INTRODUCTION: Endoscopic anterior component separation (ECS) techniques facilitate tension-free midline closure of wide ventral hernia defects. We describe a novel approach with a precostal incision and a new cylindrical ballon trocar. MATERIALS AND METHODS: A single-center analysis of 19 patients undergoing ECS between January 1, 2014 and August 2, 2017 was performed with regard to improvement of technique. We currently start with a lateral precostal incision. This access in a low-fat and stable area allows for easy identification of the external oblique muscle with the ribs functioning as dorsal abutment for entering the correct plane between external and internal oblique muscles...

Cervical spine injuries are the most common spine injuries in the pediatric population. The authors present the youngest known patient who underwent cervical spine fusion to repair birth trauma-induced cervical fracture dislocation, resulting in spondyloptosis and spinal cord injury. A 2-week-old boy was found to have spondyloptosis and spinal cord injury after concerns arose from reduced movement of the extremities. The patient's birth was complicated by undiagnosed abdominal dystocia, which led to cervical distraction injury...

We have applied correlative microscopy to identify the key constituents of a dorsal rib fossil from Koreanosaurus boseongensis and its hosting mudstone discovered at the rich fossil site in Boseong, South Korea, to investigate the factors that likely contributed to diagenesis and the preservation of fossil bone. Calcite and illite were the commonly occurring phases in the rib bone, hosting mudstone, and the boundary region in-between. The boundary region may have contributed to bone preservation once it fully formed by acting as a protective shell...

BACKGROUND: Several authors mentioned surgical outcome for scoliosis associated with neurofibromatosis type 1 (NF-1). However, no studies have summarized long-term surgical outcomes after surgical treatment of early-onset scoliosis (EOS) with NF-1. The purpose of this study is to evaluate the long-term surgical outcome after early definitive spinal fusion for EOS in NF-1 patients. METHODS: We performed a retrospective review on a cohort of 11 patients diagnosed with EOS associated with NF-1 between 1990 and 2009 in our hospital...

BACKGROUND Flexibility evaluation methods were only used to assess the changes of coronal Cobb angle in patients with adolescent idiopathic scoliosis (AIS). Little attention was attached to the vertebral rotation in these methods. MATERIAL AND METHODS 21 patients with severe adolescent idiopathic scoliosis were enrolled in this study. Coronal flexibility and rotation correction were compared on the supine bending, traction and fulcrum bending radiographs. The apical vertebral body rib ratio (AVB-R), and Perdriolle rotation angles were used to measure the rotation of the main thoracic curve...

We present a study on electrical and optical trade-offs of the doping map in a ring modulator. Here, we investigate the effects of the high-doped region distance to edge of the waveguide sidewall. Four groups of ring modulators with different rib-to-contact distances are fabricated and measured where the key parameters such as extinction ratio, insertion loss, transmission penalty, and bandwidth are compared quantitatively. Small-signal responses for the selected ring modulators are simulated where results are in agreement with measurement results...

An analytic model is proposed to study the linearity performance of the silicon Mach-Zehnder optical modulator. According to the simulation results, we optimize the width of the silicon rib waveguide and the location of the PN junction to improve the linearity performance. The fabricated silicon Mach-Zehnder optical modulator has a spurious free dynamic range of 113.3 dB.Hz(2/3) and 88.9 dB.Hz(1/2) for the third-order intermodulation distortion and the second-order harmonic distortion. We also demonstrate the optical four-level pulse-amplitude-modulation (PAM-4) signal generation through the device...

We experimentally show an all-optical wavelength conversion of 8 × 32-GBd single-polarization 16QAM signals using a silicon nano-rib waveguide. The application of reverse biasing of the p-i-n junction of the waveguide allows a conversion efficiency of -8.5 dB with a measured 3-dB optical bandwidth of about 40 nm. Using digital coherent reception, it is shown that the receiver optical signal-to-noise ratio penalty, at a bit-error ratio of 1 × 10(-3), of the wavelength-converted signals over all eight channels was less than 0...

This article reports on an observational and treatment case series involving 22 adolescents and preadolescents treated over a 15 year period who had or appeared to be developing idiopathic scoliosis (IS). Common patterns of muscle and fascial asymmetry were observed and treated. Most of these individuals had spinal area pain and the trigger points (TrPs) apparently responsible for this pain were located in muscles at some distance from the spine, yet referred pain to locations throughout the thoracolumbar spine...

INTRODUCTION: Bilateral flail chest injuries are challenging in treatment and comparatively often require an operative stabilization of the anterior chest wall to re-establish normal physiological conditions of the chest wall in shape and statics. Various procedures have been described which are technically sophisticated for the surgeon. Consequently there is an increasing interest in potentials of operative care and their effectiveness on the anterolateral chest wall. MATERIALS AND METHODS: 12 Human cadavers were prepared and the natural Sternum Position (NP) was marked...

Mild-moderate blunt chest trauma is defined as a blunt chest trauma that is not caused by a high-energy mechanism, causing thoracic tenderness with or without rib fractures and that has no immediate life-threatening consequences for the patient. It is a frequent clinical situation in the emergency department. The most common radiological techniques that are used in this context are chest X-ray and thoracic computed tomography (CT). The CT scan is set as the gold standard. However, there are no current clinical-radiological guidelines that establish the adequacy of the requests of the CT scan...

Rib osteomyelitis is an infrequently occurring but important complication of breast implant surgery. Although prosthetic or surgical site infection (SSI) and rib osteomyelitis as separate entities are well described in the literature, only five cases of rib or sternal osteomyelitis related to implant placement have been reported globally. Historically patients who experience this complication have not demonstrated an identifiable prevalence of the traditional risk factors associated with SSI or rib osteomyelitis...

Well-vascularized composite tissue offers improved outcomes for complex head and neck reconstruction. Patients with vessel-depleted necks and failed reconstructions require alternative reconstructive options. We describe a pedicled internal mammary artery osteomyocutaneous chimeric flap (PIMOC) for salvage head and neck reconstruction. Bilateral dissections of 35 fresh cadavers were performed to study individual tissue components and vascular pedicles to develop the PIMOC technique. The flap was then utilized in a series of patients with vessel-depleted neck anatomy...

Biofilms help bacteria survive under adverse conditions, and the quorum sensing (QS) system plays an important role in regulating their activities. Quorum sensing inhibitors (QSIs) have great potential to inhibit pathogenic biofilm formation and are considered possible replacements for antibiotics; however, further investigation is required to understand the mechanisms of action of QSIs and to avoid inhibitory effects on beneficial bacteria. Lactobacillus paraplantarum L-ZS9, isolated from fermented sausage, is a bacteriocin-producing bacteria that shows potential to be a probiotic starter...
