Adequate timing of diagnostic tests for gastroesophageal reflux in children with esophageal atresia. / Momento adecuado para las pruebas diagnósticas de reflujo esofágico en pacientes con atresia de esófago.

OBJECTIVE: Recent guidelines made recommendations for the management of gastroesophageal reflux in patients with esophageal atresia (EA). However, the timing for some diagnostic tests remained somehow unclear. This investigation studied the tests for gastroesophageal reflux in children aged one year old and children aged two or three. MATERIALS AND METHODS: Patients with EA who underwent Multichannel Intraluminal Impedance-pH monitoring (MII-pH) and endoscopy-histology were studied retrospectively. Patients aged one when the test was performed were the YO group and patients aged two or three years old formed the OL group. Substantially impaired MII-pH was defined as total number of reflux episodes >105 or >85 (depending on age), or reflux index >10%. Substantially impaired endoscopy was defined as erosive esophagitis or Barrett's esophagus. Substantially impaired histology was defined as moderate-severe esophagitis or Barrett's esophagus. Conventional parameters and substantially impaired values of the tests were compared. RESULTS: Twenty-four patients were studied. Twenty-three MII-pH were performed (12 in YO and 11 in OL): percentages of abnormal conventional parameters of MII-pH were not significantly different in both groups. Twenty endoscopies with biopsies were performed (7 in YO and 13 in OL): percentages of esophagitis were not significantly different. Interestingly, 26.9% of all the tests performed in YO were substantially impaired vs. 10.8% of all the tests in OL (χ2 = 2.7; p = 0.1). CONCLUSION: Considering the percentage of alarming results of diagnostic tests in the YO group it would be advisable that patients with EA undergo MII-pH and endoscopy-histology at one year of age.

OBJETIVOS: Recientemente se han publicado recomendaciones para el manejo del reflujo gastroesofágico en pacientes con atresia de esófago (AE). Sin embargo, el momento de realización de algunas pruebas no está completamente aclarado. Esta investigación evalúa las pruebas para reflujo gastroesofágico en niños de 1 año y niños de 2-3 años. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con AE sometidos a impedanciometría-phmetría (IMpH) y a endoscopia-histología. Los pacientes con 1 año en el momento de la prueba formaron el grupo MEN, y los pacientes con 2-3 años, el grupo MAY. Se consideró IMpH sustancialmente alterada aquella con un número total de reflujos >105 o >85 (según la edad), o un índice de reflujo >10%. La endoscopia se consideró sustancialmente alterada si presentaba esofagitis erosiva o esófago de Barrett. La histología se consideró sustancialmente alterada si presentaba esofagitis severa-moderada o esófago de Barrett. Se compararon los parámetros convencionales y los sustancialmente alterados. RESULTADOS: Se estudiaron 24 pacientes. Se realizaron 23 IMpH (12 en el grupo MEN y 11 en el MAY); los porcentajes de los parámetros convencionales patológicos no fueron estadísticamente diferentes en ambos grupos. Se realizaron 20 endoscopias (7 en el grupo MEN y 13 en el MAY); los porcentajes de esofagitis no fueron estadísticamente diferentes. El 26,9% de todas las pruebas en el grupo MEN resultaron sustancialmente alteradas, frente al 10,8% en el MAY (χ2 = 2,7; p = 0,1). CONCLUSION: Teniendo en cuenta el porcentaje de resultados alarmantes en el grupo MEN, sería recomendable realizar una IMpH y una endoscopia con biopsias a los pacientes con AE a la edad de un año.

Early versus conventional nutritional intervention in head and neck cancer patients before radiotherapy: benefits of a fast-track circuit.

BACKGROUND/OBJECTIVES: Radiotherapy (RT) is a component of therapy for head and neck cancer (HNC) with a negative nutritional impact. Our aim was to compare an early versus a conventional nutritional intervention. SUBJECTS AND METHODS: Retrospective study of HNC patients undergoing RT. Evolution before and after the establishment of a fast-track circuit was evaluated. A conventional group (CG) made up of patients submitted to the nutrition unit during RT after nutritional deterioration, was compared to an early group (EG) represented by patients included in a fast-track circuit, starting nutritional follow-up before the beginning of RT. Only patients with preserved oral intake were involved. Demographic, nutritional and clinical variables were analyzed. Data of hospitalizations and deaths were collected up to three months after RT. RESULTS: 135 subjects constituted the EG and 39 the CG. At baseline, the prevalence of malnutrition was lower in the EG (31.9% vs 69.5%, p = 0.0001), as was the need for nutritional supplements (40% vs 79.5%, p = 0.0001) or nasogastric tube (0% vs 12.8%, p = 0.0001) in comparison to the CG. Three months after RT, there were less patients with oral nutritional support in the EG (79.1% vs 96.9%, p = 0.018), and the number of emergency visits (0.75 vs 1.1 episodes per patient, p = 0.021) and hospitalizations was also lower in this group (29% vs 59%, p = 0.044). CONCLUSIONS: The fast-track approach made early intervention possible. Therefore, patients maintained a better nutritional status, needed less nutritional support and their evolution improved, with a significant decrease in hospitalizations.

Aplicabilidad de un score clínico en pacientes con sospecha de aspiración de cuerpo extraño / Applicability of a clinical score in patients with suspected foreign body aspiration

Objetivos. Validar el score clínico de Valdivieso y cols. en el manejo de los pacientes con sospecha de aspiración de cuerpo extraño en un hospital de tercer nivel. Dicho score plantea escenarios diferentes según la puntuación obtenida: broncoscopia, TAC, observación o alta. Material y métodos. Estudio retrospectivo de los pacientes a los que se realizó una broncoscopia por sospecha de cuerpo extraño entre noviembre de 2015 y noviembre de 2018. Se recogieron las variables propuestas por el score (atragantamiento presenciado, estridor, sibilancias, hipoventilación unilateral, radiografía alterada y cuerpo extraño de riesgo) y su puntuación para cada paciente, analizando el rendimiento de la prueba mediante la curva COR (característica operativa del receptor). Resultados. Se realizó broncoscopia en 81 pacientes con una edad media de 2,1 años (7 meses-11 años), encontrando cuerpo extraño en el 33,3%. El área bajo la curva COR del score fue de 0,803 (0,695-0,911). En 6 (22,2%) pacientes con cuerpo extraño confirmado el score indicaba inicialmente observación en 5 casos y alta en 1. Excluyendo a los 49 pacientes con atragantamiento con fruto seco o con auscultación alterada unilateral, a los que en nuestro medio se indica directamente broncoscopia, el score clasificó correctamente a los 32 pacientes restantes, lo que hubiese reducido el porcentaje de broncoscopias "blancas" en un 21%. Conclusiones. El score presenta en nuestra muestra un alto rendimiento diagnóstico pero una tasa de falsos negativos no despreciable. En cambio, tiene una especial utilidad en los pacientes que no presentan atragantamiento con fruto seco y/o auscultación alterada unilateral, permitiendo reducir broncoscopias blancas

Objective. To validate the clinical score of Valdivieso et al. in the management of patients with suspected foreign body aspiration in a tertiary hospital. This score raises different scenarios according to the result: bronchoscopy, CT, observation or discharge. Material and methods. Retrospective study of patients who under-went a bronchoscopy due to suspected tracheobronchial foreign body between November-2015 and November-2018. The variables proposed by the score were collected (choking, stridor, wheezing, unilateral hypoventilation, altered chest X-ray and high-risk foreign body) and the score was calculated for each patient, analyzing the performance of the test using the ROC (Receiver Operating Characteristic) curve. Results. Bronchoscopy was performed in 81 patients with a mean age of 2.1 years (7 months-11 years), finding foreign body in 33.3%. The area under the ROC curve of the score was 0.803 (0.695-0.911). In 6 (22.2%) patients with confirmed foreign body the score initially indicated observation in 5 cases and discharge in 1. Excluding the 49 patients with unilateral altered auscultation or when there was a nut suspected, which in our environment are clear indications for bronchoscopy, the score correctly classified the remaining 32 patients, which would have reduced the rate of normal bronchoscopies from 66% to 45%. Conclusions. The score in our sample presents a high diagnostic power but a non-negligible false negative rate. It has a special utility in patients who do not have unilateral altered auscultation and/or choking with nuts, allowing to reduce the rate of normal bronchoscopies

Prognostic factors in neoadjuvant treatment followed by surgery in stage IIIA-N2 non-small cell lung cancer: a multi-institutional study by the Oncologic Group for the Study of Lung Cancer (Spanish Radiation Oncology Society).

PURPOSE: To evaluate the prognostic factors associated with survival in patients treated with neoadjuvant treatment [chemoradiotherapy (CRT) or chemotherapy] followed by surgery (CRTS) in patients with stage IIIA-N2 non-small cell lung cancer (NSCLC). METHODS: A retrospective study was conducted of 118 patients diagnosed with stage T1-T3N2M0 NSCLC and treated with CRTS at 14 hospitals in Spain between January 2005 and December 2014. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method and compared using the log-rank test. Cox regression analysis was performed. RESULTS: Surgery consisted of lobectomy (74.5% of cases), pneumectomy (17.8%), or bilobectomy (7.6%). Neoadjuvant treatment was CRT in 62 patients (52.5%) and chemotherapy alone in 56 patients (47.5%). Median follow-up was 42.5 months (5-128 months). 5-year OS and PFS were 51.1% and 49.4%, respectively. The following variables were independently associated with worse OS and PFS: pneumonectomy (vs. lobectomy); advanced pathologic T stage (pT3 vs. pT0-pT2); and presence of persistent N2 disease (vs. ypN0-1) in the surgical specimen. CONCLUSIONS: In this sample of patients with stage IIIA-N2 NSCLC treated with CRTS, 5-year survival (both OS and PFS) was approximately 50%. After CRTS, the patients with the best prognosis were those whose primary tumour and/or mediastinal nodal metastases were downstaged after induction therapy and those who underwent lobectomy. These findings provide further support for neoadjuvant therapy followed by surgery in selected patients.

Esplenectomía en enfermedades hemolíticas. Influencia de la enfermedad de Gilbert en la aparición de complicaciones biliares / No disponible

Introducción: En pacientes con enfermedades hemolíticas (EH) se recomienda esplenectomía entre 6-12 años. En aquellos con enfermedad de Gilbert (EG) asociada se ha descrito mayor riesgo de complicaciones biliares (CB), sin establecerse edad quirúrgica óptima. Nuestro objetivo es cuantificar el riesgo de CB en pacientes con EH y EG para valorar el beneficio de esplenectomía temprana. Material y métodos: Estudio retrospectivo de las esplenectomías realizadas en pacientes con EH entre 2000-2017. Se analizó la incidencia de CB, su repercusión clínica (ingreso o tratamiento invasivo) y momento de aparición. Se consideraron dos grupos: pacientes con EG y sin EG. Se obtuvieron curvas de supervivencia y se compararon mediante log-rank test. Resultados: Se realizaron 44 esplenectomías, 15 de ellas (34,1%) en pacientes con EH+EG. La edad mediana en la cirugía fue 10,3 años (rango 5,4-14,8). Veintinueve (65,9%) presentaron CB. El 50% de los pacientes con EG las presentaron antes de los 8 años vs.10,5 años en los casos sin EG (log-rank 3,9; p= 0,05). Los pacientes con EG presentaron más CB (86,7% vs. 55,2%; c2= 4,37, p= 0,037). En el grupo EH+EG, 8 casos (53%) necesitaron ingreso vs. 8 (31%) en el grupo sin EG (c2= 2, p= 0,1). El tratamiento invasivo fue necesario en 2 pacientes (13%) del grupo EH+EG y 2 pacientes (7,6%) del grupo sin EG (c2= 0,3, p= 0,6). Conclusiones: En nuestra serie, la incidencia de CB fue superior en los pacientes con EG. Existió una tendencia a la presentación más temprana de CB en este grupo, pero ni este dato ni su repercusión clínica nos permiten recomendar la esplenectomía temprana

Introduction: In patients with hemolytic disorders (HD) splenectomy is recommended between 6-12 years. A higher risk of biliary complications (BC) has been described in those with associated Gilbert’s disease (GD), but the ideal surgical age has not been stablished yet. Our aim is to quantify the risk of BC in patients with HD and GD to assess the benefit of early splenectomy. Material and methods: Retrospective study of splenectomies performed in patients with HD between 2000-2017. The incidence of BC, its clinical consequences (admission or invasive treatment) and time of onset were analyzed. Two groups were considered: patients with GD and without GD. Survival curves were obtained and compared with log-rank test. Results: Fourty-four patients underwent splenectomy, 15 of them (34.1%) with HD+GD. The median age at surgery was 10.3 years (range 5.4-14.8). Twenty-nine (65.9%) had BC. Half of the patients with GD had BC before 8 years vs. 10,5 years in the cases without GD (log-rank 3.9, p= 0.05). Patients with GD had more BC (86.7% vs. 55.2%; c2= 4.37, p= 0.037). In the HD+GD group, 8 cases (53%) required admission vs.8 patients (31%) in the group HD without GD (c2= 2, p= 0.1). Invasive treatment was performed in 2 patients (13%) in the HD+GD group and 2 others (7.6%) in the group HD without GD (c2= 0.3, p= 0.6). Conclusions: In our series, the BC incidence was higher in patients with HD and GD. There was a trend towards an earlier presentation of BC in this group, but neither this data nor its clinical consequences allow us to recommend early splenectomy

Neoadjuvant treatment followed by surgery versus definitive chemoradiation in stage IIIA-N2 non-small-cell lung cancer: A multi-institutional study by the oncologic group for the study of lung cancer (Spanish Radiation Oncology Society).

OBJECTIVES: The role of surgery in stage IIIA-N2 non-small cell lung cancer (NSCLC) is an actively debated in oncology. To evaluate the value of surgery in this patient population, we conducted a multi-institutional retrospective study comparing neoadjuvant chemoradiotherapy or chemotherapy plus surgery (CRTS) to definitive chemoradiotherapy (dCRT). MATERIAL AND METHODS: A total of 247 patients with potentially resectable stage T1-T3N2M0 NSCLC treated with either CRTS or dCRT between January 2005 and December 2014 at 15 hospitals in Spain were identified. A centralized review was performed to ensure resectability. A propensity score matched analysis was carried out to balance patient and tumor characteristics (n = 78 per group). RESULTS: Of the 247 patients, 118 were treated with CRTS and 129 with dCRT. In the CRTS group, 62 patients (52.5%) received neoadjuvant CRT and 56 (47.4%) neoadjuvant chemotherapy. Surgery consisted of either lobectomy (97 patients; 82.2%) or pneumonectomy (21 patients; 17.8%). In the matched samples, median overall survival (OS; 56 vs 29 months, log-rank p = .002) and progression-free survival (PFS; 46 vs 15 months, log-rank p < 0.001) were significantly higher in the CRTS group. This survival advantage for CRTS was maintained in the subset comparison between the lobectomy subgroup versus dCRT (OS: 57 vs 29 months, p < 0.001; PFS: 46 vs 15 months, p < 0.001), but not in the comparison between the pneumonectomy subgroup and dCRT. CONCLUSION: The findings reported here indicate that neoadjuvant chemotherapy or chemoradiotherapy followed by surgery (preferably lobectomy) yields better OS and PFS than definitive chemoradiotherapy in patients with resectable stage IIIA-N2 NSCLC.

Quiste epiploico complicado tras una herniorrafia en un lactante / Complicated omental cyst after a herniorrhaphy in an infant

Los quistes de omento son tumoraciones abdominales benignas y excepcionales. En este artículo se describe el caso de un lactante varón intervenido de una hernia inguinal izquierda con epiplón incluido en el sacoherniario. En dicho epiplón, se evidenció un pequeño quiste que se resecó. El postoperatorio inmediato transcurrió sin incidencias hasta que el paciente acudió al hospital siete días después con síntomas y signos de abdomen agudo. Las pruebas de imagen realizadas, así como los hallazgos operatorios, revelaron un quiste de omento complicado. El paciente fue intervenido y el quiste resecado. El diagnóstico histopatológico de la pieza reveló un tumor pseudoinflamatorio. El postoperatorio fue satisfactorio y, desde el alta, el paciente permanece asintomático. En conclusión, es importante explorar el contenido del saco herniario durante una herniorrafia inguinal. Ante el hallazgo de un quiste epiploico en el interior del saco debería valorarse la posibilidad de que existan más lesiones intraabdominales

Omental cysts are uncommon benign masses localized in the abdomen. This article describes the case of a male infant who underwent surgery due to a left inguinal hernia. During the operation a small omental cyst was found inside the sac that was resected. The first postoperative days were uneventful but the infant came back to hospital seven days after. Subsequent imaging and operative findings revealed a complicated mental cyst. This cyst was removed and the histopathology report described an inflammatory pseudo tumor. The postoperative evolution was satisfactory and the patient has remained asymptomatic since he was discharged from hospital. In conclusion, it is important to explore the contents of the hernia sac during inguinal hernia repair. The finding of a small o mental cystinside the sac should encourage to study other potential intraabdominal lesions

Tratamiento conservador de un absceso renal múltiple / Successful conservative management of a multiple renal abscess in a child

Los abscesos renales son poco frecuentes en niños, pero sus consecuencias pueden ser graves, incluyendo sepsis, daños renales graves o la pérdida del riñón. Describimos el caso de una paciente de tres años de edad, diagnosticada de un absceso múltiple en el riñón izquierdo tras un episodio febril. El caso presenta interés debido a la rara forma de presentación de una infección del tracto urinario como absceso renal múltiple, al tamaño y localización diseminada de las lesiones (cuatro abscesos en un riñón) y al tipo de tratamiento realizado, que consistió en antibióticos intravenosos con el fin de preservar el parénquima renal (AU)

Renal abscesses are uncommon in children but their consequences could be serious, including sepsis, severe renal damage or loss of the kidney. The following report describes a three-year-old girl diagnosed of multiple renal abscess in the left kidney after a first episode of fever. The case is significant due to the uncommon presentation of a urinary tract infection as a multiple abscess, the extension of the injuries (there were 4 abscesses in the kidney) and the conservative therapy with intravenous antibiotics which was selected in order to preserve renal tissue (AU)

Ventajas de la analgesia epidural en cirugía mayor neonatal / Benefits of epidural analgesia in major neonatal Surgery

El objetivo de este trabajo es describir y evaluar las ventajas de la analgesia epidural en cirugía mayor neonatal. Para ello, realizamos un estudio de casos controles emparejado (2:1) de pacientes sometidos a cirugía mayor neonatal (CMN) bajo anestesia general que recibieron analgesia epidural (AE) intra y postoperatoria, y controles con anestesia general convencional. El criterio de emparejamiento fue edad, peso y patología basal. Se administró AE intra y postoperatoria por vía caudal con levobupivacaina mediante catéter epidural colocado con apoyo ecográfico. Se estudiaron el tiempo hasta la extubación, el tiempo de tránsito intestinal (presencia de deposiciones), el tipo de analgesia y las complicaciones. Se estudiaron 11 casos (2 atresias esofágicas, 2 hernias diafragmáticas, 1 enterocolitis necrotizante, 3 atresias intestinales, 2 malformaciones anorrectales y 1 extrofia vesical) y 22 controles. Observamos diferencias estadísticamente significativas en tiempo de extubación (OR 12 IC 95% 1,99-72,35; Chi2 p= 0,004, U Mann Whytney p= 0,013) y del tiempo de tránsito intestinal (U Mann Whitney p< 0,001, Or 100, IC 95% 8,06-1239; Chi2 p< 0,0001). No se observaron complicaciones derivadas de la técnica epidural. Por todo ello, consideramos que la AE intra y postoperatoria ayuda a mejorar el manejo postquirúrgico en neonatos y debe ser de elección en centros en los que esta técnica esté disponible (AU)

The aim of this paper is to describe and evaluate the benefits of epidural anesthesia in major surgery neonatal. We have performed a matched case-control (2:1) study of patients undergoing neonatal major surgery (NMSs) who received intra-and postoperative epidural anesthesia (EA) and controls with conventional general anesthesia. The matching criteria were age, weight and baseline pathology. EA was administered by caudal puncture and epidural catheter placed with ultrasound support. Levobupivacaine was selected as anesthetic drug. The time to extubation, intestinal transit time, type of analgesia and complications were studied. This study is based on 11 cases (2 esophageal atresia, 2 diaphragmatic hernias, 1 necrotizing enterocolitis, 3 intestinal atresia, 2 anorectal malformation and 1 bladder exstrophy) and 22 controls. We observed statistically significant differences in time to extubation (95% CI OR 12 1.99 to 72.35; Chi2 p = 0.004, Mann U Whytney p = 0.013) and intestinal transit time (Mann Whitney U p <0.001, 100 Or , 95% CI 8.06 -1 239; Chi2 p <0.0001). There were no complications from epidural analgesia. Therefore we believe that the intra-and postoperative EA helps improve postoperative management in neonates and should be preferred in centers where this technique is available (AU)

Cuando una peritonitis no parece una peritonitis / When a peritonitis does not seems like a peritonitis

La pancreatitis aguda es una entidad que forma parte del diagnóstico diferencial del abdomen agudo de origen apendicular. Aunque su incidencia es baja, se encuentra en aumento y su correcto diagnóstico evita cirugías innecesarias. El objetivo del trabajo es describir la pancreatitis aguda como diagnóstico diferencial de abdomen agudo de origen apendicular. Se realiza un estudio retrospectivo de los pacientes remitidos para valoración de cirugía pediátrica en la urgencia con sospecha de patología apendicular, que fueron diagnosticados finalmente de pancreatitis aguda desde el año 2010. Se incluyen 5 pacientes. Un paciente fue intervenido y su diagnóstico se realizó en el 5º día postoperatorio. La edad mediana al diagnóstico fue de 5 años (rango de 8 meses a 6 años). La mediana de leucocitos en sangre fue de 16.600 /μL (13.400-31.900 /μL), mediana de neutrofilos 14.432 /μL (11.400-29.348 /μL), mediana PCR 11 mg/L (155-4,6 mg/L), mediana amilasa sérica al diagnóstico 651 U/L (10-1.443 U/L). Todos los casos fueron estudiados con ecografía abdominal y tomografía computarizada o resonancia magnética nuclear. Un caso presentó episodios recurrentes de pancreatitis y como complicación un pseudoquiste y una fístula pancreática, precisando a los 9 meses del inicio del cuadro clínico una derivación cistoentérica en Y de Roux. La mediana global de seguimiento de la serie es de 10 meses, con un rango entre 1 y 22 meses, encontrándose todos los pacientes asintomáticos (AU)

Acute pancreatitis should be considered in the differential diagnosis of acute abdominal pain. Although its incidence is low, it has increased in the last years; therefore, an accurate diagnosis is necessary to avoid inappropriate surgeries. The aim of this study is to describe acute pancreatitis in the context of acute abdominal pain, which suggests appendicitis. We performed a retrospective study of all the patients who were admitted in the emergency department due to suspected appendicitis but were finally diagnosed of acute pancreatitis since 2010. Five patients were included in the investigation. One of them underwent surgery and the diagnosis was made on the 5th postoperative day. Median age at diagnosis was 5 years (range from 8 month to 6 years). Median white blood cell was 16,600 /μL (13,400-31,900 /μL), Median differential count of white blood cell was 14,432 /μL (11,400-29,348 /μL) and Median PCR 11 mg/L (155-4.6 mg/L). Median serum amylase at diagnosis was 651 U/L (10-1,443 U/L). All cases were studied with ultrasound and computerized tomography or nuclear magnetic resonance. One case had recurrent episodes of pancreatitis and was complicated by the development of a pseudocyst and a pancreatic fistula, requiring an Y-en-Roux cysto-enteric anastomosis . The median follow up period was 10 months (range: 1 to 22). All patients are asymptomatic at the moment (AU)

Relación entre la transfusión de concentrado de hematíes y la gravedad de la enterocolitis necrotizante en prematuros / Relation between packed red blood cell transfusion and severity of necrotizing enterocolitis in premature infants

Objetivo. Se ha propuesto que las transfusiones de concentrado de hematíes (TCH) determinan formas de enterocolitis necrotizante (ECN)más severas. Se pretende investigar si las ECN con antecedente de TCH alcanzan una mayor gravedad. Material y métodos. En un estudio retrospectivo de prematuros con ECN se consideraron dos grupos: con antecedente de TCH (grupoTR) y sin antecedente de TCH (grupo No-TR). Se consideraron como resultados principales la gravedad de la ECN, determinada según el estadio de Bell (EB) mayor durante el transcurso de la enfermedad, si fue necesario realizar tratamiento quirúrgico y la mortalidad. Posteriormente se analizaron por separado aquellos pacientes que habían recibido la TCH en las 48 h previas al inicio de los síntomas. Al comparar los grupos se utilizó la prueba exacta de Fisher o la de Chi cuadrado para elEB, el tratamiento quirúrgico, la mortalidad y las variables cualitativas (..) (AU)

Objective. It has been proposed recently that red blood cell transfusions(RBCT) might increase severity in infants with necrotizing enterocolitis (NEC). We intend to study if patients who have received red blood transfusions before the onset of NEC develop more severe forms of this entity. Methods. A retrospective study was carried out including prematures with NEC. Two groups were considered: with previous RBCT(TR) and without previous RBCT (No-TR). The main outcomes of the study were severity of NEC, according to the Bell stage (BS), surgical treatment and mortality. Patients who were treated with RBCT 48hours prior to the onset of NEC symptoms were analysed separately afterwards. Comparison of groups was made with the Fisher test or the Chi square test for the BS, surgery, mortality and nominal variables; the U Mann-Whitney test was used for numeric variables. Results. Forty-six patients were included for the investigation (28 in TR and 18 in No-TR). In the TR Group 20/28 neonates reached a BS II;8/28 BS III; 10 were operated on and there were 7 deaths. In the No-TR group 14/18 patients were classified as EB II; 4/18 as BS III, 3 patients (AU)

Estimación del riesgo de hemorragia digestiva alta en pacientes con cavernomatosis portal / Estimation of the risk of upper digestive tract bleeding in patients with portal cavernomatosis

Objetivos. Determinar el riesgo de hemorragia digestiva alta (HDA)tras el diagnóstico de cavernomatosis portal (CP) en pacientes pediátricos y estudiar las variables que se relacionan con este riesgo. Material y métodos. Analizamos retrospectivamente 13 casos de CP y estimamos las funciones de supervivencia para el evento HDA mediante el método de Kaplan-Meier. Se ha calculado la tasa de incidencia de la muestra y el número de sangrados/año de forma individual. Desde el momento del diagnóstico estudiamos: edad de presentación, plaquetas, leucocitos, hemoglobina, hematocrito, tiempo de protrombina, número de episodios de sangrado. Se ha analizado la relación de estas variables con el riesgo de sangrado individual mediante regresión de Cox. Resultados. Mediana de seguimiento: 7,1 años. 10 pacientes (77%)han presentado algún episodio de HDA tras el diagnóstico. Mediana de supervivencia hasta el primer episodio de HDA después del diagnóstico:314 días. Tasa de incidencia (TI) de HDA tras el diagnóstico: 0,43episodios de HDA por persona-año. Rango del número de sangrados por año individualizados en cada paciente: 0-2,2 episodios al (..) (AU)

Material and methods. We analyzed retrospectively 13 cases of portal cavernoma and estimated the risk of UGB with the Kaplan-Meier survival analysis. We calculated the incidence rate of the sample and the number of haemorrhages per year for each patient individually. From the moment of the diagnosis various parameters were recorded: age, platelets, leukocytes, hemoblobin, hematocrit, prothrombin time and number of bleedings. The relation between these parameters and the risk of bleeding was assessed with the Cox analysis. Results. The patients were followed for a median period of 7.1years. 10 patients (77%) presented at least 1 episode of UGB after the diagnosis. The median survival time until the first haemorrhage was314 days. After the diagnosis the incidence rate of the sample was 0.43episodes of upper gastrointestinal bleeding per person-year. The number of individual bleedings per person had a range of 0 - 2.2 episodesper year. Conclusions. There is very few data about the risk of bleeding in children with portal cavernoma. In our sample, we found out an incidence rate of 0.43 and a median survival time of 314 days until the first (..) (AU)
