Uterine perforation related with dilatation and curettage (D&C) is an uncommon event. Combined complications such as hemorrhage, adjacent organ injury, and omental incarceration may require an emergent surgical treatment. These are usually evident immediately or several days after the D&C, and a delayed presentation of uterine perforation are extremely rare. Herein, we report a rare case of omental incarceration presenting as a hyperechoic endometrial mass in a postmenopausal woman, diagnosed twenty-three years after the D&C. According to this case, when we encounter a hyperechoic endometrial lesion penetrating the uterine wall in women with a history of an intrauterine procedure such as D&C, we need to consider the possibility of an incarcerated omentum.

The Non-incision "double eyelid" operation reported by Mikamoto of Japan in 1896 has the advantage of shorter operating time, less morbidity and minimal scarring thus more natural final appearance. Incidence complications of this procedure such as disappearance of the fold, asymmetry, and inclusion cyst has been reported to be higher than the incision method and there has been reports of complication rates of up to 30%. The surgeon and the patient are most worried about the complete disappearance of the surgical palpebral fold. The complications of Non-Incision ""double eyelid"" operation was evaluated in 190 patients who were available for follow up of more than 1 year. Classification of the complications which required revision surgery was classified and evaluated. There were no major complications such as blindness, retrobulbar hematoma, and blepharoptosis. Total number of complications requiring reoperation: 24(100%). The most common reoperation procedure that we experienced was asymmetry which occurred in 10(42%) patients followed by lowering of the fold line and disappearance of the fold with 6(25%) cases each. All these patients were taken back to surgery and were corrected by Non-incision method with favorable results. Conclusively, 24 complications of Non-incision double eyelid procedure experienced in 190 patients. Disappearance of the palpebral fold was seen in 6 patients who were corrected by another Non-incision technique with excellent results. The complete disappearance of the fold was experienced in very few patients and correction of this complication was satisfactory. Thus, disappearance of the fold after Non-incision double eyelid procedure should not be termed by the patient or the surgeon with full under- standing of the procedure.

Journal of Korean Academy of Nursing 2022;52(5):511-521
Purpose:
This study aimed to examine the moderating effect of organizational justice on the relationship between self-efficacy and nursing performance among clinical nurses.
Methods:
In January 2021, a cross-sectional survey was conducted with 224 clinical nurses recruited from a university-affiliated hospital in Suwon, South Korea. Participants completed online-based, self-report structured questionnaires. Collected data were analyzed using multiple regression and a simple model of PROCESS macro with a 95% bias-corrected bootstrap confidence interval.
Results:
Self-efficacy and organizational justice were found to be significant predictors of nursing performance. These two predictors explained the additional 34.8% variance of nursing performance in the hierarchical regression model, after adjusting the other covariates. In addition, organizational justice moderated the relationship between self-efficacy and nursing performance among the clinical nurses. In particular, at low self-efficacy level, participants with high organizational justice had higher nursing performance compared to those with low organizational justice.
Conclusion
Enhancing organizational justice can be used as an organizational strategy for improving the organizational culture in terms of distribution, procedure, and interaction. Ultimately, these efforts will contribute to the improvement of nursing performance through a synergistic effect on organizational justice beyond nurses’ individual competency and self-efficacy.

Vitamin C acts as a antioxidants and as free radical scavengers in biological systems. The objective of this study was to examine whether the administration of vitamin C could improve the skin flap survival. Sprague-Dawley rats (n = 40) were divided into 4 groups (n = 10); normal saline, vitamin C 200 mg/day, vitamin C 500 mg/day, vitamin C 1000 mg/day were injected subcutaneously to each group (n = 10). A classic caudally based random flap (2 X 7 cm) was elevated on the dorsum of rats and then sutured to its normal position. On the 3rd, 7th, 14th days postoperatively each animal was evaluated for percentage area of flap survival by paper template technique, thereafter rats were sacrificed and we obtained tissue from the distal ends of the flap. Following is our results. 1) The experimental group treated with vitamin C revealed an increased rate of random pattern skin flap survival compared with the control group (p < 0.005). 2) There was correlation of vitamin C dosage with flap survival rate (Spearman's correlation coefficient = 0.971). 3) The biopsy of the control group showed extensive atrophy and necrosis. However, New capillary proliferation and collagen deposition were noted in the vitamin C 200 mg and 500mg treated group. In the vitamin 1000 mg group, microscopic findings were very alike compared with normal rat skin texture. Finally, we concluded that the Vitamin C supplement increases survival rate of random pattern flap in rat skin flap model, and flap survival is correlated with vitamin C dosage.

Immune Network 2003;3(1):38-46
BACKGROUND: Platelet-activating factor (PAF) induces nuclear factor (NF)-kappaB activation and angiogenesis and increases tumor growth and pulmonary tumor metastasis in vivo. The role of NF-kappaB activation in PAF-induced angiogenesis in a mouse model of Matrigel implantation, and in PAF-mediated pulmonary tumor metastasis were investigated. METHODS: Angiogenesis using Matrigel and experimental pulmonary tumor metastasis were tested in a mouse model. Electrophoretic mobility shift assay was done for the assessment of NF-kappaB translocation to the nucleus. Expression of angiogenic factors, such as tumor necrosis factor (TNF)-alpha, interleukin (IL)-1alpha, basic fibroblast growth factor (bFGF), and vascular endothelial growth factor (VEGF) were tested by RT-PCR and ELISA. RESULTS: PAF induced a dose- and time-dependent angiogenic response. PAF-induced angiogenesis was significantly blocked by PAF antagonist, CV6209, and inhibitors of NF-kappaB expression or action, including antisense oligonucleotides to p65 subunit of NF-kappaB (p65 AS) and antioxidants such as alpha-tocopherol and N-acetyl-L-cysteine. In vitro, PAF activated the transcription factor, NF-kappaB and induced mRNA expression of TNF-alpha, IL-1alpha, bFGF, VEGF, and its receptor, KDR. The PAF-induced expression of the above mentioned factors was inhibited by p65 AS or antioxidants. Also, protein synthesis of VEGF was increased by PAF and inhibited by p65 AS or antioxidants. The angiogenic effect of PAF was blocked when anti-VEGF antibodies was treated or antibodies against TNF-alpha, IL-1alpha, and bFGF was co-administrated, but not by antibodies against TNF-alpha, IL-1alpha, and bFGF each alone. PAF-augmented pulmonary tumor metastasis was inhibited by p65 AS or antioxidants. CONCLUSION: These data indicate that PAF increases angiogenesis and pulmonary tumor metastasis through NF-kappaB activation and expression of NF-kappaB-dependent angiogenic factors.

OBJECTIVE: This study was conducted to investigate the cognitive factors that can longitudinally predict the response to treatment in patients with schizophrenia. METHODS: The subjects were 49 patients with schizophrenia who were newly hospitalized in an acute psychiatry ward and had not been treated with medication for at least 8 weeks prior to the study. The symptoms and cognitive functions of the patients were evaluated at baseline before treatment (T0), at eight weeks after treatment (T1), and one year after treatment (T2). Clinical symptoms were assessed using the PANSS, and cognitive functions were estimated using the Vigilance Test, Cognitrone Test, Wisconsin Card Sorting Test (WCST), and the Korean version of the Memory Assessment Scales (K-MAS). RESULTS: The patient group showed marked impairments in cognitive function when compared to the normal group, but the patients' clinical symptoms and cognitive functions improved after drug treatment. The patients also showed consistent improvement in verbal and nonverbal memory function as time progressed. Furthermore, there was a significant correlation between clinical symptoms and cognitive functions in the patient group. The cognitive variables that best predicted treatment response and prognosis were total errors on the WCST and immediate list recall component of the K-MAS. It was also shown that the number of total errors on the WCST was a better cognitive predictor than the number of errors in immediate recall. CONCLUSION: The results of the present study show that the neurocognitive functions of patients with schizophrenia can be stabilized with treatment intervention, that treatment response is related to improvement in cognitive function, and that cognitive domains, especially executive function, can predict treatment response and prognosis in patients with schizophrenia.

PURPOSE: This study was to analyse the factors affecting youth smoking, especially self-efficacy and perceived social norm, based on the stage of change. METHODS: A self-reported survey was conducted during the period from the 21st of April to the 17th of May, 2008. Data were collected from 10,707 students of 12 middle schools in Seoul, Gyeonggi-do, and Incheon. The data were analysed with SPSS/WIN 15.0. RESULT: The smoking possibility was 2.18 times higher in the male students than in female students, and 1.76 times higher in 8th-grade students and 2.48 times higher in 9th-grade students than in 7th-grade ones. Smoking possibility increased when students had more experience in alcohol, more friends who smoke, or worse relationship with their parents. Also this study showed that high-level self-efficacy and perceived social norm were acting as inhibiting factors of smoking. CONCLUSION: To reduce the youth's smoking rate, smoking prevention programs should provide educational chances to learn knowledge and skills on how to reject smoking temptation. Also, someone significant like parents should make it clear to the youth that they do not want their children to smoke.
