National Clinical Practice Guidelines for the management of non-small cell lung cancer in early, locally advanced and metastatic stages. Extended version. / Guía de Práctica Clínica Nacional para el manejo del cáncer de pulmón de células no pequeñas en estadios tempranos, localmente avanzados y metastásicos.

OBJECTIVE: Lung cancer is one the leading causes of mortality worldwide. Symptomatic manifestations of the disease generally occur in the advanced-stage setting, and therefore an important number of patients have advanced or metastatic disease by the time they are diagnosed. This situation contributes to a poor prognosis in the treatment of lung cancer. Evidencebased clinical recommendations are of great value to support decision-making for daily practice, and thus improving health care quality and patient outcomes. MATERIALS AND METHODS: This document was an initiative of the Mexican Society of Oncology (SMEO) in collaboration with Mexican Center of Clinical Excellence (Cenetec) according to Interna- tional Standards. Such standards included those described by the IOM, NICE, SIGN and GI-N. An interdisciplinary Guideline Development Group (GDG) was put together which included medical oncologists, surgical oncologistsc, radiation therapists, and methodologists with expertise in critical appraisal, sys- tematic reviews and clinical practice guidelines development. RESULTS: 62 clinical questions were agreed among members of the GDG. With the evidence identified from systematic reviews, the GDG developed clinical recommendations using a Modified Delphi Panel technique. Patients' representatives validated them. CONCLUSIONS: These Clinical Practice Guideline aims to support the shared decision-making process for patients with different stages of non-small cell lung cancer. Our goal is to improve health-care quality on these patients.

OBJETIVO: El cáncer de pulmón es una de las principales causas de mortalidad alrededor del mundo. Su historia natural, con la manifestación de síntomas en etapas avanzadas y el retraso en su diagnóstico hacen que una gran proporción de pacientes se diagnostiquen en estadios tardíos de la enfermedad, lo que hace muy complicado el tratamiento exitoso de la misma. De esto deriva la importancia de dar origen a recomendaciones basadas en evidencia para soportar la toma de decisiones clínicas por parte de los grupos interdisicplinarios que se encargan del manejo de este padecimiento. MATERIAL Y MÉTODOS: Este documento se desarrolló por parte de la Sociedad Mexicana de Oncología en colaboración con el Centro Nacional de Excelencia Tec- nológica de México (Cenetec) a través de la dirección de integración de Guías de Práctica Clínica en cumplimiento a estándares internacionales como los descritos por el Ins- tituto de Medicina de EUA (IOM, por sus siglas en inglés), el Instituto de Excelencia Clínica de Gran Bretaña (NICE, por sus siglas en inglés), la Red Colegiada para el Desarrollo de Guías de Escocia (SIGN, por sus siglas en inglés), la Red Internacional de Guías (G-I-N, por sus siglas en inglés); entre otros. Se integró en representación de la Sociedad Mexicana de Oncología un Grupo de Desarrollo de la Guía (GDG) de manera interdisciplinaria, considerando oncólogos médicos, cirujanos oncólogos, cirujanos de tórax, radio-oncólogos, y metodólogos con experiencia en revisiones sistemáticas de la literatura y guías de práctica clínica. RESULTADOS: Se consensuaron 62 preguntas cllínicas que abarcaron lo establecido previamente por el GDG en el documento de alcances de la Guía. Se identificó la evidencia científica que responde a cada una de estas preguntas clínicas y se evaluó críticamente la misma, antes de ser incorporada en el cuerpo de evidencia de la Guía. El GDG acordó mediante la técnica de consenso formal de expertos Panel Delphi la redacción final de las recomendaciones clínicas. C. CONCLUSIONES: Esta Guía de Práctica Clínica pretende proveer recomendaciones clínicas para el manejo de los distintos estadios de la enfermedad y que asistan en el proceso de toma de decisiones compartida. El GDG espera que esta guía contribuya a mejorar la calidad de la atención clínica en las pacientes con cáncer de pulmón de células no pequeñas.

Immunity-targeted approaches to the management of chronic and recurrent upper respiratory tract disorders in children.

BACKGROUND: Upper respiratory tract infections (URTIs), including rhinitis, nasopharyngitis, tonsillitis and otitis media (OM), comprise of 88% of total respiratory infections, especially in children. Therefore effective prevention and treatment of RTIs remain a high priority worldwide. Preclinical and clinical data highlight the rationale for the use and effectiveness of immunity-targeted approaches, including targeted immunisations and non-specific immunomodulation in the prevention and management of recurrent upper RTIs. OBJECTIVE OF REVIEW: The idea of this review was to summarise the current evidence and address key questions concerning the use of conservative and immunity-targeted approaches to recurrent and chronic URTIs, with a focus on the paediatric population. SEARCH STRATEGY/EVALUATION METHOD: Literature searches were conducted in March 2017 and updated in September 2017 using: Academic Search Complete; CENTRAL; Health Source: Nursing/Academic Edition; MEDLINE; clinicaltrials.gov; and Cochrane databases. In total, 84 articles were retrieved and reviewed. Two independent researchers focused on primary and secondary endpoints in systematic reviews, meta-analyses and randomised, controlled trials, using immunity-directed strategies as the control group or within a subpopulation of larger studies. Existing guidelines and interventional/observational studies on novel applications were also included. RESULTS: Children are particularly susceptible to RTIs due to the relative immaturity of their immune systems, as well as other potential predisposing factors such as day care attendance and/or toxic environmental factors (eg increased pathogenic microbial exposure and air pollutants). Recurrent URTIs can affect otherwise healthy children, leading to clinical sequelae and complications, including the development of chronic conditions or the need for surgery. Available pre-clinical and clinical data highlight the rationale for the use and effectiveness of immunity-targeted approaches, including targeted immunisations (flu and pneumococcal vaccines) and non-specific immunomodulation (bacterial lysates), in the prevention and management of recurrent croup, tonsillitis, otitis media, recurrent acute rhinosinusitis and chronic rhinosinusitis. CONCLUSIONS: In this review, we summarise the current evidence and provide data demonstrating that some immunity-targeted strategies, including vaccination and immunomodulation, have proved effective in the treatment and prevention of recurrent and chronic URTIs in children.

Report of an unsual case of anophthalmia and craniofacial cleft in a newborn with Toxoplasma gondii congenital infection.

BACKGROUND: We present one unusual case of anophthalmia and craniofacial cleft, probably due to congenital toxoplasmosis only. CASE PRESENTATION: A two-month-old male had a twin in utero who disappeared between the 7th and the 14th week of gestation. At birth, the baby presented anophthalmia and craniofacial cleft, and no sign compatible with genetic or exposition/deficiency problems, like the Wolf-Hirschhorn syndrome or maternal vitamin A deficiency. Congenital toxoplasmosis was confirmed by the presence of IgM abs and IgG neo-antibodies in western blot, as well as by real time PCR in blood. CMV infection was also discarded by PCR and IgM negative results. Structures suggestive of T. gondii pseudocysts were observed in a biopsy taken during the first functional/esthetic surgery. CONCLUSIONS: We conclude that this is a rare case of anophthalmia combined with craniofacial cleft due to congenital toxoplasmosis, that must be considered by physicians. This has not been reported before.
