Histiocytosis X (syn: histiocytic medullary reticulosis, malignant reticulogistiocytosis). Histiocytosis from the cells of Langerhans make up a group that includes the Letterer-Sieve disease, the Hend-Schuller-Crischen disease, the eosinophilic granuloma
Fetal hypoxia, or oxygen starvation, is a pathological condition that occurs in the fetus and the newborn as a result of oxygen deficiency.
Hypoxia is an oxygen deficiency, a condition that occurs when the body's oxygen supply is insufficient or when it is disrupted in the process of biological oxidation, accompanies many pathological conditions, being a component of their pathogenesis and clinically manifested by a hypoxic syndrome based on hypoxemia.
Hypovolemia (from French volume - an unambiguous notion defining tension and volume) is a decrease in the vascular tone that occurs with massive plasma and blood loss or a decrease in vascular tone due to disorders of neural-reflex regulation.
Hypotrophy is an alimentary-dependent condition caused by a predominant protein and / or energy starvation of sufficient duration and / or intensity.
Hypothyroidism is a clinical syndrome caused by a prolonged, persistent deficiency of thyroid hormones in the body or a decrease in their biological effect at the tissue level.
Hypothyroidism is a clinical syndrome caused by a decreased production of thyroid hormones or a lack of sensitivity to them in tissues. Allocate congenital and acquired hypothyroidism; the level of disturbance of regulatory mechanisms distinguishes primary (pathology of the thyroid gland itself), secondary (hypophysial disorders) and tertiary (hypothalamic disorders).
Insufficient level of thyroid hormones in organs and tissues leads to the development of hypothyroidism - a disease first described by V. Gull in 1873. The term "myxedema", owned by VM Ordu (1878), means mucous edema of the skin and subcutaneous tissue.
Hypospadias are a congenital anomaly of the penis, which manifests by splitting the posterior wall of the urethra from the glans penis to the perineum.
Hypothermia - decrease in internal body temperature below 35 ° С. Symptoms progress from trembling and drowsiness to stunning, coma and death.
Hypothalamic prepubertal hypogonadism can be observed in the absence of organic changes in the hypothalamic region. In this case, congenital, possibly hereditary, pathology is assumed. It is also observed in structural lesions of the hypothalamus and the pituitary foot in cases of craniopharyngiomas, internal hydrocephalus, neoplastic processes of various types
Hypotension of the eye occurs as a consequence of other diseases of the eyes or the whole body. Intraocular pressure may decrease to 7-8 mm Hg. Art. And lower from the true figures.
Subconjunctival, or intraocular hemorrhage, otherwise called hyposhagmus, occurs when a small blood vessel is damaged, as a result of which a small amount of blood is poured under the conjunctiva.
Hypoproliferative anemia is the result of a deficiency of erythropoietin (EPO) or a decrease in its response; they are, as a rule, normochromic and normocytic
Hypoplasia of the optic nerve, one-sided or two-sided, is characterized by a reduced amount of nerve fibers. Hypoplasia of the optic nerve can be an isolated anomaly, it can be combined with other developmental defects of the eye or a heterogeneous group of diseases, most often affecting the midline structures of the brain.
Hypoplasia of the kidney is an anomaly of development, characterized by a decrease in the size of the kidney. This defect occurs with a frequency of 0.9% among all kidney anomalies.
Hypoplasia of the condylar process - deformation of the face, caused by a decrease in the height of the jaw branch.
The pathology of the structure or mineral composition of the dental tissue (partial or complete absence of it), which develops due to a malfunction that arose even in the period of their formation, is a hypoplasia of the teeth.
Of particular interest is the fact that a person has an organ that may or may not be present, and nothing will change from this. This applies in the first place, frontal sinuses.
Previously, one of the main causes of hypopituitarism was ischemic necrosis of the pituitary gland (necrosis of the pituitary gland, which developed as a result of massive postpartum hemorrhage and vascular collapse - Shikhen syndrome, pituitary necrosis due to postpartum sepsis - Simmonds syndrome, recently often used the term "Simmonds syndrome - Shihena ").
