Directional Control Mechanisms in Multidirectional Step Initiating Tasks.
2020
Typical anticipatory postural adjustments (APAs) in forward gait or step initiation tasks to prepare for possible disturbances caused by prime voluntary movements and to accelerate the body forward have been previously reported. However, it is not clear how wide the variations in step directions are differentiated and controlled in non-forward step initiation tasks during the APA phase. The main goal of this study is to explain the directional control mechanisms by investigating the APA of step initiation tasks in forward, diagonal, lateral, and posterior directions. The center of pressure (COP) trajectories and related muscle (soleus, tibialis anterior, and gluteus medius of both lower lim…
Recognition and characterization of small colonic neoplasia with high-definition colonoscopy using i-Scan is as precise as chromoendoscopy
2010
Abstract Background The EPKi system (Pentax, Japan) enables resolution above HDTV. Aim of the study was to test the efficacy of HD+ alone and with the new post-processing digital filter i-Scan or chromoendoscopy (Methylene blue 0.1%) in screening for colorectal cancer. We focused on lesions less than 5 mm as a surrogate marker for the optical possibilities of the EPKi system. Methods The last 30 cm of the colon in a screening population were inspected with HD+ alone, in combination with i-Scan (2:1 randomisation) and subsequently with chromoendoscopy. All lesions were characterized and targeted biopsies were performed. Results i-Scan augmented in 69 patients the identification of lesions fr…
Epidemiology of retinitis pigmentosa in the valencian community (Spain)
1995
The purposes of this study are to determine the frequencies of the different genetic forms of retinitis pigmentosa and to perform segregation analysis in the different genetic subtypes. Retinitis pigmentosa was diagnosed in 263 persons from 132 families. The frequency of the autosomal recessive type was the highest (31.8%) while the X-linked type was very rare (1.5%). The frequency of autosomal dominant type was 14.4% and the simplex cases constituted half of the total cases of RP registered in our community. In conclusion, in our population the high proportion of simplex cases and the low number of X-linked families are noticeable. The result of segregation analysis showed good agreement w…
Treatment of Congestive Heart Failure in the Elderly
1998
Congestive heart failure (CHF) is a complex clinical syndrome which constitutes the epilogue of the natural history of virtually all heart diseases and in its advanced stages, has a poor prognosis. In the elderly, heart failure exhibits particular characteristics linked to the age-related alterations of cardiovascular system, to the association with other pathologies, to the atypical clinical presentation and to the increased iatrogenic risk. Heart failure now afflicts over 1% of the general population with nearly 1 in 10 elderly subjects affected, and the frequency of CHF is progressively increasing in most industrialized societies1,2. Further, CHF remains a significant cause of death and …
Modelling cardiac mechanics of left ventricular noncompaction
2020
Left ventricular noncompaction (LVNC) can be defined as a cardiomyopathy characterised by a pattern of prominent trabecular structure and deep intertrabecular recesses, that is thought to be caused by an arrest of normal endomyocardial morphogenesis. Using patient-specific computational modelling, we assessed the cardiac mechanics of five patients with LVNC and compared myocardial stress and pump performance to those of healthy controls. Findings shown that patients with LVNC have impaired left ventricular (LV) function, making it possible that the lack of fibre shortening of noncompacted layer can determine poor heart function. Pronounced end-systolic wall stress on left ventricular wall o…
Spotlight on fundus autofluorescence.
2018
Fundus autofluorescence (FAF) imaging is based on the fluorescence from ocular endogenous fluorophores located in the retinal pigment epithelium and choroid, mainly lipofuscin and melanin. It is a noninvasive technique that provides information about the spatial distribution of lipofuscin/melanin and retinal pigment epithelium health status. An overview about the fluorophores responsible for FAF imaging and the usefulness of FAF imaging in the noninvasive assessment and monitoring of retinal diseases, such as age-related macular degeneration, diabetic retinopathy, diabetic macular edema, central serous chorioretinopthy, retinitis pigmentosa and retinal dystrophies, are discussed in this rev…
Factors associated with the subjective health complaints among adolescents: Results from the ASSO Project
2019
Objectives. Subjective health complaints (e.g. headache and feeling low) are common among adolescents. The objective of this study was to identify the factors associated with the subjective health of adolescents from a population-based point of view. Material and methods. A sample of 712 students was recruited within the web-based Project ASSO (Adolescents and Surveillance System for the Obesity prevention), funded by the Italian Ministry of Health and piloted in Palermo. A 0-100 quantitative score (arbitrarily named "psychosomatic malaise index") based on the frequency of occurrence of seven subjective health complaints was created and used as outcome; socio-demographic characteristics, me…

Diagnosis of Tinnitus: Neurological Examination
2011
1. There is an urgent need for a set of assessment methods to be agreed upon and utilized by the international tinnitus research community. 2. Neurological examination of tinnitus patients is essential to achieve a good diagnostic approach to the different forms of objective and subjective tinnitus. 3. This chapter summarizes the neurological examination in tinnitus, including the protocol used in the authors’ tinnitus clinic, which is based on the consensus of the Tinnitus Research Initiative (TRI).
