Real-time ultrasound-guided fine-needle aspiration biopsy in 137 solid breast masses was performed. Sonographic findings were categorized into three group and aspirates were categorized into three cytologic groups. The cytologic result was reported benign masses (cytologic group 1) in 71 cases (52%), malignant masses (cytologic group 2 and 3) in 44 cases (32%) and insufficient specimens in 22 cases (16%). Insufficient specimens were treated as benign masses. Excisional biopsy in 44 malignant masses and 3 benigh masses according to cytologic results, clinical findings and follow up study was performed. The result was reported 41 malignant masses and 6 benign masses. Based on cytologic criteria, sensitivity for detection of malignancy was 93% and specificity was 94%. In conclusion, the high specificity provided by ultrasound-guided fine-needle aspiration biopsy could markedly reduce unnecessary surgical excisions for benign masses and it should be routinely performed, since it can give physical and emotional benefits to patients and lead to earlier and cost effective diagnosis of breast cancer.

PURPOSE: Doppler-guided hemorrhoidal artery ligation and recto-anal repair (DG-HAL & RAR) is known for low recurrence, high patient satisfaction, and less postoperative pain. The purpose of this study is to analyze the 1-year follow-up results in patients who underwent a DG-HAL & RAR and to establish the benefits of the procedure. METHODS: Among the hemorrhoid patients who were admitted to our hospital from March 2008 to May 2010 and who underwent a DG-HAL & RAR, 97 patients who were followed up for a year were investigated. Recurrence, complications, admission period, difference in preoperative and postoperative pain, operation time, and time to return to daily activities were investigated. RESULTS: The average admission period was 1.6 +/- 1.1 days. Pain at postoperative day 7 showed no significant difference from preoperative pain (P > 0.05). The operation time was 34.0 +/- 7.3 minutes on average, and return to daily activities was timed at 2.3 +/- 2.0 days postoperatively. At the one year follow-up, no serious complications were noted, and preoperative symptoms recurred only in 14 patients (14.4%). CONCLUSION: In most patients with hemorrhoids, excluding those with severe prolapsed hemorrhoids, less pain, no serious complications, and good long-term outcome can be expected from a DG-HAL & RAR.

Esophageal duplication is the congenital developmental anomaly manifestated as cystic or tubular type. The tubular esophageal duplication found at adult is extremely rare. A patient with tubular esophageal duplication is reported. A 37 years old male developed epigastric pain aggravated at hunger state from 2 monthes before administration. Gastrofiberscopy was done, and we could found the tubular esophageal duplication at 25 cm from incisiors. Esophagogram exposed the tunnel communicated with right anterior side of normal esophagus at upper and lower part of the tubular pathway with the length of 6 cm at T4-5 level. The microscopic finding of the tubular lumen revealed normal esophageal wall structure involving the outer part of muscle layer. Surgical resection was not done for the lesion was small and no symptom due to esophageal duplication was present. And so, the authors report this case as a tubular esophageal duplication with a literature review.

Purpose: Compressive hip dressings have been used to decrease the amount of postoperative bleeding after total hiparthroplasty. However, there is no data showing that a compressive dressing is effective. This study evaluated the effect of compressive dressings on the level of postoperative bleeding after total replacement arthroplasty. Materials and Methods: This prospective randomized clinical trail included 80 consecutive primary total hip arthroplasties in 72 patients. The 80 hips were randomly assigned to a compressive dressing group or a non-compressive dressing group using a table of random numbers. Forty-two hips in 37 patients were treated using the compressive dressing and the remaining 38 hips in 35 patients were treated using a non-compressive dressing. The patients were followed up for an average of 10.3 months. In all patients, a hemovac suction drain was inserted postoperatively. Results: The mean level of bleeding was 626.6 mL in the compressive group and 693.8 mL in the non-compressive group. There was no statistical difference between the two groups (P=0.416). Moreover, the incidence of postoperative complications including dislocation, nerve injury, symptomatic deep vein thrombosis and heterotopic ossification was similar in both groups. Conclusion: These results suggest that the compressive dressing has no significant effect on the amount of postoperative bleeding and clinical results after total hip arthroplasty.

BACKGROUND: Endometrial carcinomas are pathogenetically classified into two major types; endometrioid carcinoma (EC) and serous carcinoma (SC). The most frequently altered gene in EC is the PTEN tumor suppressor gene (TSG). SC is usually associated with mutations in the p53 TSG. METHODS: To further determine the role of PTEN and p53 mutation in endometrial carcinogenesis, the analysis of 33 endometrial carcinomas, including 28 ECs and 5 SCs, for loss of heterozygosity (LOH) on 10q23 and for mutation in all 9 coding exons of PTEN and the 5-8 exons of p53, using SSCP-PCR methods was carried out. RESULTS: LOH was detected in at least one marker in 12 (54.5%) of 22 ECs, but in only one (20.0%) of 5 SCs. Somatic PTEN mutations were detected in 10 (35.7%) of 28 ECs. PTEN was altered in 67.9% of ECs and in 20.0% of SCs, including those with 10q23 LOH. No PTEN mutations were found among the SCs. Somatic p53 mutations were detected in 2 (7.1%) of 28 ECs and 3 (60.0%) of 5 SCs. CONCLUSIONS: PTEN gene alterations contribute to the pathogenesis of an endometrioid subtype of endometrial carcinoma, but not to the serous type. In contrast, p53 plays an important role in the pathogenesis of SCs.

OBJECTIVES: Since the 1990s, drug-resistant bacteria have become common pathogens of hospital-acquired infections. In recent years, healthcare-associated infections have come to the fore, and it is reported that distribution rates of these bacteria are comparable to those of hospital-acquired infections. However, there have been few studies on differences in resistant bacteria depending on the size of hospitals. Thus, the authors studied differences in drug-resistant bacteria between a tertiary hospital and smaller medical institutions. METHODS: We retrospectively analyzed the clinical findings and sputum culture results of patients transferred from tertiary hospitals (group A, n=74) and those transferred from smaller medical institutions (group B, n=65). RESULTS: The number of patients with malignancy was higher in group A than in group B. The length of intensive care unit stay was longer in group A than in group B. Antibiotic therapy and mechanical ventilation were more frequently used in group A than in group B. There were no significant differences between the 2 groups in bacterial species (Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa) and their resistance rates to carbapenem, while there were significant differences between the 2 groups in the bacterial species (Acinetobacter baumannii) and its resistance rate to carbapenem. CONCLUSION: In this study, there were significant differences between the 2 groups in the bacterial species and resistance rates to carbapenem for A. baumannii infection unlike other bacterial infections. Further studies on risk factors and patient classification are needed to confirm our results.

STUDY DESIGN: This is a retrospective study analysing the results of Buck's operation for spondylolysis. PURPOSE: To analyze the results of Buck`s methods as a treatment for symptomatic spondylolysis clinically and radiographically. MATERIALS AND METHODS: Between March 1992 and March 1999, 12 patients with symptomatic spondylolysis were treated with Buck`s method. Surgical indication was 1)under 30 years of age, 2) patients with intractable low back pain without sciatica who did not response to conservative treatment for over 6 months, 3) without disc degeneration in lumbar MRI, 4) without instability in lateral flexion-extension view. The average age was 23 years and the follow-up periods ranged from 12 months to 54 months, mean 25 months. We confirmed union of defect and loosening or breakage of screws in preoperative, postoperative and the final radiographs, and in bone SPECT. And we analyzed symptomatic improvement by subjective assessment guidelines of Henderson clinically. RESULTS: Radiologically, union of defect by trabeculation was seen in 8 patients, in 2 patients unilaterally. In bone SPECT, union of defect was seen in 5 cases among 7 cases postoperatively. Average periods of union were 3.1 months(2.5-6.2 months). There was no loosening of screws, but in 1 patient breakage of screws and nonunion was seen 8 months postoperatively. Clinically, 10 patients(83.3%) were rated as excellent or good-5 patients excellent, 5 patients good-according to subjective assessment guidelines of Henderson. CONCLUSION: It is suggested that Buck's operation, one of the method of treatment of spondylolysis is simple and has low complication rate. We concluded that it is satisfactory to use Buck's operation in young patients with symptomatic spondylolysis.
