Fatal myocardial necrosis caused by Staphylococcus lugdunensis and cytomegalovirus in a patient with scleroderma.

A 42-year-old woman developed a rapidly progressing fatal heart failure. At the autopsy extensive necrosis of the myocardium was seen, with an almost complete absence of inflammatory cells and the presence of bacterial structures identified as Staphylococcus lugdunensis by PCR. In addition, the cytomegalovirus genome was found to be located inside the cardiomyocytes.

Erythema migrans--influence of posture. Case report.

Despite widespread awareness of the most classical clinical presentation with central clearing of erythema migrans, a pathognomonic sign of infection with Borrelia burgdorferi, diagnosis of other forms of erythema migrans remains more difficult. We describe a case of a patient with secondary lesions of erythema migrans that within three months formed a complicated pattern and affected at last nearly the entire lower limb of the patient. In addition, the erythema appeared to be posture-dependent in the way that the lesion was with central clearing in the supine and with homogeneous appearance in the upright position.
