ABSTRACT

BACKGROUND: Cardiac myxomas are the most common benign primary tumour of the heart. Clinical presentation is variable and ranges from constitutional symptoms to clinical features due to intracardiac obstruction, such as mitral stenosis, coronary embolization, or systemic embolization. Surgical resection is the only effective treatment to prevent its debilitating and catastrophic complication. CASE SUMMARY: A 61-year-old woman presented with an-hour history of bilateral leg pain, numbness, lightheadedness, dyspnoea, and diaphoresis. Physical exam was remarkable for pale and cold lower extremities. Arterial pulse was not palpable in the right femoral, popliteal, and posterior tibial and dorsalis pedis arteries bilaterally. Electrocardiogram demonstrated normal sinus rhythm with T-wave inversion in lead I, V2, V3, and V4. Laboratory investigations were remarkable for leucocytosis and elevated troponin. Computed tomography angiogram showed emboli with acute infarcts involving the spleen and kidneys, acute embolic occlusion of right external and internal iliac arteries, and left distal common femoral artery. She underwent emergent bilateral cut-down and femoral artery thrombectomies. Transthoracic echocardiogram demonstrated wall motion abnormalities. Computed tomography angiography of the chest revealed an atrial mass and transoesophageal echocardiography was obtained which confirmed an atrial myxoma. Coronary angiography demonstrated no significant coronary artery disease, raising the possibility of myxoma embolization to the coronary arteries as the cause of her troponin elevation and wall motion abnormality. Subsequently she underwent successful resection of the atrial myxoma. DISCUSSION: The majority of cardiac myxomas are sporadic and arise from the left atrium as an isolated lesion in middle-aged women. Echocardiography is the diagnostic procedure of choice. The long-term survival after surgical resection is excellent and recurrence is rare.

ABSTRACT

Cardio-renal syndrome is a commonly encountered problem in clinical practice. Its pathogenesis is not fully understood. The purpose of this article is to highlight the interaction between the cardiovascular system and the renal system and how their interaction results in the complex syndrome of cardio-renal dysfunction. Additionally, we outline the available therapeutic strategies to manage this complex syndrome.

ABSTRACT

Atrial fibrillation (AF) is the most common sustained arrhythmia in patients with chronic kidney disease (CKD). In this study, we examined the association between inflammation and AF in 3,762 adults with CKD, enrolled in the Chronic Renal Insufficiency Cohort (CRIC) study. AF was determined at baseline by self-report and electrocardiogram (ECG). Plasma concentrations of interleukin(IL)-1, IL-1 Receptor antagonist, IL-6, tumor necrosis factor (TNF)-α, transforming growth factor-ß, high sensitivity C-Reactive protein, and fibrinogen, measured at baseline. At baseline, 642 subjects had history of AF, but only 44 had AF in ECG recording. During a mean follow-up of 3.7 years, 108 subjects developed new-onset AF. There was no significant association between inflammatory biomarkers and past history of AF. After adjustment for demographic characteristics, comorbid conditions, laboratory values, echocardiographic variables, and medication use, plasma IL-6 level was significantly associated with presence of AF at baseline (Odds ratio [OR], 1.61; 95% confidence interval [CI], 1.21 to 2.14; P = 0.001) and new-onset AF (OR, 1.25; 95% CI, 1.02 to 1.53; P = 0.03). To summarize, plasma IL-6 level is an independent and consistent predictor of AF in patients with CKD.

ABSTRACT

BACKGROUND: Prevailing recommendations call for restricting intake of dietary cholesterol and eggs for those at risk of heart disease, despite accumulating evidence challenging this association. Our prior studies showed no short-term adverse effects of daily egg intake on cardiac risk factors in at-risk adults. OBJECTIVE: We conducted this study to determine effects of daily egg consumption in adults with established coronary artery disease (CAD). METHODS: Randomized, controlled, single-blind, crossover trial of 32 adults (mean age, 67 years; 6 women, 26 men) with CAD assigned to 1 of 6 possible sequence permutations of 3 different treatments (breakfast with 2 eggs, breakfast with ½ cup Egg Beaters, ConAgra Foods, St. Louis, MO, or a high-carbohydrate breakfast part of an ad libitum diet) for 6 weeks, with 4-week washout periods. The primary outcome measure was endothelial function measured as flow-mediated dilatation. RESULTS: Compared with the control breakfast (ie, high-carbohydrate breakfast), daily consumption of eggs showed no adverse effects on flow-mediated dilatation (7.2% ± 2.9% vs 7.5% ± 2.9%, P = .33), lipids (total cholesterol: 158.3 ± 28.6 mg/dL vs 156.2 ± 27.4 mg/dL, P = .49), blood pressure (systolic blood pressure: 132.8 ± 14.1 mm Hg or vs 135.5 ± 14.9 mm Hg, P = .52; diastolic blood pressure: 77.2 ± 6.1 mm Hg vs 76.7 ± 6.9 mm Hg, P = .86), or body weight (90.8 ± 17.5 kg vs 91.8 ± 17.1 kg, P = .92). No outcomes differed (P > .05) between eggs and Egg Beaters. CONCLUSIONS: We found no evidence of adverse effects of daily egg ingestion on any cardiac risk factors in adults with CAD over a span of 6 weeks.

ABSTRACT

Worsening renal function (WRF) during the treatment of acute decompensated heart failure (ADHF) occurs in up to a third of patients and is associated with worse survival. Venous congestion is increasingly being recognized as a key player associated with WRF in ADHF. Understanding the hemodynamic effects of venous congestion and the interplay between venous congestion and other pathophysiological factors such as raised abdominal pressure, endothelial cell activation, anemia/ iron deficiency, sympathetic overactivity, and stimulation of the renin-angiotensin-aldosterone system will help in devising effective management strategies. Early recognition of venous congestion through novel techniques such as bioimpedance measurements and remote monitoring of volume status combined with customized diuretic regimens may prevent venous congestion and perhaps avoid significant WRF.

ABSTRACT

Leuprolide (Lupron) is a synthetic analog of naturally occurring gonadotropin-releasing hormone (GnRH). Leuprolide is used as a hormonal antagonist in the treatment of advanced prostatic cancer, and as hormonal therapy in the treatment of endometriosis. Off-label, it is also used in premenopausal or perimenopausal women with hormone-responsive breast cancer for the purpose of ovarian ablation. Ever since its FDA approval in 1985, many adverse reactions have been reported in association with leuprolide ranging from local skin irritation to severe anaphylactoid reactions. In this case report, we present a case of hypersensitivity vasculitis (serum sickness) in a patient who received leuprolide for his prostate cancer. Serum sickness has never been reported as a side-effect of leuprolide. Our case is the first case of serum sickness associated with leuprolide. We emphasize that physicians using leuprolide should be wary of signs and symptoms of hypersensitivity vasculitis or serum sickness.

ABSTRACT

In this report we present a case of erlotinib-induced trichomegaly in a male patient who received erlotinib for his pancreatic cancer. Trichomegaly as a side effect of epidermal growth factor receptor (EGFR) inhibitor therapy is uncommon in male patients. Also, it has not been reported previously in a patient with pancreatic cancer. Previous reported cases all involved female lung cancer patients. We emphasize the importance of recognizing the side effects of EGFR inhibitor therapy and its implications on the prognosis of the cancer treated.

ABSTRACT

We present a case of distal renal tubular acidosis and acute renal insufficiency in a patient with Waldenström's macroglobulinemia. Distal renal tubular acidosis has been described in hypergammaglobulinemia, but not in patients with Waldenström's macroglobulinemia. To our knowledge, this is the first report to describe a possible association between distal renal tubular acidosis and Waldenström's macroglobulinemia. Our case also emphasizes the importance of prompt recognition of distal renal tubular acidosis in patients with Waldenström's macroglobulinemia because of its metabolic disturbances and potentially life threatening complications.
