Endocrine abnormalities in patients with adrenal tumours incidentally discovered on computed tomography.

To determine endocrine activity of adrenal tumours incidentally discovered on C.T., we examined 20 consecutive patients. They underwent thorough hormonal assessment and scintigraphic scanning with radioactive cholesterol under dexamethasone suppression (19 patients). Biochemical findings compatible with cortisol hypersecretion were detected in 5 patients. One patient had reduced reserves of cortisol secretion and one had hyporeninemic hypoaldosteronism. The scintigraphy showed no uptake in 10, unilateral uptake in 4, and bilateral uptake in 5 patients. In 3 patients the finding was unilateral on CT. but bilateral on scintigraphy. Signs of autonomous cortisol production were more common among patients who had uptake on scintigraphy. At the operation of 8 patients only benign lesions were found. During the follow-up (9 to 49 months) of the 12 unoperated patients, the tumour disappeared in one and remained unchanged in the others. No changes occurred in the biochemical findings except in one patient whose cortisol response to 1 mg of dexamethasone became abnormal. Since slight hypercortisolism or a bilateral disease often exists behind an incidentally discovered adrenal tumour, we emphasize the importance of careful assessment of cortisol metabolism and a scintigraphic scanning under dexamethasone suppression in the examination of these patients.

High frequency of coeliac disease in adult patients with type-I diabetes.

Anti-reticulin antibodies were measured by an indirect immunofluorescence method in 195 consecutive patients with insulin-dependent diabetes mellitus, and positive titres were found in 8 patients. A jejunal biopsy was performed in these patients, all of whom had small-intestinal atrophy. Thus the frequency of coeliac disease in adult diabetes patients was 4.1%. The patients had no signs of malabsorption or of significant abdominal complaints. We conclude that coeliac disease is commoner in type-I diabetes than in the normal population, and measurement of anti-reticulin antibodies seems to be a suitable screening method.

Comparison between lovastatin and gemfibrozil in the treatment of primary hypercholesterolemia: the Finnish Multicenter Study.

A randomized, double-blind 12-week comparison of lovastatin and gemfibrozil in the treatment of patients with primary hypercholesterolemia with normal or moderately elevated triglycerides was performed in 334 patients from 19 centers in Finland. Patients with "high" total serum cholesterol (240 to 300 mg/dl) constituted Stratum 1 and patients with "very high" total serum cholesterol (greater than 300 mg/dl) constituted Stratum 2. In Stratum 1, patients were randomly assigned to either lovastatin 20 mg nightly or gemfibrozil 600 mg twice daily, and in Stratum 2 to either lovastatin 40 mg nightly or gemfibrozil 600 mg twice daily. In both strata, the lovastatin dose was doubled after 6 weeks if serum cholesterol remained greater than 200 mg/dl. Ninety-two and 93% of the patients doubled their dose in Strata 1 and 2, respectively, resulting in average doses of 38.5 mg/day (Stratum 1) and 77.4 mg/day (Stratum 1) and 77.4 mg/day (Stratum 2) by week 12. The dose of gemifibrozil was kept constant. Lovastatin reduced low-density lipoprotein (LDL) cholesterol by 31 and 42% in Stratum 1 and 2, respectively. The corresponding reductions achieved by gemfibrozil were 13 and 18%. In both strata, as well as in patients with Type IIa and IIb hyperlipoproteinemia, lovastatin was approximately 2 to 4 times as effective as gemfibrozil in lowering LDL cholesterol. Although both drugs increased high-density lipoprotein (HDL) cholesterol concentrations, gemfibrozil was 1.5 to 3 times more effective. LDL/HDL cholesterol ratios decreased significantly more during lovastatin therapy. Both drugs reduced serum triglyceride levels, but gemfibrozil was much more effective.(ABSTRACT TRUNCATED AT 250 WORDS)

Adrenal pheochromocytoma-ganglioneuroma producing catecholamines and various neuropeptides.

A 65-year-old woman presenting with back pain, difficulties in walking and watery diarrhea. A right adrenal tumor and high excretion of catecholamines were found. Laboratory examinations showed raised levels of vasoactive intestinal polypeptide, pancreatic polypeptide, gastrin and calcitonin. Histology showed a combined pheochromocytoma-ganglioneuroma. The neoplastic cell population was immunohistochemically shown to contain tyrosine hydroxylase, neuropeptide Y, met-enkephalin, substance P, vasoactive intestinal polypeptide, calcitonin and calcitonin gene-related peptide. Postoperatively, the patient recovered fully and the hormone levels returned to normal.

Human epidermal growth factor concentrations in urine, but not in saliva and serum, depend on thyroid state.

To evaluate the effects of thyroid hormones on the concentration of epidermal growth factor (EGF), we determined values for the immunoreactive EGF concentration in the urine (U-irEGF) of newborn infants with congenital hypothyroidism (N = 19), and in urine, saliva and serum of adult patients with hypothyroidism (N = 11) and hyperthyroidism (N = 8). The values were expressed as SD score (SDS), i.e. deviation in SD units from their mean value of healthy subjects of the same age and sex. The SDS of relative U-irEGF (ng/mg creatinine) was lower (P less than 0.01) in newborn infants with congenital hypothyroidism (-0.8 +/- 0.2; mean +/- SEM) than in healthy infants. Their relative U-irEGF correlated with their serum T4 concentrations (r = 0.59, P less than 0.01). The SDS of relative U-irEGF was lower (P less than 0.01) in adult hypothyroid patients (-1.2 +/- 0.5) and higher (P greater than 0.05) in adult hypothyroid patients (0.9 +/- 0.6) than in healthy adult subjects. When subsequently euthyroid, their SDS of relative U-irEGF increased to -0.5 +/- 0.3 (P less than 0.01), and decreased to -0.7 +/- 1.1 (P less than 0.05), respectively. The irEGF concentrations in saliva and serum were not significantly different between the hypothyroid and hyperthyroid patients. Our results indicate that urinary excretion of irEGF in man is dependent on thyroid hormone.

Visible corneal nerve fibers and neuromas of the conjunctiva--a syndrome of type-3 multiple endocrine adenomatosis in two generations.

A case report of multiple mucosal neuroma syndrome (multiple endocrine adenomatosis type 3) is presented in a mother and her two children. In all of them the eye involvement consisted of highly visible corneal nerves, neuromas of the conjunctiva, and thickened eye lids. The mother had mucosal neuromas of the tongue, and in the 4-year-old girl these were seen to appear during the follow-up period. The mother and children had medullary carcinoma of the thyroid. Marfanoid physiognomy was also one characteristic clinical feature.

Dermatitis herpetiformis and celiac disease associated with Addison's disease.

We treated two patients with dermatitis herpetiformis and Addison's disease, and one patient with celiac disease without the rash, but with Addison's disease and juvenile diabetes. In two of the patients, the concomitant diseases also included a thyroid disease. The predisposing factors to the multiple endocrine disorders in these patients with gluten-sensitive skin and/or small intestinal disease remained unknown. Two of the three patients had HLA-B8, none was known to have affected relatives, and the Addison's disease appeared before, at the same time, or after the patients contracted dermatitis herpetiformis or celiac disease.

Vitamin D deficiency in women with femoral neck fracture.

Calcium (Ca) metabolism, with particular reference to serum vitamin D metabolites, was investigated in 40 women with femoral neck fracture (mean age 77.1 +/- 8.6 yr). All the patients were ambulant before the fracture; eight were long-term geriatric in-patients. Serum total and ionised calcium and serum albumin levels were significantly lower, and serum parathormone (PTH) levels significantly higher in fracture patients than in controls. Both serum 25-OH-D and 1,25-(OH)2D were significantly lower in fracture patients than in controls. We concluded that vitamin D, serum PTH and calcium levels should be checked with greater frequency in patients at high risk for osteoporosis and osteomalacia before they reach the age of 70.

Metabolic control in adolescent insulin-dependent diabetics referred from pediatric to adult clinic.

The metabolic control of 61 consecutive cases of adolescent diabetes was followed 1 year before and 1 year after the patients were referred from a pediatric to adult clinic. The level of control of the disease was determined by measurements of haemoglobin A1 made on visits to the out-patient clinic. No significant deterioration of the disease was noted on the first visit to the adult clinic. Boys and patients with a shorter disease history coped better with the transition period. During the first year of treatment at the adult clinic the metabolic control of the disease improved significantly (p less than 0.001). Girls and diabetics with a long disease history should be well-prepared for referral to adult clinics.

Low serum oestriol and Cushing's syndrome during pregnancy.

Previously in world literature there have been reports of 40 pregnancies in women with untreated Cushing's syndrome. The perinatal mortality in these series has been 12.9%. This paper reports on a case in which low serum oestriol excretion was the first abnormal laboratory value in a patient with only a few signs of Cushing's syndrome habitus and adrenal adenoma.

Urine TRH immunoreactivity in hypothyroid and hyperthyroid patients.

Urine samples from 8 healthy subjects, from 16 patients with primary hypothyroidism and 8 patients with Graves' hyperthyroidism were pre-purified in SP-Sephadex-C-25 cation-exchange-chromatography, subjected to reverse phase high-pressure liquid chromatography (HPLC) with 0.01 M ammonium acetate pH 4 as a polar and propanol as a non-polar solvent with a 1%/min gradient and assayed in our TRH radioimmunoassay. Urine TRH-immunoreactivity levels were measured before and after 3 months of treatment with thyroxine or methimazole. The urine TRH-levels in healthy subjects were 5.5 +/- 1.4 ng/1 (mean +/- SEM, n = 8). In the hypothyroid patients, the urine TRH levels were 50.6 +/- 40 ng/1 before and 71.7 +/- 45.3 ng/1 after 3 months of treatment with thyroxine. These values did not significantly differ from those in healthy subjects. The large variations were due to highly elevated values in 3 patients. In 2 hypothyroid patients with initially high urine TRH values, 67 and 657 ng/1, urine TRH was measured 5 and 18 months later and was found to have decreased to 5 and 11 ng/1. In the hyperthyroid patients, urine TRH levels were 10.3 +/- 3.9 ng/1 before and 8.9 +/- 3.3 ng/1 after the treatment with methimazole and did not differ significantly from the levels in healthy subjects. After 3 months of treatment, the hyper- and the hypothyroid patients were euthyroid. Our results show, that, except in 2 hypothyroid patients, there does not appear to be any relationship between urine TRH levels and serum TSH or thyroid hormone levels in hypothyroid and hyperthyroid patients.

Operative management of chromophobe pituitary tumour recurrences.

Twenty-three operations were performed for recurrences of previously treated chromophobe pituitary adenomas. Eleven operations were transcranial, and 12 were transsphenoidal. Twenty-two patients were operated on because of deteriorating eyesight; this improved in ten patients, deteriorated further in three, and did not significantly change in the remaining nine patients. There was one postoperative death. The patients generally had hypopituitarism already at the time of diagnosis, and it tended to increase during treatment. The results are certainly worse than after primary operations, but there is no alternative for handling a sizeable recurrence that has already affected the optic pathways.

Recurrence of chromophobe pituitary adenomas after operation and postoperative radiotherapy.

The rate of recurrence is reported in a prospective study of 56 patients (28 men, 28 women) with large chromophobe pituitary adenoma (with or without hyperprolactinemia). The surgical approach was transfrontal in 44 and transseptosphenoidal in 12 patients. Cryoapplication was combined with the transsphenoidal operation. All but one patient received postoperative pituitary irradiation. Altogether, 11 (20%) clinical relapses (10 men) occurred between 0.5 and 6 years after the transfrontal operation. Patients that relapsed had had larger tumors than those remaining in remission. Occurrence of the tumors appeared with a deterioration of the visual field defect in 9 patients. There were no differences in the degrees of hypopituitarism in patients who relapsed as compared to patients remaining in remission.
