Radiation Effects of Mobile Phones and Tablets on the Skin: A Systematic Review

Background. Skin health has become a worldwide concern. Most of the studies investigated the effect of mobile phone radiation on DNA and animals, but a few studies were carried out about skin diseases in mobile phone and tablet users. Few systematic studies have examined the relationship between mobile phone exposure and skin diseases. Methods. We evaluated the association between mobile phones and tablets and skin diseases. We checked databases including PubMed, Scopus, Springer, Cochrane, and Google Scholar from 1995 to 2013. The eligibility criteria were descriptive, and observational studies were in English and Persian language, and the subjects were of all ages and reported skin disease. Results. Most of the studies focused on signs and less on skin cancer. In total, 6 studies were included with 392119 participants with age over 25 years. In a nationwide cohort study in Denmark for BCC, the IRR (incidence rate ratios) estimates remained near unity among men and women. In the other studies, they reported an increase in temperature, hypersensitivity of warmth, facial dermatitis, angiosarcoma of the scalp, and burning sensations in the facial skin after mobile phone use on the exposed side and more within the auricle and behind/around the ear. Conclusions. Overall evaluations showed that the level of evidence associated with the effects of radiation from the mobile phone and tablet on the skin is poor. This review shows a necessity for more studies in this area

The effect of presence of midwife (Doula) on anxiety and fear of natural childbirth in pregnant women: Randomized Clinical Trial

Introduction: Anxiety and fear of childbirth is one of the biggest concerns of pregnant women that may lead to the pain and prolonged delivery.

Results: There were no significant differences between the two group regarding individual socio-demographic, midwifery, the mean score of anxiety and fear of childbirth at the time of entering the delivery ward (P>0.05). The presence of a doula significantly reduced the mean score of anxiety and fear of childbirth in the active phase of labor and one hour after placental remove in the intervention group compared with the control group (P<0.001). Conclusion: The presence of doula in the delivery wards as a simple and non-invasive intervention can reduces anxiety and fear of natural childbirth in pregnant women. © 2022, Mashhad University of Medical Sciences.
