One of the rare and most difficult to diagnose among liver diseases is Budd-Chiari disease - primary obliterating endophlebitis of the hepatic vein, followed by thrombosis and portal hypertension.

The present work is an attempt at a theoretical understanding of the essence and some features of a rather rare and clinically severe disease - colon polyposis.

The importance of iron deficiency in the development of early anemia of prematurity is controversial. Hematologically, some researchers characterize it as hypochromic, others as normo- or even slightly hyperchromic.

In outpatient practice, doctors often resort to the study of gastric juice obtained by probing. Doctors-laboratory assistants who carry out these manipulations know very well that when a gastric tube is inserted, especially in young children, we get inadequate, more often increased reactions, cause unpleasant or painful sensations.

We analyzed the causes of death of 48 children from acute appendicitis in hospitals in the region for the period from 1961 to 1970.Based on our belief that death in this disease is always associated with diagnostic, tactical and other errors, we also tried to identify the most frequently encountered among them in order to develop measures to prevent them.

On a relatively small number of observations by foreign authors described "appendicular" (mesenteric lymphadenitis), intestinal, septic-typhoid [5] forms of pseudotuberculosis, as well as forms in the form of erythema nodosum, conjunctivitis, splenomegaly, lymphadenopathy, septicemia [6].

Access to the organs of the subphrenic space is a difficult surgical problem. The approaches associated with penetration through the pleural cavity or with the dissection of the costal-cartilaginous obstruction and the sternum are traumatic. They are associated with additional trauma to the patient.

For the first time a transillumination study of the mammary glands was proposed and carried out by Kutler (1929). Later, N. N. Kukin (1949) was engaged in questions of transillumination of mammary glands. The authors note the effectiveness, great simplicity of this method and harmlessness to the patient.

Operations for fistulas of the sacrococcygeal region on the basis of the epithelial coccygeal passage at first glance do not present any particular difficulties. They consist in excision of the primary opening of the course itself and all secondary purulent fistulas under the control of fistulography and intraoperative marking of purulent passages with methylene blue.

We have sufficient clinical observations that convincingly show that doses of penicillin taken in hospitals in our country in general purulent surgical processes often do not provide the expected therapeutic effect.

The analgesic effect of a weak electric current has been known for a long time. According to modern biophysical concepts, it is associated with depolarization of pain receptor membranes, with a decrease in their sensitivity [7]. Depolarization of membranes occurs mainly during the passage of an electric current or exposure to voltage. Consequently, the effect of various kinds of short-term electro-procedures is most likely a manifestation of the aftereffect of depolarization.

Hearing damage as a result of side effects of medicinal substances has been known for a long time, but they remained sporadic for a long time and did not cause much alarm for this reason. With the introduction of new drugs into clinical practice, especially antibiotics, cases of toxic damage to the organ of hearing began to increase.

Blood transfusion, provided that the appropriate instructions are followed, is usually not accompanied by pathological reactions of the body. However, it should be remembered that even with all the tests, complications are occasionally possible (according to LIPK-1 per 600,000 blood transfusions). In some cases, such complications are explained by the presence of isohemoagglutination variants in the blood of the donor or patient.
