Introduction: The subject of the study is analyzing of the temperature distribution on the lower limbs in patients with discopathy of the lumbosacral spine requiring surgery. Aim: The answer to the question whether surgical treatment reduces temperature differences on the lower limbs of patients undergoing surgery. Material and methods: Thermograms of the lower limbs were performed before and on the second day after microdiscectomy or microdiscectomy with posterior lumbar interbody fusion. The study group consisted of 37 patients of the Neurosurgery Department, while the control group consisted of 18 healthy people. Comparative analyzes of temperatures on the lower limb with pain with the temperatures on the lower healthy limb in the same patient indicate significant statistical differences in temperature distribution. Based on the thermograms, two region of interest’s (ROI) of the same area were determined on the thigh and the lower leg. The maximum, minimum and average temperatures were determined for those areas. Results and discussion: Comparative analyzes showed statistically significant differences for both areas and all temperatures between healthy and affected limbs in the group of patients before surgery. In turn, after surgery, no statistically significant differences were observed between the respective limb temperatures for both ROI areas. The analysis of the temperature parameters determined for analogous ROIs in the control group did not show statistically significant differences for all measured temperatures. Conclusions: After selective surgical treatment of lumbar discopathy by microdiscectomy previous significantly statistical temperature differences between the lower limbs in analogical ROIs in those patients decreased to not statistically significant differences.

ABSTRACT Objectives: To compare the outcomes of surgical treatment with lumbar fixation using nitinol rods without fusion and with standard lumbar fixation with titanium rods and interbody fusion. Methods: Treatment results of 70 patients with degenerative lumbar scoliosis aged 40 to 82 were analyzed. In all cases pedicle screws and nitinol rods with a diameter of 5.5 mm were used. Thirty patients underwent fixation at L1-S1 and 40 patients underwent fixation at L1-L5. Spinal fusion was not performed. All patients had radiography, CT and MRI performed. The results were assessed according to the Oswestry scale, SRS 22, SF 36 and VAS. The minimum follow-up period for all patients was 2.5 years. For the control group, consisting of 72 patients, pedicle fixation with titanium rods and interbody fusion in the lumbosacral region were performed. Results: The average level of deformity correction equaled 25° (10° - 38°). The analysis of X-ray and CT-scans revealed a single patient with implant instability, two patients with bone resorption around the screws and one patient with rod fractures. Functional radiography 2.5 years after surgery showed an average mobility of the lumbar spine of 21° (15° - 30°). There were no problems at the adjacent levels. Conclusions: The use of nitinol rods in spinal deformity surgery is promising. This technology is an alternative to rigid fixation. Continued gathering of clinical data and its further evaluation is necessary.

The Relationship

OBJECTIVE The importance of spinopelvic balance and its implications for clinical outcomes after spinal arthrodesis has been reported in recent studies. However, little is known about the relationship between adjacent-segment disease (ASD) after lumbar arthrodesis and spinopelvic alignment. The purpose of this study was to clarify the relationship between spinopelvic radiographic parameters and symptomatic ASD after L4–5 single-level posterior lumbar interbody fusion (PLIF). METHODS This was a retrospective 1:5 matched case-control study. Twenty patients who had undergone revision surgery for symptomatic ASD after L4–5 PLIF and had standing radiographs of the whole spine before primary and revision surgeries were enrolled from 2005 to 2012. As a control group, 100 age-, sex-, and pathology-matched patients who had undergone L4–5 PLIF during the same period, had no signs of symptomatic ASD for more than 3 years, and had whole-spine radiographs at preoperation and last follow-up were selected. Mean age at the time of primary surgery was 68.9 years in the ASD group and 66.7 years in the control group. Several radiographic spinopelvic parameters were measured as follows: sagittal vertical axis (SVA), thoracic kyphosis (TK), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), lumbar lordosis (LL), and segmental lordosis at L4–5 (SL) in the sagittal view, and C7–central sacral vertical line (C7-CSVL) in the coronal view. Radiological parameters were compared between the groups. RESULTS No significant change was found between pre- and postoperative radiographic parameters in each group. In terms of preoperative radiographic parameters, the ASD group had significantly lower LL (40.7° vs 47.2°, p < 0.01) and significantly higher PT (27° vs 22.9°, p < 0.05) than the control group. SVA ≥ 50 mm was observed in 10 of 20 patients (50%) in the ASD group and in 21 of 100 patients (21%, p < 0.01) in the control group. PI-LL ≥ 10° was noted in 15 of 20 patients (75%) in the ASD group and in 40 of 100 patients (40%, p < 0.01) in the control group on preoperative radiographs. Postoperatively, the ASD group had significantly lower TK (22.5° vs 30.9°, p < 0.01) and lower LL (39.3° vs 48.1°, p < 0.05) than the control group had. PI-LL ≥ 10° was seen in 15 of 20 patients (75%) in the ASD group and in 43 of 100 patients (43%, p < 0.01) in the control group. CONCLUSIONS Preoperative global sagittal imbalance (SVA > 50 mm and higher PT), pre- and postoperative lower LL, and PI-LL mismatch were significantly associated with ASD. Therefore, even with a single-level PLIF, appropriate SL and LL should be obtained at surgery to improve spinopelvic sagittal imbalance. The results also suggest that the achievement of the appropriate LL and PI-LL prevents ASD after L4–5 PLIF.

OBJECTIVE Tranexamic acid (TXA), a synthetic antifibrinolytic drug, has been reported to reduce blood loss in orthopedic surgery, but there have been few reports of its use in spine surgery. Previous studies included limitations in terms of different TXA dose regimens, different levels and numbers of fused segments, and different surgical techniques. Therefore, the authors decided to strictly limit TXA dose regimens, surgical techniques, and fused segments in this study. There have been no reports of using TXA for prevention of intraoperative and postoperative blood loss in posterior lumbar interbody fusion (PLIF). The purpose of the study was to evaluate the efficacy of high-dose TXA in reducing blood loss and its safety during single-level PLIF. METHODS The study was a nonrandomized, case-controlled trial. Sixty consecutive patients underwent single-level PLIF at a single institution. The first 30 patients did not receive TXA. The next 30 patients received 2000 mg of intravenous TXA 15 minutes before the skin incision was performed and received the same dose again 16 hours after the surgery. Intra- and postoperative blood loss was compared between the groups. RESULTS There were no statistically significant differences in preoperative parameters of age, sex, body mass index, preoperative diagnosis, or operating time. The TXA group experienced significantly less intraoperative blood loss (mean 253 ml) compared with the control group (mean 415 ml; p < 0.01). The TXA group also had significantly less postoperative blood loss over 40 hours (mean 321 ml) compared with the control group (mean 668 ml; p < 0.01). Total blood loss in the TXA group (mean 574 ml) was significantly lower than in the control group (mean 1080 ml; p < 0.01). From 2 hours to 40 hours, postoperative blood loss in the TXA group was consistently significantly lower. There were no perioperative complications, including thromboembolic events. CONCLUSIONS High-dose TXA significantly reduced both intra- and postoperative blood loss without causing any complications during or after single-level PLIF.

It has often been argued that the teaching of L2 articulatory settings (AS) will improve learners' L2 pronunciation. However, although many impressionistic accounts have been written on the subject, only few empirical studies have been conducted to test these assumptions. This article reports on a study set out to test the effectiveness of teaching AS differences to Dutch secondary school pupils in order to improve their pronunciation of English. Four AS lessons were given to a group of secondary school pupils, while a control group received standard pronunciation lessons concentrating on segmental differences. The pupils were recorded while doing a picture description task both before and after instruction. Native speaker judges then assessed their English pronunciation proficiency. Although no significant differences were found between pre and post instruction pronunciation proficiency in both groups as a whole, there were a number of pupils in both groups that did improve their pronunciation. These results might be explained by Dynamic Systems Theory.

The purpose of this study is to analyze the effects of flipped learning on students' academic achievements in the subject of science at Bilim Innovation Lyceums (BIL) in Kazakhstan. For this purpose, pre and post surveys were conducted on 168 students who were divided into two groups; the experimental group consisting of 84 students who took part in flipped learning classes for seven weeks and the control group consisting of 84 students who experienced the traditional method of classroom instruction at the same period. To achieve the objectives of the study, a final placement test score was used before and after the introduction of the flipped classroom model. The results of the study are summarized as follows. There were a significant difference between the two groups in terms of academic achievement when it measured by test scores before and after the concerned semester. On the basis of these findings, several suggestions were made for the schools to utilize innovative instructional methods including flipped learning for sustainable education in the future.

OBJECTIVE: To correlate the levels of interleukins 1 β, 3, 4, and 5 before and after surgery and compare the levels between patients with and without recurrence of nasal polyposis. STUDY DESIGN AND SETTING: Thirty-nine patients with NP were selected, 13 of them allergic and 26 nonallergic. A control group of 11 individuals was also studied. The concentrations of interleukins were measured by enzyme-linked immunosorbent assay. RESULTS: There was a higher incidence of NP after the fourth decade of life and among men. The clinical symptoms were similar in both groups of patients with nasal polyposis and characterized by nasal obstruction and anosmia. A significant reduction of all interleukins studied was observed after surgical treatment. CONCLUSION: Levels of interleukins 1β, 3, 4, and 5 were significantly reduced after surgery and the levels of interleukins 1β and 5 were significantly lower in patients without recurrence of nasal polyposis after surgery when compared to those with recurrence.

The aim of the research was to identify the pattern of psycho - physiological response to emotional stimulation in adults with chronic stuttering. The need to tell a lie functioned as emotional stimulation. Reaction to the stimulus was defined as the change of electrodermal activity (EDA), heart rate (HR), thoracic breathing (TB), diaphragmatic breathing (DB) and respiratory rate (RR) observed 10 seconds before and after the emotional stimulation. Reactions were recorded using Professional Computer Polygraph PIK-02 manufactured by Areopag-Center. The subject group included 68 persons with chronic stuttering (PWS) (24 women and 44 men) as well as 62 healthy nonstuttering persons (PWNS) (18 women and 44 men). Adult patients with chronic stuttering were observed to increase the amplitude and reaction field as well as reduce the EDA latency. The researchers also noticed both increased HR and the range of its changes. Respiratory reactions included a lower amplitude of TB, higher increase and major changes within DB as well as minor changes in RR. Adult patients with chronic stuttering display a unique pattern of psychophysiological response to emotional stimulation, which is different from the one found in the control group.

Study Design: A retrospective case-control study. Objectives: The usefulness of a drain in spinal surgery has always been controversial. The purposes of this study were to determine the incidence of hematoma-related complications after posterior lumbar interbody fusion (PLIF) without a drain and to evaluate its usefulness. Methods: We included 347 consecutive patients with degenerative lumbar disease who underwent single- or double-level PLIF. The participants were divided into 2 groups by the use of a drain or not; drain group and no-drain group. Results: In 165 cases of PLIF without drain, there was neither a newly developed neurological deficit due to hematoma nor reoperation for hematoma evacuation. In the no-drain group, there were 5 (3.0%) patients who suffered from surgical site infection (SSI), all superficial, and 17 (10.3%) patients who complained of postoperative transient recurred leg pain, all treated conservatively. Days from surgery to ambulation and length of hospital stay (LOS) of the no-drain group were faster than those of the drain group ( P < 0.001). In a multiple regression analysis, a drain insertion was found to have a significant effect on the delayed ambulation and increased LOS. No significant differences existed between the 2 groups in additional surgery for hematoma evacuation, or SSI. Conclusions: No hematoma-related neurological deficits or reoperations caused by epidural hematoma and SSI were observed in the no-drain group. The no-drain group did not show significantly more frequent postoperative complications than the drain use group, hence the routine insertion of a drain following PLIF should be reconsidered carefully.

Abstract Background: Wound-related complications are an inevitable issue faced by spinal surgeons. Negative pressure drainage remains the most commonly used method to prevent postoperative hematoma and related complications. This prospective, randomized, controlled study was conducted to evaluate the efficacy of compression therapy following posterior lumbar interbody fusion, with emphasis on pain, anemia, and inflammation. Methods: Sixty consecutive patients who have undergone posterior lumbar interbody fusion in the age range 43–78 years, with an average age of 59 years, were selected and randomly assigned into two groups. Factors, such as drainage volume, visual analog scale (VAS) pain score for back pain, white blood cell (WBC) count , red blood cell (RBC) count, hemoglobin (Hb) levels, erythrocyte sedimentation rate(ESR), and C-reactive protein (CRP) levels assessed on the 1st, 3rd, and 10th days postoperatively, were compared between the two groups. Results: The average follow-up was 6 months, ranging from 3 to 11 months. Drainage volume, VAS score, and CRP levels on the 10th day after the surgery were found to be significantly lower in the treatment group than in the control group. RBC count and Hb levels on the 3rd and 10th postoperative days were observed to be significantly higher in the treatment group than in the control group ( P <0.05). During discharge, the wounds of the patients of the both groups had healed and neither showed any symptoms of infection, hematoma, or necrosis. Conclusion: Compression therapy relieves pain, alleviates anemia, and the inflammatory response following posterior lumbar interbody fusion.
