Acromegaly and aging: a comparative cross-sectional study.

OBJECTIVE: Cognitive and functional geriatric assessment may change in acromegaly. Herein we aimed to determine at which points geriatric assessment of the cases with acromegaly differs from that of general elderly population. DESIGN: In this comparative cross-sectional study, a total of 30 cases with acromegaly (controlled n = 14, uncontrolled n = 16) and 30 gender and body-mass index-matched cases without acromegaly (control group, CG) above 60 years old were included. Cognitive functions were evaluated on the basis of the mini-mental state exam (MMSE). Affective status was determined using the geriatric depression scale. Activities of daily living (ADL) were ranked according to the Barthel index while instrumental activities of daily living (IADL) were graded on the basis of the Lawton scale. Nutritional status was evaluated using the mini-nutritional assessment (MNA). Body composition was measured through bioimpedance analysis. Functional mobility was determined using the Timed Up and Go test (TUG) and muscle strength with the handgrip strength test. RESULTS: Scores on the MMSE were significantly lower in the elderly cases with acromegaly than in the cases without acromegaly (p < 0.001). Dementia was more frequent in the acromegaly group than in the CG (p = 0.04). Total MNA scores were significantly lower in cases with acromegaly than in the CG (p = 0.006). More subjects in the acromegaly group (33%) were at greater risk of malnutrition than in the CG (3%) (p = 0.003). There was greater moderate functional impairment based on Barthel ADL in the acromegaly group than in the CG (p = 0.04). CONCLUSION: Acromegaly may impair cognitive functions, functional mobility and instrumental daily living activities in the geriatric population. With acromegaly, the risk of malnutrition may also increase.

Prevalence and characteristics of restless legs syndrome (RLS) in the elderly and the relation of serum ferritin levels with disease severity: hospital-based study from Istanbul, Turkey.

The RLS is an underdiagnosed condition, characterized by unpleasant sensations in the legs. Pathophysiological mechanisms may include iron deficiency as reflected by low serum ferritin levels and dopaminergic system dysfunction. The purpose of our study was to investigate the prevalence and characteristics of RLS in the elderly and the relation of serum ferritin levels with disease severity. Ambulatory 1012 (621 women, 391 men, mean age: 73.51 ± 7.12 years) consecutive patients above 65 years who admitted to our clinic for any reason were evaluated according to the International RLS Study Group (IRLSSG) criteria: 103 patients (74 women, 29 men, mean age: 72.43 ± 6.31) (10.18%) had RLS diagnosis. Only 9 of them had known RLS. The duration of symptoms was 4.80 ± 4.65 years and 27 patients (26.2%) had positive family history. The average of serum ferritin levels was 39.13 ± 23.74 ng/ml and 71 patients (68.9%) had serum ferritin levels ≤ 50 ng/ml. The disease severity was evaluated with IRLSSG rating scale. Patients were classified as severe-very severe group (n=49) and mild-moderate group (n=54). The ferritin levels of severe-very severe disease group were lower than those of mild-moderate disease group (26.01 ± 15.82 ng/ml versus 49.87 ± 23.24 ng/ml, p<0.001). Our data show that RLS is very common in the elderly and the disease is more severe in patients with lower ferritin levels.

Replicability and reliability of pain assessment forms in geriatrics.

Aim of the study was to investigate the replicability and reliability of the multi-dimensional health assessment questionnaire (MDHAQ) and visual analog scale (VAS) in young and elderly individuals with chronic pain. Ambulatory patients, 20 of them aged above 65 years and complaining about chronic pain and 20 patients with the age of 40 and younger working in a factory were assessed with VAS and MDHAQ. The assessment was repeated to investigate the replicability and reliability of both tests. According to MDHAQ disability index (DI), the elderly had more complains on the first and second day of the study (p<0.001). In terms of changes between first and second days, DI scores of the elderly group (r=0.634; p=0.003) and the younger group (r=0.888; p<0.001) had quite similar responses. Criteria for the assessment of pain, fatigue and general condition according to MDHAQ were similar in both groups in terms of changes between first and second day of the study, there was no significant differences between the groups. But while responses in the younger group according to these 3 parameters were highly reliable, the elderly group's responses were reliable only for their last week pain assessment. Both tests were replicable in the elderly group, VAS and MDHAQ were especially applicable for the last time phase of their pain; while fatigue, general health condition and DI indicated diminished reliability in the elderly group, compared to the young group.
