Explicit episodic memory for sensory-discriminative components of capsaicin-induced pain: immediate and delayed ratings.

Pain memory is thought to affect future pain sensitivity and thus contribute to clinical pain conditions. Systematic investigations of the human capacity to remember sensory features of experimental pain are sparse. In order to address long-term pain memory, nine healthy male volunteers received intradermal injections of three doses of capsaicin (0.

Cortical representation of experimental tooth pain in humans.

Cortical processing of electrically induced pain from the tooth pulp was studied in healthy volunteers with fMRI. In a first experiment, cortical representation of tooth pain was compared with that of painful mechanical stimulation to the hand. The contralateral S1 cortex was activated during painful mechanical stimulation of the hand, whereas tooth pain lead to bilateral activation of S1.

Detection of pooled secretions above endotracheal-tube cuffs: value of plain radiographs in sheep cadavers and patients.

Objective: Mechanical ventilation is thought to increase the risk of nosocomial pneumonia by permitting leakage of bacteria-laden gastro-oropharyngeal secretions into the upper airways. The goal of this study was (a) to validate radiographic signs of pooled secretions above endotracheal-tube cuffs (supracuff liquid) in an animal model and (b) to determine whether suctionable pooled supracuff liquid can be identified on bedside radiographs of intubated patients.

Materials And Methods: Diagnostic criteria for supracuff liquid were initially validated by three radiologists interpreting 162 randomized radiographs made in an intubated sheep cadaver.

[Drain fistulography. Radiological sphincter identification in high anal fistulae].

To warrant permanent surgical cure of high anal fistulae, while avoiding at the same time faecal incontinence due to inadvertent division of the puborectalis muscle, distinction between a trans- and suprasphincteric fistula track is essential. This differentiation is often crucial, since digital rectal palpation and conventional fistulography tend to be unreliable. Therefore we developed a radiological technique of imaging the anorectal fistulous track, "drain fistulography".

[X-ray measurement of the level of rectal carcinomas and its dependence on the functional status of the pelvic floor].

The influence of the various functional states of the pelvic floor on the radiological assessment of the tumour levels and the distant tumour-free distance in rectum neoplasms was investigated. The parameters "anal canal length", "anorectal angle" and "impression of the puborectalis muscle" were measured in lateral distant views of the rectum in a series of healthy controls (n = 160). In addition, these parameters and the "distant tumour-free distance" were measured in patients with rectal cancer (n = 40).
