Does Cytokeratin7/20 immunoreactivity help to distinguish Barrett's esophagus from gastric intestinal metaplasia? Results of a prospective study of 7…
2005
Barrett's esophagus is a recognized risk factor for the development of esophageal dysplasia and carcinoma. Unfortunately, gastric incomplete intestinal metaplasia arising in Short Segment Barrett's esophagus can be indistinguishable histologically on hematoxylin/eosin stains. Distinct patterns of CK 7 and CK 20 immunohistochemical expression have been demonstrated to be both highly sensitive and specific for Barrett's esophagus, but have not been found in gastric metaplasia. The aim of our study was to test whether immunostaining with CK 7/20 helps to distinguish between Barrett's epithelium and gastric incomplete metaplasia. Cases of long segment Barrett's esophagus, short segment Barrett'…
The cheating liver: imaging of focal steatosis and fatty sparing
2016
ABSTRACT: Focal steatosis and fatty sparing are a frequent finding in liver imaging, and can mimic solid lesions. Liver regional variations in the degree of fat accumulation can be related to vascular anomalies, metabolic disorders, use of certain drugs or coexistence of hepatic masses. CT and MRI are the modalities of choice for the noninvasive diagnosis of hepatic steatosis. Knowledge of CT and MRI appearance of focal steatosis and fatty sparing is crucial for an accurate diagnosis, and to rule-out other pathologic processes. This paper will review the CT and MRI techniques for the diagnosis of hepatic steatosis and the CT and MRI features of common and uncommon causes of focal steatosis …
Comparison of anti-transglutaminase ELISAs and an anti-endomysial antibody assay in the diagnosis of celiac disease: A prospective study
2002
Abstract Background: Most studies of anti-transglutaminase (anti-tTG) assays have considered preselected groups of patients. This study compared the sensitivity, specificity, and predictive value of an immunofluorescence method for anti-endomysial antibodies (EmAs) and two anti-tTG ELISAs, one using guinea pig tTG (gp-tTG) and the other human tTG (h-tTG) as antigen, in consecutive patients investigated for suspected celiac disease (CD). Methods: We studied 207 consecutive patients (99 men, 108 women; age range, 17–84 years) who underwent intestinal biopsy for suspected CD. Patients presented with one or more of the following: weight loss, anemia, chronic diarrhea, abdominal pain, dyspepsia,…
Long-term outcomes of short-term and long-term psychosomatic inpatient treatment and their predictors
2007
Abstract Objectives The Clinic for Psychosomatic Medicine and Psychotherapy at the University Giessen, Germany, offers short-term (STT) and long-term inpatient therapy (LTT). Methods In a prospective, 3-year follow-up study, we examined therapeutic indication, short- and long-term results, outcome predictors, and the utilization of aftercare for both settings. Results STT patients were more frequently acutely ill, suffered from stronger symptomatic manifestations, and were more frequently employed. LTT patients had a greater rate of chronic psychosomatic disorders, personality disorders and somatic comorbidity. In both settings, distress strongly declined during inpatient therapy and remain…
Spontaneous echo contrast imaging in infective endocarditis: a predictor of complications?
1992
Infective endocarditis is associated with significant morbidity and mortality. Valvular destruction and congestive heart failure are more common in patients with echocardiographically detectable vegetations. In addition, spontaneous platelet aggregation is increased when vegetations are present on cardiac valves. The aim of the study was to assess the prognostic value of spontaneous echo contrast (SEC) imaging, as SEC is supposed to reflect red blood cell aggregates stimulated by platelet activity. We studied 293 patients with clinical signs of infective endocarditis. Vegetations, attached to the aortic or mitral valve, were found in 130 patients (44.4%) who were followed for a mean period …
Association of MR-proadrenomedullin with cardiovascular risk factors and subclinical cardiovascular disease.
2012
Abstract Aims and background Midregional proadrenomedullin (MR-proADM) is a protein, which exerts various effects on the cardiovascular system. Recent studies underscored its prognostic implications in patients with acute dyspnea and cardiovascular diseases. Therefore, we aimed to determine the distribution of MR-proADM in the general population and to reveal potential associations of MR-proADM with cardiovascular risk factors and measures of subclinical cardiovascular disease. Methods and results MR-proADM plasma concentrations were determined in individuals of the population-based cohort of the Gutenberg Health Study ( N = 5000) using a commercially available fluoroimmunoassay. Individua…
Hyperuricemia in acute heart failure. More than a simple spectator?
2007
Hyperuricemia is a prevalent condition in chronic heart failure (CHF), describing increased oxidative stress and inflammation. Although there is evidence that serum uric acid (UA) predicts mortality in CHF, its role as a prognostic biomarker in acute heart failure (AHF) has not yet been well assessed. The aim of this study was to determine if UA levels predict all-cause mortality. Additionally, as a secondary endpoint we sought the clinical predictors of UA serum level in this population.We analyzed 560 consecutive patients with AHF admitted in a single university center. UA (mg/dl) was measured during early hospitalization. Patient survival status was followed up after discharge (median fo…
Predicted and actual fetal weight throughout the last trimester.
1997
The aim of our study was to obtain, in normal pregnancies, references values of predicted and actual fetal weight for both male and female fetuses and for fetuses born to nulliparous and multiparous women between weeks 28 and 41 of gestation. Predicted fetal weight curves represented calculations of weight in the third trimester based on weight data obtained during the second trimester. These curves were obtained from 134 ultrasonograms obtained between weeks 20 and 27. Actual fetal weight curves represented the values calculated from third trimester measurements and were based on 374 ultrasonograms obtained between weeks 28 and 41. For predicted fetal weight minor differences were found be…
Quality of Life in Individuals Affected by Arnold Chiari Malformation: Comparison and Validation of a Measurement Instrument.
2017
BACKGROUND Introduction. Arnold Chiari Malformation (ACM) type I is a pathology whose symptomatology has repercussions for the quality of life of those affected by it. Quality-of-life measurement instruments can allow the severity of the impact of Chiari type I malformation on patients' lives to be monitored. The Chiari Symptom Profile (CSP) is a valid and reliable instrument designed for this purpose. The aim of the study was to adapt the CSP to Spanish and to explore the reliability and validity of this construct in the context of Spanish-speaking patients with ACM. METHODS The English CSP instrument has a good internal validity and consistency. We used a standardized procedure for the li…
Utility of the PHQ-9 to identify major depressive disorder in adult patients in Spanish primary care centres.
2017
Abstract Background The prevalence of major depressive disorder (MDD) in Spanish primary care (PC) centres is high. However, MDD is frequently underdiagnosed and consequently only some patients receive the appropriate treatment. The present study aims to determine the utility of the Patient Health Questionnaire-9 (PHQ-9) to identify MDD in a subset of PC patients participating in the large PsicAP study. Methods A total of 178 patients completed the full PHQ test, including the depression module (PHQ-9). Also, a Spanish version of the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) was implemented by clinical psychologists that were blinded to the PHQ-9 results. We evaluat…
