- BACKGROUND: The prevalence of thyroid disease is increased in Down's syndrome. Most available data come from cross sectional studies. AIMS: To study longitudinally thyroid function in patients with Down's syndrome in Uppsala county (85 patients) up to the age of 25 years. METHODS: Observational study based on yearly follow up in a children's clinic. Thyroid function tests were performed at each visit to the clinic. RESULTS: Hypothyroidism was found in 30 and hyperthyroidism was found in two of the 85 patients. No sex difference was seen. Half of the patients with hypothyroidism acquired the condition before the age of 8 years, but only one of them displayed thyroid autoantibodies at diagnosis. Most patients who developed hypothyroidism after this age had thyroid autoantibodies. In the prepubertal patients with hypothyroidism, growth velocity was lower during the year before the start of thyroxine treatment than during the year after treatment began; it was also lower than that of sex and age matched euthyroidic children with Down's syndrome. CONCLUSION: Thyroid dysfunction in patients with Down's syndrome is common in childhood. Consequently, annual screening is important. Autoimmune thyroid disease is uncommon in young children with Down's syndrome but is common after 8 years of age.

- The spontaneous growth process in Turner's syndrome is characterized by a progressive decline in height velocity during childhood and no pubertal growth spurt. Therefore, therapy aimed at improving height during childhood as well as increasing final height is desirable for most girls with Turner's syndrome. Forty-five girls with Turner's syndrome, 9-16 yr of age (mean age, 12.2 yr), were allocated to three study groups. Group 1 (n = 13) was initially treated with oxandrolone alone; after 1 yr of treatment, GH without (group 1a; n = 6) or with (group 1b; n = 7) ethinyl estradiol was added. Group 2 (n = 17) was treated with GH plus oxandrolone. Group 3 (n = 15) was treated with GH, oxandrolone, and ethinyl estradiol. The dosage were: GH, 0.1 IU/kg.day; oxandrolone, 0.05 mg/kg.day; and ethinyl estradiol, 100 ng/kg.day. A height of 150 cm or more was achieved in 61%, 75%, and 60% of the girls in groups 1, 2, and 3, respectively. The most impressive increase in height was seen in group 2. In this group the mean final height was 154.2 cm (SD = 6.6), which is equivalent to a mean net gain of 8.5 cm (SD = 4.6) over the projected final height. In group 3, in which ethinyl estradiol was included from the start of therapy, the initially good height velocity decelerated after 1-2 yr of treatment. Their mean final height was 151.1 (SD = 4.6) cm, equivalent to a mean net gain of 3.0 cm (SD = 3.8). A similar growth-decelerating effect of ethinyl estradiol was seen in group 1b. We conclude that in girls with Turner's syndrome who are older than 9 yr of age, treatment with GH in combination with oxandrolone results in significant growth acceleration, imitating that in normal puberty, leading to a more favorable height during childhood. This mode of treatment also results in a significantly increased final height, permitting a great number of the girls to attain a final height of more than 150 cm. However, early addition of estrogen decelerates the height velocity and reduces the gain in height.

Relations between age, metabolic control, disease adjustment and psychological aspects in insulin-dependent diabetes mellitus

- The relations between age, metabolic control, disease adjustment, and psychological factors in boys and girls with recently diagnosed insulin-dependent diabetes mellitus (IDDM) were studied. Older girls had significant higher postremission glycosylated haemoglobin A (Hb AIc) levels (p = 0.008). Girls with more hospitalizations had a lower developmental level (p = 0.05), and had significantly more problems in the behavioural rating (p = 0.05). Boys with more hospitalizations had a more external locus of control (p = 0.01), more difficulties with disease adjustment, more emotional problems, and were also clinically assessed as having more behavioural problems. Boys showing more difficulties in psychological adjustment to the disease also had higher postremission Hb AIc levels (p = 0.02). Although Swedish children with IDDM of short disease duration do not differ from healthy children in important psychological aspects, older girls and a small group of problematic younger boys are at risk of developing metabolic imbalance after a short disease duration.

- OBJECTIVE: This study was designed to determine whether a relationship exists between previous exposure to measles, mumps, and rubella (MMR) by natural infection or vaccination or by new immunization with MMR vaccine, and either the presence or levels of autoantibodies against thyroid cell and pancreatic beta-cell antigens. METHODS: Antibodies against MMR and autoantibodies against thyroglobulin, thyroid peroxidase, pancreas islet cells (ICA), islet cell surface, glutamic acid decarboxylase 65k autoantibodies, and insulin were studied before, and 3 months after, vaccination with combined MMR vaccine in 386 school children between 11 and 13 years of age. RESULTS: The vaccination changed neither the prevalence nor the level of autoantibodies. Children with rubella antibodies before vaccination had higher levels of ICA than did the rubella seronegative children. In contrast, thyroid autoantibody levels and prevalence were lower in children with antibodies against measles, mumps, or both before vaccination than in children without those antibodies. CONCLUSIONS: Previous natural infection or vaccination against measles, mumps, or both seemed to have an inhibitory effect on the development of thyroid autoantibodies. In contrast, children with previous exposure to rubella had higher levels of ICA. No evidence was found that MMR vaccination during adolescence may trigger autoimmunity.

- A case of bilateral nonpalpable testes is described. Ultrasonography showed no testis. Laparoscopy revealed no intraabdominal testis, vas or vessels. Human chorionic gonadotrophine test suggested the presence of testicular tissue Computed tomography showed a testis present in each inguinal canal. Inguinal exploration confirmed the finding. This case stresses the importance of careful interpretation of the laparoscopic findings together with other diagnostic methods in localizing testicular tissue in patients with nonpalpable testes.

- BACKGROUND: The purpose of this study was to evaluate the ultrasound technique for measuring subcutaneous adipose tissue in infants. METHODS: Twenty infants were investigated at 3, 6, and 12 months of age. All measurements were made by the same investigator in triplicate on the left side of the body at the triceps and subscapular anatomic landmarks and at the abdomen and thigh. An ultrasound system equipped with a linear 7.0-MHz transducer was used. RESULTS: The intraclass correlation coefficients were 0.88 to 0.99. Random errors ranged from 0.01 to 0.19 mm. For log-transformed values, the random error ranged from 2.4% to 5.7%. CONCLUSIONS: Measurements of subcutaneous fat in infants using ultrasound are reproducible when performed by the same observer.
