[Liver transplantation: development, learning curve and results after the first 300 cases].

Background: Liver transplantation (LT) is an option for people with liver failure who cannot be cured with other therapies and for some people with liver cancer.

Aim: To describe, and analyze the first 300 LT clinical results, and to establish our learning curve.

Material And Methods: Retrospective cohort study with data obtained from a prospectively collected LT Program database.

Autologous versus prosthetic reconstruction for women with breast cancer who will undergo post-reconstruction radiotherapy.

Introduction: Radiotherapy is frequently used after breast reconstruction in patients with locally advanced breast cancer or metastases in axillary lymph nodes. However, there might be differences between autologous and prosthetic reconstruction in terms of effectiveness and safety of post-reconstruction radiotherapy.

Methods: To answer this question we searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others.

Is a ureteral stent required after use of ureteral access sheath in presented patients who undergo flexible ureteroscopy?

Introduction: Use of a ureteral access sheath (UAS) within flexible ureteroscopy (fURS) for the management of kidney and ureteral stones has shown improvements in its effectiveness, but it is also associated with increased risk of ureteral injury. Use of ureteral stent (US) after fURS is recommended by some authors, because of its role in reducing postoperative pain and preventing complications. Our objective is to determine if postoperative stenting is necessary in pre-stented patients that underwent fURS using UAS.
