Senile diabetes and bone mineral density.

Bone mineral density was determined in a series of 67 elderly diabetics (38 males and 29 females) and 40 non-diabetic elderly subjects (20 males and 20 females) at the third medial and tenth ultradistal of the non-dominating radius using an X-ray densitometer (DEXA). Bone metabolism markers (Ct, PTH, HOP, UCA, AP, Vit-25-OH-D, BGP) were also measured. Our results indicate that there is no significant difference in values of BMD and the bone metabolism markers studied between diabetic and non-diabetic elderly subjects. We believe that senile diabetes is not a risk factor of onset and maintenance of senile osteoporosis.

Altered laboratory thyroid parameters indicating hyperthyroidism in elderly subjects.

The most common laboratory alterations of thyroid function indicating hyperthyroidism were evaluated in a series of 3015 subjects over 65 years of age by determining total T3, total T4 and TSH. Ultrasound and scintigraphy of the thyroid were performed where necessary. Our results showed a high prevalence of laboratory alterations hyperthyroidism type of around 8.09%, whereas the real prevalence (both clinical and laboratory) is 2.00% with a female/male ratio of 2.00. The most frequent hyperfunctioning thyreopaty is thyroidal adenoma (50%), followed by toxic multinodular goiter (33%) and Basedow's disease (17%). The most common clinical signs of hyperthyroidism involve the neuromuscular system and are often present in the so called 'euthyroid' elderly subject. We conclude that it is very difficult to diagnose hyperthyroidism in the elderly on clinical and laboratory grounds. The most significative laboratory thyroid parameter indicating hyperthyroidism seems to be TSH values below 0.2 IU/ml determined using the ultrasensitive IRMA method.

Altered laboratory thyroid parameters indicating hypothyroidism in elderly subjects.

The altered laboratory thyroid parameters indicating hypothyroidism were evaluated in a series of 3015 subjects over 65 years of age by determining total T3, total T4 and TSH. In addition, clinical signs of hypothyroidism were recorded in a subsample of 300 randomly selected elderly. Our results showed a high prevalence of altered laboratory thyroid parameters indicating hypothyroidism of 17.88%, whereas the real prevalence (both clinical and laboratory) is 1.00% with a female/male ratio of 2.00. The most frequent laboratory alterations was the so-called 'alerted pituitary' status'. The most common clinical signs of hypothyroidism involved the nervous system. We conclude that it is very difficult to diagnose hypothyroidism in the elderly and that the most indicative laboratory alterations seem to be TSH values above 3 IU/ml determined using the IRMA method.
