Objectives
The aim of the current study was to design a new simpler form of National Institutes of Health Stroke Scale (NIHSS) for use in emergency settings, and compare its predictive ability with original NIHSS score for mortality.Methods
A total of 152 consecutive patients with first ever ischemic stroke admitted to a university affiliated hospital were recruited. NIHSS score on admission was estimated and the predictive ability of NIHSS items for mortality at 28 days was evaluated by logistic regression. Stepwise discriminant analysis was performed on NIHSS items to obtain a discriminant function with the best discriminative ability for mortality. Further, receiver operating characteristics (ROC) curves were depicted to compare the new determined discriminant function with the original NIHSS score.Results
Cumulative rate of mortality was 11.8% for 28-day follow-up period. Among NIHSS items, scores of visual field, limb ataxia and extinction neglect were not associated with mortality (P > 0.05). On the contrary, level of consciousness-commands, language and gaze were determined as independent indicators of mortality (P < 0.05), and their coefficients on discriminant function were equal to 0.65, 0.44 and 0.30, respectively. In addition, area under the ROC curve of the calculated discriminant function was not statistically different from NIHSS score (P > 0.05).Conclusions
The suggested discriminant function, comprising NIHSS items of level of consciousness-commands, language and gaze, can predict 28-day mortality after ischemic stroke in a similar way to the original NIHSS score and can provide a baseline for stroke severity in emergency settings. 相似文献63.

Purpose: The aim of this prospective randomized controlled clinical study was to assess the crestal bone loss and the implant stability in implants that were placed by the osteotome technique compared with the conventional drilling technique. Materials and Methods: Forty‐six screw type Straumann SLA® oral implants (Straumann AG, Waldenburg, Switzerland) were inserted in the anterior segment of maxilla of 30 patients. The implant site was prepared randomly using either osteotome technique (test group) or the conventional drilling technique (control group). Radio frequency analysis (RFA) values at implant placement and after 3 months were recorded. The crestal bone loss was measured using digital subtraction radiography technique after 3, 6, and 12 months. Results: RFA demonstrated a statistically significant higher primary stability for implants in the osteotome group than that of the conventional group (p = .026) at the time of implant insertion. However, there was no statistically significant difference between both groups 3 months after the surgery (p = .06). At month 3, the osteotome group caused significantly more crestal bone loss than the conventional group (p = .04). At months 6 and 12, both groups had comparable bone levels (p = .29). Conclusion: Osteotome technique yielded higher primary stability than conventional drilling technique. However, this technique was not superior to conventional technique after 3 months. 相似文献

Background:
A relation has been established between infection with high-risk types of human papilloma virus (HPV) and development of cervical cancer. To estimate the risk of HPV infection for cervical malignancies, we conducted a case-control study in northeast Iran.Materials and Methods:
This study was carried out on 123 paraffin embedded blocks with exact diagnosis of squamous cell carcinoma (SCC). A total of 100 cervical tissue specimens with normal histopathology product of hysterectomy were also used as control. Both groups were tested for the presence of HPV DNA and HPV 16/18 subtypes using PCR assay.Results:
Large non-keratinising subtype of cervical carcinoma was the most frequent one (62.6%), followed by keratinising and small cell subtypes (27% and 10%, respectively). Overall prevalence of HPV infection in SCC of cervix was 34.2% (42 out of 123 cases). HPV 16 was the most common type in this group (21 cases, 17.1%), followed by HPV 18 (16 cases, 13%) and other subtypes (5 cases, 4.1%). In this study, overall prevalence of HPV infection in control group was 12% (including 3% HPV 16; 5% HPV 18 and 4% other subtypes).Conclusion:
Although association of HPV 16/18 and SCC of cervix was relatively higher than control group, compared with the previous study, the association between cervical SCC and HPV infection was significantly lower in our study; and possibly, the other risk factors play a major role in carcinogenesis of cervical carcinoma in this region. 相似文献68.

BACKGROUND: The purpose of this study was to determine the factors that can help predict risk of mortality in the first 24 h of coronary artery bypass grafting (CABG), because mortality within a few hours of surgery is a disastrous event for surgeons and the patient's family. METHODS: The study population consisted of 120 in-hospital mortality cases (1.07%) from 11,183 patients who underwent CABG from February 2002 to February 2006 by the same group of surgeons in a referral center. One group consisted of 40/120 (about 33.3%) patients who died during the first 24 h after surgery. The second group consisted of 80/120 patients (66.7%) who died between the 2(nd) and 30(th) day postoperatively. A set of data was gathered from the surgery database of the hospital and analyzed in a univariate model. RESULTS: Among the studied variables, only the following factors proved to be significant: previous percutaneous transluminal coronary angioplasty (PTCA), previous cerebrovascular accident (CVA), cardiopulmonary bypass (CBP) time, and postoperative atrial fibrillation (AF) (p =0.05). CONCLUSIONS: This study revealed that influencing factors in 24-h in-hospital mortality are previous PTCA, previous CVA, CBP time, and postoperative AF. It is interesting that influencing factors in global 30-day hospital mortality such as body mass index, diabetes mellitus, preoperative arrhythmia, ejection fraction, history of previous CABG and resuscitation, or catastrophic states like poor runoff coronary vessels, triple vessel disease or associated procedures like valve surgery were not significant in the first 24-h mortality when comparing with in-hospital mortality in this study. 相似文献

Rehabilitation of a patient with amelogenesis imperfecta using all-ceramic crowns: a clinical report
This article presents a patient with amelogenesis imperfecta rehabilitated with all-ceramic crowns following surgical and orthodontic intervention. The 6-year evaluation of the esthetics and function of the restorations showed evidence of isolated pulp exposure and crown fractures in the posterior areas. 相似文献
