Stenosis or occlusion of central veins in hemodialysis patients is common, especially with previous intravascular catheter or device use. Superior vena cava (SVC) obstruction is emerging as a frequent chronic complication of central vein cannulation that not only jeopardizes the availability of vascular access for hemodialysis, but can become a life-threatening emergency. Clinical features of SVC syndrome can be subtle or dramatic, including facial swelling and shortness of breath, which require expeditious attention and intervention...

BACKGROUND: Radiofrequency technology is one of the most recently developed methods for noninvasive skin tightening and facial contouring, and works by generating thermal energy in the deep dermis. Although clinical improvements have been reported using radiofrequency devices, there are few histologic and molecular studies about the mechanisms of dermal collagen remodeling. The authors investigated the histologic effects of an ultra-high-frequency electrical field (40.68 MHz) radiofrequency device (Polargen) on collagen remodeling in hairless mouse skin and evaluated its relative molecular mechanism...

INTRODUCTION: The shape and contour of the chin and neck play an important role in facial esthetics. As such, excess fat within the submental area (double chin) can negatively affect facial esthetics and body image. Common treatments for submental contouring include invasive procedures such as surgical rejuvenation and targeted liposuction. Energy devices (lasers, radiofrequency, and ultrasound) may be used to improve submental skin laxity while cryolipolysis was recently cleared in the United States for use in the submental area...

BACKGROUND: Neurosurgical pain management of drug-resistant trigeminal neuralgia (TN) is highly challenging. Microvascular decompression is a first-line neurosurgical approach for classical TN with neurovascular conflict, but can show clinical relapse despite proper decompression. Second-line destructive techniques like radiofrequency thermocoagulation have become reluctantly used due to their potential for irreversible side effects. Subcutaneous peripheral nerve field stimulation (sPNFS) is a minimally invasive neuromodulatory technique which has been shown to be effective for chronic localised pain conditions...

REVIEW
Karol A Gutowski
Microfocused ultrasound (MFU) generates tissue heating, which can be used for facial skin tightening as well as other areas of skin laxity. Unlike radiofrequency energy, MFU can penetrate deep into tissue without heating the superficial skin structures, allowing for higher treatment temperatures. Depending on patient factors and treatment protocols, 60% to 90% of patients can expect to see facial improvement 6 months after treatment.

For skin tightening, ablative and nonablative lasers have been used with various parameters full or fractionated. Currently, other energy-based technologies have been developed such as radiofrequency (RF) from mono- to multipolar, microneedling RF, and high-intensity focused ultrasound. They heat up the tissue to a clinical endpoint. Temperatures above 42°C stimulate fibroblasts to produce more collagen and some technologies produce small coagulation points that allow to shrink and to tighten the tissue with less downtime or side effects...
