Infantile fibrosarcoma is a rare malignant soft tissue tumor occurring especially in newborn and young children under 2 years. We experienced three cases of infantile fibrosarcoma presenting in the neonatal period. Case 1 presented with a multiseptated cystic mass on his left thigh at birth that was diagnosed as lymphangioma. After picibanil injection, we noted the size of the mass doubled and a solid lesion was prominent in the magnetic resonance image. Case 2 was found to have a reddish mass on his lower back mimicking hemangioma. Over 2 weeks, the mass grew rapidly with internal hemorrhaging. Case 3 was noted to have an encircling mass around the splenic flexure, which developed into congenital bowel obstruction. All of the tumors were resected completely, but microscopic resection margin was not clear in two patients. The two patients received adjuvant chemotherapy and all patients are well without evidence of recurrence.

A case of clear cell adenocarcinoma arising in the female urinary bladder, which is accompanied by endometriosis of the urinary bladder and the uterus, is reported. The carcinoma protruded into the vesical lumen as a fungating mass, and had a tubulocyotic pattern. The tumor cell had intracytoplasmic glycogen and electron microscopically short microvilli on their surface, resembling clear cell acenocarcinoma of the female genital tract including ovary. This is the fourth case report of clear cell adenocarcinoma complicating vesical endometriosis, and may support the view that clear cell carcinome arises from endometriosis which, in turn, from the Mullerian remnant.

We report a case of solitary congenital calcified nodule of the ear in a 1-year-old female. The lesion was a 2 X 2mm-sized, elevated, slightly erythematous and whitish-centered nodule located since birth on the superior helical rim of her left ear. Histopathological findings fram the totally excised lesion showed calcium deposits as amorphous, basophilic masses in the upper dermis and focal discharge of calcium by means of transepidermal elimination. Surrounding the calcium deposits, lymphohistiocytic infiltrations were present.

PURPOSE: This study aimed to compare the quality of nursing care as perceived by registered nurses and mothers of hospitalized children in South Korea. METHODS: This was a descriptive study that recruited 70 mothers of hospitalized children and 70 nurses in pediatric units in university hospitals as participants. The quality of pediatric nursing care was measured using importance and performance scores for 19 items describing various elements of nursing care. The collected data were analyzed using descriptive statistics and the independent t-test. RESULTS: The hospitalized children mothers' mean importance scores were significantly higher than those of the nurses (t=2.94, p=.004). However, there were no significant differences in the mean performance scores of nurses and mothers (t=0.91, p=.363) or between nurses' and mothers' perceptions of quality of nursing care, with the exception of a significant difference for the quality of explanations (t=2.78, p=.006). The quality of explanations was assessed more positively by nurses than by mothers. CONCLUSION: This study suggests that when developing strategies to improve the quality of nursing care in pediatric wards, ensuring that pediatric nurses provide detailed explanations should be considered as a way to improve the quality of nursing care in pediatric units.

Objectives:
The purpose of this study was to identify the effectiveness of COVID-19 vaccinations on deaths of the COVID-19 cases in some elderly long-term care facilities (LTCF) in Gwangju Metropolitan City.
Methods:
The study subjects were 659 COVID-19 cases in residents of 7 elderly LTCF, Gwangju, from 21 Dec. 2021 to 28 Jan. 2022. The used variables were confirmed dates for COVID-19, demographic characteristics, co-morbidities, presentation of symptoms, death and vaccination related characteristics including type of vaccine, doses and dates. Vaccination status were classified as not vaccinated, partially and fully vaccinated. The associations of vaccination status and deaths of COVID-19 cases were tested by chi-square test and multiple logistic regression analysis.
Results:
The rates of not vaccinated, partially vaccinated and fully vaccinated were 19.4%, 10.2% and 70.4%, respectively. The mortality rate of the cases was 6.4%.The death rate by vaccination status was 16.4% in not vaccinated, 15.4% in partially vaccinated and 2.6% in fully vaccinated, showing a statistically significant difference. The adjusted odds ratios (ORs) (95% confidence intervals, CIs) of death compared to fully vaccinated were 7.64 (3.87-16.34) in non-vaccinated, and 6.97 (3.44-14.14) in partially vaccinated.
Conclusions
COVID-19 vaccination seems to work effectively in preventing deaths of COVID-19 cases of elderly LTCF residents. This finding support that fully vaccinations in high risk group such as elderly LTCF residents is very important for one of strategies of COVID-19 management.

Among the diverse factors causing obesity, the life styles and the food habits are very important. This study has carried out to evaluate the association between the habit of living and the Body Composition in 132 male and 313 female of 20-75 years old people in Incheon. The research tools are questionnaires of 6 items of life styles(Smoking, Drinking, Frequency of exercises, Normal Activity Degree, Favorite food, Degree of salt ingestion) and a height and Body Composition. The statistical results are as follows : 38% of male and 23% of female were over the normal range(Korean Society of Obesity 2004). Although the tendency of average BMI are increasing, there was no significant difference in comparison of the average BMI according to the age in male. But, the percentage of Body Fat, the Visceral Fat Area and the WHR, there was statistical significance according to age in male. The middle aged group(between 40~50 years) and older group(over 60 years) were over the normal range. In female, there were significant difference in comparison of the average BMI, the percentage of Body Fat, the WHR, the Visceral Fat Area and the Fitness Score. Especially, in the old female group, the BMI and the WHR score were over the normal range. The BMI: There was positive correlation with the Percent Body Fat(r=0.796, r=0.839, p=0.000), the Body Fat Mass(r= 0.891, r=0.932, p=0.000) and the WHR(r=0.783, r=0.902, p=0.000). Frequency of Exercises, Normal activity Degree, Favorite food, Degree of salt ingestion : There was significant difference in comparison of sex(P<0.05). The results of this study hope to provide an opportunity to further examine the relationship of the Healthy Behavior to Body Composition and obesity.

Recently, through the development of the primer extension preamplification(PEP) method which amplifies the whole genome, simultaneous multiple DNA analysis has become possible. Whole genome from each single cell can be amplified using 15 base oligonucleotide random primer. The greatest advantage of PEP-PCR is the ability to investigate several loci simultaneously and confirm results by analysing multiple aliquots for each locus. This technique led to the development of preimplantation genetic disease diagnosis using blastomere from early embryo, sperm, polar body and oocyte. In this study, we applied PEP-PCR in 20 cases of single amniocyte and 20 cases of single chorionic villus cell for the clinical application of the prenatal and preimplantational genetic diagnosis. We analysed 7 gene loci simultaneously which are 46, 47 exons related to dystrophin gene, two VNTR (variable number tandem repeat) markers using 5'toysIII, 3'CA related to dystrophin gene and DYZ1, DYZ3, DYS14 regions on chromosome Y. In all the tests, 97.5% of PEP-PCR amplifications with single cells were successful. We obtained 38/40 (95%) accuracy in gender determination through chromosome analysis comparison. Therefore, these results have significant implications for a sperm or oocyte analysis and prenatal or preimplantational genetic diagnosis.

PURPOSE: The objectives of this study were to determine the prevalence, incidence, and risk factors for postoperative surgical site infections (SSIs) after craniotomy. METHODS: This study was a retrospective case-control study of 103 patients who had craniotomies between March 2007 and December 2008. A retrospective review of prospectively collected databases of consecutive patients who underwent craniotomy was done. SSIs were defined by using the Centers for Disease Control criteria. Twenty-six cases (infection) and 77 controls (no infection) were matched for age, gender and time of surgery. Descriptive analysis, t-test, chi-square-test and logistic regression analyses were used for data analysis. RESULTS: The statistical difference between cases and controls was significant for hospital length of stay (>14 days), intensive care unit stay more than 15 days, Glasgrow Coma Scale (GCS) score (< or =7 days), extra-ventricular drainage and coexistent infection. Risk factors were identified by logistic regression and included hospital length of stay of more than 14 days (odds ratio [OR]=23.39, 95% confidence interval [CI]=2.53-216.11) and GCS score (< or =7 scores) (OR=4.71, 95% CI=1.64-13.50). CONCLUSION: The results of this study show that patients are at high risk for infection when they have a low level of consciousness or their length hospital stay is long term. Nurses have to take an active and continuous approach to infection control to help with patients having these risk factors.
