Suppression of Experimental Pain by Auriculopressure

In a controlled trial at a University Clinic of Physical Therapy and Rehabilitation, healthy student volunteers were given auriculopressure to investigate its analgesic effect. There were two study groups, each containing 30 volunteers. The first group was given auriculopressure to the toe somatic point on the ear, with pressure sensitivity being measured on the skin of the toe with an algometer device before and after ear stimulation. The control group had the same measurements with placebo stimulation to the ear. In the auriculopressure group the increase in pain threshold was statistically significant. In the placebo control group there was no significant change. These results suggest that auriculopressure could be a useful method for suppression of post-traumatic somatic pain.

Guidelines for the public health management of typhoid and paratyphoid in England: practice guidelines from the National Typhoid and Paratyphoid Reference Group

OBJECTIVES

The Typhoid and Paratyphoid Reference Group (TPRG) was convened by the Health Protection Agency (HPA) and the Chartered Institute of Environmental Health (CIEH) to revise guidelines for public health management of enteric fever. This paper presents the new guidelines for England and their rationale.

METHODS

Methods include literature reviews including grey literature such as audit data and case studies; analysis of enhanced surveillance data from England, Wales and Northern Ireland; review of clearance and screening schedules in use in other non-endemic areas; and expert consensus.

RESULTS

The evidence and principles underpinning the new guidance are summarised. Significant changes from previous guidance include: • Algorithms to guide risk assessment and management, based on risk group and travel history; • Outline of investigation of non-travel cases; • Simplified microbiological clearance schedules for cases and contacts; • Targeted co-traveller screening and a "warn and inform" approach for contacts; • Management of convalescent and chronic carriers.

CONCLUSIONS

The guidelines were launched in February 2012. Feedback has been positive: the guidelines are reported to be clear, systematic, practical and risk-based. An evaluation of the guidelines is outlined and will add to the evidence base. There is potential for simplification and consistency between international guidelines.

National outbreak of Salmonella Java phage type 3b variant 9 infection using parallel case-control and case-case study designs, United Kingdom, July to October 2010

Between July and October 2010, a national outbreak comprising 136 cases of Salmonella Java phage type 3b variant 9 was identified by the Health Protection Agency. Most cases were female. Cases had a median age of 39.5 years and lived in London, the South East and East of England. Parallel case–control and case–case study designs were undertaken to test the generated hypotheses. The case–case study aimed to examine if the infection was associated with eating food items purchased from commercial catering settings, and the reference group comprised non-travel related cases of S. Enteritidis infected during the same time period as the cases. The case–control study was designed to examine if the infection was associated with specific food items purchased from commercial catering settings, and recruited case-nominated controls. However, in response to poor recruitment we adapted our methods to investigate food exposures in the same way. Results of epidemiological investigations are compatible with salad vegetables as the potential source, but no common suppliers of salad were identified and no organisms were isolated from environmental and food samples. Limitations in the case–control study highlight the potential value of using a combination of epidemiological methods to investigate outbreaks.

National outbreak of Salmonella Enteritidis phage type 14b in England, September to December 2009: case-control study

We conducted an unmatched retrospective case–control study to investigate an upsurge of non-travel-related sporadic cases of infection with Salmonella enterica subsp. enterica serotype Enteritidis phage type 14b with antimicrobial resistance to nalidixic acid and partial resistance to ciprofloxacin (S. Enteritidis PT 14b NxCp(L)) that was reported in England from 1 September to 31 December 2009. We analysed data from 63 cases and 108 controls to determine whether cases had the same sources of infection as those found through investigation of 16 concurrent local foodborne outbreaks in England and Wales. Multivariable logistic regression analysis adjusting for age and sex identified food consumption at restaurants serving Chinese or Thai cuisine (odds ratio (OR): 4.4; 95% CI: 1.3–14.8; p=0.02), egg consumed away from home (OR: 5.1; 95% CI: 1.3–21.2; p=0.02) and eating vegetarian foods away from home (OR: 14.6; 95% CI: 2.1–99; p=0.006) as significant risk factors for infection with S. Enteritidis PT 14b NxCp(L). These findings concurred with those from the investigation of the16 outbreaks, which identified the same Salmonella strain in eggs from a specified source outside the United Kingdom. The findings led to a prohibition of imports from this source, in order to control the outbreak.

Comparison of cyclic and continuous calcitonin regimens in the treatment of postmenopausal osteoporosis

We aimed to compare and evaluate the efficacies of a continuous regimen of intranasal salmon calcitonin (SCT) and two cyclic regimens (different cyclic regimens from previous studies) based on alternating 15 days or on 10 days consecutively per month for 1 year in the treatment of postmenopausal osteoporosis. We performed an open-label, prospective, randomized clinical trial. A total of 120 postmenopausal osteoporotic participants between 50 and 65 years old were randomly assigned to one of three treatment groups. Patients in group 1 (n = 40) received continuously SCT nasal spray at a dose of 200 IU/day, plus continuously 500 mg/day elementary calcium and 0.25 microg/day 1-alpha hydroxyvitamin D3, for 1 year. Patients in group 2 (n = 40) received cyclically SCT nasal spray at a dose of 200 IU/day on alternating 15 days per month, plus continuously 500 mg/day elementary calcium and 0.25 microg/day 1-alpha hydroxyvitamin D3, for 1 year. Patients in group 3 (n = 40) received cyclically SCT nasal spray on 10 days consecutively per month (20 days/month rest), plus continuously 500 mg/day elementary calcium and 0.25 microg/day 1-alpha hydroxyvitamin D3, for 1 year. Data was evaluated by repeated analysis of variance (ANOVA). In addition, statistical differences between groups were assessed by the two-tailed Student's t test. After 1 year of the study, seven patients from group 1, eight patients from group 2 and five patients from group 3 withdrew from the study. No patient discontinued the study because of adverse drug effects. There was a statistically-significant improvement in pain intensity VAS scores at the end of the year to baseline scores in all three groups (p < 0.001). There was no significant difference in pain intensity VAS scores between groups at the end of the year (p > 0.05). Lumbar and femur neck BMD scores improved significantly at the end of treatment in all three groups (p < 0.05). There was no statistically-significant difference in BMD scores between groups at final (p > 0.05). Urinary DPD/Cre levels decreased significantly in all three groups by the end of the year (p < 0.05). There was no statistically-significant difference in urinary DPD/Cre final levels between groups (p > 0.05). According to the results of the present study, consecutive 10 days therapy with SCT, which is the first in the literature to our knowledge, is as effective as the other two regimens in the treatment of osteoporosis. Both cyclic regimens in our study (alternating 15 days and 10 consecutive days each month for 1 year) do appear to offer some advantages, especially economically and clinically, as compared to continuous treatment.

Duplex and color Doppler sonographic findings in active sacroiliitis

OBJECTIVE

The aim of this study was to describe the duplex and color Doppler sonographic findings in active sacroiliitis.

SUBJECTS AND METHODS

Forty-one joints in 21 patients with active sacroiliitis, 20 sacroiliac joints in 10 patients with osteoarthritis, and 30 sacroiliac joints of 15 asymptomatic volunteers were investigated on duplex and color Doppler sonography. We investigated whether a vessel was present around the posterior portions of sacroiliac joints with color Doppler sonography. When an artery was detected, the resistive index (RI) was measured using duplex Doppler sonography in all groups and also after treatment in the patients with active sacroiliitis.

RESULTS

Vascularization around the posterior portions of sacroiliac joints was seen in 41 joints of the 21 patients with active sacroiliitis, nine joints of six patients with osteoarthritis, and 13 joints of eight volunteers. The mean RI values were 0.62 +/- 0.13, 0.91 +/- 0.09, and 0.97 +/- 0.03, respectively. In the patients with active sacroiliitis, the mean RI value was 0.91 +/- 0.07 after therapy. The RI values for the patients with active sacroiliitis were significantly different from those of the patients with osteoarthritis (p < .001) and of the volunteers (p < .001). In addition, the RI values were significantly different before and after treatment in the patients with active sacroiliitis (p < .001).

CONCLUSION

Vascularization around the posterior portions of sacroiliac joints increased and RI values decreased in patients with active sacroiliitis. Color and duplex Doppler sonography were able to reveal these changes and can be used in the diagnosis of active sacroiliitis and follow-up after treatment. Thus, RI values may be a quantitative indicator for clinical symptoms in patients with active sacroiliitis.

Sleep quality and pain threshold in patients with fibromyalgia

The purpose of the study was to examine the association between the subjective sleep quality and pain threshold in fibromyalgia. Sixteen patients with fibromyalgia were included in the study. The pain threshold was determined using a manual algometer. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. The pain threshold was negatively correlated with the scores for subjective sleep quality, habitual sleep efficiency, and sleep disturbance and the PSQI global score. We conclude that there is a negative correlation between pain and sleep disturbance: increased pain sensitivity is associated with greater sleep disturbance.

Progressive pseudorheumatoid chondrodysplasia: a hereditary disorder simulating rheumatoid arthritis

Progressive pseudorheumatoid chondrodysplasia is a rare hereditary disorder. This autosomal recessive condition is characterised by progressive arthropathy and platyspondyly. The symptoms are similar to those of rheumatoid arthritis but synovitis is absent. In this study a patient with inherited progressive pseudorheumatoid chondrodysplasia is presented.

Effect of transcutaneous electrical nerve stimulation (TENS) on Barthel Activities of Daily Living (ADL) index score following stroke

OBJECTIVE

To evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) and placebo TENS on the level of activities of daily living (ADL) of stroke patients.

SETTING

A university hospital.

PATIENTS

Patients who had had a stroke 30-240 days before entry to a university rehabilitation centre.

DESIGN

Controlled design with block randomization and blinded assessment.

INTERVENTION

All patients had Todd-Davies exercises. In group 1 (n = 30) TENS w th frequency of 100 Hz was used at an intensity that the patient could tolerate; n group 2 (n = 30) patients were given placebo TENS. The treatment protocol consisted of 40 sessions (eight weeks).

OUTCOMES

The Barthel Index for daily living activities was used to measure functional changes over time, and the Ashworth Scale was used to measure spast city in the elbow, knee and ankle. These measurements were made prior to and following the treatment by assessors unaware of the patient's group allocation.

RESULTS

There were 30 patients in each group. Patients in group 1 (active TENS) were more disabled at entry to the study. Statistically significant improvements were recorded in all parameters such as feeding, transfer, hyg ene, toileting, bathing, walking, climbing stairs, dressing, bowel and bladder care for group 1 (p<0.001) but only in some items in group 2. The change in total score was significant in both groups but the difference in the change score between the two groups was statistically significant (p<0.001). Spasticity was reduced in the active treatment group.

CONCLUSION

TENS appears to be an effective adjunct in the regaining of motor functions and improving ADL in hemiplegic patients, but the accidental imbalance in severity of disability at entry makes interpretation uncertain.

Hypnotizability, pain threshold, and dissociative experiences

BACKGROUND

There may be an association between pain threshold, hypnotizability, and dissociative experiences. The purpose of the present study was to examine this association.

METHODS

Forty-one healthy subjects were included in the study. Pain thresholds were determined using a manual algometer. The Dissociative Experiences Scale was administered to all subjects. Hypnotizability of the subjects was assessed by the eye roll sign of the Hypnotic Induction Profile. There were 14, 15, and 12 subjects in the Grade 1, 2, and 3 groups, respectively.

RESULTS

Highly hypnotizable subjects had lower pain thresholds and were more likely to report dissociative experiences than the less hypnotizable subjects.

CONCLUSIONS

There is an association between pain threshold, hypnotizability, and dissociative experiences. It may be suggested that dissociative and somatic symptoms may be integrally linked and related to hypnotic suggestibility.

Distraction of lumbar vertebrae in gravitational traction

STUDY DESIGN

Experimental study of 30 patients diagnosed with low back pain resulting from lumbar disc herniation, disc degeneration, and segmental instability. Patients underwent gravitational traction, and widening of the intervertebral space and posterior facets was measured on radiographs. This same procedure was performed with a group of 30 healthy individuals.

OBJECTIVES

To determine the effect of gravitational traction on the widening of the intervertebral space and the other vertebral structures in patients with low back pain and in healthy individuals.

SUMMARY OF BACKGROUND DATA

Gravitational traction is performed by suspending the patient in a hanging, upright position for an extended period of time. In spite of disagreement among authors about the effect of lumbar traction, recent innovations have enabled the distraction of vertebrae.

METHODS

A specially designed apparatus was used to apply gravitational traction. Pre- and post-traction radiographs were obtained to study the changes in the L2-L3, L3-L4, L4-L5, and L5-S1 intervertebral spaces; Ferguson's angle; L1-S1 total distance; and blood pressure.

RESULTS

Distraction was more than approximately 3 mm in each intervertebral space in both groups.

CONCLUSION

Gravitational traction had a very apparent effect on intervertebral space and was found to be an effective method to distract lumbar vertebrae. Discomfort experienced by the patient during suspension may be overcome by making biomedical changes to the suspension corset.
