patch tests alone may be inadequate. The number of cases of dermatitis caused by antifungal agents and topical antihistamines decreased after Commonwealth and State legislation prohibiting their use was passed.

Erythroderma, an unusual manifestation of B cell lymphoma.

A case is described in which the initial manifestation of a malignant lymphoma was an erythematous skin rash over the face, scalp and trunk. Immunological surface marker analysis showed the malignant cells to be of B lymphocyte origin with a homogeneous secretion of IgM-K. Repeated skin and lymph node biopsies and finally post mortem documented the progression of the lymphoma from that of a mixed lymphocytic-histiocytic type with a nodular pattern of growth to a diffuse histiocytic lymphoma with frequently bizarre cells. The theory of ecotaxis or homing of lymphocytes to the skin and other non-lymphoid organs of the body is discussed in an attempt to explain the occurrence of cutaneous involvement as a primary manifestation of lymphoma.

Phototoxic blisters from high frusemide dosage.

Blistering of exposed areas has appeared in patients suffering from chronic renal failure treated with high doses of frusemide. The blistering, which resembles that occurring in nalidixic acid phototoxicity and in porphyria cutanea tarda, is considered phototoxic in nature.

Contact dermatitis from radiata pine.

Sawdust from radiata pine trees which are grown extensively throughout South Australia causes various forms of contact dermatitis. The various forms are described in nine cases which illustrate that the early diagnosis of industrial dermatitis is necessary to prevent the condition from becoming chronic. A chance association between colophony in radiata pine sawdust and colophony in adhesive plaster, which caused contact dermatitis when used in patch testing, led to the discovery of these cases.
