Autism And Vaccines
Extensive investigation into vaccines and autism spectrum disorder has shown that there is no relationship between the two, causal or otherwise, and that vaccine ingredients do not cause autism. The American scientist Peter Hotez researched the growth of the false claim and concluded that its spread originated with Andrew Wakefield's fraudulent 1998 paper, and that no prior paper supports a link. Despite the scientific consensus for the absence of a relationship and the retracted paper, the anti-vaccination movement at large continues to promote theories linking the two. A developing tactic appears to be the "promotion of irrelevant research san active aggregation of several questionable or peripherally related research studies in an attempt to justify the science underlying a questionable claim." The Centers for Disease Control and Prevention (CDC) published updated statistics on autism in children for the year 2020. It states that in the year 2000, there were 1 in 150 childr ...

Autism
Autism, also known as autism spectrum disorder (ASD), is a neurodevelopmental disorder characterized by differences or difficulties in social communication and interaction, a preference for predictability and routine, sensory processing differences, focused interests, and repetitive behaviors, which may include stimming. Formal diagnosis requires significant challenges in multiple domains of life, with characteristics that are atypical or more pronounced than expected for one's age and sociocultural context.(World Health Organization: International Classification of Diseases version 11 (ICD-11)): https://icd.who.int/browse/2024-01/mms/en#437815624 Motor coordination difficulties are common but not required for diagnosis. Autism is a spectrum disorder, resulting in wide variations in presentation and support needs, such as that between speaking and non-speaking populations. Increased estimates of autism prevalence since the 1990s are primarily attributed to broader c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autistic Enterocolitis
On 28 February 1998, a fraudulent research paper by physician Andrew Wakefield and twelve coauthors, titled "Ileal-lymphoid-nodular hyperplasia, non-specific colitis, and pervasive developmental disorder in children", was published in the British medical journal ''The Lancet''. The paper falsely claimed causative links between the measles, mumps, and rubella (MMR) vaccine and colitis and between colitis and autism. The fraud involved data selection, data manipulation, and two undisclosed conflicts of interest. It was exposed in a lengthy ''Sunday Times'' investigation by reporter Brian Deer, resulting in the paper's retraction in February 2010 and Wakefield’s being discredited and struck off the UK medical register three months later. Wakefield reportedly stood to earn up to US$43 million per year selling diagnostic kits for a non-existent syndrome he claimed to have discovered. He also held a patent to a rival vaccine at the time, and he had been employed by a lawyer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methylmercury
Methylmercury is an organometallic cation with the formula . It is the simplest organomercury compound. Methylmercury is extremely toxic, and its derivatives are the major source of organic mercury for humans. It is a bioaccumulative environmental toxicant with a 50-day half-life. Methylmercury (derived biologically from dimethylmercury) is the causative agent of the infamous Minamata disease. Methylmercury is designated as a "priority hazardous substance" according to the Directive on Environmental Quality Standards (Directive 2013/39/EU). Structure and chemistry "Methylmercury" is a shorthand for the hypothetical "methylmercury cation", sometimes written ''methylmercury(1+) cation'' or ''methylmercury(II) cation''. This functional group is composed of a methyl group Chemical bond, bonded to an atom of Mercury (element), mercury. Its chemical formula is (sometimes written as ). The Methylmercury compound has an overall charge of +1, with Hg in the +2 oxidation state. Methylmer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neurotoxin
Neurotoxins are toxins that are destructive to nervous tissue, nerve tissue (causing neurotoxicity). Neurotoxins are an extensive class of exogenous chemical neurological insult (medical), insultsSpencer 2000 that can adversely affect function in both developing and mature nervous tissue.Olney 2002 The term can also be used to classify endogenous compounds, which, when abnormally contacted, can prove neurologically toxic. Though neurotoxins are often neurologically destructive, their ability to specifically target neural components is important in the study of nervous systems. Common examples of neurotoxins include lead, ethanol (drinking alcohol), glutamate,Choi 1987 nitric oxide, botulinum toxin (e.g. Botox), tetanus toxin,Simpson 1986 and tetrodotoxin. Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive concentrations. Neurotoxins inhibit neuron control over ion concentrations ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethylmercury
Ethylmercury (sometimes ethyl mercury) is a cation composed of an organic CH3CH2— species (an ethyl group) bound to a mercury(II) centre, making it a type of organometallic cation, and giving it a chemical formula C2H5Hg+. The main source of ethylmercury is thimerosal. Synthesis and structure Ethylmercury (C2H5Hg+) is a substituent of compounds: it occurs as a component of compounds of the formula C2H5HgX where X = chloride, thiolate, or another organic group. Most famously X = the mercaptide group of thiosalicylic acid as in thiomersal. In the body, ethylmercury is most commonly encountered as derivatives with a thiolate attached to the mercury. In these compounds, Hg(II) has a linear or sometimes trigonal coordination geometry. Given the comparable electronegativities of mercury and carbon, the mercury-carbon bond is described as covalent. Toxicity The toxicity of ethylmercury is well studied. Like methylmercury, ethylmercury distributes to all body tissues, crossi ...

Antifungal
An antifungal medication, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others. Such drugs are usually obtained by a doctor's prescription, but a few are available over the counter (OTC). The evolution of antifungal resistance is a growing threat to health globally. Routes of administration Ocular Indicated when the fungal infection is located in the eye. There is currently only one ocular antifungal available: natamycin. However, various other antifungal agents could be compounded in this formulation. Intrathecal Used occasionally when there's an infection of the central nervous system and other systemic options cannot reach the concentration required in that region for therapeutic benefit. Example(s): amphotericin B. Vaginal This may be used to treat some fungal in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thiomersal
Thiomersal (International Nonproprietary Name, INN), or thimerosal (United States Adopted Name, USAN, Japanese Accepted Name, JAN), also sold under the name merthiolate, is an organomercury compound. It is a well-established antiseptic and antifungal agent. The pharmaceutical corporation Eli Lilly and Company named it Merthiolate. It has been used as a preservative in vaccines, immunoglobulin preparations, Allergy#Diagnosis, skin test antigens, antivenins, ophthalmology, ophthalmic and nasal products, and tattoo inks. In spite of the scientific consensus that fears about its safety are unsubstantiated, its use as a vaccine preservative has been Thiomersal controversy, called into question by vaccine hesitancy, anti-vaccination groups. A 1999 statement issued in Centers for Disease Control and Prevention, CDC's Morbidity and Mortality Weekly Report announced that "the Public Health Service (United States Public Health Service Commissioned Corps, PHS), the American Academy of Ped ...

National Health Service
The National Health Service (NHS) is the term for the publicly funded health care, publicly funded healthcare systems of the United Kingdom: the National Health Service (England), NHS Scotland, NHS Wales, and Health and Social Care (Northern Ireland) which was created separately and is often referred to locally as "the NHS". The original three systems were established in 1948 (NHS Wales/GIG Cymru was founded in 1969) as part of major social reforms following the Second World War. The founding principles were that services should be comprehensive, universal and free at the point of delivery. Each service provides a comprehensive range of health services, provided without charge for residents of the United Kingdom apart from dental treatment and optical care. In England, NHS patients have to pay prescription charges; some, such as those aged over 60, or those on certain state benefits, are exempt. Taken together, the four services in 2015–16 employed around 1.6 million people ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vaccine Court
The Office of Special Masters of the U.S. Court of Federal Claims, popularly known as "vaccine court", administers a no-fault system for litigating vaccine injury claims. These claims against vaccine manufacturers cannot normally be filed in state or federal civil courts, but instead must be heard in the U.S. Court of Federal Claims, sitting without a jury. The National Vaccine Injury Compensation Program (VICP or NVICP) was established by the 1986 National Childhood Vaccine Injury Act (NCVIA), passed by the United States Congress in response to a threat to the vaccine supply due to a 1980s scare over the DPT vaccine. Despite the belief of most public health officials that claims of side effects were unfounded, large jury awards had been given to some plaintiffs, most DPT vaccine makers had ceased production, and officials feared the loss of herd immunity. Between its inception in 1986 and May 2023, it has awarded a total of $4.6 billion, with the average award amount between ...
