Hyphema (hemorrhage in the anterior chamber of the eye) is an eye injury that requires the immediate involvement of an ophthalmologist.
Hyperventilation syndrome (Da Costa syndrome, stress syndrome, nervous respiratory syndrome, psychophysiological respiratory reactions, irritable heart syndrome, etc.) in recent years has attracted the attention of many researchers due to its frequency and the large role it plays in the formation of numerous clinical manifestations.
In the membranous-cartilaginous part of the auditory tube there are clusters of lymphadenic tissue, first described by the German anatomist Gerlach. This tissue is more developed in the region of the isthmus of the auditory tube and is especially abundant in the area of the socket of the nasopharyngeal opening, where it forms the tubal amygdala.
Hypertrophy of the tonsils (hypertrophic tonsillitis), like hypertrophy of the pharyngeal tonsil, most often occurs in childhood as a manifestation of a common lymphatic constitution. In most cases, there are no inflammatory changes in hypertrophied tonsils.
Hypertrophy of the seminal tubercle is a congenital malformation of the development, for which hyperplasia of all structural elements of the seed tubercle is characteristic.
Hypertrophy of the lingual tonsil is a frequent anomaly of the development of this organ, which is often accompanied by hypertrophy and other solitary lymphadenoid formations of the pharynx.
Probably, many faced personally or heard from friends about a diagnosed condition such as hypertrophy of the left atrium. What is it? How dangerous is everything, because it is known that from the lungs, the blood enriched with oxygen comes immediately to the left atrium?
Hypertrophic cardiomyopathy is a congenital or acquired disease characterized by severe ventricular hypertrophy with diastolic dysfunction, but without increased afterload (unlike, for example, valvular aortic stenosis, coarctation of the aorta, systemic arterial hypertension).
Hypertrophic cardiomyopathy is a myocardial disease characterized by focal or diffuse myocardial hypertrophy of the left and / or right ventricle, more often asymmetric, involving the hypertrophic process of the interventricular septum, normal or reduced volume of the left ventricle, accompanied by normal or increased contractility of the myocardium with a significant decrease in diastolic function.
Hypertrichosis is excessive local or widespread hair growth in those areas of the skin where hair should not be. In the special literature one can find synonyms Hypertrichosis (hypertrichosis) - polytrichia, virile syndrome, although many doctors attribute these diseases to different types of one category.
Hypertonic crisis - severe arterial hypertension with signs of damage to target organs (primarily the brain, cardiovascular system and kidneys). The diagnosis is determined by measuring blood pressure, ECG, urinalysis and the study of urea and creatinine in the blood.
Hypertensive syndrome in surgery is viewed from several positions. Arterial hypertension is important insofar as it can cause a number of vascular complications, both during the operation and after it: hemorrhages, ischemia, crises, etc.
The primary reaction of retinal arterioles in response to systemic hypertension is narrowing (vasoconstriction). However, the degree of narrowing depends on the replacement volume of fibrous tissue (involutional sclerosis).
Hypertensive crisis - a sudden increase in blood pressure, causing significant deterioration in health and requiring emergency care.
With hypertension of any genesis, changes in the vessels of the fundus are noted. The degree of severity of these changes depends on the height of blood pressure and the duration of hypertension.
Hypertension in the elderly is most often observed in the age group over 60; it develops in the early or later periods of life. Symptomatic arterial hypertension caused by atherosclerosis (sclerotic, predominantly systolic hypertension), kidney disease, or other causes may also occur.
Hypertension is a very common disease. It develops as a result of narrowing of small vessels. Increased pressure is often a symptom of other diseases, or be primary, which is an independent nosological unit.
Hypersensitivity to drugs is an immune-mediated response.
Now there is a lot of data on the effect of prolactin on the human reproductive system. It is established that it actively affects the hormonal and spermatogenic functions of the testicles.
Hypersplenism is a syndrome of cytopenia caused by splenomegaly. Hypersplenism is a secondary process that can be caused by splenomegaly caused by a variety of causes. Treatment is aimed at the underlying disease. However, if hypersplenism is the single most serious manifestation of the disease (eg, Gaucher's disease), ablation of the spleen can be indicated by splenectomy or radiotherapy.
