“…During the last decade, there has been published a large number of studies scrutinizing the quality of online information related to most if not any known disease or medical condition. Various authors conclude that the Internet is not a reliable source of information and does not accurately inform patients about coronary heart disease [28], cardiac murmurs [29], varicose veins and the treatment options [30], gastric cancer [31], breast cancer [32,33], head and neck cancers [34], oral cancer [35], prostate cancer [36], urological oncology [37], hemangiomas [38], menopause [39], diabetes mellitus [40,41], parathyroid disease [42], healthy nutrition [43,44], vitamin B12 [45], depression [46], epilepsy [47] rheumatological conditions [48], osteoporosis [49], first aid for burns [50,51], first aid in choking [52], cervical and lumbar disc herniation [53,54], scoliosis [55], vascular and other surgical operations [56,57], influenza [58], child fever [59], coeliac disease [60].
