Applying Ockham??s Razor to Pancreatitis Prognostication

Applying Occam's razor to paper (and rock and scissors, too): Why simpler models are sometimes better

A commonly held idea is that people engaged in guessing tasks try to detect sequential dependencies between the occurring events and behave accordingly. For instance, previous accounts of the popular Rock Paper Scissors game assume that people try to anticipate the move an opponent is likely to make and play a move capable of beating it. In the paper we propose that players modulate their behav...

Occam's Razor

The Bayesian paradigm apparently only sometimes gives rise to Occam’s Razor; at other times very large models perform well. We give simple examples of both kinds of behaviour. The two views are reconciled when measuring complexity of functions, rather than of the machinery used to implement them. We analyze the complexity of functions for some linear in the parameter models that are equivalent ...

Anaphylactic reaction due to razor shell

Background a 36-year-old woman, with a history of childhood asthma allergic to house dust mites, noticed one year prior to her arrival at our unit an episode of generalized itching, dyspnea, severe rhinoconjunctivitis and abdominal pain after eating rice with razor shell. After that, she had tolerated rice alone. Razor shell (Ensis ensis) is a common mollusc, which has an elongated fragile and ...

Severity assessment of acute pancreatitis: applying Marshall scoring system.

OBJECTIVE To analyze the effectiveness of the Marshall scoring system to evaluate the severity of acute pancreatitis (AP). METHODS We performed a prospective, observational study in 39 patients with AP evaluated by the Marshall scoring system and the Ranson criteria (admission and 48 hours). We assessed the progression of the disease for seven days and compared the data of the two criteria. ...
