Simultaneous fine-needle aspiration and core biopsy of thyroid nodules and other superficial head and neck masses using sonographic guidance.
The objective of our study was to conceive of and to evaluate a simple system for simultaneous fine-needle aspiration (FNA) and core biopsy of thyroid nodules when FNA alone has failed to yield tissue adequate for diagnosis. ⋯ The use of a modified coaxial guiding needle and biopsy gun is a simple, safe, and effective method for obtaining tissue from thyroid nodules and is applicable to sampling other superficial masses as well.

Effect of artificial ascites on thermal injury to the diaphragm and stomach in radiofrequency ablation of the liver: experimental study with a porcine model.
The purpose of this study was to evaluate the effect of artificial ascites on thermal injury to the diaphragm and stomach in a porcine model of radiofrequency ablation of the liver. ⋯ Artificial ascites may be a simple and useful technique for reducing the frequency and severity of collateral thermal injury to the diaphragm and stomach during radiofrequency ablation of subcapsular hepatic tumors.

Randomized Controlled Trial Comparative StudyCost-effectiveness and patient tolerance of low-attenuation oral contrast material: milk versus VoLumen.
The purpose of our study was to prospectively compare the cost, effectiveness, and patient tolerance of milk and VoLumen, a 0.1% barium suspension, in patients undergoing abdominal and pelvic CT with oral and i.v. contrast media. ⋯ Whole milk is comparable to VoLumen with respect to bowel distention and bowel wall visualization and has a lower cost, better patient acceptance, and fewer adverse symptoms. Milk is a cost-effective alternative to VoLumen as a low-attenuation oral contrast agent.

Controlled Clinical TrialUsefulness of laryngeal phonation CT in the diagnosis of vocal cord paralysis.
The purpose of this study was to determine the effectiveness of laryngeal phonation CT for the diagnosis of vocal cord paralysis by examining the physiologic and functional changes in the larynx during vowel phonation in patients with vocal cord paralysis. ⋯ Laryngeal phonation CT proved more useful for evaluating vocal cord paralysis than did conventional CT and can be used as a primary diagnostic tool when vocal cord paralysis is suspected.

Clinical TrialPractical experience with sonographically guided phenol instillation of stump neuroma: predictors of effects, success, and outcome.
Phantom limb pain and stump pain frequently occur after limb amputation, and stump neuromas play an important role in generation of the pain. The purpose of this study was to evaluate the effects of a previously described optimized procedure for sclerosis of painful stump neuromas under real-time high-resolution sonographic guidance. ⋯ The high-resolution sonographically guided neurosclerosis procedure had a significantly better outcome than other documented treatments. Sonographically guided neurosclerosis should be included in the management of chronic phantom limb and stump pain.
