Randomized Controlled Trial Comparative Study
The effect of combined treatment methods on survival and toxicity in patients with pancreatic cancer.
In Lithuania, there were 476 new pancreatic cancer cases in 2005. Based on international scientific literature and the results of our retrospective studies, a prospective study has been designed. The aim of study was a prospective evaluation of the impact of two concomitant chemoradiation methods on the survival and the time to disease progression in patients diagnosed with resectable and unresectable pancreatic cancer and prospective evaluation of the safety of two concomitant chemoradiation methods for the treatment of resectable and unresectable pancreatic cancer. ⋯ RESULTS AND CONCLUSIONS. The treatment methods - radiotherapy and 5-fluorouracil or radiotherapy and gemcitabine - were equally effective when assessing the survival and time to disease progression in patients diagnosed with pancreatic cancer. Treatment of patients diagnosed with pancreatic cancer with radiotherapy and 5-fluorouracil was a safer approach than treatment with radiotherapy and gemcitabine, which induced more severe toxic adverse effects.

Comparative Study
Prevalence and causes of iron deficiency anemias in infants aged 9 to 12 months in Estonia.
To investigate the prevalence and causes of iron deficiency anemia in infants aged 9 to 12 months in Estonia. ⋯ Iron deficiency anemia is common among 9-12-month-old Estonian infants. The main risk factor for iron deficiency was birthweight less than 3000 g.

Comparative Study
The peculiarities of Pseudomonas aeruginosa resistance to antibiotics and prevalence of serogroups.
Pseudomonas aeruginosa is one of the most common nonfermenting aerobic gram-negative microorganisms identified in clinical specimens of hospitalized patients. The emergence of multidrug-resistant (MDR) Pseudomonas aeruginosa strains is a growing concern in hospital-acquired infections. Typing of strains is important for identifying the sources of infection as well as prevention of cross-infections and monitoring of the efficacy of antimicrobial therapy. The aim of this study was to evaluate the antimicrobial resistance and prevalence of Pseudomonas aeruginosa serogroups isolated at Kaunas University of Medicine Hospital, Lithuania. ⋯ The results of our study show that serogroup O:E was the most prevalent serogroup of Pseudomonas aeruginosa in our hospital, and its resistance to antibiotics was the highest.

The aim of the study was to compare the prevalence and severity of precancerous condition--gastric atrophy and intestinal metaplasia (IM) between Eastern European (Lithuania and Latvia) and Asian (Taiwan) countries in population older than 55 years. ⋯ The prevalence of H. pylori in the elderly population is still high in LT, LV, and TW. There are no significant differences in prevalence of gastric atrophy and intestinal metaplasia among TW, LT, and LV. There is a strong correlation between gastric atrophy and intestinal metaplasia.

Comparative Study
Prognostication of late left ventricular systolic dysfunction in patients with acute coronary syndrome during the acute period.
The aim of the study was to create the model of the combination of clinical and echocardiographic determinants during the acute period of acute coronary syndromes for the prognostication of the risk for left ventricular dysfunction after one year. We examined 565 patients with first-time acute coronary syndrome with no recurrence during one-year period. The studied group consisted of 496 patients, and the examined group--of 69 patients. ⋯ The application of our model in the prognostication of late left ventricular systolic dysfunction during the acute period of coronary syndrome showed that the model was reliable, since after one year, the prognosticated left ventricular systolic dysfunction was determined in the majority (84.3%) of patients. The designed mathematical model is simple and is based on standard clinical and echocardiographic findings, and the scoring system allows for the prognostication of the risk for late left ventricular systolic dysfunction in any individual patient. The prognostication of the risk for late left ventricular systolic dysfunction during the acute period of coronary syndrome may help in the planning of treatment and outpatient care in patients with acute coronary syndrome.
