Short-term and long-term alterations of condylar position after bilateral sagittal split ramus osteotomy for mandibular setback: A preliminary before-after clinical trial.

Background: Because of the importance of the condyle, it is crucial to document all changes in its position after orthognathic surgery. Since previous studies in this regard are mostly controversial and limited by two-dimensional radiography technique, this study was conducted.

Materials And Methods: This prospective clinical trial was performed on 102 measurements (17 patients, 2 condyles each, and 3 time points).

Contrast Baths, Intramuscular Hemodynamics, and Oxygenation as Monitored by Near-Infrared Spectroscopy.

Context:: Contrast baths (CB) is a thermal treatment modality used in sports medicine, athletic training, and rehabilitation settings. Proposed physiological effects of CB include increasing tissue blood flow and oxygenation and decreasing tissue swelling and edema to promote better healing, improved limb function, and quicker recovery.

Objective:: To investigate the physiological effects of CB on the intramuscular hemodynamics and oxygenation of the lower leg muscles using near-infrared spectroscopy (NIRS), an optical method for monitoring changes in tissue oxygenated (OHb), deoxygenated (HHb), and total hemoglobin (tHb) as well as tissue oxygen saturation index (TSI%).

Subcutaneous and Intramuscular Hemodynamics and Oxygenation After Cold-Spray Application as Monitored by Near-Infrared Spectroscopy.

Context: Vapocoolant spray, commonly known as cold spray (CS), is a cryotherapy modality used in sports medicine, athletic training, and rehabilitation settings. Proposed physiologic effects of cryotherapy modalities include reductions in tissue blood flow, oxygenation, and cell metabolism in addition to attenuation of pain perception attributed to reduced superficial nerve conduction velocity.

Objective: To examine the effects of CS on subcutaneous and intramuscular blood flow and oxygenation on the thigh muscle using near-infrared spectroscopy, an optical method to monitor changes in tissue oxygenated (O2Hb), deoxygenated (HHb), and total (tHb) hemoglobin.

Suffolk Show 2011: prehospital medical coverage in a mass-gathering event.

Introduction: Despite their popularity and unique characteristics, county shows, also known as agricultural fairs, are amongst the least-studied mass-gathering events. Suffolk Show is one of the biggest such events in the UK, attracting tens of thousands of people annually over a 2-day period. In addition to trade stands and livestock displays, the 2011 show included top international show jumping and other sport activities.

A systematic review of tissue engineered meniscus: cell-based preclinical models.

Meniscal injuries are one of the common sports injuries and their natural healing is limited. Removal of injured meniscus alters knee biomechanics and predisposes patients to osteoarthritis. Tissue engineered meniscus provides a novel approach for the treatment of severe meniscus injury.
