OBJECTIVE: We analyzed the clinical features of amniotic fluid embolism confirmed by autopsy or clinical dicision for making a plan of rapid diagnosis and intensive emergency care. STUDY DESIGN: We experienced 2 clincal cases in Ewha Mokdong Hospital and Severance Hospital at 1995, and reviewed the medical record & autopsy report of 15 cases in National Institute of Scientific Investigation from Jan, 1991 to Dec, 1995. RESULTS: The mean maternal age was 31+/-3 years. The mean gestational age was 40+/-1 weeks. The number of delivery were 1.4+/-0.8. The number of abortion history. were 2.6+/-2. The sexuality of fetus were six males (35 %), five females (29%), and unknown six cases (35 %) and the fetal mortality rate was 29 % (5 cases). The initial clinical symptoms and signs were hypotension (12 patients, 71%), vaginal bleeding(ll patients, 65%), cardiac arrest (6 patients, 35 %), dyspnea (5 patients, 29 %), and seizure (2 patients, 12%). In the case of normal spontaneous vaginal delivary (NSVD), the symptoms occurred during induction in 3 (18%), during delivery in 1 (6%), and after delivery in 9 (53%). In the case of Cesarean section, the symptoms occurred during section in 2 (12%), and after section in 1 (6%). There are one case whose symptoms occurred during 3rd gestational period. CONCLUSIONS: We should alert for the amniotic fluid embolism in the clinical findings of acute collapse and vaginal bleeding, respiratory symptoms, and seizure at any peripartum. With eary suspicion of this disease and aggressive intensive care we can reduce amniotic fluid embolism mortality rate and it's legal problem.

The severe form of chronic periodontitis(CP) has been reported to be strongly associated with the presence of allele 2 of composite IL-1B(+3954) and IL-1A(+4845) genetic polymor- phisms(genotype positive). However, other studies have reported conflicting findings. These might have resulted from differences in ethnic background and disease entities. The aim of this study was to determine the distribution of IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN(VNTR) genetic polymorphisms in children as a future Korean population. The study population consisted of 92 children from the Dept. of Pediatric Den- tistry, Chonnam National University Hospital. Genomic DNA was obtained from buccal swab. The IL-1A(+4845), IL-1B(+3954), and IL-1B(-511) genes were genotyped by amplifying the polymorphic region using multiplex polymerase chain reaction(PCR), followed by restriction enzyme digestion and gel electrophoresis. IL-1 RN(VNTR) polymorphism were then evaluat- ed by PCR amplification and fragment size analysis in agarose gel. The allele 2 frequency was 41.3%, 4.3%, 47.8%, and 9.9% for IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN respectively. The frequency of genotype with allele 2 carriage for IL-1A(+4845), IL-1B(+3954), IL-1B(-511), and IL-1 RN was 77.1%, 7.6%, 63.0%, and 15.2% respectively. The allele 2 frequency in IL-1B(+3954) was significantly higher in female than in male population(p<0.05). The negative association was shown between the presence of allele 2 in IL-1B(-511) and in IL-1B(+3954), and the carriage rate of IL-1B(+3954) allele 2 tended to lower in IL-1B(-511) allele 2(P=0.056). Only 7.3% of children carried the composite genotype of IL-1A(+4845) and IL-1B(+3954). These results suggest that the polymorphism of IL-1B(+3954) and the positive composite genotype was relatively rare in Korean population.

4.International regulatory considerations pertaining to the development of stem cell-based veterinary medicinal products

Journal of Veterinary Science 2021;22(1):e6-
Stem cell-based products (SCPs) are an emerging field of veterinary medicine that focuses on the regeneration, repair, or replacement of damaged tissues or organs. However, there are some issues in applying the traditional regulatory guideline for the approval of SCPs as veterinary medicinal products. This article describes the positions of Korea, US, and EU regarding SCPs, and compares the regulatory guidelines of each country for their safety evaluation. Although there are some differences in the regulatory guidelines, similar considerations in identifying the quality of SCPs and their safety has adopted. Overall, these guidelines need to be harmonized among countries.

PURPOSE: This study aimed was done to analyze recent trends in nursing research published in the Journal of Korean Academy of Nursing by focusing on the content of nursing interventions and their level of evidence. METHODS: A total of 209 studies published between 2007 and 2008 were reviewed using analysis criteria developed by the researchers. RESULTS: The number of quantitative studies was greater than that of qualitative studies. There was a slight increase in the number of qualitative studies and studies including elderly populations, which reflects the recent population trend in Korea. More randomized controlled trials with a low risk of bias were needed to support more evidence-based nursing practice. Concerning the low rate of ethical consideration, stricter application of research ethics needs to be encouraged. CONCLUSION: The findings of this study suggest the recent trends in nursing research and the direction of nursing research and review in the Journal.

OBJECTIVE: To determine the prognostic factors for local recurrence of nodular hepatocellular carcinoma after segmental transarterial chemoembolization. MATERIALS AND METHODS: Seventy-four nodular hepatocellular carcinoma tumors < or = 5 cm were retrospectively analyzed for local recurrence after segmental transarterial chemoembolization using follow-up CT images (median follow-up of 17 months, 4-77 months in range). The tumors were divided into four groups (IA, IB, IIA, and IIB) according to whether the one-month follow-up CT imaging, after segmental transarterial chemoembolization, showed homogeneous (Group I) or inhomogeneous (Group II) iodized oil accumulation, or whether the tumors were located within the liver segment (Group A) or in a segmental border zone (Group B). Comparison of tumor characteristics between Group IA and the other three groups was performed using the chi-square test. Local recurrence rates were compared among the groups using the Kaplan-Meier estimation and log rank test. RESULTS: Local tumor recurrence occurred in 19 hepatocellular carcinoma tumors (25.7%). There were: 28, 18, 17, and 11 tumors in Group IA, IB, IIA, and IIB, respectively. One of 28 (3.6%) tumors in Group IA, and 18 of 46 (39.1%) tumors in the other three groups showed local recurrence. Comparisons between Group IA and the other three groups showed that the tumor characteristics were similar. One-, two-, and three-year estimated local recurrence rates in Group IA were 0%, 11.1%, and 11.1%, respectively. The difference between Group IA and the other three groups was statistically significant (p = 0.000). CONCLUSION: An acceptably low rate of local recurrence was observed for small or intermediate nodular tumors located within the liver segment with homogeneous iodized oil accumulation.

Rhabdomyosarcoma originating from the chest wall is a rare malignant tumor in children and was considered to be guarded in prognosis previously. However, recent advances in multidisciplinary treatment of rhabdomyosarcoma in children have improved the disease free survival rate. Authors report a case of alveolar rhabdomyosarcoma, stage III, originating from the chest wall who is surviving free of disease for 15 months with aggressive chemotherapy and radiotherapy.

Myxoid neurofibroma is a benign tumor of perineural cell origin, which is demonstrated with a positive immunohistochemical stainig for S-100. The most common locations of the myxoid neurofibroma are face, shoulder, arm, periungual and foot. We experienced an unusual case of myxoid neurofibroma which originated from labia majora area then reported it. To our knowledge, this is the first time that a labia majora location is reported.
