The value of ultrasound-guidance of nerves and muscles for patient tolerance and parameters electrodiagnostic studies.

Objective: To assess impact of ultrasound guidance (USG) on patient's perception of nerve conduction studies (NCS).

Methods: In this single-center, randomized, sham-controlled, parallel, single-blind trial, we evaluated ultrasound (US) in identifying NCS stimulation site. Consecutive adults (18-80 old) without neuropathy referred for NCS were electronically randomized 1:1 to USG or Sham US.

Contribution of Single-Fiber Evaluation on Monitoring Outcomes Following Injection of Botulinum Toxin-A: A Narrative Review of the Literature.

Botulinum toxin-A (BoNT-A) blocks acetylcholine release at the neuromuscular junction (NMJ) and is widely used for neuromuscular disorders (involuntary spasms, dystonic disorders and spasticity). However, its therapeutic effects are usually measured by clinical scales of questionable validity. Single-fiber electromyography (SFEMG) is a sensitive, validated diagnostic technique for NMJ impairment such as myasthenia.

[Diagnostic value of a breast MRI score for the prediction of malignancy of breast lesions detected solely with MRI].

Purpose: To determine whether lesion scoring allows valid BI-RADS ((R)) classification and prediction of malignancy of breast lesions detectable solely with MRI.

Materials And Methods: Retrospective analysis of 86 patients who underwent MRI-guided localization and excisional biopsy of 100 breast lesions detectable only with MRI. Breast MRI was performed at 1.

[Plasma-cell osteomyelitis of the thoracic spine--a case report].

The authors report the case of a young patient suffering from plasmacellular osteomyelitis of the thoracic spine, a unusual localisation of this type of chronic osteomyelitis. They discuss the role of imaging diagnostic modalities in this disease, focussing on MRI.

[Jejunal leiomyosarcoma. A case report].

Jejunal leiomyosarcoma, is an uncommon neoplasm. Diagnosis can be difficult because symptoms may be vague and nonspecific. We report the case of a 33-years-old patient, which was diagnosed and operated of this infrequent pathology.
