Most studies evaluating the efficacy of atrial fibrillation (AF) ablation report follow-up periods of 1 year to 2 years, but few report long-term results of > or =5 years after ablation. Therefore, we evaluated the long-term efficacy (i.e., >5 years) of segmental antrum pulmonary vein isolation (PVI) for paroxysmal AF.…

INTRODUCTION: Multifocal motor neuropathy with conduction block is an immune-mediated motor neuropathy, which usually responds to intravenous immunoglobulin. However, efficacy of long-term intravenous immunoglobulin is controversial. Our aim was to establish the long-term effects of intravenous immunoglobulin therapy o…

BACKGROUND/AIMS: This study was undertaken to evaluate changes in the seroepidemiological pattern of Helicobacter pylori in a group of Turkish children over a span of 10 years. METHODS: A total of 403 (219+184) serum samples were obtained from a primary school located in the urban part of Ankara in 1990 and 2000. All…

OBJECTIVES: The diagnostic and therapeutic approaches to patients with acute upper gastrointestinal bleeding have been improved during the last decades. The aim of this study was to compare the aetiology and clinical outcome of acute upper gastrointestinal bleeding (AUGIB) between two distinct periods during the last 1…

The aim of this study was to emphasize the utility and prove the accuracy of rapid diagnosis at the outpatient clinic for breast tumors by fine needle aspiration cytology [FNAC]. Rapid diagnosis for breast tumors by FNAC is performed on the same day just after mammography and echonography are carried out at our hospita…

BACKGROUND: Given the lack of studies of acetabular defect reconstruction in primary total hip arthroplasty (THA) using tantalum augments, this study aims to evaluate clinical and radiographic results for treatment with tantalum augments to reconstruct acetabular defects in primary THA. METHODS: We retrospectively rev…

BACKGROUND AND PURPOSE: The rising cost of health care is of universal concern. If the cost effectiveness of conventional and novel radiotherapeutic strategies is to be established we need to have confidence in our estimates of both cost and effectiveness. The purpose of this study is to explore the degree of consisten…

OBJECTIVE: To investigate the inpatient pulmonary hypertension (PH) surveillance in a single center of cardiovascular hospital during last ten years. METHODS: In this retrospective analysis, data from patients with discharge diagnosis as PH from Jan. 1996 to Dec. 2005 were collected. RESULTS: A total of 7085 out of 1…

Alzheimer's disease (AD) is the most common cause of dementia in the elderly, with a prevalence of 5 % after 65 years of age, increasing to about 30 % in people aged 85 years or older. It is characterized by progressive cognitive impairment, including impaired judgment, decision-making and orientation, and in some case…

The last 10 years have seen resurgent industry activity in discovery and development of new drugs for the treatment of tuberculosis (TB), a growing widespread and devastating (more than 2 million deaths annually) bacterial infection that is of increasing concern in developing and developed nations alike. This review de…

In the last 10 years, 605 celiomesenteric arteriographic examinations were done at Hôtel-Dieu de Montréal, including 236 for suspected pancreatic disease. Sixty patients with histologic proof of malignant neoplasm had a positive arteriographic examination while 136 had benign disease of the pancreas and 40 ot…

In the last 10 years we have come to appreciate the central role that phosphatidylinositol (PI)-3,4,5-P(3)plays in regulating a vast array of biological responses to extracellular signals. The level of this phospholipid is low in resting cells but increases rapidly in response to growth factor/cytokine-stimulated plasm…

Recent trends in cesarean section deliveries in Canada were explored using 1970-1988/89 hospitalization data from Statistics Canada's morbidity data base. The rate in Canada increased from 5.8 cesarean sections per 100 hospital deliveries in 1970 to 19.5 in 1988/89 and paralleled the increase in rates seen in the Unite…
