Estudo anatomomorfológico do Schistosomus reflexus em um bovino / Anatomomorphological study of Schistosomus reflexus in a cattle

O Schistosomus reflexus (SR) é uma anomalia congênita fatal de baixa incidência observada principalmente em ruminantes. O objetivo deste estudo foi relatar a ocorrência de SRem uma vaca com um quadro de distocia, multípara e de partos anteriores normais, atendida em uma propriedade localizada em Irati, região Centro-Sul do Paraná, Brasil. Durante a anamnese, foi relatado que o trabalho de parto ocorreu normalmente, com dilatação cervical e rompimento da bolsa alantoidiana e amniótica. Contudo, não ouve exteriorização do feto. Devido à inviabilidade da tração forçada observada no exame físico, optou-se pela cesariana. O feto extraído era disforme, apresentando dorsoflexão da coluna vertebral, órgãos abdominais expostos, anquilose de membros e face deformada, as quais são alterações anatômicas compatíveis com as características de Schistosomus reflexusdescritas na literatura. O caso apresentado contribui de forma relevante para o aprimoramento da compreensão e estudos sobre esse distúrbio, uma vez que sua ocorrência é rara.

Schistosomus reflexus (SR) is a fatal congenital anomaly of low incidence mainly observed in ruminants. This study aimed to report the occurrence of SR in a cow with dystocia, multiparous, and normal previous deliveries, treated in a property located in Irati, south-central region of Paraná, Brazil. During anamnesis, it was reported that labor occurred normally, with cervical dilation and disruption of the allantoic and amniotic stalk. However, there was no externalization of the fetus. Due to the infeasibility of the forced traction observed in the physical examination, a cesarean was performed. The extracted fetus was misshaped, presenting dorsiflexion of the spine, exposed abdominal organs, ankylosis of limbs, and deformed face, which are anatomical alterations compatible with the characteristics of Schistosomus reflexus described in the literature. The case reported contributes significantly to the improvement of understanding and studies on this disorder, since its occurrence is rare.

Schistosomus reflexus in dogs: case report

The Schistosomus reflexus (SR) etymologically refers to an abdominal and / or thoracic cleft with eventration of viscera. This pathology is diagnosed more frequently in ruminants such as cattle and sheep compared to few cases reported in dogs. According to reports, this is the fourth case of SR that is reported in canines. This condition is likely caused by various factors such as endocrine, alimentary, metabolic, hereditary and teratogenic in the first third of gestation, leading to disorders in embryonic development. In this report, a two-year-old canine Pinscher that presented clinical signs of birth was taken to the Veterinary hospital. Four puppies were born; three of them presented morphological malformations, being compatible with SR. It was observed abdominal cleft associated to abdominal and thoracic ventral midline defect, eventration with exposure of viscera (liver, intestines, and spleen), cleft palate, proptosis and microcephaly.

Schistosomus reflexus in a dog and a cat

Background: Schistosomus reflexus (SR) is a congenital anomaly, that the animal presents exposed abdominal and thoracic organs. The alterations includes limbs malformation, abnormal spinal column, liver and diaphragm hypoplasia, genitourinary and gastrointestinal changes, on this way, the fetus can not survive. The aim of this study was to report the first SR case in dog and cat in Brazil, and describe anatomical, pathological and radiographic changes. Case: The puppy had ventral midline defect in the abdominal and thoracic wall extending from the sternum to the pubis with viscera exposition, including the heart, lung, liver, stomach, intestine, spleen, kidneys, moreover right army was abnormal, however no spinal column was present. It was performed radiography to evaluate bone abnormalities, and was diagnosed agenesis of carpal, metacarpal and phalange bones. The kitten had ventral midline defect measuring 4 x 2 cm, in the abdominal wall and exposition of liver, stomach, intestine and spleen, as well as tibiotarsal joint arthrogryposis on both lags. It was performed fetus radiography and no spinal column change was diagnosed. Discussion: Schistosomus reflexus is a congenital abnormality common in ruminants. Although it was few reported in dogs and cats. The two cases in this study are the firsts reposts in Brazil in these especies. In our case, the dog had exposition of abdominal and thoracic organs and died one hour after born, similar to this, another author reported a case where the thoracic and abdominal evisceration and the puppy died ten minutes after born. However, in another case with abdominal evisceration only, the puppy survived for eight days. Probably it happened because respiratore function was not compromised. The kitten had abdominal opening only, in turn, other authors reported a case whose abdominal viscera exposition was by pelvic fissure, and another case, what presented thoracic and abdominal evisceration, like our dog case...

Monstros fetais como causa de distocia em vacas / Monsters fetal as cause of dystocia cows

O objetivo deste trabalho foi relatar os tipos de monstros fetais associados aos casos de distocias de origem fetal em vacas atendidas na rotina hospitalar no período de 11 anos. Para isso foram utilizadas informações das fichas de acompanhamento clinico de 397 vacas com distocias fetais, destas 27 ocorreram por anomalias fetais. Os monstros fetais simples (MFS) e os monstros fetais complexos (MFC) representaram 6,8% dos casos de distocia de ordem fetal. Observando 74% dos casos de MFS, com uma maior ocorrência de Schistosomos reflexus 45%, seguida de contraturas e flexões 30%, ascite 10% e Perossomus elumbis 10%, além de hidrocefalia 5%. Nos 26% dos casos de MFC, 43% foram Thoracogastropagus, 29% Dicephalus, 14% Diprosopus e 14% Duplicitas posterior. A ocorrência de monstros fetais está presente na bovinocultura, representando fator de risco para o desencadeamento de partos distócicos e acarretando em perdas econômicas para esta atividade com os procedimentos e a alta mortalidade dos animais. Nas situações de manobra obstétrica, os veterinários devem levar em consideração a possibilidade da presença de alterações congênita fetal para se tomar a medida mais apropriada para o caso e com isso minimizar o sofrimento e a mortalidade tanto da vaca quanto do feto.(AU)

The aim of this study was to report the types of fetal monsters associated with cases of dystocia of fetal origin in cows treated at hospital routine in the period of 11 years. For this we used information from clinical monitoring reports of 397 cows with dystocia fetal, 27 of these were for fetal anomalies. The simple fetal monsters (MFS) and complex fetal monsters (MFC) represented 6,8% of the cases of fetal dystocia. Observing 74% of cases of MFS with a higher incidence of Schistosomus reflexus 45%, then bending and contractures 30%, ascites 10%, Perossomus elumbis 10% and hydrocephalus 5%. In 26% of cases of MFC, 43% were Thoracogastropagus, 29% Dicephalus, 14% Diprosopus and 14% Duplicitas posterior. The occurrence of fetal monsters are present in cattle, representing a risk factor for the onset of dystocia and resulting in economic losses for this activity with the procedures and the high mortality of animals. During obstetrical maneuvers, veterinarians should consider the possibility of the presence of fetal congenital changes to take the most appropriate measure for the case and thereby minimize the suffering and mortality of both the cow and fetus.(AU)

Estudo anatomorfológico, radiográfico e tomográfico de Schistosomus reflexus em ovino da raça Dorper: relato de caso / Anatomorphological, radiographic and tomographic studies of Schistosomus reflexus in Dorper breed sheep: case report

O Schistosomus reflexus (SR) é uma anomalia congênita fatal e rara, primariamente observada em ruminantes, a qual apresenta feto com dorsoflexão da coluna vertebral, exposição das vísceras abdominais e torácicas e escoliose. Foi realizada uma cesariana de ovelha da raça Dorper, em propriedade da região de Botucatu-SP. Pelas características gerais e achados de necropsia, tratava-se de um caso de SR. A radiografia revelou acentuado desvio ventrodorsal do segmento da coluna vertebral toracolombar e deformidades das costelas. Na tomografia computadorizada, observou-se presença da integridade dos ossos e órgãos, exceto ausência de uma vértebra lombar. Não havia dados na literatura de diagnóstico por imagem de SR em ovinos, portanto procedeu-se, de forma inédita, a exames radiográfico e tomográfico do feto.(AU)

Schistosomus reflexus (SR) is a rare and fatal congenital anomaly, primarily observed in ruminants, presenting fetus with dorsiflexion of the vertebral column, exposure of thoracic and visceral organs, and scoliosis. A caesarian was performed on a Dorper sheep on a farm in Botucatu-SP and according to the general characteristics and findings observed in the necropsy of the fetus it was an SR case. The radiography indicated a marked ventro-dorsal deviation of the thoracolumbar column segment and deformity of the ribs. On the computed tomography the integrity of the bones and organs were detected, except for the absence of a lumbar vertebra. No data were available in the literature for SR diagnosis in sheep by image, so radiographic and tomographic exams of the fetus were done.(AU)

Defeitos congênitos em bovinos da Região Central do Rio Grande do Sul / Congenital defects in cattle from central Rio Grande do Sul, Brazil

Foram revisados casos de defeitos congênitos (DCs) diagnosticados em bovinos no Laboratório de Patologia da Universidade Federal de Santa Maria em 1964-2010. Durante o período estudado, foram examinados materiais provenientes da necropsia de 7.132 bovinos e foram encontrados 31 bezerros (0,4 por cento) com DCs, os quais foram classificados em 34 tipos e alocados nos sistemas orgânicos primariamente afetados. Os DCs ocorriam isoladamente (19 [61,3 por cento]) ou afetavam múltiplos sítios anatômicos (15 [28,7 por cento]) com frequência semelhante em ambos os sexos. Como vários terneiros mostraram múltiplos DCs, um total de 53 DCs foi computado. Dos 53 DCs diagnosticados, 15 (28,3 por cento) afetavam o sistema nervoso central (craniósquise [4], abiotrofia cerebelar [2], degeneração esponjosa [2], hidrocefalia [2], meningocele [2], espinha bífida [1], hipoplasia cerebelar [1] e hipomielinogênese [1]); nove (17,0 por cento) afetavam o sistema urogenital (agenesia testicular [1], agenesia vaginal [1], hipoplasia peniana [1], formação de cloaca [1], freemartinismo [1], hamartoma vascular de ovário [1], hipoplasia renal [1], cistos renais [1] e úraco persistente [1]); oito DCs (15,1 por cento) eram primários do sistema musculoesquelético (artrogripose [4], escoliose [1], plagiocefalia, [1] schistosomus reflexus [1] e diprosopia [1]); e outros oito (15,1 por cento) foram alocados no sistema digestivo (palatosquise [3], atresia anal [1], atresia anorretal [1], atresia - anocolônica [1], fístula reto-vaginal [1] e fístula reto-uretral [1]); em cinco ocasiões (9,4 por cento) o DC afetava o sistema cardiovascular (persistência do ducto arterioso [2], persistência do forame oval [2] e defeito do septo ventricular [1]); quatro (7,5 por cento) afetavam o sistema linfático e consistiam de hipoplasia ou aplasia de vasos linfáticos e linfonodos associadas a linfedema. Dois casos (3,4 por cento), de hipotricose foram observados afetando o integumento; um caso (1,9 por cento) de estenose traqueal foi encontrado no sistema respiratório e um caso (1,9 por cento) de bócio envolvia o sistema endócrino. Os resultados indicam que a maioria dos DCs em bovinos na Região Central do Rio Grande do sul é esporádica. No entanto, seu estudo continuado é importante para o estabelecimento de sua etiologia e controle.(AU)

Cases of congenital defects (CDs) in cattle diagnosed at the Laboratory of Veterinary Pathology of the Federal University of Santa Maria from 1964 to 2010 were reviewed. During the studied period tissues collected from the necropsy of 7,132 cattle were examined and 31 calves (0.4 percent) with CDs were found. These CDs were classified into 34 different types and ascribed to the body system primarily affected. CDs were solitary (19 [61.3 percent]) or multiple (12 [38.7 percent]) and found with similar frequency in calves of both sexes. As several calves displayed multiple defects, a total of 53 CDs were computed. Out of the 53types of CDs diagnosed 15 (28.3 percent) affected the central nervous system (cranioschisis [4], cerebellar abiotrophy [2], spongy degeneration [2], hydrocephalus [2], meningocele [2], spina bifida [1], cerebellar hypoplasia [1], and hypomyelinogenesis [1]); nine (17.0 percent) affected the urogenital system (testicular agenesis [1], vaginal agenesia [1], penile hypoplasia [1], cloacal formation [1], freemartinism [1], ovarian vascular hamartoma [1], renal hypoplasia [1], renal cysts [1], and persistent urachus [1]); eight CDs (15,1 percent) were primary to the musculoskeletal system (arthrogryposis [4], scoliosis [1], plagiocephaly [1] schistosomus reflexus [1], and diprosopus [1]) and another eight (15,1 percent) were in the digestive system (palatoschisis [3], anal atresia [1], anorectal atresia [1], ano-colonic atresia [1], recto-vaginal fistula [1], and recto-urethral fistula [1]); in five instances (9.4 percent) the CD affected the cardiovascular system (persistent ductus arteriosus [2], persistence of foramen ovale [2], and ventricular septal defect [1]); four (7.5 percent) affected the lymphatic system and consisted of inherited hypoplasia or aplasia of lymphatic vessels and lymph nodes associated with lymphedema. Two cases (3.0 percent), of hypotrichosis were observed affecting the integument; one case (1.9 percent) of tracheal stenosis was found in the respiratory system and one case of goiter (1.9 percent) involved the endocrine system. The results of this survey inidicate that the majority o CDs in cattle in the central Rio Grande do Sul are sporadic; nevertheless their continued study is important for determining the etiology and control.(AU)

Uma forma rara de ocorrência do Schistosomus reflexus em bovinos / A rare form of occurrence of Schistosomus reflexus in bovine / Una Forma Rara De Ocurrencia De Schistosomus Reflexus En Vacuno Relato Del Caso

O Schistosomus reflexus (SR) é uma anomalia congênita fatal e rara, primariamente observada em ruminantes, gestando um feto com dobradura da coluna vertebral, exposição das vísceras abdominais e torácicas, anquilose dos membros, hipoplasia hepática e diafragmática, escoliose e anormalidade do sistema digestório e genitourinário. Foi trazido aoHospital Veterinário da FMVZ - UNESP Botucatu/ SP, uma aberração congênita disforme removida por tração forçada em um parto distócico de vaca mestiça, pertencente a um criador do Município de Lençóis Paulista/ SP. Pelas características gerais e achados de necropsia foi possível concluir tratar-se de um caso raro de SR, não havendo na literatura relato de caso similar desta má formação integralmente revestida pela epiderme e derme.(AU)
