Effects of dietary supplementation of peanut skins (Arachis hypogaea) on performance, digestibility, and rumen fermentation of cattle: a meta-analysis.

This study aimed to estimate the magnitude of the effects of dietary inclusion of peanut skins (PS) byproduct (Arachis hypogea L.) on intake, total-tract digestibility, and rumen fermentation of cattle via meta-analysis. Data were collected following the PRISMA methodology. Nine manuscripts and a graduate thesis met the inclusion criteria from 1983 to 2010. The effect size was estimated by calculating the weighted raw mean differences (RMD) between PS vs. control diets. The RMD was compared with a robust variance estimation method followed by a meta-regression and a dose-response analysis fitting the diet characteristics like crude protein content (CP), NDF content, ether extract content (EE), tannin content, and PS level in diet (0 to 40%) as covariates. Dietary PS decreased (P < 0.01) total-tract CP digestibility (52.0 vs. 64.3%), final body weight (371.5 vs. 397.9 kg), and average daily gain (1.14 vs. 1.44 kg/day) among treatment comparisons. Likewise, PS decreased total VFA (92.6 vs. 107.6 mmol/L) and NH3-N (8.22 vs. 12.1 mg/dL), but no effects were observed on rumen pH (6.47 vs. 6.14) and VFA molar proportions. Despite the between-cluster variance, dietary PS increased the ether extract digestibility (77.5 vs. 70.2%) among treatment comparisons. The subset and dose-response analysis revealed that PS should not exceed 8% (DM basis) in the diet to prevent negative effects on CP digestibility and animal performance. In conclusion, the results of this meta-analysis do not support the dietary inclusion of PS in cattle diets beyond 8%.

Apex scavengers from different European populations converge at threatened savannah landscapes.

Over millennia, human intervention has transformed European habitats mainly through extensive livestock grazing. "Dehesas/Montados" are an Iberian savannah-like ecosystem dominated by oak-trees, bushes and grass species that are subject to agricultural and extensive livestock uses. They are a good example of how large-scale, low intensive transformations can maintain high biodiversity levels as well as socio-economic and cultural values. However, the role that these human-modified habitats can play for individuals or species living beyond their borders is unknown. Here, using a dataset of 106 adult GPS-tagged Eurasian griffon vultures (Gyps fulvus) monitored over seven years, we show how individuals breeding in western European populations from Northern, Central, and Southern Spain, and Southern France made long-range forays (LRFs) of up to 800 km to converge in the threatened Iberian "dehesas" to forage. There, extensive livestock and wild ungulates provide large amounts of carcasses, which are available to scavengers from traditional exploitations and rewilding processes. Our results highlight that maintaining Iberian "dehesas" is critical not only for local biodiversity but also for long-term conservation and the ecosystem services provided by avian scavengers across the continent.

Effects of a xylanase-rich enzyme on intake, milk production, and digestibility of dairy cows fed a diet containing a high proportion of bermudagrass silage.

We previously reported that milk production in dairy cows was increased by adding a specific xylanase-rich exogenous fibrolytic enzyme (XYL) to a total mixed ration (TMR) containing 10% bermudagrass silage (BMD). Two follow-up experiments were conducted to examine whether adding XYL would increase the performance of dairy cows consuming a TMR containing a higher (20%) proportion of BMD (Experiment 1) and to evaluate the effects of XYL on in vitro fermentation and degradability of the corn silage, BMD, and TMR (Experiment 2). In Experiment 1, 40 lactating Holstein cows in early lactation (16 multiparous and 24 primiparous; 21 ± 3 d in milk; 589 ± 73 kg of body weight) were blocked by milk yield and parity and randomly assigned to the Control and XYL treatments. The TMR contained 20% BMD, 25% corn silage, 8% wet brewer's grain, and 47% concentrate mixture in the dry matter (DM). Cows were fed the XYL-treated or untreated experimental TMR twice per day for 10 wk after a 9-d covariate period. In Experiment 2, ruminal fluid was collected from 3 cannulated lactating Holstein cows fed a diet containing 20% bermudagrass haylage, 25% corn silage and 55% concentrate. In Experiment 1, compared with Control, application of XYL did not affect DM intake (24.0 vs. 23.7 kg/d), milk yield (35.1 vs. 36.2 kg/d), fat-corrected milk yield (36.1 vs. 36.9 kg/d), or yields of milk fat (1.29 vs. 1.31 kg/d) or protein (1.07 vs. 1.08 kg/d). However, intake of neutral detergent fiber (4.67 vs. 4.41 kg/d) tended to increase with XYL; consequently, milk protein concentration was increased by XYL (3.02 vs. 2.95%). Feed efficiency tended to be lower in cows fed XYL (1.57 vs. 1.52 kg of fat-corrected milk/kg of DM intake) compared with Control. In Experiment 2, XYL tended to increase the rate of gas production in the TMR, the molar proportion of propionate for corn silage, and that of valerate for the TMR. In addition, XYL increased in vitro DM, neutral detergent fiber, and acid detergent fiber degradability of BMD and corn silage. Application of XYL to a diet with a relatively high proportion of BMD tended to increase digestible neutral detergent fiber intake, increased milk protein concentration, and in vitro degradability of DM, neutral detergent fiber, and acid detergent fiber. However, XYL did not affect milk production and tended to decrease feed efficiency in early lactation cows.

Effect of Ovar-DRA and Ovar-DRB1 genotype in small ruminants with haemonchosis.

The effect of Ovar-DRA and Ovar-DRB1 genotypes on faecal egg count (FEC) was determined in sheep and goats infected with Haemonchus contortus. One hundred and forty-three sheep from 3 different breeds (St. Croix, Katahdin and Dorper) and 150 goats from three different breeds (Spanish, Boer and Kiko) were used. Parasitological (FEC), haematological (packed cell volume) and immunological (IgA, IgG and IgM) parameters were measured. Sheep populations showed a higher FEC and humoural response than goat breeds. Genotypes were determined by high-resolution melting assays and by conventional PCR. For Ovar-DRA, sheep and goats carrying the AA genotype showed significant lower FEC than AG and GG genotypes. The additive effect was found to be 115.35 less eggs per gram of faeces for the A allele for goats. For Ovar-DRB1, only in sheep, the GC genotype was associated with low FEC. The additive effect was 316.48 less eggs per gram of faeces for the G allele, and the dominance effect was 538.70 less eggs per gram of faeces. The results indicate that single nucleotide polymorphisms within Ovar-DRA and Ovar-DRB1 could be potential markers to be used in selection programmes for improving resistance to Haemonchus contortus infection.

Cytokine and antioxidant gene profiles from peripheral blood mononuclear cells of Pelibuey lambs after Haemonchus contortus infection.

The expression profiles of cytokines and antioxidant genes were determined from an experimental infection with H. contortus in Pelibuey lambs. The infection was followed for 34 days (d) to determine the number of eggs per gram (epg) and the packed cell volume (PCV). Differential white cell counts and expression profile estimations of IL-2, IL-4, IL-5, IL-6, IL-8, IL-10, IL-13, FCεR1A, GPX and SOD1 were determined at 0 hour, 4 hours, 2 days and 14 days post-infection (PI) in infected and control groups. Comparison of the fold change between 0 and 4-hours, 4-hours and 2-days and 2- and 14-days periods was performed. Significant differences (P<.05) between epg (>2000) and PCV (>30%) were determined after 21 days and were also observed with regard to monocyte and lymphocyte cells after 2 and 7 days PI. At 0 hour and 14 days PI, the GPX and IL-2 genes showed a 0.37- and 0.49-fold decrease in expression, respectively. In contrast, upregulation was observed at 4 hours of IL-8 (2.58) and FCεR1A (2.71), at 2 days for IL-4 (2.14) and IL-8 (4.02) and at 14 days for IL-2 (0.41), IL-10 (2.35) and FCεR1A (2.28). The comparison between the intervals of infection showed high expression values against H. contortus infection in Pelibuey sheep after the 2nd period of PI involving a dichotomy T cells.

Aporte de la biología molecular en el diagnóstico de infecciones respiratorias agudas / Contribution of multiplex respiratory molecular panel to the diagnosis of acute respiratory infections

Objective: To assess the performance of multiplex-PCR for diagnosis of respiratory viruses in parallel with direct fluorescence assay (DFA). We assessed the performance and co-infection diagnosis of molecular respiratory panel PCR (MRP-PCR) and DFA in hospitalized and outpatients. Results: 8535 samples were included, 1792 tested by MRP-PCR (46.9% positive) and 6743 by DFA (35.1% positive). MRP-PCR diagnosed co-infection in 21.3% and DFA in 1.8% of the samples. Rhinovirus was the most common virus in any age group. In 210 patients both tests were done; 100 were positive by MRP-PCR and 18 by DFA. Positive concordance value was 6.2%. 85 samples were positive only by MRP-PCR and in 42 of them only novel respiratory viruses were identified. Performance of MRP-PCR was statistically significant compared DFA for traditional respiratory viruses. Discussion: Multiplex PCR has shown better sensitivity, may expand the etiologic spectrum of respiratory infections and detect a higher number of co-infections.

Objetivo: Evaluar la contribución del panel respiratorio molecular por reacción en cadena de la polimerasa-multiplex (PRM-RPC) en paralelo a la de inmunofluorescencia directa (IFD) al diagnóstico de infecciones respiratorias. Analizamos y comparamos el rendimiento y diagnóstico de co-infección de PRM-RPC con IFD en pacientes hospitalizados y ambulatorios. Resultados: Se analizaron 8535 muestras; 1792 por PRM-RPC (46,9% positivas) y 6743 por IFD (35,1% positivas). La co-infección fue 21,3% por PRM-RCP y 1,8% por IFD. El virus más frecuente fue rinovirus a toda edad. Se analizaron 210 pacientes por ambos métodos; resultaron positivas 100 por PRM-RPC y 18 por IFD, concordancia positiva de 6,2%. 85 muestras fueron solo positivas por PRM-RPC, 42 diagnosticaron nuevos virus respiratorios. El rendimiento de PRM-RPC fue significativamente mayor que el de IFD para virus respiratorios tradicionalmente diagnosticados. Conclusiones: La RCP-multiplex tiene mejor sensibilidad, podría expandir el espectro etiológico de infecciones respiratorias y detectar un mayor número de co-infecciones comparado a IFD.

Relative expression analysis of IL-5 and IL-6 genes in tropical sheep breed Pelibuey infected with Haemonchus contortus.

Haemonchus contortus is a parasitic nematode of Pelibuey sheep, a meat breed used in tropical regions. Due to anthelmintic problems, the identification of hosts resistant to H. contortus is another option of control. The aim of this study was to analyse the relative expression of IL-5 and IL-6 genes in Pelibuey sheep after H. contortus infection. Nineteen lambs infected with H. contortus and three more lambs without infection were studied. The haemonchosis was determined by the number of eggs per gram of faeces (epg) and by the estimation of the percentage of the packed cell volume (%pcv). Peripheral blood mononuclear cells (PBMCs) were obtained to extract RNA at 0, 1, 2, 7, 14, 21 and 28 days after infection to quantify the relative expression of IL-5, IL-6 and GAPDH by real-time PCR. Five lambs were classified as low responders (lr) to haemonchosis with averages of 1519 ± 315·3 epg and 31·49 ± 5·13%pcv, and 14 lambs were identified as high responders (hr) with averages of 530 ± 132 epg and 34·88 ± 3·75%pcv. The expression ratio of IL-5 was significantly different compared with control lambs at 2, 7 and 14 days post-infection (PI), and IL-6 was significantly different after 14 days. The highest level of relative expression for IL-5 and IL-6 genes was 9·9-fold and 12-fold after 2 and 14 days for hr hosts (P < 0·05) compared with control group, respectively. In conclusion, the Pelibuey breed in grazing areas exhibited different expression of IL-5 and IL-6 obtained from PBMCs against H. contortus, suggesting the importance of these cytokines in regulating the nematode infection.

Efectividad del tratamiento médico con misoprostol según dosis administrada en aborto retenido menor de 12 semanas / Effectiveness of medical treatment with misoprostol as abortion retained dose administered in less than 12 weeks

Antecedentes: El manejo terapéutico del aborto retenido consiste en evacuar la cavidad uterina espontáneamente o utilizando misoprostol previo al legrado quirúrgico. Objetivo: Evaluar la necesidad de dilatación mecánica post maduración cervical con misoprostol y la tasa de perforación uterina post legrado, utilizando diferentes dosis de misoprostol en pacientes con diagnóstico de aborto retenido menor a 12 semanas. Métodos: Se registraron datos demográficos y ginecológicos de una cohorte retrospectiva de pacientes con diagnóstico de aborto retenido menor a 12 semanas, entre enero de 2008 y diciembre de 2010. Se establecieron 3 grupos de trabajo según la dosis de misoprostol administrada vía vaginal, siendo de 100 (n=131), 200 (n=231) y 400 micrones (n=230), y se observaron las complicaciones asociadas al procedimiento. Resultados: La necesidad de dilatación mecánica fue significativamente mayor en el grupo que recibió 100 micrones de misoprostol al compararlo con el de 200 micrones y 400 micrones (p<0,01). No hubo diferencias estadísticamente significativas entre las que recibieron 200 versus 400 micrones de misoprostol. No hubo diferencias significativas respecto a perforación uterina. Conclusión: En el aborto retenido menor a 12 semanas, la necesidad de dilatación mecánica post maduración cervical, es menor si se utiliza 200 o 400 micrones de misoprostol, sin diferencias en la tasa de perforación uterina.

Background: The therapeutic management of missed abortion consists on evacuating the uterine cavity, spontaneously or by administration of misoprostol previous to curettage. Objectives: Evaluate the need of mechanical dilatation after cervical maturation with misoprostol and the rate of uterine perforation before curettage, using different doses of misoprostol in patients with diagnosis of missed abortion before 12 weeks. Methods: Demographic and gynecologic data were registered of a retrospective cohort of patients with the diagnosis of missed abortion before 12 weeks, between January 2008 and December 2010. Three groups were established according to the dose of misoprostol: 100 (n=131), 200 (n=231) and 400 microns (n=230). Complications associated to the procedure were observed. Results: The need of mechanical dilatation was significant higher for the group with 100 microns of misoprostol in comparison with 200 and 400 microns (p<0.001). There was no statistical significance among who received 200 versus 400 microns of misoprostol. No statistical significance was found for uterine perforation. Conclusion: In the missed abortion before 12 week, the need of mechanical dilatation is lower with 200 or 400 microns of misoprostol, without difference in uterine perforation rate.

Pseudoaneurisma post traumático de la arteria pedia: caso clínico / Post traumatic pseudoaneurysm of the pedal artery: case report

Pseudoaneurysm of the pedal artery is an uncommon condition that is usually caused by a traumatic injury or an iatrogenic intervention. The patient usually complains of an enlarging painless, pulsatile mass. We report a previously healthy 49 years old male presenting with a pulsatile mass of his left foot and a history of a traumatic lesion in the zone three months ago. A Doppler ultrasound examination confirmed the presence of a pseudoaneurysm of the pedal artery of 2.6 x 1.5 cm diameter. The patient underwent surgical resection of the mass and suture ligation of the artery. The postoperative period was uneventful.

Los pseudoaneurismas de la arteria pedia son infrecuentes y habitualmente se generan secundariamente a un traumatismo o a una intervención iatrogénica. Presentamos el caso de un paciente sano de 49 años que presenta un aumento de volumen pulsátil 3 meses posterior al traumatismo contuso de su pie izquierdo. En el doppler color se evidencia la presencia de un pseudoaneurisma de la arteria pedia de 2,64 x 1,53 cm. El paciente fue intervenido con resección y ligadura de la arteria con buena evolución postoperatoria.

Tratamiento endovascular de transecciones agudas de la aorta descendente / Endovascular treatment of acute traumatic aortic rupture

Background: Traumatic rupture of the thoracic aorta as a result from high-speed deceleration injury is associated with a mortality rate of 80 percent to 90 percent at the scene of the accident. Survivors usually have life-threatening injuries to other organ systems. Standard open repair is associated with a high penoperative morbidity and mortality. Endografting offers a less invasive alternative to open surgical repair. Aim: To evaluate results of endovascular management of acute traumatic descending thoracic aortic ruptures. Methods: Between August 2002 and March 2010, patients treated for this trauma were reviewed. Results: 16 patients (fourteen males mean age 42.7 +/- 15.8 years, range 24-74) underwent endovascular treatment of an acute aortic rupture. Associated traumas in fifteen patients were: severe brain (7), spleen (4), liver (1), kidney (3) and large bone (9) injuries. Motor vehicle accidents caused 13 of the injuries and fall from height 3. Rupture was diagnosed with admission CT sean and confirmed by intraoperative angiogram. Patients were treated with thoracic aortic endograft, in 11 cases the left subclavian artery was covered with no need for further revascularization. Technical success was 100 percent, no procedure-related mortality or paraplegia was observed. One patient died 5 days after the procedure due to severe associated injuries. During a mean follow-up of 30.8 months (range 1-80), no deaths, complications or need for further interventions presented. Conclusion: Endovascular treatment of acute traumatic aortic isthmic rupture is encouraging and compares favorably to open surgical approach with low morbidity and mortality rates.

Los accidentes por desaceleración súbita se asocian a transección de la aorta torácica, falleciendo 85-90 por ciento de ellos en el sitio del suceso. Los que sobreviven presentan habitualmente politraumatismo asociado grave, teniendo la reparación quirúrgica convencional de la aorta una alta morbimortalidad. La reparación endovascular es una alternativa menos invasiva y de menor morbi-mortalidad. Objetivo: Analizar los resultados de la reparación endovascular de transecciones agudas de la aorta torácica. Pacientes y Métodos: Se revisan los antecedentes de los pacientes tratados entre agosto de 2002 y marzo de 2010. Resultados: Tratamos 16 pacientes (14 hombres, 42,7 +/- 15,8 años, extremos 24-74) con transección traumática aguda de aorta torácica descendente. Quince presentaban lesiones asociadas: traumatismo encéfalo-craneano (7), fractura de huesos largos (9), laceración esplénica (4), hepática (1), renal (3). La causa del accidente fue vehicular en 13 casos y caída de altura en 3. El diagnóstico fue realizado mediante tomograña axial computada al ingreso y luego angiograña en la sala de operaciones. El tratamiento consistió en la cobertura de la zona de transección mediante el implante de una endoprótesis, siendo necesario cubrir la arteria subclavia izquierda en 11 casos, sin requerir revascularización de la extremidad. El éxito técnico fue 100 por ciento, no hubo mortalidad relacionada al procedimiento. No hubo paraplejia. Un paciente de 60 años fallece al 5to día por lesiones asociadas graves. En el seguimiento alejado a 30,8 meses (1-80) no ha habido complicaciones ni reintervenciones. Conclusión: La cirugía endovascular es una alternativa eficaz y con baja morbimortalidad para el tratamiento de transecciones de la aorta torácica.

Trauma arterial de extremidades: resultados del manejo por el cirujano no especialista / Arterial trauma of the extremities: results of the non-specialist surgeon management

El trauma arterial de extremidades (TAE) es una condición grave, con alta morbilidad que es dependiente de un oportuno diagnóstico y adecuado tratamiento. El objetivo de este trabajo es analizar los resultados del manejo del TAE por el cirujano no especialista. Se trata del análisis retrospectivo de 52 TAE operados en el Hospital del Trabajador de Santiago (1991-2000). Evaluación de la localización, mecanismo, métodos diagnósticos y técnicas de reparación. Comparación entre trauma cerrado y trauma penetrante y entre lesión de extremidad superior e interior. Análisis estadístico con test de Fisher, considerando significativa p<0,05. Son 45 pacientes, edad x 33,1 ñ 10,1 años. Hombres el 97,8 por ciento. Lesión de extremidad superior (ES) 26 casos, cerrada en 12 (TC) y penetrante en 14 (TP). En 19 la lesión fue de extremidad inferior (EI), cerrada en 14. Se empleó angiografía en el 53,3 por ciento. 35/45 pacientes (77,7 por ciento) hubo lesiones asociadas, 92,3 por ciento en TC (p<0,05). El 80 por ciento se operó antes de 6 horas. La interposición venosa fue la principal forma de reparación (54 por ciento) más el TC que en TP (p<0,05). Anastomosis primaria o arteriorrafia en el 26,0 por ciento. Se realizó fasciotomía en el 3,8 por ciento. ES y 52,6 por ciento EI (p<0,05). Seis pacientes se reoperaron. Cuatro resultaron en amputación, sólo tres por causa vascular (6,7 por ciento). Las secuelas esqueléticas y neurológicas fueron frecuentes (46,31 por ciento), mayor en TC (p<0,05). No hubo mortalidad. Se confirma la mayor gravedad del TC y se concluye que el TAE puede ser tratado satisfactoriamente por el cirujano general

¿Es seguro el manejo no operatorio de los traumatismos cerrados de hígado y bazo en adultos? / Is it safe the non-surgical management of liver and spleen closed trauma?

Se analiza la evolución clínica de 37 pacientes adultos con un traumatismo cerrado del hígado y de bazo que fueron manejados en forma no-operatoria (1991-2000). Los pacientes 81 por ciento hombres, edad promedio 34 años, fueron admitidos en urgencia hemodinámicamente estables y se les practicó una Tomografía Axial del abdomen. Se diagnosticaron 22 traumatismos del hígado y 15 del bazo. Sobre el 90 por ciento tenía lesiones asociadas (Indice de Gravedad Lesional 20,5 y 21,5 respectivamente). Más de la mitad de las lesiones de ambos órganos era mayor y entre el 72 por ciento y el 86 por ciento se acompañaron de hemoperitoneo. El 18 por ciento de los pacientes con lesión hepática requirió transfusión (0,45 U/paciente) y el 20 por ciento de los con lesión de bazo fueron transfundidos (0,40 U/paciente). Sólo un paciente con lesión hepática y dos con lesión esplénica debieron ser operados, lo que significa un éxito de la conducta no operatoria del 95,5 por ciento y 86.6 por ciento respectivamente. No hubo mortalidad ni complicaciones tardías. Se concluye que el manejo no-operatorio del trauma de hígado o bazo es una alternativa segura de tratamiento en casos seleccionados

A rare form of atrioventricular septal defect with severe subaortic stenosis.

An unusual form of atrioventricular septal defect associated with severe subaortic obstruction is reported in a neonate who presented with intractable cardiac failure. The baby had a large defect in the atrioventricular septum allowing communication from the left ventricle to the right atrium, without interatrial or interventricular communication, and a cleft anterior mitral leaflet. The baby expired despite palliative surgery performed to bypass the subaortic stenosis.

Resultados del tratamiento de 588 pacientes con trauma múltiple / Treatment results in 588 patients with multiple trauma

Background: Ten to fifteen million wounded and 700,000 deaths each year, around the world, are the consequences of accidents, according to the World Health Organization. In Chile 2,269 deaths occur each year due to accidents. The successful treatment of these patients requires a schematized initial management, that is taught in the Advanced Trauma Life Support Courses. Aim: To review the results of trauma treatment using this model at Hospital del Trabajador in Santiago. Patients and methods: A retrospective review of patients with trauma treated between 1984 and 1994. The severity of trauma was classified according to the Injury Severity Score. Results: Five hundred eighty eight patients (60 female) aged 35.4ñ14 years old were treated in the period. Vehicular accidents accounted for 62 percent of trauma. The most frequently injured corporal segments were limbs and pelvis in 79 percent, head and neck in 66 percent and thorax in 44 percent. There were 2.45 lesions per patient. Mortality was 8 percent and, among survivors, 79 percent had a complete recovery and were reintegrated to their usual activities. Fifteen percent of patients were severely injured. Among these, mortality was 28 percent and 43 percent of survivors had some sequel. Head injuries had a predominant role in mortality and post traumatic disabilities. Conclusions: These results confirm the efficacy of Advanced Trauma Life Support system in the treatment of patients with multiple trauma

Tratamiento no operatorio de traumatismo de hígado y bazo: experiencia clínica / Non surgical treatment of liver and spleen trauma: clinical experience

Patients and methods: Clinical charts of 21 patients with traumatic lesions of liver or spleen that were not operated, seen between 1991 and 1996, were reviewed. Severity of trauma was assessed according to the Abbreviated injury scale of 1985 and CAT scan lesions were scored according to scale proposed by the American Association of Trauma Surgery. Results: Mean age of patients was 33.4 years old and 17 were male. Twelve patients had liver trauma, that had a mean severity index of 20.1. According to abdominal CAT scan, two patients had grade II lesions, 8 had grade III lesions and 2 had grade IV lesions. Two patients required transfusions and all had a successful recovery. Nine patients had spleen trauma, with a severity score of 24.4. Three patients required transfusions and one was subjected to a splenectomy. Mean hospital stay was 17.8 days for patients with liver trauma and 16 days for patients with spleen trauma. Conclusions: Non operative management of liver and spleen trauma is feasible and safe in a selected group of patients, independent of the degree of injury and hemoperitoneum

Cirugía del traumatismo esplénico / Surgery of splenic injury

Con el objetivo de analizar nuestra experiencia frente a los traumatismos del bazo y sus resultados, revisamos el tratamiento quirúrgico de los traumatismos esplénicos en el período 1982-1993. Fueron operados 26 pacientes, todos secundarios a una contusión abdominal. Destaca que 22 de 26 son politraumatizados con un ISS medio de 25. Existieron 3,17 lesiones intraabdominales por paciente siendo el hígado, riñ+on y diafragma los órganos más frecuentemente asociados. Se practicó una esplenectomía en 14 pacientes, con una mortalidad del 7,1 porciento. En los 12 restantes se efectuó cirugía conservadora del bazo, mediante técnicas de sutura, uso de agentes tópicos y malla reabsorbible. En este grupo no hubo mortalidad ni necesidad de reexploraciones. Entre ambos grupos no hubo diferencias entre el ISS (25 versus 27) ni en el tiempo operatorio (120 minutos versus 125 minutos). Destaca que en el grupo de esplenorrafia la mayoría de las lesiones fueron de grado I al III. Creemos demostrar que se puede aplicar en forma segura un tratamiento quirúrgico selectivo en adultos con traumatismo del bazo, con un 46,4 porciento de éxito en la preservación esplénica

Utilidad de la resonancia magnética en el diagnóstico de ruptura diafragmática en 3 casos / Utility of magnetic resonance in the diaphragmatic rupture diagnosis in 3 cases

We report three male patients in whom the diagnosis of diaphragmatic rupture was raised. Conventional X ray examination showed an unilateral bulging of the diaphragmatic dome in 2 and the association of basal atelectasis in the third. Magnetic resonance imaging confirmed the diagnosis of diaphragmatic rupture in all. The diaphragmatic rupture was repaired surgically in two patients and the other was managed medically
