Preserved visual-vestibular interaction in patients with bilateral vestibular failure
2004
Background: During caloric vestibular stimulation, subjects showed bilateral activation of the vestibular cortex in the posterior insula and retroinsular region as well as concurrent deactivation of visual cortex areas bilaterally. This finding was the basis for the concept of a reciprocal inhibitory interaction between the vestibular and the visual systems. Objective: To analyze the modulations of this activation and deactivation pattern in patients with loss of vestibular input, that is, in patients with bilateral vestibular failure (BVF). Methods: Modulations of regional cerebral blood flow (rCBF) in PET were measured in nine patients with BVF and compared with those in healthy volunteer…
Immunosuppressive treatment in bilateral vestibulopathy with inner ear antibodies.
2005
Although vestibular recovery was observed after steroid treatment, it remains uncertain whether this improvement was spontaneous or due to medication. These data do not allow us to generally recommend corticosteroid treatment in patients with BVF and inner ear antibodies.A retrospective study was performed based on the observation of two patients with suspected autoimmune bilateral vestibular failure (BVF) with normal hearing and antilabyrinthine or nervous tissue-specific serum antibodies who showed vestibular recovery after corticosteroid treatment.Twelve patients with BVF and serum inner ear antibodies who had received imuunosuppressive treatment with corticosteroids were evaluated in te…
Versatility of the Free Anterolateral Thigh Flap in the Reconstruction of Large Defects of the Weight-Bearing Foot: A Single-Center Experience with 2…
2016
Background Reconstruction of the weight-bearing surface of the foot represents a challenging task. With very little scope to borrow glabrous tissue from adjacent areas means that achieving a “like for like” reconstruction is rarely possible. In this setting, alternative approaches need to be considered. In this article we present our experience with various differing designs of the anterolateral thigh flap (ALT) in the reconstruction of 20 large defects of the weight-bearing sole. Methods Twenty patients with complex soft tissue defects of the weight-bearing sole underwent reconstruction over a 5-year period. Five cases were complicated by osteomyelitis resulting in significant calcaneal …
Evaluation of total alloplastic temporo-mandibular joint replacement with two different types of prostheses : a three-year prospective study
2015
Background Temporo-Mandibular Joint (TMJ) replacement has been used clinically for years. The objective of this study was to evaluate outcomes achieved in patients with two different categories of TMJ prostheses. Material and Methods All patients who had a TMJ replacement (TMJR) implanted during the study period from 2006 through 2012 were included in this 3-year prospective study. All procedures were performed using the Biomet Microfixation TMJ Replacement System, and all involved replacing both the skull base component (glenoid fossa) and the mandibular condyle. Results Fifty-seven patients (38 females and 19 males), involving 75 TMJs with severe disease requiring reconstruction (39 unila…
The affective response to health-related information and its relationship to health anxiety: An ambulatory approach
2014
Affective reactions to health-related information play a central role in health anxiety. Therefore, using ambulatory assessment, we analysed the time course of negative affect in a control group (CG, n = 60) which only rated their negative affect and an experimental group (EG, n = 97) which also rated the presence of somatic symptoms (e.g., back pain). By means of mixed regression models, we observed a decline of negative affect following the symptom self-ratings in the EG and a stable affect in the CG. The decline of negative affect was not moderated by the degree of health anxiety. Our findings might indicate that evaluating one's health status leads to a general reduction of negative aff…
Assessing audiological, pathophysiological and psychological variables in tinnitus patients with or without hearing loss
2010
The aim of this work is to study the characteristics of tinnitus both in normal hearing subjects and in patients with hearing loss. The study considered tinnitus sufferers, ranging from 21 to 83 years of age, who were referred to the Audiology Section of Palermo University in the years 2006–2008. The following parameters were considered: age, sex, hearing threshold, tinnitus laterality, tinnitus duration, tinnitus measurements and subjective disturbance caused by tinnitus. The sample was divided into Group1 (G1), 115 subjects with normal hearing, and Group2 (G2), 197 subjects with hearing loss. Especially for G2, there was a predominance of males compared to females (P = 0.011); the highest…
Effects of drug therapy on cardiac arrhythmias and ischemia in hypertensives with LVH.
2001
Left ventricular hypertrophy (LVH) in hypertensive subjects is associated with an increased prevalence of ventricular arrhythmias. To evaluate the effect of antihypertensive treatment on cardiac arrhythmias (CA) and transient episodes of myocardial ischemia (TEMI), we studied 46 hypertensive patients with LVH, divided into four groups randomly treated with enalapril, hydrochlorothiazide (HCTZ), atenolol, or verapamil (SR-V) for 6 months. Office blood pressure and office heart rate values were recorded, in basal conditions, after 1 and 6 months of treatment, and all patients underwent echocardiography, electrocardiographic Holter monitoring, and stress testing. All drugs significantly lowere…
Sympathetic Activity and Blood Pressure Pattern in Autosomal Dominant Polycystic Kidney Disease Hypertensives
1998
To study the potential role of sympathetic activity in the pathogenesis of arterial hypertension associated with autosomal dominant polycystic kidney disease (ADPKD) and to analyze its relationship with 24-hour blood pressure pattern, plasma catecholamines and 24-hour ambulatory blood pressure monitoring were evaluated in 30 ADPKD hypertensive patients (of which 17 without and 13 with renal failure) and in 50 essential hypertensives. The groups were matched for sex, body mass index, known duration of hypertension, and clinic blood pressure. Plasma catecholamines, determined in resting position, were higher in ADPKD patients without renal failure than in essential hypertensives. Nighttime di…
Enhancing the efficacy of treatment for temporomandibular patients with muscular diagnosis through cognitive-behavioral intervention, including hypno…
2011
Objective This study evaluated the efficacy of a cognitive-behavioral therapy (CBT), including hypnosis, in patients with temporomandibular disorders (TMDs) with muscular diagnosis. Study Design Seventy-two patients (65 women and 7 men with an average age of 39 years) were selected according to the Research Diagnostic Criteria for TMD, and assigned to the experimental group (n = 41), receiving the 6-session CBT program, and the control group (n = 31). All patients received conservative standard treatment for TMD. The assessment included pain variables and psychologic distress. Results There were significant differences between the groups, the experimental group showing a higher improvement …
Twenty-Four Hour Ambulatory Blood Pressure Monitoring to Evaluate Effects on Blood Pressure of Physical Activity in Hypertensive Patients
2006
OBJECTIVE: Elevated blood pressure is an important risk factor for cardiovascular disease and stroke. Several studies have demonstrated that physical exercise reduces blood pressure levels in hypertensive subjects and improves control of several well-known risk factors for atherosclerosis such as diabetes mellitus, blood lipid profile and obesity. Our group attempted to evaluate if an exercise program based on periodic controlled fast walking sessions would reduce blood pressure levels in hypertensive subjects. DESIGN: We enrolled hypertensive subjects not suffering from obesity (Body Mass Index <30) already under pharmacological therapy; in these subjects we performed a six-week program of…
