Clinical validation of the avidin/indium-111 biotin approach for imaging infection/inflammation in orthopaedic patients.

We report here the results of a validation study of the avidin/indium-111 biotin approach in patients with skeletal lesions. This study involved 54 patients with orthopaedic conditions: 20 patients with intermediate suspected osteomyelitis of the trunk, 19 patients with infection/inflammation of prosthetic joint replacements, and 15 patients with suspected osteomyelitis of appendicular bones. Avidin (3 mg) was injected as an i.

Trocar site tumor recurrences. May pneumoperitoneum be responsible?

Background: Port site metastasis following laparoscopy for cancer is reported with increasing frequency and represents one of the most important limitations of the technique.

Methods: A scintigraphic model was utilized to evaluate a possible role of pneumoperitoneum in tumor cell dissemination. Labeled red blood cells (RBC) were injected at the level of the gallbladder bed during laparoscopic cholecystectomy (LC) performed for symptomatic cholecystolithiasis.

Multicenter randomized controlled clinical trial to evaluate cardioprotection of dexrazoxane versus no cardioprotection in women receiving epirubicin chemotherapy for advanced breast cancer.

Purpose: Dexrazoxane was found effective in reducing doxorubicin cardiotoxicity when given at a dose ratio (dexrazoxane: doxorubicin) of 20:1. Preclinical studies indicated that dexrazoxane at a dose ratio of 10 to 15:1 also protected against epirubicin-induced cardiotoxicity. The main objective of this study was to investigate the efficacy of dexrazoxane, given at a dose ratio of 10:1 against epirubicin cardiotoxicity.

Simultaneous dobutamine stress echocardiography and dobutamine scintigraphy (99mTc-MIBI-SPET) for assessment of coronary artery disease.

Background: Simultaneous dobutamine stress echocardiography (DSE) and 99Tc-MIBI-SPET (DMS) for the evaluation of the presence and the extent of coronary artery disease (CAD) were assessed for a head to head comparison regarding the diagnostic acuracy of the two rests.

Methods And Results: Forty-five consecutive patients (33 males and 12 females: 53 +/- 6.8 yr.

Comparison among sonography, double-tracer subtraction scintigraphy, and double-phase scintigraphy in the detection of parathyroid lesions.

Objective: This study prospectively evaluated the sensitivity of high-resolution sonography compared with double-tracer 201Tl-99mTc scintigraphy (Tl-Tc) subtractive scintigraphy and double-phase 99mTc-sestamibi (Tc-MIBI) scintigraphy prior to surgery in the assessment of patients with primary hyperparathyroidism in a geographic region where areas of endemic thyroid goiter are present.

Subjects And Methods: Sonography and scintigraphy were used as first-step imaging procedures in 73 patients with primary hyperparathyroidism. In 30 (41%) of 73 cases, we found an association with a thyroid abnormality.
