the cause, set of causes, or manner of causation of a disease or condition:
"a disease of unknown etiology"
Etiologic means causative. For instance, Treponema pallidum is the etiologic agent for syphilis.
Neoplastic etiology is the study of the cause for the growth of the abnormal proliferation of malignant cells.
From causes such as dehydration, cardiac arrhythmias, neurologic etiologies, and many more, dizzy spells require a medical examination (and, potentially, one or more tests, as well).
It depends upon the cause. There are both cardiovascular as well as neurologic etiologies (and even psychologic/psychiatric ones too). But first of all, make sure to drink plenty of fluids. Dehydration is one major cause of lightheadedness.
The most likely explanation is that he has used alcohol and/or some type of sedative medication - which is impairing his speech. However, other causes include stroke (cerebrovascular accident), mini-stroke (transient ischemic attack) or partial seizure, among other potential etiologies.
A pleural effusion is exesive collection of fluid in the pleural This can be the result of excess fluid production or decreased absorption. It is the most common manifestation of pleural disease, with etiologies ranging from cardiopulmonary disorders to symptomatic inflammatory or malignant diseases. RA is an inflamatory disease that effects connective tissue and produces fluid . unfortunately in about 2 to 5% RA cases it can manifest itself in the Lungs.
Please see a doctor Immidiately. Any kind of lump in the body should be dealt with seriously and shown to the doctor at the earliest. I agree with the above - most likely the lesion is an infection of the lymph node (aka - adenitis). There are a few other etiologies for such a clinical presentation, too.
asthma is currently recognized as a noninfectious disease. Asthma is considered a "reactive airway disease," meaning basically that the airway is reacting to some type of irritant. Asthma attacks can be triggered by many things such as allergens, cold air, or exercise. These irritants cause inflammation in the airway walls and mucus production, which can narrow the airway and make breathing difficult. Interesting question however, as some newer data has actually supported infectious etiologies such as chlamydia as a possible underlying cause of asthma... but not proven yet.
Autoimmune disease is the scientific demonstration of abnormalities in invulnerable directive that pilot to tissue smash up by self-reactive lymphocytes and autoantibody, resultant in incapacitating symptoms and bereavement when very important organs are influenced. The cause of most autoimmune ailments continues doubtful, even though ecological factors are strappingly indicated in the course of studies in animal models. Universal autoimmune diseases include general lupus erythematosus, systemic sclerosis and rheumatoid arthritis come into sight to have multifaceted etiologies with gene-environment communications
HIV is a progressive infection because the onset of symptoms and other pathological consequences is increasing in severity which eventually can lead to death. As you know, HIV infects the immune cells in the body rendering the body defenseless or immunocompromised. Actually what makes HIV infection more severe is the onset of other infections from other etiologies which a normal non-immunocompromised do not get.
Papilledema is an optic disc swelling that is secondary to elevated intracranial pressure.[1, 2] In contrast to other causes of optic disc swelling, vision usually is well preserved with acute papilledema. Papilledema almost always presents as a bilateral phenomenon and may develop over hours to weeks. The term, as a matter of definition, is incorrect to be used to describe optic disc swelling with underlying optic nerve infectious, infiltrative, or inflammatory etiologies; but, it is correctly used if the underlying cause of elevated intracranial pressure is infectious, infiltrative, or inflammatory.
