A totally implantable venous access device (TIVAD) abandoned for 5 years is re-accessed normally: A case report and literature review.

Regular flushing and locking of totally implantable venous access devices (TIVADs) is recommended to maintain their patency when not in use. In this case report, a 73-year-old male patient received radical resection for rectal carcinoma in January 2010. A TIVAD was implanted in 2014 and a total of 12 rounds of chemotherapy of FOLFIRI was completed in 2015.

Development of an anti-infective coating on the surface of intraosseous implants responsive to enzymes and bacteria.

Background: Bacterial proliferation on the endosseous implants surface presents a new threat to the using of the bone implants. Unfortunately, there is no effective constructed antibacterial coating which is bacterial anti-adhesion substrate-independent or have long-term biofilm inhibition functions.

Methods: Drug release effect was tested in Chymotrypsin (CMS) solution and S.

Prone position versus supine position in postoperative radiotherapy for breast cancer: A meta-analysis.

Background: This meta-analysis evaluates the difference of sparing organs at risk (OAR) in different position (Prone position and Supine position) with different breathing patterns (Free breathing, FB/Deep inspiration breath hold, DIBH) for breast cancer patients receiving postoperative radiotherapy and provides a useful reference for clinical practice.

Antibiotic-Loaded MMT/PLL-Based Coating on the Surface of Endosseous Implants to Suppress Bacterial Infections.

Background: Bone infections remain one of the most common and serious complications of orthopedic surgery, posing a tremendous economic burden to society and patients. This is because bacteria colonize and multiply on the surface of the implant. The (MMT/PLL) multilayer films have been shown to effectively release antibiotics depending on the changes in the microenvironment.

The effect of concurrent nasal surgery on the eustachian tube function and myringoplasty outcomes.

Objective: To investigate the Effect of concurrent nasal surgery on the eustachian tube function (ETF) and myringoplasty outcomes for the chronic perforations with coexistent nasal pathology.

Materials And Methods: We retrospectively reviewed the records of 93 patients with perforations who underwent same-day myringoplasty and nasal-septal surgery. Group A exhibited septal deviations (n = 34) and Group B inflammatory sinus disease (n = 59).

Effects of Chronic Exposure to Microcystin-LR on the Gut Microbiota of Male Mice.

Increasing evidence indicates that environmental pollutants can change human gut microbiota. Microcystin-leucine arginine (MC-LR), considered a major hazard to mammals, is one of the important contaminants. However, little is known about the long-term influence of MC-LR on gut microbial communities.

Full-thickness cartilage graft myringoplasty combined with topical application of bFGF for repair of perforations with extensive epithelialization.

Objective: The objective of this study is to evaluate the long term outcome of endoscope full-thickness cartilage graft myringoplasty combined with topical application of basic fibroblast growth factor (bFGF) for repair of perforations with extensive epithelialization.

Materials And Methods: In total, 65 perforations with extensive epithelialization of edges were divided into the endoscope full-thickness cartilage graft myringoplasty with (bFGF treatment group) and without topical application of bFGF (control group) groups. The outcomes were evaluated in terms of the hearing gain and graft success rate at 12 and 24 months post-surgery.

Clinical Findings of Cholesteatoma Behind an Intact Tympanic Membrane in Adults.

Objective: The aim of this study was to describe the clinical features and surgical results in a series of adult intact tympanic membrane cholesteatoma (ITMC).

Materials And Methods: The author retrospectively analyzed 17 adult patients diagnosed with ITMC who underwent surgery. The author investigated the demographic data, presenting symptoms, endoscopic findings, disease location, surgical technique, post-operative complications, and outcomes.

Endoscopic full-thickness cartilage-perichondrium double graft myringoplasty in adhesive perforation: retrospective case series.

Background: The adhesive perforation could be the sequela of adhesive otitis media, that partial tympanic membrane remnant is bound completely to the medial wall of the middle ear by fibrous adhesions. However, few studies have reported on the repairing of adhesive perforation.

Objectives: To evaluate the long-term outcome of endoscopic full-thickness cartilage-perichondrium double graft myringoplasty for adhesive perforation.

Endoscopic myringoplasty in pediatric patients: a comparison of cartilage graft push-through and underlay fascia graft techniques.

Background: Although myringoplasty is performed in pediatric patients, there is still no consensus on the graft material and surgerical procedure.

Objective: To compare the short-and long- term graft take rates of the cartilage push-through and fascia graft techniques employed during pediatric myringoplasty.

Materials And Methods: 93 pediatric patients with perforation who underwent myringoplasty were randomized into the cartilage push-through and underlay fascia graft group.

Comparison of biodegradable synthetic polyurethane foam versus Gelfoam packing in cartilage graft myringoplasty procedures.

Objective: To compare cartilage graft rates and graft morphologies when biodegradable Synthetic Polyurethane Foam (BSPF) and Gelfoam are used to pack the EAC after cartilage graft myringoplasty.

Therapeutic Effect of Resection, Prosthetic Replacement and Open Reduction and Internal Fixation for the Treatment of Mason Type III Radial Head Fracture.

Mason type III radial head fractures are a source of concern due to the severe injury and poor recovery. At present, radial head resection, open reduction and internal fixation (ORIF), and prosthetic replacement are three common treatment methods for these fractures. The clinical efficacy and postoperative complications are controversial, which makes it difficult for physicians to determine the most appropriate regimen.
