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.

[Urachal remnant and acute abdomen: when it's not what it seems].

Among the causes of acute surgical abdomen, infection of a urachal remnant may go unnoticed despite routine complementary studies. We present three cases in boys aged 11, 6, and 4 years who were brought to the emergency department for right iliac fossa pain, fever, and urinary symptoms. Examination and complementary tests results were compatible with acute complicated appendicitis and were sent to surgery. While in the operating room, appendicitis was excluded and inflammatory changes suggestive of infection of the urachal remnant were documented. Complications of urachal remnants should be considered in the differential diagnosis of acute surgical abdomen, since advanced infection of the urachus may be a cause of confusion. A more accurate presumptive diagnosis can change the therapeutic/surgical approach and follow-up.

Remanentes uracales y abdomen agudo: cuando no es lo que parece / Urachal remnant and acute abdomen: when it's not what it seems

Dentro de las causas de abdomen agudo quirúrgico, la infección de un remanente uracal puede pasar desapercibida en cuadros evolucionados a pesar de las pruebas complemetarias habituales.Presentamos tres casos de varones de 11, 6 y 4 años llevados a urgencias por dolor en fosa iliaca derecha, fiebre y síntomas urinarios. La exploración y las pruebas complementarias eran compatibles con patología apendicular aguda evolucionada y fueron intervenidos con dicha sospecha. En el quirófano se descartó apendicitis y se documentaron cambios inflamatorios sugestivos de infección de remanente uracal. Las complicaciones de los remanentes uracales deben ser tenidas en cuenta en el diagnóstico diferencial del abdomen agudo quirúrgico, ya que la infección evolucionada de estos puede confundirnos. Un diagnóstico de presunción más certero puede cambiar nuestra actitud terapéutica, quirúrgica y el seguimiento.(AU)

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.

La mediación tecnológica en la extensión universitaria para la promoción de salud / The technological mediation in the university extension for health promotion

La extensión universitaria, como uno de los procesos formativos de las universidades tiene gran relevancia, razón por la cual en el presente artículo se hace una valoración crítica sobre esta y su manifestación en las universidades cubanas, particularmente con el uso de las tecnologías de la información y las comunicaciones para la promoción de salud. Se concluye que el uso de dichas tecnologías es imprescindible para favorecer el perfeccionamiento de este proceso y, específicamente en la salud, contribuyen a garantizar un diagnóstico certero.

The university extension, as one of the training processes of the universities has great relevance, reason why a critical valuation about it and its manifestation in the Cuban universities is made in this work, particularly with the use of the information and communications technologies for health promotion. It is concluded that the use of these technologies is indispensable to favor the improvement of this process and, specifically in health, they contribute to guarantee a good diagnosis.

Pilas de botón impactadas en esófago: una emergencia quirúrgica potencialmente fatal en la infancia / Impaction of button batteries in the esophagus: a potentially fatal surgical emergency in infancy

Con la reciente popularización de las pilas de botón, ha aumentado la incidencia de casos de niños que las ingieren. A diferencia de otros cuerpos extraños, es más probable que las pilas de botón desarrollen complicaciones graves debido a la posibilidad de lesionar precozmente los tejidos con los que contactan. Se presenta el caso de un niño de 22 meses de edad que ingirió una pila de botón que quedó impactada en esófago cervical. Su retirada por vía endoscópica fue imposible, precisando esofagotomía abierta para su extracción. En el postoperatorio presentó una fístula esófago-cutánea que cerró espontáneamente, y una estenosis esofágica que se resolvió mediante dilataciones endoscópicas con balón. Analizamos las recomendaciones descritas en la literatura reciente contrastándolas con nuestro protocolo de actuación ante ingesta de cuerpos extraños, y se proponen medidas a la industria electrónica para reducir el riesgo de ingestión de pilas de botón en niños pequeños

With the recent popularization of button batteries, the incidence of cases of children who ingest them has risen. Unlike other foreign bodies, button batteries are more likely to develop severe complications due to the possibility of early injury to the tissues in direct contact with them. We present the case of a 22-month-old boy who ingested a button battery which subsequently became lodged in the cervical esophagus. The endoscopic attempt to remove the battery failed, requiring an open esophagotomy for its extraction. In the postoperative period, he presented an esophagocutaneous fistula that closed spontaneously, and an esophageal stricture that was treated successfully with endoscopic balloon dilations. We reviewed the literature analyzing the recommendations recently outlined and contrasted them with our own protocol for management of ingested foreign bodies. In addition, measures aimed at reducing the risk of button battery ingestion in small children are proposed to the electronics manufacturing industry

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.

Un lactante con neumatosis intestinal y neumoperitoneo: la difícil decisión de no intervenir / An infant with intestinal pneumatosis and pneumoperitoneum: the difficult decision not to intervene

El neumoperitoneo en niños puede deberse a causas que no requieran cirugía urgente, como maniobras de reanimación cardiopulmonar, patología respiratoria grave o ventilación mecánica. Intervenir en estos casos podría, incluso, empeorar el pronóstico. Presentamos el caso clínico de un lactante varón, exprematuro, con antecedente al nacer de enterocolitis necrotizante y perforación ileal, que precisó laparotomía y resección intestinal en dos ocasiones y que desarrolló un microcolon por desuso secundario. A los seis meses, tras iniciar alimentación oral exclusiva, presentó distensión abdominal con extensa neumatosis intestinal y neumoperitoneo en las radiografías. Su aspecto era bueno con tránsito intestinal conservado y ausencia de peritonitis. El paciente se mantuvo a dieta absoluta con antibioterapia endovenosa, sondaje nasogástrico y nutrición parenteral. La evolución fue favorable, reiniciando la alimentación oral a los siete días del ingreso. La existencia de un neumoperitoneo no siempre obliga a realizar una laparotomía, y la valoración global del enfermo por un equipo multidisciplinar puede evitar tratamientos agresivos innecesarios

Pneumoperitoneum in children may be due to causes that do not require urgent surgery (cardiopulmonary resuscitation manoeuvres, severe respiratory pathology or mechanical ventilation). Surgery in these cases could even worsen the prognosis. We present the case of a male infant, ex-preterm, with a history of necrotizing enterocolitis and ileal perforation at birth, requiring laparotomy and intestinal resection on two occasions and developing a secondary microcolon, due to disuse. At six months, after transitioning to full oral feeding, he presented abdominal distension with extensive intestinal pneumatosis and pneumoperitoneum on radiographs. His general appearance was good with normal intestinal transit and no peritonitis. The patient remained fasting with intravenous antibiotics, nasogastric decompression and parenteral nutrition. The evolution was favourable with oral feeding restarting on the seventh day of admission. The existence of pneumoperitoneum does not always require a laparotomy and global assessment of the patient by an interdisciplinary health team may avoid unnecessary aggressive treatments
