Purpose: Oncoplastic surgery (OPS) has been developed with the aim of improving breast-conserving surgery (BCS) to provide better aesthetic and functional outcomes for breast cancer patients. We aimed to compare overall quality of life (QoL) and satisfaction with breast reconstruction in patients undergoing BCS and OPS using the Quality of Life Questionnaire Core 30 (QLQ-C30) and recently validated QLQ-Breast Reconstruction module (QLQ-BRECON23). Methods: A total of 87 patients were included in this single-center study between January 1, 2018 and December 31, 2021; 43 underwent OPS (49.4%) and 44 underwent BCS (50.6%). The data on patient, tumor, and treatment characteristics were obtained from the prospectively collected database at the hospital. QLQ-C30 and QLQ-BRECON23 were used to evaluate psychosocial well-being, fatigue symptoms, overall QoL, sexual well-being, sensation of the operative area, and satisfaction with the reconstruction. Results: According to QLQ-C30 evaluation there were significantly better outcomes for patients treated with OPS than BCS in terms of psychosocial well-being, fatigue symptoms, and overall QoL (P = 0.005, P = 0.016, and P = 0.004; respectively), according to QLQ-BRECON23 evaluation there were also significantly better outcomes in terms of sexual well-being, sensation of the operative area, and satisfaction of the reconstruction (P < 0.001, P = 0.002, and P < 0.001; respectively). Conclusion: We found that the overall QoL and satisfaction with breast reconstruction in patients undergoing OPS are better than those undergoing BCS. Our study is critical because it is the first study comparing OPS and BCS using the QLQ- BRECON23, which was recently validated.

PURPOSE. The storage conditions of impressions affect the dimensional accuracy of the impression materials. The aim of the study was to assess the effects of storage time on dimensional accuracy of five different impression materials by cone beam computed tomography (CBCT). MATERIALS AND METHODS. Polyether (Impregum), hydrocolloid (Hydrogum and Alginoplast), and silicone (Zetaflow and Honigum) impression materials were used for impressions taken from an acrylic master model. The impressions were poured and subjected to four different storage times: immediate use, and 1, 3, and 5 days of storage. Line 1 (between right and left first molar mesiobuccal cusp tips) and Line 2 (between right and left canine tips) were measured on a CBCT scanned model, and time dependent mean differences were analyzed by two-way univariate and Duncan's test (${\alpha}=.05$). RESULTS. For Line 1, the total mean difference of Impregum and Hydrogum were statistically different from Alginoplast (P<.05), while Zetaflow and Honigum had smaller discrepancies. Alginoplast resulted in more difference than the other impressions (P<.05). For Line 2, the total mean difference of Impregum was statistically different from the other impressions. Significant differences were observed in Line 1 and Line 2 for the different storage periods (P<.05). CONCLUSION. The dimensional accuracy of impression material is clinically acceptable if the impression material is stored in suitable conditions.

Study Design: Prospective comparative study. Purpose: To investigate the efficacy of gluteal trigger point (TP) injections with prilocaine in patients with lumbosacral radiculopathy complaining of gluteal pain. Overview of Literature: TP injections can be performed using several anesthetic agents, primarily lidocaine and prilocaine. While several studies have used lidocaine, few have used prilocaine. Methods: A total of 65 patients who presented at the polyclinic with complaints of lower back pain with lumbar disc herniation (based on physical examination and magnetic resonance imaging) and TPs in the gluteal region were included in this prospective comparative study. Group 1 comprised 30 patients who were given TP injections, a home exercise program, and oral medications, and group 2 comprised 35 patients who were only treated with a home exercise program and oral medications. The patients’ demographic data, Oswestry Disability Index (ODI) scores, and Visual Analog Scale (VAS) scores were recorded, and these data were evaluated at 1- and 3-month follow-ups. Results: The ODI and VAS scores of both groups significantly decreased initially and at the follow-up examinations, but the decreases were more marked in group 1. Conclusions: We obtained better results with TP injections than only a home exercise program and oral medications in patients with radiculopathy and TPs in the gluteal region.

PURPOSE. The purpose of this study was to evaluate and compare three polishing systems on the surface roughness and phase transformation of monolithic zirconia. MATERIALS AND METHODS. 100 disk shaped specimens (10 mm diameter, 3 mm thickness) were fabricated from monolithic zirconia blocks. 20 specimens were left as a control group and remaining specimens were grinded by diamond bur to simulate the occlusal adjustments. Grinded specimens were randomly divided into 4 groups: group G (no polishing), group M (Meisinger, zirconia polishing kit), group E (EVE Diacera, zirconia polishing kit), and group P (EVE Diapol, porcelain polishing kit). Surface roughness was measured with profilometer and surface topography was observed with SEM. XRD analysis was performed to investigate the phase transformation. Statistical analysis was performed with one-way ANOVA and Tukey’s post hoc tests at a significance level of P=.05. RESULTS. All polishing groups showed a smoother surface than group G. Among 3 polishing systems, group M and group E exhibited a smoother surface than the group P. However, no significant differences were observed between group M and group E (P˃.05). Grinding and polishing did not cause phase transformations in zirconia specimens. CONCLUSION. Zirconia polishing systems created a smoother surface on zirconia than the porcelain polishing system. Phase transformation did not occur during the polishing procedure.

Purpose: Ankaferd Blood Stopper (ABS) is an herbal extract attained from 5 different plants. It has the therapeutic potential to be used for the management of external hemorrhage and controlling gastrointestinal bleedings. To date, the safety of ABS for intraperitoneal usage is not clear. In this study, we investigated the effectiveness and safety of using intraperitoneal ABS in an experimental peritoneal adhesion model. Methods: Twenty-four male Wistar Albino rats were used in the study. The rats were randomly divided into 3 groups: saline, ABS, and control. On the 10th day, all rats were euthanized. The adhesions were evaluated by Nair’s macroscopic adhesion classification, and pathologically evaluated with Zühlke’s microscopic adhesion classification. Results: A macroscopic and microscopic comparison between the ABS and saline groups did not show any differences but both the ABS and saline groups were superior when compared to the control group. Conclusion: ABS was found equally effective with saline on the abdominal adhesions and to no effect on postoperative adhesion formation.
