ABSTRACT
Statement of the Problem: Jaw bone lesions are common pathologic conditions. The role of ultrasonography in evaluation of the extra-osseous lesions is confirmed, however, this imaging modality is not the diagnostic routine for the intraosseous jaw lesions
Purpose: The purpose of this study was to evaluate the efficiency of ultrasonography in diagnosis of intra-osseous jaw lesions concerning their size and content and also to study its correlation with the histopathological findings
Materials and Method: For this study, 15 patients with intra-osseous jaw lesions in the maxilla and mandible were selected from those referred to the Department of Oral Surgery. Panoramic imaging, computed tomography [CT] or cone beam computed tomography [CBCT] and ultrasonography [USG] were performed for all the lesions. The size of the lesions was measured by USG and then compared with CT or CBCT. Moreover, the correlation amongst the echographic patterns and histopathologic results was evaluated
Results: In 12 cases, size values were in complete agreement with CT or CBCT. The size of 3 lesions could not be measured by the radiologist due to the thickness of buccal cortical plate
Conclusion: Findings of this study suggested that USG might be feasible in estimating the size of intra-osseous jaw lesions with little underestimation. This study also confirmed that ultrasound imaging was a very useful imaging technique which could provide significant diagnostic information regarding the content of jaw bone lesions where the buccal bone thickness was thin enough
ABSTRACT
<p><b>OBJECTIVE</b>To compare the value of Glasgow coma scale (GCS) and cerebral state index (CSI) on predicting hospital discharge status of acute brain-injured patients.</p><p><b>METHODS</b>In 60 brain-injured patients who did not receive sedatives, GCS and CSI were measured daily during the first 10 days of hospitalization. The outcome of prognostic cut-off points was calculated by GCS and CSI using receiver operating characteristic (ROC) curve regarding the time of admission and third day of hospitalization. Sensitivity, specificity and other predictive values for both indices were calculated.</p><p><b>RESULTS</b>Of the 60 assessed patients, 14 patients had mild, 13 patients had moderate and 33 patients had severe injuries. During the course of the study, 17 patients (28.3%) deteriorated in their situation and died. The mean GCS and CSI in patients who deceased during hospitalization was significantly lower than those who were discharged from the hospital. GCS<4.5 and CSI<64.5 at the time of admission was associated with higher mortality risk in traumatic brain injury patients and GCS was more sensitive than CSI to predict in-hospital death in these patients. For the first day of hospitalization, the area under ROC curve was 0.947 for GCS and 0.732 for CSI.</p><p><b>CONCLUSION</b>GCS score at ICU admission is a good predictor of in-hospital mortality. GCS<4.5 and CSI<64.5 at the time of admission is associated with higher mortality risk in traumatic brain injury patients and GCS is more sensitive than CSI in predicting death in these patients.</p>
