[Evaluation of the energy expenditure during walking in adolescent idiopathic scoliosis patients]

Scoliosis is one of the musculoskeletal disorders which influences the energy expenditure of patients during walking. In previous studies, metabolic cost of walking measured by oxymetry. Therefore, the aim of this study was to evaluate the energy expenditure of walking of the adolescent idiopathic scoliosis patients by use of monitoring the heart rate. This was observational comparative cross sectional study. Ten scoliotic patients and 10 normal subjects with comparable age, height and weight were recruited for this study. Energy consumption of walking in scoliotic and in normal subjects was evaluated using polar Electro Finland heart rate monitor. The heart rate during resting and walking and the walking speed were the parameters used for energy consumption based on the physiological cost index. The energy consumption of scoliotic subjects during walking based on PCI and THBI was higher than that of normal subjects, however, the difference was not statistically significant [p>0.05]. The results of this research showed that there was no significant difference between the PCI and THB index of normal and scoliotic subjects. Moreover, the walking speed of scoliotic patients did not influence by spinal deformation [p>0.05]

Morphometric changes of the socket after site preservation using nanobone and collagen membrane or stypro versus extraction alone

The long-term success of a dental implant relies on implant osseointegration into native and viable bone, implant placement in an ideal position, and optimal hard and soft tissue contour. This requires the presence of sufficient alveolar bone volume, good alveolar ridge [Practically with no sign of atrophy] and good surgical technique. The aim of this randomized controlled clinical study was to evaluate morphometric changes after different alveolar ridge preservation procedures.In this study, 33 patients who had single-rooted premolar, which needed to be extracted, were recruited. Patients were randomly divided into 3 groups and after tooth extraction the following treatments were administered: in group A: NanoBone and a collagen membrane; in group B: NanoBone and Stypro; and in group C: natural healing. The following clinical parameters were evaluated at baseline and 6 months after the extraction: buccolingual width, midbuccal height [with the use of a custom made stent] and width of keratinized gingiva. For data analysis, Paired t-test,one-way ANOVA and Tukey's tests were used.The average reduction in the buccolingual width, midbuccal height and keratinized gingiva was as follows: group A: 1.18 +/- 0.6, 0.64 +/- 0.92 and 3.45 +/- 1.75 mm; group B: 2.18 +/- 0.75, 0.73 +/- 0.78 and 4.73 +/- 0.9 mm; and group C: 1 +/- 0.89, 2.36 +/- 1.21 and 5 +/- 0.63 mm, respectively. Moreover, a significantly reduced resorption was found in both the buccolingual width and the width of keratinized gingiva in group A as compared to groups B and C [p<0.05].This study showed that the use of collagen membrane+Nano bone [group A] can significantly reduce the horizontal resorption of the alveolar ridge and keratinized tissue more effectively than stypro+Nano bone [group B] and blood clot alone and natural healing [group C]

Translation and cultural adaptation of the oxford hip score for Iranian population

In recent years, outcome assessment related to orthopedic surgeries has increasingly focused on patient reported questionnaires. The Oxford Hip Score [OHS], self administered questionnaire, is a reliable, valid, and responsive instrument for assessing hip in patients undergoing Arthroplasty. The study involved 105 adult Persian speaking patients admitted for primary Total Hip Arthroplasty in two hospitals in Isfahan in Iran from September 2009 until April 2011. All of them filled out their scales [Persian OHS, WOMAC, and SF12] in preoperative examination. Mean scores of OHS in first administrations was 42.7 +/- 12.7. The Persian OHS overall score demonstrated high reproducibility [ICC,0.93, P < 0.001] and internal consistency [CA, 0.94]. Persian OHS had high correlations with WOMAC total score [r = 0.86], function score [r = 0.86], and pain score [r = 0.79], the relationship between the Persian OHS and the WOMAC stiffness subscale was somewhat lower [r = 0.69]. The correlation coefficient between the Persian OHS and the PCS of the SF-12 in our study was moderate [r = 0.58]. Persian OHS had low correlation with MCS of the SF-12 [r = 0.40]. Persian OHS had high correlations with WOMAC total score, function score, and pain score. It had moderate correlation with PCS of the SF-12 and low correlation with MCS of the SF-12. Our study demonstrated the trans-cultural adaptation and validation of the Persian OHS is a reliable and practicable instrument for assessment of function and pain in Iranian patients with hip osteoarthritis

Total spine and posterior fossa MRI screening in adolescent idiopathic scoliosis [177 eases]

MRI screening for idiopathic scoliosis is controversial. Considering our clinical experiences, the results of MRI in all patients with idiopathic scoliosis were evaluated. In a prospective clinical study, all neurologically normal patients with idiopathic scoliosis screened by posterior fossa and total spine MRI. After excluding 9 patients for mild neurological findings, in other 177 patients [132 female, 45 male], the average age and curve angle was 15 +/- 2 years and 59 +/- 17 0.05]. Left convexity was significantly related to positive MRI findings [P=0.013]. In males with left convex curves, the probability of positive MRI findings was 8.8 folds other patients. Considering our results and other reported articles, it seems that routine MRI screening of all patients presenting as idiopathic scoliosis is necessary for detection of underlying pathologies

Osteoid osteoma of cervical spine in two adjacent vertebrae

Osteoid osteoma is a benign bone tumor, mainly seen in 10-30 years male. Spine is a relatively common site and almost always, posterior elements are involved. Plain X-Ray-, CT scan and Isotope scan help to identify and localize spine lesions. We described one 18 years old boy with 3 years low neck pain. Isotope scan, MRI and CT scan showed two lesions in C7 and T1. Gross inspection and histopathology examination confirmed osteoid osteoma in two adjacent vertebrae which has not been reported elsewhere in the literature
