[Appropriate medication prescribing in older people]. / Bon usage des médicaments chez le sujet âgé.

Drug-induced adverse effects are one of the main avoidable causes of hospitalization in older people. Numerous lists of potentially inappropriate medications for older people have been published, as national and international guidelines for appropriate prescribing in numerous diseases and for different age categories. The present review describes the general rules for an appropriate prescribing in older people and summarizes, for the main conditions encountered in older people, medications that are too often under-prescribed, the precautions of use of the main drugs that induce adverse effects, and drugs for which the benefit to risk ratio is unfavourable in older people. All these data are assembled in educational tables designed to be printed in a practical pocket format and used in daily practice by prescribers, whether physicians, surgeons or pharmacists.

[Radiation pneumonitis: a rare and potentially severe pneumonia. Usefulness of corticosteroids]. / Pneumopathie post-radique aiguë: une pneumopathie rare, potentiellement grave et très corticosensible.

We report a 80-year-old woman who presented with asthenia, confusion and abdominal pain, leading to a diagnosis of severe pneumonia complicated by a colonic pseudo-obstruction. The unfavourable outcome with antibiotic treatment and a recent past medical history of thoracic radiotherapy pointed to a possible diagnosis of radiation pneumonitis. Absence of other explanation and the rapid improvement with corticosteroids confirmed this rare and potentially serious diagnosis, especially among elderly people.

[Usefulness of brain natriuretic peptide and N-terminal pro-brain natriuretic peptide in the elderly]. / Intérêt du peptide natriurétique B et du N-terminal-proBNP chez le sujet âgé

B-type natriuretic peptide and N-terminal pro-brain natriuretic peptide are biomarkers secreted both in response to myocardial stretch and increased ventricular wall stress. They are now largely used in cardiovascular disease in adults, especially as diagnostic and prognostic tools. This article aims at synthesizing existing data concerning the usefulness of natriuretic peptides in elderly patients. With aging, co-morbidities such as renal failure are common and lead to an increase in circulating concentrations of natriuretic peptides. Nevertheless, their usefulness is relevant in geriatric practice. Their role has been well established in heart failure, not only in diagnosis, using two thresholds to decrease misclassification, but also in prognosis. In the future, natriuretic peptides could be used as prognosis tools in acute coronary syndrome, in cardiovascular risk assessment or in management of heart valve disease. However, further investigations in elderly people are needed before validating these indications in routine geriatric practice.
