Objective: The aim of study is to evaluate the results of deployment of Percutaneous Radiological Gastrostomy (PRG), which is a good alternative to Surgical Gastrostomy (SG), with transoral approach in cases where Percutaneous Endoscopic Gastrostomy (PEG) is contraindicated, difficult or unsuccessful, in patients with high risk of American Society of Anesthesiologists with four scores. In addition, we aimed to demonstrate the advantages of mushroom pull type catheters over push type gastrostomy catheters. Methods: This retrospective study included a total of 40 patients (18 females and 22 males) aged 21–92 years who underwent PRG with the antegrade transoral approach. PRG was performed by retrograde passing through the esophagus or snaring the guidewire from the stomach and taking out of the anterior abdominal wall. Patients’ demographic data, indications for PRG, procedural outcomes and complications were screened and recorded. Results: PRG was performed in 39 of 40 patients included in the study. Technical success rate was 97.5%. Procedure-dependent major complications such as death, aspiration, colon perforation, and deep abscess were not observed. Aspiration occurred in the first patient during the first feeding on the day after the procedure. Major complication rate was 2.5%. The total minor complication rate was 17.5% in 7 patients; parastomal leakage in 2 patients (5%), skin rash and infection in 3 (7.5%) patients, minor bleeding in 2 (5%) patients with oropharynx cancer, minimal bleeding from the gastrostomy catheter 1 week after the procedure in 1 (2.5%) patient. None of the cases had buried buffer. Tube functionality was preserved in all patients without any damage. Conclusion: Mushroom tip (pull type) gastrostomy catheter is a safe treatment method for patients requiring prolonged feeding because of wide diameter, endurance, long staying opening duration, less excessive dilatation and parastomal leakage, and no need for gastropexy. Lower cost and easier access are advantageous for mushroom tip pull type catheters compared to push type gastrostomy catheters in our country. The less invasive PRG is an alternative option in patients who are difficult to administer PEG, are at high anesthesia risk and cannot be sedated. Advances in knowledge: This article is valuable in terms of its contribution to develop an alternative radiological method for the deployment of gastrostomy tubes in medical difficult patients. This method has shortened the duration of the procedure and increased the success rate in patients with difficulty in transition from the stomach to the esophagus or with difficulty in the upper gastrointestinal tract. Mushroom tip catheters can be placed successfully by radiological methods.

Abstract Objective: The present study explains the success and failure of dental implant diameter on the efficiency of fatigue by conducting a systematic review analysis. Methods: An extensive literature search was conducted to carry out systematic review using different scholarly platforms and libraries. A total of 12 studies published within the past 20-year time (1999-2019) were included following the inclusion and exclusion criteria based on the PRISMA guidelines. Additionally, the study outcomes were evaluated to determine their perceptions regarding the role of dental implant diameter in influencing the implant’s fatigue performance. Results: The implant diameter can be categorized into wide diameter (5-6 mm), regular diameter (3.75-4 mm), and small/narrow diameter (3-3.4 mm). The narrow diameter implants are indicated through thin alveolar ridges and mesiodistal spaces (less than 7 mm). The implants with narrow diameter would offer greater risk of fatigue failure for clinical situations with significant functional loading. No significant differences were found either in success or failure of dental implant diameter on fatigue efficiency after 1-year and 3-year follow-up. Conclusion: The technical complication of dental implant include abutment screw loosening or fracture, abutment and superstructure fracture, and implant body fracture. The study has study has mainly focused on the impact of dental implant diameter on the efficiency of fatigue and reviewed a significant impact of dental implant diameter on the fatigue efficiency.

Case Control Analysis

Dental implant treatment is an important therapeutic modality with documented long-term success for replacement of missing teeth. However, dental implants can be susceptible to disease conditions or healing complications that may lead to implant loss. This case-control study identified several risk indicators associated with failure such as smoking and alcohol consumption. The use of postoperative antibiotics or wide-diameter implants may significantly reduce implant failure. Knowledge of patient-related risk factors may assist the clinician in proper case selection and treatment planning.

<p>Plant roots have been considered to be effective to reinforce shallow soil slopes under rainfall conditions. Recent evidence from geotechnical centrifuge modelling shows that plant roots could improve earthquake-induced slope stability and reduce slope crest settlement. However, the underlying fundamental mechanisms of soil-root mechanical interaction against seismic loading are unclear. Although there has been a large volume of studies focusing on root reinforcement, cyclic soil-root mechanical interaction has rarely been investigated. Moreover, whether plant roots could reduce the liquefaction potential of rooted soil. This presentation will present some new test data and evidence about (1) cyclic root biomechanical behaviour and (2) cyclic responses of root-reinforced soil. In part (1), results of cyclic uniaxial tensile tests on roots of a wide diameter range will be presented, including any root hardening or softening and change in the size of hysteresis loops under displacement-controlled loading condition. Special attention will be paid on any observation of cyclic-induced root mechanical fatigue. In part (2), results of a comprehensive set of monotonic and cyclic triaxial tests on rooted soil will be presented. The cyclic behaviour observed will be interpreted through the monotonic behaviour observed along both the triaxial compression and extension paths. Any change in soil failure mechanism from limited flow failure to cyclic mobility due to plant roots, and how/when this change occurs at different root volume and cyclic stress ratio, will be discussed in detailed. A new attempt to interpret the liquefaction resistance through an energy-based approach will be made to evaluate the energy dissipation mechanism in rooted soils.</p>
