Because the American Academy of Neurology (AAN) exists to represent the views and needs of neurologists, a mailed survey to a randomly selected sample of 520 US-based, board-certified or board-eligible neurologist members was conducted in early 1995 to determine their attitudes in four key changing areas of the US health care system: (1) provision of neurologic care, (2) neurology workforce, (3) academic research, industry sponsorship, and pharmaceutical issues, and (4) health care delivery systems issues. Frequency distributions of degree of agreement and disagreement with 40 statements regarding issues in these four areas were tabulated for the entire group of 430 respondents (response rate = 83%). Associations between these attitudes and six demographic and practice variables (age, gender, board certification, practice type, degree of managed care, and geographical region) were evaluated in an exploratory analysis. ⋯ With respect to many of the current mechanisms for health care cost containment, respondents indicate they have little confidence that these strategies are in the best interests of patients or physicians. The survey results confirm that there is no consensus among US neurologists on how to improve today's health care delivery system, and the results suggest that certain attitudes are related to neurologists' demographic and practice characteristics. Since today's health care market is volatile, regular assessments of neurologists' attitudes will be needed to assure that their views are understood and clearly represented by the AAN.

A new generation of Atraumatic (blunt tipped) needles now exists in addition to the traditional Quincke (cutting tip) needles for LP. We wished to identify the optimal size and type of needle that should be used for this technique. Requirements include rapid and accurate transduction of CSF pressure and adequate flow rate for CSF collection purposes while minimizing headache and other neurologic sequelae. ⋯ Some of the 22-gauge Atraumatic needles rapidly measured CSF pressure, but their flow rates were only suitable for small volume CSF collection. There is extensive literature to support that neurologic sequelae are reduced using Atraumatic needles. Diagnostic LP can be easily and accurately performed by using a large Atraumatic needle with the potential for considerable reduction in post-LP headache and related neurologic sequelae.

Phenobarbital, diazepam, lorazepam, and phenytoin are all currently used for the treatment of acute seizures, including status epilepticus. None of these drugs is considered ideal. Fosphenytoin is a new phenytoin prodrug that fulfills many of the properties of an ideal anticonvulsant drug. ⋯ The most common systemic adverse events reported--somnolence, nystagmus, dizziness, and ataxia--are side effects commonly seen with phenytoin and tended to be mild. Preexisting seizure disorders remained stable. Combination treatment with i.v. diazepam or lorazepam to attain rapid seizure control and i.m. fosphenytoin to maintain the anticonvulsant effect theoretically offers many advantages for control of acute seizures and should be studied.

We analyzed our experience with cough, exertional, and vascular sexual headaches, evaluated the interrelationships among them, and examined the possible symptomatic cases. Seventy-two patients consulted us because of headaches precipitated by coughing (n = 30), physical exercise (n = 28), or sexual excitement (n = 14). Thirty (42%) were symptomatic. ⋯ Benign cough headache began significantly later, 43 years on average, than benign exertional headache. By contrast, our findings suggest that there is a close relationship between benign exertional headache and benign vascular sexual headache. We conclude that benign and symptomatic cough headaches are different from both benign and symptomatic exertional and sexual headaches.

Fosphenytoin sodium, a phosphate ester prodrug of phenytoin, was developed as a replacement for parenteral phenytoin sodium. Unlike phenytoin, fosphenytoin is freely soluble in aqueous solutions, including standard i.v. solutions, and is rapidly absorbed by the i.m. route. ⋯ Fosphenytoin has fewer local adverse effects (e.g., pain, burning, and itching at the injection site) after i.m. or i.v. administration than parenteral phenytoin. Systemic effects related to the CNS are similar for both preparations, but transient paresthesias are more common with fosphenytoin.
