Minor surgical procedures are increasingly being performed as outpatient procedures in settings outside hospital operating rooms (ORs). In electrophysiology, the recent miniaturization of insertable cardiac monitors (ICMs) has enabled the routine insertion of the device as a minimally invasive procedure without the need of a catheter OR. However, a shift to office-based environments for minor surgical procedures is associated with some concerns, particularly with respect to patient- and procedure-related safety in the new setting...

Most patients with chronic back pain suffer from degenerative thoracolumbovertebral disease. However, the following case illustrates that a localized peripheral nerve entrapment must be considered in the differential diagnosis of chronic back pain. We report the case of a 26-year-old woman with continuous excruciating pain in the lower back area. Previous treatment for nephroptosis was to no avail. On physical examination the pain was present in a 2 x 2 cm area overlying the twelfth rib some 4 cm lateral to the spinal process...

OBJECTIVE Fluorescence guidance with 5-aminolevulinic acid (5-ALA) helps improve resections of malignant gliomas. However, one limitation is the low intensity of blue light for background illumination. Fluorescein has recently been reintroduced into neurosurgery, and novel microscope systems are available for visualizing this fluorochrome, which highlights all perfused tissues but has limited selectivity for tumor detection. Here, the authors investigate a combination of both fluorochromes: 5-ALA for distinguishing tumor and fluorescein for providing tissue fluorescence of adjacent brain tissue...

Gastroschisis is a congenital abdominal wall defect and its management remains an issue. We performed a review of the literature to summarize its evaluation, management and outcome and we describe a new type of surgical reduction performed in our center without anesthesia (GA), immediately after birth, in the delivery room. Between January 2002 and March 2013, we enrolled all live born infants with gastroschisis referred to the third level Division of Obstetrics and Gynecology "San Camillo" of Rome.Two groups of infants were identified: group 1 in which gastroschis reduction was performed by the traditional technique and group 2 in which reduction was immediately performed after birth in the delivery room without GA...

PURPOSE OF REVIEW: The Shared Decision Making (SDM) model, a collaborative decision making process between the physician and patient to make an informed clinical decision that enhances the chance of treatment success as defined by each patient's preferences and values, has become a new and promising tool in the healthcare process; however, minimal data exists on its application in the orthopedic surgical specialty. Increasing evidence has demonstrated that this once novel idea can be implemented successfully in the orthopedic setting to improve patient outcomes...

The aim of this case report was to describe an innovative orthodontic treatment method that combined surgical and orthodontic techniques. The novel method was used to achieve a positive result in a case of moderate crowding by employing a computer-guided piezocision procedure followed by the use of clear aligners. A 23-year-old woman had a malocclusion with moderate crowding. Her periodontal indices, oral health-related quality of life (OHRQoL), and treatment time were evaluated. The treatment included interproximal corticotomy cuts extending through the entire thickness of the cortical layer, without a full-thickness flap reflection...

Three-dimensional (3-D) printing offers many potential advantages in designing and manufacturing plating systems for foot and ankle procedures that involve small, geometrically complex bony anatomy. Here, we describe the design and clinical use of a Ti-6Al-4V ELI bone plate (FastForward™ Bone Tether Plate, MedShape, Inc., Atlanta, GA) manufactured through 3-D printing processes. The plate protects the second metatarsal when tethering suture tape between the first and second metatarsals and is a part of a new procedure that corrects hallux valgus (bunion) deformities without relying on doing an osteotomy or fusion procedure...

The adult liver of most vertebrates is predominantly comprised of hepatocytes. However, these cells must work in concert with biliary, stellate, vascular, and immune cells to accomplish the vast array of hepatic functions required for physiological homeostasis. Our understanding of liver development was accelerated as zebrafish emerged as an ideal vertebrate system to study embryogenesis. Through work in zebrafish and other models, it is now clear that the cells in the liver develop in a coordinated fashion during embryogenesis through a complex yet incompletely understood set of molecular guidelines...

Epileptic spikes occur on the sub-second timescale and are known to involve not only epileptic foci but also large-scale distributed brain networks. There is likely to be a sequence of neural activity in multiple brain regions that occurs within the duration of a single spike, but standard electroencephalography-functional magnetic resonance imaging analyses, which use only the timing of the spikes to model the functional magnetic resonance imaging data, cannot determine the sequence of these activations. Our aim in this study is to temporally resolve these spatial activations to observe the spatiotemporal dynamics of the spike-related neural activity at a sub-second timescale...

BACKGROUND: Every day, millions of people undergo surgical procedures facilitated by anesthesia. Yet, there is no clinically accepted measure to predict the effects of sedation or anesthesia on the central nervous system. Auditory brain activation may provide an objective and quantifiable method to measure of the effects of sedation on neuronal processing. METHODS: This is a randomized clinical trial. Forty-eight healthy volunteers were randomly assigned to receive 1 of 3 sedative drugs (midazolam [n = 11], propofol [n = 12], or dexmedetomidine [n = 12]) at a concentration adjusted to achieve mild sedation by self-rating, or to a no-drug control group (n = 13)...

Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. The natural history of untreated significant TR portends an unfavourable outcome, but only a minority of patients is currently referred for surgical treatment. Organic TR (caused by primary abnormality of the leaflets) is relatively infrequent whereas secondary or functional TR (caused by dilatation of the tricuspid annulus, right ventricle [RV] and right atrium) is the predominant mechanism. The success of transcatheter therapies for left valvular heart disease over the last decade, has fuelled similar development of novel transcatheter devices for the treatment of TR...

Radiotherapy represents the most effective non-surgical modality in cancer treatment. MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression, and are involved in many biological processes and diseases. To identify miRNAs that influence the radiation response, we performed miRNA array analysis using MCF7 cells at 2, 8, and 24 h post irradiation. We demonstrated that miR-770-5p is a novel radiation-inducible miRNA. When miR-770-5p was overexpressed, relative cell number was reduced due to increased apoptosis in MCF7 and A549 cells...

Alterations in mitochondrial respiration contribute to the development and progression of cancer via abnormal biogenesis, including generation of reactive oxygen species. Ubiquinol-cytochrome c reductase hinge protein (UQCRH) consists of the cytochrome bc1 complex serving respiration in mitochondria. In the present study, we analyzed UQCRH abnormalities in hepatocellular carcinoma (HCC) and its association with clinical outcomes of patients. UQCRH expression in HCC was determined via semiquantitative and quantitative real-time reverse transcriptase polymerase chain reaction of 96 surgically resected HCC tissues positive for hepatitis B virus surface antigen...

Speckle tracking echocardiography (STE) has emerged as a novel angle-independent modality in assessing myocardial velocity, deformation, and strain. Its role in assessing change before and after aortic valve replacement in patients with aortic stenosis (AS) has recently generated interest. This review summarizes the practical utility and clinical implications of myocardial deformation by STE after surgical or transcatheter aortic valve replacement (TAVR). Overall, atrial strain and ventricular strain as measured by STE improve after surgical and transcatheter aortic intervention in short- and long-term follow-up with evidence of a more pronounced acute improvement in patients who undergo TAVR...

PURPOSE: An electromagnetic (EM) surgical tracking system was developed for orthopedic navigation. The reportedly poor accuracy of point-based EM navigation was improved by using anatomical impressions, which were EM-tracked personalized templates. Lines, rather than points, were consistently used for calibration and error evaluation. METHODS: Technical accuracy was tested using models derived from CT scans of ten cadaver shoulders. Tracked impressions were first designed, calibrated, and tested using lines as fiducial objects...

OBJECTIVE: Current techniques for mitral valve repair (MVR) in Barlow's disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes of the mitral valve in Barlow's disease has been developed. METHODS: Between 2009 and 2013, 22 patients underwent minimally invasive MVR for Barlow's disease and severe mitral regurgitation (MR). A simple, standardized technique was applied, including resection of P2 segment of posterior mitral leaflet (PML) with preservation of the shortest chordae, transfer of the preserved chordae to A2, and implantation of a semi-rigid open ring...
