Obliteration of Intercondylar Notch Mimicking Flexion-Extension Gap Imbalance in a Cruciate Retaining Total Knee Arthroplasty

Following total knee arthroplasty (TKA), the most frequent cause of extension deficit and limitation of range of motion in early postoperative period is related to improper tensioning of soft tissues and failure to balance extension and flexion gaps. If a cruciate retaining (CR) prosthesis is the planned implant, then attention should be given to balancing the posterior cruciate ligament (PCL), and any factor that alters this balance may also cause deterioration of knee balance in postoperative period. Here, we report on an unusual case referred from another hospital because of continuous pain and restriction of knee motion in early postoperative period following CR-designed TKA that was initially thought to be due to flexion-extension imbalance. However, during the revision procedure, extruded cement to the intercondylar notch was found to be both mechanically blocking terminal extension and limiting flexion by possible mechanism of irritation of the synovial nerve endings around the stretched anterior fibers of PCL during flexion. This case was successfully treated by removal of extruded cement from intercondylar notch to decompress PCL, polyethylene exchange, and secondary patellar resurfacing

Stress Analysis of Fiber-reinforced Maxillary Dentures Under Different Loadings

WOS: 000282429100006The aim of this study was to compare maxillary dentures having different reinforcing materials in terms of stress distribution under concentrated forces applied to anterior and posterior regions. For this purpose, stress analyses of finite element models of 3 mm thick maxillary denture-bone systems were performed by using ANSYS software. First, concentrated forces making various angles, such as 0 degrees, 15 degrees, 30 degrees, 45 degrees, 60 degrees, 75 degrees, and 90 degrees, with horizontal axis were applied to the anterior incisor and the posterior molar tooth regions of a maxillary denture without reinforcement material. The results show that the highest stress in critical zones occur at 75 degrees and 45 degrees angles, under loadings of 150N to molar and 75N to incisor region, respectively. Secondly, four different reinforcing materials including unidirectional and woven glass fibers, unidirectional carbon fibers, and alloyed chrome-cobalt fibers were placed in the denture in two different positions. Under vertical loadings, the sigma(x) stress distributions occurring in critical zones were investigated. It is concluded from the stress analyses that use of Cr-Co as a reinforcing material at the center of the maxillary denture gives the best results in terms of stress distribution and strength

Comparison of Stress Distributions of Dental Woven and Unidirectional Fiber-Reinforced Composite Crowns Under Different Loadings

WOS: 000271624900001The aim of this numerical study was to investigate and compare the stresses occurring in dental woven and unidirectional experimental fiber-reinforced composite (FRC) crowns under different thermal and singular force loading conditions. For this reason, finite element models of FRC crown and tooth systems were performed by using the ANSYS program. Stress analyses of the models were carried out under thermal loading conditions heated from 37 to 55 degrees C, cooled from 37 to 5 degrees C, and 450 N singular force loading conditions at different angles. The results indicated that high stresses occurred in both woven and unidirectional FRC crowns under horizontal loadings because of bending moment. Thermal stresses exhibited small values that did not cause any damage. It can also be concluded that since the stress component of sigma(z) in the woven type FRC was smaller than that of unidirectional type FRC, use of the woven FRC might be beneficial in comparison with the unidirectional composite

Oocyte pick up day mucus removal: Does it have a positive effect on pregnancy rates?

Aim: Mucus removal that would be done on the day of embryo transfer could be done on Oocyte pick up(OPU) day, and this practice might be related with better pregnancy rates since it is unlikely to cause uterine contractions during the embryo transfer. We compared the effects of mucus removal done on OPU day, transfer day or no removal at all on success rates of the treatment in three groups. Material and Method: We designed a prospective match control study. There were 131 cycles in which mucus removal was done on either OPU day or embryo transfer day (64 and 67 cycles respectively) and in 411 cycles mucus removal was not done, and these patients constituted the control group. Results: After mucus removal on OPU day, mucus removal on embryo transfer day and no mucus removal done at all, pregnancy rates were calculated as 40,6%, 29,9%, and 23,1% respectively and the difference among the groups was statistically significant (p=0,009). Discussion: Mucus removal on OPU day or on embryo transfer day improves pregnancy rates. It can be included in the routine practice, since it may potentially minimize cervical trauma and uterine contractions and thus improve success in IVF/ICSI treatments

Novel use of propranolol for management of pain in children with vertebral hemangioma: report of two cases

Introduction Vertebral hemangioma (VH) is an exceedingly rare neoplasm in pediatric population with less than 10 cases reported in the literature. It is usually asymptomatic in adults and diagnosed incidentally at radiographic investigations of other medical conditions. In this report, we describe two children who presented to our institution with severe back pain and were diagnosed with VH

Sonoelastographic Evaluation Of The Distal Femoral Cartilage In Patients With Anterior Cruciate Ligament Reconstruction

Objectives: This study aims to evaluate sonoelastographic properties of the distal femoral cartilage in patients with anterior cruciate ligament (ACL) reconstruction. Patients and methods: Demographic characteristics and operative data of 28 patients (27 males, 1 female; mean age 31.7 +/- 7.1 years; range 22 to 48 years) with unilateral ACL reconstruction were evaluated. Reconstruction was performed with patellar tendon graft in 22 patients (78.6%) and hamstring tendon graft in six patients (21.4%). Lysholm knee score was used for functional evaluation and chair stand test was used for lower extremity strength. Medial, intercondylar, and lateral distal femoral cartilage thicknesses of operated knees and healthy knees were measured with B-mode ultrasound, while strain ratios were measured with real time sonoelastography. Results: Postoperative mean follow-up duration was 20.4 +/- 9.8 months. Mean Lysholm knee and patient satisfaction scores were 88.0 +/- 8.5 and 8.2 +/- 1.8, respectively. Cartilage thicknesses were similar between operated and healthy knees (all p>0.05). Sonoelastographic strain ratio of medial distal femoral cartilage in operated knees was significantly higher (softer cartilage) (p=0.026). There was a negative correlation between strain ratio difference of medial cartilage of operated knees and lower extremity muscle strength (p=0.009, r=-0.487). Conclusion: While there was no difference for cartilage thickness between operated and healthy knees in B-mode ultrasound evaluation, detection of sonoelastographic strain ratio changes in medial distal femoral cartilage on the operated sides may indicate early structural changes following ACL reconstruction. Further studies are required to highlight the clinical effects of this relationship between the changes in cartilage structure and sonoelastography features.WoSScopu

The Effects of Smoking on Ultrasonographic Thickness and Elastosonographic Strain Ratio Measurements of Distal Femoral Cartilage

Although adverse effects of smoking on bone health are all well known, data on how smoking interacts with cartilage structure in otherwise healthy individuals remains conflicting. Here, we ascertain the effects of cigarette smoking on sonoelastographic properties of distal femoral cartilage in asymptomatic adults. Demographic characteristics and smoking habits (packets/year) of healthy volunteers were recorded. Medial, intercondylar, and lateral distal femoral cartilage thicknesses and strain ratios on the dominant extremity were measured with ultrasonography (US) and real time US elastography. A total of 88 subjects (71 M, 17 F; aged 18–56 years, N = 43 smokers and N = 45 nonsmokers) were evaluated. Mean amount of cigarette smoking was 10.3 ± 8.9 (1–45) packets/year. Medial, intercondylar and lateral cartilage were thicker in smokers than nonsmokers (p = 0.002, p = 0.017, and p = 0.004, respectively). Medial distal femoral cartilage strain ratio was lower in smokers (p = 0.003). The amount of smoking was positively correlated with cartilage thicknesses and negatively correlated with medial cartilage strain ratios (p < 0.05). Femoral cartilage is thicker in smokers but has less strain ratio representing harder cartilage on the medial side. Future studies are needed to understand how these structural changes in the knee cartilage should be interpreted with regard to the development of knee osteoarthritis in smokers.PubMedWoSScopu

Microencapsulation of Extra Virgin Olive Oil by Spray Drying: Effect of Wall Materials Composition, Process Conditions, and Emulsification Method

WOS: 000348130900005The objective of the study was to investigate the microencapsulation of extra virgin olive oil by spray drying to increase its stability and application area. The effects of homogenization rate, pump rate, i.e., flow rate of feeding emulsion and wall materials composition on physical and chemical properties of microencapsulated extra virgin olive oil powder (MEVOP) were evaluated. Maltodextrin (MD) and whey protein isolate (WPI) were used as wall materials and microencapsulation was carried out in a laboratory type spray dryer. The MD:WPI ratio as mixture variable and pump and homogenization rates as process variables were arranged through D-optimal combined design. The optimum wall materials composition and microencapsulation process conditions were determined as follows: 92 % (db) MD, 7 % (db) WPI, and 1 % (db) Tween 20 as wall materials composition and 17,500 rpm and 22 % homogenization and pump rates, respectively. The results showed that the wall materials composition was the most effective independent variables on physical properties in terms of moisture content, water activity, bulk and particle properties of powder as well as microencapsulation efficiency and oxidation stability of MEVOP during converting liquid extra virgin olive oil to powder form. The effects of emulsification methods in terms of rotor-stator and ultrasonic homogenization on physical and chemical properties of MEVOP were also comparatively investigated in this study. The MEVOP produced by ultrasonic homogenization had smaller particle size and lower microencapsulation efficiency than that of rotor-stator homogenization method. But microcapsules obtained by ultrasonic homogenization had better oxidative stability.TUBITAK-TOVAGTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [111 O 345]; Ege UniversityEge University; Council of Scientific Research ProjectsEge University [BAP 2010/MUH/011]; EBILTEMEge University [12-BIL-018]The authors acknowledge TUBITAK-TOVAG (Project Number: 111 O 345), Ege University, Council of Scientific Research Projects (Project Number: BAP 2010/MUH/011) and EBILTEM (Project Number: 12-BIL-018) for financial support
