The objective of this study was to evaluate the short-term results of surgical treatment in patients with acute aortic dissection. ⋯ The main risk factor for acute aortic dissection is the diameter of the aorta exceeding 4 cm (diagnosed in 73.7% of cases). The main postoperative complications are bleeding (42.1%), injuries of central nervous system (23.7%), and cardiogenic shock (18.4%).

Comparative Study
[Aortic root surgery: early postoperative results of different surgical techniques].
The aim of the study was to evaluate early postoperative results of different surgical techniques of aortic root surgery. ⋯ Different aortic root surgery techniques showed similar postoperative results. New aortic root surgery methods such as aortic root-preserving/sparing procedures and concurrent aortic valve leaflet repair or aortic root replacement with the bioprosthesis can be selected for a diverse class of aortic root pathology with low perioperative mortality rates and good early postoperative results.

Comparative Study
[Survival rate of patients with ascending aorta aneurysm and aortic valve regurgitation in the late postoperative period].
The aim of the study was to evaluate the long-term survival in patients undergoing surgical treatment for chronic aortic aneurysms with aortic regurgitation. ⋯ The analysis of patients' long-term survival demonstrated the efficacy of surgical treatment of such a complex pathology as chronic aneurysm of the ascending aorta with aortic valve regurgitation. The survival rate in the late postoperative period was higher in NYHA class III patients. The main causes of death were chronic heart failure and infective prosthetic endocarditis.

Comparative Study
Surgical treatment of pressure ulcers: an 11-year experience at the Department of Plastic and Reconstructive Surgery of Hospital of Kaunas University of Medicine.
The aim of this study was to evaluate morphological characteristics of pressure ulcers, methods of surgical treatment and its effectiveness in the Clinic of Plastic and Reconstructive Surgery of Kaunas University of Medicine Hospital. ⋯ In patients with paraplegia, the first pressure ulcer occurs after 74.79+/-61.34 months from the onset of the disease. Pressure ulcers most commonly occur over tuber ischii area. The most effective surgical treatment of pressure ulcers is closure of the wound using myocutaneous flaps (use of the hamstrings); fasciocutaneous flaps were the most commonly used method in patients who underwent surgery for the second time.

The aim of this review is to summarize the current knowledge on Hashimoto's thyroiditis and its pathogenesis and to introduce the readers to the basic concept of autoimmune thyroid disease. Hashimoto's thyroiditis and Graves' disease are different expressions of a basically similar autoimmune process, and the clinical appearance reflects the spectrum of the immune response in a particular patient. During this response, cytotoxic autoantibodies, stimulatory autoantibodies, blocking autoantibodies, or cell-mediated autoimmunity may be observed. ⋯ The significance of genetic component and nongenetic risk factors (pregnancy, drugs, age, sex, infection, and irradiation) in the development of Hashimoto's thyroiditis is also reviewed. Epidemiologic studies have demonstrated that the genetic component is important in the pathogenesis of Hashimoto's thyroiditis, although the pattern of inheritance is non-Mendelian and is likely to be influenced by subtle variations in the functions of multiple genes. Nongenetic risk factors (environmental factors) are also etiologically important, because the concordance rate in monozygotic twins is below 1.
