RESUMEN
The epidemiology of sport injuries is well documented. However, the costs are rarely discussed. Previous studies have presented such costs in specific sports or localization. No study has investigated the costs related to injuries in elite floorball. Thus, the aim of this study was to estimate cost of injuries in Swedish elite floorball players. During 1 year, 346 floorball players were prospectively followed. All time-loss injures were recorded. The injured players were asked to complete a questionnaire regarding their costs tied to the injury. Mean costs were calculated by multiplying the total resource use with the collected unit costs and dividing these total costs with the number of injuries as well as players. The results showed that the average cost per injury increased with the level of severity and ranged from 332 to 2358 Euros. The mild and moderate overuse injuries were costlier than the corresponding traumatic injuries. However, the severe traumatic injuries were associated with higher costs than overuse injuries. Knee injuries were the costliest. Our results indicate that there are costs to be saved, if floorball injuries can be avoided. They should be of interest to decision makers deciding whether to invest in preventive interventions.

OBJECTIVE: To assess the diagnostic accuracy of imaging technologies for detecting prostate cancer in patients with elevated PSA-values or suspected findings on clinical examination. METHODS: The databases Medline, EMBASE, Cochrane, CRD HTA/DARE/NHS EED and EconLit were searched until June 2013. Pre-determined inclusion criteria were used to select full text articles. Risk of bias in individual studies was rated according to QUADAS or AMSTAR. Abstracts and full text articles were assessed independently by two reviewers. The performance of diagnostic imaging was compared with systematic biopsies (reference standard) and sensitivity and specificity were calculated. RESULTS: The literature search yielded 5141 abstracts, which were reviewed by two independent reviewers. Of these 4852 were excluded since they did not meet the inclusion criteria. 288 articles were reviewed in full text for quality assessment. Six studies, three using MRI and three using transrectal ultrasound were included. All were rated as high risk of bias. Relevant studies on PET/CT were not identified. CONCLUSION: Despite clinical use, there is insufficient evidence regarding the accuracy of imaging technologies for detecting cancer in patients with suspected prostate cancer using TRUS guided systematic biopsies as reference standard.

AIMS/HYPOTHESIS: The aim of the present study was to estimate the prevalence and healthcare costs of diabetic retinopathy (DR). METHODS: This population-based study included all residents (n = 251,386) in the catchment area of the eye clinic of Linköping University Hospital, Sweden. Among patients with diabetes (n = 12,026), those with and without DR were identified through register data from both the Care Data Warehouse in Ostergötland, an administrative healthcare register, and the Swedish National Diabetes Register. Healthcare cost data were elicited by record linkage of these two registers to data for the year 2008 in the Cost Per Patient Database developed by Ostergötland County Council. RESULTS: The prevalence of any DR was 41.8% (95% CI 38.9-44.6) for patients with type 1 diabetes and 27.9% (27.1-28.7) for patients with type 2 diabetes. Sight-threatening DR was present in 12.1% (10.2-14.0) and 5.0% (4.6-5.4) of the type 1 and type 2 diabetes populations respectively. The annual average healthcare cost of any DR was euro72 (euro53-91). Stratified into background retinopathy, proliferative DR, maculopathy, and the last two conditions combined, the costs were euro26 (euro10-42), euro257 (euro155-359), euro216 (euro113-318) and euro433 (euro232-635) respectively. The annual cost for DR was euro106,000 per 100,000 inhabitants. CONCLUSIONS: This study presents new information on the prevalence and costs of DR. Approximately one-third of patients with diabetes have some form of DR. Average healthcare costs increase considerably with the severity of DR, which suggests that preventing progression of DR may lower healthcare costs.

OBJECTIVE: To assess the cost-effectiveness of the use of cardiotocography (CTG) complemented with fetal electrocardiography and ST analysis compared with the use of CTG alone in term deliveries when a decision has been made to use fetal monitoring with a scalp electrode. DESIGN: A cost-effectiveness analysis based on a probabilistic decision model incorporating relevant strategies and lifelong outcomes. SETTING: Maternity wards in Sweden. POPULATION: Women with term fetuses after a clinical decision had been made to apply a fetal scalp electrode for internal CTG. METHODS: A decision model was used to compare the costs and effects of two different treatment strategies. Baseline estimates were derived from the literature. Discounted costs and quality-adjusted life years (QALYs) were simulated over a lifetime horizon using a probabilistic model. MAIN OUTCOME MEASURES: QALYs, incremental costs, and cost per QALY gained expressed as incremental cost-effectiveness ratio (ICER). RESULTS: The analysis found an incremental effect of 0.005 QALYs for ST analysis compared with CTG; the ST analysis strategy was also moreover associated with a euro56 decrease in costs, thus dominating the CTG strategy. The probability that ST analysis is cost-effective in comparison with CTG is high, irrespective of the willingness-to-pay value for a QALY. CONCLUSIONS: Compared with CTG alone, ST analysis is cost-effective when used in term high-risk deliveries in which there is a need for internal fetal monitoring.

A comparison has been made of [(123)I]meta-iodobenzylguanidine ([(123)I]MIBG) and [(111)In]pentetreotide scintigraphy in 54 patients with a variety of neuroendocrine tumors of whom 46 patients had metastatic disease. [(111)In]Pentetreotide scintigraphy was more sensitive in detecting metastatic lesions, as demonstrated on computed tomography and/or magnetic resonance scanning, than [(123)I]MIBG: 67% vs. 50% for carcinoid tumors (n = 24), 91% vs. 9% for pancreatic islet cell tumors (n = 12), 100% vs. 60% for medullary thyroid carcinomas (n = 5), and 75% vs. 100% for pheochromocytomas/paragangliomas (n = 4). In only 2 patients were lesions seen with [(123)I]MIBG scanning that were not apparent with [(111)In]pentetreotide. With the exception of pancreatic islet cell tumors, both radionuclides exhibited a similar sensitivity in detecting hepatic metastases, whereas in three patients the two radionuclides exerted a complementary role as different deposits exhibited uptake to only 1 or the other radionuclide. Hepatic metastases were the most important clinical predictor of a positive scan for both radionuclides. Neither elevated 5-hydroxyindoleacetic acid levels nor any other hormonal marker was predictive of a positive scan. In 8 patients with clinical and/or hormonal evidence of a neuroendocrine tumor but negative conventional radiology, [(111)In]pentetreotide scintigraphy was more sensitive than [(123)I]MIBG (37.5% vs. 12.5%) in detecting lesions. In conclusion, scintigraphy with [(111)In]pentetreotide detects more metastatic lesions than [(123)I]MIBG in patients with carcinoid and pancreatic islet cell tumors and medullary thyroid carcinomas; [(123)I]MIBG scintigraphy may be more sensitive for sympathoadrenomedullary tumors. The radionuclides may exert a complementary role in the detection and treatment of neuroendocrine tumors in occasional patients, as areas of different pattern of uptake were identified within the same patient. These data have implications not only for staging such tumors, but also for identifying patients who might benefit from treatment using either [(131)I]MIBG or radioactive somatostatin analogs.

The first sites with Pliocene and Pleistocene mammals west of the Rift Valley in Central Africa in northern Chad were reported in 1959 (ref. 1), and documented the presence of mixed savannah and woodland habitats. Further sites and a probable Homo erectus cranio-facial fragment were subsequently discovered. In 1993 a survey of Pliocene and Pleistocene formations in the Borkou-Ennedi-Tibesti Province of Chad (B.E.T.) led to the discovery of 17 new sites in the region of Bahr el Ghazal (classical Arabic for River of the Gazelles) near Koro Toro. One site, KT 12 (15 degrees 58'10"N, 18 degrees 52'46"E) yielded an australopithecine mandible associated with a fauna biochronologically estimated to be 3.0-3.5 Myr old. Australopithecine species described since 1925 are known from southern Africa and from sites spread along the eastern Rift Valley from Tanzania to Ethiopia (Fig. 1). This new find from Chad, which is most similar in morphology to Australopithecus afarensis, documents the presence of an early hominid a considerable distance, 2,500 km, west of the Rift Valley.
