Background: Central venous catheters (CVCs) are frequently used for monitoring haemodynamic status and rapidly delivering fluid therapy during the peri- and postoperative periods. Indwelling CVCs are typically used 7-14 days postoperatively for additional monitoring and treatment, but patients may develop asymptomatic catheter-related thrombosis, leading to life-threatening pulmonary embolism and death. Early detection helps to avoid such complications. Methods: This prospective observational study investigated the risk factors associated with catheter-related right internal jugular vein thrombosis in patients undergoing chest surgery...

Vedolizumab (VDZ) inhibits α4β7 integrins and is used to target intestinal immune responses in patients with inflammatory bowel disease, which is considered to be relatively safe. Here we report on a fatal complication following VDZ administration. A 64-year-old female patient with ulcerative colitis (UC) refractory to tumor necrosis factor inhibitors was treated with VDZ. One week after the second VDZ infusion, she was admitted to hospital with severe diarrhea and systemic inflammatory response syndrome (SIRS)...

BACKGROUND: Opioid overdose is a major cause of mortality, but injury and fatal outcomes can be prevented by timely administration of the opioid antagonist naloxone. Pre-provision of naloxone to opioid users and family members (take-home naloxone, THN) was first proposed in 1996, and WHO Guidelines were issued in 2014. While widespread in some countries, THN is minimally available or absent elsewhere. This review traces the development of THN over twenty years, from speculative harm reduction proposal to public health strategy...

INTRODUCTION: The main recipients of lithium, people diagnosed with bipolar disorder, show an increased mortality in both natural and unnatural causes of death. Based on international data persons diagnosed with bipolar disorder comprise 2.3-9.6% of all suicidal deaths. In cases of suicide among those suffering from bipolar disorder, 17-53% are due to fatal intoxications. Diagnosing fatal intoxications is often challenging, particularly when the reference information needed to interpret the concentration of a drug is lacking or scarce...

INTRODUCTION: While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including eye injuries and falls. With the presence of explosive fumes or fuels there also exists the possibility of burn injury. METHODS: We searched for cases of fatal and non-fatal major burns with TASER(®) electrical weapon usage where there was a possibility that the weapon ignited the explosion. RESULTS: We confirmed 6 cases of fatal burn injury and 4 cases of major non-fatal burns out of 3...

Primary Evans syndrome (ES) is defined by the concurrent or sequential occurrence of immune thrombocytopenia and autoimmune hemolytic anemia in the absence of an underlying etiology. The syndrome is characterized by a chronic, relapsing, and potentially fatal course requiring long-term immunosuppressive therapy. Treatment of ES is hardly evidence-based. Corticosteroids are the mainstay of therapy. Rituximab has emerged as the most widely used second-line treatment, as it can safely achieve high response rates and postpone splenectomy...

Western equine encephalitis virus (WEEV) naturally cycles between mosquitos and birds or rodents, with a case fatality rate of up to 15% in humans during epizootic outbreaks. There are no medical countermeasures to treat WEEV infection, and accidental aerosol exposure increases the case fatality rate up to 40%. Understanding the pathogenesis of infection is required to develop and assess medical countermeasures. This study describes the clinical and pathological findings of mice infected with WEEV by the aerosol route, and use as a model for WEEV infection in humans...

This paper assesses the effectiveness of child safety seat laws in the United States. Over the past 35 years, these laws have steadily increased mandatory child safety seat restraint ages. We exploit state-year level variation in the age until which children are required to ride in child safety seats to estimate triple difference models using Fatality Analysis Reporting System (FARS) data from 1975 to 2011. Our findings show that increasing the age thresholds is effective in increasing the actual age of children in safety seats...

PURPOSE: H1-antihistamines are commonly used in infants and children for the relief of histamine-mediated symptoms in a variety of conditions. Little is known about their safety profile in these patients. We performed a comparative analysis of the safety profiles of H1-antihistamines using data from the WHO database (VigiBase). METHODS: We selected adverse drug reaction (ADR) reports on H1-antihistamines in children (0-16 years) up to June 2014 from VigiBase. ADRs were codified according to MedDRA terminology...

Biallelic mutations in SLC25A46, encoding a modified solute transporter involved in mitochondrial dynamics, have been identified in a wide range of conditions such as hereditary motor and sensory neuropathy with optic atrophy type VIB (OMIM: *610826) and congenital lethal pontocerebellar hypoplasia (PCH). To date, 18 patients from 13 families have been reported, presenting with the key clinical features of optic atrophy, peripheral neuropathy, and cerebellar atrophy. The course of the disease was highly variable ranging from severe muscular hypotonia at birth and early death to first manifestations in late childhood and survival into the fifties...

BACKGROUND: Ebola Virus Disease (EVD) can be clinically severe and highly fatal, making surveillance efforts for early disease detection of paramount importance. In areas with limited access to laboratory testing, the Integrated Disease Surveillance and Response (IDSR) strategy in the Democratic Republic of Congo (DRC) may be a vital tool in improving outbreak response. METHODS: Using DRC IDSR data from the nation's four EVD outbreak periods from 2007-2014, we assessed trends of Viral Hemorrhagic Fever (VHF) and EVD differential diagnoses reportable through IDSR...

An overdose of γ-hydroxybutyric acid (GHB), a drug of abuse, results in fatality caused by severe respiratory depression. In this study, a semi-mechanistic pharmacokinetic/pharmacodynamic (PK/PD) model was developed to characterize monocarboxylate transporter 1 (MCT1)-mediated transport of GHB, as well as effects of GHB on respiration frequency, for IV doses of 200, 600, and 1500 mg/kg in rats. The proposed PK/PD model for GHB consists of nonlinear metabolism of GHB in the liver, MCT1-mediated renal reabsorption with physiologically relevant concurrent fluid reabsorption, MCT1-mediated uptake into the brain, and direct effects of binding of GHB to GABAB receptors on the PD parameter, respiration frequency...

Clostridium septicum produces a number of diseases in human and farm animals which, in most of the cases, are fatal without clinical intervention. Alpha toxin is an important agent and the unique lethal virulent factor produced by Clostridium septicum. This toxin is haemolytic, highly lethal and necrotizing activities but is being used as an antigen to develop animal vaccines. The aim of this study was to isolate the alpha toxin of Clostridium septicum and produce highly specific antibodies against it. In this work, we have developed a simple and efficient method for alpha toxin purification, based on electroelution that can be used as a time-saving method for purifying proteins...

Spontaneous rupture is one of the most fatal complications of hepatic tumors such as hepatocellular carcinoma. In fact, many studies have shown that the in-hospital and 30-d mortality rates are as high as 25%-100%. Cholangiolocellular carcinoma (CoCC) is a rare primary hepatic tumor, usually small in size, that is thought to originate from the ductules and/or canals of Hering. Here, we present a case of spontaneous rupture of a CoCC that was successfully resected by radical surgery. Although CoCC is a rare primary hepatic tumor, it demonstrates certain specific clinical features, including a better prognosis than for other primary liver cancers, and thus should be distinguished from those other cancers...

Herpes zoster is a common disease caused due to varicella zoster virus (VZV) infection with increasing incidence by age. If the patient has a severe, extended, or treatment-recalcitrant course of herpes zoster, this must be a red flag to search for underlying pathologies. Here, we report about a 64-year-old male patient with diabetes, who came to our emergency department because of general malaise, fever, chills, and a pronounced nuchal and facial swelling on the left side. Based on herpetiform-grouped vesicles and yellowish crusts, an impetiginized facial herpes zoster was diagnosed, and combined antiviral and antibiotic treatment was initiated...

Fatal Candida albicans infections in the mucosal system can occur in association with immune-compromised diseases and dysbacteriosis. Currently, amphotericin B (AmB) is considered to be the most effective antibiotic in the treatment of C. albicans infections, but its clinical application is limited by side effects and poor bioavailability. In order to use AmB in the local treatment of oral C. albicans infections, AmB/MPEG-PCL-g-PEI (monomethoxy poly(ethylene glycol)-poly(epsilon-caprolactone)-graft-polyethylenimine, MPP) micelles were prepared...

Acute pulmonary oedema is a significant cause of morbidity and mortality in pregnant and postpartum women. We present an unusual case of near-fatal acute pulmonary oedema in a pregnant woman, which was attributed to the acute onset of neurogenic pulmonary oedema secondary to epileptic seizure activity. The patient required supportive management in the intensive care setting for a short period and subsequently made complete recovery with regular neurological follow-up arranged for the management of her epilepsy...

Diffuse leptomeningeal glioneuronal tumor, a recent addition to the WHO classification system, typically presents in the pediatric population with signs and symptoms related to elevated intracranial pressure and imaging characteristics that may mimic infectious etiologies. The tumor is usually low-grade and tends to harbor BRAF rearrangement/duplication in up to 75% of cases, BRAF V600E mutation in a smaller subset of cases, and loss of chromosomal arm 1p in approximately 50-60% of cases, with ~20% of those showing loss of both 1p and 19q (codeletion)...

PRBC transfusion remains the mainstay of treatment of anemia in MDS after failure of erythropoiesis stimulating agents. The most common transfusion trigger in transfusion-dependent MDS patients is 80g/L. This level is based only on expert consensus; a randomized controlled trial comparing restrictive against liberal policy is required to evaluate potential impact of transfusion policy on with QoL and survival. Prophylactic antigen matching for RhCE and K must be used in order to reduce the risk of red blood cell (RBC) alloimmunization...
