Use of an optical surface scanner in assessment of outcome following rhinoplasty surgery.

Objective: To demonstrate the use of an optical surface scanner, with associated software, in the assessment of rhinoplasty patients, and to discuss the possible clinical applications of this technology in the future.

Design: Case study analysis of pre- and post-operative scans of a patient undergoing septorhinoplasty at Whipps Cross University Hospital, London, UK.

Subject: A 21-year-old man undergoing septorhinoplasty underwent pre-operative optical surface scanning of his face.

The transverse pelvic plane: a new and practical reference frame for hip arthroplasty.

Acetabular orientation is a crucial part of the planning and performance of hip arthroplasty. Currently, most surgeons use the anterior pelvic plane (APP) to orient themselves when navigating the acetabulum, despite the fact that the anterior superior iliac spine (ASIS) of the unaffected side is not accessible in the lateral position. We have identified another plane, the transverse pelvic plane (TPP), relying on both posterior superior iliac spines and the ASIS of the affected side.

MnTMPyP, a metalloporphyrin-based superoxide dismutase/catalase mimetic, protects INS-1 cells and human pancreatic islets from an in vitro oxidative challenge.

Aims: Pancreatic islets can be lost early following allotransplantation from oxidative stress. Antioxidant enzyme overexpression could confer a beneficial effect on islets exposed to reactive oxygen species (ROS) and nitrogen species. Here, we tested the effect of MnTMPyP, a superoxide dismutase/catalase mimetic.

Validation of the conceptual anatomical model of the lung airway.

The conceptual anatomical model of the lung airway considers each lung volume divided into ten concentric shells. It specifies the volume of each airway generation in each shell, using Weibel morphometry. This study updates and validates the model and evaluates the errors obtained when using it to estimate inhaled aerosol deposition per generation from spatial imaging data.

Overcoming subjectivity in assessing facial lipoatrophy: is there a role for three-dimensional laser scans?

Background: Prevalence and incidence rates of lipodystrophy vary widely and frequently rely upon self- and/or clinician reports. Currently no validated assessment tool for facial lipoatrophy is available.

Aims And Objectives: To illustrate that assessment of the severity of facial lipoatrophy by patients and clinicians is subjective.
