COVID-19 Presenting As Miller Fisher Syndrome in a Patient With a History of Guillain-Barré Syndrome: A Case Report.

Coronavirus disease 2019, caused by severe acute respiratory syndrome coronavirus 2, primarily affects the respiratory system. While coronaviruses are not a common cause of neurological disease, they have been reported to cause direct central nervous system infection, as well as presumed para-infectious disorders. Here we report a very rare case of SARS-CoV-2 infection presenting as Miller Fisher syndrome with positive anti-GQ1b antibodies in a patient with a history of Guillain-Barré syndrome, which was treated with IV immunoglobulin resulting in marked improvement in her symptoms.

Recurrent Dysphagia Associated with Esophageal Intramural Pseudodiverticulosis.

Esophageal intramural pseudodiverticulosis (EIPD) is a rare disorder of the esophagus characterized by the presence of outpouching flask-shaped lesions. These lesions represent false lumens that may be scattered throughout the esophageal wall. We present a rare case of EIPD complicated with esophageal strictures.

Black esophagus: a syndrome of acute esophageal necrosis associated with active alcohol drinking.

Black esophagus, also known as acute esophageal necrosis (AEN) syndrome, is a rare entity characterized by patchy or diffuse circumferential black pigmentation of the esophageal mucosa from ischemic necrosis. It may present with life-threatening upper gastrointestinal hemorrhage resulting in high mortality in immunocompromised patients. Advanced age with multiple comorbidities compounded with compromised hemodynamic states are poor prognostic factors.

Mycophenolate-induced Colitis: A Case Report with Focused Review of Literature.

Mycophenolate mofetil (MMF) is an immunosuppressive medication used for the management of various autoimmune diseases, and patients with bone marrow and solid organ transplants. Gastrointestinal side effects are seen 45% of the time and they include nausea (29%), vomiting (23%), constipation (38%), diarrhea (50%-92%), and colitis (9%). In 98% of cases, resolution of diarrhea occurs within 20 days upon discontinuation of the MMF.

Acute Pancreatitis in Pancreas Divisum Secondary to an Impacted Stone in the Minor Papilla.

Pancreas divisum is reported to occur in up to 14% of the population. The majority of patients with this congenital anomaly remain asymptomatic. Pancreas divisum can be associated with recurrent pancreatitis due to inadequate drainage of pancreatic secretions through the dorsal pancreatic duct and the minor papilla.

Bilateral Renal Infarction Secondary to Hypertrophic Cardiomyopathy.

Bilateral renal infarction is a rare phenomenon which can be difficult to diagnose because the symptoms may often mimic renal calculi, infection, muscle inflammation, genital diseases, myocardial infarction, or ischemia. We present the case of a 55-year-old male patient who presented with non-radiating, left-sided flank pain associated with nausea and vomiting. A computed tomography (CT) scan of the abdomen and pelvis with contrast demonstrated bilateral renal infarction.

Rectal Cancer in the Eye: A Case Report of Orbital Metastasis.

Orbital metastasis from colorectal cancer is extremely rare. In this case report, we describe a 48-year-old woman who presented with recurrent severe headaches and new onset constipation with no known history of cancer. After vigilant workup, imaging, and biopsies, she was diagnosed with orbital metastasis from a primary rectal carcinoma.
