Lettris is a curious tetris-clone game where all the bricks have the same square shape but different content. Each square carries a letter. To make squares disappear and save space for other squares you have to assemble English words (left, right, up, down) from the falling squares.
Boggle gives you 3 minutes to find as many words (3 letters or more) as you can in a grid of 16 letters. You can also try the grid of 16 letters. Letters must be adjacent and longer words score better. See if you can get into the grid Hall of Fame !

Analgesic nephropathy is a cause of renal papillary necrosis. The damage is cumulative and most patients of renal papillary necrosis would have ingested at least 20kg of analgesics in the past. The risk is higher for phenacetin and acetaminophen compared to aspirin and other NSAIDs. Combination analgesic products, such as Goody's, also have a high risk of causing papillary necrosis.
It can be an outcome of chronic analgesic nephritis, with persistent use or abuse of phenacetin or its derivatives (such as Acetaminophen). This is less common since phenacetin is no longer available over the counter. But is more common when patient's taken combination analgesic products for an extended period of time.
It is also caused by diabetes mellitus and vaso-occlusive sickle cell crisises, in which it is related to renal infection or vascular disease.
