Femoral artery compression device for outpatient angiography

To avoid late bleeding from the femoral artery puncture site after outpatient femoral angiography, a compression device was designed to exert continuous pressure over the groin, even when the patient is upright. It has been successfully used in more than 2,000 arterial catheter procedures. The device can also help prevent bleeding in patients who are at increased risk because of hypertension or anticoagulant therapy.     

The role of chromosomal translocation (15;19) in the carcinoma of the upper aerodigestive tract in children

OBJECTIVE: To further evaluate the role of chromosomal translocation (15;19) in the presentation of the carcinoma (CA) of the upper aerodigestive tract. STUDY DESIGN AND SETTING: A retrospective study at a tertiary care pediatric medical center. RESULTS: Seven patients with a mean age of 12 years presented with CA of nasopharynx (N = 2), sinonasal region (N = I), parotid gland (N = 2), or larynx (N = 2). Treatments included combinations of surgery (N = 5), chemotherapy (N = 5), and radiation therapy (N = 4). One patient with sinonasal CA and one patient with laryngeal CA had chromosomal translocation (15;19); these patients both died of their disease with a mean survival of 6 months. The 5 patients without translocation (15;19) responded well to treatment and are disease-free with a mean follow-up of 47 months. CONCLUSION: The preliminary results appear to indicate poor prognosis associated with the presentation of chromosomal translocation (15;19) despite aggressive multi-modality treatment. Further investigation is needed to better understand the cause and relationship of the translocation (15;19) and aggressive behavior of these tumors.
