The disease course in 68 patients with appendicular infiltrate (AI) and periappendicular abscess (PAA) is analysed. There were 42 men and 26 women at the age of 15-76 years. AI was detected in 12 patients, PAA-in 56 patients. In 39 patients diagnosis was made on the basis of clinical examination, laboratory tests and X-ray examination. Ultrasound examination was used in 19 cases. Conservative treatment appeared to be effective in 7 patients. The abscess developed in 4 patients. In 5 patients the diagnosis of AI was confirmed at the surgery. Opening and draining of the abscess was performed in 35 patients. The transabdominal opening of the abscess in combination with appendectomy was used in 19 patients. The median laparotomy, appendectomy and abdominal drainage were conducted in 2 patients with the break of the abscess into the abdominal cavity that led to the development of disseminated purulent peritonitis. The long-term results after the resolution of the infiltrate and opening of the abscess were analysed in 38 patients. The postoperative complications have developed in 29 patients, reoperation was performed in 7 of them. 2 of the 68 patients died after surgery. The total mortality rate was 2.9%, postoperative mortality-3.4%. Acute liver insufficiency (1) and intoxication (1) were the causes of death. 相似文献

The effect of tempering temperature on the structure, wear resistance, and corrosive properties of steel 08Kh14AN4MDB is studied.
The results of mechanical and corrosion tests are used for constructing an optimization matrix for determining the optimum
tempering temperature.

The effect of preliminary radiation-oxidation treatment on the current density and on the current-voltage characteristic of zirconium is studied. The contribution of the preliminary radiation-oxidation treatment to the change in the electrophysical characteristics is determined in heat and radiation-and-heat tests of zirconium in contact with water. 相似文献

A theoretical approach to the dynamic analysis of deactivation and aging of heterogeneous catalysts is proposed — analysis
of the rate derivative in a kinetic equation of a given form. Methodology was demonstrated for the simplest kinetic equations
— zero-and first-order. Regardless of the form of the kinetic equation for the dynamic model of deactivation, the rate constant
is a function of an independent reaction coordinate. The method can also be used for solving reactivation problems and for
explaining the dynamics of cation exchange in zeolite.
