BACKGROUND: Out-of-hospital emergency care is at an early stage of development in Armenia, with the current emergency medical services (EMS) system having emergency physicians (EPs) work on ambulances along with nurses. While efforts are underway by the Ministry of Health and other organizations to reform the EMS system, little data exists on the status of pediatric emergency care (PEC) in the country. We designed this study to evaluate the knowledge and attitudes of out-of-hospital emergency physicians in pediatric rapid assessment and resuscitation, and identify areas for PEC improvement.
METHODS: We distributed an anonymous, self-administered Knowledge and Attitudes survey to a ...

POG In Press
Ovarian hyperstimulation syndrome (OHSS) is a relatively common complication in infertile patients treated with exogenous gonadotropins. Ovarian hyperstimulation in spontaneous pregnancies is a rare but possible. The pathogenesis of spontaneous OHSS is not well known. Risk factors for OHSS are young age, polycystic ovaries, low body mass index, high gonadotropin dose, increased estradiol and human chorionic gonadotropin levels, multiple pregnancy, OHSS history, molar pregnancy and hypothyroidism. In this report we present a case of severe spontaneous OHSS with a brief summary of the literature. She was hospitalized and treated in the clinic with the diagnosis of severe OHSS accompanying spontaneous ...
Opinions And Expectations Of Nursing Home Administrators, 2014 Western Michigan University
Opinions And Expectations Of Nursing Home Administrators, Jordan I. Kosberg
The Journal of Sociology & Social Welfare
From a comparative analysis of 214 nursing homes in the Chicago area, it was found that the nursing home field is composed of institutions with great variations in treatment resources available to the residents (Kosberg and Tobin, 1972). While the determination of organizational correlates to the extent of treatment resources was the major objective of the study, an exploration of the attitudes of a sample of nursing home administrators was undertaken in an effort to learn of possible relationships between attitudes and the characteristics of facilities.
There is a commonly-held assumption that not only the academic background of an administrator ...
Neonatal Nmda Receptor Blockade Disrupts Spike Timing And Glutamatergic Synapses In Fast Spiking Interneurons In A Nmda Receptor Hypofunction Model Of Schizophrenia, 2014 Himmelfarb Health Sciences Library, The George Washington University
Neonatal Nmda Receptor Blockade Disrupts Spike Timing And Glutamatergic Synapses In Fast Spiking Interneurons In A Nmda Receptor Hypofunction Model Of Schizophrenia, Kevin S. Jones, Joshua G. Corbin, Molly M. Huntsman
Pediatrics Faculty Publications
The dysfunction of parvalbumin-positive, fast-spiking interneurons (FSI) is considered a primary contributor to the pathophysiology of schizophrenia (SZ), but deficits in FSI physiology have not been explicitly characterized. We show for the first time, that a widely-employed model of schizophrenia minimizes first spike latency and increases GluN2B-mediated current in neocortical FSIs. The reduction in FSI first-spike latency coincides with reduced expression of the Kv1.1 potassium channel subunit which provides a biophysical explanation for the abnormal spiking behavior. Similarly, the increase in NMDA current coincides with enhanced expression of the GluN2B NMDA receptor subunit, specifically in FSIs. In this study ...

Sebire, Gordan Vujanic, Elizabeth Perlman, James R. Anderson, Paul Grundy, Jeffrey S. Dome, Kathy Pritchard-Jones
Pediatrics Faculty Publications
The presence of diffuse anaplasia in Wilms tumours (DAWT) is associated with TP53 mutations and poor outcome. As patients receive intensified treatment, we sought to identify whetherTP53 mutational status confers additional prognostic information.
Patients and Methods
We studied 40 patients with DAWT with anaplasia in the tissue from which DNA was extracted and analysed for TP53 mutations and 17p loss. The majority of cases were profiled by copy number (n = 32) and gene expression (n = 36) arrays. TP53 mutational status was correlated with patient event-free and overall survival, genomic copy number instability and gene expression profiling.

Role Of Sirt1 In Vascular Complications Of Diabetes, 2014 Western University
Role Of Sirt1 In Vascular Complications Of Diabetes, Rokhsana Mortuza
University of Western Ontario - Electronic Thesis and Dissertation Repository
Chronic diabetic complications are significant causes of morbidity. In diabetes, as the cellular changes are similar to aging, we investigated the role of sirtuins (SIRTs) in chronic diabetic complications.
We examined glucose and aging-induced changes in the endothelial cells (ECs), the primary targets of chronic diabetic complications. ECs in high glucose showed evidences of early senescence, being more pronounced in microvascular ECs in association with decreased SIRT1 and FOXO1-dependent reduction in antioxidant gene expressions. A regulatory relationship of deacetylator SIRT1 and histone acetylator p300 was identified. Renal and retinal tissues of diabetic animals showed similar results.
Having established such changes ...

William H. Velander Publications
Noncompressible truncal hemorrhage and brain injury currently account for most early mortality of warfighters on the battlefield. There is no effective treatment for noncompressible truncal hemorrhage, other than rapid evacuation to a surgical facility. The availability of an effective field treatment for noncompressible truncal hemorrhage could increase the number of warfighters salvaged from this frequently-lethal scenario. Our intent was to develop a porcine model of noncompressible truncal hemorrhage with a ,50% one-hour mortality so that we could develop new treatments for this difficult problem. Normovolemic normothermic domestic swine (barrows, 3 months old, 34–36 kg) underwent one of three injury ...
Odontogenic Keratocyst Mandible An Interesting Case Report And Literature Review, 2014 SelectedWorks
Odontogenic Keratocyst Mandible An Interesting Case Report And Literature Review, Balasubramanian Thiagarajan, Geetha Ramamoorthy
The term odontogenic keratocyst was first described by Philipsen in 1956. This cyst actually arises from the cell rests of dental lamina. It can occur anywhere in the jaw but is commonly seen in the posterior part of the mandible. Since the clinical features and radiological appearance are not characteristic this condition is commonly misdiagnosed. This is more so when the lesion is related to the nonvital tooth. Odontogenic keratocyst has been rechristened as keratocystic odontogenic tumor by WHO working group in 2005. This was necessitated to differentiate this lesion from its orthokeratinizing variant which is currently considered as odontogenic ...
Subperiosteal Hematoma Of Orbit An Interesting Case Report And Review Of Literature, Balasubramanian Thiagarajan
Subperiosteal Hematoma orbit is an uncommon disorder which may occur following injury to orbit. Of course there are other causes that cause this condition as well. This condition has been reported in young adults. This case report discusses a patient who developed subperiosteal hematoma following trivial injury to orbit. Since this condition had occurred following trivial injury to orbit diagnosis was not made pre operatively. It was discovered only on the table. A high index of suspicion and an accurate history is necessary to identify this condition. This case is being reported not only for its rarity but also to ...

Perampanel Inhibition Of Ampa Receptor Currents In Cultured Hippocampal Neurons, Chao-Yin Chen, Lucas Matt, Johannes Wilhelm Hell, Michael A. Rogawski
Michael A. Rogawski
Perampanel is an aryl substituted 2-pyridone AMPA receptor antagonist that was recently approved as a treatment for epilepsy. The drug potently inhibits AMPA receptor responses but the mode of block has not been characterized. Here the action of perampanel on AMPA receptors was investigated by whole-cell voltage-clamp recording in cultured rat hippocampal neurons. Perampanel caused a slow (τ~1 s at 3 µM), concentration-dependent inhibition of AMPA receptor currents evoked by AMPA and kainate. The rates of block and unblock of AMPA receptor currents were 1.5×105 M−1 s−1 and 0.58 s−1, respectively. Perampanel did ...

Integrated Approach For Accurate Localization Of Optic Disc And Macula, Vaanathi Sundaresan, Keerthi Ram, Niranjan Joshi, Mohanasankar Sivaprakasam, Rashmin Gandhi
Ophthalmic Medical Image Analysis
The location of three main anatomical structures in the retina namely the optic disc, the vascular arch, and the macula is significant for the analysis of retinal images. Presented here is a novel method that uses an integrated approach to automatically localize the optic disc and the macula with very high accuracy even in the presence of confounders such as lens artifacts, glare, bright pathologies and acquisition variations such as non-uniform illumination, blur and poor contrast. Evaluated on a collective set of 579 diverse pathological images from various publicly available datasets, our method achieves sensitivity > 99% and normalized localization error < 5% for optic disc and macula localization.
