Ninety segments in 15 patients met the inclusion criteria (average age at instrumentation 46.3 mo [range, 29-60 mo]). Forty segments had no screws and 50 had at least 1 screw. Pedicle length and vertebral body diameter had significantly increased in both groups, whereas spinal canal parameters did not change significantly. No significant difference was observed between the growth rates in levels with or without screws in pedicle length, vertebral body diameter, or spinal canal parameters (anterior-posterior and interpedicular diameters, and area).\n\nConclusion. Pedicle screw instrumentation performed before the age of 5 years does not cause a negative
effect on the growth of pedicles, the transverse plane of the vertebral body, or the spinal canal. It can MRT67307 be safely performed in selleckchem the treatment of deformity in this age group.”
“The purpose of this cross-sectional study involving 42 women between
20 and 39 weeks gestation was to compare transvaginal ultrasound (TVUS) vs. magnetic resonance imaging (MRI) in the assessment of cervical length measurement during the second half of pregnancy and to evaluate the reproducibility of cervical measurements obtained through MRI. Cervical length was measured through TVUS by a single examiner. On the same day, all women also had MRI and cervical length was assessed by two independent blinded observers. There were no significant differences in the mean cervical length obtained through TVUS and MRI (paired t-test, p = 0.191). The Bland-Altman test indicated concordance between measurements obtained through methods as well as good intra- and interobserver reproducibility for MRI measurements. Intraclass correlation coefficient was 0.990 (95% confidence interval [CI]: 0.982 to 0.995; p < 0.001) for measurements performed using MRI by two different observers and 0.995 (95% CI: 0.991 to 0.997; p < 0.001) for measurements performed using the same method
by a single operator. Cervical length measured through TVUS and MRI does not differ significantly. There is a good reproducibility of cervical measurements obtained through MRI. (E-mail: crpires@ uol.com.br) (C) 2010 World Federation for Ultrasound in Medicine & Biology.”
“Objective: To use the ENZIAN classification for preoperative estimation selleck of laparoscopic operating time in patients with deeply infiltrating endometriosis (DIE).\n\nStudy design: Retrospective study of women with DIE (n = 151) who underwent laparoscopic surgery.\n\nResults: 151 of 470 patients had DIE (n 205 lesions) exclusively in compartments A (rectovaginal septum, vagina), B (sacrouterine ligament to the pelvic wall) and C (rectum, sigmoid colon). These laparoscopically treated lesions were used to calculate a model for estimating operating time for DIE, assuming complication-free procedures (overall significance for model’s predictive power: P < 0.001). The error of estimation for the operating time prediction is 0 +/- 35.35 min (mean +/- SD; range -83 to +117 min).
