Esse trabalho teve como objetivo relatar o caso de obstrução uretral em um gato, Pelo Curto Brasileiro, castrado, de três anos de idade. A obstrução uretral é uma afecção urológica emergencial e recorrente na clínica de felinos que acomete os machos com frequência devido à disposição anatômica da uretra, longa e estreita. Podendo ser causada por tampões uretrais, urólitos, neoplasias ou transtornos funcionais da musculatura. O tipo de dieta, baixa ingestão hídrica, estresse, obesidade e manejo deficiente fazem com que esses animais tenham maior chance de desenvolver urólitos que levam a obstrução uretral. Os sinais clínicos mais observados são a lambedura excessiva do pênis, periúria, disúria e polaciúria. No presente relato, o animal apresentava retenções e obstruções urinárias recorrentes. No exame clínico, encontrava-se prostrado, desidratado, normocorado, com sensibilidade abdominal acentuada, vesícula urinária distendida e rígida à palpação. Foi realizada a estabilização do paciente e cistocentese de alívio. O paciente foi encaminhado para a internação onde realizou-se a desobstrução uretral com sondagem. No decorrer do dia, houve recidiva do quadro e foi submetido a cistotomia. Concluindo que o diagnóstico rápido e preciso é de suma importância para minimizar os efeitos deletérios causados pela obstrução uretral e em conjunto ao tratamento assertivo e individualizado garante qualidade de vida, bem-estar e saúde do animal.

Corpos estranhos são objetos ingeridos pelos animais que causam lesões na mucosa intestinal, e ao se tratar de corpo estranho linear pode agravar o quadro clínico acometer maior extensão e causar intussuscepção. Os sinais clínicos são amplos e inespecíficos, pode ocorrer apatia, anorexia, êmese, diarreia e sensibilidade abdominal. O diagnóstico deve incluir além da anamnese, exame físico, exames laboratoriais e exames de imagem. O objetivo do trabalho foi relatar o caso de corpo estranho linear em um cão, macho da raça Husky Siberiano, diagnosticado também com intussuscepção através do exame ultrassonográfico. A enterotomia foi realizada por se tratar de corpos estranhos que são considerados emergências cirúrgicas e os resultados e prognósticos observados no animal foram favoráveis, com uma recuperação no pós-operatório rápida.

Doenças com quadros obstrutivos, inflamatórios, parasitários e neoplásicos estão entre as patologias gastrointestinais que acometem cães e gatos, contudo, somente as manifestações clínicas, muitas vezes são insuficientes e subjetivas, e podem não contribuir para diferenciar lesões intestinais inflamatórias de neoplasias intestinais, sendo o exame ultrassonográfico a modalidade de diagnóstico mais eficiente e menos invasiva para detecção de tumores gastrointestinais em cães e gatos. Além disso, a ultrassonografia pode auxiliar a biópsia do segmento acometido, que pode ser realizada também por endoscopia ou ocasionalmente por laparotomia exploratória para obtenção do diagnóstico definitivo. O objetivo deste relato é salientar a importante contribuição do exame ultrassonográfico para o auxílio diagnóstico de neoplasias intestinais em cães e gatos, descrevendo um caso de neoformação duodenal (leiomioma) em um paciente da espécie canina.

Este trabalho teve como objetivo relatar o caso de um cão com corpo estranho esofágico, apontando os sinais radiográficos em decorrência deste, além de dissertar sobre os tipos, radiopacidade, localização frequente e conduta do médico veterinário radiologista diante desta situação. Casos de corpo estranho é relativamente comum em cães. Pode ter importância clínica ou não, é recomendado a realização de exames radiográficos simples ou contrastados que pode ser complementado com a ultrassonografia e outras modalidades como a tomografia computadorizada, ressonância magnética e endoscopia. O diagnóstico foi baseado na anamnese, sinais clínicos e imagens radiográficas do corpo estranho. Posteriormente, o paciente foi encaminhado ao centro cirúrgico para realização da esofagostomia e toracotomia para remoção dos fragmentos ósseos (corpo estranho). A utilização do exame radiográfico foi de extrema importância para determinar o diagnóstico de obstrução esofágica, possibilitando agilidade no encaminhamento e na sua intervenção.

Gastrointestinal foreign bodies (EC) are any objects ingested by animals, especially for companions, such objects cannot be digested or when they are digested, it occurs slowly. Small blunt foreign bodies can cause damage or not, and may cross the digestive system, in most cases these objects need to be removed, as they can cause a risk of obstruction or perforation depending on the material ingested by the animal. And for the removal of a foreign body in the gastric region, gastrostomy is a more suitable surgical technique as it results from an incision in the gastrointestinal wall. The diagnosis consists of the patient's clinical history linked to imaging exams such as radiography and ultrasound and complementary exams such as blood count and biochemistry. The objective of this work is to report the therapeutic-surgical conduct of a case of a foreign body in the gastric region, in a companion animal, treated at a private clinic located in the city of Imperatriz, MA. [ABSTRACT FROM AUTHOR]

Os corpos estranhos são objetos que podem ocasionar obstrução ou desconforto ao animal por geralmente serem grandes e apresentarem pontas finas e afiadas que podem perfurar órgãos, como a mucosa esofágica. Os cães são mais acometidos que os felinos devido aos hábitos alimentares indiscriminados. O esôfago apresenta uma anatomia tubular relativamente estreita, responsável por conduzir alimentos da faringe ao estômago. Os sinais clínicos de obstrução variam e dependem da duração, localização, grau de obstrução e acometimento da parede esofágica. O diagnóstico baseia-se no histórico clínico do paciente, radiografia ou endoscopia. A remoção cirúrgica é amplamente utilizada pela gama de possibilidades e a escolha do procedimento e protocolo varia de acordo com a localização, tamanho/ forma do corpo estranho, e grau da obstrução, como a toracotomia. O objetivo do presente trabalho é relatar um caso em que a esofagotomia torácica foi optada para a remoção de um corpo estranho que obstruía o lúmen esofágico na porção torácica de um cão.

Background: The term "rabbit gastrointestinal syndrome" (RGIS) refers to a decrease in peristaltic movements, which in some cases can progress to absolute inactivity of the digestive apparatus. This condition is mostly secondary to others that promote changes in gastrointestinal motility, such as dehydration, fiber deficiency, excess carbohydrates in diets, stress, and acute or chronic painful processes. Clinical manifestations are mostly nonspecific. Thus, a case of RGIS resulting from environmental change in a domestic rabbit (Oryctolagus cuniculus) is reported. Case: A 4-month-old male domestic rabbit weighing 0.962 kg was referred to a university veterinary hospital. The patient had a history of absence of defecation and anorexia for the past two days. The owner reported that the patient was apathetic but became aggressive when manipulated. The changes started after a move of residence. On physical evaluation, an increase in abdominal volume and a painful response to touch on the abdomen were observed. Complementary examinations were performed, such as a blood count and an ultrasound study. The blood tests showed no alterations, but the ultrasound evaluation showed the presence of free abdominal fluid, dilated intestinal loops due to fluid content, reduced gastrointestinal motility, and a hyperechoic structure associated with acoustic shading in the small intestine, all findings suggestive of obstruction. Given the failure of clinical management, the patient was referred for an exploratory laparotomy procedure followed by enterotomy. The obstruction point was located near the ileocecal junction. After surgery, analgesics, antibiotics, fluid therapy, anti-inflammatory drugs, intestinal motility inducers, and probiotics were prescribed. One week after the surgical procedure, the patient showed improvement in the clinical condition, with normal appetite, defecation, and docility. Discussion: RGIS is diagnosed based on the clinical history, clinical manifestations, and complementary examinations. In the reported case, the patient presented apathy, anorexia, absence of defecation, and aggressiveness on manipulation, which were associated with abdominal pain. In cases of RGIS, hematological changes may or may not be present, which matches the findings in this report. Imaging exams provide important information, such as the patient's condition and evolution. Ultrasound evaluation showed the presence of free abdominal fluid, dilated intestinal loops due to fluid content, reduced gastrointestinal motility, and a hyperechoic, immobile acoustic shading structure in the small intestine. Ultrasound findings were compatible with those found in cases of foreign-body obstructions, a common complication in RGIS. Initially, a clinical approach was taken, but in view of the unfavorable evolution of the case, with worsening motility and alterations in the imaging examination, a surgical approach was instituted. Intestinal obstructions in rabbits are usually found either in the proximal duodenum or near the ileocecal junction. In the presently reported patient, an obstruction was identified in the ileocecal junction region and the content found was composed of hair and dehydrated food. There are several conditions that can alter intestinal peristalsis in rabbits; in the present case, it was considered that the distress caused by moving to a new household led to a condition of RGIS. Despite the reserved prognosis associated with surgical interventions in the gastrointestinal system of rabbits, as described in the literature, in the present case this approach made it possible to preserve the patient's life, which returned to its normal activities and behavior.

A urolitíase é um processo patológico caracterizado pela presença de cálculos ou concreções no sistema urinário. De etiologia complexa e multifatorial, caracterizada pela formação de urólitos, que se alojam no trato urinário e preocupam a medida que determinam sua obstrução, passando a ser denominado de urolitíase obstrutiva. Os primeiros sinais clínicos manifestados pelos animais com urolitíase obstrutiva estão relacionados à dor. Objetivou-se com esse trabalho uma atualização sobre o quadro patológico de urolitíase obstrutiva em ovinos, abordando desde seu histórico, etiologia, epidemiologia, patogenia, sinais clínicos, diagnóstico, diagnóstico diferencial, tratamento, controle e prevenção.

A urolitíase canina e felina constitui-se em uma das principais causas de formação de cálculos urinários, que podem ocorrer desde a pelve renal até a uretra. Estes cálculos formados alteram a fisiologia do trato urinário, variando conforme a sua composição. Os urólitos mais encontrados em cães são os de oxalato de cálcio e fosfato amoníaco magnesiano. Já em gatos, os de oxalato de cálcio são os mais prevalentes entre os sete e nove anos de idade e os de estruvita em felinos jovens. Os sinais clínicos variam entre si, sendo o método de diagnóstico mais utilizado a radiografia simples ou contrastada. Como fatores predisponentes são citados a ocorrência de infecções do trato urinário, variações no pH urinário, fatores hereditários, tipo de dieta e pouca ingestão de água. Esta revisão tem como objetivo informar sobre os diferentes tipos de urólito em cães e gatos, como ocorre a formação dos mesmos e tratamentos empregados na forma clínica e cirúrgica.

Changes in the hydraulic performance of distinct models of drippers with treated domestic water are analyzed, coupled to empirical models for the variable operation time and effluent quality. An experiment, elaborated at the Universidade Federal Rural do Semi-Árido (UFERSA), comprised four irrigation units with three types of drippers (Plastro Hydrodrip Super, Netafim Tiran and Netafim PCJ-CNJ), with three replications (three lateral lines per dripper type). The coefficient rates of discharge variation and the reduction of relative discharge were determined every 80 h of operation with treated domestic residual water, coupled to physical, chemical and microbiological characteristics of the effluent till the completion of 400 h. Data underwent simple regression and multiple linear analyses. Dripper G1 had the greatest changes in hydraulic performance and was more liable to clogging than drippers Netafim Tiran and Netafim PCJ-CNJ. Nil and square root regression models best explained the relationship between variables CVQ and RQR and operation time of the irrigation units. Further, pH, SS, SD, Fe, Mg2+ and CT predominated in empirical models for hydraulic performance for the three dripper types. [ABSTRACT FROM AUTHOR]

RESUMO A colmatação é um fenômeno intrínseco aos sistemas alagados construídos (SACs) utilizados no tratamento de esgotos, sendo decorrente dos mecanismos de remoção de poluentes. Dentre os métodos disponíveis para a avaliação da colmatação, destaca-se o uso de traçadores para a obtenção das condições hidrodinâmicas dos SACs. No entanto, não há um traçador ideal; os salinos, por exemplo, são passíveis de absorção, mecanismo influenciado pelo estádio no qual a planta se apresenta. Assim, objetivou-se, com a realização do trabalho, avaliar a utilização do NaCl para caracterização do grau de colmatação e das condições hidrodinâmicas de SACs de escoamento horizontal subsuperficial, plantado e não plantado, verificar a confiabilidade do uso desse traçador em testes executados durante o estádio de crescimento (após o corte da parte aérea) e o florescimento da taboa (Typha latifolia), além da suscetibilidade de causar danos às plantas. Os resultados indicaram que o NaCl pode ser utilizado para estudos de comparação do grau de colmatação de SACs, inclusive não apresentando danos à taboa. Verificou-se que, após sete anos de operação, a unidade plantada encontra-se mais colmatada e com regime de escoamento mais turbulento. Também foi possível inferir que o corte das plantas propiciou aumento na dispersão no sistema.

The incidence of obstructive urolithiasis in felines has been diagnosed more frequently, causing a reduction in urinary flow, which can lead to serious kidney complications. Early identification and timely clearance are crucial to prevent severe kidney damage. The objective of this study was to evaluate a clinical case of a 4-year-old male feline of undefined breed with cystolithiasis, who underwent the percutaneous cystoscopy procedure. After two urethral probes due to recurrent obstruction, the feline underwent an ultrasound which revealed a bladder wall thickening and a large amount of sediment, associated with the proximal urethra's dilation, suggesting obstructive cystitis. During the third probe, urethral rupture was suspected due to resistance. A contrast x-ray confirmed urethral integrity and absence of malformations but detected a bladder stone. Percutaneous cystoscopy was chosen, resulting in the successful removal of a 3 mm stone and bladder lavage. The feline was probed for two more days, then discharged, with normal urinary flow, avoiding the need for urethrostomy. The animal, after 4 months post-surgery, did not present new obstructive conditions and is clinically stable, according to the owner. Percutaneous cystoscopy has proven to be effective and minimally invasive for removing uroliths, resulting in better outcomes and fewer clinical complications. This case highlights the importance of the procedure as an integral part of the treatment of similar cases in felines with cystolithiasis, contributing to the preservation of renal function and the patient's well-being. These results suggest the consideration of percutaneous cystoscopy as a valuable therapeutic approach in similar situations. [ABSTRACT FROM AUTHOR]

Este trabalho objetivou analisar o efeito das proporções do tempo de irrigação com água residuária de suinocultura (ARS) e água de abastecimento (AA) na alteração da vazão de gotejadores. O experimento foi montado no esquema de parcelas subsubdivididas, em delineamento inteiramente casualizado, com três repetições, tendo nas parcelas as proporções de tempo de irrigação (1E3A - 1 h de ARS e 3 h de AA; 2E2A - 2 h de ARS 2 h de AA; 3E1A - 3 h de ARS e 1 h de AA, e 4E - 4 h de ARS); nas subparcelas, os tipos de gotejadores (G1, G2 e G3) e nas sub-subparcelas os tempos das avaliações (0; 20; 40; 60; 80; 100; 120; 140 e 160 h). Os atributos físico-químicos e biológicos da ARS e AA foram obtidos a cada 20 h e 80 h, respectivamente. Realizou-se a medição de vazão nos 22 gotejadores identificados de todas as linhas laterais das unidades de irrigação, também a cada 20 h. Após 160 h, gotejadores e linhas laterais foram dissecados para investigação do material de obstrução. A combinação dos gotejadores G1 e G3 com as proporções de tempo de irrigação 1E3A e 4E minimizou o processo de entupimento, sendo as reduções nos valores de vazão de 16 e 8%, respectivamente, após 160 h de operação das unidades de irrigação.

A colelitíase, ou litíase biliar, é rara em felinos. O presente relato descreve o caso de um felino, macho, sem raça definida, com seis anos de idade que apresentava anorexia, dor abdominal, vômito e hipertermia. Ao exame ultrassonográfico de abdômen, a vesícula biliar apresentava formato irregular, paredes espessas e estruturas hiperecogênicas na região do seu colo e saída do ducto cístico, sugerindo presença de cálculos biliares. O paciente foi submetido à videolaparoscopia seguida de colecistectomia. Após sete dias, o animal obteve alta hospitalar e, aos 60 dias de pós-operatório, não demonstrou recidiva dos sinais clínicos.

Before 1898, the most sustained attempt by the United States to acquire Cuba occurred during the presidency of Franklin Pierce when the debate about slavery was roiling US domestic politics. Spain responded to the threat with a dramatic change of policy: in order to gain the favour and protection of Britain, it ordered that the slave trade to Cuba be ended. This article analyses Pierce's strategy and examines the complex jockeying it precipitated among Washington, London and Madrid. Mining US, British and Spanish archives, it is the first international history of the crisis that Washington's avarice provoked. [ABSTRACT FROM PUBLISHER]

The objective of this work was to evaluate the performance of a drip irrigation system applying water with high concentration of total iron, and to evaluate the efficiency of organic chlorine to prevent emitters clogging. The system consisted of four subunits receiving the following of dichlorine treatments: (N1 = 0, N2 = 15, N3 = 30 and N4 = 45 mg L-1 of free chlorine). The uniformity of application of water was evaluated using the coefficients of uniformity of Christiansen (CUC) and of Distribution (CUD), every 100 hours of use, for 700 hours, before and after the chlorination. Also the discharge coefficient variation (CVq) was evaluated. In the subunit with N1 there was a reduction in the values of CUC and CUD of 8,2 and 15,2%, respectively. The chlorination with dichlorine of sodium in the dosages of 15, 30 and 45 mg L-1 prevents the blockage of the dripper.O objetivo deste trabalho foi avaliar o desempenho de um sistema de irrigação por gotejamento, aplicando água com elevado teor de ferro total e, ainda, avaliar a eficiência da cloração orgânica na prevenção do entupimento. O sistema de irrigação foi constituído de quatro subunidades de irrigação, que receberam os seguintes tratamentos com dicloro: (N1 = 0, N2 = 15, N3 = 30 e N4 = 45 mg L-1 de cloro livre). A uniformidade de aplicação de água do sistema foi avaliada utilizando os coeficientes de uniformidade de Christiansen (CUC) e de Distribuição (CUD), a cada 100 horas de uso, durante 700 horas, antes e após a cloração. Também foi determinado o coeficiente de variação de vazão (CVq). Verificou-se uma redução nos valores do CUC e do CUD de 8,2 e 15,2%, respectivamente, na subunidade N1, refletindo no aumento do CVq. A cloração com dicloroisocianurato de sódio nas dosagens de 15, 30 e 45 mg L-1 previne o entupimento dos gotejadores.

Neste trabalho objetivou-se estudar o efeito da aplicação de esgoto doméstico tratado no desempenho de um sistema de irrigação por gotejamento. Para isso, o esgoto bruto foi submetido a uma sequência de tratamento e aplicado durante 120 horas na cultura de café, sendo avaliados a vazão do gotejador, os coeficientes de uniformidade e a distribuição. Foram também identificados os fatores causadores de obstrução. Concluiu-se que a formação de biofilme dentro dos gotejadores proporcionou redução da uniformidade de aplicação do efluente e que somente a filtração não previne a obstrução dos emissores.

JUSTIFICATIVA E OBJETIVOS: O edema pulmonar por pressão negativa tem sido definido como edema não-cardiogênico, com transudação de líquido para o interstício pulmonar, por aumento na pressão negativa intratorácica, ocasionado pela obstrução das vias aéreas superiores. Descreveu-se o caso de paciente hígida, submetida à anestesia geral, que apresentou edema agudo pulmonar após a extubação traqueal. RELATO DO CASO: Paciente de 23 anos, sexo feminino, estado físico ASA II, submetida à anestesia geral para videolaparoscopia ginecológica. O procedimento durou 3 horas, sem intercorrências. Após a extubação, a paciente apresentou laringoespasmo e diminuição da saturação de oxigênio. Houve melhora após colocação de cânula oral e administração de oxigênio, sob pressão positiva, com máscara facial. Estabilizado o quadro, foi encaminhada à sala de recuperação pós-anestésica, onde, logo após a admissão, apresentou edema agudo de pulmão com eliminação de secreção serossanguinolenta. O tratamento constou de elevação do dorso, oxigênio sob máscara, furosemida e restrição hídrica. A radiografia torácica mostrou imagem compatível com edema agudo pulmonar e área cardíaca normal. O eletrocardiograma (ECG), ecocardiografia e enzimas cardíacas estavam normais. A paciente apresentou boa evolução, recebendo alta hospitalar no dia seguinte, assintomática. CONCLUSÕES: O edema agudo de pulmão associado à obstrução das vias aéreas superiores é condição clínica que pode agravar procedimentos cirúrgicos de baixa morbidade e que aparece sobretudo em pacientes jovens. O tratamento deve ser instituído precocemente, pois a resolução também é rápida e, na maioria das vezes, sem seqüelas.JUSTIFICATIVA Y OBJETIVOS: El edema pulmonar por presión negativa ha sido definido como edema no cardiogénico, con transudación de líquido para el intersticio pulmonar, por aumento en la presión negativa intratorácica ocasionado por la obstrucción de las vías aéreas superiores. Se describió el caso de paciente saludable, sometida a la anestesia general, que presentó edema agudo pulmonar después de la extubación traqueal. RELATO DEL CASO: Paciente de 23 años, sexo femenino, estado físico ASA II, sometida a la anestesia general para videolaparoscopía ginecológica. El procedimiento duró 3 horas, sin intercurrencias. Después de la extubación, la paciente presentó laringoespasmo y disminución de la saturación de oxígeno. Hubo una mejoría después de la colocación de la cánula oral y administración de oxígeno bajo presión positiva, con máscara facial. Estabilizado el cuadro, se la llevó a la sala de recuperación postanestésica, en donde, en cuanto entró, presentó edema agudo de pulmón con eliminación de secreción sero-sanguinolenta. El tratamiento constó de elevación del dorso, oxígeno bajo máscara, furosemida y restricción hídrica. La radiografía torácica mostró una imagen compatible con edema agudo pulmonar y área cardíaca normal. El electrocardiograma (ECG), ecocardiografía y enzimas cardíacas estaban normales. La paciente presentó una buena evolución, recibiendo alta hospitalaria al día siguiente, sin síntomas. CONCLUSIONES: El edema agudo de pulmón asociado a la obstrucción de las vías aéreas superiores es una condición clínica que puede agravar los procedimientos quirúrgicos de baja morbidez y que aparece principalmente en pacientes jóvenes. El tratamiento debe ser empezado rápidamente, pues la resolución también es rápida y en la mayoría de las veces, no quedan secuelas.BAKGROUND AND OBJECTIVES: Negative pressure pulmonary edema has been defined as non-cardiogenic edema, with transudation of fluid to the interstitial space of the lungs due to an increase in negative intrathoracic pressure secondary to obstruction of the upper airways. This is the case of a healthy patient who underwent general anesthesia and developed acute pulmonary edema after extubation. CASE REPORT: A 23-year old female patient, physical status ASA II, underwent gynecologic videolaparoscopy under general anesthesia. The procedure lasted 3 hours without intercurrence. After extubation the patient developed laryngeal spasm and reduction in oxygen saturation. The patient improved after placement of an oral cannula and administration of oxygen under positive pressure with a face mask. Once the patient was stable she was transferred to the recovery room where, shortly after her arrival, she developed acute pulmonary edema with elimination of bloody serous secretion. Treatment consisted of elevation of the head, administration of oxygen via a face mask, furosemide and fluid restriction. Chest X-ray was compatible with acute pulmonary edema and normal cardiac area. Electrocardiogram (ECG), echocardiogram and cardiac enzymes were normal. The condition of the patient improved and she was discharged from the hospital the following day, asymptomatic. CONCLUSIONS: Acute pulmonary edema associated with obstruction of the upper airways can aggravate surgical procedures with low morbidity, affecting mainly young patients. Early treatment should be instituted because it has a fast evolution and, in most cases, resolves without lasting damages.

Smoking is considered the main cause of avoidable death worldwide, as it is also linked with cardiovascular and breathing impairments. Second hand smoke can induce breathing problems such as coughing, secretion, dyspnea and pneumofunctional parameters endangerment like the peak expiratory flow (PEF) that detects airways obstruction. This study analyzed Asces University (Faculdade Asces) both active and passive smokers airways obstruction degree; depicted the characteristics and tobacco usage history; yielded main respiratory symptoms and participants´ degree of nicotine dependence. This was a cross- -sectional descriptive analytical research where both passive and active smokers´ airways obstruction was quantified and compared. A total of 135 Law, Odontology and Pharmacy bachelor´s degree students from Asces University were participants. The assessment tool was composed of a questionnaire with a set of 10 clinical approaches questions, Fagerström Test for Nicotine Dependence (FTND) and Peak Flow Meter. For comparison between media a Student's t-test considered significant with p<0.05 was used. Coughing, mucus and dyspnea were respiratory symptoms identified in both groups. None of the participants showed high risk of nicotine dependence. Compared to active smokers a significant PEF decrease (p<0.001) averaging 381.3 ± 97.06 1/min was recorded in passive smokers group, denoting presence of airways obstruction in it. New studies regarding age, duration of smoke exposure and meddling in pneumofunctional parameters are highly recommended. [ABSTRACT FROM AUTHOR]

Este trabalho verificou o efeito da aplicação de esgoto sanitário tratado no desempenho de um sistema de irrigação por gotejamento montado em campo. Para a realização do experimento, utilizou-se um sistema de irrigação por gotejamento montado na Estação-Piloto de Tratamento de Esgoto do Departamento de Engenharia Agrícola daUniversidade Federal de Viçosa, Estado de Minas Gerais. Tal sistema constava de uma unidade de controle (composta por motobomba de 3 cv e filtro de 550 mesh), de linhas principal e de derivação e de linhas laterais com gotejadores do modelo G1. Os resultados mostraram que o efluente apresentou considerável potencial de obstrução de gotejadores, tendo como conseqüência direta o decréscimo tanto da uniformidade de aplicação do efluente quando da vazão dos gotejadores.This work verified the effect of the application of treated sanitary wastewater on performance of a drip irrigation system built in field. For the accomplishment of the experiment, a drip irrigation system was built in Sewer Treatment Pilot Plant of the Federal University of Viçosa’s, State of Minas Gerais, Agricultural Engineering Department. The system consisted of a control unit (composed of a 3 cv pump and a 550-mesh filtration system), lateral lines, and derivation and main lines with model dripper G1. Results showed that the effluent presented considerable potential of clogging drippers, having as direct consequence as much decrease of the uniformity application of effluent as flow rate of drippers.

Os resultados mostraram que o efluente apresentou considerável potencial de obstrução de gotejadores, tendo como conseqüência direta o decréscimo tanto da uniformidade de aplicação do efluente quando da vazão dos gotejadores

The aim of this study was to conduct a study on the occurrence and characterization of the main epidemiological, clinical and laboratory test findings, as well as the chemical composition of uroliths found in cases of urolithiasis in small ruminants treated at hospital routine. The study was conducted at the Clinic for Cattle, Garanhuns Campus of the Federal Rural University of Pernambuco, analyzing 98 cases of urolithiasis who were diagnosed in the period 2001-2011. The cases of urolithiasis represented 5.1% of clinical cases of small ruminants. All newborns were male and intact, with less than three years old at 90.56% and 66.60% of sheep from goats. The main clinical findings are: apathy and altered posture, showing signs of pain as arching, vocalization and gnashing of teeth, dehydration, difficulty urinating, besides presenting the swollen and sensitive to palpation preputial region. The blood count revealed leukocytosis with neutrophilia. In serum biochemistry was observed an increase in the levels of urea and creatinine, GGT, CK and glucose. With respect to mineral profile observed a hypocalcemia, hyperphosphatemia and hypermagnesemia. Featured deserved the result of the composition of uroliths, where there was a predominance of oxalate. The mortality rate of the animals was 56.4%. We conclude that the clinical and laboratory examinations are critical to assess the patient's condition and prognosis. [ABSTRACT FROM AUTHOR]

The knowledge about the formation and relations of the portal vein is important for surgeons and radiologists. The variations in the level of formation and the pattern of formation of portal vein might lead to confusions during radiological and surgical procedures. Here we present a rare variation in the formation of the portal vein as found during the cadaveric dissections. The portal vein was formed by the union of splenic vein, superior mesenteric vein and inferior mesenteric veins. The abnormal termination of left gastric vein into superior mesenteric vein before the formation of portal vein was also seen in the same cadaver. Identification of these variations is useful in managing traumatic rupture of the mesentery.O conhecimento sobre a formação e as relações da veia porta é importante para cirurgiões e radiologistas. As variações no nível de formação e o padrão de formação da veia porta podem causar confusões durante procedimentos cirúrgicos e radiológicos. Neste relato, apresentamos uma variação na formação da veia porta encontrada durante as dissecções cadavéricas. A veia porta foi formada pela união da veia esplênica, veia mesentérica superior e veias mesentéricas inferiores. A terminação anormal da veia gástrica esquerda na veia mesentérica superior antes da formação da veia porta também foi observada no mesmo cadáver. A identificação dessas variações é útil para tratar a ruptura traumática do mesentério.

Cholelithiasis, or gallstones, is rare in cats. This report describes the case of a six years-old mongrel cat male that had anorexia, abdominal pain, vomiting and hyperthermia. The abdominal ultrasound revealed a gallbladder with irregular shape and hyperechogenic structures, in the gallbladder's neck and in the output of the cystic duct, suggesting gallstones. The patient was undergone to a laparoscopic cholecystectomy. The animal was hospitalized for a week and after sixty days the owner no longer report clinical signs previously presented.

Introduction: Nasal irrigation solutions are widely used following endonasal surgery. These irrigation solutions remove infective debris and crusts, reducing the probability of synechia formation, and accelerate mucosal healing., Objective: The aim of the present study was to compare the effects of nasal irrigation solutions with different contents following septoplasty and concha radiofrequency., Methods: The present study was a prospective, randomized, controlled simple blind study of 120 patients who underwent septoplasty and bilateral concha radiofrequency. Patients were divided into four groups according to the nasal irrigation solution used: tap water, buffered isotonic saline, saline with xylitol, and hypertonic sea water. Patients were examined on the 7th and 15th postoperative days. A saccharine test was applied to determine mucociliary activity preoperatively and on the 7th and 15th postoperative days. Patients were asked about drying and obstruction using a 10cm visual analog scale. In addition, patients were examined to determine the crusting score., Results: There was no significant difference found in the preoperative and 7th and 15th postoperative days' mucociliary clearance times among the four groups. The crusting score was found to be significantly lower in the hypertonic sea water group (p<0.001). Drying and obstruction on the 7th and 15th postoperative days were found to be significantly more comfortable in the hypertonic sea water group (p<0.001)., Conclusion: Hypertonic sea water is the recommended irrigation solution, as it is associated with less crusting, drying, and obstruction in the nose for the postoperative period following septoplasty and concha radiofrequency., (Copyright © 2017 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.
