Arrhythmogenic cardiomyopathy of the right ventricle in children. Causes. Symptoms. Diagnosis. Treatment.

Right ventricular arrhythmogenic cardiomyopathy is a rare disease of unclear etiology, characterized by a progressive replacement of the right ventricle myocytes with fatty or fibrous fat tissue leading to atrophy and thinning of the ventricular wall, its dilatation accompanied by ventricular rhythm disturbances of varying severity, including ventricular fibrillation.

Arrhythmias in children and their treatment

Arrhythmias in children - heart rhythm disorders, which are often the cause of cardiovascular failure. Treatment of arrhythmia in children is different and depends on the visible rhythm disturbance.

Arrhythmia

Arrhythmia is not a separate, independent disease, it is a group of symptoms united by one concept - a violation of the normal heart rhythm.

Argyrosis

With the accumulation of silver in the tissues of the body (in ancient Greek - argyros, in Latin - argentum), a disease such as argyrosis or argyria can occur.

Arachnoid cyst

Arachnoid cyst is a fluid-filled cavity, the walls of which are lined with cells of the arachnoid shell. Such formations are located between the surface of the brain and the arachnoid shell.

Arachnoentomoses of humans and animals

Arachnodactyly

One of the rare hereditary connective tissue pathologies is arachnodactyly - deformity of the fingers, accompanied by lengthening of the tubular bones, skeletal curvatures, disorders of the cardiovascular system and visual organs.

APUD tumors - systems

The APUD system is a diffuse endocrine system that unites cells found in virtually all organs and synthesizes biogenic amines and numerous peptide hormones. It is an actively functioning system that supports homeostasis in the body.

Apraxia

Apraxia is the inability to perform targeted motor acts that are customary for the patient, despite the absence of primary motor defects and the desire to produce this action, which develops as a result of brain damage. The diagnosis is made on the basis of clinical symptoms, data of neuropsychological and visualization (CT, MRI) studies.

Appendicular infiltration (abscess). The reasons. Symptoms Diagnostics. Treatment

Differential diagnostics of the appendicular infiltrate and purulent tubo-ovarian formation of the right-sided localization presents considerable difficulties due to the longer process.

Appendicular abscess

Acute appendicitis is a very common surgical pathology. Such a disease requires urgent surgical intervention, otherwise serious and life-threatening complications may develop.

Appendicitis: symptoms

Appendicitis is formed at any age, against a background of complete health, suddenly. Appendicitis symptoms are typical, which are manifested by the appearance of pain in the right iliac region or in epigastrium (Kocher's symptom), or near-the-buccal region (Kymmel symptom).

Appendicitis: causes, symptoms, diagnosis, treatment

Appendicitis phlegmonous

Phlegmonous appendicitis is an acute form of inflammation of the appendix, characterized by the deposition of fibrin on its surface, a large concentration of pus and a clearly marked edema.

APP

Pancreatic peptide (PP) is secreted by F-cells of the pancreas. In general, the peptide reduces the contractile function of the gallbladder, increases the tone of the common bile duct and inhibits the endocrine function of the pancreas.

Apostematous pyelonephritis. Causes. Symptoms. Diagnostics. Treatment

Apostematous pyelonephritis is a purulent-inflammatory disease that is accompanied by the formation of a large number of small pustules in the kidney tissue. What is the prognosis of apostematous nephritis?

Apoplexy of the ovary. Causes. Symptoms. Diagnostics. Treatment

Apoplexy is the rupture of the ovary, which often occurs in the middle or in the second phase of the menstrual cycle. The leading symptom of ovarian apoplexy is acute, intensifying pain in the lower abdomen and increasing symptoms of intra-abdominal bleeding with undisturbed menstrual function.

Apnea of prematurity

Apnea of prematurity is defined as respiratory pauses of more than 20 s, or interruption of air flow and respiratory pauses of less than 20 s combined with bradycardia (less than 80 beats / min), central cyanosis or O2 saturation of less than 85% in children born less than 37 weeks gestation, and in the absence of causes that cause apnea. The reasons may be immaturity of the central nervous system (CNS) or airway obstruction.

Aplastic anemia (hypoplastic anemia): causes, symptoms, diagnosis, treatment

Aplastic anemia (hypoplastic anemia) - normochromic-normocytic anemia, is the result of depletion of the reserve of hematopoiesis precursors, which leads to bone marrow hypoplasia, a decrease in the number of red blood cells, white blood cells and platelets
