Julio Bonis, Family Medicine Resident Fundación Jimenez Díaz, 28004, Madrid, Spain Send response to journal: Re: A previously described clinical injury	cowley and Minnar describe in their article a injury related with use of Wii videogame. First case of wiiitis (original term used to describe the wii shoulder) was described and suffered by myself in June 2007, as published in the New England Journal of Medicine. For that reason I think authors should have done a deeper review of previous literature about the issue and put a reference to the original article: Bonis J. Acute Wiiitis. N Engl J Med. 2007 Jun 7;356(23):2431-2. Dr Julio Bonis Competing interests: First author describing "wii shoulder"
Retroperitoneal Haemorrhage from Ruptured Angiomyolipoma while Playing Wii © Video Games 26 August 2008

Gonzalez Send response to journal: Re: Retroperitoneal Haemorrhage from Ruptured Angiomyolipoma while Playing Wii © Video Games	Haemorrhage of renal angiomyolipoma (AML) has classically been described as occurring spontaneously or associated with trauma. A young woman with a history of incidentally identified AML presented to the emergency department complaining of three to four days of discomfort. The patient reported playing the Wii © Sports video game aggressively when she experienced left-sided pain accompanied by lightheadedness, abdominal cramping, nausea and vomiting. In the emergency department, the patient was found to be tachycardic to a heart rate of 120 bpm and complained of light-headedness. Laboratory evaluation revealed a haemoglobin of 8.5 g/dl. A CT scan of her abdomen identified acute rupture of a 10 cm AML on the superior pole of the left kidney with associated active extravasation and a retroperitoneal haematoma. She was subsequently admitted for monitoring but the following morning her haemoglobin had dropped to 6.8 g/dl with persistent abdominal pain. She underwent angiography and catheter directed embolization of the mass with subsequent recovery. We believe this is the first case in which retroperitoneal haemorrhage has been linked to video game usage. Competing interests: None declared Editorial note The patient whose case is described has given her signed informed consent to publication.
