Communication between general practitioners and radiologists: opinions, experience, promises, pitfalls.

PURPOSE: Studies encompassing the views and aspirations of general practitioners (GPs) concerning the radiology report are rare. We present the results of a large-scale survey among GPs in Flanders, Belgium, and examine its implications for the communication between radiologists and GPs. MATERIALS AND METHODS: GPs were invited by e-mail to participate in a survey on the radiology report. Respondents could state their degree of agreement with 46 statements. Besides that, they could freely make suggestions to improve the report. Quantitative results were examined to determine majority convictions. Free text suggestions were searched for motives and convictions. RESULTS: Of 1323 GPs invited, 282 completed forms were prepared for analysis. 96.8% considered the report an indispensable tool. 85.5% were satisfied with it. Itemized reporting of complex examinations was favoured by a very large majority. 83 GPs (29.4%) made suggestions for improvement. Much emphasis was put upon the clinical role of the radiologist. The need to mark key images, to mention meaningful normal findings, to structure the report and to facilitate communication was also frequently mentioned. CONCLUSION: GPs expect the radiologist to think as a clinician and offer clinical answers. An automated electronic information chain may contribute to realize this objective but direct communication should always remain possible.

Developmental changes in semantic verbal fluency: analyses of word productivity as a function of time, clustering, and switching.

We investigated age-related improvement in semantic category verbal fluency (VF) in 309 Dutch schoolchildren attending first to ninth grade. Quantitative analyses of number of correct responses as a function of time as well as qualitative analyses of clustering and switching were conducted. Overall, Dutch VF task performance, i.e., number of correct responses over 60 seconds, was not established before mid-adolescence. This is in line with previously published studies, using VF number of correct responses over 60 seconds as the main outcome measure and examining VF task performance across other cultures and languages (e.g., Italian, French, Hebrew). Next, mean cluster size, a measure of lexico-semantic knowledge, was not established until at least grade 3. In contrast, performance on the VF outcome measures "number of switches/clusters" was established at least 4 years later. Qualitative and quantitative Design Fluency (DF) outcome measures support the notion that the numbers of switches/clusters are valid measures of higher order cognitive functions, such as strategy use and cognitive flexibility. In line of this, VF number of correct responses during 16-60 seconds, a measure of controlled information processing, is established at least 2 years later (i.e., grades 7-8) than number of correct responses during the first 15 seconds time slide, a measure of automatic processing. Finally, environment, i.e., the level of parental education, primarily affected automatic and lexico-semantic knowledge. No effects of sex on VF performance were found. These data suggest that the alternative scoring methods of VF tasks can be used to acquire knowledge on development of lower and higher order cognitive functions in healthy children and the influence of the environment on it.

Hypersomnolence and narcolepsy; a pragmatic diagnostic neurophysiological approach.

Out of a group of 250 consecutive patients who were examined for various disorders of sleep and waking at Ghent University Hospital within a period of 24 months, 30 patients with hypersomnolence associated with a suspected underlying neurological etiology were selected. The population consisted of 15 males and 15 females with mean age of 36 years (range: 16-60 years). Twenty-one patients had had hypersomnolence for more than 2 years. All patients underwent a single night polysomnography (PSG) and a 4-nap multiple sleep latency test (MSLT). PSG was normal in 23 patients. Sleep onset REM period (SOREMP) was defined as the occurrence of REM sleep within 15 min. after initiation of sleep. PSG demonstrated SOREMP's in only 1 patient and showed evidence of obstructive sleep apnea in 4 patients. Two patients had a low sleep efficiency. MSLT demonstrated hypersomnolence in 17 patients of whom 6 showed SOREMP. Significant hypersomnolence was defined as a mean sleep latency < or = 5 min. 4 patients fulfilled the classical clinical and polygraphic criteria (> or = 2 SOREMP) of narcolepsy. In 8 patients the tentative diagnosis of idiopathic CNS hypersomnolence was made. 13 patients did not sleep during MSLT. These results emphasize the relative importance of MSLT. Our limited 4-nap MSLT protocol proved useful in distinguishing narcolepsy from idiopathic CNS hypersomnolence.
