Sleep investigations in erectile dysfunction
2003
Abstract Regarding the aetiology of erectile dysfunction, beside numerous organic causes in many cases psychological factors play an important role. The pathophysiological mechanisms underlying the so-called psychogenic erectile dysfunction are not yet understood. Based on a neurobiological approach to psychogenic erectile dysfunction, polysomnographic investigations were carried out with the aim of identifying possible alterations of the sleep EEG. 24 male patients with psychogenic erectile dysfunction without detectable organic factors or other mental disorders were studied in the sleep laboratory, as well as an age-matched control group without sexual dysfunctions. Beside a reduction of …
Relationship between Patient Discomfort, Appliance Acceptance and Compliance in Orthodontic Therapy
2000
Orthodontic treatment is occasionally a discomfort to patients, due to pain or functional restrictions. In this context, several retrospectively planned studies were performed in the 1980s, but correlations between different aspects of patient discomfort were not investigated. The present study aimed at examining and structuring the psychogenic dimensions of patient discomfort. Furthermore, the impact of the patient's attitude on the intensity of discomfort was to be evaluated in addition to the influences of appliance therapy. The study was performed with 67 patients aged from 9 to 32 years. Prior to insertion of a new appliance, psychogenic scales reflecting their attitude towards orthodo…
Effects of moclobemide on sexual performance and nocturnal erections in psychogenic erectile dysfunction
2001
Rationale and objectives: We tested the hypothesis that the selective reversible MAO-A inhibitor moclobemide has a specific therapeutic effect on erectile dysfunction independent of its antidepressive properties. Methods: In a double-blind placebo controlled study, 12 male outpatients suffering from psychogenic erectile dysfunction without any other psychiatric disorder were investigated. Based on comprehensive diagnosis before the beginning of the study, organic factors relevant for sexual function were excluded. The treatment period was 8 weeks. Half the patients received 450 mg moclobemide during the first week, and 600 mg afterwards; the others received placebo. Apart from assessment of…
Cingulo-Insular Structural Alterations Associated with Psychogenic Symptoms, Childhood Abuse and PTSD in Functional Neurological Disorders
2017
Objective Adverse early-life events are predisposing factors for functional neurological disorder (FND) and post-traumatic stress disorder (PTSD). Cingulo-insular regions are implicated in the biology of both conditions and are sites of stress-mediated neuroplasticity. We hypothesised that functional neurological symptoms and the magnitude of childhood abuse would be associated with overlapping anterior cingulate cortex (ACC) and insular volumetric reductions, and that FND and PTSD symptoms would map onto distinct cingulo-insular areas. Methods This within-group voxel-based morphometry study probes volumetric associations with self-report measures of functional neurological symptoms, advers…
The concept of major depression. III. Concurrent validity of six competing operational definitions for the clinical ICD-9 diagnosis.
1991
The comparative validity of six operational diagnoses of major depression was evaluated in 600 psychiatric inpatients using the independently assessed clinical ICD-9 diagnoses as a yardstick. Agreement with, and positive predictive value for the ICD-9 categories of pure (endogenous and psychogenic) depression served as validation criteria; sensitivity of major depression diagnoses for detecting ICD-9 bipolar depressions was additionally used for examining the adequacy of width, time and exclusion criteria of the competing operational definitions. Three essential results were found. First, the "old" diagnostic definitions of RDC and FDC are superior to all newer definitions because they defi…
Orofacial pain of cardiac origin: review literature and clinical cases
2012
The most common types of orofacial pain originate at the dental or periodontal level or in the musculoskeletal structures. However, the patient may present pain in this region even though the source is located elsewhere in the body. One possible source of heterotopic pain is of cardiac origin. Objectives: Report two cases of orofacial pain of cardiac origin and review the clinical cases described in the literature. Study Design: Description of clinical cases and review of clinical cases. Results and conclusions: Nine cases of atypical pain of cardiac origin are recorded, which include 5 females and 4 males. In craniofacial structures, pain of cardiac origin is usually bilateral. At the cran…
Psychogenic nonepileptic seizures in pediatric population: A review
2019
Abstract Introduction Psychogenic nonepileptic seizures (PNES) are observable abrupt paroxysmal changes in behavior or consciousness that resemble epileptic seizures, but without concurrent electroencephalographic abnormalities. Methods In this manuscript, we reviewed literature concerning pediatric PNES and focused on those articles published in the last 10 years, in order to try to understand what the state of the art is at the moment, particularly as regards relationship and differential diagnosis with epilepsy. Results Psychogenic nonepileptic seizures have been extensively described in literature mainly in adults and less frequently in children. Despite the potential negative impact of…
Persistent psychogenic déjà vu: a case report.
2014
Introduction: Déjà vu is typically a transient mental state in which a novel experience feels highly familiar. Although extensively studied in relation to temporal lobe epilepsy as part of simple partial seizures, déjà vu has been less studied in other clinical populations. A recent review of temporal lobe epilepsy suggested a possible link between clinical levels of anxiety and debilitating déjà vu, indicating further research is required. Here, for the first time in the literature, we present a case study of a young man with anxiety and depersonalisation who reported experiencing persistent and debilitating déjà vu. This report therefore adds to the limited literature on the relationship …
Can loss of sensory attenuation be accurately demonstrated using two effectors simultaneously?
2015
Sir, Recently, Parees and colleagues (2014) compared patients with functional (psychogenic) movement disorders and healthy subjects who were asked to match a force delivered to their left finger by pressing on it directly, or by operating a joystick to press down on it, with the other hand. They observed that healthy subjects generated more force than required when pressing directly on their finger (compared with using the joystick), whereas patients did not. They interpreted and discussed this result as a loss of sensory attenuation that typically occurs in healthy subjects during self-generated movements and suggested by return, that it illustrates an altered sense of agency for the patie…
Anxiety disorders and other psychiatric subgroups in patients complaining of dizziness.
2003
Two hundred and two consecutive patients with dizziness were evaluated using blind neuro-otological testing and examination, blind psychiatric examination, including structured interviews (according to DSM-IV), the Symptom Check-List (SCL 90 R), and the State-Trait Anxiety Inventory (STAI). In 28% of the patients (N=50) dizziness was of organic origin (O group); in 55.3% (N=99) of psychogenic origin (P group) and in 16.8% comorbid psychiatric disorders were found (Mixed group). In 5.3% (N=10) neither organic nor psychiatric results could be found, which could explain the dizziness (Ideopathic group). Compared with the Organic group the patients with psychiatric disorders (P and Mixed group)…
