The relationship between mercury from dental amalgam and mental health

Article Abstract:

In the last century, hat makers who were exposed to mercuric nitrate often exhibited symptoms of mental illness, which included irritability, excitability, and shyness, earning them the name ''Mad Hatters.'' Since that time, the relationship between mercury toxicity and health problems, both physical and mental, has been well documented. Dental amalgam, or ''silver fillings,'' is used to fill 80 percent of the dental cavities in the world. This substance contains up to 50 percent mercury. Thus, it was hypothesized that there may be a relationship between dental fillings and mental health. It was also theorized that mercury in this form may enter the brain in cumulatively toxic levels through inhalation and by absorption into the cranial veins. One hundred one subjects were studied to determine the relationship between the presence of mercury amalgam fillings and mental health status. Half of the group had amalgam, while 51 had no fillings. The hair and urine of the subjects was monitored for the presence of mercury, and the subjects were given two questionnaires regarding levels of stress tolerance, physical health, and emotional or psychological symptoms such as anger or depression. Those in the amalgam group were found to have twice as much mercury in their urine and 26.5 percent more in their hair samples as the nonamalgam group. In addition, the subjects with fillings rated their reading comprehension significantly lower, and had significantly more episodes of sudden anger, depression, and irritability. In a separate, uncontrolled questionnaire given to dental patients who had their fillings removed, 67 percent claimed to have improved psychological status. Mercury has been related to stress, fatigue, premenstrual syndrome, and loss of short term memory. It is recommended that psychotherapists consider the possibility of mercury toxicity as a causative factor in disorders ranging from mild stress-related complaints to schizophrenia.

The relationship between job security and employee health

Article Abstract:

A study of two manufacturing companies, one bureaucratically managed and the other owned jointly by employees and management, indicates that job security is important to employee health and that the degree of job security is directly related to employee health. Less job security is manifested in greater incidences of poor health. Increased job security, by lowering stress, is directly related to good health. The inclusion of this correlation into models of job stress and health can increase the understanding of the dynamics of work performance.

Ben Karpman, M.D.: 'Insecurity in search of security'

Article Abstract:

Ben Kapman's assumptions on the prevalence of insecurity in the different stages of human life were considered as one of the first studies in ego psychology and narcissistic disorders. Kapman's essay on emotional insecurity in 1951 dealt with the origin and epigenesis of emotional disorders. However, lack of information on the works of Kapman on psychopathology has affected further research into his studies on psychopathology.
