Phenazopyridine-Induced Methemoglobinemia in a Jehovah's Witness Treated with High-Dose Ascorbic Acid Due to Methylene Blue Contradictions: A Case Report and Review of the Literature.

Methemoglobinemia is an acute medical emergency that requires prompt correction. Physicians should have a high degree of suspicion of methemoglobinemia in cases that present with hypoxemia that does not resolve with supplemental oxygenation, and they should confirm this suspicion with a positive methemoglobin concentration on arterial blood gas. There are multiple medications that can induce methemoglobinemia, such as local anesthetics, antimalarials, and dapsone.

Acquired Factor X Deficiency without Amyloidosis Presenting with Massive Hematuria: A Case Report and Review of the Literature.

Acquired factor X deficiency is a rare diagnosis, especially without the association of other co-existing conditions such as amyloidosis. The authors report the case of a 34-year-old male with severe frank hematuria found to have markedly prolonged prothrombin time and activated partial thromboplastin time. A mixing study showed correction utilizing normal plasma and a coagulation panel testing revealed decreased factor X activity.

Testosterone Usage Leading to Pulmonary Embolisms and Deep Vein Thrombosis: A Case Report and Review of the Literature.

Androgen usage has widely increased in recent times via prescribed and unprescribed means. Testosterone is a popular androgen taken by both athletes and the general population. While there is some evidence of androgens being thrombogenic, we report on a 19-year-old male who presented to the hospital after the usage of testosterone for one month, leading to the development of multiple pulmonary emboli and deep vein thrombosis.

Coronavirus disease 2019-associated nephropathy in an African American patient: a case report and review of the literature.

Background: Acute kidney injury is now recognized as a common complication of coronavirus disease 2019, affecting up to 46% of patients, with acute tubular injury as the most common etiology. Recently, we have seen an increase in cases of collapsing glomerulonephritis in patients with coronavirus disease 2019, also known as coronavirus disease 2019-associated nephropathy. It has been noted to be seen with a higher incidence in African American patients who are carriers of the APOL1 variant allele.

Diabetic Ketoacidosis as the Initial Presenting Symptom of Pancreatic Adenocarcinoma: A Discussion about Screening Utilizing ENDPAC Scoring Coupled with CT Scans and Endoscopic Ultrasound.

Pancreatic adenocarcinoma is often discovered at an advanced stage due to a lack of early symptomology, resulting in this being the fourth leading cause of cancer-related death in the USA. The relationship between diabetes mellitus and pancreatic cancer has been known for many years; however, it is not well understood. Studies have suggested that long-standing type 2 diabetes mellitus can increase the risk of pancreatic cancer by 1.

Acute Hyperhemolysis Syndrome in a Patient with Known Sickle Cell Anemia Refractory to Steroids and IVIG Treated with Tocilizumab and Erythropoietin: A Case Report and Review of Literature.

Patients with sickle cell anemia often receive multiple red blood cell (RBC) transfusions during their lifetime. Hyperhemolysis is a life-threatening phenomenon of accelerated hemolysis and worsening anemia that occurs when both transfused RBCs and autologous RBCs are destroyed. The level of hemoglobin post-transfusion is lower than pre-transfusion levels, and patients are usually hemodynamically unstable.

The Development of Immune Thrombocytopenia Due to COVID-19 Presenting as Menorrhagia.

Immune thrombocytopenia (ITP), also known as immune thrombocytopenic purpura, is a hematological disorder characterized by a decreased platelet count, predisposing patients to bleeding. Coronavirus disease 2019 (COVID-19) has been linked to multiple cases of newly diagnosed ITP and is usually found in moderate-to-severe infections, peaking in children and elderly adults. Menorrhagia is the medical term for menstrual periods with abnormally heavy or prolonged bleeding occurring at regular intervals or prolonged uterine bleeding lasting more than seven days.

Cyclical Thrombocytopenia Synchronized With the Patient's Menstrual Cycle Treated With Danazol.

Cyclical thrombocytopenia (CTP) is a very rare condition and often misdiagnosed as immune thrombocytopenia (ITP) due to similar features existing between the two. When evaluating a patient for the possible diagnosis of ITP, CTP must be high on the differential diagnosis. The main difference between the two conditions is that CTP is usually unresponsive to the treatment given to ITP and will ultimately display a cyclical nature with periods of low, normal and elevated platelets.

Hyperleukocytosis and Pseudohyperkalemia in a Patient With Severe SARS-COVID 19 Unmasks Chronic Lymphocytic Leukemia.

Coronavirus disease 2019 (COVID-19) has caused significant morbidity and mortality in a vast majority of the patient population, especially those with malignancies. Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults and is often an indolent disease. High white blood cell counts greater than 120 k/cumm in chronic lymphocytic leukemia may be implicated in cases of COVID-19.

Disseminated Intravascular Coagulation Due to Drinking Tonic Water.

Quinine has been used worldwide to treat malaria; however, it is now used as an agent for night-time muscle cramping. The compound, derived from Cinchona tree bark, is found in antimalaria medication, supplements for leg cramping, and beverages such as tonic water and bitter lemon. Quinine, however, is not without its side effect profile which includes a wide range of ailments ranging from nausea to disseminated intravascular coagulation.
