Ipsilateral arcuate foramen and high-riding vertebral artery: implication on C1-C2 instrumentation.

Background Context: Several methods for C1-C2 stabilization have been described in the literature. These include C1-C2 transarticular and C1 lateral mass screws. In patients with aberrant anatomy such as a high-riding vertebral artery (VA) or the presence of an arcuate foramen at C1, there exists a higher risk of VA injury.

Activity of continuous infusion plus pulse interleukin-2 with famotidine in patients with metastatic kidney cancer or melanoma previously treated with interleukin-2.

Lymphokine-activated killer (LAK) cells generated by high-dose continuous infusion interleukin-2 (IL-2) are able to nonspecifically lyse melanoma and kidney cancer cells. In vitro famotidine enhances cytotoxicity of LAK against tumor cells, possibly by increasing IL-2 uptake at the IL-2 receptor on lymphocytes. Outpatient IL-2 regimens typically have response rates of 15% or less, with most patients eventually experiencing progressive disease.

The impact of osteoporosis on patients with maxillofacial trauma.

Background: Although maxillofacial injuries in the elderly population frequently result from falls and motor vehicle crashes, the association between osteoporosis and fractures of the maxillofacial region remains poorly defined.

Objective: To evaluate the relationship between osteoporosis and maxillofacial trauma in the elderly. DESIGN, SETTING, AND MAIN OUTCOME MEASURES: A retrospective review of 59 patients 60 years or older treated for maxillofacial fractures at a trauma center between 1989 and 2000 was performed.
