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.

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.

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.

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.

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.

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: Biologic disease-modifying antirheumatic drugs (bDMARDs) extend the treatment choices for rheumatoid arthritis patients with insufficient response or intolerance to conventional DMARDs (cDMARDs). These agents have considerable efficacy compared with conventional DMARDs, but only a few head-to-head comparisons among these agents have been performed. The objective of this systematic review and network meta-analysis (NMA) was to compare the relative efficacy of Certolizumab with conventional DMARD to licensed bDMARD with cDMARD therapy for patients who failed to prior cDMARD treatment under the condition of the reimbursement coverage criteria in Korea. METHODS: A systematic review was conducted using MEDLINE and Cochrane library. Key endpoints were the American College of Rheumatology (ACR) responses of 20/50/70 at six months. Bayesian outcomes were calculated as median of treatment effect, probability of the best, Odds Ratio (OR) and probability that OR was greater than one. RESULTS: Compared with other bDMARDs, Certolizumab were associated with higher or comparable ACR response rates; in ACR20, the OR (probability of OR>1) was 2.08 (92.6%) for Adalimumab, 1.86 (85.7%) for Etanercept, 1.89 (79.5%) for Golimumab, 2.36 (92.1%) for Infliximab, 1.79 (87.0%) for Abatacept, 1.74 (80.8%) for Rituximab and 1.82 (86.8%) for Tocilizaumab. In ACR50 and ACR70, the ORs did not present significant differences. CONCLUSION: Certolizaumab with cDMARD was more effective or comparable than other bDMARDs in patients who failed prior cDMARD treatment.

PURPOSE: Peripheral blood stem cell transplantation (PBSCT) has recently been used to rescue from myelosuppression following high-dose chemo-radiotherapy in patients with leukemia and solid tumor. Nevertheless, few data are still available on PBSC collection in pediatric patients, owing to technical problems. The time of stem cell harvest and the mobilization regimen may play important roles in terms of achieving adequate numbers of stem cells by leukapheresis. In this study, we analyse; 1) the technical aspects of leukapheresis as to feasibility and safety, 2) the optimal timing for PBSC collection after cytokine-based mobilizing regimens, 3) the engraftment kinetics. Method: A total of 93 leukapheresis was performed 22 children by Fenwall CS 3000 continuous cell separator, of whom 15 children weighed less than 25 kg. To mobilize hematopoietic stem cells into circulation, hematopoietic growth factor plus chemotherapy were used. Nineteen patients underwent autologous peripheral blood stem cell transplantation. RESULTS: The mean body weight was 25.3 kg (range: 10 to 56 kg). A total of 3 to 12 L of blood was processed (mean 265.4 65.9 mL/kg) for 2.5 to 5 hours (mean 3.15 hours). Extracorporeal line was primed with packed red blood cells below 25 kg. Serious morbidity was not noted. Each apheresis products contained a mean of 2.41 1.63x108 mononuclear cells/kg, 2.83 3.40x106 CD34 cells/kg, 9.30 10.3x104 colony forming unit (CFU-GM)/kg, respectively. Absolute neutrophil count (r=0.38, P<0.01) and CD34 cell count (r=0.65, P<0.001) on the day of leukapheresis seemed to predict the CFU-GM count collected in leukapheresis. A significant statistical correlation between the number of infused CFU-GM and the time to achieve an absolute neutrophil count of greater than 500/mm3 (P<0.01) was found. CONCLUSION: Leukapheresis for PBSCT seemed to be feasible and reliable in pediatric patients, conferring no major additional risks than adult patients, only if red cells are primed in extracorporeal line for small children. Absolute neutrophil count and CD34 cell number seemed to predict the timing of leukapheresis. In the PBSCT patient, engraftment was influenced by the infused CFU-GM count and bone marrow environment.

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.
