Lower extremity equipment-related injuries in alpine recreational skiers
Authors: Ekeland Arne , Holtmoen Age , Lystad Harald 
Published: June 2007

Lower extremity equipment-related injuries are the most significant injury group in alpine skiing. The lower extremity equipment-related injuries occurring at four Norwegian ski resorts were studied during the winter of 1985 to 1986. A total of 132 skiers with injuries were included (40% of all injured skiers) and compared with a randomly selected control population of 316 uninjured skiers. The most common lower extremity equipment- related injuries were knee sprains (56%) and lower leg fractures (14%), usually caused by no or late binding release. Significantly more lower extremity equipment-related injuries (33%) than other skiing injuries (19%) needed hospital admittance. Children below 10 years had a risk of lower leg fractures nine times that of skiers beyond 20 years. Beginners were six times more at risk for a lower extremity equipment-related injury than skiers of higher skiing abilities. The following factors were also associated with a significantly increased risk for a lower extremity equipment-related injury: less than three skiing seasons, no skiing instruction, and no self-testing of the bindings.
Spear tackler's spine
Authors: Torg Joseph S. , Sennett Brian , Pavlov Helene , Leventhal Marvin R. , Glasgow Steven G. 
Published: June 2007

We describe spear tackler's spine, a clinical entity that constitutes an absolute contraindication to participation in tackle football and other collision activities that ex pose the cervical spine to axial energy inputs. A subset of football players were identified who demonstrated: 1) developmental narrowing (stenosis) of the cervical canal; 2) persistent straightening or reversal of the normal cervical lordotic curve on erect lateral roentgen ograms obtained in the neutral position; 3) concomitant preexisting posttraumatic roentgenographic abnormal ities of the cervical spine; and 4) documentation of having employed spear tackling techniques. From data obtained by the National Football Head and Neck Injury Registry and the senior author's practice, 15 cases of spear tackler's spine were identified during 1987 to 1990. All 15 cases were evaluated because of complaints referable to the cervical spine or brachial plexus result ing from football injuries. Of these, 11 had complete neurologic recovery without permanent sequelae. Four cases resulted in permanent neurologic deficits: quad riplegia, 2; incomplete hemiplegia, 1; and residual long track signs, 1. Permanent neurologic injury occurred as the result of axial loading of a persistently straightened cervical spine from use of head-impact playing tech niques. We suggest that individuals who possess the aforementioned characteristics of spear tackler's spine be precluded from participation in collision activities that expose the cervical spine to axial energy inputs.
Arthroscopic transglenoid suture capsulolabral repairs: Preliminary results
Authors: Goldberg Bruce J. , Nirschl Robert P. , McConnell John P. , Pettrone Frank A. 
Published: June 2007

The arthroscopic transglenoid suture technique was performed on 38 shoulders for antenor capsulolabral repair or reconstruction. The primary complaint was instability in 34 shoulders (89%) and pain in 4 shoulders (11 %). In the instability subgroup, 3 (9%) experienced instability in their sleep, 17 (50%) with activities of daily living, and 14 (41 %) with athletic activities. Arthroscopic examination revealed labral detachment in 35 shoulders (92%) with additional capsular abnor malities noted in 17 (45%). The remaining 3 shoulders (8%) demonstrated capsular laxity and thinning without labral detachment. Twenty-nine shoulders had complete relief of insta bility. There were no redislocations. Four shoulders (10%) had recurrence of instability. Twenty shoulders (53%) obtained full range of motion, 15 (39%) had minor (<10°) loss of external rotation, 2 (5%) experienced greater (>10°) loss of external rotation, and 1 improved over a restricted preoperative range of motion. Fifteen of the 20 competitive athletes and 11 of the 15 recreational athletes returned to the same level and same type of athletic activity. Five patients did not resume their preinjury athletics because of unrelated life-style changes; they reported no shoulder problems. Four patients significantly reduced their athletic partic ipation because of postoperative instability or residual pain. In conclusion, relief of apprehension, reestablishment of shoulder stability and return to athletic activity, in cluding contact and throwing activities, can be achieved safely and effectively in appropriately selected patients.

Published: June 2007

We followed 292 patients who had sustained an acute traumatic hemarthrosis for a mean of 64 months. The KT-1000 arthrometer measurements within 90 days of injury revealed the injured knee was stable in 56 pa tients and unstable in 236. Forty-five unstable patients had an ACL reconstruction within 90 days of injury. Sur gical procedures performed >90 days after injury in cluded ligament reconstruction in 46 patients. Factors that correlated with patients who had late surgery for a meniscal tear or an ACL reconstruction ( P < 0.05) were preinjury hours of sports participation, arthrometer mea surements, and patient age. Follow-up data are presented for the patients divided into four groups: I, early stable, no reconstruction; II, early unstable, no reconstruction; III, early recon struction; and IV, late reconstruction. No patient changed occupation because of the knee injury. Hours per year of sports participation and levels of sports par ticipation decreased in all groups. Joint arthrosis was documented by radiograph and bone scan. Joint sur face injury abnormalities observed at surgery and me niscal surgery showed greater abnormalities by radio graph and bone scan scores ( P< 0.05). Reconstructed patients had a higher level of arthrosis by radiograph and bone scan.
Knee Extension and its Relationship to the Slope of the Intercondylar Roof
Authors: Howell Stephen M. , Barad Steven J. 
Published: June 2007

This study determined that knee extension (range, -30° to 2°) and the slope of the intercondylar roof (range, 26° to 46°) vary widely between knees in both men and women. We found a weak relationship between knee extension and the slope of the intercondylar roof (r2 = 0.207); therefore, roof angle cannot be predicted by clinically measuring knee extension. Clinical relevance: A knee with a given degree of ex tension can have a variety of different slopes to the in tercondylar roof. Knees with the combination of hyper extension and a vertically oriented slope to the intercondylar roof are "unforgiving" because they re quire a more posterior position for the tibial tunnel to avoid roof impingement and an extensive roofplasty. If the surgical objective is to minimize the extent of the roofplasty and avoid roof impingement, then consider ation should be given to customizing the placement of the tibial tunnel to account for variability in knee exten sion and roof angle when reconstructing the anterior cruciate ligament. Studies have shown that isometric graft placement can be achieved with this surgical approach.
Unstable Angina Pectoris: An Interventional Approach to Management
Authors: Johnson Eric , Ports Thomas 
Published: June 2007

The therapy of unstable angina has changed consider ably in the last 15 years. An improved understanding of the pathophysiology has led to many of the changes. Thrombus, platelet activation, progression of athero sclerosis, and coronary vasospasm all appear to have a role. Initial management in unstable angina should begin with aggressive medical therapy with nitrates, calcium antagonists, beta blockers, and aspirin. In patients who are refractory to aggressive medical management, early cardiac catheterization and coronary arteriography is in dicated. The literature appears to confirm that patients with unstable angina who are stabilized with aggressive medical therapy fare as well as those treated with emer gency bypass surgery. Percutaneous transluminal coro nary angioplasty (PTCA) is the treatment of choice in medically refractory unstable angina patients with single-vessel coronary disease. New approaches include culprit lesion angioplasty, thrombolytic therapy, coronary sinus retroperfusion, and new catheter-based revascularization methods such as intracoronary stents, laser methods and atherectomy. Culprit lesion angioplasty involves angioplasty of only the angina-producing artery in patients with multivessel coronary disease. Early data suggest that this may be an effective short-term alternative to multivessel PTCA or bypass surgery. Recent data also suggest a beneficial role for thrombolytic therapy and synchronized coronary si nus retroperfusion with arterial blood in patients with unstable angina. New catheter-based approaches are in the early stages of development, and their eventual role in the treatment of coronary artery disease and unstable angina remains to be elucidated.
Analytic Reviews : Organ Procurement and Brain Death in Trauma Patients
Authors: Mackersie Robert C. 
Published: June 2007

The success rates and effectiveness of transplantation programs continue to increase, as does the need for cadaveric organs. Increasing organ procurement is a worthwhile goal that can be fully justified on economic, humanistic, and ethical bases. Although a great deal of progress has been made in terms of public and political awareness of organ procurement problems, additional changes and further education will be necessary before the number of cadaveric organs that are needlessly wasted can be reduced. Management of patients with unsurvivable head in juries or patients who are candidates for organ donation is a complex task involving critical care management, the declaration of brain death, and the identification of, and request for, organ donation from next of kin. This process involves the coordinated efforts of neurosur geons, critical care specialists, social workers, and the transplant team coordinators in organ procurement pro grams. Patients are best managed in tertiary centers that have staffs with the expertise and interest in performing these tasks. The time to cardiac death in brain-dead pa tients is frequently short and is hastened by the develop ment of rapidly progressive derangements in gas ex change, fluid and electrolyte homeostasis, temperature regulation, coagulation, and cardiovascular function. Premature death under these circumstances continues to be a major reason for organ-procurement failure. Ag gressive monitoring and treatment of the multiple med ical problems encountered, however, may reduce the number of patients who die prematurely and thus in crease organ procurement rates.
Nurse Ministry the Nurse as Modern Day Shaman
Authors: Stohl Christina 
Published: June 2007

Nurses in frequent contact with persons experiencing severe stress in the form of hospitalization, disability or life threatening illness are likely to be faced with questions about the meaning of life and the nature of spirituality. Nurses who have not sought their own answers to such questions may be stimulated to do so as they are called upon to relate on a deeper level with patients. Holistic nurses are increasingly exploring and writing about spirituality as a significant factor in patient care. In so doing, nurses have the opportunity to broaden and deepen their own perspectives and experiences of spirituality which, in turn, may lead them to delve into a variety of spiritual or religious philosophies. This article proposes a concept of holistic nursing encompassing the spirituality of the nurse. Nurse ministry is the name given this model of practice. The activities of nurse ministers are discussed and ways of developing such a practice suggested.
A New Way of Analyzing Labour Market Flows Using Work History Data
Authors: Burchell Brendan 
Published: June 2007

The methodological component of this paper describes a novel way of analyzing work-history data, treating the job change as the unit of analysis rather than the individual or the job. After considering the theoretical and practical problems and advantages of such an approach, two examples are given of the ways in which this technique can be used in the investigation of macro-level and micro-level labour market phenomena concerning the way in which individuals move between jobs. First, the way in which the rate of promotions and involuntary demotions follows the national unemployment rate is demonstrated. In times of high unemployment involuntary transitions from better to worse-paid jobs become much more numerous, even when that transition is not accompanied by a spell of unemployment. Second, the way in which demotions (whether precipitated by domestic considerations or dismissals and redundancies) and promotions are associated with moves from larger to smaller establishments is investigated and discussed. The case of women moving to small establishments is particularly striking; small firms may provide flexible jobs which are more compatible with women's domestic roles, but at some cost in terms of pay.
Valence Competition in the Spatial Stochastic Model
Authors: Schofield Norman 
Published: June 2007

The mean voter theorem of the stochastic spatial electoral model provides no explanation as to why multi-party systems under proportional representation display such diversity. Here, we extend the spatial model to include valence. Valence may be either a stochastic variable describing the variation in popularity for each candidate in the electorate or, alternatively, it will be generated by activist coalitions responding to the willingness of the candidate to pursue the interests of the coalition. In a general model of multiple candidates (or political agents), the first- and second-order conditions for pure strategy Nash equilibria are developed. It is shown that rational candidates will balance the gradient of electoral pull against the gradients generated by contending activist coalitions. The resulting Nash equilibria will almost never be at the mean of the voter distribution.
The Pentecostal Significance of Numbers 11
Authors: Cotton Roger 
Published: June 2007

AbstractNumbers 11 describes a very significant interconnectedness of the Spirit of God and leadership/ministry of God's people and prophetic activity. This is established as the LORD answered the first great need of Moses in leading the people of Israel on the journey through the wilderness of the Promised Land with a special demonstration of his Spirit. The empowering of the 70 elders accompanied by a prophetic experience foreshadowed the Acts 2— Pentecost event. Therefore, Number 11 should be considered as the foundational Charismatic/Pentecostal passage in the Old Testament.
What Meaneth This? Pentecostals and Theological Inquiry
Authors: Coulter Dale 
Published: June 2007

AbstractThis article investigates what it means to maintain a Pentecostal theology by asking whether Pentecostals have any theological distinctives to offer, and, if so, how they may be identified. The first part begins with two recent approaches that seek to articulate what is theologically distinctive for Pentecostals through an appeal to spiritual experience. Following a critique of those approaches, the author proposes a constructive framework within which theological distinctives may emerge. The article concludes by applying the framework to the doctrine of scripture as a test case in order to determine what may be theologically distinct in the Pentecostal confession about that doctrine.
Toward a Theology of Pentecostal Preaching
Authors: Gordy John 
Published: June 2007

AbstractIn spite of the recent surge of scholarship within the Pentecostal community during the past two decades, only a scarce amount of research and critical reflection has been devoted to the area of Pentecostal preaching. This article seeks to address that void by exploring the uniqueness of Pentecostal preaching, its internal dynamics and parameters, and proposing a framework to construct a theology of Pentecostal preaching.
The Church and the Development of Doctrine
Authors: Chan Simon 
Published: June 2007

AbstractDoctrines are the authoritative teachings of the Church, yet the modern church is hampered by its inability to speak authoritatively even to its own members on matters of doctrine. One reason is that doctrines are widely perceived as archaic and fixed formulations with little significance for the present day. True doctrines, in fact, are constantly developing as the Church moves towards eschatological fulfillment. Yet for doctrines to develop properly there needs to be a proper ecclesiology. The Church is not an entity that God brought into being to return creation to its original purpose after the Fall; rather, the Church is prior to creation, chosen in Christ before the creation of the world (Eph. 1.4). It is a divine-humanity, ontologically linked to Christ the Head. It is the living Body of Christ, the totus Christus.Within the continuing life of prayer and worship, the Church’s doctrines are re-enacted, renewed and developed. These acts constitute the ecclesial experience or the living tradition. The living tradition is the transmission and development of the gospel of Jesus Christ in the on-going practices of the Church through the power of the Holy Spirit. The coming of the Spirit upon the Church at Pentecost is not just to enable the Church to preach the gospel but to constitute the Church as part of the gospel itself. That is to say, the gospel story includes the story of the Spirit in the Church. The third person of the Godhead is revealed as such in his special relation to the Church. The Church, therefore, could be called the ‘polity of the Spirit’, that is, the public square in which the Spirit is especially at work to bring God’s ultimate purpose to fulfillment. There is, therefore, no separation between ecclesiology and pneumatology. They are necessary for maintaining the living tradition and ensuring the healthy development of doctrine until the Church attains unity of the faith. Pentecostals who see the Pentecost event as the distinctive mark of their identity have a special role to play: by becoming more truly catholic in their ecclesiology, they become more truly Pentecostal. This accords well with their early ecumenical instinct.
Nourishment for our Journey: The Pentecostal Via Salutis and Sacramental Ordinances
Authors: Archer Kenneth 
Published: June 2007

AbstractSacramental ordinances are community acts of commitment ordained by Christ as means of grace with particular symbolic significance for our Pentecostal identity (story) and faith journey (via salutis). By locating the sacramental ordinances in the Pentecostal story, the sacramental ordinances take on a spiritual-metaphorical-narrative nature. The metaphorical and narrative nature of the sacraments gives the Holy Spirit opportunity to work redemptively in our lives by strengthening the community in her journey (via salutis) thus (re) shaping Pentecostal identity as the eschatological people of God.
Lipopolysaccharide-induced vacuoles in macrophages: Their origin is plasma membrane-derived organelles and endoplasmic reticulum, but not lysosomes
Authors: Yoshida Keiichiro , Ono Michio , Sawada Hajime 
Published: June 2007

Lipopolysaccharide (LPS) is one of the potent activators of macrophages. LPS was shown to induce cell spreading and large vacuoles in the cytoplasm of a macrophage-like cell line, JY3. These vacuoles were negative for acid phosphatase histochemistry and did not take up Lucifer yellow added to the medium. Latex beads were incorporated into cytoplasmic vesicles distinct from the vacuoles. These results indicated that the vacuoles are neither phagosomes nor lysosomes. DiIC18(3), a specific marker of endoplasmic reticulum (ER), stained the vacuoles intensely, and DiOC6(3) stained the vacuoles at a density similar to nuclear envelope, suggesting ER origin of their membrane. Glucose-6-phosphatase, however, was not detected histochemically. Vacuoles were also stained with wheat germ agglutinin-horseradish peroxidase (WGA-HRP) or WGA-biotin, suggesting that the vacuoles originated from plasma membrane-endosome-trans Golgi network-secretory granule pathway. Golgi markers, TPPase or BODIPY-ceramide were not localized to the vacuolar membrane. These results indicate that the vacuoles may have dual origins; ER and plasma membrane-derived organelles.
The Effect of Agmatine Administration on Ischemic-Reperfused Isolated Rat Heart

Published: June 2007

Background: The natural polyamine Agmatine (Ag) plays a significant role in protection of nerve cell ischemic injury. A previous report indicated that Ag given intraperitoneally to rats enhanced the recovery of the heart from ischemic injury. Based on this initial observation, a larger investigation was undertaken to explore a dose-response effect and possible mechanisms underlying the protective effects.Methods: Using the modified Langendorff model, 36 isolated hearts were divided into five groups: group 1, hearts receiving 100 μM/L Ag pre-ischemia (n=7); group 2, hearts receiving 100 μM/L Ag preand post-ischemia, (n=7); group 3, hearts receiving 250 μM/L Ag preischemia (n=7); group 4, hearts receiving 250 μM/L Ag preand postischemia (n=7); and group 5, hearts receiving Krebs-Hensleit solution served as control (n=8). The study design included 20 minutes of perfusion, 30 minutes of global ischemia, and 30 minutes of reperfusion.Results: After ischemia, group 2 developed higher left ventricular pressure P(max) (P<0.01), improved first-derivative of the rise (dP/dt max; P<0.02), and fall (dP/dt min; P<0.04) in left ventricular pressure, and the area calculated under the left-ventricle developed pressure curve (pressure-time integral; P<0.015), but coronary flow was not significantly increased (P=0.06) compared to the control group. Group 1 had improved diastolic recovery: dP/dt min (P<0.05) and coronary flow (P<0.03), compared with the control group. Group 3 had improved P(max) (P<0.01), dP/dt min (P<0.01), and coronary flow (P<0.02); group 4 had no improvement in all hemodynamic parameters.Conclusion: Low doses of Ag given preand post-ischemia, and high doses given only preischemia have favorable, protective effects on the hemodynamic recovery of isolated rat heart undergoing global ischemia and reperfusion.
