- Abstract
Introduction: Evaluation of immediate total-body CT (iTBCT) scouts during primary trauma care could be clinically relevant for early detection and treatment of specific major injuries. The aim of this study was to determine the diagnostic usefulness of TBCT scouts in detecting life-threatening chest and pelvic injuries. Methods: All patients who underwent an iTBCT during their primary trauma assessment in one trauma center between April 2011 and November 2014 were retrospectively included. Two experienced trauma surgeons and two emergency radiologists evaluated iTBCT scouts with structured questionnaires. Inter-observer agreement and diagnostic properties were calculated for endotracheal tube position and identification of pneumo- and/or hemothorax and pelvic fractures. Diagnostic properties of iTBCT scouts for indication for chest tube placement and pelvic binder application were calculated in comparison to decision based on iTBCT. Results: In total 220 patients with a median age of 37 years (IQR 26–59) were selected with a median Injury Severity Score of 18 (IQR 9–27). There was moderate to substantial inter-observer agreement and low false positive rates for pneumo- and/or hemothorax and for severe pelvic fractures by iTBCT scouts. For 19.8%–22.5% of the endotracheal intubated patients trauma surgeons stated that repositioning of the tube was indicated. Positive predictive value and sensitivity were respectively 100% (95%CI 52%–100%) and 50% (95%CI 22%–78%) for decisions on chest tube placement by trauma surgeon 1 and 67% (95%CI 13%–98%) and 22% (95%CI 4%–60%) for decisions by trauma surgeon 2. Only in one of 14 patients the pelvic binder was applied after iTBCT acquisition. Conclusions: iTBCT scouts can be useful for early detection of pneumo- and/or hemothorax and severe pelvic fractures. Decision for chest tube placement based on iTBCT scouts alone is not recommended.

- Abstract
Background Melioidosis, caused by the Gram-negative bacterium Burkholderia pseudomallei, is an opportunistic infection across the tropics. Here, we provide a systematic overview of imported human cases in a non-endemic country over a 25-year period. Methods All 55 Dutch microbiology laboratories were contacted in order to identify all B. pseudomallei positive cultures from 1990 to 2018. A response rate of 100% was achieved. Additionally, a systematic literature search was performed, medical-charts reviewed, and tissue/autopsy specimens were re-assessed. Results Thirty-three travelers with melioidosis were identified: 70% male with a median-age of 54 years. Risk factors were present in most patients (n = 23, 70%), most notably diabetes (n = 8, 24%) and cystic fibrosis (n = 3, 9%). Countries of acquisition included Thailand, Brazil, Indonesia, Panama, and The Gambia. Disease manifestations included pneumonia, intra-abdominal abscesses, otitis externa, genitourinary, skin-, CNS-, and thyroid gland infections. Twelve (36%) patients developed sepsis and/or septic shock. Repeat episodes of active infection were observed in five (15%) and mortality in four (12%) patients. Post-mortem analysis showed extensive metastatic (micro)abscesses amongst other sites in the adrenal gland and bone marrow. Conclusions The number of imported melioidosis is likely to increase, given rising numbers of (immunocompromised) travelers, and increased vigilance of the condition. This first systematic retrospective surveillance study in a non-endemic melioidosis country shows that imported cases can serve as sentinels to provide information about disease activity in areas visited and inform pre-travel advice and post-travel clinical management.

The added value of information technology (IT) varies widely along firms. The objective of this paper is to analyse the underlying factors that enlarge or reduce the added value of information systems and IT-applications in construction firms. By applying the process-oriented approach of Tallon et al.. (2000) the value of these information systems on the process-level is assessed. Information systems and IT-applications create value for an organization by improving individual business processes, or linkages between processes, or both in terms of Porters’ value chain (Porter and Millar, 1985). Determining the IT-value in a structured and meaningful way requires an operational description of what IT is in those critical value activities. For this analysis, the concept of the IT-based infrastructure of Renkema (2000) is used. By applying the IS Assessment and Contingency Theory of Myers et al.. (1998) critical success factors for the alignment of IT and business processes are shown. In order to verify our expectations, an empirical research was conducted by a multiple case study of five firms in civil engineering and housing and real estate

The extent to which information technology (IT) infrastructures and strategies are aligned with business processes and strategies varies widely along firms. The objective of this paper is to explain the success or failure of IT in construction firms by focusing on the alignment (or lack of it) between business strategy, IT strategy, organizational infrastructure, and IT infrastructure. It is hypothesized that the ‘fit’ among these elements, the domains of the Strategic Alignment Model, is positively related to the Business Value of IT in Construction. The IT Business Value is evaluated in terms of efficiency, effectiveness and business performance. By applying the Strategic Alignment Model to the Dutch construction industry, it is shown that the inadequate alignment between these domains is a major reason for the modest added business value from IT investments in this industry. The first lack of alignment is the technology shortfall: hence IT contributes in an inadequate way to strategic processes of construction firms. The second lack of alignment is the strategy-shortfall: hence the firm strategy impedes the implementation of IT that could generate a high business value.

- Abstract
Background: For the evaluation of severely injured trauma patients a variety of total body computed tomography (CT) scanning protocols exist. Frequently multiple pass protocols are used. A split bolus contrast protocol can reduce the number of passes through the body, and thereby radiation exposure, in this relatively young and vitally threatened population., Purpose: To evaluate three protocols for single pass total body scanning in 64-slice multidetector CT (MDCT) on optimal image quality., Material and Methods: Three total body CT protocols were prospectively evaluated in three series of 10 consecutive trauma patients. In Group A unenhanced brain and cervical spine CT was followed by chest-abdomen-pelvis CT in portovenous phase after repositioning of the arms. Group B underwent brain CT followed without arm repositioning by a one-volume contrast CT from skull base to the pubic symphysis. Group C was identical to Group A, but the torso was scanned with a split bolus technique. Three radiologists independently evaluated protocol quality scores (5-point Likert scale), parenchymal and vascular enhancement and artifacts., Results: Overall image quality was good (4.10) in Group A, more than satisfactory (3.38) in Group B, and nearly excellent (4.75) in Group C (P < 0.001). Interfering artifacts were mostly reported in Group B in the liver and spleen., Conclusion: In single pass total body CT scanning a split bolus technique reached the highest overall image quality compared to conventional total body CT and one-volume contrast CT., (© The Foundation Acta Radiologica 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

- Abstract
Clinically the removal of fibroadenomas is not indicated. However, there are patients who insist upon fibroadenoma removal. An alternative to surgery is the vacuum-assisted biopsy system. Using this system, fibroadenomas up to 4 cm can be successfully removed under ultrasound guidance by taking multiple tissue samples. Using this technique, the cosmetic outcome is better than with surgical excision. The level of patient satisfaction is high.
