- Abstract
The Orthopaedic In-Training Exam (OITE) is administered annually to orthopedic surgery residents to assess their medical knowledge. The authors provide a comprehensive review of the orthopedic oncology portion of the exam in order to aid residents in preparation for future in-training and licensing examinations as well as to help guide oncology residency education curriculum. All of the orthopedic oncology questions on the OITE from 2007 to 2019 were reviewed. Analysis included (1) the number of oncology questions each year, (2) question topic, (3) question taxonomy (knowledge versus interpretation), (4) the type of imaging modalities (radiological, histological), (5) most commonly cited references, and (6) level of evidence. Descriptive statistics were utilized to compare means between variables. From 2007 to 2019, there was a total of 292 tumor-related questions with a mean of 22.5 tumor-related questions (range 19-28) per year. Of the questions, 54.8% pertained to malignant tumors and 45.2% to benign tumors. Assessment of question taxonomy showed that 79.8% of questions required interpretation of imaging and analysis of the information provided versus 20.2% of questions being knowledge recall type. Of the questions, 76.7% required interpretation of radiological images, pathological images, or both. Orthopaedic Knowledge Update, Journal of the American Academy of Orthopaedic Surgeons, and Journal of Bone and Joint Surgery were the three most commonly cited question sources. Only 29 (9.84%) oncology questions over the past 13 years have been supported by level I or II sources of evidence. Better understanding of the OITE make-up, question distribution, and number and style of question, reference sources can improve an orthopedic residents' performance as well as better guide educational curriculum to prepare residents in their orthopedic oncology education.

- Abstract
Background Routine analysis of bone specimens in total joint arthroplasty (TJA) is mandatory at many institutions. The purpose of this study was to determine if mandatory routine TJA specimen analysis alters patient care or if they represent an unnecessary healthcare expenditure. Methods A retrospective review was performed of all primary TJA patients between October 2015 and December 2017 at our institution. Pathology results were reviewed to ascertain the number of concordant, discrepant, and discordant results. A diagnosis was considered concordant if the preoperative and pathologic diagnosis matched, discrepant if the preoperative and pathological diagnosis differed but no change in the patient's plan of care occurred, and discordant if the preoperative and pathologic diagnosis differed and resulted in a change in the patient's plan of care. Results 3,670 total hip arthroplasty (THA) and total knee arthroplasty (TKA) procedures (3,613 patients) met the inclusion criteria and were included in this study. All 3,670 specimens had a concordant diagnosis; there were zero discrepant and zero discordant diagnoses. During the study period, our institution spent $67,246.88 in routine analysis of TJA specimens by a pathologist, with no change in any postoperative patient care plans. Conclusion With bundled payment reimbursement models and hospitals trying to decrease unnecessary expenditures, the present study helps further demonstrate that routine analysis has limited cost-effectiveness due to the low prevalence of alteration in the management of patient care. The decision for pathological analysis should be left at the discretion of the surgeon in order to maximize the cost-efficiency of TJA procedures., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2021, Koss et al.)

- Abstract
Hip joint dislocation is the most common complication after a proximal femur replacement. As the utilization of proximal femur replacements continues to increase, it becomes imperative for surgeons to find the optimal method to decrease postoperative dislocation and its sequelae. These cases often involve extensive soft-tissue deficits that require reconstruction to provide postoperative strength and stability. Patients report good functional outcomes; however, dislocation remains a concern. Although "described" previously in the literature, the authors illustrate the "purse-string" hip joint capsular closure technique to help other surgeons understand it and apply to their practice as deemed necessary. We also present the senior author's results with using a modified version of the "purse-string" hip joint capsular closure technique., (Copyright © 2020 The Authors.

- Abstract
The humerus is a common site of metastatic tumor involvement and pathologic fracture. Intramedullary nailing is a treatment option that offers the benefit of protecting a long segment of diseased bone, but it is not without complications. This study aims to examine the survival, functional outcomes, and complications of patients treated with cement-augmented unlocked intramedullary nailing for actual and impending pathologic fractures of the humeral shaft., Methods: From 2014 to 2019, 26 patients were treated with this technique. Functional outcomes were assessed using the Musculoskeletal Tumor Society scoring system. Outcome scores, complications, reoperations, and mortality were determined by retrospective chart reviews and direct patient examinations., Results: The mean age at the time of surgery was 66.8 years. The mean follow-up was 20.2 months. Patients reported significant improvement in the mean Musculoskeletal Tumor Society score from 10.5 preoperatively to 26.1 after surgery ( P < 0.001). Five patients died of disease during the follow-up period. One patient had intraoperative fracture propagation during implant placement, and one patient experienced a postoperative rotator cuff tear., Discussion: Unlocked intramedullary nailing with cement augmentation is a reliable treatment method for actual and impending pathologic fractures of the humerus that results in favorable outcomes, including consistent pain relief and restoration of function., Competing Interests: None of the following authors or any immediate family member has received anything of value from or has stock or stock options held in a commercial company or institution related directly or indirectly to the subject of this article: Dr. Pizzo, Mr. Hoskins, Dr. Patel, Dr. Miller, Mr. Goyette, Mr. Mazzei, and Dr. Wittig., (Copyright © 2020 The Authors.

- Abstract
Background: Postoperative infection is one of the most prevalent complications following total joint arthroplasty (TJA). As such procedures become more prevalent, it is imperative that we develop new prophylactic methods to prevent the need for revision procedures. In recent years, surgeons have opted to use antibiotic-loaded bone cement (ALBC) rather than plain bone cement (PBC) in primary hip and knee replacements due to its theoretical potential of lowering infection rates. However, the cost-effectiveness of this intervention remains in question.Questions/Purposes: To determine the rate of infection and cost-effectiveness of antibiotic-loaded bone cement as compared to plain bone cement in hip and knee arthroplasty., Patients and Methods: We reviewed 4116 primary hip and knee arthroplasty cases performed between 2016 and 2018 at Morristown Medical Center in New Jersey. Data regarding demographics, complications, and any readmissions due to deep infection were collected retrospectively. During that time period there were a total of 4016 knee cases (423 ALBC, 3593 PBC) and 123 hip cases (63 ALBC, 60 PBC). The average cost for one bag of antibiotic-loaded bone cement and plain bone cement for hip and knee arthroplasty was $336.42 and $72.14, respectively. A statistical analysis was performed using Fisher's exact test; the National Healthcare Safety Network (NHSN) surgical site infection guidelines were used to distinguish between superficial and deep infections., Results: Ten patients were readmitted due to deep infection, all of whom had undergone total knee arthroplasty. Of those cases, plain bone cement was used for the index procedure in seven instances and antibiotic-loaded cement was used in three. This resulted in an infection rate of 0.19% and 0.62%, respectively, p = 0.103. There was no statistically significant difference in infection rates between the two groups. A total of 778 bags of ALBC were used in 423 knee surgeries, and 98 bags of ALBC were used in 63 hip cases. The total cost for ALBC in TKA and THA procedures was $261,734.76 (778*336.42) and $32,969.16 (98*336.42), respectively. If PBC had been used during all index procedures, it would have resulted in a total savings of $231,509.28., Conclusions: Antibiotic-loaded cement did not significantly reduce the rate of infection for either knee or hip arthroplasty. Thus, the routine use of antibiotic-loaded cement in primary hip and knee arthroplasty may be an unnecessary financial burden to the healthcare system. A larger sample size and a randomized controlled trial would help confirm our findings and would provide further information on the cost-effectiveness of ALBC cement versus PBC.Significance/Clinical Relevance: In this review of cases performed from 2016 to 2018 there was no statistically significant difference between the rate of infection and the need for revision surgeries for patients treated with ALBC versus PBC. As hospital systems continue to transition towards a bundled payment model, it becomes imperative for providers to reduce any unnecessary costs in order to increase quality and efficiency. We estimate that our hospital system could save nearly $120,000/year by using plain bone cement instead of antibiotic-loaded cement., Competing Interests: “Each author certifies that he or she has no commercial associations (eg, consultancies, stock ownership, equity interest, patent/licensing arrangements, etc) that might pose a conflict of interest in connection with the submitted article.”, (Published by Elsevier B.V. on behalf of Professor P K Surendran Memorial Education Foundation.)

- Abstract
Nitric oxide (NO) is a potential regulator of ischemic vascular remodeling, and as such therapies augmenting its bioavailability may be useful for the treatment of ischemic tissue diseases. Here we examine the effect of administering the NO prodrug sodium nitrite on arteriogenesis activity during established tissue ischemia. Chronic hindlimb ischemia was induced by permanent unilateral femoral artery and vein ligation. Five days postligation; animals were randomized to control PBS or sodium nitrite (165 μg/kg) therapy twice daily. In situ vascular remodeling was measured longitudinally using SPY angiography and Microfil vascular casting. Delayed sodium nitrite therapy rapidly increased ischemic limb arterial vessel diameter and branching in a NO-dependent manner. SPY imaging angiography over time showed that nitrite therapy enhanced ischemic gracillis collateral vessel formation from the profunda femoris to the saphenous artery. Immunofluorescent staining of smooth muscle cell actin also confirmed that sodium nitrite therapy increased arteriogenesis in a NO-dependent manner. The NO prodrug sodium nitrite significantly increases arteriogenesis and reperfusion of established severe chronic tissue ischemia.

- Abstract
Opportunities abound for pharmacists to expand their practices by providing clinical services or assuring access to affordable pharmaceuticals to the medically underserved. The PSSC is a recently established resource at APhA that provides the pharmacy community and HRSA grantees with information and technical assistance on HRSA programs and projects. By participating in HRSA demonstration projections, pharmacists can implement much greatly needed patient care services to reduce disparities in health care. Becoming a 340B-contracted pharmacy can help pharmacists build prescription volume, expand their clinical services, and better serve the health care needs of their communities.

- Abstract
A new surgical procedure with potential application for the treatment of adductor spasmodic dysphonia was performed on ten rabbits to assess surgical effects on laryngeal function. Using an external approach, partial unilateral thyroarytenoid (TA) muscle excision was performed through a thyroplasty cartilage window. The contralateral side was left undisturbed as a control. The animals were studied acutely and at 3 months using videolaryngoscopy. Electrophysiologic measurements were recorded at 3 months. The procedure was well tolerated by all animals, with no postoperative infection or aspiration. At 3 months, spontaneous and evoked (recurrent laryngeal nerve stimulation) TA muscle electromyographic potentials were measurable bilaterally. TA compound muscle action potential amplitudes were reduced on the side of myectomy. The threshold of recurrent laryngeal nerve stimulation needed to produce observable vocal fold adduction was increased on the side operated on. Perioperative and long-term (3 months) videolaryngoscopy demonstrated preservation of laryngeal competence with good true vocal cord adduction. Histologic analysis with whole organ sections showed replacement of excised muscle with loose fibroareolar tissue. No evidence of muscle regeneration was observed. The vocal ligament and vocal fold mucosa were intact and undistorted in all specimens. This procedure is technically simple and appears to effectively result in a functional yet weakened TA muscle. Because myectomy includes motor unit end-plate excision, problems associated with reinnervation may be circumvented. TA myectomy may be applicable in patients with focal laryngeal dystonia to decrease muscle spasm.

- Abstract
The effects of plasma lavage on pulmonary surfactant and edema were studied in anesthetized open-chest dogs. After instrumentation and baseline measurements, citrated autologous plasma (1.5 ml/kg) was lavaged into each lung (n = 6). A control group was administered the same dose of buffered saline solution (n = 4). Hemodynamic parameters, blood gases, and lung compliance were monitored for 2 hours after lavage. Surfactant function, assessed with a Wilhelmy balance, and extravascular lung water measured gravimetrically were determined at the end of the experiment. Immediately after plasma lavage, a nonsegmental atelectasis was observed on the lung surface. Little change was seen in vascular pressures or cardiac output in either group, whereas partial pressure of oxygen in arterial blood and static compliance fell significantly after plasma lavage. Two hours after lavage, a large amount of white foam was observed in both large and small airways in the plasma group. Plasma but not saline lavage elevated surface tension minimum in pulmonary tissue. Airway foam contained functional surfactant; addition of plasma to normal surfactant on the Wilhelmy balance did not inhibit surfactant function. Extravascular lung water was increased in the plasma compared with the saline lavage group. These data suggest that plasma usurps surfactant from the alveolar hypophase rather than inhibiting its ability to lower surface tension. Because little change was measured in vascular pressures and it is unlikely that autologous plasma increases vascular permeability, we conclude that the edema was the result of high alveolar surface tension.

- Abstract
Inhalation injury occurs in 21% of flame burn victims who require large fluid volumes for resuscitation and have a mortality rate greater than 30%. This study was done to determine how vulnerable the smoke-injured lung is to fluid accumulation when crystalloids are infused rapidly. Mongrel dogs were exposed to smoke and 10% body-weight Ringer's lactate in three groups: (I) fluid only, (II) smoke only, and (III) smoke and fluid. The increase in wet-dry lung weight ratio was 2% in Group I, 28% in Group II, and 42% in Group III, consistent with pulmonary edema present only in Group III. The decrease in colloid oncotic pressure was similar in both of the groups that were given fluid, and the rise in the surface tension minimum of lung extracts was similar in both of the groups that were exposed to smoke. The smoke-injured lung loses the ability to protect itself when challenged with fluid. Reduced oncotic pressure is not responsible. Changes in microvascular pressure, endothelial and epithelial damage, and surfactant inactivation interact to cause this increase in extravascular lung water.

- Abstract
The effect of wood smoke inhalation (SI) on pulmonary vascular permeability was studied in open-chested, anesthetized dogs. Animals were divided into two groups. A prenodal lymphatic vessel was cannulated in group I (n = 7), and baseline (BL) lung lymph flow (QL) and lymph (CL) and plasma (CP) protein concentrations were measured. The animals' lungs were then ventilated with wood smoke for 5 minutes. Left atrial pressure (Pla) was increased above baseline (mean 16.7 +/- 2.2 mm Hg), and the ratio of CL to CP was used to assess endothelial permeability at high lymph flows. There was little change in either QL (BL: 27 +/- 9; SI: 27 +/- 5 microliters/min) or CL/CP (BL: 0.76 +/- 0.03; SI: 0.74 +/- 0.02) after SI at normal Pla. Elevation of Pla caused a significant increase in QL (136 +/- 15 microliters/min), but CL/CP (0.67 +/- 0.02) failed to decrease significantly at high lymph flows. In group II (n = 15) total protein concentration of airway fluid was compared with that of plasma after smoke inhalation, intravenous alloxan, and increased Pla. The ratio of protein concentration in airway fluid to plasma after SI (0.70 +/- 0.07) was greater than that obtained with increased Pla (0.64 +/- 0.07) but less than that after alloxan (0.85 +/- 0.04). These data indicate that SI in the dog results in a moderate increase in pulmonary vascular permeability that is less severe than that induced by alloxan.
