General Anesthesia Strategies for Safe, Rapid Recovery, Fast Turnaround, and Same-Day Discharge for Complix Abalations in the Ep-Specialized Asc Setting

Background: Many EP procedures are moving from the hospital to the ambulatory surgery center (ASC) outpatient setting. The COVID-19 pandemic and the CMS Hospitals Without Walls (HWW) program has been an impetus in accelerating this transition. Anesthesia provider perioperative management is critical in facilitating safe procedures with rapid, same-day discharge. Our EP-dedicated 2-OR ASC completed more than 3,000 procedures and more than 500 left-sided ablations utilizing general anesthesia with endotracheal intubation with same-day discharge. To our knowledge, this experience is unique within an ASC setting in both volume and complexity. Objective(s): We present our comprehensive anesthesia strategy and lessons learned to facilitate safe, efficient procedures and discharge in an EP ASC. Method(s): A nurse anesthesiologist with more than a decade of EP-dedicated experience developed and taught a perioperative anesthesia strategy to facilitate high volume, safe and quick discharge care. Fundamental to this is the avoidance of opioids and benzodiazepines whenever possible. Propofol or general anesthesia with sevoflurane and complete reversal with sugammadex allow for quick recovery. Mandatory video laryngoscope utilization minimizes airway trauma, while liberal antiemetic use eliminates most nausea. All femoral access is device closed. Positive inotropes are used liberally during anesthetic to avoid heart failure. The goal is to deliver all patients to PACU on room air with stable hemodynamics. Anesthesia providers manage the preop and recovery area. Result(s): More than 90% of all patients undergoing general anesthesia and heparinization for left-atrial ablation were discharged home in under 3 hours. Nearly all procedures not requiring femoral access were discharged within 30-60 minutes. High procedure volumes with efficiencies far exceeding our in-hospital experience were thus facilitated with improved patient safety. Since HWW began, five patients have required transfer to the hospital without any deaths. All others were discharged same day. Conclusion(s): We suggest that a dedicated anesthesia team with a tailored perioperative anesthesia plan facilitates performing nearly all EP-related surgical procedures in an ASC. This success is facilitated by appropriate patient selection, preoperative evaluation, intraoperative care prioritizing quick return to baseline, and end-to-end anesthesia perioperative management. We believe this type of anesthesia management is critical to the transition of EP procedures to ASCs.Copyright © 2023

A Rare Case of Congenital Choledochal Cyst (CCC) Resulting in Recurrent Acute Pancreatitis in an Otherwise Healthy Young Woman

Introduction: Congenital choledochal cyst (CCC) is a rare cystic dilatation of intrahepatic or extrahepatic biliary ducts. We present a case of a type IVb choledochal cyst presenting as recurrent acute pancreatitis in a young healthy female with initial negative screenings. Case Description/Methods: An 18-year-old-female with a history of COVID-19 presented to the emergency department with one month of persistent abdominal pain, nausea, and vomiting. She was hospitalized once prior for similar symptoms and was diagnosed with acute pancreatitis. This admission, blood work showed elevated lipase, elevated liver enzymes, mild bilirubinemia with a normal lipid panel and urine was significant for infection. She received fluids, antiemetics and was started on prophylactic antibiotics for ascending cholangitis. A right upper quadrant ultrasound ruled out cholelithiasis or acute cholecystitis, but showed dilation of the common bile duct. MRCP confirmed dilation with bulbous termination in the periampullary region diagnosed as type IVb choledochal cyst. Discussion(s): CCCs are rare in Western countries with an incidence between 1 in 100,000 to 150,000. 80% of these cysts are diagnosed in patients under the age of 10. They are difficult to diagnose due to variable clinical presentations. A study of 214 CCC patients demonstrated the most common symptom was abdominal pain, followed by jaundice and fever. When cysts are found in adults, symptoms resemble atypical acute biliary tract disease. Surgical cyst removal may be needed for patients with significant risk factors such as older age and age of symptom onset, due to increased risk of malignant transformation. Longer periods of observation have been documented to be associated with an increased chance of developing late complications, such as anastomotic stricture, biliary calculi and recurrent cholangitis. Type IVb CCCs, as seen in this case, consist of multiple extrahepatic cysts and hepaticojejunostomy is the treatment. This patient's young age and recurrent acute pancreatitis combined with her lab and imaging findings strongly suggest the diagnosis of CCC. The anatomical location of the CCC impeded flow of pancreatic enzymes through the ampulla of vater, leading to recurrent pancreatitis in an otherwise healthy young female. CCC, although very rare, should be considered in the differential of acute pancreatitis when other causes such as gallstones and heavy alcohol consumption cannot be identified, as prompt diagnosis and surgical removal is imperative.

An Immunocompetent Adult With Adenovirus Hepatitis

Introduction: In the US there has been a recent outbreak of adenovirus hepatitis in the pediatric population. However, to our knowledge, there has been only one reported case of adenovirus hepatitis in an immunocompetent adult. We have identified another such case. Case Description/Methods: A 25 year old female with no medical history presented with abdominal pain, nausea, vomiting, diarrhea, and subjective fevers for two weeks and was found to have transaminitis 25-30x the upper limit of normal, which were: AST 791, ALT 542, ALP 92, and total bilirubin of 2.9. The patient reported no prior history of liver disease. She denied alcohol, tobacco, illicit drugs, or herbal medications, but did report taking acetaminophen 1500 mg daily for two weeks. Serum acetaminophen levels were normal and serum and urine toxicology were negative. US with doppler was unremarkable, CT showed cholelithiasis, MRCP showed a normal common bile duct without obstructive calculus. Autoimmune causes of hepatitis, ceruloplasmin and alpha-1 antitrypsin were all unremarkable. HAV, HBV, HCV, HDV, HEV, CMV, HSV, VZV, EBV, HIV, and COVID19 were all negative. Ultimately, the serology for adenovirus was positive. After a week of supportive treatment, the patient's labs trended down and symptoms resolved. Discussion(s): Adenovirus is confirmed by a rise in antibody titer or by virus detection. Coagulative necrosis in histopathology is a finding in liver biopsies if they are pursued in unexplained cases of liver injury. Ultimately, adenovirus hepatitis can be diagnosed once all common causes of hepatitis have been excluded. In the current outbreak, only children have been getting adenovirus hepatitis. In adults, a high prevalence of neutralizing antibodies contributes to immunity, and therefore only in immunocompromised states, do adults get such an infection. Supportive care with IV fluids, electrolyte correction, and antiemetics usually is enough with eventual symptomatic and laboratory improvement as it was for our patient. Studies have shown that extensive disease can be treated with antiviral drugs, cidofovir, and ribavirin. Our patient's history of acetaminophen use is a confounder, however, her normal serum level and her symptoms suggestive of an infectious cause made acetaminophen less of a culprit. We hypothesize that our patient's use of acetaminophen when she was initially exposed to the virus is what made her susceptible to developing adenovirus hepatitis and we hope this case adds insight for clinicians dealing with future adult cases.

The headache of diagnosing cerebellitis

Case Report:We describe a case of a non-verbal 5-yearold patient with autism and global developmental delay who presented with headache, nausea, vomiting, and decreased oral intake and found to have acute cerebellar syndrome/cerebellitis secondary to COVID-19 infection. Method(s): Chart Review. Summary of Results: A 5-year-old male with autism spectrum disorder and global developmental delay presented with one week history of headache, nausea, and non-bilious, non-bloody emesis. Despite intravenous fluid resuscitation and anti-emetic treatment, the patient continued to have persistent emesis with decreased oral intake and urine output. Physical exam findings were notable for aniscoria with right pupil larger than left, fixed upward gaze deviation, horizontal nystagmus, and nuchal rigidity. Patient was able to move all extremities spontaneously with normal tone and without rigidity or hyperreflexia. A complete blood cell count was consistent with the following: WBC 17.29 K/uL, hemoglobin level 12.8 g/dL, hematocrit 38.9%, and platelet count 482 K/ uL. C-reactive protein <4.0 mg/L and procalcitonin 0.12 ng/mL. CT Head on hospital day one showed no acute intracranial abnormality. Due to the patient's acute neurological changes, MRI brain was obtained and revealed patchy areas of hyperintensity in both the cerebellar hemispheres with moderate swelling of the cerebellum causing narrowing of the posterior fossa extra-axial cerebrospinal fluid (CSF) spaces. In addition, there was obstruction of the cerebral aqueduct due to extrinsic mass effect by the swollen cerebellum. CSF studies were notable for the following: 148 total nucleated cells with 75% lymphocytes and 17% monocytes and 2 red blood cells, protein was elevated at 113 mg/dL, and glucose was normal at 52 mg/dL. Meningitis and encephalitis panel was without any acute findings. Other laboratory testing was negative for tuberculosis, syphilis, chlamydia, HIV, and EBV. The patient tested positive for COVID-19 virus about one month prior to the onset of symptoms. Imaging and laboratory results in the setting of obstructive hydrocephalus with associated symptoms of nausea, emesis, headache, and upward gaze deviation are consistent with acute cerebellar syndrome, or cerebellitis. Due to obstructive hydrocephalus and inflammation of the cerebellum, patient was started on high-dose steroids, and neurosurgery placed external ventricular drain (EVD). The patient worked closely with physical medicine and rehabilitation as well as speech therapy, physical therapy, and occupational therapy to make a full recovery following this illness. Conclusion(s): Headache, nausea, and vomiting are often seen as benign findings;however, it is important to obtain specific details regarding the timing of symptoms, especially in the setting of a non-verbal patient. Because inflammation of the cerebellum can lead to hydrocephalus and potential herniation, prompt diagnosis is crucial to prevent long term effects of cerebellitis.

Trends in low-value oncology care during the COVID-19 pandemic

Background: Low-value services, which provide minimal patient benefit while entailing costs and risks, are prevalent in cancer care. Shifts in cancer care delivery during the COVID-19 pandemic to minimize exposure provided opportunities for health systems and clinicians to prioritize higher-value over lowvalue oncology services. Methods: In this retrospective cohort study, we investigated the association between the COVID-19 pandemic period and low-value cancer care practices using administrative claims from the HealthCore Integrated Research Environment, consisting of ∼65 million members managed by 14 health plans across the US. We identified commercial or Medicare Advantage members diagnosed with breast, colorectal, or lung cancer between January 2015 and March 2021. Low-value cancer care practices were identified from peer-reviewed medical literature, including ASCO and ASTRO Choosing Wisely campaigns and evidence-based pathways. Five low-value practices were studied: (1) conventional fractionation instead of hypofractionation for early-stage breast cancer;(2) off-pathway systemic therapy;(3) non-guideline-based antiemetic use for minimal-, low-, or moderate-to-high-risk chemotherapies;(4) Positron Emission Tomography/Computed Tomography (PET/CT) instead of conventional CT for staging;and (5) aggressive end-of-life care (chemotherapy ≤14 days, multiple emergency department visits ≤30 days, ICU utilization ≤30 days, hospice initiation ≤3 days, and/or no hospice before death). We used linear probability models to evaluate the association between the COVID- 19 period (March to December 2020) and the 5 outcomes, adjusting for patient, facility, geographic and temporal characteristics. Results: Among 204,581 members (mean age 63.1, 139,488 [68.1%] female), 83,593 (40.8%) had breast cancer, 56,373 (27.5%) had colon cancer, and 64,615 (31.5%) had lung cancer. Rates of low-value care were similar in pre-COVID vs. COVID periods: conventional radiotherapy: 22.1% vs. 9.4%;off-pathway systemic therapy: 36.7% vs. 43.2%;non-guideline-based antiemetics: 61.2% vs. 58.1%;PET/CT imaging: 39.9% vs. 41.3%;aggressive end-of-life care: 75.8% vs. 73.3%. In adjusted analyses, the COVID-19 period was associated with no changes in off-pathway therapy (adjusted percentage point difference [aPPD] 0.82, SD 0.08, p = 0.33), PET/CT imaging (aPPD 0.10, SD 0.005, p = 0.83), and aggressive end-of-life care (aPPD 2.71, SD 0.02, p = 0.16). Small changes in conventional radiotherapy (aPPD 3.93, SD 0.01, p < 0.01) and non-guideline-based antiemetics (aPPD -3.62, SD 0.006, p < 0.01), were noted. Conclusions: The shock of the COVID-19 pandemic did not meaningfully change several metrics of low-value cancer care. Broader changes to payment and incentive design should be considered to turn the tide toward higher-value cancer care.

COVID-19 vaccines associated vestibular disorders: A case series and disproportionality analysis in Vigibase®

Introduction: Reports of vestibular syndrome have been associated with COVID vaccination in the recent literature. In this study, we aimed to evaluate the association between COVID-19 vaccines and vestibular disorders using Vigibase®, the WHO pharmacovigilance database. Material and methods: On January 5th, 2022, we extracted in a deduplicated dataset of VigiBase® reports of vestibular disorders for tozinameran (Pfizer®), elasomeran (Moderna®), Ad26.COV2.S (Janssen®) and ChadOx1nCov-19 (Astra-Zeneca®), using MedDRA preferred terms neuronitis vestibular, acute vestibular syndrome, vestibular disorder and the low level term vestibular vertigo. Seriousness was analyzed and reported odds ratio (ROR) were calculated. We also reviewed the management of COVID-vaccine associated vestibular disorders reported in Caen Regional Pharmacovigilance Center. Results: In Vigibase®, 226 reports of vestibular disorders were found for ChadOx1nCov-19, 40 for Ad26.COV2.S, 254 for elasomeran and 1,050 for tozinameran. The ROR were respectively 2.5 (2.2-2.8), 2.5 (1.8-3.2), 3.6 (3.2-4.0) and 7.0 (6.6-7.4). Reports were considered serious in 74.3% for ChadOx1nCov-19, 70.0% for Ad26.COV2.S, 60.6% for elasomeran and 56.01% for tozinameran. Finally, we collected 13 reports of COVID-19 vaccines associated vestibular disorders in our pharmacovigilance center. Concerning the management of those vestibular disorders, 4 patients received antiemetics, 1 received betahistine, 7 received acetylleucine, 2 received corticoids and 6 had vestibular physiotherapy sessions. After 1 month of follow-up, only one patient had recovered. Discussion/Conclusion: The Vigibase® analysis showed a statistically significant association between the 4 COVID-19 vaccines under study and vestibular disorders. Short-term anticholinergics, antiemetics, antihistamines or benzodiazepines, and a corticosteroid burst with rapid taper as well as vestibular rehabilitation are usually recommended treatments. In our case series we noticed the long duration of the symptoms despite the treatments received and the heterogeneity of the adopted therapeutic strategy. Physicians should be aware and careful of the potential association of COVID-19 vaccines and vestibular disorders. Management guidelines are needed given the wide exposure to COVID-19 vaccines.

Post Dengue Reactive Thrombocytosis-A Case Report

Dengue fever is common in tropical countries like India. Typically, dengue fever and dengue haemorrhagic fever is characterized by high grade fever with arthralgia, myalgia and headache. Leukopaenia, thrombocytopaenia, and fluid leak is the hallmark of dengue which normalises with recovery. However, it is very uncommon in these patients to progress to severe thrombocytosis. Authors hereby report an unusual case of dengue followed by severe reactive thrombocytosis. A 13-year-old male child was admitted with complaints of fever and headache for the past two days and vomiting for one day. There was right hypochondrium tenderness. Investigations revealed leucopaenia (total leucocyte count was 3500/μL), platelets count was 150×103/μL, haematocrit was 34.5%, and dengue virus antigen detection (NS1) was positive. Coronavirus Disease 2019 (COVID-19) Reverse Transcription-Polymerase Chain Reaction (RT-PCR) was negative. The patient was managed conservatively with intravenous fluid ringer lactate, acetaminophen, antiemetics and antacids. After 72 hours of discharge, patient came back with thrombocytosis. He was medicated on aspirin and the platelet count was monitored on a daily basis. The platelet count kept on increasing, and on 4th day it reached 1350×103/μL, but declined to normal (450×103/μL) over the next 10 days. Hence, aspirin was stopped. The patient was later discharged, and on follow-up the blood counts were normal.

Reducing dexamethasone antiemetic prophylaxis during the COVID-19 pandemic: recommendations from Ontario, Canada.

PURPOSE: People with cancer face an elevated risk of infection and severe sequelae from COVID-19. Dexamethasone is commonly used for antiemetic prophylaxis with systemic therapy for cancer. However, dexamethasone is associated with increased risk of viral and respiratory infections, and causes lymphopenia, which is associated with worse outcomes during COVID-19 infections. Our purpose was to minimize dexamethasone exposure during antiemetic prophylaxis for systemic therapy for solid tumors during the COVID-19 pandemic, while maintaining control of nausea and emesis. METHODS: We convened an expert panel to systematically review the literature and formulate consensus recommendations. RESULTS: No studies considered the impact of dexamethasone-based antiemetic regimens on the risk and severity of COVID-19 infection. Expert consensus recommended modifications to the 2019 Cancer Care Ontario Antiemetic Recommendations. CONCLUSION: Clinicians should prescribe the minimally effective dose of dexamethasone for antiemetic prophylaxis. Single-day dexamethasone dosing is recommended over multi-day dosing for regimens with high emetogenic risk excluding high-dose cisplatin, preferably in combination with palonosetron, netupitant, and olanzapine. For regimens with low emetogenic risk, 5-HT3 antagonists are recommended over dexamethasone.

Routine antiemetic prophylaxis with dexamethasone during COVID-19: Should oncologists reconsider?

The ongoing pandemic caused by severe acute respiratory syndrome (SARS) coronavirus type 2 (SARS-CoV-2, also known as COVID-19) has caused unprecedented strain on the global healthcare system, causing thousands of deaths worldwide. Patients with underlying conditions such as cancer are at substantial risk of acquiring and dying from this novel coronavirus. Numerous reports have shown that infection with SARS-CoV-2 causes depletion of B- and T-lymphocytes, including CD4 and CD8 T-cells, and is associated with severe illness and death and that patients with higher lymphocyte levels may have better outcomes. Dexamethasone, a widely prescribed antiemetic for acute and delayed nausea and vomiting from a variety of cancer drugs, causes B and T cell depletion, which may augment immunosuppression. Since it seems that lymphocytes are vital in the immune response to novel coronavirus, oncologists should reconsider the routine use of prophylactic dexamethasone in uninfected patients, to avoid inducing lymphopenia, which may increase risk of infection or lead to inferior outcomes if a cancer patient subsequently becomes infected. Since many cancer drugs and malignant diseases inherently cause lymphopenia, further reduction of lymphocytes with dexamethasone should be avoided if possible and if safe and effective alternative antiemetics are available during the COVID-19 crisis.
