Acute Aortic Injury and Bilateral Pulmonary Emboli in the Setting of COVID-19.

In this report, we present the case of a 72-year-old female diagnosed with an aortic dissection variant and bilateral pulmonary emboli (PE) in the setting of Coronavirus Disease of 2019 (COVID-19) infection. The patient was transported from home to the emergency department (ED) via emergency medical services (EMS) with acute chest pain and dyspnea. After arriving at the ED, she was hypoxic on her baseline supplemental O2 requirement and tachycardic and tachypneic. Computed tomography (CT) angiogram of the chest showed evidence of possible thoracic aortic dissection and bilateral PE. The patient was ultimately transported to a tertiary center for operative aortic repair and bilateral embolectomy and, fortunately, survived the procedures. Interestingly, during operative repair of the aorta, no obvious dissection flap was noted, but rather evidence of a limited tear in the intimal layer of the aorta. This is an interesting case as acute aortic injuries in the setting of COVID-19 infection have not been as widely documented as PE in the setting of COVID and highlight the need for further research on the possible association between them.

Aortic wrapping is life-saving in high-risk acute aortic dissection and intramural haematoma.

Aortic wrapping is a controversial repair in patients presenting with acute type A aortic dissection or intramural haematoma, but this method may be a potential alternative to medical treatment or conventional repair in patients aged >80 years and in those presenting with prohibitive co-morbidities such as stroke, circulatory collapse, full oral anticoagulation with the last generation drugs. We report on 5 high-risk and/or patients over 80 years who received external aortic wrapping with or without cardiopulmonary bypass during the last 18 months. All survived the procedure and could be extubated early postoperatively. No patient remained on the intensive care longer than 2 days and all were discharged without additional complications. Postoperative radiological control was acceptable and no patient had any new aortic event up to 18 months postoperatively.

Surgical treatment of left atrial dissection caused by percutaneous coronary intervention.

Left atrial dissection (LatD), also known as left atrial intramural haematoma, is a rare condition that requires rapid diagnosis and frequently calls for timely surgical intervention. Diagnosis can be challenging because of a lack of definitive clinical criteria, and a patient's situation can be complicated by co-morbidities, including unstable haemodynamics. We surgically repaired a case of LatD related to percutaneous coronary intervention (PCI). The operation went smoothly, and the patient was discharged one week after the operation. For LatD patients with co-morbidities, especially haemodynamic disorders, active surgical intervention is recommended.

Advances in Management of the Stroke Etiology One-Percenters.

PURPOSE OF REVIEW: Uncommon causes of stroke merit specific attention; when clinicians have less common etiologies of stoke in mind, the diagnosis may come more easily. This is key, as optimal management will in many cases differs significantly from "standard" care. RECENT FINDINGS: Randomized controlled trials (RCT) on the best medical therapy in the treatment of cervical artery dissection (CeAD) have demonstrated low rates of ischemia with both antiplatelet and vitamin K antagonism. RCT evidence supports the use of anticoagulation with vitamin K antagonism in "high-risk" patients with antiphospholipid antibody syndrome (APLAS), and there is new evidence supporting the utilization of direct oral anticoagulation in malignancy-associated thrombosis. Migraine with aura has been more conclusively linked not only with increased risk of ischemic and hemorrhagic stroke, but also with cardiovascular mortality. Recent literature has surprisingly not provided support the utilization of L-arginine in the treatment of patients with mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS); however, there is evidence at this time that support use of enzyme replacement in patients with Fabry disease. Additional triggers for reversible cerebral vasoconstriction syndrome (RCVS) have been identified, such as capsaicin. Imaging of cerebral blood vessel walls utilizing contrast-enhanced MRA is an emerging modality that may ultimately prove to be very useful in the evaluation of patients with uncommon causes of stroke. A plethora of associations between cerebrovascular disease and COVID-19 have been described. Where pertinent, authors provide additional tips and guidance. Less commonly encountered conditions with updates in diagnosis, and management along with clinical tips are reviewed.

Creation of 21st century anatomy facilities: designing facilities for integrated preclinical education in the Middle East.

BACKGROUND: The establishment of new anatomy facilities needs to accommodate a combination of modern teaching modalities that best align with evidence-based best teaching practices. This article describes the process in which our state-of-the-art anatomy laboratories were designed and implemented, and how these facilities support aspects of modern anatomy education. METHODS: A list of best practices for anatomy education in a modern medical curriculum was summarized from the literature. To assess student satisfaction, a survey related to student perception of the anatomy facilities (5-point Likert scale) was conducted. RESULTS: Our educational modalities include a broad range of teaching approaches. The Instructional Studio houses prosected and plastinated specimens, and cadaveric dissections are performed. Each of our three Dry Laboratories allow for active learning and interaction between small student groups. The Webinar Room acts as a conference room for departmental and online meetings, discussions with students, and dialogues with affiliated hospitals via the internet. The Imaging Center is equipped with a Sectra® medical educational platform, CAE Vimedix® Virtual Medical Imaging Ultrasound Training System, and Philipps Lumify® Ultrasound devices to train students to conduct and interpret sonographic images. Moreover, the Complete Anatomy® program is made available to all our students. CONCLUSION: The layout of our newly created Anatomy Facilities allows for all aspects of modern medical education mentioned in the literature. These educational modalities and teaching approaches are highly appreciated by our faculty and students. Moreover, these technologies allowed for a smooth transition from on-site anatomy teaching to online education during the COVID pandemic.

Are Biopsies Sufficient for Diagnosis Comparison of ESD and Forceps Biopsy Findings for Colon and Rectal Lesions

Introduction: Endoscopic submucosal dissection (ESD) is a minimally invasive technique used for removal of superficial dysplastic or early cancerous colon and rectal lesions. For larger lesions ( .20mm) that are not amenable to endoscopic mucosal resection, superficial biopsies are typically taken prior to referral for ESD. The aim of this study was to evaluate the degree of concordance between superficial forceps biopsies and ESD pathology. Method(s): A retrospective medical record review was performed including consecutive patients who underwent ESD of colon and rectal lesions at a tertiary care center between 10/2018 and 11/2021. Pathology results from outside hospital and same institution pre-ESD superficial forceps biopsies were compared to ESD pathology results. The primary outcome was the number of patients found to have higher disease severity on ESD pathology compared with superficial forceps biopsies. Result(s): Of the 84 patients who underwent ESD of colon or rectal lesions, 72 had pre-ESD superficial forceps biopsies which were taken at an outside hospital (n=48) or at the same institution (n=36). The average length of time between outside hospital superficial forceps biopsies and ESD was 91 days compared to 75 days for those performed at the same institution. Delays between superficial forceps biopsies and ESD may be related to the COVID-19 pandemic prolonging time between procedures. Pathology findings after ESD differed from superficial forceps biopsies in 31/72 patients (43%) with 21 patients receiving upgraded disease severity and 6 patients receiving a new cancer diagnosis based on ESD pathology. Patients who received a new cancer diagnosis had more days between superficial forceps biopsies and ESD compared with the whole cohort (86 vs 75, respectively). Conclusion(s): While superficial forceps biopsies of colon and rectal lesions were typically concordant with ESD pathology, 29% of patients in this cohort received upgraded disease severity based on ESD pathology. This shows that while superficial forceps biopsies can aid in diagnosis, en bloc resection via ESD remains critical for accurate diagnosis of large colon and rectal lesions. These results also show that ESD is not only diagnostic but therapeutic given 75% of the patients in this cohort achieved R0 resection.

Coronary artery bypass grafting after iatrogenic coronary artery dissection: A single center eight years' experience

Background: Iatrogenic coronary artery dissection during diagnostic or therapeutic catheterization is a rare and mortal complication that may result in a newly developed myocardial infarction. In this study, we aimed to share the results of CABG treatment of patients with iatrogenic coronary artery dissection after coronary angiography (CAG) in our clinic. Method(s): All patients who underwent CAG or percutaneous coronary intervention (PCI) in our hospital between January 2014 and December 2021 were analyzed retrospectively and patients who underwent CABG after iatrogenic coronary artery dissection were included in the study. The dissection classification was achived according to the National Heart, Lung and Blood Institute (NHLBI) classification. Result(s): During the eight years, CAG was applied to 20,398 patients and PCI to 9583 patients. Needed to treat CABG in iatrogenic coronary artery dissection developed in 17 of the patients (0.06%). LMCA was dissected in 6 (35.3%) patients and LAD in 6 (35.3%), CX in 2 (11.8%) and RCA dissection in 3 (17.6%). 3 patients (17.6%) had an intubation time longer than 48 hours. One of them has recently had a COVID infection. Another was suffering from pulmonary edema. The other patient died on the 4th postoperative day due to low cardiac output. The length of stay in the intensive care unit was 2 (min: 1 - max: 13) days. The hospital stay was 6 (min: 4 - max: 20) days. Conclusion(s): The development of a critical clinical condition prior to surgery is strongly associated with a higher probability of early and late postoperative death. For this reason, it is clear that the treatments applied at every stage of the pre-, per-, and postoperative period are the most important determinants of the results.Copyright © 2023, CKS.

Covid-19 Vaccine Associated Acute Myocarditis

Case Presentation: A 19 year old male presented with sudden onset chest pain radiating to back. He was a smoker and denied using cocaine since his last hospitalization for cocaine-induced myocardial infarction 2 years ago. UDS was negative. EKG showed normal sinus rhythm with no ST-T wave changes. Initial troponin was 0.850. Potassium levels were low at 2.9 mmol/L but other labs were normal. Chest CT angiography ruled out aortic dissection. He was started on heparin drip. Stat Echocardiogram showed LVEF of 55-60% with no wall motion abnormalities. Repeat potassium levels normalized after replacement, however, his troponins were trending up from 3.9 and 11.5. He continued to complain of severe chest pain, so underwent cardiac catheterization which showed normal coronary arteries and LVEF 55-60%. Heparin drip was discontinued and NSAIDs and colchicine were started. Cardiac MRI (see Figure) was done that showed patchy mid-wall and epicardial delayed gadolinium enhancement involving the basal inferolateral wall, with mild hyperintense signal on the triple IR sequence, suggestive of myocarditis. On further probing, he reported receiving a second dose of Moderna COVID vaccine 3 days prior to presentation. Discussion(s): In December 2019, a novel RNA virus causing COVID-19 infection was reported, which quickly reached a pandemic level. COVID-19 vaccines were granted emergency use authorization by FDA. With millions of people receiving COVID-19 vaccinations worldwide, rare adverse effects are now being reported. The benefits of vaccination undoubtedly outweigh any minor side effects. However major adverse effects like this are potentially fatal. This case report warrants further investigation into the association of myocarditis with COVID-19 vaccinations and further recommendations regarding vaccination in younger adults.

The Coronavirus Double Threat: A Rare Presentation of Chest Pain in a Young Female.

Severe acute respiratory syndrome coronavirus 2 (SARS-COV 2) led to global coronavirus disease 2019 (COVID-19) pandemic. The virus affects the respiratory system predominantly and has resulted in multiorgan complications. Myocarditis, acute coronary syndrome (ACS), cardiogenic shock, and sudden cardiac death were common cardiac manifestations of COVID-19. Spontaneous coronary artery dissection (SCAD) is a rare form of coronary artery disease that is previously reported in patients with COVID-19. SCAD usually occurs in a middle-aged woman with few or without any cardiovascular risk factors. The gold standard for its diagnosis is coronary angiography. The SCAD treatment recommendations depend on the hemodynamic status: conservative therapy in hemodynamically stable SCAD patients and urgent revascularization in hemodynamically unstable SCAD patients. The exact pathophysiology of COVID-19 associated with SCAD is unknown. It is considered a combination of systemic inflammatory response and localized vascular inflammation. The case reported is of COVID-19-associated SCAD in a patient with no history of cardiovascular disease later complicated by the transient ischemic attack (TIA) and left ventricular (LV) thrombus.

Impact of the time elapsed between prostate biopsy and surgery on the accuracy of nomograms predicting lymph node invasion in patients with clinically localized prostate cancer.

We aimed to investigate whether the performance characteristics of available nomograms predicting lymph node invasion (LNI) in prostate cancer patients undergoing radical prostatectomy (RP) change according to the time elapsed between diagnosis and surgery. We identified 816 patients who underwent RP with extended pelvic lymph node dissection (ePLND) after combined prostate biopsy at 6 referral centers. We plotted the accuracy (ROC-derived area under the curve [AUC]) of each Briganti nomogram according to the time elapsed between biopsy ad RP. We then tested whether discrimination of the nomograms improved after accounting for the time elapsed between biopsy ad RP. The median time between biopsy and RP was 3 months. The LNI rate was 13%. The discrimination of each nomogram decreased with increasing time elapsed between biopsy and surgery, where the AUC of the 2019 Briganti nomogram was 88% vs. 70% for men undergoing surgery <2 vs. >6 months from the biopsy. The addition of the time elapsed between biopsy ad RP improved the accuracy of all available nomograms (P < 0.003), with the Briganti 2019 nomogram showing the highest discrimination. Clinicians should be aware that the discrimination of available nomograms decreases according to the time elapsed between diagnosis and surgery. The indication of ePLND should be carefully evaluated in men below the LNI cut-off who had a diagnosis more than 6 months before RP. This has important implications when considering the longer waiting lists related to the impact of COVID-19 on healthcare systems.

The use of monopolar diathermy in laparoscopic appendectomy, Is it really safe?

Background: There have been numerous techniques used in laparoscopic appendectomy (LA) to divide the mesoappendix, including LigaSure, Harmonic scalpel, clips, endoloop ligatures, Endo GIA staplers, and bipolar coagulation. However, few studies have investigated monopolar diathermy for mesoappendix division. Therefore, this study aimed to assess both its safety and efficacy in LA. Method(s): In this prospective non-randomized study, patients (n = 87) who underwent LA for acute appendicitis were included. The bipolar electrocautery was used for mesoappendix division in the first 33 patients (BC group), while the monopolar electrocautery was used in the next 54 patients (MC group). Result(s): The median operative time was significantly shorter in the MC group (42 min. vs 47 min. in BE group, p = 0.01). One patient converted to open surgery in the MC group due to uncontrollable bleeding. There were no significant differences between both groups regarding postoperative complications and hospital stay (p = 0.91, p = 0.13, respectively). Conclusion(s): Monopolar electrocautery is safe and effective for mesoappendix division in LP in comparison to bipolar electrocautery. However, larger and multicentric studies are required to validate our results.Copyright © 2023 The Authors

Optical Coherence Tomography Guided Percutaneous Coronary Intervention of Spontaneous Recanalized Coronary Thrombus

Clinical Information Patient Initials or Identifier Number: 56 years old woman Relevant Clinical History and Physical Exam: A 56-years-old woman with underlying history of hyperlipidemia without medical treatment. She experienced effort precordial tightness and shortness of breath for 8 months after COVID-19 vaccination. She received exercise TI 201 myocardial perfusion scan showed myocardial ischemia. EKG found old anterior wall myocardial infarction. Echocardiogram showed left ventricle anterior wall hypokinesia, LVEF 38%. [Formula presented] Relevant Test Results Prior to Catheterization: Coronary angiogram found left anterior descending artery from proximal to middle 70~80% long diffuse stenosis with spontaneous recanalized coronary thrombus. Also left anterior descending artery diagonal 2 branch bifurcation was 70% stenosis with spontaneous recanalized coronary thrombus (Medina 1.1.1) [Formula presented] [Formula presented] Relevant Catheterization Findings: Coronary angiogram found left coronary artery middle and diagonal branch braided apperance. OCT found recanalized thrombi, high backscattered septa that divided the lumen into multiple small cavities, created "lotus root" appearance. [Formula presented] [Formula presented] Interventional Management Procedural Step: Left main coronary artery was engaged with EBU3.5/7F guiding catheter. We advanced Runthrough to LAD-D and second wire Sion to LAD-DB2 but can't advance. Then we used with Sasuke double lumen catheter and successful advance Pilot 50 to LAD-DB2 distal. OCT found multiple channels with LAD-D and DB2 branch wires are at different channels, so we used cutting balloon 2.5 x 10mm as unconventional method. OCT was rechecked again and successfully destroyed to multiple channel of SRCT between LAD and Diagonal 2 branch. Long diffuse dissection found after POBA so we deployed to LAD-DB2 branch with DES Synergy 2.5 x 16mm and advanced LAD-M bifurcation to Pantera LEO 3.0 x 20mm and done Mini-Crush technique. Deployed for main vessel LAD-P to M long diffuse lesion with DES Xience 2.75 x 48mm at 14atm. Then we rewire Fielder XTR to DB2 branch with the support of Sasuke but difficult to deliver to Diagonal 2 branch. POT with Pantera LEO 3.0 x 20mm to LAD stent proximal site. Then successfully advance Fielder XTR to DB2 branch. Final kissing balloon technique with Pantera 2.75 x 12mm to LAD main vessel and MINI TREK 1.5 x15mm to LAD-DB2. [Formula presented] [Formula presented] [Formula presented] Conclusion(s): This is a case of SRCT (Spontaneous Recannalized Coronary Thrombus) that was confirmed with OCT. For secure side branch patency, main trunk & side branch wire must be in same channel. Due to relatively unstable hemodynamic, we chose to use unconventional method with 2.5 x 10mm Wolverine cutting balloon. Relatively large side-branch diagonal branch, possible dissection at ostial diagonal branch, we chose upfront 2 stents, bifurcation stenting technique we used Mini-crush stenting. Some difficult when rewire to side branch and initial POT to main branch stent proximal and then successfully delivered. If without guidewire recross, unrescuable side-branch occlusion can be occurred.Copyright © 2023

Breast Cancer-Related Lymphedema and its Relationship to Major Landmark Trials in Surgical Oncology and Radiation Oncology

INTRODUCTION: Many landmark trials have challenged the need for extensive axillary surgery and radiation in breast cancer patients. De-escalation of axillary treatment could potentially result in less breast cancer-related lymphedema (BCRL). Our study aims to define the incidence and trends of BRCL over the last 15 years. METHOD(S): Since 2005, our institution has prospectively screened breast cancer patients for lymphedema during and after treatment with a Perometer. 2,334 women diagnosed with breast cancer with baseline arm volume measurements and at least 2 follow-up measurements were divided into 3 cohorts based on date of surgery (Cohort 1: 2005-2010, Cohort 2:2011-2016, Cohort 3: 2016-2022). The cohorts were selected to coincide with publications of the landmark trials NSABP B-32, ASCOG Z0011, ASCOG Z1071, and EORTC 10981-22023 AMAROS which demonstrated safety in reducing the number of axillary lymph node dissections (ALND). Lymphedema was defined as a relative volume change of 10% or greater from preoperative baseline at least 3 months post-operatively. In cases of bilateral surgery, the weight-adjusted arm volume change equation was utilized. Cohort, age, BMI, axillary surgery type, chemotherapy timing, radiation type, and surgery type were all included in the multivariate analysis. RESULT(S): The overall incidence of BCRL was 12.8%, with a 29.6% incidence for those undergoing ALND and a 6.4% incidence for those undergoing sentinel lymph node biopsy. While the number of ALND performed decreased between cohorts (Figure 1), there was no significant difference in BCRL between assigned cohorts (HR 1.02 (95% CI [0.69, 1.51], p=0.930 for cohort 3 vs cohort 1). On multivariate analysis, significant associations with development of BCRL were identified with older age (HR 1.02;95% CI [1.01, 1.03], p=0.002), higher BMI (HR 1.05;95% CI [1.04, 1.07], p< 0.0001) and ALND (HR increased the risk of (HR 3.67;95% CI [2.62, 5.13], p< .0001). Regional lymph node radiation was not significantly associated with BCRL. CONCLUSION(S): Despite a reduction in the number of ALND performed over time, we did not see a dramatic reduction in the incidence of BCRL. Interestingly, between cohort 2 and cohort 3 there was a stable incidence of ALND which could be related to the COVID pandemic with an increase in more advanced cancers and a decrease in the ability to screen patients for BCRL during that time period.

Occlusive Explosion

Clinical Information Patient Initials or Identifier Number: A Relevant Clinical History and Physical Exam: 47yr old man, suffered a blast injury at the workplace after an O2 tank exploded while he was transferring liquid gas into a tank for welding purposes. The impact has caused him to temporary loss of consciousness. Upon awakening, he had severe chest pain associated with shortness of breath. On examination, superficial partial thickness injury on the chest wall, and lungs: reduced breath sound bi-basally, no murmur heard. BP:106/77mmHg, HR:100/min, SPO2 100% on HFM 15L/min. [Formula presented] [Formula presented] [Formula presented] Relevant Test Results Prior to Catheterization: Serial ECGs were done and showed dynamic changes in the anterior leads Bedside echo before invasive coronary angiograms shows mild LVSD, normal valves, and no pericardial effusion [Formula presented] [Formula presented] Relevant Catheterization Findings: Right radial approach 6F system Opitorque catheter for diagnostic angiogram LMS: smooth LAD: ATO mid LAD, DG1 prox ATO LCx: smooth RCA: smooth Impression: ATO to LAD and Diagonal 1 ( Dual ATO) [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: Right radial coronary angiogram via 6F system EBU 3.0 engaged with good support Sion blue wired into LAD, export catheter delivered, and aspirated red thrombus Pre-dilated with Sapphire 3 SC 2.5x15mm @ 6-10ATM Flow established in LAD, however, decided to interrogate DG1 as it shows ATO BMW wired into the DG1 and pre-dilated with Sapphire 3 SC 2.0x15mm Noted nonflow limiting dissection and decided to stent DG1 with 2.25x34mm@12ATM, dissection sealed and TIMI III flow established Stented mid LAD with 2.5x30mm @12ATM just before LAD/DG1 bifurcation, then stented proximal LAD with 2.5x 26mm@ 12ATM. Post-dilated LAD with 2.75x15mm@ 14-20ATM TIMI II-III flow IV Tirofiban has been given a loading dose due to a high thrombus burden and sluggish flow [Formula presented] [Formula presented] [Formula presented] Conclusion(s): Myocardial infarction is a rare complication of blunt chest trauma. This case demonstrates how blast shock waves result in the dissection of the coronary vessel leading to total occlusion of the two vessels. It also promotes red thrombus within the coronary vessels. Percutaneous coronary intervention is the most suitable way to treat this condition. Intravascular imaging such as IVUS or OCT would be beneficial to demonstrate the physiology behind this MI and would also be helpful in planning and optimizing the lesions. Unfortunately, intravascular imaging was not used for this patient to reduce procedural time as he was treated during the height of the COVID pandemic.Copyright © 2023

Superior Cerebellar Artery Dissection in a Patient Diagnosed with Reversible Cerebral Vasoconstriction Syndrome: A Case Report

Arterial dissection is an uncommon complication of reversible cerebral vasocon-striction syndrome (RCVS). We describe the case of a 35-year-old woman with a migraine history who presented with recurrent thunderclap headache and focal neurological signs, including right hemiataxia. She had been diagnosed with COVID-19 disease two weeks earlier. Neuroimaging revealed multifocal stenosis of the posterior circulation arteries and dissection of the right superior cerebellar artery. She improved significantly throughout her one-week hospitalization and maintained only mild ataxia. The interplay between COVID-19 disease, RCVS, and arterial dissection requires further investigation.Copyright © Author(s) (or their employer(s)) and Sinapse 2022.

COVID-19 and Spontaneous Coronary Artery Dissection: Association or Causality

Clinical Information Patient Initials or Identifier Number: JS Relevant Clinical History and Physical Exam: A 55-year old woman was brought to emergency department complaining of sudden onset squeezing chest pain radiating to her arm and jaw and associated with giddiness. She had flu like illness a day prior to her presentation associated with malaise, arthralgia and dry cough. She had history of hypertension. Physical examination revealed dual heart sounds and clear lung fields to auscultation. Relevant Test Results Prior to Catheterization: Electrocardiogram (ECG) showed normal sinus rhythm and the cardiac enzymes were elevated;high sensitivity troponin-I, 23000 ng/L (range0-10 ng/L). RNA PCR was positive for SARS-CoV-2 (COVID-19). D-Dimer was 303microgram/L (normal <500). Transthoracic echocardiogram showed severe hypokinesis of the mid inferolateral wall with left ventricular ejection fraction (LVEF) 52%. Chest X-ray showed no focal consolidation. [Formula presented] [Formula presented] Relevant Catheterization Findings: Invasive coronary angiogram showed tortuous coronary arteries with abrupt narrowing of mid- distal Ramus Intermiedius and discrete lesion of mid PDA. SCAD (spontaneous Coronary dissection) of Ramus Intermedius and mid PDA (posterior descending artery) was suspected, and patient was treated conservatively. Repeat coronary angiography, few months later showed complete resolution of SCAD with normal appearance of affected vessels. [Formula presented] [Formula presented] [Formula presented] Interventional Management Procedural Step: After obtaining an informed consent right Radial access was achieved with 6F Terumo sheath using over the wire technique. 1% lignocaine was used as local anaesthetic. 5F JL 3.5 (Judkin's) and JR 4 catheters were used to engage left main stem (LMS) and right coronary artery (RCA) and selective coronary angiography was performed. No percutaneous coronary intervention was performed. After the procedure hemoband (TR band) was applied to access site. Patient remained hemodyanamically stable throughout the procedure. [Formula presented] [Formula presented] [Formula presented] Conclusion(s): SCAD is a potential cause of type II myocardial infarction in patients with COVID-19, but more studies are needed to establish causality. Infection-related SCAD may occur at any time during index events and could be difficult to diagnose. Conservative management seems like a safe strategy.Copyright © 2023

Early detection of recurrent HPV+ hypopharyngeal squamous cell carcinoma by circulating tumor DNA

Circulating tumor DNA is a liquid biomarker that offers a highly specific method to assess HPV-associated tumor burden via a blood draw. It has the potential for many clinical applications in cancer care, including prognostication, monitoring treatment response, and surveillance for disease recurrence. In this case report, we present a case of recurrent HPV-associated hypopharyngeal squamous cell carcinoma first detected by circulating tumor HPV DNA that demonstrates the role of circulating tumor HPV DNA tests in posttreatment surveillance and the utility of HPV testing in all HPV-mediated tumors, regardless of subsite.Copyright © 2023 Elsevier Inc.

Comparing the emotional experiences of students in similar dissection- and prosection-based medical gross anatomy courses: A mixed-methods study.

The anatomy laboratory can incite strong emotional reactions in students, which can in turn facilitate growth in empathy, care for vulnerable others, and professionalism. Despite this, little is known about the relative emotional impacts of different laboratory modalities. The response to the COVID-19 pandemic created an opportunity to compare the emotional experiences of students in similar courses in which one group of students dissected donors and the other group learned from prosected donors. The courses were otherwise the same in content, length, instructional design, and assessment. Students in the dissection-based (Fall 2019) and prosection-based (Fall 2020) courses completed a previously validated survey that used quantitative and qualitative questions to assess their feelings about the donors and the anatomy laboratory experience. Students in both cohorts reported overall appreciation for having had the experience. Negative themes experienced by both groups included feeling anxiety, worries about depersonalizing donors, and physical discomfort in the laboratory. Students in the dissection course reported stronger connections with the donors and the donors' families but also more frequently felt negative feelings such as disgust, anxiety, and feeling alone. Students in the prosection course reported more consistently positive responses but worried about not using the donors to the fullest extent possible. Regardless of pedagogical design, students have complex emotional experiences in the anatomy laboratory and our results indicate that these feelings may be more intense in the context of dissection. Anatomists should foster educational settings that enable students to learn to process complex or challenging emotions.
