Use of Pulsed Electro-Magnetic Therapy on Children Undergoing Orchidopexy. Ulcers (Gastric and Duodenal) Millimeter wave (MW) therapy in 317 patients suffering from duodenal and gastric ulcers. MW therapy consisted of 30 minutes per day exposure of the epigastric area apparatus,(10 mW/cm2, 5.6-mm wavelength) until complete ulcer cicatrisation was achieved. Results showed a 95-percent rate of ulcer cicatrisation in patients receiving the treatment. Extremely-high-frequency therapy to be an effective treatment in patients suffering from duodenal ulcers. Treatment consisted of 5-10 exposures, lasting 20-30 minutes, and making use of the G4-142 apparatus (53.5-70.0 GHz frequency range). M.V.

Pate K, Benghuzzi H, Tucci M, Puckett A, Cason Z. University of Mississippi Medical Center, Jackson, MS 39216, USA. The quality of tissue repair and the speed with which that repair can be accomplished are the two major variables in the healing of any injury. Today, magnetic field exposure to traumatized areas has shown to be a promising tool in the healing process. The exact mode of action by which radiating and unchanging magnetic fields still has to be elucidated. The objective of this study was to evaluate the morphology of MRC-5 fibro-blasts after stimulation with static and pulsating magnetic fields. Under sterile environment, a total of 24 wells were loaded with 50,000 MRC-5 cells each and further divided into three groups. Groups 1 and 2 were exposed to magnetic fields, static and pulsating respectively. Group 3 wells were unexposed and served as the control group. The cells were monitored at 0, 24, 48, and 72 hours and representative views were captured using digital analysis techniques. The live cells were screened for cellular mobility, cell distribution, and cellular morphology (size, shape, lysis, and background). After 72 hours, the supernatants and cells of all three groups were collected and MDA analysis was performed to determine possible cellular damage. Group 1 cells continued to grow at a reasonable rate, but there was substantial cell membrane damage (high MDA levels, p < 0.05). Group 2 cells appeared to be very stressed under these conditions especially at the initial phase (24 hours). In conclusion, the use of pulsating magnetic stimulation can be beneficial in the healing process of soft tissues. Biomed Sci Instrum. 2003;39:460-5.

Trock DH. Yale University School of Medicine, New Haven, Connecticut, USA. Certain pulsed electromagnetic fields (PEMF) affect the growth of bone and cartilage in vitro, with potential application as an arthritis treatment. PEMF stimulation is already a proven remedy for delayed fractures, with potential clinical application for osteoarthritis, osteonecrosis of bone, osteoporosis, and wound healing. Static magnets may provide temporary pain relief under certain circumstances. In both cases, the available data is limited. The mechanisms underlying the use of PEMF and magnets are discussed.

Quittan M, Schuhfried O, Wiesinger GF, Fialka-Moser V. Universitatsklinik fur Physikalische Medizin und Rehabilitation, Wien. michael.quittan@akh-wien.ac.at To verify the efficacy of electromagnetic fields on various diseases we conducted a computer-assisted search of the pertinent literature. The search was performed with the aid of the Medline and Embase database (1966-1998) and reference lists. Clinical trials with at least one control group were selected. The selection criteria were met by 31 clinical studies. 20 trials were designed double-blind, randomised and placebo-controlled. The studies were categorised by indications. Electromagnetic fields were applied to promote bone-healing, to treat osteoarthritis and inflammatory diseases of the musculoskeletal system, to alleviate pain, to enhance healing of ulcers and to reduce spasticity. The action on bone healing and pain alleviation of electromagnetic fields was confirmed in most of the trials. In the treatment of other disorders the results are contradictory. Application times varied between 15 minutes and 24 hours per day for three weeks up to eighteen months. There seems to be a relationship between longer daily application time and positive effects particular in bone-healing. Patients were treated with electromagnetic fields of 2 to 100 G (0.2 mT to 10 mT) with a frequency between 12 and 100 Hz. Optimal dosimetry for therapy with electromagnetic fields is yet not established. Acta Med Austriaca. 2000;27(3):61-8.

Vallbona C, Richards T. Department of Family and Community Medicine, Baylor College of Medicine, Houston, Texas, USA. Static or electromagnetic fields have been used for centuries to control pain and other biologic problems, but scientific evidence of their effect had not been gathered until recently. This article explores the value of magnetic therapy in rehabilitation medicine in terms of static magnetic fields and time varying magnetic fields (electromagnetic). A historical review is given and the discussion covers the areas of scientific criteria, modalities of magnetic therapy, mechanisms of the biologic effects of magnetic fields, and perspectives on the future of magnetic therapy. Phys Med Rehabil Clin N Am. 1999 Aug;10(3):729-54.

Jerabek J. National Institute of Public Health, Praha, Czech Republic. Pulsed magnetotherapy has been used in Czechoslovakia for more than one decade. It has been proved that this type of physical therapy is very efficient mainly in rheumatic diseases, in paediatrics (sinusitis, enuresis), and in balneological care of patients suffering from ischaemic disorders of lower extremities. Promising results have also been obtained in neurological diseases (multiple sclerosis, spastic conditions) and in ophthalmology, in degenerative diseases of the retina.
