The aim of the authors was to report a clinical case about immediate implant placement after the removal of complex odontoma. A 35-year-old female patient presented to private service complaining about absence of lower right first premolar. The computed tomographic showed radiopaque attenuation, surrounded by a narrow radiolucency in the area of dental absence, suggesting a mineralized lesion. The surgical removal of lesion was performed by intraoral access with general anesthesia and the implant of 3.75 × 10 mm (Neodent) was placed with the aid of a surgical guide, following the drill sequence established by the manufacturer...

INTRODUCTION: Immediate breast reconstruction (IBR) improves the quality of life of patients who undergo mastectomy. The latissimus dorsi flap (LDF) method provides particularly good aesthetic results, but its tolerance to subsequent radiotherapy remains unclear. We thus sought to assess tolerance and esthetic results and satisfaction, as reported by patients who underwent IBR by LDF with or without subsequent radiotherapy. MATERIALS AND METHODS: We performed a retrospective case-control study in a population of women who were diagnosed with breast cancer between January 1999 and January 2014 and who had mastectomies with IBR by LDF without prostheses...

BACKGROUND: Parkinson's disease (PD) is a progressive, neurodegenerative disorder with no disease-modifying therapies, and symptomatic treatments are often limited by debilitating side effects. In PD, locus coeruleus noradrenergic (LC-NE) neurons degenerate prior to substantia nigra dopaminergic (SN-DA) neurons. Vagus nerve stimulation (VNS) activates LC neurons, and decreases pro-inflammatory markers, allowing improvement of LC targets, making it a potential PD therapeutic. OBJECTIVE: To assess therapeutic potential of VNS in a PD model...

REVIEW
Christopher Nimsky, Barbara Carl
Intraoperative imaging has become widely accepted in neurosurgery in recent years. The possibility to objectively determine the extent of tumor removal is highly advantageous. If the resection is incomplete, clinicians can attempt to remove the residual tumor that was missed during the same operation. Furthermore, the positioning of implants in spinal surgery, as well as in cranial surgery, can be controlled and modified during the procedure. Intraoperative imaging acts as immediate quality control and offers improved patient safety...

Spoken language unfolds over time. Consequently, there are brief periods of ambiguity, when incomplete input can match many possible words. Typical listeners solve this problem by immediately activating multiple candidates which compete for recognition. In two experiments using the visual world paradigm, we examined real-time lexical competition in prelingually deaf cochlear implant (CI) users, and normal hearing (NH) adults listening to severely degraded speech. In Experiment 1, adolescent CI users and NH controls matched spoken words to arrays of pictures including pictures of the target word and phonological competitors...

INTRODUCTION: Priapism is defined as a full or partial erection lasting longer than 4 hours after sexual stimulation and orgasm or unrelated to sexual stimulation. The main goal of priapism management is to resolve the episode immediately to preserve erectile function and penile length. Corporal smooth muscle necrosis is likely to have already occurred, and medically refractory erectile dysfunction is expected in patients with a protracted episode. Penile prosthesis implantation (PPI) in the early or late phase of priapism can restore erectile function...

PURPOSE: To introduce a temperature sensor implant (TSI) that mimics an active implantable medical device (AIMD) for animal testing of MRI heating. Computer simulations and phantom experiments poorly represent potential temperature increases. Animal experiments could be a better model, but heating experiments conducted immediately after the surgery suffer from alterations of the thermoregulatory and tissue properties during acute testing conditions. Therefore, the aim of this study was to introduce a temperature sensor implant that mimics an AIMD and capable of measuring the electrode temperature after implantation of the device without any further intervention at any time after the surgery in an animal model...

PURPOSE: Few studies have investigated the risk factors for implant removal after treatment for spinal surgical site infection (SSI). Therefore, there is no firmly established consensus for the management of implants. We aimed to investigate the incidence and risk factors for implant removal after SSI managed with instrumentation, and to examine potential strategies for avoiding implant removal. METHODS: Following a survey of seven spine centers, we retrospectively reviewed the records of 55 patients who developed SSI and were treated with reoperation, out of 3967 patients who had spinal instrumentation between 2003 and 2012...

Various contraceptive methods are available to postpartum women including hormonal and nonhormonal barriers, as well as injectable forms. Of all the available birth control methods, intrauterine devices (IUD) are felt by many to be the near-ideal form of contraception, and are recommended by advocacy groups, physicians, and gynecological organizations worldwide. Immediate postpartum IUD insertion deserves greater attention because it can provide immediate contraception, prevents repeat unintended pregnancies, and may serve to reduce the incidence or need for secondary cesarean delivery; however, insertion of conventional T-shape IUDs immediately post placenta delivery is limited by their high expulsion and displacement rates...

Objective: Positron Lymphography using (18)F-FDG followed by Cerenkov guided resection of lymph nodes in healthy mice has previously been introduced by our group. Our aim in this study was to further assess the technique`s potential beyond merely localizing sentinel lymph nodes. We now aimed to evaluate the potential of Positron Lymphography to characterize the nodes with respect to their tumor status on order to identify metastatic lymph nodes. We explored if metastatic nodes could be distinguished from normal nodes via dynamic (18)F-FDG-lymphography, in order to then be resected under Cerenkov imaging guidance...

BACKGROUND: Breast reconstruction with implants is a real challenge in patients with large breast volume. Skin-reducing inverted-T mastectomy is the best solution for these patients. Delayed wound healing or necrosis at the T-junction area can be seen in this procedure, although it may also lead to severe conditions such as the exposure and loss of implant. In this article, the use of local pedicled flap for the management of these situations was discussed. METHODS: Between April 2010 and July 2015, 54 patients underwent breast reconstruction by inverted-T skin-reducing mastectomy and immediate implant-based breast reconstruction at our clinic...

INTRODUCTION: Effects of cardiac resynchronization therapy (CRT) on arrhythmogenicity and sudden death have not been fully ascertained. CRT has been shown to increase transmural dispersion of repolarization (TDR) immediately on implantation, that may favorably remodel on long-term follow-up. However, such a hypothesis has not been prospectively evaluated. METHODS AND RESULTS: We included 35 consecutive patients who underwent CRT implantation between September 2013 & August 2014 (mean age 56...

AIMS: The length of the tourniquet time during total knee arthroplasty (TKA) is related to the incidence of post-operative deep vein thrombosis (DVT). Our aim in this study was to investigate the effect of the early release of the tourniquet on the incidence of DVT in patients undergoing TKA. METHODS: A total of 200 patients who underwent TKA between November 2015 and November 2016 were prospectively enrolled. The tourniquet was inflated before surgery and released immediately after the introduction of the components (early release group)...

BACKGROUND: Catastrophic varus collapse is an uncommon mechanism of failure in primary total knee arthroplasty (TKA). Varus collapse has been associated with obesity and smaller implant sizes. However, to our knowledge, preoperative radiographic characterization of this cohort has not been performed. Therefore, the following study evaluated preoperative alignment and how this correlates with the degree of eventual varus collapse identified in this patient population prior to revision...

Frequent reports attest to the various advantages of tapered implant/abutment interfaces (IAIs) compared to other types of interfaces. For this reason, a conical IAI was designed as part of the development of a PEEK (polyetheretherketone)-based dental implant. This IAI is equipped with an apically displaced anti-rotation lock with minimal space requirements in the form of an internal spline. The objective of this study was the determination of the average insertion torque (IT) at failure of this design, so as to determine its suitability for immediate loading, which requires a minimum IT of 32Ncm...
