Quistes sinusales en la cirugía de elevación de seno maxilar. Revisión de la literatura / Sinus cysts in maxillary sinus lift surgery. Review of the literature

Introducción: Tras la pérdida de dientes, acontece la reabsorción del hueso alveolar y la neumatización del seno maxilar, lo cual en ocasiones puede dificultar la colocación de implantes. Una de las técnicas para afrontar este problema es la cirugía de elevación del seno, si bien previamente se debe realizar una evaluación exhaustiva ya que el seno podría presentar patologías que puedan provocar complicaciones. Una de las patologías más comunes son los quistes sinusales Objetivo: Valorar la posibilidad de realizar la cirugía de elevación del seno maxilar en presencia de quistes sinusales. Metodología: Se realizó una búsqueda a través de bases de datos científicas, tras someter la bibliografía a criterios de inclusión y exclusión, se referencian 26 artículos. Resultados y discusión: Anteriormente se creía que la presencia de estas lesiones era una contraindicación. Sin embargo, actualmente los autores afirman que se puede realizar elevaciones de seno maxilar aun cuando estos presenten un quiste sinusal. En la actualidad existen tres enfoques principales para tratar los quistes del seno maxilar en pacientes que se someten a una elevación de seno, extirpación antes de la cirugía, durante la cirugía, o sin extirparlos. El factor más importante es elegir el plan quirúrgico correcto. Conclusión: Actualmente la presencia de quistes sinusales es considerada un factor de riesgo para la cirugía de elevación de seno, pero no es una contraindicación. Los tres enfoques de actuación han demostrado dar resultados positivos (AU)

Utilidad clínica de la determinación de niveles de CT-P13, biosimilar de infliximab, en el control de la enfermedad inflamatoria intestinal / Clinical value of CT-P13 trough levels, an infliximab biosimilar, in the management of inflammatory bowel disease

INTRODUCCIÓN: CT-P13 es un fármaco biosimilar de infliximab (IFX), efectivo en pacientes con enfermedad inflamatoria intestinal (EII). La medición de niveles de IFX y anticuerpos anti-IFX forma parte del tratamiento integral de dicha enfermedad. OBJETIVO: Comparar la respuesta clínica en función de un abordaje estrictamente clínico (CLN) o proactivo (PRO) basado en la medición de niveles en la semana 14, en la práctica clínica. MÉTODOS: Estudio prospectivo en pacientes que inician CT-P13 por EII. En el grupo PRO se midieron sistemáticamente los niveles de IFX y de anticuerpos postinducción (semana 14) y se intensificaron aquellos con niveles infraterapéuticos (<3μg/ml), independientemente de la respuesta clínica. RESULTADOS: Se incluyeron 77 pacientes (23 colitis ulcerosa y 54 enfermedad de Crohn). Ambos grupos, PRO (n=41) y CLN (n=36) presentaron una eficacia inicial y a largo plazo sin diferencias significativas. En la semana 14 hubo un 61% de remisión clínica (RC) (58,5% PRO, 63,9% CLN) y un 80,5% de al menos respuesta parcial (RP) (80,5% PRO, 80,6% CLN). En la semana 54 hubo un 68,8% de RC (61% PRO, 77,8% CLN) y un 76,6% de al menos RP (73,2% PRO, 80,6% CLN). De los pacientes en RC en la semana 14 (24 PRO, 23 CLN), 13 del grupo PRO fueron intensificados por niveles infraterapéuticos. En este subgrupo no se observaron diferencias significativas en la pérdida de respuesta secundaria (PRO 0%, CLN 8,7%). CONCLUSIÓN: Un manejo proactivo no mejoró las tasas de respuesta ni la remisión en el primer año. La intensificación de pacientes en RC y niveles infraterapéuticos postinducción no parece prevenir de forma significativa la pérdida de respuesta secundaria en el primer año

INTRODUCTION: CT-P13 is a biosimilar drug of infliximab (IFX), effective in patients with inflammatory bowel disease (IBD). The monitoring of levels of IFX and anti-IFX antibodies is now considered part of the integral management. OBJECTIVE: To compare the clinical response according to a strictly clinical (CLN) or proactive (PRO) approach based on the monitoring of levels in week 14, in clinical practice. METHODS: We conducted a prospective study in IBD patients starting CT-P13. In the PRO group, levels of IFX and post-induction antibodies were systematically measured (week 14) and those with infraterapeutic levels (<3μg/ml) were intensified, irrespective of the clinical response. RESULTS: We included 77 patients (23 ulcerative colitis and 54 Crohn's disease). Both PRO (n=41) and CLN (n=36) groups showed initial and long-term efficacy without significant differences. At week 14, 61% clinical remission (CR) (58.5% PRO, 63.9% CLN) and 80.5% at least partial response (PR) (80.5% PRO, 80.6% CLN). In week 54, 68.8% CR (61% PRO, 77.8% CLN) and 76.6% at least PR (73.2% PRO, 80.6% CLN). Of the patients in CR in week 14 (24 PRO, 23 CLN), 13 of the PRO group were intensified due to infra-therapeutic levels. In this subgroup no significant differences were observed in secondary loss of response (PRO 0%, CLN 8.7%). CONCLUSION: Proactive management does not improve response or remission rates in the first year. The intensification of clinical remission patients with post-induction infratherapeutic levels does not seem to significantly prevent secondary loss of response in the first year

The discovery BPD (D-BPD) program: study protocol of a prospective translational multicenter collaborative study to investigate determinants of chronic lung disease in very low birth weight infants.

BACKGROUND: Premature birth is a growing and serious public health problem affecting more than one of every ten infants worldwide. Bronchopulmonary dysplasia (BPD) is the most common neonatal morbidity associated with prematurity and infants with BPD suffer from increased incidence of respiratory infections, asthma, other forms of chronic lung illness, and death (Day and Ryan, Pediatr Res 81: 210-213, 2017; Isayama et la., JAMA Pediatr 171:271-279, 2017). BPD is now understood as a longitudinal disease process influenced by the intrauterine environment during gestation and modulated by gene-environment interactions throughout the neonatal and early childhood periods. Despite of this concept, there remains a paucity of multidisciplinary team-based approaches dedicated to the comprehensive study of this complex disease. METHODS: The Discovery BPD (D-BPD) Program involves a cohort of infants < 1,250 g at birth prospectively followed until 6 years of age. The program integrates analysis of detailed clinical data by machine learning, genetic susceptibility and molecular translation studies. DISCUSSION: The current gap in understanding BPD as a complex multi-trait spectrum of different disease endotypes will be addressed by a bedside-to-bench and bench-to-bedside approach in the D-BPD program. The D-BPD will provide enhanced understanding of mechanisms, evolution and consequences of lung diseases in preterm infants. The D-BPD program represents a unique opportunity to combine the expertise of biologists, neonatologists, pulmonologists, geneticists and biostatisticians to examine the disease process from multiple perspectives with a singular goal of improving outcomes of premature infants. TRIAL REGISTRATION: Does not apply for this study.

Actualización en el manejo de la degeneración macular asociada a la edad / Management of age-related macular degeneration. An update

La degeneración macular asociada a la edad (DMAE) es la primera causa de ceguera legal en mayores de 50 años en los países desarrollados. Se trata de una enfermedad multifactorial que resulta de la interacción de factores genéticos y ambientales, en la que el único factor de riesgo universalmente admitido es la edad. El impacto socioeconómico de la enfermedad alcanza proporciones colosales si consideramos los elevados costes del tratamiento antiangiogénico disponible, el estricto régimen de revisiones que precisa y la dependencia que origina. La respuesta al tratamiento y los resultados visuales mejoran con el abordaje temprano de las lesiones, por lo que resulta fundamental el diagnóstico de la enfermedad en fases iniciales, basado en el autocontrol con la rejilla de Amsler y en revisiones oftalmológicas periódicas(AU)

Age-related macular degeneration is the leading cause of legal blindness in people over 50 in developed countries. It is a multifactorial disease resulting from the interaction of genetic and environmental factors, and the age is the only worldwide admitted risk factor. The socioeconomic impact of the disease reaches enormous proportions, if we take into account the high cost of the available antiangiogenic therapy, the strict schedule of medical visits that it requires, and the impairment that it gives rise to. The response to treatment and the visual outcomes improve with early management of the retinal lesions, thus the early diagnosis of the disease in its initial phases, based on self-control with an Amsler grid and with regular ophthalmologic assessments, is essential(AU)
