This study has collated data on the prevalence of chronic wounds and the demography of patients with these wounds. Diagnostic methods, nursing care, the presence of diabetes and pain are analysed, as well as data on healing, amputation and mortality three months post-study. A total of 694 patients were identified: 406 with leg or foot ulcers, 117 with pressure ulcers and 171 with other wounds. Most patients were treated in the community. Leg ulcer aetiology was verified with ultrasound Doppler examination. There was a correlation between low Norton score (< 20) and severity of pressure ulcer (Stage III or IV). The use of 113 different wound dressings or combinations of products was reported. Time spent on dressing changes was the equivalent of full-time employment for 57 nurses. Wound cleansing was not predominantly performed with tap water, as recommended, but with saline. Almost all patients with venous leg ulcers (88%) were treated with compression but in 35% of these support stockings were used. Pain was present in almost half of all patients, more commonly in Stage III or IV pressure ulcers than in Stages I and II, and was most often reported in older patients. Diabetes was present in 25% of all patients with leg and pressure ulcers, and in 57% of patients with foot ulcers. At three-month follow-up, 28% of pressure ulcers, 40% of leg ulcers and 61% of other wounds had healed. Mortality was 35% in patients with pressure ulcers, 4% in those with leg ulcers and 7% in those with foot ulcers. These data have been presented to politicians in the county, resulting in allocation of resources for a wound healing centre.

The Chronic Pain Coping Inventory (CPCI; Jensen, M.P., Turner, J.A., Romano, J.M. and Strom, S.E., The Chronic Pain Coping Inventory: development and preliminary validation, Pain, 60 (1995) 203-216) is a recently developed questionnaire comprising eight main subscales that measure coping strategies that are frequently targeted for change in interdisciplinary pain treatment programs. Preliminary research, carried out by the developers of the CPCI, supports the reliability and validity of the scale. The purpose of the present study was to further examine the validity of the CPCI independently. In the present study, 210 patients were administered the CPCI, along with the Coping Strategies Questionnaire (CSQ; Rosenstiel, A.K. and Keefe, F.J., The use of coping strategies in low back pain patients: relationship to patient characteristics and current adjustment, Pain, 17 (1983) 33-44; Riley III, J.L. and Robinson, M.E., CSQ: five factors or fiction? Clin. J. Pain, 13 (1997) 156-162), and the Multidimensional Pain Inventory (MPI; Kerns, R.D., Turk, D.C. and Rudy, T.E.. The West Haven-Yale Multidimensional Pain Inventory (WHYMPI), Pain, 23 (1985) 345-356) as part of a pre-admission screening. Principal components analysis with oblique rotation was performed on the 64 main CPCI scale items. An eight-factor solution was identified as most appropriate. The original subscales were generally supported, however, some modifications to scoring of subscales were suggested. As a second step in the study, the relationship between the modified CPCI subscales and the CSQ subscales were examined and their relative ability to predict concurrent adjustment to pain (MPI subscales) was assessed. Results indicated that CPCI subscales tap coping constructs that are conceptually different than the CSQ subscales. Several CPCI subscales were also found to be significantly and uniquely related to measures of concurrent adjustment, even after taking CSQ subscales and demographic and pain-related variables into account. These results suggest the CPCI is a valuable tool, above and beyond established coping measures, in the clinical assessment and research of pain. Directions for future research are discussed.

We encountered two cases of Pasteurella multocida subsp. septica isolation from exudates with seminal fluid-like odor from dog scratch and cat bite. Case 1: A 78-year-old male who had been diagnosed as having diabetes mellitus five years ago was scratched by the claw of a pet dog (Pekinese) on the back of the right hand. Since inflammation ascended to the arm, the patient visited Nihon University Itabashi hospital for a medical examination. Case 2: A 51-year-old female without a specific past history other than hyperlipidemia was bitten by a pet cat at the medical and lateral sides of the left carpus. The patient immediately opened the wound and washed it with tap water, followed by disinfection using a non-iodine disinfectant at home. Two hours later, the patient felt an unpleasant sensation and smelled a seminal fluid-like odor at the wound. The next morning, the entire left arm swelled and pain worsened, then the patient sought medical attention. The patients were treated with antibiotics and the wound completely healed on the 16 days from on set in Case 1 and on the 10 days from onset in Case 2. From these two cases, Pasteurella multocida subsp. septica was isolated from the exudate, suggesting that when wounds caused by animals smell like seminal fluid, the wound is infected with Pasteurellae. This finding may be an important clue for differentiation in clinical diagnosis.

In the present human study, we aimed to investigate the facilitation of both the subjective pain responses, and the withdrawal reflex to consecutive transcutaneous electrical stimuli as measures of temporal summation. The frequency (0.5-20 Hz) and intensity (0.4-0.8 times the reflex threshold, xRT) of the electrical stimuli were systematically varied. When using repeated stimulation, the stimulus intensity that evoked pain was lower than that required by a single stimulus (temporal summation). Temporal summation leading to pain was found to depend significantly upon both frequency and intensity (e.g. stimulation at 1 Hz caused summation at 0.8 x RT, whereas stimulation at 20 Hz caused summation at 0.6 x RT). The strongest reflex facilitation, and hence the strongest pain intensity was obtained for stimulation at 10-20 Hz at an intensity of 0.8 x RT. In conclusion, the results of the present human study demonstrate clearly that a stimulus that is perceived as a localised, repetitive tactile tap can be integrated and cause severe pain. This suggests that pathologically generated sparse nociceptive afferent activity causes strong pain by central integration. This might be one mechanism to explain why clinical conditions can become excruciatingly painful despite the fact that the pathophysiological changes seem to be marginal (e.g. minor nerve trauma).

Successive inhibitory, excitatory, inhibitory and excitatory reflexes (the Q, R, S and T waves of the post-stimulus electromyographic complex (PSEC)), evoked by applying non-painful taps to an incisor tooth, were recorded from the jaw-closing muscles of 15 subjects. The effects on these reflexes of the subjects undertaking mental exercises (MEx) in the form of arithmetic calculations were compared with those of remote noxious stimulation (RNS; application of 3 degrees C to a hand). This was done to investigate whether the previously established effects of RNS were likely to be related to a change in the subject's mental state and/or to direct nociceptive mechanisms. Both MEx and RNS caused increases in EMG activity around the Q-R and S-T transitions of the PSEC, which resulted principally from shortenings of the inhibitory Q and S waves. Reducing the intensity of the tap stimuli, which mimicked condition-induced disinhibition, caused shortenings of the inhibitory waves at latencies similar to the shortenings induced by MEx or RNS. The magnitude of the RNS-induced effect on the ST segment of the PSEC was greater (P<0.01) than that on the QR segment. By contrast, MEx induced similar effects on both segments. Regression analyses were performed for the relationship between condition-induced changes in amplitude of the excitatory waves and their control amplitudes. These analyses were performed to reveal any condition-induced inhibition or facilitation of the tap-induced influences on the motoneurons. Overall, the evidence suggested that: (1) mental exercise induced a similar degree of inhibition of the two tap-induced inhibitory jaw reflexes and a facilitation of the excitatory ones, and (2) remote noxious stimulation induced an inhibition of the second tap-induced inhibitory reflex which was greater than that of the first one, and an inhibition of the first excitatory reflex. Thus, although factors related to altered mental activity could play a role in the modulation of jaw reflexes by RNS, the differences between the effects of MEx and RNS suggest that alternative or complementary mechanisms are also likely to be involved.

Using the database of our pain management team, we examined the records of 254 patients weighing between 4.5 kg and 10 kg who received an epidural for postoperative analgesia. We looked at the incidence of catheter related problems in two groups of patients in whom either a 21-G (18-G short Tuohy needle) or a 23-G catheter (19-G short Tuohy needle) was used. There was a significantly higher incidence of difficulty in threading the catheter, kinking and occlusion in the 23-G catheter group. There were more leaks in the 21-G catheter group but the difference was not significant and both groups had a comparable incidence of clinically relevant leakages. No dural tap or difficulty in using either needle were reported.

The subcortical integrative effects of laser-induced activation of pain ascending tracts were examined in 11 healthy volunteers, aged 22-52 years. Subjects underwent either CO2 laser stimulation at the dorsum of the hand, electrical stimulation of digital nerves at the 3rd finger, or mechanical taps to the first dorsal interosseous space, preceding a blink reflex elicited by a supraorbital nerve electrical stimulus. The percentage inhibition induced in the R2 response of the blink reflex was similar for the three different stimulus modalities, but occurred at a different time interval. Compared to control trials, the R2 response of the test trials was a mean of 23.1% at the interval of 250 ms with laser stimuli, 17.4% at the interval of 100 ms with electrical stimuli to the 3rd finger, and 20.6% at the interval of 90 ms with a mechanical tap to the 1st interosseous space. Activation of pain receptors induces prepulse inhibition of the blink reflex at a delay corresponding to a slowly conducting pathway. The percentage inhibition is similar to that observed with other somatosensory inputs.

Epidural analgesia is the most effective and innocuous technique for obstetrics. Pain relief is its main indication but maternal diseases that might be decompensated by labour and delivery are also accepted indications. Low doses of long-acting local anaesthetics alone or in combination with low doses of fentanyl or sufentanil provide good quality analgesia and are safe for mother and fetus. Test doses in parturients lack sufficient specificity and sensitivity for detecting inadvertent intravascular injection, and subarachnoid migration of the catheter is possible at any time during the procedure. Therefore, every injection must be considered as a test dose and only fractionated injections must be made. Epidural block to T10 is needed for labour and to level T4 for Caesarean section. Maintenance of the block with a continuous infusion, or patient-controlled epidural analgesia with a background continuous infusion, provides more stable analgesia than by intermittent injection. Technical difficulties, dural tap, bloody tap, hypotension and insufficient block are most frequent complications of epidural block in obstetrics. Excessive motor block prolongs the second stage of labour and increases the frequency for instrumental delivery and is therefore considered a complication.

Although lasers have been used in periodontal therapy for 10 or more years, clinicians have barely begun to tap the enormous potential of this form of therapy. The relative lack of pain, ease of use, and site specificity of the laser make it an ideal addition to the periodontist's armamentarium. Applications now are being developed for a broader range of wavelengths that will offer useful, predictable, and comfortable therapy for managing the periodontal patient.

An initial analgesia followed by hyperalgesia to phasic noxious stimuli occurs after ingestion of sucrose ad libitum. However, the mechanism underlying hyperalgesia is not known. The present study was designed to explore the role of VMH in the mediation of the hyperalgesic effect of sucrose ingestion. Adult male albino rats received sucrose solution (20% p.o.) in addition to laboratory food pellets and tap water ad libitum. Their behavioural responses to various phasic and tonic noxious stimuli were recorded after 6, 12 and 48 h during pre and post-sucrose fed states in both the control and VMH lesion groups of rats. Sucrose feeding to control rats significantly reduced the tail flick latency (TFL) and threshold of vocalization during stimulus (SV) and after discharge (VA) indicating hyperalgesia, while the threshold of tail flick remained unaffected. The average pain rating during the formalin test (tonic pain) decreased significantly indicating analgesia. VMH lesion decreased the latency (mean +/- SD) for tail flick (11.26 +/- 4.65 from 15.61 +/- 5.12 s), threshold (median) for tail flick (0.04 from 0.08 mA), vocalization during stimulus (0.05 from 0.1 mA) and vocalization after discharge (0.15 from 0.2 mA), while the tonic pain rating increased, thereby suggesting a hyperalgesic state. However, sucrose feeding to lesioned rats neither potentiated nor attenuated their hyperalgesia. The results suggest that sucrose feeding for 6-48 h ad libitum produces hyperalgesia to phasic noxious and analgesia to tonic noxious stimuli, while VMH lesion produces hyperalgesia to both phasic and tonic noxious stimuli. Secondly, sucrose ingestion by VMH lesion rats does not affect their responses to pain, suggesting the possible role of VMH in the mediation of sucrose-fed nociceptive responses.
