Effect of cervical and lumbosacral spina bifida cystica on volumes of intracranial structures in children.

PURPOSE: Spina bifida is a major disorder that occurs when the membranes of the spinal cord and medulla fail to close during the embryonic period and affects the individual for the rest of life. Some physical, mental, and social difficulties can be observed in the lives of children with spina bifida after surgery. The aim of this study is to determine what kind of volumetric changes occur in the brain when spina bifida occurs in different regions of the cord. METHODS: The volume of intracranial structures of 14 children aged 1 to 9 years (7 cervical, 7 lumbosacral) with different levels of spina bifida compared with vol2Brain. RESULTS: Spina bifida occurring in the cervical region was found to cause a greater volumetric reduction in subcortical structures, cortex and gyrus than spina bifida occurring in the lumbosacral region. CONCLUSION: We believe that our study will help clinicians involved in the management of this disorder.

Evaluation of the Relationship Between Preoperative and Postoperative Platelet Values and Amount of Blood Transfusion in Cases with Craniosinocytosis.

AIM: To demonstrate that decreased platelet count in patients with craniosynostosis increases the requirement for blood replacement, thus providing guidance to clinicians by revealing the time at which the platelet count decreases. Additionally, the relationship between the amount of blood transfusion and preoperative and postoperative platelet counts was evaluated. MATERIAL AND METHODS: This study included 38 patients with craniosynostosis who underwent surgery between July 2017 and March 2019. The patients exhibited no cranial pathologies except craniosynostosis. All surgeries were performed by a single surgeon. The demographic data, anesthesia and surgical durations, preoperative complete blood count and bleeding time, intraoperative blood transfusion amount, and postoperative complete blood count and total blood transfusion amount of the patients were recorded. RESULTS: The preoperative and postoperative changes and the timing of changes in hemoglobin and platelet counts, amount and timing of postoperative blood transfusion, and relationship between the amount and timing of blood replacement and preoperative and postoperative platelet counts were evaluated. The postoperative platelet counts tended to decrease after 12, 18, 24, and 36 hours (h), and began increasing after 48 h. Although decreased platelet count did not lead to platelet replacement, it influenced the erythrocyte replacement requirement in the postoperative period. CONCLUSION: Platelet count was associated with the amount of blood replacement. The platelet counts decreased within the first 48 h following surgery and tended to elevate thereafter; thus, clinicians should closely monitor these platelet counts within 48 h after surgery.

Evaluation of liver elasticity with shear-wave elastography in juvenile idiopathic arthritis patients receiving methotrexate.

BACKGROUND: Methotrexate (MTX) is the first-choice disease-modifying drug in juvenile idiopathic arthritis (JIA) treatment. Methotrexate is metabolized in the liver and can cause liver toxicity and fibrosis with long-term use. Ultrasound shear wave elastography (SWE) is a non-invasive method and can detect liver fibrosis by evaluating the liver elasticity. The aim of this study was to assess liver stiffness and detect if there is an increase in liver stiffness or fibrosis findings with the non-invasive SWE method in JIA patients under MTX treatment. METHOD: The study included 49 JIA patients under MTX treatment and 48 healthy controls, matched for age and sex with a body mass index below the 95th percentile. The demographic data and clinical characteristics of patients were obtained from medical records. Liver function tests were evaluated, and liver tissue stiffness measurements were performed with SWE. RESULTS: Of the 49 patients, 67.35% were girls and the mean age was 10.69 (±4.33) years. The duration of MTX treatment was 23.00 (1-80) months, and the cumulative dose of MTX was 1,280.867 mg (±934.2) in the patient group. There was no statistically significant difference in liver stiffness between patients receiving MTX and healthy controls (P = 0.313). There was no relationship between MTX duration, cumulative dose, route of administration, and liver stiffness. Only gamma glutamyl transferase values were weakly correlated with liver stiffness (P = 0.029). CONCLUSIONS: We did not detect an increase in liver tissue stiffness in JIA patients using methotrexate in comparison with controls.

Assessment of clinical, biochemical, and radiological outcomes following intra-articular injection of Wharton jelly-derived mesenchymal stromal cells in patients with knee osteoarthritis: A prospective clinical study.

The aim of the present study was to perform clinical, biochemical, and radiological evaluation of the efficacy of mesenchymal stem cells derived from Wharton jelly (WJ) present within the human umbilical cord in the treatment of knee osteoarthritis. Between 2018 and 2019, 10 patients with knee osteoarthritis for whom the conservative treatment was not beneficial were included in the study. Patients were clinically, radiologically, and biochemically evaluated before treatment initiation. Thereafter, the patients were intra-articularly injected using a solution containing 1 × 108 WJ-derived MSCs. Evaluations were performed on day 21 (V1) and 42 (V2) and month 3 (V3), 6 (V4), and 12 (V5) after the procedure. At 1-year post-injection, visual analogue scale, Western Ontario and McMaster Universities Osteoarthritis Index, and Lequesne scores of patients were lower than those observed during the initial evaluation, whereas the mean 36-Item Short Form Health Survey score was higher. Cartilage thicknesses were found to be increased in all regions except in the medial femur, medial posterior femur, lateral posterior femur, and lateral posterior tibia regions in magnetic resonance imaging. A significant increase was observed in tumor necrosis factor-alpha, interleukin-1ß, adiponectin, resistin, and interleukin-6 levels compared with pre-injection values. The leptin levels at 6-month and 1-year controls were lower than the pre-injection levels, and the decrease observed at 6 months was significant. In patients with knee osteoarthritis, intra-articular WJ-derived MSC injection causes significant pain reduction, satisfactory functional improvement, and increased patient satisfaction following a 1-year follow-up. These clinical improvements were supported by magnetic resonance images, along with changes in adiponectin and leptin levels in synovial fluid. Level of evidence: IV.

Circulating fibrocyte level in children with cystic fibrosis.

BACKGROUND: This study aimed to evaluate circulating fibrocyte levels in cystic fibrosis (CF) patients during stable and exacerbation periods of the condition. METHODS: The study group consisted of 39 patients diagnosed with CF and 20 healthy controls. Individuals included in the study were divided into three groups: CF, CF exacerbated, and a healthy control group. Their circulating fibrocyte levels were compared. Findings from a pulmonary function test and high-resolution computed tomography of the lung were evaluated and compared. RESULTS: The circulating fibrocyte count was found to be significantly higher in patients with CF compared with the exacerbated and control groups. No correlation was found between the forced expiratory volume in 1 s and forced vital capacity values in the pulmonary function test and the circulating fibrocyte count. The circulating fibrocyte count in patients (in the CF group) with positive findings in the high-resolution computed tomography was statistically significantly lower. CONCLUSIONS: The circulating fibrocyte level in the peripheral blood of the patients with CF was increased.

Encephalocraniocutaneous lipomatosis (Haberland syndrome) in a newborn baby: a case report with review of literature.

Encephalocraniocutaneous lipomatosis (ECCL) is an extremely uncommon, neurocutaneous disease, with a classical triad of ocular, skin lesions and central nervous system anomalies. We here report a case of ECCL in a newborn baby, characterized with naevus psiloliparus, choristoma, lipodermoids, cervical subcutaneous soft tissue mass, lowset ear, porencephalic cyst, polymicrogyria, arachnoid cyst, leptomeningeal angiomatosis and spinal lipomas. We here stress on the importance of early diagnosis to prevent misdiagnosis and employ a multidisciplinary approach in the management of these patients.

Relationship between Serum YKL-40 Level and Forearm Arterial Patency after Repair.

BACKGROUND: The study aimed to assess the effects of serum YKL-40 level on patency at the repair site in patients who underwent arterial repair at the level of the forearm. METHODS: The study included 58 subjects, including 29 patients (aged 18-50 years) who had ulnar or radial artery injury secondary to cut injury to wrist between June 2015 and November 2019 and no comorbid disease and 29 age- and sex-matched healthy controls. The vascular patency was assessed using Doppler sonography in patients who underwent arterial repair at the level of the forearm. The patients were defined as flow failure if the blood flow was ≤50%, and sufficient flow if the blood flow was >50% of those in the synonymous artery on the intact extremity. The YKL-40 level differences in the patient and control groups were compared to those in the sufficient and insufficient flow groups. RESULTS: The patients were stratified into 2 groups based on the presence of sufficient flow. The mean YKL level was 11.96 ± 8.87 in the sufficient flow groups, whereas it was 32.22 ± 15.43 in the insufficient flow groups (p= 0.038). Besides, it was found that each unit of increase in the YKL-40 level increased the likelihood of having flow failure by 1.128. CONCLUSION: Based on our results, it was observed that over-expression of the YKL-40 level has adverse effects on patency following arterial repair.

Is there an association of hematopoietic stem cell and endothelial progenitor cell markers with maturation in forearm arterial repair?

OBJECTIVES: This study aims to assess the effects of the hematopoietic stem cells and endothelial progenitor cells in peripheral blood and monocyte cluster of differentiation (CD) 34, CD133 and CD309 expression levels on maturation at the repair site in patients who underwent forearm arterial repair. PATIENTS AND METHODS: This prospective study included 30 patients (23 males, 7 females; mean age 28.9±1.8 years; range, 18 to 49 years) with a well-defined cut at the wrist due to a stabbing injury but no comorbid condition who presented to the emergency department of our hospital between November 2014 and November 2017. Vascular patency was assessed by Doppler sonography in patients who underwent forearm arterial repair via micro-vascular techniques. The relationships between patency and hematopoietic stem and endothelial progenitor cell markers such as CD34, CD133 and CD309 were assessed by flow cytometry. RESULTS: The patients were divided into two groups according to presence of sufficient flow in the arteries repaired. The mean CD34 expression level was 72.09±3.00 in the group with maturation whereas it was 54.64±7.34 in the group without maturation, indicating a statistically significant difference (p<0.05). In addition, the likelihood of sufficient flow was increased by 1.075 per one unit increase in CD34 level. Resistive index values were significantly lower in the group with maturation and CD34 level was predictive for maturation of arterial repair. CONCLUSION: In the present study, the findings demonstrated that high CD34 expression level has favorable effects on maturation after arterial repair.
