Wolfram syndrome, also called DIDMOAD (diabetes insipidus, diabetes mellitus, optic atrophy, and deafness), is a rare autosomal-recessive genetic disorder that causes childhood-onset diabetes mellitus, optic atrophy, and deafness as well as various other possible disorders including neurodegeneration.
The number of new cases of diabetes insipidus each year is 3 in 100,000. [4] Central DI usually starts between the ages of 10 and 20 and occurs in males and females equally. [2] Nephrogenic DI can begin at any age. [3] The term "diabetes" is derived from the Greek word meaning siphon. [6]
A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
Long-term follow-up studies have shown that MCTD can progress to a moderate disease with a favorable prognosis, or patients can acquire a significant condition with vascular alterations driven by pulmonary hypertension and increased mortality. Approximately one-third of people with MCTD have a benign course and go into remission, while the ...
Pyomyositis is most common in tropical areas but can also occur in temperate zones. Pyomyositis can be classified as primary or secondary. Primary pyomyositis is a skeletal muscle infection arising from hematogenous infection, whereas secondary pyomyositis arises from localized penetrating trauma or contiguous spread to the muscle. [1]
Craniopharyngioma, germinoma, pinealoma, glioma, and meningioma can all cause central diabetes insipidus. [10] Trauma - Central diabetes insipidus can be caused by head trauma that affects the posterior pituitary and hypothalamus. [16] Vascular disorders - Vascular disorders such as subarachnoid hemorrhage, intracranial hemorrhage, and Sheehan ...
Both cause excessive urination (hence the similarity in name), but whereas diabetes insipidus is a problem with the production of antidiuretic hormone (neurogenic diabetes insipidus) or the kidneys' response to antidiuretic hormone (nephrogenic diabetes insipidus), diabetes mellitus causes polyuria via osmotic diuresis, due to the high blood ...
