ABSTRACT
Purpose@#This study aimed to assess incidental abnormal findings in the paranasal sinuses and anatomical variations of the ostiomeatal complex (OMC) on magnetic resonance imaging (MRI) scans. @*Materials and Methods@#MRI scans of 616 patients (mean age, 44.0±19.4 years) were evaluated. Prior to obtaining the MRI scans, a checklist of patients’ clinical symptoms was filled out after obtaining their consent. The Lund-Mackay classification was used to assess the paranasal sinuses and OMC. The prevalence of abnormal findings and their associations with patients’ age, sex, and subjective symptoms were analyzed by the chi-square test, independent-sample t-test, and analysis of variance. The level of significance was set at 0.05. @*Results@#Abnormal findings in the paranasal sinuses were detected in 32.0% of patients, with a significantly higher prevalence in males (P0.05). Epithelial thickening and retention cyst were the most common abnormal findings in the paranasal sinuses. According to the Lund-Mackay classification, 93% of the study population had normal sinuses (score0.05). @*Conclusion@#Considering the relatively high prevalence of abnormal findings in the paranasal sinuses, it appears that clinical symptoms alone are not sufficient to diagnose sinusitis. A more accurate strategy would be to assess radiographic images of the paranasal sinuses and use a classification system. Sinusitis should be suspected in patients receiving a high score in this classification.
ABSTRACT
Introduction: Health care systems depend critically on the size, skill, and commitment of the health workforce. Therefore, researchers have a close observation on the subjects which leads to an increase in the productivity of human resources. This study aims at determining the relationship between the quality of work life and the productivity of knowledge workers of the central field of Shiraz University of Medical Sciences, in order to determine the factors effective in the quality of their working life
Method: This cross-sectional study was conducted on 300 individuals selected by stratified random sampling method. On 761 knowledge workers of the central field of Shiraz University of Medical Sciences by using Timossi questionnaire of Quality of Work Life and Knowledge Worker Productivity Assessment questionnaire of Antikainen, during May and June 2011 The collected data were recorded by SPSS version 15 software and then it underwent statistical analysis using Pearson correlation. The P value level for statistical significance was set at 0.05
Results: In general, 50% of the knowledge workers were dissatisfied about their quality of work life, and the other 50% had little satisfaction. 18% of the staff were in an unfavorable condition and 82% had a poor productivity. Also, the quality of work life had a positively significant relationship with the productivity of human resources [r=0.568; P>0.001]
Conclusion: Most of the knowledge workers in the central field of Shiraz University of Medical Sciences had low productivity and quality of work life. Considering the relationship between the two variables, taking measures to improve the quality of work life can lead to more creative and profound planning in presenting services and, as a result, improving the productivity of the knowledge workers
ABSTRACT
Lipoma is a common tumor of soft tissue. Its location on the oral mucosa is rare, representing 1% to 5% of benign oral tumors although it is the most mesenchymal tumor of the trunk and proximal portions of extremities. Lipoma of the oral cavity may occur in any region. The buccal mucosa, tongue, and floor of the mouth are among the common locations. The clinical presentation is typically as an asymptomatic yellowish mass. The overlying epithelium is intact, and superficial blood vessels are usually evident over the tumor. Other benign connective tissue lesions such as granular cell tumor, neurofibroma, traumatic fibroma and salivary gland lesions [mucocele and mixed tumor] might be included in differential diagnosis. We present two cases of oral lipoma in unusual locations: one in junction of soft and hard palate and the other in tongue. Both were rare in the literature
