Association between previous splenectomy and gastric dilatation-volvulus in dogs: 453 cases (2004–2009)
Authors: Sartor Angela J. , Bentley Adrienne M. , Brown Dorothy C. 
Published: May 2013

Abstract
Objective—To evaluate the association between previous splenectomy and gastric dilatation-volvulus (GDV) in dogs.
Design—Multi-institutional retrospective case-control study.
Animals—151 dogs treated surgically for GDV and 302 control dogs with no history of GDV.
Procedures—Computerized records of dogs evaluated via exploratory laparotomy or abdominal ultrasonography were searched, and dogs with GDV and dogs without GDV (control dogs) were identified. Two control dogs were matched with respect to age, body weight, sex, neuter status, and breed to each dog with GDV. Data were collected on the presence or absence of the spleen for both dogs with GDV and control dogs. Conditional logistic regression analysis was used to investigate the association of previous splenectomy with GDV.
Results—6 (4%) dogs in the GDV group and 3 (1%) dogs in the control group had a history of previous splenectomy. The odds of GDV in dogs with a history of previous splenectomy in this population of dogs were 5.3 times those of dogs without a history of previous splenectomy (95% confidence interval, 1.1 to 26.8).
Conclusions and Clinical Relevance—For the patients in the present study, there was an increased odds of GDV in dogs with a history of splenectomy. Prophylactic gastropexy may be considered in dogs undergoing a splenectomy, particularly if other risk factors for GDV are present.
Adrenal gland function in a dog following unilateral complete adrenalectomy and contralateral partial adrenalectomy
Authors: Larson Ross N. , Schmiedt Chad W. , Wang Andrea , Lawrence Jessica , Howerth Elizabeth W. , Holmes Shannon P. , Grey Susan W. 
Published: May 2013

Abstract
Case Description—A 40.3-kg (88.7-lb) 6-year-old spayed female Labrador Retriever was evaluated because of acute unilateral epistaxis.
Clinical Findings—During the initial evaluation of the dog, systemic hypertension and a left adrenal gland mass were detected. The left adrenal gland mass was surgically removed; results of histologic examination of the mass indicated it was a pheochromocytoma. Ten months later, the dog was evaluated because of persistent systemic hypertension and development of polyuria, polydipsia, and excessive panting. Abdominal ultrasonography revealed a mass in the cranial aspect of the right adrenal gland; results of MRI suggested the mass was a malignant tumor.
Treatment and Outcome—Epistaxis resolved after treatment and resolution of severe systemic hypertension. A partial right adrenalectomy was performed to remove the right adrenal gland mass. Results of histologic examination of the mass indicated it was a well-differentiated carcinoma of the cortex of the adrenal gland. Results of ACTH stimulation tests after surgery indicated the dog had adequate adrenal gland function.
Clinical Relevance—Partial adrenalectomy may be a safe and feasible treatment option to preserve adrenal gland function in dogs with small eccentrically located adrenal gland masses, particularly for dogs that have undergone removal of the contralateral adrenal gland.
Cestode fauna of feral pigeons in Thessaloniki; Northern Greece
Authors: Diakou A. , Ptochos S. , Papadopoulos E. 
Published: May 2013

Abstract
The common pigeon (Columba livia) is adapted to a variety of habitats; including big cities and rural areas everywhere in the world. Several studies confirm that feral pigeons pose a considerable health risk to the livestock and human population. They may serve as a reservoir for several pathogenic agents that can be transmitted to poultry; wildlife; domesticated pets and humans. The aim of this survey was to investigate the cestode species present in feral pigeons in Thessaloniki; Northern Greece. A total of 136 adult feral pigeons were necropsied and the cestodes recovered were preserved for identification using morphological keys. Ninety-six (70.58 %) of them were found to be infected with cestode parasites; which were identified to be Raillietina spp.: 84 (61.76 %) were infected with R. echinobothrida; 20 (14.7 %) with R. cesticillus and 8 (5.88%) with R. tetragona. Single infection was recorded in 80 birds (83.3 % of the infected population); while a significantly lower number; i.e. 16 birds (16.7 %); had a mixed infection with R. echinobothrida and R. cesticillus (p ≤ 0.05). The current study confirms that feral pigeons in Northern Greece are heavily infected with cestode parasites. Therefore; it was concluded that feral pigeon management programmes and public education should be implemented to reduce the risk of a pigeon-to-human or livestock transmission of pathogenic agents and parasites in the country.
Subulura mackoi n. sp. (Nematoda: Subuluridae) and the zoogeography of subulurids parasitizing birds
Authors: Baruš V. , Mašová Š. , Koubková B. , Sitko J. 
Published: May 2013

Abstract
A new nematode species, Subulura mackoi n. sp., is described based on specimens from the colon and caecum of the Eurasian Scops Owl Otus scops (L.) (Aves: Strigiformes) from the Czech Republic, collected in 2011. Males are characterized by 10 pairs of caudal papillae, a single papilla on the upper lip of the cloaca, and small unequal spiculae; female distinguishing features are body length, distance of the vulva from the anterior extremity, tail length, and egg dimension.
Analysis of the zoogeographical distribution and host specialization (in the bird orders) of 68 valid species from the genus Subulura Molin, 1860 shows significantly high species diversity in the tropical zones. Only one species, S. brumpti, is a cosmopolitan parasite of Gallus gallus f. domestica and other domesticated gallinaceous birds. Zoogeographical-host interactions may be utilized to support the identification of morphospecies of the genus Subulura.

Abstract
In this research, a total of 298 Eurasian marsh frogs, Pelophylax ridibundus (Pallas, 1771) were collected from different localities in Denizli province (Inner-west Anatolia Region, the eastern part of Aegean Region) Turkey between 2006 and 2009 and examined for helminths. Of 262 (87.91 %) Pelophylax ridibundus samples were infected with one or more helminths. Pelophylax ridibundus harbored eight species of digeneans (Diplodiscus subclavatus, Gorgoderina vitelliloba, Gorgodera cygnoides, Pleurogenoides medians, Prosotocus confusus, Skrjabinoeces breviansa, Encyclometra colubrimurorum and Ophistoglyhe ranae), one species of cestode (Nematotaenia dispar), two species of acanthocephalans (Acanthocephalus ranae and Pomphorhynchus laevis), and six species of nematodes (Rhabdias bufonis, Oswaldocruzia filiformis, Cosmocerca ornata, Oxysomatium brevicaudatum, Eustrongylides sp. and Abbreviata sp.). P. ridibundus represents a host record for Nematotaenia dispar in Turkey.

The Clown’s Lost Twin: Messianic Moments in Hanoch Levin’s Drama
Authors: Lipshitz Yair 
Published: May 2013

ABSTRACT: During the last decade of the twentieth century, leading Israeli playwright Hanoch Levin has returned several times to the issue of redemption and the figure of the Messiah, both heavily laden with political-theological meanings in Israeli culture. The article explores Levin’s messianic moments as an alternative to the prominent Israeli discourses regarding messianism. Instead of entirely debunking the Jewish messianic tradition, as other Israeli playwrights of the period have done (and while scathingly criticizing it), Levin recharges this tradition with new political and theatrical meanings. Levin’s drama includes a line of weak, seemingly “failing” Messiahs and, through them, asks questions about the conceptualization of dramatic time and the power structures of spectatorship, within and without the theatre.
Hydrocephalus after arteriovenous malformation rupture
Authors: Gross Bradley A. , Rosalind Lai Pui Man , Du Rose 
Published: May 2013

Object
The rates and risk factors for external ventricular drain (EVD) placement and long-term shunt dependence in patients with ruptured arteriovenous malformations (AVMs) have not been systematically studied. In this study the authors evaluated the rates of EVD placement and shunt dependence, and risk factors for them, in a cohort of patients with ruptured AVMs.

Methods
The records of 87 consecutive patients with ruptured AVMs were reviewed for patient demographics, hemorrhage pattern, AVM angioarchitectural features, and surgical treatment. Univariate and multivariate logistic regression analyses were performed to evaluate risk factors for EVD placement, permanent shunt dependence, and long-term outcome (as measured by the modified Rankin Scale).

Results
Thirty-eight patients (44%) required EVD placement, and 16 (18%) required a permanent shunt. Statistically significant risk factors for EVD placement in the univariate analysis included initial Glasgow Coma Scale (GCS) score (p = 0.002), the presence of intraventricular hemorrhage (IVH; p < 0.001), AVM-associated aneurysms (p = 0.002), and early surgery (p = 0.01). Multivariate analysis revealed only AVM-associated aneurysms as statistically significant (p = 0.006). Risk factors for shunt placement included initial GCS score (p = 0.003), IVH (p = 0.01), deep supratentorial location (p = 0.034), and associated aneurysms (p = 0.03). Multivariate analysis revealed initial GCS score as a statistically significant risk factor (p = 0.041) as well as a strong trend for associated aneurysms (p = 0.06). Patient age, sex, associated subarachnoid hemorrhage, AVM grade, AVM size, and deep venous drainage were not associated with EVD placement or long-term shunt dependence.

Conclusions
Hydrocephalus from AVM rupture was associated with initial GCS score, IVH, and AVM-associated aneurysms. Arteriovenous malformations with associated aneurysms thus not only have a greater risk of hemorrhage but also a greater risk of hemorrhage-associated morbidity as a result of hydrocephalus.
Modern intraoperative imaging modalities for the vascular neurosurgeon treating intracerebral hemorrhage
Authors: Goren Oded , Monteith Stephen J. , Hadani Moshe , Bakon Mati , Harnof Sagi 
Published: May 2013

This paper reviews the current intraoperative imaging tools that are available to assist neurosurgeons in the treatment of intracerebral hemorrhage (ICH). This review shares the authors' experience with each modality and discusses the advantages, potential limitations, and disadvantages of each.
Surgery for ICH is directed at blood clot removal, reduction of intracranial pressure, and minimization of secondary damage associated with hematoma breakdown products. For effective occlusion and safe obliteration of vascular anomalies associated with ICH, vascular neurosurgeons today require a thorough understanding of the various intraoperative imaging modalities available for obtaining real-time information. Use of one or more of these modalities may improve the surgeon's confidence during the procedure, the patient's safety during surgery, and surgical outcome.
The modern techniques discussed include 1) indocyanine green–based video angiography, which provides real-time information based on high-quality images showing the residual filling of vascular pathological entities and the patency of blood vessels of any size in the surgical field; and 2) intraoperative angiography, which remains the gold standard intraoperative diagnostic test in the surgical management of cerebral aneurysms and arteriovenous malformations. Hybrid procedures, providing multimodality image-guided surgeries and combining endovascular with microsurgical strategies within the same surgical session, have become feasible and safe. Microdoppler is a safe, noninvasive, and reliable technique for evaluation of hemodynamics of vessels in the surgical field, with the advantage of ease of use. Intraoperative MRI provides an effective navigation tool for cavernoma surgery, in addition to assessing the extent of resection during the procedure. Intraoperative CT scanning has the advantage of very high sensitivity to acute bleeding, thereby assisting in the confirmation of the extent of hematoma evacuation and the extent of vascular anomaly resection. Intraoperative ultrasound aids navigation and evacuation assessment during intracerebral hematoma evacuation surgeries. It supports the concept of minimally invasive surgery and has undergone extensive development in recent years, with the quality of ultrasound imaging having improved considerably.
Image-guided therapy, combined with modern intraoperative imaging modalities, has changed the fundamentals of conventional vascular neurosurgery by presenting real-time visualization of both normal tissue and pathological entities. These imaging techniques are important adjuncts to the surgeon's standard surgical armamentarium. Familiarity with these imaging modalities may help the surgeon complete procedures with improved safety, efficiency, and clinical outcome.

Published: May 2013

Object
In this paper the authors' goal was to review the clinical features and outcome of patients with intracranial dural arteriovenous fistulas (DAVFs) who presented with hemorrhage.

Methods
A retrospective study of 28 patients with DAVFs who presented with intracranial hemorrhage to 2 separate institutions was performed. The information reviewed included clinical presentation, location and size of hemorrhage, angiographic features, treatment, and clinical and radiologically documented outcomes. Clinical and radiological follow-up were available in 27 of 28 patients (mean follow-up 17 months).

Results
The vast majority of patients were male (86%), and the most common presenting symptom was sudden-onset headache. All DAVFs had cortical venous drainage, and about one-third were associated with a venous varix. The most common location was tentorial (75%). Treatment ranged from endovascular (71%), surgical (43%), Gamma Knife surgery (4%), or a combination of modalities. The majority of fistulas (75%) were completely obliterated, and most patients experienced excellent clinical outcome (71%, modified Rankin Scale score of 0 or 1). There were no complications in this series.

Conclusions
Case series, including the current one, suggest that the vast majority of patients who present with intracranial hemorrhage from a DAVF are male. The most common location for DAVFs presenting with hemorrhage is tentorial. Excellent outcomes are achieved with individualized treatment, which includes various therapeutic strategies alone or in combination. Despite the hemorrhagic presentation, almost two-thirds of patients experience a full recovery with no or minimal residual symptoms.

Published: May 2013

BackgroundGuidelines recommend rest periods between nursing interventions for patients with a neurologic diagnosis but do not specify a safe number of interventions.ObjectivesTo examine the physiological stress response to clustered nursing interventions in neurologic patients receiving mechanical ventilation.MethodsProspective, comparative, descriptive design to examine effects of clustered interventions (≥6 interventions in a single nursing interaction) versus nonclustered interventions on patients’ stress. Stress response was defined as a 10% change in end-tidal carbon dioxide from before the interaction to (1) 5 and 10 minutes after the start of the interaction, (2) at the end of the interaction, and (3) 15 minutes after the interaction.ResultsThe mean percent change in end-tidal carbon dioxide at 5 minutes differed significantly between patients with clustered interventions and patients with nonclustered interventions (6.7% vs −0.2%; P = .001). Patients with clustered interventions were significantly more likely than patients with low clustering to exhibit a stress response at 5 minutes (24.3% vs 0%; P = .01).ConclusionsNeurologic patients receiving mechanical ventilation who experienced 6 or more clustered nursing interventions showed a higher mean change in end-tidal carbon dioxide than did patients who received fewer than 6 clustered interventions. These findings suggest that providing fewer interventions during 1 nursing interaction may minimize induced stress in neurologic patients receiving mechanical ventilation.
What Do Veterans Service Organizations' Web Sites Say about Tobacco Control?
Authors: Poston Walker S. C. , Haddock Christopher K. , Jahnke Sara A. , Jitnarin Nattinee 
Published: May 2013

Purpose. Little is known about veterans service organizations (VSOs) and their perspectives on veterans smoking or military tobacco control. Veterans have high smoking rates and many started smoking in the military, where a culture promoting use exists. Design. A qualitative content analysis of VSO Web sites was conducted to classify health topics and identify tobacco-related information. Setting. Web sites were coded by trained raters from January to June of 2011. Data were entered, cleaned, and analyzed from July 2011 to January 2012. Subjects. Twenty-four active VSO Web sites meeting inclusion criteria were rated independently. Measures. A comprehensive form was used to code 15 veteran-relevant health topics across multiple content areas/domains within the Web sites. Raters achieved 94.5% interrater agreement over nearly 5000 data points. Analysis. Health content was coded as present or not within multiple VSO Web site areas/domains. The frequency of coverage by each VSO Web site and the number of VSO Web sites that mentioned a health topic in different Web site areas/domains were tabulated. Results. A total of 277 health topics were addressed, with the top five being insurance/Tricare/Veterans Administration issues (28.2%), posttraumatic stress disorder (PTSD; 15.5%), disability/amputation/wounds (13.4%), Agent Orange (10.5%), and traumatic brain injury (9.0%). Tobacco was mentioned four times (1.4%) across all 24 VSO Web sites, and smoking cessation was never addressed. Conclusion. VSO Web sites provide little information on tobacco-related topics and none offered information about smoking cessation. Given the high rates of tobacco use among veterans and active-duty service members, and the interaction between smoking and PTSD symptoms and treatment outcomes, VSOs should consider making tobacco control and smoking cessation higher-priority health issues on their Web sites.

Published: May 2013

AbstractPerforming catalytic enantioselective reactions, especially enantioselective carbon‐carbon bond forming reactions, in water without using any organic solvents is one of the important goals in modern asymmetric synthesis. Herein, we report an efficient enantioselective micellar catalytic approach for the 1,4‐addition of arylboronic acids to cyclic ketones. Noteworthy, applying the same catalytic system we have also developed the first addition of boronic acids to the more challenging α‐keto carbonyl compounds in water, affording tertiary carbinols with high yields and high enantioselectivities. Beside the mild conditions used, the reported processes use as catalyst precursor the robust sulfinamido‐olefin mixed ligand 1 obtained on a multigram scale and in one step from a sugar‐derived sulfinate ester.

Published: May 2013

AbstractPolylactic acid (PLA) films were surface modified by gamma ray irradiation‐induced grafting of N‐vinyl pyrrolidone (NVP). The in vitro degradation behavior of polylactic acid grafting N‐vinyl pyrrolidone (PLA‐g‐PVP) copolymer was analyzed in terms of weight loss, molecular weight, and thermal properties. Grafting NVP significantly accelerated the degradation of PLA. The mass losses of the copolymers, which were less than that of pure PLA at the beginning of the degradation period, sharply accelerated with increasing degradation time. Moreover, the crystallization temperature decreased with increasing degradation time in the same graft ratio, and the degree of crystallinity increased. Cytotoxicity experiments and animal experiments in vivo were carried out to evaluate the biocompatibility of PLA‐g‐PVP copolymer. Varying graft ratios of PVP could control the degradation rate of copolymers, and thus broadening the applications of this material, such as in tissue engineering scaffolds, drug delivery, and prevention of postsurgical adhesion. © 2013 Wiley Periodicals, Inc.
