A 75-year-old man with a short history of cutaneous lesions of multicentric reticulohistiocytosis, preceded by a few months of a symmetrical polyarthritis is described. Within 5 months of onset of symptoms, he developed congestive cardiac failure secondary to pericardial involvement by the disease and succumbed despite therapy with cyclophosphamide and methylprednisolone. Post-mortem revealed the true extent of the disease, with nodules seen in the epiglottis and aryepiglottic folds, duodenal mesentery, pleura, pericardium and myocardium. Although the hallmarks of the disease are the papulonodular skin lesions, together with a severe, sometimes mutilating polyarthropathy, its widespread systemic nature is not often appreciated. We review five other cases in the literature with pericardial involvement and discuss aids to earlier diagnosis by synovial fluid cytology; gallium scanning is discussed as a potentially useful means of detecting the extent of systemic involvement in multicentric reticulohistiocytosis.

Introduction: This study evaluated the knowledge, attitudes and practices of Southeast Asian dermatologists in the management of atopic dermatitis (AD). Materials and Methods: A questionnaire survey of 255 dermatologists in Indonesia, Malaysia, the Philippines, Singapore, Thailand and Vietnam. Results: Familiarity with diagnostic criteria varied considerably. The usage of moisturisers by the respondents from Vietnam and Indonesia was significantly less frequent than the other countries. Most respondents (91% to 100%) used topical corticosteroids in children with mild-to-moderately severe dermatitis. Some respondents in the Philippines (17% to 19%) and Vietnam (11% to 25%) only used topical corticosteroids for severe disease. For infected eczema, most respondents would prescribe systemic antibiotics for mild-to-moderate infection. A minority in the Philippines (14%) and Vietnam (11%) did so only for severe infection. The top 4 systemic antibiotics prescribed most frequently were: erythromycin, cloxacillin, cephalosporin and amoxicillin/clavulanic acid. In Indonesia, a large proportion of the respondents (47%) prescribed amoxicillin most frequently. The majority of respondents (60% to 100%) prescribed both sedating and non-sedating oral antihistamines. Most respondents used oral corticosteroids to treat severe AD. Some in Malaysia, Singapore and Vietnam used cyclosporin (7% to 58%), azathioprine (5% to 31%) and methotrexate (5% to 14%). With the exception of those in Singapore, the majority of respondents (71% to 97%) did not use phototherapy. Conclusion: Familiarity with diagnostic criteria, the early and judicious use of moisturisers and topical corticosteroids, as well as the treatment of Staphylococcus aureus superinfection with penicillinase-stable antibiotics should be emphasised in this region.
