Plantar vein thrombosis: an uncommon cause of plantar foot pain / Trombose venosa plantar: uma causa incomum de dor em região plantar

INTRODUCTION: Plantar vein thrombosis is a rare condition that can lead to pain, edema, and walking difficulties. It presents a series of predisposing factors, such as recent surgeries, the use of oral contraceptives, and local trauma, among others. Imaging tests are essential for the right diagnosis, and ultrasonography is the modality of choice. As for treatment, there is no consensus in the literature. REPORT: Case of a 30-year-old patient who sought emergency medical care complaining of sudden severe pain in the plantar region of her right foot with walking difficulties. On physical examination, hyperalgesia was observed in the plantar region, irradiating to the calf, associated with swelling. Color Doppler imaging identified an acute thrombus in the medial plantar vein. Rivaroxaban was initially prescribed and replaced by acetylsalicylic acid after three months. The treatment was effective, and the patient was discharged after 11 months. CONCLUSION: Plantar vein thrombosis is a rare condition and has a wide range of differential diagnoses so physicians must maintain a high level of clinical suspicion. To improve diagnosis and treatment, it would be necessary to include plantar veins in the investigation protocols of patients suspected of having Deep Venous Thrombosis, besides additional clinical research for improving treatment.

INTRODUÇÃO: A trombose de veias plantares é uma condição rara que pode cursar com dor, edema e dificuldade na deambulação. Apresenta uma série de fatores predisponentes, como cirurgias recentes, uso de anticoncepcional oral, trauma local, entre outros. A realização de exame de imagem é essencial para o diagnóstico, sendo a ultrassonografia a modalidade de escolha. Quanto ao tratamento, não há consenso na literatura. RELATO: Relatamos o caso de uma paciente de 30 anos que procurou atendimento médico de urgência com queixa de dor de forte intensidade, súbita, em região plantar do pé direito com dificuldade de deambulação. Ao exame físico, observou-se hiperalgesia em região plantar com irradiação para panturrilha, associada a empastamento da mesma. O ecodoppler colorido identificou trombo agudo em veia plantar medial. Optou-se pela prescrição de rivaroxabana, a qual foi substituída por ácido acetilsalicílico após três meses. A paciente evoluiu bem e recebeu alta do tratamento após 11 meses. CONCLUSÃO: A trombose de veias plantares é rara e tem uma alta gama de diagnósticos diferenciais, de forma que o profissional médico deve manter um alto nível de suspeição clínica. Para aperfeiçoar seu diagnóstico e tratamento, seria necessária a inclusão das veias plantares aos protocolos de investigação de pacientes com suspeita de Trombose Venosa Profunda, e pesquisas clínicas que elucidassem os melhores métodos terapêuticos.

Application value of imaging examination in the diagnosis of Muller-Weiss disease / 中国骨伤

OBJECTIVE@#To analyze radiological characteristics of Muller-Weiss disease, evaluate the clinical value of the imaging examination in diagnosis of Muller-Weiss disease.@*METHODS@#The imaging data of 26 patients with Muller-Weiss disease were collected from September 2015 to August 2020, including 7 males and 19 females, aged 43 to 68 years old with an average of (52.7±4.6) years old. In the X-ray examination observed the shape and position of the navicular bone. The talar-first metatarsal angle(TFM) was measured on the weight-bearing anteroposterior radiograph. The arch angle and angle between mid-axis of talus and mid-axis of the first metatarsal(Meary angle) were measured on the weight-bearing lateral radiographs. The morphology, density, adjacent joint space and position of the navicular bone were evaluated by computed tomography(CT), and magnetic resonance imaging(MRI) was used to observe the shape, signal, cartilage and surrounding soft tissue changes of the navicular bone.@*RESULTS@#Among 26 patients, 21 cases were unilateral and 5 cases were bilateral;X-ray examination showed that the lateral part of navicular bone of foot was compressed and flattened, showing"comma like"or"drop like", navicular moved to the medial side, partial fragmentation of bone, peripheral articular hyperplasia, uneven density and narrowing of relationship gap. According to Meary angle and deformity degree of the affected foot on the lateral X-ray of the load-bearing foot, Maceira staging was performed. There were 0 cases in stageⅠ, 2 cases in stage Ⅱ, 11 cases in stage Ⅲ, 9 cases in stage Ⅳand 4 cases in stage Ⅴ. CT examination showed bone fragmentation, medial displacement of navicular bone and formation of the talocalcaneal joint. MRI examination showed the irregular shape and uneven signal of navicular bone, narrowing of joint space, talocalcaneal joint surface hyperplasia and cartilage destruction, tarsal joint effusion and swelling of surrounding soft tissue.@*CONCLUSION@#Muller-Weiss disease has specific imaging manifestation, and an accurate diagnosis can be made based on the patient's age, gender, and clinincal history. Preoperative imaging examination can stage the disease, help clinicians to formulate better surgical plans, and postoperative imaging examination can better evaluate the surgical effect.

Dermoscopy of skin infestations and infections (entomodermoscopy) - Part II: viral, fungal and other infections,

Abstract In addition to the infestations and bacterial infections reported in part I, the study of entomodermoscopy also involves descriptions of dermoscopic findings of a growing number of viral and fungal infections, among others. In this article, the main clinical situations in viral infections where dermoscopy can be useful will be described, that is in the evaluation of viral warts, molluscum contagiosum, and even in recent scenarios such as the COVID-19 pandemic. As for fungal infections, dermoscopy is particularly important, not only in the evaluation of the skin surface, but also of skin annexes, such as hairs and nails. The differential diagnosis with skin tumors, especially melanomas, can be facilitated by dermoscopy, especially in the evaluation of cases of verruca plantaris, onychomycosis and tinea nigra.

The plantar support aims to pronounce the hindfoot and immobilize the talo-navicular, and naviculo-cuneiform joints or both at the same time, as an alternative to the valguizing osteotomy of the calcaneus and arthrodesis. The clinical and radiological characteristics of 10 cases of EMW in 8 patients under study are analyzed and the results obtained are evaluated. The manufacturing process of the plantar supports is commented, as well as the materials used. The sample size is not significant, however, preliminary, conservative treatment is possible in certain cases of EMW to relieve pain, improve gait dynamics and limit disease progression in the short-term.

Papillary intralymphatic angioendothelioma: Dabska tumor

Abstract Papillary intralymphatic angioendothelioma (Dabska tumor) is a rarely metastasizing lymphatic vascular neoplasm that usually affects children and young adults. The majority of these cases occur in soft tissues of extremities, and to date less than 40 cases have been described. Despite the generally indolent evolution, can be locally invasive with the potential to metastasize. We describe a case of a young woman presenting with a plantar lesion, for 9 months and histological diagnosis of Dabska tumor. This neoplasm should be considered in the differential diagnosis of vascular dermatoses, allowing early diagnosis and treatment. Long-term follow-up should be performed.

Factores asociados con dolor severo en pacientes con fascitis plantar: Un análisis de relaciones / Factors associated with severe pain in patients with plantar fasciitis: An association analysis

Objetivo: Describir los factores asociados con niveles de dolor mas severo en una cohorte de pacientes con fascitis plantar. El objetivo secundario fue analizar cuales de estos factores estaban asociados con niveles mas altos de mejoria clinica luego del tratamiento conservador. Materiales y Métodos: Se evaluo a una cohorte prospectiva de pacientes con diagnostico de fascitis plantar. Cada participante completo una escala ordinal visual de dolor (del 1 al 10) para dolor del primer paso y dolor al final del dia y encuestas FFI-R (Foot Function Index-Revised). Tambien se realizo una evaluacion demografica. La dorsiflexion de la articulacion del tobillo, el rango de movilidad de la primera articulacion metatarsofalangica, la rigidez del gastrocnemio y el angulo popliteo tambien se evaluaron de manera estandar. Resultados: Se incluyo a 214 pacientes. El 64% eran hombres (118 pacientes), la media de la edad era de 49.67 anos (DE 13.16) y el indice de masa corporal promedio, de 28,53 (DE 5,18). En el analisis multivariado, se observo que el riesgo de un puntaje ≥8 en la escala de dolor aumento cuando el paciente refirio estar de pie por mas de 6 h (OR 1,17; p = 0,03; IC95% 1,02-1,35). El riesgo de un puntaje >8 fue mayor cuando el grado de dorsiflexion del tobillo fue <0° (OR 1,20; p = 0,03; IC95% 1,02-1,41). Conclusión: Nuestros hallazgos apoyan indirectamente la hipotesis de que la dorsiflexion limitada del tobillo juega un papel como factor de riesgo asociado a un puntaje ≥8 en la escala de dolor, en los casos de fascitis plantar. Nivel de Evidencia: IV

Objective: The main purpose of our study was to describe the factors associated with more severe pain levels in a cohort of patients with plantar fasciitis (PF). The secondary purpose of this study was to determine which of these factors were associated with higher levels of clinical improvement after conservative therapy. Materials and Methods: We conducted a prospective study in a cohort of patients with PF. Each participant completed an ordinal pain scale (1-10) for first-step pain and end-of-day pain, and Foot Function Index-Revised (FFI-R) surveys at enrollment. Also, patient demographics were evaluated. The ankle joint dorsiflexion, the range of motion (ROM) for the first metatarsophalangeal joint (MTPJ), the gastrocnemius tightness, and the popliteal angle were evaluated through standard tests. Results: Our study included 214 participants, of which 64% (118 patients) were males, the average age was 49.67 years (SD 13.16) and the average BMI was 28.53 (SD 5.18). The multivariate analysis showed that the risk of having a Visual Analog Scale (VAS) score ≥8 increased when the patient reported standing for more than 6 hours (OR=1.17; P=0.03; CI95%: 1.02-1.359). The risk of a >8-VAS score was higher when the level of ankle dorsiflexion was <0 (OR=1.20; P=0.03; CI95%: 1.02-1.41). Conclusion: Our findings indirectly support the hypothesis that limited ankle dorsiflexion ROM plays a role as a risk factor associated with VAS scores ≥8 in PF patients. Level of Evidence: IV

Análise do equilíbrio postural estático e da intensidade das dores musculoesqueléticas após o uso de palmilhas proprioceptivas por militares do serviço ostensivo / Análisis del equilibrio postural estático y de la intensidad de los dolores musculoesqueléticas después del uso de plantillas propioceptivas por militares del servicio ostensivo / Analysis of static postural balance and of intensity of musculoskeletal pains after the use of proprioceptive insoles by ostensive service militaries

RESUMO Para a manutenção do equilíbrio, o organismo utiliza os sistemas visuais, vestibulares e proprioceptivos, que enviam informações para o sistema nervoso central acerca das condições do corpo com o objetivo de estabilizá-lo. Este estudo avaliou o efeito das palmilhas proprioceptivas sobre o equilíbrio postural estático e as dores musculoesqueléticas após dois meses de uso, por meio de uma pesquisa analítica longitudinal com 15 militares saudáveis do sexo masculino com média de idade de 34±7,5 anos. Eles foram submetidos à avaliação do equilíbrio por meio da plataforma Medicapteurs® e pelo protocolo CNT. Não houve diferença estatística para os desvios do corpo e velocidade do centro de pressão. A pressão plantar teve mudança estatisticamente significante para o pé esquerdo e o pé direito correspondendo a p=0,0001 e p=0,0007, respectivamente. Houve redução das médias de dores nos joelhos, pés e calcanhares e diminuição significativa da dor lombar, com p=0,0180. O equilíbrio estático não foi alterado significativamente com o uso das palmilhas proprioceptivas pelos militares, contudo elas proporcionaram melhor redistribuição das pressões plantares e parecem atenuar as dores musculoesqueléticas das extremidades inferiores. Por isso as palmilhas podem ser consideradas para esse grupo uma terapêutica de prevenção contra lesões relacionadas à sua atividade laboral.

RESUMEN Para mantener el equilibrio el cuerpo utiliza los sistemas visuales, vestibulares y propioceptivos, que envían información al sistema nervioso central sobre las condiciones del cuerpo para estabilizarlo. Este estudio evaluó el efecto de las plantillas propioceptivas sobre el equilibrio postural estático y los dolores musculoesqueléticas después de dos meses de uso, a través de una investigación analítica longitudinal con 15 soldados sanos con una edad media de 34±7.5 años. Ellos fueron sometidos a evaluación de equilibrio a través de la plataforma Medicapteurs® y por el protocolo CNT. No hubo diferencia estadística para las desviaciones del cuerpo y para la velocidad del centro de presión. La presión plantar tuvo un cambio estadísticamente significativo para el pie izquierdo y el pie derecho correspondiente a p=0.0001 y p=0.0007, respectivamente. Hubo una reducción en las promedio de los dolores en las rodillas, pies y talones y una disminución significativa en el dolor lumbar, con p=0.0180. El equilibrio estático no se modificó significativamente con el uso de plantillas propioceptivas por los militares, sin embargo, proporcionaron una mejor redistribución de las presiones plantares y parecen ablandar los dolores musculoesqueléticas en las extremidades inferiores. Por lo tanto las plantillas pueden considerarse para ese grupo como una terapia de prevención contra lesiones relacionadas con su actividad laboral.

ABSTRACT To maintain the balance, the body uses visual, vestibular and proprioceptive systems, which send information to the central nervous system about the body's conditions in order to stabilize it. This study evaluated the effect of proprioceptive insoles on static postural balance and musculoskeletal pains after two months of use, through a longitudinal analytical study with 15 healthy male soldiers with a mean age of 34±7.5 years. They were subjected to balance evaluation through the Medicapteurs® platform and by CNT protocol. There was no statistical difference for the deviations of the body and speed of the center of pressure. Plantar pressure had a statistically significant change for the left and the right feet, corresponding to p=0.0001 and p=0.0007, respectively. There was a reduction in the mean values of the pains in the knees, feet and heels and a significant decrease in lumbar spine pain, with p=0.0180. The static balance was not significantly altered with the use of proprioceptive insoles by the militaries; however, these insoles provided a better redistribution of plantar pressures and seem to attenuate the musculoskeletal pains of the lower extremities. Therefore, insoles can be considered as a prevention therapy against injuries for this group related to their work activity.

Impact of high-energy diets on the rumen environment and digital cushion in confined cattle / O impacto de dietas de alto valor energético sobre o ambiente ruminal e o tecido digital em bovinos confinados

This study aimed to identify gross and microscopic changes, caused by high-energy diets, in the rumen environment and hoof of confined beef cattle. The study sample comprised 40 confined heifers (Bos taurus) with no disease history divided into four experimental groups using different diets: Group 1 (D1, control), 48:52 forage:concentrate ratio; Group 2 (D2), 30:70 forage:concentrate ratio; Group 3 (D3), 30:70 forage:concentrate ratio + sucrose; Group 4 (D4), 100% concentrate. All animals underwent clinical examination, assessment of ruminal fluid pH and lameness, and sample collection after slaughter for histopathology of the hoof laminae and digital cushion and ruminal tissue. All dependent variables of the study were compared using the SPSS 20.0 statistical software. The variables that did not show normality (HR, RM, ST, and CRT) were compared with application of the Kruskal-Wallis test followed by the Dunnet's multiple comparison test. All other variables were submitted to analysis of variance (ANOVA) followed by Tukey's test. The different diets had an impact on the rumen environment (p<0.05) of the heifers assessed, with momentary general depression in the first 12 h after sucrose induction (D3), as well as mild clinical signs in D4. The animals in D3 and D4 presented lower motility (p<0.05) and ruminal pH (p<0.01) than those in D1. Of the 40 heifers, 27.5% (n=11) showed gross lesions in the epithelium of ruminal pillars, whereas 22.5% (n=9) of those in D3 and D4 presented these lesions. Sole corium thickness varied between heifers in D3 compared with those in D1 and D2 (p<0.05). Therefore, high-energy diets, as used in this study, alter some clinical parameters and the rumen environment, causing lesions in the rumen mucosa, and of lesser intensity, in the hoof corium and laminae, suggestive of laminitis.(AU)

O objetivo deste trabalho foi identificar alterações macroscópicas e microscópicas provocadas por dietas de alto valor energético no ambiente ruminal e casco de bovinos de corte (Bos taurus) em confinamento. Foram utilizadas 40 novilhas mantidas em confinamento, sendo divididas em 4 grupos experimentais: Grupo D1(controle) - 48% de volumoso e 52% de concentrado; Grupo D2 - 30% de volumoso e 70% de concentrado; Grupo D3 - 30% de volumoso e 70% de concentrado + sacarose; Grupo D4 - 100% de concentrado. Foi realizado exame clínico dos animais, avaliação do pH ruminal, da claudicação, além de coletas de amostras post-mortem para análises histopatológicas da região laminar do casco, coxim digital e do rúmen. Todas as variáveis dependentes do estudo foram comparadas por meio do software estatístico SPSS 20.0. As variáveis sem normalidade (FC, MR, Tc e TPC) foram comparadas pelo teste de Kruskal Wallis, seguido pelo teste de comparação múltipla de Dunnet. Todas demais foram submetidas a análise de variância (ANOVA), seguida pelo teste de Tukey. Foi observado impacto das distintas dietas ao ambiente ruminal (p<0,05). Os grupos D3 e D4 exibiram menor motilidade (p<0,05) e pH ruminal (p<0,01). 27,5% (n=11) dos animais tiveram registros macroscópicos de lesões no epitélio dos pilares ruminais enquanto que os submetidos às dietas 3 e 4 foi observada ocorrência de 22,5% (n=9) de lesões macroscópicas no rúmen. As espessuras do córium solear variaram entre os grupos que receberam a indução de sacarose em relação ao grupo controle e novilhas alimentadas com a dieta 2 (p<0,05). Sendo assim dietas com elevada densidade energética, na condição em que foi empregada, alteraram alguns parâmetros clínicos e o ambiente ruminal, provocando lesões na mucosa do rúmen e de pouca intensidade no córium e tecido laminar, sugestiva de laminite.(AU)

ABSTRACT The purpose of this study is to analyze the effects of using customized insoles and leg and foot exercises on the feet of patients with neuropathy caused by leprosy. Thirty volunteers diagnosed with leprosy were assigned to one of three groups: (1) Exercise group (n=10): performed exercises for the intrinsic muscles of the foot; (2) Insole group (n=10): used insoles to correct foot positioning; (3) Insole and Exercise group (n=10): used insoles and performed an exercise routine. The results of the treatments were analyzed with photogrammetry using the Alcimagem® and AutoCAD® programs. Left hindfoot posture changed after treatment in the Exercise and Insole groups (hindfoot, pre versus post <0.001). We also found that combining exercise and insoles did not alter the alignment of the feet during the study's evaluation period (customized insoles and exercises, pre versus post <0.05), which suggests that follow-up for more than four months may be needed. The left hindfoot's alignment can be changed with supervised exercises and the use of insoles.

RESUMO O objetivo deste estudo é analisar a influência do uso de palmilhas personalizadas e exercícios para perna e pés nos ângulos do antepé, retropé e arco plantar de pacientes com neuropatia causada por hanseníase. Trinta voluntários diagnosticados com hanseníase foram designados para um dos três grupos: (1) grupo exercício (n=10): realização de exercícios para pernas e pés; (2) grupo palmilha (n=10): utilização de palmilhas para corrigir o posicionamento do pé; (3) grupo palmilha e exercícios (n=10): uso de palmilhas associado a uma rotina de exercícios. O resultado dos tratamentos foi analisado por meio de fotogrametria, com os softwares Alcimagem e AutoCAD. A postura do retropé esquerdo foi modificada após o tratamento no "grupo exercício" e "grupo palmilha" (retropé, pré versus pós<0,001). Também foi observado que a combinação entre exercícios e palmilhas não alterou o alinhamento dos pés durante o período de avaliação do estudo (palmilha e exercícios, pré versus pós>0,05), o que sugere que o acompanhamento por mais de quatro meses pode ser necessário. Assim, o uso isolado de exercícios supervisionados ou de palmilhas altera o alinhamento do retropé, como aferido por fotogrametria.

RESUMEN El presente estudio tiene como objetivo analizar la influencia del uso de plantillas personalizadas y la práctica ejercicios de piernas y pies en los ángulos del antepié, del retropié y del arco plantar de pacientes con neuropatía debido a lepra. Treinta voluntarios diagnosticados con lepra fueron asignados a uno de estos tres grupos: (1) grupo de ejercicios (n=10): hacer ejercicios de piernas y pies; (2) grupo de plantillas (n=10): utilizar plantillas para corregir la posición del pie; (3) grupo de plantillas y ejercicios (n=10): utilizar plantillas asociadas con una rutina de ejercicios. Los resultados de los tratamientos se analizaron mediante fotogrametría, con los softwares Alcimagem y AutoCAD. La postura del retropié izquierdo se modificó tras el tratamiento en el "grupo de ejercicios" y en el "grupo de plantillas" (retropié, pre versus pos <0,001). También se observó que la combinación de ejercicios y plantillas no alteró la alineación del pie durante el período de evaluación del estudio (plantilla y ejercicios, pre versus pos >0,05), lo que sugiere que puede requerirse seguimiento durante más de cuatro meses. Por lo tanto, la práctica aislada de ejercicios supervisados o el uso de plantillas altera la alineación del retropié, medido por fotogrametría.

Actinomicetoma plantar en un paciente sin factores de riesgo / Plantar actinomycetoma in a patient without risk factors

Resumen Se presenta un caso clínico de un actinomicetoma plantar en un paciente sin factores de riesgo, cuyo diagnóstico fue realizado mediante una biopsia de tejido plantar por sospecha de una neoplasia. Dado que el paciente no respondió satisfactoriamente a la terapia de primera línea, debió completar 24 semanas de tratamiento con doxiciclina, a lo cual evolucionó favorablemente. Finalmente, se desarrolla una breve discusión sobre los micetomas plantares.

A case of plantar actinomycetoma without risk factors is presented, which was diagnosed by hystopatological analysis of a foot biopsy because of the suspicion of neoplasia. Since the patient did not fully respond to the first-line therapy antibiotics, a 24-weeks doxycycline regime was started, achieving a satisfactory response. Finally, a brief discussion on plantar mycetomas is presented.

Melioidosis en Colombia, descripción de un caso clínico y consideraciones epidemiológicas / Melioidosis in Colombia, description of a clinical case and epidemiological considerations

Resumen La melioidosis es una enfermedad infecciosa causada por Burkholderia pseudomallei cuyo diagnóstico clínico puede ser difícil debido a su variada presentación clínica y a las dificultades del diagnóstico microbiológico, por lo cual pueden requerirse técnicas moleculares para su adecuada identificación una vez se sospecha su presencia. Son pocos los antibióticos disponibles para el tratamiento de esta enfermedad y, además, deben usarse durante un tiempo prolongado. Aunque se conoce por ser endémica en Tailandia, Malasia, Singapur, Vietnam y Australia, en Colombia se han reportado algunos pocos casos. Se presenta un caso de melioidosis en la región norte de Colombia, se hace una revisión de las características clínicas y el tratamiento, y se describe la epidemiología local de esta enfermedad.

Abstract Melioidosis is an infectious disease caused by Burkholderia pseudomallei whose clinical diagnosis can be difficult due not only to its varied clinical presentation but also to the difficulties in the microbiological diagnosis.Thus, it may be necessary to use molecular techniques for its proper identification once it is suspected. There are few antibiotics available for the treatment of this disease, which must be used over a long period of time. Although it is known to be endemic in Thailand, Malaysia, Singapore, Vietnam, and Australia, in Colombia there are few reported cases. We describe a case of melioidosis in the northern region of Colombia. Additionally, we review its clinical characteristics and treatment and we describe the local epidemiology of this disease.

Isolation, cultivation and immunofluorescence characterization of lamellar keratinocytes from equine hoof by using explants / Isolamento, cultivo e caracterização por imunofluorescência de queratinócitos lamelares de casco equino utilizando explantes

The importance of the hoof to the horse health is clear, and the current knowledge regarding the cellular aspects of hoof keratinocytes is poor. Studies on equine keratinocyte culture are scarce. Developing keratinocyte cultures in vitro is a condition for studies on molecular biology, cell growth and differentiation. Some methods have already been established, such as those for skin keratinocyte culture. However, few methodologies are found for lamellar keratinocytes. The objective of this study was to standardize the equine hoof keratinocyte isolation and cultivation, and then characterize the cell immunophenotype. For this, the primary culture method used was through explants obtained from three regions of the equine hoof (medial dorsal, dorsal, and lateral dorsal). After the cell isolation and cultivation, the cell culture and its explants were stained with anti-pan cytokeratin (pan-CK) (AE1/AE3), vimentin (V9), p63 (4A4), and Ki-67 (MIB-1) antibodies. Cells were grown to third passage, were positive for pan-CK, p63 and Ki-67, and few cells had vimentin positive expression. As for the explants, the epidermal laminae were not stained for vimentin or Ki-67. However, some cells presented positive pan-CK and p63 expression. This study demonstrated the viability of lamellar explants of equine hooves as a form of isolating keratinocytes in primary cultures, as well as characterized the proliferation ability of such keratinocytes in monolayers.(AU)

É notória a importância do casco na saúde dos equinos, mas o conhecimento em nível celular é pouco entendido. Estudos envolvendo o cultivo de queratinócitos equinos são escassos. Sabe-se que o desenvolvimento de cultivos de queratinócitos in vitro é uma condição para estudos sobre a biologia molecular, crescimento e diferenciação celular. Alguns métodos já estão estabelecidos, como para cultivo de queratinócitos de pele, mas poucas metodologias são encontradas para queratinócitos lamelares. O objetivo desse estudo foi padronizar o cultivo de queratinócitos provenientes de casco equino visando futuramente associar ao estudo da medicina regenerativa para assim estabelecer um modelo experimental in vitro e indicar o uso criterioso de terapias regenerativas para a laminite equina. Desta forma, o cultivo em monocamada e a caracterização de queratinócitos lamelares foram realizados. Para isso, o método de cultura primária utilizado foi através de explantes obtidos de três regiões do casco (dorso-medial, dorsal e dorso-lateral). As células foram caracterizadas para os marcadores anti pan-cytokeratin (AE1/AE3), vimentin (V9), p63 (4A4) e Ki-67 (MIB-1) nos cultivos e nos explantes. As células foram cultivadas até terceira passagem, tendo marcação positiva para pan-CK, p63 e Ki-67 e fraca marcação para vimentina. Já as lâminas epidermais não tiveram marcação de vimentin e Ki-67, porém marcaram acentuadamente para pan-CK e p63. Este estudo demonstrou a exiquibilidade do uso de explantes lamelares do casco de equinos, como forma de isolamento de queratinócitos em cultivos primários, bem como caracterizou a habilidade de proliferação desses queratinócitos em monocamada.(AU)

Estudo da técnica de venografia dos dígitos de vacas / Study of Venography technique in digits of cows

O objetivo deste estudo foi descrever a técnica de venografia retrógrada podal em vacas, comparando os acessos da veia digital dorsal comum III com a digital comum II ou IV, nos membros torácicos e pélvicos, mediante a administração de dois diferentes volumes de contraste. Foram utilizados 53 membros torácicos e pélvicos de 14 vacas, com o torniquete de borracha posicionado a 5cm proximal aosparadígitos. Administraram-se 10mL do diatrizoato de meglumina em 24 membros (grupo 1), sendo 13 na veia digital dorsal comum III pelo acesso 1 (A1) e 11 na digital II ou IV no acesso 2 (A2). No grupo 2, administraram-se 20mL em 29 membros, sendo 15 pelo A1 e 19 pelo A2. Após a administração do contraste, as radiografias foram repetidas a cada 20 segundos até 120 segundos. O grau de preenchimento vascular foi maior no grupo 2, não diferindo entre membros e acessos venosos. Conclui-se que a administração de 20mL de contraste apresentou melhor preenchimento vascular e radiopacidade, não havendo diferença entre 20 e 120 segundos após a administração do contraste na qualidade radiográfica, independentemente do acesso venoso.(AU)

The aim of this study was to describe the technique of retrograde venography foot in cows, comparing the approaches of the dorsal common digital vein III with the digital commons II or IV, thoracic and pelvic by administering two different volumes of contrast members. Fifty three fore and hindlimbs of 14 cows were used, a rubber tourniquet was placed at 5cm above accessory digit. Diatrizoatemeglumine was administered at 10mL to 24 members (group 1), 13 dorsal common digital vein III for access 1 (A1), and 11 digital II or IV access 2 (A2). In group 2 20mL was administered to 29 members, 15 by 19 in A1 and A2. After contrast administration, the radiographs were repeated every 20 seconds until 120 seconds. The degree of vascular filling was greater in group 2, independent of venous access, member or moment. There was no significant difference in the degree of radiopacity of radiographic images when compared to the venous access, time and a member of both groups. We conclude that administration of 20mL of contrast showed better vascular filling and radiopacity, with no difference between 20 and 120 seconds after contrast administration in independent radiographic quality venous access.(AU)
