VITAMIN D DEFICIENCY DOES NOT AFFECT THE LIKELIHOOD OF PRESURGICAL LOCALIZATION IN ASYMPTOMATIC PRIMARY HYPERPARATHYROIDISM.

Objective: Vitamin D deficiency (VDD) was previously associated with larger adenoma size in primary hyperparathyroidism (PHPT), but this topic was not addressed in patients with the mild/asymptomatic form of the disease (aPHPT).

Methods: We retrospectively retrieved from our series of patients affected by PHPT, 96 consecutive subjects with aPHPT in whom 25-hydroxyvitamin D (25OHD) levels had been assayed and compared those results with localizing imaging studies.

Results: Twenty-five of 96 patients had VDD (25OHD <20 ng/mL), but positive ultrasound and scintigraphic studies were not different between patients with and without VDD (52.

Not palpable? Role of radio-guided video-assisted thoracic surgery for nonpalpable solitary pulmonary nodules.

Purpose: This study aimed to evaluate the effectiveness of radio-guided localization for thoracoscopic resection of small nonpalpable lung nodules.

Methods: Nineteen patients with a solitary nodule were enrolled. Inclusion criteria were maximum nodule diameter <15 mm, distance from nearest pleural surface of 20-40 mm, nonsolid or partly solid nodule, and/or posterior location.
