Abductive Reasoning with Uncertainty  

Microsoft Academic Search

Abductive reasoning in general de- scribes the process of discovering hy- potheses and rules that would entail a given conclusion. Abductive reason- ing consists of assessing the likelihood that a specific hypothesis entails a given conclusion. Abductive reasoning based on probabilities is used in many dis- ciplines, such as medical diagnostics, where medical test results combined with conditional probabilities are

Astigmatism and diagnostic procedures.  

PubMed

Astigmatism represents an inability of the cornea and lens to provide a sharp image onto the retina. Correcting astigmatic errors, whether congenital, contact lens induced or surgically induced, is now an integral part of modern cataract and refractive procedures. Development of modern technology has enabled accurate diagnosis and perfect opportunities for correction; however, while cataract and keratorefractive surgery have come a long way in the last decade, the treatment and diagnosis of astigmatism continue to challenge ophthalmologists. There are several diagnostic procedures and tools available today, some standard and some contemporary that include keratometry, corneal topography, apparatus using wavefront or Scheimpflug analysis like Orbscan, Pentacam, Wavescan, etc. With the introduction of several new diagnostic tools, measurements of astigmatism have become less of an issue, but in some cases it is still difficult to obtain consistent results. What remains still unanswered is the question of the best diagnostic tool on the market. Further research is needed to evaluate both tools as well as their clinical application for optimal use.

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.

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.

[Catastrophes caused by neurologic diagnostic procedures].  

PubMed

Serious complications (catastrophes) resulting from diverse neurological diagnostic procedures can be caused by erroneous indication and omission, as well as by delay and erroneous execution or interpretation. Headache, caused by cerebrospinal fluid (CSF) hypotension, is a frequent complication of lumbar puncture; hematic patch is a therapeutic option for severe cases. The most serious complication is cerebral herniation and, for its prevention, computed tomography (CT) or cerebral magnetic resonance imaging (MRI) must always be performed before lumbar puncture: a lesion with evident mass effect is a contraindication. Some cases of minor subarachnoid hemorrhages can produce sentinel headache: when the findings of CT scans are normal, lumbar puncture must be performed for diagnosis and prevention of a catastrophic recurrence. Edrophonium testing can be complicated with bradycardia and/or asystole. The lack of indication of this procedure is a cause of under-diagnosis of myasthenia gravis, especially in older people. Electromyography produces few complications (rare cases of paraspinal hematomas and pneumothorax). Ultrasound, CT angiography and MR angiography examinations have decreased the indications for cerebral angiography, whose main complications -in addition to contrast reactions, hemorrhage and infection at the injection site- are neurological deficits caused by vascular dissection or atheromatous embolus. Video-electroencephalogram (EEG) recording with medication suppression can be used in the presurgical evaluation of epilepsy, which can precipitate repeated seizures with the risk of injuries and status epilepticus. The possible complications of studies performed with invasive electrodes are infections and intracranial hemorrhages. Cerebral biopsy is indicated when treatable disease is suspected but the therapeutic options (radiotherapy, chemotherapy) have potential serious adverse effects. Furthermore, cerebral biopsy can aggravate previous neurological deficits or produce new deficits. Genetic testing is not indicated in healthy children when an untreatable disease is suspected. In adults, genetic testing is appropriate in selected cases, but detailed previous information should be gathered and the possibility of triggering serious emotional reactions should always be considered.

Cancer Risks Associated with External Radiation From Diagnostic Imaging Procedures  

PubMed Central

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

Diagnostic imaging procedure volume in the United States  

SciTech Connect

Comprehensive data on 1979 and 1980 diagnostic imaging procedure volume were collected from a stratified random sample of U.S. short-term general-care hospitals and private practices of radiologists, cardiologists, obstetricians/gynecologists, orthopedic surgeons, and neurologists/neurosurgeons. Approximately 181 million imaging procedures (within the study scope) were performed in 1980. Despite the rapidly increasing use of newer imaging methods, plain film radiography (140.3 million procedures) and contrast studies (22.9 million procedures) continue to comprise the vast majority of diagnostic imaging volume. Ultrasound, computed tomography, nuclear medicine, and special procedures make up less than 10% of total diagnostic imaging procedures. Comparison of the data from this study with data from an earlier study indicates that imaging procedure volume in hospitals expanded at an annual growth rate of almost 8% from 1973 to 1980.

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 in autism spectrum disorders: a systematic literature review.  

PubMed

At present, 'gold standard' diagnosis of autism spectrum disorders (ASD) is a lengthy and time consuming process that requires suitably qualified multi-disciplinary team (MDT) personnel to assess behavioural, historical, and parent-report information to determine a diagnosis. A number of different tools have been developed to assist in determination. To optimise the diagnostic procedures, the best diagnostic instruments need to be identified. This study is a systematic review addressing the accuracy, reliability, validity and utility of reported diagnostic tools and assessments. To be included in this review, studies must have (1) identified an ASD diagnostic tool; (2) investigated either diagnostic procedure or the tools or personnel required; (3) be presented in English; (4) be conducted in the Western world; (5) be one of three types of studies [adapted from Samtani et al. in Cochrane Database Syst Rev 3:1-13, 2011], viz. (a) cohort studies or cross-sectional studies, (b) randomised studies of test accuracy, (c) case-control studies. MEDLINE, PsychINFO, Scopus, EMBASE, and Cochrane Library databases were scrutinised for relevant literature published from 2000 inclusive on 20th January 2012. In total, 68 articles were included. 17 tools were assessed. However, many lacked an evidence base of high quality-independent studies. The Autism Diagnostic Interview-Revised (ADI-R) and Autism Diagnostic Observation Schedule (ADOS) stood out with the largest evidence base and highest sensitivity and specificity. When the ADI-R and ADOS were used in combination they revealed levels of accuracy very similar to the correct classification rates for the current 'gold standard' diagnostic procedure viz. 80.8% for ASD. There is scope for future studies on the use of the ADI-R and ADOS in combination. PMID:23322184

[Ophthalmologic diagnostic procedures and imaging of retinal vein occlusions].  

PubMed

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

False allegation of child abduction.  

PubMed

Cases in which a child has been falsely reported as missing or abducted can be extremely challenging to the law enforcement agencies responsible for their investigation. In the absence of a witnessed abduction or an obvious crime scene, it is difficult to determine whether a child has actually been abducted or has become a victim of a homicide and a false allegation. The purpose of this study was to examine falsely alleged kidnapping cases and identify successful investigative strategies. Sixty-one adjudicated false allegation cases involving 66 victims were analyzed. The mean age of the victim was 5 years. Victims came from generally unstable, high-risk family situations and were killed primarily by biological parents. Victims were killed because they were unwanted or viewed as an obstacle to a desired goal, or they were victims of abuse or maltreatment that ended in fatality. PMID:21361941

Prenatal diagnosis--principles of diagnostic procedures and genetic counseling.  

PubMed

The frequency of inherited malformations as well as genetic disorders in newborns account for around 3-5%. These frequency is much higher in early stages of pregnancy, because serious malformations and genetic disorders usually lead to spontaneous abortion. Prenatal diagnosis allowed identification of malformations and/or some genetic syndromes in fetuses during the first trimester of pregnancy. Thereafter, taking into account the severity of the disorders the decision should be taken in regard of subsequent course of the pregnancy taking into account a possibilities of treatment, parent's acceptation of a handicapped child but also, in some cases the possibility of termination of the pregnancy. In prenatal testing, both screening and diagnostic procedures are included. Screening procedures such as first and second trimester biochemical and/or ultrasound screening, first trimester combined ultrasound/biochemical screening and integrated screening should be widely offered to pregnant women. However, interpretation of screening results requires awareness of both sensitivity and predictive value of these procedures. In prenatal diagnosis ultrasound/MRI searching as well as genetic procedures are offered to pregnant women. A variety of approaches for genetic prenatal analyses are now available, including preimplantation diagnosis, chorion villi sampling, amniocentesis, fetal blood sampling as well as promising experimental procedures (e.g. fetal cell and DNA isolation from maternal blood). An incredible progress in genetic methods opened new possibilities for valuable genetic diagnosis. Although karyotyping is widely accepted as golden standard, the discussion is ongoing throughout Europe concerning shifting to new genetic techniques which allow obtaining rapid results in prenatal diagnosis of aneuploidy (e.g. RAPID-FISH, MLPA, quantitative PCR).

[Guidelines of initial diagnostic procedures for bacterial infectious disease].  

PubMed

The practice of the initial diagnostic procedures for infectious disease in febrile patients is important. The rational screening steps to the correct diagnosis of infections are: 1) thorough history taking and physical examination (identification of the organs affected), 2) simpler essential laboratory tests such as white blood cell count, microscopy of blood smear, determination of C-reactive protein, electrocardiography and chest x-ray film (confirmation of infection), 3) direct or indirect demonstration of pathogenic organisms by stain-enhanced microscopy and culture of specific specimens (identification of etiologic organisms). Extensive culture and serologic testing on febrile patients for identification of organisms depend on individual basis. Indeed, medical care is a team effort with collaboration of doctors, nurses and technologists. More importantly the doctor in charge is fully responsible for interrogation and examination of the patients, interpretation of laboratory results, diagnoses and treatments. PMID:2199699

Prevention of tumour cell dissemination in diagnostic needle procedures  

PubMed Central

Background: A side effect of diagnostic needle biopsies is the possibility to disseminate tumour cells into the needle track, which may cause concern in certain malignant tumour types. Methods: In order to prevent tumour cell dissemination we developed a technology that uses radiofrequency (RF) pulses to sterilise the needle track and denaturate tumour cells. To determine feasibility, we applied this technology to fine needle aspiration biopsy (FNAB) and used breast cancer as a model tumour. Routine FNAB was performed in 88 patients with adenocarcinoma and blood droplets passing the skin orifice were cytomorphologically analysed for the presence of tumour cells. Results: The analysis showed the presence of tumour cells in 65/88 cases (74%). When using an experimental anti-seeding device in a subset of patients viable tumour cells were found in 0/31 cases (P<0.001). In all 31 patients blood passing the skin orifice was sparse. No degrading effect on the cytological sample inside the needle was detected and pain caused by the RF pulses was comparable to that of the biopsy procedure itself. Conclusion: The herein presented method has the potential to prevent the dissemination of viable tumour cells in the needle track and minimize bleeding without additional pain or degradation of the aspirate.

Implication of Abduction: Complexity without Organized Interaction  

NASA Astrophysics Data System (ADS)

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

[Influence of dry eye syndrome on glaucoma diagnostic procedures].  

PubMed

Approximately 50-60% of primary open angle glaucoma patients suffer from dry eye and ocular surface disease and have a reduced corneal thickness. The measurements by imaging procedures are weakened by signal noise and perimetry procedures are affected by generalized loss of sensitivity. In dry eye patients, possible influences on new perimetry procedures, such as frequency doubling technology (FDT), flicker-defined form (FDF) perimetry and pulsar perimetry (PP) potentially result from stray light and reduced contrast sensitivity. In glaucoma patients with ocular surface disturbances, measuring procedures with high sensitivity and low specificity should be carefully checked for plausibility by the examiner. Using these procedures uncritically involves the danger of over interpretation in terms of non-existent glaucoma progression. If necessary, eyes should be pretreated with lubricating eye drops or therapy should be switched to preservative-free pressure lowering drops. Afterwards, new control measurements should be taken to exclude glaucoma pseudoprogression. PMID:23179813

Kinematic mental simulations in abduction and deduction.  

PubMed

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.

Antiplatelet action of intravascular contrast media. Implications in diagnostic procedures.  

PubMed

The antiplatelet action of intravascular contrast media (CM) Renografin-76 (diatrizoate meglumine and diatrizoate sodium) was studied in vitro and in 21 patients undergoing radiodiagnostic procedures. In vitro studies suggested that in Renografin-76, meglumine was the chief constituent responsible for its antiplatelet action. In post-CM plasma from patients, clotting times were prolonged and platelet aggregation greatly impaired, albeit normal aggregation restored within 3 hours. Although changes in global clotting times and platelet aggregation were mostly transient, it is possible that CM usage in patients with thrombocytopenia, sickle cell phenomenon, and on anticoagulant-antiplatelet drugs may present a serious risk to their hemostatic integrity.

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.

Clinical experiences with emergency ultrasound guided diagnostic and therapeutic procedures in a department of internal medicine.  

PubMed

In some particular clinical emergencies, it is mandatory to obtain a pathological diagnosis as soon as possible and to start therapy quickly. This can be often done by means of ultrasound guided fine needle biopsy. The cases of emergency ultrasound guided fine needle biopsies and drainages performed in our Ultrasound Laboratory over the past 5 years represent 1.6% of all procedures performed on deeply located lesions. Diagnostic accuracy of emergency ultrasound guided fine needle biopsies was comparable to that obtained in routine situations. In 11/12 patients, this diagnostic procedure allowed the immediate start of proper therapy. Emergency ultrasound guided percutaneous drainage was performed in 6 patients and all of them had a successful outcome. We conclude that emergency ultrasound guided diagnostic and therapeutic procedures, although rarely necessary, can be very useful in some clinical situations. The high efficacy of these techniques is not impaired in an emergency. PMID:10399368

Activities identification for activity-based cost/management applications of the diagnostics outpatient procedures.  

PubMed

One of the most challenging problems facing healthcare providers is to determine the actual cost for their procedures, which is important for internal accounting and price justification to insurers. The objective of this paper is to find suitable categories to identify the diagnostic outpatient medical procedures and translate them from functional orientation to process orientation. A hierarchal task tree is developed based on a classification schema of procedural activities. Each procedure is seen as a process consisting of a number of activities. This makes a powerful foundation for activity-based cost/management implementation and provides enough information to discover the value-added and non-value-added activities that assist in process improvement and eventually may lead to cost reduction. Work measurement techniques are used to identify the standard time of each activity at the lowest level of the task tree. A real case study at a private hospital is presented to demonstrate the proposed methodology. PMID:22059478

Infant hospital abduction: security measures to aid in prevention.  

PubMed

The purpose of this article is to describe measures used to prevent abduction of infants from healthcare facilities. According to the National Center for Missing & Exploited Children, 122 infants were abducted from hospitals between 1983 and 2008; characteristics of the abductors have been found to be similar in the majority of infant abductions. The Joint Commission has established security standards, and conducts assessments to identify abduction risk within hospitals. Nurses can contribute to the safety and security of infants by following prevention plans which emphasize these and other actions: educating parents about abduction risks, using identically numbered bands on the baby and parents, taking color photographs of the infant, wearing color photograph ID badges themselves, discouraging parents/families from publishing birth notices in the public media, controlling access to nursery/postpartum unit, and utilizing infant security tags or abduction alarm systems.

Diagnostic procedure on brake pad assembly based on Young's modulus estimation  

NASA Astrophysics Data System (ADS)

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

Extensor digiti minimi tendon "rerouting" transfer in permanent abduction of the little finger.  

PubMed

Permanent abduction of the little finger is a bothersome deformity which usually occurs in the context of sequelae of ulnar nerve palsy (Wartenberg's sign), but also in rheumatoid arthritis. The authors report an original technique for correction of this deformity. The extensor digiti minimi tendon is sectioned at its distal insertion and transferred in the wrist through the extensor retinaculum. The "rerouted" tendon is finally resutured distally on the radial aspect of the interosseous muscle. Side-to-side suture of the transferred tendon to the extensor digitorum tendon of the little finger further reinforces the solidity of the procedure. The distal insertion of the extensor digiti minimi tendon is consequently radialized. Its new direction eliminates the abduction component, and the tendon then behaves as an active adductor of the little finger. Five cases (2 cases of ulnar nerve palsy, 3 cases of rheumatoid arthritis) are reported with a mean follow-up of 19 months. All patients have complete active adduction of the little finger in extension, with a persistent capacity for abduction. The other correction techniques published in the literature are discussed.

Intercultural caring-an abductive model.  

PubMed

The aim of this study was to increase the understanding of caring from a transcultural perspective and to develop the first outline of a theory. The theoretical perspective includes Eriksson's theory of caritative caring. Texts on caring by the transcultural theorists, including Campinha-Bacote, Kim-Godwin, Leininger and Ray, are analysed using content analysis. The overall theme that resulted from this analysis was that caring is a complex whole. Three main categories of caring emerged: inner caring, outer caring and the goal of caring. Inner caring consists of caring is a relationship, and caring and culture are seen in different dimensions. Outer caring refers to caring affected by educational, administrative and social and other structures. The goal of caring consists of caring leading to change towards health and well-being. The main categories include categories and subcategories that are compared with Eriksson's theory of caritative caring. A model for intercultural caring is generated abductively. Caring and culture appear in three dimensions: caring as ontology independent of context; caring as a phenomenon emphasised differently in different cultures; caring as nursing care activities is unique. Caring alleviates suffering and leads to health and well-being. This model describes caring from an intercultural perspective as a mutual but asymmetric relationship between the nurse and the patient, including the patient's family and community. The patient's cultural background and acculturation influence caring. The cultural background, cultural competence and organisation of the nurse also influence caring. Caring is seen as a complex whole. This study integrates Campinha-Bacote's, Kim-Godwin's, Leininger's and Ray's views of caring with Eriksson's caritative caring and presents caring from a transcultural perspective in a new way as a model for intercultural caring, which can benefit nursing care, education, research and administration.

Child abduction murder: the impact of forensic evidence on solvability.  

PubMed

This study examined 733 child abduction murders (CAMs) occurring from 1968 to 2002 to explore the influence of forensic evidence on case solvability in CAM investigations. It was hypothesized that the presence of forensic evidence connecting the offender to the crime would enhance case solvability in murder investigations of abducted children. This study examined the impact of CAM of different types of forensic evidence and the impact of the summed total of forensic evidence items on case solvability by controlling for victim age, victim race, victim gender, and victim-offender relationship. Time and distance theoretical predictors were also included. Binomial logistic regression models were used to determine whether forensic evidence was a critical solvability factor in murder investigations of abducted children. This research indicated that, while forensic evidence increased case solvability, the impact of forensic evidence on solvability was not as important as other solvability factors examined.

Electrophysiological testing of masseter and blink reflexes indicated an ipsilateral rostral pontine or mesencephalic lesion, and excluded a lesion of the infranuclear portion of the abducens nerve. Abduction paresis was attributed to impaired inhibition of the tonic resting activity of the antagonistic medial rectus muscle. The prenuclear origin of the disorder is based on morphological and neurophysiological evidence of an ipsilateral inhibitory connection between the paramedian pontine reticular formation and the oculomotor nucleus running close to but separated from the medial longitudinal fasciculus.

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

IDH1 mutation analysis in low cellularity specimen: a limitation of diagnostic accuracy and a proposal for the diagnostic procedure.  

PubMed

Recently, new techniques for detecting IDH1 mutations have been developed. Most studies assessed the mutation status in glioma tissue without consideration of the size of the samples. We assessed the mutation status of IDH1 in simulated small biopsied tissue from 5 low grade gliomas, prepared by grid cutting procedure with direct sequencing, IDH1 immunohistochemistry (IHC), multiplex PCR with single base extension (SBE) assay and PNA-clamping method, and then analyzed the agreement between the methods. Kappa values were 0.53 (direct sequencing), 0.59 (multiplex PCR with SBE assay), and 0.69 (PNA-clamping method). Discrepant results between the methods were observed in lower cellularity samples. Twelve out of 25 cases were classified as wild type by direct sequencing, even with IDH1 IHC-positive cells, whereas 6, 8, and 11 of IHC-negative cases were classified as mutant cases by other 3 methods. In conclusion, newly developed sensitive methods, such as the PNA-clamping method and multiplex PCR with SBE assay, are practically useful in addition to the conventional IDH1 IHC in small biopsied samples.

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.

PubMed

3000 sonographic examinations of the liver were performed. The results of 142 sonographic studies were compared with the findings obtained by subsequent laparoscopy and microscopy. In 90% there was good agreement between the sonographic diagnosis and the microscopic findings. Fatty liver (97%) and metastasis (95%) into the liver were diagnosed accurately. 3 hematomas of the liver were found in 150 patients who underwent liver biopsy. Sonographic examination of the liver is usefull in: (1) determining topographic anatomy of the liver before needle biopsy. (2) deciding the next diagnostic step within the catalogue of indications for the morphologic diagnosis of the liver given by the IASL. Ultrasound shortens diagnosis.

4D laser camera for accurate patient positioning, collision avoidance, image fusion and adaptive approaches during diagnostic and therapeutic procedures.  

PubMed

A four-dimensional (4D) laser camera (LC) has been developed for accurate patient imaging in diagnostic and therapeutic radiology. A complementary metal-oxide semiconductor camera images the intersection of a scanned fan shaped laser beam with the surface of the patient and allows real time recording of movements in a three-dimensional (3D) or four-dimensional (4D) format (3D +time). The LC system was first designed as an accurate patient setup tool during diagnostic and therapeutic applications but was found to be of much wider applicability as a general 4D photon "tag" for the surface of the patient in different clinical procedures. It is presently used as a 3D or 4D optical benchmark or tag for accurate delineation of the patient surface as demonstrated for patient auto setup, breathing and heart motion detection. Furthermore, its future potential applications in gating, adaptive therapy, 3D or 4D image fusion between most imaging modalities and image processing are discussed. It is shown that the LC system has a geometrical resolution of about 0, 1 mm and that the rigid body repositioning accuracy is about 0, 5 mm below 20 mm displacements, 1 mm below 40 mm and better than 2 mm at 70 mm. This indicates a slight need for repeated repositioning when the initial error is larger than about 50 mm. The positioning accuracy with standard patient setup procedures for prostate cancer at Karolinska was found to be about 5-6 mm when independently measured using the LC system. The system was found valuable for positron emission tomography-computed tomography (PET-CT) in vivo tumor and dose delivery imaging where it potentially may allow effective correction for breathing artifacts in 4D PET-CT and image fusion with lymph node atlases for accurate target volume definition in oncology. With a LC system in all imaging and radiation therapy rooms, auto setup during repeated diagnostic and therapeutic procedures may save around 5 min per session, increase accuracy and allow efficient image fusion between all imaging modalities employed.

[New diagnostic methods--ultrasound and clinico-chemical procedures in diagnosis of ischemia].  

PubMed

Stress-echocardiography represents a new non-invasive, alternative approach in the assessment of patients with coronary artery disease. By means of dynamic or pharmacological stress or by atrial pacing regional wall motion abnormalities can be induced, which can be identified by 2D-echocardiography. Beyond the indirect detection of ischemia this approach allows a better quantification of the amount of ischemia and of global LV function, which is advantageous compared to stress ECG recording or myocardial scintigraphy. Disadvantageous is however, the subjective reading of the echo itself. In experienced hands stress-echocardiography has proven to be as sensitive and specific as myocardial scintigraphy. Recently, in addition the diagnostic potential of myocardial cell injury has been improved by the detection of specific antibodies versus Troponin T. In comparison with conventional biochemical markers of myocardial cell necrosis Troponin T analysis has been proven to be superior in postoperative or traumatic cardiac damage or in the setting of acute myocardial infarction. In this situation the time window is improved by an earlier rise compared to CK and a longer detection rate compared to lactate dehydrogenase. PMID:8154150

Efficacy of clinical diagnostic procedures utilized in nuclear medicine. Technical progress report, 1 December 1981-30 November 1982  

SciTech Connect

The efficacy of nuclear medicine diagnostic procedures was measured. Three levels of efficacy were defined. However, two different methods of evaluating efficacy itself were first compared. Using two methods, logistic regression and entropy-minimax pattern detection, substantial agreement was found between them in several clinical observations. (1) There are no attributes that indicate that any grouping of symptoms, signs, and laboratory findings is capable of suggesting that a patient does or does not have a pulmonary embolus. (2) The lung scan test is the only reliable method which indicates that a patient may have a pulmonary embolus or does not have a pulmonary embolus. (3) The validity of these conclusions and the ability to apply them widely to ongoing clinical practice is based on the prospective design of the Study which included an appropriate distribution of institutions by type, size, and geographic location. Also, the only judgement samples was that of the referring physician. (ERB)

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.

Diagnostic thyroid procedures and corresponding radiation doses in Manitoba: 1981-1985  

SciTech Connect

Data on nuclear medicine thyroid examinations performed in Manitoba (population 1 million) from 1981-1985 were collected, with more detailed demographic data obtained on 1,100 consecutive patients between June 1987 and January 1988. An average of 2,081 patients were examined per year, 81% female and 19% male, representing 8.4% of all nuclear medicine procedures. Typical administered activity and associated HE per patient were 238.0 MBq and 1.5 mSv for 99mTc, 7.4 MBq and 1.2 mSv for 123I, and 0.33 MBq and 3.9 mSv for 131I. Based on NCRP risk estimates with explicit corrections for age, sex, and radionuclide used, it is estimated that the rate of thyroid cancer induction is unlikely to exceed 0.56 y-1, of which about 10% would be fatal. This estimate is about a factor of 4 less than that generated using more generally applicable radiation protection risk estimates averaged over both sexes and all ages in the general population. The replacement of 131I with the present mix of radiotracers used for thyroid evaluation has resulted in a reduction of the estimated population detriment by a factor of 3.6.

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.

Development of a modified molecular diagnostic procedure for the identification and quantification of naturally occurring strongylid larvae on pastures.  

PubMed

A molecular procedure was developed to detect and quantify larvae of different strongylid parasite species recovered from pasture samples. Two lamb flocks (L and S) grazed separate paddocks with different natural larvae challenges (one low [Paddock L] and one high [Paddock S] challenge) on a commercial farm in Western Australia. Pasture samples were collected and analysed for larvae on 9 separate occasions from each paddock. Pregnant Merino ewes were sampled on 3 separate occasions (2 pre-partum and 1 post-partum). Following lambing, 203 female crossbred lambs were identified, from which faecal samples were collected across five separate samplings. Lamb production and faecal attributes were recorded. Genomic DNA was extracted directly from lamb faeces, in addition to the genomic DNA extracts from strongylid larval species recovered from pastures. Faecal worm egg counts (FWECs) were undertaken. Species-specific qPCRs and conventional PCRs (ITS-2 nuclear ribosomal DNA) were used to screen samples for strongylid species (Teladorsagia circumcincta, Trichostrongylus spp., Haemonchus contortus, Chabertia ovina and Oesophagostomum venulosum). Negative correlations (r(2)>0.91) were found between qPCR C(q) values and log-transformed pasture larval counts for Trichostrongylus spp. and T. circumcincta. Moderate levels of agreement between pasture larval counts and qPCR results were observed (67%). A clear difference in pasture larval challenge levels was observed between the two flocks using both qPCR and conventional pasture larval counts. It is difficult to draw conclusions on the production performances of lambs from the two experimental flocks, as no further replicates were able to be conducted following this experiment. Flock L had higher dressing percentages than Flock S (P=0.038), along with significantly higher faecal consistency and breech fleece faecal soiling scores at successive samplings. The molecular procedures utilised in this study have the potential to be beneficial for livestock grazing management strategies and parasite surveillance, however further investigation is necessary before they can become part of routine diagnostics.

Reliability of stabilised commercial dynamometers for measuring hip abduction strength: a pilot study  

PubMed Central

Background: Reliable quantification of hip abductor strength in a clinical setting is challenging. Objectives: To examine the intrarater and interrater reliability of three commonly used commercial dynamometers in the measurement of hip abduction. Methods: Supine gravity minimised measures of unilateral hip abduction strength were recorded in 10 women (mean (SD) age 23.5 (1.9) years) using three different commercially available dynameters. Measurements were repeated over a three day period with a different device used on each day. Results: Intrarater reliability ranged from 0.880 to 0.958 across the three devices, and measures of interrater reliability ranged from 0.899 to 0.948. Conclusion: Commercially available dynamometers can be used to quantify hip abduction strength with good to excellent reliability. A previously undescribed method of quantifying hip abduction strength in a clinical setting using readily available instrumentation is presented.

Proposal for a trigonometric method to evaluate the abduction angle of the lower limbs in neonates.  

PubMed

It is difficult to precisely measure articular arc movement in newborns using a goniometer. This article proposes an objective method based on trigonometry for the evaluation of lower limb abduction. With the newborn aligned in the dorsal decubitus position, 2 points are marked at the level of the medial malleolus, one on the sagittal line and the other at the end of the abduction. Using the right-sided line between these 2 points and a line from the medial malleolus to the reference point at the anterior superior iliac spine or umbilical scar, an isosceles triangle is drawn, and half of the inferential abduction angle is obtained by calculating the sine. Twenty healthy full-term newborns comprise the study cohort. Intersubject and intrasubject variability among the abduction angle values (mean [SD], 37 degrees [4] degrees) is low. This method is advantageous because the measurement is precise and because the sine can be used without approximation. PMID:19073852

Deficits of reflexive attention induced by abduction of the eye.  

PubMed

Attention mediates access of sensory events to higher cognitive systems and can be driven by either top-down voluntary mechanisms or in a bottom-up, reflexive fashion by the sensory properties of a stimulus. The exact mechanisms underlying these different modes of attention are controversial, but both types of attention appear to be tightly coupled to the systems used for the control of eye-movements. Indeed, recent data indicates that patients with opthalmoplegia (paralysis of the eyes) have difficulty voluntarily attending to locations to which saccades cannot be made (Craighero, Carta, & Fadiga, 2001) and experimentally induced opthalmoplegia disrupts voluntary attention in normal participants. However, the extent to which reflexive attention is mediated by the ability to make eye-movements in normal participants remains unclear. Here, we address this issue by investigating the effect of an experimentally induced opthalmoplegia on voluntary and reflexive attentional orienting during visual search. We observed that abducting the eye into the temporal hemifield elicited deficits of both voluntary and reflexive attention for targets that appeared beyond the oculomotor range. This result confirms the link between oculomotor control and voluntary attention observed in opthalmoplegic patients and demonstrates for the first time that reflexive attention is mediated by the ability to make eye-movements in normal participants.

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

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

PubMed Central

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

Reliability of shoulder abduction strength measure for the Constant-Murley score.  

PubMed

Reports using the Constant-Murley score often lack details regarding how strength measurement was performed, which may have an important impact on the results obtained. A description of the measurement is especially important when patients are unable to adopt the prescribed position of 90 degrees shoulder abduction, leading to invalid or highly discrepant scores. We investigated the influence of shoulder abduction and torso position on strength measurement with special emphasis on intraobserver reliability. Thirty-three healthy volunteers were examined using a handheld dynamometer (Isobex) in 30 degrees , 60 degrees , and 90 degrees abduction with or without stabilization of the torso. A linear correlation between strength measurements in different degrees of abduction was observed, with values at 90 degrees abduction on average 15% lower than at 60 degrees and 45% lower than at 30 degrees . In multivariate analysis, gender and weight had a substantial impact on the strength of individual measurement positions. Intraobserver reliability was related to arm and torso position (intraclass correlation coefficients, 0.71-0.93) and was highest for 90 degrees abduction without torso stabilization. These findings emphasize the importance of standardized torso and arm positions ensuring high reliability when performing the strength measurement of the Constant-Murley score. PMID:19639370

Activation of the gluteus maximus and hamstring muscles during prone hip extension with knee flexion in three hip abduction positions.  

PubMed

The direction of fiber alignment within a muscle is known to influence the effectiveness of muscle contraction. However, most of the commonly used clinical gluteus maximus (GM) exercises do not consider the direction of fiber alignment within the muscle. Therefore, the purpose of this study was to investigate the influence of hip abduction position on the EMG (electromyography) amplitude and onset time of the GM and hamstrings (HAM) during prone hip extension with knee flexion (PHEKF) exercise. Surface EMG signals were recorded from the GM and HAM during PHEKF exercise in three hip abduction positions: 0°, 15°, and 30°. Thirty healthy subjects voluntarily participated in this study. The results show that GM EMG amplitude was greatest in the 30° hip abduction position, followed by 15° and then 0° hip abduction during PHEKF exercise. On the other hand, the HAM EMG amplitude at 0° hip abduction was significantly greater than at 15° and 30° hip abduction. Additionally, GM EMG onset firing was delayed relative to that of the HAM at 0° hip abduction. On the contrary, the GM EMG onset occurred earlier than the HAM in the 15° and 30° hip abduction positions. These findings indicate that performing PHEKF exercise in the 30° hip abduction position may be recommended as an effective way to facilitate the GM muscle activity and advance the firing time of the GM muscle in asymptomatic individuals. This finding provides preliminary evidence that GM EMG amplitude and onset time can be modified by the degree of hip abduction. PMID:23312068

Methylation-sensitive high-resolution melting in the context of legislative requirements for validation of analytical procedures for diagnostic applications.  

PubMed

Temperature gradient was first used to identify the methylation status of the DNA sequence over 10 years ago; however, the initially published protocol was shown to have poor analytical sensitivity. Recent developments in the field of DNA melting technologies, combined with the identification of procedures to overcome the sensitivity issues in the PCR-based methylation detection applications, led to the development of the methylation-sensitive high-resolution melting (MS-HRM) protocol. This protocol allows for highly sensitive detection of methylation levels in a labor- and cost-efficient fashion. Moreover, it enables investigation of methylation status of imprinted loci as well as identification of heterogeneous methylation. The MS-HRM technology is being increasingly applied in research laboratories and has a potential for future application in diagnostic settings. The focus of this article is to describe the development of the HRM technology for methylation analyses and evaluate the diagnostic applicability of the MS-HRM technology. PMID:22133118

The diagnosis of spinal neuro-musculoskeletal dysfunction is a pre-requisite for application of spinal manual therapy. Different disciplines rely on palpatory procedures to establish this diagnosis and design treatment plans. Over the past 30 years, the osteopathic, chiropractic, physical therapy and allopathic professions have investigated the validity and reliability of spinal palpatory procedures. We explored the literature from all four disciplines looking for scientific papers studying the content validity and reliability of spinal palpatory procedures. Thirteen databases were searched for relevant papers between January 1966 and October 2001. An annotated bibliography of these articles is presented and organized by the type of test used.

Cumulative Exposure to Ionizing Radiation from Diagnostic and Therapeutic Cardiac Imaging Procedures: A Population-Based Analysis  

PubMed Central

Objectives To describe radiation exposure from cardiac imaging procedures over time in a general population. Background Cardiac imaging procedures frequently expose patients to ionizing radiation, but their contribution to effective doses of radiation in the general population is unknown. Methods We used administrative claims to identify cardiac imaging procedures performed from 2005-2007 in 952,420 non-elderly insured adults in 5 U.S. healthcare markets. We estimated 3-year cumulative effective doses of radiation in millisieverts (mSv) from these procedures We then calculated population-based annual rates of radiation exposure to effective doses ?3 mSv/year (background level of radiation from natural sources), >3-20 mSv/year, or >20 mSv/year (upper annual limit for occupational exposure averaged over 5 years). Results 90,121 (9.5%) individuals underwent at least one cardiac imaging procedure using radiation. Among patients who underwent ?1 cardiac imaging procedure, the mean cumulative effective dose over 3 years was 16.4 mSv (range 1.5-189.5 mSv). Myocardial perfusion imaging accounted for 74% of the cumulative effective dose. Overall, 47.8% of cardiac imaging procedures were performed in physician offices; this proportion was higher for myocardial perfusion imaging (74.8%) and cardiac CT studies (76.5%). The annual population-based rate of receiving an effective dose of >3-20 mSv/year was 89.0 per 1000; and 3.3 per 1000 for cumulative doses >20 mSv/year. Annual effective doses increased with age and were generally higher among men. Conclusions Cardiac imaging procedures lead to substantial radiation exposure and effective doses for many patients in the United States.

A community outbreak of Legionnaires' disease from an industrial cooling tower: assessment of clinical features and diagnostic procedures.  

PubMed

An outbreak of Legionnaires' disease (LD) occurred in Lidköping, Sweden, in August 2004. A cooling tower was identified as the probable source of infection. During the outbreak period an unexpected 3-6-fold increase in pneumonia patients was noted at the local hospital. During 7 weeks LD was diagnosed in 15 patients by urinary antigen and/or sputum culture. Additionally, 15 LD patients were diagnosed later by serology. Patients with LD were generally younger, more healthy, and more often smokers compared to other pneumonia patients. On admittance they had more severe symptoms with high fever and raised CRP levels, and more often hyponatraemia, gastrointestinal and CNS symptoms. A causative agent besides Legionella was found in 2 patients only. A significant titre rise for Mycoplasma and/or Chlamydophila pneumoniae was found in 13 of 29 tested patients with confirmed LD. We conclude that the clinical diagnosis of LD is difficult and that available diagnostic methods detect only a minority of patients in the acute phase. Therefore in severe pneumonia, empirically targeted therapy should be instituted on clinical grounds irrespective of the results of diagnostic tests. The observation of increased antibody levels for M. and C. pneumoniae suggests an unspecific immune reaction and merits further study. PMID:17366051

[SICI-GISE position paper on the requirements for diagnostic and interventional procedures in patients with peripheral arterial disease].  

PubMed

Interventional procedures on peripheral vessels are the field of a novel specialty dedicated to the diagnosis and minimally invasive endovascular treatment of diseases involving the cerebral, thoracic and abdominal arteries (including renal and visceral arteries), as well as the peripheral arteries (femoro-popliteal arteries and the arteries below the knee). At present, physicians with three different types of medical training, each involving particular strengths and characteristics, specialize in endovascular treatment of patients with peripheral arterial disease: vascular surgeons, interventional radiologists and interventional cardiologists. Treatment of high-risk patients in terms of anatomical and clinical (serious comorbidities) complexity raised the need for the interventional cardiologist to face issues related to technical aspects of the procedure, multilevel pathology management and adequate indication. To achieve this goal, interventional cardiologists require particular facilities and clinical skills. The objectives of this position paper from the Italian Society of Interventional Cardiology (SICI-GISE) are (i) to define the theoretical background and practical training required to ensure that interventional cardiologists maintain high-quality standards also in the field of treatment of peripheral arterial disease, by establishing shared rules and drafting papers; (ii) to standardize the procedures of interventional cardiology operational units that treat patients with peripheral arterial disease in Italy on the basis of scientific evidence, and (iii) to establish common requirements in terms of facilities and regulations.

Abduction pillow immobilization following hip surgery: a welcome alternative for selected patients  

PubMed Central

Background Studies have shown that when using a spica cast following hip surgery in children , there are associated complications such as soiling, pressure sores, and osteopenic fractures. Methods Charts were retrospectively reviewed for all patients who had undergone hip surgeries by one surgeon at one institution between 1999 and 2005. The method of post-operative immobilization (spica cast or abduction pillow) and complications were recorded for each patient. Results There was a total of 32 patients. Of these, 11—all of whom had a diagnosis of developmental dysplasia of the hip—were treated using a spica cast. In the 21 patients treated in an abduction pillow, 4 (19%) were switched to a spica cast for the following reasons: (1) distal femoral fracture as a result of vigorous resuscitation during a choking episode, (2) parental preference, (3) for added immobilization over concern of implant loss of fixation, and (4) concern of migration of the hip, which again migrated after being changed to a spica cast and eventually required a pelvic osteotomy. Conclusion It is our opinion that only one of these complications in the children treated with an abduction pillow (the case of possible implant migration) may have been avoided if the child had originally been placed in a spica cast. The child who was successfully resuscitated after a choking incident weeks after the surgery may have had a worse outcome if it had been in a spica cast. This incident occurred at home and the abduction pillow was easily and quickly removed to allow resuscitation. An abduction pillow is a welcome alternative to a spica cast following hip surgery for many patients with neuromuscular and syndromic conditions. However, in children with osteopenic bone at risk for implant failure and in children with unstable hip reductions, a spica cast may be preferable.

Inferences of clinical diagnostic reasoning and diagnostic error.

This paper discusses clinical diagnostic reasoning in terms of a pattern of If/then/Therefore reasoning driven by data gathering and the inference of abduction, as defined in the present paper, and the inferences of retroduction, deduction, and induction as defined by philosopher Charles Sanders Peirce. The complex inferential reasoning driving clinical diagnosis often takes place subconsciously and so rapidly that its nature remains largely hidden from the diagnostician. Nevertheless, we propose that raising such reasoning to the conscious level reveals not its basic pattern and basic inferences, it also reveals where errors can and do occur and how such errors might be reduced or even eliminated.

Fetal infection from rubeovirus or cytomegalovirus: correlation among maternal serological profiles, invasive diagnostic procedures, and long-term follow-up.  

PubMed

Different variables influence the possibility that maternal viral infection may be transmitted to the fetus, although not all fetal infections result in fetal "illness" with consequent fetopathy. As concerns the fetus, prenatal diagnosis includes invasive techniques necessary for fetal tissue sampling. These techniques carry some risks. The fetal infectious risk, as determined by maternal clinico-serological profile and according to sonographic investigation, always should be weighed against the risks and benefits of invasive diagnostic procedures. The present study re-elaborates the criteria necessary for defining fetal risk as related to the maternal serological profile. In the 26 mothers with rubeola infection, the incidence of fetal mortality was 7.7%. Fetal prognosis worsens with the precocity of eruption. In these cases the esantema is the most reliable prognostic element as an indication to perform the invasive procedure. In the 15 patients with cytomegalovirus infection, no fetal or postnatal losses occurred. Morbidity occurred in 13.3% of cases, and the two ill fetuses were classified in the same risk group. In this group of patients, the maternal serological profile is a significant predictor of fetal morbidity. PMID:9502669

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

Recurrent neural networks with backtrack-points and negative reinforcement applied to cost-based abduction.  

PubMed

Abduction is the process of proceeding from data describing a set of observations or events, to a set of hypotheses which best explains or accounts for the data. Cost-based abduction (CBA) is an AI formalism in which evidence to be explained is treated as a goal to be proven, proofs have costs based on how much needs to be assumed to complete the proof, and the set of assumptions needed to complete the least-cost proof are taken as the best explanation for the given evidence. In this paper, we present two techniques for improving the performance of high order recurrent networks (HORN) applied to cost-based abduction. In the backtrack-points technique, we use heuristics to recognize early that the network trajectory is moving in the wrong direction; we then restore the network state to a previously stored point, and apply heuristic perturbations to nudge the network trajectory in a different direction. In the negative reinforcement technique, we add hyperedges to the network to reduce the attractiveness of local minima. We apply these techniques to a suite of six large CBA instances, systematically generated to be difficult. PMID:16112843

Measurement of active abduction of metacarpophalangeal joints via electronic digital incinometric technique.  

PubMed

To define the usefulness of electronic digital inclinometric (EDI) method to measure active abduction of metacarpophalangeal joints and to determine the mean scores. A modified electronic digital inclinometric method which was specifically designed to measure range of joint movements was administered to metacarpophalangeal joints of 20 male and 21 female university students. Active abduction of each metacarpophalangeal joint of both dominant and non-dominant hands were measured and recorded separately. Results were presented as mean +/- standart deviation and statistical analysis of data was performed. First data obtained for Turkish people were as follows: 4.12 degrees for thumb, 41.9 degrees for index finger, 80.98 degrees for median finger (approximately twice of others as it was the sum of radial and ulnar abductions), 41.57 degrees for ring finger and 48.53 degrees for little finger. Electronic digital inclinometer was found to be safe, practical and useful in the measurement of active movement ranges of metacarpophalangeal joints. PMID:16736713

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

Optimization of diagnostic RT-PCR protocols and sampling procedures for the reliable and cost-effective detection of Cassava brown streak virus.  

PubMed

Sampling procedures and diagnostic protocols were optimized for accurate diagnosis of Cassava brown streak virus (CBSV) (genus Ipomovirus, family Potyviridae). A cetyl trimethyl ammonium bromide (CTAB) method was optimized for sample preparation from infected cassava plants and compared with the RNeasy plant mini kit (Qiagen) for sensitivity, reproducibility and costs. CBSV was detectable readily in total RNAs extracted using either method. The major difference between the two methods was in the cost of consumables, with the CTAB 10x cheaper (0.53 pounds sterling=US$0.80 per sample) than the RNeasy method (5.91 pounds sterling=US$8.86 per sample). A two-step RT-PCR (1.34 pounds sterling=US$2.01 per sample), although less sensitive, was at least 3-times cheaper than a one-step RT-PCR (4.48 pounds sterling=US$6.72). The two RT-PCR tests revealed consistently the presence of CBSV both in symptomatic and asymptomatic leaves and indicated that asymptomatic leaves can be used reliably for virus diagnosis. Depending on the accuracy required, sampling 100-400 plants per field is an appropriate recommendation for CBSD diagnosis, giving a 99.9% probability of detecting a disease incidence of 6.7-1.7%, respectively. CBSV was detected at 10(-4)-fold dilutions in composite sampling, indicating that the most efficient way to index many samples for CBSV will be to screen pooled samples. The diagnostic protocols described below are reliable and the most cost-effective methods available currently for detecting CBSV. PMID:19879299

Child abduction: aged-based analyses of offender, victim, and offense characteristics in 550 cases of alleged child disappearance.  

PubMed

Crimes against children, particularly cases involving abduction and/or homicide, continue to be problematic as both a social phenomenon and judicial responsibility. Such cases routinely receive immense community and media attention and rapidly overwhelm investigative resources. Research in the area of childhood victimization, however, has only recently gained national prominence. While numerous studies on child abuse and neglect have been conducted, research on child abduction and homicide remains scant. Previous studies examining child abduction suffer from limited geographical scope or fail to base predictive analyses on victim characteristics. The current study reports the results of a nationally representative sample (47 states, the District of Columbia, and Puerto Rico) of 550 cases of alleged child abduction obtained from Federal Bureau of Investigation files for the period 1985 through 1995. Study results demonstrate that both offender and offense characteristics vary significantly according to victim age, gender, and race. Such differences appear critical to crime reconstruction, criminal profiling, and investigative resolution. Additionally, these data suggest that current child abduction prevention programs may emphasize inaccurate offender traits. PMID:10408108

Successful Outcome of Modified Quad Surgical Procedure in Preteen and Teen Patients with Brachial Plexus Birth Palsy  

PubMed Central

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

The urgent need for universally applicable simple screening procedures and diagnostic criteria for gestational diabetes mellitus - lessons from projects funded by the World Diabetes Foundation  

PubMed Central

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

Comparative reliability of the make and break tests for hip abduction assessment.  

PubMed

Objective: To investigate the reliability of "make test" (MT) and "break test" (BT) of hip abduction using hand-held dynamometry. Design: A repeated measures reliability assessment design for the estimation of inter-rater reliability, in which pairs of testers rated each subject in a 2/3 fractional factorial was used. Both tests ("BT" and "MT") were performed on both legs twice by 2 testers, for a total of 16 ratings for each participant. Participants: 39 healthy subjects between the ages of 21 and 70 years old volunteered. Main outcome measure: Variance components were computed from the repeated measures to assess inter-rater reliability of measurement. Reliability was estimated as a ratio of variance components. Results: Both tests proved to be highly reliable in nature with values above 0.87 overall. Further examination revealed that gender had a small effect on reliability, yet differences in results were noted between raters on the BT more than the MT. Conclusions: Hip abduction strength can be measured and reproduced between testers reliably using both a "MT" and "BT" and a long lever arm with pelvic stabilization. Statistically, the "MT" appears to be slightly more reliable than the "BT", but clinically, the "BT" is more practical and convenient. PMID:23706084

Unilateral foot abduction orthosis: is it a substitute for Denis Browne boots following Ponseti technique?  

PubMed

The use of foot abduction orthosis [Denis Browne boot (DBB)] is vital for maintaining correction after the Ponseti technique for treating idiopathic clubfoot. Lack of adherence to DBB regimen is reported to be a potent cause for recurrence. Adherence to the boots and bars programme is difficult and patients sometimes resist their use. The evaluation of alternatives that may facilitate adherence is therefore necessary and reasonable. There are less data published regarding the outcome after the use of alternative splints. In patients who showed poor adherence to DBB, we introduced a novel unilateral foot abduction orthosis (UFAO) as an alternative. The aim of this study was to determine whether the recurrence rates were increased by exchanging DBB with UFAO in nonadherent patients and to find out whether UFAO was more acceptable to families who had refused to use DBB. We reviewed 27 children with 35 idiopathic clubfeet. Twenty-three patients used the boots and bars programme for the first 3 months after completion of serial casting, before UFAO was introduced into the treatment plan for resistance to DBB usage. In four cases, UFAO was commenced immediately after the serial casting. The mean follow-up was 25 months (16-36 months). Most families reported that UFAO was easier for their child to use and facilitated adherence was observed. Recurrence (the need for further casting or operation) was observed in 11 feet. Six of these 11 recurrences responded favourably to a further period of serial casting with or without repeated tendoachilles tenotomy. Three of these 11 patients responded favourably to tibialis anterior transfer and two required a traditional posteromedial release. The recurrence rates in patients using UFAO were higher compared with those reported by others using DBB after Ponseti serial casting. Our results indicated that although a unilateral orthosis is preferred and accepted by families who do not adhere to a DBB regimen, recurrence with UFAO use is higher. This study therefore questions the effectiveness of UFAO as an alternative to DBB. The importance of following the original method described by Ponseti should be stressed. PMID:21030881

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.

Arm adductor with arm abduction in rotator cuff tear patients vs. healthy--design of a new measuring instrument.  

PubMed

The incidence of (a)symptomatic rotator cuff tears is high, but etiologic mechanisms are unclear and treatment outcomes vary. A practical tool providing objective outcome measures and insight into etiology and potential patient subgroups is desirable. Symptomatic cuff tears coincide with humerus cranialization. Adductor co-activation during active arm abduction has been reported to reduce subacromial narrowing and pain in cuff patients. We present an easy-to-use method to evaluate adductor co-activation. Twenty healthy controls and twenty full-thickness cuff tear patients exerted EMG-recorded isometric arm abduction and adduction tasks. Ab- and adductor EMG's were expressed using the "Activation Ratio (AR)" (-1 ? AR ? 1), where lower values express more co-activation. Mean control AR's ranged from .7 to .9 with moderate to good test-retest reliability (ICC: .60-.74). Patients showed significantly more adductor co-activation during abduction, with adductor AR's ranging between .3 (teres major) and .5 (latissimus dorsi). In conclusion, the introduced method discriminates symptomatic cuff tear patients from healthy controls, quantifies adductor co-activation in an interpretable measure, and provides the opportunity to study correlations between muscle activation and humerus cranialization in a straightforward manner. It has potential as an objective outcome measure, for distinguishing symptomatic from asymptomatic cuff tears and as a tool for surgical or therapeutic decision-making. PMID:22341875

Results of operative treatment of displaced external rotation-abduction fractures of the ankle.  

PubMed

One hundred and fifty patients with a displaced fracture of the ankle caused by external rotation-abduction forces were treated by open reduction and rigid internal fixation. After an average follow-up of three and one-half years, the results were satisfactory in 90 per cent. Less satisfactory results were noted in the more severely injured ankles. We found that the ruptured deltoid ligament did not need to be repaired if the lateral side was anatomically and rigidly fixed; in the Maisonneuve fracture, restoration of the fibular length was as important as stabilization of the fracture; with the use of the suprasyndesmotic screw, walking was permissible with the screw in situ; conforming the plate to the bend of the lateral malleolus was essential; and as much as two millimeters of lateral residual displacement of the lateral and medial malleoli was compatible with a satisfactory result, as was a similar displacement of the talus provided there was anatomical restoration of the lateral side.

Comparison of two methods for computing abduction moment arms of the rotator cuff.  

PubMed

Biomechanical models of the shoulder mechanism require estimates of muscle moment arm magnitude. Some shoulder models have estimated muscle moment arms by assuming an idealized minimum distance path from the origin to insertion that passes around the bony geometry. Alternatively, the principle of virtual work can be used to estimate moment arms from tendon excursion and joint-angle data. The purpose of this study was to determine if these two methods give different estimates of abduction moment arms for the supraspinatus, infraspinatus, and subscapularis muscles. Muscle moment arms were estimated for these muscles on ten fresh frozen cadaver specimens. The results showed a significant difference between the two estimation methods. Average differences were 3.1 mm (10.6%), 3.9 mm (43.9%), and 7.2 mm (70.3%) for the supraspinatus, subscapularis, and infraspinatus muscles, respectively. These results suggest that shoulder models based on the origin-insertion method may give higher rotator cuff muscle force estimates than methods using the slope of the tendon excursion vs joint angle relationship.

Comparison of HIV-related vulnerabilities between former child soldiers and children never abducted by the LRA in northern Uganda  

PubMed Central

Background Thousands of former child soldiers who were abducted during the prolonged conflict in northern Uganda have returned to their home communities. Programmes that facilitate their successful reintegration continue to face a number of challenges. Although there is increasing knowledge of the dynamics of HIV infection during conflict, far less is known about its prevalence and implications for population health in the post-conflict period. This study investigated the effects of abduction on the prevalence of HIV and HIV-risk behaviours among young people in Gulu District, northern Uganda. An understanding of abduction experiences and HIV-risk behaviours is vital to both the development of effective reintegration programming for former child soldiers and the design of appropriate HIV prevention interventions for all young people. Methods In 2010, we conducted a cross-sectional study of 2 sub-counties in Gulu District. A demographic and behavioural survey was interview-administered to a purposively selected sample of 384 transit camp residents aged 15–29. Biological specimens were collected for HIV rapid testing in the field and confirmatory laboratory testing. Descriptive statistics were used to describe characteristics of abduction. Additionally, a gender-stratified bivariate analysis compared abductees’ and non-abductees’ HIV risk profiles. Results Of the 384 participants, 107 (28%) were former child soldiers (61% were young men and 39% were young women). The median age of participants was 20 and median age at abduction was 13. HIV prevalence was similar among former abductees and non-abductees (12% vs. 13%; p?=?0.824), with no differences observed by gender. With respect to differences in HIV vulnerability, our bivariate analysis identified greater risky sexual behaviours in the past year for former abductees than non-abductees, but there were no differences between the two groups’ survival/livelihood activities and food insufficiency experiences, both overall and by gender. The analysis further revealed that young northern Ugandans in general are in desperate need of education, skills development, and support for victims of sexual violence. Conclusions This study persuasively demonstrates that all young people in northern Ugandan have been similarly affected by HIV infection during war and displacement. Post-conflict programme planners must therefore abandon rudimentary targeting practices based on abductees as a high-profile category. Instead, they must develop evidence-based HIV interventions that are commensurate with young people’s specific needs. As such programmes will be less stigmatizing, more oriented to self-selection, and more inclusive, they will effectively reach the most vulnerable young people in northern Uganda.

[Hemorrhages from the gastrointestinal tract in middle-aged and elderly patients--the diagnostic-treatment procedures and mortality dynamics].  

PubMed

Hemorrhages from the upper part of the gastrointestinal tract pose serious surgical problems because of their rather elevated incidence, diverse etiopathogenesis, difficulties in diagnostic and therapeutic approach, and last but not least, owing to the high mortality rate. The incidence of patients with ulcers amount to 420 per 100,000 population, with those in advanced and old-age accounting for 15-40 per cent of the total number of affections. In this contingent ulcers run a course associated with a number of peculiarities conditioned by severe lesions, caused by an acute and prolonged blood loss, not infrequently associated with a serious co-morbidity typical of this age. For this reason periodic analysis of lethality due to hemorrhages in the upper segments of the gastrointestinal tract contribute greatly: to evaluate the factors affecting thanatogenesis of this particular disease. establish the dynamic pattern of mortality, and specify the therapeutic tactics influencing such dynamics.

Anatomical dissections in seven horses revealed two possible donor nerve-pedicle grafts: the omohyoid and the sternothyrohyoid, both innervated by a branch of the first and second cervical nerves. Histochemical evaluations in two ponies of the dorsal cricoarytenoid, omohyoid and sternothyrohyoid muscles revealed similar proportions of fiber types 1 and 2 in all three muscles. Electromyographic studies in these two ponies revealed that the omohyoid and sternothyrohyoid muscles contract synchronously with respirations during forced inspiration under general anesthesia. Based on surgical ease of access, a 1 cm2 portion of the omohyoid muscle at the point of penetration of the second cervical nerve was used as a nerve-muscle pedicle graft in an attempt to reinnervate the left dorsal cricoarytenoid muscle in four ponies. These four ponies (as well as three others which served as controls) had previously undergone left recurrent laryngeal nerve transection. All seven ponies endoscopically showed signs of complete left laryngeal hemiplegia immediately postoperatively. Animals were monitored endoscopically for 30 weeks after surgery. The three control ponies showed no abduction of the arytenoid cartilage. In addition, in these three ponies, histological and histochemical expected changes of muscle fiber atrophy and fibrosis were present in the dorsal cricoarytenoid muscle.(ABSTRACT TRUNCATED AT 250 WORDS) Images Fig. 1.

Abductive Equivalential Translation and its application to Natural Language Database Interfacing  

NASA Astrophysics Data System (ADS)

The thesis describes a logical formalization of natural-language database interfacing. We assume the existence of a ``natural language engine'' capable of mediating between surface linguistic string and their representations as ``literal'' logical forms: the focus of interest will be the question of relating ``literal'' logical forms to representations in terms of primitives meaningful to the underlying database engine. We begin by describing the nature of the problem, and show how a variety of interface functionalities can be considered as instances of a type of formal inference task which we call ``Abductive Equivalential Translation'' (AET); functionalities which can be reduced to this form include answering questions, responding to commands, reasoning about the completeness of answers, answering meta-questions of type ``Do you know...'', and generating assertions and questions. In each case, a ``linguistic domain theory'' (LDT) ? and an input formula F are given, and the goal is to construct a formula with certain properties which is equivalent to F, given ? and a set of permitted assumptions. If the LDT is of a certain specified type, whose formulas are either conditional equivalences or Horn-clauses, we show that the AET problem can be reduced to a goal-directed inference method. We present an abstract description of this method, and sketch its realization in Prolog. The relationship between AET and several problems previously discussed in the literature is discussed. In particular, we show how AET can provide a simple and elegant solution to the so-called ``Doctor on Board'' problem, and in effect allows a ``relativization'' of the Closed World Assumption. The ideas in the thesis have all been implemented concretely within the SRI CLARE project, using a real projects and payments database. The LDT for the example database is described in detail, and examples of the types of functionality that can be achieved within the example domain are presented.

Systematic Study of Structured Diagnostic Procedures in Outpatient Psychiatric Rehabilitation: A Three-year, Three-cohort Study of the Stability of Psychiatric Diagnoses  

PubMed Central

Background. Psychiatric diagnoses are important for treatment planning. There are a number of current challenges in the area of psychiatric diagnosis with important treatment implications. In this study, we examined the differential usefulness of two semi-structured interviews of differing length compared to clinical diagnoses for generation of diagnoses that did not require modification over the course of treatment. Methods. We performed a three-year, three-cohort study at an outpatient psychiatric rehabilitation facility, comparing the stability of admission diagnoses when generated by unstructured procedures relying on referring clinician diagnosis, the SCID, and the MINI. We examined changes in diagnoses from admission to discharge (averaging 13 weeks) and, during the second two years, convergence between referring clinician diagnoses and those generated by structured interviews. The same three interviewers examined all patients in all three phases of the study. Results. Admission and discharge diagnoses were available for 313 cases. Diagnoses generated with the unstructured procedure were changed by discharge 74 percent of the time, compared to four percent for SCID diagnoses and 11 percent for MINI diagnoses. Referring clinician diagnoses were disconfirmed in Years 2 and 3 in 56 percent of SCID cases and 44 percent of MINI cases. The distinctions between unipolar and bipolar disorders were particular points of disagreement, with similar rates of under and over-diagnosis of bipolar disorder. The rate of confirmation of referring clinician diagnoses of schizoaffective disorder was 10 percent with the SCID and 11 percent with the MINI. Discussion. In this setting, there appears to be a reasonable trade-off between brevity and accuracy through the use of the MINI compared to the SCID, with substantial improvements in stability of diagnoses compared to clinician diagnoses. Clinical diagnoses were minimally overlapping with the results of structured diagnoses, suggesting that structured assessment, particularly early in the illness or in short term treatment settings, may improve treatment planning.

Successful outcome of modified quad surgical procedure in preteen and teen patients with brachial plexus birth palsy.  

PubMed

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

An evaluation of the dot-ELISA procedure as a diagnostic test in an area with a high prevalence of human Toxocara canis infection.  

PubMed

The aim of this work was to evaluate a dot-enzyme-linked immunosorbent assay (dot-ELISA) using excretory-secretory antigens from the larval stages of Toxocara canis for the diagnosis of toxocariasis. A secondary aim was to establish the optimal conditions for its use in an area with a high prevalence of human T. canis infection. The dot-ELISA test was standardised using different concentrations of the antigen fixed on nitrocellulose paper strips and increasing dilutions of the serum and conjugate. Both the dot-ELISA and standard ELISA methods were tested in parallel with the same batch of sera from controls and from individuals living in the problem area. The best results were obtained with 1.33 µg/mL of antigen, dilutions of 1/80 for the samples and controls and a dilution of 1/5,000 for the anti-human IgG-peroxidase conjugate. All steps of the procedure were performed at room temperature. The coincidence between ELISA and dot-ELISA was 85% and the kappa index was 0.72. The dot-ELISA test described here is rapid, easy to perform and does not require expensive equipment. Thus, this test is suitable for the serological diagnosis of human T. canis infection in field surveys and in the primary health care centres of endemic regions. PMID:22415257

A comparison of ankle foot orthoses with foot abduction orthoses to prevent recurrence following correction of idiopathic clubfoot by the Ponseti method.  

PubMed

The Ponseti method of clubfoot management requires a period of bracing in order to maintain correction. This study compared the effectiveness of ankle foot orthoses and Denis Browne boots and bar in the prevention of recurrence following successful initial management. Between 2001 and 2003, 45 children (69 feet) with idiopathic clubfeet achieved full correction following Ponseti casting with or without a tenotomy, of whom 17 (30 clubfeet) were braced with an ankle foot orthosis while 28 (39 clubfeet) were prescribed with Denis Browne boots and bar. The groups were similar in age, gender, number of casts and tenotomy rates. The mean follow-up was 60 months (50 to 72) in the ankle foot orthosis group and 47 months (36 to 60) in the group with boots and bars. Recurrence requiring additional treatment occurred in 25 of 30 (83%) of the ankle foot orthosis group and 12 of 39 (31%) of the group with boots and bars (p < 0.001). Additional procedures included repeat tenotomy (four in the ankle foot orthosis group and five in the group treated with boot and bars), limited posterior release with or without tendon transfers (seven in the ankle foot orthosis group and two in the group treated with boots and bars), posteromedial releases (nine in the orthosis group) and midfoot osteotomies (five in the orthosis group, p < 0.001). Following initial correction by the Ponseti method, children managed with boots and bars had far fewer recurrences than those managed with ankle foot orthoses. Foot abduction appears to be important to maintain correction of clubfeet treated by the Ponseti method, and this cannot be achieved with an ankle foot orthosis. PMID:21511939

Symptomatic cardiac metastases of breast cancer 27 years after mastectomy: a case report with literature review - pathophysiology of molecular mechanisms and metastatic pathways, clinical aspects, diagnostic procedures and treatment modalities  

PubMed Central

Metastases to the heart and pericardium are rare but more common than primary cardiac tumours and are generally associated with a rather poor prognosis. Most cases are clinically silent and are undiagnosed in vivo until the autopsy. We present a female patient with a 27-year-old history of an operated primary breast cancer who was presented with dyspnoea, paroxysmal nocturnal dyspnoea and orthopnoea. The clinical signs and symptoms aroused suspicion of congestive heart failure. However, the cardiac metastases were detected during a routine cardiologic evaluation and confirmed with computed tomography imaging. Additionally, this paper outlines the pathophysiology of molecular and clinical mechanisms involved in the metastatic spreading, clinical presentation, diagnostic procedures and treatment of heart metastases. The present case demonstrates that a complete surgical resection and systemic chemotherapy may result in a favourable outcome for many years. However, a lifelong medical follow-up, with the purpose of a detection of metastases, is highly recommended. We strongly call the attention of clinicians to the fact that during the follow-up of all cancer patients, such heart failure may be a harbinger of the secondary heart involvement.

A parental report on the long-term consequences for children of abduction by the other parent.  

PubMed

Little is known about the long-term impact on the child of abduction by a parent. Children who had been kidnapped by one of their parents and hidden for an average of 2.7 years have been followed for a decade through contact with the parent who recovered them. This study reports on the most recent series of interviews. It was hypothesized that children who were now late teens and young adults would, on the whole, be progressing satisfactorily into young adulthood and that relationships with their parents would be non-problematic. According to 32 parental reports gleaned both from a telephone interview with open-ended and closed-ended questions and from a brief mailed questionnaire with closed-ended questions, a significant minority of the children continue to suffer emotionally and may be having more physical ailments than their peers. Relations with recovering parents were non-problematic. PMID:11033929

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.

Hip abduction weakness in elite junior footballers is common but easy to correct quickly: a prospective sports team cohort based study  

PubMed Central

Background Hip abduction weakness has never been documented on a population basis as a common finding in a healthy group of athletes and would not normally be found in an elite adolescent athlete. This study aimed to show that hip abduction weakness not only occurs in this group but also is common and easy to correct with an unsupervised home based program. Methods A prospective sports team cohort based study was performed with thirty elite adolescent under-17 Australian Rules Footballers in the Australian Institute of Sport/Australian Football League Under-17 training academy. The players had their hip abduction performance assessed and were then instructed in a hip abduction muscle training exercise. This was performed on a daily basis for two months and then they were reassessed. Results The results showed 14 of 28 athletes who completed the protocol had marked weakness or a side-to-side difference of more than 25% at baseline. Two months later ten players recorded an improvement of ? 80% in their recorded scores. The mean muscle performance on the right side improved from 151 Newton (N) to 202 N (p<0.001) while on the left, the recorded results improved from 158 N to 223 N (p<0.001). Conclusions The baseline values show widespread profound deficiencies in hip abduction performance not previously reported. Very large performance increases can be achieved, unsupervised, in a short period of time to potentially allow large clinically significant gains. This assessment should be an integral part of preparticipation screening and assessed in those with lower limb injuries. This particular exercise should be used clinically and more research is needed to determine its injury prevention and performance enhancement implications.

The wrist hyperflexion and abduction of the thumb (WHAT) test: a more specific and sensitive test to diagnose de Quervain tenosynovitis than the Eichhoff's Test.  

PubMed

De Quervain's disease has different clinical features. Different tests have been described in the past, the most popular test being the Eichhoff's test, often wrongly named as the Finkelstein's test. Over the years, a misinterpretation has occurred between these two tests, the latter being confused with the first. To compare the Eichhoff's test with a new test, the wrist hyperflexion and abduction of the thumb test, we set up a prospective study over a period of three years for a cohort of 100 patients (88 women, 12 men) presenting spontaneous pain over the radial side of the styloid of the radius (de Quervain tendinopathy). The purpose of the study was to compare the accuracy of the Eichhoff's test and wrist hyperflexion and abduction of the thumb test to diagnose correctly de Quervain's disease by comparing clinical findings using those tests with the results on ultrasound. The wrist hyperflexion and abduction of the thumb test revealed greater sensitivity (0.99) and an improved specificity (0.29) together with a slightly better positive predictive value (0.95) and an improved negative predictive value (0.67). Moreover, the study showed us that the wrist hyperflexion and abduction of the thumb test is very valuable in diagnosing dynamic instability after successful decompression of the first extensor compartment. Our results support that the wrist hyperflexion and abduction of the thumb test is a more precise tool for the diagnosis of de Quervain's disease than the Eichhoff's test and thus could be adopted to guide clinical diagnosis in the early stages of de Quervain's tendinopathy.

A novel, non-invasive diagnostic clinical procedure for the determination of an oxygenation status of chronic lower leg ulcers using peri-ulceral transcutaneous oxygen partial pressure measurements: results of its application in chronic venous insufficiency (CVI).  

PubMed

The basis for the new procedure is the simultaneous transcutaneous measurement of the peri-ulceral oxygen partial pressure (tcPO(2)), using a minimum of 4 electrodes which are placed as close to the wound margin as possible, additionally, as a challenge the patient inhales pure oxygen for approximately 15 minutes. In order to evaluate the measurement data and to characterise the wounds, two new oxygen parameters were defined: (1) the oxygen characteristic (K-PO(2)), and (2) the oxygen inhomogeneity (I-PO(2)) of a chronic wound. The first of these is the arithmetic mean of the two lowest tcPO(2) measurement values, and the second is the variation coefficient of the four measurement values. Using the K-PO(2) parameter, a grading of wound hypoxia can be obtained. To begin with, the physiologically regulated (and still compensated) hypoxia with K-PO(2) values of between 35 and 40 mmHg is distinguished from the pathological decompensated hypoxia with K-PO(2) values of between 0 and 35 mmHg; the first of these still stimulates self-healing (within the limits of the oxygen balance). The decompensated hypoxia can be (arbitrarily) divided into "simple" hypoxia (Grade I), intense hypoxia (Grade II) and extreme hypoxia (Grade III), with the possibility of intermediate grades (I/II and II/III).Measurements were carried out using the new procedure on the skin of the right inner ankle of 21 healthy volunteers of various ages, and in 17 CVI (chronic venous insufficiency) wounds. Sixteen of the 17 CVI wounds (i.e., 94%) were found to be pathologically hypoxic, a state which was not found in any of the healthy volunteers. The oxygen inhomogeneity (I-PO(2)) of the individual chronic wounds increased exponentially as a function of the hypoxia grading (K-PO(2)), with a 10-fold increase with extreme hypoxia in contrast to a constant value of approximately 14% in the healthy volunteers. This pronounced oxygen inhomogeneity explains inhomogeneous wound healing, resulting in the so-called mosaic wounds. The hypoxia grades found in all of the chronic wounds was seen to be evenly distributed with values ranging from 0 to 40 mmHg, and therefore extremely inhomogeneous. In terms of oxygenation, chronic wounds are therefore inhomogeneous in two respects: (1) within the wound itself (intra-individual wound inhomogeneity) and (2) between different wounds (inter-individual wound inhomogeneity). Due to the extreme oxygen inhomogeneity, single measurements are not diagnostically useful. In healthy individuals the oxygen inhalation challenge (see above) results in synchronised tcPO(2) oscillations occurring at minute rhythms, which are not seen in CVI wounds. These oscillations can be interpreted as a sign of a functioning arterial vasomotor system.The new procedure is suitable for the routine characterisation of chronic wounds in terms of their oxygen status, and correspondingly, their metabolically determining (and limiting) potential for healing and regeneration. The oxygen characteristic K-PO(2) can furthermore be used as a warning of impending ulceration, since the oxygen provision worsens over time prior to the demise of the ulcerated tissue, thus making a controlled prophylaxis possible.

Effect of Hand Position on EMG Activity of the Posterior Shoulder Musculature During a Horizontal Abduction Exercise.  

PubMed

Schoenfeld, B, Sonmez, RGT, Kolber, MJ, Contreras, B, Harris, R, and Ozen, S. Effect of hand position on EMG activity of the posterior shoulder musculature during a horizontal abduction exercise. J Strength Cond Res 27(10): 2644-2649, 2013-The reverse fly machine is a popular exercise for strengthening the horizontal shoulder abductors including the posterior deltoid. There seems to be little consensus as to which hand position most effectively targets the posterior deltoid despite this option on most machines. This study investigated the impact of varying one's hand position, and consequently altering shoulder joint rotation, on muscle activity in various glenohumeral muscles during exercise on the reverse fly machine. Nineteen resistance-trained men (mean age = 23.2 ± 4.3 years; height = 176.9 ± 7.1 centimeters; body mass = 81.3 ± 10.5 kilograms; body mass index = 25.9 ± 2.6) were recruited from a university population to participate in the study. In a repeated measures design, subjects grasped the hand bars on the machine with either a pronated (PRO) or neutral (NEU) grip and performed dynamic horizontal abduction repetitions to muscular failure using a load equating to approximately 75% body weight. The order of performance of the hand positions was counterbalanced between participants so that approximately half of the subjects performed PRO first and the other half performed NEU first. Surface electromyography was used to record both mean and peak muscle activity of the posterior deltoid, middle deltoid, and infraspinatus. Results showed that mean electromyography activity for the posterior deltoid was significantly greater in NEU compared with PRO (p = 0.046; 95% CI = 0.1-7.4% maximal voluntary isometric contraction). Similarly, mean electromyography activity of the infraspinatus also was significantly greater in NEU compared with PRO (p = 0.002; 95% CI = 3.7-13.6% maximal voluntary isometric contraction). The results of this study show that performing exercise on the reverse fly machine with a neutral hand position significantly increases activity of the posterior deltoid and infraspinatus muscles compared with a PRO hand position.

Role of the trochlear nerve in eye abduction and frontal vision of the red-eared slider turtle (Trachemys scripta elegans).  

PubMed

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

Quantitative MRI of Vastus Medialis, Vastus Lateralis and Gluteus Medius Muscle Workload after Squat Exercise: Comparison Between Squatting with Hip Adduction and Hip Abduction  

PubMed Central

The aim of the present study was to evaluate the use MRI to quantify the workload of gluteus medius (GM), vastus medialis (VM) and vastus lateralis (VL) muscles in different types of squat exercises. Fourteen female volunteers were evaluated, average age of 22 ± 2 years, sedentary, without clinical symptoms, and without history of previous lower limb injuries. Quantitative MRI was used to analyze VM, VL and GM muscles before and after squat exercise, squat associated with isometric hip adduction and squat associated with isometric hip abduction. Multi echo images were acquired to calculate the transversal relaxation times (T2) before and after exercise. Mixed Effects Model statistical analysis was used to compare images before and after the exercise (?T2) to normalize the variability between subjects. Imaging post processing was performed in Matlab software. GM muscle was the least active during the squat associated with isometric hip adduction and VM the least active during the squat associated with isometric hip abduction, while VL was the most active during squat associated with isometric hip adduction. Our data suggests that isometric hip adduction during the squat does not increase the workload of VM, but decreases the GM muscle workload. Squat associated with isometric hip abduction does not increase VL workload.

Cortico-muscular communication during the generation of static shoulder abduction torque in upper limb following stroke.  

PubMed

In this study, we introduced a new index, namely overlap index, to quantify the spatial resolution of cortical activity for muscle coordination based on the measurement of EEG-EMG coherence during a motor task. By applying this index on 4 control and 4 hemisphere chronic stroke subjects we successfully identified that there is a significantly increased overlap between biceps brachii at the elbow and intermediate deltoids at the shoulder when stroke subjects generating a static shoulder abduction torque. Muscles that have increased overlap in cortex are consistent with those that coactivate abnormally in stroke when compared to control subjects. These results not only proof the effectiveness of this index in quantifying the spatial resolution of cortical activity but also point out that the reduced spatial resolution of muscle activity in cortex can be a reason for the abnormal muscle coactivation observed in impaired arms following stroke. Quantification of the cortical overlap index will provide us with new tools to test for the modifiability of the nervous system following clinical interventions. This work will be an important step toward our long-term goal of developing more effective rehabilitation techniques for the treatment of stroke. PMID:17946799

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.

Relationships among performance of lateral cutting maneuver from lateral sliding and hip extension and abduction motions, ground reaction force, and body center of mass height.  

PubMed

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

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.

Anterior labrum reconstruction with mini-capsular shift procedure.  

PubMed Central

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

Diagnostic articulation tables  

NASA Astrophysics Data System (ADS)

In recent years, considerable progress has been made in the development of instrumental methods for general speech quality and intelligibility evaluation on the basis of modeling the auditory perception of speech and measuring the signal-to-noise ratio. Despite certain advantages (fast measurement procedures with a low labor consumption), these methods are not universal and, in essence, secondary, because they rely on the calibration based on subjective-statistical measurements. At the same time, some specific problems of speech quality evaluation, such as the diagnostics of the factors responsible for the deviation of the speech quality from standard (e.g., accent features of a speaker or individual voice distortions), can be solved by psycholinguistic methods. This paper considers different kinds of diagnostic articulation tables: tables of minimal pairs of monosyllabic words (DRT) based on the Jacobson differential features, tables consisting of multisyllabic quartets of Russian words (the choice method), and tables of incomplete monosyllables of the _VC/CV_ type (the supplementary note method). Comparative estimates of the tables are presented along with the recommendations concerning their application.

MITG test procedure and results  

SciTech Connect

Elements and modules for Radioisotope Thermoelectric Generator have been performance tested since the inception of the RTG program. These test articles seldom resembled flight hardware and often lacked adequate diagnostic instrumentation. Because of this, performance problems were not identified in the early stage of program development. The lack of test data in an unexpected area often hampered the development of a problem solution. A procedure for conducting the MITG Test was developed in an effort to obtain data in a systematic, unambiguous manner. This procedure required the development of extensive data acquisition software and test automation. The development of a facility to implement the test procedure, the facility hardware and software requirements, and the results of the MITG testing are the subject of this paper.

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.

Patient Radiation Doses in Interventional Cardiology Procedures  

PubMed Central

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

A systematic review of the diagnostic performance of orthopedic physical examination tests of the hip  

PubMed Central

Background Previous reviews of the diagnostic performances of physical tests of the hip in orthopedics have drawn limited conclusions because of the low to moderate quality of primary studies published in the literature. This systematic review aims to build on these reviews by assessing a broad range of hip pathologies, and employing a more selective approach to the inclusion of studies in order to accurately gauge diagnostic performance for the purposes of making recommendations for clinical practice and future research. It specifically identifies tests which demonstrate strong and moderate diagnostic performance. Methods A systematic search of Medline, Embase, Embase Classic and CINAHL was conducted to identify studies of hip tests. Our selection criteria included an analysis of internal and external validity. We reported diagnostic performance in terms of sensitivity, specificity, predictive values and likelihood ratios. Likelihood ratios were used to identify tests with strong and moderate diagnostic utility. Results Only a small proportion of tests reported in the literature have been assessed in methodologically valid primary studies. 16 studies were included in our review, producing 56 independent test-pathology combinations. Two tests demonstrated strong clinical utility, the patellar-pubic percussion test for excluding radiologically occult hip fractures (negative LR 0.05, 95% Confidence Interval [CI] 0.03-0.08) and the hip abduction sign for diagnosing sarcoglycanopathies in patients with known muscular dystrophies (positive LR 34.29, 95% CI 10.97-122.30). Fifteen tests demonstrated moderate diagnostic utility for diagnosing and/or excluding hip fractures, symptomatic osteoarthritis and loosening of components post-total hip arthroplasty. Conclusions We have identified a number of tests demonstrating strong and moderate diagnostic performance. These findings must be viewed with caution as there are concerns over the methodological quality of the primary studies from which we have extracted our data. Future studies should recruit larger, representative populations and allow for the construction of complete 2×2 contingency tables.

Diagnosing diagnostic error.  

PubMed

Diagnostic errors are the most common errors in primary care. Diagnostic errors have been found to be the leading cause of malpractice litigation, accounting for twice as many claims and settled cases as medication errors. Diagnostic error is common, harmful, costly, and very critical to the patient-safety issues in health care. Diagnostic errors have received relatively little attention, however. Of what is known, diagnostic errors are an important source of preventable harm. Focused research in this area is highly needed because the causes of diagnostic errors are subtle and solutions are less obvious than for other types of errors. As opposed to medication errors, where the factors predisposing to their occurrence and the resultant preventive strategies are better defined, the relationship between factors influencing the diagnostic reasoning or decision making and a diagnostic error are not as clear. This may include any failure in timely access to care; elicitation or interpretation of symptoms, signs, or laboratory results, formulation and weighing of differential diagnosis; and timely follow-up and specialty referral or evaluation. The literature reveals that diagnostic errors are often caused by the combination of cognitive errors and system failure. Increased understanding about diagnostic decision making, sources of errors, and applying some existing strategies into clinical practice would help clinicians reduce these types of errors and encourage more optimal diagnostic processes.

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.

Pleural procedures and pleuroscopy.  

PubMed

Pleural procedures are commonly performed by physicians from a range of specialities. These procedures vary in complexity, from relatively straightforward pleural aspiration to more challenging procedures such as pleuroscopy. After appropriate training, even complex pleural procedures have a low risk of complications. Nevertheless, an appreciation of procedural risks is essential for physician training and forms the crux of a valid patient consent process. This review presents a systematic evaluation of the potential complications of common pleural procedures. PMID:19703062

Chapter 7: Diagnostics  

NASA Astrophysics Data System (ADS)

In order to support the operation of ITER and the planned experimental programme an extensive set of plasma and first wall measurements will be required. The number and type of required measurements will be similar to those made on the present-day large tokamaks while the specification of the measurements—time and spatial resolutions, etc—will in some cases be more stringent. Many of the measurements will be used in the real time control of the plasma driving a requirement for very high reliability in the systems (diagnostics) that provide the measurements. The implementation of diagnostic systems on ITER is a substantial challenge. Because of the harsh environment (high levels of neutron and gamma fluxes, neutron heating, particle bombardment) diagnostic system selection and design has to cope with a range of phenomena not previously encountered in diagnostic design. Extensive design and R&D is needed to prepare the systems. In some cases the environmental difficulties are so severe that new diagnostic techniques are required. The starting point in the development of diagnostics for ITER is to define the measurement requirements and develop their justification. It is necessary to include all the plasma parameters needed to support the basic and advanced operation (including active control) of the device, machine protection and also those needed to support the physics programme. Once the requirements are defined, the appropriate (combination of) diagnostic techniques can be selected and their implementation onto the tokamak can be developed. The selected list of diagnostics is an important guideline for identifying dedicated research and development needs in the area of ITER diagnostics. This paper gives a comprehensive overview of recent progress in the field of ITER diagnostics with emphasis on the implementation issues. After a discussion of the measurement requirements for plasma parameters in ITER and their justifications, recent progress in the field of diagnostics to measure a selected set of plasma parameters is presented. The integration of the various diagnostic systems onto the ITER tokamak is described. Generic research and development in the field of irradiation effects on materials and environmental effects on first mirrors are briefly presented. The paper ends with an assessment of the measurement capability for ITER and a forward of what will be gained from operation of the various diagnostic systems on ITER in preparation for the machines that will follow ITER.

Cryptosporidiosis: multiattribute evaluation of six diagnostic methods.  

PubMed Central

Six diagnostic methods (Giemsa staining, Ziehl-Neelsen staining, auramine-rhodamine staining, Sheather's sugar flotation, an indirect immunofluorescence procedure, and a modified concentration-sugar flotation method) for the detection of Cryptosporidium spp. in stool specimens were compared on the following attributes: diagnostic yield, cost to perform each test, ease of handling, and ability to process large numbers of specimens for screening purposes by batching. A rank ordering from least desirable to most desirable was then established for each method by using the study attributes. The process of decision analysis with respect to the laboratory diagnosis of cryptosporidiosis is discussed through the application of multiattribute utility theory to the rank ordering of the study criteria. Within a specific health care setting, a diagnostic facility will be able to calculate its own utility scores for our study attributes. Multiattribute evaluation and analysis are potentially powerful tools in the allocation of resources in the laboratory.

Video integrated measurement system. [Diagnostic display devices  

SciTech Connect

A Video Integrated Measurement (VIM) System is described which incorporates the use of various noninvasive diagnostic procedures (moire contourography, electromyography, posturometry, infrared thermography, etc.), used individually or in combination, for the evaluation of neuromusculoskeletal and other disorders and their management with biofeedback and other therapeutic procedures. The system provides for measuring individual diagnostic and therapeutic modes, or multiple modes by split screen superimposition, of real time (actual) images of the patient and idealized (ideal-normal) models on a video monitor, along with analog and digital data, graphics, color, and other transduced symbolic information. It is concluded that this system provides an innovative and efficient method by which the therapist and patient can interact in biofeedback training/learning processes and holds considerable promise for more effective measurement and treatment of a wide variety of physical and behavioral disorders.

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.

In 1989, shortly after Westinghouse Hanford Company (WHC) assumed maintenance responsibilities for the Hanford site, a Department of Energy (DOE) maintenance audit found that field (working level) maintenance procedures and procedure practices of the facilities scattered across Hanford`s 560 square miles varied as greatly as the locations of those facilities. In some of the audited facilities there were few or no procedures; in others, procedures conflicted with or were redundant to procedures at other facilities. This document presents current efforts to centralize maintenance procedures.

The Diagnostic Accuracy of Dermoscopy for Scabies  

PubMed Central

Background Scabies is a contagious skin infestation characterized clinically by nocturnal pruritus, visible burrows and contagiousness. Dermoscopy has been suggested as an alternative for diagnosing scabies. But, there have been few well-designed studies evaluating the diagnostic accuracy of dermoscopy. Objective We tried to confirm the diagnostic accuracy of dermoscopy for diagnosing scabies. We also tried to demonstrate specific circumstances in which dermoscopic identification of mites ("with dermoscopy") is more useful in diagnosing scabies, and to identify the specific clinical findings that could be used as a possible marker in diagnosing scabies. Methods We compared the scraping procedure "with dermoscopy" and "without it" in 49 patients, measuring the duration and outcome of each procedure. Also, we tried to find the specific clinical factors associated with our objects. Results The skin scraping "with dermoscopy" was superior to "without it" with respect to the duration and accuracy of the procedure. A history of previous steroid treatment was associated with the superiority of dermoscopy. The correlation between the presence of visible burrows and the positive outcomes of "with dermoscopy" was statistically significant. Conclusion Skin scraping with dermoscopy is implicated as the diagnostic method of choice for scabies at the present time. Dermoscopy is especially useful in diagnosis of incognito scabies. In addition, the presence of visible burrows could be a reliable positive marker of scabies in the absence of dermoscopy or microscopy data.

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.

This is the final report of a three-year, Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). The purpose of this LDRD project was to develop new, inexpensive, simple electron beam bunch-length diagnostics with resolutions below 1/4 picosecond (ps). Our approach to this problem was three pronged. First, it was our intent to build a streak camera with 1/2 ps resolution. This conventional diagnostic was to be used to verify the results of two novel measurement techniques. Second, we wished to investigate the utility of off-axis coherent Smith-Purcell radiation as a bunch-length diagnostic. Finally, we planned to demonstrate a measurement of the electron bunch-length using a transversely deflecting RF field and a beam position monitor (BPM).

Interim analyses in diagnostic versus treatment studies: differences and similarities  

PubMed Central

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

Mycobacterium bovis isolation on bacteriological media from suspected cases of bovine tuberculosis (TB) demands laborious and time-consuming procedures. Even polymerase chain reaction (PCR) and radiometric analyses are secondary procedures and not alternatives to bacteriological procedures. Therefore, there is a need to develop new techniques aimed at rapid M. bovis detection in diagnostic samples. The human macrophage cell line THP-1 was

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.

Tele diagnostic by web  

NASA Astrophysics Data System (ADS)

Because of the development of multimedia technologies like Web and Internet, it now becomes possible to think about Tele Medicine and Tele Diagnostic for a distant place where no doctors and no nurses are situated at or are available. And also some kind of intelligence can be added onto them, which makes possible to give certain kind of medical treatment assistance or suggestions for a patient from a computer diagnostic base through the Internetworking. For doing this, here considers about a basic system of "Tele Diagnostic for a remote place" where it dose not have a doctor and a medical assistance. In order to implement the system, JAVA, VRML, HTML, and CORTONA are used as a basic language and a viewer. And also in order to add a kind of intelligence, Augmented Knowledge In Agent (AKIA) by using Back Propagation Neural Networks (BPNN) is used. And by this study, here can introduce the system that has the following basic mechanisms; By inputting physical data like temperature or blood pressure, the system would show a diagnostic assistance by TEXT. And also the bad place of body would be shown graphically if there were any. The system can be put onto Web, so that anybody could have this assistance at any place ubiquitously only if a person has Internetworking access.

Diagnostics for induction accelerators  

SciTech Connect

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

Although soft tissue stabilization procedures in the shoulder yield good results, arthroscopy and radiological investigations have identified more complex soft tissue and bony lesions that can be successfully treated using a Latarjet procedure. The authors have advanced this technique to make it possible arthroscopically, thereby conferring all the benefits that arthroscopic surgery offers. This article describes how and why the arthroscopic Latarjet procedure is a valuable tool in the treatment of complex shoulder instability and how the procedure can be introduced into practice. This technique has shown excellent results at short- to mid-term follow-up, with minimal complications. As such, this procedure is recommended to surgeons with good anatomic knowledge, advanced arthroscopic skills, and familiarity with the instrumentation. PMID:20497814

Requirements for ITER diagnostics  

SciTech Connect

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

ASSESSING THE USE OF A STANDARDIZED DENTAL DIAGNOSTIC TERMINOLOGY  

PubMed Central

Although standardized terminologies, such as the International Classification of Diseases (ICD), have been in use in medicine for over a century, in the dental profession, efforts to standardize dental diagnostic terms have not achieved widespread acceptance. To address this gap, a standardized dental diagnostic terminology - the ‘EZcodes’ terminology was developed in 2009. Fifteen dental practices and schools in the United States and Europe have implemented the ‘EZcodes’. In this paper we report on the utilization and valid entry of the EZcodes at three of the dental schools that have adopted this standardized dental diagnostic terminology. Electronic data on the use of procedure codes with diagnostic terms from the three schools over a one-year period between July 2010 and June 2011 were aggregated. The diagnostic term and procedure code pairs were adjudicated by three calibrated dentists. Analyses were conducted to gain insight into the utilization and valid entry of the EZcodes diagnostic terminology in the one-year period extending from 7/1/2010 through 6/30/2011. Error proportions in the entry of diagnostic term (and by diagnostic category) were also computed. Within the twelve-month period included in the analysis, a total of 29,965 diagnostic terms and 249,411 procedure codes were entered at the three institutions resulting in a utilization proportion of 12%. Caries and periodontics were the more frequently used categories. More than 1000 of the available 1321 diagnostic terms were never used at the three institutions. Overall, 60.5% of the EZcodes entries were found to be valid. In summary, our results demonstrate low utilization of EZ codes in an electronic dental record and raise the need for specific training of dental providers on the importance of using dental diagnostic terminology and specifically how to use the terms within the EHR. This will serve to increase the use/correct use of the EZcodes diagnostic terminology and ultimately create a reliable platform for undertaking clinical, outcomes and quality improvement-related research.

Barriers to clinical translation with diagnostic drugs.

Radioactive imaging agents, like diagnostic drugs generally, undergo a drug development process that parallels that of therapeutic agents, with similar development times but substantially lower development costs and substantially smaller postapproval markets. Although rapid advances in genetic and expression profiling are furthering the development of expensive pharmacotherapies targeted to small patient populations, the commercial development of imaging agents for small patient populations is blocked by the limited revenues available with current per-dose pricing and the relatively small numbers of imaging procedures that would be performed. A wide-ranging discussion on the best approaches to allow new diagnostic imaging agents to become part of the health-care system, and benefit the patient, is needed. PMID:23359658

Medial column procedures in the correction of adult acquired flatfoot deformity.  

PubMed

AAFD is a complex problem with a wide variety of treatment options. 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

Blast wave energy diagnostic  

NASA Astrophysics Data System (ADS)

The distance radiation waves that supersonically propagate in optically thick, diffusive media are energy sensitive. A blast wave can form in a material when the initially diffusive, supersonic radiation wave becomes transonic. Under specific conditions, the blast wave is visible with radiography as a density perturbation. [Peterson et al., Phys. Plasmas 13, 056901 (2006)] showed that the time-integrated drive energy can be measured using blast wave positions with uncertainties less than 10% at the Z Facility. In some cases, direct measurements of energy loss through diagnostic holes are not possible with bolometric and x-ray radiometric diagnostics. Thus, radiography of high compression blast waves can serve as a complementary technique that provides time-integrated energy loss through apertures. In this paper, we use blast waves to characterize the energy emerging through a 2.4 mm aperture and show experimental results in comparison to simulations.

ICF diagnostics. Revision 1  

SciTech Connect

In the past several years there have been significant advances and accomplishments in the field of Inertial Confinement Fusion (ICF) research which are directly attributable to an active experimental program supported by the development and applications of sophisticated and specialized diagnostics instruments and techniques. The continued development of high temporal-and spatial-resolution diagnostics, although with a somewhat different technical emphasis than previously, is essential for maintaining progress in ICF. With the generation of inertial fusion drivers now becoming available progress toward higher density compression of fusion fuel will be attained at the expense of temperature, and consequently emissions from the targets will be limited. At the same time since the targets are being driven to higher density they are more opaque to the low-to-moderate energy x-rays (up to a few keV) and particles (alpha particles, protons, and knock-on charged particles) that have been utilized for diagnosing target performance.

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.

Diagnostic upgrades on MTX  

NASA Astrophysics Data System (ADS)

The MTX experiment diagnostic capabilities have been recently upgraded with the addition of five new diagnostics. A second beamline was added on the existing Michelson ECE waveguide to accommodate the new polychromator. This provides four orders of magnitude higher time resolution (1-2 microsec) than the Michelson with an improved spectral resolution (5 GHz) using up to nine separate channels. A new four-channel ECE microwave receiver system using both an inside and outside hom placed on the inner tokamak wall allows us to measure the hot electron emission generated from gyrotron and FEL heating. A 15-channel interferometer on MTX has recently been upgraded with the addition of polarimetry to provide measurements of the poloidal magnetic field. This upgrade uses a new technique that determines the Faraday rotation by measuring the phase of a rapidly rotating polarization ellipse. The novel high-speed rotating optics (greater than 60 K rpm) used to produce this state of polarization is reviewed. A new two-channel O-mode reflectometer spanning 75-105 GHz is being added to measure the movements of the cutoff layer. By varying the frequency of this diagnostic, we are able to measure fluctuations deep within the plasma. Finally, a new particle probe diagnostic currently under construction will measure the FEL electric field strength inside the tokamak plasma. Here, we will inject a helium neutral beam into the center of the plasma and excite it with a high power excimer laser, thus, producing a Stark effect emission that is dependent on the FEL electric field strength.

Premedicating children for painful invasive procedures.  

PubMed

Children with cancer experience a great deal of anxiety concerning their treatment and invasive tests such as bone marrow aspirations (BMAs) and lumbar punctures (LPs). Responses of pain, fear, and anxiety are well documented and may cause regression, developmental delay, sleeping and eating problems, nausea and vomiting, nightmares, and depression. Diagnostic and treatment procedures need not cause such adverse effects if sufficient pharmacological sedation, analgesia, and anesthesia are used. However, studies show that inappropriate interventions such as underdosing and limited use of medications occur because of certain myths, beliefs, and lack of pharmacological knowledge on the part of health professionals. Studies that specifically address premedication for painful procedures in children with cancer have shown that only a small percentage of children receive premedications and that there is no clear consensus or standard for either drugs or dosages. The issue of premedicating children before procedures remains controversial and deserves further investigation. This study explored the attitudes and perceptions of oncology physicians and nurses concerning medicating children before procedures. Findings showed that most pediatric oncology specialists medicate their patients before invasive procedures and that the most common premedications used are Versed; Demerol, Phenergan, Thorazine; chloral hydrate; Ativan; fentanyl; Demerol; and Xylocaine. Most pediatric oncology specialists believe that premedication is necessary for children for BMAs and LPs. PMID:1492958

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 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

We report an advanced numerical procedure for deconvolution of theoretical asymmetric convolution integral of a Gaussian and a plasma broadened spectral line profile j(A,R)(lambda) for spectal lines. Our method determines all broadening parameters, self-consistently and directly from the line profile with minimal assumptions or prior knowledge. This method is useful for obtaining complete information on all plasma parameters directly from the recorded shape of a single line, which is very important in case no other diagnostic methods are available. The method is also convenient for determination of plasma parameters in the case of a symmetrical profile such as Voigt one. PMID:11308772

[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.

System-related factors contributing to diagnostic errors.  

PubMed

Several studies in primary care, internal medicine, and emergency departments show that rates of errors in test requests and result interpretations are unacceptably high and translate into missed, delayed, or erroneous diagnoses. Ineffective follow-up of diagnostic test results could lead to patient harm if appropriate therapeutic interventions are not delivered in a timely manner. The frequency of system-related factors that contribute directly to diagnostic errors depends on the types and sources of errors involved. Recent studies reveal that the errors and patient harm in the diagnostic testing loop have occurred mainly at the pre- and post-analytic phases, which are directed primarily by clinicians who may have limited expertise in the rapidly expanding field of clinical pathology. These errors may include inappropriate test requests, failure/delay in receiving results, and erroneous interpretation and application of test results to patient care. Efforts to address system-related factors often focus on technical errors in laboratory testing or failures in delivery of intended treatment. System-improvement strategies related to diagnostic errors tend to focus on technical aspects of laboratory medicine or delivery of treatment after completion of the diagnostic process. System failures and cognitive errors, more often than not, coexist and together contribute to the incidents of errors in diagnostic process and in laboratory testing. The use of highly structured hand-off procedures and pre-planned follow-up for any diagnostic test could improve efficiency and reliability of the follow-up process. Many feedback pathways should be established so that providers can learn if or when a diagnosis is changed. Patients can participate in the effort to reduce diagnostic errors. Providers should educate their patients about diagnostic probabilities and uncertainties. The patient-safety strategies focusing on the interface between diagnostic system and therapeutic intervention are strategies that involve both processes to facilitate appropriate follow-up and structural changes, such as the use of electronic tracking systems and patient navigation programs.

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.

Sports ability after Bankart procedure in professional athletes.  

PubMed

Recurrent anterior shoulder instability and the restoration of sports ability after surgery are common problems, especially among professional athletes. The purpose of this study was to evaluate the rate, level and time of returning to sports activity activity after Bankart procedure in anterior shoulder instability in high level athletes. From 1992-1994 61 patients suffering from recurrent anterior shoulder instability were operated on open Bankart procedure, 44 out of 61 were professional athletes. There were 7 handball, 7 basketball, 6 football, 2 waterpolo and 1 baseball player and 4 wrestlers, 2 weight-lifters, 2 boxers, 3 bicyclists, 2 motorists, 2 swimmers, 2 sailors, 2 kayakers and 2 skiers. The mean duration of instability was 19.1 months (3-72) before operation. 29 patients had posttraumatic recurrent anterior dislocation and 15 patients had posttraumatic anterior subluxations. The average number of redislocations was 4.4, ranging from 2 to 11. At the follow-up examination the patients were tested clinically for instability using the special score created by Walch and Duplay and the Constant functional score. We measured the strength of the rotator cuff by Kintrex isokinetic device from the 10th postoperative week. 35 out of 44 professional athletes could be followed-up. The average follow-up period was 14.2 months, from 6 to 31. 88% of the patients were able to return to sports participation, 66% on the previous level and 22% on a lower level. 12% of the patients finished their professional sports career. The mean rehabilitation period was 5.8 months, the average period of full restoration of sports ability was 9.3 months. Similar results were documented with the Constant score and the Walch-Duplay test (88% excellent or good, 12% fair). The main reason for the inability to continue sports activity was some pain during extreme abduction and external rotation of the arm and recurrent sensations of subluxation (3 cases). Based on the results of the follow-up examinations an early diagnosis is paramount followed by timely surgical intervention to restore anatomical integrity in proven cases of shoulder instability in professional athletes. The open Bankart procedure is preferred giving excellent functional results and providing good chances for the athletes to return to their previous sports level. PMID:8884733

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.

Cardiomyopathies (CM) are an important and heterogeneous group of diseases affecting the myocardium. They can induce mechanical and/or electrical disorders and are due to a variety of causes, they frequently are genetic. However, since their high number and their clinical complexity, the identification is still a challenge. Echocardiography is a very useful tool in the assessment of CM. In this review we aim to define the typical clinical features and to discuss the main diagnostic tool, above all echocardiography that can help physicians in the correct assessment of CM.

This paper, presented at the 2002 Physics Education Research Conference, describes the process of creating diagnostic assessments to assist teachers in formatively assessing their students. The process begins with the learning targets and ends with the creation of web-delivered sets of questions designed to diagnose students' facets of thinking. Early analysis from our first year of implementation indicates students are reading and thinking about the questions in their assignment. The researchers found that that, for certain topics, students' facets of thinking are highly context dependent.

Sprengel Deformity: Morphometric Assessment and Surgical Treatment by the Modified Green Procedure.  

PubMed

BACKGROUND:: We evaluated the pathologic anatomy of the Sprengel deformity using radiographs, 3-dimensional computed tomography (3D-CT), and magnetic resonance imaging (MRI), and reviewed our results of the modified Green procedure. METHODS:: Between 2002 and 2009, 23 scapulae in 22 patients were treated. The average age at the time of surgery was 3.4 years (range, 1.9 to 7.1 y). The outcome of surgery was assessed on the basis of changes in shoulder abduction and the radiographic findings using Cavendish classification, Rigault classification, scapular elevation, and medialization. Preoperative appearance was classified as grade III in 13 cases and grade IV in 10 cases according to the Cavendish classification, and as grade II in 4 cases and grade III in 19 cases according to the Rigault classification. Using 3D-CT, we assessed the height to width ratio on the scapular posterior view, the superior displacement ratio and rotational difference on the trunk posterior view, and the anterior curvature of the supraspinous portion on the scapular medial view. RESULTS:: The average follow-up postoperative period was 4.4 years (range, 2.2 to 8.7 y). Postoperatively, the shoulder abduction improved well, with a mean improvement of 63 degrees. Improvement of at least 1 Cavendish grade and 1 Rigault grade was attained in all cases. On preoperative 3D-CT, the mean height to width ratio of the affected scapula was significantly smaller than that of the contralateral scapula. There was an inverse relationship between the superior displacement ratio and the rotational difference. Anterior curvature of the supraspinous portion was seen in all cases. Omovertebral bone was found in 20 cases. MRI identified unossified omovertebral cartilage that was not evident by radiographs or CT. Transient brachial plexus palsy occurred in 2 patients, both of whom recovered within 4 months. Postoperative scapula winging and unsightly scarring were seen in 3 and 8 cases, respectively. CONCLUSIONS:: 3D-CT and MRI were helpful in evaluating the pathologic anatomy of the deformity and in planning the surgery. The modified Green procedure provided successful functional and cosmetic results. LEVEL OF EVIDENCE:: Level IV. PMID:23774200

This Technology Status Report describes research and accomplishments for the Instrumentation and Diagnostics (I D) Projects within the Advanced Research and Technology Development (AR TD) Program of the United States Department of Energy (DOE) Office of Fossil Energy (FE). Process understanding and control can be improved through the development of advanced instrumentation and diagnostics. The thrust of the I D Projects is to further develop existing measurement and control techniques for application to advanced coal-based technologies. Project highlights are: an inductively coupled plasma (ICP) instrument has been developed to analyze trace elements in gasification and combustion process streams. An in situ two-color Mie scattering technique with LSS can simultaneously measure the size, velocity, and elemental composition of coal particles during combustion. A high-temperature, fluorescence thermometry technique has accurately measured gas temperatures during field testing in combustion and gasification environments. Expert systems have been developed to improve the control of advanced coal-based processes. Capacitance flowmeters were developed to determine the mass flowrate, solid volume fraction, and particle velocities of coal slurries. 32 refs., 9 figs.

Magnetic Diagnostics for Ignitor  

NASA Astrophysics Data System (ADS)

All the electromagnetic diagnostics commonly used in present experiments to measure plasma parameters such as current, loop voltage, horizontal and vertical position, plasma beta, toroidal and poloidal modes, etc., are adopted for Ignitor. The moderate neutron fluence and very intense neutron flux expected in Ignitor demand the use of fully inorganic insulating materials, for which permanent radiation damage should be limited, but transient, reversible effects cannot be excluded. More data is needed to verify the sensitivity of the chosen materials to the radiation background, but in the meantime, an R&D program has started with the purpose of selecting insulator materials, testing impregnation techniques, verification of installation feasibility for all types of magnetic diagnostic coils. Full size prototypes are being manufactured. The magnetic coils system must be closely integrated with the plasma chamber as it requires early installation. While the initial positioning of the in-vessel components should be possible with relative ease (before the welding of the individual sectors of the plasma chamber), their replacement and maintenance in the course of the experimental life of the machine can be problematic. Therefore, an adequate level of redundancy is being considered.

MR imaging guidance for minimally invasive procedures  

NASA Astrophysics Data System (ADS)

Image guidance is one of the major challenges common to all minimally invasive procedures including biopsy, thermal ablation, endoscopy, and laparoscopy. This is essential for (1) identifying the target lesion, (2) planning the minimally invasive approach, and (3) monitoring the therapy as it progresses. MRI is an ideal imaging modality for this purpose, providing high soft tissue contrast and multiplanar imaging, capability with no ionizing radiation. An interventional/surgical MRI suite has been developed at Brigham and Women's Hospital which provides multiplanar imaging guidance during surgery, biopsy, and thermal ablation procedures. The 0.5T MRI system (General Electric Signa SP) features open vertical access, allowing intraoperative imaging to be performed. An integrated navigational system permits near real-time control of imaging planes, and provides interactive guidance for positioning various diagnostic and therapeutic probes. MR imaging can also be used to monitor cryotherapy as well as high temperature thermal ablation procedures sing RF, laser, microwave, or focused ultrasound. Design features of the interventional MRI system will be discussed, and techniques will be described for interactive image acquisition and tracking of interventional instruments. Applications for interactive and near-real-time imaging will be presented as well as examples of specific procedures performed using MRI guidance.

[Laparoscopic radical nephrectomy. Procedure, results, and complications].  

PubMed

Surgery is the treatment of choice for clear cell renal carcinoma not responding to chemotherapy, radiotherapy, or immunotherapy. The surgical procedure used has evolved over time in the past 40 years, mainly because of the development and widespread use of diagnostic procedures such as ultrasonography and CT. As a direct consequence, parenchymal-sparing surgery was no longer only used for patients with solitary kidneys and its indication started to be extended to patients with tumors up to 4 cm in diameter, in whom it has been shown to be a safe and effective alternative to radical nephrectomy. The other important milestone in development of renal cancer surgery undoubtedly was the revolution started in the 90s with advent of laparoscopic renal surgery, which has become established over the past 20 years approximately. Laparoscopic surgery initially raised concern about oncological safety, but clinical series with sufficiently long follow-up times and large sample sizes are now available to consider the laparoscopic approach as a reliable procedure. Technological development has caused the laparoscopic technique to be no longer seen as a procedure for the future, but rather as an absolutely current technique which should be implemented in most urology departments. Implementation of any new procedure usually involves a number of complications which we should be prepared to assume, while making every effort to try and prevent them. It is therefore essential to develop, and to implement using common sense, a training program on the procedure. Selection of patients and conditions to be treated is a crucial part of such a program.

Diagnostics development plan for ZR.  

SciTech Connect

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

[Aptamers in clinical diagnostics].  

PubMed

Aptamers are single-stranded DNA or RNA oligonucleotides selected in vitro from combinatorial libraries in a process called SELEX (Systematic Evolution of Ligands by EXponential Enrichment). Aptamers play a role of artificial nucleic acid ligands that can recognize and bind to various organic or inorganic target molecules with high specificity and affinity. They can discriminate even between closely related targets and can be easily chemically modified for radioactive, fluorescent and enzymatic labeling or biostability improvement. Aptamers can thus be considered as universal receptors that rival antibodies in diagnostics as a tool of molecular recognition. To date aptamers have been successively used instead of monoclonal antibodies in flow cytometry, immunochemical sandwich assays and in vivo imaging as well to detect wide range of small or large biomolecules.

Peritoneal tuberculosis: diagnostic options.  

PubMed Central

BACKGROUND: Extrapulmonary tuberculosis has vague symptoms and few signs. It is essential to recognize and diagnose this curable disease prior to performing definitive surgery. Newer tests such as DNA or RNA amplification allow for early diagnosis but have limitations. CASE: We report a case of peritoneal tuberculosis in an immigrant woman. She had vague symptoms of low-grade fever, mild abdominal pain, obstipation, and bloating. Diagnostic laparoscopy was performed to establish the diagnosis. Tuberculosis was confirmed by DNA extraction from the frozen section specimen with subsequent analysis using polymerase chain reaction. CONCLUSION: Peritoneal tuberculosis is a disease that often simulates malignancies. With the increasing prevalence of human immunodeficiency virus in developed countries, tuberculosis is also on the rise and should be considered in the differential diagnosis of a patient with an abdominal/pelvic mass and ascites.

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

[Diagnostics of endolymphatic hydrops].  

PubMed

The objective of the present work was to analyse the methods for diagnostics of endolymphatic hydrops associated with Miniere's disease most frequently employed in clinical practice using both the data from the world scientific literature and our own 25-30 year experience based on the observation of more than 500 patients. Camertonal studies of hearing acuity estimated from the results of air conduction measurements and relevant acoumetric curves were considered. The main methods of research are discussed including such as tonal threshold audiometry, ultrasound testing, loud sound lateralization, dehydration test, extratympanic electrocochleography, otoacoustic emission, and functional computed stabilometry. It is concluded that none of the above methods is as reliable as to yield the comprehensive information being sought. All the data obtained by the application of these techniques need to be supplemented by the medical history data, the patients' complaints, clinical signs and symptoms of the disease if the definitive diagnosis of endolymphatic hydrops is to be made.

Diagnostic criteria of dementia.  

PubMed

In the past two decades there has been a tremendous effort among clinicians and searchers to improve the diagnostic criteria of the dementias on the basis of the differential neurological and neuropsychological profiles. This was an obligatory requirement for clinical trials and the development of treatments. Over the years it became rapidly evident that the cohorts of patients in studies had some degree of heterogeneity, making it difficult to interpret the results of some studies, particularly in the vascular dementias and the mild cognitive impairment (MCI) group. For example, many sub-types of the vascular group were included in clinical trials, such as the cortical strokes, the lacunar states and the diffuse white matter disease cases, and some of the patients might have had also mixed pathology. In addition, the standard DSM IV criteria for dementia no longer represent our present knowledge of the clinical profile of some of the dementias such as vascular dementia (VaD) and fronto-temporal dementia where the memory impairment is not necessarily the first requirement. To improve the validity of clinical trials and eventually help developing more appropriate treatments, we revised the present diagnostic criteria and made recommendations for some changes in the context of the 2nd Canadian Conference on the Development of Antidementia Therapies, held in 2004 and reviewed in the light of the recent literature as of early 2006. It is expected that in the near future, these dementia criteria for clinical trials will have to be revised again in order to include specific subtypes of the dementias as well as biomarkers, structural and functional imaging.

Receiver operating characteristic analysis of eyewitness memory: comparing the diagnostic accuracy of simultaneous versus sequential lineups.  

PubMed

A police lineup presents a real-world signal-detection problem because there are two possible states of the world (the suspect is either innocent or guilty), some degree of information about the true state of the world is available (the eyewitness has some degree of memory for the perpetrator), and a decision is made (identifying the suspect or not). A similar state of affairs applies to diagnostic tests in medicine because, in a patient, the disease is either present or absent, a diagnostic test yields some degree of information about the true state of affairs, and a decision is made about the presence or absence of the disease. In medicine, receiver operating characteristic (ROC) analysis is the standard method for assessing diagnostic accuracy. By contrast, in the eyewitness memory literature, this powerful technique has never been used. Instead, researchers have attempted to assess the diagnostic performance of different lineup procedures using methods that cannot identify the better procedure (e.g., by computing a diagnosticity ratio). Here, we describe the basics of ROC analysis, explaining why it is needed and showing how to use it to measure the performance of different lineup procedures. To illustrate the unique advantages of this technique, we also report 3 ROC experiments that were designed to investigate the diagnostic accuracy of simultaneous versus sequential lineups. According to our findings, the sequential procedure appears to be inferior to the simultaneous procedure in discriminating between the presence versus absence of a guilty suspect in a lineup.

Automatic beamline calibration procedures  

SciTech Connect

Recent experience with the SLC and SPEAR accelerators have led to a well-defined set of procedures for calibration of the beamline model using the orbit fitting program, RESOLVE. Difference orbit analysis is used to calibrate quadrupole strengths, BPM sensitivities, corrector strengths, focusing effects from insertion devices, and to determine the source of dispersion and coupling errors. Absolute orbit analysis is used to locate quadrupole misalignments, BPM offsets, or beam loss. For light source applications, the photon beam source coordinates can be found. The result is an accurate model of the accelerator which can be used for machine control. In this paper, automatable beamline calibration procedures are outlined and illustrated with recent examples. 5 refs.

The objective was to asses the feasibility of the endoscopic technique for cochlear implant (CI) positioning avoiding mastoidectomy and to discuss the benefits and drawbacks of the technique. The study design is a surgical procedure description and prospective case series report. From December 2011 to October 2012, six patients underwent endoscopic CI. All cases were selected based on CT and MRI studies. All surgical steps were analyzed; intra-and post-operative complications were noted. The length of time for each surgical procedure was recorded. The surgical procedure was described step by step focusing on the anatomy of the round window (RW) niche, analyzing the critical point during the dissection. The timing of the surgical procedures was 120 ± 21 (mean ± SD) min. In 1/6 patients, intra-operative injury of the chorda tympani occurred. In all cases, an endoscopic identification was performed and the anatomical details of the RW niche were noted. In 6/6 cases, a RW niche magnification was performed endoscopically. 5/6 cases showed a normal conformation of the RW. In 1/6 patients, obliteration of the RW niche was found. In 4/6 patients, an endoscopic cochleostomy through the RW was performed. In 1/6 patients, a difficult insertion of the array was observed. The current follow-up is 7.3 months (SD ± 3.7). No post-operative short- or long-term complications were noted in this series. Endoscopic CI is a safe and viable technique with a low rate of complications and with good outcomes. PMID:23595616

Cost-Effectiveness Analysis of Diagnostic Options for Pneumocystis Pneumonia (PCP)  

PubMed Central

Background Diagnosis of Pneumocystis jirovecii pneumonia (PCP) is challenging, particularly in developing countries. Highly sensitive diagnostic methods are costly, while less expensive methods often lack sensitivity or specificity. Cost-effectiveness comparisons of the various diagnostic options have not been presented. Methods and Findings We compared cost-effectiveness, as measured by cost per life-years gained and proportion of patients successfully diagnosed and treated, of 33 PCP diagnostic options, involving combinations of specimen collection methods [oral washes, induced and expectorated sputum, and bronchoalveolar lavage (BAL)] and laboratory diagnostic procedures [various staining procedures or polymerase chain reactions (PCR)], or clinical diagnosis with chest x-ray alone. Our analyses were conducted from the perspective of the government payer among ambulatory, HIV-infected patients with symptoms of pneumonia presenting to HIV clinics and hospitals in South Africa. Costing data were obtained from the National Institutes of Communicable Diseases in South Africa. At 50% disease prevalence, diagnostic procedures involving expectorated sputum with any PCR method, or induced sputum with nested or real-time PCR, were all highly cost-effective, successfully treating 77–90% of patients at $26–51 per life-year gained. Procedures using BAL specimens were significantly more expensive without added benefit, successfully treating 68–90% of patients at costs of $189–232 per life-year gained. A relatively cost-effective diagnostic procedure that did not require PCR was Toluidine Blue O staining of induced sputum ($25 per life-year gained, successfully treating 68% of patients). Diagnosis using chest x-rays alone resulted in successful treatment of 77% of patients, though cost-effectiveness was reduced ($109 per life-year gained) compared with several molecular diagnostic options. Conclusions For diagnosis of PCP, use of PCR technologies, when combined with less-invasive patient specimens such as expectorated or induced sputum, represent more cost-effective options than any diagnostic procedure using BAL, or chest x-ray alone.

Beyond diagnostic accuracy: the clinical utility of diagnostic tests.  

PubMed

Like any other medical technology or intervention, diagnostic tests should be thoroughly evaluated before their introduction into daily practice. Increasingly, decision makers, physicians, and other users of diagnostic tests request more than simple measures of a test's analytical or technical performance and diagnostic accuracy; they would also like to see testing lead to health benefits. In this last article of our series, we introduce the notion of clinical utility, which expresses--preferably in a quantitative form--to what extent diagnostic testing improves health outcomes relative to the current best alternative, which could be some other form of testing or no testing at all. In most cases, diagnostic tests improve patient outcomes by providing information that can be used to identify patients who will benefit from helpful downstream management actions, such as effective treatment in individuals with positive test results and no treatment for those with negative results. We describe how comparative randomized clinical trials can be used to estimate clinical utility. We contrast the definition of clinical utility with that of the personal utility of tests and markers. We show how diagnostic accuracy can be linked to clinical utility through an appropriate definition of the target condition in diagnostic-accuracy studies. PMID:22730450

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.

Statistical quality control procedures.  

PubMed

The right quality control (QC) should ensure the detection of important errors. Statistical QC (SQC) should be included in all QC plans. The Clinical and Laboratory Standards Institute (CLSI) C24A3 provides guidance for the application of SQC in medical laboratories. It describes a QC planning process and provides an SQC selection tool that relates the sigma-metric of a testing process to the medically important systematic error and the rejection characteristics of different SQC procedures. Once the right SQC has been selected, the laboratory must implement SQC right. CLSI C24A3 also provides guidance for establishing run length and control limits. PMID:23331732

Moyamoya disease: Diagnostic imaging.  

PubMed

Moyamoya disease is a progressive vasculopathy leading to stenosis of the main intracranial arteries. The incidence of moyamoya disease is high in Asian countries; in Europe and North America, the prevalence of the disease is considerably lower. Clinically, the disease may be of ischaemic, haemorrhagic and epileptic type. Cognitive dysfunction and behavioral disturbance are atypical symptoms of moyamoya disease.Characteristic angiographic features of the disease include stenosis or occlusion of the arteries of the circle of Willis, as well as the development of collateral vasculature. Currently, magnetic resonance angiography and CT angiography with multi-row systems are the main imaging methods of diagnostics of the entire range of vascular changes in moyamoya disease.The most common surgical treatment combines the direct arterial anastomosis between the superficial temporal artery and middle cerebral, and the indirect synangiosis involving placement of vascularised tissue in the brain cortex, in order to promote neoangiogenesis. Due to progressive changes, correct and early diagnosis is of basic significance in selecting patients for surgery, which is the only effective treatment of the disease. An appropriate qualification to surgery should be based on a comprehensive angiographic and imaging evaluation of brain structures.Despite the rare occurrence of moyamoya disease in European population, it should be considered as one of causes of ischaemic or haemorrhagic strokes, especially in young patients.

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.

Interventional spinal procedures.  

PubMed

The interventional procedures for disk herniation and protrusion by percutaneous techniques are decompressive such as chemodiscolysis with chimopapain, nucleo-discectomy introduced by Onik, LASER discectomy, and recently nucleoplasty, and decompressive and direct antinflammatory such as chemiodiscolysis with an Oxygen-ozone mixture. These techniques have minimized the invasive nature of surgery and avoid or decrease complications like infection linked to surgery. Reducing intervertebral disc size by mechanical aspiration of a part of the disc or partially dissolving the herniation by drying reduces the conic pressure on the torn annulus and creates the space necessary for retropulsion whenever the circular fibres of the annulus regain a minimum capacity to contain the disc under tension. The proposed suggestion in these techniques is that a small change in volume produces large change in pressure. The success rates reported in different studies vary from 65 to 80% of excellent or good results with chemonucleolysis and aspiration. Vertebroplasty (VP) is done by percutaneous injection of acrylic cement (polymethylmetacrylate-PMMA) into the vertebrae under fluoroscopic and/or CT control to achieve an antalgic effect and stabilize the vertebral body. VP has been used for vertebral collapses caused by osteoporosis, long-term steroid treatment, aggressive symptomatic angiomas and lytic metastasis. The reported figures in literature are 80-95% of pain relief, within 7 days after procedure, commonly on the same day. PMID:15081127

[Symptomatic urinary tract infection of the female--diagnostics].  

PubMed

The basis for the diagnostic work-up of recurrent cystitis is formed by taking a precise medical history against the background of knowledge of the pathogenesis of urinary tract infections. The anamnesis should also focus on factors that influence the natural flora (sexual intercourse, hygiene) but additionally include preceding antibiotic treatment and diseases that affect the immune status (diabetes mellitus). Urinalysis is the principal examination among the laboratory diagnostic procedures. The diagnosis is promptly confirmed by immediate analysis of a clean catch midstream urine sample using a counting chamber or a test strip. As a matter of principle, microbiological diagnosis always ensues. Extended diagnostic work-up (urological staging) is aimed at detecting functional and anatomic abnormalities. While these factors only play a subordinate role during the premenopausal phase, they gain in importance during the postmenopausal phase. A key role is also attributed to local estrogen deficiency.

Rome I diagnostic criteria for IBS was published in 1992 and it became a global diagnostic criteria. However, the criteria was not practical and somewhat complicated. Moreover, its symptomatic duration was too long (defined as more than 3 months) to be introduced in clinical practice. Therefore, Japanese member of BMW(Bowel Motility Workshop) tried to develop a new diagnostic criteria for IBS and it was established in 1995 by way of the Delphi method. The criteria was named as BMW diagnostic criteria and it was shown below: BMW diagnostic criteria for IBS (1995) At least one month or more of repetitive symptoms of the following 1) and 2) and no evidence of organic disease that likely to explain the symptoms. 1) Existence of abdominal pain, abdominal discomfort or abdominal distension 2) Existence of abnormal bowel movement (diarrhea, constipation) Abnormal bowel movement includes at least one of the below; (1) Abnormal stool frequency (2) Abnormal stool form (lumpy/hard or loose/wartery stool) Moreover, the following test should be performed as a rule to exclude organic diseases. (1) Urinalysis, fecal occult blood testing, CBC, chemistry (2) Barium enema or colonofiberscopic examination The other diagnostic criteria for IBS was also reviewed and their characteristics were compared with BMW diagnostic criteria.

[Acute strong headache in emergency neurology (diagnostic and treatment)].  

PubMed

Acute, strong headache represent a frequent symptom with patients who report to the Emergency Neurology. Most of them have functional headaches from the group of primary headaches. However, a smaller number may have secondary headaches, due to structural changes of the cerebral parenchyma. Though the second group is considerably smaller, the secondary headaches, besides fast diagnostics require fast therapy, since they frequently imperil directly the patients life. The paper consider clinical and neurological predictions, indicating possible secondary headaches ("red flags") and diagnostic procedures, necessary to achieve their fast ethiological diagnosis. We consider also possibilities and limitations of certain additional methods (CT, cerebrospinal fluid examination, MR) with the aim to establish the examinations algorithm. Finally we offer procedures related to the therapy of acute primary as well as secondary strong headaches. PMID:15875472

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

The success of dusty plasmas is based on its unique diagnostic possibilities. The ability to follow the motion of any particle in a dusty plasma allows to explore the fundamental properties of strongly coupled systems at the kinetic level (see Chap. 7). This chapter gives an introduction to imaging diagnostics in dusty plasmas. In the first part, the basics of video microscopy are reviewed and the important role of a careful image analysis is stressed. The second part reports on recent developments on three-dimensional (3D) imaging techniques, that is, diagnostic systems which are able to track simultaneously all particles in a 3D dust cloud.

Diagnostics data management on MTX  

NASA Astrophysics Data System (ADS)

The Microwave Tokamak Experiment (MTX) is a magnetic fusion energy research experiment to explore electron cyclotron heating using a free electron laser operating in the microwave range. The diagnostic data from MTX is acquired and processed by a distributed, multivendor, computer network. Each shot of the experiment produces data files containing up to 15 megabytes of data. Typically half-second shots are taken every 5 minutes with 50 to 60 shots taken on a single day. As many as 80 full data shots have been taken on a good day. Data files are created on Hewlett-Packard (HP) computers running Unix, HP computers running BASIC, and a Digital Equipment Corporation (DEC) VAXcluster running VMS. A small portion of the data acquired on the HP systems is immediately stored in a data system on the VAXcluster, but most data is held and processed on the computer on which it was acquired. A commercial database program running on the VAXcluster maintains a history of the data files created for each shot. During the night, data files on all computers are compressed to about one-third their original size and the files on the HP computers are transferred to the VAXcluster. When enough data has accumulated, all data files that have not been previously archived are archived to 8 mm magnetic tape. Once the data is on the VAXcluster, a single defined procedure call may be used to obtain data that was taken on any of the computers in the network. Data that has been archived to tape is maintained on disk for a few days. Users may specify that certain shots be designated 'goodshots', whose data files will be maintained on disk for a longer period of time. If a user requests data for a shot that is no longer on disk, retrieval processes on the VAXcluster determine which tapes contain the data, request the computer operator to load the tapes if necessary, and retrieve the files from the tapes. The data is then available for processing by programs running on any computer in the network.

Comparison of diagnostic tests for infectious laryngotracheitis.  

PubMed

Diagnostic procedures for detection of infectious laryngotracheitis virus in tracheas of experimentally infected chickens, including the indirect fluorescent antibody test (IFAT), immunoperoxidase (IP), virus isolation (VI), histopathology, polymerase chain reaction (PCR), and DNA hybridization, were performed and compared. Using VI as a reference, we calculated the sensitivity and specificity of the tests. The sensitivities of IP, IFAT, histopathology, PCR, and hybridization were 100%, 93%, 7%, 27%, and 0%, respectively, and the specificities of IP, IFAT, histopathology, PCR, and hybridization were 93%, 93%, 100%, 100%, and 100%, respectively. Histopathology, PCR, and hybridization were more specific but lacked sensitivity compared to IP and IFAT. IP and IFAT were equally specific, but IP was more sensitive than IFAT. Based on these results, IP performed better than any other test. PMID:8790877

Quality assurance for diagnostic imaging equipment  

SciTech Connect

This report addresses factors that influence production of an image. It contains the necessary information to enable the imaging physician to report the diagnostic findings to the referring physician. Some of these factors are human, other are inherent to technique and equipment. The subject of the report is quality assurance, i.e., all of the management practices instituted by the imaging physician, to assure highest quality medical care, but an essential element of quality assurance is quality control. The first three sections are concerned with quality assurance in general and the remainder with quality control in specific circumstances. This report provides a systematic approach to procedures which can ensure that the physician and the imaging facility consistently achieve their optimal performance. This in turn, ensures that there is optimal use of radiation and that radiation exposures to patient and staff are maintained at a level consistent with the principles of optimization of radiation protection espoused by the NCRP.

Cerebrospinal fluid leakage--reliable diagnostic methods.  

PubMed

Prompt diagnosis and early treatment of cerebrospinal fluid (CSF) leakage minimizes the risk of severe complications. In patients presenting with clear fluid nasal discharge it is important to identify the nature of the rhinorrhea. The CSF leakage may occur as post-traumatic, iatrogenic, spontaneous or idiopathic rhinorrhea. The differential diagnosis of CSF rhinorrhea often presents a challenging problem. The confirmation of CSF rhinorrhea and localization of the leakage may be diagnosed by CT, MRI cisternography and MRI cisternography in combination with single photon emission tomography or radioisotopic imaging. Although these methods allow estimation of the CSF leakage with high accuracy, they are expensive and invasive procedures. Therefore, biochemical methods are still used in the differentiation. Although the most common diagnostic method for screening CSF leakage is glucose oxidase, its diagnostic sensitivity and specificity is generally unsatisfactory. False negative results may occur with bacterial contamination and false positive results are common in diabetic patients. Glucose detection is not recommended as a confirmatory test. As such, other biomarkers of the CSF leakage, such as beta-2-transferrin (beta-2 trf) and beta-trace protein (betaTP) are necessary to identify and confirm of this condition. PMID:21334321

MicrobPad MD: microbial pathogen diagnostic methods database.  

PubMed

Medical pathogens induce infections, illnesses and sometimes serious medical conditions in the infected hosts. Diagnosis of these pathogens is important for proper treatment and investigation of pathogenesis processes. Molecular techniques have been developed for facilitating accurate, sensitive and low-cost diagnosis of these pathogens. Based on these techniques, diagnostic devices have been developed for a number of pathogens. More devices are needed for comprehensive coverage of medical pathogens. To facilitate the development of these devices, a database with integrated information about diagnostic methods, targets, and primers/probes for the known bacterial, fungal and viral pathogens is needed. We developed the microbial pathogen diagnostic methods database MicrobPad MD (http://bidd.nus.edu.sg/group/MicrobPad/MicrobPad.asp or http://pha-bidd.nus.edu.sg/group/MicrobPad/MicrobPad.asp) to provide comprehensive information about the molecular diagnostic techniques, targets, primers/probes, detection procedures and conditions, and tested diagnostic accuracies and limit of diagnosis for 314 bacterial, fungal and viral species from 61 genera. While available, additional information such as pathogen strains and hosts, tissue distribution or habitats, cultivation methods, biochemical characteristics, virulence factors, morphology, diseases, symptoms, treatment and prevention methods are provided. Our Database covers 242 gene targets, 700 primers/probes, 340 virulence factors, and 261 diseases. Cross-links to the NCBI genome and SwissProt/UniProt databases are provided. PMID:23178820

Infectious endophthalmitis is a serious complication of intraocular surgery, perforating injury, or septic dissemination. Detection of the causative microorganisms is essential for effective treatment. Published positive culture rates vary from 24 to 95 %. To achieve a high positive rate of detection of microorganisms all material necessary to set up a culture has to be available in the operation theatre. Important is a variety of appropriate culture media: we use Columbia, Hematin, ENDO and yeast-cysteine blood plates as well as a nutrient solution. Samples may be brought into the culture media directly within the operation theatre. If no immediate transport to a specialised laboratory is possible, media may be cultured in the eye hospital under optimal conditions. Concurrently, undiluted samples should be used for eubacterial PCR. While standard PCR can only detect the causative microorganism, standard culture procedures provide additional information regarding resistance to anti-microbiologic therapies. In the case of presumed fungal endophthalmitis the collected vitrectomy fluid has to be centrifuged and thereafter cultured. In presumed endogenous endophthalmitis also extraocular samples should be examined (e. g., blood culture and smears from other sites of infection). With this approach a high detection rate can be achieved in patients with endophthalmitis. PMID:18236369

Diagnostic indices for vertiginous diseases  

PubMed Central

Background Vertigo and dizziness are symptoms which are reported frequently in clinical practice. We aimed to develop diagnostic indices for four prevalent vertiginous diseases: benign paroxysmal positional vertigo (BPPV), Menière's disease (MD), vestibular migraine (VM), and phobic postural vertigo (PPV). Methods Based on a detailed questionnaire handed out to consecutive patients presenting for the first time in our dizziness clinic we preselected a set of seven questions with desirable diagnostic properties when compared with the final diagnosis after medical workup. Using exact logistic regression analysis diagnostic scores, each comprising of four to six items that can simply be added up, were built for each of the four diagnoses. Results Of 193 patients 131 questionnaires were left after excluding those with missing consent or data. Applying the suggested cut-off points, sensitivity and specificity were 87.5 and 93.5% for BPPV, 100 and 87.4% for MD, 92.3 and 83.7% for VM, 73.7 and 84.1% for PPV, respectively. By changing the cut-off points sensitivity and specificity can be adjusted to meet diagnostic needs. Conclusions The diagnostic indices showed promising diagnostic properties. Once further validated, they could provide an ease to use and yet flexible tool for screening vertigo in clinical practice and epidemiological research.

The selective therapeutic apheresis procedures.  

PubMed

Selective apheresis procedures have been developed to target specific molecules, antibodies, or cellular elements in a variety of diseases. The advantage of the selective apheresis procedures over conventional therapeutic plasmapheresis is preservation of other essential plasma components such as albumin, immunoglobulins, and clotting factors. These procedures are more commonly employed in Europe and Japan, and few are available in the USA. Apheresis procedures discussed in this review include the various technologies available for low-density lipoprotein (LDL) apheresis, double filtration plasmapheresis (DFPP), cryofiltration, immunoadsorption procedures, adsorption resins that process plasma, extracorporeal photopheresis, and leukocyte apheresis.

Best practice guidelines for the use of next-generation sequencing applications in genome diagnostics: a national collaborative study of dutch genome diagnostic laboratories.  

PubMed

Next-generation sequencing (NGS) methods are being adopted by genome diagnostics laboratories worldwide. However, implementing NGS-based tests according to diagnostic standards is a challenge for individual laboratories. To facilitate the implementation of NGS in Dutch laboratories, the Dutch Society for Clinical Genetic Laboratory Diagnostics (VKGL) set up a working group in 2012. The results of their discussions are presented here. We provide best practice guidelines and criteria for implementing and validating NGS applications in a clinical setting. We introduce the concept of "diagnostic yield" as the main performance characteristic for evaluating diagnostic tests. We recommend that the laboratory procedures, including the tested genes, should be recorded in a publicly available document describing the complete "diagnostic routing." We also propose that laboratories should use a list of "core disease genes" for specific genetic diseases. This core list contains the essential genes for each disease, and they should all be included in a diagnostic test to establish a reliable and accurate molecular diagnosis. The guidelines will ensure a clear and standardized quality of care provided by genetic diagnostic laboratories. The best practice guidelines and criteria that are presented here were adopted by the VKGL in January 2013. PMID:23776008

Diagnostic efficacy of in vitro methods vs. skin testing in patients with inhalant allergies  

SciTech Connect

The purpose of our study was to investigate the diagnostic efficacy of two selected methods of in vitro allergy testing. Specifically, the PRIST/modified RAST I125 isotope systems and the Quantizyme/modified EAST alkaline phosphatase method were compared. The time, expense, convenience, and diagnostic efficacy of the two procedures are discussed. Special attention is given to the practicality of each method for the practicing physician.

MUSE optical alignment procedure  

NASA Astrophysics Data System (ADS)

MUSE (Multi Unit Spectroscopic Explorer) is a second generation VLT integral field spectrograph (1x1arcmin² Field of View) developed for the European Southern Observatory (ESO), operating in the visible wavelength range (0.465-0.93 ?m). A consortium of seven institutes is currently assembling and testing MUSE in the Integration Hall of the Observatoire de Lyon for the Preliminary Acceptance in Europe, scheduled for 2013. MUSE is composed of several subsystems which are under the responsibility of each institute. The Fore Optics derotates and anamorphoses the image at the focal plane. A Splitting and Relay Optics feed the 24 identical Integral Field Units (IFU), that are mounted within a large monolithic instrument mechanical structure. Each IFU incorporates an image slicer, a fully refractive spectrograph with VPH-grating and a detector system connected to a global vacuum and cryogenic system. During 2011, all MUSE subsystems were integrated, aligned and tested independently in each institute. After validations, the systems were shipped to the P.I. institute at Lyon and were assembled in the Integration Hall This paper describes the end-to-end optical alignment procedure of the MUSE instrument. The design strategy, mixing an optical alignment by manufacturing (plug and play approach) and few adjustments on key components, is presented. We depict the alignment method for identifying the optical axis using several references located in pupil and image planes. All tools required to perform the global alignment between each subsystem are described. The success of this alignment approach is demonstrated by the good results for the MUSE image quality. MUSE commissioning at the VLT (Very Large Telescope) is planned for 2013.

Laboratory procedures for the diagnosis of tuberculosis: a survey in ten Italian Regions.  

PubMed

The characteristics of laboratories performing tuberculosis (TB) diagnostic procedures were investigated in ten Italian Regions, through a mailed questionnaire. Three hundred and eighty laboratories answered (70.8 % response rate), 250 of which performed directly at least one TB diagnostic procedure. Standard criteria concerning microscopy, culture, identification, and drug susceptibility testing were frequently not satisfied, particularly those related to the volume of activity (32 % of laboratories performing microscopy examined 10 samples and 36 % of those performing culture performed 20 cultures per week), processing time, biosafety requirements and participation to internal/external quality control programs. The survey' results highlight the need to promote the adoption of standardized procedures and to centralize the mycobacteriology testing in a reduced number of high quality laboratories, in order to improve diagnostic accuracy, resource management and quality of surveillance data.
