Diseases of children (pediatrics)

Pheochromocytoma, catecholamine crisis: causes, symptoms, diagnosis, treatment

The catecholamine crisis is a life-threatening emergency. It develops mainly with pheochromocytoma (chromaffinoma), a hormone-producing tumor of chromaffin tissue.

Acute adrenal insufficiency

Acute adrenal insufficiency is a syndrome that develops as a result of a sharp decrease or complete cessation of hormone production by the adrenal cortex.

Acute allergic diseases of the skin include urticaria, edema Quincke, toxicermia, multiforme, exudative erythema, Stevens-Johnson syndrome, Lyell's syndrome. These diseases are characterized by damage to the skin, mucous membranes, internal organs with the possible development of life-threatening conditions that require urgent intensive therapy.

Anaphylactic shock in children

Anaphylactic shock develops sharply after the patient's contact with an intolerable allergen and is a life-threatening condition that is accompanied by a violation of hemodynamics, leading to circulatory insufficiency and hypoxia in all vital organs.

Quincke's edema in children

Quincke edema is a morphological variant of urticaria, it is a clearly limited edema of the skin and subcutaneous tissue. B1 5-20% observed the edema of Quincke without urticaria.

Allergic urticaria

Rashes in acute urticaria is a monomorphic rash with erythema border. Sometimes the rash is similar to scarlet fever and measles. The disease begins acutely and is accompanied by severe itching of the skin. On sites of an itch appear hyperemic sites of an eruption. As the edema of the papillary layer of the dermis increases, the papular elements pale.

Acute rhinoconjunctivitis

The pathogenetic basis is formed by IgE-mediated allergic reactions. Rhinoconjunctivitis is a classic example of atopic diseases characterized by the presence of hyperproduction of IgE, a high level of specific IgE and IgC4 antibodies, an imbalance of immunoregulatory cells.

Acute bronchial obstruction

Obstructive disorders in the lower respiratory tract arise as a result of obstruction of the movement of air in the trachea at the level of the keel of the trachea, large and medium bronchi.

Acute respiratory failure

Acute respiratory failure is a condition characterized by a violation of the normal gas composition of the arterial blood: the delivery of a sufficient amount of oxygen to the arterial blood and the removal of an appropriate amount of carbon dioxide from the venous blood into the alveoli. Disruption of pulmonary gas exchange leads to a decrease in pAO2 (hypoxemia) and an increase in pCO2 (hypercapnia).

Stenosing laryngotracheitis (croup syndrome)

Stenosing laryngotracheitis, or croup syndrome, is an inflammatory disease of the upper respiratory tract, leading to laryngeal stenosis.
