Abstract: Non-contact anterior cruciate ligament (ACL) injury is one of the most common ligament injuries in the body. Many patients’ receive graft surgery to repair the damage, but have to undertake an extensive period of rehabilitation. However, non-compliance and lack of understanding of the injury, healing process and rehabilitation means patient’s return to activities before effective structural integrity of the graft has been reached. When clinicians educate the patient, to encourage compliance with treatment and rehabilitation, the only tools that are currently widely in use are static plastic models, line diagrams and pamphlets. As modern technology grows in use in anatomical education, we have developed a unique educational and training package for patient’s to use in gaining a better understanding of their injury and treatment plan. We have combined cadaveric dissections of the knee (and captured with high resolution digital images) with reconstructed 3D modules from the Visible Human dataset, computer generated animations, and images to produce a multimedia package, which can be used to educate the patient in their knee anatomy, the injury, the healing process and their rehabilitation, and how this links into key stages of improving graft integrity. It is hoped that this will improve patient compliance with their rehabilitation programme, and better long-term prognosis in returning to normal or near-normal activities. Feedback from healthcare professionals about this package has been positive and encouraging for its long-term use

Abstract: Objectives: To study the stress distributions in maxillary central incisor restored with Ni-Cr custom-made, gold custom-made, prefabricated titanium and prefabricated glass fibre dental posts subjected to oblique occlusal load at 100 N. Materials and Methods: Four three dimensional finite element models of a maxillary central incisor restored with Ni-Cr (Model I), gold custom-made (Model II), prefabricated titanium (Model III) and prefabricated glass fibre (Model IV) dental posts were constructed and oblique loading of 100 N was applied. Stress analysing at the along the centre of the post and post-surrounding structure interfaces were computed. Results: The result of this study indicates that the clinical three-dimensional image provided information about the behaviour of teeth under function in all directions. The results obtained from a finite element model on the restored system contain information about the stress distribution of each component of the restoration. The maximum von Mises stress distribution at post center was recorded with Model I (38.6 MPa), followed by Model III (22.4 MPa) and Model II (20.8 MPa) respectively; whereas the minimum amount of stress was noticed in Model IV (10.9 MPa). At post dentin interface, the highest von Mises stress distribution was noticed with Model I (29.8 MPa), followed by Model III (18.9 MPa) and Model II (18.8 MPa) respectively; whereas the smallest amount of stress was noticed in Model IV (10.16 MPa). Conclusions: Glass fibre posts generated the least amount of stress concentration at middle and apical part of the posts compared to other dental posts.

Abstract: Aims: The present study was taken up in carcinoma breast patients to evaluate clinical examination and Ultrasound in estimating the breast tumour size and axillary lymph node size taking histopathological examination as the gold standard. Material & Methods: The study carried out between December 2008 to June 2010 included thirty seven carcinoma breast patients. Ethics committee clearance obtained. Twenty four patients received neoadjuvant chemotherapy followed by surgery. 13 patients were taken up directly for surgery. Largest dimension of the primary tumour and axillary lymph nodes were assessed clinically, sonologically and histopathologically. Results were analyzed using paired-t test and Pearson correlation coefficient. Results: Clinical examination overestimated breast tumour size, while underestimated axillary lymph node size in majority of the patients. Sonological examination underestimated both breast tumour size and axillary lymph node size in majority of patients. There was strong correlation (r =.719, p=<.001) between clinical and histopathological breast tumour size, however for axillary lymph nodes the correlation was moderate (r=.536, p= .001). A moderate correlation (r=0.601; p=<.001) was observed between sonological and pathological breast tumour size, while strong correlation (r=.652, p <0.001) was found for axillary lymph nodes. For breast tumour, the difference between mean clinical and histopathological size was 0.01cm and statistically not significant (t=.064, p=.949). However, the difference between mean sonological and histopathological size for breast tumour was 1.10cm, and statistically highly significant (t=-3.93, p<.001). For axillary lymph nodes, the difference in mean size between clinical and histopathological assessment was 0.46 cm (p=0.007) as against mean difference of 0.48 cm between sonological and histopathological assessment (p=0.001). Conclusion: In the present study, for primary breast tumour size estimation clinical assessment was as good as histopathological examination, however, ultrasound was found to be inferior. Whereas for axillary lymph node size estimation both clinical assessment and ultrasound were indifferent .

Abstract: This review gives detail information about the mental foramen location, shape, size and numbers and its variation between races. Studies have shown that there are variations in the position of mental foramen in different populations. It may lie between the apices of premolars, below the apex of first or second premolars. This variations mandate accurate detection of foramen during examination and treatment plan stage. Foramen detection usually done by 2 dimension radiograph, with high chances of error. Three dimension radiograph provide the operator more precise location and dimension of the foramen that decrease the chances of the mental nerve damaging during the surgery.

Abstract: Radiological, ultrasonic methods of research and magnetic resonance tomography help estimate changes of internal structures of a lumbar department of a backbone at primary syndrome of the low back pain and compare importance of these methods. Materials and methods: 100 patients have been included in research from chronic and 100 patients with sharp vertebral low back pain (LBP) and group of comparison (100 persons). All patients have passed clinically - tool examination: radiography, MRI and ultrasound of a lumbar department of a backbone. 76 patients were carried out МРТ. Ultrasound of a lumbar department of a backbone was appointed before treatment (in 3 weeks). Results: The surveyed patients according to ultrasound had changes of internal backbone structures most often as disk protrusion. The greatest quantity of protrusions was diagnosed in patients with chronic LBP that were asymptomatic. Sharp LBP was most often caused by a nervous radical compression with hernia. In a group of practically healthy persons the percent of diagnosed disk protrusions was small. A positive clinical change by the end of treatment in patients with sharp and chronic LBP was combined with the reduction of quantity and protrusion sizes. Restoration of epidural and paravertebral blood flow was a good prognostic criterion of treatment efficiency. Research has shown high importance of ultrasound of a lumbar department of a backbone that can act as a screening method of diagnostics of primary syndrome of low back pain at an out-patient - polyclinic stage. The received about 90 % concurrence with МРТ data testifies to comparability of results and expediency of wider introduction of ultrasound of a backbone in practice of public health service.
