Single-stage full-depth scalp reconstruction with Matriderm®: a clinical case report and a brief literature review.

Reconstructing scalp defects after basal cell carcinoma removal in elderly patients is challenging. This case report emphasizes Matriderm® as a successful alternative, addressing limitations of traditional methods. The application of Matriderm® in resource-limited scenarios adds insights to surgical literature, and its' usage addresses challenges in patients, contributing to surgical knowledge.

A case history of the science and management collaboration in understanding hypoxia events in Long Bay, South Carolina, USA.

Communication of knowledge between the scientific and management communities is a difficult process complicated by the distinctive nature of professional career goals of scientists and decision-makers. This article provides a case history highlighting a collaboration between the science and management communities that resulted from a response to a 2004 hypoxia, or low dissolved oxygen, event in Long Bay, off Myrtle Beach, South Carolina. A working group of scientists and decision-makers was established at the time of the event and has continued to interact to develop a firm understanding of the drivers responsible for hypoxia formation in Long Bay.

Cross-correlation quantification of dyssynchrony: a new method for quantifying the synchrony of contraction and relaxation in the heart.

Background: Quantification of left ventricular dyssynchrony using Doppler tissue imaging may improve selection of patients who will benefit from cardiac resynchronization therapy. Most methods used to quantify dyssynchrony use a time-to-peak analysis, which is quantitatively simplistic and requires manual identification of systole and selection of peak velocities.

Methods: We developed and tested a new, highly automatable dyssynchrony parameter, cross-correlation delay (XCD), that does not require identification of systole or manual selection of peak systolic velocities.
