Post-traumatic stress disorder is accompanied by affective disorders: a low mood (subdepressive register), subjectively perceived as a constant dissatisfaction with oneself (and / or the surrounding situation), and with barely suppressed irritability.

According to the literature data, post-gastro-resection disorders develop in 35-40% of patients who underwent gastric resection. The most common classification of these disorders is the Alexander-WiUams classification (1990), according to which the following three main groups are distinguished: Impaired gastric emptying as a result of resection of the pyloric section and, consequently, the transport of gastric contents and food chyme bypassing the duodenum.

Postgastorezektsionny syndrome - a collective concept, which includes a number of pathological conditions of the body, developing after surgery resection of the stomach and vagotomy.
Portosystemic encephalopathy is a reversible psychoneurological syndrome that develops in patients with portosystemic shunting. Symptoms of portosystemic encephalopathy are mainly psychoneurological (for example, confusion, "clapping" tremor, coma).
Thrombosis of the portal vein leads to portal hypertension and subsequently to gastrointestinal bleeding. Diagnosis is based on ultrasound. The treatment is mainly directed to the control and prevention of gastrointestinal bleeding (usually endoscopy or intravenous octreotide), sometimes vascular bypass or b-blockers; with acute thrombosis, thrombolysis is possible.

Portal hypertension - increased pressure in the portal portal vein, caused by blood flow disorders of various origins and localization - in portal vessels, hepatic veins and inferior vena cava.

The existence of porphyrin substance and the violation of its metabolism were discovered more than 100 years ago. N. Guntcr (1901) called diseases that occur with a disruption of porphyrin metabolism, "hemoporphyria", and J. Waldenstrom (1937) by the term "porphyria".
Porokeratosis unites a group of diseases characterized by a violation of keratinization.
The main causes of blindness and poor vision and their frequency are different in different regions of the world, which is due to a number of factors (socioeconomic, demographic, geoclimatic, etc.), as well as the level of medicine and in particular the state of the ophthalmic pediatric service. The prevalence of child blindness in the world is about 1.3 million, visually impaired people - 5.2 million people.

Polytrauma in the English-language literature - multiple trauma, polytrauma. Combined trauma is a collective concept that includes the following types of damage: multiple - damage to more than two internal organs in one cavity or more than two anatomical and functional structures (segments) of the musculoskeletal system (for example, damage to the liver and intestine, fracture of the femur and forearm bones ).

In most cases, polyps are asymptomatic and are a random finding in endoscopy performed for any other disease or for the purpose of preventive examination of the large intestine.

Polyps make up the most significant portion of benign laryngeal tumors. They most often occur in males in adulthood. The reasons for their occurrence are the same factors as for singing knots.

Why there are polyps of the large intestine, as well as tumors in general, is still unknown. The diagnosis of colon polyps is done with the help of a colonoscopy (with tumor biopsy or polypoid formation) and usually performed with the appearance of some symptoms or complications, as well as with the "expanded" clinical examination of certain populations with an increased risk of carcinomatosis.
Polyps of the cervical canal are benign growths of the cervix and mucous membrane of the cervical canal. Cervical polyps grow in the cervical canal.

Most often, these formations have a globular configuration, and are a benign growth of the mucous tissues of the organ.

Polypous allergic rhinitis is a manifestation of a general body allergy and, as a rule, enters into the concept of polypous rhinosinusitis.
The term "cervical polyp" implies focal proliferation of endocervix in which tree-like outgrowths of connective tissue covered with cylindrical epithelium protrude into the lumen of the cervical canal or beyond.
Polyp of the intestine is any proliferation of tissue from the intestinal wall and protrudes into its lumen. Most often, polyps are asymptomatic, with the exception of minor bleeding, which is usually hidden.
Polyneuropathies are a heterogeneous group of diseases, characterized by systemic damage to the peripheral nerves (Greek poly - many, peiro - nerve, pathos - disease).
