A case of ascending aortic dissection mimicking acute myocardial infarction and complicated with pericardial tamponade

Acute aortic dissection (AD) is the most common life-threatening disorder affecting the aorta with an incidence that ranges between 5 to 30 cases per million people per year. The symptoms of aortic dissection may be variable and can mimic other more common conditions such as myocardial ischemia. We report a case of a 60-year-old male who presented with inferior wall ST-elevation myocardial infarction (MI). Emergent coronary angiography revealed an ascending aortic dissection with normal coronary arteries. In addition, his aortic dissection was complicated with pericardial tamponade. The patient was managed with an immediate surgical repair, after that he had an uncomplicated postoperative course and was discharged in a stable condition. This case report illustrates the importance of having a high index of suspicion for AD in cases of chest pain. If AD is suspected in a patient with acute coronary syndrome (ACS), confirming the diagnosis with the appropriate imaging studies should be done as quickly as possible, as misdiagnosis with ACS may lead to the inappropriate administration of thrombolytic or anticoagulant agents resulting in catastrophic outcomes.

Skin rash, eosinophilia, and renal impairment in a patient recently started on allopurinol

Allopurinol is a hypoxanthine analog which inhibits xanthine oxidase, it is a widely used medication for the treatment of hyperuricemia and gout. Allopurinol-induced drug-induced rash with eosinophilia and systemic symptoms syndrome is an infrequent, life-threatening adverse reaction of allopurinol therapy that is remarkable for the higher mortality rate with the use of allopurinol than with the use of another agent. We present a case of a 62-year-old male with a history of chronic kidney disease stage 3, hypertension and gout who developed skin rash, eosinophilia, and renal impairment 2 weeks after he was started on allopurinol therapy for gout. Allopurinol was stopped, and the patient was started on steroids. This case emphasizes that although allopurinol is commonly used the drug for the treatment of gout. However, it can be associated with serious life-threatening complications. Therefore, care should be taken when prescribing allopurinol, and it should be prescribed only for the appropriate indications.

Utility of brain natriuretic peptide assay as a predictor of short term outcomes in patients presenting with syncope to the emergency department

BACKGROUND Syncope is a common condition that accounts for 3% of emergency department (ED) visits and 1-6% of hospital admissions. Current admissions practices result in marginal diagnostic and therapeutic benefit and consume healthcare resources. METHODS This prospective cohort study examined the use of brain natriuretic peptide (BNP) test as a predictor of short term serious outcome in 159 patients who presented to ED with syncope between August 2012 and August 2013 in two tertiary teaching medical centers. RESULTS A total of 41 patients (36%) had serious outcomes within 1 month, 21 of them were in the low BNP group and 20 were in the high BNP group. There was a significantly higher incidence of serious outcomes, myocardial infarction (MI), and life-threatening arrhythmias in the high BNP group. Patients with BNP >250 has an 8.844 fold increase risk of serious outcomes [odds ratio (OR) 8.844, 95% CI: (3.281 to 23.8), P<0.001], a 14.8-fold increase risk of MI [OR =14.8, 95% CI: (1.57 to 139), P=0.011], and a 4.46-fold increase risk life threatening arrhythmia [OR =4.46, 95% CI: (1.15-18.8), P=0.034]. However, there was no statistically significant difference between the two groups in one month mortality, major bleeding, major cardiac procedures or stroke. CONCLUSIONS Our study results further validates the ROSE rule and the utility of BNP in risk stratification of syncope patients. This study showed that measuring BNP and adding ROSE rule to the standard evaluation of syncope can sufficiently predict short-term serious outcomes for patients presenting to ED with syncope.

Aberrant right subclavian artery (arteria lusoria) diagnosed during transradial coronary catheterization

Aberrant right subclavian artery, or arteria lusoria, is the most common aortic arch anomaly. It is an uncommon condition, with an incidence of 0.2–1.7% (1). In this disorder four vessels arise sequentially from the aortic arch: the right common carotid artery, the left common carotid artery, the left subclavian artery and the aberrant right subclavian artery, which crosses upwards and to the right in the posterior mediastinum. It results from a disruption in the complex remodeling of the paired branchial arches, typically of the right dorsal aorta distal to the sixth cervical intersegmental artery (2,3).

Gastrostomy tube migration complicated with acute pancreatitis: Two case reports with review of literature

The percutaneous endoscopic gastrostomy (PEG) tube is an important method of providing enteral nutrition to patients with swallowing disorders and those who need long-term enteral nutritional support. The association between PEG tube migration and acute pancreatitis is rare and was previously described in the literature. To the best of our knowledge, only 11 cases have been reported in the literature. In this article, we are describing two cases of acute pancreatitis secondary to PEG tube balloon migration to the duodenum. These two case reports exemplify that PEG tube migration to the duodenum is not uncommon, and it may lead to disturbance of the biliary flow, obstruction of the ampulla of vater, and acute pancreatitis.

Value of neutrophil to lymphocyte ratio as a predictor of mortality in patients undergoing aortic valve replacement

Background Neutrophil to lymphocyte ratio (NLR) has been studied as a measure of inflammation and as a prognosticating factor in various medical conditions including neoplastic, inflammatory and cardiovascular. The prognostic role of NLR in predicting mortality in patients with aortic stenosis undergoing surgical aortic valve replacement (AVR) has not been studied. The aim of our study is to explore the utility of NLR as a predictor of both, short and long-term mortality, in patients undergoing surgical AVR. Methods Consecutive patients with aortic stenosis admitted for AVR to our institution were evaluated for study inclusion. Of the 335 patients admitted from January 2007 to September 2011, 234 met study inclusion criteria. Patients were divided into two groups depending on their initial preoperative NLR level with a cutoff value of 3. Three-year vital status was accessed with electronic medical records and Social Security Death Index. Survival analysis, stratified by NLR, was used to evaluate the predictive value of preoperative NLR levels. Results Patients with NLR ≥3, when compared to those with NLR <3, had a significantly higher short-term (9.40% vs. 0, P=0.0006), 6-month (19.54% vs. 0.95%, P<0.0001), and 3-year mortality (27.35% vs. 3.78%, P<0.0001). After adjustment for baseline characteristics, co-morbidities, symptomatology, echocardiographic findings, and blood tests, NLR level remained a significant independent predictor of 3-year mortality; Hazard ratios (HRs) increased by a factor of 1.18 (1.05-1.33, P=0.0068) and patients with a NLR ≥3 had 4.77 fold increase in 3-year mortality (1.48-15.32, P=0.0090). Conclusions NLR is an independent predictor of short-term and long-term mortality in patients with aortic stenosis undergoing AVR surgery, especially those with NLR ≥3. We strongly suggest the use of NLR as a tool to risk stratify patients with aortic stenosis undergoing AVR surgery.

An unusual complication of dermatillomania

Dermatillomania or skin picking disorder (sometimes called excoriation disorder, neurotic picking, psychogenic excoriation) is characterized by repetitive skin picking leading to tissue damage. Skin picking may result in significant tissue damage and often leads to medical complications such as localized infections. We present a case of a patient who presented with bacteremia, an extensive workup failed to identify the source of bacteremia. However, skin examination findings helped to identify the source, which was attributed to skin infection secondary to skin picking disorder.

Cardiac troponin and outcome in decompensated heart failure with preserved ejection fraction

BACKGROUND Cardiac troponin (cTn) has been established as an effective prognostic marker in acute heart failure (HF) with predominantly reduced ejection fraction. However, its prognostic value in heart failure with preserved ejection fraction (HFpEF) is unclear. The aim of this study is to describe the prognostic role of troponin I in patients hospitalized for HFpEF decompensation. METHODS We included 363 consecutive patients admitted for HFpEF decompensation that was not associated with acute coronary syndrome (ACS). Patients with troponin level elevation (troponin I level ≥0.04 ng/mL) were compared to patients with normal troponin level. The primary outcome was short-, intermediate-, and long-term all-cause mortality. The secondary outcomes were differences in B-type natriuretic peptide level (BNP), length of stay, and readmission rates between the two groups. RESULTS Nearly half of the patients in the Cohort had troponin level elevation. Troponin level elevation was significantly associated with higher 30-day (4.8% vs. 0.6%, P=0.014), 1-year (12.2% vs. 4.6%, P=0.009), and 2-year mortality (13.8% vs. 5.1%, P=0.005) when compared to a normal troponin level. Troponin level elevation was an independent predictor of mortality after adjusting for clinical and laboratory risk factors seen in HFpEF decompensation. Additionally, BNP level >287 pg/mL, age, and history of atrial fibrillation were identified as statistically significant predictors of mortality. CONCLUSIONS Troponin level elevation, in hospitalized patients with HFpEF decompensation, was associated with higher short-, intermediate-, and long-term mortality.

Warfarin-induced leukocytoclastic vasculitis and proteinuria

Warfarin is typically prescribed for patients with thromboembolic diseases and atrial fibrillation. In addition to the complications of bleeding, allergic skin reaction is one of its rare adverse effects. We herein report a case of a 79 year old male patient with leukocytoclastic vasculitis and proteinuria secondary to warfarin. The warfarin was discontinued and oral prednisone therapy was initiated. The cutaneous lesions and the proteinuria resolved thereafter.

Spontaneous rupture of hepatocellular carcinoma

This is a very interesting case of a 64-year-old female with a history of chronic hepatitis C infection, with abdominal pain and was found to have ruptured hepatocellular carcinoma (HCC). She was managed with the two-stage therapeutic approach first using transarterial embolization to provide adequate hemostasis and then surgical resection with an excellent outcome. This case report exemplifies the importance of early diagnosis and treatment of ruptured HCC.
