Lumbar spinal 'juxtaarticular' cyst in a Gordon setter

An 11-year-old Gordon setter bitch was presented with a history of progressive weakness in the right hind limb associated with pain in the lumbar spine. Neurological deficits consisted of ataxia, monoparesis, muscle atrophy and spontaneous over-knuckling of the affected limb. A large 'juxtaarticular' cyst located in a right dorsolateral position of the intervertebral foramen at L3-L4 was diagnosed by magnetic resonance imaging. The cyst was removed through a modified laminectomy. The dog recovered quickly and returned to the owners 4 days after surgery with slight neurological symptoms. During the follow-up examination 2 and 6 months later, the Setter showed normal gait and neurological examination.

Firing Up the Crucible with Senator Lee Metcalf & Governor Forrest Anderson -- Judge Gordon Bennett in “The Crucible of Change”

During the lead-up to Montana second progressive era, Lee Metcalf and Forrest Anderson, along with others, kept the progressive flame lit in Montana. Metcalf’s political history is replete with close electoral wins because of his commitment to progressive ideals when the times were not always politically favorable for that. As State Legislator, MT Supreme Court Justice, Congressman and eventually as US Senator, Lee won races by as little as 55 votes because he stuck to his guns as a progressive. In Forrest Anderson’s career as a County Attorney, State Legislator, MT Supreme Court Justice and 12 years as MT Attorney General he was respected as a pragmatic practitioner of politics. But during that entire career leading up to his election as Governor, Forrest Anderson was also a stalwart supporter of the progressive agenda exemplified by FDR and the New Deal, which brought folks out of the Great Depression that was brought on by the bad policies of the GOP and big business. As MT’s second progressive period began in 1965, the first important election was Senator Metcalf’s successful re-election battle in 1966 with the sitting MT Governor, Tim Babcock. And the progressive express was really ignited by the election of Forrest Anderson as Governor in 1968 after 16 years of Republican Governors in MT. Gordon Bennett played a rather unique role, being a confidant of Metcalf and Anderson, both who respected his wide and varied experience, his intellect, and his roots in progressivism beginning with his formative years in the Red Corner of NE Montana. Working with Senator Metcalf and his team, including Brit Englund, Vic Reinemer, Peggy McLaughlin, Betty Davis and Jack Condon among others, Bennett helped shape the progressive message both in Washington DC and MT. Progressive labor and farm organizations, part of the progressive coalition, benefitted from Bennett’s advice and counsel and aided the Senator in his career including the huge challenge of having a sitting popular governor run against him for the Senate in 1966. Metcalf’s noted intern program produced a cadre of progressive leaders in Montana over the years. Most notably, Ron Richards transitioned from Metcalf Intern to Executive Secretary of the Montana Democratic Party (MDP) and assisted, along with Bennett, in the 1966 Metcalf-Babcock race in a big way. As Executive Secretary Richards was critical to the success of the MDP as a platform for Forrest Anderson’s general election run and win in 1968. After Forrest’s gubernatorial election, Richards became Executive Assistant (now called Chief of Staff) for Governor Anderson and also for Governor Thomas Judge. The Metcalf progressive strain, exemplified by many including Richards and Bennett, permeated Democratic politics during the second progressive era. So, too, did the coalition that supported Metcalf and his policies. The progressivism of the period of “In the Crucible of Change” was fired up by Lee Metcalf, Forrest Anderson and their supporters and coalitions, and Gordon Bennett was in the center of all of that, helping fire up the crucible, setting the stage for many policy advancements in both Washington DC and Montana. Gordon Bennett’s important role in the 1966 re-election of Senator Lee Metcalf and the 1968 election of Governor Forrest Anderson, as well as his wide experience in government and politics of that time allows him to provide us with an insider’s personal perspective of those races and other events at the beginning of the period of progressive change being documented “In the Crucible of Change,” as well as his personal insights into the larger political/policy picture of Montana. Gordon Bennett, a major and formative player “In the Crucible of Change,” was born in the far northeast town of Scobey, MT in 1922. He attended school in Scobey through the eighth grade and graduated from Helena High School. After attending Carroll College for two years, he received his BA in economics from Carleton College in Northfield, MN. During a brief stint on the east coast, his daily reading of the New York Times (“best newspaper in the world at that time … and now”) inspired him to pursue a career in journalism. He received his MA in Journalism from the University of Missouri and entered the field. As a reporter for the Great Falls Tribune under the ownership and management of the Warden Family, he observed and competed with the rigid control of Montana’s press by the Anaconda Company (the Great Falls Tribune was the only large newspaper in Montana NOT owned by ACM). Following his intellectual curiosity and his philosophical bend, he attended a number of Farm-Labor Institutes which he credits with motivating him to pursue solutions to economic and social woes through the law. In 1956, at the age of 34, he received his Juris Doctorate degree from the Georgetown University Law Center in Washington, DC. Bennett’s varied career included eighteen years as a farmer, four years in the US Army during WWII (1942-46), two years as Assistant MT Attorney General (1957-59) with Forrest Anderson, three years in private practice in Glasgow (1959-61), two years as Associate Solicitor in the Department of Interior in Washington, DC (1961-62), and private law practice in Helena from 1962 to 1969. While in Helena he was an unsuccessful candidate for the Montana Supreme Court (1962) and cemented his previous relationships with Attorney General Forrest Anderson and US Senator Lee Metcalf. Bennett modestly refuses to accept the title of Campaign Manager for either Lee Metcalf (1966 re-election over the challenger, MT Republican Governor Tim Babcock) or Forrest Anderson (his 1968 election as Governor), saying that “they ran their campaigns … we were only there to help.” But he has been generally recognized as having filled that critical role in both of those critical elections. After Governor Anderson’s election in 1968, Bennett was appointed Director of the MT Unemployment Compensation Commission, a position from where he could be a close advisor and confidant of the new Governor. In 1971, Governor Anderson appointed him Judge in the most important jurisdiction in Montana, the 1st Judicial District in Helena, a position he held for seventeen years (1971-88). Upon stepping down from his judgeship, for twenty years (1988-2008) he was a law instructor, mediator and arbitrator. He currently resides in Helena with his wife, Norma Tirrell, former newspaper reporter and researcher/writer. Bennett has two adult children and four grandchildren.

Beliefs about back pain predict the recovery rate over 52 consecutive weeks

OBJECTIVES: This study examined the course of low-back pain over 52 weeks following current pain at baseline. Initial beliefs about the inevitability of the pain's negative consequences and fear avoidance beliefs were examined as potential risk factors for persistent low-back pain. METHODS: On a weekly basis over a period of one year, 264 participants reported both the intensity and frequency of their low-back pain and the degree to which it impaired their work performance. In a multilevel regression analysis, predictor variables included initial low-back pain intensity, age, gender, body mass index, anxiety/depression, participation in sport, heavy workload, time (1-52 weeks), and scores on the "back beliefs" and "fear-avoidance beliefs" questionnaires. RESULTS: The group mean values for both the intensity and frequency of weekly low-back pain, and the impairment of work performance due to such pain showed a recovery within the first 12 weeks. In a multilevel regression of 9497 weekly measurements, greater weekly low-back pain and impairment were predicted by higher levels of work-related fear avoidance beliefs. A significant interaction between time and the scores on both the work-related fear-avoidance and back beliefs questionnaires indicated faster recovery and pain relief over time in those who reported less fear-avoidance and fewer negative beliefs. CONCLUSIONS: Negative beliefs about the inevitability of adverse consequences of low-back pain and work-related, fear-avoidance beliefs are independent risk factors for poor recovery from low-back pain.

Effectiveness of a calcium sodium phosphosilicate-containing prophylaxis paste in reducing dentine hypersensitivity immediately and 4 weeks after a single application: a double-blind randomized controlled trial

AIMS The aim of this single-site, randomized, controlled, double-blind, 3-arm parallel study was to determine the effectiveness of a prophylaxis paste containing 15% calcium sodium phosphosilicate (CSPS; NovaMin(®) ) with and without fluoride in reducing dentine hypersensitivity immediately after a single application and 28 days following dental scaling and root planing. MATERIALS & METHODS Overall, 151 subjects were enrolled in this study. All subjects received a scaling and root planing procedure followed by a final prophylaxis step using one of three different prophylaxis pastes: Test-A (15% NovaMin(®) and NaF), Test-B (15% NovaMin(®) ) and a control. Dentine hypersensitivity was assessed by tactile stimulus (Yeaple Probe(®) ) and by air blast (Schiff scale) at baseline, immediately after and 28 days after a prophylaxis procedure. One hundred and forty-nine subjects completed the study. RESULTS Subjects having received the test prophylaxis pastes showed statistically lower (anova, p < 0.05) dentine hypersensitivity compared with the control group immediately after the prophylaxis procedure (Yeaple Probe(®) : Test-A = 20.9 ± 12.6, Test-B = 22.7 ± 12.9, Control=11.2 ± 3.1; Schiff score: Test-A = 1.1 ± 0.6, Test-B = 1.1 ± 0.6, Control = 2.0 ± 0.7) and after 28 days (Yeaple probe: Test-A = 21.5 ± 11.9, Test-B = 20.6 ± 11.3, Control = 11.8 ± 6.0; Schiff score: Test-A = 1.0 ± 0.6, Test-B = 1.0 ± 0.6, Control = 2.0 ± 0.7). CONCLUSIONS In conclusion, the single application of both fluoridated and non-fluoridated prophylaxis pastes containing 15% CSPS (NovaMin(®) ) provided a significant reduction of dentine hypersensitivity up to at least 28 days.

Relationship between depressive symptoms and acute low back pain at first medical consultation, three and six weeks of primary care

Background: Aim of the study was to test lagged reciprocal effects of depressive symptoms and acute low back pain (LBP) across the first weeks of primary care. Methods: In a prospective inception cohort study, 221 primary care patients with acute or subacute LBP were assessed at the time of initial consultation and then followed up at three and six weeks. Key measures were depressive symptoms (modified Zung Self-Rating Depression Scale) and LBP (sensory pain, present pain index and visual analogue scale of the Short-Form McGill Pain Questionnaire). Results: When only cross-lagged effects of six weeks were tested, a reciprocal positive relationship between LBP and depressive symptoms was shown in a cross-lagged structural equation model (β = .15 and .17, p < .01). When lagged reciprocal paths at three- and six-week follow-up were tested, depressive symptoms at the time of consultation predicted higher LBP severity after three weeks (β = .23, p < .01). LBP after three weeks had in turn a positive cross-lagged effect on depression after six weeks (β = .27, p < .001). Conclusions: Reciprocal effects of depressive symptoms and LBP seem to depend on time under medical treatment. Health practitioners should screen for and treat depressive symptoms at the first consultation to improve the LBP treatment.

Benzoxazinoid Metabolites Regulate Innate Immunity against Aphids and Fungi in Maize

Benzoxazinoids (BXs), such as 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxazin-3(4H)-one (DIMBOA), are secondary metabolites in grasses. The first step in BX biosynthesis converts indole-3-glycerol phosphate into indole. In maize (Zea mays), this reaction is catalyzed by either BENZOXAZINELESS1 (BX1) or INDOLE GLYCEROL PHOSPHATE LYASE (IGL). The Bx1 gene is under developmental control and is mainly responsible for BX production, whereas the Igl gene is inducible by stress signals, such as wounding, herbivory, or jasmonates. To determine the role of BXs in defense against aphids and fungi, we compared basal resistance between Bx1 wild-type and bx1 mutant lines in the igl mutant background, thereby preventing BX production from IGL. Compared to Bx1 wild-type plants, BX-deficient bx1 mutant plants allowed better development of the cereal aphid Rhopalosiphum padi, and were affected in penetration resistance against the fungus Setosphaeria turtica. At stages preceding major tissue disruption, R. padi and S. turtica elicited increased accumulation of DIMBOA-glucoside, DIMBOA, and 2-hydroxy-4,7-dimethoxy-1,4-benzoxazin-3-one-glucoside (HDMBOA-glc), which was most pronounced in apoplastic leaf extracts. Treatment with the defense elicitor chitosan similarly enhanced apoplastic accumulation of DIMBOA and HDMBOA-glc, but repressed transcription of genes controlling BX biosynthesis downstream of BX1. This repression was also obtained after treatment with the BX precursor indole and DIMBOA, but not with HDMBOA-glc. Furthermore, BX-deficient bx1 mutant lines deposited less chitosan-induced callose than Bx1 wild-type lines, whereas apoplast infiltration with DIMBOA, but not HDMBOA-glc, mimicked chitosan-induced callose. Hence, DIMBOA functions as a defense regulatory signal in maize innate immunity, which acts in addition to its well-characterized activity as a biocidal defense metabolite.
