RESUMO

Ayurvedic medicines is known to use heavy metals in their preparation. Nagabhasma is one such form of a lead-based medicine. Even though lead is known to be toxic to several systems of the human body, according to Ayurveda, the metallic toxicity of the lead gets nullified and thereby imbibes medicinal property when it is prepared using many herbs and stringent traditional methods. Therefore, the present study is designed to evaluate the effect of such detoxified lead in various stages of authentically prepared Nagabhasma on the histopathology of liver in comparison with lead acetate and commercially available Nagabhasma-administered animals. Less than the human-equivalent doses of Nagabhasma at four intermittent stages of its preparation were administered orally for 30 days and 60 days (short term and long term exposure) to Wistar rats. In another set of experiment, test-material-administered animals were kept under observation for an additional period of two months to record the residual effect. Immediately after the administration and after the observation period, the animals were sacrificed to collect the liver for histopathological examination. The histopathological results of the immediate and residual effects showed varying alterations in the microarchitecture of the liver as the stages of Nagabhasma preparation advanced. The final product (stage 4 bhasma), showed very less toxic effect in comparison with other stages. In conclusion, the results state that, by following the traditional procedures while preparing Nagabhasma, the metallic lead gets converted into non-toxic organometallic compound

RESUMO

The glenoid labrum has an important role in glenohumeral joint stability, yet its morphometric parameters are seldom reported. This study aimed to (I) investigate the thickness and height of the glenoid labrum, and (ii) determine whether there is any significant difference between side and sex. A total of 140 shoulders (30 male and 40 female cadavers, average age of 81.5 years) were obtained for this study. All muscles and blood vessels surrounding the glenohumeral joint, as well as the fibrous capsule, were inspected and then removed to expose the glenoid fossa with the labrum attached. Measurement of labral height and thickness at the superior (12 o'clock), anterior (3 o'clock), inferior (6 o'clock) and posterior (9 o'clock) regions were taken. Gender, side and thickness and height measurements of the glenoid labrum were double- entered into the Statistical Package for Social Sciences. ANOVA and MANOVA tests were conducted to determine statistical significance, which was set at P<0.05. Significant differences in thickness (at the superior, inferior and posterior aspects) and height (at the superior and inferior aspects) of the glenoid labrum were observed between males and females, being thicker and taller in males in all regions. Based on the side of the limb, no differences in labral thickness and height were observed with respect to side. The current observations confirm that the glenoid labrum height and thickness are associated with sex, but not with side

RESUMO

Although a sublabral foramen does not require treatment, its association with age, sex or side remains unknown. Therefore, the aim of the current study was to investigate the incidence of a sublabral foramen and age, sex and side in a British population. A total of 140 shoulders (30 male and 40 female cadavers, with an average age of 81.5 years), were obtained from the Centre for Anatomy and Human Identification University of Dundee, in accordance with the Human Tissue (Scotland) Act 2006. All muscles and blood vessels surrounding the glenohumeral joint, as well as the fibrous capsule, were inspected and then removed to expose the glenoid fossa with the glenoid labrum attached. The gender, age, side and presence of a sublabral foramen were double-entered into the Statistical Package for Social Sciences (Version 21; IBM, Armonk, NY, USA). Chi Square tests were conducted to determine statistical significance, which was set at P<0.05. A sublabral foramen was observed in 28.6% (n=40) of shoulders, being marginally more in females than males. A sublabral foramen was more common in elderly individuals (>70 years old), no significant difference being observed between the presence of a sublabral foramen and age. It was also more common on the right than the left side in both genders with no significant difference between the presence of a sublabral foramen and sex or side. The current observations confirm that a sublabral foramen was more common in older individuals, but was not significantly different from other age groups

RESUMO

Purpose: To establish a relationship between the diameter and depth position of vessels in the superior and inferior corneo-scleral limbus using ultra-high resolution optical coherence tomography (UHR-OCT). Methods: Volumetric OCT images of the superior and inferior limbus were acquired from 14 healthy subjects with a research-grade UHR-OCT system. Differences in vessel diameter and depth between superior and inferior limbus were analyzed using repeated measured ANOVA in SPSS and R. Results: The mean (± SD) superior and inferior diameters were 29 ± 18μm and 24 ± 18μm respectively, and the mean (± SD) superior and inferior depths were 177 ± 109μm and 207 ± 132μm respectively. The superior limbal vessels were larger than the inferior ones (RM-ANOVA, p = 0.004), and the inferior limbal vessels were deeper than the superior vessels (RM-ANOVA, p = 0.041). There was a positive linear association between limbal vessel depth and size within the superior and inferior limbus with Pearson correlation coefficients of 0.803 and 0.754, respectively. Conclusion: This study demonstrated that the UHR-OCT was capable of imaging morphometric characteristics such as the size and depth of vessels in the limbus. The results of this study suggest a difference in the size and depth of vessels across different positions of the limbus, which may be indicative of adaptations to chronic hypoxia caused by the covering of the superior limbus by the upper eyelid. UHR-OCT may be a useful tool to evaluate the effect of contact lenses on the microvascular properties within the limbus (AU)


Objetivo: Establecer la relación entre el diámetro y la profundidad de los vasos del limbo esclerocorneal superior e inferior mediante tomografía de coherencia óptica de ultra-alta resolución (UHR-OCT). Métodos: Se adquirieron 256 conjuntos de imágenes del limbo superior e inferior en 14 sujetos, mediante UHR-OCT. Se analizaron las diferencias en cuanto a diámetro y profundidad del vaso entre el limbo superior e inferior utilizando ANOVA de medidas repetidas en SPSS y R. Resultados: Los diámetros medios (± DE) superior e inferior fueron de 29μm ± 18μm y 24μm ± 18μm respectivamente, y las profundidades medias (± DE) superior e inferior fueron de 177μm ± 109μm y 207m ± 132μm respectivamente. Los vasos del limbo superior fueron de mayor tamaño que los del limbo inferior (RM-ANOVA, p = 0,004), y los vasos del limbo inferior fueron más profundos que los del limbo superior (RM-ANOVA, p = 0,041). Se produjo una asociación lineal positiva entre la profundidad y el tamaño del vaso dentro del limbo superior e inferior, con coeficientes de correlación de Pearson de 0,803 y 0,754, respectivamente. Conclusión: Este estudio demuestra que UHR-OCT fue capaz de obtener imágenes de las características morfométricas tales como tamaño y profundidad de los vasos del limbo. Los resultados de este estudio sugieren una diferencia de tamaño y profundidad de los vasos en las diferentes posiciones del limbo, que puede ser indicativa de adaptaciones a la hipoxia crónica causada por el cubrimiento del limbo superior por parte del párpado superior. UHR-OCT puede ser una herramienta de utilidad para evaluar el efecto de las lentes de contacto sobre las propiedades microvasculares del limbo esclerocorneal (AU)

RESUMO

Background: Avoidance from palatal blood vessel rupture is a major concern during the palatal soft tissue graft surgery. There is no defined chair-side and case-specific palatal blood vessel detection approach to facilitate the harvesting process. The objective of this pilot study is to assess the feasibility of a near-infrared vein visualization system in the screening process of palatal blood vessels. Material and Methods: An extraoral vein visualization device (AccuVein AV400) was applied to a total of 304 hemi-maxilla of 152 individuals by two blind examiners. The study groups were classified according to their maximum inter-incisal measurements. The distances between the coronal border of the vessel image and the mid-palatal gingival margins of the adjacent teeth were measured and in each group. The correlations among the measurements were evaluated within groups. Results: The blood vessel to the adjacent teeth measurements exhibited no statistical difference between both examiners in all subjects (p<0.001). Correlations between the examiners gradually increased in all groups as the mouth opening rates of the subjects were increased (p<0.001). Conclusions: In the current state, screening of the palatal blood vessels via near-infrared vein visualization technology seems to be not suitable for every individual due to the restrictive effect of mouth opening. However, the promising results of this preliminary study demonstrated increasing consistency between the measurements of the examiners as the inter-incisal distance increase which emphasized the need an intraoral version of the device. Considering the lack of local decision-making technology for the detection of palatal blood vessels, further studies are required for development and optimization of these systems (AU)

RESUMO

Antecedentes y Objetivo. En la Cirugía Plástica es fundamental una adecuada planificación preoperatoria y un conocimiento de la variabilidad anatómica de los vasos perforantes de la mama, que junto con las modificaciones provocadas por cirugías previas, hacen que el disponer de un sistema fiable de localización preoperatoria de los vasos sea de enorme utilidad para elegir la mejor técnica quirúrgica a utilizar. El objetivo del presente trabajo es determinar si la mamografía 3D/tomosíntesis es el método de elección para visualizar el patrón vascular del complejo areola-pezón (CAP) en cirugía mamaria secundaria: mamoplastia de aumento, reductora y mastopexia con o sin implantes, para evitar complicaciones desde el punto de vista de su irrigación y elegir así la mejor vía de acceso para la cirugía secundaria. Material y Método. Llevamos a cabo un estudio clínico prospectivo, longitudinal y descriptivo sobre una muestra de 31 pacientes, todas mujeres sanas con antecedente de cirugía mamaria previa, a quienes se les realizó mamografía en 3 dimensiones (tomosíntesis) para determinar su patrón vascular mamario. Resultados. Los patrones vasculares dominantes fueron los superiores (58.06%), las cicatrices encontradas fueron principalmente periareolares (48.3%) y las cirugías secundarias realizadas, dependiendo de los patrones vasculares recogidos en la tomosíntesis, fueron pedículos superiores (87%). Las cicatrices no indicaron el tipo de patrón vascular usado en la cirugía previa. No encontramos ningún caso de necrosis del CAP. Conclusiones. El uso de la tomosíntesis como método de imagen en la evaluación preoperatoria de la vascularización en mamoplastias de revisión representa una herramienta útil para planificar la técnica quirúrgica a realizar en vista de que ofrece una información real y exacta, lo que conlleva evitar complicaciones vasculares como necrosis del CAP, garantizando una cirugía segura y disminuyendo las complicaciones (AU)


Background and Objective. In Plastic Surgery is appropriated a preoperative planning and the knowledge of the anatomical variability of perforating vessels of the breast, that along with the changes caused by previous surgery, may cause that to have a reliable preoperative localization of the vessels be extremely useful to choose the best surgical technique to be used. The aim of the present research is to determine if the 3D mammography/tomosynthesis is the best method for determination of vascular pattern of the nipple-areola complex (NAC) in secondary breast surgery: augmentation, reduction mammoplasty and with or without implants mastopexy, in order to avoid NAC vascular complications, and in this way, to select the best access to secondary surgery. Methods. We conduct a prospective, longitudinal and descriptive clinical study, with a sample consisted of 31 healthy female patients with previous breast surgery to whom 3 dimensional mammography (tomosynthesis) was performed to determine the mammary vascular pattern. Results. The dominant vascular patterns were superior (58.06%), the scars founded were mostly periareolar (48.3%) and the performed secondary surgeries, depending on the vascular pattern reported in the tomosynthesis, were superior pedicles (87%).The scars did not indicate the vascular pattern used in the previous surgery. NAC necrosis was not reported. Conclusions. The use of tomosynthesis imaging method in the preoperative evaluation of vascularization in secondary mammoplasty represents an useful tool for surgical planification as it offers a real and exact information, what leads to avoid vascular complications such as NAC necrosis, guaranteeing a safe surgery (AU)

RESUMO

Introducción: Las lesiones causadas por trauma penetrante son una de las principales causas de morbimortalidad en todo el mundo. Para una gestión eficiente y un tratamiento adecuado, es esencial lograr una rápida detección, localización y caracterización de la lesión. Objetivo: Determinar la epidemiología y revisar el manejo perioperatorio de lesiones vasculares periféricas en extremidades durante una década. Material y métodos: Se utilizaron datos de 2006-2015 de un hospital universitario con pacientes con diagnóstico de lesión vascular en extremidades. Resultados: Se reportó un total de 110 casos. En 26 de los pacientes (23,6%) la lesión fue causada por una herida por arma punzo cortante y en 84 pacientes (76,4%) por proyectil de arma de fuego. El sitio lesionado más común fue la extremidad inferior. Veintiséis pacientes (23,6%) no mostraron lesión durante la angiografía. Se identificaron un total de 150 lesiones vasculares. Conclusiones: La arteria más comúnmente lesionada fue la femoral. Los factores predictivos de las lesiones estadísticamente significativos fueron la puntuación de la gravedad de la lesión, el grado de choque y los pacientes con lesiones múltiples. Seis amputaciones reportadas coinciden con un trauma severo. La ausencia de signos duros no descarta la posibilidad de lesión arterial. Se recomienda la reparación con injerto de safena invertido para las lesiones no reparables de manera primaria (AU)


Background: Penetrating trauma injuries are a leading cause of morbidity and mortality worldwide. For efficient management and appropriate treatment, the injuries need to be rapidly detected, located, and characterised. Objective: To describe the epidemiology and review the management of vascular injuries over a 10-year period. Material and methods: Data were used from patients with a diagnosis of vascular injury in extremities between 2006 and 2015 from a university hospital. Results: A total of 110 cases were reported. In 26 (23.6%) patients the injury was caused by a stab wound, and by a gunshot wound in 84 (76.4%) patients. The most common injury site was the lower limb. Twenty-six (23.6%) patients showed no injury in the angiography. A total of 150 vascular injuries were identified. Conclusion: The most commonly injured artery was the femoral. Statistically significant injury predictive factors were the injury severity score, the degree of shock, and patients with multiple injuries. Six amputations reported were associated with severe trauma. The absence of severe signs does not rule out the possibility of arterial injury. Inverted saphenous vein graft repair is recommended for non-repairable injuries (AU)

RESUMO

OBJETIVOS: Conocer las características de la barrera sanguínea del nervio óptico de animales con diabetes inducida por estreptozotocina. MÉTODO: Los nervios ópticos de animales diabéticos y controles se estudiaron mediante microscopia óptica y microscopia electrónica de transmisión. La permeabilidad de los vasos fue determinada mediante la detección de albúmina con inmunofluorescencia indirecta y la expresión de las moléculas del complejo mayor de histocompatibilidad clase II mediante inmunofluorescencia directa. Asimismo, se realizó un análisis morfométrico de la superficie del nervio, el número de vasos y el engrosamiento de la célula endotelial y lámina basal. RESULTADOS: Los microvasos de los nervios ópticos de los animales diabéticos por efecto de la estreptozotocina se caracterizaron por un incremento en el grosor de su pared, conservación de los pericitos, incremento de la transcitosis en la célula endotelial y la presencia de una población importante de macrófagos perivasculares. En general, las manifestaciones del efecto de la hiperglucemia en el nervio óptico fueron más semejantes a las descritas para la microcirculación cerebral que a las descritas para la retina


OBJECTIVE: To study the features of the endoneurial micro-vessels of the optic nerve in streptozotocin-induced diabetic animals. METHODS: Optic nerves from control and streptozotocin-induced diabetic animals were studied by light and transmission electron microscopy. Patency was determined by indirect immunofluorescence albumin detection. The expression of major histocompatibility complex class II molecules was performed by direct immunofluorescence. The endoneurial vessels were counted, and the endothelial cell, the basement membrane, and the surface of the transverse section of the nerve were measured. RESULTS: Vessels of diabetic rats showed vessel wall thickening, preservation of pericytes, an increase in endothelial cell transcytosis, and an increased number of perivascular macrophage cells. It may be concluded that the effects of hyperglycaemia on the inner vessels of the optic nerve are more similar to the cerebral diabetic vessels than to the retinal vessels in diabetic animals

RESUMO

Background: To analyze the face vascularization pattern using B-mode and Doppler ultrasonography, and also propose an arterial vessel mapping. Material and Methods: The investigation was performed on 20 ultrasonography exams of facial vessels through linear and endocavitary transducers. We analyzed and determined the average values for diameters, peak systolic velocity and resistive index of the following arteries: external carotid, lingual, deep lingual, sublingual, facial, submental, inferior labial, superior labial, angular, maxillary inferior alveolar, mental, buccal, greater palatine, infraorbital, superficial temporal, transverse facial and frontal. Results: Data was obtained allowing the analysis of the tissue hemodynamics. We were able to map the vascularization of the face and it was possible to access three arteries of small diameter (0,60mm angular artery; 0,55mm greater palatine artery; 0,45mm infraorbital artery). Conclusions: The results presented in this article are valid tool supporting the non-invasive mapping of facial vascularization (AU)

RESUMO

La reparación de las heridas vasculares en las contiendas bélicas se inicia en la Segunda Guerra Mundial (1939-1945) y se lleva a cabo con regularidad en la Guerra de Vietnan (1959-1975). En la Guerra Civil Española (1936-1939) las suturas directas fueron poco frecuentes y en la mayoría de los casos se procedió a la ligadura del vaso, alejada de la lesión. El objetivo de éste estudio es analizar la actitud terapéutica ante las lesiones vasculares en el VIII Cuerpo del Ejército en la Guerra Civil Española, ya que sus buenos resultados dieron lugar a la creación de un Servicio Específico para el tratamiento de éste tipo de lesiones cronificadas en el Hospital Militar de San Cayetano en Santiago de Compostela. Con éste fin se analizaron los manuales y protocolos de tratamiento por los que se regían los cirujanos militares del Ejército del Norte. Se comentan dichos procederes y la importancia de la habilidad quirúrgica en la técnica de ligadura vascular que es la que da lugar a los buenos resultados obtenidos


The repair of the vascular lessions in the war begins in the Second World War (1939-1945) and it pratices regularity on the Vietnan War (1959-1975). On the Spanish Civil War (1936-1939) the vascular sutures were little frequent and in the vast majority of the cases ligature of the Wessel was performed. Our objetive is to value the Management of the vascular lessions in the VIII Army of the Nord in the Spanish Civil War. It Studies the protocols of treatment of military súrgenos andi t coments our therapeutics peculiaritys

RESUMO

Introducción: La proximidad del cuerno posterior del menisco externo a la arteria poplítea condiciona un riesgo de lesión vascular en su sutura. El objetivo es definir la localización de la arteria poplítea, establecer la distancia mínima del muro posterior del menisco externo a la arteria, al nervio ciático poplíteo externo (CPE) y su correlación con otras variables. Material y método: Se revisaron retrospectivamente 102 resonancias magnéticas nucleares de pacientes operados en nuestro centro. Se seleccionó el corte axial donde se identificase adecuadamente el menisco externo y se realizaron el conjunto de mediciones. Resultados: La arteria se localizó lateral a la línea media antero-posterior en el 94% de los casos. La distancia mínima media del muro posterior del menisco externo a la arteria poplítea fue de 1,01 cm. (0,32-1,74, SD: 0,304). La distancia mínima media al CPE fue de 1,74 cm. (0,75-2,87, SD: 0,374). No se encontró una correlación de la distancia del muro posterior a la arteria poplítea con la altura, el peso, el IMC, el diámetro del menisco externo ni el diámetro de la meseta tibial. Se encontró una correlación entre la distancia del muro posterior al CPE con el peso y el IMC. Conclusiones: La proximidad del muro posterior a la arteria poplítea debe ser tenida en cuenta a la hora de realizar suturas. Esta distancia está dentro de la profundidad recomendada en los dispositivos de sutura «todo-dentro» y no está en relación con la talla, el peso, el IMC, el tamaño del menisco externo ni la meseta tibial (AU)


Introduction: The proximity of the posterior horn of the lateral meniscus to the popliteal artery determines a risk of vascular injury in its suture. The aim of this study is to determine the location of the popliteal artery, and to establish the minimal distance from the posterior wall of the lateral meniscus to the artery, the common peroneal nerve (CPN), and its correlation to other variables. Material and methods: A total of 102 magnetic resonance studies were retrospectively reviewed from patients undergoing surgery at our institution. The axial section where the lateral meniscus could be clearly defined was selected, and the measurements were performed. Results: The artery lay laterally to the midline in 94% of the cases. The minimal mean distance from the posterior wall of the lateral meniscus to the popliteal artery was 1.01 cm. (0.32-1.74, SD: 0.304). The minimal mean distance to the CPN was 1.74 cm. (0.75-2.87, SD: 0.374). No association was found between the minimal mean distance from the posterior wall to the popliteal artery with the height, weight, BMI, the lateral meniscus diameter, or the tibial plateau diameter. An association was found between the distance from the posterior wall to the CPN with the weight and the BMI. Conclusions: The proximity of the posterior horn to the popliteal artery should be considered when performing sutures. This distance is within the recommended depth for all-inside meniscus repair devices. This distance is not related to height, weight, BMI, lateral meniscus nor tibial plateau diameters (AU)

RESUMO

Until recently, works on the microscopic anatomy of the human intestinal villus had been hampered by lack of in vivo observations, and were based on early corrosion cast techniques before the advent of scanning electron microscopy to correctly identify the nature of the vessels seen. On review, a large number of human anatomy and histology texts carry a possibly erroneous message, as is the same with the earlier works, that there are arterioles and venules in the core of these villi. Based on recently available high resolution in vivo observations by endoscopy, our work by transmission electron microscopy and light microscopy techniques on cross sections of the villi shows only capillary type channels, and such is also true of those anatomy and histology textbooks that have photomicrographs of cross sections of the villi (despite their possible errors). An analytical discussion in further support of our findings is made, based on established anatomical and physiological principles
