Malignant tumor is found in 1-2% of ovarian benign cystic teratomas. Among these malignant neoplasms, squamous cell carcinoma is by far the most common malignancy, whereas the incidence of struma ovarii is less than 5% in mature teratoma. As far as concerned the struma ovarii, a very small percentage is associated with carcinoid, mucinous or serous cystadenoma, or Brenner tumor. However, any reports of struma ovarii associated with squamous cell carcinoma in the same ovary could not be found in English literature. Recently we have experienced a case of squamous cell carcinoma and struma ovarii arising in an ovarian benign cystic teratoma in 72 year old female patient.

PURPOSE: The purpose of this study was to investigate the effect of aromatherapy on pain, depression, and feelings of satisfaction in life of arthritis patients. METHOD: This study used a quasi-experimental design with a non-equivalent control group, pre-and post-test. The sample consisted of 40 patients, enrolled in the Rheumatics Center, Kangnam St. Mary's Hospital, South Korea. The essential oils used were lavender, marjoram, eucalyptus, rosemary, and peppermint blended in proportions of 2:1:2:1:1. They were mixed with a carrier oil composed of almond (45%), apricot(45%), and jojoba oil(10%) and they were diluted to 1.5% after blending. The data were analyzed using an 2-test, Fisher's exact test, t-test and paired t-test. RESULT: Aromatherapy significantly decreased both the pain score and the depression score of the experimental group compared with the control group. However, aromatherapy didn't increase the feeling of satisfaction in life of the experimental group compared with the control group. CONCLUSION: The result of this study clearly shows that aromatherapy has major effects on decreasing pain and depression levels. Based on our experiment's findings, we suggest that aromatherapy can be a useful nursing intervention for arthritis patients.

The alterations in the localization of keratinocyte membrane glycoconjugates in allergic contact dermatitis were investigated in guinea pig skin treated with topical application of 2.4-dinitro-chlorobenzene. We employed the avidin-biotin complex(ABC) method for the detection of localization of 10 commercially available lectins labelled with biotin: Con-A, SBA, WGA, DBA, UEA-1, RCA-1, PNA, HP, MPA, and ECA. Staining with WGA showed a remarkably decreased intensity in basal and spinous layers of the allergic skin in comparison to those of the control skin, suggesting loss of terminal sialic acids in cell membrane glycoconjugates. The other lectins showed no remarkable difference in the staining patterns between the normal and the allergic ski. The results suggest that epidermal cell membrane glycoconjugates undergoes selective perturbations in acute allergic contact dermatitis, and that the keratinocytes might be an active part of the cutaneous immune system.

PURPOSE: There have been conflicting reports on vascular response to Panax ginseng. The conflicting reports may be due to difference of ingredient of Panax ginseng. The aim of the present study was to investigate the effect of saponin, the main ingredient of Panax ginseng, on the vascular contractility. METHODS: The rabbit aortic rings were cut and mounted on the force transducer to record an isometric tension on polygraph. To elucidate the mechanism of saponin effect on vascular smooth muscle, the contractility of the vascular smooth muscle were measured under varying experimental condition. RESULTS: 1) When the aortic rings were precontracted with norepinephrine, saponin caused biphasic(initial relaxation-sustained contraction) dose-response in the endothelium dependent manner. But saponin had no effect on the resting tension. 2) When EDRF inhibitors such as methylene blue(10(-5)M), hemoglobin(10(-5)M), N-omega-nitro-L-arginine(100microM) were added to precontracted ring with norepinephrine, the initial relaxation caused by 2mg% saponin was inhibited. 3) When Ca(2+)-channel blocker, nifedipine(5x10(-7)M), was added to precontracted rings with norepinephrine, the sustsined contraction by saponin was inhibited. 4) When hemoglobin(10(-5)M) was added to precontracted rings with norepinephrine, the contractility by norepinephrine was increased and this effect was further augmented by 2mg% saponin. CONCLUSIONS: From the above results, it may be concluded that saponin stimulated the release of both an endothelium-dependent relaxing factor and endothelium-dependent contracting factor.

BACKGROUND: It has been found that parental role is essential for obesity management in childhood. However, there are few studies concerning parental perception on childhood obesity in Korea. Parental perception on childhood obesity according to weight status in elementary school children was examined. METHODS: The subjects were 3,996 elementary school children and their parents in Busan. The surveys which included socioeconomic characteristics, children's eating habits and activities, parental weight and height, parental perception on childhood obesity, were filled out by parents. Children's body mass index (BMI) were calculated using the height and weight measured in school children were classified into the obese group (BMI 95 Percentile) , the high risk group (85 percentile BMI <95 percentile) and the normal weight group (85 percentile) according to BMI gender and age. The analyses were done using x2_ test and ANOVA. RESULTS: Parental BMI in the obese group was higher than the normal weight group in boys a girls (P<0.001) . Participation in regular exercise was higher among the obese group compared to the normal weight group regardless of sex, but daily exercise time was lesser among the obese group only in boys (P <0.001) . Daily TV watching time was not different according to weight status in both sex. The parents with obese children perceived their children's weight as an appearance problem or a health problem about 7-18 times more likely than the parents of children with normal weight. 70% of obese children have tried weight control. The proportion of parental understanding on childhood obesity as a disease was not different among boys, but different among girls (P<0.001) . Eighty five percents of the parents perceived childhood obesity as a disease or a risk factor. But, their perception for the association of hypertension, fatty liver, sleep apnea syndrome with obesity was relative low. CONCLUSION: Most parents with obese children perceived childhood obesity as an appearance problem, a health problem and as a disease or a risk factor.

Purpose: Microinvasive breast cancer (MIBC) is an invasive carcinoma with a tumor dimension not exceeding 1 mm. Owing to its low incidence, the rate of axillary node metastasis and its management are not well established. The aim of this study was to assess the incidence of lymph node metastasis (LNM) and identify variables associated with LNM, as well as to evaluate the need for axillary staging in MIBC patients by analyzing nationwide data. Methods: The Korean Breast Cancer Society registry was searched to identify MIBC patients diagnosed between January 1996 and April 2020. Patients without neoadjuvant chemotherapy experiences, systemic metastasis, and missing or discordant data were eligible for the analysis. The incidence rate of LNM was determined, and variables associated with LNM were identified by multivariable regression analysis. Results: Of 2,427 MIBC patients identified, 98 (4.0%) had LNM and 12 (0.5%) had N2/3 disease. Type of breast operation (odds ratio [OR], 2.093; 95% confidence interval [CI], 1.332–3.290; P = 0.001), age (OR, 2.091; 95% CI, 1.326–3.298; P = 0.002), hormone receptor status (OR, 2.220; 95% CI, 1.372–3.594; P = 0.001), and lymphovascular invasion (OR, 11.143; 95% CI, 6.354–19.540; P < 0.001) were significantly related to LNM. Conclusion The incidence of LNM in MIBC patients was only 4.0% in our study, suggesting that de-escalation of axillary surgical interventions could be carefully considered. The indications for axillary staging should be individualized considering tumor volume, age, hormone receptor status, and lymphovascular invasion to improve the quality of life of MIBC survivors.

For many years, the histogenesis of the granular cell tumor was controversial and this resulted in the tumor being given more than 20 synonyms. Abrikossoff, reporting on the fiist granular cell tomor, favored a muscle origin, but other authora have postulated a fibroblastic or a histiocytic origin. Recently, the concept of Schwann cell origin, supported by electron microscopic studies and immunohistochemistry of S-100 protein, has gained wider recognition. Approximately 90 cases of esophageal granular cell tumor have been reported in the literature, representing about 2% incidence of all reported granular cell tumor, In Korea, only four cases of granular cell tumors were reported in the literatures including the cases occuring in the cecum, colon, and anus until now. Recently we experienced 46-years old women with granular cell tumor of the esophagus, which might be the second case in Korean literature.

PURPOSE: The purpose of this study was to evaluate the timing of sexual maturation and secular trends of menarchial age in Korean adolescents. METHODS: Nine hundred eighty two school students and 119 university female students were included. Tanner's pubertal assessment method was applied using a self-assessment sheet with pictures for their developmental stages. A medical checkup database from 1,156,022 women was also used to analyze the age of menarche from the year 1900 to 1980. RESULTS: Onset of puberty was at 11.3+/-1.3 years(y) in girls and 12.1+/-1.5 y in boys and total pubertal duration was 3.6 y in girls and 3.3 y in boys. Height at the onset of puberty was 146.1+/-7.9 cm in girls and 152.7+/-9.8 cm in boys. Weight at the onset of puberty was 39.3+/-6.9 kg in girls and 47.7+/-14.4 kg in boys. The mean age of menarche was 12.0+/-1.0 y and mean age at nocturnal emission was 12.3+/-1.8 y. By age ten, 3.0 percent of girls experienced menarche, which increased to 41.1 percent by age 12, and 98.0 percent by age over 15. By SMR 2 breast stage, 18.2 percent of girls experienced menarche, which increased to 66.1 percent and 91.7 percent by SMR stages 3 and 4, respectively. By SMR 2 pubic hair stage, 52.0 percent and by SMR 3, 93.8 percent of girls experienced menarche. While the menarchial age of women born around 1980 was 12.4+/-1.1 y, the menarchial age of women born around 1990 was 12.0+/-1.1 y. Age at menarche has been advanced approximately by 2 years between 1900 and 1980 birth cohorts. CONCLUSION: There was a downward secular trend in pubertal timing. Age at menarche has been advanced by 2 years during the last 80 years. Further large scale, prospective studies, including inspection by specialists, are needed to provide reference data for pubertal timing in Korean adolescents.
