Text Readability Level Investigation about Biology Subjects-related Units in 'Science 7 Textbook'

This study investigates text readability level investigation about biology subjects-related units in 'Science 7 Textbook'. A document analysis method was used in this study based on a qualitative research approach. The textbook, which has been used since the 2019-2020 academic year, has been selected as the study material. In the textbook, a total of 15 texts were randomly determined from two units related to biology subjects, one for each of the learning outcomes specified in the 2018 Science Course Curriculum. In calculating the readability levels of the texts, the 'Ateşman Readability Formula' was used. The findings obtained as a result of the analysis showed that the overall readability levels of the texts in both units were in the 'medium difficulty' category. Furthermore, when the findings of each unit were examined on a subject basis, it was determined that the texts belonging to all of the topics included in both units (Cell and Divisions, Reproduction, Growth and Development in Living Beings) were found in the 'medium' category. These findings were interpreted as the science textbook prepared for the seventh grade for the student level in terms of readability

Evaluation of fluid overload markers in pediatric hemodialysis patients

Assessment of hydration status in children undergoing hemodialysis (HD) is crucial. This study aimed to identify the techniques that can be utilized to assess fluid overload in children with end-stage renal disease (ESRD) undergoing HD. The study included 9 patients aged >5 years and < 18 years who underwent 27 HD sessions and were followed up for ≥1 month. The median age of the patients was 16 years (IQR: 5-17.8 years) and the female/male ratio was 1.25:1. Symptoms of volume overload were clinically observed based on 5 (18.5%) of the 27 measurements. There was a significant positive linear correlation between fluid overload by weight and pre- and post-HD bioimpedance spectroscopy (BIS) measurements (OH) (r=0.95 [P=0.000]). There was a significant difference in median IVC diameter between pre-HD and after HD (P=0.029). The median pre-HD IVC collapsing index was 13.8% (IRQ: 4%-46%), versus 17.1% (IRQ: 4.5%-45%) after HD; the difference was significant (P=0.000). BIS is the most widely used body composition monitor for estimating fluid status in children undergoing HD. The present study investigated the sensitivity of markers of volume load in children on a routine HD program. The parameters that best indicate volume load are the differences between pre-HD and post-HD BIS measurements, physical examination findings, and heart rate measurements.

The Complication Profiles Following Surgical Dislocation of the Hip

The complication profiles of 45 hips of 44 cases that applied surgical dislocation by various indications in our institute between 2006-2013 were retrospectively reviewed. Our series consisted of 27 males and 17 females. Mean age of the cases was 31,9 (range, 11-58) years with mean follow-up time of 56,9 months (range, 13-106). The number of cases with detected complication was 27. Within our series 14 hips developed only 1 complication, 1 hip had 2, 10 hips had 3 and 2 hips had 4 individual complication profiles. Regarding Dindo-Clavien classifications of complication profiles, 17 hips were evaluated as Grade I (38%), 3 hips were Grade IIa (7%), 2 hips were Grade IIb (4%) and 5 hips were Grade III (11%). The presence of few number of or the absence of major complications in a surgical method does not make it absolutely safe. Surgical dislocations can be applied only when trochanteric complications are considered and the patients should be well informed by their orthopeadic surgeons

Analysis of complications following posterior vertebral column resection for the treatment of severe angular kyphosis greater than 100°

Objective: The aim of this study was to evaluate the complications, efficacy and safety of posterior vertebral column resection (PVCR) in severe angular kyphosis (SAK) greater than 100°. Methods: The medical records of 17 patients (mean age 17.9 (range, 9–27) years) with SAK who underwent PVCR, were reviewed. Mean follow-up period was 32.2 (range, 24–64) months. Diagnosis of the patients included congenital kyphosis in 11 patients, post-tuberculosis kyphosis in 3 patients and neurofibromatosis in 3 patients. The sagittal plane parameters (local kyphosis angle, lumbar lordosis, sagittal vertical axis, pelvic tilt, sacral slope and pelvic incidence) were measured in the preoperative and the early postoperative periods and during the last follow-up on the lateral radiographs. Results: The mean preoperative localized kyphosis angle was 121.8° (range, 101°–149°). The mean local kyphosis angle (LKA) was 71.5° at postoperatively evaluation (p < 0.05). Complications were detected in 12 patients (70.6%) with spinal shock in 4 patients, hemothorax in 3 patients, postoperative infection in 2 patients, dural laceration in 2 patients, neurological deficit in 2 patients (1 paraplegia and 1 root injury), the shifted cage in 2 patients and rod fracture in 2 patients. Neurological events occurred in six patients (35%) with temporary neurological deficit in 5 patients and permanent neurological deficit in 1 patient. Conclusion: PVCR is an efficient and a successful technique for the correction of SAK. However, it can lead to a large number of major complications in SAK greater than 100°. Level of evidence: Level IV, therapeutic study. Keywords: Posterior vertebral column resection, Severe angular kyphosis, Complication, Neurological deficit, Neuromonitorin

An investigation of the effects of total hip arthroplasty with femoral shortening in unilateral Crowe type-IV dysplastic hips on sagittal spinopelvic parameters

It has been reported that sagittal spinal alignment may become abnormal in patients with hip osteoarthritis. There is limited data in the literature on how spinopelvic parameters change after total hip arthroplasty (THA) with femoral shortening in unilateral Crowe type IV dysplastic hips. We aimed to investigate the effects of THA with femoral shortening in unilateral Crowe type IV dysplastic hips on sagittal spinopelvic parametres. Patients who underwent THA for Crowe type IV dysplastic hips at our institution between 2014-2019 were included in the study. Pre- and postsurgical standing anteroposterior and lateral spine X-Ray images of the each patient were uploaded to SURGIMAP© (Nemaris Inc.. USA) (https://www.surgimap.com/). The radiographic data of all patients were reviewed and measurements performed for each patient by two senior spinal surgeons. All of the parameters were retrieved from the SURGIMAP© measurement system. There were 18 patients aged 27-60 (mean, 45.5±7.9) years. The mean follow-up duration was 27.5 ± 8.9 (range, 13–42) months. There was no statistically difference between pre-and postoperative values of Sacral Slope (SS), Pelvic incidence (PI) Lumbar Lordosis (LL), PI-LL mismatch and Thoracic Kyphosis (TK), Global Tilt (GT), T1 Pelvic Angle (TPA), Cervical Lordosis (CL) and T1 slope (T1S). We also found no significant change between pre-and postsurgical values of global alignment and proportion (GAP) scores. The only significant change was in detected pre-and postsurgical values of PT, T1Spi, T9Spi ( p = 0.022, p = 0.035, and p = 0.033 respectively). THA with femoral shortening in unilateral Crowe type-IV dysplastic hips does not effect a change in sagittal spinopelvic parameters. Except for PT, T9SPi, and T1SPi do.

The effect of distraction-based growth friendly spinal instrumentation on growth in early-onset scoliosis

The benefits and drawbacks of growth friendly spinal instrumentation have been reported as a result of developments in the treatment of early-onset scoliosis. Seventeen patients who underwent growth friendly spinal instrumentation surgery with a minimum 2-year follow-up were included in the review. The mean number of lengthenings was 3, initial surgery age took place at 108.1 ± 30.2 months and follow-up at 40.6 ± 16.6 months. Spinal height (T1–S1 and T1–T12), space available for the lungs, major Cobb angle for scoliosis, maximum thoracic kyphosis, lumbar lordosis, shoulder and pelvic balance, and coronal and sagittal balance were assessed preoperatively and during the latest follow-up. Treatment with growth friendly spinal instrumentation provided an evident increase in spine height and space available for the lungs, and a significant decrease in scoliosis and thoracic kyphosis. In growth friendly spinal instrumentation treatment, the most commonly observed complications were proximal anchor problems (76.4%) and proximal junctional kyphosis (58.8%). In treatments using growing rods, excessive thoracic kyphosis correction should not be made to avoid proximal junctional kyphosis

THE PROPRIOCEPTION OF THE KNEE JOINT FOLLOWING TIBIA PLATEAU FRACTURES

Proprioception is a conscious and/or unconscious perception of position change in an extremity or joint in space. In our study our purpose was to evaluate whether the lower extremity proprioception in long term, is altered following tibia plateau fractures and to assess its relation with age and type of fracture.This retrospective study includes the evaluation of proprioception in 38 tibia plateau fracture patients (29 male, 9 female) of various types who were operated with open reduction and internal fixation (ORIF) technique in our clinic, by comparison of both operated knee and unaffected knee. The mean age of the patients were 38,8 (range, 20-60) and mean follow-up time was 56 months (range, 13-120 months). Proprioception measurements were assessed at 300 and 600 of knee flexion degrees both passively and actively.There were no significant difference between the operated knee and unaffected knee by mean absolute angular deviation values at passive (p=0,22) or active 600 (p=0,22). Accordingly passive (p=0,47) and active 300 (p=0,62) mean absolute angular deviation values showed no significant difference.Our study has indicated that proprioception at the operated extremity is not significantly different from the unaffected knee in tibia plateau fractures at long term follow-up.
