A 39‐year‐old woman showed nonsustained polymorphic ventricular tachycardia (PVT) during light physical activity. Cardiac multidetector row computed tomography demonstrated false tendons, one of which proved to be the focus triggering premature ventricular contraction (PVC) in electrophysiological studies. The triggered PVC arose during the diastolic period, which might have caused tension in the false tendon. Radiofrequency catheter ablation targeting the triggered PVC by pace mapping was performed and proved partially effective against PVT. (PACE 2012;35:e341–e344) 相似文献

Dermatofibrosarcoma protuberans (DFSP) is a slow growing, locally invasive tumour whose differentiation from other fibrohistiocytic tumours sometimes poses serious diagnostic problems. We investigated CD34 expression immunohistologically in various fibrohistiocytic tumours including dermatofibroma, DFSP, malignant fibrous histiocytoma (MFH), infantile myofibromatosis, fibrosarcoma, hypertrophic scar and keloid. Among these, DFSP was unique in that tumour cells themselves expressed CD34, whereas in other tumours. CD34 expression was observed only on vascular endothelial cells amongst the tumour cells. Until now, there have been no reports of useful immunohistological markers for DFSP. CD34 expression by the tumour cells can be an extremely useful marker in establishing a definitive diagnosis of DFSP. 相似文献

A 13 year old girl with carpopedal spasm is presented. Investigation values showed hypomagnesemia and hypokalemia. Her younger brother and sister demonstrated the same biochemical abnormalities without any symptoms. Their urinary excretion of magnesium and potassium were inappropriately high compared with their serum levels. Treatment with oral magnesium sulfate failed to correct the abnormalities, but serum levels of magnesium and potassium were just below the lower limits. This familial disease may represent congenital renal wasting of magnesium and potassium. 相似文献

An 8 year old girl was admitted to hospital complaining of arthralgia in a few large joints. According to the clinical course and serological tests, a diagnosis of a polyarticular type of juvenile rheumatoid arthritis was made. About 6 weeks after the onset, scoliosis was observed. The curvature regressed spontaneously over the following 6 months. Generally, scoliosis associated with juvenile rheumatoid arthritis has been noted a few years after the onset. A transient scoliosis in the early phase of this disease is rare. 相似文献
