Short-term Follow-up after Implantation of a Foldable Iris-Fixated Intraocular Lens in Phakic Eyes
2005
Objective To evaluate efficiency, predictability, stability, complications, and patient satisfaction after implantation of a foldable iris-fixated phakic intraocular lens (PIOL) for the correction of myopia. Design Prospective, nonrandomized, comparative (self-controlled) trial. Participants Forty-one eyes of 22 myopic patients aged 18 to 56 years (mean, 36 years) with average sphere of −8.2±2.01 diopters (D; range, −12.25 to −3.75 D) and average preoperative cylinder of −0.90±0.62 D (range, −2.50 to 0.00 D) were enrolled in this prospective study. Methods All eyes underwent implantation of a foldable iris-fixated PIOL with an optical zone of 6.0 mm. The follow-up was 6 months in all cases.…
Comparison of peri-implant bone loss between conventional drilling with irrigation versus low-speed drilling without irrigation
2016
Background To compare the technique of high speed drilling with irrigation and low speed drilling without irrigation in order to evaluate the success rate and peri-implant bone loss at 12 months of follow-up. Material and Methods A randomized, controlled, parallel-group clinical trial was carried out in patients requiring dental implants to rehabilitate their unitary edentulism. Patients were recruited from the Oral Surgery Unit of the University of Valencia (Spain) between September 2014 and August 2015. Patients who met the inclusion criteria were randomized to two groups: group A (high-speed drilling with irrigation) and group B (low-speed drilling without irrigation). The success rate a…
A new approach based on Machine Learning for predicting corneal curvature (K1) and astigmatism in patients with keratoconus after intracorneal ring i…
2014
Keratoconus (KC) is the most common type of corneal ectasia. A corneal transplantation was the treatment of choice until the last decade. However, intra-corneal ring implantation has become more and more common, and it is commonly used to treat KC thus avoiding a corneal transplantation. This work proposes a new approach based on Machine Learning to predict the vision gain of KC patients after ring implantation. That vision gain is assessed by means of the corneal curvature and the astigmatism. Different models were proposed; the best results were achieved by an artificial neural network based on the Multilayer Perceptron. The error provided by the best model was 0.97D of corneal curvature …

Laparoscopic adrenalectomy: preoperative data, surgical technique and clinical outcomes
2019
Background: laparoscopic adrenalectomy has become the standard treatment for adrenal lesions. The better clinical outcoms of laparoscopic technique are valid for treatment of small benign masses (< 5-6 cm), instead there are still open questions in literature regarding the correct management of larger lesions (> 6 cm) or in case of potentially malignant adrenal tumors. The aim of this study is to evaluate the outcomes of laparoscopic adrenalectomy in a referral surgical department for endocrine surgery. Methods: at the University Hospital Policlinico "P. Giaccone" of Palermo between January 2010 and December 2017 we performed a total of 81 laparoscopic adrenalectomy. We created a retr…
Three-dimensional (3D) versus two-dimensional (2D) laparoscopic adrenalectomy: A case-control study
2016
Abstract Introduction Laparoscopic adrenalectomy is today considered the gold standard of treatment for adrenal tumors. The development of high definition cameras does not eliminate the major limitation of two-dimensional (2D) laparoscopy: lack of depth perception and loss of spatial orientation. Tree-dimensional (3D) HD laparoscopy was developed as an alternative to conventional 2D laparoscopy. Methods We report our experience with use of 3D vision system for laparoscopic adrenalectomy. Between January 2009 and March 2015 we performed a total of 52 laparoscopic adrenalectomies. In this case-control study we considered 13 laparoscopic adrenalectomies performed with three-dimensional (3D) vi…
Rupture of supra-aortic neck arteries due to lesions caused by tracheal tubes
1984
Haemorrhages from the common carotid or innominate artery caused by tracheal tubes are rare but dramatic complications of head and neck surgery. Patients with metal tracheostomy cannulas or patients in the phase of wound healing after radical tumour resections of the pharynx and larynx run a greater risk. Following extensive tumour resections and radiation of the upper respiratory and digestive tracts in 680 patients, acute bleeding of the larger neck arteries occurred in 18 patients. In four of these cases, fistulae developed in the innominate or common carotid artery. These ruptures were caused by both plastic and metal tracheal tubes.
Long-Term Functional Outcome after Unilateral Cordectomy
2010
<i>Purpose of the Study:</i> Our aim was to longitudinally analyze the vocal outcome after endoscopic CO<sub>2</sub> laser resection of early glottic carcinoma. <i>Procedures:</i> Sixteen patients treated with laser surgery for T1 or T2 tumors of the vocal cords received voice therapy and were examined 1, 2, 3, 4.5, 6 and 12 months postoperatively. Besides videolaryngostroboscopy, each examination included history, phonetogram of the speaking and the singing voice, language-specific hoarseness diagram and a questionnaire (Voice Handicap Index 12 in German). <i>Results:</i> Objective parameters demonstrated a broad variability with a slight ten…
Dipole source analyses of laser evoked potentials obtained from subdural grid recordings from primary somatic sensory cortex
2011
The cortical potentials evoked by cutaneous application of a laser stimulus (laser evoked potentials, LEP) often include potentials in the primary somatic sensory cortex (S1), which may be located within the subdivisions of S1 including Brodmann areas 3A, 3B, 1, and 2. The precise location of the LEP generator may clarify the pattern of activation of human S1 by painful stimuli. We now test the hypothesis that the generators of the LEP are located in human Brodmann area 1 or 3A within S1. Local field potential (LFP) source analysis of the LEP was obtained from subdural grids over sensorimotor cortex in two patients undergoing epilepsy surgery. The relationship of LEP dipoles was compared wi…
Transformational Leadership in the Local Police in Spain: a Leader-Follower Distance Approach
2014
AbstractBased on the transformational leadership theory (Bass, 1985), the aim of the present study was to analyze the differences in leadership styles according to the various leading ranks and the organizational follower-leader distance reported by a representative sample of 975 local police members (828 male and 147 female) from Valencian Community (Spain). Results showed differences by rank (p< .01), and by rank distance (p< .05). The general intendents showed the most optimal profile of leadership in all the variables examined (transformational-leadership behaviors, transactional-leadership behaviors,laissez-fairebehaviors, satisfaction with the leader, extra effort by follower, a…
