Optic Neuritis in Resolving Phase of COVID-19 Infection and Its Management: A Case Report.

Optic neuritis is assumed to be immune-mediated, although the specific antigens that cause demyelination are uncertain. Systemic T-cell activation is detected at the onset of symptoms, which occurs before alterations in cerebrospinal fluid (CSF). The optic nerve disease is a rare disease and can occur in one or both eyes, especially in those with no established inflammatory or autoimmune illnesses.

Thrombotic Microangiopathy Causing Acute Kidney Injury in a COVID-19 Patient.

Acute Kidney Injury (AKI) in COVID-19 patients is common and independently associated with higher mortality. The pathophysiology of AKI is multifactorial and may be either direct viral trophism or immune mediated injury and hypercoagulability. This case highlights AKI in a young female with severe COVID-19 due to complement-3 mediated thrombotic microangiopathy with pre-existing chronic kidney disease likely because of IgA nephropathy.

Transient Myelin Oligodendrocyte Glycoprotein Antibody-positive Acute Disseminated Encephalomyelitis Following Influenza A Infection: A Rare Case.

Acute disseminated encephalomyelitis (ADEM) is an uncommon disease generally with a preceding history of infectious illness. Here, we report a rare case of ADEM following influenza A infection with transient detection of anti-myelin oligodendrocyte glycoprotein (MOG) antibody in a young male patient who presented with extensive demyelination of brain and spinal cord, likely the result of dysregulated immune response from previous influenza A infection. The patient presented to the emergency with urinary retention and progressive ascending weakness of lower limbs.

Euglycemic diabetic ketoacidosis: A missed diagnosis.

Euglycemic diabetic ketoacidosis (DKA) is an acute life-threatening metabolic emergency characterized by ketoacidosis and relatively lower blood glucose (less than 11 mmol/L). The absence of hyperglycemia is a conundrum for physicians in the emergency department and intensive care units; it may delay diagnosis and treatment causing worse outcomes. Euglycemic DKA is an uncommon diagnosis but can occur in patients with type 1 or type 2 diabetes mellitus.

Cardioembolic Stroke with Peripartum Cardiomyopathy: An Unusual Presentation.

Cardioembolic stroke in a patient with peripartum cardiomyopathy (PPCM) patient is rare despite a higher incidence of thromboembolic events. We report a case of acute right middle cerebral artery territory cardioembolic stroke in a postpartum female as the initial presenting feature of PPCM. The patient was thrombolyzed with intravenous alteplase and had an almost complete neurological recovery.

Percutaneous Tracheostomy in COVID-19 Patients: A Four-step Safe Protocol.

Background: Coronavirus disease-2019 (COVID-19) pandemic has inundated healthcare systems globally especially resources in intensive care units (ICUs). Tracheostomy may be required in critically ill COVID-19 patients to facilitate weaning and to optimize resources like ventilator and ICU beds. Percutaneous tracheostomy (PCT) has become the standard of care globally in ICUs; however, it is considered a high-risk procedure in COVID-19 patients because of the inherent risk of aerosol generation.

Tocilizumab Use in COVID-19 Cytokine-release Syndrome: Retrospective Study of Two Centers.

Introduction: Cytokine-release syndrome (CRS) in COVID-19 patients can cause multiorgan failure and higher mortality. We used a structured protocol based on clinical, biochemical, and interleukin 6 (IL-6) criteria for the identification of the subset of patients with CRS and analyzed the use of tocilizumab for their treatment.

Materials And Methods: We did a retrospective case-control analysis of all COVID-19 patients between 15 March and 15 May 2020 with severe to critical disease in ICU.

Validation of RP-HPLC Method for Simultaneous Quantification of Bicalutamide and Hesperetin in Polycaprolactone-Bicalutamide-Hesperetin-Chitosan Nanoparticles.

Bicalutamide is a non-steroidal anti-androgen drug used for the treatment of androgen-dependent prostate cancer. Hesperetin is a natural bioflavonoid that can be used in combination with bicalutamide to improve efficacy and decrease tolerance. The aim of the present work was to develop and validate a simple, sensitive, rapid reverse phase-high performance liquid chromatographic method for simultaneous estimation of bicalutamide and hesperetin.
