Purpose To investigate the differences in survival after venous thromboembolism (VTE) and anticoagulation efficacy and safety between catheter (CRVTE) and non-catheter-related VTE (NCRVTE) in cancer patients. Methods A retrospective research was conducted, and consecutive cancer (digestive, respiratory, genitourinary, blood and lymphatic, and the other cancers) patients with VTE were enrolled. The anticoagulation therapies included low-molecular-weight heparin (LMWH), warfarin, new type of direct oral anticoagulants (NDOACs), LMWH combined with warfarin, and LMWH combined with NDOACs. Data were collected from the electronic medical record database of our hospital and were analyzed accordingly by Kruskal-Wallis H Test, Chi-square test, Fisher's exact test, Logistic regressions, Kaplan-Meier analysis, and Cox regressions. Results 263 patients were included, median age in years (interquartile range) was 64(56-71) and 60.5% were male. VTE recurrence rate was 16.7% in CRVTE group which was significantly lower than 34.8% in NCRVTE group ( P = .032). Heart diseases were independently associated with VTE recurrence ( P = .025). Kaplan-Meier survival estimates at 1, 2, and 3 years for CRVTE group were 62.5%, 60.0%, and 47.5%, respectively, compared with 47.9% ( P = .130), 38.7% ( P = .028), and 30.1% ( P = .046), respectively, for NCRVTE group. Cox regression showed surgery ( P = .003), anticoagulation therapy types ( P = .009), VTE types ( P = .006) and cancer types ( P = .039) were independent prognostic factors for 3-year survival after VTE. Nonmajor and major bleeding were not significantly different ( P = .417). Anticoagulation therapy types were independently associated with the bleeding events ( P = .030). Conclusions Cancer patients with CRVTE potentially have a better anticoagulation efficacy and survival compared to NCRVTE, and the anticoagulation safety seems no significant difference.

Summary:. Scaphoid nonunion occurs in 10%–15% of scaphoid fractures, potentially resulting in scaphoid nonunion advanced collapse. Distal scaphoid excision without allograft interposition is a known treatment, but can result in loss of carpal height and pain. This report describes the application of human acellular dermal matrix as an interposition graft after distal scaphoid excision for stage I scaphoid nonunion advanced collapse. Postoperatively, the patient initiated early range of motion and returned to full activity at 6 weeks. He demonstrated resolution of his pain 6 years later.

Background:. Chronic venous leg ulcers (VLUs) are a common manifestation of chronic venous insufficiency, accounting for up to 70% of all chronic leg ulcers. Patients sustained refractory ulcers and persistent phleboedema even with a combination of different treatment methods. Lymphovenous bypass (LVB) has shown promising results in patients with lymphedema. We hypothesize that LVB could potentially alleviate VLUs and phleboedema, given their symptom similarities with lymphedema. Methods:. From May 2021 to June 2023, we prospectively deployed LVB in patients with nonhealing stasis ulcers after 4-week traditional care, or in those with persistent phleboedema despite prior surgery for vein etiologies. Demographics, healing course and recurrence, lymphoscintigraphy, and VLU quality of life (QoL) questionnaires were collected. Results:. Thirty-one patients were treated with LVB and additional skin grafting as necessary. Their mean age was 62.6 ± 14.7 years, with male predominance (20, 64.5%), and most patients sustained clinical, etiologic, anatomic, pathophysiologic classification C6 (25, 80.6%). Postoperatively, wound healing and phleboedema decongestion were observed mostly within 2 months. The VLU QoL questionnaire (39.3% response rate) showed improvement in QoL in activities, and psychological and symptom distress aspects. Conclusions:. Using LVB for chronic venous insufficiency showed an increase in the success rate of ulcer healing and decompression of the swollen limbs with durable results. Patient-reported outcome measures disclosed the potential benefits of LVB. Large-scale randomized controlled trials and pathophysiological studies are warranted to elucidate its efficacy.

Multivalvular endocarditis is a rare and potentially fatal complication that can occur in people who inject drugs. Currently, there are few cases that have been studied or reported in literature. A complication of this manifestation that worsens prognosis and treatment is the distribution of septic emboli throughout the body which highlights the dissemination of the infection. There are no specific guidelines on the treatment of multivalvular endocarditis, but its complexity can present challenges in administering medical and surgical treatment. In this case of a 37-year-old man with infective endocarditis of 3 valves, a comprehensive work-up found septic emboli in the lungs, kidneys, ribs, spine, and brain with ophthalmologic involvement that resulted in visual impairment. This case highlights important complications that can occur with septic emboli and management of these issues using a multidisciplinary approach including the treatment of substance use disorder.

Purpose: Brain metastases are common among adult patients with solid malignancies and are increasingly being treated with stereotactic radiosurgery (SRS). As more patients with brain metastases are becoming eligible for SRS, there is a need for practical review of patient selection and treatment considerations. Methods and Materials: Two patient cases were identified to use as the foundation for a discussion of a wide and representative range of management principles: (A) SRS alone for 5 to 15 lesions and (B) a large single metastasis to be treated with pre- or postoperative SRS. Patient selection, fractionation, prescription dose, treatment technique, and dose constraints are discussed. Literature relevant to these cases is summarized to provide a framework for treatment of similar patients. Results: Treatment of brain metastases with SRS requires many considerations including optimal patient selection, fractionation selection, and plan optimization. Conclusions: Case-based practice guidelines developed by the Radiosurgery Society provide a practical guide to the common scenarios noted above affecting patients with metastatic brain tumors.

Objective: To identify prognostically distinct phenotype clusters in transcatheter edge-to-edge repair (TEER) patients based on topological data analysis (TDA), which was never used to assess the heterogeneous TEER population. Patients and Methods: Patients who underwent TEER (June 2014-September 2020) at Mayo Clinic sites were identified from the institutional database. Thirteen variables were used for TDA. The topological network graph was created using the Python Scikit-TDA Kepler-Mapper package (v. 2.0.1), and clustering was performed at the graph level with Louvain’s modularity method. Kaplan-Meier survival analysis was used to assess the all-cause mortality of each cluster. Result: A total of 389 consecutive patients were included in the final analysis, and 2 major clusters were identified. The mean age was 80.3 ± 8.7 years; 256 (65.8%) were male. Fifty-five (14.5%) patients died during the mean follow-up duration (185 days). Kaplan-Meier analysis showed significant survival differences among the 2 clusters (hazard ratio, 2.70; 95% CI, 1.50-4.87; P=.0005). Cluster 1 (n=227) had moderate or increased residual mitral regurgitation (cluster 0 vs cluster 1: 19.4% vs 41.9%; P

Objective: To investigate the effect of minimally invasive cardiac surgery (MICS) on resource utilization, cost, and postoperative outcomes in patients undergoing left-heart valve operations. Methods: Data were retrospectively reviewed for patients undergoing single-valve surgery (eg, aortic valve replacement, mitral valve replacement, or mitral valve repair) at a single center from 2018 to 2021, stratified by surgical approach: MICS vs full sternotomy (FS). Baseline characteristics and postoperative outcomes were compared. Primary outcome was high resource utilization, defined as direct procedure cost higher than the third quartile or either postoperative LOS ≥7 days or 30-day readmission. Secondary outcomes were direct cost, length of stay, 30-day readmission, in-hospital and 30-day mortality, and major morbidity. Multiple regression analysis was conducted, controlling for baseline characteristics, operative approach, valve operation, and lead surgeon to assess high resource utilization. Results: MICS was correlated with a significantly lower rate of high resource utilization (MICS, 31.25% [n = 115] vs FS 61.29% [n = 76]; P

Objective: Sympathetic innervation plays a pivotal role in regulating cardiovascular health, and its dysregulation is implicated in a wide spectrum of cardiovascular diseases. This study seeks to evaluate the impact of denervation of the abdominal aorta on its morphology and wall homeostasis. Methods: Male and female Sprague-Dawley rats (N = 12), aged 3 months, underwent midline laparotomy for infrarenal aorta exposure. Chemical denervation was induced via a one-time topical application of 10% phenol (n = 6), whereas sham controls received phosphate-buffered saline (n = 6). Animals were allowed to recover and subsequently were sacrificed after 6 months for analysis encompassing morphology, histology, and immunohistochemistry. Results: At 6 months post-treatment, abdominal aortas subjected to phenol denervation still exhibited a significant reduction in nerve fiber density compared with sham controls. Denervated aortas demonstrated reduced intima-media thickness, increased elastin fragmentation, decreased expression of vascular smooth muscle proteins (α-SMA and MYH11), and elevated adventitial vascular density. Sex-stratified analyses revealed additional dimorphic responses, particularly in aortic collagen and medial cellular density in female animals. Conclusions: Single-timepoint phenol-based chemical denervation induces alterations in abdominal aortic morphology and vascular remodeling over a 6-month period. These findings underscore the potential of the sympathetic nervous system as a therapeutic target for aortic pathologies. Clinical Relevance: Aortic remodeling remains an important consideration in the pathogenesis of aortic disease, including occlusive, aneurysmal, and dissection disease states. The paucity of medical therapies for the treatment of aortic disease has driven considerable interest in elucidating the pathogenesis of these conditions; new therapeutic targets are critically needed. Here, we show significant remodeling after phenol-induced denervation with morphologic, histologic, and immunohistochemical features. Future investigations should integrate sympathetic dysfunction as a potential driver of pathologic aortic wall changes with additional consideration of the sympathetic nervous system as a therapeutic target.

Background:. Conditions that are treated by surgery constitute a significant portion of the global burden of disease. In low- and middle-income countries (LMICs), allocation of resources toward the most cost-effective surgical procedures (essential surgery) and care delivery platforms is critical. Nongovernmental organizations (NGOs) and the plastic surgeons who work with them play a significant role in plastic surgical outreach to LMICs. However, it is unknown whether their work aligns with existing global public health recommendations. Methods:. A previously established internet-based methodology was used to identify plastic surgical NGOs. Through direct correspondence with NGOs and publicly available data, plastic surgical NGOs were cataloged with respect to the subspecialty areas of plastic surgery performed, care delivery platforms, and geographic sites. These results were then compared with the existing global public health recommendations. Results:. A total of 96 NGOs met inclusion criteria. The most common subspecialty area was cleft surgery (80.3%), followed by pediatric plastic surgery (46.9%). No NGOs used a continuous care delivery platform. Instead, all NGOs used an intermittent model through short-term surgical missions, of which 62.8% used a nonrotating care model and returned to the same site(s) annually, whereas 37.2% used a rotating care model. Conclusions:. Most NGOs perform cleft surgery, an area considered essential surgery, and thus, collectively, the work of NGOs largely aligns with global public health priorities. However, there is room for improvement for both the types of procedures performed and the care delivery platforms to provide the most cost-effective and sustainable care.

The objective of this study was to compare the proximate, quality, and sensory attributes of Dorper sheep meat (Dorper), domestic commercial crossbred (DCC) and Australian commercial crossbred (ACC). A total of 60 untrimmed loins from the three sheep sources were purchased (20 sheep loins/source) and processed. The objective color, objective tenderness [Warner-Bratzler Shear Force (WBSF)], and proximate composition of the sheep meat were evaluated. A consumer panel and a trained sensory panel were also conducted to evaluate the sensory attributes. Dorper had greater (P = 0.04) carbohydrate content compared to DCC, but was not (P = 0.86) different from ACC. In addition, Dorper had the greatest WBSF value, followed by DCC, with ACC having the least WBSF out of the three (P < 0.0001). For the consumer panel, Dorper was rated to be less tender than ACC (P = 0.01), but was not different from DCC (P = 0.76). Dorper was also rated with lower flavor acceptability compared to DCC (P = 0.02), but was not different from ACC (P = 0.86). In addition, Dorper had the lowest overall acceptance rating by the consumers (P = 0.01). Trained sensory panel results followed the same trend as the consumer panel results which rated Dorper to be less tender than ACC (P = 0.002), but was not different from DCC (P = 0.10). Dorper was also rated with greater off-flavor intensity compared to DCC (P = 0.009), but was not different from ACC (P = 0.53). Finally, no differences were found for all other attributes evaluated among the sheep sources. The results indicated that consumers did not prefer Dorper over ACC and DCC. However, additional research with a more controlled environment is needed to shed light on the true palatability traits of Dorper.

Purpose The malignant transformation of cells can lead to aerobic glycolysis, an important form of metabolic reprogramming in colon cancer cells, which can cause the accumulation of lactate and accelerate the proliferation of tumor cells also enhance their chemotherapy drug resistance. The aim of this study was to investigate the possible molecular mechanisms responsible for the increased lactate expression in colon cancer. Methods Several bioinformatics methods, including differential analysis, gene ontology enrichment, univariate and multivariate Cox regression analysis were used to find the lactic acid–related gene carnitine palmitoyltransferase 2. We analyzed the relationship between carnitine palmitoyltransferase 2 and clinical features as well as immune microenvironment. To further explore the mechanism of carnitine palmitoyltransferase 2 in colon cancer, we performed methylation analysis and constructed a competitive endogenous RNA network, which was validated in cell lines and clinical specimens. Results We used bioinformatics to select the lactic acid–related gene carnitine palmitoyltransferase 2 and found low expression of carnitine palmitoyltransferase 2 was associated with poor prognosis in colon cancer. An inhibitory tumor microenvironment was created when carnitine palmitoyltransferase 2 expression was reduced, with decreased CD4 T cells, CD8 T cells, dendritic cells, and B cells but increased cancer-associated fibroblasts. Methylation analysis showed that the abnormal decrease in carnitine palmitoyltransferase 2 might be caused by hypermethylation. We constructed a network of SGMS1-AS1/microRNA-106a-5p/carnitine palmitoyltransferase 2 and verified their expression in cell lines and clinical specimens. Conclusion Our work revealed the possible mechanism of lactate accumulation in colon cancer and explored a new potential treatment for colon cancer by cutting off aerobic glycolysis in tumor cells.

Congenital right coronary artery-superior vena cava (RCA-SVC) fistula is rare and typically does not manifest any symptoms until the fifth decade of life. The present case demonstrates a 48-year-old woman who developed Sinus node dysfunction of unknown cause after Percutaneous coil embolization of the RCA-SVC fistula requiring permanent pacemaker. (Level of Difficulty: Intermediate.)

Type 2 diabetes is a major threat to human health in the 21st century. More than half a billion people may suffer from this pandemic disease in 2030, leading to a huge burden of cardiovascular complications. Recently, 2 novel antidiabetic agents, glucagon-like peptide 1 receptor agonists and sodium-glucose cotransporter 2 inhibitors, reduced cardiovascular complications in a number of randomized control trials. To integrate new information and to achieve a streamlined process for better patient care, a working group was appointed by the Taiwan Society of Cardiology to formulate a stepwise consensus pathway for these therapies to reduce cardiovascular events in patients with type 2 diabetes. This consensus pathway is complementary to clinical guidelines, acting as a reference to improve patient care.

Background: Peripheral arterial atheroprogression is increasingly prevalent, and is a risk factor for major limb amputations in individuals with risk factors such as diabetes. We previously demonstrated that bioactive lipids are significantly altered in arterial tissue of individuals with diabetes and advanced peripheral arterial disease. Methods: Here we evaluated whether sphingolipid ceramide 18:1/16:0 (C16) is a cellular regulator in endothelial cells and peripheral tibial arterial tissue in individuals with diabetes. Results: We observed that C16 is the single most elevated ceramide in peripheral arterial tissue from below the knee in individuals with diabetes (11% increase, P < .05). C16 content in tibial arterial tissue positively correlates with sphingomyelin (SPM) content in patients with and without diabetes (r2 = 0.5, P < .005; r2 = 0.17, P < .05; respectively). Tibial arteries of individuals with diabetes demonstrated no difference in CERS6 expression (encoding ceramide synthase 6; the predominate ceramide synthesis enzyme), but higher SMPD expression (encoding sphingomyelin phosphodiesterase that catalyzes ceramide synthesis from sphingomyelins; P < .05). SMPD4, but not SMPD2, was particularly elevated in maximally diseased (Max) tibial arterial segments (P < .05). In vitro, exogenous C16 caused endothelial cells (HUVECs) to have decreased proliferation (P < .03), increased apoptosis (P < .003), and decreased autophagy (P < .008). Selective knockdown of SMPD2 and SMPD4 decreased native production of C16 (P < .01 and P < .001, respectively), but only knockdown of SMPD4 rescued cellular proliferation (P < .005) following exogenous supplementation with C16. Conclusions: Our findings suggest that C16 is a tissue biomarker for peripheral arterial disease severity in the setting of diabetes, and can impact endothelial cell viability and function. Clinical relevance: Peripheral arterial disease and its end-stage manifestation known as chronic limb-threatening ischemia (CLTI) represent ongoing prevalent and intricate medical challenges. Individuals with diabetes have a heightened risk of developing CLTI and experiencing its complications, including wounds, ulcers, and major amputations. In the present study, we conducted a comprehensive examination of the molecular lipid composition within arterial segments from individuals with CLTI, and with and without diabetes. Our investigations unveiled a striking revelation: the sphingolipid ceramide 18:1/16:0 emerged as the predominant ceramide species that was significantly elevated in the peripheral arterial intima below the knee in patients with diabetes. Moreover, this heightened ceramide presence is associated with a marked impairment of endothelial cell function and viability. Additionally, our study revealed a concurrent elevation in the expression of sphingomyelin phosphodiesterases, enzymes responsible for catalyzing ceramide synthesis from sphingomyelins, within maximally diseased arterial segments. These findings underscore the pivotal role of ceramides and their biosynthesis enzymes in the context of CLTI, offering new insights into potential therapeutic avenues for managing this challenging disease process.

Introduction: The first COVID-19 cases occurred in the US in January of 2020, leading to the implementation of shelter in place. This study seeks to define the impact of shelter in place on the epidemiology of pediatric trauma. Methods: We examined pediatric trauma admissions at 5 Level 1 and 1 Level 2 US pediatric trauma centers between January 1 and June 30, 2017–2020. Demographic and injury data were compared between pre– and post–shelter in place patient cohorts. Results: A total of 8772 pediatric trauma activations were reviewed. There was a 13% decrease in trauma volume in 2020, with a nadir at 16 days following implementation of shelter in place. Injury severity scores were higher in the post–shelter in place cohort. The incidence of nonmotorized vehicle accidents and gunshot wounds increased in the post–shelter in place cohort. Conclusion: We found an overall decrease in pediatric trauma volume following shelter in place. However, injuries tended to be more severe. Our findings help inform targeted injury prevention campaigns during future pandemics.

Category: Midfoot/Forefoot Introduction/Purpose: Nonunion is one of the most common and devastating complications following midfoot joint arthrodesis. Many different types of bone grafts and bone substitutes have been used to promote osseous fusion. However, there is no consensus on the gold standard bone grafting material and whether biologic materials should be used alone or in combination. The purpose of this study is to investigate the efficiency of highly porous β-tricalcium phosphate (β-TCP) with Bone Marrow Aspirate Concentrate (BMAC) in midfoot joint arthrodesis. Methods: This retrospective comparative study included patients who underwent midfoot joint arthrodesis using compression screws from January 2014 to May 2019. A total of 44 patients (46 feet) including 89 joints were included in this study. The cohort was then stratified into two groups: 25 patients (26 feet) in arthrodesis with highly porous β-TCP and BMAC (group A) and 19 patients (20 feet) in arthrodesis without highly porous β-TCP and BMAC (group B). The osseous union rate was compared between the two groups. Demographic and operative data including age, sex, body mass index (BMI), smoking, etiology of arthritis, comorbidities such as diabetes mellitus and rheumatoid arthritis, number of joints fixed, use of bone graft or bone substitute, and postoperative midfoot anatomic alignment in the two groups were compared. Results: There was a significant difference in the union rate between the two groups: 91.5 % (43 out of 47 joints) in arthrodesis with highly porous β-TCP and BMAC (group A) and 76.2 % (32 out of 42 joints) in arthrodesis without highly porous β-TCP and BMAC (group B) (P = 0.048). During the follow-up period, a total of four postoperative complications were reported in this study. In group A, two patients developed hardware irritation, and all of them underwent removal of hardware procedure. In group B, one patient had a superficial wound infection, which was resolved completely without further treatment. The other patient in group B developed a deep wound infection with dehiscence, and it was managed with irrigation and debridement followed by vacuum assisted wound closure therapy. Conclusion: This study investigated the efficiency of highly porous β-TCP and BMAC to promote bony healing in midfoot joint arthrodesis. A significantly higher union rate was shown when arthrodesis was performed with highly porous β-TCP and BMAC compared to arthrodesis without them, suggesting that highly porous β-TCP and BMAC can be a viable and effective adjunct to the fixation in midfoot joint arthrodesis.

Category: Midfoot/Forefoot Introduction/Purpose: There is still a controversy regarding the most optimal fixation instruments and bone graft materials for midfoot joint arthrodesis. We present the results of midfoot joint arthrodesis using compression plate highly porous β-tricalcium phosphate (β-TCP) and bone marrow aspirate concentrate (BMAC). Methods: We performed a retrospective review of patients undergoing midfoot joint arthrodesis using compression plate with lag screw augmenting with highly porous β - tricalcium phosphate (β - TCP) and bone marrow aspirate concentrate (BMAC) from January 2014 to May 2019. The radiographic bony union rate was investigated. Postoperative complications and reoperations were also noted. A total of 36 patients (37 feet) including 75 joints were available in this study. Results: A high bony union rate was achieved as of 97.3% in 73 out of 75 joints. Nonunion was seen in two patients including two joints: one for 1st TMT joint and the other for medial NC joint. There was no delayed union in this study. Time to radiographic union was 10.5 +- 1.9 (range, 7-15) weeks. A total of five postoperative complications were noted. All of them were related to hardware irritation, and all five patients underwent removal of hardware procedure. There was no major complication such as infection during the follow-up period. Of the two nonunion patients, only one with medial NC joint nonunion underwent a revision arthrodesis surgery. Conclusion: Based on our results, the fixation construct of compression plate with lag screw augmenting with highly porous β - tricalcium phosphate (β - TCP) and bone marrow aspirate concentrate (BMAC) is safe and effective for midfoot joint arthrodesis with an excellent union rate and a low complication rate.

Introduction: The oncology clinical trial recruitment process is time, labor, and resource intensive, and poor accrual rates are common. We describe the VA Connecticut Cancer Center experience of implementing a standardized, universal prescreening protocol and its impact on thoracic oncology research recruitment. Methods: Research coordinators prescreened potentially eligible patients with confirmed or suspected cancer from multiple clinical sources and entered relevant patient and research study information into a centralized electronic database. The database provided real-time lists of potential studies for each patient. This enabled the research team to alert the patient's oncologist in advance of clinic visits and to prepare documents needed for enrollment. Clinicians could ensure sufficient time and attention in clinic to the informed consent process, therefore maximizing enrollment opportunities. Patients were also monitored on waitlists for future studies. Results: From March 2017 to December 2020, a total of 1518 patients with lung nodules and suspected or confirmed lung cancers were prescreened. Of these, 379 patients were enrolled to a study, 103 patients declined participation, and 639 were monitored for future studies. Our prescreening protocol identified all new patients with lung cancer who were ultimately added to the cancer registry. We found a substantial increase in study enrollment after prescreening implementation. Conclusions: Universal prescreening was associated with improved patient enrollment to thoracic oncology studies. The protocol was integral in our VA becoming the top accruing VA site for National Cancer Institute’s National Clinical Trials Network studies for 2019 to 2021.

Background:. Most botulinum toxin A (BoNT/A) products contain unnecessary bacterial components that increase the risk of developing neutralizing antibodies (nAbs). Reports of secondary nonresponse and treatment failures (STF) due to nAbs have accompanied a surge in new BoNT/A products. Methods:. To formulate recommendations on managing toxin resistance, we reviewed the evidence on BoNT/A-associated immunogenicity and evaluated Asian physicians' current BoNT/A practices, knowledge, and real-world experiences, as provided by survey outcomes conducted with 128 Asian experts (regular botulinum toxin injectors). Results:. Most doctors believe STF occurs, some patients exhibit partial symptoms, and impurities (eg, complexing proteins) in BoNT/A preparations risk STF. Bioassays that distinguish non-nAbs from nAbs that hinder toxin function remain unavailable to most doctors, though most would perform testing if given the option. Doctors in the Asia-Pacific region have differing strategies for managing STF, depending on the availability of alternatives or tests. They recommended switching to a highly-purified formulation free of complexing proteins and other impurities to lower the risk of immunogenicity, or offering treatment holidays of 2 -2.5 years. They suggested restarting treatment with the same highly purified formulation, especially for repeated treatments, large-dose injections, and younger patients who will accumulate higher lifetime doses, so as to minimize immunogenic risks and preserve long-term treatment outcomes. Importantly, doctors should always initiate patients on pure formulations rather than switching to these only after resistance develops. Conclusion:. Choosing highly purified BoNT/A products at treatment initiation enhances long-term efficacy and patient satisfaction while minimizing the risk of immune activation and nAb formation.

Purpose: Single agent PD-1 inhibitors have yielded durable responses in a minority of gastroesophageal cancers. Radiation therapy has been recognized to promote antitumor immune responses and may synergize with anti-PD-1 agents. We sought to evaluate if combining palliative radiation therapy with pembrolizumab can augment antitumor immune responses in gastroesophageal cancer. Methods and Materials: Patients had metastatic gastroesophageal cancer with indication for palliative radiation therapy with ≥2 disease sites outside of the radiation field assessable for abscopal response and biopsies for laboratory correlative analyses. Palliative radiation was delivered to a dose of 30 Gy over 10 fractions. Pembrolizumab, 200 mg, was administered concurrently intravenously every 3 weeks until disease progression, unacceptable toxicity, or study withdrawal, for up to 2 years. Endpoints included PD-L1 expression in pre- and posttreatment biopsies and abscopal objective response rate per Response Evaluation Criteria in Solid Tumors. Results: Of 14 enrolled patients, the objective response rate was 28.6% (95% confidence interval, 8.4%-58.1%), and the median duration of response was not reached (95% confidence interval, 6.9-NR months). Overall, 2 patients had treatment-related grade 3 to 4 adverse events with no grade 5 events. One patient discontinued therapy due to grade 4 colitis. We did not observe an association between radiation and abscopal changes in PD-L1 expression via assessment of an analogous PD-L1 Combined Positive Score, Tumor Proportion Score, Mononuclear Immune Cell Density Score, or proportion of PD-L1-expressing immune cells between pre- and posttreatment tumor biopsies. Conclusions: Combining palliative radiation therapy and pembrolizumab provided promising durable responses in this patient population but we were unable to definitively distinguish abscopal biologic changes. Biomarker analyses beyond PD-L1 expression are needed to better understand putative mechanisms and identify patients who will benefit from this approach.

Pyomyositis is a bacterial infection occurring mainly in skeletal muscles. It is most commonly caused by Staphylococcus aureus with initial symptoms including muscle pain, swelling, and site tenderness. When available, the most accurate technique to determine the extent and the specific location of disease is the magnetic resonance imaging. Successful management includes early recognition, timely surgical debridement or drainage, and appropriate antibiotic therapy. This case report describes a case of Mycobacterium fortuitum pyomyositis in an elderly male associated with challenges of successful diagnosis.

Category: Midfoot/Forefoot; Bunion Introduction/Purpose: The most common joint preparation techniques mentioned in literature for 1st metatarsophalangeal (MTP) joint arthrodesis are 'cup and cone' and 'flat-cuts'. A third option of an 'in-situ' technique, has rarely been studied. This study compares the clinical, radiographic, and patients-reported outcomes of 'in-situ' joint preparation with a traditional 1st MTP joint preparation technique. Methods: The 'in-situ' technique utilizes the same dorsal surgical incision as traditional techniques. Cartilage and osteophyte removal are carried out using standard techniques without the use of specific reamers or a sagittal saw. The arthrodesis is performed in-situ with the similar freedom of joint positioning as the cup and cone technique, and traditional fixation constructs are applied. In this study, A retrospective chart review was performed for patients who underwent 1st MTP joint arthrodesis between January 2015 and December 2019. The complication, revision and non-union rates were examined in a multivariable logistic regression model. Patient reported outcome were analyzed in a repeated measures general linear model. Analysis of variance and Receiver Operating Characteristic were used to assess radiographic measurements. Results: Total of 388 1st MTP joint arthrodesis cases were included. Overall, 262 'Flat-Cuts' and 126 'In-Situ' cases were analyzed. Mean follow-up time was 292 days (median 174, SD 305). Joint-preparation technique did not have statistically significant impact on union rates (p=0.311) or revision rates (p=0.898). Diabetes-Mellitus was the most powerful predictor of non-union (p

Category: Midfoot/Forefoot; Bunion Introduction/Purpose: The most common indications for revision of 1st Metatarsophalangeal (MTP) joint surgery are symptomatic failures of prior fusion, failed hallux valgus correction, and failed MTP arthroplasty implants. The outcome of revision 1st MTP fusion has rarely been studied. The purpose of this study was to compare the clinical, radiographic, and patient-reported outcomes of revision MTP fusion for different indications. Methods: A retrospective chart review was performed for patients who underwent revision 1st MTP fusion between January 2015 and December 2019 in a single-center, by 4 fellowship-trained foot and ankle surgeons. The complication, revision, and non- union rates as well as VAS and PROMIS scores and pre-operative and post-operative radiographs were analyzed and compared between the different indication groups. Univariate and multivariate analysis and logistic regression models were used to obtain odds ratio of the explanatory variables for outcome measures. Results: A total of 79 cases of revision MTP fusion were included. Thirty-eight cases of hallux valgus corrections salvage, 22 failed MTP arthroplasty implants, 6 failed polyvinyl alcohol hydrogel implants, 13 prior MTP fusion non-unions. The mean follow-up time was 350 days (Median 226, SD 306). Seven cases (8.9%) required structural iliac-crest bone graft during the revision. Seven cases (8.9%) required allograft augmentation. The overall complication rate was 40.7%. Fifteen patients (18.5%) were classified as Clavien-Dindo grade 3, which represents a complication that may require a revision surgery (i.e. non-union, deep infection, loss of correction). Eventually, 7 cases (8.9%) underwent further revision surgery. The logistic regression model demonstrated that indication for revision was not significantly related to union rate (p=0.280). Visual-Analogue-Scale significantly improved at 6 weeks, 3 months, and at last follow-up in all indications for revision (p=0.001). PROMIS-10 Physical and PROMIS-10 Mental did not change significantly during follow-up (p=0.860, p=0.589). Conclusion: Treatment of 1st MTP joint surgery failures is a clinical challenge in orthopaedic surgery. In our study, revision of 1st MTP joint surgery with MTP fusion had higher non-union rates and higher overall complication rates compared to primary 1st MTP fusion. Nevertheless, revision rates remained comparable to primary 1st MTP fusion. Complication rates and patient- reported outcomes were similar between the different indications for revision groups. Visual-analogue-scale improved significantly during follow-up in all groups. Diabetes mellitus had a significant impact on non-union rates and overall complication rates.

Background:. Phalangeal and metacarpal fractures are the second and third most common upper extremity fractures after distal radius fractures with varying methods of fixation techniques. Intramedullary screw fixation is an increasingly preferred method of fixation. Benefits include early range of motion, faster recovery, limited dissection, and reduced complications. Improper technique, which is readily avoidable, can lead to suboptimal results. Methods:. A review of recent literature on current techniques aims to summarize the biomechanics of intramedullary screw fixation and outline appropriate technique of placing headless compression screws for metacarpal and phalangeal fractures. Results:. We discuss through images and videos the indications, preoperative workup, and technical pearls and pitfalls to encourage surgeons to add this technique to their armamentarium and improve outcomes. Conclusions:. intrameduallry screw fixation is a powerful option for metacarpal and phalanx fixation that allows rigid stability, enabling early return of function with excellent rates of union and total active motion. With knowledge of technical pearls presented in this article, common mistakes can be avoided to improve efficiency of screw placement and optimize patient outcomes.

Purpose: NRG Oncology's RTOG 0933 demonstrated benefits to memory preservation after hippocampal avoidant whole-brain radiation therapy (HA-WBRT), the avoidance of radiation dose to the hippocampus (using intensity modulated radiation planning and delivery techniques) during WBRT, supporting the hypothesis of hippocampal radiosensitivity and associated memory specificity. However, some patients demonstrated cognitive decline, suggesting mechanisms outside hippocampal radiosensitivity play a role. White matter injury (WMI) has been implicated in radiation therapy–induced neurocognitive decline. This secondary analysis explored the relationship between pretreatment WMI and memory after HA-WBRT. Methods and Materials: Volumetric analysis of metastatic disease burden and disease-unrelated WMI was conducted on the pretreatment magnetic resonance image. Correlational analyses were performed examining the relationship between pretreatment WMI and Hopkins Verbal Learning Test-Revised (HVLT-R) outcomes at baseline and 4 months after HA-WBRT. Results: In the study, 113 patients received HA-WBRT. Of 113 patients, 33 underwent pretreatment and 4-month posttreatment HVLT testing and pretreatment postcontrast volumetric T1 and axial T2/fluid-attenuated inversion recovery magnetic resonance imaging. Correlation was found between larger volumes of pretreatment WMI and decline in HVLT-R recognition (r = 0.54, P

Category: Other; Bunion; Midfoot/Forefoot Introduction/Purpose: There is no standard guideline for prescription opioids for postoperative pain management following outpatient foot and ankle surgery. Multiple previous studies demonstrated that opioids were overprescribed. The purpose of this study was to prospectively investigate opioid consumption using multimodal analgesia regimen after two of the most common forefoot surgeries: isolated hallux valgus correction or 1st metatarsophalangeal (MTP) joint arthrodesis. Methods: We prospectively investigated opioid prescription and consumption of total 21 patients who underwent isolated hallux valgus correction with distal soft tissue procedure and proximal first metatarsal crescentic osteotomy or 1st MTP joint arthrodesis. Postoperative pain was managed using multimodal analgesia including oxycodone, ibuprofen, acetaminophen, and regional ankle block. Patients were instructed to take 5mg of oxycodone every 4 hours as needed, and 600 mg of ibuprofen as well as 1,000 mg of acetaminophen every 8 hours regularly. The number of pills patients consumed for oxycodone was recorded at postoperative follow-up at 1-week, 2-week, 4-week, 8-week, and 12-week. Subgroup analysis was performed to evaluate opioid consumption according to the prescription type: Only oxycodone was prescribed in group A while oxycodone as well as prescription strength ibuprofen and acetaminophen were prescribed in group B. Another subgroup analysis in opioid consumption was performed based on the quantity of opioid prescription and procedure type. Results: The overall mean opioid consumption in 12 weeks of the postoperative period was 16.2 pills per patient with an average of 37.3 pills prescribed. Lower opioid consumption was noted in group B when prescription ibuprofen and acetaminophen were prescribed compared to group A when patients took over-the-counter (OTC) ibuprofen and acetaminophen: 9.0 pills vs 24.1 pills, respectively (P = 0.036). There was a trend showing higher opioid consumption in patients prescribed greater than 30 pills of oxycodone compared to less than or equal to 30 pills: 22.0 pills vs 9.8 pills, respectively (P = 0.099). No significant difference was found in opioid consumption according to the procedure type: 15.8 pills in hallux valgus correction vs 16.5 pills in 1st MTP joint arthrodesis (P = 0.750). Conclusion: This study showed that on the average, patients took 16.2 pills out of 37.3 pills of the prescribed oxycodone after isolated hallux valgus correction or 1st MTP joint arthrodesis using our multimodal analgesia regimen. Patients who were prescribed prescription strength ibuprofen and acetaminophen consumed opioid significantly less than those who took the OTC strength. No significant difference was noted in opioid consumption between isolated hallux valgus correction and 1st MTP joint arthrodesis.

Category: Midfoot/Forefoot Introduction/Purpose: Polyvinyl Alcohol Hydrogel (PAH) hemiarthroplasty has gained popularity in the operative management of symptomatic hallux rigidus since its introduction to the US in July 2016. Despite encouraging initial results, any implant has the potential for complications that may not become apparent until it is in widespread use. Also, the series of publications supporting the effectiveness of PAH have come from a limited group of institutions and surgeons which creates an opportunity for observational bias. Other complications or unsatisfactory outcomes may be under-reported, such as those experienced in community centers due to the challenges in publishing lower volume work. In order to look at a broader range of potential complications, we reviewed the United States Food and Drug Administration’s (FDA) database and compared with published literature. Methods: The Manufacturer and User Facility Device Experience (MAUDE) database of the US Food and Drug Administration (FDA) was retrospectively reviewed between July 2016 and October 2019 using the assigned product code: PNW for the PAH implant. All the reported adverse events, implant-related complications, and secondary procedures were analyzed. Results: A total of 49 events have been reported to this voluntary database over the past 3 years while over 22,000 Cartiva devices have been implanted. Implant subsidence was the most common with 16 reported instances. Fragmentation of the device was observed in nine and four reports were related to infection in which two were deep infections needing antibiotic spacers. Bone erosion managed by grafting was documented in three reports and foreign body reaction was noted in one. Persistent pain and swelling were common presentations. Thirty-five of 49 reported events required additional operative procedures performed at a mean interval of 4.75 months following the index procedure while four more were awaiting further surgery. Conversion to fusion was the most common procedure, featured in 10 reports. Conclusion:: The analysis of the MAUDE database disclosed certain device-related dysfunctions that have been under-reported in the published literature. Also, complications such as fragmentation, bone erosion and foreign body reaction have not been previously described. Awareness of these details will assist in decision-making and quality control. Due to the voluntary nature of reporting, the true incidence of each complication is unknown with the above data representing a baseline. Nonetheless, the MAUDE database serves as an illuminating source of information which would further be strengthened by a more robust and mandatory reporting of device-related complications.

Summary:. Implant-based breast reconstruction is a safe and effective option associated with high patient satisfaction. Techniques have evolved significantly over the past several decades, characterized mostly by a reduction in the number of stages and time required to complete reconstruction, with maximal preservation of native breast elements. Nevertheless, both old and new techniques of implant-based breast reconstruction have a role depending on the specific clinical scenario, and thus plastic surgeons should be well versed in the full spectrum of options. This article reviews the key considerations underlying decision-making in implant-based breast reconstruction and the most effective techniques, with a focus on optimizing safety and efficiency.

A positive fluid balance has been found to be deleterious in critically ill patients; however, the impact of early fluid balance, particularly on long-term outcomes, in critically ill patients with cancer remains unclear. We performed this retrospective study at a tertiary-care referral hospital with 1500 beds and 6 intensive care units (ICUs) in central Taiwan, and 942 patients with cancer admitted to ICUs during 2013 to 2016 were enrolled. The primary outcome was 1-year mortality. Cancer-related data were obtained from the cancer registry, and data during ICU admissions were retrieved from the electronic medical records. The association between fluid balance, which was represented by median and interquartile range, and 1-year mortality was determined by calculating the hazard ratio (HR) with 95% confidence interval (CI) using a multivariable Cox proportional hazards regression model. The in-hospital mortality rate was 22.9% (216 of 942), and the mortality within 1 year after the index ICU admission was 38.7% (365 of 942). Compared to survivors, nonsurvivors tended to have a higher Acute Physiology and Chronic Health Evaluation II score (24.1 ± 6.9 vs 20.5 ± 6.2, P < .01), a higher age (65.0 ± 14.4 vs 61.3 ± 14.3, P < .01), a higher serum creatinine (1.5 ± 1.3 vs 1.0 ± 1.0, P < .01), and a higher cumulative day 1 to 4 fluid balance (2669, 955-5005 vs 4103, 1268-7215 mL, P < .01). Multivariable Cox proportional hazards regression analysis found that cumulative day-4 fluid balance was independently associated with 1-year mortality (adj HR 1.227, 95% CI: 1.132-1.329). A positive day 1 to 4 cumulative fluid balance was associated with shorter 1-year survival in critically ill patients with cancer. Further studies are needed to validate this association.

Progressive thoracolumbar hyperkyphosis (aka hunchbacked) with a sagittal imbalance in an osteoporotic compression fracture might warrant surgical correction when conservative treatment fails. A 70-year-old woman presented with an L1 osteoporotic compression fracture after an L1 vertebroplasty and a short-segment (T12-L2) pedicle screw fixation. Because of the osteoporosis, the pedicle screws had loosened and a new L4 compression fracture occurred after the surgery. The author used the cortical bone trajectory screw technique for a long-segment posterior fixation after an anterior vertebral column resection. The outcome was good at the one-year follow-up. This technique provided a thoracolumbar Cobb angle correction of 20° and a sagittal vertical axis correction from 8.3 cm to 2.5 cm. This was the first reported case using the long-segment cortical bone trajectory screw technique to treat an osteoporotic compression fracture in progressive thoracolumbar hyperkyphosis. Keywords: Cortical bone trajectory screw, Osteoporotic compression fracture, Thoracolumbar hyperkyphosis

Atrial fibrillation (AF) is the most common sustained arrhythmia, causing a 2-fold increase in mortality and a 5-fold increase in stroke. The Asian population is rapidly aging, and in 2050, the estimated population with AF will reach 72 million, of whom 2.9 million may suffer from AF-associated stroke. Therefore, stroke prevention in AF is an urgent issue in Asia. Many innovative advances in the management of AF-associated stroke have emerged recently, including new scoring systems for predicting stroke and bleeding risks, the development of non-vitamin K antagonist oral anticoagulants (NOACs), knowledge of their special benefits in Asians, and new techniques. The Asia Pacific Heart Rhythm Society (APHRS) aimed to update the available information, and appointed the Practice Guideline sub-committee to write a consensus statement regarding stroke prevention in AF. The Practice Guidelines sub-committee members comprehensively reviewed updated information on stroke prevention in AF, emphasizing data on NOACs from the Asia Pacific region, and summarized them in this 2017 Consensus of the Asia Pacific Heart Rhythm Society on Stroke Prevention in AF. This consensus includes details of the updated recommendations, along with their background and rationale, focusing on data from the Asia Pacific region. We hope this consensus can be a practical tool for cardiologists, neurologists, geriatricians, and general practitioners in this region. We fully realize that there are gaps, unaddressed questions, and many areas of uncertainty and debate in the current knowledge of AF, and the physician׳s decision remains the most important factor in the management of AF.

Purpose: To validate a conceptual short-form health literacy 12 items questionnaire (HL-SF12) in patient populations. Methods: A cross-sectional study was conducted via a convenient sample of 403 patients from three departments of a community general hospital in the northern Taiwan. Patients’ health literacy was assessed with a validated HL-SF12, derived from the full scale, the European Health Literacy Survey Questionnaire (HLS-EU-Q), as well as a single-item from Chew’s Set of Brief Health Literacy Question. A reference population in Northern Taiwan (n=928) via the HLS-EU-Q in 2013–2014 was used as a reference to compare the health literacy between that of the general public and the patients. Data was analyzed by confirmatory factor analysis (CFA), internal consistency analysis, correlation analysis, and linear regression models. Results: Patients’ health literacy assessed with the HL-SF12 was shown with high internal consistency (Cronbach α=.87), and moderately correlated with the single-item from Chew's Set of Brief Health Literacy Question, with satisfactory item-scale convergent validity (item-scale correlation ≥ .40), without floor/ceiling effect, and with satisfactory goodness of fit indices of the three-factor construct model for most of the patients. Their health literacy was significantly positively associated with female gender, higher income, and more often watching health-related TV programs. On the other hands, patients were reported with significantly higher healthcare health literacy than the general public, but not in general health literacy, disease prevention health literacy, or health promotion health literacy. Conclusion: The comprehensive HL-SF12 was a valid and easy to use tool for assessing patients’ health literacy in the hospitals to facilitate healthcare providers in enhancing patients’ health literacy and healthcare qualities.

In the United States, approximately 2000 stingray injuries occur annually. The majority of reports on stingray injuries to the foot and ankle reflect acute injuries. Delayed presentation after stingray injury to the foot and ankle has not been reported. We present a case of a 29-year-old female who sustained a stingray injury to the left plantar medial hindfoot 14 months prior to presenting to our clinic with new-onset posteromedial ankle redness and swelling along the tarsal tunnel. Magnetic resonance imaging (MRI) revealed multiple linear foreign bodies at the quadratus plantae and tarsal tunnel. The patient underwent operative exploration with removal of multiple retained stingray spines. At her most recent follow-up at 3 months, she was able to resume her usual activities. Level of Evidence: Level V, case report.

Background. Cutaneous squamous cell carcinoma is a common type of skin cancer, with aggressive metastatic or locally advanced disease representing an uncommon minority of presentations. Emerging data have supported the Food and Drug Administration approval of the anti-PD1 human monoclonal antibody cemiplimab in select patients with advanced disease. However, there is limited data regarding durability of effect and generalizability of anti-PD1 effectiveness across therapies. Additionally, information regarding applicability of these regimens to the rare spindle cell variant and to central nervous system metastases for cutaneous squamous cell carcinoma is unfortunately limited. Case Presentation . A 72-year-old gentleman presented with facial neurological deficits and a dermal nodule and was diagnosed with spindle cell squamous cell carcinoma with perineural invasion. His course was notable for early intracranial metastasis with progressive neurological deficits despite recurrent radiation therapy with intermittent response. When progressive left-sided weakness prompted imaging evaluation that was concerning for disease recurrence after exhaustion of radiation therapy options, the patient was started on systemic therapy with the anti-PD-1 monoclonal antibody treatment prior to the approval of cemiplimab. Pembrolizumab was chosen due to the fact that the patient was ineligible for clinical trials and for its every 21-day dosing. With this treatment, he has achieved a durable clinical response, resulting in near resolution of neurological deficits and more than a year of progression-free survival to date, despite aggressive intracranial disease. Conclusions. This case suggests that anti-PD-1 therapy with pembrolizumab may represent an effective and well-tolerated treatment for patients with metastatic spindle cell squamous cell carcinoma including patients with metastatic disease to the central nervous system.

Purpose: The purpose of this study was to compare leukemia-free survival (LFS) and other clinical outcomes in patients with acute myelogenous leukemia who underwent a myeloablative allogeneic stem cell transplant with and without total body irradiation (TBI). Methods and materials: Adult patients with acute myelogenous leukemia undergoing myeloablative allogeneic stem cell transplant at Duke University Medical Center between 1995 and 2012 were included. The primary endpoint was LFS. Secondary outcomes included overall survival (OS), nonrelapse mortality, and the risk of pulmonary toxicity. Kaplan-Meier survival estimates and Cox proportional hazards multivariate analyses were performed. Results: A total of 206 patients were evaluated: 90 received TBI-based conditioning regimens and 116 received chemotherapy alone. Median follow-up was 36 months. For all patients, 2-year LFS and OS were 36% (95% confidence interval [CI], 29-43) and 39% (95% CI, 32-46), respectively. After adjusting for known prognostic factors using a multivariate analysis, TBI was associated with improved LFS (hazard ratio: 0.63; 95% CI: 0.44-0.91) and OS (hazard ratio: 0.63; 95% CI, 0.43-0.91). There was no difference in nonrelapse mortality between cohorts, but pulmonary toxicity was significantly more common with TBI (2-year incidence 42% vs 12%, P < .001). High-grade pulmonary toxicity predominated with both conditioning strategies (70% and 93% of cases were grade 3-5 with TBI and chemotherapy alone, respectively). Conclusions: TBI-based regimens were associated with superior LFS and OS but at the cost of increased pulmonary toxicity.

Background:. Robin sequence is defined by the clinical triad of micrognathia, glossoptosis, and upper airway obstruction, and is frequently associated with cleft palate and failure to thrive. Though the efficacy of certain surgical interventions to relieve airway obstruction has been well established, algorithms dictating decision making and perioperative protocols are poorly defined. Methods:. A 22-question survey was sent via e-mail to members of the American Cleft Palate-Craniofacial Association and International Society of Craniofacial Surgeons. Questions were related to surgeon experience in treating neonates with Robin sequence, and specific perioperative protocols. Results:. One hundred fifty-one responses were collected. Most respondents were surgeons practicing in North America(82.8%), in a university hospital setting (81.5%) and had completed a fellowship in pediatric plastic surgery or craniofacial surgery (76.2%). Preoperative protocols varied widely by years in training and location of practice. Although 78.8% of respondents always performed direct laryngoscopy, only 49.7% of respondents routinely obtained preoperative polysomnography. Mandibular distraction osteogenesis was the most common primary surgical airway intervention reported by 74.2%, with only 12.6% primarily utilizing tongue-lip adhesion. Slightly less than half of respondents ever performed tongue-lip adhesion. Operative selection was influenced by surgeon experience, with 80% of those in practice 0–5 years primarily utilizing mandibular distraction, compared with 56% of respondents in practice >15 years. Conclusions:. This study documents wide variations in preoperative, operative, and postoperative protocols for the surgical airway management of neonates with severe Robin sequence. These results underscore the need to acquire more objective data, to compare different protocols and outcome measures.

Summary:. A 3-dimensional, multi-layered approach combining modalities targeting different manifestations is recommended for achieving optimal esthetic outcomes. To date, studies reporting same-day treatment with dermal fillers and botulinum toxin have not been published. This article documents the practical use of a single-visit, pan-facial multimodal approach in addressing the varying esthetic needs of 8 Asian adults. The case series included male or female patients of varying age and degrees of facial fat, who received combination treatment with calcium hydroxylapatite filler, polydensified hyaluronic acid filler, and incobotulinumtoxin A in a single visit in August 2016 at a treatment center in Taiwan. Treatments were individualized based on the needs of each patient, according to guideline recommendations. The agents, with distinctive rheological properties indicated for different purposes, were applied sequentially across different facial tissue planes within a single visit. Patients were monitored for development of side effects after treatment. Photographs taken before treatment and 2 weeks after treatment were evaluated by the treating physicians. For all patients, treatment produced substantial improvements in all treated facial areas. Inherent morphological deficiencies in younger patients were addressed, age-related changes in older patients were corrected, and facial sexual dimorphism was enhanced in male and female patients. No major side effects occurred after treatment. This case series showcases the real-life implementation of a flexible, single-visit, multimodal approach that can be adapted for a variety of indications.

Intravenous therapy is a common practice among many specialties. Intravenous therapy extravasation is a potential complication to such therapy. Hospitals without a dedicated wound care team trained in these interventions will often default to plastic surgical consultation, making an understanding of available interventions essential to the initial evaluation and management of these injuries. The goal of this article was to provide plastic surgeons and health care providers with a general overview of the acute management of intravenous infiltration and extravasation injuries. Though the decision for surgical versus nonsurgical management is often a clear one for plastic surgeons, local interventions, and therapies are often indicated and under-utilized in the immediate postinfiltration period. Thorough knowledge of these interventions should be a basic requirement in the armamentarium of plastic surgery consultants.

A 61-year-old man with history of coronary artery disease and coronary artery bypass graft presented with chest pain. A left heart catheterization showed a new kink in the body of his left internal mammary artery to left anterior descending artery graft. The kink improved with inspiration, which suggests re-assessment of similar cases should be done during deep inspiration. (Level of Difficulty: Intermediate.)
