Abstract
Retrospective analysis of 11 Chinese patients with Graves' thyrotoxicosis developing agranulocytosis during anti-thyroid treatment was done. Seven of them received methimazole and 4 received carbimazole. None of the 11 patients had taken propylthiouracil. The major chief complaints were high fever (100%), chillness (91%), and sore throat (73%). The duration of drug treatment prior to the detection of agranulocytosis ranged from 13 to 63 days (mean +/- 1SE: 33.1 +/- 16.1). At the time of agranulocytosis detected, the peripheral leukocyte counts were 0.5 to 2.1 X 1000/mm3 (mean +/- 1SE: 1.05 +/- 0.47 X 1000/mm3), absolute neutrophil counts 0 to 450/mm3 (mean +/- 1SE: 54.27 +/- 132.12/mm3), and hemoglobin 8.2 to 15.9 g/dl (mean +/- 1SE: 11.85 +/- 2.24 gm/dl). Three of the 11 patients had positive bacterial blood cultures. The recovery time of absolute neutrophil counts above 500/mm3 ranged from 3 to 25 days (mean +/- 1SE: 10.5 +/- 6.6) after discontinuation of antithyroid drugs. Mortality was found in 2 of them (18%).

Abstract
A 56-year-old man presented with clinical and biochemical hyperthyroidism with high thyroid 99mTc uptake, positive result for antimicrosomal antibody (MCHA; 1:8,100) and markedly high activities of thyrotropin-binding inhibitory immunoglobulin (TBII; 90.0%) and thyroid-stimulating antibody (TSAb; 2,400%). Fifty days after the initiation of antithyroid drug therapy, he developed a painful tender enlarged thyroid and an accelerated erythrocyte sedimentation rate (ESR), which were followed immediately by hypothyroidism with a transient increase in MCHA titer (peak; 1:218,700) despite of maintenance of high TBII and TSAb activities. Two and a half months after the recovery from hypothyroidism, recurrent hyperfunction was observed with further elevation of TSAb activity (4,643%). After about 2 weeks, recurrences of a painful tender enlarged thyroid and an accelerated ESR, which were followed by abrupt progression to hypothyroidism, were found. Specimens obtained when he had still slightly tender goiter after the first and second episodes of neck pain showed microscopically extremely extended interstitial fibrosis with collapsed follicles and moderate lymphocytic infiltration. Thyroid-stimulation-blocking antibody was not detected at either onset of hypothyroidism. Thus, it is possible that Graves' disease, subacute aggravation of chronic thyroiditis and hypothyroidism coexist in the same individual. In such patients, thyroid status may be determined by the degree of each of the stimulating factors (TSH, TSAb and/or unknown factors) and suppressive or destructive factors (humoral and/or cellular) and may be changed in a very short interval.

Abstract
Insulin autoimmune syndrome is a syndrome consisting of fasting hypoglycemia, hyperinsulinemia and detectable insulin-binding antibodies in patients who have never been exposed to exogenous insulin. Four cases who developed symptoms of hypoglycemic attack with self-limited duration and spontaneous remission were collected in our hospital from 1984 to 1988. The elevated serum total and free insulin and C-peptide levels, as well as the titer of insulin autoantibodies, decreased gradually; but insulin autoantibodies were still present in the serum for more than six months after the initial episodes of hypoglycemia. Three of four patients had Graves' disease and developed the syndrome after methimazole treatment. The fourth one had a history of hemorrhagic cystitis and denied history of specific drug exposure. The cause or stimulus for insulin autoantibody formation is still unknown, but drugs containing a sulfhydryl group like methimazole may play a role in the development of the syndrome. Extremely high insulin antibodies in patients with fasting hypoglycemia along with elevated serum levels of insulin and C-peptide suggest a diagnosis of insulin autoimmune syndrome and usually exclude the possibility of insulinoma or factitious hypoglycemia.

Abstract
A literature review of individual pregnancies and recent surveys involving large cohorts reveal an association between congenital malformation and maternal hyperthyroidism, suggesting that some aspect of hyperthyroidism or its treatment might compromise the development of the fetus. Experiments have shown that the thyroid antagonist, ethylenethiourea (ETU), causes fetal malformations when administered to pregnant rats, but it is not known whether it is ETU or the imbalance in maternal thyroid hormone which it causes which is the teratogenic agent. Here we employ in vitro culture to determine the possible direct effects on rat embryos of two thyroid antagonists, ETU and methimazole (MMI), the latter being one which is used for treatment of thyrotoxicosis in humans. It was found that ETU can compromise the development of rat embryos in vitro, confirming that ETU has a direct effect on the rat embryo. It was also found that MMI can cause abnormal development of rat embryos in vitro, although the concentration at which MMI disturbs rat embryogenesis is higher than that which is reached in hyperthyroid patients treated with clinical doses of MMI or carbimazole.

Abstract
Three patients with Graves' disease who spontaneously developed hypothyroidism after treatment with antithyroid drugs are described herein. Patient 1 developed a painful tender thyroid enlargement with a fever and accelerated erythrocyte sedimentation rate when she was receiving maintenance therapy with methimazole, and she progressed to persistent hypothyroidism with increased titers of antithyroglobulin and antimicrosomal antibodies and marked reduction of goiter size within the subsequent 2 months. Thyroid-stimulating hormone-binding inhibitory immunoglobulins (TBIIs) and thyroid stimulation-blocking antibody (TSBAb) were absent when she was hypothyroid. Hypothyroidism probably resulted from autoimmune thyroid destruction due to subacute aggravation of Hashimoto's thyroiditis. During the clinical course of patient 2, accelerated erythrocyte sedimentation rate and later transient increases of antimicrosomal and antithyroglobulin antibody titers were observed repeatedly (four times), and she finally fell into overt hypothyroidism. She also had negative results of tests for TBII and TSBAb. Her hypothyroidism appeared to result from repeated thyroid destruction due to aggravation of Hashimoto's thyroiditis. Patient 3 fell into hypothyroidism when receiving a small dosage of methimazole. The TBII and TSBAb were strongly active when she developed hypothyroidism, which thus seemed to be due to blocking antibody. Patients with Graves' hyperthyroidism may eventually progress to hypothyroidism later by several different mechanisms. Severe and sudden or slowly repeated thyroid destruction due to aggravation of Hashimoto's thyroiditis is one mechanism. Another may be the appearance of a blocking antibody to the TSH receptor.

Abstract
A very rare case of granulomatous hepatitis in a 56-year old woman with hyperthyroidism, under long-term treatment with methimazole, is reported. Liver biopsy showed multiple non caseous granulomas in the portal triads, consisted of epithelioid and multinucleated cells, lymphocytes and isolated eosinophils. The presence of eosinophils in granulomas, could indicate an iatrogenic aethiology.

Abstract
This study was aimed at establishing the importance of routine monitoring of white blood cell counts in patients with Graves' disease receiving antithyroid drug treatment. In the 12-year period from 1975 to 1987, 15,398 patients with Graves' disease receiving treatment with antithyroid drugs were seen at our clinic. Of these, 55 (0.4%) were found to have agranulocytosis. Agranulocytosis was defined as a granulocyte count of 0.5 x 10(9)/L or less. In only 12 of the 55 patients was agranulocytosis detected after the occurrence of infection (symptomatic; classic agranulocytosis). The remaining 43 patients were asymptomatic when agranulocytosis was detected during routine white blood cell count monitoring. However, 14 of these 43 patients became symptomatic several days after withdrawal of antithyroid drug treatment despite antimicrobial treatment (asymptomatic to symptomatic). Twenty-nine patients who were treated appropriately had no symptom of infection throughout the course of the disease, despite the absence of or an extremely small number of granulocytes in circulation (asymptomatic). These results suggest that a "routine monitoring" of the white blood cell count could be the most effective way of predicting and detecting agranulocytosis due to antithyroid drug treatment.

Abstract
We report a case of methimazole-induced acute hepatic failure, which occurred 17 weeks after initiation of the drug in a 43-year-old man with hyperthyroidism and hepatitis B surface antigenemia. Postmortem needle autopsy of the liver revealed an established micronodular cirrhosis secondary to hepatitis B with moderate septal/portal inflammation, marked cholestasis and scattered acidophilic bodies. The serum hepatitis B surface antigen (HBsAg) was positive, but reactivation of hepatitis B was unlikely in view of the absence of a serum hepatitis B e antigen (HBeAg) and hepatitis B virus deoxyribonucleic acid (HBV-DNA) and negative stain for HBsAg and hepatitis B core antigen (HBcAg) in the liver tissue.

Abstract
We reviewed the records of approximately 7000 Japanese patients whose hyperthyroidism was treated with methimazole (MMI) alone. Four patients (Group I) developed agranulocytosis during a second course of MMI therapy and eight patients (Group II) during an initial course. Six patients (three in each group) received less than 30 mg MMI daily. Agranulocytosis occurred after more than 2 months of therapy (12 weeks-1 year) in five patients. Seven patients were less than 40 years of age. One patient displayed a gradual protracted development of agranulocytosis. These results indicate that agranulocytosis after MMI may occur irrespective of dose, age, duration of treatment, and with a second exposure.

Abstract
Two cases of propylthiouracil-associated acute hepatitis, one case of fatal methimazole-associated hepatocellular necrosis and one case of propylthiouracil-associated lupus-like syndrome are described. The literature related to antithyroid drug side effects and the mechanisms for their occurrence are reviewed and the efficacy and complications of thyroidectomy and radioiodine compared to those of antithyroid drugs. It is concluded that in most circumstances 131I is the therapy of choice for hyperthyroidism.

Abstract
The authors studied 389 Graves' hyperthyroid patients receiving either high propylthiouracil (PTU) or methimazole (MMI) daily doses or low doses to evaluate whether adverse effects were related to the thionamide drugs or its daily dose regimen. Group 1 patients (n = 286) received high PTU (728 +/- 216 mg/day, n = 92) or MMI (60 +/- 19 mg/day, n = 94) doses, and group 2 patients (n = 103) were treated with low PTU (255 +/- 85 mg/day, n = 39) or MMI (23 +/- 10 mg/day, n = 64) doses. Major adverse effects were observed in 11 (2.8%) patients. Of these, four (1.0%) had agranulocytosis, two (0.5%) were granulocytopenic and five (1.3%) had hepatotoxicity. Agranulocytosis occurred in two patients from each group, 0.7% and 1.9%, respectively from group 1 and group 2. There was no significant difference between the groups or the types of thionamide. There also was no correlation with the patients' age. All of the patients were hyperthyroid, and its onset occurred in the first to third month of treatment. Full recovery was achieved in all cases after drug withdrawal. Four of 5 patients with hepatotoxicity were treated with high PTU doses, and one patient received low MMI doses (p less than .05). All patients were euthyroid. Arthralgias, skin rash and gastric intolerance, the minor adverse effects of thionamides studied, were observed in 52 (13.4%) of the patients. Although no significant differences were found, most of the patients experiencing side effects were from group 1 an received MMI therapy. These adverse effects did not demand drug withdrawal.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Serum thyroid hormone and TSH concentrations were monitored in a patient with multinodular endemic goiter and severe methimazole (MMI) induced hypothyrodism up to 190 days after drug withdrawal. Serum concentrations of TT3, TT4 and TSH returned to normal values at the 6th., the 140th, and the 120th. day respectively. Within the first 20 days after MMI withdrawal the increase of serum T3 levels was correlated with the observed decrease of serum TSH concentrations. Successively T3 values decreased and T4 levels progressively increased. Six months after MMI withdrawal basal serum TSH concentration was normal while an exaggerated response to TRH was observed. We think that this peculiar hormone pattern is due to iodine depletion. In this case TSH hyperstimulation increases predominantly T3 secretion demonstrating the reduced thyroidal ability to produce T4 when hyperstimulated.

Abstract
Side effects of antithyroid treatment were retrospectively analysed in 1256 patients with hyperthyroidism. Overall rate of side effects was 14.3%. Skin reactions were the most frequent ones (5.6%), followed by arthropathies (1.6%). The incidence of agranulocytosis was 0.14%. Median duration of all side effects was 1.5 months. In half the cases the side effects were controllable so that treatment was continued, although at a changed dosage. The rate of cross-reaction between carbimazole and thiamazole, on the one hand, and propylthiouracil, on the other, was 13.8% and 15.2%, respectively. The side effects became apparent after a mean of one month's treatment, almost always (in 97.1%) within the first year of treatment. There was a significant dose dependence for an initial thiamazole dose of over 20 mg (relative side effect risk of 2.3), and for an initial dose of over 30 mg for carbimazole (relative side effect risk of 1.6). Although most side effects were not dangerous, in normal instances the lowest possible dosage should be administered to control hyperthyroid metabolism. Long-term treatment with low doses seem to be without problems.

Abstract
A 47-year-old man with Graves' disease suffered from a feeling of hunger and sweating in the night, polyarthralgia and fever one month after the start of treatment with methimazole. The above symptoms were ascribed to the side effects of methimazole; insulin autoimmune syndrome and lupus-like syndrome. The change in the antithyroid drug to propylthiouracil caused an amelioration of the symptoms. In addition to an anti-insulin antibody with a high binding capacity, hyperglucagonemia (260 pg/ml with a plasma glucose level of 61 mg/dl) was observed, which returned to normal in parallel with the decrease in the insulin binding capacity of the plasma one month after beginning the treatment with propylthiouracil. A normal decrease in the plasma glucagon level due to exogenous insulin (2 mU/kg/min) was observed with the euglycemic clamp. However, the plasma glucagon level was not suppressed by the oral glucose loading and elicited a poor response to the arginine infusion. Taking previous reports into account, this basal hyperglucagonemia seems to be a characteristic finding in the insulin autoimmune syndrome, while a sluggish response of glucagon to oral glucose or arginine infusion might be ascribed to hyperthyroidism. This is the first case report concerning a kinetical study of the glucagon secretion in insulin autoimmune syndrome with Graves' disease.

Abstract
The pregnancy of a women with diabetes mellitus was complicated by Graves' disease and maternal allergies to propylthiouracil and methimazole. Preparations for surgical removal of the thyroid gland were being made until pregnancy intervened. Several well-documented mechanisms of hyperthyroidism, including increased intestinal absorption of glucose, decreased insulin responsiveness, and increased glucose production may exacerbate glucose intolerance; the daily insulin requirement of this patient rose 80% from her pregestational dosage. When large doses of propranolol failed to control her thyrotoxic symptoms and led to severe, recurrent hypoglycemic episodes, subtotal thyroidectomy was performed. A 42% decrease in insulin requirements was observed postoperatively, with return to the euthyroid state. A propensity for symptomatic postoperative hypoglycemia should be anticipated in diabetic patients undergoing thyroidectomy.

Abstract
A prospective randomized trial with the conventional divided doses (10 mg 3 times daily, N = 29) and a small single daily dose (15 mg once daily, N = 25) of methimazole for the treatment of Graves' hyperthyroidism was performed. Within 8 weeks, almost 80% of the patients in both groups became euthyroid. The mean time required to achieve the euthyroid state was 6.0 +/- 2.8 and 6.0 +/- 3.8 weeks, respectively. TSH binding inhibitor immunoglobulin was found in about 90% of the patients in both groups before methimazole treatment. However, a gradual fall of its levels was observed in nearly all patients after treatment. There was no difference in the mean levels of TSH binding inhibitor immunoglobulin between the two groups during therapy. We conclude that the single daily dose regimen of 15 mg of methimazole will control Graves' hyperthyroidism in most patients, and TSH binding inhibitor immunoglobulin levels decrease in this regimen in the same way as with the conventional divided dose regimen (10 mg 3 times daily).

Abstract
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)

Abstract
A case of aplasia cutis after exposure to methimazole (Tapazole) in early pregnancy is described. Elevated maternal serum alpha-fetoprotein (MSAFP) and amniotic fluid alpha-fetoprotein (AFP) were found. Elevated MSAFP and amniotic fluid AFP in women exposed to methimazole may suggest this rare fetal condition.

Abstract
This paper reports a case of agranulocytosis that developed in a patient with hyperthyroidism two months after the administration of methimazole. The patient manifested symptoms of fever, sore throat, profound leukopenia, and oral complications such as generalized gingival necrosis and mucosa ulceration, which subsequently abated upon withdrawal of the drug. Dental practitioners should be aware of the potential of agranulocytosis associated with methimazole therapy. The oral manifestations should be kept in mind.

Abstract
The mechanism for agranulocytosis induced by antithyroid drugs is not established. The few available studies have proposed an immune-mediated process against mature granulocytes. We investigated the effect of methimazole and propylthiouracil and serum from a patient with methimazole-induced agranulocytosis on marrow myeloid colony growth. In the presence of normal serum or patient's recovery serum, antithyroid drugs had no effect on the growth of CFU-GM colonies from normal or patient's marrow. However, the patient's serum obtained during agranulocytosis inhibited the in vitro myeloid colony growth from both autologous and allogeneic bone marrow. These results are compatible with an immune-mediated mechanism for methimazole-induced agranulocytosis rather than a direct toxic effect of the drug on abnormally sensitive cells.

Abstract
This study was undertaken to determine the effect of methimazole on the pharmacokinetics of iv prednisolone in patients with Graves' disease. Twenty women were studied, including eight with severe infiltrative ophthalmopathy who had taken methimazole and T4 for at least 4 months, six with severe infiltrative ophthalmopathy who had undergone subtotal thyroidectomy and, therefore, required no antithyroid treatment, and six age-matched normal women. All were euthyroid. Each women received 0.54 mg/kg prednisolone as an iv bolus dose. Plasma total and unbound prednisolone concentrations were measured at multiple times during a 10-h study period by high pressure liquid chromatography and equilibrium dialysis. The clearance of both total and unbound prednisolone was increased significantly in the women receiving methimazole therapy compared to values in both control groups. The volume of distribution at steady state was similar in all groups. These results suggest that patients receiving methimazole have enhanced prednisolone metabolism and, therefore, they may require higher prednisolone doses.

Abstract
An infant girl with choanal atresia, athelia, minor anomalies, and mild to moderate mental retardation was born to a woman treated for hyperthyroidism throughout pregnancy with methimazole and propranolol. The patient's defects may be due to methimazole teratogenicity or could represent a previously undescribed syndrome affecting ectodermal structures.

Abstract
We have experienced two cases (Case 1: 21-year-old female, Case 2: 26-year-old female) of systemic lupus erythematosus (SLE) associated with hyperthyroidism. Case 1 had been treated with methimazole (MMI) and betamethasone for approximately two years. Although thyroid function improved with the treatment, laboratory data of SLE deteriorated. She was successfully treated with betamethasone alone. Case 2, who had severe side effect (severe hemorrhage due to gastric ulcer) during prednisolone treatment for SLE, was found to have an additional hyperthyroidism. She was treated with intermittent prednisolone administration alone. Physical findings as well as laboratory data of both SLE and hyperthyroidism improved by the therapy.

Abstract
Propylthiouracil and methimazole are frequently used in the management of hyperthyroidism. Two patients in whom adverse immunologic effects other than isolated agranulocytosis developed during treatment with propylthiouracil are described. A review of the literature revealed 53 similar cases over a 35-year period. Rash, fever, arthralgias and granulocytopenia were the most common manifestations. Vasculitis, particularly with cutaneous manifestations, occurs and may be fatal. The clinical evidence suggests that an immunologic mechanism is involved. A number of different autoantibodies were reported, but antinuclear antibodies were infrequent, and none of the cases met the criteria for a diagnosis of systemic lupus erythematosus. Thus, the reactions do not represent a true drug-induced lupus syndrome. Current hypotheses and experimental data regarding the cause of the reactions are reviewed. No specific clinical subgroup at high risk can be identified, and manifestations may occur at any dosage and at any time during therapy. Cross-reactivity between the two antithyroid drugs can be expected. Except for minor symptoms (e.g., mild arthralgias or transient rash), such reactions are an indication for withdrawal of the drug and the use of alternative methods to control the hyperthyroidism. In rare cases of severe vasculitis a short course of high-dose glucocorticoid therapy may be helpful.

Abstract
Insulin autoimmune syndrome is characterized by spontaneous hypoglycemia, glucose intolerance, hyperinsulinemia and insulin-binding antibodies in serum without previous immunization. A 31-year-old man with Graves' disease developed insulin autoantibodies after therapy with methimazole. The patient was unique in that persistent hyperglycemia with polyuria and polydipsia had continued for several days before frequent hypoglycemic attacks appeared. We were able to extract a huge amount of immunoreactive insulin (116,000 microU/ml) with acid-ethanol from his serum obtained in the diabetic stage, and serum C-peptide immunoreactivity was as high as 268 ng/ml. The insulin-binding activity of his serum was quite potent, and when 1:5,000 diluted serum was incubated with 125I-porcine insulin, 71.2% of the label could be precipitated by polyethylene glycol. The insulin-binding protein was identified as mainly IgG with kappa light chains. Insulin-binding activity was not detected in serum obtained before methimazole therapy, suggesting that the drug was responsible for the induction of antibodies in this patient. The antibodies recognized porcine, sheep, bovine and horse insulins as well as human insulin. The mechanisms by which the antibodies produced hyper- and hypoglycemia have also been discussed.

Abstract
The authors report a further case of methimazole-associated liver damage and present a brief review of eleven previous cases found in the literature. The main clinical features of this 58-year-old female patient were laboratory evidence of leucopenia and cholestasis, and biopsy features of fatty liver parenchyma degeneration with granulocytic portal infiltration and bile stasis, demonstrated 20 days after the initiation of antithyroid therapy with 20 mg methimazole daily. An immediate cholestatic liver reaction was also provoked by drug rechallenge, with spontaneous amelioration of signs and symptoms after drug discontinuation.

Aplasia cutis congenita, the localized absence of skin at birth, usually is an isolated scalp defect. We examined an infant with aplasia cutis congenita associated with maternal Grave's disease and the use of methimazole during pregnancy. This association was reported twice before. It has certain implications with respect to therapy of pregnant hyperthyroid women.

Abstract
The analgesic effect and the tolerability of alpha-methyl-4-(2-thienyl-carbonyl)phenylacetic acid (suprofen, Suprol) syrup 200 mg and metamizole syrup 500 mg were compared in a randomized single-blind study including hospitalized patients with severe to moderate chronic pain. The 2 treatment groups consisted of 30 subjects each and were homogeneous as to the demographic data. Pain intensity was appreciated by the investigator prior to the treatment and on days 2, 3, and 5 of the study; pain relief was assessed on days 2, 3, and 5 of the therapy. Although pain intensity was on treatment with suprofen more markedly reduced than with metamizole, there was no statistically significant difference between the 2 treatment groups (chi 2-test). The Mann-Whitney test revealed that on days 3 and 5 pain relief with suprofen was significantly superior to that with metamizole. According to the investigator's final global evaluation, suprofen syrup 200 mg had very good to good effect in 70% of the cases, whereas the effectiveness of metamizole was rated good to very good in 44%. Side-effects manifesting themselves as gastric irritation and nausea were recorded for 3 patients on suprofen and 2 subjects on metamizole.

Abstract
The duration of action of methimazole (MMI) was studied in patients with hyperthyroidism due to Graves' disease. Perchlorate discharge tests performed 24 h after MMI administration revealed greater than 10% discharge in 77% of 53 patients who received a single dose of 15 mg MMI and in 74% of 23 patients who received 30 mg. The mean percent discharges were 41.5 +/- 26.4% (+/- SD) and 35.4 +/- 28.0, respectively. Based on these results, hyperthyroidism was treated with a single daily dose (SDD) of 15 mg in 43 patients and with 30 mg in 32 patients, and the results were compared with retrospective analysis of 50 patients who were treated with divided doses of MMI (10 mg, 3 times daily). Within 12 weeks, 93% of the patients treated with 15 mg SDD, 91% treated with 30 mg SDD, and 86% treated with divided doses were euthyroid. The mean times to achieve euthyroidism in these patients were 5.3 +/- 3.6 (+/- SD), 5.3 +/- 3.1, and 5.6 +/- 3.0 weeks, respectively. Side-effects occurred in 2 patients treated with 15 mg SDD and in 6 treated with 30 mg SDD. We conclude that a single daily dose of 15 mg MMI is not only effective in most patients with Graves' hyperthyroidism, but also less frequently causes adverse effects.

Abstract
Anti-thyroid drugs are widely used to treat diffuse toxic goiter (Graves' disease). Of the two drugs currently available in the United States, propylthiouracil is prescribed far more often than is methimazole (Tapazole). However, compared with propylthiouracil, methimazole can be given as a single daily dose, is cheaper, and, at low doses, is associated with less major toxicity; for these reasons, methimazole should be used for the routine management of Graves' disease when anti-thyroid drugs are selected as primary therapy. On the other hand, because of certain pharmacologic factors, propylthiouracil should be used in selected situations, particularly in patients with "thyroid storm" and in pregnant or lactating women.

Abstract
In a single-blind study, 60 children in two age groups (30 patients: 6 months to 3 years; 30 patients: 3 years to 12 years), were orally treated with either alpha-methyl-4-(2-thienyl-carbonyl)phenylacetic acid (suprofen, Suprol), syrup 10 mg/ml or metamizole drops 50% for a maximum period of 4 days, up to 4 times a day. The children presented with high fever due to bacterial or virus infections. Body temperature, pulse rate, and respiratory rate were evaluated at the beginning and then 30 min, 1, 1 1/2, 2, 3, 4, 5, and 6 h after the first administration of the respective drug. Significant differences between the drugs were found for all variables; this demonstrated that with suprofen the antipyretic effect set in more rapidly than with the reference drug. No side-effects were observed in children treated with suprofen syrup. Two patients showed adverse effects, i.e. sweating and hypotension, during the treatment with metamizole. Due to its good antipyretic effect and good tolerability, suprofen appears to be particularly useful for symptomatic treatment of pediatric patients with fever caused by bacterial or virus infections.
