The Efficacy Of Three Types Of Analgesic Drugs In Reducing Pain In The Rainbow Trout, Oncorhynchus Mykiss, Jessica J. Mettam, Lois J. Oulton, Catherine R. Mccrohan, Lynne U. Sneddon

Veterinary Science and Medicine Collection

Recent research has shown the possibility of pain perception in fish; therefore, the use of analgesia or “painkillers” should be considered for invasive procedures. However, there is relatively little information on the effectiveness of analgesic drugs nor on the appropriate dose for fish. This study assessed the efficacy of three types of drug: an opioid, buprenorphine, a non-steroidal anti-inflammatory drug (NSAID), carprofen and a local anaesthetic, lidocaine. Each drug was tested at three doses on rainbow trout that were noxiously stimulated and the most effective dose was also given to fish experiencing no pain to investigate side-effects. Ventilation rate and …

Habituation And Prepulse Inhibition Of The Acoustic Startle In Rodents, Bridget Valsamis, Susanne Schmid

Anatomy and Cell Biology Publications

The acoustic startle response is a protective response, elicited by a sudden and intense acoustic stimulus. Facial and skeletal muscles are activated within a few milliseconds, leading to a whole body flinch in rodents. Although startle responses are reflexive responses that can be reliably elicited, they are not stereotypic. They can be modulated by emotions such as fear (fear potentiated startle) and joy (joy attenuated startle), by non-associative learning processes such as habituation and sensitization, and by other sensory stimuli through sensory gating processes (prepulse inhibition), turning startle responses into an excellent tool for assessing emotions, learning, and sensory gating. …

The Role Of Surgery In Building Resilience To Blast Attacks, Vivian Mcalister

Data and Test Instruments

Blast attacks are the commonest form of terrorist attack on civilians. Blast often causes injury from industrial accidents. Blast injury is the most common cause of injury and death in modern combat. A recent review of Canadian fatal casualties in Afghanistan found 81% to have been caused by blast, almost four times the number killed by gun shot wounds. Improvised explosive devices (IED) caused 78% of the blasts with another 20% being due to rocket propelled grenades (RPG).1 The purpose of this review is to outline the mechanisms of injury, to define the surgical response and to understand the implications …

B-Cell Lymphoma Of The Brainstem With Central Neurogenic Hyperventilation, S. Ather Enam, Rushna Ali

Section of Neurosurgery

Non-Hodgkin's lymphoma of the brainstem is a rare entity. Central Neurogenic Hyperventilation (CNH), an associated manifestation of this disease, is an even rarer event. We report a case of an immunocompetent individual who presented to us with tachypnea and facial nerve palsy. Neuroimaging showed a Cerebellopontine angle tumour which on histopathology showed feature consistent with a Non-Hodgkin's B-Cell Lymphoma. The patient went on to develop severe respiratory alkalosis with findings consistent with CNH. Chemotherapy with Methotrexate was started and high dose Dexamethasone was added to the regimen a month later. Radiologically, the tumour size decreased by 50% but the patient's …

Department of Surgery Gibbon Society Historical Profiles

Throughout history there have been many discoveries that have changed the world, including Albert Einstein’s theory of relativity, Alexander Graham Bell’s telephone, and Jack Kilby and Robert Noyce’s microchip. There are a few analogous contributions that have been made in medicine: Sir Alexander’s discovery of penicillin, Lister’s principles of antiseptic technique, Salk and Sabin’s vaccines for polio, as well as numerous others. These innovative thinkers all had two factors in common. First, they were pioneers who faced problems that had no solutions at the time and who refused to accept the status quo in the face of great scrutiny and …

Mechanisms Of Resistance To Raf Inhibitors In Melanoma., A E Aplin, Fred M Kaplan, Yongping Shao

Department of Cancer Biology Faculty Papers

The recent RAF inhibitor trial with PLX4032/RG7204 in late-stage mutant B-RAF melanoma patients has been lauded as a success story for personalized cancer therapy since short-term clinical responses were observed in the majority of patients. However, initial responses were followed by subsequent tumor re-growth, and a subset of patients showed intrinsic resistance. Bi-directional translational efforts are now essential to determine the mechanisms underlying acquired/secondary and intrinsic resistance to RAF inhibitors.

Scleroderma Renal Crisis-Like Acute Renal Failure Associated With Mucopolysaccharide Accumulation In Renal Vessels In A Patient With Scleromyxedema., Young H Lee, Joya Sahu, Marie S O'Brien, Vivette D D'Agati, Sergio A. Jimenez

Scleroderma Center Faculty Papers

Scleromyxedema is a systemic disease characterized by lichenoid papules, nodules, and plaques on the skin and often diffuse skin induration resembling the cutaneous involvement of systemic sclerosis. The systemic involvement affects the musculoskeletal, pulmonary, cardiovascular, gastrointestinal, and central nervous systems, and the disorder is commonly associated with a paraproteinemia. Involvement of the kidney is rare and not considered a feature of the disease. Here, we describe an unusual case of scleromyxedema complicated by the development of scleroderma renal crisis-like acute renal failure with a marked intimal deposition of mucin, mucopolysaccharides, and hyaluronic acid in the intrarenal vessels.

Among children aged 0-14 years females suffered twice as many RTA injuries as males (21.3% versus 11.4%), whereas this trend reversed for the age group 15-24 years (41.9% versus 21.7%). One-fifth of injuries were either fractures or concussion. …

Malignant Psoas Abscess Or Pseudomyxoma Extraperitonei, Amber Mehmood, Kiran Ejaz, Turab Ibrahim Pishori

Department of Emergency Medicine

Primary adenocarcinoma of appendix is an uncommon gastrointestinal malignancy. Similarly, Psoas abscess is an entity, which sometimes requires extensive work-up to reach a diagnosis. Combined presentation of these two rare conditions is not only exceptional, but also diagnostically challenging. We present a case of a lady who presented with recurrent UTI secondary to right sided ureteric obstruction, referred right hip joint pain resulting from a Psoas abscess, which eventually turned out to be a consequence of metastatic adenocarcinoma of appendix, causing pseudomyxoma extraperitonei, with simultaneous intraperitoneal deposits.

Respiratory Dyskinesia--An Under-Recognized Side-Effect Of Neuroleptic Medications, Mukesh Mohan Bhimani

Department of Psychiatry

Respiratory dyskinesia is an under-recognized side effect of neuroleptic administration. There are only few studies that have addressed the prevalence of respiratory dyskinesia in patients with tardive dyskinesia. Our case report highlights the need to regularly examine patients on antipsychotics for any evidence of dyskinetic movements including respiratory musculature. Since RD is underrecognized and misdiagnosed, early detection can improve long term prognosis as treatment options are few and usually of only limited effect. A 62-year-old Asian male, retired civil engineer, had more than 20 years history of depressive illness, developed antidepressant induced hypomania, and was given risperidone upto 1 mg …

Load Carriage Distance Run And Pushups Tests: No Body Mass Bias And Occupationally Relevant, Paul M. Vanderburgh, Nicholas S. Mickley, Philip A. Anloague, Kimber Lucius

Health and Sport Science Faculty Publications

Recent research has demonstrated body mass (M) bias in military physical fi tness tests favoring lighter, not just leaner, service members. Mathematical modeling predicts that a distance run carrying a backpack of 30 lbs would eliminate M-bias. The purpose of this study was to empirically test this prediction for the U.S. Army push-ups and 2-mile run tests. Two tests were performed for both events for each of 56 university Reserve Offi cer Training Corps male cadets: with (loaded) and without backpack (unloaded). Results indicated signifi cant M-bias in the unloaded and no M-bias in the loaded condition for both events. …

Likelihood Of Asking For Help In Caregivers Of Women With Substance Use Or Co-Occurring Substance Use And Mental Disorders, Suzanne Brown, David E. Biegel, Elizabeth M. Tracy

Social Work Faculty Publications

Family members are important to the well-being of their relatives with substance use disorders or cooccurring substance use and mental disorders. Many caregivers experience high levels of burden, negatively impacting their capacity to provide support to their ill family member. The Andersen health care utilization model (Andersen & Newman, 1973, 2005) was used to identify the impact of predisposing, enabling, and need factors hypothesized to predict caregivers’ likelihood of asking for help and support with their caregiving role. The sample include 82 women recruited from outpatient or inpatient substance abuse treatment centers and 82 family caregivers nominated by these women. …

Department of Medicine Faculty Papers

The proliferation signal inhibitors (PSIs)-sirolimus, everolimus, and temsirolimus-have been associated with a noninfectious pneumonitis characterized by lymphocytic alveolitis and bronciolitis obliterans with organizing pneumonia (BOOP). This condition usually occurs within the first year. Herein we presented a case of a deceased donor renal transplant with interstitial pneumonitis developing 6 years after a switch from tacrolimus to sirolimus due to chronic graft dysfunction. After the addition of intravenous pentamidine due to the suspicion of Pneumocystis pneumonia, there was marked clinical deterioration requiring intubation. Open lung biopsy revealed sirolimus-induced pulmonary toxicity (BOOP) with the additional finding of a drug-induced phospholipidosis (DIPL) that …
