Digital Volumetric Measurements Based on 3D Scans of the Lower Limb: A Valid and Reproducible Method for Evaluation in Lymphedema Therapy.

Background: Exact quantification of volumetric changes of the extremities is difficult and often error-prone. The aim of this study was to establish a standardized method based on 3-dimensional (3D) scans. Furthermore, this study tests the method in terms of reproducibility and evaluates volume changes after surgical therapy in patients suffering from lymphedema on the lower extremity.

Factors influencing the shape, size, symmetry and scar of the nipple-areola complex after bilateral reduction mammoplasty.

Background: Asymmetry and scar formation of the nipple-areola complex (NAC) after reduction mammoplasty with periareolar suture are common complications and can significantly affect patient satisfaction.

Objective: The aim of this study was to investigate possible procedure-specific influencing factors on asymmetry and shape disturbances of the nipple-areola complex to optimize postoperative outcome and thus improve patient satisfaction.

Methods: 78 patients were followed-up after a 5-year period as part of a retrospective cohort study.

Comparing the effectiveness of novel high-end compression garment with common compression garment and kinesio tape in preventing edema and improving tissue perfusion in lower extremities.

Context: Global sales of compression garments have risen sharply in recent years. Due to the availability of a wide range of compression garments, this study aims to evaluate the effect of two types of compression garments and kinesio tape on edema formation and tissue perfusion in the lower extremities. Over-the-counter compression knee stockings and kinesio tape were compared with a prototype of high-end compression stockings that combine kinesio tape and a common knee bandage.

Temperature Dependence of Photoluminescence Intensity and Spin Contrast in Nitrogen-Vacancy Centers.

We report on measurements of the photoluminescence properties of single nitrogen-vacancy centers in diamond at temperatures between 4 K and 300 K. We observe a strong reduction of the PL intensity and spin contrast between ca. 10 K and 100 K that recovers to high levels below and above.

Surface imaging of breast implants using modern high-frequency ultrasound technology in comparison to high-end sonography with power analyses for B-scan optimization1.

Aim: This study aims to evaluate optimized breast implant surface-structure analysis by comparing high-end ultrasound technology with a new high frequency technique. This comparative study used new breast implants with different surfaces in an in vitro setting.

Methods: Nine idle silicon or polyurethane (PU) breast implants were examined by two investigators in an experimental in vitro study using two high-end ultrasound devices with multi-frequency transducers (6-15 MHz, 9-16 MHz, 12.
