50 children with a strong clinical suspicion of gastroesophageal reflux and 10 control patients were evaluated with gastroesophageal scintiscans. 500 muCi à 1 mCi of Tc sulfur colloid mixed the patients' routine milk or formula feeding was administered and serial images of the abdomen and thorax were obtained. A positive scintiscan was found in 35 patients (sensitivity 70%) and none of the controls (specificity 100%). A comparison of findings in 34 patients referred for both radiographic and radionuclide studies showed that barium studies were positive in 38% and radionuclide in 64.7%. We found this examination to be more sensitive that the standard barium radiography particularly in patients with respiratory symptoms. We concluded that the GE scintiscan is complementary to barium studies in the diagnosis of GE reflux. Pulmonary aspiration of gastric contents was detected in only a case of the 35 patients with documented GE reflux. A T 1/2 emptying gastric longer than 90 minutes (linear calculation) or 105 minutes (exponential calculation) is an indirect GE reflux test. This procedure is simple, safe more physiologic than other available examinations.

There were 50 children with a strong clinical suspicion of gastrooesophageal reflux and 10 controls patients evaluated with gastrooesophageal scintiscans. 500 microCi to 1 mCi of Tc sulfur colloïd mixed the patients routine milk or formula feeding was administered and serial images of the abdomen and thorax were obtained.

We conclude that the GE scintiscan is complementary to barium studies in the diagnosis of GE reflux. Pulmonary aspiration of gastric contents was detected in only a case of the 35 patients with documented GE reflux. A T 1/2 emptying gastric more long that 90 minutes (linear calculationation) or 115 minutes (exponential calcul) is an indirect GE reflux test. The diagnostic accuracy of all various procedures is reviewed and the scintigraphy value in the evaluation of GER in infants and children is discussed. This method is simple, safe more physiologic than other available examinations.

Thyroid localisation of an hydatic cyst is a rather rare phenomenon. Therefore, the occurence in our region of a thyroid hydatic cyst is noteworthy. In the present observation, the needle aspiration of an hypofixating nodule assured the diagnosis. Further more, this technique was harmless.

Biological abnormalities, in particular increased T3 and sometimes TSH, are frequently found in thyrotoxic patients treated with radioactive iodine and subsequently enthyroid. A high T3, associated with an increase in FT4 and a low TSH precedes a relapse. An increase in TSH may indicate progression towards hypothyroidism; even if FT4 and T3 levels are within normal limits. Caution must be exercised before affirming that an increased TSH with a high T3 and normal FT4 is indicative of thyroid equilibrium. At all events, the risk of hypothyroidism despite the use of small doses of radioactive iodine is such that the classical limit for the treatment of patients with thyrotoxicosis should be increased beyond the age of 40. In patients with a high TSH despite being clinically euthyroid, the use of thyroid extract in low dosage (50 mg/day) would appear to be desirable in avoiding the subsequent development of hypothyroidism.
