Left Ventricular Pseudoaneurysm and Left Ventricular Thrombus in a Patient Presenting with an Acute ST-Elevation Myocardial Infarction.

BACKGROUND ST-elevation myocardial infarction (STEMI), when associated with acute left ventricular (LV) free-wall rupture, is often a lethal complication, and if not followed by sudden death, the rupture may be contained by the parietal pericardium and a local thrombus, leading to the formation of a left ventricular (LV) pseudoaneurysm. The incidence of LV pseudoaneurysm after STEMI is ~ 0.3%. CASE REPORT A 73-year-old man who presented with an acute syncopal episode and intermittent chest pain for 7 days was found to have an anterolateral myocardial infarction (MI) with lateral wall rupture and pseudoaneurysm formation. He had an LV thrombosis in the LV aneurysm. While this increased his risk of thromboembolic events, it likely stopped the evolution of the rupture and stabilized the pericardial effusion size. The patient underwent coronary artery bypass grafting (CABG), thrombectomy, and lateral wall repair. CONCLUSIONS Left ventricular pseudoaneurysm and left ventricular thrombus in a patient presenting with an acute ST-elevation myocardial infarction is a rare complication of myocardial infraction, with an incidence of <1%. It is often a lethal complication and requires stabilization and repair if not followed by sudden death.

Thrombocytopenia and endocarditis in a patient with Whipple's disease: case report.

BACKGROUND: Whipple's disease (WD) is a rare multisystem infectious disorder that is caused by the actinomycete Tropheryma whipplei. It presents with joint pain followed by abdominal pain, diarrhea, malabsorption and finally failure to thrive. Diagnosis requires tissue sampling and histology with periodic acid-Schiff [PAS] staining. Thrombocytopenia associated with endocarditis associated with WD has been reported twice. CASE PRESENTATION: A 56 year old Caucasian male presented with years of steroid treated joint pain and recent onset diarrhea, weight loss and abdominal pain. Ultimately he was found to have a platelet count of 4000 with concomitant endocarditis and embolic stroke. Small bowel biopsy confirmed the diagnosis of WD approximately 1 year after his first visit. His platelets improved with antibiotic treatment but he eventually expired 16 months after his initial consult and 5 months after his definitive diagnosis. CONCLUSION: WD can remain undiagnosed and untreated until late in the course of the illness. A high index of suspicion is recognized as necessary for early diagnosis to begin treatment. Critical thrombocytopenia associated with endocarditis is a rare and potentially poor prognostic sign in late stage Whipple's disease.

Plummer-Vinson Syndrome and Heart Failure: An Unusual Association in an African American Woman.

BACKGROUND Plummer-Vinson syndrome (PVS) is a rare disorder composed of the triad of dysphagia, iron-deficiency anemia (IDA), and esophageal webs. It is most prevalent in middle-aged white women, and the dysphagia often improves when the anemia is treated. It is well established that chronic hypertension can lead to congestive heart failure (CHF). While IDA is frequently found concomitantly with CHF, there have been no reported cases of new-onset CHF with anemia presenting as PVS. CASE REPORT We present the case of a 48-year-old African American woman with symptomatic anemia and new-onset congestive heart failure secondary to hypertension, who presented with the classic symptoms of PVS. CONCLUSIONS CHF with accompanying IDA may be an independent risk factor for the development of PVS. At the very least, there is an association between CHF-induced IDA and PVS. Patients presenting with CHF with symptoms of dysphagia should be considered at risk for the syndrome, and endoscopy may be warranted. Treatment for PVS includes iron replacement, and in some cases requires mechanical dilation.

Monotypic IgG1-kappa Atypical Anti-Glomerular Basement Membrane Nephritis: A Case Report.

Anti-glomerular basement membrane (anti-GBM) glomerulonephritis is a rare disease caused by autoantibodies against the glomerular basement membrane. Atypical anti-GBM nephritis is clinically less aggressive and characterized by the absence of circulating autoantibodies to the basement membrane. A previously healthy 53-year-old white woman presented with a rising creatinine over a short observation period. Renal biopsy, urinary sediment, and laboratory testing confirmed the diagnosis of atypical anti-GBM disease. She received plasmapheresis, steroids, and cyclophosphamide. She developed hemorrhagic cystitis early in the treatment from oral cyclophosphamide and mycophenolate mofetil was substituted as a first-line drug. She responded favorably and continued on mycophenolate mofetil without evidence of relapse. Despite the absence of circulating autoantibodies, a diagnosis of atypical anti-GBM nephritis should not be excluded if a high index of clinical suspicion exists. Early renal biopsy should be considered. Mycophenolate mofetil may be a reasonable replacement for oral cyclophosphamide in the treatment of atypical anti-GBM disease when cyclophosphamide is contraindicated.

Hemophilia A Complicated by Ulcerative Colitis.

BACKGROUND: Hemophilia A is an X-linked recessive disorder characterized by defective synthesis of Factor VIII protein. Depending on the level of FVIII activity, patients may present with easy bruising, inadequate clotting of traumatic or mild injury, or in severe hemophilia, spontaneous hemorrhage. Ulcerative colitis (UC) is an inflammatory bowel disease (IBD) that is reported to have a decreased frequency of occurrence in subjects with coagulation disorders. CASE: A 26-year-old white male with Hemophilia A was admitted for one month of rectal bleeding. The bleeding continued despite Factor VIII replacement and colonoscopy and biopsy were performed confirming the presence of active UC. CONCLUSION: Ulcerative colitis with underlying F VIII deficiency can result in serious, prolonged, and possibly fatal bleeding if left unrecognized and untreated. Treatment of both conditions concurrently utilizing tertiary facilities and consultations appears to be the safest strategy for management.
