Phantom limb sensations in adolescents: a case study to illustrate the utility of sensation and pain logs in pediatric clinical practice.

Although the nature of pain following amputations has been well documented for adults, little research has been conducted to determine the incidence, prevalence, and nature of phantom limb sensations and pains in children and adolescents. This case study documents the nature of phantom limb sensation (intensity, quality, location, duration, and frequency) for a 15-yr-old adolescent after leg amputation. She completed a brief sensation/pain log, consisting of quantitative and qualitative scales, for 28 days after surgery. She experienced phantom limb sensations, which spread from her toes to encompass her entire leg by day 10 after surgery. The pattern of spread was not consistent throughout this period. The quality of sensations remained relatively constant and was described as itching and tingling. The phantom sensations were not experienced consistently throughout the day, but were experienced as discreet episodes. Both the duration and frequency of these episodes decreased throughout the 28 days. Similarly, the intensity of her phantom sensations decreased gradually throughout this period. This case study illustrates how it is possible to integrate research with health care delivery in a practical manner, to obtain prospective information about the nature of childhood sensory experiences.

[Preliminary observation on the relation among needling sensation, propagated sensation along meridian (PSM), and acupuncture effect when acupuncture neiguan].

This paper reports 300 coronary heart disease patients with different needling sensations, mainly with distension, when acupuncturing Neiguan by identical acupuncture doctor with same manipulation. The higher rate of PSM appearance and better acupuncture effect were observed, in patients with compound sensation, such as sourness-distension and distension-numbness. All of the patients who felt pain did not appear PSM and the acupuncture effect was poor. The appearance rate of PSM and acupuncture effect of other kind needling sensations were between the two. The results showed the kind of needling sensation while acupuncture had close relation with the appearance of PSM and the acupuncture effect.

The sensation seeker and anxiety reactivity: relationships between the sensation-seeking scales and the activity preference questionnaire.

The five scales of the Zuckerman Sensation-Seeking Scale and Lykken's Activity Preference Questionnaire were administered to 83 male and female college students to test the hypothesis that there is an inverse relationship between sensation seeking and anxiety reactivity. The data were intercorrelated separately for males and females. Results were, in general, consistent with expectations: individuals high in optimal level of stimulation are low in anxiety reactivity in situations that involve physical danger and in situations related to social fears or embarrassment. This relationship was found for most of the dimensions of sensation seeking for males, but was confined to specific subscales for females.

Testing for and the role of anal and rectal sensation.

The rectum is insensitive to stimuli capable of causing pain and other sensations when applied to a somatic cutaneous surface. It is, however, sensitive to distension by an experimental balloon introduced through the anus, though it is not known whether it is the stretching or reflex contraction of the gut wall, or the distortion of the mesentery and adjacent structures which induces the sensation. No specific sensory receptors are seen on careful histological examination of the rectum in humans. However, myelinated and non-myelinated nerve fibres are seen adjacent to the rectal mucosa, but no intraepithelial fibres arise from these. The sensation of rectal distension travels with the parasympathetic system to S2, S3 and S4. The two main methods for quantifying rectal sensation are rectal balloon distension and mucosal electrosensitivity. The balloon is progressively distended until particular sensations are perceived by the patient. The volumes at which these sensations are perceived are recorded. Three sensory thresholds are usually defined: constant sensation of fullness, urge to defecate, and maximum tolerated volume. The modalities of anal sensation can be precisely defined. Touch, pain and temperature sensation exist in normal subjects. There is profuse innervation of the anal canal with a variety of specialized sensory nerve endings: Meissner's corpuscles which record touch sensation, Krause end-bulbs which respond to thermal stimuli, Golgi-Mazzoni bodies and pacinian corpuscles which respond to changes in tension and pressure, and genital corpuscles which respond to friction. In addition, there are large diameter free nerve endings within the epithelium. The nerve pathway for anal canal sensation is via the inferior haemorrhoidal branches of the pudendal nerve to the sacral roots of S2, S3 and S4. Anal sensation may be quantitatively measured in response to electrical stimulation. The technique involves the use of a specialized constant current generator and bipolar electrode probe inserted in the anal canal. The equipment is generally available and the technique has been shown to be an accurate and repeatable quantitative test of anal sensation.

[Sensation seeking and mood dimensions in depressive states].

This study presents the investigation of the relations between dimensions of depressive mood and sensations seeking in 55 hospitalized depressed subjects. The concept of sensation seeking, identified by M. Zuckerman as a personality dimension, has been defined as the need for the subject to reach his optimal level of activation. The four subscores of sensation seeking, relatively independent, are identified in the sensation seeking scale; they stand at different levels on the dimensions of activation and pleasure which are emotional dimensions. These emotional dimensions are investigated in the exploration of the emotional components of depressive mood; the different symptomatic regroupings, such as blunted affect or impulsivity, do not have the same relations with these dimensions. The sensation seeking concept appears fruitful to investigate the different troubles of affective dynamic, which stand on the expressive and behavioral level, and on the subjective level. As in several studies with normal populations, we find again the same inverse relation between age and sensation seeking, and men obtain higher scores on the Thrill and Adventure seeking factor and on the Desinhibition factor. Globally, depressed subjects have lower scores of sensation seeking than normal subjects (paired by age and sex); but the weakness of sensation seeking is not proportional to the intensity of depression (Hamilton Depressive Scale) and to the the intensity of anxiety (Covi Brief Anxiety Scale). Interesting relations appear with the depressive mood factors, which agree with previous studies of sensation seeking in psychology and psychopathology.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical vs quantitative evaluation of cutaneous sensation.

A comparison of the evaluation of cutaneous sensation by neurologic examination and by quantitative assessment in 107 patients with various neuromuscular disease has shown that there is a reasonably good correlation between the recognition of abnormalities of cutaneous sensation by clinical and by quantitative methods. Clinical neurologists tend to underestimate abnormalities of touch-pressure sensation. The quantitative evaluation of cutaneous sensation is useful in quality control of the clinical examination, in correlating the nature of sensation loss with the compound action potential and morphometry of biopsied nerve, in providing a score of sensation to follow the course and the effect of treatment protocols, and in monitoring for an adverse effect on sensation by an environmental or industrial poison. There is a good correlation between abnormality of touch-pressure sensation and loss of large myelinated fibers of sural nerve in neuropathy.

Effects of preparatory information about sensations, threat of pain, and attention on cold pressor distress.

Pain experience is conceptualized as a combination of stimulus sensations (e.g., aching) and emotional distress. In Experiment 1, less distress was reported to cold pressor stimulation by subjects first told about stimulus sensations than by subjects who were uninformed or were told about symptoms of bodily arousal (e.g., tension). Adding a pain warning to sensation information blocked distress reduction, presumably by eliciting an emotional interpretation of the stimulus. In Experiment 2, subjects attending only to hand sensations reported less distress than subjects attending to their bodies. This decrease in the power of the stimulus to provoke emotion is presumably mediated by a schema of hand sensations formed by attention. In Experiment 3, subjects attending to hand sensations early in the immersion and distracting themselves later reported the same low levels of distress as did subjects who attended to hand sensations throughout. Subjects distracted throughout and subjects attending to hand sensations later showed no distress reduction. Therefore, stimulus schematization must precede distress reduction. Implications for distress control are discussed.

Sensation evoked by bipolar intrapulpal stimulation in man.

Bipolar intrapulpal stimulation was applied to human teeth using the same procedure as in animal experiments. The effects of variation of stimulus parameters on the quality of sensation were studied. A prepain sensation exists which cannot be explained by diffusion of the stimulus to periodontal tissues. When the intensity of stimulation is increased, the prepain sensation is gradually replaced by a pinprick sensation. With long, high intensity stimulation, an acute long lasting very painful sensation appears. To evoke a pinprick sensation the best stimulation seems to be a 50 msec train (0.5 msec, 300 Hz, 0.5 mA). Longer train duration and a higher intensity of current are necessary to evoke a long lasting, acute very painful sensation. Since the exclusively Adelta and C nerve fiber content of the dental pulp is well documented and since it is possible to avoid current diffusion outside the dental pulp cavity, the tooth pulp implantation seems to be a good technic for studying pain, as long as the investigator uses adequate stimulation.

[Dyspnea sensation during resistive loading].

To examine the relationship among the sensation of dyspnea, the respiratory muscle oxygen consumption (VO2 resp), minute ventilation and occlusion pressure, seven normal volunteers were studied during incremental dead space loading induced hyperventilation with and without inspiratory resistive load. Although the sensation of dyspnea and VO2 resp at the same level of minute ventilation increased with an increase in resistance, there appeared to be a unique relationship among the sensation of dyspnea, VO2 resp and occlusion pressure, which was not affected by inspiratory resistive loading from 0 to 20 cmH2O/l/sec. These results show that the ventilatory command signal is closely related to the dyspnea sensation. We also found that during incremental dead space loading the quality of the sensation changed relatively quickly at some point, where tidal volume was maximum with each resistive loading and the breathing pattern changed. In the other experiment, the functional residual capacity (FRC) decreased during inspiratory resistive and elastic loading. Because the decreased FRC was associated with the decrease in the dyspnea sensation, it was speculated that the subject decreased his FRC through a cortical response so that the sensation of dyspnea during loading decreased.

Temporary threshold shift of temperature sensation caused by vibration exposure.

The temporary threshold shift of temperature sensation due to vibration exposure was studied to clarify the significance of frequency and acceleration on it. The discrete frequencies of the vibrations tested were 32, 63, 125, 250 and 500 Hz, and the accelerations were at the level of 2, 4, 8 and 16 g. The threshold shift of warm sensation (TTSw) was markedly, but that of cool sensation was small and not significantly different from the control value. TTSw increased with a rise in the level of acceleration and was largest at 125 Hz among the frequencies examined. The most effective frequency among the vibrations tested for warm sensation was inferred to be lower than that for vibratory sensation. After exposure, TTSw or the increment of the neutral zone decayed exponentially but bounced slightly in the later period. These patterns of TTSw are similar to those of the vibration-induced TTS of vibratory sensation.

Sensation seeking and selective attention: focused and divided attention on a dichotic listening task.

Differences in selective attention as a function of sensation seeking, extraversion, neuroticism, and psychoticism were examined in 108 undergraduates using a dichotic listening task. Dependent measures included shadowing performance, reaction times to a secondary light task, target detection, and recall. The results suggested that high sensation seekers have better focused attention than low sensation seekers, and these effects were strongest on the 1st trials of the shadowing tasks. High sensation seekers did not attend differently than low sensation seekers to words related to their interests (sexual, violent, or drug related). Extraversion was associated with greater recall of these kinds of words, although there were no overall differences in selective attention as a function of Eysenck's dimensions. The role of arousal in personality and attention is discussed, particularly in regard to the response of sensation seekers to task novelty.

Altered sensation following mandibular implant surgery: a retrospective study.

To determine the prevalence of complications involving altered sensation after implant surgery in the mandible, a retrospective questionnaire study was conducted of 266 patients treated with osseointegrated implants. Of the responding patients (80%), 37% reported altered sensation following implant surgery, with long-term changes occurring in 13% of patients. In more than 60% of symptomatic patients the onset was within 1 week of the first stage of surgery and most frequently involved the lip and chin. Resolution of transient changes usually occurred within 6 months and the majority of patients who reported alterations in sensation believed that the benefits of the implant surgery outweighed the disadvantages experienced. The prevalence of altered sensation was significantly higher in women compared with men and in those with a history of diabetes. These data indicate the need for prospective studies to further evaluate altered sensation after mandibular implant surgery so that specific risk factors can be identified and more accurate information made available to prospective patients.

Prostaglandin E2 inhalation increases the sensation of dyspnea during exercise.

To clarify the role of vagal afferents from the lung in the sensation of dyspnea, we examined the effects of prostaglandin E2 (PGE2) inhalation on the sensation of dyspnea during exercise in eight normal male subjects. This intervention was chosen because inhaled PGE2 is known to stimulate vagal afferent receptors in the lung, in particular C-fiber endings, without a significant increase in airway resistance. After either physiologic saline or PGE2 aerosol (100 micrograms/ml) inhalation through a Bird nebulizer for 2 min, exercise tests were performed on a bicycle ergometer. The tests consisted of 3 min at rest followed by graded work loads (zero to 150 watts, 50-watt increments). Minute ventilation (VE) and respiratory rate were monitored from an expiratory line through a face mask. Oxygen consumption (VO2) and carbon dioxide production (VCO2) were calculated from samples of mixed expired gas. The sensation of difficulty in breathing (dyspnea) was measured on a modified Borg scale at rest and at the end of each work load. We found that although airway resistance and lung volume did not change significantly between saline and PGE2 inhalations, inhaled PGE2 significantly increased the magnitude of the dyspneic sensation when compared with inhaled saline at the same levels of work load, ventilation, and oxygen consumption. These results suggest that in addition to probable roles of motor command and chemical drive, afferent vagal activity from the lung also contributes to the sensation of dyspnea during exercise.
