#1
E Carter Paulson, Earl Thompson, Najjia Mahmoud
BACKGROUND: Colorectal surgical procedures (CRS) are associated with the highest surgical site infection (SSI) rate among elective operations. A wide range of patient and surgical characteristics have been identified as risk factors for SSI. Most studies are limited by reliance on retrospective data or subset analysis of data that includes CRS. This study reflects analysis of SSI risk factors using prospectively collected data in an elective CRS population. PATIENTS AND METHODS: We analyzed data prospectively collected as part of a randomized, blinded trial of skin anti-sepsis in elective CRS to identify risk factors associated with SSI, including superficial or deep SSI or cellulitis within 30 days post-discharge...

A mycological survey on feet was performed in a nursing home with a geriatric hospital to ascertain the prevalence of tinea lesions. Of 100 subjects, comprising 62 in the nursing home and 38 in the geriatric wing, 70 were diagnosed with tinea pedis, tinea unguium (onychomycosis) or both of which 54 had onychomycosis alone, nine tinea pedis alone and seven had co-existing onychomycosis and tinea pedis. The most common clinical type of onychomycosis was distal lateral subungual onychomycosis (DLSO) at 30 cases, followed by superficial white onychomycosis (SWO) at 23 cases...

In external beam radiation therapy (EBRT), skin dose measurement is important to evaluate dose coverage of superficial target volumes. Treatment planning systems (TPSs) are often inaccurate in this region of the patient, so in vivo measurements are necessary for skin surface dose estimation. In this work, superficial dose distributions were measured using radiochromic translucent poly(vinyl alcohol) cryogels. The cryogels simultaneously served as bolus material, providing the necessary buildup to achieve the desired superficial dose...

We present a case of apparently uncomplicated lumbar decompression and discectomy with delayed postoperative neurological deterioration secondary to subdural hematoma at the thoracolumbar level of the spinal cord. Previously described subdural hematomas have occurred spontaneously or related to iatrogenic injury. Hitherto, no case of acute postoperative subdural hematoma has been reported in the postoperative setting in the absence of known iatrogenic dural injury. A 76-year-old male with central and lateral recess spinal stenosis underwent apparently uncomplicated bilateral L3-4 and left sided L4-5 decompressive partial laminectomies and discectomy...

BACKGROUND: Low flap complication rates and excellent aesthetic outcomes are now commonplace in breast reconstruction. As a result, attention is now being focussed on minimising donor site morbidity. Despite its potential donor site advantages, the superficial inferior epigastric artery (SIEA) flap is often discounted, given concerns about the high flap failure rates. In this study, we present our experience of using the SIEA flap in breast reconstruction and provide an algorithm based on pre-operative computed tomography angiography (CTA) to aid pre-operative planning...

Esophageal cancer has a poor overall prognosis and is frequently diagnosed at a late stage. Conventional treatment for metastatic esophageal cancer involves chemotherapy and radiation. Local disease control plays a significant role in improving survival. Endoscopic spray cryotherapy is a novel modality that involves freezing and thawing to produce local ablation of malignant tissue via ischemic mechanisms. Spray cryotherapy has been shown to be effective, particularly for early T-stage, superficial esophageal adenocarcinomas...

OBJECTIVE: Different gene expression profiles are observed in intracranial aneurysm tissue. Understanding these genes and what regulates their expression will help us understand intracranial aneurysm pathogenesis. We investigated whether differences in DNA methylation regulate gene expression in intracranial aneurysms. METHODS: Twenty intracranial aneurysm tissues were compared with 20 matched samples from the superficial temporal artery as controls. We detected the gene expression profiles in these samples using Human U133 Plus 2...

Honeybees are an important component of modern agricultural systems, and a fascinating and scientifically engrossing insect. Honeybees are not commonly used as model systems for understanding development in insects despite their importance in agriculture. Honeybee embryogenesis, while being superficially similar to Drosophila, is molecularly very different, especially in axis formation and sex determination. In later development, much of honeybee biology is modified by caste development, an as yet poorly understood, but excellent, system to study developmental plasticity...

PURPOSE: To investigate the blood supply to the nipple areola complex (NAC) on thoracic CT angiograms (CTA) to improve breast pedicle design in reduction mammoplasty. METHODS: In a single centre, CT scans of the thorax were retrospectively reviewed for suitability by a cardiothoracic radiologist. Suitable scans had one or both breasts visible in extended fields, with contrast enhancement of breast vasculature in a female patient. The arterial sources, intercostal space perforated, glandular/subcutaneous course, vessel entry point, and the presence of periareolar anastomoses were recorded for the NAC of each breast...

BACKGROUND: Superficial scald is a physiological disorder of apple fruit characterized by sunken, necrotic lesions appearing after prolonged cold storage, although initial injury occurs much earlier in the storage period. To determine the degree to which the transition to cell death is an active process and specific metabolism involved, untargeted metabolic and transcriptomic profiling was used to follow metabolism of peel tissue over 180 d of cold storage. RESULTS: The metabolome and transcriptome of peel destined to develop scald began to diverge from peel where scald was controlled using antioxidant (diphenylamine; DPA) or rendered insensitive to ethylene using 1-methylcyclopropene (1-MCP) beginning between 30 and 60 days of storage...

INTRODUCTION: External rotation and gravity stress radiographs have been described to distinguish stable supination-external rotation-II (SER-II) ankle fractures from unstable SER-IV fractures. It has been previously shown that both external rotation and gravity stress views are equivalent in their ability to diagnose deltoid ligament injury. It has also been shown that the position of the ankle influences the external rotation stress radiograph. However, no data of ankle position exist for gravity stress radiographs...

The separation performance of a chromatographic system is often described in terms of column efficiency and peak capacity. Thanks to the new developments in column technology over the past few years, the achievable peak capacity drastically improved and the analysis time can be significantly shortened. Indeed, highly efficient wide-pore reversed-phase (RPLC) materials packed with small fully porous and superficially porous particles can be successfully used for the analytical characterization of therapeutic proteins...

Candida albicans, along with some other non-albicans Candida species, is a group of yeast, which causes serious infections in humans that can be both systemic and superficial. Despite the fact that extensive efforts have been put into the discovery of novel antifungal agents, the frequency of these fungal infections has increased drastically worldwide. In our quest for the discovery of novel antifungal compounds, we had previously synthesized and screened quinoline containing 1,2,3-triazole (3a) as a potent Candida spp inhibitor...
