The disease has also been reported affecting the commercial salmon fisheries of the United States, Australia, New Zealand, France, Spain, Ireland and Chile. [2] It was first diagnosed in the summer of 1984/1985 in populations of Atlantic salmon off the east coast of Tasmania and was found to be caused by N. perurans n.sp. [3] Contents 1 Clinical signs and diagnosis 2 Treatment and control 3 Notes 4 References Clinical signs and diagnosis [ edit ] Symptoms typically begin to appear two months after the fish are transferred from freshwater hatcheries to open net sea cages. [4] Symptoms include mucus build-up on the gills of infected fish and hyper-plastic lesions, causing white spots and eventual deterioration of the gill tissue. ... Treatment and control [ edit ] Currently, the most effective treatment is transferring the affected fish to a freshwater bath for a period of 2 to 3 hours. This is achieved by towing the sea cages into fresh water, or pumping the fish from the sea cage to a tarp filled with fresh water. [6] Mortality rates have been lowered by adding levamisole to the water until the saturation is above 10ppm. ... searchQuery=amoebic+gill+disease&moduleId=2708303&moduleFilter=&categoryFilter=&startAt=0 [ permanent dead link ] ^ "Neoparamoeba perurans n. sp., an agent of amoebic gill disease of Atlantic salmon (Salmo salar)". ... searchQuery=amoebic+gill+disease&moduleId=2708303&moduleFilter=&categoryFilter=&startAt=0 [ permanent dead link ] ^ https://www.int-res.com/articles/dao/25/d025p023.pdf ^ http://eafp.org/display/Search?searchQuery=amoebic+gill+disease&moduleId=2708303&moduleFilter=&categoryFilter=&startAt=0 [ permanent dead link ] References [ edit ] Amoebic Gill Disease Wikivet .

Poikiloderma vasculare atrophicans Other names Parapsoriasis variegata [1] or Parapsoriasis lichenoides [2] Typical skin changes and discoloration described as poikiloderma vasculare atrophicans Specialty Dermatology Poikiloderma vasculare atrophicans ( PVA ), is a cutaneous condition ( skin disease ) characterized by hypo- or hyperpigmentation (diminished or heightened skin pigmentation , respectively), telangiectasia and skin atrophy . [3] [4] [5] Other names for the condition include prereticulotic poikiloderma and atrophic parapsoriasis . [6] The condition was first described by pioneer American pediatrician Abraham Jacobi in 1906. [7] PVA causes areas of affected skin to appear speckled red and inflamed, yellowish and/or brown, gray or grayish-black, with scaling and a thinness that may be described as "cigarette paper". [3] On the surface of the skin, these areas may range in size from small patches, to plaques (larger, raised areas), to neoplasms (spreading, tumor-like growths on the skin). [3] [6] Mycosis fungoides, a type of skin lymphoma , may be a cause of PVA. The condition may also be caused by, associated with or accompany any of the following conditions or disorders: other skin lymphomas, dermatomyositis , lupus erythematosus , Rothmund–Thomson syndrome , Kindler syndrome , dyskeratosis congenita , and chronic radiodermatitis . [4] Rare causes include arsenic ingestion, and the condition can also be idiopathic . [1] [3] [5] PVA may be considered a rare variant of cutaneous T-cell lymphoma , a non-Hodgkin's form of lymphoma affecting the skin. [7] It may also be included among a number of similar conditions that are considered as precursors to mycosis fungoides . PVA is believed to be a syndrome closely associated with large-plaque parapsoriasis and its cohort retiform parapsoriasis ; including PVA, all three conditions fit within an updated view of the once ambiguous classification scheme known as parapsoriasis .

Abnormal depolarizations of cardiac myocytes Afterdepolarizations are abnormal depolarizations of cardiac myocytes that interrupt phase 2, phase 3, or phase 4 of the cardiac action potential in the electrical conduction system of the heart . ... Early afterdepolarizations [ edit ] Early afterdepolarizations (EADs) occur with abnormal depolarization during phase 2 or phase 3, and are caused by an increase in the frequency of abortive action potentials before normal repolarization is completed. Phase 2 may be interrupted due to augmented opening of calcium channels , while phase 3 interruptions are due to the opening of sodium channels . ... They are due to elevated cytosolic calcium concentrations, classically seen with digoxin toxicity. [3] [4] The overload of the sarcoplasmic reticulum may cause spontaneous Ca 2+ release after repolarization, causing the released Ca 2+ to exit the cell through the 3Na + /Ca 2+ -exchanger. This results in a net depolarizing current. The classical feature is Bidirectional ventricular tachycardia .
Human African Trypanosomiasis (HAT), also called sleeping sickness, is a vector-borne parasitic disease caused by a protozoa of the Trypanosoma genus transmitted by the bite of a tsetse fly (genus Glossina ), that is found under its chronic form (average duration of 3 years) in western and central Africa (in case of the T. brucei gambiense sub-species), and under its acute form (lasting from few weeks to 6 months) in eastern and southern Africa (in case of the T. brucei rhodesiense sub-species).
Other probabilities for the other possible allele combinations concerning this gene are: 0% chance of affected offspring if only one parent is a carrier, 0% chance of affected offspring if one parent is affected and the other does not carry the allele, and 50% chance of affected offspring if one parent is affected and the other is a carrier. ...

Glycogen storage disease type 0 (also known as GSD 0) is a condition caused by the body's inability to form a complex sugar called glycogen, which is a major source of stored energy in the body. GSD 0 has two types: in muscle GSD 0, glycogen formation in the muscles is impaired, and in liver GSD 0, glycogen formation in the liver is impaired. The signs and symptoms of muscle GSD 0 typically begin in early childhood. ... Because some people with muscle GSD 0 die from sudden cardiac arrest early in life before a diagnosis is made and many with liver GSD 0 have mild signs and symptoms, it is thought that GSD 0 may be underdiagnosed. Causes Mutations in the GYS1 gene cause muscle GSD 0, and mutations in the GYS2 gene cause liver GSD 0.
A number sign (#) is used with this entry because of evidence that liver glycogen storage disease-0 (GSD0A) is caused by homozygous or compound heterozygous mutation in the GYS2 gene (138571), which encodes glycogen synthase-2, on chromosome 12p12. ... Gitzelmann et al. (1996) described 3 children with liver glycogen synthase deficiency from 2 German families and compared the observations with the previously published 3 families comprising 8 patients. ... In the first year of life she ate every 3 to 4 hours and never slept through the night, awakening spontaneously to feed. ... Mapping Orho et al. (1998) established linkage of glycogen storage disease 0 to intragenic and flanking polymorphic markers of the GYS2 gene on chromosome 12p12.2. Molecular Genetics In affected members of 5 families with liver glycogen storage disease 0, Orho et al. (1998) identified homozygous or compound heterozygous mutations in the GYS2 gene (138571.0001-138571.0008) Inheritance - Autosomal recessive Neuro - Seizures Lab - Glycogen synthetase deficiency Metabolic - Neonatal hypoglycemia - Fasting hypoglycemia - Fasting hyperketonemia - Hyperglycemia and hyperlactatemia with feeding ▲ Close
A genetically inherited anomaly of glycogen metabolism and a form of glycogen storage disease (GSD) characterized by fasting hypoglycemia. This is not a glycogenosis, strictly speaking, as the enzyme deficiency decreases glycogen reserves. Epidemiology It is an extremely rare disease; about 20 cases have been reported in the literature so far. Clinical description It commonly appears in infancy or in early childhood. Patients present with morning fatigue and fasting hypoglycemia (without hepatomegaly) associated with hyperketonemia but without hyperalaninemia or hyperlactacidemia.
Glycogen storage disease type 0, liver (liver GSD 0), a form of glycogen storage disease (GSD), is a rare abnormality of glycogen metabolism (how the body uses and stores glycogen, the storage form of glucose). Unlike other types of GSD, liver GSD 0 does not involve excessive or abnormal glycogen storage, and causes moderately decreased glycogen stores in the liver. ... This condition differs from another form of GSD 0 which chiefly affects the muscles and heart ( Glycogen storage disease type 0, muscle ) and is thought to be caused by mutations in the GYS1 gene.

Clinical Features Cady and Trotter (1920) reported 3 unrelated families with ringed hair. ... In addition, individuals with pili annulati usually have normal growth of hair, whereas those with monilethrix have alopecia as well as associated follicular keratosis. Inheritance In 3 families with ringed hair reported by Cady and Trotter (1920), the transmission pattern was consistent with autosomal dominant inheritance.
Pili annulati is a hair disorder. In pili annulati, affected hair has a pattern of light and dark banding. People with pili annulati may describe their hair as "striped" or as having silvery beads. Pili annulati typically involves 20-80% of scalp hair, however it can involve facial and body hair as well. Affected hairs may be more prone to breakage. Pili annulati can present in infancy, childhood, or later in life. It can be seen with the naked eye, however it may be more difficult to see in people with dark hair.
Pili annulati is an isolated, benign hair shaft abnormality, usually presenting after the age of 2 and affecting the hair of the scalp or very rarely beard, axillary, or pubic hair, that is characterized by a banded or speckled appearance due to alternating light bands (corresponding to air-filled cavities within the cortex of the affected hair shafts) and dark bands. The bands have a lifelong duration, may only be detectable under light microscopy, are more apparent in fair-colored hair or with age-related graying, and have no effect on hair growth or fragility in the vast majority of cases.

Pili torti is a hair shaft abnormality characterized by flat hair that is twisted at irregular intervals. Hair is normal at birth but progressively stops growing long and becomes fragile. Pili torti can be isolated or occur in association with syndromes such as Menkes disease or Bazex syndrome (see these terms).
Description Pili torti, or twisted hair, is a condition in which the hair shafts are flattened and rotated along their long axis. Hairs are fragile and break at short length.

Some cases may be inherited in autosomal dominant or autosomal recessive patterns, while others are acquired. In the inherited form, symptoms tend to be present from early childhood. It can occur alone or as part of other diseases like ectodermal dysplasias , Menke disease , Bjornstand syndrome , or Bazex syndrome . Acquired cases of pili torti may be associated with anorexia nervosa , malnutrition, oral retinoid treatment, or inflammatory scalp conditions (e.g., cutaneous lupus erythematousus ).
