[Differentiated thyroid carcinoma. Diagnosis and therapeutic aspects].

The significant increase in incidence of thyroid cancer in the last decade, augmented the interest in reevaluation of treatment and diagnosis methods. Those aspects let us into making this retrospective study regarding the differentiated thyroid carcinoma. The clinical material consist in 70 C.

Conventional and Doppler ultrasound in thyroid disease diagnosis.

Ultrasonography is a useful tool for diagnosis diseases of the thyroid gland. The method is reliable, inexpensive and of high diagnostic efficiency. The structural information provided by the ultrasound technique complements the results of laboratory tests and other in-vivo techniques.

Graves' ophthalmopathy.

The Graves' ophthalmopathy consists of all the pathological changes in orbital tissues, preceding, accompanying of following hyperthyroidism. Although ophthalmopathy has its clinical expression only in 50% of patients with Graves disease, the ultrasound exploration and the CT scan of the orbital area, as well as the values of intraocular pressure showed that occult changes exist in all patients. The etiopathological autoimmune mechanism responsible of ophthalmopathy doesn't imply the same autoantibodies, though ophthalmopathy is associated with thyrotoxicosis, and the degree of ocular changes is not related to the level of autoantibodies directed against the TSH receptors nor to the level of antibodies involved in thyroid cells' growth.

Leprechaunism: report of two cases and review.

Two new cases of leprechaunism are reported, one of which from consanguinous parents. Both cases show the clinical picture characteristic of this syndrome: severe pre- and postnatal growth failure, psychic backwardness, lack of adipose tissue, cutis laxa; elf-like face, large ears, globular eyes, hypertelorism, micrognathia and various degrees of external genitalia hypertrophy. Endocrinologically, one of the patients shows the syndrome of low T3.

Effect of short-term lithium carbonate administration in hyperthyroidism, with or without associated ophthalmopathy.

The study was carried out on 21 female hyperthyroid patients aged 22-53 years, with or without associated ophthalmopathy, admitted to the Endocrinology ward of the 1st Medical Clinic of the Craiova County Hospital, Romania, between 1983 and 1985. Administration of lithium carbonate was proceeded and followed by radioimmunoassay (RIA) determinations of T3 and T4 and measurement of Achilles' reflex (AR). Two regimens were employed.

Investigation of thermic transition and renaturation of high polymerized DNA extracted from thyroid nodule.

The study was carried out on 16 cases of mixed thyroid hypertrophy in which total or partial thyroidectomy was performed. Fragments collected intraoperatively from the thyroid nodule were used for extraction of high polymerized DNA. At the same time with quantitative evaluation of DNA, RNA and proteins were also assayed.

Histochemical and enzymatic study of the thyroid nodule.

Twenty-four cases of uninodular and polynodular thyreopathy subjected to partial or total thyroidectomy in 1980--1981 were studied. At the same time with the general morphological study, the activity of the following cellular enzymes in the thyroidian tissue were assayed: lactic dehydrogenase (LDH), glutamic oxalacetate transaminase (GOT), glutamic pyruvate transaminase (CPT) and creatine phosphokinase (CPK). Correlations between the morphophysiopathology of the thyroid nodule and its enzymatic activity have been made.
