The effects of electromagnetic fields (EMFs) in physiotherapy have been discussed mainly with regard to the patient's safety, while the operator's safety is neglected. This paper presents the medical assessment and specific tendencies in the health status of personnel in physical therapy wards--where the EMFs are everyday background factor. This paper summarizes the somatic part of results from the study among physiotherapy personnel from facilities with different equipment and work load by using survey card designed by us for health status screening in somatic and neurobehavioral aspects. The main specific somatic findings and complaints in investigated group include parodontosis--42%; cardiovascular disorders--41.6%; allergic conditions with skin or systemic manifestation--40.8%; photosensibilization-- 34.1%; skin diseases--31.5%; musculoskeletal disorders--30.0% and neoplasm disorders--7.5%. Keeping in mind that better part of the personnel in the physical therapy units is female, a special attention was paid to the pathology of the reproductive system; menstrual disturbances are observed in 20.0%. These findings are collected in complex for the first time in physiotherapy personnel, and when data were available from other professional groups, we found a good correlation.

The exposure conditions in the physiotherapy are characterized with various sources emitting electromagnetic fields (EMF) in different frequency ranges. Very little is known about the exposure modalities' influence on the operators. In this article, we present the effects of EMF on personnel morbidity profile dependent on the body mass index (BMI) increase. By cross-tabulation, the role of higher BMI on enhancing the EMF vulnerability potential is confirmed. The correlation of the higher BMI with some serious diseases and conditions' development has been evidenced statistically significant. Вy the whole-studied group, a general tendency for allergy, cardiovascular diseases, sleep disruption and age-shortened menopause, as well as allergy and leiomyoma in the expositional criteria subgroups (ESG), formed for the purposes of this study, is evidenced. The three ESGs are formed on work residence duration in the electrolight therapy section. The first - up to four working hour daily, the second - the entire working day (7 h) and the third group is not residenced in the electrolight therapy section. We hypothesize two signaling ways of interaction of the chronically low-intensity EMF and the higher BMI as the most likely: hormonal - by melatonin levels decrease due to estrogen levels increasing and endocrine - mast-cells auto replication and degranulation stimulation. Based on the results of the study, the BMI increase as an observed control factor in the prediction of the professional risk can be recommended.

The importance of the assessment of the electromagnetic fields /EMF/ background as a health risk factor for the physiotherapy personnel is discussed in this paper. Wide frequency and amplitude ranges as well as large variety of design prescribed in the rehabilitation program form complicated work conditions. In this paper, we attempt to present and classify this specific work environment, i.e., low intensive EMF background with non homogenous frequency and modulation characteristics, stochastic changes running during day, ground or even underground units' placement and professional specifics, i.e., chronic EMF expositions, personnel's trunk and hands exposure, dose-measurement absence, lack of program for prevention and prophylaxis for the assessment of the relatively insufficiently elucidated potential of EMF as a harmful factor for medical staff. Our ''Study of the biological effects of the EMF among medical staff from PRM wards-potential of risk reduction''/initialized in 1999/and the original survey card structure are presented in general here first. It has been shown the importance to extend the ''native'' studies among homogenous professional groups, two of them presented there, as well as the study of the biological effects of EMF in their different aspects, especially taking into account the elevated levels of ionizing and non-ionizing radiation in the environment. This includes the special attention on the exposure of medical staff from PRM units and creation of adequate methods for prevention of unnecessary exposure to these physical factors.

Ferro-Magnetic nanoparticles (Fe-MNP) have gained a lot of attention in biomedical and industrial applications due to their biocompatibility, ease of surface modification and paramagnetic properties. The basic idea of our study is whether it is possible to use glucose-conjugate Fe-MNP (Glc-Fe-MNP) for targeting and more accurate focusing in order to increase the effect of high-frequency electromagnetic fields induced hyperthermia in solid tumors. Tumors demonstrate high metabolic activity for glucose in comparison with other somatic cells.Increasing of accumulation of glucose conjugated (Glc)-Fe-MNP on tumor site and precision of radio frequency electro-magnetic field (RF-EMF) energy absorption in solid tumors, precede RF-EMF induced hyperthermia. Rat model for monitoring the early development of breast cancer. Twenty female Wistar rats (MU-line-6171) were divided into two groups of 10 rats that were either treated with N-methyl-N-nitrosourea to induce breast cancer and 10 with carrageenan to induce inflammation (control). Glc-Fe-MNP can offer a solution to increase hyperthermia effect to the desired areas in the body by accumulation and increasing local concentration due to high tissue metabolic assimilation. In this condition, it is considered that the magnetization of the nanoparticles is a single-giant magnetic moment, the sum of all the individual magnetic moments and is proportional to the concentration of Glc-Fe-MNP.
