PURPOSE: The purpose of this study was to evaluate and compare the scintigraphic findings and diagnostic accuracy of double-phase Tc-99m sestamibi scan in primary and secondary hyperparathyroidism (HPT). MATERIALS AND METHODS: We retrospectively reviewed 16 cases of primary (18 lesions) and 11 cases of secondary HPT (44 lesions) who underwent Tc-99m-sestamibi scan before the surgical intervention. Scan was performed using LEM camera (Siemens, Germany) after the injection of 740MBq of Tc-99m sestamibi. Routine image consisted of baseline and 3-hour delayed images and each image was obtained using both parallel and pine hole collimator. The study population was 27 patients (male/female=5/22, age: 49.1+/-10.8). RESULTS: Eighteen lesions of primary HPT consisted of 13 adenomas and 5 hyperplasias, while all lesions of secondary HPT were hyperplasias. Among the case of primary HPT, we could detect all the lesions of 13 adenomas but only 2 lesions of 5 hyperplasias (40%) could be detected by double phase scintigraphy. Three cases of primary lesion showed decreased uptake in delayed images compared with baseline. The sensitivity, specificity, positive predictive value and accuracy of primary and secondary HPT were 58.8% (10/17), 83.3% (10/12), 83.3% (10/12), 75.9% (22/29), and 37.5% (15/40), 50% (2/4), 88.2% (15/17), 38.6% (17/44), respectively. Overall sensitivity, specificity, positive predictive value and accuracy were 43.9% (25/57), 75% (12/16), 86.2% (25/29), and 53.4% (39/73). There were no statistical difference between the weight of primary and secondary HPT lesion (p>0.05). CONCLUSION: Tc-99m sestamibi scan is fairly good modality to detect parathyroid lesion in patient with primary HPT before the surgical intervention. However, since some of cases may reveal decreased uptake in delayed image, a careful attention to the findings of baseline images may be helpful. Still the low accuracy of sestamibi scan in diagnosis of secondary HPT prohibits routine use of it for this disease.

The Marfan syndrome is classified as a heritable disorder of connective tissue with clinical and pathological alterations involving supporting elements. In its classic form, the Marfan syndrome is associated with abnormalities of the eye(ectopia lentis), aorta(aortic dilatation and aortic regurgitation) and skeleton(dolichostenomelia, arachnodactyly and pectus deformity). The authers have experienced a case of marfan syndrome recently. The patient was 30-years-old male complaining of anterior chest pain radiating to upper back. Physical examination showed tall status, increased length of the limbs as compared with the trunk and arachnodactyly. On auscultation, heart sound was normal without murmur. He wore glasses because of moderate myopia. Roentgenogram of the chest P-A revealed normal cardiac and aortic contours and lung fields. Left lateral view of chest X-ray revealed concave depression of sternum showing mild pectus excavatum, fusiform dilatation of aorta from aortic root to mid portion of thoracic aorta and resulting in obliteration of retrosternal clear space. Echocardiogram demonstrated moderate dilatation of aortic root A-P diameter(4.5cm) without aortic or mitral valvular abnormalities and normal size of left ventricular cavity(EDD:5.3cm). These data coupled with a distinct family history could permit the diagnosis of Marfan syndrome.

We studied serum uric acid in 120 patients of essential hypertension visiting Department of Internal Medicine of Seoul Red Cross Hospital from October 1985 to November 1986 and analyzed its values in terms of various clinical and laboratory parameters. The results wereas follows; 1) The mean concentration of serum uric acid and incidence of hyperuricemia were 6.5+/-1.86mg%, 50.8% in hypertension group and those of normal control were 3.75+/-1.27mg%, 13.3%, respectively with significant high values in hypertension group. 2) The mean concentration of serum uric acid and the incidence of hyperuricemia were significantly correlated with the levels of diastolic blood pressure but there was only correlation between the incidence of hyperuricemia and the level of systolic pressure. 3) The mean concentration of serum uric acid and the incidence of hyperuricemia were significantly correlated with the level of BUN and serum creatinine, especially more in serum creatinine. 4) The mean concentration of serum uric acid and the incidence of hyperuricemia were not correlated with each level of serum cholesterol and triglyceride. 5) There was significant correlation between mean concentration of serum uric acid and abnormal urine finding but not in incidence of hyperuricemea.
