RESUMO

A 4-month-old male Himalayan cat presented with clinical signs of acute lethargy and motor incoordination after being treated with amitraz for parasite control. On clinical examination, the patient was lethargic and ataxic with severe pulicosis, hypothermia, pale mucous membranes, bradycardia, weak femoral pulses, hyperglycemia, and bilateral mydriasis. Blood tests revealed non-regenerative hypochromic microcytic anemia. Serum alanine levels were elevated tenfold. The patient received supportive treatment with atipamezole (an α2-adrenergic antagonist) at a dose of 0.1 mg/kg intramuscularly. After 24 h of hospitalization and constant monitoring, the patient recovered and was discharged. The published literature showed that the active ingredient amitraz is effective in the treatment of some parasitic diseases in cats, such as scabies and demodicosis; therefore, it is still used for this purpose. Given the small therapeutic margin of this insecticide, veterinarians should caution owners about its potential toxicity. This report emphasized the significance of amitraz intoxication in feline species and the success of the treatment, which should be initiated in the first hour after intoxication.

Um gato da raça Himalaia, macho, com quatro meses de idade, apresentou sinais clínicos de letargia aguda e incoordenação motora após ser medicado com amitraz para controle de parasitas. No exame clínico, o paciente se apresentava letárgico e atáxico, com pulicose grave, hipotermia, mucosaspálidas, bradicardia, pulso femoral fraco, hiperglicemia e midríase bilateral. O exame de sangue revelou anemia microcítica hipocrômica não regenerativa. Os níveis séricos de ALT estavam 10x elevados. O paciente recebeu tratamento de suporte e administração de atipamezol (antagonista α2-adrenérgico) na dose de 0,1 mg/kg por via intramuscular. Após 24 horas de internação e acompanhamento constante, o paciente se recuperou e recebeu alta. Dados publicados na literatura demonstram que o princípio ativo amitraz é eficaz no tratamento de algumas doenças parasitárias em gatos como sarna e demodicose e, portanto, ainda é utilizado para esta finalidade. Dada a pequena margem terapêutica deste inseticida, os veterinários devem informar os proprietários sobre o seu potencial de toxicidade. O objetivo deste relato é enfatizar a importância da intoxicação por amitraz na espécie felina e o sucesso do tratamento, que deve ocorrer nas primeiras horas após a intoxicação.

Introduction:Endometriosis is a gynecological pathology that is quite prevalent among women of multiple age groups, representing a constant challenge to fertility, sexuality, and other aspects of quality of life.Objective:To evaluate the epidemiological profile, forms of treatment and biopsychosocial aspects associated with the sexual health of women with endometriosis.Methodology:This is an integrative review of the literature whose guiding question was "How does endometriosis influence the biopsychosocial aspects inherent to female sexual behavior?". The search strategy "Endometriosis AND Dyspareunia AND Quality of Life" was applied in the Biblioteca Virtual em Saúde (BVS) and in the PubMed database, with the "last 10 years" filter applied on both platforms. Inclusion criteria: studies that addressed cisgender women, of childbearing age, with active sexual life, previous diagnosis of pelvic or deep endometriosis and sexual disorders or complaints. Exclusion criteria: articles that included women using psychotropic drugs. Results:Initially, 227 articles were obtained. After primary analysis, 189 studies were excluded, only 38 going on to the next stage. Of these, only 15 met the criteria and were considered valid to be part of the present study. In the sexual sphere, endometriosis can lead to a reduction in the frequency of intercourse, bleeding during or after coitus, lack of interest in foreplay, discomfort in certain positions, relationship endings, marital conflicts, and, above all, dyspareunia.Conclusions:Given the damage to various areas of life and female well-being caused by endometriosis, it is essential to improve the quality of health services for early diagnosis and effective interventions, as well as support, reception, and continuous multidisciplinary monitoring. Furthermore, adaptation, understanding and concern from partners are fundamental for women to be able to better manage such challenges (AU).

RESUMO

OBJECTIVES: The aim of this study was to evaluate the influence of a preappointment oral dose of gabapentin on the neurological examination of cats. METHODS: A prospective, randomized and blinded clinical trial was conducted in 35 client-owned healthy cats. Cats were scheduled for two appointments and randomly assigned to receive either a placebo or a 100 mg gabapentin capsule prior to the second veterinary visit. A neurological examination was performed during each visit, and the results were compared between groups. Normal/abnormal response rates for each test were based on the number of cats that allowed the test to be performed. RESULTS: Gabapentin was administered to 17 cats. Gait and postural reactions were significantly affected in the gabapentin group. Comparing the gabapentin with the placebo groups, proprioceptive ataxia was identified in 4/17 (23.5%) vs 0/18 cats (P = 0.0288); paw placement deficits were seen in 10/11 (90.9%) vs 1/4 (25%) cats; table tactile placement deficits were identified in 13/17 (76.5%) vs 0/18 cats (P <0.0001); hopping deficits were seen in 5/17 (29.4%) vs 0/16 cats (P = 0.0185); and abnormalities on wheelbarrowing and extensor postural thrust were reported in 5/17 (29.4%) vs 0/18 cats (P = 0.0129). These results had no correlation with age or dose/kg received. No significant difference was noted in the assessment of level and content of consciousness, posture, cranial nerves and spinal nerves. No significant differences were noted in test compliance or examination duration. CONCLUSIONS AND RELEVANCE: Gabapentin significantly altered gait analyses and postural reactions in this group of healthy cats. The administration of gabapentin could lead to false-positive results and, possibly, an incorrect identification of neurological lesions. In contrast, gabapentin did not impair the assessment of cranial nerves and spinal reflexes, which can be assessed in patients receiving the drug.

RESUMO

OBJECTIVES: The aim of this study was to evaluate, using echocardiography, the effects of oral administration of a single dose of gabapentin on the physiologic variables (heart rate [HR], respiratory rate [RR] and systolic blood pressure [SBP]) and systolic and diastolic cardiac function of healthy cats. METHODS: This was a prospective, randomized and blinded study with 40 healthy cats aged between 6 months and 2 years. The cats' health status was assessed on the first appointment (T1) when they underwent a physical examination, complete blood count, biochemical profile, assessment of physiologic variables and echocardiogram. The echocardiogram was used to measure the left ventricle's (LV) internal diameter during systole and diastole, isovolumic relaxation time, transmitral flow, E-wave deceleration time and HR. The cats were randomly divided into two groups: (1) a treatment group with 20 cats that received a single oral dose of gabapentin (100 mg/cat); and (2) a control group with 20 cats that received a single oral dose of placebo. All variables of the physiologic and echocardiographic variables were re-evaluated 1-3 weeks after T1 (T2), 90 mins after medication or placebo administration. RESULTS: There was no difference in the physiologic variables evaluated in both groups. The proportion of cats in the treatment group that had their ventricular filling waves fused on T1 but did not have them fused on T2 was significantly higher (45%) compared with cats in the control group (15%; P = 0.0384). CONCLUSIONS AND RELEVANCE: There was no difference between the groups in regard to SBP, HR, RR and echocardiographic variables. Gabapentin improved evaluation of diastolic function on echocardiogram because it reduced the fusion of ventricular filling waves during the evaluation of the diastolic function of the LV. Gabapentin did not cause adverse effects on the cardiovascular hemodynamics of young healthy cats.

RESUMO

We describe a minimally invasive alternative approach in a patient with infected hepatic cyst to stabilize the patient before definitive surgery. A 58-year-old man presented with fever and hypotension after 2 weeks of asthenia, chills, weight loss, slight abdominal pain, and a previous asymptomatic simple hepatic cyst. On ultrasound, a giant heterogeneous hepatic cyst with thick wall was noted. A positron emission tomography-computed tomography scan was indicated and demonstrated high uptake (standardized uptake value = 7.6) in the wall of the cyst, suggestive of infection. He underwent percutaneous drainage guided by the tomography. A 12 Fr drain was positioned inside the collection and 5 L of purulent material was aspirated from the cyst, and at day 12th, surgical resection was performed. Histopatological analysis confirmed a simple biliary cyst. The patient remains asymptomatic on 1-year follow-up. Percutaneous drainage before surgical treatment allowed the definitive approach to be performed with the patient in better clinical conditions.

RESUMO

OBJECTIVES: To describe the experience of our institution in image-guided renal nodules percutaneous cryoablation, evaluating demographic and technical aspects as well as efficacy, safety and follow up. MATERIALS AND METHODS: Retrospective study approved by our institutional review board. Seventy-one renal tumors evaluated in 60 patients treated with image guided percutaneous renal cryoablation from January 2009 to December 2015. No patient was excluded from study, even those who were lost on follow up. All the procedures were guided both by ultrasound and tomography. An argon and helium based cryoablation machine was used for all treatments. Hydrodissection was performed when the bowel or ureters were within 1 cm (iodinated contrast media in dextrose solution). Complications were assessed by the terminology criteria of the National Institutes of Health (NIH). Patients were monitored and evaluated by ultrasound, tomography, MRI and/or PET-CT. RESULTS: In most procedures (91.9%) only one nodule was treated. Nodules had a median size of 1.6 cm. Most nodules (61,9%) were exophytic. Hydrodissection and retrograde warm pyeloperfusion were performed in most procedures. Among all variables evaluated in univariate analysis, nearness of nodule to collecting system and anterior/posterior location were significantly associated with PRCA complications. No other factor evaluated was significantly associated with complications. CONCLUSION: PRCA is solid alternative to traditional surgical therapies for treatment of small renal tumors in wide subset of patients. Medium term evidence shows excellent long-term oncological results, similar to nephrectomy, with minimal risk of major complications.

RESUMO

OBJECTIVES: Verify the in-vitro effect of triiodothyronine (T3) on the chondrogenic differentiation of female rat bone marrow mesenchymal stem cells (BMMSCs) over several time periods and at several doses. METHODS: CD54 + /CD73 + /CD90 +  BMMSCs from Wistar female rats were cultured in chondrogenic medium with or without T3 (0.01; 1; 100; 1000 nm). At seven, 14 and 21 days, the cell morphology, chondrogenic matrix formation and expression of Sox9 and collagen II were evaluated. KEY FINDINGS: The dose of 100 nm did not alter the parameters evaluated in any of the periods studied. However, the 0.01 nm T3 dose improved the chondrogenic potential by increasing the chondrogenic matrix formation and expression of Sox9 and collagen II in at least one of the evaluated periods; the 1 nm T3 dose also improved the chondrogenic potential by increasing the chondrogenic matrix formation and the expression of collagen II in at least one of the evaluated periods. The 1000 nm T3 dose improved the chondrogenic potential by increasing the chondrogenic matrix formation and Sox9 expression in at least one of the evaluated periods. CONCLUSIONS: T3 has a dose-dependent effect on the differentiation of BMMSCs from female rats.

RESUMO

Resumo A partir de um retrato da situação atual do abortamento inseguro e de uma breve reconstrução das lutas feministas pela descriminalização do aborto no Brasil, o trabalho discute o papel do constitucionalismo democrático no reconhecimento de novos sujeitos de direitos sexuais e reprodutivos. Recorremos ao fundamento político-filosófico dos direitos sexuais e reprodutivos para apontar que sua regulamentação jurídica só tem validade se os "sujeitos de direitos" construídos e pressupostos por sua regulamentação não se prestarem à violação dos postulados fundamentais do constitucionalismo democrático. Tal violação ocorre quando as relações de inclusão e exclusão estabelecidas por seus contornos hipotéticos se prestam a negar reconhecimento institucional à plena dignidade de experiências identitárias dissidentes. Propomos a utilização da teoria de Rosenfeld em pesquisas sobre direito ao aborto sob a perspectiva do Direito Constitucional. Esta teoria permite ver como os discursos sobre direitos criam e enunciam seus sujeitos com marcas de gênero, e podem servir tanto à ampliação das liberdades como de formas de subordinação.

Resumen A partir de un retrato de la situación actual del aborto clandestino y de una breve reconstrucción de las luchas feministas por la despenalización del aborto en Brasil, este trabajo discute el rol del constitucionalismo democrático en el reconocimiento de nuevos sujetos de derechos sexuales y reproductivos. Recurrimos al fundamento político-filosófico de los derechos sexuales y reproductivos para sugerir que su reglamentación jurídica sólo puede tener validez si los "sujetos de derechos" construidos y presupuestos por dicha reglamentación no son utilizados como instrumento para la violación de los postulados fundamentales del constitucionalismo democrático. Esto ocurre cuando las relaciones de inclusión y exclusión establecidas por sus contornos hipotéticos sirven para negar reconocimiento institucional a la plena dignidad de experiencias de identidad disidentes. Sugerimos la utilización de la teoría de Rosenfeld en investigaciones sobre derecho al aborto bajo la perspectiva del derecho constitucional. Esta teoría permite mostrar cómo los discursos sobre derechos crean y enuncian sus sujetos con marcas de género y pueden servir tanto a la ampliación de las libertades como o a formas de subordinación.

Abstract After a brief portrayal of the situation of unsafe abortion in Brazil and the feminist struggles for the decriminalization of abortion, this paper discusses the role of democratic constitutionalism in the acknowledgment of new subjects of sexual and reproductive rights. I resort to the political and philosophical basis of sexual and reproductive rights to suggest that the legal regulation can only be considered valid if the "legal subjects" constructed and presupposed by those regulations do not violate the basic grounds of democratic constitutionalism. This happens whenever the relations of inclusion and exclusion posed by their hypothetical contours deny institutional acknowledgment for the experience dissident identities. I suggest the employment of Rosenfeld's theory for researching abortion rights on a constitutional perspective. This theory provides a tool to show how discourses about rights create and enunciate gendered subjects, and they may work to either expand freedom, or enhance forms of subordination.

RESUMO

Uterine leiomyosarcoma is an uncommon pathology, predominantly found in aged population. Patients with metastatic disease have poor survival and therapy mainly consists of palliative systemic chemotherapy. However, more aggressive strategies such as radiofrequency ablation (RFA) may benefit patients with limited secondary disease. RFA is considered a simple and safe modality for treatment of hepatic lesions. The benefits related to RFA include low morbidity, short hospital stay and the possibility to repeat the procedure when necessary due to recurrences. However, minor and major complications related to mechanical and thermal damage may occur, especially in cases of tumors adjacent to extrahepatic organs and those at subcapsular position. This case report shows a successful RFA of two hepatic subcapsular leiomyosarcoma metastases neighbouring the gallbladder, without a safe cleavage plane from it. Combined hydrodissection, percutaneous cholecystostomy and continuous irrigation were performed as effective techniques to prevent thermal injury. Clinical and radiological follow up demonstrates no local complication.

RESUMO

PURPOSE: To report a novel modified occlusion balloon technique to treat biliary leaks. METHODS: A 22-year-old female patient underwent liver transplantation with biliary-enteric anastomosis. She developed thrombosis of the common hepatic artery and extensive ischemia in the left hepatic lobe. Resection of segments II and III was performed and a biliary-cutaneous leak originating at the resection plane was identified in the early postoperative period. Initial treatment with percutaneous transhepatic drainage was unsuccessful. Therefore, an angioplasty balloon was coaxially inserted within the biliary drain and positioned close to the leak. RESULTS: The fistula output abruptly decreased after the procedure and stopped on the 7th day. At the 3-week follow-up, cholangiography revealed complete resolution of the leakage. CONCLUSION: This novel modified occlusion balloon technique was effective and safe. However, greater experience and more cases are necessary to validate the technique.

RESUMO

O artigo aborda a adoção de medidas de retaliação, através de direitos compensatórios, à prática de subsídios no comércio agrícola internacional, por meio da análise da evolução das diferenças comerciais submetidas à Organização Mundial de Comércio (OMC). Os resultados revelam que os Estados Unidos da América e a União Europeia são os membros que mais sofrem medidas de retaliação na OMC, em razão dos impactos de suas políticas de subsídios ao setor agrícola. Além disso, houve uma queda nos contenciosos comerciais submetidos à apreciação da OMC, especialmente em matéria de direitos compensatórios em relação ao setor agrícola.

This article analyzes the adoption of retaliatory measures, based on countervailing measures, on the practice of subsidies in international agricultural trade, by means of a survey on the evolution of trade differences submitted to the World Trade Organization (WTO). It was possible to identify the United States and the European Union as the members who most suffer from retaliation in the WTO, because of the impacts of their policies on subsidies on the agricultural sector. However, there was a drop in trade disputes submitted to WTO, especially with regard to countervailing measures related to the agricultural sector.

RESUMO

O presente artigo analisa a prática de subsídios à agricultura no comércio internacional, tendo como principal objetivo dimensionar a sua prática enquanto instrumento econômico estratégico para o setor agrícola, especialmente para os Estados Unidos e a União Europeia. Uma completa proibição dos subsídios não é desejável porque sua prática, em essência, constitui uma alternativa à busca do bem-estar social da nação. Contudo, a utilização dos subsídios agrícolas, na forma como vêm sendo praticados, constituem-se em intervenções de cunho protecionista que provocam distorções no comércio internacional. Sendo os Estados Unidos e a União Europeia as nações que mais os utilizam no comércio internacional, tem-se gerado preocupações sobre sua própria eficiência enquanto instrumento de política comercial estratégica para o comércio internacional.

This study examines the practice of agricultural subsidies in international trade, aiming at scaling its practice as a strategic economic tool primarily for the agricultural sector, especially to the United States and the European Union. A complete ban on subsidies is not desirable because its practice, in essence, is a path to improve the welfare of the nation. However, the way the agricultural subsidies have been employed, constitute protectionist interventions that distort international trade. The United States and the European Union are the major users of this instrument in international trade, a factor that has raised concerns about their own efficiency as a strategic trade policy for international trade.

RESUMO

O nanismo hipofisário é uma condição rara caracterizada pela deficiência congênita do hormônio docrescimento (GH). No Pastor Alemão, a doença é transmitida por um gene autossômico recessivo e podeocorrer de forma isolada ou em conjunto com a deficiência de outros hormônios da adenohipófise. Opresente trabalho relata a evolução clínica de um cão pastor alemão com deficiência combinada de hormônioshipofisários. Além da estatura reduzida, o cão demonstrava retardo no desenvolvimento mental,macroglossia, pelagem de filhote e persistência dos dentes decíduos. As alterações bioquímicas incluíramhipercolesterolemia e hipertrigliceridemia. As dosagens séricas de IGF-1 (5,0 nmol/L referência 4,0 a95,0), Tiroxina total (1,9 ng/mL referência 15 a 30), Tiroxina livre por diálise de equilíbrio (0,04 ng/dL –referência 0,08 a 3,0) e Tireotropina (TSH) (0,05 ng/ml referência 0,05 a 0,5) confirmaram o diagnósticode nanismo pituitário e hipotireoidismo secundário. Apesar do tratamento com hormônio tireoidiano, aausência de reposição do hormônio do crescimento resultou na progressão da doença e desenvolvimentode apatia, alopecia generalizada e hipotonia dérmica. Deficiências combinadas de GH e TSH já foramdescritas no Pastor Alemão em outros países, mas este parece ser o primeiro caso relatado no Brasil.(AU)

Pituitary dwarfism is a rare condition characterized by congenital deficiency of growth hormone (GH).In the German shepherd, GH deficiency is transmitted by an autosomal recessive gene and can occurisolated or combined with other pituitary hormones deficiencies. The present study describes the clinicalcourse of a German shepherd dog with combined pituitary hormone deficiency. Besides the stuntedgrowth, the dog showed delayed mental development, macroglossia, puppy hair coat and persistence ofdeciduous teeth. Biochemical abnormalities included hypercholesterolemia and hypertriglyceridemia.The serum levels of IGF-1 (5.0 nmol / L - reference 4.0 to 95.0), total thyroxine (1.9 ng / mL - reference15 to 30), free thyroxine by equilibrium dialysis (0, 04 ng / dL - reference 0.08 to 3.0) and thyrotropin(TSH) (0.05 ng / ml - reference 0.05 to 0.5) confirmed the diagnosis of pituitary dwarfism and secondaryhypothyroidism. Despite the thyroid hormone replacement, the absence of growth hormone treatmentresulted in disease progression and development of generalized alopecia and hypotonic skin. Combineddeficiencies of GH and TSH have been described in the German Shepherd in other countries, but thisseems to be the first report in Brazil.(AU)
