Internal Dose Assessment of New 177Lu-Radiopharmaceuticals and Its Role in Radiation Protection of Patients.

Since 2006, CNEA has been conducting studies on the production, labeling, quality control and NIH mice biodistribution of several radiopharmaceuticals based on 177Lu locally produced. In order to contribute to ensuring the radiation protection of patients, the Internal Dosimetry Laboratory of the ARN has been complementing the preclinical study performing a dose assessment. This assessment included: the activity biodistribution analysis in NIH mice, the estimation of the absorbed dose, the extrapolation of the results to humans, the identification of healthy organs with high risk and the estimation of the maximum activity that can be administered to a patient without exceeding the threshold of radiotoxicity in healthy organs.

Extrahepatic portal vein aneurysm after liver transplantation in a child: case report.

Portal vein aneurysms are very rare and represent <3% of all venous aneurysms. They can be congenital or acquired. Most patients do not have liver disease at diagnosis.

Early postoperative complications of deep lamellar endothelial keratoplasty.

Purpose: To report and discuss the early postoperative complications of deep lamellar endothelial keratoplasty (DLEK).

Methods: The records of the first 44 patients who underwent DLEK by 1 surgeon were reviewed. Complications occurring between the first day and eighth week after surgery were recorded.

Five-millimeter-incision deep lamellar endothelial keratoplasty: one-year results.

Purpose: To evaluate visual acuity, topography, and endothelial cell density 1 year after deep lamellar endothelial keratoplasty (DLEK) for endothelial dysfunction.

Methods: This is a prospective, comparative, interventional case series. Thirty-five eyes of 35 patients who had undergone DLEK with a 5-mm incision and had a minimum of 1-year follow-up were included.
