Anorexia, constipation, vomiting and somnolence in a 39-year-old woman were at first misinterpreted as being of psychological and autonomic nervous system origin. Further clinical and biochemical tests revealed hyperthyroidism associated with hypercalcaemia and hypercalciuria. Thyrostatic treatment for 12 days caused regression of the hypercalcaemia and, after subtotal resection, serum calcium levels and urinary calcium excretion returned to normal for good. The hypercalcaemia syndrome must therefore be assumed to have been the direct result of the hyperthyroidism.

The historical and clinical features and the haematological and biochemical changes in 126 cats with hyperthyroidism are described; 125 of the cats were domestic short- or longhaired, and one was a chinchilla. There were 62 males and 64 females with a mean age of 13.0 years. The duration of signs ranged from two days to two years with a mean of 5.4 months. The historical and clinical features were weight loss, polyphagia, polyuria/polydipsia, tachycardia, hyperactivity, diarrhoea, respiratory abnormalities, other cardiac abnormalities, skin lesions, vomiting, moderately raised temperature, decreased activity, decreased appetite, congestive cardiac failure, haematuria and intermittently decreased appetite. Goitre was palpable in 123 cats. The serum total thyroxine concentrations of the cats were more than three standard deviations above the mean of the reference range. Serum total tri-iodothyronine concentrations ranged from 0.78 to 14.96 nmol/litre and were within the reference range in 11 of the cats. Mild hyperthyroidism was a much commoner cause of high normal or marginally above normal thyroid hormone concentrations than severe, concurrent, non-thyroidal illness. Other common biochemical changes were increased of serum alanine aminotransferase, urea, aspartate aminotransferase, alkaline phosphatase and lactate dehydrogenase. There were minimal changes in the red cell parameters. Leucocyte changes showed two trends: a mature neutrophilia, either with or without an accompanying leucocytosis often in association with a lymphopenia, or an eosinophilia, either with or without a lymphocytosis.

Biochemical evidence of hyperthyroidism is frequently encountered in hyperemesis gravidarum, but its relationship to the cause of hyperemesis is unknown. We studied the relationship of serum hCG, thyroid function, and severity of vomiting among 57 hyperemesis patients and 57 controls matched for gestational age. TSH was suppressed in 60% of hyperemesis patients and 9% of controls. hCG correlated directly with free T4(r = 0.45, P < 0.001) and inversely with TSH (r = -0.48, P < 0.001). Hyperemesis patients had significantly greater mean serum hCG, free T4, total T3, and estradiol, and lesser serum TSH compared to controls. Hyperemesis patients with suppressed TSH had significantly greater free T4 and hCG compared to those with TSH in the normal range. Control and hyperemesis subjects were divided into four groups based on the severity of vomiting. The degree of biochemical hyperthyroidism and hCG concentration varied directly with the severity of vomiting. Unextracted serum was tested for thyrotropic activity by measuring its effect on iodide uptake in cultured FRTL-5 rat thyroid cells. Thyrotropic activity correlated with serum hCG (r = 0.50, P < 0.001). These data show that biochemical hyperthyroidism is a common finding in patients with hyperemesis gravidarum and suggest that hCG is the thyroid stimulator in this state. The increased estradiol concentration in patients with hyperemesis gravidarum may be attributed to the effects of hCG on steroidogenesis.

Thyroid function was evaluated in 41 consecutive women with hyperemesis gravidarum (HG). In 11, increased free thyroxin concentrations (FT4) were measured. After one week of conservative therapy, 4 patients with persistent emesis were treated with antithyroid agents. Three of these 4 displayed other signs of hyperthyroidism. Emesis resolved in the other 7 patients within a week of conservative therapy. FT4 levels also returned to normal in these 7 patients within several weeks. Thyrotropin-releasing hormone (TRH) was administered to 10 of the 11 patients. Abnormal TSH responses, suggesting varying degrees of autonomous thyroid function were noted in all 4 patients treated with antithyroid drugs and in 3 of the untreated patients. Underlying clinical signs and symptoms of hyperthyroidism should be sought in patients with HG. In the presence of persistent emesis, despite conservative therapy of at least one week's duration and the presence of abnormal thyroid function studies, the use of antithyroid agents should be considered.

A male patient with hyperemesis as a result of hyperthyroidism was presented. Investigations for causes were negative except for hyperthyroxinaemia. Treatment with antithyroid drug relieved the symptom. Hyperemesis associated with hyperthyroidism occurs predominantly in females. A likely emetic factor oestrogen. Hyperthyroidism could have potentiated this effect. Levels of oestrogens are raised in thyrotoxicosis. The hyperthyroidism, the raised oestrogens and a low emetic threshold conspired to hyperemesis in this patient, a situation not unlike hyperemesis gravidarum. Thyrotoxic vomiting once recognised is readily by antithyroid treatment.

A Down's syndrome patient was hospitalized for evaluation of vomiting, abdominal pain, and a history of weight loss. A subsequent workup revealed that she had hyperthyroidism. The treatment of choice was radioactive iodine therapy. The patient had a history of consistent nausea and incontinence for urine and feces. Special problems posed by the patient and radiation safety are discussed.

The efficacy and safety of the antithyroid drug methimazole were evaluated over a 3-year period in 262 cats with hyperthyroidism. In 181 of the cats, methimazole was administered for 7 to 130 days (mean, 27.7 days) as a preoperative preparation for thyroidectomy. The remaining 81 cats were given methimazole for 30 to 1,000 days (mean, 228 days) as sole treatment for the hyperthyroid state. After 2 to 3 weeks of methimazole therapy (10 to 15 mg/d), the mean serum thyroxine (T4) concentration decreased significantly (P less than 0.001) from a pretreatment value of 12.1 micrograms/dl to 2.1 micrograms/dl. The final maintenance dose needed to maintain euthyroidism in the 81 cats that were given methimazole as sole treatment for hyperthyroidism ranged from 2.5 to 20 mg/d (mean, 11.9 mg/d). Clinical side effects developed in 48 (18.3%) cats (usually within the first month of therapy), which included anorexia, vomiting, lethargy, self-induced excoriation of the face and neck, bleeding diathesis, and icterus caused by hepatopathy. Mild hematologic abnormalities developed in 43 (16.4%) cats (usually within the first 2 months of treatment), which included eosinophilia, lymphocytosis, and slight leukopenia. In ten (3.8%) cats, more serious hematologic reactions developed including agranulocytosis and thrombocytopenia (associated with bleeding). These hematologic abnormalities resolved within 1 week after cessation of methimazole treatment. Immunologic abnormalities associated with methimazole treatment included the development of antinuclear antibodies in 52 of 238 (21.8%) cats tested and red cell autoantibodies (as evidenced by positive direct antiglobulin tests) in three of 160 (1.9%) cats tested.(ABSTRACT TRUNCATED AT 250 WORDS)

Since the approval of lithium use in treatment of acute mania, there have been numerous clinical trials of lithium in medical and psychiatric disorders. This paper gives a brief review of the literature on lithium trials in approximately fourteen medical conditions. These are: hyperthyroidism, metabolizing thyroid cancer, syndrome of inappropriate secretion of antidiuretic hormone, premenstrual tension syndrome, anorexia nervosa, Felty's syndrome, chemotherapy-induced neutropenia, aplastic anemia, seborrheic dermatitis, eczematoid dermatitis, cyclic vomiting, diabetes mellitus and asthma. Most of the case reports cited showed the efficacy of the side effects from lithium salt in the management of the symptoms and signs of these disorders, however, well-designed and controlled studies give negative results. The positive results are reported in the group of disorders having an underlying subdromal affective syndrome such as premenstrual tension syndrome and anorexia nervosa. Other encouraging reports include the effect of lithium to induce leucocytosis in Felty's syndrome and chemotherapy-induced neutropenia.

Apathetic thyrotoxicosis is frequently difficult to recognize and can imitate a variety of diseases. A patient with a severe thyrotoxic state is reported, who presented with protracted epigastric pain and vomiting. Hyperthyroidism should be considered in patients with such prolonged and unexplained symptoms.

Vomiting is a poorly recognized manifestation of hyperthyroidism. During pregnancy, this appearance can be indistinguishable from hyperemesis gravidarum. Two patients with intractable hyperemesis gravidarum were found to have hyperthyroidism. Their symptoms resolved when thyroid functions returned to normal. Given the ease of laboratory confirmation, excellent therapy, and the seriousness of delay in diagnosis, thyrotoxicosis should be considered in patients with unusual or severe hyperemesis gravidarum.
