Authors: HAAKSTAD LENE A.H. , VOLDNER NANNA , HENRIKSEN TORE , BØ KARI 
Published: May 2007

AbstractBackground. It is generally recommended that healthy, pregnant women should engage in moderate exercise on most days of the week. However, there is scant knowledge about the overall physical activity and exercise levels among pregnant women. Purpose. To assess the total physical activity level of pregnant women, and to investigate the association between weight gain, physical activity and exercise during pregnancy. Methods. Pregnant women (n = 467) answered a questionnaire on total physical activity level in gestation week 36. Results. Some 55% of the participants reported working in a sitting position. Most women drove (52.9%) or used public transport (31.7%) to work. A total of 39% reported sedentary activities of ≥4 h (watching television and reading) daily; 19% were defined as non‐exercisers before pregnancy, 30% in the first trimester, 36% in the second trimester and 53% in the third trimester. Fifty women (10.6%) continued to exercise ≥4 times/week in the third trimester. Mean weight gain was 13.8 kg (SD: 5.2). Of the normal pregestational weight women (pre‐BMI: <26) and overweight women (pre‐BMI: ≥26), 32 and 51% had exceeded weight gain above accepted recommendations, respectively. Women who exercised regularly had significantly lower weight gain than inactive women in the third trimester only. Conclusion. Pregnant women have a low total physical activity level, and a high percentage of women exceed the recommended weight gain during pregnancy.

Authors: ANDERSSON SONIA , MINTS MIRIAM 
Published: May 2007

AbstractBackground. Excessive menstrual bleeding, menorrhagia, is a common gynecological problem in women of reproductive age. Since 1994, thermal balloon ablation has become the treatment of choice for women with menorrhagia. The aim of this study was to evaluate the short‐ and long‐term results of thermal balloon ablation for the treatment of menorrhagia in an outpatient setting. Methods. Fifty‐six women with menorrhagia had undergone a balloon ablation in an outpatient setting at the Gynecological Departments at Karolinska University Hospital, Huddinge. At follow‐up, all of the women were requested to complete a questionnaire concerning bleeding patterns, the degree of dysmenorrhea, side effects, or a need for further therapy after balloon ablation. Results. Thermal balloon ablation was successfully completed in 54 (97%) women. The two unsuccessful procedures consisted of one case, in which the woman had an allergic reaction to a paracervical block, and another case in which the balloon catheter could not be inserted into the uterine cavity. In three cases, short‐term complications occurred: an allergic reaction to a paracervical block, endometritis, and abdominal cramps. Completed outcome questionnaires were submitted by 42 (75%) of the women. The mean follow‐up period was 31 months. A reduction of menorrhagia was experienced by 34 (81%) of the women. One woman had undergone a hysterectomy and three had a hysteroscopical endometrial resection within two years after the ablation due to persistent menorrhagia. Conclusion. Thermal endometrial ablation is a safe and effective treatment for menorrhagia and is feasible in an outpatient setting.

Published: May 2007

AbstractBackground. Estimate the frequency of failure to follow the French consensus guidelines for elective induction, and assess how failure affects the rate of cesarean delivery. Methods. We compared cesarean rates according to mode of onset of labor among 5,046 low‐risk patients. Violation of the guidelines was defined as induction before 38 weeks or with a Bishop score <5 or with prostaglandins. The cesarean risk was analysed with a bivariable and then a multivariable analysis, which used a multilevel logistic model. Results. Women with electively induced and spontaneous labor had identical cesarean rates (4.1%). The guidelines were not followed in 23.2% of elective inductions. The risk of cesarean was higher after induction with a Bishop score <5, than after spontaneous labor (adjusted OR = 4.1, 95% CI [1.3–12.9]), while elective induction with a favourable cervix did not increase the cesarean risk. In nulliparas, failure to follow the guidelines tripled the risk of cesarean (adjusted OR = 3.2 [1.0–10.2]). On the other hand, elective induction of labor for women with a favourable cervix did not increase the risk of cesarean over the risk with spontaneous labor. Conclusion. Elective induction does not appear to increase the cesarean rate when the guidelines are met. Electively inducing labor with a low Bishop score increased the risk of cesarean, especially in nulliparas.

Published: May 2007

AbstractBackground. Polycystic ovary syndrome (PCOS) is accompanied by selective insulin resistance and enhanced ovarian steroidogenic effects of insulin. We analysed the minisatellite variations of the insulin gene (INS VNTR) with regard to the clinical features of PCOS. Methods. Retrospective, adjusted association study. Infertile patients with PCOS (n = 30) and tubal factor (n = 75) were screened for anthropometrical, clinical and ovarian morphology parameters, as well as hormonal values. INS VNTR was genotyped by its surrogate marker at −23 HphI locus. Results. INS VNTR genotype distribution was similar in PCOS and tubal infertility group. The mean ovarian follicle number was higher in VNTR I/I individuals compared to VNTR I/III and III/III individuals (adjusted OR = 1.28, p = 0.03), independent from the cause of infertility, the age, the follicle stimulating hormone level on day 3–5 of menstrual cycle, BMI and the previous surgical ovarian tissue removal. In addition, higher level of the luteinising hormone in VNTR I/I individuals was associated with the increase in follicle number. Conclusions. We suggest that INS VNTR genotypes are not associated with PCOS in general, but could have a certain influence on the phenotypic spectrum of the syndrome.
CAOS Contribution to Understanding Cultural/Ethnic Differences in the Prevalence of Bipolar Affective Disorder in New Zealand
Authors: Mellsop Graham , Dutu Gaelle , El-Badri Selim 
Published: May 2007

Objective: To examine whether data on the clinical profiles of psychiatric service users can inform the claim that Maori in the New Zealand community have an increased rate of bipolar disorder. Method: The standardized recordings of a variety of clinical phenomena previously collected in a New Zealand study of psychiatric service users was extracted for those persons who were diagnosed with a bipolar mental disorder. The individual clinical phenomena were then compared by ethnicity. Results: The most dramatic result was the increased recording of high levels of overactivity or disruptive aggressive behaviour in Maori compared with European in psychiatric service users, despite which, the rates of the disorder did not significantly differ by ethnicity. Conclusion: In the community survey lay raters were deciding on the presence or absence of phenomena including hyperactivity without the contextual knowledge that clinicians use. It is possible that the Composite International Diagnostic Interview decision tree was being fed an excessive amount of that criterion.
Assessing the Impact of Media Guidelines for Reporting on Suicides in Austria: Interrupted time Series Analysis
Authors: Niederkrotenthaler Thomas , Sonneck Gernot 
Published: May 2007

Objective: Media guidelines for reporting on suicides are a widely used means of preventing imitative suicides, but scientific accounts of their impact on suicide numbers are sparse. This report provides an evaluation of the Austrian guidelines that were introduced in 1987 as a natural experiment. Methods: The impact of the guidelines was tested by applying an autoregressive integrated moving average (ARIMA) model and a linear regression model. In addition to a nationwide evaluation, Austria was divided into three areas according to regional differences in coverage rates of the collaborating newspapers and the impact of the intervention was tested for each area separately. Main outcome measures were the overall annual suicide numbers, and the numbers of Viennese subway suicides that were exceptionally newsworthy for the mass media. In order to test intermediate impacts, also quantitative and qualitative changes in media reporting after the introduction of the guidelines were analysed. Results: There was some evidence of a nationwide impact of the guidelines, calculated as a significant reduction of 81 suicides (95% confidence interval: −149 to −13; t = −2.32, df = 54, p <0.024) annually. This effect was particularly due to a significant reduction in the area with the highest coverage rates of the collaborating newspapers. Viennese subway suicides showed a highly significant level shift (t = −4.44, df = 19, p <0.001) and a highly significant trend change (t = −4.20, df = 19, p <0.001) after the introduction of the guidelines. These effects corresponded to significant changes in the quality and quantity of media reporting. Conclusions: The present results clearly support the hypothesis that the media guidelines have had an impact on the quality of reporting as well as on suicidal behaviour in Austria, and stress the importance of collaborating with nationwide, but also with regional media to achieve efficacy. Further research is needed to provide an international insight into this public health issue.
Multidetector computed tomography imaging of facial trauma in accidental falls from heights
Authors: Salonen E. M. , Koivikko M. P. , Koskinen S. K. 
Published: May 2007

Purpose: To assess multidetector computed tomography (MDCT) findings in facial trauma in adults who accidentally fall from heights. Material and Methods: Of the MDCT scans of 2413 cases requested by emergency-room physicians for suspected facial injury, 155 (age 15.3–76.7, mean 42.0 years; 134 male, 21 female) met the criteria of falling from heights. These were reviewed by two researchers by consensus. Results: Of these 155, 118 (104 male, 14 female) had 247 fractures, while 37 had no fracture. The fractures were classified into 13 categories, the zygomatic complex being the region most frequently involved. Mean falling height, known in 132 of 155 cases, was 5.7 m (range 0.4–25) in all, 6.0 m (0.4–25) in those suffering a fracture, and 5.0 m (range 0.4–13) in those without a fracture. Patients with Le Fort II, Le Fort III, or frontal bone fractures had fallen higher and frequently had associated skull base fractures, but with considerable overlap in falling heights. Zygomatic arch and nasal bone fractures rarely occurred solitarily. Conclusion: In a fall-from-height injury, nasal bone and zygomatic arch fractures indicate the presence of more severe fractures. Height cannot solely predict injury probability. Clear sinus sign is a valuable aid in assessing midface trauma in falls from heights.
Do contrast media (iomeprol, gadopentetate dimeglumine) deteriorate ischemia/reperfusion injury of the liver?
Authors: Demir R. , Banafsche R. , Melling N. , Gebhard M. -M. , Klar E. 
Published: May 2007

Background: Hepatic microcirculation is a main determinant of reperfusion injury and graft quality in liver transplantation. One of the important diagnostic procedures to recognize reperfusion failure is contrast-enhanced computed tomography or magnetic resonance imaging. Purpose: To examine the additional effect of contrast media (iomeprol and gadopentetate dimeglumine) on hepatic microcirculation and hepatic cellular damage in the phase of early ischemia/reperfusion injury of the rat liver. Material and Methods: The partial warm ischemia-reperfusion injury model of rat liver was used. Microcirculation and leukocyte–endothelium interaction were measured by intravital microscopy. Hepatic cellular damage was indicated by liver enzyme activity in the sera. The evaluation parameters were measured at baseline and at 30, 60, and 90 min after reperfusion. The contrast media (iomeprol group, n = 6; gadopentetate dimeglumine group, n = 6) or Ringer's solution (control group, n = 8) were applied after 30 min of reperfusion. Results: No additional injury to the ischemia/reperfusion injury of the liver after intravenous application of radiographic contrast media was found. Some protective effect was even recorded after application of iodinated contrast media. Conclusion: The use of contrast media during diagnostic procedure of the liver seems to be relatively safe, even in the stage of early reperfusion after liver transplantation.

Published: May 2007

Purpose: To evaluate the appearance, type, frequency, and clinical importance of retroaortic left renal vein (RLRV) in patients examined with multidetector computed tomography (MDCT) angiography. Material and Methods: A total of 1856 patients who underwent CT with urological symptoms (hematuria, flank and abdominal pain, left gonadal vein varicocele) ( n = 889) or with symptoms other than urological ones ( n = 967) were prospectively evaluated for the presence of RLRV. CT was performed with 110 ml of iodinated contrast material through the antecubital vein at a rate of 3.5 ml/s. Late arterial and early venous phase volumetric data sets were acquired at 30 and 65 s, respectively, from the start of the intravenous injection of contrast medium. In addition to axial images, multiplanar reconstructions (MPR), maximum-intensity projection (MIP), and three-dimensional volume-rendering (3D VR) images were used to assess left renal vein anomalies. Left renal vein anomalies were classified into four types according to their appearance: I) RLRV joining the inferior vena cava (IVC) in the orthotopic position; II) RLRV joining the IVC at level L4–L5; III) circumaortic or collar left renal vein; IV) RLRV joining the left common iliac vein. Results: RLRV was detected in 68 (3.6%) of the 1856 patients, with 26, 22, 17, and three of types I, II, III, and IV, respectively. Forty-four of the 68 patients with RLRV (65%) were in the group with urological symptoms, while 24 patients (35%) were in the group without urological symptoms. Compression of the RLRV was found in 16 patients in the urological symptoms group, while compression was detected in only three patients in the other group. This difference was statistically significant ( P<0.05). The most common urological symptom was hematuria. The frequency of urological symptoms was higher in groups II and IV compared to the other groups. Conclusion: MDCT angiography with axial, MPR, MIP, and 3D VR images is effective in the detection of vascular renal anomalies such as RLRV. Diagnosing RLRV and differentiating it from other pathologic conditions causing hematuria is important in order to avoid complications during retroperitoneal surgery or interventional procedures.
Gadolinium contrast agent is of limited value for magnetic resonance imaging assessment of synovial hypertrophy in hemophiliacs

Published: May 2007

Purpose: To examine the influence of different doses of gadolinium contrast agent on synovial enhancement, to compare magnetic resonance imaging (MRI) findings of synovial hypertrophy and radiographic joint changes in hemophiliacs, and to investigate the value of gadolinium in MRI assessment of synovial hypertrophy in hemophiliacs using dynamic MRI and MRI scoring. Material and Methods: Twenty-one hemophiliacs on prophylactic factor treatment without recent bleeds were subjected to radiography and gadolinium contrast-enhanced dynamic and static MRI of the knee using a standard dose of 0.1 mmol/kg b.w. gadoteridol. In 17 of the patients, the MRI procedure was repeated after a triple dose of gadoteridol. Results: MRI findings of synovial hypertrophy were significantly correlated with Pettersson radiographic scores. In 19 of the 21 MRI investigated joints, administration of contrast agent did not alter the result of the evaluation of synovial hypertrophy. Conclusion: The optimal time interval for volume assessment of synovial hypertrophy after injection of gadolinium contrast agent is dose dependent. Hemophiliacs without recent bleeds have minor to abundant synovial hypertrophy in joints with pronounced radiographic changes. Dynamic MRI is not useful for evaluating hemophilic arthropathy, and gadolinium contrast agent is not routinely indicated for MRI scoring of joints in hemophiliacs.
Endovascular coiling of intracranial aneurysms using bioactive coils: a single-center study
Authors: Rossitti S. 
Published: May 2007

Background: Some degree of recanalization is reported in up to one-third of intracranial aneurysms treated with endovascular coiling. A technical development potentially effective in avoiding recanalization is the Matrix Detachable Coil (MDC), which is covered with a biodegradable polymeric material that enhances intra-aneurysmal clot organization and fibrosis. Purpose: To report the initial clinical experience of MDC for endovascular aneurysm coiling in a single-center, single-operator, and well-defined population setting. Material and Methods: 118 aneurysms in 104 patients (73 with subarachnoid hemorrhage, SAH) were embolized with MDC alone ( n = 52) or combined with bare platinum coils ( n = 66). Results: Initial aneurysm obliteration was class 1 (complete obliteration) in 45 aneurysms (38.1%), class 2 (residual neck) in 44 (37.3%), and class 3 (residual aneurysm) in 29 (24.6%). Procedure-related morbidity was 4.8%, and mortality 0.96%. Clinical follow-up of 61 patients with SAH (mean 5.9 months, range 1–17 months) showed good outcome (Glasgow Outcome Scale, GOS 4–5) in 39 (63.9%), and poor outcome or death (GOS 1–3) in 22 (36.1%). Imaging follow-up of 73 aneurysms (average 6.5 months, range 1–17 months) showed class 1 in 47 (64.4%), class 2 in 18 (24.7%), and class 3 in eight (10.9%). Recanalization occurred in 11 aneurysms (15%), of which four (5.5%) required re-treatment. Conclusion: This study confirms that aneurysm coiling with MDC is feasible, effective, and safe.

Abnstract
Management research has received little attention in the sociology of science. This qualitative survey explains the limited participation of French scholars in the international academic journals of management. The theoretical framework is social cognition. This paper focuses on the categorisation process and relevant attributes. Final discussion suggests new research avenues concerning categorisation automaticity, variability of attribute effect, mediation process, and category inhibition.
Can We Make Sense of Knowledge Management’s Tangible Rainbow? A Radical Constructivist Alternative
Authors: Ray Tim , Clegg Stewart 
Published: May 2007

Abstract
Nonaka and Takeuchi’s highly influential account of tacit–explicit knowledge‐conversion in Japan’s knowledge‐creating companies has been instrumental in Knowledge Management’s institutionalisation of Michael Polanyi’s distinction between ‘tacit knowledge’ and ‘explicit knowledge’. But tacit knowledge has been misunderstood and what Nonaka and Takeuchi claim in the name of explicit knowledge does not make sense. Whereas Polanyi was concerned with the discovery of absolute truth about ontological reality, Nonaka and his colleagues insist that truth is ‘in the eye of the beholder’. Yet, Nonaka et al.’s implicit nihilism seems to have gone unnoticed. Many people talk about explicit knowledge as if it existed on a par with scientific knowledge: a tangible commodity that is ‘as real as rocks’. Arguably, Nonaka and Takeuchi have offered a ‘lesson from Japan’ that has distorted Polanyi’s concept of tacit knowing, inspired unwarranted faith in the viability of ‘explicit knowledge’, and ignored the significance of power mediated by ‘high‐context’ communication. This paper uses Ernst von Glasersfeld’s work on radical constructivism to make sense of Polanyi’s insights into tacit knowing without invoking notions of metaphysical truth. With reference to knowing, learning and communicating in Japanese organisations, we suggest that a radical constructivist approach offers a viable alternative to Nonaka and Takeuchi’s knowledge‐conversion model.

Published: May 2007

AbstractAmongst people on opioid maintenance treatment (OMT), chronic hepatitis C (HCV) is common but infrequently treated. Numerous barriers, including misuse of alcohol may limit efforts at anti‐viral treatment. The aim of this study was to define barriers, including alcohol misuse, to the effective treatment of HCV amongst OMT recipients. Ninety‐four OMT patients completed the 3‐item Alcohol Use Disorders Identification Test (AUDIT‐C). A semi‐structured interview was used in 53 subjects to assess alcohol use in detail, psychological health, discrimination and access to HCV treatment. Feasibility of brief intervention for alcohol misuse was assessed. Of the screening participants, 73% reported they were HCV positive. Of the detailed interview participants, 26% reported no drinking in the past month, but 53% scored 8 or more on AUDIT and 42% exceeded NHMRC drinking guidelines. Twenty subjects received brief intervention and among 17 re‐interviewed at one month, alcohol consumption fell by 3.1 g/day (p = 0.003). Severe or extremely severe depression, stress and anxiety were found in 57%, 51% and 40% of interviewees respectively. Episodic heavy drinking, mental health problems, perceived discrimination, limited knowledge concerning HCV were all common and uptake of HCV treatment was poor. Brief intervention for alcohol use problems was acceptable to OMT patients, and warrants further study.
Mentoring Young Researchers: Can the Donald J Cohen Fellowships Model be Applicable and useful to Australasian Psychiatry?

Published: May 2007

Objectives: To describe the experience with the Donald J Cohen Fellowship program of the International Association for Child and Adolescent Psychiatry and Allied Professions (IACAPAP) and examine whether this model may be applied by the RANZCP to attract and support young researchers in Australasia. Methods: The program at the September 2006 IACAPAP conference included 50 young researchers, 16 mentors and 8 ‘host fellows’, and consisted of exclusive poster sessions, daily small-group mentoring meetings, oral presentation of selected papers, and a summary and feedback session. Results: Informal feedback from mentors, mentees and conference organisers was very positive. Conclusions: A proposal about funding, participants and activities is presented. This suggests that a mentoring model similar to the Donald J Cohen Fellowship program can be easily conducted in Australasia. Implementing a program of this type would give College Fellows, the Australian Medical Council, the Commonwealth Government and other relevant organizations a clear message that the RANZCP is seriously committed to fostering and supporting research.
