Contamination of recreational waters with cyanobacterial toxins continues to increase and presents a risk to animals and humans. Although cases of acute hepato- and neurotoxicoses in dogs following cyanotoxin exposure exist, no reports of skin-related reactions in dogs exist. A 5-year-old female spayed 34 kg Bracco Italiano was initially presented for rapid onset of severe pruritus and urticaria. Marked excoriation and erythema were noted over the chest and neck, while urticaria was noted in the inguinal regions and ventral abdomen...

Socio-sexual environments have profound effects on fitness. Local sex ratios can alter the threat of sexual competition, to which males respond via plasticity in reproductive behaviours and ejaculate composition. In Drosophila melanogaster, males detect the presence of conspecific mating rivals prior to mating using multiple, redundant sensory cues. Males that respond to rivals gain significant fitness benefits by altering mating duration and ejaculate composition. Here we investigated the underlying genome-wide changes involved...

INTRODUCTION: Negative pressure wound therapy (NPWT) is widely used in the treatment of open abdomen (OA). The use of dynamic fascial sutures (DFS) increases the rate of successful delayed closure by reducing fascial lateralization. We recently published a prospective controlled trial including 87 patients undergoing abdominal surgery for secondary peritonitis between 2007 and 2012. Patients were treated with NPWT and DFS for approximation of fascial edges. The present study represents a follow-up assessment of these patients 5-9 years after OA treatment with NPWT and DFS...

BACKGROUND: Acute appendicitis, especially if perforated at presentation, is often complicated by postoperative abscess formation. The detection of a postoperative abscess relies primarily on imaging. This has traditionally been done with contrast-enhanced computed tomography. Non-contrast magnetic resonance imaging (MRI) has the potential to accurately detect intra-abdominal abscesses, especially with the use of diffusion-weighted imaging (DWI). OBJECTIVE: To evaluate our single-center experience with a rapid non-contrast MRI protocol evaluating post-appendectomy abscesses in children with persistent postsurgical symptoms...

Odorant-binding proteins (OBPs) play a fundamental role in insect olfaction. In recent years, Galeruca daurica (Joannis) (Coleoptera: Chrysomelidae) has become one of the most important insect pests in the Inner Mongolian grasslands of China. This pest only feeds on the species of Allium plants, implying the central role of olfaction in its search for specific host plants. However, the olfaction-related proteins have not been investigated in this beetle. In this study, we identified 29 putative OBP genes, namely GdauOBP1-29, from the transcriptome database of G...

Deep sternal wound infection is a severe complication after open heart surgery. According to the different severity and dimensions of the deep sternal wound infection, the treatment method is different. In this study, we aimed to describe our experience with the rectus abdominis myocutaneous flap for large sternal wound management, especially when 1 or 2 internal mammary arteries were absent.Between October 2010 and January 2016, a retrospective review of 9 patients who suffered from the extensive thoracic defects after deep sternal wound infection was conducted...

Prior research in multiple insect species has demonstrated that insecticide-induced mortality varies according to the body region exposed on the insect. This variation has been demonstrated in Culex quinquefasciatus Say (Diptera: Culicidae), but has not been quantified using dose-response curves. Applications of technical permethrin or malathion to one of three body regions on Cx. quinquefasciatus resulted in dose-response curves that were not equivalent to one another. The generated LD90 values and curves for each body region were compared with previously reported LD values for analogous sites in several mosquito species, specifically the mesothorax...

PURPOSE: The diagnostic gold standard for nonalcoholic fatty liver disease is an invasive biopsy. Noninvasive Cartesian MRI fat quantification remains limited to a breath-hold (BH). In this work, a novel free-breathing 3D stack-of-radial (FB radial) liver fat quantification technique is developed and evaluated in a preliminary study. METHODS: Phantoms and healthy subjects (n = 11) were imaged at 3 Tesla. The proton-density fat fraction (PDFF) determined using FB radial (with and without scan acceleration) was compared to BH single-voxel MR spectroscopy (SVS) and BH 3D Cartesian MRI using linear regression (correlation coefficient ρ and concordance coefficient ρc ) and Bland-Altman analysis...

A 94-year-old Korean woman was seen in the Emergency Department after a fall. CT examination of the maxillofacial region found multiple small linear metallic densities in the subcutaneous soft tissues of the face. The appearance of these densities was unchanged when compared to a study performed 2 years prior; however, the imaging interpretations of these densities were markedly different. Additional imaging during the course of her hospital stay demonstrated numerous similar densities in the breasts, abdomen, hips, and legs-finally diagnosed as "charm needles...

INTRODUCTION: Intravenous leiomyomatosis (IVL) is a rare smooth muscle tumor, usually found in women with tumors of the reproductive organs, such as uterus myomatosous. Surgically, this case belies the call for sternotomy and two-stage surgery in caval IVL extending to the right atrium: we suggest one-stage median laparotomy as a minimal procedure with maximal benefit. PRESENTATION OF CASE: We present the case of a 60-year-old postmenopausal woman with suspected intravenous leiomyomatosis of the right internal iliac vein...

CASE: A 39 year-old man presented to the emergency department complaining of a cough of 2 months in duration. He also complained of weight loss of 20 pounds in two months and night sweats over the same period. An x-ray of the chest was performed and revealed innumerable lung nodules and masses. Computed tomography of the chest and abdomen were subsequently performed which confirmed the masses, but imaging did not reveal an obvious primary source. A testicular exam was performed but no obvious abnormalities were noted...

INTRODUCTION: Pheochromocytomas (PCCs);, or intra-adrenal paragangliomas (PGLs);, are neuroendocrine tumors arising within the adrenal medulla. Extra-adrenal paragangliomas may arise in the sympathetic or parasympathetic paraganglia and more rarely in other organs. One of the most common extra-adrenal sites is in the organ of Zuckerkandl, a collection of chromaffin cells near the origin of the inferior mesenteric artery or near the aortic bifurcation. The following is a case of a patient with resistant hypertension secondary to an extra-adrenal paraganglioma in the organ of Zuckerkandl...
