High parathyroid hormone levels after parathyroidectomy for parathyroid adenoma are not related to the cellularity of the remaining glands.

Background: Patients with primary hyperparathyroidism (PHPT) treated surgically occasionally have normalized calcium, but persistently high parathyroid hormone (PTH). We hypothesized that a possible explanation for this phenomenon is an underlying hyperplasia rather than adenoma.

Methods: Retrospective cohort of patients who underwent parathyroidectomy for PHPT with biopsy of a normal-appearing parathyroid gland were included.

Impact of Antibiotic Therapy during Bedside Percutaneous Tracheotomy procedure in an Intensive Care.

Introduction: Percutaneous bedside tracheostomy (PBT) is a frequently done procedure in the intensive care unit (ICU). The rate of infectious complications and efficacy of perioperative therapy in reducing infections after PBT is currently unknown.

Methods: All demographic, clinical and microbiologic data was retrospectively collected from 110 cases of PBT performed in our ICU from 2006 to 2012.
