Fishing-Injury-Related Flexor Tenosynovitis Of The Hand: A Case Report And Review, Danny A. Young-Afat, Deniz Dayicioglu, John C. Oeltjen, Audene P. Garrison

Surgery Faculty Publications

Hand infections occurring after fishing and other marine-related activities may involve uncommon bacteria that are not susceptible to the conventional or empiric antibiotic therapy used to treat soft tissue infections. Therefore appropriate treatment is often delayed and could lead to severe hand damage. An illustrative case of fishing-related injury leading to complicated tenosynovitis and horseshoe abscess caused by Mycobacterium marinum and its treatment course is outlined. Laceration of the skin during boating is fairly common. Because of the rarity of some of the bacteria, referrals to the appropriate specialist including hand surgeons and infectious disease specialists should occur in early …

Preparing Occupational Therapy And Physiotherapy Students For Work-Related Practice: A Clinical Education Initiative At One Australian University, Kerry Adam, Jenny Strong, Lucinda Chipchase

Internet Journal of Allied Health Sciences and Practice

Purpose: Despite increasing numbers of novice occupational therapists (OTs) and physiotherapists (PTs) entering work-related practice since the early 2000s, clinical learning opportunities are often limited due to legal and insurance issues. In response, clinical educators at The University of Queensland, Australia, developed an industry consultancy service to provide clinical learning for students in this field. Students delivered injury prevention services with supervision from experienced educators. This paper describes the program and an evaluation of student learning.

Master of Medicine in Anaesthesiology

Background: Tourniquet hypertension arising from tourniquet inflation remains of primary concern to the anaesthetist. One drug commonly used to manage tourniquet hypertension is ketamine. Several studies show that ketamine attenuated the blood pressure rise associated with tourniquet inflation. None of the studies carried out examined the effect of ketamine on tourniquet hypertension for a period of more than one hour or an infusion of the same. Objective: To compare the effect of an intravenous infusion of ketamine, versus placebo on tourniquet induced hypertension in patients undergoing upper and lower limb surgery under general anaesthesia Study design: Single blinded Randomized Controlled …

Expression Of Mismatch Repair Proteins In Colorectal Cancer At Aga Khan University Hospital, Nairobi, Charles M. Wahome

Master of Medicine in Anatomic Pathology

Introduction: Microsatellite instability is one of three molecular pathways described in the pathogenesis of colorectal carcinoma. The presence of microsatellite instability in patients with colorectal cancer has implications for prognosis and family counselling. Deficiency in mismatch repair genes leads to microsatellite instability and this can be reliably demonstrated in formalin fixed paraffin embedded tissue by methods, which include immunohistochemistry for the detection of mismatch repair proteins. Local data show a disproportionately large number of younger patients with colorectal cancer compared to that documented in Caucasians. Colorectal cancer in younger ages is often attributed to deficient mismatch repair. The objective of …

Implementation Lessons On The Use Of Innovation In Information Technology In The Developing World, Salim Hasham, Saleem Sayani

Section of Ophthalmology

Information Technology (IT) innovation and its impact on health care is of particular relevance to the developing world, which spends a fraction of what health systems spend in OECD countries. Given the issues of accessibility, affordability and quality health services in the developing world, IT can play an important role by bringing marginalized communities closer to health care systems. Aga Khan University (AKU) and the eHealth Resource Center (eHRC), which are part of Aga Khan Development Network (AKDN), are active in the developing regions of east africa, Central Asia and South East Asia and are currently initiating new changes in …

Self-Assembled Surfactant Cyclic Peptide Nanostructures As Stabilizing Agents, Dindyal Mandal, Rakesh Tiwari, Amir Nasrolahi Shirazi, Donghoon Oh, Guofeng Ye, Antara Banerjee, Arpita Yadav, Keykavous Parang

Pharmacy Faculty Articles and Research

A number of cyclic peptides including [FR](4), [FK](4), [WK](5), [CR](4), [AK](4), and [WR](n) (n = 3-5) containing L-amino acids were produced using solid-phase peptide synthesis. We hypothesized that an optimal balance of hydrophobicity and charge could generate self-assembled nanostructures in aqueous solution by intramolecular and/or intermolecular interactions. Among all the designed peptides, [WR](n) (n = 3-5) generated self-assembled vesicle-like nanostructures at room temperature as shown by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and/or dynamic light scattering (DLS). This class of peptides represents the first report of surfactant-like cyclic peptides that self-assemble into nanostructures. A plausible mechanistic insight into …

Pathology, East Africa

Background: Rapid diagnostic test (RDT) is an important tool for parasite-based malaria diagnosis. High specificity of RDTs to distinguish an active Plasmodium falciparum infection from residual antigens from a previous infection is crucial in endemic areas where residents are repeatedly exposed to malaria. The efficiency of two RDTs based on histidine-rich protein 2 (HRP2) and lactate dehydrogenase (LDH) antigens were studied and compared with two microscopy techniques (Giemsa and acridine orange-stained blood smears) and real-time polymerase chain reaction (PCR) for assessment of initial clearance and detection of recurrent P. falciparum infections after artemisinin-based combination therapy (ACT) in a moderately high …

It is the third most common gynecologic malignancy and estimated to be fifth leading cancer cause of death in women, constituting 23% of all gynecological malignancies. Multi-detector computed tomography (MDCT) appears to offer an excellent modality in diagnosing ovarian cancer based on combination of its availability, meticulous technique, efficacy and familiarity of radiologists and physicians. The aim of this study was to compute sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of 64- slice MDCT in classifying ovarian masses; 95% confidence intervals were reported.MATERIALS AND …

The Use Of Social Media In Undergraduate Curriculum, K Clark-Burg, P Carr, B Hay, K Mcnaught

Nursing Papers and Journal Articles

Social media (SoMe) and mobile technology (MT) have been topics of interest to many educators, health professionals and policy developers over the last decade. This year, two editorials in leading nursing journals have described the potential for SoMe in nursing (Jones & Hayter 2013; Ferguson 2013). A recent Australian journal publication further supports the potential of SoMe and in particular Twitter (Wilson, R, et al. 2013). Increasingly, nurses and other health professionals and the general public are actively utilizing new technology to improve health and enhance practice (Barton, A 2012)]. To-date, there is limited evidence on the use of information …

Nanosecond Pulsed Electric Field (Nspef) Ablation As An Alternative Or Adjunct To Surgery For Treatment Of Cancer, Ru Chen, Xinhua Chen, Stephen J. Beebe

Bioelectrics Publications

Surgery as resection or transplantation remains a fundamental means for cancer treatment and often offers an opportunity for a cure. However, surgery is not always possible because of tumor proximity to blood vessels or ducts or when a patient is not healthy enough to undergo surgery. Application of nanosecond pulsed electric fields (nsPEFs) is a new approach to treat cancer using pulse power technology that was originally designed for military purposes. This novel approach deposits extremely short pulses of high power, low energy electric fields into malignant tissues using electrodes to encompass tumors. Pre-clinical studies show that treatments are effective …

Current Therapeutic Approaches To Equine Protozoal Myeloencephalitis, L. Dirikolu, Jonathan H. Foreman, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

Equine protozoal myeloencephalitis is the most important infectious neurologic disease of horses in the Western Hemisphere. Equine protozoal myeloencephalitis can interfere with a horse's ability to race, work, and perform; untreated, EPM can be lethal. Antemortem diagnosis of EPM is challenging, requiring careful evaluation of the animal's history, clinical signs, and laboratory data, with rigorous exclusion of other causes.

Therapeutic approaches to EPM are evolving. First-generation therapeutic approaches for EPM were based on the classic anti–Toxoplasma gondii pyrimethamine–sulfonamide combinations; treatment is prolonged and can be associated with a considerable relapse rate, which may be associated with the difficulty in …

Atomic Force Microscopy Characterization Of Collagen ‘Nanostraws’ In Human Costal Cartilage, Michael W. Stacey, Diganta Dutta, Anthony Asmar, H. Elsayed-Ali, R. Kelly Jr., A. Beskok

Bioelectrics Publications

Costal cartilage, a type of hyaline cartilage that bridges the bony ribs and sternum, is relatively understudied compared to the load bearing cartilages. Deformities of costal cartilage can result in deformation of the chest wall, where the sternum is largely pushed toward or away from the spine, pectus excavatum and pectus carinatum, respectively, with each condition having significant clinical impact. In the absence of extensive literature describing morphological features of costal cartilage, we characterized a sample from the costal margin immunohistologically and through atomic force microscopy. We had previously observed the presence of collagen ‘nanostraws’ running the length of costal …

Impulsivity Like Traits And Risky Driving Behaviors Among College Students, Matthew R. Pearson, Elaine M. Murphy, Ashley N. Doane

Psychology Faculty Publications

The present study examined the predictive effects of five impulsivity-like traits (Premeditation, Perseverance, Sensation Seeking, Negative Urgency, and Positive Urgency) on driving outcomes (driving errors, driving lapses, driving violations, cell phone driving, traffic citations, and traffic collisions). With a convenience sample of 266 college student drivers, we found that each of the impulsivity-like traits was related to multiple risky driving outcomes. Positive Urgency (tendency to act impulsively when experiencing negative affect) was the most robust predictor of risky driving outcomes. Positive Urgency is a relatively newly conceptualized impulsivity-like trait that was not examined in the driving literature previously, suggesting a …

Fine Tuning A Well-Oiled Machine: Influence Of Nk1.1 And Nkg2d On Nkt Cell Development And Function, Sunil K. Joshi, Mark L. Lang

Bioelectrics Publications

Natural killer T cells (NKT) represent a group of CD1d-restricted T-lineage cells that provide a functional interface between innate and adaptive immune responses in infectious disease, cancer, allergy and autoimmunity. There have been remarkable advances in understanding the molecular events that underpin NKT development in the thymus and in the complex array of functions in the periphery. Most functional studies have focused on activation of T cell antigen receptors expressed by NKT cells and their responses to CD1d presentation of glycolipid and related antigens. Receiving less attention has been several molecules that are hallmarks of Natural Killer (NK) cells, but …

Systems Biology Of The Functional And Dysfunctional Endothelium, Jennifer Frueh, Nataly Maimari, Takayuki Homma, Sandra M. Bovens, Ryan M. Pedrigi, Leila Towhidi, Rob Krams

Department of Mechanical and Materials Engineering: Faculty Publications

This review provides an overview of the effect of blood flow on endothelial cell (EC) signalling pathways, applying microarray technologies to cultured cells, and in vivo studies of normal and atherosclerotic animals. It is found that in cultured ECs, 5–10% of genes are up- or down-regulated in response to fluid flow, whereas only 3–6% of genes are regulated by varying levels of fluid flow. Of all genes, 90%are regulated by the steady part of fluid flow and 10% by pulsatile components. The associated gene profiles show high variability from experiment to experiment depending on experimental conditions, and importantly, the bioinformatical …

A Virus-Encoded Potassium Ion Channel Is A Structural Protein In The Chlorovirus Paramecium Bursaria Chlorella Virus 1 Virion, Giulia Romani, Adrianna Piotrowski, Stefan Hillmer, James Gurnon, James L. Van Etten, Anna Morani, Gerhard Thiel, Brigitte Hertel

James Van Etten Publications

Most chloroviruses encode small K+ channels, which are functional in electrophysiological assays. The experimental finding that initial steps in viral infection exhibit the same sensitivity to channel inhibitors as the viral K+ channels has led to the hypothesis that the channels are structural proteins located in the internal membrane of the virus particles. This hypothesis was questioned recently because proteomic studies failed to detect the channel protein in virions of the prototype chlorovirus Paramecium bursaria chlorella virus 1 (PBCV-1). Here, we used a mAb raised against the functional K+ channel from chlorovirus MA-1D to search for the viral K+ channel …

Potassium Ion Channels: Could They Have Evolved From Viruses?1[W], Gerhard Thiel, Anna Moroni, Guillaume Blanc, James L. Van Etten

James Van Etten Publications

Cells communicate among themselves by electrical activity. Sophisticated membrane-embedded proteins, called ion channels, catalyze rapid, selective, and regulated ion fluxes across membranes (Hille, 2001). The resulting membrane currents are responsible for neuronal activity and the systemic propagation of electrical signals in animals. The activity of some channels is important for muscle movement in animals or growth in plants; other channels sense the concentration of physiological signals and modulate key processes in all kinds of eukaryotic cells. Among the many diverse ion channels in higher organisms, K+ channels are among the most important. One feature of K+ channels is that they …

Venlafaxine-Induced Orthostatic Hypotension In A Geriatric Patient, Vidyashree Chikkaramanjegowda, Jose De Leon

Psychiatry Faculty Publications

Venlafaxine is not usually associated with risk of orthostatic hypotension. A 65-year-old US Caucasian female taking 225 mg/day of venlafaxine extended-release developed symptomatic orthostatic hypotension. The systolic and diastolic blood pressure dropped by 25 and 18 mm Hg, respectively, from supine position to standing position within 3 minutes. The patient was otherwise healthy and the orthostatic hypotension resolved with venlafaxine discontinuation. This was a probable venlafaxine adverse drug reaction according to the Naranjo scale. This case contributes to the scarce literature that indicates that clinicians need to be aware that occasionally venlafaxine can induce clinically significant orthostatic hypotension, particularly in …
