Complementary role of magnetic resonance imaging in the study of the fetal urinary system.

Urinary system birth defects represent the abnormality most often detected in prenatal studies, accounting for 30% to 50% of all structural anomalies present at birth. The most common disorders are urinary tract dilation, developmental variants, cystic kidney diseases, kidney tumors, and bladder defects. These anomalies can present in isolation or in association with various syndromes.

Sentinel lymph node biopsy after neoadjuvant chemotherapy in patients with operable breast cancer and positive axillary nodes at initial diagnosis.

Aim: To evaluate the utility of the sentinel lymph node biopsy (SLNB) in patients with operable breast cancer and positive axillary nodes at initial diagnosis treated with neoadjuvant chemotherapy (NAC).

Material And Methods: A prospective study was performed from January 2008 to December 2012 in 52 women, mean age 50.7 years, with infiltrating breast carcinoma T1-3, N1, M0 (1 bilateral, 7 multifocal) treated with epirubicin/cyclophosphamide, docetaxel and trastuzumab in Her2/neu-positive patients.

[Whole-body magnetic resonance imaging in a patient with an occult abdominal neuroblastoma and opsoclonus-myoclonus syndrome].

Opsoclonus-myoclonus syndrome is a rare neurological disorder. In children, the etiology varies, although it is a paraneoplastic manifestation (mainly of neuroblastoma) in 40% to 80% of cases. Whole-body MRI promises to be a powerful tool in the search for a possible primary tumor in this condition for which the diagnostic algorithm is yet to be established.

Sentinel lymph node biopsy in patients with operable breast cancer treated with neoadjuvant chemotherapy.

Aim: To evaluate the accuracy of sentinel lymph node biopsy (SLNB) in operable breast cancer patients treated with neoadjuvant chemotherapy (NAC).

Materials And Methods: Between January 2008-2011, 88 women, mean age 49.4 years, with infiltrating breast carcinoma, were studied prospectively.
