Abstract
Background Given the paucity of literature regarding compensatory mechanisms used by obese patients with sagittal malalignment, it is necessary to gain a better understanding of the effects of obesity on compensation after comparing the degree of malalignment to age-adjusted ideals. This study aims to compare baseline alignment of obese and nonobese patients using age-adjusted spino-pelvic alignment parameters, describing associated spinal changes. Methods Patients ≥ 18 years with full-body stereoradiographs were propensity-score matched for sex, baseline pelvic incidence (PI), and categorized as nonobese (body mass index < 30kg/m2) or obese (body mass index ≥ 30). Age-adjusted ideals were calculated for sagittal vertical axis, spino-pelvic mismatch (PI-LL), pelvic tilt, and T1 pelvic angle using established formulas. Patients were stratified as meeting alignment ideals, being above ideal, or being below. Spinal alignment parameters included C0-C2, C2-C7, C2-T3, cervical thoracic pelvic angle, cervical sagittal vertical axis SVA, thoracic kyphosis, T1 pelvic angle, T1 slope, sagittal vertical axis, lumbar lordosis (LL), PI, PI-LL, pelvic tilt. Lower-extremity parameters included sacrofemoral angle, knee flexion (KA), ankle flexion (AA), pelvic shift (PS), and global sagittal angle (GSA). Independent t tests compared parameters between cohorts. Results Included: 800 obese, 800 nonobese patients. Both groups recruited lower-extremity compensation: sacrofemoral angle (P = .004), KA, AA, PS, GSA (all P < .001). Obese patients meeting age-adjusted PI-LL had greater lower-extremity compensation than nonobese patients: lower sacrofemoral angle (P = .002), higher KA (P = .008), PS (P = .002), and GSA (P = .02). Obese patients with PI-LL mismatch higher than age-adjusted ideal recruited greater lower-extremity compensation than nonobese patients: higher KA, AA, PS, GSA (all P < .001). Obese patients showed compensation through the cervical spine: increased C0-C2, C2-C7, C2-T3, and cervical sagittal vertical axis (all P < .001), high T1 pelvic angle (P < .001), cervical thoracic pelvic angle (P = .03), and T1 slope (P < .001), with increased thoracic kyphosis (P = .015) and decreased LL (P < .001) compared to nonobese patients with PI-LL larger than age-adjusted ideal. Conclusions Regardless of malalignment severity, obese patients recruited lower-limb compensation more than nonobese patients. Obese patients with PI-LL mismatch larger than age-adjusted ideal also develop upper-cervical and cervicothoracic compensation for malalignment. Level of Evidence III. Clinical Relevance Clinical evaluation should extend to the cervical spine in obese patients not meeting age-adjusted sagittal alignment ideals.

Abstract
BACKGROUND Despite advances in technology, graft rupture rates reported in the literature following anterior cruciate ligament (ACL) surgery range from 1.8% to 18%. Recent anatomical studies have identified a lateral structure, the anterolateral ligament (ALL), as a potential source of residual pivoting following ACL reconstruction. The purpose of this report is to review the history surrounding the ALL and recent anatomic studies, identify its biomechanical and clinical implications, and develop a practical approach to utilizing it during ACL reconstruction. METHODS An extensive review of the historical and current literature surrounding the identification of the ALL, its biomechanical function, reconstruction, and outcomes of ALL reconstruction was performed. DISCUSSION After the storm of media coverage surrounding the "new ligament" known as the ALL, much attention was focused on cadaveric dissection, biomechanical analysis, and reconstruction of this structure. Several techniques have been described, and currently studies are being performed both retrospectively and prospectively to evaluate the added benefit of ALL reconstruction to the rotational stability of the knee and outcomes after ACL reconstruction. CONCLUSION The ALL is a lateral-based structure that provides rotational stability to the knee in the presence of ACL deficiency. Reconstruction of this ligament may provide added benefit to stability and outcomes following ACL reconstruction in certain patient populations. Further randomized controlled trials are needed to elucidate the true benefit of ALL reconstruction and those patients who should undergo this added procedure.

Abstract
Asthma is an obstructive lung disease affecting >230 million people worldwide and a significant cause of morbidity in patients of all ages. It is a heterogeneous disease with a complex pathophysiology and phenotype. Diagnosis is made with thorough history-taking and physical examination, and the condition is characterised by variable airflow obstruction and airway hyper-responsiveness. Understanding the severity of the disease is important, and treatment is aimed at symptom control and the prevention of future exacerbations. Pharmacologic treatment with beta-agonists for intermittent asthma and inhaled corticosteroids and a combination of inhaled corticosteroids and long-acting beta-2 agonists for persistent asthma are recommended. Additional and alternative treatments with leukotriene modifiers, anticholinergics, biologics, and bronchial thermoplasty are also available. However, understanding an individual’s disease phenotype, endotype, and comorbidities is necessary for asthma treatment, with appropriate consultation with asthma specialists required for those with severe asthma.

Abstract
The COPD Genetic Epidemiology (COPDGene®) study provides a rich cross-sectional dataset of patients with substantial tobacco smoke exposure, varied by race, gender, chronic obstructive pulmonary disease (COPD) diagnosis, and disease. We aimed to determine the influence of race, gender and Global initiative for chronic Obstructive Lung Disease (GOLD) stage on prevalence of prior COPD diagnosis at COPDGene® enrollment. Data from the complete phase 1 cohort of 10,192 participants were analyzed. Participants were non-Hispanic white and African-American, ≥45 years of age with a minimum of 10 pack years of cigarette smoking. Characterization upon enrollment included spirometry, demographics and history of COPD diagnosis determined by questionnaire. We evaluated the effects of race and gender on the likelihood of prior diagnosis of COPD and the interaction of race and GOLD stage, and gender and GOLD stage, as determined at study enrollment, on likelihood of prior diagnosis of COPD. We evaluated the 3-way interaction of race, gender and GOLD stage on prior diagnosis. African-Americans had higher odds of not having a prior COPD diagnosis at all GOLD stages of airflow obstruction versus non-Hispanic whites (p<0.0001). Women had higher odds of having a prior COPD diagnosis at all GOLD stages versus men (p<0.0001). Three-way interaction of race, gender and GOLD stage was not significant. African-Americans were less likely to have prior COPD regardless of the severity of airflow obstruction determined at study enrollment. Women were more likely to have a prior COPD diagnosis regardless of the severity of measured airflow obstruction. Race and gender are associated with significant disparities in COPD diagnosis.

Abstract
BACKGROUND Anterior cervical discectomy and fusion (ACDF) may be performed using an interbody cage or graft with an anterior plate or with a stand-alone (SA) interbody device without the anterior plate. The pros and cons of each vary. This study examined the radiographic outcome of the two techniques with a focus on implant subsidence. METHODS A retrospective review of cases of singe level ACDF by a single surgeon was undertaken. Medical and radiographic records were reviewed to determine subsidence, pre- and post-operative segmental and total lordosis in cohorts of both stand-alone and graft-and-plate constructs. RESULTS The post-operative radiographs of 35 patients with a SA cage were compared with 41 patients with an allograft block and anterior plate (graft and plate; GP). There was no significant difference in overall subsidence between the two groups although there was a trend toward less clinically significant subsidence (2 mm) in the SA group. For single level ACDF, a SA device appears to be comparable in terms of undesired subsidence. CONCLUSIONS Further studies with different implants and materials may offer further insight.

Abstract
The acetabular labrum and the transverse acetabular ligament form a continuous ring of tissue on the periphery of the acetabulum that provides a seal for the hip joint and increases the surface area to spread load distribution during weight-bearing. When a labral tear is suspected, the treatment algorithm always begins with conservative management, including physical therapy and nonsteroidal anti-inflammatory drugs. When conservative management fails, patients become candidates for arthroscopic labral repair. In the last 2 decades, the rate of hip arthroscopy has increased nearly 4-fold. However, as hip arthroscopy is performed more frequently, there is a need for a proper technique to minimize morbidity, because hip arthroscopy has been known to have a steep learning curve. We present a method for arthroscopic hip labral repair using suture anchors without a capsular repair. This Technical Note highlights our technique for labral repair, along with pearls and pitfalls of hip arthroscopy.

Abstract
BACKGROUND Most patients who undergo total hip arthroplasty are very satisfied with their outcomes. However, there is a small subset of patients who have persistent pain after surgery. The etiology of pain after total hip arthroplasty varies widely; however, tendon disorders are a major cause of debilitating pain that often go unrecognized. METHODS We performed a literature review to identify the most common tendon pathologies after total hip arthroplasty which include iliopsoas tendinitis, greater trochanteric pain syndrome, snapping hip syndrome, and abductor tendinopathy. RESULTS We present a simplified approach highlighting the presentation and management of patients with suspected tendinopathies after total hip arthroplasty. These tendinopathies are treatable, and management begins with nonoperative modalities; however, in cases not responsive to conservative management, operative intervention may be necessary. CONCLUSION Tendinopathies after total hip arthroplasty sometimes go unrecognized but when treated can result in higher surgeon and patient satisfaction.

Abstract
Spinal cord compression due to synovial facet cyst in thoracolumbar spine is rare. Several etiologies of juxtafacet cysts (JFCs) in this location have been discussed, particularly overload of the arthritic facet joints. Due to the narrow caliber of the thoracic spine, JFC in this location can present with radicular pain or progressive myelopathy. We report an interesting case of a 67 year-old woman who presented with the signs and symptoms of thoracic myelopathy. A left-sided T11/12 JFC was identified on MRI and CT scans correlating with her myelopathy. She experienced a substantial improvement in her myelopathic symptoms after surgical excision of the JFC. The presentation, etiology, and therapeutic aspects of JFC are discussed in detail.

Abstract
BACKGROUND Mast cells are present in the airways of patients who have severe asthma despite glucocorticoid treatment; these cells are associated with disease characteristics including poor quality of life and inadequate asthma control. Stem cell factor and its receptor, KIT, are central to mast-cell homeostasis. We conducted a proof-of-principle trial to evaluate the effect of imatinib, a KIT inhibitor, on airway hyperresponsiveness, a physiological marker of severe asthma, as well as on airway mast-cell numbers and activation in patients with severe asthma. METHODS We conducted a randomized, double-blind, placebo-controlled, 24-week trial of imatinib in patients with poorly controlled severe asthma who had airway hyperresponsiveness despite receiving maximal medical therapy. The primary end point was the change in airway hyperresponsiveness, measured as the concentration of methacholine required to decrease the forced expiratory volume in 1 second by 20% (PC20). Patients also underwent bronchoscopy. RESULTS Among the 62 patients who underwent randomization, imatinib treatment reduced airway hyperresponsiveness to a greater extent than did placebo. At 6 months, the methacholine PC20 increased by a mean (±SD) of 1.73±0.60 doubling doses in the imatinib group, as compared with 1.07±0.60 doubling doses in the placebo group (P=0.048). Imatinib also reduced levels of serum tryptase, a marker of mast-cell activation, to a greater extent than did placebo (decrease of 2.02±2.32 vs. 0.56±1.39 ng per milliliter, P=0.02). Airway mast-cell counts declined in both groups. Muscle cramps and hypophosphatemia were more common in the imatinib group than in the placebo group. CONCLUSIONS In patients with severe asthma, imatinib decreased airway hyperresponsiveness, mast-cell counts, and tryptase release. These results suggest that KIT-dependent processes and mast cells contribute to the pathobiologic basis of severe asthma.

Abstract
Endobronchial valve (EBV) therapy has shown improvement in symptoms and lung function despite limited understanding of ideal patient selection. The impact of lobe selection on EBV therapy is unclear. We performed a retrospective analysis to determine the role of lobe selection and identify preprocedure predictors of response to EBV therapy. A total of 492 patients from the USA and Europe were randomized to EBV or control therapy. Spirometry and functional measurements were taken at baseline and 12 months later. At 365 days patients undergoing EBV therapy showed improvement in FEV1 change compared to control regardless of treatment to upper or lower. There was no difference in FEV1 change between the upper and lower lobe treatment groups ( 5 .99, 7.04, p = 0.75). In addition lobe selection was not identified as a significant modifier of FEV1 change in multiple linear regression analysis. Complete lobe fissure was the only significant predictor of FEV1 change (OR 4.14 (2.29, 7.47)). Our results suggest that lobe selection does not play a major role in EBV therapy response. Complete fissure status preprocedure has the greatest influence on FEV1 improvement. These results have implications on patient selection for current treatment and in future EBV studies.

Abstract
BACKGROUND CONTEXT Concurrent ossification of the ligamentum flavum (OLF) in the cervical, thoracic, and lumbar spine is a rare occurrence often associated with rheumatologic abnormalities. Although the pathology may be asymptomatic and discovered incidentally on routine imaging, compression of the cord and surrounding nerve roots can produce myelopathic or radiculopathic symptoms that are best treated with surgical decompression. There is limited evidence to support the use of single versus multistage decompression for tandem ossification at multiple levels, although several factors including duration of symptoms have been associated with a worse prognosis. PURPOSE To describe the presence of extensive symptomatic tandem OLF with concurrent ossification of the posterior longitudinal ligament (PLL) and its treatment using multistage decompression. STUDY DESIGN Case report and literature review. METHODS The authors describe a case of a 35-year-old woman with OLF extending from the cervical to lumbar spine and tandem ossification of the cervical PLL. Her initial presentation was significant for symptoms consistent with thoracic myelopathy in the absence of radiculopathic findings, and initial imaging also demonstrated disc herniation at L4-L5 and L5-S1. RESULTS The patient was first treated with a thoracic laminectomy and fusion from T7 to T11, given her back pain and thoracic myelopathy. Persistence of myelopathic symptoms necessitated further surgical intervention with a posterior cervical decompression and fusion from C3 to T1. Finally, after the appearance of radiculopathic findings, she underwent a microscopic L4-L5 laminectomy with improvements in her symptoms and ambulation. CONCLUSIONS Symptomatic OLF in non-East Asian population is a rare occurrence. Its etiology is likely multifactorial, involving both biomechanical and genetic factors. Although early detection and management are necessary, multistage decompression can be an effective intervention for extensive multilevel ossification.

Abstract
Intertrochanteric hip fractures typically become deformed by the muscular and gravitational forces acting on the 2 main bony fragments. Traditional use of a fracture table for anatomical reduction normally corrects for the varus angulation, external rotation, and posterior sag that can occur, but, in select unstable and comminuted fractures, reduction may not be possible because of posterior sag and external rotation of the proximal fragment. These aspects of malreduction have been addressed in multiple ways, including use of unscrubbed assistants, crutches, internal rotation of the distal fragment by internal rotation of the foot, bumps and pads, and even intraoperative techniques. However, these techniques tend to adjust only 1 aspect of malreduction and may require intraoperative adjustment. In this article, we describe a novel surgical device, the pneumatic patient positioner, that can be used to address these deformities without the need for intraoperative adjustment.

Abstract
Ground pork patties were inoculated separately with 10(9) CFU/g each of three strains of Listeria monocytogenes obtained from the National Animal Disease Center (NADC). Inoculated patties were packaged under vacuum and treated at 414 megapascals (60,000 lb/in2) for up to 60 min by high hydrostatic pressure (HHP). Survivors were determined by surface plating onto modified Oxford agar and trypticase soy agar with yeast extract, as well as by the most probable number method using Listeria enrichment broth. Average D values ranged from 1.89 to 4.17 min, depending on the strain, with the most virulent strain (reported by the NADC) having the highest D value. We tested the usefulness of applying a mild heat treatment at 50 degrees C, simultaneously with HHP, to lower these values. Average D values ranged from 0.37 to 0.63 min, depending on the strain. Thus, a 10-log10 reduction could be achieved even in the most pressure-resistant strain of L. monocytogenes by a 6-min application of heat and HHP. Shelf life studies were also conducted, with spoilage levels reached after 5 days of storage at 4 degrees C for controls versus 28 days for treated samples. Sensory evaluation of uninoculated grilled patties showed that panelists could not distinguish between those treated by heat and HHP and untreated controls (P<0.05). Thus, treatment by HHP in combination with mild heating can be used successfully to produce safer, longer-lasting fresh pork without affecting quality.

Abstract
UNLABELLED In this prospective, randomized, double-blind, placebo-controlled study, we examined the effect of preoperative dexamethasone on postoperative nausea and vomiting (PONV) and 24-h recovery in children undergoing tonsillectomy. One hundred thirty children, 2-12 yr of age, ASA physical status I or II, completed the study. All children received oral midazolam 0.5-0.6 mg/kg preoperatively. Anesthesia was induced with halothane and nitrous oxide in 60% oxygen and maintained with nitrous oxide and isoflurane. Intubation was facilitated by mivacurium 0.2 mg/kg. Each child received fentanyl 1 microgram/kg i.v. before initiation of surgery, as well as dexamethasone 1 mg/kg (maximal dose 25 mg) (steroid group) or an equal volume of saline (control group). Intraoperative fluids were standardized to 25-30 mL/kg lactated Ringer's solution. All tonsillectomies were performed under the supervision of one attending surgeon using an electrodissection technique. Postoperatively, fentanyl and acetaminophen with codeine elixir were administered as needed for pain. Rescue antiemetics were administered when a child experienced two episodes of retching and/or vomiting. Before home discharge, the incidence of PONV, need for rescue antiemetics, quality or oral intake, and analgesic requirements did not differ between groups. However, during the 24 h after discharge, more patients in the control group experienced PONV (62% vs 24% in the steroid group) and complained of poor oral intake. Additionally, more children in the control group (8% vs 0% in the steroid group) returned to the hospital for the management of PONV and/or poor oral intake. The preoperative administration of dexamethasone significantly decreased the incidence of PONV over the 24 h after home discharge in these children. IMPLICATIONS In this double blind, placebo-controlled study, we examined the efficacy of a single large dose (1 mg/kg; maximal dose 25 mg) of preoperative dexamethasone on posttonsillectomy postoperative nausea and vomiting (PONV) in children 2-12 yr of age undergoing tonsillectomy. Compared with placebo, dexamethasone significantly decreased the incidence of PONV in the 24 h after discharge, improved oral intake, decreased the frequency of parental phone calls, and resulted in no hospital returns for the management of PONV and/or poor oral intake.

Abstract
Earlier studies conducted in our laboratory showed that heat-shocked Yersinia enterocolitica (45 degrees C for 60 min) are more resistant to a subsequent beat treatment of 55 or 60 degrees C in ground pork than cells not previously heat-shocked. The increased thermotolerance was partly attributed to the production of stress proteins. The present study was performed to determine if the stress proteins produced by heating could also afford protection to the cells to irradiation. As part of the study, the effect of air versus vacuum packaging on survival of Yersinia to irradiation was also examined. Irradiating the inoculated pork at 1.0 kGy was sufficient to completely eliminate this pathogen. The irradiation D value for both heat-shocked and non-heat-shocked cells was statistically the same (0.15 kGy). Neither heat-shocking Yersinia nor packaging under vacuum resulted in increased resistance of this organism to irradiation. In addition, no effect was seen in virulence of the cells after these treatments, when compared with controls.
