[Resident old-age psychiatrists need training in the interpretation of cerebral imaging: a pituitary incidentaloma]. / Interpretatie van cerebraal beeldvormend onderzoek in de opleiding tot ouderenpsychiater: een hypofyse-incidentaloom.

Due to the increased use of cerebral imaging with higher sensitivity, the old-age psychiatrist is more likely to find unexpected lesions. We report on a 73-year-old man with schizoaffective disorder and increasing cognitive deterioration. When given a diagnostic MRI cerebrum a pituitary incidentaloma was found. An overview of the literature shows a high prevalence of pituitary incidentalomas. Complications are generally rare, but one should be alert. The old-age psychiatrist should take the lead in the assessment and interpretation of such imaging results. The relevant skills for this task should be developed in the field of old-age psychiatry during the residency training in psychiatry.

[Can I have some sunshine to cheer me up? vitamin D deficiency and depression in the elderly]. / 'Waar is de zon die mij zal verblijden .'; vitamine D-deficiëntie en depressie bij ouderen.

Vitamin D deficiency is very common in the elderly, and the geriatric patient is probably at even greater risk. Vitamin D plays an important role in calcium homeostasis; recent studies point to a possible causal link between vitamin D deficiency and the development and severity of depression. In this article we focus on an 80-year-old patient with depression and severe vitamin D deficiency and give advice on the diagnosis and treatment of vitamin D deficiency. To supplement the current multidisciplinary guidelines on depression, we recommend routine testing of serum vitamin D level prior to confirming the diagnosis of depression in the elderly.
