[Esophageal digital videofluorography with water siphon test in the post-operative evaluation of the anti-reflux laparoscopic surgery].

2004

Background: In recent years digital videoefluorography (VFG) with water siphon test (WST) has been proposed just for diagnosing biatal bernia and/or gastroesophageal reflux. Patients and Methods: Fifteen patients undergone Laparoscopic Nissen (LN) for complicated GFRD associated to biatal bernia, were referred for VFG and WST in order to evaluate the functional results of surgery. At one- month videofluorographic control thirteen patients had just a minimal prolonged esophageal transit time hut only six of these had an early postoperative dysphagia, whereas at six montJh control the prolonged esophageal transit time was present in three patients two of which complained a very light dysphagi…

Monocular Versus Binocular Calibrations in Evaluating Fixation Disparity With a Video-Based Eye-Tracker

2015

When measuring fixation disparity (an oculomotor vergence error), the question arises as to whether a monocular or binocular calibration is more precise and physiologically more appropriate. In monocular calibrations, a single eye fixates on a calibration target that is taken as having been projected onto the center of the fovea; the corresponding vergence state represents the heterophoria (the resting vergence position), which has no effect on the calibration procedure. In binocular calibrations, a vergence error may be present and may affect the subsequent measurement of the fixation disparity during binocular recordings. This study includes a test of the precision of both monocular and …

Relationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.

2016

Abstract Introduction and objectives The caloric test is the gold standard for the loss of vestibular function diagnosis. The video head impulse test (vHIT) assesses the same reflex by using a video-assisted examination of the impulsive manoeuvre. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at two different moments of their evolution and to check the level of correlation between them and with that of the DHI test. Methods We explored 20 patients with neuritis by using both vHIT and the caloric test on the same day. We assessed the correlation between these two tests and with the D…

Torsional eye movement responses to monaural and binaural galvanic vestibular stimulation: side-to-side asymmetries.

2003

Vestibular stimulation by head accelerations always involves multisensory activation of the vestibular, somatosensory, and visual systems. Over the past few years, galvanic vestibular stimulation (GVS) has become increasingly popular for testing vestibular function for clinical and research purposes. Although GVS provides a nonphysiological stimulation, it is more selective than natural head accelerations and is thus an attractive tool for such tests. Eye movement responses elicited by GVS mainly consist of torsional and horizontal components, as first described by Hitzig in 1871. Animal experiments have shown that GVS increases the vestibular afferent spike frequency at the cathodal site a…

Contrast echocardiography of the left ventricle an independent predictor of pulmonary artery pressure?

1994

To test the hypothesis that left heart opacification is dependent on pulmonary artery pressure, we analyzed consecutively 12 patients with normal and 8 patients with abnormal pulmonary artery pressure with a new lung capillary stable echo contrast agent. Patients underwent contrast echocardiographic examination within 6 hours before right and left heart catheterization with 200 mg/ml and 400 mg/ml SHU 508A intravenously. The mean pulmonary artery pressure was 15.4 mmHg in the patients with normal pulmonary artery pressures and 46.4 mmHg in the patients with pulmonary hypertension (p0.000). Echocardiograms were video-intensitometrically analyzed for intensity maximum (MAX), half-time of vide…

Capsule Endoscopy versus Push Enteroscopy in Patients with Occult Gastrointestinal Bleeding

2003

Background Wireless capsule endoscopy is a new method enabling non-invasive diagnostic endoscopy of the entire small intestine. In this study we prospectively examined the diagnostic precision of capsule endoscopy compared with push enteroscopy in patients with occult gastrointestinal bleeding. Methods Between July 2001 and October 2002 we examined 48 patients with suspected disorders of the small intestine using capsule endoscopy. 33 patients with obscure bleeding (19 men, 14 women, mean age 58 +/- 23 years) were prospectively examined using capsule endoscopy and push enteroscopy. Results On average, the patients had been suffering from chronic gastrointestinal bleeding for 30 +/- 36 (1-12…

The effects of informed consent format on preoperative anxiety in patients undergoing inferior third molar surgery

2013

Objectives: To evaluate the effect of informed consent format on preoperative anxiety of patients. Material and Methods: We performed a prospective study (91 patients) undergoing lower third molar extraction. Patients were distributed into three groups. Informed consent for surgery was obtained through a written document, an oral interview or a video recording. Afterwards, patients were asked about their anxiety level and the effect the informed consent had had on it. Results: Whereas the information conveyed both in oral and written formats relieved the patient to some extent (in a scale of -3 to +3) 0.97±1.21 and 0.29±0.97, respectively), the video recording increased patient’s anxiety in…

Benign paroxysmal positioning vertigo: diagnosis and therapy using video-oculographic control.

2003

In this prospective study, 82 patients (40 males, 42 females, aged between 15 and 80 years) with benign paroxysmal positioning vertigo (BPPV) were treated with different positioning manoeuvres using video-oculographic control. The maximum age for females and males was 31 and 40 years respectively. After an interview about the special history related to vertigo imbalance symptoms and using video-oculographic control, we diagnosed 79 patients with BPPV of the posterior semicircular canal and 3 of the horizontal semicircular canal. The Dix-Hallpike and Cawthorne manoeuvres were used for the diagnosis of BPPV of the posterior semicircular canal and the McClure manoeuvre for the diagnosis of BPP…
