The detection of peripheral lung nodules is increasing due to expanded use of computed tomography (CT) and implementation of lung cancer screening recommendations. Although surgical resection of malignant nodules remains the treatment modality of choice at present, many patients are not surgical candidates, thus prompting the need for other therapeutic options. Stereotactic body radiotherapy (SBRT) and percutaneous thermal ablation are emerging as viable alternatives to surgical resection. For safety, efficacy, and cost-effectiveness purposes, however, alternative bronchoscopic methods for treatment of peripheral lung cancer are currently under active exploration...

Hepatocellular carcinoma is the major complication of chronic liver diseases and particularly of cirrhosis whatever its etiology. Once encountered mainly in the endemic countries of hepatitis B and C, the incidence of hepatocellular carcinoma (6/100,000) is parallel to the global development of diabetes, overweight and alcohol consumption. Little progress has been made for this cancer, whose mortality is 100 % at 10 years. Liver transplantation is the only truly curative treatment (survival more than 50 % at 10 years) since it allows the eradication of hepatocellular carcinoma and its essential cause, cirrhotic liver...

Percutaneous musculoskeletal procedures are widely accepted as low invasive, highly effective, efficient and safe methods in a vast amount of hip pathologies either in diagnostic or in therapeutic management. Hip intra-articular injections are used for the symptomatic treatment of osteoarthritis. Peritendinous or intrabursal corticosteroid injections can be used for the symptomatic treatment of greater trochanteric pain syndrome and anterior iliopsoas impingement. In past decades, the role of interventional radiology has rapidly increased in metastatic disease, thanks to the development of many ablative techniques...

The diffusion of imaging has determined an increased discovery of small renal masses (SRMs). Recent publications have been reviewed to present the state of the art in the management of SRMs and to try to foresee the next steps in this challenging condition. The role of percutaneous biopsies is expanding, since management algorithms include also active surveillance and ablative therapies. However up to 30% of biopsies fail to provide histological diagnosis and there is the risk of under-evaluating high-grade tumors...

Cryoplasty may reduce the incidence of post-angioplasty restenosis in peripheral atherosclerotic arteries. Our study is looking to investigate the mid-term effects (4 weeks) of an FDA-approved cryoplasty catheter (PolarCath(®), Boston Scientific) compared to a conventional angioplasty catheter using a hypercholesterolemic rabbit model of arterial restenosis based on diet plus vessel injury. Thirty-six normolipidemic, 3-month old male New Zealand White rabbits were used. Balloon angioplasty was performed on left external iliac arteries on day 1...

Skeletal metastasis is a common cause of severe morbidity, reduction in quality of life (QOL) and often early mortality. Its prevalence is rising due to a higher rate of diagnosis, better systemic treatment, longer lives with the disease and higher disease burden rate. As people with cancer live longer and with rising sensitivity of body imaging and surveillance, the incidence of pathological fracture, metastatic epidural cord compression is rising and constitutes a challenge for the orthopedic surgeon to maintain their QOL...

Cryotechnology has been used in treating lung cancer for many years, now it is emerging to have a new indication in diagnosing lung diseases. Cryoprobe transbronchial lung biopsy has been introduced into clinical practice as a new technique, providing a larger biopsy specimen, potentially improving the diagnostic yield of transbronchial biopsies in parenchymal lung diseases. Although recent small pilot studies suggest that cryotransbronchial lung biopsies are comparable to conventional transbronchial biopsies in terms of diagnostic yield and safety profile in lung transplant patients, cryoprobe transbronchial lung biopsy is still being evaluated and its role in clinical practice is not well defined...

Proper neuromuscular activation of the quadriceps muscle is essential for maintaining quadriceps (quad) strength and lower-extremity function. Quad activation (QA) failure is a common characteristic observed in patients with knee pathologies, defined as an inability to voluntarily activate the entire alpha-motor-neuron pool innervating the quad. One of the more popular techniques used to assess QA is the superimposed burst (SIB) technique, a force-based technique that uses a supramaximal, percutaneous electrical stimulation to activate all of the motor units in the quad during a maximal, voluntary isometric contraction...
