Ablative treatments currently represent the first-line option for the treatment of early stage unresectable hepatocellular carcinoma (HCC). Furthermore, they are effective as bridging/downstaging therapies before orthotopic liver transplantation. Contraindications based on size, number, and location of nodules are quite variable in literature and strictly dependent on local expertise. Among ablative therapies, radiofrequency ablation (RFA) has gained a pivotal role due to its efficacy, with a reported 5-year survival rate of 40%-70%, and safety...

Unnecessary confusion still surrounds the use of combined hormonal contraceptives (CHCs) in the setting of migraine with aura (MwA). Clearing this confusion is a key issue for headache specialists, since most women with migraine have menstrual-related migraine (MRM), and some CHCs can prevent this particularly severe migraine. Their use, however, is still restricted by current guidelines due to concerns of increased stroke risk - concerns that originated over half a century ago in the era of high dose contraceptives...

BACKGROUND: In symptomatic Chiari malformation type 1 (CMI), impaired intracranial compliance (ICC) is associated with an increased cranio-spinal pulsatile pressure gradient. Phase-contrast magnetic resonance imaging (MRI) represents a non-invasive modality for the assessment of the pulse pressure gradient at the cranio-cervical junction (CCJ). We wished to explore how the MRI-derived pulse pressure gradient (MRI-dP) compares with invasively measured pulsatile intracranial pressure (ICP) in CMI, and with healthy controls...

Percutaneous radiofrequency ablation (RFA) can be as effective as surgical resection in terms of overall survival and recurrence-free survival rates in patients with small hepatocellular carcinoma (HCC). Effectiveness of RFA is adversely influenced by heat-sink effect. Other ablative therapies could be considered for larger tumors or for tumors located near the vessels. In this regard, recent improvements in microwave energy delivery systems seem to open interesting perspectives to percutaneous ablation, which could become the ablation technique of choice in the near future...

Tumor ablation is defined as the direct application of chemical or thermal therapy to eradicate or substantially destroy a tumor. Currently, minimally invasive ablation techniques are available for the local destruction of focal tumors in multiple organ sites. Microwave ablation is premised on the biological response of solid tumors to tissue hyperthermia, and it is a relatively low-risk procedure. Due to several advantages of microwave ablation, including higher thermal efficiency, higher capability for coagulating blood vessels, faster ablation time, and the simultaneous application of multiple antennae, microwave ablation could be a promising minimally invasive ablation technique for the treatment of solid tumors...
