ABSTRACT
Routine spinal immobilization for trauma patients has become established in developed countries throughout the world. Cervical spinal injury is, however, relatively rare in trauma patients, and immobilization practice was developed largely without firm supporting evidence. In recent years, published evidence has suggested that spinal immobilization may in some cases be harmful. The purpose of this article is to critically review the evidence and the implications for trauma patient management and outcomes. We searched MEDLINE, the Cochrane Database, Index Medicus and article references with a broad search strategy. Relevant results were analysed and critically reviewed in the context of trauma patient management. Our findings present a growing body of evidence documenting the risks and complications of routine spinal immobilization. There is a possibility that immobilization could be contributing to mortality and morbidity in some patients and this warrants further investigation.

The objectives of this paper are to lay out for wider discussion the potential advantages and disadvantages of active military units providing medical care for the local population through ad hoc clinics (MEDCAPS). The literature on this subject has been reviewed and the personal experience of MEDCAPS by the author and other doctors in Helmand Province 2007/8 is presented. Although in the published literature, MEDCAPS are almost universally regarded as being good for relations between the military and civilians, the reality on the ground is that they potentially risk the lives of both staff and patients. and may actually contribute little in terms of relieving suffering, or improving relations between military and civilians. The conclusion of this paper is that MEDCAPs at best have a very limited and specific role, but that there will remain a strong desire from staff on the ground to initiate them.

We prospectively randomised 104 consecutive patients undergoing primary cemented total knee arthroplasty into two groups of 52 patients each, with one group to receive a standard suction drain (Redivac) and the other, an autologous transfusion drain (Bellovac). Randomisation was achieved using the software programme MINIM: , which was set to randomly allocate patients to either of the two groups based on their age, sex and body mass index (BMI). All procedures were performed under pneumatic tourniquet. Drains were released in the recovery room 20 min after surgery and removed 24 h following surgery. Blood collected in the standard suction drain (control group) was discarded, while blood collected in the autologous transfusion drains (study group) was transfused unwashed back to the patient within 6 h of collection. Thirteen patients (25%) in the study group had two or more units of homologous blood transfused in addition to the blood collected postoperatively and re-transfused (average: 438 ml). Twelve patients (23%) in the control group had two or more units of homologous blood transfused. No sepsis, transfusion reactions or coagulopathies were associated with the autologous blood transfused in the study group. The use of the autologous transfusion system (Bellovac) proved to be safe but failed to reduce the need for postoperative homologous blood transfusion following uncomplicated total knee arthroplasty.

This article reports the lessons learnt from a period of retraining and from discussion with others who have been involved in a similar process. The conclusions are that retraining should only be undertaken once there is full agreement between all parties involved that it is necessary and feasible. There must also be agreement in advance of the criteria which will constitute successful retraining, and the actions which will be taken to ensure the rapid return of the retrainee to the type of practice which is being offered and has been accepted. The process of retraining requires especially close supervision and is very stressful for the retrainee. It is likely that this should only be undertaken in units specially staffed and funded to accommodate this type of work.

If the public are to be assured that surgeons are safe, then there must be some form of competence assessment on which a licence to practice is based. However, the assessment and the licence needs to be both appropriate to the training received by the surgeon and to the requirements of the post they propose to take up. The 'key-concept' described in this paper attempts to address this problem.

The current method for selecting surgeons of the future is neither objective nor relevant to present day needs. An assessment is needed which ranks potential trainees according to aptitude, motivation and diligence, all of which is validated. This task should be a core duty for the Royal Colleges of Surgeons working in close co-operation with surgical specialty associations.

OBJECTIVE: To assess whether a new form of teaching, the 'donut round', is as good at imparting factual knowledge as interactive lectures in both the short-term and the long-term. DESIGN: Randomised controlled trial. SETTING: University of Oxford Medical School. PARTICIPANTS: 106 fifth year clinical medical students taught half of their A&E/trauma course by donut round and half by lecture. MAIN OUTCOME MEASURES: The results of multiple choice questions (MCQs) divided according to how the material was taught. Three MCQ papers were set: one at the end of a four-week course, one approximately 10 weeks later and a final exam approximately 17 months after the first. RESULTS: At the first MCQ, the average result for questions taught by donut round was 41.0 (out of 50) and for those taught by conventional lecture was 40.1. At 10 weeks these averages fell to 36.3 and 37.3 and at 17 months they were 38.7 and 38.1, respectively. None of these pairs were significantly different. Ratios were calculated for each candidate by dividing their donut round score by their lecture score. The average ratios for the first, second and third MCQ papers were: 1.029, 1.007 and 1.027, respectively, and were not significantly different. The individual ratios of all candidates in all three MCQs were plotted against their equivalent total mark. The calculated linear regression showed a statistically significant advantage of donut rounds over lectures in those candidates who scored a total mark less than 89 (n=260, p=0.02). CONCLUSIONS: Donut rounds are at least as good as lectures in imparting factual knowledge and may provide a selective advantage to weaker students.

STUDY DESIGN: A randomized trial designed to compare interferential therapy with motorized lumbar traction and massage management for low back pain in a primary care setting. OBJECTIVE: To measure and compare the outcome of interferential therapy and management by motorized lumbar traction and massage. SUMMARY OF BACKGROUND DATA: Management of low back pain by interferential therapy and motorized lumbar traction and massage is common in Germany. No reports of previous randomized trials for the outcome from interferential therapy were found. METHODS: Consenting patients were randomly assigned into one of two groups. A pretreatment interview was performed by the patient using a computer-based questionnaire. It also incorporated the Oswestry Disability Index and a pain visual analog scale. Management consisted of six sessions over a 2- to 3-week period. Oswestry Disability Indexes and pain visual analog scale scores also were obtained immediately after and at 3 months after treatment. RESULTS: A total of 152 patients were recruited. The two treatment groups had similar demographic and clinical baseline characteristics. The mean Oswestry Disability Index before treatment was 30 for both groups (n = 147). After treatment, this had dropped to 25, and, at 3 months, were 21 (interferential therapy) and 22 (motorized lumbar traction and massage). The mean pain visual analog scale score before treatment was 50 (interferential therapy) and 51 (motorized lumbar traction and massage). This had dropped, respectively, to 46 and 44 after treatment and to 42 and 39 at 3 months. CONCLUSIONS: This study shows a progressive fall in Oswestry Disability Index and pain visual analog scale scores in patients with low back pain treated with either-interferential therapy or motorized lumbar traction and massage. There was no difference in the improvement between the two groups at the end of treatment. Although there is evidence from several trials that traction alone is ineffective in the management of low back pain, this study could not exclude some effect from the concomitant massage.

OBJECTIVES: To determine whether a serious paracetamol overdose in the medical television drama Casualty altered the incidence and nature of general hospital presentations for deliberate self poisoning. DESIGN: Interrupted time series analysis of presentations for self poisoning at accident and emergency departments during three week periods before and after the broadcast. Questionnaire responses collected from self poisoning patients during the same periods. SETTING: 49 accident and emergency departments and psychiatric services in United Kingdom collected incidence data; 25 services collected questionnaire data. SUBJECTS: 4403 self poisoning patients; questionnaires completed for 1047. MAIN OUTCOME MEASURES: Change in presentation rates for self poisoning in the three weeks after the broadcast compared with the three weeks before, use of paracetamol and other drugs for self poisoning, and the nature of overdoses in viewers of the broadcast compared with non-viewers. RESULTS: Presentations for self poisoning increased by 17% (95% confidence interval 7% to 28%) in the week after the broadcast and by 9% (0 to 19%) in the second week. Increases in paracetamol overdoses were more marked than increases in non-paracetamol overdoses. Thirty two patients who presented in the week after the broadcast and were interviewed had seen the episode-20% said that it had influenced their decision to take an overdose, and 17% said it had influenced their choice of drug. The use of paracetamol for overdose doubled among viewers of Casualty after the episode (rise of 106%; 28% to 232%). CONCLUSIONS: Broadcast of popular television dramas depicting self poisoning may have a short term influence in terms of increases in hospital presentation for overdose and changes in the choice of drug taken. This raises serious questions about the advisability of the media portraying suicidal behaviour.

Undisplaced fractures of the hip can occasionally be difficult to diagnose on radiographs. We performed MRI scans on 33 patients who had post-traumatic painful hips but negative radiographs. Forty per cent of the patients had sustained a fractured neck of femur, 15 per cent had sustained an intertrochanteric fracture and 11 per cent had sustained other fractures around the hip; in one patient a tumour was demonstrated. No fracture was seen in 30 per cent of the patients scanned. MRI is well tolerated by elderly patients in pain, does not involve ionising radiation and provides early and accurate diagnosis in patients with X-ray negative post-traumatic hip pain.

Survival analysis of joint replacement relies on the assumption that surgical procedures in patients lost to follow-up have the same chance of failing as those in patients who continue to be assessed. Our study questions that assumption. During the 16-year follow-up of 2268 patients who had received total hip replacements 142 (6%) were lost to follow-up. The cumulative loss at 15 years was 20%. At their last assessment, patients who subsequently failed to attend for follow-up had significantly worse pain, range of movement and opinion of their progress (p < 0.001) and significantly worse radiological features than a matched control group (p < 0.01). Patients lost to follow-up have a worse outcome than those who continue to be assessed. Consequently, a survival analysis that does not take into account such patients is likely to give falsely optimistic results. It is therefore essential that vigorous attempts are made to minimise loss to follow-up, and that the rate of such loss is quoted. The overall loss to follow-up disguises the magnitude of the problem, which is best quantified by a cumulative rate of follow-up. The reliability of a study can be assessed by a loss-to-follow-up quotient, calculated by the number of failures: the lower the quotient the more reliable the data. Ideally, the quotient should be less than 1.

We have assessed the relative value of various outcome measures after THR, by the analysis of follow-up data from over 2000 patients. They had been reviewed clinically and radiologically six months after operation, at one year, and then every two years, some for 16 years. At each review their pain level, stiffness and opinion of progress were scored and a radiograph taken. We found that pain level was the most informative outcome as a predictor of revision and correlated well with the patients' opinions. We made a comparison between the six types of implant in the series, using survival analysis and log-rank testing with different pain levels as endpoints. This analysis revealed differences which were not detected by survival analysis using the traditional endpoint of revision. We therefore recommend the use of different levels of pain as the main outcome measures after total hip replacement.

The recommendation that patients having a total hip replacement should receive pharmacological thromboprophylaxis is based on the belief that fatal pulmonary embolism is common, and that prophylaxis will decrease the death rate. To investigate these assumptions we performed a meta-analysis of all studies on hip replacement which included information about death or fatal pulmonary embolism. A total of 130 000 patients was included. The studies were so varied in content and quality that the results of our analysis must be interpreted with some caution. The fatal pulmonary embolism rate was 0.1% to 0.2% even in patients who received no prophylaxis. This is an order of magnitude lower than that which is generally quoted, and therefore the potential benefit of prophylaxis is small and may not justify the risks. To balance the risks and benefits we must consider the overall death rate. This was 0.3% to 0.4%, and neither heparin nor any other prophylactic agent caused a significant decrease. Our study demonstrates that there is not enough evidence in the literature to conclude that any form of pharmacological thromboprophylaxis decreases the death rate after total hip replacement. For this reason guidelines which recommend their routine use to prevent death after hip replacement are not justified.
