Recording clinical data--from a general set of record items to case report forms (CRF) for clinics.

Standardising a documentary language makes only sense if we use it for documentation consequently. Using an example of Paediatric Oncology in Germany we have developed a procedure that generates CRFs from a documentary language. The introduced procedure has proved to be feasible in practice. With it we can support developers of documentation systems in creating their CRFs; through the guaranteed use of the documentation terminology we further achieve that information recorded with the created CRFs may be statistically analysed across different institutions.

[Effective case records of Luo Tianyi in the army as recorded in Wei Sheng Bao Jian (hygienic precious minor)].

During his life in the army in 1252 - 1261, Luo Tianyi wrote down case records taken from his patients, including soldiers, military officials and their relatives. In addition to infectious diseases such as malaria, dysentery, vomiting and diarrhea and seasonal epidemics, he also treated psychosis, digestive disorders, cold damage, beriberi, coughing and cold in the legs and external diseases such as eye diseases, boils and carbuncles, hernia. The therapeutics he applied included recipes, pills, powders, pastes as well as acu - moxibustion.

Optimisation of a post-processing method to remove the pulse artifact from EEG data recorded during fMRI: an application to P300 recordings during e-fMRI.

In functional cerebral studies, it has been established that co-registered electroencephalography (EEG) measurements and functional magnetic resonance imaging (fMRI) were complementary. However, EEG data recorded inside an MRI scanner are heavily distorted, mainly by the most prominent artifact, the cardiac pulse artifact (PA). We describe an original algorithm which yields a high-quality PA filter and demonstrates how this tool can be used to improve the quality of P300 ERP measurements during event-related fMRI (e-fMRI) experiments. EEG data were acquired in interleaved mode during e-fMRI while six healthy volunteers performed a visual odd-ball task, involving Distractors, Target and Novel stimuli, to elicit P300 components. The PA was corrected with the original algorithm. The temporal variations in the PA were evidenced using a principal component analysis (PCA), on each EEG channel. The procedure yielded several PA templates, which were regressed from the EEG data. The PA removal procedure was optimised, and then implemented to improve the measured P300 components. Regressing the most adequate PA template resulted in a high-quality reduction in spectral power at frequencies associated with the cardiac PA. More reliable P300 component measurements were obtained, evidencing higher amplitudes for Novels (9.76-11.20 microV) than for to Targets (6.3-9.09 microV) in centro-parietal and prefrontal areas. The improvement of the processing of EEG data acquired simultaneously with fMRI data provides a new tool and casts perspectives to study the functional organisation of the brain.

Multiple site silicon-based probes for chronic recordings in freely moving rats: implantation, recording and histological verification.

This paper describes the procedure of assembling a miniature microdrive and silicon probe system for surgical implantation into the adult rat brain. Successful recordings of single and multiunit activity with parallel depth profiles of spontaneous and evoked field potentials are shown. The procedure for histological verification of the position of the silicon probe is described.

Digitized electrocardiograms recorded with bipolar right-infraclavicular leads compared to electrocardiograms recorded with unipolar chest V leads and bipolar lead II.

This article presents a method for the evaluation of cardiac depolarizations in a relatively short time with a minimum number of electrodes. With the negative electrode attached to the right infraclavicular region, voltage variations on the chest surface exhibit larger excursions than do the usual unipolar leads. Peak voltages of the PQRST waveforms measured on 12 normal patients by both methods were similar in polarity but were statistically significantly higher in the right infraclavicular leads. Data are presented on 21 normal patients, which show that digitized signals allow for an expanded time-scale leading to higher resolution of rate of change and onset and offset times. The digitized signals also more clearly define notches that distort the QRS complex. In 55 cardiac patients, the 12-lead unipolar electrocardiograms were visually compared to digitized electrocardiograms recorded by using the bipolar right infraclavicular leads. The authors suggest that RIC leads would be most useful in the design of a pocket-sized digitizing bipolar-lead electrocardiograph.

[Film quality in film mammography. Article II: Signal/noise ratio of the recording system as a quantitative measure of quality. Final evaluation of recording systems (author's transl)].

During consideration of three film mammographic systems (see article I), the concept of signal/noise ratio is developed as a quantitative measure of film quality. The ability to recognise detail related to detail size, film blackening and exposure geometry was studied for various systems, and the quality profiles are discussed. There is a considerable difference in quality between industrial films without screens and film-screen combinations; however, exposure geometry during mammography has a considerable effect which tends to reduce the difference. Consequently, detail sizes of 200 mu to 1,000 mu (including the majority of mammographic micro-calcifications) are shown about equally well. Contrast for the lo-dose system (D = 1.1) is somewhat less than for adequately exposed industrial film (D = 2.0) or for Cronex 75 m with lo-dose screen (D = 1.5 to 2.0). The lo-dose system (D = 1.1) is 8.6 times more sensitive than Cronex 75 m (D = 2.0), and the system Cronex 75 m with lo-dose screens is 11.6 times more sensitive. Over-exposure with the lo-dose system, contrary to industrial film, rapidly leads to unsatisfactory results (loss of contrast and increased granularity for D greater than 1.5). On the other hand it is often not possible to obtain an adequate exposure (D = 2.0) when using industrial film. For these reasons it is often an advantage to examine large breasts (with considerable geometric unsharpness) and the dense breasts of young women with a film-screen combination (eg. lo-dose system) which requires approximately one eighth of the dose necessary for industrial film. For small or easily compressable breasts (little geometric unsharpness) best results are obtained, using an adequate exposure by employing industrial film; radiation dose it then acceptable. Detailed analysis of the systems has shown that the recording system unsharpness of film-screen combinations in mammography should be reduced.

[Neurophysiologic signal recording. New technical and general practice aspects of EEG recording electrodes].

The problem of electrode selection for neurophysiological monitoring, whether for routine clinical applications or special scientific research, still remains to be resolved. In addition to the classical types of electrode-cup (silver/silver chloride or gold) or needle electrodes, new self adhesive electrodes (e.g. zipprep electrodes) for rapid application and reliable recording have recently come onto the market. However, this electrode type can lead to superficial lesions of the skin or inflammatory infiltration, which so far have not been investigated. New developments in the field of cortex electrodes and so-called active electrodes are additionally discussed.
