Effects of Hyperglycemia on Angiogenesis in Human Placental Endothelial Cells.

The placenta is a temporary organ that provides communication between the mother and fetus. Maternal diabetes and abnormal placental angiogenesis may be linked. We investigated the angiogenesis mechanism resulting from VEGF and glucose stimulation in PECs obtained from human term placenta. Immunohistochemistry was performed to characterize PECs obtained from human term placenta. D-glucose was added to the medium containing PECs to establish normoglycemic and hyperglycemic conditions. The expression levels of VEGF, VEGFR-1 and VEGFR-2 genes and proteins in PECs from the control and experimental groups were analyzed by RT-PCR and Western blotting, respectively. With 48-hours incubation, gene expressions increased due to hyperglycemia, while protein levels increased due to the combined effect of VEGF and hyperglycemia. While VEGFR-2 gene expression and protein amounts increased in 24-hours due to the combined effect of VEGF and hyperglycemia, the effect of VEGF stimulation and glucose level on VEGFR-2 decreased in 48-hour incubation with time. VEGF, VEGFR-1 and VEGFR-2 genes and proteins were affected by hyperglycemic conditions in PECs. Hyperglycemia occurring in various conditions such as gestational diabetes mellitus and diabetes mellitus may affect VEGF, VEGFR-1 and VEGFR-2 genes and proteins of PECs derived from human term placenta.

Long-term outcomes of first metatarsophalangeal hemiarthroplasty for hallux rigidus.

Hallux rigidus (HR) is arthritis of the first metatarsophalangeal joint.First metatarsophalangeal joint hemiarthroplasty surgery is one of the treatment options for end stage hallux rigidus.The aim of this study is to evaluate the long-term outcomes of hemiarthroplasty of the first MTPJ with a metallic implant in patients with end-stage HR. Patients who underwent hemiarthroplasty surgery with the diagnosis of HR were included in the study. Self-Administered Foot Evaluation Questionnaire (SAFE-Q) and Foot and Ankle Disability Index (FADI) scores were used in pre-operative and post-operative final follow-ups to evaluate the clinical status of the patients. Post-operative 1st metatarsophalangeal joint range of motion was measured and recorded separately for each patient. The intra-hospital and follow-up complications and revision surgeries of the patients were recorded. Thirty-five patients with a mean follow-up of 8.1 years were included in the study. There was a statistically significant positive change in both FADI and SAFE-Q scores compared to the pre-operative process(p = 0.0001). The average dorsiflexion angle at the final follow-up was 22.0 ± 8.2. Thus, it was determined that the 5-year and 8-year survival rates of patients in this study were 97.1% and 87.8%, respectively. In conclusion, the long-term results show that the use of hemiarthroplasty in the treatment of end-stage HR leads to high patient satisfaction, increased range of motion and a high survival rate.

Local curvature mismatch may worsen the midterm functional outcomes of osteochondral allograft transplantation.

PURPOSE: This study aimed to determine the magnitude of local curvature matching in the sagittal plane between an implanted graft and the condylar region receiving the graft and to analyze its effect on clinical outcomes in patients undergoing osteochondral allograft transplantation (OCA). METHODS: Patients who underwent knee OCA between 2016 and 2019 without circumferential step-off and were matched with a donor in accordance with the conventional matching process were included. The magnitude of donor-host local curvature matching was measured using postoperative sagittal magnetic resonance imaging data with Syngo (Siemens Medical Solutions, Forchheim, Germany) and GeoGebra (GeoGebra GmbH, Linz, AU) software. In addition to radiological evaluation, ROC analysis was performed to compare the patient-reported outcome measures (PROMs) obtained during the 2-year follow-up period among the patients in the SagA group, who had a graft match in the sagittal plane; SagB group, who had low convexity of the graft in the sagittal plane; and SagC group, who had high convexity of the graft in the sagittal plane in accordance with the determined indices. RESULTS: The study included 27 patients who fulfilled the inclusion criteria, and the mean clinical scores of the SagC group were not statistically significantly higher than those of the other groups at any timepoint during the follow-up. The mean Tegner, IKDC, total KOOS and SF-12 physical and mental health scores of the SagC group were lower than those of the other two groups at various follow-up time points, particularly at month 24 (p < 0.05). There were no significant differences between the SagA and SagB groups in the PROMs at any of the follow-up time points (n.s.). The significant differences observed between the SagC group and the other groups in the mean KOOS scores for function in daily living and function in sport and recreation were also observed between the SagA and SagB groups at the follow-ups (p < 0.05). CONCLUSION: During OCA, a local curvature mismatch between the donor and the host involving large graft convexity may have a negative impact on midterm clinical outcomes. A preoperative analysis of the convexity relationship between the defect site and the graft region in the hemicondylar allograft to be used may enhance donor-host matching. The local analysis method described in the current study may also facilitate graft supply by ensuring donor-host matching without condyle-side and size matching. LEVEL OF EVIDENCE: III.

Introduction of a novel quantitative scoring system for acanthosis nigricans and its validation in a pilot study.

Inconsistent data exist regarding the diagnostic value of acanthosis nigricans (AN) or skin tags as clinical markers for obesity or diabetes. In an outpatient department-based prospective study, we designed a scoring for AN severity (SCANS) to evaluate AN and skin tags, their correlation with obesity or diabetes. Quantification of AN in six anatomic sites, in consideration of the affected skin surface areas, texture changes, number of skin tags, leads to a total severity score between 0 and 46. Among 336 adult patients (aged ≥18 years) with AN, a higher BMI was associated with AN (r = 0.299, P < .001), but not with diabetes (P = .43), as compared with 243 age- and sex-matched controls without AN. Among nondiabetics, AN scores were significantly correlated with waist circumference (r = 0.131, P = .024) and total cholesterol levels (r = 0.155, P = .04). Skin tags alone in the absence of AN were not associated with obesity (P = .333) or diabetes (P = .164). The total AN scores were positively correlated with the presence of skin tags (r = 0.132, P < .001), and the involvement of anterior neck (r = 0.668, P < .001) and axilla (r = 0.793, P < .001). Knuckles and groins were unaffected in our series. Our results indicate that combination of AN with skin tags can be used as clinical marker for obesity, but not for diabetes. Large-scale studies on patients of different ethnic background are required to further validate our proposed scoring.

Radiographs are not sufficient for evaluation of component fit in subtle knee pain after total knee arthroplasty.

PURPOSE: To determine the component fit by radiography or computed tomography after total knee arthroplasty and the relation of imaging with clinical examination of residual knee pain. METHODS: The study was conducted in 172 patients with residual knee pain after total knee arthroplasty. The patients were examined to determine whether they experienced pain upon palpation at nine regions surrounding the tibial and femoral components, and the results were noted. The Knee Society Clinical Rating System and The Western Ontario and McMaster Universities Arthritis Index pain scale score forms were completed for all patients. Radiologic evaluation was performed using computed tomography and anteroposterior, lateral, and oblique radiographs to determine component overhang/underhang status at these nine regions. Overhang, underhang, and cortical fit groups were created based on the position of the component at the bone margin. A statistical relationship was sought between the clinical scores and the values measured to determine which imaging method showed the best correlation with clinical scores. Consistency of CT and Rx measurements was compared using the McNemar-Bowker test. Comparisons between groups were made using Student's t test for normally distributed data, and the Mann-Whitney U test. RESULTS: Computed tomography and radiographic measurements were similar in the medial, anterior, and lateral tibial regions. However, no similarities were observed in the anteromedial, anterolateral, posteromedial, and posterolateral tibial regions, and in the distal-medial and distal-lateral aspects of the femur. Statistical relationships among decreased clinical scores, pain with palpation, and the presence of overhang/underhang were only observed in the medial tibial region for imaging using radiography. A statistically significant relationship was observed in the medial, posteromedial, and posterolateral tibial regions, and in the distal-medial region of the femur for imaging based on computed tomography. CONCLUSIONS: Radiography could only aid in assessing the component fit in the anteromedial, medial, and lateral regions of the tibia in patients with residual knee pain following knee arthroplasty, but it was not sufficient in comparison with computed tomography in six other regions. LEVEL OF EVIDENCE: Prospective study, level of evidence II.

Ultrasound processing of verjuice (unripe grape juice) vinegar: effect on bioactive compounds, sensory properties, microbiological quality and anticarcinogenic activity.

Verjuice is one of the alternative fruit juices recently obtained from unripe grapes. In this study, the aim was primarily to optimize the process conditions for the enrichment of bioactive components in verjuice vinegar with ultrasound treatment. For this purpose, ultrasound treatment was applied to vinegar samples at different times (2, 4, 6, 8 and 10 min), different amplitudes (60%, 65%, 70%, 75% and 80%) and 26 kHz frequency. Total phenolic content (TPC), total flavonoid content (TFC), total antioxidant capacity (1,1-diphenyl-2-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC) were evaluated for optimization (response surface methodology (RSM) and genetic algorithm (GA)) of process conditions. The sensory properties, microbiological quality and anticarcinogenic activity were then evaluated for the ultrasound-treated verjuice vinegar (UVV) (9.4 min and 68.7 amplitude result of RSM), traditional verjuice vinegar and pasteurized verjuice vinegar samples obtained from the optimization. At the end of the RSM optimization, CUPRAC (464.44 mg TEAC/mL), DPPH (0.694 mg TEAC/mL), TFC (70.85 mg CE/mL) and TPC (12.22 mg GAE/mL) were determined. RSM and GA results were found to be approximately the same. Analysis results showed that ultrasound-treated verjuice vinegar was enriched bioactive components compared to other samples. Verjuice vinegar showed anticarcinogenic effects. The UVV sample was generally appreciated in sensory evaluation. As a result, ultrasound treatment of verjuice vinegar was found to be successful.

Nineteen-year retrospective evaluation of pemphigus in a single dermatology centre in Istanbul, Turkey.

INTRODUCTION: Pemphigus is an autoimmune intra-epidermal bullous disease of the skin and mucosae. AIM: To retrospectively evaluate the course, prognosis and clinical features of pemphigus. MATERIAL AND METHODS: The files of 196 pemphigus patients admitted to our clinic between December 1995 and December 2014 were collected and analysed. RESULTS: The male to female ratio among patients was 1 : 1.88. Pemphigus vulgaris (PV) was the most common clinical variant observed in 175 (89.3%) of the patients, followed by pemphigus foliaceus (PF) in 14 (7.1%) of the patients. The mean patient age at disease onset was 50 years. PV presented itself as skin lesions in 55 (31.4%) of the patients and as oral mucosa lesions in 120 (68.6%) of the patients. Complete remission and treatment withdrawal were obtained in 112 (57.1%) of the patients, for a mean period of 2.91 ±2.66 years (range: 4 months to 13 years). The mortality rate was 6%, and relapse occurred in 16 (14.3%) of the patients for a mean relapse period of 2.15 ±1.88 years (range: 6 months to 7 years). Mucocutaneous pemphigus (MCP) was the major clinical pattern observed in 96 (49%) of the patients. CONCLUSIONS: Within our study population, pemphigus predominately affected females, and the most common clinical variant was PV, a subtype that frequently occurs in middle-aged individuals. MCP was the most common clinical pattern. Although MCP and higher doses of corticosteroids were needed to control pemphigus, they did not seem to influence the prognosis.

Definition of a Novel Proximal Femur Classification in the Sagittal Plane According to the Femur Morphometric Analysis.

BACKGROUND: Studies on prosthesis positioning and implant design in total hip arthroplasty (THA) have generally focused on the anatomy of the proximal femur in the coronal plane. The aim of this study was to investigate the proximal femur morphology in the sagittal plane to provide better positioning of the femoral component in THA and contribute to the determination of proximal femur morphology through possible outcomes that can be shown also by considering the sagittal plane in the selection and design of the femoral component. METHODS: Computerized tomography scans were obtained from 270 femoral bones belonging to adult skeletons, followed by 3D reconstruction using Leonardo Dr/Dsa Va30a software (Siemens, Erlangen, Germany) and measurements. Canal widths were measured in the coronal and sagittal planes at the lesser trochanter (LT) level, at 20 millimeters proximal to the LT(LT+20) and at various levels distal to the lesser trochanter in 25 mm jumps up to 200 mm from the lesser trochanter. RESULTS: The average width was wider at the level of the lesser trochanter and all points distal to it in the sagittal plane compared to the coronal plane except LT-200 mm. At each levels from LT-25 to LT-175, the differences were statistically significant (P < .05). The ratio of the femoral width at the lesser trochanter level to the width 50 mm distal to the LT was stated as the most prevalent one, and a novel classification in the sagittal plane was developed in accordance with these findings. CONCLUSION: A novel and simple classification in the sagittal plane was developed based on the findings of this study, and this classification may improve the accuracy, validity, and reliability of femoral stem fixation in total hip arthroplasty.

Does inflammatory joint diseases affect the accuracy of infection biomarkers in patients with periprosthetic joint infections? A prospective comparative reliability study.

BACKGROUND: The diagnosis of periprosthetic joint infections (PJI) in patients with inflammatory joint diseases (IJD) could be challenging. Several tests used for diagnosing PJI may be inaccurate due to baseline inflammatory characteristics of such diseases. We aimed to evaluate the accuracy of several infection biomarkers, in a specific subgroup of patients with PJI and IJD. METHODS: From January 2014 to August 2017, patients with resisting pain at the relevant site, following total knee arthroplasty were evaluated prospectively. A total of 38 patients were undergone revision arthroplasty. Patients were categorized in terms of MSIS criteria: Patients with PJI (Group 1, n = 17) and patients without PJI (Group 2, n = 21). Serum ESR, CRP, Procalcitonin, synovial cell count, percentage of neutrophils in synovial fluid, synovial CRP, Lactoferrin, ELA-2, Thiol - Disulphide levels, BPI and the Alpha defensin test results were obtained. The results of two groups were compared and the diagnostic accuracy of each variable was evaluated. RESULTS: There were 22 women, 16 men with a mean age of 67.8 ± 6.9 years. The differences were significant in all evaluated biomarkers in terms of PJI (p values of all biomarker were <0.001). Alpha defensin, Lactoferrin, ELA-2, BPI, Procalcitonin and synovial CRP were the most accurate tests with area under curve >0.90. CONCLUSIONS: Our results demonstrated that IJD may not affect the accuracy of infection biomarkers in patients with PJI. Alpha defensin test, Lactoferrin, ELA-2, BPI, Procalcitonin and synovial CRP can be used in the diagnosis of PJI in patients with IJD.

Sonoelastography of the knee joint.

Magnetic resonance imaging (MRI) is generally the preferred method for assessing lesions of the knee cartilage and subchondral bone. There have been a few cartilage imaging studies using real-time elastosonography (RTE), which has increased in importance and range of use in recent years. The aim of this cadaveric study was to assess the efficacy of a new diagnostic method combining USG and RTE and also to perform intra-articular examinations together with arthroscopy. A total of 12 fresh unpaired human knees were examined. The laparoscopic ultrasound transducer was deployed using standard anteromedial and anterolateral arthroscopic portals. Iatrogenic defects were examined using mosaicplasty tools in healthy-looking areas of cartilage, and strain in those areas was measured using RTE. The median strain value of the pathological femoral cartilage region was significantly higher than that of the normal cartilage region (1.23 [0.71-2.24] vs. 0.01 [0.01-0.01], P = 0.002, respectively). Arthroscopic study of cartilage using RTE can be a guide for orthopedic surgeons and use of intra-articular probes could be universalized. Clin. Anat. 32:99-104, 2019. © 2018 Wiley Periodicals, Inc.

Fixed-bearing unicompartmental knee arthroplasty tolerates higher variance in tibial implant rotation than mobile-bearing designs.

BACKGROUND: UKA necessitates a learning period. From this point of view, it would be logical to prefer the design that tolerates suboptimal tibial rotations better, especially for inexperienced surgeons. The aim of this study was to evaluate and compare the clinical and radiological results of mobile-bearing and fix-bearing UKA designs in case of suboptimal tibial rotations. METHODS: A retrospective case-control evaluation was made of all the patients with medial compartment osteoarthritis, treated between January 2011 and January 2015. 324 patients ideal femoral rotation were enrolled in the study. 153 patients (Group 1) were treated with fix-bearing design with a mean 28.8 ± 11.3 month follow-up and 171 patients (Group 2) were treated with mobile-bearing design with a 31 ± 14.3 month follow-up. Each patient in groups was subdivided into (A): optimal tibial rotation, (B): external rotation of tibial component > 5°, (C): internal rotation of tibial component > 5° subgroups. WOMAC and KSS scores of each patient at preoperative and postoperative final control were compared between groups and subgroups. RESULTS: No significant differences were determined between the groups in terms of mean follow-up time (p = 0.0612), preoperative WOMAC, and KSS scores (p = 0.754 and p = 0.832, respectively). No significant differences were determined between subgroups 1A and 2A in terms of WOMAC and KSS scores at the final evaluation (p = 0.314 and p = 0.546, respectively). A significant difference was determined between subgroups 1B and 2B in terms of WOMAC and KSS scores (p = 0.021 and p = 0.012, respectively). In addition, the difference between subgroups 1C and 2C was significant (p = 0.047 and p = 0.034, respectively) at the final evaluation. CONCLUSION: Both mobile- and fix-bearing designs are beneficial in the treatment of medial compartment osteoarthritis of the knee. However, in case of both tibial internal or external suboptimal tibial rotations, fix-bearing design have better results compared to mobile-bearing design. STUDY DESIGN: Level III retrospective comparative clinical study.

Posterolateral overhang affects patient quality of life after total knee arthroplasty.

PURPOSE: To investigate the appropriate mediolateral placement of symmetrical tibial components and the amount of overhang expected from the posterolateral of tibial components implanted to give ideal coverage and the subsequent incidence of residual knee pain and reduction in functional capacity. METHOD: A retrospective evaluation was made of 146 consecutive total knee arthroplasties. The posterolateral overhang, rotational alignment and coverage of the tibial component were measured on a post-operative CT scan and the effect of posterolateral overhang on clinical outcomes was analysed 3 years after surgery. RESULTS: Complaints of local pain in the posterolateral corner were determined in 76 (52.1%) patients. At the Posterolateral corner, overhang was determined in 111 (76%) patients, in the cortical border in 11 (7.6%) patients and underhang in 24 (16.4%) patients. In 71 (48.6%) patients, pain was determined together with oversize and in the evaluation of the overhang of the tibial component in the posterolateral region and the rotation status, there was determined to be overhang in 75 (96.2%) patients where the tibial component was placed in ideal rotation, in 25 (100%) where placement was in external rotation and in 11 (25.6%) where placement was in internal rotation. The mean KSS, KSS-F and WOMAC-P scores were 83.9 ± 6.3, 83.3 ± 7.8 and 4.6 ± 2.9, respectively, in those with posterolateral overhang of the tibial component .The mean KSS, KSS-F and WOMAC-P scores were 86.6 ± 8.4, 89.5 ± 7.8 and 2.8 ± 2.1, respectively, in those with no overhang and the difference was determined to be statistically significant. The amount of overhang was determined as mean 3.6 ± 2.0 mm in those with posterolateral pain and 0.02 ± 3.4 mm in those without pain and the difference was statistically significant. CONCLUSIONS: This study demonstrated that overhang in the posterolateral region is surprisingly high and negatively affects the clinical results following TKA, thereby presenting a danger to the success of TKA. The risk of posterolateral oversizing can increase with placement of the tibial component in external rotation.

Can adnexal torsion be predicted by measuring plasma heat shock protein 70 level? An experimental study.

OBJECTIVE: To investigate the effect of adnexal torsion on the plasma heat shock protein 70 level and to determine whether plasma heat shock protein 70 can be used in the adnexal torsion diagnosis. MATERIALS AND METHODS: Twenty-one nulligravid 3-month-old female Wistar albino rats were randomly and equally allocated into three groups: study group (ovarian torsion) (n = 7), laparotomy group (sham operation) (n = 7) and control group (received no special treatment) (n = 7). Ovarian torsion model was created by twisting the right adnexa two times around its pedicle and fixing over the lateral pelvis with 6.0 polyglactin absorbable surgical suture. Blood was sampled before and 12 h after operation to assess plasma heat shock protein 70 level. RESULTS: In the study group, the mean plasma heat shock protein 70 level was significantly higher than that in the laparotomy and control groups (1.75 ± 0.25), (1.16 ± 0.99), (1.19 ± 0.11) ng/ml, respectively, P = 0.001), following 12 h of ovarian torsion. CONCLUSION: A significant increase in plasma heat shock protein 70 level in the study group indicates that plasma heat shock protein 70 level could be used as a serum marker in the early detection of adnexal torsion. However, further clinical and experimental studies of a larger size are required.

Plantar Fibromatosis in a Mentally Challenged Man Treated with Intralesional Corticosteroids.

A 21-year-old mentally challenged man presented with a fixed plaque lesion on the right foot, which had been present for 10 years. Dermatologic examination revealed an erythematous, painful, firm, fixed plaque-nodular lesion on the plantar aspect of the right foot (Figure 1A). Nothing of distinction was noted from his family history or his laboratory tests. An incisional biopsy revealed parallel, regular bundles composed of uniform, plump spindle cells. Thin collagen fibers were seen in contact with and located between the spindle cells. This mass was separated from the surrounding soft tissue by an irregular, unclear border (Figure 2A). Immunohistochemically, the spindle cells showed diffuse, strong reactivity to vimentin (Figure 2B) and smooth muscle actin.

Alternatives to surgical approach for giant spinal schwannomas.

OBJECTIVE: To review the diagnoses and surgical approach characteristics of giant spinal schwannomas (GSS) patients. METHODS: We reviewed the preoperative and postoperative radiological and clinical data, and the surgical aspects of 18 GSS patients who underwent surgery in the Department of Neurosurgery, Umraniye Teaching Hospital and Research State Hospital, Istanbul, Turkey between January 2008 and December 2013. RESULTS: There were 15 (83.3%) female and 3 (16.6%) male patients. The age range was 16-70 years (average: 45.8). Average symptom duration was 1.5 months (range: 1-48). There was local pain in 15 cases, and radicular pain in 6 cases. The GSSs were most frequently located in the lumbosacral area (11 cases, 61.1%). An extraforaminal surgical approach was employed in 7 cases, a posterior approach was employed in 6 cases, a combined anterior transabdominal and posterior approach was employed in 2 cases, a combined posterior and extraforaminal approach was employed in 2 cases, and a retroperitoneal approach was applied in one case. The tumors were completely excised in all cases. The mean follow-up period was 38.5 months (range: 20-68). CONCLUSION: Giant spinal schwannomas exhibit unique diagnostic and surgical factors. The selection of an appropriate approach significantly influences the success of the treatment.

Evaluation of vitamin C and vitamin E for prevention of postoperative adhesion: a rat uterine horn model study.

AIM: To investigate the effectiveness of intraperitoneal vitamin C (VC) and vitamin E (VE) in the prevention of postoperative adhesion formation in a rat uterine horn model. METHODS: Twenty-eight Wistar albino rats were divided into four groups in which: control group, the abdomen was opened and closed without any intervention; adhesion group, a 2-cm linear incision was performed on the uterine horn and closed; VC group, VC was administrated i.p., and 15 min later a 2-cm incision was performed on the uterine horn and closed; and VE group, VE was administrated i.p., and 15 min later a 2-cm incision was performed on the uterine horn and closed. Re-laparotomy was performed 15 days later. Right uterine horn adhesions were evaluated according to macromorphological characteristics and tissue sections were further examined for fibrosis, angiogenesis and vascular endothelial growth factor (VEGF), type I collagen and malondialdehyde (MDA) scoring. Kruskal-Wallis anova and Mann-Whitney U-test were utilized for statistical analysis. RESULTS: Adhesion area and also strength were significantly lower in the VC group and the VE group compared with the adhesion group. Fibrosis and angiogenesis scores were observed to be significantly higher in the adhesion group compared with the VC group and the VE group. MDA and VEGF immunoreactivity were also found to be significantly lower in the VC group and the VE group compared with the adhesion group. However, there was no significant difference between the VC group and the VE group with respect to all the above parameters. CONCLUSION: Administration of VC or VE i.p. was observed to be effective in the prevention of postoperative adhesion formation in an experimental model.

Comparison of pre-procedural anxiety and depression scores for patients undergoing chorion villus sampling and amniocentesis: An alternative perspective on prenatal invasive techniques.

OBJECTIVE: To compare the pre-procedural anxiety and depression levels of patients undergoing chorion villus sampling (CVS) and amniocentesis (AC). METHODS: Patients referred to our department for fetal karyotype analysis with a positive first or second trimester screening test for aneuploidy between January 2013 to June 2015 were included. CVS and AC procedures were performed in patients with gestation periods of between 11-14 and 16-20 weeks, respectively. Anxiety was evaluated using the Spielberger State-Trait Anxiety Inventory (STAI), and depression was assessed using the Beck Depression Inventory II (BDI-II). RESULTS: A total of 1,400 patients were included. Compared to first trimester controls, patients undergoing CVS had significantly higher STAI-state and BDI-II results. Likewise, patients undergoing AC had higher STAI-state and BDI-II scores than controls in the second trimester. In terms of STAI-trait results, no difference was found between the groups. Our results also showed that, compared to AC group, patients undergoing CVS had similar STAI-state, STAI-trait and but higher BDI-II scores. CONCLUSION: We conclude that evaluating the stress and depression levels of these patients should be one of the routine procedures in pregnancy follow-up.

Intravaginal misoprostol alone versus intravaginal misoprostol and extraamniotic Foley catheter for second trimester pregnancy termination: an observational study.

BACKGROUND: No systematic empirical research exists addressing the question of optimal pregnancy termination method in second trimester pregnancies. OBJECTIVES: The purpose of this study was to determine the efficacy and safety of intravaginal misoprostol and extraamniotic Foley catheter combination for second trimester pregnancy termination. METHODS: A single center observational study was conducted in a total of 91 pregnancies. Women who met the termination of pregnancy criteria due to feto-maternal indications between 13 to 26 gestational weeks were included into the study. Study participants received intravaginal misoprostol in combination with Foley catheter (n = 46) or intravaginal misoprostol alone (n = 45). RESULTS: The efficacy of intravaginal misoprostol and Foley catheter insertion combination was comparable to that of intravaginal misoprostol alone in terms of time to abortion/birth [median (95% Confidential Interval [95% CI]): 14.33 (11.33-17.25) hours and 12.08 (9.50-15.33) hours, respectively Hazard Ratio: 0.73, 95% CI: 0.47 to 1.12, p = 0.14 (log-rank)]. The only serious maternal event was uterine rupture observed in one woman in Foley combination group. CONCLUSION: The combination of intravaginal misoprostol and extraamniotic Foley catheter for second trimester pregnancy termination does not provide additional efficacy.

Comparison of Biomechanical Behaviors of Different Designs and Configurations of Titanium and Zirconium Dental Implants With Finite Elements Analysis in Anterior Maxilla.

Finite element analysis assists in the understanding of the biomechanical behavior of implants with different designs and material characteristics. Through this analysis, this study aimed to compare the biomechanical behaviors of different designs and configurations of titanium (tapered or cylindric) and zirconia dental implants in the edentulous anterior maxilla. Three-dimensional models of the edentulous maxilla, dental implants, and prosthetic structures were modeled, and different loading conditions were applied to simulate realistic conditions. A total of 6 different models were evaluated: the model (M1) in which tapered implants were located bilaterally in the central canine, the model (M2) in which tapered implants were located bilaterally in the lateral canine, the model (M3) in which cylindric implants were located bilaterally in the central canine, the model (M4) in which cylindric implants were located bilaterally in the lateral canine, the model (M5) in which zirconia implants were located bilaterally in the central canine, and the model (M6) in which zirconia implants were located bilaterally in the lateral canine. Maximum tensile and compressive stress values were recorded at M4 under vertical loading and at M6 under oblique loading, whereas minimum stress values were recorded at M1 under all loading conditions. Maximum von Mises stress values under vertical and oblique loading conditions were observed at M3 and M4, while the minimum stress was observed at M1 and M2. In conclusion, zirconia implants may present a biomechanically convenient and esthetic alternative treatment option in edentulous anterior maxilla rehabilitation compared with tapered and cylindric implants.
