    Notes: Abstract We investigated the mechanisms of stress-induced alterations in adrenocorticotrophin (ACTH) release. Tandem parachutists received either a placebo or the β-adrenoceptor antagonist propranolol prior to a first time parachute jump. Blood samples were drawn 4 h before, immediately after, and 1 h after the jump. Cortisol and catecholamine concentrations displayed a significant stress-induced increase in both groups. The ACTH plasma concentrations significantly increased in the placebo and the propranolol group, with significantly more pronounced changes in the propranolol-treated subjects compared to the placebo group. These data demonstrated a stress-induced increase of ACTH plasma concentrations in humans that was enhanced by β-blockade.

    Notes: Abstract Objective: To estimate costs and benefits of vaccinating young homosexual men against hepatitis A. Design and setting: A decision-analytic model was used to assess vaccination from the societal perspective. Effects of vaccination at age 20 were modeled through each person's lifetime, with costs discounted at 3% annually. Intervention: Two doses of formalin-inactivated vaccine (Havrix, Smithkline Beecham Pharmaceuticals) administered by intramuscular injection 6–12 months apart. Results: Vaccination of 10,000 men would cost $959,000. Over the lifetimes of cohort members, hepatitis A-related hospitalizations would decline from 366 to 76, and treatment costs would decline from $2,577,000 to $363,000. Treatment cost reduction would fully offset vaccination costs within 10 years. Productivity losses associated with hepatitis A morbidity, primarily work absenteeism, would decline by $5,231,000. Vaccination would prevent an estimated 8.6 premature deaths, saving 213 life-years and $2,836,000 in mortality-related productivity losses. Results are only modestly affected when model assumptions are varied within plausible ranges. Conclusions: Hepatitis A vaccine provides improved patient outcomes and cost reduction. From a societal perspective, vaccination provides $10.72 in economic benefits for every $1 spent on vaccination. Physicians should counsel homosexual men to be vaccinated against hepatitis A. Health insurers would find it in their own financial interest to cover vaccination.

    Notes: Abstract Very weak and noisy trigeminal somatosensory evoked potentials (TSEPs) are considered, which are successfully evoked by electrical stimulation of the trigeminal nerve of 15 patients with endosseous oral implants. As TSEP analysis provides an objective means of assessing neuronal function, it is considered to be a promising tool for investigating tactile sensation through anchoring implants in bone. For this purpose, a study of TSEP signals acquired from patients with endosseous oral implants has been carried out. Since TSEPs are severely contaminated by background ongoing electrical activities of the brain, a methodology is developed for statistically detecting the transient signal (TSEP) in the biological noise (EEG). For nine out of 15 patients, transient signals are detected in the background EEG activity. The TSEPs of these nine patients are subjected to further analysis. A multichannel singular value decomposition (SVD)-based filtering method is applied which successfully separates out the most energetic TSEPs from the background EEG, thereby increasing significantly the SNR of the recorded signals and improving extraction of the characteristic components of the TSEPs. It is shown that the most prominent feature of the TSEP signals for patients with endosseous oral implants is a wave with peak latency between 9 and 15 ms, generally followed by a wave between 25 and 28 ms or 34 and 38 ms for the specific cortical response areas.
