Published: February 2023

Background

Determining the resectability of pancreatic cancer with vascular involvement on preoperative computed tomography imaging remains challenging, especially following preoperative chemotherapy and chemoradiotherapy. Intraoperative ultrasound (IOUS) may provide real-time additional information, but prospective multicenter series confirming its value are lacking.

Patients and Methods

This prospective multicenter study included patients undergoing surgical exploration for pancreatic cancer with vascular involvement. All patients underwent IOUS at the start of explorative laparotomy. Primary outcomes were resectability status as defined by the National Comprehensive Cancer Network and the extent of vascular involvement.

Results

Overall, 85 patients were included, of whom 74 (87%) were post preoperative chemotherapy, and mostly following FOLFIRINOX regimen (n = 57; 76%). On the basis of preoperative imaging, 34 (40%) patients were staged as resectable (RPC), 32 (38%) borderline resectable (BRPC), and 19 (22%) locally advanced pancreatic cancer (LAPC). IOUS changed the resectability status in 32/85 (38%) patients (p < 0.001), including 8/19 (42%) patients with LAPC who were downstaged (4 to BRPC, 4 to RPC), and 22/32 (69%) patients with BRPC who were downstaged to RPC. Among patients with presumed superior mesenteric artery (SMA) involvement, 20/28 (71%) had no SMA involvement on IOUS. In 15 of these 20 patients a pancreatic resection was performed, all with R0 SMA margin.

Conclusion

IOUS during surgical exploration for pancreatic cancer and vascular involvement downstaged the resectability status in over one-third of patients, which could facilitate progress during surgical exploration. This finding should be confirmed by larger studies, including detailed pathology assessment.

Appreciative Inquiry: The Movement of Living
Authors: Pagès Jean
Published: February 2023

‘Appreciative Inquiry is not about being or thinking positively or negatively. Its call is to transcend this polarity. It is not about positive versus negative human experience, but the choice to inquire into what life is: the task of AI is the penetrating search for what gives life, what fuels developmental potential, and what has deep meaning – even in the midst of the tragic.’ David L. Cooperrider and Ronald Fry, 2020

From the hope of a result to the radiance of an attitude. A story that brings us back to the essence of Appreciative Inquiry – trusting in the process and keeping it alive, for it is at the edge of our field of vision that we can appreciate the movement of the living.

Case Article—Moneyball for Murderball: Using Analytics to Construct Lineups in Wheelchair Rugby
Authors: Chan Timothy C. Y. , Fernandes Craig , Loa Albert , Sandholtz Nathan
Published: February 2023

Motivated by the problem of lineup optimization in wheelchair rugby (WCR), this case study covers descriptive, predictive, and prescriptive analytics. The case is presented from the perspective of a new assistant coach of Canada’s national WCR team, who has been tasked by the head coach to use various analytics techniques to improve their lineups. Whereas the data and actors are fictitious, they are based on real data and discussions with the national team coach and sport scientists. To solve the case, students must conduct data analysis, regression modeling, and optimization modeling. These three steps are tightly linked, as the data analysis is needed to prepare the data for regression, and the regression outputs are used as parameters in the optimization. As such, students build proficiency in developing an end-to-end solution approach for a complex real-world problem. The primary learning objectives for the students are to understand the differences between descriptive, predictive, and prescriptive analytics, to build proficiency in implementing the models using appropriate software, and to identify how these techniques can be applied to solve problems in other sports or other application areas.

Stroke: aetiology, identification, management and the future
Authors: Sibson Lynda
Published: February 2023

Stroke is a significant clinical event and a medical emergency. More than 100 000 individuals in the UK experience a stroke annually, with one in four strokes occurring in people of working age. Stroke care costs the UK economy £25.6 billion a year. Evidence suggests that 90% of strokes are preventable, and there are some key modifiable risk factors. Stroke assessment and management are improving, with new pharmacological and surgical treatments, including mechanical thrombectomy. Recent advances in the use of technology and artificial intelligence for rapid radiological interpretation to aid decision making are fundamentally improving stroke management. A strategic stroke framework was launched in 2021, with the aim of improving care throughout the whole stroke pathway from prehospital management to rehabilitation and recovery. This paper outlines the aetiology of acute stroke in adults, related conditions, risk factors, assessment, treatments and financial implications, and discusses the new frameworks for stroke care as they apply to prehospital practice.

Assessing and managing wound pain
Authors: Brown Annemarie
Published: February 2023

Different wounds produce different types of pain. Pain assessment should form part of the initial wound assessment and be reassessed regularly. Verbal cues and pain assessment tools are useful when assessing pain, and observing non-verbal cues, such as grimacing, guarding the affected area and limited movement can also be helpful. Nurses should stay up to date on how to minimise pain during dressing changes, as this has been shown to cause some of the highest levels of pain. Several types of analgesia can be used to manage wound pain, and the type prescribed should be based on the type of wound pain and level of pain experienced by the patient. It is key that health professionals always acknowledge how pain impacts their patient's quality of life.

Reduction of Random Variables in EMC Uncertainty Simulation Model
Authors: Bai Jinjun , Wan Yixuan , Li Ming , Zhang Gang , He Xin
Published: February 2023

To improve the reliability of simulation results, uncertainty analysis methods were developed in the Electromagnetic Compatibility (EMC) field. Random variables are used to describe random events. The more random variables you have, the less efficient the simulation is. Therefore, many high-accuracy methods have the problem of dimensional disaster, which means the calculation efficiency decreases exponentially with the increase of the number of random variables. A random variable reduction strategy based on sensitivity analysis method is proposed in this paper, so as to improve the computational efficiency of the global uncertainty analysis method.
Decoupling Technique Based on Field Distribution on Ground Plane for WLAN MIMO Antenna Applications
Authors: Zhou Zicheng , Ma Xiao-Yu , Pang Zi-Yu , Huang Guan-Long , Chen Rui-Sen , Gu Changqing
Published: February 2023

An efficiently-decoupling method for multiple-input multiple-output (MIMO) antenna systems is proposed in this paper. A planar-modified monopole antenna operating at the WLAN band is chosen as the antenna unit. The antenna structure is based on the printed circuit board technique. By observing and analyzing the ground plane’s field distribution generated by high-order modes, it is found that several stable minimum current points can be excited along the edges of the ground plane. In doing so, a high isolation can be obtained if the other antenna is placed at one of these points. The measured results and simulated results have a good agreement with each other, which well validates the proposed design concept. In addition, compared with the traditional decoupling technology, this method can improve the isolation between antennas without adding additional structures, which has excellent practicality in wireless communication system applications.
On the Coupling Imbalance of the UWB BLC in the 5G Low Noise Amplifier Design
Authors: Abouelnaga Tamer G. , Abdallah Esmat A.
Published: February 2023

In this article, the design and the development of ultra-wideband UWB branch-line couplers BLCs with a novel method to control the coupling imbalance are proposed. The proposed UWB BLC is suitable for the 5G low-noise amplifier (LNA) design. UWB 4-branch BLC is designed using design curves developed using even and odd mode analyses to cover the 5G (3.3-5 GHz) frequency bands. The vertical branches of the UWB BLC are replaced by modified ones, and their effect on the coupling imbalance is investigated. The proposed BLC occupies an area of 33.9 × 15.7 mm2 Both conventional and modified BLC are fabricated, and their measured S-parameters are compared with analytical and simulated models. Based on the balanced amplifier topology, a 5G UWB low-noise amplifier is designed. The proposed BLCs and the MGF3022AM InGaP-HBT (Heterojunction Bipolar Transistor) are used to produce acceptable UWB performance. The balanced amplifier return loss, noise figure, and gain are investigated as BLCs coupling imbalance varies. The ultra-wideband LNA exhibits an acceptable small-signal gain, noise figure, input return loss, and output return loss across the 5G different frequency bands.
A Novel Compact Filtering Antenna for 5.0-GHz WLAN Communication System
Authors: Yan Shujia , Zhang Chongqi , Chen Qiang , Tong Mei Song
Published: February 2023

The proposed antenna presents a microstrip filter antenna with both filter out-of-band rejection characteristics and antenna radiation characteristics for WLAN communication system. The antenna consists of four U-shaped microstrip resonators, one Γ-shaped antenna, and one parallel coupling line. The Γ-shaped antenna has the filtering function as the last order resonator, and the parallel coupling line integrates the filter and antenna as the conductance converter. After simulation and test, the results show that the center frequency of the filter antenna is 5.25 GHz, the fractional bandwidthis 8.0% (5.0 − 5.42 GHz), the in-band gain changes smoothly, the maximum in-band gain is 3.059 dBi, the gain at 150 MHz outside the passband rapidly decreases to 10.0 dBi, and the overall out-of-band gain drops to below −24 dBi. The filter antenna has a simple structure and thin substrate, which optimizes the overall size of the filter and antenna, reduces the transmission loss between them, and is applicable to the RF front-end of wireless communication systems.

Authors: Deshmukh Ranjit V. , Kulkarni Aditi A.
Published: February 2023

Purpose: The aim of this study was to determine the role of Pirani scoring system for predicting the treatment of idiopathic clubfoot with the Ponseti technique. Materials and Methods: A retrospective study was conducted. The records of 132 idiopathic clubfeet of patients treated by the Ponseti method and scored by the Pirani system between May 2007 and September 2015 were analyzed. Result: Of the 132 feet, 101 (76.5%) feet of the patients required tenotomy. The mean number of casts required was significantly higher (P=0.033) for the group that required tenotomy (5.53 ± 1.6 casts) than the group that did not require tenotomy (4.87 ± 0.9 casts). Conclusion: The initial Pirani score is predictive of the number of casts that may be required and the need for a tenotomy of the Achilles tendon.

THR Using a 3D Printed Custom Made Acetabulum Component: A Case Report
Authors: P Avinash , Sangani Karthik , T Pavith Janardhan , KN Prajwal , Krishna Ajay , K Prajwal
Published: February 2023

Introduction: THR is one of the commonly performed adult arthroplasties in the world. Over the past 6 decades, Charnley low friction arthroplasty has evolved in design and concept. One among those recent advances is the use of 3D printing technology in arthroplasties. Purpose of this article is to discuss and share the details of a hip arthroplasty case where a customized 3D printed acetabulum component was used. Case: A 3 year postop case of acetabulum fracture fixation presented with arthritis of hip. CT revealed a periacetabular massive bone loss. After considering all options, decision was made to use a 3D printed acetabulum shell. Discussion: Complex THRs with special instrumentation and augmented implants are frequently seen in revision surgeries and post acetabulum fracture cases. Based on the size and pattern of the defect, IlioIschial cages, Triflange cups, Trabecular metal augments, CupCage constructs, Jumbo cups are some common options at a surgeons disposal while tackling an acetabulum bone loss challenge. A 3D manufactured component can be of aid when the defect is too large. It gives the advantage of being anatomically contoured. It also allows a porous structure for bone ingrowth. Conclusion: Life size models of the pelvis and the component gives an explicit simulation of the surgery, including the component placement and trajectory of the screws. This effective preoperative planning can improve the surgical precision and reduce the complications. Literature on the survival rates and long term complications of such 3d printed acetabulum shells is limited. Studies on the long term outcomes with usage of these implants would be insightful Keywords: 3D Printing, Complex THR, Customised acetabular shell
A Rare Case of Chondromyxoid Fibroma of Calcaneum: A Case Report
Authors: Mudramaiah Shekar , T Pavith Janardhan , Krishna Ajay
Published: February 2023

Chondromyxoid fibroma is a rare benign Primary tumour occurring in the calcaneum. We report a case of a 23-year-old woman with 3 months history of sudden onset right heel pain with no history of trauma. Which was exacerbated by movement such as walking and standing. A radiographic examination of the right foot and ankle revealed a lesion in the posterior part of the calcaneum. The calcaneum was further evaluated using an MRI scan which revealed a lytic lesion with clearly defined borders. The lesion was treated with curettage, iliac bone grafting, and cementing. Three months after surgery, the graft was consolidated with bone cement in place. There was no sign of recurrence at the one-year follow-up, and the patient had adequate ankle range of motion. Even though the tumour is rare, there is a need for physicians to recognize its radiological features and offer appropriate treatment options.

Family care for older persons in South Africa: heterogeneity of the carer’s experience
Authors: Moore Elena
Published: February 2023

The article highlights the heterogeneity of employed women’s experience of family care for older persons by focusing on multigenerational households. First, I argue that care for older persons must be understood in the context of multiple family responsibilities. Second, I show that care for older persons occurs in a context of inequalities that remain in post-colonial settings where there is highly uneven access to material resources, high levels of unemployment, poverty and limited social welfare provision. From this understanding of care, I argue that women’s position within wider care relations reveals elements of differentiation between women who occupy different class and racial positions.
Antimicrobial susceptibility test and antimicrobial resistance gene detection of extracellular enzyme bacteria isolated from tilapia (Oreochromis niloticus) for probiotic candidates
Authors: Mawardi Mira , Indrawati Agustin , Wibawan I. Wayan Teguh , Lusiastuti Angela Mariana
Published: February 2023

Background and Aim: Antimicrobial resistance (AMR) is a global problem that can increase mortality and morbidity rates and adversely affect health. Therefore, AMR control must be carried out in various sectors, including the fisheries sector, using probiotics. Bacteria can become resistant to antibiotics, including bacteria used for probiotics. This study aimed to isolate bacteria as potential producers of extracellular enzymes, phenotypic characterization, and antibiotic-resistant gene patterns.

Materials and Methods: In this study, 459 bacterial isolates were isolated from the stomach of tilapia in Indonesia. Tilapia was obtained from Sukabumi, Ciamis, Serang, Banjarnegara, Jayapura, Sorong, Manokwari Selatan, Takalar, Lampung, Batam, and Mandiangin. Enzymatic bacteria were identified. An antimicrobial susceptibility test was conducted by agar disk diffusion, and genotypic detection of encoding genes was performed using a molecular method.

Results: This study obtained 137 isolates (29.84%) that can produce extracellular enzymes. The highest number of E-sensitive isolates was found, including 130 isolates (94.89%). Six isolates (6/137) can produce four enzymes (amylase, protease, cellulose, and lipase), and they were sensitive to antibiotics. A total of 99 isolates can produce extracellular enzymes, and they were sensitive to antibiotics. Such isolates serve as a consortium of probiotic candidates. The isolates that are resistant to oxytetracycline (OT), erythromycin (E), tetracycline (TE), and enrofloxacin (ENR) included 15 isolates (10.95%), seven isolates (5.11%), three isolates (2.19%), and one isolate (0.73%), respectively. In addition, four isolates (2.92%) were detected as multidrug-resistant. The tet(A) gene obtained the highest result of detection of resistance genes in isolates that were intermediate and resistant to TE and OT. Isolates that serve as ENR intermediates have a high qnr(S) resistance gene.

Conclusion: The data in this study provide the latest update that bacteria can serve as a consortium of potential probiotics with antibiotic-resistant genes for the treatment of fish. Bacteria that are intermediate to antibiotics may contain resistance genes. The results of this study will improve the policy of probiotic standards in Indonesia.

Published: February 2023

The diversity of popular names used in fish nomenclature off the Brazilian coast makes it difficult to identify species, and many names have their origins in Indigenous languages, mainly Tupi-Guarani. This study sought to understand and update the list of the most popular names and assess some ethnotaxonomic patterns employed by artisanal fishers from the Brazilian Amazon Coast in naming elasmobranchs. Interviews with 314 fishermen from 17 coastal municipalities were carried out employing a semi-structured form, banners, and photographic records of local elasmobranch species, addressing characteristics applied to species identification. A total of 130 ethnospecies were identified (113 names in Portuguese and 17 of Tupi-Guarani origin) for the identification of 22 and 18 species of sharks and rays, respectively. The highest degree of homonyms occurs interspecifically for the Dasyatidae, Mobulidae, Pristidae, Urotrygonidae, Carcharhinidae, Sphyrnidae and Triakidae families. Sphyrna tiburo and Hypanus guttatus comprised the taxa with the highest diversity of common names. Morphological characteristics such as shape, colors, texture, and size of certain body parts are the ethnotaxonomic patterns most applied in shark and ray identification. We conclude that the use of common names for elasmofauna facilitates communication between fishers and that the scientific approach to this local ecological knowledge is fundamental for the management and sustainability of fisheries in the long term.
Open Theism and Perfect Rationality
Authors: Mullins Ryan T.
Published: February 2023

Dean Zimmerman has made significant contributions to metaphysics, philosophy of time, and philosophy of religion. In this paper, I set my focus on Zimmerman’s approach to God, time, and creation. Zimmerman has defended a model of God called open theism on which God is essentially temporal. In this paper, I will first articulate open theism. Then I will explore a series of puzzles related to God’s perfect rationality and creation. These can be stated as the following three questions. Why didn’t God create sooner? Why did God create anything at all? Why did God create this universe in particular?
Mixed Constitutions in East Asia: South Korea and Taiwan as Examples
Authors: Lee Yi-Li , Chang Wen-Chen
Published: February 2023

The study of illiberal constitutions has recently generated enormous scholarly interests. Few, however, have focused on whether democracies may still embrace constitutionalism mixed with illiberal elements. This article explores mixed constitutions of South Korea and Taiwan, the two democracies with vibrant civil societies in East Asia. Three distinctive features in both constitutions have demonstrated illiberal elements, including duty clauses imposed upon citizens, directives requiring the State to enact laws to fulfill the goals of governance, and constitutional cultures that exhibit high deference to political elites based on the Confucian tradition. This article further examines the impacts of such mixed constitutions on three challenging issues: managing pandemic crisis, applying artificial intelligence, and combating fake news. This article finds mixed features of illiberal and democratic constitutions in the two countries by giving their governments more space in managing urgent crises, showing higher deference to experts who are generally trusted by the public, and making compromises to individual rights for greater public good. However, this does not imply that the government is not made democratically accountable, or rights and freedoms are not asserted or valued by individuals. To the contrary, nongovernmental organizations and courts in the two countries continue to act as a counterbalancing force, challenging the government’s policies and decisions if not reasonably balanced, weakening the tendency of power concentration that has been seen in other countries where democratic backsliding or authoritarian governance is gradually revived.
What are We Talking About When We Talk About “Mixed Constitutions”? Towards a Typology of Constitutional Mixture
Authors: Roznai Yaniv
Published: February 2023

This article argues that constitutional mixture should be regarded as an inherent, inevitable feature of constitutions, and to some degree all constitutions are mixed. Thus, “mixed constitutions” should not be regarded as a distinct category of constitutions. Instead of asking whether a constitution is mixed, it might therefore be more useful to ask in which characteristics and to what extent a constitution is mixed. To demonstrate this, the article provides a preliminary typology of constitutional mixture considering the form or system of government; the nature or character of government; the religious or secular identity; the flexibility or rigidity of the constitution; and its model of judicial enforcement—judicial or parliamentary supremacy. Examining these constitutional features, allows to shed light on the three different dimensions of “constitutional mixture”: First, the various features of the constitutional order do not function in a binary yes-or-no manner but appear and move along a spectrum. Second, the various features of the constitution change with time. Third, the various features of the constitutional text may be in tension with the features of the society.
Permissive and Unpermissive Constitution Making
Authors: Lerner Hanna
Published: February 2023

The article explores the long-term consequences of permissive constitutional arrangements, drawing on a comparative study of Israel, India and Sri Lanka. In all three countries, constitutional drafters at the foundational stage adopted permissive arrangements that avoided controversial decisions on conflicted identity-related issues. In all three cases, three to six decades after independence, the permissive constitutional approach was replaced by more decisive formal constitutional principles. Such unpermissive constitution making was meant to limit the range of options available for future legislation or constitutional interpretation by courts, and preferred nationalist, religious and ethnocentric identity. This article seeks to investigate why such developments occurred in the three countries, and what can be learned from them about the durability and normative advantages of permissive constitutional arrangements. Empirical analysis of the long-term consequences of permissive arrangements illustrates the limited durability that appeared to characterize some of these arrangements. The present assessment also reveals how in some cases, the main ideational conflict at the heart of the constitutional debates has shifted over the years. Nevertheless, the central argument put forth by this article is that, despite ongoing challenges, permissive constitutional arrangements should still be regarded as a valuable constitutional tool for advancing political compromise and facilitating stable democratic institutions. The analysis demonstrates the crucial role permissive constitutions may have as a political tool designed to circumvent violent conflicts and as an analytical tool, thereby offering insight into current constitutional conflicts over ideational issues.

space group. The central copper(II) ion displayed a distorted square–pyramidal geometry and was connected by one chlorido co-ligand (Clˉ), one 3,5,6-tcpa anionic chelator and one chelating 2,2’-bipy ligand to afford a mononuclear structure. 1 is further extended into a 3D network by the non-covalent interactions of H⋯Cl, H⋯O hydrogen bonds, aromatic π⋯π stacking together with Cl⋯Cl halogen bond interactions. The co-crystallization process, the crystal structure of 1 as well as the Hirshfeld surface analysis for 1 have been analyzed and described. In addition, the flexible conformation of phenoxy methylene group among 1, triclopyr acid and its previously reported co-crystallized compound also have been carefully compared and discussed.
Subversivos modernos: Althusius, Spinoza e Rousseau
Authors: RODRIGUES T C M
Published: February 2023

Modern political theory is commonly referenced by the clash between absolutism and liberalism to have emerged between the seventeenth and eighteenth centuries. There are, however, thinkers who built elements beyond the modern State and who inform the current democratic debate. As such thinkers are historically modern, but theoretically contemporary, they are modern subversives. This article provides a comparative analysis of the political ideas of three theorists who may be considered as modern subversives: the German Johannes Althusias, the Dutchman Baruch Espinosa, and the Genevan to have settled in France, Jean Jacques Rousseau. These thinkers discussed the themes of popular sovereignty, the democratic power of the multitude, and on the general will as overcoming representation. What unites them is the radical and subversive desire to establish, against any form of oppression, the demos as sovereign. Reconsidered in the twentieth and twenty-first centuries, these authors have not only informed the contemporary debate on democracy, but also contributed to the very renewal of political theory.

Published: February 2023

The events, related to the special military operation, not only actualize Ukrainian issues, but also force us to turn to the experience of another Slavic country, former republic of the USSR – Belarus. In the Republic of Belarus in early 90s, the same processes were unfolding, as in Ukraine. However, 30 years later, the political and economic results of the post-Soviet transformation turned out to be different. What is the reason for the difference? This paper is one of the first attempts to answer why Belarus is not Ukraine?
Elections in Bosnia and Herzegovina - 2022
Authors:   Institute of Europe, Russian Academy of Sciences, Eremin Denis
Published: February 2023

On 2 October 2022, Bosnia and Herzegovina (BiH) held general elections at all levels, including collective Presidency. Elections in Bosnia have regional significance, because the country is still an area of a frozen conflict. The elections’ results indicate that the ethnic and confessional affiliation remains to be a deciding factor in electoral processes. The collective West has already tried (unsuccessfully) to centralize the state using the Office of High Representative (OHR) with the goal of future integration of BiH into the euroatlantic structures. After the failed attempt, it has changed its approach to the Bosnian problem. Several indicators of this process were found: concessions of OHR to the Croatian community, as well as the presidential campaign in Republika Srpska, accompanied by a surge of protest activity.
European Union trade in 2022: external balance deficit and growth of internal interactions
Authors:   Institute of Europe, Russian Academy of Sciences, Kotov Alexander
Published: February 2023

EU foreign trade in 2022 has been developing under relentless inflation, the burden of energy prices and food products. In 10 months of 2022, the growing import dependence of the EU on the USA and China was registered. Russia is holding its ground due to a sharp rise of its exports’ value. Because of agricultural imports, foreign trade cooperation of the EU with Ukraine strengthens. The economies of the EU member states are still to overcome the consequences of the pandemic. At the same time, the EU trade deficit has significantly increased since the end of 2021. In the medium term, the European Single market will remain under the mounting pressure from more profitable economic locations.

Published: February 2023

Introduction: Acute type A aortic dissection (ATAAD) is a catastrophic disease with fatal outcomes. Malperfusion syndrome (MPS) is a serious complication of ATAAD, with an incidence of 20–40%. Many studies have shown that MPS is the main risk factor for poor ATAAD prognosis. However, a risk scoring system for ATAAD based on MPS is lacking. Here, we designed a risk scoring system for ATAAD to assess mortality through quantitative assessment of relevant organ malperfusion and subsequently develop rational treatment strategies.

Methods and analysis: This was a prospective observational study. Patients’ perioperative clinical data were collected to establish a database of ATAAD (N≥3000) and determine whether these patients had malperfusion complications. The Anzhen risk scoring system was established on the basis of organ malperfusion by using a random forest survival model and a logistics model. The better method was then chosen to establish a revised risk scoring system.

Ethics and dissemination: This study received ethical approval from the Ethics Committees of Beijing Anzhen Hospital, Capital Medical University (KS2019034-1). Patient consent was waived because biological samples were not collected, and no patient rights were violated. Findings will be disseminated at scientific conferences and in peer-reviewed publications.

Background: Spontaneous heparin-induced thrombocytopenia is a pro-thrombotic syndrome in which anti-heparin antibodies develop without heparin exposure.

Case presentation: A 78-year-old man who underwent a successful lumbar laminectomy presented to the hospital 5 days after discharge for stroke-like symptoms and was found to have acute infarcts of the bilateral frontal lobes. The patient was found to be severely thrombocytopenic and was incidentally found to have an inferior wall myocardial infarction. Further investigation led to the diagnosis of bilateral lower extremity deep vein thromboses. His overall clinical presentation prompted a detailed hematologic workup that indicated positivity for heparin-induced thrombocytopenia despite no previous exposure to heparin products.

Conclusions: This case illustrates a patient with no prior lifetime heparin exposure who underwent laminectomy with subsequent development of acute infarcts of the bilateral frontal lobes, an inferior wall myocardial infarction, and bilateral lower extremity deep vein thromboses, with concern for sequelae of spontaneous heparin-induced thrombocytopenia.
