List Diseases – V
This section includes a group of behavioral disorders characterized by a persistent type of dissocial, aggressive or challenging behavior, reaching a marked violation of age-appropriate social norms.
Today, poisoning with various substances happens quite often. At the same time, poisonings are more often observed, which do not occur as a result of exposure to potent toxins and poisons, but as a result of the ingestion of household substances, which at first glance are very harmless.
Vinegar, like any other substance, can bring both benefit and harm to man. The use of vinegar is undeniable: it is widely used in everyday life, in cooking. Preparation of dishes, preservation can not do without vinegar.
The empyema of the pleura in most cases is a complication of inflammatory and purulent-destructive lung diseases, injuries and surgical interventions on the thoracic organs and is the most complicated section in thoracic surgery.
Vestibular neuronitis - an acute (viral) lesion of the vestibular ganglion, vestibular nuclei and other retrolabirint structures, isolated into an independent nosological form in 1949 by the American otolaryngologist by C.Hallpike.
The disease got its name due to the British doctor Vesta, who first described all his symptoms in 1841, watching his sick son.
Vesiculopustulosis is a purulent inflammation of the mouths of the merocrine sweat glands. The disease of vesiculopustulosis begins at the mouth of the sweat glands. The main symptoms of vesiculopustule are the formation of pustules in the mouth of the sweat glands of the size of a pinhead, surrounded by a corolla of hyperemia with a dense cover.
Vesicular stomatitis is an acute infectious disease, which, often, affects representatives of the animal world (mainly cattle).
Verrushiform epidermodysplasia of Lewandowski-Lutz (blue verrucosis generalisata) is a rare disease, in some cases familial. Assumed autosomal recessive or X-linked inheritance.
If a person is often tormented by dizziness, he experiences instability during walking, there is reason to suspect that he has a violation of blood flow in the vertebral arteries.
Vertebro-basilar insufficiency is a process of impaired brain function associated with decreased blood supply.
Vestibular dysfunction of vascular genesis (vertebral-basilar insufficiency, discirculatory encephalopathy) is a violation of the vestibular function associated with a circulatory disorder in the central or peripheral parts of the vestibular analyzer.
In the emergence of the disease an important role is assigned to the 3rd and 5th types of human papillomavirus (HPV-3 and HPV-5). It is possible to transform verandiiform epidermodysplasia of Lewandowski-Lutz into squamous cell carcinoma or Bowen's disease. There is information about the important role of hereditary factors.
Although the warts are benign neoplasms and mostly do not pose a threat to life, but they spoil the appearance when placed in prominent places or cause functional inconvenience, sometimes hurt, such as plantar when walking.
Among the benign pigmented lesions on the skin - nevi (from the Latin naevus - mole) - a warty nevus protruding above the skin surface is distinguished, which, as the name implies, looks like a wart.
Ventricular tachycardia occupies a special place in arrhythmology, as it has a wide variability in clinical manifestations and, in some cases, a high probability of an unfavorable prognosis. Many ventricular tachycardias are associated with a high risk of ventricular fibrillation and, consequently, sudden cardiac death. Under ventricular tachycardias, a ventricular rhythm with a heart rate of 120-250 per minute is taken, consisting of three or more consecutive ventricular complexes.
Ventricular tachycardia of the "pirouette" type is a special form of polymorphic ventricular tachycardia in patients with an elongated interval. It is characterized by frequent, irregular complexes of QRS, which seem to "dance" around the contour on the electrocardiogram.
Ventricular tachycardia consists of three or more consecutive ventricular pulses with a frequency of 120 per minute. The symptoms of ventricular tachycardia depend on the duration and vary from a complete lack of sensation and palpitations to hemodynamic collapse and death.
Ventricular fibrillation is uncoordinated excitation in the ventricles, which does not lead to a useful reduction. Ventricular fibrillation leads to immediate loss of consciousness and death within a few minutes. Treatment is performed by performing cardiopulmonary support, including immediate defibrillation.
Ventricular extrasystole (VES) - single ventricular impulses resulting from re-entry involving ventricles or abnormal automatism of ventricular cells. Ventricular extrasystole is often found in healthy people and in patients with cardiac disease.
