Compressive neuropathies related to ganglions of the wrist and hand.

Ganglions of the wrist and hand causing compressive neuropathies are rare clinical entities. Compression of the ulnar and median nerves in their respective fibro-osseous tunnels lead to characteristic patterns of motor and/or sensory deficits, which are directly related to the location of the lesion. We present a unique case of a "dumbbell" shaped ganglion invading both Guyon's canal and the carpal tunnel causing a dual compressive neuropathy of the ulnar and median nerve.

Reliability of sonographic assessment of tendinopathy in tennis elbow.

Objective: To assess the reliability and compute the minimum detectable change using sonographic scales to quantify the extent of pathology and hyperaemia in the common extensor tendon in people with tennis elbow.

Materials And Methods: The lateral elbows of 19 people with tennis elbow were assessed sonographically twice, 1-2 weeks apart. Greyscale and power Doppler images were recorded for subsequent rating of abnormalities.

Measurement issues in the sonographic assessment of tennis elbow.

Sonography is increasingly being used for assessment in tennis elbow research and clinical practice, but there are a lack of data regarding its validity, reliability, and responsiveness to change for this application. Studies using the modality were reviewed to establish current levels of evidence for these measurement properties. There is reasonable evidence regarding its validity for identifying tennis elbow tendinopathy, but a lack of data addressing its reliability and responsiveness.

Enhancement characteristics of the microbubble agent Levovist: reproducibility and interaction with aspirin.

We investigated the reproducibility of Doppler enhancement indices following intravenous bolus injections of Levovist (Schering AG, Berlin) microbubbles. We also aimed to determine whether observations from animal studies suggesting that aspirin potentiates microbubble enhancement were reproducible in humans. In five healthy volunteers, time enhancement profiles of Doppler intensity following repeated bolus injections of Levovist were acquired from the common carotid artery, hepatic vein and kidney using spectral and power Doppler before and after oral aspirin (600 mg).
