Prevention of Recurrent Benign Paroxysmal Positional Vertigo: The Role of Combined Supplementation with Vitamin D and Antioxidants.

Benign paroxysmal positional vertigo (BPPV) usually has a favorable course, although it is possible to observe BPPV with a high recurrence rate. Previous studies suggested that vitamin D deficiency might affect BPPV recurrences, and oxidative stress might play a complementary role in BPPV pathogenesis. This multicentric trial aimed to evaluate the effectiveness of oral nutritional supplementation with a compound of alpha-lipoic acid, Carnosine, and Zinc (LICA® (Difass International, Coriano (RN), Italy)), vitamins of group B and vitamin D in preventing BPPV recurrences.

The Navigation Ability Test (NAT 2.0): From Football Player Performance to Balance Rehabilitation in Chronic Unilateral Vestibular Loss.

Aim Of The Study: in humans, spatial orientation consists of the ability to move around the environment through memorized and pre-programmed movements, according to the afferent sensory information of the body and environmental analysis of the Central Nervous System (CNS). The purpose of this study is to analyze the abilities of professional athletes, such as footballers, to use mental navigation systems, cognitive maps, and memorized motor patterns in order to obtain better physical performance and to obtain useful information for training both non-sports subjects and vestibular patients for rehabilitation purposes.

Materials And Methods: all the motor performances of sportsmen, healthy non-sporting subjects, or vestibular patients are based on the acquisition of visual-spatial and training information.

Harmonic Scalpel vs "cold knife" dissection in uvulopalatopharyngoplasty.

Purpose: The aim of this study has been to compare the Harmonic Scalpel (HS) and the "cold knife" dissection in the treatment of snoring by uvulopalatopharyngoplasty (UPPP).

Materials And Methods: The investigation included 40 adult males with snoring. Patients were assigned to two homogeneous groups (A and B) and UPPP was performed using HS or "cold knife" dissection in groups A and B, respectively.

Effects of uvulopalatopharyngoplasty with Harmonic Scalpel on speech and voice.

The aim of this study was to evaluate changes in acoustic features of speech and voice after uvulopalatopharyngoplasty (UPPP) with the Harmonic Scalpel (HS), using the multidimensional voice program (MDVP) in conjunction with other tests. Before and 6 months after surgery, phonetically balanced sentences and sustained vowels a, e, i were carried out and digitalized with MDVP in all the patients, as an evaluation of nasal resonance (trough the Glatzel and the Gutzmann tests), speech articulation and voice handicap index (VHI). These parameters were estimated: average of fundamental frequency, Jitter, Shimmer, noise-to-harmonics ratio, voice turbulence index, soft phonation index, degree of voiceless, degree of voice breaks and peak amplitude variation.

Harmonic scalpel in pharyngolaryngectomy with radical neck dissection.

Objective: The aim of this study was to verify the efficacy and applicability of the Ultracision Harmonic Scalpel (Ethicon Endo-Surgery, Cincinnati, OH) in pharyngolaryngectomy with radical neck dissection.

Design: This work evaluated the use of the Harmonic Scalpel in otolaryngology as a new and alternative method to overcome some complications of traditional surgery.

Setting: The study was conducted with 20 patients in the ENT Department of the University of Genoa (Italy) between January 1, 2005, and December 31, 2006.

New trends in head and neck surgery: a prospective evaluation of the Harmonic Scalpel.

Background: The use of ultrasonic technology to cut and coagulate tissues with minimal tissue damage has been investigated in general surgery and gynecology. The purpose of this study was to verify the efficacy and applicability of the Harmonic Scalpel in head and neck surgery.

Material/methods: A non-randomized study was undertaken on 40 pharyngolaryngectomies, 40 total laryngectomies, 40 radical neck dissections, and 40 superficial parotidectomies performed using the Harmonic Scalpel (80 patients) or "cold knife" dissection (80 patients).
