TL;DR: Annoyance related to electrical and/or chemical factors was common in a Swedish population and the association with subjective health and functional capacity increased with severity of annoyance, which suggests that there is some connection between environmental annoyance, well-being andfunctional capacity.

TL;DR: The prevalence of symptoms in the Swedish population was found to accord with results in studies based on different kinds of samples, and SBS symptoms, skin symptoms, and symptoms similar to those reported by individuals with ``electric hypersensitivity'' were significantly more prevalent among employees with extensive VDU usage.
Abstract: Aims: Health problems associated with indoor environments have been reported and discussed extensively during the past few decades, not least in Sweden. There is, however, great uncertainty concerning the background prevalence of the symptoms in question. The main objective of the present study was to investigate the prevalence of general, mucosal, and skin symptoms in the Swedish population. Methods: A survey comprising 3,000 randomly selected Swedes, age 18—64, was carried out. The survey addressed 25 symptoms, principally general, mucosal, and skin symptoms. A number of other areas were covered and individual data registered at Statistics Sweden were added. The response rate was 70% (2,154 cases). Results: The prevalence of symptoms in the Swedish population was found to accord with results in studies based on different kinds of samples. Women reported significantly more single symptoms, as well as sets of symptoms, than men. There was no clear connection between age and symptoms. The prevalence of sym...

TL;DR: A summary of the knowledge on astroglial-neuronal interaction in glutamate neurotransmission is given in this article, focusing on the contribution of astroglia to synaptic dynamics.
Abstract: This is a summary of the knowledge on astroglial-neuronal interaction in glutamate neurotransmission, especially focusing on astroglial contributions to synaptic dynamics. It briefly addresses different topics such as membrane receptors and signal transduction systems on astroglia and the expression of some ion channels and glutamate carriers.

TL;DR: Facial skin from so‐called “screen dermatitis” patients were compared with corresponding material from normal healthy volunteers to evaluate possible markers to be used for future double blind or blind provocation investigations, and no single marker was 100% able to pin‐point the difference.
Abstract: In the present study, facial skin from so-called "screen dermatitis" patients were compared with corresponding material from normal healthy volunteers. The aim of the study was to evaluate possible markers to be used for future double-blind or blind provocation investigations. Differences were found for the biological markers calcitonin gene-related peptide (CGRP), somatostatin (SOM), vasoactive intestinal polypeptide (VIP), peptide histidine isoleucine amide (PHI), neuropeptide tyrosine (NPY), protein S-100 (S-100), neuron-specific enolase (NSE), protein gene product (PGP) 9.5 and phenylethanolamine N-methyltransferase (PNMT). The overall impression in the blind-coded material was such that it turned out easy to blindly separate the two groups from each other. However, no single marker was 100% able to pin-point the difference, although some were quite powerful in doing so (CGRP, SOM, S-100). However, it has to be pointed out that we cannot, based upon the present results, draw any definitive conclusions about the cause of the changes observed. Whether this is due to electric or magnetic fields, a surrounding airborne chemical, humidity, heating, stress factors, or something else, still remains an open question. Blind or double-blind provocations in a controlled environment are necessary to elucidate possible underlying causes for the changes reported in this investigation.

TL;DR: In this paper, a comparative study of 50 Hz electric and magnetic fields in houses and offices in Sweden and Norway has been carried out, and the mean levels determined in houses were as follows: E fields 54 V/m (SD=37) and 77 V/M (SD = 58) in Sweden, respectively; B fields 40 nT (SD>37).
Abstract: A comparative study of 50 Hz electric and magnetic fields in houses and offices in Sweden and Norway has been carried out. The local distribution systems in houses are often different in the two countries. Overall mean levels determined in houses were as follows: E fields 54 V/m (SD=37) and 77 V/m (SD=58) in Sweden and Norway respectively; B fields 40 nT (SD=37) and 13 nT (SD=17) respectively. The difference in the magnetic field levels is considered to reflect larger ground currents in Swedish houses. In offices the fields varied substantially. E fields were of the order of 40 V/m and 15 V/m in Sweden and Norway, while the B fields varied from some nT to over 1 /spl mu/T in both countries. Some reasons for the high office levels were safety ground errors and in-house magnetic field sources.

TL;DR: No sensitivity to electromagnetic fields could be objectively verified for this patient, who was suspected to suffer from a thoracic outlet syndrome.
Abstract: Background Many patients in Sweden are today distressed by fears of "electric fields." This phenomenon was almost unknown to occupational health clinics 10 years ago. Case history and examination A 35-year-old male plumber complained of fatigue, headache, lack of concentration, numbness and paresthesia in his arms, and a greasy feeling in his palms, where he observed tiny shiny spots. These symptoms made him unable to work. It all started after a period of high strain at the work. He feared negative influences, mainly from electric fields. Signs indicating nerve entrapment in the upper extremities were found in a clinical examination. Provocation study The patient was blindly provocated in a whole-body electromagnetic coil at 34 or 100 µT randomly mixed with sham exposures. After being blinded against irrelevant external cues, he was not able to detect the existence of or any symptoms at either field intensity. He was informed about the results and was later able to return to his previous work. Conclusions No sensitivity to electromagnetic fields could be objectively verified for this patient, who was suspected to suffer from a thoracic outlet syndrome.
