PURPOSE: To evaluate the result of distal clavicle fracture treated by Hook plate (LCP clavicle hook plate, Synthes(R), Paoli, Switzerland). MATERIALS AND METHODS: 10 patients with distal clavicle fracture treated by Hook plate from April 2008 to March 2010 were analyzed. The average follow-up period was 10 (range 4 to 26) months. The reduction was qualified and evaluated according to the immediate post-operative, final radiographs. We analyze the result by UCLA score and Kona's functional evaluation. RESULTS: By radiologic evaluation, all cases showed anatomical reduction and solid union. By Kona's functional evaluation, there are 7 cases with excellent results, 3 cases with good results. The UCLA score was average 33.3 (range 29 to 35) points followed by 6 excellent cases, 4 good cases. As complication, 1 case showed post-operative clavicle shaft fracture and 1 case showed acromial osteolysis on X-rays. We found no complications such as skin irritation, infection, loosening of screws, and plate failure. CONCLUSION: The Hook plate fixation for distal clavicle fracture is considered effective method for satisfactory reduction and rigid fixation, a lower incidence of nonunion and excellent clinical result.

BACKGROUND: Malignant thyroid tumors may mimic the clinical symptoms and signs of a non-malignant tumor in the early course of the disease. The choice of the treatment modality for a thyroid tumor can be based on exact interpretation of FNAC (fine needle aspiration cytology) and frozen section. METHODS: We have experienced 237 cases of thyroid tumors during the past ten years at St. Columban hospital. From September 1988 to August 1998, subjects were selected and a retrospective study was done. RESULTS: (1) Of the 237 cases in this study, 194 had non-malignant lesions and 43 had malignant lesions, a ratio of 4.5:1. (2) The female to male ratio was 9.2:1 with non-malignant lesions (female: 195/male: 19) and 9.8:1 with malignant lesions (female: 39/male: 4). (3) The age distribution was the 4th to the 6th decades, regardless of the nature of the lesions. (4) The duration of disease was within 3 months with 42.2% of subjects, and 71.8% of subjects came within first year of disease, regardless of the nature of lesions. (5) Thyroid function tests showed no abnormality with most of the patients, regardless of the nature of lesions. (6) Fine needle aspiration cytology biopsy showed a sensitivity of 32.7%, a specificity of 100%, and an accuracy of 90.8%, and revealed preoperative diagnostic validity. (7) Ultrasonography of the neck, showed a sensitivity of 32.7%, a specificity of 88.1%, and an accuracy of 77.4%, and had no diagnostic value. (8) With benign lesions, adenomatous goiters were most common (96 cases), and with malignant lesions papillary carcinomas were predominant (36 cases). CONCLUSIONS: FNAC and frozen section are valuable preoperative and intraoperative diagnostic tool for thyroid tumors.

The search for tumor-avid agents for use in nuclear medicine imaging is an ongoing field of importance. The purpose of this study was to determine the affinity for radiolabeled vitamin B12 by a wide histologic variety of tumor types in mice. Seventeen different types of tumor were grown subcutaneously in female Balb/C or Balb nu/nu(nude) mice. When the tumors reached about 1 cm in diameter, mice were injected intraperitoneally with 57Co-vitamin B12. Twenty-foul hours later, the mice were sacrificed. Organs and tissues were removed, weighed, and activity per mg determined by gamma counter. Values represented cpm/mg tissue that was normalized to 20 grams body weight for each mouse. A wide variety of tumor types showed significant uptake and concentration of 57Co-vitamin B12, as evidenced by tumor:tissue activity ratios. For many tissues of great importance in terms of background(bone, muscle, blood), the tumor:tissue activity ratios of uptake were high. These data strongly suggest that further efforts to evaluate the utility of radiolabeled adducts of vitamin B12 for clinical use in oncologic imaging are warranted.

Background: Multiple endocrine neoplasia type I(MEN I) is a rare, eomplex, and potentially lethal disease. In Korean, only five anecdotal cases were reported as yet. The authors rescently experienced four cases of MEN I, and analysed the clinieal characteristics of MEN I in Koreans. Methods: The authors evaluated nine cases of MEN I, retrospectively. Four cases were analysed by clinical records in patients admitted to Asan Medical Center and five cases were reviewed by previously reported Korean literature from 1986 to 1995. Results: The average age was 39 years(ranged from 33 to 59 years). Eight of the nine patients had hyperparathyroidism documented by elevated serum calcium and PTH level with or without evidence of parathyroid mass. Initial presenting manifestations were symptomatic urinary stone, hypoglycernia due to insulinoma, hypogonadism, acromegaly, or peptic ulcer. Eight of nine patients had pancreatic islet cell tumors, and three of them were be malignant by radiologic and/or pathologic findings. The pancreatic tumors produced various hormones, such as gastrin, insulin, glucagon, or combination of them. Six of the nine cases had pituitary lesion. The most cornmon pituitary tumor was prolactinoma and the remaining was GH or GH and TSH producing tumor. In addition to the major components of MEN I, four had adrenocortical hyperplasia or adenoma and two had carcinoid tumor. There was only one familial case. Conclusion: The clinical charateristics of MEN I in Korean are mostly not different from the previous reports except older age at diagnosis, more comrnon adrenal involvement(44%) and gastrointestinal carcinoid tumor(22%). Although only one case was familial, more cases could be found if careful screening were done for the family members of the MBN I patients. In addition, screening and close follow up for endocrine pancreatic tumors are required for MEN I patients without detectable pancreatic lesion becau~se the malignant potential of pancreatic tumors has beeome an increasing concem for the prognosis of MEN I.

PURPOSE: Combined resection of an invaded organ in advanced gastric cancer (AGC) with infiltration of adjacent organs is essential to achieve R0 resection. However, when the tumor invades the head of the pancreas or duodenum, R0 resection interferes with the lower resectability and results in a higher morbidity. Wereviewed these cases retrospectively and considered the proper extent of the surgical resection. MATERIALS AND METHODS: We retrospectively analyzed cases where patients underwent surgery for gastric adenocarcinoma at the Department of Surgery, Presbyterian Medical Center, between January 1998 and December 2003. Among the 45 patients who were suspected to have pancreatic head or duodenum invasion by a primary tumor or metastatic lymph nodes based on the operative findings, we included 22 patients without incurable factors. The patients were classified into three groups: 4 patients that underwent a combined resection (PD group), 12 patients that underwent a palliative subtotal gastrectomy (STG group) and 6 patients that underwent bypass surgery only (GJ group). We analyzed the clinicopathological features, operative data and results. RESULTS: The patients of the PD group achieved R0 resection by PD with D3 Dissection in all Patients. A pancreatic fistula was observed in one patient (morbidity 25%). There was no surgery-associated mortality (mortality 0%). All patients of the PD group were in stage IV. However, the 2-year survival rate (SR) was 75% and the 5-year SR was 50%. Six patients of the STG group underwent surgery with marginal resection and the other six patients of the STG group had a positive distal resection margin. The 2-year SR was 41.7% and the 5-year SR was 16.7%. Most of the patients of group GJ were of old age (mean age: 72.7+/-8.6 years) or had chronic diseases. The 2-year SR was 0%. CONCLUSION: Combined resection of the pancreas and duodenum in AGC with pancreatic head invasion is relatively safe with moderate morbidity and a lower mortality. One can expect long-term survival if combined resectionis performed in cases without incurable factors.

OBJECTIVES: The purpose of this study was to examine the automatic attentional bias to disease/body-related stimuli in individuals exhibiting somatization tendencies using Event-Related Potential (ERP). METHODS: The participants were classified according to somatization and control groups based on the somatization symptom scales of the Symptom Checklist-90-Revised and Somatosensory Amplification Scale scores. ERP were recorded in the somatization and control groups while participants were performing the task to respond with neutral (standard stimuli) or disease/body-related words (target stimuli). We compared N100, P200, and P300 ERP components between the two groups. RESULTS: In the somatization group, the reaction times to disease/body-related words were faster than for neutral words. In ERP analysis, N100 to standard stimuli was not observed in the somatization group. The somatization group showed higher P200 and P300 amplitudes to target stimuli than standard stimuli. On the contrary, in the control group, no difference in P200 and P300 amplitudes was observed between target and standard stimuli. CONCLUSION: It is suggested that individuals exhibiting somatization tendencies have automatic attentional bias to disease/body-related stimuli and interpret disease/body-related stimuli as self-relevant stimuli.
