PURPOSE: The aim of this study is to develop a salivation stimulation method and to verify the effect of a salivation stimulation method on xerostomia in colon cancer patients after surgery. METHODS: This study targeted 21 in the experimental group and 22 in the control group, who were diagnosed with colon cancer and underwent surgery at A university hospital. The salivation stimulation method consists of tongue movement for stimulating minor salivary glands in mouth and a parotid gland and submandibular gland massage with hands. The method was applied four times a day for 2 days the next day after surgery. RESULTS: On the first postoperative day, the experimental group showed a significantly larger amount of salivation than the control group (p=.010). On the second postoperative day, the experimental group showed a significantly larger amount of salivation than the control group (p<.001). On the first postoperative day, the subjective xerostomia scores in the experimental group and control group were not statistically significant (p=.165). On the second postoperative day, the experimental group showed a significantly lower subjective xerostomia score than the control group (p=.001). CONCLUSION: It is considered that providing cancer patients with this salivation stimulation method after surgery would reduce discomfort caused by xerostomia.

Anatomy is knowledge about structure and function of human body. However, with on medical course the vast amount of content, many students have difficulties and burdens about anatomy. The purpose of this study was to investigate the effect of bingo game to improve understanding and learning effect of anatomy. This study was carried out in September, 2018, at 53 medical students. After conducting the bingo, the students were asked about the usefulness, grade reflection, concern, continuation, necessity, appropriate time and interest of bingo. And the relationship between bingo results and grades was also investigated. A total of seven bingo games were with an average of 3.6 bingo (0-11). There was a positive response to the usefulness (3.74 ± 0.92), interest (3.94 ± 0.82), continuation (3.55 ± 1.10), necessity (3.51 ± 1.01), and concern (3.72 ± 1.01) of bingo. However, the appropriateness of the time was neutral (3.26 ± 1.02), and there were negative opinions about grade reflection of bingo (1.40 ± 0.86). The grade of anatomy subject showed a positive correlation with the results of the bingo, but did not reach statistical significance (r = 207, p = 0.088). In addition to anatomy, histology, microbiology, and pharmacology were also considered to be useful educational methods for bingo. Bingo may be useful in medical school curriculum, especially in Anatomy. More research is needed to improve learning efficiency through bingo.

Purpose: This study aimed to compare the effects of oral swab and non-swab using cold water gauze on patients’ thirst and oral status following nasal surgery under general anesthesia. Methods: A non-equivalent control group was applied. Participants were divided into a control group (n=30) that was treated by cared for with cold water gauze application without oral swab and an experimental group (n=29) that was treated cared for with oral swab using cold water gauze after nasal surgery at the G University Hospital in Korea. Data were collected from May 14, 2020, to April 30, 2021, and analyzed using descriptive statistics, a chi-squared test, independent t-test, Wilcoxon signed-ranks test, and Mann-Whitney test. Results: The results showed no significant differences between the two groups in thirst (U=-0.04, p=.693) and overall oral condition (U=-0.34, p=.813) after the intervention. However, participants’ thirst and oral condition were significantly improved in each group after intervention. Conclusions It was confirmed that both oral care methods reduced thirst and improved oral condition after nasal surgery. These findings indicate the need for intervention for patients’ thirst and oral condition after nasal surgery. Furthermore, they show that these oral care protocols can be used as a safe and effective nursing intervention for patients who undergo nasal surgery under general anesthesia.

Foreign body impaction in airway is life-threatening as it can cause total airway obstruction. Such foreign bodies are removed under bronchoscopy in most patients. In some patients, however, the cardiopulmonary condition becomes unstable to undergo ventilating bronchoscopy under general anesthesia to remove the foreign body. In these conditions, extracorporeal membrane oxygenation (ECMO) can be adopted for cardiopulmonary support to stabilize the patient while removing the foreign body. ECMO supports tissue oxygenation and has been shown to improve survival of patients with adult respiratory distress syndrome. ECMO allows lungs to reserve their functions and decreases further lung injuries. The authors report one case of extensive tracheal inflammatory crust removed by ventilating bronchoscopy under tracheostomy and ECMO.

Adequate vitamin D status is essential for bone health. New randomized controlled trials investigating the effect of vitamin D supplementation on bone health have recently been published. This position statement updates and expands on the previous 2015 position statement of the Korean Society for Bone and Mineral Research on the adequate vitamin D status for healthy older adults (age ≥ 70 years) and those at high risk of osteoporosis and fracture (adults on osteoporosis medications) to maintain serum 25-hydroxy-vitamin D (25[OH]D) levels ≥ 20 ng/mL but < 50 ng/mL. A serum 25(OH)D level of 30 ng/mL may be beneficial for those on anti-resorptives. Vitamin D can be obtained from ultraviolet light exposure and diet. To reach the target vitamin D status through intake, adults must consume at least 400 IU/day to reach 20 ng/mL and 800 to 1,000 IU/day to reach 30 ng/mL. Foods familiar to the Korean diet that are high in vitamin D content or consumed frequently enough to positively impact vitamin D status are introduced in addition to the amount required to help reach one’s target vitamin D status.

The incidence of retropharyngeal abscess has been decreased with the use of antibiotics, but it can cause critical complications such as airway obstruction, aspiration pneumonia, disseminated intravascular coagulation, mediastinitis, or sepsis. A vacuum-assisted closure (VAC) device is a surgical drain that can help prevent reaccumulation of purulent collections. We present one case of retropharyngeal abscess treated by VAC and highlight the utility of VAC in the management of retropharyngeal abscess.

BACKGROUND: To investigate the risk factors for vaginal infections and antimicrobial susceptibilities of vaginal microorganisms among women who experienced preterm birth (PTB), we compared the prevalence of vaginal microorganisms between women who experienced preterm labor (PTL) without preterm delivery and spontaneous PTB. METHODS: Vaginal swab specimens from 126 pregnant women who experienced PTL were tested for group B streptococcus (GBS), Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma urealyticum, Chlamydia trachomatis, Trichomonas vaginalis, Neisseria gonorrhoeae, Treponema pallidum, herpes simplex virus (HSV) I and II, and bacterial vaginosis. A control group of 91 pregnant women was tested for GBS. Antimicrobial susceptibility tests were performed for GBS, M. hominis, and U. urealyticum. RESULTS: The overall detection rates for each microorganism were: U. urealyticum, 62.7%; M. hominis, 12.7%; GBS, 7.9%; C. trachomatis, 2.4%; and HSV type II, 0.8%. The colonization rate of GBS in control group was 17.6%. The prevalence of GBS, M. hominis, and U. urealyticum in PTL without preterm delivery and spontaneous PTB were 3.8% and 8.7% (relative risk [RR], 2.26), 3.8% and 17.3% (RR, 4.52), and 53.8% and 60.9% (RR, 1.13), respectively, showing no significant difference between the 2 groups. The detection rate of M. hominis by PCR was higher than that by culture method (11.1% vs. 4.0%, P=0.010). The detection rates of U. urealyticum by PCR and culture method were 16.7% and 57.1%, respectively. CONCLUSIONS: There was no significant difference in the prevalence of GBS, M. hominis, and U. urealyticum between the spontaneous PTB and PTL without preterm delivery groups.

PURPOSE: Retrovirs-mediated transduction of target genes into bone marrow progenitor cells or peripheral lymphocytes has been less optimal due to low efficiency and minimal expression on long-term analysis. This study aims to establish an efficient 4-day culture condition for the increased transduction efficacy into CD34+ cells selected on umbilical cord blood by comparing combination of various cytokines. METHODS: CD34+ cells from umbilical cord blood selected by Isolex-50R were incubated with supernatant containing XM5/PA317 vector for 96 hours. Cytokine combinations were used including IL-6+SCF, IL-6+IL-3+SCF, and IL-6+IL-3+SCF+TPO. Methylcellulose colony assay was done after culture. The data were expressed as mean+/-SD with 3 experiments. The efficiency of gene transfer was assessed by the ability of transduced CFU-GM to grow in the presence of G418 and PCR analysis of individual CFU-GM. RESULTS: The mean recovery rate of CD34+ cells after purification was 22%, and the purity of the final CD34+-enriched fraction was 82+/-13% (mean+/-SD). After a 4-day culture, the cell number increased 5~10 fold in each culture condition. The transduction efficiency evaluated by both G418-screened CFU-GM and PCR-positive CFU-GM with the above cytokine combinations was 46% and 64%, 41% and 57%, and 28% and 45%. However, there were no significant differences of colony counts between the cytokine combinations. CONCLUSION: We were unable to establish the best recipe of cytokine combination as the number of experiments was small and we tried only a fixed concentration of cytokines. For the future, the study of developing a novel vector, a better condition of transduction, and better combination of cytokines is warranted to attain the goal of highly effective, long-lasting method of gene transfer.
