Western blotting is a ubiquitous tool used in protein and molecular biology research, providing information about the presence, size, relative abundance, and state of a protein in a mixture. First, the proteins in a sample are separated by size using SDS-PAGE then transferred onto a membrane for detection with a set of primary and secondary antibodies. High-quality Western data requires high signal-to-noise ratios, which depend upon reduction of nonspecific antibody interactions.

Purposes Of Review: This review summarizes new findings in the field of maltreatment, addressing epidemiology, physical abuse, abusive head trauma, sexual abuse, sequelae, and prevention.

Recent Findings: Many articles this year focus on establishing a framework for thinking about how to evaluate a child for maltreatment, the consequences of maltreatment, and the current understanding of prevention efforts. Interestingly, some research has helped to reinforce some concepts that were clinically appreciated, especially related to retinal hemorrhages.

Article Synopsis
  • - The study aimed to assess how often non-cutaneous mimics (conditions that can resemble abuse) were identified in a large group of children suspected of physical abuse, involving nearly 2900 consultations across multiple centers.
  • - Out of these, 137 children (4.7%) had conditions classified as mimics, with 81 cases (2.8% of the cohort) involving non-cutaneous issues, including metabolic disorders and infections.
  • - The research highlights the need for pediatric care providers to recognize these mimics, as identifying one does not rule out the possibility of actual abuse, with some children still receiving high concern ratings for abuse even after a mimic was identified.

Incorrect diagnoses during child abuse evaluations are serious. Because skin lesions are common in abuse, it is important to consider cutaneous mimics of physical abuse. The current study prospectively identified cutaneous mimics in a cohort of children evaluated for possible physical abuse.

This article explores how child abuse physicians (CAPs) experience the unique challenges of the emerging field of child abuse pediatrics. Practicing CAPs completed a written survey about known challenges in their field. Fifty-six CAPs completed the written survey and reported experiencing many negative consequences including: threats to their personal safety (52%), formal complaints to supervisors (50%) and licensing bodies (13%), negative stories in the media (23%), and malpractice suits (16%).

Robotic technology enables "port only" totally endoscopic coronary artery bypass grafting (TECAB). During early procedure development only single bypass grafts were feasible. Because current referral practice for coronary bypass surgery mostly includes multivessel disease, performance of multiple endoscopic bypass grafts is desirable.

Background: Concerns about intimal disruption and spasm have limited enthusiasm for endoscopic radial artery harvest (ERAH), although the risk of these problems after this procedure remains uncertain. Radial artery conduits were screened intraoperatively before and after ERAH vs open harvest using catheter-based high-resolution optical coherence tomography (OCT) imaging.

Methods: Twenty-four cadavers and 60 coronary artery bypass graft (CABG) patients scheduled to receive a RA graft underwent OCT imaging before (in situ) and after (ex vivo) open harvest or ERAH.

Objective: Residual clot strands within the excised saphenous vein are an increasingly recognized sequela of endoscopic vein harvest. We hypothesized that endoscopic visualization facilitated by sealed carbon dioxide insufflation causes stagnation of blood within the saphenous vein. In the absence of prior heparin administration, this stasis provokes clot formation.

Objectives: Endothelial disruption within saphenous vein and radial artery grafts increases thrombosis risk. However, no clinically applicable method for imaging the intima currently exists. We used a novel infrared imaging technology, optical coherence tomography (OCT; LightLab Imaging, Inc, Westford, Mass), to visualize the intima within harvested conduits.

Background: Debate continues between on-pump or off-pump approach for coronary artery bypass grafting (CABG). We used off-pump coronary artery bypass grafting (OPCAB) as a tool within a decision-making algorithm driven by the patient-related factors of coronary anatomy and comorbidity. Our analysis presents this decision algorithm and describes outcomes using this approach.

Objective: : Strands of clot are frequently flushed out of saphenous vein grafts (SVG) during preparation for grafting, particularly those that are endoscopically harvested. However, saline distention at uncontrolled pressures increases graft thrombogenicity and the risk of early failure after coronary artery bypass grafting. The purpose of this prospective investigation was to define the incidence of intraluminal clot within endoscopically harvested SVG and the effect of attempted removal by saline distention.

Background: The Cox Maze III operation remains the gold standard for the surgical treatment of atrial fibrillation (AF). We report our experience using a flexible argon-powered metal cryoprobe for creation of the complete Cox-Maze III lesion set in patients with AF (the CryoMaze operation).

Methods: Beginning July 2002, 38 patients underwent the CryoMaze operation.
