Although severe hemolytic diseases of the newborn triggered by anti-M are very rare, anti-M alloantibodies have been known to be associated with a cause of multipie intrauterine death. Serological and hematological investigations have been reported on a woman who experienced four multiple intrauterine deaths due to anti-M. The mothers blood type was of group A, NN and the husbands cells were of group B, MN. In the serological examination at 9th week's gestation of the fifth pregnancy, anti-M antibodies were identified in her serum. The antibodies comprised IgM saline agglutinin at a titer of 16 at 4 degrees C and IgG agglutinin reacted in an indirect antiglobulin technique at a titer of 4 at 37 degrees C. She underwent high-dose immunoglobulin infusion therapy on a monthly program from 3rd month gestation and a total of 6 times of intravenous immunoglobulin was given. The anti-M titer did not rise during the pregnancy. She delivered a live girl by cesarean section at the 37th week because of a failure of induction. The childs blood type was of group O, MN. The child was discharged and developed normally.

Primary carcinoma of the fallopian tube is a rare malignancy of the female genital tract and infrequently diagnosed before an operation. The majority of patients have extensive disease at the time of diagnosis. We have experienced incidentally a case of a carcinoma of the fallopian tube coexisting with a benign cystic teratoma of the ovary in a 25-year-old woman. We report this case with a brief review of literatures.

OBJECTIVE: In trauma patients, the distribution of time to death can be used in many ways. We examined the distribution of time to death in trauma patients who expired during a 10-year and analyzed the risk factors of early deaths. METHOD: From January 1994 to December 2003, trauma patients who had been admitted and had expired at tertiary hospitals were enrolled. A retrospective study was done to determine the distribution of trauma mortality and compared the differences between patients who succumbed during the first 5 years and those who succumbed during the second 5 years. We also analyzed the risk factors associated with early deaths that occurred within 6 hours after injury. RESULT: The distribution was bimodal for both the first and the second 5 years. During the second 5 years, there was about two times as many death within 1 hour after injury. The average ages were 36.5 years for the first 5 years and 43.6 years for the second 5 years (p<0.05). The transport times were 35 minutes for the first 5 years and 31.5 minutes for the second 5 years, and the transports by EMS (119) increased from 45.2% to 77.1%. Motor vehicle accidents were the most common mechanism of injury in both periods, but the number was lower in the second 5 years (p<0.05). The most common causes of death were injuries of head and spine and hemorrhages. Risk factor of early deaths were injury of nervous system and chest trauma. CONCLUSION: In our study, the distribution of trauma mortality was bimodal pattern. The trauma system in Korea should be improved to decrease the early and the late peak. To decrease early deaths, it is important to prevent accident, develop EMS for early transport and pre-hospital management, and connect effectively with the trauma center. To decrease late deaths, aggressive resuscitation, suitable antibiotic therapy, and conservative treatment are important.

Background: Non-obstetric surgery during pregnancy is associated with adverse obstetric and fetal outcomes. The aim of this study was to investigate the risk of adverse pregnancy outcomes for women who underwent non-obstetric pelvic surgery during pregnancy compared with that of women that did not undergo surgery. Methods: Study data from women who gave birth in Korea were collected from the Korea National Health Insurance claims database between 2006 and 2016. We identified pregnant women who underwent abdominal non-obstetric pelvic surgery by laparoscopy or laparotomy from the database. Pregnancy outcomes including preterm birth, low birth weight (LBW), cesarean section (C/S), gestational hypertension, gestational diabetes, and postpartum hemorrhage were identified. The adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for the pregnancy outcomes were estimated by multivariate regression models. Results: Data from 4,439,778 women were collected for this study. From 2006–2016, 9,417 women from the initial cohort underwent non-obstetric pelvic surgery (adnexal mass resection, appendectomy) during pregnancy. Multivariate logistic regression analysis indicated that preterm birth (HR, 2.01; 95% CI, 1.81–2.23), LBW (HR, 1.62; 95% CI, 1.46– 1.79), C/S (HR, 1.13; 95% CI, 1.08–1.18), and gestational hypertension (HR, 1.35; 95% CI, 1.18–1.55) were significantly more frequent in women who underwent non-obstetric surgery during pregnancy compared to pregnant women who did not undergo surgery. When the laparoscopic and laparotomy groups were compared for risk of fetal outcomes, the risk of LBW was significantly decreased in laparoscopic adnexal resection during pregnancy compared to laparotomy (odds ratio, 0.62; 95% CI, 0.40–0.95). Conclusion Non-obstetric pelvic surgery during pregnancy was associated with a higher risk of preterm birth, LBW, gestational hypertension, placenta previa, placental abruption, and C/S. Although the benefits and safety of laparoscopy during pregnancy appear similar to those of laparotomy in regard to pregnancy outcomes, laparoscopic adnexal mass resection was associated with a lower risk of LBW.

OBJECTIVE: The aim of this investigation was to analyze the association between a single nucleotide polymorphism (SNP) in L-myc gene (T3109G) and the cervical cancer susceptibility or invasiveness in Korean women. METHODS: The blood samples of 231 cervical cancer patients and 332 non-cancer control subjects who managed at Seoul National University Hospital from 1999 to 2002 were collected. Polymorphism in L-myc (T3109G) was determined using TaqMan method. Allele frequency and genotype distribution in the cervical cancer group were compared with those of the control group to determine whether this polymorphism elevates the susceptibility of Korean women to the cervical cancer. The relationship between this SNP and cancer invasiveness was also evaluated by collating clinicopathologic data of those in the cancer group, such as age, FIGO stage, histologic type, lymph node metastasis and parametrial invasion. RESULTS: In the cervical cancer group, the allele frequency of G was 47.6%, in the control group 48.5%, showing no significant difference (p=0.808). Similarly the genotypes with TG or GG showed no increased risk for the cervical cancer compared with TT genotype. A subgroup analysis of the clinicopathologic parameters in cancer group also showed no significant difference suggesting the lack of an association between SNP of the L-myc and the cervical cancer invasiveness. CONCLUSION: This study shows that Korean women with specific polymorphism in L-myc are neither more susceptible to develop the cervical cancer nor more vulnerable for the cancer progression.

PURPOSE: Recently, cholangioscopy using narrow band imaging (NBI) has been used as a diagnostic modality for better visualization in hepatobiliary malignancies; however, there are few reports on it. Our aim is to evaluate the effectiveness of cholangioscopy using NBI in hepatobiliary malignancies. METHODS: Between January 2007 and December 2016, 152 cholangioscopies using percutaneous approach were conducted in total 123 patients. Among these, 36 patients were suspicious of hepatobiliary malignancies. Thirteen patients with an ambiguous margin on endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography (MRCP), for whom NBI tipped the balance in diagnosis of lesion and decision of lesion extent by adding NBI, were involved in our study. RESULTS: Underlying diseases were all malignant in 13 patients (11 bile duct cancers, 1 liver cancer, 1 pancreas cancer with common bile duct invasion). In 7 cases with papillary type tumor, minute superficial spreading tumor was detected by NBI more easily, and NBI provided a better visualization of tumor vessel and margin evaluation in 4 cases with infiltrative tumor. In 2 cases with mucin-hypersecreting tumor, NBI showed better penetration through the mucin and gave us a much clearer image. Nine patients ultimately underwent surgical resection. The margins predicted by NBI cholangioscopy were consistent with the pathological margins on the resected specimens. CONCLUSION: In conclusion, cholangioscopy using NBI is very useful for evaluation of suspected hepatobiliary malignancies with an ambiguous margin on ERCP or MRCP. It can give us an accurate pathologic mapping, and this information seems to be essential before deciding on a treatment strategy.

Objective: Emergency department (ED) overcrowding is a global issue that negatively impacts the clinical outcome. Through the coronavirus disease 2019 (COVID-19) pandemic era, overcrowding of ED isolated territory (isolation bed) was aggravated. This study analyzed overcrowding indices of ED isolation beds during the COVID-19 pandemic. Methods: This study was a single-center, retrospective, observational study. The study analyzed 34,925 patients who visited the ED during the COVID-19 pandemic from April 2021 to August 2022. Patients who were treated in isolation beds and regular beds were compared. Among the patients using isolation beds, patients who stayed longer than 720 minutes were also classified and analyzed. Results: During the analysis period, 4,479 and 34,943 patients were treated in the ED isolation bed and ED regular bed, respectively. The overcrowding indices (general ward admission rate, intensive care unit admission rate, ED-length of stay, transfer rate, mortality rate, prolonged ED stay patient ratio) of the isolation beds were significantly higher than those of the ED regular bed (P<0.05). The prolonged ED stay-patient ratio of isolation beds and regular beds was affected by the number of COVID-19 patients (regular bed, r=0.617 and P=0.01; isolation bed, r=0.525 and P=0.03). The average ED-length of stay of isolation beds was longer than that of the ED regular beds. One hundred and forty-five patients were classified as prolonged ED stay patients. Their time from the decision point to the discharge point comprised a higher rate with an average of 76.52%. Conclusion ED isolation beds are more vulnerable to infectious disease outbreaks. A proper medical policy and arrangement management system that can flexibly deal with disaster emergencies are required

Multiple endocrine neoplasia (MEN) is a combination of endocrine tumor associations and consists of 3 types: 1, 2A and 2B. Herein, we report a case of insulinoma which is combined with pheochromocytoma discovered at the left adrenal gland which was treated by surgical resection. We think there is a possibility of a new type of multiple endocrine neoplasia (MEN).

OBJECTIVE: The aim of this investigation was to analyze the association between a single nucleotide polymorphism (SNP) in L-myc gene (T3109G) and ovarian cancer risk or prognosis in Korean women. METHODS: The blood samples of 98 ovarian cancer patients and 332 non-cancer control subjects who managed at Seoul National University Hospital from 1999 to 2002 were collected. Polymorphism in L-myc (T3109G) was determined using TaqMan method. Allele frequency and genotype distribution in the ovarian cancer group were compared with those of the control group to determine whether this polymorphism elevates the susceptibility of Korean women to ovarian cancer. The relationship between this SNP and cancer invasiveness or prognosis were also evaluated by collating clinicopathologic data of those in the cancer group, such as surgical stage, stromal invasion, histologic type, and survival. RESULTS: In the ovarian cancer group, the allele frequency of G was 51.0%, in the control group 48.5%, showing no significant difference (p=0.569). Similarly the genotypes with TG or GG showed no increased risk for ovarian cancer susceptibility compared with TT genotype. A subgroup analysis of the clinicopathologic parameters in cancer group also showed no significant difference suggesting the lack of an association between SNP of the L-myc and ovarian cancer invasiveness and survival. CONCLUSION: This study shows that Korean women with specific polymorphism in L-myc are neither more susceptible to develop ovarian cancer nor more vulnerable for cancer progression.
