Spinal Solitary Plasmacytoma With Minimal Marrow Involvement Presenting With Epidural Spinal Cord Compression.

Solitary plasmacytoma (SPC) is a rare type of plasma cell dyscrasia characterized by the proliferation of neoplastic monoclonal plasma cells. It can involve bone or soft tissue without signs of systemic disease. The solitary bone plasmacytoma typically involves the axial skeleton, most commonly the vertebrae. This article presents a 58-year-old male with a history of Parkinson's disease, hypertension, and cervical spine degenerative joint disease. He arrived at the emergency department with severe thoracic and lumbar back pain, accompanied by numbness and weakness in both legs, which worsened with movement and deep breathing. Magnetic resonance imaging (MRI) findings revealed a sizable mass in the T11 vertebra, leading to thoracic spinal cord compression. Treatment included high-dose dexamethasone, and surgical intervention was undertaken. Subsequent pathology confirmed plasma cell dyscrasia. Radiotherapy and chemotherapy (lenalidomide and dexamethasone) were administered, resulting in no recurrence or new masses after two years. Solitary plasmacytoma is a rare disease with limited clinical trials due to the inability to accrue larger cohorts. Prompt diagnosis and staging of plasmacytomas, involving robust histopathological and radiographic methods, are needed to prevent further complications and possible progression to multiple myeloma. Radiation therapy is the primary treatment, with some studies showing the benefits of lenalidomide and dexamethasone. Further studies are needed to improve treatment options for these patients. This case report adds to the current literature the importance of a multidisciplinary approach to the treatment of SPC.

Thirty-day hospital readmission in females with acute heart failure and breast cancer: A retrospective cohort study from national readmission database.

BACKGROUND: Breast Cancer and cardiovascular diseases are amongst the two leading causes of mortality in the United States, and the two conditions are connected in part because of recognized cardiotoxicity of cancer treatments. The aim of this study is to investigate the predictors risk factors for thirty-day readmission in female breast cancer survivors presenting with acute heart failure. METHODS: This is a retrospective cohort study of acute heart failure (AHF) hospitalization in female patients with breast cancer in 2019 using the National Readmission Database (NRD), which is the largest publicly available all-payer inpatient readmission database in the United States. Our study sample included adult female patients aged 18 years and older. The primary outcome of interest was the rate of 30- day readmission. RESULTS: In 2019, there were 8332 total index admissions for AHF in females with breast cancer and 7776 patients were discharged alive. The mean age was 74.4 years (95% CI: 74, 74.7). The percentage of readmission at 30 days among those discharged alive was 21.8% (n = 1699). Hypertensive heart disease with chronic kidney disease accounted for the majority of readmission in AHF with breast cancer followed by sepsis, acute kidney injury, respiratory failure, pneumonia, and atrial fibrillation. Demographic factors including higher burden of comorbidities predict readmission. The total in-hospital mortality in index admission was 6.67% (n = 556) and for readmitted patients was 8.77% (n = 149). The mean length of stay for index admission was 7.5 days (95% CI: 7.25, 7.75). CONCLUSIONS: Readmission of female breast cancer survivors presenting with AHF is common and largely be attributed to high burden of comorbidities including hypertension, and chronic kidney disease. A focus on close outpatient follow-up will be beneficial in lowering readmissions.

Incidental Finding of Riedel's Lobe of the Liver and Intrahepatic Cholangiocarcinoma.

Riedel's lobe is a rare anatomical variant of the liver morphology with a downward tongue-like projection of the anterior edge of the right lobe. It is usually detected incidentally with abdominal imaging performed for other indications. We present a case where we found Riedel's lobe incidentally, with invasive adenocarcinoma arising from close proximity. A 64-year-old female came in with encephalopathy and was found to have a distended abdomen with tenderness. Imaging revealed a complex lobular mass in the right hepatic lobe with an elongated extension of the right lobe inferiorly consistent with Riedel's lobe. The differential considered was malignancy versus abscess. CT-guided biopsy revealed invasive adenocarcinoma consistent with intrahepatic cholangiocarcinoma, which was further supported by the presence of portocaval lymph nodes. Various studies have tried to establish an association between Riedel's lobe and the occurrence of cancer arising from the surrounding structures, primarily from liver or metastasis. This case report adds to the current literature when such an association is being studied.

Multiple Myeloma with CNS Involvement in the Form of Leptomeningeal Carcinomatosis Presenting as Vitamin B12 Deficiency.

A 75-year-old male presented with lower back pain, bilateral lower extremity weakness, decreased sensation to vibration and proprioception in lower extremities, anemia, and vitamin B12 deficiency. The MRI of the lumbar spine revealed extensive leptomeningeal carcinomatosis. Subsequently, the patient was diagnosed with multiple myeloma (MM) and B12 deficiency with negative intrinsic factor antibodies. MM can present as extramedullary hematopoiesis (EM) to involve the central nervous system (CNS). CNS involvement is rare and develops in only around 1% of MM patients. It carries a poor prognosis with less than 6 months survival. MM is thought to be associated with both B12 deficiency and pernicious anemia. Some studies have even suggested B12 deficiency as a possible marker for worsening disease and a prognostic factor. In our patient's case, he had extensive CNS involvement at diagnosis of MM with very low B12 levels. The extent of his disease with extensive CNS involvement, which carries a poor prognosis, could possibly explain the very low levels of B12. This is the first reported case of a patient presenting with B12 deficiency found to have MM with leptomeningeal carcinomatosis at diagnosis. To the author's knowledge, there is no literature investigating association between B12 deficiency at the time of diagnosis of MM with CNS complications. Furthermore, there are no established guidelines on treatment for leptomeningeal myelomatosis. We present this case with the effort to learn more about this disease in terms of response and overall survival.

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. Herein, we present a case of a 49-year-old male with a past medical history of diet controlled type II diabetes mellitus and recently diagnosed COVID-19 who presented to the emergency department with a chief complaint of nausea and vomiting. Our patient was found to have a thrombus-like appearing 1.9 cm × 1.2 cm well-circumscribed mass, attached to the greater curvature of the ascending aorta, superior to the right coronary cusp of the aortic valve almost three weeks after his initial diagnosis of COVID-19 virus.

Management of Wolff-Parkinson-White Syndrome in a Patient with Post-partum Cardiomyopathy.

Wolf-Parkinson-White (WPW) syndrome is a congenital heart condition in which the atrioventricular (AV) node is bypassed by an accessory pathway that connects the atria and ventricle directly. WPW syndrome in patients with a history of peripartum cardiomyopathy (pregnancy-related cardiomyopathy) is associated with a high risk of morbidity and mortality secondary to failure of the pump and the conduction system of the heart. Management of these cases deals with arrhythmia and systolic heart failure, which becomes more challenging in pregnant patients as it requires treatment methods that minimize risks to the fetus. We report a case of a young female patient with WPW syndrome and postpartum cardiomyopathy presenting with symptomatic arrhythmias (tachycardia).

An Unusual Presentation of Cholesterol Embolization Syndrome.

Cholesterol embolization syndrome (CES) is a rare presentation of systemic atherosclerosis, which commonly presents in patients with risk factors of coronary artery disease and usually occurs after cardiac or vascular procedures. Laboratory tests are nonspecific, and imaging studies may visualize the plaque. Management includes supportive care directed to relieve the end-organ damage. The prognosis of CES is poor, with high mortality of up to 29% if the CES resulted in atheroembolic renal disease (AERD). In our report, we present a 90-year-old Caucasian female who was diagnosed with CES and complicated with AERD. The patient did not undergo any cardiac or vascular procedures. This case highlights the importance of considering CES and AERD as a potential cause of renal failure, especially in high-risk patients, even if the patients did not have any history of cardiac or vascular intervention.

Magnetic Resonance Features of a Recent Catheter Ablation of Left Posterior Fascicular Ventricular Tachycardia.

A 71-year-old male patient with a past medical history of hypertension, hyperlipidemia, and chronic kidney disease stage II presented with a complaint of intermittent palpitations for three months and was found to have wide complex tachycardia on the electrocardiogram (ECG). The patient was given adenosine and amiodarone, following which he underwent synchronized cardioversion at 150 Joules followed by 200 Joules without successful conversion. He was subsequently initiated on lidocaine drip at the rate of 1 to 4 mg/minute to maintain adequate rhythm control, which converted him to sinus rhythm and relieved his symptoms. An eventual assessment with an electrophysiology study identified the presence of incessant left ventricular tachycardia (VT). The mechanism was confirmed to be left posterior fascicular ventricular tachycardia (LPF-VT). Successful mapping and ablation for the LPF-VT were achieved. Post-procedure cardiac MRI showed two small areas of near-transmural delayed enhancement. These areas are associated with nulled areas in the inferolateral wall at the left posterior His-Purkinje fascicle. This case highlights fascicular VT as a separate clinical entity, with its characteristic ECG features and acute MRI features after ablation.

A Case Report of Brown Recluse Spider Bite.

Brown recluse spider is a spider of the genus Loxosceles and also known as violin spider or fiddle-back spider. Brown recluse spider is characterized by having six eyes, with a pair in front, a pair on both sides, and a gap between the pairs. The other spiders have eight eyes in two rows of four. Brown recluse spider bites are challenging to verify but may be clinically diagnosed with consideration of geographic location, seasonality, and clinical characteristics. We present a case that involves a brown recluse spider bite in a 59-year-old female with malnutrition and polysubstance use who developed systemic symptoms and a dermonecrotic wound. Local wound care and intravenous (IV) antibiotics lead to clinical improvement by hospital day three, at which time the patient left against medical advice. The case highlights the challenges of diagnosing a brown recluse spider bites, particularly in a patient with multiple risk factors for necrotizing soft tissue infection. Furthermore, the present case represents one of the few case reports of a brown recluse spider bite in Michigan.

Invasive Pneumococcal Disease in a Patient With COVID-19: A Case Report.

The spread of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has resulted in a global health pandemic and caused profound morbidity and mortality worldwide. The virus is known to cause severe hypoxemic respiratory failure and has been associated with extrapulmonary manifestations and end-organ dysfunction in the setting of extensive inflammatory response. Recently, the association between COVID-19 and pneumococcal pneumonia co-infection or superinfections has gained increasing interest. In this report, we present the case of a 58-year-old man with a past medical history significant for pulmonary tuberculosis, diagnosed over two decades ago, who presented with pleuritic chest pain, myalgia, intermittent fevers, chills, and productive cough and was found to have invasive pneumococcal disease and COVID-19. To our knowledge, this is the first reported case of invasive pneumococcal infection in a patient with COVID-19.

Acute Renal Failure in a Patient With Severe Acute Respiratory Syndrome Coronavirus 2.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly infectious viral pathogen with high morbidity and mortality rate. The infection affects multiple organ systems leading to systemic organ failure. There is an increased incidence of acute kidney injury (AKI) in patients who become critically ill. In the critical care setting, the incidence of AKI has been variable amongst different studies. Patients with acute kidney injury who progress to renal replacement therapy are associated with worse outcomes. We describe a case of a 42-year-old male who presented with hypoxemic respiratory failure secondary to SARS-CoV-2 associated pneumonia. The patient was initially managed with the nasal cannula and then required high flow nasal cannula with worsening hypoxemic respiratory failure, requiring invasive mechanical ventilation. On top of worsening respiratory status, the patient developed new onset renal failure requiring hemodialysis.

Graves' Disease in a Patient With Human Immunodeficiency Virus Infection as an Immune Reconstitution Inflammatory Syndrome.

The use of highly active antiretroviral therapy (HAART) in the management and treatment of human immunodeficiency virus type 1 (HIV-1) has dramatically changed the course of the disease and improved overall survival. HAART results in significant decrease in viral load and enhancement of CD4 cells and gradual restoration of the immune system. However, a subset of patients may experience a paradoxical worsening after the initiation of HAART due to a heightened and dysregulated immune response. This phenomenon is termed immune reconstitution inflammatory syndrome (IRIS). The manifestation of Graves' disease (GD) after the introduction of HAART has been identified as IRIS manifestation in some patients. Thus, this occurrence should be suspected and further investigated in patients with HIV on antiretroviral therapy (ART) who present with symptoms consistent of hyperthyroidism to avoid overt hyperthyroidism. We report a case of IRIS associated Graves' disease. Our case adds to the very limited literature about this phenomenon.

Azithromycin-Induced Bradycardia.

Azithromycin is a broad-spectrum antibiotic of the macrolide class and has multiple effects on the cardiovascular system, including prolonged corrected QT (QTc) interval. However, there is limited literature on the association between azithromycin and bradyarrhythmias. Monitoring the patient via telemetry can detect bradycardia. The diagnosis of azithromycin-induced bradycardia is usually made by the exclusion of other causes of bradycardia. We report a case of a 44-year-old female with past medical history of obstructive sleep apnea who presented to our hospital due to polysubstance drug overdose with possible aspiration pneumonia. The patient received azithromycin and subsequently developed symptomatic bradycardia two days post-onset of antibiotic treatment. This case raises awareness amongst physicians about the possibility of azithromycin-induced bradycardia and explains the different mechanisms that can cause it.

COVID-19 and arterial thrombosis: Report of 2 cases.

The SARS-CoV-2 infection has been predominately associated with lung disease. However, emerging evidence has associated the COVID-19 infection with a hypercoagulable state. This hypercoagulable state can occur despite the use of anticoagulants and antiplatelets. In fact, it may even be the presenting symptom of COVID-19 in some patients. Thromboembolism associated with COVID-19 carries a worse prognosis and should be identified as early as possible. Therefore, we report 2 patients with arterial thrombosis in the form of limb ischemia in the setting of COVID-19.

COVID-19-Induced Hyperleucocytosis in Chronic Lymphocytic Leukaemia.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel coronavirus responsible for the current global pandemic, coronavirus disease 2019 (COVID-19). COVID-19 usually presents with respiratory symptoms but can affect multiple organ systems. A wide spectrum of complications can occur depending upon the comorbidities of patients. There is limited literature available regarding the presentation and outcome of COVID-19 in chronic lymphocytic leukaemia (CLL) patients. We report 2 cases of COVID-19-induced hyperleucocytosis (WBC count >100,000/µl) in CLL patients. LEARNING POINTS: Lymphopenia has been associated with severe disease and is a poor prognostic factor in COVID-19 infected patients; however, our cases show COVID-19-induced hyperleucocytosis (WBC count >100,000/µl)/lymphocytosis in CLL patients.Prior reports suggest that ibrutinib may have a protective effect against COVID-19 by decreasing inflammation and preventing progression to ARDS.

Pancreatic cancer presenting with pulmonary cannonball lesions.

Cannonball lesions are numerous, well-circumscribed, round pulmonary lesions and may be identified on plain radiograph or advanced imaging. This morphology can be associated with infectious causes, rheumatologic disease and metastatic disease. Classically, when cannonball lesions are associated with metastatic disease, they are seen in renal cell carcinoma and choriocarcinoma. We report a case of a 62-year-old Middle Eastern male who presented with shortness of breath, chest pain and fatigue and was found to have bilateral multiple pulmonary cannonball lesions and mass in the pancreas. Biopsy of one the lung lesions was consistent with pancreatic cancer. Our case adds to the limited literature available regarding cannonball lung lesions in the setting of pancreatic cancer. Health care providers should be aware of the various etiologies of cannonball lesions.

COVID-19-Induced Pancytopenia in a Major Molecular Response CML Patient on Dasatinib: A Case Report and Review of the Literature.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes coronavirus disease 2019 (COVID-19), has caused a global health crisis. COVID-19 can have a multifaceted presentation, and a wide range of complications and outcomes may emerge based on the severity and comorbidities of the infected patient. We report the case of a 42-year-old man with a history of chronic myeloid leukaemia (CML) on dasatinib (in major molecular response) who was diagnosed with COVID-19 and developed pancytopenia. Our case report and review of available publications add to the limited literature available regarding COVID-19 in CML. LEARNING POINTS: Our case report and review of the literature highlight the multifaceted response in chronic myeloid leukaemia (CML) patients to COVID-19 (respiratory symptoms, pancytopenia, severe haemolytic anaemia and haemophagocytic lymphohistiocytosis, disseminated erythematous papular skin rash).The rates of intensive care unit admission and mechanical ventilation support, and lengths of hospital stay were lower in COVID-19 patients with CML receiving tyrosine kinase inhibitors (TKI) compared with an age, gender and comorbidity-matched control group.Our case report and review of the literature suggest a possible protective effect of TKI therapy against COVID-19 in patients with CML.

Cocaine induced heart failure: report and literature review.

Heart failure is a complex clinical syndrome associated with high mortality and morbidity, creating a major public healthcare problem. It has a variety of etiologies, including substance abuse. Cocaine-induced cardiotoxicity is caused by direct effects of inhibition of sodium channels and indirect effects by inhibiting catecholamine uptake leading to increased sympathetic activity. Management is through the cessation of cocaine use and implantation of guideline-directed medical therapy for heart failure with the exception of beta-blockers as their safe usage is still controversial due to the risk of the unopposed alpha-adrenergic activity. Dexmedetomidine (Precedex) and Benzodiazepines (i.e., midazolam) are options for patients that demonstrate signs and symptoms of acute cocaine intoxication. If the actions of benzodiazepines fail to achieve hemodynamic stability, nitroglycerin may be used (especially in patients with cocaine-associated chest pain and hypertension). Cardiac transplantation is recommended for those who have demonstrated severe cardiovascular disease from cocaine. We present a 43-year-old male with a long-standing history of cocaine use who developed cardiomyopathy and severe acute decompensated heart failure found to have an ejection fraction of <20% admitted to the intensive care unit. He required inotropic support with milrinone and mechanical ventilation. He was later extubated and then discharged with an outpatient evaluation for a cardiac transplant.

Hepatosplenic Abscess From Klebsiella pneumoniae in Poorly Controlled Diabetic.

Invasive Klebsiella pneumoniae infection and pyogenic liver abscess in patients with underlying diabetes mellitus has been well described over the past 3 decades, predominantly in the Southeast Asian population, especially in Taiwan and Korea. K pneumoniae has now become the most common causative pathogen of pyogenic liver abscess in Asian countries. This shift from Escherichia coli to K pneumoniae may also be increasingly occurring in the United States of America and European countries. Compared with the >80% incidence described in Taiwan, the incidence in the United States is still reported to be lower, around 30% to 40%. However, as more evidence and reports come to light, it has become of prime importance to recognize Klebsiella as a significant emerging cause of metastatic infections in patients with uncontrolled diabetes in the United States and not just Southeast Asia, given the significant morbidity and mortality associated with the condition. In this article, we discuss the case of a 53-year-old African American female who presented with diabetic ketoacidosis and was subsequently found to have K pneumoniae pyogenic liver abscess primarily in the left hepatic lobe, bacteremia, and septic metastases to the spleen. She required extensive percutaneous drainage of abscesses and a prolonged course of multiple antibiotics. This case illustrates the growing incidence of invasive K pneumoniae infection in the diabetic population in the United States, and better patient outcomes from prompt recognition and treatment.

Reactive Thrombocytosis after Splenectomy in Hereditary Spherocytosis: Case Report and Literature Review.

Reactive thrombocytosis after splenectomy is a feared cause of thrombosis throughout the arterial and venous system. There are many causes of splenomegaly, ranging from cirrhosis to lymphoma to hereditary spherocytosis. In this report, we will discuss a case of reactive thrombocytosis after splenectomy in a patient with hereditary spherocytosis. Splenomegaly is a relatively common finding in HD patients, causing extravascular haemolysis and thus leading to haemolytic anaemia. Splenectomy is usually considered when patients start to manifest severe symptoms such as abdominal pain, jaundice or worsening liver function tests. Our patient was a good surgical candidate and successfully underwent splenectomy but afterwards developed arterial and venous thrombosis due to reactive thrombocytosis. An extensive hypercoagulable work-up was unremarkable. The patient was started on hydroxyurea and anticoagulation with eventual improvement of platelet levels. LEARNING POINTS: Reactive thrombocytosis can be a significant complication after splenectomy and can range from mild (500,000-700,000/mm3), to moderate (700,000-900,000/mm3), severe (>900,000/mm3) and very severe thrombocytosis (>1,000,000/mm3).The use of low-dose hydroxyurea in patients with very severe thrombocytosis can reduce the platelet count to safe levels, and thus, the risk of developing thrombosis.
