Enfermedad inflamatoria intestinal en el embarazo: peculiaridades y tratamiento. Revisión bibliográfica / Inflammatory bowel disease in pregnancy: peculiarities and treatment. Review

Resumen ANTECEDENTES: La prevalencia de la enfermedad inflamatoria intestinal en países occidentales se estima en 0.7%. Su relación con el embarazo está en constante estudio y actualización. Esta enfermedad se relaciona con diferentes afecciones obstétricas: prematurez y aumento de teratogenia. La atención médica y el tratamiento suponen un reto durante el embarazo. OBJETIVO: Actualizar los conocimientos acerca de cómo el embarazo modifica el curso de la enfermedad y cómo la enfermedad modifica el curso de aquél, mencionar la seguridad de los tratamientos a las embarazadas y los consensos obstétricos vigentes. METODOLOGÍA: Revisión bibliográfica efectuada en dos bases de datos (PubMed y Embase) con los siguientes criterios de búsqueda (MeSH): "inflammatory bowel disease'' y "pregnancy'' de artículos publicados entre el 2015 y diciembre del 2022, escritos en todas las lenguas: metanálisis, ensayos clínicos, revisiones sistemáticas, narrativas, estudios prospectivos y retrospectivos. RESULTADOS: Se identificaron 345 registros, que luego de la eliminación de los duplicados y otras causas se seleccionaron 30 artículos por su relevancia y novedad. CONCLUSIÓN: La paciente con enfermedad inflamatoria intestinal, en estado de embarazo, debe considerarse de alto riesgo y requerimiento de seguimiento estrecho. La planificación del embarazo es decisiva a fin de optimizar el grado de actividad de la enfermedad y aminorar sus complicaciones. Si bien la mayor parte de los fármacos para su tratamiento se consideran seguros es necesario conocerlos en profundidad.

Abstract BACKGROUND: The prevalence of inflammatory bowel disease is estimated to be 0.7% in western countries. Its association with pregnancy is constantly being studied and updated. This disease is associated with several obstetric conditions: prematurity or increased teratogenicity. Medical care and treatment during pregnancy is a challenge. OBJECTIVE: To update the knowledge on how pregnancy modifies the course of the disease and how the disease modifies the course of the disease, to mention the safety of treatments for pregnant women and the current obstetric consensus. METHOD: Literature search in two databases (PubMed and Embase) with the following search criteria (MeSH): "inflammatory bowel disease" and "pregnancy" of articles published between 2015 and December 2022, written in all languages: meta-analyses, clinical trials, systematic reviews, narratives, prospective and retrospective studies. RESULTS: 345 records were identified and, after elimination of duplicates and other causes, 30 articles were selected for relevance and novelty. CONCLUSION: The pregnant patient with inflammatory bowel disease should be considered high risk and require close follow-up. Pregnancy planning is essential to optimise disease activity and minimise complications. Although most drugs used to treat inflammatory bowel disease.

Epilepsia y embarazo: particularidades y tratamiento / Epilepsy and pregnancy: particularities and treatment

Resumen ANTECEDENTES: La prevalencia de epilepsia en mujeres embarazadas es del 0.3 al 0.5%. Si bien es una enfermedad de baja frecuencia es importante saber cómo el embarazo modifica el curso de la enfermedad y cómo la enfermedad modifica el curso del embarazo y cuál es la seguridad de los tratamientos durante el embarazo y cuáles son los consensos obstétricos actuales a este respecto. OBJETIVO: Actualizar los conocimientos acerca de cómo el embarazo modifica el curso de la enfermedad, cómo la enfermedad modifica el curso del embarazo, cuán seguros son los tratamientos durante el embarazo y los consensos obstétricos actuales a este respecto. METODOLOGÍA: Revisión bibliográfica efectuada en dos bases de datos (PubMed y Scopus) con los siguientes criterios de búsqueda (MeSH): "epilepsy'' y "pregnancy'' de artículos publicados entre el 2015 y mayo del 2022, escritos en inglés o español: metanálisis, revisiones sistemáticas, narrativas o ensayos clínicos. RESULTADOS: Se identificaron 310 registros. Después de la eliminación por duplicación y otras causas se seleccionaron 20 artículos, más otros utilizados como complemento del tema. CONCLUSIONES: El embarazo de una paciente con epilepsia debe considerarse de alto riesgo y, por lo tanto, adecuar su seguimiento. La planificación del embarazo resulta fundamental, con el propósito de indicar el tratamiento antiepiléptico adecuado y el suplemento con ácido fólico, si es necesario.

Abstract BACKGROUND: The prevalence of epilepsy in pregnant women is 0.3 to 0.5%. Although it is a low frequency disease, it is important to know how pregnancy modifies the course of the disease and how the disease modifies the course of pregnancy and what is the safety of treatments during pregnancy and what are the current obstetric consensuses in this regard. OBJECTIVE: To update knowledge about how pregnancy modifies the course of the disease, how the disease modifies the course of pregnancy, how safe are the treatments during pregnancy and the current obstetric consensus in this respect. METHODOLOGY: Literature review conducted in two databases (PubMed and Scopus) with the following search criteria (MeSH): "epilepsy" and "pregnancy" of articles published between 2015 and May 2022, written in English or Spanish: meta-analyses, systematic reviews, narratives or clinical trials. RESULTS: 310 records were identified. After elimination for duplication and other causes, 20 articles were selected, plus others used to complement the topic. CONCLUSIONS: Pregnancy in a patient with epilepsy should be considered high risk and therefore follow-up should be appropriate. Pregnancy planning is essential in order to indicate the appropriate antiepileptic treatment and folic acid supplementation, if necessary.

Hemoperitoneo espontáneo asociado con endometriosis en gestante de segundo trimestre / Spontaneus hemoperitoneum associated with endometriosis in a second trimester pregnant woman

Resumen ANTECEDENTES: El hemoperitoneo espontáneo es una complicación infrecuente durante la gestación (1 de cada 100,000 embarazos) con importante repercusión en la morbilidad y mortalidad materno-fetal. CASO CLÍNICO: Paciente de 44 años, con 21+6 semanas de embarazo, con diagnóstico previo al embarazo de endometriosis, que acudió a Urgencias debido a un dolor abdominal. Después de comprobar la viabilidad fetal, se solicitó una ecografía abdominal-pélvica urgente en la que se visualizó líquido libre en la fosa de Morrison, periesplénico y perihepático. Durante su estancia en Urgencias sufrió una anemización aguda acompañada de inestabilidad hemodinámica; se decidió una laparotomía exploradora urgente. Entre los hallazgos operatorios destacó el hemoperitoneo de 1.5 litros y de sangrado en torno del anejo derecho y el parametrio. En el control ecográfico a las 12 horas de la intervención se comprobó la ausencia del latido fetal; a las 72 horas se registró la expulsión espontánea del feto. La evolución de la paciente fue favorable por lo que se dio de alta a los 10 días de la intervención. CONCLUSIONES: Si bien durante el embarazo no hay forma de anticipar las complicaciones de la endometriosis preexistente, es importante, en caso de dolor abdominal intenso, sospechar otros eventos raros que potencialmente puedan ser mortales.

Abstract BACKGROUND: Spontaneous hemoperitoneum is a rare complication in pregnancy (1 in 100.000 pregnancies) with a great impact on maternal and fetal morbidity and mortality. CLINICAL CASE: A 44-year-old woman, 21+6 weeks pregnant, with a diagnosis of endometriosis, who went to the Emergency Department due to abdominal pain. After verifying fetal viability, an urgent abdominal ultrasound was requested in which free fluid was visualized at the level of Morrison's fossa, perisplenic and perihepatic. During her stay in the Emergency Department, she developed acute anemia accompanied by hemodynamic instability, for which an urgent exploratory laparotomy was performed. Among the operative findings, the presence of hemoperitoneum of 1,5 liters and bleeding at the level of the right adnexa and parametrium stood out. In ultrasound control 12 hours after the intervention, the absence of a fetal heartbeat was verified producing the spontaneuous expulsion of the fetus at 72 hours. Subsequently, the patient's evolution was favorable, and she was discharged 10 days after the intervention. CONCLUSION: Although during pregnancy there is no way to anticipate the occurrence of complications from pre-existing endometriosis. It is important the severe abdominal pain occurs, to suspect rare but life-threatening events.

Sonochemical degradation of neonicotinoid pesticides in natural surface waters. Influence of operational and environmental conditions.

Neonicotinoids sonochemical oxidation at high-frequency ultrasound (MHz range) has been carried out in ultrapure and natural surface-water matrices (river, reservoir and wastewater treatment plant effluent). To evaluate the influence of the operating variables, that is initial pollutant concentration, ultrasound frequency, ultrasound power, and pulse-stop time a Box-Behnken experimental design was planned. Optimal results were obtained using a frequency of 578 kHz, a power of 40 W L-1, with a pollutant concentration of 1 µM (for each pesticide), and using a pulse-stop time of 100 ms. The experimental data adjustment using the Langmuir-Hinshelwood heterogeneous kinetic model showed that neonicotinoids oxidation was carried out in the bubble-liquid interface by the attack of hydroxyl radicals. Experiments performed in the presence of radical scavengers, that is, methanol, ethanol and tert-butyl alcohol corroborated this reaction mechanism. The influence of some environmental conditions such as pH, presence of soluble inorganic species (Cl-, SO42-, NO3-, HPO42-, HCO3-) and soluble organic species (humic acids content) were established. Finally, the aqueous matrix's influence was investigated for three natural surface water cases, and the results were rationalized according to the main water physicochemical characteristics.

Angioedema hereditario tipo III en una embarazada: a propósito de un caso / Hereditary angioedema type III in pregnant women: case report and literature review

Resumen ANTECEDENTES: El angioedema hereditario es una enfermedad rara, caracterizada por episodios recurrentes de edema en cualquier parte del cuerpo, sobre todo en las extremidades, la cara y las vías respiratorias. Existen tres tipos de enfermedad en función de su causa, el menos frecuente es el III con un nivel y función del inhibidor de C1 normales. Su fisiopatología es poco conocida; por lo tanto, su diagnóstico es difícil. Su tratamiento ha avanzado en los últimos años, aunque queda mucho por definir, sobre todo durante el embarazo. OBJETIVO: Evaluar la bibliografía disponible relacionada con el angioedema hereditario y su atención médica en mujeres embarazadas. CASO CLÍNICO: Paciente de 30 años, en curso de su primer embarazo. El único antecedente personal destacable fue haber padecido angioedema hereditario tipo III, diagnosticado 10 años antes después de varios episodios de angioedema orofacial. A lo largo del embarazo sobrevinieron varias crisis de la enfermedad que requirieron tratamiento de los episodios agudos y de mantenimiento en el tercer trimestre. Por último, ocurrió un parto instrumentado mediante vaccum, por riesgo de pérdida de bienestar fetal con buen desenlace materno y fetal en el posparto inmediato. CONCLUSIONES: El angioedema hereditario tipo III es una enfermedad muy rara y poco conocida en la Ginecoobstetricia que requiere establecer un protocolo y estandarización de la atención clínica, sobre todo en las embarazadas, lo que ayudará a proporcionar una información y asistencia de calidad a estas pacientes.

Abstract BACKGROUND: Hereditary angioedema is a rare disease characterized by recurrent episodes of edema anywhere in the body, especially in the extremities, face and airways. There are three types of the disease depending on its cause, the most infrequent being III with normal C1 inhibitor level and function. Its pathophysiology is poorly understood; therefore, its diagnosis is difficult. Its treatment has advanced in recent years, although much remains to be defined, especially during pregnancy. OBJECTIVE: To evaluate the available literature related to hereditary angioedema and its medical care in pregnant women. CLINICAL CASE: 30-year-old female patient, during her first pregnancy. The only personal history of note was hereditary angioedema type III, diagnosed 10 years earlier after several episodes of orofacial angioedema. Throughout the pregnancy, several crises of the disease occurred, requiring treatment in acute episodes and maintenance treatment in the third trimester. Finally, one delivery was instrumented by vaccum, due to risk of loss of fetal well-being with good maternal and fetal outcome in the immediate postpartum period. CONCLUSIONS: Hereditary angioedema type III is a very rare and little-known disease that requires establishing a protocol and standardization of clinical care, especially in pregnant women, which will help to provide quality information and assistance to these patients.

Breast metastasis from medullary thyroid carcinoma mimicking ductal carcinoma with neuroendocrine differentiation.

BACKGROUND: Medullary thyroid carcinoma very rarely metastasizes to the breast. Hematogenous spread to the liver, lungs, or mediastinum is more common. CASE: We describe the morphologic and immunohistochemical features of a 63-year-old woman who presented with a BIRADS-5 category nodule in the right breast and enlarged axillary lymph nodes. Core biopsy showed suggested breast cancer with neuroendocrine or apocrine differentiation. The immunohistochemical profile showed (RE-/RP-/HER-2-) and Ki67 10%. Chromogranin and synaptophysin were positive; AR and GCDFP-15 were negative. On reviewing the patient's clinical history, it was discovered that she had been treated for medullary thyroid carcinoma 15 years earlier. Additional stains showed positivity for TTF-1, CEA, and calcitonin. These findings were consistent with a diagnosis of breast metastasis from medullary thyroid carcinoma. We discuss briefly the morphologic features and the possible key features in order to make an accurate diagnosis. CONCLUSION: This case highlights the importance of investigating a history of cancer in patients with discordant or unusual histologic or immunohistochemical findings, as this can help avoid misdiagnosis and inappropriate treatment.

Úlcera de Lipschütz: reporte de un caso y revisión bibliográfica / Lipschütz Ulcer: a case report and a literature review

Resumen: ANTECEDENTES: Las úlceras de Lipschütz son lesiones vulvovaginales dolorosas, de aparición aguda y desaparición espontánea en 2 a 6 semanas, no dejan secuelas ni son recurrentes a largo plazo. Su etiopatogenia es incierta, alrededor de 70% se consideran idiopáticas. En los estudios más recientes se ha demostrado su asociación con agentes infecciosos, sobre todo con el virus de Epstein-Barr. El diagnóstico se establece por exclusión y su tratamiento se basa en el control sintomático, cicatrizantes, analgésicos y antisépticos. CASO CLÍNICO: Paciente de 15 años, con úlceras vulvares de aparición súbita acompañadas de cuadro catarral. Se indicó tratamiento local con cicatrizante, antiséptico y antiinflamatorio; al cabo de tres semanas se observó la desaparición de las lesiones y la negatividad de las pruebas que descartó el origen infeccioso. Se estableció el diagnóstico de úlcera de Lipschütz. CONCLUSIONES: La úlcera de Lipschütz es infrecuente y los niños son quienes más la padecen. Debido al carácter de desaparición espontánea y a la juventud de las pacientes, es decisivo establecer el correcto diagnóstico diferencial.

Abstract: BACKGROUND: Lipschütz Ulcers are painful, acute onset and self-limiting vulvovaginal lesions that can frequently be associated with prodromal symptoms, disappearing in 2-6 weeks without any sequelae. 70% of cases present idiopathic etiopathogenesis, and are related to Epstein-Barr virus, among others. The diagnosis is made by exclusion and its treatment is based on symptomatic control and the promotion of correct healing, using analgesics, cicatrizers and antiseptics. CASE REPORT: A 15-year-old girl reported the acute apparition of ulcerative vulvar lesions coinciding with systemic catarrhal symptoms. Local treatment with healing, antiseptic and anti-inflammatory lotions was prescribed, and after three weeks, she was reevaluated, observing the disappearance of the lesions and the negativity of the tests to rule out infectious origin, for which she was diagnosed with a Lipschütz ulcer. CONCLUSIONS: Lipschütz ulcer is rare and children are the ones who suffer most from it. Due to the spontaneous disappearance character and the youthfulness of the patients, it is decisive to establish the correct differential diagnosis.

[Effect of a Physical activity program on self-esteem in subjects with chronic diseases. 'Pas a Pas' community intervention trial]. / Efecto de un Programa de actividad física sobre la autoestima en sujetos con enfermedades crónicas. Ensayo de intervención comunitaria «Pas a Pas¼.

AIM: To evaluate the effectiveness of a 9 months of supervised Physical Activity (PA) Program with sociocultural activities, on self-esteem and its association on the control of chronic diseases in adult primary care users. DESIGN: Multicenter, randomized, controlled community intervention. LOCATION: 4 Primary care centers in Reus-Tarragona, Spain. PARTICIPANTS: 364 subjects, randomized to the Control Group (CG=104) and Intervention Group (IG=260). INTERVENTION: Supervised walking program of 120min/week with sociocultural activities once a month. MAIN MEASUREMENTS: At baseline and at post-intervention we assessed: PA (IPAQ-S), self-esteem (Rosenberg scale) and cardiovascular indicators: smoking, systolic (SBP) and diastolic (DBP) blood pressure, serum LDL and HDL cholesterol, and serum glucose. Sociodemographic characteristics and diagnostic of chronic diseases are recorded. RESULTS: The Program increased the PA in the IG (P=.001), while it decreased in the CG (P=.002), and also the self-esteem in the group of participants (1.28 points, P=.006) and in the groups with diagnoses of hypertension (1.60 points, P=.005), dyslipidemia (1.62 points, P=.012), excess weight (1.24 points, P=.011) or anxiety/depression (1.53 points, P=.045), assessed by multivariate statistical models. The increase in self-esteem during the intervention decreased SBP -0.5mmHg (P=.030) in the hypertension group, regardless of baseline SBP and the effect of the intervention. CONCLUSION: The PA program increased the PA and self-esteem in adult primary care users. The increase of self-esteem improved the control of SBP in hypertensive patients.

Assembly of Conducting Polymer and Biohydrogel for the Release and Real-Time Monitoring of Vitamin K3.

In this work, we report the design and fabrication of a dual-function integrated system to monitor, in real time, the release of previously loaded 2-methyl-1,4-naphthoquinone (MeNQ), also named vitamin K3. The newly developed system consists of poly(3,4-ethylenedioxythiophene) (PEDOT) nanoparticles, which were embedded into a poly-γ-glutamic acid (γ-PGA) biohydrogel during the gelling reaction between the biopolymer chains and the cross-linker, cystamine. After this, agglomerates of PEDOT nanoparticles homogeneously dispersed inside the biohydrogel were used as polymerization nuclei for the in situ anodic synthesis of poly(hydroxymethyl-3,4-ethylenedioxythiophene) in aqueous solution. After characterization of the resulting flexible electrode composites, their ability to load and release MeNQ was proven and monitored. Specifically, loaded MeNQ molecules, which organized in shells around PEDOT nanoparticles agglomerates when the drug was simply added to the initial gelling solution, were progressively released to a physiological medium. The latter process was successfully monitored using an electrode composite through differential pulse voltammetry. The fabrication of electroactive flexible biohydrogels for real-time release monitoring opens new opportunities for theranostic therapeutic approaches.

Portal Cavernoma in the Era of Mesoportal Shunt (Rex) and Liver Transplant in Children.

OBJECTIVE: The mesoportal shunt (MPS) and liver transplantation (LT) have changed the scenario of extrahepatic portal vein obstruction (EHPVO) since the MPS, the only "curative" technique, can now be offered in asymptomatic patients and also thrombotic complications of LT have increased the incidence of EHPVO. MATERIAL AND METHODS: A retrospective study of patients undergoing surgery for EHPVO was conducted between 1990 and 2015. An analysis was done for the shunt permeability and clinical evolution over time. RESULTS: Of the 73 children with EHPVO, 39 were operated (12 posttransplant and 27 idiopathic). The median age at surgery was 9.36 years (range, 1.60-17.42 years). The MPS was the technique of choice; it was offered in 21 patients but eventually could be performed in only 18 (9 posttransplant and 9 idiopathic). The results of MPS were better in idiopathic (just one thrombosis successfully converted into mesocaval bypass). In the MPS after LT (n = 9), six shunts are permeable, two became thrombotic (one patient requiring retransplantation), and one late thrombosis occurred and the patient died eventually because of gastrointestinal bleeding. In the remaining patients (21 out of the 39), MPS was not performed because of intrahepatic cavernoma, portal vein hypoplasia, or insufficient length of vascular graft (especially in left lateral segment graft LT, since the portal vein is usually located in the right upper quadrant). They underwent 10 distal splenorenal shunts (DSRS) (1 posttransplant and 9 idiopathic), 5 proximal splenorenal shunts (PSRS) (1/4), 6 mesocaval shunts (1/5), and 1 modified Sugiura procedure. The results with DSRS have been favorable (one thrombosis, converted into mesocaval bypass). In the PSRS no thrombosis was identified and in the mesocaval shunt one early thrombosis occurred. Posttransplantation group had higher risk of shunt thrombosis, regardless of the surgical technique (chi-square, 0.021). The total increase of platelets after 6 months was not different in MPS as compared with other surgical techniques (analysis of variance, 0.110). CONCLUSIONS: The MPS is the technique of choice in EHPVO for idiopathic thrombosis as well as secondary to LT. Not all cases are favorable for MPS, so the surgeon must consider the possibility of alternative techniques for EHPVO. The results in terms of shunt patency are much better in idiopathic cavernoma that posttransplant patients.

Emisores políticos, mediáticos y ciudadanos en internet: hacia un nuevo marco comunicativo en la jornada de reflexión en España / Political broadcasting, the media and citizens on the Internet: towards a new communication milestone for the day of reflection in Spain

Resumen La campaña electoral en España está regulada por la ley orgánica de régimen electoral general 5/1985, que no contempla ninguna medida específica para la cibercampaña. Este vacío legal motiva a los emisores a realizar una interpretación de la norma cuando se comunican en internet durante este periodo. Con el fin de explorar si el nuevo tempo y forma de comunicación en internet se corresponde con un nuevo espacio comunicativo, este estudio analiza los mensajes que políticos, periodistas y ciudadanos se intercambiaron en la jornada de reflexión de las últimas elecciones generales españolas (2011) y muestra cómo esta jornada, comprendida hasta la fecha como un día de reflexión silenciosa, cobra un nuevo sentido en internet.

Abstract Electoral campaigns in Spain are governed by Organic Law 5/1985 on the general election system, which does not include any specific measures on cybercampaigns. This legal vacuum has led the media to come up with their own interpretion of the regulations when engaging in Internet communications during this period. In order to explore whether the new speed and style of communicating by Internet is matched by a new communication space, this article analyzes the messages that politicians, journalists and citizens exchanged during the day of reflection in Spain’s last general election (2011), showing how what has, until now, been seen as a day of silent reflection takes on a new meaning with the Internet.

Severe tracheobronchial injuries: our experience.

INTRODUCTION: Severe tracheobronchial injuries (TBI) in children are usually traumatic or iatrogenic. However, they can also be caused by mediastinal infections that lead to critical situations. We herein report our experience in the treatment of these lesions. METHODS: A retrospective study was conducted for patients treated at our center from 2008 to 2014. TBI was diagnosed by imaging studies and bronchoscopy. Treatment was initially conservative (drainage of air and secretions, mechanical ventilation with minimal pressures, and an early extubation) with a limited use of surgical procedures whenever necessary. RESULTS: A total of 10 patients (7 males and 3 females) with a median age of 7.5 years (range, 3-17 years) suffered TBI. The mechanism was traumatic in six (three accidental and three iatrogenic) and mediastinal infection in four (three mycotic and one bacterial abscesses). All traumatic cases responded to conservative measures, except one iatrogenic lesion, which was surgically repaired. There were no complications or residual damages. Two patients with mediastinal infection presented with sudden cardiorespiratory arrest, one with hemoptysis caused by an arteriotracheal fistula and the other because of carinal rupture. Both died before any therapeutic measures could be taken. The other two patients were treated, one with previous extracorporeal membrane oxygenation support, underwent arterial embolization, but ultimately died, and the other one survived, but required esophagectomy and creation of a thoracostome for secondary wound closure of the bronchocutaneous fistula. CONCLUSION: Conservative treatment with gentle respiratory support suffices in most traumatic cases of TBI. Infectious abscesses with involvement of adjacent structures sometimes require complex surgery and are life-threatening.

Ulcerative ileitis after proctocolectomy in children: a complication of ulcerative colitis or a disease in itself after ileoanal pullthrough?

Ulcerative ileitis (UI) after restorative proctocolectomy (RPC) and ileoanal pullthrough procedure (IAPP) is a rare condition described as inflammation of the terminal ileum proximal to the anastomosis. It is mostly observed in ulcerative colitis (UC) and is designated as prepouch ileitis; sometimes with pouchitis, but not necessarily all the time. Its incidence in adults is less than 5%, but the information in children is limited. Pathogenesis is unknown, it has been considered as a disease by itself, independently on the underlying disease. It involves additional morbidity and impacts negatively on quality of life because there is no effective treatment so far. This study aims to review the cases of UI in our institution and to summarize their clinical features and management. A descriptive retrospective study of UI patients between 1990 and 2013 was conducted. Children with RPC and IAPP with clinical and pathological diagnosis of UI were included. Sociodemographic and clinical data, diagnostic, and therapeutic procedures were collected through medical records. UI was diagnosed in eight patients (six males) after RCP; four had UC, two had total colonic aganglionosis (TCA), and two had complex anorectal malformations (one cloacal exstrophy and one omphalopagus twin with bladder exstrophy). Different surgical techniques were used in each case: UC patients underwent IAPP, 50% with J-reservoir and 50% without it; posterior sagittal pullthrough was performed in those with anorectal malformations; one Soave and one Swenson procedure in those with TCA. In summary, three patients had reservoir and five did not. The median age at the IAPP and ostomy closure was 6 years (range 2 months-8 years) and 7 years (range 6 months-9 years), respectively. UI was found after a median of 23 months (range 1-48 months), all of them after digestive tract continuity was reestablished. The leading symptom was lower GI or gastrointestinal, both of them bleeding with abdominal pain, followed by abdominopelvic abscesses and malabsorption with weight loss. Pathology showed nonspecific inflammatory changes. Treatment included antibiotics, corticosteroids and/or immunosuppressive agents with variable response, requiring a new ileostomy in five cases. Ileitis disappeared after diversion. In our experience, UI after colectomy is not an exclusive feature of UC as has been previously described. Although it appears with pouchitis, the presence of a reservoir is not a must, suggesting that this is a different entity. No medical treatment has been really effective in our patients and diversion above this level stopped the process. Further studies on its pathogenesis and treatment strategies are necessary.

Tertiary surgery for complicated repair of esophageal atresia.

AIM: The ideal repair of esophageal atresia (EA) is primary anastomosis with closure of the fistula if present. Long gap or local circumstances prompt other procedures that occasionally lead to disastrous complications. The aim of this study was to analyze the management of these complications in a tertiary referral center. PATIENTS AND METHODS: A retrospective review of patients treated for EA between 1993 and 2013 was conducted. Both the patients were primarily treated by us, and referrals from elsewhere after two or more failed operations were included. RESULTS: In total, 23 patients were included (3/176 cases of EA treated primarily by us and 20 referrals). Of the 23 patients, 6 had type I EA, 15 type III (four long gaps), 1 type IV, and 1 type V. Cardiac anomalies were associated in seven cases, duodenal atresia in three, and Down syndrome in two patients. Primary anastomosis was initially achieved in 12 patients. Primary or secondary Foker lengthening was used in seven cases. The causes of the failure were anastomotic leaks in nine, unmanageable strictures in seven, and refistulization in five patients. These patients required 66 reoperations (median of 3 [2-7]) before inclusion in the study. Radical tertiary treatment consisted of 15 esophageal replacements (11 colonic grafts and 4 gastric pull-ups), and 1 esophageal-gastric disconnection. Five patients previously treated with esophageal replacement and referred for graft problems required 13 interventions. Two families did not give consent for one replacement and one disconnection. Complications appeared in 12 patients, and 9 additional operations were required in 7 patients. With a follow-up of 31 months (range, 4-139 months) 15 patients take all their meals per os, 5 occasionally use the gastrostomy, and 2 and 1 are fed exclusively via gastrostomy or jejunostomy. All tracheoesophageal fistulas were closed, but 15 cases are below p3 for weight and 12 for height. Three patients (13%) ultimately died 32 months (range, 9-56 months) after the first operation (due to aspiration in one, and for causes unrelated to it in the other two [tracheostomy obstruction and Guillain-Barré syndrome]). CONCLUSIONS: When repeated complications appear after EA repair, radical surgical attitudes may be justified. If esophageal continuity cannot be reestablished, the native esophagus may have to be discarded and replaced. Many complications should be expected, but the end result can be good. These patients should be referred to centers with large experience in the management of this complex condition.

Early endoscopic dilation and mitomycin application in the treatment of acquired tracheal stenosis.

INTRODUCTION: Acquired airway stenosis is a common complication in children after periods of tracheal intubation. We reviewed our experience in the endoscopic treatment of these lesions. PATIENTS AND METHODS: We performed a retrospective review of patients who presented acquired tracheal-subglottic stenosis (SGS) treated at our center from 2005 to 2012. We reviewed the etiology, age, clinical presentation, methods of diagnosis, number of bronchoscopies, angioplasty balloon dilations performed, and long-term results. RESULTS: A total of 18 patients (13 M, 5 F) were treated at our institution between 2005 and 2012. Median age at treatment was 3.5 months (range, 1-96 months). Of the 18 children, 16 children had SGS (all cases were postintubation), and 2 children presented tracheal stenosis (1 postintubation, 1 after tracheal surgery). Median intubation time was 30 days (range, 3-120 days). Extubation failure and stridor were the main clinical features. SGS were diagnosed as grade I in three patients, grade II in nine patients, and grade III in six patients. Bronchoscopy allowed diagnostic in all cases, and was followed by angioplasty balloon dilation, with a median of 2.5 (range, 1-5) sessions. In SGS grade I, the relation patient/number of dilations was 1; in SGS grade II 2.6, and in SGS grade III 3.5. Mitomycin was applied in 15 patients. No patients presented intraoperative complications or required reoperation. Median follow-up time was 36 months (range, 5-72 months) and no recurrence was noticed. CONCLUSIONS: Early endoscopic dilation with balloon shows as an effective and safe treatment in acquired tracheal and SGS.

Failed Nissen fundoplication in children: causes and management.

INTRODUCTION: Nissen fundoplication (NF) is the gold standard procedure for the treatment of gastroesophageal reflux (GER) in children. However, it fails in a significant proportion of patients. The purpose of this study was to identify preoperative predictors of failure and to examine the results of reoperations. PATIENTS AND METHODS: The charts of patients who underwent NF at our institution between 1992 and 2011 were retrospectively reviewed. Surgery was indicated in patients with symptomatic GER in whom medical treatment failed, particularly, in cases of esophageal atresia (EA), congenital diaphragmatic hernia (CDH), and neurologic impairment (NI). Chi-square comparisons and logistic regression were used to test comorbidities, previous abdominal surgery, surgical technique, gastrostomy, pyloromyotomy or pyloroplasty, age, weight, and surgical complications as possible predictors of NF failure. RESULTS: A total of 360 children (217 male and 143 female) underwent NF. Comorbidities were NI (n = 100, 27.8%), EA (n = 50, 13.9%), CDH (n = 22, 6.1%), and abdominal wall defects (AWD) (n = 6, 1.7%). A total of 35 patients (9.7%) had esophageal stenosis. Age at surgery was 3.06 years (0.04-20.7 years) and weight was 12 kg (2-77 kg). NF was open in 196 patients (54.4%) and laparoscopic in 164 patients (45.6%) (with 9 conversions). Follow-up was 6.7 years (0.01-18.7 years). A total of 42 patients (11, 7%) had postoperative complications (10 wound infection, 9 dumping syndrome, 8 gastrostomy related complications, 7 intestinal obstruction, 5 evisceration, 2 chylothorax, and 1 pneumothorax). Reflux recurred in 42 patients (11.7%) and 35 patients (9.7%) underwent redo NF 1.01 years (0.02-8.4 years) after the initial surgery. A total of nine patients (2.5%) required further interventions (five another redo NF, three esophageal replacements, and one esophago-gastric disconnection). A total of 29 patients (8.1%) died during the follow-up (25 because of their baseline disease, 3 in the postoperative period, and 1 because of pulmonary aspiration 3 years after surgery). EA (31.6% failure) and CDH (46.7% failure) were the only comorbidities predictive of NF failure (p < 0.05). CONCLUSIONS: Failure of NF is particularly frequent in patients previously operated upon for EA or CDH and can be predicted preoperatively. However, the benefits of the operation may outweigh this risk. Redo NF is indicated if symptoms of GER recur, but the proportion of failure is even higher. In subsequent failures, other options like esophageal replacement or esophagogastric dissociation should also be considered.

Cephalic pancreaticoduodenectomy for bleeding duodenal arteriovenous malformation.

Introduction Treatment of recurrent severe gastrointestinal bleeding due to arteriovenous malformations may require complex resections. In some particular locations, extensive surgery is the only way out, as shown in this report. Case Report A 2.5-year-old child suffered repeated episodes of upper gastrointestinal bleeding since the first month of life. After an extensive diagnostic workout, the diagnosis of duodenal arteriovenous malformation was established. Cephalic pancreaticoduodenectomy with pyloric preservation was performed and no further episodes of bleeding occurred in the ensuing 2 years. Conclusion Bleeding malformations located in the pancreaticoduodenal area can be effectively treated in children by pylorus-preserving cephalic pancreaticoduodenectomy.
