The damage in the second report fulfilled all pathological diagnostic criteria of MS and can therefore be classified as MS in its own right. The lesions were classified as pattern II in the Lucchinetti system. This case of human EAE also showed Dawson fingers.Using the confluent demyelination as barrier between MS and ADEM, some other reports about EAE in humans classify its effects as ADEM but not always. In Japanese patients exposed to rabies vaccine that contained neural tissue, the clinical presentation resembled ADEM more than MS but the lesions were like acute multiple sclerosis (Uchimura and Shiraki, 1957). Anti-TNF demyelination
Recent problems with monoclonal antibodies point to an involvement of tumor necrosis factor alpha in the multiple sclerosis onset. Specifically, a monoclonal antibody against TNF-α (adalimumab) has been reported to induce a MS-like diseaseAlso some experimental therapies for other diseases has produced MS artificially in patients. Specifically, monoclonal antibodies treating cancer like pembrolizumab and infliximab have been reported to produce MS artificially. Specific forms of EAE
Since the discovery of the four lucchinetti patterns, new EAE models have been published, specifically mimicking the patterns I and II. DTH-EAE for pattern I (T cell and macrophage-mediated delayed-type hypersensitivity) and fMOG-EAE for pattern II (antibody-mediated focal myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalitis)Also a model for pattern III lesions has been developed in which mitochondrial metabolism is impaired, resulting in a tissue energy deficiency, a mechanism later termed "virtual hypoxia". The demyelination, characterized by loss of myelin-associated glycoprotein, has been described as "hypoxia-like".
Ichthyosis hystrix is a group of rare skin disorders in the ichthyosis family of skin disorders characterized by massive hyperkeratosis with an appearance like spiny scales. This term is also used to refer to a type of epidermal nevi with extensive bilateral distribution. Types
Ichthyosis hystrix, Curth-Macklin type
The symptoms of ichthyosis hystrix Curth-Macklin are similar to epidermolytic hyperkeratosis (NPS-2 type) but there is no blistering and the hyperkeratosis is verrucous or spine-like. The hyperkeratosis is brown-grey in colour and is most obvious on the arms and legs. It is an autosomal dominant condition and can be caused by errors to the KRT1 gene. It is named after Helen Ollendorff Curth (1899-1982), a German-Jewish dermatologist, and Madge Thurlow Macklin (1893–1962), an American medical geneticist, and is one of the first syndromes named after two women. Ichthyosis hystrix, Lambert type
Also known as ichthyosis hystrix gravior or porcupine man. This disease is characterised by spiny scales which cover the entire body except the face, genitals, palms and soles. The only known cases were in Edward Lambert (known as the porcupine man) who was exhibited in front of the Royal Society in London in 1731 and three generations of his descendants. No cases of this disease are now known though some experts believe that it may have been a type of epidermolytic hyperkeratosis. From the history of the Lambert family the disease appears to have been an autosomal dominant condition.
