Background The presence of a cardiovascular implantable electronic device has long been a contraindication for the performance of magnetic resonance imaging (MRI). We established a prospective registry to determine the risks associated with MRI at a magnetic field strength of 1.5 tesla for patients who had a pacemaker or implantable cardioverter-defibrillator (ICD) that was "non-MRI-conditional" (i.e., not approved by the Food and Drug Administration for MRI scanning). Methods Patients in the registry were referred for clinically indicated nonthoracic MRI at a field strength of 1...

STATEMENT OF PROBLEM: Despite its clinical benefits, the immediate loading protocol might have a higher risk of implant failure than the regular protocol. Ultraviolet (UV) photofunctionalization is a novel surface enhancement technique for dental implants. However, the effect of photofunctionalization under loading conditions is unclear. PURPOSE: The purpose of this animal study was to evaluate the effect of photofunctionalization on the biomechanical quality and strength of osseointegration under loaded conditions in a rat model...

BACKGROUND/AIMS: Data on the timing of catheter removal technique following embryo transfer (ET) are quite limited. We aimed to compare the reproductive outcomes of intracytoplasmic sperm injection (ICSI)/ET cycles in which the transfer catheter was removed immediately with those in which the catheter was removed after a delay period and hereby to evaluate the impact that the time interval before removal of the catheter following embryo deposit may have on the fertility outcomes. METHODS: A prospective randomized study was designed...

To ensure that similar primary implant stability measured by resonance frequency analysis (RFA) could be obtained in different jawbone densities by using a specific surgical drilling protocol and, to correlate those RFA measurements with factors related to the implant design, width and length, we are performed a one-year prospective clinical study was carried out using 27 subjects. A total of 67 hydrophilic titanium implants were placed using a standard two-stage implant placement protocol. The bone type at each implant site was determined by evaluation of a preoperative, high-resolution cone beam computed tomography (CBCT) scan...

To assess the implant stability during different stages of healing in an immediate loaded implant soon after extraction. A 73-year-old female came with a chief complaint of bad smell and irritation in her lower front gum region. On examination, she was found to be completely edentulous in the maxillary arch and partially edentulous in the mandibular arch with only the canines present bilaterally. The posterior mandibular ridge was severely resorbed and hence could not be treated with a conventional mandibular complete denture...

BACKGROUND: Prior studies comparing unicompartmental knee arthroplasty (UKA) with total knee arthroplasty (TKA) in the elderly are limited by heterogeneity in arthritic disease patterns and patient selection. We report the results of UKA and TKA in patients 75 years and older with isolated medial compartmental arthritis, with special emphasis on immediate postoperative recovery, complications, reoperation rates, and implant survivorship at midterm follow-up. METHODS: A retrospective review was performed of all patients 75 years and older who underwent UKA or TKA at our institution between 2002 and 2012...

BACKGROUND: Acellular dermal matrices have been used for direct-to-implant (DTI) breast reconstruction (BR), eliminating the load of the lower pole skin envelope. However, the available allograft matrices add considerable health care costs. This study examined the long-term follow-up of synthetic ULTRAPRO(®) mesh as a low-cost potential alternative to biological matrices. PATIENTS AND METHODS: A retrospective cohort study was performed between January 2013 and January 2016, involved 112 early-stage breast cancer and/or BRCA 1/2 patients, and evaluated 189 immediate DTI BRs following skin-, areola- or nipple-sparing mastectomy using ULTRAPRO(®) mesh...

REVIEW
Amanda Cai, Howard J Eisen
PURPOSE OF REVIEW: As the heart failure population continues to age, the need for definitive therapies such as ventricular assist devices (VADs) to extend life and alleviate suffering from end-stage disease directly increases. The goal of this article is to examine the ethical principles of autonomy, beneficence, non-maleficence, and justice within the context of long-term VAD patients. RECENT FINDINGS: Survival rates in VAD-implanted patients have improved in parallel with modernization of device design and surgical technique, reaching that of cardiac transplantation at 1 year post-procedure...

BACKGROUND: To immediate reconstruct ptosis breasts, we used polyglactin (Vicryl; Ethicon Inc., Somerville, NJ, USA) mesh as an inferolateral sling. However, Vicryl mesh is absorbable and losing function as a supporting structure. We doubt about the stability of the blood supply to the inferior part of the flap when it is in direct contact with inner implant. In this study, we examine the complications and the safety of the skin flap of this absorbable mesh sling (AMS) procedure. METHODS: The outcomes of 80 cases were examined, and the 1-year safety record of 40 cases was assessed...

BACKGROUND: Irradiation of implant-based breast reconstructions (BR) is known to increase capsular contracture (CC) rates on average by 4-fold over non-irradiated reconstructions. The use of acellular dermal matrix (ADM) has been associated with lower CC rates in non-irradiated reconstructions (0-3%). Experimental and clinical studies suggest that ADM may also reduce CC rates in irradiated breasts. The aim of this study was to evaluate CC rates in non-irradiated and irradiated one- and two-stage BRs performed with the assistance of porcine ADM (PADM)...

BACKGROUND: The liver as transplantation site for human pancreatic islets is a harsh microenvironment for islets and it lacks the ability to retrieve the graft. A retrievable, extrahepatic transplantation site that mimics the pancreatic environment is desired. Ideally this transplantation site should be located subdermal for easy surgical-access but this never resulted in normoglycemia. Here we describe the design and efficacy of a novel prevascularized, subcutaneously implanted, retrievable poly (D,L-lactide-co-ε-caprolactone) (PDLLCL) scaffold...

OBJECTIVES: As a treatment for partial deafness with residual hearing in the lower frequency range, the combined acoustic and electric stimulation of the cochlea has become widespread. Acoustic stimulation is provided by a hearing aid's airborne sound and the electric stimulation by a cochlear implant electrode array, which may be inserted through the round window or a cochleostomy. To take advantage of that concept, it is essential to preserve residual hearing after surgery. Therefore, the intracochlear electrode array should not compromise the middle ear vibration transmission...

We report the case of a 82-year-old woman who was admitted to our institution with acute chest pain, nausea, and vomiting. Because of atrial fibrillation with intermittent bradycardia, a single-chamber pacemaker was implanted 4 years ago. The initial 12-lead ECG showed atrial fibrillation with a heart rate of 70 bpm, narrow QRS, and T‑wave inversions in the inferolateral leads. Coronary artery disease was excluded by immediate cardiac catheterization. A subsequent ECG three hours later showed a ventricular paced rhythm...
