The aim of this study was to compare the accuracy, specificity and sensitivity of four commonly used methods of dental age estimation in a sample of south Indian adolescents and young adults aged between 14 and 30 years, with an age threshold of 18 years, using receiver operating characteristic curves (ROC) and the area under the curve (AUC). A total of 1070 orthopantomograms (535 males and 535 females) of adolescents and young adults of south Indian origin were collected retrospectively and interpreted. The effectiveness of each method was evaluated by using sensitivity (Se), specificity (Sp), likelihood ratios (LR+ and LR-) and AUC. Among all methods, I3M< 0.08 resulted in better values of AUC, Se and Sp which were 0.950, 91.5%, 97.8% and 0.950, 88.5% and 98.6% in males and females, respectively. For “stage H” of Demirjian’s system, the AUC, Se and Sp were 0.940, 84.9%, 97.7% and 0.930, 79.9% and 98.5% in males and females, respectively. The use of the Olze et al “stage 1 (or higher)” root pulp visibility and “stage D” of third molar eruption were not recommended in the studied population due to the greater percentage of third molars with incomplete mineralization in younger age groups and impaction. Taking into account the values of Se, Sp, both positive and negative LRs, we recommend the use of the cut-off value of I3M< 0.08 to discriminate adults and minors in south Indian adolescents and young adults. 相似文献

Arrangement of artificial teeth in a bilaterally symmetrical fashion with proper inclinations of teeth had been a challenging task for beginners. A variety of tools and guiding equipment have been developed to help students to learn teeth arrangement. Unfortunately, those tools were either costly or unsuitable for use with mean value articulators. This article attempts to introduce a simplified clinometer which can be attached to mean value articulator and can be used as a guide to arrange teeth in a bilaterally symmetrical manner by the undergraduates in both clinical and preclinical set-up. CLINICAL SIGNIFICANCE: Training of the future dentists in sound esthetic principles in a preclinical environment, using this device, will increase the final clinical efficacy of their work. AIM: The aim of this article is to provide a simple but effective device to undergraduate students to help them learn teeth arrangement easily and systematically. 相似文献

A case of brachial plexus injury after brachial arteriography is reported. Percutaneous catheterization of the brachial artery for angiography and intervention is performed when contraindications for the femoral approach exist. Access-related complications include injuries to the infraclavicular brachial plexus. This is often a result of a hematoma within the medial brachial fascial compartment leading to a compartment syndrome. Early recognition and prompt surgical management is vital to prevent permanent nerve damage. 相似文献

Histamine, an inflammatory mediator in its own right, may also be a marker for a more widespread systemic inflammatory process. In this study we have examined variations in plasma histamine concentrations produced during the course of cardiac surgery involving cardiopulmonary bypass, the relationship between these variations and intra-operative events. By assays of serum tryptase and CD-63 expression we have also attempted to identify the source of histamine. Histamine concentrations that were significantly raised from baseline level were demonstrated. These were elevated from the time of aortic cross-clamping and continued to be raised for 24 h postoperatively (p < 0.00625). This was associated with an increase in CD-63 expression (p < 0.025) (but not an increase in tryptase concentration) following aortic cross-clamping and protamine administration, suggesting that basophils are the source of histamine. 41% of patients had arrhythmias in the post bypass period. The rise in histamine levels was not related to the incidence of cardiac arrhythmias. 相似文献

PURPOSE: To report our experience with the diagnosis and management of Familial Exudative Vitreoretinopathy (FEVR) in a predominantly older Indian population.. METHODS: This prospective interventional non-comparative case series included 38 patients of FEVR and their 23 family members. The diagnosis was established by clinical examination, fluorescein angiography and family screening. Prophylactic photocoagulation/cryotherapy or surgical treatment was done depending on the severity of the disease. RESULTS: The mean age of the patients was 23.6 years. The fundus/fluorescein angiographic findings in 116 eyes of our 61 patients (6 eyes phthisical) were as follows: forty eight (41.4%) eyes had only peripheral avascular zone, 8 (6.9%) eyes had peripheral new vessels, and 35 (30.1%) eyes had retinal detachments (RD)--10 (8.6%) exudative, 5 (4.3%) tractional and 20 (17.2%) rhegmatogenous. Prophylactic photocoagulation or cryotherapy was done in 34 eyes for retinal holes, local exudative detachments and bleeding new vessels. All the eyes retained stable vision over a mean follow-up of 16 months. Only 14 RDs were suitable for surgery: scleral buckling, vitrectomy or both. The reattachment rate was 85.7% (12 of 14) and the best-corrected visual acuity (BCVA) improved to 5/60 or better in 50% of these eyes over a 2-year follow-up. CONCLUSIONS: FEVR appears to be more common than reported. Timely diagnosis and intervention is essential in view of the lifelong progression of the disease, late exacerbations, frequent involvement of family members, and poor surgical results. A high index of suspicion, family screening and early prophylaxis are recommended to prevent avoidable blindness from this underdiagnosed disease. 相似文献

Skin biopsies are usually undertaken to confirm a clinical diagnosis, to remove a lesion, and to determine the adequacy of excised tissue margin. A surgical margin is technically defined as the “edge” of the tissue removed. The term is especially pertinent when the tissue excised is suspected of being involved by a malignant process. One of the most important predictive and prognostic factors of a malignant lesion is whether the margins of the resected specimen are involved by the tumor or not. The purpose of this review is to provide an insight into grossing of a skin biopsy specimen with emphasis on techniques and reporting of excision biopsy margins. 相似文献
