Gurevich Symptom

Gurevich symptom is a clinical sign that was described by the Soviet surgeon Nikolai Ivanovich Gurevich in 1881. This symptom occurs when the spleen is damaged and can be used to diagnose this condition.

Gurevich symptom is determined by the presence of pain in the left hypochondrium, which intensifies with pressure on the spleen area. This is because when damaged, the spleen becomes more sensitive to pressure and this causes pain.

This symptom was named after Nikolai Ivanovich Gurevich, the Soviet surgeon who first described it in 1901. Gurevich was one of the first to study abdominal and liver surgery, and his work was of great importance for the development of this field of medicine.

Gurevich's symptom is an important diagnostic sign for abdominal injuries, especially when the spleen is damaged. It can be used to determine the severity of the injury and select the correct treatment strategy.

In conclusion, Gurevich's sign is an important clinical sign that is used to diagnose splenic injuries. This symptom can help doctors determine the severity of the injury and choose the right treatment strategy.

**Gurevich symptom**

Gurevich's symptom, ophthalmoscope, is named after the outstanding ophthalmologist N.I. Gurevich, a Soviet surgeon who developed a type of spinal anesthesia using the epidural method. A symptom is proposed for identifying damage to the retina of the fundus, a symptom of retinal ischemia, determining its visual purple, as well as the boundaries of the visual field zone affected by retinal ganglion cells-receptors. Typically manifested by the presence or absence of a halo around the optic disc.

_**Description of symptom**_ Gurevich or the perimetry method using a mirror angle is the simplest method for determining visual fields. A mirror is held at a distance from the patient’s eyes, with a reflected image of a white flashlight on both sides, similar to a “perioscopic shutter.” A piece of black paper about 2 cm wide is inserted between the mirrors. The patient looks at the pointer, with peristaltic movements under the control of the mirror surfaces up and down, he turns the body (the head and body segments are rotated by 30–40 °), leading to rotation of the reflective surfaces of the mirrors, moving the limiter focus that is in focus of the perimeter pointer. The doctor perceives the movement of the flashlight, its approach and distance, monitors the movement of the border of its black-and-white area and the time of this movement. IN
