Abstract
The authors conducted a systematic review to assess the effectiveness of extracorporeal shock wave therapy (ESWT) for the treatment of calcific and noncalcific tendonitis of the rotator cuff. Conservative treatment for rotator cuff tendonitis includes physiotherapy, nonsteroidal antiinflammatory drugs, and corticosteroid injections. If symptoms persist with conservative treatment, surgery is often considered. Extracorporeal shock wave therapy has been suggested as a treatment alternative for chronic rotator cuff tendonitis, which may decrease the need for surgery. Articles for this review were identified by electronically searching Medline, EMBASE, Cumulative Index to Nursing & Allied Health Literature (CINAHL), and Evidence Based Medicine (EBM) and hand-screening references. Two reviewers selected the trials that met the inclusion criteria, extracted the data, and assessed the methodological quality of the selected trials. Finally, the strength of scientific evidence was appraised. Evidence was classified as strong, moderate, limited, or conflicting. Sixteen trials met the inclusion criteria. There were only five randomized, controlled trials and all involved chronic (>/=3 months) conditions, three for calcific tendonitis and two for noncalcific tendonitis. For randomized, controlled trials, two (40%) were of high quality, one (33%) for calcific tendonitis and one (50%) for noncalcific tendonitis. The 11 nonrandomized trials included nine that involved calcific tendonitis and two that involved both calcific and noncalcific tendonitis. Common problem areas were sample size, randomization, blinding, treatment provider bias, and outcome measures. There is moderate evidence that high-energy ESWT is effective in treating chronic calcific rotator cuff tendonitis when the shock waves are focused at the calcified deposit. There is moderate evidence that low-energy ESWT is not effective for treating chronic noncalcific rotator cuff tendonitis, although this conclusion is based on only one high-quality study, which was underpowered. High-quality randomized, controlled trials are needed with larger sample sizes, better randomization and blinding, and better outcome measures.

Abstract
In this article, we report two new human leukocyte antigen-C (HLA-C) alleles, HLA-Cw*0314 and Cw*1511, which were identified during routine tissue typing of donors for the Australian Bone Marrow Donor Registry and Australian Cord Blood Bank. HLA-Cw*0314 shows six codon changes in exon 3 compared to Cw*030401 and shares some sequence homology with Cw*07 alleles. Cw*1511 has two nucleotide changes compared with Cw*150201 in exon 2, both resulting in amino acid changes in the protein sequence.

Abstract
A 49-year-old woman presented with a 1-year-history of a widespread eruption which proved to be due to leukaemia cutis. Subsequently, she developed pancytopaenia and a bone marrow biopsy revealed refractory anaemia with excess blasts in transformation (RAEB-T) with a high monoblastic component. This transformed into acute myeloid leukaemia. Leukaemia cutis in this context is well described but in this patient it became manifest 1 year prior to referral to the dermatologist. When occurring with a myelodysplastic syndrome, leukaemia cutis often heralds malignant transformation to acute myeloid leukaemia. Prompt diagnosis in this situation may identify a group of high-risk patients with myelodysplastic syndrome for whom chemotherapy and allogenic bone marrow transplantation, rather than the more conventional approach of supportive treatment, could be a more appropriate management strategy.

Abstract
Recent technological advances have made feasible universal newborn hearing screening and therefore early detection of permanent childhood hearing impairment. Over the past three years, new information has been published on whether early intervention is beneficial, the possibility of harm arising from newborn screening, and its cost. Dramatic progress has been made in the large scale implementation of universal screening in many parts of the western world.

Abstract
The high burden of disease in developing countries often makes it difficult for health systems in these countries to attain the same level of specialist skills as industrialized countries. Technology transfer is one way to improve specialist skills whilst at the same time reducing the burden of disease. This paper describes the use of teleophthalmology, a form of telemedicine, as a mode of technology transfer between the United Kingdom and South Africa. As the burden of eye disease in South Africa is high, the country cannot afford the level of ophthalmic specialization achieved in the UK. The paper estimates the cost-effectiveness of the technology transfer project in terms of a cost per Disability Adjusted Life Year (DALY) averted. We found the technology transfer project to be cost-effective in reducing the burden of eye disease, and that practitioners in South Africa also learned novel procedures that could help future patients and improve cost-effectiveness. Technology transfer using telemedicine is a cost-effective method that richer countries can employ to aid capacity building in the health care systems of poorer countries.

Abstract
PURPOSE This study examined behavioural and emotional problems, social competence and family functioning of hospitalized Chinese children in Hong Kong and the Chinese Mainland. METHOD A sample of 210 hospitalized children (ages 2-11 years) and their families participated in the study. The families were from a cross-section of geographical areas in Hong Kong (two hospitals) and the Chinese Mainland (five hospitals). Parents completed an age-appropriate Chinese version of the Child Behaviour Checklist and the Family Assessment Device. Multiple regression models were used to examine predictors of children's behaviour problems. RESULTS Behavioural patterns appeared to be specific to the developmental stage. Children had greater problems when their families demonstrated poorer affective involvement. Hospitalized children on the Chinese Mainland experienced more internalizing and externalizing behaviour problems than those in Hong Kong. Sick children, according to their parents, however, demonstrate some resiliency based on social and academic competency factors. CONCLUSIONS Hospitalized Chinese children manifest behavioural, emotional and family problems that vary by region, the child's development and gender. Problems predominantly of an internalizing nature characterized this group. The findings support the need for culturally appropriate behavioural assessments and interventions with hospitalized children.

Abstract
AIM To evaluate interobserver agreement for clinical signs in trabeculectomized eyes when examined face-to-face with slit-lamp biomicroscopy (SL) or by remote examination using telemedicine (real-time remote video imaging; TM). METHOD A system for examining trabeculectomized eyes was devised and validated. A prospective randomized interobserver agreement study was then undertaken to compare standard SL biomicroscopy and TM. Remote examination was performed using a 384 kbps Sony 5100 videoconferencing system. Three ophthalmologists each examined 40 eyes of 40 patients, who had previously undergone trabeculectomy. In rotation, two examiners used SL biomicroscopy. The third examined the eye remotely by TM. Analysis was performed to determine the variability in clinical signs and the presence or absence of systematic bias between ophthalmologists and examination methods. RESULTS High levels of agreement were observed for paired examinations by SL biomicroscopy (SL/SL) for bleb vascularity (score range 0-10) with no systematic bias. Paired examination by SL and TM (SL/TM) also showed good levels of agreement for bleb vascularity, although the spread of disagreement was wider (95% limits of agreement 2.57 vs 2.98 (P=0.054)). For anterior chamber depth, observers agreed within +/- 10% of anterior chamber depth for 68% of eyes (SL/SL) and 51% of eyes (SL/TM) (P=0.68). Agreement was 'good' for wall thickness (kappa=0.63 +/- 0.08), bleb height (kappa=0.67 +/- 0.1), and the existence of bleb leak (kappa=0.63 +/- 0.19), but poor for bleb morphology (kappa=0.26 +/- 0.12). For the SL/TM comparison, agreement was fair for wall thickness (kappa=0.39 +/- 0.13), poor for bleb height (kappa=0.17 +/- 0.12), good for bleb leak (kappa=0.56 +/- 0.19), and fair for bleb morphology (kappa=0.31 +/- 0.12). Microcysts were not reliably detected using either technique. CONCLUSION SL biomicroscopy and TM telemedicine examination may permit reliable clinical assessment of trabeculectomized eyes. However, remote examination with TM is more limited with respect to assessing bleb height and bleb wall thickness. The assessment of bleb morphology and microcysts was unreliable with both instruments. We propose that TM examination of trabeculectomized eyes appears safe and appropriate in situations where face-to-face examination by an ophthalmologist is not practical.

Abstract
We compared two methods of assessing clinician satisfaction with telemedicine. Clinicians completed a self-administered questionnaire with a preference ranking scale and a discrete choice method. Sixty-three clinicians completed the questionnaire (a 78% response rate). The preference ranking method showed that clinicians ranked the level of skill of the other clinician as the most important (55%) attribute of a teleconsultation and the completeness of the history as the second most important attribute (42%). The discrete choice method showed that clinicians ranked completeness of the patient's history as the most important attribute and risk of receiving wrong advice as the second most important. The use of discrete choice preferences provides an alternative and more objective method for collecting data about preferences in telemedicine. However, its use is not simple and requires the participants to be engaged in person rather than sent a questionnaire by post.

Abstract
OBJECTIVES All dental surgeons should be protected from hepatitis B virus (HBV) infection by immunisation, ideally administered and monitored via occupational health services (OHS). This study examined relevant OHS systems in place for dental primary care healthcare workers (DHCW) across all Health Board Areas (HBAs) in Scotland. It also explored the DHCWs' knowledge of, and access to, these systems in three HBAs. METHODS Data from senior staff in all Scottish Health Boards and Primary Care Trusts were collected by self-completing questionnaires. Information from DHCWs was collected via telephone interviews with General Dental Practitioners (GDPs) and Community Dental Officers (CDOs) in each of Ayrshire and Arran, Highland and Lothian Health Boards. RESULTS Thirteen of the 15 HBAs had robust HBV vaccination and monitoring systems. However, only 7/15 (47%) of these covered all DHCWs. Seven HBAs provided vaccination and monitoring for CDOs only, leaving GDPs to undertake these responsibilities for themselves. Of the 105 DHCWs approached, 82 gave an interview. These interviews highlighted major differences between HBAs in relation to access of DHCWs to OHS and indicated that CDOs had greater access than GDPs to OHS. Overall, 31% of DHCWs were not satisfied with the OHS available. CONCLUSION In order to safeguard both staff and patients, significant further work is required to ensure that all DHCWs have access to appropriate OHS support for provision and monitoring of immunisation procedures and related functions such as management of sharps injuries.

Abstract
In 1995 the P2X3 receptor was found to be expressed at high levels in nociceptive sensory neurones, consistent with earlier reports that ATP induced pain in humans and animals. At first it was thought that ATP was most likely to play a role in acute pain, following its release from damaged or stressed cells and since then a wide variety of experimental techniques and approaches have been used to study this possibility. Whilst it is clear that exogenous and endogenous ATP can indeed acutely stimulate sensory neurones, more recent reports using gene knockout and antisense oligonucleotide technologies, and a novel, selective P2X3 antagonist, A-317491, all indicate that ATP and P2X3 receptors are more likely to be involved in chronic pain conditions, particularly chronic inflammatory and neuropathic pain. These reports indicate that P2X3 receptors on sensory nerves may be tonically activated by ATP released from nearby damaged or stressed cells, or perhaps from the sensory nerves themselves. This signal, when transmitted to the CNS, will be perceived consciously as chronic pain. In addition, it is now clear that several subtypes of P2Y receptor are also expressed in sensory neurones. Although their distribution and functions have not been as widely studied as P2X receptors, the effects that they mediate indicate that they might also be considered as therapeutic targets in the treatment of pain. Although our ability to treat persistent painful conditions, such as chronic inflammatory and neuropathic pain, has improved in recent years, these conditions are often resistant to currently available therapies, such as opioids or non-steroidal anti-inflammatory drugs. This reflects a limited understanding of the underlying pathophysiology. It is now clear that the development and maintenance of chronic pain are mediated by multiple factors, but many of these factors, and the receptors and mechanisms through which they act, remain to be identified. Chronic pain is debilitating and can greatly decrease quality of life, not just due to the pain per se, but also because of the depression that can often ensue. Thus a greater understanding of the mechanisms that underlie chronic pain will help identify new targets for novel analgesics, which will be of great therapeutic benefit to many people.

Abstract
Hepatitis C virus (HCV) is considered a serious occupational hazard for healthcare workers, particularly those performing exposure-prone procedures. In the UK, the majority of dental procedures are classified as exposure prone. In order to gauge the prevalence and determinants of infection among dental healthcare workers, a voluntary anonymous survey of HCV infection among primary care dental workers employed in the West of Scotland was undertaken, in which occupational and personal risk data were collected in parallel with a blood specimen. The overall prevalence of HCV antibodies was 0.1% (1/880, 95% CI 0-0.6); this is no greater than the estimated prevalence of HCV infection in the local population. Personal risk data collected suggested that the single infection identified was acquired through a non-occupational route. These results suggest that HCV infection is not a major occupational risk for dental healthcare workers.

Abstract
OBJECTIVES To assess the accuracy and efficiency of telemedicine in diagnosing and managing eye problems presenting to accident and emergency departments. DESIGN A controlled trial with a face-to-face and telemedicine phases, each involving 40 patients undergoing two consecutive consultations. In the face-to-face phase, both consultations were in person; in the telemedicine phase, observer 1 used videoconferencing technology at 384 kbit/s (separate nonslit lamp-torchlight and slit lamp examinations) and observer 2 saw the patient face to face. Setting The accident and emergency department at Moorfields Eye Hospital.Participants In total, 80 consenting new patients presenting to the department. MAIN OUTCOME MEASURES (1) Agreement levels between the two observers for each phase (judged by an independent masked investigator), (2) length of consultation, and (3) number of unnecessary recalls. RESULTS Agreement rates were as follows. Face-to-face phase: total agreement (30/40=75%), trivial disagreement (8/40=20%), clinically important disagreement (2/40=5%). Telemedicine phase (torchlight): complete agreement (16/40=40%), trivial disagreement (20/40=50%), clinically important disagreement (4/40=10%). Telemedicine phase (slit lamp): total agreement (23/40=58%), trivial disagreement (15/40=37%), clinically important disagreement (2/40=5%). Agreement levels in the telemedicine phase with torchlight examination were significantly lower (chi(2)=10.07, P=0.007) for any disagreement. Telemedicine consultations erred on the side of clinical caution and were no slower than face-to-face consultations (mean 6 min for observer 1 in both phases). Recalls were more likely (chi(2)=5.16, P=0.02) after telemedicine consultations with torchlight only (9/40) compared with face-to-face consultations (2/40). Although there were more significant disagreements using the telemedicine, in each case the telemedicine diagnosis and management erred on the side of safety; hence, no patient would have suffered by wrong management because of the consultation using telemedicine. CONCLUSIONS Telemedicine was found to be an accurate, safe, and efficient method of diagnosing and managing these patients, especially if slit lamp images were used. Advice using telemedicine erred on the side of caution, which resulted in more recalls.

Abstract
The International Mental Health Task Force participated actively from the outset of the revision of the ICIDH and development of the ICF. The Task Force was responsible for development of all aspects of functioning and disability associated with mental disorders. Building upon knowledge gained since the publication of the ICIDH, it had unique responsibility for development of the ICF chapter on mental functioning. It was also responsible to assure the ICF section on activities and participation integrated and reflected the functioning and disability associated with mental disorders without the redundancy of ICIDH. As context to the revision, the article describes the relationship of diagnostic classifications of mental disorders with disability, and analyses the mental disorder aspects of impairments and disabilities in the ICIDH. Membership in the Task Force represented diversity in geographical, cultural, professional, and personal perspectives on disabilities. This diverse acumen was focused on a range of activities that both specified the unique aspects of functioning and disability associated with mental disorders and assured inclusion of the mental health perspective on the domains of functioning and disability common to physical conditions. Finally, the article notes four current applications of the ICF that are inclusive of the mental health perspective.

Abstract
PURPOSE An evidence-based clinical practice guideline was developed to ascertain the risks and benefits for manipulation or mobilization in treating mechanical neck disorders with or without radicular findings or cerviogenic headache. Pain, function, patient satisfaction and adverse events were appraised. METHODS The practice guideline development cycle/model and Cochrane reviewing process, critiquing past reviews, randomized trials and surveys were used. RESULTS Manipulation and mobilization alone showed similar effects as placebo, wait period, or control group, and appeared similar in benefit for pain relief. While high-technology exercises were superior to manipulation alone for improving long-term pain scores, manipulation plus low-technology exercise had the same effect. Patient satisfaction scores favoured manipulation plus low-technology exercise over manipulation alone, and high-technology exercise alone. Multi-modal care including some combination of manipulation or mobilizations and exercise was superior to control, other physical medicine methods, and rest. Based on weak evidence, estimates for serious complication for manipulation ranged from one in 20,000 to five in 10,000,000. RECOMMENDATIONS Stronger evidence suggests a multi-modal management strategy using mobilization or manipulation plus exercise is beneficial for relief of mechanical neck pain. Weaker evidence suggest less benefit to either manipulation/mobilization done alone than when used with exercise. The risk rate is uncertain.

Abstract
The P2 receptors that mediate contraction of the rat isolated small (SPA, 200-500 micro m i.d.) and large (LPA, 1-1.5 mM i.d.) intrapulmonary arteries were characterized. 2 In endothelium-denuded vessels the contractile order of potency was alpha,beta-methyleneATP (alpha,beta-meATP)>>UDP=UTP=ATP=2-methylthioATP>ADP in the SPA and alpha,beta-meATP=UTP>or=UDP>2-methylthioATP, ATP>>ADP in the LPA. alpha,beta-meATP, 2-methylthioATP and ATP had significantly greater effects in the SPA than the LPA (P<0.001), but there was no difference in the potency of UTP or UDP between the vessels. 3 In the SPA, P2X1 receptor desensitisation by alpha,beta-meATP (100 microM) inhibited contractions to alpha,beta-meATP (10 nM-300 microM), but not those to UTP or UDP (100 nM-300 microM). In the LPA, prolonged exposure to alpha,beta-meATP (100 microM) did not desensitize P2X receptors. 4 Pyridoxalphosphate-6-azophenyl-2',4'-disulphonic acid (PPADS), suramin and reactive blue 2 (RB2) (30-300 microM) inhibited contractions evoked by alpha,beta-meATP. UTP and UDP were potentiated by PPADS, unaffected by RB2 and inhibited, but not abolished by suramin. 1 and 3 mM suramin produced no further inhibition, indicating suramin-resistant components in the responses to UTP and UDP. 5 Thus, both P2X and P2Y receptors mediate contraction of rat large and small intrapulmonary arteries. P2Y agonist potency and sensitivity to antagonists were similar in small and large vessels, but P2X agonists were more potent in small arteries. This indicates differential expression of P2X, but not P2Y receptors along the pulmonary arterial tree.

Abstract
Neck disorders are common, disabling and costly. Randomized trials were reviewed using a Cochrane format, to determine if manual therapy improves pain, function and patient satisfaction in adults suffering from neck disorders with and without radicular findings or headache. Sequenced computerized searches ended in December 1997. Two independent reviewers extracted data while three assessed trial quality. Standard mean difference and relative risks were translated to number needed to treat (NNT) and the percent treatment advantage. The 20 selected trials' quality was 2.4 (SD: 1.04) on the 5-point scale described by Jadad. Trials were clinically heterogenous. Manipulation alone, mobilizations alone, manipulation/mobilization and treatments including massage consistently showed similar effects to placebo, wait period or control. Multimodal manual therapy care including exercise were superior to a control, to certain physical medicine methods and to rest for pain and patient satisfaction. The NNT for a clinically important reduction in pain varied from 2 to 11 and treatment advantage from 6% to 41% at the cost of benign transient side-effects. While results remain inconclusive, some clinical themes have emerged. For mechanical neck disorder with or without headache, it appears that to be most beneficial, manual therapies should be done with exercise for improving pain and patient satisfaction. Manipulation and mobilization alone appear to be less effective. Factorial design would help delineate the magnitude of effect for each component of care.

Abstract
OBJECTIVE The purpose of the study was to examine caregiver understanding of the impact of child sexual abuse and the management of abused children in residential treatment. METHODS A purposive sample of 20 registered nurses and child care workers were interviewed about their experiences working in residential treatment and their knowledge about child development and child sexual abuse and its application to practice. Data from interviews and field notes were analysed using dimensional analysis. FINDINGS Caregivers had limited knowledge of the sequelae of child sexual abuse. Developmentally appropriate behaviour of sexually abused children, as well as behavioural manifestations of child sexual abuse, were often misinterpreted and mismanaged. CONCLUSION Residential care of sexually abused children should be based on sound developmental principles and caregiver sensitivity.

Abstract
OBJECTIVE Positron emission tomography (PET) scanning is more sensitive at detecting metastatic disease than conventional radiological techniques. For patients with pulmonary metastatic melanoma, we investigate if PET scanning to detect occult extra pulmonary disease prior to thoracotomy and metastectomy is associated with improved survival compared to patients staged by conventional radiology. METHODS Between November 1984 and December 1999, 121 patients (90 males, 31 females) have undergone a thoracotomy and pulmonary metastectomy for metastatic melanoma. The age range was 19-84 years (mean 57, median 59). In every case all palpable nodules were removed and the diagnosis confirmed histologically. A total of 68 (56%) patients had a PET scan preoperatively, 53 (44%) underwent conventional or nuclear imaging. Patients with only radiologically isolated pulmonary disease are included. RESULTS Survival is 100% complete and totals 238 pt/years (mean 2.2 years, median 1.4 years). Survival (+/-SE) at 1, 3, 5 and 7 years for all patients is 68% (+/-4.5) (n=67), 36.6% (+/-5.2) (n=27), 22.1% (+/-4.8) (n=15) and 13.5% (+/-4.2) (n=7), respectively. Survival (+/-SE) was significantly better at 3 and 5 years in patients who underwent a PET scan preoperatively (Log rank P=0.002). There was no significant difference in survival by 7 years. CONCLUSIONS There is a significant survival benefit associated with excluding extra pulmonary disease using a PET scan prior to thoracotomy and metastectomy. We recommend that PET scanning be used in the investigation of patients with pulmonary metastatic melanoma prior to metastectomy.

Abstract
A tele-ophthalmology service was established between a regional hospital in South Africa and a specialist eye hospital in the UK. The aim of the service was to provide secondary specialist advice in the diagnosis and treatment of difficult ophthalmology cases in South Africa. Over 12 months, the South African medical officers saw 16,458 ophthalmology patients and would have liked a second opinion in 5.7% of these cases. Case discussions conducted by videoconferencing at 384 kbit/s were carried out in 0.5% of cases. No significant connection problems were experienced during the 12-month study period. On 4% of occasions, the case discussions were conducted at a bandwidth of 256 kbit/s, but this did not affect the quality of the still images. The South African medical officers valued the educational benefits gained from the case discussions with the UK specialists.

Abstract
We studied the clinical outcome of examination of a group of patients with adnexal (eyelid and orbit) conditions. Seventeen patients with adnexal problems were assessed by an ophthalmologist at a distance using telemedicine, and then subsequently by an ophthalmologist in a face-to-face consultation. Measurements such as palpebral aperture, levator muscle function and eyelid skin crease position were recorded. The clinical outcomes from both consultations were recorded independently by the consultants and then compared. The study showed that certain adnexal conditions, such as congenital and involutional ptosis, could be accurately assessed using telemedicine, but that other conditions, such as socket problems in patients who had a previous enucleation or those with non-specific ocular pain with less clear-cut features, were better assessed in a face-to-face consultation. Overall, teleconsultations appeared to be suitable for the assessment of uncomplicated ptosis but not for less well defined conditions. Other factors, such as family dynamics and language problems, also limited the usefulness of the technique.
