Abstract
PURPOSE Several case series have been published exploring a variety of surgical treatments for osteochondritis dissecans (OCD) in patients 18 years and younger, but a systematic review is currently lacking. This systemic review identifies the various surgical techniques reported in the literature for treating OCD and assesses the effectiveness of these treatments based on functional outcomes and radiographic healing. METHODS A search of the EMBASE and MEDLINE databases was performed to identify clinical studies reporting outcomes of surgical management of OCD in the knee. A quality assessment of the included articles was conducted independently by 2 reviewers using a quality assessment tool developed by Yang et al. RESULTS A total of 25 papers including 470 patients aged ≤18 years (516 lesions) met the eligibility criteria and were reviewed. Surgical techniques for stable lesions included (arthroscopic and open) transarticular drilling, either alone (41%) or with bioabsorbable pin fixation (3%), extra-articular drilling (29%) and fixation with bioabsorbable screws (4%) or bone pegs (4%). For unstable lesions, surgical techniques included (arthroscopic and open) fixation with bioabsorbable pins (9%), metal screws (4%), bone pegs (4 %), osteochondral plugs (3%) or bioabsorbable screws (2%), as well as transarticular drilling with bioabsorbable pin fixation (3%) and drilling with metal screw fixation (2%). CONCLUSION The most common techniques were transarticular drilling for stable lesions and bioabsorbable pin fixation for unstable lesions. The key findings were that the vast majority of lesions healed postoperatively, regardless of technique, and that high-quality trials are required to more appropriately compare the effectiveness of techniques. LEVEL OF EVIDENCE Systematic review, Level IV.

Abstract
UNLABELLED Purpose : To model how patients' knee range of motion (ROM), pain, and self-reported lower-extremity (LE) functional status change over the first 26 weeks following anterior cruciate ligament (ACL) reconstruction and to estimate the test-retest reliability of these measurements. METHODS Patients were assessed weekly over 26 weeks following ACL reconstruction. Outcomes were knee ROM, LE functional status measured by the Lower Extremity Functional Scale (LEFS), and pain measured by the 4-item pain intensity measure (P4). A nonlinear model was applied to describe change for each outcome. Intra-class correlation coefficients and standard errors of measurement were applied to estimate test-retest reliability and minimal detectable change. RESULTS A nonlinear model provided the following model fit values (R(2)): P4=0.71, extension ROM=0.51, flexion ROM=0.99, LEFS=0.97. For pain and ROM, the limit values were reached by approximately 12 weeks after reconstruction; LEFS values continued to increase up to 26 weeks. Test-retest reliability coefficients varied from 0.85 to 0.95. CONCLUSIONS The greatest improvement occurred in the first 8 weeks after surgery. Recovery was nearly complete by 12 weeks with respect to pain and ROM, although LE functional status continued to improve throughout the study period. Scores on all measures demonstrated reliability, which supports their use with individual patients.

Abstract
Several case series have been published exploring the surgical management of osteochondritis dissecans (OCD) of the knee in pediatric patients. This systemic review was performed to identify the surgical indications for this condition. A search of the Embase and Ovid Medline databases was performed to identify clinical studies reporting outcomes of surgical management of OCD in the knee in this patient population. A quality assessment of the included articles was conducted independently by two reviewers using a quality assessment tool developed by Yang et al. A total of 25 articles met the eligibility criteria and were reviewed; 40% of studies did not clearly describe their surgical indications. The remainder of the studies had a failure of nonoperative management with or without the concomitant use of imaging as their indication for surgery, or used lesion stability itself as the indication for surgery. This review outlines several surgical indications presented in the literature for the treatment of OCD lesions of the knee in the pediatric population. The most common indication for surgery was a failure of a trial of nonoperative treatment with or without the concomitant use of serial imaging. Although the quality of the case series was high, inconsistencies in reporting radiographic and arthroscopic classification of the OCD lesion were common.

Abstract
The beauty to up quark coupling constant |V(ub)| can be extracted from B → ρ e+ ν(e) combined with the form factors for D → K* e+ ν(e) and B → V ℓ+ ℓ- and D → ρ e+ ν(e). Using the entire CLEO-c ψ(3770) → DD event sample, corresponding to an integrated luminosity of 818 pb(-1) and approximately 5.4×10(6) DD events, we measure the form factors for the decays D0 → ρ- e+ ν(e) and D+ → ρ0 e+ ν(e) for the first time and the branching fractions with improved precision. A four-dimensional unbinned maximum likelihood fit determines the form factor ratios to be V(0)/A1(0)=1.48±0.15±0.05 and A2(0)/A1(0)=0.83±0.11±0.04. Assuming Cabibbo-Kobayashi-Maskawa unitarity, the known D meson lifetimes, and our measured branching fractions we obtain the form factor normalizations A1(0), A2(0), and V(0). We also present a measurement of the branching fraction for D+ → ω e+ ν(e) with improved precision.

Abstract
BACKGROUND Thromboprophylaxis in arthroscopy is controversial. Recent literature has shown variable rates of deep vein thrombosis following routine arthroscopic knee surgery; however, it is unknown if current practice reflects the literature. We have conducted a cross sectional survey to provide insight into the practice patterns perceived risks, benefits and barrier in the use of thromboprophylaxis. MATERIALS AND METHODS A 19 item survey was created regarding surgeons' use of thromboprophylaxis in their patients undergoing routine knee arthroscopy. E-mail surveys were sent out to members of the Canadian Orthopaedic Association. RESULTS Seventy-seven responses were obtained; of which 58.2% (n=45) of surgeons stated that they had a clinical interest in sports medicine, and 37.3% (n=29) had completed a fellowship in sports medicine or arthroscopy. Fifty five surgeons (71.6%) performed more than 40 arthroscopies per year. Prolonged surgical time was the only risk factor that would significantly increase their use of prophylaxis. Practice patterns surrounding the use of thromboprophylaxis were otherwise quite variable. CONCLUSIONS Our survey reveals that opinions and practice patterns surrounding the use of thromboprophylaxis following routine knee arthroscopy are diverse. This survey points out the need for larger well designed studies for concise guidelines.

Abstract
A healthy meniscus is important for normal function of the knee. Numerous studies support that the repair of a torn meniscus is important to prevent degenerative changes in the knee. The ability to repair torn menisci is based on several factors including location, tear orientation, chronicity, and concomitant ligamentous knee injuries. In this systematic review, meniscal repair technology is evaluated. Specifically, the retear rates are compared between the arrow repair and the suture repair techniques. After searching three databases (PubMed, Cochrane Central Register of Controlled Trials, and Embase) and reviewing annual meeting abstracts from the American Orthopaedic Society for Sports Medicine (2005 to 2010), four studies (two observational and two randomized controlled trials) were selected for this systematic review. Due to the limited study number and variability between studies (study design, sample population, outcome measures, and surgical technique), a meta-analysis was not performed. The overall quality of the literature was poor and thus conclusions are limited. No clear superiority of one technique was determined by this review.

Abstract
Using 586 pb(-1) of e+ e- collision data at E(c.m.) = 4170 MeV, produced at the Cornell Electron Storage Ring collider and collected with the CLEO-c detector, we observe the process e+ e- → π+ π- h(c)(1P). We measure its cross section to be 15.6±2.3±1.9±3.0 pb, where the third error is due to the external uncertainty on the branching fraction of ψ(2S) → π0 h(c)(1P), which we use for normalization. We also find evidence for e+ e- → ηh(c)(1P) at 4170 MeV at the 3σ level and see hints of a rise in the e+ e- → π+ π- h(c)(1P) cross section at 4260 MeV.

Abstract
This lesson describes an unusual case of a man who was recently diagnosed with type 1 diabetes and who presented with severe orthostatic hypotension. As his diabetes was recent in onset, well controlled, and he had no other signs of microvascular disease, other causes of orthostatic hypotension were sought. His serum and cerebrospinal fluid were strongly positive for Borrelia burgdorferi IgG, suggesting a diagnosis of Lyme neuroborreliosis. Autonomic instability in Lyme, while rare, has been previously reported.

Abstract
The efficacy and safety of levetiracetam (LEV), administered for management of levodopa-induced dyskinesias (LID) in Parkinson's disease (PD), was examined using a multicenter, double-blind, placebo-controlled, parallel groups, crossover trial. Because of having a period effect, data after crossover point was excluded from analysis. Levodopa-treated PD participants with LID (n = 38) received LEV 500 mg/day, were assessed, titrated to 1,000 mg/day and reassessed, before and after crossover. The placebo group followed the same routine. Primary efficacy was defined from percent change in "On with LID" time from patient diaries. Secondary efficacy assessment used "On without LID," "Off" time, unified PD rating scale (UPDRS), clinical global impression (CGI), and Goetz dyskinesia scale after levodopa challenge. Safety measures were also performed. On with LID time decreased 37 minutes (95% confidence interval [CI] 0.59, 7.15; P = 0.02) at 500 mg/day, 7.85% 75 minutes (95% CI 3.3, 12.4; P = 0.002) at 1,000 mg/day. On without LID time increased by 46 minutes (95% CI -1.55, -0.03; P = 0.04) at 500 mg/day and 55 minutes (95% CI -10.39, -1.14; P = 0.018) at 1,000 mg/day. UPDRS 32 showed decreased dyskinesia duration mean change 0.35 (95% CI 0.09, 0.5; P = 0.009) at 1,000 mg/day. CGI showed LID decreased by 0.7 (95% CI 0.21, 1.18; P = 0.006) at 1,000 mg/day. Patient diaries and UPDRS show no increase in Off time. This exploratory trial provides evidence that LEV in 1,000 mg/day, slowly titrated, could be useful in improving LID as was assessed with patient diaries, UPDRS, and CGI scales, safely, with minimal side effects.

Abstract
The utilization of glucose, amino acids, fatty acids, bicarbonate, purines, and pyrimidines by the Reiter treponeme was studied by using carbon 14-labeled substrates. The distribution of carbon from the substrates into various cell components was determined. Radioactivity from labeled bicarbonate in the cellular protein was restricted to aspartic acid. The Reiter treponeme is capable of synthesizing glycine, serine, alanine, aspartic acid, glutamic acid, proline, and possibly ornithine. Phenylalanine, arginine, lysine, leucine, isoleucine, valine, threonine, and histidine do not appear to be synthesized by this treponeme. The Reiter treponeme cannot synthesize fatty acids, and thymine is not incorporated. Glucose is a major carbon and energy source. Arginine, histidine, serine, threonine, and glutamic acid are degraded by the Reiter treponeme and may serve as energy sources. It was calculated that exogenously supplied amino acids contribute 41 to 54% of the cellular material; fatty acids, 18%; and glucose, 28 to 43%.

Abstract
Neurosurgery has traditionally been regarded as a surgical speciality unsuitable for doctors in their first clinical year after graduation with limited prior experience of such patients. However, the advent of UK Modernising Medical Careers' Foundation Year training and the European Working Time Directive mean neurosurgery is now available as a clinical placement for newly qualified doctors. The authors describe the development of such a post, first implemented in August 2008, which both facilitated safe and effective care of neurosurgical patients and enabled the trainee to achieve many of the goals of UK Foundation training. Suggestions are made for the implementation of further similar posts.

Abstract
In the elderly, cerebellar lesions are commonly metastatic tumours with poor prognosis. We describe two octogenarians who presented with obstructive hydrocephalus, secondary to posterior fossa tumours that, on computed tomography, were thought to be cerebellar metastases. Both lesions were excised and the histology proved them to be cerebellar haemangioblastomas, primary benign tumours of the posterior fossa, which are rare in the elderly.
