The HER2 gene or c-erb B2 or neu is amplified in 15-25% of breast cancers. This amplification is associated with an aggressive course of disease. The trastuzumab is a monoclonal antibody targeting the extracellular domain of HER2. This is the first targeted molecule designed to treat breast cancer. In the firstline metastatic disease, trastuzumab in combination with chemotherapy significantly improved survival of patients with HER2-positive disease. In the adjuvant setting, trastuzumab has been evaluated in several randomized trials. ⋯ In the contemporary medical literature, several strong arguments confirm the benefit in survival of trastuzumab administered concomitantly with a taxane-based chemotherapy and with concurrent radiotherapy, and for a period of 1year. Trastuzumab was well tolerated. Only 2% or less of patients experienced a serious cardiac toxicity, but it was reversible in most of the time.

Multicenter Study
[Cost awareness at emergencies: multicentric survey among prescribers].
Regular increasing of health-care expense brought about the development of medical implication in prescription control and the will to give more responsibility to prescribers. Emergency departments account for a large part of hospital expenses. This study was carried out to evaluate cost awareness among French emergency physicians. ⋯ Physicians had a poor understanding of prescription costs at the emergencies, especially regarding high-cost drugs. Much progress is required to integrate the cost-containment problem in daily prescriptions at the emergency department.

Opioid maintenance treatments (OMT) reduce illicit opiate use and its associated risks. They are often prescribed on a long-term basis. Physiological changes induced by long-term OMT may cause hyperalgesia and cross-tolerance to opioid agonists, which suggests that the dosage of analgesic treatment should be modified in cases of acute pain, especially when an opioid-based analgesia is required. ⋯ With buprenorphine, non-opioid analgesics should be introduced first, if possible. If this strategy is inefficient or contraindicated, a temporary or definitive switch to methadone should be considered. In the case of methadone-based OMT, opioid analgesics should be added directly and the dosage should be adapted according to the level of pain reported by the patient.
