Corticobasal syndrome (CBS) is a clinical entity, classified as an atypical Parkinsonism, characterized by both motor and higher cortical dysfunctions. The clinical manifestation of CBS is associated with several pathologies, among which corticobasal degeneration (CBD) is the most common. The aim of our study was to elaborate on the possible vascular pathogenesis of CBS and consider types of vascular lesions in these cases. Several cases of vascular CBS are described in the literature. The majority of presented patients were affected by internal carotid artery (ICA) stenosis and ischemic strokes; few cases were associated with vascular malformations or autoimmune diseases. Vascular CBS is preceded by an abrupt onset. The clinical manifestation does not significantly differ with non-vascular CBS. Patients with vascular CBS are usually elderly; often with coexistent hypertension, dyslipidemia and diabetes mellitus. Inferring from our observations, cerebral hypoperfusion can play a significant role in neuropathological changes in neurodegenerative diseases. To the best of our knowledge paper is the first comprehensive review of vascular CBS and we are positive that our observations show that further research concerning the vascular pathogenesis of tauopathy atypical Parkinsonism is required.
Introduction: Acute appendicitis (AA) is one of the most common causes of urgent admission to the hospital. Clinically applicable classification distinguishes simple and complex inflammation. Among commonly used inflammation markers of AA, bilirubin concentration is not well studied and thus is rarely applied. Aim: To examine the association between increased serum total bilirubin concentration and the severity of AA. Material and methods: This retrospective study included 169 patients with a presumptive diagnosis of AA who were operated upon between 2015 and 2017. The determined study endpoints were simple complex inflammation and a different diagnosis after surgery. The Mann-Whitney U, Kruskal-Wallis, Fisher's exact, Spearman correlation coefficient and logistic regression tests and receiver-operating characteristics (ROC) were used in analyses. The area under the curve (AUC) was presented with 95% confidence intervals (95% CIs). Statistical significance was set at 0.05. Results: In total, 84 (49.7%) patients underwent laparotomy and 85 (50.3%) laparoscopy. After surgery, 45 (26.6%) patients had a diagnosis other than AA. Furthermore, 83 (49.1%) and 41 (24.3%) patients had simple and complex AA, respectively. The median bilirubin concentration was 0.56, 0.69, and 1.08 mg/dl in patients without AA, with simple, and complex AA, respectively (p < 0.01). The optimal cutoff for serum bilirubin concentration to predict AA severity was ≥ 0.94 mg/dl (AUC = 0.652; 95% CI: 0.543-0.761) with a 44.9% positive and 83.9% negative predictive value (p = 0.006). Conclusions: The serum bilirubin concentration should be considered as one of the possible markers of AA. Moreover, it can be used to predict the severity of AA.
Colorectal cancer (CRC) is one of the most predominant malignancies among the adult population. Most cases of CRC develop from non-malignant precursor lesions called adenomas over a long time, which provides an opportunity for prevention with screening programmes. The aim of the present study was to evaluate the knowledge and awareness level concerning colorectal cancer epidemiology, risk factors, symptoms, and prevention among young society in Poland. The knowledge was examined with an anonymous survey between February and March 2021. Statistical analysis was performed and differences were considered significant if the p-value obtained was smaller than the assumed level of significance p ≤ 0.05. Respondents were mostly female, living in a city, with a population of over 500 thousand. The study acquired information that might guide educators about knowledge deficit among young society in Poland. The results confirmed that education, family/friends history of CRC and a place of residence differentiate knowledge and awareness about CRC. They revealed a significant knowledge gap between rural and urban inhabitants as well as a medical and non-medical group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
