Scrims both reflect and transmit light. 1  This means that if a light from a front-of-house position is shone at a scrim, then both the scrim and everything behind it will be lit. This can lead to a variety of interesting effects: 1  A scrim will appear entirely opaque if everything behind it is unlit and the scrim itself is grazed by light from the sides or from above. 2  A scrim will appear nearly transparent if a scene behind it is lit, but there is no light on the scrim.
Acalculous cholecystitis. Acalculous cholecystitis is a less common, but usually more serious, type of acute cholecystitis. It usually develops as a complication of a serious illness, infection or injury that damages the gallbladder. Acalculous cholecystitis is often associated with problems such as accidental damage to the gallbladder during major surgery, serious injuries or burns, blood poisoning (sepsis) , severe malnutrition or AIDS.
Although most people with gallstones do not have symptoms and will not go on to develop cholecystitis, cholecystitis occurs most commonly due to blockage of the cystic duct with gallstones (cholelithiasis).he symptoms of cholecystitis are similar to biliary colic but the pain becomes more severe and constant. Nausea is common and vomiting occurs in 75% of people with cholecystitis. In addition to abdominal pain, right shoulder pain can be present.
