Bilateral lumbar hernias in a domestic shorthair cat
Authors: Olin Shelly J. , Holmes Shannon P. , Jeffs Ashley , Cornell Karen K. 
Published: November 2012

Abstract
Case Description—A 2.8-kg (6.1-lb) 4-month-old sexually intact female domestic shorthair cat was referred for evaluation of bilateral, subcutaneous lumbar masses that were presumed to be the kidneys.
Clinical Findings—Physical examination findings included 2 mobile, nonpainful, 3×3-cm, bilaterally symmetric masses in the dorsolateral lumbar region. Abdominal radiography, ultrasonography, and CT confirmed bilateral body wall defects with renal herniation. Serum biochemistry profile, urinalysis, and excretory urography confirmed normal renal function.
Treatment and Outcome—Exploratory laparotomy, reduction of the kidneys, repair of the body wall defects, bilateral nephropexy, and ovariohysterectomy were performed. There were no perioperative complications.
Clinical Relevance—Lumbar hernia has not been reported previously in a cat. It is important for veterinarians to be aware that although rare, lumbar hernia should be included in the list of differential diagnoses for a lumbar mass or signs of chronic lumbar pain in cats.
Effects of yearling sale purchase price, exercise history, lameness, and athletic performance on purchase price of Thoroughbreds at 2-year-old in-training sales
Authors: Preston Stephanie A. , Brown Murray P. , Chmielewski Terese L. , Trumble Troy N. , Zimmel Dana N. , Hernandez Jorge A. 
Published: November 2012

Abstract
Objective—To determine the effects of yearling sale purchase price, exercise history, lameness, and athletic performance (speed) on purchase price of 2-year-old in-training Thoroughbreds and to compare the distance exercised within 60 days prior to 2-year-old in-training sales between horses with high yearling sale purchase prices versus those with low yearling sale purchase prices and between horses with lameness during training and those without lameness during training.
Design—Prospective study.
Animals—51 Thoroughbreds.
Procedures—Thoroughbreds purchased at a yearling sale were trained prior to resale at 2-year-old in-training sales. Amount of exercise and lameness status during training and speed of horses at 2-year-old in-training sales were determined. Data were analyzed via the Wilcoxon rank sum test and ANOVA.
Results—Median purchase price of horses at 2-year-old in-training sales was $37,000. The 2-year-old in-training sale purchase price was associated with yearling sale purchase price and distance galloped within 60 days prior to and speed recorded at 2-year-old in-training sales.
Conclusions and Clinical Relevance—Horses with high yearling sale purchase prices typically had high 2-year-old in-training sale purchase prices, had low distances galloped within 60 days prior to 2-year-old in-training sales, and were classified as fast at 2-year-old in-training sales. Lameness alone was not associated with 2-year-old in-training sales purchase price. However, lameness was associated with a low distance galloped before 2-year-old in-training sales, particularly for horses with a high yearling sale purchase price; this finding suggested that yearling sale purchase price can affect training management decisions for horses with lameness.

Abstract
Objective—To determine the effects of various presale radiographic findings for Thoroughbreds sold at a yearling sale on 2-year-old racing performance of those horses.
Animals—397 Thoroughbreds.
Design—Cohort study.
Procedures—Thoroughbreds offered for sale at a Thoroughbred sales facility in Kentucky were selected via a randomization procedure. Effects of various presale radiographic findings on the following measures of 2-year-old racing performance were determined: having started a race and having placed (ie, finished in first, second, or third place) in a race at least once, total amount of money earned, and amount of money earned per start.
Results—Of the 397 horses, 192 (48%) started in at least 1 race during the 2-year-old racing year. The odds of failure to start a race as a 2-year-old were 1.78 times as great for horses with forelimb proximal sesamoid bone osteophytes or enthesophytes as for horses without this finding (95% confidence interval, 1.01 to 3.16). The odds of failure to start a race as a 2-year-old were 2.02 times as great for horses with hind limb proximal phalanx osteochondral fragments as for horses without this finding (95% confidence interval, 0.95 to 4.31), although this result was not significant. Radiographic findings did not have an effect on total amount of money earned, amount of money earned per start, or whether horses placed in a race.
Conclusions and Clinical Relevance—Presale radiographic detection of forelimb proximal sesamoid bone osteophytes or enthesophytes or hind limb proximal phalanx osteochondral fragments in yearlings were associated with failure to start a race during the 2-year-old racing year in study horses.

Published: November 2012

Abstract
Objective—To evaluate the effect of nutritional plane on health and performance of dairy calves after infection with Cryptosporidium parvum.
Design—Randomized, controlled trial.
Animals—20 Holstein bull calves.
Procedures—Calves were assigned to a higher plane of nutrition (HPN; 0.30 Mcal intake energy/kg of metabolic body weight using a 28% protein-20% fat milk replacer) or conventional nutrition (CN; 0.13 Mcal intake energy/kg of metabolic body weight using a 20% protein-20% fat milk replacer). Calves were inoculated with C parvum oocysts at 3 days old. Fecal and health scores, oocyst counts, weight gain, dry matter intake, and hematologic variables were measured for 21 days. Data were analyzed with nonparametric and regression methods.
Results—Body weight (day 1), serum total protein concentration (day 3), and PCV (day 3) were not different between groups. Oocyst shedding was not different between groups. The PCV was higher in the CN group (40%), compared with the HPN group (32%) at the end of the study. Fecal scores (FS) improved faster in the HPN group (median, −0.1 FS/feeding), compared with the CN group (median, −0.06 FS/feeding). The HPN calves had better average daily gain (ADG) than did CN calves (median, 433 g/d vs −48 g/d, respectively). Feed efficiency (ADG:dry matter intake ratio) was better for HPN calves than CN calves (median, 131.9 g/kg vs −31.4 g/kg).
Conclusions and Clinical Relevance—After a pathogen challenge, calves maintained hydration, had faster resolution of diarrhea, grew faster, and converted feed with greater efficiency when fed a higher plane of nutrition.

Published: November 2012

AbstractThe structure of styryl dye, 2-[(E)-2-(4-dipropylaminophenyl)-1-ethenyl]-1,3,3-trimethyl-3H-indolium chloride (I), was investigated using methods such as UV-VIS, fluorescence spectroscopy, and NMR (1H, 13C, APT, HMQC, COSY) and also by examining its electrochemical properties. A study of the acid-base properties revealed the existence of three different forms of the dye. The mechanisms of protolysis and hydrolysis are discussed. The reagent exists in a reactive single-charged form I + over a wide range of acidity (pH 4–11). The optimum analytical wavelength of the singlecharged form is 550 nm, where the molar absorptivity is 5.51 × 104 L mol−1 cm−1. The values of the optimum analytical wavelength and molar absorptivity of the protolysed and hydrolysed forms are: λ max(I-H2+) = 380 nm, ɛ(I-H2+) = 2.01 × 104 L mol−1 cm−1; λ max(I-OH) = 320 nm, ɛ(I-OH) = 1.12 × 104 L mol−1 cm−1. A theoretical study of the spectral and chemical properties of I was carried out by performing quantum chemical calculations.

Published: November 2012

BackgroundThe newly developed Brief–Balance Evaluation System Test (Brief-BESTest) may be useful for measuring balance and predicting falls in individuals with Parkinson disease (PD).ObjectivesThe purposes of this study were: (1) to describe the balance performance of those with PD using the Brief-BESTest, (2) to determine the relationships among the scores derived from the 3 versions of the BESTest (ie, full BESTest, Mini-BESTest, and Brief-BESTest), and (3) to compare the accuracy of the Brief-BESTest with that of the Mini-BESTest and BESTest in identifying recurrent fallers among people with PD.DesignThis was a prospective cohort study.MethodsEighty participants with PD completed a baseline balance assessment. All participants reported a fall history during the previous 6 months. Fall history was again collected 6 months (n=51) and 12 months (n=40) later.ResultsAt baseline, participants had varying levels of balance impairment, and Brief-BESTest scores were significantly correlated with Mini-BESTest (r=.94, P&lt;.001) and BESTest (r=.95, P&lt;.001) scores. Six-month retrospective fall prediction accuracy of the Brief-BESTest was moderately high (area under the curve [AUC]=0.82, sensitivity=0.76, and specificity=0.84). Prospective fall prediction accuracy over 6 months was similarly accurate (AUC=0.88, sensitivity=0.71, and specificity=0.87), but was less sensitive over 12 months (AUC=0.76, sensitivity=0.53, and specificity=0.93).LimitationsThe sample included primarily individuals with mild to moderate PD. Also, there was a moderate dropout rate at 6 and 12 months.ConclusionsAll versions of the BESTest were reasonably accurate in identifying future recurrent fallers, especially during the 6 months following assessment. Clinicians can reasonably rely on the Brief-BESTest for predicting falls, particularly when time and equipment constraints are of concern.
The Who, What, When, and How: Of Choosing a Dietetics Career
Authors: Lordly Daphne , Dubé Nicole 
Published: November 2012

Purpose: We describe factors influencing the career choices of students enrolled in Canadian dietetics programs.Methods: A survey was administered, in class or online, to core first- and fourth-year classes in seven dietetics programs in various provinces (n=397). Data were analyzed with the use of descriptive statistics. Chi-square testing for independence established significant relationships.Results: Students ranked personal satisfaction, job security, and a professional career as important general career outcomes. These factors were also perceived to be attainable through a dietetics career. The majority of students chose dietetics while they were enrolled in a post-secondary degree program (44%), were primarily influenced by family members (54%), and based their choice on information acquired through the media (50%). Motivations for choosing dietetics included an interest in nutrition (91%) and health (90%), and a desire to help others (82%). Younger students placed more importance on economic rewards and having a position of authority than did older students. Older students identified personal satisfaction as more important in career selection than did younger students. Female respondents placed higher value on job flexibility than did their male counterparts.Conclusions: Career choice is based on a variety of internal and external factors. Opportunities exist for strategic recruitment efforts by educators and the profession.
Surgical treatment of Chiari malformation with and without syringomyelia: experience with 177 adult patients
Authors: Batzdorf Ulrich , McArthur David L. , Bentson John R. 
Published: November 2012

Object
This study aims to show the relationship between clinical outcome in patients who underwent surgical decompression for Chiari malformation (CM) and postoperative imaging studies, with particular emphasis on the subarachnoid cisterns of the posterior fossa.

Methods
One hundred seventy-seven patients with CM, including 97 with syringomyelia, underwent posterior fossa decompressive surgery. Both the dura and arachnoid were opened in 150 of these patients, and 135 underwent reduction of the cerebellar tonsils. The patients' clinical signs and symptoms were evaluated at 2 time points after surgery. Their imaging studies were analyzed specifically for the size of the retrotonsillar and subtonsillar cisterns and the syringomyelic cavities. The authors evaluated the relationship between these imaging findings and clinical parameters.

Results
Clinical improvement correlated strongly with enlargement of the subarachnoid cisterns, and enlargement of the cisterns also correlated with reduction in size of the syrinx cavities. Symptoms related to syringomyelia responded to reduction in size of the syrinx cavities.

Conclusions
Surgical decompression of the posterior fossa should aim to create relatively large subarachnoid cisterns and reduce the size of the syrinx cavity. Reduction of the cerebellar tonsils by surgical means, together with duraplasty, achieves this goal and thereby improves the clinical outcome for patients with CM. An incidental observation of the study is that obesity increases the likelihood of headache in patients with CM.
Surgical treatment for vertebral artery–posterior inferior cerebellar artery aneurysms: special reference to the importance of the cerebellomedullary fissure dissection
Authors: Kawashima Masatou , Takase Yukinori , Matsushima Toshio 
Published: November 2012

Object
The cerebellomedullary fissure (CMF) is a space between the cerebellum and the medulla oblongata, which often adhere to each other. The purpose of the present study was to demonstrate the importance of the unilateral CMF dissection for clipping vertebral artery (VA)–posterior inferior cerebellar artery (PICA) aneurysms.

Methods
Five adult cadaveric specimens were studied after colored silicone was infused into the arteries and veins. The microsurgical anatomy of the CMF and the trans-CMF approach for VA-PICA aneurysm surgery were examined in stepwise dissections. In addition, 6 patients underwent surgery for VA-PICA saccular aneurysms (2 ruptured and 4 unruptured aneurysms) via posterolateral approaches, with wide opening of the unilateral CMF to obtain good visualization and a wide working space in the lateral part of the cerebellomedullary cistern. Clinical data including neurological and radiological findings and patient outcomes were analyzed in all 6 cases.

Results
In all cases, the aneurysm was successfully clipped and no permanent neurological deficits remained. The wide opening of the unilateral CMF on the lesion side made it possible to retract the inferolateral part of the cerebellum easily, provided a wide operative field in the cerebellomedullary cistern, and enabled successful clip placement without difficulty.

Conclusions
For safe and effective VA-PICA aneurysm surgery, it is very important to dissect the CMF on the lesion side as well as to remove the lateral part of the foramen magnum. Direct clip placement is very safe and useful in cases involving VA-PICA aneurysms.
The role of venous sinus outflow obstruction in pediatric idiopathic intracranial hypertension
Authors: Dwyer Christopher M. , Prelog Kristina , Owler Brian K. 
Published: November 2012

Object
The authors examined the role of venous sinus obstruction in the etiology of idiopathic intracranial hypertension (IIH) by reviewing more than 200 MR venograms performed in suspected cases of IIH.

Methods
Individual MR venograms performed in cases of suspected IIH at the Children's Hospital at Westmead in Sydney, Australia, were reviewed. The authors excluded cases in which an intervention was performed before the scan or a structural cause for venous obstruction was identified. Cases with confirmed hydrocephalus were also excluded.
For each of the 145 remaining scans, the authors completed a detailed review on a slice-by-slice basis of the 2D source images used to compile the rendered 3D MR venogram. The anatomical configuration of the dural venous sinuses and any areas of decreased flow in circulation were then noted. Where possible, they correlated their radiological findings with evidence of raised intracranial pressure based on LP opening pressures. They also reviewed a control group of 50 MR venograms.

Results
Seventy-six (52%) of 145 scans showed evidence of venous obstruction in the dominant-side circulation. Substantial nonphysiological collateral circulation was seen in 68% of cases with dominant-sided obstruction, suggesting a process of recanalization. In contrast, in the absence of dominant-sided obstruction, collateral circulation was uncommon.
In 27 cases, CSF opening pressure measurements were available. In 20 cases the opening pressures were in excess of 20 cm H2O. Of those, 17 demonstrated evidence of dominant-sided venous outflow obstruction. Among those cases, the median opening pressure was 34 cm H2O.
Dominant-sided venous outflow obstruction was seen in only 2 of 50 MR venograms in the control group. Furthermore, evidence of collateral circulation was also uncommon in the control group. There was a highly statistically significant difference between rates of dominant-sided venous obstruction in the suspected IIH and control groups (p ≤ 0.001).

Conclusions
A majority of patients presenting for investigation of suspected IIH demonstrated evidence of dominant-sided venous obstruction on MR venogram. In addition there was a high correlation between elevated CSF opening pressures and dominant-sided venous sinus obstruction. This correlation was further supported by evidence of collateral recanalization in patients with elevated CSF pressures and dominant-sided venous obstruction. A control group of 50 MR venograms indicated that dominant-sided venous outflow obstruction is an unlikely incidental finding, and a highly statistically significant difference was found between rates of obstruction in the suspected IIH and control groups.
Analysis of Magnetic Gradients to Study Gravitropism
Authors: Hasenstein Karl H. , John Susan , Scherp Peter , Povinelli Daniel , Mopper Susan 
Published: November 2012

• Premise of the study: Gravitropism typically is generated by dense particles that respond to gravity. Experimental stimulation by high‐gradient magnetic fields provides a new approach to selectively manipulate the gravisensing system.• Methods: The movement of corn, wheat, and potato starch grains in suspension was examined with videomicroscopy during parabolic flights that generated 20 to 25 s of weightlessness. During weightlessness, a magnetic gradient was generated by inserting a wedge into a uniform, external magnetic field that caused repulsion of starch grains. The resultant velocity of movement was compared with the velocity of sedimentation under 1 g conditions.• Results: The high‐gradient magnetic fields repelled the starch grains and generated a force of at least 0.6 g. Different wedge shapes significantly affected starch velocity and directionality of movement.• Conclusions: Magnetic gradients are able to move diamagnetic compounds under weightless or microgravity conditions and serve as directional stimulus during seed germination in low‐gravity environments. Further work can determine whether gravity sensing is based on force or contact between amyloplasts and statocyte membrane system.
Enfant freudien, enfant kleinien
Authors: Brun Danièle 
Published: November 2012

Il est nécessaire de mettre l’accent sur le double aspect de la confrontation entre l’enfant freudien et l’enfant kleinien, c’est-à-dire simultanément identificatoire et métapsychologique. Si Freud, dans les années vingt, prône la primauté du masochisme, Melanie Klein venue à la psychanalyse vers 1914, reste campée sur la primauté du sadisme. De là une relation précoce à la mère différente pour chaque enfant. De nos jours, la présence de l’enfant kleinien se mêle à celle de l’enfant freudien, dans le cas de l’analyse d’enfants et dans celle des adultes. Aussi est-il très enrichissant de constater l’apport ainsi que les incidences de l’analyse d’enfants quant à l’éclairage de larges pans de l’analyse d’adultes.
L'enfant, objet a de Lacan
Authors: Vanier Alain 
Published: November 2012

Le statut de l’enfant est un fil qui parcourt l’enseignement de Lacan. Avec l’objet a, il propose une réduction de l’alternative enfant comme phallus ou comme objet partiel, selon l’équation qu’il pose, à la suite de Freud, au début du premier séminaire : « enfant = phallus = excrément, etc. »
Qu'est-ce qu'un enfant ? De l'enfant phobique à l'enfant-fétiche
Authors: Zafiropoulos Markos 
Published: November 2012

On montrera dans cet article en quoi l’idéal de l’enfant roi des sociétés occidentales permet de mieux comprendre pourquoi le petit Hans – ou encore l’enfant phobique – avait vocation à devenir le paradigme de la clinique de l’enfant dans le champ psychanalytique. Il suffisait ici alors de replacer cette figure de l’enfant idéal (I) dans la longue durée pour montrer en quoi il ne s’agit pas là d’un universel, puis de se référer à l’anthropologie psychanalytique pour apercevoir comment l’enfant sorcier de la société Bakongo rejeté du social peut occuper la place du déchet fétichisé, c’est-à-dire celle de l’objet (a).
Les Enfants de « la Science »
Authors: Pesenti-Irrmann Marie 
Published: November 2012

Très tôt, Jacques Lacan a invité les psychanalystes à ne pas méconnaître les effets du social, du politique sur la subjectivité, allant jusqu’à définir, aux côtés de la névrose et de la psychose, une modalité particulière de rapport à la parole, déterminée par les « effets désubjectivants de la science ». Les nouvelles nomenclatures en cours aujourd’hui dans la clinique de l’enfant, les nouvelles institutions de contrôle social qu’elles ont suscitées et dont l’école d’aujourd’hui se fait le relais déploient cette objectivité à prétention scientifique et empêchent que la parole de l’enfant soit entendue. L’auteur se propose de montrer qu’un certain nombre d’outils fournis par Lacan, plus particulièrement à la fin de son œuvre, tels que l’importance accordée à la jouissance, la fonction du « nommé à » se substituant à celle Nom-du-Père, l’écriture d’un cinquième discours, le discours du capitaliste, peuvent éclairer ce qui est à l’œuvre dans le processus de subjectivation de ces « enfants de la science » et les difficultés que cela suscite pour le psychanalyste quant à la direction de la cure avec l’enfant.
La fabrication de l'« autiste handicapé ». Chronique d'un passage à l'acte
Authors: Wacjman Claude , Douville Olivier 
Published: November 2012

Au moyen d’un choix de lectures théoriques, professionnelles et grand public et à travers l’examen des réactions de nos députés à la proposition de loi du 22 février 1996 (tendant à « assurer une prise en charge adaptée de l’autisme »), ce texte a pour objet de situer l’évolution du statut de l’autisme infantile en France et des politiques de soins dont il est l’objet. Et ce depuis quinze ans, c’est-à-dire depuis le moment où, par les avancées des lois de 1975, est posé avec davantage de netteté qu’il convient d’éviter la ségrégation scolaire. Nous posons la question : Que peut entraîner, sur les politiques et les pratiques de soin la reconnaissance légale de l’autisme comme handicap ?
