Debate persists regarding whether cricothyrotomy is best performed using the Seldinger or conventional surgical technique (see JWEM Feb 2000, p. 11, and J Emerg Med 1999; 17:957). Investigators in Vienna provided a 60-minute training session consisting of lectures, slides, and the tools for each method to 20 ICU residents and fellows not experienced in cricothyrotomy. Each physician then perfor...
abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
The aim of this study was to investigate the responses of creatine kinase (CK) and lactate dehydrogenase (LDH) after performing different resistance and aerobic exercise protocols. Twelve recreationally trained men (age, 23.2 ± 5.6 years; body mass, 84.3 ± 9.3 kg; body height, 178.9 ± 4.5 cm; and BMI, 26.3 ± 2.3 kg·m2) volunteered to participate in this study. All subjects were randomly assigne...
Purpose: To examine the effects of commercially available sports beverages with various components on substrate metabolism and subsequent performance. Methods: Two studies were conducted in a double-blinded, counterbalanced manner. Study I was designed to determine the glycemic index, while study II determined the utilization of substrates and subsequent exercise performance. Ten healthy male p...
BACKGROUND Growing evidence implicates an overactivity of the cerebellum in the pathophysiology of essential tremor. In a small series of patients, we explored the acute effects and therapeutic possibilities of low-frequency repetitive transcranial magnetic stimulation (rTMS) of the cerebellum in patients with essential tremor in a double-blind, crossover, placebo-controlled design. METHODS T...
BACKGROUND Although the effects of gambling on cardiovascular parameters have been documented, no data exists describing the effect of gambling on stress hormone secretion. Our study investigated the effect of gambling on heart rate and salivary cortisol in a casino environment. METHODS Ten male gamblers participated in both an experimental and control session. In the experimental session, ga...
Background and Objective: The proportional practice protocol is an important issue for middle-aged women to start a health and energetic life style. Aerobic training is proposed as the first and best method of practice for all individuals. However, this protocol is not without damage, because this method like other methods can lead to some cellular disorders, especially muscle cell disorde...
PURPOSE To investigate patterns of functional magnetic resonance imaging (fMRI) activation during sentence reading before and after wearing color-tinted lenses. METHODS A total of 15 Meares-Irlen syndrome patients with a mean age of 23.4 years (range, 13 to 42 years) with no history of neurological or psychiatric disorders were scanned using a 3T MR scanner (Siemens, Tim-Trio, Germany). Each ...
OBJECTIVE To assess the ability of otolaryngology residents to rate the hypernasal resonance of patients with velopharyngeal dysfunction. We hypothesize that experience (postgraduate year [PGY] level) and training will result in improved ratings of speech samples. STUDY DESIGN Prospective cohort study. SETTING Otolaryngology training programs at 2 academic medical centers. SUBJECTS AND ME...
