RESUMO

Introduction. Perinatal arterial ischaemic stroke (PAIS) is almost as common as in adulthood and causes significant neurological sequelae. Aim. The aim is to describe the risk situations surrounding these neonates, the clinical manifestations, the management, the cost-effectiveness of diagnostic tests and the neurological sequelae. Patients and methods. We conducted an observational study of a cohort of patients consisting of neonates with a gestational age = 35 weeks diagnosed with PAIS in our hospital between 2010 and 2021. Results. Twenty-two cases of PAIS were included, and the incidence in our centre was 1/1,869 live newborns. The data showed that 81.8% had some intrapartum risk factor and 40.9% had a combination of several risk factors. It started with seizures (mean age 27.3 hours) in 77.3% of cases. Patients with a stroke in the left hemisphere had more sequelae (77.8%) than those with a stroke on the right-hand side (16.6%) (p = 0.041), with the exception of infantile cerebral palsy (p = 0.04), while we found no difference between hemispheres in the frequency of language impairment (p = 0.06). The mean follow-up time was 6.13 ± 3.06 years. A total of 63.6% of infants had neurological sequelae: infantile cerebral palsy (40.9%), language disorders (22.7%) and intellectual disability (9%). Moreover, 18.2% developed epilepsy (between 0.25 and 1.8 years) and antiseizure treatment was maintained after discharge in 37.5% of cases in the last years of the study. Conclusions. If a newborn infant presents seizures, it is necessary to rule out the possibility of a stroke. PAIS causes neurological sequelae in over 60% of cases. Early identification is essential to improve the neurological prognosis and avoid the prolonged use of antiseizure drugs where possible. (AU)

RESUMO

Introducción: La púrpura de Schönlein-Henoch (PSH) es una vasculitis de pequeños vasos sanguíneos, mediada inmunológicamente, aunque su patogenia exacta aún es desconocida. Se caracteriza por la presencia de púrpura cutánea palpable, afectación articular y gastrointestinal, pero el pronóstico a largo plazo estará determinado por la aparición de alteraciones renales. Caso clínico: Se describe el caso de una niña diagnosticada de PSH, que asoció desde el inicio del cuadro un intenso dolor lumbar sin antecedente traumático previo, y fue diagnosticada tardíamente de hematoma muscular abdominal. Discusión: La asociación de hematomas musculares en el curso de la PSH se considera una complicación muy infrecuente. Existen escasas referencias en la literatura al respecto, si bien puede causar una morbilidad importante. Conclusión: La rareza de esta complicación en la PSH infantil puede dificultar su diagnóstico precoz y su correcta interpretación


Introduction: Henoch-Schönlein purpura is a small-vessel IgA immune complex-mediated vasculitis, of unknow pathogenesis, characterized by of palpable purpura (without thrombocytopenia), abdominal pain, renal disease, and arthritis/arthralgias. It may also present with gastrointestinal bleeding. Case report: We report the case of a child with a Henoch-Schönlein purpura with a severe low back pain, without history of previous trauma, that was later diagnosed as an abdominal muscular hematoma through imaging test using ultrasound scan and lumbar radiography. Conclusion: Even though muscular affection was considered at first as an accidental finding, bibliographical research on the subject revealed published references to similar lesions in previous cases of this disease

RESUMO

Background: Orthostatic hypotension (OH) is a common disorder, and possibly underdiagnosed. In the elderly, OH has been considered a common cause of falls, fractures, and fear of falling. Its prevalence increases with age, probably related to the number of drug treatments, decreased fluid intake, and the progressive dysfunction of the autonomic nervous system. Objectives: To evaluate the prevalence of OH in a non-institutionalised population ≥80 years, according to different criteria based on sequential measurements taken at minute 0, 1, 3 and 5 of standing. Methods design: A diagnostic accuracy study using an oscillometric device. Setting and participants: Convenience sampling of 176 people ≥80 years attended in an urban Primary Health Care Centre. Measurements: Supine and standing blood pressure (BP) measurements, at minutes 0, 1, 3 and 5 using the OMRON 705-CP blood pressure device. OH definition: decrease ≥20 mmHg in systolic BP (SBP) and/or ≥10 mmHg in diastolic BP (DBP). Results: Mean age (Standard Deviation) was 85.2 (3.7) years, and 60.2% were women. Prevalence of OH: 30.7% at minute 0; 19.3% at minute 1; 18.2% at minute 3; and 20.5% at minute 5. Age, sedentary life, smoking, diabetes and SBP values were significantly associated with a greater BP decrease at minute 0. Conclusion: A third of the sample had OH, with a maximum prevalence at minute 0. From a clinical point of view, it is suggested that the definition of OH is prioritized according to the BP at minute 0


Introducción: La hipotensión ortostática (HO) es un fenómeno muy común posiblemente infradiagnosticado. En ancianos, la HO puede causar caídas, fracturas y miedo a caerse. Su prevalencia aumenta con la edad, seguramente en relación con el número fármacos prescritos, la disminución de ingesta de líquidos y la disfunción progresiva de su sistema nervioso autónomo. Objetivos: Evaluar la prevalencia de OH en ancianos mayores de 80años no institucionalizados según el criterio diagnóstico de HO en medidas secuenciales tomadas en los minutos 0, 1, 3 y 5 de bipedestación. Sujetos y métodos: Diseño: estudio de diagnóstico mediante aparato de presión oscilométrico. Muestra: muestreo a conveniencia de 176 pacientes ≥80 años atendidos en un centro de atención primaria urbano. Medidas: Presión Arterial (PA) en supinación y a los minutos 0, 1, 3 y 5 mediante un tensiómetro OMRON 705-CP. Definición de HO: descenso ≥20 mmHg en la PA sistólica (PAS) y/o ≥10 mmHg en la PA diastólica. Resultados: La media de edad (desviación estándar) fue de 85,2 (3,7) años, y el 60,2% fueron mujeres. Prevalencia de HO: 30,7% al minuto 0; 19,3% al minuto 1; 18,2% al minuto 3; 20,5% al minuto 5. Edad, sedentarismo, tabaquismo, diabetes y valores de PAS mostraron una asociación significativa con un mayor descenso de la PA en el minuto 0. Conclusión: Un tercio de la muestra presenta HO, con un máximo de prevalencia en el minuto 0. Desde el punto de vista clínico parece recomendable priorizar la definición de la HO según la PA en el minuto 0

RESUMO

Los adenomiomas gástricos son tumores benignos extremadamente infrecuentes en la población pediátrica, cuya histología recuerda al componente epitelial de los conductos pancreáticos. Presentamos un caso de un adenomioma pilórico que simuló clínicamente una estenosis hipertrófica de píloro en una niña recién nacida. Las pruebas radiológicas, fundamentalmente la resonancia magnética, fueron muy importantes en la caracterización y el diagnóstico de esta entidad (AU)

RESUMO

OBJETIVO: Las endofugas tipo II (EFII) pueden incrementar la tasa de complicaciones. Se evaluó la relación entre la cantidad de trombo en el saco con el desarrollo de EFII y el crecimiento del aneurisma. MATERIAL Y MÉTODO: Se estudió a 103 pacientes tratados mediante EVAR. El grosor máximo del trombo (GMT), los porcentajes del área (PAOT) y perímetro aórticos con trombo (PPCT, PTHP) y el grosor (GMHP) en la cara posterior se determinaron en la TC preoperatoria en: zona A (diámetro máximo), zona B (entre zona A y bifurcación) y zona C (entre inicio del aneurisma y zona A). Se cuantificó el número de ramas permeables y el diámetro del saco durante el seguimiento. RESULTADOS: Hubo 51 endofugas (49,5%). Los pacientes con EFII presentaron unos GMT (18,6 vs. 24 mm; p = 0,01) y GMHP (13,9 vs. 18,9 mm; p = 0,003) menores en la zona A y tenían un PAOT (49,7 vs. 65,4%; p < 0,001), PPCT (72,4 vs. 82,3%; p < 0,001) y PTHP (63,7 vs. 74,7%; p = 0,03). El número medio de ramas fue de 5 en los pacientes sin EFII frente a 6 en los que la tenían (p = 0,004). Se observó un riesgo de EFII menor con: PAOT (OR = 0,65 por cada aumento del 10%; IC 95%: 0,44-0,98; p = 0,03), PPCT en la zona B (OR = 0,69 por cada aumento del 10%; IC 95%: 0,50-0,95; p = 0,01) y C (OR = 0,68; IC 95%: 0,52-0,88; p = 0,002), GMHP en la zona A (OR = 0,71 por cada aumento de 5 mm; IC 95%: 0,49-0,99; p = 0,04) y PTHP en la B (OR = 0,81 por cada aumento del 10%; IC 95%: 0,67-0,9; p = 0,02). La arteria mesentérica inferior (AMI) permeable (OR = 3,1; IC 95%: 1,1-8,9; p = 0,033), el mayor número de ramas (OR = 4,6 con más de 4 vasos; IC 95%: 1,8-12,2; p = 0,024) y lumbares (OR = 1,9 por cada incremento en una lumbar; IC 95%: 1,1-3,5; p = 0,017) se asociaron a un mayor riesgo. Cuanto mayor era el PAOT, PPCT, GMHP y PTHP mayor era la tendencia a la regresión/estabilidad del saco. CONCLUSIONES: La cuantificación de la carga de trombo y número de ramas permeables permite determinar pacientes con mayor riesgo de EFII y crecimiento del saco durante el seguimiento


BACKGROUND: Type II endoleaks (ELII) may increase the complication rate. An evaluation was made of the association between thrombus load and development of ELII, and aneurysm sac growth. MATERIAL AND METHODS: A total of 103 endovascular aortic repair patients were analyzed. The maximum thrombus thickness (GMT), percentages of area (PAOT) and perimeter lined by thrombus (PPCT), and posterior thickness (GMHP) were determined from pre-operative CT at 3 levels: zone A (maximum diameter), zone B (from zone A to bifurcation), and zone C (from neck to zone A). The number of aortic side branches was recorded, and sac diameter was measured during follow-up. RESULTS: A total of 51 endoleaks (49.5%) were noted. Patients with ELII had significantly less GMT (24.0 vs. 18.6 mm, P=0.01) and GMHP (13.9 vs. 18.9 mm, P=0.003) in zone A, and PAOT (49.7 vs.65.4%, P<0.001), PPCT (72.4 vs. 82.3%, P<0.001), and PTHP (63.7 vs. 74.7%, P=0.03). The average number of side branches was 5 in patients without ELII versus 6 with (P=0.004). Lower risk of ELII was observed with: PAOT (OR = 0.65 for a 10% increase, 0.44-0.98, P=0.03), PPCT in zone B (OR = 0.69 for each 10% increase, 0.50-0.95, P=0.01), and C (OR = 0.68, 0.52-0.88, P=0.002), GMHP in zone A (OR = 0.71 for each 5 mm increase, 0.49-0.99, P=0.04), and PTHP in zone B (OR = 0.81for 10% increase, 0.67-0.99, P=0.02). The patent IMA (OR = 3.1, 1.1-8.9, P=0.033), the number of patent branches (OR = 4.6 with more than 4 branches, 1.8-12.2, P = 0.024), and lumbar branches (OR = 1.9 for each patent lumbar, 1.1-3.5, P=.017) were associated with an increased risk of ELII. The greater PAOT, PPCT, GMHP, and PTHP were, the higher regression/stability of the sac was. CONCLUSIONS: Quantification of the thrombus load and the number of patent side branches can be used to determine patients at increased risk of ELII and sac growth during follow-up

RESUMO

Objetivo: Analizar los efectos del clampaje suprarrenal (CSR) frente al clampaje infrarrenal (CIR) en la evolución de la función renal en la cirugía del aneurisma de aorta abdominal (AAA). Material y método: Estudio de cohortes retrospectivo de los AAA tratados mediante cirugía abierta electiva entre 1998 y 2011. Se analizó la creatinina sérica (mg/dl) preoperatoria y a las 24, 48, 72, 96 h postoperatorias y al alta. Se definió deterioro de la función renal como una creatinina > 2 mg/dl en los pacientes con una creatinina basal normal o un aumento del doble de la creatinina basal en los pacientes con IRC previa. Se definió deterioro del filtrado glomerular (FG) como una disminución > 25%. Análisis multivariable de la evolución de la función renal. Resultados: Se analizaron 464 AAA, 359 (77,4%) con CIR y 105 (22,6%) con CSR. La prevalencia de IRC preoperatoria fue similar entre ambos grupos. El tipo de clampaje no se asoció a deterioro de la función renal (CSR = 8,6% vs. CIR = 4,7%; p = 0,13) y sí al deterioro del FG (CSR = 27,6% vs. CIR = 13,4%; p = 0,001). El tiempo de clampaje, la pérdida sanguínea y la IRC preoperatoria fueron factores de riesgo independientes para deterioro de la función renal. El tipo de clampaje aumentó el riesgo de deterioro de la función renal a partir de los 30 min (p = 0,001), asociándose a deterioro del FG (OR 2,04; IC 95% 0,94-4,47) de forma independiente. Conclusión: Con CSR inferiores a 30 min, en pacientes con creatinina normal, no es previsible un deterioro de la función renal. Con IRC previa o si se espera un CSR prolongado, es esperable un deterioro de la función renal, por lo que deberían valorarse métodos de protección renal (AU)


Objective: To analyse the effects of suprarenal cross-clamping (SC) as opposed to the infrarenal position (IC) in the evolution of the renal function abdominal aorta aneurysm (AAA) surgery. Material and method: A retrospective cohort study of AAAs treated by elective open surgery between 1998 and 2011. The preoperative level of serum creatinine (mg/dL) was determined and compared to postoperative level at 24, 48, 72 and 96 hours, and on discharge. A deterioration in the renal function was defined as a creatinine > 2 mg/dL in patients with a normal baseline creatinine level or an increase of double the baseline creatinine in patients with a previous chronic renal insufficiency (CRI). A deterioration of the glomerular filtrate (GF) was defined as a > 25% decrease. Multivariable analysis was performed on the evolution of the renal function. Results: A total of 464 AAA’s were analysed, 359 (77.4%) with IC, and 105 (22.6%) with SC. The prevalence of preoperative CRI was similar in both groups. The type of clamp was not associated with a deterioration in the renal function (SC = 8.6% vs. IC = 5.7%; p = 0.13) but was associated with a deterioration of the GF (SC = 27.6% vs. IC = 13.4%; p = 0.001). The time the clamp was in place, the blood loss, and the preoperative CRI were independent risk factors for the deterioration of the renal function. The type of clamp increased the risk of deterioration of the renal function beyond 30 minutes (p = .001), being independently associated with a deterioration in the GF (OR 2.04; 95% CI: 0.94-4.47). Conclusion: With SC less than 30 min, in patients with a creatinine level, a deterioration in the renal function is not foreseeable. With prior CRI, or if a prolonged SC is foreseen, a deterioration in the renal function can be expected, thereby making it necessary to evaluate methods for renal protection (AU)

RESUMO

A pesar de su sencillez estructural, las plaquetas son células funcionalmente muy complejas debido a su capacidad para producir y liberar biomoléculas. De aquí su importancia en el desarrollo de la arteriosclerosis. Se realizó un experimento in vitro para estudiar la actividad de las plaquetas sobre la pared vascular observando los cambios en la expresión proteica del citoesqueleto en segmentos de aorta bovina incubados con plasma rico en plaquetas. Para intentar simular un estado inflamatorio (arteriosclerosis), se realizaron estas mismas determinaciones en segmentos preestimulados con factor de necrosis tumoral. Se observó una modulación de la expresión de la mayoría de las proteínas del citoesqueleto en los segmentos de aorta sana. Sin embargo, en los segmentos preestimulados el número de proteínas fue menor, pudiendo reflejar una capacidad dual de las plaquetas para alterar la contractilidad vascular en función del estado inflamatorio de la pared vascular (AU)


Despite its structural simplicity, platelets are functionally complex cells due to their ability to produce and release biomolecules. Hence its importance in the development of atherosclerosis. An in vitro experiment was conducted to study the effect of the platelets on the vascular wall by observing changes in the cytoskeletal protein expression in bovine aortic segments incubated with platelet rich plasma. With the aim of simulating an inflammatory state (atherosclerosis), these same measurements were performed on aortic segments pre-stimulated with tumour necrosis factor. We observed a modulation of the expression of most of the cytoskeletal proteins in healthy aorta segments. However, the number of modified proteins was less in pre-stimulated segments. These results may reflect a dual platelet capacity to alter vascular contractility in relation to the inflammatory condition of the vascular wall (AU)

RESUMO

AIM: Traumatic aortic injury is usually lethal, most often because of serious associated wounds. The short- and midterm outcome of endovascular exclusion was assessed as the current treatment of choice due to a lower mortality and morbidity than open surgical treatment. METHODS: We reviewed the cases of 8 patients (5 male, mean age 33 years) undergoing endovascular repair of a traumatic thoracic aortic lesion, confirmed by computed tomographic angiography, at our centre. Most patients showed a contained lesion limited to the aortic isthmus and severe associated injuries. RESULTS: Intrahospital mortality was 37.5% (N.=3) and mostly due to posttraumatic brain injury (N.=2). Most patients were hemodynamically stable at the time of endovascular repair (N.=6). The median time to surgery was 12 hours (3-48 hours). The endografts used were TAG® (W.L. Gore and Associates, Flagstaff) in three patients, and Valiant® (Medtronic, Santa Rosa, CA) in four. The technical success rate was 100%. In one case, the left subclavian artery was occluded without signs of arm ischemia. There were no cases of paraplegia or stroke related to treatment. No revision procedures were needed during follow-up. CONCLUSION: Endovascular repair shortly after injury seems to be effective and safe with a low associated morbidity and mortality.
