Contribution in the diagnosis of ultrasonography perinephric pseudocyst uriniferous in a feline - case report

The renal pseudocysts are accumulations of fluid unilateral or bilateral perirenal location, contained in a capsule without epithelium, a characteristic that distinguishes them from true renal cysts. The capsule itself may have originated in the renal capsule or a localized inflammatory reaction. The nature of the fluid can vary, but the presence of ooze found the most common, but they are also called pseudocysts accumulations of urine, blood and lymph. The most frequently observed clinical sign is abdominal distention. However these nonspecific signs may be related to chronic kidney disease and azotemia that may develop before or after the formation of this lesion. The abdominal ultrasound is less invasive and allows you to diagnose this change more easily, also allowing the collection of fluid guided percutaneous and submit it to cytological, biochemical and bacteriological in order to obtain information about its nature. This paper aims to describe a case of perinephric pseudocyst in a cat uriniferous, highlighting the contribution ultrasound as a diagnostic method complementary quick and noninvasive, allowing evaluation of the architecture of the renal parenchyma, differentiation of cortex and spinal cord as well as detect changes in size and shape of it, aiming for better planning in clinical surgery.

Carta geotécnica das sub-bacias dos córregos do sossego e do barracão nos municípios de Americana e Santa Bárbara D'Oeste na escala 1:20.000

The Geotechnical Mapping is an extreme important tool for the urban planning, so the public authorities can establish guidelines for medium and long term for a better life conditions for the population. The division region between the cities of Americana and Santa Bárbara D’Oeste has an intense conurbation problem, which is causing problems of occupation in risks areas on environmental terms. In this context this project has as an objective the elaboration of a Geotechnical Map from the sub- basins of Sossego and Barracão rivers, whicht are located in between the area of the two cities, and presents some of the process causes of the conurbation problem. For this study, the following steps were proposed: bibliographic and topographic maps research for better knowledge from the theme and the area, and also preparing cartographic basis; making of preliminary geotechnical area map with a 1:10.000 scale, gather all the information acquired at the previous step and compartmentation of the area; field step to collect more information and soil for the laboratory analysis, objecting the characterization of the geotechnical unities; lab analysis; final geotechnical map preparation; and final report elaboration. The final product of this study is the Final Geotechnical Map, with a 1:10.000 scale, and the principal objective is to help the urban planning

Treatment of severe facial asymmetry secondary to osteochondroma of the mandibular condyle: case report

Osteochondroma (OC) is the most common benign tumor of long bones. However it is rarely found in the facial skeleton, being the coronoid process and mandibular condyle the most affected sites in this region. It basically consists in bone growth covered by cartilage. The etiology is still controversial: neoplastic, developmental, reparative and traumatic origins have been discussed in literature. The treatments of these lesions include total condylectomy or local resection of the lesion. This paper aims to report a case of a patient with history of trauma and possible fracture of the mandibular condyle in childhood, which in youth developed dentofacial deformity with severe facial asymmetry. The treatment consisted of resection of lesion both with maxillary and mandibular osteotomies associated with graft from the iliac crest bone. Actually, the patient is with a favorable aesthetic, without functional deficit and absence of lesion’s recurrence.

Acute fatty liver of pregnancy associated with severe acute pancreatitis: a case report

Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.

Influence of N-methyl-D-aspartate receptors on ouabain activation of nuclear factor-kappa B in the rat hippocampus

It has been shown that ouabain (OUA) can activate the Na,K-ATPase complex and mediate intracellular signaling in the central nervous system (CNS). Inflammatory stimulus increases glutamatergic transmission, especially at N-methyl-D-aspartate (NMDA) receptors, which are usually coupled to the activation of nitric oxide synthase (NOS). Nuclear factor-kappa B (NF-kappa B) activation modulates the expression of genes involved in development, plasticity, and inflammation. The present work investigated the effects of OUA on NF-kappa B binding activity in rat hippocampus and the influence of this OUA-Na,K-ATPase signaling cascade in NMDA-mediated NF-kappa B activation. The findings presented here are the first report indicating that intrahippocampal administration of OUA, in a concentration that did not alter Na,K-ATPase or NOS activity, induced an activation of NF-kappa B, leading to increases in brain-derived neurotrophic factor (Bdnf), inducible NOS (iNos), tumor necrosis factor-alpha (Tnf-alpha), and B-cell leukemia/lymphoma 2 (Bcl2) mRNA levels. This response was not linked to any significant signs of neurodegeneration as showed via Fluoro-Jade B and Nissl stain. Intrahippocampal administration of NMDA induced NF alpha B activation and increased NOS and alpha 2/3-Na,K-ATPase activities. NMDA treatment further increased OUA-induced NF-kappa B activation, which was partially blocked by MK-801, an antagonist of NMDA receptor. These results suggest that OUA-induced NF-kappa B activation is at least in part dependent on Na,K-ATPase modulatory action of NMDA receptor in hippocampus. The interaction of these signaling pathways could be associated with biological mechanisms that may underlie the basal homeostatic state linked to the inflammatory signaling cascade in the brain.

First report of sacbrood virus in honey bee (Apis mellifera) colonies in Brazil

Sacbrood disease, an affliction of honey bees (Apis mellifera) characterized by brood that fails to pupate and subsequently dies, is an important threat to honey bee health. The disease is caused by the sacbrood virus (SBV), a positive-, single-stranded RNA virus in the order Picornavirales. Because of the economic importance of honey bees for both pollination and honey production, it is vital to understand and monitor the spread of viruses such as SBV. This virus has been found in many places across the globe, including recently in some South American countries, and it is likely that it will continue to spread. We performed a preliminary study to search for SBV in two apiaries of Africanized honey bees in the State of Sao Paulo, Brazil, using RT-PCR and Sanger sequencing and found the first evidence of SBV in honey bee colonies in Brazil. The virus was detected in larvae, foraging and nurse bees from two colonies, one of which had symptoms of sacbrood disease, at the beginning of the winter season in June 2011. No SBV was found in samples from nine other nearby colonies.

Monitoring Drug Use Among HIV/AIDS Patients in Brazil: Should we Combine Self-Report and Urinalysis?

Illicit drug use in HIV-infected patients can be linked to impairment of physical and mental health, low health-related quality of life, and suboptimal adherence to HIV treatment. This study aimed to evaluate the correlation of self-report illicit drug use, urinalysis for cocaine and cannabis metabolites, and severity of dependence among HIV-infected patients on antiretroviral therapy (ART) in a treatment center in Brazil. Four hundred and thirty-eight outpatients of an HIV referral center were interviewed and assessed for drug use (lifetime, last year and last month). Urinalysis was performed to detect the presence of cocaine and cannabis metabolites in urine samples. Overall agreement between self-report and urinalysis was almost 68% for cannabis and higher than 85% for cocaine. Positive urinalysis was significantly associated with more than once a week cannabis (p < .0001) and cocaine (p <.0001) use during the last-month. Severity of Dependence Scale (SDS) properly predicted positive cocaine urinalysis results (area under the curve [AUC] = .81, p = .0001). Frequency of cannabis and cocaine use, SDS score degree and positive urinalysis for both drugs were correlated. Our findings suggest that positive self-report is a reliable predictor of positive urine sample both for cannabis and cocaine, but since the agreement was not perfect, there is a role for urine drug screening in the care of patients with HIV-related conditions.

The influence of breakfast and dairy products on dietary calcium and vitamin D intake in postpubertal adolescents and young adults

Background: Given the importance of both calcium and vitamin D for bone health and the high prevalence of vitamin D from around the world, the present study aimed to evaluate calcium and vitamin D intake in a group of healthy Brazilian adolescents and young adults and to examine the influence of breakfast and dairy products in the total intake of these nutrients. Methods: One hundred and sixty adolescents and young adults, aged 1620 years old, from a public school, participated in the present study. Three-day dietary records were used to assess calcium and vitamin D intakes. Serum 25(OH) D levels were measured using a radioimmunoassay kit. The results were expressed as the mean (SD). Results: Only 3.8% of the subjects met the daily adequate intake recommendation for calcium, and none for vitamin D [682.2 (132.2) mg day(-1) and 124.0 (28.0) IU day(-1), respectively]. 25(OH) D serum levels were insufficient in 51.5% and deficient in 9.7% of the individuals [72.5 (22.3) nmol L(-1)]. There was a significant positive correlation between dairy product intake with both calcium and vitamin D (r = 0.597 and r = 0.561, respectively; P = 0.000). Adolescents who ate breakfast had a significant higher mean calcium, vitamin D and dairy product intake than adolescents who did not report this meal. Conclusions: The majority of adolescents and young adults did not consume recommended intakes of calcium and vitamin D and also presented 25(OH) D insufficiency. The results indicate that a regular breakfast and the consumption of dairy products represent important strategies in improving calcium and vitamin D intake in the diet.

Measurements of D-0 and D* production in p plus p collisions at root s=200 GeV

We report measurements of charmed-hadron (D-0, D*) production cross sections at midrapidity in p + p collisions at a center-of-mass energy of 200 GeV by the STAR experiment. Charmed hadrons were reconstructed via the hadronic decays D-0 -> K- pi(+), D*(+) -> D-0 pi(+) -> K-pi(+)pi(+) and their charge conjugates, covering the p(T) range of 0.6-2.0 and 2.0-6.0 GeV/c for D-0 and D*(+), respectively. From this analysis, the charm-pair production cross section at midrapidity is d sigma/dy vertical bar(c (c) over bar)(y-0) = 170+/-45(stat)(-59)(+38()sys) mu b. The extracted charm-pair cross section is compared to perturbative QCD calculations. The transverse momentum differential cross section is found to be consistent with the upper bound of a fixed-order next-to-leading logarithm calculation.

Flares and variability from Sagittarius A(star): five nights of simultaneous multi-wavelength observations

Aims. We report on simultaneous observations and modeling of mid-infrared (MIR), near-infrared (NIR), and submillimeter (sub-mm) emission of the source Sgr A * associated with the supermassive black hole at the center of our Galaxy. Our goal was to monitor the activity of Sgr A* at different wavelengths in order to constrain the emitting processes and gain insight into the nature of the close environment of Sgr A*. Methods. We used the MIR instrument VISIR in the BURST imaging mode, the adaptive optics assisted NIR camera NACO, and the sub-mm antenna APEX to monitor Sgr A* over several nights in July 2007. Results. The observations reveal remarkable variability in the NIR and sub-mm during the five nights of observation. No source was detected in the MIR, but we derived the lowest upper limit for a flare at 8.59 mu m (22.4 mJy with A(8.59 mu m) = 1.6 +/- 0.5). This observational constraint makes us discard the observed NIR emission as coming from a thermal component emitting at sub-mm frequencies. Moreover, comparison of the sub-mm and NIR variability shows that the highest NIR fluxes (flares) are coincident with the lowest sub-mm levels of our five-night campaign involving three flares. We explain this behavior by a loss of electrons to the system and/or by a decrease in the magnetic field, as might conceivably occur in scenarios involving fast outflows and/or magnetic reconnection.

Bromocriptine Treatment for Inappropriate Lactation in Mares: A Case Report

Transient mammary gland development and lactation can occur eventually in weanling foals, yearlings, and adult mares without previous or recent history of pregnancy. The etiology of this condition has not been well documented, and there is limited information on the occurrence, frequency of episodes, composition, and treatment of galactorrhea secretion. This article reports a case of Brazilian Sport Horse mare, aged 10 years, with persistent lactation during 5 months. The treatment consisted of bromocriptine 0.04 mg/kg, b.i.d., orally, for 10 days, associated with hydrotherapy for 20 minutes, twice daily. After 20 days of the treatment onset, the mare was reevaluated, and a significant decrease in the volume of the udder and the amount of secretion produced was noted, and its aspect was clearer (serous) and consisted of more fluid compared with the one collected before treatment. No other clinical alterations or associated diseases were identified. Based on these findings, we suggest the diagnosis of idiopathic inappropriate lactation. Although there is no information about pharmacokinetics and description of the oral bromocriptine use in horses, being a therapeutic option for inappropriate lactation treatment in mares, it was effective at the recommended dosage.

Il principio di proporzionalità nella disciplina del mandato d'arresto europeo

Il presente lavoro affronta un tema di particolare attualità nella applicazione del mandato d’arresto europeo. Pensate per il contrasto alle forme più gravi di criminalità, le procedure di consegna hanno trovato sempre più spesso applicazione per vicende criminose di scarsa offensività, determinando conseguenze gravi sui diritti fondamentali degli individui coinvolti e mettendo a rischio la reciproca fiducia tra gli Stati membri nello spazio di libertà, sicurezza e giustizia. Ciò ha imposto alle istituzioni europee di richiamare gli Stati membri al rispetto del principio di proporzionalità, quale principio generale del diritto europeo. Il presente studio analizza i presupposti e le modalità di applicazione di tale principio, alla luce del nuovo assetto impresso all’Unione dal Trattato di Lisbona e nella prospettiva dei diritti fondamentali. In particolare, esso si sofferma sul ruolo da attribuire, rispetto allo specifico tema, alla Carta dei diritti fondamentali dell’Unione ed all’art. 52 par. 1 in essa previsto, ove emerge la valenza costituzionale del principio di proporzionalità.
