ABSTRACT

SUMMARY: Corona mortis is classified as a connection between the inferior epigastric and obturator vessels over the superior pubic ramus. Its incidence varies among different studies. The corona mortis is an extremely important anatomical variation as it can be injured in a great number of procedures. Moreover, it can also be injured during pelvic or acetabular fractures. A male cadaver fixed in a 10 % formalin solution had its pelvic region dissected and an arterial corona mortis was observed on its right side. The left hemipelvis presented no variations whatsoever. This vessel was measured with the aid of a digital caliper. We aim to report this variation and address - from an orthopedic point of view - the clinical and surgical significance of the corona mortis.


RESUMEN: La corona mortis es clasificada como una conexión entre los vasos epigástricos inferiores y obturadores sobre la rama superior del pubis. Su incidencia varía según los diferentes estudios. La corona mortis es una variación anatómica extremadamente importante, ya que se es posible dañarla en un número significativo de procedimientos. Además, también puede resultar lesionada durante las fracturas pélvicas o acetabulares. Durante la disección de un cadáver de sexo masculino fijado en solución de formalina al 10 %, se observó la corona mortis arterial en el lado derecho de la región pélvica. El lado izquierdo de la pelvis no presentó ninguna variación. Se midió la corona mortis con ayuda de un calibre digital. Nuestro objetivo fue informar sobre esta variación y abordar - desde el punto de vista ortopédico - la importancia clínica y quirúrgica de la corona mortis.

ABSTRACT

The aim of this study was to evaluate the effects of maternal protein and energy restriction during lactation, analyzing on morphological dimensions whether there was catch-up growth through normative nutrition restored, as well as on mechanical axis of femur of the offspring at adulthood. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23 % protein, 2) protein-energy restricted group (PER) - free access to an isoenergetic, protein-restricted diet containing 8 % protein, and 3) energy-restricted group (ER) ­ fed with restricted amounts of a standard laboratory diet. At weaning, all pups were separated of dams and received free access to a standard laboratory diet containing 23 % protein until 180 days, when the rats were anesthetized and sacrificed. The dimensions of excised pup femur were measured directly using pre-established anatomical points. Morphometric analysis of the femur (macroscopic) showed that most of the measurements in the ER and PER groups were significantly lower than in the control group, with the greatest reductions occurring in the PER group and several structural abnormalities. Our results show that protein and energy restriction during lactation leads to an incomplete catch-up growth in adulthood. The femur showed significant reduction in most of the parameters in the two treated groups, particularly the PER group, when compared to the control group.


El objetivo de este estudio fue evaluar los efectos de la restricción de la proteína materna y de energía durante la lactancia, y analizar las dimensiones morfológicas si hubo recuperación del crecimiento a través de la nutrición normativa restaurada, así como en el eje mecánico del fémur de la descendencia en la edad adulta. En el parto, las crías de ratas Wistar fueron agrupadas aleatoriamente en los siguientes grupos: 1) control (C) - con acceso libre a una dieta estándar del laboratorio, que contenía 23 % de proteínas; 2) con restricción de proteínas y energía (PER) - acceso libre a una dieta isoenergética, con restricción de proteínas, conteniendo un 8 % de éstas y 3) grupo con restricción de energía, alimentado con restricción en la cantidad de alimento de la dieta estándar del laboratorio (ER). Al destete, todas las crías fueron separadas y recibieron las dietas establecidas hasta los 180 días (d180), luego fueron anestesiadas y sacrificadas. Las mediciones de los fémures de las crías de rata fueron obtenidas por puntos anatómicos preestablecidos. El análisis morfométrico de fémur demostró que la mayoría de las mediciones en los grupos ER y PER eran significativamente menores que las del grupo control, con mayores reducciones en el grupo PER. Nuestros resultados muestran que las restricciones de energía y proteínas durante la lactancia conducen a una recuperación del crecimiento incompleto en la edad adulta. El fémur mostró una reducción significativa en la mayoría de los parámetros en los dos grupos tratados, en particular el grupo de PER, en comparación con el grupo control.

ABSTRACT

The superior gemellus muscle (SGM) normally arises from the outer surface of the spine of the ischium, blends with the upper part of the tendon of the obturator internus, and is inserted with it into the medial surface of the greater trochanter. In this paper, we describe an anatomical variation in which the SGM is absent bilaterally. Therefore, as there are not many cases in literature, our attention has been drawn to the importance about absence of SGM, in order to improve anatomical and clinical knowledge about this finding.


El músculo gemelo superior (SGM) que se origina de la superficie externa de la parte posterior del isquion, se une a la parte superior del tendón del músculo obturador interno, y se introduce con él en la superficie medial del trocánter mayor. En este trabajo se describe una variación anatómica en la que el SGM está ausente bilateralmente. Debido a la escaza descripción de esta variación, es relevante conocer la ausencia de la SGM, con el fin de mejorar el conocimiento anatómico y clínico de este hallazgo.

ABSTRACT

The aim of our study was to verify the prevalence of the sternal foramen in adult cadavers and dry bones, as well as to determine its exact localization and relation to acupuncture points. One hundred eighty sternums fixed and contained in 10 percent formaldehyde solution were examined, of which 100 were dry bones and 80 belonged to adult cadavers. The morphometric measures were expressed in millimeters when measuring the length: 1) from jugular incision to the foramen (JI-F); 2) from sternal angle to the foramen (EA-F); 3) from xiphoid process to the foramen (XP-F). Statistical analysis was performed to compare expected vs obtained foramina frequency, using Fisher's test (p0.05 was considered significant). The results showed 16.6 percent sternal foramina, significant higher than expected (p0.0248). Of the 30 foramina, 53.3 percent were found in cadavers, of which one was a woman, and 46.7 percent sternums were found in dry bones. Of the cadavers with sternal foramen, 10 foramina were at the 5th sternochondral articulation level and 6 foramina at the 4th sternochondral level. Of the 14 analyzed dry bones, 9 foramina were at the space between the 4th and the 5th costal pit level and 5 foramina were at the 5th costal pit level. The mean±SD (mm) total length of the sternums was 151.8+/-34 and the measures JI-F, EA-F, and XP-F were, respectively, 103.8+/-22.1mm, 65.6+/-15mm and 46.9 +/-15mm. Knowledge of this occurrence is important to avoid serious heart injury by needle insertion, especially as this area holds a commonly used acupuncture point and sternal puncture...


El objetivo del estudio fue verificar la prevalencia del foramen esternal en cadáveres adultos y huesos secos, así como, determinar su localización y su relación con los puntos de acupuntura. Fueron examinados 180 esternones fijados en solución de formol al 10 por ciento, 100 eran huesos secos y 80 pertenecían a cadáveres de individuos adultos. Las medidas morfométricas se expresaron en milímetros, efectuándose las siguientes mediciones: 1) desde la incisura yugular al foramen; 2) desde el ángulo esternal al foramen y 3) desde el proceso xifoides hasta al foramen. El análisis estadístico permitió comparar la frecuencia de los forámenes, usando el test de Fisher (p 0,05 ). Los resultados mostraron la presencia del foramen esternal en 16,6 por ciento de los casos, siendo significativamente mayor a lo esperado (p 0,0248). De los 30 forámenes, el 53,3 por ciento se encontró en cadáveres y en el 46,7 por ciento en los huesos secos. De los cadáveres con foramen esternal, 10 forámenes se encontraban a nivel de la 5 articulación esternocondral y 6 a nivel de la 4 articulación esternocondral. De los 14 forámenes de los huesos secos, 9 forámenes se encontraban entre entre el 4 y el 5 espacio intercostal y 5 se localizaban a nivel del 5 articulación. La longitud total del esternón fue 151,8 mm +/- 34 y las medidas desde la incisura yugular al foramen, desde el ángulo esternal al foramen y desde el proceso xifoides hasta al foramen fueron, 103,8 +/- 22,1 mm, 65,6 +/- 15 mm y 46,9 +/- 15 mm, respectivamente. El conocimiento de este hecho es importante para evitar la lesión cardiaca grave por la inserción de agujas, ya que esta zona tiene un punto de acupuntura de uso común en la punción esternal...

ABSTRACT

The goal of this investigation was to analyze and quantify changes of the reticular fibers in the prostatic urethra of patients with benign prostatic hyperplasia (BPH) and compare with a control group. Prostatic urethra tissue samples were obtained from ten patients (age range 65 to 79 years, mean 66) with clinical symptoms of bladder outlet obstruction who had undergone open prostatectomy. The ten control group samples (urethral tissue samples from the transitional zone) were collected from prostates obtained during autopsy of accidental death adults of less than 25 years. The Vv of the reticular fibers was determined with stereologic methods from 25 random fields per sample using the point-count method with a M-42 grid test system. The quantitative data were analyzed using the Kolmogorov-Smirnov and Mann-Whitney U tests. The Vv (mean+/-SD) in the control and BPH groups respectively were: 23.4+/- 1.8 and 30.3 +/- 1.2 (0.001). BPH cause significant increase of reticular fibers in prostatic urethra...


El objetivo de esta investigación fue analizar y cuantificar los cambios de las fibras reticulares en la uretra prostática de pacientes con hiperplasia prostática benigna (HPB) y compararlo con un grupo control. Muestras de tejido de uretra prostática se obtuvieron de diez pacientes (rango de edad 65 a 79 años, media 66) con síntomas clínicos de obstrucción del tracto urinario inferior que se habían sometido a prostatectomía abierta. Las diez muestras del grupo de control (muestras uretrales de tejido de la zona de transición) se obtuvieron de próstatas durante la autopsia de sujetos adultos con muerte accidental menores de 25 años. El Vv de las fibras reticulares se determinó con métodos estereológicos de 25 campos al azar por muestra utilizando el método de valor de conteo con el sistema M-42. Los datos cuantitativos se analizaron mediante la prueba de Kolmogorov-Smirnov y Mann-Whitney U. El Vv (media +/- DE) en el grupo control y BPH, respectivamente, fueron: 23,4 +/- 1,8 y 30,3 +/- 1,2 (0,001). La BPH causó aumento significativo de fibras reticulares en uretra prostática...

ABSTRACT

Anatomical variations in the formation of the sural nerve are common, although the topographical localization of this nerve is constant. In this report, we describe the histological analysis of anomalous course of the medial sural cutaneous nerve which descended through the gastrocnemius via a tunnel formed within the muscle and fascia. This anatomical curiosity are clinically important when evaluating sensory axonal loss in distal axonal neuropathies since sural nerve mononeuropathy is less likely to occur.


Las variaciones anatómicas en la formación del nervio sural son comunes, aunque la localización topográfica de este nervio es constante. En este reporte se describe el análisis histológico del nervio cutáneo sural medial de curso anómalo, que descendió a través de los músculos gastrognemios en un túnel formado en el músculo y la fascia. Esta curiosidad anatómica es de importancia clínica cuando se evalúa la pérdida sensitiva distal en neuropatías axonales, desde mononeuropatía del nervio sural a otras de menor frecuencia.

ABSTRACT

The aim of this study was to evaluate the effects of maternal protein and energy restriction during lactation on mandible dimensions of pups (female) at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23 percent protein, 2) protein-energy restricted group (PER) - free access to an isoenergetic, protein-restricted diet containing 8 percent protein, and 3) energy-restricted group (ER) ­ fed with restricted amounts of a standard laboratory diet. At weaning (d21), all pups were separated of dams and received free access to a standard laboratory diet containing 23 percent protein until 90 days (d90), when the rats were anesthetized and sacrificed. The dimensions of excised pup mandible were measured directly using pre-established 3 anatomical points. Morphometric analysis showed that most of the measurements in the ER and PER groups were significantly lower than in the control group, with the greatest reductions occurring in the PER group. These results show that protein and energy restriction during lactation have an important influence on pup mandible development and continue through the aging process.


El objetivo de este estudio fue evaluar los efectos de la restricción de la proteína materna y de la energía durante la lactancia sobre las dimensiones de la mandíbula de crías (hembras) durante la vida. En el parto, las crías de ratas Wistar fueron agrupadas aleatoriamente en los siguientes grupos: 1) control (C) - con acceso libre a una dieta estándar del laboratorio, que contenía 23 por ciento de proteínas; 2) con restriccion de proteínas y energía (PER) - acceso libre a una dieta isoenergética, con restricción de proteínas, conteniendo un 8 por ciento de éstas y 3) grupo con restricción de energía, alimentado con restricción en la cantidad de alimento de la dieta estándar del laboratorio (ER). Al destete, todas las crías fueron separadas y recibieron las dietas establecidas hasta los 90 días (d90), luego fueron anestesiadas y sacrificadas. Las mediciones de las mandíbulas de las crías de rata fueron obtenidas por 3 puntos anatómicos preestablecidos. El análisis morfométrico de la mandíbula demostró que la mayoría de las mediciones en los grupos ER y PER eran significativamente menores que las del grupo control, con mayores reducciones en el grupo PER. Estos resultados muestran que las restricciones de energía y proteínas durante la lactancia tienen una influencia importante en el desarrollo de la mandíbula de las crías, las que se mantuvieron con el paso del tiempo.

ABSTRACT

Rabbits have been used as an experimental model in many diseases and for the study of toxicology, pharmacology and surgery in many universities. However, some aspects of their macro anatomy need a more detailed description, especially the abdominal and pelvic arterial vascular system, which has a huge variability in distribution and trajectory. Thirty cadaveric adult New Zealand rabbits, 13 male and 17 female, with an average weight and rostrum-sacral length of 2.5 kg and 40cm, respectively, were used. The thoracic aorta was cannulated and the vascular system was filled with stained latex S-65. The celiac artery and its proximal branches were dissected and lengthened in order to evidence origin and proximal ramifications. The celiac artery emerged between the 12th and 13th thoracic vertebra in 11 (36.7 percent) rabbits; at the level of the 13th thoracic vertebra in 6 (20 percent) rabbits; between the 13th thoracic vertebra and the 1st lumbar vertebra in 12 (40 percent) rabbits; and at the level of the 1st lumbar vertebra in only one (3.3 percent) rabbit. The mean length of the celiac artery was 0.5cm. The celiac artery first branch was the lienal artery, the second branch was the left gastric artery and the hepatic artery arose from the left gastric artery in all the dissected rabbits. No relation was observed between the celiac artery length and the rostrum-sacral length in rabbits. The number of left gastric and lienal artery branches and the distribution of celiac artery origin are not gender dependent.


Os coelhos têm sido usados como modelo experimental em diferentes patologias e para estudos de toxicologia, farmacologia e cirurgia em várias universidades. Entretanto apesar de sua grande utilização, muitos aspectos de sua macroanatomia, em especial os que se referem ao sistema vascular arterial que irrigam as viscerais abdomino-pélvicas ainda carecem de uma descrição mais detalhada, pois os vasos arteriais apresentam grande variabilidade na sua distribuição e trajeto. Foram utilizados 30 coelhos, 13 machos e 17 fêmeas, pesando em media 2,5 kg e apresentando comprimento rostro-sacral em torno de 40cm. A artéria aorta torácica foi canulada e através da mesma foi feita à fixação com solução de formaldeído a 10 por cento e repleções vasculares com solução de Petrolátex S65 corado. A artéria celíaca e suas ramificações proximais foram dissecadas ao longo do seu percurso, registrando com auxílio de um paquímetro seu comprimento e sua esqueletopia. A artéria celíaca teve sua emergência de forma única diretamente da artéria aorta abdominal em todos os animais dissecados. Emitiu inicialmente a artéria lienal e a seguir a artéria gástrica esquerda que se continuou como hepática em todos os 30 animais. A artéria celíaca teve sua origem entre a 12ªe 13ª vértebra torácica em 11 animais (36,7 por cento), na 13ª vértebra torácica em 6 (20 por cento), entre a 13ª vértebra torácica e a 1ª vértebra lombar em 12 (40 por cento) e na 1ª vértebra lombar em apenas 1 animal (3,3 por cento). O comprimento médio da artéria celíaca foi de 0,5cm. Não foi observada relação entre o comprimento da artéria celíaca e o comprimento rostro-sacral dos coelhos. O número de artérias gástricas esquerdas, ramificações principais da artéria lienal, bem como a origem da artéria celíaca independeram do sexo do animal.

ABSTRACT

The purpose of this study was to evaluate the effects of maternal protein and energy restriction during lactation on the body weight and tibiae dimensions of pups at aging. At parturition, Wistar rat dams were randomly assigned to the following groups: 1) control group (C) - free access to a standard laboratory diet containing 23% protein, 2) protein-energy restricted group (PR) - free access to an isoenergetic, protein-restricted diet containing 8% protein, and 3) energy-restricted group (ER) - fed restricted amounts of a standard laboratory diet. At weaning, all pups were separated of dams and received free access to a standard laboratory diet containing 23% protein until 180 days when the rats were anesthetized and sacrificed. The dimensions of excised pup tibia were measured directly using pre-established anatomical points. Morphometrical analysis of the tibia showed that most of the measurements in the ER and PR groups were significantly lower than in the control group, with the greatest reductions occurring in the PR group. These results show that protein and energy restriction during lactation have an important influence on pup tibia development.


Los objetivos de este estudio fueron evaluar los efectos de la restricción materna de proteínas y de energía durante la lactancia y sus efectos en el peso corporal y las dimensiones de las tibias de crías en ratas. En el parto, las crías de ratas Wistar fueron agrupadas aleatoriamente en los grupos siguientes: 1) grupo control (C) - con acceso libre a una dieta estándar del laboratorio, que contenía 23% de proteínas; 2) grupo con restricción de proteínas y energía (PR) - acceso libre a una dieta isoenergética, con restricción de proteínas, conteniendo un 8% de éstas y 3) grupo con restricción de energía, alimentado con restricción en la cantidad de alimento de la dieta estándar del laboratorio (ER). Al destete, todas las crías fueron separadas y recibieron la dieta estándar del laboratorio, conteniendo 23% de proteínas, hasta los 180 días, cuando fueron anestesiadas y sacrificadas. El análisis morfométrico de la tibia demostró que la mayoría de las mediciones en los grupos ER y PR, fueron significativamente menores que las del grupo control, con mayores reducciones en el grupo PR. Estos resultados muestran que las restricciones de energía y proteínas durante la lactancia tienen una influencia importante en el desarrollo de la tibia de las crías.

ABSTRACT

OBJECTIVE: To study the incidence of testicular and epididymal appendages in patients with cryptorchidism. MATERIALS AND METHODS: We studied 65 patients with cryptorchidism, totalizing 83 testes and 40 patients who had prostate adenocarcinoma and hydrocele (control group), totalizing 55 testes. The following situations were analyzed: I) absence of testicular and epididymal appendages, II) presence of testicular appendage only, III) presence of epididymal appendage, IV) presence of testicular and epididymal appendage, V) presence of 2 epididymal appendages and 1 testicular appendage and VI) presence of paradidymis or vas aberrans of Haller. RESULTS: In patients with cryptorchidism we found testicular appendages in 23 cases (41.8 percent), epididymal appendages in 9 (16.3 percent), testicular and epididymal appendage in 8 (14.5 percent), 2 epididymal appendages and 1 testicular in 1 (1.8 percent) and absence of appendages in 14 (25.4 percent). In the control group, we found testicular appendages in 29 (34.9 percent), epididymal appendages in 19 (22.8 percent), testicular and epididymal appendage in 7 (8.4 percent), and absence of appendages in 28 (33.7 percent), we did not find 2 epididymal appendages in this group, and none of the patients in the 2 groups presented paradidymis or vas aberrans of Haller. CONCLUSION: The occurrence of testicular and epididymal appendages is quite variable. There was no statistically significant difference in the incidence and distribution of the testicular and epididymal appendages between patients with cryptorchidism and those from the control group.
