Changes in the carpal tunnel while wearing the Manu® soft hand brace: a sonographic study.

We studied the effect of the Manu(®) soft hand brace, which has been designed to relieve median nerve entrapment in carpal tunnel syndrome. An observational, controlled study was conducted in 10 participants, five with bilateral carpal tunnel syndrome and five controls, using sonography to study changes in the dimensions of the carpal tunnel before and while wearing the brace. An increase in transverse diameter, thinning of the flexor retinaculum, and displacement of the proximal insertion of the lumbrical muscle to the middle finger from the edge of the carpal tunnel were observed in patients while wearing the brace.

[Intra-arterial infusion of PGE1 alpha cyclodextrin].

Background: Intra-arterial infusion of PGE1 alpha-ciclodestrina was achieved by intrafemoral catheter in critical limb ischemia.

Methods: The acute infusion of 10 micrograms in 20 minutes, in 50 ml of saline was followed by chronic infusion 20 micrograms/die of PGE1 alpha-ciclodestrina for 5 days. Three male patients (age 65 +/- 12) with severe critical ischemia and rest pain with initial, localised (> 0.

[Intra-osseus hidden fractures of the knee in athletes: assessment with magnetic resonance imaging].

The diagnostic capabilities of Magnetic Resonance Imaging (MRI) were investigated in the study of occult intraosseous fractures of the knees in athletes; this pathologic condition is difficult to assess with conventional diagnostic techniques. Twelve athletes were considered and submitted to MR examinations 1-8 days after trauma. All patients had undergone plain films, 6 of them CT and 3 scintigraphy.

Talocalcaneal coalition: computed tomography and magnetic resonance imaging diagnosis.

A correct evaluation of site and extension of the talocalcaneal coalition inducing biomechanical ankle alterations is very important for planning therapy. Four male patients were submitted to computed tomography (CT) and three of them were also examined by means of magnetic resonance imaging (MRI). In one patient, studied by CT only, a bilateral talocalcaneal coalition was present, while the other three patients, controlled with CT and MRI, were affected by monolateral talocalcaneal coalition which was of osseous type in one case and fibrocartilaginous in two cases.

[Magnetic resonance in the staging of multiple myeloma].

The authors retrospectively reviewed the MR examinations of 46 patients with clinical and laboratory findings of monoclonal gammopathies (MG). All cases had been submitted to radiographic examination which had shown skeletal involvement in 22 cases and osteoporosis in 11, with rupture of the vertebral body in 3 patients. Scintigraphy had been performed on all patients and CT on 12; 36 patients were subsequently submitted to follow-up (at 6, 12 and 24 months).

[Pathologic conditions in pregnancy. Preliminary evaluation of the effectiveness of magnetic resonance].

Some authors suggested that MR imaging could represent an effective diagnostic alternative in the study of pathologic conditions of mother and fetus during pregnancy. To verify the actual role of MR imaging, we examined 20 patients in the 2nd and 3rd trimester of gestation, after a preliminary US examination. Fifteen patients presented fetal or placental pathologies; in 4 patients the onset of the pathologic condition occurred during pregnancy; in 1 case of US diagnosis of fetal ascites, MR findings were normal and the newborn was healthy.
