Review Case Reports
Fire-eater's lung: seventeen cases and a review of the literature.

We analyzed a series of 112 consecutive cases of left atrial myxoma diagnosed in a single French hospital (72 women and 40 men; age range, 5-84 yr) over 40 years, from 1959 to 1998. Symptoms of mitral valve obstruction, the first arm of the classic triad of myxoma presentation, were present in 75 patients (67%), with mostly cardiac failure or malaise. Symptoms of embolism, the second frequent presentation in the classic triad, were observed in 33 cases (29%) with 1 or several locations, essentially cerebral emboli with stroke. ⋯ Myxomas in patients presenting with embolism have a friable surface; those in patients with cardiac symptoms, pseudo-mitral auscultation signs, tumor plop, and electrocardiogram or radiologic signs of left atrium hypertrophy and dilatation are significantly the larger tumors. The long-term prognosis is excellent, and only 4 deaths occurred among our 112 cases over a median follow-up of 3 years. The recurrence rate is low (5%), but long-term follow-up and serial echocardiography are advisable especially for young patients.

Review Comparative Study
Familial lupus erythematosus. Clinical and immunologic features of 125 multiplex families.
Evidence for a genetic susceptibility to systemic lupus erythematosus (SLE) in humans is based on the high concordance rate observed in identical twins and on the relatively high incidence of familial cases. Although recent genetic studies have lead to significant advances in the identification of new susceptibility genes in SLE, no large clinico-pathologic study of familial SLE has been reported to date. In the present study, we describe the main clinical and immunologic features of 125 lupus multiplex families including at least 2 cases of SLE and/or discoid lupus erythematosus (DLE), recruited through a French national survey starting in July 1997. ⋯ No obvious mode of inheritance could be suspected in most of the remainder. Among French Caucasians, sex ratio, mean age at onset, and clinical and biologic SLE-related manifestations were not significantly different in multiplex compared with sporadic SLE cases. The analysis of these 125 multiplex families suggests a genetic heterogeneity that should be considered for ongoing genomic screening.
