"Sniffin' Sticks" is a new test of nasal chemosensory performance based on pen-like odour-dispensing devices. This portable test is suited for repetitive, inexpensive screening of odour identification. The test includes a forced odour-identification task for seven odours performed by means of a list of four items (multiple-choice). In 146 subjects the basic(More)
Healthy controls were compared to patients with decreased olfactory sensitivity (n = 32) to investigate interactions between the olfactory and trigeminal systems. Amplitudes of chemo-somatosensory event-related potentials in response to suprathreshold trigeminal stimuli (CO2) were found to be smaller in patients (P < 0.05) indicating a decrease of(More)
The properties of a newly developed tonic heat pain model (THPM), which makes use of pulsating contact heat, were investigated in 18 young men. The most important feature of this model is that repetitive heat pulses with an intensity of 1 degree C above the individual pain threshold are employed. This approach was used to tailor the tonic pain stimulation(More)
A decrease in pain sensitivity during acute depression has been observed in several studies, apparently related to the severity of symptomatology. However, the question remains whether this relationship can be found only in heterogeneous groups of depressive patients or also in a single diagnostic group, such as major depression. In the present study, pain(More)
Multiple chemical sensitivities (MCS) has become an increasingly frequent diagnosis assigned to patients with symptoms associated with exposures to environmental chemicals. Since the characteristic symptoms of MCS are triggered by very low concentrations of chemicals, in the range of olfactory thresholds, it is widely believed that the intranasal(More)
Heterotopic noxious conditioning stimulation (HNCS) has been thought to give access to the diffuse noxious inhibitory controls (DNIC) in man, which can be activated in wide-dynamic-range neurons by noxious stimulation from remote areas of the body and form the neurophysiological basis of the phenomenon 'pain inhibits pain'. The latter phenomenon suggests(More)
OBJECTIVE The aim of this study was to investigate the influence of odorant concentration on the olfactory event-related potential (OERP). METHODS OERP were evaluated in 8 men and 8 women (17-34 years of age) in response to 4 concentrations of vanillin (7, 28, 56 and 84% v/v). Sixteen presentations of each concentration (stimulus duration 200 ms, interval(More)
The antinociceptive potency of corticotropin-releasing-hormone (CRH) has been established in several animal studies in which both central and peripheral sites of action were considered. However, there have not yet been any experimental trials, besides one attempt using clinical dental pain demonstrating the potential analgesic properties of CRH in humans.(More)
BACKGROUND During the last few years, risk assessment has become one of the main topics of periodontal research. Therefore, the aim of this study was to determine whether a predisposition to metabolic disorders such as diabetes mellitus (in the absence of diagnosed diabetic disease) or hyperlipidemia may be risk indicators for periodontitis. METHODS One(More)
In 21 restrained and 20 unrestrained eaters body size perception was measured using the video distortion technique (VDT), the image marking procedure (IMP) and the kinesthetic size estimating apparatus (KSEA). Body satisfaction was assessed by questionnaires (Body Shape Questionnaire, Dieting scale of the Eating Attitudes Test). Restrained eaters showed no(More)
