Relevance of Sentinel Nodes in Atypical Territories in Surgically Treated Patients With T1-2N0 Oral Squamous Cell Carcinoma.

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).

Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

One-step nucleic acid amplification for intraoperative analysis of sentinel lymph node in papillary thyroid carcinoma.

Objective Lymphadenectomy in papillary thyroid carcinoma (PTC) is controversial. It is indicated whenever metastases have been proven before or during surgery and as a prophylactic treatment in high-risk patients. However, 30-50% of cN0 patients become pN1 postoperatively.

Pediatric Nuclear Medicine and its Development as a Specialty.

Pediatric Nuclear Medicine (PNM) offers to the pediatrician noninvasive procedures, with high clinical impact and low dosimetry. New techniques have been adapted to children, diminishing doses, always looking for less dosimetry, higher sensitivity and higher resolution images. PNM is and will remain a minority subspecialty, but highly complex for general NM physicians due to the different diagnostics in children and due to the higher technical complexity of the examinations.

SPECT/CT sentinel lymph node identification in papillary thyroid cancer: lymphatic staging and surgical management improvement.

Purpose: Lymphadenectomy in papillary thyroid carcinoma (PTC) continues to be controversial. A better staging method is needed to provide adequate individual surgical treatment. SPECT/CT lymphoscintigraphy and sentinel lymph node (SLN) biopsy may improve lymphatic staging and surgical treatment.

[Differentiated thyroid carcinoma in children: study of 80 cases].

Background And Objective: The objective was to analyze the clinical profile of Differentiated Thyroid Carcinoma in children (DTC) and the predisposing factors to suffering the disease.

Material And Method: Eighty children with DTC were studied retrospectively. They all underwent total/near total thyroidectomy and 75 cases underwent ablative iodine therapy.

[Differential diagnosis of parkinsonism using dopamine transporters brain SPECT].

Background And Objective: Parkinsonism is a group of neurological disorders characterized by extrapiramidal signs. Often, the differential diagnosis between parkinsonism, essential tremor and drug-induced parkinsonism is difficult. The aim of the study was to evaluate the utility of (123I)-FP-CIT SPECT in patients with movement disorders.
