BACKGROUND: Pregabalin may reduce postoperative pain and opioid use. Higher doses may be more effective, but may cause sedation and confusion. This prospective, randomized, blinded, placebo-controlled study tested the hypothesis that pregabalin reduces pain at 2 weeks after total knee arthroplasty, but increases drowsiness and confusion. METHODS: Patients (30 per group) received capsules containing pregabalin (0, 50, 100, or 150 mg); two capsules before surgery, one capsule twice a day until postoperative day (POD) 14, one on POD15, and one on POD16. Multimodal analgesia included femoral nerve block, epidural analgesia, oxycodone-paracetamol, and meloxicam. The primary outcome was pain with flexion …
Effect Of Bone Loss In Anterior Shoulder Instability, G. H. Garcia, J. N. Liu, D. M. Dines, J. S. Dines
Effect Of Bone Loss In Anterior Shoulder Instability, G. H. Garcia, J. N. Liu, D. M. Dines, J. S. Dines
Journal Articles
Anterior shoulder instability with bone loss can be a difficult problem to treat. It usually involves a component of either glenoid deficiency or a Hill-Sachs lesion. Recent data shows that soft tissue procedures alone are typically not adequate to provide stability to the shoulder. As such, numerous surgical procedures have been described to directly address these bony deficits. For glenoid defects, coracoid transfer and iliac crest bone block procedures are popular and effective. For humeral head defects, both remplissage and osteochondral allografts have decreased the rates of recurrent instability. Our review provides an overview of current literature addressing these treatment …

Comorbid Profile Rather Than Age Determines Hip Fracture Mortality In A Nonagenarian Population, A. Graver, S. Merwin, L. Collins, N. Kohn, A. Goldman
Journal Articles
BACKGROUND: In light of poor outcomes with nonoperative management of hip fractures, orthopedic surgeons are faced with difficult decisions about which patients are too ill or too old for surgical treatment. QUESTIONS/PURPOSES: This study sought to investigate if patients over 90 years had different preoperative laboratory, clinical, and injury characteristics than younger patients with the same injury. We compared our cohort with previously published data. We wished to identify if there were pre-injury risk factors associated with 30-day mortality, which could be modified to enhance postoperative outcomes. METHODS: This is a retrospective review of 198 operatively managed hip fractures in …

Shoulder Arthroplasty: Return To Sport, M. M. Khair, J. S. Dines, D. M. Dines
Journal Articles
CONTEXT: Increasingly, total shoulder arthroplasty is being performed not only to treat the pain associated with glenohumeral arthritis but also to return patients to the level of activity and function they enjoyed prior to the development of arthritis. While return to sport and activity have been studied in the total knee and total hip replacement literature, it is only relatively recently that the same focus has been placed on total shoulder replacements. EVIDENCE ACQUISITION: PubMed database from the years 2000 to 2014. All studies relevant to shoulder arthroplasty and return to sport were included in the review. STUDY DESIGN: Clinical …

Journal Articles
Background: Acute lung injury (ALI) is a significant source of morbidity and mortality in critically ill patients. Age is a major determinant of clinical outcome in ALI. The increased ALI-associated mortality in the older population suggests that there are age-dependent alterations in the responses to pulmonary challenge. The objective of this observational study was to evaluate age-dependent differences in the acute (within 6 hours) immunological and physiological responses of the heart and lung, to pulmonary challenge, that could result in increased severity. Methods: Male C57Bl/6 mice (young: 2-3 months, old: 18-20 months) were challenged intratracheally with cell wall components from …

Journal Articles
OBJECTIVES: Ultrasound (US) is often used for the work-up of testicular pathology. The findings may implicate on its management. However, there is only scant data on the correlation between US findings and testicular tumor type and size. Herein, we report on a multicenter study, analyzing these correlations. METHODS: The study included patients who underwent orchiectomy between 2000 and 2010. Their charts were reviewed for US echogeneity, lesion size, pathological dimensions, histology, and the presence of calcifications, fibrosis, necrosis and/or intraepithelial neoplasia. The incidence of these parameters in benign versus malignant lesions and seminomatous germ cell tumors (SGCT) versus nonseminomatous germ …

Approaching The Next Revolution? Evolutionary Integration Of Neural And Immune Pathogen Sensing And Response, K. J. Tracey
Approaching The Next Revolution? Evolutionary Integration Of Neural And Immune Pathogen Sensing And Response, K. J. Tracey
Journal Articles
Mammalian immunity evolved by the process of natural selection that produced differential survival and reproduction advantages through combinations of hereditary traits underlying the response to pathogens. Primitive animals sense the presence of microbial pathogens through recognition of pathogen-derived molecules in their rudimentary immune and nervous systems. No molecular biological mechanism assigns primacy of pathogen sensing mechanisms to immune cells over neurons. Rather, in animals as diverse as Caenorhabditis elegans to mammals, neural reflexes are activated by the presence of pathogens and transduce neural mechanisms that control the development of immunity. A coming revolution in immunological thinking will require immunologists to …

Patients surviving sepsis develop anemia but the molecular mechanism is unknown. Here we observed that mice surviving polymicrobial Gram-negative sepsis develop hypochromic, microcytic anemia with reticulocytosis. The bone marrow of sepsis survivors accumulates polychromatophilic and orthochromatic erythroblasts. Compensatory extramedullary erythropoiesis in the spleen is defective during terminal differentiation. Circulating TNF and IL-6 are elevated for five days after the onset of sepsis, and serum HMGB1 levels are increased from day seven until at least day 28. Administration of recombinant HMGB1 to healthy mice mediates anemia with extramedullary erythropoiesis and significantly elevated reticulocyte counts. Moreover, administration of anti-HMGB1 monoclonal antibodies after …

Journal Articles
Exposure to acute and chronic stressors sensitizes the proinflammatory response of microglia to a subsequent immune challenge. However, the proximal signal by which stressors prime microglia remains unclear. Here, high mobility group box-1 (HMGB-1) protein was explored as a potential mediator of stress-induced microglial priming and whether HMGB-1 does so via the nucleotide-binding domain, leucine-rich repeat, pyrin domain containing protein 3 (NLRP3) inflammasome. Exposure to 100 inescapable tail shocks (ISs) increased HMGB-1 and NLRP3 protein in the hippocampus and led isolated microglia to release HMGB-1 ex vivo. To determine whether HMGB-1 signaling is necessary for stress-induced sensitization of microglia, the …

A woman in her early 70s presented with chest pain, dyspnoea and diaphoresis 30 min after her husband expired in our hospital. Cardiac markers were elevated and there were acute changes in ECG suggestive for acute coronary syndrome. Echocardiogram showed apical akinesis, basal segment hyperkinesis with an ejection fraction of 30%. Cardiac catheterisation was performed showing non-obstructive coronary arteries, leading to the diagnosis of stress-induced cardiomyopathy. The patient improved with medical management. Repeat echocardiogram 2 months later showed resolution of heart failure with an ejection fraction of 65-70%.

Comparative Review Of The Treatment Methodologies Of Carotid Stenosis, C. Bae, M. Szuchmacher, J. B. Chang
Journal Articles
The treatment of carotid stenosis entails three methodologies, namely, medical management, carotid angioplasty and stenting (CAS), as well as carotid endarterectomy (CEA). The North American Symptomatic Carotid Endarterectomy Trial (NASCET) and European Carotid Surgery Trial (ECST) have shown that symptomatic carotid stenosis greater than 70% is best treated with CEA. In asymptomatic patients with carotid stenosis greater than 60%, CEA was more beneficial than treatment with aspirin alone according to the Asymptomatic Carotid Atherosclerosis (ACAS) and Asymptomatic Carotid Stenosis Trial (ACST) trials. When CAS is compared with CEA, the CREST resulted in similar rates of ipsilateral stroke and death rates …

Journal Articles
BACKGROUND AND OBJECTIVES: Within the past few years, there has been a push for an even more minimally invasive approach to biliary disease with the adoption of single-incision laparoscopic cholecystectomy. We sought to compare 4 individual surgeon experiences to define whether there exists a learning curve for performing single-incision laparoscopic cholecystectomy. METHODS: We performed a retrospective review 290 single-incision laparoscopic cholecystectomies performed by a group of general surgeons, with varying levels of experience and training, at 3 institutions between May 2008 and September 2010. The procedure times were recorded for each single-incision laparoscopic cholecystectomy, ordered chronologically for each surgeon, and …

Journal Articles
BACKGROUND: The Model for End-stage Liver Disease (MELD) has been used as a prognostic tool since 2002 to predict pre-transplant mortality. Increasing proportions of transplant candidates with higher MELD scores, combined with improvements in transplant outcomes, mandate the need to study surgical outcomes in patients with MELD scores of >/=40. METHODS: A retrospective longitudinal analysis of United Network for Organ Sharing (UNOS) data on all liver transplantations performed between February 2002 and June 2011 (n = 33 398) stratified by MELD score (/=40) was conducted. The primary outcomes of interest were short- and longterm graft and patient survival. A Kaplan-Meier …

Journal Articles
BACKGROUND: Renal injury caused by ischemia-reperfusion (I/R) often occurs after shock or transplantation. Growth arrest-specific protein 6 (Gas6) is a secreted protein that binds to the TAM-Tyro3, Axl, Mer-family tyrosine kinase receptors, which modulate the inflammatory response and activate cell survival pathways. We hypothesized that Gas6 could have a protective role in attenuating the severity of renal injury after I/R. MATERIALS AND METHODS: Adult mice were subjected to 45 min of bilateral renal ischemia. Recombinant mouse Gas6 (rmGas6, 5 mug per mouse) or normal saline (vehicle) was administered intraperitoneally 1 h before ischemia and all subjects were sacrificed at 23 …

Total colectomy with ileostomy placement is a treatment for patients with inflammatory bowel disease or familial adenomatous polyposis (FAP). A rare and late complication of this treatment is carcinoma arising at the ileostomy site. We describe two such cases: a 78-year-old male 30 years after subtotal colectomy and ileostomy for FAP, and an 85-year-old male 50 years after colectomy and ileostomy for ulcerative colitis. The long latency period between creation of the ileostomies and development of carcinoma suggests a chronic metaplasia due to an irritating/inflammatory causative factor. Surgical excision of the mass and relocation of the stoma is the mainstay …

The Role Of B-1 Cells In Inflammation, M. Aziz, N. E. Holodick, T. L. Rothstein, P. Wang
Journal Articles
B-1 lymphocytes exhibit unique phenotypic, ontogenic, and functional characteristics that differ from the conventional B-2 cells. B-1 cells spontaneously secrete germline-like, repertoire-skewed polyreactive natural antibody, which acts as a first line of defense by neutralizing a wide range of pathogens before launching of the adaptive immune response. Immunomodulatory molecules such as interleukin-10, adenosine, granulocyte-macrophage colony-stimulating factor, interleukin-3, and interleukin-35 are also produced by B-1 cells in the presence or absence of stimulation, which regulate acute and chronic inflammatory diseases. Considerable progress has been made during the past three decades since the discovery of B-1 cells, which has improved not only …

We have previously demonstrated the involvement of milk fat globule-epidermal growth factor-factor 8 (MFG-E8) in reducing neutrophil infiltration in a murine model of acute lung injury (ALI). In the present study, we aimed to delineate the mechanisms through which MFG-E8 attenuates neutrophil migration. Recombinant human MFG-E8 (rhMFG-E8) was expressed and purified in our facility. The human differentiated neutrophil cell line, dHL-60, was treated with rhMFG-E8 and cell migration assay was performed in a Boyden chamber using recombinant interleukin-8 (IL-8) as the chemoattractant. Surface CXCR2 and intracellular G protein-coupled receptor kinase 2 (GRK2) levels were evaluated by flow cytometry or western …

The mediators in activating neural stem cells during the regenerative process of neurogenesis following stroke have not been fully identified. Milk fat globule-EGF Factor VIII (MFGE8), a secreted glycoprotein serves several cellular functions by binding to its receptor, alpha(v)beta(3)-integrin. However, its role in regulating neural stem cells after stroke has not been determined yet. We therefore, aim to reveal whether MFG-E8 promotes neural stem cell proliferation and migration during stroke. Stroke was induced in wild-type (Wt) and MFG-E8-deficinet (Mfge8(-/-)) mice by transient middle cerebral artery occlusion (tMCAO). Commercially available recombinant mouse MFG-E8 (rmMFG-E8) was used for mechanistic assays in neural …
