BACKGROUND Achievement of complete cavotricuspid isthmus (CTI) conduction block reduces typical atrial flutter recurrences after ablation. The lack of increase in the His-to-coronary sinus ostium atrial interval during incremental pacing (IP) from the low lateral right atrium may distinguish slow conduction from complete CTI conduction block. METHODS AND RESULTS Sixty-six consecutive patients...
BACKGROUND/AIM Benign paroxysmal positional vertigo is one of the most frequent peripheral vestibular system disorders. The aim of this study was to examine the efficacy of the Epley maneuver in treating benign paroxysmal positional vertigo of the posterior semicircular canal (p-BPPV) and to discover possible causes of failure. METHODS This prospective study included 75 patients. In all the c...
purpose : to report a case of purtscher retinopathy associated with valsalva retinopathy after car accident methods : a 54-year-old man presented with a sudden visual loss in his left eye after car accident. fundus examination of the left eye showed cotton-wool spots and retinal hemorrhages in the posterior pole associated with subhyaloid hemorrhage in macula. results : fundus examination showe...
Practical aspects of motion generation and control for parking a nonholonomic autonomous vehicle are considered. An iterative algorithm for the parallel parking maneuver is proposed. It is based on ultra-sonic range data processing. To control the steering angle and longitudinal velocity of the vehicle during the parking maneuver, sinusoidal reference functions are used. To prevent collisions, ...
OBJECTIVE The aim of this study was to evaluate the negative effects of the Pringle maneuver on pancreatic tissue with respect to the time of performing the maneuver. Moreover, the efficacy of octreotide therapy on pancreatic changes at the time of the Pringle maneuver was assessed. ANIMALS Fifty male Wistar Albino rats were randomized into 5 groups. DESIGN The groups were formed as follows...
PURPOSE To investigate lamina cribrosa (LC) displacement during the Valsalva maneuver in young healthy eyes using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT). METHODS Forty-eight eyes of 48 young healthy volunteers (age range: 20-34 years) underwent intraocular pressure (IOP) measurement by Goldmann applanation tonometry as well as Cirrus HD-OCT scans be...
UNLABELLED Benign paroxysmal positional vertigo (BPPV) may compromise the balance of elderly subjects. OBJECTIVE To observe the effects of the Epley maneuver in elderly subjects with BPPV and assess clinical and functional aspects of body balance. METHOD This is a prospective clinical study. Patients diagnosed with BPPV (Dix-Hallpike test) were submitted to the Timed Up & Go (TUG) test, the...
