Abstract
With regard to their thyroid function, somatic and intellectual development, we compared 17 children of 13 hyperthyroid mothers (group I) receiving antithyroid drug treatment during their pregnancies with 25 children of 15 mothers who were euthyroid without any antithyroid treatment during their pregnancy (group II). Mean duration of maternal treatment was 3.5 months in group I, using carbimazole or thiamazole (N = 12) and propylthiouracil (N = 1). Age at examination in group I was 7.2 +/- 6.2 years, in group II 8.7 +/- 7.1 years (mean +/- SD). Both groups showed no significant differences in the results of the clinical examination and in the degree of their mental and psychomotoric development at the time of study. We found the mean birth weight of the infants in group I significantly lower than in group II (3165 +/- 339 vs 3666 +/- 670 g, p less than 0.03). The individual birth weights, however, were normal for gestational age. The body weight difference between groups disappeared during the further somatic development of the children. The serum concentration of free thyroxine in group I was significantly higher than in group II (17.2 +/- 2.4 vs 14.9 +/- 1.9 pmol/l, p less than 0.003), but fell in both groups within the normal range. The evaluation of the psychomotoric and intellectual capacity of the children at different developmental stages showed no abnormalities detectable by our tests. Thus, in the children of the two groups we found no adverse effects of a maternal antithyroid drug treatment during pregnancy or of inactive maternal Graves' disease alone, neither on thyroid gland size and function nor on the physical or intellectual development, after the neonatal period.

Abstract
The testing of a SCN- dose (32 mg NaSCN/kg oral 21 d long) which is about 100 fold above the alimentary SCN(-)-uptake on guinea pig has shown neither histologic/morphometrical nor clinical clue to thyrostatic effect. In 6 regions of the GDR (1,349 persons) has not been secured epidemiologically any relationship between SCN- serum level as well as SCN- urine level and goiter. The partly in the tendency low increase of SCN- level by patients with bland goiter was always under the levels of smokers without goiter, exceeded indeed the threshold of significance in the area of Werdau. In the industrial agglomeration areas the I(-)-SCN(-)-quotient at the most unfavourable cases ran to 3.5 (Halle, smoker, struma), was consequently close to the critical level of the goiter risk.

Abstract
The prevalence of arterial hypertension was evaluated in a retrospective study of 158 patients with acromegaly, and results were compared to control populations, namely, the Munich Blood Pressure Study (MBPS) and the Framingham Study. The prevalence of hypertension (defined according to WHO criteria) was significantly increased in female patients but not in men; hypertensive acromegalics were older and tended to have higher body weight compared to normotensive patients. Hypertension was not related to serum concentrations of growth hormone. After successful treatment of acromegaly, growth hormone levels and systolic and diastolic blood pressure fell only in female hypertensive acromegalics; this did not occur in normotensives. The rise in plasma renin activity in response to upright posture was diminished in 57.9% of acromegalic patients. The prevalence of low-renin hypertension in our group of patients was 31.6%, which is similar to figures reported for unselected non-acromegalic subjects with essential hypertension. Orthostatic renin activity was weakly and inversely related (r = -0.3) to blood pressure. No relationship between plasma aldosterone concentration and blood pressure could be detected; however, in acromegalic women, aldosterone rose higher after ambulation than in men. In conclusion, hypertension is a common problem in acromegaly and at least in part related to similar risk factors in control populations. The association with abnormalities of the renin-angiotensin-aldosterone system is difficult to interpret and does not offer an explanation for the slight increase in the prevalence of hypertension.

Abstract
Graves' disease is an autoimmune disease whose development involves immunogenetic and exogenous factors such as viruses, bacteria and iodine excess. In a number of patients the disease follows a chronic recurrent course. A recurrence rate of 50% can be expected one year after the end of therapy. Based on the preliminary results of the prospective study presented here, this recurrence rate does not differ in groups where patients underwent long-term treatment with 10 or 40 mg thiamazole. Retrospectively obtained data suggest that the time at which euthyroidism occurs under low-dose treatment is dependent on the alimentary iodine supply. A number of groups have attempted to develop clinically applicable methods to identify patients at risk for recurrence at the end of treatment. All the studies yielded controversial results. A prospective multicenter study was undertaken to reinvestigate the importance of measuring TSH receptor antibodies and performing the TRH test and the suppression test at the end of therapy in connection with this problem. In 451 patients the recurrence rate was 50.3% one year after the end of treatment. The patients in the recurrence group had a significantly higher rate of persistent antibody activity, no increase in TSH after TRH (negative TRH test), no normal suppressibility of thyroid 123 iodine uptake (negative suppression test) and larger goiter. The calculation of sensitivities and specificities shows, however, that these differences are not large enough to be of clinical importance for the individual patient.

Abstract
To investigate the adrenostatic potential of a nonhypnotic low dose etomidate infusion, we administered 0.03 mg/kg etomidate in a bolus injection, followed by constant infusion of 0.3 mg/kg.h for 24 h to 6 patients with severe Cushing's syndrome. The dose-response relationship also was determined in 15 normal subjects. Three groups of 5 received, respectively, doses of 0.03, 0.1, and 0.3 mg/kg.h etomidate for 5 h after an initial bolus dose of 0.03 mg/kg. The response to exogenously administered ACTH [0.25 mg ACTH-(1-24)], injected after the etomidate or control infusion, was determined in all normal subjects. In the six hypercortisolemic patients, serum cortisol concentrations decreased from 1374 +/- 436 nmol/L (mean +/- SEM) to 188 +/- 91 nmol/L after 11 h of etomidate infusion and remained low until the end of the infusion. Cortisol levels returned to pretreatment concentrations by 24 h. Excretion of urinary free cortisol decreased from 1180 +/- 196 to 185 +/- 66 nmol/day. In the normal subjects, administration of etomidate led to a dose-dependent decrease in serum cortisol from about 550 to 83 nmol/L, while 11-deoxycortisol rose from low or undetectable levels up to 346 nmol/L. In response to ACTH, cortisol levels rose in inverse proportion to the etomidate dose. It was, however, significantly reduced compared to normal saline infusion even after the lowest dose. Changes in aldosterone and corticosterone concentrations were similar to those in cortisol, and 11-deoxycorticosterone changed in a pattern similar to that of 11-deoxycortisol. Two of five normal subjects reported tiredness during the highest etomidate infusion. No other side-effects were noted. We conclude that iv administered etomidate in a low nonhypnotic dose reduces serum cortisol concentrations in a dose-dependent manner in both hyper- and eucortisolemic subjects. This study suggests that etomidate at a dose of 0.1 mg/kg.h or lower may be an effective strategy for the control of severe hypercortisolemia.

Abstract
Nine hundred thirty-two patients with papillary and follicular thyroid carcinomas were seen at the Departments of Medicine, Surgery, and Radiology of the University of Essen, Essen, Germany, between 1970 and 1986. In addition to standard treatment by surgery, radioactive iodine and medical thyroid stimulating hormone (TSH) suppression, 346 patients had received conventional external irradiation to the neck (mostly 40-60 Gy) before referral to our institutions, whereas 586 patients had not received radiotherapy. From the follow-up data of these patients, survival rates were calculated separately for tumor Stages T1 (n = 203), T2 (n = 552), and T3/T4 (n = 277) using life-table analysis. Distribution of risk factors (histologic type of tumor, grading of malignancy, presence of distant metastases, age and sex) was similar in all groups with the one exception, that the radiotherapy patients with Stage T3/T4 were older. There was no significant difference in the life expectancy of irradiated and not irradiated patients by Breslow and Mantel-Cox tests. In Stages T1, T2, and T3/T4, 75% of the radiotherapy patients survived for 10.6 +/- 0.32, 11.5 +/- 0.61, and 6.71 +/- 0.85 years, respectively; the figures for the nonirradiated patients were 9.4 +/- 0.17, 10.8 +/- 0.37, and 6.26 +/- 0.51 years, respectively. When survival rates were calculated separately for patients with Stage T3/T4 older and younger than 40 years, there was no obvious effect of radiotherapy in the younger group, whereas in the older patients, improvement of survival by radiation just failed to reach statistical significance (P less than 0.09). In conclusion, this retrospective analysis failed to prove that survival is prolonged in patients with differentiated carcinoma by administration of conventional external radiotherapy after surgery. A benefit to older patients with locally advanced tumors has still to be demonstrated.

Abstract
Initial symptoms of thyroid cancer were collected and analysed for 1116 patients with thyroid cancer in an iodine-deficient region, retrospectively for the period 1960-80 (604 patients), prospectively for 1981-87 (512). Using the WHO classification, 56.1% of patients had papillary, 32.7% follicular, 4.8% C-cell, 3.7% anaplastic and 2.7% various other malignant tumours. In 40% of all patients the initial sign had been a solitary intrathyroid nodule. Cervical lymph node swelling as initial sign had been significantly more frequent in men (21.1%) than in women (10.3%; P less than 0.003). In patients aged under 40 years the cervical lymph node signs were three times as common as among those over 50 years. Distant metastases as initial sign of papillary carcinoma were seen only in those over 60 years. Tumour stages T3 and T4 were seen significantly more frequently in over 60-year-old (42.2%) than under 40-year-old (25.1%; P less than 0.001), independent of histological type. Composition and initial signs of this patient cohort in an iodine-deficient region differed only slightly from those in an iodine-rich region.

Abstract
Side effects of antithyroid treatment were retrospectively analysed in 1256 patients with hyperthyroidism. Overall rate of side effects was 14.3%. Skin reactions were the most frequent ones (5.6%), followed by arthropathies (1.6%). The incidence of agranulocytosis was 0.14%. Median duration of all side effects was 1.5 months. In half the cases the side effects were controllable so that treatment was continued, although at a changed dosage. The rate of cross-reaction between carbimazole and thiamazole, on the one hand, and propylthiouracil, on the other, was 13.8% and 15.2%, respectively. The side effects became apparent after a mean of one month's treatment, almost always (in 97.1%) within the first year of treatment. There was a significant dose dependence for an initial thiamazole dose of over 20 mg (relative side effect risk of 2.3), and for an initial dose of over 30 mg for carbimazole (relative side effect risk of 1.6). Although most side effects were not dangerous, in normal instances the lowest possible dosage should be administered to control hyperthyroid metabolism. Long-term treatment with low doses seem to be without problems.

Abstract
TSH binding-inhibiting antibody (TBIAb) activity was measured in 809 European patients with different forms of hyperthyroidism. Distribution of these TBIAb was skewed, with a peak in the range of normal controls, and an ill defined, not clearly separated peak at higher levels of TSH displacement. There was no unequivocal separation of two possible subgroups of hyperthyroidism (immunogenic and non-immunogenic). TBIAb distributions of patients with and without endocrine ophthalmopathy (EO) overlapped considerably. Although patients with Graves' disease, arbitrarily defined by the presence of endocrine ophthalmopathy or diffuse nuclide uptake by thyroid scanning, had mostly elevated TBIAb activity, 24.3% had values within the range of normal controls (mean + 2SD). Patients with diffuse thyroid uptake had significantly higher TBIAb levels than patients with nodular scan findings. In Graves' disease, TBIAb activity was positively correlated with the severity of endocrine ophthalmopathy, the size of the thyroid, and the serum levels of total and free triiodothyronine. There was no influence of age, sex, pretreatment, or regional iodine supply. These results suggest (1) that the clinical manifestations of Graves' disease are statistically related to TBIAb activity and (2) that separation of immunogenic and non-immunogenic forms of hyperthyroidism by means of TBIAb determination is unsatisfactory. The almost continuous distribution of TBIAb points to insufficient sensitivity of the present technique and raises doubts as to whether TBIAb values can be reliably classified as 'positive' or 'negative'.

Abstract
Twenty-three patients (13 females, 10 males) with panmyelopathy (N = 9), chronic leukemia (N = 5), and acute leukemias (N = 9) were studied 1 to 6 years following allogenic bone marrow transplantation. All patients had received conditioning treatment with cyclophosphamide prior to aBMT, and 2 of the patients with bone marrow aplasia and all of the leukemia patients had been given radiotherapy. An endocrine assessment was performed by means of TRH, GnRH, oCRF and GHRH tests and estimation of thyroid and gonadal hormones. Whereas pituitary-adrenal function appeared to remain stable, there was a 17.4% incidence of subclinical hypothyroidism (25% of the irradiated patients). Growth hormone reserve was diminished, and ovarian failure occurred in all female patients after radiotherapy, whereas in the men, only a moderate elevation of gonadotropins was observed. Our results warrant observation of thyroid and gonadal function, and in children of growth hormone secretion, after allogenic bone marrow transplantation. They also show that replacement therapy may be needed in some patients.

Abstract
Human adrenal microsomes have been labelled with 125I and immunoprecipitated with sera from patients with Addison's disease. The immunoprecipitates were then analysed by SDS-PAGE and autoradiography. 13 of the 23 sera from the Addison patients studied contained antibodies which reacted with a 55 kDa adrenal microsomal protein. The same 13 sera were also positive for adrenal antibodies as judged by immunofluorescence. The 55 kDa protein was not immunoprecipitated from placenta or thyroid microsomes by Addison sera. Furthermore, patients with Graves' disease or rheumatoid arthritis did not immunoprecipitate the 55 kDa protein from adrenal microsomes. Our studies suggest therefore that Addison sera contain antibodies to a 55 kDa adrenal specific protein which may well be the antigen observed on immunofluorescence.

Abstract
Fifty-three patients with subacute thyroiditis (SAT) were seen during the acute stage of the disease. HLA-Bw 35 was positive in 33 out of 39 tested patients. At first presentation, all examined patients (N = 23) had ultrasound abnormalities (generalized hypodensity, single or multiple hypodense areas). Serum T4 and/or T3 were increased in 24/52, free T4 in 11/23, and the TSH response to TRH was flat in 8/11 patients. Six of 12 in whom volumetry was performed had goitres. Thirty-seven patients were re-examined after a mean follow-up interval of 46.5 months. At this follow-up, serum T4, free T4 and T3 levels as well as the sonographically determined thyroid volume had decreased, but there was still abnormalities by ultrasound detected in 14/36 patients; 19.4% had focal sonolucent lesions, whereas the prevalence of such lesions was only 3.1% in asymptomatic controls. Three patients were subclinically hypothyroid at the follow-up, whereas all others were euthyroid. Patients with abnormal ultrasound findings were of the same age and had a similar thyroid size, but a slightly higher TSH and a significantly (P less than 0.02) lower free T4 than those with normal ultrasound findings. They also had a higher prevalence of thyroid autoantibodies in low titres. Serum thyroglobulin was elevated in more than half of the patients during the acute phase, but only in 1 out of 11 patients during follow-up. Thyroglobulin at the follow-up was not related to TSH, but there was a correlation with thyroid volume (r = 0.57).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The epidemiological data of thyroid carcinoma are difficult to evaluate. Several variables influence the biologic behaviour and the great number of occult papillary carcinomas obscure the picture. Among our 1116 patients we found as first symptoms solitary nodules in 41,4% being localized in differentiated carcinomas significantly more frequently in the right than is the left lobe. Multinodular goiter was seen in 24,2%, cervical lymph nodes in 10,9% and distant metastases in 3,2%. In medullary carcinoma cervical lymph nodes were seen in 27% and thus the second most frequent leading symptom. Together with sonography, thyroid scan and fine needle biopsy it is possible today to assure preoperatively at a high degree the diagnosis. A differentiated therapy is generally applied taking into account the particular prognosis of the patient, especially in papillary carcinoma. A more radical initial treatment is necessary in follicular carcinoma. In medullary carcinoma only the thyroidectomy without radiation has been proven as effective means.

Abstract
In a prospective multicentric study, 924 untreated hyperthyroid patients were investigated, coming consecutively within one year into 17 thyroid centers of 6 European countries. With the aid of clinical information, evaluation of thyroid scan and centrally assayed thyroid hormones, thyroid antibodies, TSH-binding inhibiting immunoglobulins (TBII), and urinary iodine, different types of hyperthyroidism could be shown. Two types of hyperthyroidism could be defined directly: autonomous adenoma in cases of hot nodules in thyroid scan and Graves' disease, defined as hyperthyroidism with eye symptoms, and/or measurable TBII levels. The remainder, called "non-classifiable", included TBII negative Graves' patients, comprising of Hashitoxicosis, toxic nodular goiter, and other multifocal autonomies. 9.2% of the patients had an autonomous adenoma, 59.6% Graves' disease, and 31.2% unclassified hyperthyroidism. The main and significant difference between these types were mean age, goiter size, nodularity, and severity of the disease, being especially expressed in Graves' disease. Graves' patients had significantly increased T3/T4 ratios. Using as additional criteria diffuse regular uptake and/or increased T3/T4 ratios for immunogenic types of hyperthyroidism at least half of the 31.2% unclassified hyperthyroidism are probably Graves' disease. Forming two groups of iodine-deficient areas (IDA) and iodine-sufficient areas (ISA) according to the urinary iodine, it was possible to elucidate some characteristics independently of local factors. Autonomous adenoma was more frequent in IDA (10.1%) than in ISA (3.2%). Differences in iodine supply are reflected in the three types of hyperthyroidism by a significant higher prevalence of goiter, thyroid nodularity, lower thyroid hormone concentrations, and a higher rate of T3 toxicosis in IDA.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Bilateral, selective and simultaneous catheterization of the inferior petrosal sinus with measurements of ACTH after stimulation with ovine corticotrophin-releasing factor (CRF) is now frequently used to establish the differential diagnosis in patients with Cushing's disease and to determine the side of the microadenoma in the pituitary. To investigate whether CRF has any effect on other pituitary hormones, we also determined prolactin (PRL) concentrations in the samples obtained during this procedure. Fourteen patients under evaluation for Cushing's syndrome and one patient with a hormonally inactive pituitary tumour were catheterized. Baseline PRL levels in the peripheral veins were within the normal range before and after CRF in all patients (3.7-16.0 ng/ml). In 10 patients ACTH- and PRL concentrations lateralized to one side of the pituitary and could both be stimulated by CRF. The gradient of PRL between inferior petrosal sinus and periphery ranged from 7 to 147 ng/ml after CRF. There was no correlation between ACTH and prolactin increase in response to CRF. In three patients with no ACTH-gradient but a positive response to CRF, no tumours could be found during transsphenoidal surgery; they had no PRL-gradient and showed no PRL response to CRF. One patient with the ectopic ACTH syndrome had no ACTH- and no PRL response to CRF. The patient with the inactive pituitary tumour showed a normal ACTH-, but no PRL response to CRF. These data demonstrate for the first time that in normo-prolactinaemic patients with Cushing's disease, in contrast to patients bearing no microadenoma, PRL is secreted in response to CRF.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Treatment of tuberculosis with rifampicin in patients with pre-existing adrenal failure has been reported to induce adrenal crisis due to alteration of cortisol metabolism by induction of hepatic mixed liver oxygenase enzymes. To determine whether mineralocorticoid metabolism is altered by rifampicin treatment, we established the pharmacokinetics of immunoreactive aldosterone. The metabolic clearance rate (MCR) and plasma half-life of this material were measured before and after 6 days of rifampicin treatment (600 mg/day) in seven patients with Addison's disease due to tuberculosis. Antipyrine clearance and urinary 6-beta-hydroxycortisol excretion was determined to demonstrate induction of the cytochrome P450 dependent enzymes. Infusion of aldosterone at a constant rate of 0.17 mg/h over 4.5 h produced steady state concentrations after 2 h, with no difference before and after rifampicin treatment (mean +/- SD, 1649 +/- 144 vs 1586 +/- 80 pg/ml, respectively). The disappearance curve of IR-aldosterone from plasma was biexponential. No change could be observed in the plasma half-lives (alpha-phase 29 +/- 1.9 min vs 30 +/- 1.5 min, beta-phase 129 +/- 3.2 min vs 126 +/- 4.3 min), the MCR (1.47 +/- 0.1 l/h/kg vs 1.46 +/- 0.1 l/h/kg), and the volume of distribution (9.9 +/- 1.9 vs 10.2 +/- 0.3 l). The antipyrine half-life decreased significantly from 12.2 +/- 2.6 h to 7.6 +/- 0.9 h (P less than 0.05) with a rise in antipyrine clearance from 0.38 +/- 0.07 to 0.80 +/- 0.23 ml/min/kg (P less than 0.05) and no change in the volume of distribution.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
ACTH concentration was measured in simultaneously drawn blood samples from the left and right inferior petrosal sinuses before and after administration of corticotropin-releasing hormone (CRH). Such samples were successfully obtained in 20 of 21 patients with ACTH-dependent Cushing's syndrome on whom it was attempted. In 11 of the 20 patients there was no concentration difference between petrosal sinus and peripheral blood. But 13 of 19 patients had a unilateral central to peripheral concentration gradient greater than 1.4 after CRH administration. In the other six patients no ipsi- to contralateral gradient was demonstrable. Two of these patients had a proven ectopic ACTH-producing tumor; no adenoma was found at operation in three; on patient is awaiting operation. In 10 of 13 patients with unilateral gradient a microadenoma was found on the same side at operation. One patient had a hemi-hypophysectomy on the side of the higher gradient: hypocortisolemia developed in her postoperatively. Two other patients are awaiting operation. The results indicate that simultaneous bilateral catheterization of the inferior petrosal sinus with CRH stimulation is a highly informative examination with few side-effects and will contribute to better diagnosis and treatment of Cushing's syndrome.
