Light chain deposition disease presenting as an atrial mass: a case report and review of literature.

Light chain deposition disease (LCDD) also known as nonamyloidotic immunoglobulin deposition disease is a rare systemic disorder due to the abnormal deposition of immunoglobulin in multiple organs caused by the clonal proliferation of B lymphocytes and plasma cells. Renal involvement is the most common with cardiac manifestations being the most common extra renal presentation of the disease. Renal involvement is not always associated with LCDD.

A simple ABCD score to stratify patients with respect to the probability of survival following in-hospital cardiopulmonary resuscitation.

Background: Cardiopulmonary resuscitation (CPR) is occurring more frequently at community hospitals but most patients undergoing CPR do not survive to discharge. Tools to predict CPR survival can be improved by the identification of high-yield clinical indicators.

Objective: To identify variables associated with survival to discharge following in-hospital cardiac arrest.

Coccygeal Polypoid Eccrine Nevus Presenting as a Skin Tag: Case Report and Review of the Literature.

Coccygeal polypoid eccrine nevi (CPEN) are rare, benign, cutaneous polypoid lesions localized to the coccyx region that are characterized by areas of hyperplastic eccrine ducts without hyperhidrosis. We present the case of an asymptomatic 16-month-old female with a congenital lesion in the lower sacral area and review the literature and the differential diagnosis for CPEN.

Characterizing constraining forces in the alignment phase of orthodontic treatment.

Objectives: To describe the frictional forces (FF) that constrain wire sliding in the initial alignment phase of treatment using a new term, the "constraining force" (CF), and to hypothesize that CF is dependent on two factors: the hyperelastic behavior of archwires and the specific type of tooth geometric malalignment present.

Materials And Methods: A laboratory device that simulates the four distinct malalignment types (in-out, rotation, tipping, and vertical step) was used to couple with an Instron testing apparatus. Incremental CF data for the four types of malalignment were recorded.

Dentin bonding of an etch-and-rinse adhesive using self- and light-cured composites.

Purpose: To evaluate the dentin shear bond strength (SBS) of a new two-step etch-and-rinse adhesive system (MPa Direct) using self- and light-cured composites.

Methods: The dentin of 160 bovine teeth was ground to 600 grit. Self- (Bisfil 2B) or light-cured (Filtek Supreme Plus) composite was bonded to dentin using MPa Direct, Adper Single Bond Plus, One-Step Plus, OptiBond Solo Plus, or Prime & Bond NT.
