The effectiveness and cost-effectiveness of microwave and thermal balloon endometrial ablation for heavy menstrual bleeding: a systematic review and economic modelling.

OBJECTIVES: To estimate the clinical effectiveness and cost-effectiveness of microwave endometrial ablation (MEA) and thermal balloon endometrial ablation (TBEA) for heavy menstrual bleeding (HMB), compared with the existing (first-generation) endometrial ablation (EA) techniques of transcervical resection (TCRE) and rollerball (RB) ablation, and hysterectomy. DATA SOURCES: Electronic databases, bibliographies of articles, and also experts in the field and relevant industry bodies were asked to provide information. REVIEW METHODS: A detailed search strategy was carried out to identify systematic reviews and controlled trials of MEA and TBEA versus first-generation techniques for EA. In addition to electronic database searching, reference lists were hand-searched and information sought from manufacturers of EA devices and by experts in the field. A deterministic Markov model was developed to assess cost-effectiveness. Data for the model were taken from a range of sources. RESULTS: The systematic review of first-generation EA techniques versus hysterectomy found that EA offered an alternative to hysterectomy for HMB, with fewer complications and a shorter recovery period. Satisfaction and effectiveness were high for both MEA and TBEA. Costs were lower with EA although the difference narrows over time. Second-generation EA techniques are an alternative treatment to first-generation techniques for HMB, and first-generation techniques are known to offer an alternative to hysterectomy. Although no trials of second-generation techniques and hysterectomy have been undertaken, it seems reasonable to assume that second-generation techniques also offer an alternative surgical treatment. Using the model to assess cost-effectiveness, costs were very slightly higher for MEA when compared to TBEA, and differences in quality-adjusted life-years (QALYs) were negligible. For MEA compared with transcervical resection of the endometrium (TCRE) and RB ablation, costs were slightly lower with MEA and MEA accrued very slightly more QALYs. Compared with hysterectomy, MEA costs less and accrues slightly fewer QALYs. For TBEA compared with TCRE and RB ablation, costs were lower with TBEA and TBEA accrued slightly more QALYs. Compared with hysterectomy, TBEA costs moderately less and accrues moderately fewer QALYs. CONCLUSIONS: Overall, there were few significant differences between the outcomes of first- and second-generation techniques including bleeding, satisfaction and QoL measures and repeat surgery rates. Second-generation techniques had significantly shorter operating and theatre times and there appear to be fewer serious perioperative adverse effects with second-generation techniques and postoperative effects are similar. Compared with hysterectomy, TCRE and RB are quicker to perform and result in shorter hospitalisation and faster return to work. Hysterectomy results in more adverse effects and is more expensive, although the need for retreatment leads this difference to decrease over time. Satisfaction with hysterectomy is initially higher, but there is no significant difference after 2 years. The economic model suggests that second-generation techniques are more cost-effective than first-generation techniques of EA for HMB. Both TBEA and MEA appear to be less costly than hysterectomy, although the latter results in more QALYs. Further research is suggested to make direct comparisons of the cost-effectiveness of second-generation EA techniques, to carry out longer term follow-up for all methods of EA in RCTs, and to develop more sophisticated modelling studies. Further research is also recommended into HMB to establish health-state utility values, its surgical treatment, convalescence, complications of treatment, symptoms and patient satisfaction.

A systematic review and economic evaluation of magnetic resonance cholangiopancreatography compared with diagnostic endoscopic retrograde cholangiopancreatography.

OBJECTIVES: To compare the clinical and cost-effectiveness of magnetic resonance cholangiopancreatography (MRCP) with diagnostic endoscopic retrograde cholangiopancreatography (ERCP) for the investigation of biliary obstruction. DATA SOURCES: Electronic bibliographic databases, the reference lists of relevant articles and various health services research-related resources. REVIEW METHODS: The data sources were searched and selected studies were assessed using quality criteria. In total, 28 prospective diagnostic studies were identified reporting several suspected conditions plus one of patient satisfaction. Analyses were then performed to establish sensitivities, specificities, likelihood ratios and confidence intervals. The relative cost-effectiveness of adopting MRCP scanning in the investigation of the biliary tree was undertaken using a probabilistic economic model. RESULTS: The median sensitivity for choledocholithiasis (13 studies) was 93% and the median specificity 94%. The median likelihood ratio for a positive value was 15.75 and for a negative value 0.08. Reported sensitivities for malignancy were somewhat lower, ranging from 81 to 86%, and specificities ranged from 92 to 100%. There was some evidence that MRCP is an accurate diagnostic test in comparison to ERCP, although the quality of studies was moderate. Claustrophobia prevented at least some patients from having MRCP in ten of the 28 studies. The other 18 studies did not mention claustrophobia. The probability of avoiding unnecessary diagnostic ERCP is estimated at 30%. These patients could avoid the unnecessary risk of complications and death associated with diagnostic ERCP, and substantial cost saving would be gained. The overall expected cost saving associated with MRCP is GBP149; the overall expected gain in quality-adjusted life-year is estimated at 0.011. CONCLUSIONS: There is some evidence that MRCP is an accurate investigation compared with diagnostic ERCP, although the values for malignancy compared with choledocholithiasis were somewhat lower. The quality of studies was moderate. The limited evidence on patient satisfaction showed that patients preferred MRCP to diagnostic ERCP. The estimated clinical and economic impacts of diagnostic MRCP versus diagnostic ERCP are very favourable. The baseline estimate is that MRCP may both reduce cost and result in improved quality of life outcomes compared with diagnostic ERCP. Further research is suggested to compare MRCP and diagnostic ERCP with final diagnosis and also with the full range of target conditions; to examine patient satisfaction and ways of reducing problems with claustrophobia; to look at protocols to help identify who could most benefit from MRCP or ERCP; to assess the relative need and urgency of patient access to magnetic resonance imaging services, and also to determine how demand would affect availability and potential cost savings.

The epidemiology of tuberculosis in Victoria.

AIMS: To describe the epidemiology of Mycobacterium tuberculosis (MTb) in Victoria, Australia. METHODS: We analysed data from the Victorian Mycobacterium Reference Laboratory database and MTb notifications to Health and Community Services Victoria, for the period 1948 to 1992. RESULTS: The annual number of notified tuberculosis cases peaked at 1143 in 1954 and declined to 266 in 1992. The incidence rate decreased from 47 to 6.2 per 100,000 in the same period. The pattern of tuberculosis has changed significantly over the last two decades, reflecting the high prevalence of MTb in recent immigrants, particularly in those from South-East Asia. Among people born overseas the number of cases increased from 40% of notifications in 1970 to 80% in 1990; they are younger, more likely to be female and to have extrapulmonary disease, than their Australian-born counterparts. Between 1987 and 1991, the mean annual incidence of tuberculosis in people born in Australia and South-East Asia respectively was 1.5 and 47.5 per 100,000. People born in Vietnam, Cambodia and the Philippines had rates between 100 and 400 per 100,000. These rates have remained stable during the last six years. Almost 50% of migrant patients presented within five years, and 30% within two years, of arrival in Australia. The estimated mean annual incidence of MTb in homeless men between 1984 and June 1992 was 80 per 100,000. Resistance to all first-line drugs increased from 10.8% of all isolates in 1981 to 14.7% in 1990. The incidence of multi-drug resistant MTb (MDR-MTb) has been consistently less than 2% of isolates per year in the past 15 years. There were 14 cases of MTb and HIV between 1985 and June 1992. The mean annual incidence of MTb in people with AIDS is 1579 per 100,000 (range, 570-2420 per 100,000), with a relative risk of 236 (95% confidence interval [CI], 134-414). MDR-MTb has not been documented in HIV-infected individuals in Victoria. CONCLUSION: Tuberculosis remains an important public health concern. Groups at high risk include people born overseas, the homeless, and people infected with HIV. Physicians caring for AIDS patients should consider the diagnosis of MTb, since its incidence in AIDS patients is so high. Our data suggest possible shortcomings in current methods of screening and prophylactic treatment of migrants and refugees. The rising rate of drug resistance cannot be ignored. We should consider strategies to ensure judicious use of anti-tuberculous drugs by physicians, and optimal patient compliance. These issues are critical to the future of tuberculosis control in Victoria.

Postmenopausal estrogen replacement and risk for venous thromboembolism: a systematic review and meta-analysis for the U.S. Preventive Services Task Force.

BACKGROUND: Postmenopausal estrogen replacement is widely used in the United States but poses important health risks. PURPOSE: To assess the risk for venous thromboembolism with postmenopausal estrogen replacement by using literature review and meta-analysis. DATA SOURCES: All relevant English-language studies identified in searches of the MEDLINE (1966 to December 2000), HealthSTAR (1975 to December 2000), and Cochrane Library databases, and references lists of key articles. STUDY SELECTION: All published studies of postmenopausal estrogen replacement reporting venous thromboembolism as an outcome or adverse event. DATA EXTRACTION: 12 studies of estrogen were identified (3 randomized, controlled trials; 8 case-control studies; and 1 cohort study). Data were extracted on participants, interventions, event rates, and confounders. Two reviewers independently rated study quality on the basis of established criteria. DATA SYNTHESIS: A Bayesian meta-analysis was conducted. When data from all studies were pooled, current estrogen use was associated with an increased risk for venous thromboembolism (relative risk, 2.14 [95% credible interval, 1.64 to 2.81]). Estimates did not significantly change when studies were pooled according to study design, quality score, or whether participants had preexisting coronary artery disease. The absolute rate increase was 1.5 venous thromboembolic events per 10 000 women in 1 year. Six case-control studies that reported risk according to duration of use found that risk was highest in the first year of use (relative risk, 3.49 [credible interval, 2.33 to 5.59]). CONCLUSION: Postmenopausal estrogen replacement is associated with an increased risk for venous thromboembolism, and this risk may be highest in the first year of use.

Hoarding: a review.

BACKGROUND: Hoarding is currently categorized as a symptom of both obsessive-compulsive disorder (OCD) and obsessive-compulsive personality disorder. However, hoarding has also been documented in association with other psychiatric disorders, raising questions about the classification, psychobiology and treatment of these symptoms. This paper reviews the literature on hoarding. METHOD: A computerized literature search was done using the MEDLINE database. Relevant references were collated and were used to obtain additional literature on hoarding behavior. RESULTS: Although hoarding may meet DSM-IV diagnostic criteria for a compulsion, this symptom is also seen in a range of other disorders. Nevertheless, the phenomenology of hoarding remains under-researched. In addition, the psychobiology and treatment of hoarding remains relatively poorly understood, although in certain aspects there may be some overlap with the symptoms of OCD. CONCLUSIONS: Further research on the phenomenology, psychobiology and treatment of hoarding is clearly needed. A neuro-ethological view of hoarding as a spectrum symptom seen not only in OCD, but also in other disorders, may provide a useful heuristic for current clinical practice and for future empirical research.

[Are children and adolescents less physically active today than in the past?].

In recent years it has been claimed that Norwegian children and youth have reduced their level of physical activity and fitness. The aim of this systematic review was to investigate whether the amount of physical activity or level of physical fitness have changed among Norwegian children and youth during the past decades. We searched for relevant information in databases and reference lists and established contacts with scientists working in this field. The quality of the studies was evaluated on the basis of selection bias, information bias and adequate reporting of results. Five repeated cross-sectional studies of healthy boys and girls in the period from 1950 to 1997 were included. Three are based on tests of physical fitness and two of self-reported physical activity. The studies indicate that the physical fitness of the older boys has been reduced, the level of activity has been lowered, the percentage of inactive youth has increased and there are now larger variations in physical fitness. We conclude that there seems to be a negative trend in the level of physical fitness and physical activity of children and youth. This shows the need for interventions. The need for standardised parameters for physical activity is apparent.

Review of objective topographic facial nerve evaluation methods.

OBJECTIVE: This study is a critical review of the described methods for objective topographic evaluation of facial nerve function to identify areas of consensus and point to future research topics. SOURCES AND STUDY SELECTION: Original research articles on the subject were identified through the Medline database and reference cross-checking. DATA EXTRACTION AND SYNTHESIS: The articles were grouped according to the methodology used for topographic facial nerve evaluation. The advantages and shortcomings of each method are evaluated. The results obtained in each publication are presented in light of the method used. CONCLUSION: Measurements localized around the facial area under investigation show maximal displacement, whereas other sites exhibit much smaller displacements. Large displacements in these locations can be used to assess synkinesis and contractures. Large intersubject variability of the same measure is found. Both linear measurement and image-subtracting techniques hold promise. but until comparative studies are performed, the best method will remain controversial. Simple systems, accurately evaluating facial motor function, are yet to be developed.

Cervical ripening and labor induction with a controlled-release dinoprostone vaginal insert: a meta-analysis.

OBJECTIVE: To systematically review published randomized trials that compared efficacy of a 10-mg, controlled-release dinoprostone vaginal insert with other prostaglandins for cervical ripening and labor induction. DATA SOURCES: We supplemented a search of entries in electronic databases with references cited in original studies and review articles to identify randomized clinical trials of dinoprostone vaginal inserts for cervical ripening and labor induction. METHODS OF STUDY SELECTION: We evaluated, abstracted data, and assessed the quality of randomized clinical trials on the efficacy of dinoprostone vaginal inserts as cervical ripening and labor induction agents. Only published randomized trials were included in this meta-analysis. TABULATION, INTEGRATION, AND RESULTS: Seventeen studies were identified, eight of which met our criteria for metaanalysis. Those eight trials included 964 subjects, 490 of whom were allocated to dinoprostone vaginal inserts and 474 to other prostaglandin (PG) preparations. We calculated an estimate of the odds ratio (OR) and risk difference for dichotomous outcomes, using a random- and fixed-effects model. Continuous outcomes were pooled using a variance-weighted average of within-study difference in means. Compared with women who received other PG preparations, those who received dinoprostone vaginal inserts had lower incidence of vaginal delivery within 12 hours of PG application (OR 0.55, 95% confidence interval 0.39, 0.79). Vaginal inserts were associated with longer intervals to vaginal delivery and lower rates of active labor. There were no differences in cesarean delivery rates, incidence of hyperstimulation, or need for oxytocin augmentation between dinoprostone and other PGs. CONCLUSION: Dinoprostone vaginal insert was less effective than other prostaglandins for cervical ripening and labor induction.

Medical oxygen and air travel.

This report responds to a resolution that asked the American Medical Association (AMA) to take action to improve airport and airline accommodations for passengers requiring medical oxygen. Information for the report was derived from a search of the MEDLINE database and references listed in pertinent articles, as well as through communications with experts in aerospace and emergency medicine. Based on this information, the AMA Council on Scientific Affairs determined that commercial air travel exposes passengers to altitude-related hypoxia and gas expansion, which may cause some passengers to experience significant symptoms and medical complications during flight. Medical guidelines are available to help physicians evaluate and counsel potential passengers who are at increased risk of inflight hypoxemia. Supplemental oxygen may be needed for some passengers to maintain adequate tissue oxygenation and prevent hypoxemic complications. For safety and security reasons, federal regulations prohibit travelers from using their own portable oxygen system onboard commercial aircraft. Many U.S. airlines supply medical oxygen for use during flight but policies and procedures vary. Oxygen-dependent passengers must make additional arrangements for the use of supplemental oxygen in airports. Uniform standards are needed to specify procedures and equipment for the use of medical oxygen in airports and aboard commercial aircraft. Revision of federal regulations should be considered to accommodate oxygen-dependent passengers and permit them to have an uninterrupted source of oxygen from departure to destination.

Inflight medical emergencies.

This report responds to resolutions asking the American Medical Association (AMA) to develop recommendations for the use of medical equipment and technology onboard commercial airlines. Information for the report was derived from a search of the MEDLINE database and references listed in pertinent articles, as well as through communications with experts in aerospace and emergency medicine. Based on this information, the AMA Council on Scientific Affairs determined that, while inflight morbidity and mortality are uncommon, serious events do occur, which require immediate emergency care. Management of serious problems requires an integrated emergency response system that ensures rapid notification of medical personnel on the ground, assistance from appropriately trained flight crews and passenger volunteers (if available), and adequate medical supplies and equipment to stabilize the victim. Physicians have an important role in the preflight evaluation and counseling of potential passengers who are at risk of inflight medical complications, and in providing inflight medical assistance. Some U.S. and foreign air carriers are upgrading inflight emergency medical kits and placing automated external defibrillators aboard aircraft. Few data are available regarding the effectiveness of such improvements in improving health or survival outcomes. Recent federal legislation requires assessment of the extent of inflight medical emergencies, including the adequacy of emergency medical supplies and equipment carried onboard commercial airliners. This legislation also should alleviate liability concerns by providing immunity for physicians and others who render inflight medical assistance.

Hand motion assessment and rehabilitation system.

Along with the rapid development of information technology, computers play an increasingly prominent and important role. One current trend is to use computers as instruments for physical rehabilitation. In this study, we introduce a new hand motion assessment and rehabilitation system. This system assesses a user's grip strength and records the sudden changes in air pressure through a circuit and A/D adapter. A PC interface transforms and saves the data in a data record file. The data is then compiled and combined with a patient's case history and keyed into a database as reference for clinical use. The system is highly efficient, cheap and convenient to use. Doctors can use it to monitor and analyze the progress of a rehabilitation program.

Meta-analysis of the effectiveness of parenting programmes in improving maternal psychosocial health.

The purpose of this study was to determine whether group-based parenting programmes are effective in improving maternal psychosocial health. Data sources used were English and non-English language articles published between January 1970 and July 2000, retrieved using a keyword search of a number of biomedical, social science, educational, and general reference electronic databases. Two independent reviewers selected the relevant abstracts and articles. Only controlled trials were included in which participants had been randomly allocated to an experimental and a control group, the latter being a waiting-list, no-treatment or a placebo control group. Studies had to include at least one group-based parenting programme and one standardised instrument measuring maternal psychosocial health. Means, standard deviations, and information regarding study quality were selected from the included studies by two independent reviewers. The treatment effect for each outcome in each study was standardised by dividing the mean difference in post-intervention scores for the intervention and treatment group, by the pooled standard deviation, to produce an effect size. The results were then combined in a meta-analysis using a fixed-effect model. A total of 23 studies met all the inclusion criteria and 17 of these provided sufficient data with which to calculate effect sizes. Fifteen of these studies provided data on the five main outcomes of interest: depression, anxiety/stress, self-esteem, social support, and relationship with partner. The meta-analyses show statistically significant results favouring the intervention group for depression (-0.3, 95% confidence interval [CI] = -0.4 to -0.1), anxiety/stress (-0.5, 95% CI = -0.7 to -0.3), self-esteem (-0.4, 95% CI = -0.6 to -0.1), and relationship with partner (-0.4, 95% CI = -0.7 to -0.2). However, the meta-analysis of the social support data showed no evidence of effectiveness (-0.04, 95% CI = -0.3 to 0.2). Follow-up data were available for only three of the five outcomes. The results show that there were changes favouring the intervention group for self-esteem (-0.4, 95% CI = -0.7 to -0.2), the mother's relationship with her partner (-0.3, 95% CI = -0.8 to 0.1), and depression (-0.2, 95% CI = -0.4 to 0.002), although the confidence intervals for the mother's relationship with her partner and depression both cross zero. It is concluded that parenting programmes can make a significant contribution to the short-term psychosocial health of mothers. While the limited follow-up data are promising, further evidence of their effectiveness in improving maternal mental health is required. It is also suggested that some caution should be exercised before the results are generalised to parents irrespective of the level of pathology present.

Expectant management versus labor induction for suspected fetal macrosomia: a systematic review.

OBJECTIVE: To systematically review and summarize the medical literature regarding the effects of expectant management and labor induction on mode of delivery and perinatal outcomes in patients with suspected fetal macrosomia. DATA SOURCES: We supplemented a search of entries in electronic databases with references cited in original studies and review articles to identify studies assessing management of patients with suspected fetal macrosomia. METHODS OF STUDY SELECTION: We evaluated, abstracted data, and performed quantitative analyses in studies assessing the outcome of patients with suspected fetal macrosomia. Observational studies and randomized trials were included in this systematic review. TABULATION, INTEGRATION, AND RESULTS: Twenty-nine studies were identified, 11 of which met our criteria for systematic review and meta-analysis. These 11 studies included 3751 subjects. Of these, 2700 were managed expectantly, and 1051 underwent labor induction. We calculated an estimate of the odds ratio (OR) with 95% confidence intervals (CIs) for dichotomous outcomes, using random- and fixed-effects models for outcomes. Summary statistics for the nine observational studies showed that, compared with those whose labor was induced, women who experienced spontaneous onset of labor had a lower incidence of cesarean delivery (OR 0.39, 95% CI 0.30, 0.50) and higher rates of spontaneous vaginal delivery (OR 2.07, 95% CI 1.34, 3,19); however, significant differences in these outcomes were not noted when the two randomized trials were assessed. No differences were noted in rates of operative vaginal deliveries, incidence of shoulder dystocia, or abnormal Apgar scores in the analyses of the observational or randomized studies. CONCLUSION: Based on data from observational studies, labor induction for suspected fetal macrosomia results in an increased cesarean delivery rate without improving perinatal outcomes. Although their statistical power is limited, randomized clinical trials have not confirmed these findings.

[Guidelines for pharmacological primary prevention of cardiovascular diseases--who should be treated?].

BACKGROUND: Several clinical practice guidelines for the treatment of hypertension and hypercholesterolaemia are available. The quality of these guidelines varies and the basis for their conclusions is often not clear. We have used systematic and explicit methods in the development of a new set of recommendations. This is the first of three articles describing these guidelines. MATERIAL AND METHODS: Evidence was found by a systematic search in databases and reference lists in guidelines and articles. A set of recommendations was prepared based on a critical appraisal of the literature. These recommendations were revised through discussions with a panel of physicians and agreed upon after several iterations. The guidelines were circulated to professional, governmental and patient organisations, with a request for feedback on errors or shortcomings. RESULTS AND INTERPRETATION: The absolute risk of cardiovascular disease should be used as the basis for discussing with a patient whether drug treatment should be initiated. A 20% risk of developing angina or myocardial infarction over the next ten years is a reasonable threshold for considering treatment. The effects of antihypertensives for persons older than 80 years and of cholesterol-lowering drugs for persons older than 70 years are uncertain. Treatment of blood pressure above 170/100 mm Hg is recommended independent of the risk of cardiovascular disease.

[Which antihypertensive drugs should be used in the primary prevention of cardiovascular disease?].

BACKGROUND: Several clinical practice guidelines for the treatment of hypertension are available. The quality of these guidelines varies and the basis for their conclusions is often not clear. We have used systematic and explicit methods in the development of a new set of recommendations. This is the second of three articles describing these guidelines. MATERIAL AND METHODS: Evidence was found by a systematic search in databases and reference lists in guidelines and articles. A set of recommendations was prepared based on a critical appraisal of the literature. These were revised through discussions with a panel of physicians, and agreed upon after several iterations. The guidelines were circulated to professional, governmental and patient organisations. RESULTS AND INTERPRETATION: Thiazides should be first-choice drugs for the treatment of uncomplicated hypertension. Beta-blockers are a reasonable second choice. The treatment goal should be below 140/90 mm Hg. For combination therapy, thiazides and beta-blockers should be first choice. Diabetic patients should be treated aggressively with a diastolic blood pressure goal below 80 mm Hg. Angiotensin-II antagonists or angiotensin converting enzyme-inhibitors should be first choice drugs for diabetics with microalbuminuria. Patients with hypercholesterolaemia are not given a particular recommendation for choice of drug. Patients with asthma or chronic obstructive pulmonary disease should choose other drugs than beta-blockers. Thiazides should be avoided if the patient has, or has had, gout.

How to identify and assess tasks and challenges of Medical Image Processing.

Research in Medical Image Processing (MIP) is mainly driven by a technology-oriented point of view. However, as an application-oriented field, MIP research should always be able to give an answer to the question of what is the potential benefit of a solved MIP problem or a newly developed MIP-based system supporting a diagnostic or therapeutic process, in terms of outcome criteria like e.g. Quality Adjusted Life Years (QALYs) for the patient or cost savings in health care. As one subtask of establishing a Reference Image Database for MIP R&D Groups, the Working Group on Medical Image Processing of the European Federation for Medical Informatics (EFMI WG MIP) works on an answer. This paper presents the concept and the strategy of how the Most Relevant MIP problems (MRMIP) shall be identified and assessed in the context of improving evaluation of MIP solutions.

The structure of body measurements for the determination of shoe sizing for young Croatian men.

The determination and promotion of the system of shoe sizing requires accurate knowledge of morphological properties of the foot and lower leg of the tested population. Similarly it is necessary to establish the occurrence and regional distribution of definite sizes in the tested population. Possible regional differences in morphological properties must not be ignored because it has been established by means of anthropological measuring that both foot dimensions and foot shapes differ between populations and within the same population. This has been proven by the investigation of body measures, carried out for the purpose of establishing a system of footwear sizes, which was executed on a randomly selected sample of 4,268 healthy and normally developed males aged 18-22. The investigation was carried out in 1993 on five locations each of which representing a definite region of the Republic of Croatia: Jastrebarsko (central), Koprivnica (northwestern), Pula (southwestern), Sinj (southern) and Pozega (northeastern). The measuring instrument was 31 foot and lower-leg sizes according to the existing ISO standards for footwear. Interregional differences are significant in all body measures. The role and the contribution of individual measures to these differences has been established by means of discriminatory analysis with regions as a priori defined samples. In order to constitute a convenient and purposeful standard for the footwear size system it is necessary to work out a database with referent values for the same system.
