[Neurosyphilis: a rare cause of dementia]. / La neurosyphilis: une cause rare de démence.

INTRODUCTION: Neurosyphilis had to be evoked in the face of an atypical dementia. CASE RECORD: We describe the case of a 65-year-old man who presented with neurosyphilis suspected to precede behavioral and cognitive problems in the context of risky sexual behavior and was confirmed by serologic tests in the cerebrospinal fluid. DISCUSSION: This case proves the necessity to investigate the possibility of neurosyphilis in subjects with dementia syndrome which does not correspond to classic etiologies.

[Cognitive impairment induced by digoxin intake in patients older than 65 years]. / Troubles cognitifs chez les sujets de plus de 65 ans induits par la prise de digoxine.

Cognitive impairment or clinical signs of dementia in an old patient who receives digoxin, should suggest a digitalis intoxication. Symptoms can be present although a normal digoxin serum concentration. It is recommended to stop the treatment to obtain a regression of dementia symptoms.

[Paroxysmal atrioventricular block due to anticholinesterase therapy]. / Troubles de la conduction auriculoventriculaire paroxystiques liés à la prise d'un anticholinestérasique.

The authors report a case of paroxysmal syncopal complete atrioventricular block due to anticholinesterase therapy occurring after the first administration. The block was reversible. It is therefore important to exclude this cause of atrioventricular block in the elderly in view of the increasing indications of this therapy.

[Trusted person and living will: information and implementation defect]. / Personne de confiance et directives anticipées: défaut d'information et de mise en œuvre.

PURPOSE: The French law allows the persons of age to appoint a trusted person and to draft advance directives in case they are one day in a condition that prevents them from expressing their will regarding their health care. Our study objective was to assess patients' and relatives' knowledge and collecting their opinion regarding these means of expression of their will. METHODS: An anonymous survey by self-administered questionnaire was conducted in the admission offices of the University Hospital of Nancy in April 2011. The questions focused on trusted person and anticipated directives. RESULTS: We collected 367 answers, 61.8% of which were females. Average age of respondents was 48.7 years old (standard deviation: 15.6). Three fourths of respondents were informed of their possibility to appoint a trusted person and were able to establish the difference between a trusted person and a contact person. Respondents mainly chose their spouse (52%). They thought that the trusted person's opinion takes precedence over the family's or relatives' one (64.7%), given that this opinion is based on indications previously provided by the patient (74.8%). The majority of people surveyed were ignorant of the possibility to draft advance directives but were glad of it (57.5%). They would include herein their refusal of unreasonable obstinacy (75.8%), their wishes to withhold/withdraw of some treatments, to stop active treatments in case of high odds of chronic coma or vegetative state (52.8%) or their will to donate organ after death (50.6%). More than three fourths of the patients wished to include these informations on their health care card chip. CONCLUSION: Legal means of expression of the patient's wishes and are not systematically known by the population. The possibility to appoint a trusted person is much more known than that to draft advance directives. After the release in December 2012 of the Sicard report regarding the end of life in France, an important information campaign of the general public remains to be undertaken.
