A Case of Chronic Myelomonocytic Leukemia Unmasked After Receiving J&J COVID-19 Vaccine.

Chronic myelomonocytic leukemia (CMML) is a clonal hematopoietic stem cell disease that comes under the overlap syndrome (myelodysplastic and myeloproliferative disorders). CMML is characterized by peripheral blood monocytosis and bone marrow dysplasia. The pathogenesis of CMML is poorly understood.

Cardiac Tamponade Associated with Human Immunodeficiency Virus-Associated Immune Complex Kidney Disease.

Cardiac tamponade is a life-threatening emergency, characterized by rapid accumulation of pericardial fluid. There are multiple risk factors for cardiac tamponade, nephrotic syndrome is an uncommon one, especially in adults. Herein, we are reporting a 35-year-old African American woman with membranoproliferative glomerulonephritis secondary to human immunodeficiency virus-associated immune complex kidney disease (HIVICK), who presented with cardiac tamponade.

Cryoglobulinemia unmasked by nivolumab in a patient with hepatitis C-induced hepatocellular carcinoma: A case report and literature review.

Hepatocellular carcinoma (HCC) is ranked the fifth-most common cancer in men and ninth most common cancer in women. Immunotherapy has been shown effective in malignancies refractory to chemotherapy and has been used as a second-line therapies in many advanced cancers, including HCC. The advent of immunotherapy has resulted in a brand-new set of side effects, and it has been proposed that it was related to over activated immune system.

Left ventricular thrombus complicated by acute limb ischemia in a patient with HIV.

Left ventricular thrombus typically occurs in patients with impaired left ventricular function such as aneurysm, dilated cardiomyopathy, or post-myocardial infarction. Untreated HIV infection is known to increase the risk of venous thromboembolism and cardiovascular disease. However, the pathophysiology remains uncertain; some studies have proposed chronic inflammation as the underlying etiology.

Diffuse bone metastasis from cholangiocarcinoma involving the sternum: A case report and review of literature.

Cholangiocarcinoma (CCA) is a rare cancer of the bile duct epithelial cells and it commonly spreads to the regional lymph nodes, liver, and lungs. Bone metastasis has been reported in patients with CCA, involving both the axial and appendicular skeleton. Herein, we report a case of extrahepatic CCA with extensive bone metastases involving the calvarium, sternum, bilateral ribs and scapulae, entire spine, pelvis, and bilateral femur.

An Unusual Presentation of Aggressive Primary Invasive Adenocarcinoma of Lung.

Bilateral diffuse infiltrates on chest imaging can present a diagnostic challenge due to a broader differential diagnosis which includes pulmonary and non-pulmonary causes. Malignancy is generally not considered under differential diagnosis at the time of initial presentation. Here we present a case of primary adenocarcinoma of lung manifesting as diffuse bilateral infiltrates on imaging.

Clinical characteristics and outcome in patients with combined diabetic ketoacidosis and hyperosmolar hyperglycemic state associated with COVID-19: A retrospective, hospital-based observational case series.

Aim: One of the risk factors for poor outcome with SARS-CoV-2 infection is diabetes mellitus; diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic state (HHS) are the most serious complications of diabetes mellitus. We aimed to explore the clinical characteristics and outcomes of COVID-19 patients presenting with combined DKA/HHS to our institution.

Methods: A retrospective, hospital based observation case series was performed on patients with SARS-CoV-2 admitted to Intensive Care Unit between 3/20/2020 and 4/20/2020.

Hyperprogressive Disease in an Advanced Stage Colon Cancer Patient on Pembrolizumab: A Case Report.

The emergence of immune checkpoint inhibitors (ICIs) in recent years has transformed the landscape of the management of solid tumors. The advancement of immunotherapy has resulted in a brand new set of adverse outcomes not previously seen in classical chemotherapy. One such adverse effect has been termed as hyperprogressive disease (HPD), a phenomenon characterized by rapid tumor progression, which often leads to devastating outcomes.

Acute upper limb ischemia in a patient with COVID-19.

Patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection mainly present with upper and lower respiratory tract symptoms, with complications related to cytokine storm syndrome and acute respiratory distress syndrome. It has also been described to predispose to venous and arterial thromboembolism; however, limited published data is available regarding thrombosis in coronavirus disease 2019 (COVID-19). Here we are presenting a case of arterial thrombosis in a patient with COVID-19 and a systematic review on coagulopathy associated with COVID-19.

A Rare Case of Severe Starvation-induced Ketoacidosis in a Patient with Recurrent Pancreatitis.

Starvation-induced ketoacidosis in non-diabetic and non-pregnant, otherwise healthy patients is not common. In an otherwise normal healthy individual, short-term starving will only result in mild ketosis. Nonetheless, the effects of ketosis can become more severe if there is stress and insulin resistance, such as in pregnant or lactating woman or in very young individual such as neonates.
