Authors and clinicians advocate lipase as the preferred serological test for the diagnosis for acute pancreatitis. While acute pancreatitis is among the differential diagnosis for elevated lipase levels, several other causes of elevated lipase levels have been identified including several reports Salmonella species as a causative agent. ⋯ However, Salmonella infections may induce elevated pancreatic enzyme levels without clinical pancreatitis or morphological pancreatic abnormalities through a variety of proposed mechanisms. The following is a case that describes a patient who developed Salmonella colitis and demonstrated elevated serum lipase levels without clinical pancreatitis.

Randomized Controlled Trial Comparative Study
Randomized comparison of three guidewire insertion depths on incidence of arrhythmia during central venous catheterization.
Guidewire-induced arrhythmias that occur during central venous catheterization can progress to malignant arrhythmias in rare cases. This study compared the incidence of arrhythmia during central venous catheterization using three different depths of guidewire insertion into the right internal jugular vein. ⋯ During central venous catheterization through the right internal jugular vein, inserting guidewires to depths of 15 or 17.5cm before tissue dilation reduced the incidence of arrhythmic episodes compared to a depth of 20cm.

Multicenter Study Comparative Study Observational Study
Missed myocardial infarctions in ED patients prospectively categorized as low risk by established risk scores.
Few studies have prospectively compared multiple cardiac risk prediction scores. We compared the rate of missed acute myocardial infarction (AMI) in chest pain patients prospectively categorized as low risk by unstructured clinical impression, and by HEART, TIMI, GRACE, and EDACS scores, in combination with two negative contemporary cardiac troponins (cTn) available in the U.S. ⋯ Using their recommended cutpoints and non high sensitivity cTn, TIMI and unstructured clinical impression were the only scores with no missed cases of AMI. Using lower cutpoints (GRACE≤48, TIMI=0, EDACS≤11, HEART≤2) missed no case of AMI, but classified less patients as low-risk.
