Randomized Controlled Trial Multicenter Study
Maintenance pemetrexed plus best supportive care versus placebo plus best supportive care for non-small-cell lung cancer: a randomised, double-blind, phase 3 study.
Several studies have shown the efficacy, tolerability, and ease of administration of pemetrexed-an antifolate antineoplastic agent-in patients with advanced non-small-cell lung cancer. We assessed pemetrexed as maintenance therapy in patients with this disease. ⋯ Eli Lilly.

Tetralogy of Fallot is the most common form of cyanotic congenital heart disease, and one of the first to be successfully repaired by congenital heart surgeons. Since the first procedures in the 1950s, advances in the diagnosis, perioperative and surgical treatment, and postoperative care have been such that almost all those born with tetralogy of Fallot can now expect to survive to adulthood. The startling improvement in outcomes for babies born with congenital heart disease in general-and for those with tetralogy of Fallot in particular-is one of the success stories of modern medicine. ⋯ Consequently, new issues have emerged, ranging from hitherto unpredicted medical complications to issues with training for caregivers and resource allocation for this population of survivors. Therefore, evolution of treatment, recognition of late complications, research on disease mechanisms and therapies-with feedback to changes in care of affected children born nowadays-are templates on which the timely discussion of organisation of care of those affected by congenital heart diseases from the fetus to the elderly can be based. Here, we focus on new developments in the understanding of the causes, diagnosis, early treatment, and late outcomes of tetralogy of Fallot, emphasising the continuum of multidisciplinary care that is necessary for best possible lifelong treatment of the 1% of the population born with congenital heart diseases.

Peptic ulcer disease had a tremendous effect on morbidity and mortality until the last decades of the 20th century, when epidemiological trends started to point to an impressive fall in its incidence. Two important developments are associated with the decrease in rates of peptic ulcer disease: the discovery of effective and potent acid suppressants, and of Helicobacter pylori. With the discovery of H pylori infection, the causes, pathogenesis, and treatment of peptic ulcer disease have been rewritten. ⋯ Despite substantial advances, this disease remains an important clinical problem, largely because of the increasingly widespread use of non-steroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin. We discuss the role of these agents in the causes of ulcer disease and therapeutic and preventive strategies for drug-induced ulcers. The rare but increasingly problematic H pylori-negative NSAID-negative ulcer is also examined.
