Controlled Clinical Trial
Post-treatment complications of soft tissue tumours.
To identify local and distant complications of patients with soft tissue tumours and evaluate their relationships to types of therapy. ⋯ This study suggests a possible relationship between types of treatment of soft tissue tumours and subsequent complications. Postoperative radiotherapy was associated with a significant number of patients with seromas, muscle, cutaneous and subcutaneous inflammation, and fractures. Incomplete or difficult surgery resulted in residual or recurrent tumours and heterotopic ossification. Muscle atrophy and nerve entrapment were related to both treatments (resection alone or radiotherapy after resection). Diligent follow-up of patients with soft tissue tumours with recognition of these complications and their differentiation from recurrent or residual tumour can help guide clinical care and may negate the need for surgery when benign disease is defined.

Comparative Study
Whole-body MRI of multiple myeloma: comparison of different MRI sequences in assessment of different growth patterns.
To determine sensitivity, specificity and inter-observer variability of different whole-body MRI (WB-MRI) sequences in patients with multiple myeloma (MM). ⋯ T2w-TIRM sequences achieved the highest level of sensitivity and best reliability, and thus might be valuable for initial assessment of MM. For an exact staging and grading the examination protocol should encompass unenhanced and enhanced T1w-MRI sequences, in addition to T2w-TIRM.

The purpose of this study was to evaluate the usefulness of diffusion-weighted (DW) MR imaging with split acquisition of fast spin-echo signals (SPLICE) in the tissue characterization of head and neck mass lesions. ⋯ SPLICE was considered a recommended DW MR imaging technique for the head and neck. Although ADC values were useful in differentiating cysts from tumors, they contributed little in predicting malignancy.

To investigate the clinical presentation of dislodged totally implantable central venous access system (central venous port-catheter) fragments and the efficacy and safety of percutaneous retrieval of them in our hospital. ⋯ The faulty connection between catheter and injection port contributes mainly to dislodgement of central venous port-catheter. Percutaneous retrieval of dislodged catheter is a highly successful, safe and efficient method.
