Lateralizing calcaneal osteotomy performed with a percutaneous burr results in a significantly lower increase in tarsal tunnel pressure.

PURPOSE: Tarsal tunnel syndrome is well documented following lateralizing calcaneal osteotomy to manage varus hindfoot deformity. Traditionally, calcaneal osteotomy is performed with an oscillating saw. No studies have investigated the effect of alternative surgical techniques on postoperative tarsal tunnel pressure. The purpose of this study was to investigate the difference in tarsal tunnel pressures following lateralizing calcaneal osteotomy performed using a high-torque, low-speed "minimally invasive surgery" (MIS) Shannon burr versus an oscillating saw. METHODS: Lateralizing calcaneal osteotomy was performed on 10 below-knee cadaveric specimens. This was conducted on 5 specimens each using an oscillating saw (Saw group) or MIS burr (Burr group). The calcaneal tuberosity was translated 1 cm laterally and transfixed using 2 Kirschner wires. Tarsal tunnel pressure was measured before and after osteotomy via ultrasound-guided percutaneous needle barometer. Mean pre/post-osteotomy pressures were compared between groups. Differences were analyzed using Student's t test. RESULTS: The mean pre-procedure tarsal tunnel pressure was 25.8 ± 5.1 mm Hg in the Saw group and 26.4 ± 4.3 mm Hg in the Burr group (p = 0.85). The mean post-procedure pressure was 63.4 ± 5.1 in the Saw group and 47.8 ± 4.3 in the Burr group (p = 0.01). Change in tarsal tunnel pressure was significantly lower in the Burr group (21.4 ± 4.5) compared to the Saw group (37.6 ± 12.5) (p = 0.03). The increase in tarsal tunnel pressure was 43% lower in the Burr group. CONCLUSION: In this cadaveric study, tarsal tunnel pressure increase after lateralizing calcaneal osteotomy was significantly lower when using a burr versus a saw. This is likely because the increased width ("kerf") of the 3 mm MIS burr, compared to the submillimeter saw blade width, causes calcaneal shortening. Given the smaller increase in tarsal tunnel pressure, using the MIS burr for lateralizing calcaneal osteotomy may decrease the risk of postoperative tarsal tunnel syndrome. Future research in vivo should explore this.

Adjuvant Radiofrequency Ablation Along With Stenting Versus Stenting Alone for Biliary Tree Drainage in Patients With Malignant Biliary Strictures: A Systemic Review and Meta-analysis.

OBJECTIVE: This metanalysis aims to assess the efficacy and safety of biliary stenting along with radiofrequency ablation compared with stents alone to treat malignant biliary obstruction (MBO) due to extrahepatic biliary strictures secondary to cholangiocarcinoma, pancreatic cancer, and metastatic cancer. METHODS: A systemic search of major databases through April 2022 was done. All original studies were included comparing radiofrequency ablation with stenting versus stenting alone for treating malignant biliary strictures. The primary outcomes of interest were the difference in the mean stent patency and overall survival (OS) days between the 2 groups. The secondary outcome was to compare the adverse events of the 2 groups. The mean difference in the stent patency and OS days was pooled by using a random-effect model. We calculated the odds ratio to compare the adverse events between the 2 groups. RESULTS: A total of 13 studies with 1339 patients were identified. The pooled weighted mean difference in stent patency was 43.50 days (95% CI, 25.60-61.41), favoring the RFA plus stenting. Moreover, the pooled weighted mean difference in OS was 90.53 days (95% CI, 49.00-132.07), showing improved survival in the RFA group. Our analysis showed no statistically significant difference in adverse events between the 2 groups OR 1.13 (95% CI, 0.90-1.42). CONCLUSION: Our analysis showed that RFA, along with stent, is safe and is associated with improved stent patency and overall patient survival in malignant biliary strictures. More robust prospective studies should assess this association further.

International Consensus Recommendations for Safe Use of LAMS for On- and Off-Label Indications Using a Modified Delphi Process.

INTRODUCTION: The study aimed to develop international consensus recommendations on the safe use of lumen-apposing metal stents (LAMSs) for on- and off-label indications. METHODS: Based on the available literature, statements were formulated and grouped into the following categories: general safety measures, peripancreatic fluid collections, endoscopic ultrasound (EUS)-biliary drainage, EUS-gallbladder drainage, EUS-gastroenterostomy, and gastric access temporary for endoscopy. The evidence level of each statement was determined using the Grading of Recommendations Assessment, Development, and Evaluation methodology.International LAMS experts were invited to participate in a modified Delphi process. When no 80% consensus was reached, the statement was modified based on expert feedback. Statements were rejected if no consensus was reached after the third Delphi round. RESULTS: Fifty-six (93.3%) of 60 formulated statements were accepted, of which 35 (58.3%) in the first round. Consensus was reached on the optimal learning path, preprocedural imaging, the need for airway protection and essential safety measures during the procedure, such as the use of Doppler, and measurement of the distance between the gastrointestinal lumen and the target structure. Specific consensus recommendations were generated for the different LAMS indications, covering, among others, careful patient selection, the preferred size of the LAMS, the need for antibiotics, the preferred anatomic location of the LAMS, the need for coaxial pigtail placement, and the appropriate management of LAMS-related adverse events. DISCUSSION: Through a modified international Delphi process, we developed general and indication-specific experience- and evidence-based recommendations on the safe use of LAMS.

Dedicated Early Morning Orthopaedic Trauma Operating Room Is Associated With Shorter Time to Surgery and Decreased Length of Hospital Stay for Children Undergoing Surgical Treatment of Supracondylar Humerus Fractures: A Retrospective Cohort Study.

INTRODUCTION: The purpose of this study was to investigate whether the use of a dedicated early morning orthopaedic trauma operating room (OR) resulted in shorter wait times, decreased surgical times, decreased length of stay (LOS), and decreased complications in children treated with urgent surgical intervention for supracondylar humerus fractures. METHODS: This retrospective comparative cohort study at a level I pediatric trauma center included patients younger than 12 years with supracondylar humerus fractures urgently treated with closed or open reduction and percutaneous pinning. Index surgical cases from April 28, 2013, to February 26, 2020, were included. Patients with prior humerus fracture, concomitant injuries, open fracture, pulseless supracondylar fracture, or missing data were excluded. Patients were analyzed based on the type of OR: dedicated early morning orthopaedic trauma OR or typical daytime orthopaedic OR. The primary outcome was time from presentation to surgery. Secondary outcomes included surgical time, complications, and LOS. RESULTS: A total of 401 patients with a mean age of 5 ± 2 (range: 1 to 11) years and a mean follow-up of 2.0 ± 2.1 (range: 0.5 to 25.0) months were included, of whom 137 patients (34%) underwent surgery in the early morning dedicated orthopaedic trauma OR. The dedicated early morning orthopaedic OR group had significantly less time from presentation to surgery (7.5 versus 9.4 hours; P = 0.0002) and shorter LOS (21.0 versus 24.0 hours; P = 0.004) compared with children treated in the typical daytime orthopaedic OR. Surgical time (31.1 versus 32.6 minutes; P = 0.40) and complication rates (5.8% versus 4.9%; P = 0.65) were similar between the groups. No revision surgery was required in either group. DISCUSSION: Surgical wait times were diminished with use of the dedicated early morning OR, as was LOS. Surgical times and complication rates were similar between groups. Institutions may consider adopting a dedicated early morning orthopaedic trauma OR to improve surgical wait times and decrease LOS. LEVEL OF EVIDENCE: III.

Safety and adverse events of EUS-guided gallbladder drainage using lumen-apposing metal stents and percutaneous cholecystostomy tubes: a systematic review and meta-analysis.

BACKGROUND AND AIMS: EUS-guided gallbladder drainage using lumen-apposing metal stents (EUS-GBD-LAMSs) and percutaneous cholecystostomy for gallbladder drainage (PTGBD) are the alternative treatment modalities in high-risk surgical patients with acute cholecystitis (AC). The aim of this study was to compare the safety of these procedures for AC in surgically suboptimal candidates. METHODS: Six studies compared the 2 groups' early, delayed, and overall adverse events; they also compared length of hospital stay, re-interventions, and re-admissions rate. A random effect model calculated odds ratios (ORs) with a 95% confidence interval (CI). RESULTS: The 2 groups had similar early adverse events; however, EUS-GBD-LAMS was associated with a lower rate of delayed (OR, .21; 95% CI, .07-.61; P ≤ .01) and overall (OR, .43; 95% CI, .30-.61; P ≤ .01) adverse events. Patients with EUS-GBD-LAMSs had a shorter hospital stay than PTGBD. CONCLUSIONS: EUS-GBD-LAMS is a safer option than PTGBD and is associated with a shorter hospital stay in nonsurgical candidates with AC.

Deformity angular ratio is associated with neuromonitoring changes without a vertebral column resection: spinal deformity is more influential than type of surgery.

PURPOSE: The purpose of this study is to investigate the effect of the deformity angular ratio (DAR) on intra-operative neuromonitoring (IONM) signal changes during posterior spinal fusion (PSF) without vertebral column resection (VCR). METHODS: Retrospective review of severe pediatric spinal deformity patients treated with PSF without VCR or three-column osteotomy from 2008 to 2018. Exclusion criteria were prior instrumentation, lack of IONM, and incomplete radiographic data. Coronal DAR (C-DAR), sagittal DAR (S-DAR), and total DAR (T-DAR) were calculated and compared between patients with IONM signal loss and those without. RESULTS: Two hundred and fifty-three patients met inclusion criteria. Forty-seven of two hundred and fifty-three (19%) patients had IONM signal loss. Intra-operative wake-up test was performed in seven cases; three of seven (43%) had a neurological deficit on wake-up test. All neurological deficits resolved at a mean of 41 days postop. IONM loss was associated with increased kyphosis (p = 0.003) and was not associated with Cobb angle (p = 0.16). S-DAR (p = 0.03) and T-DAR (p = 0.005) were associated with IONM signal loss but C-DAR was not (p = 0.06). Increased incidence of IONM signal loss was seen with S-DAR > 7 (p = 0.02) or T-DAR > 27 (p = 0.02). Twenty-four of ninety-two (26%) patients with S-DAR > 7 had IONM signal loss compared to twenty-three of one hundred and sixty-one (14%) with S-DAR ≤ 7 (OR, 2.1; 95% CI, 1.1-4.0). Seven of sixteen (44%) patients with T-DAR > 27 had signal loss compared to forty of two hundred and thirty-seven (17%) patients with T-DAR ≤ 27 (OR, 3.8; 95% CI, 1.3-10.9). CONCLUSION: Patients with S-DAR > 7 or T-DAR > 27 have a higher risk of IONM loss during pediatric PSF even in the absence of a VCR or three-column osteotomies.

Modernizing Our Understanding of Total Hip Arthroplasty in the Pediatric and Young Adult Patient: A Single-center Experience.

INTRODUCTION: Pediatric hip disorders represent a broad range of pathology and remain a significant source of morbidity for children and young adults. Surgical intervention is often required for joint preservation, but when salvage is not possible, joint replacement may be indicated to eliminate pain and preserve function. Although there have been significant updates in the management of both pediatric hip disease and the field of total hip arthroplasty (THA), there is a paucity of literature reflecting advancements in the area of pediatric and young adult (PYA) arthroplasty. No study has investigated the impact of approach on outcomes after PYA THA. The purpose of this study is to describe the indications, techniques, and early outcomes of THA in the PYA population in a modern practice setting. METHODS: We performed a retrospective descriptive analysis of all patients undergoing primary THA performed at a tertiary care children's hospital from 2004 to 2019. Ninety-three hips in 76 patients were evaluated. Demographics, intraoperative variables, postoperative pain and function ratings, and complication and revision rates were collected. RESULTS: Eighty-five hips in 69 patients were included. Patients were aged 12 to 23 years old, with males and females represented equally (33 vs. 36, respectively). The most common cause of hip pain was avascular necrosis (AVN, 56/85, 66%), most commonly due to slipped capital femoral epiphysis (13/56, 23%) idiopathic AVN (12/56, 21%), and chemotherapy (12/56, 21%). Half of all hips had been previously operated before THA (43/85). Thirty-six procedures were performed via the posterolateral approach (36/85, 42%), 33 were performed via direct anterior approach (33/85, 39%), and 16 were performed via the lateral approach (LAT, 16/85, 19%). At final follow-up, 98% (83/85) of patients had complete resolution of pain, 82% (70/85) had no notable limp, and 95% (81/85) had returned to all activities. There were 6 complications and 1 early revision. Average Hip disability and Osteoarthritis Outcomes Score for Joint Replacement scores increased by 37 points from 56 to 93. The overall revision-free survival rate for PYA THA was 98.8% (at average 19-mo follow-up). CONCLUSIONS: Modern PYA THA is dissimilar in indications and surgical techniques to historic cohorts, and conclusions from prior studies should not be generalized to modern practice. In our practice, PYA patients most commonly carry a diagnosis of AVN, and THA can be performed with modern cementless fixation with large cup and head sizes and ceramic-on-cross-linked polyethylene bearings utilizing any approach. Further study is required to better characterize middle-term and long-term results and patient-reported outcomes. LEVEL OF EVIDENCE: Therapeutic Level IV-retrospective case series.

Genome Editing and Fatty Liver.

Fatty liver disease is characterized as nonalcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD). Fatty liver disease is one of the most common causes of chronic liver disease worldwide among adults and children. It is characterized by excessive fat accumulation in the liver cells. It has a genetically heterogenous background with complex pathogenesis and progressions and is accompanied by significant morbidity, mortality, and healthcare costs. NAFLD's risk factors include metabolic syndrome, abdominal obesity, type 2 diabetes, and atherogenic dyslipidemia. ALD is associated with the excessive consumption of alcohol. Here, we describe the functions of various proteins encoded by gene variants contributing to the pathogenesis of nonalcoholic fatty liver disease and alcoholic fatty liver disease. Advancements in genome engineering technology have generated various in vivo and in vitro fatty liver disease models reflecting the genetic abnormalities contributing toward fatty liver disease. We will discuss currently developed different ALD and NAFLD models using the clustered regularly interspaced short palindromic repeats (CRISPR/Cas9) genome editing tool.Furthermore, we will also discuss the salient features of CRISPR/Cas9 editing technology and Cas9 variants such as prime and base editors to replicate genetic topographies linked specifically to ALD and NAFLD. The advantages and limitations of currently available genome delivery methods necessary for optimal gene editing will also be discussed in this review. This review will provide the essential guidance for appropriate genome editing tool selection and proper gene delivery approaches for the effective development of ALD and NAFLD models, leading to the development of clinical therapeutics for fatty liver disease.

The Association of Metabolic-Associated Fatty Liver Disease with Clinical Outcomes of COVID-19: A Systematic Review and Meta-Analysis.

Introduction: Metabolic-associated fatty liver disease (MAFLD) is a hepatic manifestation of metabolic syndrome (MS). MAFLD patients have a higher prevalence of COVID-19. MAFLD also is associated with worse clinical outcomes of COVID-19, such as disease severity, intensive care unit (ICU) admission rate, and higher mortality rates. However, this evidence has not been well characterized in the literature. This meta-analysis aimed to determine the clinical outcomes of COVID-19 among MAFLD patients compared to the non-MAFLD group. Methods: A comprehensive search was conducted in the Cumulative Index of Nursing and Allied Health (CINAHL), PubMed/Medline, and Embase for studies reporting MAFLD prevalence among COVID-19 patients and comparing clinical outcomes such as severity, ICU admission, and mortality among patients with and without MAFLD. The pooled prevalence of MAFLD among COVID-19 patients and the pooled odds ratios (OR) with 95% confidence intervals (CI) for clinical outcomes of COVID-19 were calculated. Results: Sixteen observational studies met inclusion criteria involving a total of 11,484 overall study participants, including 1,746 MAFLD patients. The prevalence of COVID-19 among MAFLD patients was 0.29 (95% CI: 0.19-0.40). MAFLD was associated with the COVID-19 disease severity OR 3.07 (95% CI: 2.30-4.09). Similarly, MAFLD was associated with an increased risk of ICU admission compared to the non-MAFLD group OR 1.46 (95% CI: 1.12-1.91). Lastly, the association between MAFLD and COVID-19 mortality was not statistically significant OR 1.45 (95% CI: 0.74-2.84). Conclusions: In this study, a high percentage of COVID-19 patients had MAFLD. Moreover, MAFLD patients had an increased risk of COVID-19 disease severity and ICU admission rate.

Treatments and Sequelae of Pediatric Pathologic Proximal Femur Fractures Due to Benign Bone Cyst.

BACKGROUND: The proximal femur is a common location for pathologic fractures in children, yet there is little published information regarding this injury. The purpose of this study was to investigate the outcomes of pediatric pathologic proximal femur fractures due to benign bone tumors. METHODS: A retrospective review of patients treated for pathologic proximal femur fractures from 2004 to 2018 was conducted. Inclusion criteria were age below 18 years and pathologic proximal femur fracture secondary to a benign bone tumor. Patients were excluded if they had <1 year of follow-up. Medical charts and serial radiographs were reviewed for fracture classification, underlying pathology, treatment, complications, and time to fracture healing. RESULTS: A total of 14 patients were included. Mean age was 6±3 (3 to 11) years, and mean follow-up was 44±21 (22 to 86) months. Index treatment was spica casting in 9/14 (68%) patients, while 5/14 (32%) were treated with internal fixation. Of the 9 patients initially treated with casting, 22% (2/9) required repeat spica casting at a mean of 0.6 months after index treatment, 67% (6/9) required internal fixation at a mean of 20.3 months after index treatment, and 11% (1/9) did not require revision treatment. Eighty-eight percent (8/9) of patients treated with casting required revision treatment compared with 40% (2/5) of those treated with internal fixation (P=0.05). Nonunion occurred after 1 refracture, malunion with coxa vara occurred in 2 fractures, and the remaining 11/14 (84%) fractures had a union at a mean of 4.9±3.0 months All cases of malunion occurred in patients initially treated nonoperatively. There were 19 distinct complications in 10/14 (71%) patients. The incidence of any revision surgery was 64% (9/14). CONCLUSIONS: In this series, pediatric pathologic proximal femur fractures demonstrated prolonged time to union, high incidence of revision surgery (64%), and substantial complication rate (71%). In children with pathologic proximal femur fractures, treatment with internal fixation is recommended as this series showed a 78% failure rate of initial conservative management. LEVEL OF EVIDENCE: Level IV.

Burnout, Professional Fulfillment, Intention to Leave, and Sleep-Related Impairment among Radiology Trainees across the United States (US): A Multisite Epidemiologic Study.

OBJECTIVE: To examine the prevalence of burnout among radiology trainees in the United States, and to study the relationships between burnout and professional fulfillment (PF), intent-to-leave (ITL), sleep-related impairment and self-compassion by gender. METHODS: This cross-sectional study was conducted via an anonymous electronic survey sent to 11 large academic medical centers (Physician Wellness Academic Consortium) between January 2017 and September 2018. The survey included the Professional Fulfillment Index (PFI) and an abbreviated form of the PROMIS Sleep-related impairment (SRI) scale. Two-sample t-tests and chi-square exact tests were used for analysis (p < 0.05). RESULTS: Two hundred forty-seven radiology residents responded to the survey. Out of these, 36.2% reported burnout, 37.4% endorsed PF, 64.8% reported sleep-related impairment, 7.6% expressed ITL. There were no significant differences between genders. Burnout was associated with reduced PF, increased sleep-impairment (p < 0.001 for both) and increased ITL (p = 0.02). Lower PF, peer support, perceived appreciation for and meaningfulness in work, alignment of organizational and personal values, self-compassion, and higher sleep impairment were associated with burnout (p < 0.001 for all). Burnout was associated with perceptions of less support from department leaders (p = 0.003), control over schedules (p = 0.001) and helpfulness of electronic health record systems (p = 0.01). ITL was associated with reduced PF, perceived work appreciation, and leadership support (p = 0.03, p = 0.04, and p = 0.007, respectively). DISCUSSION: Burnout is prevalent among radiology residents. Many demonstrate sleep-impairment and reduced professional fulfillment, with a lesser fraction desiring to leave their institution. Key factors to burnout included peer and organizational support, electronic health record systems helpfulness, and personal factors like self-compassion and work appreciation.

EUS-guided versus percutaneous transhepatic cholangiography biliary drainage for obstructed distal malignant biliary strictures in patients who have failed endoscopic retrograde cholangiopancreatography: A systematic review and meta-analysis.

EUS-guided biliary drainage (EUS-BD) and percutaneous transhepatic cholangiography biliary drainage (PTC) are the two alternate methods for biliary decompression in cases where ERCP fails. We conducted a systematic review and meta-analysis of studies to compare the efficacy and safety of endoscopic and percutaneous biliary drainage for malignant biliary obstruction in patients with failed ERCP. A total of ten studies were included, fulfilling the inclusion criteria, including four retrospective studies and six randomized controlled trials. We compared the technical and clinical success rates and the acute, delayed, and total adverse events of EUS-BD with PTC. The odds ratios (ORs) and confidence intervals (CIs) were calculated. There was no difference between technical (OR: 0.47 [95% CI: 0.20-1.07]; P = 0.27) and clinical (OR: 2.24 [95% CI: 1.10-4.55]; P = 0.51) success rates between EUS-PD and PTC groups. Procedural adverse events (OR: 0.17 [95% CI: 0.09-0.31]; P = 0.03) and total adverse events (OR: 0.09 [95% CI: 0.02-0.38]; P < 0.01) were significantly different between the two groups; however, delayed adverse events were nonsignificantly different (OR: 0.73 [95% CI: 0.34-1.57]; P = 0.97). This meta-analysis indicates that endoscopic biliary drainage (EUS-BD) is equally effective but safer in terms of acute and total adverse events than percutaneous transhepatic biliary drainage (PTC) for biliary decompression in patients with malignant biliary strictures who have failed an ERCP.

An Inverted Acetabular Labrum Is Predictive of Pavlik Harness Treatment Failure in Children With Developmental Hip Dysplasia.

INTRODUCTION: The failure rate of Pavlik harness treatment for developmental dysplasia of the hip (DDH) has been reported as high as 55%. The purpose of this study is to investigate the effect of an inverted acetabular labrum on outcomes of Pavlik harness treatment for DDH. METHODS: A retrospective review was conducted on DDH patients at a tertiary care pediatric hospital from 2004 to 2016. DDH patients that underwent index treatment with Pavlik harness and had minimum 12 months follow-up were included. Medical charts were reviewed for demographics, treatment, and outcomes. Outcomes were compared between patients with an inverted labrum versus those without an inverted labrum. RESULTS: A total of 156 patients with 229 dysplastic hips were included. The mean age at initiation of Pavlik harness treatment was 1.9±1.4 months and mean follow-up was 37.7±23.0 months. Bilateral DDH was diagnosed in 46% (73/156) of patients. In all, 37% (75/229) of hips failed Pavlik harness index treatment. Second-line treatment was rigid hip abduction bracing in 91% (68/75) of hips, closed reduction in 5% (4/75) of hips, and open reduction in 4% (3/75) of hips. An inverted labrum was present in 10% (22/229) of all hips. The incidence of Pavlik harness treatment failure was 91% (20/22) in the inverted labrum group compared with 27% (55/207) in the control group (P<0.001). Closed or open reduction was required in 86% (15/22) of the inverted labrum group compared with 3% (7/207) of hips in the control group (P<0.001). The incidence of avascular necrosis was 18% (4/22) in hips with an inverted labrum compared with 0.4% (1/207) in the control group (P<0.001). CONCLUSIONS: In children with DDH undergoing index treatment in a Pavlik harness, the presence of an inverted acetabular labrum is strongly predictive of treatment failure. Dysplastic hips with an inverted labrum also have a significantly higher risk of requiring closed or open reduction and developing avascular necrosis compared with those without an inverted labrum. LEVEL OF EVIDENCE: Level III.

Pain for Greater Than 4 Days Is Highly Predictive of Concomitant Osteomyelitis in Children With Septic Arthritis.

BACKGROUND: There is no evidence-based consensus on the risk factors for concomitant osteomyelitis and septic arthritis. The purpose of this study was to investigate clinical parameters predictive of concomitant osteomyelitis in children with septic arthritis. METHODS: A retrospective review was conducted on patients with septic arthritis with magnetic resonance imaging (MRI) between January 2004 and October 2016 at a tertiary care pediatric hospital. Medical charts were reviewed for information including symptoms, diagnosis of osteomyelitis, serum laboratory studies, joint fluid analyses, imaging results, and treatment. Positive diagnosis of osteomyelitis was defined as a hyperintense signal of osseous structures on T2-weighted MRI consistent with infection per attending pediatric radiologist final read. RESULTS: A total of 71 patients with 73 septic joints were included. The mean age was 6±4 (0.1 to 17) years and the mean follow-up was 14.9±24.1 (1.0 to 133.1) months. Septic arthritis with concomitant osteomyelitis occurred in 43 of 71 (61%) patients, whereas 28 of 71 (39%) patients had septic arthritis alone. Inflammatory markers such as white blood cell count, erythrocyte sedimentation rate, and C-reactive protein on admission were not associated with concomitant osteomyelitis. Multivariate logistic regression revealed that positive joint fluid bacterial culture (P=0.021) and pain for >4 days before admission (P=0.004) are independent risk factors for concomitant osteomyelitis in children with septic arthritis. Among the 24 septic arthritis patients with pain for >4 days before presentation, 96% (23/24) had concomitant osteomyelitis, whereas 43% (20/47) of patients with pain for ≤4 days had concomitant osteomyelitis. CONCLUSION: Pain for >4 days before presentation is an independent predictor of osteomyelitis in children with septic arthritis. In pediatric septic arthritis, MRI should be considered, particularly in patients presenting with pain for >4 days as 96% of these patients had concomitant osteomyelitis. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

EUS-guided pancreatic ductal intervention: A comprehensive literature review.

EUS has opened a new frontier in endoscopic techniques for accessing pancreatic ducts in patients with failed ERCP. The major indications of EUS-guided pancreatic duct intervention (EUS-PDI) are main pancreatic duct (MPD) strictures due to chronic pancreatitis or strictures of pancreaticojejunal or pancreaticogastric anastomosis after Whipple resection, which lead to recurrent acute pancreatitis. EUS-guided pancreaticogastro or duodenostomy offers an alternative to surgery when transpapillary drainage fails or is not possible. We provide an expert commentary and a brief overview on this relatively novel technique utilizing EUS-PDI creation in patients with impaired drainage of the MPD who have failed other conventional endoscopic techniques for MPD drainage and either are poor surgical candidates or are reluctant to undergo surgery.

Surgical Management of a Displaced Posterior Column Pelvic Fracture Involving the Triradiate Cartilage in a 15-Year-Old Adolescent Boy: A Case Report.

CASE: A 15-year-old adolescent boy sustained a displaced acetabular fracture involving the ilioischial physis of the triradiate cartilage after a ground-level fall. The patient was managed operatively with open reduction and internal fixation and was followed for 9 months postoperatively. At 4 months postoperatively, the patient had resumed full weight bearing on the injured extremity and was participating in sports with no difficulties. CONCLUSION: Pediatric pelvic fractures through the triradiate cartilage are rare, and no consensus exists on the treatment of these injuries. Previous authors largely described nonoperative management with suboptimal outcomes. We present the case of a patient treated with initial operative fixation who successfully returned to full activities.

Using a dedicated spine radiology technologist is associated with reduced fluoroscopy time, radiation dose, and surgical time in pediatric spinal deformity surgery.

STUDY DESIGN: Retrospective comparative study OBJECTIVES: The goal of this study was to investigate fluoroscopy time and radiation exposure during pediatric spine surgery using a dedicated radiology technologist with extensive experience in spine operating rooms. Repetitive use of intraoperative fluoroscopy during posterior spinal fusion (PSF) exposes the patient, surgeon, and staff to radiation. METHODS: Retrospective review was conducted on patients with posterior spinal fusion (PSF) of ≥ 7 levels for adolescent idiopathic scoliosis (AIS) at a pediatric hospital from 2015 to 2019. Cases covered by the dedicated radiology technologist (dedicated group) were compared to all other cases (non-dedicated group). Surgical and radiologic variables were compared between groups. RESULTS: 230 patients were included. 112/230 (49%) were in the dedicated group and 118/230 (51%) were in the non-dedicated group. Total fluoroscopy time was significantly reduced in cases with the dedicated technologist (46 s) compared to those without (69 s) (p = 0.001). Radiation dose area product (DAP) and air kerma (AK) were reduced by 43% (p < 0.001) and 42% (p < 0.001) in the dedicated group, respectively. The dedicated group also had reduced total surgical time (4.1 vs. 3.5 h; p < 0.001) and estimated blood loss (447 vs. 378 cc (; p = 0.02). Multivariate regression revealed that using a dedicated radiology technologist was independently associated with decreased fluoroscopy time (p = 0.001), DAP (p < 0.001), AK (p < 0.001), surgical time (p < 0.001), and EBL (p = 0.02). CONCLUSIONS: In AIS patients undergoing PSF, using a dedicated radiology technologist was independently associated with significant reductions in fluoroscopy time, radiation exposure, surgical time, and EBL. This adds to the growing body of research demonstrating that the experience level of the team-not just that of the surgeon-is necessary for optimal outcomes. LEVEL OF EVIDENCE: III.

The effect of coffee consumption on the non-alcoholic fatty liver disease and liver fibrosis: A meta-analysis of 11 epidemiological studies.

INTRODUCTION AND OBJECTIVES: Non-alcoholic fatty liver disease (NAFLD) is a widespread chronic liver disease. It is considered a multifactorial disorder that can progress to liver fibrosis and cause a worldwide public health concern. Coffee consumption may have a protective impact on NAFLD and liver fibrosis. However, the evidence from the previous studies is inconsistent. This meta-analysis summarizes available literature. MATERIALS AND METHODS: This study comprises two meta-analyses. The first meta-analysis summarizes the effect of coffee consumption on NAFLD in those who did or did not drink coffee. The second analysis compares the risk of liver fibrosis development between NAFLD patients who did or did not drink coffee. Pooled risk ratios (RR) and confidence intervals (CI) of observational studies were estimated. RESULTS: Of the total collected 321 articles, 11 met our eligibility criteria to be included in the analysis. The risk of NAFLD among those who drank coffee compared to those who did not was significantly lower with a pooled RR value of 0.77 (95% CI 0.60-0.98). Moreover, we also found a significantly reduced risk of liver fibrosis in those who drink coffee than those who did not drink in the NAFLD patients with the relative risk (RR) of 0.68 (95% CI 0.68-0.79). CONCLUSIONS: Regular coffee consumption is significantly associated with a reduced risk of NAFLD. It is also significantly associated with decreased risk of liver fibrosis development in already diagnosed NAFLD patients. Although coffee consumption may be considered an essential preventive measure for NAFLD, this subject needs further epidemiological studies.

An international, multi-institution survey on performing EUS-FNA and fine needle biopsy.

BACKGROUND AND OBJECTIVES: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and fine needle biopsy (FNB) are effective techniques that are widely used for tissue acquisition. However, it remains unclear how to obtain high-quality specimens. Therefore, we conducted a survey of EUS-FNA and FNB techniques to determine practice patterns worldwide and to develop strong recommendations based on the experience of experts in the field. METHODS: This was a worldwide multi-institutional survey among members of the International Society of EUS Task Force (ISEUS-TF). The survey was administered by E-mail through the SurveyMonkey website. In some cases, percentage agreement with some statements was calculated; in others, the options with the greatest numbers of responses were summarized. Another questionnaire about the level of recommendation was designed to assess the respondents' answers. RESULTS: ISEUS-TF members developed a questionnaire containing 17 questions that was sent to 53 experts. Thirty-five experts completed the survey within the specified period. Among them, 40% and 54.3% performed 50-200 and more than 200 EUS sampling procedures annually, respectively. Some practice patterns regarding FNA/FNB were recommended. CONCLUSION: This is the first worldwide survey of EUS-FNA and FNB practice patterns. The results showed wide variations in practice patterns. Randomized studies are urgently needed to establish the best approach for optimizing the FNA/FNB procedures.
