This study assesses the efficacy of simulation-based episiotomy training (SBET) with beef tongue and sponge models in terms of the self confidence of midwifery students while performing episiotomy. Third-year midwifery students from Cumhuriyet University in the fall semesters of 2011 and 2012 were enrolled in the sponge and beef tongue model groups (n = 36 and n = 37, respectively). A checklist was prepared on the required skills for performing episiotomy which can be broken into three main parts, namely preparation, cutting and repairing and completion...

Osteoconductive, biocompatible, and resorbable organic/inorganic composites are most commonly used in fixation medical devices, such as suture anchors and interference screws, because of their unique physical and chemical properties. Generally, studies on biodegradable composites have focused on their mechanical properties based on the composition and the individual roles of organic and inorganic biomaterials. In this study, we prepared biodegradable organic/inorganic nanocomposite materials using the solvent mixing process and conventional molding...

Introduction: Foreign bodies and tissue reactions to foreign materials are commonly encountered in the oral cavity. Exogenous materials causing foreign body reactions may be metallic (amalgam) or nonmetallic (suture materials, vegetable matter). Implantation of food particles in the oral tissues has been known to cause reactive lesions such as oral pulse granuloma. Implantation could be through extraction sockets, deep periodontal pockets, associated with tumor growth, interdental areas of teeth, unfilled root canals, and grossly decayed teeth...

OBJECTIVE: Acquiring surgical skills requires regular practice. Medical evidence supports that these skills can be learned outside the operating room (OR). The aim of the current study was to describe the first laparoscopic simulator for ureteral reimplantation (LAP-SPUR) following Lich- Gregoir technique. MATERIALS AND METHODS: LAP-SPUR was manufactured using reusable and disposable materials. The technique can be summarized in the following five steps: (1) a transperitoneal approach; (2) extra-vesical ureteral dissection; (3) detrusor division until exposing the mucosa; (4) reimplanting ureter into the new tunnel; and (5) reapproximation and suturing of the detrusor...

In the field of neurosurgery, often the dura mater cannot be sutured, and consequently, it requires a duraplasty procedure using a dural fascial graft. Since 1890, various materials have been researched as dura mater substitutes. Amniotic membrane, for example, is suitable as a dural graft material and has been used in neurosurgery since 2012. However, there has been little research on human patient's dural healing after the use of amniotic membrane in their duraplasty procedure. To address this gap, a clinical experimental study was undertaken to evaluate the human dural healing of 16 patients who had undergone duraplasty in decompressive craniectomy surgery at Dr...

Prophylactic mesh augmentation (PMA) is the implantation of mesh during closure of an index laparotomy to decrease a patient's risk for developing incisional hernia (IH). The current body of evidence lacks refined guidelines for patient selection, mesh placement, and material choice. The purpose of this study is to summarize the literature and identify areas of research needed to foster responsible and appropriate use of PMA as an emerging technique. We conducted a comprehensive review of Scopus, Cochrane, PubMed, and <ext-link ext-link-type="uri" xlink:href="http://clinicaltrials...

Tendon-to-bone surgical repairs have unacceptably high failure rates, possibly due to their inability to recreate the load transfer mechanisms of the native enthesis. Instead of distributing load across a wide attachment footprint area, surgical repairs concentrate shear stress on a small number of suture anchor points. This motivates development of technologies that distribute shear stresses away from suture anchors and across the enthesis footprint. Here, we present predictions and proof-of-concept experiments showing that mechanically-optimized adhesive films can mimic the natural load transfer mechanisms of the healthy attachment and increase the load tolerance of a repair...

REVIEW
Martin Koller
Polyhydroxyalkanoates (PHA) are bio-based microbial biopolyesters; their stiffness, elasticity, crystallinity and degradability are tunable by the monomeric composition, selection of microbial production strain, substrates, process parameters during production, and post-synthetic processing; they display biological alternatives for diverse technomers of petrochemical origin. This, together with the fact that their monomeric and oligomeric in vivo degradation products do not exert any toxic or elsewhere negative effect to living cells or tissue of humans or animals, makes them highly stimulating for various applications in the medical field...

BACKGROUND: Patellar tendon repair with braided polyethylene suture alone is subject to knot slippage and failure. Several techniques to augment the primary repair have been described. Purpose/Hypothesis: The purpose was to evaluate a novel patellar tendon repair technique augmented with a knotless suture anchor internal brace with suture tape (SAIB). The hypothesis was that this technique would be biomechanically superior to a nonaugmented repair and equivalent to a standard augmentation with an 18-gauge steel wire...

REVIEW
Jhilmil Dhulekar, Agneta Simionescu
Hyperglycemia and dyslipidemia coexist in diabetes and result in inflammation, degeneration, and impaired tissue remodeling, processes which are not conducive to the desired integration of tissue engineered products into the surrounding tissues. There are several challenges for vascular tissue engineering such as non-thrombogenicity, adequate burst pressure and compliance, suturability, appropriate remodeling responses, and vasoactivity, but, under diabetic conditions, an additional challenge needs to be considered: the aggressive oxidative environment generated by the high glucose and lipid concentrations that lead to the formation of advanced glycation end products (AGEs) in the vascular wall...

BACKGROUND: Carpal tunnel syndrome is a common problem and surgical decompression of the carpal tunnel is the most effective treatment. After surgical decompression, the palmar skin may be closed using either absorbable or non-absorbable sutures. To date, there is conflicting evidence regarding the ideal suture material and this formed the rationale for our review. OBJECTIVES: To assess the effects of absorbable versus non-absorbable sutures for skin closure after elective carpal tunnel decompression surgery in adults on postoperative pain, hand function, scar satisfaction, wound inflammation and adverse events...

Background: Knee injuries encountered in clinical practice can involve avulsions of the biceps femoris from the fibula and proximal tibia. Advances in tendon repair methods now allow for repairs with increased surface areas using modern suture anchor techniques. Despite descriptions of repair techniques, there are no biomechanical studies on the biceps femoris for comparison. Purpose/Hypothesis: The objective of this controlled laboratory study was to determine the failure load of the native biceps femoris distal insertion and to evaluate modern repair techniques...

BACKGROUND: A simple suture technique in transosseous meniscal root repair can provide equivalent resistance to cyclic load and is less technically demanding to perform compared with more complex suture configurations, yet maximum yield loads are lower. Various suture materials have been investigated for repair, but it is currently not clear which material is optimal in terms of repair strength. Meniscal root anatomy is also complex; consisting of the ligamentous mid-substance (root ligament), the transition zone between the meniscal body and root ligament; the relationship between suture location and maximum failure load has not been investigated in a simulated surgical repair...

OBJECTIVES: The advantages of a bronchial sleeve resection are well established. A clear majority of reported cases are of upper lobe sleeve resection. Reimplantation of the upper lobe bronchus after a lower sleeve lobectomy or bilobectomy (the so-called Y-sleeve resection) is infrequent. Related technical peculiarities are the main issues. We present our experience and results in this setting. METHODS: Between 1989 and 2015, we performed 28 Y-sleeve resections of the left lower lobe (n = 18) or right middle and lower lobes (n = 10)...

Avoidance of hypotony in the early post-operative phase following glaucoma drainage device surgery is paramount, if serious complications are to be avoided. Current strategies of preventing early hypotony are either a valve mechanism, as those found in Ahmed Glaucoma Valve or flow restrictor as used in Baerveldt or Molteno implants. The Ahmed glaucoma valve has a pre-tensioned valve which opens and closes at the pre-determined level of intra-ocular pressure. Although the opening and closing pressure can be slightly inconsistent, coinciding with the change of material used in the plate construction, the reliability appears to have improved in recent years...

One of the main objectives of hallux valgus surgery is correction of the metatarsus primus varus deformity by osteotomy, arthrodesis, or soft tissue correction. The syndesmosis procedure uses intermetatarsal cerclage sutures to realign the first metatarsal and also induces a syndesmotic bonding between the first and second metatarsals to prevent metatarsus primus varus deformity recurrence. The purpose of the present study was to demonstrate radiologic evidence of the effectiveness of the syndesmosis concept and to identify the incidence and nature of deformity recurrence...
