Uterine prolapse with pregnancy is rare condition. The overall incidence is 1/10000- 15000 deliveries. The complications from uterine prolapse range from minor cervical ulceration and infection to fetal death or uterine rupture. The fetal mortality was as high as 22% mainly due to prematurity, respiratory infection. The management of this condition is focused on preventing late occurrence of prolapse during pregnancy and continued reduction. We present a case of uterine prolapse in pregnancy with a brief review of the literature.

Uterine tumors resembling ovarian sex-cord tumors (UTROSCT) are very rare tumors that occur mainly in the uterine fundus of women in reproductive age. These tumors can be classified into group 1 and group 2 by histological results. In group 1, epithelial-like differentiation is partially observed in the tumors. In group 2, sex-cord elements are predominant in uterine mural mass. We experienced UTROSCT group 1 in a 29-year-old woman who complained of severe abdominal pain that started one week after delivery and UTROSCT group 2 case in a 49-year-old woman who complained of dysfunctional uterine bleeding. We report two different types of UTROSCT cases that we experienced.

In the case of crown-root fracture due to traumatic injury in anterior tooth and the fracture margin is located subgingivally,forced eruption has been proposed for the reconstruction of deficient bone and soft tissue. Forced eruption is one of the easiestorthodontic approaches that can have an acceptable outcome and prognosis, and has a low incidence of relapse. However, using heavy forces or very fast movements can also cause tissue damage or ankylosis. The following case reports present forced eruption as treatment option of crown fracture in maxillary anterior teeth.

Neuroimaging of the brain is useful diagnostic evaluation of patients with hepatic encephalopathy msofar as it is able to exclude other causes of abno rmal mental status. Recently, changes of basal ganglia on MRI characteriwd by increased signal mtensity on Tl-weighted images were reported m patients with liver cirrhosis. Signal abnormality involves mainly the globus pallidus and seems to be specific for patients with chronic liver disease. Its pathogenesis and significance are obscure, and no pathological reports have been made. We experienced 3 cases of Chronic acquired hepatic failure whose MRI showed increased signal in-tensity in the basal ganglia on Tl-weighted imaging. Our findings su-ggest that basal ganglia signal abnormality could arise as a marker of brain impairment related to deposition of an unidentified paramagnetic substance or altered intracellular water relaxation.

Background:
The use of dental floss along with a toothbrush is a well-known oral hygiene product that effectively removes dental plaque and reduces the risk of dental caries and periodontal disease. Despite the fact that various types of floss are being used, flossing methods based on the thread type are being taught. In addition, personal preference according to the floss types has not been investigated. In this study, individual preferences according to the floss types were investigated by experiencing various types of dental floss to both floss users and non-users. In addition, the change in intention to use dental floss in the future after flossing experience of non-users was investigated.
Methods:
General public participated in the individual interview survey (n=419). Subjects responded to the questionnaire after using all of the thread type, Y-type, and C-type floss. All statistics were expressed frequencies and percentages for categorical variables, and the chi-squared test was used to determine the statistical significance of associations between the variables.
Results:
As a result of the analysis, the preference of C-type floss was highest in both floss users and non-users. The biggest reason for not using dental floss was not knowing the necessity of flossing (36.4%). In addition, both floss users and non-users responded that C-type floss was suitable for flossing in the anterior and posterior regions. The change in the positive future intention to use dental floss after flossing experience of non-users was statistically significantly associated with age.
Conclusion
This result suggests that there is a need to provide education on how to use dental floss in various forms. Based on this, it will be possible to lead a change in individual's attitude for future oral health through active and continuous flossing experience.

PURPOSE: This study was conducted to update the existing evidence-based nursing clinical practice guideline in management of pressure injury in South Korea. METHODS: The update process underwent the 22 steps according to the update method based on the international standards. RESULTS: The updated nursing practice guideline for pressure injury consists of 4 domains and 436 recommendations. The numbers of recommendations in each domain were 25 for hospital policies, 51 for assessment, 350 for prevention and management, and 10 for education. There were 2.5% of A, 13.3% of B, 84.2% of C in terms of grading of recommendations. Among these, the major revision was done in 32 recommendations (7.4%). A total of 299 recommendations (68.6%) were added newly. Minor revisions, such as change or addition of some words, were also made in 25 recommendations(5.7%). No change was made in 80 recommendations (18.3%) compared to the previous ones. CONCLUSION: The nursing practice guideline for pressure injury has been updated. This updated guideline can be used as educational materials for both healthcare workers and patients with pressure injury.

Objective:
Although serum ferritin is considered the best measure of total body iron, with low levels indicating iron deficiency, recent studies have shown that high levels are associated with gestational diabetes, premature birth, and low birth weight. This study aimed to analyze the association between serum ferritin levels in the third trimester of pregnancy and low birth weight and preterm birth.
Methods:
This study included pregnant women who delivered a single fetus at Kangwon National University Hospital between January 2009 and December 2013 and in whom serum ferritin levels were measured between 28 and 34 weeks of gestation. The association between serum ferritin levels measured in the early third trimester of pregnancy and preterm birth and low birth weight infants was analyzed.
Results:
A total of 1,079 women fulfilled the study criteria and had their serum ferritin level measured during the third trimester (28–33.9 weeks of gestation) and later delivered at Kangwon National University Hospital. Comparison of the group with serum ferritin levels above the 75th percentile and those below the 25th percentile at the beginning of the third trimester revealed that the incidence of preterm births (<34 weeks of gestation, <37 weeks of gestation) and low birth weight were significantly higher in the group with serum ferritin levels above the 75th percentile than those below the 25th percentile (p<0.05). When variable factors were controlled through multiple regression analysis, the group whose serum ferritin levels were above the 75th percentile at 30–31.9 weeks of gestation had the highest risk of preterm birth before 34 weeks of gestation (adjusted odds ratio [OR], 7.85; 95% confidence interval [CI], 1.32–29.9) and low birth weight (adjusted OR, 6.49; 95% CI, 2.10–20.0).
Conclusion
In this study, when serum ferritin was high in the third trimester of pregnancy, it was significantly increased with preterm birth (<34 and 37 weeks) and low birth weight. In particular, when serum ferritin levels were high at 30–31.9 weeks of gestation, the risk of premature birth before 34 weeks and low birth weight was statistically highest.

Purpose:
This study aimed to investigate the clinical outcomes of internal iliac artery (IIA) interruption during endovascular aneurysm repair (EVAR) and to identify the risk factors for ischemic complications.
Materials and Methods:
Endovascular treatment was performed in 316 patients with aneurysms or pseudoaneurysms of the abdominal aorta or iliac arteries between March 2006 and January 2022. Medical records and radiological imaging studies were retrospectively reviewed. The incidences of buttock claudication, ischemic colitis, and spinal cord ischemia after IIA interruption were investigated as clinical outcomes. Binary logistic regression analysis were performed to identify the risk factors.
Results:
IIA embolization was performed in 78 patients. Among the 42 patients who underwent IIA flow preservation procedures, the one-month computed tomography detected early failure in five patients. The origin of the IIA was covered with an endograft in ten patients who did not undergo embolization. Eventually, interruption of the IIA by EVAR was observed in 93 patients. Considering preoperative IIA occlusion, there was a total of six patients who did not have at least one IIA patency. Buttock claudication occurred in 32.6% of the patients, and none of the patients had ischemic colitis or spinal cord ischemia. In multivariable analysis, age ≤80 years and isolated iliac artery aneurysm were associated with the development of postoperative buttock claudication.
Conclusion
The most common complication after IIA interruption is buttock claudication; however, critical complications such as ischemic colitis or spinal cord ischemia are rare, even in bilateral IIA occlusion. Adjunctive procedures to preserve bilateral IIA perfusion should be adopted selectively.

Although DNA damage responses (DDRs) are reported to be involved in nitric oxide (NO) production in response to genotoxic stresses, the precise mechanism of DDR-mediated NO production has not been fully understood. Using a genotoxic agent aphidicolin, we investigated how DDRs regulate NO production in bovine aortic endothelial cells. Prolonged (over 24 h) treatment with aphidicolin increased NO production and endothelial NO synthase (eNOS) protein expression, which was accompanied by increased eNOS dimer/monomer ratio, tetrahydrobiopterin levels, and eNOS mRNA expression. A promoter assay using 5’-serially deleted eNOS promoters revealed that Tax-responsive element site, located at −962 to −873 of the eNOS promoter, was respon-sible for aphidicolin-stimulated eNOS gene expression. Aphidicolin increased CREB activity and ectopic expression of dominantnegative inhibitor of CREB, A-CREB, repressed the stimulatory effects of aphidicolin on eNOS gene expression and its promoter activity. Co-treatment with LY294002 decreased the aphidicolin-stimulated increase in p-CREB-Ser133 level, eNOS expression, and NO production. Furthermore, ectopic expression of dominant-negative Akt construct attenuated aphidicolin-stimulated NO production. Aphidicolin increased p-ATM-Ser1981 and the knockdown of ATM using siRNA attenuated all stimulatory effects of aphidicolin on p-Akt-Ser473 , p-CREB-Ser133 , eNOS expression, and NO production. Additionally, these stimulatory effects of aphidicolin were similarly observed in human umbilical vein endothelial cells. Lastly, aphidicolin increased acetylcholine-induced vessel relaxation in rat aortas, which was accompanied by increased p-ATM-Ser1981 , p-Akt-Ser473 , p-CREB-Ser 133 , and eNOS expression. In conclusion, our results demonstrate that in response to aphidicolin, activation of ATM/Akt/CREB/eNOS signaling cascade mediates increase of NO production and vessel relaxation in endothelial cells and rat aortas.
