Introduction
There is an increasing recognition that oral disorders might cause significant impact on life of patients. To date, there has been less focus on oral health?Crelated quality of life (OHR-QoL) measures in outpatient clinics for oral diseases.Aim
This study was carried out to test the assumption that patients with common tongue conditions would report a worse OHR-QoL than controls.Method
A total of 59 oral subjects with various tongue conditions and 44 controls were enrolled in this prospective study. Demographic, clinic, and laboratory findings of oral subjects were recorded, and an OHR-QoL questionnaire, named 14-item oral health impact profile (OHIP-14), was completed by oral subjects and controls at the outpatient clinics of four centers.Results
Median of OHIP-14 total scores of the oral subjects with common tongue conditions was 11 and that of controls was 4 (P?=?0.00) indicating that OHR-QoL was worse in oral subjects than in controls. Most (n?=?39, 66%) of the oral subjects had mild to distressing pain. Eating was the most commonly affected function. Oral subjects were arbitrarily divided into two groups. Group 1 (n?=?22) included patients with tongue conditions which were associated with candidal infections and the other patients formed Group 2 (n?=?34). A significant difference between Group 1 and Group 2 was observed only with respect to functional limitation (P?=?0.027), indicating that oral subjects of Group 1 had more functional limitation.Conclusion
Common tongue disorders were believed to be innocuous by most. When the influence of one of the most common form of oral disease (tongue conditions) on OHR-QoL was taken into consideration, OHR-QoL will provide an additional dimension and may help to improve the impact of a disease on an individual??s life. Moreover, we also encourage more extensive use of these OHR-QoL instruments for oral diseases at outpatient clinics. 相似文献Background and aims
Acute pain is the most common reason for visits to the emergency department (ED). The underuse of analgesics occurs in a large proportion of ED patients. The physician’s accurate assessment of patients’ pain is a key element to improved pain management. The purpose of this study was to assess if physicians’ perception of pain can improve with looking at the pain score of the patient marked on VAS.Study design
This was a single-center, cross-sectional prospective observational study, that took place in an academic ED.Methods
All adult ED patients presenting with a painful condition were enrolled to the study. In the first phase of the study, the physician rated his/her opinion about the patient’s pain on a 100 mm VAS, in a blinded fashion to the patient’s pain score. In the second phase, the physician rated his/her opinion after looking at the pain scale marked by patient.Results
587 patients (295, in first and 292, in second phase) were enrolled. The groups were not statistically different for demographic data. The physician’s perception of pain was lower than the patient’s pain score at both phases of the study. Insight of the patient’s pain score on VAS increased the physician’s pain perception significantly (p?=?0.03). During the second phase, physicians ordered significantly more analgesic medications to the patients (p?=?0.03).Conclusion
The physicians’ perception of the patients’ pain differs significantly from the pain that the patient is experiencing. VAS helps to bring the physicians impression of pain perception to the level of pain that the patient is actually experiencing and resulted in ordering more analgesics to the patients. Implementation of a pain assessment tool can raise the physician’s perception of the pain and may improve pain management practices and patient satisfaction.Methods: This prospective observational study recruited 223 women with singleton gestations scheduled for induction of labor at 37–42 weeks. Parity, body mass index, Bishop score, fetal head position, cervical angle measurement and cervical length was investigated to predict successful labor induction. Multiple regression analysis was performed to determine the parameters in the prediction of successful vaginal delivery within 24 hours.
Results: Forty-five patients were excluded because of cesarean section performed for other reasons than arrest of dilation or fetal head descent (43 fetal distress, 2 cord prolapsus). Remaining 178 patients were divided into two groups according to duration of delivery time. 139 patients delivered within 24 hours were classified as group I, 39 patients delivered after 24 hours were classified as group II. Percentage of multiparity was statistically significantly higher in group I than in group II [59 (42.4%), 9 (23.0%) respectively, p?=?0.009]. Cervical length was statistically significantly shorter in group I than in group II [23.1?±?7.42?mm, 31.3?±?6.83?mm respectively, p?<?0.001]. Bishop score was statistically significantly higher in group I than in group II [3 (1–4), 1 (1–4) respectively, p?<?0.001]. Posterior cervical angle was statistically significantly higher in group I than in group II [100.1?±?17.2, 92.7?±?21.4 respectively, p?=?0.007]. According to the fetal head position, there was no statistically significant difference in labor duration between the groups (p?=?0.787). In the multivariate regression analysis of variables, multiparity, cervical length and Bishop score were statistically significantly predictive in successful labor induction.
Conclusion: Multiparity status, cervical length, posterior cervical angle and Bishop score can predict successful labor induction, but fetal head position is not predictive in successful labor induction. 相似文献
