Purpose: The purpose of this study was to investigate the effects of thermotherapy on gas pain, post-operative resilience, and body temperature discomfort among patients who received laparoscopic myomectomies. Methods: The experimental group consisted of 62 patients with thermotherapy and the control group consisted of 60 patients. Thermotherapy was applied individually to the experimental group four hours after surgery. The collected data was analyzed using descriptive statistics, t-tests, ${\chi}^2$-tests, and repeated measures of analysis of variance, using IBM SPSS Statistics version 18. Results: The results showed no significant interaction effect between the group and time of measurement in gas-related pain in the experimental group. For gas-related pain, there was significant difference in right shoulder pain at 24 hours (t=-4.222, p=.000), 48 hours (t=-3.688, p=.000), 72 hours (t=-2.250, p=.028), and left at 24 hours (t=-3.727, p=.000), 48 hours (t=-4.150, p=.000), and 72 hours (t=-2.482, p=.016) and both shoulders at 24 hours (t=-2.722, p=.009) and 48 hours (t=-2.525, p=.014). There was no significant difference in epigastric pain, excluding both epigastric pain at 48 hours (t=2.908, p=.005), 72 hours (t=3.010, p=.004), but there was a significant difference in objective body temperature discomfort (t=2.895, p=.008). Conclusion: Thermotherapy relieved shoulder gas-related pain and objective body temperature discomfort. It needs to be developed and applied to improve post-operative discomfort in patients with laparoscopic hysterectomies.

Purpose: The aim of this study was to evaluate clinical and radiographic changes and the survival rate after periodontal surgery using deproteinized bovine bone mineral (DBBM) with 10% collagen or DBBM with a collagen membrane in endo-periodontal lesions. Methods: A total of 52 cases (41 patients) with at least 5 years of follow-up were included in this study. After scaling and root planing with or without endodontic treatment, periodontal regenerative procedures with DBBM with 10% collagen alone or DBBM with a collagen membrane were performed, yielding the DBBM + 10% collagen and DBBM + collagen membrane groups, respectively. Changes in clinical parameters including the plaque index, bleeding on probing, probing pocket depth, gingival recession, relative clinical attachment level, mobility, and radiographic bone gains were evaluated immediately before periodontal surgical procedures and at a 12-month follow-up. Results: At the 12-month follow-up after regenerative procedures, improvements in clinical parameters and radiographic bone gains were observed in both treatment groups. The DBBM + 10% collagen group showed greater probing pocket depth reduction ($4.52{\pm}1.06mm$) than the DBBM + collagen membrane group ($4.04{\pm}0.82mm$). However, there were no significant differences between the groups. Additionally, the radiographic bone gain in the DBBM + 10% collagen group ($5.15{\pm}1.54mm$) was comparable to that of the DBBM + collagen membrane group ($5.35{\pm}1.84mm$). The 5-year survival rate of the teeth with endo-periodontal lesions after periodontal regenerative procedures was 92.31%. Conclusions: This study showed that regenerative procedures using DBBM with 10% collagen alone improved the clinical attachment level and radiographic bone level in endo-periodontal lesions. Successful maintenance of the results after regenerative procedures in endo-periodontal lesions can be obtained by repeated oral hygiene education within strict supportive periodontal treatment.

Background: Cerebral state index (CSI) is an anesthesia depth monitor alternative to bispectral index (BIS). Published comparative studies have used propofol or sevoflurane. However, studies using desflurane have not been reported yet. Different volatile anesthetics have different electroencephalography signatures. The performance of CSI may be different in desflurane anesthesia. Therefore, the objective of this study was to compare CSI and BIS during desflurane anesthesia. Methods: Thirty-three patients were recruited. Desflurane and remifentanil were used to maintain general anesthesia. BIS and CSI were recorded simultaneously every minute. End-tidal concentration of desflurane was maintained at 4% from the beginning of surgery for 5 minutes. Pairwise data of CSI and BIS were obtained five times at one-minute intervals. This process was repeated in the order of 6%, 8%, and 10%. Results: BIS and CSI were negatively correlated with the end-tidal concentration of desflurane with a similar degree of correlation (correlation coefficient BIS: -0.847, CSI: -0.844). The relationship between CSI and BIS had a good linearity with a slope close to 1 ($R^2=0.905$, slope = 1.01). For the relationship between CSI and BIS at each end-tidal concentration of desflurane, CSI and BIS showed good linearity in 4% and 10% ($R^2=0.559$, 0.540). However, the linearity and slope were decreased in 6% and 8% ($R^2=0.163$, 0.014). Conclusions: CSI showed an equivalent degree of overall performance compared to BIS in desflurane anesthesia. Accounting for previous literature, CSI can be used as a good substitute for BIS regardless of the kind of anesthetics used.

Purpose: Forward head posture (FHP) is known to cause pain, limit range of motion, and reduce quality of life. Joint mobilization is commonly used to correct FHP. However, no study has compared cervical, thoracic, and combined cervical and thoracic joint mobilization for FHP. The aim of this study was to investigate and compare the effects of each mobilization technique on range of motion in the sagittal plane and pain in patients with FHP. Methods: Forty-five patients were recruited and randomly divided into three groups: the mobilization group (CM; n = 15), the cervical and thoracic mobilization group (CTM; n = 15), and the thoracic mobilization group (TM; n = 15). Each intervention was performed in sets of three and repeated six times. Range of motion and pain were assessed pre- and post-intervention. The cervical range of motion was evaluated using a goniometer, and pain was evaluated using a visual analogue scale and pain thresholds of the suboccipital and upper trapezius muscles. Results: All groups showed an increase in range of motion post-intervention, but the increase in the CTM group was significantly greater than in the CM and TM groups (p < 0.05). Pain measured using the visual analogue scale decreased in all groups, but the decreases in the CM and CTM groups were significantly greater than in the TM group (p < 0.05). The pain thresholds of the suboccipital and upper trapezius muscles increased in all groups, but the increase in the CTM group was significantly greater than in the CM and TM groups (p < 0.05). Conclusion: Overall, our findings suggest that CTM may be more effective than CM or TM for improving cervical range of motion in the sagittal plane and pain in patients with FHP.

Objectives: The stability of crestal bone has been reported as a major factor in the success of dental implants. Implants can be placed in an equicrestal (crestal) or subcrestal position. The aim of this study was to evaluate the effect of implant depth placement on marginal bone loss. Materials and Methods: The study was created in a split-mouth design. Immediately after implant surgery, digital parallel radiographs were prepared and levels of bone were measured where marginal bone loss and bone level changes occurred. These measurements were repeated at 3-month and 6-month follow-up periods. Results: In this interventional study, 49 implants were evaluated in 18 patients. Primary bone height was not significant between the intervention and control groups in both mesial and distal aspects at 3 months and 6 months from the baseline. The mean marginal bone loss on the mesial side was 1.03 mm in the subcrestal group and 0.83 mm in the crestal group. In addition, mean marginal bone loss on the distal side was 0.88 mm and 0.81 mm in the subcrestal and crestal groups, respectively. Marginal bone loss was not significantly different between sexes, the maxilla or mandible, and in the anterior or posterior regions as well as between different lengths and diameters of implants. Conclusion: Based on the results of this study, there was no significant difference in terms of marginal bone loss between crestal and subcrestal implants.

Purpose: This study aimed to identify the effect of warm scarf on xerostomia and sore throat in postoperative colon cancer patients. Methods: A total of 40 participants with colon cancer who underwent colon cancer operation over 2hours were included from C University hospital in Seoul. The number of experimental group and control group is each 20 calculated by G*Power, and they were assigned by using nonequivalent control group no-synchronized design. In the experimental group, a warm scarf was applied to the neck for 120 minutes from entering the recovery room after the colorectal cancer surgery was completed. In the experimental group and the control group, xerostomia and sore throat were measured twice at 60-minute intervals. The degree of xerostomia was measured through the degree of wetness of the absorbent paper in mm, and the degree of sore throat was measured through the NRS (Numeral Rating Scale). Data were collected using self-administered questionnaires from August 2018 to September 2020 and were analyzed using IBM SPSS/WIN 21.0 Descriptive statistics, x² test, Fisher's exact test, t-test were used to determine the participant's characteristics. The effect of warm scarf on xerostomia and sore throat were separately estimated by Repeated Measures ANOVA. Results: The experimental group showed significant decrease of xerostomia and sore throat as time goes (p<.001). Conclusion: Results indicate that warm scarf on xerostomia and sore throat in postoperative colon cancer patients is helpful method for relieving side effect of tracheal intubation.

Fractures in the horse industry are challenging and a common cause of death in racehorses. To accelerate fracture healing, tissue engineering (TE) provides promising ways to regenerate bone tissues. This study aimed to evaluate the osteogenic effects of biphasic calcium phosphate collagen (BCPC) graft, bone morphogenetic protein 2 (BMP2), mesenchymal stem cell (MSC), and platelet-rich plasma (PRP) treatments in horses. Four thoroughbred horses were included in the study, and, in each horse, three cortical defects with a diameter of 5 mm and depth of 10 mm were formed in the third metacarpal bones (MC) and metatarsal bones (MT). The defects were randomly assigned to one of six treatment groups (saline, BCPC, BMP2, MSC, PRP, and control). Injections of saline, BMP2, PRP, or MSCs were made at 1, 3, and 5 weeks after defect surgery. Bone regeneration effects were assessed by radiography, quantitative computed tomography (QCT), micro-computed tomography (μCT), histopathological, and histomorphometric evaluation. The new bone ratio (%) in the histomorphometric evaluation was higher in the BMP2 group than in the control and saline groups. Radiographic and QCT values were significantly higher in the BCPC groups than in the other groups. QCT values of the BMP2 group were significantly higher than in the control and saline groups. The present study demonstrated that BCPC grafts were biologically safe and showed osteoconductivity in horses and the repeated injections of BMP2 without a carrier can be simple and promising TE factors for treating horses with bone fractures.

Purpose: The aim of this study was to evaluate image artifacts in the vicinity of dental implants in cone-beam computed tomography (CBCT) scans obtained with different spatial orientations, tube current levels, and metal artifact reduction algorithm (MAR) conditions. Materials and Methods: One dental implant and 2 tubes filled with a radiopaque solution were placed in the posterior region of a mandible using a surgical guide to ensure parallel alignment. CBCT scans were acquired with the mandible in 2 spatial orientations in relation to the X-ray projection plane (standard and modified) at 3 tube current levels: 5, 8, and 11 mA. CBCT scans were repeated without the implant and were reconstructed with and without MAR. The mean voxel and noise values of each tube were obtained and compared using multi-way analysis of variance and the Tukey test(α=0.05). Results: Mean voxel values were significantly higher and noise values were significantly lower in the modified orientation than in the standard orientation (P<0.05). MAR activation and tube current levels did not show significant differences in most cases of the modified spatial orientation and in the absence of the dental implant (P>0.05). Conclusion: Modifying the spatial orientation of the head increased brightness and reduced spatial orientation noise in adjacent regions of a dental implant, with no influence from the tube current level and MAR.

Objective: Flow diverting stents (FDS) are increasingly used for the treatment of intracranial aneurysms. While FDS can provide flow diversion of parent vessels, their high metal surface coverage can cause thromboembolism. Transcranial Doppler (TCD) emboli monitoring can be used to identify subclinical embolic phenomena after neurovascular procedures. Limited data exists regarding the use of TCDs for emboli monitoring in the periprocedural period after FDS placement. We evaluated the rate of positive TCDs microembolic signals and stroke after FDS deployment at our institution. Methods: We retrospectively evaluated 105 patients who underwent FDS treatment between 2012 and 2016 using the Pipeline stent (Medtronic, Minneapolis, MN, USA). Patients were pretreated with aspirin and clopidogrel. All patients were therapeutic on clopidogrel pre-operatively. TCD emboli monitoring was performed immediately after the procedure. Microembolic signals (mES) were classified as "positive" (<15 mES/hour) and "strongly positive" (>15 mES/hour). Clinical stroke rates were determined at 2-week and 6-month post-operatively. Results: A total of 132 intracranial aneurysms were treated in 105 patients. TCD emboli monitoring was "positive" in 11.4% (n=12) post-operatively and "strongly positive" in 4.8% (n=5). These positive cases were treated with heparin drips or modification of the antiplatelet regimen, and TCDs were repeated. Following medical management modifications, normalization of mES was achieved in 92% of cases. The overall stroke rates at 2-week and 6-months were 3.8% and 4.8%, respectively. Conclusions: TCD emboli monitoring may help early in the identification of thromboembolic events after flow diversion stenting. This allows for modification of medical therapy and, potentially, preventionf of escalation into post-operative strokes.

Since the first description of the possible utilization of the internal maxillary artery for bypass surgery, there are some reports of its use in aneurysm cases; however, there is no information about the possible advantages of this type of bypass for cerebral ischemic disease. We present a 77-year-old man with a history of diabetes, hypertension, systemic atherosclerosis, and two acute myocardial infarctions with left hemiparesis. Imaging studies reported total occlusion of the right internal carotid artery and 75% occlusion on the left side, with an old opercular infarction and repeated transient ischemic attacks in the right middle cerebral artery territory despite medical treatment. After a consensus, we decided to perform a bypass from the internal maxillary artery to the M2 segment of the middle cerebral artery using a radial artery graft. After performing the proximal anastomosis, the calculated graft's free flow was 216 ml/min. Subsequently, after completing the bypass, the patency was confirmed with fluorescein videoangiography and intraoperative Doppler. Postoperatively, imaging studies showed improvement in the perfusion values and the hemiparesis from 3/5 to 4+/5. The patient was discharged one week after the operation, with a modified Rankin scale of 1, without added deficits. The use of revascularization techniques in steno-occlusive disease indicates a select group of patients that may benefit from this procedure. In addition, internal maxillary artery bypass has provided a safe option for large areas of ischemia that cannot be supplied with a superficial temporal artery - middle cerebral artery bypass.
