This report investigates the nursing procedure of a case of adjuvant therapy of rectal cancer on IV degree of acute radiation dermatitis patients in the penis and scrotum junction. The lesion degree gradually increased. Fixation of the dressing was difficult in the penis and scrotum junction. The concept of wet healing with new dressings was used in patient. The silver ion dressings were used in inhibiting infection, and the wound was covered by the rimmed foam dressings. When it comes to the shaping period, water gel transparent paste was applied instead to cover the wound...

Resistance of the melon line TGR-1551 to the aphid Aphis gossypii is based on preventing aphids from ingesting phloem sap. In electrical penetration graphs (EPGs), this resistance has been characterized with A. gossypii showing unusually long phloem salivation periods (waveform E1) mostly followed by pathway activities (waveform C) or if followed by phloem ingestion (waveform E2), ingestion was not sustained for more than 10 minutes. Stylectomy with aphids on susceptible and resistant plants was performed during EPG recording while the stylet tips were phloem inserted...

REVIEW
John E Kehoe, Matthew S Christman
PURPOSE OF REVIEW: Testicular remnants or nubbins are commonly found in the evaluation and treatment of cryptorchidism. While much debate focuses on the management of the nubbin itself, there is also great uncertainty and variation in the management of the contralateral descended testis. Herein, we review the relevant literature informing the decision to perform a contralateral orchiopexy. RECENT FINDINGS: Although there is very little recent literature directly addressing the question, some studies have better characterized differences in practice, the risk of intravaginal torsion in the contralateral testis and potential consequences in the selection of technique...

Bioprosthetic heart valves (BHVs), derived from glutaraldehyde crosslinked (GLUT) porcine aortic valve leaflets or bovine pericardium (BP), are used to replace defective heart valves. However, valve failure can occur within 12-15 years due to calcification and/or progressive structural degeneration. We present a novel fabrication method that utilizes carbodiimide, neomycin trisulfate, and pentagalloyl glucose crosslinking chemistry (TRI) to better stabilize the extracellular matrix of BP. We demonstrate that TRI-treated BP is more compliant than GLUT-treated BP...

INTRODUCTION AND HYPOTHESIS: The majority of patients with cystocele undergoing reconstructive surgery have combined defects of pubocervical fascia and uterosacral/cardinal ligament complex. In this regard, the simultaneous correction of both defects is rational. Furthermore, decreasing the use of synthetic materials in pelvic floor surgery is an important goal. The aim was to evaluate the objective and subjective cure rate of a hybrid technique: bilateral sacrospinous fixation using modern monofilament synthetic tape (apical sling) combined with the original technique of subfascial colporrhaphy...

INTRODUCTION: A potentially resectable bony metastasis in the context of oligometastatic colorectal cancer is uncommon. Bony metastases are usually considered a late event with poor prognosis and generally associated with liver and/or lung metastases. INDEX CASE: A previously healthy 33-year-old gentleman, with no family history of colorectal cancer, presented with rectal bleeding and at colonoscopy had a biopsy-proven adenocarcinoma of the rectum, 7 cm from the anal verge...

BACKGROUND: Optimal surgical management for flexion-distraction cervical spine injuries remains controversial with current guidelines recommending anterior, posterior, and circumferential approaches. Here, we determined the incidence of and examined risk factors for clinical and radiographic failure in patients with one segment cervical distraction injuries having undergone anterior surgical fixation. METHODS: A retrospective review of 57 consecutive patients undergoing anterior fixation for subaxial flexion-distraction cervical injuries between 2008-2012 at our institution was performed...

BACKGROUND: Avascular necrosis of the femoral head (AVNFH) typically constitutes 5 to 15% of all complications of low-energy femoral neck fractures, and due to an increasingly ageing population and a rising prevalence of femoral neck fractures, the number of patients who develop AVNFH is increasing. However, there is no consensus regarding the relationship between blood lipid abnormalities and postoperative AVNFH. The purpose of this retrospective study was to investigate the relationship between blood lipid abnormalities and AVNFH following the femoral neck fracture operation among an elderly population...

Johan P Mackenbach
AIMS: Social-epidemiological explanations of health inequalities usually take the existence of social inequality as a given and ignore the fundamental questions of why social inequality exists in the first place and why it is so persistent. I review here theories of the explanation of social inequality to identify the processes and/or structures responsible for its persistence. METHODS: This paper is a review of the relevant sociological literature. RESULTS: The sociological literature suggests that what persists over long periods of time is not a specific manifestation of social inequality but a 'meta-phenomenon': the fact that there are different social positions, that these social positions give access to different levels of resources in some graded way and that the distribution of individuals over social positions follows rules that create inequalities in the opportunities for achieving a more advantaged social position...

PURPOSE: We evaluate the clinical and functional outcome of open primary repair of acute TFCC tears in distal radius fracture, when there is gross intraoperative distal radioulnar joint (DRUJ) instability after fixation of the distal radius, in the absence of an ulnar styloid fracture or when the ulnar fracture fragment is too small to be fixed. METHODS: A retrospective review of our institution's distal radius fracture database over a 4-year period (January 2010 to December 2013)...

INTRODUCTION: The incidence of graft length mismatch (GLM) during anterior cruciate ligament (ACL) reconstruction is reported to be up to 13%, with a rate of 20% when using bone-patellar tendon-bone (BPTB) allografts. Multiple techniques have been described to accommodate for the longer BPTB graft. As no study has compared the biomechanical properties of these methods (with cyclic loading), we evaluated the strength of four different surgical techniques used to accommodate for GLM during ACL reconstruction...

PURPOSE: Sternoclavicular joint is an amphiarthrodial joint formed by the clavicle and sternal manubrium. This joint becomes chronically unstable in case of a medial clavicle dislocation or fracture, and improper treatment could cause malformation and pain. We aimed to determine the efficacy of a novel sternoclavicular hook plate for treatment of unstable sternoclavicular joint dislocation or fracture. METHODS: Between June 2011 and December 2013, the sternoclavicular hook plate was used to surgically treat 32 adult patients with unstable sternoclavicular joint dislocation or fracture...

Emerging cognitive control supports increasingly adaptive behaviors and predicts life success, while low cognitive control is a major risk factor during childhood. It is therefore essential to understand how it develops. The present study provides evidence for an age-related shift in the type of information that children prioritize in their environment, from objects that can be directly acted upon to cues signaling how to act. Specifically, gaze patterns recorded while 3- to 12-year-olds and adults engaged in a cognitive control task showed that whereas younger children fixated on targets that they needed to respond to before gazing at task cues signaling how to respond, older children and adults showed the opposite pattern (which yielded better performance)...

PURPOSE: We aimed to develop a new breast-immobilizing system for proton beam therapy (PBT) of early breast cancer (EBC) that would provide the optimum breast shape during the treatment as well as increased fixation reliability by reducing the influence of respiratory movement. METHODS: The breast-immobilizing system (HyBIS; Hybrid Breast-Immobilizing System) consists of a whole body immobilization system (WBIS), position converting device (to change patient position), photo scanning system, breast cup (made using a three-dimensional printer), breast cup fitting apparatus, breast cup holding device (to ensure the breast remains lifted in the supine position), and dedicated stretcher fixed to the WBIS (to carry the patient)...

Cyanobacteria have the potential to produce bulk and fine chemicals and members belonging to Nostoc sp. have received particular attention due to their relatively fast growth rate and the relative ease with which they can be harvested. Nostoc punctiforme is an aerobic, motile, Gram-negative, filamentous cyanobacterium that has been studied intensively to enhance our understanding of microbial carbon and nitrogen fixation. The genome of the type strain N. punctiforme ATCC 29133 was sequenced in 2001 and the scientific community has used these genome data extensively since then...

The less traumatic use of surgical adhesives rather than sutures for mesh fixation in hernia repair has started to gain popularity because they induce less host tissue damage and provoke less postoperative pain. This study examines the host tissue response to a new cyanoacrylate (CA) adhesive (n-octyl, OCA). Partial defects (3 × 5 cm) created in the rabbit anterior abdominal wall were repaired by mesh fixation using OCA, Glubran2(®)(n-butyl-CA), Ifabond(®)(n-hexyl-CA) or sutures. Samples were obtained at 14/90 days for morphology, collagens qRT-PCR/immunofluorescence and biomechanical studies...

BACKGROUND: Recurrent anterior shoulder instability after coracoid process transfers may be caused by trauma, sports injury, or technical failure of the index procedure. Surgical techniques vary with regard to graft orientation and positioning and number of screws utilized for fixation. PURPOSE: To identify surgical and patient-related factors associated with failure, defined as the need for revision surgery. We hypothesized that failures will occur more commonly with single-screw fixation and graft malposition...
