Congenital heart defects (valvular stenosis of the pulmonary artery, ventricular septal defect), cryptorchidism in boys in 60% of cases, combined deformation of the chest are diagnosed from birth.

Nonspecific ulcers of the small intestine

Non-specific ulcers of the small intestine are extremely rare. In the literature, one can find only isolated descriptions of this disease. These are non-specific ulcers, unlike ulcerations of an established nature, which can be tuberculous, syphilitic, and cancerous.

Nonspecific ulcerative colitis.

Non-specific ulcerative colitis is a disease of unknown etiology, characterized by the development of a necrotizing inflammatory process of the mucous membrane of the large intestine with the formation of ulcers, hemorrhages and pus.

Nonspecific interstitial pneumonia

Non-specific interstitial pneumonia is a histological variant of IBLAR that does not correspond to its other more specific histological forms.

Nonspecific aortoarteritis (Takayasu's disease)

Non-specific aortoarteritis (aortic arch syndrome, Takayasu disease, pulseless disease) is a destructive-productive segmental aortitis and subaortic panarteritis of arteries rich in elastic fibers with possible damage to their coronary and pulmonary branches.

Nonparoxysmal tachycardias. Causes. Symptoms. Diagnosis. Treatment

Tachycardias are classified as chronic if they have been present in the patient for more than 3 months in a row (in chronic sinus tachycardia) and more than 1 month in tachycardias based on an abnormal electrophysiological mechanism.

Nonketone hyperosmolar syndrome.

Nonketone hyperosmolar syndrome is a metabolic complication of diabetes mellitus, characterized by hyperglycemia, severe dehydration, plasma hyperosmolarity, and impaired consciousness. It is most often observed in type 2 diabetes mellitus, often under physiological stress.

Noninfectious vesiculopustular dermatoses. Causes. Symptoms. Diagnosis. Treatment

Non-infectious vesiculopustular dermatoses, characterized by the presence of sterile pustules in the skin, include a large group of diseases, including both generalized and limited forms.

A doctor who observes a patient with high blood pressure always faces the question: what form of arterial hypertension does the patient have - essential or secondary, since this affects the treatment tactics and prognosis of the disease.

Non-stenotic atherosclerosis

Elevated cholesterol is the underlying cause of non-stenotic atherosclerosis. The buildup of lipids and calcium on the inner wall of the arteries provokes a persistent disorder of blood flow.

Non-pulmonary acute thyroiditis

Non-purulent acute thyroiditis occurs as an aseptic inflammation due to trauma and hemorrhage in the gland or after radiation therapy.

Non-infectious endocarditis: causes, symptoms, diagnosis, treatment

Non-infective endocarditis (non-bacterial thromboendocarditis) is a disease accompanied by the formation of a sterile platelet and fibrin thrombus on the heart valves and adjacent endocardium in response to trauma, circulating immune complexes, vasculitis, or increased blood clotting.
