Prurigo nodularis is a chronic condition characterized by a papulonodular pruriginous eruption of unknown aetiology. This condition is a difficult disease to treat and causes frustration to both the patient and the treating doctor. A variety of systemic conditions have been reported to be associated with prurigo nodularis. ⋯ Other topical treatments such as topical vitamin D3, and topical capsaicin have also been reported to be effective. Oral treatments such as cyclosporin and thalidomide have been shown to improve both appearance of the skin and pruritus. We review the clinical features, associations, pathology, pathogenesis and treatment of prurigo nodularis.

A 7-year-old girl presented with itching and greyish-white sleeve-like structures in her hair. After ruling out other possible causes for the symptoms, such as nits and dandruff, it was determined that the patient was affected by hair casts. ⋯ Scanning electron microscopy combined with electron dispersive X-ray analysis (X-ray microanalysis) of the hair casts showed the chemical nature of the structures. Some elements present in the composition of the ingredients of the deodorant spray, such as aluminium, chlorine, silicon, magnesium and carbon, were also present in this uncommon type of hair casts.

From January 2001 to January 2002, Broken Hill, New South Wales, served as a trial site for teledermatology as one method of access to dermatologists. Fourteen participating general practitioners referred 46 patients making up 48 teledermatology cases. The mean diagnostic agreement between general practitioners and dermatologists was 35% and 50% for primary and differential diagnoses, respectively. ⋯ In this project, high patient and general practitioner acceptability and positive medical outcomes confirm the value of rural teledermatology. However, this project also revealed unexpected barriers and pitfalls in the effective operation of rural teledermatology. Lack of education of participants, inertia among potential users and patient inconvenience are issues that may adversely affect the effective implementation of rural teledermatology.

Case ReportsIntermittent oral cyclosporin for recurrent herpes simplex-associated erythema multiforme.
Recurrent erythema multiforme is one of three distinct clinical subtypes of erythema multiforme. We present a 42-year-old man with a 10-year history of recurrent herpes simplex virus-induced erythema multiforme. Our patient was debilitated by the frequency of his attacks and the associated pain, for which he often required leave from work. ⋯ Oral cyclosporin rapidly reduced his symptoms and led to rapid resolution of his erythema multiforme, provided the cyclosporin was commenced on day 1 or 2 of the erythema multiforme episode. Consequently, his quality of life has dramatically improved. We recommend the use of intermittent oral cyclosporin for recurrent, debilitating episodes of erythema multiforme.
