Portal Vein Thrombosis Associated With Fusobacterium nucleatum Bacteremia: A Rare Abdominal Variant of Lemierre's Syndrome.

Lemierre's syndrome is a rare but potentially severe complication of bacterial infections that usually affects previously healthy adolescents and young adults. It commonly presents as septic thrombophlebitis of the internal jugular vein and bacteremia following a recent oropharyngeal infection. The most commonly isolated organisms are Fusobacterium necrophorum, followed by Fusobacterium nucleatum and other anaerobes. Atypical Lemierre's syndrome is characterized by thrombophlebitis at sites distant from the head and neck veins and is far less encountered than typical Lemierre's syndrome. Here, we present a case of an elderly African American female with pylephlebitis, a rare abdominal variant of Lemierre's syndrome with extensive portal vein, splenic vein, and mesenteric vein thrombosis following perforated diverticulitis and resultant F. nucleatum bacteremia. She demonstrated complete recovery following appropriate long-term intravenous antibiotics and anticoagulation. This case calls attention to the re-emergence of the rare manifestation of this forgotten disease and highlights improved outcomes with prompt recognition and early treatment.

A Rare Case of Eustachian Valve Endocarditis in a Young Male With Poorly Controlled Type 1 Diabetes Mellitus.

The eustachian valve (EV) is a vestigial structure found at the junction of the inferior vena cava and the right atrium, a remnant of the embryological sinus venosus that may persist throughout life. Right-sided infective endocarditis of the eustachian valve remains a distinctly rare and under-diagnosed entity. Commonly known risk factors of eustachian valve endocarditis (EVE) are intravenous drug use, in-dwelling intracardiac devices, and central lines, although more recently immunocompromised states, e.g. uncontrolled diabetes mellitus and old age, have been recognized as risk factors for the disease. Although Staphylococcus aureus has been the most commonly implicated organism, cases of infections with gram-negative organisms are emerging. We present a 47-year-old male with uncontrolled type 1 DM who initially presented to the ED with complaints of low back pain and dysuria and was later found to have eustachian valve endocarditis ultimately treated with intravenous antibiotics.

Acute Compartment Syndrome in the Setting of Weight Loss Supplements and Exercise-Induced Rhabdomyolysis.

The growing prevalence of obesity in the USA has resulted in increased consumption of weight loss products that promote fat metabolism. Dietary supplements used for weight loss contain a wide variety of ingredients but the amount of scientific information available on these ingredients varies considerably. Such supplements have documented and undocumented adverse effects. Although the FDA frequently issues health advisories, the health consequences of consuming supplements are often overlooked by the general public. A common supplement used for weight loss is Hydroxycut. The ingredients used in the different forms of Hydroxycut products vary but generally include caffeine and green tea extract, which are responsible for a wide range of adverse effects. We present the case of 41-year-old man with a medical history of polysubstance abuse who developed acute compartment syndrome in the setting of rhabdomyolysis from prolonged immobilisation and the use of Hydroxycut. This case demonstrates the possible adverse effects of consuming weight loss herbal supplements like Hydroxycut. Healthcare professionals and consumers are encouraged to report serious adverse events or product quality problems with the use of these supplements to the FDA's MedWatch adverse event reporting program. LEARNING POINTS: The weight loss supplement Hydroxycut is sold in various formulations whose side effect profiles are not fully known; the latest formulation has a very high concentration of caffeine which increases the risk of rhabdomyolysis.Although uncommon, exercise-induced rhabdomyolysis can cause compartment syndrome, especially in the setting of concurrent use of weight loss supplements.High clinical suspicion, prompt diagnosis and early treatment are key to preventing complications from compartment syndrome.

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.

An Atypical Presentation of Severe Dissecting Aortic Aneurysm: A Case Report and Literature Review.

A 55-year-old male patient with no past medical history presents to the ED to complain of exertional dyspnea and bilateral lower limb swelling. The patient was diagnosed with a severe dissecting aortic aneurysm on trans-thoracic echocardiography and later confirmed by a contrast CT aortogram. The patient was immediately started on anti-impulse therapy with labetalol infusion and underwent emergent aortic dissection repair. This case demonstrates an atypical presentation of a life-threatening condition that might have been missed on the initial assessment.
