A Rare Cause of Esophageal Dysphagia - Secondary Esophageal Tuberculosis.

Tuberculosis (TB) is an infectious disease caused by . It continues to be one of the most common causes of death in adults across all countries. It is found to be relatively lower in North America.

A possible Guillain-Barré syndrome/transverse myelitis overlap syndrome after recent COVID-19.

Neurological manifestations are common in SARS-CoV-2 infection, including life-threatening acute muscle weakness, due to neuromuscular disorders such as acute transverse myelitis (TM) and Guillain-Barré syndrome (GBS). These syndromes can rarely coexist and present as an overlap syndrome. Here, we report a patient who developed acute symmetrical proximal lower limb weakness 5 days after diagnosis of COVID-19.

Heparin-Induced Renal Tubular Acidosis Masquerading as Hyperkalemia in a SARS-CoV-2 (COVID-19) Patient: A Case Report.

Type 4 renal tubular acidosis (RTA) is a type of metabolic acidosis characterized by hyperchloremia and hyperkalemia resulting from the reduction in and/or resistance to aldosterone. RTA can be caused by multiple different medications including angiotensin-converting enzyme (ACE) inhibitor/angiotensin receptor blocker (ARB), potassium-sparing diuretics, and heparin. In this case, we discuss renal tubular acidosis caused by heparin use for the prevention of thromboembolic disease in COVID-19 infections.

Human Herpesvirus 6 (HHV-6) Encephalitis in a Non-Transplant Patient With Polymyositis.

Human herpesvirus 6 (HHV-6) was initially labeled as a human B lymphotropic virus because it was isolated in patients diagnosed with lymphoproliferative disorders. There are two variants of HHV-6: HHV-6A and HHV-6B. A considerable majority of recorded primary infections and reactivation events are primarily due to HHV-6B.
