Immediate structural changes of porcine renal arteries after angioplasty: a histological and morphometric study.

The aim of this research was to characterize the immediate alterations induced by angioplasty and to compare the results of the application of two types of balloons. Ten porcine renal arteries were dilated with a compliant balloon, and ten with a non-compliant balloon. After angioplastic treatment arterial specimens were wax embedded for light microscopy.

A comparison between radiographic and sonographic assessment of hand and wrist bones for the estimation of skeletal age in the child patient.

Aim: The purpose of this study was to examine, with a sonographic investigation, the hand and wrist bones of a group of young patients and to compare the results with those obtained with a classical radiographic assessment.

Materials And Methods: Some 25 subjects, 9-18 years of age, who presented problems concerning their short stature or precocious puberty, were evaluated. Each subject was examined by a standard radiographic assessment and by a sonographic investigation with real-time imaging.

A comparison of ultrasonography and magnetic resonance imaging in the evaluation of temporomandibular joint involvement in rheumatoid arthritis and psoriatic arthritis.

Objective: To define the diagnostic value of ultrasonographic (US) examination in comparison with magnetic resonance imaging (MRI) for the assessment of temporomandibular joint (TMJ) involvement in rheumatoid arthritis (RA) and psoriatic arthritis (PsA).

Methods: MRI and US examinations were performed in 33 patients (22 with RA and 11 with PsA). Alterations of the disc, alterations of the condyle and joint effusion were evaluated.

[Diagnostic approach to acute laryngeal trauma: role of computerized tomography].

Aim of this study was to assess the role of Computed Tomography (CT) in the management of acute laryngeal injuries by reviewing our 5 years' experience. From January, 1991, to November, 1996, sixteen patients with blunt trauma and 2 patients with penetrating injuries of the larynx underwent physical examination, laryngoscopy and CT; 2 of them underwent angiography too. The patients were divided into 3 groups according to Schaefer classification [13], first on the basis of physical examination, CT and laryngoscopy findings.
