[Hormonal replacement therapy in women after surgery for thyroid cancer treated with suppressive doses of L-thyroxine].

Total thyroidectomy followed by 131I ablation and thyroxine suppressive therapy is recommended for the treatment of differentiated thyroid carcinomas. Thyroxine should be given at a dose sufficient to suppress TSH to low or undetectable levels. These patients are categorized as subclinical hyperthyroidism subjects. Some cardiovascular effects of subclinical hyperthyroidism, such as an increase in left ventricular mass and accelerated bone loss, should be taken into consideration. Estrogens reduce the loss of bone mass in thyrotoxic postmenopausal patients and have cardioprotective effects. The relatively high incidence of thyroid carcinoma in women suggests that estrogen and/or progesterone may be important for the development of these neoplasms. Immunohistochemical study has established that steroid receptors are present in thyroid tissue. Many authors suggest that estrogens by itself do not appear to affect the natural history of thyroid cancer. Besides the thyroid, active iodide transports catalysed by the sodium/iodide symporter occurs in the lactating mammary gland. An increased risk of breast carcinoma in women with thyroid carcinoma due to carcinogenicity of radioiodine has been reported by some but not all investigators. Hormone replacement therapy in the thyroxine treated postmenopausal women consists in conventional oral or transdermal estrogen combined with progesterone. In some cases the daily dose of thyroxine should be increased to achieve TSH suppression.

[Pregnancy in women with thyroid cancer treated with suppressive doses of L-thyroxine].

UNLABELLED: The aim of the study was to estimate the dose of thyroxine required by pregnant women who had undergone total thyreoidectomy and radioiodine treatment for thyroid cancer. Material consisted of 4 pregnant women, aged mean 30.8 years. One of patients was studied during 2 consecutive pregnancies. The daily mean dose of thyroxine was 175 micrograms. The control group consisted of 7 women with primary hypothyroidism aged mean 33.5 years, who were treated with replacement doses of thyroxine. One of them was pregnant twice. The mean daily dose of thyroxine was 106.3 micrograms. The estimation of TSH, fT4 were repeated every 4 weeks. RESULTS: In all cases natural deliveries took place. All infants were alive and had no congenital malformations and no clinical or biochemical thyroid dysfunction was found. Pregnant women treated for thyroid cancer needed to have optimized their suppressive therapy by increasing the dose of thyroxine by 26% at the first trimester, 27% at the second and 38% at the last one. Statistically significant increase was found at the 1st trimester of pregnancy and it remained at the same level till the delivery. Pregnant hypothyroid women needed to have optimized their replacement thyroxine therapy by increasing of the dose by 53% at the first trimester, by 49% at the second and by 53% at the last one. Similarly to the 1st group of patients, we noticed statistically significant increase at the 1st trimester of pregnancy. CONCLUSION: In pregnant women who have been previously treated for thyroid cancer the suppressive dose of thyroxine needs to be increased by 26-38% which is slightly less than the increase of the replacement dose in hypothyroid pregnant women.

[Results of 3-stage treatment: (I) corticotherapy, (II) linear acceleration and (III) orbital decompression in 206 patients with malignant Graves ophthalmopathy].

There is no, so far, a rational method of therapy based upon the etiology of autoimmune Graves' ophthalmopathy. As a malignant Graves' ophthalmopathy we defined the most severe eye changes leading to the sight loss or permanent disability of vision which are classified as exceeded class 3c according to the eye changes classification of the American Thyroid Association [27]. The aim of the study was to develop the most efficacious method of therapy for malignant Graves' ophthalmopathy. The material consisted of 206 patients treated according to the 3-stage method: 1-st--corticotherapy, 2-nd--radiotherapy, including linear accelerator, 3-rd--orbital decompression. Moreover, in four patients plasmapheresis was applied and in additional five cyclosporine was administered. In all 206 patients the estimation of the results of the treatment was based on the Donaldson ophthalmopathy index [4]. It has been proved that corticotherapy combined with linear accelerator radiotherapy has been the most efficacious method of treatment. It has also the least number of side effects. Orbital decompression as the 3-rd stage of treatment was employed in those cases in which the previous two stages of medical therapy were unsuccessful.

[Anaplastic thyroid carcinoma developed after treatment of "hot" thyroid nodule with radioiodine].

A case of 55 years old woman with "hot" right lobe toxic thyroid nodule, presenting with paroxysmal atrial fibrillation, and therefore treated with 131I 666MBq (18 mCi) is described. After six years she became pyrexic and suffered of severe cough proxyisms. The fine needle biopsy of the above nodule showed the presence of anaplastic thyroid carcinoma. Strumectomy followed by local radiotherapy resulted in complete disappearence of all symptoms. The microscopic of the removed thyroid tissue confirmed the above diagnosis. After 22 months' observation the patient remained in good general condition. The possible reasons for the development of the thyroid carcinoma in this case are discussed.

[Ocular hypertension in patients with infiltrative-edematous exophthalmos in Graves' disease].

The increase of the IOP--5 to 30 mm Hg--was observed in patients in whom severe infiltrative changes in the motor muscles dominated the clinical picture. Characteristic for glaucoma changes of the visual field and optic papilla were not seen, the angle was open and the outflow coefficient was in normal limits. The normalization of the IOP was obtained after decompensation of the orbits when the exophthalmos and the infiltrative changes in the motor muscles of the eye receded.
