#1 - Increased frequency of pneumonia in dogs with meningioma in ventral rhombencephalon
Abstract in English:
Intracranial tumors occurring in specific brain regions, such as the cerebellopontine angle, may be associated with cranial nerve dysfunction and dysphagia in humans and animals. Although dysphagia is a known risk factor for pneumonia, only postoperative pneumonia has been investigated in veterinary medicine. This study aimed to describe the clinical and pathological features of dogs with untreated intracranial meningiomas and concomitant pneumonia. Data from post-mortem examination registries from 2011 to 2021 were used (n=23). The frequency of pneumonia and other characteristics were compared between dogs with meningiomas in the ventral rhombencephalon region (VR group; n=13) and those with meningiomas in other intracranial sites (OIS group; n=10). The frequency of pneumonia was higher in the VR group than in the OIS group (n=5 vs. n=0; P=0.039). Plaque-like lesions were also more common in the VR group than in the OIS group (P=0.012). Dogs with concomitant pneumonia had cerebellopontine angle (n=3) and basilar meningiomas (n=2), mainly plaque-like lesions extending to or from other brain areas. In dogs with concomitant pneumonia, meningiomas had invasive (n=5) and compressive (n=3) growth behaviors and nerve roots involved in the swallowing process were frequently affected. Microscopically, these meningiomas were classified as atypical (n=4) and meningiomas (n=1). The reported clinical signs included anorexia (n=3), adipsia (n=1), and dysphagia (n=1). Our findings suggest untreated dogs with ventral rhombencephalon meningiomas may develop cranial nerve damage and aspiration pneumonia.
Abstract in Portuguese:
Tumores intracranianos que ocorrem em regiões específicas do cérebro, como o ângulo ponto-cerebelar, podem estar associados à disfunção de nervos cranianos e disfagia em humanos e animais. Embora a disfagia seja um conhecido fator de risco para pneumonia, apenas a pneumonia pós-operatória tem sido investigada na medicina veterinária. Este estudo teve como objetivo descrever as características clínicas e patológicas de cães com meningiomas intracranianos não tratados e pneumonia concomitante. Foram utilizados dados de registros de necropsias de 2011 a 2021. A frequência de pneumonia e outras características foram comparadas entre cães com meningiomas na região do rombencéfalo ventral (grupo VR; n=13) e aqueles com meningiomas em outros sítios intracranianos (grupo OIS; n=10). A frequência de pneumonia foi maior no grupo VR do que no grupo OIS (n=5 vs. n=0; P=0,039). Lesões tipo placa também foram mais comuns no grupo VR do que no grupo OIS (P=0,012). Cães com pneumonia concomitante apresentaram meningiomas no ângulo ponto-cerebelar (n=3) e região basilar (n=2), predominantemente lesões em forma de placa que se estendem de ou para outras áreas do cérebro. Em cães com pneumonia concomitante, os meningiomas apresentaram comportamentos de crescimento invasivo (n=5) e compressivo (n=3) e as raízes nervosas envolvidas no processo de deglutição foram frequentemente afetadas. Microscopicamente, esses meningiomas foram classificados como atípicos (n=4) e papilar (n=1). Os sinais clínicos relatados incluíram anorexia (n=3), adipsia (n=1) e disfagia (n=1). Nossos achados sugerem que cães com meningiomas no rombencéfalo ventral, não tratados, podem desenvolver lesão em nervos cranianos e pneumonia aspirativa.
#2 - Description of brachial plexus of sloth (Bradypus variegatus)
Abstract in English:
The species Bradypus variegatus is known as the common sloth, an endemic mammal from neotropical regions, which has been suffering from devastating anthropogenic activities. Our study aimed to describe the brachial plexus of B. variegates, regarding the origin and distribution of nerves, through the sampling of 10 adult females. Analyses were carried out at the Anatomy Section, “Departamento de Morfologia e Fisiologia Animal”, “Universidade Federal Rural de Pernambuco”, under license no. 034/2015 of the Ethics Committee on the Use of Animals. The results determined that the brachial plexus of the common sloth starts from the fifth cervical spine segment until the second thoracic segment. This area contains the long and suprascapular thoracic nerves, which originate immediately from the medullary segment 5 and 6, respectively, and from the pectoral, subscapular, axillary, radial, musculocutaneous, medial, forearm and ulnar medial cutaneous nerves, arising from a trunk comprised of cervical spine nerves (C) 7, C8, C9, and thoracic (T) 1 and T2. Regarding other wild and domestic animals, different suggestions were observed about the origin of the plexus in B. variegatus, however, the constituent nerves and their innervation areas did not demonstrate any discrepancies.
Abstract in Portuguese:
A espécie Bradypus variegatus é conhecida como preguiça-comum. Trata-se de um mamífero endêmico de regiões neotropicais que vem sofrendo com a ação antrópica devastadora. Esses Bradipodídeos possuem três dedos nos membros torácicos e pélvicos, são arborícolas consagrados e descem ao solo apenas para excretar e trocar de árvore. O estudo teve como objetivo descrever o plexo braquial de B. variegatus em relação à origem e distribuição dos nervos. Para tal, utilizou-se 10 fêmeas adultas. As análises foram realizadas no Pavilhão de Anatomia do Departamento de Morfologia e Fisiologia Animal da Universidade Federal Rural de Pernambuco, sob a licença nº 034/2015 do Comitê de Ética no Uso de Animais. Os cadáveres foram obtidos após morte natural, fixados em formaldeído a 20%, conservados em solução salina a 30% em tanques e dissecados para a visualização dos nervos destinados a inervar os membros e músculos torácicos. Uma vez feito, constatou-se que o plexo braquial da preguiça-comum se origina do quinto segmento espinal cervical, se estendendo até o segundo segmento torácico. Sendo formado pelos nervos torácico longo e supraescapular, de origem imediatamente do segmento medular 5 e 6, respectivamente, e pelos nervos peitorais, subescapulares, axilar, radial, musculocutâneo, mediano, cutâneo medial do antebraço e ulnar, decorrentes de um tronco formado a partir de nervos espinais cervicais (C) 7, C8, C9, e torácicos (T) 1 e T2. Em comparação a outros animais silvestres e domésticos foram observadas diferentes disposições em relação à origem do plexo de B. variegatus, todavia, os nervos constituintes e suas áreas de inervação não apresentaram discrepâncias.

The common marmoset (Callithrix jacchus) is a small primate that inhabits shrub forests of the Caatinga and the Atlantic Forest in Brazilian Northeast. This species of marmoset is very common and easy to adaptation in captivity, aspect that encourages illegal capture of these animals that are victims of mistreatments, causing injuries. The lack of knowledge in anatomy in marmosets and other wildlife hinders the safe application of clinical, surgical and therapeutic procedures. The brachial plexus has been described in some species of animals, but so far, there is no description for common marmoset (Callithrix jacchus). To study the brachial plexus of these animals were dissected ten corpses of common marmosets (Callithrix jacchus) adults, being five males and five females. In all animals, the brachial plexus was originated from spinal nerves C5, C6, C7, C8 and T1, with few variations in origin and the contributions of the nerves in both antimeres, forming three trunks: the cranial (C5 and C6), medium (C7) and caudal (C8 and T1).

O sagui-de-tufos-brancos (Callithrix jacchus) é um pequeno primata que habita florestas arbustivas da Caatinga e a Mata Atlântica do Nordeste brasileiro. Essa espécie de sagui é muito comum e de fácil adaptação ao cativeiro, aspecto que estimula a captura clandestina desses animais, os quais são vítimas de maus tratos que causam lesões. A falta de conhecimento da anatomia de saguis e outros animais silvestres dificulta a aplicação segura de procedimentos clínicos, cirúrgicos e terapêuticos. O plexo braquial tem sido descrito em algumas espécies animais, porém até o momento não existia descrição em saguis-de-tufos-brancos (Callithrix jacchus). Para estudar o plexo branquial desses animais foram dissecados dez cadáveres de saguis-de-tufos-brancos (Callithrix jacchus) adultos sendo cinco machos e cinco fêmeas. Em todos os animais o plexo braquial originou- se dos nervos espinhais C5, C6, C7, C8 e T1, com poucas variações na origem e nas contribuições dos nervos, em ambos os antímeros, formando três troncos: cranial (C5 e C6), médio (C7) e caudal (C8 e T1).

Callithrix jacchus and Callithrix penicillata are small primates used as anatomic model, not only for convenience in handling as ease in regard to breeding and reproductive rate. The aim of this study was to describe the components of the brachial plexus in Callithrix jacchus and C. penicillata. Three specimens about 8 years old and weighing 240g were fixed in 10% formaldehyde and subsequently dissected and photodocumented. The brachial plexus of Callithrix jacchus and C. penicillata originates from the spinal nerves C5 to T1 in continuation of the cranial, medium and flow trunk. The composition of the brachial plexus of these animals is similar to the one of other primates ands other mammals.

The anatomical comparative studies among the primates are important for the investigation of ethology, evolution, taxonomy, and comprehension of tools by hominoids. Especially the anatomical knowledge of Cebus contributes to conservation of the species, and to development of surgical procedures and clinical treatments of these animals, as they frequently are victims of automobile accidents. Recent anatomical studies came to a wrong conclusion regarding behavioral traits of Cebus, ascribed to few data available in previous literature. Therefore, to provide anatomical data and to support the other sciences related to anatomy, and to develop surgical and/or clinical procedures, we described the nerves of the legs of Cebus foccusing on their position and trajectory, as wll as innerved muscles, and compared these results with those of humans and other primates. Eight adult capuchin specimens were used for this study. The anatomical comparative study of the leg’s nerves of Cebus demonstrated that, in general, structural organization of the nerves is similar among the four primates analyzed here (Cebus, chimpanzees, baboons and humans), which might be attributed to the fact that the all four primates have similar body structures. However, nerve trajectory and muscles innervation in Cebus was more similar to baboons.

Os estudos anatômicos comparativos entre os primatas são importantes para pesquisas associadas com a etologia, evolução, taxonomia e compreensão dos usos de ferramentas pelos hominídeos. Especificamente, o conhecimento anatômico sobre Cebus contribui para sua própria conservação e para o desenvolvimento de procedimentos cirúrgicos e tratamentos clínicos destes animais, pois são frequentemente vítimas de acidentes automobilísticos. Recentemente, estudos sobre características comportamentais de Cebus indicaram conclusões erradas sobre sua anatomia, o que pode ser atribuído aos poucos dados disponíveis sobre a anatomia desses animais na literatura especializada. Portanto, para fornecer dados anatômicos e fornecer suporte para as outras ciências relacionadas com a anatomia e também desenvolver procedimentos cirúrgicos e/ou clínicos, foram descritos os nervos das pernas de Cebus com enfoque sobre a posição, a trajetória e os músculos inervados, e comparar esses resultados com os dos humanos modernos e outros primatas. Oito espécimes adultos de macacos-prego foram usados para este estudo. O estudo anatômico comparativo dos nervos da perna de Cebus demonstrou que, em geral, a organização estrutural dos nervos é semelhante entre os quatro primatas aqui analisados (Cebus, chimpanzés, babuínos e humanos modernos), o que pode ser atribuído ao fato de que os quatro primatas terem estruturas corporais semelhantes. No entanto, a trajetória dos nervos e a inervação dos músculos em Cebus o aproximam dos babuínos.
#6 - Comparative anatomy of the thigh nerves of Cebus libidinosus (Rylands et al., 2000, 31(3):261-266

Non-human primates have constituted an important group among animals subjected to various studies. Ethological, evolutionary and paleontological studies have revealed changes in anatomical structures linked to the evolution of primates, considered in studies on the comparative anatomy between Cebus libidinosus and other neotropical monkeys or those from the Old World, and the detailed knowledge on their anatomy may represent an important factor for their preservation and protection when the animals are brought to veterinary clinics after accidents or illnesses. In terms of veterinary importance, sometimes these animals arrive in the veterinary medical clinics after accidents, needing surgery or clinical treatment, but the little data available on anatomy has impaired the correct proceedings. The main justification for studies on C. libidinosus, is due to little information about the anatomy related to C. libidinosus in Brazilian and worldwide scientific literature. In this study, the distribution, enervation and path of the femoral and sciatic nerves of the pelvic limb (thigh) of C. libidinosus were studied and these results were compared with literature on the anatomy of humans, chimpanzees and baboons. In general, the enervation model of the four primates is identical, but in specific terms, the differences in enervations indicate evolution convergence closer to the branch of baboons in the evolutionary tree, and these data corroborate other comparative studies in relation to the same primates to vessels, muscles and nerves. In conclusion, the nerve organization in the thigh of C. libidinosus is identical to baboon, chimpanzee and homo, but more similar to baboon. The specific differences found indicate an ancient phylogenic origin to C. libidinosus and baboons (data corroborated by other studies).

Primatas não-humanos têm constituído um importante grupo entre os animais submetidos a vários estudos. Estudos etológicos, evolutivos e paleontológicos revelaram alterações das estruturas anatômicas ligada à evolução dos primatas, considerado em estudos sobre a anatomia comparativa entre Cebus libidinosus e outros primatas neotropicais ou provenientes do Velho Mundo, e as modalidades de conhecimento sobre sua anatomia pode representar um fator importante para a sua preservação e proteção quando os animais são levados às clínicas veterinárias após acidentes ou doenças. Em termos de importância veterinária, ás vezes esses animais chegam na clínica médica veterinária após acidentes, necessitando de cirurgia ou tratamento clínico, mas os poucos dados disponíveis sobre a anatomia tem dificultado o procedimento correto. A principal justificativa para os estudos sobre C. libidinosus é devido a pouca informação sobre sua anatomia na literatura científica no Brasil e no mundo. Neste trabalho, a distribuição, inervação e os trajetos dos nervos femoral e isquiático do membro pélvico (coxa) de C. libidinosus foram estudados e os resultados foram comparados com a literatura sobre a anatomia dos seres humanos, chimpanzés e babuínos. Em geral (Anatomia Macroscópica), o modelo de inervação dos quatro primatas é idêntico, mas em termos específicos, as diferenças nas inervações indicam uma convergência evolucionária em direção à árvore genealógica dos babuínos, dados corroborados por outros estudos comparativos em relação aos mesmos primatas para vasos, músculos e nervos. Em conclusão, a organização dos nervos na coxa de C. libidinosus é idêntico ao do babuíno, chimpanzé e homo, mas mais semelhante ao babuíno. As diferenças específicas encontradas indicam uma origem filogenética antiga para C. libidinosus e babuínos (dados corroborados por outros estudos).

Three outbreaks of poisoning by Prosopis juliflora pods are reported in the semiarid region of the state of Pernambuco, Northeastern Brazil, in cattle grazing in fields invaded by the plant or ingesting mesquite beans as a concentrate food. In two farms the disease occurred sporadically. In another, 112 (9.28%) cattle out of 1206 were affected, 84 (6.96%) died due to emaciation, and 28 (2.32%) gained weight after the pods had been withdrawn from the feed. Main clinical signs were progressive weight loss, atrophy of the masseter muscles, dropped jaw, tongue protrusion, difficulties in prehending food, tilting the head during mastigation or rumination, salivation, impaired swallowing, and decreased tone of the tongue. The hematology reveals hypoproteinemia and anemia. Gross lesions were emaciation and reduction in size of the masseter muscles, which appear thinner than normal and grayish due muscular atrophy. Degeneration of neurons of the trigeminal motor nuclei, Wallerian degeneration of the trigeminal nerve roots, and muscular atrophy of the masseter muscles with substitution by fibrous tissue were observed on histologic examination. For the prevention of the poisoning is necessary to limit the amount of mesquite beans in animal nutrition. It is also necessary to develop research to determine the economic and sustainability of the use of Prosopis juliflora for animal food, human food or other uses such as charcoal, wood and fuel wood.

Thirty diaphragms of sheep of Santa Inês breed were studied regarding their origin, division and arrangement of the right and left phrenic nerves (Fde), and the participation of other nerves in the innervation of the diaphragm. By fixing and dissecting pieces, it was found that phrenic nerves (F) frequently come from the ventral branches of the 5th (C5) and 6th (C6) cervical spinal nerves (Ec), at right (46.67%) and at left (43.33%). The F often form a lumbocostal trunk, sternal branches at right (40.00%) and lumbar, costal and esternal branches at left (36.68%). The lumbar branches of F innervate frequently at left (96.67%) the homolateral pillar of the diaphragma, and at right (50.00%) they give fillets to Vena cava caudalis. The costal branches of the F innervate at left (90.00%) and at right (76.66%) the dorsal and ventral regions of the pars costalis. The sternal branches of the F innervate at right (100.00%) and at left (83.33%) the pars sternalis and the ventral region of the pars costalis at the same side. The intercostal nerves (VII to XII pairs, 63.33%) contribute to innervate the diaphragm of Santa Inês sheep.

The purpose of this study is to demonstrate a new surgical approach for the selective denervation of the sensitive fibers of the acetabular periosteum, for the treatment of hip dysplasia in dogs, conducted in 189 joints.The surgical approach of the cranial and dorso-lateral regions of the acetabular joint in dogs, by moon-shaped incision of approximately 3cm in extension, starting from the greater trocanter of the femur, in direction of the ileum body. After dorsal opening of the middle gluteal muscle, the insertion of the deep gluteal muscle is inserted for the access to the mentioned regions. With the help of a curette, the periosteum of the cranial and dorso-lateral acetabular margin was removed until the bone cortex was exposed, in all patients. In all animals, the approach was possible, both in the cranial as well as in the caudal faces for the access and curettage of the acetabulum, with the technique described, with a skin incision of about 3.2cm. The curettage of the cranial portion of the acetabulum was, in all cases, realized without the visualization of the bone, but of easy achievement and without intercurrences of nervous or muscular injuries. In all the approaches, it was possible to visualize the articular capsule of the coxo-femoral joint, and in none of the animals, this structure was incised for a technique mistake. The surgical approach described in the present study is feasible for this kind of surgical procedure in dogs, promoting adequate access, with minimal invasion and with no complications of any nature.
