A derivative of the nitrogenous compound of pyridine, the tobacco alkaloid nicotine, is a potent neuro- and cardiotoxin. In addition to the actual harm of smoking, which causes physical and mental dependence, there can be direct nicotine poisoning of both adults and children.

New possibilities in the treatment of infantile hemangiomas with propranolol

Infantile hemangioma (IG) is a common benign vascular tumor that occurs mainly in preterm and female infants, with localization mainly on the head and neck.

Nevus. Causes. Symptoms. Diagnostics. Treatment

The nevus may be based on autoimmune disorders, that is, the appearance of cytotoxic antibodies in the blood and the effect of cytotoxic lymphocytes. In the depigmentation site, a decrease in the melanin content in melanocytes and the disappearance of the melanocytes themselves from the epidermis are noted.

Nevus Spitz. Causes. Symptoms. Diagnostics. Treatment

Nevus Spitz (syn: spindle cell and / or elithelioid-cell nevus, juvenile melanoma) is an unusual non-moloal melanocyte neoplasm that has a clinical and morphological similarity to the malignant melanoma of the skin.

Nevus removal

A nevus is a benign spot or growth of congenital or acquired origin. Neoplasms can have a different shape and size and vary from flattened spots to large-scale papilloma-shaped elements.

Nevus Ota and Ito. Causes. Symptoms. Diagnostics. Treatment

Nevus Ota is a site of hyperpigmentation of the skin, continuous or with small impregnations, from blue-black to dark brown, with a characteristic localization in the face in the zone of innervation of the trigeminal nerve. Can be two-sided.

Nevus of the conjunctiva. Causes. Symptoms. Diagnostics. Treatment

Nevus of the conjunctiva is a relatively rare, benign, usually unilateral formation. The most frequent localization of the nevus of the conjunctiva is the circumlimate region, the next - in the conjunctival fold and the flesh.

Neutropenia (agranulocytosis, granulocytopenia): causes, symptoms, diagnosis, treatment

Neutropenia (agranulocytosis, granulocytopenia) is a decrease in the number of blood neutrophils (granulocytes). In severe neutropenia, the risk and severity of bacterial and fungal infections increase.

Neutropenia

The criterion of neutropenia in children older than one year and adults is the decrease in the absolute number of neutrophils (stab and segmented) in peripheral blood to 1.5 thousand in 1 μl of blood and lower, in children of the first year of life - up to 1 thousand in 1 μl and lower.

Neurotrophic ulcers

Neurotrophic ulcers occur in patients with lesions of the central or peripheral nervous system. Most often, such ulcers occur in patients with a neuropathic form of the diabetic foot syndrome, CNS trauma and peripheral nerves.

Neurotensinoma

Neurotensinoma - individual neurotensin-producing cells (N-cells) are found in the pancreatic gastrinoma. On the predominantly neurotensin-producing tumors, there are still few reports.

Neuropathy of the upper limbs

The innervation of the hand is carried out by a whole system of peripheral nerves, that is, located outside the brain and spinal cord. Their diseases are not inflammatory genesis (caused by various degenerative and dystrophic processes) called neuropathy.

Neuroparalytic keratitis. Causes. Symptoms. Diagnostics. Treatment

Neuroparalytic keratitis develops after crossing the first branch of the trigeminal nerve, sometimes after injections into the region of the Gasser node or after its extirpation.

Neuromuscular dysfunction of the larynx. Causes. Symptoms. Diagnostics. Treatment

The larynx is the functional center of the upper respiratory tract, finely reacting to minor disturbances of its innervation, endocrine dysfunctions, various kinds of psychogenic factors and occupational and household hazards.

Neuroma of the nose. Causes. Symptoms. Diagnostics. Treatment

The neuroma of the nose is a benign tumor that develops from the nervous tissue; occurs extremely rarely. Neurinomas as such are divided into gliomas - congenital tumors developing from neuroglia and related to benign tumors, and neuroblastomas that can occur at any age and are characterized by a malignant course.

Neurologic disorders of the pharynx. Causes. Symptoms. Diagnostics. Treatment

At the basis of adequate functioning of the pharynx lie the most complicated mutually consistent nervous processes, the slightest violation of which leads to disorganization of food and air-flow functions at this level.

Neuroleptic Syndrome

NMS most often develops soon after initiation of treatment with neuroleptics, or after increasing the dosage of medications taken.

Neurogenic muscle contractures

The term "contracture" is applicable to all cases of persistent, fixed muscle shortening. At the same time EMG looks "silent" in contrast to the transient forms of muscle contraction (cramp, tetanus, tetany) accompanied by high-voltage high-frequency discharges on the EMG.

Neurogenic hypoglycemia. The reasons. Symptoms Diagnostics. Treatment

Neuroglycopic symptoms occurring due to a deficiency in the supply of glucose to the brain, and symptoms caused by compensatory stimulation of the sympathoadrenal system should be separated. The first are manifested by headache, inability to concentrate, confusion, inadequate behavior.

Neurogenic hyperthermia (fever)

An increase in body temperature with adequate thermoregulation is called a fever. Hyperthermia develops with excessive metabolic heat production, excessively high ambient temperature or with defective heat transfer mechanisms
