Recessive Defect

Adult metachromatic leucodystrophy (MLD) is a rare demyelinating disease of the central nervous system caused by a genetic autosomal recessive defect and mediated through a deficiency in the enzyme arylsulphatase A (Peiffer, 1970). The initial manifestation may take the form of symptoms suggestive of schizophrenia or dementia (Sourander et al, 1962; Austin et al, 1968).

Acute disseminated encephalomyelitis (ADEM) is a rare immune-mediated inflammatory and demyelinating disorder of the central nervous system. Its characteristic perivenular demyelination and inflammation aid in the differential diagnosis with other inflammatory demyelinating diseases. Here, we present a clinical case of ADEM, summarize its histological hallmarks, and discuss pitfalls concerning the most important neuropathological differential diagnoses.

The Central Nervous System

The integrity of myelin sheaths is maintained by oligodendrocytes and Schwann cells respectively in the central nervous system (CNS) and in the peripheral nervous system. The process of demyelination consisting of the withdrawal of myelin sheaths from their axons is a characteristic feature of multiple sclerosis, the most common human demyelinating disease. Many experimental models have been designed to study the biology of demyelination and remyelination (repair of the lost myelin) in the CNS, due to the difficulties in studying human material. In the ethidium bromide (an intercalating gliotoxic drug) model of demyelination, CNS remyelination may be carried out by surviving oligodendrocytes and/or by cells differentiated from the primitive cell lines or either by Schwann cells that invade the CNS. However, some factors such as the age of the experimental animals, intensity and time of exposure to the intercalating chemical and the topography of the lesions have marked influence on the repair of the tissue.

The Central Nervous System

Canine distemper is a systemic infection, frequently lethal in dogs. The canine distemper virus(CDV) causes a persistent infection within the central nervous system resulting in aprogressive, multifocal demyelinating disease. In dogs, CDV infection may lead togastrointestinal and/or respiratory signs, frequently with central nervous system involvement.Myoclonus has been a common and characteristic sign observed in dogs with distemperencephalomyelitis. However, the nervous form of distemper may occur in the absence ofmyoclonus and systemic involvement. This review will point the clinical course and theneurological signs of nervous distemper, as well the clinical syndromes of CDV infection,neuropathology of acute and chronic demyelination, and diagnostic aids of CDVencephalomyelitis.

The involvement of central nervous system in children with typhoid fever is common. Acute disseminated encephalomyelitis is a rare immune mediated and demyelinating disease of the central nervous system that usually affects children. We report a 7-year-old child with typhoid fever who developed acute cerebellar syndrome due to acute disseminated encephalomyelitis.Journal of College of Medical Sciences-Nepal, 2013, Vol-9, No-4, 55-58 DOI: http://dx.doi.org/10.3126/jcmsn.v9i4.10237

Different Cell Types

There are 8 different types of diseases of the mucopolysaccharides, each caused by a deficiency in one of 10 different enzymes involved in the degradation of glycosaminoglycans (GAGs). Partially degraded GAGs accumulate within the lysosomes of many different cell types and lead to clinical symptoms and excretion of large amounts of GAGs in the urine. Heritability is autosomal recessive except for MPS type II, which is X-linked. The disorders are chronic and progressive and, although the specific types all have their individual features, they share an abundance of clinical similarities. All involve the musculoskeletal, the cardiovascular, the pulmonary and the central nervous system.
