Background: Our institution has longstanding post-graduate education and training partnership programs in Emergency Medicine (EM) across India. A programmatic challenge has been the integration and uptake of evidence-based medicine and lifelong learning concepts. Formative assessment (FA) is intended to enable learners to monitor learning, identify strengths and weaknesses, and target areas of growth.

Multidose pharmacokinetics and safety of a modified, compounded theophylline product in dogs.

Theophylline is used in canine medicine for the management of chronic bronchitis and bradyarrhythmias, yet no species-validated commercial products are available. This study reports the single-dose and multidose pharmacokinetics and safety of a modified, compounded theophylline (MCT) product readily available from a well-established, USP-compliant compounding pharmacy, which may be a suitable and reliable source for theophylline for dogs. Eleven dogs underwent serial plasma theophylline measurement following 10 mg/kg MCT PO.

Biomechanical properties of canine staphylectomies closed with barbed or smooth suture.

Objective: To compare the duration of closure and biomechanical properties of staphylectomies closed with absorbable bidirectional barbed suture or smooth monofilament suture in a simple continuous or interrupted pattern STUDY DESIGN: Ex vivo study SAMPLE POPULATION: Soft palates (n = 60) harvested from mesaticephalic canine cadavers METHODS: One centimeter of tissue was excised from the caudal border of each soft palate, and the oral and nasopharyngeal mucosal surfaces were apposed with 2-0 bidirectional Quill Monoderm knotless closure device barbed suture (Q), 3-0 Monocryl in a simple continuous (MC) pattern, or 3-0 Monocryl in a simple interrupted (MI) pattern (n = 20 per group). Duration of closure was compared between groups. Tissues were tested under tension to failure, and mode of failure data were collected by video capture.

Pharmacokinetics of a modified, compounded theophylline product in dogs.

Theophylline is a commonly used bronchodilator drug for treatment of chronic canine bronchitis, but no formulations validated in dogs are currently available. An oral, modified and compounded theophylline product (MCT), which could fulfil this need, is available through a USP-compliant, veterinary compounding pharmacy; however, its pharmacokinetic properties are unknown. The aim of this study was to determine the pharmacokinetics of MCT.

Nasal hydropulsion: a novel tumor biopsy technique.

Intranasal tumors of dogs and cats pose a diagnostic and therapeutic challenge for small animal practitioners. Multiple nasal biopsy techniques have been described in the past. This report describes a simplified flushing technique to biopsy and debulk nasal tumors, which often also results in immediate clinical relief for the patient.

Nasopharyngeal turbinates in brachycephalic dogs and cats.

This retrospective study reports the presence and incidence of nasal turbinates in the nasopharynx (nasopharyngeal turbinates) in a population of brachycephalic dogs and cats exhibiting signs of upper respiratory disease. Medical records were reviewed for 53 brachycephalic dogs and 10 brachycephalic cats undergoing upper airway endoscopy. Nasopharyngeal turbinates were identified in 21% of brachycephalic animals, including 21% of dogs and 20% of cats.

Do corticomotoneuronal cells predict target muscle EMG activity?

Data from two rhesus macaques were used to investigate the pattern of cortical cell activation during reach-to-grasp movements in relation to the corresponding activation pattern of the cell's facilitated target muscles. The presence of postspike facilitation (PSpF) in spike-triggered averages (SpTAs) of electromyographic (EMG) activity was used to identify cortical neurons with excitatory synaptic linkages with motoneurons. EMG activity from 22 to 24 muscles of the forelimb was recorded together with the activity of M1 cortical neurons.

Objective: To evaluate the pharmacokinetics of a brand of extended-release theophylline tablets and capsules in healthy cats.

Design: Randomized 3-way crossover study.

Animals: 6 healthy cats.

Endoscopic bronchial anatomy in the cat.

The aim of this paper is to define the endoscopic bronchial anatomy of the cat and to adapt these findings to the bronchoscopic nomenclature previously described for the dog by Amis and McKiernan (Amis TC, McKiernan BC (1986) Systematic identification of endobronchial anatomy during bronchoscopy in the dog. American Journal of Veterinary Research 47(12), 2649-2657). In this study, the normal endoscopic bronchial anatomy was identified based on analysis of 10 air-dried feline lungs, two euthanased and eight healthy anesthetized cats using either a rigid or a flexible endoscope.

Neuromuscular electrical stimulation improves severe hand dysfunction for individuals with chronic stroke: a pilot study.

Restoring hand function is difficult post-stroke. We sought to determine if applying neuromuscular electrical stimulation (NMES) was beneficial for reducing severe hand impairments. Subjects with chronic stroke (N=8; 3 Fe, 5 M; 58.

Access to polling places in the 2004 Presidential election: the experience of one metropolitan midwestern city.

According to federal law, polling places must be accessible to persons with disabilities. The rate of compliance with these laws, however, is not known. Our purpose was to determine whether polling places in the Greater Kansas City area were physically accessible to persons with disabilities.

Investigation of pulmonary deposition of a nebulized radiopharmaceutical agent in awake cats.

Animals: 6 healthy adult dogs.

Prevalence of gastric lesions in racing Alaskan sled dogs.

Human and equine athletes are reported to have a high prevalence of gastric disease, and anecdotal evidence suggests a similar phenomenon applies to racing sled dogs. To investigate the prevalence of gastric disease in racing sled dogs, we conducted 2 gastroscopy studies on dogs competing in the annual Iditarod Sled Dog Race. A pilot study of dogs that were either dropped from the 2000 Iditarod Sled Dog Race because of illness or that finished the race indicated that, approximately 5 days after competing, 10 of 28 dogs (35%) had endoscopic evidence of gastric ulceration, erosion, or hemorrhage.

The effects of doxapram hydrochloride (dopram-V) on laryngeal function in healthy dogs.

Laryngeal dysfunction is assessed most accurately by direct visualization of the larynx under a light plane of anesthesia. If the plane of anesthesia used is too deep, laryngeal structures may appear paralyzed and remain in a paramedian position. Doxapram hydrochloride is a known respiratory stimulant.

Racing Alaskan sled dogs as a model of "ski asthma".

Athletes who play sports in cold weather, particularly skaters and cross-country skiers, have an increased prevalence of lower airway disease that is hypothesized to result from repeated penetration of incompletely conditioned air into the lung periphery. In this study, we investigated the hypothesis that canine winter athletes also suffer from increased prevalence of lung disease secondary to hyperpnea with cold air. Bronchoscopy and bronchoalveolar lavage was conducted in elite racing sled dogs 24 to 48 hours after completion of a 1,100-mile endurance race.

Diagnosis and treatment of canine chronic bronchitis. Twenty years of experience.

Chronic bronchitis is a frustrating disease because the cause is rarely determined, the pathologic changes that accompany and define the disease are usually nonreversible and often progress to life-threatening disorders, and there is a lack of direct scientific evidence for the treatment recommendations that have been offered for the management of this disease in dogs. This article reviews the pathophysiology, clinical presentation, diagnosis, and evaluation of chronic bronchitis in dogs. Important diagnostic tools for use in diagnosis are discussed, including clinical pathology, chest radiographs, and culture and cytology of airway fluid samples.

Nonenteric Escherichia coli isolates from dogs: 674 cases (1990-1998).

Objective: To determine nonenteric sites associated with Escherichia coli isolates in dogs and the antimicrobial susceptibilities of the isolates.

Design: Retrospective study.

Sample Population: 17,000 canine specimens.

Quantitative bacterial cultures and cytological examination of bronchoalveolar lavage specimens in dogs.

Cytology and quantitative bacterial cultures of lower respiratory tract secretions are widely used in human medicine to differentiate airway infection from simple bacterial colonization. A retrospective study was conducted to determine the usefulness of quantitative aerobic cultures and Gram stain intracellular bacteria counts from bronchoalveolar lavage (BAL) specimens in dogs in diagnosing lower respiratory tract infection (LRTI) and to determine whether chronic bronchitis is associated with marked bacterial growth in dogs. The threshold determined to define clinically relevant bacterial growth was 1.

Correlations between corticomotoneuronal (CM) cell postspike effects and cell-target muscle covariation.

The presence of postspike facilitation (PSpF) in spike-triggered averages of electromyographic (EMG) activity provides a useful means of identifying cortical neurons with excitatory synaptic linkages to motoneurons. Similarly the presence of postspike suppression (PSpS) suggests the presence of underlying inhibitory synaptic linkages. The question we have addressed in this study concerns the extent to which the presence and strength of PSpF and PSpS from corticomotoneuronal (CM) cells correlates with the magnitude of covariation in activity of the CM cell and its target muscles.

Calcinosis cutis associated with systemic blastomycosis in three dogs.

Three dogs treated for systemic blastomycosis with intravenous amphotericin B (one case) or amphotericin B lipid complex (two cases) developed mild to severe calcinosis cutis two to six weeks after the initiation of treatment. Abnormalities in serum calcium and phosphorus during treatment for blastomycosis or at the time of diagnosis of calcinosis cutis were slight or absent. The calcification was not associated with lesions of cutaneous blastomycosis.

Motor skill impairment in SIV-infected rhesus macaques with rapidly and slowly progressing disease.

A number of studies have shown that simian immunodeficiency virus (SIV) infection in rhesus macaques parallels many aspects of HIV disease in humans. The purpose of this study was to further characterize the rhesus macaque infected with neurovirulent SIV as a model of neuroAIDS. Using a motor skill task, our objective was to detect SIV-related movement impairments in behaviorally trained macaques.
