Role of cellular indices in predicting post-appendectomy abscess in children.

Up to 20% of advanced appendicitis cases can be complicated by postoperative abscesses, adding morbidity and mortality and prolonging hospital stays. This study examines the utility of two cellular indices as predictors of post-appendectomy abscess compared to cell counts. A diagnostic study was conducted on patients <15 years old who underwent appendectomy at a pediatric hospital between 2021 and 2022 (Reg. 2023/390894). Preoperative values of leukocytes, neutrophils, neutrophil-to-lymphocyte ratio (NLR= neutrophils/lymphocytes), and platelet-to-lymphocyte ratio (PLR= platelets/lymphocytes) were compared between patients with post-appendectomy abdominal abscess (PAA) and those without this complication (NPAA). The area under the ROC curve (AUC) was used to establish the predictive capacity of each parameter for PAA. A total of 89 patients with PAA and 93 NPAA children were included.

Derived neutrophil-to-lymphocyte ratio (dNLR) as a diagnostic biomarker of pediatric acute appendicitis.

Appendicitis stands as the most common surgical emergency in pediatric populations. Despite the existence of numerous diagnostic biomarkers, their utility is constrained by limitations in cost-effectiveness, potentially leading to therapeutic delays. This research aims to determine the diagnostic accuracy of the derived neutrophil-to-lymphocyte ratio (dNLR) in appendicitis. Although its role in this context has been recently described, this is the first study to compare its performance against acute-phase reactants routinely employed in clinical practice. Following approval from the Research Committee (2023/390894), a diagnostic study was conducted including patients under 15 years old undergoing surgery for acute appendicitis (AA) and those presenting with non-surgical abdominal pain (AP).

Superior Vesical Fissure as an Incomplete Form of Bladder Exstrophy: A Case Report with Clinico-Pathological Correlation and a Comprehensive Literature Review.

Multiple variants of classic bladder exstrophy have been described, all of them infrequent. Superior vesical fissure is a mild variant of this pathology in which genital involvement is scarce or absent. To date, there are only isolated reports of this entity. We report a full-term female patient of Arabian descent with a clinical and radiological diagnosis of superior vesical fissure that was surgically corrected in our center with a favorable evolution. Histological study, supported by immunohistochemical techniques, showed squamous and transitional epithelium and discrete chronic inflammation. Our literature review identified 26 reports of superior vesical fissure (including ours), with high heterogeneity in terms of clinical characterization and associated malformations and with only two histological reports. The clinical evolution of the patients reported in the literature was favorable, with lower morbidity and mortality than in classical forms of bladder exstrophy.

Antibiotic treatment of post-appendectomy abscesses in children, regardless of size: a twelve years' experience.

Intra-abdominal abscesses are a common issue after appendectomy. Antibiotics have shown efficacy in treating smaller abscesses, while larger ones have traditionally been treated with drainage. This study assesses the efficacy of antibiotics for post-appendectomy intra-abdominal abscess (PAA) in children regardless of size. Case-control study of children with PAA admitted at our hospital from 2010 to 2022. The efficacy of antibiotics was compared between abscesses less and more than 6 cm in diameter. The Institutional Review Board has approved this study. A total of 1766 appendectomies were performed from 2010 to 2022 with an incidence of PAA of 5% (n = 89): age 9.3 IQR 5.8, 63% male (n = 56). Sixty-seven patients presented with a ≤ 6 cm abscess (controls) and 22 children had a > 6 cm PAA (cases). Length of intravenous antibiotics were higher in cases (15 IQR 7 days) than controls (12 IQR 4 days), p = 0.003. The efficacy of antibiotics in controls was 97% whereas 86.4% in cases (p = 0.094), reoperation was needed in 2/67 controls and 3/22 cases, with no differences in complications or readmission. The length of stay was longer in cases (15 IQR 6 days) than controls (13 IQR 5 days), p = 0.042. Antibiotics seem a safe treatment for PAA in children regardless of the size. However, this approach is associated with a longer period of intravenous antibiotics and hospital stay, although not with a higher rate of therapeutic failure, complications or reoperations.

Unusual radiological finding in foreign bodies ingestion: three esophageal coins / Hallazgo radiológico inusual en ingesta de cuerpos extraños: tres monedas esofágicas

Abstract Case description: A 5-year-old girl presented to the emergency department with a history of foreign body ingestion. A cervico-thoracoabdominal radiograph demonstrate a foreign body in the esophagus, which seemed to show a double rim sign suspecting a button battery. After an emetic episode and expelling a coin, the child became asymptomatic. Close inspection of the X-ray demonstrated that the image was formed by superimposition of 3 circumferential objects of different sizes. Another X-ray observed the persistence of two superimposed objects. Clinical findings: The girl presented with sialorrhea, odynophagia, and nausea. Vital signs and physical examination were normal. There was no significant medical history. Treatment and Outcome: With the suspicion of multiple impacted esophageal objects, the patient was then taken to the operating room. During the flexible esophagoscopy 2 coins were found in the esophagus, both were removed without difficulty. The patient had an uneventful postoperative recovery and there have been no long-term complications. Clinical relevance: Unusual radiographic findings regarding esophageal foreign bodies have been reported, however, we describe the first case of a child with 3 coins impacted in the esophagus and a new radiological finding in foreign bodies ingestions that allow to avoid misdiagnosis and improve outcomes.

Resumen Descripción del caso: Una niña de 5 años es llevada a urgencias tras la ingesta de un cuerpo extraño. La radiografía cérvico-toraco-abdominal evidenció un cuerpo extraño esofágico con signo de doble halo, lo que hizo sospechar una pila de botón. Tras un vómito con expulsión de una moneda los síntomas desaparecieron. Una inspección minuciosa de la radiografía demostró que la imagen estaba formada por la superposición de 3 objetos circunferenciales de diferentes tamaños. Una nueva radiografía mostró persistencia de dos objetos superpuestos. Hallazgos clínicos: La niña refería odinofagia, náuseas y tenía sialorrea. Los signos vitales y el examen físico eran normales. No tenía antecedentes médicos relevantes. Tratamiento y desenlace: Con la sospecha de impactación esofágica múltiple, la paciente fue llevada al quirófano. Durante la esofagoscopia se encontraron 2 monedas en el esófago que fueron extraídas sin dificultad. La evolución postoperatoria fue favorable y no hubo complicaciones a largo plazo. Relevancia clínica: Aunque se han reportado hallazgos radiográficos inusuales en cuerpos extraños esofágicos, describimos el primer caso de un niño con 3 monedas impactadas en el esófago y un nuevo hallazgo radiológico en la ingesta de cuerpos extraños que permite evitar diagnósticos erróneos y mejorar los desenlaces.

Intravesical Oxybutynin for Urgent Bladder Rescue in a Newborn with Posterior Urethral Valves.

Posterior urethral valves are the most common cause of bladder outlet obstruction in male newborns. Initial catheter drainage alleviates the urethral obstruction before definitive management by valve ablation. Newborns with posterior urethral valves often present with hypercontractile bladders that may inhibit upper tract drainage despite bladder catheterization. Anticholinergic agents are commonly used to treat detrusor hyperactivity, with oxybutynin being the most commonly used. We report the first case of a newborn with posterior urethral valves and ureterovesical junction obstruction caused by detrusor hypertrophy who underwent urgent intravesical instillation of oxybutynin at high doses in an attempt to avoid a diversion procedure.

Colocación de sondas de pHmetría mediante fórmula relacionada con la talla. ¿Es un método aplicable a los adultos? / Placement of pH-monitoring probes using height-related formulas. Is it an applicable method to adults?

INTRODUCCIÓN: La pHmetría esofágica permite cuantificar los episodios de reflujo ácido en pacientes con enfermedad por reflujo gastroesofágico (ERGE). El posicionamiento adecuado del electrodo de pH a 5 cm por encima del esfínter esofágico inferior (EEI), determina la precisión de la prueba. La manera más exacta para localizar el EEI es mediante su determinación previa por manometría esofágica, pero es una técnica molesta, por lo que en niños tendemos a utilizar fórmulas matemáticas. OBJETIVOS: Valorar la aplicabilidad de las fórmulas pediátricas de estimación de longitud esofágica en pacientes adultos y su repercusión en la precisión diagnóstica. MATERIAL Y MÉTODOS: Estudio prospectivo en pacientes adultos en el que la distancia desde el borde de la narina hasta el EEI determinada por manometría se ha comparado con la distancia estimada en relación a la talla calculada por 4 fórmulas pediátricas (numeradas del 1 al 4). También hemos valorado la relación entre posición de la sonda y porcentaje de reflujos detectados en nuestra serie de impedanciometría. RESULTADOS: La fórmula 1 (9,31 + talla cm × 0,197) fue la más precisa (comparación de medias −0,38 con IC 95% −0,70 a −0,06, p = 0,019). Con dicha fórmula, ningún paciente presentó errores de estimación de ± 6 cm. Con las fórmulas 2, 3 y 4 el porcentaje de error fue del 4,4, del 1,5 y del 32,0%, respectivamente. CONCLUSIÓN: La estimación de la longitud del esófago en adultos mediante la fórmula 1 es aceptable y puede usarse en casos en los que el paciente rechace la realización de una manometría previa

INTRODUCTION: Oesophageal pH-monitoring allows the quantification of gastric reflux episodes in patients with gastroesophageal reflux disease (GERD). The accuracy of the test depends on correct positioning of the pH sensor 5 cm above the lower oesophageal sphincter (LES). The most precise manner to locate the LES is through prior determination by oesophageal manometry. However, because this technique is uncomfortable, mathematical formulas tend to be used in children. OBJECTIVES: To evaluate the applicability of paediatric formulas to estimate oesophageal length in adults and their effect on diagnostic accuracy. MATERIAL AND METHODS: A prospective study was carried out in adult patients, in whom the distance between the nasal orifice and the LES was determined by manometry and was compared with the estimated height-related distance calculated by four paediatric formulas (numbered 1 to 4). We also evaluated the relationship between the position of the probe and the percentage of reflux detected in our series of impedance measurements. RESULTS: Formula 1 (9.31 + height in cm × 0.197) was the most accurate (comparison of means −0.38 with 95% CI −0.70/−0.06, P = .019). With this formula, none of the patients had estimation errors of ± 6 cm. With formulas 2, 3 and 4, the percentage of error was 4.4%, 1.5% and 32.0%, respectively. CONCLUSION: Oesophageal length estimation in adults by using formula 1 is acceptable and can be used in adult patients who refuse to undergo prior manometry
