Canine Pyometra is a uterine disease that occurs in sexually mature bitches, with higher incidence in nulliparous and animals over 4 years and is characterized by presenting an accumulation of pus in the uterine lumen, usually occurring in diestrus. Laboratory tests are important tools for the detection of metabolic abnormalities associated with sepsis and renal function, which are serious consequences of pyometra. In blood the main findings are normochromic non-regenerative anemia, presence of dehydration, and sometimes thrombocytopenia. The WBC count may be normal but most often occurs a neutrophilic leukocytosis with a left shift, monocytosis and the presence of toxic neutrophils. In less than 1 / 3 of the animals the presence of azotemia is present and a density lower than 1035 is detected in the urine of almost 90% of bitches which may be in normal range at the onset of the desease. Urinary protein loss is rare but the protein may be elevated in the reagent strip due to urinary contamination by uterine secretion. The increase of gamma-glutamyltransferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) and creatine kinase (CK) may be present, indicating disorders in the liver. Currently, additional laboratory tests are being studied for the diagnosis of pyometra and its prognosis, such as the measurement of C-reactive protein and fibrinogen for monitoring the recovery of the inflammatory process and the urine electrophoresis to characterize the origin of proteinuria in these animals . The aim of this work is to review the literature on the main laboratory tests that aid the diagnosis of Pyometra

Study the semi-quantitative and quantitative technique in the diagnosis of catheter-related infections in newborns and to determine oxacillin resistance in Staphylococcus isolated. It was analyzed 353 catheter tips from 273 newborns in the Neonatal Unit of Hospital FMB. To confirm the diagnosis of infection, were analyzed the clinical data of newborns, the presence of at least one positive blood culture and growth of ≥ 1000 CFU/mL on quantitative culture and/or ³15 UFC on semiquantitative culture, with the same microorganism isolation (species and drug sensitivity) in blood culture and no other focus of infection except the catheter. The disk diffusion technique was used to check similarity of strains and resistance to oxacillin. Of the 353 tips analyzed, 39 were included in this study as the inclusion criteria. The semiquantitative culture was positive in 26 (66.7%) catheters and quantitative culture was positive in 24 (61.5%). Of 273 patients, 19 (6.9%) had a diagnosis of catheter-related bloodstream Infection (CR-BSI). Of the 19 episodes of CR-BSI, S. epidermidis was the predominant etiological agent (84.2%). The resistance to the antibiotic methicillin was found in 14 (73.7%) strains of Staphylococcus. The semiquantitative method was more sensitive (79%) compared with the quantitative method (63%). The use of antibiotics may have influenced the sensitivity of the quantitative method as the microorganisms present in the lumen are exposed to higher concentrations of antibiotics administered via the catheter

Function of the uterus is often compromised in cattle by bacterial contamination of the uterine lumen after parturition. Pathogenic bacteria often persist, causing uterine disease, a major cause of infertility in cattle. Knowledge of the immunological aspects of the uterus involved in maintaining reproductive healthiness is fundamental to the study of uterine infections that affect the uterus postpartum. Polymorphonuclear leukocytes have an important role because they are the first line of defense against colonization of bacteria in utero (Hammon and Goff, 2006). The establishment of uterine infection depends in parts of endocrine environment, particularly progesterone, which suppresses the immune system (Lewis, 2003). In the puerperium may occur uterine disorders, such as retained placenta, puerperal metritis, clinical and subclinical endometritis and pyometra, this review was proposed a study of the immunology involved in uterine health and a better understanding of uterine disorders, using the model of Sheldon et al. al, (2006) for classification of diseases, and a study of best treatment options and discussion about its functionality, because a lot of controversy among authors about choosing a treatment and another and between treated and untreated

The objective of the present text is to establish connections between literature and painting through the comparison between Oswald de Andrade’s poem “Longo da Linha” and Tarsila do Amaral’s painting “Palmeiras”, both belonging to the Brazilian Modernist movement Pau-Brasil. To emphasize also the step taken by the two artists, in Modernism, against the previous academicism, C. S. Peirce’s semiotics theory will be used as analytic basis to demonstrate, in Tarsila’s painting, a path towards planarity and stylization to produce quality effects, closer to the shape and the adventure of senses than to symbolization, whilst for Oswald, this same path leads to the presence of visualization as composition factor.

Annually hundreds of crab-eating foxes (Cerdocyon thous) are referred to rehabilitation centers and zoos in Brazil. The ultrasonographic study of wildlife species is an important tool for a non-invasive and accurate anatomical description and provides important information for wildlife veterinary care. The aim of the present study was to determine the characteristics of the main abdominal organs as well as the vascular indexes of the abdominal aorta and renal arteries of crab-eating foxes (Cerdocyon thous) using mode B ultrasonography and Doppler ultrasonography, respectively. Ultrasonographic features of the main abdominal organs were described and slight differences were noticed between ultrasound imaging of abdominal organs of crab-eating foxes and other species. The bladder presented wall thickness of 12 +/- 0.01 mm, with three defined layers. Both, the right and left kidneys presented corticomedullary ratio of 1: 1 and similarly to the adrenals and the liver, they were homogeneous and hypoechoic compared to the spleen. The spleen was homogeneous and hyperechoic compared to the kidneys. The stomach presented 3 to 5 peristaltic movements per minute, wall thickness of 39 +/- 0.05 mm and lumen and mucosa with hyperechoic and hypoechoic features, respectively. Small and large intestines presented 2 to 3 peristaltic movements per minute, wall thickness of 34 +/- 0.03 mm and three defined layers with hyperechogenic (submucosa and serosa) and hypoechogenic (muscular) features. Ovaries of the female crab-eating fox were hypoechoic compared to the spleen and with heterogeneous parenchyma due to the presence of 2x2 mm ovarian follicles. Prostates of the six males were regular and with a well defined boundary, with a homogeneous and hyperechoic parenchyma compared to the spleen. Vascular indexes of the abdominal aorta (PSV: 25.60 +/- 0.32 cm/s; EDV: 6.96 +/- 1.68cm/s; PI: 1.15 +/- 0.07 e RI: 0.73 +/- 0.07) and right (PSV: 23.08 +/- 3.34cm/s; EDV: 9.33 +/- 2.36cm/s; PI: 1.01 +/- 0.65 e RI: 0.65 +/- 0.16) and left renal arteries (PSV: 23.74 +/- 3.94cm/s; EDV: 9.07 +/- 3.02cm/s; PI: 1.04 +/- 0.31 e RI: 0.64 +/- 0.10) were determined. Thus, conventional and Doppler ultrasonographic imaging provides basic information that can be used as reference for the species as well for other wild canids and it is a precise and non-invasive method that can be safely used to evaluate and diagnose abdominal injuries in these patients.

Ayahuasca is a hallucinogenic brew traditionally used by Northwestern Amazonian indigenous groups for therapeutic purposes. It is prepared by the decoction of Banisteriopsis caapi with the leaves of Psychotria viridis. Banisteriopsis caapi contains β-carbolines that are inhibitors of monoamine oxidase and P. viris is rich in dimethyltryptamine, a 5-HT(1A/2A/2C) agonist. Acute ayahuasca administration produces moderate cardiovascular effects in healthy volunteers, but information regarding long-term use is lacking. This study investigated the effects of ayahuasca (2-4 mL/kg) in the rat aorta after acute and chronic (14 days) administration. Ayahuasca caused flattening and stretching of vascular smooth muscle cells and changes in the arrangement and distribution of collagen and elastic fibers. Chronic treatment with the higher dose significantly increased media thickness and the ratio of media thickness to lumen diameter. More research is needed on the cardiovascular function of long-term ayahuasca consumers.

The surface of the digestive tract of Hemisorubim platyrhynchos was analyzed by scanning electron microscopy. Morphometric studies by transmission electron microscopy were performed to analysis the intestinal microvilli. H. platyrhynchos is a Neotropical carnivorous freshwater catfish featuring a short digestive tract composed of a short esophagus, saccular stomach, and intestine with four regions: anterior, middle, posterior, and rectal. The esophageal surface is constituted by fingerprint-like microridges that anchor the mucosubstances secreted by goblet cells facilitating the passage of food. Goblet cells present the opening to the esophageal lumen, between the microridges. Club cells are in basal epithelium and they do not present the opening to the lumen. The gastric luminal surface shows polygon-shaped epithelial cells which secrete granules by exocytose to protect the gastric surface. The intestinal luminal surface reveals folds that are thicker in the anterior intestine than in the posterior intestine, increasing the absorptive surface area. The intestinal surface presents the microvilli of enterocytes and the opening of goblet cells. The morphometric analysis showed that the microvilli are longer in the anterior intestine, significantly decreasing towards the posterior intestine. The microvilli surface area significantly is greater in the anterior and middle intestine than in the posterior intestine. Numerous openings of goblet cells were observed in the posterior intestine acting in epithelial protection and lubrication. SCANNING 9999:1-8, 2015. © 2015 Wiley Periodicals, Inc.

The sialolithiasis is characterized by the formation of calcified structure called sialolith within the salivary ductal system. Although its etiology is unknown, it is believed that is from the deposition of calcium salts around an accumulation of organic leftovers in the lumen of the duct or be resulted by chronic sialadenitis and partial obstruction. In this study, the authors describe a case of a male patient, 46 years old, brown, who presented the complaint “pain under the tongue.” The presence of a hardened nodule located in the left sublingual fold was observed through intra-oral exam. Current considerations about treatment, clinical and radiographic characteristics were addressed in this work.

Each year individuals have sought a better quality of life and work, in this case, the science of Bio-insurance needs to keep up with technological advances and the needs of society to minimize or eliminate the risks of accidents. This study evaluated the most common accidents involving health staff from 2007 to 2011 in Araçatuba-SP. 478 accidents were recorded, and 78.7% with percutaneous involvement, 9% with intact skin, 4% with no skin intact, with 7.3 mucous and 1.05% other types of exposures. Most accidents were caused by needles with lumen (68.0%), followed by other agents (14.1%), accidents with blades (8.5%) or needles without lumen (5.5%); 3.7% did not answer and 0.2% were accidents with glasses. When checking the condition in which the accident occurred, 26.0% did not specify, 25.1% occurred in the disposal and / or handling sharp objects, 12.0% at the time of drug administration, 6.9% puncture, 3.7% occurred during recapping the needle. These data show that the most common accidents are those involving needles with lumen and / or sharp objects and due to these factors, the industry of health materials have sought alternatives to minimize such accidents as needles with protective, vacuum collection . Thus, it appears that reporting accidents is important for the development of technical and / or safer materials for patients and health workers.
