Evaluating vaccination strategies to control foot-and-mouth disease: a country comparison study.

Vaccination is increasingly being recognised as a potential tool to supplement 'stamping out' for controlling foot-and-mouth disease (FMD) outbreaks in non-endemic countries. Infectious disease simulation models provide the opportunity to determine how vaccination might be used in the face of an FMD outbreak. Previously, consistent relative benefits of specific vaccination strategies across different FMD simulation modelling platforms have been demonstrated, using a UK FMD outbreak scenario.

Influence of age on histologic outcome of cervical intraepithelial neoplasia during observational management: results from large cohort, systematic review, meta-analysis.

Aim of this study was to investigate the histologic outcome of cervical intraepithelial neoplasia (CIN) during observational management. Consecutive women with histologically verified CIN and observational management were included. Histologic findings of initial and follow-up visits were collected and persistence, progression and regression rates at end of observational period were assessed.

Dual Radial Styloid and Volar Plating for Unstable Fractures of the Distal Radius.

As the operative management of displaced distal radius fractures evolves, intraoperative techniques and fixation strategies evolve as well. Achieving and maintaining an acceptable reduction is paramount but can be difficult with particular fracture patterns. In this article, we describe the use of a radial column plate as a reduction tool in the management of unstable distal radius fractures, along with clinical and radiographic clinical outcomes.

SURGICAL MANAGEMENT OF UTERINE LESIONS IN TWO CAPTIVE ORANGUTANS ( PONGO SPP.).

Uterine lesions in two orangutans were effectively managed with surgical intervention. A 26-year-old hybrid orangutan ( Pongo spp.) was diagnosed with uterine adenomyosis based on advanced imaging.

HISTOPATHOLOGIC CHARACTERISTICS OF THYROID GLAND NEOPLASMS IN THOMSON'S GAZELLES ( EUDORCUS THOMSONII).

Published reports of neoplasms in Thomson's gazelles ( Eudorcas thomsonii) are very rare, but thyroid tumors were the most common neoplasm of this species, accounting for 12% of reported pathologies in a 1998-2012 retrospective study of cases submitted for histologic review of grossly enlarged thyroid glands. This report describes the histological and immunohistochemical characteristics of thyroid neoplasms in 10 Thomson's gazelles from five different zoological collections. Neoplasms were submitted as biopsies from six gazelles or collected during necropsy from four gazelles.

IRON STORAGE DISEASE IN AFRICAN GREY PARROTS ( PSITTACUS ERITHACUS) EXPOSED TO A CARNIVOROUS DIET.

Within a 2-wk period, three African grey parrots ( Psittacus erithacus) presented for emergency treatment. All three parrots had depressed behavior, an inability to fly, and significant weight loss. Plasma chemistry abnormalities included severe hypoproteinemia and elevated liver enzymes in all parrots.

CLINICOPATHOLOGIC FEATURES OF INFECTION WITH NOVEL BRUCELLA ORGANISMS IN CAPTIVE WAXY TREE FROGS ( PHYLLOMEDUSA SAUVAGII) AND COLORADO RIVER TOADS ( INCILIUS ALVARIUS).

Two novel and distinct Brucella strains were recovered from 5 of 10 adult, sex undetermined, captive waxy tree frogs ( Phyllomedusa sauvagii) and two of five adult, sex undetermined, captive Colorado river toads ( Incilius alvarius) held in a zoologic collection with clinical and pathologic findings of bacterial disease. These amphibians originated from three separate private breeding facilities over several years and exhibited disease 9-49 mo following release from quarantine. Common presenting signs were vague but included focal abscessation, weight loss, change in coloration, anorexia, and decreased perching.

The Moderating Effect of Self-Reported State and Trait Anxiety on the Late Positive Potential to Emotional Faces in 6-11-Year-Old Children.

The emergence of anxiety during childhood is accompanied by the development of attentional biases to threat. However, the neural mechanisms underlying these biases are poorly understood. In addition, previous research has not examined whether state and trait anxiety are independently associated with threat-related biases.

Individual differences in search and monitoring for color targets in dynamic visual displays.

Many real-world tasks now involve monitoring visual representations of data that change dynamically over time. Monitoring dynamically changing displays for the onset of targets can be done in two ways: detecting targets directly, post-onset, or predicting their onset from the prior state of distractors. In the present study, participants' eye movements were measured as they monitored arrays of 108 colored squares whose colors changed systematically over time.

Discrimination between bycatch and other causes of cetacean and pinniped stranding.

The challenge of identifying cause of death in discarded bycaught marine mammals stems from a combination of the non-specific nature of the lesions of drowning, the complex physiologic adaptations unique to breath-holding marine mammals, lack of case histories, and the diverse nature of fishing gear. While no pathognomonic lesions are recognized, signs of acute external entanglement, bulging or reddened eyes, recently ingested gastric contents, pulmonary changes, and decompression-associated gas bubbles have been identified in the condition of peracute underwater entrapment (PUE) syndrome in previous studies of marine mammals. We reviewed the gross necropsy and histopathology reports of 36 cetaceans and pinnipeds including 20 directly observed bycaught and 16 live stranded animals that were euthanized between 2005 and 2011 for lesions consistent with PUE.

The Effect of Soft Tissue Injuries on Clinical Outcomes After Tibial Plateau Fracture Fixation.

Objective: To determine if ligamentous and meniscal injuries as determined by initial magnetic resonance imaging altered clinical outcomes after the fixation of tibial plateau fractures.

Design: Comparative cohort study.

Setting: Academic level I trauma center.

Hormonal manipulation after surgery for catamenial pneumothorax.

A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether hormonal manipulation with gonadotrophin-releasing hormone analogues reduces the risk of recurrent catamenial pneumothorax after surgery, compared with surgery alone. Altogether 819 papers were found using the reported search, of which 7 represented the best evidence to answer the clinical question.

A late presentation of Loeys-Dietz syndrome associated with an aortic root aneurysm.

Loeys-Dietz syndrome (LDS) is characterised by a mutation in the transforming growth factor beta receptor, and is strongly associated with aortic aneurysms and rupture. Most cases of LDS present in the second decade of life, with the average life expectancy being 37 years. We report a case of suspected LDS (owing to significant family history of the disorder) that presented in the seventh decade of life.

A systematic review and meta-analysis of mechanical vs biological composite aortic root replacement, early and 1-year results.

Objective: Composite aortic root replacement is a standard procedure for various aortic root pathologies. This systematic review was set to identify the postoperative outcomes for composite mechanical root replacement (mCRR) compared to composite biological root replacement (bCRR).

Methods: We systematically reviewed four major databases for all papers assessing outcomes in composite root replacement.

Percutaneous Epiphysiodesis Using Transphyseal Screws: a Case Series Demonstrating High Efficacy.

Background: Percutaneous epiphysiodesis using transphyseal screws (PETS) has been associated with implant failure, implant prominence, angular deformities, and delayed growth inhibition.

Questions/purposes: The aim of this study was to assess the complication rate and efficacy (defined as actual growth inhibition divided by expected growth inhibition) of PETS and to identify factors associated with improved efficacy.

Methods: Patients who underwent distal femoral and/or proximal tibial PETS between January 2007 and June 2014 were identified.

New supporting ligands in actinide chemistry: tetramethyltetraazaannulene complexes with thorium and uranium.

We report the synthesis, characterization, and preliminary reactivity of new heteroleptic thorium and uranium complexes supported by the macrocyclic TMTAA ligand (TMTAA = Tetramethyl-tetra-aza-annulene). The dihalide complexes Th(TMTAA)Cl(THF) (1), [UCl(TMTAA)] (2) and U(TMTAA)I (3) are further functionalized to the Cp* derivatives ThCp*(TMTAA)Cl (4), UCp*(TMTAA)Cl (5) and UCp*(TMTAA)I (6) (Cp* = pentamethylcyclopentadienide). Compounds 4-6 are also obtained through a one-pot reaction from standard thorium(iv) and uranium(iv) starting materials, Li2TMTAA and KCp*.

Fistula of right internal thoracic artery as a rare cause of chest pain.

Variation in the origin of the internal thoracic arteries has been previously described and reported in the literature; however, there has been no report of an anomalous termination of the right internal thoracic artery into the pulmonary vein persisting and presenting in adult life. We report the case of the right internal thoracic artery originating from the first part of subclavian artery but terminating into the right superior pulmonary vein that presented during the third decade of life.

Anomalous Right Internal Thoracic Artery Terminating in the Right Superior Pulmonary Vein.

Variation in the origin of the internal thoracic arteries has been previously described and reported in the literature; however, there has been no report of an anomalous termination of the right internal thoracic artery (RITA) in the pulmonary vein persisting and presenting in adult life. We report the case of a right internal thoracic artery originating from the first part of the subclavian artery but terminating in the right superior pulmonary vein that presented during the third decade of life.

DISSEMINATED TOXOPLASMOSIS IN A CAPTIVE ADULT DROMEDARY CAMEL (CAMELUS DROMEDARIUS).

An 11-yr-old dromedary camel (Camelus dromedarius) at a zoo in south Florida presented with diarrhea while being treated with enrofloxacin and dexamethasone for a chronic skin condition. Three weeks after initiation of therapy with dexamethasone, the camel developed diarrhea, which worsened despite treatment with antibiotics. The animal became increasingly debilitated, developed hemorrhagic diarrhea, declined rapidly over the next 3 days, and died despite aggressive fluid therapy and supportive care.

Thorium Metallacycle Facilitates Catalytic Alkyne Hydrophosphination.

The bis(NHC)borate-supported thorium-bis(mesitylphosphido) complex (1) undergoes reversible intramolecular C-H bond activation enabling the catalytic hydrophosphination of unactivated internal alkynes. Catalytic and stoichiometric experiments support a mechanism involving reactive Th-NHC metallacycle intermediates (Int and 2).

Benzoquinonoid-bridged dinuclear actinide complexes.

We report the coordination chemistry of the tripodal tris[2-amido(2-pyridyl)ethyl]amine ligand, L, with thorium(iv) and uranium(iv). Using a salt-metathesis strategy from the potassium salt of this ligand, K3L, new actinide complexes were isolated, namely the dimeric thorium complex [ThCl(L)] (1) and the monomeric uranium complex UI(THF)(L) (2); under different crystallisation conditions, the dimeric uranium complex is also isolated, [UI(L)] (2-dimer). With the aim of studying electronic phenomena such as magnetic exchange between two actinide ions, we have synthesised the first examples of dinuclear, quinoid-bridged actinide complexes from dianionic 2,5-bis[2,6-(diisopropyl)anilide]-1,4-benzoquinone (QDipp) and 2,5-bis[2-(methoxy)anilide]-1,4-benzoquinone (QOMe) ligands.

Missed aortic valve endocarditis resulting in complete atrioventricular block and redo mechanical valve replacement.

Infective endocarditis is a rare disease associated with high morbidity and mortality. As a result, early diagnosis and prompt antibiotic treatment with or without surgical intervention is crucial in the management of such condition.We report a case of missed infective endocarditis of the aortic valve.

Acute disseminated mycobacteriosis in captive Atlantic guitarfish ( Rhinobatos lentiginosus).

An adult female captive-born Atlantic guitarfish ( Rhinobatos lentiginosus) was found acutely moribund on exhibit and died soon after presentation. Abnormalities on autopsy were focal cutaneous erythema on the tail, a small liver, many variably sized friable ovarian follicles, and coelomic effusion. Histologic examination revealed systemic bacterial embolization, and yolk coelomitis with minimal associated inflammation and some mineralization.

SUCCESSFUL MANAGEMENT OF CECAL PERFORATION AND FOCAL PERITONITIS IN A GORILLA (GORILLA GORILLA GORILLA).

An 18-yr-old female Western lowland gorilla ( Gorilla gorilla gorilla) presented with acute-onset severe lethargy, bloody vaginal discharge, decreased appetite, and an abnormal posture. The gorilla was diagnosed with a ruptured cecal blind sac with severe adhesions to the right ovary. A typhlectomy and unilateral ovariectomy were performed.
