In vitro study of ingested coins: leave them or retrieve them?

Background: Objects and notably coins are frequently swallowed by children 3 to 5 years old. Precisely how they should be managed after passing the gastroesophageal junction without causing symptoms remains controversial. This study was performed to assess dissolution of specific metals from coins immersed in simulated gastric juice.

Morbidity of breast cancer patients following complete axillary dissection or sentinel node biopsy only: a comparative evaluation.

Introduction: The usefulness of routine axillary dissection (AD) at levels I-II in breast cancer patients has been questioned for years because of the high postoperative morbidity in the shoulder and arm region, and the increasing number of patients with negative nodes. Sentinel node biopsy (SNB) was hoped both to reduce morbidity and to improve the reliability of staging. This study was designed to provide more evidence in this matter by comparing the follow-up data of patients with AD and those with SNB only.
