Postinfarction Ventricular Septal Ruptures During the COVID-19 Pandemic: Two Case Series.

This case series highlights the occurrence of hemodynamically significant ventricular septal defects (VSDs) in two patients presenting with ST-elevation myocardial infarction (STEMI) during the COVID-19 pandemic. This paper aims to emphasize the delayed presentation of cardiac emergencies, such as STEMI, due to concerns about contracting COVID-19. This delay has led to an increased risk of rare complications, including VSD, associated with STEMI. The first case involves a 92-year-old male with a history of hypertension, hyperlipidemia, chronic kidney disease, and coronary artery disease. He presented with acute chest pain, and diagnostic tests revealed ST elevations and a VSD. Despite intervention efforts, including hemodynamic support, the patient's condition deteriorated, and he passed away due to advanced age and high surgical risk. The second case involves a 62-year-old female with a medical history of diabetes, hypertension, and hyperlipidemia. She presented with left-sided chest pain, and an angiogram revealed a mid-right coronary artery stenosis and a thrombus. During the procedure, the patient experienced hypotension, requiring hemodynamic support. Subsequent evaluations identified a large VSD with right ventricular dysfunction. The patient underwent a series of interventions, including a ventricular assist device and VSD closure, but experienced multi-organ failure and ultimately passed away. VSDs following acute myocardial infarction (MI) are rare but life-threatening complications. Early revascularization is crucial in preventing the development of VSDs. These cases demonstrate the importance of prompt diagnosis and intervention, as delayed presentation increases the risk of mechanical complications. Surgical closure remains the definitive treatment for postinfarction VSDs.

Sickle Cell Anemia Associated With Increased In-Hospital Mortality in Post-Cardiac Arrest Patients.

Introduction Sickle cell anemia (SCA) is a hemoglobinopathy that arises from a point mutation in the beta-globin gene, which causes the polymerization of deoxygenated hemoglobin that leads to a wide variety of clinical complications. Deaths in patients with SCA most commonly arise from renal, cardiovascular disease, infections, and stroke. In-hospital cardiac arrest has been found to be more common in older patients and those on ventilatory life support, among others. This study aims to provide more insight into how SCA affects the risk of in-hospital mortality in post-cardiac arrest patients. Methods The National Inpatient Survey database years 2016 to 2019 was utilized. The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10 PCS) codes for cardiopulmonary resuscitation were used to identify in-hospital cardiac arrest (IHCA) patients. ICD-10 Clinical Modification (CM) codes were used to identify SCA and other medical comorbidities. Categorical data was compared using Person's chi-square test, and continuous variables were compared using the independent samples t-test. Multinomial logistic regression was used to study the effects of SCA on post-arrest in-hospital mortality controlling for age, Charlson comorbidity score, and demographic variables. Binomial logistic regression models for dichotomous variables were utilized in the subgroup and secondary outcomes analysis. Results In patients with IHCA, patients who had SCA were found to have a significantly increased risk of in-hospital mortality adjusted for baseline characteristics and Charlson comorbidity score (OR: 1.16, 95% CI: 1.02-1.32, p=0.0025). Patient characteristics most strongly associated with an increased risk of in-hospital mortality in this cohort were found to be Black race (OR: 1.92, 95% CI: 1.87-1.97, p<0.001) and self-payer status (OR: 2.14, 95% CI: 2.06-2.22, p<0.001). Subgroup analysis revealed only patients with sickle cell disease had a statistically significant increased risk of in-hospital mortality in this cohort (OR: 4.41, 95% CI: 3.5-5.55, p<0.001), and patients with sickle cell trait did not. Conclusion In patients with IHCA, SCA is associated with an increased risk of in-hospital mortality. This risk was confined to patients with sickle cell disease and not patients with sickle cell trait.

Myocarditis as a Complication of Campylobacter jejuni-Associated Enterocolitis: A Report of Two Cases.

Myocarditis refers to inflammation of the heart muscle and may occur individually or together with pericarditis, which refers to inflammation of the saclike tissue layer that surrounds the heart. They may have infectious or non-infectious etiologies. Campylobacter jejuni, a major cause of gastroenteritis worldwide, may also cause myocarditis in rare situations. We present two cases highlighting this rare complication of diarrheal disease caused by Campylobacter jejuni infection and subsequent development of myocarditis. Both patients presented with chest pain and multiple episodes of watery diarrhea, with initial EKGs showing ST segment changes, as well as elevated inflammatory markers and elevated troponins. GI panels for both patients were positive for Campylobacter jejuni. Based on their presentations and investigative findings, they were diagnosed with myocarditis secondary to Campylobacter infection, and their symptoms subsided with appropriate management. It is unclear if the myocardial damage, in this case, is a direct effect of the toxin on cardiac myocytes or secondary to an immunologic phenomenon. Regardless, Campylobacter jejuni-associated myocarditis remains a rare phenomenon and needs to be considered in the differential of patients presenting with concurrent chest pain and diarrheal symptoms.

A Gut-Wrenching Feeling: Overcoming Cognitive Biases in an Atypical Presentation of Chronic Mesenteric Ischemia.

Chronic mesenteric ischemia is a rare but serious condition that can present with a variety of symptoms, including abdominal pain, diarrhea, and weight loss. Our case report presents a 63-year-old male with a past medical history of generalized anxiety disorder, Barrett's esophagus, hypertension, hyperlipidemia, chronic obstructive pulmonary disease (COPD) with active smoking who initially presented with severe diffuse abdominal pain, nausea, vomiting, and chronic diarrhea resulting in malnutrition and 40-pound weight loss over a six-month span. The patient underwent extensive diagnostic evaluation and was diagnosed with Yersinia gastroenteritis via gastroenteritis panel (GI Panel), explaining all of the patient's symptoms. The patient underwent treatment for said gastroenteritis but did not experience remission of symptoms, leading to further diagnostic evaluations; a definitive diagnosis was not found, yet the patient's symptoms persisted. The patient then underwent extensive serologic and endoscopic evaluation, after extensive imaging and diagnostic work-up, the patient was finally diagnosed with chronic mesenteric ischemia (CMI) of the superior mesenteric artery (SMA) with severe celiac and inferior mesenteric artery (IMA) stenosis. The patient initially underwent stenting (7 mm by 26 mm Balloon Mounted LifestreamTM Covered Stent; Becton Dickson (BD); Franklin Lakes, NJ, USA), which provided temporary relief to his symptoms, however, the relief did not last long. Upon reimaging, the patient was found to have stenosis of the stent, leading to the eventual placement of a bare-metal stent (ExpressTM LD 7 x 27 mm balloon mounted bare-metal stent; Boston Scientific; Boston, MA, USA) across the celiac artery as well as the placement of an IMA stent (InnovaTM Self-expanding 5 x 20 mm bare-metal stent; Boston Scientific). This eventually resulted in the resolution of the patient's symptoms, eventual weight gain, and improvement in quality of life.

Synchronous Liver Abscess With Cholecystitis: A Rare Case of Initial Presentation of Gallbladder Cancer Posing a Diagnosis Challenge.

Gallbladder carcinoma (GBC) is the most common of all biliary tract cancers. GBC is a multifactorial disease. Gallbladder dysplasia from any gallbladder inflammatory condition is one of the main risk factors for GBC. The late diagnosis of GBC is a major problem in its treatment. It is treated by radical resection and the prognosis is improved by adjuvant chemoradiation. We present a rare case of gall bladder cancer presenting as hepatic abscesses with severe sepsis. An 83-year-old male presented with progressive symptoms of shakiness, general weakness, vomiting, and profuse diarrhea. Lab work revealed deranged liver enzymes. Computed tomography (CT) and magnetic resonance cholangiopancreatography (MRCP) abdomen revealed intrahepatic abscesses contiguous with the gallbladder lumen through a gallbladder wall defect and cholecystitis of unknown chronicity. Subsequently, he underwent central hepatectomy and the pathology report of the sample as well as endoscopic retrograde cholangiopancreatography (ERCP) brushings revealed gallbladder adenocarcinoma. The case was complicated by biloma, acute renal failure, and the development of malignant ascites, and the patient died almost four months after the diagnosis of gallbladder cancer.

Evaluating Dental Fear and Anxiety in Pediatric Patients Visiting a Private and a Public Dental Hospital in Lahore, Pakistan.

Background One of the biggest hurdles in treating pediatric patients is managing dental fear and anxiety. Some factors that contribute to an increase in dental anxiety are fear of pain, the presence of unknown individuals, a change in the setting of an environment, and separation from parents. Aim The aim of this study was to evaluate dental fear and anxiety in pediatric patients, between the ages of 6 and 12 years, visiting private and public dental hospitals using the Children's Fear Survey Schedule-Dental Subscale (CFSS-DS). Methods A total of 280 children, 140 in a private dental hospital setting and 140 in a public dental hospital setting, were enrolled in this study. The purpose of the study was explained to the accompanying guardian of the patient and written consent was taken. The CFSS-DS was explained verbally in Urdu and the questionnaire was given to guardians alongside the patients which they were asked to fill out following their dental treatment. Result The data obtained from the questionnaires were analyzed using the unpaired t-test. The highest dental fear mean scores and standard deviation in a private dental hospital were for "choking" (3.25 ± 1.21), "the noise of the dentist drilling" (3.24 ± 1.04), and "having somebody put instruments in your mouth" (3.19 ± 1.06), whereas, for a public dental hospital, the highest fear score was recorded in "choking" (3.17 ± 1.69), "injections" (3.07 ± 1.72), and "people in white uniforms" (1.90 ± 1.21). Conclusion The study showed a higher prevalence of dental fear and anxiety in a private dental setting when compared to a public dental setting. Factors responsible for an increase in dental fear need to be assessed for each patient and then treatment given accordingly.

Remdesivir-Associated Acute Liver Failure in a COVID-19 Patient: A Case Report and Literature Review.

There is a broad classification of the causes of acute liver failure (ALF) that include drug-induced liver injury (DILI). In this report, we aim to discuss the association between remdesivir, a novel therapeutic drug for hypoxic coronavirus disease 2019 (COVID-19) pneumonia, and DILI with subsequent ALF in a patient who was recently treated with the drug in question. Remdesivir, which is a direct-acting nucleoside RNA polymerase inhibitor, is one of the only FDA-approved drugs on the market for COVID-19 pneumonia associated with hypoxia. Our case describes a patient with an extensive past medical history who was treated for COVID-19 pneumonia with remdesivir and subsequently developed ALF in the absence of all other possible etiologies. This association has only been highlighted in anecdotal case reports in the past and to a lesser degree in the safety documentation of remdesivir.

A Rare Initial Presentation of Aortic Intramural Hematoma: A Case Report and Literature Review.

Aortic intramural hematoma (AIH) is a life-threatening emergency that involves aortic wall integrity and is characterized by either a direct rupture of the vasa vasorum or spontaneous bleeding of an arterial plaque located in the tunica media of the aortic wall. A notable difference between AIH and acute aortic dissection is the absence of an intimal flap, a finding discernable on computed tomography angiography (CTA). Follow-up imaging allows for the monitoring of disease progression or early findings of impending complications. While some patients may require surgical intervention, medical management with blood pressure control remains the mainstay in treatment. Our case describes a patient who was found to be in cardiac arrest secondary to ventricular fibrillation and was then found to have presumed Stanford Type A aortic dissection on CTA. After reviewing the scans, the diagnosis was reclassified to AIH due to the absence of an intimal flap, the patient was then managed medically for AIH with antihypertensive medications.

A Rare Case of Pseudomembrane-Associated Ulcerative Colitis.

Ulcerative colitis (UC) is a chronic, life-long inflammatory bowel disease that normally presents with bloody diarrhea, fever, abdominal pain, and leukocytosis. Diagnosis is usually based on clinical presentation, endoscopy with biopsy, and exclusion of alternative diagnoses. In very rare cases, pseudomembranes may be found on colonoscopy in patients with an early UC flare. Historically, the objective finding of pseudomembranes has been exclusively used to diagnose a Clostridioides difficile infection (CDI); however, diagnostic testing must be correctly utilized to confirm whether a CDI is truly the cause of the presence of pseudomembranes, and not an alternative etiology, such as UC. In this case, we discuss a 43-year-old female who presented to the hospital with worsening chronic bloody diarrhea after being seen in the outpatient clinic for a questionable CDI. She underwent endoscopic evaluation revealing pseudomembranous colitis; however, C. difficile testing showed one positive gastrointestinal (GI) pathogen panel and multiple negative antigens and toxin enzyme immunoassays (EIA). With a clinical suspicion of early UC, the patient was treated with mesalamine enemas and improved clinically before discharge. Several months later, she underwent endoscopic evaluation with biopsy, which showed findings consistent with a diagnosis of UC.
