Context: New Orleans narcotics detective Anthony Stowe (Jean-Claude Van Damme) is a heroin addict who is teetering on the edge of oblivion, and he couldn't care less.At the moment, Stowe is trying to bring down his former partner Gabriel Callahan (Stephen Rea), who has become a drug kingpin. Callahan is trying to, and slowly succeeding at, taking over the New Orleans underworld.Stowe botches a sting operation against Callahan, resulting in the death of fellow cop Maria Ronson (Rachel Grant), whose fiancee, fellow cop Van Huffel (Adam Leese), is furious at Stowe. Chief Mac Baylor (Gary Beadle) has a very blunt chat with Stowe about it. Stowe is approached by fellow cop Walter Curry (Trevor Cooper) to help his nephew beat a drug-dealing charge. Stowe instead turns him over to Baylor, who fires him. After barricading himself in the station bathroom, Walter confronts an unrepentant Stowe and condemns him for betraying his fellow officers.Later, Van Huffel berates Stowe for getting Maria killed. Stowe responds by attacking Van Huffel in front of several officers. Later, Stowe meets with his estranged wife Valerie (Selina Giles), who tells him that she's pregnant, but that he's not the father. Valerie, whose marriage with Stowe is on the rocks, has been seeing a man named Mark Rossini (Mark Dymond), the gym teacher at the school she is principle of. But he may not be the father either. Stowe brashly accuses Valerie of being impregnated by Callahan, and Valerie tells him she never wants to see him again.The only thing keeping Stowe from total collapse is his dogged pursuit of Callahan. But he drunkenly stumbles into an ambush masterminded by Callahan, and is shot in the head by Callahan's right-hand man Jimmy (Stephen Lord).Stowe undergoes emergency surgery, and ends up in a coma. Months later, he recovers to the point that he opens his eyes, and is transported to his and Valerie's house to recover properly.Seven months after getting shot, Stowe has recovered a lot, although he must learn to walk and speak again. He manages to survive an attempt on his life, by someone who appears to be a cop. He's recovered enough to try to get his job back, but that's the one thing that Chief Baylor doesn't want to give him. The coma has led to his decision to become a better man, and to right some wrongs. He reconciles with his wife, although awkwardly, and gives Walter a check for $40,000, part of his insurance money that compensated his time in a coma. Finally, he visits the grave of fellow police officer Serge (William Ash), who once saved Stowe's life but has been killed by an unknown attacker following another failed sting operation.Valerie packs up to move out of the house so she can live with Mark, but after realizing the change that Stowe has undergone, she later decides to leave Mark and come back home. Stowe is convinced by his friend Chad Mansen (Wes Robinson) not to let his wife go, and Stowe goes after her. They miss each other by a few minutes.Just after Valerie returns and meets Chad, some of Callahan's men show up. Jimmy kills Chad, and kidnaps Valerie. Stowe returns to the house, and finds Chad's body, along with Jimmy waiting for him.Van Damme promoting the film in 2007Jimmy takes Stowe to a warehouse where Callahan is waiting. Along the way, Stowe manages to overpower Jimmy and take his gun, but he finds that the odds against him are impossible- and Callahan has Valerie hostage. Van Huffel is revealed to be Callahan's mole on the police force, and the sting operation at the beginning of the film was a set-up. Walter suddenly arrives and saves Stowe. Together they kill all of Callahan's men, including Jimmy and Van Huffel, as Callahan tries to escape with Valerie to his helicopter. Just as Callahan is about to reach it, Stowe appears.In the European DVD ending, each fire a shot that kills the other. Valerie cries out

Context: Benzodiazepine (BZD) overdose (OD) continues to cause significant morbidity and mortality in the UK. Flumazenil is an effective antidote but there is a risk of seizures, particularly in those who have co-ingested tricyclic antidepressants. A study was undertaken to examine the frequency of use, safety and efficacy of flumazenil in the management of BZD OD in the UK. A 2-year retrospective cohort study was performed of all enquiries to the UK National Poisons Information Service involving BZD OD. Flumazenil was administered to 80 patients in 4504 BZD-related enquiries, 68 of whom did not have ventilatory failure or had recognised contraindications to flumazenil. Factors associated with flumazenil use were increased age, severe poisoning and ventilatory failure. Co-ingestion of tricyclic antidepressants and chronic obstructive pulmonary disease did not influence flumazenil administration. Seizure frequency in patients not treated with flumazenil was 0.3%. The frequency of prior seizure in flumazenil-treated patients was 30 times higher (8.8%). Seven patients who had seizures prior to flumazenil therapy had no recurrence of their seizures. Ventilation or consciousness improved in 70% of flumazenil-treated patients. Flumazenil administration was followed by one instance each of agitation and brief seizure. Flumazenil is used infrequently in the management of BZD OD in the UK. It was effective and associated with a low incidence of seizure. These results compare favourably with the results of published randomised controlled trials and cohort studies, although previous studies have not reported the use of flumazenil in such a high-risk population. This study should inform the continuing review of national guidance on flumazenil therapy. 
 Question: Which drug should be used as an antidote in benzodiazepine overdose?

flumazenil

However, the Steelers took the lead later on in the quarter when Ben Roethlisberger found Markus Wheaton on an 18-yard TD pass for a 7-3 game. In the 2nd quarter, the Steelers would score again increasing their lead as Roethlisberger found Martavis Bryant on a 5-yard TD pass for a 14-3 game. This was followed by William Gay picking off Andrew Luck and returning it 33 yards for a TD as they increased their lead to 21-3. The Colts however responded as Andrew Luck threw a 21-yard TD pass to Dwayne Allen for a 21-10 game. However, the Steelers pulled away as Roethlisberger would find Antonio Brown on 2 consecutive TD passes: from 8 and 47 yards out to increase their lead at first from 28-10 to 35-10. The Colts responded with 10 straight points first being Luck who found T. Y. Hilton on a 28-yard TD Pass for a 35-17 game followed by Vinatieri kicking a 23-yard field goal before halftime to make the score 35-20. The Steelers went back to work in the 3rd quarter as Roethlisberger and Bryant hooked up again on a 2-yard TD pass to increase their lead making the score 42-20. The Colts however were able to come within 8 later on when Ahmad Bradshaw ran for a 12-yard TD followed by Luck finding Donte Moncrief on a 31-yard TD pass to make the score 42-27 and then 42-34. In the 4th quarter, it was all Steelers when a penalty was enforced on Luck in the end zone for a safety making the score 44-34.
