Introduction: Sickle cell disease mainly affects African Americans, and studies on racial differences in sickle cell disease outcomes are scanty. This study examined racial and ethnic differences in sickle cell disease prevalence, comorbidities, and outcomes. Methods: Using the National Inpatient Sample database from 2016 to 2018, we identified patients' records with a diagnosis of sickle cell disease using the International Classification of Diseases, Tenth Revision codes. The overall study population was further stratified by race into Blacks, Whites, and Hispanics. Using logistic regression, comorbidities and outcomes among sickle cell disease patients were compared between the three races/ethnicities. Results: Of the 74 817 hospitalized for sickle cell disease, 69 889 (93.4%) were Blacks, 3603 (4.8%) were Hispanics, and 1325 (1.8%) were Whites. Compared to Whites, Blacks were more likely to have significantly higher odds of sickle cell crisis
Patient: Male, 20-year-old Final Diagnosis: Mediastinal yolk sac tumor • yolk sac tumor Symptoms: Chest pain • cough • sensation of fullness in the neck Medication: — Clinical Procedure: Mediastinal biopsy Specialty: Cardiology • General and Internal Medicine • Oncology • Pathology Objective: Rare disease Background: Mediastinal masses can originate from anatomical structures normally located in the mediastinum, or from structures that travel through the mediastinum during embryogenesis. Initial presenting symptoms usually vary from shortness of breath, cough, chest pain, and superior vena cava syndrome to nonspecific constitutional symptoms (eg, fever, weight loss, fatigue). However, the initial presentation of a mediastinal mass with acute pericarditis has not been reported in the literature as far as we know. Case Report: A 20-year-old man presented to the Cardiology Clinic with chest pain and new pericardial effusion on echo-cardiography, both fulfilling the diagnostic criteria of acute pericarditis. The patient also had venous engorgement on the neck, and a chest X-ray followed by computed tomography imaging showed a large mediastinal mass. The serum tumor marker α-fetoprotein (AFP) was markedly elevated. The biopsy and immunohistochemistry revealed a high-grade malignant neoplasm – yolk sac tumor, which is a type of non-seminomatous germ cell tumor. The acute pericarditis resolved after administration of NSAID and colchicine. The patient was then started on chemotherapy. Conclusions: The discussed case shows the rare presentation of an anterior mediastinal mass with acute pericarditis. This emphasizes the importance of a thorough review of systems and critical analysis of every sign and symptom at the time of initial presentation, which helps the physician to obtain appropriate imaging studies early in the course, leading to an early diagnosis and treatment of the disease, such as in this case of an extremely rare germ cell tumor.
Plasmablastic lymphoma (PBL) is a rare but aggressive subtype of diffuse large B-cell lymphoma (DLBCL). The diagnosis of PBL is challenging as its features overlap with lymphoma and myeloma. The most common presentation involves the oral cavity/jaw in human immunodeficiency virus (HIV)–positive patients. It has also been reported in the gastrointestinal (GI) tract, lymph nodes, and soft tissues. Usually, if PBL involves the GI tract, it presents as a gut tumor mass. In this report, we present an HIV-positive patient with PBL presenting with multiple peritoneal nodules. To our knowledge, this is the first case of PBL presenting as multiple peritoneal and retroperitoneal nodules in an HIV-positive patient. This case emphasizes the rare presentation of a rare malignancy, difficulties in establishing a diagnosis, and the importance of proper and timely management.
Hepatocellular carcinoma (HCC) is the most common primary hepatic cancer. Although it usually presents as a liver mass, rarely HCC can have an initial presentation at an extrahepatic site before the diagnosis of the primary lesion in the liver. Even rarely was that brain metastasis as initial extrahepatic presentations. Furthermore, the initial presentation of HCC as brain metastases has been with most cases being secondary to hepatitis-related hepatoma. In this case report, we are presenting a rare and unusual case of hemorrhagic cerebral metastasis as an initial extrahepatic presentation of an alcohol-related hepatoma. Our case is the second case in the English literature that has been presented in such a way. Due to the uncommonness of presentation, there can be diagnostic dilemmas and delay in treatment. Therefore, a high level of suspicion is needed in the high-risk patients of HCC who present with unexplained or new neurological signs and symptoms. More exploration is warranted for clinical research and treatment guidelines for brain metastases of HCC to help improve survival and quality of life.
Jod-Basedow phenomenon (JBP) is a rare thyrotoxic condition due to increased exogenous iodine exposure, also known as iodine-induced hyperthyroidism (IIH). Historically JBP was typically seen in iodine-deficient patients when exposed to increased amounts of iodine. However, in today's era, the most common cause of JBP is exposure to iodinated contrast media commonly used in various radiological examinations and interventional procedures, resulting in massive iodine exposure. Patients with normal thyroid function usually experience no ill effects. There has been increasing use of iodinated contrast in imaging and procedures over recent decades. Deposition of iodine in the thyroid in a person with normal functioning thyroid glands would usually be autoregulated and inhibited by the Wolff Chaikoff effect. However, a small albeit a significant portion of patients, particularly those with pre-existing thyroid conditions, can escape this auto-regulatory effect and be subject to life-threatening conditions, such as arrhythmias, heart failure, pulmonary arterial hypertension, cerebrovascular and pulmonary embolism, and cardiomyopathy. We present a case of a 59-year-old female with pre-existing goiter who presented with altered mentation and seizures, requiring endotracheal intubation for airway protection. She underwent a CT angiogram of the head and neck for a suspected stroke, receiving iodinated IV contrast in the process. Thyroid function tests on admission showed a thyroid-stimulating hormone (TSH) of 0.974 mIU/L (reference range 0.465-4.650 mIU/L) and free T4 of 0.46 ng/dL (reference range 0.75-2.19 ng/dL). The ensuing ICU course was complicated by thyrotoxicosis eight days after contrast administration with a surge of free T4 from 0.46 ng/dL on admission to 4.07 ng/dL and a TSH suppression to <0.015 mIU/L. She subsequently required three sessions of emergent plasmapheresis to remove excess free T4 before undergoing partial thyroidectomy and cardiac catheterization. Iodine-induced hyperthyroidism solidifies the need for awareness of a potential JBP following contrast administration, especially in an aging population and undiagnosed thyroid conditions, and timely diagnosis and intervention can greatly influence outcomes.
