Eighty-four calves with respiratory disease from 18 herds in different parts of Finland were chosen for a study evaluating the capacity of different respiratory pathogens to cause changes in different acute phase protein concentrations, white blood cell (WBC) count and clinical signs. The selected acute phase proteins were fibrinogen, haptoglobin, serum(More)
The purpose of this study was to report our experience in treating type II endoleaks after endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms. Two hundred eighteen patients underwent EVAR with a Zenith stent-graft from January 2000 to December 2005. During a follow-up period of 4.5 ± 2.3 years, solely type II endoleak was detected in 47(More)
Pathogens causing bovine respiratory tract disease in Finland were investigated. Eighteen cattle herds with bovine respiratory disease were included. Five diseased calves from each farm were chosen for closer examination and tracheobronchial lavage. Blood samples were taken from the calves at the time of the investigation and from 86 calves 3-4 weeks later.(More)
OBJECTIVE Ulcer healing is a seldom reported outcome in studies of critical leg ischemia (CLI). The aim of this study was to analyze local factors affecting ulcer healing time after infrainguinal bypass surgery (IBS) for CLI Fontaine IV. METHODS In this prospective single center cohort study, 110 patients (113 legs) undergoing IBS due to CLI with ischemic(More)
BACKGROUND The aims of the present study were to assess the usefulness of the Helicobacter felis mouse model in the evaluation of antimicrobial therapies and the effect of Helicobacter infection on gastric mucosal prostaglandin E2 release. METHODS Barrier-maintained BALB/c mice were infected with H. felis and treated with different antibacterial(More)
PURPOSE To assess the midterm results of endovascular repair of abdominal aneurysm (AAA) with a Zenith stent-graft. MATERIALS AND METHODS Between January 2001 and December 2005, a Zenith stent-graft was employed for endovascular repair of an infrarenal AAA in 206 patients. The mean patient age (+/-standard deviation) was 73.2 years +/- 7.3. Bifurcated(More)
BACKGROUND One-piece great saphenous vein (GSV) is the conduit of choice in infrainguinal revascularizations for critical limb ischemia (CLI). Unfortunately, adequate length of usable GSV is not always available. Despite inferior patency rates compared with GSV, prosthetic and arm vein conduits are generally considered usable. The purpose of this study was(More)
Our aim was to determine whether organizational changes could improve the outcome after ruptured abdominal aortic aneurysm (RAAA). Regional centralization and quality improvement in the in-hospital chain of treatment of RAAA included strengthening of the emergency preparedness and better availability of postoperative intensive care. During the(More)
OBJECTIVE This retrospective matched case-control study evaluated the consequences of multidrug-resistant Pseudomonas aeruginosa (MDR Pa) in critical leg ischemia (CLI) patients treated with infrainguinal bypass surgery (IBS). METHODS An outbreak of MDR Pa occurred on our vascular surgical ward during a 13-month period. Bacteria cultures positive for MDR(More)
Ruptured sinus Valsalva aneurysm was repaired in 13 patients (mean age c. 33 years). Dyspnea, chest pain, fatigue and palpitation were the most common symptoms and systodiastolic murmur, cardiomegaly and pulmonary congestion the most pertinent clinical findings. The pulmonary-to-systemic flow ratio averaged c. 2.5. Associated cardiac anomalies were(More)
