[The emotions of oncologists]. / Az onkológusok érzelmei.

Emotions are parts of organizational reality to an ever increasing extent. Importantly, they are not just tools in the hand of healthcare workers to achieve better physician / healthcare professional-to-patient interactions but intrinsic processes and characteristics with psychic, cognitive and somatic actions. For a thorough investigation of the issue, a PANAS-X questionnaire was used to examine the emotions of 187 physicians and other healthcare professionals, all engaged in oncology, in 2009. The research succeeded in exploring the overall emotional state oncology professionals had assumed in relation with their job as well as enabled the authors of this study to draw the respondents' emotional map and assess their fundamental emotional attitudes. Furthermore, the authors managed to identify groups of respondents that had felt more intense positive, and/or less intense negative emotions that are socially accepted than others. They included those of senior experienced oncologists, males, individuals with families, childless individuals, ward workers, and skilled professionals. According to the findings, the range of emotions an oncologist experiences / feels intently during his everyday work is dependent upon a great number of factors.

Computed tomography and transcranial Doppler findings in acute and subacute phases of intracerebral hemorrhagic stroke.

BACKGROUND AND PURPOSE: The hematoma volume is an important determinant of outcome and a predictor of clinical deterioration in patients with intracerebral hemorrhage (ICH). Our goal was to evaluate alterations in the cerebral circulation, in respect to hemorrhage and edema volume changes, using transcranial Doppler (TCD). METHODS: Twenty patients with acute supratentorial ICH were examined. Brain, hematoma, and edema volumes were calculated from CT scans performed at admission and 2 weeks later. Data were compared with those obtained from bilateral TCD recordings of the middle cerebral arteries. RESULTS: During TCD examination, blood flow velocities did not change, cerebral perfusion pressure (CPP) and resistance area product (RAP) decreased (P = .006, P = .002) while cerebral blood flow index (CBFI) remained constant on the affected side. Although hemorrhage volume did not correlate with RAP in the acute phase, correlation was found in the subacute phase (r = -.44, P = .04). CONCLUSIONS: TCD monitoring sensitively demonstrates the hemodynamic change caused by ICH but the severity of the changes does not correlate with the volume of the ICH in acute stage. The CPP, RAP, and CBFI values are more sensitive parameters than the absolute velocity values, therefore they contribute more to the understanding of hemodynamic changes developed after spontaneous ICH.

Smartphones, tablets and mobile applications for radiology.

BACKGROUND: Smartphones are phone devices that may also be used for browsing, navigation and running smaller computer programs called applications. One may consider them as compact personal computers which are primarily to be used for making phone calls. Tablets or "tablet PCs" are fully functioning standalone computers the size of a thin LCD monitor that use the screen itself for control and data input. Both of these devices may be categorized based on the mobile operating system that they use. The aim of this study is to illustrate how smartphones and tablets can be used by diagnostic imaging professionals, radiographers and residents, and to introduce relevant applications that are available for their field. MATERIALS AND METHODS: A search was performed on iTunes, Android Market, Blackberry App World, and Windows Phone Marketplace for mobile applications pertinent to the field of diagnostic imaging. The following terms were applied for the search strategy: (1) radiology, (2) X-ray, (3) ultrasound, (4) MRI, (5) CT, (6) radiographer, (7) nuclear medicine. Two radiologists and one radiology resident reviewed the results. Our review was limited to english-language software. Additional applications were identified by reviewing the list of similar software provided in the description of each application. We downloaded and installed all applications that appeared relevant to an appropriate mobile phone or tablet device. RESULTS: We identified and reviewed a total of 102 applications. We ruled out 1 non-English application and 20 other applications that were created for entertainment purposes. Thus our final list includes 81 applications in the following five categories: diagnostic reading, decision support applications, medical books, interactive encyclopedias, and journal reading programs. CONCLUSION: Smartphones and tablets offer new opportunities for diagnostic imaging practitioners; these easy-to-use devices equipped with excellent display may be used for diagnostic reading, reference, learning, consultation, and for communication with patients.
