Electromagnetic radiation, which is used by broadcasting and mobile telephone systems to transmit information, permeates the city environment. In order to properly evaluate population exposure to electromagnetic fields, knowledge of their intensity and spectral components is necessary. In this study the results of radiofrequency field monitoring carried out in Torino, a large town located in the north-west of Italy are shown: the variation of the electromagnetic field strength is evaluated as a function of the height from the ground, the location in the urban area and the frequency. separating the contributions of the different sources (broadcasting antennas and radio base stations for mobile phones). Furthermore, the contribution of the radio base stations is theoretically evaluated, adding the emissions off all installations situated in Torino and examining the field strength maps calculated, considering the orography, for different heights. The theoretical values are also compared with those measured in the frequency range of mobile telephony emissions.
What are the novel findings of this work?In our series of uterine myomas with high vascularization on ultrasound, the histological diagnosis was benign in 93% of cases, which included leiomyoma variant in 45% and adenomyoma in 6%. A malignant lesion was diagnosed in 7% of cases, all of which occurred in patients over 40 years of age.
What are the clinical implications of this work?Our findings are useful in the clinical management of patients with a highly vascularized myoma identified during ultrasound assessment. Patients under 40 years of age can be managed conservatively (expectant or minimally invasive surgical management), whereas those over 40 years with a lesion that has irregular borders and without visible endometrium are at higher risk of malignancy and should preferably be managed by surgical oncologists.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
