Carpal tunnel syndrome (CTS) is an entrapment neuropathy resulting from compression of the median nerve at the carpal tunnel (CT). We assessed the role of high-resolution ultrasound (US) in monitoring patients with CTS treated with corticosteroid injection. ⋯ High-resolution US parameters such as the APD and CSA of the median nerve at the CT inlet were not useful to monitor patients with CTS treated with corticosteroid injections.

Intravascular ultrasonography (IVUS) and coronary atherectomy (CA) are useful modalities in managing calcified coronary lesions. Considering an inadequacy of data, we aimed to compare the outcomes with versus without IVUS assistance in percutaneous coronary interventions (PCIs) with CA. ⋯ IVUS-assisted procedures showed lower in-hospital mortality and higher iatrogenic and overall cardiac complications. The mortality rate in patients undergoing IVUS-assisted PCI with CA was on the rise, with declining cardiac complication rates from 2012 to 2014.

As a noninvasive method for evaluation of cerebral hemodynamics, the correct interpretation of transcranial Doppler or transcranial imaging (TCI) data remains a major challenge. We explored how to interpret the pulsatility index (PI) derived via TCI during evaluations of cerebral hemodynamics in posthemicraniectomy patients. ⋯ In posthemicraniectomy patients, the Doppler-based MCA PI value was ineffectively for quantitative ICP and CPP evaluations but a useful index for assessment of cerebral hemodynamics in terms of the probability of an ICP elevation or a CPP reduction.
