Oral Cavity Cancer Tissues Differ in Isotopic Composition Depending on Location and Staging.

The aim of this paper was to characterise the isotopic composition of oral squamous cell carcinoma (OSCC) specimens of different areas of the oral cavity. Secondly, we assessed whether there was a correlation between clinical stages of OSCC and isotopic abundance. The IRMS procedure was performed on 124 samples derived from 31 patients with OSCC of 15 N and 13 C to assess the isotopic composition.

Characteristic of Oral Squamous Cell Carcinoma Tissues Using Isotope Ratio Mass Spectrometry.

Overall prognosis for patients with oral squamous cell carcinomas (OSSC) is still unfavourable. However, there is a hope that a novel diagnostic method may establish better cancer biology characteristics. The aim of this study was to evaluate the isotope ratio of nitrogen and carbon in OSSC as compared to margin and healthy tissue.

Screening test for extracranial carotid lesions' detection in patients of an outpatient vascular clinic.

Purpose The objective of the study was to evaluate the frequency and severity of atherosclerotic lesions in extracranial sections of carotid arteries and to determine the level of the correlation between these lesions and symptoms of cerebral ischemia. Secondly, to identify the most common risk factors of ischaemic stroke occurrence in population of patients of vascular outpatient clinic. Material and Methods Prospective study was conducted on a group of 1,000 people (217 women and 783 men), aged 50 to 86 years, the average age was 62 years (± 9.

Characteristics and risk factors of bike-related accidents: Preliminary analysis.

Background: The growing popularity of cycling not only enhances self-efficacy, physical well-being and improves quality of life, but it also leads to the increasing number of bike-related injuries.

Objectives: The aim of this study was to characterize the population of cyclists in Poland, assess the occurrence of safety behaviors among them and to precise the risk factors for bike accidents. Additionally, we analyzed bike-related injuries.

Gender-related risk factors for perioperative stroke after carotid endarterectomy in symptomatic patients.

Background: Carotid endarterectomy (CEA) is a surgical procedure used in ischemic brain stroke prevention in patients with symptomatic and asymptomatic severe carotid artery stenosis.

Objectives: This study compares perioperative stroke or death rate after carotid endarterectomy (CEA) in male and female patients, and determines risk factors for perioperative incidents in women and men.

Material And Methods: The outcome of surgical treatment of 269 consecutive symptomatic patients (181 men and 88 women) treated from January 2004 to August 2008 in the Department of Vascular, General and Oncologic Surgery was analyzed.
