The AAN Practice Parameter by Moxley et al. notes that class I trials in Duchenne dystrophy studying daily prednisone 0.75 mg/kg or deflazacort 0.9 mg/kg provide evidence of sustained improvement in strength and function. The Practice Parameter supports a recommendation of offering corticosteroid treatment to patients but with a balanced discussion of potential risks.

Military service and amyotrophic lateral sclerosis (ALS)
Weisskopf et al. prospectively studied over 400,000 US men and found that those who served in the military had a significantly increased ALS mortality. Veterans in this cohort had served in World War II, Korea, or Vietnam, but not in the Gulf War.

The accompanying editorial by Beghi and Morrison notes that two epidemiologic studies in 2003 showed a twofold increased incidence of ALS in Gulf War veterans. The Weisskopf results argue against the role of unknown environmental factors specific to the Gulf War. Men who served in the military throughout the twentieth century may have been exposed to toxic agents like N,N-diethyl-m-toluamide, various infections, aerosolized lead, or other chemicals as well as traumatic injury, manual work, and strenuous physical activity. Importantly, a network of population-based national and regional registries of ALS (25 million target population) is being implemented in Europe and may provide answers concerning environmental risk factors in ALS.

Hippocampal damage in newly diagnosed focal epilepsy
Salmenperä et al. showed that 8% of newly diagnosed patients with focal epilepsy had hippocampal (HC) damage at the time of the diagnosis and 13% of patients developed HC volume decrease in MRI during the first years of prospective follow-up.

Chemotherapy for primary CNS lymphoma
In a prospective study, Omuro et al. found response rates of 82% using thiotepa and procarbazine with lower than usual doses of methotrexate (1 g/m2). This regimen may be useful for patients unable to tolerate higher doses of methotrexate. Thiotepa and procarbazine merit further evaluation in prospective PCNSL trials.

A prospective longitudinal study of hallucinations and sleep disorders in PD
Goetz et al. assessed the relationship of hallucinations to sleep disorders in Parkinson disease. Hallucination prevalence and severity increased over time, whereas sleep disorders fluctuated widely among and within patients, with no evidence of progression in severity. Sleep fragmentation and vivid dreams/nightmares among non-hallucinators did not predict future development of hallucinations. Though often considered as associated behaviors, hallucinations and global sleep disorders follow very different patterns of progression in PD, and sleep alterations are not harbingers of hallucinations.

tPA by telephone
Frey et al. demonstrated equivalent results in the use of tPA between 73 stroke patients treated in house and 53 patients treated by a telephone-supported network of emergency departments and paramedics.

Race and temporal lobe epilepsy surgery
Burneo et al. evaluated the rates of epilepsy surgery on 70 Caucasians and African Americans in a cohort of patients with intractable temporal lobe epilepsy associated with mesial temporal lobe sclerosis. After controlling for multiple variables, African Americans were 60% less likely to receive surgery than Caucasians (OR = 0.3, 95% CI 0.2 to 0.8), suggesting disparities in the use of surgery among Americans.
see page 50
The accompanying editorial by Jennifer Griggs and Jerome Engel notes that both patient and physician factors contribute to disparities in the use of a procedure. Patient factors include preferences for surgical vs medical management, attitudes towards the illness, and trust in physicians and the health care system. Blacks have a preference for non-surgical management of chronic problems, even those that lead to "Assuming that the difference in the rate of seizure surgery is due to underuse among blacks (rather than overuse among whites), efforts to address such disparities are clearly important in narrowing the gap in quality of care." disability. Moreover, in a recent study of patient perceptions of epilepsy surgery, participants in the study (including African Americans) overestimated the risks and underestimated the benefits of epilepsy surgery. Additionally, African Americans also expressed mistrust of physicians. Attributing differences in treatment to patient preferences and perceptions would relieve physicians and the health care system of responsibility. However, treatment preferences are formed by experiences with the health care system and the information provided about the treatment. Provision of accurate information may eliminate racial differences in attitudes towards a procedure.
