A 71-yr-old male patient with three vessel coronary artery disease underwent a coronary artery bypass graft. The patient was found to have a large pericardial defect at the apex of the heart that measured approximately 18 cm in circumference. The edge of the pericardial defect impinged on the epicardial coronary arteries. The left phrenic nerve descended via the dorsal boundary of the pericardial defect. Following coronary artery bypass grafting, the pericardial defect was repaired with a polytetrafluorethylene patch. The patient had an uncomplicated postoperative course.

Background: The purpose of this study is to investigate the tooth whitening effect of Listerine Healthy White and provide effective management of extrinsic discoloration by comparing the whitening effects of existing whitening products. Methods: The included study four groups: those using whitening gel, whitening toothpaste, and Listerine Healthy White and a control using artificial saliva. Each group received 40 bovine tooth specimens, which were stained with commonly consumed tooth-coloring-inducing foods; black tea, black coffee, and instant noodles for 72 hours. The specimens were treated with tooth whitening materials for 5 weeks, after which the lightness (L*) was measured weekly using a spectrophotometer. Results: There was a significant difference in lightness among the groups between the 1st and 5th week of treatment for all tooth-coloring-inducing foods (p＜0.05). When comparing the changes in lightness values from before whitening to the 5th week of whitening for all tooth-coloring-inducing foods, the order of change was as follows: whitening gel, whitening toothpaste, Listerine Healthy White, and artificial saliva. Listerine Healthy White showed a significant whitening effect for all toothcoloring-inducing foods (p＜0.05). Particularly, changes in lightness values for specimens stained by black tea after 5 weeks of whitening were in the following order: whitening gel (21.72), whitening toothpaste (14.89), Listerine Healthy White (12.91), and artificial saliva (3.85). For specimens stained by black coffee, the changes in lightness values were in the following order: whitening gel (12.99), whitening toothpaste (9.66), Listerine Healthy White (7.91), and artificial saliva (3.12). Lastly, changes in lightness values for specimens stained by instant noodles were as follows: whitening gel (10.84), whitening toothpaste (9.85), Listerine Healthy White (7.71), and artificial saliva (2.61). Conclusion Listerine Healthy White exhibits continuous whitening effects over time, and for consumers seeking convenient ways to achieve tooth whitening effects at home, consistent use of Listerine Healthy White is recommended.

PURPOSE: This paper examined the relationship between knowledge differences of maternal oral health and of relevant demographic variables. METHODS: Participants included 239 pregnant women who were recruited from Women's Hospital located in B city who agreed to participate in this study. The data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation analysis using the SPSS 21.0 program. RESULTS: Maternal knowledge of oral health was moderate level (10.22±2.36). Scores of maternal knowledge of oral health were different according to age, education, occupation, parity, and dental care experience in pregnancy. Level of oral healthcare knowledge was weakly related to age and education. CONCLUSION: Consequently, it is necessary to encourage pregnant women to take part in oral health education program during antenatal care.

BACKGROUND: Backache is a common complication following anesthesia and surgery. Previous studies indicated that the use of a lumbosacral wedge was effective in reducing the incidence of postoperative backache. We investigated the effective inflation pressure of an inflatable wedge in preventing postoperative backache following spinal anesthesia and surgery in the lithotomy position. METHODS: A pilot study established a mean comfortable pressure for the wedge when used to support the lumbar curvature. In males and females, the mean pressure values were 23.6 +/- 3.1 mmHg and 18.9 +/- 3.7 mmHg, respectively. The design of the main study was a randomized, controlled trial involving the use of a wedge intra-operatively in patients undergoing spinal anesthesia and urological surgery in the lithotomy position. Fifty male and 50 female patients were included in the main study and randomly allocated to the control or study group. In the study group, the wedge was inserted immediately after the induction of anesthesia and maintained during surgery. On the first day after surgery, all patients were asked whether they had backache. If there was backache, the degree of pain was noted using the numeric rating scale (NRS). RESULTS: In the study and control groups of male patients, the incidence of backache was 16% and 24%, respectively. There was no significant difference between the two groups. In the study and control groups of female patients, the incidence of backache was 20% and 52%, respectively (P < 0.05). Where backache occurred, there was no significant difference in its severity between the study and control groups. CONCLUSIONS: The effective pressure value of an inflatable wedge in preventing postoperative backache following spinal anesthesia and surgical operation in lithotomy position was 19 mmHg in female patients.

Renal infarction usually occurs in patients with atrial fibrillation, valvular heart disease, trauma, renal artery stenosis, atherosclerosis, vasculitis, and hypercoagulable state. Protein C or S deficiency is an uncommon condition among hypercoagulable states and manifests deep vein thrombosis, pulmonary thromboembolism, cerebrovascular accident. In this report, we present a case of renal infarction occurred in 36-year-old male without underlying diseases except a family history of thromboembolism. He was admitted to our hospital due to an abrupt and continuous left flank pain. He had no previous history of an arterial or venous thrombosis. Tomography and renal angiography showed a left renal artery occlusion. He was treated with heparin and warfarin therapy. In laboratory tests, Protein C antigen level and protein S activity was 51.80% (72-160%) and 48% (65-140%). Thus, we concluded that renal infarction was secondary to combined type 1 protein C deficiency and type 2 protein S deficiency.

OBJECTIVES: The purpose of this study was to evaluate the factors which affect pulmonary function in shipyard workers in order to build a body of basic information that can be used to prevent and manage pulmonary disorders in the future. METHODS: We studied the respiratory symptoms, smoking history, chest radiographies, and pulmonary functions of 793 workers associated with two shipyards from April 2009 to July 2009. The workers were subdivided into 3 groups by job type: welders, grinders, and machinist-managers. The data was analyzed according to job type and other possible impact factors. RESULTS: Significant differences among job type were seen with dyspnea and coughing during working hours and in the morning. In pulmonary functions, there were significant differences in forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF), and maximal mid-expiratory flow (MMEF) (except FEV1/FVC%) among job types. Grinders especially showed significantly lower figures in the indices of FEV1, FVC, and MMEF. CONCLUSIONS: Pulmonary function was significantly lower in grinders. Grinders seem to be affected by exposure to a combination of dust particles (silica, lead, and manganese) and irritant gases in the workplace. These results suggested that workers and health officials should work together to adopt technical preventive measures, such as having well- ventilated work areas and appropriate respiratory protective devices.

Background: Numerous studies have investigated methods of predicting postoperative pulmonary complications (PPCs) in lung cancer surgery, with chronic obstructive pulmonary disease (COPD) and low forced expiratory volume in 1 second (FEV1 ) being recognized as risk factors. However, predicting complications in COPD patients with preserved FEV 1 poses challenges. This study considered various diffusing capacity of the lung for carbon monoxide (DLCO ) parameters as predictors of pulmonary complication risks in mild COPD patients undergoing lung resection. Methods: From January 2011 to December 2019, 2,798 patients undergoing segmentectomy or lobectomy for non-small cell lung cancer (NSCLC) were evaluated. Focusing on 709 mild COPD patients, excluding no COPD and moderate/severe cases, 3 models incorporating DLCO , predicted postoperative DLCO (ppoDLCO ), and DLCO divided by the alveolar volume (DLCO /VA) were created for logistic regression. The Akaike information criterion and Bayes information criterion were analyzed to assess model fit, with lower values considered more consistent with actual data. Results: Significantly higher proportions of men, current smokers, and patients who underwent an open approach were observed in the PPC group. In multivariable regression, male sex, an open approach, DLCO <80%, ppoDLCO <60%, and DLCO /VA <80% significantly influenced PPC occurrence. The model using DLCO /VA had the best fit. Conclusion Different DLCO parameters can predict PPCs in mild COPD patients after lung resection for NSCLC. The assessment of these factors using a multivariable logistic regression model suggested DLCO /VA as the most valuable predictor.
