Losartan Associated Anaphylaxis And Angioneurotic Oedema, Syed Faraz Kazim, Muhammad Shahid

Section of General Surgery

A case of anaphylaxis and angioedema induced by angiotensin II receptor blocker (ARB), losartan is reported. A 37 years old hypertensive female presented to the Emergency Department with swelling over the face especially the lips, urticarial rash all over the body, and dyspnoea within an hour of losartan administration. She did not have any previous history of drug allergies. The patient was managed with epinephrine. Although angioneurotic oedema and anaphylaxis are well documented adverse effects of angiotensin converting enzyme (ACE) inhibitors, very few cases of these adverse reactions with ARBs have been reported in medical literature.

The study aimed at determining the incidence, nature, and extent of childhood injuries in two suburban and rural communities of Pakistan. The findings of the study are based on a cross-sectional survey of 2,292 children aged 1-8 years. Information was sought retrospectively from the primary caregiver on the occurrence of injury that required formal or informal medical consultation during the past three months. The incidence rate of non-fatal injuries that required care outside home for children aged 1-8 years was 19.7 injuries per 100 person (child)-years of exposure [95% confidence interval (CI) 16.41-23.51]: 26.5 injuries per 100 person (child)-years of …

Implementing The 2005 American Heart Association Guidelines, Including Use Of The Impedance Threshold Device, Improves Hospital Discharge Rate After In-Hospital Cardiac Arrest, K Thigpen, Scott Davis, Roberta Basol, Peggy Lange, Sandeep Jain, John Olsen, Bernard Erickson, Timothy Schuchard

Articles

OBJECTIVE:

To determine the impact of the 2005 American Heart Association cardiopulmonary resuscitation (CPR) guidelines, including use of an impedance threshold device (ITD), on survival after in-hospital cardiac arrest.

METHODS:

Two community hospitals that tracked outcomes after in-hospital cardiac arrest pooled and compared their hospital discharge rate before and after implementing the 2005 American Heart Association CPR guidelines (including ITD) in standardized protocols. In CPR we used the proper ventilation rate, allowed full chest-wall recoil, conducted continuous CPR following intubation, and used an ITD. We compared historical control data from a 12-month period at St Cloud Hospital, St Cloud, Minnesota, …

Macrophages Loaded With Gold Nanoshells For Photothermal Ablation Of Glioma: An In Vitro Model, Amani Riad Makkouk

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current median survival of patients with glioblastoma multiforme (GBM), the most common type of glioma, remains at 14.6 months despite multimodal treatments (surgery, radiotherapy and chemotherapy). This research aims to study the feasibility of photothermal ablation of glioma using gold nanoshells that are heated upon laser irradiation at their resonance wavelength. The novelty of our approach lies in improving nanoshell tumor delivery by loading them in macrophages, which are known to be recruited to gliomas via tumor-released chemoattractive agents. Ferumoxides, superparamagnetic iron oxide (SPIO) nanoparticles, are needed as an additional macrophage load in order to visualize macrophage accumulation in …

Phospholemman: A Novel Cardiac Stress Protein., Joseph Y Cheung, Xue-Qian Zhang, Jianliang Song, Erhe Gao, Joseph E Rabinowitz, Tung O Chan, Jufang Wang

Center for Translational Medicine Faculty Papers

Phospholemman (PLM), a member of the FXYD family of regulators of ion transport, is a major sarcolemmal substrate for protein kinases A and C in cardiac and skeletal muscle. In the heart, PLM co-localizes and co-immunoprecipitates with Na(+)-K(+)-ATPase, Na(+)/Ca(2+) exchanger, and L-type Ca(2+) channel. Functionally, when phosphorylated at serine(68), PLM stimulates Na(+)-K(+)-ATPase but inhibits Na(+)/Ca(2+) exchanger in cardiac myocytes. In heterologous expression systems, PLM modulates the gating of cardiac L-type Ca(2+) channel. Therefore, PLM occupies a key modulatory role in intracellular Na(+) and Ca(2+) homeostasis and is intimately involved in regulation of excitation-contraction (EC) coupling. Genetic ablation of PLM results …

The Role Of Unrealistic Optimism In Explaining Preventive Behaviors In High Versus Low Endemic Malaria Settings In Belize, Daniel G. Handysides

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Of all the diseases an individual can encounter in the world, malaria is one of the most destructive. Simple measures like sleeping under a bednet would greatly reduce the burden (Abeku, 2007). When people estimate their risk relative to others, they are most often unrealistically optimistic, which may explain why those at risk often fail to perform behaviors, such as using a bednet that will reduce their risk. However, one study showed that people at high risk for malaria held pessimistic perceptions of their risk for the disease, but the reasons for this finding are unclear (Morrison, Ager, & …

The Relationship Between The Level Of Support Group Participation And Psychosocial Factors In Prostate Cancer Patients Treated With Proton Therapy, Carol A. L. Davis

Loma Linda University Electronic Theses, Dissertations & Projects

Background. The role of support groups for cancer patients is known to be beneficial in helping people adjust to the disease, and cope with the myriad of effects that cancer has on quality of life. Although many people express interest in attending such support groups, few attend regularly. It is unclear what characteristics distinguish those who use such services from those who do not, especially among proton therapy patients.

Objective. To examine demographic and psychosocial characteristics associated with the Brotherhood of the Balloon (BOB) prostate cancer support group membership, a unique treatment-focused group originating at Loma Linda University Medical Center …

This evaluation combines previously collected program statistics with surveys (32) from program volunteers and phone interviews (78) with recipients.

Hip Power Asymmetry In Older Adult Fallers And Non-Fallers, Lauren Grace Mcdonald

Boise State University Theses and Dissertations

The purpose of this study was to determine if a difference exists in hip power asymmetry between community-dwelling older adult fallers and non-fallers. Hypothesis: fallers would be more asymmetrical than non-fallers. Participants: 21 non-fallers (10 females, 11 males) and 18 fallers (14 females, 4 males) over the age of 65 (76.5 ± 6.9yrs). Method: Isokinetic peak torque during flexion, extension, abduction, and adduction at four velocities was recorded as measures of leg power. Asymmetry equaled the percent of power difference between each leg. Data analysis: Differences in age, physical activity, height, weight, and BMI were assessed …

The Perils Of The Imperfect Expectation Of The Perfect Baby., Frank A Chervenak, Laurence B Mccullough, Robert L Brent

Department of Pediatrics Faculty Papers

Advances in modern medicine invite the assumption that medicine can control human biology. There is a perilous logic that leads from expectations of medicine's control over reproductive biology to the expectation of having a perfect baby. This article proposes that obstetricians should take a preventive ethics approach to the care of pregnant women with expectations for a perfect baby. We use Nathaniel Hawthorne's classic short story, "The Birthmark," to illustrate the perils of the logic of control and perfection through science and then identify possible contemporary sources of the expectation of the perfect baby. We propose that the informed consent …

Use Of Orthogonal Or Parallel Plating Techniques To Treat Distal Humerus Fractures., Joshua M. Abzug, Phani K. Dantuluri

Department of Orthopaedic Surgery Faculty Papers

Distal humerus fractures continue to be a complex fracture to treat. This article describes two surgical techniques that can be used to tackle these difficult fractures: Parallel plating and orthogonal plating. Both techniques have yielded excellent outcomes after open reduction and internal fixation; yet each has its own set of unique considerations. However, the key to successful treatment of these difficult fractures regardless of technique remains obtaining anatomic reduction with stable fixation and the implementation of early motion.

Characterization Of Optically Stimulated Luminescent Detectors In Photon & Proton Beams For Use In Anthropomorphic Phantoms, James R. Kerns

Dissertations and Theses (Open Access)

This study investigated characteristics of optically stimulated luminescent detectors (OSLDs) in protons, allowing comparison to thermoluminescent detectors, and to be implemented into the Radiological Physics Center’s (RPC) remote audit quality assurance program for protons, and for remote anthropomorphic phantom irradiations. The OSLDs used were aluminum oxide (Al2O3:C) nanoDots from Landauer, Inc. (Glenwood, Ill.) measuring 10x10x2 mm3. A square, 20(L)x20(W)x0.5(H) cm3 piece of solid water was fabricated with pockets to allow OSLDs and TLDs to be irradiated simultaneously and perpendicular to the beam. Irradiations were performed at 5cm depth in photons, and in the center of a 10 cm SOBP in …

An Implantable Mosfet Dosimeter Modified To Act As A Fiducial Marker, Joseph S. Dick

Dissertations and Theses (Open Access)

In external beam radiation therapy, it is imperative that the prescribed dose is administered to the correct location and in the correct amount. Though several ex vivo methods of quality assurance are currently employed to achieve this goal, verifying that the correct dose is received within the patient in situ is impossible without the capability of measuring dose inside the patient. Recently, a method of measuring dose delivered within the patient has been developed, an implantable MOSFET dosimeter. This dosimeter is implanted within the patient and records the dose received. Since the dosimeter is implanted in the patient, it could …

Effect Of Acute Administration Of Angiopoietin-1 In Experimental Traumatic Spinal Cord Injury: Magnetic Resonance Imaging And Neurobehavioral Studies, Chirag B. Patel

Dissertations and Theses (Open Access)

Spinal cord injury (SCI) is a devastating condition that affects people in the prime of their lives. A myriad of vascular events occur after SCI, each of which contributes to the evolving pathology. The primary trauma causes mechanical damage to blood vessels, resulting in hemorrhage. The blood-spinal cord barrier (BSCB), a neurovascular unit that limits passage of most agents from systemic circulation to the central nervous system, breaks down, resulting in inflammation, scar formation, and other sequelae. Protracted BSCB disruption may exacerbate cellular injury and hinder neurobehavioral recovery in SCI.

In these studies, angiopoietin-1 (Ang1), an agent known to reduce …

Benchmarking And Implementation Of A New Independent Monte Carlo Dose Calculation Quality Assurance Audit To Ol For Clinical Trials, Scott E. Davidson

Dissertations and Theses (Open Access)

Introduction Commercial treatment planning systems employ a variety of dose calculation algorithms to plan and predict the dose distributions a patient receives during external beam radiation therapy. Traditionally, the Radiological Physics Center has relied on measurements to assure that institutions participating in the National Cancer Institute sponsored clinical trials administer radiation in doses that are clinically comparable to those of other participating institutions. To complement the effort of the RPC, an independent dose calculation tool needs to be developed that will enable a generic method to determine patient dose distributions in three dimensions and to perform retrospective analysis of radiation …

Dynamic Chemical Shift Imaging For Image-Guided Thermal Therapy, Brian A. Taylor

Dissertations and Theses (Open Access)

Magnetic resonance temperature imaging (MRTI) is recognized as a noninvasive means to provide temperature imaging for guidance in thermal therapies. The most common method of estimating temperature changes in the body using MR is by measuring the water proton resonant frequency (PRF) shift. Calculation of the complex phase difference (CPD) is the method of choice for measuring the PRF indirectly since it facilitates temperature mapping with high spatiotemporal resolution. Chemical shift imaging (CSI) techniques can provide the PRF directly with high sensitivity to temperature changes while minimizing artifacts commonly seen in CPD techniques. However, CSI techniques are currently limited by …

An Innovative Phase I Trial Design Allowing For The Identification Of Multiple Potential Maximum To Lerated Doses With Combination Therapy Of Targeted Agents, Sarina A. Piha-Paul

Dissertations and Theses (Open Access)

Treatment for cancer often involves combination therapies used both in medical practice and clinical trials. Korn and Simon listed three reasons for the utility of combinations: 1) biochemical synergism, 2) differential susceptibility of tumor cells to different agents, and 3) higher achievable dose intensity by exploiting non-overlapping toxicities to the host. Even if the toxicity profile of each agent of a given combination is known, the toxicity profile of the agents used in combination must be established. Thus, caution is required when designing and evaluating trials with combination therapies. Traditional clinical design is based on the consideration of a single …

Spontaneous Disconnection Of Glaucoma Tube Shunt Extenders., Oseluese Dawodu, Alex V. Levin

Wills Eye Hospital Papers

Glaucoma drainage implants are frequently used in children with severe forms of glaucoma, and tube extenders are sometimes required to compensate for ocular growth or when the intraocular portion of the tube is thought to be too short. We report 2 cases of spontaneous disconnection of a tube extender, occurring 8 months after insertion in one case and 3 years later in the other. In both cases the tube was removed and the patient treated with endoscopic diode laser photocoagulation.
