Abstract
BACKGROUND Within Europe, the management of pyridoxine (B6) non-responsive homocystinuria (HCU) may vary but there is limited knowledge about treatment practice. AIM A comparison of dietetic management practices of patients with B6 non-responsive HCU in European centres. METHODS A cross-sectional audit by questionnaire was completed by 29 inherited metabolic disorder (IMD) centres: (14 UK, 5 Germany, 3 Netherlands, 2 Switzerland, 2 Portugal, 1 France, 1 Norway, 1 Belgium). RESULTS 181 patients (73% >16 years of age) with HCU were identified. The majority (66%; n=119) were on dietary treatment (1-10 years, 90%; 11-16 years, 82%; and >16 years, 58%) with or without betaine and 34% (n=62) were on betaine alone. The median natural protein intake (g/day) on diet only was, by age: 1-10 years, 12 g; 11-16 years, 11 g; and >16 years, 45 g. With diet and betaine, median natural protein intake (g/day) by age was: 1-10 years, 13 g; 11-16 years, 20 g; and >16 years, 38 g. Fifty-two percent (n=15) of centres allocated natural protein by calculating methionine rather than a protein exchange system. A methionine-free l-amino acid supplement was prescribed for 86% of diet treated patients. Fifty-two percent of centres recommended cystine supplements for low plasma concentrations. Target treatment concentrations for homocystine/homocysteine (free/total) and frequency of biochemical monitoring varied. CONCLUSION In B6 non-responsive HCU the prescription of dietary restriction by IMD centres declined with age, potentially associated with poor adherence in older patients. Inconsistencies in biochemical monitoring and treatment indicate the need for international consensus guidelines.

Abstract
OBJECTIVES To determine whether listening to music during cardiopulmonary resuscitation (CPR) training increases the proportion of lay people delivering chest compressions of 100 per minute. DESIGN Prospective randomised crossover trial. SETTING Large UK university. PARTICIPANTS 130 volunteers (81 men) recruited on an opportunistic basis. Exclusion criteria included age under 18, trained health professionals, and cardiopulmonary resuscitation (CPR) training within the past three months. INTERVENTIONS Volunteers performed three sequences of one minute of continuous chest compressions on a skill meter resuscitation manikin accompanied by no music, repeated choruses of Nellie the Elephant (Nellie), and That's the Way (I like it) (TTW) according to a pre-randomised order. MAIN OUTCOME MEASURES Rate of chest compressions delivered (primary outcome), depth of compressions, proportion of incorrect compressions, and type of error. RESULTS Median (interquartile range) compression rates were 110 (93-119) with no music, 105 (98-107) with Nellie, and 109 (103-110) with TTW. There were significant differences within groups between Nellie v no music and Nellie v TTW (P<0.001) but not no music v TTW (P=0.055). A compression rate of between 95 and 105 was achieved with no music, Nellie, and TTW for 15/130 (12%), 42/130 (32%), and 12/130 (9%) attempts, respectively. Differences in proportions were significant for Nellie v no music and Nellie v TTW (P<0.001) but not for no music v TTW (P=0.55). Relative risk for a compression rate between 95 and 105 was 2.8 (95% confidence interval 1.66 to 4.80) for Nellie v no music, 0.8 (0.40 to 1.62) for TTW v no music, and 3.5 (1.97 to 6.33) for Nellie v TTW. The number needed to treat for listening to Nellie v no music was 5 (4 to 10)-that is, the number of cardiac arrests required during which lay responders listen to Nellie to facilitate one patient receiving compressions at the correct rate (v no music) would be between four and 10. A greater proportion of compressions were too shallow when participants listened to Nellie v no music (56% v 47%, P=0.022). CONCLUSIONS Listening to Nellie the Elephant significantly increased the proportion of lay people delivering compression rates at close to 100 per minute. Unfortunately it also increased the proportion of compressions delivered at an inadequate depth. As current resuscitation guidelines give equal emphasis to correct rate and depth, listening to Nellie the Elephant as a learning aid during CPR training should be discontinued. Further research is required to identify music that, when played during CPR training, increases the proportion of lay responders providing chest compressions at both the correct rate and depth.

Abstract
This paper investigates the feasibility of a telephone clinic follow-up service for patients undergoing carpal tunnel decompression. Six hundred and thirty patients were recruited over a 2-year period and we assessed their outcome and satisfaction level in the service, using a pre-determined questionnaire 6 weeks following surgery. The telephone clinic was overseen by a surgical care practitioner. We followed up 598 patients (93%) in total, and found 42 patients to be dissatisfied with the service (7%). These patients were referred for outpatient consultation and investigation. Most patients were satisfied with their surgical outcome and found the telephone clinic service to be convenient and effective. Cost analysis calculations estimated a potential saving of pound 45,958 over the 2-year period when compared to standard outpatient consultation. This model has been developed in our trust to follow up patients undergoing similar minor hand surgery.

Abstract
INTRODUCTION Dietary management forms the mainstay of treatment for many inherited metabolic diseases (IMDs) and specialist dietitians play a crucial role in the multi-disciplinary core team for these patients. Professional concerns have been expressed that the current clinical workforce is inadequate for meeting current and future service demands. The aim of this work was to describe the provision of specialist dietetics to patients with IMD as part of a national needs assessment and review. MATERIALS AND METHODS The 24 main specialist providers and 27 specialist dietitians were surveyed by a questionnaire. A focus group of three specialist dietitians was also held to explore the roles of specialist dietitians in greater depth. RESULTS Responses were received from all 24 specialist service providers and 63% of 27 specialist dietitians. The majority of service providers (92%) have specialist dietitians, but only eight services had more than one whole time equivalent (33%). Key roles were management of complex dietary regimens, prevention and management of metabolic crises, education, co-ordination of care, clinical audit and research. Although highly qualified, there is currently no clear formal career structure or training pathway for dietitians in IMDs. CONCLUSION Specialist dietitians have important clinical and leadership roles in managing IMD but specialist services are thinly spread. There is a need for access to formal education, training and support programmes. The clinical workforce needs expansion to provide more comprehensive and equitable services.

Abstract
AIM The aim was to study the efficacy and acceptability of MSUD Express in adolescent and adult patients with maple syrup urine disease (MSUD). BACKGROUND There are difficulties associated with current protein substitutes designed for adolescents and adults with MSUD. This can affect their metabolic control. MSUD Express is a new low-volume, nutritionally complete protein substitute, free from leucine, isoleucine and valine and designed specifically for older patients with MSUD. METHODS Four patients with MSUD were included in the trial (aged 16-41 years). Product dosage was 4 x 25 g sachets per day, providing 1264 kJ and 72 g amino acids: more than adequately meeting requirements for all micronutrients. RESULTS At the start of the study, the mean (range) of the previous eight leucine concentrations (on MSUD Aid III) was 564 micromol/L (430-817 micromol/L) and during the study (on MSUD Express) was 382 micromol/L (181-603 micromol/L). The average percentage fall in mean leucine concentrations was 32%. In patients 2, 3 and 4, low leucine levels resulted in an increase in the natural protein allowance per day. MSUD Express was rated as 'excellent' or 'good' by all patients on the basis of appearance, taste, smell and texture. All patients found the product 'very easy' to prepare and found it 'easy' or 'very easy' to take outside the home. CONCLUSION All patients thought the preparation of MSUD Express was 'very easy'. Metabolic control (mean leucine concentrations) improved in all of the patients. In three patients this meant that an increase in the amount of natural protein in the diet was possible. All patients elected to stay on MSUD Express after the trial period. MSUD Express appears to be an effective and acceptable product, offering an alternative to current protein substitutes available for older people with MSUD.

Abstract
We have investigated nine patients with cemented Furlong (JRI, London, UK) titanium hip replacements who presented with early pain despite a well-fixed, aseptic prosthesis. All were followed up clinically and radiologically at regular intervals. Pain was located in the thigh and was worse at night. Radiographs showed cortical hypertrophy of the femur around the tip of the stem. Eight of the nine patients subsequently required single-stage revision using an uncemented prosthesis, which relieved the pain. At revision, the pH of the tip of the stem was found to be highly acidic with macroscopic evidence of corrosion consisting of multiple layers of titanium oxides when studied by X-ray dispersive analysis. Cemented titanium implants have a potential for crevice corrosion leading to cortical hypertrophy and intractable pain.

Abstract
Most studies comparing the biomechanical properties of different meniscal repair systems have simply investigated load to failure. Meniscal tissue is highly anisotropic, and far weaker under tension in the radial direction. Radially oriented loading to failure may not therefore be the most physiologically relevant in vitro test for repair of circumferential tears, and determining gapping across repair sites under cyclical loading at lower loads may be of greater importance. Using bovine menisci, vertical circumferential incisions were repaired using a simple vertical 2-0 PDS suture, Meniscal Arrow, Meniscal Fastener or T-Fix. Repairs were tested by simple loading to failure in a materials testing machine, and by cyclic loading between 5 and 10 N for 25 cycles. Initial gapping across the repairs was measured using a digital micrometer, and the increase in gapping under cyclic loading measured using a Differential Voltage Reluctance Transducer. The mean loads to failure for each of the repair groups were: sutures 72.7 N, Arrows 34.2 N, Fasteners 40.8 N and T-Fix 49.1 N. The load to failure was significantly greater with sutures than with Arrows or Fasteners. The mean gapping across the repairs for each of the repair groups after 25 loading cycles were: sutures 3.29 mm, Arrows 2.18 mm, Fasteners 3.99 mm and T-Fix 3.47 mm. The mean gapping was significantly less with Arrows than with Sutures, Fasteners or T-Fix. These results confirm that meniscal repair by suturing gives the highest load to failure, but show that Arrows give superior hold under lower loads, with the least gapping across repairs under cyclic loading of the four methods tested.

Abstract
Although it has been reported, malignant transformation of synovial chondromatosis is rare. We report a case of malignant transformation of synovial chondromatosis in a knee to a low-grade chondrosarcoma, which was treated with synovial excision and total knee replacement. We also present a literature review of the subject. The case illustrates that malignant transformation should be suspected in chronic cases with a sudden exacerbation of symptoms and that interpretation of histology in cartilage lesions is difficult. It also demonstrates that even when guided biopsy techniques are used, the sampling error of a needle biopsy in any large lesion is unavoidable.

Abstract
OBJECTIVE To evaluate the safety and immunogenicity of the recombinant acellular pertussis-diphtheria-tetanus (aPDT) vaccine (C-aPDT, Chiron/Biocine). STUDY DESIGN This is a randomized blinded trial evaluating the safety and immunogenicity of the recombinant aPDT vaccine (C-aPDT, Chiron/Biocine) in 2000 infant recipients compared with 498 controls who received whole cell diphtheria-pertussis-tetanus (wDPT; Connaught) vaccine at 2, 4 and 6 months of age. In addition the safety and immunogenicity of the same C-aPDT vaccine were evaluated as a booster dose in a subset of the same population when given at 15 to 18 months of age and compared with licensed Lederle aPDT vaccine. RESULTS The C-aPDT vaccine was associated with very few local or systemic reactions when compared with wDPT. In toddlers the local and systemic side effects observed were similar after either acellular vaccine. When the immunogenicity of the C-aPDT vaccine was compared with the wDPT (Connaught) in infancy, the vaccines were equivalent for anti-diphtheria response, the wDPT developed higher anti-tetanus response and the C-aPDT vaccine was significantly more immunogenic for all other antigens tested. In toddlers the C-aPDT acellular vaccine exhibited equal or improved immunogenicity for antigens tested as compared with Lederle aPDT except for a higher anti-filamentous hemagglutinin response with the Lederle aPDT vaccine. CONCLUSION The Chiron/Biocine aPDT vaccine offers an improved safety profile as well as improved immunogenicity when compared with a licensed wDPT product.

Abstract
The aim of this study was to investigate the hypothesis that infants at high risk of cerebral palsy would benefit from early physiotherapy. In total, 105 infants with abnormal cranial ultrasound scans were randomized at around term to early physiotherapy or standard treatment (delaying physiotherapy until abnormal physical signs became apparent). At 12 and 30 months there were clinical and objective assessments. Nine infants died and nine were lost to follow-up by 12 months when 87 infants were assessed. One other child had died and three others were lost to follow-up by 30 months when 83 children were assessed. Cerebral palsy was only accurately predicted in 45 (54%) infants. There was no difference in outcome. The difficulty of predicting cerebral palsy reliably and the heterogeneity of the condition should be borne in mind when planning treatment and assessing its efficacy.

Abstract
A screening program for cystic fibrosis (CF) heterozygotes was conducted in a large HMO prenatal population, to evaluate the level of interest among eligible patients, the effectiveness of prescreening education, attitudes toward the screening process, psychological effects, and utilization of prenatal diagnosis and its outcomes. The heterozygote identification rate and frequency of specific CFTR mutations were also assessed. Identified carriers were offered genetic counseling and testing of male partners. Prenatal diagnosis was offered if both parents were identified as carriers. A total of 5,161 women underwent carrier testing; 947 others completed survey instruments only. The acceptance rate of screening was high (78%), and pretest education by videotape was generally effective. Adverse psychological effects were not reported. Participants generally found screening to be desirable and useful. Screening identified 142 female heterozygotes, 109 couples in which the male partner was not a carrier, and 7 high-risk couples. The incidence of R117H mutations was much higher than expected. The number of identified carriers was much lower in Hispanics than in Caucasians. We conclude that large-scale prenatal screening for CF heterozygotes in the absence of a family history of CF is an acceptable method for identifying couples at risk for affected fetuses. Sufficient pretest education can be accomplished efficiently, test insensitivity is well accepted, adverse psychological events are not observed, and general patient satisfaction is high.

Abstract
This study compared three methods of assessing motor impairment during infancy. The 77 infants studied were considered to be at high risk of motor impairment because of abnormal neonatal cranial ultrasound scans or abnormal somatosensory responses. The children were assessed at eight and 12 months post-term by the Movement Assessment of Infants, the Griffiths locomotor development quotient and the limb-by-limb approach, and the results were compared with clinical assessment at 12 months post-term. The sensitivity of the limb-by-limb approach was highest, although its specificity was slightly lower than the other tests. It was also the easiest to perform. While giving information about the quality of movement, none of these methods is a quantitative test of movement.
