problems in different age, sex and seasons were determined from the
relative concentration of thyroid hormones (T3 and T4)
and thyroid stimulating hormone (TSH) in 9054 patients. These patients
visited the radioimmunoassay (RIA) laboratory of the Institute of Radiotherapy
and Nuclear Medicine (IRNUM) Peshawar during the years 1984-1990 (except
1987) and 1995 and 1996. The patients were classified into infants,
children, adults and old age groups according to their age, into males
and females according to their sex and into winter, spring, summer and
autumn according to their visit to the laboratory. T3 and
T4 in the blood serum of these patients were determined by
radioimmunoassay (RIA) and their TSH in the blood serum were determined
by immuno-radiometric assay (IRMA). The data revealed that 54% thyroid
patients were having normal levels of T3, T4 and
TSH. Considering all age groups together, the frequencies of hyperthyroidism/Thyrotoxicosis
and hypothyroidism were 5.1 and 4.0% respectively. Similarly, the frequencies
of subclinical hyperthyroidism and subclinical hypothyroidism were 5.8
and 5.4% respectively. The frequencies of other thyroid problems were
25.8%. The frequency of hyperthyroidism/ thyrotoxicosis was higher in
adults group (2.9%) followed by old age group (2.0%), children group
(0.2%) and infants group (0.01%). Similarly the frequency of hypothyroidism
was higher in adults group followed by old age group, children group
and infants group were 1.8, 1.3, 0.7, 0.1% respectively. Similar pattern
of frequencies of subclinical hyperthyroidism, subclinical hypothyroidism
and other thyroid problems was observed. Iodized salted should be used
only in iodine deficient areas and with caution.]]>Connolly, R.J.,1971212681271Connolly, R.J.,19732171174Gadde, K.M. and R.R. Krishnan,199424521524Galofre, J.C., L. Fernandez-Calvet, M.
