[Discrepancies in reported medication use in elderly psychiatric outpatients]

Different fields of study have revealed discrepancies between the reported medication use presented by patients and medical records held by their doctor or apothecary. These also appear to have clinically relevant consequences. At present only two studies have explored medication discrepancies in psychiatry.<br/> AIM: To investigate the occurrence of discrepancies in the reported medication use of a psychiatric elderly out-patient population.<br/> METHOD: Comparing 40 medication records of patients to their respective general practitioner and pharmacy records. Information on their social situation, Mini-Mental State Examination score and diagnosis was collected.<br/> RESULTS: One or more discrepancies were present in 80 percent of cases. Patients living alone had a higher percentage of discrepancies. Patients with cognitive problems or a low score on the Mini-Mental State Examination had less discrepancies.<br/> CONCLUSION: Medication discrepancies are also common in a psychiatric elderly outpatient population.

Loneliness in older adults is associated with diminished cortisol output

OBJECTIVE

Loneliness in older adults has been associated with increased mortality and health problems. One of the assumed underlying mechanisms is dysregulation of the hypothalamic-pituitary-adrenocortical axis (HPA-axis). The purpose of this study was to investigate whether loneliness in older adults is associated with HPA-axis dysregulation and whether this association differs between depressed and non-depressed persons.

METHODS

Cross-sectional data of 426 lonely and non-lonely older adults in the Netherlands Study of Depression in Older Persons (NESDO) were used. Linear regression analyses and multinominal logistic regression analyses were performed to examine the association between loneliness and morning cortisol, cortisol awakening response, diurnal slope and dexamethasone suppression ratio. In all analyses, confounders were introduced. In order to examine whether the association between loneliness and cortisol measures is different in depressed versus non-depressed persons, an interaction term for loneliness x depression diagnosis was tested.

RESULTS

Cortisol output in the first hour after awakening and dexamethasone suppression ratio was lower in lonely participants. There were no significant interactions between loneliness and depression diagnosis in the association with the cortisol measures.

CONCLUSION

This study is the first to investigate the association between the HPA-axis and loneliness in a large group of older adults aged 60-93years. We found lower cortisol output in the first hour after awakening and lower dexamethasone suppression ratio in lonely older depressed and non-depressed adults. Whether diminished cortisol output is the underlying mechanism that leads to health problems in lonely older adults is an interesting object for further study.

[Intestinal pseudo-obstruction during use of baclofen]

In a 75-year-old man acute intestinal pseudo-obstruction was observed during treatment with baclofen 20 mg daily. After discontinuation of the baclofen he recovered completely. No other cause of intestinal obstruction could be demonstrated. Baclofen is an agonist of spinal GABA receptors. It is used in the treatment of spasticity caused by multiple sclerosis or other diseases of the spinal cord, in particular traumatic lesions. Physicians should be aware of this possible adverse effect of baclofen.
