Severe Clozapine-Induced Agranulocytosis, Pharmacodynamic Synergism, and Lithium Promyelocytic Effects in Granulocyte Colony-Stimulating Factor (G-CSF) Resistance or Delayed Response: A Case Report.

Clozapine-induced agranulocytosis is documented in multiple studies, but there is limited literature on treatment-resistant agranulocytosis, the synergistic effect of multiple agranulocytosis-inducing drugs, and lithium's promyelocytic effects. This case highlights these gaps by discussing a patient with an absolute neutrophil count of zero while being treated with Depakote, Haldol, and clozapine. This case proposes more research on lithium's promyelocytic effects, especially in patients who are unresponsive or have a delayed response to discontinuing offending agents and granulocyte colony-stimulating factor (G-CSF).

Lupus-Induced Accelerated Heart Failure in a Young African American Female: Cardiovascular and Systemic Complications of Noncompliance to Maintenance Therapy and the Social Determinants of Cardiovascular Disease.

Systemic lupus erythematosus (SLE) is an autoimmune inflammatory disorder characterized by dysregulations of the immune system with intermittent and remitting symptoms. SLE affects multiple organs and systems, including the cardiovascular system. This condition is associated with an increased risk of cardiovascular disease, particularly in younger patients.

Molecular Mimicry: An Uncommon Occurrence of Vitamin B12 Deficiency Imitating Thrombotic Thrombocytopenic Purpura in an African American Male.

Thrombotic thrombocytopenic purpura (TTP) and vitamin B12 deficiency can share similar symptoms but require different treatment approaches. TTP is a blood disorder with a high mortality rate requiring immediate plasmapheresis treatment. On the other hand, vitamin B12 deficiency usually presents with anemia, low platelet counts, jaundice, and signs of disrupted red blood cell breakdown, resembling a condition called microangiopathic hemolytic anemia.

Where is the Thrombus ? Mural Ascending Aortic Thrombus with Embolic Events in a Patient with Recent COVID 19 Infection.

The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a global health pandemic that led to substantial morbidity and mortality worldwide. The virus has been known to predominantly cause severe hypoxemic respiratory failure but there have been multiple reports of extra-pulmonary manifestations. Additionally, there has been increasing evidence of COVID-19 hyper-coagulability.

Tricuspid Endocarditis: A Case Report and Comprehensive Literature Review.

Infective endocarditis is a multisystem disease. Tricuspid valve endocarditis is frequently seen in patients with intravenous (IV) drug users. Cavitating lung nodules predominantly in a peripheral location in IV drug users indicate the possibility of septic emboli.

Painless Presentation of a Deadly Disease: Type A Aortic Dissection Requiring the Bentall Procedure.

Unlabelled: Aortic dissection is a relatively uncommon, although catastrophic, disease which requires early and accurate diagnosis and treatment for patient survival. Aortic dissection can be difficult to diagnose due to the diverse symptom presentation, which can lead to later diagnosis, resulting in a higher mortality rate. Here we present a case of type A aortic dissection with a varied symptom presentation, highlighting the importance of early detection and the Bentall procedure for management of such cases.

5q Deletion Myelodysplastic Syndrome in a Young Male Patient.

Myelodysplastic syndromes (MDS) are a diverse group of hematopoietic stem cell malignancies with various phenotypic variability that are categorized by abnormal differentiation of one or multiple cell lines of the bone marrow. A large part of the phenotypic heterogeneity is in part due to the wide set of genetic defects related to MDS. Though clinically, MDS is centered on diagnostic measures that do not incorporate molecular genetic data, an isolated deletion of the long arm of chromosome 5 (del(5q)) is the only subset of MDS to be identified by genetic defects.

Corrected QT Interval Prolongation, Elevated Troponin, and Mortality in Hospitalized COVID-19 Patients.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has risen to the level of a global pandemic. Growing evidence has proven the cardiac involvement in SARS-CoV-2 infection. This study aims to evaluate the ability of cardiovascular complications determined by elevated troponin and electrocardiogram findings (e.
