BACKGROUND CONTEXT: There is a broad spectrum of complications during or after surgical procedures, with differing incidences reported in the published literature. Heterogeneity can be explained by the lack of an established evidence-based classification system for documentation and classification of complications in a standardized manner. PURPOSE: To identify predictive risk factors for peri- and early post-operative morbidities in spine surgeries of different complexities in a large cohort of consecutive patients...

INTRODUCTION: A study in 2011 by (Doody et al. Ir Med J 106(10):300-302, 2013) looked at comparing inpatient adverse events recorded prospectively at the point of care, with adverse events recorded by the national Hospital In-Patient Enquiry (HIPE) System. METHODS: In the study, a single-centre University Hospital in Ireland treating acute hip fractures in an orthopaedic unit recorded 39 patients over a 2-month (August-September 2011) period, with 55 adverse events recorded prospectively in contrast to the HIPE record of 13 (23...

Elena Avram
Introduction: Congenital nasolacrimal duct obstruction is one of the most common causes of epiphora in newborns and the main cause of this condition is the persistence of Hasner membrane. Several treatment options are available, like conservative treatment, probing, irrigation, or more complex techniques. Objective: The objective of this paper is to discuss the efficiency of different treatment options addressing congenital nasolacrimal duct obstruction based on trials reported in literature. Methods: Clinical trials were identified on PubMed...

The response of a thin layer of granular material to an external pure shear imposed at its base is investigated. The experiments show that, even for noncohesive materials, the resulting deformation of the material is inhomogeneous. Indeed, a novel smooth pattern, consisting of a periodic modulation of the shear deformation of the free surface, is revealed by an image-correlation technique. These observations are in contrast with the previous observation of the fracture pattern in cohesive granular materials subjected to stretching...

This study focused on quantifying and characterising microbeads in biosolids (i.e., treated sewage sludge), and in examining interactions of microbeads with trace elements when biosolids are added to soil. Under laboratory conditions, batch experiments were conducted to investigate the adsorption of Cu onto pure and surface modified microbeads suspended in soil. The ecotoxicity of microbead-metal complexes to soil microbial activities was also investigated by monitoring basal respiration and dehydrogenase activity...

Fractures of the fifth metatarsal base are among the most common fractures of the foot. They are typically caused by indirect violence during sports activities. This region is also a site where stress fractures occur frequently. Diagnosis is based on the patients medical history, clinical examination and imaging methods. The fundamental imaging method is radiography of the foot in three views. MRI is used primarily for early diagnosis of stress fractures. CT examination is beneficial mainly in complex foot injuries, in order to rule out associated fractures...

BACKGROUND: The Focused Abdominal Sonography for Trauma (FAST) exam has been reported to be unreliable in pelvic fracture patients. Additionally, given the advent of new therapeutic interventions, such as Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), rapid identification of intraabdominal hemorrhage compared to zone III hemorrhage may guide different therapeutic strategies. We hypothesized that FAST is reliable for detecting clinically significant intraabdominal hemorrhage in the face of complex pelvic fractures...

Hengyan Zhang, Qiyi Li
RATIONALE: Surgical site infection (SSI) following spine surgeries involving internal fixation often require removing the instrument; however, this can cause spinal instability. Previous reports have demonstrated the usefulness of vacuum sealing drainage (VSD) therapy, but the cases require wound opening, aseptic condition to replace the VSD device, and a secondary operation to close the wound. Thus, to improve the VSD treatment and develop a maneuverable procedure, make sense in spine surgery...

INTRODUCTION: Yet uncommon, blindness is a potential associated injury of facial fractures. METHODS: Epidemiology, mechanisms, fracture types, and outcome of facial fractures-associated blindness in a 10-year period are retrospectively reviewed. RESULTS: Out of 907 facial fractures patients, 10 had blindness, giving a frequency of 1.1%. There were 9 men and 1 woman whom age range was 6 to 59 years (mean: 31.2 years). Intentional injury patients were significantly the most at risk of blindness (P = 0...

The aim of this study was to evaluate whether the amount of fracture displacement affects postoperative stability of isolated zygomaticomaxillary complex fractures and to determine whether the 1-point fixation method is as stable as 2- or 3-point fixation methods. The authors investigated 14 patients with 1-point fixation in the zygomaticomaxillary area (group A), 14 patients with 2-point fixation in the zygomaticomaxillary and frontozygomatic area (group B), and 13 patients with 3-point fixation in the zygomaticomaxillary, frontozygomatic, and infraorbital rim area (group C)...

There is still a gap between instrumental measurement and sensory evaluation because of the complexity of food texture in spite of many efforts. In sensory evaluation, the terms describing the texture should be well understood by panelists, which poses a problem of establishing lexicons and training panelists. In the instrumental measurement, more efforts are required to understand the large deformation and fracture behaviour of foods. The texture profile analysis (TPA) proposed by Alina Szczesniak, Malcolm Bourne and Sherman has been applied to many foods, and was useful to develop the understanding of textures...

Bone tissue engineering strategies that recapitulate the developmental process of endochondral ossification offer a promising route to bone repair. Clinical translation of such endochondral tissue engineering strategies will require overcoming a number of challenges, including the engineering of large and often anatomically complex cartilage grafts, as well as the persistence of core regions of avascular cartilage following their implantation into large bone defects. Here 3D printing technology is utilized to develop a versatile and scalable approach to guide vascularisation during endochondral bone repair...

Calcineurin is a calcium (Ca2+)/calmodulin-regulated protein phosphatase that mediates Ca2+-dependent signal transduction. Here, we report six heterozygous mutations in a gene encoding the alpha isoform of the calcineurin catalytic subunit (PPP3CA). Notably, mutations were observed in different functional domains: in addition to three catalytic domain mutations, two missense mutations were found in the auto-inhibitory (AI) domain. One additional frameshift insertion that caused premature termination was also identified...

Hydroxypropyl guar gum is considered to be a main component of oilfield fracturing wastewater (OFW). This work is intended to optimize the experimental conditions for the maximum oxidative degradation of hydroxypropyl guar gum by the coagulation and UV/H2O2/ferrioxalate complexes process. Optimal reaction conditions were proposed based on the chemical oxygen demand (COD) removal efficiency and UV_vis spectra analysis. The overall removal efficiency of COD reached 83.8% for a dilution ratio of raw wastewater of 1:2, pH of 4 and FeCl3 loading of 1,000 mg/L in the coagulation process; the dosage of H2O2 (30%,v/v) was 0...

INTRODUCTION: For several extremity fractures differences in morphology, incidence rate and functional outcome were found when polytrauma patients were compared to patients with an isolated injury. This is not proven for distal radius fractures (DRF). Therefore, this study aimed to analyse fracture morphology in relation to energy transfer in both poly- and mono-trauma patients with a DRF. METHODS: This was a retrospective cohort study. All patients aged 16 years and older with a DRF were included...

Management of complex foot injuries, which involve open fractures and severe trauma to soft tissues, represent a challenge to orthopedic clinicians. In the present case report, we treated a complex foot injury with a remodeled fibular osteocutaneous free flap to reconstruct the anterior and lateral areas of the foot. The flap survived completely. At the 9-month follow-up examination, bony union of the graft bone was identified by radiographic examination. The reconstructed foot could bear body weight, and the patient could maintain a bipedal gait without discomfort...

BACKGROUND: Transitions to sub-acute care are regularly complicated by inadequate discharge communication, which is exacerbated by a lack of clarity regarding accountability for important follow-up care. Patients discharged to sub-acute care often have complex medical conditions and are at heightened risk for poor post-hospital outcomes, yet many do not see a provider until 30 days post discharge due to current standards in Medicare regulations. Lack of designation of a responsible clinician or clinic for follow-up care may adversely impact patient outcomes, but the magnitude of this potential impact has not been previously studied...

Howard D Wang, Christopher Frost, Alessandro Cusano, Amir H Dorafshar
The surgical management of edentulous mandible fractures presents unique challenges secondary to poor bone stock and the absence of dentition to assist with fracture reduction. In complex injury patterns, such as bilateral edentulous mandible fractures, an external approach is often necessary to achieve adequate reduction and adaptation of a load-bearing reconstruction plate. We report a case in which computer-assisted design/computer-assisted manufacturing (CAD/CAM) was applied as an adjunct for the acute management of bilateral edentulous mandible fractures in a 58-year-old man...

For this study we developed an anatomical thin titanium mesh (ATTM) plate for Asian zygomaticomaxillary complex (ZMC) fracture repair with reduction guidance and fixation function. The ATTM plate profile was designed as an L-shape to fix at the anterior maxilla and lateral buttress of the ZMC. Computer-aided stamping analysis was performed on four screw-hole patterns in the ATTM plate - a control without screw-holes, square screw-holes, double screw-holes, and large-diameter, double screw-holes - using upper/lower dies of averaged ZMC reconstruction models...

BACKGROUND: Complex regional pain syndrome (CRPS) is frequently diagnosed in patients recovering from surgery or injury. The symptoms and signs included in consensus diagnostic criteria for CRPS are expected after injury. Categorizing symptoms and signs that occur on a continuum as disproportionate or not is subjective and prone to bias. Psychiatrists and psychologists do not diagnose CRPS and instead measure and treat anxiety and catastrophic thinking on its continuum. Given the expected variation in subjective diagnoses such as CRPS, this study addresses factors associated with use of this diagnosis and how it influences care...
