We developed the head impulse testing device (HITD) based on an inertial sensing system allowing to investigate the functional performance of the rotational vestibulo-ocular reflex (VOR) by testing its gaze stabilization ability, independently from the subject's visual acuity, in response to head impulses at different head angular accelerations ranging from(More)
The paranasal sinus epithelium is exposed to the environment and therefore to a variety of biological, chemical and mechanical insults. Surfactant protein A (SP-A) is a 34–36 kD pulmonary surfactant-associated protein that appears to play an important role in mammalian first-line host defence. Recent studies have reported the possibility of local production(More)
We evaluated the incidence and characteristics of hyperventilation-induced nystagmus (HVN) in 49 patients with gadolinium-enhanced magnetic resonance imaging evidence of vestibular schwannoma and 53 patients with idiopathic unilateral sensorineural hearing loss and normal radiological findings. The sensitivity and specificity of the hyperventilation test(More)
The paper evaluates the role of ultrasound examinations of the hip joint in neonates by comparing the results of a one-year screening study (non-selected group) with the findings in a selected group of neonates with a high risk of hip dysplasia. The introduction to the paper contains a general discussion of the clinical aspects of hip dysplasia and(More)
From August 1983 to December 1985, 2352 radiological examinations of the colon were performed in the Radiology Department of Università Cattolica del Sacro Cuore of Rome. From this group a sample of 222 patients was analyzed. They included 111 patients with colonic polyps and 111 with cancer. These cases were carefully examined, in terms of age, frequency(More)
We studied 12 children with echocardiographic evidence of mitral valve prolapse (MVP) in order to demonstrate platelet activation or consumption as risk for thromboembolism. Therefore, with a standard radioimmunoassay, we measured the plasma levels of Beta-thromboglobulin (BTG), a platelet-specific protein released during platelet release reaction. Platelet(More)
The aim of this study was to assess the natural course of positional down-beating nystagmus (pDBN) and vertigo in patients with no evidence of central nervous system involvement and of presumed peripheral origin. Fifty-three patients with pDBN had a complete otoneurological examination. All subjects, apart from three (excluded from the study), showed no(More)
