The accuracy of internal organ volume estimation done with ultrasound (US) was found to be multifactorial. Hence, we aimed to describe and validate the volume assessment of ultrasound and standard volume estimation formulae for different shaped intra-abdominal organs using spleens and kidneys.Dissected cadaveric kidneys (n=25) and spleens (n=29) were scanned to obtain linear measurements and ultrasound auto-generated volumes (USV). Linear measurements were used to calculate the volumes manually with ellipsoid, prolate, and Lambert volume estimating formulae. The actual volumes (AV) of organs were obtained by the water displacement method. Volume assessment accuracy of USV and different formulae were compared by comparing bias, precision and Bland-Altman plot analysis. The US linear and volume measurement procedure was reliable with high inter and intra-observer agreements (linear: Chronbach's α=0.983 to 0.934; volumes: Chronbach's α=0.989). USV estimates were accurate with a high correlation to AV and low estimation bias (-5.9%). Also, prolate (bias=-0.75%) and ellipsoid formulae (bias=-3.75%) were reliable with a negligible bias in estimated volumes. Contrary, the Lambert formula was unreliable due to a high bias (41.6%). For all evaluated methods, the estimation error found to be related to the organ size (T=3.483; p=0.001), mainly when the assessed organ is larger than 50 ml. Also, the shape related estimation error found to be related to the volume estimation formula used.This study has validated the USV for kidney and splenic volume assessments while describing volume-calculating formula employed, organ size and shape as significant contributors for volume estimation accuracy.

Se encontró que la precisión de la estimación del volumen de órganos internos realizada con ultrasonido (US) es multifactorial. El objetivo fue describir y validar la evaluación de volumen mediante ecografía y las fórmulas estándar de estimación de volumen para órganos intraabdominales de diferentes formas utilizando bazos y riñones.Se evaluaron riñones cadavéricos disecados (n = 25) y bazos (n = 29) para obtener medidas lineales y volúmenes autogenerados por ultrasonido (USV). Se utilizaron medidas lineales para calcular los volúmenes manualmente con fórmulas de estimación de volumen elipsoide, prolate y Lambert. Los volúmenes reales (AV) de los órganos se obtuvieron mediante el método de desplazamiento de agua. Se comparó la precisión de la evaluación del volumen de USV y diferentes fórmulas comparando el sesgo, la precisión y el análisis de la gráfica de Bland-Altman. El procedimiento de medición lineal y de volumen mediante US fue confiable con alta concordancia inter e intraobservadores (lineal: α de Chronbach = 0,983 a 0,934; volúmenes: α de Chronbach = 0,989). Las estimaciones de USV fueron precisas con una alta correlación con AV y un bajo sesgo de estimación (-5,9%). Además, las fórmulas prolate (sesgo= -0,75%) y elipsoide (sesgo = -3,75%) fueron confiables con un sesgo insignificante en los volúmenes estimados. Por el contrario, la fórmula de Lambert no fue confiable debido a un alto sesgo (41,6%). Para todos los métodos evaluados, se encontró que el error de estimación estaba relacionado con el tamaño del órgano (T = 3.483; p = 0.001), principalmente cuando el órgano evaluado es mayor de 50 ml. Además, se encontró que el error de estimación de forma está relacionado con la fórmula de estimación de volumen utilizada.Este estudio ha validado el USV para evaluaciones de volumen renal y esplénico al mismo tiempo que describe la fórmula de cálculo de volumen empleada, el tamaño y la forma de los órganos como contribuyentes significativos de la precisión de la estimación de volumen.

The aim of this study was to investigate the occurrence of diseases in free-ranging wild canids that were roadkill on highways in the State of Espírito Santo, Brazil. PCR tests were performed for the detection of Brucella sp., Babesia sp., Rangelia sp., and Hepatozoon sp. in the spleen. Morphological evaluation and identification of parasites was performed in the liver and lung. Twenty specimens of C. thous were necropsied at the Animal Pathology Sector of the Veterinary Hospital of the Universidade Federal do Espírito Santo. Tissue samples were processed for histopathological examination and polymerase chain reaction (PCR) analysis. There was no PCR amplification of genomic DNA sequences of Brucella sp., Babesia sp., Rangelia sp., and Hepatozoon sp. using DNA extracted from the spleen as template. Histologically, lesions associated with parasitism by Platynosomum sp. and Angiostrongylus sp. were observed in the liver and lung, respectively. This is the first report of Platynosomum sp. and Angiostrongylus sp. parasitism in C. thous in the state of Espírito Santo, Brazil. Therefore, this study demonstrated parasitism of crab-eating foxes by Platynosomum sp. and Angiostrongylus sp. Importantly, no evidence of infection with Brucella sp., Babesia sp., Rangelia sp., and Hepatozoon sp. was obtained by PCR analysis.(AU)

Child Compound Endothelium Corneum(CCEC)has the effects in invigorating the spleen and appetizing the appetite, and dissolving the accumulation of food. The recent studies have proved that it could improve gastrointestinal motility, restore physiological gastrointestinal peristalsis, increase gastrointestinal digestive motility, and enhance appetite. This trial aimed to evaluate its clinical efficacy and safety in the treatment of children's anorexia(spleen-stomach disharmony). A total of 240 children with anorexia in line with the inclusion and exclusion criteria were selected and randomly divided into experimental group and control group, with 120 in each group. Patients in the experimental group took CCEC and Erpixing Granules simulant. Patients in the control group took Erpi-xing Granules and CCEC simulant. After 21 days of treatment, there was no statistical difference in the recovery rate of anorexia, reduced food intake, eating time, weight change, traditional Chinese medicine syndrome effect, single symptom effect, and trace element Zn recovery rate between the two groups. Based on the non-inferiority test, the experimental group was not inferior to the control group in efficacy. How-ever, the effect of CCEC in reducing appetite in children with anorexia was better than that of control drugs(P<0.05). There was no statistical difference in the incidence of adverse events and adverse reactions between the two groups during the trial. This experiment confirmed the efficacy and safety of CCEC in the treatment of children's anorexia(spleen-stomach disharmony), with a safety and re-liability in clinical application. In addition, it was a better choice for children with anorexia who were mainly manifested by reduced appetite. Meanwhile, compared with granule, chewable tablets were more convenient to take in clinic. Therefore, the efficacy and safety of CCEC for the treatment of children's anorexia(spleen-stomach disharmony) were not inferior to those of Erpixing Granules, with a safety and reliability in clnic. However, due to the small sample size of this trial, the efficacy results only show a trend. It is suggested to further carry out a large-sample-size clinical study to define the clinical advantages of CCEC.

ABSTRACT The spleen is one of the most frequently affected organs in blunt abdominal trauma. Since Upadhyaya, the treatment of splenic trauma has undergone important changes. Currently, the consensus is that every splenic trauma presenting with hemodynamic stability should be initially treated nonoperatively, provided that the hospital has adequate structure and the patient does not present other conditions that indicate abdominal exploration. However, several topics regarding the nonoperative management (NOM) of splenic trauma are still controversial. Splenic angioembolization is a very useful tool for NOM, but there is no consensus on its precise indications. There is no definition in the literature as to how NOM should be conducted, neither about the periodicity of hematimetric control, the transfusion threshold that defines NOM failure, when to start venous thromboembolism prophylaxis, the need for control imaging, the duration of bed rest, and when it is safe to discharge the patient. The aim of this review is to make a critical analysis of the most recent literature on this topic, exposing the state of the art in the NOM of splenic trauma.

RESUMO O baço é um dos órgãos mais frequentemente afetados no trauma abdominal contuso. Desde os trabalhos de Upadhyaya, o tratamento do trauma esplênico vem sofrendo importantes modificações. Atualmente, é consenso que todo trauma esplênico que se apresenta com estabilidade hemodinâmica pode ser tratado inicialmente de forma não operatória, desde que o serviço possua estrutura adequada e o paciente não apresente outras condições que indiquem exploração da cavidade abdominal. Entretanto, vários tópicos permanecem controversos no que diz respeito ao tratamento não operatório (TNO) do trauma esplênico. A angioembolização esplênica é uma ferramenta de grande auxílio no TNO, porém não há consenso sobre suas indicações precisas. Não há uma definição na literatura a respeito da forma como o TNO deve ser conduzido, tampouco a respeito da periodicidade do controle hematimétrico, do limiar de transfusão que define falha do TNO, de quando iniciar a profilaxia contra tromboembolismo venoso, da necessidade de exames de imagem de controle, do período de repouso no leito, e de quando é seguro indicar alta hospitalar. O objetivo desta revisão é analisar de forma crítica a literatura a respeito desse tema, expondo o estado da arte no TNO do trauma esplênico.

OBJECTIVE@#To investigate the therapeutic effect of spleen low molecular weight extracts on epileptics hydrochloride-induced leukopenia in mice and explore its mechanism.@*METHODS@#The model of leukopenia in mice was established by the injection of epirubicin hydrochloride (10 mg/kg). After the injection of chemotherapeutic drugs, leukocytopenia mice were treated with different doses of spleen low molecular weight extract, Ganoderma oral solution and recombinant granulocyte colony stimulating factor (rhG-CSF). The general survival status indicators such as body weight, coat color and athletic ability of mice in each group were recorded; the tail vein blood of mice in each group was collected and the white blood cell count in them was calculated; bone marrow of mice was taken and bone marrow smears were observed.@*RESULTS@#In the model group, the weight of the mice gradually decreased in the later period, their coat became dark and rough, and the ability to exercise decreased, while the mice in the treatment groups showed different degrees of improvement in their survival status except for the mice treated by rhG-CSF. There was no significant fluctuation in the white blood cell count of the blank control mice. After injection of epirubicin, the white blood cell count of peripheral blood in the model mice and treated mice were decreased. The white blood cell count was lower in the mice treated with high-dose low molecular weight extract and rhG-CSF than that in other experimental groups. Bone marrow smear showed that the proportion of bone marrow nucleated cells in the mice treated with the low molecular weight extract of the spleen was significantly higher than that of model mice (P<0.05).@*CONCLUSION@#The low molecular weight spleen extracts can significantly improve the hematopoietic state of mouse bone marrow, promote the proliferation of inhibited bone marrow cells, and thus has the effect of treating leukopenia in mice.

Resumen Introducción: El infarto esplénico ocurre cuando la arteria esplénica o alguna de sus ramas quedan ocluidas, ya sea por émbolos distantes o por trombosis in situ. Dentro de la literatura mundial hay muy pocos casos documentados de infarto esplénico asociado a infección por Citomegalovirus, por lo que este podría considerarse el primero en Colombia. Presentación del Caso: Se trata de una paciente femenina de 53 años quien fue atendida en una institución de tercer nivel de la Ciudad de Bogotá, Colombia, por cuadro de dolor abdominal, a quien se le realizó una tomografía abdominal contrastada que demostró en el bazo una lesión hipodensa en cuña correspondiente con infarto esplénico por lo cual se realizaron estudios complementarios evidenciando como único dato positivo la positividad de la IgM para Citomegalovirus, descartándose eventos de h ipercoagulabilidad. Discusión: El infarto esplénico es una condición infrecuente que normalmente se presenta con síntomas variables e inespecíficos, dentro de las enfermedades infecciosas que corresponden con aproximadamente el 30% de los diagnósticos de Infarto esplénico, la infección por Citomegalovirus únicamente ha sido reportada en muy pocos casos. Se presenta el caso de una mujer joven con infarto esplénico como diagnóstico final de dolor abdominal en quien se descartaron causas de hipercoagulabilidad y se confirma la infección aguda por Citomegalovirus, lo cual se ha descrito muy poco en la literatura y puede considerarse el primer caso reportado en Colombia.

Abstract Introduction: Splenic infarction occurs when the splenic artery or any of its branches are occluded, either by distant emboli or by thrombosis in situ. Within the world literature, there are very few documented cases of splenic infarction associated with Cytomegalovirus infection, so this could be considered the first in Colombia. Case Presentation: This is a 53-year-old female patient who was treated at a third-level institution in the City of Bogotá, Colombia, for symptoms of abdominal pain, who underwent a contrasted abdominal tomography that she demonstrated in the spleen. a hypodense wedge lesion corresponding to splenic infarction, for which reason complementary studies were carried out, showing the positivity of IgM for Cytomegalovirus as the only positive data, ruling out events of hypercoagulability. Discussion: Splenic infarction is an infrequent condition that normally presents with variable and nonspecific symptoms. Among infectious diseases that correspond to approximately 30% of the diagnoses of splenic infarction, Cytomegalovirus infection has only been reported in very few cases. The case of a young woman with splenic infarction is presented as the final diagnosis of abdominal pain in whom causes of hypercoagulability were ruled out and acute infection by Cytomegalovirus was confirmed, which has been described very little in the literature and can be considered the first reported case In colombia.

ABSTRACT BACKGROUND: There are quite a few studies examining prognostic factors in non-traumatic splenectomies compared to traumatic ones. OBJECTIVE: This study aimed to evaluate the predictors of mortality in patients who underwent splenectomy for non-traumatic spleen diseases. METHODS: Medical records of the patients, who had undergone total splenectomy for non-traumatic spleen diseases at a tertiary center between January 2009 and December 2019, were retrospectively reviewed. Exclusion criteria included patients younger than 18 years of age, partial splenectomies, splenectomies applied to facilitate surgery for malignancy on contiguous organs, and splenectomies performed during liver transplantation. Iatrogenic splenic injuries were regarded as trauma and these cases were also excluded. RESULTS: The current study included 98 patients. Nine (9.2%) patients died. In univariate analysis, age, the presence of hematological neoplasia, hematocrit, hemoglobin, white blood cell counts, neutrophil-to-lymphocyte ratio, indications for splenectomy, application of emergency surgery, surgical technique, and transfusion of blood components were all significantly associated with mortality. In multivariate analysis, the presence of hematological malignancy [P=0.072; OR=7.17; (CI: 0.386-61.56)], the application of emergency surgery [P=0.035; OR=8.33; (CI: 1.165-59.595)] and leukocytosis [P=0.057; OR=1.136; (CI: 0.996-1.296)] were found to be positively associated with mortality. CONCLUSION: Hematologic neoplasia, emergency surgery, and leukocytosis were the independent predictors of mortality in patients, who were operated on for non-traumatic spleen diseases. A thorough preoperative evaluation, early therapeutic intervention, and advanced surgical techniques are important and can serve to minimize complications and mortality in case of inevitable splenectomy. Immunological research can provide new therapeutic opportunities that may impact positively on patients by minimizing morbidity and mortality.

RESUMO CONTEXTO: Há alguns estudos que examinam fatores prognósticos em esplenectomias não traumáticas em comparação com os traumáticos. OBJETIVO: Este estudo teve como objetivo avaliar os preditores de mortalidade em pacientes submetidos à esplenectomia para doenças do baço não traumático. MÉTODOS: Os prontuários dos pacientes, submetidos à esplenectomia total não traumática para doenças do baço em um centro terciário entre janeiro de 2009 e dezembro de 2019, foram revisados retrospectivamente. Os critérios de exclusão incluíram pacientes menores de 18 anos, esplenectomias parciais, esplenectomias aplicadas para facilitar a cirurgia para a malignidade em órgãos contíguos e esplenectomias realizadas durante o transplante hepático. As lesões esplênicas iatrogênicas foram consideradas trauma e esses casos também foram excluídos. RESULTADOS: O presente estudo incluiu 98 pacientes. Nove (9,2%) pacientes morreram. Na análise univariada, idade, presença de neoplasia hematológica, hematócrito, hemoglobina, contagem de glóbulos brancos, razão entre neutrófilos-linfócitos, indicações de esplenectomia, aplicação de cirurgia de emergência, técnica cirúrgica e transfusão de componentes sanguíneos foram significativamente associadas à mortalidade. Na análise multivariada, a presença de malignidade hematológica [P=0,072; OR=7,17; (IC: 0,386-61,56)], aplicação de cirurgia de emergência [P=0,035; OR=8,33; (IC: 1,165-59,595)] e leucocitose [P=0,057; OR=1,136; (IC: 0,996-1,296)] verificou-se que estão positivamente associados à mortalidade. CONCLUSÃO: Neoplasia hematológica, cirurgia de emergência e leucocitose foram os preditores independentes da mortalidade em pacientes, operados por doenças não traumáticas do baço. Uma avaliação pré-operatória minuciosa, intervenção terapêutica precoce e técnicas cirúrgicas avançadas são importantes e podem servir para minimizar complicações e mortalidade em caso de inevitável esplenectomia. Pesquisas imunológicas podem fornecer novas oportunidades terapêuticas que podem impactar positivamente nos pacientes, minimizando a morbidade e a mortalidade.

RESUMEN: La neoplasia quística mucinosa del páncreas (NQMP) es un tumor infrecuente, que afecta predominantemente a mujeres (90-95 %), afectando especialmente entre la quinta y séptima década de la vida; cuyo descubrimiento suele ser incidental. Por lo general, son lesiones solitarias, sin compromiso del conducto pancreático principal; poco sintomáticas y asociadas a malignidad (10 % a 40 %). El objetivo de este manuscrito fue reportar un caso de neoplasia quística mucinosa gigante del páncreas intervenida quirúrgicamente y revisar la evidencia existente respecto de sus características morfológicas, terapéuticas y pronósticas. Mujer de 29 años, con masa abdominal poco sintomática. El diagnóstico se verificó por medio de ultrasonografía, tomografía axial computarizada y resonancia nuclear magnética. Se intervino quirúrgicamente, realizándose pancreatectomía corporocaudal con preservación esplénica, sin incidentes. La paciente fue dada de alta al quinto día, sin complicaciones, y evolucionó de forma adecuada, sin complicaciones postoperatorias. La NMQP es una lesión compleja, que puede asociarse a malignidad, pero el diagnóstico preoperatorio de malignidad no puede establecerse con seguridad. El pronóstico depende de un diagnóstico precoz y un tratamiento oportuno.

SUMMARY: Mucinous cystic neoplasm of the pancreas (MCNP) are variable types of tumors, which predominantly affect women (90-95 %), and usually appear incidentally in the 5th to 7th decade of life. They are generally solitary lesions, with no involvement of the main pancreatic duct, rarely symptomatic and are associated with malignancy (10 % to 40 %). The aim of this manuscript was to report a case of giant mucinous cystic neoplasm of the pancreas surgically treated and review the existing evidence regarding its morphological, therapeutic and prognosis characteristics. Patient: A 29-year-old woman with a slightly symptomatic abdominal mass. The diagnosis was verified with ultrasound, computed axial tomography and magnetic nuclear resonance. The patient underwent surgery; an uneventful corporocaudal pancreatectomy with splenic preservation was performed. She was discharged on the fifth day, and has evolved adequately, without postoperative complications. MCNP is a complex lesion, which can be associated with malignancy, but the preoperative diagnosis of malignancy cannot be established with certainty. Its prognosis depends on early diagnosis and timely treatment.

Ingestion of metallic and/or sharp foreign bodies triggers cases of traumatic reticuloperitonitis and its sequelae in cattle. Among these sequelae, we can highlight traumatic reticulosplenitis, that has high mortality, although its frequency in the ruminant medicine is low. Therefore, based on the scarcity of information on this disease, the current study aimed to evaluate the clinical, laboratory, ultrasonographic, and pathological findings of 30 adult cattle diagnosed with traumatic reticulosplenitis. Clinical, ultrasound, and anatomopathological findings were analyzed using descriptive statistics and laboratory data were evaluated using measures of central tendency. Clinically the animals presented dehydration and alterations in behavior, appetite, and ruminal motility. Hematological findings revealed neutrophilic leukocytosis (37077.17±25004.59cell/µL) with regenerative left shift and hyperfibrinogenemia (1130±364.98mg/dL). The ultrasound examination enabled visualization of mobile and echogenic filaments that corresponded to the presence of fibrin adhesions. Displacement of the reticulum and irregularity in its contour, as well as alterations in the quantity, pattern, and amplitude of reticular contractions were also observed. Splenic alterations such as abscesses were found, characterized as circular structures of varying sizes delimited by capsules containing variable echogenicity. Splenic vein thrombosis and spleen folding were also observed. The results obtained in the current study indicated that traumatic reticulosplenitis causes nonspecific clinical signs, severe laboratory alterations and, mainly, that ultrasound is an efficient method for the diagnosis of this disease, since the anatomopathological lesions confirmed the ultrasound findings.(AU)

A ingestão de corpos estranho de origem metálica e/ou pontiagudos desencadeia em bovinos, quadros de Reticuloperitonite Traumática e suas sequelas. Dentre as quais podemos destacar a retículo esplenite traumática cuja letalidade é elevada, embora a mesma apresente uma baixa frequência na clínica de ruminantes. Portanto, baseado na escassez de informações sobre esta enfermidade, este trabalho teve por objetivo avaliar os achados clínicos, laboratoriais, ultrassonográficos e anatomopatológicos de 30 bovinos adultos diagnosticados com retículo esplenite traumática. Os achados clínicos, ultrassonográfico e anatomopatológico foram analisados por meio de estatística descritiva, e os dados laboratoriais foram avaliados utilizando-se as medidas de tendência central. Clinicamente os animais apresentaram desidratação e alterações no comportamento, apetite e na motilidade ruminal. Os achados hematológicos revelaram leucocitose (37077.17±25004.59cell/µL) por neutrofilia com desvio à esquerda regenerativo e hiperfibrinogenemia (1130±364.98mg/dL). O exame ultrassonográfico possibilitou a visualização de filamentos móveis e ecogênicos que corresponderam à presença de aderências fibrinosas, observou-se também, deslocamento do retículo e irregularidade no seu contorno além das alterações na quantidade, padrão e amplitude das contrações reticulares. Permitiu ainda, a constatação de alterações esplênicas como abscessos que foram caracterizados como estruturas circulares de variados tamanhos delimitada por capsula contendo no seu interior conteúdo de ecogenicidade variável. Trombose da veia esplênica e dobramento do baço. Os resultados obtidos nesse trabalho, indicaram que a retículo esplenite traumática causa sinais clínicos inespecíficos, severas alterações laboratoriais e principalmente que a ultrassonografia é um método eficiente para o diagnóstico dessa enfermidade uma vez que as lesões anatomopatológicas confirmaram os achados ultrassonográficos.(AU)

The study was conducted to examine the histological changes i.e. morphology and biometry of immune organs (thymus, spleen and bursa cloacalis or «Fabricius¼) of broilers in response to dietary dexamethasone (DEX). The day old chicks were obtained from the commercial hatchery and randomly divided into two groups i.e. control and experimental or treated group. The control group was reared on commercial broiler ration and the experimental group (n=25) was maintained on commercial broiler ration with corticosteroid (Dexamethasone-Decason, BP 0.5 mg, Opsonin @ 7 mg/kg feed). Samples (bursa cloacalis, spleen, and thymus) were collected from the ten control and ten experimental broilers at 14 and 28 days of experiment; then tissues were stained with Hematoxylin and Eosin. The biometric measurements of the samples were performed by the calibrated stage micrometer. Finally, the obtained data were analyzed using GraphPad Prism 8 software. In DEX treated group, the morphology of thymus, spleen and bursa cloacalis did not show any abnormal alterations. But their development rate was slower on visual inspection in DEX treated group. The length and width of bursal follicle of bursa cloacalis, thymic lobule of thymus and white pulp of spleen were statistically consisted but numerically decreased in DEX treated group than the control. The present findings suggested that DEX does not affect the histological architectures of immune organs except causing developmental arrest. Numerical decrease in the biometry of immune organs indicates that DEX causes apoptosis of immune cells in lymphoid organs of broiler.

El estudio se realizó para examinar los cambios histológicos, es decir, la morfología y la biometría de los órganos inmunes (timo, bazo y bolsa cloacal) de pollos de engorde en respuesta a la dexametasona en la dieta (DEX). Los pollitos de un día se obtuvieron de un criadero comercial y se dividieron aleatoriamente en dos grupos, control y experimental. El grupo control se crió con una ración comercial de pollos de engorde y el grupo experimental (n = 25) se mantuvo con una ración comercial de pollos de engorde con corticosteroides (DexamethasoneDecason, BP 0,5 mg, Opsonin @ 7 mg/kg). Se recogieron muestras (bolsa cloacal, bazo y timo) de los diez pollos del grupo control y diez del grupo de engorde experimental, a los 14 y 28 días de experimento. Luego, los tejidos se tiñeron con hematoxilina y eosina. Las mediciones biométricas de las muestras fueron realizadas con un micrómetro calibrado. Finalmente, los datos obtenidos se analizaron utilizando el software GraphPad Prism 8. En el grupo tratado con DEX, la morfología del timo, el bazo y la bolsa cloacal no mostraron alteraciones anormales. Pero su tasa de desarrollo fue más lenta en la inspección visual en el grupo tratado con DEX. La longitud y el ancho del folículo bursal de la bolsa cloacal, el lóbulo tímico del timo y la pulpa blanca del bazo fueron estadísticamente consistentes, pero disminuyeron numéricamente en el grupo tratado con DEX en relación al control. Los hallazgos actuales sugirieron que DEX no afecta la arquitectura histológica de los órganos inmunes, excepto que causa una detención del desarrollo. La disminución numérica en la biometría de los órganos inmunes indica que DEX provoca apoptosis de las células inmunes en los órganos linfoides de los pollos de engorde.

El bazo se localiza en el cuadrante superior izquierdo del abdomen, relacionándose posteriormente con la 9a a 11a costilla, de las que se separa por el diafragma y el receso costodiafragmático, se localiza por detrás del estómago y lateralmente al riñón izquierdo. Por alteraciones en su desarrollo pueden generarse bazos accesorios (BA), considerándose un tejido ectópico del bazo. Se consideran tejido normal, con los mismos procesos fisiológicos que el bazo principal. Con el propósito de localizar y determinar aspectos biométricos de los mismos, se realizó un estudio de corte transversal y de carácter descriptivo, sobre una muestra de 220 exámenes de TC pertenecientes a pacientes mayores de 18 años del Hospital Regional Hernán Henríquez Aravena, Temuco, Chile. Para este estudio se excluyeron toda aquellas TC con antecedentes de esplenectomía y lesiones de Bazo o peri-esplénicas. El análisis de los datos mostró una prevalencia de 32,3 % de BA, pudiendo ser de una única presencia, dos e incluso tres BA por paciente.De un total de 71 personas que tienen al menos un BA, 34 (47,89 %) fueron de sexo femenino y 37 (52,11 %) de sexo masculino. Hubo 56 pacientes (78,9 %) con un BA, 29 (40,85 %) del sexo femenino y 27 (38,03 %) del masculino; 15 (21,1 %) presentaron más de un BA, 5 (7,04 %) de sexo femenino y 10 (14,08 %) de sexo masculino, si bien se puede observar variación en la cantidad de BA según sexo, no existe una relación estadísticamente significativa entre dichas variables. La ubicación más frecuente encontrada en el plano axial fue la zona antero-medial con 59 casos (66,29 %); asimismo, en el plano sagital, la localización más frecuente fue en el polo inferior con 40 casos (44,44 %). Datos biométricos de estos BA son mostrados en Tablas. Esta información será de gran valor morfológico y médico debido a la escasa literatura existente sobre esta materia en individuos chilenos.

The spleen is located in the upper left quadrant of the abdomen, subsequently related to the 9th to 11th rib, from which it is separated by the diaphragm and the cost-diaphragmatic recess, it is located behind the stomach and laterally to the left kidney. Due to alterations in its development, accessory spleens (AS) can be generated, being considered an ectopic tissue of the spleen. The AS are considered normal tissue, with the same physiological processes as the main spleen. With the purpose of locating and determining biometric aspects of them, a cross-sectional and descriptive study was carried out on a sample of 220 CT scans belonging to patients over 18 years of age at the Hernán Henríquez Aravena Regional Hospital, Temuco, Chile. For this study, all CT scans with a history of splenectomy and spleen or peri-splenic lesions were excluded. The analysis of the data showed a prevalence of 32.3 % of AS, being able to be of a single presence, two and even three AS per patient. Of a total of 71 people who have at least one AS, 34 (47.89 %) were female and 37 (52.11 %) male. There were 56 patients (78.9 %) with a one AS, 29 (40.85 %) of the female sex and 27 (38.03 %) of the male; 15 (21.1 %) presented more than one AS, 5 (7.04 %) female and 10 (14.08 %) male, although variation in the amount of AS according to sex can be observed, no there is a statistically significant relationship between these variables. The most frequent location found in the axial plane was the anteromedial zone with 59 cases (66.29 %); also, in the sagittal plane, the most frequent location was in the lower pole with 40 cases (44.44 %). Biometric data of these AS are shown in tables. This information will be of great morphological and medical value due to the limited existing literature on this subject in Chilean individuals.

Introducción: La ruptura diafragmática es un reto diagnóstico y terapéutico para los médicos que se enfrentan al manejo de pacientes politraumatizados; debe sospecharse siempre en lesiones traumáticas de localización torácica o abdominal. Objetivo: Informar los elementos diagnósticos y terapéuticos seguidos ante ruptura diafragmática y esplénica de origen traumático. Presentación del caso: Se presenta el caso de un adolescente de 14 años que ingresa por presentar herida punzante por arma blanca de localización abdominal y manifestaciones clínicas que permiten hacer el diagnóstico de la afección tratada. Durante el acto quirúrgico se comprobó la ruptura del diafragma, hernia diafragmática y ruptura esplénica con salida de sangre hacia la cavidad abdominal. Se realizó reducción de la hernia, sutura del diafragma y extirpación del bazo por el estado del órgano en el momento de la cirugía. Conclusiones: La ruptura diafragmática postraumática es una entidad que cada vez se observa con mayor frecuencia en pacientes pediátricos. El examen clínico auxiliado por estudios imagenológicos resulta vital para su diagnóstico, tratamiento precoz y evitar complicaciones. Es importante mantener un alto índice de sospecha ante esta entidad poco frecuente, pero no rara en la edad pediátrica. El paciente tuvo una evolución favorable y fue egresado del servicio de cirugía luego de 10 días de hospitalización(AU)

Introduction: The diaphragmatic rupture is a diagnostic and a therapeutic challenge for physicians who have to face the management of polytraumatized patients; there must always be suspicion on traumatic injuries of thoracic or abdominal location. Objective: To inform the diagnostic and therapeutic elements followed in case of diaphragmatic and splenic rupture of traumatic origin. Presentation of the case: 14-year-old male teenager that was admitted for presenting stabbing wound by sharp weapon, with abdominal location and clinical manifestations that allow making the diagnosis of the condition being treated. During surgery, it was found the rupture of the diaphragm, a diaphragmatic hernia and splenic rupture with output of blood into the abdominal cavity. It was conducted the reduction of the hernia, the suture of the diaphragm and the removal of the spleen due to the state of the organ during the surgery. Conclusions: Post-traumatic diaphragmatic rupture is an entity that it is most often seen in pediatric patients. The clinical examination aided by imaging studies is vital for its diagnosis, early treatment and to avoid complications. It is important to maintain a high index of suspicion to face this rare entity, but not so rare in the pediatric age group. The patient had a favourable evolution and he was discharged of the surgery service after 10 days of hospitalization(AU)
