5-HT4 receptor agonists show different efficacies. Motilin receptor activation has greater potential to increase gastric emptying, whereas ghrelin and D2 receptor antagonism have no direct activity. Drugs stimulating human gastric motility directly can act regardless of disease mechanisms, whereas drugs without direct activity but an ability to block nausea/vomiting may be effective only if these symptoms exist.
Regarding the three methods tested, the new prototype FAPC device allowed hemostasis of notable bleeding from a major vessel even more quickly than forceps coagulation of a bleeding side branch. More studies are needed to further explore this potentially very valuable tool.
Subcutaneous mastectomy and axillary dissection combined with immediate reconstruction was used to treat primary breast cancer in a consecutive series of 111 patients. Local recurrence occurred in 19 patients (17 per cent) during a mean follow-up of 30 (range 6-60) months. Complete control of local disease was achieved in all patients except one, who had terminal disease. Prophylactic radiotherapy was avoided for 83 per cent of patients, and good cosmetic results were obtained in 89 per cent. These results support the use of this technique in the treatment of early breast cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
