In November 1846, Henry Jacob Bigelow, a Boston surgeon, reported a breakthrough in the search for surgical anesthetics with the first uses of inhaled ether in 1846. This allowed patients to remain sedated during operations ranging from dental extraction to amputation.[8] "A patient has been rendered completely insensible during an amputation of the thigh, regain consciousness after a short interval," Bigelow wrote. "Other severe operations have been performed without the knowledge of the patients."
In April 2001, Druker et al. reported a targeted therapy for chronic myelogenous leukemia. Based on the knowledge that BCR-ABL, a constitutively activated tyrosine kinase, causes CML, the authors tested with success an inhibitor of this tyrosine kinase in patients who had failed first-line therapy. The finding helped begin the era of designing cancer drugs to target specific molecular abnormalities.[18]

xColorectal cancer (CRC) is common, affecting >40,000 people a year in the UK. Most cancers are sporadic but a few, such as those occurring at a younger age, have a clear genetic basis. Most are situated in the rectum or rectosigmoid and cause rectal bleeding, often with a looser or more frequent stool. Right-sided cancers typically result in anaemia, because the blood in the stool is occult and unnoticed by the patient. Almost all symptoms of malignancy can also be caused by benign disease. Diagnosis relies on luminal imaging, with colonoscopy being the gold standard.

Elsevier’s Medicine is a continually updated, evidence-based learning resource for trainees. It is an essential tool to help trainees achieve their postgraduate medical qualification, wherever you are in the world. It provides a concise overview of the latest medical knowledge and practice based upon the UK Core Medical Training curriculum, with each article written by invited qualified experts. Given its comprehensive coverage of internal medicine, this resource is also an ideal companion for GPs and consultants in the acute medicine setting.
The journal usually has the highest impact factor of the journals of internal medicine. According to the Journal Citation Reports, NEJM had a 2017 impact factor of 79.258,[24] ranking it first of 153 journals in the category "General & Internal Medicine".[25] It was the only journal in the category with an impact factor of more than 70. By comparison, the second and third ranked journals in the category (The Lancet and JAMA) had impact factors of 53.254 and 47.661 respectively.[26]
