Clinical Consequences of Unreconstructed Pelvic Defect Caused by Osteosarcoma with Subsequent Progressive Scoliosis in a Pediatric Patient-Case Report.

Osteosarcoma is the most common primary malignant bone tumor in children and adolescents. The standard and most effective treatment is wide resection of the tumor combined with neoadjuvant chemotherapy. Adolescent idiopathic scoliosis (AIS) is a genetically determined three-dimensional spinal deformity, which occurs in teenage patients and is mostly progressive. The basic management strategy is surgical treatment when the curve exceeds 50 degrees. However, the indications are different in oncologic patients. The aim of this study was to describe a case of adolescent scoliosis with osteosarcoma of the pelvis. The authors conducted a scoping review using PubMed and Embase to analyze the state of knowledge. The presented paper is the first report of pelvis osteosarcoma coexisting with adolescent idiopathic scoliosis. Treatment for this complex case finished with very good results, with no recurrence observed during the nine-year follow-up.

Cryoanalgesia as the Essential Element of Enhanced Recovery after Surgery (ERAS) in Children Undergoing Thoracic Surgery-Scoping Review.

This article aims to present cryoanalgesia as an inventive strategy for pain alleviation among pediatric patients. It underlines the tremendous need to align pain management with the principles of the enhanced recovery after surgery (ERAS) approach. The aim of the study was to review the patient outcomes of nerve cryoanalgesia during surgery reported with regard to ERAS in the literature. The literature search was performed using PubMed and Embase to identify articles on the use of cryoanalgesia in children. It excluded editorials, reviews, meta-analyses, and non-English articles. The analysis focused on the study methods, data analysis, patient selection, and patient follow-up. This review includes a total of 25 articles. Three of the articles report the results of cryoanalgesia implemented in ERAS protocol in children. The research outcome indicates shortened hospital stay, potential reduction in opioid dosage, and significant progress in physical rehabilitation. This paper also describes the first intraoperative utilization of intercostal nerve cryoanalgesia during the Nuss procedure in Poland, highlighting its effectiveness in pain management. Adding the cryoanalgesia procedure to multimodal analgesia protocol may facilitate the implementation of the ERAS protocol in pediatric patients.

Benefits of the Erector Spinae Plane Block before Cryoanalgesia in Children Undergoing Surgery for Funnel Chest Deformity.

Thoracic surgery causes significant pain despite standard multimodal analgesia. Intraoperative cryoanalgesia may be a solution. The onset of the clinical effect of cryoanalgesia can take 12-36 h. The addition of a regional anaesthesia before the cryoanalgesia procedure can enable analgesic protection for the patient during this period. The main aim of the study was to evaluate the benefits of the erector spinae plane (ESP) block prior to Nuss surgery. The 'control' group consisted of 10 teenagers who underwent cryoablation together with intravenous multimodal analgesia according to the standard protocol. The 'intervention' group included 26 teenage patients who additionally received an erector spinae plane block before operation. Pain relief (p = 0.015), opioid use (p = 0.009), independent physical activity and rehabilitation (p = 0.020) were faster in the intervention group. No features of local anaesthetic drug toxicity or complications of the ESP block were observed. The bilateral ESP block together with intraoperative intercostal nerve cryoablation performed prior to Nuss correction of funnel chest were more effective in terms of pain control.

Novel Interdisciplinary Enhanced Recovery after Surgery Protocol Implementation in Paediatric Orthopaedics.

The enhanced recovery after surgery (ERAS) protocol is not routine management in paediatric orthopaedics. Cultural differences or assumptions about the financing of medical care in different countries encourage creative adaptation of general assumptions in local communities. The aim of this study was to compare the quality of the perioperative period before and after the introduction of an interdisciplinary protocol adopted to organisational conditions. A group of 4098 children were included in the "before-after" observational study. The data of 1553 patients (BEFORE group) were analysed in terms of compliance with the enhanced recovery after surgery protocol guidelines and the time and cost of hospitalisation over a 20-month period. A novel interdisciplinary protocol was developed, including an education and training app called BackOnFeet (BOF®), standardised hospital management, and the introduction of methods novel to Poland (intraoperative nerve cryoanalgesia in children). A further 2545 patients (AFTER group) were reassessed over a period of 20 months. It was found that the groups differed in hospitalisation time (p < 0.001), type of procedures, and percentage ratio of costs incurred to revenue generated. The usefulness of the BOF® app as an effective educational tool was demonstrated. The optimisation of perioperative management in paediatric orthopaedics based on novel tools and the interdisciplinary ERAS protocol is possible and brings tangible benefits in psychological, organisational, and financial terms.

Optimising Intraoperative Fluid Management in Patients Treated with Adolescent Idiopathic Scoliosis-A Novel Strategy for Improving Outcomes.

Scoliosis surgery is a challenge for the entire team in terms of safety, and its accomplishment requires the utilization of advanced monitoring technologies. A prospective, single centre, non-randomised controlled cohort study, was designed to assess the efficacy of protocolised intraoperative haemodynamic monitoring and goal-directed therapy in relation to patient outcomes following posterior fusion surgery for adolescent idiopathic scoliosis (AIS). The control group (n = 35, mean age: 15 years) received standard blood pressure management during the surgical procedure, whereas the intervention group (n = 35, mean age: 14 years) underwent minimally invasive haemodynamic monitoring. Arterial pulse contour analysis (APCO) devices were employed, along with goal-directed therapy protocol centered on achieving target mean arterial pressure and stroke volume. This was facilitated through the application of crystalloid boluses, ephedrine, and noradrenaline. The intervention group was subjected to a comprehensive protocol following Enhanced Recovery After Surgery (ERAS) principles. Remarkably, the intervention group exhibited notable advantages (p < 0.05), including reduced hospital stay durations (median 7 days vs. 10), shorter episodes of hypotension (mean arterial pressure < 60 mmHg-median 8 vs. 40 min), lesser declines in postoperative haemoglobin levels (-2.36 g/dl vs. -3.83 g/dl), and quicker extubation times. These compelling findings strongly imply that the integration of targeted interventions during the intraoperative care of AIS patients undergoing posterior fusion enhance a set of treatment outcomes.

The Impact of Intraoperative Haemodynamic Monitoring, Prediction of Hypotension and Goal-Directed Therapy on the Outcomes of Patients Treated with Posterior Fusion Due to Adolescent Idiopathic Scoliosis.

A prospective, single-centre, non-randomised, case-control study aimed to evaluate the effectiveness of intraoperative haemodynamic monitoring, prediction of hypotension and goal-directed therapy on the outcomes of patients undergoing posterior fusion for adolescent idiopathic scoliosis (AIS). The control group (n = 35, mean age: 15 years) received standard blood pressure control during surgery, while the intervention group (n = 24, mean age: 14 years) underwent minimally invasive haemodynamic monitoring and goal-directed therapy. The intervention group showed significantly shorter durations of hypotension (mean arterial pressure < 60 mmHg), reduced hospital stays and smaller decreases in post-surgery haemoglobin levels. Additionally, the intervention group experienced shorter times from the end of surgery to extubation. These findings suggest that incorporating targeted interventions during intraoperative care for AIS patients undergoing posterior fusion can lead to improved outcomes.

The Child's Age and the Size of the Curvature Do Not Affect the Accuracy of Screw Placement with the Free-Hand Technique in Spinal Deformities in Children and Adolescents.

BACKGROUND: The current method of treatment of spinal deformities would be almost impossible without pedicle screws (PS) placement. There are only a few studies evaluating the safety of PS placement and possible complications in children during growth. The present study was carried out to evaluate the safety and accuracy of PS placement in children with spinal deformities at any age using postoperative computed tomography (CT) scans. METHODS: 318 patients (34 males and 284 females) who underwent 6358 PS fixations for pediatric spinal deformities were enrolled in this multi-center study. The patients were divided into three age groups: less than 10 years old, 11-13 years old, and 14-18 years old. These patients underwent postoperative CT scans and were analyzed for pedicle screw malposition (anterior, superior, inferior, medial, and lateral breaches). RESULTS: The breach rate was 5.92% for all pedicles. There were 1.47% lateral and 3.12% medial breaches for all pedicles with tapping canals, and 2.66% lateral and 3.84% medial breaches for all pedicles without a tapping canal for the screw. Of the 6358 screws placed in the thoracic, lumbar, and sacral spine, 98% of the screws were accurately placed (grade 0, 1, and juxta pedicular). A total of 56 screws (0.88%) breached more than 4 mm (grade 3), and 17 (0.26%) screws were replaced. No new and permanent neurological, vascular, or visceral complications were encountered. CONCLUSIONS: The free-hand technique for pedicle screw placement in the acceptable and safety zone in pedicles and vertebral bodies was 98%. No complications associated with screw insertion in growth were noted. The free-hand technique for pedicle screw placement can be safely used in patients at any age. The screw accuracy does not depend on the child's age nor the size of the deformity curve. Segmental instrumentation with posterior fixation in children with spinal deformities can be performed with a very low complication rate. Navigation of the robot is only an auxiliary tool in the hands of the surgeons, and the result of the work ultimately depends on the surgeons.

Clinical Relevance of Gut Microbiota Alterations under the Influence of Selected Drugs-Updated Review.

As pharmacology and science progress, we discover new generations of medicines. This relationship is a response to the increasing demand for medicaments and is powered by progress in medicine and research about the respective entities. However, we have questions about the efficiency of pharmacotherapy in individual groups of patients. The effectiveness of therapy is controlled by many variables, such as genetic predisposition, age, sex and diet. Therefore, we must also pay attention to the microbiota, which fulfill a lot of functions in the human body. Drugs used in psychiatry, gastroenterology, diabetology and other fields of medicine have been demonstrated to possess much potential to change the composition and probably the function of the intestinal microbiota, which consequently creates long-term risks of developing chronic diseases. The article describes the amazing interactions between gut microbes and drugs currently used in healthcare.

Intercostal nerve cryoanalgesia in the treatment of pain in patients operated on by the modified Nuss method with the BackOnFeet application-a new strategy to improve outcomes.

Introduction: The surgical Nuss correction of the funnel chest deformity is a painful procedure without an established consensus of pain relief methods. High doses and long duration of opioids requirements impedes the ERAS protocol introduction. The aim of this study was to evaluate the effectiveness of intraoperative intercostal nerve cryolysis in terms of pain management in relation to the routinely used multimodal analgesia in Poland. We also assessed the impact of using the proprietary "BackOnFeet" application on the quality of life of patients after surgery in relation to the ERAS protocol. Methods: The prospective, single-centre, non-randomised, before-after pilot study was conducted. Inclusion criteria were: funnel-shaped chest deformity, age range 11-18 years, first chest wall operation, agreement for the cryolysis and regional analgesia, no history of chronic painkillers use. The results of the "control group" (multimodal analgesia with regional analgesia commonly performed in Poland) were assessed. The interdisciplinary perioperative protocol with the "BackOnFeet" application and intraoperative intercostal nerve cryoanalgesia were introduced to the "intervention group". Results: Eighteen children were treated with standard protocol typical for Polish management and matched to eighteen patients who received cryoanalgesia and the "BackOnFeet" application access "intervention group". We noticed lower NRS points in first 24 h (p = 0.0048), shortening of time of opioid use (p = 0.0002), hospitalisation time (p = 0,01), improved quality of postoperative rehabilitation (p < 0.0001) and quality of life (p < 0.0001) among the "intervention group". Conclusions: Intraoperative intercostal nerves cryolysis performed during the minimally invasive Nuss correction of funnel deformation in combination with bilateral is more effective in terms of acute pain management in relation to the routinely used multimodal analgesia in Poland, allowing for the shortening of time of opioid use, hospitalisation time, improved quality of postoperative rehabilitation and enabled ERAS protocol introduction. The use of the proprietary "BackOnFeet" application has a positive effect on the quality of life of patients after surgery.

The use of the Ilizarov technique in the treatment of upper limb deformity in patients with Ollier's disease.

Between 1997 and 2001 three children with Ollier's disease underwent treatment of five upper limb segments using the Ilizarov technique. Average length discrepancy was 8.4 cm in the arm and 4.5 cm in the forearm, but coexisting large angular deformities were the major problem in all the children. Full correction of the axial deviations was achieved in all children. Restoration of length was achieved in all arms, but residual forearm length discrepancy persisted. In four segments conversion of the abnormal cartilage into normal regenerate was observed on radiograms. The problems, obstacles, and complications are similar to those met in more usual lengthening procedures. The Ilizarov technique should be the treatment of choice in restoring the correct axis and length of a limb in patients with Ollier's disease.

[Treatment results of triplanar correction of idiopathic scoliosis in relation to curve pattern and degree of scoliosis]. / Wyniki leczenia skoliozy idiopatycznej metoda trojplaszczyznowej korekcji w zaleznosci od typu i wielkosci znieksztalcenia.

Background. The King classification enables the surgeon to assess the curve pattern of scoliosis which determines the choice of operative technique as well as the extent of spinal fusion. The final outcome of operative treatment depends on the curve pattern and the degree of scoliosis. Material and methods. The aim of the study was to assess the relation between the correction of the deformity and the curve pattern. In this retrospective study, 97 patients were included who had undergone scoliosis surgery between 1999 and 2001, and for whom the follow-up period was at least 36 months. 12 patients were classified as type I according to the King classification, 26 as type II, 49 as type III, and 5 each as type IV and V. The mean Cobb angle in the whole group was 58 degrees in the thoracic region and 38 degrees in the lumbar region, while in the sagittal plane there was kyphosis of the thoraco-lumbar region of 3 degrees . Results. Postoperative values were as follows: thoracic region - 30.2 degrees , lumbar region - 27.6 degrees and thoraco-lumbar region - lordosis of 4 degrees . Conclusions. The Cotrel-Dubousset method makes it possible to achieve an average correction of 65% of the original deformity, the best result being achieved for type IV and V. Operative treatment should be applied to patients with scoliosis of an angle below 60 degrees , which enables compensation of trunk transposition.
