In this issue of the American Journal of Neuroradiology (page 475), Oppenheim et al document an extensive experience with linear accelerator radiosurgery for 197 patients over a 4-year period (January 1990 to December 1993). Of the 197 patients treated, 138 had what was defined as an ‘‘early’’ angiographic follow-up 6–18 months after treatment. The authors’ stated aim was to determine if an ear...

This paper is concerned with noun incorporation (NI) in Chukchi, a Kamchatkan language spoken in Siberia. The data discussed are taken from two papers on this subject, namely Polinsky (1990) and Spencer (1995). This amount of data is of course extremely restricted, but I attempt to give an insight into the phenomenon and its theoretical solution rather than discuss it thoroughly on the basis of...

The topic of this paper is a kind of morphological structure that looks as if it might be formed within the syntax: Noun Incorporation. This is a feature of a wide range of languages, including (in its purest form) Mohawk, Chuckchee, Southern Tiwa, Classical Nahuatl, and many others; and it has attracted attention for quite some time. Adopting a classical formulation, Noun Incorporation is a co...

OBJECTIVE The purpose of this study was to examine the efficacy and toxicity of treating small arteriovenous malformations (AVMs) (≤3 cm in diameter) with a median marginal applied dose of 14 Gy. METHODS Two hundred and thirteen patients diagnosed with AVMs were treated between January 1991 and December 2005. Seventy-three percent of the patients had hemorrhaged prior to treatment, 13% had ha...

BACKGROUND AND PURPOSE The purpose of this study was to define the risk of rebleeding after stereotactic radiosurgery (SRS) for hemorrhagic arteriovenous malformations with or without associated intracranial aneurysms. METHODS Between 1987 and 2006, we performed Gamma Knife SRS on 996 patients with brain arteriovenous malformations; 407 patients had sustained an arteriovenous malformation hem...
