NMR-based newborn urine screening for optimized detection of inherited errors of metabolism.

Inborn errors of metabolism (IEMs) are rare diseases produced by the accumulation of abnormal amounts of metabolites, toxic to the newborn. When not detected on time, they can lead to irreversible physiological and psychological sequels or even demise. Metabolomics has emerged as an efficient and powerful tool for IEM detection in newborns, children, and adults with late onset.

Sonographically guided percutaneous needle lavage in calcific tendinitis of the shoulder: short- and long-term results.

Objective: The purpose of our study was to evaluate the short- and long-term effectiveness of sonographically guided percutaneous needle aspiration and lavage in calcific tendinitis of the shoulder and to study the progress of calcifications and symptoms in the first year after treatment.

Materials And Methods: Symptoms and radiologic findings after percutaneous aspiration of calcific tendinitis were prospectively evaluated in the short and the long term using a shoulder pain and disability index, evaluation of shoulder motion, and a survey of the self-perception by the patients regarding the progress of their disease.

Results: Sixty-seven consecutive shoulders were treated.

The use of unenhanced Doppler sonography in the evaluation of solid breast lesions.

Objective: The objectives of our study were to investigate differences in Doppler sonography features between benign and malignant breast lesions and between malignant lesions with different prognostic factors and to propose diagnostic criteria for Doppler sonography of breast lesions.

Subjects And Methods: We performed power and duplex Doppler sonography examinations in 826 breast lesions scheduled for sonographically guided core needle biopsy. Lesion vascularity, pulsatility index (PI), and resistive index (RI) of the vessels detected were analyzed and correlated with histologic results.
