Comparative Study
[Prevalence of cataract in 35-64 years old Kaunas city population].
The aim of the study was to determine the prevalence of lens opacity among 35-64 years old Kaunas population as well as to evaluate the stage and type of age-related cataract and its distribution in the groups of age and gender. ⋯ The lens opacities were found in 17.8% of males and 18.6% of females among investigated 35-64 years old population of Kaunas city. In the groups of both genders domination of nuclear cataract and the 1st stage of all forms of cataract was observed. The incidence of cataract increases significantly with age.

The aim of the study was to evaluate the impact of different treatment methods on survival of patients treated for advanced pancreatic cancer at Kaunas University of Medicine Hospital from 1987 to 2003. ⋯ Patients diagnosed with advanced pancreatic cancer in addition to surgical treatment should be treated by chemotherapy, concomitant chemoradiotherapy or radiotherapy.

Comparative Study
[Investigation of human papillomavirus, its types and variants].
Cervical cancer is one of the most common cancers in Lithuania. It is the fourth cancer in women according to the morbidity. The incidence rate of cervical cancer has been increasing in Lithuania since 1992. ⋯ It is important to notice that prevalence of HPV in women with high-grade squamous intraepithelial lesions was higher than in the control group. HPV 16 (55.8% in squamous cell carcinoma patients and 35.3% in cervical adenocarcinoma patients) and its European HPV 16 L83V variant were detected more frequently in cervical cancer patients. Studies on HPV, prevalence of its types and variants are very important for HPV based preventive strategies, especially for the vaccination.

Comparative Study
[Prevention of intestinal ischemia after abdominal aortic reconstructive surgery].
The aim of this study was to estimate rate of intestinal ischemic complications after abdominal aortic reconstructive surgery, to evaluate risk factors and to provide means of prevention of complication. ⋯ Study group consisted of 172 patients who underwent aortic reconstruction in 2000-2003 in the Department of Vascular Surgery of Kaunas University of Medicine Hospital. Six patients underwent intestinal ischemia in the postoperative period, i. e. 3.5%; four of them died. This indicated that 13% of patients died after abdominal aortic surgery. Ninety-four patients underwent operation for aortoiliac occlusive disease, colon ischemia occurred in 1 case (1.1%). Seventy-eight patients underwent abdominal aortic aneurysm; 33 patients -- ruptured aneurysm, and 45 -- aneurysm without rupture. In ruptured abdominal aortic aneurysm group with III degree colon ischemia there were 3 cases (9.1%); 2 of them died, which formed 11% of all deaths in this group. In the group of non-ruptured abdominal aortic aneurysm with III degree colon ischemia there were 2 cases (4.4%). Both patients died, which formed 50% of all deaths in this group. For all patients operated for abdominal aortic aneurysm, a. mesenterica inferior stump pressure was evaluated. In case of stump pressure 50 mmHg and more a. mesenterica inferior was ligated. If pressure was lower than 50 mmHg a. mesenterica inferior was reimplanted into vascular graft. Forty-nine reconstructions of a. mesenterica inferior were made in abdominal aortic aneurysm group: 25 in ruptured cases, and 24 in non-ruptured cases. Despite the fact that a. mesenterica inferior was reconstructed, 2 patients had colon ischemia after this reconstruction in the group of ruptured aneurysm. In the group of non-ruptured aneurysm, colon ischemia developed only after ligation of a. mesenterica inferior. We conclude that a. mesenterica inferior is very important for normal circulation of left colon. Correct evaluation of preoperative aortography, correct operative strategy, and reimplanted a. mesenterica inferior if it is necessary -- are the main means of colon ischemia prevention after abdominal aortic surgery.

Comparative Study
The influence of cardiopulmonary bypass on respiratory dysfunction in early postoperative period.
Pulmonary dysfunction is one of the most serious problems in an early postoperative period after cardiac surgery. This study was designed to reveal the impact of performed cardiopulmonary bypass on pulmonary function during early postoperative period by evaluating the intrapulmonary shunt. ⋯ Arterial hypoxemia and increase in intrapulmonary shunt (due to atelectasis) have proven that alterations in pulmonary function are found more often and are more pronounced in patients after surgery on cardiopulmonary bypass.
