[Evaluation of the sentinel lymph node in T1-T2 papillary thyroid cancer: a preliminary study].

Objective: Sentinel lymph node biopsy in differentiated thyroid cancer may benefit patients with no clinically affected lymph nodes and can avoid a prophylactic or staging lymphadenectomy.

Methods: A prospective study was conducted on 23 consecutive patients with papillary thyroid carcinoma with no clinical or radiological suspicion of lymph involvement. After injecting methylene blue around the tumour during the biopsy of the identified sentinel lymph node, a total thyroidectomy and a via-b ipsilateral lymphadenectomy was performed for the later study with cytokeratin.

Course of metabolic syndrome following the biliopancreatic diversion of Larrad.

Background: The authors assessed the effect of Larrad's biliopancreatic diversion (BPD) on the main components of the metabolic syndrome.

Patients And Methods: Plasma concentrations of glucose, insulin, total cholesterol (TC), HDL and LDL cholesterol, triglycerides, LDL/HDL and TC/HDL ratios, and blood pressure and body weight were retrospectively evaluated in 40 patients 3-6, 12, 24 and 60 months after undergoing BPD for morbid obesity with metabolic syndrome.

Results: 3-6 months after BPD, glycemia and insulinemia had normalized in 97.
