Slow to Respond: A Rapidly Progressive Case of Sporadic Creutzfeldt-Jakob Disease.

Creutzfeldt-Jakob disease (CJD) is a rapidly progressive, fatal neurodegenerative disorder caused by prion proteins. In about 85% of patients, CJD occurs as a sporadic disease with no recognizable pattern of transmission. Sporadic CJD (sCJD) can present with rapid cognitive and functional decline, memory deficits, myoclonus, pyramidal and extrapyramidal signs, and visual deficits. The large spectrum of phenotypic variability has made the recognition of prion diseases difficult, and given the rare incidence, it is not uncommon for it to be missed as a potential diagnosis. We present a highly unusual case of a 76-year-old woman with rapidly progressive sCJD who died within five weeks of presentation. Our case demonstrates a typical sequence of symptoms, with rapidly progressive dementia and cerebellar signs at disease onset and myoclonus later in the disease course.

New-onset seizures: an unusual neurologic manifestation of rheumatoid arthritis.

Rheumatoid arthritis (RA) is a chronic inflammatory condition primarily affecting the musculoskeletal system but can often involve other organ systems as well. Rheumatoid meningitis is a rare central nervous system (CNS) manifestation of RA characterized by pachymeningeal and leptomeningeal enhancement. Herein, we present a case of a 64-year-old male who presented with left lower extremity weakness and witnessed seizures. The diagnostic work-up, including lumbar puncture, brain MRI and meningeal biopsy ruled out malignancy and were consistent with the diagnosis of rheumatoid meningitis. The patient was discharged on high-dose steroids along with anti-seizure medications. On subsequent follow-up visits, the patient remained seizure-free.

Left Ventricular Pseudoaneurysm: A Rare but Fatal Complication of Myocardial Infarction.

Left ventricular pseudoaneurysm is a ventricular free wall rupture contained within the adjacent adherent pericardium or scar tissue. Myocardial infarction (MI), cardiac surgery, and chest trauma are the common causes. The most common presenting symptoms of pseudoaneurysms are congestive heart failure, chest pain, and dyspnea, but a small percentage of patients may be asymptomatic. Early diagnosis and treatment are of prime importance because of the tendency of pseudoaneurysms to expand and rupture, with a high mortality rate, especially if left untreated. We present a case of a 65-year-old man who was found to have left ventricular pseudoaneurysm on a follow-up echocardiography within three weeks of an MI. He subsequently underwent patch repair and was discharged after medical optimization. Our case highlights the importance of maintaining a high clinical suspicion of pseudoaneurysm in a patient post-MI, as delayed diagnosis and treatment can be fatal.

Lupus Podocytopathy: A Rare Cause of Nephrotic Syndrome in Patients with Systemic Lupus Erythematosus.

Lupus podocytopathy, a unique form of lupus nephritis, mimics minimal change disease (MCD) or primary focal segmental glomerulosclerosis (FSGS) and represents approximately 1% of lupus nephritis biopsies. Lupus podocytopathy is characterized by diffuse epithelial cell foot process effacement without immune complex deposition or with only mesangial immune complex deposition. We present the case of a young woman with systemic lupus erythematosus (SLE) who presented with nephrotic syndrome and acute kidney injury (AKI) and was subsequently diagnosed with lupus podocytopathy.

Granulomatosis with polyangiitis mimicking COVID-19 pneumonia: A case report.

Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a necrotizing vasculitis characterized by small-to-medium-sized vessel involvement and the presence of antineutrophil cytoplasmic antibodies (ANCA). We present a case of a 26-year-old Asian woman who was transferred to our center from a nearby hospital, where she presented with shortness of breath, tested positive for COVID-19, and was being managed for COVID-19 pneumonia. She also had hemoptysis, skin lesions, and left foot numbness. Serological markers and VATS-guided lung biopsy confirmed the diagnosis. Treatment with methylprednisolone and rituximab led to stabilization, despite complications of subcutaneous emphysema and lower extremity neuropathic symptoms. Early recognition and appropriate management of GPA are crucial for optimal outcomes.

Third-Degree Heart Block in COVID-19 Pneumonia Complicated by Methicillin-Resistant Staphylococcus Aureus (MRSA) Bacteremia. A Case Report and Review of Literature.

Coronavirus disease 2019 (COVID-19) burden has been identified to cause multiorgan damage. Respiratory compromise is still one of the most common presentations, but cardiac injuries like myocardial injury, ischemia, and conduction abnormalities are also becoming prevalent. We present a case of an 87-year-old male with a history of dementia, type 2 diabetes mellitus, hypertension, chronic kidney disease, and a left kidney transplant hospitalized for respiratory distress and generalized tonic-clonic seizures. He was bradycardic to 27 beats per minute, hypotensive with mean arterial pressure <60 mm Hg. An electrocardiogram (EKG) depicted a high-grade atrioventricular block (AV-block). The transvenous pacemaker was placed via femoral access and tested positive for COVID-19. Work-up was done to rule out possible causes of bradycardia, like hypothyroidism, ischemia, AV nodal blocking agents, and drug-induced bradycardia was negative. His hospital stay got complicated by methicillin-resistant staphylococcus aureus (MRSA) pneumonia leading to empyema and bacteremia. Unfortunately, being critically ill, the family opted for comfort measures, and he passed away. Our clinical vignette signifies cardiovascular complications in COVID-19 patients are associated with poor outcomes if not addressed. The conduction abnormalities in patients with intact cardiac structure and function are becoming more common in the setting of COVID infection. Assessment with serial EKGs and cardiac monitoring might be essential as patients can develop AV blocks at any point of the disease.

Paradoxical Thromboembolic Ischemic Stroke Following Tissue Plasminogen Activator Instillation for Clogged Central Venous Dialysis Catheter.

Central venous catheters including dialysis catheters are a potential source of venous thrombosis and pose a risk for paradoxical embolic events including ischemic stroke and systemic embolism in patients with a patent foramen ovale (PFO). The adult population with a PFO and patients with a central venous dialysis catheter (CVDC) are at increased risk of a paradoxical embolic event. Since bubble study is not routinely done during echocardiogram in a patient with CVDC, it is difficult to identify at-risk patients for paradoxical embolic events during catheter manipulation, especially for clogged CVDC. We report a rare case of a 79-year-old lady with end-stage renal disease on hemodialysis (HD) using a CVDC who developed a paradoxical embolic ischemic stroke following the use of tissue plasminogen activator (tPA) for unclogging a dialysis catheter. We aimed to highlight the existing risks of thromboembolism associated with the long-term use of central CVDC, especially the potential risk of paradoxical embolism and ischemic stroke with the use of tPA for management of clogged dialysis catheters. We emphasize the questionable need for a bubble study echocardiogram in all patients requiring long-term dialysis catheters.
