ABSTRACT

Background:The co-existence of diabetes mellitus (DM) and hypertension (HTN) has been rising globally with subclinical atherosclerotic complications. These vascular changes can be detected using carotid ultrasonography. Objectives: To determine and compare the carotid arterial structural wall changes and blood flow velocities of adults with co-existing DM and HTN with age-and sex-matched non-diabetic, non-hypertensive controls. Methods: A cross-sectional comparative study of 300 participants comprising 200 adults with co-existing DM and HTN and 100 age-and sex-matched controls was done. Their carotid arteries were examined bilaterally for plaques, carotid intima media thickness (CIMT) and flow velocities ­peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI) and resistive index (RI) using 4­12MHz linear array transducer. Visceral obesity and serum lipids were also assessed. Results: The mean age of the subjects was 56.13 ± 6.93 years; they comprised 38% males and 62% females. The subjects' CIMT was statistically significantly higher (p = 0.001) with a three-fold mean increase (45.5%) compared to the controls (13.7%). Lower flow velocities but higher indices were also observed in the subjects. Strong and significant correlations were observed between EDV and PI r =-0.663, p=>0.001), EDV and RI (r = -0.661, p=>0.001) and PI and RI (r =0.988, p= >0.001)among the subjects. Conclusion: Significant reduction in flow velocities with increased CIMT may be an early indication of subclinical atherosclerosis. Therefore, carotid ultrasonography should be mandatory in individuals at risk for early detection and possible prevention of atherosclerotic complications.

ABSTRACT

Objetivo: Determinar los hallazgos por eco-Doppler orbitario en pacientes con glaucoma primario de ángulo abierto según factores de riesgo aterosclerótico. Métodos: Se realizó un estudio observacional descriptivo y transversal en 300 órbitas de 150 pacientes con diagnóstico de glaucoma primario de ángulo abierto. A todos los casos se les realizó tonometría de contorno dinámico y tomografía de coherencia óptica. Se identificaron mediante interrogatorio y por el laboratorio clínico los factores de riesgo aterosclerótico: hipertensión arterial, tabaquismo, diabetes mellitus tipo 2, dislipidemia, obesidad y consumo excesivo de alcohol. Se les realizó ultrasonido orbitario y Doppler carotídeo, y solo en caso de resultar normales se procedió a evaluar mediante eco-Doppler las arterias oftálmica, central de la retina y ciliares posteriores temporales. Resultados: La edad media de los sujetos estudiados fue de 62,3 años. El 55,3 por ciento correspondió al sexo femenino y el 47,3 por ciento al color blanco de la piel. El número de factores de riesgo mostró una correlación lineal moderada, positiva y significativa con el índice de resistencia, mientras que con las velocidades dicha correlación resultó ser negativa. Todos los factores de riesgo expresaron efectos dañinos sobre la hemodinámica del flujo ocular, la presión intraocular y el grosor de las capas de fibras neurorretinianas temporales. Tras ajustar para la edad, esta negativa influencia continuó siendo relevante en la mayoría de los casos. Conclusiones: Los aspectos vasculares del glaucoma deben integrarse a la práctica clínica de esta afección, lo que ayudará a que el enfoque sea más completo, y redundará en un mejor pronóstico de la enfermedad(AU)


Objective: Determine the orbital echo-Doppler findings in patients with primary open angle glaucoma according to atherosclerotic risk factors. Methods: A cross-sectional observational descriptive study was conducted of 300 orbits of 150 patients diagnosed with primary open angle glaucoma. All the cases underwent dynamic contour tonometry and optical coherence tomography. Interrogation and clinical laboratory testing led to identification of the following atherosclerotic risk factors: arterial hypertension, smoking, diabetes mellitus type 2, dyslipidemia, obesity and excessive alcohol consumption. Orbital and carotid Doppler ultrasounds were performed, and only if they were normal they would be followed by echo-Doppler evaluation of the ophthalmic, central retinal and posterior temporal ciliary arteries. Results: Mean age of the study subjects was 62.3 years. 55.3 percent were female and 47.3 percent had white skin. The number of risk factors showed a moderate, positive and significant linear correlation with the resistive index, and a negative correlation with the velocities. All the risk factors expressed harmful effects on ocular flow hemodynamics, intraocular pressure and the thickness of temporal neuroretinal fibers. After adjusting for age, this negative influence continued to be relevant in most cases. Conclusions: The vascular aspects of glaucoma should be incorporated into the clinical management of this condition. This will make the approach more thorough and help achieve a better diagnosis(AU)

ABSTRACT

The doppler-guided transanal hemorrhoidal dearterialization technique associated with mucopexy is a noninvasive surgical option used to treat hemorrhoidal disease (HD). Objective: To compare and analyze the results using a variation of the doppler-guided transanal hemorrhoidal dearterialization technique with the technique of selective hemorrhoidal dearterialization with high mucopexy in the treatment of HD. Method: A total of 292 patients who underwent surgical treatment for grade II, III and IV HD from March 2012 to December 2017 were studied. From this total, 110 (37.6%) patients underwent a conventional doppler-guided transanal hemorrhoidal dearterialization with mucopexy (CD), and 182 (62.3%) underwent selective hemorrhoidal dearterialization with highmucopexy (SHeLF). In the group of patients undergoing CD, 4 patients (3.64%) had grade II HD, 82 (74.55%) grade III, and 24 (21.82%) grade IV. In the group submitted to SHeLF, 18 (9.89%) patients had grade II HD, 86 (47.25%) had grade III, and 65 (35.71%) had grade IV. The same surgeon operated all patients under spinal anesthesia. In patients undergoing CD, six arterial branches have been dearterialized, while in patients undergoing SHeLF, the hemorrhoidary nipples submitted to a dearterialization were selected (from 1 to 5) by intraoperative evaluation followed by high rectal mucopexy. In the postoperative period, the following parameters were evaluated: pain, tenesmus, bleeding, and recurrence. Moderate results to severe pain was a postoperative complaint reported by 13 (11.82%) patients undergoing CD, and by 19 (10.44%) undergoing SHeLF. Intense tenesmus was reported by 26 (23.64%) patients undergoing CD and by 7 (3.85%) undergoing SHeLF. Three patients (2.73%) undergoing CD and 1 (0.55%) undergoing SHeLF evolved with postoperative bleeding. One patient (0.55%) in the group undergoing CD required surgical review of hemostasis. Six patients (5.45%) who underwent CD and 8 (4.39%) who underwent SHeLF were reoperated due to disease recurrence. Conclusion: Comparing statistics, patients undergoing the SHeLF technique have less postoperative pain, tenesmus and postoperative bleeding when compared with CD. (AU)

ABSTRACT

This study used B-mode and Doppler ultrasonography to characterize the abdominal structures of healthy peccaries raised in captivity. Fifteen peccaries were used for this study. The urinary vesicle appeared as an ovoid structure, located in the abdominal and pelvic transition, with a hyperechogenic, thin, smooth, and regular wall. The kidneys presented retroperitoneal topography and had similar sizes. The kidney/aorta ratio had an average value of 10.53±15cm (right) and 10.23±0.12 (left). The right adrenal gland had a length of 1.93±0.34cm and diameter of 0.56±0.16cm. The left adrenal gland had a length of 1.85±0.42cm and diameter of 0.52±0.11cm. The spleen had a diameter of 1.13±0.18cm. The hepatic vein demonstrated polyphasic flow in pulsed Doppler, with two retrograde peaks and an anterograde peak with a flow velocity of 25.7±0.83cm/s. The abdominal aorta had a diameter of 0.58±0.05cm and a flow velocity of 115.17±5.32cm/s. The morphological and hemodynamic study of the abdominal structures of the peccary, observed through B-mode and Doppler ultrasonography, aided in identifying the size, shape, position, echogenicity, and echotexture of the abdominal organs and in making inferences about the normal parameters for these structures in this species.(AU)


Este estudo teve como objetivo utilizar as ultrassonografias de modo-B e Doppler para caracterizar as estruturas abdominais de um cateto sadio criado em cativeiro. Quinze catetos foram utilizados para este estudo. A vesícula urinária apareceu como uma estrutura ovoide, localizada na transição entre as partes abdominal e pélvica, com uma parede hiperecogênica, fina, lisa e regular. Os rins apresentaram topografia retroperitoneal e tamanhos semelhantes. A relação rim/aorta teve um valor médio de 10,53 ± 15cm (direita) e 10,23 ± 0,12cm (esquerda). A glândula adrenal direita tinha um comprimento de 1,93 ± 0,34cm e um diâmetro de 0,56 ± 0,16cm. A glândula suprarrenal esquerda tinha um comprimento de 1,85 ± 0,42cm e um diâmetro de 0,52 ± 0,11cm. O baço tinha um diâmetro de 1,13 ± 0,18cm. A veia hepática demonstrou fluxo polifásico no Doppler pulsátil, com dois picos retrógrados e um pico anterógrado com velocidade de fluxo de 25,7±0,83cm/s. A aorta abdominal tinha um diâmetro de 0,58 ± 0,05cm e uma velocidade de fluxo de 115,17±5,32cm/s. Os estudos morfológico e hemodinâmico das estruturas abdominais do queixada, observadas por meio das ultrassonografias modo-B e Doppler, auxiliaram na identificação do tamanho, da forma, da posição, da ecogenicidade e da ecotextura dos órgãos abdominais e na realização de inferências sobre os parâmetros de normalidade para as estruturas nas espécies.(AU)

ABSTRACT

Introdução: A iatrogenia é uma causa importante de morbimortalidade, logo, a prevenção quaternária (P4), ação que ceifa a cascata diagnóstica supérflua, foi incluída como exercício de boa prática. A medicina de família e comunidade (MFC) introjeta a P4 na vivência, sendo capaz de usar ciência aliada a habilidades de comunicação para conhecer as pessoas, resolvendo assim cerca de 85% das queixas, o que inclui as de origem vascular. Existe uma alta demanda no Sistema Único de Saúde (SUS) tanto na marcação de exames quanto no encaminhamento para especialistas focais no que tange às queixas circulatórias, mas nem sempre encaminhar é oportuno. Nesse cenário, a MFC funciona como um caminho para a P4. Objetivos: O objetivo do presente estudo foi avaliar as referências para cirurgia vascular e angiologia e as solicitações de ultrassonografia (USG) Doppler de vasos de unidades de saúde da família (USFs) de João Pessoa/PB, analisando as taxas de solicitações por população adulta (>18 anos) adscrita, nas unidades conveniadas ao programa de residência em medicina de família e comunidade (PRMFC) há mais de 1 ano, há menos de 1 ano e naquelas sem convênio com PRMFC, sob o olhar crítico da P4. Métodos: Trata-se de um estudo transversal a partir de dados fornecidos pela Central de Regulação da Secretaria Municipal de Saúde de João Pessoa (SMS/JP), entre janeiro de 2017 e agosto de 2018. Para realização dos cálculos de correlação entre as variáveis estudadas, utilizou-se o teste de Kruskall-Wallis através do software SPSS 21.0. Resultados: O número total de pedidos de exames em análise foi de 3.918, oriundos de 90 USF, que somam uma população adscrita maior de 18 anos de 332.819 pessoas. Solicitou-se 1 Doppler a cada 85 habitantes adultos. Os resultados do estudo sugerem que os médicos residentes solicitam mais exames que os médicos não residentes, mas por outro lado apresentam menor taxa de encaminhamento aos especialistas. Conclusões: Estes achados podem sugerir que os médicos residentes encaminham menos, o que pode estar relacionado ao aumento da resolubilidade da atenção primária à saúde (APS) e ao ensino da P4 sob orientação de um médico de família e comunidade preceptor. Entretanto, novos delineamentos de pesquisa são necessários para melhor elucidar esta hipótese.


Introduction: Iatrogenesis is an important cause of morbimortality and quaternary prevention (P4), an action that reduces the superfluous diagnostic cascade, was included as an exercise of good practice. Family practice projects P4 into practice, being able to use science combined with communication skills to know people, solving about 85% of complaints, including vascular discomforts. There is a high demand at Sistema Único de Saúde (SUS) both in scheduling exams and referrals to focal specialists with regard to circulatory complaints, but referring is not always appropriate. In this scenario, family practice works as a pathway to P4. Objectives: The aim of the present study was to evaluate the referrals for vascular surgery/angiologist and requests for Doppler ultrasonography (USG) of vessels from family health units (USF) in João Pessoa, PB, analyzing the rates of requests per registered adult population (>18-years-old) in the units affiliated to the family practice medical residency program (FPMRP) for more than a year, less than a year and in the non-affiliated ones, under P4's critical view. Methods: This is a cross-sectional study of data provided by the Regulation Center of the Municipal Health Department of João Pessoa, between January 2017 and August 2018. To perform the correlation calculations between the studied variables, Kruskall-Wallis' correlation test was used through the SPSS 21.0 software. Results: The total number of exam requests under analysis was 3,918, from 90 USF, which add up to an enrolled population over 18-years-old of 332,819 people. For every 85 adult inhabitants, one Doppler exam was requested. Data suggest that the resident doctors request more exams than the non-residents, but on the other hand they have lower rates of referrals to focal experts. Conclusions: These findings may suggest that resident physicians refer less, which may be related to the increase in the resolution of primary care and the teaching of P4 under the guidance of a family practice preceptor. However, new research designs are considered to better elucidate this hypothesis.


Introducción: La iatrogenia es una causa importante de morbilidad y mortalidad, por lo que se incluyó como ejercicio de buena práctica la prevención cuaternaria (P4), una acción que corta la cascada diagnóstica superflua. La medicina familiar y comunitaria (MFC) introduce la P4 en la práctica, siendo capaz de utilizar la ciencia aliada a las habilidades de comunicación para conocer a las personas, resolviendo así alrededor del 85% de las quejas, lo que incluye las quejas vasculares. En el Sistema Único de Salud (SUS) brasileño hay una gran demanda, tanto para programar exámenes como para derivar a los especialistas focales las dolencias circulatorias, pero la derivación no siempre es oportuna. En este escenario, la CBM funciona como una vía hacia la P4. Objetivo: El objetivo del presente estudio fue evaluar las referencias de cirugía vascular y angiología y las solicitudes de ultrasonografía Doppler (USG) de vasos de las unidades de salud de la familia (USF) de João Pessoa/PB, analizando las tasas de solicitudes por población adulta (>18 años) asignada, en las unidades asociadas al programa de residencia en medicina de la familia y de la comunidad (CFMRP) por más de 1 año, por menos de 1 año y en las que no tienen convenio con el CFMRP, bajo la visión crítica del P4. Métodos: Se trata de un estudio transversal de datos proporcionados por la Central de Regulación de la Secretaría Municipal de Salud de João Pessoa (SMS/JP), entre enero de 2017 y agosto de 2018. Se utilizó la prueba de Kruskall-Wallis para realizar los cálculos de correlación entre las variables estudiadas mediante el programa informático SPSS 21.0. Resultados: El número total de solicitudes de pruebas analizadas fue de 3.918, procedentes de 90 USF, que suman una población asignada mayor de 18 años de 332.819 personas. Se solicitó un Doppler por cada 85 habitantes adultos. Los resultados sugieren que los médicos residentes solicitan más pruebas que los no residentes, pero por otro lado tienen una tasa de derivación a especialistas más baja. Conclusiones: Estos resultados pueden sugerir que los médicos residentes derivan menos, lo que puede estar relacionado con la mayor resolutividad de la Atención Primaria de Salud (APS) y la enseñanza de la P4 bajo la dirección de un médico de familia y un preceptor comunitario. Sin embargo, se necesitan nuevos diseños de investigación para dilucidar mejor esta hipótesis.

ABSTRACT

The oscillometric monitor is a noninvasive method used for measuring blood pressure in dogs and cats. Despite widely used, there is a large variability in the accuracy of oscillometric monitors, which may also be influenced by the location of the blood pressure cuff. The Doppler ultrasound is another non-invasive method that was shown to measure blood pressure with good accuracy and precision in small animals. The present study aimed to determine the agreement between systolic arterial pressure (SAP) measured by the Prolife P12 oscillometric monitor with 2 cuff locations and the Doppler ultrasound in anesthetized dogs. Dogs scheduled for routine anesthetic procedures were included in the study, which was carried out in 2 phases. In Phase 1, SAP values measured by the Doppler were compared with those measured by the Prolife P12 monitor with the cuff placed at the thoracic limb for both methods. In Phase 2, SAP values measured by the Doppler were compared with those measured by the Prolife P12 monitor, with the cuff placed at the thoracic limb for the Doppler and at the base of the tail for the P12. The cuff width corresponded to approximately 40% of limb or tail circumference. On all occasions, 3 consecutive measurements of SAP were recorded, followed by a single measurement of SAP by the P12, and then other 3 measurements were performed with the Doppler. The arithmetic mean of the 6 SAP measurements with the Doppler was compared with the SAP value measured by the P12 monitor (paired measurements). Agreement between SAP values measured by the Doppler and the P12 monitor was analyzed by the Bland Altman method for calculation of the bias (Doppler - P12) and standard deviation (SD) of the bias. The percentages of differences between the methods with an error ≤ 10 mmHg and ≤ 20 mmHg and Pearson's correlation coefficients were also calculated. Results were compared with the criteria from the American College of Veterinary Internal Medicine (ACVIM) for validation of noninvasive blood pressure methods. A total of 33 dogs were included in Phase 1 and 15 were included in Phase 2. During Phases 1 and 2, 179 and 87 paired measurements were recorded, respectively. Most of the measurements were recorded during normotension (SAP = 90-130 mmHg): 113/179 in Phase 1 and 52/87 in Phase 2. The bias (± SD) for Phases 1 and 2 were -2.7 ± 14.1 mmHg and 7.2 ± 25.8 mmHg. The percentages of differences ≤ 10 mmHg and ≤ 20 mmHg were: Phase 1, 61% and 83%; Phase 2, 41% and 70%. Correlation coefficients were 0.81 and 0.67 for Phases 1 and 2, respectively. According to the ACVIM criteria, maximum values accepted for bias are 10 ± 15 mmHg, the percentages of differences ≤ 10 mmHg and ≤ 20 mmHg should be ≥ 50% and ≥ 80%, respectively, and the correlation coefficient should be ≥ 0.9. When the blood pressure cuff was placed at the thoracic limb, SAP values measured by the P12 monitor met most of the ACVIM criteria, demonstrating good agreement with SAP values measured by the Doppler. The only requirement not met was the correlation coefficient which was 0.81 whereas the recommended is ≥ 0.9. Conversely, when the cuff was placed at the base of the tail, SAP values measured by the P12 monitor did not meet most of the ACVIM criteria indicating that, in anesthetized dogs, SAP measurements with the P12 monitor should be performed with the cuff placed at the thoracic limb. One limitation of this study was that most measurements fell in the normotensive range and the results should not be extrapolated for hypotensive and hypertensive conditions. In conclusion, the Prolife P12 oscillometric monitor demonstrated good agreement with SAP values measured by the Doppler and provides acceptable values in normotensive anesthetized dogs.(AU)

ABSTRACT

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.


RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.

ABSTRACT

Introducción: La malformación aneurismática en la vena de Galeno es infrecuente, pero tiene alta mortalidad en neonatos. Objetivo: Examinar la relevancia clínica del diagnóstico ecográfico de la malformación aneurismática en la vena de Galeno Métodos: Investigación observacional, prospectiva y transversal realizado en el Cardiocentro William Soler. (noviembre 1999-diciembre 2016) La muestra la conformaron 18 neonatos con diagnóstico de malformación aneurismática en la vena de Galeno variedad coroidea mediante ecografía doppler. Se configuraron dos grupos de referencia: 1) 70 niños supuestamente sanos. 2) 73 niños con malformación de la vena Galeno de diferente naturaleza que la variante coroidea estudiada. El procesamiento de la información incluyó elementos de estadística inferencial y herramientas de la medicina basada en la evidencia. Resultados: La presencia de fallo cardíaco neonatal, signos electrocardiográficos de isquemia miocárdica y detección de soplo continuo transcraneal, fueron significativamente diferentes en el grupo de estudio en relación con el grupo de referencia (p= 0,000001), con predominio en el número de pacientes del grupo estudio en todas las variables. Los resultados anteriores conjugados con diversos hallazgos ecográficos: la dilatación anómala de la vena, exceso de vasculatura aferente, reducción de los índices circulatorios encefálicos e incremento en los diámetros vasculares supraaórticos, identificaron de forma precisa la malformación aneurismática en la vena de Galeno. La evaluación del riesgo relativo reafirmó la documentación de los hallazgos expuestos. Conclusiones: La ecografía doppler, por su relevancia clínica y vínculo con otros elementos diagnósticos, es mandatoria en la detección de la malformación aneurismática en la vena de Galeno(AU)


Introduction: Vein of Galen aneurysmal malformation is not frequent but it has high mortality rates in newborns. Objective: To assess the clinical relevance of ultrasound diagnosis of Vein of Galen aneurysmal malformation. Methods: Observational, prospective and cross-sectional research conducted in William Soler Cardiocentro (November 1999- December 2016). The sample was formed by 18 newborns with diagnosis of Vein of Galen aneurysmal malformation (choroidal variety) through doppler echocardiography. Two reference groups were formed: 1) 70 supposedly healthy children; 2) 73 children with Vein of Galen malformation with a nature different to the studied choroidal variety. Processing of the information included elements of inferential statistics and tools from medicine based in evidences. Results: The presence of neonatal heart failure, electrocardiographic signs of myocardial ischemia and detection of transcranial continuous murmur were significantly different in the study group in relation with the reference group (p= 0,000001), with predominance in the number of patients of the study group in all the variables. The previous results combined with different ultrasound findings as the anomalous dilation of the vein, the excess of afferent vasculature, the reduction of encephalic circulation indexes and the increase of the supraaortic vascular diameters identified in a precise way the vein of Galen aneurysmal malformation. The assessment of the relative risk reaffirmed the information on the exposed findings. Conclusions: Doppler echography, due to its clinical importance and its links with other diagnostic elements, is mandatory in the detection of the vein of Galen aneurysmal malformation(AU)

ABSTRACT

The objective of this study was to evaluate the effects of an hCG sub dose applied at the Hou Hai acupoint on corpus luteum (CL) quality and ovulation induction in mares. Fifteen crossbred mares were distributed in randomized blocks and used in three periods with each period employed as the blocking factor in three treatments: T1 = 1500 IU of hCG via intravenous (IV); T2 = 450 IU of hCG applied at the false acupoint (IV); and T3 = 450 IU of hCG applied at the Hou Hai acupoint. Mean diameter of the CL, serum concentration of progesterone (P4), vascularization of the pre-ovulatory follicle and CL were evaluated. Females administered 450 IU of hCG at the Hou Hai acupoint exhibited greater ovulation rates (33.33%) 48h after induction; The minimum number of colored pixel (NCP) of the pre-ovulatory follicle of control females was superior (40.33) to that of mares administered 450 IU of hCG IV at the false acupoint (36.84) and similar to that of those administered hCG at the Hou Hai acupoint (39.31). Further, moderately positive correlations were found between the CL diameter and the P4 concentration on D8 (P<0.05). IV administration of 450 IU of hCG or at the Hou Hai acupoint was efficient at inducing ovulation and ensuring the quality of CL in mares.(AU)


O objetivo foi avaliar os efeitos de uma subdose de hCG aplicada no acuponto Hou Hai na qualidade do corpo lúteo (CL) e na indução da ovulação em éguas. Quinze éguas mestiças foram distribuídas em blocos ao acaso, sendo o período utilizado como fator de blocagem, em: T1 = 1500 UI de hCG por via intravenosa (IV); T2 = 450 UI de hCG aplicado no falso acuponto (IV) e T3 = 450 UI de hCG aplicada no acuponto Hou Hai. Avaliou-se diâmetro médio do CL, concentração sérica de progesterona (P4), vascularização do folículo pré-ovulatório e do CL. As fêmeas que receberam 450 UI de hCG no acuponto Hou Hai apresentaram maiores taxas de ovulação (33,33%) 48h após a indução. O número de pixels coloridos (NPC) mínimo do folículo pré-ovulatório das fêmeas do grupo controle foi superior (40,33) ao das éguas que receberam 450 UI de hCG IV no falso acuponto (36,84) e semelhante ao das éguas que receberam hCG no acuponto Hou Hai (39,31); correlações moderadamente positivas foram encontradas entre o diâmetro do CL e a concentração de P4, ambos no D8 (P <0,05). A administração IV de 450 UI de hCG ou no acuponto Hou Hai foi eficiente na indução da ovulação e na garantia da qualidade do CL nas éguas.(AU)

ABSTRACT

The aim of this study was to assess the applicability of ARFI elastography for the complementary diagnosis of canine prostatic alterations. Twenty-two healthy dogs and 45 with prostatic alterations were diagnosed by the association of general and specific physical exams. Complete blood count, B-mode and Doppler ultrasound were performed. For the elastography study, tissue homogeneity and deformity were verified using the elastogram, and the shear velocities of the left and right lobes of all prostates were obtained. The change in tissue homogeneity was observed in 62.2% of the animals, while the shear speed was significantly higher in dogs with prostatic alterations, with a cut-off point > 2.35m/s as an indication of change. All animals in both groups were non-deformable. It was concluded that ARFI elastography is capable of providing qualitative and quantitative results that assist in the diagnosis of canine prostatic alterations in a non-invasive way.(AU)


O objetivo deste estudo foi avaliar a aplicabilidade da elastografia ARFI na complementação diagnóstica das alterações prostáticas em cães. Foram avaliados 22 cães saudáveis e 45 com alterações prostáticas, diagnosticadas pela associação de exames físicos geral e específico, hemograma, ultrassonografia modo B e Doppler. No estudo elastográfico, foram verificadas a homogeneidade e a deformidade tecidual, pelo elastograma, e obtidas as velocidades de cisalhamento dos lobos esquerdo e direito de todas as próstatas. A alteração de homogeneidade tecidual foi observada em 62,2% dos animais, enquanto a velocidade de cisalhamento se mostrou significativamente maior em cães com alterações prostáticas, com ponto de corte >2,35m/s como indicativo de alteração. Todos os animais de ambos os grupos se apresentaram não deformáveis. Concluiu-se que a elastografia ARFI é capaz de fornecer resultados qualitativos e quantitativos que auxiliam no diagnóstico das alterações prostáticas caninas de forma não invasiva.(AU)

ABSTRACT

Abstract Objective Primary dysmenorrhea occurs due to abnormal levels of prostanoids, uterine contractions, and uterine blood flow. However, the reasons for pain in primary dysmenorrhea have not yet been clarified. We examined the blood flow alterations in patients with primary dysmenorrhea and determined the relationship between ischemia-modified albumin (IMA) levels, as an ischemia indicator, and primary dysmenorrhea. Methods In the present study, 37 patients who had primary dysmenorrhea and were in their luteal and menstrual phase of their menstrual cycles were included. Thirty individuals who had similar demographic characteristics, who were between 18 and 30 years old and did not have gynecologic disease were included as control individuals. Their uterine artery Doppler indices and serum IMA levels were measured. Results Menstrual phase plasma IMA levels were significantly higher than luteal phase IMA levels, both in the patient and in the control groups (p < 0.001). Although the menstrual phase IMA levels of patients were significantly higher than those of controls, luteal phase IMA levels were not significantly different between the two groups. Menstrual uterine artery pulsatility index (PI) and resistance index (RI) of primary dysmenorrhea patients were significantly different when compared with luteal uterine artery PI and RI levels. There was a positive correlation between menstrual phase IMA and uterine artery PI and RI in the primary dysmenorrhea. Conclusion Ischemia plays an important role in the etiology of the pain, which is frequently observed in patients with primary dysmenorrhea. Ischemia-modified albumin levels are considered as an efficient marker to determine the severity of pain and to indicate ischemia in primary dysmenorrhea.

ABSTRACT

The objectives of this study were to characterize the endometritis induced in mares using color Doppler ultrasonography and traditional exams. Experiment 1. Mares (n=20) were submitted to intrauterine inoculation with Escherichia coli. Uterine evaluation was performed at M0 and M1. Experiment 2. Animals were divided into two groups: control group (n=10), and treated group (n=10) using phytotherapeutic solution. In both groups, the uterine evaluation was performed at time T1, T2, and T3. Experiment 3: Uterine evaluation was compared after antibiotic therapy, phytotherapy, and M0. For statistical analysis, the Tukey test, t Student, and Anova test were applied. Experiment 1. The mean values of vascularization at M1 were significantly higher than those obtained at M0 (P<0.05). Bacterial growth was observed in all samples collected. Experiment 2. The mean value of vascularization at time T1 in both groups was significantly higher (P<0.05) compared to M2 and M3. Experiment 3. After antibiotic therapy, the vascularization of the body and uterine horns was not equivalent to the vascularization presented at M0. We can conclude that it was not possible to correlate results obtained by color Doppler ultrasonography with the traditional findings for the diagnosis of endometritis.(AU)


Os objetivos deste estudo foram caracterizar a endometrite induzida em éguas utilizando-se a ultrassonografia com Doppler colorido e exames tradicionais. Experimento 1: as éguas (n=20) foram submetidas à inoculação intrauterina com Escherichia coli. A avaliação uterina foi realizada em M0 e M1. Experimento 2: os animais foram divididos em dois grupos: grupo controle (n=10) e grupo tratado (n=10), sendo usada solução fitoterápica. Nos dois grupos, a avaliação uterina ocorreu nos momentos T1, T2 e T3. Experimento 3: a avaliação uterina foi comparada após antibioticoterapia, fitoterapia e M0. Para análise estatística, foram aplicados os testes de Tukey, t de Student e ANOVA. Experimento 1: os valores médios de vascularização em M1 foram significativamente maiores que os obtidos no M0 (P<0,05). Houve crescimento bacteriano em todas as amostras coletadas. Experimento 2: o valor médio da vascularização no tempo T1 nos dois grupos foi significativamente maior (P<0,05) do que o obtido em M2 e M3. Experimento 3: após antibioticoterapia, a vascularização do corpo e dos cornos uterinos não era equivalente à vascularização apresentada em M0. Pode-se concluir que não foi possível correlacionar os resultados obtidos pela ultrassonografia com Doppler colorido com os achados tradicionais para o diagnóstico de endometrite.(AU)

ABSTRACT

Abstract Objective The aim of the present study was to compare the obstetric history and both two- and tri-dimensional ultrasound parameters according to different cervical lengths. Methods The present cross-sectional study analyzed 248 midtrimester pregnant women according to cervical length and compared the data with the obstetric history and 2D/3D ultrasound parameters. Patients were divided into 3 groups according to cervical length: The Short Cervix group for cervical lengths ≥ 15mm and< 25mm(n= 68), the Very Short Cervix group for cervical lengths< 15mm (n = 18) and the Control group, composed of 162 pregnant women with uterine cervical lengths ≥ 25mm. Results When analyzing the obstetric history of only non-nulliparous patients, a significant association between the presence of a short cervix in the current pregnancy and at least one previous preterm birth was reported (p = 0.021). Cervical length and volume were positively correlated (Pearson coefficient = 0.587, p < 0.0001). The flow index (FI) parameter of cervical vascularization was significantly different between the Control and Very Short Cervix groups. However, after linear regression, in the presence of volume information, we found no association between the groups and FI. Uterine artery Doppler was also not related to cervical shortening. Conclusion The present study showed a significant association between the presence of a short cervix in the current pregnancy and at least one previous preterm birth. None of the vascularization indexes correlate with cervical length as an independent parameter. Uterine artery Doppler findings do not correlate with cervical length.


Resumo Objetivo O objetivo do presente estudo foi comparar a história obstétrica e os parâmetros bi- e tridimensionais ultrassonográficos de acordo com os diferentes comprimentos cervicais. Métodos O presente estudo transversal analisou 248 gestantes no segundo trimestre de acordo com o comprimento cervical e comparou os dados com a história obstétrica e os parâmetros ultrassonográficos 2D/3D. As pacientes foram divididas em 3 grupos de acordo com o comprimento do colo uterino: grupo Colo Curto para comprimentos cervicais ≥ 15mm e < 25mm (n = 68), grupo Colo Muito Curto para comprimentos cervicais < 15mm (n = 18) e grupo Controle, composto por 162 gestantes com comprimento cervical uterino ≥ 25 mm. Resultados Ao analisar a história obstétrica apenas de pacientes não nulíparas, foi relatadauma associação significativa entre a presença de colo uterino curto na gravidez atual e pelo menos um episódio de parto prematuro anterior (p = 0,021). Comprimento e volume do colo uterino foram correlacionados positivamente (coeficiente de Pearson = 0,587, p < 0,0001). O parâmetro índice de fluxo (IF) da vascularização cervical foi significativamente diferente entre os grupos Controle e Colo Muito Curto. Entretanto, após regressão linear, na presença de informações de volume, não encontramos associação entre os grupos e o parâmetro IF. Também não foi encontrada relação entre o Doppler da artéria uterina e o encurtamento cervical. Conclusão O presente estudo mostrou uma associação significativa entre a presença de colo uterino curto na gravidez atual e pelo menos um episódio de parto prematuro anterior. Nenhum dos índices de vascularização se correlaciona com o comprimento cervical como parâmetro independente, assim como o Doppler da artéria uterina também não está relacionado ao comprimento do colo uterino.
