The serum alpha-1 acid glycoprotein of 9 euthyroid subjects, 14 hypothyroid patients and 21 hyperthyroid patients was determined by radial immunodiffussion in agar plates. The serum alpha1 acid glycoprotein level in both the hypothyroid and hyperthyroid patients were significantly lowered when compared to the euthyroid subjects. There was no significant correlation between the alpha-1 acid glycoprotein level mid the Liothyronine resin uptake (T3 resin. uptake) and the serum total Thyroxine Iodide (T4I) level.
Thyrotoxic psychosis is an uncommon phenomenon and the presentation is usually of the affective disorders. Three cases manifesting psychotic symptoms akin to schizophrenia are described. The neurobiocheinistry and treatment are discussed.
A total of 23 patients with psychoses associated with thyrotoxicosis were admitted to the psychiatric unit of a University Hospital over a 13-year period, of which 20 patients were included in this retrospective study. It was found that a parallel relationship between thyrotoxicosis and psychosis appears to exist in six patients, while in the remaining 14 patients, the course of the two disease processes were largely independent of each other. Paranoid delusions and auditory hallucinations were the most prominent psychiatric symptoms. Depression was commonly seen even in patients who were not having an affective illness. In four patients, a mixed schizo-affective psychosis was seen, suggesting that the diagnostic distinction between the affective and schizophrenic reactions are often blurred in psychosis associated with thyrotoxicosis.
This report deals with the problems of a young man who was clinically euthyroid but biochemically hyperthyroid. The possibility of peripheral resistance to thyroid hormones to explain this paradoxical state is discussed. The importance of recognising this condition to avoid the erroneous diagnosis of thyrotoxicosis and inappropriate therapy is stressed.
The third and final meeting of a coordinated research programme on the diagnosis and management of thyroid disorders was held in Vienna from 15 to 17 December 1986. The participants were from Czechoslovakia, Egypt, Israel, Malaysia and Thailand. Each participant had studied between 500 and 1000 patients for thyroid function evaluation by performing T3, T4 and TSH radioimmunoassays. Each had also used the newly available supersensitive immunoradiometric (IRMA) assay in a group of patients to compare the efficiency of the new assay with that of the conventional assay. A microcomputer was provided to each participant for data analysis. Internal quality control was studied by establishing precision profiles and external quality control was on the basis of pooled standard sera in different ranges. Recommendation for the strategy suggested T4 RIA as the test of first choice in each category of thyroid function. IRMA TSH was suggested as a second test in borderline cases.
We report a patient with unusual manifestations of hyperthyroidism which initially suggested lymphoma. The pathophysiology of these features in thyrotoxicosis is discussed. The need to consider thyrotoxicosis in an otherwise unexplained case of lymphoid hyperplasia will be stressed.
This report deals with a middle aged man in whom the presenting symptom of the disorder was dysphagia. The clinical approach to the final diagnosis of thyrotoxic myopathy causing dysphagia is outlined and the pathophysiology of dysphagia then discussed. The need to include thyrotoxicosis in the differential diagnosis of an otherwise unexplained case of dysphagia is stressed.
The presenting features of 236 thyrotoxic patients seen in the thyroid clinic were reviewed. 18.65% of these patterns had one or more dermatological complaints at presentation. There was no specific difference in this group of patients when compared with the general hyperthyroid population with regard to age, race, sex, duration of hyperthyroidism or biochemical indices of thyrotoxicosis. The two major complaints were itching and alopecia. The prevalence of pruritus at 6.4% in our series was identical to that of other workers, but we had a much lower occurrence of alopecia at 2.6%. The diagnosis of thyrotoxicosis was delayed in two patients in whom the only major complaint was pruritus. These symptoms cleared quickly when these patients became euthyroid. However there were other patients who noted hair loss with anti-thyroid medications. The incidence of vitiligo, eczema, onycholysis in our series was much lower those quoted in the Western literature The occurrence of pretibial myoxoedema in our series is similar to that of other workers from this region. The other miscellaneous manifestations include urticaria, xanthelasma and systemic lupus erythematosis. In conclusion we feel the cutaneous manifestations of hyperthyroidism are common in our patients.
Twenty eight patients with hyperthyroidism complicating their pregnancies were seen at the Obstetrics and Gynaecology Department, University Hospital, Kuala Lumpur, Malaysia in a six-year period. All patients were treated with antithyroid drugs, carbimazole being the mainstay of treatment. The incidence of the disease was 0.9 per 1000 births and was similar with other series. No cases of fetal goitre were noted. The mean birth weight was 2952 g; there was no significant difference in the birth weight of term live births in patients treated with carbimazole alone or carbimazole combined with propranolol.
A 25 year old female presented with hypothyroidism which was followed by the development of hyperthyroidism about 1 1/2 years later. This uncommon phenomenon is postulated to result from changes in the relative amounts of stimulatory and inhibitory TSH receptor antibodies. This case illustrates the possible continuum between Graves' disease and Hashimoto's thyroiditis within the broad spectrum of autoimmune thyroid disease.

A 32 year old male thyrotoxic presenting with gynaecomastia, galactorrhoea and later complicated with hypokalaemic periodic paralysis is presented. The gynaecomastia and galactorrhoea resolved with treatment. To the best of the author's knowledge this combination of association in one patient has not been reported previously.
Antithyroid drugs, radioiodine and surgery are lhe three modalities of treatment for Graves' hyperthyroidism. The treatment strategy depends on a clear understanding of the relative advantages and disadvantages of each mode of treatment as well as the individual patient's preference. Recent studies favour the use of high dose antithyroid drugs with thyroxine supplementation to induce a higher rate of remission. Radioiodine is likely to be favoured as the definitive form of treatment. Surgery still has a place particularly for young female patients with large goitres.
