[Strokes and Giant cell arteritis: imaging characteristics].

Giant cell arteritis (GCA) is associated with an increased risk of cardio- or cerebro-vascular death. The stroke rate in patients with GCA varies between 2.7 and 7.

[Oral administration of medicines in elderly patients and adaptation of galenic forms].

Physiological ageing and pathologies can have an influence on the pharmacology of numerous medicines, leading to serious iatrogenic accidents, polypharmacy and incorrect use of a medicine in elderly people. An observational study carried out in a short-stay geriatric unit focused on the issues surrounding the difficulties the elderly may encounter when taking medicines and the prevalence of the manipulation of galenic forms.

[Iron deficiency in elderly patients: use of biomarkers].

Iron deficiency, due to blood loss or malabsorption, is commonly observed in geriatric practice. In elderly people, association of inflammatory diseases to iron loss makes diagnosis of absolute iron deficiency sometimes difficult. In case of inflammation, the interpretation of usual biomarkers of iron deficiency (serum ferritin, transferrin saturation, serum iron) may be difficult.

[Analysis of 736 blood transfusions in a geriatric teaching hospital].

Background: Red blood cell transfusion in elderly patients with anemia requires taking into account a hemoglobin threshold, as well as comorbidities that may be decompensated by anemia. In the absence of consensual indications for blood transfusion in the elderly population, it seems important to evaluate the practical approach of blood transfusion in geriatrics. We analyzed prescriptions of red blood cell transfusion in very old patients hospitalized in a geriatric teaching hospital.

[Sleep apnea syndrome and cognitive impairment].

The sleep apnoea syndrome is a common disorder, unrecognised in the elderly. Several studies have shown that it can cause or exacerbate cognitive impairment, mainly related to attention, memory and learning and adaptation abilities. However, continuous positive airway pressure treatment appears to be effective on these cognitive disorders, including in elderly patients.

[Hodgkin lymphoma in the elderly].

We report a case of Hodgkin's lymphoma in a patient aged 75, presenting with acute cardiopulmonary insufficiency, hospitalized in a geriatrics ward. The deterioration of his general condition and the discovery of several lymph nodes led us to perform an aspiration of a lymph node and a bone marrow biopsy. Reed-Sternberg cells, pathognomonic of Hodgkin's disease were identified on the smears and biopsy sections.
