Pheochromocytoma has been called 'the great mimic', capable of presenting itself as many other medical conditions. We present a 58-year-old woman admitted with recurrent episodes of nausea and vomiting and high blood pressure. Elevated cardiac biomarkers and diffuse ST-T abnormalities on electrocardiography suggested myocardial injury. However the biochemical and electrocardiography abnormalities normalized in a few hours. The next day the combination of fever, mental disorientation and confusion associated with elevated levels of C-reactive protein and leukocytosis suggested infection of central neural system...

Infective endocarditis (IE) is a serious infectious condition with high morbidity and mortality in patients with end-stage renal disease (ESRD). It has been particularly associated with recurrent bacteremia due to vascular access via lumen catheters. The most common pathogen is Staphylococcus (S.) aureus, and most affected valve is mitral valve, which frequently calcified. Two patients with ESRD who received hemodialysis treatment via tunneled catheters, aged 56 and 88 years, were admitted with fever and high troponin level...

BACKGROUND: Respiratory infection has been associated with an increased short term risk of myocardial infarction (MI). However, previous studies have predominantly been conducted without angiographic confirmation of MI. The possibility can therefore not be excluded that raised troponin levels or electrocardiogram abnormalities that may be seen with respiratory infections are due to non-ischaemic causes. AIMS: To investigate the association between respiratory infection and angiographically confirmed MI...

Intracardiac or intrapulmonary dislodgement of dialysis catheter or guidewire coating is extremely rare. When present, it can be potentially lethal as it may get complicated by arrhythmias, myocardial or pulmonary artery rupture, valvular perforation, pulmonary thromboembolism, infarction, and infective endocarditis. Percutaneous removal should be attempted as an initial measure and is usually effective in most of the cases. We report 2 such cases, where in first patient it was the hemodialysis catheter which broke, with a large part migrating into the heart, while in second patient, it was the hydrophilic coating of the guidewire that migrated into the pulmonary arteries...

The production of nitric oxide (NO) is a key defense mechanism against intracellular pathogens but it must be tightly controlled in order to avoid excessive detrimental oxidative stress. In this study we described a novel mechanism through which interleukin (IL)-6 mediates the regulation of NO release induced in response to Trypanosoma cruzi infection. Using a murine model of Chagas disease, we found that, in contrast to C57BL/6 wild type (WT) mice, IL-6-deficient (IL6KO) mice exhibited a dramatic increase in plasma NO levels concomitant with a significantly higher amount of circulating IL-1β and inflammatory monocytes...

OBJECTIVE: Vasoactive cardiovascular hormones such as the N-terminal prohormone of brain natriuretic peptide (NT-proBNP) are produced upon ventricular stretch and play a central role in neurohumoral pathways of the heart regulating cardiovascular remodeling and volume homeostasis. The impact of HIV infection on these neurohumoral pathways of the heart and its potential reversibility by combinations of antiretroviral therapies remain unclear. METHODS: We assessed serum levels of NT-proBNP in 219 antiretroviral therapy-naïve HIV-infected patients with a normal cardiac and renal status at treatment initiation and after attainment of viremic control...

Thomas Butler
Within 24 hours after antibiotic treatment of the spirochetal infections syphilis, Lyme disease, leptospirosis, and relapsing fever (RF), patients experience shaking chills, a rise in temperature, and intensification of skin rashes known as the Jarisch-Herxheimer reaction (JHR) with symptoms resolving a few hours later. Case reports indicate that the JHR can also include uterine contractions in pregnancy, worsening liver and renal function, acute respiratory distress syndrome, myocardial injury, hypotension, meningitis, alterations in consciousness, seizures, and strokes...

BACKGROUND: PCI has been done traditionally through transfemoral route. But now transradial and transbrachial routes are also coming up in practice. We compared transradial versus transfemoral routes for ease of operability, time for procedure, complications, and failure rates through a prospective study. METHODS: Four hundred Patients admitted in department of cardiology for percutaneous interventions were enrolled in the study. 200 patients were assigned to each group randomly...

Proton Pump Inhibitors are among the most common drugs taken. The indication is for treatment of heartburn, reflux disease, prophylaxis and treatment of peptic ulcers, in combination with NSAIDs and steroids as well as H. pylori-eradication. PPI's are widely used, even with non-specific symptoms. This certainly has to do with good tolerability and a previously considered low side effect profile. At the moment, there is growing evidence that the long-term intake of PPI's may not be as safe as assumed. In addition to interactions with some drugs, including platelet aggregation inhibitors, recent studies have shown an increased risk of myocardial infarction, interstitial nephritis, chronic renal injury, infections, vitamin deficiencies and electrolyte shifts as well developing dementia...

BACKGROUND: There is growing evidence of an interaction between HIV-infection, anti-retroviral therapy (ART) and cardiovascular diseases (CVD). Epidemiological studies in Europe and North America have been observing a shift towards an increased incidence of coronary heart disease and acute myocardial infarctions in HIV-infected populations compared to the general population even after adjusting for traditional cardiovascular risk factors. Despite South Africa (and sub-Saharan Africa, SSA) being regarded as the epicentre of the global HIV epidemic, very little is known about the prevalence of cardiovascular risk factors and precursors of vascular disease in HIV-infected populations in this region...

BACKGROUND: With increasing public reporting of outcomes and bundled payments, hospitals and providers are scrutinized for morbidity and mortality. The impact of patient transfer before colorectal surgery has not been well characterized in a risk-adjusted fashion. OBJECTIVE: We hypothesized that hospital-to-hospital transfer would independently predict morbidity and mortality beyond traditional predictor variables. DESIGN: We constructed a retrospective cohort of 158,446 patients who underwent colorectal surgery using the 2009-2013 American College of Surgeons National Surgical Quality Improvement Program database...

BACKGROUND: Despite extensive research regarding risk factors for adverse events after total joint arthroplasty (TJA), there are few publications describing the timing at which such adverse events occur. QUESTIONS/PURPOSES: (1) On which postoperative day do certain adverse events occur? (2) What adverse events occur earlier after TKA than after THA? (3) For each adverse event, what proportion occurred after hospital discharge? METHODS: We screened the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) to identify all patients undergoing primary THA and primary TKA between 2005 and 2013, resulting in a study population of 124,657 patients evaluated as part of this retrospective database analysis...

Importance: The Second Universal Definition of Myocardial Infarction (MI) divides MIs into different types. Type 1 MIs result spontaneously from instability of atherosclerotic plaque, whereas type 2 MIs occur in the setting of a mismatch between oxygen demand and supply, as with severe hypotension. Type 2 MIs are uncommon in the general population, but their frequency in human immunodeficiency virus (HIV)-infected individuals is unknown. Objectives: To characterize MIs, including type; identify causes of type 2 MIs; and compare demographic and clinical characteristics among HIV-infected individuals with type 1 vs type 2 MIs...

INTRODUCTION: Abdominal based breast reconstruction exists in a continuum from pedicled transverse rectus abdominis myocutaneous (TRAM) flap to deep inferior epigastric perforator (DIEP) free flap. DIEP flap has the advantage of complete rectus abdominis sparing during harvest, thus decreasing donor site morbidity. Aim of this study is to determine whether the surgical advantages of the DIEP flap impact postoperative outcomes versus the free TRAM flap (fTRAM). METHODS: We reviewed the Nationwide Inpatient Sample database (2010-2011) for all cases of DIEP and fTRAM breast reconstruction...

Chao Wang, Chunsheng Dong, Sidong Xiong
Viral myocarditis is the inflammation caused by myocardial virus infection, and the coxsackievirus group B3 virus (CVB3) is the most common pathogen. An efficient therapeutic agent against viral myocarditis is currently unavailable. IL-33, a new member of the IL-1 cytokine superfamily, exhibits potential immunotherapeutic effect against inflammatory and autoimmune diseases. However, the functional role of IL-33 in viral myocarditis has not been investigated. To examine the therapeutic role of IL-33 in viral myocarditis, an IL-33 overexpression plasmid (pDisplay-IL-33) and IL-33 knockdown plasmid (pLL3...

BACKGROUND: Robotic retropubic prostatectomy (RRP) has become one of the most commonly performed robotic procedures in the United States. Ventral hernia (VH) has been increasingly recognized as an important complication after laparoscopic procedures, in general. However, data related to VH after robotic procedures is relatively scarce, especially after RRP. With increasing popularity of RRP, the purpose of this study was to look at the incidence of VH and outcomes of ventral hernia repair (VHR) after RRP...
