Mucus clears from the trachea in a helix: a new twist to understanding airway diseases.

Background: Mucociliary clearance (MCC) is critical to lung health and is impaired in many diseases. The path of MCC may have an important impact on clearance but has never been rigorously studied. The objective of this study is to assess the three-dimensional path of human tracheal MCC in disease and health.

Glossopharyngeal insufflation causes lung injury in trained breath-hold divers.

Background And Objective: Glossopharyngeal insufflation (GI) is a technique practised by competitive breath-hold divers to enhance their performance. Using the oropharyngeal musculature, air is pumped into the lungs to increase the lung volume above physiological TLC. Experienced breath-hold divers can increase their lung volumes by up to 3 L.

Radionuclide bone scintigraphy in sports injuries.

Bone scintigraphy is one of the mainstays of molecular imaging. It has retained its relevance in the imaging of acute and chronic trauma and sporting injuries in particular. The basic reasons for its longevity are the high lesional conspicuity and technological changes in gamma camera design.

Bone scintigraphy predicts outcome of steroid injection for plantar fasciitis.

Unlabelled: Plantar fasciitis is a common cause of foot pain and may be disabling. Although localized injection is painful, anesthetics or corticosteroids can relieve symptoms well. Bone scintigraphy can confirm the diagnosis.

Blunt trauma soft-tissue uptake on skeletal scintigraphy.

Muscle and soft-tissue uptake have been described numerous times in the literature in patients undergoing Tc-99m methylene diphosphonate skeletal scintigraphy following trauma. Many of these traumas range from electrical burns, intramuscular injections, sports-related trauma, and overexercising, to actual physical damage resulting in superficial bruising and skin discoloration. In this case the patient presented with continuing low back pain after falling down some stairs.

A critical appraisal of pinhole scintigraphy of the ankle and foot.

Background: Scintigraphy is an established imaging technique for injuries of the ankle and foot that are not apparent on plain radiographs. The scintigraphic technique has varied, with planar and pinhole images being used.

Materials And Methods: The incremental value of pinhole scintigraphy over planar imaging was studied in 16 patients with established diagnoses.

Scintigraphy of injuries to the distal tibiofibular syndesmosis.

Ankle sprains are a common injury and may occur in as many as 75% of sporting participants. More complex injuries involving a rotational component may lead to injury of the interosseous membrane, its supporting ligaments, or the tibial plafond, compromising the integrity of the ankle mortice. Four such cases that show the scintigraphic manifestation of the injury are presented.

Distinguishing scintigraphic features of spondylolysis.

A scintigraphic pattern of increased uptake was observed in the pedicles of the affected segment and a triangular pattern of uptake in the sagittal projection of tomographic studies of pars fractures. It was hypothesised that these observations were specific for pars fractures. A retrospective study of 25 young athletes (age 9-16 years) with a variety of spinal disorders was undertaken.
