Apichet Kittikorncharoen (Thai: อภิเชษฐ์ กิตติกรเจริญ;, name later changed to Panrawat (Thai: ปาณรวัฐ), 2 December 1982 – 9 December 2007) was a Thai singer known under the stage name Big D2B. He studied film at Bangkok University and was part of RS Promotion's trio boy band D2B.
On 22 July 2003, a car accident in which he fell into a polluted Bangkok khlong (canal) resulted in severe brain infection with multiple organisms including the fungus known as Scedosporium (ex. Pseudoalleschia) boydii,[2] which, despite efforts to treat him including four brain operations and medicine flown in from Australia,[3] caused extensive damage to his brain. He remained in coma for four years before finally passing away on 9 December 2007.[4] Apichet's case, which saw throngs of fans hoping and praying for him at the hospital as well as intense media attention, helped raise awareness about the hazardous nature of Bangkok's water pollution.[5] His funeral was held for 100 days from the end of 2007 to March of the next year, and was patronised by Queen Sirikit.[6]
