One hundred and fifty two patients presenting with palpable primary breast cancer were studied to evaluate accuracy of clinical assessment, mammography, and ultrasonography in measuring tumor size. The clinical, mammographic, and ultasonographic diameter of tumor size was compared to histological diameters. The histological diameter of tumors was 27.9+/-12.7mm. The average diameter of tumor on clinical assessment was 33.8+/-13.1mm and its correlation coefficient to the histological size was 0.73. The average size on the mammography was 21.4+/-9.0m and its correlation coefficient to the histological size is 0.71. The tumor size on the ultrasonography in 22 patients was is 22.3+/-10.4mm. The sonographic measurement dimonstrated the highest correlation coefficient (0.83). The clinical assessment overstimated the tumor size, but the mammogaphic and sonographic measurement understimated it compared with histological size. The combined measurement with clinical and ultrasonography could be useful method to estimate tumor size preoperatively. And when it is combined with clinical assessment, it is the most reliable and accurate technique.

PURPOSE: Retractile testis is considered to be a variant of normal testis in prepubertal boys. There is no agreed-upon management of retractile testis. The aim of this study was to provide data on the long-term outcomes of patients with retractile testis. MATERIALS AND METHODS: This study retrospectively reviewed the medical record of 43 boys who were referred for suspected undescended or retractile testis and were finally diagnosed with retractile testis between January 2001 and December 2008. All boys were biannually examined by a pediatric urologist to evaluate the presence of retractile, descended, or undescended testis and testicular volume. RESULTS: Of 43 boys, there were 22 boys with unilateral retractile testis (51.1%) and 21 boys with bilateral retractile testis (48.9%). Their mean age was 3.0+/-2.7 years and the follow-up duration was 4.4+/-1.7 years. Of 64 retractile testes, 29 (45.3%) succeeded in descending, 26 (40.6%) remained retractile, and 9 (14.1%) became undescended testis or of a decreased size requiring orchiopexy. The mean initial diagnostic age of the patients who underwent orchiopexy was 1.3+/-0.9 years; meanwhile, the mean initial diagnostic age of those who went on to have normal testis was 4.3+/-3.3 years (p=0.009). The mean follow-up duration was 3.6+/-1.5 years in the orchiopexy group, 4.0+/-1.4 years in the descended testis group, and 5.1+/-1.8 years in group with remaining retractile testis. CONCLUSIONS: Retractile testis has a risk of requiring orchiopexy. The risk is higher in the population diagnosed at a younger age. Boys with retractile testis should be observed periodically until the testis is descended in the normal position.

Torsion of the fallopian tube is an uncommon cause for acute low abdominal pain in female that is difficult to diagnose. Because it has no pathognomonic clinical symptoms or laboratory findings, a high index of suspicion is important when there is history of pelvic pathologic conditions or surgery. The early diagnosis and surgical treatment of the disease are mandatory to preserve oviduct.

PURPOSE: Percutaneous aspiration with sclerotherapy is widely used as a treatment for simple symptomatic renal cysts because percutaneous aspiration with sclerotherapy is minimally invasive and cost-effective. Sclerotherapy is usually performed in combination with aspiration due to the high recurrence rate, 30-70%, for the simple aspiration. We conducted an analysis of percutaneous aspiration with repeated sclerotherapy, and we report the results of sclerotherapy after percutaneous aspiration of simple renal cysts and we also review the results of the other previous studies. MATERIALS AND METHODS: Between January 2001 and April 2004, the results of percutaneous aspiration with repeated sclerotherapy in 39 cases of simple renal cysts were evaluated. We evaluated the operation time, the hospital stay, the success rate, the complication rate and the follow-up period. All patients were available for follow-up over a period of 3 months by conducting ultrasound exams and computed tomography (CT) scans. RESULTS: Complete collapse, partial collapse and recurrence of the renal cysts occurred in 24/39 (61.5%), 13/39 (33.3%), and 2/39 (5.1%) cases, respectively. The mean operative time was 50.3 minutes and the mean hospital stay was 4.5 days. The cost of two sessions of sclerotherapy was about 240,000 won and that of three sessions of sclerotherapy was about 300,000 won. The size of the cyst was not related to the rate of collapse. Any complication related to percutaneous aspiration with repeated sclerotherapy were not noted. CONCLUSIONS: With regard for the success rate and cost-effectiveness, percutaneous aspiration with repeated sclerotherapy is considered a primary treatment for simple symptomatic renal cysts.

OBJECTIVE: We used nucleated erythrocytes in maternal blood for prenatal determination of the fetal gender as the preliminary experiment for the screening of fetal genetic status and the BclI DNA polymorphism in an attempt to clarify the origin of erythrocytes in maternal blood. METHODS: In seventeen pregnant women, venous blood was withdrawn and the nucleated erythrocytes were recovered by magnetic activated cell sorting (MACS) and immunostaining. After isolation of nucleated erythrocytes by micromanipulation, we performed nested PCR for amelogenin gene to identify the fetal gender and performed BclI DNA polymorphism to clarify the origin of erythrocytes. RESULTS: We could amplify the minute DNA in a single cell by primer extension preamplification and nested PCR of amelogenin gene in 94 (48.7%) cells and could identify the fetal gender by 58.8%. BclI DNA polymorphism revealed that the several cells, which did not reveal the specific band of Y chromosome in spite of the pregnancy of male fetuses, must be the cells from mother. CONCLUSION: Through this study, we could conclude that several nucleated erythrocytes in maternal blood circulation can originate from mother, therefore we must develop the new method to identify the nucleated erythrocyte of fetal origin. Considering that we must apply for the larger number of pregnant women to screen, the procedure was multi-step and complex. Therefore, we must design the new scheme to utilize the nucleated erythrocytes in maternal blood.

The bacterial translocation is defined as the passage of viable bacteria or its toxin from the lumen of the gastrointestinal tract through the intestinal mucosa to other site of host. It is believed that bacterial translocation may lead to systemic infection and septicemia. The purpose of this study was to determine what factors in experimental surgical trauma lead to bacterial translocation. Two-nonth-old Wistar albino rats were divided into three groups: A-control; B-anesthesia only and C-anesthesia and surgery. After 24 and 48 hours, caval blood, mesenteric lymph nodes, liver, lung and spleen were harvested aseptically and cultured for aerobic organism. To exclude the possibility of contamination during surgical manipulation and harvesting, swab culture of peritoneal surface was performed. The bacterial translocation seldom occurred 24 hours after surgical manipulation. There was a significant increase in the number of animals with bacterial translocation in group C, 48 hours after manipulation and harvesting, swab culture of peritoneal surface was performed. The bacterial translocation seldom occurred 24 hours after surgical manipulation. There was a significant increase in the number of animals with bacterial translocation in group C, 48 hours after surgical manipulation. The majority of translocating bacteria was E. coli.

The purpose of this study was to examine the reliability and validity of a Korean form of Childhood Attention Problem(CAP) scale. CAP were administered to 98 normal elementary school students as control group and 98 attention deficit hyperactivity disorder patients. Male students showed high scores than female students in both subscale and total scores, but not statistically significant. There were no significant difference in CAP scale between male students and female students in attention deficit hyperactivity disorder patients. In the reliability test, the test-retest reliability coefficient was highly satisfactory and that of inattention subscale was 0.83, impulsivity subscale was 0.70 and total score was 0.82. In the reliability test by internal consistency, the Cronbach a coefficient was highly satisfactory and that of inattention subscale was 0.91, overactivity subscale was 0.89(p<0.05). The concurrent validity between CAP scale and ADDES-HV scale was 0.85 in attention deficit hyperactivity disorder patient group and 0.73 in normal control group(p<0.05). In discriminant validity test between attention deficit hyperactivity disorder patient group and normal control group, the patient group showed higher score(p<0.05). The total discriminant capacity of the patient group in CAP was 93.4%. In this point of view, CAP scale showed high reliability and validity in applying to Korean subjects and was proved to be the good and simple screening test tool for attention deficit hyperactivity disorder research and can help many young patient to treat early.

PURPOSE: Tumor size is a prognostic factor, as well as an important factor, in staging. Also, tumor size is a major factor in determining if a woman is a suitable candidate for various treatments, including a mastectomy or breast-conserving surgery. Thus, an accurate assessment of breast tumor size is important in making a prognosis and in planning treatment. METHODS: One hundred fifty-two patients presenting with palpable primary breast cancer were studied to evaluate the accuracies of clinical assessment, mammography, and ultrasonography in measuring tumor size. The clinical, mammographic, and ultrasonographic diameters of the tumors were compared to histological diameters. RESULTS: The average histological diameter of the tumors was 27.0+/-12.9 mm. The average diameter of the tumors on clinical assessment was 33.8+/-13.1 mm, and its correlation coefficient to the histological size was 0.73. The average size on mammography was 21.4+/-9.0 mm and its correlation coefficient to the histological size was 0.71. The tumor size on ultrasonography in 22 patients was 22.3+/-10.4 mm. The sonographic measurement demonstrated the highest correlation coefficient (0.83). The clinical assessment overestimated the histological tumor size, but the mammographic and sonographic measurement underestimated it. A combined measurement using both the clinical and the ultrasonographic methods slightly improved the correlation with the histological size (0.86). CONCLUSION: Ultrasonography could be a useful method for estimating tumor size preoperatively, and when it is combined with clinical assessment, it is the most reliable and accurate technique.
