Use of F18 bioglass putty for induced membrane technique in segmental bone defect of the radius in rabbits.

PURPOSE: To evaluate the inductive capacity of F18 bioglass putty on the induced membrane technique in a segmental bone defect of the rabbit's radius. METHODS: Ten female Norfolk at 24 months of age were used. The animals were randomly separated based on postoperative time points: five rabbits at 21 and four at 42 days. A 1-cm segmental bone defect was created in both radii. The bone defects were filled with an F18 bioglass putty. RESULTS: Immediate postoperative radiographic examination revealed the biomaterial occupying the segmental bone defect as a well-defined radiopaque structure with a density close to bone tissue. At 21 and 42 days after surgery, a reduction in radiopacity and volume of the biomaterial was observed, with particle dispersion in the bone defect region. Histologically, the induced membrane was verified in all animals, predominantly composed of fibrocollagenous tissue. In addition, chondroid and osteoid matrices undergoing regeneration, a densely vascularized tissue, and a foreign body type reaction composed of macrophages and multinucleated giant cells were seen. CONCLUSIONS: the F18 bioglass putty caused a foreign body-type inflammatory response with the development of an induced membrane without expansion capacity to perform the second stage of the Masquelet technique.

Episódios de cuidado cotidiano: diálogos sobre raça, maternagem e rede de apoio / Episodes of daily care: dialogues on race, mothering and support network

Este estudo se dedica a pensar os efeitos do racismo e da racialidade enquanto elementos estruturantes do mundo em que vivemos e da saúde sexual e reprodutiva de mulheres negras, seus projetos de vida e exercício de parentalidade. Por meio de uma perspectiva sobre a impossibilidade da justiça, considerando a necessidade de destruição do Mundo como o conhecemos, e iluminando (com luz negra) a perversidade que não é uma falha mas é a característica mesma do projeto racial que está na base das formações sociais modernas, este trabalho dá centralidade à potência dos emaranhados sociais e da coletividade na produção de estratégias de continuidade da vida, dialogando com as noções de rede e sobrevivência coletiva. Seu objetivo é entender os sentidos e práticas das redes de apoio de mulheres racializadas durante o ciclo gravídico puerperal e no exercício de cuidado à prole em contexto de vulnerabilização. Este é um estudo qualitativo de caráter analítico- exploratório cujas fontes de dados foram produções da literatura científica, registros em diário de campo e discursos das mulheres participantes. Os instrumentos da pesquisa foram uma roda de conversa e duas entrevistas individuais de mulheres mães pretas e periféricas; e a análise elaborada a partir da metodologia episódica proposta por Grada Kilomba. Esta autora encontrou nas narrativas de histórias pessoais de mulheres negras, episódios de suas vidas, a possibilidade de reconstruir e recuperar percepções e definições próprias dos sujeitos que as experenciaram e as têm como própria realidade. Os resultados construídos revelam que os sentidos e práticas das redes de apoio das mulheres-mães negras periféricas envolvidas nesse estudo são múltiplos e ambíguos. Ao mesmo tempo em que possibilitam a emancipação da mulher ao papel da mãe que se dedica integralmente aos filhos em detrimento de seus desejos individuais descolados da maternagem, são também moduladores de sua maternagem e reprodutores da opressão imposta por esse modelo socialmente consolidado. O cenário é complexo, há disputas de gênero, poder institucionalizado, mecanismo de manutenção da visão do outro racial como identidade e referência, jogos de poder e conflito geracional, interesses próprios, alianças consanguíneas, relações por aliança, abandono, vida, vitórias, acolhimento, esperança, acordos, negociações, uma miríade de elementos que sustentam a existência destes sujeitos. Suas maternagens são especialmente atravessadas por eventos críticos, mortes materiais e simbólicas, que tornam seu sofrimento cotidiano e determinam que ressignifiquem sua existência diariamente, à medida em que compartilham o cuidado de seus filhos com seus pares.

This study is dedicated to thinking about the effects of racism and raciality as structuring elements of the world we live in as well as of black women's sexual and reproductive health, their life projects and parenting. Through a perspective on the impossibility of justice, considering the need to destroy the world as we know it, and by shedding (black) light on the perversity that is not a failure but the very characteristic of the racial project that underpins modern social formations, this work focuses on the power of social entanglements and collectivity in the production of strategies for the continuity of life, engaging with the notions of networks and collective survival. It aims to understand the meanings and practices of racialized women's support networks during the pregnancy-puerperium cycle and when caring for their offspring in a context of vulnerability. This is a qualitative study of an analytical-exploratory type and its data sources were scientific literature, field diary entries and the speeches of the participating women. The research instruments were a conversation circle and two individual interviews with black women who are mothers from a peripheral region, and the analysis was based on the episodic methodology proposed by Grada Kilomba. This author found in the narratives of black women's personal stories, episodes from their lives, the possibility of reconstructing and retrieving the perceptions and definitions of the subjects who experienced them and have them as their own reality. The results show that the meanings and practices of support networks of the black women who are mothers in the periphery and were involved in this study are multiple and ambiguous. At the same time as they make it possible for women to emancipate themselves from the role of mothers who dedicate themselves entirely to their children, in detriment to their individual desires detached from mothering, they are also modulators of their mothering and reproducers of the oppression imposed by this socially consolidated model. The scenario is complex, there are gender disputes, institutionalized power, a mechanism for maintaining the view of the racial other as an identity and reference, power games and generational conflict, self-interest, consanguineous alliances, alliance relations, abandonment, life, victories, acceptance, hope, agreements, negotiations, a myriad of elements that sustain the existence of these subjects. Their mothering is especially crossed by critical events, material and symbolic deaths, which make their suffering a daily occurrence and determine that they resignify their existence on a regular basis, as they share the care of their children with their peers.

Mortalidade materna de mulheres negras em município da região metropolitana de São Paulo: iniquidades, lacunas e possibilidades de intervenção / Maternal mortality of black women in a city fo São Paulo metropolitan region: inequalities, gaps and possibilities of intervention

O estudo discute elementos relacionados à atenção básica e mortalidade materna entre mulheres negras, passíveis de intervenção em saúde coletiva pelos representantes públicos, gestores e profissionais de saúde. A abordagem quanti-qualitativa, de cunho descritivo, realizada em 2019, avalia as (des)informações sobre variáveis da assistência pré-natal a partir de dados obtidos de relatórios de investigação de óbitos maternos ocorridos entre 2008 e 2018 no município de Franco da Rocha-SP. Foram analisados 13 relatórios; os dados produzidos pela pesquisa documental foram organizados por modalidade temática e interpretados à luz da literatura que versa sobre direitos sexuais e reprodutivos. A pesquisa reafirma que as condições biopsicossociais e de cuidado em saúde sexual e reprodutiva vivenciadas por mulheres negras no município em questão são desfavoráveis, contribuindo para desfechos fatais, mas aponta-se como estratégia de mudança a promoção da completude dos dados e informações sobre mortalidade materna. Pondera-se ser necessário a retomada de diálogos e de ações sobre a qualificação das práticas em saúde, assim como sobre o reconhecimento e superação do racismo estrutural, das interseccionalidades que influem na atenção ao pré-natal, parto e puerpério de mulheres negras.

A perspectiva de profissionais de saúde sobre os partos de natimortos / La perspectiva de los profesionales de salud sobre partos de nacidos muertos / The perspective of healthcare professionals on birth of stillborn

Resumo Profissionais que atuam em hospitais/maternidades enfrentam muitos desafios no atendimento a mulheres que estão vivenciando óbitos fetais, isso porque o habitual nesses locais é lidar com nascimento e vida. Nesse contexto, o objetivo deste estudo foi compreender a perspectiva de profissionais de saúde sobre o parto e o pós-parto de mulheres com diagnóstico de óbito fetal. Trata-se de uma pesquisa qualitativa orientada pela perspectiva construcionista; foram realizadas entrevistas semidirigidas com profissionais que atuam em um hospital/maternidade do estado de São Paulo. A análise discursiva indicou que as/os profissionais de saúde se identificam com o luto das mulheres e das famílias, mas não conseguem se aproximar delas e oferecer intervenções terapêuticas para além da medicalização. Desse modo, é fundamental investir na formação profissional para lidar com a morte, nos cursos de graduação em saúde e nos de educação continuada, nas maternidades e casas de parto.

Resumen Los profesionales que trabajan en hospitales / maternidades enfrentan muchos desafíos en el cuidado de mujeres que están sufriendo muerte fetal, porque lo que se acostumbra en estos lugares es lidiar con el nacimiento y la vida. En este contexto, el objetivo de este estudio fue comprender la perspectiva de los profesionales de la salud sobre el parto y el puerperio de las mujeres diagnosticadas de muerte fetal. Es una investigación cualitativa guiada por la perspectiva construccionista, se realizaron entrevistas semiestructuradas a profesionales que laboran en un hospital / maternidad del estado de São Paulo. El análisis discursivo indicó que los profesionales de la salud se identifican con el duelo de las mujeres y las familias, pero son incapaces de acercarse a ellas y ofrecer intervenciones terapéuticas más allá de la medicalización. Por ello, es fundamental invertir en formación profesional para afrontar la muerte, en cursos de pregrado en salud y en educación continua, en maternidades y centros de nacimientos.

Abstract Professionals working in maternity hospitals face many challenges in the care of women who are experiencing fetal deaths, because the usual in these places is to deal with birth and life. In this context, the aim of this study was to understand the perspective of health professionals about the labor and postpartum of the women diagnosed with fetal death. This is a qualitative research guided by the constructionist perspective; semi-directed interviews were conducted with professionals working in a maternity hospital in the state of São Paulo. The discursive analysis indicated that health professionals understand the mourning of the women and families, but cannot approach them and offer therapeutic interventions beyond medicalization. This way, it is essential to invest in training actions to deal with death, in undergraduate health courses and in those of continuing education in maternity hospitals and birth centers.

Acute effects of whole-body vibration on dopplerfluxometry of the common carotid artery parameters among adult and elderly non-athletes healthy dogs

Background: Whole-Body Vibration (WBV) is an oscillatory mechanical stimulus spreading throughout the body and considered a type of physical exercise because of the activation of the cardiovascular, musculoskeletal, and neuroendocrine systems. It is a physical exercise modality since it promotes cardiovascular resistance, increase in muscular strength and neurosensitivity, and motor coordination improvement. For use of WBV as an exercise modality for dogs, it is necessary to evaluate the Dopplerfluxometry parameters of the common carotid artery in healthy dogs in order to perform a safe protocol without inducing any cerebral alteration. This study aimed to evaluate the acute effects of WBV on systolic peak velocity (SPV), resistivity (RI), and pulsatility index (PI) of the both common carotid artery among adults and elderly non-athletes healthy dog. Materials, Methods & Results: Fourteen clinically healthy, neutered crossbreed male dogs, non-athlete were divided into two groups of seven dogs, according to the age group: Group 1 (G1)- Adult dogs: age between 12 and 84 months; Group 2 (G2)- Elderly dogs: aged over 84 months. All dogs were submitted to sessions of WBV using the protocol of 30 Hz for 5 min, followed by an increase to 50 Hz for 5 more min and ending with 5 min at 30 Hz, without rest between the variation of the vibration frequency. The systolic peak velocity (SPV), resistivity (RI), and pulsatility index (PI) of the common carotid artery were assessed in two time-points: 5 min before the WBV sessions (5PRE) and 1 min after the WBV (1POS). No significant variations in the SPS, RI, and PI of both common carotid artery of the G1 and G2 were identified. The anatomic reference for the left and right common carotid artery was the right and left extern jugulars veins, which were...

Effects of whole-body vibration in hematobiochemical and hemogasometric parameters in adult and elderly healthy dogs

Background: Whole-Body Vibration (WBV) consists of mechanical vibration stimuli produced that propagate throughout the body by increasing the gravitational load. The WBV can increase muscle mass in dogs with muscular atrophy. As Whole-body vibration (WBV) can be used as exercise modality with no impact on the joints, the present study aimed to evaluate the effects of single session of WBV in hematobiochemical and hemogasometric parameters in adult and elderly healthy dogs. Materials, Methods & Results: Fourteen clinically healthy, neutered crossbreed male dogs, non-athlete were selected. The dogs were divided into two groups of seven dogs, according to the age group: Group I - adult dogs (GI): age between 12.0 and 84.0 months old; Group II - elderly dogs (GII): age above 84.0 months old. All dogs were submitted to a single session WBV by using a vibrating platform that delivered a vortex wave circulation as mechanical vibration. The WBV protocol used was 30 Hz frequency (3.10 mm peak displacement; 11.16 m/s2 peak acceleration; 0.29 m/s velocity), then 50 Hz (3.98 mm peak displacement; 39.75 m/s2 peak acceleration; 0.62 m/s velocity), and lastly 30 Hz (3.10 mm peak displacement; 11.16 m/s2 peak acceleration; 0.29 m/s velocity) for 5-min between de frequencies. The hematobiochemical and hemagasometric parameters were evaluated at 1-min before the WBV session (1PRE), 1-min after the WBV session (1POST), 120-min (120POST) and 24 h after the WBV session (24hPOST). The dogs accepted the vibration stimulus quite well, however, elderly dogs weighing above 30 kg were more likely to sit down with increased frequency from 30 to 50 Hz. No variations of food and water intakes and gastrointestinal changes were observed after the WBV session. Hemoglobin values showed significant decrease (P = 0.0312) between 1PRE and 1POST in elderly dogs. A significant decrease (P = 0.0453) was observed in alanine aminotransferase values between 120POST...

Topical ozone therapy in the treatment of pharmacodermia in a dog (Canis lupus familiaris)

Background: Pharmacodermia is a drug reaction that manifests itself on the skin and mucous membranes. The main drugsthat cause pharmacodermia are β-lactam antibiotics. It has a rare occurrence in dogs and may present different clinical signs.Ozone therapy is used to treat various conditions, such as infections and inflammatory diseases. This therapy acts throughoxidative stress generating a positive inflammatory response to the body and stimulating the formation of granulation tissue andangiogenesis. Since pharmacodermia is rare in dogs and reports of ozonized sunflower oil and ozone for treat pharmacodermiais are rare in the literature, this paper aimed to report the use of ozonized sunflower oil in the treatment of pharmacodermiain a young female Rottweiler dog assisted and treated at a private veterinary clinic in Garanhuns, Pernambuco, Brazil.Case: A 2-year-old Rottweiler female, weighting 53.3 kg was attended at a private veterinary clinic in Garanhuns (Pernambuco- PE) with a history of dystocia. The dog was submitted to ovary-hysterectomy under general anesthesia. After anesthesiarecovery was prescribed omeprazol (1 mg/kg, orally (P.O) SID for 10 days), cephalexin (20 mg/kg, P.O. BID for 10 days),tramadol hydrochloride (4 mg/kg, P.O. BID for seven days), carprofen (4.4 mg/kg, P.O. SID for three days), and the use ofElizabethan collar. Furthermore, for topical treatment was described chlorhexidine digluconate (0.2%) and ointment of allantoin and zinc oxide, SID, for 10 days. Seven days after the surgical procedure, the owners dog reported by a telephone callthe appearance of wounds in the dorsal region of the dog.

Dopplerfluxometria da artéria femoral de cães adultos hígidos (Canis lupus familiaris) / Femoral artery Dopplerfluxometry of adult healthy dogs (Canis lupus familiaris)

Background: In Veterinary Medicine, there are several methods for early and accurate assessment of blood flow dynamics. The Dopplerfluxometry can access the peak systolic velocity, mean velocity and end diastolic velocity, including Resistive Index and Pulsatility Index. Normal values of Dopplerfluxometry in healthy dogs allow the identification of vascular abnormalities and authors’ knowledge there are no reference regarding the values of Dopplerfluxometry of the femoral artery in healthy dogs. The aim of the study was to assess the femoral Dopplerfluxometry of adult healthy dogs by Resistive Index, Pulsatility Index, systolic and diastolic velocities, and femoral artery diameter.Materials, Methods & Results: Eighteen healthy intact beagle dogs, male and female, aging from 2 to 4 years old (mean ± SD: mean 3 ± 0.8 years), weighing from 10.1-17.9 kg [22.3-39.5 lb] [mean ± SD: 14.3 ± 2.7 kg (31.5 ± 5.96 lb)] were used. The dogs underwent to physical examination, complete blood cell count, serum biochemistry examination urinalysis, and radiographs examination, muscular and cardiac evaluation. Females had to be in anestrous. All dogs were submitted to right femoral artery Dopplerfluxometry. The dogs were positioned in dorsal recumbency by one person without any chemical restraint. A high definition ultrasound device equipped with a 3 - 13 MHz multi-frequency linear transducer was used. The right femoral artery was identified with the transducer positioned transversely on the right triangle femoral area. Peak systolic velocity, end-diastolic velocity was measured. The Resistivity Index and Pulsatility Index were calculated automatically by the ultrasound machine software. Three measurements were obtained with the Doppler spectrum. The values of peak systolic velocity, end-diastolic velocity, Resistivity Index, Pulsatility Index and femoral artery diameter were expressed as Mean ± Standard Deviation (SD).[...]

Ovarian torsion in a primipara female dog in Brazil

Background: Ovarian torsion is a condition which the ovary and the ovarian pedicle twist around the ovary suspensory ligament. No report regarding this condition was reported. The aim of the report was to describe a case of unilateral ovarian torsion in a 2-year-old primipara Golden Retriever dog.Case: A 2-year-old female primipara Golden Retriever dog weighting was referred to the Veterinary Hospital, for purulent vaginal discharge evaluation. The dog was presenting anorexia, weight loss, and intermittent diarrhea and vomiting. A cesarean section was performed nine months before her presentation and the oestrus cycle was recorded six months after the cesarean section. Discomfort was observed during the palpation of the abdomen and purulent vaginal was observed. Vaginal swab was performed and followed by cytological examination. The ultrasonographic examination was consistent with pyometra. The ovariohysterectomy was performed and were observed torsion of the left ovary. The histopathological examination of the left ovary and uterus were consistent with ovary necrosis and pyometra. Ten days after surgery the vaginal discharge had resolved and the sutures were removed. Six months postoperatively the dog revealed no further abnormalities. Grossly, the left ovary had firm consistency, dark red surface and 8 cm diameter. The histopathology examination findings were consistent with a diagnosis of diffuse necrosis of left ovary due to ovarian torsion, and uterine suppurative inflammatory process - pyometra.Discussion: Ovarian torsion is uncommon in small animals, but can be observed high incidence in pregnant female dogs than in non-pregnant ones. The 360º an asynchronous ovarian torsion described in the present case is also an unusual condition in primipara female dogs due to the smaller stretching of the ovary suspensory ligament. The ovarian torsion is considerate an emergency condition due to acute abdominal pain.[...]

Femoral diaphyseal fractures fixation technique using an adjustable nylon tie in dog (Canis lupus familiaris) and cat (Felis catus domesticus)

Background: Adjustable nylon ties polyamide 6.6 is devices produced from the same material of surgical nylon wire and have been used in different surgical procedures in small animals and in human patient. Reports regarding the use of these devices as secondary fixation technique of femoral diaphyseal fractures in animals are rare in the literature. The aim of the present report case was to describe the use of adjustable nylon tie polyamide 6.6 as secondary fixation technique in a 3-year-old dog and 4-month-old cat, diagnosed with femoral diaphyseal fractures.Cases: Case 1. A 3-year-old female dog was presented with reluctance to support the left hind limb, with 5 days’ duration. Pain and edema on the left femoral diaphyseal region was identified. The limb was submitted to radiographic exam and revealed a closed, complete and comminuted fracture of the diaphysis of the femur, and was decided to perform a surgical stabilization by open reduction through primary fixation with intramedullary pin, and secondary fixation of bone fragments with adjustable nylon ties polyamide 6.6, as a substitute of steel cerclage wire. The bone fragments were alignment and fixated with five polyamide nylon ties. The excess was removed with a scalpel blade along the lock. Seven days after surgery the skin sutures were removed and were observed reluctance to support the left hind limb. Physiotherapy sessions were prescribed. Forty days after the surgery was performed a radiographic exam of the left hind limb which revealed alignment of the bone axis. Six months after the surgery, the owner reported that the dog supported the left hind limb. Case 2. A 4-month-old female cat was presented with history of trauma, with 24 h’s duration, and reluctance in supporting the left hind limb. On physical examination there was identified pain on the left femoral diaphyseal region.[...]

Pododermite em cisne negro (Cygnus atratus) em Moçambique / Bumblefoot in free-living black swan (Cygnus atratus) in Mozambique

Background: Black Swan (Cygnus atratus Linnaeus 1766) is an aquatic bird native to Australia and non-migratory birds. Bumblefoot is a chronic, progressive, degenerative and granulomatous disease that affects the plantar region and causes inflammation and degenerative changes in plantar tissues. Given that bumblefoot incidence in free-living wild birds is low and that the literature lacks publications about bumblefoot in free-living Black Swans, the aim of the current study is to describe the first bumblefoot case reported in a free-living Black Swan (Cygnus atratus) in Mozambique who was subjected to surgical procedure.Case: An adult intact Black Swan (Cygnus atratus) weighing 7.2 kg was presented to Veterinary Hospital of the Veterinary Medicine School, Mozambique with reluctance to support the left hind limb. Water intake was not unsettled and urine and feces were normal. A brown mass with 3 cm diameter approximately was identified in the footpad of the left hind limb; there were local bleeding and ulcers and pain. Footpad radiographic images of the left hind limb showed no abnormalities in the bone tissue. An incisional biopsy was performed with patient under sedation. The cytopathological examination was suggestive of bumblefoot. An excisional biopsy was performed with patient under anesthesia. The mass was excised with surgical margin of 1 cm and the local was subjected to debridement. The sample was sent to histopathological examination. The histopathological examination confirmed a chronic Bumblefoot Type 2. The patient started to support the left hind limb three days after surgery and twenty days after surgery, the footpad sutures were removed. Fifty days after the surgical procedure the patient was released in the site it was rescued.[...]

A 3-year-old female dog was presented with reluctance to support the left hind limb, with 5 days duration. Pain and edema on the left femoral diaphyseal region was identified. The limb was submitted to radiographic exam and revealed a closed, complete and comminuted fracture of the diaphysis of the femur, and was decided to perform a surgical stabilization by open reduction through primary fixation with intramedullary pin, and secondary fixation of bone fragments with adjustable nylon ties polyamide 6.6, as a substitute of steel cerclage wire. The bone fragments were alignment and fixated with five polyamide nylon ties. The excess was removed with a scalpel blade along the lock. Seven days after surgery the skin sutures were removed and were observed reluctance to support the left hind limb. Physiotherapy sessions were prescribed. Forty days after the surgery was performed a radiographic exam of the left hind limb which revealed alignment of the bone axis. Six months after the surgery, the owner reported that the dog supported the left hind limb. Case 2. A 4-month-old female cat was presented with history of trauma, with 24 hs duration, and reluctance in supporting the left hind limb. On physical examination there was identified pain on the left femoral diaphyseal region.[...](AU)

Ovarian torsion in a primipara female dog in Brazil

Background: Ovarian torsion is a condition which the ovary and the ovarian pedicle twist around the ovary suspensory ligament. No report regarding this condition was reported. The aim of the report was to describe a case of unilateral ovarian torsion in a 2-year-old primipara Golden Retriever dog.Case: A 2-year-old female primipara Golden Retriever dog weighting was referred to the Veterinary Hospital, for purulent vaginal discharge evaluation. The dog was presenting anorexia, weight loss, and intermittent diarrhea and vomiting. A cesarean section was performed nine months before her presentation and the oestrus cycle was recorded six months after the cesarean section. Discomfort was observed during the palpation of the abdomen and purulent vaginal was observed. Vaginal swab was performed and followed by cytological examination. The ultrasonographic examination was consistent with pyometra. The ovariohysterectomy was performed and were observed torsion of the left ovary. The histopathological examination of the left ovary and uterus were consistent with ovary necrosis and pyometra. Ten days after surgery the vaginal discharge had resolved and the sutures were removed. Six months postoperatively the dog revealed no further abnormalities. Grossly, the left ovary had firm consistency, dark red surface and 8 cm diameter. The histopathology examination findings were consistent with a diagnosis of diffuse necrosis of left ovary due to ovarian torsion, and uterine suppurative inflammatory process - pyometra.Discussion: Ovarian torsion is uncommon in small animals, but can be observed high incidence in pregnant female dogs than in non-pregnant ones. The 360º an asynchronous ovarian torsion described in the present case is also an unusual condition in primipara female dogs due to the smaller stretching of the ovary suspensory ligament. The ovarian torsion is considerate an emergency condition due to acute abdominal pain.[...](AU)

Remaining uterine mesonephric duct cyst in female dog (Canis familiaris) first case report in Brazil / Cisto de ducto mesonéfrico uterino remanescente em cadela (Canis familiaris) - primeiro relato de caso no Brasil / Quiste remaneciente del ducto mesonéfrico uterino en perra (Canis familiaris) primero relato del caso en Brasil

The aim of work was to describe a remaining uterine mesonephric duct cyst in female Pinscher dog, with 8 years old. The main complaint of the owner was no heat at least 18 months. Clinical examination revealed presence of cysts in all teats, confirmed by cytopathologic exam. Haemogram, serum biochemical exams, urinalysis, radiographs of the thorax and abdominal ultrasound were performed and no changes were observed. During the ovaryhysterectomy was observed endometrial hyperplasia and the histopathologic diagnosis was remaining uterine mesonephric duct cyst associated with discrete endometrial hyperplasia. Was concluded that adequate histopathologycal identification of the uterine mesonephric duct cyst is crucial so do not mistake with neoplasia.(AU)

O objetivo do trabalho foi descrever um caso de cisto de ducto mesonéfrico remanescente uterino em cadela da raça Pinscher, 8 anos de idade. A principal queixa do proprietário foi ausência de cio com duração de 18 meses. No exame físico evidenciou-se presença de cistos em todos os tetos, confirmado pelo exame citopatológico. Foi realizado hemograma, exames de bioquímica sérica, urinálise, exame radiográfico do tórax e ultrassom abdominal, e não foram observadas alterações. Durante o procedimento de ovário-histerectomia, foi observada hiperplasia endometrial e o diagnóstico histopatológico foi de cisto de ducto mesonéfrico remanescente uterino associado à hiperplasia endometrial discreta. Concluiu-se que a identificação histopatológica adequada do cisto de ducto mesonéfrico uterino é crucial para que o mesmo não seja confundido com neoplasia.(AU)
