We carried out a single-blind study with 13-MHz high resolution probes and electromyography on 132 patients with clinical evidence of the carpal tunnel syndrome; a control group of 20 asymptomatic patients was also submitted to US. Eighty-six of 107 patients with US signs of the carpal tunnel syndrome were then submitted to surgical decompression (resection of the transverse carpal ligament), while the extant 21 patients underwent conservative treatment and clinical follow-up. To diagnose the carpal tunnel syndrome, we considered the following US patterns: median nerve changes (swelling before its entrance into the carpal tunnel and flattening in the tunnel itself), palmar bowing of the flexor retinaculum, thickening of the transverse carpal ligament and increased depth of the carpal tunnel, as measured from the apex of the transverse carpal ligament convexity to the underlying carpal bo...

Even if widespread antibiotic therapy and modern imaging technologies combined with minimally invasive techniques have improved the outcome in patients with brain abscesses, this is counterbalanced by an increasing population of immunocompromised patients. Basal ganglia, thalamic, brainstem or multiple abscesses are usually of hematogenous origin with an underlying source of infection which can include congenital heart disease, thoracic sepsis or, less frequently, an odontogenic or otogenic source. However, no evident foci of sepsis or predisposing factors may be found. Only a few studies are reported in the literature, because midline abscesses are usually included in studies dealing on the treatment of abscesses in general. Different treatment options and the timing of treatment are described. We report our experience in 3 consecutive cases of thalamic abscess, treated by stereotactic puncture as the f...

The patient was treated surgically with resection of both the cerebral and intestinal lesions followed by cerebral radiotherapy. A pulmonary metastasis was discovered after 3 months and treated with interferon and octreotide. No further cerebral or intestinal relapses were observed. The patient died of cardiac disease 11 months after the first operation. Central nervous system metastases from carcinoid tumours are rare. The reported survival in untreated cases or in cases treated by radiotherapy alone is 4 months. In the case reported, surgical resection of the cerebral and intestinal lesions followed by intracranial radiotherapy yielded complete local control of the disease and a slight improvement in survival.

Twenty patients each in the expandable and cement-augmented screw groups were recruited. Clinical outcomes included visual analog scale (VAS), Oswestry Disability Index (ODI), and satisfaction rates. Radiographic outcomes comprised radiological measurements on the vertebral motion segment of the treated levels. Intraoperative data including complications were collected. All patients completed the clinical and radiological outcomes. Outcomes were compared preoperatively and postoperatively.RESULTSAn average shorter operative time was found in procedures in which expandable screws were used versus those in which...
