PURPOSE: Kimura's disease is an inflammatory condition of unknown etiology which usually occurs in salivary glands and cervical lymph nodes. This study was undertaken to evaluate the radiologic characteristics of Kimura's disease using CT and MRI. MATERIALS & METHODS: We evaluated CT & MR of 10 patients with histologically proved Kimura's disease in the head and neck. Six males and four females between 16 and 58 years old (mean age, 37.6 years) were included. Contrast enhanced CT scan was performed in all, and spin-echo MRI was performed in 2 patients. RESULTS: Both CT and MRI demonstrated the distinctive sites of involvement that were major salivary glands (4 cases) and lacrimal gland (1 case), periglandular soft tissue (8 cases), and cervical lymph nodes (8 cases). Majority of soft tissue lesions were ill-defined with infiltration to adjacent fascial planes, but nodal lesions were relatively well-defined and homogenous. The lesions were iso-intense on Tl-weighted image and hyper-intense on T2-weighted image. All but a few nodal lesions showed variable degree of contrast enhancement on CT and MRI. CONCLUSION: In diagnosis of Kimura's disease, CT & MRI of head & neck, especially salivary glands, are useful. In cases of recurrent periglandular soft tissue mass with contrast-enhancing cervical lymphadenopathy in adult patients, Kimura's disease should be included in the differential diagnosis.

BACKGROUNDS:Bile reflux gastritis can occur when pylorus ablation is associated with bile stasis in the stomach. It can also occur with a gastrojejunostomy when bile is continuously poured into the gastric remnant after a vagotomy and an antrectomy. The diagnosis of bile reflux gastritis can be made only when the patient has bile gastritis documented on biopsy; the simple observation of a bile-stained mucosa in a gastric remnant is not sufficient to make the diagnosis of bile reflux gastritis. METHODS: Technetium-99m diisopropyl iminodiacetic acid (Tc-99m DISIDA) scintigraphy was used to study bile reflux into the gastric remnant in 31 patients with gastric operations. All patients had gastrofibroscopic biopsies in order to identify the bile reflux gastritis. RESULTS: Tc-99m DISIDA Scintigraphy identified bile reflux in 15 (83.2%) of 18 patients after a subtotal gastrectomy and a Billroth II gastrojejunostomy. Hewever, no bile reflux occured in either the 10 patients with a hemigastrectomy plus Billroth I gastoduodenostomy or the 3 patients with a truncal vagotomy plus pyloroplasty. Also, gastrofibroscopic biopsies identified bile reflux gastritis in only 3 patients (9.7%) with a subtotal gastrectomy plus Billroth II reconstruction. CONCLUSIONS: The patients who underwent a subtotal gastrectomy and Billroth II reconstruction showed higher bile reflux rates than did the patients who underwent a hemigastrectomy plus Billroth I reconstruction and a truncal vagotomy plus pyloroplasty (p<0.05). Also, only 9.7% of the postgastrectomy patients developed bile reflux gastritis.

By Enzinger and Weiss classification, 664 cases of soft tissue tumors, which were confirmed histologically at the department of pathology of Hangang Sacred Heart Hospital from Janusry 1979 to December 1988, were analyzed statistically. The results were as follows : 1. Of the 664 cases, 261 cases (39.3%) were consulted at the Department of General Surgery, 124 cases (18.7%) were consulted at the Department of Orthopedic Surgery, 115 cases (17.3%)were consulted at the Department of Dermatology. 2, Of the 664 cases, 631 cases (95%) were benign and 33 cases (5%) were malignant. 3. The most common benign tumor was lipoma, which was followed by hemangioma and lymphangioma. Among malignant tumors liposarcoma was the most common one, followed by malignant fibrous histiocytoma. 4. The distribution of age of benign tumor was relatively even from childhood to old age but that of malignant tumor showed highest prevalence in 7th decade. 5. The distribution of sex of benign tumor showed male to female ratio of 1: 1.1 but that of malignant tumor showed male to female ratio of 1.5: l. 6. The predilection sites of benign tumors were head, neck and trunk, but those of malignant tumors were lower extremities and trunk. 7. Kinds of soft tissue tumors consulted at the Department of Dermatology were hemangioma, neurofibroma, lipoma, dermatofibroma, ymphangioma, leiomyoma, juvenile xanthogranuloma, xanthoma, keloid and neurilemmoma.

PURPOSE: Most stones in the urinary tract can be managed by SWL, percutaneous nephrolithotomy and ureteroscopic lithotripsy, however in some patients whose calculi were not managed by these methods, open surgery must be considered. We performed ureterolithotomy using laparoscopy assisted small incision in upper ureter stone and compared their efficacy with conventional ureterolithotomy. MATERIALS AND METHODS: 10 patients whose stones were not fragmented by SWL or who showed intractable pain were managed by laparoscopy assisted small flank incision of 5cm without insufflation of gas(group I). We compared the efficacy of this procedure with 10 patients who underwent conventional ureterolithotomy(group II) in operating time, the number of analgesics required for the management of postoperative pain control, hospital stay, immediate complication and medical expenses. RESULTS: The stones were successfully removed in all patients. The operating times ranged 40 to 150 min(mean 98.5) in group I and 60 to 190 min(mean 83.0) in group II. The mean requirement of analgesics and hospital stay after surgery were 2.4 times and 3.4 days in group I, and 8.4 times and 6.8 days in group II respectively. The mean medical expenses were 803,000 won in group I and 956,000 won in group II. No intra-operative complication was noted in group II, but 1 patient showed urine leakage in group I, which was managed by placement of ureteral catheter. In immediate postoperative complications, 1 patient complained wound pain persisted over 1 month in group I but 6 patients in group II. CONCLUSIONS: Ureterolithotomy using laparoscopy assisted small incision is another modality in the management of upper ureter stone which was not managed by SWL, percutaneous nephrolithotomy and ureteroscopic lithotripsy. Furthermore, this procedure is safe and effective, and offers significant advantages in hospital stay, requirement of analgesics, and medical expense.

The purpose of this study is to observe the longitudinal changes in BMI (Body Mass Index) of obese and non-obese 3rd. grade high school students in Seoul for 12 years and to see the trends of overt weight gain in obese adolescents. The results are as follows; 1. The average annual increasing rates of body mass indices in male students were 1.14kg/m2 in obese group and 0.59 in non-obese group. In female students, the average annual increasing rates of body mass indices were 0.93kg/m2 in obese group and 0.53kg/m2 in non-obese group. 2. The change rate of BMI for 12 years was significantly higher in obese group than non-obese group. 3. Puberty had less influence on the change rate of BMI in obese group compared to non-obese group. 4. In obese group, 71.8% of the variance in BMI at 17 can be predicted by BMI at 16 years in male students. In female students 44.4% can be predicted by BMI at age 16. 5. Among the 17-year-old obese students, 58.8% of the males and 56.2% of females were found not to have been obese at 7 years of age. 6. Among the 17-year-old obese students, those who were obese at 7 years of age were found to have higher BMI at later ages than those who were in the non-obese group. Obese adolescents were more likely to be obese in their childhood than non-obese group. There was no optimal age for the significant weight gain and the increasing rate of BMI was constantly higher in obese group than in non-obese group. Due to the fact that child obesity in early age contributes to obesity in adolescence, close observation is advised on the other hand, a large proportion of obese adolescents can be preventable by early interventions, because about 50% of obese adolescents were not obese in early elementary school age.

Subclinical hyperthyroidism and subclinical hypothyroidism are characterized by abnormal thyroid stimulating hormone (TSH) with normal free thyroxine. Subclinical thyroid diseases, to date, have received less attention compared with other thyroid diseases since they are asymptomatic. This study aimed to verify the association between subclinical thyroid diseases and cardiovascular diseases (CVDs) risk score in the Korean population. This was a population-based cohort study using data collected from 3,722 subjects (aged ≥ 30 years) during the 6th Korea National Health and Nutrition Examination Survey (KNHANES VI; 2013–2015). Gender-specific Framingham risk scores were calculated to identify the association between subclinical thyroid diseases and 10-year CVD risk score. Complex survey, with consideration of sampling weight, was analyzed using generalized linear models after stratification by gender. The TSH reference range was between 0.61 and 6.91 mIU/L in this study. TSH showed a positive association with the 10-year CVD risk score only in the female population (P = 0.001). There were significant differences in the least squares means of 10-year CVD risk score by the effect of subclinical hypothyroidism compared with euthyroidism (normal group) in females, after adjusting for body mass index, white blood cell, and urine iodine (P = 0.006 and Bonferroni corrected P = 0.012). In conclusion, subclinical hypothyroidism is associated with increased 10-year CVD risk score in the female Korean population aged 30 years or more. Therefore, we recommend to clinically checkup major CVD risk factors in female patients with subclinical hypothyroidism aged 30 years or more.

PURPOSE: Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We stuided correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. MATERIALS AND METHODS: 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. RESULTS: In All of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas involved in 9 cases, and other organ in 4 cases. CONCLUSIONS: The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.
