Avatar m tn Headache is the most common presenting complaint, occurring in more than 90 percent of cases. Dizziness, nausea, and vomiting may also be encountered, but typically there are no alterations of consciousness or higher cognitive function. Tinnitus, or a "rushing" sound in the ears, is another frequent complaint. Visual symptoms are present in up to 70 percent of all patients with PTC, and include transient visual obscurations, general blurriness, and intermittent horizontal diplopia.
Avatar m tn About 2 weeks ago, i experienced what I suspect was a heart attack! I dismissed it as indigestion becausre upon vomiting, the pain started subsiding.

1755089 tn?1376057155 Sleep paralysis is associated with sleep that may occur in healthy persons or may be associated with narcolepsy, cataplexy, and hypnagogic hallucinations. The pathophysiology of this condition is closely related to the normal hypotonia that occurs during REM sleep.When considered to be a disease, isolated sleep paralysis is classified as MeSH D020188. Some evidence suggests that it can also, in some cases, be a symptom of migraine. Do talk to ur Dr about this..

They play an important role in helping defend these tissues from disease.

Avatar f tn Coproporphyria manifests with abdominal pain, neuropathies, constipation, and skin changes. Pathophysiology Coproporphyria is an autosomal dominant disease that results from defects in the enzyme coproporphyrinogen oxidase. This enzyme speeds the conversion of coproporphyrinogen to protoporphyrinogen. In coproporphyria, the porphyrin precursors porphobilinogen and amino-levulinic acid (ALA) accumulate, as well as the formed porphyrin coproporphyrin.
Avatar n tn Despite the good overall prognosis, long-term follow-up always is required in patients with GCTs. Pathophysiology Two theories exist to explain the etiology of sex cord–stromal tumors. The first proposes that these neoplasms are derived from the mesenchyme of the developing genital ridge. The second purports that sex cord and stromal cells of the mature ovary are derived from precursors found within the mesonephric and coelomic epithelium.

Avatar m tn • Its pathophysiology is mostly explained by splanchnic and peripheral vasodilatation that lead to a decrease in effective blood volume. • The natural history of ascites results from a progressively more deranged circulatory status; with ascites that initially responds to diuretics, then becoming refractory to diuretics, at which time the patient may develop hyponatraemia and, finally, hepatorenal syndrome. • Most patients respond to diuretics.

Pathophysiology Hepatitis B virus (HBV) is a hepadnavirus.6,7,8,9,10 It is an extremely resistant strain capable of withstanding extreme temperatures and humidity. Hepatitis B virus (HBV) can survive when stored for 15 years at –20°C, for 24 months at –80°C, for 6 months at room temperatures, and for 7 days at 44°C.

Further investigations regarding the role of magnesium in the pathophysiology of RLS and placebo-controlled studies need to be performed. from http://www.ncbi.nlm.nih.
1833449 tn?1333853101 He began having daily tachycardia, severe nausea, weakness and fatigue, bouts of both hypothermia and hypoglycemia (he was growth hormone deficient also), stomach upset and digestive trouble, occasional vomiting.

Avatar n tn I have been severely depressed, exhausted, anxious, had diarhea and vomiting daily, constant aches and pains for years and years. So its kind of a catch 22. I don't know. It helps so much and its been such a long painful road. Reading all this just makes me uneasy about it.

Stomach upset 2. Tired 3.
190559 tn?1280615967 For example, reversible MRI lesions in the cerebral white matter, supposedly reflecting brain edema, have been reported in one case where antithyroid antibodies were detected in the cerebrospinal fluid . Even if the pathophysiology is unknown, the focal and global cerebral involvement have been attributed to autoimmune-mediated cerebral vasculitis, with or without immune complex deposition , and an anti-neuronal antibody-mediated mechanism.
