Hyperprolactinemia: etiology, diagnosis, and management.
Hyperprolactinemia is the most common endocrine disorder of the hypothalamic-pituitary axis. A prolactinoma is the most common cause of chronic hyperprolactinemia once pregnancy, primary hypothyroidism, and drugs that elevate serum prolactin levels have been excluded. Patients can present with hypogonadism, infertility, galactorrhea, osteopenia, and mass effects of the tumor. When hyperprolactinemia is confirmed, a cause for the disorder needs to be sought. This involves a careful history and examination, followed by laboratory tests and diagnostic imaging of the sella turcica. The goals of treatment are to normalize prolactin levels, restore gonadal function, and reduce the effects of chronic hyperprolactinemia. Dopamine agonists are the treatment of choice for the majority of patients. Transsphenoidal surgery is usually reserved for patients who are intolerant of or resistant to dopamine agonists or when hyperprolactinemia is caused by non-prolactin-secreting tumors compressing the pituitary stalk. Cabergoline has been shown to be more effective and better tolerated than bromocriptine. However, there are more data on the safety of the latter drug during pregnancy and bromocriptine, therefore, remains the treatment of choice in hyperprolactinemic women wishing to conceive.

Brasofensine treatment for Parkinson's disease in combination with levodopa/carbidopa.
OBJECTIVE: To investigate the safety, tolerability, pharmacokinetic, and pharmacodynamic properties of the dopamine transporter antagonist brasofensine (BMS-204756) in patients with Parkinson's disease receiving levodopa/carbidopa treatment. METHODS: A 4-period crossover study was performed in 8 men (mean age 66 y) with moderate Parkinson's disease (Hoehn-Yahr stage II-IV). A dose escalation study was used in which each patient was given a single oral dose of brasofensine 0.5, 1, 2, or 4 mg, which was coadministered with the patient's usual dose of levodopa/carbidopa. RESULTS: The maximum concentration (Cmax) values of brasofensine observed in plasma after oral administration were 0.35, 0.82, 2.14, and 3.27 ng/mL for the 0.5-, 1-, 2-, and 4-mg doses, respectively; these concentrations occurred 4 hours (time to Cmax) after administration in all cases. Exposure to brasofensine (based on AUC0-infinity) increased at a rate greater than proportional to dose. Based on the motor performance subscale of the Unified Parkinson's Disease Rating Scale, no change in patient disability was observed at any dose level. CONCLUSIONS: Brasofensine was safe and well tolerated in the patient cohort studied at daily doses of up to 4 mg. Adverse events were generally mild in intensity, and included headache, insomnia, phlebitis, dizziness, ecchymosis, and vomiting.

Government policy and older people.
Older people are the main users of health and social care services, but services have not always adequately addressed need (Department of Health, 2001). The past 50 years have witnessed many changes and reforms in health and the social welfare state that have directly affected older people and the level and type of help and support they can expect from the state. Nurses need to understand these changes, as the implications of policy development will have a direct impact on the people we are working with. Nurses also have a part to play in shaping and informing policy development.
