Sentinel lymph node biopsy in papillary thyroid cancer: Accuracy and application in clinical practice.

Introduction: The presence of lymph nodes metastasis in papillary thyroid cancer (PTC) modifies the type of surgical resection as well as the indication of the treatment with I in the postoperative period. This therapeutic approach is based on the results of the diagnostic tests, like the cervical ultrasonography. Currently other methods of diagnostic are tested as selective sentinel lymph node biopsy (SLNB).

[Dementia with frontal lobe atrophy: clinical study from 18 patients with cognitive impairment and frontal lobe involvement detected by structural and functional neuroimaging].

Objective: To characterize clinically patients with cognitive impairment and frontal lobe degeneration at neuroimaging.

Patients And Methods: Patients diagnosed of dementia or mild neurocognitive impairment by DSM IV criteria and neuropsychological tests with frontal lobe atrophy and hipoperfusion detected by computed tomography and single photon emission computed tomography.

Results: 18 patients, 5:1 on behalf of women; mean age at onset, 74 years; hereditary for dementia, 38%; mean duration of illness at first testing, 2 years; the most common initial symptoms, memory loss.
