A Case Report of Brugada Syndrome Associated With Physical Trauma.

Brugada syndrome is an autosomal dominant channelopathy that usually affects healthy young males without apparent structural heart disease. It is associated with a spectrum of variable and dynamic clinical manifestations, high risk of life-threatening ventricular arrhythmias, and sudden cardiac death. Our patient demonstrated transient and dynamic EKG changes of both type 1 (coved) and type 2 (saddleback) ST elevation, suggestive of the Brugada pattern that was associated with physical chest trauma and stressful situations. While common triggers like fever and certain drugs are well-recognized, this case illustrates the potential for physical stress and trauma to unmask or aggravate Brugada syndrome, albeit without definitive evidence for a causal link. Ultimately, this report underscores the importance of considering a broad differential diagnosis, including Brugada syndrome, in patients presenting with unexplained syncope or characteristic EKG changes, even when traditional triggers are absent.

A Rare Case of Synchronous Invasive Adenocarcinoma of the Colon and Marginal Zone Lymphoma of a Splenule Associated With Hemolytic Anemia.

This case report presents a rare and intriguing clinical scenario involving a 63-year-old male with recurrent left-sided hydroureteronephrosis, hypertension, and hyperlipidemia presenting with fatigue, dyspnea, and weight loss. Laboratory findings revealed anemia, basophilic stippling, spherocytosis, and nucleated red blood cells on the peripheral blood smear, raising concerns for hemolysis. Concomitant iron deficiency anemia led to further investigations, revealing gastritis and a colonic mass. A CT scan revealed splenomegaly with an accessory spleen. The histopathological evaluation identified splenic marginal zone lymphoma (MZL) - a diagnosis supported by flow cytometry. Simultaneously, the patient was found to have a moderately differentiated colorectal adenocarcinoma on colonoscopy. This unique case highlights a rare synchronous occurrence of invasive colonic adenocarcinoma with splenule MZL, an unprecedented finding in medical literature.

Embolic Phenomena of Libman-Sacks Endocarditis and Antiphospholipid Syndrome.

Patients with systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APS) are at high risk of developing arterial or venous thromboembolism and a state of systemic hypercoagulability. Libman-Sacks endocarditis (LSE) is a type of non-bacterial endocarditis usually seen in patients with systemic lupus erythematosus and antiphospholipid antibody syndrome. These vegetations dislodge easily and can cause profound neurological and systemic complications in the form of emboli. We describe one such case of a young woman with known SLE who presented with an acute middle cerebral artery (MCA) stroke and was found to have APS with extensive mitral valve vegetation, indicating Libman-Sacks endocarditis on echocardiography. Recognizing the increasing frequency of both APS and LSE in patients with SLE and screening patients, especially the younger population with SLE, for APS is vital. Furthermore, in those patients presenting with embolic events, echocardiography plays a key role as it can help expedite the diagnosis of LSE. Our case report also reiterates that warfarin, when compared to direct oral anticoagulants (DOAC), is superior in decreasing future embolic events.

Septic Shock Secondary to Tricuspid Valve Vegetation Requiring Surgical Debulking.

Tricuspid valve endocarditis is increasing in incidence owing to the prevalent use of intravenous substances. Although most patients respond well to intravenous antibiotics over the course of six weeks, some patients require surgical intervention. A multilayered approach to diagnosis with both transthoracic and transesophageal echocardiography (TEE) is recommended for optimal diagnosis and management. In this article, we report a case of septic shock resulting from tricuspid valve infective endocarditis in a young woman with a history of intravenous drug use who ultimately required cardiothoracic surgical intervention for tricuspid valve vegetation. The sensitivity and specificity of TEE for vegetation on the native valves are about 96% and 90%, respectively. Timely surgical intervention may increase the likelihood of tricuspid valve repair by preventing further destruction of leaflet tissue. Transthoracic echocardiogram (TTE) and TEE have complementary roles in the diagnosis and evaluation of endocarditis. With this case report, we emphasize the importance of multimodality imaging and early surgical intervention to prevent further embolism and destruction of tricuspid valve leaflet tissue.

Hyperammonemic Encephalopathy Secondary to Urinary Tract Infection.

Hyperammonemic encephalopathy (HE) refers to a clinical condition characterized by abrupt alteration in mental status (AMS) with markedly elevated plasma ammonia levels and frequently results in intractable coma and death. While hepatic cirrhosis is by far the most common etiology for hyperammonemia together with drugs such as valproic acid as well as urea cycle disorders, non-hepatic causes of hyperammonemia are rare and pose a clinical challenge. In this report, we describe a case of HE caused by obstructive urinary tract infection due to urease-producing bacteria in a 69-year-old man with two episodes of obstructive uropathy associated with AMS resolving with treatment with antibiotics and lactulose with normalization of ammonia level. We also provide a review of the literature with emphasis on the recognition of this serious entity of HE in the setting of obstructive uropathy to avoid the possible complications that include intractable coma and high mortality from this potentially treatable disorder.
