PURPOSE: The annual incidence of breast neoplasms continues to rise, but only a few studies on the risk factors for breast neoplasms in Korea have been conducted. The aim of this study was to analyze the risk factors of breast neoplasms in Korean women using a case-control study. METHODS: The participants in the study were 131 women diagnosed with breast neoplasms at the Department of Surgery, Chonbuk National University Hospital between April 1999 and March 2002. Individually age matched cases were used as the control group. A conditional logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (95% CI). RESULTS: The mean age of the patients was 45.0 years, with 50.38% between 40 and 49 years. After adjustment for potential confounders, a positive family history of breast cancer and breast pain were associated with an increased risk of breast neoplasms (OR=4.916, 95% CI=1.055~22.913; OR=4.308, 95% CI=2.179~8.514). A regular breast examination was associated with breast neoplasms incidience (OR=3.543, 95% CI=1.860~6.751). However, other factors including reproductive factors, were found to exhibit no significant association with breast neoplasms. CONCLUSION: The present study suggests a family history of breast neoplasms, breast pain and a regular breast examination was associated with breast neoplasms incidence in Korean women.

PURPOSE: Incidental resection of parathyroid gland is not uncommon during thyroid surgery and may occur even in experienced thyroid surgeons. The aim of this study was to investigate the incidence, risk factors, and clinical relevance of incidental parathyroidectomy during thyroid surgery. METHODS: A retrospective review of patients who underwent thyroid surgery between January and December 2008 was carried out. Pathologic reports were reviewed for the presence of parathyroid tissue in resected thyroid specimen. Two groups of patients were studied: a group with incidental parathyroidectomy (Group A) and without incidental parathyroidectomy (Group B). RESULTS: Three hundred and thirty-four thyroid surgery were performed: 194 total thyroidectomies, 18 near- or subtotal thyroidectomies, 44 lobectomies, 23 endoscopic total thyroidectomies, 55 endoscopic lobectomies. Of these, 265 patients (79.3%) were preformed for malignant disease. Incidental parathyroidectomy occurred in 30.5% (102/334) of thyroid surgery. Risk factors for incidental parathyroidectomy included malignant pathology (P<0.001), operation method (P<0.001), lymph node dissection (P<0.001), and extrathyroidal invasion (P=0.001). Biochemical hypocalcemia was defined as a serum calcium levels less than 8.4 mg/dL. Symptomatic hypocalcemia was defined as patient had tingled sense or spasm of muscle and need to add more calcium replacement. In group A, 86 patients (93.5%) had a biochemical hypocalcemia (P=0.001). Symptomatic hypocalcemia developed in 35.3% (36/102) of group A, compared to 20.7% (48/232) in group B (P=0.005). CONCLUSION: Malignant pathology, total thyroidectomy, lymph node dissection, and extrathyroidal invasion were associated with a significantly higher risk of incidental parathyroidectomy during thyroid surgery. Incidental parathyroidectomy resulted in biochemical and symptomatic postoperative hypocalcemia. This study suggests that incidental parathyroidectomy may be a potential complication; therefore, parathyroid glands should be identified and preserved with more meticulous inspection during thyroid surgery.

Although the incidence of extrapyramidal reactions associated with metoclopramide has been reported to be approximately 0.2%, such reactions are rare in the anesthetic field. Several anesthetic adjuvants, including ondansetron and pregabalin, have also been associated with extrapyramidal side effect. Here, the authors report the case of a 47-year-old patient, previously administered pregabalin and ondansetron, who developed extrapyramidal side effects after a single injection of metoclopramide (10 mg) in a post-anesthesia care unit.

Ibandronate (a bisphosphonate) is commonly used as an treatment of osteoporosis in combination with vitamin D. Monthly DP-R206-a novel, fixed-dose combination tablet (150 mg ibandronate/24,000 IU vitamin D3)-was recently developed to enhance patient compliance. This open, randomized, two-period crossover study was conducted to compare the pharmacokinetics of ibandronate when administered as DP-R206 or 150 mg ibandronate to healthy adult volunteers. Each volunteer was randomly allocated to receive single-dose DP-R206 or ibandronate with a 28-day washout period between treatments. Blood samples were assessed using pharmacokinetic analysis. Plasma ibandronate concentrations were determined using liquid chromatography-tandem mass spectrometry. Safety and tolerability assessments were performed throughout the study. In total, 103 participants received the study drugs and 72 participants completed the study. The geometric mean ratios (DP-R206/ibandronate) of the maximum concentration (C(max)) and the area under the plasma concentration time curve from time zero to the last concentration (AUC(last)) values were 0.959 (90% CI: 0.820-1.120) and 0.924 (90% CI: 0.805-1.060), respectively. The frequencies of adverse events (AEs) and drug reactions were similar between treatment groups, and all AEs were recovered without sequalae. Ibandronate pharmacokinetics, tolerability, and safety are comparable when administered to healthy individuals, regardless if administered as DP-R206 or ibandronate.

PURPOSE: Tetanus is difficult for emergency physician to diagnosis at an early stage because of its low incidence and atypical initial clinical features. Therefore, we reviewed the clinical features of 54 tetanus cases and attempted to identify factors associated with prognosis in order to improve early diagnosis and treatment. METHODS: We carried out a retrospective chart review of 54 adult tetanus patients who presented to the ED of Chonnam National University Hospital between January 1996 and December 2005. We collected information on demographics, SAPS II score, clinical feature, course of infection and prognosis. We divided the patients to two groups according to the survival and compared their data statistically. RESULTS: Fifty four patients, 33 men and 21 women, were included in the study. The mean age was 50.97+/-15.95. The most common initial diagnosis in ED were electrolyte imbalance (n=15), neck and facial dystonia (n=9). The mean incubation period was 10.27+/-6.47 days. The initial SPAS II score 17.29+/-8.45 and the Wood score was 3.12 +/-1.47. Most commonly symptom was dyspnea and dysarthria. Twenty one patients were supported by mechanical ventilation, and the duration of mechanical ventilation was 5.92+/-4.52 days. On multivariate logistic regression analysis, four variables were found to be associated with the prognosis: incubation period, Wood score, Time interval from initial symptom to mechanical ventilation, initial SAPS II. CONCLUSION: Four variables correlated well with the prognosis: Incubation period, Wood score, Time interval from initial symptom to mechanical ventilation, initial SAPS II score.

BACKGROUND: Different tidal volume (TV) settings during mechanical ventilation alter intrathoracic blood volume, and these changes could alter central venous pressure and the cross sectional area (CSA) of the right internal jugular vein (RIJV). The aim of this study was to determine the optimal TV for maximizing the CSA of the RIJV in the supine and Trendelenburg positions in anesthetized patients. METHODS: Forty patients were randomly allocated to a supine group (Group S, n = 20) or a Trendelenburg group (Group T, n = 20) by computer generated randomization. RIJV CSAs were measured repeatedly after increasing the inspiratory volume in 1 ml/kg increments from a TV of 8 ml/kg to 14 ml/kg using ultrasound images. RESULTS: Peak inspiratory pressure increased significantly on increasing TV from 11 ml/kg to 14 ml/kg and between baseline (TV 8 ml/kg) and 11 ml/kg in both groups (P < 0.05). RIJV CSA was not increased versus baseline even after TV changes in either group and no intergroup difference was found. CONCLUSIONS: TV increases do not increase the CSA of the RIJV within the TV range 8 to 14 ml/kg in the supine or 10degrees Trendelenburg position.

This study was undertaken to investigate the change of ear swelling response (ESR) of the mice according to repetitive ultraviolet radiation. 100mJ/crn of UVB was irradiated daily for 4 weeks, and a total of 25 C57BL mice were used as subjects. The results were as follows : 1. After 1 day, 2 days and 3 days irradiation of UVB, ESR reached 21.3+/-1.5, 22.3+/-1.1 and 24.3+/-1.6 respectively with increasing tendency, but there was no statistical significance (Wilcoxon rank sum test p>0.05). 2. ESR reached at maximum, 78.0+/-1.8, after 1 week(p<0.01), thereafter ESR decreased gradually with reparative process. 3. Inspite of continued irradiation, ESR decreased gradually after 2 weeks. After 2 weeks, 3 weeks and 4 weeks irradiation, ESR decreased to 51.6+/-11.8, 45.1+/- 3.3 and 42.8+/-6.8 respectively, but, there were still increment of ESR (p<0.01).

A 70-year-old woman with an infectious thrombus in her left internal jugular vein (IJV) underwent carotid endarterectomy for stenosis and a highly movable plaque in her right carotid artery. She had been treated with antibiotics for four weeks before surgery due to Lemierre syndrome, a rare septic thrombophlebitis in the IJV secondary to an oropharyngeal infection. The right IJV was in a two-fold dilated state due to compensation for a thrombotic left IJV. Accordingly, superficial cervical plexus block was performed under ultrasound guidance to ensure safety and accuracy. During surgery, the alertness was maintained and the patient did not complain of pain in the absence of additional analgesics. No block-related complications were encountered. The authors report for the first time their regional anesthetic experiences in a patient with Lemierre syndrome.
