BACKGROUND: Over the last several years significant rises in the use of implanted cardioverter-defibrillators (ICD) have also resulted in a number of associated complications. This number includes lead failure. Sprint Fidelis ICD lead (SF) is regarded as a lead with elevated failure risk. Every center acting in accordance with the guidelines should observe patients more thoroughly especially with recalled leads and run a registry of their follow-up. The aim of the present research was to observe patients with SF leads (types 6948, 6949) from a single implantation center...

Idiopathic pulmonary fibrosis (IPF) is a chronic lethal interstitial lung disease with unknown etiology. Recent studies have indicated that heat-shock protein 27 (HSP27) contributes to the pathogenesis of IPF through the regulation of epithelial-mesenchymal transition (EMT). However, the expression and role of HSP27 in fibroblasts during pulmonary fibrogenesis has not been investigated to date, at least to the best of our knowledge. In this study, we examined the expression of HSP27 in fibrotic lung tissue and fibroblasts from bleomycin (BLM)-challenged mice and human lung fibroblasts treated with transforming growth factor-β (TGF-β)...

This article summarizes some of the recent and clinically relevant advances in chronic pancreatitis. These advances mainly concern the definition of the disease, the etiological diagnosis of idiopathic disease, the correlation between fibrosis degree and pancreatic secretion in the early stages of chronic pancreatitis, the treatment of the disease and of pain, the clinical relevance of pancreatic exocrine insufficiency, and the diagnosis of autoimmune pancreatitis. A new mechanistic definition of chronic pancreatitis has been proposed...

BACKGROUND: Focused cardiac ultrasound (FoCUS) is accurate for determining the presence of a pericardial effusion. Using FoCUS to evaluate for pericardial tamponade, however, is more involved. Many experts teach that tamponade is unlikely if the inferior vena cava (IVC) shows respiratory variation and is not distended. CASE REPORT: A 53-year-old woman presented to the emergency department (ED) with severe orthostatic hypotension, exertional dyspnea, and hypoxia...

Peripartum cardiomyopathy (PPCM) is a rare disorder of unknown etiology and pathogenesis. The most important tool for diagnostic confirmation is transthoracic echocardiography. The recommended management of PPCM in pregnancy is summarized by the European Society of Cardiology Heart Failure Guidelines. Few data exist on the treatment of patients with fulminant PPCM and the need for extracorporeal membrane oxygenation (ECMO) in this context. We report on a young multiparous woman with cardiogenic shock caused by severe PPCM who was successfully, but atypically, supported with veno-venous ECMO as a bridge to recovery immediately after the birth of her third child...

Abdominal pain is a challenging presentation in children. Examination findings and etiology vary greatly, spanning a vast spectrum from flatulence to frank peritonitis with septic shock. Here, we discuss a 10-year-old boy with 24 hours of progressively worsening lower abdominal pain, nausea, and subjective fevers. History and physical examination findings were consistent with appendicitis. However, physicians were surprised when the single-view abdominal radiograph showed an unanticipated, somewhat perplexing discovery...

Dengue virus infection affects the heart structurally and functionally. Clinical manifestations of cardiac complications secondary to dengue virus infection vary from self-limiting arrhythmias to severe myocardial infarction, leading to hypotension, pulmonary edema, and cardiogenic shock. However, we report a case of dengue hemorrhagic fever (DHF) complicated by a complete heart block. A female with DHF due to dengue virus serotype 2, presented to the emergency department with fever, headache, rash, and fatigue followed by an episode of syncope...

Salmonella species are facultative intracellular pathogens that most frequently cause self-limiting gastrointestinal disease, often acquired through the ingestion of contaminated food. We report the case of a 33-year-old otherwise healthy, not overtly immunosuppressed, man who was transferred to our facility with the chief complaint of respiratory failure and septic shock. Computed tomography of the chest revealed multifocal pneumonia in both lungs. A bronchial alveolar lavage was performed in the right middle lobe and cultures predominantly grew Salmonella enterica serovar Enteritidis...

: Export of macromolecules via extracellular membrane-derived vesicles (MVs) plays an important role in the biology of Gram-negative bacteria. Gram-positive bacteria have also recently been reported to produce MVs; however, the composition and mechanisms governing vesiculogenesis in Gram-positive bacteria remain undefined. Here, we describe MV production in the Gram-positive human pathogen group A streptococcus (GAS), the etiological agent of necrotizing fasciitis and streptococcal toxic shock syndrome...

The incidence of syphilis has historically been cyclical in nature, often in relation to the rise and fall of public health initiatives directed toward eradication along with social attitudes toward sexual practices. The incidence of syphilis has increased by 15% in the last 6 years in the United States, with similar increases worldwide. Herein, we present an atypical case of syphilis presenting with severe septic shock and multiple anogenital lesions in an immunocompetent host. A 22-year-old male with no significant past medical history presented with fevers, chills, sore throat, diaphoresis, and diarrhea...

BACKGROUND: Primary prophylactic implantable cardioverter defibrillator (ICD) therapy is indicated for patients with reduced left ventricular ejection fraction (LVEF). We aimed to determine if preoperative clinical risk profiling can predict long-term benefit, and if clinical risk scores can be applied and improved in a patient cohort outside the clinical trial setting. METHODS: Using registry data, 789 patients with reduced LVEF who received ICDs for primary prevention during 2006-2011 were identified (age 64 ± 11 years, 82% men, 63% ischemic etiology, 52% cardiac resynchronization therapy with defibrillator)...

Pancreatolithiasis, or pancreatic calculi (PC), is a sequel of chronic pancreatitis (CP) and may occur in the main ducts, side branches or parenchyma. Calculi are the end result, irrespective of the etiology of CP. PC contains an inner nidus surrounded by successive layers of calcium carbonate. These calculi obstruct the pancreatic ducts and produce ductal hypertension, which leads to pain, the cardinal feature of CP. Both endoscopic therapy and surgery aim to clear these calculi and decrease ductal hypertension...

BACKGROUND: Early determination of the acute etiology of cardiac arrest could help guide resuscitation or post-resuscitation care. In experimental studies, quantitative measures of the ventricular fibrillation waveform distinguish ischemic from non-ischemic etiology. METHODS: We investigated whether waveform measures distinguished arrest etiology among adults treated by EMS for out-of-hospital ventricular fibrillation between January 1, 2006-December 31, 2014. Etiology was classified using hospital information into three exclusive groups: acute coronary syndrome (ACS) with ST elevation myocardial infarction (STEMI), ACS without ST elevation (non-STEMI), or non-ischemic arrest...

BACKGROUND: Development of infection-associated acute encephalopathy (AE) is precipitated by several factors, including viral agents, age, and genetic polymorphisms. In addition, children with prior underlying neurological disorders can also present with AE. METHOD: We reviewed 55 children with AE who were referred to hospitals participating in the Status Epilepticus Study Group from 1988 to 2013. AE was classified into eight subtypes: acute encephalopathy with biphasic seizures and late reduced diffusion (AESD); hemiconvulsion-hemiplegia syndrome (HH); acute necrotizing encephalopathy; hemorrhagic shock and encephalopathy syndrome (HSES); clinically mild encephalitis/encephalopathy with a reversible splenial lesion; acute encephalitis with refractory, repetitive partial seizures; Reye-like syndrome; and unclassified...

BACKGROUND: Laboratory tasks to delineate anxiety disorder features are used to refine classification and inform our understanding of etiological mechanisms. The present study examines laboratory measures of response inhibition, specifically the inhibition of a pre-potent motor response, in clinical anxiety. Data on associations between anxiety and response inhibition remain inconsistent, perhaps because of dissociable effects of clinical anxiety and experimentally manipulated state anxiety...

Several recent gene expression studies on schizophrenia, including one using monozygotic twins discordant for the disease, have reported the upregulation of adrenomedullin (ADM), which was initially identified as a vasodilator hormone. It has been hypothesized that upregulation of ADM may be a susceptibility factor for schizophrenia, although the exact role of ADM in the central nervous system remains unclear. In this study, we used a microarray analysis to investigate the changes in global gene expression induced by the administration of exogenous ADM in SK-N-SH cells, which allowed us to evaluate the effects of elevated ADM on the central nervous system...

The World Health Organization (WHO) has coined the term expanded dengue to describe cases which do not fall into either dengue shock syndrome or dengue hemorrhagic fever. This has incorporated several atypical findings of dengue. Dengue virus has not been enlisted as a common etiological agent in several conditions like encephalitis, Guillain Barre syndrome. Moreover it is a great mimic of co-existing epidemics like Malaria, Chikungunya and Zika virus disease, which are also mosquito-borne diseases. The atypical manifestations noted in dengue can be mutisystemic and multifacetal...
