Aim The aim of this survey was to compare Chinese natives and foreign inhabitants in Chengdu, China, with respect to: (1) attitudes towards dental appearance, (2)subjective orthodontic treatment need, and (3) the main factors influencing orthodontic treatment need.Methodology A total of 522 subjects, including 227 foreign inhabitants and 295 Chinese natives in Chengdu participated in the survey. A simple random sampling method was adopted and a face-to-face interview was conducted at some public sites using a questionnaire. Data was entered by two persons synchronously using Epidata 3.0, and SPSS 13.0 was used to analyze these data.Results 89.0% of foreign inhabitants were satisfied with their teeth compared to only 46.8% of Chinese natives.Females were more dissatisfied with their teeth than males.Chinese natives put improving appearance as the top priority (55.9%) for seeking orthodontic treatment;however, in foreign inhabitants, the main reason for seeking treatment was to improve masticatory function (44.1%), followed by "to be pretty" (35.2%). The importance of well-aligned teeth and self-perception of psychosocial impact of malocclusion were the same two main factors influencing subjective orthodontic treatment need (P<0.05) in foreign inhabitants and Chinese natives. Subjective orthodontic treatment need between the two target groups was significantly different (P<0.05).Conclusion (1) It was very common that Chinese natives were dissatisfied with their dental appearance, and their subjective orthodontic treatment needs were high. (2) There were some differences in orthodontic treatment motives between the two target groups. (3) There were differences in subjective orthodontic treatment needs between foreign inhabitants and Chinese natives. However, the prominent influential factors were almost the same. There may be benefit to understanding subjective orthodontic needs of different races. 相似文献

Background: Orbital cavernous haemangioma (OCH) is one of the most common primary orbital tumours in adults. They can encroach on intraorbital or adjacent structures and be considered ‘anatomically’ malignant.Aims: To report a series of patients that were all managed surgically, with possible specificities and propose predictors of treatment outcome.Methods: We realised a hospital-based retrospective case review including data from 76 patient files.Results: The mean age was 37.8 years. Unilateral proptosis was observed in all patients. Visual loss was found in 32 patients (42.1%). Findings on eye examination included lagophthalmos (76.3%), blepharoptosis (21.1%), complications of corneal exposure (19.6%), strabismus (13.2%) and fundoscopic abnormalities (60.5%). Abnormal fundoscopy was significantly associated with decreased visual acuity (VA) (p?<?.001). Small tumours were predominant (65.8%) and size was associated with VA (correlation coefficient r?=??0.5, p?<?.001). Surgery was mainly by lateral orbitotomy (94.7%), with early post-operative complications in 18 patients (23.7%). Multivariable analysis showed that tumour size, preoperative VA and abnormal fundoscopy were significantly associated with postoperative VA.Conclusion: Clinical and radiological profiles are consistent. Tumour size, preoperative VA, and abnormal fundoscopy seem to be important factors that could influence outcome expectations. Surgical management is still predominantly by open approaches. Severe complications remain rare. 相似文献

ObjectiveThis study aimed to analyze the factors affecting postoperative hearing results of patients with otosclerosis.MethodsMedical records of 245 patients with clinical otosclerosis who underwent stapes surgery at our center from January 2009 to December 2018 were reviewed. The retrospectively collected data included patients’ demographics, clinical characteristics, pre- and postoperative audiometric data, size of preoperative air-bone gap (ABG) (small/large). The patients were categorized into two groups according to the postoperative functional outcome: Group 1 consisted of patients with a postoperative ABG of ≤10 dB and Group 2 comprised those with a postoperative ABG of >10 dB. Evaluation of factors affecting functional outcome were performed by logistic regression analysis. Receiver operating characteristics (ROC) curve was generated to obtain the cut-off points for preoperative ABG.ResultsThere were no statistically significant differences between the two groups in terms of age group (p = 0.393), gender (p = 0.670), operated side (p = 0.370), and laterality of disease (p = 0.607). There were 42 patients (31.6%) with a small ABG and 91 patients (68.4%) with a large ABG in group 1, and six (13.6%) and 38 patients (86.4%), respectively in group 2. There was a statistical significant difference between the groups in terms of the size of preoperative ABG (p = 0.020). In group 1, the mean preoperative air conduction (AC) threshold and preoperative ABG were significantly lower than in group 2 (p < 0.001 and p < 0.001, respectively). There was no statistically significant difference between the groups in terms of the preoperative bone conduction (BC) threshold (p = 0.406). Preoperatively, the AC threshold and large ABG were found to be significantly poorer prognostic factors (p < 0.001; 95%CI: 1.031–1.210 and p = 0.037; 95%CI: 1.063–7.023, respectively). Preoperative ABG cut-off threshold for functional success was found to be 34.5 dB. The functional success rate was significantly higher in patients with a preoperative ABG of <34.5 than in patients with a preoperative ABG of ≥34.5 dB (p < 0.001).ConclusionThe preoperative AC threshold and large ABG were poor prognostic factors for postoperative hearing outcome in patients with otosclerosis. The functional outcomes were similar in patients with a preoperative small ABG and those with a preoperative ABG of <34.5 dB. A preoperative ABG cut-off value of <34.5 dB should be possibly considered as a parameter for predicting surgical success in otosclerosis and seems to be useful in clinical practice. 相似文献

Objective: To adapt the Satisfaction with Amplification in Daily Life questionnaire into Chinese (the SADL-CH questionnaire) and investigate hearing-aid satisfaction in a group of adult Hong Kong Chinese fitted with free hearing aids. Design: Cross-sectional survey. Study sample: One hundred and twenty-five experienced hearing-aid users. Methods: The subjects completed a history form seeking demographic data and a questionnaire combining the SADL-CH instrument with questions seeking subjects’ subjective ratings of satisfaction with some hearing-aid features and overall satisfaction with their hearing aid. Results: The SADL-CH questionnaire had a good internal consistency reliability estimate (α =?0.79) comparable to that of the original version. SADL-CH scores were observed to have significant correlations with other satisfaction ratings on some hearing-aid features and the overall satisfaction measure. A high degree of test-retest reliability (intraclass correlation coefficient =?0.79) was observed. Confirmatory factor analysis revealed that the SADL-CH questionnaire had a four-factor structure. Interim norms were derived for the SADL-CH questionnaire. The level of hearing-aid satisfaction in Chinese adults was generally lower than that reported in studies conducted among Western populations. Conclusion: The SADL-CH questionnaire is a reliable and valid instrument for measuring hearing-aid satisfaction. 相似文献

OBJECTIVES/HYPOTHESIS: Reports comparing case mix, treatments, and outcomes between different countries are uncommon in head and neck oncology. Prospective databases of unselected patients from regional cancer centers in southeastern Ontario, Canada, and southeastern Norway were compared. STUDY DESIGN: Retrospective comparative study of two prospective databases. METHODS: The case mix, treatments, and disease-specific mortality were compared using frequency tables, Kaplan-Meier survival curves, and the log rank test.RESULTSThe case mix, except for differences in oral cavity, oropharynx, and the recorded tumor (T) category, was similar, and the treatments were different. There was no statistical difference in overall survival for all patients, as well as for some sites. CONCLUSIONS: The results of treatments, based on different overall treatment polices, for all patients were similar. The differences in recorded T category with no statistical difference in overall survival suggest a difference in staging assignment and raises a question about the reliability of the TNM staging process. 相似文献

IntroductionObstructive sleep apnea syndrome is a common condition in childhood and if left untreated can result in many health problems. An accurate diagnosis of the etiology is crucial for obstructive sleep apnea treatment success. Functional orthodontic appliances that stimulate mandibular growth by forward mandibular positioning are an alternative therapeutic option in growing patients.ObjectiveTo perform a literature review about the effects of functional orthodontic appliances used to correct the mandibular deficiency in obstructive sleep apnea treatment.MethodsThe literature search was conducted in June 2020 using Cochrane Library; PubMed, EBSCO (Dentistry & Oral Sciences Source), LILACS Ovid; SciELO Web of Science; EMBASE Bireme and BBO Bireme electronic databases. The search included papers published in English, until June 2020, whose methodology referred to the types and effects of functional orthopedic appliances on obstructive sleep apnea treatment in children.ResultsThe search strategy identified thirteen articles; only four articles were randomized clinical studies. All studies using the oral appliances or functional orthopedic appliances for obstructive sleep apnea in children resulted in improvements in the apnea-hypopnea index score. The cephalometric (2D) and tomographic (3D) evaluations revealed enlargement of the upper airway and increase in the upper airspace, improving the respiratory function in the short term.ConclusionFunctional appliances may be an alternative treatment for obstructive sleep apnea, but it cannot be concluded that they are effective in treating pediatric obstructive sleep apnea. There are significant deficiencies in the existing evidence, mainly due to absence of control groups, small sample sizes, lack of randomization and no long-term results. 相似文献

OBJECTIVES: To find clinical factors related to administration of substandard treatment in older patients with head and neck cancer. STUDY DESIGN: Historic cohort. METHODS: Patients of 70 years of age of older with diagnosis of resectable head and neck cancer were included. Treatment offered to patients was classified as standard or substandard by experienced surgeons. Relation of age, clinical stage, comorbidities, performance status, and treatment with substandard treatment was explored. The effect of substandard treatment on survival was assessed. RESULTS: Three hundred twelve patients were included. Substandard treatment was offered to 19.9% of patients. Associated factors related to selection of substandard treatment were higher age, oro/hypopharynx tumor site, severe comorbidity, advanced clinical stage, and low Karnofsky Index. Patients submitted to substandard treatment had lower overall and cancer-specific survival (45.9% vs. 19.9% and 63.0% vs. 33.1%, respectively). CONCLUSION: Selection of substandard treatment decreases overall and cancer-specific survival. Selecting substandard treatment for reasons such as chronologic age, tumor site, or moderate or mild comorbidities worsen patient prognosis. 相似文献

The proposal of this basic protocol is an attempt to reach better agreement and uniformity concerning the methodology for
functional assessment of pathologic voices. The purpose is to allow relevant comparisons with the literature when presenting
/ publishing the results of voice treatment, e.g. a phonosurgical technique, or a new / improved instrument or procedure for
investigating the pathological voice. Meta-analyses of the results of voice treatments are generally limited and may even
be impossible owing to the major diversity in the ways functional outcomes are assessed. A multidimensional set of minimal
basic measurements suitable for all “common” dysphonias is proposed. It includes five different approaches: perception (grade,
roughness, breathiness), videostroboscopy (closure, regularity, mucosal wave and symmetry), acoustics (jitter, shimmer, Fo-range
and softest intensity), aerodynamics (phonation quotient), and subjective rating by the patient. The protocol is elaborated
on the basis of an exhaustive review of the literature, of the experience of the Committee members, and of plenary discussions
within the European Laryngological Society. Instrumentation is kept to a minimum, but it is considered essential for professionals
performing phonosurgery.

ObjectivesThis study is to evaluate the dental arch relationship and palatal morphology of unilateral cleft lip and palate patients by using EUROCRAN index, and to assess the factors that affect them using multivariate statistical analysis.MethodA total of one hundred and seven patients from age five to twelve years old with non-syndromic unilateral cleft lip and palate were included in the study. These patients have received cheiloplasty and one stage palatoplasty surgery but yet to receive alveolar bone grafting procedure. Five assessors trained in the use of the EUROCRAN index underwent calibration exercise and ranked the dental arch relationships and palatal morphology of the patients' study models. For intra-rater agreement, the examiners scored the models twice, with two weeks interval in between sessions. Variable factors of the patients were collected and they included gender, site, type and, family history of unilateral cleft lip and palate; absence of lateral incisor on cleft side, cheiloplasty and palatoplasty technique used. Associations between various factors and dental arch relationships were assessed using logistic regression analysis.ResultDental arch relationship among unilateral cleft lip and palate in local population had relatively worse scoring than other parts of the world. Crude logistics regression analysis did not demonstrate any significant associations among the various socio-demographic factors, cheiloplasty and palatoplasty techniques used with the dental arch relationship outcome.ConclusionsThis study has limitations that might have affected the results, example: having multiple operators performing the surgeries and the inability to access the influence of underlying genetic predisposed cranio-facial variability. These may have substantial influence on the treatment outcome. The factors that can affect unilateral cleft lip and palate treatment outcome is multifactorial in nature and remained controversial in general. 相似文献

Clinical features and outcome of the tall cell variant of papillary thyroid carcinoma 总被引:1,自引:0,他引:1
OBJECTIVES: To study the clinical features and outcome of the tall cell variant (TCV) of papillary thyroid carcinoma (PTC). STUDY DESIGN AND METHODS: A single-institution retrospective analysis was performed to review patients with TCV and the usual type of PTC diagnosed from 1960 to 2000. RESULTS: Fourteen of 1,108 patients (median follow-up, 8.9 yr) diagnosed with PTC had TCV. Ten were female, and four were male, with a mean age of 53.7 (33-81) years. All were ethnic Chinese. Compared with the usual PTC cohort, TCV patients presented at an older age (mean, 53.7 vs. 45.2 yr; P = .015). They had a higher rate of extrathyroidal extension (78.6% vs. 43.4%, P = .009), tracheal invasion (28.6% vs. 9%, P = .034), and carotid vessel invasion (14.3% vs. 1.5%, P = .021). TCV patients had more frequent gross (42.9% vs. 17.2%) and microscopic (14.3% vs. 6%) postoperative locoregional residual disease (P = .008). They also had a higher percentage of stage III and IV disease (American Joint Committee on Cancer, 6th ed) (74.3% vs. 31.3%, P = .009). Ten-year local failure-free, regional failure-free, and metastasis-free survival were worse in the TCV group (78.6% vs. 88.8%. P = .017; 53.0% vs. 85.9%, P < .0001; 35.7% vs. 92.1%, P < .0001, respectively). The 10-year cause-specific survival was also lower in TCV patients (48.2% vs. 93.4%, P < .0001). CONCLUSION: TCV presents at a higher stage with more advanced local disease. It has a higher risk of locoregional and distant relapse and a worse overall survival rate. Stratification by stage reveals that TCV has significantly higher mortality compared with PTC for stage IV disease. Aggressive treatment and close follow-up of these patients is necessary. 相似文献
