We report a case of accidental epidural ephedrine injection. A 29-year-old male with left femoral artery occlusion was scheduled for thromboembolectomy. The operation was performed under epidural anesthesia. During the operation, ephedrine (30 mg/6 ml) was accidentally injected through epidural catheter instead of ropivacaine (45 mg/6 ml). Following the incident, we injected normal saline (10 ml) in the epidural space to dilute the solution. The patient had no complaint but blood pressure rose to 165/115 mmHg transiently. We observed the patient closely in recovery room and no further complication was found. In previous reports, various attempts have been tried to manage such incidents, but no definitive treatment for accidental injection is known. We present this case to remind the importance of confirming the drug everytime before injection.

In diamnionic dichorionic twins, the type of placenta consists of fused and separate types. The expansion of one twin placenta often occurs in the direction of the other implantation site in fused type. Placental development often leads to collision, and the growth of one or both placentas may be hindered, which can cause intrauterine growth restriction (IUGR). We represent a single case of one placental implantation above the another which caused IUFD in one fetus in diamnionic dichorionic twin pregnancy with a brief review of literatures.

PURPOSE: We evaluated the prognostic factors, survivals and patterns of failure of the patients with locally advanced cervical cancer who received radical radiotherapy alone and induction chemotherapy followed by radiotherapy respectively. MATERIALS AND METHODS: Between May 1985 to December 1992, one hundred and sixty three patients with locally advaneed cervical cancer received curative radiotherapy. Patients were divided into two groups: control group included 69 patients who received curative radiotherapy and combined group included 94 patients who received induction chemotherapy followed by curative radiotherapy. The curative radiotherapy consisted of external pelvic radiotherapy and intracavitary brachytherapy. Induction chemotherapy was delivered in VBP (vincristine, bleomycin, cisplatin) and FP (5-FU, cisplatin). Follow up period ranged from 2 months to 99 months with median of 50 months. RESULTS: The overall response rate was 94.2% in the control group and 89.4% in the combined group. The response rate by control group was 66.7% for CR (complete response), 27.5% for PR (partial response), 5.8% for NR (no response). The response rate by combined group of CR, PR, NR were 64.9%, 24.5%, 10.6%, respectively. There was no difference in response for control group and combined group (p> 0.05). The 5-year overall survival had no significant difference in between control group and combined group (54.6% vs. 57.3%). The 5-year disease free survival also had no significant difference (52.9% vs. 55.0%). In the control group, 23 patients (33.3%) had treatment failure: twelve (17.4%) at a local recurrence, 9 (13.0%) as distant metastasis, and 2 (2.9%) with both local recurrence and distant metastasis. In the combined group, Thirty patients (31.9%) failed therapy, with local recurrence in 21 patients (22.3%), distant metastasis in 7 patients (7.5%), and both in 2 patients (2.1%). The difference between the two groups was not significant in view of patterns of failure. The major toxicities were nausea/ vomiting, leukopenia, anemia, and diarrhea. The prognostic factors affecting were hemoglobin level, KPS (karnofsky performance status), and treatment response in both group by multivariate analysis. CONCLUSION: This study did not prove the efficacy of induction chemotherapy followed by radiotherapy in locally advanced cervical cancer.

Betula platyphylla var. japonica (Betulaceae), also known as Asian white birch, is an endemic medicinal tree, the bark of which has been used in Chinese traditional medicine for the treatment of various inflammatory diseases. In our continuing search for bioactive compounds from Korean natural resources, a phytochemical investigation of the bark of B. platyphylla var. japonica led to the isolation of 7-oxo-β-sitosterol (1) and soyacerebroside I (2) from its ethanol extract as main components by liquid chromatography (LC)/mass spectrometry (MS)-based analysis. The structures of isolates were identified by comparison of ¹H and ¹³C nuclear magnetic resonance spectroscopic data and physical data with the previously reported values and LC/MS analyses. To the best of our knowledge, this is the first study to demonstrate that the isolated compounds, 7-oxo-β-sitosterol and soyacerebroside I, were isolated in B. platyphylla var. japonica. We examined the effects of the isolates on the regulation of adipocytes and osteoblast differentiation. These isolates (1 and 2) produced fewer lipid droplets compared to the untreated negative control in Oil Red O staining of the mouse mesenchymal stem cell line without altering the amount of alkaline phosphatase staining. The results demonstrated that both compounds showed marginal inhibitory effects on adipocyte differentiation but did not affect osteoblast differentiation.

This study was carried out to examine the proportion of fatty acids and contents of trans fatty acid in commercial processed foods in Jeon-Buk area. Contents of trans fatty acid in bakery products ranged from 0.2% to 1.0% per 100 g food. Especially garlic bread and pastry contained the highest amount. Popcorns contained trans fatty acid from 0.0% to 13.4%. Among them, instant popcorns for microwave contained the highest amount, while trans fatty acid was hardly detected in popcorns for theater. And trans fatty acid detected in popcorns was mostly in the form of 18 : 1 trans. The content of trans fatty acid in pizza was nearly 0.2%. Amounts of saturated fatty acid and unsaturated fatty acid were similar between each type of pizza and frozen pizza. Fritters such as fried chickens and vegetables contained trans fatty acid less than 0.2% per 100 g food.

Novel agents to treat multiple myeloma (MM) have increased complete respone (CR) rates compared with conventional chemotherapy, and the quality of the response to treatment has been correlated with survival. The purpose of our study was to show how of early response to bortezomib combined chemotherapy influences survival in patients with newly diagnosed MM who are ineligible for stem cell transplantation. We assessed patient responses to at least four cycles of bortezomib using the International Myeloma Working Group response criteria. The endpoints were comparisons of progression free survival (PFS) and overall survival (OS) between early good response group (A group) and poor response group (B group). We retrospectively analyzed data from 129 patients registered by the Korean Multiple Myeloma Working Party, a nationwide registration of MM patients. The 3 yr PFS for the A and B groups was 55.6% and 18.4%, respectively (P < 0.001). The 3 yr OS for the A and B groups was 65.3% and 52.9%, respectively (P = 0.078). The early response to at least four cycle of bortezomib before next chemotherapy may help predict PFS in patients with MM who are ineligible stem cell transplantation.

Purpose:
Breast cancer gene (BRCA) mutation is a well-known risk factor for breast cancer, and clinical interest in prophylactic mastectomy has increased in recent years.We investigated patients who were BRCA mutation carriers and underwent contralateral risk-reducing mastectomy (RRM), focusing on the incidence of occult malignancy after contralateral RRM.
Methods:
Prospectively collected data of patients with breast cancer treated at a single institution were retrospectively reviewed. Patients who underwent RRM with BRCA mutation who underwent RRM between January 2010 and November 2023 were included in this study.Among patients who underwent contralateral RRM, those with a primary cancer diagnosis were included, and those with occult malignancy on the contralateral RRM side were reviewed additionally. The demographics and pathologies of both primary breast cancer and occult malignancies were evaluated.
Results:
In our institution, 925 patients were identified as BRCA mutation carriers, and 320 patients underwent contralateral RRM along with primary breast cancer surgery. BRCA2 mutation occurred more frequently (54.8%) in the overall BRCA mutation cohort. Furthermore, we reviewed 320 patients diagnosed with breast cancer and detected as BRCA mutation carriers who underwent contralateral RRM; high proportion of them were BRCA1 mutation carriers.Interestingly, we found a low incidence of only seven patients (2.2%) with occult malignancy on contralateral RRM side, which is different from that reported in other nations.
Conclusion
The incidence of occult malignancy in the contralateral breast of breast cancer patients with breast cancer with BRCA mutation is significantly low, and may be influenced by several factors. Increased utilization of screening and advancements in diagnostic technologies in South Korea have reduced the chance of occult malignancy in RRM, and a variety of pathologic examination methods may affect the rate of incidence.

BACKGROUND/AIMS: The purpose of this study was to determine the correlations between inflammatory factors-including absolute lymphocyte count, lactate dehydrogenase, beta2-microglobulin, albumin, C-reactive protein, and ferritin-and the prognosis for survival in patients with multiple myeloma (MM) treated with induction chemotherapy containing thalidomide and who underwent autologous stem cell transplantation (ASCT). METHODS: Data from patients at 13 university hospitals in South Korea were collected retrospectively between December 2005 and May 2013. RESULTS: The median age of the 232 patients was 57 years (range, 33 to 77) and the male to female ratio was 1.09:1. In the multivariate analysis, fewer than two combined abnormal inflammatory factors was the only independent prognostic factor for superior progression-free survival (relative risk [RR], 0.618; 95% confidence interval [CI], 0.409 to 0.933; p = 0.022), and platelet count > 100 x 109/L and fewer than two combined abnormal inflammatory factors were independent prognostic factors for superior overall survival (RR, 4.739; 95% CI, 1.897 to 11.839; p = 0.001 and RR, 0.263; 95% CI, 0.113 to 0.612; p = 0.002, respectively). CONCLUSIONS: Patients with two or more than two combined inflammatory factors who were treated with thalidomide induction chemotherapy and who underwent ASCT showed significantly shorter survival compared to those with fewer than two combined inflammatory factors. These results could be helpful for predicting prognosis in patients with MM.
