Abstract
In a prospective, randomized trial we compared the trochanteric gamma nail (TGN) and the dynamic hip screw (DHS) in the treatment of 146 intertrochanteric fractures. Follow-up was after four and 12 months. The operation time was significantly shorter in the DHS group. At discharge the need for walking aids was less in the DHS group. There were no differences in intraoperative blood loss, medical complications, mortality or length of hospital stay. Major fracture complications occurred twiceas often in the TGN group compared with the DHS group, however they were not statistically significant. Any potential for the TGN leading to a less invasive procedure and a more rapid postoperative mobilisation could not be demonstrated. Compared with the TGN we prefer the DHS for most intertrochanteric fractures in a setting where the majority of these fractures are treated by younger doctors and not by highly specialized hip/trauma surgeons. The TGN may have advantages in selected intertrochanteric fractures.;

Abstract
Entomopathogenic fungi are being used as biocontrol agents of insect pests, but their efficacy can be poor in environments where water availability is reduced. In this study, the potential to improve biocontrol by physiologically manipulating fungal inoculum was investigated. Cultures of Beauveria bassiana, Lecanicillium muscarium, Lecanicillium longisporum, Metarhizium anisopliae and Paecilomyces fumosoroseus were manipulated by growing them under conditions of water stress, which produced conidia with increased concentrations of erythritol. The time-course of germination of conidia at different water activities (water activity, aw) was described using a generalized linear model, and in most cases reducing the water activity of the germination medium delayed the onset of germination without affecting the distribution of germination times. The germination of M. anisopliae, L. muscarium, L. longisporum and P. fumosoroseus was accelerated over a range of aw levels as a result of physiological manipulation. However, the relationship between the effect of physiological manipulation on germination and the osmolyte content of conidia varied according to fungal species. There was a linear relationship between germination rate, expressed as the reciprocal of germination time, and aw of the germination medium, but there was no significant effect of fungal species or physiological manipulation on the aw threshold for germination. In bioassays with M. anisopliae, physiologically manipulated conidia germinated more rapidly on the surface of an insect host, the melon cotton aphid Aphis gossypii, and fungal virulence was increased even when relative humidity was reduced after an initial high period. It is concluded that physiological manipulation may lead to improvements in biocontrol in the field, but choice of fungal species/isolate will be critical. In addition, the population-based threshold model used in this study, which considered germination in terms of physiological time, also called hydrotime, could have general application in mycology and environmental microbiology.

Abstract
OBJECTIVES To describe utilization of antiepileptic drugs (AEDs) in Denmark during 1993-2002, with special emphasis on oxcarbazepine, and to assess probable indications for AED use. MATERIALS AND METHODS We retrieved prescription data from Odense University Pharmacoepidemiological Database, in Funen County, Denmark (population in 2002: 472,869). Within each calendar year we estimated period prevalence, incidence rate and monotherapy rate. Based on co-medication we defined 'epilepsy' when only AEDs were prescribed, 'pain' with co-prescription of opioids, and 'mood disorder' with co-prescription of antipsychotics or antidepressants. RESULTS We identified 15,604 AED users. The prevalence of using AED increased from 9.3 (95% CI, 9-9.5) to 12.1 (11.8-12.4)/1000 persons. The incidence rate increased from 1.4 (1.3-1.6) to 1.7 (1.6-1.9)/1000 personyears. The monotherapy rate was 79-82%. AED use for 'epilepsy' declined by 19.7%, whereas the proportion of 'pain' and 'mood disorder' treatment increased by 11.2% and 8.4% respectively. CONCLUSIONS Antiepileptic drug utilization increased during the study period, the increase probably caused by expanding use in areas other than epilepsy.

Abstract
The aetiology of congenital club foot is unclear. Although studies on populations, families and twins suggest a genetic component, the mode of inheritance does not comply with distinctive patterns. The Odense-based Danish Twin Registry contains data on all 73 000 twin pairs born in Denmark over the last 130 years. In 2002 all 46 418 twins born between 1931 and 1982 received a 17-page questionnaire, one question of which was ‘Were you born with club foot?’ A total of 94 twins answered ‘Yes’, giving an overall self-reported prevalence of congenital club foot of 0.0027 (95% confidence interval (CI) 0.0022 to 0.0034). We identified 55 complete twin pairs, representing 12 monozygotic, 22 dizygotic same sex (DZss), 18 dizygotic other sex (DZos) and three unclassified. Two monozygotic and 2 DZss pairs were concordant. The pairwise concordance was 0.17 (95% CI 0.02 to 0.48) for monozygotic, 0.09 (95% CI 0.01 to 0.32) for DZss and 0.05 (95% CI 0.006 to 0.18) for all dizygotic (DZtot) twins. We have found evidence of a genetic component in congenital club foot, although non-genetic factors must play a predominant role.

Abstract
OBJECTIVE To assess the prevalence of overweight, obesity and physical inactivity in 20- to 29-year-old men and to analyze whether sociodemography, physical dysfunction and low socioeconomic status are independent correlates of obesity and physical inactivity. DESIGN Population-based, cross-sectional study. SUBJECTS Seven hundred and eighty-three Caucasian, Danish men, aged 20-29 years recruited from 2042 respondents in a questionnaire survey of 3000 men, randomly drawn from the Danish Civil Registration System. METHODS Questionnaire, interview and physical examination. RESULTS The 783 included men and the 2042 questionnaire respondents matched the background population demographically. The 783 men matched the questionnaire respondents as regards BMI, physical activity, chronic disease, medication, smoking, sociodemography and socioeconomic status. The prevalence of overweight and obesity was 31.7 and 7.9%, respectively (World Health Organization criteria). Using waist circumference (WC) cutoffs of 94 and 102 cm, the prevalence was 16.2 and 10.6%, respectively; 24.4% were physically inactive. BMI and WC increased significantly from age 20 to 29 years. Physical activity decreased significantly with age and correlated inversely with WC, but not with BMI. Occupation, geography, partner status, fatherhood and tobacco exposure were independently related with obesity and physical inactivity. Obesity was also related to musculoskeletal complaints, whereas chronic diseases and low educational level were associated with physical inactivity. Age was not independently related with either outcome. CONCLUSION In affluent societies, sociodemographic changes may partly explain the age-related decrease in physical activity and the parallel increase in WC and BMI.

Abstract
This review provides a framework contributing to the risk assessment of acrylamide in food. It is based on the outcome of the ILSI Europe FOSIE process, a risk assessment framework for chemicals in foods and adds to the overall framework by focusing especially on exposure assessment and internal dose assessment of acrylamide in food. Since the finding that acrylamide is formed in food during heat processing and preparation of food, much effort has been (and still is being) put into understanding its mechanism of formation, on developing analytical methods and determination of levels in food, and on evaluation of its toxicity and potential toxicity and potential human health consequences. Although several exposure estimations have been proposed, a systematic review of key information relevant to exposure assessment is currently lacking. The European and North American branches of the International Life Sciences Institute, ILSI, discussed critical aspects of exposure assessment, parameters influencing the outcome of exposure assessment and summarised data relevant to the acrylamide exposure assessment to aid the risk characterisation process. This paper reviews the data on acrylamide levels in food including its formation and analytical methods, the determination of human consumption patterns, dietary intake of the general population, estimation of maximum intake levels and identification of groups of potentially high intakes. Possible options and consequences of mitigation efforts to reduce exposure are discussed. Furthermore the association of intake levels with biomarkers of exposure and internal dose, considering aspects of bioavailability, is reviewed, and a physiologically-based toxicokinetic (PBTK) model is described that provides a good description of the kinetics of acrylamide in the rat. Each of the sections concludes with a summary of remaining gaps and uncertainties.

Abstract
OBJECTIVE To investigate whether elevated ACTH-stimulated 17-hydroxyprogesterone (17OHP) levels are caused by CYP21 genetic defects or by a general adrenal hyperresponsiveness in hirsute patients. METHODS A total of 337 hirsute patients were evaluated by Ferriman-Gallwey score, serum testosterone, ACTH-stimulated 17OHP, and cortisol during the follicular phase. A cutoff value of 16 nmol/liter for maximum ACTH-stimulated 17OHP (M17OHP) responses was defined as the upper limit of the 95% confidence interval (CI) for the 97.5 percentile in 42 female controls. All patients were offered total screening of the CYP21 gene, and 252 healthy, premenopausal women with regular menses underwent genetic screening. RESULTS Patients were divided into idiopathic hirsutism (IH) (n = 180) and polycystic ovary syndrome (PCOS) (n = 157) groups. M17OHP levels were significantly higher in IH [geometric mean value (nmol/liter +/- 2 sd) 12.2 (4.6-32.3)] and PCOS [11.9 (5.3-27.2)] compared with controls [8.5 (5.1-14.2)] (P < 0.001). A similar percentage of IH and PCOS patients had elevated M17OHP (20.5 vs. 20.8%, not significant), and these also had significantly higher 30-min cortisol levels compared with controls (P < 0.05). The prevalence of CYP21 mutations in patients was 8.6% compared with 6.3% in controls (P = 0.38). Ten of 19 carriers had M17OHP levels below the cutoff limit. CONCLUSION The significantly higher ACTH-stimulated levels of cortisol and 17OHP in hirsute patients indicated adrenal hyperresponsiveness in IH and PCOS. CYP21-carrier status could not explain the observed high prevalence of abnormal ACTH-stimulated 17OHP levels in the hirsute population.

Abstract
PURPOSE To determine reference values for vertebral heights in healthy young Danish males using morphometric X-ray absorptiometry (MXA). MATERIAL AND METHODS A population-based study group of 487 males aged between 20 and 30 years (mean 25 years) from the county of Funen, Denmark, were recruited. Using a Hologic QDR 4500 (dual energy X-ray absorptiometry) DXA-scanner, MXA scans covering the vertebrae from T4 to L4 were acquired for each subject. Anterior (Ha), middle (Hm), and posterior (Hp) heights of the thoracic (T4-T12) and lumbar (L1-L4) vertebral bodies were measured. Moreover, wedge, mid-wedge, crush I, and crush II ratios were calculated. RESULTS No correlation between vertebral dimensions and crush indices on the one hand and age or weight on the other were found. Body height, however, correlated significantly with the cumulated vertebral heights. Reference data for vertebral dimensions, wedge, mid-wedge, crush I, and crush II are tabulated. CONCLUSION The anterior, middle, and posterior heights of the vertebral bodies of T4 to L4 can be measured reproducible with MXA. In young men, the cumulative vertebral heights correlated with body height but not with age. Moreover, the wedge and crush indices were unrelated of both age and height.

Abstract
Incisional local anaesthesia is widely used for postoperative pain relief after surgery. We present the results of a double-blinded and randomised controlled study of incisional bupivacaine versus placebo in 68 children undergoing open appendectomy. The trial medicine (0.5 ml/kg) was infiltrated into the subcutis after wound closure. Patients with a weight below 40 kg received a bupivacaine concentration of 0.25 % and the patients above 40 kg a concentration of 0.5 %. During the first 24 hours after surgery the patients in the bupivacaine group received on average 0.065 mg morphine/kg and in the placebo group 0.073 mg/kg. This difference was not statistically significant. The patients in the bupivacaine group tended to experience pain relief for a longer period of time compared to the patients in the placebo group. However, the difference was not significant. In conclusion, the use of subcutaneous infiltration with bupivacaine in the wound after open appendectomy had no significant effect on the use of morphine during the first postoperative day in children.

Abstract
The purpose of this Grounded Theory based study was to add to the limited understanding about the perception and observation of pain by the formal and informal carers of people with dementia. Thirty-one carers talked about how they know when their person with dementia has pain. Findings showed there is no one set of signs or behaviours that indicate pain in all people with dementia. However, a common pain assessment process amongst carers involved being able to detect deviation from normal behaviours based upon their intimate knowledge of what is normal for their person. A central hypothesis was thus generated from the data that considered that effective pain assessment for people with dementia is dependent on carers having an intimate knowledge of the individual's normal state of being with dementia. Implications for nursing practice are discussed.

Abstract
There has been an increase in the demand for allograft bone in recent years. The Odense University Hospital bone bank has been in function since 1990, and this paper outlines our results during the 10 year period 1990-1999. Potential donors were screened by contemporary banking techniques which include a social history, donor serum tests for HIV, hepatitis B and C, and graft microbiology. The bones were stored at -80 degrees C. No type of secondary sterilisation was made. 423 femoral heads were approved and donated to 300 patients,1-6 heads/operation. The allografts have been used mainly to reconstruct defects at revision hip arthroplasty (34%), and for fracture surgery (24%). 7 % of all transplanted patients were reoperated because of infection. In the hip revision group the infection rate was 4 %. There were no cases of disease transmission. During the 10 year period there was a change in the clinical use of the allografts. In the first years the allografts were mainly used for spinal fusion surgery, but today the majority are used in hip revision and fracture surgery. The clinical results correspond to those reported in larger international series.

Abstract
OBJECTIVE Patients with GH deficiency of adult onset (GHDA) exhibit dyslipidaemia and increased cardiovascular morbidity. GH replacement potently reduces body fat and serum lipids in GHDA. In recent years, lower GH doses have been introduced. The purpose of this analysis was to explore the response relationship between GH doses, lipids and body composition. DESIGN Two consecutive, randomized 12-month GH replacement studies covering placebo and three different doses of GH (0.5, 1.0 and 1.7 IU/m(2) per day). Low and intermediate doses were IGF-I titrated. PATIENTS Fifty-eight patients with severe GHDA, not previously treated with GH and stably substituted for other endocrine deficiencies, were included in the study. METHODS Serum lipoproteins, serum IGF-I and body composition analysis by dual energy X-ray absorptiometry (DXA) were used. RESULTS Fifty-seven percent of patients exhibited low density lipoprotein (LDL) cholesterol levels above 4.16 mmol/l, corresponding to the American Heart Association threshold of 160 mg/dl. GH treatment resulted in significant decreases in total and LDL cholesterol, with no significant change in high density lipoprotein cholesterol or triglycerides. The low dose induced no significant changes in lipid levels, whereas the medium dose reduced LDL cholesterol and the high dose decreased both LDL and total cholesterol. The effects depended significantly on the GH dose and the level of IGF-I obtained, but not on gender. GH replacement induced dose-dependent reductions in fat mass and sex-dependent increases in lean mass. CONCLUSIONS GH given for 1 year at a dosage between 0.5 and 1.7 IU/m(2) per day reduced fat mass in a dose-dependent manner, increased lean body mass and lowered total and LDL cholesterol in patients with severe GHDA. Low dose GH treatment with normal IGF-I levels induced smaller changes compared with high dose therapy, and may need a longer treatment time.

Abstract
The World Federation of Societies of Biological Psychiatry guidelines for treatment of unipolar major depression has recommended three depression rating scales for evaluating outcome: The Hamilton Depression Rating Scale (HAM-D), the Montgomery-Asberg Depression Rating Scale (MADRS), and the Bech-Rafaelsen Melancholia Scale (MES). In this study we evaluated the ability of these scales to differentiate between citalopram and placebo in the recurrence prevention of unipolar depression. The study is a psychometric reexamination of a trial on the efficacy of citalopram versus placebo in the maintenance therapy of elderly patients with unipolar depression. Internal validity (the Cronbach coefficient alpha, the Loevinger coefficient of homogeneity, and factor analysis) of the three scales has been examined to evaluate their unidimensionality. In the outcome analysis for depression recurrence, the conventional cutoff scores of the three scales are used. In total, 60 patients received citalopram and 61 patients received placebo in the maintenance phase of 48 weeks. The results showed that the internal validity was higher for MES and MADRS than for HAM-D. Using the MADRS, 67.2 % of the patients on placebo and 31.6 % of the patients on citalopram developed a depression recurrence (ratio 2.12); using HAM-D17, 42.6 % on placebo and 13.3 % on citalopram developed a depression recurrence (ratio 3.20); and using the MES, 34.4 % on placebo and 11.7 % on citalopram developed a depression recurrence (ratio 2.94). The conventional cutoff scores of HAM-D17 and MES for depression recurrence indicated a ratio between citalopram and placebo of around 3, while the conventional cutoff scores of MADRS for depression recurrence indicated a ratio of only around 2. In future trials on the recurrence prevention of unipolar depression, a cutoff score of 25 rather than 22 on the MADRS is recommended.

Abstract
The aim of this paper was to describe a method for the preparation of autologous fibrin glue with platelet growth factors and to report its use with particulate cancellous bone in reconstructive maxillofacial surgery. The fibrin glue is a two-component glue, where the one component is a concentrated fibrinogen solution with platelet growth factors and the other component is a thrombin solution. Both components were produced from the patients own blood, thus making the glue entirely autologous. The glue was prepared from platelet rich plasma separated from 200 ml of the patient's blood prior to the operation. The fibrinogen in the glue was precipitated from the platelet rich plasma by ethanol precipitation at low temperature and separated together with the platelets by centrifugation. Raising the temperature to 37 degrees C redissolved the precipitate. The thrombin solution in the glue was produced from prothrombin precipitated from 10 ml of the platelet rich plasma by lowering the pH and the ionic strength. The precipitate was separated by centrifugation and dissolved in a calcium ion solution. Increasing the pH to neutral value induced activation to thrombin. Preparation of the fibrin glue was performed in the blood bank within 60 to 90 min with the use of standard equipment. The outcome from 200 ml of blood was approximately 8 ml of fibrin glue: 6 ml fibrinogen to be coagulated with 2 ml of thrombin. The glue had a fibrinogen concentration of approximately 12 times the value in platelet rich plasma and the concentration of growth factors was approximately eight times the value in platelet rich plasma. We have used this glue successfully with particulate bone grafts for reconstructive purposes within the oral and maxillofacial field. It might as well be applied to other surgical areas. Whenever larger amount of the glue will be needed, a whole unit of blood may be taken from the patient, and the red cells re-transfused to the patient during or after the operation.
