A mitochondrial antigen-antibody system in cholestatic liver disease detected by radioimmunoassay.

2007

A radioimmunoassay (RIA) was established for the detection of antimitochondrial autoantibodies (AMAs) in patient sera. AMAs were detected by RIA in 12 of 14 patients with primary biliary cirrhosis and in 3 of 29 patients with chronic active hepatitis. AMAs were detected by indirect immunofluorescence in all sera positive by RIA. In addition, two patients with primary biliary cirrhosis and one patient with chronic active hepatitis were AMA positive when tested by indirect immunofluorescence, but negative when tested by RIA. AMAs were not detected by RIA or indirect immunofluorescence in 121 further patients with various hepatic and nonhepatic diseases, including healthy controls. The RIA det…

The Multidimensional Inventory of Hypochondriacal Traits

2014

Severe health anxiety constitutes a disabling and costly clinical condition. The Multidimensional Inventory of Hypochondriacal Traits (MIHT) represents an innovative instrument that was developed according to cognitive-behavioral, cognitive-perceptual, interpersonal, and trait models of hypochondriasis. We aimed at evaluating the psychometric properties of the MIHT in a sample of patients with the Diagnostic and Statistical Manual of Mental Disorders (4th ed.) diagnosis of hypochondriasis. Using confirmatory factor analysis (CFA), the postulated four-factor structure of the MIHT was found in a first CFA in patients with hypochondriasis ( n = 178) and in a second CFA based on a mixed sample…

Implicit affective evaluation bias in hypochondriasis: findings from the Affect Misattribution Procedure.

2014

Cognitive theories of hypochondriasis (HYP) suggest that catastrophic misinterpretations of benign body sensations are a core feature for the maintenance of the disorder. There is tentative support from an analog sample that the interpretation of illness-related information also involves an implicit affective component. This is the first study to examine this negative affective evaluation bias implicitly in patients with HYP. An adapted version of the Affect Misattribution Procedure (AMP) with illness, symptom and neutral primes was used in 80 patients with HYP, and compared to 83 patients with an anxiety disorder (AD), as well as 90 healthy controls (CG). The HYP group showed significantly…

Oculopharyngeal muscular dystrophy in a northern German family linked to chromosome 14q, and presenting carnitine deficiency

1997

We report the evaluation of oculopharyngeal muscular dystrophy (OPMD) in a large northern German family, which can be traced back six generations and is unrelated to French-Canadian families. The symptoms in this family start at about 50 years of age and include dysphagia, bilateral ptosis, and in some cases a slowly progressive atrophy and weakness of other extraocular, facial or limb girdle muscles. The muscle biopsies showed the pathognomonic ultrastructural finding of characteristic intranuclear filaments. Linkage analysis confirmed that this family is also linked to chromosome 14q markers. Haplotype analysis revealed that a unique haplotype segregates with the disease which is differen…

Hypochondriasis, Somatoform Disorders, and Anxiety Disorders

2012

The question of whether hypochondriasis (HYP) should be considered a somatoform disorder (SFD) or classified as an anxiety disorder (ANX) has recently been raised. To empirically provide information on this issue, we compared patients with HYP (n = 65) with those with other SFDs (n = 94) and those with ANX (n = 224) regarding sociodemographic and biographical variables, general psychopathology, and naturalistic cognitive-behavioral therapy treatment effects. Compared with SFD, patients with HYP were younger and had fewer comorbid affective disorders and less impaired life domains, suggesting a closer connection between HYP and ANX. Regarding cognitive-behavioral therapy treatment effects, a…

Therapist competence and therapeutic alliance are important in the treatment of health anxiety (hypochondriasis)

2015

The role of treatment delivery factors (i.e., therapist adherence, therapist competence, and therapeutic alliance) is rarely investigated in psychotherapeutic treatment for health anxiety. This study aimed to investigate the role of the assessment perspective for the evaluation of treatment delivery factors and their relevance for treatment outcome. Therapist adherence, therapist competence, and therapeutic alliance were evaluated by independent raters, therapists, patients, and supervisors in 68 treatments. Patients with severe health anxiety (hypochondriasis) were treated with cognitive therapy or exposure therapy. Treatment outcome was assessed with a standardized interview by independen…

Extracellular matrix composition in COPD

2012

Extracellular matrix (ECM) composition has an important role in determining airway structure. We postulated that ECM lung composition of chronic obstructive pulmonary disease (COPD) patients differs from that observed in smoking and nonsmoking subjects without airflow obstruction. We determined the fractional areas of elastic fibres, type-I, -III and -IV collagen, versican, decorin, biglycan, lumican, fibronectin and tenascin in different compartments of the large and small airways and lung parenchyma in 26 COPD patients, 26 smokers without COPD and 16 nonsmoking control subjects. The fractional area of elastic fibres was higher in non-obstructed smokers than in COPD and nonsmoking controls…

Low testosterone levels are related to oxidative stress, mitochondrial dysfunction and altered subclinical atherosclerotic markers in type 2 diabetic…

2017

Abstract Introduction Low testosterone levels in men are associated with type 2 diabetes and cardiovascular risk. However, the role of testosterone in mitochondrial function and leukocyte-endothelium interactions is unknown. Our aim was to evaluate the relationship between testosterone levels, metabolic parameters, oxidative stress, mitochondrial function, inflammation and leukocyte-endothelium interactions in type 2 diabetic patients. Materials and methods The study was performed in 280 male type 2 diabetic patients and 50 control subjects. Anthropometric and metabolic parameters, testosterone levels, reactive oxygen species (ROS) production, mitochondrial membrane potential, TNFα, adhesio…

Rare sacral space-occupying lesions, their surgical management and reconstructive measures involved

1988

Nine cases of space-occupying lesions of the sacral bone are presented. The problems of the clinical diagnosis, which in many cases comes too late, are discussed together with the indications for surgical treatment in this special group of tumours. The main clues are provided by the changes in the X-rays as well as the more modern imaging techniques (CT and MRI). The surgical technique aims at a most radical tumour removal with preservation of the sacral nerve roots, after which stabilisation of the sometimes weakened pelvic girdle may be necessary. The good prospects of complete removal of these tumours of the sacrum with satisfactory results seem to be very little known and justifies furt…
