Clinical, laboratory, ultrasonographic, and anatomopathological aspects of 30 cases of traumatic reticulosplenitis in cattle / Aspectos clínicos, laboratoriais, ultrassonográficos e anatomopatológicos de 30 casos de reticulo-esplenite traumática em bovinos

Ingestion of metallic and/or sharp foreign bodies triggers cases of traumatic reticuloperitonitis and its sequelae in cattle. Among these sequelae, we can highlight traumatic reticulosplenitis, that has high mortality, although its frequency in the ruminant medicine is low. Therefore, based on the scarcity of information on this disease, the current study aimed to evaluate the clinical, laboratory, ultrasonographic, and pathological findings of 30 adult cattle diagnosed with traumatic reticulosplenitis. Clinical, ultrasound, and anatomopathological findings were analyzed using descriptive statistics and laboratory data were evaluated using measures of central tendency. Clinically the animals presented dehydration and alterations in behavior, appetite, and ruminal motility. Hematological findings revealed neutrophilic leukocytosis (37077.17±25004.59cell/µL) with regenerative left shift and hyperfibrinogenemia (1130±364.98mg/dL). The ultrasound examination enabled visualization of mobile and echogenic filaments that corresponded to the presence of fibrin adhesions. Displacement of the reticulum and irregularity in its contour, as well as alterations in the quantity, pattern, and amplitude of reticular contractions were also observed. Splenic alterations such as abscesses were found, characterized as circular structures of varying sizes delimited by capsules containing variable echogenicity. Splenic vein thrombosis and spleen folding were also observed. The results obtained in the current study indicated that traumatic reticulosplenitis causes nonspecific clinical signs, severe laboratory alterations and, mainly, that ultrasound is an efficient method for the diagnosis of this disease, since the anatomopathological lesions confirmed the ultrasound findings.(AU)

A ingestão de corpos estranho de origem metálica e/ou pontiagudos desencadeia em bovinos, quadros de Reticuloperitonite Traumática e suas sequelas. Dentre as quais podemos destacar a retículo esplenite traumática cuja letalidade é elevada, embora a mesma apresente uma baixa frequência na clínica de ruminantes. Portanto, baseado na escassez de informações sobre esta enfermidade, este trabalho teve por objetivo avaliar os achados clínicos, laboratoriais, ultrassonográficos e anatomopatológicos de 30 bovinos adultos diagnosticados com retículo esplenite traumática. Os achados clínicos, ultrassonográfico e anatomopatológico foram analisados por meio de estatística descritiva, e os dados laboratoriais foram avaliados utilizando-se as medidas de tendência central. Clinicamente os animais apresentaram desidratação e alterações no comportamento, apetite e na motilidade ruminal. Os achados hematológicos revelaram leucocitose (37077.17±25004.59cell/µL) por neutrofilia com desvio à esquerda regenerativo e hiperfibrinogenemia (1130±364.98mg/dL). O exame ultrassonográfico possibilitou a visualização de filamentos móveis e ecogênicos que corresponderam à presença de aderências fibrinosas, observou-se também, deslocamento do retículo e irregularidade no seu contorno além das alterações na quantidade, padrão e amplitude das contrações reticulares. Permitiu ainda, a constatação de alterações esplênicas como abscessos que foram caracterizados como estruturas circulares de variados tamanhos delimitada por capsula contendo no seu interior conteúdo de ecogenicidade variável. Trombose da veia esplênica e dobramento do baço. Os resultados obtidos nesse trabalho, indicaram que a retículo esplenite traumática causa sinais clínicos inespecíficos, severas alterações laboratoriais e principalmente que a ultrassonografia é um método eficiente para o diagnóstico dessa enfermidade uma vez que as lesões anatomopatológicas confirmaram os achados ultrassonográficos.(AU)

Ascitis fetal como manifestación de peritonitis meconial; presentación de un caso y revisión de literature / Fetal ascites as a manifestation of meconium peritonitis; presentation of a case and literature review

RESUMEN Introducción: La peritonitis meconial (PM) corresponde a una inflamación del peritoneo por una reacción química estéril producida por la presencia de meconio, secundaria a una perforación intestinal in útero. Se expone un caso real de PM cuya relevancia está dada por la baja incidencia de esta enfermedad, siendo de aproximadamente 1 caso por cada 30.000 nacidos vivos. El presente trabajo tiene como objetivo dar a conocer la presentación clásica de la PM mediante una revisión actualizada de la literatura. Caso clínico: Paciente de 21 años, primigesta, cursando embarazo de 33 + 5 semanas, con antecedentes de hipotiroidismo gestacional, es derivada al servicio de urgencia maternal por hallazgo en ecografía realizada ese mismo día: Ascitis fetal, intestino hiperecogénico, sin alteraciones en eco-Doppler fetal, hospitalizándose a paciente para estudio. Los exámenes de laboratorio, incluidos VIH y VDRL, resultaron negativos y no esclarecían una etiología. Dado hallazgos ecográficos posteriores se logra orientar el diagnóstico hacia una PM, la cual se objetivó una vez interrumpido el embarazo a la semana 38+5. Discusión: La PM representa un desafío para el médico tanto en su diagnóstico como tratamiento, lo cual está dado en parte por su baja incidencia. El caso expone la presentación más clásica de la PM, en la cual se logró establecer la importancia del diagnóstico prenatal y como este influye en el pronóstico y manejo posterior. Existe acuerdo en adoptar una conducta expectante frente a la PM e incluso esperar el inicio del parto espontaneo, si no existen otras contraindicaciones.

ABSTRACT Introduction: Meconial peritonitis (MP) corresponds to an inflammation of the peritoneum due to a sterile chemical reaction produced by the presence of meconium, secondary to a intestinal perforation in utero. We present a real case of MP whose relevance is given by the low incidence of this disease, being approximately 1 case per 30,000 live births. The present work has as objective to present the classic presentation of the MP through an updated literature review. Clinical case: A 21-year-old woman, primigravous, with a pregnancy of 33 + 5 weeks, and a history of gestational hypothyroidism, is referred to the maternal emergency service due to the following finding on ultrasound performed that same day: Fetal ascites, hyperechogenic bowel, without alterations in fetal echo-Doppler. Patient is hospitalized for study. Laboratory tests, including HIV and VDRL, were negative and did not clarify an etiology. Given later sonographic findings, the diagnosis is oriented towards MP, which was observed once the pregnancy was interrupted at week 38 + 5. Discussion: MP represents a challenge for the physician both in diagnosis and treatment, which is partly due to its low incidence. The case presents the most classic presentation of the MP, in which it was possible to establish the importance of prenatal diagnosis and how it influences the prognosis and subsequent management. There is agreement to adopt an expectant behavior towards MP and even wait for the start of spontaneous birth, if there are no other contraindications.

Extranasal T/NK-cell lymphoma presenting as intestinal diverticulum

A case of intestinal angiocentric T/NK-cell lymphoma in a 58-year-old man is reported. The patient presented initially with panperitonitis because of perforation of sigmoid colon diverticulum. He underwent segmentectomy of involved bowel. Histologically, the intestinal wall showed diffuse infiltration of medium or large size lymphoma cells with angiocentric growth and necrosis. The lymphoma cells were CD56+, CD45RO+, CD3+, CD4-, CD8-, CD20-, and CD30- in paraffin sections with germline configuration of TCR-gamma gene, consistent with T/NK-cell lymphoma. Further staging revealed splenomegaly. Intestinal angiocentric T/NK cell lymphoma represents a distinct etiology of diverticulum with perforation.

Prenatal sonographic diagnosis of meconium peritonitis: a case report.

A case of meconium peritonitis that was diagnosed ultrasonographically in the third trimester is presented. Fetal ascites, intra-abdominal calcification, left communicating hydrocele, and polyhydramnios were detected on antenatal ultrasonography. Specks of calcification were also demonstrated on abdominal radiography postnatally. Laparotomy confirmed the diagnosis of perforated terminal ileum with meconium peritonitis. The obstetric and neonatal implications of meconium peritonitis are discussed with literature review.
