[Selected markers of bone metabolism in boys with constitutional delay of growth and puberty].
The aim of the study was to determine serum concentration and urinary excretion of selected parameters of bone metabolism in boys with constitutional delay of growth and puberty (CDGP) in the relation to pubertal stages. The study group consisted of 41 boys (aged 8 to 18 yrs) with CDGP. Patients were divided on the basis of Tanner's criteria into 4 groups according to the pubertal stage. Serum alkaline phosphatase (AP) activity and serum osteocalcin (OC) concentration as markers of bone growth, as well as urinary deoxypyridinoline (DPD) as a marker of bone resorption were determined. Serum AP activity in 31 (75.6%) boys was within normal age range. Mean values of serum AP activity increased insignificantly from I to IV stage of puberty. Serum OC concentrations were normal in 33 (80.5%) patients. Eight (19.5%) boys showed decreased values of serum OC concentration. Mean OC concentration insignificantly increased with the pubertal stages. DPD urinary excretion was within normal age range in all patients and was the highest in stage III of pubertal stage. No significant abnormalities of bone metabolism parameters in boys with constitutional delay of growth and puberty were found.

Neurodevelopmental dysfunction and specific learning disabilities in school-aged twins.
The frequency of the developmental dysfunction and specific learning disabilities were assessed in the retrospective study in the group of 56 school-aged twins. The relationships between genetic, perinatal and social factors and learning disability were also determined. It was found that 12.5% of twins had learning disabilities. The most common neurodevelopmental dysfunction were language disorders, poor graphomotor fluency and poor fine motor dexterity. It was also found that educational difficulty were associated with prematurity, low Apgar scores, neonatal complications and familial predisposition.

[Frequency of goiter in children and adolescents in the Szczecin region].
The study was carried out in 2153 children and adolescents (1066 girls and 1087 boys) aged 5-20 years. The examined group was chosen randomly, according to a simple drawing scheme. The aim of the study was to evaluate frequency, size and character of goiter in developmental age population in Szczecin's region. The goiter was found in 14% of examined population (18.4% in girls and 9.8% in boys). Frequency of goiter approximated to 37% in girls and 16% in boys during puberty spurt (between 10 and 16 year of age). Small degree of thyroid enlargement was predominant in examined population. Large goiter was present more frequent in girls than in boys. We did not find clinical symptoms of thyroid gland dysfunction in examined group. Frequency of nodular goiter was 7% of children's and adolescent's population with higher incidence in boys (9%) than in girls (6%).

[Effectiveness of iodine prophylaxis and frequency of thyroid enlargement (thyroid goiter) and clinical diagnosis of thyroid diseases in inhabitants of the Szczecin region after the Czernobyl accident].
The study, supported by program MZ-XVII, was carried on 4567 inhabitants of the area of Szczecin (2350 females and 2217 males). The population was chosen randomly, according to a simple drawing scheme. All subjects were clinically examined using standardised questionnaires. In 3468 persons (including 1807 girls and women, 1661 boys and men) apart form clinical examination, the assessment of thyrotropin, thyroxine and triiodothyronine in serum and frequency of antithyroglobulin antibodies and antithyroid membrane antibodies were evaluated. The data indicate that 94% of children in Szczecin's region received the prophylactic dose of iodine, mostly between the 1st and the 5th of May 1986. Only 17% of the adults received iodine. The most common preparation was Lugol solution given in a single dose. Among all persons who received iodine, only in 5% of subjects the side effects were noted (mostly in children), including symptoms of gastrointestinal tract (vomiting, abdomen pain) and occasionally intrathyroid side effects (thyroid pains). In examined population the high frequency of thyroid enlargement, mainly in women (up to 43-44% at the age group 30-50 years) was found. The frequency of clinical diagnosis of thyroid disease was higher in women than in man (most often the diffuse goiter, rarely the nodular goiter). The frequency of thyroid enlargement and clinical diagnosis of thyroid disease was not dependent on prophylactic iodine intake. The iodine prophylaxis did not influence on thyroid hormones and TSH serum levels and on frequency of antithyroid antibodies.

[Frequency of thyroid enlargement (goiter) in residents of the Szczecin region].
The study has been carried out on 4,565 persons (2,349 girls and women also 2,216 boys and men) aged 4-64. The examined group was chosen randomly, according to a simple drawing scheme. The aim of the study is to evaluate frequency, magnitude and character of goiter in residents in Szczecin region. The goiter has been found in 19.5% persons in examined population, so it makes possible an endemic state. In consideration of a fact that goiter appears frequently among women and there are more cases of thyroid enlargement (O-B and I degree), as well as a small number of people with disturbance thyroid function only slightly endemic character is stated. Because the frequency of modular goiter among people with goiter is 20% it doesn't express extent of endemic state.
