Selected AbstractsIncidence of seropositivity to bordetella pertussis and mycoplasma pneumoniae infection in patients with chronic laryngotracheitis,THE LARYNGOSCOPE, Issue 9 2009FACS, Mary Es Beaver MD Abstract Objectives/Hypothesis: Determine the incidence of bordetella pertussis and mycoplasma pneumonia infection in patients with chronic laryngotracheitis. Study Design: A prospective case study. Methods: Fifty-four consecutive adult patients presenting with symptoms (throat clearing, hoarseness, cough, globus) and signs (laryngeal and subglottic erythema and edema) of chronic laryngotracheitis (CLTR) for >6 weeks were included in the study. A single blood draw for anti-pertussis toxin IgG, IgA, IgM, and mycoplasma IgM was performed at presentation. Duration of symptoms, symptom score (Reflux Symptom Index [RSI]), and physical exam score were recorded. Results: Thirteen patients (24%) had elevated IgA and IgG to pertussis toxin. Nine patients (17%) had elevated IgM to pertussis toxin. Eight patients (15%) had elevated IgM to mycoplasma pneumoniae. There were no significant differences in symptom duration, RSI score, or Voice Handicap Index-10 score among patients with current infection, recent past infection, or no infection. Subglottic erythema scores were significantly higher for patients with current or recent past infection compared to the no infection group. Patients with current infection or recent past infection had significantly more tracheal erythema than supraglottic or vocal fold erythema. Conclusions: Bordetella pertussis and mycoplasma pneumoniae infection play a significant role in the etiology of CLTR. Pertussis can be a mild but chronic presentation and may not produce typical symptoms of severe cough. Symptom duration and severity cannot differentiate between CLTR of infectious or other etiology. Infection should be considered in patients with CLTR that have significant tracheal erythema. Laryngoscope, 2009 [source] Prevalence of and predictive factors for sustained disease-modifying antirheumatic drug,free remission in rheumatoid arthritis: Results from two large early arthritis cohortsARTHRITIS & RHEUMATISM, Issue 8 2009Diane van der Woude Objective Remission has become an attainable goal of rheumatoid arthritis (RA) treatment, especially since the advent of biologic antirheumatic therapy. Because little is known about patients who achieve disease remission with conventional treatment, we used 2 large independent inception cohorts to study the prevalence of and predictive factors for disease-modifying antirheumatic drug (DMARD),free sustained remission after treatment with conventional therapy. Methods Remission of disease was assessed in 454 patients from the Leiden Early Arthritis Clinic (EAC) and in 895 patients from the British Early Rheumatoid Arthritis Study (ERAS) who fulfilled the American College of Rheumatology 1987 revised criteria for the classification of RA and were treated with conventional therapy. Sustained DMARD-free remission was defined as fulfilling the following criteria for at least 1 year: 1) no current DMARD use, 2) no swollen joints, and 3) classification as DMARD-free remission by the patient's rheumatologist. Predictive factors were identified by Cox regression analysis. Results Sustained DMARD-free remission was achieved by 68 of 454 patients (15.0%) in the Leiden EAC and by 84 of 895 patients (9.4%) in the ERAS. Six factors were associated with sustained DMARD-free remission in both cohorts: acute onset, short symptom duration before inclusion, not smoking, little radiographic damage at baseline, absence of IgM rheumatoid factor (IgM-RF), and absence of HLA shared epitope alleles. In the ERAS, low disease activity at baseline was also predictive of remission. Multivariate analyses revealed symptom duration and the absence of autoantibodies (anti,cyclic citrullinated peptide 2 and IgM-RF) as independent predictors. Conclusion Sustained DMARD-free remission in RA patients treated with conventional therapy is not uncommon. Symptom duration at presentation and the absence of autoantibodies are associated with sustained DMARD-free remission. [source] Color Doppler sonography examination of partially obstructed kidneys associated with ureteropelvic junction stone before and after percutaneous nephrolithotripsy: Preliminary reportINTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2005SÜLEYMAN KILIÇ Abstract Aim: To evaluate resistive index (RI) changes before and after unilateral percutaneous nephrolithotripsy in chronic partially obstructed kidneys due to ureteropelvic junction (UPJ) stones. Methods: Intrarenal RI of obstructed and contralateral normal kidneys of 18 patients were recorded immediately before the operations and at postoperative days 1, 7 and 30. Postoperative RI measurements were compared with baseline values for all patients without grouping and separately for different groups according to the preoperative RI value of the obstructed kidney. Results: Mean age and symptom duration were 27.5 years and 43.8 weeks, respectively. Preoperatively and at all postoperative controls, kidney diameters and renal parenchyma thicknesses were normal in all patients. Mean RI of obstructed kidneys decreased from 0.68 to 0.63 for all patients (P = 0.032), from 0.64 to 0.63 for those with preoperative RI < 0.70 (P = 0.850) and from 0.73 to 0.62 for those with preoperative RI , 0.70 (P = 0.001). In patients with preoperative RI , 0.70 in obstructed kidney, significant RI decreases were recorded at postoperative day 7 and RI differences between obstructed and contralateral kidneys disappeared after then. No difference was present pre- and postoperatively between the mean RI of obstructed and contralateral kidneys of the patients with RI < 0.70. Mean RI of contralateral kidneys were normal preoperatively and showed no significant change postoperatively. Conclusions: Preoperative RI levels may indirectly reflect the presence of functionally significant obstruction in chronic obstructed kidneys related to UPJ stones. Patients with RI , 0.70 may have a good indication for a surgical approach. Normalization of high RI occurs rapidly after percutaneous nephrolithotripsy. [source] The Effect of Insomnia Definitions, Terminology, and Classifications on Clinical PracticeJOURNAL OF AMERICAN GERIATRICS SOCIETY, Issue S7 2005Andrew D. Krystal MD There is a need for newer, more clinically useful classifications for insomnia. Identification of specific subtypes of insomnia helps anchor research, allows for prediction of prognosis/course of the condition, and may allow for individualization of treatment. Existing classifications differ, and many terms remain inadequately defined, which leads to diagnostic confusion. Historically, insomnia has been classified according to symptom type, symptom duration, and underlying cause, but these classifications have not been based on evidence of their utility, and newer research suggests the need for change. Symptoms may include difficulty falling asleep, trouble staying asleep, and not feeling restored by sleep, although it has not been clear that it is possible to identify distinct subtypes of patients by symptom or that distinguishing symptom type affects the course of clinical treatment. Classification of insomnia by duration most commonly involves three categories: transient (no more than a few days), short-term (up to 3 weeks), and long-term (more than 3 weeks). This categorization is of uncertain utility and has been primarily based on nonempiric concerns about treatment with sedative-hypnotic medications for periods longer than several weeks. The subtyping of insomnia in terms of whether there is an identifiable underlying cause such as a psychiatric or medical illness was based on an unproven assumption that in most instances other disorders caused insomnia. Recent studies suggest the need to revisit these classification strategies. Evidence that symptom types typically overlap and change over time complicates the categorization of subjects by whether they have difficulty falling asleep or staying asleep or have nonrestorative sleep. New studies of the treatment of chronic insomnia change the perspective on duration of treatment and, as a result, classification of duration of disease. Two studies of nightly pharmacotherapy for insomnia including more than 800 insomnia patients have not identified any increase in the risks after 3 to 4 weeks of treatment. In addition, nonpharmacological treatments demonstrate long-lasting efficacy in patients with chronic insomnia, and the development of abbreviated cognitive-behavioral therapies, which are particularly well suited to primary care practice, have improved their applicability. Newer studies of the relationships between insomnia and associated medical and psychiatric conditions undermine the notion that insomnia is always a symptom and caused by an underlying condition. They suggest that, although it is important to identify and treat these conditions, this may not be sufficient to alleviate the insomnia, which may adversely affect the course of the associated disorder. As a result, treatment targeted specifically to the insomnia should be considered. All of these developments point to an increasing ability to tailor therapy to the particular needs of patients and to optimize the clinical management of insomnia. [source] Somatic awareness, uncertainty, and delay in care-seeking in acute heart failureRESEARCH IN NURSING & HEALTH, Issue 2 2006Corrine Y. Jurgens Abstract Symptom monitoring is difficult for heart failure (HF) patients. Difficulties physically sensing and determining symptom meaning may lead to uncertainty and delay treatment. Somatic awareness may provide insight into symptom monitoring ability. A model combining physical and cognitive aspects of the symptom experience was developed to examine factors affecting care-seeking among HF patients. Adults hospitalized with acute HF were interviewed and completed questionnaires measuring somatic awareness and uncertainty. HF symptom duration prior to admission measured delay. HF specific somatic awareness and symptom pattern predicted delay. Uncertainty correlated with somatic awareness, but did not predict delay. Few responded to early HF symptoms delaying until acutely ill. Development of interventions to improve symptom monitoring is needed. © 2006 Wiley Periodicals, Inc.

Conclusions: Bordetella pertussis and mycoplasma pneumoniae infection play a significant role in the etiology of CLTR. Pertussis can be a mild but chronic presentation and may not produce typical symptoms of severe cough. Symptom duration and severity cannot differentiate between CLTR of infectious or other etiology. Infection should be considered in patients with CLTR that have significant tracheal erythema. Laryngoscope, 2009 [source] The diagnostic utility of magnetic resonance imaging in spondylarthritis: An international multicenter evaluation of one hundred eighty-seven subjectsARTHRITIS & RHEUMATISM, Issue 10 2010Ulrich Weber Objective To systematically assess the diagnostic utility of magnetic resonance imaging (MRI) to differentiate patients with spondylarthritis (SpA) from patients with nonspecific back pain and healthy volunteers, using a standardized evaluation of MR images of the sacroiliac joints. Methods Five readers blinded to the patients and diagnoses independently assessed MRI scans (T1-weighted and STIR sequences) of the sacroiliac joints obtained from 187 subjects: 75 patients with ankylosing spondylitis (AS; symptom duration ,10 years), 27 patients with preradiographic inflammatory back pain (IBP; mean symptom duration 29 months), 26 patients with nonspecific back pain, and 59 healthy control subjects; all participants were age 45 years or younger. Bone marrow edema, fat infiltration, erosion, and ankylosis were recorded according to standardized definitions using an online data entry system. We calculated sensitivity, specificity, and positive and negative likelihood ratios (LRs) for the diagnosis of SpA based on global assessment of the MRI scans. Results Diagnostic utility was high for all 5 readers, both for patients with AS (sensitivity 0.90, specificity 0.97, positive LR 44.6) and for patients with preradiographic IBP (sensitivity 0.51, specificity 0.97, positive LR 26.0). Diagnostic utility based solely on detection of bone marrow edema enhanced sensitivity (67%) for patients with IBP but reduced specificity (88%); detection of erosions in addition to bone marrow edema further enhanced sensitivity (81%) without changing specificity. A single lesion of the sacroiliac joint on MRI was observed in up to 27% of control subjects. Conclusion This systematic and standardized evaluation of sacroiliac joints in patients with SpA showed that MRI has much greater diagnostic utility than has been documented previously. We present for the first time a data-driven definition of MRI-visualized positivity for SpA.

This work was undertaken to develop new classification criteria for RA. Methods A joint working group from the ACR and the European League Against Rheumatism developed, in 3 phases, a new approach to classifying RA. The work focused on identifying, among patients newly presenting with undifferentiated inflammatory synovitis, factors that best discriminated between those who were and those who were not at high risk for persistent and/or erosive disease,this being the appropriate current paradigm underlying the disease construct "rheumatoid arthritis." Results In the new criteria set, classification as "definite RA" is based on the confirmed presence of synovitis in at least 1 joint, absence of an alternative diagnosis that better explains the synovitis, and achievement of a total score of 6 or greater (of a possible 10) from the individual scores in 4 domains: number and site of involved joints (score range 0,5), serologic abnormality (score range 0,3), elevated acute-phase response (score range 0,1), and symptom duration (2 levels; range 0,1). Conclusion This new classification system redefines the current paradigm of RA by focusing on features at earlier stages of disease that are associated with persistent and/or erosive disease, rather than defining the disease by its late-stage features. This will refocus attention on the important need for earlier diagnosis and institution of effective disease-suppressing therapy to prevent or minimize the occurrence of the undesirable sequelae that currently comprise the paradigm underlying the disease construct "rheumatoid arthritis." [source] Do rheumatoid arthritis and lymphoma share risk factors?: A comparison of lymphoma and cancer risks before and after diagnosis of rheumatoid arthritisARTHRITIS & RHEUMATISM, Issue 5 2010Karin Hellgren Objective Patients with rheumatoid arthritis (RA), in particular those with the most severe disease, are at increased risk of developing malignant lymphoma. Whether this increase is entirely a consequence of the RA disease and/or its treatment or is reflective of shared susceptibility to the two diseases remains unclear. We undertook this study to assess whether patients with RA are already at increased risk of lymphoma or of other cancers before the diagnosis of RA, and if the relative risk increases with time since RA diagnosis. Methods Patients with incident RA (symptom duration <1 year) (n = 6,745) registered in the Swedish Early Arthritis Registry from 1997 through 2006 were identified. For each patient, 5 general population controls were randomly matched by sex, age, marital status, and residence (n = 33,657). For all study subjects, inclusion in the nationwide Swedish Cancer Register in 1958,2006 was determined. Relative risks (RRs) (with 95% confidence intervals [95% CIs]) of lymphoma and of cancer overall, before and after diagnosis of RA, were estimated using conditional logistic regression and Cox regression, respectively. Results Before diagnosis of RA, there was no observed increase in the risk of lymphoma (RR [odds ratio] 0.67 [95% CI 0.37,1.23]) or other cancers (RR 0.78 [95% CI 0.70,0.88]). During the first 10 years following diagnosis of RA, the overall RR (hazard ratio) of lymphoma development was 1.75 (95 % CI 1.04,2.96). Conclusion These findings indicate that overall, a history of cancer, including lymphoma, does not increase the risk of subsequent RA development. Shared susceptibility to RA and lymphoma may thus be of limited importance. In contrast, increased lymphoma risks were observed within the first decade following RA diagnosis.

[source] The early disease stage in axial spondylarthritis: Results from the german spondyloarthritis inception cohort,ARTHRITIS & RHEUMATISM, Issue 3 2009Martin Rudwaleit Objective Ankylosing spondylitis (AS) is diagnosed late, because radiographs of the sacroiliac joints often do not show definite sacroiliitis at the time of disease onset. The aim of this study was to investigate whether patients without definite radiographically defined sacroiliitis, referred to as nonradiographic axial spondylarthritis (SpA), are different from patients with AS with regard to clinical manifestations and disease activity measures. Moreover, we sought to identify determinants of the development of radiographic sacroiliitis. Methods In a cross-sectional analysis of 462 patients, we compared 226 patients with nonradiographic axial SpA (symptom duration ,5 years) and 236 patients with AS (symptom duration ,10 years) who are participants in the German Spondyloarthritis Inception Cohort. Radiographs of the sacroiliac joints and the spine were assessed by 2 readers in a blinded manner. Logistic regression analysis was applied to identify parameters associated with structural damage. Results The 2 groups did not differ in the frequency of HLA,B27 positivity, inflammatory back pain, arthritis, enthesitis, and uveitis and had similar levels of disease activity, using measures such as the Bath Ankylosing Spondylitis Disease Activity Index. In both groups, HLA,B27 positivity determined the age at disease onset. Male sex (adjusted odds ratio [OR] 2.38, 95% confidence interval [95% CI] 1.19,4.73 [P = 0.014]) and an elevated C-reactive protein (CRP) level (adjusted OR 1.85, 95% CI 0.96,3.56 [P = 0.066]) were associated with radiographic sacroiliitis. In patients with AS, male sex and an elevated CRP level were also associated with the presence of syndesmophytes. Conclusion Clinical manifestations and disease activity measures are highly comparable between patients with early nonradiographic axial SpA and those with early AS, suggesting that these 2 entities are part of the same disease. Male sex and an elevated CRP level are associated with structural damage on radiographs, whereas HLA,B27 positivity determines the age at disease onset. [source] How to diagnose rheumatoid arthritis early: A prediction model for persistent (erosive) arthritisARTHRITIS & RHEUMATISM, Issue 2 2002Henk Visser Objective To develop a clinical model for the prediction, at the first visit, of 3 forms of arthritis outcome: self-limiting, persistent nonerosive, and persistent erosive arthritis. Methods A standardized diagnostic evaluation was performed on 524 consecutive, newly referred patients with early arthritis. Potentially diagnostic determinants obtained at the first visit from the patient's history, physical examination, and blood and imaging testing were entered in a logistic regression analysis. Arthritis outcome was recorded at 2 years' followup. The discriminative ability of the model was expressed as a receiver operating characteristic (ROC) area under the curve (AUC). Results The developed prediction model consisted of 7 variables: symptom duration at first visit, morning stiffness for ,1 hour, arthritis in ,3 joints, bilateral compression pain in the metatarsophalangeal joints, rheumatoid factor positivity, anti,cyclic citrullinated peptide antibody positivity, and the presence of erosions (hands/feet). Application of the model to an individual patient resulted in 3 clinically relevant predictive values: one for self-limiting arthritis, one for persistent nonerosive arthritis, and one for persistent erosive arthritis. The ROC AUC of the model was 0.84 (SE 0.02) for discrimination between self-limiting and persistent arthritis, and 0.91 (SE 0.02) for discrimination between persistent nonerosive and persistent erosive arthritis, whereas the discriminative ability of the American College of Rheumatology 1987 classification criteria for rheumatoid arthritis was significantly lower, with ROC AUC values of 0.78 (SE 0.02) and 0.79 (SE 0.03), respectively. Conclusion A clinical prediction model was developed with an excellent ability to discriminate, at the first visit, between 3 forms of arthritis outcome. Validation in other early arthritis clinics is necessary. [source] Quality of life and acceptability of medical versus surgical management of early pregnancy failure,BJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 4 2008B Harwood Objective, This study compares quality of life (QOL) and acceptability of medical versus surgical treatment of early pregnancy failure (EPF). Design, A randomised clinical trial of treatment for EPF compared misoprostol vaginally versus vacuum aspiration (VA). Setting, A multisite trial at four US Urban University Hospitals. Population, A total of 652 women with an EPF were randomised to treatment. Methods, Participants completed a daily symptom diary and a questionnaire 2 weeks after treatment. Main outcome measures, The questionnaire assessment included subscales of the Short Form-36 Health Survey Revised for QOL and measures of wellbeing, recovery difficulties, and treatment acceptability. Results, The two groups did not differ in mean scores for QOL except bodily pain; medical treatment was associated with higher levels of bodily pain than VA (P < 0.001). Success of treatment was not related to QOL, but acceptability of the procedure was decreased for medical therapy if unsuccessful (P = 0.003). Type of treatment was not associated with differences in recovery, and the two groups reported similar acceptability except for cramping (P = 0.02), bleeding (P < 0.001), and symptom duration (P = 0.03). Conclusions, Despite reporting greater pain and lower acceptability of treatment-related symptoms, QOL and treatment acceptability were similar for medical and surgical treatment of EPF. Acceptability, but not QOL, was influenced by success or failure of medical management. [source] Targets and elective colorectal cancer: outcome and symptom delay at surgical resectionCOLORECTAL DISEASE, Issue 2 2005S. Bharucha Abstract Objective To determine, for elective patients with colorectal cancer, if associations exist between the length of symptom history at surgical resection and Dukes stage, completeness of the surgical procedure and patient survival. Patients and methods A prospective cohort study was undertaken. Five hundred and eighty-two patients with colorectal cancer, admitted for surgical resection after outpatient consultation, divided into four equal quartiles according to length of symptom history (short: n = 131, 0,103 days; medium: n = 136, 104,177 days; long: n = 136, 178,318 days; very long: n = 137, 319,1997 days). The main outcome measures used were the Extent of tumour (Dukes stage) at resection, completeness of resectional surgery (curative vs palliative), patient survival after resection. Results For patients undergoing elective surgical resection of colorectal cancer we did not find an association between Dukes stage and duration of patient history (Dukes stage C tumours were seen in 37% (CI: 26.2%-48.0%) of patients with a short symptomatic history as opposed to 34% (CI: 32%-62%) with a very long symptomatic history). Elective curative resection was not associated with a significantly different symptom duration than elective palliative resection (Palliative resections were performed in 24% (CI: 11.7%-36.4%) of patients with a short symptomatic history as opposed to 16% (CI: 2.4%-29.9%) with a very long symptomatic history). The median survival time for the four elective colorectal patient groups defined by length of symptomatic history was not significantly different , (short: n = 131, 4.3 years; medium: n = 136, 5.9 years; long: n = 136, 7.1 years; very long: n = 137, 5.0 years). Conclusion Tumour extent, completeness of resection and patient outcome after elective colorectal cancer resection was not found to have an association with length of patient history at the time of surgery.
