Impaired Knowledge of Social Norms in Dementia and Psychiatric Disorders: Validation of the Social Norms Questionnaire-Dutch Version (SNQ-NL).

The Social Norms Questionnaire-Dutch version (SNQ-NL) measures the ability to understand and identify social boundaries. We examined the psychometric characteristics of the SNQ-NL and its ability to differentiate between patients with behavioral variant frontotemporal dementia (bvFTD; n = 23), Alzheimer's dementia (AD; n = 26), chronic psychiatric disorders (n = 27), and control participants (n = 92). Between-group differences in the Total score, Break errors, and Overadhere errors were examined and associations with demographic variables and other cognitive functions were explored. Results showed that the SNQ-NL Total Score and Break errors differed between patients with AD and bvFTD, but not between patients with bvFTD and psychiatric disorders. Modest correlations with age, sex, and education were observed. The SNQ-NL Total score and Break errors correlated significantly with emotion recognition and verbal fluency but not with processing speed or mental flexibility. In conclusion, the SNQ-NL has sufficient construct validity and can be used to investigate knowledge of social norms in clinical populations.

Improvement of radiology requisition.

PURPOSE: Inadequate or incomplete information on radiology requisitions may have a substantial impact on the radiological process. This study aimed to evaluate the impact of standardization and computerization of radiology requisitions on the quality of provided data, satisfaction of hospital staff and access time. METHODS: The impact of requisition support was assessed at each step of the improvement process for inpatients: before (Step 1), after standardization (Step 2) and after computerization of radiology requisition (Step 3). The quality of information provided was assessed by proportion of missing data on MRI and CT requisitions. Satisfaction was assessed by an anonymous auto-questionnaire filled by ordering physicians, radiologists and radiology technicians. Access time was prospectively assessed. RESULTS: Standardization of radiology requisition resulted in a significant drop in proportion of missing data. Computerization of radiology requisition, based on the single standardized radiology requisition, further improved the quality of information reported on radiology requisitions. The median access time was significantly improved (from 5 to 3days) for the largest provider of CT requisitions. CONCLUSIONS: Standardization and computerization have a synergistic effect on the overall quality improvement. Moreover, the computerized provider order entry enables traceability of information, makes communication between radiologists and ordering physicians easier and improves examination planning.

Perception of facial expressions in obsessive-compulsive disorder: a dimensional approach.

The study examined the perception of facial expressions of different emotional intensities in obsessive-compulsive disorder (OCD) subtypes. Results showed that the High Risk Assessment and Checking subtype was more sensitive in perceiving the emotions fear and happiness. This suggests that altered affective processing may underlie the clinical manifestation of OCD.

[Consensus statement of an interdisciplinary group of French experts on modalities of diagnosis and medical treatment of Alzheimer's disease at a treatable stage]. / Convergences d'un groupe pluridisciplinaire d'experts français sur les modalités du diagnostic et du traitement médicamenteux de la maladie d'Alzheimer au stade démentiel.

A group of French expert met on the 7th and 8th of February 1998 in order to establish a consensus attitude for Alzheimer's disease diagnosis and treatment. Members were drawn from primary care, geriatrics, neurology and psychiatry. They used the consensus statement of the American Association for Geriatrics, the Alzheimer's Association and the American Geriatrics Society published in JAMA, in October 1997 as a source of data for further consideration. Alzheimer's disease in the most common etiology of dementia. Main clinical features are cognitive impairment and psycho-behavioral disorders. Diagnosis must be one of inclusion and not exclusion. It is based on interviews of informants and family members and office-based clinical assessment. After a physical examination, cognitive function must be evaluated using the Mini-Mental State Examination. A laboratory evaluation should include a complete blood cell count, blood chemistry and determination of thyroid-stimulating hormone. In addition, noncontrast computed tomography head scans are adequate in most cases. Available pharmacologic treatments are not curative but are given to improve quality of life and enhance cognition and behavior. Two cholinesterases inhibitors, tacrine and donepezil, are the only agents officially authorized for treatment of the cognitive impairment in Alzheimer's disease. Mood and behaviour disorder also have to be treated by both pharmacologic and nonpharmacologic strategies. Only pharmacologic treatments will be detailed here. The consensus statements established by this group of experts will be reevaluated each year, considering the new available data on Alzheimer's disease.

[Metastasis of visceral tumors in intracranial tumors. Apropos of a metastasis of a lung cancer in an intracranial meningioma]. / Les métastases des cancers viscéraux dans les tumeurs intracrâniennes. A propos d'une métastase d'une cancer pulmonaire dans un méningiome intracrânien.

In a 52 years old man a backward epilepsy revealed a left fronto parietal tumor. The histopathological study shows that it is a meningial tumor composed around by meningocytic proliferation with a metastasis of lung cancer in the middle. This fact was proved only two months after neurosurgical intervention. Thirty three cases of cancer with metastasis in an intracranial primitive tumor have been collected in the literature. The authors study the clinical aspects and etiopathogenic hypothesis of this surprising anatomopathological fact.
