Fatal outcome of cervical myelopathy caused by fibrocartilaginous embolism. Rare cause of spinal vascular damage.

BACKGROUND AND PURPOSE: Fibrocartilaginous embolism is a rare cause of ischemic myelopathy. Authors report a case of a 39-year-old woman with progressive tetraparesis and severe autonomic dysfunction. Despite of the detailed examinations, the definite diagnosis was verified by autopsy. METHODS: The patient was admitted because of progressive pain and numbness of the upper extremities and tetraparesis. Hypotonic muscles of the lower extremities with mild tetraparesis were observed. Magnetic resonance imaging showed an intramedullary lesion at the level of the cervical V-VII vertebral. Patient's tetraparesis worsened gradually to plegia with urinary retention. Expansive, rapidly progressing multiple decubiti developed, which were resistant to therapy. In spite of the complex therapy, the patient died. RESULTS: No internal disease was found to explain the death by autopsy. Multiple subacute infarctions of the cervical myelon (involving the lateral columns as well) in the territory of the anterior spinal artery were verified by neuropathological examination. The occluded vessels were filled by a material containing cartilaginous cells, while signs of atherosclerosis or thrombosis were not present. CONCLUSION: Cartilaginous embolism of spinal arteries was diagnosed.

[Subacute cardiotoxicity caused by anthracycline therapy in children: can dexrazoxane prevent this effect?]. / Az antraciklinek kardiotoxikus hatásának kivédése gyermekekben.

OBJECTIVES: The use of anthracyclines are limited by their cardiotoxic side effects (first of all congestive cardiomyopathy). In this study we analyzed the anthracycline-induced cardiotoxicity and the possible preventive role of dexrazoxane in children. PATIENTS: 158 anthracycline-treated long-term survivors could be analyzed. Sixty-one children received dexrazoxane (group D) and 97 patients received anthracyclines only (group C). METHODS: Cardiac ultrasound examinations (ECHO) and electrocardiograms (ECG) were performed regularly from the beginning of chemotherapy and yearly thereafter. Shortening fraction (FS) was used as indicator of the ventricular function. RESULTS: The incidence of reduced left ventricular function (FS) was 13.4% in C, and 8.2% in D (p=ns). Two years after completion of the chemotherapy FS was reduced in 13.7% in C and 0% in D, respectively (p=0.056), and 5 years after therapy in 11.0% in C and 2.4% in D, respectively (P=0.034). Left chamber wall diameter was abnormal in systole in 6% in C and 2% in D, in diastole in 11% in C and 7% in D (p=ns) after 3 years of follow-up. CONCLUSION: Anthracycline-induced subacute cardiotoxicity can be significantly diminished by the concomitant use of dexrazoxane. For the final conclusions longer follow-up is necessary.
