    El foramen esternal es un defecto congénito de la osificación esternal. La importancia de su conocimiento, en el campo de la Antropología Forense, radica en la posibilidad de su confusión con un orificio por proyectil de arma de fuego. Presentamos un caso excepcional, en el que coexisten en el mismo esternón, un foramen esternal y un orificio por proyectil de arma de fuego. Las fotografias muestran las diferentes características de ambos orificios.Sternal foramen is a congenital defect of ste...

    Conclusiones: En nuestra experiencia, la utilización de doble mamaria no se acompañó de mayor incidencia de dehiscencia esternal, pero si con problemas de infección superficial de la herida, sobre todo en el grupo de pacientes mujeres, con insuficiencia renal y transfundidos en quirófano. Para mantener el beneficio de la doble mamaria en estos pacientes, deberíamos ser especialmente cuidadosos e implementar nuevas estrategias de cierre esternal.

  7. La inobservancia a las normas sociales: hendiduras a la ontología de la realidad social

    Full Text Available El presente estudio ofrece una interpretación de naturaleza ontológica a uno de los fenómenos más divulgados recientemente por los medios informativos de comunicación: la displicencia de los sujetos al seguimiento de normas sociales. El trabajo se centra, especialmente, en los casos en los que se asume que la indiferencia a las normas tiene como causa la condición del privilegiado social. Argumenta que la inobservancia a las normas, más que ser un asunto de desigualdad social, es la sintomatología de importantes hendiduras en la ontología de la realidad social. Así, tres partes conforman este trabajo. En la primera se describen algunos casos que, desde los medios de comunicación, se presentan como representativos en la inobservancia a las normas sociales, especialmente, aquellos que son interpretados como un asunto de abuso de privilegio social. En la segunda parte, a partir de algunos trabajos de John Austin, Ulises Moulines y Gottlob Frege, se presenta una concepción de normas sociales, y su valor para la construcción de la ontología social. En la tercera parte, desde la propuesta del filósofo John Searle, se describen algunos rasgos esenciales de la ontología de la realidad social. Se concluye que el no seguimiento de las normas sociales socava los modos de existencia de la realidad social, y que los casos interpretados por los medios de comunicación como asunto de desigualdad social, requieren una interpretación que tenga en cuenta la estructura de la realidad social. This study offers an ontological interpretation of one of the phenomenon reported the most by the informative media recently: the disobedience to social norms by people. The article is mainly focused on the cases in which it is assumed that the indifference towards the norms is caused by the condition of the socially privileged. It proposes that the disobedience to norms, more than being a matter of social inequality, is the symptomatology of important

    Full Text Available La inhibición del crecimiento y desarrollo resultante del tratamiento quirúrgico en pacientes con labio y paladar hendido es un tema ampliamente discutido en el mundo. De acuerdo a la literatura, la deficiencia de tejidos, probablemente debida al ancho y la posición del segmento alveolar en la hendidura, es una variable a considerar que afecta al crecimiento del maxilar, el cual también puede verse influido por la corrección quirúrgica del labio, la nariz y el paladar, por tejido cicatricial, los diferentes tipos de tratamiento quirúrgico, el tiempo de cirugía, la habilidad del cirujano y la ortopedia prequirúrgica. El propósito de este estudio es determinar la posible asociación entre la severidad de la hendidura y el crecimiento maxilar en niños con labio y paladar hendido unilateral no sindrómico nacidos en el año 2001 y atendidos en el Hospital Nacional de Niños "Dr. Carlos Sáenz Herrera", Caja Costarricense de Seguro Social de San José, Costa Rica. El estudio fue de tipo retrospectivo y descriptivo, basado en datos recopilados de registros médicos, modelo inicial de escayola del maxilar del niño recién nacido, radiografía cefalométrica y modelo actual del maxilar del niño a la edad de 5 años. La muestra de estudio comprendió 13 pacientes. La dimensión transversal del arco fue asimétrica en 12 casos, lo que indica alteración del crecimiento en esta dirección. Existe una correlación positiva estadísticamente significativa entre la longitud del arco y el ángulo SNA, indicando que a mayor longitud de arco, el ángulo SNA es mayor. El valor promedio de ANB tiene una desviación importante superior a 2. No existe relación entre la posición y longitud del arco maxilar (SNA, BaNA y ANS-PNS y la severidad de la hendidura. Esto significa, que el tejido cicatricial, el tipo de tratamiento quirúrgico, el tiempo de cirugía, el cirujano, la habilidad del cirujano y la ortopedia prequirúrgica, no influyen en la direcci

    Full Text Available Las hendiduras orofaciales son las malformaciones craneofaciales más frecuentes y menos entendidas, se han propuesto diversos modos de herencia, sobre lo cual lo más aceptado es la influencia de agentes ambientales y genéticos. Con respecto a los mecanismos de desarrollo asociados con la palatogénesis normal es claro que las interacciones
    entre epitelio y mesénquima son las más importantes pero existen factores extrínsecos que influyen considerablemente. Se han establecido dos grupos de genes involucrados en la regulación de dichas interacciones: factores de transcripción (Homeobox y genes implicados en vías de señalización (factores de crecimiento. De estos últimos se ha hecho énfasis en el factor de crecimiento tranformante beta-3 (TGFb3 y las proteínas morfogenéticas óseas (BMPs por las funciones que ejercen durante la palatogénesis relacionadas con adhesión epitelial y transformación epitelio-mesenquimal en el caso del primero y con proliferación mesenquimal por parte de la BMP-4.Orafacial clefts are the most frequent craneofacial malformations but the least understood; hereditary and environmental agents have been associated. Epithelia and mesenchymal interactions are important developmental mechanisms associated with normal palatogenesis as well as other extrinsic factors. Two groups of genes have been implicated in these interactions: transcription factors (homeobox and signalling associated genes. Among the last ones, transformant growth factor beta-3 (TGFβ3 and bone morphogenetic proteins (BMPs have been emphasysed because their relation with epithelia adhesion and epithelio-mesenchyma transformation and BMP- 4 on mesenchymal proliferation.

    Full Text Available Os autores relatam a ocorrência de lesão oculta da articulação manúbrio-esternal na avaliação inicial de um paciente com fratura da coluna torácica (T9. Foi diagnosticada fratura de T9 no paciente do sexo masculino de 37 anos de idade associada a déficit neurológico parcial. No atendimento inicial, as radiografias realizadas não demonstraram a lesão da articulação manúbrioesternal. Durante a reabilitação, após a estabilização cirúrgica da fratura da coluna torácica, subitamente o paciente sentiu dor intensa, acompanhada de deformidade ao nível do esterno, tendo sido diagnosticada luxação manúbrio-esternal nos exames de imagem. Devido à recidiva da luxação e de dor incapacitante, foi necessária a realização da redução aberta e fixação da articulação manúbrio-esternal. Na avaliação após 12 meses, o paciente apresentou recuperação completa da lesão neurológica, consolidação da artrodese do segmento vertebral T7-T11, e manutenção da redução da articulação manúbrio-esternal, que era assintomática durante a realização das atividades cotidianas.The authors report the occurrence of an occult manubriosternal joint injury in the initial evaluation on a patient with a thoracic spine fracture (T9. This T9 fracture was diagnosed in a 37-year-old man and was associated with a partial neurological deficit. At the initial evaluation, the radiographs produced did not show the manubriosternal joint injury. During rehabilitation, after surgical stabilization of the thoracic spine fracture, the patient suddenly felt an intense pain accompanied by deformation at the sternal level. From imaging examinations, manubriosternal dislocation was diagnosed. Because of recurrence of the dislocation and the incapacitating pain, open reduction and fixation of the manubriosternal joint had to be performed. At the 12-month follow-up, the patient presented complete recovery of the neurological lesion, consolidation of the

    Full Text Available BACKGROUND: Deep sternal wound infection and mediastinitis determine high in-hospital mortality. International studies show that these patients are also at increased cardiovascular mortality risk in long-term follow-up. However, data are scarce and there is no national data. OBJECTIVES: The aim of this study is to evaluate the mortality and incidence of cardiovascular events in long-term follow-up of patients suffering from deep sternal wound infection and mediastinitis. METHODS: Case-control study, matched by propensity score in a 1:1 proportion, in patients submitted to coronary artery bypass grafting between 2005 and 2008 at the Institute Dante Pazzanese of Cardiology (São Paulo, SP, Brazil. The primary outcome was death. As a secondary outcome, we analyzed the composite event of myocardial infarction, new revascularization, stroke or death. RESULTS: Of 1975 patients, 114 developed one of the infections. During the mean follow up of 3.6 years, deep sternal wound infection and mediastinitis increased the risk of death by 8.26 (95% CI 1.88-36.29, P = 0.005 and the incidence of combined end point by 2.61 (95% CI 1.2-5.69, P = 0.015. The Kaplan-Meier curves for both outcomes demonstrated that the greatest risk occurs in the first six months, followed by a period of stabilization and further increase in the incidence of events after 4 years of hospital discharge. The similarity between the curves of primary and secondary outcomes may be consequent to the predominance of death on the combined cardiovascular events. CONCLUSION: The presence of deep sternal wound infection or mediastinitis increased mortality in long-term follow-up in this sample of the Brazilian population according to the same pattern displayed by the developed countries.INTRODUÇÃO: A infecção esternal profunda e a mediastinite determinam elevada mortalidade intra-hospitalar.

    Full Text Available BACKGROUND: Sternal wound infection (SWI after coronary artery bypass graft (CABG surgery is a major complication. Identifying patients at risk of SWI is essential for the application of preventive measures. OBJECTIVE: To identify the pre- and intra-operative risk factors, apply the STS risk score and determine the correlation between the risk score and microorganisms isolated from surgical wounds in a Brazilian hospital. METHODS: This is a retrospective analysis of a database of all CABG surgeries performed in a single institution from 2006 to 2008. Chi-square analysis was used for categorical variables and Student's t-test was used for quantitative variables. Multivariate logistic regression model was used to identify independent risk factors for SWI. P 40 kg/m² (OR 6.27, 95%CI 2.53-15.48; P40 kg/m², number of affected coronary arteries and use of bilateral internal thoracic artery were associated with a higher risk of infection. The STS risk score can be successfully used and there was no correlation between microorganisms, the score and risk factors at our institution.FUNDAMENTO: A infecção de ferida operatória esternal após cirurgia de revascularização miocárdica (CRM é uma grave complicação.

    Full Text Available Total thyroidectomy is a surgery that removes all the thyroid tissue from the patient. The suspect of cancer in a thyroid nodule is the most frequent indication and it is presume when previous fine needle puncture is positive or a goiter has significant volume increase or symptomes. Less frequent indications are hyperthyroidism when it is refractory to treatment with Iodine 131 or it is contraindicated, and in cases of symptomatic thyroiditis. The thyroid gland has an important anatomic relation whith the inferior laryngeal nerve and the parathyroid glands, for this reason it is imperative to perform extremely meticulous dissection to recognize each one of these elements and ensure their preservation. It is also essential to maintain strict hemostasis, in order to avoid any postoperative bleeding that could lead to a suffocating neck hematoma, feared complication that represents a surgical emergency and endangers the patient’s life.It is essential to run a formal technique, without skipping steps, and maintain prudence and patience that should rule any surgical act.

    Abstract Rationale: Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Patients and Methods: Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien–Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. Diagnosis and Outcomes: The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450–540 minutes), the mean estimated blood loss was 266 mL (range 100–400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8–24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Lessons: Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy. PMID:28099344

  13. Totally optimal decision rules

    KAUST Repository

    Amin, Talha

    2017-11-22

    Optimality of decision rules (patterns) can be measured in many ways. One of these is referred to as length. Length signifies the number of terms in a decision rule and is optimally minimized. Another, coverage represents the width of a rule’s applicability and generality. As such, it is desirable to maximize coverage. A totally optimal decision rule is a decision rule that has the minimum possible length and the maximum possible coverage. This paper presents a method for determining the presence of totally optimal decision rules for “complete” decision tables (representations of total functions in which different variables can have domains of differing values). Depending on the cardinalities of the domains, we can either guarantee for each tuple of values of the function that totally optimal rules exist for each row of the table (as in the case of total Boolean functions where the cardinalities are equal to 2) or, for each row, we can find a tuple of values of the function for which totally optimal rules do not exist for this row.

    The total energy monitor (TE) is a thermal sensor that determines the total energy of each FEL pulse based on the temperature rise induced in a silicon wafer upon absorption of the FEL. The TE provides a destructive measurement of the FEL pulse energy in real-time on a pulse-by-pulse basis. As a thermal detector, the TE is expected to suffer least from ultra-fast non-linear effects and to be easy to calibrate. It will therefore primarily be used to cross-calibrate other detectors such as the Gas Detector or the Direct Imager during LCLS commissioning. This document describes the design of the TE and summarizes the considerations and calculations that have led to it. This document summarizes the physics behind the operation of the Total Energy Monitor at LCLS and derives associated engineering specifications.

    2001-01-01

    Ankle arthritis has traditionally been treated surgically with arthrodesis (fusion) after conservative measures have been exhausted. The success of joint arthroplasty in the knee, hip, and shoulder inspired many attempts over the past 30 years to construct a workable ankle prosthesis. The failures of first generation prostheses caused skepticism regarding the feasibility of total ankle arthroplasty (TAR), but the mistakes of the past have been transformed into improvements and modifications. Today's second generation total ankle designs show promise, and outcomes are encouraging. The Agility Ankle (DePuy, Warsaw, IN) designed by Dr. Frank Alvine is featured in this article. The method of implant and postoperative management are reviewed.

    Bert, Jack M; Hooper, Jessica; Moen, Sam

    2017-12-01

    Outpatient total joint arthroplasty (OTJA) allows for a safe, cost effective pathway for appropriately selected patients. With current pressures on arthroplasty surgeons and their associated institutions to reduce costs per episode of care, it is important to define the steps and challenges associated with establishing an outpatient arthroplasty program. Several studies have outlined techniques of selecting patients suitable for this type of postoperative pathway. With emerging concerns about patients who undergo outpatient arthroplasty being at increased risk of medical complications, which may lessen projected cost savings, it is important to identify value-based strategies to optimize patient recovery after OTJA. This article reviews digital techniques for patient selection and data collection, operating room efficiency systems, and provides a summary of methods to build and maintain value in outpatient total joint replacement within the framework of bundled payment reimbursement.

    2013-01-01

    Full Text Available Background: Primary total elbow arthroplasty (TEA is a challenging procedure for orthopedic surgeons. It is not performed as frequently as compared to hip or knee arthroplasty. The elbow is a nonweight-bearing joint; however, static loading can create forces up to three times the body weight and dynamic loading up to six times. For elderly patients with deformity and ankylosis of the elbow due to posttraumatic arthritis or rheumatoid arthritis or comminuted fracture distal humerus, arthroplasty is one of the option. The aim of this study is to analyze the role of primary total elbow arthroplasty in cases of crippling deformity of elbow. Materials and Methods: We analyzed 11 cases of TEA, between December 2002 and September 2012. There were 8 females and 3 males. The average age was 40 years (range 30-69 years. The indications for TEA were rheumatoid arthritis, comminuted fracture distal humerus with intraarticular extension, and posttraumatic bony ankylosis of elbow joint. The Baksi sloppy (semi constrained hinge elbow prosthesis was used. Clinico-radiological followup was done at 1 month, 3 months, 6 months, 1 year, and then yearly basis. Results: In the present study, average supination was 70° (range 60-80° and average pronation was 70° (range 60-80°. Average flexion was 135° (range 130-135°. However, in 5 cases, there was loss of 15 to 35° (average 25° of extension (45° out of 11 cases. The mean Mayo elbow performance score was 95.4 points (range 70-100. Arm length discrepancy was only in four patients which was 36% out of 11 cases. Clinico-radiologically all the elbows were stable except in one case and no immediate postoperative complication was noted. Radiolucency or loosening of ulnar stem was seen in 2 cases (18% out of 11 cases, in 1 case it was noted after 5 years and in another after 10 years. In second case, revision arthroplasty was done, in which only ulnar hinge section, hinge screw and lock screw with hexagonal head

    The total artificial heart (TAH) is a form of mechanical circulatory support in which the patient's native ventricles and valves are explanted and replaced by a pneumatically powered artificial heart. Currently, the TAH is approved for use in end-stage biventricular heart failure as a bridge to heart transplantation. However, with an increasing global burden of cardiovascular disease and congestive heart failure, the number of patients with end-stage heart failure awaiting heart transplantation now far exceeds the number of available hearts. As a result, the use of mechanical circulatory support, including the TAH and left ventricular assist device (LVAD), is growing exponentially. The LVAD is already widely used as destination therapy, and destination therapy for the TAH is under investigation. While most patients requiring mechanical circulatory support are effectively treated with LVADs, there is a subset of patients with concurrent right ventricular failure or major structural barriers to LVAD placement in whom TAH may be more appropriate. The history, indications, surgical implantation, post device management, outcomes, complications, and future direction of the TAH are discussed in this review.

  20. Total disc replacement.

    2014-02-01

    Total disc replacement (TDR) (partial disc replacement will not be described) has been used in the lumbar spine since the 1980s, and more recently in the cervical spine. Although the biomechanical concepts are the same and both are inserted through an anterior approach, lumbar TDR is conventionally indicated for chronic low back pain, whereas cervical TDR is used for soft discal hernia resulting in cervicobrachial neuralgia. The insertion technique must be rigorous, with precise centering in the disc space, taking account of vascular anatomy, which is more complex in the lumbar region, particularly proximally to L5-S1. All of the numerous studies, including prospective randomized comparative trials, have demonstrated non-inferiority to fusion, or even short-term superiority regarding speed of improvement. The main implant-related complication is bridging heterotopic ossification with resulting loss of range of motion and increased rates of adjacent segment degeneration, although with an incidence lower than after arthrodesis. A sufficiently long follow-up, which has not yet been reached, will be necessary to establish definitively an advantage for TDR, particularly in the cervical spine.

    2018-02-01

    In the United States, cervical total disk arthroplasty (TDA) is US Federal Drug Administration (FDA) approved for use in both 1 and 2-level constructions for cervical disk disease resulting in myelopathy and/or radiculopathy. TDA designs vary in form, function, material composition, and even performance in?vivo. However, the therapeutic goals are the same: to remove the painful degenerative/damaged elements of the intervertebral discoligamenous joint complex, to preserve or restore the natural range of spinal motion, and to mitigate stresses on adjacent spinal segments, thereby theoretically limiting adjacent segment disease (ASDis). Cervical vertebrae exhibit complex, coupled motions that can be difficult to artificially replicate. Commonly available TDA designs include ball-and-socket rotation-only prostheses, ball-and-trough rotation and anterior-posterior translational prostheses, as well as unconstrained elastomeric disks that can rotate and translate freely in all directions. Each design has its respective advantages and disadvantages. At this time, available clinical evidence does not favor 1 design philosophy over another. The superiority of cervical TDA over the gold-standard anterior cervical discectomy and fusion is a subject of great controversy. Although most studies agree that cervical TDA is at least as effective as anterior cervical discectomy and fusion at reducing or eliminating preoperative pain and neurological symptoms, the clinical benefits of motion preservation- that is, reduced incidence of ASDis-are far less clear. Several short-to-mid-term studies suggest that disk arthroplasty reduces the radiographic incidence of adjacent segment degeneration; however, the degree to which this is clinically significant is disputed. At this time, TDA has not been clearly demonstrated to reduce symptomatic?ASDis.

  2. Total Knee Replacement

    2005-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness, in terms of pain reduction and functional improvement, and costing of total knee replacement (TKR) for people with osteoarthritis for whom less invasive treatments (such as physiotherapy, analgesics, anti-inflammatory drugs, intra-articular steroids, hyaluronic acids, and arthroscopic surgery) have failed. Clinical Need Osteoarthritis affects an estimated 10% to 12% of Canadian adults. The therapeutic goals of osteoarthritis treatment are to improve joint mobility and reduce pain. Stepwise treatment options include exercise, weight loss, physiotherapy, analgesics, anti-inflammatory drugs, intra-articular steroids and hyaluronic acids, arthroscopic surgery, and, in severe cases, total joint replacement with follow-up rehabilitation. These treatments are delivered by a range of health care professionals, including physiotherapists, occupational therapists, family physicians, internists, rheumatologists, and orthopedic surgeons. TKR is an end-of-line treatment for patients with severe pain and functional limitations. More women than men undergo knee replacement, and most patients are between 55 and 84 years old. The Technology TKR is a surgical procedure in which an artificial joint or prosthesis replaces a damaged knee joint. The primary indication for TKR is pain, followed by functional limitation. Usually, a person’s daily activities must be substantially affected by pain and functional limitations for him or her to be considered a candidate for TKR. There are 3 different types of knee replacement prostheses. Non-constrained prostheses use the patient’s ligaments and muscles to provide the stability for the prosthesis. Semi-constrained prostheses provide some stability for the knee and do not rely entirely on the patient’s ligaments and muscles to provide the stability. Constrained prostheses are for patients whose ligaments and muscles are not able to provide stability for

The compounds were identified as C30H60O2, C32H64O2, C34H68O2 and C36H72O2 respectively. The presence of these compounds has been reported previously in different marine organisms as well as in marine samples. It is interesting that there were some variations in the number and nature of isomers of similar wax esters reported earlier. Long-chain wax esters are normally waxy in nature and their presence in fire coral plays a vital role in the nutrient transfer to the coral mass. They may also act as a protective coating of the nematocyst of dactylozooid. The coral species were also subjected to mild acidic hydrolysis, followed by neutralization and partitioning between water and ether. The organic phase was dried and purified by column chromatography and thin layer chromatography (TLC. Diphenylamine was revealed as the main product in one of the fractions. It is worth noting that diphenylamine is reported for the first time as a marine natural product. Diphenylamine is known to be toxic and causes allergic reactions to the skin, so it can be considered as responsible for the stinging property of fire coral.

    2017-07-01

    Total hip replacement is a salvage procedure that is done to alleviate discomfort secondary to osteoarthritis in the hip, which is most often a result of hip dysplasia. Commercially available total hip replacement implants for small animal patients are classified as cemented or cementless. The INNOPLANT Total Hip Replacement system includes modular, screw-in cementless components that were developed to improve implant stability by maintaining as much normal anatomic structure, and by extension biomechanics of the coxofemoral joint, as possible. As a newer system, there are few data and no long-term studies available in the veterinary literature. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available FIABA ONLUS (Italian Fund for Elimination of Architectural Barriers was founded in 2000 with the aim of promoting a culture of equal opportunities and, above all, it has as its main goal to involve public and private institutions to create a really accessible and usable environment for everyone. Total accessibility, Total usability and Total mobility are key indicators to define quality of life within cities. A supportive environment that is free of architectural, cultural and psychological barriers allows everyone to live with ease and universality. In fact, people who access to goods and services in the urban context can use to their advantage time and space, so they can do their activities and can maintain relationships that are deemed significant for their social life. The main aim of urban accessibility is to raise the comfort of space for citizens, eliminating all barriers that discriminate people, and prevent from an equality of opportunity. “FIABA FUND - City of ... for the removal of architectural barriers” is an idea of FIABA that has already affected many regions of Italy as Lazio, Lombardy, Campania, Abruzzi and Calabria. It is a National project which provides for opening a bank account in the cities of referring, in which for the first time, all together, individuals and private and public institutions can make a donation to fund initiatives for the removal of architectural barriers within its own territory for a real and effective total accessibility. Last February the fund was launched in Rome with the aim of achieving a Capital without barriers and a Town European model of accessibility and usability. Urban mobility is a prerequisite to access to goods and services, and to organize activities related to daily life. FIABA promotes the concept of sustainable mobility for all, supported by the European Commission’s White Paper.

    Collins, Justin W; Wiklund, N Peter

    2014-09-01

    We performed a systematic literature review to assess the current status of a totally intracorporeal robot-assisted radical cystectomy (RARC) approach. The current 'gold standard' for radical cystectomy remains open radical cystectomy. RARC has lagged behind robot-assisted prostatectomy in terms of adoption and perceived patient benefit, but there are indications that this is now changing. There have been several recently published large series of RARC, both with extracorporeal and with intracorporeal urinary diversions. The present review focuses on the totally intracorporeal approach. Radical cystectomy is complex surgery with several important outcome measures, including oncological and functional outcomes, complication rates, patient recovery and cost implications. We aim to answer the question of whether there are advantages to a totally intracorporeal robotic approach or whether we are simply making an already complex procedure more challenging with an associated increase in complication rates. We review the current status of both oncological and functional outcomes of totally intracorporeal RARC compared with standard RARC with extraperitoneal urinary diversion and with open radical cystectomy, and assess the associated short- and long-term complication rates. We also review aspects in training and research that have affected the uptake of RARC. Additionally we evaluate how current technology is contributing to the future development of this surgical technique. © 2013 The Authors. BJU International © 2013 BJU International.

    1984-08-01

    In the ill hospitalized patient with clinically relevant malnutrition, there is a measurable decrease in the ratio of the total body potassium to total body water (TBK/TBW) and a detectable increase in the ratio of total exchangeable sodium to total exchangeable potassium (Nae/Ke). To evaluate body composition analyses in anorexia nervosa patients with chronic uncomplicated semistarvation, TBK and TBW were measured by whole body K40 counting and deuterium oxide dilution in 10 females with stable anorexia nervosa and 10 age-matched female controls. The ratio of TBK/TBW was significantly (p less than 0.05) higher in anorexia nervosa patients than controls. The close inverse correlation found in published studies between TBK/TBW and Nae/Ke together with our results suggest that in anorexia nervosa, Nae/Ke may be low or normal. A decreased TBK/TBW is not a good indicator of malnutrition in the anorexia nervosa patient. The use of a decreased TBK/TBW ratio or an elevated Nae/Ke ratio as a definition of malnutrition may result in inappropriate nutritional management in the patient with severe nonstressed chronic semistarvation.

    Bonutti, Peter M; Mont, Michael A; McMahon, Margo; Ragland, Phillip S; Kester, Mark

    2004-01-01

    Currently, minimally invasive total knee arthroplasty is defined as an incision length of definition are: 1. The amount of soft-tissue dissection (including muscle, ligament, and capsular damage). 2. Patellar retraction or eversion. 3. Tibiofemoral dislocation. Minimally invasive surgery should not be considered to be a cosmetic procedure but rather one that addresses patients' concerns with regard to postoperative pain and slow rehabilitation. Standard total knee arthroplasties provide pain relief, but returning to activities of daily living remains a challenge for some individuals, who may take several weeks to recover. Several studies have demonstrated long-term success (at more than ten years) of standard total knee arthroplasties. However, many patients remain unsatisfied with the results of the surgery. In a study of functional limitations of patients with a Knee Society score of > or = 90 points after total knee arthroplasty, only 35% of patients stated that they had no limitations. This finding was highlighted in a study by Dickstein et al., in which one-third of the elderly patients who underwent knee replacement were unhappy with the outcome at six and twelve months postoperatively. Although many surgeons utilize objective functional scoring systems to evaluate outcome, it is likely that the criteria for a successful result of total knee arthroplasty differ between the patient and the surgeon. This was evident in a report by Bullens et al., who concluded that surgeons are more satisfied with the results of total knee arthroplasty than are their patients. Trousdale et al. showed that, in addition to concerns about long-term functional outcome, patients' major concerns were postoperative pain and the time required for recovery. Patients undergoing total knee arthroplasty have specific functional goals, such as climbing stairs, squatting, kneeling, and returning to some level of low-impact sports after surgery. Our clinical investigations demonstrated that

    Full Text Available Introduction: Routine hemithyroidectomy during total laryngectomy in the setting of advanced stage of laryngeal carcinoma without clear thyroid involvement remains a controversial issue. This study was conducted to assess the rate of thyroid gland involvement in the patients without obvious clinical involvement who were candidates for total laryngectomy. Materials and Methods: In this cross-sectional study, between 1994 and 2007, 186 patients who underwent total laryngectomy with ipsilateral hemithyroidectomy at Imam Khomeini hospital of Ahwaz Jondishapour university, were investigated for thyroid gland involvement. Results: Of 186 patients, 169 cases were men and 17 were women, with mean age of 63 years. Microscopic tissue study revealed tumor invasion to thyroid gland in 7 patients, all of them had clinically advanced disease. Among these patients, 5 cases had transglottic cancer and 2 cases had subglottic cancer. Moreover, 4 patients had thyroid cartilage invasion and in one patient pyriform sinus was involved. Conclusion: There may be no need for thyroidectomy in all total laryngectomy cases. We recommend hemithyroidectomy with isthmectomy during total laryngectomy only in cases with subglottic tumor extension, thyroid cartilage invasion, and pyriform sinus involvement.

    2008-01-01

    In recent years the analysis of the total scattering pattern has become an invaluable tool to study disordered crystalline and nanocrystalline materials. Traditional crystallographic structure determination is based on Bragg intensities and yields the long range average atomic structure. By including diffuse scattering into the analysis, the local and medium range atomic structure can be unravelled. Here we give an overview of recent experimental advances, using X-rays as well as neutron scattering as well as current trends in modelling of total scattering data.

    The correct prediction of total ozone as a function of latitude and season is extremely important for global models. This exercise tests the ability of a particular model to simulate ozone. The ozone production (P) and loss (L) will be specified from a well- established global model and will be used in all GCMs for subsequent prediction of ozone. This is the "B-3 Constrained Run" from M&MII. The exercise mostly tests a model stratospheric dynamics in the prediction of total ozone. The GCM predictions will be compared and contrasted with TOMS measurements.

    Background: Since first reported in 1996, endoscopic minimally invasive surgery of the cervical region has been shown to be safe and effective in the treatment of benign thyroid and parathyroid disease. The endoscopic transaxillary technique uses a remote lateral approach to the thyroid gland. Because of the perceived difficulty in accessing the contralateral anatomy of the thyroid gland, this technique has typically been reserved for patients with unilateral disease. Objectives: The present study examines the safety and feasibility of the transaxillary technique in dissecting and assessment of both thyroid lobes in performing near total thyroidectomy. Methods: Prior to this study we successfully performed endoscopic transaxillary thyroid lobectomy in 32 patients between August 2003 and August 2005. Technical feasibility in performing total thyroidectomy using this approach was accomplished first utilizing a porcine model followed by three human cadaver models prior to proceeding to human surgery. After IRB approval three female patients with histories of enlarging multinodular goiter were selected to undergo endoscopic near total thyroidectomy. Results: The average operative time for all models was 142 minutes (range 57–327 min). The three patients in this study had clinically enlarging multinodular goiters with an average size of 4 cm. The contralateral recurrent laryngeal nerve and parathyroid glands were identified in all cases. There was no post-operative bleeding, hoarseness or subcutaneous emphysema. Conclusion: Endoscopic transaxillary near total thyroidectomy is feasible and can be performed safely in human patients with bilateral thyroid disease. PMID:16882421

    Full Text Available Intrathoracic hernias after total gastrectomy are rare. We report the case of a 78-year-old man who underwent total gastrectomy with antecolic Roux-Y reconstruction for residual gastric cancer. He had alcoholic liver cirrhosis and received radical laparoscopic proximal gastrectomy for gastric cancer 3 years ago. Early gastric cancer in the remnant stomach was found by routine upper gastrointestinal endoscopy. We initially performed endoscopic submucosal dissection, but the vertical margin was positive in a pathological result. We performed total gastrectomy with antecolic Roux-Y reconstruction by laparotomy. For adhesion of the esophageal hiatus, the left chest was connected with the abdominal cavity. A pleural defect was not repaired. Two days after the operation, the patient was suspected of having intrathoracic hernia by chest X-rays. Computed tomography showed that the transverse colon and Roux limb were incarcerated in the left thoracic cavity. He was diagnosed with intrathoracic hernia, and emergency reduction and repair were performed. Operative findings showed that the Roux limb and transverse colon were incarcerated in the thoracic cavity. After reduction, the orifice of the hernia was closed by suturing the crus of the diaphragm with the ligament of the jejunum and omentum. After the second operation, he experienced anastomotic leakage and left pyothorax. Anastomotic leakage was improved with conservative therapy and he was discharged 76 days after the second operation.

    Ivancev, K.; Fork, T.; Haegerstrand, I.; Ivarsson, S.; Kullendorff, C.M.

    Two infants with total colonic aganglionosis (TCA) extending into the distal part of the ileum are described. Considerable diagnostic delay occurred with the correct diagnosis established first at 3 and 8 months, respectively. Radiologic findings compatible with TCA such as prolonged barium retention, reflux into ileum following barium enema, and foreshortening of colon were not clearly evident initially. Both patients demonstrated multiple acquired colon diverticula which increased both in number and size during the period of observation. These diverticula are probably a late manifestation of the spastic state of the anganglionic colon. Thus demonstration of diverticula supplies a strong evidence of TCA in infants with intestinal obstruction. (orig.).

    Total colonic is the most frequent form of extensive aganglionism. Diagnosis is difficult, but it must be taken in mind whenever either muscoviscidosis or ileal atresia are considered. Nine cases out of a series of 319 aganglionisms seen between 1957 and 1977 are reported. Ileostomy can be lifesaving but Duhamel-Lester Martin technique must be elected as a definitive treatment. The modification proposed by the authors, carried out in three cases, can be performed as a first-choice operation in the newborn. The long term results in these three cases are compared to those of other techniques. A general review of the problem is made.

    Orbay, Jorge L; Feliciano, Eric; Orbay, Carolina

    2012-11-01

    Total wrist arthrodesis is commonly performed using fixation plates, which can produce soft tissue irritation, often require removal, and limit the ability to position the hand in space. The Skeletal Dynamics IMPLATE is an intramedullary total wrist fusion device designed to provide stable fixation while avoiding the problems associated with plates. Radial and metacarpal locked intramedullary nails are inserted and joined by a connector. Desired hand placement is achieved by selecting the proper connector length and angle, then orienting it appropriately. Fusion mass compression is obtained by virtue of longitudinal threads on the radial nail that allow for length adjustment. Seven wrists in three men and four women were treated with this device and followed for a minimum of 24 weeks. In all cases, local cancellous bone graft was used and the third carpometacarpal (CMC) joint incorporated into the fusion. The median age was 49 (range, 28-71) years. Indications for fusion were two posttraumatic arthritides, three rheumatoid arthritides, one spastic deformity, and one infection. Patients were evaluated before surgery and at final follow-up using the Fernandez pain score and grip strength measurements using a hand-held dynamometer. All patients improved their grip strength and decreased their pain scores. All fusions united, and none of the patients presented dorsal soft tissue problems or required implant removal. One rheumatoid patient required secondary surgery for removal of a retained palmar osteophyte. This device delivers stable fixation, facilitates hand placement, and does not require removal.

    A prospective, multi-centre study was carried out on 1421 total hip replacements between January 1999 and July 2007 to examine if obesity has an effect on clinical outcomes. The patients were categorised into three groups: non-obese (body mass index (BMI) 40 kg/m(2)). The primary outcome measure was the change in Oxford hip score at five years. Secondary outcome measures included dislocation and revision rates, increased haemorrhage, deep infection, deep-vein thrombosis and pulmonary embolism, mean operating time and length of hospital stay. Radiological analysis assessing heterotopic ossification, femoral osteolysis and femoral stem positioning was performed. Data were incomplete for 362 hips (25.5%) There was no difference in the change in the Oxford hip score, complication rates or radiological changes at five years between the groups. The morbidly obese group was significantly younger and required a significantly longer operating time. Obese and morbidly obese patients have as much to gain from total hip replacement as non-obese patients.

    to determine the indications and to evaluate early and long-term outcomes of total pancreatectomy for pancreatic cancer. Treatment of 29 patients who underwent one- and two-stage pancreatectomy for different malignancies was analyzed. Median of surgery duration and intraoperative blood loss was 280 min and 2200 ml respectively. Postoperative complications were observed in 9 (31%) patients. There were 2 (6.9%) deaths. 1- and 3-year overall actual survival was 61% and 16% respectively in case of ductal adenocarcinoma. Median was 18 months. Patients after surgery for primary multiple lesion (cancer of pancreatic body-tail and major duodenal papilla), pancreatic metastases of renal cancer, mucinous cystadenoma and neuroendocrine cancer are still alive. Follow-up periods are 4, 49, 49 and 65 months respectively. Total pancreatectomy is difficult intervention followed by severe metabolic disorders. However it can improve long-term survival with acceptable incidence of postoperative complications and quality of life if clear indications for surgery are present.

  10. Qualidade total: Um novo paradigma?

    Full Text Available Nos últimos anos, o movimento para a implantação da Gestão da Qualidade Total vem crescendo ao redor do mundo. Em razão disso, há uma diversidade de ações realizadas com o nome de "Qualidade Total'. Uma revisão da teoria é complexa, porque existem muitos autores que tratam da questão. Eles escolhem diferentes perspectivas de análises (teóricas e empíricas e há dificuldades em se identificar um corpo conceitual. Há uma ampla difusão de modelos, ferramentas, técnicas, mercado e consultores. Essa popularidade, muitas vezes, faz com que determinadas organizações adotem essa forma de gestão do trabalho sem o conhecimento necessário das implicações que um modelo dessa ordem representa; especialmente no caso brasileiro, suscetível a proposições importadas. O presente artigo propõe um exame daquilo que os fundadores têm articulado sobre TQM, as principais críticas nesta direção e a avaliação de como vem sendo aplicadono nosso país.

  11. Total Value of Phosphorus Recovery.

    Phosphorus (P) is a critical, geographically concentrated, nonrenewable resource necessary to support global food production. In excess (e.g., due to runoff or wastewater discharges), P is also a primary cause of eutrophication. To reconcile the simultaneous shortage and overabundance of P, lost P flows must be recovered and reused, alongside improvements in P-use efficiency. While this motivation is increasingly being recognized, little P recovery is practiced today, as recovered P generally cannot compete with the relatively low cost of mined P. Therefore, P is often captured to prevent its release into the environment without beneficial recovery and reuse. However, additional incentives for P recovery emerge when accounting for the total value of P recovery. This article provides a comprehensive overview of the range of benefits of recovering P from waste streams, i.e., the total value of recovering P. This approach accounts for P products, as well as other assets that are associated with P and can be recovered in parallel, such as energy, nitrogen, metals and minerals, and water. Additionally, P recovery provides valuable services to society and the environment by protecting and improving environmental quality, enhancing efficiency of waste treatment facilities, and improving food security and social equity. The needs to make P recovery a reality are also discussed, including business models, bottlenecks, and policy and education strategies.

    Full Text Available The paper is devoted to testing electrooptical distance measuring devices (EDM built in total stations, than can be used for various tasks in the contemporary geodetic works. A rich market offer and availability of these universal measuring systems with satisfying distance range, excellent accuracy and other parameters, make total stations as dominant terrestrial geodetic instruments.For succesfully applying these instruments, above all for relliable distance measurements, the stability of the modulation frequency is the most important pre-condition. In the article, therefore, there are given some methods to verify the modulation frequency stability. In addition, some ways for determining the EDM distance constant and periodical corrections of the phase measuring unit are introduced for 4 types of EDM : LEICA 1700L, TOPCON GTS6A, TOPCON GTS2, C.ZEISS ELTA50. It were also investigated their possibilities for precise distance survey. Values of the determined constants and periodical corrections are presented in Tab. 2.Based on the investigation results of the 4 EDM types and using the values m obtained for different distances S, equations of the a posteriori standard deviations in form : m = (a+b.S were derived too.

    Jogging has been classified as a high-impact sport, and jogging after total hip arthroplasty (THA) has not been well documented. To investigate the participation rate for postoperative jogging as well as jogging parameters and the influence of jogging on implant stability and bearing wear. Case-control study; Level of evidence, 3. Included in this study were 804 hips in 608 patients (85 men, 523 women) who underwent THA between 2005 and 2011 with follow-up longer than 1 year. The mean patient age was 62 years (range, 26-98 years), and mean follow-up duration was 4.8 years (range, 2.3-7.8 years). Hip resurfacing arthroplasty (HRA) was performed in 81 patients and conventional THA in 527 patients. During routine postsurgical visits, patients were given a questionnaire concerning preoperative and postoperative jogging routines. For joggers, frequency, distance, duration, and velocity of jogging were recorded. Patients who did not jog postoperatively were asked to provide reasons for not jogging. Radiographs concerning implant migration and polyethylene wear were evaluated with specialized software, and serum cobalt and chromium ion concentrations were investigated for patients with metal-on-metal articulation. A total of 33 patients (5.4%) performed jogging preoperatively, and 23 patients (3.8%) performed jogging postoperatively. Of the 23 who jogged postoperatively, conventional THA was performed in 13 patients and HRA in 10 patients. Postoperatively, joggers trained a mean of 4 times (range, 1-7 times) per week, covering a mean distance of 3.6 km (range, 0.5-15 km) in a mean time of 29 minutes (range, 5-90 minutes) per session and at a mean speed of 7.7 km/h (range, 3-18 km/h). No patient complained of pain or showed serum cobalt and chromium ion elevation greater than 7 ppb. No hip showed loosening, abnormal component migration, or excessive wear at a mean 5-year follow-up. There were 74 postoperative non-joggers with an interest in jogging. The reasons given for

    One can no longer think about modern hernia surgery without mentioning endoscopic techniques. But due to their high technical demands the learning curve is comparatively long. And by technical mistakes and their consequences (pain, recurrence, complications) the benefits of the endoscopic techniques can easily be turned to drawbacks. The following text explains the steps of the total extraperitoneal endoscopic hernioplasty (TEP) technique in detail pointing out alternatives and risks. From preparation, indication and positioning, from trocar placement to extraperitoneal dissection and mesh placement, the principles of TEP are elucidated in respect of local anatomy and possible complications. The text as well as the accompanying video in the Mediathek are based on the authors' 20 years of experience in the TEP technique. Both of them may help in safe TEP application to minimise the complication rate as well as recurrences. Then patients can benefit from the advantages of this technique.

    A detailed description of our second-generation total synthesis of salinosporamide A is presented. Three contiguous stereocenters in the γ-lactam structure seen in the natural product were established by stereoselective functionalization of a D-arabinose scaffold, including an Overman rearrangement to generate a highly congested tetrasubstituted carbon center. One of the definitive reactions in the synthesis was a Lewis acid mediated skeletal rearrangement of a pyranose structure, which enabled the practical conversion of the carbohydrate scaffold to the γ-lactam structure embedded in salinosporamide A. The use of a benzyl ester as a protective group for a sterically hindered carboxylic acid led to a one-pot global deprotection at the end of the synthesis.

    Energy Technology Data Exchange (ETDEWEB)

    1993-12-01

    These Guidelines were designed by the Energy Quality Council to help managers and supervisors in the Department of Energy Complex bring Total Quality Management to their organizations. Because the Department is composed of a rich mixture of diverse organizations, each with its own distinctive culture and quality history, these Guidelines are intended to be adapted by users to meet the particular needs of their organizations. For example, for organizations that are well along on their quality journeys and may already have achieved quality results, these Guidelines will provide a consistent methodology and terminology reference to foster their alignment with the overall Energy quality initiative. For organizations that are just beginning their quality journeys, these Guidelines will serve as a startup manual on quality principles applied in the Energy context.

    As government funding grows scarce, competition between the national laboratories is increasing dramatically. In this era of tougher competition, there is no for resistance to change. There must instead be a uniform commitment to improving the overall quality of our products (research and technology) and an increased focus on our customers` needs. There has been an ongoing effort to bring the principles of total quality management (TQM) to all Energy Systems employees to help them better prepare for future changes while responding to the pressures on federal budgets. The need exists for instituting a vigorous program of education and training to an understanding of the techniques needed to improve and initiate a change in organizational culture. The TQM facilitator is responsible for educating the work force on the benefits of self-managed work teams, designing a program of instruction for implementation, and thus getting TQM off the ground at the worker and first-line supervisory levels so that the benefits can flow back up. This program plan presents a conceptual model for TQM in the form of a hot air balloon. In this model, there are numerous factors which can individually and collectively impede the progress of TQM within the division and the Laboratory. When these factors are addressed and corrected, the benefits of TQM become more visible. As this occurs, it is hoped that workers and management alike will grasp the ``total quality`` concept as an acceptable agent for change and continual improvement. TQM can then rise to the occasion and take its rightful place as an integral and valid step in the Laboratory`s formula for survival.

    Total pancreatectomy (TP) for pancreatic neoplasms is associated with high morbidity and mortality rates. However, with recent advances in surgical techniques and improved postoperative management, the number of cases with clinical indications for TP is increasing. Here, we evaluated the clinical outcomes post-TP. Patients (n = 41) who underwent TP between 2004 and 2011 at Tokyo Women's Medical University were retrospectively examined. Pre- and postoperative clinicophysiological data were collected up to 12 months post-TP and then analyzed. Only glycated hemoglobin (HbA1c), percentage of lymphocytes and hepatic Hounsfield unit level on computed tomography (CT) were significantly different between the preoperative state and at 12 months post-TP, while other clinicophysiological parameters remained unchanged. The quantity of the pancreatic enzyme administered significantly influenced glycemic control at 12 months post-TP (p < 0.05). All clinicophysiological parameters except for HbA1c were temporarily decreased after TP but normalized by 12 months. Thus, TP is a feasible surgical approach to treating pancreatic neoplasms with the potential to spread across the entire pancreas when adequately supplemented by synthetic insulin and pancreatic enzymes.

    We investigate the generalized gravitational entropy from total derivative terms in the gravitational action. Following the method of Lewkowycz and Maldacena, we find that the generalized gravitational entropy from total derivatives vanishes. We compare our results with the work of Astaneh, Patrushev, and Solodukhin. We find that if total derivatives produced nonzero entropy, the holographic and the field-theoretic universal terms of entanglement entropy would not match. Furthermore, the second law of thermodynamics could be violated if the entropy of total derivatives did not vanish.

  14. Operational resource theory of total quantum coherence

    Science.gov (United States)

    Yang, Si-ren; Yu, Chang-shui

    2018-01-01

    Quantum coherence is an essential feature of quantum mechanics and is an important physical resource in quantum information. Recently, the resource theory of quantum coherence has been established parallel with that of entanglement. In the resource theory, a resource can be well defined if given three ingredients: the free states, the resource, the (restricted) free operations. In this paper, we study the resource theory of coherence in a different light, that is, we consider the total coherence defined by the basis-free coherence maximized among all potential basis. We define the distillable total coherence and the total coherence cost and in both the asymptotic regime and the single-copy regime show the reversible transformation between a state with certain total coherence and the state with the unit reference total coherence. Extensively, we demonstrate that the total coherence can also be completely converted to the total correlation with the equal amount by the free operations. We also provide the alternative understanding of the total coherence, respectively, based on the entanglement and the total correlation in a different way.

  4. Totally optimal decision trees for Boolean functions

    KAUST Repository

    Chikalov, Igor

    2016-07-28

    We study decision trees which are totally optimal relative to different sets of complexity parameters for Boolean functions. A totally optimal tree is an optimal tree relative to each parameter from the set simultaneously. We consider the parameters characterizing both time (in the worst- and average-case) and space complexity of decision trees, i.e., depth, total path length (average depth), and number of nodes. We have created tools based on extensions of dynamic programming to study totally optimal trees. These tools are applicable to both exact and approximate decision trees, and allow us to make multi-stage optimization of decision trees relative to different parameters and to count the number of optimal trees. Based on the experimental results we have formulated the following hypotheses (and subsequently proved): for almost all Boolean functions there exist totally optimal decision trees (i) relative to the depth and number of nodes, and (ii) relative to the depth and average depth.

    Total remnant pancreatectomy after pancreaticoduodenectomy (PD) is a difficult procedure. Recently, distal pancreatectomy and PD have been performed laparoscopically. Herein, we present the first case report of a laparoscopic total remnant pancreatectomy. A 72-year-old woman underwent a totally laparoscopic pylorus-preserving PD for inferior bile duct cancer. The tumor was composed of moderately differentiated tubular adenocarcinoma and was diagnosed as pStage III according to the UICC-TNM classification. Eighteen months later, CT showed a low-density mass in the remnant pancreas. We conducted a total resection of the remnant pancreas laparoscopically. Histologically, it was diagnosed as a primary pancreatic cancer. The patient's postoperative course was uneventful. She was discharged on postoperative day 14. When an initial PD is performed laparoscopically, laparoscopic total remnant pancreatectomy is technically feasible and safe in selected patients. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

  11. Total lymphoid irradiation in alloimmunity and autoimmunity

    Energy Technology Data Exchange (ETDEWEB)

    Strober, S.

    1987-12-01

    Total lymphoid irradiation has been used as an immunosuppressive regimen in autoimmune disease and organ transplantation. The rationale for its use originated from studies of patients with Hodgkin disease, in whom this radiotherapy regimen was noted to induce profound and long-lasting immune suppression and yet was well tolerated, with few long-term side effects. Total lymphoid irradiation is a unique immunosuppressive regimen that produces a selective (and long-lasting) reduction in the number and function of helper T cells and certain subsets of B cells. Conventional immunosuppressive drugs show little selectivity, and their effects are short-lived. The most important aspect of total lymphoid irradiation is the potential for achieving transplantation tolerance and permanent remissions in autoimmune disease in laboratory animals. Attempts are being made to achieve similar goals in humans given total lymphoid irradiation, so that immunosuppressive drugs can be ultimately withdrawn from transplant recipients and patients with lupus nephritis. 28 references.

    2014-04-01

    Full Text Available Total Rewards Management is a subject of major importance for companies, because, by using models for this, firms can achieve their objectives of high performance. In order to analyse a validated total rewards model in Romanian Accounting and Consulting Companies, it is used The WorldatWork Total Rewards Model, which depict what contributes to applicant attraction and employee motivation and retention. Thus, the methodology of the previous survey is adjusted to the local context. The conclusions for the methodological aspects illustrate that the present research involves three strategic steps in order to achieve the objectives presented: the analysis of organizational environment of the companies from the sample, checking if Total Rewards Model proposed in the previous research is applicable for the same romanian companies from the previous survey, the analysing of the differences between results, and, if necessary, the adaptation of the model for Romania.

    The objective of this study was to measure and/or estimate the total antioxidant capacity of the Korean diet. Eighty-one plant foods that were expected to exhibit rather high antioxidant activities were selected from the Korean diet using the Fifth Korean National Health and Nutrition Survey (KNHANES V). These foods were categorized into 11 food groups: cereals, potatoes, legumes, nuts, vegetables, kimchies, mushrooms, fruits, fruit juices, sea weeds, and oils. The foods were mixed in the proportions specified in traditional Korean recipes and analyzed. The measured indicators for antioxidant capacities were total phenolics, 2,2-diphenyl-1-picrylhydrazyl (DPPH), oxygen radical absorbance capacity (ORAC), and Trolox equivalent antioxidant capacity (TEAC). Total phenolics were high in the fruit juices, nuts, vegetables, and fruits; and the average DPPH, ORAC, and TEAC values were high in the vegetables, fruits, fruit juices, and nuts. The correlation coefficient between the content of total phenolics of each food and the in vitro antioxidant capacity was relatively high at 0.851. The intake of total phenolics per capita per day in the Republic of Korea was estimated to be 127 mg. The total dietary antioxidant capacity (TDAC) values, which were obtained from the total antioxidant capacity of each food, taking into account the intake of each food, were 20,763, 54,335, and 876.4 µmol of Trolox equivalents using the DPPH, ORAC, and TEAC methods, respectively. The food group that contributed the most to the Korean TDAC was cereals at 39.7%, followed by fruits and vegetables at 27.8% and 13.9%, respectively. The contribution of legumes, nuts, fruit juices, and mushrooms was quite minimal at less than 2% each. The content of total phenolics and the antioxidant capacity of the Korean diet are significantly correlated and the high contributing food groups are cereals, fruits, and vegetables.

    1990-01-01

    Total lymphoid irradiation can prolong concordant cardiac xenografts. The effects of total lymphoid irradiation in a discordant xenograft model (guinea pig to rat) were studied with and without adjuvant pharmacologic immunosuppression. Inbred Lewis rats were randomly allocated to one of four groups. Group 1 (n = 6) served as a control group and rats received no immunosuppression. Group 2 (n = 5) received triple-drug therapy that consisted of intraperitoneal azathioprine (2 mg/kg), cyclosporine (20 mg/kg), and methylprednisolone (1 mg/kg) for 1 week before transplantation. Group 3 animals (n = 5) received 15 Gy of total lymphoid irradiation in 12 divided doses over a 3-week period. Group 4 (n = 6) received both triple-drug therapy and total lymphoid irradiation as described for groups 2 and 3. Complement-dependent cytotoxicity assay was performed to determine if a correlation between complement-dependent cytotoxicity and rejection-free interval existed. Rejection was defined as cessation of graft pulsation and was confirmed by histologic test results. Only groups 1 and 2 showed a difference in survival (group 1, 6.9 +/- 1.0 minutes; group 2, 14.2 +/- 2.7 minutes, p = 0.02). Although total lymphoid irradiation did decrease complement-dependent cytotoxicity, linear regression revealed no correlation between complement-dependent cytotoxicity and graft survival (coefficient of correlation, 0.30). Unlike concordant cardiac xenografts, total lymphoid irradiation with or without triple-drug therapy does not prolong graft survival.

  4. Signed Total Roman Edge Domination In Graphs

    2017-11-01

    Full Text Available Let G = (V,E be a simple graph with vertex set V and edge set E. A signed total Roman edge dominating function of G is a function f : Ʃ → {−1, 1, 2} satisfying the conditions that (i Ʃe′∈N(e f(e′ ≥ 1 for each e ∈ E, where N(e is the open neighborhood of e, and (ii every edge e for which f(e = −1 is adjacent to at least one edge e′ for which f(e′ = 2. The weight of a signed total Roman edge dominating function f is !(f = Ʃe∈E f(e. The signed total Roman edge domination number y′stR(G of G is the minimum weight of a signed total Roman edge dominating function of G. In this paper, we first prove that for every tree T of order n ≥ 4, y′stR(T ≥ 17−2n/5 and we characterize all extreme trees, and then we present some sharp bounds for the signed total Roman edge domination number. We also determine this parameter for some classes of graphs.

  5. Totally implantable catheter embolism: two related cases

    Directory of Open Access Journals (Sweden)

    Rodrigo Chaves Ribeiro

    Full Text Available CONTEXT AND OBJECTIVE: Long-term totally implantable catheters (e.g. Port-a-Cath® are frequently used for long-term venous access in children with cancer. The use of this type of catheter is associated with complications such as infection, extrusion, extravasation and thrombosis. Embolism of catheter fragments is a rare complication, but has potential for morbidity. The aim here was to report on two cases in which embolism of fragments of a long-term totally implantable catheter occurred. DESIGN AND SETTING: Case series study at Hospital do Servidor Público Estadual, São Paulo. METHODS: Retrospective review of catheter embolism in oncological pediatric patients with long-term totally implantable catheters. RESULTS: The first patient was a 3-year-old girl diagnosed with stage IV Wilms' tumor. Treatment was started with the introduction of a totally implantable catheter through the subclavian vein. At the time of removal, it was realized that the catheter had fractured inside the heart. An endovascular procedure was necessary to remove the fragment. The second case was a boy diagnosed with stage II Wilms' tumor at the age of two years. At the time of removal, it was noticed that the catheter had disconnected from the reservoir and an endovascular procedure was also necessary to remove the embolized catheter. CONCLUSION: Embolism of fragments of totally implantable catheters is a rare complication that needs to be recognized even in asymptomatic patients.

    This is the first report of fat embolism syndrome after bilateral total knee arthroplasty with the total condylar prosthesis. Cementing techniques and increased systemic monomer may play a role in the etiology of this syndrome. It is reasonable to suppose that fat embolism syndrome often occurs after total knee arthroplasty in an occult form.

    1989-01-01

    The incidence and location of heterotopic bone formation following total shoulder arthroplasty were evaluated in 58 Neer Mark-II total shoulder replacements. One year after surgery, 45% had developed some ectopic ossification. In six shoulders (10%) the ossifications roentgenographically bridged...... the glenohumeral and/or the glenoacromial space. There was no correlation between shoulder pain and the development of ossification. Shoulders with grade III heterotopic bone formation had a limited range of active elevation compared with shoulders without or with only a milder lesion. Men and patients...... with osteoarthritis of the shoulder joint were significantly disposed to the development of heterotopic bone. Heterotopic bone formation following total shoulder arthroplasty is frequent, but disabling heterotopic ossifications seem to be rare....

  8. Severe Heterotopic Ossification following Total Knee Replacement

    Directory of Open Access Journals (Sweden)

    Alexander L. Dodds

    2014-01-01

    Full Text Available Although the incidence of minor heterotopic ossification is probably higher than what is usually expected, severe heterotopic ossification (HO is an extremely rare event following total knee replacement surgery. We present the case of a 66-year-old woman who initially had achieved an excellent range of motion following bilateral uncemented rotating platform total knee replacement, before presenting with pain and loss of range of motion at 2 months after surgery. Severe HO was diagnosed on X-rays. Treatment consisted of nonoperative measures only, including physiotherapy with hydrotherapy and anti-inflammatories. She eventually regained her range of motion when seen at 8 months after operation. This case illustrates that nonoperative treatment without the use of radiotherapy or surgery can be used to safely resolve stiffness caused by HO after total knee replacement.

    Trache, Andreea; Meininger, Gerald A

    2008-08-01

    Total internal reflection fluorescence (TIRF) microscopy represents a method of exciting and visualizing fluorophores present in the near-membrane region of live or fixed cells grown on coverslips. TIRF microscopy is based on the total internal reflection phenomenon that occurs when light passes from a high-refractive medium (e.g., glass) into a low-refractive medium (e.g., cell, water). The evanescent field produced by total internally reflected light excites the fluorescent molecules at the cell-substrate interface and is accompanied by minimal exposure of the remaining cell volume. This technique provides high-contrast fluorescence images, with very low background and virtually no out-of-focus light, ideal for visualization and spectroscopy of single-molecule fluorescence near a surface. This unit presents, in a concise manner, the principle of operation, instrument diversity, and TIRF microscopy applications for the study of biological samples.

    Total hip arthroplasty (THA) is an effective and durable treatment option for hip osteoarthritis (OA). As life expectancy continues to increase, so too will the demand for joint arthroplasty in the 10th decade of life, frequently in cases involving osteoarthritis of both hips. Simultaneous bilateral total hip arthroplasty (SBTHA) is a valuable therapeutic option in appropriately selected patients with bilateral degenerative hip disease, although its use in the very elderly is poorly reported on in the literature. A case of bilateral hip OA successfully treated with SBTHA in a nonagenarian is presented and the literature is reviewed.

    2017-09-15

    The total synthesis of (±)-azaspirene (1) was achieved in a total of six steps from commercially available materials. Keys to the conciseness of our synthetic approach were the effective γ-lactam formation from linear precursor 36 and successful tandem epoxidations of γ-lactam 34 to afford α,β-epoxy-γ-hydroxy-γ-lactam intermediate 14. While our streamlined synthesis of azaspirene (1) sought inspiration from its biogenetic hypothesis, experimentally observed chemical reactivity of biosynthetically relevant precursors conversely provides insights to the biological origin of this natural product.

    Efforts to investigate both lyophilization and the measurement of colligative properties as an indication of total solute content are described. The objective of the work described is to develop a method for measuring total dissolved material in retort wastewaters which is simple and rugged enough to be performed in a field laboratory in support of pollution control tests. The analysis should also be rapid enough to provide timely and pertinent data to the pollution control plant operator. To be of most value, the technique developed also should be applicable to other synfuel wastewaters, most of which contain similar major components as oil shale retort waters. 4 references, 1 table.

    Sarmah, SS; Patel, S; Reading, G; El-Husseiny, M; Douglas, S; Haddad, FS

    2012-01-01

    INTRODUCTION The number of total knee arthroplasties performed continues to rise annually and it would be expected that complications, which include periprosthetic fractures, will also therefore become more commonplace. This article reviews the current literature regarding this injury and identifies the treatment principles that enable patients to regain optimal function. METHODS A comprehensive search of the Pubmed and Embase™ databases was performed to identify relevant articles. Keywords and MeSH (Medical Subject Headings) terms included in the search strategy were ‘periprosthetic fracture(s)’, ‘femur’, ‘tibia’, ‘patella(r)’, ‘complication(s)’, ‘failure(s)’, ‘risk(s)’, ‘prevalence’, ‘incidence’, ‘epidemiology’ and ‘classification(s)’. The search was limited to all articles published in English and reference lists from the original articles were reviewed to identify pertinent articles to include in this review. A total number of 43 studies were identified. RESULTS Common treatment aims have been identified when managing patients with a periprosthetic fracture around total knee arthoplasty. The main criterion that determines which option to choose is the degree of remaining bone stock and the amount of fracture displacement. CONCLUSIONS Treatment of a periprosthetic fracture around total knee arthroplasty will either be non-operative, osteosynthesis or revision arthroplasty. It is imperative that a suitable option is chosen and based on the published literature, pathways are outlined to aid the surgeon. PMID:22943223

    Obtaining primary wound healing in total joint arthroplasty is essential to a good result. Wound healing problems can occur and the consequences can be devastating. Determination of the host healing capacity can be useful in predicting complications. Cierney and Mader classified patients as type A, no healing compromises; and type B, systemic or local healing compromising factors present. Local factors include traumatic arthritis, multiple previous incisions, extensive scarring, lymphedema, poor vascular perfusion. Systemic compromising factors include diabetes, rheumatic diseases, renal or liver disease, immunocompromise, steroids, smoking, and poor nutrition. In high-risk patients, the surgeon should encourage positive choices such as smoking cessation and nutritional supplementation to elevate the total lymphocyte count and total albumin. Careful planning of incisions, particularly in patients with scarring or multiple previous operations, is productive. Around the knee the vascular viability is better in the medial flap. Thus, use the most lateral previous incision, do minimal undermining, and handle tissue meticulously. We perform all potentially complicated total knee arthroplasties without tourniquet to enhance blood flow and tissue viability. The use of perioperative anticoagulation will increase wound problems. If wound drainage or healing problems occur, immediate action is required. Deep sepsis can be ruled out with a joint aspiration and cell count (>2000), differential (>50% polys), and negative culture and sensitivity. All hematomas should be evacuated and necrosis or dehiscence should be managed by debridement to obtain a live wound. Copyright 2010, SLACK Incorporated.

    2016-09-01

    Total pancreatectomy is associated with short- and long-term high complication rate and without evidence of oncologic advantages. Several metabolic consequences are co-related with the apancreatic state. The unstable diabetes related to the total resection of the pancreas expose the patients to short- and long-term life-threatening complications. Severe hypoglycemia is a short-term dangerous complication that can also cause patients' death. Chronic complications of severe diabetes (cardiac and vascular diseases, neuropathy, nephropathy, and retinopathy) are also cause of morbidity, mortality and worsening of quality of life. For this reasons the number of total pancreatectomies performed has certainly decreased over time. However, today there are still some indications for this kind of procedures. Chronic pancreatitis untreatable with conventional treatments, surgical treatment of precancerous pancreatic lesions, surgical treatment of locally advanced pancreatic cancer and the management of patients with extraordinary high-risk pancreatic texture after pancreaticoduodenectomy represent possible indications for total pancreatectomy and are analyzed in the present paper.

    Implant functionality has clearly increased over the past decades because of improvements in total shoulder arthroplasty systems. This means that prostheses are now being implanted in younger patients with high sports activity. The implantation of the total shoulder arthroplasty does not mainly influence the sports activity. Case series; Level of evidence, 4. One hundred consecutive patients with unilateral total shoulder arthroplasty, followed for at least 1 year, were included in the study. Assessment preoperatively and 1 year and 2 years after operation included clinical examination and a validated questionnaire (Constant, Shoulder Pain and Disability Index [SPADI], and Disabilities of the Arm, Shoulder and Hand [DASH] scores, and the Short Form 36 [SF-36]). In addition, all patients received a sports questionnaire developed in house. Of the 55 patients who took part in sports before having shoulder disease, 49 (89%) were still able to participate after a mean follow-up of 2.8 years (range, 1.3-4.6 years). Seventeen patients had given up sports before total shoulder arthroplasty; 11 of them resumed activities after joint replacement but 6 did not start again. No patient had to stop sports because of the total shoulder arthroplasty. The sports most commonly mentioned were swimming (10 patients [20.4%]), golf (8 patients [16.3%]), cycling (8 patients [16.3%]), and fitness training (8 patients [16.3%]). Strength and range of motion, as well as the physical component summary (PCS) of the SF-36 and the Constant score (CS) after total shoulder arthroplasty, were significantly better in the sports group (49 of 100; PCS = 46, CS = 77) than in the nonsports group (45 of 100; PCS = 41,CS = 71). Eighteen patients (36.7%) stated that even after joint replacement, they still suffered restrictions on their sports activities because of shoulder problems. Whereas the overall mean age at follow-up was 68.9 years (range, 26-92 years), the mean age of patients participating in

On examination, visual acuity was 20/20 in each eye and left eye showed total ophthalmoplegia. Oral cavity revealed a hole in the left lateral part of the hard palate. We managed the case with tapering dose of systemic prednisolone. The total ophthalmoplegia was markedly improved in one month. Cases of foreign bodies in the orbit with intracranial extension are not unusual, but the path this foreign body traveled through the hard palate without affecting the optic nerve, internal carotid artery or cavernous sinus makes an interesting variation.

  1. A Modern Approach to Total Wellbeing

    Science.gov (United States)

    Hadzic, Maja; Chen, Meifania; Brouwer, Rick; Dillon, Tharam

    The events of the last decades have impacted our lives and our health significantly. We expected that the technology boom will improve our lives. While this may be true in a specific context, generally speaking our societies are suffering from moral decays, terrorism fears, wars, financial crisis and unpredictable acts of nature that are increasing in frequency and in intensity. The complex nature of the world we live is impacting our health and wellbeing considerably. Our health is not only determined by our physical health but is the end product of the interplay of the physical, mental, emotional, financial, relational and spiritual events of a lifetime. In this paper we develop a framework that will help us define and measure total wellbeing of individuals in our volatile societies. This framework will help us better understand the complex nature of total wellbeing and develop effective prevention and intervention strategies.

    © Springer International Publishing Switzerland 2015. The recently introduced second order total generalised variation functional TGV2 β,α has been a successful regulariser for image processing purposes. Its definition involves two positive parameters α and β whose values determine the amount and the quality of the regularisation. In this paper we report on the behaviour of TGV2 β,α in the cases where the parameters α, β as well as their ratio β/α becomes very large or very small. Among others, we prove that for sufficiently symmetric two dimensional data and large ratio β/α, TGV2 β,α regularisation coincides with total variation (TV) regularization

    ISO 15189:2012 requires the use of quality indicators (QIs) to monitor and evaluate all steps of the total testing process, but several difficulties dissuade laboratories from effective and continuous use of QIs in routine practice. An International Federation of Clinical Chemistry and Laboratory Medicine working group addressed this problem and implemented a project to develop a model of QIs to be used in clinical laboratories worldwide to monitor and evaluate all steps of the total testing process, and decrease error rates and improve patient services in laboratory testing. All laboratories are invited, at no cost, to enroll in the project and contribute to harmonized management at the international level. Copyright © 2016 Elsevier Inc. All rights reserved.

    Total elbow arthroplasty (TEA) is becoming a popular alternative to arthrodesis for patients with end-stage elbow arthrosis and comminuted distal humeral fractures. Prior outcome studies have primarily focused on surgical findings. Our purpose is to determine the radiographic outcome of TEA and to correlate with clinical symptoms such as pain. This is an IRB-approved retrospective review from 2005 to 2015 of all patients with semiconstrained TEA. All available elbow radiographs and clinical data were reviewed. Data analysis included descriptive statistics and Kaplan-Meier survival curves for radiographic and clinical survival. A total of 104 total elbow arthroplasties in 102 patients were reviewed; 75 % were in women and the mean patient age was 63.1 years. Mean radiographic follow-up was 826 days with average of four radiographs per patient. Seventy TEAs (67 %) developed radiographic complications, including heterotopic ossification (48 %), perihardware lucency (27 %), periprosthetic fracture (23 %), hardware subluxation/dislocation (7 %), polyethylene wear (3 %), and hardware fracture/dislodgement (3 %); 56 patients (55 %) developed symptoms of elbow pain or instability and 30 patients (30 %) underwent at least one reoperation. In patients with radiographic complications, 66 % developed elbow pain, compared to 19 % of patients with no radiologic complications (p = 0.001). Of the patients with radiographic complications, 39 % had at least one additional surgery compared to 0 % of patients without radiographic complications (p = 0.056). Radiographic complications are common in patients after total elbow arthroplasty. There is a strong positive association between post-operative radiographic findings and clinical outcome. Knowledge of common postoperative radiographic findings is important for the practicing radiologist. (orig.)

  11. Multi sensor reanalysis of total ozone

    Directory of Open Access Journals (Sweden)

    R. J. van der A

    2010-11-01

    Full Text Available A single coherent total ozone dataset, called the Multi Sensor Reanalysis (MSR, has been created from all available ozone column data measured by polar orbiting satellites in the near-ultraviolet Huggins band in the last thirty years. Fourteen total ozone satellite retrieval datasets from the instruments TOMS (on the satellites Nimbus-7 and Earth Probe, SBUV (Nimbus-7, NOAA-9, NOAA-11 and NOAA-16, GOME (ERS-2, SCIAMACHY (Envisat, OMI (EOS-Aura, and GOME-2 (Metop-A have been used in the MSR. As first step a bias correction scheme is applied to all satellite observations, based on independent ground-based total ozone data from the World Ozone and Ultraviolet Data Center. The correction is a function of solar zenith angle, viewing angle, time (trend, and effective ozone temperature. As second step data assimilation was applied to create a global dataset of total ozone analyses. The data assimilation method is a sub-optimal implementation of the Kalman filter technique, and is based on a chemical transport model driven by ECMWF meteorological fields. The chemical transport model provides a detailed description of (stratospheric transport and uses parameterisations for gas-phase and ozone hole chemistry. The MSR dataset results from a 30-year data assimilation run with the 14 corrected satellite datasets as input, and is available on a grid of 1× 1 1/2° with a sample frequency of 6 h for the complete time period (1978–2008. The Observation-minus-Analysis (OmA statistics show that the bias of the MSR analyses is less than 1% with an RMS standard deviation of about 2% as compared to the corrected satellite observations used.

    2010-01-01

    In May 2003, NASA's Short-term Prediction Research and Transition (SPoRT) program successfully provided total lightning data from the North Alabama Lightning Mapping Array (NALMA) to the National Weather Service (NWS) office in Huntsville, Alabama. The major accomplishment was providing the observations in real-time to the NWS in the native Advanced Weather Interactive Processing System (AWIPS) decision support system. Within days, the NALMA data were used to issue a tornado warning initiating seven years of ongoing support to the NWS' severe weather and situational awareness operations. With this success, SPoRT now provides real-time NALMA data to five forecast offices as well as working to transition data from total lightning networks at Kennedy Space Center and the White Sands Missile Range to the surrounding NWS offices. The only NALMA product that has been transitioned to SPoRT's partner NWS offices is the source density product, available at a 2 km resolution in 2 min intervals. However, discussions with users of total lightning data from other networks have shown that other products are available, ranging from spatial and temporal variations of the source density product to the creation of a flash extent density. SPoRT and the Huntsville, Alabama NWS are evaluating the utility of these variations as this has not been addressed since the initial transition in 2003. This preliminary analysis will focus on what products will best support the operational warning decision process. Data from 19 April 2009 are analyzed. On this day, severe thunderstorms formed ahead of an approaching cold front. Widespread severe weather was observed, primarily south of the Tennessee River with multiple, weak tornadoes, numerous severe hail reports, and wind. This preliminary analysis is the first step in evaluation which product(s) are best suited for operations. The ultimate goal is selecting a single product for use with all total lightning networks to streamline training and

    2015-06-01

    Two patients were successfully operated on for total scalp avulsions. Ages were between 11 and 35 years, and both patients were female. Bilateral temporal artery and veins were used as the recipient pedicles. Interpositional vein graft harvested from the left forearm was used in 1 patient. No nerve repair was performed. The scalp was successfully replanted in both cases. Venous congestion and arterial insufficiency were observed in 1 patient. Successful revision of the vascular anastomosis was performed. Total necrosis of the upper helical rim was observed in 1 patient. A mean size of 3 × 3 cm of tissue necrosis was observed in the occipital region of all patients. One patient was treated with split-thickness skin grafting, whereas the other one was left for secondary healing. The "replace like tissue with like tissue" represents the philosophy in replantation surgery. Although reconstructive surgeries imply advanced surgical methods, scalp replantation remains the only ideal surgical modality to create an embellishing natural-looking hair-bearing scalp. In this article, we present some tricks and pitfalls of total avulsed scalp replantation as well as our skills and literature review.

    Thoracic paravertebral block (TPVB) can be performed with or without general anaesthesia for various surgical procedures. TPVB is a popular anaesthetic technique due to its low side effect profile and high analgesic potency. We used 20 mL of 0.5% levobupivacaine for a single injection of unilateral TPVB at the T7 level with neurostimulator in a 63 year old patient with co-morbid disease who underwent cholecystectomy. Following the application patient lost consciousness, and was intubated. Haemodynamic instability was normalised with rapid volume replacement and vasopressors. Anaesthetic drugs were stopped at the end of the surgery and muscle relaxant was antagonised. Return of mucle strenght was shown with neuromuscular block monitoring. Approximately three hours after TPVB, spontaneous breathing started and consciousness returned. A total spinal block is a rare and life-threatening complication. A total spinal block is a complication of spinal anaesthesia, and it can also occur after peripheral blocks. Clinical presentation is characterised by hypotension, bradicardia, apnea, and cardiac arrest. An early diagnosis and appropriate treatment is life saving. In this case report, we want to present total spinal block after TPVB.

  18. Total Variation Depth for Functional Data

    KAUST Repository

    Huang, Huang

    2016-11-15

    There has been extensive work on data depth-based methods for robust multivariate data analysis. Recent developments have moved to infinite-dimensional objects such as functional data. In this work, we propose a new notion of depth, the total variation depth, for functional data. As a measure of depth, its properties are studied theoretically, and the associated outlier detection performance is investigated through simulations. Compared to magnitude outliers, shape outliers are often masked among the rest of samples and harder to identify. We show that the proposed total variation depth has many desirable features and is well suited for outlier detection. In particular, we propose to decompose the total variation depth into two components that are associated with shape and magnitude outlyingness, respectively. This decomposition allows us to develop an effective procedure for outlier detection and useful visualization tools, while naturally accounting for the correlation in functional data. Finally, the proposed methodology is demonstrated using real datasets of curves, images, and video frames.

    Severe storms often have high flash rates (in excess of one flash per second) and are dominated by intracloud lightning activity. In addition to the extraordinary flash rates, there is a second distinguishing lightning characteristic of severe storms that seems to be important. When the total lightning history is examined, one finds sudden increases in the lightning rate, which we refer to as lightning "jumps," that precede the occurrence of severe weather by ten or more minutes. These jumps are typically 30-60 flashes/min, and are easily identified as anomalously large derivatives in the flash rate. This relationship is associated with updraft intensification and updraft strength is an important factor in storm severity (through the accumulation of condensate aloft and the stretching of vorticity). In several cases, evidence for diminishment of midlevel rotation and the descent of angular momentum from aloft is present prior to the appearance of the surface tornado. Based on our experience with severe and tornadic storms in Central Florida, we believe the total lightning may augment the more traditional use of NEXRAD radars and storm spotters. However, a more rigorous relation of these jumps to storm kinematics is needed if we are to apply total lightning in a decision tree that leads to improved warning lead times and decreased false alarm rates.

    Malnutrition is reported to be an inevitable consequence of total gastrectomy, although there are few data to support this contention. Six patients of median age 63 years underwent total gastrectomy for malignancy. At follow-up (median 45 months, range 25-60 months) each patient was clinically tumour-free and underwent dietary assessment, faecal fat and nitrogen measurement and routine haematological testing. Protein and fat stores, measured by neutron activation analysis and the tritiated water dilution technique, were compared with the same measurements made before operation and with predicted values. Mean (s.d.) dietary intake (2224(381) kcal day-1 and 81(15)g protein day-1) met the patients' estimated requirements. Mean(s.d.) serum albumin and faecal nitrogen values were normal but there was notable steatorrhoea (21(17) g day-1). Body composition measurements revealed profound deficiencies of body-weight (P less than 0.02), protein (P less than 0.01) and fat (P less than 0.02) before operation which were not corrected by an apparently curative total gastrectomy (P less than 0.05), although further deterioration was prevented.

    Congestive hepatopathy (CH) and acute liver failure (ALF) are common among biventricular heart failure patients. We sought to evaluate the impact of total artificial heart (TAH) therapy on hepatic function and associated clinical outcomes. A total of 31 patients received a Syncardia Total Artificial Heart. Preoperatively 17 patients exhibited normal liver function or mild hepatic derangements that were clinically insignificant and did not qualify as acute or chronic liver failure, 5 patients exhibited ALF and 9 various hepatic derangements owing to CH. Liver associated mortality and postoperative course of liver values were prospectively documented and retrospectively analyzed. Liver associated mortality in normal liver function, ALF and CH cases was 0%, 20% (P=0.03) and 44.4% (P=0.0008) respectively. 1/17 (5.8%) patients with a normal liver function developed an ALF, 4/5 (80%) patients with an ALF experienced a markedly improvement of hepatic function and 6/9 (66.6%) patients with CH a significant deterioration. TAH therapy results in recovery of hepatic function in ALF cases. Patients with CH prior to surgery form a high risk group with increased liver associated mortality.

    Full Text Available Abstract Background Tashiromine 1 is a naturally occurring indolizidine alkaloid. It has been the subject of thirteen successful total syntheses to date. Our own approach centres on the stereoselective construction of the indolizidine core by capture of an electrophilic acyliminium species by a pendant allylsilane. The key cyclisation precursor is constructed using olefin cross-metathesis chemistry, which has the potential to facilitate both racemic and asymmetric approaches, depending upon the choice of the allylsilane metathesis partner. Results The use of the allyltrimethylsilane cross-metathesis approach enables the rapid construction of the key cyclisation precursor 3 (3 steps from commercial materials, which undergoes acid-induced cyclisation to give the desired bicyclic indolizidine skeleton as a 96:4 mixture of diastereomers. Simple functional group interconversions allowed the completion of the total synthesis of racemic tashiromine in six steps (19% overall yield. Three chiral α-alkoxyallylsilanes (12,14 and 15 were prepared in enantioenriched form and their cross-metathesis reactions studied as part of a putative asymmetric approach to tashiromine. In the event, α-hydroxysilane 12 underwent isomerisation under the reaction conditions to acylsilane 17, while silanes 14 and 15 were unreactive towards metathesis. Conclusion A concise, stereoselective total synthesis of racemic tashiromine has been developed. Attempts to translate this into an asymmetric synthesis have thus far been unsuccessful.

    Important chemical constituents analysis for the total flavone and total saponin in Gynostemma pentaphyllum is described. The colour reactions of flavones and saponines with vanillin-perchloric acid in acetic acid produced the good absorptions at 451 and 547 nm, but the absorption peaks too overlapped to be determined simultaneously. A new method for the total flavone and the total saponin in Gynostemma pentaphyllum to be determined by signal multiplier spectrophotometry simultaneously without any preliminary separation was proposed. For quantitative analysis, the rutinum as a standard of the total flavone and the ginsenoside Rb1 as standard of the total saponin were applied. The experiment results showed that the regression equations of concentration and deltaA were obtained: deltaAflavone = 0.0133+4.417 0Cflavone, relation coefficient rflavone = 0.9994, and the total flavone concentrations were in 0-0. 16 microg x mI(-1) with deltaA obeying linear relation; deltaAsaporin = 2.775 5Csaponin -0.8881 x 10(-2), relation coefficient rsaponin = 0.9991, and the total saponin concentrations were in 0-0.30 microg x mL(-1) with deltaA obeying linear relation respectively. The recovery ratio was 104.0%-113.0% and 86.8%-94.6% respectively. The RSDflavone was less than 0.58% (n = 9) and RSDsaponin was less than 0. 35% (n=9) respectively. The proposed method is simple, rapid accurate and feasible.

    The logic of total synthesis transformed a stagnant state of medicinal and synthetic organic chemistry when there was a paucity of methods and reagents to synthesize drug molecules and/or natural products. Molecular imaging by positron emission tomography (PET) is now experiencing a renaissance in the way radiopharmaceuticals for molecular imaging are synthesized, however, a paradigm shift is desperately needed in the discovery pipeline to accelerate in vivo imaging studies. A significant challenge in radiochemistry is the limited choice of labeled reagents (or building blocks) available for the synthesis of novel radiopharmaceuticals with the most commonly used short-lived radionuclides carbon-11 (11C; half-life ~20 minutes) and fluorine-18 (18F; half-life ~2 hours). In fact, most drugs cannot be labeled with 11C or 18F due to a lack of efficient and diverse radiosynthetic methods. In general, routine radiopharmaceutical production relies on the incorporation of the isotope at the last or penultimate step of synthesis, ideally within one half-life of the radionuclide, to maximize radiochemical yields and specific activities thereby reducing losses due to radioactive decay. Reliance on radiochemistry conducted within the constraints of an automated synthesis unit ("box") has stifled the exploration of multi-step reactions with short-lived radionuclides. Radiopharmaceutical synthesis can be transformed by considering logic of total synthesis to develop novel approaches for 11C- and 18F-radiolabeling complex molecules via retrosynthetic analysis and multi-step reactions. As a result of such exploration, new methods, reagents and radiopharmaceuticals for in vivo imaging studies are discovered. A new avenue to develop radiotracers that were previously unattainable due to the lack of efficient radiosynthetic methods is necessary to work towards our ultimate, albeit impossible goal - the concept we term total radiosynthesis - to radiolabel virtually any molecule.

    The paper presents influence of ceramic coating in all surfaces of the combustion chamber of SI four-stroke engine on working parameters mainly on heat balance and total efficiency. Three cases of engine were considered: standard without ceramic coating, fully adiabatic combustion chamber and engine with different thickness of ceramic coating. Consideration of adiabatic or semi-adiabatic engine was connected with mathematical modelling of heat transfer from the cylinder gas to the cooling medium. This model takes into account changeable convection coefficient based on the experimental formulas of Woschni, heat conductivity of multi-layer walls and also small effect of radiation in SI engines. The simulation model was elaborated with full heat transfer to the cooling medium and unsteady gas flow in the engine intake and exhaust systems. The computer program taking into account 0D model of engine processes in the cylinder and 1D model of gas flow was elaborated for determination of many basic engine thermodynamic parameters for Suzuki DR-Z400S 400 cc SI engine. The paper presents calculation results of influence of the ceramic coating thickness on indicated pressure, specific fuel consumption, cooling and exhaust heat losses. Next it were presented comparisons of effective power, heat losses in the cooling and exhaust systems, total efficiency in function of engine rotational speed and also comparison of temperature inside the cylinder for standard, semi-adiabatic and full adiabatic engine. On the basis of the achieved results it was found higher total efficiency of adiabatic engines at 2500 rpm from 27% for standard engine to 37% for full adiabatic engine.

    2009-01-01

    Background and purpose We have previously reported that the first 10 years of hip arthroplasty in Lithuania resulted in a higher cumulative revision rate than that observed in Sweden. We thus compared the corresponding results after introduaction of total knee replacement in Lithuania. Methods The 10-year revision rate for the first 595 primary ScanKnee arthroplasties inserted in Klaipeda, Lithuania, was compared to that for the first 1,280 ScanKnee primary arthroplasties inserted in Sweden. As in the hip replacement study, only patients with osteoarthritis (OA) were included. Primary knee arthroplasties without patellar resurfacing were included, and the endpoint was revision for any reason other than addition of a patellar component. Results We found that the cumulative revision rate was not statistically significantly different between the groups. The revision pattern was different, however, and we observed 24 isolated patellar component additions in Sweden, but none in Klaipeda. Interpretation Contrary to the results of our previous hip arthroplasty study, the cumulative revision rate after total knee arthroplasty was similar in the two groups. This suggests that compared to hip arthroplasty, the outcome of total knee arthroplasty was less dependent on surgical experience. The large difference regarding isolated patellar component additions may be explained by long-term accumulation of severe OA cases in Lithuania. To patients subject to a newly introduced surgical treatment offering great improvement in quality of life, patellofemoral pain may be a minor problem. Furthermore, patellar problems may not have seemed particularly relevant for the surgeons, considering the disability of other patients waiting to be treated. PMID:19297790

    2014-03-01

    Total shoulder arthroplasty is now capable of recreating near anatomic reproduction of native bony shoulder anatomy, but the function and longevity of anatomic shoulder replacement is dependent on a competent soft tissue envelope and adequate motoring of all musculo-tendinous units about the shoulder. Balancing the soft tissues requires understanding of the anatomy and pathology, as well as technical skills. The advent of reverse shoulder biomechanics has brought with it special requirements of understanding of the soft tissue elements still left in the shoulder despite major rotator cuff deficiency.

    The stability of somatostatin, added to a total parenteral nutrition formula, in glass containers and in plastic ethylene vinyl acetate containers was investigated. The somatostatin concentration decreased immediately from 3 micrograms/ml to 0.3-0.6 micrograms/ml after addition to the emulsion. In spite of this rapid decrease, somatostatin concentrations remained stable with values of 0.4-0.7 micrograms/ml during the follow-up period (24 h). These findings could be explained assuming adsorption to the surface of the container.

    Full Text Available This article is about two patients having vascular injuries complicating total hip arthroplasty because of intraoperative indirect injuries. One patient had a delayed presentation of acute lower limb ischaemia, in which he required amputation of his left second toe because of ischaemic gangrene. The other patient had acute lower limb ischaemia leading to permanent muscle and nerve damage because of delayed recognition. Both patients had vascular interventions for the indirect vascular injuries. Preoperative workup for suspicious underlying peripheral vascular disease, intraoperative precautions, and perioperative period of vascular status monitoring are essential for prevention and early detection of such sinister events.

    With advances in implant technology, total ankle arthroplasty (TAA) has become an increasingly popular alternative to arthrodesis for the management of end-stage ankle arthritis. However, reports in the literature do not focus on the imaging features of TAA. Through a literature review, we demonstrate basic design features of the current ankle arthroplasty system, and the normal and abnormal postoperative imaging features associated with such devices. Pre- and postoperative evaluations of ankle arthroplasty mainly include radiography; in addition, computed tomography and magnetic resonance imaging provide further characterization of imaging abnormalities. Familiarization with multimodal imaging features of frequent procedural complications at various postoperative intervals is important in radiological practice.

    Although the health benefits of vegetarian diets have been well documented among Western population, there are geographic differences of vegetarian diets and the health benefits of the Taiwanese vegetarian diet have not been studied extensively. In addition to conventional risk factors, homocysteine and high-sensitivity C-reactive protein (hs-CRP) levels have been found to predict first atherothrombotic events. We undertook this study to examine the total risk profile of Taiwanese vegetarians. A total of 198 healthy subjects (99 vegetarians and 99 omnivores) were recruited. Fasting blood samples were analyzed for glucose, cholesterol, triglyceride, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), white blood cell count, hs-CRP and homocysteine. There was no significant difference in age, body mass index, blood glucose, white blood cell count, triglyceride and HDL-C between the two groups. The vegetarian group had significantly more females (65.7 vs 46.5%); lower body weight (58.66+/-11.13 vs 62.88+/-12.24 kg); shorter height (159.14+/-7.88 vs 162.53 +/-8.14 cm); lower total cholesterol (184.74+/-33.23 vs 202.01+/-41.05 mg/dl); and lower LDL-C (119.63+/-31.59 vs 135.89+/-39.50 mg/dl). Hs-CRP was significantly lower (0.14+/-0.23 vs 0.23+/-0.44 mg/dl, P=0.025), whereas homocysteine was significantly higher (10.97+/-6.69 vs 8.44+/-2.50 micromol/l, P=0.001) in vegetarians than omnivores. Taiwanese vegetarians have lower total cholesterol, LDL-C and hs-CRP levels, and higher homocysteine levels than omnivores. Owing to different predictive value of each risk factor, the Taiwanese vegetarians had a better cardiovascular risk profile than omnivores. Whether the Taiwanese vegetarian diet should be supplemented with vitamin B(12) to lower serum homocysteine level remains to be addressed.

    Full Text Available Strong competition in the market has caused the development of a new management approach known as Total Quality Management (TQM. Due to importance that quality plays in achieving competitive advantage, the hotel industry started to apply TQM. During the introduction of these systems, hotel companies may use different approaches to suit their own buseiness requirements. In doing so, 'TQM standards' can be used, or various international standards and models of business excellence Malcolm Balridge National Quality Award and European Quality Award.

  7. Periprosthetic Fractures Following Total Knee Arthroplasty

    2015-01-01

    Periprosthetic fractures after total knee arthroplasty may occur in any part of the femur, tibia and patella, and the most common pattern involves the supracondylar area of the distal femur. Supracondylar periprosthetic fractures frequently occur above a well-fixed prosthesis, and risk factors include anterior femoral cortical notching and use of the rotational constrained implant. Periprosthetic tibial fractures are frequently associated with loose components and malalignment or malposition of implants. Fractures of the patella are much less common and associated with rheumatoid arthritis, use of steroid, osteonecrosis and malalignment of implants. Most patients with periprosthetic fractures around the knee are the elderly with poor bone quality. There are many difficulties and increased risk of nonunion after treatment because reduction and internal fixation is interfered with by preexisting prosthesis and bone cement. Additionally, previous soft tissue injury is another disadvantageous condition for bone healing. Many authors reported good clinical outcomes after non-operative treatment of undisplaced or minimally displaced periprosthetic fractures; however, open reduction or revision arthroplasty was required in displaced fractures or fractures with unstable prosthesis. Periprosthetic fractures around the knee should be prevented by appropriate technique during total knee arthroplasty. Nevertheless, if a periprosthetic fracture occurs, an appropriate treatment method should be selected considering the stability of the prosthesis, displacement of fracture and bone quality.

    This report outlines the technical progress achieved for project DE-FC26-03NT41785 (Total Ore Processing Integration and Management) during the period 01 October through 31 December of 2005. Graphical analysis of blast patterns according to drill monitor data is continuing. Multiple linear regression analysis of 16 mine and mill variables (powder factor, two modeled size fractions, liberation index, predicted grind, total crude Fe, Satmagan Fe, sat ratio, DSC, geologic blend, ambient temperature, cobbing hours, feeder plugs, and percent feeder run time-of-mill time) indicates that December variations in plant performance are generally predictable (Figure 1). The outlier on December 28th coincides with low cobbing availability and equipment downtime. Mill productivity appeared to be most influenced, as usual, by ore quality as indicated by the liberation index--the higher the liberation index, the lower the throughput. The upcoming quarter will be concerned with wrapping up the work in progress, such as the detailed statistical analyses, and writing a final report. Hibtac Mine engineers are evaluating neural network software to determine its utility for modeling, and eventually predicting, mill throughput.

  9. Total colonic aganglionosis in Hirschsprung disease.

    Moore, Samuel W

    2012-11-01

    Total colonic aganglionosis (TCA) is a relatively uncommon form of Hirschsprung disease (HSCR), occurring in approximately 2%-13% of cases. It can probably be classified as TCA (defined as aganglionosis extending from the anus to at least the ileocecal valve, but not >50 cm proximal to the ileocecal valve) and total colonic and small bowel aganglionosis, which may involve a very long segment of aganglionosis. It is not yet clear whether TCA merely represents a long form of HSCR or a different expression of the disease. There are many differences between TCA and other forms of HSCR, which require explanation if its ubiquitous clinical features are to be understood. Clinically, TCA appears to represent a different spectrum of disease in terms of presentation and difficulties that may be experienced in diagnosis, suggesting a different pathophysiology from the more common forms of HSCR. There is also some evidence suggesting that instead of being purely congenital, it may represent certain different pathophysiologic mechanisms. This study, in addition to reviewing current understanding and differences between TCA and the more frequently encountered rectosigmoid (or short-segment) expression, correlates them with what is currently known about the genetic and molecular biological background. Moreover, it reviews current outcomes to find consensus on management. Copyright © 2012. Published by Elsevier Inc.

    Hip dislocation is a major and common complication of total hip arthroplasty (THA), which appears with an incidence between 0.3% and 10% in primary total hip arthroplasties and up to 28% in revision THA. The hip dislocations can be classified into three groups: early, intermediate and late. Approximately two-thirds of cases can be treated successfully with a non-operative approach. The rest require further surgical intervention. The prerequisite to developing an appropriate treatment strategy is a thorough evaluation to identify the causes of the dislocation. In addition, many factors that contribute to THA dislocation are related to the surgical technique, mainly including component orientation, femoral head diameter, restoration of femoral offset and leg length, cam impingement and condition of the soft tissues. The diagnosis of a dislocated hip is relatively easy because the clinical situation is very typical. Having identified a dislocated hip, the first step is to perform a closed reduction of the implant. After reduction you must perform a computed tomography scan to evaluate the surgical options for treatment of recurrent dislocation that include: revision arthroplasty, modular components exchange, dual-mobility cups, large femoral heads, constrained cups, elimination of impingement and soft tissue procedures. The objective is to avoid further dislocation, a devastating event which is increasing the number of operations on the hip. To obtain this goal is useful to follow an algorithm of treatment, but the best treatment remains prevention.

    2014-12-01

    Full Text Available Ammonia is generated in mainstream smoke (MSS from multiple precursors in tobacco such as amino acids, proteins, nitrates and ammonium salts. Ammonia derived from both the particulate and vapor phases is measured with the particulate phase contributing greater than 80% of the total ammonia. The general approach of the analytical methods involved the collection of MSS by either electrostatic precipitation (EP or impingers with acidic solution combined with Cambridge filters (CF, 44 or 92 mm and the analysis of ammonium cations by ion chromatography (IC with a conductivity detector. The available results from both internal testing and external literature for 1R4F Kentucky reference cigarettes, smoked under Federal Trade Commission (FTC puffing conditions, showed a wide range of yields from approximately 5 to 18 µg/cig of ammonia. To investigate possible causes for this wide range and to optimize the analytical method, several parameters deemed critical to the results were studied using 1R4F. They include the type of acids (hydrochloric acid, sulfuric acid and malic acid, acid strength (0.005 M to 0.1 M, trapping efficiency and sample stability. The study showed that the type and concentration of acids was not significantly related to the total ammonia content in MSS. The study also indicated that the size and type of trapping devices, such as CF pads, acid treated CF pads and EP tube, did not significantly affect the trapping efficiency.

    Full Text Available Surgeries for total knee replacement (TKR are increasing and in this context there is a need to develop new protocols for management and use of blood transfusion therapy. Autologous blood reduces the need for allogeneic blood transfusion and the aim of the present study was to verify the safety and the clinical efficacy. An observational retrospective study has been conducted on 124 patients, undergoing cemented total knee prosthesis replacement. Observed population was stratified into two groups: the first group received reinfusion of autologous blood collected in the postoperative surgery and the second group did not receive autologous blood reinfusion. Analysis of data shows that patients undergoing autologous blood reinfusion received less homologous blood bags (10.6% versus 30%; p=0.08 and reduced days of hospitalization (7.88 ± 0.7 days versus 8.96 ± 2.47 days for the control group; p=0.03. Microbiological tests were negative in all postoperatively salvaged and reinfused units. Our results emphasize the effectiveness of this procedure and have the characteristics of simplicity, low cost (€97.53 versus €103.79; p<0.01, and easy reproducibility. Use of autologous drainage system postoperatively is a procedure that allows reducing transfusion of homologous blood bags in patients undergoing TKR.

    This report describes the efforts completed during the contract period beginning November 1, 1990 and ending April 30, 1991. Samples of product hygiene and potable water from WRT 3A were supplied by NASA/MSFC prior to contract award on July 24, 1990. Humidity condensate samples were supplied on August 3, 1990. During the course of this contract chemical analyses were performed on these samples to qualitatively determine specific components comprising, the measured organic carbon concentration. In addition, these samples and known standard solutions were used to identify and develop methodology useful to future comprehensive characterization of similar samples. Standard analyses including pH, conductivity, and total organic carbon (TOC) were conducted. Colorimetric and enzyme linked assays for total protein, bile acid, B-hydroxybutyric acid, methylene blue active substances (MBAS), urea nitrogen, ammonia, and glucose were also performed. Gas chromatographic procedures for non-volatile fatty acids and EPA priority pollutants were also performed. Liquid chromatography was used to screen for non-volatile, water soluble compounds not amenable to GC techniques. Methods development efforts were initiated to separate and quantitate certain chemical classes not classically analyzed in water and wastewater samples. These included carbohydrates, organic acids, and amino acids. Finally, efforts were initiated to identify useful concentration techniques to enhance detection limits and recovery of non-volatile, water soluble compounds.

    Hirschsprung disease (HD) is a functional obstruction of the bowel caused by the absence of intrinsic enteric ganglion cells. The diagnosis of total colonic HD (TCHD) based on contrast enemas is difficult in newborns because radiological findings vary. To evaluate the radiographic and contrast enema findings in patients with pathologically proven TCHD. From 1966 to 2007, 17 records from a total of 31 patients with TCHD were retrospectively evaluated for diameter and shape of the colon, diameter of the small bowel, bowel wall contour, ileal reflux, abdominal calcifications, pneumoperitoneum, filling defects, transitional zones and rectosigmoid index. Three colonic patterns of TCHD were found: microcolon, question-mark-shape colon and normal caliber colon. Additional findings included spasmodic colon, ileal reflux, delayed evacuation and abdominal calcifications. Colonic transitional zones were found in eight patients with TCHD. The diagnosis of TCHD is difficult to establish by contrast enema studies. The length of the aganglionic small bowel and the age of the patient can influence the radiological findings in TCHD. The transitional zone and the rectosigmoid index can be false-positive in TCHD. The colon can appear normal. Consider TCHD if the contrast enema study is normal but the patient remains symptomatic and other causes of distal bowel obstruction have been excluded. (orig.)

    Total body photography may aid in melanoma screening but is not widely applied due to time and cost. We hypothesized that a near-simultaneous automated skin photo-acquisition system would be acceptable to patients and could rapidly obtain total body images that enable visualization of pigmented skin lesions. From February to May 2009, a study of 20 volunteers was performed at the University of Virginia to test a prototype 16-camera imaging booth built by the research team and to guide development of special purpose software. For each participant, images were obtained before and after marking 10 lesions (five "easy" and five "difficult"), and images were evaluated to estimate visualization rates. Imaging logistical challenges were scored by the operator, and participant opinion was assessed by questionnaire. Average time for image capture was three minutes (range 2-5). All 55 "easy" lesions were visualized (sensitivity 100%, 90% CI 95-100%), and 54/55 "difficult" lesions were visualized (sensitivity 98%, 90% CI 92-100%). Operators and patients graded the imaging process favorably, with challenges identified regarding lighting and positioning. Rapid-acquisition automated skin photography is feasible with a low-cost system, with excellent lesion visualization and participant acceptance. These data provide a basis for employing this method in clinical melanoma screening. © 2014 The International Society of Dermatology.

    Full Text Available Deformation analysis is one of the main research fields in geodesy. Deformation analysis process comprises measurement and analysis phases. Measurements can be collected using several techniques. The output of the evaluation of the measurements is mainly point positions. In the deformation analysis phase, the coordinate changes in the point positions are investigated. Several models or approaches can be employed for the analysis. One approach is based on a Helmert or similarity coordinate transformation where the displacements and the respective covariance matrix are transformed into a unique datum. Traditionally a Least Squares (LS technique is used for the transformation procedure. Another approach that could be introduced as an alternative methodology is the Total Least Squares (TLS that is considerably a new approach in geodetic applications. In this study, in order to determine point displacements, 3-D coordinate transformations based on the Helmert transformation model were carried out individually by the Least Squares (LS and the Total Least Squares (TLS, respectively. The data used in this study was collected by GPS technique in a landslide area located nearby Istanbul. The results obtained from these two approaches have been compared.

    Full Text Available Forest ecosystems are often defeated in decisions about investment and economic development.  There is a very wide gap between policy makers and development investment on the one hand and environmentalists on the other hand, who see the forest ecosystem from the perspective of ecology and environment.  The first party considers that forest ecosystems have a low value, while the second party often shows very fantastic figures about the economic value of forests. From the second party's point of view, the first party could be ignorant or having a short-term interest; while from the first party's point of view, the second party loves to produce the figures that are too good to be true.  As a result, the total economic value of ecosystems is not only ignored as a consideration in investment decisions, but the total economic value of ecosystems has been seen as a boring scientific joke.  Why did the gap occur and how to close the gap will be discussed in this paper.  Economic valuation of ecosystem needs to be done more realistically so that the results are more plausible before policy makers. On the contrary, policy makers need to be aware that once a species vanished it never goes back.Keywords: ecosystem, goods and services, value, trade-off, double counting DOI: 10.7226/jtfm.19.3.201

    C ledgeriana is a medicinal plant that contains alkaloids, especially on the barks for commercial production of quinine as antimalarial. The main alkaloids in this plant are cinchonine, cinchonidine, quinine and quinidine. Besides for antiamalarial this plant is also commonly used to treat whooping cough, influenza and dysentery. Compare to other medicinal plants, nowadays only very few studies were conducted in Cinchona species. Our current study aims to determine the content of phytochemical, total phenol and total flavonoids from C. ledgeriana leaves 70% ethanol extract. The extraction was performed by maceration method using 70% ethanol solvent and then fractionated into hexane, ethylacetate and butanol. Phytochemical screening was performed to determine the content of alkaloids, flavonoids, terpenoids, tannins and saponins. Total phenol and flavonoid contents of the extract were determined by Folin-Ciocalteu and alumunium chloride colorimetric methods using gallic acid and quercetin as standards. The antioxidant activity was determined by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity. The results of phytochemical screening showed that the 70% ethanol extract of C. ledgeriana leaves contained alkaloids, flavonoids, terpenoids, tannins and saponins. The total phenol and total flavonoids analysis showed that ethyl acetate fraction had the highest total phenol (40.23%) and total flavonoids (65.34%).

    Highlights: • We have measured the total hemispherical emissivity for Inconel 718 from about 600–1250 K. • Oxidation in air at 1073 K resulted in an increase in emissivity. • Sandblasting of Inconel 718 was also observed to increase the emissivity. • Coating of graphite powder onto the ‘as-received’ Inconel 718 showed no increase in the emissivity. • Coating of graphite powder onto the 220 grit sandblasted Inconel 718 did show an increase in emissivity. - Abstract: Total hemispherical emissivity for Inconel 718 was measured in anticipation of its application in Very High Temperature Gas Reactors (VHTRs). A majority of current emissivity data for Inconel 718 is in the form of spectral measurements. The data presented here were obtained with an experimental apparatus based on the standard ASTM C835-06 for total hemispherical emittance. Measurements of Inconel 718 were made for four different surface types including: (i) ‘as-received’ from the manufacturer, (ii) oxidized in air and humidified helium, (iii) sandblasted with aluminum oxide powder, and (iv) with a thin coating of nuclear grade graphite powder (grade NGB-18). The emissivity for the ‘as-received’ sample ranged from 0.21 to 0.28 in the temperature interval from 760 K to 1275 K. Oxidation in air at 1073 K resulted in an increase in emissivity into the range from 0.2 at 650 K to 0.52 at 1200 K. There was no dependence on the oxidation times studied here. Oxidation with humidified helium at 1073 K produced less of an increase in emissivity than the oxidation in air but there was an increase up to the range from 0.2 at 600 K to 0.35 at 1200 K. Sandblasting of Inconel 718 was also observed to increase the emissivity up to the range from 0.43 at 780 K to 0.53 at 1270 K when 60 grit sized powder was used and up to the range from 0.45 at 683 K to 0.57 at 1267 K when 120 and 220 grit sized powders were used. Coating of graphite powder onto the ‘as-received’ Inconel 718 showed no increase

    Current cervical total disc replacement (TDR) designs incorporate a variety of different biomaterials including polyethylene, stainless steel, titanium (Ti), and cobalt-chrome (CoCr). These materials are most important in their utilization as bearing surfaces which allow for articular motion at the disc space. Long-term biological effects of implanted materials include wear debris, host inflammatory immune reactions, and osteolysis resulting in implant failure. We review here the most common materials used in cervical TDR prosthetic devices, examine their bearing surfaces, describe the construction of the seven current cervical TDR devices that are approved for use in the United States, and discuss known adverse biological effects associated with long-term implantation of these materials. It is important to appreciate and understand the variety of biomaterials available in the design and construction of these prosthetics and the considerations which guide their implementation.

    Twenty-nine patients due to have a total hip replacement had their systemic systolic and segmental blood pressures measured prior to operation and 1 and 6 weeks postoperatively. No patients had signs of ischemia. The segmental blood pressure was measured at the ankle and at the toes. A significant...... drop was found in all pressures 1 week postoperatively. The decrease followed the systemic pressure and was restored to normal after 6 weeks. In a group of six patients with preoperatively decreased ankle pressure, a significant transient further decrease in the ankle-toe gradient pressure was found...... on the operated side. None of the patients had symptoms from the lowered pressure. We conclude that in patients without signs of ischemia, the postoperative segmental pressure decrease is reversible and therefore not dangerous....

    The aim of this paper was to develop a thermoluminescent dosimetry method for the absorbed dose determination of 6 MeV high-energy electron beams by thermoluminescent dosimetry. Total body irradiation (TBI) was performed using four dual fields angled at 252° and 285° in high-dose rate (HDR) mode. TBI measurements were investigated to estimate the absorbed dose in different anatomical parts of the patient. Experimental results were obtained using thermoluminescent detectors and solid water phantoms. The TL response of the dosimeters, as a function of the high-energy electron beam (HEEB) absorbed dose, was linear, from 0.1 to 500 cGy. The entrance skin dose (ESD) and isodose distribution on the surface of the treatment were investigated graphically. Copyright © 2012 Elsevier Ltd. All rights reserved.

    In patients with advanced laryngeal or hypopharyngeal cancer, or in cases when the disease recurs after treatment with (chemo)radiation, a total laryngectomy (TLE) is performed. For them to be able to function properly, speech rehabilitation is of the utmost importancefor these patients. For voice rehabilitation, voice prostheses or an electrolarynx can be used. Esophogus-speech can also be applied. In recent decades, voice prostheses in particular have undergone significant development. They can be considered the standard technique for rehabilitation. For dentists, it is important to realise that the anatomy of these patients has changed. In addition, many have a prior history of radiotherapy and thus an increased risk of xerostomia and osteoradionecrosis. In cases where maxillofacial surgery is indicated, the chance of osteoradionecrosis is higher. If extraction is considered, consultation with a head and neck oncology centre is necessary.

    or 3D reconstruction from noisy projections. We demonstrate that for a small signal-to-noise ratio, this new approach allows us to compute better (i.e., more reliable) reconstructions than those obtained by classical methods. This is possible due to the use of the TV reconstruction model, which...... incorporates our prior information about the solution and thus compensates for the loss of accuracy in the data. A consequence is that smaller data acquisition times can be used, thus reducing a patients exposure to X-rays in medical scanning and speeding up non-destructive measurements in materials science.......Total Variation (TV) regularization is a powerful technique for image reconstruction tasks such as denoising, in-painting, and deblurring, because of its ability to produce sharp edges in the images. In this talk we discuss the use of TV regularization for tomographic imaging, where we compute a 2D...

    The Daphniphyllum alkaloids are a large class of natural products isolated from a genus of evergreen plants widely used in Chinese herbal medicine. They display a remarkable range of biological activities, including anticancer, antioxidant, and vasorelaxation properties as well as elevation of nerve growth factor. Daphenylline is a structurally unique member among the predominately aliphatic Daphniphyllum alkaloids, and contains a tetrasubstituted arene moiety mounted on a sterically compact hexacyclic scaffold. Herein, we describe the first total synthesis of daphenylline. A gold-catalysed 6-exo-dig cyclization reaction and a subsequent intramolecular Michael addition reaction, inspired by Dixon's seminal work, were exploited to construct the bridged 6,6,5-tricyclic motif of the natural product at an early stage, and the aromatic moiety was forged through a photoinduced olefin isomerization/6π-electrocyclization cascade followed by an oxidative aromatization process.

The highlights of those improvements, described in this seventh annual Accomplishments Report, demonstrate that the people who support NASA's activities are getting more involved in quality and continuous improvement efforts. Their gains solidly support NASA's and this Nation's goal to remain a leader in space exploration and in world-wide market competition, and, when communicated to others through avenues such as this report, foster improvement efforts across government and industry. The principles in practice which led to these process refinements are important cultural elements to any organization's productivity and quality efforts. The categories in this report reflect NASA principles set forth in the 1980's and are more commonly known today as Total Quality Management (TQM): top management leadership and support; strategic planning; focus on the customer; employee training and recognition; employee empowerment and teamwork; measurement and analysis; and quality assurance.

    Full Text Available The diagnostic laboratories in India are progressively promoting higher standards and are moving towards accreditation and international acceptance. Hence, the concept of "Quality" will need to be understood and implemented. Total quality management (TQM in a laboratory is an integrated program involving all laboratory staff and management. TQM is a framework to operate and it is aiming for integration, consistency, increase in efficiency and a continuous drive for improvement. A well structured clinical virology service will include serology setup, cell culture facility and capacity for molecular diagnosis. The quality of results from the laboratory is significantly influenced by many pre-analytical and post-analytical factors which needed attention. The end goal of the TQM should be to provide the best care possible for the patient.

    BACKGROUND: Total elbow arthroplasty (TEA) is an established treatment for late-stage arthritis of the elbow. Indications have expanded to osteoarthritis and nonunion in distal humeral fractures. Information on implant survival and risk factors for revision is still sparse. The aim of this study...... was to evaluate implant survival and risk factors for revision of TEAs inserted in patients in the eastern part of Denmark in the period from 1980 until 2008. MATERIAL AND METHODS: The Danish National Patient Register provided personal identification numbers for patients who underwent TEA procedures from 1980...... until 2008. On the basis of a review of medical reports and linkage to the National Patient Register, we calculated revision rates and evaluated potential risk factors for revision, including, age, sex, period, indication for TEA, and implant design. RESULTS: We evaluated 324 primary TEA procedures...

    Tehranzadeh, J.; Schneider, R.; Freiberger, R.H.

    1981-01-01

    Ninety-four cases of clinically failed, cemented, total hip prostheses requiring surgery were reviewed to determine the accuracy of preoperative plain radiography, culture of aspirated fluid, arthrography, and bone scanning. When radiopaque cement had been used to embed the prosthesis, plain radiography was highly accurate in detecting a loose femoral component, less so in detecting a loose acetabular component. Culture of aspirated fluid was accurate in diagnosing infection. A positive arthrogram identified loosening with good accuracy; however, a negative arthrogram did not reliably exclude loosening. /sup 99/mTc bone scans frequently differentiated loosening from loosening with infection. The suggested sequence of diagnostic tests is plain radiography followed by bone scanning. If the bone scan shows diffuse augmented uptake, culture of aspirated fluid followed by arthrography is indicated.

    2016-01-01

    A total artificial heart (TAH) is the sole remaining option for patients with biventricular failure who cannot be rescued by left ventricular assist devices (LVADs) alone. However, the pulsatile TAH in clinical use today has limitations: large pump size, unknown durability, required complex anticoagulation regimen, and association with significant postsurgical complications. That pump is noisy; its large pneumatic driving lines traverse the body, with bulky external components for its drivers. Continuous-flow pumps, which caused a paradigm shift in the LVAD field, have already contributed to the rapidly evolving development of TAHs. Novel continuous-flow TAHs are only in preclinical testing or developmental stages. We here review the current state of TAHs, with recommended requirements for the TAH of the future.

    Full Text Available For a finite group $G$, we study the total character $tau_G$ afforded by the direct sum of all the non-isomorphic irreducible complex representations of $G$. We resolve for several classes of groups (the Camina $p$-groups, the generalized Camina $p$-groups, the groups which admit $(G,Z(G$ as a generalized Camina pair, the problem of existence of a polynomial $f(x in mathbb{Q}[x]$ such that $f(chi = tau_G$ for some irreducible character $chi$ of $G$. As a consequence, we completely determine the $p$-groups of order at most $p^5$ (with $p$ odd which admit such a polynomial. We deduce the characterization that these are the groups $G$ for which $Z(G$ is cyclic and $(G,Z(G$ is a generalized Camina pair and, we conjecture that this holds good for $p$-groups of any order.

    Full Text Available Single-incision laparoscopic surgery is an alternative to conventional multiport laparoscopy. Single-access laparoscopy using a transumbilical port affords maximum cosmetic benefits because the surgical incision is hidden in the umbilicus. The advantages of single-access laparoscopic surgery may include less bleeding, infection, and hernia formation and better cosmetic outcome and less pain. The disadvantages and limitations include longer surgery time, difficulty in learning the technique, and the need for specialized instruments. Ongoing refinement of the surgical technique and instrumentation is likely to expand its role in gynecologic surgery in the future. We perform single-incision total laparoscopic hysterectomy using three ports in the single transumbilical incision.

    Full Text Available The approach of Total Quality Management (TQM has been even more common and most recently its use in high education has been discussed. Likewise the enterprises producing various products, universities have also inputs, processes, and outputs. Due to conditions of competition, universities have to improve the qualities of these inputs, processes, and outputs, according to satisfaction, demands, and expectations of internal and external customers. If the TQM has been implemented in the universities with a manner that aims for customer satisfaction (students, lecturers, public and private establishments, and families, supports constant development, ensures participatory approach, and encourages working in groups, it will provide universities with effectiveness, efficiency, dynamics, and economics. In this study, common problems of universities, definitions of quality and TQM in high education, customer concept at universities, and factors affecting the quality of education have been explained. Besides, in order TQM approach to be successfully implemented in the universities, various suggestions have been presented.

    Full Text Available Nowadays the industry is one of the main economic sectors, with a major contribution to achieving and maintaining a high rate of economic growth. The processing industry operation to high economic performance requires changes in structural terms, the re-engineering of processes and management. In this regard, one of the main actions taken at the level of companies in the manufacturing industry is the implementation of quality systems. Practicing quality management system not only allows businesses to react to changes taking place in business, but also to inflict them by the controlling of the future. This paper aims to analyze the principles of Total Quality Management – TQM and will highlight the advantages that organizations could obtain by applying each principle separately in the process of management.

    Full Text Available Total hip arthroplasty through minimum anterior incision is a minimally invasive technique that allows access to the joint capsule without posting the skeletal muscle surrounding areas. Anterior surgical approach is advantageous because the hip joint is located closer to the front than the rear part of the limb. The surgical approach follows a internervous plane between superior and inferior gluteal nerves (in the side and femoral nerve (medially, without involving the muscle removal. This technique provides good access, through the same incision, both to the acetabul and the femur. It also allows better control of the acetabular cup, keeping the limb length, a decrease of dislocations rate and reduced post-operative precautions.

    Articulating components should minimise the generation of wear particles in order to optimize long-term survival of the prosthesis. A good understanding of tribological properties helps the orthopaedic surgeon to choose the most suitable bearing for each individual patient. Conventional and highly cross-linked polyethylene articulating either with metal or ceramic, ceramic-on-ceramic and metal-on-metal are the most commonly used bearing combinations. All combinations of bearing surface have their advantages and disadvantages. An appraisal of the individual patient’s objectives should be part of the assessment of the best bearing surface.

    1994-01-01

    A p-MOSFET total dose dosimeter where the gate voltage is proportional to the incident radiation dose. It is configured in an n-WELL of a p-BODY substrate. It is operated in the saturation region which is ensured by connecting the gate to the drain. The n-well is connected to zero bias. Current flow from source to drain, rather than from peripheral leakage, is ensured by configuring the device as an edgeless MOSFET where the source completely surrounds the drain. The drain junction is the only junction not connected to zero bias. The MOSFET is connected as part of the feedback loop of an operational amplifier. The operational amplifier holds the drain current fixed at a level which minimizes temperature dependence and also fixes the drain voltage. The sensitivity to radiation is made maximum by operating the MOSFET in the OFF state during radiation soak.

    2017-11-26

    Total knee arthroplasty (TKA) results in a high degree of patient satisfaction, as it provides patients with considerable medium- and long-term benefits in terms of quality of life, pain relief and function. Nevertheless, the literature reports that up to 30% of patients are dissatisfied. This dissatisfaction is directly related to the patients' quality of life, which they deem insufficient. Their quality of life depends on many physical, behavioural, social and psychological factors that are not taken into account by functional outcome scores. After describing the principles of quality of life evaluation after TKA, we will assess the effects of patient-related factors, the surgical technique and postoperative program through an exhaustive review of the literature. Patient expectations after TKA will then be outlined, particularly return to work and return to sports. Copyright © 2017. Published by Elsevier Masson SAS.

    Full Text Available Background/Aim. Infected total knee arthroplasty (TKA is a topic of great importance, because its diagnosing and treatment requires a lot of resources, and often has an unsatisfactory outcome. The aim of this study was to analyze the outcome of the treatment of infection developed following TKA. Methods. This retrospective study of infected TKAs was performed in the period from 1998 to 2008 in the Orthopedics & Traumatology Clinic of the Military Medical Academy (MMA in Belgrade. A total of 654 primary and revised TKAs were performed in the said period. We registered and surgically treated 28 infected TKAs (primary TKAs: MMA - 22, other institutions - 6. The incidence of TKA infection in the MMA was 3.36%. The most common pathogens were: Staphylococcus aureus - 14 (50% cases, and Staph. epidermidis - 3 (10.7% cases. Other isolated pathogens were: Enterococcus faecalis, Klebsiella pneum., Klebsiella spp., Streptoccocus viridans, Seratia spp, Micrococcus luteus and Peptostreptococcus spp. In one case we had mixed anaerobic flora, and in 3 cases cultures were negative. We analyzed diagnostic challenges, risk factors (such as age and previous viscosupplementation and treatment outcomes in our series of infected TKAs. Results. In our series 2 infections healed after iv antibiotics and debridement, 1 patient responded to open debridement with component retention, 4 patients responded fully to one-stage reimplantation, 10 cases responded fully to two-stage reimplantation, 11 patients ended with arthrodesis and we had 1 patient with above knee amputation. Conclusion. Two-stage reimplantation remains gold standard for treatment of infected TKA, and we recommend it as treatment of choice for eradication of infection. The antibiotic loaded spacer prothesis concept in most cases allows infection eradication, good function and high patient satisfaction.

The pain scores, QuickDASH scores, ulnar flexion, and supination for the whole group were statistically significantly better at follow-up. There were no statistically significant differences between the rheumatoid and the non-rheumatoid patients except for motion, which was better in the non-rheumatoid group. The motion obtained depended on the preoperative motion. Implant survival was 0.9 at 5–9 years. Interpretation The clinical results in terms of pain, motion, strength, and function were similar to those in previous reports. The implant survival was 0.9 at 9 years, both in rheumatoid and non-rheumatoid cases, which is an important improvement compared to the earlier generations of total wrist arthroplasty. PMID:23848216

    1990-08-01

    In young patients with advanced necrosis of the femoral head, the short- and medium-term results of total prosthesis arthroplasty are the most satisfactory. However, the prospect of aseptic loosening hangs over such arthroplasties like Damocles' sword. Reports from the literature suggest that, in addition to the age of the patient, there is also an endogenous factor that can be responsible not only for the etiology and pathogenesis of the necrosis, but also for the early loosening of the prosthesis. We have followed up 54 patients (73 hip joints) who had total hip replacement as a result of necrosis of the femoral head between 1976 and 1988. Altogether, 3 acetabular and 5 femoral shafts had to be replaced (7 patients). This corresponds to a loosening rate of 10% after an average of 4.9 years. Hence, the prosthesis changing rate is lower than that reported by other authors, but is still higher than in patients with coxarthrosis. Only 2 of 52 cemented shaft prostheses had to be replaced; the average age of these patients was 61.4 years. Of the 21 cement-free shaft implantations, 3 had to be replaced, the average age of these patients being 42.9 years. The fact that the average age of the latter patients was lower may be the reason for the revision rate not being significantly higher for the non-cemented shafts. In view of the fact that necrosis of the femoral head can rapidly result in the patient becoming an invalid if it is allowed to follow its natural course, hip joint prostheses should also be offered to younger patients.

    The placenta is the major source of oxidative stress in normal human pregnancy. The placental tissue is typically functional in postterm pregnancies. We hypothesized that such pregnancies experience deteriorating oxidative balance and increasing oxidative stress. In this case-control study, our aim was to investigate the oxidative status in postterm pregnancies comparing with term by using total antioxidant status (TAS) measurement. Fifty pregnant women who were in their 41st gestational week (GW) and whose labor had not yet started were selected for the study group. Fifty subjects whose spontaneous labor onset and who delivered before their 41st GW were included for control group. Venous blood samples were obtained from each participant before the onset of labor. A premixed reagent was used to obtain serum TAS measurements from the blood samples. The Mann-Whitney test was used to compare the groups. Age, gravity, and parity of the subjects were similar between the groups (p> 0.05). Body mass index (BMI) were statistically higher in postterm group (p =0.011). The median (interquartile range) TAS level was lower in the pregnancies beyond 41 weeks than term pregnancies [1.69 (0.12) mM vs 1.75 (0.20) mM, (p< 0.05)]. A lower total antioxidant status in past days pregnancy suggests an association with decreased oxidative status compared to term. It can be speculated that pregnancies beyond 41 weeks are associated with decreased oxidative stress and this may be play a role in the etiology of the prolonged pregnancy.

    Full Text Available Between May and September 2011 a total of 361 samples from water, sediment, macrophytes and fish tissues from the shallow, slightly alkaline Lake Neusiedl were measured for their total mercury content with cold vapour atomic absorption spectroscopy (CV-AAS. Hg content of surface water was below the LOD of 0.1 μg/L and the sediments displayed contents between 0.025 and 0.113 μg/g dw, significantly correlated with the proportion of organic components (fig 1. Although these results do not point to an anthropogenic pollution of the lake, considerable amounts of mercury could be measured in fish samples and macrophytes. Both investigated submerged plant species, namely Potamogeton pectinatus and Myriophyllum spicatum show a high potential for bioaccumulation of Hg, presenting mean values of 0.245 ± 0.152 and 0.298 ± 0.115 μg/g dw respectively. Compared to freshwater fish from other unpolluted sites high amounts of Hg could be measured (fig. 2. Biomagnification and significant differences could be observed when comparing muscle samples of the planctivorous fish species rudd Scardinus erythrophthalmus (n = 10, mean = 0.084 μg/g ww with the piscivorous perch Perca fluviatilis (n = 21, mean = 0.184 μg/g ww or pike-perch Sander lucioperca (n=9, mean = 0.205 μg/g ww respectively. Significantly lower values were measured in the muscle of the piscivorous pike Esox lucius (n = 25, mean = 0.135 μg/g ww in which a strong correlation between fish age and Hg content did not occur. In addition the muscle/liver ratio of Hg in pike was significantly lower compared to the other fish species, which points to a different Hg metabolism in pike, maybe under the specific saline alkaline conditions of this lake.

    Full Text Available UNLABELLED: Restricted sleep duration among young adults and adolescents has been shown to increase the risk of morbidities such as obesity, diabetes or accidents. However there are few epidemiological studies on normal total sleep time (TST in representative groups of teen-agers which allow to get normative data. PURPOSE: To explore perceived total sleep time on schooldays (TSTS and non schooldays (TSTN and the prevalence of sleep initiating insomnia among a nationally representative sample of teenagers. METHODS: Data from 9,251 children aged 11 to 15 years-old, 50.7% of which were boys, as part of the cross-national study 2011 HBSC were analyzed. Self-completion questionnaires were administered in classrooms. An estimate of TSTS and TSTN (week-ends and vacations was calculated based on specifically designed sleep habits report. Sleep deprivation was estimated by a TSTN - TSTS difference >2 hours. Sleep initiating nsomnia was assessed according to International classification of sleep disorders (ICSD 2. Children who reported sleeping 7 hours or less per night were considered as short sleepers. RESULTS: A serious drop of TST was observed between 11 yo and 15 yo, both during the schooldays (9 hours 26 minutes vs. 7 h 55 min.; p<0.001 and at a lesser extent during week-ends (10 h 17 min. vs. 9 h 44 min.; p<0.001. Sleep deprivation concerned 16.0% of chidren aged of 11 yo vs. 40.5% of those of 15 yo (p<0.001. Too short sleep was reported by 2.6% of the 11 yo vs. 24.6% of the 15 yo (p<0.001. CONCLUSION: Despite the obvious need for sleep in adolescence, TST drastically decreases with age among children from 11 to 15 yo which creates significant sleep debt increasing with age.

  14. [Ideal total hip prosthesis in 1993].

    Science.gov (United States)

    Delagoutte, J P; Mainard, D

    Although it is a hazardous adventure to define what is an ideal in any field, it would appear that there is a certain consensus about total hip prostheses. The fundamental principle of the total hip replacement was based on the articulation of a spheric segment, a mobile head contained in a hemispheric non-retaining element. To date, the first material is a titanium in a alloy containing 6% aluminum and 4% vanadium. The second material facing the titanium is polyethylene or alumine. Thus the joint couple could be "polyethylene-metal", or "polyethylene-alumine" or even "alumine-alumine". The hemispheric element can be a massive piece of polyethylene or formed by a peripheral metal (an open hemisphere) filled with the joint surface, itself made of polyethylene. This solution offers the possibility of changing the prosthesis in case of wear without interrupting the implant-bone contact. The first type is cemented to the bone with methyl polymethacrylate. With the second, the metallic part need not to be cemented and can be fitted to the bone by simple pressing. Several points are essential in the femoral piece. It should include a removable head so the length of the neck can be adjusted. It must fill the medullary canal as closely as possible and fill the methaphyseal space. It is fixed by a self-fitting system leading to stable secondary long-term fixation-a porous covering, sometimes with hydroxy apatite can also be useful. In certain cases it must be cemented, although the cement must only play the role of adaptation.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available Polyphenols belong to the most significant compounds with antioxidant effects in potatoes. Their content depends on several factors. The most important factor is the variety of potatoes and the conditions of their growing such as temperature, rainfall, altitude, agronomic and chemical characteristics of the soil. We have compared two potato cultivars in the study which have been grown in the Slovak localities Dolné Obdokovce and Vrbová nad Váhom (cv. Agria and Nitra, Radošina and Vrbová nad Váhom (cv. Impala. In lyophilized samples of potatoes total polyphenols content in ethanolic extracts using Folin-Ciocalteu agens and in methanolic extracts total antioxidant capacity using DPPHž were spectrophotometrically determined. The average total polyphenols content in the potato variety Impala was 604.26 ±120.70 mg.kg-1 dry matter (DM and 529.37 ±59.35 mg.kg-1 DM in the variety Agria. The average value of total antioxidant capacity, expressed in % inhibition, was 8.44 ±1.68% in the potato variety Impala and 8.09 ±1.14% in Agria. The results obtained were evaluated by One-way analysis of variance ANOVA (LSD-test, using Statistical Analysis Software Statgraphics.

    Pelvic floor functioning is an important concern for women requiring a hysterectomy for endometrial cancer. The incidence of pelvic floor symptoms has not been reported in women who have undergone a hysterectomy for early-stage endometrial cancer. We sought to evaluate pelvic floor function in women who have had surgical treatment for early-stage endometrial cancer as part of the multinational Laparoscopic Approach to Cancer of the Endometrium trial and to compare patients' outcomes who had total abdominal vs total laparoscopic hysterectomy. A multinational, phase III, randomized noninferiority trial compared disease-free survival of patients who had total abdominal hysterectomy vs total laparoscopic hysterectomy. This substudy analyzes the results from a self-administered validated questionnaire on pelvic floor symptoms (Pelvic Floor Distress Inventory) administered preoperatively, and at follow-up visits 6, 18, 30, 42, and 54 months postoperatively. Overall, 381 patients with endometrial cancer were included in the analysis (total abdominal hysterectomy, n = 195; total laparoscopic hysterectomy, n = 186). At 6 months postsurgery both groups experienced an improvement in Pelvic Floor Distress Inventory scores compared to presurgical pelvic floor well-being (total abdominal hysterectomy: mean change -11.17; 95% confidence interval, -17.11 to -5.24; total laparoscopic hysterectomy: mean change -10.25; 95% confidence interval, -16.31 to -4.19). The magnitude of change from baseline in pelvic floor symptoms did not differ between both treatment groups up to 54 months postsurgery. These findings suggest that pelvic floor function in terms of urinary, bowel, and prolapse symptoms are unlikely to deteriorate following abdominal or laparoscopic hysterectomy and are reassuring for women undergoing hysterectomy for early-stage endometrial cancer.

    Utilising a high-resolution, trap-based positron beam, we have measured both elastic and inelastic scattering of positrons from water vapour. The measurements comprise differential elastic, total elastic, and total inelastic (not including positronium formation) absolute cross sections. The energy range investigated is from 1 eV to 60 eV. Comparison with theory is made with both R-Matrix and distorted wave calculations, and with our own application of the Independent Atom Model for positron interactions.

    Our composite images of the solar corona based on extensive imaging at the total solar eclipses of 2010 (Easter Island), 2012 (Australia), and 2013 (Gabon) reveal several coronal mass ejections and other changes in coronal streamers and in polar plumes. Our resultant spatial resolution is finer than that available in imaging from spacecraft, including that from SOHO/LASCO or STEREO. We trace the eruptions back to their footpoints on the sun using imaging from SDO and SWAP, and follow them upwards through the corona, measuring velocities. The high-resolution computer compositing by Miloslav Druckmüller and Hana Druckmüllerová (2010 and 2013) and Pavlos Gaintatzis (2012) allows comparison of our images with those taken at intervals of minutes or hours along the totality path.

    To evaluate the outcomes of cemented total hip arthroplasty (THA) following a fracture of the acetabulum, with evaluation of risk factors and comparison with a patient group with no history of fracture. Between 1992 and 2016, 49 patients (33 male) with mean age of 57 years (25 to 87) underwent cemented THA at a mean of 6.5 years (0.1 to 25) following acetabular fracture. A total of 38 had undergone surgical fixation and 11 had been treated non-operatively; 13 patients died at a mean of 10.2 years after THA (0.6 to 19). Patients were assessed pre-operatively, at one year and at final follow-up (mean 9.1 years, 0.5 to 23) using the Oxford Hip Score (OHS). Implant survivorship was assessed. An age and gender-matched cohort of THAs performed for non-traumatic osteoarthritis (OA) or avascular necrosis (AVN) (n = 98) were used to compare complications and patient-reported outcome measures (PROMs). The mean time from fracture to THA was significantly shorter for patients with AVN (2.2 years) or protrusio (2.2 years) than those with post-traumatic OA (9.4 years) or infection (8.0 years) (p = 0.03). Nine contained and four uncontained defects were managed with autograft (n = 11), bulk allograft (n = 1), or trabecular metal augment (n = 1). Initial fracture management (open reduction and internal fixation or non-operative), timing of THA (>// 10 mm) were significantly higher following acetabular fracture compared with atraumatic OA/AVN and OHSs were inferior: one-year OHS (35.7 v ersus 40.2, p = 0.026); and final follow-up OHS (33.6 v ersus 40.9, p = 0.008). Cemented THA is a reasonable option for the sequelae of acetabular fracture. Higher complication rates and poorer PROMs, compared with patients undergoing THA for atraumatic causes, reflects the complex nature of these cases.

    Determination of halogen-specific total organic halogen (TOX) is vital for studies of disinfection of waters containing bromide, since total organic bromine (TOBr) is likely to be more problematic than total organic chlorine. Here, we present further halogen-specific TOX method optimisation and validation, focusing on measurement of TOBr. The optimised halogen-specific TOX method was validated based on the recovery of model compounds covering different classes of disinfection by-products (haloacetic acids, haloacetonitriles, halophenols and halogenated benzenes) and the recovery of total bromine (mass balance of TOBr and bromide concentrations) during disinfection of waters containing dissolved organic matter and bromide. The validation of a halogen-specific TOX method based on the mass balance of total bromine has not previously been reported. Very good recoveries of organic halogen from all model compounds were obtained, indicating high or complete conversion of all organic halogen in the model compound solution through to halide in the absorber solution for ion chromatography analysis. The method was also successfully applied to monitor conversion of bromide to TOBr in a groundwater treatment plant. An excellent recovery (101%) of total bromine was observed from the raw water to the post-chlorination stage. Excellent recoveries of total bromine (92%-95%) were also obtained from chlorination of a synthetic water containing dissolved organic matter and bromide, demonstrating the validity of the halogen-specific TOX method for TOBr measurement. The halogen-specific TOX method is an important tool to monitor and better understand the formation of halogenated organic compounds, in particular brominated organic compounds, in drinking water systems.

We evaluated retrospectively the first 100 primary THR operated with the new concept between 2009 and 2010, regarding operation data, radiological and clinical outcome (HOOS. All surgeries were perfomed in a standardized operation technique including navigation. The average age of the patients was 68 years (37 to 92 years, with a mean BMI of 26.5 (17 to 43. The mean time of surgery was 80 min. (55 to 130 min. The blood loss showed an average of 511.5 mL (200 to 1000 mL. No intra-operative complications occurred. The postoperative complication rate was 6%. The HOOS increased from 43 points pre-operatively to 90 (max 100 points 3 months after surgery. The radiological analysis showed an average cup inclination of 43° and a leg length discrepancy in a range of +/- 5 mm in 99%. The presented technique led to excellent clinic results, showed low complication rates and allowed correct implant positions although manpower was saved.

  2. The (Almost) Unseen Total Eclipse of 1831

    2008-03-01

    The total eclipse of August 1831 began at sunrise in Australia, swept across the western South Pacific Ocean, and ended at sunset in the central South Pacific. As a result of the eclipse's path over mostly uninhabited ocean, the region's sparse European (British) population, and near-useless local predictions of the event at Hobart and Sydney in almanacs sold to the general public, almost no one witnessed its passage. In an attempt to document the eclipse, journals of naive observers - those having no access to a prediction - were examined. Thus far, the sole record is in the Pitcairn Island Register Book. Considering the Pitcairners' extreme isolation and the rather modest partial eclipse that occurred there, the entry is a surprising one; however, it can be explained in terms of events associated with their initial removal to Tahiti in March 1831 followed by their return home in June. Further, an authoritative means to identify any issues associated with eclipse predictions compiled for private-sector almanacs came in 1833 when sweeping changes in the British Nautical Almanac's section on eclipses were instituted.

  3. Total parenteral nutrition in cancer patients.

    Bozzetti, Federico

    2007-12-01

    To report on how the parenteral nutrition of patients with advanced cancer has evolved and on the current status of research and clinical practice in this field. Clinical research has shown that parenteral nutrition may play a role in incurable cancer if patients are expected to die earlier from starvation than from tumour progression. A benefit was recently observed in hypophagic patients requiring supplemental on-demand home parenteral nutrition. There is some doubt that parenteral nutrition plays a palliative role, and data on quality of life are limited. The regimen of parenteral nutrition should be tailored to the needs of the patient, and recent data indicate a reduction in total energy expenditure and water requirements. There is interest in new lipid emulsions enriched with N-3 polyunsaturated fatty acids, which are well utilized by tumour-bearing individuals and may reduce the catabolic drive of cachectic patients. Future research is addressed at identifying parameters to help in the selection of aphagic/obstructed patients who may benefit from home parenteral nutrition, the early use of supplemental parenteral nutrition in hypophagic patients and developing a better nutritional formulation of lipid emulsions more appropriate for use in advanced cancer patients.

  4. Total least squares for anomalous change detection

    A family of difference-based anomalous change detection algorithms is derived from a total least squares (TLSQ) framework. This provides an alternative to the well-known chronochrome algorithm, which is derived from ordinary least squares. In both cases, the most anomalous changes are identified with the pixels that exhibit the largest residuals with respect to the regression of the two images against each other. The family of TLSQ-based anomalous change detectors is shown to be equivalent to the subspace RX formulation for straight anomaly detection, but applied to the stacked space. However, this family is not invariant to linear coordinate transforms. On the other hand, whitened TLSQ is coordinate invariant, and furthermore it is shown to be equivalent to the optimized covariance equalization algorithm. What whitened TLSQ offers, in addition to connecting with a common language the derivations of two of the most popular anomalous change detection algorithms - chronochrome and covariance equalization - is a generalization of these algorithms with the potential for better performance.

    The SynCardia total artificial heart (TAH) currently provides the most definitive option for patients with biventricular failure who are not candidates for isolated left ventricular (LV) assist device placement. The techniques for implantation are adaptable to almost all patients with advanced heart failure, including those with severe biventricular cardiomyopathy, complex congenital heart disease, failed LV assist devices, failed transplantations, and acquired structural heart defects that have failed or are not amenable to conventional surgical treatment. Over the years, the implantation technique has evolved in order to minimize the surgical invasiveness of the procedure, in anticipation of additional future surgery. Meticulous hemostasis with double layer sutures, use of Gore-Tex sheets around the TAH and the pericardial cavity, and use of tissue expanders to avoid contraction of pericardial cavity around the device are discussed in detail in the following report. Additionally, we will provide our experience with implantation of TAH in various challenging scenarios, such as patients with a small chest cavity, congenital heart defects, and simultaneous use of extracorporeal membrane oxygenation (ECMO).

    Clinical studies using total artificial hearts (TAHs) have demonstrated that pediatric and adult patients derive quality-of-life benefits from this form of therapy. Two clinically-approved TAHs and other pumps under development, however, have design challenges and limitations, including thromboembolic events, neurologic impairment, infection risk due to large size and percutaneous drivelines, and lack of ambulation, to name a few. To address these limitations, we are developing a hybrid-design, continuous-flow, implantable or extracorporeal, magnetically-levitated TAH for pediatric and adult patients with heart failure. This TAH has only two moving parts: an axial impeller for the pulmonary circulation and a centrifugal impeller for the systemic circulation. This device will utilize the latest generation of magnetic bearing technology. Initial geometries were established using pump design equations, and computational modeling provided insight into pump performance. The designs were the basis for prototype manufacturing and hydraulic testing. The study results demonstrate that the TAH is capable of delivering target blood flow rates of 1-6.5 L/min with pressure rises of 1-92 mm Hg for the pulmonary circulation and 24-150 mm Hg for the systemic circulation at 1500-10 000 rpm. This initial design of the TAH was successful and serves as the foundation to continue its development as a novel, more compact, nonthrombogenic, and effective therapeutic alternative for infants, children, adolescents, and adults with heart failure. © 2018 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

    Full Text Available Background: Oral fluids and food are traditionally introduced slowly after total abdominal hysterectomy (TAH. This descriptive study examined the effect and tolerance of early oral intake following this surgery. Methods: A retrospective chart review was conducted on 164 patients who had been on a clinical pathway following TAH. Comparisons in initiation of fluids and foods, and gastrointestinal effects were made between the early fed group (n=82 and the traditionally fed group (n=82. Results: Both groups had the similar gastrointestinal symptoms postoperatively, but the early fed group had an earlier bowel movement. The early fed group had a statistically significant shorter length of stay. Similar usage of anti-nausea medication and pain medication usage was noted between the two groups, except for a lower usage of Tylenol #3 (acetaminophen with codeine in the early fed group. Conclusions: This study found that early feeding could be tolerated well in TAH patients, with statistically significant improvements in usage of some pain medication and length of stay were noted in the early fed group.

    Radiologic findings of Total Colonic Aganglionosis (T.C.A) were analyzed in 15 patients with the results as follows; 1. Male to female ratio was 8:7. 2. There were six cases of small calibered colon, seven cases of normal colon and two cases of megacolon. 3. Free reflux of barium into the small bowel was observed in seven cases out of eight in which retrograde filling was tried. 4. Delayed films (24 hrs or more) were available in eight cases and most of the barium remained in bowel in six cases. 5. There were abnormal colonic contractions in three cases, decreased redundancy in five and five cases or irregular, hypertrophic mucosal wall suggesting enterocolitis. 6. Part of ileum were also aganglionic in five cases. There seems to be no pathognomonic barium enema findings in T.C.A But combination of these findings may suggest the possibility of T.C.A. T.C.A should be considered in differential diagnosis of bowel obstruction in infants. Barium enema should be complete and delayed films always be obtained.

    Failure of total ankle replacement (TAR) can be characterized by early peri-implant osteolysis even in the presence of very modest numbers of wear particles. The hypothesis of the study was that this reaction is in part mediated by autoinflammatory responses mediated via damage-associated molecular patterns (DAMPs, danger signals) and pattern-recognizing danger signal receptors (PRRs). Peri-implant tissue and control samples from 10 patients with AES implants were immunostained for hypoxia inducible factor-1α (HIF-1α), activated caspase-3, high-mobility group box 1 (HMGB1), receptor for advanced glycation end product (RAGE), and toll-like receptors TLR2 and TLR4. Results were evaluated on a 0 to 4 scale (from 0% to >50% stained area). Peri-implant tissue around failed TAR implants had a relatively high mean HIF-1α score of 3 on a scale, which however was similar in control samples. HMGB1 (a DAMP) was seen to be mobilized from nuclei to cellular cytoplasm, and the active caspase-3(+) cells were increased. All PRRs were increased in revision samples. Increased expression of HMGB1 and other danger signals together with increased PRR-dependent responsiveness could contribute to autoinflammatory peri-implantitis, multilocular cyst formation, and osteolysis in failed TAR implants.

    In adult patients, removal of the entire jejunum and ileum (a near total enterectomy (NTE)) is considered a non-survivable event as patients undergoing this procedure might also suffer from an underlying illness that will lead to bowel necrosis such as septic or cardiac shock and respiratory failure. Parenteral nutrition (PN) dependency with its associated complications and quality of life issues further complicates management decisions in this group of patients. In the following report, we discuss our institutional experience with NTE and present a comprehensive review of the literature with patients undergoing NTE with the establishment of bowel continuity and successful outcomes even in cases dating as far back as the 1950s, over a decade prior to the implementation of PN. Review of the literature revealed 26 cases of NTE. Most of these patients are young (46.7 years old), and 57 % are women. These patients were reported to be alive at 21 months of follow-up. In this report, we present an individual 51 months following NTE. We also document the oldest patient receiving an NTE (76 years old). Both of these patients are alive on home PN. In cases where there is hemodynamic stability and patients request to continue with further care, the possibility of a NTE with bowel continuity and life-long PN might be entertained.

    Six patients with extreme short bowel syndrome (4.2 +/- 4.9 cm of residual small bowel) were provided home parenteral nutrition (HPN) for 14,397 days. The average age at onset of HPN was 38 years (18-64 years). Patients maintained body weight at 97% of ideal (86-112%) with mean serum albumin of 3.7 +/- 0.6 g/dL (normal 3.5-5.8 g/dL), serum transferrin of 341 +/- 104 mg/dL (normal 200-400 mg/dL), and mean serum pre-albumin of 27.5 +/- 12.6 mg/dL (normal 16.6-43 mg/dL). Hospital admission for HPN-related complications was required 10.3 times/patient for a total of 864 hospital days and was catheter related in 71% of episodes. Catheter sepsis occurred once per 436 catheter days and required catheter removal in only 33% of instances. Five patients were able to resume an oral diet, five had returned to work or school, and three were married with family. HPN allowed return to a quality productive life with acceptable morbidity following catastrophic massive bowel resection.

    Total pancreatectomy (TP) is not more beneficial than less aggressive resection techniques for the treatment of pancreatic neoplasms and is associated with high morbidity and mortality. However, with advances in surgical techniques and glycemic monitoring, and the development of synthetic insulin and pancreatic enzymes for postoperative treatment, TP has been increasingly indicated. This is a review of the recent literature reporting the clinical outcomes after TP. We reviewed the publications reporting the use of TP starting 2007. The clinicophysiological and survival data were analyzed. Few studies evaluated the differences in clinical outcomes between TP and pancreaticoduodenectomy (PD) with inconsistent results. It was reported that while the perioperative morbidity did not decrease, the mortality decreased compared to previous literature. All patients who underwent TP required insulin and high dose of pancreatic enzyme supplements. The 5-year survival rates after TP and PD for pancreatic cancer were similar. The perioperative mortality decreased in patients who underwent TP with advances in the operative procedures and perioperative care. The long-term survival rates were similar for TP and PD. Therefore, treating pancreatic neoplasms using TP is feasible. Patients undergoing TP should receive adequate treatment with synthetic insulin and pancreatic enzyme supplements. © 2016 S.

Specifically, I argue that that intentionally “broken” or otherwise incomplete...... game systems can help nurture a distinctly self-motivated and collaborative form of play. I propose two terms: “unachievements” and “self-effacing games," which help articulate the specific qualities that distinguish broken games like B.U.T.T.O.N. from more traditional digital games.

    2011-06-01

    The number of total hip replacement (THR) surgeries has increased significantly over the last few years and patients undergoing surgery are of decreasing age. In consequence the question of the influencing factors for the survival of artificial hip joints becomes more and more urgent. The expected survival time of an implant is nowadays 15-20 years and it seems that factors for a shorter lifetime are female gender, overweight, younger age and certain indications which led to surgery, such as rheumatoid arthritis or fractures. In the early phase of rehabilitation, measures against dislocation including training of the abductor muscles are most important. Starting rehabilitation programs early after surgery has positive effects on outcome, especially when strengthening programs are included. There are different opinions concerning the question how the lifetime of a THR is influenced by sports activities. However, it seems to have been demonstrated that suitable sports activities have a positive effect and do not necessarily correlate with higher loosening rates after THR. In general, high-impact sports should be avoided. Recommended activities are cycling, swimming, aquajogging, hiking, rowing and dancing.

  15. Total Variation Inpainting using Split Bregman

    Pascal Getreuer

    2012-07-01

    Full Text Available Given an image where a specified region is unknown, image inpainting or image completion is the problem of inferring the image content in this region. Traditional retouching or inpainting is the practice of restoring aged artwork, where damaged or missing portions are repainted based on the surrounding content to approximate the original appearance. In the context of digital images, inpainting is used to restore regions of an image that are corrupted by noise or where the data is missing. Inpainting is also used to solve disocclusion, to estimate the scene behind an obscuring foreground object. A popular use of digital inpainting is object removal, for example, to remove a trashcan that disrupts a scene of otherwise natural beauty. Inpainting is an interpolation problem, filling the unknown region with a condition to agree with the known image on the boundary. A classical solution for such an interpolation is to solve Laplace's equation. However, Laplace's equation is usually unsatisfactory for images since it is overly smooth. It cannot recover a step edge passing through the region. Total variation (TV regularization is an effective inpainting technique which is capable of recovering sharp edges under some conditions (these conditions will be explained. The use of TV regularization was originally developed for image denoising by Rudin, Osher, and Fatemi and then applied to inpainting by Chan and Shen. TV-regularized inpainting does not create texture, the method is limited to inpainting the geometric structure.

    Total rupture of extraocular muscles is an infrequent clinical finding. Here we conducted this retrospective study to evaluate their causes of injury, clinical features, imaging, surgical management, and final outcomes in cases of isolated extraocular muscle rupture at a tertiary center in China. Thirty-six patients were identified (24 men and 12 women). Mean age was 34 years (range 2-60). The right eye was involved in 21 patients and the left 1 in 15. A sharp object or metal hook was the cause of this lesion in 16 patients, sinus surgery in 14 patients, traffic accident in 3 patients, orbital surgery in 2 patients, and conjunctive tumor surgery in 1 patient. The most commonly involved muscles were medial (18 patients) and inferior rectus muscles (13 patients). The function of the ruptured muscles revealed a scale of -3 to -4 defect of ocular motility and the amount of deviation in primary position varied from 10 to 140 PD (prism diopter). Computerized tomography (CT) confirmed the presence of ruptured muscles. An end-to-end muscle anastomosis was performed and 3 to 5 mm of muscle was resected in 23 patients. When the posterior border of the injured muscle could not be identified (13 patients), a partial tendon transposition was performed, together with recession of the antagonist in most patients, whereas a recession of the antagonist muscle plus a resection of the involved muscle with or without nasal periosteal fixation was performed in the remaining patients. After an average of 16.42 months of follow-up an excellent result was achieved in 23 patients and results of 13 patients were considered as a failure. In most patients, the posterior border of the ruptured muscle can be identified and an early surgery can be performed to restore function. Alternatively, a partial tendon transposition should be performed. When muscular rupture is suspected, an early orbital CT is required to confirm this possibility, which can then verify the necessity for an early surgical

    One of today's most highly regarded procedures for treating inguinal hernia is the totally extraperitoneal approach (TEP), but it can on occasion lead to recurrence. This is commonly managed with an open repair, a transabdominal preperitoneal procedure (TAPP), or another TEP. We report here on our years of experience with the latter. The endeavor to a secondary TEP is much the same as to a primary one, but certain differences are encountered as the operation proceeds. For example, many anatomical landmarks found in a first TEP cannot be seen in a second. There can also be a diminished amount of working space, and this occasionally leads to an open conversion. From September 1991 to September 2005, we repaired 1,526 hernias in 1,156 male patients, using the TEP in every case. Of these, 21 were TEPs after a previous TEP. In 3 cases, the space could not be opened, and they were converted to the open Lichtenstein. One patient had peritoneal tears that led to conversion and another had conversion because of excessive bleeding. There were no complications, no bladder or bowel injuries, no transfusions, no preperitoneal hematomas, and no fatalities. All patients were discharged the same day. A secondary TEP, open repair, and TAPP are alternative solutions to the problem of recurrence after TEP. However, any TEP involves a very prolonged learning curve for general surgeons, since they must learn the anatomy as well as the procedure, both at the same time. This is doubly true for the TEP after a previous TEP.

    Although instability can occur after reverse total shoulder arthroplasty (RTSA), the risk factors, the treatment, and ultimate fate of the implant in these patients remains poorly understood. Demographics, acute treatment, and the need for revision were evaluated in all patients with RTSAs who sustained a subsequent dislocation within the first 3 months. Standardized outcome scores were collected preoperatively and at the final follow-up. Atraumatic instability occurred in 11 patients (incidence, 2.9%) treated with RTSA early (before 3 months postsurgery). The mean time to dislocation was 3.4 weeks. These patients tended to be previously operated-on (64%), male (82%), overweight (mean body mass index (BMI) of 32.2 kg/m(2), with 82% having a BMI ≥30 kg/m(2)), and without a satisfactory subscapularis repair at initial RTSA (64%). Initial treatment included closed reduction in 9 patients, open reduction in 1, and open reduction with a thicker polyethylene insert in 1. Four experienced recurrent instability requiring a thicker polyethylene insert. Two additional patients were converted to hemiarthroplasty due to persistent instability. Visual analog pain scores (P = .014) and American Shoulder and Elbow Surgeons scores (P = .018) were significantly improved. Simple Shoulder Test scores trended towards improvement (P = .073). Early dislocations of the RTSA prosthesis were uncommon. The most common associated factors were a BMI >30 kg/m(2), male gender, subscapularis deficiency, and previous surgery; in these patients, we now use an abduction orthosis. Closed reduction alone was successful in 4 of the 9 closed reductions (44%). Five of 11 RTSAs (45%) required polyethylene exchange. The RTSA was retained in 82%, 36% with the original implant.

    Although chemical immunosuppression has been shown to benefit patients with chronic progressive multiple sclerosis (MS), it appears that chemotherapy has an appreciable oncogenic potential in patients with multiple sclerosis. Accordingly, we developed a modified total lymphoid irradiation (TLI) regimen designed to reduce toxicity and applied it to a randomized double blind trial of TLI or sham irradiation in MS. Standard TLI regimens were modified to reduce dose to 1,980 rad, lowering the superior mantle margin to midway between the thyroid cartilage and angle of the mandible (to avert xerostomia) and the lower margin of the mantle field to the inferior margin of L1 (to reduce gastrointestinal toxicity by dividing abdominal radiation between mantle and inverted Y), limiting spinal cord dose to 1,000 rad by custom-made spine blocks in the mantle and upper 2 cm of inverted Y fields, and also protecting the left kidney even if part of the spleen were shielded. Clinical efficacy was documented by the less frequent functional scale deterioration of 20 TLI treated patients with chronic progressive MS compared to to 20 sham-irradiated progressive MS patients after 12 months (16% versus 55%, p less than 0.03), 18 months (28% versus 63%, p less than 0.03), and 24 months (44% versus 74%, N.S.). Therapeutic benefit during 3 years follow-up was related to the reduction in lymphocyte count 3 months post-irradiation (p less than 0.02). Toxicity was generally mild and transient, with no instance of xerostomia, pericarditis, herpes zoster, or need to terminate treatment in TLI patients. However, menopause was induced in 2 patients and staphylococcal pneumonia in one.

    This report outlines the technical progress achieved for project DE-FC26-03NT41785 (Total Ore Processing Integration and Management) during the period 01 January through 31 March of 2006. (1) Work in Progress: Minntac Mine--Graphical analysis of drill monitor data moved from two-dimensional horizontal patterns to vertical variations in measured and calculated parameters. The rock quality index and the two dimensionless ({pi}) indices developed by Kewen Yin of the University of Minnesota are used by Minntac Mine to design their blasts, but the drill monitor data from any given pattern is obviously not available for the design of that shot. Therefore, the blast results--which are difficult to quantify in a short time--must be back-analyzed for comparison with the drill monitor data to be useful for subsequent blast designs. {pi}{sub 1} indicates the performance of the drill, while {pi}{sub 2} is a measure of the rock resistance to drilling. As would be expected, since a drill tends to perform better in rock that offers little resistance, {pi}{sub 1} and {pi}{sub 2} are strongly inversely correlated; the relationship is a power function rather than simply linear. Low values of each Pi index tend to be quantized, indicating that these two parameters may be most useful above certain minimum magnitudes. (2) Work in Progress: Hibtac Mine--Statistical examination of a data set from Hibtac Mine (Table 1) shows that incorporating information on the size distribution of material feeding from the crusher to the autogenous mills improves the predictive capability of the model somewhat (43% vs. 44% correlation coefficient), but a more important component is production data from preceding days (26% vs. 44% correlation coefficient), determined using exponentially weighted moving average predictive variables. This lag effect likely reflects the long and varied residence times of the different size fragments in the grinding mills. The rock sizes are also correlated with the geologic

    Following a report of the efficacy of total lymphoid irradiation (TLI) in the treatment of chronic progressive multiple sclerosis a further randomised double-blind placebo-controlled study was undertaken with the intention of entering 56 patients. In the event it was possible to recruit only 27 patients in a 2.5 year period. Three patients received active treatment openly and 24 were randomised to either active (14) or sham (10) treatment. Treatment was 1980 cGy to the lymphoid system and spleen or sham treatment after full simulation. The primary outcome measure was a comparison of the mean rates of change between treatment groups on the expanded Kurtzke disability scale (EDSS) over the two year follow up period. Patients were also assessed on other clinical outcome measures, psychometry, and serial MRI of the brain. Active treatment resulted in a profound and prolonged fall in T lymphocytes especially those with the CD4 marker and a reversal in CD4:CD8 ratio. No significant benefit was demonstrated on the rate of clinical disease progression (EDSS). A small but significant benefit was found on a score of bladder function. No significant benefit was demonstrated on other clinical or psychometric indices or on subjective visual analogue scales. There was a small but significant difference in the rate of accumulation of lesions on brain MRI favouring the treatment group. The treated group had a higher incidence of clinically relevant side effects, notably amenorrhoea and infections: three deaths (one in the TLI group, two in the sham treated group) occurred. A post hoc calculation indicates that the study had a possible 35% risk of a false negative result using the principal outcome measure. The study fails to confirm the previously reported clinical benefit of TLI although there may be a minor benefit on disease progression as indicated by MRI lesion counts. It is concluded that TLI cannot be recommended for the routine treatment of chronic progressive multiple

    Background: An increasing number of physically active patients not only need to know if they will basically be able to engage in sports after undergoing arthroplasty. They also would like to know whether or not they will be able to resume their preoperative activity levels. This article aims to provide an overview of recent data regarding the following questions on hip, knee and shoulder arthroplasty: (1) What is the impact of physical activity on an endoprosthesis? (2) What level of sports can be achieved after an arthroplasty procedure? (3) What types of sport are recommended for patients with an endoprosthesis? Methods: PubMed-based review of the literature. Narrative review focusing on current data from the years 2010 to 2016. Results: The commonly known recommendation to exercise low-impact sports such as hiking, swimming, cycling or golf at a moderate intensity remains valid for all types of prostheses in all joints. There is broad consensus that the benefits of these sports outweigh the negative effects. Having undergone total hip or knee arthroplasty, most patients with a high preoperative activity level return to sports after 3-6 months, albeit with a clear tendency to lower intensity and a shift from high-impact to low-impact sports. Some key questions have to be answered regarding the effects of low-impact sports that are exercised with high intensity, the effects resulting from high-impact sports, effects specific to different types of sport, and possibilities provided by different prosthesis types. In this context, a lot remains to be done to investigate the limits between positive and negative effects resulting from physical activity of varying intensity. New data suggests that generally a higher physical performance level may be achieved than has been traditionally recommended. Early results of unicondylar knee prostheses are far better than those achieved with bicondylar prostheses. In contrast to expert recommendations, shoulder endoprostheses show

    Full Text Available In this paper we propose a methodology to estimate the recovery percentage for each of the products which can be obtained from the exploitation of an ornamental granite quarry: block, semiblock, masonry-transverse stone, and the smaller materials that can be used to obtain construction aggregates. This methodology ensures that quarry exploitation is exhaustive, thereby minimising the production of spoils and the consequent negative impact on the environment. The analysis is based on a detailed and exhaustive compilation of discontinuity data from the research fronts, which are then interpreted statistically and projected over the three weakness planes that are a particular feature of ornamental granite deposits. Using this information, and bearing in mind the minimum commercially viable sizes for each kind of granite, the corresponding recovery rates are calculated for each material in each plane. The results are then integrated using spatial techniques, and the result is an evaluation of quarry contents with a view to total exploitation. This methodology was applied to a quarry in the opening phase in order to carry out an a priori assessment of the economic feasibility of the quarry.

De esta manera se logra un aprovechamiento integral de la cantera, evitándose la generación de estériles y el subsiguiente impacto ambiental producido por éstos.

    The levels of sugars, ascorbic acid, total phenolic content (TPC) and total antioxidant activity (TAA) were determined in fruit juices from seven passion fruit (Passiflora spp.) cultivars: P. edulis cultivars Purple, Frederick, Yellow, Pink, P. edulis f. flavicarpa, P. maliformis and P. quadrangularis (we also tested this cultivar's mesocarp). Purple and Yellow P. edulis had significantly higher total sugar, 142.85 ± 0.17 g kg⁻¹ and 139.69 ± 0.12 g kg⁻¹, respectively, than other cultivars. Glucose and fructose content were higher in juice from vine-ripened fruits of Purple, Frederick and Yellow P. edulis, P. quadrangularis and P. maliformis. Sucrose content was significantly higher in juice of non-vine-ripened fruits of P. edulis (Pink) and P. edulis f. flavicarpa. Ascorbic acid, TPC and TAA were significantly higher in vine-ripened Purple and Yellow P. edulis; ranges were 0.22-0.33 g kg⁻¹, 342.80-382.00 mg gallic acid equivalent L⁻¹ and 409.13-586.70 µmol Trolox L⁻¹, respectively. Based on principal component analysis (PCA) and cluster analysis, the main variables - °Brix, total sugar, glucose, fructose, ascorbic acid, TPC and TAA - formed the characteristics for the group comprising Purple and Yellow P. edulis. Glucose, fructose, sucrose, ascorbic acid, TAA and TPC were quantified in passion fruit juices. Variation of the above variables in juices of Passiflora depends on the cultivar and ripeness. © 2012 Society of Chemical Industry.

    Gastrodia elata Blume ( G. elata ), a traditional Chinese medicine, is widely used for treatment of various neuro dysfunctions. However, its quality control is still limited to the determination of gastrodin. In the present study, two novel strategies based on quantitative evaluation of total gastrodin and gastrodigenin with base hydrolysis and total gastrodigenin with base-enzymatic hydrolysis followed by HPLC-FLD were put forward and successfully applied to evaluate the quality of 47 batches of G. elata from eight localities. Meanwhile, a systematic comparison of the novel strategy with the multiple markers and the Pharmacopeia method was performed. The results showed that the parishins category could be completely hydrolyzed to gastrodin by sodium hydroxide solution, and gastrodin could further utterly hydrolyze to gastrodigenin with β-d-glucosidase buffer solution. The contents of total gastrodin and gastrodigenin ranged from 1.311% to 2.034%, and total gastrodigenin from 0.748% to 1.120% at the eight localities. From the comparison, we can conclude that the two novel strategies can comprehensively reveal the characteristics of overall active ingredients in G. elata for quality control. The present study provides a feasible and credible strategy for the quality control of G. elata , suggesting a revision of the latest Chinese Pharmacopoeia or European Pharmacopoeia methods for the modernization of G. elata use.

  9. TICMR: Total Image Constrained Material Reconstruction via Nonlocal Total Variation Regularization for Spectral CT.

    This work develops a material reconstruction method for spectral CT, namely Total Image Constrained Material Reconstruction (TICMR), to maximize the utility of projection data in terms of both spectral information and high signal-to-noise ratio (SNR). This is motivated by the following fact: when viewed as a spectrally-integrated measurement, the projection data can be used to reconstruct a total image without spectral information, which however has a relatively high SNR; when viewed as a spectrally-resolved measurement, the projection data can be utilized to reconstruct the material composition, which however has a relatively low SNR. The material reconstruction synergizes material decomposition and image reconstruction, i.e., the direct reconstruction of material compositions instead of a two-step procedure that first reconstructs images and then decomposes images. For material reconstruction with high SNR, we propose TICMR with nonlocal total variation (NLTV) regularization. That is, first we reconstruct a total image using spectrally-integrated measurement without spectral binning, and build the NLTV weights from this image that characterize nonlocal image features; then the NLTV weights are incorporated into a NLTV-based iterative material reconstruction scheme using spectrally-binned projection data, so that these weights serve as a high-SNR reference to regularize material reconstruction. Note that the nonlocal property of NLTV is essential for material reconstruction, since material compositions may have significant local intensity variations although their structural information is often similar. In terms of solution algorithm, TICMR is formulated as an iterative reconstruction method with the NLTV regularization, in which the nonlocal divergence is utilized based on the adjoint relationship. The alternating direction method of multipliers is developed to solve this sparsity optimization problem. The proposed TICMR method was validated using both simulated

    Ensemble forecasting has a long history from meteorological modelling, as an indication of the uncertainty of the forecasts. However, it is necessary to calibrate and post-process the ensembles as the they often exhibit both bias and dispersion errors. Two of the most common methods for this are Bayesian Model Averaging (Raftery et al., 2005) and Ensemble Model Output Statistics (EMOS) (Gneiting et al., 2005). There are also methods for regionalizing these methods (Berrocal et al., 2007) and for incorporating the correlation between lead times (Hemri et al., 2013). Engeland and Steinsland Engeland and Steinsland (2014) developed a framework which can estimate post-processing parameters varying in space and time, while giving a spatially and temporally consistent output. However, their method is computationally complex for our larger number of stations, which makes it unsuitable for our purpose. Our post-processing method of the ensembles is developed in the framework of the European Flood Awareness System (EFAS - http://www.efas.eu), where we are making forecasts for whole Europe, and based on observations from around 700 catchments. As the target is flood forecasting, we are also more interested in improving the forecast skill for high-flows rather than in a good prediction of the entire flow regime. EFAS uses a combination of ensemble forecasts and deterministic forecasts from different meteorological forecasters to force a distributed hydrologic model and to compute runoff ensembles for each river pixel within the model domain. Instead of showing the mean and the variability of each forecast ensemble individually, we will now post-process all model outputs to estimate the total probability, the post-processed mean and uncertainty of all ensembles. The post-processing parameters are first calibrated for each calibration location, but we are adding a spatial penalty in the calibration process to force a spatial correlation of the parameters. The penalty takes

    Full Text Available During the total eclipse of August 11, 1999 frequent showers occurred due to a unstable stratification of the air mass. At different observation sites, meteorological effects from the eclipse (99.4% coverage at Hohenpeißenberg and from showers were superimposed making it partly difficult to unambiguously interpret the observations. The weather radar at Hohenpeißenberg observatory provided a general overview of the distribution of clouds and precipitation in this area (200 km diameter. From the Garching site in the zone of totality (100% temperature and wind data taken on a 50 m mast were evaluated. By selecting periods with relatively low cloud cover it was possible to approximately follow the development of the vertical temperature and wind profiles during the eclipse. The minimum temperature at Hohenpeißenberg (about 450 m above the altitude of Garching during the eclipse was comparable to that during the previous night, the corresponding value measured at Garching remained about 2 K above the minimum observed during clear sky conditions in the previous night. Showers before, during or after the eclipse may have induced vertical exchange of air parcels. Temperatures during a shower change towards the same direction at all altitudes, thus no inversion forms. Additionally, air parcels with relatively lower concentrations of trace constituents were transported down from aloft for time periods of 10–15 minutes. These mixing processes significantly determined the temporal variations of various trace substances measured during the eclipse. Total ozone measurements at Hohenpeißenberg were performed with both DOBSON and BREWER spectrophotometers and at another site within the zone of totality by using a portable Microtops II filter instrument. Different results were obtained for both sites. These differences can be to a large extend, but not exclusively, attributed to eclipse induced shifts (limb darkening and straylight effects in the atmosphere

    Background The aim of this study was to screen various solvent extracts of whole plant of Torilis leptophylla to display potent antioxidant activity in vitro and in vivo, total phenolic and flavonoid contents in order to find possible sources for future novel antioxidants in food and pharmaceutical formulations. Material and methods A detailed study was performed on the antioxidant activity of the methanol extract of whole plant of Torilis leptophylla (TLM) and its derived fractions {n-hexane (TLH), chloroform (TLC) ethyl acetate (TLE) n-butanol (TLB) and residual aqueous fraction (TLA)} by in vitro chemical analyses and carbon tetrachloride (CCl4) induced hepatic injuries (lipid peroxidation and glutathione contents) in male Sprague-Dawley rat. The total yield, total phenolic (TPC) and total flavonoid contents (TFC) of all the fractions were also determined. TLM was also subjected to preliminary phytochemical screening test for various constituents. Results The total phenolic contents (TPC) (121.9±3.1 mg GAE/g extract) of TLM while total flavonoid contents (TFC) of TLE (60.9 ±2.2 mg RTE/g extract) were found significantly higher as compared to other solvent fractions. Phytochemical screening of TLM revealed the presence of alkaloids, anthraquinones, cardiac glycosides, coumarins, flavonoids, saponins, phlobatannins, tannins and terpenoids. The EC50 values based on the DPPH (41.0±1 μg/ml), ABTS (10.0±0.9 μg/ml) and phosphomolybdate (10.7±2 μg/ml) for TLB, hydroxyl radicals (8.0±1 μg/ml) for TLC, superoxide radicals (57.0±0.3 μg/ml) for TLM and hydrogen peroxide radicals (68.0±2 μg/ml) for TLE were generally lower showing potential antioxidant properties. A significant but marginal positive correlation was found between TPC and EC50 values for DPPH, hydroxyl, phosphomolybdate and ABTS, whereas another weak and positive correlation was determined between TFC and EC50 values for superoxide anion and hydroxyl radicals.

    A second-generation total-body electrical conductivity (TOBEC) instrument for adults (HA-2) was evaluated against isotope dilution of 2H and 18O for its ability to estimate total body water (TBW) in 20 healthy adults. The highest correlation coefficient (0.997) and the lowest standard error of the estimate (0.68 kg) were obtained using the first (FC0) and third (FC2) Fourier coefficients of the transformed TOBEC signals and the variables height (m) times average lean circumference (m) and age (y) in the prediction equation of TBW as follows: TBW (H218O) in kg = 10.8 + (0.0724.FC0) - (0.221.FC2) + (0.0398.age) + (9.2.height.average lean circumference) where average lean circumference is the average of the lean chest, abdomen, and thigh circumferences. The TOBEC instrument for adults provides a suitable alternative for the estimation of TBW.

    The objective of this study was to develop evidence-based quality indicators to measure key aspects of care that can be targeted to decrease variations in complication rates between surgeons performing total joint replacement. RAND/University of California, Los Angeles (UCLA) modified-Delphi expert panel method. To accomplish this objective, a proposed set of quality of care indicators was developed through a comprehensive literature search and structured interviews with expert clinicians. An expert panel of orthopaedic surgeons was then convened to rate the validity of these quality indicators using the RAND/UCLA Appropriateness Method. Indicators were classified as valid by the panel based on the median panel rating and the amount of dispersion of panel ratings. There were 101 candidate indicators of quality identified in the six domains of preoperative processes of care, intraoperative processes, postoperative processes, implant selection and the use of new technology, privileging of hospitals and surgeons, and outcomes and comorbidity assessment. A total of 68 of the 101 indicators were rated as valid with statistical agreement. This study identifies measures of structure, process and outcome rated as valid quality indicators for hip and knee replacement. This project provides tools to measure and improve quality of care for patients undergoing total joint replacement.

    Full Text Available INTRODUÇÃO: O tratamento cirúrgico do câncer do reto passou por grande refinamento técnico após a incorporação da excisão total do mesorreto. A possibilidade de tratamento por laparoscopia ainda permanece como motivo de controvérsia. Assim, uma revisão atualizada do assunto é pertinente para ajudar a orientar a conduta aos pacientes com esse tumor. MÉTODO: Foram consultadas as bases de dados disponíveis pelo Medline/Pubmed, Scielo e Lilacs cruzando os seguintes unitermos: câncer colorretal, laparoscopia, cirurgia. CONCLUSÃO: Até a presente data, ainda permanece motivo de controvérsia se o tratamento do câncer de reto deve ser realizado de forma rotineira por laparoscopia. Não existem dados na literatura que suportem a realização minimamente invasiva da excisão total do mesorreto para o tratamento do câncer de reto fora de protocolo de pesquisa, especialmente pela ausência de índices de sobrevida e de recidiva local com pelo menos cinco anos de seguimento.INTRODUCTION: Surgical treatment of rectal cancer has undergone great technical refinement after total mesorectal excision. The possibility of laparoscopic approach still remains controversial. Thus, an updated review of the matter is relevant to help to guide physicians in surgical treatment. METHOD: It was done an extensive review of papers on databases available through Medline / Pubmed, Lilacs and Scielo crossing the following keywords: colorectal cancer, laparoscopic surgery, surgery. CONCLUSION: To date, there still remains a matter of controversy whether the treatment of rectal cancer should be routinely performed by laparoscopy. There are no published data that support the achievement of minimally invasive total mesorectal excision for rectal cancer treatment outside the research protocol, notably a lack of survival rates and local recurrence with at least five years of follow-up.

  3. Deep vein thrombosis prophylaxis: a comprehensive approach for total hip and total knee arthroplasty patient populations.

    Miric, A; Lombardi, P; Sculco, T P

    2000-04-01

    One of the most catastrophic complications after total joint arthroplasty is a fatal pulmonary embolism. Thromboembolic disease is particularly a problem in lower extremity joint arthroplasty secondary to the development of deep vein thrombosis (DVT) and proximal propagation of the thrombus. The environment created during total hip and knee arthroplasty fulfills the criteria for DVT formation: vessel wall damage, venous stasis, and a hypercoagulable state. Evidence that suggests the insult and primary event in thrombogenesis occurs during surgery. Until recently, however, the main thrust of DVT prophylaxis has concentrated on the immediate postoperative period. A more global approach to patient care during the 6-week period beginning with surgery may result in more effective DVT prophylaxis. Operative interventions that have proven to be effective include hypotensive epidural anesthesia and intravenous administration of heparin. Postoperative pharmaceutical interventions range from standard doses of aspirin or warfarin to recently studied dosing regimens of low-molecular-weight heparins, antiplatelet agents, and antithrombotic agents. Mechanical prophylaxis has also proved to be a valuable adjunct in DVT prophylaxis during these periods. It is hoped that a more comprehensive approach incorporating several of the aforementioned treatments into a strategy that encompasses the intraoperative and early and late postoperative periods will maximize the effectiveness of DVT prophylaxis.

    Full Text Available Semen Strychni have been shown to have therapeutic effect in improving blood circulation, relieving rheumatic pain, and treating cancer. However, Semen Strychni could cause severe nephrotoxicity. The present study was designed to evaluate whether treatment with total glucosides from paeony (TGP has renoprotective effect against nephrotoxicity induced by total alkaloids from Semen Strychni (TAS. The levels of blood urea nitrogen (BUN and creatinine (Cr were determined and histopathological changes were also examined to evaluate renal injury. Moreover, a HPLC-MS method was developed and validated to investigate the comparative toxicokinetics of strychnine and brucine in rats plasma after oral administration of TAS and pretreatment with TGP. Results demonstrated that the levels of BUN and Cr were significantly increased (p<0.05 in TAS group, together with tubule epithelium cloudy swelling, degeneration, and glomerular atrophy in rats’ kidneys. The TAS-induced kidney damage was alleviated after pretreatment with TGP. Besides, Tmax of strychnine and brucine were increased and T1/2 of strychnine and brucine were decreased after pretreatment with TGP. The toxicokinetics study showed that pretreatment with TGP could attenuate the absorption of strychnine and brucine, as well as accelerate their elimination. These results suggest that TGP possesses renoprotective effects.

    The spatiotemporal distribution of total nitrogen (TN) and total phosphorus (TP) in sediments of Xiangxi Bay, Three Gorges Reservoir was investigated from October 2004 to July 2006, with related affecting factors analyzed. The TN and TP concentrations in the sediments were higher in the middle stretch but lower in the two edges of the Bay. The maximum value of TN concentration (1.08 mg x g(-1)) appeared in the middle part of the Bay, and the minimum (0.89 mg x g(-1)) occurred at the adjacent areas to the river mouth; while the maximum value of TP concentration (1.07 mg x g(-1)) appeared in the middle, and the minimum (0.80 mg x g(-1)) was in the edges of the Bay. The TN concentration decreased in the sequence of autumn-winter-spring, but increased from spring to summer dramatically; while the seasonal variation of TP concentration was not very significant, with the maximum occurred in spring. Significant inter-annual variations were observed in the TN and TP concentrations. The spatial distributions of TN and TP concentrations were mainly affected by the sedimentation of suspended matter. In the regions where sedimentation rate was high, the TN and TP concentrations were also very high. The seasonal fluctuation of TN concentration was mainly affected by river discharge, while that of TP concentration was mainly affected by point source pollution.

    2009-01-01

    To compare patient characteristics, operative variables, and outcomes of 24 patients who underwent robotic-assisted total laparoscopic hysterectomy (TLH) with 44 patients who underwent conventional TLH. We retrospectively reviewed the charts of 44 patients with TLH and 24 patients with robotic TLH. Robotic TLH was associated with a shorter hospital stay (1.0 vs 1.4 days, P=0.011) and a significant decrease in narcotic use (1.2 vs 5.0 units, P=0.002). EBL and droP in hemoglobin were not significantly different. The operative time was significantly longer in patients undergoing robotic TLH (142.2 vs 122.1 minutes, P=0.027). However, only need for laparoscopic morcellation, BMI, and uterine weight, not robotic use, were independently associated with increased operative times. Robotic hysterectomy can be performed safely with comparable operative times to those of conventional laparoscopic hysterectomy. Postoperative measures were improved over measures for conventional laparoscopy.

    During the last 30 years the production capacity of a paper machine has tripled. The fastest machines of today run over about 1600 m/min, the web width being around 10 m. The desire to further increase the production capacity is leading to more expensive paper machines and to larger buildings, if current pressing and drying techniques are used. New pressing and drying techniques will decrease the need of thermal energy. Closed water cycles reduce the need of secondary heat abundantly available from the dryer section based on cylinder drying. Total Site Integration studies are required when the effect of new process concepts are to be evaluated against energy efficiency and environmental impacts. A proto type tool has been developed and the effect of new paper machine concepts on energy consumption have been analysed. The utilisation possibilities of the surplus energy will be studied later in the course of this project. (orig.)

The antioxidant activity of the extracts was assessed using the following methods: DPPH, ABTS+ both free radicals scavenging assays, and reducing assays. TP and TF were detected by spectrophotometric and HPLC methods. In former methods, the highest amount of TP content was ethy lacetate extract (EAE, expressed as gallic acid equivalents. The greatest TF content was in the n-butanol extract (BE, expressed as lutin equivalents. No significant difference was observed in the TP/TF content between these two extracts. The antioxidant activity and TP/TF content of three extracts seemed to follow the same trend. This implied that there is a good correlation between antioxidant activities and TP/TF content. But in HPLC methods, EAE contained the highest content of lutin and gallic acid, which decreased in the same order of EAE > BE > PE, the rank order of TP/TF content of EAE and BE were different according to antioxidant ability. The overall results showed that the EAE and BE were richer in phenolics and flavonoids than petroleum ether extract (PE, and may represent a good source of antioxidants.Este estudio evaluó las actividades antioxidantes de extractos de tallos de Jasminum nervosum Lour., y el efecto de diferentes disolventes de extracción en los fenoles totales (TP y flavonoides totales (TF, y su potencial antioxidante.

    Aquaculture is one of dominant food based industry in the world with 8.3% annual growth rate and its development had led to adverse effect on the environment. High nutrient production in form of nitrogenous compound and phosphorus contributed to environmental deterioration such as eutrophication and toxicity to the industry. Usage of Effective Microorganism (EM), one of the biological approaches to remove Total Nitrogen (TN) and Total Phosphorus (TP) in aquaculture pond was proposed. Samples were obtained from the Sea Bass intensive brackish aquaculture wastewater (AW) from fish farm at Juru, Penang and the parameters used to measure the removal of nitrogenous compounds include, pH, EM dosage, shaking, contact time and optimum variable conditions. From the study, for effective contact time, day 6 is the optimum contact time for both TN and TP with 99.74% and 62.78% removal respectively while in terms of optimum pH, the highest TN removal was at pH 7 with 66.89 %. The optimum dosage of EM is 1.5 ml with ratio 1:166 for 81.5 % TN removal was also found appropriate during the experiment. At varied optimum conditions of EM, the removal efficiency of TN and TP were 81.53% and 38.94% respectively while the removal mechanism of TN was highly dependent on the decomposition rate of specific bacteria such as Nitrobacter bacteria, Yeast and Bacillus Subtilis sp. The study has established the efficacy of EM's ability to treat excessive nutrient of TN and TP from AW.

    We hypothesized that investigators could assess bone mineral content (BMC), total body mineral (M), and protein (P) from body water (W) and density (DB) based on the theory of W. E. Siri (Advances in Biological and Medical Physics, 1956, p. 239-280 and Techniques for Measuring Body Composition, 1961, p. 223-224) for body composition analysis. Siri used one or more of the body components and the densities of the body, fat (F), W, M, and P to estimate one of the remaining fractional masses. We compared M, BMC, P. F, and fat-free mass (FFM) in 31 subjects (15 women and 16 men) computed from measurements of W and DB with [4-compartment (4C) model] and without [3-compartment (3C) model] BMC (from dual X-ray absorptiometry). 4C model P was calculated by difference (P = FFM - W - M). Mean difference (P > 0.05) ranged from 0.1 to 0.8%. Correlations [+/- standard error of estimate (%)] between 4C and 3C model values were significant (r = 0.907 +/- 8.8, 0.907 +/- 8.7, 0.969 +/- 6.6, 0.998 +/- 2.0, and 0.999 +/- 0.7% for M, BMC, P, F, and FFM, respectively).

    The stability of a total nutrient admixture (TNA) has been postulated to be less than 7 days in refrigerated storage. When a TNA destabilizes, lipid particles coalesce and enlarge. Liposomes larger than 6 microns can obstruct pulmonary capillaries. A TNA containing 1500 ml of 7% Vamin, 1000 ml of 50% dextrose and 500 ml of 10% Intralipid, including the usual electrolytes, minerals and vitamins, was studied. Liposome size was measured in the original Intralipid and the TNA at intervals up to 14 days at 4 degrees C followed by 2 days at 22 degrees C. There was a small increase in liposome size up to 16 days. However, the number of particles larger than 6 microns was insignificant (by light microscopy, 3.9 +/- 2.4 [+/- SD] per 20 high-power fields; by Coulter counter, 99.8% smaller than 1.9 microns, with 0% larger than 6 microns; and by electron microscopy, 100% smaller than 2.0 microns). The osmolality and pH of the TNA were 1472 +/- 31 mOsm/kg and 5.5 +/- 0.1 respectively (mean +/- SD), with no significant change during the study times. The authors concluded that this TNA remains physically stable when refrigerated for 14 days and at room temperature for a further 2 days.

    In pancreatitis, total pancreatectomy (TP) is an effective treatment for refractory pain. Islet cell auto-transplantation (IAT) may mitigate resulting endocrinopathy. Short-term morbidity data for TP + IAT and comparisons with TP are limited. This study, using 2005-2011 National Surgical Quality Improvement Program data, examined patients with pancreatitis or benign neoplasms. Morbidity after TP alone was compared with that after TP + IAT. In 126 patients (40%) undergoing TP and 191 (60%) patients undergoing TP + IAT, the most common diagnosis was chronic pancreatitis. Benign neoplasms were present in 46 (14%) patients, six of whom underwent TP + IAT. Patients in the TP + IAT group were younger and had fewer comorbidities than those in the TP group. Despite this, major morbidity was more frequent after TP + IAT than after TP [n = 79 (41%) versus n = 36 (29%); P = 0.020]. Transfusions were more common after TP + IAT [n = 39 (20%) versus n = 9 (7%); P = 0.001], as was longer hospitalization (13 days versus 9 days; P < 0.0001). There was no difference in mortality. This study is the only comparative, multicentre study of TP and TP + IAT. The TP + IAT group experienced higher rates of major morbidity and transfusion, and longer hospitalizations. Better data on the longterm benefits of TP + IAT are needed. In the interim, this study should inform physicians and patients regarding the perioperative risks of TP + IAT. © 2013 International Hepato-Pancreato-Biliary Association.

    Total body irradiation (T.B.I.) has an established role as preparative regimen for bone-marrow transplantation in the treatment of hematological malignancies. Many randomized trials demonstrated that the clinical outcomes obtained from the association of T.B.I. and cyclophosphamide are equivalent, or, sometimes, better than those based on chemotherapeutic agents. Despite the therapeutic progress of the last years, and the consequent improvement in the overall survival, this preparative regimen remains always associated with a relatively high rate of acute and late toxicity. In this article, we review the actual indications of T.B.I. in clinical practice, and analyze the technological progress in this domain. We focus on the hypothesis that a selective irradiation of the hematopoietic or lymphoid organs is actually possible with intensity-modulated radiotherapy. Technical limits and preliminary results in terms of acute and late toxicities of intensity-modulated T.B.I. are analyzed. With these new technologies, treatment-related toxicity is not anymore a major limiting factor in the preparative regimens for bone-marrow transplantation, allowing for a larger spectrum of T.B.I. indications, a possible extension to patients older than 50 years, or a dose escalation. Preliminary results warrant, however, further evaluation in clinical trials to better assess the impact of this new approach on disease control and the long-term toxicity. (authors)

  11. On the Total k-Domination in Graphs

    Full Text Available Let G = (V, E be a graph; a set S ⊆ V is a total k-dominating set if every vertex v ∈ V has at least k neighbors in S. The total k-domination number γkt(G is the minimum cardinality among all total k-dominating sets. In this paper we obtain several tight bounds for the total k-domination number of a graph. In particular, we investigate the relationship between the total k-domination number of a graph and the order, the size, the girth, the minimum and maximum degree, the diameter, and other domination parameters of the graph.

    Accurate assessment of body composition in infants and children is fundamental to understanding normal growth and development. Validation of methods applicable to pediatric populations is needed. In the absence of a gold standard, this study was conducted to compare methods using total body water, total body potassium, total body electrical conductivity, and dual-energy x-ray absorptiometry measurements for the estimation of body fat mass in infants and toddlers. Repeated body composition measurements were performed on 76 healthy term infants at 0.5, 3, 6, 9, 12, 18, and 24 months of age. Total body water was determined by deuterium dilution and converted to fat-free mass. Total body electrical conductivity was used to measure fat mass. Total body potassium was estimated by whole-body counting and converted to fat-free mass. Dual-energy x-ray absorptiometry was used to estimate fat mass at 0.5, 12, and 24 months only. Data were analyzed by repeated measures analysis of variance, followed by Bonferroni multiple comparisons at 5%. Significant differences among methods were encountered at each age (p = 0.001-0.05). The rank order of the methods and the magnitude of the method differences were a function of age, not of gender or infant feeding mode. Wide limits of agreement imply that the methods are not interchangeable for group or individual measurements. Methods using total body water, total body potassium, total body electrical conductivity, and dual-energy x-ray absorptiometry to estimate body fat mass in infants and toddlers are not interchangeable and require further development and validation.

These complications are also correlated with poor bone quality in the elderly and often result in periprosthetic fractures. This complex orthopedic problem has very diverse clinical presentation, possibly afflicting periprosthetic fracture may happen in any bone that constitutes the knee and, due to the difficulty of finding a solution, may lead to disastrous outcomes. The treatment demands broad knowledge from the orthopedic surgeon, not only regarding arthroplasty techniques, but also osteosynthesis, as well as an elaborate therapeutic including, for example, access to a bone bank.

    Total hip and knee arthroplasty (THA and TKA) are associated with significant blood loss and some patients require postoperative blood transfusion. While tranexamic acid has been studied extensively among this population, we tested the hypothesis that epsilon aminocaproic acid (EACA) can reduce blood loss and transfusion after joint arthroplasty. In April 2014, our Veterans Affairs Medical Center introduced a protocol to administer EACA during THA and TKA. No antifibrinolytics were used previously. We retrospectively compared blood loss and incidence of transfusion among patients who underwent primary arthroplasty in the year before standardized administration of EACA with patients having the same procedures the following year. Blood loss was measured as delta hemoglobin (preoperative hemoglobin - hemoglobin on postoperative day 1). All patients undergoing primary THA or TKA were included. Patients having revision surgery were excluded. We identified 185 primary arthroplasty patients from the year before and 184 from the year after introducing the EACA protocol. There were no changes in surgical technique or attending surgeons during this period. Delta hemoglobin was significantly lower in the EACA group (2.7 ± 0.8 mg/dL) compared to the control group (3.4 ± 1.1 mg/dL) (P < .0001). The incidence of blood transfusion was also significantly lower in the EACA group (2.7%) compared to the control group (25.4%) (P < .0001). There was no difference in venous thromboembolic complications between groups. We demonstrated reductions in hemoglobin loss and transfusion following introduction of the EACA protocol in patients undergoing primary arthroplasty. EACA offers a lower cost alternative to TXA for reducing blood loss and transfusion in this population. Published by Elsevier Inc.

    Despite the large increase in total hip arthroplasties and total knee arthroplasties, the incidence and prevalence of additional contralateral or ipsilateral joint arthroplasty are poorly understood. The purpose of this study was to determine the rate of additional joint arthroplasty after a primary total hip arthroplasty or total knee arthroplasty. This historical cohort study identified population-based cohorts of patients who underwent primary total hip arthroplasty (n = 1,933) or total knee arthroplasty (n = 2,139) between 1969 and 2008. Patients underwent passive follow-up through their medical records beginning with the primary total hip arthroplasty or total knee arthroplasty. We assessed the likelihood of undergoing a subsequent total joint arthroplasty, including simultaneous and staged bilateral procedures. Age, sex, and calendar year were evaluated as potential predictors of subsequent arthroplasty. During a mean follow-up of 12 years after an initial total hip arthroplasty, we observed 422 contralateral total hip arthroplasties (29% at 20 years), 76 contralateral total knee arthroplasties (6% at 10 years), and 32 ipsilateral total knee arthroplasties (2% at 20 years). Younger age was a significant predictor of contralateral total hip arthroplasty (p hip arthroplasties (3% at 20 years), and 29 ipsilateral total hip arthroplasties (2% at 20 years). Older age was a significant predictor of ipsilateral or contralateral total hip arthroplasty (p hip arthroplasty or total knee arthroplasty can be informed of a 30% to 45% chance of a surgical procedure in a contralateral cognate joint and about a 5% chance of a surgical procedure in noncognate joints within 20 years of initial arthroplasty. Increased risk of contralateral total knee arthroplasty following an initial total hip arthroplasty may be due to gait changes prior to and/or following total hip arthroplasty. The higher prevalence of bilateral total hip arthroplasty in younger patients may result from

    Short-term results have indicated that the Bryan cervical total disc replacement (TDR) favorably compares to anterior cervical decompression and fusion, while it is associated with fewer complications and higher levels of satisfaction. The aim of the present work was to assess the safety and efficacy of the device in the treatment for cervical degenerative disc disease, at 6-year follow-up. Fifty-eighty patients have performed their 6-year follow-up visit and have been analyzed clinically and radiologically. Clinical evaluation was based on neck disability index (NDI), visual analog scale (VAS), SF-36, and range of motion (ROM) at index levels. Each measurement was taken preoperatively and at 3 months, 6 months, 1 year, 3 years, and 6 years postoperatively. Complications and re-operations were also investigated. Occurrences of heterotopic ossifications (HO) and of adjacent level degeneration were detected by radiographs at 6-year follow-up. The mean NDI and VAS scores for arm and neck were significantly reduced for all postoperative periods compared with the average preoperative values. Motion was preserved at index levels (mean ROM = 8.6° ± 0.2° at 6 years), and 81.3 % of the segments were mobile at 6 years. HO was evident in 12/64 operated segments and not restricting the movement of the prosthesis in any case at 6-year follow-up. Six of sixty-four upper adjacent levels and 4/64 lower adjacent levels showed a slight degradation. There was 2 case of posterior migration of the prosthesis, which did not cause any clinical symptoms. No case showed evidence of subsidence, wear of the implant. At a 6-year follow-up, the cervical TDR using Bryan prosthesis displayed satisfactory clinical and radiographic outcomes without any significant complication. However, future efforts need to be directed toward the evaluation of a larger number of patients with longer follow-up.

    Full Text Available Carl Schmitt is usually perceived as the theorist of total state, total war and total hostility. In the article, the author however tries to show that from 1937 to 1944, Schmitt was arguing that total war and total hostility were dangerous for Germany (as well as for the rest of Europe and warned against perpetuation of all efforts to totalize enemy that started in 1914. In his theoretical endeavors in this period there was place for the total state only - and especially for the total state strong enough to resist temptation of declaring total war on total enemy. The total state he recommended Hitler and his Nazi comrades was German Reich, as a part of Europe ordered and divided in the huge spaces (Grossraumordnung. Positioned in the centre of Europe, between the rest of the powers (France, Italy, USSR as well as the Scandinavian states, Germany should be careful enough to wage war only against its Eastern enemies (Poland and maybe USSR and only in order to achieve 'just' borders. Occupying in this way its huge space Germany should devote itself to the task of exploitation of various peoples such as Poles, Chechs and Slovaks, which were perceived as incapable of having their states and doomed to serve the master race - the Germans.

    2011-02-01

    Total variation was recently introduced in many different magnetic resonance imaging applications. The assumption of total variation is that images consist of areas, which are piecewise constant. However, in many practical magnetic resonance imaging situations, this assumption is not valid due to the inhomogeneities of the exciting B1 field and the receive coils. This work introduces the new concept of total generalized variation for magnetic resonance imaging, a new mathematical framework, which is a generalization of the total variation theory and which eliminates these restrictions. Two important applications are considered in this article, image denoising and image reconstruction from undersampled radial data sets with multiple coils. Apart from simulations, experimental results from in vivo measurements are presented where total generalized variation yielded improved image quality over conventional total variation in all cases.

    To determine whether high serum bilirubin concentrations interfere with the measurement of serum total protein concentration by refractometry and to assess potential biases among refractometer measurements. Evaluation study. Sera from 2 healthy Greyhounds. Bilirubin was dissolved in 0.1M NaOH, and the resulting solution was mixed with sera from 2 dogs from which food had been withheld to achieve various bilirubin concentrations up to 40 mg/dL. Refractometric total protein concentrations were estimated with 3 clinical refractometers. A biochemical analyzer was used to measure biuret assay-based total protein and bilirubin concentrations with spectrophotometric assays. No interference with refractometric measurement of total protein concentrations was detected with bilirubin concentrations up to 41.5 mg/dL. Biases in refractometric total protein concentrations were detected and were related to the conversion of refractive index values to total protein concentrations. Hyperbilirubinemia did not interfere with the refractometric estimation of serum total protein concentration. The agreement among total protein concentrations estimated by 3 refractometers was dependent on the method of conversion of refractive index to total protein concentration and was independent of hyperbilirubinemia.

    Achieving pain relief and improving the quality of life are the main targets of treatment for patients with chronic pancreatitis. The use of total pancreatectomy to treat chronic pancreatitis is a radical and in some ways ideal strategy. However, total pancreatectomy is associated with severe diabetic control problems. Total pancreatectomy with islet autotransplantation can relieve severe pain and prevent the development of postsurgical diabetes. With islet autotransplantation, patients with chronic pancreatitis receive their own islet cells and therefore do not require immunosuppressive therapy. In the future, total pancreatectomy with islet autotransplantation may be considered a treatment option for chronic pancreatitis patients.

    2017-01-01

    Decreases in the abundance and diversity of stream fishes in the North American Great Plains have been attributed to habitat fragmentation, altered hydrological and temperature regimes, and elevated levels of total dissolved solids and total suspended solids. Pelagic-broadcast spawning cyprinids, such as the Arkansas River Shiner Notropis girardi, may be particularly vulnerable to these changing conditions because of their reproductive strategy. Our objectives were to assess the effects of temperature, total dissolved solids, and total suspended solids on the developmental and survival rates of Arkansas River Shiner larvae. Results suggest temperature had the greatest influence on the developmental rate of Arkansas River Shiner larvae. However, embryos exposed to the higher levels of total dissolved solids and total suspended solids reached developmental stages earlier than counterparts at equivalent temperatures. Although this rapid development may be beneficial in fragmented waters, our data suggest it may be associated with lower survival rates. Furthermore, those embryos incubating at high temperatures, or in high levels of total dissolved solids and total suspended solids resulted in less viable embryos and larvae than those incubating in all other temperature, total dissolved solid, and total suspended solid treatment groups. As the Great Plains ecoregion continues to change, these results may assist in understanding reasons for past extirpations and future extirpation threats as well as predict stream reaches capable of sustaining Arkansas River Shiners and other species with similar early life-history strategies.

    Full Text Available In the present study we measured serum glucose, leptin, total cholesterol and total protein concentrations in repeat breeder cows and compared them with fertile cows. For this aim, 20 repeat breeder cows and 20 fertile cows were used as material. Repeat breeder cows were found to have lower levels of leptin and glucose as compared with fertile ones. No significant differences in total cholesterol and total protein levels were observed between the two groups. No significant correlation of leptin with glucose, total cholesterol and total protein was observed in fertile and repeat breeder cows. Low concentrations of glucose and leptin can have some effects on reproductive problems as repeat breeder and help to understand potential mechanisms impairing fertility in repeat breeder cows.

For S⊆V(G, the set I[S] is the union of all sets I[u,v] for u,v∈S. A set S⊆V(G is a total restrained geodetic set of G if I[S]=V(G and the subgraphs induced by S and V(G−S have no isolated vertex. The minimum cardinality of a total restrained geodetic set of G is the total restrained geodetic number gtr(G of G and a total restrained geodetic set of G whose cardinality equals gtr(G is a minimum total restrained geodetic set of G. A subset T of a minimum total restrained geodetic set S is a forcing subset for S if S is the unique minimum total restrained geodetic set of G containing T. The forcing total restrained geodetic number ftr(S of S is the minimum cardinality of a forcing subset of S and the forcing total restrained geodetic number ftr(G of G is the minimum forcing total restrained geodetic number among all minimum total restrained geodetic sets of G. In this article we determine all pairs a,b of integers such that ftr(G=a and gtr(G=b for some nontrivial connected graph G. Moreover, we show that the decision problem regarding that the total restrained geodetic number of a graph will be less than some positive integer r is NP-complete even when restricted to chordal graph.

    Maintaining appropriate water balance is a constant challenge for terrestrial mammals, and this problem can be exacerbated in desiccating environments. It has been proposed that natural selection has provided desert-dwelling mammals physiological mechanisms to reduce rates of total evaporative water loss. In this study, we evaluated the relationship between total evaporative water loss and body mass in mammals by using a recent phylogenetic hypothesis. We compared total evaporative water loss in 80 species of arid-zone mammals to that in 56 species that inhabit mesic regions, ranging in size from 4 g to 3,500 kg, to test the hypothesis that mammals from arid environments have lower rates of total evaporative water loss than mammals from mesic environments once phylogeny is taken into account. We found that arid species had lower rates of total evaporative water loss than mesic species when using a dichotomous variable to describe habitat (arid or mesic). We also found that total evaporative water loss was negatively correlated with the average maximum and minimum environmental temperature as well as the maximum vapor pressure deficit of the environment. Annual precipitation and the variable Q (a measure of habitat aridity) were positively correlated with total evaporative water loss. These results support the hypothesis that desert-dwelling mammals have lower rates of total evaporative water loss than mesic species after controlling for body mass and evolutionary relatedness regardless of whether categorical or continuous variables are used to describe habitat.

    Full Text Available Case. A right-handed 8-year-old female patient presented with a conventional, high-grade osteosarcoma involving her right humerus; through-shoulder amputation was recommended. After consultation, total humerus resection with expandable, total humeral endoprosthesis reconstruction was performed with a sleeve to encourage soft-tissue ingrowth. At three-year follow-up she has received one lengthening procedure and her functional scores are excellent. Conclusion. Total humeral resection and replacement in the pediatric population are rare and although early reports of expandable total humeral endoprosthesis outcomes demonstrate high failure rates, this patient’s success indicates that expandable total humeral replacement is a viable option.

  19. Correlation of total, diffuse, and direct solar radiation

    Buyco, E. H.; Namkoong, D.

    1977-01-01

    Present requirements for realistic solar energy system evaluations necessitate a comprehensive body of solar-radition data. The data should include both diffuse and direct solar radiation as well as their total on an hourly (or shorter) basis. In general, however, only the total solar radiation values were recorded. This report presents a correlation that relates the diffuse component of an hourly total solar radiation value to the total radiation ratio of the maximum value attainable. The data used were taken at the Blue Hill Observatory in Milton, Massachusetts, for the period 1952. The relation - in the form of the data plots - can be used in situations in which only the hourly total radiation data are available but the diffuse component is desired.

    Wear debris from metal-on-polyethylene articulation in conventional total hip arthroplasty can limit the implant's longevity. Modern ceramic material with high wear resistance and low fracture risk has the potential to extend the lifetime of total hip arthroplasty, which makes the procedure potentially more suitable for young, active patients. Concerns with brittle ceramic material include fracture risk, the "squeak" phenomenon, and potentially a higher dislocation rate secondary to limited neck lengths and liner options. We therefore determined the early dislocation rate in modern ceramic-on-ceramic total hip arthroplasty. In 1635 total hip arthroplasties performed over the 9-year period (1996-2005), we observed three anterior and 15 posterior dislocations (1.1%). All were treated successfully, one with a revision and 17 with closed reduction under general anesthesia. Ceramic-on-ceramic total hip arthroplasty can be a good alternative bearing surface with a low dislocation rate.

The description of a transoral robotic total laryngectomy prompted us to develop similar minimally invasive open approaches for functional total laryngectomy.MethodsA retrospective study of consecutive unselected patients with a dysfunctional larynx after (chemoradiation that underwent open maximal mucosal-sparing functional total laryngectomy (MMSTL between 2014 and 2016 is presented. The surgical technique is described, and the complications and functional outcome are reviewed.ResultsThe cohorts included 10 patients who underwent open MMSTL. No pedicled flap was used. Only one postoperative fistula was noted (10%. All patients resumed oral diet and experienced a functional tracheo-esophageal voice.ConclusionMMSTL could be used to perform functional total laryngectomy without a robot and with minimal incidence of complications.

  2. Dietary and total calcium intakes are associated with lower percentage total body and truncal fat in young, healthy adults.

    Skinner, Megan L; Simpson, Janis A Randall; Buchholz, Andrea C

    2011-12-01

    To investigate the relationship between different sources of calcium intake (dairy [milk products only], dietary [all dietary sources including dairy], nondairy dietary [all dietary sources excluding dairy], and total [dietary + supplemental]) and fat mass in young adults. One hundred ninety-seven healthy Caucasian men and women aged 18 to 28 years from southwestern Ontario underwent whole-body dual-energy x-ray absorptiometry to determine total body fat mass (%FM) and truncal fat (%TF). Calcium intakes, determined using a food frequency questionnaire, were divided into quartiles for each of dairy, dietary, nondairy dietary, and total sources. Physical activity scores were collected on a subset of subjects (n = 167). Mean %FM and %TF were compared between the lowest (Q1) and highest (Q4) quartiles of calcium consumers for each calcium source. Calcium intakes between subjects with %FM ≥ 50th and regardless of calcium source (dairy, dietary, and total). When adjusted for physical activity, lower %FM and %TF persisted (P ≤ 0.05) for subjects in Q4 (1113-1595 mg/d mean dietary and total calcium intakes) vs Q1 (116-393 mg/d mean dietary and total calcium intakes). Calcium intakes from dairy, dietary, and total sources for subjects with a %FM ≥ 50th percentile were significantly lower (all P ≤ 0.05); when adjusted for physical activity, dietary (P = 0.025) and total (P = 0.060) calcium intakes remained lower. Our findings support a relationship, even after adjusting for physical activity, between higher dietary and total calcium intakes and lower total body and truncal fat in young adults. Results suggest an intake of approximately 1500 mg/d calcium could aid in the management of body and truncal fat. We recommend that young adults be encouraged to increase their total calcium intakes to at least the recommended daily allowance of 1000 mg/d for reasons extending beyond bone health.

  3. Assessment of conservation easements, total phosphorus, and total suspended solids in West Fork Beaver Creek, Minnesota, 1999-2012

    Christensen, Victoria G.; Kieta, Kristen A.

    2014-01-01

    This study examined conservation easements and their effectiveness at reducing phosphorus and solids transport to streams. The U.S. Geological Survey cooperated with the Minnesota Board of Water and Soil Resources and worked collaboratively with the Hawk Creek Watershed Project to examine the West Fork Beaver Creek Basin in Renville County, which has the largest number of Reinvest In Minnesota land retirement contracts in the State (as of 2013). Among all conservation easement programs, a total of 24,218 acres of agricultural land were retired throughout Renville County, and 2,718 acres were retired in the West Fork Beaver Creek Basin from 1987 through 2012. Total land retirement increased steadily from 1987 until 2000. In 2000, land retirement increased sharply because of the Minnesota River Conservation Reserve Enhancement Program, then leveled off when the program ended in 2002. Streamflow data were collected during 1999 through 2011, and total phosphorus and total suspended solids data were collected during 1999 through 2012. During this period, the highest peak streamflow of 1,320 cubic feet per second was in March 2010. Total phosphorus and total suspended solids are constituents that tend to increase with increases in streamflow. Annual flow-weighted mean total-phosphorus concentrations ranged from 0.140 to 0.759 milligrams per liter, and annual flow-weighted mean total suspended solids concentrations ranged from 21.3 to 217 milligrams per liter. Annual flow-weighted mean total phosphorus and total suspended solids concentrations decreased steadily during the first 4 years of water-quality sample collection. A downward trend in flow-weighted mean total-phosphorus concentrations was significant from 1999 through 2008; however, flow-weighted total-phosphorus concentrations increased substantially in 2009, and the total phosphorus trend was no longer significant. The high annual flow-weighted mean concentrations for total phosphorus and total suspended solids

    Recurrent aphthous stomatitis is an idiopathic, chronic, recurrent inflammatory disease of the oral mucosa. It is thought that oxidative stress caused by systemic inflammation plays a basic role in the etiopathogenesis of recurrent aphthous stomatitis. The aim of this study is to review oxidative status and DNA damage in recurrent aphthous stomatitis. The study included 42 patients with an active recurrent aphthous stomatitis lesion and 39 healthy volunteers with similar demographic characteristics. DNA damage was analyzed using alkaline single cell gel electrophoresis (comet assay). Plasma levels of total antioxidant status and total oxidative status were determined by using an automated measurement method. Oxidative stress index was calculated as total oxidative status/total antioxidant status and × 100. The total oxidative status and oxidative stress index values were significantly higher in the recurrent aphthous stomatitis group compared to the control group, while total antioxidant status values were significantly lower. In the recurrent aphthous stomatitis group, DNA damage was observed to be significantly higher than the control group. In correlation analysis, significant correlation was found between DNA damage and the oxidative stress index and total oxidative status values in the recurrent aphthous stomatitis group. This is the first report in the literature that demonstrates association of recurrent aphthous stomatitis with increased oxidative status. © 2015 The International Society of Dermatology.

  5. Total Quality Management as a Paradigm of Business Success

    Directory of Open Access Journals (Sweden)

    Luburić Radoica

    2014-01-01

    Full Text Available Total Quality Management denotes a path by which - both in a stable and a transitional environment, in a professional and scientific way and by applying a variety of methods and techniques, through constant improvements and involvement of all employees - one could get to a model that enables a simultaneous achievement of the top quality level on one hand, and the top management level, on the other. Total Quality Management is a paradigm of business success in the entire world because its set up, inter alia, improves internal functions of an organisation, instils confidence in customers and triggers improvement chain reactions with suppliers and stakeholders. Quality is the foundation and client orientation is the base of the entire concept of total quality management. Placing customers at the centre is the main idea behind the entire quality concept around which everything is built. Improving the capacity of an organization to understand and meet the actual customer needs, both stated and implied, is the main objective of the total quality management. Teamwork and team leadership play a specific role in the total quality management, top managers have the key responsibilities, and activities of the medium and lower level managers together with all employees are of immeasurable significance. Managing the teamwork within the total quality management is not only a requirement for its set up, development and implementation, but also for its survival. Total Quality Management is a managerial philosophy and a mode of running a business in order to achieve success.

    2008-01-01

    INTRODUCTION The aim of this study was to determine the incidence and outcome of dislocation after total hip arthroplasty at our unit. PATIENTS AND METHODS In total, 1727 primary total joint arthroplasties and 305 revision total hip arthroplasties were performed between 1993 and 1996 at our unit. We followed up 1567 (91%) of the primary hip arthroplasties and 284 (93%) of the revision hip arthroplasties at 8–11 years after surgery. Patients were traced by postal questionnaire, telephone interview or examination of case notes of the deceased. RESULTS The dislocation rates by approach were 23 out of 555 (4.1%) for the posterior approach, 0 out of 120 (0%) for the Omega approach and 30 out of 892 (3.4%) for the modified Hardinge approach. Of dislocations after primary total hip arthroplasty, 58.5% were recurrent. The mean number of dislocations per patient was 2.81. Overall, 8.1% of revision total hip arthroplasties dislocated. 70% of these became recurrent. The mean number of dislocations per patient was 2.87. The vast majority of dislocations occurred within 2 months of surgery. DISCUSSION To our knowledge, this is the largest multisurgeon audit of dislocation after total hip arthroplasty published in the UK. The follow-up of 8–11 years is longer than most comparable studies. The results of this study can be used to inform patients as to the risk and outcome of dislocation, as well as to the risk of further dislocation. PMID:18828962

    Laparoscopic total pancreatectomy is a complicated surgical procedure and rarely been reported. This study was conducted to investigate the safety and feasibility of laparoscopic total pancreatectomy. Three patients underwent laparoscopic total pancreatectomy between May 2014 and August 2015. We reviewed their general demographic data, perioperative details, and short-term outcomes. General morbidity was assessed using Clavien-Dindo classification and delayed gastric emptying (DGE) was evaluated by International Study Group of Pancreatic Surgery (ISGPS) definition. The indications for laparoscopic total pancreatectomy were intraductal papillary mucinous neoplasm (IPMN) (n = 2) and pancreatic neuroendocrine tumor (PNET) (n = 1). All patients underwent laparoscopic pylorus and spleen-preserving total pancreatectomy, the mean operative time was 490 minutes (range 450-540 minutes), the mean estimated blood loss was 266 mL (range 100-400 minutes); 2 patients suffered from postoperative complication. All the patients recovered uneventfully with conservative treatment and discharged with a mean hospital stay 18 days (range 8-24 days). The short-term (from 108 to 600 days) follow up demonstrated 3 patients had normal and consistent glycated hemoglobin (HbA1c) level with acceptable quality of life. Laparoscopic total pancreatectomy is feasible and safe in selected patients and pylorus and spleen preserving technique should be considered. Further prospective randomized studies are needed to obtain a comprehensive understanding the role of laparoscopic technique in total pancreatectomy.

    Several recent studies have reported the benefits of tubeless percutaneous nephrolithotomy (PNL). Postoperatively, tubeless PNL patients have an indwelling ureteral stent placed, which is often associated with stent-related morbidity. We have performed totally tubeless (tubeless and stentless) PNL in which no nephrostomy tube or ureteral stent is placed postoperatively. We evaluated the safety, effectiveness, and feasibility of totally tubeless PNL. From March 2008 to February 2012, 57 selected patients underwent standard or totally tubeless PNL. Neither a nephrostomy tube nor a ureteral stent was placed in the totally tubeless PNL group. We compared patient and stone characteristics, operation time, length of hospitalization, analgesia requirements, stone-free rate, blood loss, change in creatinine, and perioperative complications between the standard and totally tubeless PNL groups. There were no significant differences in preoperative patient characteristics, postoperative complications, or the stone-free rate between the two groups, but the totally tubeless PNL group showed a shorter hospitalization and a lesser analgesic requirement compared with the standard PNL group. Blood loss and change in creatinine were not significantly different between the two groups. Totally tubeless PNL appears to be a safe and effective alternative for the management of renal stone patients and is associated with a decrease in length of hospital stay.

    Primary total hip and primary total knee surgeries are commonly performed to improve patients' quality of life and functional status. This longitudinal retrospective study (N = 851) examined self-reported quality of life and functional status over the preoperative and postoperative periods: 12 months prior to surgery, one month prior to surgery and 12 months following surgery. A linear mixed effects model was used to analyze the changes in quality of life and functional status over the sampling period. Patients in the convenience sample reported improvements in quality of life and functional status utilizing the SF-12 and Oxford Hip and Oxford Knee, although differences were noted by procedure and gender. Total hip patients tended to demonstrate greater improvement than total knee patients and males reported higher levels of physical and mental quality of life as well as functional status when compared to females. Of particular note was that mental health scores were consistently lower in both total hip and total knee replacement patients across the perioperative period and up to one year postoperative. This study identifies an opportunity for health care providers to proactively address the mental health of total hip and total knee replacement patients throughout their joint replacement trajectory.

    Full Text Available Development of scientific principles of reproducing the total financial potential of the country and its effective form is an urgent problem both in theoretical and practical aspects of the study, the solution of which is intended to ensure the active mobilization and effective use of the total financial potential of Ukraine, and as a result — its expanded reproduction as well, which would contribute to realization of the internal capacities for stabilization of the national economy. The purpose of the article is disclosing the essence of the effective form of reproducing the total financial potential of the country, analyzing the results of reproducing the total financial potential of Ukraine. It has been proved that the basis for the effective form of reproducing the total financial potential of the country is the volume and flow of resources, which are associated with the «real» economy, affect the dynamics of GDP and define it, i.e. resource and process forms of reproducing the total financial potential of Ukraine (which precede the effective one. The analysis of reproducing the total financial potential of Ukraine has shown that in the analyzed period there was an increase in the financial possibilities of the country, but steady dynamics of reduction of the total financial potential was observed. If we consider the amount of resources involved in production, creating a net value added and GDP, it occurs on a restricted basis. Growth of the total financial potential of Ukraine is connected only with extensive quantitative factors rather than intensive qualitative changes.

    Seeing a total solar eclipse is often described as a once-in-a-lifetime experience. However, for many who have experienced totality, once-in-a-lifetime is simply not enough. They want more, and are willing to go to great lengths often at great expense to repeat the experience. What is it like to experience totality? What is it about the experience that motivates these eclipse chasers? Is there an eclipse chaser personality? Can eclipse chasing actually be described as an addiction? This book describes the people who dedicate their lives to chasing their dream.

  17. Ligament balancing in total knee arthroplasty—Medial stabilizing technique

    Directory of Open Access Journals (Sweden)

    Shuichi Matsuda

    2015-10-01

    Full Text Available Ligament balancing is one of the most important surgical techniques for successful total knee arthroplasty. It has traditionally been recommended that medial and lateral as well as flexion and extension gaps are equal. This article reviews the relevant literature and discusses the clinical importance of the aforementioned gaps. Current evidence indicates that achieving medial stability throughout the range of motion should be a high priority in ligament balancing in total knee arthroplasty. Finally, the medial stabilising surgical technique, which aims to achieve good medial stability in posterior cruciate-retaining total knee arthroplasty, is introduced.

  18. Calcaneal stress fracture: an adverse event following total hip and total knee arthroplasty: a report of five cases.

    Stress fractures have been reported to occur in the pubis, femoral neck, proximal part of the tibia, and fabella during the postoperative period following total knee or total hip arthroplasty. However, to our knowledge, calcaneal stress fractures after total hip or total knee arthroplasty have not been reported in the English-language literature. Most orthopaedic surgeons are not familiar with calcaneal stress fractures that may occur in elderly patients after a total knee or total hip arthroplasty. We retrospectively reviewed the clinical features, imaging findings, and bone mineral content of the proximal part of the femur and the distal end of the radius in five patients who had a calcaneal stress fracture after a total knee or total hip arthroplasty. All patients were women with a mean age of 76.8 years. All fractures occurred in the calcaneus on the same side as the arthroplasty. The fracture appeared at a mean of 10.2 weeks postoperatively. All patients reported heel pain on walking. Swelling and local heat were found in four and three patients, respectively. Pain was elicited by squeezing the calcaneus in all patients. Early radiographs had normal findings in two patients, and an irregular sclerotic line appeared later in the radiographs of all patients. All fractures were treated conservatively. Four fractures healed uneventfully, but one fracture displaced. All patients had osteoporosis. Calcaneal stress fractures during the postoperative period following total knee or total hip arthroplasty may not be as rare as previously thought. Because clinical symptoms of the fracture appear insidiously and radiographic findings are absent or subtle in the early stage, a high index of suspicion is needed for orthopaedic surgeons to make the correct diagnosis. Magnetic resonance imaging or repeated radiographs may be necessary to make the correct diagnosis when no abnormality is apparent on the initial radiograph.

    2013-01-01

    Post-patellectomy patients represent a specific subgroup of patients that may develop arthritis and persistent knee pain and potentially require treatment with total knee arthroplasty. This article reviews the treatment and functional outcomes following total knee arthroplasty in patients with prior patellectomy. A case report is presented as an example of the clinical management of a post-patellectomy patient with significant knee pain and disability treated with total knee arthroplasty. Emphasis will be placed in decision- making, specifically with the use of a posterior stabilized implant. In addition, postoperative strengthening of the quadriceps is essential to compensate for the lack of the patella and increase the success of total knee arthroplasty in this subgroup of patients.

  9. Interspecific variation in total phenolic content in temperate brown algae

    Directory of Open Access Journals (Sweden)

    Anna Maria Mannino

    2017-09-01

    Full Text Available Marine algae synthesize secondary metabolites such as polyphenols that function as defense and protection mechanisms. Among brown algae, Fucales and Dictyotales (Phaeophyceae contain the highest levels of phenolic compounds, mainly phlorotannins, that play multiple roles. Four temperate brown algae (Cystoseira amentacea, Cystoseira compressa, Dictyopteris polypodioides and Padina pavonica were studied for total phenolic contents. Total phenolic content was determined colorimetrically with the Folin-Ciocalteu reagent. Significant differences in total phenolic content were observed between leathery and sheetlike algae and also within each morphological group. Among the four species, the sheet-like alga D. polypodioides, living in the upper infralittoral zone, showed the highest concentration of phenolic compounds. These results are in agreement with the hypothesis that total phenolic content in temperate brown algae is influenced by a combination of several factors, such as growth form, depth, and exposition to solar radiation.
