Impact of Material Shade and Distance from Light Curing Unit Tip on the Depth of Polymerization of Composites.

This study aimed to evaluate the effect of the composite shade and distance from the light-curing unit (LCU) tip on the irradiance reaching the bottom of composite disks and on the depth of polymerization. Composites of three shades (opaque - OXDC, bleach - BXL, and A2) were inserted into molds with 3-mm of thickness positioned over a spectrometer and photo-activated with the LCU (Bluephase) tip placed at 0 or 1 cm from the composite surface. The mean irradiance reaching the bottom of composite was recorded during the entire photo-activation (30 s).

Medication persistence in older women with osteoporosis: a pilot study.

Unlabelled: Most osteoporosis patients stop their medications before they should. Side effects are the most common reason patients in this sample stopped their medication before they told their physician. Physicians should use shared decision-making and discuss side effects of osteoporosis medications with their patients and explain the risks of the medications.

Not Your Everyday Case of Acute Pancreatitis: A Rare Complication of a Common Diagnosis.

Pancreaticopericardial fistula is an extremely rare complication of chronic pancreatitis and is virtually unheard of in the setting of acute pancreatitis. A 67-year-old male presented with acute pancreatitis complicated by pancreaticopericardial fistulization. The patient's initial presentation was consistent with tamponade physiology.
