Graves' disease is an autoimmune disorder that comprises the triad of diffuse toxic goiter, ophthalmopathy, and infiltrative dermopathy, although all three are not necessarily present in a given patient. The manifestations of Graves' disease vary, depending on the patient's age and other factors. Choice of therapy is influenced by the patient's age, history of heart disease, pregnancy status, expectations, and preferences. Most patients are treated with either radioactive iodine (sodium iodide I 131 [Iodotope]) or the antithyroid drugs propylthiouracil or methimazole (Tapazole). Antithyroid drugs may be more effective in producing long-term remission if levothyroxine sodium (Levothroid, Levoxine, Synthroid) is added to the regimen after the patient becomes euthyroid. Hypothyroidism occurs in many patients following 131I therapy but is also seen in a substantial number of patients who have been treated with thyroidectomy and even in some who have taken antithyroid drugs. Long-term follow-up is necessary, regardless of type of initial treatment, and should include an annual physical examination and measurement of serum concentrations of thyrotropin and the free thyroxine index, both of which should be maintained in the normal range.

A quasi steady-state noninvasive, radioisotopic technique for measuring regional lung water distribution in man is described. The method depends upon the dilution principle. 123I labelled human serum albumin (HSA) and sodium iodide (NaI) were injected intravenously, allowed to mix completely within the body fluids and then counted externally over the chest. The size of each compartment to which the markers are confined was calculated from the external count rate and the isotopic concentration of the marker in plasma. 123I-HSA was used to estimate intravascular water and 123I-NaI extracellular water. Ratio analysis of the differential attenuation of the two photoenergies of 123Iodine (29 keV, 159 keV) by the lung and chest wall was used to estimate the absolute amount of isotope in the lung, independent of chest wall contribution, after validation by phantom studies. Regional pulmonary plasma (PPVr) and interstitial (PIVr) fluid volumes in normal subjects were 7.1 +/- 1.4 and 7.6 +/- 1.3 ml.100 cm-3 lung (mean +/- SD; n = 13) at mid-tidal volume, respectively. In patients with the adult respiratory distress syndrome, PPVr and PIVr were 7.0 +/- 2.9 and 15.9 +/- 4.6 ml.100 cm-3 lung (n = 18), respectively. The pulmonary artery wedge (Paw) pressure was normal (12.5 +/- 2.5 mmHg; n = 5). In patients with pulmonary oedema due to left heart disease, PPVr and PIVr were 7.2 +/- 2.7 and 12.1 +/- 3.7 ml.100 cm-3 lung (n = 8), respectively. The mean Paw pressure in this group was high (28.5 +/- 3.9 mmHg).
