It is the attempt of this study to determine the efficacy of response to acupuncture at 24 hours, one week, and three week intervals at the end of a series of treatments in 328 patients. Treated for a variety of disorders, approximately 60% had satisfactory responses of up to 3 weeks duration. The 328 patients were classified into 13 categories of problem disorders: headaches, cervical pain, lumbar pain without radiation, lumbar pain with radiation, isolated sciatica, parathoracic pain, knee pain, elbow pain, shoulder pain, gereralized musculoskeletal pains (rheumatism), neurological disorders, and a general miscellaneous category. The problem disorders were then arranged into etiological categories. In general for each problem disorder, except for neurological, the average response ranged in the 60-65% range at the third week interval.

The medical reasons for rejection among 3,000 consecutive applicants for flight training were evaluated, and the effectiveness of the screening process determined by reviewing subsequent medical wastage occurring during flight training. Of the 46 cadets who left the course because of medical reasons, 8 withheld information which would have led to their rejection on the original screening examination (epilepsy 1, recurrent syncope 1, migraine headache 2, Crohn's disease 1, asthma 1, chronic knee pain 1, and chronic recurrent headaches 1). There were also two errors in medical processing. The other 36 cases could not have been predicted by current screening procedures. We conclude that the major deficiency in our screening process is the concealment or withholding of information by candidates for flight training.

Clinical research can be influenced by many factors that are capable of invalidating results, and one of these factors is known as the Hawthorne effect: the mere awareness of being under observation can alter the way in which a person behaves. In experimental research this effect can be the undesired effect of the experiments themselves, and the stronger its presence, the greater it can influence the results. In anesthesia practice, owing to the particular emotional condition of a patient facing a surgical operation, the Hawthorne effect could be especially strong. The aim of our study was to show the impact that the knowledge of being included in a study has (Hawthorne effect), by comparing the postoperative changes in psychological well-being in two groups of patients undergoing knee arthroscopy and receiving different information about the study from the anesthetist during the preoperative interview. Other signs and symptoms such as postoperative knee pain, nausea, vomiting (the most feared occurrences), headache, return of spontaneous diuresis, analgesic request, anesthesia complications, as well as the intensity of anxiety were also assessed as secondary endpoints. Our results show that subjects who were aware that they were part of a study scored significantly better on postoperative measures of psychological well-being and postoperative knee pain, compared to subjects who were unaware. The size of the effect, as measured by the odds ratio, remains unchanged when controlling for potential confounding factors. The study has enabled us to demonstrate the presence of the Hawthorne effect in clinical research. Therefore, the Hawthorne effect should be acknowledged and accounted for in the design of a study and in the interpretation of results.

Stimulation techniques (SB) include manipulation, acupuncture, acupressure, physiotherapy, transcutaneous electrical nerve stimulation, reflexotherapy, laser treatment and epidural stimulation technique. The purpose of this paper is to investigate the scientific evidence for these techniques. The Cochrane Library and Medline were searched for all techniques from 2000 to date. Only randomised controlled studies written in English were included. Search words were used, such as; acupuncture and neck pain, shoulder pain, etc. In total 587 papers were identified for the following diseases; headache, neck pain, shoulder pain, elbow pain, low back pain and knee pain. 415 papers were excluded, and the remaining 172 papers, a total of 20,431 patients, are the basis for this study. The effect of acupuncture and epidural stimulation technique is scientifically well-supported. For the remaining techniques, the scientific evidence is dubious.

A prognostic approach to defining chronic pain has been proposed as an alternative to traditional definitions based on retrospective duration of pain. While this new approach performs well in low back pain (LBP), headache and orofacial pain, it is not known whether it translates to regional pain syndromes with an underlying pathological component, such as osteoarthritis (OA). We investigated the performance of this approach in a population-based cohort of older adults reporting knee pain, with a spectrum of radiographic knee OA. 676 adults (50 years+) attended a research clinic and were followed up at 18 months and 3 years. Risk scores were calculated using pain intensity, pain duration, pain-related activity, number of pain sites and depressive symptoms, measured at baseline and at 18 months. These scores were used to determine the probability of future clinically significant knee pain, defined as Chronic Pain Grade II-IV, at 18 months and at 3 years using logistic regression. Cut-points on the risk score were applied to determine groups at intermediate (probability >or=0.2), possible (>or=0.5) and probable (>or=0.8) risk of clinically significant knee pain. Discriminative ability of the risk scores, determined by area under the ROC curve, was high (0.78-0.82), varied little by radiographic severity and was superior to pain duration alone. The derived cut-points suggested a lower threshold for each of the risk groups than the previous LBP work. This prognostic approach to defining chronic pain appears to translate well to knee pain. Different cut-points for defining risk groups may be needed for different pain syndromes.

With the aging of the baby boomer generation, the number of patients with osteoarthritis (OA) is expected to swell, posing treatment challenges. Viscosupplementation, in which hyaluronic acid (HA) is injected into the knee joint, has evolved into an important part of our current therapeutic regimen in addressing the patient with knee pain due to OA. Although suffering from lack of an "evidence-based" approach, and largely funded by industry, there is a growing body of outcome data demonstrating the efficacy of HA in decreasing pain and improving function in patients with knee OA, although no evidence indicates that HA is in any way chondroprotective. The clinical success of HA has led to the ongoing introduction of various forms of HA, although little data are available to justify one over the other.

Chronic musculoskeletal conditions are increasingly conceived as involving altered central nervous system processing, and impaired nociceptive flexor reflex (NFR) appears to reflect altered central nervous system processing. The primary objective was to synthesize the evidence for impaired NFR in these conditions. The secondary objective was to evaluate the NFR stimuli parameters employed by reviewed studies. Electronic databases: MEDLINE, CINAHL, Embase, PEDro, Google Scholar, and Cochrane library were searched from the mid-1960s to June 2010. Experimental reports were systematically reviewed and meta-analysis (where possible) was performed. NFR thresholds and parameters of NFR stimuli were extracted. Sixteen trials were identified, 11 of which were suitable for inclusion in the meta-analysis. Compared to healthy controls, standardized mean differences in NFR threshold were significantly lower in subjects with primary headache (-0.45; 95% confidence interval [CI] -0.77 to -0.13, P=0.005), fibromyalgia (-0.63; 95% CI -0.93 to -0.34, P<0.0001), knee pain (-1.51; 95% CI -2.10 to -0.93, P<0.00001) and whiplash (-0.73; 95% CI -1.11 to -0.35, P=0.0002). Employed stimuli parameters vary between studies, with inter-pulse duration (P=0.044) being identified by multiple regression analysis as independent predictors of the variability in NFR threshold in healthy controls. The results indicate that there is evidence of central hyperexcitability in people with chronic musculoskeletal pain. Our review also suggests that shorter inter-pulse duration tends to yield smaller variability in NFR threshold. However, further research investigating optimal stimulation parameters is still warranted.

Background There is relatively limited knowledge about the practitioners who provide acupuncture treatment within the UK, what conditions patients consult for and the treatment provided. Objectives To characterise the conditions treated and by whom, to examine characteristics of the treatment and to explore trends over time. Method A cross-sectional survey of the UK acupuncture practitioners was conducted; 800 practitioners were selected by computer-generated randomisation sequences from the four major UK-based professional associations. Data collected on the practitioners included demographic details, association membership, statutorily regulated status, practice setting, style of acupuncture, diagnostic methods and needle response sought. Practitioners recorded details of their 10 most recent patients, including demographic details, primary reason for consulting and lifestyle advice provided. Results 330 practitioners responded comprising doctors (29%) physiotherapists (29%), nurses (15%) and independent acupuncturists (27%): 62% were women with median age of 48 years. The majority (68%) practiced in independent settings and 42% practiced within the National Health Service. Patients most commonly consulted for low back, neck, shoulder and knee pain, as well as headaches and migraine. Treatment for infertility by independent acupuncturists was found to have increased fivefold in 10 years. Conclusion Acupuncture provides a substantial contribution to the healthcare of the UK, with an estimated 4 million sessions provided annually. The primary complaints for which patients consult reflect the growing evidence base on acupuncture for these conditions. These data provide a basis for decision-making regarding policy and practice.

We describe a case of a 33-year-old skydiver who presented to the emergency department after a traumatic landing following a parachuting episode. He initially presented with right knee pain secondary to a tibial plateau fracture. There were no neurological symptoms or signs at the initial assessment. While he was still in the emergency department, he suddenly developed headache and left-sided hemiplegia. An urgent work-up showed right middle cerebral artery thrombosis with right internal carotid thrombosis and dissection. We have discussed some possible mechanism of injury in skydiving that may have predisposed to the occurrence of cervical dissection in our patient.

The Chikungunya (CHIKV) fever is a viral disease produced by a single-stranded RNA Alphavirus from the Togaviridae genus. Its transmission occurs only through mosquito vectors, principally Aedes aegypti. It requires a human-mosquito-human transmission cycle. It is associated with severe arthritis/arthralgias, myalgias, high fever, headache, and maculopapular rash. Joint ache appears to be symmetrical. The virus has an incubation period of 2 to 7 days, where the high fever is typically presented. It is followed by arthralgias and myalgias, and rashes, which last for 3 to 5 days. However, the arthralgias can persist for months after the infection, which can contribute to severe arthritis. As of now, no vaccine exists for the virus and no official treatment has been developed aside from standard procedures of the use of acetaminophen (paracetamol), and non-steroidal anti-inflammatory drugs. This is a case report of a 54-year old Hispanic individual that reported left shoulder pain, left knee pain and fever. The symptoms started on a Saturday in September 2014 in middle of the night. The patient was treated with high doses of intravenous vitamin C over two days. The symptoms resolved after the infusions without any side effects. Based on the positive outcome in this case, we propose that intravenous vitamin C should be studied further as a potential treatment for acute viral infections.
