Haemochromatosis is protean in its manifestations, i.e., often presenting with signs or symptoms suggestive of other diagnoses that affect specific organ systems.Many of the signs and symptoms below are uncommon, and most patients with the hereditary form of haemochromatosis do not show any overt signs of disease nor do they have premature morbidity, if they are diagnosed early, but, more ...
Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
Treatment of iron poisoning should be based on clinical presentation, peak serum iron levels and other laboratory results. As a general guideline, patients who have ingested lower doses of elemental iron, have a peak serum iron level less than 500mcg/dL and are asymptomatic or only exhibit mild gastrointestinal symptoms typically do not require ...
Toxicity occurs through overdosage with an appropriate product or use of an agricultural product. Signs for both include hypersalivation, vomiting, lethargy, tremors, difficulty walking, weakness, and death. [174] Chocolate is a common cause of poisoning in dogs. The toxic principles in chocolate are theobromine and caffeine.
Treatment is based on the symptoms and severity of the disease. Iron chelators may be used to bind excess iron in tissues and allow for excretion of the excess metal. [15] Individuals with hemochromatosis type 4B may be treated with therapeutic phlebotomy. However, individuals with hemochromatosis type 4A may not require treatment.
Metal toxicity or metal poisoning is the toxic effect of certain metals in certain forms and doses on life. Some metals are toxic when they form poisonous soluble compounds. Certain metals have no biological role, i.e. are not essential minerals, or are toxic when in a certain form. [ 1 ]
Trilostane was the first drug approved to treat both pituitary- and adrenal-dependent Cushing's in dogs. [citation needed] Only one other drug, Anipryl (veterinary brand name) selegiline, is FDA-approved to treat Cushing's disease in dogs, but only to treat uncomplicated, pituitary-dependent Cushing's. [30] The only previous treatment for the ...
The underlying mechanism involves some of the iron in hemoglobin being converted from the ferrous [Fe 2+] to the ferric [Fe 3+] form. [3] The diagnosis is often suspected based on symptoms and a low blood oxygen that does not improve with oxygen therapy. [3] Diagnosis is confirmed by a blood gas. [3]
