Levothyroxine-induced serum free thyroxine response following radioactive iodine administration in patients thyroidectomized for differentiated thyroid cancer: A randomized controlled trial.

Purpose: Patients undergoing thyroidectomy for differentiated thyroid cancer (DTC) may require 131-radioactive iodine (RAI) administration for remnant ablation or disease treatment. After ingestion, RAI resides within the gastrointestinal tract potentially leading to mucosal damage and abnormalities in the absorption of levothyroxine (LT4). The aim of this study was to evaluate whether serum FT4 peak, induced by a LT4 challenge, changes according to the LT4 formulation (solid or liquid) in both RAI and non-RAI-treated DTC patients.

[Vaping-induced lung injury].

Vaping is considered to be the inhalation of aerosols generated by heating liquids. There are devices freely marketed for vaping, with electronic cigarettes being the most common. These products are associated with the appearance of lung injury, either vaping-induced lung injury (VAPI), or lung injury associated with vaping and electronic cigarettes (EVALI).

[COVID-19 experience in a private institution in Buenos Aires during the first month of the pandemic: 26 cases].

The first case of coronavirus (COVID-19) infection in Argentina was reported in Buenos Aires on March 3rd, 2020, in a patient who arrived from Milan. The aim of this study is to describe the clinical characteristics and course of illness of patients infected with Covid-19 that were hospitalized in a private clinical setting during March 2020. Sixty three patients suspected of COVID-19 infection, were admitted to our hospital during March 2020.

Comparison of Procalcitonin Assays on KRYPTOR and LIAISON XL Analyzers.

Our laboratory performs procalcitonin (PCT) assays on a Brahms KRYPTOR analyzer with the Brahms PCT sensitive Kryptor kit. In this study, we wanted to compare the assays obtained in this way with the ones performed on the LIAISON XL. From January to May 2017, 171 samples were analyzed, of which 65 from female patients (age: 22-98 years) and 106 from male patients (age: 16-97 years).
