Advantages and techniques of utilizing anterolateral portal in delaminated rotator cuff repair.

Typically, rotator cuff repair is performed two-dimensionally while visualizing the subacromial space. To achieve a more complete repair, sutures can be retrieved from inside the joint utilizing a penetrating suture device through the anterolateral portal, which permits visualization of the articular side and bursal side of the rotator cuff tear. Utilizing other portals can leave the sutures out of sight and reach.

A study to evaluate and compare the efficacy of preprocedural mouthrinsing and high volume evacuator attachment alone and in combination in reducing the amount of viable aerosols produced during ultrasonic scaling procedure.

Background And Objectives: In recent years, ultrasonics has gained prime importance and is considered a valuable tool in the dentist's armamentarium. Studies have confirmed that an aerosolized bacterial contamination is produced during the use of ultrasonic scalers.

Aim: To evaluate and compare the efficacy of preprocedural mouthrinsing using a bis-biguanide (chlorhexidine gluconate 0.

Innervation of the supinator muscle and its relationship to two-incision distal biceps tendon repair: an anatomic study.

Reinsertion of the ruptured distal biceps tendon has been performed using either a single-anterior incision or a two-incision approach. A systematic review of these two repair methods has identified a higher incidence of supination weakness following the two-incision approach. The objective of this study was to describe the innervation of the supinator muscle and its implications regarding a two-incision distal biceps repair.

Repair of the ruptured distal biceps tendon: a systematic review.

Background: Reinsertion of the acutely ruptured distal biceps is the preferred method of treatment for most patients and is designed to restore flexion and supination strength. It is not clear which, if any, method of fixation is superior or whether a 2-incision or single-incision approach is associated with fewer complications or better outcomes.

Hypotheses: (1) There is no difference in biomechanical performance between currently used fixation methods, (2) there is no difference in incidence of complications between the 2-incision and single-incision approach, and (3) there is no difference in clinical outcomes between the 2-incision and single-incision approach.

Evaluation of small-scale constructed wetland for water quality and Hg transformation.

Elevated concentrations of nutrients and mercury (Hg) make Steamboat Creek (SBC) the most polluted tributary of the Truckee River. Since wetlands are considered cost-effective, reliable, and potential sites for methylmercury (MeHg) production, a small-scale wetland system was constructed and monitored for several years in order to quantify both nutrient removal and transformation of mercury. Results indicated seasonal variations in nutrient removal with 40-75% of total nitrogen and 30-60% of total phosphorus being removed with highest removals during summer and lowest removals during winter.

Evaluation of wetland methyl mercury export as a function of experimental manipulations.

Mercury associated with natural enrichment, historic mining, and ore processing is a contaminant of concern in watersheds of the western USA. In this region, water is a highly managed resource and wetlands, known to be important sites of methyl mercury production, are often an integral component of watersheds. This study applied controlled manipulations of four replicated experimental wetland designs with different water and soil mercury concentrations to determine the potential impacts on methyl mercury export.
