Side-effects and complications of lithium therapy were examined by evaluation of data registered from 73 patients. Transitory subjective complaints would often occur during the initial phase of therapy, but they do not require any additional therapy. Occasional development of struma and sometimes high increase of body weight require regular controls of these values. Disposing factors concerning the possible occurrence of epileptic seizures and extra-pyramidal disorders under lithium therapy are Melipramin as well as organic cerebral lesions.

The studies included 64 children with newly diagnosed epilepsy, aged from 6 to 15 years of life. In 25 children with partial and secondary generalized seizures monotherapy with carbamazepine was introduced; in 19 children with primary generalized seizures--with phenobarbital, and in patients with both types of seizures--with primidone. Monotherapy was controlled by means of blood serum drug concentration level monitoring; the therapy was successful in all the children. The group did not include patients with mental retardation, and epilepsy was idiopathic. Prior to the institution of treatment, a single determination of blood serum triiodothyronine, thyroxine, TSH, prolactin, cortisol, LH and testosterone was made. Psychological test were carried out employing Wechsler's scale, Bender-Santucci test, rhythmic structures developed by Mira Stambak and test of manual dexterity (card display). In order to evaluate short-term effects of the employed drugs upon the blood serum concentration values of the studied hormones, a repeated determination was made one month after the initiation of therapy. The third determination was made one year after the onset of treatment in order to assess the long-term effects. The effect of drugs upon their cognitive functions was assessed in a follow-up psychological testing performed after one year of therapy. The studies combined with statistical analysis led to a conclusion that after one month of monotherapy there occurred a significant drop in thyroxine concentration levels, still augmented after one year. Patients treated with carbamazepine showed a significant decrease of T3 levels after one month and one year, whereas treatment with phenobarbital and primidone did not result in significant changes of T3 concentration. Yet, T3 and T4 concentration values did not exceed normal limits. No type of monotherapy resulted in significant long-term changes of TSH concentration levels. No clinical signs of hypothyroidism nor goiter were observed in the studied children. After one month of monotherapy with carbamazepine and phenobarbital there was observed a significant increase of prolactin and cortisol levels, which was absent after one year. The values observed did lie within normal limits. No significant changes were observed with respect to the effect of the studied drugs upon blood serum LH and testosterone levels. After a one-year monotherapy with primidone the children revealed a significant improvement of results measured on performance scale and by means of a full Wechsler scale. Carbamazepine and phenobarbital did not affect the intelligence quotient of the studied children.(ABSTRACT TRUNCATED AT 400 WORDS)

The association of juvenile diabetes mellitus (DM), diabetes insipidus (DI), optic atrophy (OA) and sensorineural deafness (D) is known as DIDMOAD or Wolfram syndrome. Aside from these four cardinal features, a wide variety of abnormalities of the nervous system, urinary tract and endocrine glands have been described in this syndrome. In this report, the clinical features of six patients with DIDMOAD syndrome are presented. All six patients had DM. Five of the six patients had DI, five OA and five displayed abnormal audiogram findings. In addition, two had goiter, two delayed puberty, one seizure and one mental retardation with depression attacks. Urinary tract dilatation was recorded in five patients. Four patients developed typical complications of DM. One of them had overt nephropathy and arthropathy despite the short duration of DM. In addition, this patient had diabetic retinopathy, which is considered to be rare in this syndrome.

We describe a euthyroid patient who presented with a goiter that continued to enlarge despite levothyroxine administration. Three fine-needle aspirations for cytology were nondiagnostic. An open biopsy was complicated by bleeding from the surgical site. Primary systemic amyloidosis was diagnosed on the basis of the goiter histology, bone marrow aspirate, and urine immunoelectrophoresis. The patient received melphalan and steroid treatment and survived for an additional 16 months. This period was complicated by congestive heart failure, generalized seizures, and upper gastrointestinal bleeding. Our case illustrates the difficulties in making the diagnosis and in treatment of primary systemic amyloidosis.

Resistance to thyroid hormone (RTH) is a syndrome in which patients have elevated thyroid hormone (TH) levels and decreased sensitivity to its action. We describe a child with extreme RTH and a severe phenotype. A 22-month-old female presented to the NIH with goiter, growth retardation, short stature, and deafness. Additionally, the patient had hypotonia, mental retardation, visual impairment, and a history of seizures. Brain magnetic resonance imaging showed evidence of demyelination and bilateral ventricular enlargement. The patient had markedly elevated free T3 and free T4 levels of more than 2000 pg/dl (normal, 230-420 pg/dl) and more than 64 pmol/liter (normal, 10.3-20.6 pmol/liter), respectively, and TSH of 6.88 mU/liter (normal, 0.6-6.3 mU/liter). These are the highest TH levels reported for a heterozygous RTH patient. A T3 stimulation test confirmed the diagnosis of RTH in the pituitary and peripheral tissues. Molecular analyses of the patient's genomic DNA by PCR identified a single base deletion in exon 10 of her TRbeta gene that resulted in a frameshift and early stop codon. This, in turn, encoded a truncated receptor that lacked the last 20 amino acids. Cotransfection studies showed that the mutant TR was transcriptionally inactive even in the presence of 10(-6) M T3 and had strong dominant negative activity over the wild-type receptor. It is likely that the severely defective TRbeta mutant contributed to the extreme RTH phenotype and resistance in our patient.

Tuberous sclerosis complex is hereditary multisystemic, neurocutaneous disorder characterized by hamartomatous lesions mainly involving the brain, skin and viscera. Thyroid gland is rarely affected in these patients. Case history of a patient with tuberous sclerosis complex and diffuse and binodular goiter was presented. No epileptic seizures occurred despite multiple intracranial calcifications, cortical and subependimal tubers, revealed by neuroimaging. Borderline intellectual functioning was determined. Ultrasonographic findings of the heart, abdomen and pelvis were normal. Bone radiographs revealed multiple cystic lesions of the metacarpal, metatarsal and terminal phalanges. Clinical, endocrine and metabolic evaluations were performed because of anxiety, mild weight loss, transient problems of swallowing and breathing complaints, developing when she was 39 years old. Palpable diffuse and asymmetric thyroid enlargement was found. Laboratory tests of thyroid function, ultrasonographic examination and scintiscanning of the thyroid gland and patohistological analysis of fine-needle aspiration biopsy revealed the euthyroid, inactive, diffuse and binodular goiter. Unusual association of goiter and tuberous sclerosis was discussed.

A 42-yr-old woman presented with hyperthyroidism and a large, firm, irregular goiter. Within a few weeks she became hypothyroid. Five months later she developed increasingly severe neck pain and compressive symptoms. The goiter had become rock hard. A fine needle aspiration biopsy showed features of chronic thyroiditis and fibrosis. She partially responded to a course of glucocorticoids. Tamoxifen was added, with marked improvement in goiter size and pain. Both medications were tapered off. Two months later the patient experienced paresthesias of the fingertips, perioral numbness, and a seizure. She was found to have spontaneous primary hypoparathyroidism. Three months later the patient became hoarse and experienced difficulty in breathing. She was found to have a massively enlarged thyroid with compression of the right internal jugular vein and encasement of the right carotid artery as well as tracheal narrowing. She also had right vocal cord paralysis due to recurrent laryngeal nerve involvement. Because of airway compromise, an emergency isthmusectomy was performed, and the patient was given a postoperative course of glucocorticoids with gradual improvement. Postoperative diagnosis was Riedel's thyroiditis. Two months later she presented with near-syncope and was found to have bradycardia, hypotension, and right Horner's syndrome, presumably due to compression of the right carotid sheath. She was given i.v. glucocorticoids and tamoxifen. Six months later and 18 months after her initial presentation, the patient is doing remarkably well. Her goiter has regressed by more than 50%, and she no longer has any pain or difficulty breathing. She remains a little hoarse and has persistent hypothyroidism and hypoparathyroidism. She is taking prednisone (5 mg, this is being tapered very slowly) and tamoxifen (20 mg) daily. This case illustrates the protean manifestations of Riedel's thyroiditis, a rare but fascinating disease. The epidemiology of this disease, its pathophysiology and complications, and the roles of surgery and medical therapy are reviewed.

The thyroid gland is a relatively uncommon site for a secondary malignancy; even less common is a case of malignant melanoma metastatic to the thyroid. We describe the case of a 68-year-old man who presented with a neck mass in the posterior triangle. Fine-needle aspiration biopsy (FNAB) identified the mass as a malignant melanoma. The patient had had no known primary skin melanoma. He underwent a left modified radical neck dissection, and the mass was discovered to be a positive lymph node. Postoperatively, he declined to undergo radio- and chemotherapy. Eighteen months later, he returned with a diffusely enlarged thyroid. FNAB again attributed the enlargement to malignant melanoma. Soon thereafter, the patient began experiencing seizures, and on magnetic resonance imaging, he was found to have metastatic disease to the brain. He developed ventilator-dependent respiratory failure and required a subtotal thyroidectomy for the placement of a tracheostomy tube. Patients who present with a thyroid nodule and who have a history of malignancy present a diagnostic dilemma: Is the nodule benign, a new primary, or a distant metastasis? The findings of this case and a review of the literature strengthen the argument that any patient with a thyroid mass and a history of malignancy should be considered to have a metastasis until proven otherwise.

There is currently little literature pertaining to levothyroxine overdose apart from minor or accidental overdoses in the pediatric population. In particular, there is little information available on how to confidently differentiate levothyroxine overdose from endogenous causes of thyrotoxicosis when there is no history available at the time of assessment. We report a levothyroxine (15,800 mcg) and citalopram (2,460 mg) overdose in a 55-year-old woman presenting with seizure and tachycardia in which the diagnosis was not initially suspected. Clinical data, including a long history of treated hypothyroidism and lack of a goiter; and biochemical findings, such as an incompletely suppressed thyroid-stimulating hormone (TSH) level, despite a markedly elevated free thyroxine level (FT4), a normal sex hormone-binding globulin level at baseline, and an undetectable thyroglobulin, supported the diagnosis of thyrotoxicosis due to a massive exogenous thyroid hormone overdose. Treatment was given to decrease free triiodothyronine (FT3) conversion and increase thyroid hormone clearance with dexamethasone and cholestyramine. The patient made a full recovery. Levothyroxine overdose can result in subtle symptoms and signs clinically, even when in massive quantities. This can make diagnosis challenging. Biochemical features, such as the pattern of thyroid hormone elevation and thyroglobulin levels, help differentiate exogenous thyroid hormone overdose from endogenous causes of thyrotoxicosis.

BACKGROUND Basal ganglia calcification (BGC) is a rare sporadic or hereditary central nervous system (CNS) abnormality, characterized by symmetric or asymmetric calcification of the basal ganglia. CASE REPORT We report the case of a 65-year-old Gypsy female who was admitted for a tetanic seizure, and who had a history of polyneuropathy, restless-leg syndrome, retinopathy, diabetes, hyperlipidemia, osteoporosis with consecutive hyperkyphosis, cervicalgia, lumbalgia, struma nodosa requiring thyroidectomy and consecutive hypothyroidism, adipositas, resection of a vocal chord polyp, arterial hypertension, coronary heart disease, atheromatosis of the aorta, peripheral artery disease, chronic obstructive pulmonary disease, steatosis hepatis, mild renal insufficiency, long-term hypocalcemia, hyperphosphatemia, impingement syndrome, spondylarthrosis of the lumbar spine, and hysterectomy. History and clinical presentation suggested a mitochondrial defect which also manifested as hypoparathyroidism or Fanconi syndrome resulting in BGC. After substitution of calcium, no further tetanic seizures occurred. CONCLUSIONS Patients with BGC should be investigated for a mitochondrial disorder. A mitochondrial disorder may also manifest as tetanic seizure.
