Since the definition of three-dimensional components of the scoliotic deformity, there have been important improvements in the surgical treatment of the problem. A derotation maneuver was proposed as a treatment option with CD instrumentation, but the reports of imbalance and decompensation with this system repopularized sublaminar wiring and translation as a corrective maneuver. Isola spinal instrumentation is one of the modern systems that utilizes vertebral translation instead of rod rotation. This study analyzes the results of 24 patients with idiopathic scoliosis who had been followed up for at least 2 years, and were surgically treated with titanium Isola Spinal Instrumentation in the Department of Orthopaedics and Traumatology, Ankara Social Security Hospital. Patients were grouped according to the King-Moe classification. Patients with type III, IV or V curves received only posterior instrumentation while this procedure followed anterior release and discectomy in the same session in patients with type I or II curves. A translation maneuver was utilized in the correction of scoliotic curves using the cantilever technique, either alone or supplemented by sublaminar wiring with Songer multifilament titanium cables. This study aimed to elucidate the effects of this technique in the frontal and sagittal plane curves and the trunk balance. The balance was analyzed clinically and radiologically by measurement of the lateral trunk shift (LT), shift of stable vertebra (SS), and shift of head (SH) in vertebral units (VU). The postoperative correction was significant in the frontal plane for all types of curves (p < 0.05). The postoperative correction was 80.9% +/- 9.5% in type III curves. Overall, the mean Cobb angle of the major curve value in the frontal plane was 66.9 degrees +/- 18.8 degrees, and it was corrected by 62.8% +/- 20.1%. The correction loss of Cobb angles in the frontal plane was 5.4 degrees +/- 5.5 degrees at the last follow-up visit. A normal physiologic thoracic contour (30 degrees - 50 degrees) was achieved in 83.3% of the patients and normal lumbar contour (40 degrees - 60 degrees) in 66.7% of the patients in the sagittal plane. The correction was found to be significant in all balance values (p < 0.05). The postoperative correction in LT values correlated with the correction of the Cobb angle values in the frontal plane. All patients had complete balance (SH: 0 VU and SS: 0 VU) or balanced curves (0 VU < SH, SS < 0.5 VU).Finally, the study concluded that the translation maneuver, especially when used with the cantilever technique, resulted in high correction rates in the frontal plane. Additionally, the technique was also successful in obtaining normal sagittal contours and correcting balance values. 相似文献

ObjectiveThe aim of this prospective study was to evaluate pre- and post-treatment MRI and CT findings of osteoid osteoma (OO) patients treated with radiofrequency thermo-ablation (RFTA) and to compare these findings with visual analog scale (VAS) scores.MethodsSixteen patients (4 females and 12 males; mean age of 18.87 ± 8.75 years (range: 8–37)) with OO were examined with CT and MRI, at baseline and at an average of 3 months following the procedure. On pre- and post-procedural CT and MRIs, OO-related findings were recorded. Treatment success was evaluated with VAS scores.ResultsBaseline VAS scores were 8 or 9 and follow-up scores were 0 or 1, indicating no early recurrences.Nidus diameters decreased significantly after the procedure (p = 0.027, p = 0.002, and p = 0.002; and p = 0.001, p = 0.001, p = 0.001 for AP, ML and CC nidus diameters for CT and MRI, respectively).The mean nidus volume were significantly decreased after the procedure (p = 0.001, for CT and MRI).On post-procedural images, cortical thickening, the signal intensity and contrast enhancement of the nidus and the extent of periostitis were significantly decreased (p = 0.019, p = 0.001, p = 0.001 and p = 0.034, respectively). There was no significant change in nidus calcification, perinidal cortical and intramedullary sclerosis, periosteal reaction, bone deformity, bone marrow and soft tissue edema, joint effusion and synovitis after the procedure (p = 0.253, p = 0.062, p = 0.245, p = 1, p = 1, p = 0.429, p = 0.371, p = 0.625, p = 1).ConclusionAlthough the changes in imaging findings may be helpful in early follow-up of OO patients treated with RFTA, these changes alone cannot be used with accuracy in predicting treatment response.Level of EvidenceLevel IV, Therapeutic Study. 相似文献

为探讨急性胆道感染时肝损害机制,本实验观察了大鼠实验性急性胆道感染对肝细胞线粒体的影响,以及伴随的肝脏储备功能改变。通过对肝细胞线粒体Ca~(2+)含量、溶酶体膜脆性、肝组织过氧化脂质含量、血清OCT,m-GOT酶活性和HPT试验的检测,发现急性胆道感染时肝细胞内存在着线粒体Ca~(2+)超载、溶酶体酶释放、脂质过氧化等,这些均可导致线粒体受累;血清OCT、m-GOT活性升高提示线粒体受损;HPT持续下降,表明线粒体受损同时,肝储备功能进行性受累。 相似文献

Background
Ginger (Zingiber officinale) is a well known and extensively used antioxidant in traditional remedies. In this study, we aimed to investigate the effects of ginger powder on ovarian folliculogenesis and implantation in rats.Methods
There were two study groups. In the 5-day treatment group (one estrous cycle), 100 mg ginger powder, 200 mg ginger powder or distilled water was given for 5 days to the three subgroups each containing seven rats. In the 10-day treatment group, same doses were given for 10 days (two estrous cycle) to the three subgroups each containing seven rats. At the end of the 5th and 10th days, ovarian volumes, ovarian weights, primordial follicles, antral follicles, atretic follicles, and corpus luteum counts were assessed. To evaluate the angiogenic effects of ginger, vascular endothelial growth factor (VEGF) and for the antioxidant effects of ginger endothelial nitric oxide synthase (eNOS) were examined in the ovaries and in the endometrium immunohistochemically.Results
In the 5-day treatment group, antral follicle count and ovarian stromal VEGF were significantly high in the 100 mg ginger subgroup in comparison to the control group (p < 0.05). In the 10-day treatment group, endometrial VEGF and ovarian stromal eNOS were significantly high in the 100 mg ginger subgroup in comparison to the control group (p < 0.05). There was no statistically significant difference at 200 mg ginger dose both in 5-day and 10-day treatment groups.Conclusion
The increases in the antral follicle count and ovarian stromal VEGF in the 100 mg/5-day treatment subgroup indicate that ginger have positive effects on folliculogenesis in short term with low dose. Additionally, ginger may enhance implantation in rats in long term with low dose. 相似文献77.

Aim Possible effects of garlic (Allium sativum) and black grape (Fructus vitis minuta) with known antioxidant potential on adenosine deaminase (ADA) activities were investigated in cancerous and noncancerous
human bladder tissues.
Methods The effects of garlic and black grape extracts on adenosine deaminase (ADA) activities were measured in 20 pairs of cancer
and adjacent normal human bladder tissues with and without pre-incubation with garlic and black grape extracts at different
concentrations.
Results No significant difference was observed between ADA activities in cancerous and non cancerous bladder tissues without plant
extract (5.85 ± 3.78 versus 7.63 ± 2.88, respectively). At the 1/3 and 1/1 plant extract/bladder tissue homogenate ratios,
the garlic extract completely abolished the ADA activity in both cancerous and noncancerous tissues. At the 1/3 plant extract/bladder
tissue homogenate ratio, the black grape extract decreased the activity significantly as compared to without extract (2.01 ± 1.30
versus 5.85 ± 3.78; p < 0.05 for cancerous tissue and 2.10 ± 1.66 versus 7.63 ± 2.88; p < 0.05 for noncancerous tissue) and, at the 1/1 plant extract/bladder tissue homogenate ratio, completely abolished the activity.
Conclusion Our results show that garlic and black grape have potential to inhibit ADA activity in both cancerous and adjacent normal
human bladder tissues.We suggest that this might be rational basis for the uses of garlic and black grape in the complementary
therapy of urinary bladder cancer. 相似文献

In this study, 143 cases of craniosynostosis are presented. There were 109 males and 34 females. The major complaints were skull deformity (92 patients), proptosis (38 patients) and microcephalus (32 patients). Neurological examination revealed the presence of optic atrophy in 24 patients and papilledema in 20 patients. Seventy-four patients (53%) had three or more suture closures, with the sagittal suture being the most commonly involved (20% of patients). All patients underwent surgery. Suture removal was performed in 131 patients (91.7%), suture removal plus orbital decompression in 34 (23.8%), and linear craniectomy plus wrapping in 12 (8.3%). The reoperation rate was 6.2 percent. During the follow-up period, preoperative papilledema and proptosis improved in 88.2 and 78.9 percent of patients, respectively. Skull deformity disappeared in 46.9 percent of patients, but remained unchanged in 16.6 percent. 相似文献
