Other measures include a firm mattress separate from but close to caregivers, no loose bedding, a relatively cool sleeping environment, using a pacifier, and avoiding exposure to tobacco smoke. Breastfeeding and immunization may also be preventive. Measures not shown to be useful include positioning devices and baby monitors. Evidence is not sufficient for the use of fans. Grief support for families affected by SIDS is important, as the death of the infant is sudden, without witnesses, and often associated with an investigation.Rates of SIDS vary nearly tenfold in developed countries from one in a thousand to one in ten thousand. Globally, it resulted in about 19,200 deaths in 2015, down from 22,000 deaths in 1990. SIDS was the third leading cause of death in children less than one year old in the United States in 2011. It is the most common cause of death between one month and one year of age. About 90% of cases happen before six months of age, with it being most frequent between two months and four months of age. It is more common in boys than girls. Rates of SIDS have decreased in areas with "safe sleep" campaigns by up to 80%. Definition
The syndrome only applies to infants under one.
However, there is still controversy surrounding its efficacy. A simple way of reducing inflammation is to stop smoking, as pro-inflammatory substances are found in cigarettes. The medication teprotumumab-trbw may also be used. There is tentative evidence for selenium in mild disease. Tocilizumab, a drug used to suppress the immune system has also been studied as a treatment for TED. However, a Cochrane Review published in 2018 found no evidence (no relevant clinical studies were published) to show that tocilizumab works in people with TED.In January 2020, the US Food and Drug Administration approved teprotumumab-trbw for the treatment of Graves ophthalmopathy. Surgery
There is some evidence that a total or sub-total thyroidectomy may assist in reducing levels of TSH receptor antibodies (TRAbs) and as a consequence reduce the eye symptoms, perhaps after a 12-month lag. However, a 2015 meta review found no such benefits, and there is some evidence that suggests that surgery is no better than medication.Surgery may be done to decompress the orbit, to improve the proptosis, and to address the strabismus causing diplopia. Surgery is performed once the persons disease has been stable for at least six months. In severe cases, however, the surgery becomes urgent to prevent blindness from optic nerve compression. Because the eye socket is bone, there is nowhere for eye muscle swelling to be accommodated, and, as a result, the eye is pushed forward into a protruded position.
