[Evaluation of wound healing process].

Mathematical modelling of wound healing process gave use to new nontraditional methods for treatment of festered wounds of various origin: volume-loaded activated water with pH from 2.4 to 11.3, being used for dressings and prepared in electrohydrolyzer with graphite anode (which possessed electric potential +1.

[Difficulties and errors in diagnosis and treatment of closed trauma to the abdominal organs].

A critical analysis of the difficulties and errors in the diagnosis and treatment of closed injuries to the abdominal organs during a period of 30 years is given. In the first period (1960-72) diagnostic laparotomy was applied widely in all questionable cases, which in 32 out of 252 (12.7%) patients failed to reveal injuries to the viscera, but aggravated the general condition and promoted a fatal outcome in some patients.

[Ways to improve ambulatory care for patients with surgical infection].

A deep analysis of purulent surgical diseases and purulent complications in 5,780 out-patients was conducted by means of a specially worked out punch card. Four groups were identified posttraumatic purulent complications--accidental wounds, abscesses, phlegmons, panaris, regional lymphadenitis, osteomyelitis, etc.--3,274 (56.

[Microbial contamination of wounds and prevention of suppurative complications].

A specially elaborated punch card was used to study 1,784 case records of patients with pyogenic complications of wounds of various origin: pyogenic complications after cavitary operations, purulent surgical diseases; pyogenic complications of injuries, injections, and trophic ulcers. It was established that each type of wound is characterized by its own microflora. A follow-up showed that surgical intervention in combination with various antiseptics differ in their effect on microbial dissemination.

[The use of hemoperfusion through a suspension of cryopreserved hepatocytes in acute liver failure].

The present work deals with results of intensive therapy and temporary organ substitution by using hemoperfusion through a suspension of living donor hepatocytes in 71 patients with acute hepatic insufficiency. Hemoperfusion was performed through a suspension of fresh living hepatocytes or through a suspension of cryo-conserved (during 60 days) living hepatocytes. Lethality was 37-42%.

[Acute submandibular lymphadenitis : its treatment and prognosis].

The authors analyze the results of therapy of 1288 patients with acute submaxillary lymphadenitis, discuss the causes of the development of this condition, and draw attention to the necessity of improving dental care of the population. Comparison of various treatment modalities has demonstrated a high efficacy of radical operation combined with physio- and hydroaeroionotherapy. The authors present their prediction for the duration of temporary invalidity periods because of this condition for the period of up to the year 2000 and the economic assessment of this prediction.

[Causes of suppurative complications after appendectomy].

The causes of purulent complications in 9,518 patients after appendectomy were studied. The total percentage of purulent complications was 8.0 (6.

[Errors, risks and complications in the diagnosis and treatment of acute suppurative pelviorectal paraproctitis].

Under analysis were the course of acute pelviorectal paraproctitis in 39 patients, diagnostic errors and complications and resulting problems in cases of late medical consultation and tardy operative intervention. The correct diagnosis was made but in 19 patients in operation for purulent leaks. In 20 patients the disease was not diagnosed and treatment was limited by opening the purulent abscesses.

[Diagnostic problems and complications of closed injuries of the duodenum].

During the period from 1963 to 1983 there were 16 patients with closed injuries of the duodenum. Diagnostic errors were made in operations on 3 patients. Eight patients recovered, eight patients died (retroperitoneal ruptures in 6 patients, intraperitoneal ruptures in 2 patients).
