A profile of the medically uninsured in Georgia.

The provision of health care to the growing number of persons uninsured against medical expenses affects Georgia doctors, hospitals, and state and local government at all levels. While much is known nationally about the uninsured, there are no good data about this group in Georgia. This study uses U.S. Census Bureau data to provide a demographic profile of Georgians who lack health insurance and to identify groups at particular risk for being uninsured. Approximately 950,000 (17.7%) of non-elderly Georgia residents are uninsured, compared to 37 million (17.6%) in the U.S. as a whole. As is true generally in the U.S., those in Georgia who are poor, young, non-white, and in families with a female head are at greatest risk. Of particular note are the poor in Georgia with incomes from 50% to 100% of the federal poverty level (55.2% uninsured). This population deserves the special attention of all involved in finding a solution to this problem.

Local anesthetic properties of opioids and phencyclidines: interaction with the voltage-dependent, batrachotoxin binding site in sodium channels.

[3H]Batrachotoxinin-A 20-alpha-benzoate ([3H]BTX-B) binds specifically and with high affinity (Kd = 30 nM) to a site on voltage-dependent Na+ channels. Compounds with local anesthetic activity inhibit the binding of [3H]BTX-B by a mutually exclusive, allosteric mechanism. The potential local anesthetic potency of a series of 23 opioids and phencyclidine-like compounds has been estimated by their inhibition of [3H]BTX-B binding to Na+ channels in a preparation of synaptoneurosomes from guinea pig cerebral cortex. The potency of these compounds were also tested as inhibitors of the specific binding of [3H]phencyclidine ([3H]PCP) to a high affinity site on rat brain membranes. Opioids such as morphine and codeine show little affinity for the [3H]BTX-B binding site or for the [3H]PCP binding site. Other analgesics, many of the PCP-like compounds and dioxadrol derivatives are potent versus [3H]BTX-B binding and display both stereospecificity and high affinity towards the PCP-binding site. However, there was no correlation between local anesthetic potency assessed as antagonism of [3H]BTX-B binding and affinity towards the PCP site. Five classical local anesthetics had no affinity for the PCP-site, but did displace [3H]BTX-B from its binding site.

Using workshops to implement supervision.

Clinical supervision is both topical and novel among many practice disciplines so it is important to consider how to take such an important initiative forward. This article describes a series of workshops designed to achieve this aim. The article focuses on the participants' perceptions of clinical supervision and its relevance to their practice environment. The authors also suggest ways to assist clinical staff further in this area.

The homeless mentally ill.

All countries in the West experience the phenomenon of what has been called 'the homeless mentally ill'. There seems to be no simple solution but a challenge is presented to all nurses who can play a significant role. This is an abridged version of a paper delivered in Tel Aviv by two American nurses.
