A Preliminary Evaluation of Two Behavioral Skills Training Procedures for Teaching Abduction-Prevention Skills to Schoolchildren  

PubMed Central

Although child abduction is a low-rate event, it presents a serious threat to the safety of children. The victims of child abduction face the threat of physical and emotional injury, sexual abuse, and death. Previous research has shown that behavioral skills training (BST) is effective in teaching children abduction-prevention skills, although not all children learn the skills. This study compared BST only to BST with an added in situ training component to teach abduction-prevention skills in a small-group format to schoolchildren. Results showed that both programs were effective in teaching abduction-prevention skills. In addition, the scores for the group that received in situ training were significantly higher than scores for the group that received BST alone at the 3-month follow-up assessment. PMID:16602383

Alien abduction: a medical hypothesis.  

PubMed

In response to a new psychological study of persons who believe they have been abducted by space aliens that found that sleep paralysis, a history of being hypnotized, and preoccupation with the paranormal and extraterrestrial were predisposing experiences, I noted that many of the frequently reported particulars of the abduction experience bear more than a passing resemblance to medical-surgical procedures and propose that experience with these may also be contributory. There is the altered state of consciousness, uniformly colored figures with prominent eyes, in a high-tech room under a round bright saucerlike object; there is nakedness, pain and a loss of control while the body's boundaries are being probed; and yet the figures are thought benevolent. No medical-surgical history was apparently taken in the above mentioned study, but psychological laboratory work evaluated false memory formation. I discuss problems in assessing intraoperative awareness and ways in which the medical hypothesis could be elaborated and tested. If physicians are causing this syndrome in a percentage of patients, we should know about it; and persons who feel they have been abducted should be encouraged to inform their surgeons and anesthesiologists without challenging their beliefs.

Diagnostic Procedures and Management of Dry Eye  

PubMed Central

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

Knee abduction angular impulses during prolonged running with wedged insoles.  

PubMed

Wedged insoles may produce immediate effects on knee abduction angular impulses during running; however, it is currently not known whether these knee abduction angular impulse magnitudes are maintained throughout a run when fatigue sets in. If changes occur, this could affect the clinical utility of wedged insoles in treating conditions such as patellofemoral pain. Thus, the purpose of this study was to determine whether knee abduction angular impulses are altered during a prolonged run with wedged insoles. It was hypothesized that knee abduction angular impulses would be reduced following a prolonged run with wedged insoles. Nine healthy runners participated. Runners were randomly assigned to either a 6-mm medial wedge condition or a 6-mm lateral wedge condition and then ran continuously overground for 30 min. Knee abduction angular impulses were quantified at 0 and 30 min using a gait analysis procedure. After 2 days, participants returned to perform the same test but with the other wedge type. Two-way repeated-measures analysis of variance was used to evaluate main effects of wedge condition and time and interactions between wedge condition and time (? = 0.05). Paired t-tests were used for post hoc analysis (? = 0.01). No interaction effects (p = 0.958) were found, and knee abduction angular impulses were not significantly different over time (p = 0.384). Lateral wedge conditions produced lesser knee abduction angular impulses than medial conditions at 0 min (difference of 2.79 N m s, p = 0.006) and at 30 min (difference of 2.76 N m s, p < 0.001). It is concluded that significant knee abduction angular impulse changes within wedge conditions do not occur during a 30-min run. Additionally, knee abduction angular impulse differences between wedge conditions are maintained during a 30-min run. PMID:23636760

Diagnostic procedures for submucosal tumors in the gastrointestinal tract  

PubMed Central

This review is part one of three, which will present an update on diagnostic procedures for gastrointestinal (GI) submucosal tumors (SMTs). Part two identifies the classification and part three the therapeutic methods regarding GI SMTs. Submucosal tumors are typically asymptomatic and therefore encountered incidentally. Advances in diagnostic tools for gastrointestinal submucosal tumors have emerged over the past decade. The aim of this paper is to provide the readers with guidelines for the use of diagnostic procedures, when a submucosal tumor is suspected. Literature searches were performed to find information on diagnostics for gastrointestinal submucosal tumors. Based on the searches, the optimal diagnostic procedures and specific features of the submucosal tumors could be outlined. Standard endoscppy, capsule endoscopy and push-and-pull enteroscopy (PPE) together with barium contrast X-ray do not alone provide sufficient information, when examining submucosal tumors. Endoscopic ultrasound (EUS), computed tomography (CT), magnetic resonance imaging (MRI) and fluorodeoxyglucose-labeled positron emission tomography (FDG-PET) are recommended as supplementary tools.

Completing fault models for abductive diagnosis  

SciTech Connect

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.

Kinematic mental simulations in abduction and deduction  

PubMed Central

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.

Galactography: the diagnostic procedure of choice for nipple discharge  

SciTech Connect

Galactogrpahy was performed in 204 women with a nipple discharge and the secretion confirmed histopathologically. All 116 intraductal tumors (papilloma, papillomatosis, carcinoma), which were associated with a serous or bloody discharge, were detected preoperatively. A palpable mass had little diagnostic significance, and exfoliative cytology was positive in only 11% (2/18) of the patients with carcinoma. The authors recommend that all patients with a spontaneous bloody or serous discharge from a single lactiferous orifice undergo galactography in addition to physical, cytological, and mammographic examination. Intraductal injection of methylene blue dye will demonstrate the affected duct system to the surgeon and can often make surgery less radical or even unnecessary.

Diagnostic x-ray procedures and risk of leukemia, lymphoma, and multiple myeloma  

SciTech Connect

Exposure to diagnostic x-rays and the risk of leukemia, non-Hodgkin's lymphoma (NHL), and multiple myeloma were studied within two prepaid health plans. Adult patients with leukemia (n = 565), NHL (n = 318), and multiple myeloma (n = 208) were matched to controls (n = 1390), and over 25,000 x-ray procedures were abstracted from medical records. Dose response was evaluated by assigning each x-ray procedure a score based on estimated bone marrow dose. X-ray exposure was not associated with chronic lymphocytic leukemia, one of the few malignant conditions never linked to radiation (relative risk (RR), 0.66). For all other forms of leukemia combined (n = 358), there was a slight elevation in risk (RR, 1.17) but no evidence of a dose-response relationship when x-ray procedures near the time of diagnosis were excluded. Similarly, patients with NHL were exposed to diagnostic x-ray procedures more often than controls (RR, 1.32), but the RR fell to 0.99 when the exposure to diagnostic x-ray procedures within 2 years of diagnosis was ignored. For multiple myeloma, overall risk was not significantly high (RR, 1.14), but there was consistent evidence of increasing risk with increasing numbers of diagnostic x-ray procedures. These data suggest that persons with leukemia and NHL undergo x-ray procedures frequently just prior to diagnosis for conditions related to the development or natural history of their disease. There was little evidence that diagnostic x-ray procedures were causally associated with leukemia or NHL. The risk for multiple myeloma, however, was increased among those patients who were frequently exposed to x-rays.

Pharmacological aspects of the antibiotics used for urological diagnostic procedures.  

PubMed

Surgical antimicrobial prophylaxis is the use of an antibiotic before, during, or shortly after a urological procedure to prevent postoperative infections such as urinary tract or wound infection. The optimal antimicrobial drug must be microbiologically active against the most frequent potential pathogens and have good pharmacological properties. Correct timing of antimicrobial prophylaxis is the first critical issue in determining treatment efficacy. The antibiotic must be administered before the start of the surgical procedure in order to ensure a high tissue level at the time of microbial contamination. If using an oral antibiotic, this must be administered 1-3 hours before the operation and a parenteral antibiotic should be administered at the induction of anaesthesia. The antibiotics potentially useful for antimicrobial prophylaxis are the beta-lactams, cotrimoxazole, fluoroquinolones, and fosfomycin trometamol. The criteria for choosing the optimal antibiotic include an appropriate antimicrobial spectrum, favourable pharmacokinetic parameters (especially good tissue penetration), and elevated safety or tolerability. The use of cotrimoxazole must be restricted due to increasing chemoresistance. Unfortunately fluoroquinolone-based regimens, once the mainstay of prophylaxis guidelines, are increasingly ineffective due to a constant increase in multidrug-resistant (MDR) Gram-negative bacteria. The same concerns apply with regard to the second and third generation cephalosporins that have problems of resistance and, if administered orally, do not sufficiently penetrate prostatic tissue. An appropriate beta-lactam could be an aminopenicillin combined with a beta-lactamase inhibitor. Fosfomycin trometamol can also be a good potential choice due to its elevated activity against MDR Gram-negative bacteria and its favourable pharmacokinetic parameters, including an elevated penetration into prostatic tissue.

Sex Differences in Knee Abduction During Landing  

PubMed Central

Background: Females suffer injuries to the anterior cruciate ligament at rates significantly higher than males. Frontal plane knee motion and load have been identified as major risk factors for anterior cruciate ligament injury and in turn have been examined extensively. Methods: A systematic review of MEDLINE, CINHAL, and SportDISCUS was performed (1982–June 2010). Criteria for inclusion were the use of 3-dimensional analyses of frontal plane knee motion and moments during landing between males and females. Results: Twenty-seven studies met the inclusion criteria and were reviewed. Sixty-three percent of included studies identified sex differences in knee abduction when landing across a variety of landing conditions. Conclusions: Females appear to land with increased knee abduction motion compared with males in most biomechanics studies. PMID:23016030

Prospective Comparison of Stereotactic Core Biopsy and Surgical Excision as Diagnostic Procedures for Breast Cancer Patients  

PubMed Central

Objective To determine whether stereotactic core biopsy (SCNB) is the diagnostic method of choice for all mammographic abnormalities requiring tissue sampling. Summary Background Data Stereotactic core needle biopsy decreases the cost of diagnosis, but its impact on the number of surgical procedures needed to complete local therapy has not been studied in a large, unselected patient population. Methods A total of 1,852 mammographic abnormalities in 1,550 consecutive patients were prospectively categorized for level of cancer risk and underwent SCNB or diagnostic needle localization and surgical excision. Diagnosis, type of cancer surgery, and number of surgical procedures to complete local therapy were obtained from surgical and pathology databases. Results The malignancy rate was 24%. Surgical biopsy patients were older, more likely to have cancer, and more likely to be treated with breast-conserving therapy than those in the SCNB group. For all types of lesions, regardless of degree of suspicion, patients diagnosed by SCNB were almost three times more likely to have one surgical procedure. However, for patients treated with lumpectomy alone, the number of surgical procedures and the rate of negative margins did not differ between groups. Conclusions Stereotactic core needle biopsy is the diagnostic procedure of choice for most mammographic abnormalities. However, for patients undergoing lumpectomy without axillary surgery, it is an extra invasive procedure that does not facilitate obtaining negative margins. PMID:11303136

Memory distortion in people reporting abduction by aliens.  

PubMed

False memory creation was examined in people who reported having recovered memories of traumatic events that are unlikely to have occurred: abduction by space aliens. A variant of the Deese/Roediger-McDermott paradigm (J. Deese. 1959; H. L. Roediger III & K. B. McDermott, 1995) was used to examine false recall and false recognition in 3 groups: people reporting recovered memories of alien abduction. people who believe they were abducted by aliens but have no memories, and people who deny having been abducted by aliens. Those reporting recovered and repressed memories of alien abduction were more prone than control participants to exhibit false recall and recognition. The groups did not differ in correct recall or recognition. Hypnotic suggestibility, depressive symptoms, and schizotypic features were significant predictors of false recall and false recognition.

Procedural costs of digital vs. analog archiving of diagnostic cardiac catheterizations.  

PubMed

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.

Activity based costing of diagnostic procedures at a nuclear medicine center of a tertiary care hospital  

PubMed Central

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

Abduction Motion Analysis of Hemiplegic Shoulders with a Fluoroscopic Guide  

PubMed Central

Purpose We investigated the usefulness of video based, fluoroscopically guided abduction motion analysis of hemiplegic shoulders. Patients and Methods Twenty-two stroke patients with Brunnstrom stages 3-4 (Group 1) or 5-6 (Group 2) were enrolled in this study. Patients with shoulder pain and significant spasticity (MAS 2) were excluded. We recorded motion pictures of the abductions of affected and unaffected shoulder joints under an AP fluoroscopic guide. Lateral scapular slide distances (D1: T2-superior angle, D2: T3-scapular spine, D3: T7-inferior angle) were measured at 30°, 60°, 90° during glenohumeral abduction in a captured photographic image. The angles of scapular rotation and trajectory (stromotion) of the humeral head center, relative to the 3rd thoracic spine in the abduction motion were analyzed. Results In Group 1, a significant difference was found in the lateral scapular slide distance between the affected and sound sides. However, no significant side to side difference was found in Group 2. Scapular angles in abduction were also increased in Group 1. Patients with a more synergistic movement pattern showed less scapular stabilizing muscle activity and, instead, exhibited a compensatory "shrugging" like motion accomplished by spinal tilting. Conclusion The present findings support the notion that the above parameters of fluoroscopically guided shoulder abduction motion analysis correlate well with clinical findings. These parameters should be useful for evaluations of hemiplegic shoulder biomechanics. PMID:17461523

Establishment of diagnostic reference levels in computed tomography for select procedures in Pudhuchery, India.  

PubMed

Computed tomography (CT) scanner under operating conditions has become a major source of human exposure to diagnostic X-rays. In this context, weighed CT dose index (CTDIw), volumetric CT dose index (CTDIv), and dose length product (DLP) are important parameter to assess procedures in CT imaging as surrogate dose quantities for patient dose optimization. The current work aims to estimate the existing dose level of CT scanner for head, chest, and abdomen procedures in Pudhuchery in south India and establish dose reference level (DRL) for the region. The study was carried out for six CT scanners in six different radiology departments using 100 mm long pencil ionization chamber and polymethylmethacrylate (PMMA) phantom. From each CT scanner, data pertaining to patient and machine details were collected for 50 head, 50 chest, and 50 abdomen procedures performed over a period of 1 year. The experimental work was carried out using the machine operating parameters used during the procedures. Initially, dose received in the phantom at the center and periphery was measured by five point method. Using these values CTDIw, CTDIv, and DLP were calculated. The DRL is established based on the third quartile value of CTDIv and DLP which is 32 mGy and 925 mGy.cm for head, 12 mGy and 456 mGy.cm for chest, and 16 mGy and 482 mGy.cm for abdomen procedures. These values are well below European Commission Dose Reference Level (EC DRL) and comparable with the third quartile value reported for Tamil Nadu region in India. The present study is the first of its kind to determine the DRL for scanners operating in the Pudhuchery region. Similar studies in other regions of India are necessary in order to establish a National Dose Reference Level. PMID:24600173

Past-life identities, UFO abductions, and satanic ritual abuse: the social construction of memories.  

PubMed

People sometimes fantasize entire complex scenarios and later define these experiences as memories of actual events rather than as imaginings. This article examines research associated with three such phenomena: past-life experiences, UFO alien contact and abduction, and memory reports of childhood ritual satanic abuse. In each case, elicitation of the fantasy events is frequently associated with hypnotic procedures and structured interviews which provide strong and repeated demands for the requisite experiences, and which then legitimate the experiences as "real memories." Research associated with these phenomena supports the hypothesis that recall is reconstructive and organized in terms of current expectations and beliefs. PMID:7960296

Developing an automated database for monitoring ultrasound- and computed tomography-guided procedure complications and diagnostic yield.  

PubMed

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.

Monte Carlo estimation of patient effective dose in diagnostics procedures using 131I  

NASA Astrophysics Data System (ADS)

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.

Metadata requirements for results of diagnostic imaging procedures: a BIIF profile to support user applications  

NASA Astrophysics Data System (ADS)

A visible digital image is rendered from a set of digital image data. Medical digital image data can be stored as either: (a) pre-rendered format, corresponding to a photographic print, or (b) un-rendered format, corresponding to a photographic negative. The appropriate image data storage format and associated header data (metadata) required by a user of the results of a diagnostic procedure recorded electronically depends on the task(s) to be performed. The DICOM standard provides a rich set of metadata that supports the needs of complex applications. Many end user applications, such as simple report text viewing and display of a selected image, are not so demanding and generic image formats such as JPEG are sometimes used. However, these are lacking some basic identification requirements. In this paper we make specific proposals for minimal extensions to generic image metadata of value in various domains, which enable safe use in the case of two simple healthcare end user scenarios: (a) viewing of text and a selected JPEG image activated by a hyperlink and (b) viewing of one or more JPEG images together with superimposed text and graphics annotation using a file specified by a profile of the ISO/IEC Basic Image Interchange Format (BIIF).

Hospital discharge diagnostic and procedure codes for upper gastro-intestinal cancer: how accurate are they?  

PubMed Central

Background Population-level health administrative datasets such as hospital discharge data are used increasingly to evaluate health services and outcomes of care. However information about the accuracy of Australian discharge data in identifying cancer, associated procedures and comorbidity is limited. The Admitted Patients Data Collection (APDC) is a census of inpatient hospital discharges in the state of New South Wales (NSW). Our aim was to assess the accuracy of the APDC in identifying upper gastro-intestinal (upper GI) cancer cases, procedures for associated curative resection and comorbidities at the time of admission compared to data abstracted from medical records (the ‘gold standard’). Methods We reviewed the medical records of 240 patients with an incident upper GI cancer diagnosis derived from a clinical database in one NSW area health service from July 2006 to June 2007. Extracted case record data was matched to APDC discharge data to determine sensitivity, positive predictive value (PPV) and agreement between the two data sources (?-coefficient). Results The accuracy of the APDC diagnostic codes in identifying site-specific incident cancer ranged from 80-95% sensitivity. This was comparable to the accuracy of APDC procedure codes in identifying curative resection for upper GI cancer. PPV ranged from 42-80% for cancer diagnosis and 56-93% for curative surgery. Agreement between the data sources was >0.72 for most cancer diagnoses and curative resections. However, APDC discharge data was less accurate in reporting common comorbidities - for each condition, sensitivity ranged from 9-70%, whilst agreement ranged from ??=?0.64 for diabetes down to ??

Retrospective Evaluation of Standard Diagnostic Procedures in Identification of the Causes of New-Onset Syndrome of inappropriate Antidiuresis  

PubMed Central

Background: Many diagnostic procedures are conducted in patients with syndrome of inappropriate antidiuresis (SIAD). However, the contribution in identification of the cause of SIAD remains unknown. Methods: The study was conducted at Kaohsiung Veterans General Hospital in southern Taiwan. From January 2000 to December 2009, medical records of 439 adult patients hospitalized for new-onset SIAD at a single center were retrospectively collected. All diagnostic procedures during hospitalization were divided into four groups: chest/lung, central nervous system, abdomen, and bone marrow to evaluate their positive rate leading to the cause of SIAD. Factors associated with “procedures leading to the cause” were also analyzed to improve efficacy of survey. Results: Cause of SIAD was identified in 267 (60.8%). Of them, 150 were pulmonary disorders, 44 were drugs, 37 were central nervous system disorders, 32 were malignancy and 4 were post-surgery. Survey for chest/lung, central nervous system, abdomen, and bone marrow were performed in 96.6%, 29.2%, 38.0% and 3.6% of patients, respectively; positive findings leading to the cause of SIAD were 39.6%, 12.5%, 5.3% and 6.3%, respectively. Among the diagnostic procedures, chest x-ray (424/439, 96.6%) was most frequently performed with the highest identification rate of 34.7% (147 cases). Major significant independent factors that associated with “procedure leading to a cause” were: absence of SIAD-associated drug history, presence of fever/chills, and presence of respiratory symptoms. Cause of SIAD became evident later during the follow-up period in 10 of 172 (5.8%) patients who were initially thought to be cause-unknown. Malignancy was the cause for 5 cases and pulmonary tuberculosis was for the other five. Eight of these causes became evident within one year after the diagnosis of SIAD. Conclusions: SIAD with unidentified causes were prevalent. Current diagnostic procedures remain not satisfying in determining the cause of SIAD, but chest radiograph did demonstrate higher diagnostic rate, especially in patients presented with fever, chills, respiratory symptoms, and without SIAD-associated drug history. Patients with unidentified cause should be followed for at least one year when most hidden causes (e.g. malignancy and tuberculosis) become obvious. PMID:24465165

A Neural Approach to Abductive Multi-adjoint Reasoning  

Microsoft Academic Search

A neural approach to propositional multi-adjoint logic pro- gramming was recently introduced. In this paper we extend the neural approach to multi-adjoint deduction and, furthermore, modify it to cope with abductive multi-adjoint reasoning, where adaptations of the uncer- tainty factor in a knowledge base are carried out automatically so that an umber of given observations can be adequately explained. 1I

Hip Muscle Activity during Isometric Contraction of Hip Abduction  

PubMed Central

[Purpose] This study aimed to determine the effect of varying hip flexion angle on hip muscle activity during isometric contraction in abduction. [Subjects] Twenty-seven healthy men (mean age=21.5?years, SD=1.2) participated in this study. [Methods] Surface electromyography (EMG) was recorded of the upper portion of the gluteus maximus (UGM), lower portion of the gluteus maximus (LGM), tensor fasciae latae (TFL), and gluteus medius (GMed) during isometric contraction under two measurement conditions: hip flexion angle (0, 20, 40, 60, and 80 degrees) and abduction of the hip joint at 20, 40, 60, and 80% maximum strength. Integrated EMG (IEMG) were calculated and normalized to the value of maximum voluntary contraction (MVC). [Results] Results indicated that the IEMG of both the UGM and LGM increased significantly with increases in hip flexion angle, whereas the IEMG of the TFL decreased significantly. The maximum activities of the UGM and the LGM were 85.7 ± 80.8%MVC and 38.2 ± 32.9%MVC at 80 degrees of hip flexion, respectively, and that of the TFL was 71.0 ± 39.0%MVC at 40 degrees of hip flexion. [Conclusion] The IEMG of the GMed did not change with increases in hip flexion angle. Hip flexion angle affected the activity of the GM and TFL during isometric contraction in abduction.

Comparison of two types of adult phantoms in terms of organ doses from diagnostic CT procedures  

NASA Astrophysics Data System (ADS)

The rapidly increasing number of diagnostic computed tomography (CT) procedures in the recent decades has spurred heightened concern over the potential risk to patients. Although an accurate organ dose assessment tool has now become highly desirable, existing software packages depend on stylized computational phantoms that were originally developed more than 40 years ago, exhibiting very large discrepancies when compared with phantoms that are anatomically realistic. However, past comparative studies did not focus on CT protocols for adult patients. This study was designed to quantitatively compare two types of phantoms, the stylized phantoms and a pair of recently developed RPI-adult male and adult female (RPI-AM and RPI-AF) phantoms, for various CT scanning protocols involving the chest, abdomen-pelvis and chest-abdomen-pelvis. Organ doses were based on Monte Carlo simulations using the MCNPX code and a detailed CT scanner model for the GE LightSpeed 16. Results are presented as ratios of organ doses from the stylized phantoms to those from the RPI phantoms. It is found that, for most organs contained in the scan volume, the ratios were within the range of 0.75-1.16. However, the stomach doses are significantly different and the ratio is found to be up to 1.86 in male phantoms and 2.29 in the female phantoms due to the anatomical differences between the two types of phantoms. Organs that lie near a scan boundary also exhibit a significant relative difference in organ doses between the two types of phantoms. This study concludes that, due to relatively low x-ray energies, CT doses are very sensitive to organ shape, size and position, and thus anatomically realistic phantoms should be used to avoid the dose uncertainties caused by the lack of anatomical realism. The new phantoms, such as the RPI-AM and AF phantoms that are designed using advanced surface meshes, are deformable and will make it possible to match the anatomy of a specific patient leading to further improvement in dose and risk assessments for patients undergoing CT examinations.

In this paper, we propose a reconstruction of logic-based approaches to abductive reasoning in terms of ampliative adaptive logics. The ad- vantages of this reconstruction are important: the resulting logics have a proper proof theory (that leads to justied conclusions even for undecid- able fragments), they nicely integrate deductive and abductive steps, and they are much closer to natural reasoning

Hip Abduction Can Prevent Posterior Edge Loading of Hip Replacements  

PubMed Central

Edge loading causes clinical problems for hard-on-hard hip replacements, and edge loading wear scars are present on the majority of retrieved components. We asked the question: are the lines of action of hip joint muscles such that edge loading can occur in a well-designed, well-positioned acetabular cup? A musculoskeletal model, based on cadaveric lower limb geometry, was used to calculate for each muscle, in every position within the complete range of motion, whether its contraction would safely pull the femoral head into the cup or contribute to edge loading. The results show that all the muscles that insert into the distal femur, patella, or tibia could cause edge loading of a well-positioned cup when the hip is in deep flexion. Patients frequently use distally inserting muscles for movements requiring deep hip flexion, such as sit-to-stand. Importantly, the results, which are supported by in vivo data and clinical findings, also show that risk of edge loading is dramatically reduced by combining deep hip flexion with hip abduction. Patients, including those with sub-optimally positioned cups, may be able to reduce the prevalence of edge loading by rising from chairs or stooping with the hip abducted. © 2013 Orthopaedic Research Society Published by Wiley Periodicals, Inc.

Muscular load characterization during isometric shoulder abductions with varying force.  

PubMed

This study sought to characterize muscle loading and fatigue during static shoulder abductions with varying force. In a supine posture, participants maintained fixed shoulder abductions against a time-varying external resistance, generated by a dynamometer-spring mechanism. Patterns (cumulative distribution) of the external resistance were varied by selecting different 10th and 90th percentiles of the distribution. Dynamometer angular velocities were also varied, to reflect different rates of cyclic muscle contraction. The degree of local fatigue development was assessed by common measures, including endurance time, strength reduction, and perceived discomfort. Myoelectric (EMG) signals were continuously obtained from the middle deltoid muscle throughout experimental exercise (60min max). Changes in EMG root-mean-square (RMS) and spectral measures (derived from 1-s windows at peaks in the cyclic contractions) were used as manifestations of muscle fatigue. For each minute, the RMS signal was further reduced using two methods, the cumulative probability distribution of EMG (CPDE) and exposure variation analysis (EVA). The former resulted in three percentile values (10th, 50th, and 90th), whereas the latter method resulted in 10 different measures (grouped by EMG activity level and duration). A main finding of the study was the applicability of several common fatigue indicators for these cyclic, repetitive exertions. Overall, the use of CPDE and EVA to characterize task differences and predict muscle fatigue was found to have limited value. PMID:17382561

The Australian experiment: the use of evidence based medicine for the reimbursement of surgical and diagnostic procedures (1998-2004)  

PubMed Central

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.

Critical appraisal of angioscintigraphy as a diagnostic procedure in cerebrovascular disease.  

PubMed

In order to assess the diagnostic usefulness of combined functional and morphological isotopic investigations of brain vascularization after intravenous injection of a bolus 99mTc pertechnetate, the authors explored, besides a control group, patients with acute cerebrovascular disease, angiomas, aneurysms and intracerebral hematomas. Combined flow evaluation and visualization of the intracerebral bolus transit was highly effective in patients with cerebrovascular disease. Angiomas with a diameter of 2 cm or more are always visible, the abnormal vascularization of the affected hemisphere being correctly evaluated. Cerebral aneurysms are frequently missed by angioscintigraphy. Intracerebral hematoma generally gives false negative results. PMID:888673

Foetal Radiation Dose and Risk from Diagnostic Radiology Procedures: A Multinational Study  

PubMed Central

In diagnostic radiology examinations there is a benefit that the patient derives from the resulting diagnosis. Given that so many examinations are performed each year, it is inevitable that there will be occasions when an examination(s) may be inadvertently performed on pregnant patients or occasionally it may become clinically necessary to perform an examination(s) on a pregnant patient. In all these circumstances it is necessary to request an estimation of the foetal dose and risk. We initiated a study to investigate fetal doses from different countries. Exposure techniques on 367 foetuses from 414 examinations were collected and investigated. The FetDoseV4 program was used for all dose and risk estimations. The radiation doses received by the 367 foetuses ranges: <0.001–21.9?mGy depending on examination and technique. The associated probability of induced hereditary effect ranges: <1 in 200000000 (5 × 10?9) to 1 in 10000 (1 × 10?4) and the risk of childhood cancer ranges <1 in 12500000 (8 × 10?8) to 1 in 500 (2 × 10?3). The data indicates that foetal doses from properly conducted diagnostic radiology examinations will not result in any deterministic effect and a negligible risk of causing radiation induced hereditary effect in the descendants of the unborn child.

Procedures to minimize diagnostic x-ray exposure of the human embryo and fetus. Final report  

SciTech Connect

The recommendations published here are intended for the attending physician, the radiologist, the technologist, and the patient, delineating their respective roles in optimizing the x-ray exposure of pregnant or potentially pregnant women. These recommendations emphasize the necessity for attending physicians to determine whether or not their patients might be pregnant and to use this information in deciding on the need for an x-ray examination. The recommendations also stress the need to reduce x-ray exposure throughout gestation, and suggest ways in which this can be accomplished. X-ray exposure of the developing embryo and fetus has been a matter of concern for many years. Several national and international organizations have developed guidelines or policy statements on the subject. The BRH recommendations are expansions of the conceptual foundations provided by these other organizations, and they clarify the ways in which medical radiation exposure can be minimized without compromising the medical care of the mother. These recommendations are based on the principle that unnecessary or unproductive medical radiation exposure should be avoided or reduced to the extent possible, while preserving and improving the anticipated benefits of radiological diagnostic information. As with all medical applications of ionizing radiation, the physician's decision to obtain a diagnostic x-ray examination of a pregnant or potentially pregnant patient should be based on the judgment that the medical information obtained is likely to be important for appropriate patient management.

Work-related stress and bullying: gender differences and forensic medicine issues in the diagnostic procedure  

PubMed Central

Background The attention of international agencies and scientific community on bullying and work-related stress is increasing. This study describes the gender differences found in victims of bullying and work-related stress in an Italian case series and analyzes the critical issues in the diagnostic workup. Methods Between 2001 and 2009 we examined 345 outpatients (148 males, 197 females; mean age: 41 ± 10.49) for suspected psychopathological work-related problems. Diagnosis of bullying was established using international criteria (ICD-10 and DSM-IV). Results After interdisciplinary diagnostic evaluation (Occupational Medicine Unit, Psychology and Psychiatry Service), the diagnosis of bullying was formulated in 35 subjects, 12 males and 23 females (2 cases of Post-Traumatic Stress Disorder and 33 of Adjustment Disorder). Fifty-four (20 males, 34 females) suffered from work-related anxiety, while work-unrelated Adjustment Disorder and other psychiatric disorders were diagnosed in 7 and 112 subjects, respectively. Women between 34 and 45 years showed a high prevalence (65%) of "mobbing syndrome" or other work-related stress disorders. Conclusions At work, women are more subject to harassment (for personal aspects related to emotional and relational factors) than men. The knowledge of the phenomenon is an essential requisite to contrast bullying; prevention can be carried out only through effective information and training of workers and employers, who have the legal obligation to preserve the integrity of the mental and physical status of their employees during work.

[The effect of performance of diagnostic and therapeutic procedures on successful treatment of hemopneumothorax in isolated thoracic trauma].  

PubMed

Influence of performed diagnostic and therapeutic procedures on the outcome of the treatment of traumatic hemopneumothorax during isolated chest trauma. The aim of this study is the assessment of the influence of performed diagnostic and therapeutic procedures on the outcome of hemopneumothorax as a part of isolated chest trauma. The main group consists of 51 patients with hemopneumothorax. Patients with pneumothorax without effusion represent the first control group; the second control group consist of patients treated because of iatrogenic pneumothorax. In the main and control groups the analysis of clinical, roentgenographic and functional parameters was made, together with the analysis of particular therapeutic procedures, the estimation of the success of the treatment was based on roentgenographic and functional parameters. The higher incidence of hemopneumothorax compared with control groups during chest trauma in the analyzed material is statistically significant. The occurrence of bilateral hemopneumothorax in 10% of cases emphasizes the need of adequate roentgenographic assessment of injured patients. Regardless of the intensity of the trauma, symptoms do not always indicate the existence of hemopneumothorax. The number of fractured ribs is not of significant importance in terms of the occurrence of hemopneumothorax or pneumothorax. Severe dyspnea can be accompanied even with a smaller collapse of the lung independently of the amount of blood in the pleural cavity. Oxygenation in the arterial blood is impaired with the great and small pulmonary collapse. Hemodynamic disorders existed in 14% all cases. The higher frequency of operative treatment in the main group is statistically significant. The majority of cases of traumatic hemopneumothorax can be successfully treated by the conservative treatment. Accompanying complications do not have greater influence on the outcome. PMID:8975526

Degree of Vertical Integration Between the Undergraduate Program and Clinical Internship With Respect to Cervical and Cranial Diagnostic and Therapeutic Procedures Taught at the Canadian Memorial Chiropractic College  

PubMed Central

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

Criminal profiling as a plotting activity based on abductive processes.  

PubMed

In this article the authors analyze the nature and aims of criminal profiling from a theoretical point of view. The need to become increasingly "scientific" has given rise to the modern approaches of profiling, which have been particularly successful in cases of serial homicides and sex crimes, given that compulsive (perverse) acts, because of their ritual nature, have been described as being more easily foreseeable and presumably linkable to the psychological and even personal characteristics of a given criminal. On this basis, the authors analyze profiling from an epistemological point of view and show how, in the concrete activity of profiling, profilers depart from the "certainty" of the scientific models (those that are based on deductive-inductive processes); the epistemological basis of reasoning changes as there is no longer an induction-deduction model but rather an abductive model (as conceived and explained by Peirce) in which the importance of plotting (the weaving of a narrative) becomes greater.

Smart on-board diagnostic decision trees for quantitative aviation equipment and safety procedures validation  

NASA Astrophysics Data System (ADS)

The current trend in high-accuracy aircraft navigation systems is towards using data from one or more inertial navigation subsystem and one or more navigational reference subsystems. The enhancement in fault diagnosis and detection is achieved via computing the minimum mean square estimate of the aircraft states using, for instance, Kalman filter method. However, this enhancement might degrade if the cause of a subsystem fault has some effect on other subsystems that are calculating the same measurement. One instance of such case is the tragic incident of Air France Flight 447 in June, 2009 where message transmissions in the last moment before the crash indicated inconsistencies in measured airspeed as reported by Airbus. In this research, we propose the use of mathematical aircraft model to work out the current states of the airplane and in turn, using these states to validate the readings of the navigation equipment throughout smart diagnostic decision tree network. Various simulated equipment failures have been introduced in a controlled environment to proof the concept of operation. The results have showed successful detection of the failing equipment in all cases.

Data-Driven Abductive Discovery in the Earth Sciences (Invited)  

NASA Astrophysics Data System (ADS)

Traditional pathways to discovery in the Earth sciences rely on inductive and deductive approaches, by which patterns and phenomena in nature are discovered first, and observations and modeling to test causal hypotheses follow. These powerful methods have proven successful in documenting and comprehending many aspects of the natural world, but they are inherently less efficient at discovering new complex patterns that require synthesis of diverse types of data. Consequently, such gradual global processes as plate tectonics and climate change required decades of integrated data synthesis preceding discovery of critical Earth phenomena. Vast but largely untapped Earth science data resources offer a potentially revolutionary alternative 'abductive' approach to investigate Earth's co-evolving geo- and biospheres--a systematic data-driven search for accelerated discovery of hidden patterns in the data resources of a dozen different disciplines. Today's Earth science enterprises generate terabytes per day of new data, yet these vast resources are woefully underutilized because they are not linked into a single platform. We advocate the implementation of data infrastructure and interrogation strategies that link existing and new data resources and methods in mineralogy, paleontology, proteomics, irreversible thermodynamics, geodynamics, and geochronology, coupled with newly adapted statistical analysis and visualization capabilities--a new kind of open-access 'scientific instrument' that could transform the Earth sciences. Recent 'brute force' studies of variations in minerals of beryllium, cobalt, mercury, and molybdenum through deep time demonstrate the potential of this concept as a means to search for critical resources; generate insights regarding the co-evolution of ocean chemistry and microbial metabolism; uncover evidence for the timing and rates of near-surface oxygenation; and document subtle ongoing feedbacks between terrestrial life, weathering, soils, and climate. Abductive discovery could thus become a model for a 21st-century, data-driven science that exploits the tremendous opportunities represented by the vast and growing explosion of Earth science data.

Frequency of use of diagnostic and manual therapeutic procedures of the spine currently taught at the Canadian Memorial Chiropractic College: A preliminary survey of Ontario chiropractors. Part 2 - procedure usage rates  

PubMed Central

Objective: The purpose of this study was to determine which diagnostic and therapeutic procedures of the spine are most commonly utilized by chiropractors practicing in Ontario, based on a list of currently taught procedures at CMCC. In Part 1 of this study (published previously), the demographics and practice patterns of the respondents were presented. Part 2 of this study (presented here) reports on the utilization rates of spinal diagnostic and therapeutic procedures by the respondents. Methods: The study consisted of a paper-based survey that was sent to 500 randomly selected Ontario chiropractors who responded confidentially. Survey questions inquired into demographic and practice style characteristics as well as the frequency with which spinal diagnostic and therapeutic procedures were performed. Results: There were 108 respondents to the survey, giving a response rate of 22.4%. Frequency of use of diagnostic procedures fell into three broad categories: (i) those tests that are almost always performed, (ii) those tests that are almost always performed by two-thirds to one-half of patients, and (iii) those tests that are virtually never used. By comparison, respondents utilized the same therapeutic procedures for patients care less consistently. Conclusions: Despite a low response rate, respondents reported mostly relying on static and motion palpation, joint play, neurological tests, and ranges of motion when assessing their patients. Due to a low response rate, the results of this study may not be generalizable to all Ontario chiropractors. PMID:23754862

Sleep paralysis, sexual abuse, and space alien abduction.  

PubMed

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

Longitudinal Sex Differences during Landing in Knee Abduction in Young Athletes  

PubMed Central

Purpose The objective of this study was to determine if biomechanical and neuromuscular risk factors related to abnormal movement patterns increased in females, but not males, during the adolescent growth spurt. Methods 315 subjects participated in two testing sessions approximately one year apart. Male and female subjects were classified based on their maturation status as pubertal or post-pubertal. Three trials of a drop vertical jump (DVJ) were collected. Maximum knee abduction angle and external moments were calculated during the DVJ deceleration phase using a 3D motion analysis system. Changes in knee abduction from the first to second year were compared among four subject groups (female pubertal, female post-pubertal, male pubertal and male post-pubertal). Results There were no sex differences in peak knee abduction angle or moment during DVJ between pubertal males and females (p>0.05). However, pubertal females increased peak abduction angle from the first to second year (p<0.001), while males demonstrated no similar change (p=0.90) in the matched developmental stages. Following puberty, the peak abduction angle and moment were greater in females relative to males (angle: female -9.3±5.7°, male -3.6±4.6°, p<0.001; moment: female:-21.9±13.5 Nm, male:-13.0±12.0 Nm, p=0.017). Conclusion This study identified, through longitudinal analyses, that knee abduction angle was significantly increased in pubertal females during rapid adolescent growth, while males showed no similar change. In addition, knee abduction motion and moments were significantly greater for subsequent year in young female athletes, following rapid adolescent growth, compared to males. The combination of longitudinal, sex and maturational group differences indicate that early puberty appears to be a critical phase related to the divergence of increased ACL injury risk factors.

Acceptance of general personality interpretations prior to and after receipt of diagnostic feedback supposedly based on psychological, graphological, and astrological assessment procedures.  

PubMed

There was no difference in the acceptance of a general personality interpretation supposedly based on psychological, graphological, or astrological assessment procedures. Ss told that their general personality interpretation was based on one of the three assessment procedures, however, accepted the interpretation to a greater degree than did Ss told the interpretation was "generally true of people." S faith in all assessment procedures and perceived diagnostician skill increased significantly from before to after receipt of the diagnostic feedback. Ss elicited a halo response after they had received the interpretation, such that they generated a highly consistent positive (or negative) view of the assessment procedures and diagnostician skills. Implications of results from this acceptance paradigm were discussed for diagnosticians and therapists. PMID:1262486

Nuclear Medicine Practices in the 1950s through the Mid-1970s and Occupational Radiation Doses to Technologists from Diagnostic Radioisotope Procedures.  

PubMed

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

Infantile esotropia with cross-fixation, inability to abduct, and underlying horizontal gaze palsy with progressive scoliosis.  

PubMed

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.

Degree of Vertical Integration Between the Undergraduate Program and Clinical Internship with Respect to Lumbopelvic Diagnostic and Therapeutic Procedures Taught at the Canadian Memorial Chiropractic College  

PubMed Central

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

[First guidelines of Croatian interest group in diagnosing and treating lower back and radicular pain using minimally invasive diagnostic and therapeutic procedures].  

PubMed

Low back and radicular pain recently became a major public health problem. Medical expenses in general, and surgical procedures associated with overall care for the lower back pain are high and growing. Furthermore, these two chronic pain conditions are also leading causes for missed workdays. Degenerative changes of the intervertebral disc, facet joints, sacroiliac joint or disc herniation as described during imaging diagnostics may or may not be the cause of patients' lower back pain. Diagnostic blocks often precede further interventions in order to confirm or dispute a source of the lower back pain. Chronic lower back pain caused by painful intervertebral disc should be treated using biacuplasty. If the pain of the lumbar spine is caused by facet joints or sacroiliac joint, patient can be offered neuroablative procedures using radiofrequency. In cases where the low back and radicular pain are caused by the central and foraminal spinal stenosis patients are advised epidural steroid injections, unless claudications are present. Patients suffering from the chronic radicular pain may be treated with various nucleoplasty procedures or they may be offered percutaneous radiofrequent neuromodulation. The purpose of above advised procedures is to relieve patients' pain, allow optimal physical therapy, and improved functional capacity, consequently providing better quality of life. PMID:23991486

Shoulder abduction-induced reductions in reaching work area following hemiparetic stroke: neuroscientific implications  

PubMed Central

A stroke-related loss of corticospinal and corticobulbar pathways is postulated to result in an increased use of remaining neural substrates such as bulbospinal pathways as individuals with stroke are required to generate greater volitional shoulder abduction torques. The effect of shoulder abduction on upper extremity reaching range of motion (work area) was measured in 18 individuals with stroke using the Arm Coordination Training 3-D (ACT3D) device. This robotic system is capable of quantifying movement kinematics when a subject attempts to reach while simultaneously generating various levels of active shoulder abduction torque. We have provided data demonstrating an incremental increase of abnormal coupling of elbow flexion for greater levels of shoulder abduction in the paretic limb that results in a reduction in available work area as a function of active limb support. The progressive increase in the expression of abnormal shoulder/elbow coupling can be explained by a progressive reliance on the indirect cortico-bulbospinal connections that remain in individuals following a stroke-induced brain injury.

Evaluation of movements of lower limbs in non-professional ballet dancers: hip abduction and flexion  

PubMed Central

Background The literature indicated that the majority of professional ballet dancers present static and active dynamic range of motion difference between left and right lower limbs, however, no previous study focused this difference in non-professional ballet dancers. In this study we aimed to evaluate active movements of the hip in non-professional classical dancers. Methods We evaluated 10 non professional ballet dancers (16-23 years old). We measured the active range of motion and flexibility through Well Banks. We compared active range of motion between left and right sides (hip flexion and abduction) and performed correlation between active movements and flexibility. Results There was a small difference between the right and left sides of the hip in relation to the movements of flexion and abduction, which suggest the dominant side of the subjects, however, there was no statistical significance. Bank of Wells test revealed statistical difference only between the 1st and the 3rd measurement. There was no correlation between the movements of the hip (abduction and flexion, right and left sides) with the three test measurements of the bank of Wells. Conclusion There is no imbalance between the sides of the hip with respect to active abduction and flexion movements in non-professional ballet dancers. PMID:21819566

The ACIST power injection system reduces the amount of contrast media delivered to the patient, as well as fluoroscopy time, during diagnostic and interventional cardiac procedures.  

PubMed

The ACIST injection system is an automatic power injection device that allows for online control of injection rate and volume of contrast. Limited data is available whether this technology allows reducing use of contrast and fluoroscopy time. Accordingly, we compared the use of this system to manual injection among 450 consecutive patients who underwent diagnostic coronary angiography and/or angioplasty who were randomly assigned to either manual contrast injection (control; n=198) or to the ACIST system (study group; n=252). The amount of contrast, fluoroscopy and total procedural times were recorded for each patient. In the diagnostic group, the mean total amount of contrast (including wasted) was reduced by 63% when the ACIST was used compared to control (100+/-42 ml versus 163+/-56 ml; P<0.001, respectively). When only the net amount of contrast delivered to the patient was considered, the differences were smaller (20%, P=0.004). During angioplasty, the amount of contrast was also lower in the ACIST group (206+/-65 versus 230+/-69, P=0.008), whereas no difference were noted in net amount of contrast. Fluoroscopy time was significantly shorter in the ACIST group compared to control both during diagnostic catheterization (4.7+/-3.5 min versus 6.3+/-5.5 min, respectively; P=0.014), and angioplasty (16.7+/-9.1 min versus 19.6+/-12.4 min, respectively; P=0.05). Routine utilization of the ACIST system during diagnostic and interventional procedure significantly reduced the total amount of contrast media used and fluoroscopy time. PMID:16373264

Gender differences in hip and ankle joint kinematics on knee abduction during running.  

PubMed

The knee is the most common site of running injuries, particularly prevalent in females. The purpose of this study was to clarify gender differences in the lower extremity kinematics during running, with a specific emphasis on the relationships between the distal and proximal factors and the knee joint kinematics. Eleven female and 11 male runners participated in this study. Three-dimensional marker positions were recorded with a motion analysis system while the subjects ran along a 25 m runway at a speed of 3.5 m/s. Kinematic variables were analyzed for the stance phase of the right leg. Female runners demonstrated significantly greater peak knee abduction (P<0.05), hip adduction (P<0.01) and internal rotation (P<0.05), whereas male runners demonstrated significantly greater peak rearfoot eversion (P<0.01). The knee abduction angles were positively correlated with hip adduction angles (r=0.49, P<0.05) and negatively correlated with rearfoot eversion (r= -0.69, P<0.001). There was no significant difference in normalised step width between genders (P>0.05). Smaller rearfoot eversion and greater hip adduction related closely to the greater knee abduction as the distal and proximal factors, respectively. These relationships are thought to be the compensatory joint motions in the frontal plane, because there was no significant difference in the normalised step width between females and males. The current results suggest that if the step width is identical, the subjects with greater knee abduction had smaller rearfoot eversion to compensate for greater hip adduction, which were more apparent in females. This explains greater knee abduction found in female runners, which can be linked to a high risk of knee injury. PMID:24444222

Left Radial Access Is Preferable to Right Radial Access for the Diagnostic or Interventional Coronary Procedures: A Meta-Analysis Involving 22 Randomized Clinical Trials and 10287 Patients  

PubMed Central

Objective The transradial approach has been used extensively for both diagnostic and interventional coronary procedures; however, there is no universal consensus hitherto on the optimal choice of radial access from either the left or the right artery. We therefore sought to meta-analyze available randomized clinical trials to compare the left with the right radial access for the diagnostic or interventional coronary procedures. Methods and Results Four electronic databases including the PubMed, EMBASE, Wanfang, and CNKI were searched up to April 2013. In total, there were 22 qualified randomized trials involving 5317 and 4970 patients assigned to the left and the right radial accesses, respectively. Data were extracted independently by two investigators. Analyses of the full data set indicated significant reductions in fluoroscopy time (seconds) (weighted mean difference; 95% confidence interval; P: ?36.18; ?53.28 to ?18.53; <0.0005) and contrast use (mL) (?2.88; ?5.41 to ?0.34; 0.026) in patients with the left radial access compared to those with the right radial access, and there was strong evidence of heterogeneity but low probability of publication bias. The failure rate of radial access from the left was relatively lower than that from the right (odds ratio: 0.83; 95% confidence interval: 0.68?1.01; P?=?0.064). Further in meta-regression analyses, body mass index was found to be a potential source of heterogeneity for both fluoroscopy time (regression coefficient: 35.85; P?=?0.025) and catheter number (regression coefficient: 0.35; P?=?0.018). Conclusions Our findings demonstrate that left radial access is preferable to right radial access in terms of fluoroscopy time and contrast use for the diagnostic or interventional coronary procedures. The import of this study lies in its great shock to the concept of convenient radial access from the right artery. PMID:24223815

Transfracture abduction osteotomy: A solution for nonunion of femoral neck fractures  

PubMed Central

Background: Nonunion and avascular necrosis (AVN) of the femoral head remains one of the major complications following femoral neck fractures. Despite various surgical techniques and internal fixation devices, the incidence of nonunion and AVN has remained unsolved. Neglected nonunion of femoral neck fracture is common in the developing world. Treatment options include rigid internal fixation with or without bone grafting, muscle pedicle bone graft, valgus osteotomy of the proximal femur with or without bone graft, valgus osteotomy or hip arthroplasty. We conducted a retrospective analysis of cases of nonunion of femoral neck fracture treated by transfracture abduction osteotomy (TFAO). Materials and Methods: Over a period of 35 years (1974-2008), 30 patients with nonunion of femoral neck fractures were treated with TFAO over a period of 35 years (1974-2008), All patients were less than 50 years of age. Absence of clinical and radiological signs of union after four months was considered as nonunion. Patients more than 50 years of age were excluded from the study. Union was assessed at 6 months radiologically. Limb length was measured at six months. The mean duration of femoral neck fracture was 19 months (range 4 months 10 years). Results were analyzed in terms of radiological union at six months. Average followup was five years and six months. Results: Consistent union was noted at the followup after six months in 29 cases. One case was lost to followup after five and one-half months postoperatively. However, the fracture had united in this case at the last followup. Average shortening of the limb at six months was 1.9 cm. Average neck shaft angle was 127° (range 120-145°). Five cases went into AVN but were asymptomatic. Two cases required reoperation due to back out of Moore's pins. These were reopened and cancellous screws were inserted in the same tracks. Conclusions: Consistent union of nonunion femoral neck fracture was noted at the followup after six months in 29 cases. The major drawback of the procedure is immobilization of the patient in the hip spica for eight weeks. PMID:24600059

Effect of acetabular cup abduction angle on wear of ultrahigh-molecular-weight polyethylene in hip simulator testing.  

PubMed

The effect of acetabular component positioning on the wear rates of metal-on-polyethylene articulations has not been extensively studied. Placement of acetabular cups at abduction angles of more than 40° has been noted as a possible reason for early failure caused by increased wear. We conducted a study to evaluate the effects of different acetabular cup abduction angles on polyethylene wear rate, wear area, contact pressure, and contact area. Our in vitro study used a hip joint simulator and finite element analysis to assess the effects of cup orientation at 4 angles (0°, 40°, 50°, 70°) on wear and contact properties. Polyethylene bearings with 28-mm cobalt-chrome femoral heads were cycled in an environment mimicking in vivo joint fluid to determine the volumetric wear rate after 10 million cycles. Contact pressure and contact area for each cup abduction angle were assessed using finite element analysis. Results were correlated with cup abduction angles to determine if there were any differences among the 4 groups. The inverse relationship between volumetric wear rate and acetabular cup inclination angle demonstrated less wear with steeper cup angles. The largest abduction angle (70°) had the lowest contact area, largest contact pressure, and smallest head coverage. Conversely, the smallest abduction angle (0°) had the most wear and most head coverage. Polyethylene wear after total hip arthroplasty is a major cause of osteolysis and aseptic loosening, which may lead to premature implant failure. Several studies have found that high wear rates for cups oriented at steep angles contributed to their failure. Our data demonstrated that larger cup abduction angles were associated with lower, not higher, wear. However, this potentially "protective" effect is likely counteracted by other complications of steep cup angles, including impingement, instability, and edge loading. These factors may be more relevant in explaining why implants fail at a higher rate if cups are oriented at more than 40° of abduction. PMID:25303445

[Purpose] This study investigated the differences in shoulder muscles activities during shoulder abduction between a forward shoulder posture group and asymptomatic group. [Subjects] Seven males with forward shoulder posture (FHS) and seven asymptomatic males were recruited. [Methods] We measured the upper and middle trapezius (UT and MT), serratus anterior (SA), and clavicle portion of the pectoralis major (cPM) in the right side during shoulder abduction. [Results] The activities of the UT and cPM in the FHS group were significantly more increased when compared with the asymptomatic group. The activities of the MT and SA in the FHS group were significantly more decreased when compared with the asymptomatic group. [Conclusion] We suggest that forward shoulder posture may become a potential risk factor evoking the various shoulder disorders. PMID:24259860

Progressive Shoulder Abduction Loading is a Crucial Element of Arm Rehabilitation in Chronic Stroke  

PubMed Central

Background Total reaching range of motion (work area) diminishes as a function of shoulder abduction loading in the paretic arm in individuals with chronic hemiparetic stroke. This occurs when reaching outward against gravity or during transport of an object. Objectives This study implements 2 closely related impairment-based interventions to identify the effect of a subcomponent of reaching exercise thought to be a crucial element in arm rehabilitation. Methods A total of 14 individuals with chronic moderate to severe hemiparesis participated in the participant-blinded, randomized controlled study. The experimental group progressively trained for 8 weeks to actively support the weight of the arm, up to and beyond, while reaching to various outward targets. The control group practiced the same reaching tasks with matched frequency and duration with the weight of the arm supported. Work area and isometric strength were measured before and after the intervention. Results Change scores for work area at 9 loads were calculated for each group. Change scores were significantly larger for the experimental group indicating a larger increase in work area, especially shoulder abduction loads equivalent to those experienced during object transport. Changes in strength were not found within or between groups. Conclusions Progressive shoulder abduction loading can be utilized to ameliorate reaching range of motion against gravity. Future work should investigate the dosage response of this intervention, as well as test whether shoulder abduction loading can augment other therapeutic techniques such as goal-directed functional task practice and behavioral shaping to enhance real-world arm function.

Peak torque (PT), total work (TW) and acceleration time (AT) were measured during isokinetic concentric and eccentric abduction of the shoulder in subjects with subacromial impingement syndrome (SIS) and healthy subjects. The SIS group consisted of 27 subjects (33.48 +/- 9.94 years) with unilateral SIS and it was divided into two groups: (1) SIS with the dominant involved side, (2) SIS with the nondominant involved side. The control group consisted of 23 healthy subjects (32.26 +/- 9.04 years). PT, TW and AT were measured bilaterally at 60 and 180 degrees /s. No significant interactions were found between group and side (P > 0.05), as well as no significant main effects of group and side (P > 0.05) for all variables during concentric abduction of the shoulder at both tested speeds. During the eccentric contractions, lower TW (P < 0.05) was demonstrated by the nondominant uninvolved side of SIS group at 60 degrees /s, and by the uninvolved sides of the SIS groups at 180 degrees /s compared to the dominant side of the controls. At 180 degrees /s, the nondominant uninvolved side of the SIS group demonstrated slower AT (P < 0.05) compared to the dominant side of the control group, as well as the nondominant involved side of the SIS group compared to the nondominant side of the controls. The results showed no alterations in the measured parameters during concentric and eccentric phases of isokinetic abduction in subjects with SIS when compared to a control group. However, alterations may be observed in the contralateral side during the eccentric phase of abduction in subjects with unilateral conditions of SIS. PMID:20131062

Prospective evaluation of the use of Mitchell shoes and dynamic abduction brace for idiopathic clubfeet.  

PubMed

Ponseti treatment for clubfoot has been successful, but recurrence continues to be an issue. After correction, patients are typically braced full time with a static abduction bar and shoes. Patient compliance with bracing is a modifiable risk factor for recurrence. We hypothesized that the use of Mitchell shoes and a dynamic abduction brace would increase compliance and thereby reduce the rate of recurrence. A prospective, randomized trial was carried out with consecutive patients treated for idiopathic clubfeet from 2008 to 2012. After casting and tenotomy, patients were randomized into either the dynamic or static abduction bar group. Both groups used Mitchell shoes. Patient demographics, satisfaction, and compliance were measured with self-reported questionnaires throughout follow-up. Thirty patients were followed up, with 15 in each group. Average follow-up was 18.7 months (range 3-40.7 months). Eight recurrences (26.7%) were found, with four in each group. Recurrences had a statistically significant higher number of casts and a longer follow-up time. Mean income, education level, patient-reported satisfaction and compliance, and age of caregiver tended to be lower in the recurrence group but were not statistically significant. No differences were found between the two brace types. Our study showed excellent patient satisfaction and reported compliance with Mitchell shoes and either the dynamic or static abduction bar. Close attention and careful education should be directed towards patients with known risk factors or difficult casting courses to maximize brace compliance, a modifiable risk factor for recurrence.

Mental Health among Former Child Soldiers and Never-Abducted Children in Northern Uganda  

PubMed Central

The present study aimed to evaluate posttraumatic stress symptoms, psychological distress, and emotional and behavioral problems in former Ugandan child soldiers in comparison with civilian children living in the same conflict setting. Participants included 133 former child soldiers and 101 never-abducted children in northern Uganda, who were interviewed about exposure to traumatic war-related experiences, posttraumatic stress symptoms, psychological distress, and emotional and behavioral problems. Results indicated that former child soldiers had experienced significantly more war-related traumatic events than nonabducted children, with 39.3% of girls having been forced to engage in sexual contact. Total scores on measures of PTSD symptoms, psychological distress, and emotional and behavioral problems were significantly higher among child soldiers compared to their never-abducted peers. Girls reported significantly more emotional and behavioral difficulties than boys. In never-abducted children, more mental health problems were associated with experiencing physical harm, witnessing the killings of other people, and being forced to engage in sexual contact.

Psychophysiological responding during script-driven imagery in people reporting abduction by space aliens.  

PubMed

Is recollection of highly improbable traumatic experiences accompanied by psychophysiological responses indicative of intense emotion? To investigate this issue, we measured heart rate, skin conductance, and left lateral frontalis electromyographic responses in individuals who reported having been abducted by space aliens. Recordings of these participants were made during script-driven imagery of their reported alien encounters and of other stressful, positive, and neutral experiences they reported. We also measured the psychophysiological responses of control participants while they heard the scripts of the abductees. We predicted that if "memories" of alien abduction function like highly stressful memories, then psychophysiological reactivity to the abduction and stressful scripts would be greater than reactivity to the positive and neutral scripts, and this effect would be more pronounced among abductees than among control participants. Contrast analyses confirmed this prediction for all three physiological measures (ps < .05). Therefore, belief that one has been traumatized may generate emotional responses similar to those provoked by recollection of trauma (e.g., combat). PMID:15200635

One-step antibody immobilization-based rapid and highly-sensitive sandwich ELISA procedure for potential in vitro diagnostics  

PubMed Central

An improved enzyme-linked immunosorbent (ELISA) assay using one-step antibody immobilization has been developed for the detection of human fetuin A (HFA), a specific biomarker for atherosclerosis and hepatocellular carcinoma. The anti-HFA formed a stable complex with 3-aminopropyltriethoxysilane (APTES) by ionic and hydrophobic interactions. The complex adsorbed on microtiter plates exhibited a detection range of 4.9?pg mL?1 to 20?ng mL?1 HFA, with a limit of detection of 7?pg mL?1. Furthermore, an analytical sensitivity of 10?pg mL?1 was achieved, representing a 51-fold increase in sensitivity over the commercial sandwich ELISA kit. The results obtained for HFA spiked in diluted human whole blood and plasma showed the same precision as the commercial kit. When stored at 4°C in 0.1?M phosphate-buffered saline (PBS, pH 7.4), the anti-HFA bound microtiter plates displayed no significant decrease in their functional activity after two months. The new ELISA procedure was extended for the detection of C-reactive protein, human albumin and human lipocalin-2 with excellent analytical performance. PMID:24638258

GAVeCeLT* consensus statement on the correct use of totally implantable venous access devices for diagnostic radiology procedures.  

PubMed

The use of totally implantable venous access devices in radiology may be associated with complications such as occlusion of the system (because of the high density of some contrast), infection (if the port is not handled in aseptic conditions, using proper barrier protections), and mechanical complications due to the high-pressure administration of contrast by automatic injectors (so-called power injector), including extravasation of contrast media into the soft tissues, subintimal venous or myocardial injection, or serious damage to the device itself (breakage of the external connections, dislocation of the non-coring needle, or breakage of the catheter). The last problem - i.e., the damage of the device from a power injection - is not an unjustified fear, but a reality. A warning by the US Food and Drug Administration of July 2004 reports around 250 complications of this kind, referring to both port and central venous catheters and peripherally inserted central catheter systems, which occurred over a period of several years; in all cases, the damage occurred during the injection of contrast material by means of power injectors for computed tomography or magnetic resonance imaging procedures. Though the risk associated with the use of ports in radiodiagnostics is thus clear, it has been suggested that administration of the contrast material via the port may have some advantage in terms of image quality, increased comfort for the patient, and maybe more accurate reproducibility of the patient's own follow-up exams. This contention needs to be supported by evidence. Also, since many cancer patients who need frequent computed tomography studies already have totally implantable systems, it would seem reasonable to try to define how and when such systems may safely be used. The purpose of this consensus statement is to define recommendations based on the best available evidence, for the safe use of implantable ports in radiodiagnostics. PMID:21534233

The Effects of Knee Joint and Hip Abduction Angles on the Activation of Cervical and Abdominal Muscles during Bridging Exercises.  

PubMed

[Purpose] The purpose of this study was to examine the effects of the flexion angle of the knee joint and the abduction angle of the hip joint on the activation of the cervical region and abdominal muscles. [Subjects] A total of 42 subjects were enrolled 9 males and 33 females. [Methods] The bridging exercise in this study was one form of exercise with a knee joint flexion angle of 90°. Based on this, a bridging exercise was conducted at the postures of abduction of the lower extremities at 0, 5, 10, and 15°. [Result] The changes in the knee joint angle and the hip abduction angle exhibited statistically significant effects on the cervical erector spinae, adductor magnus, and gluteus medius muscles. The abduction angles did not result in statistically significant effects on the upper trapezium, erector spinae, external oblique, and rectus abdominis muscles. However, in relation to the knee joint angles, during the bridging exercise, statistically significant results were exhibited. [Conclusion] When patients with both cervical and back pain do a bridging exercise, widening the knee joint angle would reduce cervical and shoulder muscle activity through minimal levels of abduction, permitting trunk muscle strengthening with reduced cervical muscle activity. This method would be helpful for strengthening trunk muscles in a selective manner. PMID:24259870

Anterior mediastinal masses: A study of 50 cases by fine needle aspiration cytology and core needle biopsy as a diagnostic procedure  

PubMed Central

Background: Mediastinal tumors are an uncommon abnormalities found in clinical practice. Anterior mediastinum is the common site and tissue diagnoses of anterior mediastinal masses (AMMs) are very important for correct therapeutic decision. Objective: We evaluate the different malignant AMMs in various age groups and the sensitivity of fine needle aspiration cytology (FNAC) and core needle biopsy (CNB). Cytology smears are reviewed with particular emphasis on pitfalls in the cytological diagnosis. Materials and Methods: This was a prospective study of 50 patients who were consulted for AMMs and underwent FNAC and CNB under guidance of ultrasound or computed tomography (CT) scan from 2006 to 2011. Cytology smears and histological sections were evaluated in all patients. Results: Among 50 cases, 36 were male and 14 were female. Most AMMs (52%) were identified in the fifth and sixth decades of life. Metastatic carcinoma and nonHodgkin's lymphoma are the common AMMs. Adequate tissue material was obtained in 49 of 50 cases by CNB. Of these 49 patients, 35 (71.42%) cases were diagnosed correctly by FNAC, whereas 14 (28.57%) cases were not diagnosed definitely by FNAC. The sensitivity of CNB for AMMs was 97.95%, significantly higher than FNAC (71.42%) (P < 0.05). CNB had statistically significant higher diagnostic rate than FNAC in the noncarcinoma group (100% versus 62.96%) (P < 0.05). There is no significant difference of CNB and FNAC in carcinoma group (P > 0.05). Diagnostic rate of FNAC was higher for carcinomatous lesions (81.81%) than for noncarcinomatous lesions (62.96%). Conclusion: Ultrasound or CT scan-guided CNB in combination with FNAC are safe, minimally invasive, and cost-effective procedure, which can provide a precise diagnosis in the AMMs, and may obviate the need for invasive surgical approach. FNAC usually suffice for carcinomatous lesions but CNB should be performed whenever the diagnosis of carcinoma is equivocal or noncarcinoma lesions are suspected. PMID:24455533

CT-guided fine-needle biopsy of focal lung lesions as the method for reducing the number of invasive diagnostic procedures  

PubMed Central

Summary Background: CT-guided fine-needle biopsy (FNB) of focal lung lesions is one of the possibilities of obtaining histopathological diagnosis in pulmonary diseases. Its place in the algorithm is determined by the invasiveness. In case of no diagnosis after bronchoscopy or endobronchial ultrasonography (EBUS) guided biopsy, CT-guided FNB can become an alternative for more invasive procedures, such as open lung biopsy – thoracotomy. Material/Methods: Since January 2009 until February 2010, we performed 37 CT-guided FNB in 34 patients aged 31 to 76 (mean age 60.9). Among them, there were 16 women and 18 men. All patients underwent a standard chest CT with contrast medium injection. They were diagnosed with focal lesions and they were rejected from surgery as the primary method of treatment. During biopsy, the patient was positioned prone or supine, depending on the location of lesions. After performing a scout image and initial slices, we marked the level of biopsy, using a metal marker. Next, the biopsy needle was introduced under local anesthesia. When the obtained position of the needle in the lesion was correct, the specimen was taken. After needle removal, the patient was controlled for the presence of complications (i.e. pneumothorax). Biopsy time ranged from 10 to 50 minutes. Results: In 94.6% of biopsies, the specimens for histopathological and cytological examinations were obtained. In 22 (64.7%) patients, histopathological diagnoses (in 14 cases this was the non-small cell cancer and in 8, inflammatory lesions) were established which allowed us to resign from invasive thoracotomy and to introduce an appropriate treatment. In the remaining 12 patients, no diagnosis was established. Complications in the form of a minor pneumothorax occurred in 2 patients. Conclusions: Fine-needle biopsy of the focal lung lesions is an affective and a relatively safe method, which can replace the more invasive diagnostic thoracotomy in the majority of patients.

Diagnostic imaging.  

PubMed

Physical techniques have always had a key role in medicine, and the second half of the 20th century in particular saw a revolution in medical diagnostic techniques with the development of key imaging instruments: x-ray imaging and emission tomography (nuclear imaging and PET), MRI, and ultrasound. These techniques use the full width of the electromagnetic spectrum, from gamma rays to radio waves, and sound. In most cases, the development of a medical imaging device was opportunistic; many scientists in physics laboratories were experimenting with simple x-ray images within the first year of the discovery of such rays, the development of the cyclotron and later nuclear reactors created the opportunity for nuclear medicine, and one of the co-inventors of MRI was initially attempting to develop an alternative to x-ray diffraction for the analysis of crystal structures. What all these techniques have in common is the brilliant insight of a few pioneering physical scientists and engineers who had the tenacity to develop their inventions, followed by a series of technical innovations that enabled the full diagnostic potential of these instruments to be realised. In this report, we focus on the key part played by these scientists and engineers and the new imaging instruments and diagnostic procedures that they developed. By bringing the key developments and applications together we hope to show the true legacy of physics and engineering in diagnostic medicine. PMID:22516558

Sensitivity of Symptomatology Versus Diagnostic Procedures and Concentration of CEA and CA19-9 in the Early Detection of Colorectal Cancer  

PubMed Central

Introduction: Colorectal cancer is the major diagnostic and therapeutic problem. The number of patients in the world has increased recently. In our country it is detected late and patients visit doctor in the advanced stage of the disease with already developed metastases. Material and methods: A clinical study was conducted at the Clinic of gastroenterohepatologists, Clinical Center of Sarajevo University on 164 patients. Special attention was given to the symptoms, which are considered to be a macroscopically visible as bleeding, anemia pain, weight loss and disturbance of defecation. Smoking had no effect because a small number of observed patients smoked. Endoscopic examination revealed localization of the tumor in the colon and then underwent targeted biopsy, histological analysis by pathologist, and we determined the concentration of CEA and CA19-9 in the serum. Results: In order to get the most relevant results we used larger data set. The program used to prepare the data was Microsoft Excel 2013, and for the creation of decision trees is a used software RapidMiner version 5. Our research has shown that patients older than 55 years with significant stenosis, metastasis and diarrhea that lasted longer than 3.5 months and bleeding that lasted up to 10 months had cancer of the rectum. Bleeding that lasts longer than 10 months indicated that it was the case of cancer that was localized in the rectum in men and sigma in women. Patients older than 82.5 years and had diarrhea up to 3.5 months developed cancer in the sigma part of the colon. Analyzing pain as a symptom of an alarm, the study found that pain that lasts longer than a few days, is caused by rectal cancer, and occurs after the age of 70.5 years, and in patients younger than 63 years anemia as a alarm symptom, which lasted more than two months in men was caused by cancer of the rectum and in women cancer in other localizations within colon. In patients without stenosis developed bleeding as the most important symptom. We can say that after the age of 74 years cancer of the rectum and sigmoid is more common in men and in women dominate sigma and other locations in the colon. In patients under the 70 years of age with short time of bleeding, cancer predominates in rectum. In patients younger than 63 years can be concluded that weight loss is greater than 8 kg follows rectal cancer. In patients with bleeding that lasted one month or more as classifier occurring the age and gender. Patients younger than 74 years have rectal cancer, while older than 73 years have cancer at other sites. In women these locations are sigma and rectum. Conclusion: Based on this study we can conclude that regardless of the technical advances in medicine must pay special attention to the symptoms that doctors will refer to the localization of the tumor, stenosis of the intestine and possibly metastasis. Key words: Colorectal cancer, diagnostic procedures, concentration of CEA and CA19-9. PMID:24825931

In vivo 3D analysis of clavicular kinematics during scapular plane abduction: comparison of dominant and non-dominant shoulders.  

PubMed

The purpose of this study was to evaluate side-to-side differences in three-dimensional clavicle kinematics in normal shoulders during dynamic scapular plane elevation using model-image registration techniques. Twelve healthy males with a mean age of 32 years (range, 27-36 years old) were enrolled in this study. Clavicle rotations were computed with bilateral fluoroscopic images and CT-derived bone models using model-image registration techniques and compared between dominant and nondominant shoulders. There was no difference in retraction between both shoulders. The clavicle in dominant shoulders was less elevated during abduction than in nondominant shoulders (P=0.03). Backward rotation angles of dominant shoulders were significantly smaller than those of nondominant shoulders throughout the activity (P=0.03). Clavicular kinematics during scapular plane abduction were different according to hand-dominance. PMID:23871318

Utility of combined hip abduction angle for hip surveillance in children with cerebral palsy  

PubMed Central

Background: Spontaneous hip lateralization complicates the management of non-ambulatory children with cerebral palsy (CP). It can be diagnosed early using radiographs, but it involves standardization of positioning and exposure to radiation. Hence, the aim of this study was to assess the utility of Combined hip abduction angle (CHAA) in the clinical setting to identify those children with CP who were at greater risk to develop spontaneous progressive hip lateralization. Materials and Methods: One hundred and three children (206 hips) with CP formed our study population. There were 48 boys and 55 girls aged 2–11 years (mean 5.03 years). 61 children were Gross Motor Function Classification System (GMFCS) level 5, while 42 were GMFCS level 4. Clinical measurements of CHAA were statistically correlated with radiographic measurements of Reimer's migration percentage (MP) for bivariate associations using ?2 and t tests. Results: CHAA is evaluated against MP which is considered as a reliable measure of hip subluxation. Thus, for CHAA, sensitivity was 74.07% and specificity was 67.35%. False-positive rate was 32.65% and false-negative rate was 25.93%. Conclusions: Our study shows that correlation exists between CHAA and MP, which has been proved to be useful for hip screening in CP children at risk of hip dislocation. CHAA is an easy, rapid, cost-effective clinical test which can be performed by paraclinical health practitioners (physiotherapists) and orthopedic surgeons. PMID:22144749

In vivo gleno-humeral joint loads during forward flexion and abduction.  

PubMed

To improve design and preclinical test scenarios of shoulder joint implants as well as computer-based musculoskeletal models, a precise knowledge of realistic loads acting in vivo is necessary. Such data are also helpful to optimize physiotherapy after joint replacement and fractures. This is the first study that presents forces and moments measured in vivo in the gleno-humeral joint of 6 patients during forward flexion and abduction of the straight arm. The peak forces and, even more, the maximum moments varied inter-individually to a considerable extent. Forces of up to 238%BW (percent of body weight) and moments up to 1.74%BWm were determined. For elevation angles of less than 90° the forces agreed with many previous model-based calculations. At higher elevation angles, however, the measured loads still rose in contrast to the analytical results. When the exercises were performed at a higher speed, the peak forces decreased. The force directions relative to the humerus remained quite constant throughout the whole motion. Large moments in the joint indicate that friction in shoulder implants is high if the glenoid is not replaced. A friction coefficient of 0.1-0.2 seems to be realistic in these cases. PMID:21481879

Comparison of Isokinetic Hip Abduction and Adduction Peak Torques and Ratio Between Sexes  

PubMed Central

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

Frequency of use of diagnostic and manual therapeutic procedures of the spine taught at the Canadian Memorial Chiropractic College: A preliminary survey of Ontario chiropractors. Part 1 - practice characteristics and demographic profiles  

PubMed Central

Background: Students learn a plethora of physical examination and manual therapy procedures over the course of their chiropractic education. However, it is uncertain to what extent they continue to use these procedures in practice after graduation. Objective: The purpose of this study was to determine which diagnostic and therapeutic procedures of the spine are most commonly utilized by chiropractors practicing in Ontario. In Part 1 of this study (presented here), the demographics and practice patterns of the respondents are presented. Part 2 of this study will present the results of the utilization rates of diagnostic and therapeutic procedures used by respondents. Methods: The study consisted of a paper-based survey that was sent to 500 pseudo-randomly selected Ontario chiropractors who responded confidentially. Survey questions inquired into demographic and practice style characteristics. Results: There were 108 respondents to the survey, giving a response rate of 22.4%. Many chiropractors self-identified themselves with more than one practice style characteristic such as 72.4% of the self-described pain-based chiropractors who also described themselves as evidence-based, compared with 51.9% of subluxation-based chiropractors who also described themselves as evidence-based. Diversified technique was the most commonly employed technique used by 90.7% of respondents, followed by trigger point therapy indicated by 57.4% of respondents. Conclusions: Despite a low response rate, respondents reported practice characteristics in this study that were similar to practice characteristics previously published, particularly in terms of professional demographics and techniques employed. While Diversified was the most commonly used technique, respondents reported higher levels of use of proprietary soft tissue techniques systems and upper cervical techniques than have been previously reported.

Patient satisfaction and quality of care at four diagnostic imaging procedures: mammography, double-contrast barium enema, abdominal ultrasonography and vaginal ultrasonography.  

PubMed

The objective of this study was to measure patient satisfaction and to investigate the practical implications of monitoring the quality of care at four radiology procedures. A survey was conducted immediately after the examinations in eight radiology departments: 550 patients attending for mammography, 110 for double-contrast barium enema (DCBE), 97 for abdominal ultrasonography and 90 for vaginal ultrasonography. Outcome measures were seven questionnaire scales: pain, emotional distress, information received, staff's punctuality and technical ability, facilities, and general satisfaction. Response rate was 87 %. Multivariate regression analysis showed significant differences between procedures on all scales (p < 0.001). Differences considered to be of practical importance, i. e. >/= 7 scale points, were detected on five of the scales. Mammography and DCBE caused the most pain, and vaginal US and DCBE caused the most distress. The US procedures entailed dissatisfaction with information about the procedures. The DCBE patients recorded dissatisfaction with the staff's lack of punctuality, and these and the mammography patients recorded dissatisfaction with the facilities. The findings indicate a potential for improving patients' experiences. Several aspects of care, i. e. pain management, attention to the patient's emotional concerns, explanation of procedures, punctuality and quality of the facilities, can be improved. PMID:10460397

The influence of age on isometric endurance and fatigue is muscle dependent: a study of shoulder abduction and torso extension.  

PubMed

The present study examined differences in isometric muscle capacity between older (55-65 years) and younger (18 - 25 years) individuals. A total of 24 younger and 24 older participants (gender balanced within each group) performed sustained shoulder abductions and torso extensions to exhaustion at 30%, 50% and 70% of individual maximal voluntary contraction (MVC). Along with endurance time, manifestations of localized fatigue were determined based on changes in surface electromyographic signals obtained from the shoulder (middle deltoid) and the torso (multifidus and longissimus thoracis) muscles. Strength recovery was monitored using post-fatigue MVCs over a 15-min period. Compared to the younger group, older individuals exhibited lower muscular strength, longer endurance time and slower development of local fatigue. Age effects on fatigue were typically moderated by effort level, while effects of gender appeared to be marginal. Non-linear relationships between target joint torque and endurance time were observed, with effects of age differing between shoulder abduction and torso extension. Overall, the effects of age on endurance and fatigue were more substantial and more consistent for the shoulder muscle than for the torso muscles and were likely related to differences in muscle fibre type composition. For strength recovery rates, no significant age or gender effects were found in either experiment. In summary, this study suggests that differences in isometric work capacity do exist between older and younger individuals, but that this effect is influenced by effort level and the muscle tested.

Attendance at Cervical Cancer Screening and Use of Diagnostic and Therapeutic Procedures on the Uterine Cervix Assessed from Individual Health Insurance Data (Belgium, 2002-2006)  

PubMed Central

Objective To assess the coverage for cervical cancer screening as well as the use of cervical cytology, colposcopy and other diagnostic and therapeutic interventions on the uterine cervix in Belgium, using individual health insurance data. Methods The Intermutualistic Agency compiled a database containing 14 million records from reimbursement claims for Pap smears, colposcopies, cervical biopsies and surgery, performed between 2002 and 2006. Cervical cancer screening coverage was defined as the proportion of women aged 25–64 that had a Pap smear within the last 3 years. Results Cervical cancer screening coverage was 61% at national level, for the target population of women between 25 and 64 years old, in the period 2004–2006. Differences between the 3 regions were small, but varied more substantially between provinces. Coverage was 70% for 25–34 year old women, 67% for those aged 35–39 years, and decreased to 44% in the age group of 60–64 years. The median screening interval was 13 months. The screening coverage varied substantially by social category: 40% and 64%, in women categorised as beneficiary or not-beneficiary of increased reimbursement from social insurance, respectively. In the 3-year period 2004–2006, 3.2 million screen tests were done in the target group consisting of 2.8 million women. However, only 1.7 million women got one or more smears and 1.1 million women had no smears, corresponding to an average of 1.88 smears per woman in three years of time. Colposcopy was excessively used (number of Pap smears over colposcopies?=?3.2). The proportion of women with a history of conisation or hysterectomy, before the age of 65, was 7% and 19%, respectively. Conclusion The screening coverage increased slightly from 59% in 2000 to 61% in 2006. The screening intensity remained at a high level, and the number of cytological examinations was theoretically sufficient to cover more than the whole target population. PMID:24690620

Modified Woodward procedure for Sprengel deformity of the shoulder: long-term results.  

PubMed

Sprengel deformity of the shoulder is characterized by elevation and medial rotation of the inferior pole of the scapula. Surgical treatment is recommended in significantly involved patients to improve cosmetic appearance and function of the involved shoulder. We report long-term results of a Woodward procedure modified by excision of the prominent superomedial border of the scapula for correction of this deformity in 15 patients. Preoperatively, the total abduction of the shoulder averaged 115 degrees, and on follow-up the abduction had improved to an average of 150 degrees. In all patients except one, there was marked improvement in appearance as assessed on Cavendish scale. All patients except two had achieved skeletal maturity at the last follow-up. Eighty-six percent of patients expressed satisfaction with operative results. Our data support the concept that correction achieved by a modified Woodward procedure is not altered by growth and is maintained beyond skeletal maturity. PMID:8784708

The effect of geometry and abduction angle on the stresses in cemented UHMWPE acetabular cups - finite element simulations and experimental tests  

PubMed Central

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

Pneumothorax after diagnostic laparoscopy.  

PubMed

Here we want to call laparoscopist's attention to pneumothorax after diagnostic laparoscopy. Diagnostic laparoscopy has less complications, compared with laparoscopic surgery. In our experience, only one case (0.04%) developed pneumothorax during routine diagnostic laparoscopic procedure. This complication is presented in a 50-year-old female. She complained of dyspnea just after the decrease of intraabdominal pressure and deflation of intraperitoneal gas. The chest roentgenogram showed a right pneumothorax, and a right chest tube was inserted with immediate relief of tension. Pneumothorax during diagnostic laparoscopy is relatively rare but a major complication; Medline literature research showed six reported cases of pneumothorax after diagnostic laparoscopy from 1983 to 1998 including our case. The etiology was idiopathy in 5 and diaphragmatic injury in 1. Hypotension, elevation of inspiratory pressure, dyspnea, a decrease in systemic oxygen saturation, and loss of breath sounds suggest tension pneumothorax. The clinical condition of the patients improved rapidly because of the easy diffusion of the gas used in laparoscopy. Diagnostic laparoscopists should be aware of this complication and treat ventilatory problems. PMID:12143195

[Efficient and rational laboratory diagnostics in otolaryngology].  

PubMed

This article describes the value of laboratory diagnostic procedures in the diagnostic arsenal of otolaryngologists. The rational and therefore the rationale of the application of laboratory medical methods are critically evaluated. In the era of diagnosis-related groups a high value is placed on a rational laboratory diagnostic, in the sense of a cost-oriented medicine, so that the laboratory diagnostic procedure is always carried out in stages, just as in other diagnostic procedures. The possibilities of clinical chemistry, separated into the theme blocks "clinical chemical basic diagnostics", "haematological parameters", "coagulation investigations" and "immunological diagnostics" are demonstrated based on examples. These are aimed at the needs of otolaryngologists, in that the emphasis in each theme block is centred on the indications and evaluation of the individual laboratory investigation. PMID:18704349

A series of 98 patients with spontaneous nipple discharge, is reported. Diagnosis was based on: clinical examination, cytology of breast secretion, mammography and galactography. Surgical resection was recommended in the following cases: galactographic evidence of intraductal papilloma or papillomatosis, dubious or positive cytology, persisting hemorrhagic or sero-hemorrhagic secretion. The injection of vital staining before the operation allowed the precise location of the lesion. In the group of patients studied ten cases of ductal carcinomas (5 in situ and 5 smaller than 1 cm), 4 cases of atypical intraductal hyperplasia, 13 cases of solitary papilloma and 22 cases of multiple papillomatosis were diagnosed.

In general, hemospermia represents a trivial condition: nevertheless, it is often alarming for the patient and his partner. Although differential diagnosis is comprehensive, the most frequent underlying causes are infection and inflammatory processes in the lower seminal passages. Cases of primary and solitary hemospermia can be adequately assessed by urinalysis, blood pressure measurement, and reassurance of the patient. Persistent and recurrent cases of hemospermia are best clarified by transrectal ultrasound examination, cystoscopy, and magnetic resonance imaging. Treatment is based on the examination results.

Impairment-Based 3-D Robotic Intervention Improves Upper Extremity Work Area in Chronic Stroke: Targeting Abnormal Joint Torque Coupling With Progressive Shoulder Abduction Loading  

PubMed Central

The implementation of a robotic system (ACT3D) that allowed for a quantitative measurement of abnormal joint torque coupling in chronic stroke survivors and, most importantly, a quantitative means of initiating and progressing an impairment-based intervention, is described. Individuals with chronic moderate to severe stroke (n = 8) participated in this single-group pretest-posttest design study. Subjects were trained over eight weeks by progressively increasing the level of shoulder abduction loading experienced by the participant during reaching repetitions as performance improved. Reaching work area was evaluated pre- and postintervention for ten different shoulder abduction loading levels along with isometric single-joint strength and a qualitative clinical assessment of impairment. There was a significant effect of session (pre versus post) with an increase in reaching work area, despite no change in single-joint strength. This data suggests that specifically targeting the abnormal joint torque coupling impairment through progressive shoulder abduction loading is an effective strategy for improving reaching work area following hemiparetic stroke. Application of robotics, namely, the ACT3D, allowed for quantitative control of the exercise parameters needed to directly target the synergistic coupling impairment. The targeted reduction of abnormal joint torque coupling is likely the key factor explaining the improvements in reaching range of motion achieved with this intervention. PMID:20657711

Diagnostic imaging in pediatric emergencies  

SciTech Connect

Evaluation of pediatric emergencies by diagnostic imaging technics can involve both invasive and noninvasive procedures. Nuclear medicine, conventional radiography, ultrasound, computerized axial tomography, and xeroradiography are the major nonangiographic diagnostic technics available for patient evaluation. We will emphasize the use of computerized axial tomography, nuclear medicine, xeroradiography, and ultrasound in the evaluation of emergencies in the pediatric age group. Since the radiologist is the primary consultant with regard to diagnostic imaging, his knowledge of these modulities can greatly influence patient care and clinical results.

The application of immunologic techniques to tissue sections has added a new dimension to the investigation and classification of various processes. Virtually every section of diagnostic pathology has been enhanced by using specific monoclonal antibodies or polyclonal antiserum. Neoplasms formerly diagnosed as poorly differentiated or anaplastic may be precisely identified as to their origin through the use of specific membrane or cytoplasmic markers. Other cellular products, including viruses, hormones, enzymes or highly specific proteins, are also available to study neoplastic and nonneoplastic processes. New and more specific reagents are regularly becoming available for the diagnostic repertoire of pathologists. We present some of the principles of diagnostic immunopathology to show the scope and importance of the techniques. ImagesFigure 2.Figure 3. PMID:3529633

Cotton-based Diagnostic Devices.  

PubMed

A good diagnostic procedure avoids wasting medical resources, is easy to use, resists contamination, and provides accurate information quickly to allow for rapid follow-up therapies. We developed a novel diagnostic procedure using a "cotton-based diagnostic device" capable of real-time detection, i.e., in vitro diagnostics (IVD), which avoids reagent contamination problems common to existing biomedical devices and achieves the abovementioned goals of economy, efficiency, ease of use, and speed. Our research reinforces the advantages of an easy-to-use, highly accurate diagnostic device created from an inexpensive and readily available U.S. FDA-approved material (i.e., cotton as flow channel and chromatography paper as reaction zone) that adopts a standard calibration curve method in a buffer system (i.e., nitrite, BSA, urobilinogen and uric acid assays) to accurately obtain semi-quantitative information and limit the cross-contamination common to multiple-use tools. Our system, which specifically targets urinalysis diagnostics and employs a multiple biomarker approach, requires no electricity, no professional training, and is exceptionally portable for use in remote or home settings. This could be particularly useful in less industrialized areas. PMID:25393975

Diagnostic immunofluorescence*  

PubMed Central

The standardization of diagnostic immunofluorescence is a complex problem because diagnostic results are greatly influenced by interacting factors, such as the equipment, materials, and techniques for expressing and recording fluorescence. Furthermore, the characteristics of immunofluorescence reagents depend on how they are manufactured and used. The adoption of stable reference preparations of such reagents appears to be the only practicable way of standardizing laboratory test results. Several professional and regulatory organizations are actively promoting this objective. Consensus evaluation may be the best method of introducing proposed standards. Basic and applied research must provide the information needed to improve reagents and tests. Material fluorescent standards are proving helpful in standardizing fluorescence emission, but the most promising development is the use of insolubilized antigens to provide standards for more relevant immunological-fluorescence comparisons. Several important direct and indirect diagnostic immunofluorescence tests and reagents currently used in microbiological, histological, and pathological examinations require standardization. The medical profession should insist that commercial reagents be adequately characterized and that manufacturers supply the data necessary for their safe and informed use. PMID:4594319

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.

Different hip rotations influence hip abductor muscles activity during isometric side-lying hip abduction in subjects with gluteus medius weakness.  

PubMed

The purpose of this study was to establish the effects of different hip rotations during isometric side-lying hip abduction (SHA) in subjects with gluteus medius (Gmed) weakness by investigating the electromyographic (EMG) amplitude of the Gmed, tensor fasciae latae (TFL) activity, and gluteus maximus (Gmax), and the activity ratio of the Gmed/TFL, Gmax/TFL, and Gmed/Gmax. Nineteen subjects with Gmed weakness were recruited for this study. Subjects performed three isometric hip abductions: frontal SHA with neutral hips (SHA-N), frontal SHA with hip medial rotation (SHA-MR), and frontal SHA with hip lateral rotation (SHA-LR). Surface EMG amplitude was measured to collect the EMG data from the Gmed, TFL, and Gmax. A one-way repeated-measures analysis of variance was used to determine the statistical significance of the Gmed, TFL, and Gmax EMG activity and the Gmed/TFL, Gmax/TFL, and Gmed/Gmax EMG activity ratios. Gmed EMG activity was significantly greater in SHA-MR than in SHA-N. TFL EMG activity was significantly greater in SHA-LR than in SHA-N. The Gmed/TFL and Gmed/Gmax EMG activity ratios were also significantly greater in SHA-MR than in SHA-N or SHA-LR. The results of this study suggest that SHA-MR can be used as an effective method to increase Gmed activation and to decrease TFL activity during SHA exercises. PMID:24560168

Outcome of Mears procedure for Sprengel's deformity  

PubMed Central

Background: Sprengel’s shoulder is characterized by scapular maldescent and malposition, causing restriction of shoulder and cervical spine movements. It is associated with a variety of other congenital anomalies. Various surgical procedures have been described to treat this anomaly with no consensus as to the surgical procedure of choice. We report the results of the Mears procedure in the treatment of Sprengel’s shoulder. Materials and Methods: Seven children between the age group of two and six years were treated for Sprengel’s deformity, with omovertebral bar, and other congenital anomalies. The Cavendish score and Rigault radiological score were used to assess the severity of the deformity, and the position of the scapula relative to the cervical spine, respectively. The Mears procedure involved scapular osteotomy, par tial scapular excision, and release of a long head of triceps. Clavicular osteotomy was done only in two cases to decrease the risk of traction injury to the brachial plexus. Postoperatively, the patients were immobilized in a shoulder sling and range of motion exercises were started as early as possible. The patients were followed regularly at six weeks, three months and regularly at six-months interval. Results: The mean improvement in flexion and abduction was 45 ° (40 – 70 °) and 50 ° (40 – 70 °), respectively, which was the combined glenohumeral and thoracoscapular movement. The cosmetic and functional improvement by this procedure was acceptable to the patients. Minor scar hypertrophy was seen in two cases. Conclusion: The Mears procedure gives excellent cosmetic and functional results. This procedure addresses the functional aspect of the deformity and is much more acceptable to the patient and parents. PMID:21430867

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.

Intensity of amnesia during hypnosis is positively correlated with estimated prevalence of sexual abuse and alien abductions: implications for the false memory syndrome.

20 normal young women listened to an ambiguous story concerning a young boy who experienced fear, odd smells, and a smothering sensation during the night and skin lesions the next morning. After the Hypnotic Induction Profile (HIP) had been established, they were asked to estimate either the percentage prevalence of childhood sexual abuse or alien abduction in the general population. There were moderate (0.50) positive correlations between the subjects' estimates of prevalence and the amount of amnesia ("lost time") and indices of right-hemispheric anomalies (history of sensed presence and left-ear suppressions during a dichotic-listening task). Relevance of observations to formation of the False Memory Syndrome and to the development of nonpsychotic delusions is discussed. PMID:8284172

Neuropsychological profiles of adults who report "sudden remembering" of early childhood memories: implications for claims of sex abuse and alien visitation/abduction experiences.  

PubMed

Six adults, who had recently experienced sudden recall of preschool memories of sex abuse or alien abduction/visitation, were given complete neuropsychological assessments. All experiences "emerged" when hypnosis was utilized within a context of sex abuse or New Age religion and were followed by reduction in anxiety. As a group, these subjects displayed significant (T greater than 70) elevations of childhood imaginings, complex partial epileptic-like signs, and suggestibility. Neuropsychological data indicated right frontotemporal anomalies and reduced access to the right parietal lobe. MMPI profiles were normal. The results support the hypothesis that enhanced imagery due to temporal lobe lability within specific contexts can facilitate the creation of memories; they are strengthened further if there is also reduction in anxiety.

Effect of time pressure on attentional shift and anticipatory postural control during unilateral shoulder abduction reactions in an oddball-like paradigm  

PubMed Central

Background The effect of time pressure on attentional shift and anticipatory postural control was investigated during unilateral shoulder abduction reactions in an oddball-like paradigm. Methods A cue signal (S1) - imperative signal (S2) sequence was repeated with various S2-S1 intervals (1.0, 1.5, and 2.0 s). S2 comprised target and non-target stimuli presented at the position (9° to the left or the right) indicated by S1. Right shoulder abduction was performed only in response to target stimuli, which were presented with a 30% probability. The P1, N1, N2, and P3 components of event-related potentials were analyzed, and onset times of postural muscles (electromyographic activity of erector spinae and gluteus medius) were quantified with respect to middle deltoid activation. Results There was no significant effect of S2-S1 interval on the latency or amplitude of P1, N1, or N2. The percentage of subjects with bimodal P3 peaks was significantly smaller and the slope of the P3 waveform in the 100 ms after the first peak was significantly steeper with a 1.0-s S2-S1 interval than with a 1.5- or 2.0-s S2-S1 interval. The onset of postural muscle activity was significantly later in the shorter interval conditions. Conclusions These results suggest that with a shorter S2-S1 interval, that is, higher time pressure, attention was allocated to hasten the latter part of cognitive processing that may relate to attentional shift from S2 to next S1, which led to insufficient postural preparation associated with arm movement and anticipatory attention directed to S2.

Musculoskeletal Aspiration Procedures  

PubMed Central

With advances in imaging technology, there has been a significant increase in the number and range of interventional musculoskeletal image-guided procedures. One of the most commonly performed image-guided musculoskeletal interventions is the diagnostic and therapeutic percutaneous aspiration and drainage of multiple types of intra-articular, juxta-articular, and intramuscular pathologic fluid collections. These procedures may be performed under fluoroscopic, ultrasound, computed tomography, or even magnetic resonance guidance depending on the location to be accessed, type of pathology, patient characteristics, and operator preference. Musculoskeletal image-guided aspiration and drainage procedures are minimally invasive and generally very safe while offering valuable diagnostic information as well as therapeutic benefit. This article focuses on the appropriate indications, contraindications, and general technique for accessing the major joints via imaging guidance. For each joint, we discuss pertinent anatomy, appropriate imaging modalities, and preferred approaches to gaining intra-articular access. Additionally, the article discusses some of the more frequently encountered juxta-articular and intramuscular fluid collections that can be accessed and aspirated via percutaneous intervention, with mention of the importance of recognizing extremity sarcomas that can mimic these benign collections.

Optical Diagnostics in Medicine  

NASA Astrophysics Data System (ADS)

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.

Evaluating a Dental Diagnostic Terminology in an Electronic Health Record  

PubMed Central

Standardized treatment procedure codes and terms are routinely used in dentistry. Utilization of a diagnostic terminology is common in medicine, but there is not a satisfactory or commonly standardized dental diagnostic terminology available at this time. Recent advances in dental informatics have provided an opportunity for inclusion of diagnostic codes and terms as part of treatment planning and documentation in the patient treatment history. This article reports the results of the use of a diagnostic coding system in a large dental school’s predoctoral clinical practice. A list of diagnostic codes and terms, called Z codes, was developed by dental faculty members. The diagnostic codes and terms were implemented into an electronic health record (EHR) for use in a predoctoral dental clinic. The utilization of diagnostic terms was quantified. The validity of Z code entry was evaluated by comparing the diagnostic term entered to the procedure performed, where valid diagnosis-procedure associations were determined by consensus among three calibrated academically based dentists. A total of 115,004 dental procedures were entered into the EHR during the year sampled. Of those, 43,053 were excluded from this analysis because they represent diagnosis or other procedures unrelated to treatments. Among the 71,951 treatment procedures, 27,973 had diagnoses assigned to them with an overall utilization of 38.9 percent. Of the 147 available Z codes, ninety-three were used (63.3 percent). There were 335 unique procedures provided and 2,127 procedure/diagnosis pairs captured in the EHR. Overall, 76.7 percent of the diagnoses entered were valid. We conclude that dental diagnostic terminology can be incorporated within an electronic health record and utilized in an academic clinical environment. Challenges remain in the development of terms and implementation and ease of use that, if resolved, would improve the utilization. PMID:21546594

The effect of botulinum toxin type A and a variable hip abduction orthosis on gross motor function: a randomized controlled trial.  

PubMed

Hip displacement is the second most common deformity after equinus in children with cerebral palsy (CP), and may result in dislocation, pain, fixed deformity and loss of function. We studied the combined effects of intramuscular injections of botulinum toxin type A (BTX-A) to the adductors and hamstrings and a variable hip abduction orthosis (SWASH), on gross motor function, hip displacement and progression to surgery, in a randomized clinical trial. Thirty-nine children, with bilateral spastic cerebral palsy, and mean age 3 years + 2 months (range 1 year+7 months--4 years +10 months) entered the trial. Gross Motor Function Classification System (GMFCS) levels were as follows: one child was level II, 11 were level III, 13 were level IV and 14 were level V. After concealed randomization, 20 were allocated to the control group and 19 to the intervention group. Thirty-five children completed the follow up at 1 year. The novel intervention group received up to 4.0 U BOTOX/kg/muscle, 16 U/kg/body weight every 6 months plus the use of a SWASH brace. The control group received clinical best practice comprising physiotherapy but no hip abduction bracing. Both groups showed improvements in total Gross Motor Function Measure (GMFM) score [mean 6.0% BTX-A group; 6.1% Control; 95% CI -- 6.7, 6.5 (NS)], however, there was no additional treatment effect for the study group. There were similar improvements on GMFM goal scores and GMFM-66 scores, but again no additional treatment effect was observed. Multiple regression of change in total GMFM by GMFCS classification for each group showed greater improvement in the total scores from baseline in the BTX-A/SWASH treated group than the control group. In the first year, nine children (two in the intervention group and seven in the control group) required soft tissue surgery because of progressive hip migration in excess of 40%. A longer-term follow up of a larger cohort may be required to determine the effect of the combined treatment on hip displacement. PMID:11851739

A case study of the abductive reasoning processes of pre-service elementary education students in a role playing setting concerning a mock senate hearing on global climate change  

NASA Astrophysics Data System (ADS)

Science education has a rich history of studies into the impact of analogical reasoning upon researcher and student alike. These have focused on how induction and deduction are utilized in determining the appropriateness of the analogy being scrutinized. Research in artificial intelligence has demonstrated that human cognition cannot be modeled with only inductive and deductive forms of logic. Charles S. Peirce proposed abduction as a form of logic central to the process of inquiry and discovery. This involves reasoning from observation to best explanation or hypothesis. Peirce's Theory of Signs provided the theoretical foundation and a model of abduction developed by Shank and Cunningham from Peirce's theory offered the conceptual basis for the study. This study uses discourse analysis to attempt to understand the abductive reasoning processes of two groups of students as they interpret new information concerning the political and scientific perspective of the Greening Earth Society and the Center for Disease Control in an authentic, undergraduate-level classroom setting. The five students were members of a capstone course in science education for pre-service elementary education majors who had an interest in science education. The entire class was comprised of fourteen students partitioned into five groups for the culminating exercise for the course. Analysis was carried out using journal entries, audiotapes of planning sessions, a brief summary of their understanding, and videotapes of the mock Senate hearings. The results demonstrated that different members of the group arrived at their understanding using different pathways suggested by the model. While some proceeded linearly, others skipped some stages and later came back to find supportive evidence to strengthen their beliefs. The model is useful in understanding their abductive processes and may provide insight into how we might consider the process in the design of future curriculum for elementary science education.

BEAM SIMULATIONS USING VIRTUAL DIAGNOSTICS FOR THE DRIVER LINAC  

SciTech Connect

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.

Peritonectomy procedures.  

PubMed Central

OBJECTIVE: New surgical procedures designed to assist in the treatment of peritoneal surface malignancy were sought. BACKGROUND: Decisions regarding the treatment of cancer depend on the anatomic location of the malignancy and the biologic aggressiveness of the disease. Some patients may have isolated intra-abdominal seeding of malignancy of limited extent or of low biologic grade. In the past, these clinical situations have been regarded as lethal. METHODS: The cytoreductive approach may require six peritonectomy procedures to resect or strip cancer from all intra-abdominal surfaces. RESULTS: These are greater omentectomy-splenectomy; left upper quadrant peritonectomy; right upper quadrant peritonectomy; lesser omentectomy-cholecystectomy with stripping of the omental bursa; pelvic peritonectomy with sleeve resection of the sigmoid colon; and antrectomy. CONCLUSIONS: Peritonectomy procedures and preparation of the abdomen for early postoperative intraperitoneal chemotherapy were described. The author has used the cytoreductive approach to achieve long-term, disease-free survival in selected patients with peritoneal carcinomatosis, peritoneal sarcomatosis or mesothelioma.

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

Maintenance of arytenoid abduction following carbon dioxide laser debridement of the articular cartilage and joint capsule of the cricoarytenoid joint combined with prosthetic laryngoplasty in horses: an in vivo and in vitro study.  

PubMed

The objective was to evaluate CO2 laser debridement of the cricoarytenoid joint (CAJ) combined with prosthetic laryngoplasty to prevent post-operative loss of arytenoid abduction in seven horses. Horses were assigned to either laser debridement of the left CAJ and laryngoplasty (laser treated, n=5) or control laryngoplasty (sham, n=2), and were evaluated with endoscopic examinations and measurement of right to left angle quotients (RLQ) to assess maintenance of arytenoid abduction. The animals were euthanased at intervals after surgery and larynges were harvested for post-mortem testing, including determination of translaryngeal flow, pressure, impedance and RLQ. Measurements were obtained under increasing vacuum-generated negative pressure with laryngoplasty sutures intact and with the knot/crimp of the laryngoplasty sutures removed. Following post-mortem testing the cricoarytenoid joints were examined histologically. Post-operative endoscopic examinations revealed no significant differences between RLQ measurements calculated for day 1 following surgery to the termination date of the study for the seven horses. Post-mortem RLQ at airflows of 10 and 60 L/s was significantly higher in sham than in laser treated horses both before and after knot/crimp removal. Translaryngeal impedance at 10 and 60 L/s was not statistically different between groups. Histopathology revealed necrosis and loss of articular cartilage in the laser treated horses. The lymphoid cell infiltration subsided but joint capsule and periarticular fibrosis increased over the course of the study. Post-operative loss of arytenoid abduction after laryngoplasty can be minimized with CO2 laser debridement of the CAJ joint. PMID:24405681

Cable Diagnostic Focused Initiative  

SciTech Connect

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.

Vocal cord granulomas are benign inflammatory lesions of the vocal cords. They are usually located over the vocal process of the arytenoid cartilage. A corresponding ulcer on the contralateral side is a common finding. Clinical signs include foreign body sensation, a need to repeatedly clear one's throat, hoarseness, and reduced voice resilience. Voice abuse and gastro-oesophageal reflux are commonly cited important aetiological factors. Differentiation from malignant lesions is usually possible by history and clinical examination; biopsy is only rarely necessary. The primary treatment is speech therapy or voice counselling, if necessary, supported by antacids. Surgical excision is not helpful because contact granulomas tend to recur. We present two typical cases of vocal cord granulomas and discuss their management. PMID:19183917

Neutron Diagnostics for NIF  

NASA Astrophysics Data System (ADS)

The National Ignition Facility (NIF) will be a pre-emminent facility for research on burning plasmas. Los Alamos National Laboratory is developing a focus area of coordinating fusion reaction product diagnostics on NIF and studying fusion burn. We will be developing ``core'' diagnostics for NIF including neutron time-of-flight and single-hit systems for ion temperature and neutron spectra, measurements of ``bang-time'' (time of fusion burn relative to start of laser pulse), and support for activation measurements for high-yield and radiochemical analysis.

Diagnostic approach to cerebral aneurysms.  

PubMed

Cerebral aneurysms are an important cause of morbidity and mortality due to their causal effect in non-traumatic subarachnoid hemorrhage. Neurosurgical progress in the 20th century helped to improve patient outcomes greatly. In recent years, techniques such as intravascular treatment by coiling and/or stenting have found an additional place in the management of the disease. With the development of less and less invasive surgical and endovascular techniques, there has also been a continuous development in imaging techniques that have led to our current situation where we dispose of CT and MR techniques that can help improve treatment planning greatly. CT is able to detect and together with its adjunct techniques CT angiography and CT perfusion, it can allow us to provide the physicians in charge with a detailed image of the aneurysm, the feeding vessels as well as the status of blood flow to the brain. Angiography has evolved by becoming the standard tool for guidance during decision making for whatever therapy is being envisioned be it endovascular procedures and or surgery and has even progressed more recently due to the development of so-called flat panel technology that now allows to acquire CT-like images during and directly after an intervention. Thus nowadays, the diagnostic and interventional techniques and procedures have become so much entwined as to be considered a whole. PMID:23158462

MJO Simulation Diagnostics  

SciTech Connect

The Madden-Julian Oscillation (MJO) interacts with, and influences, a wide range of weather and climate phenomena (e.g., monsoons, ENSO, tropical storms, mid-latitude weather), and represents an important, and as yet unexploited, source of predictability at the subseasonal time scale. Despite the important role of the MJO in our climate and weather systems, current global circulation models (GCMs) exhibit considerable shortcomings in representing this phenomenon. These shortcomings have been documented in a number of multi-model comparison studies over the last decade. However, diagnosis of model performance has been challenging, and model progress has been difficult to track, due to the lack of a coherent and standardized set of MJO diagnostics. One of the chief objectives of the US CLIVAR MJO Working Group is the development of observation-based diagnostics for objectively evaluating global model simulations of the MJO in a consistent framework. Motivation for this activity is reviewed, and the intent and justification for a set of diagnostics is provided, along with specification for their calculation, and illustrations of their application. The diagnostics range from relatively simple analyses of variance and correlation, to more sophisticated space-time spectral and empirical orthogonal function analyses. These diagnostic techniques are used to detect MJO signals, to construct composite life-cycles, to identify associations of MJO activity with the mean state, and to describe interannual variability of the MJO.

Revisiting Tversky's diagnosticity principle.  

PubMed

Similarity is a fundamental concept in cognition. In 1977, Amos Tversky published a highly influential feature-based model of how people judge the similarity between objects. The model highlights the context-dependence of similarity judgments, and challenged geometric models of similarity. One of the context-dependent effects Tversky describes is the diagnosticity principle. The diagnosticity principle determines which features are used to cluster multiple objects into subgroups. Perceived similarity between items within clusters is expected to increase, while similarity between items in different clusters decreases. Here, we present two pre-registered replications of the studies on the diagnosticity effect reported in Tversky (1977). Additionally, one alternative mechanism that has been proposed to play a role in the original studies, an increase in the choice for distractor items (a substitution effect, see Medin et al., 1995), is examined. Our results replicate those found by Tversky (1977), revealing an average diagnosticity-effect of 4.75%. However, when we eliminate the possibility of substitution effects confounding the results, a meta-analysis of the data provides no indication of any remaining effect of diagnosticity. PMID:25161638

Efficiency of diagnostic criteria for attention deficit disorder: toward an empirical approach to designing and validating diagnostic algorithms.  

PubMed

Using structured psychiatric interviews, 73 attention deficit disorder (ADD) patients, 26 psychiatric control patients, 26 normal controls, and all available first degree relatives of these index children were examined. ADD subgroups with and without comorbid psychiatric disorders did not differ on rates of specific ADD symptoms. The construct of ADD is internally consistent as measured by Cronbach's alpha. The diagnostic efficiency of individual items is presented. A receiver operating characteristic-based procedure is used to create an ADD diagnostic algorithm that is more efficient in discriminating ADD children from controls than the DSM-III-based clinical diagnosis. Cross-validation with family study data shows this procedure to be superior to the procedure used for the DSM-III-R diagnosis. The results show that proponents of conditional probability and receiver operating characteristic analyses are correct in asserting that the examination of symptom combinations may result in better diagnostic algorithms.

Rapid diagnostic tests for malaria parasites.  

PubMed

Malaria presents a diagnostic challenge to laboratories in most countries. Endemic malaria, population movements, and travelers all contribute to presenting the laboratory with diagnostic problems for which it may have little expertise available. Drug resistance and genetic variation has altered many accepted morphological appearances of malaria species, and new technology has given an opportunity to review available procedures. Concurrently the World Health Organization has opened a dialogue with scientists, clinicians, and manufacturers on the realistic possibilities for developing accurate, sensitive, and cost-effective rapid diagnostic tests for malaria, capable of detecting 100 parasites/microl from all species and with a semiquantitative measurement for monitoring successful drug treatment. New technology has to be compared with an accepted "gold standard" that makes comparisons of sensitivity and specificity between different methods. The majority of malaria is found in countries where cost-effectiveness is an important factor and ease of performance and training is a major consideration. Most new technology for malaria diagnosis incorporates immunochromatographic capture procedures, with conjugated monoclonal antibodies providing the indicator of infection. Preferred targeted antigens are those which are abundant in all asexual and sexual stages of the parasite and are currently centered on detection of HRP-2 from Plasmodium falciparum and parasite-specific lactate dehydrogenase or Plasmodium aldolase from the parasite glycolytic pathway found in all species. Clinical studies allow effective comparisons between different formats, and the reality of nonmicroscopic diagnoses of malaria is considered. PMID:11781267

Saliva, diagnostics, and dentistry.  

PubMed

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.

Beam Diagnostics for FACET  

SciTech Connect

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.

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.

A New Diagnostic Test for Endometrial Cancer?  

PubMed Central

Objective During saline-infused sonohysterography (SIS), the distension fluid is typically discarded. If cytology analysis could identify those patients with endometrial cancer, many women would be spared from further procedures. Methods Thirty consecutive patients with clinical stage I or II endometrial adenocarcinoma were prospectively recruited preoperatively. Saline-infused sonohysterography was performed by instilling 5 mL of saline, withdrawing and sending for analysis. Saline was reinfused until complete SIS images were obtained and sent separately for cytology. Results Of the 30 women enrolled, SIS was technically successful in 29. Demographics included mean age (60.5 ± 6.99 years), body mass index (35.55 ± 8.18 kg/m2), endometrioid histology (76%), and grade (grade 1, 67%). Prestudy diagnostic method included biopsy (70%), dilatation and curettage (17%), and hysteroscopy (10%). Adequate cytology specimens were obtained in 66% of the 5mL flushes and 72% of the complete SIS collections. Of adequate specimens, the sensitivities to detect endometrial cancer for the 5-mL, complete, and combined fluid samples were 26% (95% confidence interval, 9%–51%), 36% (17%–59%), and 42% (22%–63%). Sensitivity based on the whole study sample (N = 30) was 33% (17%–53%). Statistical significance was not found in the association between a positive test and age, body mass index, grade, diagnostic method, or volume instilled or aspirated. Conclusions Most patients with early endometrial cancer can undergo SIS procedures with adequate cytology specimens obtained from distention media. However, the sensitivity is low, and refinements are necessary before utilizing as a diagnostic test. In cases with positive results, the patient may be able to avoid other costly and painful procedures. PMID:23881100

Myxofibrosarcoma (MFS) is a variant of the group of malignant fibrous histiocytomas. It is one of the most aggressive types of soft tissue neoplasms. The clinical presentation is not pathognomonic and the histological aspects are highly heterogenous, frequently delaying the diagnosis or leading to misdiagnosis. Complementary histochemical and immunohistochemical stainings are mandatory to achieve the diagnosis of MFS. A 78-year-old male patient is presented illustrating this diagnostic pitfall. Extensive surgery followed by radiotherapy is the first choice treatment. PMID:23888215

ITER Diagnostic First Wal  

SciTech Connect

The ITER Diagnostic Division is responsible for designing and procuring the First Wall Blankets that are mounted on the vacuum vessel port plugs at both the upper and equatorial levels This paper will discuss the effects of the diagnostic aperture shape and configuration on the coolant circuit design. The DFW design is driven in large part by the need to conform the coolant arrangement to a wide variety of diagnostic apertures combined with the more severe heating conditions at the surface facing the plasma, the first wall. At the first wall, a radiant heat flux of 35W/cm2 combines with approximate peak volumetric heating rates of 8W/cm3 (equatorial ports) and 5W/cm3 (upper ports). Here at the FW, a fast thermal response is desirable and leads to a thin element between the heat flux and coolant. This requirement is opposed by the wish for a thicker FW element to accommodate surface erosion and other off-normal plasma events.

Verifying Diagnostic Software  

NASA Technical Reports Server (NTRS)

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.

Alpha Particle Diagnostic  

SciTech Connect

The study of burning plasmas is the next frontier in fusion energy research, and will be a major objective of the U.S. fusion program through U.S. collaboration with our international partners on the ITER Project. For DT magnetic fusion to be useful for energy production, it is essential that the energetic alpha particles produced by the fusion reactions be confined long enough to deposit a significant fraction of their initial ~3.5 MeV energy in the plasma before they are lost. Development of diagnostics to study the behavior of energetic confined alpha particles is a very important if not essential part of burning plasma research. Despite the clear need for these measurements, development of diagnostics to study confined the fast confined alphas to date has proven extremely difficult, and the available techniques remain for the most part unproven and with significant uncertainties. Research under this grant had the goal of developing diagnostics of fast confined alphas, primarily based on measurements of the neutron and ion tails resulting from alpha particle knock-on collisions with the plasma deuterium and tritium fuel ions. One of the strengths of this approach is the ability to measure the alphas in the hot plasma core where the interesting ignition physics will occur.

Future of diagnostic microbiology.  

PubMed

Diagnostic Microbiology is the tool that makes it possible to identify the exact etiology of infectious diseases and the most optimal therapy at the level of individual patients as well as communities. Conventional methods require time to grow the microbes in vitro under specific conditions and not all microbes are easily cultivable. This is followed by biochemical methods for identification which also require hours and sometimes days. Transport of the specimens under less than ideal conditions, prior use of antibiotics and small number of organisms are among the factors that render culture-based methods less reliable. Newer methods depend on amplification of nucleic acids followed by use of probes for identification. This mitigates the need for higher microbial load, presence of metabolically active viable organisms and shortens the time to reporting. These methods can be used to detect antibiotic resistance genes directly from the specimen and help direct targeted therapy. Since these methods will not fulfill all the diagnostic needs, a second approach is being used to shorten the time to identification after the organism has already grown. Mass spectrometry and bioinformatics are the tools making this possible. This review gives a historical perspective on diagnostic microbiology, discusses the pitfalls of current methodology and provides an overview of newer and future methods. PMID:25297019

PML diagnostic criteria  

PubMed Central

Objective: To establish criteria for the diagnosis of progressive multifocal leukoencephalopathy (PML). Methods: We reviewed available literature to identify various diagnostic criteria employed. Several search strategies employing the terms “progressive multifocal leukoencephalopathy” with or without “JC virus” were performed with PubMed, SCOPUS, and EMBASE search engines. The articles were reviewed by a committee of individuals with expertise in the disorder in order to determine the most useful applicable criteria. Results: A consensus statement was developed employing clinical, imaging, pathologic, and virologic evidence in support of the diagnosis of PML. Two separate pathways, histopathologic and clinical, for PML diagnosis are proposed. Diagnostic classification includes certain, probable, possible, and not PML. Conclusion: Definitive diagnosis of PML requires neuropathologic demonstration of the typical histopathologic triad (demyelination, bizarre astrocytes, and enlarged oligodendroglial nuclei) coupled with the techniques to show the presence of JC virus. The presence of clinical and imaging manifestations consistent with the diagnosis and not better explained by other disorders coupled with the demonstration of JC virus by PCR in CSF is also considered diagnostic. Algorithms for establishing the diagnosis have been recommended. PMID:23568998

Obturator hernia: A diagnostic challenge  

PubMed Central

Patient: Female, 90 Final Diagnosis: Obturator hernia Symptoms: Epigastric pain • vomiting Medication: — Clinical Procedure: — Specialty: Gastroenterology and Hepatology Objective: Challenging differential diagnosis Background: Obturator hernia (OH) can be difficult to diagnose because it shows only nonspecific signs and symptoms. Although pain in a lower limb caused by compression of the obturator nerve by the hernia in the obturator canal (Howship-Romberg sign) is a characteristic sign, its presence is rather rare. Case Report: We herein describe the case of a 90-year-old woman with an OH that was difficult to diagnose because of her slight abdominal signs and symptoms on admission and subtle abdominal computed tomography (CT) findings. Although the CT images revealed the presence of an OH, this finding was overlooked because it contained only a part of the small intestine wall, which is called the Richter type. Fortunately, her condition improved dramatically with only conservative treatment. Conclusions: Although early diagnosis is essential to reduce morbidity and mortality, OH can be a diagnostic challenge even with abdominal CT. PMID:25006359

Diagnostics for multiple regression problems  

SciTech Connect

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.

The Indian Health Service (IHS) operates or contracts with Tribal groups to operate 50 hospitals and approximately 165 primary ambulatory care centers. These facilities contain approximately 275 medical and 800 dental diagnostic x-ray machines. IHS environmental health personnel in collaboration with the Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH) developed a diagnostic x-ray protection program including standard survey procedures and menu-driven calculations software. Important features of the program include the evaluation of equipment performance collection of average patient entrance skin exposure (ESE) measurements for selected procedures, and quality assurance. The ESE data, collected using the National Evaluation of X-ray Trends (NEXT) protocol, will be presented. The IHS Diagnostic X-ray Radiation Protection Program is dynamic and is adapting to changes in technology and workload.

Diagnostic utility of cholescintigraphy and ultrasonography in acute cholecystitis  

SciTech Connect

When faced with a patient with possible acute cholecystitis, technetium-99m-HIDA scintigraphy should be the primary diagnostic procedure performed. If scintigraphy reveals a normal gallbladder, acute cholecystitis is excluded. If the scintigram fails to visualize the gallbladder, ultrasonography is deemed advisable to exclude potential false-positive scintigrams and confirm the presence of cholelithiasis.

[Diagnostic kits in parasitology: which controls?].  

PubMed

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.

Photon diagnostics for the X-ray FELs at TESLA  

NASA Astrophysics Data System (ADS)

An X-ray diagnostic station will be installed for each of the XFEL undulator beamlines at TESLA. Primary purpose of the X-ray diagnostics is to provide an additional tool for alignment and commissioning of the numerous undulator cells along an XFEL beamline independently from electron-beam-based alignment procedures. Both methods will complement one another. The X-ray diagnostic station will be a sensitive instrument generating essential input for the undulator control system. The diagnostic station will be located about 120 m downstream from the last undulator cell. Total flux measurements will verify the XFEL's gain. Analysis of the spectral and spatial distribution of the spontaneous radiation of individual or several consecutive undulator segments will be used to optimize angle and position of the electron beam trajectory, to verify the magnetic gap, and to adjust the phase match between two undulator segments. The two latter purposes cannot be served by electron-beam-based alignment.

New Polarization Diagnostics for the Solar Atmosphere  

NASA Astrophysics Data System (ADS)

We present relatively new diagnostics of ``weak" magnetic fields in the solar atmosphere. The first diagnostic is suggested by recent advances in the inversion of Stokes profiles of lines formed by resonance scattering in the weakly magnetized plasma of prominences (Hanle effect and level-crossing; 0 to 100 G). Use of pattern recognition techniques (PCA) in this field has marked a sensible progress with respect to previous diagnostic procedures. The second diagnostic is the modelling of hyperfine structured (HFS) lines that can be observed in the spectrum of the quiet photosphere. This allows to investigate relatively weak photospheric fields (200 G to 1000 G), in which regime the HFS induces peculiar signatures in the Stokes profiles, including the appearance of subcomponents and net circular polarization. The third diagnostic is suggested by interesting polarization properties of the Na I D1 line formed by resonance scattering: the atomic polarization in the upper level of D1, which is responsible of a characteristic antisymmetric (i.e., V-like) signature in the core of Stokes Q, is rapidly suppressed for B > 10 G, irrespective of the magnetic field direction. A common denominator of these three diagnostics is their sensitivity to the actual strength of the magnetic field, instead of the magnetic flux within the resolution element. Another common aspect is that all require (or would profit from) high polarization sensitivity, which will be one of the strengths of ATST. For the diagnostics of prominence magnetic fields, the possibility of multiline spectropolarimetry could be decisive. Simultaneous observations of He I D3 (5876A) and 10830A, or of He I D3 and the Na I D lines (all within a 20A spectral range!), would increase the inversion accuracy of PCA. The high spatial resolution capabilities of ATST would be advantageous mostly to diagnose weak photospheric fields, already at the present time. Because of the complexity of radiative transfer in complicated structures like prominences, high spatial resolution in these structures is not the highest priority. However, we hope that when ATST will become operative, this complicated problem will have been attacked succesfully.

Diagnostic imaging in pediatric renal inflammatory disease  

SciTech Connect

Some form of imaging procedure should be used to document the presence of infection of the upper urinary tract in troublesome cases in children. During the past several years, sonography, nuclear radiology, and computed tomography (CT) have had a significant influence on renal imaging. The purpose of this article is to reevaluate the noninvasive imaging procedures that can be used to diagnose pediatric renal inflammatory disease and to assess the relative value of each modality in the various types of renal infection. The authors will not discuss the radiologic evaluation of the child who has had a previous renal infection, in whom cortical scarring or reflux nephropathy is a possibility; these are different clinical problems and require different diagnostic evaluation.

Planetary Transmission Diagnostics  

NASA Technical Reports Server (NTRS)

This report presents a methodology for detecting and diagnosing gear faults in the planetary stage of a helicopter transmission. This diagnostic technique is based on the constrained adaptive lifting algorithm. The lifting scheme, developed by Wim Sweldens of Bell Labs, is a time domain, prediction-error realization of the wavelet transform that allows for greater flexibility in the construction of wavelet bases. Classic lifting analyzes a given signal using wavelets derived from a single fundamental basis function. A number of researchers have proposed techniques for adding adaptivity to the lifting scheme, allowing the transform to choose from a set of fundamental bases the basis that best fits the signal. This characteristic is desirable for gear diagnostics as it allows the technique to tailor itself to a specific transmission by selecting a set of wavelets that best represent vibration signals obtained while the gearbox is operating under healthy-state conditions. However, constraints on certain basis characteristics are necessary to enhance the detection of local wave-form changes caused by certain types of gear damage. The proposed methodology analyzes individual tooth-mesh waveforms from a healthy-state gearbox vibration signal that was generated using the vibration separation (synchronous signal-averaging) algorithm. Each waveform is separated into analysis domains using zeros of its slope and curvature. The bases selected in each analysis domain are chosen to minimize the prediction error, and constrained to have the same-sign local slope and curvature as the original signal. The resulting set of bases is used to analyze future-state vibration signals and the lifting prediction error is inspected. The constraints allow the transform to effectively adapt to global amplitude changes, yielding small prediction errors. However, local wave-form changes associated with certain types of gear damage are poorly adapted, causing a significant change in the prediction error. The constrained adaptive lifting diagnostic algorithm is validated using data collected from the University of Maryland Transmission Test Rig and the results are discussed.

MAST magnetic diagnostics  

NASA Astrophysics Data System (ADS)

The mega-ampere spherical tokamak (MAST) experiment is a new, large, low aspect ratio device (R=0.7-0.8 m, a=0.5-0.65 m, maximum BT˜0.63 T at R=0.7 m) operating its first experimental physics campaign. Designed to study a wide variety of plasma shapes with up to 2 MA of plasma current with an aspect ratio down to 1.3, the poloidal field (PF) coils used for plasma formation, equilibrium and shaping are inside the main vacuum vessel. For plasma control and to investigate a wide range of plasma phenomena, an extensive set of magnetic diagnostics have been installed inside the vacuum vessel. More than 600 vacuum compatible, bakeable diagnostic coils are configured in a number of discrete arrays close to the plasma edge with about half the coils installed behind the graphite armour tiles covering the center column. The coil arrays measure the toroidal and poloidal variation in the equilibrium field and its high frequency fluctuating components. Internal coils also measure currents in the PF coils, plasma current, stored energy and induced currents in the mechanical support structures of the coils and graphite armour tiles. The latter measurements are particularly important when halo currents are induced following a plasma termination, for example, when the plasma becomes vertically unstable. The article describes the MAST magnetic diagnostic coil set and their calibration. The way in which coil signals are used to control the plasma equilibrium is described and data from the first MAST experimental campaign presented. These coil data are used as input to the code EFIT [L. Lao et al., Nucl. Fusion 25, 1611 (1985)], for measurement of halo currents in the vacuum vessel structure and for measurements of the structure of magnetic field fluctuations near the plasma edge.

Injuries of the wrist are difficult to diagnose because of the complex and narrow anatomic structures. Based on precise clinical examination, X-rays, CT, and MRI are valuable additional tools that can be used. If a fracture is suspected a CT scan is preferable. In the case of a suspected soft tissue or ligamentous injury and non-vital fragments or necrosis MRI is suitable. Other diagnostic tools are presently of minor importance for the wrist. Technical innovations allow better visualization and classification of lesions. However, exact knowledge of the tools is important. PMID:14727035

Myxofibrosarcoma: A Diagnostic Pitfall  

PubMed Central

Abstract Myxofibrosarcoma (MFS) is a variant of the group of malignant fibrous histiocytomas. It is one of the most aggressive types of soft tissue neoplasms. The clinical presentation is not pathognomonic and the histological aspects are highly heterogenous, frequently delaying the diagnosis or leading to misdiagnosis. Complementary histochemical and immunohistochemical stainings are mandatory to achieve the diagnosis of MFS. A 78-year-old male patient is presented illustrating this diagnostic pitfall. Extensive surgery followed by radiotherapy is the first choice treatment. PMID:23888215

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.

Outcomes of scapula stabilization in obstetrical brachial plexus palsy: a novel dynamic procedure for correction of the winged scapula.  

PubMed

Among the late consequences of obstetrical brachial plexus palsy is winging of the scapula, a functional and aesthetic deformity. This article introduces a novel surgical procedure for the dynamic correction of this clinical entity that involves the dynamic transfer of the contralateral trapezius muscle and/or rhomboid muscles and anchoring to the affected scapula. In more severe cases of scapula winging, the contralateral latissimus dorsi muscle may also need to be transferred to achieve dynamic scapula stabilization. The outcomes of this novel surgical procedure were analyzed in relation to the effect on abduction, external rotation, growth of the scapula, and distance of the scapula from the posterior midline. The results were analyzed in 26 patients who underwent this procedure and had adequate follow-up. The mean patient age was 6.39 years. Fourteen (54 percent) had a diagnosis of Erb palsy, and 12 (46 percent) had a diagnosis of global paralysis. All 26 patients had an additional secondary procedure performed prior to or simultaneously with the scapula stabilization procedure. In 19 patients, the contralateral trapezius was transferred and anchored to the medial border of the winged scapula alone, but in seven cases the underlying rhomboid major was transferred along with the trapezius muscle to provide sufficient scapula stabilization. In five cases in which the scapula winging was severe, the contralateral latissimus dorsi muscle was transferred at a second stage. After this procedure, all patients demonstrated improved scapula symmetry. The mean increase in abduction was 18 degrees (p < 0.001), the mean increase in external rotation was 19 degrees (p < 0.001), and the mean increase in anterior flexion was 12 degrees (p = 0.015). The improvement of the relative position of the winged scapula on the posterior thorax was analyzed by measuring the distance of the inferior angle of both scapulae from the midline, then calculating the difference between normal and affected sides and comparing this value before and after the scapula stabilization procedure. This value preoperatively was 3.24 cm; postoperatively it decreased to 0.36 cm (p < 0.001), demonstrating a statistically significant improvement. PMID:11818835

Diagnostic Oligonucleotide Microarray Fingerprinting of Bacillus Isolates  

SciTech Connect

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.

Capillary electrophoresis: new technology for DNA diagnostics.  

PubMed

New innovations in the diagnostic laboratory achieve their full potential when they can be automated. Increasingly molecular biology (DNA) techniques are being utilised in traditional pathology disciplines, as well as the more recent ones of cytogenetics and molecular genetics. Molecular biology was first exploited for diagnostic purposes when Southern blotting became established. However the time-consuming nature of the methodology, as well as the skills required, made it difficult for Southern blotting to be used routinely in the service laboratory. Subsequently the invention of PCR facilitated the approach to DNA diagnostics. Today PCR in commercial or home-made kits is used for a range of procedures. The steps required to amplify DNA with PCR can also be fully automated. However the analysis of PCR products, which frequently requires slab gel electrophoresis and toxic chemicals or radioisotopes for visualisation, remains difficult to automate. An alternative way for analysing PCR products is now available through capillary electrophoresis. With this technique, automation can be extended to sample loading, electrophoresis and data analysis. The use of toxic chemicals or radioisotopes can be avoided. PMID:9770198

Surgical procedures for voice restoration serve to improve oral communication by better vocal function. They comprise of phonomicrosurgery, with direct and indirect access to the larynx; laryngoplasty; laryngeal injections; and surgical laryngeal reinnervation. The basis for modern surgical techniques for voice disorders is the knowledge about the ultrastructure of the vocal folds and the increasing experience of surgeons in voice surgery, while facing high social and professional demands on the voice. Vocal activity limitation and participation restriction has become more important in the artistic and social areas. A number of surgical methods that have been developed worldwide for this reason, are presented in this article. Functional oriented surgery has to meet high standards. The diagnostics of vocal function has to be multi-dimensional in order to determine the indication and the appropriate surgical intervention. PMID:22073062

TFTR Poloidal Rotation Diagnostic  

NASA Astrophysics Data System (ADS)

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.

Diagnostic algorithm for syncope.  

PubMed

Syncope is a common symptom with many causes. Affecting a large proportion of the population, both young and old, it represents a significant healthcare burden. The diagnostic approach to syncope should be focused on the initial evaluation, which includes a detailed clinical history, physical examination and 12-lead electrocardiogram. Following the initial evaluation, patients should be risk-stratified into high or low-risk groups in order to guide further investigations and management. Patients with high-risk features should be investigated further to exclude significant structural heart disease or arrhythmia. The ideal currently-available investigation should allow ECG recording during a spontaneous episode of syncope, and when this is not possible, an implantable loop recorder may be considered. In the emergency room setting, acute causes of syncope must also be considered including severe cardiovascular compromise due to pulmonary, cardiac or vascular pathology. While not all patients will receive a conclusive diagnosis, risk-stratification in patients to guide appropriate investigations in the context of a diagnostic algorithm should allow a benign prognosis to be maintained.

Diagnostic criteria for sarcoidosis.  

PubMed

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.

Laboratory Diagnostics of Botulism  

PubMed Central

Botulism is a potentially lethal paralytic disease caused by botulinum neurotoxin. Human pathogenic neurotoxins of types A, B, E, and F are produced by a diverse group of anaerobic spore-forming bacteria, including Clostridium botulinum groups I and II, Clostridium butyricum, and Clostridium baratii. The routine laboratory diagnostics of botulism is based on the detection of botulinum neurotoxin in the patient. Detection of toxin-producing clostridia in the patient and/or the vehicle confirms the diagnosis. The neurotoxin detection is based on the mouse lethality assay. Sensitive and rapid in vitro assays have been developed, but they have not yet been appropriately validated on clinical and food matrices. Culture methods for C. botulinum are poorly developed, and efficient isolation and identification tools are lacking. Molecular techniques targeted to the neurotoxin genes are ideal for the detection and identification of C. botulinum, but they do not detect biologically active neurotoxin and should not be used alone. Apart from rapid diagnosis, the laboratory diagnostics of botulism should aim at increasing our understanding of the epidemiology and prevention of the disease. Therefore, the toxin-producing organisms should be routinely isolated from the patient and the vehicle. The physiological group and genetic traits of the isolates should be determined. PMID:16614251

This technique uses 2 occlusal acrylic resin devices to transfer the diagnostic cast information to the definitive casts. Esthetic and functional fixed dental prostheses are fabricated from diagnostic information acquired in the presurgical phase without any impression or recording of the maxillomandibular relationship during or after surgery. This methodology is applicable when the simultaneous immediate loading of implants in 2 edentulous arches is indicated. PMID:24882596

No single procedure or group of procedures can be applied to all patients with AAFD because of the variety of underlying etiology and grades of deformity. As the posture of the foot progresses into hindfoot valgus and forefoot abduction through attenuation of the medial structures of the foot, the medial column begins to change shape. The first ray elevates and the joints of the medial column may begin to collapse. Careful physical examination and review of weight-bearing radiographs determines which patients have an associated forefoot varus deformity that may require correction at the time of flatfoot reconstruction. Correction of an AAFD requires a combination of soft-tissue procedures to restore dynamic inversion power and bony procedures to correct the hindfoot and midfoot malalignments. If after these corrections forefoot varus deformity remains, the surgeon should consider use of a medial column procedure to recreate the “triangle of support” of the foot that Cotton described.5 If the elevation of the medial column is identified to be at the first NC or the first TMT joint, then the joint should be carefully examined for evidence of instability, hypermobility, or arthritic change. If none of these problems exist, then the surgeon can consider use of the joint-sparing Cotton medial cuneiform osteotomy to correct residual forefoot varus. However, if instability, hypermobility, or arthritic change is present, then the surgeon should consider use of an arthrodesis of the involved joint to correct residual forefoot varus. Either procedure provides a safe and predictable correction to the medial column as part of a comprehensive surgical correction of AAFD. PMID:22541526

Balloon gondola diagnostics package  

NASA Technical Reports Server (NTRS)

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.

The revolution in molecular biology and molecular genetics has begun to reveal the sequence of events that links genes and disease. As a result of activities such as the Human Genome Project, a parallel revolution in technology is bringing nearer to hand the possibility of readily available genetic diagnostics. Genetic testing services have begun to move out of the academic medical centers and into the private enterprise arena. Under these circumstances it is important to understand the factors affecting the availability and application of this powerful predictive tool in a for-profit mode. How does the marketplace encourage or discourage genetic testing? Will the same market influences that generate pharmaceutical sales be operating to "sell" genetic tests? PMID:11654185

Rig Diagnostic Tools  

NASA Technical Reports Server (NTRS)

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.

Mobile tumours in the lumbar spinal canal: a diagnostic problem  

PubMed Central

In two cases of mobile tumours in the lumbar spinal canal there was difficulty and delay in clinical and radiologic diagnosis because the early symptoms did not correspond to any particular dermatome. Myelography and computed tomography (CT) are the initial diagnostic procedures used in most institutions, even where magnetic resonance imaging (MRI) is available. The purpose of these 2 case reports is to remind clinicians that it is possible for certain tumours attached to the roots in the lumbar spinal canal to migrate, because the roots tend to be redundant or lax. Multilevel search is essential in neuroradiologic studies for early diagnostic confirmation of mobile tumours. PMID:9030087

Diagnostic strategies in osteomyelitis  

SciTech Connect

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.

Meta-analysis and meta-modelling for diagnostic problems  

PubMed Central

Background A proportional hazards measure is suggested in the context of analyzing SROC curves that arise in the meta–analysis of diagnostic studies. The measure can be motivated as a special model: the Lehmann model for ROC curves. The Lehmann model involves study–specific sensitivities and specificities and a diagnostic accuracy parameter which connects the two. Methods A study–specific model is estimated for each study, and the resulting study-specific estimate of diagnostic accuracy is taken as an outcome measure for a mixed model with a random study effect and other study-level covariates as fixed effects. The variance component model becomes estimable by deriving within-study variances, depending on the outcome measure of choice. In contrast to existing approaches – usually of bivariate nature for the outcome measures – the suggested approach is univariate and, hence, allows easily the application of conventional mixed modelling. Results Some simple modifications in the SAS procedure proc mixed allow the fitting of mixed models for meta-analytic data from diagnostic studies. The methodology is illustrated with several meta–analytic diagnostic data sets, including a meta–analysis of the Mini–Mental State Examination as a diagnostic device for dementia and mild cognitive impairment. Conclusions The proposed methodology allows us to embed the meta-analysis of diagnostic studies into the well–developed area of mixed modelling. Different outcome measures, specifically from the perspective of whether a local or a global measure of diagnostic accuracy should be applied, are discussed as well. In particular, variation in cut-off value is discussed together with recommendations on choosing the best cut-off value. We also show how this problem can be addressed with the proposed methodology.

The tissue diagnostic instrument  

NASA Astrophysics Data System (ADS)

Tissue mechanical properties reflect extracellular matrix composition and organization, and as such, their changes can be a signature of disease. Examples of such diseases include intervertebral disk degeneration, cancer, atherosclerosis, osteoarthritis, osteoporosis, and tooth decay. Here we introduce the tissue diagnostic instrument (TDI), a device designed to probe the mechanical properties of normal and diseased soft and hard tissues not only in the laboratory but also in patients. The TDI can distinguish between the nucleus and the annulus of spinal disks, between young and degenerated cartilage, and between normal and cancerous mammary glands. It can quantify the elastic modulus and hardness of the wet dentin left in a cavity after excavation. It can perform an indentation test of bone tissue, quantifying the indentation depth increase and other mechanical parameters. With local anesthesia and disposable, sterile, probe assemblies, there has been neither pain nor complications in tests on patients. We anticipate that this unique device will facilitate research on many tissue systems in living organisms, including plants, leading to new insights into disease mechanisms and methods for their early detection.

Stellar population synthesis diagnostics  

NASA Astrophysics Data System (ADS)

A quantitative method is presented to compare observed and synthetic colour-magnitude diagrams (CMDs). The method is based on a chi (2) merit function for a point (c_i,m_i) in the observed CMD, which has a corresponding point in the simulated CMD within nsigma (c_i,m_i) of the error ellipse. The chi (2) merit function is then combined with the Poisson merit function of the points for which no corresponding point was found within the nsigma (c_i,m_i) error ellipse boundary. Monte-Carlo simulations are presented to demonstrate the diagnostics obtained from the combined (chi (2) , Poisson) merit function through variation of different parameters in the stellar population synthesis tool. The simulations indicate that the merit function can potentially be used to reveal information about the initial mass function. Information about the star formation history of single stellar aggregates, such as open or globular clusters and possibly dwarf galaxies with a dominating stellar population, might not be reliable if one is dealing with a relatively small age range.

Fundamentals of diagnostic ultrasonography.  

PubMed

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

Due to increasing knowledge on pathogenetic factors causing osteoporosis and increasingly more detailed investigations, the diagnosis of secondary osteoporosis is being made increasingly more often. A rational search for the underlying disease or the bone-damaging medication is indicated particularly in adolescents, premenopausal women, men and postmenopausal women with rapidly decreasing bone tissue. The early detection of the causative disease in the preclinical stage of osteoporosis and the current therapeutic options allow not only normalization of the bone structure and the risk of fracture but also targeted therapy of the cause of the osteoporosis. The focal point in the diagnostics of secondary osteoporosis is still dual energy X-ray absorptiometry (DXA) measurement together with the manifold imaging procedures in radiology and additional clinical, laboratory chemical and bioptic findings.

Nipple discharge: current diagnostic and therapeutic approaches.  

PubMed

Nipple discharge is a complex diagnostic challenge for the clinician. A variety of diseases (such as intraductal papillomas, mammary duct ectasia, breast cancer, pituitary adenomas, breast abscesses/infections, etc.) can manifest as nipple discharge. The importance of nipple discharge for both the patient and the physician is the possible association of this condition with an underlying carcinoma. With heightened public awareness of breast cancer, an increasing number of women are asking their health care providers about nipple discharge. A detailed clinical evaluation is invaluable to determine the pathophysiology, assess the risk of malignancy, and plan treatment of the patient with nipple discharge. A combination of diagnostic tests, including mammography, breast ultrasonography, and possibly galactography can help the clinician to establish the diagnosis and plan proper management. Depending on the underlying breast pathology, a central or single lactiferous duct excision is the procedure of choice. Breast carcinoma associated with nipple discharge should be treated by either a modified radical mastectomy of breast-conservation therapy (i.e. duct-lobular segmentectomy with adequate, free margins [ideally>1cm], levels I and II axillary lymph node dissection, followed by breast irradiation).

Children's Exposure to Diagnostic Medical Radiation and Cancer Risk: Epidemiologic and Dosimetric Considerations  

PubMed Central

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.

Microsoft Academic Search

In this paper, we first present an analysis of pro- cedural question structure. Next, we investigate the structure of procedural texts and of the relevant rhetorical relations of interest for answering ques- tions. We then show how, from a linguistic point of view, questions and procedural text fragments can match in order to produce responses.

Musculoskeletal symptoms and orthopaedic complications in pregnancy: pathophysiology, diagnostic approaches and modern management.  

PubMed

Low back pain is a common musculoskeletal symptom in pregnancy that can present as lumbar pain or pelvic girdle pain, with significant physical and psychosocial implications. Pelvic girdle pain is more prevalent and results in greater disability than lumbar pain. It is possible to distinguish between these two conditions from a detailed history based on the site of the pain, its intensity, disability and pain provocation tests. Management of low back pain in pregnancy is conservative, with physical exercise for lumbar pain and minimising activities that exacerbate pain, analgesics and bed rest for pelvic girdle pain, as well as avoiding abduction beyond the pain-free zone in labour. There is evidence that stabilising exercises in patients with pelvic girdle pain postpartum have a beneficial effect. Other treatment modalities that have been shown to be safe and effective include pelvic belts, transcutaneous electrical nerve stimulation, spinal manipulative therapy, acupuncture and complementary therapy with yoga. Other orthopaedic complications in pregnancy such as carpal tunnel syndrome, pubic symphysis rupture, transient osteoporosis and osteonecrosis are usually self-limiting with a satisfactory outcome. However, a lack of awareness and failure to recognise these complications can result in long-term morbidity. Knowledge of the preoperative diagnostic investigations, surgical approaches and intraoperative positioning of the mother to avoid gravid uterus compression is vital in orthopaedic emergencies such as lumbar disc herniation, cauda equina syndrome, fractures and acute compartment syndrome of the lower limb to ensure a safe maternal and fetal outcome and to prevent serious disability. Pregnancy is not contraindicated in women with pre-existing orthopaedic complications such as kyphoscoliosis and total hip arthroplasty as there is no evidence to suggest increased maternal or fetal risks.

Intrasurgical diagnostics of lymphatic nodes metastasis using laser-induced autofluorescence  

NASA Astrophysics Data System (ADS)

New method of intrasurgical diagnostics of metastasis in lymphatic nodes is based on the determination of investigated tissue autofluorescence spectra peculiarities. Statistical data demonstrate correlations between criteria of spectral analysis and morphological data. High sensitivity of spectroscopical technique, good choice of laser source for autofluorescence excitation (HeNe laser (lambda) equals 633 nm) and convenient non-invasive procedure of express diagnostics provide identification of metastasis presence in lymphatic nodes with a specifity 95%.

PubMed

Nerve transfer is the only possibility for nerve repair in cases of the brachial plexus traction injuries with spinal roots avulsion. From 1980. until 2000. in Institute of Neurosurgery, Clinical Center of Serbia, nerve transfer has been performed in 127(79%) of 159 patients with traction injuries of brachial plexus, i.e., 204 reinnervation procedures has been performed using different donor nerves. We achieved good or satisfactory arm abduction and full range or satisfactory elbow flexion through reinnervation of the axillary and musculocutaneous nerve using different donor nerves in 143 of 204 reinnervations, which presents general rate of useful functional recovery in 70.1% of cases. Mean values of the rate of useful functional recovery in individual modalities of nerve transfer in our series are 50.1% for intercostal and/or spinal accessory nerve transfer, 64.5% for plexo-plexal nerve transfer, 81.7% for regional nerve transfer, and 87.1% for combine nerve transfer.

Hemisensory syndrome is associated with a low diagnostic yield and a nearly uniform benign prognosis  

PubMed Central

Objective: To describe the diagnostic yield and prognosis for patients with hemisensory syndrome. Background: The aetiology, utility of diagnostic procedures, and outcome of hemisensory syndrome in patients with exclusive hemibody complaints having only subjective sensory abnormalities on examination is unknown. Methods: Patients were prospectively identified with hemisensory syndrome in a tertiary care institution from 1998–2002. Diagnostic procedures were analysed for sensitivity and clinical follow up was performed. Results: Thirty four patients, 25 (74%) women, of age 35 (SD 11) years were identified. The hemisensory syndrome occurred on the left side in 23 (68%) cases. Neuroimaging of the brain demonstrated diagnostic abnormalities representing ischaemic aetiology in one case. Other diagnostic testing including cerebrospinal fluid examination, electrophysiological testing, carotid ultrasonography, echocardiography, and blood testing revealed no diagnostic abnormalities. Sixteen patients (47%) continued to complain of hemisensory difficulties after all investigations were completed at 9.6 (5.8) days. One patient with a history of systemic lupus erythematosus and positive antiphospholipid antibodies had a second event diagnosed as stroke seven months after presentation. Clinical follow up at 16 (7) months revealed persisting symptoms in 6 (20%) of 30 patients. Six (50%) of 12 patients agreeing to psychiatric assessment received diagnoses of personality or mood disorders. Conclusions: Diagnostic yield in hemisensory syndrome is low, and prognosis is almost always uniformly benign. The author advocates careful assessment of medical history and consideration for neuroimaging in this group of patients. PMID:12876246

Enhanced NIF neutron activation diagnostics  

SciTech Connect

The NIF neutron activation diagnostic suite relies on removable activation samples, leading to operational inefficiencies and a fundamental lower limit on the half-life of the activated product that can be observed. A neutron diagnostic system measuring activation of permanently installed samples could remove these limitations and significantly enhance overall neutron diagnostic capabilities. The physics and engineering aspects of two proposed systems are considered: one measuring the {sup 89}Zr/{sup 89m}Zr isomer ratio in the existing Zr activation medium and the other using potassium zirconate as the activation medium. Both proposed systems could improve the signal-to-noise ratio of the current system by at least a factor of 5 and would allow independent measurement of fusion core velocity and fuel areal density.

Neurologic complications of cardiac tests and procedures.  

PubMed

Arterial or central venous vascular access is the cornerstone of invasive cardiac diagnosis, monitoring, and therapeutics. Although procedural safety has significantly improved with protocols perfected over decades of use, their prevalence renders even the uncommon neurologic complication clinically relevant. Serious peripheral nerve complications result from direct or indirect nerve injuries in the setting of a hematoma or compartment syndrome. Functional outcome is dependent upon prompt diagnosis and early treatment, so proceduralists should be aware of the relevant anatomy and early signs of nerve injury. Ischemic stroke is the most common central nervous system complication of diagnostic and therapeutic cardiac catheterization, and is presumed to be due to embolization of atherosclerotic plaque or thrombus dislodged during guiding catheter manipulation, platelet-fibrin thrombus that forms on the catheters, or air that appears during catheter flushing. Acute neurologic deterioration after thrombolysis for acute myocardial infarction should be presumed to be an intracranial hemorrhage until proven otherwise. The ideal angiography suite of the future is patientcentric and multipurpose, coordinating diagnostic and therapeutic strategies for multivascular disease, allowing for multispecialty collaboration, and, in the event of a neurologic complication of a cardiac procedure, facilitating the various treating physicians to converge efficiently upon the patient.

[The EXIT procedure].  

PubMed

The ex utero intrapartum treatment (EXIT) procedure is used for unborn fetuses in cases of predictable complications of postpartum airway obstruction. Indications for the EXIT procedure are fetal neck tumors, obstruction of the trachea, hiatus hernia of the diaphragm and congenital high airway obstruction syndrome (CHAOS). Large cervical tumors prevent normal delivery of a fetus due to reclination of the head with airway obstruction. Therefore, a primary caesarean section or the EXIT procedure has to be considered. The EXIT procedure has time limitations as the blood supply by the placenta only lasts for 30-60 min. Airway protection has to be ensured during parturition.This article reports the case of an unborn fetus with a large cervical teratoma where an obstruction of the cervical airway was detected and monitored by ultrasound and magnetic resonance imaging (MRI) during pregnancy. The EXIT procedure was therefore used and successfully accomplished. The features of the interdisciplinary aspects of the EXIT procedure are described with the special aspects of each medical discipline. PMID:23780516

This paper describes the procedures for setting up the transfer lines for the Spallation Neutron Source (SNS). The High Energy Beam Transfer (HEBT) is about 170 meters long and has two achromat sections, an energy corrector cavity, energy spreader cavity, and transverse and longitudinal collimators. The Ring to Target Beam Transfer (RTBT) line is about 150 meters long has an achromat, transverse collimators and a beam spreader section. It will be shown that with the available diagnostics one can first characterize the incoming beam in both lines and then, with types and locations of the diagnostics and beam tuning ''knobs'', set up to deliver an output beam with the desired properties.

Diagnostic testing for Giardia infections.  

PubMed

The traditional method for diagnosing Giardia infections involves microscopic examination of faecal specimens for Giardia cysts. This method is subjective and relies on observer experience. From the 1980s onwards, objective techniques have been developed for diagnosing Giardia infections, and are superseding diagnostic techniques reliant on microscopy. Detection of Giardia antigen(s) by immunoassay is the basis of commercially available diagnostic kits. Various nucleic acid amplification techniques (NAATs) can demonstrate DNA of Giardia intestinalis, and have the potential to become standard approaches for diagnosing Giardia infections. Of such techniques, methods involving either fluorescent microspheres (Luminex) or isothermal amplification of DNA (loop-mediated isothermal amplification; LAMP) are especially promising.

Patient Dose in Diagnostic Radiology  

NASA Astrophysics Data System (ADS)

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.

[Lower body contouring procedures].  

PubMed

Indications for most forms of abdominoplasty are slight weight fluctuations or pregnancy. The steadily increasing number of patients with greater weight loss as well as the growing number of bariatric operations subsequently leads to a significant increase in body contouring procedures and places new challenges on plastic surgeons. After major weight loss patients present with extremely variable deformities in the lower and upper trunk as well as the extremities, which have to be treated individually with an appropriate procedure. The restoration of the lower trunk presents the first stage of the entire reconstruction process. The various modifications of abdominoplasty procedures with their various incision patterns and scar courses and the circumferential lower trunk dermatolipectomy represent advanced operations for every individual case. Plastic surgeons should be fully aware of differences and indications of every available procedure in the area of the lower trunk and should have the ability to offer the entire repertory for each individual deformity. A high postoperative patient satisfaction results from a customized procedure selection, the optimal implementation with a correspondingly low rate of complications and above-average patient care.

The Buffer Diagnostic Prototype: A fault isolation application using CLIPS  

NASA Technical Reports Server (NTRS)

This paper describes problem domain characteristics and development experiences from using CLIPS 6.0 in a proof-of-concept troubleshooting application called the Buffer Diagnostic Prototype. The problem domain is a large digital communications subsystems called the real-time network (RTN), which was designed to upgrade the launch processing system used for shuttle support at KSC. The RTN enables up to 255 computers to share 50,000 data points with millisecond response times. The RTN's extensive built-in test capability but lack of any automatic fault isolation capability presents a unique opportunity for a diagnostic expert system application. The Buffer Diagnostic Prototype addresses RTN diagnosis with a multiple strategy approach. A novel technique called 'faulty causality' employs inexact qualitative models to process test results. Experimental knowledge provides a capability to recognize symptom-fault associations. The implementation utilizes rule-based and procedural programming techniques, including a goal-directed control structure and simple text-based generic user interface that may be reusable for other rapid prototyping applications. Although limited in scope, this project demonstrates a diagnostic approach that may be adapted to troubleshoot a broad range of equipment.

Too much of a good thing is wonderful? A conceptual analysis of excessive examinations and diagnostic futility in diagnostic radiology.  

PubMed

It has been argued extensively that diagnostic services are a general good, but that it is offered in excess. So what is the problem? Is not "too much of a good thing wonderful", to paraphrase Mae West? This article explores such a possibility in the field of radiological services where it is argued that more than 40% of the examinations are excessive. The question of whether radiological examinations are excessive cries for a definition of diagnostic futility. However, no such definition is found in the literature. As a response, this article addresses the issue of diagnostic futility in five steps. First, it investigates whether the concept of therapeutic futility can be adapted to diagnostics. A closer analysis of the concept of therapeutic futility reveals that this will not do the trick. Second, the article scrutinizes whether there are sources for clarifying diagnostic futility in the extensive debate on excessive radiological examination. Investigating the debate's terms and definitions reveals a disparate terminology and no clear concepts. On the contrary, the study uncovers that quite different and incompatible issues are at stake. Third, the article examines a procedural approach, which is widely used for settling controversies over utility by focusing on the role of the professionals. On scrutiny however, a procedural approach will not solve the problem in diagnostics. Fourth, a value analysis reveals how we have to decide on the negative value of excessive examinations before we can measure excess. The final and constructive part presents a definition of diagnostic futility drawing upon the lessons from the previous analytical steps. Altogether, too much radiological examination is not a good thing. This is simply because radiological examinations are not unanimously good. Excessive radiological examinations can be defined, but not by one simple general and value-neutral definition. We have to settle with contextually framed value-related definitions. Such definitions will state how bad "too much of a good thing" is and make it possible to assess how much of the bad thing there is. Hence we have to know how bad it is before we can tell how much of it there is in the world. PMID:20151206

Robotic master-slave devices can assist surgeons to perform minimally invasive esophageal operations with approaches that have already been demonstrated using laparoscopy and thoracoscopy. Robotic-assisted surgery for benign esophageal disease is described for the treatment of achalasia, epiphrenic diverticula, refractory reflux, paraesophageal hernias, duplication cysts, and benign esophageal masses, such as leiomyomas. Indications and contraindications for robotic surgery in benign esophageal disease should closely approximate the indications for laparoscopic and thoracoscopic procedures. Given the early application of the technology and paucity of clinical evidence, there are currently no procedures for which robotic esophageal surgery is the clinically proven preferred approach.

Diagnostics in the Extendable Integrated Support Environment (EISE)  

NASA Technical Reports Server (NTRS)

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.

[Arthroscopy of the elbow: diagnostic and therapeutic approaches].  

PubMed

The elbow is one of the most complex joints of the human body. Bony, ligamentous and muscular constraints ensure elbow stability. During recent years elbow arthroscopy has become more and more popular resulting from technical and surgical innovations. The diagnostic and therapeutic elbow arthroscopy following traumatic elbow dislocation is the best example. Functional outcomes after elbow dislocation significantly depend on sufficient evaluation of elbow stability, possible accompanying soft tissue injuries and on the initiation of adequate therapy. Elbow arthroscopy after traumatic elbow dislocation allows visualization of ligament ruptures and cartilaginous lesions, the resection of loose bodies and flushing of the hemarthrosis. Moreover, elbow stability can be tested directly. Concerning therapy, elbow arthroscopy represents an additional diagnostic tool and an aid for possible surgical procedures. In this article the basic requirements and special techniques for elbow arthroscopy are described. Using the examples of an elbow dislocation and arthrofibrosis, arthroscopical standard views, arthroscopical stability test and arthroscopical arthrolysis are explained. PMID:25245986

Salivary Biomarkers: Toward Future Clinical and Diagnostic Utilities  

PubMed Central

SUMMARY 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.

Rapid mass spectrometric DNA diagnostics for assessing microbial community activity during bioremediation. 1997 annual progress report  

SciTech Connect

'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).'

[New molecular methods in prenatal invasive diagnostics].  

PubMed

New diagnostic techniques employed in laboratories all over the world enable to create new tests for prenatal genetic diagnosis. They include cytogenetics, molecular-cytogenetics and molecular methods. Chromosomal numerical aberrations (aneuploidies) remain to be the most frequent genetic changes diagnosed prenatally Therefore, our paper presents the latest methods used mainly in prenatal diagnosis of the most common chromosome numerical changes, as well as other methods applicable in detecting chromosome structural changes or gene mutations. One of the main advantages of these new approaches is the short period of time needed to obtain a result. Some of these techniques are used world-wide: QF-PCR (Fluorescence Quantitive Polymerase Chain Reaction)--based on the analysis of the short polymorphic sequences characteristic for each individual; MLPA (Multiplex Ligation-dependent Probe Amplification)--based on the probes ligation to complementary genomic fragments in patient DNA; microarray CGH (Comparative Genomic Hybridization)--based on genomic hybridization to microarray, which enables analysis of the entire genome. Other new methods are also gradually introduced to invasive prenatal diagnosis: NGS (Next-generation DNA sequencing)--for the analysis of the whole genome at the DNA level; BoBs (BACS-on-Beads)--molecular-cytogenetic technique based on hybridization of probes immobilized on polystyrene microspheres with fetal DNA. Nowadays, rapid diagnosis of the most common chromosomal aneuploidies is not a standard procedure in Poland, as opposed to cytogenetics (karyotyping). However, for specific clinical indications, fast and reliable methods of genetic analysis present are likely to become standard procedures in prenatal diagnosis. PMID:24273910

Molecular Diagnostic Tests for Microsporidia  

PubMed Central

The Microsporidia are a ubiquitous group of eukaryotic obligate intracellular parasites which were recognized over 100 years ago with the description of Nosema bombycis, a parasite of silkworms. It is now appreciated that these organisms are related to the Fungi. Microsporidia infect all major animal groups most often as gastrointestinal pathogens; however they have been reported from every tissue and organ, and their spores are common in environmental sources such as ditch water. Several different genera of these organisms infect humans, but the majority of infections are due to either Enterocytozoon bieneusi or Encephalitozoon species. These pathogens can be difficult to diagnose, but significant progress has been made in the last decade in the development of molecular diagnostic reagents for these organisms. This report reviews the molecular diagnostic tests that have been described for the identification of the microsporidia that infect humans. PMID:19657457

Sequencing needs for viral diagnostics.  

PubMed

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. Severe acute respiratory syndrome 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.

Diagnostics for Fast Ignition Science  

SciTech Connect

The concept for Electron Fast Ignition Inertial Confinement Fusion demands sufficient laser energy be transferred from the ignitor pulse to the assembled fuel core via {approx}MeV electrons. We have assembled a suite of diagnostics to characterize such transfer. Recent experiments have simultaneously fielded absolutely calibrated extreme ultraviolet multilayer imagers at 68 and 256eV; spherically bent crystal imagers at 4 and 8keV; multi-keV crystal spectrometers; MeV x-ray bremmstrahlung and electron and proton spectrometers (along the same line of sight); nuclear activation samples and a picosecond optical probe based interferometer. These diagnostics allow careful measurement of energy transport and deposition during and following laser-plasma interactions at extremely high intensities in both planar and conical targets. Augmented with accurate on-shot laser focal spot and pre-pulse characterization, these measurements are yielding new insight into energy coupling and are providing critical data for validating numerical PIC and hybrid PIC simulation codes in an area that is crucial for many applications, particularly fast ignition. Novel aspects of these diagnostics and how they are combined to extract quantitative data on ultra high intensity laser plasma interactions are discussed, together with implications for full-scale fast ignition experiments.

The Direct Boil-LAMP method: a simple and rapid diagnostic method for cutaneous leishmaniasis.  

PubMed

Needle biopsy is widely used for the diagnosis of cutaneous leishmaniasis (CL) to obtain specimens for histology and culture. However, the use of such invasive procedures causes discomfort, requires technical expertise, and carries risks of bleeding and iatrogenic infection. Therefore, developing substitutive non-invasive diagnostic tools for CL will help reduce the risk of secondary infection and the exposure of both infected individuals and medical professionals. Here we employed loop-mediated isothermal amplification and boiled swab samples (Direct Boil-LAMP method) from CL model mice to develop a simple and rapid diagnostic method for CL. The detection limit of this procedure was 1.0×10(3)parasites/mL. Accordingly, this substitutive diagnostic method should prove useful for mass screening. In addition, we discuss the potential advantages of using it, particularly in endemic regions where medical resources are limited. PMID:25086375

Summary from working group on noninterceptive diagnostics  

SciTech Connect

The working group for noninterceptive diagnostics spent much of its time comparing diagnostic techniques from different fields and their possible application to high-power injectors. The group included backgrounds from electron beam diagnostics, fusion power diagnostics, cw ion source and transport design, and ion beam of diagnostics. The probability of success for adapting techniques from these different areas is quite difficult to judge, short of a detailed examination of each application. Unexpected flaws or unforeseen noise sources can eliminate an idea that would otherwise appear promising. The report presents several ideas that were discussed, with an indication of those ideas most likely to succeed if implemented.

Mammary Epithelial Transplant Procedure  

PubMed Central

This article describes and compares the fat pad clearance procedure developed by DeOme KB et al.1 and the sparing procedure developed by Brill B et al.2, followed by the mammary epithelial transplant procedure. The mammary transplant procedure is widely used by mammary biologists because it takes advantage of the fact that significant development of the mammary epithelium doesn't occur until after puberty. At 3 weeks of age, growth of the mammary epithelial tree is confined to the vicinity of the nipple and the fat pad is largely devoid of mammary epithelium, but by 7 weeks of age the epithelial ductal tree extends throughout the entire fat pad. Therefore, if this small portion of the fat pad containing epithelium, the region between the nipple and the lymph node, is removed at 3 weeks of age, the endogenous epithelium will never populate the mammary fat pad and the fat pad is described as "cleared". At this time, mammary epithelium from another source can be transplanted in the cleared fat pad where it has the potential to extend mammary ductal trees through out the fat pad. This procedure has been utilized in many experimental models including the examination of tumor phenotype in transgenic mammary epithelial tissue without the confounding effects of genotype on the entire animal3, in the identification of mammary stem cells by transplanting cells in limited dilution4,5, determining if hyperplastic nodules proceed to mammary tumors6, and to assess the effect of prior hormone exposure on the behavior of the mammary epithelium7,8. Three week old host mice are anesthetized, cleaned and restrained on a surgical stage. A mid-sagittal incision is made through the skin, but not the peritoneum, extending from the pubis to the sternum. Oblique cuts are made through the skin from the mid-sagittal incision across the pelvis toward each leg. The skin is pulled away from the peritoneum to expose the 4th inguinal mammary gland. The fat pad is cleared by removing the fat pad tissue anterior to the lymph node. Epithelium fragments or epithelial cells are transplanted into the remaining cleared fat pad and the mouse is closed.

Ingestible wireless capsules for enhanced diagnostic inspection of gastrointestinal tract  

NASA Astrophysics Data System (ADS)

Wireless capsule endoscopy has become a common procedure for diagnostic inspection of gastrointestinal tract. This method offers a less-invasive alternative to traditional endoscopy by eliminating uncomfortable procedures of the traditional endoscopy. Moreover, it provides the opportunity for exploring inaccessible areas of the small intestine. Current capsule endoscopes, however, move by peristalsis and are not capable of detailed and on-demand inspection of desired locations. Here, we propose and develop two wireless endoscopes with maneuverable vision systems to enhance diagnosis of gastrointestinal disorders. The vision systems in these capsules are equipped with mechanical actuators to adjust the position of the camera. This may help to cover larger areas of the digestive tract and investigate desired locations. The preliminary experimental results showed that the developed platform could successfully communicate with the external control unit via human body and adjust the position of camera to limited degrees.

The essence on mass spectrometry based microbial diagnostics.  

PubMed

In recent years, matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) mass spectrometry has become an important bioanalytical method to detect profiles of proteins and peptides derived from whole bacterial cells. This accurate molecular-phenotypic method can be easily applied to robustly detect bacteria on the genus, species and in some cases on the subspecies level. Standardised laboratory protocols for the preparation of abundant bacterial proteins and the development of tailored data analysis software, as well as high-quality databases of microbial reference mass spectra, made the procedure attractive to replace phenotypic or biochemical procedures for identification of bacteria and other microorganisms. Moreover, genotypic and functional mass spectrometry based methods to detect for example bacterial strains or antibiotic resistance may become useful in the coming years. In general, mass spectrometry is a powerful tool to facilitate routine microbial diagnostics. PMID:22410108

Infrared diagnostics of interstellar shocks  

NASA Technical Reports Server (NTRS)

The observations and theoretical models concerning interstellar shock waves are discussed. Interstellar shock waves are generated by the supersonic injection of mass into the interstellar medium by young stellar objects, by stellar winds, and by supernovae. Infrared emission lines from the heated, shocked gas provide valuable diagnostics of the density, temperature, velocity field, elemental abundances and extent of the emitting region. It is shown that the comparison of observed spectra from shocked regions with theoretical shock models can provide an estimate of the shock speed and the physical conditions in the preshock gas, including the ionization fraction and the magnetic field strength.

[Pedophilia. Prevalence, etiology, and diagnostics].  

PubMed

Pedophilia is a disorder of sexual preference that increases the risk for committing sexual offenses against children. Consequently, pedophilia is not only relevant in psychiatric therapy and prognostics, but also greatly influences the public attitude towards criminality. Public opinion seems to equate pedophilia with child sexual abuse and vice versa which leads to stigmatization of patients and may impede treatment. The present paper provides information on recent studies on the potential origins of the disorder and introduces new diagnostic methods. Moreover, the article presents estimates on the prevalence of pedophilic sexual interest. PMID:21909808

Obturator hernia: a diagnostic challenge.  

PubMed

We describe a case of an 82-year-old lady with groin pain secondary to an obturator hernia. She was a diagnostic challenge, and 6 years passed before the obturator hernia was discovered. She presented to hospital with symptoms of bowel obstruction, and a computer tomography (CT) scan of her pelvis revealed an incarcerated obturator hernia. Her surgical management included reinforcement of the obturator foramen with sutures. A recurrence of the obturator hernia 2 years later required an extra-peritoneal mesh repair of the defect in the obturator foramen with a good outcome. PMID:18636223

Pipe Cleaning Operating Procedures  

SciTech Connect

This cleaning procedure outlines the steps involved in cleaning the high purity argon lines associated with the DO calorimeters. The procedure is broken down into 7 cycles: system setup, initial flush, wash, first rinse, second rinse, final rinse and drying. The system setup involves preparing the pump cart, line to be cleaned, distilled water, and interconnecting hoses and fittings. The initial flush is an off-line flush of the pump cart and its plumbing in order to preclude contaminating the line. The wash cycle circulates the detergent solution (Micro) at 180 degrees Fahrenheit through the line to be cleaned. The first rinse is then intended to rid the line of the majority of detergent and only needs to run for 30 minutes and at ambient temperature. The second rinse (if necessary) should eliminate the remaining soap residue. The final rinse is then intended to be a check that there is no remaining soap or other foreign particles in the line, particularly metal 'chips.' The final rinse should be run at 180 degrees Fahrenheit for at least 90 minutes. The filters should be changed after each cycle, paying particular attention to the wash cycle and the final rinse cycle return filters. These filters, which should be bagged and labeled, prove that the pipeline is clean. Only distilled water should be used for all cycles, especially rinsing. The level in the tank need not be excessive, merely enough to cover the heater float switch. The final rinse, however, may require a full 50 gallons. Note that most of the details of the procedure are included in the initial flush description. This section should be referred to if problems arise in the wash or rinse cycles.

Surface cleanliness measurement procedure  

DOEpatents

A procedure and tools for quantifying surface cleanliness are described. Cleanliness of a target surface is quantified by wiping a prescribed area of the surface with a flexible, bright white cloth swatch, preferably mounted on a special tool. The cloth picks up a substantial amount of any particulate surface contamination. The amount of contamination is determined by measuring the reflectivity loss of the cloth before and after wiping on the contaminated system and comparing that loss to a previous calibration with similar contamination. In the alternative, a visual comparison of the contaminated cloth to a contamination key provides an indication of the surface cleanliness.

Integrated Diagnostic Analysis of ICF Capsule Performance  

NASA Astrophysics Data System (ADS)

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.

Some results of multiwave in situ autofluorescence diagnostics  

NASA Astrophysics Data System (ADS)

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.
