    Cervical spine injuries are a common occurrence in multi-trauma patients and should be taken into account when planning further clinical management. This review describes in detail upper and lower cervical spine injuries and introduces the sub-axial injury classification (SLIC) that is based on three components: injury morphology, integrity of the discoligamentous complex and the neurologic status of the patient. If the total SLIC score is <3, non-surgical treatment is recommended. If the total is {>=}5, operative treatment is indicated as such a score is associated with instability and probably neurologic deficits. The precise diagnosis of the radiologist, which would include the SLIC classification, should facilitate clinical decision-making about further management. (orig.) [German] Halswirbelsaeulenverletzungen sind bei polytraumatisierten Patienten haeufig und sollten beim klinischen Management des Patienten beruecksichtigt werden. Verletzungen der oberen Halswirbelsaeule werden als Sonderformen eingeteilt. Die subaxialen Verletzungen koennen nach der SLIC-Klassifikation ('sub-axial injury classification') gescort werden, die auf der Morphologie der Verletzung, dem diskoligamentaeren Komplex und dem neurologischen Status basiert. Bei einem Score <3 wird ein konservatives Management empfohlen. Bei einem Score {>=}5 sollte eine operative Versorgung der Halswirbelsaeule vorgenommen werden, da die Verletzung eine Instabilitaet und moeglicherweise auch ein neurologisches Defizit verursacht. Anhand einer praezisen Diagnose des Radiologen unter Beruecksichtigung der SLIC-Klassifikation sollte dem Kliniker die Entscheidung fuer das weitere Management erleichtert werden. (orig.)

    Full Text Available Upregulation of heparanase has been reported in an increasing number of human cancer tissues. However, the level of salivary heparanase and its clinical significance in patients with salivary gland tumors remain unclear.Salivary heparanase levels in patients with salivary gland tumors were detected using enzyme-linked immunosorbent assays (ELISAs and the clinical significance was evaluated by analyzing the correlations among salivary heparanase levels, clinicopathological parameters, and clinical outcomes.The levels of salivary heparanase were significantly higher in patients with malignant salivary gland tumors than in benign tumors and normal controls (P<0.0001. High salivary heparanase levels were positively correlated with increased lymph node metastasis (P = 0.0235 and poorer tumor node metastasis stage (TNM (P = 0.0183. Survival analyses revealed that high salivary heparanase levels were associated with worse overall survival (P = 0.0023 and disease-free survival (DFS (P = 0.0025.The study shows that salivary heparanase levels, as detected by the ELISAs, can be used to diagnose and provide an accurate prognosis for malignant salivary gland tumors. Salivary heparanase level was an independent predictor in patients with malignant salivary gland tumors.

    Full Text Available Background/Aim. Graves disease (GD is defined as hyperthyroidism with diffuse goiter caused by immunogenic disturbances. Antibodies to the thyroid stimulating hormone (TSH receptors of thyroid gland (TRAb have crucial pathogenetic importance in the development and maintenance of autoimmune hyperthyroidism. The aim of this study was to identify sensitivity, specificity, positive an negative predictive value of TRAb level in sera of patients with GD as well as to estimate significance of TRAb level for remission and GD relapses occurrence. Methods. We studied prospectively and partly retrospectively 149 patients, 109 female and 40 male patients, 5-78 years old, in the period 1982-2007. There were 96 patients with GD. The control group consisted of 53 patients, 21 with hyperthyroidism of second etiology and 32 patients on amiodarone therapy, with or without thyroid dysfunction TRAb was measured by radioreceptor assay (TRAK Assay and DYNO Test TRAK Human Brahms Diagnostica GMBH. Results. According to the results the sensitivity (Sn of TRAb test was 80%, specificity (Sp 100%, positive predictive value (PP 100% and negative predictive value (NP 83%. Also, the Sn of hTRAb test was 94%, Sp 100%, PP 100% and NP 94%. Our results show that an increased level of TRAb/hTRAb at the beginning of the disease and the level at the end of medical therapy is associated with an increased number of GD relapses and a shorter remission duration. Conclusion. Detection and measurement of TRAb in serum is a very sensitive method for diagnosing GD and very highly specific in vitro method for differential diagnosis of various forms of hyperthyroidism. Clinical significance of differentiating various forms of hyperthyroidism, using this in vitro assay, lays in adequate therapeutic choice for these entities.

    Severe, recurrent or bilateral optic neuritis (ON) often falls within the neuromyelitis optica spectrum disorders (NMOSD), but the diagnosis can be particularly challenging and has important treatment implications. We report the features, course and outcomes of patients presenting with atypical ON when isolated at onset. We retrospectively analyzed 69 sequential patients referred to a single UK NMO center with isolated ON at onset. Aquaporin-4 antibody (AQP4-Ab) assessment was performed in all patients and IgG1 myelin-oligodenrocyte glycoprotein (MOG-Ab) in AQP4-Ab(neg) patients. 37 AQP4-Ab positive (AQP4-Ab(pos)) and 32 AQP4-Ab negative (AQP4-Ab(neg)) patients (8 with MOG-Ab) were identified. The AQP4-Ab(neg) group included heterogeneous diagnoses: multiple sclerosis (MS), NMO, relapsing isolated ON (RION), monophasic isolated ON and relapsing acute disseminated encephalomyelitis (ADEM)-like syndromes. Compared to AQP4-Ab(neg) patients, AQP4-Ab(pos) patients had a worse residual visual outcome from first attack (median VFSS 4 vs. 0, p = 0.010) and at last assessment (median VFSS 5 versus 2, p = 0.005). However, AQP4-Ab(neg) patients with RION also had poor visual outcome. Up to 35% of AQP4-Ab(neg) patients developed a LETM and two developed low positivity for AQP4-Ab over time. Eight AQP4-Ab(neg) patients (25%) were MOG-Ab positive, covering a range of phenotypes excluding MS; the first ON attack was often bilateral and most had relapsing disease with a poor final visual outcome [VFSS 4, range (0-6)]. In conlcusion, AQP4-Ab positivity is confirmed as a predictor of poor visual outcome but AQP4-Ab(neg) RION also had a poor visual outcome. Of those without AQP4-Ab, 25% had MOG-Ab and another 25% developed MS; thus, MOG-Ab is associated with AQP4-Ab(neg) non-MS ON.

    50 patients with a history of distortion injury of the cervical spine were examined with static and functional MRI. Functional MRI consisted of different patient`s positions from maximal extension to maximal flexion (30 , 0 , 25 , 40 , 50 ). T{sub 2}*-weighted gradient echo sequences were performed in a sagittal view for the different positions. Ligamentous instabilities and disc protrusions were seen only in functional MRI in 17 patients. These findings correlated with the neurological symptoms. Two patients were treated by operative fusion because of these findings. (orig.) [Deutsch] Bei 50 Patienten mit einem Schleudertrauma der Halswirbelsaeule wurden zu den statischen Magnetresonanztomogrammen der Halswirbelsaeule MR-Funktionsaufnahmen durchgefuehrt. Diese Funktionsaufnahmen erfolgten in 5 verschiedenen Flexionsgraden von maximaler Reklination bis zur maximalen Inklination (30 , 0 , 25 , 40 , 50 ). T{sub 2}*-gewichtete Gradienten-Echo-Sequenzen in sagittaler Schnittfuehrung wurden fuer jeden Flexionsgrad angefertigt. Bandinstabilitaeten und Bandscheibenvorwoelbungen konnten bei 17 Patienten nur in bestimmten Flexionsgraden erfasst werden. Diese 17 Patienten zeigten eine umschriebene neurologische Symptomatik, die von ihrer Lokalisation mit den in der MR-Funktionsdiagnostik erhobenen Befunden korrelierten. Zwei Patienten wurden aufgrund diese Befunde mit einer operativen Fusion therapiert. (orig.)

    An emergency decision support system for accidental releases of radioactivity into the atmosphere providing regional wind field information is presented. This system is based on intensive meteorological field campaigns each lasting 3-4 months in the regions around the Swiss nuclear power plants. The wind data from temporary and permanent stations are analysed to evaluate the typical wind field patterns occurring in these regions. A cluster analysis for these data-sets lead to 12 different wind field classes with a high separation quality. In the present report, it is demonstrated that an on-line acquisition of meteorological data from existing permanent stations is enough to diagnose the recent wind field class in a region with a radius of 25 km around the nuclear power station of Goesgen with a probability of 95% to hit the correct class. Furthermore, a method is presented to use a high resolution weather prediction model to forecast the future wind field classes. An average probability of 76% to hit the correct class for a forecast time of 24 hours is evaluated. Finally, a method for parameterization of turbulence providing input for dispersion models from standard meteorological online data is presented. (author)

    Acceleration injuries of the cervical spine are mostly caused by car accidents. Due to the high traffic density and the increasing number of car accidents with personal injuries the number of concerned persons is also increasing. A large percentage of injured persons suffer ongoing troubles following ineffective therapy trials up to occupational disability. Therefore the whiplash injury is a significant medical and legal problem. The book includes contributions of international experts on the latest state of research and the actual knowledge on the controversial discussed field. An interdisciplinary forum discusses medical, injury-mechanical, consultant-related and legal questions and therapeutic approaches that might be successful. [German] Beschleunigungsverletzungen der Halswirbelsaeule treten ueberwiegend nach Autounfaellen auf. Aufgrund der hohen Verkehrsdichte und der steigenden Anzahl an Verkehrsunfaellen mit Personenschaeden steigt auch die Zahl der Betroffenen stetig an. Einer grossen Zahl von Unfallgeschaedigten, die nach kurzer Zeit beschwerdefrei leben koennen, steht leider eine wachsende Zahl von Betroffenen mit anhaltenden Beschwerden, erfolglosen Therapieversuchen bis hin zur Berufsunfaehigkeit gegenueber. Das 'HWS-Schleudertrauma' stellt nach wie vor ein erhebliches medizinisches und rechtliches Problem dar. In diesem Buch beschreiben international ausgewiesene Experten den neuesten Forschungsstand, das aktuelle Wissen und die Lehrmeinungen auf diesem kontrovers diskutierten und komplexen Gebiet. In einem interdisziplinaeren Ansatz werden medizinische, verletzungsmechanische, gutachterliche und gerichtliche Fragestellungen diskutiert und Erfolg versprechende Therapieansaetze eroertert. Aerzte, Juristen, Versicherungen und Betroffene werden in einen gemeinsamen Dialog gebracht, mit dem Ziel, konstruktive Loesungen zu erarbeiten.

    In the framework of the project 'Windbank', wind field patterns in an area of 50 by 50 km{sup 2} in the Swiss Plateau around the nuclear power plant Muehleberg between the Alps and the Jura were measured with 22 temporary meteorological stations and 2 SODARs during four months in 1997. Hourly averages from this high resolution network were combined with meteorological information from routine stations and from a weather prediction model. This data-set comprises all available parameters influencing the complex wind flow in the investigated area between the Alps and the Jura. A cluster analysis for this data-set leads to 12 classes with a high separation quality. It is demonstrated, that an on-line acquisition of meteorological data from routine stations and from a weather prediction model can be used to diagnose the recent wind field class with a probability of 96 % to hit the correct wind field class. This diagnosis reveals wind fields with a very high spatial resolution in a very short time. Consequently, it is useful as a contribution to a decision support system for safety management after accidental releases of nuclear or chemical air pollutants. Further, a method is outlined to use the weather prediction model to forecast the wind field class. An average probability of 79 % to hit the correct wind field classes for a forecast time of up to 25 hours is evaluated.

    Angulated projections are standard in conventional radiography of the cervical spine, but rarely used in magnetic resonance imaging (MRI). As neuroforaminal pathology plays an important role in the etiology of radicular syndromes and may influence an operative approach, the utility of coronal oblique slices in MRI is explored. In a retrospective setting, 25 consecutive patients with neurologically diagnosed cervical monoradiculopathy were identified. T2-weighted sagittal, coronal oblique, and transversal slice orientations were anonymized. Two radiologists and two neurosurgeons independently assessed the cases. Criteria were site, cause, and grading of the neuroforaminal stenosis and the level of confidence on a 100-point visual analog scale (VAS). We computed interrater agreement, sensitivity, and t tests. Using only one slice orientation, the sensitivity in detecting the relevant neuroforamen was 0.40 for transversal, 0.68 for sagittal, and 0.64 for coronal oblique scans. A combination of the different angulations increased sensitivity and in 4 cases only the coronal oblique scans proved diagnostic. The readers felt significantly more confident in attributing the cause of the pathology on coronal oblique planes (a mean of 72 VAS points, p = 0.0003 vs 58 (sagittal) vs 64 (transversal)). Interrater agreement was significantly better for experienced (kappa 0. 48) than for inexperienced readers (0.32, p = 0.02). Adding coronal oblique planes in cervical spine MRI increases sensitivity and confidence in attributing the cause of neuroforaminal pathology. They are regarded as useful by all the readers. (orig.)

    Post-traumatic changes of the alar ligaments have been proposed to be the cause of chronic pain in patients after whiplash injury of the cervical spine. In addition to an asymmetric dens position, widening of the atlantodental distance to more than 12 mm can be an indirect sign of an alar ligament rupture. CT is recommended for detection of a avulsion fracture of the occipital condyle. Isolated ruptures of the alar ligaments are best visualized on MRI. In patients with chronic impairments after whiplash injuries changes of the alar ligaments on MRI must be differentiated from normal variants in healthy individuals. (orig.) [German] Posttraumatische Veraenderungen der Ligg. alaria werden als ursaechlich fuer chronische Beschwerden bei Patienten mit Beschleunigungsverletzungen der Halswirbelsaeule angesehen. Eine asymmetrische Densposition sowie eine Erweiterung der anterioren atlantoaxialen Distanz auf ueber 12 mm koennen auf konventionellen Roentgenaufnahmen ein indirektes Zeichen fuer das Vorliegen einer Fluegelbandverletzung sein. Die Computertomographie ist die Methode der Wahl zum Nachweis einer kondylaeren Ausrissfraktur des Lig. alare. Isolierte akute Bandverletzungen der Ligg. alaria sind hingegen in der MRT direkt nachweisbar. Bei Patienten mit chronischen Beschwerden nach Beschleunigungsverletzungen der Halswirbelsaeule muessen allerdings morphologische Auffaelligkeiten der Ligg. alaria im MRT von Normvarianten abgegrenzt werden.

Zuerst gelang es darzulegen, dass man imstande ist, durch die Bestimmung von Mg++ zusammen mit pH, Laktat und Leistungspunkten bei einem sportlichen Wettbewerb schon vor dem Bewerb anhand einer Mg++/pH-Korrelation die Chancen für anschließendes erfolgreiches Abschneiden vorherzusagen [1, 2]. Untersuchungen dieser Werte nach dem Bewerb gestatteten durch korrelative Analysen von Mg++-Veränderungen, Leistungspunkten und Laktatveränderungen einen tieferen Einblick in das Anstrengungs- Erfolgs-Verhältnis der Teilnehmer. Ähnlich den Resultaten beim Sport konnten durch Korrelation von Mg++ und diastolischem RR nach dem Test die signifikant-prognostischen Wirkungen der Mg++-Bestimmung gezeigt werden. Ähnlich wie beim Verhältnis zwischen Mg++ und Leistungspunkten zeigten auch hier diejenigen Patienten mit den geringsten Mg++-Abweichungen nach Provokation [1–3] auch die geringsten erregungsbedingten Veränderungen von diastolischem RR und Herzfrequenz durch den Test. Schließlich konnten wir bei 300 hypertonen Diabetikern zeigen, dass Blutzuckerveränderungen im Rahmen eines Glukoseprofils abhängig vom systolischen Blutdruck sind und eng mit Mg++-Veränderungen einhergehen, was einige neue Gedanken über den Mechanismus des Elektrolytverlusts bei Typ-2-Diabetikern und die Rolle des Blutdrucks bei Blutzuckerschwankungen zulässt [4–6].

    Purpose: We examined the postoperative changes of the cervical spine after treatment of cervical nerve root compression with anterior cervical discectomy and fusion with a new titanium intervertebral disc. Patients and Methods: 37 patients were examined prior to, as well as 4 days, 6 weeks, and 7 months after surgery. Lateral view X-rays and functional imaging were used to evaluate posture and mobility of the cervical spine, the position of the implants, and the reactions of adjacent bone structures. Results: Implantation of the titanium disc led to post-operative distraction of the intervertebral space and slight lordosis. Within the first 6 months a slight loss of distraction and re-kyphosis due to impression of the implants into the vertebral end-plates were found in all patients. We noted partial infractions into the vertebral end-plates in 10/42 segments and slight mobility of the implants in 14/42 segments. Both groups of patients showed reactive spondylosis and local symptoms due to loosening of the implants. The pain subsided after onset of bone bridging and stable fixation of the loosened discs. Conclusions: The titanium intervertebral disc provides initial distraction of the fusioned segments with partial recurrence of kyphosis during the subsequent course. Loosening of the implants with local symptoms can be evaluated with follow-up X-rays and functional imaging. (orig.) [German] Ziel: An Patienten mit zervikalen Kompressionssyndromen wurden Stellung und Funktion der Halswirbelsaeule nach Diskektomie und Fusion mit einem neuartigen Titaninterponat untersucht.

    Health care and information technology in health care is advancing at tremendous speed. We analysed whether the prognoses by Haux et al. - first presented in 2000 and published in 2002 - have been fulfilled in 2013 and which might be the reasons for match or mismatch. Twenty international experts in biomedical and health informatics met in May 2013 in a workshop to discuss match or mismatch of each of the 71 prognoses. After this meeting a web-based survey among workshop participants took place. Thirty-three prognoses were assessed matching; they reflect e.g. that there is good progress in storing patient data electronically in health care institutions. Twenty-three prognoses were assessed mismatching; they reflect e.g. that telemedicine and home monitoring as well as electronic exchange of patient data between institutions is not established as widespread as expected. Fifteen prognoses were assessed neither matching nor mismatching. ICT tools have considerably influenced health care in the last decade, but in many cases not as far as it was expected by Haux et al. in 2002. In most cases this is not a matter of the availability of technical solutions but of organizational and ethical issues. We need innovative and modern information system architectures which support multiple use of data for patient care as well as for research and reporting and which are able to integrate data from home monitoring into a patient centered health record. Since innovative technology is available the efficient and wide-spread use in health care has to be enabled by systematic information management.

    Abstract Pheochromocytoma and paraganglioma (PPG) are rare and late-diagnosed catecholamine secreting tumors, which may be associated with unrecognized and/or severe cardiomyopathies. We performed a computer-assisted systematic search of the electronic Medline databases using the MESH terms “myocarditis,” “myocardial infarction,” “Takotsubo,” “stress cardiomyopathy,” “cardiogenic shock”, or “dilated cardiomyopathy,” and “pheochromocytoma” or “paraganglioma” from 1961 to August 2012. All detailed case reports of cardiomyopathy due to a PPG, without coronary stenosis, and revealed by acute symptoms were included and analyzed. A total of 145 cases reports were collected (49 Takotsubo Cardiomyopathies [TTC] and 96 other Catecholamine Cardiomyopathies [CC]). At initial presentation, prevalence of high blood pressure (87.7%), chest pain (49.0%), headaches (47.6%), palpitations (46.9%), sweating (39.3%), and shock (51.0%) were comparable between CC and TTC. Acute pulmonary edema (58.3% vs 38.8%, P = 0.03) was more frequent in CC. There was no difference in proportion of patients with severe left ventricular systolic dysfunction (LV Ejection Fraction [LVEF] < 30%) at initial presentation between both groups (P = 0.15). LVEF recovery before (64.9% vs 40.8%, P = 0.005) and after surgical resection (97.7% vs73.3%, P = 0.001) was higher in the TTC group. Death occurred in 11 cases (7.6%). In multivariate analysis, only TTC was associated with a better LV recovery (0.15 [0.03–0.67], P = 0.03). Pheochromocytoma and paraganglioma can lead to different cardiomyopathies with the same brutal and life-threatening initial clinical presentation but with a different recovery rate. Diagnosis of unexplained dilated cardiomyopathy or TTC should lead clinicians to a specific search for PPG. PMID:26683930

    Purpose: To develop and evaluate a new, pneumatically operated motion apparatus for the dynamic functional MR examination of the cervical spine. Materials and Methods: A metal-free, pneumatically operated motion apparatus for functional dynamic MR imaging of the cervical spine was developed with respect to the geometry of a short-bore, superconducting high-field MR system. The examination protocol included a T{sub 2}-weighted multi-slice turbospin echo sequence (T{sub 2}-TSE, TR/TE=2610/115, matrix 254/512) and a dynamic T{sub 2}-weighted single-shot sequence (T{sub 2}-TSE, TR/TE=1110/110, matrix 255/256, acquisition time 1 s) in a sagittal plane. In order to evaluate the new motion apparatus and the examination protocol, 10 healthy subjects and 10 patients were examined. Results: The new motion apparatus allowed us to perform a passive stepless inclination and reclination motion of the patient's cervical spine within the MR scanner without leaving the magnet bore. The maximum motion degrees of the cervical spine were within -35 C (reclination) and 30 C (inclination). Due to the T{sub 2}-contrast and the high spatial resolution of the dynamic sequence, the myelon, the surrounding cerebrospinal fluid and the discoligamental structures were imaged with a good contrast and allowed a sufficient evaluation of the cervical spinal channel in all functional positions. Conclusions: This new motion apparatus allows a standardized and stepless dynamic functional MR examination is a short-bore high-field MR scanner. By the use of fast T{sub 2}-weighted spin echo sequences it has been shown to be of high value for the evaluation of the cervical myelon, the anterior and posterior cerebrospinal fluid and the discoligamental structures.

  7. Ribosomal protein S27-like in colorectal cancer: a candidate for predicting prognoses.

    Directory of Open Access Journals (Sweden)

    Chi-Jung Huang

    Full Text Available BACKGROUND: The development and progression of colorectal cancer (CRC involve a complex process of multiple genetic changes. Tumor suppressor p53 is capable of determining the fate of CRC cells. However, the role of a p53-inducible modulator, ribosomal protein S27-like (RPS27L, in CRC is unknown. METHODS: Here, the differential expression of RPS27L was examined in the feces and colonic tissues of CRC patients, to explore its possible correlation with patient survival and to investigate the cellular mechanisms underlying their clinical outcomes. Eighty intermediate-stage CRC patients (42 at stage II and 38 at stage III were divided into two groups according to their fecal RPS27L mRNA levels. The survival probabilities of the groups were estimated using the Kaplan-Meier method. The RPS27L protein in the colonic tissues of stage III patients with different prognoses was further examined immunohistochemically. RPS27L expression in LoVo cells was manipulated to examine the possible cellular responses in vitro. RESULTS: Elevated RPS27L expression, in either feces or tissues, was related to a better prognosis. In vitro, RPS27L-expressing LoVo cells ceased DNA synthesis and apoptotic activity while the expression of their DNA repair molecules was upregulated. CONCLUSIONS: Elevated RPS27L may improve the prognoses of certain CRC patients by enhancing the DNA repair capacity of their colonic cells, and can be determined in feces. By integrating clinical, molecular, and cellular data, our study demonstrates that fecal RPS27L may be a useful index for predicting prognoses and guiding personalized therapeutic strategies, especially in patients with intermediate-stage CRC.

    Mobile machinery consists of `special vehicles` as well as `off-road vehicles`. According to the Dutch Central Bureau of Statistics (CBS) special vehicles are converted (pick-up) trucks for a specific function, e.g. ambulances, garbage trucks and concrete mixers. Off-road vehicles do not have licence plates, but are self-propelling, are converted (pick-up) trucks for a specific function, e.g. ambulances, garbage trucks and concrete mixers. A model to calculate energy use of and emissions from mobile machinery is described for the period 1990-2020. In 1990 the calculated energy use of off-road vehicles is 28.6 PJ, amounting to 1.0% of the total energy use in the Netherlands. Agricultural machinery (9 PJ) has the largest share in this use, followed by special vehicles, excavators and fork-lift trucks. Emissions from mobile machinery are calculated for a great diversity of compounds using the model. The most important are CO2, CO, VOC, NOx and aerosols. The two CPB scenarios Global Shift and European Renaissance are used in order to make prognoses of energy use of and emissions from mobile machinery. Three policy options are assumed: no policy, a policy in which the actual emission standards are used, and a policy in which the standards are accentuated further for the year 2020. 70 refs.

    Although radiological features of pneumocystis pneumonia (PCP) in non-Acquired Immune Deficiency Syndrome (AIDS) immunocompromised patients have been reported by other authors, there were no studies on the radiological stages of PCP previously. This study aimed to elucidate the radiological stages and prognoses of PCP in non-AIDS immunocompromised patients. Retrospective analysis of radiological manifestations and prognoses of 105 non-AIDS PCP immunocompromised patients from August 2009 to April 2016 was conducted. Chest radiograph was divided into three stages: early stage (normal or nearly normal chest radiograph), mid stage (bilateral pulmonary infiltrates), and late stage (bilateral pulmonary consolidations); chest high-resolution computed tomography (HRCT) was also divided into three stages: early stage (bilateral diffuse ground-glass opacity [GGO]), mid stage (bilateral diffuse GGO and patchy consolidations), and late stage (bilateral diffuse consolidations). The case fatality rate (CFR) of all patients was 34.3% (36/105), all of them took routine chest X-ray (CXR), and 84 underwent chest CT examinations. According to the CXR most near the beginning of anti-PCP therapy, 18 cases were at early stage and CFR was 0 (0/18, P 0.05), and 37 cases were at late stage and CFR was 59.5% (22/37, P 0.05), 34 cases were at mid stage and CFR was 47.1% (16/34, P> 0.05), and 10 cases were at late stage and CFR was 80.0% (8/10, P< 0.05); barotrauma, including pneumothorax, pneumomediastinum, and pneumohypoderma, was found in 18 cases and the CFR was 77.8% (14/18, P< 0.01). Based on the radiological manifestations, the course of PCP in non-AIDS immunocompromised patients can be divided into three stages: early stage, mid stage, and late stage. The prognoses of patients treated at early stage are good, and those at late stage are poor. Furthermore, the CFR of patients with barotrauma is high.

    Out of 484 cases with breast conserving surgery between April 1989 and March 1999, surgical procedures of 34 cases were changed to total mastectomy due to positive surgical margins. In this study we evaluated a clinical significance of surgical margin in relation to clinicopathological factors and prognoses. Ninety-nine cases (20.5%) had positive margins that were judged when cancer cells existed within 5 mm from margin. In multivariate analysis of factors for surgical margin, EIC-comedo status, ly, located site, proliferative activity, and age were significant and independent factors. Regarding local recurrence, positive margin, age, ER and proliferative activity were significant factors in multivariate analysis, especially in cases not receiving postoperative radiation therapy. Radiation therapy may be beneficial for patients with positive surgical margin. And patients with breast recurrence alone had significantly higher survival rates. Therefore, it is suggested that surgical margin may not reflect survival, although it is a significant factor for local recurrence. (author)

    Purpose: To compare digital X-ray, CT, and MRI in the evaluation of ligamentous and osseous lesions in upper cervical spine specimens after artificial craniocervical injury with the findings of macroscopic preparation. Materials and Methods: A rotation trauma of defined severity was applied to 19 human corpses. After dissection of the neck specimens, digital X-ray (DIMA Soft P41, Feinfocus), conventional and helical CT (CTi, High Speed, GE, collimation 1 mm; pitch 1.0), and MRI were performed from the skull base to C3. The findings were correlated with the macroscopic results of preparation. MR (Magnetom Vision, Siemens) imaging was obtained with a 1.5 T system using 2D- and 3D-sequences. Results: Preparation revealed 6 fractures of the vertebral bodies, 5 fractures of the dens axis, 1 fracture of the arcus anterior of the atlas, 4 osseous flakes at the occipital condylus, and 6 lesions of the alar ligaments. Digital radiography showed all fractures and 4 osseous flakes at the occipital condylus. With conventional and helical CT, all fractures and all ruptured alar ligaments could be detected. 2D MRI depicted 9 of the fractures and 3D MRI showed fractures. With 2D MRI, 2 of the 4 osseous flakes at the condylus could be detected and with 3D MRI one occipital condylus fracture could be depicted. Ligamentous injuries were visualized by 2D MRI in 2 of 6 cases and by 3 D MRI inone case. Conclusions: In post-mortem studies, CT was superior to MRI in the visualization of osseous and ligamentous injuries after trauma of the upper cervical spine. However, these results are not transferable to patients with rotation injury in general. (orig.)

    Purpose: To study the time and mode of the development of the colliculus atlantis, the rate of its occurrence, the causes for its absence, and the radiological-clinical importance in the analysis of open-mouth-view radiographs. Material and Methods: Retrospective analysis of standardized radiographs of the cervical spine in more than 20 000 adults and 100 children. Study of 234 human skeletons of different ages and of 38 isolated adult atlases. Cadaveric dissection of 42 adults (age 48-87). Axial radiographs of isolated atlases and analysis of the bony structures of the colliculus atlantis. Results: The colliculus atlantis develops between age 10 and 13 years. It is always present after age 13 years. For the development of the colliculus atlantis a normal function of the craniocervical joints is necessary. In congenital dysmorphias of the craniocervical region with dysfunction of the craniocervical joints and in fractures of the dens axis before age 10 years with instable healing the colliculus atlantis is absent. Conclusions: The colliculus atlantis is developed at age 13 years apart from some rare exceptions as mentioned. Changes of the site and the structure of the colliculus atlantis allow an early diagnosis of certain traumatically and inflammatory diseases of this region. Furthermore, it serves as an additional parameter in functional analysis of the craniocervical joints. (orig.)

    Kinesin family protein 2A (KIF2A), an M-type nonmotile microtubule depolymerase, has attracted attention for its role in carcinogenesis and poor prognoses in various human cancers. In this study, we aimed to evaluate the expression of KIF2A and its robustness and potential to predict clinical outcomes in gastric cancer (GC) patients. The messenger RNA (mRNA) expression of KIF2A was determined in 24 pairs of cancerous and adjacent nontumor tissues by real-time polymerase chain reaction. Immunohistochemistry of KIF2A was performed on a tissue microarray composed of 461 GC and 65 matched adjacent nontumor tissues removed during surgeries and 18 chronic gastritis, 15 intestinal metaplasia, and 37 low-grade and 62 high-grade intraepithelial neoplasias acquired through gastric endoscopic biopsies. Univariate and multivariate Cox regression models were used to perform survival analyses. The high KIF2A expression was significantly correlated to histological type, TNM stage, and lymph node metastasis. A negative correlation was found between KIF2A expression and the 5-year survival rate of GC patients. In addition, multivariate analysis indicated that KIF2A is an independent prognostic factor in GC. This study demonstrated the high KIF2A expression might serve as an independent marker for poor prognoses in GC patients.

    Pheochromocytoma and paraganglioma (PPG) are rare and late-diagnosed catecholamine secreting tumors, which may be associated with unrecognized and/or severe cardiomyopathies. We performed a computer-assisted systematic search of the electronic Medline databases using the MESH terms "myocarditis," "myocardial infarction," "Takotsubo," "stress cardiomyopathy," "cardiogenic shock", or "dilated cardiomyopathy," and "pheochromocytoma" or "paraganglioma" from 1961 to August 2012. All detailed case reports of cardiomyopathy due to a PPG, without coronary stenosis, and revealed by acute symptoms were included and analyzed. A total of 145 cases reports were collected (49 Takotsubo Cardiomyopathies [TTC] and 96 other Catecholamine Cardiomyopathies [CC]). At initial presentation, prevalence of high blood pressure (87.7%), chest pain (49.0%), headaches (47.6%), palpitations (46.9%), sweating (39.3%), and shock (51.0%) were comparable between CC and TTC. Acute pulmonary edema (58.3% vs 38.8%, P = 0.03) was more frequent in CC. There was no difference in proportion of patients with severe left ventricular systolic dysfunction (LV Ejection Fraction [LVEF] < 30%) at initial presentation between both groups (P = 0.15). LVEF recovery before (64.9% vs 40.8%, P = 0.005) and after surgical resection (97.7% vs 73.3%, P = 0.001) was higher in the TTC group. Death occurred in 11 cases (7.6%). In multivariate analysis, only TTC was associated with a better LV recovery (0.15 [0.03-0.67], P = 0.03). Pheochromocytoma and paraganglioma can lead to different cardiomyopathies with the same brutal and life-threatening initial clinical presentation but with a different recovery rate. Diagnosis of unexplained dilated cardiomyopathy or TTC should lead clinicians to a specific search for PPG.

    In close collaboration with the government, Dutch greenhouse horticulture is developing its own settlement system for CO2 emissions, the so-called CO2 sector system. Such a system should have a total emission space for cultivation (excluding electricity sales). An agreement is being established between the sector and the Dutch government covering the total CO2 emission for the period 2013-2020 (including electricity sales), supplementing the Covenant on Clean and Efficient Agricultural Sectors. This quick scan offers a prognosis of the future CO2 emission of greenhouse horticulture [Dutch] De glastuinbouw ontwikkelt in nauwe samenwerking met de overheid een eigen vereveningssysteem voor CO2-emissie, het zogeheten CO2-sectorsysteem.

  12. Delusional infestations: case series, differential diagnoses, and management strategies.

    Science.gov (United States)

    Diaz, James H; Nesbitt, Lee T

    2014-01-01

    Physicians are not infrequently consulted by distraught patients with delusions of infestation who believe that they are infested with external or internal parasites and describe a crawling sensation of bugs or worms on or under their skin. Internet search engines were queried with the keywords as search terms to examine the latest articles on delusional infestations in order to describe presenting manifestations, differential diagnoses, and effective management strategies. The demographic and behavioral features of delusional infestations have remained constant and include: (1) onset in well-educated, middle-aged adults who are pet owners; (2) production of purported specimens of causative parasites; (3) pesticide overtreatment of themselves, their households, and pets; (4) excessive cleaning or vacuuming of households; (5) intense anger and resentment directed at physicians failing to confirm their self-diagnoses; and (6) sharing delusional symptoms with spouses or relatives. Although some reports have suggested that cases of delusional infestation are increasing today in the tropics, most studies have confirmed a stable incidence over time and similar disorder demographics worldwide. However, management strategies for delusional infestations have changed significantly over time with second generation, atypical antipsychotics offering safer adverse effect profiles and better prognoses than earlier therapies with first generation, typical antipsychotics. The most effective management strategies for delusional infestations include empathetic history-taking and active listening to the patient, careful exclusion of true parasitoses, and a therapeutic regimen that includes a second generation neuroleptic agent.

    The risk of recurrence following surgery in women with early breast cancer varies, depending upon prognostic factors. Adjuvant chemotherapy reduces this risk; however, increasingly effective regimens are associated with higher costs and toxicity profiles, making it likely that different regimens may be cost-effective for women with differing prognoses. To investigate this we performed a cost-effectiveness analysis of four treatment strategies: (1) no chemotherapy, (2) chemotherapy using cyclophosphamide, methotrexate, and fluorouracil (CMF) (a first generation regimen), (3) chemotherapy using Epirubicin-CMF (E-CMF) or fluorouracil, epirubicin, and cyclophosphamide (FEC60) (a second generation regimens), and (4) chemotherapy with FEC60 followed by docetaxel (FEC-D) (a third generation regimen). These adjuvant chemotherapy regimens were used in three large UK-led randomised controlled trials (RCTs). A Markov model was used to simulate the natural progression of early breast cancer and the impact of chemotherapy on modifying this process. The probability of a first recurrent event within the model was estimated for women with different prognostic risk profiles using a parametric regression-based survival model incorporating established prognostic factors. Other probabilities, treatment effects, costs and quality of life weights were estimated primarily using data from the three UK-led RCTs, a meta-analysis of all relevant RCTs, and other published literature. The model predicted the lifetime costs, quality adjusted life years (QALYs) and cost-effectiveness of the four strategies for women with differing prognoses. Sensitivity analyses investigated the impact of uncertain parameters and model assumptions. For women with an average to high risk of recurrence (based upon prognostic factors and any other adjuvant therapies received), FEC-D appeared most cost-effective assuming a threshold of £20,000 per QALY for the National Health Service (NHS). For younger low risk

    Coeliac disease is a common enteropathy characterized by an increased mortality mainly due to its complications. The natural history of complicated coeliac disease is characterised by two different types of course: patients with a new diagnosis of coeliac disease that do not improve despite a strict gluten-free diet (type A cases) and previously diagnosed coeliac patients that initially improved on a gluten-free diet but then relapsed despite a strict diet (type B cases). Our aim was to study the prognosis and survival of A and B cases. Clinical and laboratory data from coeliac patients who later developed complications (A and B cases) and sex- and age-matched coeliac patients who normally responded to a gluten-free diet (controls) were collected among 11 Italian centres. 87 cases and 136 controls were enrolled. Complications tended to occur rapidly after the diagnosis of coeliac disease and cumulative survival dropped in the first months after diagnosis of complicated coeliac disease. Thirty-seven cases died (30/59 in group A, 7/28 in group B). Type B cases presented an increased survival rate compared to A cases. Complicated coeliac disease is an extremely serious condition with a high mortality and a short survival. Survival depends on the type of natural history.

  7. Liability for Diagnosing Malingering.

    Science.gov (United States)

    Weiss, Kenneth J; Van Dell, Landon

    2017-09-01

    Malingering is a medical diagnosis, but not a psychiatric disorder. The label imputes that an evaluee has intentionally engaged in false behavior or statements. By diagnosing malingering, psychiatrists pass judgment on truthfulness. Evaluees taking exception to the label may claim that the professional has committed defamation of character (libel or slander) when the diagnosis is wrong and costs the claimant money or benefits. Clinicians may counter by claiming immunity or that the diagnosis was made in good faith. This problem has come into focus in military and veterans' contexts, where diagnoses become thresholds for benefits. Through historical and literary examples, case law, and military/veterans' claims of disability and entitlement, the authors examine the potency of the malingering label and the potential liability for professionals and institutions of making this diagnosis. © 2017 American Academy of Psychiatry and the Law.

    Abstract It is important to identify the severity of acute pancreatitis (AP) in the early course of the disease. Clinical scoring systems may be helpful to predict the prognosis of patients with early AP; however, few analysts have forecast the accuracy of scoring systems for the prognosis in hyperlipidemic acute pancreatitis (HLAP). The purpose of this study was to summarize the clinical characteristics of HLAP and compare the accuracy of conventional scoring systems in predicting the prognosis of HLAP. This study retrospectively analyzed all consecutively diagnosed AP patients between September 2008 and March 2014. We compared the clinical characteristics between HLAP and nonhyperlipidemic acute pancreatitis. The bedside index for severity of acute pancreatitis (BISAP), Ranson, computed tomography severity index (CTSI), and systemic inflammatory response syndrome (SIRS) scores were applied within 48 hours following admission. Of 909 AP patients, 129 (14.2%) had HLAP, 20 were classified as severe acute pancreatitis (SAP), 8 had pseudocysts, 9 had pancreatic necrosis, 30 had pleural effusions, 33 had SIRS, 14 had persistent organ failure, and there was 1 death. Among the HLAP patients, the area under curves for BISAP, Ranson, SIRS, and CTSI in predicting SAP were 0.905, 0.938, 0.812, and 0.834, 0.874, 0.726, 0.668, and 0.848 for local complications, and 0.904, 0.917, 0.758, and 0.849 for organ failure, respectively. HLAP patients were characterized by younger age at onset, higher recurrence rate, and being more prone to pancreatic necrosis, organ failure, and SAP. BISAP, Ranson, SIRS, and CTSI all have accuracy in predicting the prognosis of HLAP patients, but each has different strengths and weaknesses. PMID:26061329

    Papillary thyroid cancer (PTC) accounts for 80–90% of all thyroid malignancies. The tall cell variant (TCV) is a rare aggressive histotype of PTC. We performed a meta-analysis to compare the clinicopathological characteristics and prognostic factors of TCV with those of classical papillary thyroid carcinoma (cPTC). A literature search was performed using the PubMed and EMBASE databases using Medical Subject Headings and keywords. Twenty studies that included 1871 patients with TCV and 75323 patients with cPTC were included in our meta-analysis. Odds ratios and confidence intervals were calculated for each study. Patients with TCV were associated with multifocality, higher TNM stage, extrathyroidal extension, vascular invasion, lymph node metastasis, distant metastasis, BRAF mutation, disease-specific survival, and overall survival. We found that TCV cases were associated with more aggressive clinicopathological characteristics and poorer prognoses than cPTC cases were. Our results suggest that TCV is a high-risk PTC that warrants aggressive treatment and follow-up strategies. PMID:28009980

    2015-01-01

    Introduction Pain present 6 months following root canal treatment (RCT) may be either of odontogenic or nonodontogenic origin. This is importance because treatments and prognoses are different; therefore the aim of this study was to provide specific diagnoses of patients reporting pain 6 months after receiving initial orthograde RCT. Methods We enrolled patients from the Midwest region of an existing prospective observational study of pain after RCT. Pain at 6 months was defined as ≥1 day of pain and average pain intensity of at least 1/10 over the preceding month. An Endodontist and an Orofacial Pain practitioner independently performed clinical evaluations, which included periapical and cone-beam CT radiographs, to determine diagnoses. Results Thirty-eight out of the 354 eligible patients in the geographic area (11%) met the pain criteria, with 19 (50%) consenting to be clinically evaluated. As the sole reason for pain, 7 patients (37%) were given odontogenic diagnoses (4 involving the RCT tooth, 3 involving an adjacent tooth). Eight patients (42%) were given nonodontogenic pain diagnoses (7 from referred temporomandibular disorder (TMD) pain, 1 from persistent dentoalveolar pain disorder (PDAP)). Two patients (11%) had both odontogenic and nonodontogenic diagnoses, while 2 (11%) no longer fit the pain criteria at the time of the clinical evaluation. Conclusion Patients reporting “tooth” pain 6 months following RCT had a nonodontogenic pain diagnosis accounting for some of this pain, with TMD being the most frequent nonodonotgenic diagnosis. Dentists should have the necessary knowledge to differentiate between these diagnoses to adequately manage their patients. PMID:25732400

    Full Text Available Today, most survivors after cardiac arrest will receive a targeted temperature management in the post-resuscitation phase. Early the important question of the neurological prognosis occurs. In addition to the neurological examination (motor response to painful stimuli, brain stem reflexes technical diagnostics are widely used (SEP, EEG, CCT, CMRI. Furthermore, the serum concentration of biomarkers, such as neuron-specific Enolase (NSE in clinical routine and others mainly in the context of research (S-100B, CRP, PCT, micro-RNA are determined. After introduction of targeted temperature management, several studies from different centres have re-evaluated prognostic parameters. Hypothermia likely alters the level of neuron-specific enolase, markedly higher cut-offs apply for patients treated with hypothermia. The prognostic value of median nerve SEP remains largely unchanged. The sedation used during hypothermia renders neurological examination unreliable, even a few days after rewarming the lack of a motor response to painful stimuli does not safely exclude good neurological outcome. In addition, the absence of corneal reflexes is a less reliable parameter than the absence of pupillary light response. Recent studies indicate that evaluation of several prognostic parameters and interpretation in synopsis is advisable. In addition, clinical follow-up over a few days and re-evaluation of prognostic parameters may increase safety of a poor outcome prediction. p bKurzfassung: /bAktuell wird die Mehrzahl der Patienten nach erfolgreicher Reanimation mit einem „Targeted Temperature Management“ in der Post-Reanimationsphase behandelt.

  18. Diagnosing oceanic nutrient deficiency

    Science.gov (United States)

    Moore, C. Mark

    2016-11-01

    The supply of a range of nutrient elements to surface waters is an important driver of oceanic production and the subsequent linked cycling of the nutrients and carbon. Relative deficiencies of different nutrients with respect to biological requirements, within both surface and internal water masses, can be both a key indicator and driver of the potential for these nutrients to become limiting for the production of new organic material in the upper ocean. The availability of high-quality, full-depth and global-scale datasets on the concentrations of a wide range of both macro- and micro-nutrients produced through the international GEOTRACES programme provides the potential for estimation of multi-element deficiencies at unprecedented scales. Resultant coherent large-scale patterns in diagnosed deficiency can be linked to the interacting physical-chemical-biological processes which drive upper ocean nutrient biogeochemistry. Calculations of ranked deficiencies across multiple elements further highlight important remaining uncertainties in the stoichiometric plasticity of nutrient ratios within oceanic microbial systems and caveats with regards to linkages to upper ocean nutrient limitation. This article is part of the themed issue 'Biological and climatic impacts of ocean trace element chemistry'.

    Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is an autosomal recessive lysosomal storage disorder resulting from a deficiency of N-acetylgalactosamine-6-sulfate sulfatase (GALNS) activity. Diagnosis can be challenging and requires agreement of clinical, radiographic, and laboratory findings. A group of biochemical genetics laboratory directors and clinicians involved in the diagnosis of MPS IVA, convened by BioMarin Pharmaceutical Inc., met to develop recommendations for diagnosis. The following conclusions were reached. Due to the wide variation and subtleties of radiographic findings, imaging of multiple body regions is recommended. Urinary glycosaminoglycan analysis is particularly problematic for MPS IVA and it is strongly recommended to proceed to enzyme activity testing even if urine appears normal when there is clinical suspicion of MPS IVA. Enzyme activity testing of GALNS is essential in diagnosing MPS IVA. Additional analyses to confirm sample integrity and rule out MPS IVB, multiple sulfatase deficiency, and mucolipidoses types II/III are critical as part of enzyme activity testing. Leukocytes or cultured dermal fibroblasts are strongly recommended for enzyme activity testing to confirm screening results. Molecular testing may also be used to confirm the diagnosis in many patients. However, two known or probable causative mutations may not be identified in all cases of MPS IVA. A diagnostic testing algorithm is presented which attempts to streamline this complex testing process.

    Recently, a genetic marker (IL-1 genotype) that identifies individuals at higher risk for developing severe periodontal disease was discovered. A subgroup of the population reported on earlier was evaluated to determine if knowledge of the patient's IL-1 genotype would improve accuracy in assignment of prognoses and prediction of tooth loss. This subgroup consisted of 42 patients (1,044 teeth) in maintenance care for 14 years; 16 tested IL-1 genotype-positive (IL-1GP). Nine were smokers, and 30 had a history of smoking, with an average of 29.44 pack years. A multiple Cox regression model and Kaplan-Meier survival plots were fit to the subset of patients to evaluate tooth loss. Both IL-1GP and heavy smoking were significantly related to tooth loss. A positive IL-1 genotype increased the risk of tooth loss by 2.7 times, and heavy smoking by 2.9 times. The combined effect of IL-1GP and heavy smoking increased the risk of tooth loss by 7.7 times. The value of clinical parameters traditionally used to assign prognosis was found to be dependent on IL-genotype and smoking status. In the model that included IL-1 genotype and heavy smoking, none of the clinical parameters added significantly to the model for tooth loss while mobility, probing depth, crown-to-root ratio, and percent bone loss added significantly to the model, which included IL-1 genotype in non-smokers. IL-1GP patients and patients who smoked heavily demonstrated a much worse tooth survival rate when compared to IL-1 genotype-negative patients and non-smokers, respectively. Knowledge of the patient's IL-1 genotype and smoking status will improve the clinician's ability to accurately assign prognosis and predict tooth survival. Clinical implications are as follows. Investigators were unable to judge which patients would be IL-GP or negative based on their clinical presentation or family history of tooth loss due to periodontal disease. Since periodontal diseases are multifactorial, knowledge of the patient

  1. A Case of Intestinal Obstruction in Pregnancy Diagnosed by MRI and Treated by Intravenous Hyperalimentation

    Full Text Available Intestinal obstruction in pregnancy is rare and is mainly caused by prior pelvic surgery. We herein report a case of intestinal obstruction in a pregnant female with a history of laparoscopic myomectomy, who presented with hypogastric pain, abdominal distension, and vomiting at 26 weeks of gestation. A simple intestinal obstruction was diagnosed by MRI. Conservative treatments, including intravenous hyperalimentation and the placement of an ileus tube, were provided and her abdominal symptoms improved for 14 days. After restarting oral intake, she had no abdominal symptoms. She gave birth to a 2,146 g female infant by caesarean section at 37 weeks and 1 day of gestation. Although an area of cicatrization, which was thought to have been the starting point of the occlusion that caused the intestinal obstruction, was found, the excision of the small intestine was not necessary. Her postoperative course was uneventful. Intestinal obstruction requires a prompt diagnosis and aggressive intervention may be necessary to minimize the morbidity and mortality associated with this rare complication of pregnancy. MRI can be safely used during pregnancy to diagnose intestinal obstruction and intravenous hyperalimentation may improve the maternal and fetal prognoses.

    Objective To explore the factors related to the prognoses in patients with recurrent multiple glioblastomas. Methods Of 106 patients with recurrent multiple glioblastomas, who underwent surgical resection of the tumors from January, 2005 to December, 2012 in our hospital, and were followed up, 78 suffered from solitary lesion and 28 from multiple lesions. Each patient with multiple tumors was matched with a patient with a solitary glioblastoma on the basis of age, gender, tumorous location, extent of resection, postoperative radiotherapy or chemiotherapy and Karnofsky Performance Scale (KPS) score and then case-control study was performed. The patients’survival time was analyzed by Kaplan-Meier cure and log-rank tests. Results Long-rank test showed that median overall survival time (8.5 months) was significant longer in the patients with solitary glioblastoma than that (4.5 months) in the patients with multiple glioblastomas (P<0.05). The median overall survival time (7.9 months) was significantly longer in the patients with multiple glioblastomas which were totally resected than that (3.6 months) in the patients with multiple glioblastomas which were partially resected (P<0.05). Conclusions It is suggested the prognosis in the patient with multiple glioblastomas is significantly worse than that in patient with solitary glioblastoma. And the more tumor is resected, the better the prognosis will be in the patients with multiple glioblastomas, in who the tumor should be resected totally as possible on the basis of protecting important cerebral function.%目的:探讨复发性多发胶质母细胞瘤(GBM)预后的影响因素。方法2005年1月至2012年12月手术切除并获得完整随访的复发性GBM 106例,其中单发78例,多发28例(多发组);根据患者年龄、性别、肿瘤部位、手术切除程度、术后是否放化疗、术前KPS评分从单发GBM中选取与多发GBM相匹配的病例28例作为对照(单发组);多发

    Pain present 6 months after root canal treatment (RCT) may be of odontogenic or nonodontogenic origin. This is important because treatments and prognoses are different; therefore, the aim of this study was to provide specific diagnoses of patients reporting pain 6 months after receiving initial orthograde RCT. We enrolled patients from the Midwest region of an existing prospective observational study of pain after RCT. Pain at 6 months was defined as ≥1 day of pain and average pain intensity of at least 1 of 10 over the preceding month. An endodontist and an orofacial pain practitioner independently performed clinical evaluations, which included periapical and cone-beam computed tomographic radiographs, to determine diagnoses. Thirty-eight of the 354 eligible patients in the geographic area (11%) met the pain criteria, with 19 (50%) consenting to be clinically evaluated. As the sole reason for pain, 7 patients (37%) were given odontogenic diagnoses (4 involving the RCT tooth and 3 involving an adjacent tooth). Eight patients (42%) were given nonodontogenic pain diagnoses (7 from referred temporomandibular disorder pain and 1 from persistent dentoalveolar pain disorder). Two patients (11%) had both odontogenic and nonodontogenic diagnoses, whereas 2 (11%) no longer fit the pain criteria at the time of the clinical evaluation. Patients reporting "tooth" pain 6 months after RCT had a nonodontogenic pain diagnosis accounting for some of this pain, with temporomandibular disorder being the most frequent nonodontogenic diagnosis. Dentists should have the necessary knowledge to differentiate between these diagnoses to adequately manage their patients. Copyright © 2015 American Association of Endodontists.

    Full Text Available This study aimed to identify nursing diagnoses in overweight adolescents from public schools, according to the International Classification for Nursing Practice. A population-based cross-sectional study that investigated the socio-demographic, behavioural and psychological characteristics of adolescents aged from 10 to 14 years. 11 nursing diagnoses were identified: "Risk of overweight", "Risk of impaired adolescent development", "Risk of insecurity in parental role performance", "Risk of the family impaired ability to manage diet regime", "Risk of impaired ability to manage diet regime", "Risk of lack of knowledge of dietary regime", "Risk of excess food intake", "Risk of negative self-image", "Risk of low self-esteem", "Risk of impaired social well-being" and "Impaired exercise pattern". These diagnoses reflect the multifactorial nature of obesity, highlighting the need for interdisciplinary and intersectoral articulation of nursing interventions for prevention and control of overweight.

  13. Challenges in diagnosing hepatic encephalopathy.

    Weissenborn, K

    2015-02-01

    The term "hepatic encephalopathy" (HE) covers the neuropsychiatric syndrome associated with acute, chronic and acute-on-chronic liver disease (CLD). This paper deals with clinical features and diagnosis of HE in patients with liver cirrhosis and portal hypertension or porto-systemic shunts. The possible impact of concomitant disorders and the cirrhosis underlying liver disease upon brain function is described emphasizing the need of a detailed diagnostic work up of every individual case before diagnosing HE. Currently used methods for diagnosing minimal or covert hepatic encephalopathy are compared with regard to their sensitivity and specificity for diagnosing HE against the background of a multitude of concomitant disorders and diseases that could contribute to brain dysfunction.

  16. The birth of schizophrenia or a very modern Bleuler: a close reading of Eugen Bleuler's 'Die Prognose der Dementia praecox' and a re-consideration of his contribution to psychiatry.

    2014-12-01

    After Eugen Bleuler introduced 'schizophrenia' in 1908, the term was hotly debated but eventually led to the abandonment of Kraepelin's previous term 'dementia praecox'. Bleuler's contribution has subsequently been interpreted in two main ways. One tradition holds that Bleuler merely renamed 'dementia praecox' while conceptually continuing the Kraepelinian tradition. The other, focusing on Bleuler's characterization of 'dementia praecox' in terms of specific psychological alterations, accredits him with a genuine re-conceptualization. Based on a close reading of 'Die Prognose der Dementia praecox', the paper in which Bleuler first mentioned 'schizophrenia', we suggest a further interpretation of Bleuler's contribution and argue that the main motive for his re-conceptualization is to be found in his rejection of Kraepelinian nosology. © The Author(s) 2014.

  18. Diagnosability issues in multiprocessor systems

    1989-01-01

    In a seminal paper on fault diagnosis, Preparata, Metze, and Chien introduced a graph-theoretical model. Barsi, Grandoni, and Maestrini relaxed some constraints in this model to create a different model for fault diagnosis. Both these models have become the subject of intense research in the past two decades. A major open problem for these models is the question of sequential t-diagnosability-Given an arbitrary system of units and that there are no more than t faulty units in it, can we always identify at least one faulty unit The author shows that this problem is co-NP complete in both models. Recent research has shown that there are polynomial time algorithms to find the maximum number of faulty units a system can withstand and still identify all of them from a single collection of test results. He presents improved algorithms to solve this problem in both models. Using the letters n,m, and {tau} to denote the number of units, the number of tests, and the maximum number of faulty units respectively, our results can be summarized as follows: in the model of Barsi, Grandoni, and Maestrini, the algorithm has a time complexity of O(n{tau}{sup 2}/log{tau}) improving on the currently known O(n{tau}{sup 2}); in the model of Preparata, Metze, and Chien, the algorithm has a complexity of O(n{tau}{sup 2.5}) improving on the currently known O(mn{sup 1.5}). He also presents related results in the latter model, which suggest the possibility of reducing the complexity even further. Finally, he develops a general scheme for characterizing diagnosable systems. Using this scheme, he solves the open problem of characterizing t/s and sequentially t-diagnosable systems. The characterizations are then used to rederive some known results.

  20. Distal DVT: worth diagnosing? Yes.

    Science.gov (United States)

    Schellong, S M

    2007-07-01

    Much of the argument for or against diagnosis of distal deep vain thrombosis (DVT) depends on the extra effort that has to be spent on it. This review presents the data on ultrasound of paired calf veins and calf muscle veins (distal ultrasound) in terms of protocols, feasibility, reliability and expected findings. In summary, provided there is adequate and anatomically sound training of sonographers, distal ultrasound is a valid, 4-minute procedure, which can easily be added to the examination of proximal veins. The second part of the review refers to the pathophysiology of ascending DVT, which is the most common type. Adequate patient care in terms of benefit, harm and cost includes a single non-invasive examination followed by risk adopted treatment allocation. This concept ideally should be valid for any type of DVT. The data extending this concept to distal DVT can only be derived from studies that look closely at this entity (i.e. in fact diagnose distal DVT). Even before these data are available, diagnosing distal DVT at least doubles the number of symptomatic patients in which signs and symptoms can be ascribed to a definitive diagnosis, which in itself is a benefit for patient care.

    The DSM-5 has been under revision since 1999 and is scheduled for publication in 2013. This article will review the major proposed modifications of the Paraphilias. The information reviewed was obtained from PubMed, PsychInfo, the DSM-5.org website and other sources and reviewed. Pedohebephilia, Hypersexual Disorder and Paraphilic Coercive Disorder are new proposed diagnoses. Paraphilias have been assigned their own chapter in DSM- 5 and a distinction has been made between Paraphilias and Paraphilic Disorders. Victim numbers have been included in diagnosis of paraphilias that involve victims and remission and severity measures have been added to all paraphilias. Transvestic Disorder can apply to males or females, Fetishistic Disorder now includes partialism, and Sexual Masochism Disorder has Asphyxiophilia as a specifier. This study is based on a literature review and influenced by the knowledge and biases of the authors. The Paraphilic Disorders Section of the DSM-5 represents a significant departure from DSMIV-TR.

    To determine the clinical manifestations and optimal management of female patients with advanced colorectal cancer (CRC) metastasis in ovaries mimicking advanced ovarian malignancy. A retrospective medical records review of female patients with primary CRC metastasis to ovaries, which were initially diagnosed as ovarian malignancy, and treated between 2001 and 2013. Clinical presentations, pathologic findings, and treatment outcomes were analyzed. In total, 19 cases were collected in the study through a hospital tumor registry. The mean age of the patients at the time of diagnosis was 45 years (range, 28-63 years). The most common symptoms were abdominal pain or increased abdominal girth (63%). None of them had rectal bleeding. The ratio of cancer antigen-125 to carcinoembryonic antigen was available in 13 out 19 patients (less than 25 in 76.9%). Barium enema or colonoscopic exam was only performed in 10 outpatients. None of them had a positive finding. All 19 patients went for surgery, all of them had ovarian metastasis but only eight of them had bilateral involvement, and 14 of them had carcinomatosis. All patients went for either optimal cytoreduction surgery or suboptimal cytoreduction surgery. The patients who received optimal cytoreduction surgery had a significant better progression-free and overall survival than those who did not. Clinical manifestations of primary CRC with ovarian metastasis may be confused with advanced ovarian cancer. Negative barium enema or colonoscopic exam cannot rule out the possibility of CRC. For patients with a cancer antigen-125 to carcinoembryonic antigen ratio less than 25, 76% are good reference of CRC metastasis to ovaries. Optimal cytoreduction surgery like that used for treating advanced ovarian cancer had a better prognosis than suboptimal cytoreduction colorectal cancer treatment. Copyright © 2017.

    It is important to identify the severity of acute pancreatitis (AP) in the early course of the disease. Clinical scoring systems may be helpful to predict the prognosis of patients with early AP; however, few analysts have forecast the accuracy of scoring systems for the prognosis in hyperlipidemic acute pancreatitis (HLAP). The purpose of this study was to summarize the clinical characteristics of HLAP and compare the accuracy of conventional scoring systems in predicting the prognosis of HLAP. This study retrospectively analyzed all consecutively diagnosed AP patients between September 2008 and March 2014. We compared the clinical characteristics between HLAP and nonhyperlipidemic acute pancreatitis. The bedside index for severity of acute pancreatitis (BISAP), Ranson, computed tomography severity index (CTSI), and systemic inflammatory response syndrome (SIRS) scores were applied within 48 hours following admission. Of 909 AP patients, 129 (14.2%) had HLAP, 20 were classified as severe acute pancreatitis (SAP), 8 had pseudocysts, 9 had pancreatic necrosis, 30 had pleural effusions, 33 had SIRS, 14 had persistent organ failure, and there was 1 death. Among the HLAP patients, the area under curves for BISAP, Ranson, SIRS, and CTSI in predicting SAP were 0.905, 0.938, 0.812, and 0.834, 0.874, 0.726, 0.668, and 0.848 for local complications, and 0.904, 0.917, 0.758, and 0.849 for organ failure, respectively. HLAP patients were characterized by younger age at onset, higher recurrence rate, and being more prone to pancreatic necrosis, organ failure, and SAP. BISAP, Ranson, SIRS, and CTSI all have accuracy in predicting the prognosis of HLAP patients, but each has different strengths and weaknesses.

    Full Text Available OBJECTIVES: The objective of this study was to investigate the long-term outcomes and prognostic factors for nasopharyngeal carcinoma (NPC in Han and Uyghur patients treated with intensity-modulated radiotherapy (IMRT in the Xinjiang region of China. MATERIALS AND METHODS: One hundred twenty-one Han and 60 Uyghur patients with newly diagnosed NPC without distant metastasis received IMRT at the Affiliated Tumor Hospital of Xinjiang Medical University between 2005 and 2008. The Kaplan-Meier method was used to estimate survival rates, and the log-rank test was used to evaluate differences in survival. RESULTS: Comparing Han and Uyghur patients, the 5-year overall survival (OS, disease-free survival (DFS, local control (LC, regional control (RC, and distant metastasis-free survival (DMFS rates were 81.9% vs 77.6% (P = 0.297, 72.1% vs 65.6% (P = 0.493, 88.3% vs 86.5% (P = 0.759, 95.0% vs 94.6% (P = 0.929, and 79.1% vs 75.2% (P = 0.613, respectively. Multivariate Cox proportional hazards regression identified the following independent prognostic factors in Han patients: N stage (P = 0.007 and age (P = 0.028 for OS, and age (P = 0.028 for DFS. OS differed significantly between Han and Uyghur patients >60 years old group (P = 0.036. Among Uyghur patients, the independent prognostic factors were age for OS (P = 0.033, as well as N stage (P = 0.037 and age (P = 0.021 for DFS. Additionally, Uyghur patients were less likely to experience mucositis and dermatitis than Han patients. CONCLUSION: Han and Uyghur patients with NPC had statistically significant differences in age, smoking history, and N staging. There was no significant difference in overall treatment outcomes with IMRT between these 2 ethnic populations in Xinjiang, China.

    We present the case of a 51 years old female-patient, with severe dextroscoliosis, having like unique symptom progressive dyspnea. The blood samples reveals polycythemia, the radiological exam shows the opacification of 2/3 of the left thorax, the absence of the lung structure in the other 1/3, the deviation of the mediastinum, and dextroscoliosis; the computed tomography reveals the absence of the left lung artery and the left airways, compensatory hyperinflation of the right lung and dilatation of the trunk and right pulmonary artery; the bronchoscopy does not visualize the carina or the left main bronchus, typical for pulmonary agenesis. Echocardiography confirmed the absence of left pulmonary artery and shows mild pulmonary hypertension (systolic pressure in the pulmonary artery of 33 mmHg) with dilatation of the right cavities, but good cinetics. We face a case of pulmonary agenesis lately diagnosed, with modest functional cardiologic implications, limited therapeutic options and good survival, justified by the late appearance of the pulmonary hypertension of low severity and without worsening in time.

    Buruli ulcer (BU) is a refractory skin ulcer caused by Mycobacterium ulcerans or M. ulcerans ssp. shinshuense, a subspecies thought to have originated in Japan or elsewhere in Asia. Although BU occurs most frequently in tropical and subtropical areas such as Africa and Australia, the occurrence in Japan has gradually increased in recent years. The World Health Organization recommends multidrug therapy consisting of a combination of oral rifampicin (RFP) and i.m. streptomycin (SM) for the treatment of BU. However, surgical interventions are often required when chemotherapy alone is ineffective. As a first step in developing a standardized regimen for BU treatment in Japan, we analyzed detailed records of treatments and prognoses in 40 of the 44 BU cases that have been diagnosed in Japan. We found that a combination of RFP (450 mg/day), levofloxacin (LVFX; 500 mg/day) and clarithromycin (CAM; at a dose of 800 mg/day instead of 400 mg/day) was superior to other chemotherapies performed in Japan. This simple treatment with oral medication increases the probability of patient adherence, and may often eliminate the need for surgery.

    The WHO declared tuberculosis (TB) a global emergency. An estimated 8-9 million new cases occur each year with 2-3 million deaths. Currently, TB is diagnosed mostly by chest-X ray and staining of the mycobacteria in sputum with a detection limit of 1x104 bacteria /ml. There is an urgent need for better diagnostic tools for TB especially for developing countries. We have validated the electronic nose from TD Technology for the detection of Mycobacterium tuberculosis by headspace analysis of 284 sputum samples from TB patients. We used linear discriminant function analysis resulting in a sensitivity of 75% a specificity of 67% and an accuracy of 69%. Further research is still required to improve the results by choosing more selective sensors and sampling techniques. We used a fast gas chromatography- mass spectrometry method (GC-MS). The automated procedure is based on the injection of sputum samples which are methylated inside the GC injector using thermally assisted hydrolysis and methylation (THM-GC-MS). Hexacosanoic acid in combination with tuberculostearic acid was found to be specific for the presence of M. tuberculosis. The detection limit was similar to microscopy. We found no false positives, all microscopy and culture positive samples were also found positive with the THM-GC-MS method. The detection of ribosomal RNA from the infecting organism offers great potential since rRNA molecules outnumber chromosomal DNA by a factor 1000. It thus may possible to detect the organism without amplification of the nucleic acids (NA). We used a capture and a tagged detector probe for the direct detection of M. tuberculosis in sputum. So far the detection limit is 1x106 bacteria / ml. Currently we are testing a Lab-On-A-Chip Interferometer detection system.

    Thomas, Katharine; Urrego, Fernando

    2017-01-01

    Background: Pediatric obesity is the most prevalent nutritional disorder in American children. The detrimental social, psychological, and physiological effects of obesity call for pediatricians to address this health concern. The literature demonstrates that clinicians are underreporting the diagnosis of obesity in the pediatric setting. The primary purpose of this study was to determine if pediatricians at one pediatrics clinic in the Ochsner Health System are documenting the presence of an overweight or obese body mass index (BMI) as a diagnosis in the medical record. A secondary purpose of this study was to determine the demographics of all pediatric patients in the Ochsner Health System to be used for program development. Methods: A retrospective medical record review was conducted. Records from April 1, 2012 to April 1, 2016, were reviewed for the presence of the diagnosis of BMI classified as obese or overweight. Results: We analyzed a total of 175,066 records in this study. Of these records, 1.32% documented a diagnosis of obesity, and 0.5% documented a BMI score indicating overweight. The percentages of patient visits that met the Centers for Disease Control and Prevention criteria to be classified as obese or overweight were 28.66% and 30.41%, respectively. The majority of our pediatric patients were male (51.76%), white (43.31%), and 5-12 years old (43.80%). Conclusion: This study demonstrates that pediatricians at Ochsner Health Center for Children are not diagnosing patients who have unhealthy BMI scores as overweight or obese. Interventions are needed to increase the identification of children who may benefit from receiving resources that encourage a healthy lifestyle and optimal weight maintenance. PMID:28331453

    The current study provides an overview of the research knowledge about unique problems encountered by transition-aged youths with dual diagnoses. A description of the considerable physical and emotional changes experienced by transition-aged youths provides a foundation for exploring the pressures and challenges compounded by mental health issues and substance abuse. Programs that provide intensive support throughout the transition years pay valuable dividends. However, transition-aged youths with dual diagnoses of mental disorders and substance abuse find themselves faced with limited or nonexistent options. There is a confusing lack of continuity and consistency of supports and services, which complicates the already perplexing circumstances that beleaguer the lives of young adults with dual diagnoses.

    Full Text Available Endobronchial ultrasound (EBUS imaging is commonly used to evaluate and aid in biopsy of mediastinal lymph nodes. Pulmonary arteries are readily viewable with this type of imaging modality. We present a case report of a pulmonary embolism (PE diagnosed by EBUS. Our patient had no smoking history and presented with respiratory and constitutional symptoms, urinary retention, and leg weakness suspicious for malignancy with metastasis to spine. Chest computed tomography (CT was suggestive of lung carcinoma and specifically showed no PE. EBUS with TBNA was requested for tissue diagnosis. A mobile filling defect consistent with a PE was observed and reported to primary team. Follow-up chest CT showed an acute PE which confirmed the diagnosis originally made by EBUS. Bronchoscopists should be aware of potential to diagnose a PE while performing EBUS. Additionally, there may be a role in using EBUS specifically to diagnose a PE in the right patient population.

    2012-12-01

    Full Text Available This article presents a case of anterior diffuse scleritis that initially was diagnosed as conjunctivitis. Anterior diffuse scleritis (ADS is a potentially vision-threatening inflammation of the sclera whose etiology may include autoimmune and systemic conditions such as rheumatoid arthritis and tuberculosis. The signs and symptoms of ADS include pain, tearing, tenderness, redness, painful sensitivity to light and decreased visual acuity. Ocular and physical examinations including blood tests to rule out underlying causes are important. Medications such as corticosteroids, non-steroidal anti-inflam-matory drugs and possibly immune-suppressants are used in the management of ADS. If care is not taken, ADS can be mis-diagnosed as conjunctivitis because the redness is similar in both conditions. Such mis-diagnosis can be sight-threatening and therefore it is essential that primary eye care practitioners are cautious in all diagnoses of red eye conditions. (S Afr Optom 2012 71(1 51-54

    Objective To evaluate the influence of thyroid disorders on the incidence and prognosis of acute myocardial infarction (AMI) patients. Methods A total of 463 AMI patients were included in the present study. The thyroid hormone levels were determined in all patients on the next day of admission. The patients were divided into different groups and the cardiac events were observed during hospitalization. Results Among the 463 patients, 239(51.6 % ) had normal thyroid hormone level, and 168 (36.3 % ) had non-thyroidal illness syndrome.There were 40 (8.6 % ) patients with subclinical hyperthyroidism and 6 ( 1.3 % ) with subclinical hypothyroidism.Hyperthyroidism and hypothyroidism were both found in 5 patients. Compared with the euthyroid group, the incidences of congestive heart failure, origin of shock incidence, and in-hospital death increased in the nonthyroidal illness syndrome group (P< 0. 05, 0. 01 ). Multivariate cox regression displayed that FT3 was an independent factor associated with long-term mortality. A decrease of 1 pmol/L in FT3 was associated with an increased risk of death by 59. 8%. Conclusion Thyroid disorder is frequently seen in patients with acute myocardial infarction. NTIS is significantly correlated with the short-time and long-time prognoses of AMI patients.%目的 探讨急性心肌梗死(AMI)时甲状腺功能紊乱的发生情况及对预后的影响.方法 人选463例AMI患者,入院次日测定甲状腺激素水平.观察住院期间心血管事件发生情况并进行远期随访.结果 AMI患者中甲状腺功能正常(功能正常组)239例(51.6%),非甲状腺性病态综合征(NTIS,NTIS组)168例(36.3%),亚临床甲状腺功能亢进症40例(8.6%),亚临床甲状腺功能减退6例(1.3%),甲状腺功能亢进5例(1.1%),甲状腺功能减退5例(1.1%).NTIS组在住院期间的充血性心力衰竭、心源性休克和死亡的发生率均显著高于功能正常组(P值分别<0.05、0.01).Cox模型分析显示,在校

    Idiopathic basal ganglia calcification (IBGC) is a rare, intractable disease with unknown etiology. IBGC3 is a familial genetic disease defined by genetic mutations in the major causative gene (SLC20A2). People with IBGC3 experience distress from the uncommon nature of their illness and uncertainty about treatment and prognoses. The present study aimed to describe the lives and illness of people with IBGC3. Participants were recruited from patients aged 20 years or older enrolled in a genetic study, who were diagnosed with IBGC3 and wanted to share their experiences. In-depth semi-structured interviews were conducted with six participants. Interviews were conducted between December 2012 and February 2014, and were recorded and transcribed verbatim. Qualitative data analysis was performed to identify categories and subcategories. Efforts were made to ensure the credibility, transferability, dependability, conformability, and validity of the data. Six thematic categories, 17 subcategories, and 143 codes emerged. The six categories were: (1) Frustration and anxiety with progression of symptoms without a diagnosis; (2) Confusion about diagnosis with an unfamiliar disease; (3) Emotional distress caused by a genetic disease; (4) Passive attitude toward life, being extra careful; (5) Taking charge of life, becoming active and engaged; and (6) Requests for healthcare. The qualitative data analysis indicated a need for genetic counseling, access to disease information, establishment of peer and family support systems, mental health services, and improvement in early intervention and treatment for the disease.

    New guidelines for managing acute otitis media include stricter criteria for properly diagnosing the condition and ensuring an accurate diagnosis before clinicians make treatment decisions. This is key because of the increase in antibiotic-resistant pathogens. This article focuses on how clinicians can use ancillary techniques and technologies to improve diagnostic accuracy for acute otitis media. Techniques include proper cerumen removal, visualizing the tympanic membrane with the correct otoscope, pneumatic otoscopy, using a spectral gradient acoustic reflectometer, and tympanometry.

    To design a fuzzy expert system to help detect and diagnose the severity of diabetic neuropathy. The research was completed in 2014 and consisted of two main phases. In the first phase, the diagnostic parameters were determined based on the literature review and by investigating specialists' perspectives (n = 8). In the second phase, 244 medical records related to the patients who were visited in an endocrinology and metabolism research centre during the first six months of 2014 and were primarily diagnosed with diabetic neuropathy, were used to test the sensitivity, specificity, and accuracy of the fuzzy expert system. The final diagnostic parameters included the duration of diabetes, the score of a symptom examination based on the Michigan questionnaire, the score of a sign examination based on the Michigan questionnaire, the glycolysis haemoglobin level, fasting blood sugar, blood creatinine, and albuminuria. The output variable was the severity of diabetic neuropathy which was shown as a number between zero and 10, had been divided into four categories: absence of the disease, (the degree of severity) mild, moderate, and severe. The interface of the system was designed by ASP.Net (Active Server Pages Network Enabled Technology) and the system function was tested in terms of sensitivity (true positive rate) (89%), specificity (true negative rate) (98%), and accuracy (a proportion of true results, both positive and negative) (93%). The system designed in this study can help specialists and general practitioners to diagnose the disease more quickly to improve the quality of care for patients.

    2012-01-01

    We examined the implications of test differences for defining and diagnosing comprehension deficits using reading comprehension tests. We had 995 children complete the Gray Oral Reading Test-3, the Qualitative Reading Inventory-3, the Woodcock-Johnson Passage Comprehension-3, and the Peabody Individual Achievement Test, and compared which children were identified by each test as being in the lowest 10%. Although a child who performs so poorly might be expected to do poorly on all tests, we found that the average overlap between tests in diagnosing comprehension difficulties was only 43%. Consistency in diagnosis was greater for younger children, when comprehension deficits are due to weaker decoding skills, than for older children. Inconsistencies between tests were just as evident when identifying the top performers. The different children identified as having a comprehension deficit by each test were compared on four profile variables - word decoding skill, IQ, ADHD symptoms, and working memory skill – to understand the nature of the different deficits assessed by each test. Theoretical and practical implications of these test differences in defining and diagnosing comprehension deficits are discussed. PMID:22442251

She was immediately diagnosed with pulmonary artery sarcoma based on a careful differential diagnosis and underwent surgery. Her tumor was pathologically diagnosed as leiomyosarcoma (i.e. intimal sarcoma. Pulmonary artery sarcoma can be easily confounded with thromboembolism in a clinical setting and some cases are diagnosed post mortem only. In our case, clinical prediction scores (Wells score, Geneva score, and revised Geneva score for the pulmonary embolism showed low probability. Moreover, chest CT showed uncommon findings for pulmonary thromboembolism, as the nodules were too big for thrombi. Because surgical resection can provide the only hope of long-term survival in cases of pulmonary artery sarcoma, clinicians should consider this possibility in the differential diagnosis of pulmonary embolism. Clinical prediction scores and CT findings might help to reach the correct diagnosis of pulmonary artery sarcoma.

    AIM To design a fuzzy expert system to help detect and diagnose the severity of diabetic neuropathy. METHODS The research was completed in 2014 and consisted of two main phases. In the first phase, the diagnostic parameters were determined based on the literature review and by investigating specialists’ perspectives (n = 8). In the second phase, 244 medical records related to the patients who were visited in an endocrinology and metabolism research centre during the first six months of 2014 and were primarily diagnosed with diabetic neuropathy, were used to test the sensitivity, specificity, and accuracy of the fuzzy expert system. RESULTS The final diagnostic parameters included the duration of diabetes, the score of a symptom examination based on the Michigan questionnaire, the score of a sign examination based on the Michigan questionnaire, the glycolysis haemoglobin level, fasting blood sugar, blood creatinine, and albuminuria. The output variable was the severity of diabetic neuropathy which was shown as a number between zero and 10, had been divided into four categories: absence of the disease, (the degree of severity) mild, moderate, and severe. The interface of the system was designed by ASP.Net (Active Server Pages Network Enabled Technology) and the system function was tested in terms of sensitivity (true positive rate) (89%), specificity (true negative rate) (98%), and accuracy (a proportion of true results, both positive and negative) (93%). CONCLUSION The system designed in this study can help specialists and general practitioners to diagnose the disease more quickly to improve the quality of care for patients. PMID:28265346

    Full Text Available PURPOSE: To test whether corneal hysteresis (CH and corneal resistance factor (CRF can discriminate between keratoconus and normal eyes and to evaluate whether the averages of two consecutive measurements perform differently from the one with the best waveform score (WS for diagnosing keratoconus. METHODS: ORA measurements for one eye per individual were selected randomly from 53 normal patients and from 27 patients with keratoconus. Two groups were considered the average (CH-Avg, CRF-Avg and best waveform score (CH-WS, CRF-WS groups. The Mann-Whitney U-test was used to evaluate whether the variables had similar distributions in the Normal and Keratoconus groups. Receiver operating characteristics (ROC curves were calculated for each parameter to assess the efficacy for diagnosing keratoconus and the same obtained for each variable were compared pairwise using the Hanley-McNeil test. RESULTS: The CH-Avg, CRF-Avg, CH-WS and CRF-WS differed significantly between the normal and keratoconus groups (p<0.001. The areas under the ROC curve (AUROC for CH-Avg, CRF-Avg, CH-WS, and CRF-WS were 0.824, 0.873, 0.891, and 0.931, respectively. CH-WS and CRF-WS had significantly better AUROCs than CH-Avg and CRF-Avg, respectively (p=0.001 and 0.002. CONCLUSION: The analysis of the biomechanical properties of the cornea through the ORA method has proved to be an important aid in the diagnosis of keratoconus, regardless of the method used. The best waveform score (WS measurements were superior to the average of consecutive ORA measurements for diagnosing keratoconus.

    Pediatric-onset bipolar disorder is common but often difficult to diagnose in younger patients. Clinicians should be sure to establish the presence of a full manic episode to make the diagnosis of bipolar I disorder. Because adult criteria are used for children and adolescents, clinicians also should be aware of developmental norms that can help to make an accurate diagnosis. Bipolar disorder NOS and other disorders in children and adolescents may be prodromal states for bipolar disorder, especially in the presence of a positive family history.

    Trauma is the most common cause of death in childhood, and abusive head trauma is the most common cause of traumatic death and morbidity in infants younger than 1 year. The main differential diagnosis of abusive head trauma is accidental traumatic brain injury, which is usually witnessed. This paper also discusses more uncommon diagnoses such as congenital and acquired disorders of hemostasis, cerebral arteriovenous malformations and metabolic diseases, all of which are extremely rare. Diagnostic imaging including CT and MRI is very important for the distinction of non-accidental from accidental traumatic injury. (orig.)

    Full Text Available We present three cases of trisomy 9 mosaicism diagnosed by amniocentesis with ongoing pregnancies after referral to our center due to fetal abnormalities. Two cases were associated with severe fetal growth restriction (FGR, each of which resulted in an intrauterine fetal demise (IUFD in the third trimester. The other case involved mild FGR with a congenital diaphragmatic hernia and resulted in a live birth with severe development delay. A major prenatal finding of trisomy 9 mosaicism is FGR. Fetuses with trisomy 9 mosaicism can rarely survive in the case of severe FGR.

  16. Diagnosing faults in autonomous robot plan execution

    Lam, Raymond K.; Doshi, Rajkumar S.; Atkinson, David J.; Lawson, Denise M.

    1988-01-01

    A major requirement for an autonomous robot is the capability to diagnose faults during plan execution in an uncertain environment. Many diagnostic researches concentrate only on hardware failures within an autonomous robot. Taking a different approach, the implementation of a Telerobot Diagnostic System that addresses, in addition to the hardware failures, failures caused by unexpected event changes in the environment or failures due to plan errors, is described. One feature of the system is the utilization of task-plan knowledge and context information to deduce fault symptoms. This forward deduction provides valuable information on past activities and the current expectations of a robotic event, both of which can guide the plan-execution inference process. The inference process adopts a model-based technique to recreate the plan-execution process and to confirm fault-source hypotheses. This technique allows the system to diagnose multiple faults due to either unexpected plan failures or hardware errors. This research initiates a major effort to investigate relationships between hardware faults and plan errors, relationships which were not addressed in the past. The results of this research will provide a clear understanding of how to generate a better task planner for an autonomous robot and how to recover the robot from faults in a critical environment.

    We employ Raman spectroscopy to diagnose benign and malignant lesions in human breast tissue based on chemical composition. In this study, 130 Raman spectra are acquired from ex vivo samples of human breast tissue (normal, fibrocystic change, fibroadenoma, and infiltrating carcinoma) from 58 patients. Data are fit by using a linear combination model in which nine basis spectra represent the morphologic and chemical features of breast tissue. The resulting fit coefficients provide insight into the chemical/morphological makeup of the tissue and are used to develop diagnostic algorithms. The fit coefficients for fat and collagen are the key parameters in the resulting diagnostic algorithm, which classifies samples according to their specific pathological diagnoses, attaining 94% sensitivity and 96% specificity for distinguishing cancerous tissues from normal and benign tissues. The excellent results demonstrate that Raman spectroscopy has the potential to be applied in vivo to accurately classify breast lesions, thereby reducing the number of excisional breast biopsies that are performed.

    Meconium peritonitis is a rare prenatal disease with an increased rate of morbidity and mortality in the neonatal period. Distinctive features revealed by prenatal and postnatal ultrasoundmay be present: abdominal calcifications, ascites, polyhydramnios, meconium pseudocyst, echogenic mass and dilated bowel or intestinal obstruction. Establishing clear postnatal treatment and prognosis is difficult because of the heterogeneity of the results obtained by ultrasound. The aim of the study is to determine how prenatal diagnosis of meconium peritonitis is associated with perinatal management and further evolution. Clinical results are different depending on the presence of antenatal diagnosis of meconium peritonitis and its form, which can be mild or severe. Surgical treatment and management of meconium peritonitis depend on the clinical presentation of the newborn. Meconium peritonitis diagnosed prenatally differs from that of the newborn, not only concerning the mortality rates but also through reduced morbidity and overall better prognosis. Celsius.

    We have, in this preliminary study, investigated the use of optical coherence tomography for diagnosis of periodontal disease. We took in vitro OCT images of the dental and periodontal tissues from a young pig and compared them to histological sections. These images distinguish tooth and soft tissue relationships that are important in diagnosing and assessing periodontal disease. We have imaged the attachment of gingiva to the tooth surface and located the cemento-enamel junction. This junction is an important reference point for defining attachment level in the diagnosis of periodontal disease. the boundary between enamel and dentin is also visible for most of the length of the anatomical crown, allowing quantitation of enamel thickness and character.

  1. Diagnosing Myocardial Contusion after Blunt Chest Trauma

    2016-10-01

    Full Text Available A myocardial contusion refers to a bruise of the cardiac muscle, the severity of which can vary depending on the severity of the injury and when the injury occurs. It is a major cause of rapid death which happens after blunt chest trauma and should be suspected at triage in the emergency department. We demonstrated that suspected myocardial contusion patients who have normal electrocardiograms (ECGs and biomarker tests can be safely discharged. However, if the test results are abnormal, the next steps should be echocardiography and more advanced measures. Diagnosing myocardial contusion is very difficult because of its nonspecific symptoms. If a myocardial contusion happens, cardiogenic shock or arrhythmia must be anticipated, and the patient must be carefully monitored.

    In this case report, clinical and electrophysiological findings of 43-year-old female patient who developed Clostridium botulinum intoxication after consumption of home-made canned food are presented. Following the sudden onset of severe nausea and vomiting, diplopia, blurred vision, bilateral ptosis, weakness, speech and swallowing difficulties have developed and the patient declared that she has just tasted the canned beans after she had rinsed them several times. The case, where serological tests cannot be performed, was diagnosed clinically and treated with antitoxin immediately. During follow-up, consecutive nerve stimulation was performed and significant incremental response was observed. There was an improvement in symptoms within 2 weeks, and in 5 or 6 weeks the symptoms had disappeared completely. Electrodiagnostic studies revealed that the findings turned to normal. The case showed that immediate antitoxin treatment is life-saving even the diagnosis of botulinum intoxication is based on clinical findings.

    Mucocele of the appendix is an infrequent entity, characterized by distension of the lumen due to accumulation of mucoid substance and is rarely diagnosed preoperatively. If untreated, mucocele may rupture producing a potentially fatal entity known as pseudomyxoma peritonei. The type of surgical treatment is related to the dimensions and the histology of the mucocele. Appendectomy is used for simple mucocele or for cystadenoma. Right hemi-colectomy is recommended for cystadeno carcinoma. In this paper, we report a case of an asymptomatic 37-year-old woman in whom mucocele was found on a routine ultrasound examination and preoperative computed tomography scan. Surgery revealed a big appendix measuring 84 mm in length and 40 mm in diameter. The final pathologic diagnosis was simple mucocele. Celsius.

    We report the prenatal diagnosis of trisomy 6 mosaicism via amniocentesis, in which trisomy 6 cells were identified in three of five culture vessels with 33% (5/15) of colonies showing trisomic cells. The pregnancy was electively terminated and examination revealed minor abnormalities (shortening of the femurs, micrognathia, posterior malrotation of the ears, and bilateral camptomelia of the second digit of the hands and fifth digits of the feet). Cytogenetic analysis of the placenta showed trisomy 6 in 100% of 20 cells studied. Karyotype was 46,XX in 100 cells examined from fetal skin. There are relatively few prenatally diagnosed cases of mosaic trisomy 6 at amniocentesis. Confined placental mosaicism (CPM) has been postulated in other cases where follow-up cytogenetic studies were not available. The present case differs from those previously reported, as it appears to represent CPM of chromosome 6 with phenotypic effects to the fetus.

    2003-01-01

    Full Text Available Diphyllobothrium pacificum has been reported as a human parasite from coprolites and skeletons in Peru and Chile. Our analysis of Chinchorro mummies from Chile provides the oldest evidence of D. pacificum directly associated with human mummies. These mummies date between 4,000 and 5,000 years ago. The basis for our diagnosis is presented. We find that the size of the eggs in the mummies is smaller than other discoveries of D. pacificum. We suggest that this is due to the peculiar circumstances of preservation of parasite eggs within mummies and the release of immature eggs into the intestinal tract as the tapeworms decompose after the death of the host. This information is important to consider when making diagnoses from mummies.

    Discrete Event Systems: Diagnosis and Diagnosability addresses the problem of fault diagnosis of Discrete Event Systems (DES). This book provides the basic techniques and approaches necessary for the design of an efficient fault diagnosis system for a wide range of modern engineering applications. The different techniques and approaches are classified according to several criteria such as: modeling tools (Automata, Petri nets) that is used to construct the model; the information (qualitative based on events occurrences and/or states outputs, quantitative based on signal processing and data analysis) that is needed to analyze and achieve the diagnosis; the decision structure (centralized, decentralized) that is required to achieve the diagnosis. The goal of this classification is to select the efficient method to achieve the fault diagnosis according to the application constraints. This book focuses on the centralized and decentralized event based diagnosis approaches using formal language and automata as mode...

    2006-01-01

    The gastroesophageal reflux (GER) disease is a very frequent digestive disorder, mainly characterised by the reflux of the gastric acidic content to the esophage in abnormal quantities. There are different situations that favour this situation but almost in all of them rely an incompetence of the esophagic sphincter. The clinical consequences are many, including oral manifestations. Among all of them the most frequent is the esophagitis followed by symptoms at the pharynx or larynx and finally, the oral cavity. At this level fundamentally we will find enamel and oral mucosa erosions. We report the case of a patient who was indirectly diagnosed of her esophague disease by the observation of the alterations in the occlusal splint induced by the gastric reflux. We review the literature concerning the above topic and its possible association with the miofascial syndrome.

    2012-03-15

    Background. In the Taiwanese military, flatfoot is indicated by a calcaneal-fifth metatarsal angle (arch angle) =165 deg . However, the arch angle is not always easily defined. Purpose. To assess correlations between the arch angle and other radiographic measures and thus identify an alternative radiographic measure for diagnosing flatfoot. Material and Methods Eighty-seven male Taiwanese military recruits were studied (median age 22 years, interquartile range 20-23 years). Lateral, weight-bearing radiographs were taken. Five radiographic measurements, including the calcaneal-fifth metatarsal angle (arch angle), medial arch angle (MAA), calcaneal pitch angle (CP), talus angle (TA), and talar-first metatarsal angle (TFM) were made. Correlations between the arch angle and all other measures were determined. A cut-off value for predicting flatfoot (arch angle >=165 deg ) was determined for each measure using the Youden index and receiver-operating characteristic (ROC) curves were generated for each measure to assess diagnostic accuracy. Results. All measures were significantly correlated with arch angle (P < 0.05); however, the strongest correlation was for CP (rho = -0.905, P < 0.001). CP was associated with the highest area under the ROC (0.988 vs. 0.711-0.912 for the other measures). Further, CP (cut-off <12.3 deg ) had the highest sensitivity (92.0%), positive predictive value (76.7%), and negative predictive value (96.5%). TFM (>9.5 deg ) had the highest specificity (90.3% vs. 88.75 for CP <12.3 deg ). Conclusion. CP is inversely correlated with arch angle in Taiwanese male military recruits. CP < 12.3 deg is a significant predictor of flatfoot. Assessment of CP may be used as an alternative means of diagnosing flatfoot when the arch angle is not easily defined

  15. Diagnosing chronic thromboembolic pulmonary hypertension: current perspectives

    2014-09-01

    Full Text Available Charaka Hadinnapola, Deepa Gopalan, David P Jenkins Papworth Hospital National Health Service Foundation Trust, Papworth Everard, Cambridge, United Kingdom Abstract: Chronic thromboembolic pulmonary hypertension is a rare and relatively poorly understood disease. It remains underdiagnosed and is often not recognized in primary and secondary care, as its symptoms are nonspecific and there are few clinical signs until late in the disease process. However, pulmonary endarterectomy (PEA offers a potential cure for patients with this type of pulmonary hypertension; therefore, it is important that they are identified and diagnosed in a timely manner. PEA is associated with a 2.2%–5% risk of significant morbidity and mortality, even in experienced PEA centers. Therefore, once chronic thromboembolic pulmonary hypertension is diagnosed, further assessment of operability and patient selection is crucial. Assessment of operability involves determining the distribution and burden of chronic thromboembolic disease, assessing pulmonary hemodynamics, and assessing the functional impairment of the patient. Ventilation perfusion scintigraphy is of value in screening for the presence of chronic thromboembolic disease. However, computer tomography pulmonary angiography and magnetic resonance pulmonary angiography are now increasingly used to image the vascular occlusions directly. This allows assessment of the surgically accessible disease burden. Some centers still advocate conventional selective pulmonary angiography for the latter. Right-heart catheterization remains the gold standard for assessing pulmonary hemodynamics. Higher pulmonary vascular resistances are associated with poorer outcomes as well as increased risks at the time of surgery. This is in part because of the presence of more distal chronic thromboembolic material and distal pulmonary artery remodeling. However, in experienced centers, these patients are being operated on safely and with good

    Full Text Available Hydronephrosis is the most common abnormal finding in the urinary tract on prenatal screening with ultrasonography (U/S. Hydronephrosis may be obstructive or non-obstructive; obstructive lesions are more harmful to the developing kidneys. The aim of the study was to evaluate the causes of renal pelvic dilatation and the outcome of postnatal treatment in infants with hydronephrosis diagnosed prenatally with U/S. We prospectively studied 67 (60 males newborns with hydronephrosis diagnosed prenatally and confirmed postnatally with U/S from Sept. 2005 to Oct. 2007. The patients were allocated to three groups based on the mea-surement of the anteroposterior renal pelvic diameter (APRPD in transverse plane: mild (6-9.9 mm, moderate (10-14.9 mm and severe (> 15 mm hydronephrosis. Voiding cystourethrography (VCUG was obtained in all of the patients to rule out vesicoureteral reflux (VUR. In cases with negative VUR, Diethylenetriamine-pentaacetic acid (DTPA scan with diuretic renography was performed to detect ureteropelvic joint obstruction (UPJO. Twenty two cases (32.8% had mild, 20 (29.9% had moderate, and 25 (37.3% had severe hydronephrosis. The causes of hydroneph-rosis were VUR (40.2%, UPJO (32.8%, posterior urethral valves (PUVs (13.4 %, and transient hydronephrosis (13.4 %. The lesion was obstructive in 37 (55.2% infants. Totally, 33 (49.2% patients with hydronephrosis (9 mild, 9 moderate, and 15 severe subsequently developed com-plications such as UTI and renal insufficiency, or required surgery. Associated abnormalities were observed in 15 (22.4% patients. We conclude that every newborn with any degree of hydro-nephrosis should be assessed postnatally for specific diagnosis and treatment.

  17. Queer diagnoses revisited: The past and future of homosexuality and gender diagnoses in DSM and ICD.

    Drescher, Jack

    2015-01-01

    The American Psychiatric Association (APA) recently completed a several year process of revising the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). During that time, there were objections raised to retaining DSM's gender identity disorder diagnoses and calls to remove them, just as homosexuality had been removed from DSM-II in 1973. At the conclusion of the DSM-5 revision process, the gender diagnoses were retained, albeit in altered form and bearing the new name of 'gender dysphoria'. The author of this paper was a member of the DSM-5 Workgroup on Sexual and Gender Identity Disorders and presently serves on the WHO Working Group on Sexual Disorders and Sexual Health. Both groups faced similar tasks: reconciling patients' needs for access to care with the stigma of being given a psychiatric diagnosis. The differing nature of the two diagnostic manuals led to two different outcomes. As background, this paper updates the history of homosexuality and the gender diagnoses in the DSM and in the International Statistical Classification of Diseases and Related Health Problems (ICD) as well as what is expected to happen to the homosexuality and gender diagnoses following the current ICD-11 revision process.

    Prenatal US detection of cloacal malformations is challenging and rarely confirms this diagnosis. To define the prenatal MRI findings in cloacal malformations. We performed a retrospective study of patients with cloacal malformations who had pre- and post-natal assessment at our institution. Fetal MRI was obtained in six singleton pregnancies between 26 and 32 weeks of gestation. Imaging analysis was focused on the distal bowel, the urinary system and the genital tract and compared with postnatal clinical, radiological and surgical diagnoses. The distal bowel was dilated and did not extend below the bladder in five fetuses. They had a long common cloacal channel (3.5-6 cm) and a rectum located over the bladder base. Only one fetus with a posterior cloacal variant had a normal rectum. Three fetuses had increased T2 signal in the bowel and two increased T1/decreased T2 signal bladder content. All had renal anomalies, four had abnormal bladders and two had hydrocolpos. Assessment of the anorectal signal and pelvic anatomy during the third trimester helps to detect cloacal malformations in the fetus. The specificity for this diagnosis was highly increased when bowel fluid or bladder meconium content was identified. (orig.)

    Full Text Available Mitochondrial disorders (MIDs require biochemical or genetic investigations for being diagnosed. In some cases, however, the diagnosis can be suspected upon the syndromic phenotype or upon clinical presentation and family history, as in the following case. The patient was a 74-year-old male admitted for worsening of pre-existing left-sided ptosis and ophthalmoparesis after a birthday party. The history was positive for arterial hypertension, hypertrophic cardiomyopathy with systolic dysfunction, diabetes-type 2, mild renal insufficiency, thyroiditis, and polyneuropathy. Instrumental investigations additionally revealed hepatopathy, hyperlipidemia, hyperuricemia, bifascicular block, white matter lesions, and subacute stroke. Systolic dysfunction resolved upon adequate cardiac treatment. On hospital day 11 the patient suddenly developed asystole. He was successfully resuscitated but died a few hours later from acute myocardial infarction. Surprisingly, a more extensive family history was positive for myopathy (patient, brother, daughter, neuropathy (patient, hypoacusis (patient, Parkinson syndrome (mother, spasticity (son, diabetes (patient, son, renal failure (patient, and generalized atherosclerosis (patient. The individual and family history was strongly suggestive of an MID. In conclusion, individual and family history may strongly suggest MID. Phenotypic variability may be high between family members affected by an MID. MID may be associated with an increasing atherosclerotic risk lastly resulting in coronary heart disease and death.

    Full Text Available This paper introduces an expert System (ES named as “CADRE-Computer Assisted Diagnoses for Red Eye. Mostly the remote areas of the population are deprived of the facilities of having experts in eye disease. So it is the need of the day to store the expertise of Eye specialists in computers through using ES technology. This ES is a rule-based Expert System that assists in red-eye diagnosis and treatment. The knowledge acquired from literature review and human experts of the specific domain was used as a base for analysis, diagnosis and recommendations. CADRE evaluates the risk factors of 20 eye diseases and works just like an ophthalmologist, which will be useful for students, doctors and researchers as well as to patients. This expert system (ES was developed through using ESTA, VISUAL BASIC, MS-EXCEL, Seagate Crystal Reports and Image Styler. This ES is not limited to the Red-eye diseases but can be extended to all types of eye-diseases.

    Full Text Available Beijing Municipality, characterised by the ‘off-ground’ architecture distinguishing neo-liberal privatisation, is attempting to mitigate the damaging effects of rampant development on the social fabric, cultural heritage, and the environment by adopting sustainable urban planning. I argue that the sustainability rhetoric in the Beijing Municipality 2020 Plans functions in part as strategic metaphors masking unnamed, imminent threats to governance. In this article I diagnose four Beijing plans (Beijing 2006-2015 ‘Rail Transit Plan’ for Compact City, Beijing 2005-2020 ‘Underground Space Plan’ for Alternative Space, Beijing 2006-2020 ‘Undeveloped Area Plan’ for Ecological Responsibility, and Beijing 2006-2010 ‘Low-income Housing Plan’ for Affordability and Liveability. A diagrammatics of the plans illuminates not so much a mapping of Beijing’s future as the forms of spontaneity preoccupying the nation at this historical juncture. The Beijing 2020 plan, as city mapping more generally, discloses the imminence of ungovernable city. The fact that citizens are demanding greater authority over Beijing governance suggests that radical alterations to its urban fabric and quality of life have incited the imminent sociability that is the city.

  3. Diagnosing young onset dementia can be challenging.

    2016-05-01

    Although the risk of developing dementia increases with age, onset can be as early as the third or fourth decade of life. Genetic influences play a more important role in younger than in older people with dementia, so young onset dementia may cluster in families. Diagnosing young onset dementia is challenging. The range of possible presenting features is broad, encompassing behavioural, cognitive, psychiatric and neurological domains, and symptoms are often subtle initially. Frequently the complaints are misattributed to stress or depression, and the patient is falsely reassured that they are too young to have dementia. The most common causes of young onset dementia are early onset forms of adult neurodegenerative conditions and alcohol. Vascular dementia is the second most common cause of young onset dementia after Alzheimer's disease. Conventional vascular risk factors may be absent and diagnosis relies on imaging evidence of cerebrovascular disease. Obtaining a detailed history remains the most important part of the workup and usually requires corroboration by a third party. Undertaking a basic neurological examination is also important. Those with suspected young onset dementia should be referred to a neurology-led cognitive disorders clinic where available as the differenti diagnosis is considerably broader tha in older adults and requires specialist investigation.

  4. Peptidomic Identification of Serum Peptides Diagnosing Preeclampsia.

    Qiaojun Wen

    Full Text Available We sought to identify serological markers capable of diagnosing preeclampsia (PE. We performed serum peptide analysis (liquid chromatography mass spectrometry of 62 unique samples from 31 PE patients and 31 healthy pregnant controls, with two-thirds used as a training set and the other third as a testing set. Differential serum peptide profiling identified 52 significant serum peptides, and a 19-peptide panel collectively discriminating PE in training sets (n = 21 PE, n = 21 control; specificity = 85.7% and sensitivity = 100% and testing sets (n = 10 PE, n = 10 control; specificity = 80% and sensitivity = 100%. The panel peptides were derived from 6 different protein precursors: 13 from fibrinogen alpha (FGA, 1 from alpha-1-antitrypsin (A1AT, 1 from apolipoprotein L1 (APO-L1, 1 from inter-alpha-trypsin inhibitor heavy chain H4 (ITIH4, 2 from kininogen-1 (KNG1, and 1 from thymosin beta-4 (TMSB4. We concluded that serum peptides can accurately discriminate active PE. Measurement of a 19-peptide panel could be performed quickly and in a quantitative mass spectrometric platform available in clinical laboratories. This serum peptide panel quantification could provide clinical utility in predicting PE or differential diagnosis of PE from confounding chronic hypertension.

    Full Text Available The aim of the study is to evaluate the performance of the firms surveyed against the importance of the opportunities, threats, strengths and weaknesses applicable to those firms using Importance-Performance analysis. Firms optimize their Strengths, Weaknesses, Opportunities and Threats with the help of SWOT analysis. Martilla and James (1977 popularized the Importance-Performance analysis through their study titled with the same name. Importance-Performance analysis can be used to evaluate the performance against the intention or plan formulated by business or non-business firms. This method is widely used in consumer satisfaction studies and competitor analysis. Quite often right decisions can be taken if the information is presented in a comprehensive and understandable manner and in these contexts, Importance-Performance measure scores well. To the best of the author’s knowledge, Importance-Performance Analysis is used for the first time in the study to diagnose the strengths, weaknesses, opportunities and threats applicable to a firm.

  6. Intramuscular and intermuscular lipoma: neglected diagnoses.

    Fletcher, C D; Martin-Bates, E

    1988-03-01

    Fifty-four cases of lipoma arising either within or between skeletal muscles are presented. Of these, 52 were identified in a systematic review of 2478 tumours of adipose tissue diagnosed and treated in one hospital over a 25 year period. Intramuscular lipomas account for 1.8% of fatty tumours, arise predominantly in middle to late adult life and, in our series, are commonest on the trunk. They may be divided into infiltrative and well-circumscribed types, respective local recurrence rates being 19 and 0%. Intermuscular lipomas are comparatively rare, 0.3% of fatty tumours, have a similar age distribution and arise most often in the anterior abdominal wall; none of the seven cases recurred. It is important that both pathologists and surgeons appreciate the significant tendency of infiltrative intramuscular lipomas to recur. Hence, preventative surgical measures may be undertaken and worries that the lesion may be sarcomatous can be avoided. Differential diagnosis, most importantly from well-differentiated liposarcoma, is discussed.

    A significant proportion of the workforce in industrialized countries (16%) are employed as shift workers. These workers may be susceptible to shift work disorder (SWD), a circadian rhythm sleep disorder, particularly those who work at night or on early-morning shifts. Shift work disorder remains an underdiagnosed and undertreated problem among this population. Patients with SWD have difficulty initiating sleep and waking up. Often, these patients have excessive sleepiness during their work shift. Shift work disorder has been associated with decreased productivity, impaired safety, diminished quality of life, and adverse effects on health. Several tools have been validated to assess excessive daytime sleepiness and are often used to assess excessive nighttime sleepiness, such as that experienced in patients with SWD, including the Epworth Sleepiness Scale and the Multiple Sleep Latency Test. The criteria for diagnosing SWD as established by the American Academy of Sleep Medicine (AASM) and published in the International Classification of Sleep Disorders-Second Edition (ICSD-2) were most recently updated in 2005 and thus do not contain newer agents approved for use in patients with SWD. The symptoms of SWD can be treated using behavioral, prescription, and nonprescription therapies. Current treatment guidelines suggest nonpharmacologic interventions, such as exercise and exposure to light. In addition, medications that contain melatonin or caffeine may have clinical benefits in some patients with SWD. However, modafinil and armodafinil are approved by the US Food and Drug Administration to improve wakefulness in patients with excessive sleepiness associated with SWD, and recent data suggest a clinical benefit. The use of these therapies can significantly improve sleep, performance, and quality of life for patients with SWD.

  10. Can intramuscular glucose levels diagnose compartment syndrome?

    Doro, Christopher J; Sitzman, Thomas J; O'Toole, Robert V

    2014-02-01

    Compartment syndrome is difficult to diagnose, particularly in patients who are not able to undergo adequate clinical examination. Current methods rely on pressure measurements within the compartment, have high false-positive rates, and do not reliably indicate presence of muscle ischemia. We hypothesized that measurement of intramuscular glucose and oxygen can identify compartment syndrome with high sensitivity and specificity. Compartment syndrome was created in 12 anesthetized adult mixed-sex beagles, in the craniolateral compartment of a lower leg, by infusion of lactated Ringer's solution with normal serum concentration of glucose. The contralateral leg served as a control. Hydrostatic pressure, oxygen tension, and glucose concentration were recorded with commercially available probes. Compartment syndrome was maintained for 8 hours, and the animals were recovered. Two weeks later, compartment and control legs underwent muscle biopsy. Specimens were reviewed by a blinded pathologist. Within 15 minutes of creating compartment syndrome, glucose concentration and oxygen tension in the experimental limb were significantly lower than in the control limb (glucose, p = 0.02; oxygen, p = 0.007; two-tailed t test). Intramuscular glucose concentration of less than 97 mg/dL was 100% sensitive (95% confidence interval [CI], 73-100%) and 75% specific (95% CI, 40-94%) for the presence of compartment syndrome. Partial pressure of oxygen less than 30 mm Hg was 100% sensitive (95% CI, 72-100%) and 100% specific (95% CI, 69-100%) for the presence of compartment syndrome. Pathology confirmed compartment syndrome in all experimental limbs. Our results show that intramuscular glucose concentration and partial pressure of oxygen rapidly identify muscle ischemia with high sensitivity and specificity after experimentally created compartment syndrome in this animal model.

    2010-01-01

    Both intermittent and persistent faults may occur in a wide range of systems. We present in this paper the introduction of intermittent fault handling techniques into ProDiagnose, an algorithm that previously only handled persistent faults. We discuss novel algorithmic techniques as well as how our static Bayesian networks help diagnose, in an integrated manner, a range of intermittent and persistent faults. Through experiments with data from the ADAPT electrical power system test bed, generated as part of the Second International Diagnostic Competition (DXC-10), we show that this novel variant of ProDiagnose diagnoses intermittent faults accurately and quickly, while maintaining strong performance on persistent faults.

    To propose two NANDA diagnoses--ethical dilemma and moral distress--and to distinguish between the NANDA diagnosis decisional conflict and the proposed nursing diagnosis of ethical dilemma. Journal articles, books, and focus group research findings. Moral/ethical situations exist in health care. Nurses' experiences of ethical dilemmas and moral distress are extrapolated to the types and categories of ethical dilemmas and moral distress that patients experience and are used as the basis for development of two new nursing diagnoses. The two proposed NANDA diagnoses fill a void in current standardized terminology. It is important that nurses have the ability to diagnose ethical or moral situations in health care. Currently, NANDA does not offer a means to document this important phenomenon. The creation of two sets of nursing diagnoses, ethical dilemma and moral distress, will enable nurses to recognize and track nursing care related to ethical or moral situations.

    2007-02-12

    People with flu-like symptoms who seek treatment at a medical clinic or hospital often must wait several hours before being examined, possibly exposing many people to an infectious virus.

    People with flu-like symptoms who seek treatment at a medical clinic or hospital often must wait several hours before being examined, possibly exposing many people to an infectious virus. If a patient appears to need more than the routine fluids-and-rest prescription, effective diagnosis requires tests that must be sent to a laboratory. Hours or days may pass before results are available to the doctor, who in the meantime must make an educated guess about the patient's illness. The lengthy diagnostic process places a heavy burden on medical laboratories and can result in improper use of antibiotics or a costly hospital stay. A faster testing method may soon be available.

    2010-06-01

    Full Text Available Abstract Background Previous research has documented that the symptoms of bipolar disorder are often mistaken for unipolar depression prior to a patient's first bipolar diagnosis. The assumption has been that once a patient receives a bipolar diagnosis they will no longer be given a misdiagnosis of depression. The objectives of this study were 1 to assess the rate of subsequent unipolar depression diagnosis in individuals with a history of bipolar disorder and 2 to assess the increased cost associated with this potential misdiagnosis. Methods This study utilized a retrospective cohort design using administrative claims data from 2002 and 2003. Patient inclusion criteria for the study were 1 at least 2 bipolar diagnoses in 2002, 2 continuous enrollment during 2002 and 2003, 3 a pharmacy benefit, and 4 age 18 to 64. Patients with at least 2 unipolar depression diagnoses in 2003 were categorized as having an incongruent diagnosis of unipolar depression. We used propensity scoring to control for selection bias. Utilization was evaluated using negative binomial models. We evaluated cost differences between patient cohorts using generalized linear models. Results Of the 7981 patients who met all inclusion criteria for the analysis, 17.5% (1400 had an incongruent depression diagnosis (IDD. After controlling for background differences, individuals who received an IDD had higher rates of inpatient and outpatient psychiatric utilization and cost, on average, an additional $1641 per year compared to individuals without an IDD. Conclusions A strikingly high proportion of bipolar patients are given the differential diagnosis of unipolar depression after being identified as having bipolar disorder. Individuals with an IDD had increased acute psychiatric care services, suggesting higher levels of relapses, and were at risk for inappropriate treatment, as antidepressant therapy without a concomitant mood-stabilizing medication is contraindicated in bipolar

  6. CT-MPR invaluable in diagnosing odontogenic maxillary sinusitis

    In everyday examination, it is usual to encounter odontogenic maxillary sinusitis patients. Odontogenic maxillary sinusitis is generally best diagnosed by dental X-ray imaging. Many medical facilities not having a dental X-ray unit use coronal computed tomography (CT) images to diagnose odontogenic maxillary sinusitis. Coronal CT imaging causes artifacts, however due to dental prosthesises. Computed tomography-Multiplanar reformation (CT-MPR) imaging has proved useful in evaluating the paranasal sinus because it is not influenced by dental prosthesises. We evaluated the usefulness of CT-MPR for diagnosing odontogenic maxillary sinusitis by retrospectively analyzing 16 patients, with the following results. We couldn't diagnose all cases of odontogenic maxillary sinusitis in posteroanterior and Waters projection images. Panoramic radiography is needed to diagnose odontogenic maxillary sinusitis. Dental X-ray imaging missed some cases, but all cases were diagnosed by CT-MPR imaging, giving a 100% diagnosestic rate. CT-MPR imaging is thus at least as valuable or better than dental X-ray imaging in diagnosing odontogenic maxillary sinusitis. (author)

    Objective Shoulder complaints are frequently encountered in general practice, but precise diagnosing is challenging. This study investigated agreement of shoulder complaints diagnoses between clinicians in a primary health care setting. Design Cross-sectional study. Setting Four primary health care clinicians used patients’ history and functional examination of the shoulder by selective tissue tension techniques (STTs), to diagnose shoulder complaints. Subjects 62 patients, aged 18–75 years. Main outcome measure Reliability of diagnoses was assessed by observed intertester agreement and Cohen’s kappa. A total of 372 diagnostic pairs were available for intertester comparisons. Results Six diagnoses were assigned by all clinicians; supraspinatus-, infraspinatus-, subscapularis-tendinopathies; chronic subacromial bursitis; glenohumeral capsulitis, and acromioclavicular joint lesion. The observed agreement on these diagnoses ranged from 0.84 for glenohumeral capsulitis to 0.97 for acromioclavicular joint lesion. Kappa scores were 0.46 (95% CI 0.33, 0.58) for chronic subacromial bursitis; 0.53 (95% CI 0.34, 0.68), 0.59 (95% CI 0.47, 0.70), and 0.68 (95% CI 0.53, 0.82) for infraspinatus -, supraspinatus -, and subscapularis-tendinopathy, respectively. For glenohumeral capsulitis and acromioclavicular lesion kappa scores were 0.66 (95% CI 0.57, 0.73) and 0.78 (95% CI 0.61, 0.90). Kappa scores were higher for individual diagnoses than for individual tests, except for limitation in passive abduction (0.70, 95% CI 0.62, 0.78) and passive lateral rotation (0.66, 95% CI 0.57, 0.73). Conclusions Although experienced clinicians showed substantial intertester agreement, precise diagnoses of shoulder complaints in primary health care remain a challenge. The present results call for further research on refined diagnoses of shoulder complaints. Key Points Based on medical history and a systematic functional examination by selective tissue tension techniques (STTs), we

    Current diagnosing phase shifting interferometry is a time and funds consuming process. Hence a brief and effective method is necessary to satisfy the real-time testing. In this paper, mathematical solutions for errors were deduced from the difference of intensity patterns. Based on the diversity of error distributions, an effective method for distinguishing and diagnosing the error sources is proposed and verified by an elaborative designed simulation. In the actual comparison experiment, vibration, phase-shift error and intensity fluctuation were imposed to demonstrate this method. The results showed that this method can be applied into the real-time measurement and provide an in situ diagnosing technique.

    Magnetic resonance (MR) imaging of Morton neuromas is highly accurate. Morton neuromas are more conspicuous when the patient is prone positioned and the foot is plantar flexed than in the supine position with the toes pointing upward. MR imaging of Morton neuromas has a large influence on the diagnostic thinking and treatment plan of orthopedic foot surgeons. The most common differential diagnoses include intermetatarsal bursitis, stress fractures, and stress reactions. Some diagnoses (nodules associated with rheumatoid arthritis, synovial cyst, soft tissue chondroma, and plantar fibromatosis) are rare and can be diagnosed with histologic correlation only.

    Avagliano, Laura; Bulfamante, Gaetano Pietro; Massa, Valentina

    2017-06-01

    Cornelia de Lange syndrome (CdLS) is an inherited condition with a wide spectrum of phenotypic anomalies, consisting mainly of growth impairment, multi-organ abnormalities, and neurocognitive delay. Clinical diagnostic criteria after birth are well defined, whereas when to suspect the syndrome during intrauterine life still remains undefined. This review summarizes the main possible prenatal findings in CdLS, suggesting that a skilled ultrasound scan in cases of intrauterine growth restriction associated with other fetal abnormalities may improve the chance of prenatal diagnosis of CdLS, especially in families known to be at high risk. We propose that, following a sequence of detailed scans and examinations, CdLS affected fetuses could be diagnosed in utero, when one or more conditions (among them, intrauterine growth restriction, limb defects, facial abnormalities, diaphragmatic hernia, and heart diseases) are detected, and possibly confirmed by specific molecular testing.

    2008-11-01

    The present article critically discusses diagnosing borderline personality, demonstrating ideas raised with a treated case. In contrast to routine diagnoses made by psychiatrists according to common diagnosing systems (such as the American DSM or the WHO's ICD), we wonder whether this diagnosis reflects a medico-social construct, which is associated to the female status in masculine (or even patriarch) society, and probably associated even to the context of a woman diagnosed by a psychiatric system. In the context of critically viewing aetiological hypotheses to borderline personality (presented in our former article as a personality constellated around complex and prolonged trauma) in this article we suggest viewing borderline behaviours and symptoms as manifestations of coping and survival of a woman-victim in abusing surroundings.

    The contribution under consideration reports on the total deposition of anthropogenic emitted oxidized sulphur compounds, oxidized nitrogen compounds and reduced nitrogen compounds based on the emission prognosis of the BMU/UBA project 'Strategies for the reduction of the fine dust pollution for the year 2020. The emission prognoses are the fundament for the calculations with the LOTOS-EUROS model. The changes of the total deposition for sulphur compounds as well as nitrogen compounds between the years 2005 and 2020 are not large. For example, the total deposition of oxidized sulphur compounds from anthropogenic sources in the year 2020 is about 35% larger in comparison to the year 2005. In comparison to the year 2005, the total deposition of oxidized nitrogen compounds from anthropogenic sources in the year 2020 is about 21% larger.

    AIM: To investigate the accuracy of endoscopic or biopsy diagnoses of superficial nonampullary duodenal epithelial tumors (NADETs). METHODS: Clinicopathological data were reviewed for 84 superficial NADETs from 74 patients who underwent surgery or endoscopic resection between September 2002 and August 2014 at a single prefectural cancer center. Superficial NADETs were defined as lesions confined to the mucosa or submucosa. Demographic and clinicopathological data were retrieved from charts, endoscopic and pathologic reports. Endoscopic reports included endoscopic diagnosis, location, gross type, diameter, color, and presence or absence of biopsy. Endoscopic diagnoses were made by an endoscopist in charge of the examination before biopsy specimens were obtained. Endoscopic images were obtained using routine, front-view, high-resolution video endoscopy, and chromoendoscopy with indigocarmine was performed for all lesions. Endoscopic images were reviewed by at least two endoscopists to assess endoscopic findings indicative of carcinoma. Preoperative diagnoses based on endoscopy and biopsy findings were compared with histological diagnoses of resected specimens. Sensitivity, specificity, and accuracy were assessed for endoscopic diagnosis and biopsy diagnosis. RESULTS: The majority (81%) of the lesions were located in the second portion of the duodenum. The median lesion diameter was 14.5 mm according to final histology. Surgery was performed for 49 lesions from 39 patients, and 35 lesions from 35 patients were endoscopically resected. Final histology confirmed 65 carcinomas, 15 adenomas, and 3 hyperplasias. A final diagnosis of duodenal carcinoma was made for 91% (52/57) of the lesions diagnosed as carcinoma by endoscopy and 93% (42/45) of the lesions diagnosed as carcinoma by biopsy. The sensitivity, specificity, and accuracy of endoscopic diagnoses were 80%, 72%, and 78%, respectively, whereas those of biopsy diagnoses were 72%, 80%, and 74%, respectively

    Clinical data were collected in 194 cases of jaundiced patients treated at the "Adolfo Lopez Mateos" ISSSTE Hospital in Mexico City from July 1985 to July 1986. A copy of the clinical history of each patient was given to each of four physicians--one recently graduated from medical school, another in his first year of gastroenterology, and two others who were experienced gastroenterologists. The same clinical data were processed by a computer set up to use a modified Danish COMIC algorithm. All physicians and the computer technician were blinded to the "gold standard" pathologic diagnoses, with which their diagnoses were compared. Accuracy rates of the physicians in distinguishing intrahepatic (medical) from extrahepatic (surgical) jaundice were 78%, 86%, 86%, and 91%, and the accuracy of computer-assisted diagnoses was 96%. Chi-squared analysis of the diagnoses of three of the physicians and those of the computer showed significant differences (p between 0.1 and 0.01). For the diagnoses of the remaining physician, however, no significant difference was found after chi-squared continuity correction.

    2015-01-01

    Diagnosing death and issuing a Death Diagnosing Form (DDF) represents an activity that carries a great deal of public responsibility for medical professionals of the Emergency Medical Services (EMS) and is perpetually exposed to the control of the general public. Diagnosing death is necessary so as to confirm true, to exclude apparent death and consequentially to avoid burying a person alive, i.e. apparently dead. These expert-methodological guidelines based on the most up-to-date and medically based evidence have the goal of helping the physicians of the EMS in accurately filling out a medical report on diagnosing death. If the outcome of applied cardiopulmonary resuscitation measures is negative or when the person is found dead, the physician is under obligation to diagnose death and correctly fill out the DDF. It is also recommended to perform electrocardiography (EKG) and record asystole in at least two leads. In the process of diagnostics and treatment, it is a moral obligation of each Belgrade EMS physician to apply all available achievements and knowledge of modern medicine acquired from extensive international studies, which have been indeed the major theoretical basis for the creation of these expert-methodological guidelines. Those acting differently do so in accordance with their conscience and risk professional, and even criminal sanctions.

    Data from the National Health Interview Survey •Among adults aged 18 and over with diagnosed diabetes, 61.6% had an influenza vaccine in the past year. •A total of 52.6% of adults with diagnosed diabetes had a pneumococcal vaccine and 17.1% had the 3-dose vaccination schedule for hepatitis B at some point in the past. •Among adults aged 60 and over with diagnosed diabetes, 27.2% had ever had a shingles vaccine. •Among those with diagnosed diabetes, the vaccination coverage for influenza, pneumococcal, and shingles was lowest among poor adults, increased with age, and varied by race and ethnicity. •Hepatitis B vaccination coverage was lowest among poor adults, and it decreased with age. Persons with diabetes are at an increased risk for complications from vaccine-preventable infections (1-3). Several vaccines are recommended for adults with diabetes, including annual vaccination for influenza and at least a one-time dose of pneumococcal vaccine, regardless of age; a shingles vaccine starting at age 60; and a hepatitis B vaccine soon after diabetes diagnosis among those aged 19-59, and based on clinical discretion thereafter (4). This report describes the receipt of select vaccinations among adults with diagnosed diabetes by sex, age, race and ethnicity, and poverty status.

    2017-03-01

    A novel terahertz (THz) otoscope is designed and fabricated to help physicians to diagnose otitis media (OM) with both THz diagnostics and conventional optical diagnostics. The inclusion of indium tin oxide (ITO) glass in the THz otoscope allows physicians to diagnose OM with both THz and conventional optical diagnostics. To determine THz diagnostics for OM, we observed reflection signals from samples behind a thin dielectric film and found that the presence of water behind the membrane could be distinguished based on THz pulse shape. We verified the potential of this tool for diagnosing OM using mouse skin tissue and a human tympanic membrane samples prior to clinical application. The presence of water absorbed by the human membrane was easily distinguished based on differences in pulse shapes and peak-to-peak amplitudes of reflected THz pulses. The potential for early OM diagnosis using the THz otoscope was confirmed by alteration of THz pulse depending on water absorption level.

    There have been several reports describing rectovaginal fistula development after bevacizumab treatment, and these fistulas were diagnosed by CT scan or colonoscopy. We report a case of sigmoid-vaginal fistula diagnosed by fistulography. The case is a 53-year-old woman who was treated for chronic myelogenous leukaemia and gynaecological cancers 8 years previously. At 52 years of age, she was diagnosed with colon cancer and had a partial colectomy performed. One year after surgery, colon cancer recurred, and she was treated with anticancer agents, including bevacizumab. During chemotherapy, she complained of a foul smelling discharge from the vagina. Fistulography revealed a sigmoid-vaginal fistula. This is the first report of vaginal fistulography performed on a patient who was treated with bevacizumab. Fistulography may be useful for detecting sigmoid-vaginal fistula. © 2016 John Wiley & Sons Ltd.

    2013-01-01

    Full Text Available In control theory of discrete event systems (DESs, one of the challenging topics is the extension of theory of finite-state DESs to that of infinite-state DESs. In this paper, we discuss verification of opacity and diagnosability for infinite-state DESs modeled by pushdown automata (called here pushdown systems. First, we discuss opacity of pushdown systems and prove that opacity of pushdown systems is in general undecidable. In addition, a decidable class is clarified. Next, in diagnosability, we prove that under a certain assumption, which is different from the assumption in the existing result, diagnosability of pushdown systems is decidable. Furthermore, a necessary condition and a sufficient condition using finite-state approximations are derived. Finally, as one of the applications, we consider data integration using XML (Extensible Markup Language. The obtained result is useful for developing control theory of infinite-state DESs.

  9. Psychiatric diagnoses are not mental processes: Wittgenstein on conceptual confusion.

    Science.gov (United States)

    Rosenman, Stephen; Nasti, Julian

    2012-11-01

    Empirical explanation and treatment repeatedly fail for psychiatric diagnoses. Diagnosis is mired in conceptual confusion that is illuminated by Ludwig Wittgenstein's later critique of philosophy (Philosophical Investigations). This paper examines conceptual confusions in the foundation of psychiatric diagnosis from some of Wittgenstein's important critical viewpoints. Diagnostic terms are words whose meanings are given by usages not definitions. Diagnoses, by Wittgenstein's analogy with 'games', have various and evolving usages that are connected by family relationships, and no essence or core phenomenon connects them. Their usages will change according to the demands and contexts in which they are employed. Diagnoses, like many psychological terms, such as 'reading' or 'understanding', are concepts that refer not to fixed behavioural or mental states but to complex apprehensions of the relationship of a variety of behavioural phenomena with the world. A diagnosis is a sort of concept that cannot be located in or explained by a mental process. A diagnosis is an exercise in language and its usage changes according to the context and the needs it addresses. Diagnoses have important uses but they are irreducibly heterogeneous and cannot be identified with or connected to particular mental processes or even with a unity of phenomena that can be addressed empirically. This makes understandable not only the repeated failure of empirical science to replicate or illuminate genetic, neurophysiologic, psychic or social processes underlying diagnoses but also the emptiness of a succession of explanatory theories and treatment effects that cannot be repeated or stubbornly regress to the mean. Attempts to fix the meanings of diagnoses to allow empirical explanation will and should fail as there is no foundation on which a fixed meaning can be built and it can only be done at the cost of the relevance and usefulness of diagnosis.

    Results: A total of 36 cases were studied, of which diagnostic material was adequately obtained in 32 cases (88.88%. The sensitivity (92.85% and specificity (94.44% of FNAC were high, with an accuracy of 93.75%, which is similar to findings in other studies. Conclusion: FNAC plays a vital role in diagnosing bone tumors. It is a rapid, easy, cheap, and minimum invasive outpatient department procedure. However histopathology is still important in diagnosing bone tumors that are unclear or undiagnosed on FNAC since histopathology gives a complete architectural pattern of tissue.

    Traumatic lumbar hernia describes the extrusion of intraperitoneal or extraperitoneal contents through a defect in the posterolateral abdominal wall caused by a trauma. This is a rare entity and usually diagnosed by computed tomography. A 64-year-old male received an injury on his cervical spinal cord after an accident in which he fell down. He complained of a mass on his left posterolateral back area. We diagnosed the mass as a traumatic lumbar hernia by ultrasonography and confirmed it by computed tomography. We conclude that the ultrasonography can be a useful diagnostic tool for traumatic lumbar hernia

    Background The best indicator of the impact of human immunodeficiency virus (HIV) prevention programs is the incidence of infection; however, HIV is a chronic infection and HIV diagnoses may include infections that occurred years before diagnosis. Alternative methods to estimate incidence use diagnoses, stage of disease, and laboratory assays of infection recency. Using a consistent, accurate method would allow for timely interpretation of HIV trends. Objective The objective of our study was to assess the recent progress toward reducing HIV infections in the United States overall and among selected population segments with available incidence estimation methods. Methods Data on cases of HIV infection reported to national surveillance for 2008-2013 were used to compare trends in HIV diagnoses, unadjusted and adjusted for reporting delay, and model-based incidence for the US population aged ≥13 years. Incidence was estimated using a biomarker for recency of infection (stratified extrapolation approach) and 2 back-calculation models (CD4 and Bayesian hierarchical models). HIV testing trends were determined from behavioral surveys for persons aged ≥18 years. Analyses were stratified by sex, race or ethnicity (black, Hispanic or Latino, and white), and transmission category (men who have sex with men, MSM). Results On average, HIV diagnoses decreased 4.0% per year from 48,309 in 2008 to 39,270 in 2013 (P<.001). Adjusting for reporting delays, diagnoses decreased 3.1% per year (P<.001). The CD4 model estimated an annual decrease in incidence of 4.6% (P<.001) and the Bayesian hierarchical model 2.6% (P<.001); the stratified extrapolation approach estimated a stable incidence. During these years, overall, the percentage of persons who ever had received an HIV test or had had a test within the past year remained stable; among MSM testing increased. For women, all 3 incidence models corroborated the decreasing trend in HIV diagnoses, and HIV diagnoses and 2 incidence

The aim of the study was to evaluate the incidence of dual/triple diagnoses with alcohol dependent patients and to incorporate the diagnostic procedures in rutine work and in treatment planning.Material and methods. We were following the basic parameters of treatment of 469 patients (366 male, 102 female from July 1999 to July 2001. The diagnostic criteria according to ICD-10 were applied after at least four weeks of sobriety.Results. The most frequent additional diagnoses found were nicotine dependency, depressive and personal disorders. Main gender differences were found in diagnosis of depressive disorders and in dependency or abuse of prescripted drugs. Comparison of our results with literature data showed the greatest differences in diagnoses of cognitive, depressive, anxious data and dependency of other psychoactive substances.Conclusions. The comparison between the two time periods shows that stuff sensibility to diagnostic procedures of comorbidity states influences the frequency of diagnostic categories. The literature data review leads to impression of inconsistent diagnosing regarding the context and phylosophy of treatment context, stuff education and patient population.

    Rühli, F J; Ikram, S

    2014-02-01

    King Tutankhamun is one of the most famous rulers of antiquity,thus it is not surprising that a plethora of scientific studies have put forth possible medical diagnoses and causes of his death. Diseases(autologous or infectious), metabolic disorders, trauma (possibly even murder-related), or tumorous conditions have been postulated, frequently only based on secondary data sources. The aim of this article is to critically review all these diagnoses. Since the initial examination of the mummy in the mid 1920s by Howard Carter and others, several dozens of medical diagnoses based on various levels of evidence have been proposed. While some studies did not support any sign of a major disease, others suggested diseases whose existence cannot be proven with the little tissue that is preserved for study. In the last c. five years new examinations of the mummy were performed by computed tomography and ancient DNA analyses,now allowing not only to exclude certain diagnoses that had been postulated earlier, but also to arrive at new theories with a higher degree of certainty concerning the state of health and the early death of this most famous ruler.

    Miyamaru, Satoru; Haba, Koichi

    2014-01-01

    We report a case of chondrosarcoma of the larynx, diagnosed by a percutaneous core-needle biopsy (CNB). Cartilaginous tumors of the larynx are usually diagnosed by biopsy with direct laryngomicroscopy under general anesthesia. However, patients find it difficult to undergo a biopsy under general anesthesia, for physical, economic, and social reasons. Instead, we can readily detect and sample tumors of the larynx using ultrasound under local anesthesia with reduced stress. Concerning needle-puncture biopsies, including fine-needle aspiration cytology (FNAC) and CNB, some studies have reported needle track dissemination, a possible complication in patients with malignant tumors. Thus, in the head and neck region, we generally use FNAC for biopsies, not CNB. However, it can be difficult to diagnose bone tumors by cytology alone. Regarding primary bone tumors, only one study has reported needle track dissemination by CNB, in osteosarcoma of the femur. Additionally, this complication has not been reported before with chondrosarcoma anywhere in the body. To our knowledge, this is the first report concerning chondrosarcoma of the larynx diagnosed by percutaneous CNB. We recommend CNB as a useful and safe diagnostic technique for primary bone tumors in the head and neck region.

    Full Text Available Objective. Identify the profile of nursing diagnoses in patients with respiratory disorders. Methodology. A descriptive and cross-sectional study involving 38 patients with respiratory problems, of referral hospitals, in a city in northeastern Brazil, in the period from August to October, 2012. Data collection was performed using a form and diagnostic inference was made according with the Taxonomy II of NANDA I. Results. The average age of the patients was 46 years and males predominated (60.5%. The most frequent nursing diagnoses were: Risk for infection (97.3%, Acute pain (68.4%, Poor knowledge (68.4%, Sedentary lifestyle (65.7%, Ineffective airway clearance (65.7%, Risk-prone health behavior (63.1%, Activity intolerance (52.6% and Disturbed sleep pattern (33.3%. Evaluated patients exhibited an average of 8.6 nursing diagnoses (SD = 2.8. With respect to the defining characteristics and related factors the average per person was 7.2 and 9.3, respectively. Conclusion. In this group of patients the most frequent diagnoses were the domain activity/rest. Knowledge of nursing diagnoses profile presented by people with respiratory disorders is important, because it is part of the Nursing Process and nurses who take care of such patients should exercise them in their care practice. Knowledge of the mains nursing diagnosis presented by patients with respiratory disorders are important for the practice of nurses who care for these patients, because it allows the choice of responses to problems of their clientele.

  12. Commentary: the problem of agreement on diagnoses in criminal cases.

    Patterson, Raymond F

    2010-01-01

    The authors present an important two-part study as they strive to provide an empirical analysis of psychiatric diagnoses in criminal case reports in Australia. In the first part, they compare the level of agreement or correlation of diagnoses between pairs of experts who prepared reports for either the prosecution or defense with other reports prepared for the same and opposing sides and by profession (i.e., psychiatrists and/or psychologists). In the second part, they compare the level of agreement or correlation between experts retained by either the prosecution or defense and treating practitioners. Psychiatric diagnoses are fundamental requirements that may affect the adjudication of criminal and civil cases. Both parts of the study focus on criminal cases and are very exciting in that they review not only the correlation of agreements in these areas but also address indirectly the concept of the so-called hired gun. The development of specialized expertise in the evaluation and assessment of defendants by designated opinion or expert witnesses has progressed over time. The nexus between psychiatry and the law (i.e., forensic psychiatry) has included the presentation of psychiatric diagnosis to the courts and the necessity for the expert or treating practitioner to address legal questions raised by the court. This study makes important steps in the direction of examining and analyzing the role of psychiatric diagnosis according to the responsibilities of the evaluator (i.e., as independent examiner or treating practitioner), as well as the possible influence of professional training and experience on differences in diagnoses between two evaluators. It is anticipated that there will be further work in these areas to address not only diagnoses but forensic recommendations and opinions.

    Research shows transgender individuals experience pronounced health disparities compared with their nontransgender peers. Yet, there remains insufficient research about health differences within transgender populations. This study seeks to fill this gap by exploring how current urban/rural status is associated with lifetime diagnosis of mood disorder, alcohol dependence disorder, illicit drug abuse disorder, tobacco use, posttraumatic stress disorder, human immunodeficiency virus, and suicidal ideation or attempt among veterans with transgender-related diagnoses. This study used a retrospective review of The Department of Veterans Affairs (VA) administrative data for transgender patients who received VA care from 1997 through 2014. Transgender patients were defined as individuals that had a lifetime diagnosis of any of 4 International Classification of Diseases-9 diagnosis codes associated with transgender status. Independent multivariable logistic regression models were used to explore associations of rural status with medical conditions. Veterans with transgender-related diagnoses residing in small/isolated rural towns had increased odds of tobacco use disorder (adjusted odds ratio=1.39; 95% confidence intervals, 1.09-1.78) and posttraumatic stress disorder (adjusted odds ratio=1.33; 95% confidence intervals, 1.03-1.71) compared with their urban transgender peers. Urban/rural status was not significantly associated with other medical conditions of interest. This study contributes the first empirical investigations of how place of residence is associated with medical diagnoses among veterans with transgender-related diagnoses. The importance of place as a determinant of health is increasingly clear, but for veterans with transgender-related diagnoses this line of research is currently limited. The addition of self-reported sex identity data within VA electronic health records is one way to advance this line of research.

    Full Text Available Abstract Background The demand for complementary medicine (CM is growing worldwide and so is the supply. So far, there is not much insight in the activities in Dutch CM practices nor in how these activities differ from mainstream general practice. Comparisons on diagnoses and visit length can offer an impression of how Dutch CM practices operate. Methods Three groups of regularly trained physicians specialized in CM participated in this study: 16 homeopathic physicians, 13 physician acupuncturists and 11 naturopathy physicians. Every CM physician was asked to include a maximum of 75 new patients within a period of six months. For each patient an inclusion registration form had to be completed and the activities during a maximum of five repeat visits were subsequently registered. Registrations included patient characteristics, diagnoses and visit length. These data could be compared with similar data from general practitioners (GPs participating in the second Dutch national study in general practice (DNSGP-2. Differences between CM practices and between CM and mainstream GP data were tested using multilevel regression analysis. Results The CM physicians registered activities in a total of 5919 visits in 1839 patients. In all types of CM practices general problems (as coded in the ICPC were diagnosed more often than in mainstream general practice, especially fatigue, allergic reactions and infections. Psychological problems and problems with the nervous system were also diagnosed more frequently. In addition, each type of CM physician encountered specific health problems: in acupuncture problems with the musculoskeletal system prevailed, in homeopathy skin problems and in naturopathy gastrointestinal problems. Comparisons in visit length revealed that CM physicians spent at least twice as much time with patients compared to mainstream GPs. Conclusions CM physicians differed from mainstream GPs in diagnoses, partly related to general and partly to

    Reported prevalence rates of chronic rhinosinusitis (CRS) range from 1% to 12% worldwide. To facilitate appropriate health service delivery and resource allocation, it is important to improve the estimated burden of CRS to the health care system. To assess the prevalence and incidence of diagnosed CRS in Alberta, Canada, from the perspective of the health care system and to evaluate the 10-year temporal trend and geographic variation of diagnosed CRS. From provincial-wide physicians' claim data, a CRS cohort was identified using a validated case definition. The population at the midpoint (2008-2009) of the study period (2 925 930) was used as the reference. The crude as well as age- and sex-standardized incidence and prevalence rates were calculated. The age-specific incidence and prevalence by sex were also assessed in each study year. Small-area variation analysis was conducted using extremal quotient, weighted coefficient of variation, χ2 statistic, systematic component of variation, and empirical Bayes variance estimate. Of the 2 925 930 individuals in the study at midpoint (2008-2009), 1 451 261 (49.6%) were women, and the mean (SD) age was 45 (17) years. From fiscal year 2004-2005 to fiscal year 2013-2014, the mean age- and sex-standardized incidence of diagnosed CRS was 2.5 (range, 2.3-2.7) per 1000 population. The estimated prevalence based on age-specific incidence varied between 18.8 (95% CI, 18.7-18.9) and 23.3 (95% CI, 23.1-23.5) per 1000 population during 2004-2005 to 2013-2014, and no obvious growing trend was found. There was high geographic variation in the diagnosed incidence and prevalence of CRS (mean systematic component of variation, 19.4 and 12.3, respectively). Although the incidence and prevalence rates of diagnosed CRS were lower compared with earlier published estimates obtained from population-based survey analysis, outcomes from this study may more accurately reflect the disease burden of CRS to the health care system. Given

    2010-01-01

    Full Text Available Technologically advanced materials, such as alloys of aluminum, nickel or titanium are currently used increasingly often in significantly loaded components utilized in the aviation industry, among others in the construction of jet turbine engine blades. The article presents a method for diagnosing the condition of the inside of cast blades with the use of laser ultrasonography. The inspection is based on finding hidden flaws with a size of between 10 and 30μm. Laser ultrasonography offers a number of improvements over the non-destructive methods used so far, e.g. the possibility to diagnose the cast on a selected depth, high signal-to-noise ratio and good sensitivity. The article includes a brief overview of non-destructive inspection methods used in foundry engineering and sample results of inspecting the inner structure of a turbo jet engine blade using the method described in the article.

  17. A new gauge-invariant method for diagnosing eddy diffusivities

    CERN Document Server

    Mak, Julian; Marshall, David P

    2015-01-01

    Coarse resolution numerical ocean models must typically include a parameterisation for mesoscale turbulence. A common recipe for such parameterisations is to invoke down-gradient mixing, or diffusion, of some tracer quantity, such as potential vorticity or buoyancy. However, it is well known that eddy fluxes include large rotational components which necessarily do not lead to any mixing; eddy diffusivities diagnosed from unfiltered fluxes are thus contaminated by the presence of these rotational components. Here a new methodology is applied whereby eddy diffusivities are diagnosed directly from the eddy force function. The eddy force function depends only upon flux divergences, is independent of any rotational flux components, and is inherently non-local and smooth. A one-shot inversion procedure is applied, minimising the mis-match between parameterised force functions and force functions derived from eddy resolving calculations. This enables diffusivities associated with the eddy potential vorticity and buo...

    This article focuses on a discussion of diagnosing, special education, and ‘learnification’ in a Danish school context in which the increasing use of diagnosis is analysed as resulting from the ideas of normality that are associated with the construction of the pupil as a learner. I argue...... that diagnosis in schools can be seen as the shadow side of the articulation and management of learning through schools’ requirements for pupils. This article is based on my analysis of files produced by educational psychologists. Learning and diagnosis, I argue, constitute two different, but parallel, ways...... of looking at being a pupil in school, each of which represents conceptions of deviance and normality.

    2001-01-01

    Based on the moiré effect and the Fresnel diffraction theory, a novel technique for diagnosing the beam properties is presented and analyzed, which is especially suitable for X-ray lasers. The method makes it possible, in a one-shot experimental measurement, to determine the beam quality factor M2, the effective radius of curvature, the beam width, the far-field divergence, and the waist location and radius as well as the spatial coherence and its evolution. Numerical simulation proves the validity of the method. Note that the novel moiré technique opens an efficient road, for the first time, to fully diagnose the spatial properties of X-ray lasers.

    Full Text Available We report the first case of Ramsay Hunt syndrome (RHS diagnosed after kidney transplantation in Korea. RHS is a disease caused by latent varicella-zoster characterized to involve geniculate ganglion of the seventh cranial nerve. Patients who have undergone kidney transplantation can be easily affected by viral infections because of their immune-compromised status. A 35-year-old man with hypertensive end-stage renal disease underwent kidney transplantation. Two months after surgery, the recipient was diagnosed with RHS and treated with antivirals and steroids. However, after using the antiviral agents for the recommended duration, facial paralysis occurred as a new presentation and he required further treatment. Otalgia and periauricular vesicles improved, but the facial palsy remained.

    Polymerase chain reaction (PCR) has been applied in diagnosing amebic liver infection by detecting pathogenic Entamoeba histolytica DNA in liver aspirates. Oligonucleotide primers found to he specific for the gene encoding the 30 kDa molecule of this pathogenic ameba were used in the test. Liver aspirates obtained from 23 patients with amebic liver abscess substantiated by typical clinical rnanifastation or with very high titres of anti-E histtolytica antibodies by ELISA were found to he positive by PCR. Fourteen controlsamples (3 cases of bacterial liver abscess, I of liver cancer and 10 of other abscess) were all found to be negative to this reaction. The results suggested PCR to he a specific and sensitive tool for diagnosing amebic liver abscess infections.

    Cholecystocolonic fistula is an uncommon potential complication of cholecystitis found intraoperatively in 0.06-0.14 % of patients undergoing cholecystectomy and 0.1-0.5 % of autopsy series. Although cholecystocolonic fistula is the second most common cholecystoenteric fistula, second only to cholecystoduodenal fistula, it is diagnosed preoperatively in only 7.9 % of patients. Failure to preoperatively diagnose cholecystocolonic fistula places surgeons in precarious positions, as they may be forced to convert a seemingly routine cholecystectomy to a more sophisticated procedure coupled with adhesiolysis, colonic suturing, or colonic resection. We report a young patient who presented to the emergency department with complaints indicative of acute cholecystitis; however, preoperative ultrasound was suggestive of a cholecystoenteric fistula. Computed tomography and pathology were pathognomonic with clear visualization of the cholecystocolonic fistulous tract.

    Despite the essential role of insulin in the management of patients with insulin deficiency, insulin use can lead to adverse effects such as hypoglycaemia and weight gain. Rarely, crucial fluid retention can occur with insulin therapy, resulting in an oedematous condition. Peripheral or generalised oedema is an extremely rare complication of insulin therapy in the absence of heart, liver or renal involvement. It has been reported in newly diagnosed type 1 diabetes, in poorly controlled type 2 diabetes following the initiation of insulin therapy, and in underweight patients on large doses of insulin. The oedema occurs shortly after the initiation of intensive insulin therapy. We describe two adolescent girls with newly diagnosed type 1 diabetes, who presented with oedema of the lower extremities approximately one week after the initiation of insulin treatment; other causes of oedema were excluded. Spontaneous recovery was observed in both patients. Conflict of interest:None declared. PMID:21274337

    Between 1959 and 1987, the psychiatric evaluation of astronaut candidates evolved from a 30-h intensive examination evaluating applicants for psychopathology, and studying their performance under stress, to a 2-h clinical interview whose structure and contents were determined by the individual examiner. Evaluations done during these years applied both psychiatric (or, 'select-out') criteria and psychological (or, 'select-in') criteria. In an attempt to more rigorously define the psychiatric, 'select-out' component, a standardized, semistructured clinical interview was developed to identify the presence or history of psychiatric disorders listed in the Diagnostic and Statistical Manual of Mental Disorders, 3rd Ed. ('DSM-III'). A total of 117 astronaut applicants underwent this clinical interview as part of a comprehensive medical evaluation during a recent astronaut selection. Of the 117 applicants, 9 (7.7 percent) met DSM-III criteria for a variety of Axis I and Axis II diagnoses, including V-code diagnoses.

    Elite athletes have a high prevalence of asthma and exercise-induced bronchoconstriction. Although respiratory symptoms can be suggestive of asthma, the diagnosis of asthma in elite athletes cannot be based solely on the presence or absence of symptoms; diagnosis should be based on objective...... measurements, such as the eucapnic voluntary hyperpnea test or exercise test. When considering that not all respiratory symptoms are due to asthma, other diagnoses should be considered. Certain regulations apply to elite athletes who require asthma medication for asthma. Knowledge of these regulations...... is essential when treating elite athletes. This article is aimed at physicians who diagnose and treat athletes with respiratory symptoms. It focuses on the pathogenesis of asthma and exercise-induced bronchoconstriction in elite athletes and how the diagnosis can be made. Furthermore, treatment of elite...

  9. Challenges in diagnosing infection in the diabetic foot.

    2015-06-01

    Diagnosing the presence of infection in the foot of a patient with diabetes can sometimes be a difficult task. Because open wounds are always colonized with microorganisms, most agree that infection should be diagnosed by the presence of systemic or local signs of inflammation. Determining whether or not infection is present in bone can be especially difficult. Diagnosis begins with a history and physical examination in which both classic and 'secondary' findings suggesting invasion of microorganisms or a host response are sought. Serological tests may be helpful, especially measurement of the erythrocyte sedimentation rate in osteomyelitis, but all (including bone biomarkers and procalcitonin) are relatively non-specific. Cultures of properly obtained soft tissue and bone specimens can diagnose and define the causative pathogens in diabetic foot infections. Newer molecular microbial techniques, which may not only identify more organisms but also virulence factors and antibiotic resistance, look very promising. Imaging tests generally begin with plain X-rays; when these are inconclusive or when more detail of bone or soft tissue abnormalities is required, more advanced studies are needed. Among these, magnetic resonance imaging is generally superior to standard radionuclide studies, but newer hybrid imaging techniques (single-photon emission computed tomography/computed tomography, positron emission tomography/computed tomography and positron emission tomography/magnetic resonance imaging) look to be useful techniques, and new radiopharmaceuticals are on the horizon. In some cases, ultrasonography, photographic and thermographic methods may also be diagnostically useful. Improved methods developed and tested over the past decade have clearly increased our accuracy in diagnosing diabetic foot infections.

    To explore the reliability and accuracy of lung ultrasound for diagnosing neonatal pneumothorax. This study was divided into two phases. (1) In the first phase, from January 2013 to June 2015, 40 patients with confirmed pneumothorax had lung ultrasound examinations performed to identify the sonographic characteristics of neonatal pneumothorax. (2) In the second phase, from July 2015 to August 2016, lung ultrasound was undertaken on 50 newborn infants with severe lung disease who were suspected of having pneumothorax, to evaluate the sonographic accuracy and reliability to diagnose pneumothorax. (1) The main ultrasonic manifestations of pneumothorax are as follows: ① lung sliding disappearance, which was observed in all patients (100%); ② the existence of the pleural line and the A-line, which was also observed in all patients (100%); ③ the lung point, which was found in 75% of the infants with mild-moderate pneumothorax but not found to exist in 25% of the severe pneumothorax patients; ④ the absence of B-lines in the area of the pneumothorax (100% of the pneumothorax patients); and ⑤ no lung consolidation existed in the area of the pneumothorax (100% of the pneumothorax patients). (2) The accuracy and reliability of the lung sonographic signs of lung sliding disappearance as well as the existence of the pleural line and the A-line in diagnosing pneumothorax were as follows: 100% sensitivity, 100% specificity, 100% positive predictive value, and 100% negative predictive value. When the lung point exists, the diagnosis is mild-moderate pneumothorax, whereas if no lung point exists, the diagnosis is severe pneumothorax. Lung ultrasound is accurate and reliable in diagnosing and ruling out neonatal pneumothorax and, in our study, was found to be as accurate as chest X-ray. Copyright © 2017 Elsevier Inc.

    Full Text Available Background: How to manage a late diagnosed Hirschsprung′s disease (HD and how to avoid calibre discrepancy? Subjects and Methods: A retrospective study of all patients diagnosed with HD over 2 years in our hospital from January 2009 to December 2012. Data were analysed for clinical presentations, investigations, surgical procedures and post-operative outcome. Results: Fifteen patients, operated by one single surgeon, were included in this study. The mean age was 6 years (2-16 years. Patients had an ultra-short segment type in 4 cases, rectosigmoid type in 9 cases and descending colonic aganglionosis in 2 cases. Rectal wash out was effective in 12 patients. A blowhole transverse colostomy was performed in 2 patients. Twelve patients underwent one single stage endorectal pull-through. Anastomosis incongruence was avoided by a plication procedure never described before. The assessment of post-operative outcomes by the paediatric incontinence and constipation scoring system revealed a normal continence function in all our patients, but 3 patients suffered from soiling secondary to constipation. Conclusion: One single stage pull-through can be safe and effective in children with late diagnosed HD. Routine rectal washout is a good way to prepare the colon. In some cases, blowhole colostomy can be an option. Anastomosis incongruence is a challenge; we describe a plication procedure to avoid it.

    Schwannomas are peripheral nerve tumors that are typically solitary and benign. Their diagnosis is largely based on surgically resected specimens. Recently, a number of case reports have indicated that retroperitoneal schwannomas could be diagnosed with endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA)We report the diagnosis of three cases of schwannoma using EUS-FNA. Subjects weree two males and one fe-twomale,ages 22, 40, and 46 years, respectively, all of whom were symptom-free. Imaging findings showed well-circumscribed round tumors.However, as the tumors could not be diagnosed using these findings alone, EUS-FNA was performed. Hematoxylin-eosin staining of the resulting tissue fragments revealed bland spindle cells with nuclear palisading. There was no disparity in nuclear sizes.Immunostaining revealed S-100 protein positivity and all cases were diagnosed as schwannomas. Ki-67 indexes were 3%-15%,2%-3%,and 3%, respectively. No case showed any signs of malignancy.As most schwannomas are benign tumors and seldom become malignant, we observed these patients without therapy. All tumors demonstrated no enlargement and no change in characteristics.Schwannomasa are almost always benign and can be observed following diagnosis by EUS-FNA.

    Full Text Available Globally, heart disease is the leading cause of death for both men and women. One in every four people is afflicted with and dies of heart disease. Early and accurate diagnoses of heart disease thus are crucial in improving the chances of long-term survival for patients and saving millions of lives. In this research, an advanced ensemble machine learning technology, utilizing an adaptive Boosting algorithm, is developed for accurate coronary heart disease diagnosis and outcome predictions. The developed ensemble learning classification and prediction models were applied to 4 different data sets for coronary heart disease diagnosis, including patients diagnosed with heart disease from Cleveland Clinic Foundation (CCF, Hungarian Institute of Cardiology (HIC, Long Beach Medical Center (LBMC, and Switzerland University Hospital (SUH. The testing results showed that the developed ensemble learning classification and prediction models achieved model accuracies of 80.14% for CCF, 89.12% for HIC, 77.78% for LBMC, and 96.72% for SUH, exceeding the accuracies of previously published research. Therefore, coronary heart disease diagnoses derived from the developed ensemble learning classification and prediction models are reliable and clinically useful, and can aid patients globally, especially those from developing countries and areas where there are few heart disease diagnostic specialists.

    Gestational breast cancer (GBC) presents many challenges for women and the clinicians who care for them. The aim of this study was to explore the health care experiences of women diagnosed with GBC to inform and improve clinical care of women in this predicament. Semi-structured interviews were conducted with 17 women who had been diagnosed with GBC in the previous 5 years. The overarching themes for perceived quality of care were "communication" and "comprehensive care." "Communication" had two sub themes: "interdisciplinary communication" (the way health professionals from different disciplines communicated with each other about the management of the woman's care) and "patient communication" (how they communicated this to the woman). The "comprehensive care" theme incorporated three sub themes: "the spirit" (psychological care); "the mind" (information provision); and "the body" (management of treatment side effects). Women's own accounts of positive and negative experiences of GBC care provide unique and specific insights which improve understanding of their concerns and needs. The findings can inform advances in quality and efficacy of clinical care; offer guidance for obstetricians, oncologists and allied health professionals about the needs of women diagnosed with GBC and how care can be optimised; and inform the development of resources to assist women and their families.

    Network traffic anomalies are unusual changes in a network,so diagnosing anomalies is important for network management.Feature-based anomaly detection models (ab)normal network traffic behavior by analyzing packet header features. PCA-subspace method (Principal Component Analysis) has been verified as an efficient feature-based way in network-wide anomaly detection.Despite the powerful ability of PCA-subspace method for network-wide traffic detection,it cannot be effectively used for detection on a single link.In this paper,different from most works focusing on detection on flow-level traffic,based on observations of six traffc features for packet-level traffic,we propose a new approach B6SVM to detect anomalies for packet-level traffic on a single link.The basic idea of B6-SVM is to diagnose anomalies in a multi-dimensional view of traffic features using Support Vector Machine (SVM).Through two-phase classification,B6-SVM can detect anomalies with high detection rate and low false alarm rate.The test results demonstrate the effectiveness and potential of our technique in diagnosing anomalies.Further,compared to previous feature-based anomaly detection approaches,B6-SVM provides a framework to automatically identify possible anomalous types.The framework of B6-SVM is generic and therefore,we expect the derived insights will be helpful for similar future research efforts.

    2012-09-01

    Full Text Available Dysembryoplastic neuroepithelial tumor (DNT, described in 1988 and introduced in the WHO classification in 1993, affects predominantly children or young adults causing intractable complex partial seizures. Since it is benign and treated with surgical resection, its recognition is important. It has similarities with low-grade gliomas and gangliogliomas, which may recur and become malignant. OBJECTIVES: To investigate whether DNT was previously diagnosed as astrocytoma, oligodendroglioma, or ganglioglioma and to determine its frequency in a series of low-grade glial/glio-neuronal tumors. METHODS: Clinical, radiological, and histological aspects of 58 tumors operated from 1978 to 2008, classified as astrocytomas (32, including 8 pilocytic, oligodendrogliomas (12, gangliogliomas (7, and DNT (7, were reviewed. RESULTS: Four new DNT, one operated before 1993, previously classified as astrocytoma (3 and oligodendroglioma (1, were identified. One DNT diagnosed in 2002 was classified once more as angiocentric glioma. Therefore, 10 DNT (17.2% were identified. CONCLUSIONS: Clinical-radiological and histopathological correlations have contributed to diagnose the DNT.

    The aim of this study was to assess the ability of dental students in the screening clinic of the Kuwait University Dental Center to detect and diagnose oral mucosal lesions. Clinical examinations performed by dental students between January 2009 and February 2011 were included. All their findings regarding the oral mucosal lesions and dental carious lesions detected were recorded, after which the patients were re-examined by faculty examiners. The students rated their own ability to detect mucosal and carious lesions before each examination. Among the 341 patients screened, 375 oral mucosal lesions were found by the faculty examiners. Of those, the students detected 178 (47.5%). Out of the 375 lesions, including the ones they failed to detect, the students diagnosed 272 (72.5%) correctly. The students were more likely (p≤0.01) to correctly diagnose a mucosal lesion when they themselves had detected it (n=169/178) than when they failed to detect it and had it subsequently pointed out by the faculty examiners (n=103/197). The students were more competent in detecting carious lesions (p≤0.001) than in detecting mucosal lesions. A significantly higher proportion of students who felt confident in detecting mucosal lesions were actually more competent in detecting the lesions than those who were not confident (p≤0.001). Further educational strategies are needed to motivate Kuwait University dental students to develop the knowledge, skills, and judgment necessary to integrate a complete intraoral examination into their routine practice.

    2015-01-01

    Pilomatricomas can be confidently diagnosed cytologically due to their characteristic cytomorphological features. However, these lesions are rarely encountered by cytopathologists and thus pose a diagnostic dilemma to even experienced individuals, especially when the lesions are focally sampled. We describe two cases of histologically confirmed pilomatricoma. The first case is of a 13-year-old boy with posterior cervical 'lymphadenopathy', and the second one is of a 12-year-old girl with a lower cheek swelling. Both aspirates comprised predominantly atypical basal-like cells, with prominent nucleoli. 'Ghost cells' were readily identified by cell block in case two, but cell block in case one yielded no diagnostic material. In case two, pilomatricoma was accurately diagnosed pre-operatively. A cytological suspicion of a neoplastic process was raised in case one. Despite being diagnostically challenging, pilomatricoma can be diagnosed with careful observation of two unique cytological features of the lesions: (1) pathognomonic 'ghost cells' and (2) irregular, saw-toothed, loosely cohesive basaloid cells, with prominent nucleoli. The role of thorough sampling of the lesion, with multiple passes of various sites, cannot be overemphasized.

All the patients were neurophysiologicly tested. Results. Out of 181 patients, clinical findings were considered positive for CTS in 37 patients. The neurophysiological findings for CTS were positive in 60 patients. Both clinical and neurophysiological findings were positive in 31 patients and both findings were negative in 115 patients (sensitivity 0,51; specificity 0,95. Conclusion. Low sensitivity and high specificity suggest that it is easier to exclude rather than to accurately diagnose CTS based on clinical examination alone. Thus, there is the need for neurophysiological evaluation of patients with complains in the arm.

    Full Text Available Background: Infective endocarditis continues to challenge modern medicine despite its rare occurrence in the general population. Its incidence depends on risk groups. Correlation of anatomical and pathological findings with clinical and epidemiological elements may explain the current features of this condition. Objective: to describe the anatomical features of patients with infective endocarditis diagnosed at autopsy. Methods: A descriptive study including cases of infective endocarditis diagnosed at autopsy between 1986 and 2008 was conducted in the Provincial Clinical-Surgical Hospital Celia Sanchez, Granma. The variables analyzed were: age, sex, previous anatomical lesions, location of vegetations, multi-organ embolic infarcts and embolic abscesses, complications, culture of lesions and direct causes of death. Results: frequency of infective endocarditis diagnosed at necropsy ranged annually from 0.4 to 1.5%. Native valve endocarditis without previous damage was the most frequent. The anatomical findings were more common in the left side of the heart. Right-sided nosocomial endocarditis accounted for almost a third of the deceased patients and risk factors were identified. Embolic lesions affecting various organs, systemic complications and direct causes of death showed acute infectious endocarditis. The most common pathogen was Staphylococcus aureus. Conclusion: knowing the anatomical findings may contribute to the understanding of the clinical and epidemiological aspects of this condition. Correlation between anatomical and clinical findings was low; therefore difficulties in establishing the diagnosis during life are inferred.

    This article presents findings from a hermeneutic-phenomenological study with the aim to investigate the meaning of the lived experience of hope in women newly diagnosed with gynaecological cancer. Fifteen women were interviewed the day they were receiving the diagnosis at a gynaecological department of a Danish university hospital. The women, aged 24-87 (median 52 yrs), were diagnosed with ovarian, endometrial, cervical and vulvar cancer. Hope was found to be connected to both diagnosis, cure, family life and life itself and closely tied to hopelessness. The newly received cancer diagnosis made the women oscillate between hope and hopelessness, between positive expectations of getting cured and frightening feelings of the disease taking over. Five major interrelated themes of hope were identified: hope of being cured, cared for and getting back to normal, hope as being active and feeling well, hope as an internal power to maintain integration, hope as significant relationships and hope as fighting against hopelessness. Thus, hope was woven together with hopelessness in a mysterious way; it took command through inner strength and courage based on a trust in being cured and of being in relationship with significant others. The findings of the close relationship between the shades of hope and hopelessness support the need for nurses to continue to practice hope-inspiring nursing. Nurses need to understand the complexity of hope and its close connection to hopelessness when newly diagnosed with a threatening disease as cancer; and the findings might help nurses assist patients in fighting hopelessness.

    Studies are beginning to show the importance of appraisals to different types and severities of psychiatric disorders. Yet, little work in this area has assessed whether trauma-related appraisals can differentiate complex trauma-related disorders, such as posttraumatic stress disorder (PTSD) and dissociative identity disorder (DID). The current study evaluated whether any of 6 trauma-related appraisals distinguished adults diagnosed with DID from those diagnosed with PTSD. To accomplish this, we first examined the basic psychometric properties of a Dutch-translated short-form of the Trauma Appraisals Questionnaire (TAQ) in healthy control (n = 57), PTSD (n = 27) and DID (n = 12) samples. The short-form Dutch translation of the TAQ showed good internal reliability and criterion-related validity for all 6 subscales (betrayal, self-blame, fear, alienation, shame, anger). Of the 6 subscales, the alienation appraisal subscale specifically differentiated DID from PTSD, with the former group reporting more alienation. Abuse-related appraisals that emphasize disconnection from self and others may contribute to reported problems of memory and identity common in DID. The current findings suggest that addressing experiences of alienation may be particularly important in treatment for clients diagnosed with DID. (c) 2015 APA, all rights reserved).

    Laser therapy has become a routine procedure in dermatological practice and is frequently also used for pigmented lesions. Few reports exist of melanomas diagnosed in lesions previously treated by laser therapy. Between 2007 and 2014, we identified 11 patients who presented to our department with a melanoma diagnosed in a region previously treated by laser therapy. The course of events until the diagnosis of melanoma was assessed as well as patient outcome including treatment for disease progression. No histological assessment had been performed prior to laser therapy in nine of 11 (82%) cases. Benign melanocytic lesions had been diagnosed by biopsy prior to laser therapy in the other two cases. Time from laser therapy to diagnosis of melanoma ranged from less than 1 to 10 years. Stage of disease at diagnosis varied from stage IA to IIIC. Four patients progressed to stage IV disease, of whom at least one died of melanoma. We conclude that laser treatment of pigmented lesions can complicate the diagnosis of melanoma and lead to diagnosis delay with potentially fatal consequences. Considering this risk, we believe laser therapy for pigmented lesions should either be avoided entirely or at a minimum performed only after prior histological assessment. © 2016 Japanese Dermatological Association.

    Full Text Available Objective. Eating disorders commonly present with nonspecific findings, masquerading as other, more common etiologies of malnutrition and wasting. In low-prevalence populations, these ambiguities can complicate clinicians’ diagnostic reasoning, resulting in delayed or missed diagnoses. Method. We report the atypical case of a 51-year-old male with a five-year history of unexplained weight loss despite extensive past medical evaluation. Previous documentation of profound lymphopenia and bone marrow atrophy had not been linked to a known association with eating disorders. Results. Evaluation for medical etiologies of wasting was negative. Following psychiatric evaluation, the patient was diagnosed with an eating disorder, not otherwise specified, and admitted to a specialized nutritional rehabilitation program. Conclusion. The nonspecific clinical history, physical exam, and laboratory abnormalities of eating disorders can make these diagnoses challenging and delay appropriate treatment. Clinicians should consider eating disorders in patients with malnutrition, severe lymphopenias, and gelatinous marrow transformation early in their workup, so as to avoid potentially negative outcomes.

    To prospectively identify different coping strategies among newly diagnosed amyotrophic lateral sclerosis patients and whether they change over time and to determine whether physical function, psychological well-being, age and gender correlated with the use of different coping strategies. Amyotrophic lateral sclerosis is a fatal disease with impact on both physical function and psychological well-being. Different coping strategies are used to manage symptoms and disease progression, but knowledge about coping in newly diagnosed amyotrophic lateral sclerosis patients is scarce. This was a prospective study with a longitudinal and descriptive design. A total of 33 patients were included and evaluation was made at two time points, one to three months and six months after diagnosis. Patients were asked to complete the Motor Neuron Disease Coping Scale and the Hospital Anxiety and Depression Scale. Physical function was estimated using the revised Amyotrophic Lateral Sclerosis Functional Rating Scale. The most commonly used strategies were support and independence. Avoidance/venting and information seeking were seldom used at both time points. The use of information seeking decreased between the two time points. Men did not differ from women, but patients ≤64 years used positive action more often than older patients. Amyotrophic Lateral Sclerosis Functional Rating Scale was positively correlated with positive action at time point 1, but not at time point 2. Patients' psychological well-being was correlated with the use of different coping strategies. Support and independence were the most used coping strategies, and the use of different strategies changed over time. Psychological well-being was correlated with different coping strategies in newly diagnosed amyotrophic lateral sclerosis patients. The knowledge about coping strategies in early stage of the disease may help the nurses to improve and develop the care and support for these patients. © 2014 John Wiley

    Full Text Available Context An extramedullary plasmacytoma is a discrete collection of monoclonal plasmocytes arising in tissues other than the bone. Gastrointestinal involvement has been reported in approximately 10% of cases and usually involves the liver; however, there have been a number of cases involving the pancreas. Discussion Although helical CT can be used to diagnose pancreatic plasmacytomas based on a typical radiological appearance, there are a number of pitfalls with CT including similar radiologic appearances of other pancreatic tumors, malignant seeding induced by CT biopsy, and creation of multiple secondary plasmacytomas precipitated by CT biopsy. Tissue diagnosis is critical to management in pancreatic lesions as the decision to pursue surgery (pancreatic adenocarcinoma versus chemotherapy (lymphoma or radiation (extramedullary plasmacytoma is dependent on a correct tissue diagnosis. Tissue diagnosis can change morbidity and mortality with respect to specific treatment of pancreatic lesions in the milieu of pancreatic tumor variance. In the confirmed tissue diagnosis of pancreatic plasmacytoma, radiation and chemotherapy can be preferentially chosen over high risk surgery. EUS-FNA has a lower risk of malignant seeding, complications, and a high sensitivity in the diagnosis of pancreatic plasmacytomas, especially with an increased number of passes and bedside cytopathologists. Conclusion It is important for physicians to have a high index of suspicion for diagnosing pancreatic plasmacytomas in the appropriate clinical setting (i.e., a previously diagnosed multiple myeloma, extramedullary plasmacytoma or any other plasma cell neoplasm. EUS-FNA is now an indispensable imaging modality to achieve the diagnosis of pancreatic extramedullary plasmacytomas with an inherently lower rate of complications, and should be the first choice for tissue evaluation.

    Full Text Available The article presents an analysis of the existing approach to automobiles technical maintenance in agriculture. We have pointed out that in modern conditions it is impossible to forecast the automobiles maintenance operation frequency and as a result its improvement as well. It is obvious that one cannot achieve the considerable increase of maintenance operation efficiency by separate means and there exist the necessity to treat it as a system and use the up-to-date methods to investigate and improve complicated systems. We have made a conclusion that the increase of maintenance operation efficiency is not possible without some rational strategy of maintenance operation and repair. We have shown that the program of maintenance operation and repair being an integral part of automobiles technical maintenance has considerable effect on maintenance and repair quality. As a result, there is some necessity of the developed system of parameters diagnosing and control in technical maintenance and repair. We have shown that to get sufficient diagnose information one needs selection of the controlled parameters which give maximum information about the object technical status taking into account possible characteristics of its operational faults. We have discovered that in order to solve the task it is necessary to have the object’s information pattern, calculation of possible characteristics of the controlled object being in good or bad order due to some parts fault, evaluation of information brought by every parameter and determining parameters to be diagnosed. We have proposed to evaluate the parameters’ information value with the help of information entropy as uncertainty measure that is one of the main concepts of the information theory. Because of solving the task, we have got the aggregate of the controlled automobile parameters orderable according to the amount of information

    Full Text Available Abstract Background It is well known that most suicide cases meet criteria for a psychiatric disorder. However, rates of specific disorders vary considerably between studies and little information is known about gender and geographic differences. This study provides overall rates of total and specific psychiatric disorders in suicide completers and presents evidence supporting gender and geographic differences in their relative proportion. Methods We carried out a review of studies in which psychological autopsy studies of suicide completers were performed. Studies were identified by means of MEDLINE database searches and by scanning the reference list of relevant publications. Twenty-three variables were defined, 16 of which evaluating psychiatric disorders. Mantel-Haenszel Weighted Odds Ratios were estimated for these 16 outcome variables. Results Twenty-seven studies comprising 3275 suicides were included, of which, 87.3% (SD 10.0% had been diagnosed with a mental disorder prior to their death. There were major gender differences. Diagnoses of substance-related problems (OR = 3.58; 95% CI: 2.78–4.61, personality disorders (OR = 2.01; 95% CI: 1.38–2.95 and childhood disorders (OR = 4.95; 95% CI: 2.69–9.31 were more common among male suicides, whereas affective disorders (OR = 0.66; 95% CI: 0.53–0.83, including depressive disorders (OR = 0.53; 95% CI: 0.42–0.68 were less common among males. Geographical differences are also likely to be present in the relative proportion of psychiatric diagnoses among suicides. Conclusions Although psychopathology clearly mediates suicide risk, gender and geographical differences seem to exist in the relative proportion of the specific psychiatric disorders found among suicide completers.

    Full Text Available Introduction: The CHARGE association (coloboma of the eyes; heart disease; atresia of the choanae; retarded growth and development; genital hypoplasia/genitourinary anomalies; ear anomalies and/or hearing loss was first described in 1979 by Hall, and among its main features is hearing loss. This study presents a case aiming to establish relationships between performance on Infant Toddler Meaningful Auditory Integration Scale (IT-MAIS and Meaningful Use of Speech Scales (MUSS tests and the analysis of hearing and language categories of a patient diagnosed with CHARGE syndrome, before and after cochlear implant (CI surgery. Case Report: A 7-year-old girl was diagnosed with CHARGE. She had severe sensorineural hearing loss and was a prelingual unilateral CI user. We analyzed data from the patient's medical records regarding therapies and video recordings. Results: The patient showed positive results in all evaluations after CI. IT-MAIS rose from 5 to 90% following the use of CI. MUSS also rose, from 75 to 72.5%, after use of CI. Classification of Auditory Skills changed from category 1 before use of CI to category 6 after use of CI. Classification of Language Skills changed from category 1 before use of CI to category 3 after use of CI. The CI is an aid but there are many factors in the therapeutic process, and great heterogeneity in individuals diagnosed with CHARGE should be investigated. Conclusion: The development of listening and language skills after CI use was demonstrated by IT-MAIS and MUSS tests, and categorization of speech and hearing in this child with a diagnosis of CHARGE syndrome shows that CI can be an effective technological resource to provide information on hearing as one source for language construction.

  8. Brewer-Dobson circulation diagnosed from JRA-55

    We examine the Brewer-Dobson circulation (BDC) in the lower stratosphere diagnosed from the Japanese 55 year Reanalysis (JRA-55) data set and compare it with the BDCs diagnosed from the other reanalyses (i.e., ERA-Interim and JRA-25), and JRA-55-related data sets (i.e., JRA-55C, created by assimilating only in situ observations, and JRA-55AMIP, a simulation by a prediction model). The climatological mean seasonal change of the BDC in JRA-55 is similar to that in ERA-Interim but considerably different from that in JRA-25. Dynamical and thermodynamical consistencies among the variables are greatly improved in the JRA-55 data set. The interannual variations of the annual mean tropical upwellings in JRA-55 are almost coincident with those in JRA-55C. It suggests that the weakly increasing trend of the BDC found in JRA-55 does not have anything to do with changes in the satellite observing system. The climatological mean tropical upwelling diagnosed from JRA-55 is stronger than that from JRA-55AMIP. This difference is presumed to partly link to the model's inability to simulate the quasi-biennial oscillation (QBO). The JRA-55AMIP data set, a simple simulation performed without data assimilation, does not simulate the QBO, whereas the JRA-55 data set represents the QBO with the aid of data assimilation. The climatological mean zonal mean states of JRA-55AMIP considerably deviate from those of JRA-55 in the lower stratosphere. The deviation of JRA-55AMIP is similar to the modulation pattern by the QBO in specific phase regions in which the BDC is rather weak. The simulated QBO might enhance the BDC and reduce the model biases in the tropical lower stratosphere.

    Invasive aspergillosis (IA) remains a leading cause of mortality in immunocompromised patients, in part due to the difficulty of diagnosing this infection. Using thermal desorption-gas chromatography/mass spectrometry, we characterized the in vitro volatile metabolite profile of Aspergillus fumigatus, the most common cause of IA, and other pathogenic aspergilli. We prospectively collected breath samples from patients with suspected invasive fungal pneumonia from 2011 to 2013, and assessed whether we could discriminate patients with proven or probable IA from patients without aspergillosis, as determined by European Organization for Research and Treatment of Cancer/Mycoses Study Group consensus definitions, by direct detection of fungal volatile metabolites in these breath samples. The monoterpenes camphene, α- and β-pinene, and limonene, and the sesquiterpene compounds α- and β-trans-bergamotene were distinctive volatile metabolites of A. fumigatus in vitro, distinguishing it from other pathogenic aspergilli. Of 64 patients with suspected invasive fungal pneumonia based on host risk factors, clinical symptoms, and radiologic findings, 34 were diagnosed with IA, whereas 30 were ultimately diagnosed with other causes of pneumonia, including other invasive mycoses. Detection of α-trans-bergamotene, β-trans-bergamotene, a β-vatirenene-like sesquiterpene, or trans-geranylacetone identified IA patients with 94% sensitivity (95% confidence interval [CI], 81%-98%) and 93% specificity (95% CI, 79%-98%). In patients with suspected fungal pneumonia, an Aspergillus secondary metabolite signature in breath can identify individuals with IA. These results provide proof-of-concept that direct detection of exogenous fungal metabolites in breath can be used as a novel, noninvasive, pathogen-specific approach to identifying the precise microbial cause of pneumonia. © The Author 2014.

    2015-08-01

    Both covert hepatic encephalopathy (CHE) and overt hepatic encephalopathy (OHE) impair the ability to operate machinery. The legal responsibilities of US physicians who diagnose and treat patients with hepatic encephalopathy vary among states. It is imperative that physicians know the laws regarding reporting in their state. OHE represents a neuropsychiatric impairment that meets general reporting criteria. The medical advisory boards of the states have not identified OHE as a reportable condition. In the absence of validated diagnostic guidelines, physicians are not obligated to perform tests for CHE. There is a need for explicit guidance from professional associations regarding this issue.

    The therapeutic working alliance is a vital ingredient of psychotherapy, specifically for clients diagnosed with anorexia nervosa, as progress is often slow and treatment difficult. This qualitative phenomenological study investigated the experiences of eight clients with anorexia nervosa and seven therapists who work with this population, regarding which therapist factors aided in and challenged the working alliance formation in individual psychotherapy. Data was gathered through semi-structured interviews. Some helpful therapist factors included collaboration, appropriate self-disclosure, providing a warm and safe environment, and willingness to be contacted outside of a session. Unhelpful factors included lack of attunement and objectivity and failure to individualize treatment.

    Since Noecker first reported a colouterine fistula secondary to diverticulitis in 1929, about 20 cases have been reported in the literature. Methods for diagnosis have yet to be established. Herein we report the first case of a colouterine fistula at the level of the isthmus diagnosed at hysteroscopy. Diagnostic hysteroscopy enabled rapid diagnosis of the colouterine fistula. Diagnostic hysteroscopy is the first-choice diagnostic tool for investigation of any abnormal vaginal discharge such as blood or stool because it enables direct vision and biopsy of the lesions of the lower genital tract quickly and at low cost.

    Full Text Available Extramedullary plasmacytoma of tonsil is rare. Even though biopsy is necessary for final diagnosis, fine-needle aspiration cytology (FNAC can provide useful information in the management of such cases. We report a case of plasmacytoma of tonsil diagnosed by FNAC in a 43-year-old man who presented with a swelling in the right tonsillar area. FNAC smears revealed sheets of plasma cells at various stages of maturation. Subsequent histopathological and immunohistochemical studies confirmed the diagnosis of plasmacytoma. This case is reported for the rarity of site for extramedullary plasmacytoma and to highlight the usefulness of FNAC in lesions of tonsil.

    The vast number and variety of erosion lesions encountered today require reconsideration of the traditional definition. Dental erosion associated with modern dietary habits can exhibit unique features that symbolize a departure from the decades-old conventional image known as tooth surface loss. The extent and diversity of contemporary erosion lesions often cause conflicting diagnoses. Specific examples of these features are presented in this article. The etiologies, genesis, course of development, and characteristics of these erosion lesions are discussed. Contemporary and conventional erosion lesions are distinguished from similar defects, such as mechanically induced wear, carious lesions, and dental fluorosis, which affect the human dentition.

    Inhalation of asbestos fibres leads to asbestosis of the pleura and the lung, with possible progression to lung cancer and malignant pleural or peritoneal mesothelioma. Asbestosis remains difficult to diagnose, especially in its early stages. The most important role in its diagnosis is that of chest radiographs. The aim of this cross-sectional study was to address interobserver variations in interpreting chest radiographs in asbestos workers, which remain to be an issue, despite improvements in the International Labour Office (ILO) classification system. In our ten-year study, we investigated 318 workers occupationally exposed to asbestos, and in 210 workers with diagnosed asbestos-related changes we compared interpretations of chest radiographs according to ILO by two independent radiologists. The apparent degree of interobserver variation in classifying lung fibrosis was 26.66% for the diameter of changes and 42.2% for the profusion of the changes. In cases with diffuse pleural thickening, the interobserver variation using ILO procedures was 34.93%. This investigation raises the issue of standardisation and objectivity of interpretation of asbestosis according to the ILO classification system. This study has revealed a significant disagreement in the estimated degree of pleural and parenchymal asbestos pulmonary disease. This is why we believe high-resolution computed tomography (HRCT) should also be used as a part of international classification.

    Ataxia telangiectasia (A-T) is a common inherited cause of early childhood-onset ataxia, distinguished by progressive cerebellum malfunction, capillary vessel extension, and immunodeficiency. The diagnosis of A-T is sometimes difficult to establish in patients with atypical clinical evolution. We experienced a pediatric 12-years-old female patient, who was finally diagnosed with classic A-T, demonstrating progressive dystonic-myoclonic axial jerks with ataxia as a predominant clinical feature. Oculocutaneous telangiectasias and immune status were unremarkable. Her myoclonic jerks were spontaneous or stimulus-sensitive, and partially ameliorated by levodopa treatment, but the ataxia was slowly progressive. A laboratory examination showed moderate atrophy of the vermis and cerebellum on brain magnetic resonance imaging, elevated serum alpha fetoprotein (AFP) levels, and total absence of A-T mutated (ATM) protein activity. We subsequently confirmed compound heterozygous truncating mutations of the ATM gene in this patient. Our findings highlight the importance of recognizing dystonic-myoclonic jerks as one of the extrapyramidal signs of classic A-T. Measurement of AFP levels should be considered in patients with unexplained myoclonic jerk movements with ataxia in whom definitive diagnoses are not identified. Physicians should be aware that there are cases where typical findings of A-T may not be fulfilled. Copyright © 2014 The Japanese Society of Child Neurology. Published by Elsevier B.V.

    2013-01-01

    Flexible bronchoscopy with exfoliative cytology is an important tool for the diagnosis of pulmonary fungal infections. The question of colonization versus true fungal infection is of critical importance. A 5-year retrospective analysis of all cases of pulmonary fungal infection diagnosed using exfoliative cytology was performed. Clinical, radiological, bronchoscopy and histopathology findings were recorded. A total of 69 cases of mycoses were retrieved. The most common fungal organism identified was Aspergillus followed by Candida and Pneumocystis. Most cases of Aspergillus and Candida in cytological specimens presented as a pulmonary mass or endobronchial growth and were diagnosed as carcinomas in biopsy specimens, thus representing colonization. All cases of Pneumocystis with bilateral ground glass infiltrates and cryptococcosis with parenchymal mass lesion in radiology represented true infection. Histoplasma was identified in pleural fluid from a known case of lung carcinoma. Aspergillus and Candida species are the most common fungal organisms. Most of these represent colonization of malignant growths. However, true fungal infections may also present as mass lesions and may masquerade malignancy clinically. Fluid cytological examination is an important diagnostic modality for pulmonary mycoses; however, it is important to correlate results with clinical, bronchoscopy and biopsy findings for accurate diagnosis and appropriate management.

  8. Nonalcoholic fatty liver disease: Noninvasive methods of diagnosing hepatic steatosis

    2015-01-01

    Full Text Available Hepatic steatosis is the buildup of lipids within hepatocytes. It is the simplest stage in nonalcoholic fatty liver disease (NAFLD. It occurs in approximately 30% of the general population and as much as 90% of the obese population in the United States. It may progress to nonalcoholic steatohepatitis, which is a state of hepatocellular inflammation and damage in response to the accumulated fat. Liver biopsy remains the gold standard tool to diagnose and stage NAFLD. However, it comes with the risk of complications ranging from simple pain to life-threatening bleeding. It is also associated with sampling error. For these reasons, a variety of noninvasive radiological markers, including ultrasound, computed tomography, magnetic resonance spectroscopy, and the controlled attenuation parameter using transient elastography and Xenon-133 scan have been proposed to increase our ability to diagnose NAFLD, hence avoiding liver biopsy. The aim of this review is to discuss the utility and accuracy of using available noninvasive diagnostic modalities for fatty liver in NAFLD.

    A total of 30 patients suffering from brucellosis were suspected based on history taking, clinical manifestations and positive serum tube agglutination test (at titer > or = 1/160). The followings were done for all cases; complete blood picture (differential leucocytic count) and liver function tests, serodiagnosis of Brucella (serum tube agglutination test (STAT) as well as Rose Bengal test (RBT) and PCR. The study aimed to analyze the diagnostic value of RBT as compared to STAT and PCR for human brucellosis, and to evaluate the sensitivity, specificity, accuracy, the cost and the time consuming of RBT as compared to STAT and PCR. There was a significant difference between diagnosis by RBT and both STAT > or = 1/640, & STAT > or = 1/1280. Also, there was a significant difference between PCR and both STAT > or = 1/640, and STAT > or = 1/1280. No significant difference was detected between RBT in diagnosing acute and chronic infection. STAT > or = 1/320 proved to be better than STAT at other titers and RBT in diagnosis of brucellosis. RBT proved to be suitable as screening test regarding time (faster) and cost. But, STAT > or = 1/320 from a practical and economic point of views proved to be the best one in diagnosing human brucellosis.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the clinical and epidemiological characteristics of pubalgia in patients from a Sports Medicine Center. METHODS: Data analysis from medical records of patients with athletic pubalgia attended to from January 2007 to January 2015. The diagnosis was made by an experienced hip surgeon, complemented with pelvic X-ray, abdominal wall ultrasound, and magnetic resonance imaging of the pelvis. RESULTS: Among 43 patients, 42 were men, with mean age of 33 years. As for sports, 25 (58.1% athletes were soccer players and 13 (30.2% were runners; 37.2% were professional athletes. Inguinal hernia was diagnosed in 20.9% of patients, showing the importance of its routine search in these patients. Treatment duration ranged from 1 to 12 months and 95.2% of the patients returned to sport. CONCLUSION: This study presented the epidemiological characteristics of patients diagnosed with athletic pubalgia attended to in a reference medical center and demonstrated the prevalence of this lesion in male patients, soccer players and runners. It also disclosed a high success rate of the nonoperative treatment, and high rate of return to sport after treatment.

    Full Text Available The aims of this study were to evaluate the utility of shear wave elastography (SWE using acoustic radiation force impulse (ARFI for diagnosing chronic autoimmune thyroiditis (CAT and to verify the effect of fibrotic thyroid tissue on shear wave velocity (SWV. The subjects were 229 patients with 253 normal thyroid lobes (controls and 150 CAT lobes. The SWV for CAT (2.47 ± 0.57 m/s was significantly higher than that for controls (1.59 ± 0.41 m/s (P<0.001. The area under the receiver operating characteristics (ROC curve for CAT was 0.899, and the SWV cut-off value was 1.96 m/s. The sensitivity, specificity, and diagnostic accuracy were 87.4%, 78.7%, and 85.1%, respectively. Levels of anti-thyroperoxidase antibodies and thyroid isthmus thickness were correlated with tissue stiffness in CAT. However, there was no correlation between levels of anti-thyroglobulin antibodies and tissue stiffness. Quantitative SWE is useful for diagnosing CAT, and it is possible that SWE can be used to evaluate the degree of fibrosis in patients with CAT.

    To describe our experience with MR and angiography in diagnosing intracranial vasculitis and to test the hypothesis that MR can be used to screen for patients unlikely to have vasculitis. Ninety-two patients who had angiography with [open quotes]exclude vasculitis[close quotes] as the indication or who had angiography and a clinical diagnosis of vasculitis were identified. Angiograms of all 92 patients and the MRs of the 70 patients who had both studies were reviewed. Eleven patients had intracranial vasculitis. Angiography showed characteristic changes in 8. MR performed in 9 of 11 vasculitis cases, was significantly abnormal in all 9. Among 70 patients who had both studies, 19 had MR that was completely normal or showed only incidental findings. None of these 19 was diagnosed with vasculitis. The diagnostic yield of angiography performed to exclude vasculitis was only 6%. Evaluation for intracranial vasculitis should include MR. A negative MR excludes intracranial vasculitis more definitively than does a negative angiogram and makes the likelihood of finding vasculitis with angiography negligible. 23 refs., 5 figs., 4 tabs.

    Full Text Available Objective. To identify nursing diagnoses (ND formulated for elderly patients in a quaternary healthcare institution. Methodology. This was a descriptive cross-sectional study, conducted based on information contained in the records of 112 elderly patients, admitted from January to July 2011, in a public teaching hospital of Belo Horizonte, Minas Gerais (Brazil. Results. 53% of patients were female and were 70 years or older. The most common diseases that led to hospitalization were cardiac (31%, neoplasms (22%, lung (10% and vascular diseases (10%. Only 44% of the patients had a ND identified. After exclusion of repetitions, 36 different diagnosis labels were identified. The primary ND were: risk for infection (78%, impaired physical mobility (69%, risk for impaired skin integrity (59%, risk for falls (57%, imbalanced nutrition: less than body requirements (57%, risk for unstable blood glucose (51% and self-care deficit (51%. Conclusion. In this study, the ND were linked to human responses related to the causes of hospitalization. These diagnoses are the basis for planning nursing interventions and provide improved quality of life, independence and preservation of functionality for these people.

    Diagnosing narcolepsy without cataplexy is often a challenge as the symptoms are nonspecific, current diagnostic tests are limited, and there are no useful biomarkers. In this report, we review the clinical and physiological aspects of narcolepsy without cataplexy, the limitations of available diagnostic procedures, and the differential diagnoses, and we propose an approach for more accurate diagnosis of narcolepsy without cataplexy. A group of clinician-scientists experienced in narcolepsy reviewed the literature and convened to discuss current diagnostic tools, and to map out directions for research that should lead to a better understanding and more accurate diagnosis of narcolepsy without cataplexy. To aid in the identification of narcolepsy without cataplexy, we review key indicators of narcolepsy and present a diagnostic algorithm. A detailed clinical history is mainly helpful to rule out other possible causes of chronic sleepiness. The multiple sleep latency test remains the most important measure, and prior sleep deprivation, shift work, or circadian disorders should be excluded by actigraphy or sleep logs. A short REM sleep latency (≤ 15 minutes) on polysomnography can aid in the diagnosis of narcolepsy without cataplexy, although sensitivity is low. Finally, measurement of hypocretin levels can helpful, as levels are low to intermediate in 10% to 30% of narcolepsy without cataplexy patients.

    2016-04-01

    Nowadays most renal disorders, especially urinary tract malformations and renal cystic disease, are diagnosed antenatally. In cases of severe bilateral disease, intrauterine renal dysfunction may lead to renal oligohydramnios (ROH), resulting in pulmonary hypoplasia which affects perinatal mortality and morbidity as well as the long-term outcome. However, some infants may only have mild pulmonary and renal disease, and advances in postnatal and dialysis treatment have resulted in improved short- and long-term outcome even in those infants with severe ROH. Here, we review the current state of knowledge and clinical experience of patients presenting antenatally with severe bilateral renal disorders and ROH. By addressing underlying mechanisms, intrauterine tools of diagnosis and treatment as well as published outcome data, we hope to improve antenatal counselling and postnatal care. KEY SUMMARY POINTS: 1. Nowadays most renal disorders are diagnosed antenatally, especially urinary tract malformations and renal cystic disease. 2. Severe kidney dysfunction may lead to renal oligohydramnios, which can cause pulmonary hypoplasia and is a risk factor of perinatal mortality and postnatal renal outcome. However, as considerable clinical heterogeneity is present, outcome predictions need to be treated with caution. 3. Advances in postnatal and dialysis treatment have resulted in improved short- and long-term outcomes even in infants with severe renal oligohydramnios. 4. A multidisciplinary approach with specialist input is required when counselling a family with an ROH-affected fetus as the decision-making process is very challenging.

    Hemolytic uremic syndrome (HUS) is characterized by the presence of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney failure. It is the leading cause of acute kidney failure in children under 3 years of age. A variable number of patients develop proteinuria, hypertension, and chronic renal failure. To evaluate the renal involvement in pediatric patients diagnosed with HUS using the microalbumin/creatinine ratio. Descriptive concurrent cohort study that analyzed the presence of microalbuminuria in patients diagnosed with HUS between January 2001 and March 2012, who evolved without hypertension and normal renal function (clearance greater than 90ml/min using Schwartz formula). Demographic factors (age, sex), clinical presentation at time of diagnosis, use of antibiotics prior to admission, and need for renal replacement therapy were evaluated. Of the 24 patients studied, 54% were male. The mean age at diagnosis was two years. Peritoneal dialysis was required in 45%, and 33% developed persistent microalbuminuria. Antiproteinuric treatment was introduce in 4 patients, with good response. The mean follow-up was 6 years (range 6 months to 11 years). The serum creatinine returned to normal in all patients during follow up. The percentage of persistent microalbuminuria found in patients with a previous diagnosis of HUS was similar in our group to that described in the literature. Antiproteinuric treatment could delay kidney damage, but further multicenter prospective studies are necessary. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Full Text Available Breast cancer is the most common cancer and the leading cause of morbidity and mortality among women’s age between 50 and 74 years across the worldwide. In this paper we’ve proposed a method to detect the suspicious lesions in mammograms, extracting their features and classify them as Normal or Abnormal and Benign or Malignant for diagnosing of breast cancer. This method consists of two major parts: The first one is detection of regions of interest (ROIs. The second one is diagnosing of detected ROIs. This method was tested by Mini Mammography Image Analysis Society (Mini-MIAS database. To check method’s performance, we’ve used FROC (Free-Receiver Operating Characteristics curve in the detection part and ROC (Receiver Operating Characteristics curve in the diagnosis part. Obtained results show that the performance of detection part has sensitivity of 94.27% at 0.67 false positive per image. The performance of diagnosis part has 94.29% accuracy, with 94.11% sensitivity, 94.44% specificity in the classification as normal or abnormal mammogram, and has achieved 94.4%accuracy, with 96.15% sensitivity and 94.54% specificity in the classification as Benign or Malignant mammogram.

    1988-01-01

    MOORE is a rule-based, prototype expert system that assists in diagnosing operational Tracking and Data Relay Satellite (TDRS) problems. It is intended to assist spacecraft engineers at the TDRS ground terminal in trouble shooting problems that are not readily solved with routine procedures, and without expert counsel. An additional goal of the prototype system is to develop in-house expert system and knowledge engineering skills. The prototype system diagnoses antenna pointing and earth pointing problems that may occur within the TDRS Attitude Control System (ACS). Plans include expansion to fault isolation of problems in the most critical subsystems of the TDRS spacecraft. Long term benefits are anticipated with use of an expert system during future TDRS programs with increased mission support time, reduced problem solving time, and retained expert knowledge and experience. Phase 2 of the project is intended to provide NASA the necessary expertise and capability to define requirements, evaluate proposals, and monitor the development progress of a highly competent expert system for NASA's Tracking Data Relay Satellite. Phase 2 also envisions addressing two unexplored applications for expert systems, spacecraft integration and tests (I and T) and support to launch activities. The concept, goals, domain, tools, knowledge acquisition, developmental approach, and design of the expert system. It will explain how NASA obtained the knowledge and capability to develop the system in-house without assistance from outside consultants. Future plans will also be presented.

  19. Limits of the lab: diagnosing "latent gonorrhea," 1872-1910.

    Science.gov (United States)

    Bowen, Elliott

    2013-01-01

    One of the most heatedly contested disease entities in turn-of-the-century medicine was "latent gonorrhea," a condition first discussed in an 1872 paper published by the German-born gynecologist Emil Noeggerath. Although none of the bacteriological discoveries of the next few decades-including the isolation of the gonococcus in 1879-provided much evidence of its existence, by the 1890s most Western physicians and medical scientists had nonetheless come to believe that latent gonorrhea was a real, diagnosable disease. While in the wake of its resolution, leading gynecologists contended that laboratory science had cleared up the controversy over latent gonorrhea, in reality it was through more "traditional" diagnostic methods (especially the taking of case histories) that Noeggerath's once-debatable theory gained acceptance. As such, this episode challenges the idea that turn-of-the-century Western medicine witnessed a "laboratory revolution," and that with the rise of bacteriology "the clinic" no longer informed the processes by which doctors defined and diagnosed disease.

    Full Text Available Little research has been done on the validity of posttraumatic stress disorder (PTSD diagnoses that are found in Department of Veterans Affairs (VA administrative data, even though they are often used in VA research. We compared PTSD diagnoses found in VA administrative data with PTSD Checklist (PCL scores self-reported by 4,777 newly diagnosed participants in a national postal survey study. Using PCL scores of at least 50 as the gold standard, we compared positive predictive values (PPVs for at least one versus at least two PTSD diagnoses (found within 4 months of the first in VA administrative data overall and by subgroups of interest: age, sex, and clinic where first diagnosed. The overall PPV was 75% for at least one PTSD diagnosis and 82% for at least two PTSD diagnoses. Similarly, the PPV significantly increased for all subgroup analyses when at least two PTSD diagnoses were used. The increase in PPV was greatest for those first diagnosed in primary care and for those older than 65. To select a sample of veterans with more definitive PTSD from administrative data, researchers should select those veterans with at least two PTSD diagnoses as opposed to at least one.

  1. Confounding factors in diagnosing brain death: a case report

    2002-06-01

    Full Text Available Abstract Background Brain death is strictly defined medically and legally. This diagnosis depends on three cardinal neurological features: coma, absent brainstem reflexes, and apnea. The diagnosis can only be made, however, in the absence of intoxication, hypothermia, or certain medical illnesses. Case presentation A patient with severe hypoxic-ischemic brain injury met the three cardinal neurological features of brain death but concurrent profound hypothyroidism precluded the diagnosis. Our clinical and ethical decisions were further challenged by another facet of this complex case. Although her brain damage indicated a hopeless prognosis, we could not discontinue care based on futility because the only known surrogate was mentally retarded and unable to participate in medical planning. Conclusion The presence of certain medical conditions prohibits a diagnosis of brain death, which is a medicolegal diagnosis of death, not a prediction or forecast of future outcome. While prognostication is important in deciding to withdraw care, it is not a component in diagnosing brain death.

    The common treatments of melancholia are psychotherapy and taking medicines. The psychotherapy treatment which this study focuses on is limited by time and location. It is easier for psychiatrists to grasp information from clinical manifestation but it is difficult for psychiatrists to collect information from patients' daily conversations or emotion. To design a system which psychiatrists enable to capture patients' daily symptoms will show great help in the treatment. This study proposes to use fuzzy data mining algorithm to find association rules among keywords segmented from patients' daily voice/text messages to assist psychiatrists extract useful information before outpatient service. Patients of melancholia can use devices such as mobile phones or computers to record their own emotion anytime and anywhere and then uploading the recorded files to the back-end server for further analysis. The analytical results can be used for psychiatrists to diagnose patients' degrees of melancholia. Experimental results will be given to verify the effectiveness of the proposed methodology.

    Clarke, Juanne; van Amerom, Gudrun

    2008-01-01

    This paper reports on a content analysis of blogs written by people with Asperger's syndrome (AS), as well as people who are parents and caretakers of people with AS. The paper documents that the views of the two groups, based on 30 blogs from each perspective, are frequently oppositional to one another. Whereas the parents and caretakers usually accept the medical definition of the situation and seek assistance and a cure for their children, the Aspies argue against this pathologizing and medicalizing perspective. Those diagnosed with AS say they are happy with who they are and that any suffering they may have undergone has been the result of society and not inherent in their condition. The paper concludes with a discussion of the theoretical, methodological, substantive, and practical implications of these findings.

    Full Text Available There is a perennial expert debate about the criteria to be included or excluded for the DSM diagnoses of substance use dependence. Yet analysts routinely report evidence for the unidimensionality of the resulting checklist. If in fact the checklist is unidimensional, the experts are wrong that the criteria are distinct, so either the experts are mistaken or the reported unidimensionality is spurious. I argue for the latter position, and suggest that the traditional reflexive measurement model is inappropriate for the DSM; a formative measurement model would be a more accurate characterization of the institutional process by which the checklist is created, and a network or causal model would be a more appropriate foundation for a scientifically grounded diagnostic system.

  7. Diagnosing the Course of Learning – Concept, Difficulties and Chances

    Full Text Available To diagnose the course of learning during a longer period of time as it is similarly practiced in curriculum-based measurement (CBM one has to use tests which always are equally difficult and every time measure the same competence. Until today it is not clear how to construct a greater number of tests of equal difficulty und validity. Moreover, it is not clear which test theory is suitable for such tests since classical test theory turns out to be problematic with respect to such tests. Finally, suitable tests should be sensitive even to minor changes of competence. In this article a solution is offered based upon criterion-referenced tests, item sampling and the binomial test model. Finally, a forthcoming computer-based test is described which will overcome most of the problems and which can be used to measure the course of learning of mathematics with children of elementary school.

    A grossly obese woman was wrongly diagnosed throughout her adult life of having lymphoedema. Her condition was subsequently confirmed as lipoedema, an entirely different condition, which is noted in medical text books but is seldom taught to medical students or to general practitioners. The condition is caused by abnormal deposition of adipose tissue in the extremities (usually the lower limbs) and almost exclusively affects women. It often starts at puberty or may occur after pregnancy. The exact aetiology is not yet understood but genetic and hormonal factors may be implicated. The problem is that misdiagnosis leads to inappropriate tests and improper treatment to the patient. When recognised it is often too late to do anything for the patient and they become highly dependent on social care. This case describes how the diagnosis can be confirmed through an ultrasound image and illustrates the need for early recognition to facilitate specialist care. PMID:23709549

    There is little experience with the effect of pregnancy on Parkinson disease because the number of women with Parkinson disease who are of childbearing age is small. We report four cases beginning during the postpartum period and discuss the potential contribution of different factors that may influence the occurrence of Parkinson disease in this time period. Four women aged 29-35 years developed arm tremor, shoulder pain, dizziness, or decreased dexterity of the hand in the first few days or months after childbirth. They were initially diagnosed with postpartum depression or psychogenic parkinsonism. Finally, dopamine transporter imaging confirmed the diagnosis of young-onset Parkinson disease. Early-onset Parkinson disease may present in postpartum women. In women with atypical motor symptoms in addition to depression, this diagnosis should be considered.

    2015-11-01

    Similar to all eczematous disorders, irritant and allergic contact dermatitis are primarily defined by their morphology. In addition, the diagnosis of this specific reaction pattern on the skin (and mucous membranes) also requires prior exposure (direct or indirect) to an allergen or irritant. While it is quite easy to give a textbook description of the typical features of eczema, its clinical manifestations in daily practice are diverse and frequently uncharacteristic. Contact reactions may present as lichenoid, lymphomatoid, granulomatous, pigmented, purpuric, and erythema multiforme-like lesions, thus lacking the typical eczematous appearance and broadening the spectrum of differential diagnoses to be considered. Moreover, a considerable number of agents, acting by mechanisms other than contact, may trigger adverse reactions mimicking the eczematic morphology and distribution pattern of contact dermatitis. Increasingly used in oncology, this is especially true for drugs such as kinase inhibitors. Knowledge of these associations is crucial for the adequate diagnostic and therapeutic care of patients with supposed or actual contact dermatitis.

    Ectopia cordis is a rare congenital malformation in which the heart is located partially or totally outside the thoracic cavity. The estimated prevalence of ectopia cordis is 5.5-7.9 per million births and it comprises 0.1% of congenital heart diseases. Ectopia cordis is associated with other congenital heart diseases and various tissue and organ disorders. Common cardiac anomalies associated with ectopia cordis include ventricular septal defect, atrial septal defect, pulmonary stenosis, right ventricular diverticulum, double right ventricular outflow tract and tetralogy of Fallot. Extracardiac anomalies associated with ectopia cordis reported in the literature include omphalocele, gastrochisis, cleft lip and palate, scollosis and central nervous system malformations. Here we report a newborn with ectopia cordis who was diagnosed prenatally.

    A novel approach to modeling and diagnosing the cardiovascular system is introduced. A model exhibits a subset of the dynamics of the cardiovascular behavior of an individual by using a recurrent artificial neural network. Potentially, a model will be incorporated into a cardiovascular diagnostic system. This approach is unique in that each cardiovascular model is developed from physiological measurements of an individual. Any differences between the modeled variables and the variables of an individual at a given time are used for diagnosis. This approach also exploits sensor fusion to optimize the utilization of biomedical sensors. The advantage of sensor fusion has been demonstrated in applications including control and diagnostics of mechanical and chemical processes.

    2015-10-01

    Full Text Available ABSTRACTFungal arthritis is a rare complication of arthroscopic surgeries, but its possibility should always be considered due its deleterious effects on any joint. Infection caused by the fungus Histoplasma capsulatum is the most common cause of respiratory tract infections by fungi, meanwhile histoplasmosis arthritis is more rare than all other fungal infections. However, their atypical forms of arthritis and the importance of early diagnosis and treatment cannot be over-emphasized. Herein we report a case of knee monoarthritis in an immunocompetent patient with histoplasmosis arthritis following an arthroscopic meniscetomy, diagnosed by synovial biopsy and culture performed during a second arthroscopic procedure. The joint was debrided in this second intervention and the patient received itraconazole initially and fluconazole latter on. The arthritis subsided after 10 months of treatment.

    Full Text Available Partial deletion of the long arm of chromosome 13 is a rare chromosomal aberration which is related to mental retardation, growth restriction and various congenital malformations. Central nervous system, cardiac, genitourinary, skeletal malformations and craniofacial dysmorphism can be observed. Prenatal diagnosis is possible by karyotyping and early genetic sonogram. Prenatal diagnosis can be difficult in cases that are not accompanied by major malformations but mental retardation and developmental delay in the forefront. In this report we aimed to present a case diagnosed 13-q syndrome prenatally as a result of karyotyping done due to multiple abnormal ultrasound findings in 14 weeks of pregnancy.

    Full Text Available Neonatal sepsis can be classified into two subtypes depending upon whether the onset of symptoms is before 72 hours of life (early-onset neonatal sepsis—EONS or later (late-onset neonatal sepsis—LONS. These definitions have contributed greatly to diagnosis and treatment by identifying which microorganisms are likely to be responsible for sepsis during these periods and the expected outcomes of infection. This paper focuses on the tools that microbiologist can offer to diagnose and eventually prevent neonatal sepsis. Here, we discuss the advantages and limitation of the blood culture, the actual gold standard for sepsis diagnosis. In addition, we examine the utility of molecular techniques in the diagnosis and management of neonatal sepsis.

    2016-01-01

    Very little is known about diagnosing specific language impairment (SLI) in children who are exposed daily to a dialect (community language) and a standard variety (school instruction). The research reported here examines the specificity and sensitivity of language tests used so far to evaluate language performance in the context of diglossia (Cyprus). Sixteen children with SLI aged 5-9 years and 22 age-matched typically developing children were examined on a range of language tests modified to include dialectal differences. Properties of each test were evaluated through logistic regression analysis in order to identify children with SLI. The analysis revealed that many of the tests used are sufficiently accurate concerning sensitivity and specificity levels. Furthermore, a combination of tests is proposed as a good tool for diagnostic purposes. Speech and language therapists as well as researchers can now rely on an accurate diagnostic procedure within a practice-based evidence framework.

    2015-03-01

    Based on a terahertz (THz) pipe-based near-field imaging system, we demonstrate the capability of THz imaging to diagnose freshly surgically excised human colonic tissues. Through THz near-field scanning the absorbance of the colonic tissues, the acquired images can clearly distinguish cancerous tissues from healthy tissues fast and automatically without pathological hematoxylin and eosin stain diagnosis. A statistical study on 58 specimens (20 healthy tissues and 38 tissues with tumor) from 31 patients (mean age: 59 years; range: 46 to 79 years) shows that the corresponding diagnostic sensitivity and specificity on colonic tissues are both 100%. Due to its capability to perform quantitative analysis, our study indicates the potential of the THz pipe-based near-field imaging for future automation on human tumor pathological examinations.

    2003-01-01

    Despite their widespread use, the terms "syndrome", "disease" and "diagnosis" are sometimes utilized improperly and ambiguously, compounding the complexities of medical knowledge representation. The definitions and illustrative examples provided here will be useful for developers of diagnostic expert systems. Description of the Problem Representing medical knowledge is a highly complex endeavor. The improper use of the terms "syndrome", "disease" and their relations to "diagnosis" is one of the difficulties with which medical informaticians must deal, especially when developing expert systems to support diagnoses. Although ubiquitous in medical and lay discourse, the term "disease" has no unambiguous, generally accepted definition. How-ever, most of those using this term allow themselves the comfortable delusion that everyone knows what it means. Only sparse and fragmented literature could be found regarding this issue.

    2010-12-01

    Full Text Available ABSTRACT Fibromyalgia is a clinical syndrome characterized by widespread musculoskeletal pain associated with areas of the body known as tender points which, when pressured gently, cause an exaggerated pain response. The most accepted physiopathological theory is that the pain in fibromyalgia results from an unbalance between the pain transmission stimulus mechanism and the pain inhibition one. The symptoms range from widespread musculoskeletal pain; disruptive sleep patterns; fatigue; short-lived generalized stiffness (generally in the morning; edema sensation and paresthesia. There is a constant association with other functional syndrome such as: depression, anxiety, migraine and irritable bowel syndrome. In 1990 The American College of Rheumatology developed a set of criteria to diagnose fibromyalgia and include it in scientific studies so as to help with the upcoming of a patient´s diagnosis and its follow up.

    An albumin biosensor based on a potentiometric measurement using Biofield-effect-transistor (BioFET) has been designed and fabricated, and its characteristics were investigated. The BioFET was fabricated using semiconductor integrated circuit (IC) technology. The gate surface of the BioFET was chemically modified by newly developed self-assembled monolayer (SAM) synthesized by a thiazole benzo crown ether ethylamine (TBCEA)-thioctic acid to immobilize anti-albumin. SAM formation, antibody immobilization, and antigen-antibody interaction were verified using surface plasmon resonance (SPR). The output voltage changes of the BioFET with respect to various albumin concentrations were obtained. Quasi-reference electrode (QRE) and reference FET (ReFET) has been integrated with the BioFET, and its output characteristic was investigated. The results demonstrate the feasibility of the BioFET as the albumin sensor for diagnosing nephritis.

    Population pharmacokinetic (PopPK) modeling has become increasing important in drug development because it handles unbalanced design, sparse data and the study of individual variation. However, the increased complexity of the model makes it more of a challenge to diagnose the fit. Graphics can play an important and unique role in PopPK model diagnostics. The software described in this paper, PKgraph, provides a graphical user interface for PopPK model diagnosis. It also provides an integrated and comprehensive platform for the analysis of pharmacokinetic data including exploratory data analysis, goodness of model fit, model validation and model comparison. Results from a variety of modeling fitting software, including NONMEM, Monolix, SAS and R, can be used. PKgraph is programmed in R, and uses the R packages lattice, ggplot2 for static graphics, and rggobi for interactive graphics.

    PURPOSE: To validate the diagnosis of epilepsy in the Danish National Hospital Register. METHODS: We randomly selected 200 patients registered with epilepsy in the Danish National Hospital Register between 1977 and 2002 and validated the diagnosis according to the guidelines developed...... by the International League Against Epilepsy. RESULTS: We reviewed the medical records of 188 (94%) persons from 57 departments at 41 hospitals. The epilepsy diagnoses were confirmed in 153 patients, providing a positive predictive value for epilepsy of 81% (95% confidence interval (95% CI): 75-87%). Among the 35...... patients who did not fulfill the criteria for epilepsy, 14 were admitted after a single, unprovoked seizure. Among patients registered with epilepsy the positive predictive value of seizure disorder was 89% (95% CI: 83-93%). Among patients classified with epilepsy syndromes, the positive predictive value...

    2015-05-01

    Even though diagnosing and treating urinary tract infections (UTIs) in older people can be difficult, it is essential to prevent reduction in the patients' wellbeing. Near-patient testing can be useful, but guidelines on this discuss the use of urine dipstick testing and laboratory culture in some detail. In addition, there are significant differences in the management of males and females, those with recurrent infections, and those with catheters. Community nurses are well placed to assess and manage this common condition, implementing correct treatment and resolution, owing to the close relationships they cultivate with service users. This article discusses the diagnosis and management of UTIs in older people, highlighting the differentials and red flags that need to be addressed urgently.

    2016-08-01

    This article describes reasoning strategies used by clinicians in different diagnostic circumstances and how these modes of inquiry may allow further insight into the evaluation and treatment of patients. Specifically, it aims to make explicit the implicit logical considerations that guide a variety of strategies in the diagnostic process, as exemplified in specific clinical cases. It focuses, in particular, in strategies that clinicians use to move from a large set of possible diagnoses initially suggested by abductive inferences - the process of hypothesis generation that creates a diagnostic space - to a narrower set or even to a single 'best' diagnosis, where the criteria to determine what is 'best' may differ according to different strategies. Experienced clinicians should have a diversified kit of strategies - for example, Bayesian probability or inference to a lovely explanation - to select from among previously generated hypotheses, rather than rely on any one approach every time.

  11. The political control of medical diagnoses - welfare retrenchment through demedicalization

    interest or ‘need’. The paper compares two cases where retrenchment reforms have reframed medical conditions as personal preferences. First, access to fertility treatment has recently been cut off in the Danish health care system, because infertility is polit- ically reframed as putting their own interest......It is notoriously difficult to legitimize cutbacks in already existing welfare rights, but it somehow requires a redefinition of what falls within the limits of public responsibility. In Denmark, a universal welfare state, reforms have sought to regain political control over medical diagnoses...... a medical issue into a question about the citizen’s motivation and will- ingness to work. The paper traces the genealogy of these two clashes between medicine and universal welfare rights and how both childlessness and incapacity to work have been ‘demedicalized’ by the polit- ical system in order to smooth...

    Full Text Available We present a case of a 30-year-old mother of four who was incidentally diagnosed with cervical intraepithelial neoplasia (CIN III following surgical termination of pregnancy. Five years previously a routine smear test had shown mild dyskaryosis but was never repeated. She was referred to colposcopy and, underwent loop excision of the transformation zone (LLETZ and subsequently vaginal hysterectomy. Without this incidental finding she would have undoubtedly developed cervical cancer. We discuss the deficiencies in current cervical cancer prevention strategies and termination of pregnancy services. We emphasise the importance of ensuring that patients with dyskaryosis are not lost to follow-up and we consider whether there should be clearer guidance on the value of histological examination of products of conception following termination of pregnancy.

    2015-04-01

    To study whether employees who disclose a psychiatric diagnosis, such as depression risk stigmatisation and discrimination at the workplace. Randomised experimental study with 748 managers from German companies incorporating four case vignettes displaying an employee with different 'diagnoses' (depression, burnout, private crisis and thyroid dysfunction), but identical unspecific complaints. Main outcome measures were the managers' attitudes and their impact on stigmatisation with respect to job performance. In nearly all aspects of job performance, the diagnosis depression (psychiatric disorder) was seen as more critical than the diagnosis of a thyroid dysfunction (somatic disease). The diagnosis 'burnout' did not prove to be less stigmatising than 'depression'. Likewise 'private crisis' was rated less favourably than thyroid dysfunction. Therefore, employees have to evaluate if they disclose their psychiatric disorder or if they conceal it as a somatic illness.

    Full Text Available Ochoa syndrome, also known as urofacial syndrome, is a rare genetic disease (OMIM #236730 with autosomal recessive inheritance of mutations in the heparanase 2 (HPSE2 and the LRIG2 genes, characterized by functional obstructive uropathy and unusual facial abnormalities. Progression to renal failure if not early diagnosed is inevitable. The therapeutic goals are to restore bladder emptying, preventing damage to the urinary tract with the use of prophylactic antibiotics, clean intermittent catheterization, anticholinergic use, botulinum toxin injection, urinary diversion and bladder augmentation to slow the evolution of the disease. This article aims to report a patient with late diagnosis of Ochoa Syndrome, as well as describe its characteristics and clinical outcome.

    This study investigated the specific emotional lexicons in narratives created by persons diagnosed with antisocial personality disorder (ASPD) to test the hypothesis that individuals with ASPD exhibit deficiencies in emotional language. Study participants consisted of 60 prison inmates with ASPD, 40 prison inmates without ASPD, and 60 men without antisocial tendencies who described situations involving love, hate and anxiety depicted by photographs. The lexical choices made in the narratives were analyzed, and a comparison of the three groups revealed differences between the emotional narratives of inmates with ASPD, inmates without ASPD, and the control group. Although the narratives of the individuals with ASPD included more words describing emotions and higher levels of emotional intensity, the valence of these words was inappropriate. The linguistic characteristics of these narratives were associated with high levels of psychopathy and low emotional reactivity.

    Full Text Available Molecular signatures in Glioblastoma (GBM have been described that correlate with clinical outcome and response to therapy. The Proneural (PN and Mesenchymal (MES signatures have been identified most consistently, but others including Classical (CLAS have also been reported. The molecular signatures have been detected by array techniques at RNA and DNA level, but these methods are costly and cannot take into account individual contributions of different cells within a tumor. Therefore, the aim of this study was to investigate whether subclasses of newly diagnosed GBMs could be assessed and assigned by application of standard pathology laboratory procedures. 123 newly diagnosed GBMs were analyzed for the tumor cell expression of 23 pre-identified proteins and EGFR amplification, together allowing for the subclassification of 65% of the tumors. Immunohistochemistry (IHC-based profiling was found to be analogous to transcription-based profiling using a 9-gene transcriptional signature for PN and MES subclasses. Based on these data a novel, minimal IHC-based scheme for subclass assignment for GBMs is proposed. Positive staining for IDH1R132H can be used for PN subclass assignment, high EGFR expression for the CLAS subtype and a combined high expression of PTEN, VIM and/or YKL40 for the MES subclass. The application of the proposed scheme was evaluated in an independent tumor set, which resulted in similar subclass assignment rates as those observed in the training set. The IHC-based subclassification scheme proposed in this study therefore could provide very useful in future studies for stratification of individual patient samples.

    Full Text Available Background: A recent phase 1/2 clinical trial argued for caution for the use of sulfasalazine in progressive glioblastoma (GBM. However, the study enrolled patients with recurrent or progressive high-grade glioma indicating that patients recruited probably had severe disease. Thus, the study may not accurately reflect the effectiveness of sulfasalazine for GBM and we hypothesized that earlier sulfasalazine administration may lead to anticancer effects. Aim: The aim of this study was to investigate whether sulfasalazine can improve the outcomes of patients with newly diagnosed GBM. Subjects and Methods: A total of 12 patients were treated with temozolomide and sulfasalazine with radiation therapy after surgery. Twelve patients with primary GBM treated with temozolomide and radiation therapy formed the control group. Progression-free survival (PFS, overall survival (OS and seizure-free survival (SFS curves were obtained using the Kaplan-Meier method. The survival curves were compared using the log-rank test. Results: The median OS, PFS and SFS did not differ between the groups. Grade 3 or 4 adverse events occurred over the duration of the study in nine (75% patients. The median SFS was 12 months in nine patients who received sulfasalazine administration for more than 21 days, which was strongly but not significantly longer than the 3 months observed in the control group (P = 0.078. Conclusions: Sulfasalazine treatment with temozolomide plus radiotherapy for newly diagnosed primary GBM is associated with a high rate of discontinuation due to hematologic toxic effects. This treatment may have no effect on OS or PFS, although it may improve seizure control if an adequate dose can be administered.

  7. From inverse problems in mathematical physiology to quantitative differential diagnoses.

    Full Text Available The improved capacity to acquire quantitative data in a clinical setting has generally failed to improve outcomes in acutely ill patients, suggesting a need for advances in computer-supported data interpretation and decision making. In particular, the application of mathematical models of experimentally elucidated physiological mechanisms could augment the interpretation of quantitative, patient-specific information and help to better target therapy. Yet, such models are typically complex and nonlinear, a reality that often precludes the identification of unique parameters and states of the model that best represent available data. Hypothesizing that this non-uniqueness can convey useful information, we implemented a simplified simulation of a common differential diagnostic process (hypotension in an acute care setting, using a combination of a mathematical model of the cardiovascular system, a stochastic measurement model, and Bayesian inference techniques to quantify parameter and state uncertainty. The output of this procedure is a probability density function on the space of model parameters and initial conditions for a particular patient, based on prior population information together with patient-specific clinical observations. We show that multimodal posterior probability density functions arise naturally, even when unimodal and uninformative priors are used. The peaks of these densities correspond to clinically relevant differential diagnoses and can, in the simplified simulation setting, be constrained to a single diagnosis by assimilating additional observations from dynamical interventions (e.g., fluid challenge. We conclude that the ill-posedness of the inverse problem in quantitative physiology is not merely a technical obstacle, but rather reflects clinical reality and, when addressed adequately in the solution process, provides a novel link between mathematically described physiological knowledge and the clinical concept of

    Candidiasis is defined as an infection or disease caused by a fungus of the genus Candida. Rate of disseminated candidiasis increases with the growth of the number of immunocompromised patients. In the the last few decades the incidence of disseminated candidiasis is in growth as well as the mortality rate. The aim of this survey is to show the importance of serological tests implementation in disseminated candidiasis diagnose. This is a prospective study involving 60 patients with malign diseases with and without clinical signs of disseminated candidiasis and 30 healthy people who represent the control group. Apart from hemoculture, detection of circulating mannan antigen and adequate antibodies of Candida species applying comercial ELISA test was determined in each patient. This survey deals with relevant factors causing disseminated candidiasis. This survey showed that the group of patients with clinical signs of disseminated candidiasis had more patients with positive hemoculture to Candida species, then the group of patients without clinical signs of disseminated candidiasis. The number of patients being examined and positive to antigens and antibodies was higher (p candidiasis (7/30; 23.3%), then in the group of patients without clinical signs of disseminated candidiasis (0/30; 0%): Average value of titra antigen was statistically higher (p candidiasis 6/30 (20%) of patients had Candida spp.positive hemocultures while in the group of patients without clinical signs of disseminated candidiasis 1/30 (3.3%) of patients had Candida spp. positive hemocultures, which was considerably higher (p candidiasis were statistically significant, while correlation of results of hemoculture and antibodies was insignificant. Because of low sensitivity of hemoculture and time needed for isolation of Candida spp., introducing serological tests in regular procedures would speed disseminated candidiasis diagnose.

    Full Text Available Traumatic injuries to the vertebral column, spinal cord, and cauda equina nerve roots occur frequently in human and veterinary medicine and lead to devastating consequences. Complications include partial or complete loss of motor, sensory, and visceral functions, which are among the main causes of euthanasia in dogs. The present case report describes neurological functional recovery in two dogs that were treated surgically for severe spinal fracture and vertebral luxation. In the first case, a stray, mixed breed puppy was diagnosed with thoracolumbar syndrome and Schiff-Scherrington posture, as well as a T13 caudal epiphyseal fracture with 100% luxation between vertebrae T13 and L1; despite these injuries, the animal did show deep pain sensation in the pelvic limbs. Decompression through hemilaminectomy and spinal stabilization with vertebral body pins and bone cement were performed, and the treatment was supplemented with physiotherapy and acupuncture . In the second case, a mixed breed dog was diagnosed with a vertebral fracture and severe luxation between L6 and L7 after a vehicular trauma, but maintained nociception and perineal reflex. Surgical stabilization of the spine was performed using a modified dorsal segmental fixation technique Both patients showed significant recovery of neurological function. Complete luxation of the spinal canal observed radiographically does not mean a poor prognosis, and in some cases, motor, sensory, and visceral functions all have the potential for recovery. In the first case the determining factor for good prognosis was the presence of deep pain perception, and in the second case the prognosis was determined by the presence of sensitivity and anal sphincter tone during the initial neurological examination

    Full Text Available Lin Lin, Xiao-mei Chen, Rong-hua Liu Department of Obstetrics and Gynecology, Linyi People’s Hospital, Shandong, People’s Republic of China Background: Postpartum depression (PPD could affect ~10% of women and impair the quality of mother–infant interactions. Currently, there are no objective methods to diagnose PPD. Therefore, this study was conducted to identify potential biomarkers for diagnosing PPD.Materials and methods: Morning urine samples of PPD subjects, postpartum women without depression (PPWD and healthy controls (HCs were collected. The gas chromatography-mass spectroscopy (GC-MS-based urinary metabolomic approach was performed to characterize the urinary metabolic profiling. The orthogonal partial least-squares-discriminant analysis (OPLS-DA was used to identify the differential metabolites. The logistic regression analysis and Bayesian information criterion rule were further used to identify the potential biomarker panel. The receiver operating characteristic curve analysis was conducted to evaluate the diagnostic performance of the identified potential biomarker panel.Results: Totally, 73 PPD subjects, 73 PPWD and 74 HCs were included, and 68 metabolites were identified using GC-MS. The OPLS-DA model showed that there were 22 differential metabolites (14 upregulated and 8 downregulated responsible for separating PPD subjects from HCs and PPWD. Meanwhile, a panel of five potential biomarkers – formate, succinate, 1-methylhistidine, a-glucose and dimethylamine – was identified. This panel could effectively distinguish PPD subjects from HCs and PPWD with an area under the curve (AUC curve of 0.948 in the training set and 0.944 in the testing set.Conclusion: These results demonstrated that the potential biomarker panel could aid in the future development of an objective diagnostic method for PPD.

    Andrew J Schissler

    Full Text Available BACKGROUND: It is unknown whether the observed increase in computed tomography pulmonary angiography (CTPA utilization has resulted in increased detection of pulmonary emboli (PEs with a less severe disease spectrum. METHODS: Trends in utilization, diagnostic yield, and disease severity were evaluated for 4,048 consecutive initial CTPAs performed in adult patients in the emergency department of a large urban academic medical center between 1/1/2004 and 10/31/2009. Transthoracic echocardiography (TTE findings and peak serum troponin levels were evaluated to assess for the presence of PE-associated right ventricular (RV abnormalities (dysfunction or dilatation and myocardial injury, respectively. Statistical analyses were performed using multivariate logistic regression. RESULTS: 268 CTPAs (6.6% were positive for acute PE, and 3,780 (93.4% demonstrated either no PE or chronic PE. There was a significant increase in the likelihood of undergoing CTPA per year during the study period (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.04-1.07, P<0.01. There was no significant change in the likelihood of having a CTPA diagnostic of an acute PE per year (OR 1.03, 95% CI 0.95-1.11, P = 0.49. The likelihood of diagnosing a less severe PE on CTPA with no associated RV abnormalities or myocardial injury increased per year during the study period (OR 1.39, 95% CI 1.10-1.75, P = 0.01. CONCLUSIONS: CTPA utilization has risen with no corresponding change in diagnostic yield, resulting in an increase in PE detection. There is a concurrent rise in the likelihood of diagnosing a less clinically severe spectrum of PEs.

    Full Text Available Background Coronary heart disease (CHD is a major health concern, affecting nearly half the middle-age population and responsible for nearly one-third of all deaths. Clinicians have responsibilities beyond diagnosing CHD, including risk stratification of patients for major adverse cardiac events (MACE, modifying the risks and treating the patient. In this first of a two-part review, identifying risk factors is reviewed, including more potential benefit from autonomic testing. Methods Traditional and non-traditional, and modifiable and non-modifiable risk factors for MACE where compared, including newer risk factors, such as inflammation, carotid intimal thickening, ankle-brachial index, CT calcium scoring, and autonomic function testing, specifically independent measurement of parasympathetic and sympathetic (P&S activity. Results The Framingham Heart Study, and others, have identified traditional risk factors for the development of CHD. These factors effectively target high-risk patients, but a large number of individuals who will develop CHD and MACE are not identified. Many patients with CHD who appear to be well-managed by traditional therapies still experience MACE. In order to identify these patients, other possible risk factors have been explored. Advanced autonomic dysfunction, and its more severe form, cardiac autonomic neuropathy, have been strongly associated with an elevated risk of cardiac mortality and are diagnosable through P&S testing. Conclusions Independent measures of P&S activity, provides additional information and has the potential to incrementally add to risk assessment. This additional information enables physicians to (1 specifically target more high-risk patients and (2 titrate therapies, with autonomic testing guidance, in order to minimize risk of cardiac mortality and morbidity.

    2017-02-01

    Full Text Available BACKGROUND Acute appendicitis is one of the most common cause of acute abdominal pain and emergency appendicectomy is the most common emergency surgery. The diagnosis of appendicitis is confirmed by histopathological examination that is not possible before appendicectomy. The negative exploration remains high in the rate of about 15-30%. 1 Scoring systems based on history, clinical examination and basic investigations are there in aiding the diagnosis of acute appendicitis and decreasing negative exploration. This study compares RIPASA and ALVARADO scoring systems in diagnosing acute appendicitis. 2 MATERIALS AND METHODS A comparative study was done between November 2014 to June 2015. Patients diagnosed as acute appendicitis in Department of General Surgery, Government Royapettah Hospital. 100 of them are to be selected on the basis of nonprobability (purposive sampling method. After considering the inclusion and exclusion criteria, 96 were enrolled into the study. A full history, clinical examination and both scoring systems were done on the patients. RESULTS In 96 patients, 46 patients (48% were male and 50 patients (52% were female. 65 patients underwent emergency appendicectomy based on the clinical decision. The sensitivity and specificity of the RIPASA scoring system was 98.0% and 80.43%, respectively. The sensitivity and specificity of the ALVARADO scoring system was 80.43% and 86.95%, respectively. The PPV (positive predictive value of RIPASA and ALVARADO was 84% and 85%, respectively. The NPP (negative predictive value of RIPASA and ALVARADO was 97% and 71%, respectively. The diagnostic accuracy was 89% for RIPASA and 77% for ALVARADO. CONCLUSION The RIPASA scoring is better than ALVARADO scoring in the diagnosis of acute appendicitis.

    Aim: To evaluate the quantitative information ofN20, a main component of SEP, in the prognosis ofpatients with conscious disturbance after a year. Methods: N20 data and clinic cases histories of the patients with conscious disturbance caused by different factors form July 2005 to July 2009 were retrospectively reviewed. Different statistical methods such as t test, Mann-Whitney U test, X 2 test, ROC curves, Kaplan-Meier analysis were used to compare the parameters ofbilateral N20 between the awakened group and the unawakened group and to estimate the patients ' prognosis. Results: Bilateral N20 could be used to predict the prognosis of patients with conscious disturbance (the area under ROC curve of C3 ' -N20 latency occupied 77.6% and the area under ROC curve of C4 ' -N20 latency occupied 79.3%). The bilateral average N20 latencies of the patients still in conscious disturbance were statistically longer than the ones of the patients could have been awaken, however there was no statistical difference in bilateral N20 amplitudes between the two groups. The sensitivity and specificity were 70.8% and 75.0% separately at the point of C4 ' -N20 latency being 20.05 ms which was the best estimated and 75.0% and 72% separately at the point of C4 ' -N20 latency being 19.95 ms. The prognosis of the patients in conscious disturbance with C3' -N20 latency<19.95 ms and C4 ' -N20 latency<20.05 ms after one year were the best, with the smallest percentage of the patients still in conscious disturbance 1 year later and the shortest average time which they took to recover from conscious disturbance. Conclusion: The bilateral N20 latencies are considered as an accurate index to predict the prognoses ofpatients with conscious disturbance, when the patients with bilaterally N20 existent had the best outcomes. The point of C3 ' -N20 latency being 19.95 ms and the point of C4' -N20 latency being 20.05 ms were considered as the best boundaries that could separate the

    The threat for aircraft icing in clouds is a significant hazard that routinely impacts aviation operations. Accurate diagnoses and forecasts of aircraft icing conditions requires identifying the location and vertical distribution of clouds with super-cooled liquid water (SLW) droplets, as well as the characteristics of the droplet size distribution. Traditional forecasting methods rely on guidance from numerical models and conventional observations, neither of which currently resolve cloud properties adequately on the optimal scales needed for aviation. Satellite imagers provide measurements over large areas with high spatial resolution that can be interpreted to identify the locations and characteristics of clouds, including features associated with adverse weather and storms. This paper describes new techniques for interpreting cloud products derived from satellite data to infer the flight icing threat to aircraft. For unobscured low clouds, the icing threat is determined using empirical relationships developed from correlations between satellite imager retrievals of liquid water path and droplet size with icing conditions reported by pilots (PIREPS). For deep ice over water cloud systems, ice and liquid water content (IWC and LWC) profiles are derived by using the imager cloud properties to constrain climatological information on cloud vertical structure and water phase obtained apriori from radar and lidar observations, and from cloud model analyses. Retrievals of the SLW content embedded within overlapping clouds are mapped to the icing threat using guidance from an airfoil modeling study. Compared to PIREPS and ground-based icing remote sensing datasets, the satellite icing detection and intensity accuracies are approximately 90% and 70%, respectively, and found to be similar for both low level and deep ice over water cloud systems. The satellite-derived icing boundaries capture the reported altitudes over 90% of the time. Satellite analyses corresponding to

    Full Text Available In­tro­duc­ti­on: Inflammatory bowel disease (IBD is a chronic inflammatory disease of the gastrointestinal canal characterised by remissions and exacerbations. This study aimed to make a retrospective evaluation of clinical and laboratory findings of patients being monitored with a diagnosis of IBD.Materials and Methods: Medical records of 18 patients with a diagnosis of IBD and 7 years of follow-up at our pediatric gastroenterology departments were investigated with respect to demographic data, complaints on presentation and accompanying diseases. Unusual findings from physical examination, endoscopic findings, histopathological findings and the applied treatments were examined.Results: The 18 patients (10 female, 8 male included in this study had a mean age of 13.6±2.9 years and the mean time from onset of symptoms to diagnosis was 6.9±4.5 months. Seventeen patients were diagnosed with ulcerative colitis and 1 patient with intermediate colitis. There was a positive family history of the disease in 2 patients (11%. At the time of diagnosis, the most common complaints on presentation were found to be abdominal pain (100%, bloody diarrhea (94.5% and tenesmus (44.4%. The most frequent laboratory findings were CRP positivity (89%, increased sedimentation rate (83.3% and iron-deficient anaemia (77.7%. On colonoscopy, pancolitis involvement (66.6% was most frequently encountered. Accompanying diseases to IBD were found to be familial Mediterranean fever (FMF (11%, celiac disease (5.5% and Heliobacter pylori gastritis (5.5%. One patient (5.5% who did not respond to medical treatment for pancolitis involvement underwent a colectomy. Discussion: The number of diagnoses of IBD in childhood is gradually increasing. Nonetheless, it can be difficult to define diseases with non-specific symptoms and this may cause a delay in diagnosis. Because of the association of autoimmune diseases with IBD, despite appropriate therapy, diseases with no remission

    The impact of prolonging temozolomide (TMZ) maintenance beyond six cycles in newly diagnosed glioblastoma (GBM) remains a topic of discussion. We investigated the effects of prolonged TMZ maintenance on progression-free survival (PFS) and overall survival (OS). In this retrospective single-center cohort study, we included patients with GBM who were treated with radiation therapy with concomitant and adjuvant TMZ. For analysis, patients were considered who either completed six TMZ maintenance cycles (group B), continued with TMZ therapy beyond six cycles (group C), or stopped TMZ maintenance therapy within the first six cycles (group A). Patients with progression during the first six TMZ maintenance cycles were excluded. Clinical data from 107 patients were included for Kaplan-Meier analyses and 102 for Cox regressions. Median PFS times were 8.1 months (95% confidence interval [CI] 6.1-12.4) in group A, 13.7 months (95% CI 10.6-17.5) in group B, and 20.9 months (95% CI 15.2-43.5) in group C. At first progression, response rates of TMZ/lomustine rechallenge were 47% in group B and 13% in group C. Median OS times were 12.7 months (95% CI 10.3-16.8) in group A, 25.2 months (95% CI 17.7-55.5) in group B, and 28.6 months (95% CI 24.4-open) in group C. Nevertheless, multivariate Cox regression for patients in group C compared with group B that accounted for imbalances of other risk factors showed no different relative risk (RR) for OS (RR 0.77, p = .46). Our data do not support a general extension of TMZ maintenance therapy beyond six cycles. The Oncologist 2017;22:570-575 IMPLICATIONS FOR PRACTICE: Radiation therapy with concomitant and adjuvant temozolomide (TMZ) maintenance therapy is still the standard of care in patients below the age of 65 years in newly diagnosed glioblastoma. However, in clinical practice, many centers continue TMZ maintenance therapy beyond six cycles. The impact of this continuation is controversial and has not yet been addressed in

    Full Text Available Background: This observational study was aimed to determine the frequency of existence of sero-positivity for human immunodeficiency virus (HIV infection among women of age between 25 to 75 years with invasive cervical carcinoma and to decide whether HIV testing should be included as part of the initial routine work-up of cervical cancer patients. Methods: Histologically proven 120 cases of invasive carcinoma cervix, who came for treatment between 2009-2013, in the department of radiotherapy, after counselling gave consent were investigated for HIV by immunochromatography based rapid test. Results: Out of 120 patients investigated, reports revealed that only two patients (1.67% were HIV seropositive. Both of these patients were already HIV seropositive and on gynaecological screening were found to have malignancy of cervix. No patient of diagnosed carcinoma cervix was found seropositive for HIV. Most patients (106/120 were above 40 years of age, from rural background (92/120 and housewives (80/120. Only 15% (18/120 were smokers. 95.8% (115/120 were of stage II and III. None presented with metastasis. Most common pathology was moderately differentiated carcinoma, in 76 patients (63.3%. Conclusion: Screening for HIV, as part of the initial work up for cervical cancer is not necessary in countries with limited resources and low HIV prevalence.

    Chest auscultation is a crucial and efficient method for diagnosing lung disease; however, it is a subjective process that relies on physician experience and the ability to differentiate between various sound patterns. Because the physiological signals composed of heart sounds and pulmonary sounds (PSs) are greater than 120 Hz and the human ear is not sensitive to low frequencies, successfully making diagnostic classifications is difficult. To solve this problem, we constructed various PS recognition systems for classifying six PS classes: vesicular breath sounds, bronchial breath sounds, tracheal breath sounds, crackles, wheezes, and stridor sounds. First, we used a piezoelectric microphone and data acquisition card to acquire PS signals and perform signal preprocessing. A wavelet transform was used for feature extraction, and the PS signals were decomposed into frequency subbands. Using a statistical method, we extracted 17 features that were used as the input vectors of a neural network. We proposed a 2-stage classifier combined with a back-propagation (BP) neural network and learning vector quantization (LVQ) neural network, which improves classification accuracy by using a haploid neural network. The receiver operating characteristic (ROC) curve verifies the high performance level of the neural network. To expand traditional auscultation methods, we constructed various PS diagnostic systems that can correctly classify the six common PSs. The proposed device overcomes the lack of human sensitivity to low-frequency sounds and various PS waves, characteristic values, and a spectral analysis charts are provided to elucidate the design of the human-machine interface.

    To guide the clinician in taking decisions on the best strategies for assessing and monitoring the risk of blood disorders in adults diagnosed with schizophrenia in pharmacological treatment. A clinical practice guideline was developed following the guidelines of the Methodological Guide of the Ministry of Social Protection to collect evidence and grade recommendations. De novoliterature researchwas performed. With the use of antipsychotics there isriskofreducción in the leukocyte count and the risk of agranulocytosis,the later associated with the use of clozapine, although it is a rare event(0.8%) can be fatal; this effect occurs most frequently in the first twelve weeks of treatment and the risk is maintained aroundthe first year of it. The recommendations were considered strongin all hematologic related monitoring.A blood count should be taken at the start of pharmacological treatment. If the patient is started on clozapine one shouldbe taken weekly during the first three months, monthly until completing one year and every six months thereafter. If there is a decrease in white blood cell count the patient should be monitored regularly, stopping if is a less than 3,500 cells/mm(3) and consider referral if is less than 2,000 cells/mm(3).

    2015-01-01

    This study explored the impact of undersampling on the accuracy of tally estimates in Monte Carlo (MC) calculations. Steady-state MC simulations were performed for models of several critical systems with varying degrees of spatial and isotopic complexity, and the impact of undersampling on eigenvalue and fuel pin flux/fission estimates was examined. This study observed biases in MC eigenvalue estimates as large as several percent and biases in fuel pin flux/fission tally estimates that exceeded tens, and in some cases hundreds, of percent. This study also investigated five statistical metrics for predicting the occurrence of undersampling biases in MC simulations. Three of the metrics (the Heidelberger-Welch RHW, the Geweke Z-Score, and the Gelman-Rubin diagnostics) are commonly used for diagnosing the convergence of Markov chains, and two of the methods (the Contributing Particles per Generation and Tally Entropy) are new convergence metrics developed in the course of this study. These metrics were implemented in the KENO MC code within the SCALE code system and were evaluated for their reliability at predicting the onset and magnitude of undersampling biases in MC eigenvalue and flux tally estimates in two of the critical models. Of the five methods investigated, the Heidelberger-Welch RHW, the Gelman-Rubin diagnostics, and Tally Entropy produced test metrics that correlated strongly to the size of the observed undersampling biases, indicating their potential to effectively predict the size and prevalence of undersampling biases in MC simulations.

    Full Text Available Multiple myeloma, being a malignant proliferation of plasma cells in the bone marrow, has clinical spectrum varying from monoclonal gammopathy with unknown significance to plasma cell leukemia. The presenting symptoms have usually been bone pain, pathologic fractures or repeating infections. In patients with multiple myeloma, amyloid depositions may be seen in the skin. This form, defined as primary systemic amyloidosis, is characterized by light-chain amyloid fibril depositions. Our case applied with multiple, asymptomatic, yellowish papules localized on the face, trunk, oral and genital mucosa, gradually increasing during the last two years. He had no complaints, except for slight weight loss. In routine tests, the patient had no pathological laboratory findings, except high C-reactive protein levels. Further research revealed histopathologic and immunohistochemical findings consistent with amyloidosis. Upon these results, immunoglobulin G levels were measured and found high, and in protein electrophoresis, IgG monoclonal gammopathy was determined. The diagnosis of multiple myeloma is made by bone marrow biopsy. This patient is presented for being an asymptomatic case diagnosed by skin findings of amyloidosis.

  7. Use of Bayesian statistical approach in diagnosing secondary hypertension.

    Krzych, Lukasz Jerzy

    2008-03-01

    Bayes's theorem is predominantly used in diagnosing based on the results of various diagnostic tests. This statistical approach is intuitive in differential diagnosis as it explicitly takes into consideration data from medical history, physical examination, laboratory findings and imaging. Bayes's theorem states that the probability of disease occurrence (or occurrence of other outcome) after new information is obtained, called a posteriori probability, depends directly on an a priori probability and the value of likelihood ratio associated with a given test result. This paper describes basic Bayesian analysis in relation to the diagnosis of two types of secondary hypertension; primary aldosteronism and pheochromocytoma. This choice is based on two facts; primary aldosteronism is believed to be the most common and the most commonly detected cause of symptomatic hypertension and pheochromocytoma is thought to have rapid progress and stormy clinical course. This article aims to draw physicians' attention to and increase the knowledge of Bayesian analysis, and to describe its use in everyday clinical decision making. On the basis of this theorem's foundations, the discussion in relation to the issue of differential diagnosis between physicians, their patients, and medical students should also improve. When used in practice, one should be aware, however, of Bayesian analysis limitations concerning the diagnostic test application and limited knowledge of diagnostic test accuracy, and insecure or faulty a priori probability estimates.

    We present the first prospective test of Raman spectroscopy in diagnosing normal, benign, and malignant human breast tissues. Prospective testing of spectral diagnostic algorithms allows clinicians to accurately assess the diagnostic information contained in, and any bias of, the spectroscopic measurement. In previous work, we developed an accurate, internally validated algorithm for breast cancer diagnosis based on analysis of Raman spectra acquired from fresh-frozen in vitro tissue samples. We currently evaluate the performance of this algorithm prospectively on a large ex vivo clinical data set that closely mimics the in vivo environment. Spectroscopic data were collected from freshly excised surgical specimens, and 129 tissue sites from 21 patients were examined. Prospective application of the algorithm to the clinical data set resulted in a sensitivity of 83%, a specificity of 93%, a positive predictive value of 36%, and a negative predictive value of 99% for distinguishing cancerous from normal and benign tissues. The performance of the algorithm in different patient populations is discussed. Sources of bias in the in vitro calibration and ex vivo prospective data sets, including disease prevalence and disease spectrum, are examined and analytical methods for comparison provided.

    Abstract At present, we do not know the exact prevalence of Barrett esophagus (BE) developing later in patients without BE in their first endoscopic screening. The purpose of this study was to determine the prevalence of BE on the second endoscopic examination of patients who had no BE in their first endoscopic examination. The data of the patients older than 18 years who had undergone upper gastrointestinal system endoscopy more than once at the endoscopy unit of our clinic during the last 6 years were retrospectively analyzed. During the last 6 years, 44,936 patients had undergone at least one endoscopic examination. Among these patients, 2701 patients who had more than one endoscopic screening were included in the study. Of the patients, 1276 (47.3%) were females and 1425 (52.7%) were males, with an average age of 54.9 (18–94) years. BE was diagnosed in 18 (0.66%) of the patients who had no BE in the initial endoscopic examination. The patients with BE had reflux symptoms in their medical history and in both endoscopies, they revealed a higher prevalence of lower esophageal sphincter laxity, hiatal hernia, and reflux esophagitis when compared to patients without BE (P < 0.001). Our study showed that in patients receiving no diagnosis of BE on their first endoscopic examination performed for any reason, the prevalence of BE on their second endoscopy within 6 years was very low (0.66%).

    Full Text Available Objective. EEG has great potential as a cost-effective screening tool for Alzheimer's disease (AD. However, the specificity of EEG is not yet sufficient to be used in clinical practice. In an earlier study, we presented preliminary results suggesting improved specificity of EEG to early stages of Alzheimer's disease. The key to this improvement is a new method for extracting sparse oscillatory events from EEG signals in the time-frequency domain. Here we provide a more detailed analysis, demonstrating improved EEG specificity for clinical screening of MCI (mild cognitive impairment patients. Methods. EEG data was recorded of MCI patients and age-matched control subjects, in rest condition with eyes closed. EEG frequency bands of interest were θ (3.5–7.5 Hz, α1 (7.5–9.5 Hz, α2 (9.5–12.5 Hz, and β (12.5–25 Hz. The EEG signals were transformed in the time-frequency domain using complex Morlet wavelets; the resulting time-frequency maps are represented by sparse bump models. Results. Enhanced EEG power in the θ range is more easily detected through sparse bump modeling; this phenomenon explains the improved EEG specificity obtained in our previous studies. Conclusions. Sparse bump modeling yields informative features in EEG signal. These features increase the specificity of EEG for diagnosing AD.

    Asthma is a lung chronic inflammatory disorder estimated between 1.4% and 27.1% in different area of the world. Result of various studies show that asthma is usually underdiagnosed especially in developing countries, because of limitations on access to medical specialists and laboratory facilities. In this paper, we report on the development and evaluation of a novel patient-based fuzzy system that promotes the diagnosis method of asthma. The design of this application addresses five critical issues included: 1) modular representation of asthma diagnostic variables regard to patients' perception of the disease, 2) algorithmic approaches conducting inference of diagnosing based on patient's response to questions, 4) front-end mechanism for capturing data from patient, 5) output for both patient and physician regard to asthma possibility. for the system output score (0-10) the efficacy of this system calculated in the study sample included 139 asthmatic patients and 139 non-asthmatic patients (age range 6-18) reinforce the sensitivity of 88% and specificity of 100% for cut off value 0.7.

    Primary ciliary dyskinesia (PCD) is a rare genetic disorder characterised by progressive sino-pulmonary disease, with symptoms starting soon after birth. A European Respiratory Society (ERS) Task Force aims to address disparities in diagnostics across Europe by providing evidence-based clinical practice guidelines. We aimed to identify challenges faced by patients when referred for PCD diagnostic testing. A patient survey was developed by patient representatives and healthcare specialists to capture experience. Online versions of the survey were translated into nine languages and completed in 25 countries. Of the respondents (n=365), 74% were PCD-positive, 5% PCD-negative and 21% PCD-uncertain/inconclusive. We then interviewed 20 parents/patients. Transcripts were analysed thematically. 35% of respondents visited their doctor more than 40 times with PCD-related symptoms prior to diagnostic referral. Furthermore, the most prominent theme among interviewees was a lack of PCD awareness among medical practitioners and failure to take past history into account, leading to delayed diagnosis. Patients also highlighted the need for improved reporting of results and a solution to the “inconclusive” diagnostic status. These findings will be used to advise the ERS Task Force guidelines for diagnosing PCD, and should help stakeholders responsible for improving existing services and expanding provision for diagnosis of this rare disease.

    Full Text Available Objective: Oral tongue cancer presents clinical challenges to effective diagnosis that affect patient experience. Patient experience of the diagnostic process is poorly described, making opportunities for nursing intervention unclear. Methods: We qualitatively describe, using constant comparative analysis, oral tongue cancer diagnosis using data from a larger grounded theory study of oral tongue cancer survivorship. Using constant comparative analysis - in keeping with the methodology of the main study - we analyzed 16 survivor interviews for themes explaining the patient experience of oral tongue cancer diagnosis. Results: We termed the broader diagnostic process "living in limbo." This process includes the themes describing the peri-diagnostic process itself - "self-detected lesion," "lack of concern," "seeking help," "not a straightforward diagnosis," and "hearing the diagnosis." Entry into treatment concludes "Living in Limbo" and is described by the theme "worry and trust." Conclusions: Our findings are limited by retrospective interviews and participant homogeneity among other features. Future research with prospective designs and diverse groups of people at risk for and diagnosed with oral tongue cancer, as well as targeting those who have had negative biopsies with no eventual diagnosis of oral tongue cancer, will build on our findings. Further, study of patient experience in other sociocultural context and healthcare systems is needed to inform nursing science and practice. Finally, "living in limbo" suggests that clinician and public education about oral tongue cancer diagnosis is needed.

    2013-11-01

    Exercise-induced laryngeal obstructions (EILOs) cause exercise-related respiratory symptoms (ERRS) and are important differential diagnoses to exercise-induced asthma. The diagnostic method for EILOs includes provocation to induce the obstruction followed by a verification of the obstruction and the degree thereof. The objective of the present study was to examine if a eucapnic voluntary hyperventilation (EVH) test could induce laryngeal obstructions laryngoscopically identical in subtypes and development as seen during an exercise test. EVH and exercise testing with continuous laryngoscopy were performed during a screening of two national athletic teams (n = 67). The laryngoscopic recordings were examined for usability, abnormalities and maximal supraglottic and glottic obstruction using two currently available methods (Eilomea and CLE-score). The participants were asked questions on ERRS, and whether the symptoms experienced during each provocation matched those experienced during regular training. A total of 39 completed both tests. There were no significant differences in subtypes and development thereof, the experience of symptoms, and specificity and sensitivity between the methods. Significantly more recordings obtained during the exercise test were usable for evaluation primarily due to resilient mucus on the tip of the fiber-laryngoscope in the EVH test. Only recordings of six athletes from both provocation methods were usable for evaluation using the Eilomea method (high-quality demand). Amongst these, a linear correlation was found for the glottic obstruction. EVH tests can induce EILOs. However, the present test protocol needs adjustments to secure better visualisation of the larynx during provocation.

  16. Errors in quantum tomography: diagnosing systematic versus statistical errors

    Langford, Nathan K.

    2013-03-01

    A prime goal of quantum tomography is to provide quantitatively rigorous characterization of quantum systems, be they states, processes or measurements, particularly for the purposes of trouble-shooting and benchmarking experiments in quantum information science. A range of techniques exist to enable the calculation of errors, such as Monte-Carlo simulations, but their quantitative value is arguably fundamentally flawed without an equally rigorous way of authenticating the quality of a reconstruction to ensure it provides a reasonable representation of the data, given the known noise sources. A key motivation for developing such a tool is to enable experimentalists to rigorously diagnose the presence of technical noise in their tomographic data. In this work, I explore the performance of the chi-squared goodness-of-fit test statistic as a measure of reconstruction quality. I show that its behaviour deviates noticeably from expectations for states lying near the boundaries of physical state space, severely undermining its usefulness as a quantitative tool precisely in the region which is of most interest in quantum information processing tasks. I suggest a simple, heuristic approach to compensate for these effects and present numerical simulations showing that this approach provides substantially improved performance.

    2012-03-01

    The past 60 years have seen huge advances in many of the scientific, technological and managerial factors that should tend to raise the efficiency of commercial drug research and development (RD). Yet the number of new drugs approved per billion US dollars spent on RD has halved roughly every 9 years since 1950, falling around 80-fold in inflation-adjusted terms. There have been many proposed solutions to the problem of declining RD efficiency. However, their apparent lack of impact so far and the contrast between improving inputs and declining output in terms of the number of new drugs make it sensible to ask whether the underlying problems have been correctly diagnosed. Here, we discuss four factors that we consider to be primary causes, which we call the 'better than the Beatles' problem; the 'cautious regulator' problem; the 'throw money at it' tendency; and the 'basic research-brute force' bias. Our aim is to provoke a more systematic analysis of the causes of the decline in RD efficiency.

    Full Text Available Depressive Episoden sind die häufigsten psychiatrischen Komplikationen bei MP, erschweren oft wesentlich dessen Verlauf und setzen die Lebensqualität der Patienten weiter herab. Als mögliche Risikofaktoren für die Entstehung einer depressiven Symptomatik bei MP gelten: junges Lebensalter und jugendlicher Ausbruch des MP, weibliches Geschlecht, rechtsseitiger Hemiparkinsonismus, zunehmender Schweregrad der körperlichen Beeinträchtigung, Akinesie, Angst und psychotische Symptomatik. Durch die große Überschneidung von Symptomen des MP und der Depression kann es schwierig sein, die Diagnose "Depression bei MP" zu stellen. Der Neuropsychiater sollte diese Komplikation bei MP erwarten bzw. suchen. Pathophysiologisch korreliert die Depression bei Patienten mit MP sowohl mit dem Mangel an Dopamin als auch mit der Beeinträchtigung serotonerger und noradrenerger Neurotransmission. Eine nicht unwesentliche Ursache der Depression bei MP ist auch der Streß, den eine behindernde, chronische und unheilbare Erkrankung subjektiv im Patienten erzeugt. Obwohl die Depression einen entscheidenden Einfluß auf die Lebensqualität der Patienten und ihrer Angehörigen hat und der Behandlung daher ein wichtiger Stellenwert zukommt, wurden bis zum heutigen Tag nur unzureichende Untersuchungen zur Therapie der Depression bei MP durchgeführt. Für die Zukunft gilt es, anhand der Ergebnisse von randomisierten, doppelblinden Studien, Behandlungsalgorithmen für die Therapie der Depression bei Patienten mit MP zu entwickeln.

    X ray spectroscopy is used on the NIF to diagnose the plasma conditions in the ignition target in indirect drive ICF implosions. High-energy emission spectra from mid to high atomic number elements can provide estimates of electron temperature near stagnation of an ICF implosion. A platform is being developed at NIF where small traces of krypton are used as a dopant to the fuel gas for spectroscopic diagnostics using krypton line emissions. The fraction of krypton dopant was varied in the experiments and was selected so as not to perturb the implosion. Simulations of the krypton spectra using a 1 in 104 atomic fraction of krypton in direct-drive exploding pusher with a range of electron temperatures and densities show discrepancies when different atomic models are used. We use our non-LTE atomic model with a detailed fine-structure level atomic structure and collisional-radiative rates to investigate the krypton spectra at the same conditions. Synthetic spectra are generated with a detailed multi-frequency radiation transport scheme from the emission regions of interest to analyze the experimental data and compare and contrast with the existing simulations at LLNL.

    It is standard practice in high school athletic programs for certified athletic trainers to evaluate and treat injured student athletes. In some cases, a trainer refers an athlete to a physician for definitive medical management. This study was conducted to determine the rate of agreement between athletic trainers and physicians regarding assessment of injuries in student athletes. All high school athletes who were injured between 2010 and 2012 at 5 regional high schools were included in a research database. All patients who were referred for physician evaluation and treatment were identified and included in this analysis. A total of 286 incidents met the inclusion criteria. A total of 263 (92%) of the athletic trainer assessments and physician diagnoses were in agreement. In the 23 cases of disagreement, fractures and sprains were the most common injuries. Kappa analysis showed the highest interrater agreement in injuries classified as dislocations and concussions and the lowest interrater agreement in meniscal/labral injuries and fractures. In the absence of a confirmed diagnosis, agreement among health care providers can be used to infer accuracy. According to this principle, as agreement between athletic trainers and physicians improves, there is a greater likelihood of arriving at the correct assessment and treatment plan. Athletic trainers are highly skilled professionals who are well trained in the evaluation of athletic injuries. The current study showed that additional training in identifying fractures may be beneficial to athletic trainers and the athletes they treat. [Orthopedics. 2016; 39(5):e944-e949.].

    Cleidocranial dysplasia (CCD) is a rare congenital disorder, typically characterized by persistently open skull sutures, aplastic or hypoplastic clavicles, and supernumerary teeth. Mutations in the gene encoding the runt-related transcription factor 2 (RUNX2) protein are responsible for approximately two thirds of CCD patients. We report a 20-year-old CCD patient presenting not only with typical skeletal changes, but also complex dental anomalies. A previously undiagnosed odontoma, 14 supernumerary teeth, a cystic lesion, and previously unreported fused primary teeth were discovered on cone-beam computed tomography (CBCT) scans. Mutation analysis identified the causal c.578G>A (p.R193Q) mutation in the RUNX2 gene. At 20 years of age, the patient had already missed the optimal period for dental intervention. This report describes the complex dental anomalies in a belatedly diagnosed CCD patient, and emphasizes the significance of CBCT assessment for the detection of dental anomalies and the importance of early treatment to achieve good outcomes.

    Purpose The aim of this study is to describe seizure as a presenting symptom in individuals with recently diagnosed neurocysticercosis (NCC). Methods Using logistic regression, we examined the probability of having seizures as a presenting symptom among those with active or transitional NCC by host age and gender, and by number of cysts, location of the cysts in the brain, and phase of evolution of the encysted parasite. Results We found that the odds of having seizures as presenting symptom for those in the youngest age group (3–24 years old) were 12.9 times that of the oldest participants (age 55–82 years) (p=0.006). People with cysts in parenchymal locations had a significantly higher odds of seizures compared to those with all their cysts elsewhere (ventricles or subarachnoid) (OR=6.2, p=0.028); and the number of cysts was significantly associated with having seizures (OR=1.1, p=0.026). Host gender and cyst phase were not significantly associated with having seizures after adjusting for confounders and covariates. Conclusion Children, those with cysts in parenchymal locations, and those with a higher number of cysts appear to be more likely to experience seizure when they have NCC cysts in the active or transitional stage.

    In this paper we examine the problem of monitoring and diagnosing noisy complex dynamical systems that are modeled as hybrid systems-models of continuous behavior, interleaved by discrete transitions. In particular, we examine continuous systems with embedded supervisory controllers that experience abrupt, partial or full failure of component devices. Building on our previous work in this area (MBCG99;MBCG00), our specific focus in this paper ins on the mathematical formulation of the hybrid monitoring and diagnosis task as a Bayesian model tracking algorithm. The nonlinear dynamics of many hybrid systems present challenges to probabilistic tracking. Further, probabilistic tracking of a system for the purposes of diagnosis is problematic because the models of the system corresponding to failure modes are numerous and generally very unlikely. To focus tracking on these unlikely models and to reduce the number of potential models under consideration, we exploit logic-based techniques for qualitative model-based diagnosis to conjecture a limited initial set of consistent candidate models. In this paper we discuss alternative tracking techniques that are relevant to different classes of hybrid systems, focusing specifically on a method for tracking multiple models of nonlinear behavior simultaneously using factored sampling and conditional density propagation. To illustrate and motivate the approach described in this paper we examine the problem of monitoring and diganosing NASA's Sprint AERCam, a small spherical robotic camera unit with 12 thrusters that enable both linear and rotational motion.

    Several epidemiological studies suggest a possible involvement of viral infection in the development of epilepsy. While recent research from in vitro studies increasingly supports the role of herpes simplex virus type 1 (HSV-1) in the pathogenesis of epilepsy, little is known about the role of other viral infections such as influenza. Using data from the Clinical Practice Research Datalink (CPRD), we conducted a matched case-control analysis to assess the association between GP-diagnosed influenza infections and the risk of developing an incident diagnosis of epilepsy. During the study period 11 244 incident epilepsy cases and 44 976 matched control patients were identified. Prior exposure to influenza was reported in 7·5% of epilepsy cases and 6·7% of controls [adjusted odds ratio (aOR) 1·12, 95% confidence interval (CI) 1·03-1·22]. Prior history of 'complicated influenza', i.e. influenza associated with a possible super-infection, was associated with a slightly increased epilepsy risk (aOR 1·64, 95% CI 1·10-2·46), particularly if recorded within the 2 months preceding the epilepsy diagnosis (aOR 6·03, 95% CI 1·10-33·2). Our findings suggest that prior influenza exposure does not appear to materially alter the risk of developing epilepsy. By contrast, influenza episodes accompanied by complications were associated with a slightly increased epilepsy risk.

    The certainty of the initial diagnosis of epilepsy was assessed prospectively by one neurologist in outpatients. One hundred and fifty-eight consecutive referrals with loss of consciousness or possible epilepsy were seen. The relative contributions to the initial diagnosis from the referral letter, history taking in clinic, physical examination, and investigation were compared. There was a referring diagnosis in 28.5%. The neurologist reached a diagnosis in 87% of the 158 cases: in 43% epilepsy, 25% syncope, 12% non-epileptic seizures and in 7% other diagnoses. There was a low correlation between referral and specialist diagnosis. Physical examination did not change the diagnosis in any patient. Investigations changed the diagnosis in one patient. Neuro-imaging revealed a relevant abnormality in 12/43 (27.9%) scanned. The yield from EEG was 7/25 (28%), but the EEG changed the diagnosis in only one case. Cardiac testing confirmed the type of syncope in 2/47 (4.3%) of patients. Blood tests did not contribute to the diagnosis in any patient. The neurology consultation significantly increased diagnostic certainty. The diagnosis of epilepsy remains largely clinical. It is important that patients are aware of this prior to investigation.

    The purpose of this study was to assess the prevalence of dissociative disorders in a sample of Chinese psychiatric inpatients. Participants in the study were 569 consecutively admitted inpatients at Shanghai Mental Health Center, China, of whom 84.9% had a clinical diagnosis of schizophrenia based on the Chinese Classification and Diagnostic Criteria of Mental Disorders, Version 3. All participants completed a self-report measure of dissociation (the Dissociative Experiences Scale), and none had a prior diagnosis of a dissociative disorder. A total of 96 randomly selected participants were interviewed with a structured interview (the Dissociative Disorders Interview Schedule) and a clinical interview. These 96 patients did not differ significantly from the 473 patients who were not interviewed on any demographic measures or who did not complete the self-report dissociation measure. A total of 28 patients (15.3%, after weighting of the data) received a clinical diagnosis of a dissociative disorder based on Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.) criteria. Dissociative identity disorder was diagnosed in 2 patients (0.53%, after weighting). Compared to the patients without a dissociative disorder, patients with dissociative disorders were significantly more likely to report childhood abuse (57.1% vs. 22.1%), but the 2 groups did not differ significantly on any demographic measures. Dissociative disorders were readily identified in an inpatient psychiatric population in China.

    Full Text Available BACKGROUND Conventional methods used to diagnose or rule out myocarditis is not useful in detecting cardiac myocyte injury in clinically suspected cases. Endomyocardial biopsy and histopathological examination is not feasible in most government hospitals in India. Sensitive parameters have yet to be found out. The study was conducted to find out whether diagnosis of myocarditis in clinically suspected cases can be done by measurement of serum levels of cardiac troponinI (cTnI and MB isoform of creatine kinase (CK-MB. MATERIALS AND METHODS 19 patients with clinically suspected myocarditis were screened for CK-MB activity and cTnI. Echocardiography, ECG and IgM for leptospirosis were also checked in these patients. RESULTS cTnI was elevated in 10 out of 19 patients with clinically suspected myocarditis. CK-MB was elevated in 7 patients. CONCLUSION Elevation of cTnI level in blood can be taken as an indicator of cardiac muscle cell injury in suspected cases of myocarditis.

    Enzyme replacement therapy for Pompe disease, a neuromuscular disorder characterized by lysosomal glycogen storage due to acid α-glucosidase deficiency, has entered the clinic. There is more than ever a need for early and reliable diagnosis. The objective of this review is to present a critical review of the recent literature on laboratory procedures to diagnose Pompe disease by enzymatic assay and DNA analysis. The methods we used were Compilation and expert interpretation of recent and relevant publications. The introduction of new and the updating of existing laboratory procedures have facilitated the diagnosis of Pompe disease (glycogen storage disease type II; acid maltase deficiency; OMIM 232300). With regard to enzymatic analysis, the application of acarbose as inhibitor of maltase-glucoamylase has enabled the use of mixed leukocyte preparations as diagnostic material. The use of glycogen as a natural substrate in the reaction mixture adds to the selectivity of this procedure. Newborn screening is envisaged and facilitated by the introduction of high-throughput procedures. DNA analysis has become an integral part of the diagnostic procedure for confirmation and completion, for carrier detection, and for genetic counseling.

    Cardiac involvement in systemic sarcoidosis sometimes provokes life-threatening ventricular tachyarrhythmia. Steroid administration is one of the fundamental anti-arrhythmia therapies. For an indication of steroid therapy, a definitive diagnosis of sarcoidosis is required.(1)) However, cases that are clearly suspected of cardiac sarcoidosis based on their clinical courses sometimes do not meet the current diagnostic criteria and result in the loss of an appropriate opportunity to perform steroid therapy.Here we report a case that was diagnosed as sarcoidosis by incidental biopsy of an inguinal lymph node during cardiac resuscitation for cardiac tamponade.(2)) While the inguinal lymph node was not swollen on computed tomography, a specimen obtained from an incidental biopsy during the exposure of a femoral vessel for the establishment of extracorporeal cardio-pulmonary resuscitation showed a non-caseating granuloma.This findings suggest a non-swelling lymph node biopsy might be an alternative strategy for the diagnosis for sarcoidosis if other standard strategies do not result in a diagnosis of sarcoidosis.

    The aim of this study was to evaluate the prevalence of diabetic peripheral neuropathy in children and adolescents with type 1 diabetes mellitus and examine whether the neurological examination validly diagnoses diabetic peripheral neuropathy as compared with the gold standard of nerve conduction velocity in these patients. Nerve conduction velocity was measured in an unselected consecutive series of patients aged 8-18 years who had been suffering from type 1 diabetes mellitus for at least 1 year. For the neurological examination, neuropathy disability scores and neuropathy sign scores were used. Of the 39 patients, six (15%) had clinically evident diabetic peripheral neuropathy, whereas nerve conduction velocity testing revealed diabetic peripheral neuropathy in 15 (38%) patients. Sensitivity and specificity of the neurological examination for the diagnosis of diabetic peripheral neuropathy were 40% and 100%, respectively. The corresponding positive and negative predictive values were 100% and 72.7%, respectively. This conclusions from this study are that in children and adolescents with type 1 diabetes mellitus, diabetic peripheral neuropathy is highly prevalent, but in the majority of patients it is subclinical. Sensitivity and negative predictive values of the neurological examination are low. Therefore, routine nerve conduction velocity measurement for the assessment of diabetic peripheral neuropathy appears to be warranted in these patients.

    A new approach, termed the Biofield test, may have the potential to augment the process of diagnosing breast cancer. This technique is based on the analysis of skin surface electrical potentials measured by an array of specially designed sensors which are placed on the breasts. Measurements are recorded noninvasively and then analyzed using pattern recognition algorithms to produce an immediate and objective assessment of breast tissue in vivo. Initial clinical trials suggests that the test can achieve a sensitivity of approximately 90% and a specificity of 40-50%, which indicates that the test might be useful for excluding cancer when it is, in fact, absent. Although research to date has focused on the differential diagnosis of suspicious breast lesions, future applications could include breast cancer screening, close surveillance and diagnosis of recurrent cancers in breasts previously treated with conservative therapy, and monitoring the effectiveness of breast cancer therapies. Improvements and new applications are expected to occur as additional research and validation in actual clinical settings is performed.

    Background A previous study showed that a high percentage of children diagnosed with Hyperkinetic Disorder (HKD) displayed a consistent pattern of motor function problems. The purpose of this study was to investigate the effect of methylphenidate (MPH) on such motor performance in children with HKD Methods 25 drug-naïve boys, aged 8–12 yr with a HKD-F90.0 diagnosis, were randomly assigned into two groups within a double blind cross-over design, and tested with a motor assessment instrument, during MPH and placebo conditions. Results The percentage of MFNU scores in the sample indicating 'severe motor problems' ranged from 44–84%, typically over 60%. Highly significant improvements in motor performance were observed with MPH compared to baseline ratings on all the 17 subtests of the MFNU 1–2 hr after administration of MPH. There were no significant placebo effects. The motor improvement was consistent with improvement of clinical symptoms. Conclusion The study confirmed our prior clinical observations showing that children with ADHD typically demonstrate marked improvements of motor functions after a single dose of 10 mg MPH. The most pronounced positive MPH response was seen in subtests measuring either neuromotor inhibition, or heightened muscular tone in the gross movement muscles involved in maintaining the alignment and balance of the body. Introduction of MPH generally led to improved balance and a generally more coordinated and controlled body movement. PMID:19439096

    1994-06-01

    The inflammatory myopathies include 3 distinct entities, PM, DM, and IBM. These diseases differ clinically, immunopathologically, and in their response to therapies. Although DM and IBM are easy to diagnose on the basis of characteristic clinicopathologic findings, PM still remains a diagnosis of exclusion. A T cell-mediated cytotoxic process in PM and IBM and a complement-mediated microangiopathy in DM, along with the various serologic markers of autoimmunity, are the hallmarks of the underlying autoimmune processes in these groups. Although in uncontrolled studies PM and DM appear to respond to prednisone and immunosuppressive drugs to some degree and for some period of time, IBM is resistant to all therapies. Currently, high-dose intravenous immunoglobulin (IVIG) appears to be an encouraging and safe new modality of treatment for some of these conditions when other therapies have failed. In a controlled study, IVIG has been shown to be effective in DM and, in uncontrolled studies, in some patients with PM or IBM.

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

    Full Text Available Purpose : To analyze spastic dysarthria form in children population dependency of fatigue and faulty posture relationship. Methods: Research performed with the permission of the bioethics committee (RE-BK-063. The Dutch Fatigue Scale (DUFS. Posture in standing was assessed by Hoeger and Kendall. Research subjects n=40. n=20 children diagnosed with spastic dysarthria and n=20 of children without dysarthria. Their age was 10±2.1years. Boys were n=20 and girls - n=20.Results were statistically significant at p<0.05. Microsoft Office 2013, Excel package were used to count a research results. Results: For children with dysarthria fatigue level is more significant that for children without dysarthria; results were statistically significant, p<0.05. Posture disorder for children with dysarthria was statistically significant higher than among children without dysarthria, p<0.05. Conclusions: For children with dysarthria fatigue level is higher than for healthy children, thus for the girls fatigue level is higher than for the boys. Spastic form dysarthria has an impact to a child posture, by creating a direct dependency between posture deformation and skeletal muscle system disease, which decreases muscle power and increasing fatigue for a child. To correct faulty posture thus to decrease fatigue the tight collaboration needed between rehabilitation team members.

    To determine the incidence of delirium in elderly intensive care patients and to compare incidence using two retrospective chart-based diagnostic methods and a hospital reporting measure (ICD-10). Retrospective study. An ICU in a large metropolitan private hospital in Melbourne, Australia. English-speaking participants (n=348) 80+ years, admitted to ICU for >24 hours. Medical files of ICU patients admitted October 2009-October 2012 were retrospectively assessed for delirium using the Inouye chart review method, DSM-IV diagnostic criteria and ICD-10 coding data. General patient characteristics, first onset of delirium symptoms, source of delirium information, administration of delirium medication, hospital and ICU length of stay, 90 day mortality were documented. Delirium was found in 11-29% of patients, the highest incidence identified by chart review. Patients diagnosed with delirium had higher 90 day mortality, and those meeting criteria for all three methods had longer hospital and ICU length of stay. ICU delirium in the elderly is often under-reported and strategies are needed to improve staff education and diagnosis. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available ABSTRACTHyperkinesias are heterogeneous conditions that share the feature of production of involuntary, abnormal, excessive movements. Tremor, dystonia, and chorea are amongst the most common of these phenomena. In this focused review there is a discussion of difficult issues in hyperkinesias. The first one is the differential diagnosis between essential tremor and Parkinson’s disease. They are readily distinguishable in the majority of patients but in a few subjects essential tremor coexist with parkinsonian features whose underlying mechanism remains to be determined. The second topic of the review is dystonic tremor. Although increasingly diagnosed and reported as accounting for the majority of SWEDDs, its diagnostic criteria are ill defined and differentiation from Parkinson’s disease and essential tremor can be challenging. In the last section, there is a discussion of the differential diagnosis of Sydenham’s chorea, the most common cause of chorea in children. In a few patients, vascular disease, systemic lupus erythematosus and primary antiphospholipid antibody syndrome can mimic Sydenham’s chorea.

    The diagnostic criteria of Marfan syndrome (MFS) highlight the importance of a FBN1 mutation test in diagnosing MFS. As genetic sequencing becomes better, cheaper, and more accessible, the expected increase in the number of genetic tests will become evident, resulting in numerous genetic variants that need to be evaluated for disease-causing effects based on database information. The aim of this study was to evaluate genetic variants in four databases and review the relevant literature. We assessed background data on 23 common variants registered in ESP6500 and classified as causing MFS in the Human Gene Mutation Database (HGMD). We evaluated data in four variant databases (HGMD, UMD-FBN1, ClinVar, and UniProt) according to the diagnostic criteria for MFS and compared the results with the classification of each variant in the four databases. None of the 23 variants was clearly associated with MFS, even though all classifications in the databases stated otherwise. A genetic diagnosis of MFS cannot reliably be based on current variant databases because they contain incorrectly interpreted conclusions on variants. Variants must be evaluated by time-consuming review of the background material in the databases and by combining these data with expert knowledge on MFS. This is a major problem because we expect even more genetic test results in the near future as a result of the reduced cost and process time for next-generation sequencing.Genet Med 18 1, 98-102.

    Abstract Xanthogranuloma (XG) of the sellar region is uncommon and is difficult to diagnose based on intraoperative frozen sections. This study is a case presentation and review of the literature, highlighting the need to explore underlying diseases in order to guarantee an accurate patient diagnosis. Herein, we presented the case of a 43-year-old woman who was afflicted with xanthogranuloma of the sellar region; the patient had a history of headache and lengthened menstrual cycles over the 6 months prior to presentation. Endocrinology tests revealed that the patient’s levels of prolactin were high and the MRI of the patient showed a clearly defined sellar mass. As a result, the patient was considered to have prolactinoma prior to undergoing surgery. The tumor was completely removed using a transsphenoidal approach, and intraoperative frozen section revealed histology similar to xanthogranuloma. When the tumor was removed by surgical operation, the patient’s visual field defects and headache were relieved. Although intraoperative frozen section should provide some guidance with regard to the diagnosis, a pathological study is conducted to confirm the actual diagnosis. PMID:28352831

    Full Text Available A connectionist expert system (CES called BIONET aimed at assisting physicians in the diagnosis of diseases, such as neck and arm pain has been proposed. BIONET is an artificial network or connectionist network model capable of classifying diseases. Need for the development of CES for defence personnel has been discussed: BIONET is a feedforward three layer neural network with one hidden layer. The input, layer has been designated as stimulus layer, the hidden layer as receptor layer and output layer ag cortical layer. The sequential connections with spatial orientation have been maintained between stimulus layer and receptor layer for each specific factor. Parallel connections are established only at the cortical layer. Direct firing and facilitatory and inhibitory mechanisms are adhered to the neurophysiology of human nervous system. An algorithm for training on BIONET is also given. BIONET is simulated on a digital computer with training samples of patients collected from various hospitals in Tamil Nadu to diagnose neck and arm pain,diseases for testing purpose.

    Full Text Available Introduction: Based on the hypothesis that neurovascular events involving in the pathophysiology of migraine can cause hearing loss by influencing blood flow of inner ear, it was aimed to determine whether migraine with or without aura in our clinics patients are at risk for hearing loss by assessing hearing levels via a high-frequency audiometry, acoustic reflex and transient otoacoustic emission responses; to discriminate whether hearing loss is cochlear or retrocochlear originated, if present; and to evaluate whether or not migraine treatment affect hearing level in patients received treatment for migraine in this study. Materials and Methods: The study included patients who were diagnosed as migraine between December 2011 and December 2012 at Neurology Department of Cumhuriyet University, Medicine School according to ICD-II classification and accepted to receive medical therapy. In all patients, hearing levels were measured at baseline and after treatment by using high-frequency audiometry, transient otoacoustic emission and acoustic reflex tests. Results: In the present study, hearing thresholds measured in the right ear was normal in migraine patients with or without aura at baseline, while mild hearing loss was detected in right ear at the frequency of 500 Hz after treatment when hearing thresholds at different frequencies were compared. This difference was significant (P 0, 05. Conclusion: Differently from literature, hearing loss in our patients developed at lower frequencies and after treatment. The results we obtained from our study also presented that there might be a relationship between migraine disease and sensorineural hearing loss.

    Celiac disease (CD) in children may occur with a wide spectrum of clinical manifestations: anemia is the most frequent extraintestinal manifestation, iron deficiency anemia (IDA) is the common presentation. In our study we aimed to assess IDA condition in a large cohort of pediatric patients with newly diagnosed CD. Our study includes a cohort of 518 children (340 females and 178 males), 6 months-18 years old, joined between January 1990 and January 2013. We have analyzed hematological parameters and iron balance: serum iron, serum ferritin and serum transferrin levels. The diagnosis of IDA was considered on the basis of hemoglobin levels below -2SD, associated with serum iron and ferritin reduction, serum transferrin increase; all compared with the normal reference values for age. Of all patients, 156 patients (30.1%) had anemia, including 103 females (19.8%) and 53 males (10.2%); of these, 112 (21.62%) had IDA (in 18 cases associated with α- or β-thalassemia trait), 22 were thalassemic trait without iron deficiency and the remaining 19 suffered from other forms of anemia. One hundred fifteen patients (22.20%) with low ferritin levels but normal hemoglobin levels were considered as preanemic iron deficient patients. Our data confirm that iron depletion and IDA represent a frequent finding at the diagnosis of CD. This significant relation existing between CD and iron deficiency should be considered by pediatricians at the diagnosis of CD in order to treat the patients.

    Full Text Available Tuberculous meningitis (TBM is one of the most serious manifestations of extrapulmonary tuberculosis. Timely and accurate diagnosis provides a favorable prognosis in patients with TBM. The study evaluated the use of multiplex polymerase chain reaction (PCR in the diagnosis of TBM. A study was conducted on 74 patients clinically suspected with TBM. The cerebrospinal fluid (CSF specimens were processed for smear microscopy, middle brook 7H9 culture, and multiplex PCR using primers directed against IS6110 gene and 38 kD protein for detection of Mycobacterium tuberculosis. The results were analyzed to assess the role of multiplex PCR in the diagnosis of TBM. A total of 26 (35.1% patients were diagnosed with TBM. Microscopy was negative in all while culture was positive in two cases only. Comparing with clinical diagnosis and CSF adenosine deaminase levels of ≥10 U/L, multiplex PCR showed sensitivity, specificity, positive predictive value, and negative predictive value of 71.4%, 89.6%, 83.3%, and 81.2%, respectively, in the diagnosis of TBM.

    Full Text Available Malignant infantile osteopetrosis is a rarely seen severe disorder which appears early in life with general sclerosis of the skeleton. It is caused by functionally defective osteoclasts which fail to resorb bone. Affected infants can exhibit a wide spectrum of clinical manifestations including impaired hematopoiesis, hepatosplenomegaly, visual impairment, and hypocalcemia. With the exception of secondary hyperparathyroidism, involvement of the endocrine system seems to be quite rare. Hypopituitarism is defined as underproduction of the growth hormone in combination with deficiencies of other pituitary hormones. Any lesion that damages hypothalamus, pituitary stalk, or anterior pituitary can cause secondary hypopituitarism. In this report, we presented a rare combination of malignant infantile osteopetrosis and secondary hypopituitarism in a newborn who presented predominantly with endocrinological symptoms. This is the first case report of malignant infantile osteopetrosis accompanied by hypopituitarism secondary to sclerosis of the sella turcica. On the other hand, this is a very interesting case which was diagnosed based on histological examination of bone marrow biopsy specimens despite lack of any clinical suspicion.

    Montoya Filardi, A; Guasp Vizcaíno, M; Gómez Fernández-Montes, J; Llorens Salvador, R

    We present a case of cleidocranial dysplasia diagnosed by low-dose fetal computed tomography (CT) in the 25th week of gestation. Severe bone dysplasia was suspected because of the fetus' low percentile in long bones length and the appearance of craniosynostosis on sonography. CT found no abnormalities incompatible with life. The effective dose was 5 mSv, within the recommended range for this type of examination. Low-dose fetal CT is a new technique that makes precision study of the bony structures possible from the second trimester of pregnancy. In Spain, abortion is legal even after the 22nd week of gestation in cases of severe fetal malformations. Therefore, in cases in which severe bone dysplasia is suspected, radiologists must know the strategies for reducing the dose of radiation while maintaining sufficient diagnostic quality, and they must also know which bony structures to evaluate.

    Full Text Available Background. Metabolic syndromes such as Wernicke’s encephalopathy may present with a sudden neurological deficit, thus mimicking acute onset stroke. Due to current emphasis on rapid admission and treatment of acute stroke patients, there is a significant risk that these stroke mimics may end up being treated with thrombolysis. Rigorous clinical and radiological skills are necessary to correctly identify such metabolic stroke mimics, in order to avoid doing any harm to these patients due to the unnecessary use of thrombolysis. Patient. A 51-year-old Caucasian male was admitted to our hospital with suspicion of an acute stroke due to sudden onset dysarthria and unilateral facial nerve paresis. Clinical examination revealed confusion and dysconjugate gaze. Computed tomography (CT including a CT perfusion (CTP scan revealed bilateral thalamic hyperperfusion. The use of both clinical and radiological findings led to correctly diagnosing Wernicke’s encephalopathy. Conclusion. The application of CTP as a standard diagnostic tool in acute stroke patients can improve the detection of stroke mimics caused by metabolic syndromes as shown in our case report.

  12. Diagnosing Air-Sea Interactions on Intraseasonal Timescales

    What is the role of ocean coupling in the Madden Julian Oscillation (MJO)? Consensus thinking holds that the essential physics of the MJO involve interactions between convection, atmospheric wave dynamics, and boundary layer and free troposphere moisture. However, many modeling studies demonstrate improved MJO simulation when an atmosphere-only general circulation model (AGCM) is coupled to an ocean model, so feedbacks from the ocean are probably not negligible. Assessing the importance and processes of these feedbacks is challenging for at least two reasons. First, observations of the MJO only sample the fully coupled ocean-atmosphere system; there is no "uncoupled" MJO in nature. Second, the practice of analyzing the MJO in uncoupled and coupled GCMs (CGCMs) involves using imperfect tools to study the problem. Although MJO simulation is improving in many models, shortcomings remain in both AGCMs and CGCMs, making it difficult to determine if changes brought about through coupling reflect critical air-sea interactions or are simply part of the collective idiosyncracies of a given model. For the atmosphere, ocean feedbacks from intraseasonal sea surface temperature (SST) variations are communicated through their effects on surface fluxes of heat and moisture. This presentation suggests a set of analysis tools for diagnosing the impact of an interactive ocean on surface latent and sensible heat fluxes, including their mean, variance, spectral characteristics, and phasing with respect to wind, SST, and MJO convection. The diagnostics are demonstrated with application to several CMIP5 models, and reveal a variety of responses to coupled ocean feedbacks.

    Full Text Available The goal of the study is to evaluate the sensitivity of Czech physicians to the early diagnosis of dementia in patients with memory impairment.A retrospective observational study was designed. We have reviewed the electronic medical records of patients who have been hospitalized for the first time due to dementia of any type at the Kromeriz Mental hospital from January 1, 2012 to December 31, 2013 (24-month period. Pluralistic methods combining the qualitative and quantitative approach were used in this study.Dementia of any type was diagnosed in 125 patients in the monitored period. The mean time between patient memory complaints and his / her admission to our facility for their first hospitalization due to dementia was 7.1 years (+- 3.7 years. Most patients with dementia had no prior outpatient treatment of their memory impairment (56.2%; a minority of patients (43.8% had treatment of their memory impairment by an outpatient physician.The sensitivity of Czech physicians to the early diagnosis of dementia is very low. Any delay in starting the treatment of dementia means a worsened effectiveness of this treatment, a worsened quality of life of patients with dementia and their caregivers. Our recommendations for both the early diagnosis and treatment of dementia should be involved in guidelines and should become a part of the pregraduate and postgraduate education of all physicians.

    Violence among those diagnosed with schizophrenia has been reported but is not a diagnostic component of the disorder. The position of the courts regarding fulfillment of the requisite intent to commit violent acts has not been extensively reported. This article discusses the impact of a diagnosis of schizophrenia in an individual and how the pharmacist can help integrate information into the health care system. The recent Supreme Court case of Clark versus Arizona and the older case of Patterson versus Cockrell are discussed with respect to the concept of intent (to commit the act) and the implications this has on an individual in the midst of a psychotic episode. Quality of life, the perception of the stigma associated with a diagnosis of schizophrenia, and pharmacotherapy are briefly discussed. The origin of schizophrenia is multifactorial. Persons with schizophrenia are not innately violent, but alteration in perception may precipitate aggressive acts. Given the complex and diverse nature of schizophrenia and the fact that even with successful pharmacological treatment residual symptoms may still be present, there is a need to provide information to health care practitioners and the court.

    To determine the effectiveness and security of the antipsychotics available for the management of adult patients with schizophrenia in the maintenance phase. To develop recommendations of treatment for the maintenance phase of the disease. A clinical practice guideline was elaborated under the parameters of the Methodological Guide of the Ministerio de Salud y Protección Social to identify, synthesize and evaluate the evidence and make recommendations about the treatment and follow-up of adult patients with schizophrenia. The evidence of NICE guide 82 was adopted and updated. The evidence was presented to the Guideline Developing Group and recommendations, employing the GRADE system, were produced. 18 studies were included to evaluate the effectiveness and / or safety of different antipsychotic drugs first and second generation. Overall, antipsychotics (AP) showed superiority over placebo in relapse rate over 12 months (RR 0.59 95% CI 0.42, 0.82) and hospitalization rate over 24 months of follow-up (RR 0.38 95% 0.27, 0.55); its use is associated with increased risk of treatment dropout (RR 0.53 95% CI 0.46, 0.61) and adverse events such as weight gain, dystonia, extrapyramidal symptoms and sedation. There was no difference in the outcome of re hospitalizations, comparisons on quality of life, negative symptoms or weight gain between AP first and second generation. Continuous or standard dose regimens appear to be superior to intermittent or low doses in reducing the risk of abandonment of treatment regimes. Adult patients diagnosed with schizophrenia should receive maintenance treatment with antipsychotics. The medication of choice will depend on the management of the acute phase, the patient's tolerance to it and the presentation of adverse events. Copyright © 2014 Asociación Colombiana de Psiquiatría.

    Full Text Available Background: Preeclampsia is of major complications of pregnancy that is associated with maternal morbidity and mortality. Therefore, prediction and early diagnosis of preeclampsia would be helpful for better controlling of related complications. Our study aimed to investigate risk factors helping to predict and early diagnose of preeclampsia. Materials and Methods: A total of 739 nulliparous women at their 24-28 th weeks of the first pregnancy were enrolled in this multi-center cohort study. Incidence or absence of preeclampsia in this population was evaluated up to the end of pregnancy period. For each case, a record sheet was assigned that contained information about haematocrit level in weeks 24-28 th of pregnancy, blood pressure, result of roll-over test in weeks 24-28 th of pregnancy and the presence of disease up to end of the study. Diagnosis of preeclampsia was made based on gold standard. Results : Overall, 3.9 % of all cases developed preeclampsia. The mean maternal age, body mass index (BMI, years of education and positive roll-over test were significantly higher in preeclampsia group (P < 0.001. However, the mean gestational age and changes in the levels of haematocrit were significantly higher in normotensive cases (P < 0.001. Our combined model could predict preeclampsia with a sensitivity of 93% and a specificity of 80%. Conclusion: Simple combined model of demographic characteristics including maternal age, BMI, years of education and positive roll-over tests can predict preeclampsia without any cost for the patients.

    To examine the capacity of straylight and disk halo size to diagnose cataract. Faculty of Optics and Optometry, Universidad Complutense de Madrid, Spain. Prospective study. Straylight, disk halo radius, and high-contrast corrected distance visual acuity (CDVA) measurements were compared between patients with age-related cataract and age-matched normal-sighted control subjects by calculating the area under the curve (AUC) receiver operating characteristic. Measurements were made in 53 eyes of 53 patients with a mean age of 67.94 years ± 7.11 (SD) and 31 eyes of 31 controls with a mean age 66.06 ± 5.43 years. Significantly worse (P < .001) mean straylight (1.38 ± 0.24 log[s]), mean disk halo radius (2.40 ± 0.18 log minutes of arc [arcmin]), and mean CDVA (0.17 ± 0.11 logMAR) were recorded in the cataract group than in the control group (1.17 ± 0.11 log[s], 2.10 ± 0.16 log arcmin, and 0.08 ± 0.08 logMAR). Significant differences in AUCs were observed for disk halo radius (0.89 ± 0.04) versus straylight (0.77 ± 0.05) (P = .03) and disk halo radius versus CDVA (0.72 ± 0.05) (P = .001). The comparison of disk halo radius versus the discriminant function with input from CDVA and straylight (0.80 ± 0.05) was at the limit of significance only (0.091 ± 0.05, P = .051). Although all 3 variables discriminated well between normal eyes and eyes with cataract, the disk halo radius showed the best diagnostic capacity.

    Gangrenous cholecystitis and perforation are severe complications of acute cholecystitis, which have a challenging preoperative diagnosis. Early identification allows better surgical management. Contrast-enhanced computed tomography (ceCT) is the current diagnostic gold standard. Contrast-enhanced ultrasonography (CEUS) is a promising tool for the diagnosis of gallbladder perforation, but data from the literature concerning efficacy are sparse. The aim of the study was to evaluate CEUS findings in pathologically proven complicated cholecystitis (gangrenous, perforated gallbladder, pericholecystic abscess). A total of 8 patients submitted to preoperative CEUS, and with subsequent proven acute complicated cholecystitis at surgical inspection and pathological analysis, were retrospectively identified. The final diagnosis was gangrenous/phlegmonous cholecystitis (n. 2), phlegmonous/ulcerative changes plus pericholecystic abscess (n. 2), perforated plus pericholecystic abscess (n. 3), or perforated plus pericholecystic biliary collection (n. 1). Conventional US findings revealed irregularly thickened gallbladder walls in all 8 patients, with vaguely defined walls in 7 patients, four of whom also had striated wall thickening. CEUS revealed irregular enhancing gallbladder walls in all patients. A distinct wall defect was seen in six patients, confirmed as gangrenous/phlegmonous cholecystitis at pathology in all six, and in four as perforation at macroscopic surgical inspection. CEUS is a non-invasive easily repeatable technique that can be performed at the bedside, and is able to accurately diagnose complicated/perforated cholecystitis. Despite the limited sample size in the present case series, CEUS appears as a promising tool for the management of patients with the clinical possibility of having an acute complicated cholecystitis.

    Full Text Available Judith E Karp1, Jeffrey E Lancet21Division of Hematologic Malignancies, Johns Hopkins Sidney Kimmel Comprehensive Cancer Center, Baltimore, Maryland, USA; 2H. Lee Moffitt Comprehensive Cancer Center, Tampa, Florida, USAAbstract: Farnesyltransferase inhibitors (FTIs represent a new class of signal transduction inhibitors that block the processing of cellular polypeptides that have cysteine terminal residues and, by so doing, interdict multiple pathways involved in proliferation and survival of diverse malignant cell types. Tipifarnib is an orally bioavailable, nonpeptidomimetic methylquinolone FTI that has exhibited clinical activity in patients with myeloid malignancies including elderly adults with acute myelogenous leukemia (AML who are not candidates for traditional cytotoxic chemotherapy, patients with high-risk myelodysplasia, myeloproliferative disorders, and imatinib-resistant chronic myelogenous leukemia. Because of its relatively low toxicity profile, tipifarnib provides an important alternative to traditional cytotoxic approaches for elderly patients who are not likely to tolerate or even benefit from aggressive chemotherapy. In this review, we will focus on the clinical development of tipifarnib for treatment of newly diagnosed AML, both as induction therapy for elderly adults with poor-risk AML and as maintenance therapy following achievement of first complete remission following induction and consolidation therapies for poor-risk AML. As with all other malignancies, the optimal approach is likely to lie in rational combinations of tipifarnib with cytotoxic, biologic and/or immunomodulatory agents with non-cross-resistant mechanisms of action. Gene expression profi ling has identified networks of differentially expressed genes and gene combinations capable of predicting response to single agent tipifarnib. The clinical and correlative laboratory trials in progress and under development will provide the critical foundations for

    Atmospheric transport of black carbon (BC) from surrounding areas has been shown to impact the Tibetan environment, and clarifying the geographical source and receptor regions is crucial for providing guidance for mitigation actions. In this study, 10 trace volatile organic compounds (VOCs) sampled across Tibet are chosen as proxies to diagnose source regions and related transport of pollutants to Tibet. The levels of these VOCs in Tibet are higher than those in the Arctic and Antarctic regions but much lower than those observed at many remote and background sites in Asia. The highest VOC level is observed in the eastern region, followed by the southern region and the northern region. A positive matrix factorization (PMF) model found that three factors-industry, biomass burning, and traffic-present different spatial distributions, which indicates that different zones of Tibet are influenced by different VOC sources. The average age of the air masses in the northern and eastern regions is estimated to be 3.5 and 2.8 days using the ratio of toluene to benzene, respectively, which indicates the foreign transport of VOC species to those regions. Back-trajectory analyses show that the Afghanistan-Pakistan-Tajikistan region, Indo-Gangetic Plain (IGP), and Meghalaya-Myanmar region could transport industrial VOCs to different zones of Tibet from west to east. The agricultural bases in northern India could transport biomass burning-related VOCs to the middle-northern and eastern zones of Tibet. High traffic along the unique national roads in Tibet is associated with emissions from local sources and neighboring areas. Our study proposes international joint-control efforts and targeted actions to mitigate the climatic changes and effects associated with VOCs in Tibet, which is a climate sensitive region and an important source of global water.
