A careful study by a group of investigators of the University of Giessen suggests that there is no indication for mercury intoxication or amalgam allergy as a cause of somatic complaints.
To deepen the understanding of the numerous unspecific complaints which are related to the dental material amalgam both in patients and physicians, an interdisciplinary case-control study regarding toxicological, allergic, psychological and psychiatric aspects was conducted. Forty patients with amalgam-associated complaints were compared to a well-matched group of 40 amalgam bearers without complaints. Patients and controls underwent a dental examination, which included recording of the quantity, surface area and quality of amalgam fillings, a determination of the mercury load in blood and urine, an allergy examination including patch testing with amalgam and a psychometric assessment with questionnaires noting coping strategies (ABI-UMW-P), interpersonal problems (Inventory of Interpersonal Problems) and self-consciousness (SAM), the NEO Five-Factor Inventory, Symptom Checklist-90-R, Beck Depression Inventory and a screening instrument for somatoform disorders. Patients and controls did not differ with respect to mercury concentrations in body fluids. Only 1 patient was found to have a positive amalgam patch test; various other allergies could be determined in 28% of patients (n = 11). Patients had higher levels of psychic distress, a higher incidence of depression and somatization disorders as well as different styles of coping with anxiety compared to controls. No indication for mercury intoxication or amalgam allergy as a cause of the patients` complaints could be found. The theory of amalgam-related complaints as an expression of underlying psychic problems is supported. Treatment should focus on somatization and changing coping and attribution styles

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
