Radiation Therapy/Radio Therapy
High-definition Multileaf Collimator Radiosurgery System: In January 2008, the Palo Alto Medical Foundation in Palo Alto, CA became the first health care organization in the world with a new high-definition multileaf collimator (HD 120 MLC), an ultra-fine device for radiosurgery that shapes each treatment beam to match the exact contour of a tumor or other target. This technology allows doctors to treat brain tumors and cancer in all parts of the body with unsurpassed accuracy – all with fewer side effects, greater patient comfort and improved outcomes.
Radiosurgery is a non-invasive medical procedure in which high-energy X-rays are delivered to a target area within the body from a machine outside the body. With the HD120 MLC, which is part of PAMF’s Novalis Tx® radiosurgery system from Varian Medical Systems and BrainLab, patients receive an ultra-precise dose of high-intensity radiation – accurate within fractions of a centimeter – while avoiding the pain and complications associated with conventional “open” surgery. Palo Alto Medical Foundation March 2008 e-HealthNews Volume 5 Issue 3. Also see Radiosurgery and Cancers Treated with Radiosurgery.
A more general term for radiosurgery is Radio Frequency Ablation (RFA). Results show it to be extremely effective and can be used with advanced lung cancer where conventional surgery is not possible. Radio frequency ablation is a medical procedure where part of the electrical conduction system of the heart, tumor or other dysfunctional tissue is ablated using the heat generated from the high frequency alternating current. It essentially heats tumors and kills them. ( Radiofrequency ablation).
Radiofrequency ablation for treatment of symptomatic uterine fibroids. The use of thermal energy-based systems to treat uterine fibroids has resulted in a plethora of devices that are less invasive and potentially as effective in reducing symptoms as traditional options such as myomectomy. Most thermal ablation devices involve hyperthermia (heating of tissue), which entails the conversion of an external electromagnetic or ultrasound waves into intracellular mechanical energy, generating heat.
Radiofrequency ablation for treatment of renal tumors: technological principles and outcomes. Radiofrequency ablation (RFA) is a minimally invasive, energy-based, needle-ablative treatment modality that is currently being used to treat small renal masses (SRMs) and offers advantages over extirpative techniques. RFA treats SRM with heat induced by the tissue impedance to radiofrequency current emitted from a needle probe within the SRM.
Another example of radiation therapy is the use of External Beam Radiation and Brachytherapy for Mesothelioma. Accelerated Partial Breast Irradiation (APBI) also uses brachytherapy: Beating breast cancer - Targeted radiation shortens treatment, reduces side effects.

Introduction to Raman Spectroscopy.
Vibrational spectroscopy: a tool being developed for the noninvasive monitoring of wound healing. Vibrational spectroscopy, specifically Raman and Fourier transform infrared spectroscopy, offers the capability to accurately detect and identify the various molecules that compose the extracellular matrix during wound healing in their native state. The identified changes might provide the objective markers of wound healing, which can then be integrated with clinical characteristics to guide the management of wounds.
Application of Raman spectroscopy for visualizing biochemical changes during peripheral nerve injury in vitro and in vivo.

Shockwave therapy is a relatively new treatment option in orthopedic and rehabilitation medicine. Shockwaves (high frequency sound waves) are used to treat many orthopedic conditions, including plantar fasciitis (heel spurs), patellar tendinitis (jumper’s knee), lateral epicondylitis (tennis elbow), medial epicondylitis (golfer’s elbow) and shoulder tendinitis. Multiple studies have been conducted to assess the efficacy of shockwave therapy. Many have shown a positive response versus placebo treatment and others have shown no benefit over placebo. No studies have reported any significant side effects when utilized for orthopedic conditions. However, there are some orthopedic conditions for which this technology is contraindicated.

The case for over-the-counter shortwave therapy: safe and effective devices for pain management. Pulsed shortwave diathermy, an electromagnetic therapy, has been in clinical use for acute and chronic musculoskeletal pain for many decades. Innovation, miniaturization and advances in technology have allowed for the development of a new generation of shortwave devices that deliver a localized, low fixed dose of shortwave therapy. Clinical research has shown that these novel shortwave devices can be used safely in order to reduce acute and chronic pain, as well as the need for pain medications. Their ease of use and safety profile make low-dose shortwave devices an attractive alternative, or adjunct therapy, to pharmacological-based pain therapies.

The potential of terahertz imaging for cancer diagnosis: A review of investigations to date. The terahertz region lies between the microwave and infrared regions of the electromagnetic spectrum such that it is strongly attenuated by water and very sensitive to water content. Terahertz radiation has very low photon energy and thus it does not pose any ionization hazard for biological tissues. Because of these characteristic properties, there has been an increasing interest in terahertz imaging and spectroscopy for biological applications within the last few years and more and more terahertz spectra are being reported, including spectroscopic studies of cancer. The presence of cancer often causes increased blood supply to affected tissues and a local increase in tissue water content may be observed: this acts as a natural contrast mechanism for terahertz imaging of cancer. Furthermore the structural changes that occur in affected tissues have also been shown to contribute to terahertz image contrast. This paper introduces terahertz technology and provides a short review of recent advances in terahertz imaging and spectroscopy techniques. In particular investigations relating to the potential of terahertz imaging and spectroscopy for cancer diagnosis will be highlighted.

New Therapy for Depression. A type of brain stimulation caused by a mild electric current that appears to have minimal negative side effects is showing promise as a potential treatment for major depression, according to several studies. The experimental therapy, known as transcranial direct current stimulation, or tDCS, involves a low-level charge about one-400th of that used in electroshock treatment. Unlike electroshock (also called electroconvulsive therapy or ECT), which is administered for a few seconds to patients under anesthesia, tDCS is given for 20 to 30 minutes continuously while patients are conscious.

Used for treating nerve disorders such as knee osteoarthritis and managing pain. One criticism of TENS is that its effects are often temporary. See Healing with Electromedicine and Sound Therapies (especially the 'Frequency Specific Microcurrent' section) for a more in-depth discussion. Recent research suggests that TENS over acupoints on lung function and dyspnoea in patients with chronic obstructive pulmonary disease warrants further investigation. For more information, see the Qigong and Energy Medicine Database™.
Chinese researchers confirm effectiveness of transcutaneous auricular vagus nerve stimulation for drug-resistant epilepsy. Transcutaneous Vagus Nerve Stimulation (t-VNS) uses the fact that a branch of the vagus nerve in the outer ear can be stimulated through the skin (transcutaneous) with electrical impulses. This stimulation passes along particular nerve fibers to reach the brainstem to consecutively activate higher centers of the brain associated with an anticonvulsive (anti-seizure) effect.

‘Good Vibrations’! Brain Ultrasound Improves Mood. A group from the Departments of Anesthesiology and Radiology at the University of Arizona Medical Center in Tucson, Arizona has investigated Transcranial Ultrasound (TUS) for modulating mental states in a pilot study in human volunteers suffering from chronic pain.They found improvement in subjective mood 10 min and 40 min after TUS compared to placebo. TUS can have safe neurophysiological effects on brain function, and is a promising noninvasive therapy for modulating conscious and unconscious mental states and disorders. They suggest TUS acts via intra-neuronal microtubules, which apparently resonate in TUS megahertz range.
The Role of Endobronchial Ultrasound in Lung Cancer Diagnosis and Staging: A Comprehensive Review. Endobronchial ultrasound (EBUS) technology is a relatively new bronchoscopic method of visualizing the tracheobronchial tree, the surrounding pulmonary parenchyma, and the mediastinal structures, with a particular role in lung cancer diagnosis, staging, and treatment.
Endobronchial Ultrasound (EBUS) Biopsy of Mediastinal Lymph Nodes. Mediastinoscopy is the ‘gold standard’ method for determining the presence of nodal metastases in the mediastinum. Generally performed as an outpatient surgical procedure, it is associated with a low rate of serious adverse effects (<1%) and the procedure is highly accurate, with false negative rates reported to be between 6% and 9%. Endobronchial ultrasound (EBUS) guided fine needle aspiration biopsy of mediastinal nodes offers a less invasive alternative for histologic sampling of the mediastinal nodes. The procedure has been widely adopted by pulmonologists and is poised to replace mediastinoscopy in the future. For thoracic surgeons, the technique can be easily learned and it may be important to do so if our specialty is to maintain its traditional and important role in the diagnosis and staging of thoracic malignancies.

Low-pressure pulsed focused ultrasound with microbubbles promotes an anticancer immunological response. High-intensity focused-ultrasound (HIFU) has been successfully employed for thermal ablation of tumors in clinical settings. Continuous- or pulsed-mode HIFU may also induce a host antitumor immune response, mainly through expansion of antigen-presenting cells in response to increased cellular debris and through increased macrophage activation/infiltration. Here we demonstrated that another form of focused ultrasound delivery, using low-pressure, pulsed-mode exposure in the presence of microbubbles (MBs), may also trigger an antitumor immunological response and inhibit tumor growth.

Biophoton transfer along the nerves of rats has been demonstrated experimentally. Different spectral light stimulation (infrared, red, yellow, blue, green and white) at one end of the spinal sensory or motor nerve roots resulted in a significant increase in the biophotonic activity at the other end. Such effects could be significantly inhibited by procaine (a regional anaesthetic for neural conduction block) or classic metabolic inhibitors, suggesting that light stimulation can generate biophotons that conduct along the neural fibers, probably as neural communication signals. The mechanism of biophotonic conduction along neural fibers may be mediated by protein-protein biophotonic interactions.
