LUS-targeted assessment of LP was a useful predictor of pneumothorax volume in this research study setting. LUS reliably classified pneumothorax size when compared to criteria based on CXR reading, particularly the small sized pneumothorax. However, LUS greatly outperformed conventional CXR reading for a graded quantification of the percentage of lung collapse.

CB is more accurate than FNAB and should be preferred in renal mass biopsy. FNAB may precede CB when an expert pathologist can immediately evaluate the samples. Renal biopsy influences renal mass management.

INTRODUCTION: Pisa syndrome is a disabling, medication-resistant, postural abnormality that may affect 7-10% of patients with Parkinson's disease. In this study, we sought to assess the efficacy of botulinum toxin injections in Parkinson's diseaseassociated Pisa syndrome using a Magnetic Resonance Imaging-, Ultrasonography-, and Electromyography-guided combined approach. METHODS: We conducted a pilot study to evaluate the efficacy of botulinum toxin type-A injection in paraspinal and non-paraspinal axial muscles after a Magnetic Resonance Imaging and ultrasound-guided electromyography evaluation. Inclusion criteria were Pisa syndrome, idiopathic Parkinson's disease, and stable dopaminergic medications. Exclusion criteria were previous treatment with botulinum toxin, history of major spine surgery, and severe orthopedic diseases. As primary endpoint, we measured the rate of patients improving by at least 5° in the lateral trunk flexion 2 months after therapy. Secondary endpoints were the extent of lateral trunk flexion improvement, and changes in PS-associated pain/discomfort, measured by the Visual Analogue Scale. RESULTS: Out the 15 patients initially enrolled, 13 completed the follow-up assessment, while 2 joined a rehabilitation program and were excluded from the analyses. The rate of responders was 84.6% (n= 11/13), with 40% average reduction in trunk bending. Pain/discomfort improved in all patients, with 52.2% amelioration at the Visual Analogue Scale. The procedure was well tolerated in all cases, without side effects or complications. CONCLUSION: A combined imaging and EMG botulinum toxin approach to Pisa syndrome may yield a success rate greater than 80% in Parkinson's disease. Artusi 4

Chest US was found to be a valuable diagnostic tool in pneumothorax diagnosis, with diagnostic effectiveness well beyond X-rays and similar to CT.

Abstract. The identification of cystic lesions within the retroperitoneal space is a rare event that poses clinicians the challenge of a difficult diagnosis and disease management. Retroperitoneal cystic lesions account for a group of lesions that range from common benign lesions (e.g., lymphoceles developing as a surgical complication) to rare aggressive malignant neoplasms. Currently, in the majority of cases, image-guided procedures allow for a pathological diagnosis to be achieved in these challenging lesions, thus offering the chance of an appropriate treatment; however, the overall clinical assessment of retroperitoneal cysts is highly demanding. The present study reports the management of a representative clinical case, presenting with a voluminous cystic mass able to dislocate cave vein, whose diagnosis was preceded by a deep vein thrombosis. Computed tomography-scan and ultrasound guided percutaneous drainage were performed to achieve the diagnosis. Following the discussion of the current case report, a review of the pathological and radiological characteristics of retroperitoneal cystic lesions is presented.

Our preliminary results should encourage further trials of this technique. MWA proved to be feasible and safe in treating advanced-stage liver tumours and represented an additional therapeutic attempt to be validated in further and larger efficacy studies.
