Context: One of the primary criticismes of vestibular schwannoma (VS) radiosurgery is that the risk of surgical morbidity is increased for patients whose tumor progresses after the procedures. We reviewed the French experience of operated patients after failed Gamma Knife radiosurgery. From July 1992 to January 2002, 25 out of the 1000 treated patients underwent another treatment procedure for a gamma knife failure. Excluding the NF2 patients, 21 patients have been operated and the present study shows the data collected for 20 of them. In order to analyze the difficulties observed during the surgery, a questionnaire was filled by the surgeons. The mean interval between radiosurgery and removal was 36 Months, from 10 to 83 Months. The mean increase in Volume was 559% (37 to 3036%, median 160%). Evolution of the Koos grading was found from 8 grade II, 10 grade III et 2 grade IV to 10 grade III and 10 grade IV. Patients have been operated for radiological tumor growth in 7 cases and for clinico-radiological evolution in 13 cases. In 9 cases, the surgeon considered that he had to face unusual difficulties mainly because of adhesion of the tumor to neurovascular structures. Tumor removal was total in 14 cases, near total in 4 cases and subtotal in 2 cases. One case of venous infarction was noticed at the second day following surgery responsible of hemiparesis and aphasia that gradually recovered. At last follow-up examination, facial nerve was normal (House and Brackmann grade I and II) in 10 cases while it was a grade III in 7 cases and grade IV and V in 3 cases. We recommend that the decision for surgical removal of growing vestibular schwannoma after Gamma Knife treatment should be done after a sufficiently long follow-up period. Our results show that the quality of removal and of facial nerve preservation might be impaired by radiosurgery in half of cases. However these results do not support a change in our policy of radiosurgical treatment of small to medium size vestibular schwannoma.

Context: Coming off their bye week, the Jets stayed at home for a Week 10 duel with the Jacksonville Jaguars. New York would trail early in the first quarter with running back Maurice Jones-Drew's 33-yard touchdown run. The Jets would respond with kicker Jay Feely getting a 32-yard field goal, followed by rookie quarterback Mark Sanchez completing a 7-yard touchdown pass to wide receiver Jerricho Cotchery. In the second quarter, Jacksonville would take the lead as quarterback David Garrard got an 11-yard touchdown run and completed a 26-yard touchdown pass to wide receiver Mike Sims-Walker. New York would close out the half as Feely made a 37-yard field goal. After a scoreless third quarter, the Jets would regain the lead in the fourth quarter with a 40-yard field goal from Feely and a 1-yard touchdown run from running back Thomas Jones (with a failed 2-point conversion). However, the Jaguars got the last laugh as kicker Josh Scobee booted the game-winning 21-yard field goal. 
 Question: Which team scored the first field goal?

Ex Output:
