Obsessive-compulsive symptoms are common phenomena in society and they have negative effects on individual's function. The aim of the present study was to investigate the predictive power of some potential predictors of obsessive-compulsive symptoms subtypes. In this study, the correlations of meta cognitive beliefs, maladaptive schemas and worry with obsessive-compulsive symptoms subtypes were examined.
eighty students of Tehran University of Medical Sciences were selected based on cluster sampling. The students completed Obsessive-Compulsive Inventory-Revised(OCI-R), Meta Cognition Questionnaire(MCQ), Young Schema Questionnaire-Short Form(YSQ-SF) and Penn State Worry Questionnaire(PSWQ). Correlation and regression analyses were used to analyze the data.
All predictive variables significantly correlated with obsessive- compulsive symptoms. Results from stepwise regression showed that meta cognitive beliefs entered in regressional models more than other variables. Worry had the lowest weight in prediction of the dependent variables. Predictors had different weights in predicting of subtypes. Predictive formulate were reported for each of subtypes and the total score of obsessive-compulsive symptoms.
Results from this study about correlations of meta cognitive beliefs, maladaptive schemas and worry with obsessive-compulsive symptoms were consistent with cognitive theories in this field. The roles of each predictor and its clinical applications are discussed.
Sinonasal malignancies are rare tumours, which can be resected using an open or endoscopic approach. The current study evaluated the outcome of both approaches.
A total of 160 patients with malignant nasal tumours were evaluated in an academic tertiary care hospital. The patients were allocated to ‘open’ or ‘endoscopic’ surgery groups, based on the surgical approach employed. The following data were evaluated and compared: patient and tumour characteristics; oncological treatments; and oncological outcomes, including complications, surgical margin, recurrence, overall survival and disease-free survival.
The maxillary sinus was the most common tumour location and squamous cell carcinoma was the most common histopathology-based diagnosis. Younger patients had lower grades of tumour. Higher survival rates were significantly related to lower tumour stages in both surgery groups. There were no differences between the two relatively similar groups in terms of surgical margin, the need for adjunctive therapy, and recurrence and survival rates. In addition, multivariate logistical regression analysis indicated no correlations between the type of surgical approach employed and the rates of recurrence and complications.
Endoscopic surgery for sinonasal malignancies is comparable to the conventional open approach in carefully selected patients.
