PURPOSE: Postoperative serial serum thyroglobulin (Tg) measurements on levothyroxine (L-T4) therapy in patients with differentiated thyroid carcinoma (DTC) is known to be useful in monitoring tumor progression or regression. The objective of this study was to evaluate the significance of serum Tg levels on L-T4 therapy after surgery. METHODS: To determine the basal serum Tg levels on L-T4 therapy after surgery in patients with DTC, Tg levels during the initial 2 year-period after surgery were analyzed retrospectively in 37 patients who had undergone a total thyroidectomy for papillary thyroid carcinoma with (Group 2) or without (Group 1) palpable cervical lymph node metastasis. The Tg levels had been measured 1 to 4 times for each patient with total of 53 and 35 times in Group 1 and Group 2 respectively. RESULTS: The basal Tg levels in Group 1 were all less than 4 ng/mL with 79.3% less than 2 ng/mL, and those in Group 2 were all less than 9 ng/mL with 71.4% less than 2 ng/mL. CONCLUSION: The data suggests that the postoperative serum Tg level of 10 ng/mL can be a useful reference value in long-term follow-up after total thyroidectomy for patients with DTC.

PURPOSE: We report one case of macular injury by Nd: YAG laser during aiming of the laser beam. METHODS: A 34-year-old man injured his right eye accidentally while aiming a Nd: YAG laser. He was referred to our ophthalmologic department because of diminished vision in the right eye at 2 hours after the accident. Central scotoma was noted. Best corrected visual acuity was 0.02 in the right eye. On fundus examination there were preretinal hemorrhage on the fovea, a full thickness macular hole of 1/3 optic disc diameter, parafoveal retinal edema and vitreous hemorrhage on inferior fundus. Seven days after the accident, a star shaped subretinal fibrosis and scar formation were seen on fundus examination and fluorescein angiography showed star shaped hyperfluorescence area on the fovea. Three months after the accident preretinal and vitreous hemorrhage were resolved and the macular hole was closed spontaneously, but the subretinal scar and fibrosis progressed and best corrected visual acuity remained as 0.02 in the right eye. RESULTS: Visual acuity was severely decreased due to Nd: YAG laser injury to the macula.

A prominent crista terminalis is a normal anatomic variant which consist of thick muscular bridge within the right atrium. However, it could be often misdiagnosed with an abnormal mass on the transthoracic echocardiography. The case report presented here, describe the findings of transthoracic echocardiography that suggested a right atrial mass in patients with pulmonary embolism. However, subsequent transesophageal echocardiography and cardiac computed tomography/magnetic resonance imaging differentiated a true right atrial mass from a prominent crista terminalis.

PURPOSE: To evaluate the efficacy of power Doppler ultrasonography (PDUS) in depicting renal infarction inrabbits during experimental renal segmental arterial occlusion, and to compare the results with those of CTscanning. MATERIALS AND METHODS: In 28 rabbits weighing 2.5-4kg, the segmental renal artery was occluded throughthe left main renal artery by embolization with Ivalon (Nycomed, Paris, France). Power Doppler ultrasonography andspiral CT scanning were performed before and at 2, 5, 8, 15, and 24 hours, and 3 and 7 days after occlusion of thesegmental renal artery. The location of infarcted areas and collaterals, as seen on PDUS and CT scans, wasevaluated by two radiologists. RESULTS: In all cases, as seen on power Doppler ultrasonography, infaretedareas-when compared with normal parenchyma, clearly demonstrated wedge-shaped perfusion defects in the kidney. Thelocation of the lesion closely corresponded to the location seen during CT scanning. After renal arterialocclusion, transiently congested capsular arteries, which were named 'capsular sign', were seen in 63% ofrabbits in the two and five-hour groups. No significant cortical rim sign was demonstrated on power Dopplerultrasonography, though it was noted on spiral CT at 15 and 24 hours, and 3 and 7 days after renal arterialocclusion. CONCLUSION: Power Doppler ultrasonography was useful for the diagnosis of renal infarction. Congestedcapsular artery seen in the early stage of renal infarction might be a characteristic finding of this condition,as seen on power Doppler ultrasonography.

PURPOSE: Traumatic rupture of the diaphragm is not easy to diagnose and often delayed. Delayed diagnosis of diaphragmatic rupture accompanied by higher chances of strangulation of herniated viscera which may result in higher morbility and mortality. The purpose of this study was to evaluate diagnostic accuracy of spiral CT, MRI and US for the diagnosis of diaphragmatic rupture in an animal model. MATERIALS AND METHODS: Small, medium, and large sized transabdominal diaphragmatic ruptures were surgically made in experimental rabbits and then followed up with spiral CT, MRI, and US at 1 day, 3 day, and 1 week after operation. RESULTS: US was superior to MRI or spiral CT in diagnosis of diaphragmatic rupture(P<0.05). The sensitivity and specificity were 94.4% and 92.9% for US, 54.0% and 85.7% for MRI, and 46.0% and 78.6% for spiral CT, respectively. The size of laceration was not related to diagnostic sensitivity in US. Sensitively of MRI and spiral CT increased as the size of laceration were larger, but no statistical significant was present(P>0.05). All experimental animals developed pleural effusion or hemothorax one day after operation. In acute phase. US and MRI were more sensitive than spiral CT in detecting diaphragmatic rupture. Spinal CT was more sensitive than US and MRI in delayed phase but without statistical significance(P>0.05) In the experimental rabbits with accompanying visceral hernia through the diaphragmatic defect, diagnostic accuracy was found equally high among three image modalities(P>0.05). CONCLUSION: This study indicates that US is the most accurate diagnostic method in detecting injury to the diaphragm in a rabbit model. The findings obtained in this experimental study can be applied to the diaphragmatic rupture of human being.

BACKGROUND/AIMS: The size and number of gallbladder polyps are used to differentiate between benign and malignant lesions before surgery. The objective of this study was to determine which polyps of the gallbladder should be operated upon and whether laparoscopic cholecystectomy is a safe and feasible method for gallbladder polypoid lesions of the gallbladder. METHODS: Data from 68 patients with polypoid lesions of the gallbladder treated by laparoscopic cholecystectomy at the Department of surgery, Pusan National University Hospital were reviewed retrospectively. the gallbladders were classified into four histologic groups. Clinical features, maximal diameter, and the number of lesions were compared among the groups. RESULTS: The mean maximal diameter of neoplasms was significantly larger than that of lesions in the nonneoplasm group. All four malignant lesions that were detected measured at least 1.5 cm. Univariate analysis showed that polypoid lesions of the gallbladder with neoplastic lesion correlated significantly with age, sex, and number of the lesions. Univariate analysis also showed that malignancy in polypoid lesions of the gallbladder correlated significantly with age, size, and number of the lesions. Multivariate logistic regression analysis showed that the age of the patient and the size of the lesion (> or =1.0 cm) are two independent factors in predicting neoplastic lesions in polypoid lesions of the gallbladder. The size of the lesion (> or =1.5 cm) is the only independent factor in predicting malignancy in the polypoid lesions of the gallbladder as shown by multivariate logistic regression analysis. CONCLUSION: Laparoscopic cholecystectomy is a safe and feasible method for gallbladder polypoid lesions. Neoplastic change in polypoid lesions of the gallbladder should be considered when a patient older than 50 years of age has a polypoid lesion larger than 1.0 cm. Cancer should be suspected when a polypoid lesion of the gallbladder is larger than 1.5 cm.

The authors present a case of unilateral agenesis of internal carotid artery associated with an aneurysm at the unusual site. A 22-years old female was admitted with sudden headache and nausea. She was alert on admission and no focal neurologic deficit was detected. Brain computed tomography(CT) scan showed subarachnoid hemorrhage. In the cerebral angiography, right internal carotid artery was absent and an aneurysm was arisen from the junction of the right middle cerebral artery and posterior communicating artery. The blood supply of the right anterior cerebral artery was maintained from the left internal carotid artery via the anterior commuicating artery. The territory of the right middle cerebral artery was supplied from the basilar artery through enlarged right posterior communicating artery. Direct clipping of the aneurismal neck was performed through right pterional approach. In the postoperative high resolution CT scan, there was no carotid canal in the right skull base suggesting agenesis of the right internal carotid artery.
