Cuerpos extraños en otorrinolaringología: Experiencia en Clínica Santa María / Foreign bodies in otolaryngology: Experience at Clínica Santa María

Resumen Introducción: Los cuerpos extraños (CE) en oído, nariz y vía aéreodigestiva superior son el 30% de las urgencia en otorrinolaringología (ORL). No existen datos epidemiológicos nacionales que describan la casuística de CE. Objetivo: Describir la epidemiología de pacientes con diagnóstico de CE evaluados, entre el 2013-2018 en Clínica Santa María de Santiago, Chile. Describir las características de los CE, ubicación, método de extracción y complicaciones. Material y Método: Estudio descriptivo y retrospectivo, basado en revisión de fichas clínicas de pacientes con diagnóstico de CE, analizando variables epidemiológicas y clínicas. Resultados: Se revisaron 1.847 casos con diagnóstico de CE, confirmando 1.494. La mayoría de sexo masculino (53,3%), con un promedio de edad de 16,5 años (rango de 0-95 años). Los CE más prevalentes fueron ótico (52,9%) y nasal (27,9%). El síntoma asociado más frecuente fue la sensación de CE (18,1%). El diagnóstico fue principalmente por examen físico (84%), requiriéndose exámenes complementarios en 18,2%. La extracción fue ambulatoria en su mayoría (84,6%), requiriendo extracción en pabellón el 12,5%. El 5,5% presentó complicaciones, y la tasa de letalidad fue de 0,07%. Conclusión: Esta casuística, única a nivel nacional, nos permite conocer la epidemiología de los CE. Un bajo porcentaje de pacientes fue de riesgo vital, pero el manejo oportuno permite una baja tasa de complicaciones y letalidad.

Abstract Introduction: Foreign bodies (FB) in the ear, nose and upper airway-digestive tract are 30% of the emergencies in otolaryngology (ORL). There is no national epidemiological data that describes the FB casuistry. Aim: To describe the epidemiology of patients who have a diagnosis of a FB evaluated, between 2013-2018, at Santa María Clinic in Santiago, Chile. To describe the characteristics of FB, location, method of removal, and complications. Material and Method: A descriptive and retrospective study, based on review of clinical records of patients with the diagnosis of FB, analyzing epidemiological and clinical variables. Results: 1847 cases with a diagnosis of FB were reviewed, of which 1494 were confirmed. Most were male (53.3%), with an average age of 16.5 years (range 0-95 years). The most prevalent FB locations were otic (52.9%) and nasal (27.9%). The most frequent associated symptom was sensation of a FB (18.1%). The diagnosis was fundamentally based on physical examination (84%), requiring complementary tools in 18.2%. The extraction was mostly ambulatory (84.6%), requiring extraction in the operation room in 12.5%. 5.5% presented complications, and the fatality rate was 0.07%. Conclusion: This casuistry is unique at the national level, and allows us to know the epidemiology of FB. A low percentage of patients correspond to life-threatening locations, but timely management allows a low rate of complications and fatality.

Biobancos en otorrinolaringología / Biobanks in otolaryngology

Resumen Los biobancos son una innovadora herramienta biotecnológica y un recurso fundamental para el continuo avance en la investigación científica biomédica, y para el advenimiento de la medicina de precisión. Se han desarrollado de forma exponencial durante los últimos 20 años en el mundo, como también a nivel de nuestro país, con la creación de 10 biobancos desde el año 2004. En ellos se almacenan y organizan distintos tipos de muestras biológicas, asociadas a datos epidemiológicos y genéticos de donantes voluntarios. Todos los especímenes almacenados deben ser preservados con estándares de calidad garantizados, a modo de asegurar trazabilidad, integridad y calidad de las muestras. A pesar de que la mantención de un biobanco puede significar altos costos, a fin de cuentas, abaratan costos de los estudios clínicos, dado que es precisamente el biobanco quien se encarga de la obtención de datos y muestras clínicas confiables, permitiendo realizar múltiples estudios a partir de las mismas muestras. A través de este proceso, los biobancos permiten mantener una fuente confiable de recur-sos para la investigación en diversas áreas de la medicina, dentro de ellas la otorrinolaringología. En otorrinolaringología, los biobancos han significado un gran avance, facilitando la investigación en relación con hipoacusia, presbiacusia y tinnitus, así como en el área oncológica. En un futuro, se espera que la comunidad científica haga uso de este recurso, pudiendo expandir su utilidad no solo en el área médica, sino también en otras profesiones de la salud, maximizando así su gigantesco potencial.

Abstract Biobanks are novel biotechnological tools and a fundamental resource for the constant development of biomedical research, as much as for the growing practice of precision medicine. They have proliferated worldwide over the past 20 years and Chile has not been left behind with the creation of 10 bio-banks since 2004. Biobanks store and organize different types of biological samples associated with epidemiological and genetic data from volunteer donors. These samples are stored and preserved under guaranteed quality standards to ensure their traceability, integrity, and quality. Even though the price of maintaining a biobank may seem high, after all, they reduce the costs of research, since biobanks are responsible of the acquisition and storage of data and samples, allowing the performance of multiple studies from the same collection of specimens. In this direction, biobanks grant a constant source of well-founded scientific material for investigation in a wide range of medical fields, such as otolaryngology among them. In otolaryngology, the biobanks have meant a great improvement, facilitating investigations related to deafness, presbycusis, tinnitus and oncology. In the future we hope the scientific community will expand the use this innovative tool over a broader medical field and towards other health-related professions, making the most of its enormous potential.

Survival outcomes and prognostic factors of endometrial stromal sarcoma and undifferentiated uterine sarcoma.

PURPOSE: To review the diagnostic and therapeutic procedures of patients diagnosed with Endometrial Stromal Sarcoma (ESS) and Undifferentiated Uterine Sarcoma (USS) at our institution and investigate their clinical outcomes and factors affecting prognosis. METHODS: We retrospectively collected demographic data, preoperative diagnostic methods and therapeutic management of patients treated for ESS and UUS between January 1995 and December 2019 at Vall d'Hebron Barcelona Hospital Campus, Spain. Overall survival and disease-free survival were calculated. Cox proportional-hazards regression models were calculated. RESULTS: Sixty-three patients were included in the study, of which 51(81%) had a diagnosis of ESS and 12(19%) of UUS. Twenty patients (31.7%) were diagnosed after a previous non-oncologic surgery, and 12 of them (60%) suffered from tumor disruption. Cytoreductive procedures were needed in 29 patients (46%), and optimal cytoreduction was achieved in 80.9% of the patients. The median follow-up was 7.6 years (IQR = 0.99-14.31). Five-year overall survival was 57.6% (44.2-68.8) and was significantly better for low-grade ESS (LG-ESS) patients (p < 0.01). Five-year disease-free survival was 57.1% (42.8-69.1) and was also significantly higher in LG-ESS cohort (p = 0.03). After multivariate analysis histological type, age, FIGO stage, optimal surgery and mitotic index were found significantly correlated with survival. For high-grade EES (HG-ESS) and USS patients adjuvant radiotherapy also correlated with improved survival. CONCLUSION: Overall survival and disease-free survival are significantly better in patients with LG-ESS cohort. HG-ESS and UUS show similar survival outcomes. Age, FIGO stage, optimal surgery and histological type were significantly correlated with survival in the global cohort, whilst adjuvant radiotherapy correlated with improved survival in HG-ESS and UUS patients.

Clinical evaluation of the synbiotic Prodefen Plus® in the prevention of the antibiotic-associated diarrhoea in subjects requiring antibiotic treatment.

Prodefen® is a dietary food supplement formulated as a synbiotic that has shown additional benefit to the standard supportive therapy in the management of acute viral diarrhoea in children. There is scarce evidence of this synbiotic in adults. The objective of this randomised double blind placebo-controlled clinical trial was to evaluate the efficacy and safety of Prodefen Plus® in the prevention of antibiotic-associated diarrhoea (AAD) in an adult population requiring either antibiotic treatment for an oral infection or antibiotic prophylaxis for a dental surgical procedure in a dental consultation. 151 subjects were randomised to the active (synbiotic) or control arm (placebo) for 14 days. There was a significantly higher reduction in the AAD incidence, and an improvement in the stool consistency in the active group. A higher reduction in both the frequency and duration of the diarrhoea episodes in the active group was also observed, as it was an improved perception of the diarrhoea severity. Overall, the study medication was well tolerated. In conclusion, results from this study confirm the beneficial effect of the synbiotic administered as adjuvant therapy in preventing the antibiotic-associated diarrhoea.

Disfagia en tiempos de COVID-19 / Dysphagia in COVID-19 times

Resumen Los pacientes con COVID-19 pueden presentar dificultades en la alimentación por distintos factores, entre los que destacan el aumento del esfuerzo respiratorio, uso de dispositivos de apoyo ventilatorio, compromiso neurológico y disfagia postextubación. La evaluación clínica es fundamental, pero debe ser realizada con precaución y con elementos de protección personal, ya que es un procedimiento generador de aerosoles, al igual que la evaluación instrumental mediante videofluoroscopía y evaluación fibroendoscópica de la deglución. Las recomendaciones de manejo deben basarse en la evaluación clínica adaptada, tanto para pacientes ambulatorios como hospitalizados, y debe incluir el manejo nutricional, compensatorio y el seguimiento clínico periódico para evitar las consecuencias de la disfagia orofaríngea, y así disminuir la tasa de neumonía aspirativa, causa importante de morbimortalidad.

Abstract Patients with COVID-19 may present feeding difficulties due to different factors, like the increase in respiratory effort, use of ventilatory support devices, neurological compromise and post-extubation dysphagia. Clinical evaluation is essential, but it must be carried out with caution and using personal protection elements, since it is an aerosol-generating procedure, as well as the instrumental evaluation by videofluoroscopy and fiberoptic endoscopic evaluation of swallowing. Treatment should be based on adapted clinical evaluation, for both outpatients and hospitalized patients, and should include nutritional treatment, compensatory management and periodic clinical follow-up to avoid the consequences of oropharyngeal dysphagia and decrease the rate of aspiration pneumonia major cause of morbidity and mortality.

Ultra-early continuous cardiac monitoring improves atrial fibrillation detection and prognosis of patients with cryptogenic stroke.

BACKGROUND AND PURPOSE: Subclinical atrial fibrillation (AF) is known to underlie a number of cases of cryptogenic stroke (CrS). However, there is need to define the most effective strategy for AF detection. The diagnostic usefulness was analysed of a strategy based on ultra-early continuous monitoring in patients with CrS in terms of AF detection, oral anticoagulation treatment and stroke recurrence, in comparison to a standard outpatient strategy. METHODS: Patients with ischaemic stroke of undetermined origin and confirmed to be cryptogenic after extensive work-up were searched for AF with (i) a conventional strategy (historical cohort, n = 101) with serial electrocardiograms and 24-h Holter monitoring or (ii) an ultra-early monitoring strategy with insertable cardiac monitor (ICM) implanted before discharge (prospective cohort, n = 90). AF episodes lasting >1 min, anticoagulant treatment and stroke recurrence were recorded. RESULTS: During admission, AF was similarly detected in both cohorts (24% of patients). After discharge (mean follow-up 30 ± 10 months), AF detection rates were 17/80 (21.3%) and 38/65 (58.5%) for patients in the conventional versus the ultra-early ICM group (P < 0.001). Up to 41% of AF cases in the ICM cohort were detected within the first month. Oral anticoagulation was initiated in 37.6% versus 65.5% (P < 0.001) and stroke recurrence was recorded in 10.9% versus 3.3% (P 0.04) in the conventional versus the ICM cohort. CONCLUSIONS: Pre-discharge ICM implant allows detection of AF during follow-up in up to 58% of selected patients with CrS. Compared to a conventional strategy, ultra-early ICM implant results in higher anticoagulation rates and a decrease in stroke recurrence.

Oncologic impact of micrometastases or isolated tumor cells in sentinel lymph nodes of patients with endometrial cancer: a meta-analysis.

PURPOSE: There is a gap in knowledge regarding the impact of micrometastases (MIC) and isolated tumor cells (ITCs) found in the sentinel lymph nodes of patients with endometrial cancer. Here, we present a meta-analysis of the published literature on the rate of MIC and ITCs after lymphatic mapping and determine trends in postoperative management. METHODS: Literature search of Medline and PubMed was done using the terms: micrometastases, isolated tumor cells, endometrial cancer, and sentinel lymph node. Inclusion criteria were: English-language manuscripts, retrospectives, or prospective studies published between January 1999 and June 2019. We removed manuscripts on sentinel node mapping that did not specify information on micrometastases or isolated tumor cells, non-English-language articles, no data about oncologic outcomes, and articles limited to ten cases or less. RESULTS: A total of 45 manuscripts were reviewed, and 8 studies met inclusion criteria. We found that the total number of patients with MIC/ITCs was 286 (187 and 99, respectively). The 72% of patients detected with MIC/ITCs in sentinel nodes received adjuvant therapies. The MIC/ITCs group has a higher relative risk of recurrence of 1.34 (1.07, 1.67) than the negative group, even if the adjuvant therapy was given. CONCLUSION: We noted that there is an increased relative risk of recurrence in patients with low-volume metastases, even after receiving adjuvant therapy. Whether adjuvant therapy is indicated remains a topic of debate because there are other uterine factors implicated in the prognosis. Multi-institutional tumor registries may help shed light on this important question.

Evaluation of the intraoperative human papillomavirus test as a marker of early cure at 12 months after electrosurgical excision procedure in women with cervical high-grade squamous intraepithelial lesion: a prospective cohort study.

OBJECTIVE: To evaluate if the intraoperative human papillomavirus (IOP-HPV) test has the same prognostic value as the HPV test performed at 6 months after treatment of high-grade squamous intraepithelial lesion (HSIL) to predict treatment failure. DESIGN: Prospective cohort study. SETTING: Barcelona, Spain. POPULATION: A cohort of 216 women diagnosed with HSIL and treated with loop electrosurgical excision procedure (LEEP). METHODS: After LEEP, an HPV test was performed using the Hybrid Capture 2 system. If this was positive, genotyping was performed with the CLART HPV2 technique. The IOP-HPV test was compared with HPV test at 6 months and with surgical margins. MAIN OUTCOME MEASURE: Treatment failure. RESULTS: Recurrence rate of HSIL was 6%. There was a strong association between a positive IOP-HPV test, a positive 6-month HPV test, positive HPV 16 genotype, positive surgical margins and HSIL recurrence. Sensitivity, specificity, and positive and negative predictive values of the IOP-HPV test were 85.7, 80.8,24.0 and 98.8% and of the HPV test at 6 months were 76.9, 75.8, 17.2 and 98.0%. CONCLUSION: Intraoperative HPV test accurately predicts treatment failure in women with cervical intraepithelial neoplasia grade 2/3. This new approach may allow early identification of patients with recurrent disease, which will not delay the treatment. Genotyping could be useful in detecting high-risk patients. TWEETABLE ABSTRACT: IOP-HPV test accurately predicts treatment failure in women with CIN 2/3.

Evacuación aeromédica de pacientes COVID-19. Reporte de casos / Case reports: Aeromedical evacuation of patients COVID-19

BACKGROUND: The aeromedical evacuation in the Chilean Air Force has had an important development in the last 15 years. The coronavirus disease declared as a global pandemic by the WHO has generated the challenge of transferring highly infectious patients to centers of greater complexity. The objective of this article is to report our experience in the transfer of COVID ­ 19 patients in constant attention and medical monitoring. CLINICAL CASE REPORTS: The aeromedical evacuation of 2 COVID-19 patients was performed from the Hanga Roa Hospital, Rapa Nui, to the National Thorax Institute, Metropolitan Region, in a Lockheed Hercules C-130, which corresponds to a pressurized fixed-wing airplane. The transfer was carried out with the corresponding personal protection elements and in individual isolation capsules with advanced negative pressure life support (ISO ­ POD), in order to reduce the level of contagion to the aero sanitary crew and minimize the impact on the flight material used. DISCUSSION: The transfer was carried out achieving all the objectives set out under a strict security protocol and the two COVID-19 patients were transferred successfully. The negative pressure isolation capsule system was safe and reliable, since no crew member presented symptoms or was infected by COVID -19, and also allowed the transfer of highly contagious patients during an 8-hour flight operation.

INTRODUCCIÓN: La evacuación aeromédica en la Fuerza Aérea de Chile ha tenido un importante desarrollo en los últimos 15 años. La enfermedad por coronavirus declarada como pandemia mundial por la OMS ha generado el desafío de trasladar pacientes altamente infecciosos a centros de mayor complejidad. El objetivo de este artículo es reportar nuestra experiencia en el traslado de pacientes COVID ­ 19 en constante atención y monitorización médica. REPORTE DE CASOS CLÍNICOS: Se realizó la evacuación aeromédica de 2 pacientes COVID ­ 19 desde el Hospital de Hanga Roa, Rapa Nui, hacía el Instituto Nacional del Tórax, Región Metropolitana, en un Lockheed Hércules C-130, que corresponde a un avión de ala fija presurizado. El traslado se realizó con los elementos de protección personal correspondientes y en capsulas de aislamiento individual con soporte vital avanzado a presión negativa (ISO ­ POD), con la finalidad de reducir el nivel de contagio a la tripulación aero sanitaria y minimizar el impacto en el material de vuelo utilizado. DISCUSIÓN: El traslado se desarrolló logrando todos los objetivos planteados bajo un estricto protocolo de seguridad y los dos enfermos COVID-19 fueron trasladados de manera exitosa. El sistema de cápsulas de aislamiento a presión negativa fue seguro y confiable, ya que ningún miembro de la tripulación presento sintomatología o resultó contagiado por COVID -19, y además permitió trasladar pacientes altamente contagiosos durante una operación de vuelo de 8 horas.

ABSTRACT Introduction: Transtympanic gentamicin is used for treatment of patients with chronic vertigo refractory to medical management. Aim: To describe and analyze the clinical outcome of patients whom underwent treatment with transtympanic gentamicin at the Clinical Hospital Universidad de Chile. Material and method: Retrospective and descriptive study including patients with otolaryngologist disease whom underwent treatment with transtympanic gentamicin between 2008 and 2018. Epidemiological, clinical variables and vestibular function were analyzed. Results: The serie consists of ten patients, 7 men and 3 women, with an average age of 52,4 years. The most frequent diagnosis was Ménière disease (7 patients). The average number of gentamicin injections was 2,8. The follow up varies from 1 to 96 months, presenting improvement of vertigo in the majority of the cases (8 of 10 patients). Conclusion: The treatment with transtympanic injections of gentamicin is a relevant option to decrease symptoms in patients with chronic intractable vertigo. It should be indicated in selected patients. Prior and posterior the treatment, patients must be studied with a complete evaluation of the auditory and vestibular function.

Brentuximab vedotin and ESHAP is highly effective as second-line therapy for Hodgkin lymphoma patients (long-term results of a trial by the Spanish GELTAMO Group).

BACKGROUND: In this work, we assessed the efficacy and safety of brentuximab vedotin (BV) plus ESHAP (BRESHAP) as second-line therapy for Relapsed/Refractory Hodgkin lymphoma (RRHL) to improve the results before autologous stem-cell transplantation (ASCT). PATIENTS AND METHODS: This was a multicenter, open-label, phase I-II trial of patients with RRHL after first-line chemotherapy. Treatment had three 21-day cycles of etoposide, solumedrol, high-dose AraC, and cisplatin. BV was administered at three dose levels (0.9, 1.2, and 1.8 mg/kg) intravenous on day ‒1 to 3 + 3 cohorts of patients. Final BV dose was 1.8 mg/kg. Responding patients proceeded to ASCT, followed by three BV courses (1.8 mg/kg, every 21 days). Main end points for evaluation were maximum tolerable dose and overall and complete response (CR) before ASCT. RESULTS: A total of 66 patients were recruited (median age 36 years; range 18-66): 40 were primary refractory, 16 early relapse and 10 late relapse. There were 39 severe adverse events were reported in 22 patients, most frequently fever (n = 25, 35% neutropenic), including 3 deaths. Grade 3-4 hematological toxicity presented in 28 cases: neutropenia (n = 21), thrombocytopenia (n = 14), and anemia (n = 7). Grade ≥3-4 extrahematological adverse events (≥5%) were non-neutropenic fever (n = 13) and hypomagnesaemia (n = 3). Sixty-four patients underwent stem-cell mobilization; all collected >2×10e6/kg CD34+ cells (median 5.75; range 2.12-33.4). Overall response before transplant was 91% (CI 84% to 98%), including 70% (CRs 95% CI 59% to 81%). 60 patients were transplanted with no failure engraftments. Post-transplant response was CR in 49 patients (82% CI 73% to 91%) and partial responses in six (10% CI 5% to 15%). After a mean follow-up of 27 months, the 30-month time to treatment to failure was 74% (95% CI 68% to 80%), progression-free survival 71% (95% CI 65% to 77%), and overall survival 91% (CI 84% to 98%). CONCLUSION: BRESHAP looks a safe and effective pre-transplant induction regimen, does not jeopardize transplant and allows long-term remissions and survival.

Is there benefit to continue magnesium sulphate postpartum in women receiving magnesium sulphate before delivery? A randomised controlled study.

OBJECTIVE: To determine if the use of magnesium sulphate postdelivery reduces the risk of eclampsia in women with severe pre-eclampsia exposed to at least 8 hours of magnesium sulphate before delivery. DESIGN: Randomised multicentre controlled trial. SETTING: Latin America. POPULATION: Women with severe pre-eclampsia that had received a 4-g loading dose followed by 1 g per hour for 8 hours as maintenance dose before delivery. METHODS: In all, 1113 women were randomised; 555 women were randomised to continue the infusion of magnesium sulphate for 24 hours postpartum and 558 were randomised to stopping the magnesium sulphate infusion immediately after delivery. OUTCOME MEASURES: Primary outcome was the incidence of eclampsia in the first 24 hours postdelivery. Secondary outcomes included maternal death, maternal complications, time to start ambulation and time to start lactation. RESULTS: The maternal characteristics at randomisation between the groups were not different. There were no differences in the rate of eclampsia; 1/555 (0.18%) versus 2/558 (0.35%) [relative risk (RR 0.7, 95% CI 0.1-3.3; P = 0.50] or maternal complications between the groups (RR 1.0, 95% CI 0.8-1.2; P = 0.76). Time to start ambulation was significantly shorter in the no magnesium sulphate group (18.1 ± 10.6 versus 11.8 ± 10.8 hours; P = 0.0001) and time to start lactation was equally shorter in the no magnesium sulphate group (24.1 ± 17.1 versus 17.1 ± 16.8 hours; P = 0.0001). CONCLUSIONS: Women with severe pre-eclampsia treated with a minimum of 8 hours of magnesium sulphate before delivery do not benefit from continuing the magnesium sulphate for 24 hours postpartum. TWEETABLE ABSTRACT: No benefit of continuing magnesium sulphate postpartum in severe pre-eclampsia exposed to this drug for a minimum of 8 hours before delivery.

Pathology findings and clinical outcomes after risk reduction salpingo-oophorectomy in BRCA mutation carriers: a multicenter Spanish study.

OBJECTIVE: To determine the incidence of serous tubal intraepithelial carcinoma (STIC) after risk reduction salpingo-oophorectomy(RRSO), and to describe oncological outcomes after RRSO. MATERIALS AND METHODS: BRCA pathogenic mutation carriers who had undergone an RRSO were evaluated in this retrospective multicenter observational study. Patients were only included when fallopian tubes were analyzed following the protocol for Sectioning and Extensively Examining the FIMbria (SEE-FIM). Surgeries were performed between June 2010 and April 2017 at eight Spanish hospitals. RESULTS: A total of 359 patients met the inclusion criteria. STIC was diagnosed in 3 (0.8%) patients; one of them underwent surgical staging due to positive peritoneal washing, with absence of disease at the final pathology report. None of the three patients received adjuvant chemotherapy and were free of disease at last follow-up. Fallopian tube and ovarian carcinoma were diagnosed in 5 (1.4%) and 1 (0.3%), respectively. At a median (range) follow-up time of 29 (3-92) months, five patients had a newly diagnosed breast cancer. Other types of cancer, which were diagnosed during the follow-up time, included: serous primary peritoneal carcinoma (n = 1), serous endometrial carcinoma (n = 1), colon (n = 1), pancreas (n = 1), jaw (n = 1), and lymphoma (n = 1). Seven patients died due to different types of cancer: breast (n = 4), pancreas (n = 1), jaw (n = 1), and colon (n = 1). CONCLUSION: The incidence of STIC after RRSO in BRCA mutation carriers is low (0.8%) and it presents an excellent oncological outcome. Patients after RRSO, however, run the risk to develop other types of cancer during follow-up and should be properly advised before the prophylactic surgery.

Manejo endoscópico del meningoencefalocele de base de cráneo anterior / Endoscopic management of anterior skull base meningoencephalocele

RESUMEN La fístula de líquido cefalorraquídeo (LCR) corresponde a una comunicación anormal entre el espacio subaracnoideo y la porción neumatizada de la base de cráneo anterior en relación con las cavidades paranasales. Fístulas persistentes requieren reparación quirúrgica por el riesgo de meningitis, abscesos cerebrales y neumoencéfalo asociado. El gold standard es el abordaje extracraneal endoscópico. Uno de los principales inconvenientes es dañar estructuras intracraneanas nobles. La ayuda de tecnologías como la cirugía guiada por imágenes, contribuye a disminuir este problema. A continuación se presentan dos casos clínicos de fístula de líquido cefalorraquídeo en base de cráneo anterior, asociado a meningoencefalocele, intervenidos por cirugía endonasal guiada por imágenes.

ABSTRACT Endoscopic management of anterior skull base meningoencephalocele. The cerebrospinal fluid leak (CSF) is an abnormal communication between the subaracnoid space and the pneumatic portion of the anterior cranial base which is related to the paranasal cavities. The persistent leak requires surgery due to the potential complications such as meningitis, cerebral abscess or pneumoencephalus. Extracranial endoscopic approach is the gold standard procedure. One of the most important risk of the surgery is to damage noble intracranial structures. This situation can be ameliorated by using image guided surgery. We present two cases of CSF in anterior cranial base associated with meningoencephalocele that were treated in our center using nasal image guided endoscopic surgery.

Factors associated with implementation of the 5A's smoking cessation model.

BACKGROUND: Several health organizations have adopted the 5A's brief intervention model (Ask, Advise, Assess, Assist, Arrange), based on evidence-based guidelines for smoking cessation. We examine individual, cognitive, behavioral, and organizational factors associated with the 5A's performance among clinical healthcare workers in Catalonia. We also investigate how these factors interact and potentially predict the implementation of each component of the 5A's. METHODS: A cross-sectional survey was conducted among clinical health workers enrolled in an online smoking cessation training course (n = 580). The survey included questions about individual characteristics as well as cognitive, behavioral, and organizational factors previously identified in research. We assessed self-reported performance of the 5A's, assessed on a scale from 0 to 10, and used Multivariate regression to examine factors associated with its performance. RESULTS: The performance means (standard deviation) were moderate for the first 3A's [Ask: 6.4 (3.1); Advise: 7.1 (2.7); Assess: 6.3 (2.8)] and low for the last 2A's [Assist: 4.4 (2.9); Arrange: 3.2 (3.3)]. We observed a high correlation between Assist and Arrange (r = 0.704, p < 0.001). Having positive experiences and feeling competent were positively associated with performing the 5A's model and having organizational support with Assist and Arrange. Personal tobacco use among healthcare workers was negatively associated with Advice and Arrange. CONCLUSIONS: Our study found that clinical healthcare workers do not perform the 5A's completely. The main barriers identified suggest the need of training and making available practical guidelines in healthcare services. Organizational support is essential for moving towards the implementation of Assist and Arrange.

Experiencia con el balón de Bakri en hemorragia obstétrica / Brakri balloon experience in obstetric hemorrhage

Resumen OBJETIVO: reportar la experiencia con el balón de Bakri en el control de la hemorragia obstétrica, su relación con la cantidad y concentraciones de hemoglobina antes y después de su aplicación. MATERIALES Y MÉTODOS: estudio prospectivo y observacional efec- tuado en dos unidades hospitalarias del 1 de enero al 31 de diciembre de 2016. A todas las pacientes se les aplicó el balón de Bakri por falta de respuesta a los uterotónicos. Variables de estudio: datos clínicos, cantidad de pérdida sanguínea antes y después de la aplicación del balón, cantidad de sangrado en el posparto y transcesárea, tiempo trascurrido entre el diagnóstico y la colocación, tiempo de llenado y volumen administrado, concentraciones de hemoglobina y pruebas de coagulación al ingreso a la unidad de atención, postsangrado y posterior a la aplicación, indicación de hemocomponentes, cantidad y tiempo de permanencia del balón, éxito y complicaciones. Se realizó análisis estadístico de todas estas variables. RESULTADOS: se incluyeron 20 pacientes con hemorragia posparto y transcesárea. La cantidad de sangrado después de la aplicación, tanto en los casos de posparto como transcesárea, fue menor y se obtuvo una adecuada respuesta. El tiempo medio entre el diagnóstico de la hemorragia y la colocación del balón fue de 30 minutos, tiempo medio de llenado de 5 minutos y cantidad media de llenado de 400 mL. El tiempo medio de permanencia del balón fue de 29.5 horas. En 95% de los casos se consiguió una respuesta favorable para el control de la hemorragia, sin complicaciones. CONCLUSIONES: la aplicación del balón de Bakri resultó en una medida útil, rápida y sin complicaciones para controlar la hemorragia obstétrica.

Abstract OBJECTIVE: To present the results obtained by using the Bakri Balloon to control obstetric hemorrhage. MATERIALS AND METHOD: Prospective, observational study within two inpatient medical care units from January 1 to December 31 2016. All of them were applied the Bakri Balloon because of failure to respond to uterotonic drug therapy. The following were analized: clinical data, amount of bleeding before and after the balloon, amount of postpartum or transcesarean bleeding, time between diagnosis and insertion, insufflation time and supplied volumen, hemoglobin levels and coagulation tests results initially, post-hemorrhage and post insertion, use of and amount of haemocomponents ministered, and the balloons use time, success, and complications. RESULTS: 20 patients with postpartum and transesarean hemorrhage are included. The amount of bleeding after insertion, both in postpartum and trans cesarean was reduced and there was an adequate response in hemoglobin levels. The average time between hemorrhage diagnosis and balloon insertion was thirty minutes; average insufflation time, five minutes, and average volumen supplied 400 mL. Balloon's average use time, 29.5 hours. In 95% of the cases there was a positive response for hemorrhage control, with no complications derived from use. CONCLUSIONS: The Bakri Balloon proved to be a useful, quick and complication-free therapy for controlling obstetric hemorrhage.
