A physical examination and laboratory investigations may disclose somatic illness complicating the obstetric events, which sometimes provokes psychosis. It is important to obtain the case records of previous episodes of mental illness, and, in patients with multiple episodes, to construct a summary of the whole course of her psychiatric history in relation to her life. In the 10th edition of the International Classification of Diseases, published in 1992, the recommendation is to classify these cases by the form of the illness, without highlighting the postpartum state. There is, however, a category F53.1, entitled severe mental and behavioural disorders associated with the puerperium, which can be used when it is not possible to diagnose some variety of affective disorder or schizophrenia. The American Psychiatric Associations Diagnostic and Statistical Manual, whose 5th edition was published in May 2013, allows the use of a peripartum onset specifier in episodes of mania, hypomania or major depression if the symptoms occur during pregnancy or the first four weeks of the puerperium. The failure to recognize postpartum psychosis, and its complexity, is unhelpful to clinicians, epidemiologists, and other researchers. Onset groups
Postpartum bipolar disease belongs to the bipolar spectrum, whose disorders exist in two contrasting forms – mania and depression. They are highly heritable, and affected individuals (less than 1% of the population ) have a lifelong tendency (diathesis) to develop psychotic episodes in certain circumstances. The triggers include a number of pharmaceutical agents, surgical operations, adrenal corticosteroids, seasonal changes, menstruation and childbearing.
In India, a study by Centre for Science and Environment and Indian Institute of Toxicology Research has found that in the countrys energy capital Singrauli, mercury is slowly entering peoples homes, food, water and even blood. The Minamata Convention on Mercury in 2016 announced that the signing of the "international treaty designed to protect human health and the environment from anthropogenic releases and emission of mercury and mercury compounds" on April 22, 2016—Earth Day. It was the sixtieth anniversary of the discovery of the disease. Infantile acrodynia
Infantile acrodynia (also known as "calomel disease", "erythredemic polyneuropathy", and "pink disease") is a type of mercury poisoning in children characterized by pain and pink discoloration of the hands and feet. The word is derived from the Greek, where άκρο means end or extremity, and οδυνη means pain. Acrodynia resulted primarily from calomel in teething powders and decreased greatly after calomel was excluded from most teething powders in 1954.Acrodynia is difficult to diagnose; "it is most often postulated that the etiology of this syndrome is an idiosyncratic hypersensitivity reaction to mercury because of the lack of correlation with mercury levels, many of the symptoms resemble recognized mercury poisoning." Medicine
Mercury was once prescribed as a purgative. Many mercury-containing compounds were once used in medicines. These include calomel (mercurous chloride), and mercuric chloride.
