    2013-01-01

    Dry eye disease or dysfunctional tear syndrome is among the most frequent diagnoses in ophthalmology. It is a multifactorial disease of the ocular surface and tear film which results in ocular discomfort, visual disturbances, and tear instability with potential damage to the cornea and conjunctiva. Risk factors for dry eye syndrome include age, sex (female gender), race, contact lens wear, environment with low humidity, systemic medications, and autoimmune disorders. The aim of this paper is to present the systematic classification, epidemiology, diagnostic procedures, and advances in the management of dry eye disease. The recent improvements in comprehending the underlying etiologic factors will inevitably improve future classifications and diagnostic abilities leading to more effective therapeutic options. Treatment of this highly prevalent condition can drastically improve the quality of life of individuals and prevent damage to the ocular surface. PMID:24024186

    The 600% increase in medical radiation exposure to the US population since 1980 has provided immense benefit, but potential future cancer risks to patients. Most of the increase is from diagnostic radiologic procedures. The objectives of this review are to summarize epidemiologic data on cancer risks associated with diagnostic procedures, describe how exposures from recent diagnostic procedures relate to radiation levels linked with cancer occurrence, and propose a framework of strategies to reduce radiation from diagnostic imaging in patients. We briefly review radiation dose definitions, mechanisms of radiation carcinogenesis, key epidemiologic studies of medical and other radiation sources and cancer risks, and dose trends from diagnostic procedures. We describe cancer risks from experimental studies, future projected risks from current imaging procedures, and the potential for higher risks in genetically susceptible populations. To reduce future projected cancers from diagnostic procedures, we advocate widespread use of evidence-based appropriateness criteria for decisions about imaging procedures, oversight of equipment to deliver reliably the minimum radiation required to attain clinical objectives, development of electronic lifetime records of imaging procedures for patients and their physicians, and commitment by medical training programs, professional societies, and radiation protection organizations to educate all stakeholders in reducing radiation from diagnostic procedures.

    To explain observations from nonmonotonic background theories, one often needs removal of some hypotheses as well as addition of other hypotheses. Moreover, some observations should not be explained, while some are to be explained. In order to formalize these situations, extended abduction was introduced by Inoue and Sakama (1995) to generalize traditional abduction in the sense that it can compute

    2011-02-01

    Retinal vein occlusions are a common vascular disease of the eye. Ophthalmological diagnostic procedures and imaging are important for the prognosis of the disease, as are the systemic work-up and therapy. Besides routine ophthalmic tests (visual acuity, slit lamp examination, funduscopy) a work-up for glaucoma such as intraocular pressure, visual field or 24 h IOP profile is useful as a diagnostic procedure. Furthermore, new diagnostic and imaging tests such as central corneal thickness and optic nerve head imaging by Heidelberg retina tomography or optical coherence tomography (OCT) should be considered for glaucoma evaluation. Optical coherence tomography also plays a major role in treatment monitoring of macular edema secondary to retinal vein occlusions. Fluorescein angiography is well established and can provide information with regard to size and extent of the occlusion, degree of ischemia, areas of non-perfusion and neovascularization, as well as macular edema.

    Cholestatic jaundice in early infancy is a complex diagnostic problem. Misdiagnosis of cholestasis as physiologic jaundice delays the identification of severe liver diseases. In the majority of infants, prolonged physiologic jaundice represent benign cases of breast milk jaundice, but few among them are masked and caused by neonatal cholestasis (NC) that requires a prompt diagnosis and treatment. Therefore, a prolonged neonatal jaundice, longer than 2?weeks after birth, must always be investigated because an early diagnosis is essential for appropriate management. To rapidly identify the cases with cholestatic jaundice, the conjugated bilirubin needs to be determined in any infant presenting with prolonged jaundice at 14?days of age with or without depigmented stool. Once NC is confirmed, a systematic approach is the key to reliably achieve the diagnosis in order to promptly initiate the specific, and in many cases, life-saving therapy. This strategy is most important to promptly identify and treat infants with biliary atresia, the most common cause of NC, as this requires a hepatoportoenterostomy as soon as possible. Here, we provide a detailed work-up approach including initial treatment recommendations and a clinically oriented overview of possible differential diagnoses in order to facilitate the early recognition and a timely diagnosis of cholestasis. This approach warrants a broad spectrum of diagnostic procedures and investigations including new methods that are described in this review. PMID:26137452

    Although diagnostic and interventional fluoroscopic procedures are amongst the highest dose examinations performed in radiology, these procedures currently lack established national diagnostic reference levels (DRLs) in Australia. In this absence, local diagnostic reference levels (LDRLs) are proposed for a wide range of diagnostic and interventional angiographic and fluoroscopic procedures based upon data collected from 11,000 examinations, performed over a 2.5 year period at a major Australian public, teaching hospital. Each procedure type assessed included a minimum of 50 cases. LDRLs were defined for each procedure in terms of the 75th percentile of the dose area product and median fluoroscopic times have also been provided. The detailed categories of procedures used in this study may inform the Australian Radiation Protection and Nuclear Safety Agency when establishing national DRLs for angiographic and fluoroscopic procedures. Until national DRLs for these complex procedures are available, these LDRLs may provide guidance to other institutions on achievable dose levels. PMID:24430258

    2004-01-01

    The purpose of this study was to review economic considerations related to establishing a diagnosis of Crohn's disease, and to compare the costs of a diagnostic algorithm incorporating wireless capsule endoscopy (WCE) with the current algorithm for diagnosing Crohn's disease suspected in the small bowel. Published literature, clinical trial data on WCE in comparison to other diagnostic tools, and input from clinical experts were used as data sources for (1) identifying contributors to the costs of diagnosing Crohn's disease; (2) exploring where WCE should be placed within the diagnostic algorithm for Crohn's; and (3) constructing decision tree models with sensitivity analyses to explore costs (from a payor perspective) of diagnosing Crohn's disease using WCE compared to other diagnostic methods. Literature review confirms that Crohn's disease is a significant and growing public health concern from clinical, humanistic and economic perspectives, and results in a long-term burden for patients, their families, providers, insurers, and employers. Common diagnostic procedures include radiologic studies such as small bowel follow through (SBFT), enteroclysis, CT scans, ultrasounds, and MRIs, as well as serologic testing, and various forms of endoscopy. Diagnostic costs for Crohn's disease can be considerable, especially given the cycle of repeat testing due to the low diagnostic yield of certain procedures and the inability of current diagnostic procedures to image the entire small bowel. WCE has a higher average diagnostic yield than comparative procedures due to imaging clarity and the ability to visualize the entire small bowel. Literature review found the average diagnostic yield of SBFT and colonoscopy for work-up of Crohn's disease to be 53.87%, whereas WCE had a diagnostic yield of 69.59%. A simple decision tree model comparing two arms--colonoscopy and SBFT, or WCE--estimates that WCE produces a cost savings of 291dollars for each case presenting for diagnostic work-up for Crohn's. Sensitivity analysis varying diagnostic yields of colonoscopy and SBFT vs. WCE demonstrates that WCE is still less costly than SBFT and colonoscopy even at their highest reported yields, as long as the diagnostic yield of WCE is 64.10% or better. Employing WCE as a first-line diagnostic procedure appears to be less costly, from a payor perspective, than current common procedures for diagnosing suspected Crohn's disease in the small bowel. Although not addressed in this model, earlier diagnosis with WCE (due to higher diagnostic yield) also could lead to earlier management, improved quality of life and workplace productivity for people with Crohn's disease.

  16. Implication of Abduction: Complexity without Organized Interaction

    Abduction, which is articulated by C.S. Peirce, is one of the forms of inference. Abduction has been researched not only in philosophy but also in artificial intelligence and information science. Finlay and Dix's representation of abduction (1996) has almost the same meaning which is given by Peirce. On the other hand, Sawa and Gunji (2010) express three types of inference as operations of arrows on a simple triangular diagram. In the present paper, we show that Sawa-Gunji's representation of abduction is consistent with Finlay-Dix's one, and synthesize the two representations. Both parameter estimation and abduction occupy a similar position on the synthesized representation, but they are not completely corresponding. We present "incomplete" parameter estimation as a sort of "simulated abduction", since abduction has an intrinsic incompleteness, which means that abduction is formally equivalent to "the logical fallacy affirming the consequent". In other words, a numerical aspect of abduction (i.e. the simulated abduction) is formalized as incomplete parameter estimation. The concept of simulated abduction is applied to parameter estimation of auto-regressive models, and the effects of it is investigated. As a result of the numerical analyses, the distribution of the incompletely estimated parameter shows a power law of the slop -2 in the tail, although conventionally estimated parameter is normally distributed. The power law of the incompletely estimated parameter is based on the structure of ratio distribution. In other words, this result shows that the power law can arise when system observers premise a linearity of input and output data which are too small to estimate the system structure. We call the premise of the system observers "linearity bias". As an example of the cause of power law distributions, self-organized criticality (SOC) has been known. These distributions are based on the mechanisms of the systems themselves, which have some organized interaction between their elements. On the other hand, power law distribution which is derived from the incomplete parameter estimation and the linearity bias is not based on a mechanism of system itself but on relationship between data on the system and observer of the data. Consequently, our research suggests that complexity expressed by a power law distribution can be derived from the incomplete parameter estimation which is a numerical aspect of abduction and is different from SOC mechanisms.

    In logic-based diagnosis, the consistency-based method is used to determine the possible sets of faulty devices. If the fault models of the devices are incomplete or nondeterministic, then this method does not necessarily yield abductive explanations of system behavior. Such explanations give additional information about faulty behavior and can be used for prediction. Unfortunately, system descriptions for the consistency-based method are often not suitable for abductive diagnosis. Methods for completing the fault models for abductive diagnosis have been suggested informally by Poole and by Cox et al. Here we formalize these methods by introducing a standard form for system descriptions. The properties of these methods are determined in relation to consistency-based diagnosis and compared to other ideas for integrating consistency-based and abductive diagnosis.

    We present a theory, and its computer implementation, of how mental simulations underlie the abductions of informal algorithms and deductions from these algorithms. Three experiments tested the theory’s predictions, using an environment of a single railway track and a siding. This environment is akin to a universal Turing machine, but it is simple enough for nonprogrammers to use. Participants solved problems that required use of the siding to rearrange the order of cars in a train (experiment 1). Participants abduced and described in their own words algorithms that solved such problems for trains of any length, and, as the use of simulation predicts, they favored “while-loops” over “for-loops” in their descriptions (experiment 2). Given descriptions of loops of procedures, participants deduced the consequences for given trains of six cars, doing so without access to the railway environment (experiment 3). As the theory predicts, difficulty in rearranging trains depends on the numbers of moves and cars to be moved, whereas in formulating an algorithm and deducing its consequences, it depends on the Kolmogorov complexity of the algorithm. Overall, the results corroborated the use of a kinematic mental model in creating and testing informal algorithms and showed that individuals differ reliably in the ability to carry out these tasks.

    Objective To assess patient radiation doses during cerebral angiography and embolization of intracranial aneurysms in a large sample size from a single center. Materials and Methods We studied a sample of 439 diagnostic and 149 therapeutic procedures for intracranial aneurysms in 480 patients (331 females, 149 males; median age, 57 years; range, 21-88 years), which were performed in 2012 with a biplane unit. Parameters including fluoroscopic time, dose-area product (DAP), and total angiographic image frames were obtained and analyzed. Results Mean fluoroscopic time, total mean DAP, and total image frames were 12.6 minutes, 136.6 ± 44.8 Gy-cm2, and 251 ± 49 frames for diagnostic procedures, 52.9 minutes, 226.0 ± 129.2 Gy-cm2, and 241 frames for therapeutic procedures, and 52.2 minutes, 334.5 ± 184.6 Gy-cm2, and 408 frames for when both procedures were performed during the same session. The third quartiles for diagnostic reference levels (DRLs) were 14.0, 61.1, and 66.1 minutes for fluoroscopy time, 154.2, 272.8, and 393.8 Gy-cm2 for DAP, and 272, 276, and 535 for numbers of image frames in diagnostic, therapeutic, and both procedures in the same session, respectively. The proportions of fluoroscopy in DAP for the procedures were 11.4%, 50.5%, and 36.1%, respectively, for the three groups. The mean DAP for each 3-dimensional rotational angiographic acquisition was 19.2 ± 3.2 Gy-cm2. On average, rotational angiography was used 1.4 ± 0.6 times/session (range, 1-4; n = 580). Conclusion Radiation dose in our study as measured by DAP, fluoroscopy time and image frames did not differ significantly from other reported DRL studies for cerebral angiography, and DAP was lower with fewer angiographic image frames for embolization. A national registry of radiation-dose data is a necessary next step to refine the dose reference level. PMID:25469098

    Auxiliary diagnostic specialists such as clinical pathologists or radiodiagnosticians may be held liable by injured patients for erroneous diagnoses. Nearly always there will be a reconstruction of the situation in which the alleged misstake was made, and relevant facts will be tested against both professional and legal rules. The Court or one of the parties involved frequently ask an expert for re-evaluation of microscopic preparations, X-rays, etc. This objectivating evaluation requires a procedure that does justice to the original diagnostic situation and therefore should not be made by one single expert familiar with the chain of events. The results of the re-evaluation should be interpreted meticulously and their relative importance established by the Court. PMID:10746050

    The use of digital technology in the cardiac catheterization laboratory is expanding at a rapid pace. The cost-effectiveness of this new technology is yet to be proven. The aims of this study were to determine the direct cost differences of digital versus analog media (CDs) for the storage of diagnostic cardiac catheterizations and to explore the factors influencing these differences. Procedural costs of all diagnostic angiograms (n = 109), from three physicians, performed in an analog catheterization laboratory (room A) and a digital catheterization laboratory (room C) were compared during a 9-month period. The mean procedural cost was higher in room A than in room C ($1,102 vs. $1,087, P < 0.001). This cost difference was eliminated when recording media costs were excluded from analysis ($1,079 vs. $1,080, P = 0.931). Therefore, we conclude there is a procedural cost savings in a cardiac catheterization room that uses digital CDs versus cineangiogram film as the archival media. Cathet. Cardiovasc.

    Context: Escalating health care expenses pose a new challenge to the health care environment of becoming more cost-effective. There is an urgent need for more accurate data on the costs of health care procedures. Demographic changes, changing morbidity profile, and the rising impact of noncommunicable diseases are emphasizing the role of nuclear medicine (NM) in the future health care environment. However, the impact of emerging disease load and stagnant resource availability needs to be balanced by a strategic drive towards optimal utilization of available healthcare resources. Aim: The aim was to ascertain the cost of diagnostic procedures conducted at the NM Department of a tertiary health care facility by employing activity based costing (ABC) method. Materials and Methods: A descriptive cross-sectional study was carried out over a period of 1 year. ABC methodology was utilized for ascertaining unit cost of different diagnostic procedures and such costs were compared with prevalent market rates for estimating cost effectiveness of the department being studied. Results: The cost per unit procedure for various procedures varied from Rs. 869 (USD 14.48) for a thyroid scan to Rs. 11230 (USD 187.16) for a meta-iodo-benzyl-guanidine (MIBG) scan, the most cost-effective investigations being the stress thallium, technetium-99 m myocardial perfusion imaging (MPI) and MIBG scan. The costs obtained from this study were observed to be competitive when compared to prevalent market rates. Conclusion: ABC methodology provides precise costing inputs and should be used for all future costing studies in NM Departments. PMID:25400363

    Quality control of brake pads is an important issue, since the pad is a key component of the braking system. Typical damage of a brake pad assembly is the pad-backing plate detachment that affects and modifies the mechanical properties of the whole system. The most sensitive parameter to the damage is the effective Young's modulus, since the damage induces a decrease of the pad assembly stiffness and therefore of its effective Young's modulus: indeed its variation could be used for diagnostic purposes. The effective Young's modulus can be estimated from the first bending resonance frequency identified from the frequency response function measured on the pad assembly. Two kinds of excitation methods, i.e. conventional impulse excitation and magnetic actuation, will be presented and two different measurement sensors, e.g. laser Doppler vibrometer and microphone, analyzed. The robustness of the effective Young's modulus as a diagnostic feature will be demonstrated in comparison to the first bending resonance frequency, which is more sensitive to geometrical dimensions. Variability in the sample dimension, in fact, will induce a variation of the resonance frequency which could be mistaken for damage. The diagnostic approach has been applied to a set of undamaged and damaged pad assemblies showing good performance in terms of damage identification. The environmental temperature can be an important interfering input for the diagnostic procedure, since it influences the effective Young's modulus of the assembly. For that reason, a test at different temperatures in the range between 15 °C and 30 °C has been performed, evidencing that damage identification technique is efficient at any temperature. The robustness of the Young's modulus as a diagnostic feature with respect to damping is also presented.

    Palmatier and Rovner (2015) suggested that the Preliminary Process Theory (PPT) is a plausible theoretical account for explaining the rationale underlying two major polygraph tests, the Comparison Question Test (CQT) and the Concealed Information Test (CIT). To support their suggestion they claimed that both tests detect deception while relying on orienting responses. This approach is critically discussed. It was concluded that application of current scientific theories to polygraph diagnostic procedures should be done separately for the CIT and for the CQT. Finally, a call was extended for more research on unanswered questions in polygraph testing. PMID:25093905

    Purpose: To analyze the efficacy and impact on management of PET-FDG in patients with metastases from unknown primary tumor.Procedures: Retrospective analysis of 24 patients referred to the PET center for metastasis of unknown primary after a negative imaging workup. PET results were validated by means of oriented imaging, follow-up or biopsy when ethically justified.Results: PET identified the primary tumor in 13/24 (54%) of patients: breast (n = 1), lung (n = 9), colon (n = 1), stomach (n = 1) and mouth (n = 1). The false positive rate of PET was 21% (5/24). PET was shown to affect the management of 10/24 patients (42%).Conclusion: Whole body PET-FDG was more effective than conventional imaging methods in detecting unknown primary tumors. PET altered patient management in 42% of cases. PET should be performed prior to other investigations in such patients and could avoid unnecessary and often unfruitful diagnostic procedures.

    In view of the rapid expansion of diagnostic nuclear medicine procedures in Iran, this study was undertaken to examine trends of nuclear medicine practice in the country and to determine the mean effective dose equivalent per patient and per capita. Comprehensive national data covering 93% of all nuclear medicine centers in 1985-1989 were obtained. The total number of nuclear medicine examinations inc teased by 42% during these years. The relative frequency of thyroid investigations was 84% followed by liver/spleen and bone procedures (7% and 6%, respectively). {sup 99m}Tc was the radionuclide of choice for 86% of investigation while {sup 131}I alone accounted for 59% of collective effective dose equivalent. The annual average number of nuclear medicine procedures per 1,000 people was 1.9. For the thyroid, the highest number (48%) of patients investigated was in the 15-29 y age group and the lowest (3%) was in the >64 y age group. The male to female ratio of thyroid and cardiac patient was 0.18 and 3.64, respectively. The numbers of males and females studied for the remaining eight procedures were less frequent and about the same. The mean effective dose equivalent per patient and per capita was about 4.3 mSv and 8 {mu}Sv, respectively. {sup 131}I was responsible for most of collective effective dose equivalent produced by nuclear medicine. Therefore, future efforts should be concentrated on dose reduction for diagnostic {sup 131}I tests.

    Ross, Julie; Wolf, Debby; Reece, Kimberly

    2014-01-01

    Context: The Joint Commission’s Universal Protocol has been widely implemented in surgical settings since publication in 2003. The elements improved patient safety in operating rooms, and the same rigor is being applied to procedures occurring in other health care arenas, in particular, diagnostic imaging. Objective: In 2011, Kaiser Permanente West Los Angeles’s Diagnostic Imaging Department desired to adapt previous work on Universal Protocol implementation to improve patient safety in interventional radiology and mammography procedures. Design: The teams underwent human factors training and then adapted key interventions used in surgical suites to their workflows. Time-out posters, use of whiteboards, “glitch books,” and regular audits provided structure to overcome the risks that human factors present. Main Outcome Measures: Staff and physician perceptions of the teamwork and safety climates in their modalities were measured using the Safety Attitudes Questionnaire at baseline and at 18 months after training. Unusual Occurrence Reports were also reviewed to identify events and near misses that could be prevented. Implementation of key process changes were identified as process measures. Results: Perception of the safety climate improved 25% in interventional radiology and 4.5% in mammography. Perception of the teamwork climate decreased 5.4% in interventional radiology and 16.6% in mammography. Unusual occurrences were underreported at baseline, and there is ongoing reluctance to document near misses. Conclusion: This work provides important considerations of the impact of departmental cultures for the implementation of the Universal Protocol in procedural areas. It also reveals unexpected challenges, and requires long-term effort and focus. PMID:24626070

    An outbreak of cadmium intoxication in a jewelry factory provided an opportunity for evaluating the usefulness of diagnostic procedures used to evaluate human cadmium toxicity. Blood cadmium levels in workers exposed to cadmium were higher (.93 micrograms/100ml vs .38 micrograms/100 ml) than in unexposed workers. A dose-response relationship was noted between blood cadmium level and symptom prevalence in four symptoms (dyspnea, chest pain, dysuria, and dizziness). Segmental hair analysis revealed highest cadmium levels (up to 19 micrograms/gm) in segments formed prior to cadmium exposure, suggesting that extrinsic contamination was the primary source of cadmium in the hair. beta2-microglobulin levels were within normal limits. No significant renal or pulmonary dysfunction was noted. Symptoms ceased after a cadmium-containing brazing alloy used in jewelry production was replaced, yet urine cadmium levels remained persistently elevated in four workers. Blood cadmium determinations were found to be useful in evaluating symptoms potentially related to cadmium intoxication. PMID:222221

    2013-07-01

    In the field of rolling element bearing diagnostics envelope analysis, and in particular the squared envelope spectrum, have gained in the last years a leading role among the different digital signal processing techniques. The original constraint of constant operating speed has been relaxed thanks to the combination of this technique with the computed order tracking, able to resample signals at constant angular increments. In this way, the field of application of squared envelope spectrum has been extended to cases in which small speed fluctuations occur, maintaining the effectiveness and efficiency that characterize this successful technique. However, the constraint on speed has to be removed completely, making envelope analysis suitable also for speed and load transients, to implement an algorithm valid for all the industrial application. In fact, in many applications, the coincidence of high bearing loads, and therefore high diagnostic capability, with acceleration-deceleration phases represents a further incentive in this direction. This paper is aimed at providing and testing a procedure for the application of envelope analysis to speed transients. The effect of load variation on the proposed technique will be also qualitatively addressed.

    Background Breast-conserving surgery (BCS) is the most common treatment for ductal carcinoma in situ (DCIS); however, how often women experience subsequent diagnostic evaluations over time is not known. Methods We identified 2948 women with DCIS who were treated with BCS from 1990 to 2001 and followed for up to 10 years at three integrated health-care delivery systems. We calculated the percentages of diagnostic mammograms and ipsilateral invasive procedures following the initial breast excision to treat DCIS, estimated the 10-year cumulative incidence of these procedures, and determined hazard ratios for both types of procedures with Cox regression modeling. All statistical tests were two-sided. Results Over 10 years, 907 women (30.8%) had 1422 diagnostic mammograms and 1813 (61.5%) had 2305 ipsilateral invasive procedures. Diagnostic mammograms occurred in 7.3% of women in the first 6 months and continued at a median annual rate of 4.3%. Ipsilateral invasive procedures occurred in 51.5% of women in the first 6 months and continued at a median annual rate of 3.1%. The estimated 10-year cumulative risk of having at least one diagnostic mammogram after initial DCIS excision was 41.0% (95% confidence interval [CI] = 38.5% to 43.5%); at least one invasive procedure, 65.7% (95% CI = 63.7% to 67.8%); and either event, 76.1% (95% CI = 74.1% to 78.1%). Excluding events in the first 6 months following initial DCIS excision, corresponding risks were 36.4% (95% CI = 33.8% to 39.0%) for diagnostic mammograms, 30.4% (95% CI = 26.9% to 33.8%) for invasive procedures, and 49.5% (95% CI = 45.6% to 53.5%) for either event. Conclusions Women with DCIS treated with BCS continue to have diagnostic and invasive breast procedures in the conserved breast over an extended period. The frequency of ongoing diagnostic breast evaluations should be included in discussions about treatment. PMID:22491230

    Monitoring complications and diagnostic yield for image-guided procedures is an important component of maintaining high quality patient care promoted by professional societies in radiology and accreditation organizations such as the American College of Radiology (ACR) and Joint Commission. These outcome metrics can be used as part of a comprehensive quality assurance/quality improvement program to reduce variation in clinical practice, provide opportunities to engage in practice quality improvement, and contribute to developing national benchmarks and standards. The purpose of this article is to describe the development and successful implementation of an automated web-based software application to monitor procedural outcomes for US- and CT-guided procedures in an academic radiology department. The open source tools PHP: Hypertext Preprocessor (PHP) and MySQL were used to extract relevant procedural information from the Radiology Information System (RIS), auto-populate the procedure log database, and develop a user interface that generates real-time reports of complication rates and diagnostic yield by site and by operator. Utilizing structured radiology report templates resulted in significantly improved accuracy of information auto-populated from radiology reports, as well as greater compliance with manual data entry. An automated web-based procedure log database is an effective tool to reliably track complication rates and diagnostic yield for US- and CT-guided procedures performed in a radiology department.

    OBJECTIVES. This study sought to examine racial differences in the use of medical procedures and diagnostic tests by elderly Americans. METHODS. We used 1986 physician claims data for a 5% national sample of Medicare enrollees aged 65 years and older to study 32 procedures and tests. For each service, we calculated the age- and sex-adjusted rate of use by race and the corresponding White-Black relative risk. RESULTS. Whites were more likely than Blacks to receive 23 services, and for many of these services, the differences in use were substantial. In contrast, Blacks were more likely than Whites to receive seven services. Whites had a particular advantage in access to higher-technology or newer services. Racial differences in use persisted among elders who had Medicaid in addition to Medicare coverage and increased among rural elders. CONCLUSIONS. There are pervasive racial differences in the use of medical services by elderly Americans that cannot be explained by differences in the prevalence of specific clinical conditions. Financial barriers to care do not fully account for these findings. Race may exacerbate the impact of other barriers to access. PMID:8328615

    Cognitive and procedural skills required of cardiologists have increased in the past 10 years. What is unknown is whether residents consistently meet recommended volumes during training and what their own subjective assessments of their competency are after training. The purpose of this study was to (1) determine whether current training provides residents with opportunities to develop skills to function independently and (2) identify whether residents perceive gaps in their skills. We surveyed current and recent graduates of adult cardiology programs in Canada. One hundred ten responses from 425 surveys were received. Procedural and diagnostic test interpretation volumes were recorded, as were the optimum number the respondents believed were important to complete to function independently. These volumes were compared with the 2008 American College of Cardiology Core Cardiology Training Symposium (COCATS 3) and the Canadian Cardiovascular Society (CCS) recommendations for training. The proportion of residents meeting recommended volumes for diagnostic test interpretation ranged from 7% (Holter monitors) to 91% (echocardiograms). For procedures, the range was from 71% (echocardiography) to 100% (cardioversion). The ratio of residents' perceived minimum numbers believed to be required for proficiency for diagnostic test interpretation to those recommended ranged from 14% (electrocardiograms) to 116% (echocardiograms), and for procedures, the ratio was 66% (temporary pacemaker placement) to 116% (echocardiography). Recent graduates' perception of minimum required numbers to achieve competency is underestimated compared with COCATS 3 and CCS recommendations. Few graduates achieved the recommended volume targets suggested for diagnostic test interpretation. PMID:25547557

    The general task of abduction is to infer a hypothesis that best explains a set of data. A typical subtask of this is to synthesize a composite hypothesis that best explains the entire data from elementary hypotheses which can explain portions of it. The synthesis subtask of abduction is computationally expensive, more so in the presence of certain types of

    Therapeutic or diagnostic radiopharmaceutical capsule containing Na131I stays in stomach for 15 minutes before the absorption starts, long enough to make possible risky exposure. During the oral application it is reasonable to measure effective dose in stomach. Direct measurements of organ doses are not possible so there is a strong recommendation to estimate them by calculation. The main goal is the 131I risk assessment. Monte Carlo code MCNP4b was used to model the transport of gamma and beta particles emitted by radionuclide 131I considered as a point source at the bottom of the stomach. Absorbed energy per unit transformation in stomach and surrounding organs has been calculated. The dose equivalents in these organs have been calculated in aim to determine the effective doses using appropriate tissue weighting factor values. Obtained results had not significant importance for radiation protection but they were important for establishment of new calibration procedures as a part of QA and QC programs in radiopharmaceuticals production and control.

    Background Infravesical obstruction leads to kidney and bladder dysfunction in a significant proportion of boys. The aim of this review is to determine the value of diagnostic tests for ascertainment of infravesical obstruction in boys. Methodology We searched PubMed and EMBASE databases until January 1, 2013, to identify papers that described original diagnostic accuracy research for infravesical obstruction in boys. We extracted information on (1) patient characteristics and clinical presentation of PUV and (2) diagnostic pathway, (3) diagnostic accuracy measures and (4) assessed risk of bias. Principal Findings We retrieved 15 studies describing various diagnostic pathways in 1,189 boys suspected for infravesical obstruction. The included studies reflect a broad clinical spectrum of patients, but all failed to present a standardised approach to confirm the presence and severity of obstruction. The risk of bias of included studies is rather high due to work-up bias and missing data. Conclusions As a consequence of low quality of methods of the available studies we put little confidence in the reported estimates for the diagnostic accuracy of US, VCUG and new additional tests for ruling in or ruling out infravesical obstruction. To date, firm evidence to support common diagnostic pathways is lacking. Hence, we are unable to draw conclusions on diagnostic accuracy of tests for infravesical obstruction. In order to be able to standardise the diagnostic pathway for infravesical obstruction, adequate design and transparent reporting is mandatory. PMID:24586242

    Tarlov or perineural cysts are lesions of the nerve root most often found in the sacral region. Several authors recommend surgical treatment of symptomatic Tarlov cysts. However, successful surgical treatment is dependent on appropriate patient selection. In this article, we report three cases of a sacral perineural cyst, causing sciatic pain, and emphasize the usefulness of CT-guided percutaneous aspiration as an important diagnostic and prognostic procedure prior to definitive operative treatment.

    2006-01-01

    Background In 1998 a formal process using the criteria of safety, effectiveness and cost-effectiveness (evidence based medicine) on the introduction and use of new medical procedures was implemented in Australia. As part of this process an expert panel, the Medical Services Advisory Committee (MSAC) was set up. This paper examines the effectiveness of this process based on the original criteria, that is, evidence based medicine. Method The data for this analysis was sourced primarily from that made available in the public domain. The MSAC web site provided Minutes from MSAC meetings; Annual Reports; Assessment and Review reports; Progress status; and Archived material. Results The total number of applications submitted to the MSAC has been relatively low averaging approximately only fourteen per year. Additionally, the source of applications has quickly shifted to the medical devices, equipment and diagnostic industry as being the major source of applications. An overall average time for the processing of an application is eighteen months. Negative recommendations were in most cases based on insufficient clinical evidence rather than clinical evidence that clearly demonstrated a lack of clinical effectiveness. It was rare for a recommendation, either positive or negative, to be based on cost-effectiveness. Conclusion New medical procedures are often the result of a process of experimentation rather than formally conducted research. Affordability and the question of who should pay for the generation, collection and analysis of the clinical evidence is perhaps the most difficult to answer. This is especially the case where the new procedure is the result of a process of experimentation with an old procedure. A cost-effective way needs to be found to collect acceptable levels of evidence proving the clinical effectiveness of these new procedures, otherwise the formal processes of evaluation such as that used by the Australian MSAC since 1998 will continue to run the risk of committing Type II errors, that is, denying access to medical procedures that are beneficial and efficient.

    The PERT is a SPR (Reticular Programation System) based on statistic-mathematic models. Since some years they are applied to productive processes to increase the efficiency and effectiveness. They all have a same base structure which is the net that is composed by the logical succession of the event and the activity which has the part of the project. Determining the minimum time (to), the maximum one (tp) and the more frequent time (tm) of each activity and applying the statistic method PERT, one gets the probable duration (te) of every activity and the critical path of the net is placed in evidence. This is formed by the chain of those activities whose duration determines the total duration of the project. The Authors have desired to verify the applicability of SPR even to the "medical industry" and, more precisely, to the diagnostic process for the verification of radiculoneuropathy. Such pathology affects a large part of the active population. The diagnostic process in this case comprises besides an accurate neurological and clinical examination of the patient, also the x-ray exam, the electromyography, the Computed Tomography (CT) and the Magnetic Resonance Imaging (MR) exam. These last two investigations gives an increase of diagnostic accuracy. With the collaboration of the physicians of the diagnostic Service, the Authors have measured in every step of the diagnostic procedure the waiting time of 48 patients with low back pain. Applying the PERT method, it has been possible to put in evidence in the net the critical activities. They are such that their duration time determines the probable duration of the whole diagnostic process. Such duration in this case it corresponds to 91 days with a standard deviation of 33 days. The delay of any critical activity causes a lealy of the whole route. This delay influences negatively on the patient's health. Besides it determines an economic damage to the system because a relation cost/time exists. The systems of reticular programmation have as objective not only the one of improving the programmation and the control of the processes, but also the attainment of an optimum cost/time ratio, varying in a way that the total cost of the realization of the process is minimum. They represent a useful criterion to direct Quality Assurance (Q.A) in the local political sanitary context, within the bounds of organization of technical - scientific quality. An accurate application of the Q.A. should modify besides the duration of the critical activities. PMID:2483632

    Objective: The purpose of this study was to determine if diagnostic and therapeutic procedures for the cervical and cranial spine taught to students during the undergraduate program at Canadian Memorial Chiropractic College are required to be used during their internship by their supervising clinicians and, if so, to what extent these procedures are used. Methods: Course manuals and course syllabi from the Applied Chiropractic and Clinical Diagnosis faculty of the undergraduate chiropractic program for the academic year 2009–2010 were consulted and a list of all diagnostic and therapeutic procedures for the cranial and cervical spine was compiled. This survey asked clinicians to indicate if they themselves used or if they required the students they were supervising to use each procedure listed and, if so, to what extent each procedure was used. Demographic information of each clinician was also obtained. Results: In general, most diagnostic procedures of the head and neck were seldom used, with the exception of postural observation and palpation. By contrast, most cervical orthopaedic tests were often used, with the exception of tests for vertigo. Most therapeutic procedures were used frequently with the exception of prone cervical and “muscle” adjustments. Conclusion: There was a low degree of vertical integration for cranial procedures as compared to a much higher degree of vertical integration for cervical procedures between the undergraduate and clinical internship programs taught. Vertical integration is an important element of curricular planning and these results may be helpful to aid educators to more appropriately allocate classroom instruction PMID:22778531

    Objective To study the diagnostic and treatment modalities used in drug allergy/hypersensitivity among members of the World Allergy Organization (WAO). Methods A questionnaire comprising 39 questions was circulated electronically to member societies, associate member societies, and regional and affiliate organizations of WAO between June 29, 2009, and August 9, 2009. Results Eighty-two responses were received. Skin testing was used by 74.7%, with only 71.4% having access to penicillin skin test reagents. In vitro–specific IgE tests were used by 67.4%, and basophil activation test was used by 54.4%. Lymphocyte transformation tests were used by 36.8% and patch tests by 54.7%. Drug provocation tests were used by 68.4%, the most common indication being to exclude hypersensitivity where history/symptoms were not suggestive of drug hypersensitivity/allergy (76.9%). Rapid desensitization for chemotherapy, antibiotics, or biologic agents was used by 69.6%. Systemic corticosteroid was used in the treatment of Stevens–Johnson syndrome by 72.3%, and high-dose intravenous immunoglobulins in toxic epidermal necrolysis by 50.8%. Human leukocyte antigen screening before prescription of abacavir was used by 92.9% and before prescription of carbamazepine by 21.4%. Conclusions Results of this survey form a useful framework for developing educational and training needs and for improving access to drug allergy diagnostic and treatment modalities across WAO member societies.

    Quality control of brake pads is an important issue, being the pad a key component of the braking system. Since the pad - backing plate detachment can alter the mechanical properties of the whole system, the Young Modulus variation could be used for diagnostic purposes, it being a symptom of that impelling damage. The Young Modulus will be estimated from the first bending resonance frequency which will be identified from the Frequency Response Function measured on the pad. Two kind of excitation methods, i.e. impact hammer and magnetic actuation, will be presented and two different measurement sensors, e.g. Laser Doppler Vibrometry and microphone, analysed. A comparison with standard non-contact ultrasonic measurement on a simple isotropic and homogenous aluminium test sample is presented to validate the approach.

    The goal of this study was to improve assessment of diagnostic measures for lateral localization of aldosterone-producing adrenal adenomas preparatory to retroperitoneoscopic removal, in view of the fact that this technique allows for only unilateral access. A retrospective study was carried out of the medical records of 64 patients (38 women, 26 men, average age 46.8+/-11.2) who underwent surgery at University Hospital, Münster, between 1969 and 1998. Seventeen of the 64 patients presented with hyperplasia and 47 had adrenal adenoma. In cases of hyperplasia, computerized tomography imaged a false-positive unilateral tumor 10 times, a false-negative 3 times, and a unilateral hyperplasia 1 time (ultrasonography: tumor 2 times, false-negative 3 times; 131I-Iodomethylnorcholesterol scintigraphy: tumor 5 times, false-negative 1 time, correct 1 time). In cases of adenoma, computerized tomography yielded accurate results 40 times, imaged a false-negative 2 times, and indicated the incorrect side 1 time (Ultrasonography: false-negative 12 times, correct side 9 times, incorrect side 1 time; 131I-Iodomethylnorcholesterol scintigraphy: correct side 19 times, false-positive (both sides) 5 times, negative 3 times, incorrect side 2 times). Venous sampling, which was carried out seven times, yielded accurate results six times, and failed technically one time. Venous sampling appears to be the method of choice for preoperative lateral localization. Thus, retroperitoneoscopic treatment of Conn's syndrome should not be carried out unless venous sampling is carried out first. PMID:11228039

    In the upper respiratory tract, a new endoscopic procedure with ultra-thin and miniature fiberoptics (290 micrometers - 2 mm) finds a wide range of application in the differential diagnosis and treatment of pathological changes, especially within the nasal cavities and the paranasal sinuses. In order to restore the normal condition of ventilation and drainage of the paranasal sinuses or to remove internal inflammation the given foramina or ducts are widened mechanically. In case of the ostium nasomaxillaris `anatomical landmarks' can be used for orientation. But in case of the ostium nasofrontalis ((theta) 1 - 3 mm) or revision surgery where the anatomical conditions are not definitely defined or totally changed, problems can occur due to a lack of orientation. Dangerous complications which can occur due to surgical disorientation are the injury of the optic nerve and the dura mater. This paper presents an endoscopic variation of the infrared idaphanoscopy (IRD), a band-limited cw transillumination method, which enables localization of the foramina or ducts during the endoscopic procedure resulting in a reduction in the risk of disorientation.

    Abduction, or inference to a best explanation, is a ubiquitous type of inference that is frequently used by humans in a wide range of tasks. However, many realistic domains have properties that make abduction computationally intractable (i.e., where the time to reach a solution increases exponentially with the number of possible explanations). We present a domain task analysis and performance evaluation of RedSoar, a plausible cognitive computational model of abduction, that accomplishes the antibody identification task in immunohematology. The task analysis reveals how a computationally intractable abductive problem, where one is seeking optimal solutions, can be reformulated to be a computationally tractable abductive problem, by seeking satisfactory rather then optimal solutions. From the satisfactory perspective, our evaluation framework of RedSoar's performance explores the computational benefits and costs of having directly available abstract hypothesis formation knowledge, and how a strong causal constraint between hypotheses and data reduces the combinatorial explosion of constructing a best explanation.

    Authored and researched by individuals who work for the Human Rights Watch Organization, this 31-page report documents the tragic situation faced by children in Uganda. Since 1986, members of the Lord's Resistance Army in northern Uganda have abducted close to 20,000 children, often forcing them to serve as soldiers, laborers, and sexual slaves. The report estimates that since June of 2002, almost 5,000 children have been abducted. The report is based on field research conducted in February 2003, and includes interviews with eighteen children (who are now young adults), and a number of religious and civic leaders. The authors of the report have divided the work into six primary sections, including a summary of their findings, policy recommendations, background material, and documentation of how the children are recruited into the LRA.

    Data on occupational radiation exposure from nuclear medicine procedures for the time period of the 1950s through the 1970s is important for retrospective health risk studies of medical personnel who conducted those activities. However, limited information is available on occupational exposure received by physicians and technologists who performed nuclear medicine procedures during those years. To better understand and characterize historical radiation exposures to technologists, the authors collected information on nuclear medicine practices in the 1950s, 1960s, and 1970s. To collect historical data needed to reconstruct doses to technologists, a focus group interview was held with experts who began using radioisotopes in medicine in the 1950s and the 1960s. Typical protocols and descriptions of clinical practices of diagnostic radioisotope procedures were defined by the focus group and were used to estimate occupational doses received by personnel, per nuclear medicine procedure, conducted in the 1950s to 1960s using radiopharmaceuticals available at that time. The radionuclide activities in the organs of the reference patient were calculated using the biokinetic models described in ICRP Publication 53. Air kerma rates as a function of distance from a reference patient were calculated by Monte Carlo radiation transport calculations using a hybrid computational phantom. Estimates of occupational doses to nuclear medicine technologists per procedure were found to vary from less than 0.01 ?Sv (thyroid scan with 1.85 MBq of administered I-iodide) to 0.4 ?Sv (brain scan with 26 MBq of Hg-chlormerodin). Occupational doses for the same diagnostic procedures starting in the mid-1960s but using Tc were also estimated. The doses estimated in this study show that the introduction of Tc resulted in an increase in occupational doses per procedure. PMID:25162420

    Purpose: The objective of this study was to determine to what extent the diagnostic and therapeutic procedures taught in the undergraduate program used for patients with lumbopelvic conditions are expected to be utilized by students during their clinical internship program at Canadian Memorial Chiropractic College or are being used by the clinical faculty. Methods: A confidential survey was distributed to clinical faculty at the college. It consisted of a list of diagnostic and therapeutic procedures used for lumbopelvic conditions taught at that college. Clinicians were asked to indicate the frequency with which they performed or they required students to perform each item. Results: Seventeen of 23 clinicians responded. The following procedures were most likely required to be performed by clinicians: posture; ranges of motion; lower limb sensory, motor, and reflex testing; and core orthopedic tests. The following were less likely to be required to be performed: Waddell testing, Schober's test, Gillet tests, and abdominal palpation. Students were expected to perform (or clinicians performed) most of the mobilization (in particular, iliocostal, iliotransverse, and iliofemoral) and spinal manipulative therapies (in particular, the procedures referred to as the lumbar roll, lumbar pull/hook, and upper sacroiliac) taught at the college. Conclusion: This study suggests that there was considerable, but not complete, vertical integration between the undergraduate and clinical education program at this college. PMID:20480014

    Introduction. Use of Pavlik harness for the treatment of DDH can be complicated for parents. Any misuse or failure in the adjustments may lead to significant complications. An abduction brace was introduced in our institution, as it was thought to be easier to use. Aim. We assess the results for the treatment of DDH using our abduction brace in children of 0–6 months old and compare these results with data on treatments using the Pavlik harness. Method. Retrospective analysis of patients with DDH from 0 to 6 months old at diagnosis, performed from 2004 to 2009. Outcomes were rates of reduction of the hip and avascular necrosis of the femoral head (AVN). Follow-up was at one year and up to 4 years old. Results. Hip reduction was successful in 28 of 33 patients (85%), with no AVN. Conclusion. Our results in terms of hip reduction rate and AVN rate are similar to those found in literature assessing Pavlik harness use, with a simpler and comfortable treatment procedure. PMID:25815214

    Why do mouse corneal epithelial cells display spiraling patterns? We want to provide an explanation for this curious phenomenon by applying an idealized problem solving process. Specifically, we applied complementary line-fitting methods to measure transgenic epithelial reporter expression arrangements displayed on three mature, live enucleated globes to clarify the problem. Two prominent logarithmic curves were discovered, one of which displayed the ? ratio, an indicator of an optimal configuration in phyllotactic systems. We then utilized two different computational approaches to expose our current understanding of the behavior. In one procedure, which involved an isotropic mechanics-based finite element method, we successfully produced logarithmic spiral curves of maximum shear strain based pathlines but computed dimensions displayed pitch angles of 35° (? spiral is ?17°), which was altered when we fitted the model with published measurements of coarse collagen orientations. We then used model-based reasoning in context of Peircean abduction to select a working hypothesis. Our work serves as a concise example of applying a scientific habit of mind and illustrates nuances of executing a common method to doing integrative science. © 2014 Wiley Periodicals, Inc.

  19. Sleep paralysis, sexual abuse, and space alien abduction.

    McNally, Richard J; Clancy, Susan A

    2005-03-01

    Sleep paralysis accompanied by hypnopompic ('upon awakening') hallucinations is an often-frightening manifestation of discordance between the cognitive/perceptual and motor aspects of rapid eye movement (REM) sleep. Awakening sleepers become aware of an inability to move, and sometimes experience intrusion of dream mentation into waking consciousness (e.g. seeing intruders in the bedroom). In this article, we summarize two studies. In the first study, we assessed 10 individuals who reported abduction by space aliens and whose claims were linked to apparent episodes of sleep paralysis during which hypnopompic hallucinations were interpreted as alien beings. In the second study, adults reporting repressed, recovered, or continuous memories of childhood sexual abuse more often reported sleep paralysis than did a control group. Among the 31 reporting sleep paralysis, only one person linked it to abuse memories. This person was among the six recovered memory participants who reported sleep paralysis (i.e. 17% rate of interpreting it as abuse-related). People rely on personally plausible cultural narratives to interpret these otherwise baffling sleep paralysis episodes. PMID:15881271

  20. In-vivo glenohumeral translation and ligament elongation during abduction and abduction with internal and external rotation

    Study Design Basic Science. To investigate humeral head translations and glenohumeral ligament elongation with a dual fluoroscopic imaging system. Background The glenohumeral ligaments are partially responsible for restraining the humeral head during the extremes of shoulder motion. However, in-vivo glenohumeral ligaments elongation patterns have yet to be determined. Therefore, the objectives of this study were to 1) quantify the in-vivo humeral head translations and glenohumeral ligament elongations during functional shoulder positions, 2) compare the inferred glenohumeral ligament functions with previous literature and 3) create a baseline data of healthy adult shoulder glenohumeral ligament lengths as controls for future studies. Methods Five healthy adult shoulders were studied with a validated dual fluoroscopic imaging system (DFIS) and MR imaging technique. Humeral head translations and the superior, middle and inferior glenohumeral ligaments (SGHL, MGHL, IGHL) elongations were determined. Results The humeral head center on average translated in a range of 6.0mm in the anterior-posterior direction and 2.5mm in the superior-inferior direction. The MGHL showed greater elongation over a broader range of shoulder motion than the SGHL. The anterior-band (AB)-IGHL showed maximum elongation at 90° abduction with maximum external rotation. The posterior-band (PB)-IGHL showed maximum elongation at 90° abduction with maximum internal rotation. Discussion The results demonstrated that the humeral head translated statistically more in the anterior-posterior direction than the superior-inferior direction (p?=?0.01), which supports the concept that glenohumeral kinematics are not ball-in-socket mechanics. The AB-IGHL elongation pattern makes it an important static structure to restrain anterior subluxation of the humeral head during the externally rotated cocking phase of throwing motion. These data suggest that in healthy adult shoulders the ligamentous structures of the glenohumeral joint are not fully elongated in many shoulder positions, but function as restraints at the extremes of glenohumeral motion. Clinically, these results may be helpful in restoring ligament anatomy during the treatment of anterior instability of the shoulder. PMID:22741601

    Background The diagnostic performance of endoscopic and microscopic procedures for detecting diseases of the middle ear in patients with chronic otitis media (COM) has rarely been investigated. This study was conducted to compare the performance of these procedures for identifying middle ear structures and their associated diseases in COM patients. Methods In this prospective cohort study, 58 patients with chronic COM, who were candidates for tympanoplasty with or without a mastoidectomy, were enrolled. Before the surgical intervention, the middle ear was examined via an operating microscope and then through an endoscope to identify the middle ear structures as well as diseases associated with the middle ear. Results The patients were 15 years of age or older. The anatomical parts of the middle ear – the epitympanic, posterior mesotympanic, and hypotympanic structures – were more visible through an endoscope than through a microscope. In addition, the various segments of the mesotympanum, oval window, round window, and Eustachian tube were more visible via endoscopy. The post-operative endoscopic reevaluation of the middle ear revealed that a cholesteatoma had remained in four of 13 patients after surgery. Conclusion According to the results of this study, in cases in which there is poor visibility with the operating microscope or the surgeon suspects remaining disease within the middle ear, endoscopy could be utilized to improve the evaluation of more hidden middle ear pits and structures, particularly if there is a potentially recrudescent pathology.

  2. A three-dimensional model of vocal fold abductionÕadduction

    2006-01-01

    A three-dimensional biomechanical model of tissue deformation was developed to simulate dynamic vocal fold abduction and adduction. The model was made of 1721 nearly incompressible finite elements. The cricoarytenoid joint was modeled as a rocking–sliding motion, similar to two concentric cylinders. The vocal ligament and the thyroarytenoid muscle’s fiber characteristics were implemented as a fiber–gel composite made of an isotropic ground substance imbedded with fibers. These fibers had contractile and/or passive nonlinear stress–strain characteristics. The verification of the model was made by comparing the range and speed of motion to published vocal fold kinematic data. The model simulated abduction to a maximum glottal angle of about 31°. Using the posterior-cricoarytenoid muscle, the model produced an angular abduction speed of 405° per second. The system mechanics seemed to favor abduction over adduction in both peak speed and response time, even when all intrinsic muscle properties were kept identical. The model also verified the notion that the vocalis and muscularis portions of the thyroarytenoid muscle play significantly different roles in posturing, with the muscularis portion having the larger effect on arytenoid movement. Other insights into the mechanisms of abduction/adduction were given. PMID:15101653

    [Purpose] The purpose of this study was to determine the changes in the supraspinatus cross-sectional areas according to shoulder abduction angles, using ultrasonography. [Subjects and Methods] The subjects consisted of 40 individuals (20 males and 20 females). The cross-sectional areas of the supraspinatus of all subjects were measured with ultrasonography at abduction angle of 0°, 30°, 60°, 90°, and 120°. We set four abduction angle levels (I, II, III, and IV), 0° to 30°, 30° to 60°, 60° to 90°, and 90° to 120°, respectively, when determining the largest change in cross-sectional area. [Results] The results revealed that cross-sectional areas of the supraspinatus increased at all levels, but the abduction angle level with the largest increase in cross-sectional area of the supraspinatus was Level III. [Conclusion] The above results indicate that performing exercises at an abduction angle between 60° and 90° will be the most effective for supraspinatus strengthening in clinical practice.

  6. Not without a fair fight: failed abductions of females in wild hamadryas baboons.

    PubMed

    Pines, Mathew; Swedell, Larissa

    2011-07-01

    In contrast to other papionin monkeys, hamadryas baboons are characterized by female-biased dispersal. Given that hamadryas females do not disperse voluntarily, one mechanism for female transfer between bands is thought to be abductions during aggressive intergroup conflict. To date, however, no successful abductions have been witnessed. We describe three abduction events at the Filoha field site in Ethiopia, two interband and one intraband, in which the abductors successfully separated a female from her leader male for several minutes or hours. In each case, the original leader male located the abductor and retrieved the female, even if it involved entering the social sphere of another band. These observations suggest that a hamadryas leader male will risk injury and loss of additional females in his attempt to retrieve a female from an abductor unless the abductor has openly challenged the leader for possession of his female and physically defeated him.

    2014-08-01

    Children affected by infantile esotropia can cross-fixate to see object to the contralateral side with the adducted eye; when doing so they need not abduct the eye ipsilateral to the object and thus can appear to have abduction defects. Less commonly, an esotropic child is truly unable to abduct and cross-fixates to allow side gaze. We report the case of a 10-month-old girl with cross-fixation and inability to abduct who was genetically proven to have horizontal gaze palsy with progressive scoliosis (recessive ROBO3 mutations). Clinical assessment of her elder brother, previously diagnosed with bilateral type 3 Duane retraction syndrome, revealed that he was actually affected by the same disease. We highlight this rare ocular motility disorder as part of the differential diagnosis of early childhood esotropia with cross-fixation and inability to abduct and how examination of an affected sibling can facilitate proper diagnosis of genetic eye disease.

    Background To address the risks of adverse pregnancy outcomes and future type 2 diabetes associated with gestational diabetes mellitus (GDM), its early detection and timely treatment is essential. In the absence of an international consensus, multiple different guidelines on screening and diagnosis of GDM have existed for a long time. This may be changing with the publication of the recommendations by the International Association of Diabetes and Pregnancy Study Groups. However, none of these guidelines take into account evidence from or ground realities of resource-poor settings. Objective This study aimed to investigate whether GDM projects supported by the World Diabetes Foundation in developing countries utilize any of the internationally recommended guidelines for screening and diagnosis of GDM, explore experiences on applicability and usefulness of the guidelines and barriers if any, in implementing the guidelines. These projects have reached out to thousands of pregnant women through capacity building and improvement of access to GDM screening and diagnosis in the developing world and therefore provide a rich field experience on the applicability of the guidelines in resource-poor settings. Design A mixed methods approach using questionnaires and interviews was utilised to review 11 GDM projects. Two projects were conducted by the same partner; interviews were conducted in person or via phone by the first author with nine project partners and one responded via email. The interviews were analysed using content analysis. Results The projects use seven different screening procedures and diagnostic criteria and many do not completely adhere to one guideline alone. Various challenges in adhering to the recommendations emerged in the interviews, including problems with screening women during the recommended time period, applicability of some of the listed risk factors used for (pre-)screening, difficulties with reaching women for testing in the fasting state, time consuming nature of the tests, intolerance to high glucose load due to nausea, need for repeat tests, issues with scarcity of test consumables and lack of equipment making some procedures impossible to follow. Conclusion Though an international consensus on screening and diagnosis for GDM is welcome, it should ensure that the recommendations take into account feasibility and applicability in low resource settings to ensure wider usage. We need to move away from purely academic discussions focusing on sensitivity and specificity to also include what can actually be done at the basic care level. PMID:22855644

    Background Severe cases of cubital tunnel syndrome do not always result in functional recovery after surgical decompression of the ulnar nerve. A combined operation of tendon transfer to restore index finger abduction and decompression of the ulnar nerve was performed for patients with severe cubital tunnel syndrome who required powerful pinch strength and whose preoperative compound muscle action potential of the abductor digiti minimi muscle was not recordable or almost non-recordable. The purpose of this study was to assess the efficacy of tendon transfer to restore index finger abduction for severe cubital tunnel syndrome. Methods Sixteen hands in 15 patients with severe cubital tunnel syndrome were operated on with extensor pollicis brevis tendon transfer to the first dorsal interosseous muscle to restore index finger abduction and ulnar nerve decompression. They were reviewed after a mean follow-up of 16 months. All 16 hands had preoperatively severe lesions with paralysis of ulnar intrinsics, marked anaesthesia, or hypaesthesia. Results Postoperative results were excellent in 2 hands, good in 10, fair in 4, and no cases with poor results according to Akahori's criteria. Four hands with fair results had a residual Froment sign or annoying hypaesthesia in the ring and little fingers. All patients were relieved of preoperative discomfort and showed recovery of motor and sensory function. The mean pre- and postoperative pinch strength was 3.3 kg and 5.6 kg, respectively, which showed a significant difference (P<0.01). Mean time of showing a negative Froment sign after surgery was 5 months in 13 cases. Conclusions The extensor pollicis brevis tendon transfer is simple and useful to restore index finger abduction and pinch strength for severe cubital tunnel syndrome. PMID:19396696

    The formation of bonds between strangers is an event that occurs routinely in many social animals, including humans, and, as social bonds in general, they affect the individuals' welfare and biological fitness. The present study was motivated by an interest in the behavioural processes that drive bond formation in a social context of hostility, in which the incumbent partners vary greatly in physical power and reproductive interests, a situation in which individuals of many group-living species find themselves often throughout their lives. We focused on the quantitative analysis of female abductions via male aggressive herding in a nonhuman primate, the hamadryas baboon, in which intersexual bonds are known to be strong. We tested three hypotheses informed by sexual conflict/sexual coercion theory (male herding-as-conditioning and female grooming-as-appeasement) and by socioecological theory (unit size and female competition). The results supported the predictions: males resorted to coercive tactics (aggressive herding) with abducted females, and abducted females elevated the amount of grooming directed at their new unit males; in fact, they escaped from the otherwise negative effect of unit size on female-to-male grooming. These findings reveal that conflicts of interest are natural ingredients underpinning social bonds and that resorting to coercive aggression may be an option especially when partners differ greatly in their physical power.

    [Purpose] This study investigated the effect of hip position on muscle onset time during prone hip extension with knee flexion. [Subjects] The study included 21 healthy male volunteers. [Methods] Muscle onset times of the right gluteus maximus, right hamstrings, bilateral lumbar erector spinae, and bilateral lumbar multifidus were measured using surface electromyography during right hip extension with knee flexion in the prone position. Measurements were made with the hip in 3 positions: (1) neutral, (2) abduction, and (3) abduction and external rotation. [Results] Gluteus maximus onset relative to the hamstrings was significantly earlier with hip abduction and with hip abduction and external rotation compared with that with the hip in the neutral position. Gluteus maximus onset relative to the hamstrings was significantly earlier with hip abduction and external rotation compared with that with hip abduction. The bilateral multifidus and left lumbar erector spinae onset times relative to the hamstrings were significantly earlier with hip abduction and external rotation compared with those with hip abduction and with the hip in the neutral position. [Conclusion] Abduction and external rotation of the hip during prone hip extension with knee flexion is effective for advancing the onset times of the gluteus maximus, bilateral multifidus, and contralateral lumbar erector spinae.

    Trapezius muscle paralysis results from injury to the spinal accessory nerve. Impairment in the trapezius muscle function may destabilize the muscle resulting in winged scapula. A 25-year-old university student who was active in sports had complaints of shoulder drop and pain on abduction. He had a three-year history of fall resulting in a scapular fracture for which he received conservative treatment. Physical examination showed asymmetry and drop of the right shoulder. Lateral scapular winging was apparent particularly above 90 degrees of abduction. Electromyography revealed isolated paralysis of the trapezius muscle. The patient underwent reconstruction with the modified Eden-Lange procedure. After a two-year follow-up, asymmetry in the shoulder decreased, there was no pain on active abduction, and the patient returned to active sports and was fully satisfied with the outcome.

    [Purpose] This study evaluated the effects of bridge exercise on trunk core muscle activity with respect to sling height and hip joint abduction and adduction. [Subjects] Fifteen healthy adult males participated. [Methods] In the bridge exercise, the height of the sling was set low or high during hip joint abduction and adduction. Electromyography was used to compare the differences between the muscle activities of the transverse abdominis, rectus abdominis, and erector spinae muscles. [Results] The muscle activities of the transverse abdominis, rectus abdominis, and erector spinae were significantly higher in the high sling position. Furthermore, the activities of the transverse abdominis and erector spinae were significantly higher during hip joint adduction than abduction regardless of sling height. [Conclusion] A high sling height is the most effective intervention for increasing the muscle activities of the transverse abdominis and erector spinae muscles during hip joint adduction in a bridge exercise.

    The degree of hallux abduction in extant and fossil hominoids is analysed in terms of geometric relationships between the first metatarsal and the medial cuneiform and quantified by angular data, in relation to grasping ability and locomotor pattern. The 'australopithecine' pattern corresponds to an abducted first podal ray with some grasping abilities and seems to be derived from a ' Proconsul-like' pattern rather than a 'living African great ape-like' pattern. The Olduvai Hominid 8 condition closely resembles that of the modern human which corresponds to a full bipedalism.

    Background and Purpose Stiff-knee gait is defined as reduced knee flexion during the swing phase. It is accompanied by frontal plane compensatory movements (eg, circumduction and hip hiking) typically thought to result from reduced toe clearance. As such, we examined if knee flexion assistance before foot-off would reduce exaggerated frontal plane movements in people with stiff-knee gait after stroke. Methods We used a robotic knee orthosis to assist knee flexion torque during the preswing phase in 9 chronic stroke subjects with stiff-knee gait on a treadmill and compared peak knee flexion, hip abduction, and pelvic obliquity angles with 5 nondisabled control subjects. Results Maximum knee flexion angle significantly increased in both groups, but instead of reducing gait compensations, hip abduction significantly increased during assistance in stroke subjects by 2.5°, whereas no change was observed in nondisabled control subjects. No change in pelvic obliquity was observed in either group. Conclusions Hip abduction increased when stroke subjects received assistive knee flexion torque at foot-off. These findings are in direct contrast to the traditional belief that pelvic obliquity combined with hip abduction is a compensatory mechanism to facilitate foot clearance during swing. Because no evidence suggested a voluntary mechanism for this behavior, we argue that these results were most likely a reflection of an altered motor template occurring after stroke. PMID:20576947

    1991-09-01

    This document contains the text of a 1991 Chinese amended law which seeks to punish criminals who abduct and sell women and children. The law assigns a prison sentence of 3-10 years and a fine for the abduction and sale of women and children. When circumstances are deemed especially serious, the penalty is increased to death and confiscation of property. Such circumstances include being the ringleader of a group which abducts and sells women and children, abducting and selling three or more women or children, raping abducted women, inducing or forcing women to prostitution, causing serious injury or death to abducted women and children or their relatives, and selling women and children outside of the territory. A 10-year sentence is to be imposed for the use of force, threats, or narcotics to kidnap women and children to sell them. Those who buy abducted women or children are also to be punished unless they fail to obstruct the women from returning to their home, fail to abuse the children, or fail to obstruct the children from saving themselves.

    This review addresses issues related to the use of structured psychiatric diagnostic interviews in children and adolescents. Structured diagnostic interviews improve the diagnostic process by better organizing the collection of clinical data and eliminating biases when applying diagnostic criteria. Available interviews generally fall into two categories. Highly structured (or respondent-based) measures use a set script and record subject's responses without interpretation. Thus, they are useful for epidemiologic surveys or other settings in which nonclinical interviewers are used. Semistructured (or interviewer-based) tools allow clinical interpretation of responses as well as the incorporation of other sources of information, thereby making them more relevant for clinicians. Structured diagnostic instruments are currently most often used in research settings, but potentially are useful for clinical settings as well. This review also addresses challenges in psychiatric diagnosis, a brief history of diagnostic standards, and the potential limitations/advantages of using structured diagnostic interviews.

    2012-01-01

    Objective: To evaluate the outcome of modified Quad procedure in preteen and teen patients with brachial plexus birth palsy. Background: We have previously demonstrated a significant improvement in shoulder abduction, resulting from the modified Quad procedure in children (mean age 2.5 years; range, 0.5–9 years) with obstetric brachial plexus injury. Methods: We describe in this report the outcome of 16 patients (6 girls and 10 boys; 7 preteen and 9 teen) who have undergone the modified Quad procedure for the correction of the shoulder function, specifically abduction. The patients underwent transfer of the latissimus dorsi and teres major muscles, release of contractures of subscapularis pectoralis major and minor, and axillary nerve decompression and neurolysis (the modified Quad procedure). Mean age of these patients at surgery was 13.5 years (range, 10.1–17.9 years). Results: The mean preoperative total Mallet score was 14.8 (range, 10–20), and active abduction was 84° (range, 20°–140°). At a mean follow-up of 1.5 years, the mean postoperative total Mallet score increased to 19.7 (range, 13–25, P < .0001), and the mean active abduction improved to 132° (range, 40°–180°, P < .0003). Conclusion: The modified Quad procedure greatly improves not only the active abduction but also other shoulder functions in preteen and teen patients, as this outcome is the combined result of decompression and neurolysis of the axillary nerve and the release of the contracted internal rotators of the shoulder.

    Two forms of genetic instability have been described in colorectal cancer: chromosomal instability, characterized by structural and numerical chromosomal abnormalities and associated to aneuploidy; and microsatellite instability, characterized by a deficiency in the mismatch repair system that leads to slippage in microsatellites and is associated to euploidy. Thirteen colorectal cancer sample DNAs were analyzed after colectomy. High-resolution genome-wide DNA copy number and Single Nucleotide Polimorphism genotyping analysis was performed by Affymetrix SNP 6.0 arrays that interrogates 906,600 single nucleotide polymorphisms and 945,826 copy number probes. We implemented this analysis as part of a routine procedure that includes the sampling of fresh tissue from the tumor mass without affecting the subsequent standard histopathological procedure. The novel molecular technology allows the determination of a genome-wide molecular karyotype using only 500 ng of high-quality tumor DNA; it distinguishes the two main types of genomic instability, discriminating between chromosomal instability positive and negative tumors. It also detects loss of heterozygosity (LOH) regions, called copy neutral-LOH. Tumor-associated copy neutral-LOH regions may play a pivotal role in oncogenesis when they determine duplications of either activating or loss of function gene mutation. We observed recurrent gains of chromosomes 2, 7, 8q, 9, 12, 13, 20 and losses of chromosomes 4, 5, 8p, 15, 17p, 18, 22, and Y, in agreement with previous cytogenetic studies. The use of such sampling procedure could stimulate the routine detection of point mutations in specific genes, thus avoiding subsequent sectioning of formalin-fixed and paraffin-embedded samples.

    Background: Measuring cardiac markers in blood has been the main strategy for the diagnosis of acute myocardial infarction for nearly 50 years. Creatine kinase-MB (CK-MB) has been demonstrated to be a highly specific marker. Objectives: The present study aimed to assess the role of CK-MB changes following percutaneous coronary intervention (PCI) to predict one year outcomes of this procedure. Patients and Methods: This cohort study was conducted on 138 patients diagnosed with coronary artery disease who underwent PCI. Sixty-nine patients who had a CK-MB elevation ? 3 times upper limit of normal (ULN) post procedurally were considered as group I and 69 patients without cardiac enzyme rise after PCI were considered as the control group (group II). The composite end point of major adverse cardiac events (MACE) during one year was assessed by telephone follow-up or presentation at clinical visiting, and compared between the two groups. The MACE was defined as the appearance of at least one of the following events: mortality, repeated revascularization procedures, myocardial infarction, or cerebrovascular events. Results: Although one year mortality in the group I was 4 (5.8%), about two times greater than the other group 2 (2.9%), the difference was not significantly discrepant (P = 0.57). Moreover, 8 (11.6%) of patients in group I experienced one year MACE, while this rate in the other group was 4 (5.8%), with insignificant difference (P = 0.22). In group I, one case experienced coronary artery bypass surgery, one, exhibited cerebrovascular disease and one reported ST segment elevation myocardial infarction (STEMI), while two patients in the other group were suspicious of having non-ST segment elevation myocardial infarction (NSTEMI) and candidates for repeated PCI. Multivariate analysis revealed that increased post-procedural CK-MB ? 3 times UNL could not predict long-term MACE in patients who underwent selective PCI. Area under the curve (AUC) for predicting one year MACE was 0.593 (95% CI: 0.397 - 0.788), indicating inappropriate accuracy for this biomarker (P = 0.290). Conclusions: It seems that CK-MB ? 3 times ULN within 24 hours after PCI cannot independently predict one year MACE in patients undergoing PCI. PMID:25478525

    ABduction and External Rotation (ABER) sequence in magnetic resonance (MR) arthrography of the shoulder is particularly important to better depict abnormal conditions of some glenohumeral joint structures and surrounding tissues by making imaging possible under a stress position relevant to pathologic conditions. Among the structures and tissues better depicted in this position are articular surface of the supraspinatus tendon, anteroinferior portion of the glenoid labrum, and anterior band of the inferior glenohumeral band. Despite these benefits of the ABER sequence, it is either not being used extensively as part of shoulder MR arthrograms or, when utilized, not properly assessed, mostly due to some practical difficulties in setting up the sequence and unfamiliarity with the alignment of structures displayed on MR images. In this technical note, we aimed to explain the ABER sequence planning in a step-by-step manner with emphasis on scout series set-up, and also present an outline of anatomic landmarks seen on ABER images.

    Ensuring the safety of infants born in a hospital is a top priority and, therefore, requires a solid infant security plan. Using an interdisciplinary approach and a systematic change process, nursing leadership in collaboration with clinical nurses and security personnel analyzed the infant security program at this community hospital to identify vulnerabilities. By establishing an interdisciplinary approach to infant security, participants were able to unravel a complicated concept, systematically analyze the gaps, and agree to a plan of action. This resulted in improved communication and clarification of roles between the nursing and security divisions. Supply costs decreased by 17.4% after the first year of implementation. Most importantly, this project enhanced and strengthened the existing infant abduction prevention measures, hard wired the importance of infant security, and minimized vulnerabilities. PMID:22293642

    Avascular necrosis (AVN) of the femoral head is a serious complication in the management of developmental dislocation of the hip. Increasing the abduction angle increases its stability but compromises the vascularity of the femoral head. From our database of 240 children treated for developmental dislocation of hip by the two senior authors between 1998 and 2008, we defined two groups of children who underwent closed or medial open reduction of the hip after a failed Pavlik treatment or if patients presented late. In group 1, the reduced hip was immobilized in around 90° flexion, 60° abduction, and 0-10° internal rotation. In group 2 the hip was immobilized in around 45° of hip abduction with flexion and internal rotation as before. The first and second authors independently analysed these two groups blinded to the hip abduction angle. Our hypothesis was that a reduction in the hip abduction angle would reduce the incidence of AVN in the second group without compromising the stability. All eligible children were included, and there were 42 children in group 1 and 44 children in group 2. An almost equal number of children underwent closed and medial open reduction in both the groups. The age at reduction was a mode of 6 months (range 6-13 months) and 7 months (range 7-12 months), respectively. The abduction angle in the first group had a mode of 60° (range 52-70°) and the second group had a mode of 45° (range 38-50°). Radiographic evidence of AVN as described by Salter and colleagues was seen in eight children (19%) in the first group and seven children (16%) in the second group (P=0.78). Redislocation occurred in one child in the second group and none in the first group. In summary, the results show a nonsignificant reduction in the incidence of AVN when the hip abduction angle was reduced with no significant increased risk of redislocation. PMID:23407430

  8. The Abduction of Geographic Information Science: Transporting Spatial Reasoning to the Realm of Purpose and Design

    NASA Astrophysics Data System (ADS)

    Couclelis, Helen

    People intuitively understand that function and purpose are critical parts of what human-configured entities are about, but these notions have proved difficult to capture formally. Even though most geographical landscapes bear traces of human purposes, visibly expressed in the spatial configurations meant to serve these purposes, the capability of GIS to represent means-ends relationships and to support associated reasoning and queries is currently quite limited. This is because spatial thinking as examined and codified in geographic information science is overwhelmingly of the descriptive, analytic kind that underlies traditional science, where notions of means and ends play a negligible role. This paper argues for the need to expand the reach of formalized spatial thinking to also encompass the normative, synthetic kinds of reasoning characterizing planning, engineering and the design sciences in general. Key elements in a more comprehensive approach to spatial thinking would be the inclusion of abductive modes of inference along with the deductive and inductive ones, and the development of an expanded geographic ontology that integrates analysis and synthesis, form and function, landscape and purpose, description and design.

    Objective To evaluate hip abductor and adductor peak torque outputs and compare their ratios between sexes. Design A cross-sectional laboratory-controlled study. Setting Participants visited a laboratory and performed an isokinetic hip abductor and adductor test. All participants performed 2 sets of 5 repetitions of concentric hip abduction and adduction in a standing position at 60 degrees per second. Gravity was determined as a function of joint angle relative to the horizontal plane and was corrected by normalizing the weight of the limb on an individual basis. Participants A total of 36 collegiate athletes. Independent Variable Sex (20 females and 16 males). Main Outcome Measures Bilateral peak hip abductor and adductor torques were measured. The 3 highest peak torque values were averaged for each subject. Results Independent t tests were used to compare sex differences in hip abductor and adductor peak torques and the abductor:adductor peak torque ratios. Males demonstrated significantly greater hip abductor peak torque compared with females (males 1.29 ± 0.24 Nm/kg, females 1.13 ± 0.20 Nm/kg; P = 0.03). Neither hip adductor peak torque nor their ratios differed between sexes. Conclusions Sex differences in hip abductor strength were observed. The role of weaker hip abductors in females deserves further attention and may be a factor for higher risk of knee pathologies. PMID:24905541

    The diagnosis of a polyneuropathy (PNP) is particularly a clinically based diagnosis. The polyneuropathic syndrome consists of typical symptoms like paraesthesias, pain, cramps and fasciculations as well as characteristic signs like loss of tendon reflexes, weakness and wasting of muscles, sensory loss, cranial nerve palsy and alterations of the autonomic nervous system. The analysis of manifestation-types is very important for the differential diagnosis. The symmetrical sensory type of manifestation can be found in the beginning of almost all toxic neuropathies as well as in uremic and diabetic neuropathy. The symmetrical-motor type of manifestation can be a further development of the symmetrical sensory type of manifestation or exists from the beginning in the case for example of Guillain-Barré-Syndrome. The asymmetric type of manifestation can be observed in the vascular neuropathies and in some types of inflammatory neuropathies like the neuroborrelioses or the neuralgic amyotrophy. The investigation of the CSF, electromyography and electroneurography as well as a great number of chemical lab tests are important for the etiological classification. According to the etiology, the polyneuropathies can be subdivided into four groups such as inflammatory, vascular, exotoxic and endotoxic-metabolic-hereditary diseases. The most frequent etiologies are diabetes mellitus and chronic alcoholism. PMID:8191381

  16. Human rather than ape-like orbital morphology allows much greater lateral visual field expansion with eye abduction

    PubMed Central

    Denion, Eric; Hitier, Martin; Levieil, Eric; Mouriaux, Frédéric

    2015-01-01

    While convergent, the human orbit differs from that of non-human apes in that its lateral orbital margin is significantly more rearward. This rearward position does not obstruct the additional visual field gained through eye motion. This additional visual field is therefore considered to be wider in humans than in non-human apes. A mathematical model was designed to quantify this difference. The mathematical model is based on published computed tomography data in the human neuro-ocular plane (NOP) and on additional anatomical data from 100 human skulls and 120 non-human ape skulls (30 gibbons; 30 chimpanzees / bonobos; 30 orangutans; 30 gorillas). It is used to calculate temporal visual field eccentricity values in the NOP first in the primary position of gaze then for any eyeball rotation value in abduction up to 45° and any lateral orbital margin position between 85° and 115° relative to the sagittal plane. By varying the lateral orbital margin position, the human orbit can be made “non-human ape-like”. In the Pan-like orbit, the orbital margin position (98.7°) was closest to the human orbit (107.1°). This modest 8.4° difference resulted in a large 21.1° difference in maximum lateral visual field eccentricity with eyeball abduction (Pan-like: 115°; human: 136.1°). PMID:26190625

  17. Hypnosis as a diagnostic modality for vocal cord dysfunction.

    PubMed

    Anbar, R D; Hehir, D A

    2000-12-01

    Vocal cord dysfunction (VCD) is a condition of paradoxical adduction of the vocal cords during the inspiratory phase of the respiratory cycle. VCD often presents as stridorous breathing, which may be misdiagnosed as asthma. The mismanagement of this disorder may result in unnecessary treatment and iatrogenic morbidity. An association with psychogenic factors has been reported, and a higher incidence of anxiety-related illness has been demonstrated in patients with VCD. Definitive diagnosis of VCD is made by visualization of adducted cords during an acute episode using nasopharyngeal fiber-optic laryngoscopy. Diagnosis can be problematic, because it may be difficult to reproduce an attack in a controlled setting. To maximize diagnostic yield during laryngoscopy, provocation of symptoms using methacholine, histamine, or exercise challenges have been used. We report a case of an 11-year-old boy, wherein hypnotic suggestion was used as an alternative method to achieve a diagnosis of VCD. The patient was admitted to the pediatric intensive care unit for elective fiber-optic laryngoscopy to confirm a diagnosis of VCD. The patient had a 4-year history of refractory asthma, severe gastroesophageal reflux disease (GERD) for which he had undergone a Nissen fundoplication, and suspected VCD. At 9 years of age the patient began manifesting monthly respiratory distress episodes of a severe character different from those that had been attributed to his asthma. Typically, he awoke from sleep with shortness of breath and difficulty with inhalation. He described a "neck attack" during which he felt as if the walls of his throat were "beating together." The patient was at times noted by his mother to exhibit a "suckling" behavior before onset of his respiratory distress episodes. On 4 occasions the patient became unconscious during an attack and then spontaneously regained consciousness after a few minutes. On these occasions, he was transported by ambulance to the hospital and the severe difficulty with inhalation resolved within a few minutes on treatment with oxygen and bronchodilators. Sometimes he was noted to manifest wheezing for several hours, which was responsive to bronchodilator therapy. Given the severity of the patient's disease, it was imperative to determine whether VCD was a complicating factor. It was proposed that an attempt be made to induce VCD by hypnotic suggestion while the patient underwent a fiberscopic laryngoscopy to establish a definitive diagnosis. The patient and his mother gave written consent for this procedure. He was admitted for observation to the pediatric intensive care unit for the induction attempt. The patient requested that no local anesthesia be applied in his nose before passage of the laryngoscope because he wanted to eat right after the procedure. Therefore, the nasopharyngeal laryngoscope was inserted while he used self-hypnosis as the sole form of anesthesia. He demonstrated no discomfort during its passing. Once the vocal cords were visualized, the patient was instructed to develop an episode of respiratory distress while in a state of hypnosis by recalling a recent "neck attack." His vocal cords then were observed to adduct anteriorly with each inspiration. The patient then was asked to relax his neck. When he did, the vocal cords immediately abducted with inspiration, and he breathed easily. After removal of the laryngoscope, the patient alerted from hypnosis and said he felt well. He reported no recollection of the procedure, thus demonstrating spontaneous amnesia that sometimes is associated with hypnosis. Because the diagnosis of VCD was confirmed, the patient was encouraged to use self-hypnosis and speech therapy techniques to control his symptoms. He also was referred for counseling. To our knowledge this is the first description in the medical literature of the use of hypnotic suggestion for making a diagnosis of VCD. (ABSTRACT TRUNCATED) PMID:11099624

    A novel approach to diagnostics of a power generator is developed. It utilizes readily available data acquired by the existing computer-based monitoring/control system. Diagnostic procedures detect various trends in the generator data and interpret these trends in the generator data and interpret these trends as changes in the generator performance caused by incipient failures. Results of trend analyses, subjected to statistical validation, facilitate failure prediction and identification thus providing the justification for service when needed. The procedures are incorporated in a diagnostic system implemented in a PC interfaced with the existing VAX-based process monitoring and control system. The diagnostic system provides graphical display of the diagnostic messages.

    Pulmonary infiltrates in immunocompromised children often pose problems in terms of deciding on further diagnostic and therapeutic procedures, but few studies have evaluated the value of non-invasive and invasive diagnostic methods in paediatric populations. Both galactomannan ELISA and PCR protocols appear to be less useful in children than in adults. Invasive procedures, such as bronchoalveolar lavage or lung biopsy, can yield a pathohistological diagnosis and/or the isolation of a pathogen. Prospective studies in paediatric patients are needed urgently to assess the value of different diagnostic procedures and to define an effective and safe diagnostic strategy for the individual child.

    Background Contact pressure of UHMWPE acetabular cup has been shown to correlate with wear in total hip replacement (THR). The aim of the present study was to test the hypotheses that the cup geometry, abduction angle, thickness and clearance can modify the stresses in cemented polyethylene cups. Methods Acetabular cups with different geometries (Link®: IP and Lubinus eccentric) were tested cyclically in a simulator at 45° and 60° abduction angles. Finite element (FE) meshes were generated and two additional designs were reconstructed to test the effects of the cup clearance and thickness. Contact pressures at cup-head and cup-cement interfaces were calculated as a function of loading force at 45°, 60° and 80° abduction angles. Results At the cup-head interface, IP experienced lower contact pressures than the Lubinus eccentric at low loading forces. However, at higher loading forces, much higher contact pressures were produced on the surface of IP cup. An increase in the abduction angle increased contact pressure in the IP model, but this did not occur to any major extent with the Lubinus eccentric model. At the cup-cement interface, IP experienced lower contact pressures. Increased clearance between cup and head increased contact pressure both at cup-head and cup-cement interfaces, whereas a decreased thickness of polyethylene layer increased contact pressure only at the cup-cement interface. FE results were consistent with experimental tests and acetabular cup deformations. Conclusion FE analyses showed that geometrical design, thickness and abduction angle of the acetabular cup, as well as the clearance between the cup and head do change significantly the mechanical stresses experienced by a cemented UHMWPE acetabular cup. These factors should be taken into account in future development of THR prostheses. FE technique is a useful tool with which to address these issues. PMID:15904521

    The optical noninvasive diagnostic systems are now widely applied and investigated in different areas of medicine. One of the such techniques is the noninvasive spectrophotometry, the complex diagnostic technique consisting on elastic scattering spectroscopy, absorption spectroscopy, fluorescent diagnostics, photoplethismography, etc. Today a lot of real optical diagnostic systems indicate the technical parameters and physical data only as a result of the diagnostic procedure. But, it is clear that for the medical staff the more convenient medical information is needed. This presentation lights the general way for development a diagnostic system"s software, which can produce the full processing of the diagnostic data from a physical to a medical level. It is shown, that this process is a multilevel (3-level) procedure and the main diagnostic result for noninvasive spectrophotometry methods, the biochemical and morphological composition of the tested tissues, arises in it on a second level of calculations.

    Health management (HM) in any engineering systems requires adequate understanding about the system s functioning; a sufficient amount of monitored data; the capability to extract, analyze, and collate information; and the capability to combine understanding and information for HM-related estimation and decision-making. Rotorcraft systems are, in general, highly complex. Obtaining adequate understanding about functioning of such systems is quite difficult, because of the proprietary (restricted access) nature of their designs and dynamic models. Development of an EIM (exact inverse map) solution for rotorcraft requires a process that can overcome the abovementioned difficulties and maximally utilize monitored information for HM facilitation via employing advanced analytic techniques. The goal was to develop a versatile HM solution for rotorcraft for facilitation of the Condition Based Maintenance Plus (CBM+) capabilities. The effort was geared towards developing analytic and reasoning techniques, and proving the ability to embed the required capabilities on a rotorcraft platform, paving the way for implementing the solution on an aircraft-level system for consolidation and reporting. The solution for rotorcraft can he used offboard or embedded directly onto a rotorcraft system. The envisioned solution utilizes available monitored and archived data for real-time fault detection and identification, failure precursor identification, and offline fault detection and diagnostics, health condition forecasting, optimal guided troubleshooting, and maintenance decision support. A variant of the onboard version is a self-contained hardware and software (HW+SW) package that can be embedded on rotorcraft systems. The HM solution comprises components that gather/ingest data and information, perform information/feature extraction, analyze information in conjunction with the dependency/diagnostic model of the target system, facilitate optimal guided troubleshooting, and offer decision support for optimal maintenance.

    Diagnostics is an important concept in system health and monitoring of space operations. Many of the existing diagnostic algorithms utilize system knowledge in the form of diagnostic matrix (D-matrix, also popularly known as diagnostic dictionary, fault signature matrix or reachability matrix) gleaned from physical models. But, sometimes, this may not be coherent to obtain high diagnostic performance. In such a case, it is important to modify this D-matrix based on knowledge obtained from other sources such as time-series data stream (simulated or maintenance data) within the context of a framework that includes the diagnostic/inference algorithm. A systematic and sequential update procedure, diagnostic modeling evaluator (DME) is proposed to modify D-matrix and wrapper logic considering least expensive solution first. This iterative procedure includes conditions ranging from modifying 0s and 1s in the matrix, or adding/removing the rows (failure sources) columns (tests). We will experiment this framework on datasets from DX challenge 2009.

    Horizontal head rotation evokes significant responses from trochlear motoneurons of turtle that suggests they have a functional role in abduction of the eyes like that in frontal-eyed mammals. The finding is unexpected given that the turtle is generally considered lateral-eyed and assumed to have eye movements instead like that of lateral-eyed mammals, in which innervation of the superior oblique muscle by the trochlear nerve (nIV) produces intorsion, elevation, and adduction (not abduction). Using an isolated turtle head preparation with the brain removed, glass suction electrodes were used to stimulate nIV with trains of current pulses. Eyes were monitored via an infrared camera with the head placed in a gimble to quantify eye rotations and their directions. Stimulations of nIV evoked intorsion, elevation, and abduction. Dissection of the superior oblique muscle identified lines of action and a location of insertion on the eye, which supported kinematics evoked by nIV stimulation. Eye positions in alert behaving turtles with their head extended were compared with that when their heads were retracted in the carapace. When the head was retracted, there was a reduction in interpupillary distance and an increase in binocular overlap. Occlusion of peripheral fields by the carapace forces the turtle to a more frontal-eyed state, perhaps the reason for the action of abduction by the superior oblique muscle. These findings support why trochlear motoneurons in turtle respond in the same way as abducens motoneurons to horizontal rotations, an unusual characteristic of vestibulo-ocular physiology in comparison with other mammalian lateral-eyed species.

    Light has a unique potential for non-invasive tissue diagnosis. The relatively short wavelength of light allows imaging of tissue at the resolution of histopathology. While strong multiple scattering of light in tissue makes attainment of this resolution difficult for thick tissues, most pathology emanates from epithelial surfaces. Therefore, high-resolution diagnosis of many important diseases may be achieved by transmitting light to the surface of interest. The recent fiber-optic implementation of technologies that reject multiple scattering, such as confocal microscopy and optical low coherence interferometry, have brought us one step closer to realizing non-invasive imaging of architectural and cellular features of tissue. Optical coherence tomography (OCT) can produce high-resolution cross-sectional images of biological structures. Clinical OCT studies conducted in the gastrointestinal tract and cardiovascular system have shown that OCT is capable of providing images of the architectural (> 20 µm) microanatomy of a variety of epithelial tissues, including the layered structure of squamous epithelium and arterial vessels. Fine Needle Aspiration- Low Coherence Interferometry (FNA-LCI) is another optical diagnostics technique, which is a suitable solution to increase the effectiveness of the FNA procedures. LCI is capable of measuring depth resolved (axial, z) tissue structure, birefringence, flow (Doppler shift), and spectra at a resolution of several microns. Since LCI systems are fiber-optic based, LCI probes may easily fit within the bore of a fine gauge needle, allowing diagnostic information to be obtained directly from the FNA biopsy site. Fiber optic spectrally encoded confocal microscopy (SECM) is a new confocal microscopy method, which eliminates the need for rapid beam scanning within the optical probe. This advance enables confocal microscopy to be performed through small diameter probes and will allow assessment of internal human tissues in vivo at the cellular level. A detailed description of several fiber optics based systems for early diseases diagnosis, as well as preliminary clinic results, will be presented.

    Based on historical and current contributions, the operational diagnostic approach is examined from a psychopathological point of view. Operational diagnostic systems in psychiatry are characterised by an atomising approach. In this context, psychopathological symptoms are interpreted as elementary entities which can be combined into a specific diagnostic category. Many years before operational diagnostic systems were introduced into psychiatry, however, such an atomising procedure was criticised by authors like Karl Jaspers, Willy Mayer-Gross or Klaus Conrad. Furthermore, validation of diagnostic criteria of operational diagnostic systems has not succeeded so far using biological findings or results of family and follow-up studies. This may be one reason for the fact that categorical approaches in psychiatric diagnosis are questioned increasingly and dimensional diagnostic models are suggested. PMID:18259722

    Intelligent systems have been applied to today's problems and could also be applied to space operations integrity. One of these systems is the XMAN tool designed for 'troubleshooting' jet engines. XMAN is the eXpert MAiNtenance tool developed to be an expert information analysis tool which stores trending and diagnostic data on Air Force engines. XMAN operates with a 'network topology' which follows a flow chart containing engine management information reports required by the governments technical order procedures. With XMAN technology, the user is able to identify engine problems by presenting the assertions of the fault isolation logic and attempting to satisfy individual assertions by referring to the databases created by an engine monitoring system. The troubleshooting process requires interaction between the technician and the computer to acquire new evidence form auxiliary maintenance tests corroboration of analytical results to accurately diagnose equipment malfunctions. This same technology will be required for systems which are functioning in space either with an onboard crew, or with an unmanned system. The technology and lessons learned developing this technology while suggesting definite applications for its use with developing space systems are addressed.

  1. Lysosomal diseases: diagnostic update.

    Winchester, Bryan

    2014-07-01

    Technological developments in newborn and population screening, biomarker discovery for monitoring treatment and rapid high throughput DNA sequencing are having a great impact on the diagnostic procedure for symptomatic patients with lysosomal storage diseases. The use of dried blood spots, initially for newborn screening, has stimulated the introduction of automated, rapid and more sensitive methods for the assay of lysosomal enzymes, including the synthesis of novel substrates. Storage products and secondary metabolites in urine and cells can be identified and measured very accurately and sensitively by high performance liquid chromatography and tandem mass spectrometry. This has enhanced the preliminary metabolite screen for LSDs and facilitated the diagnosis of transport defects. Fast, reliable and affordable high throughput DNA sequencing, such as whole or selected exome sequencing, is helping to make diagnoses in difficult cases, to reveal novel gene defects, to widen the clinical spectrum of diseases and possibly to identify modifying genetic factors. Bioinformatics will be necessary to handle the data generated by these new technologies. Notwithstanding, these technical innovations, accurate and reliable diagnosis will still depend on the knowledge and experience of skilled laboratory staff. PMID:24711203

    An anterior labrum reconstruction and mini-capsular shift (ARMS) procedure was performed in 64 patients (69 shoulders) with traumatic anterior or anterior-inferior glenohumeral instability between 1984 and 1990. Sixty-three of the sixty-nine stabilizations were performed for recurrent dislocation and six were performed for recurrent subluxation. Eighty-eight percent of the patients (61 shoulders) were available for clinical follow-up at an average of 36 months (range 28-78). There were 44 males and 12 females with an average age of 28 years (range 15-46). Excellent range of motion was recorded at follow-up for the operated shoulder with an average of 180 degrees of forward elevation, 72 degrees of external rotation with the arm at the side, 92 degrees of external rotation with the arm in the 90 degree abducted position and 90 degrees of internal rotation with the arm in the 90 degree abducted position. The range of motion of the normal shoulder was 180 degrees, 76 degrees, 101 degrees and 94 degrees respectively. Utilizing the rating scale from the American Shoulder and Elbow Society, pain improved from 3.1 to 4.4, stability improved from 1.1 to 4.5, and function improved from 2.5 to 3.8 on the average. Subjective rating revealed 95% of the patients to be satisfied with the operative procedure. According to the criteria of Rowe et al, 90% of the results were good or excellent. Five patients (8%) suffered a recurrent dislocation at an average of 32 months after the surgery. Four resulted from significant trauma (6%). One patient (2%) complained of a single episode of subluxation during early recovery. Two patients required shoulder manipulations to improve motion. No other complications occurred. The patients reviewed in this study were actively involved in sports. The majority of pre- and postoperative Tegner ratings exceeded 7.0. PMID:7719779

    In recent years there has been methodological improvement in established nuclear medicine procedures, such as renal and skeletal scintigraphy and new very specific probes for treatment and diagnosis of urological diseases have been introduced into the clinical routine. New diagnostic methods, such as positron emission tomography (PET) using prostate-specific membrane antigen (PSMA) ligands for highly accurate tumor localization in recurrent prostate cancer have become available in many centers. The very high and selective accumulation of these PSMA ligands in tumor tissue has shown promising therapeutic results. Moreover, since 2013 a new radiopharmaceutical agent, radium-223 dichloride, has been approved for treatment of symptomatic bone metastases of prostate cancer. Better knowledge of indications, benefits and limitations of these procedures will help clinicians to adequately introduce them into patient management. This article summarizes the state of the art in established nuclear medicine procedures for urological disorders and also reports on new diagnostic and therapeutic possibilities. PMID:26162277

    End-to-end beam simulations for the driver linac have shown that the design meets the necessary performance requirements including having adequate transverse and longitudinal acceptances. However, to achieve reliable operational performance, the development of appropriate beam diagnostic systems and control room procedures are crucial. With limited R&D funding, beam simulations provide a cost effective tool to evaluate candidate beam diagnostic systems and to provide a critical basis for developing early commissioning and later operational activities. We propose to perform beam dynamic studies and engineering analyses to define the requisite diagnostic systems of the driver linac and through simulation to develop and test commissioning and operational procedures.

    Gynecologic applications of optical coherence tomography (OCT) are usually performed in combination with routine diagnostic procedures: laparoscopy and colposcopy. In combination with laparoscopy OCT is employed for inspection of fallopian tubes in cases of unrecognized infertility while in colposcopy it is used to identify cervix pathologies including cancer. In this paper we discuss methods for increasing diagnostic efficacy of OCT application in these procedures. For OCT-laparoscopy we demonstrate independent criteria for pathology recognition which allow to increase accuracy of diagnostics. For OCT-colposcopy we report on application of device for controlled compression allowing to sense the elasticity of the inspected cervix area and distinguish between neoplasia and inflammatory processes.

    Rural communities in the Haut-Uele Province of northern Democratic Republic of Congo live in constant danger of attack and/or abduction by units of the Lord's Resistance Army operating in the region. This pilot study sought to develop and evaluate a community-participative psychosocial intervention involving life skills and relaxation training and Mobile Cinema screenings with this war-affected population living under current threat. 159 war-affected children and young people (aged 7-18) from the villages of Kiliwa and Li-May in north-eastern DR Congo took part in this study. In total, 22% of participants had been abduction previously while 73% had a family member abducted. Symptoms of post-traumatic stress reactions, internalising problems, conduct problems and pro-social behaviour were assessed by blinded interviewers at pre- and post-intervention and at 3-month follow-up. Participants were randomised (with an accompanying caregiver) to 8 sessions of a group-based, community-participative, psychosocial intervention (n=79) carried out by supervised local, lay facilitators or a wait-list control group (n=80). Average seminar attendance rates were high: 88% for participants and 84% for caregivers. Drop-out was low: 97% of participants were assessed at post-intervention and 88% at 3 month follow-up. At post-test, participants reported significantly fewer symptoms of post-traumatic stress reactions compared to controls (Cohen's d=0.40). At 3 month follow up, large improvements in internalising symptoms and moderate improvements in pro-social scores were reported, with caregivers noting a moderate to large decline in conduct problems among the young people.

    Basketball players have to move laterally and quickly change their movement directions, especially during defensive moves. This study aimed to investigate how frontal and sagittal plane hip movements relate to fastness and quickness of lateral cutting maneuvers from sliding. Three-dimensional biomechanical data were obtained for 28 female college basketball players while they performed lateral cutting maneuvers using their left leg after 2 lateral sliding steps. The lateral cutting index (LCIndex) expressing fastness and quickness of lateral cutting maneuvers, peak hip abduction and extension velocities immediately before foot contact, hip abduction and extension velocities at foot contact, peak horizontal ground reaction force, frontal plane ground reaction force angle, and sacrum center of mass position were calculated. Simple and stepwise regression analyses were conducted to predict LCIndex. The former showed that greater maximum hip extension velocity (p = 0.03) and lesser hip abduction velocity (p = 0.04) as well as smaller ground reaction force angle (p = 0.001) and lower sacrum center of mass position (p = 0.001) at foot contact led to better LCIndex. The latter showed that sacrum center of mass position at foot contact and hip extension velocity explained 35.3% (p < 0.01) and 7.3% (p = 0.088) of variance in LCIndex, respectively. Our results did not suggest that hip abductor function is important for lateral sliding moves, instead suggesting that faster hip extension motions to kick the ground and lowering the body center of mass are crucial for better lateral deceleration-acceleration motions.

    Primary and acquired abdominal pathology accounts for a significant proportion of sepsis and SIRS in the ICU population. Abdominal processes often present a difficult diagnostic dilemma in the truly critically ill patient who, due to hemodynamic instability or severe acute respiratory distress syndrome (ARDS) requiring high-level ventilatory support, is at significant risk during transport to radiology department. Furthermore, the accuracy of radiologic studies in the ICU setting is often limited. Laparoscopy provides a "minimally invasive" definitive modality to diagnose intra-abdominal problems. It may quickly provide the necessary information to define further management. In selective circumstances, it may actually allow appropriate intervention. However, the overall mortality of patients who undergo diagnostic laparoscopy in the ICU is high regardless of diagnostic findingsduring this procedure. Although not a technically difficult procedure, diagnostic laparoscopy does require a certain skill level, especially when limited time and unfavorable patient physiology are taken into account. The use of diagnostic laparoscopy should be limited to patients in whom a therapeutic intervention is feasible. PMID:23761270

    In ITER diagnostics will operate in the very hard radiation environment of fusion reactor. Extensive technology studies are carried out during development of the ITER diagnostics and procedures of their calibration and remote handling. Results of these studies and practical application of the developed diagnostics on ITER will provide the direct input to DEMO diagnostic development. The list of DEMO measurement requirements and diagnostics will be determined during ITER experiments on the bases of ITER plasma physics results and success of particular diagnostic application in reactor-like ITER plasma. Majority of ITER diagnostic already passed the conceptual design phase and represent the state of the art in fusion plasma diagnostic development. The number of related to DEMO results of ITER diagnostic studies such as design and prototype manufacture of: neutron and ?–ray diagnostics, neutral particle analyzers, optical spectroscopy including first mirror protection and cleaning technics, reflectometry, refractometry, tritium retention measurements etc. are discussed.

    Summary A subjective sampling ratio between the case and the control groups is not always an efficient choice to maximize the power or to minimize the total required sample size in comparative diagnostic trials.We derive explicit expressions for an optimal sampling ratio based on a common variance structure shared by several existing summary statistics of the receiver operating characteristic curve. We propose a two-stage procedure to estimate adaptively the optimal ratio without pilot data. We investigate the properties of the proposed method through theoretical proofs, extensive simulation studies and a real example in cancer diagnostic studies. PMID:24948841

    This paper critically examines the experiences of formerly abducted young women during their captivity with the Lord Resistance Army rebels and in the resettlement and reintegration period. Special attention is given to their exercise of agency and choices. Using a qualitative design, narrative interviews were conducted with child mothers (N=21), local and civic actors (N=17), and the general community through focus groups (N=10). Data transcripts were analyzed using template analysis methods to derive meanings and increase understanding of the situation. Abducted children faced significant difficulties during their captivity and also during their resettlement and reintegration process, yet they continued to exhibit strong agency to cope with the new realities. Despite these difficulties, opportunities existed which were utilized by the young people, albeit to different degrees depending on each young person's ability and initiative (agency). Situational factors limiting the child mothers' agency were identified as embedded within the latter's environment. This study raises the importance of appreciation of the young women's agency in both the bush-captivity experience and resettlement and reintegration processes within the community, post-conflict.

    Objective To improve diagnostic assessment in Moebius syndrome by (1) creating more selective diagnostic subgroups and (2) conducting genetic evaluation in a large patient cohort. Design Prospective, observational study. Participants Attendees of 3 consecutive Moebius Syndrome conferences held in the United States, with a prior diagnosis of Moebius syndrome were invited to participate. Methods Participants underwent standardized ophthalmologic examination for Moebius syndrome minimum diagnostic criteria (MDC) (congenital, nonprogressive facial palsy and abduction deficit) and genetic testing for HOXA1, HOXB1, and TUBB3 mutations. Main Outcome Measures Number of patients meeting MDC and number with confirmed genetic mutation. Results A total of 112 participants from 107 families enrolled. Nineteen percent of participants (21/112) did not meet accepted MDC for Moebius syndrome because they had abduction deficits without facial palsy or facial palsy with full ocular motility. All five families with two affected individuals had at least one family member in this category, including two siblings with comitant strabismus who harbored a HOXB1 mutation. Four unrelated participants, also not meeting MDC, had large-angle exotropia, vertical gaze deficiency, and ptosis consistent with congenital fibrosis of the extraocular muscles type 3 (CFEOM3); 1 harbored a novel and 3 harbored previously reported de novo TUBB3 mutations. Three percent of participants (3/112) met MDC but also had restricted vertical gaze. The remaining 88 participants (79%) met MDC and had full vertical gaze. This group had relatively homogeneous findings and none had a family history of Moebius syndrome. Two previously undescribed phenomena were observed in this category: 1) volitional Bell’s phenomenon, and 2) intorsion with fixation. Conclusions While the genetic contributors to classic Moebius syndrome remain elusive, accuracy in clinical evaluation will properly subdivide patients to facilitate genetic testing as new candidate genes are identified. Failure to test ocular motility may lead to misdiagnosis of Moebius syndrome, especially in patients who have facial palsy with full ductions. Patients with exotropia, vertical gaze limitation, and ptosis do not have classic Moebius syndrome and may have TUBB3 mutations associated with CFEOM3. To optimize genetic analysis, we propose adding “full vertical motility” to the minimum diagnostic criteria for Moebius syndrome. PMID:24612975

    Olfactory dysfunction is a common disorder, especially in elderly people. From the etiological point of view a differentiation is made between sinunasal, traumatic and non-sinunasal causes of dysosmia. Olfactory disorders are often observed in neurodegenerative diseases, especially in patients with Parkinson's disease or Alzheimer's disease. Apart from an extensive medical history important diagnostic tools are a complete ear nose and throat (ENT) examination including nasal endoscopy and olfactory testing, for example, with "sniffin' sticks". For diagnostic purposes modern imaging procedures, such as magnetic resonance imaging (MRI) are becoming more and more important. For testing children, olfactory testing needs to be adapted and depending on the etiology, olfactory training, antiphlogistic and surgical procedures are the most promising therapeutic approaches. In cases of intracranial causes of dysosmia neurosurgeons should know and respect the anatomical structures of the olfactory signal pathway, not least for the long-term prognosis. PMID:24221226

    Gastroparesis is characterized by a constellation of upper gastrointestinal symptoms in association with delayed gastric emptying in the absence of mechanical outlet obstruction from the stomach. Major symptoms are nausea, vomiting, early satiety or postprandial fullness, bloating, and abdominal or epigastric pain. Idiopathic, diabetic, and postsurgical causes represent the most common etiologies. Diagnostic procedures for the evaluation of gastroparesis comprise gastric emptying scintigraphy (gold standard), (13)C-octanoate breath testing, and a wireless motility capsule. Management of gastroparesis includes normalization of nutritional state, relief of symptoms, glycemic control, and improvement of gastric emptying. Medical treatment entails use of prokinetic drugs, which are currently the first-line therapy. Nausea and vomiting might be positively influenced by antiemetic drugs. Gastric electronic stimulation and surgical interventions should be used in well-defined patients and represent a therapeutic option in tertiary centers. PMID:25940143

    This report summarizes an extensive effort made to understand how to effectively use the various diagnostic technologies to establish the condition of medium voltage underground cable circuits. These circuits make up an extensive portion of the electric delivery infrastructure in the United States. Much of this infrastructure is old and experiencing unacceptable failure rates. By deploying efficient diagnostic testing programs, electric utilities can replace or repair circuits that are about to fail, providing an optimal approach to improving electric system reliability. This is an intrinsically complex topic. Underground cable systems are not homogeneous. Cable circuits often contain multiple branches with different cable designs and a range of insulation materials. In addition, each insulation material ages differently as a function of time, temperature and operating environment. To complicate matters further, there are a wide variety of diagnostic technologies available for assessing the condition of cable circuits with a diversity of claims about the effectiveness of each approach. As a result, the benefits of deploying cable diagnostic testing programs have been difficult to establish, leading many utilities to avoid the their use altogether. This project was designed to help address these issues. The information provided is the result of a collaborative effort between Georgia Tech NEETRAC staff, Georgia Tech academic faculty, electric utility industry participants, as well as cable system diagnostic testing service providers and test equipment providers. Report topics include: •How cable systems age and fail, •The various technologies available for detecting potential failure sites, •The advantages and disadvantages of different diagnostic technologies, •Different approaches for utilities to employ cable system diagnostics. The primary deliverables of this project are this report, a Cable Diagnostic Handbook (a subset of this report) and an online knowledge based system (KBS) that helps utilities select the most effective diagnostic technologies for a given cable circuit and circuit conditions.

    PURPOSE. To evaluate results of the modified Boytchev procedure for recurrent anterior dislocation of the shoulder in 60 patients. METHODS. Medical records of 45 men and 15 women aged 20 to 44 years who underwent the modified Boytchev procedure for recurrent anterior dislocation of the right (n=44) and left (n=16) shoulders were reviewed. The mean number of dislocations was 14. Outcome was evaluated using the Burkhead and Rockwood criteria. RESULTS. The mean follow-up period was 56 months. Outcome was excellent in 32 patients, good in 21, and fair in 7. None had poor outcome. The mean external rotation deficit at 0º and 90º of abduction improved from 14º to 7º (p=0.04) and 18º to 7º (p=0.03), respectively. Two patients had fragmentation of the coracoid process, which was fixed with non-absorbable suture. Two patients had traction injury to the musculocutaneous nerve, which recovered after 6 months. One patient had recurrent dislocation that ruled out the chance of revision surgery. CONCLUSION. The modified Boytchev procedure is a viable and simple treatment for recurrent anterior shoulder dislocation. PMID:25163956

    Diagnostics are essential for predictable restorative dentistry. Both patient and clinician must agree on a treatment goal before the final restorations are delivered to avoid future disappointments. However, fully understanding the patient's desires is difficult. A useful tool to overcome this problem is the diagnostic wax-up and mock-up. A potential treatment outcome is modeled in wax prior to treatment and transferred into the patient's mouth using silicon indexes and autopolymerizing resin to obtain the patient's approval. Yet, this time-consuming procedure only produces a single version of the possible treatment outcome, which can be unsatisfactory for both the patient and the restorative team. Contemporary digital technologies may provide advantageous features to aid in this diagnostic treatment step. This article reviews opportunities digital technologies offer in the diagnostic phase, and presents clinical cases to illustrate the procedures. PMID:26171442

  7. [Cushing's syndrome: diagnostic exploration].

    PubMed

    Tabarin, A; Roger, P

    The diagnosis of Cushing's syndrome is one of the most perplexing and controversial problems in endocrinology. However, significant advances in the diagnosis procedures have been made in the past decade. The diagnostic studies involved in the evaluation of patients with suspected Cushing's syndrome fall into two categories: confirming the presence of true hypercortisolism and establishing the precise aetiology. Diagnosis of Cushing's syndrome: ambulatory screening relies on the overnight 1 mg dexamethasone test. Negative tests are confirmed by measuring cortisol in two 24-hour urine samples. If cortisol excretion is slightly above normal, a 48-hour low-dose dexamethasone suppression test or an intravenous infusion dexamethasone suppression test are required. Diagnosis of the aetiology of Cushing's syndrome: the first step is to establish if the hypercortisolism is ACTH-dependent or not. This step is solved by measuring plasma ACTH and cortisol in the late afternoon. Computed tomography scanning of the adrenal glands is required in ACTH-independent Cushing's syndrome. A unilateral tumour will be demonstrated in most of cases. If bilateral lesions are found, dynamic testing using cortisol releasing factor and/or metyrapone must be performed to confirm the ACTH-independency of the syndrome. In ACTH-dependent Cushing's syndrome, the major difficulty is to distinguish between a pituitary source and an ectopic source of ACTH secretion. Magnetic resonance imaging of the pituitary with gadolinium enhancement must be preferred to computed tomography scanning but its sensitivity is not better than 70-80% and false positives can occur. When no macroscopic pituitary lesion can be detected, bilateral inferior petrosal sinus sampling coupled to CRH injection for ACTH measurement will indicate the source of ACTH secretion. If this test indicates the patient has Cushing's disease, pituitary trans-sphenoidal surgery can be performed. If the test indicates the patient has ectopic ACTH-secretion, a cervico-thoraco-abdominal scanning is necessary to identify the tumour. In the case of occult tumour the hypercortisolism must be controlled by pharmacological agents and the imaging investigations must be repeated at appropriate intervals. PMID:8127815

    Interventional cardiology procedures result in substantial patient radiation doses due to prolonged fluoroscopy time and radiographic exposure. The procedures that are most frequently performed are coronary angiography, percutaneous coronary interventions, diagnostic electrophysiology studies and radiofrequency catheter ablation. Patient radiation dose in these procedures can be assessed either by measurements on a series of patients in real clinical practice or measurements using patient-equivalent phantoms. In this article we review the derived doses at non-pediatric patients from 72 relevant studies published during the last 22 years in international scientific literature. Published results indicate that patient radiation doses vary widely among the different interventional cardiology procedures but also among equivalent studies. Discrepancies of the derived results are patient-, procedure-, physician-, and fluoroscopic equipmentrelated. Nevertheless, interventional cardiology procedures can subject patients to considerable radiation doses. Efforts to minimize patient exposure should always be undertaken. PMID:20066141

  10. Interim analyses in diagnostic versus treatment studies: differences and similarities

    PubMed Central

    Gerke, Oke; Høilund-Carlsen, Poul Flemming; Poulsen, Mads Hvid; Vach, Werner

    2012-01-01

    The purpose of this paper was to contrast interim analyses in (randomized controlled) treatment studies with interim analyses in paired diagnostic studies of accuracy with respect to planning and conduct. The term ‘treatment study’ refers to a (randomized) clinical trial that aims to demonstrate the superiority or noninferiority of one treatment compared with another, and the term ‘diagnostic study’ to a clinical study that compares two diagnostic procedures, using a third diagnostic procedure as the gold standard. Though interim analyses in treatment studies and paired diagnostic studies show similarities in a priori planning of timing, decision rules, and the consequences of the analyses, they differ with respect to (1) the need for sample size adjustments, (2) the possibility of early decisions without early stopping, and (3) the impact of keeping results secret. These differences are due, respectively, to certain characteristics of paired diagnostic studies: the dependence of the sample size on the agreement rate between the modalities, multiple aims of diagnostic accuracy studies, and the advantages of early unblinding of results at the individual level. We exemplified our points by using a recent investigation at our institution on the detection of bone metastases from prostate cancer in patients with histologically confirmed prostate cancer in which 99mTc-MDP whole body bone scintigraphy was compared to positron emission tomography/computed tomography with 18F-fluorocholine as tracer, using magnetic resonance imaging as a reference.

    Temporomandibular disorders (TMD) or craniomandibular disorders, respectively, involve diseases of the teeth and periodontia as well as the masticatory muscles, temporomandibular joints and associated structures. It has been shown in recent years that psychological, social and general medical influences are of enormous importance in the etiology of TMD in addition to anatomical, physiological, parafunctional and other biological causes. This signifies that therapists confronted with TMD should already include at an early stage other specialists such as pain therapists, neurologists, ENT physicians, psychotherapists and physiotherapists. Patients need to be referred to dentists specializing in TMD when ENT examinations yield no pathological findings. The treatment of TMD is subdivided into the following steps that are always related to underlying diagnoses: informing patients, self-observation, relaxation therapy, behavioral therapy, physiotherapy, drug therapy, therapeutic local anesthesia, splint therapy, and, if necessary, prosthetic and/or orthodontic therapy to restore a stable occlusion.

    Acute dizziness is a frequent index symptom in the emergency department as well as in the rural practice office. Most acute dizziness, however, is not dangerous, but some types are highly dangerous. Clinical routine acute dizziness can be separated into frequent benign syndromes including benign paroxysmal positional vertigo (BPPV), vestibular neuritis, Meni?re's disease or vestibular migraine, and what is here referred to as the "white shark" of dizziness, i.e. a stroke in the posterior circulation or more rarely a tumor in the posterior fossa. A practical concept is presented to clarify most frequent acute dizziness syndromes using clinical and low budget methods. PMID:25883501

    2010-01-01

    Diagnostic bronchoscopy has undergone two major paradigm shifts in the last 40 years. First, the advent of flexible bronchoscopy gave chest physicians improved access to the tracheobronchial tree with a rapid learning curve and greater patient comfort compared with rigid bronchoscopy. The second paradigm shift has evolved over the last 5 years with the proliferation of new technologies that have significantly enhanced the diagnostic capabilities of flexible bronchoscopy compared with traditional methods. At the forefront of these new technologies is endobronchial ultrasound. In its various forms, endobronchial ultrasound has improved diagnostic yield for pulmonary masses, nodules, intrathoracic adenopathy, and disease extent, thereby reducing the need for more invasive surgical interventions. Various navigational bronchoscopy systems have become available to increase flexible bronchoscope access to small peripheral pulmonary lesions. Furthermore, various modalities of airway assessment, including optical microscopic imaging technologies, may play significant roles in the diagnosis of a variety of pulmonary diseases in the future. Finally, the combination of new diagnostic bronchoscopy technologies and novel approaches in molecular analysis and biomarker assessment hold promise for enhanced diagnosis and personalized management of many pulmonary disorders. In this review, we provide a contemporary review of diagnostic bronchoscopy developments over the past decade. PMID:20378726

    The ORION laser facility is one of the UK's premier laser facilities which became operational at AWE in 2010. Its primary mission is one of stockpile stewardship, ORION will extend the UK's experimental plasma physics capability to the high temperature, high density regime relevant to Atomic Weapons Establishment's (AWE) program. The ORION laser combines ten laser beams operating in the ns regime with two sub ps short pulse chirped pulse amplification beams. This gives the UK a unique combined long pulse/short pulse laser capability which is not only available to AWE personnel but also gives access to our international partners and visiting UK academia. The ORION laser facility is equipped with a comprehensive suite of some 45 diagnostics covering optical, particle, and x-ray diagnostics all able to image the laser target interaction point. This paper focuses on a small selection of these diagnostics.

    The frequencies and effective doses for the most common X-ray diagnostic examinations in Ukraine were assessed in the frame of the European Commission (EC) Study on European Population Doses from Medical Exposure (Dose Datamed 2). The average effective doses for all radiographic procedures were estimated using the ODS-60 software (Finland). The estimation of the effective doses for the chest film fluorography was carried out from the results of own representative measurements with thermoluminescent (TL) dosimetry and a standard Alderson-Rando phantom. The effective doses for fluoroscopy procedures were assessed using the Russian guidelines for estimation of effective doses. For all other X-ray examinations and procedures [computed tomography (CT), angiography and interventional procedures], typical effective dose values were taken from the EC Guidance RP154. The most frequently performed in Ukraine is chest film fluorography, with 389 examinations per 1000 population annually, reflecting in the greatest contribution to the total collective effective dose (CED) of 428 mSv per 1000 population (44 %). The total frequency and CED from all X-ray diagnostic examinations and procedures were estimated to be 1218 examinations and 1060 mSv per 1000 populations, respectively. The expected additional cancer risk from X-ray diagnostic examinations and interventional procedures is 2680 cases per year, with 1200 of them due to the contribution of chest fluorography. The main important action in radiation protection of patients in diagnostic radiology is the organisation of the monitoring of patient doses for different types of X-ray diagnostic examinations and replacement of chest film fluorography with digital X-ray systems.

    FACET, the Facility for Advanced Accelerator and Experimental Tests, is a new facility being constructed in sector 20 of the SLAC linac primarily to study beam driven plasma wakefield acceleration beginning in summer 2011. The nominal FACET parameters are 23GeV, 3nC electron bunches compressed to about 20 {micro}m long and focussed to about 10 {micro}m wide. Characterization of the beam-plasma interaction requires complete knowledge of the incoming beam parameters on a pulse-to-pulse basis. FACET diagnostics include Beam Position Monitors, Toroidal current monitors, X-ray and Cerenkov based energy spectrometers, optical transition radiation (OTR) profile monitors and coherent transition radiation (CTR) bunch length measurement systems. The compliment of beam diagnostics and their expected performance are reviewed. Beam diagnostic measurements not only provide valuable insights to the running and tuning of the accelerator but also are crucial for the PWFA experiments in particular. Beam diagnostic devices are being set up at FACET and will be ready for beam commissioning in summer 2011.

In order to implement the system, JAVA, VRML, HTML, and CORTONA are used as a basic language and a viewer. And also in order to add a kind of intelligence, Augmented Knowledge In Agent (AKIA) by using Back Propagation Neural Networks (BPNN) is used. And by this study, here can introduce the system that has the following basic mechanisms; By inputting physical data like temperature or blood pressure, the system would show a diagnostic assistance by TEXT. And also the bad place of body would be shown graphically if there were any. The system can be put onto Web, so that anybody could have this assistance at any place ubiquitously only if a person has Internetworking access.

    Saliva, a scientific and clinical entity familiar to every oral health researcher and dental practitioner, has emerged as a translational and clinical commodity that has reached national visibility at the National Institutes of Health and the President's Office of Science and Technology. "Detecting dozens of diseases in a sample of saliva" was issued by President Obama as one of the 14 Grand Challenges for biomedical research in the 21(st) Century (National Economic Council, 2010). In addition, NIH's 2011 Government Performance Report Act (GPRA) listed 10 initiatives in the high-risk long-term category (Collins, 2011). The mandate is to determine the efficacy of using salivary diagnostics to monitor health and diagnose at least one systemic disease by 2013. The stage is set for the scientific community to capture these national and global opportunities to advance and substantiate the scientific foundation of salivary diagnostics to meet these goals. A specific calling is to the oral, dental, and craniofacial health community. Three areas will be highlighted in this paper: the concept of high-impact diagnostics, the role of dentists in diagnostics, and, finally, an infrastructure currently being developed in the United Kingdom--The UK Biobank--which will have an impact on the translational and clinical utilizations of saliva.

    The induction accelerator was conceived by N. C. Christofilos and first realized as the Astron accelerator that operated at LLNL from the early 1960`s to the end of 1975. This accelerator generated electron beams at energies near 6 MeV with typical currents of 600 Amperes in 400 ns pulses. The Advanced Test Accelerator (ATA) built at Livermore`s Site 300 produced 10,000 Ampere beams with pulse widths of 70 ns at energies approaching 50 MeV. Several other electron and ion induction accelerators have been fabricated at LLNL and LBNL. This paper reviews the principal diagnostics developed through efforts by scientists at both laboratories for measuring the current, position, energy, and emittance of beams generated by these high current, short pulse accelerators. Many of these diagnostics are closely related to those developed for other accelerators. However, the very fast and intense current pulses often require special diagnostic techniques and considerations. The physics and design of the more unique diagnostics developed for electron induction accelerators are presented and discussed in detail.

    Young, K.M.

    1991-01-01

    The development and design of plasma diagnostics for the International Thermonuclear Experimental Reactor (ITER) present a formidable challenge for experimental plasma physicists. The large plasma size, the high central density and temperature and the very high thermal wall loadings provide new challenges for present measurement techniques and lead to a search for new methods. But the physics and control requirements for the long burn phase of the discharge, combined with very limited access to the plasma, constrained by the requirement for radiation shielding of the coils and sharing of access ports with heating and current drive power, remote manipulation, fueling and turn blanket modules, make for very difficult design choices. An initial attempt at these choices has been made by an international team of diagnostic physicists, gathering together in a series of three workshops during the ITER Conceptual Design Activity. This paper is based on that report and provides a summary of its most important points. To provide a background against which to place the diagnostic requirements and design concepts, the ITER device, its most important plasma properties and the proposed experimental program will be described. The specifications for the measurement of the plasma parameters and the proposed diagnostics for these measurements will then be addressed, followed by some examples of the design concepts that have been proposed. As a result of these design studies, it was clear that there were many uncertainties associated with these concepts, particularly because of the nuclear radiation environment, so that a Research and Development Program for diagnostic hardware was established. It will also be briefly summarized.

    Context: Prospective measures of high external knee-abduction moment (KAM) during landing identify female athletes at increased risk of patellofemoral pain (PFP). A clinically applicable screening protocol is needed. Objective: To identify biomechanical laboratory measures that would accurately quantify KAM loads during landing that predict increased risk of PFP in female athletes and clinical correlates to laboratory-based measures of increased KAM status for use in a clinical PFP injury-risk prediction algorithm. We hypothesized that we could identify clinical correlates that combine to accurately determine increased KAM associated with an increased risk of developing PFP. Design: Descriptive laboratory study. Setting: Biomechanical laboratory. Patients or Other Participants: Adolescent female basketball and soccer players (n = 698) from a single-county public school district. Main Outcome Measure(s): We conducted tests of anthropometrics, maturation, laxity, flexibility, strength, and landing biomechanics before each competitive season. Pearson correlation and linear and logistic regression modeling were used to examine high KAM (>15.4 Nm) compared with normal KAM as a surrogate for PFP injury risk. Results: The multivariable logistic regression model that used the variables peak knee-abduction angle, center-of-mass height, and hip rotational moment excursion predicted KAM associated with PFP risk (>15.4 NM of KAM) with 92% sensitivity and 74% specificity and a C statistic of 0.93. The multivariate linear regression model that included the same predictors accounted for 70% of the variance in KAM. We identified clinical correlates to laboratory measures that combined to predict high KAM with 92% sensitivity and 47% specificity. The clinical prediction algorithm, including knee-valgus motion (odds ratio [OR] = 1.46, 95% confidence interval [CI] = 1.31, 1.63), center-of-mass height (OR = 1.21, 95% CI = 1.15, 1.26), and hamstrings strength/body fat percentage (OR = 1.80, 95% CI = 1.02, 3.16) predicted high KAM with a C statistic of 0.80. Conclusions: Clinical correlates to laboratory-measured biomechanics associated with an increased risk of PFP yielded a highly sensitive model to predict increased KAM status. This screening algorithm consisting of a standard camcorder, physician scale for mass, and handheld dynamometer may be used to identify athletes at increased risk of PFP. PMID:24762234

    Primary tumours of the heart are extremely rare. Sarcomas are considered to be the most frequent histological type. This study presents two cases with a two-week and two-month history of fatigue, fever and shortness of breath. In both cases, cardiac tumours with pericardial effusion were diagnosed by means of echocardiography, being responsible for the above-mentioned symptoms. At the beginning of the diagnostic process, sarcomas seemed to be the likeliest cause of these symptoms. Establishment of the histopathological diagnosis based on the tumour biopsy turned out to be very difficult, and this delayed further therapeutic procedures. PMID:24399588

    The development of new diagnostic tools particularly for some parasitic "neglected diseases", is slowed or even hindered by limited resources assigned for basic and applied research in public institution and private sector. Even if the time-line and costs needed for developing a new In Vitro Diagnostic (IVD) test are generally lower compared to vaccines or new drugs, industry is poorly engaged in investing resources due to the perception of limited markets. To accelerate the development of diagnostics for the world's most deadly diseases, the World Health Organization's (WHO) Special Programme for Research and Training in Tropical Diseases (TDR), the United Nations Development Programme, the World Bank and the Gates Foundation, last year launched a new initiative, FIND (Foundation for Innovative New Diagnostics, www.finddiagnostics.org). The aim is to "apply the latest biotechnology innovations to develop and validate affordable diagnostic tests for diseases of the developing world". Ideally, a new diagnostic test should be accurately evaluated prior to use in medical practice. The first step would be a pre-clinical evaluation, an analytic study to determine its laboratory performance. A crucial point in this phase is the calibration of reagents (antigens, antibodies, DNA probes, etc.) against a standard reference preparation. WHO, through the WHO International Laboratories for Biological Standards, "provides International Biological Reference Preparations which serve as reference sources of defined biological activity expressed in an internationally agreed unit" (www.who.int/biologicals/IBRP/index.htm). Standardization allows "comparison of biological measurements worldwide" and ensures the reliability of diagnostic procedures. These preparations are generally intended for use in the characterization of the activity of secondary reference preparations (regional, national or in-house working standards). Unfortunately, international reference standards for parasitic diseases are not available at present, except for Toxoplasma antibodies. The first international standard reagent for Anti-Toxoplasma Serum was established in 1968 and at present, an international standard reference serum, Anti-toxoplasma serum, human TOXM is available at the National Institute for Biological Standards and Control (NIBSC) in UK. Several collaborative, multicenter studies were carried out to assess the performance of different methods and commercial tests for the diagnosis of toxoplasmosis, by providing to participating laboratories a panel of well-defined sera to be tested. A four-phase process following well-accepted methodological standards for the development of diagnostics, analogous to those internationally accepted for drugs and vaccines was recently proposed. The pre-clinical evaluation, the analytic study to assess sensitivity, specificity, predictive values in laboratory (phase I), should be followed by a proof of principle study to distinguish diseased from healthy persons in easily accessible populations (phase II). The evaluation of test performance in populations of intended use (phase III), and finally the delineation of cost-effectiveness and societal impact of new tests in comparison with existing tools (phase IV) should complete the validation procedure. In this context, national regulatory agencies play a major role in pre-market approval and post-market surveillance of IVDs. The European Community in 1998 approved a directive (Directive 98/79/EC) which rules the marketing of IVD medical devices, in order to harmonise the performance levels and standards in European countries. But, among IVDs for parasitic diseases, only those to detect congenital toxoplasmosis are submitted to defined procedures to provide the verification of products before their placing on the market and the surveillance after their marketing by a notified body, which perform appropriate examinations, tests and inspections to production facilities to verify if the device meets the requirements of the directive.

    Advanced diagnostic technologies, such as polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA), have been widely used in well-equipped laboratories. However, they are not affordable or accessible in resource-limited settings due to the lack of basic infrastructure and/or trained operators. Paper-based diagnostic technologies are affordable, user-friendly, rapid, robust, and scalable for manufacturing, thus holding great potential to deliver point-of-care (POC) diagnostics to resource-limited settings. In this review, we present the working principles and reaction mechanism of paper-based diagnostics, including dipstick assays, lateral flow assays (LFAs), and microfluidic paper-based analytical devices (?PADs), as well as the selection of substrates and fabrication methods. Further, we report the advances in improving detection sensitivity, quantification readout, procedure simplification and multi-functionalization of paper-based diagnostics, and discuss the disadvantages of paper-based diagnostics. We envision that miniaturized and integrated paper-based diagnostic devices with the sample-in-answer-out capability will meet the diverse requirements for diagnosis and treatment monitoring at the POC.

    The term 'microsporidia' is a nontaxonomic designation which is used to refer to a group of intracellular parasites belonging to the phylum Microspora. These eukaryotic obligate intracellular protozoans have been described infecting every major animal group, especially insects, fish and mammals. They are important agricultural parasites in commercially important insects, fish, laboratory rodents, rabbits, fur-bearing animals, and primates. There is now an increasing recognition of microsporidia as important opportunistic pathogens in persons infected with the human immunodeficiency virus (HIV). Microsporidia possess ribosomes with features resembling prokaryotes. Phylogenetic analysis of the rRNA sequence from several of the microsporidia suggests that these organisms were early branches in the eukaryotic evolutionary line. The data on these molecular phylogenetic relationships are reviewed in this paper. Inroads have recently been made into the molecular biology of these organisms and these data are also presented. Diagnosis of microsporidia infection from stool examination is possible and has replaced biopsy as the initial diagnostic procedure in many laboratories. These staining techniques can be difficult, however, due to the small size of the spores. The specific identification of microsporidian species has classically depended on ultrastructural examination. With the cloning of the rRNA genes from the human pathogenic microsporidia it has been possible to apply polymerase chain reaction (PCR) techniques for the diagnosis of microsporidial infection at the species level. Both staining and PCR techniques for the diagnosis of microsporidia are reviewed. PMID:9554079

    In the last 10 to 15 years there has been much work done in trying to improve linear regression results. Individuals have analyzed the susceptibility of least-squares results to values far removed from the center of the independent variable observations. They have studied the problem of heavy-tailed residuals, and they have studied the problem of collinearity. From these studies have come ridge regression techniques, robust regression techniques, regression on principal components, etc. However, many practitioners view these methods with suspicion (and ignorance), and prefer to continue using the usual least-squares procedures to fit their models, even though their results might not be answering the question they think. In reaction to this, statisticians are spending more time analyzing how the individual observations affect the least squares results. In the last few years approximately 10 papers and one text have appeared that address the problem of how to study the influence of the individual observations. This report is a study of the recent work done in linear regression diagnostics. It is concerned with analyzing the effect of one case at a time, since the methods to analyze this situation are relatively straight-forward and are not prohibitive computationally.

    Microwaves (MWs) were first introduced as a method of fixation just over 20 years ago. In recent years their use has extended far beyond that of a safe, clean and rapid method of fixation of tissue blocks and large specimens, including brains. MWs accelerate the action of cross-linking fixatives and can greatly accelerate the various stages of tissue processing to produce a paraffin block in 30 min. An extensive range of ultrafast MW-stimulated special stains has been developed, and immunohistochemical procedures can be completed in 20 min by employing MWs. Cellular antigens are distinctly better preserved in tissues fixed by MWs than by conventional cross-linking fixatives. Also, the cytomorphology of cryostat sections irradiated in Wolman's solution is clearly improved. MWs can similarly be applied for fixation and staining of preparations for transmission and scanning electron microscopy, and they also greatly accelerate polymerisation of resins. In the current climate of cost containment, this wide range of applications makes the MW oven an invaluable addition to the diagnostic laboratory. PMID:8287207

    The real-time, personalized and highly sensitive early-stage diagnosis of disease remains an important challenge in modern medicine. With the ability to interact with matter at the nanoscale, the development of nanotechnology architectures and materials could potentially extend subcellular and molecular detection beyond the limits of conventional diagnostic modalities. At the very least, nanotechnology should be able to dramatically accelerate biomarker discovery, as well as facilitate disease monitoring, especially of maladies presenting a high degree of molecular and compositional heterogeneity. This article gives an overview of several of the most promising nanodevices and nanomaterials along with their applications in clinical practice. Significant work to adapt nanoscale materials and devices to clinical applications involving large interdisciplinary collaborations is already underway with the potential for nanotechnology to become an important enabling diagnostic technology.

    The ERL Prototype project is currently under development at the Brookhaven National Laboratory. The ERL is expected to demonstrate energy recovery of high-intensity beams with a current of up to a few hundred milliamps, while preserving the emittance of bunches with a charge of a few nanocoulombs produced by a high-current SRF gun. To successfully accomplish this task the machine will include beam diagnostics that will be used for accurate characterization of the three dimensional beam phase space at the injection and recirculation energies, transverse and longitudinal beam matching, orbit alignment, beam current measurement, and machine protection. This paper outlines requirements on the ERL diagnostics and describes its setup and modes of operation.

    The Phaedrus diagnostic system makes optimum use of probes and miniature gridded energy analyzers to measure detailed parameters such as density, plasma potential, and electron and ion energy. This requires miniaturization and provision for flexible access. Other diagnostics are made as flexible as possible. A multiple-aperture, end-loss analyzer is rotatable, allowing complete mapping of the end wall loss contours. Self-emissive probes are used to measure plasma potential contours in the end plugs. A single-channel neutral energy analyzer is movable and can be swept in energy. Secondary emission detector arrays supplement the neutral energy analyzer and give a measure of the ion energy versus pitch angle. Calibrated diamagnetic loops are used to measure the total plasma energy and its axial extent in each cell. Both permanent and insertable fast ion gauges are available. Completing the diagnostic system is a computerized data-acquisition system that is flexible and receptive to the time varying demands of the many ongoing experiments.

    Livingstone PathFinder (LPF) is a simulation-based computer program for verifying autonomous diagnostic software. LPF is designed especially to be applied to NASA s Livingstone computer program, which implements a qualitative-model-based algorithm that diagnoses faults in a complex automated system (e.g., an exploratory robot, spacecraft, or aircraft). LPF forms a software test bed containing a Livingstone diagnosis engine, embedded in a simulated operating environment consisting of a simulator of the system to be diagnosed by Livingstone and a driver program that issues commands and faults according to a nondeterministic scenario provided by the user. LPF runs the test bed through all executions allowed by the scenario, checking for various selectable error conditions after each step. All components of the test bed are instrumented, so that execution can be single-stepped both backward and forward. The architecture of LPF is modular and includes generic interfaces to facilitate substitution of alternative versions of its different parts. Altogether, LPF provides a flexible, extensible framework for simulation-based analysis of diagnostic software; these characteristics also render it amenable to application to diagnostic programs other than Livingstone.

    Saliva presents a minimally invasive alternative medium to blood for performing diagnostics1. Microsphere sensors for ions, small organic molecules, and proteins are currently being developed and optical microarrays containing thousands of these sensors will be used for simultaneous multi-analyte analysis. The fiber bundle platform in use is 1mm in diameter and contains approximately 50,000 individually addressable 3.1?m fibers, each with an etched well capable of housing a single 3.1?m microsphere sensor. Micron-sized bead-based chemistries are produced in house, followed by deposition onto a fiber-optic bundle platform, allowing for multiplexed analysis. The ultimate goal is to develop a universal diagnostic system using saliva as the diagnostic medium. This platform will permit multiplexed analysis of a sample by integrating microfluidics with the optical arrays loaded with sensors capable of detecting relevant biomarkers associated with a wide range of disease states. Disease states that are currently under investigation include end stage renal disease (ESRD) and Sjoegrens Syndrome (SS).

    We describe our experience in the reduction of dislocation of the hip secondary to developmental dysplasia using ultrasound-guided gradual reduction using flexion and abduction continuous traction (FACT-R). During a period of 13 years we treated 208 Suzuki type B or C complete dislocations of the hip in 202 children with a mean age of four months (0 to 11). The mean follow-up was 9.1 years (five to 16). The rate of reduction was 99.0%. There were no recurrent dislocations, and the rate of avascular necrosis of the femoral head was 1.0%. The rate of secondary surgery for residual acetabular dysplasia was 19.2%, and this was significantly higher in those children in whom the initial treatment was delayed or if other previous treatments had failed (p = 0.00045). The duration of FACT-R was significantly longer in severe dislocations (p = 0.001) or if previous treatments had failed (p = 0.018). This new method of treatment is effective and safe in these difficult cases and offers outcomes comparable to or better than those of standard methods. PMID:25737526

    Patients are exposed to significant radiation doses during diagnostic and interventional urologic procedures. This study aimed to measure patient entrance surface air kerma (ESAK) and to estimate the effective dose during intravenous urography (IVU), extracorporeal shock-wave lithotripsy (ESWL), and ascending urethogram (ASU) procedures. ESAK was measured in patients using calibrated thermo luminance dosimeters, GR200A). Effective doses (E) were calculated using the National Radiological Protection Board (NRPB) software. A total of 179 procedures were investigated. 27.9 % of the patients underwent IVU procedures, 27.9 % underwent ESWL procedures and 44.2 % underwent ASU procedures. The mean ESAK was 2.1, 4.18 and 4.9 mGy for IVU, ESWL, and ASU procedures, respectively. Differences in patient ESAK for the same procedure were observed. The mean ESAK values were comparable with those in previous studies. PMID:25899610

    A diagnostic, genome-independent microbial fingerprinting method using DNA oligonucleotide microarrays was used for high-resolution differentiation between closely related Bacillus strains, including two strains of Bacillus anthracis that are monomorphic (indistinguishable) via amplified fragment length polymorphism fingerprinting techniques. Replicated hybridizations on 391-probe nonamer arrays were used to construct a prototype fingerprint library for quantitative comparisons. Descriptive analysis of the fingerprints, including phylogenetic reconstruction, is consistent with previous taxonomic organization of the genus. Newly developed statistical analysis methods were used to quantitatively compare and objectively confirm apparent differences in microarray fingerprints with the statistical rigor required for microbial forensics and clinical diagnostics. These data suggest that a relatively simple fingerprinting microarray and statistical analysis method can differentiate between species in the Bacillus cereus complex, and between strains of B. anthracis. A synthetic DNA standard was used to understand underlying microarray and process-level variability, leading to specific recommendations for the development of a standard operating procedure and/or continued technology enhancements for microbial forensics and diagnostics.

  2. The implementation of diagnostic reference levels to Australian radiology practice.

    2010-10-01

    At the present time, there is no national surveillance of the increasing ionising radiation dose to the population from diagnostic imaging procedures. As the number of procedures undertaken is increasing, it is expected that the population dose will also increase. A substantial component of that contribution is from multi-detector computed tomography (MDCT) systems. The Australian Radiation Protection & Nuclear Safety Agency (ARPANSA) estimates that the growth in MDCT scans, based on Medicare Benefits Schedule data, is increasing at approximately 9% per annum, with over 2 million MDCT scans being performed in 2009. The caput effective dose (mSv) from this modality is expected to be approaching 1.2 mSv per annum. If current dose-detriment models are accurate, the risk of induction of carcinogenic detriment from current MDCT scanning patterns is a significant public health issue that requires a concerted and ongoing response. For the application of ionising radiation in medicine, the International Commission on Radiological Protection recommends the conservative philosophy of Justification and Optimisation via the measurement of 'Diagnostic Reference Levels' to limit the potential overexposure of patients and decrease the overall population burden. The Australian government has commissioned ARPANSA to survey, calculate and construct representative national diagnostic reference levels for diagnostic imaging modalities that use ionising radiation. This will be achieved in close consultation with the professional organisations who represent the professionals responsible for the use of ionising radiation in diagnostic imaging. PMID:20958945

    The Hybrid Reactor(HR) can be considered an attractive actinide-burner or a fusion assisted transmutation for destruction of transuranic(TRU) nuclear waste. The hybrid reactor has two important subsystems: the tokamak neutron source and the blanket which includes a fuel zone where the TRU are placed and a tritium breeding zone. The diagnostic system for a HR must be as simple and robust as possible to monitor and control the plasma scenario, guarantee the protection of the machine and monitor the transmutation.

    Sarcoidosis is a multiorgan system disease that often presents insidiously. The diagnosis is often made fortuitously upon routine chest radiography or that done for other reasons. Blacks are more commonly affected than whites and age of onset is typically adolescents to young adults. Lung involvement is common and symptoms may include cough, dyspnea and chest pain. Extrapulmonary symptoms may include the skin, joint and eye findings. Bilateral hilar adenopathy is the classic finding on chest radiograph. Anemia or other cell line deficiencies, elevated liver enzymes, hypercalciuria, and EKG abnormalities may also be present. Angiotensin converting enzyme levels may be elevated but are not diagnostic. Histopathological confirmation of noncaseating granulomas is essential for diagnosis. It is generally performed through a biopsy of the most peripheral site possible, although transbronchial biopsy is commonly required. Finally, other possible etiologies must be evaluated and differentiated with a particular emphasis on tuberculosis due to the multiple overlapping symptoms and findings. Newer techniques such as proteomics and transcriptional gene signatures may contribute to the understanding of the pathophysiology of sarcoidosis, and may even serve as diagnostic tools in the future.

    A new spectroscopic diagnostic to measure the poloidal velocity profile of TFTR plasmas is presented. This diagnostic will be used to complement the measurements of T_i, v_?, and ni from the existing charge exchange spectroscopy system (CHERS) allowing the determination of radial electric field profiles using the force balance equation. A novel inversion technique has been developed to calculate local poloidal rotation velocities from line-integrated measurements. This technique can recover radial spatial resolution that is lost due to the curvature of the field lines. Poloidal velocity profiles across the entire minor radius of the plasma are measured using both intrinsic emission and charge exchange emission (CX) from neutral beams. Two opposing vertical views are required to handle effects of the CX cross section which can cause apparent velocities greatly in excess of expected poloidal velocites. Three high-throughput 0.085 m f/1.8 spectrometers are used at relatively low dispersion to produce pairs of spectra for 30 radial chords yielding a radial resolution ~3.5 cm. Spectra of the 5291 Åline of carbon are recorded on three 2D CCD cameras.

    The Z Refurbishment (ZR) Project is a program to upgrade the Z machine at SNL with modern durable pulsed power technology, providing additional shot capacity and improved reliability as well as advanced capabilities for both pulsed x-ray production and high pressure generation. The development of enhanced diagnostic capabilities is an essential requirement for ZR to meet critical mission needs. This report presents a comprehensive plan for diagnostic instrument and infrastructure development for the first few years of ZR operation. The focus of the plan is on: (1) developing diagnostic instruments with high spatial and temporal resolution, capable of low noise operation and survival in the severe EMP, bremsstrahlung, and blast environments of ZR; and (2) providing diagnostic infrastructure improvements, including reduced diagnostic trigger signal jitter, more and flexible diagnostic line-of-sight access, and the capability for efficient exchange of diagnostics with other laboratories. This diagnostic plan is the first step in an extended process to provide enhanced diagnostic capabilities for ZR to meet the diverse programmatic needs of a broad range of defense, energy, and general science programs of an international user community into the next decade.

  14. What is the risk of diagnostic endoscopic retrograde cholangiopancreatography before cholecystectomy?

    PubMed

    Jones, Wesley B; Blackwell, Joseph; McKinley, Brian; Trocha, Steven

    2014-08-01

    Many surgeons prefer to perform endoscopic retrograde cholangiopancreatography (ERCP) before cholecystectomy, specifically in patients at significant risk of having biliary pathology. However, a preoperative diagnostic ERCP, without the use of an endoscopic ultrasound or magnetic retrograde cholangiopancreatoscopy, remains controversial. This is the result of the risk of either performing an unnecessary procedure and/or the development of post-ERCP pancreatitis (PEP). We performed a retrospective review of all surgeon-performed ERCPs at our institution between July 2011 and May 2013. This was done to examine patients who had pericholecystectomy ERCP. We had 550 ERCPs performed at our institution during this time period, 169 of which were pericholecystectomy procedures. We divided the 169 patients who had a diagnostic procedure (Diagnostic group) from those who had known biliary pathology before intervention (Therapeutic group). As a result, 34 patients (20.1%) were placed in the Diagnostic group and 135 patients (79.9%) in the Therapeutic group. Of the 34 Diagnostic patients, four (11.8%) developed PEP. Fifteen (44.1%) had unnecessary procedures, two of which had PEP (2.9%). Of the 135 ERCPs in the Therapeutic group, 18 patients (13.4%) developed PEP. Five of the 11 who had unnecessary procedures developed PEP. Based on the low incidence of complications, diagnostic ERCP has an acceptable rate of pancreatitis and/or unnecessary procedures when performed in highly selected patients and before cholecystectomy when compared with patients undergoing therapeutic ERCP. However, more aggressive use of diagnostic imaging before ERCP should be adopted given the number of unnecessary procedures performed. PMID:25105391

    Reaching ability of the paretic upper extremity in individuals with stroke decreases with increased shoulder abduction (SABD) loads. Transcranial direct current stimulation (tDCS) has been implemented to improve movement ability following stroke. However, results from previous studies vary, perhaps due to the influence of impairment level and the type of motor tasks that were used to study the effects of tDCS. This study specifically examines the impact of SABD loading on the effects of tDCS in 9 individuals with moderate to severe chronic stroke. In 3 different sessions, participants repeated a reaching assessment with various SABD loads (supported on a haptic table, 25%, and 50% of maximum voluntary SABD torque) in random order, pre and post one of the following 15-min tDCS protocols: anodal stimulation of lesioned M1, cathodal stimulation of non-lesioned M1, or anodal stimulation of non-lesioned M1. Sham stimulation was also conducted preceding one of the tDCS sessions. The averaged maximum reaching distance over valid trials was calculated for each condition. We observed significant interactions between SABD load, tDCS protocol and time (i.e., pre or post-tDCS). Post hoc test showed that anodal stimulation of the lesioned M1 caused a clear trend (p = 0.058) of increasing the reaching ability at a medium level of SABD loading (25%), but not for higher loads (50%). This suggests that anodal stimulation increases residual corticospinal tract activity, which successfully increases reaching ability at moderate loads; however, is insufficient to make significant changes at higher SABD loads. We also found that cathodal stimulation of the non-lesioned M1 significantly (p = 0.018) decreased the reaching distance at a high level of SABD loading (50%). This study demonstrated, for the first time, that the effect of tDCS on the reaching ability is dependent on SABD loads in individuals with moderate to severe stroke. PMID:26029081

  16. Diagnostic Hysteroscopy - A Retrospective Study of 1545 Cases

    STEFANESCU, Andreea; MARINESCU, Bogdan

    2012-01-01

    ABSTRACT Introduction: The development of hysteroscopy has provided a minimally invasive approach to common gynecologic problems, such as abnormal uterine bleeding. Diagnostic hysteroscopy is considered now "the gold standard" by the Association of Professors of Gynecology and Obstetrics (2002) in investigation of abnormal uterine bleeding (AUB) in order to rule out organic endouterine causes of AUB. Although the World Health Organization (WHO) recommends hysterosapingography (HSG) alone for management of infertile women many specialists use hysteroscopy as a first-line routine exam for infertility patients regardless of guidelines. Material and method: This paper is a retrospective study of 1545 diagnostic hysteroscopies performed in the "Prof. Dr. Panait Sirbu" Obstetrics and Gynecology Hospital between January 1, 2008 and June 30, 2011. The following parameters were studied: diagnostic hysteroscopy indications, type of anesthesia used, correlation between pre-and postoperative diagnoses. Outcomes: Of 1545 diagnostic hysteroscopies, 78% of cases were performed without anesthesia; of the total of 299 cases of primary infertility diagnostic hysteroscopy showed in 34% of cases tubal obstruction and endouterine pathology; of the total 396 cases of secondary infertility under investigation, diagnostic hysteroscopy showed in 40% of cases tubal obstruction and endouterine pathology; the highest accuracy of HSG was noted for uterine malformation and minimal accuracy was observed for intrauterine adhesions. Conclusions: Our experience supports the opinion that diagnostic hysteroscopy should be a first-line routine exam in infertility. Because of the high rate of false positive results for HSG in our study and considering the other studies in specialty literature, we always perform a diagnostic hysteroscopy before Assisted Human Reproduction procedures regardless of the HSG aspect.

    Background Identifying risk factors for knee pain and anterior cruciate ligament (ACL) injury can be an important step in the injury prevention cycle. Objective We evaluated two unique prospective cohorts with similar populations and methodologies to compare the incidence rates and risk factors associated with patellofemoral pain (PFP) and ACL injury. Methods The ‘PFP cohort’ consisted of 240 middle and high school female athletes. They were evaluated by a physician and underwent anthropometric assessment, strength testing and three-dimensional landing biomechanical analyses prior to their basketball season. 145 of these athletes met inclusion for surveillance of incident (new) PFP by certified athletic trainers during their competitive season. The ‘ACL cohort’ included 205 high school female volleyball, soccer and basketball athletes who underwent the same anthropometric, strength and biomechanical assessment prior to their competitive season and were subsequently followed up for incidence of ACL injury. A one-way analysis of variance was used to evaluate potential group (incident PFP vs ACL injured) differences in anthropometrics, strength and landing biomechanics. Knee abduction moment (KAM) cut-scores that provided the maximal sensitivity and specificity for prediction of PFP or ACL injury risk were also compared between the cohorts. Results KAM during landing above 15.4 Nm was associated with a 6.8% risk to develop PFP compared to a 2.9% risk if below the PFP risk threshold in our sample. Likewise, a KAM above 25.3 Nm was associated with a 6.8% risk for subsequent ACL injury compared to a 0.4% risk if below the established ACL risk threshold. The ACL-injured athletes initiated landing with a greater knee abduction angle and a reduced hamstrings-to-quadriceps strength ratio relative to the incident PFP group. Also, when comparing across cohorts, the athletes who suffered ACL injury also had lower hamstring/quadriceps ratio than the players in the PFP sample (p<0.05). Conclusions In adolescent girls aged 13.3 years, >15 Nm of knee abduction load during landing is associated with greater likelihood of developing PFP. Also, in girls aged 16.1 years who land with >25 Nm of knee abduction load during landing are at increased risk for both PFP and ACL injury. PMID:24687011

    In order to define a new gondola structural specification and to quantify the balloon termination environment, NASA developed a balloon gondola diagnostics package (GDP). This addition to the balloon flight train is comprised of a large array of electronic sensors employed to define the forces and accelerations imposed on a gondola during the termination event. These sensors include the following: a load cell, a three-axis accelerometer, two three-axis rate gyros, two magnetometers, and a two axis inclinometer. A transceiver couple allows the data to be telemetered across any in-line rotator to the gondola-mounted memory system. The GDP is commanded 'ON' just prior to parachute deployment in order to record the entire event.

    There are several new developments in diagnostics at the SRRC. These new developments include an orbit feedback system, tune monitor, filling pattern monitor, time-domain coupled-bunch oscillation monitor, and an improved synchrotron radiation monitor. A global orbit feedback system as well as a local orbit feedback system have been developed to eliminate excursions from the reference orbit that are caused by various perturbations. A digital receiver-based tune monitor provides a fast tune reading as a complementary tool to the commercial spectrum analyzer. Transient digitizers are used to acquire real-time filling patterns. Turn-by-turn and bunch-by-bunch beam signals acquired by the transient digitizer can extract information from coupled-bunch oscillations. Updated synchrotron radiation monitors provide a more convenient user interface.

    Rig Diagnostic Tools is a suite of applications designed to allow an operator to monitor the status and health of complex networked systems using a unique interface between Java applications and UNIX scripts. The suite consists of Java applications, C scripts, Vx- Works applications, UNIX utilities, C programs, and configuration files. The UNIX scripts retrieve data from the system and write them to a certain set of files. The Java side monitors these files and presents the data in user-friendly formats for operators to use in making troubleshooting decisions. This design allows for rapid prototyping and expansion of higher-level displays without affecting the basic data-gathering applications. The suite is designed to be extensible, with the ability to add new system components in building block fashion without affecting existing system applications. This allows for monitoring of complex systems for which unplanned shutdown time comes at a prohibitive cost.

    The aim of the present study was to improve spleen-preserving procedures in patients undergoing laparotomy following abdominal trauma. Of a total 288 patients who underwent laparotomy for abdominal trauma in the Fourth General Surgical Department of Hardarpa?a Teaching Hospital between 1989 and 1996, 94 patients with splenic injuries were retrospectively analyzed. The mean age of these 94 patients, 69% whom were male, was 28.9 +/- 3.5 years. Traffic accidents were found to be the major cause of splenic injuries (71.3%) and diagnostic peritoneal lavage was frequently used as a diagnostic tool (58.8%). Grades IV and V splenic injuries were seen in 71 patients (75.4%), all of whom required splenectomy. Omentoplasty with partial splenectomy or omentoplasty with splenorrhaphy successfully controlled hemorrhage from the spleen in 22 patients (23.4%). The complication rate was calculated at 18.06% in this study, but no deaths occurred as a direct result of splenic injury. In conclusion, omentoplasty, partial splenectomy, and splenorrhaphy are safe and successful methods of controlling bleeding from a damaged spleen of grade III in patients without multiple injuries.

    2015-01-01

    Endoscopic ultrasound (EUS) has emerged as an important diagnostic and therapeutic modality in the field of gastrointestinal endoscopy. EUS provides access to many organs and lesions which are in proximity to the gastrointestinal tract and thus giving an opportunity to target them for therapeutic and diagnostic purposes. This modality also provides a real time opportunity to target the required area while avoiding adjacent vascular and other structures. Therapeutic EUS has found role in management of pancreatic fluid collections, biliary and pancreatic duct drainage in cases of failed endoscopic retrograde cholangiopancreatography, drainage of gallbladder, celiac plexus neurolysis/blockage, drainage of mediastinal and intra-abdominal abscesses and collections and in targeted cancer chemotherapy and radiotherapy. Infact, therapeutic EUS has emerged as the therapy of choice for management of pancreatic pseudocysts and recent innovations like fully covered removable metallic stents have improved results in patients with organised necrosis. Similarly, EUS guided drainage of biliary tract and pancreatic duct helps drainage of these systems in patients with failed cannulation, inaccessible papilla as with duodenal/gastric obstruction or surgically altered anatomy. EUS guided gall bladder drainage is a useful emergent procedure in patients with acute cholecystitis who are not fit for surgery. EUS guided celiac plexus neurolysis and blockage is more effective and less morbid vis-à-vis the percutaneous technique. The field of interventional EUS is rapidly advancing and many more interventions are being continuously added. This review focuses on the current status of evidence vis-à-vis the established indications of therapeutic EUS.

  3. Diagnostic strategies in osteomyelitis

    Technetium-/sup 99/ pyrophosphate bone scanning often identifies patients with osteomyelitis before roentgenographic findings appear. However, recent studies have shown that /sup 99/Tc bone scanning often gives false-negative results, especially in neonates. The accuracy of computed tomographic scanning and indium-111 leukocyte scanning for diagnosis of early osteomyelitis has not been established. /sup 99/Tc bone scanning often gives false-positive results in patients with other conditions leading to bone injury and repair, such as trauma or recent surgery, further limiting the usefulness of this imaging procedure. Newer imaging techniques have not been adequately evaluated to establish their specificity. Because of their high cost and unproved accuracy, these new imaging procedures should not be routinely applied until their usefulness has been established. Bone biopsy remains the procedure of choice for establishing the diagnosis in patients suspected clinically to have osteomyelitis with negative findings on roentgenography and /sup 99/Tc bone scanning. Although Staphylococcus aureus is the leading cause of osteomyelitis, other pathogens cause 30 to 40 percent of cases. Aspiration or biopsy of the involved bone is usually required to choose appropriate antibiotic therapy. Bone biopsy is essential in chronic osteomyelitis, since cultures of sinus drainage are unreliable. Osteomyelitis in diabetics with foot infection and in association with decubitus ulcers presents special problems. Radionuclide scanning often give false-positive results in these patients. Proper diagnosis usually requires careful assessment of clinical and roentgenographic findings. 33 references.

    The procedure for diagnostics of laser induced plasma (LIP) by optical emission spectroscopy technique is described. LIP was generated by focusing Nd:YAG laser radiation (1.064 nm, 50 mJ, 15 ns pulse duration) on the surface of pellet containing among other elements lithium. Details of the experimental setup and experimental data processing are presented. High speed plasma photography was used to study plasma evolution and decay. From those images optimum time for plasma diagnostics is located. The electron number density, Ne, is determined by fitting profiles of Li I lines while electron temperature, Te, was determined from relative intensities of Li I lines using Boltzmann plot (BP) technique. All spectral line recordings were tested for the presence of self-absorption and then if optically thin, Abel inverted and used for plasma diagnostic purposes.

    The diagnosis of pancreatic disease in small animal veterinary patients is complicated by nonspecific clinical signs and the limitations of diagnostic testing. Pancreatic cytology is a potential diagnostic tool, but safety and diagnostic yield are not well characterized in large patient cohorts. We hypothesized that pancreatic fine-needle aspiration (FNA) in dogs would frequently generate diagnostic-quality samples and subsequent adverse medical events would be uncommon. Ninety-two client-owned dogs undergoing pancreatic FNA for clinical diagnostic evaluation were identified retrospectively by a computer search for pancreatic cytology submissions. Archived slides were reviewed by a single board-certified clinical pathologist using a predetermined descriptive scheme. Medical records were reviewed for adverse events 48 hr following FNA, for concurrent procedures and diagnosis in patients with adverse events and for histology results. Diagnostic yield was calculated as the % cases in which a cytologic diagnosis could be achieved; correlation with histology or other confirmatory testing was determined when possible. Diagnostic yield was 73.5%, and the major pathologic process identified cytologically correlated with confirmatory testing in 10 out of 11 cases. There were 7 adverse events, all in dogs with significant comorbidities or undergoing other invasive procedures. Pancreatic FNA in dogs has a good diagnostic yield and a low rate of clinical complications in a large case series of dogs. Correlation of cytology and histology results was high in a limited number of cases. PMID:25776547

    While the etiology of most childhood cancers is largely unknown, epidemiologic studies have consistently found an association between exposure to medical radiation during pregnancy and risk of childhood cancer in offspring. The relation between early life diagnostic radiation exposure and occurrence of pediatric cancer risks is less clear. This review summarizes current and historical estimated doses for common diagnostic radiologic procedures as well as the epidemiologic literature on the role of maternal prenatal, children’s postnatal and parental preconception diagnostic radiologic procedures on subsequent risk of childhood malignancies Risk estimates are presented according to factors such as the year of birth of the child, trimester and medical indication for the procedure, and the number of films taken. The paper also discusses limitations of the methods employed in epidemiologic studies to assess pediatric cancer risks, the effects on clinical practice of the results reported from the epidemiologic studies, and clinical and public health policy implications of the findings. Gaps in understanding and additional research needs are identified. Important research priorities include nationwide surveys to estimate fetal and childhood radiation doses from common diagnostic procedures, and epidemiologic studies to quantify pediatric and lifetime cancer risks from prenatal and early childhood exposures to diagnostic radiography, computed tomography, and fluoroscopically-guided procedures.

    Background Graphical displays of results allow researchers to summarise and communicate the key findings of their study. Diagnostic information should be presented in an easily interpretable way, which conveys both test characteristics (diagnostic accuracy) and the potential for use in clinical practice (predictive value). Methods We discuss the types of graphical display commonly encountered in primary diagnostic accuracy studies and systematic reviews of such studies, and systematically review the use of graphical displays in recent diagnostic primary studies and systematic reviews. Results We identified 57 primary studies and 49 systematic reviews. Fifty-six percent of primary studies and 53% of systematic reviews used graphical displays to present results. Dot-plot or box-and- whisker plots were the most commonly used graph in primary studies and were included in 22 (39%) studies. ROC plots were the most common type of plot included in systematic reviews and were included in 22 (45%) reviews. One primary study and five systematic reviews included a probability-modifying plot. Conclusion Graphical displays are currently underused in primary diagnostic accuracy studies and systematic reviews of such studies. Diagnostic accuracy studies need to include multiple types of graphic in order to provide both a detailed overview of the results (diagnostic accuracy) and to communicate information that can be used to inform clinical practice (predictive value). Work is required to improve graphical displays, to better communicate the utility of a test in clinical practice and the implications of test results for individual patients. PMID:18405357

    Fully automated classification algorithms have been successfully applied to diagnose a wide range of neurological and psychiatric diseases. They are sufficiently robust to handle data from different scanners for many applications and in specific cases outperform radiologists. This article provides an overview of current applications taking structural imaging in Alzheimer's Disease and schizophrenia as well as functional imaging to diagnose depression as examples. In this context, we also report studies aiming to predict the future course of the disease and the response to treatment for the individual. This has obvious clinical relevance but is also important for the design of treatment studies that may aim to include a cohort with a predicted fast disease progression to be more sensitive to detect treatment effects. In the second part, we present our own opinions on i) the role these classification methods can play in the clinical setting; ii) where their limitations are at the moment and iii) how those can be overcome. Specifically, we discuss strategies to deal with disease heterogeneity, diagnostic uncertainties, a probabilistic framework for classification and multi-class classification approaches.

    The Strengths and Difficulties Questionnaire (SDQ) was designed to screen for behavioral problems in youths based on cutoff points that favor the instrument's diagnostic sensitivity. The present study aimed to analyze the discriminative validity of the SDQ to identify behavioral difficulties and prosocial resources in school-age children compared with the diagnostic data collected by the corresponding sections of the Development and Well-being Assessment (DAWBA). In addition, new cutoff points that value specificity were defined for the SDQ scales, exploring its diagnostic potential. This study was conducted in Brazil and assessed a community convenience sample that consisted of 120 children aged 6–12 years who were not under psychological/psychiatric treatment. The mothers of the participants also completed a sociodemographic questionnaire. Descriptive statistics were used to clinically characterize the sample. A ROC curve was used to assess the discriminant validity of the SDQ, and new cutoff points were established to maximize the instrument's specificity. The new cutoff points enabled a significant increase in specificity without a significant loss of sensitivity, which favors approaches based on measures of screening and diagnosis yet does not damage the instrument's screening capacity. The following increases were observed: 100% for the depressive disorder scale (cutoff point = 7), 95.1% for the generalized anxiety disorder scale (cutoff point = 7), 46.6% for the conduct disorder scale (cutoff point = 6), 19.2% for the hyperactive disorder scale (cutoff point = 8), and 27.6% for the antisocial personality disorder scale (cutoff point = 6). A cutoff point of 8 was applied to the prosocial behavior scale, which exhibited a 62.1% increase in specificity. The use of more specific cutoff points generated more accurate results and favored SDQ's use, particularly in contexts of care that require more precise and faster procedures for identification of problems.

    Minimally invasive probe and optical biopsy system based on optical spectra recording and analysis seem to be a promising tool for early diagnostics of breast cancer. Light scattering and absorption spectra are generated continuously as far as the needle-like probe with one emitting and several collecting optical fibers penetrates through the tissues toward to the suspicious area. That allows analyzing not only the state of local site, but also the structure of tissues along the needle trace. The suggested method has the advantages of automated on-line diagnosing and minimal tissue destruction and in parallel with the conventional diagnostic procedures provides the ground for decision-making. 165 medical trials were completed in Nizhny Novgorod Regional Oncology Centre, Russia. Independent diagnoses were the results of fine biopsy and histology. Application of wavelet expansion and clasterization techniques for spectra analysis revealed several main spectral types for malignant and benign tumors. Automatic classification algorithm demonstrated specificity ˜90% and sensitivity ˜91%. Large amount of information, fuzziness in criteria and data noisiness make neural networks to be an attractive analytic tool. The model based on three-layer perceptron was tested over the sample of 29 `cancer' and 29 `non-cancer' cases and demonstrated total separation.

    Two studies are presented in which the design of a procedural aid and the impact of an additional decision aid for process control were assessed. In Study 1, a procedural aid was developed that avoids imposing unnecessary extraneous cognitive load on novices when controlling a complex technical system. This newly designed procedural aid positively affected germane load, attention, satisfaction, motivation, knowledge acquisition and diagnostic speed for novel faults. In Study 2, the effect of a decision aid for use before the procedural aid was investigated, which was developed based on an analysis of diagnostic errors committed in Study 1. Results showed that novices were able to diagnose both novel faults and practised faults, and were even faster at diagnosing novel faults. This research contributes to the question of how to optimally support novices in dealing with technical faults in process control. PMID:23017295

    1992-01-01

    The System Diagnostic Builder (SDB) is an automated software verification and validation tool using state-of-the-art Artificial Intelligence (AI) technologies. The SDB is used extensively by project BURKE at NASA-JSC as one component of a software re-engineering toolkit. The SDB is applicable to any government or commercial organization which performs verification and validation tasks. The SDB has an X-window interface, which allows the user to 'train' a set of rules for use in a rule-based evaluator. The interface has a window that allows the user to plot up to five data parameters (attributes) at a time. Using these plots and a mouse, the user can identify and classify a particular behavior of the subject software. Once the user has identified the general behavior patterns of the software, he can train a set of rules to represent his knowledge of that behavior. The training process builds rules and fuzzy sets to use in the evaluator. The fuzzy sets classify those data points not clearly identified as a particular classification. Once an initial set of rules is trained, each additional data set given to the SDB will be used by a machine learning mechanism to refine the rules and fuzzy sets. This is a passive process and, therefore, it does not require any additional operator time. The evaluation component of the SDB can be used to validate a single software system using some number of different data sets, such as a simulator. Moreover, it can be used to validate software systems which have been re-engineered from one language and design methodology to a totally new implementation.

  18. Fundamentals of diagnostic ultrasonography.

    PubMed

    Noce, J P

    1990-01-01

    Diagnostic ultrasonography uses acoustical waves in the frequency range of 1 to 20 MHz. These waves obey Snell's law of reflection and refraction, which are rules ordinary to wave behavior. In ultrasound, the analogy to momentum is acoustic impedance. The acoustic impedance, Z, is equal to the density, p, times velocity, v. The ultrasound transducer converts electrical energy into ultrasound energy and vice versa. The transducer usually consists of a piezoelectric crystal composed of such ceramic materials as barium titanate, lead titanate, zirconate, or lead metaniobate. Five basic ultrasonic scanning modes play the major roles in clinical applications. A-mode, or amplitude-mode, scanning measures the tissue discontinuity along the scan axis. B-mode scanning produces a two-dimensional image of the tissue under study by combining A-mode signals from various directions through mechanical transducer scanning. M-mode, or time motion scanning, is an extension of the A-mode approach in which a single stationary transducer is used. The depth of the echo is displayed on the vertical axis; the brightness of the oscilloscope display is modulated by the echo amplitude. Real-time scanning, or rapid B-scanning, techniques provide continuous data acquisition at a rate sufficient to give the impression of the instantaneous motion of moving structures. Doppler scanning relies on the presence of motion. The Doppler effect occurs when there is relative motion between the source of sound and the receiver of the sound, causing a change in the detected frequency of the sound source. PMID:2261584

    The diagnostic criteria for Asperger syndrome (AS) are still controversial. ICD-10 and DSM-IV are usually used as a formal diagnostic criteria for AS. However, many papers point out there are many problems in ICD-10/DSM-IV. It is indicated that the diagnosis of AS using ICD-10/DSM-IV criteria is virtually impossible due to the rule of onset and precedence. ICD-10/DSM-IV criteria don't include core symptoms of AS, such as odd speech and limited intelligent interests reported by Hans Asperger. Most of the cases which are diagnosed as AS clinically meet the diagnostic criteria for autism or atypical autism(PDD-NOS) in ICD-10/DSM-IV. ICD-10/DSM-IV criteria is too narrow to diagnose AS. This causes much confusion and disadvantage for families, clinicians and researchers. We need to establish the clinically useful and reliable diagnostic criteria for AS. PMID:17354560

    Free Electron Lasers (FEL) present a unique set of beam parameters to the diagnostics suite. The FEL requires characterization of the full six dimensional phase space of the electron beam at the wiggler and accurate alignment of the electron beam to the optical mode of the laser. In addition to the FEL requirements on the diagnostics suite, the Jefferson Lab FEL is operated as an Energy Recovered Linac (ERL) which imposes additional requirements on the diagnostics. The ERL aspect of the Jefferson Lab FEL requires that diagnostics operate over a unique dynamic range and operate with simultaneous transport of the accelerated and energy recovered beams. This talk will present how these challenges are addressed at the Jefferson Lab FEL.

  3. Saliva Preservative for Diagnostic Purposes

    NASA Technical Reports Server (NTRS)

    Pierson, Duane L.; Mehta, Satish K.

    2012-01-01

    Saliva is an important body fluid for diagnostic purposes. Glycoproteins, glucose, steroids, DNA, and other molecules of diagnostic value are found in saliva. It is easier to collect as compared to blood or urine. Unfortunately, saliva also contains large numbers of bacteria that can release enzymes, which can degrade proteins and nucleic acids. These degradative enzymes destroy or reduce saliva s diagnostic value. This innovation describes the formulation of a chemical preservative that prevents microbial growth and inactivates the degradative enzymes. This extends the time that saliva can be stored or transported without losing its diagnostic value. Multiple samples of saliva can be collected if needed without causing discomfort to the subject and it does not require any special facilities to handle after it is collected.

    The foundation for the usefulness of any diagnostic test should be that it is both reliable and accurate in its clinical diagnosis. In this article we present the second of a two-part series on validity and reliability, discussing the assessment of reliability among raters of diagnostic tests and between diagnostics tests themselves. To examine reproducibility (reliability) among raters of diagnostic tests we present the calculation of two statistical procedures: (1) the kappa coefficient statistic when presented with categorical data for the presence or absence of a clinical diagnosis and (2) the intraclass correlation coefficient (ICC) for continuously scaled data among raters. The accuracy among diagnostic tests (i.e. their interchangeability) can be evaluated by application of (1) a Bland-Altman plot procedure (with its 95% limits of agreement) and (2) the Passing-Bablok regression procedure (for the identification and evaluation of systematic and proportional differences). When deciding whether to select a diagnostic test one must evaluate its ability to provide more precise information than a gold standard test, and whether in clinical practice it would be more beneficial for patients to adopt it.

    2015-01-01

    Pleural disease is common with a rising case frequency. Many of these patients will be symptomatic and require diagnostic and/or therapeutic procedures. Patients with pleural disease present to a number of different medical specialties, and an equally broad range of clinicians are therefore required to have practical knowledge of these procedures. There is often underestimation of the morbidity and mortality associated with pleural interventions, even those regarded as being relatively straightforward, with potentially significant implications for processes relating to patient safety and informed consent. The advent of thoracic ultrasound (TUS) has had a major influence on patient safety and the number of physicians with the necessary skill set to perform pleural procedures. As the variety and complexity of pleural interventions increases, there is increasing recognition that early specialist input can reduce the risk of complications and number of procedures a patient requires. This review looks at the means by which complications of pleural procedures arise, along with how they can be managed or ideally prevented.

    The purpose of this study was to assess the diagnostic value of imaging-guided core needle biopsy for the diagnosis of musculoskeletal lesions. Between 2004 and 2007, 309 biopsies (ultrasound 151, computed tomography 89, and fluoroscopy 69) were included. There were 142 soft tissue and 167 bony lesions. Diagnostic yields and accuracies were assessed using the chi-square test or Fisher’s exact test with Bonferroni’s correction when necessary. Overall diagnostic yield was 90.6% for all 309 lesions (bone 91.6% vs. soft tissue 89.3%, p?=?0.5125). The diagnostic accuracy of the 185 core needle biopsies, which were confirmed by definitive surgical biopsies, was 84.3% (bone 88.9% vs. soft tissue 79.1%, p?=?0.0669). The yields of homogenous bone tumours (96.8%) were not significantly higher than those of bone tumours with a heterogenic architecture (86.4%, p?=?0.0794). The difference between accuracies for homogenous bone tumours (89.1%) and heterogenous bone tumours (85.0%) was not significant (p?=?0.6930). However, for soft tissue tumours, homogenous tumours had a significantly higher diagnostic yield than heterogenous tumours (97.5% vs. 81.4%, p?=?0.0036). Diagnostic accuracy for homogenous tumours was also significantly higher than that for heterogenous soft tissue tumours (94.4% vs. 60.6%, p?procedure if it is performed selectively in soft tissue tumours with homogenous architectures.

    The achievement of the combustion research under microgravity depends substantially on the availability of diagnostic systems. The non-intrusive diagnostic systems are potentially applicable for providing the accurate, realistic and detailed information on momentum, mass and energy transport, complex gas phase chemistry, and phase change in the combustion field under microgravity. The non-intrusive nature of optical instruments is essential to the measurement of combustion process under microgravity which is very nervous to any perturbation. However, the implementation of the non-intrusive combustion diagnostic systems under microgravity is accompanied by several constraints. Usually, a very limited space is only available for constructing a highly sophisticated system which is so sensitive that it is easily affected by the magnitude of the gravitational force, vibration and heterogeneous field of temperature and density of the environments. The system should be properly adjusted prior to the experiment. Generally, it is quite difficult to tune the instruments during measurements. The programmed sequence of operation should also be provided. Extensive effort has been toward the development of non-intrusive diagnostic systems available for the combustion experiments under microgravity. This paper aims to describe the current art and the future strategy on the non-intrusive diagnostic systems potentially applicable to the combustion experiments under microgravity in Japan.

    Pedobarography can quantify static and dynamic foot pressure. Despite an increase in the clinical use of pedobarography, the results and the clinical diagnosis do not always correlate, leading to confusion and misdiagnosis. The authors evaluated the potential of pedobarography to diagnose several diseases associated with abnormal pressure across the plantar surface. The study included 72 patients (96 cases) between January 2009 and August 2012 with symptoms of excessive plantar pressure. The average age was 50.9 years (range, 18-92). Patients had the lesion for an average of 17 months (range, 8-29). Pedobarographic measurements were used to evaluate the compatibility between the highest pressure on pedobarography and the clinical peak pressure with plantar ulcers or calluses. Maximal peak pressure was evaluated by static and dynamic measurements using numeric and graphic measurements in pedobarography. The diagnostic validity of pedobarography was analyzed by comparing clinical peak pressure and pedobarographic measurements. The diagnostic validity of pedobarography was 17.7% to 51% for static measurement and 13.5% to 49% for dynamic measurement. The diagnostic validity of pedobarography was low for intractable plantar keratosis and metatarsal head callus associated with metatarsophalangeal dislocation in rheumatoid arthritis. However, it was 57% to 100% for Charcot arthropathy with midfoot ulcers. When used to compare numeric pressure and graphic peak pressure for each part of the foot, pedobarography showed low diagnostic correlation. Based on the study results, the diagnostic validity of pedobarography is low. PMID:25437079

    The identification of an infectious or noninfectious uveitis syndrome is important to determine the range of therapeutic and prognostic implications of that disease entity. Diagnostic dilemmas arise with atypical history, atypical clinical presentations, inconclusive diagnostic workup, and persistent or worsened inflammation despite appropriate immunosuppression. More invasive intraocular testing is indicated in these situations particularly in infectious uveitis where a delay in treatment may result in worsening of the patient’s disease and a poor visual outcome. Laboratory analysis of vitreous fluid via diagnostic pars plana vitrectomy is an important technique in the diagnostic armamentarium, but the most important aspects of sample collection include rapid processing, close coordination with an ophthalmic pathology laboratory, and directed testing on this limited collected sample. Culture and staining has utility in bacterial, fungal, and nocardial infection. Polymerase chain reaction (PCR) analysis has shown promising results for bacterial endophthalmitis and infection with mycobacterium tuberculosis whereas PCR testing for viral retinitides and ocular toxoplasmosis has a more established role. Antibody testing is appropriate for toxoplasmosis and toxocariasis, and may be complementary to PCR for viral retinitis. Masquerade syndromes represent neoplastic conditions that clinically appear as infectious or inflammatory conditions and should be considered as part of the differential diagnosis. Diagnostic vitrectomy and chorioretinal biopsy are thus critical tools for the management of patients in whom an infectious etiology of uveitis is suspected. PMID:24613892

    Varicocele is defined as abnormally dilated scrotal veins. It is present in 15 % of normal males and in 40 % of males with infertility. This disorder is a challenge for the physicians involved in the diagnosis and treatment, as the pathophysiology of varicocele is not yet completely understood. For this reason, accurate diagnostic criteria and clear indications for treatment in asymptomatic adolescents or adults with clinical or subclinical varicocele are still not defined. Ultrasonography (US) is considered the best method for calculating the volume of the testicles, measuring vein diameter and monitoring the growth of the testis in adolescent patients. Color-Doppler US is the method of choice for detecting spermatic vein reflux and for classifying the grade of varicocele. Various classification systems have been published with recommendations on how to perform US imaging of the scrotum. Currently, color-Doppler US and spectral analysis are the most effective, non-invasive diagnostic procedures as they allow detection of subclinical varicocele associated with infertility. Various techniques are used in the treatment of varicocele including open surgery, laparoscopic procedures and interventional radiology. However, there is no consensus among physicians on which technique is the most effective in terms of outcome and complication rates. This review shows that color-Doppler US is currently the most widely employed diagnostic method for detection and classification of varicocele caused by venous reflux, as it is reliable and easily performed. The review also highlights the role of varicocelectomy in the management of adult male infertility. PMID:25177391

  4. Telecommunication--a new tool for quality assurance and control in diagnostic pathology.

    Telepathology is the diagnostic work of a pathologist at a distance. It includes specific application fields which require specific system solutions. These comprise: a. frozen section service; b. expert consultations; c. remote control measurements, and d. education and training. Applications but, in addition, all aspects of diagnosis, especially those involved in the daily work flow of a pathologist. The image quality, transfer rates, and screen resolution of telepathology systems are sufficient for an additional or primary judgment of histological slides and cytological smears. It is, therefore, possible to include this technique into intralaboratory quality control of all steps of diagnostic procedures and to use this technique for quality assurance and control. Diagnostic quality is not a well defined term, and depends, in addition to external circumstances, on the diagnosis itself. The diagnostic quality can be maintained or even improved by use of telepathology systems. They can serve for control of image quality, access to various information sources, simultaneous transfer of images and diagnosis, and continuous education of the involved pathologists. For example, in continuous education and training, as a first step the pathologist should have access to an image data bank storing images related to the specific case, for example images taken from the same organ and from patients of similar age. The final stage would be an intra-diagnostic learning from the specific case; i.e. the time difference between questionnaires for a difficult diagnosis and the final diagnosis will become a minimum. Automated storing of the specific and diagnosis-associated images of the case will permit an open diagnostic system which will itself adjust to the micro-environment of the department of pathology. Although this future scenario has not been implemented to our knowledge, there is little doubt the development in telepathology will promote the technical procedures in the environment of a diagnostic pathologist. Telepathology is, therefore, not a substitute of conventional diagnostic procedures but a real improvement in the world of pathology. PMID:11057040

    More, earlier and better diagnostic work is being done nowadays, leasing to detection of abnormalities and preliminary stages that used to remain undetected; a large reservoir of subclinical disorders is found to exist. More intensive and sensitive diagnostic methods as a rule lead to higher disease prevalence figures, with the consequences of a seeming increase of disease risk, unnecessary further examinations, treatment and follow-up of individuals and overestimation of the effects of treatment. This may even start a vicious circle. More attention should be given to using diagnostic methods in such a way that the earlier and more frequent detection of disease actually profits the patient. The proof of this should be found in scientific (population) studies of the magnitude and severity of the burden of disease, the determinants of progression, the severity of abnormalities and diseases and the favourable effect of (early) treatment.

    2013-01-01

    Background Despite numerous methodological flaws in previous study designs and the lack of validation in primary care populations, clinical tests for identifying acromioclavicular joint (ACJ) pain are widely utilised without concern for such issues. The aim of this study was to estimate the diagnostic accuracy of traditional ACJ tests and to compare their accuracy with other clinical examination features for identifying a predominant ACJ pain source in a primary care cohort. Methods Consecutive patients with shoulder pain were recruited prospectively from primary health care clinics. Following a standardised clinical examination and diagnostic injection into the subacromial bursa, all participants received a fluoroscopically guided diagnostic block of 1% lidocaine hydrochloride (XylocaineTM) into the ACJ. Diagnostic accuracy statistics including sensitivity, specificity, predictive values, positive and negative likelihood ratios (LR+ and LR-) were calculated for traditional ACJ tests (Active Compression/O’Brien’s test, cross-body adduction, localised ACJ tenderness and Hawkins-Kennedy test), and for individual and combinations of clinical examination variables that were associated with a positive anaesthetic response (PAR) (P?0.05) defined as 80% or more reduction in post-injection pain intensity during provocative clinical tests. Results Twenty two of 153 participants (14%) reported an 80% PAR. None of the traditional ACJ tests were associated with an 80% PAR (P<0.05) and combinations of traditional tests were not able to discriminate between a PAR and a negative anaesthetic response (AUC 0.507; 95% CI: 0.366, 0.647; P>0.05). Five clinical examination variables (repetitive mechanism of pain onset, no referred pain below the elbow, thickened or swollen ACJ, no symptom provocation during passive glenohumeral abduction and external rotation) were associated with an 80% PAR (P<0.05) and demonstrated an ability to accurately discriminate between an PAR and NAR (AUC 0.791; 95% CI 0.702, 0.880; P<0.001). Less than two positive clinical features resulted in 96% sensitivity (95% CI 0.78, 0.99) and a LR- 0.09 (95% CI 0.02, 0.41) and four positive clinical features resulted in 95% specificity (95% CI 0.90, 0.98) and a LR+ of 4.98 (95% CI 1.69, 13.84). Conclusions In this cohort of primary care patients with predominantly subacute or chronic ACJ pain of non-traumatic onset, traditional ACJ tests were of limited diagnostic value. Combinations of other history and physical examination findings were able to more accurately identify injection-confirmed ACJ pain in this cohort. PMID:23634871

    Double balloon enteroscopy (DBE) is an advanced type of endoscopic procedure which brings the advantage of reaching the whole small bowel using anterograde or the retrograde route. This procedure is both diagnostic and interventional for a variety of small intestinal diseases, such as vascular lesions, tumors, polyps and involvement of inflammatory bowel diseases. Main indication is the diagnosis and treatment of mid-gastrointestinal bleeding according to the recent published data all over the world. The complication rates seem to be higher than conventional procedures but growing experience is lowering them and improving the procedure to be safe and well tolerated. This review is about the technique, indications, diagnostic importance and complications of DBE according to the literature growing since 2001. PMID:25789095

    One of the basic principles, stated explicitly in Article 4 of the EC Council Directive 97/43 Euratom, is optimization. This means that all radiological examinations should be performed with a dose that is As Low As Reasonably Achievable (ALARA principle applied to the protection of the patient) in order to obtain the required diagnostic information. Therefore, dose needs to be determined with the relationship between image quality and dose always kept in mind. In this paper, radiation quantities and units to report patient doses in diagnostic radiology will be identified.

    1988-01-01

    Extendable Integrated Support Environment (EISE) is a real-time computer network consisting of commercially available hardware and software components to support systems level integration, modifications, and enhancement to weapons systems. The EISE approach offers substantial potential savings by eliminating unique support environments in favor of sharing common modules for the support of operational weapon systems. An expert system is being developed that will help support diagnosing faults in this network. This is a multi-level, multi-expert diagnostic system that uses experiential knowledge relating symptoms to faults and also reasons from structural and functional models of the underlying physical model when experiential reasoning is inadequate. The individual expert systems are orchestrated by a supervisory reasoning controller, a meta-level reasoner which plans the sequence of reasoning steps to solve the given specific problem. The overall system, termed the Diagnostic Executive, accesses systems level performance checks and error reports, and issues remote test procedures to formulate and confirm fault hypotheses.

    Establishing the correct diagnosis in newborns presenting with blisters and erosions is not always a straightforward process. Many different disease entities including acquired (i.e., infectious, immunobullous, traumatic) and inherited disorders have to be taken into consideration. Similarities in clinical appearance, colonization and/or superinfections of preexisting skin lesions, as well as the absence of late changes in the neonate often pose significant diagnostic challenges. In this paper we discuss by giving examples the process of making an accurate diagnosis of blistering skin diseases in the neonatal period on the basis of a diagnostic algorithm. In addition, we provide an overview of the rational use and the limitations of laboratory procedures such as microbial testing, routine light microscopy, immunofluorescence antigen mapping, transmission electron microscopy, and molecular genetic analysis.

    The pursuit of timely, cost-effective, accurate, and noninvasive diagnostic methodologies is an endeavor of urgency among clinicians and scientists alike. Detecting pathologies at their earliest stages can significantly affect patient discomfort, prognosis, therapeutic intervention, survival rates, and recurrence. Diagnosis and monitoring often require painful invasive procedures such as biopsies and repeated blood draws, adding undue stress to an already unpleasant experience. The discovery of saliva-based microbial, immunologic, and molecular biomarkers offers unique opportunities to bypass these measures by utilizing oral fluids to evaluate the condition of both healthy and diseased individuals. Here we discuss saliva and its significance as a source of indicators for local, systemic, and infectious disorders. We highlight contemporary innovations and explore recent discoveries that deem saliva a mediator of the body's physiological condition. Additionally, we examine the current state of salivary diagnostics and its associated technologies, future aspirations, and potential as the preferred route of disease detection, monitoring, and prognosis.

    'The effort of the past year''s activities, which covers the first year of the project, was directed at developing DNA-based diagnostic procedures for implementation in high through-put analytical instrumentation. The diagnostic procedures under evaluation are designed to identify specific genes in soil microorganisms that code for pollutant-degrading enzymes. Current DNA-based diagnostic procedures, such as the ligase chain reaction (LCR) and the polymerase chain reaction (PCR), rely on gel electrophoresis as a way to score a diagnostic test. The authors are attempting to implement time-of-flight (TOF) mass spectrometry as a replacement for gel separations because of its speed advantage and potential for sample automation. The authors anticipate that if TOF techniques can be implemented in the procedures, then a very large number of microorganisms and soil samples can be screened for the presence of specific pollutant-degrading genes. The use of DNA-based procedures for the detection of biodegrading organisms or genes that code for pollutant-degrading enzymes constitutes a critical technology for following biochemical transformation and substantiating the impact of bioremediation. DNA-based technology has been demonstrated to be a sensitive technique for tracking micro-organism activity at the molecular level. These procedures can be tuned to identify groups of organisms, specific organisms, and activity at the molecular level. They are developing a P-monitoring strategy that relies on the combined use of DNA diagnostics with mass spectrometry as the detection scheme. The intent of this work is a two-fold evaluation of (1) the feasibility of replacing the use of gel separations for identifying polymerase chain reaction (PCR) products with a rapid and automatable form of electrospray mass spectrometry and (2) the use of matrix-assisted-laser-desorption-ionization mass spectrometry (MALDI-MS) as a tool to score oligonucleotide ligation assays (OLA).'

  1. Polarized radiation diagnostics of stellar magnetic fields

    NASA Astrophysics Data System (ADS)

    Mathys, Gautier

    The main techniques used to diagnose magnetic fields in stars from polarimetric observations are presented. First, a summary of the physics of spectral line formation in the presence of a magnetic field is given. Departures from the simple case of linear Zeeman effect are briefly considered: partial Paschen-Back effect, contribution of hyperfine structure, and combined Stark and Zeeman effects. Important approximate solutions of the equation of transfer of polarized light in spectral lines are introduced. The procedure for disk-integration of emergent Stokes profiles, which is central to stellar magnetic field studies, is described, with special attention to the treatment of stellar rotation. This formalism is used to discuss the determination of the mean longitudinal magnetic field (through the photographic technique and through Balmer line photopolarimetry). This is done within the specific framework of Ap stars, which, with their unique large-scale organized magnetic fields, are an ideal laboratory for studies of stellar magnetism. Special attention is paid to those Ap stars whose magnetically split line components are resolved in high-dispersion Stokes I spectra, and to the determination of their mean magnetic field modulus. Various techniques of exploitation of the information contained in polarized spectral line profiles are reviewed: the moment technique (in particular, the determination of the crossover and of the mean quadratic field), Zeeman-Doppler imaging, and least-squares deconvolution. The prospects that these methods open for linear polarization studies are sketched. The way in which linear polarization diagnostics complement their Stokes I and V counterparts is emphasized by consideration of the results of broad band linear polarization measurements. Illustrations of the use of various diagnostics to derive properties of the magnetic fields of Ap stars are given. This is used to show the interest of deriving more physically realistic models of the geometric structure of these fields. How this can possibly be achieved is briefly discussed. An overview of the current status of polarimetric studies of magnetic fields in non-degenerate stars of other types is presented. The final section is devoted to magnetic fields of white dwarfs. Current knowledge of magnetic fields of isolated white dwarfs is briefly reviewed. Diagnostic techniques are discussed, with particular emphasis on the variety of physical processes to be considered for understanding of spectral line formation over the broad range of magnetic field strengths encountered in these stars.

    Although diagnostic x-ray procedures provide important medical benefits, cancer risks associated with their exposure are also possible, but not well characterized. The US Radiologic Technologists Study (1983–2006) is a nationwide, prospective cohort study with extensive questionnaire data on history of personal diagnostic imaging procedures collected prior to cancer diagnosis. We used Cox proportional hazard regressions to estimate thyroid cancer risks related to the number and type of selected procedures. We assessed potential modifying effects of age and calendar year of the first x-ray procedure in each category of procedures. Incident thyroid cancers (n = 251) were diagnosed among 75,494 technologists (1.3 million person-years; mean follow-up = 17 years). Overall, there was no clear evidence of thyroid cancer risk associated with diagnostic x-rays except for dental x-rays. We observed a 13% increase in thyroid cancer risk for every 10 reported dental radiographs (hazard ratio = 1.13, 95% confidence interval: 1.01, 1.26), which was driven by dental x-rays first received before 1970, but we found no evidence that the relationship between dental x-rays and thyroid cancer was associated with childhood or adolescent exposures as would have been anticipated. The lack of association of thyroid cancer with x-ray procedures that expose the thyroid to higher radiation doses than do dental x-rays underscores the need to conduct a detailed radiation exposure assessment to enable quantitative evaluation of risk.

    1993-11-01

    Instrumented and optically-accessible rocket chambers are being developed to be used for diagnostics of small rocket (less than 440 N thrust level) flowfields. These chambers are being tested to gather local fluid dynamic and thermodynamic flowfield data over a range of test conditions. This flowfield database is being used to better understand mixing and heat transfer phenomena in small rockets, influence the numerical modeling of small rocket flowfields, and characterize small rocket components. The diagnostic chamber designs include: a chamber design for gathering wall temperature profiles to be used as boundary conditions in a finite element heat flux model; a chamber design for gathering inner wall temperature and static pressure profiles; and optically-accessible chamber designs, to be used with a suite of laser-based diagnostics for gathering local species concentration, temperature, density, and velocity profiles. These chambers were run with gaseous hydrogen/gaseous oxygen (GH2/GO2) propellants, while subsequent versions will be run on liquid oxygen/hydrocarbon (LOX/HC) propellants. The purpose, design, and initial test results of these small rocket flowfield diagnostic chambers are summarized.

    2010-01-01

    The Energy Recovery Linac (ERL) prototype project is currently under development at the Brookhaven National Laboratory. The ERL is expected to demonstrate energy recovery of high intensity beams with a current of up to a few hundred milliamps, while preserving the emittance of bunches with a charge of a few nanocoulombs produced by a high current SRF gun. To successfully accomplish this task the machine will include beam diagnostics that will be used for accurate characterization of the three dimensional beam phase space at the injection and recirculation energies, transverse and longitudinal beam matching, orbit alignment, beam current measurement, and machine protection. This report outlines requirements on the ERL diagnostics and describes its setup and modes of operation. The BNL Prototype ERL is an R&D effort aimed at reducing risks and costs associated with the proposed RHIC II electron cooler and eRHIC collider. The ERL will serve as a test bed for developing and testing instrumentation and studying physics and technological issues relevant to very high current ERL's. The prototype ERL, mated to a high current SRF gun, is expected to demonstrate production and energy recovery of high intensity, low emittance beams with a current of up to a few hundred milliamps. To successfully accomplish this task the ERL will include beam diagnostics required to characterize and tune beam parameters, as well as for machine protection. A preliminary diagnostics plan was presented in earlier publications. In this report, we describe the diagnostics presently planned to provide the data needed to meet these goals.

    Minimally invasive procedures, which include laparoscopic surgery, use state-of-the-art technology to reduce the damage to human tissue when performing surgery. Minimally invasive procedures require small “ports” from which the surgeon inserts thin tubes called trocars. Carbon dioxide gas may be used to inflate the area, creating a space between the internal organs and the skin. Then a miniature camera (usually a laparoscope or endoscope) is placed through one of the trocars so the surgical team can view the procedure as a magnified image on video monitors in the operating room. Specialized equipment is inserted through the trocars based on the type of surgery. There are some advanced minimally invasive surgical procedures that can be performed almost exclusively through a single point of entry—meaning only one small incision, like the “uniport” video-assisted thoracoscopic surgery (VATS). Not only do these procedures usually provide equivalent outcomes to traditional “open” surgery (which sometimes require a large incision), but minimally invasive procedures (using small incisions) may offer significant benefits as well: (I) faster recovery; (II) the patient remains for less days hospitalized; (III) less scarring and (IV) less pain. In our current mini review we will present the minimally invasive procedures for thoracic surgery. PMID:25861610

The methodical features of molding diagnostic competences in the above contingents are the design and organization of an educational process by applying systems integration and competence-based approaches; increased active self-directed learning of audience; a procedure to organize its unsupervised extracurricular activities. Professional habits and skills in laboratory specialists should be molded on the basis of didactic principles and in compliance with the found methodical patterns. The eventual result (molded competences) and its compliance with the practical health care requirements is assessed using all control types (incoming, running, intermediate, and ultimate ones). This ensures the stability and predictability of molding diagnostic competences in parasitology specialists. PMID:25850323

  16. Development of an otolaryngological interferometric fiber optic diagnostic probe

    NASA Astrophysics Data System (ADS)

    Conerty, Michelle D.; Castracane, James; Saravia, Eduardo; Parnes, Steven M.; Cacace, Anthony T.

    1992-08-01

    Current medical instrumentation research at InterScience, Inc. is aimed at utilizing state of the art electro-optics in the development of a diagnostic fiber optic instrument capable of quantifying vibration patterns in real time. This work is in collaboration with the Division of Otolaryngology of the Albany Medical College. The innovative diagnostic probe system design involves the miniaturization of an electronic speckle pattern interferometry (ESPI) system through the use of fiber optic elements coupled with high speed image acquisition from a solid state matrix detector. Subsequent frame by frame processing produces a high quality three-dimensional spatial representation of the vibrational pattern. The diagnostic probe system is being developed for quantitative tympanic membrane and vocal cord vibration analysis. The significance of the introduction of this instrument to the medical community is the contribution it could make in the efficiency and effectiveness of the diagnosis of otolaryngological disorders. Specific applications include the evaluation of tympanosclerosis, stiffness related middle ear disorders, ossicular chain abnormalities, tympanic membrane replacement, vocal dysphonias, and early detection of laryngeal carcinomas, cysts, and phenomenological properties of mucosal wave dynamics. The current instrumentation research is focused on the production of a prototype system for clinical trials. This research is based in ESPI optical system development and miniaturization, system hardware and software development, and clinical design of the probe heads within anatomical limitations. Significant advantages of this diagnostic tool over currently used instrumentation and procedures are the real time capabilities of the instrument, the ability to quantify the vibrational pattern in time and space, and the possibility of establishing a database of patient history and disorder characteristics. Once fully developed and integrated into the clinical environment, this system will have a profound effect on the diagnostic capabilities of the otolaryngologist and other clinicians and researchers of communication sciences and disorders.

    2015-01-01

    Diagnostic errors are common and costly, but difficult to detect. “Trigger” tools have promise to facilitate detection, but have not been applied specifically for inpatient diagnostic error. We performed a scoping review to collate all individual “trigger” criteria that have been developed or validated that may indicate that an inpatient diagnostic error has occurred. We searched three databases and screened 8568 titles and abstracts to ultimately include 33 articles. We also developed a conceptual framework of diagnostic error outcomes using real clinical scenarios, and used it to categorize the extracted criteria. Of the multiple criteria we found related to inpatient diagnostic error and amenable to automated detection, the most common were death, transfer to a higher level of care, arrest or “code”, and prolonged length of hospital stay. Several others, such as abrupt stoppage of multiple medications or change in procedure, may also be useful. Validation for general adverse event detection was done in 15 studies, but only one performed validation for diagnostic error specifically. Automated detection was used in only two studies. These criteria may be useful for developing diagnostic error detection tools. PMID:26097801

    1992-12-01

    In allergic rhinoconjunctivitis not only the nasal mucosa but also the conjunctiva and, in severe cases, the cornea are affected by reactive phenomena. This pathological process is often encountered in clinical practice, its incidence ranging from 10% to 30% of the whole population, as reported by many authors. Up to now, the pathogenetic mechanisms of allergic reactivity are not completely understood. In our opinion this is due to insufficient standardization of the diagnostic procedures; even the clinical picture of such a pathological process seems to be insufficient, especially with regard to the analogies between the nasal and conjunctival pathologies. To a great extent this depends on the different clinical pictures both in otorhinolaryngology and ophthalmology. Our study has been carried out on 98 patients suffering from rhinoconjunctivitis, and presents an accurate documentation with regard to the existence of analogies in reactivity at the immunoallergic level, in both the nose and conjunctiva. These are evident when we refer not only to specific routine allergological tests but, mainly, to local examinations. The evaluation of the selected data enables us to formulate a single classification of allergic rhinoconjunctivitis, taking into account the common reactive phenomena. PMID:1470828

    Hull, W. P.

    The author discusses some possible solutions to ASEA (active electronically scanned array) diagnostics in the operational environment using built-in testing (BIT), which can play a key role in reducing life-cycle cost if accurately implemented. He notes that it is highly desirable to detect and correct in the operational environment all degradation that impairs mission performance. This degradation must be detected with low false alarm rate and the appropriate action initiated consistent with low life-cycle cost. Mutual coupling is considered as a BIT signal injection method and is shown to have potential. However, the limits of the diagnostic capability using this method clearly depend on its stability and on the level of multipath for a specific application. BIT using mutual coupling may need to be supplemented on the ground by an externally mounted passive antenna that interfaces with onboard avionics.

    We built a system to guide decisions regarding the amount of genomic sequencing required to develop diagnostic DNA signatures, which are short sequences that are sufficient to uniquely identify a viral species. We used our existing DNA diagnostic signature prediction pipeline, which selects regions of a target species genome that are conserved among strains of the target (for reliability, to prevent false negatives) and unique relative to other species (for specificity, to avoid false positives). We performed simulations, based on existing sequence data, to assess the number of genome sequences of a target species and of close phylogenetic relatives (''near neighbors'') that are required to predict diagnostic signature regions that are conserved among strains of the target species and unique relative to other bacterial and viral species. For DNA viruses such as variola (smallpox), three target genomes provide sufficient guidance for selecting species-wide signatures. Three near neighbor genomes are critical for species specificity. In contrast, most RNA viruses require four target genomes and no near neighbor genomes, since lack of conservation among strains is more limiting than uniqueness. SARS and Ebola Zaire are exceptional, as additional target genomes currently do not improve predictions, but near neighbor sequences are urgently needed. Our results also indicate that double stranded DNA viruses are more conserved among strains than are RNA viruses, since in most cases there was at least one conserved signature candidate for the DNA viruses and zero conserved signature candidates for the RNA viruses.

An example is given of the use of many diagnostics in characterizing SiO{sub 2} and Si etching by fluorocarbons. {copyright} {ital 1997 American Institute of Physics.}

  14. Microwave diagnostics of atmospheric plasmas

    NASA Astrophysics Data System (ADS)

    Scott, David

    Plasma treatment of biological tissues has tremendous potential due to the wide range of applications. Most plasmas have gas temperatures which greatly exceed room temperature. These are often utilized in electro-surgery for cutting and coagulating tissue. Another type of plasma, referred to as cold atmospheric plasma, or CAP, is characterized by heavy particle temperatures which are at or near room temperature. Due to this lack of thermal effect, CAP may provide less invasive medical procedures. Additionally, CAP have been demonstrated to be effective at targeting cancer cells while minimizing damage to the surrounding tissue. A recently fabricated Microwave Electron Density Device (MEDD) utilizes microwave scattering on small atmospheric plasmas to determine the electron plasma density. The MEDD can be utilized on plasmas which range from a fraction of a millimeter to several centimeters at atmospheric pressure when traditional methods cannot be applied. Microwave interferometry fails due to the small size of the plasma relative to the microwave wavelength which leads to diffraction and negligible phase change; electrostatic probes introduce very strong perturbation and are associated with difficulties of application in strongly-collisional atmospheric conditions; and laser Thomson scattering is not sensitive enough to measure plasma densities less than 1012 cm-3. The first part of this dissertation provides an overview of two types of small atmospheric plasma objects namely CAPs and plasmas utilized in the electro-surgery. It then goes on to describe the fabrication, testing and calibration of the MEDD facility. The second part of this dissertation is focused on the application of the MEDD and other diagnostic techniques to both plasma objects. A series of plasma images that illustrate the temporal evolution of a discharge created by an argon electrosurgical device operating in the coagulation mode and its behavior was analyzed. The discharge of the argon electrosurgical system was studied using an Intensified Charge-Coupled Device (ICCD) and the MEDD. The plasma density was measured and found to be in the range of (7.5-9.5) x 1015 cm-3 for applied powers of 15-60 Watts. The discharge can be classified as a glow discharge of alternating current with a contracted positive column. The discharge ignites every half-wave of the driving voltage when voltage increases above the breakdown threshold of about 300 Volts and is interrupted at the end of each half-wave when the voltage approaches zero. Additionally, it was shown that the plasma discharges on the target object during the positive half-wave of the voltage. The power distribution was also analyzed. It was found that 60-70% of the input power is delivered into the tissue and the remaining 30-40% is consumed by the plasma column between the electrosurgical probe and tissue. The application of the MEDD to a helium CAP revealed the temporal dynamics of the discharge. It was observed that streamer development associated with the measured plasma density peak is developing on the decaying part of the main inter-electrode discharge. The third part of the dissertation focuses on the simulation of a helium CAP. A one-dimensional model of a helium CAP was used to simulate twenty-one oxygen, helium, and nitrogen species. One hundred and forty reactions were successfully used. The predicted maximum and average densities of the species were tabulated. Graphs of the species densities were presented showing the change in densities with respect to the radius of the CAP. The plasma bullets can be seen via these graphs, with most species displaying maximum densities at a radius which is not the center of the CAP. This shows that the plasma bullets are a disk-like structure at the moment of time presented. Values of E/p were varied from 20 -- 30 volts/cm Torr. Based on experimental results of moments in time with which the maximum plasma density occurs, this data can be used to predict the actual E/p values for future experiments.

    Objective To determine the outcome of surgical excision of Morton’s neuroma after a local anesthetic diagnostic block into the neuroma has relieved symptoms. Design A cohort study. Setting A university affiliated hospital. Patients A sequential series of 37 patients who underwent 41 excisions with at least 2 years’ follow-up. Seven patients had undergone repeat excision of a neuroma, and 34 primary excisions were performed. Surgery was performed by a specialist in orthopedic surgery of the foot and ankle. Intervention Excision of the Morton’s neuroma after a positive diagnostic block. Main outcome measures Grade of symptoms at follow-up done by independent review on a 4-point scale. Results Of 41 procedures, 11 had an unfavourable outcome: 4 procedures were graded 3, and 7 procedures were graded 4. Eight (24%) of the 34 primary procedures were reported as failures, and 3 (43%) of the 7 revision procedures were reported as failures. Most patients reported poor results owing to persistent pain. Conclusions Diagnostic blocks do not improve the results of surgery for excision of Morton’s neuroma and are not recommended. Because failure rates are greater than 20%, surgery for Morton’s neuroma should only be offered after a full course of nonoperative management. PMID:9575995

    Object classification can be facilitated if simple diagnostic features can be used to determine class membership. Previous studies have found that simple shapes may be diagnostic for emotional content and automatically alter the allocation of visual attention. In the present study, we analyzed whether color is diagnostic of emotional content and tested whether emotionally diagnostic hues alter the allocation of visual attention. Reddish-yellow hues are more common in (i.e., diagnostic of) emotional images, particularly images with positive emotional content. An exogenous cueing paradigm was employed to test whether these diagnostic hues orient attention differently from other hues due to the emotional diagnosticity. In two experiments, we found that participants allocated attention differently to diagnostic hues than to non-diagnostic hues, in a pattern indicating a broadening of spatial attention when cued with diagnostic hues. Moreover, the attentional broadening effect was predicted by self-reported measures of affective style, linking the behavioral effect to emotional processes. These results confirm the existence and use of diagnostic features for the rapid detection of emotional content. PMID:24659831

    We discuss three different observational diagnostics related to disks around hot stars: absorption line determinations of rotational velocities of Be stars; polarization diagnostics of circumstellar disks; and X-ray line diagnostics of one specific magnetized hot star, $\\theta^1$ Ori C. Some common themes that emerge from these studies include (a) the benefits of having a specific physical model as a framework for interpreting diagnostic data; (b) the importance of combining several different types of observational diagnostics of the same objects; and (c) that while there is often the need to reinterpret traditional diagnostics in light of new theoretical advances, there are many new and powerful diagnostics that are, or will soon be, available for the study of disks around hot stars.

  1. Influence of diagnostic criteria on the interpretation of adrenal vein sampling.

    Guidelines promote the use of adrenal vein sampling (AVS) to document lateralized aldosterone hypersecretion in primary aldosteronism. However, there are large discrepancies between institutions in the criteria used to interpret its results. This study evaluates the consequences of these differences on the classification and management of patients. The results of all 537 AVS procedures performed between January 2001 and July 2010 in our institution were interpreted with 4 diagnostic criteria used in experienced institutions where AVS is performed without cosyntropin (Brisbane, Padua, Paris, and Turin) and with criteria proposed by a recent consensus statement. AVS procedures were classified as unsuccessful, lateralized, or not lateralized according to each set of criteria. Almost 5× more AVS procedures were classified as unsuccessful with the strictest criteria than with the least strict criteria (18% versus 4%, respectively). Similarly, over 2× more AVS procedures were classified as lateralized with the least stringent criteria than with the most stringent criteria (60% versus 26%, respectively). Multiple samples were available from ?1 side for 155 AVS procedures. These procedures were classified differently by ?2 right-left sample pairs in 12% to 20% of cases. Thus, different sets of criteria used to interpret AVS in experienced institutions translate into heterogeneous classifications and hence management decisions, for patients with primary aldosteronism. Defining the most appropriate procedures and diagnostic criteria is needed for AVS to achieve optimal performance and fully justify its status as a gold standard. PMID:25646291

    When pulp tissue becomes necrotic in immature teeth, the prognosis of the teeth is compromised. Disinfection of the root(s) presents several challenges including difficulties in cleaning and shaping large canals with open apices, obturation of canals with open apices, and potential root fractures caused by thin and/or weakened root walls. Regenerative endodontic procedures may increase the prognosis of the compromised immature tooth by re-establishment of a functional pulp tissue that fosters continued root development and immune competency. This article reviews the literature related to and discuss considerations for regenerative endodontic procedures and how these procedures may increase the prognosis for immature teeth with necrotic pulp tissue.

    The laser "in vivo" autofluorescence diagnostics is now widely studied and applied in different areas of medicine, such as an oncology, dermatology, etc. Recently we have reported of created new professional multiwave laser diagnostic system (MLDS) for this purpose under the international scientific research and development project #1001 supported by the International Scientific and Technology Center. This presentation lights some results of application of the MLDS in a real clinical practice at Moscow Regional Research and Clinical Institute "MONIKI", Department of Radiology. With the use of MLDS we investigated a skin and oral cavity cancer endogenous fluorescence before, during and after standard radiotherapy treatment. A statistical analysis showed that the best radiotherapy result was achieved for the patients with a small initial porfirines" autofluorescence and a great initial flavines" one from irradiated tumor tissues. It was shown that each radiotherapy procedure has an influence on a tissues" autofluorescence intensity. The tendencies in porfirines" fluorescence during a treatment course can be an additional prognostic factor for the prediction of the efficacy of a radiotherapy treatment. Moreover, it was estimated that a number of non-cancerous skin disease has a typical "cancer" initial autofluorescence, that makes it difficult to distinguish them one from another with the use of only the fluorescence diagnostics, but opens the way to investigate the non-cancerous tissues diseases with the help of tissues endogenous fluorescence phenomenon.

    Primary Immunodeficiencies (PID) are genetically inherited disorders characterized by defects of the immune system, leading to increased susceptibility to infection. Due to the variety of clinical symptoms and the complexity of current diagnostic procedures, accurate diagnosis of PID is often difficult in daily clinical practice. Thanks to the advent of “next generation” sequencing technologies and target enrichment methods, the development of multiplex diagnostic assays is now possible. In this study, we applied a selector-based target enrichment assay to detect disease-causing mutations in 179 known PID genes. The usefulness of this assay for molecular diagnosis of PID was investigated by sequencing DNA from 33 patients, 18 of which had at least one known causal mutation at the onset of the experiment. We were able to identify the disease causing mutations in 60% of the investigated patients, indicating that the majority of PID cases could be resolved using a targeted sequencing approach. Causal mutations identified in the unknown patient samples were located in STAT3, IGLL1, RNF168 and PGM3. Based on our results, we propose a stepwise approach for PID diagnostics, involving targeted resequencing, followed by whole transcriptome and/or whole genome sequencing if causative variants are not found in the targeted exons.

    Minimally invasive gastrointestinal, genitourinary, and gynecological procedures are widely used in the clinical practice for diagnostic and therapeutic purposes. Complications both minor and major are not uncommon with these procedures. Imaging plays an important role in the detection and optimal management of these complications. Familiarity with the clinical and imaging features of these complications by radiologists can help in their timely detection. PMID:25537821

    The primary challenge in the design of an Inertial Confinement Fusion (ICF) power reactor is to make the first wall survive the frequent explosions of the pellets. Westinghouse has proposed a dry wall design consisting of steel tubes coated with tantalum. This report describes the design of a test chamber and two diagnostic procedures for experimentally determining the reliability of the Westinghouse design. The test chamber simulates the x-ray and ion pulse irradiation of the wall due to a pellet explosion. The diagnostics consist of remote temperature sensing and surface deformation measurements. The chamber and diagnostics can also be used to test other first-wall designs.

    It is difficult to diagnose faults and maintain weapon systems because (1) they are highly complex pieces of equipment composed of multiple mechanical, electrical, and hydraulic assemblies, and (2) talented maintenance personnel are continuously being lost through the attrition process. To solve this problem, we developed a portable diagnostic and maintenance aid that uses a knowledge-based expert system. This aid incorporates diagnostics, operational procedures, repair and replacement procedures, and regularly scheduled maintenance into one compact, 18-pound graphics workstation. Drawings and schematics can be pulled up from the CD-ROM to assist the operator in answering the expert system's questions. Work for this aid began with the development of the initial knowledge-based expert system in a fast prototyping environment using a LISP machine. The second phase saw the development of a personal computer-based system that used videodisc technology to pictorially assist the operator. The current version of the aid eliminates the high expenses associated with videodisc preparation by scanning in the art work already in the manuals. A number of generic software tools have been developed that streamlined the construction of each iteration of the aid; these tools will be applied to the development of future systems.

  9. Integrated Diagnostic Analysis of ICF Capsule Performance

    An understanding of the dynamics of imploding Inertial Confinement Fusion (ICF) capsules is crucial to achieve high convergence and gain. The relative roles of laser irradiation, hohlraum drive, and capsule response are intertwined and will be difficult to disentangle unless appropriate diagnostic probes are fielded and their results correlated. In the case of capsule implosions, several currently deployed diagnostics provide important information about the size and shape of the developing hot spot through x-ray self-emission, neutron production and average ion temperature by neutron time-of-flight signals, shell material mix into the hot spot by high-resolution x-ray spectra, and remaining mass during convergent ablation by x-ray backlighting. Obtaining a physically consistent picture of the implosion dynamics requires an integration of these disparate experimental data. This talk describes a three-dimensional model that attempts this integration. Assuming pressure equilibrium at peak compression and invoking simple radiative and equation-of-state relations, the pressure, density and electron temperature are obtained by optimized fitting of the experimental output to simple, global functional forms. The fitting procedure is sufficiently flexible to incorporate typical observational data such as x-ray self-emission, neutron time-of-flight signals, neutron yield, high-resolution x-ray spectra and radiographic images. Once consistency is obtained, many important secondary quantities can be derived such as the fuel areal density, high energy x-ray emission, neutron images, and nuclear activation. This approach has been validated by comparison with radiation-hydrodynamic simulations, producing semi-quantitative agreement and is now routinely used to characterize cryogenic implosion experiments. This talk will provide an overview of the implementation of the model and describe its application to recent experimental data.[4pt] In addition to my collaborators Paul Springer and Scott Sepke, the author would like to thank many scientists for their assistance: J.

    Practical guidelines for the diagnosis of acute pancreatitis are presented so that a rapid and adequate diagnosis can be made. When acute pancreatitis is suspected in patients with acute onset of abdominal pain and tenderness mainly in the upper abdomen, the diagnosis of acute pancreatitis is made on the basis of elevated levels of pancreatic enzymes in the blood and/or urine. Furthermore, other acute abdominal diseases are ruled out if local findings associated with pancreatitis are confirmed by diagnostic imaging. According to the diagnostic criteria established in Japan, patients who present with two of the following three manifestations are diagnosed as having acute pancreatitis: characteristic upper abdominal pain, elevated levels of pancreatic enzymes, and findings of ultrasonography (US), CT or MRI suggesting acute pancreatitis. Detection of elevated levels of blood pancreatic enzymes is crucial in the diagnosis of acute pancreatitis. Measurement of blood lipase is recommended, because it is reported to be superior to all other pancreatic enzymes in terms of sensitivity and specificity. For measurements of the blood amylase level widely used in Japan, it should be cautioned that, because of its low specificity, abnormal high values are also often obtained in diseases other than pancreatitis. The cut-off level of blood pancreatic enzymes for the diagnosis of acute pancreatitis is not able to be set because of lack of sufficient evidence and consensus to date. CT study is the most appropriate procedure to confirm image findings of acute pancreatitis. Elucidation of the etiology of acute pancreatitis should be continued after a diagnosis of acute pancreatitis. In the process of the etiologic elucidation of acute pancreatitis, judgment whether it is gallstone-induced or not is most urgent and crucial for deciding treatment policy including the assessment of whether endoscopic papillary treatment should be conducted or not. The diagnosis of gallstone-induced acute pancreatitis can be made by combining detection of elevated levels of bilirubin, transamylase (ALT, AST) and ALP detected by hematological examination and the visualization of gallstones by US.

    Studies employing high-throughput biological techniques have recently contributed to an improved characterization of human cancers, allowing for novel sub-classification, better diagnostic accuracy, and more precise prognostication. However, requirement of surgical procurement of tissue among other things limits the clinical application of such methods in everyday patient care. Radiographic imaging is routine in clinical practice but is currently histopathology based. The use of routine radiographic imaging provides a potential platform for linking specific imaging traits with specific gene expression patterns that inform the underlying cellular pathophysiology; imaging features could then serve as molecular surrogates that contribute to the diagnosis, prognosis, and likely gene-expression-associated treatment response of various forms of human cancer. This review focuses on high-throughput methods such as microarray analysis of gene expression, their role in cancer research, and in particular, on novel methods of associating gene expression patterns with radiographic imaging phenotypes, known as "radiogenomics." These findings underline a potential future role of both diagnostic and interventional radiologists in genetic assessment of cancer patients with radiographic imaging studies. PMID:19303233

    To reconstruct reliable nuclear medicine-related occupational radiation doses or doses received as patients from radiopharmaceuticals over the last five decades, the authors assessed which radiopharmaceuticals were used in different time periods, their relative frequency of use, and typical values of the administered activity. This paper presents data on the changing patterns of clinical use of radiopharmaceuticals and documents the range of activity administered to adult patients undergoing diagnostic nuclear medicine procedures in the U.S. between 1960 and 2010. Data are presented for 15 diagnostic imaging procedures that include thyroid scan and thyroid uptake; brain scan; brain blood flow; lung perfusion and ventilation; bone, liver, hepatobiliary, bone marrow, pancreas, and kidney scans; cardiac imaging procedures; tumor localization studies; localization of gastrointestinal bleeding; and non-imaging studies of blood volume and iron metabolism. Data on the relative use of radiopharmaceuticals were collected using key informant interviews and comprehensive literature reviews of typical administered activities of these diagnostic nuclear medicine studies. Responses of key informants on relative use of radiopharmaceuticals are in agreement with published literature. Results of this study will be used for retrospective reconstruction of occupational and personal medical radiation doses from diagnostic radiopharmaceuticals to members of the U.S. radiologic technologists' cohort and in reconstructing radiation doses from occupational or patient radiation exposures to other U.S. workers or patient populations.
