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.

To evaluate the reproducibility of the Ambulatory Electrocardiography (AECG), we examined the consistency rates of premature beats between the baseline AECG's and the repeat AECG's in 23 patients who underwent AECG's times within 1 year. 12 patients were male and 11 patients were female. Their mean age was 48 years. (Range ; 20 years-75 years) The time interval between both AECG's was 1 month 20 days. (Range ; 1 day-9months) They did not take any antiarrhythmic druge during the observation period except 4 patients who were taking calcium channel blockers or beta receptor blockers for hypertensive heart disease or ischemic heart disease. The consistency rate of both frequency and complexity of ventricular premature beats was 52%. The consisency rate of both frequency and complexity of supraventicular premature beats was 35%. These consistency rates seemed to vary as the time interval between both AECG's differed. In the case of ventricular premature beats, the consistency rates of 1 day, 8 days and 5 months as the time interval were 100%, 38% and 14% respectively. In the case of supraventricular premature beats, the consistency rates were 50%, 25% and 29%. We concluded that the reproducility of the AECG was low and this reproducibility became lower as the time interval between both AECG's became longer and that hese facts had to be considered when the effect of the antiarrhythmic drugs was evaluated.

Acromioclavicular joint dislocations are frequently seen with industrial accident, sports activity and traffic accident. Various operative treatment modalities have been suggested. The purpose of this study is to compare the clinical results of two operative methods in young patients with acromioclavicular dislocation. The authors analyzed the clinical and radiological results of 30 patients with acromioclavicular dislocation, in whom 15 patients were treated by acromioclavicular reduction & fixation with K-wire(Phemister procedure) and 15 patients by acromioclavicular reduction & coracoclavicular fixation by cancellous screw with coracoclavicular ligament repair(Bosworth procedure) from March 1989 to September 1993 at Ansan Hospital, Korea University. They were followed up more than 12 months. The results obtained were as follows: 1. The difference of coracoclavicular distance compared with normal side after operation was 2.6mm in Phemister operations and 1.6 mm in Bosworth operations. And these differences were not changed at follow up significantly. 2. The complications were two K-wire migrations, one superficial infection, and one recurred gross deformity after pin removal in Phemister operations and two mild upward migrations of screw after Bosworth operations. 3. We obtained similar good results after Phemister and Bosworth operations. But less complications were visible, and anatomical reduction and early ROM exercise were possible after Bosworth operations.
