Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines: 2016 revision

BACKGROUND: Allergic rhinitis (AR) affects 10% to 40% of the population. It reduces quality of life and school and work performance and is a frequent reason for office visits in general practice. Medical costs are large, but avoidable costs associated with lost work productivity are even larger than those incurred by asthma. New evidence has accumulated since the last revision of the Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines in 2010, prompting its update. OBJECTIVE: We sought to provide a targeted update of the ARIA guidelines. METHODS: The ARIA guideline panel identified new clinical questions and selected questions requiring an update. We performed systematic reviews of health effects and the evidence about patients' values and preferences and resource requirements (up to June 2016). We followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) evidence-to-decision frameworks to develop recommendations. RESULTS: The 2016 revision of the ARIA guidelines provides both updated and new recommendations about the pharmacologic treatment of AR. Specifically, it addresses the relative merits of using oral H1-antihistamines, intranasal H1-antihistamines, intranasal corticosteroids, and leukotriene receptor antagonists either alone or in combination. The ARIA guideline panel provides specific recommendations for the choice of treatment and the rationale for the choice and discusses specific considerations that clinicians and patients might want to review to choose the management most appropriate for an individual patient. CONCLUSIONS: Appropriate treatment of AR might improve patients' quality of life and school and work productivity. ARIA recommendations support patients, their caregivers, and health care providers in choosing the optimal treatment.

Clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer prevention in Saudi Arabia

BACKGROUND: Cervical cancer is the third most common gynecological malignancy in Saudi women with an estimated incidence rate of 1.9 cases per 100 000 women-years. More than 40% of cervical cancer cases are diagnosed at advanced stages due to lack of a routine screening program in Saudi Arabia. Thus, national guidelines for routine screening and treatment of precancerous cervical lesions are needed. METHODS: The Saudi Centre for Evidence-Based Healthcare invited a panel of local experts and partnered them with a team from McMaster University in Canada for methodological support, to develop national clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer. After the panel identified key clinical questions, the McMaster University working group updated existing systematic reviews that had been used for the 2013 WHO Guidelines for screening and treatment of precancerous lesions for cervical cancer prevention. Recommendations were based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Those recommendations took into account the available evidence, patient values and preferences, and resource use in the Saudi context. The panel provided recommendations on two major issues: screening for precancerous lesions (cervical intraepithelial neoplasia 2 & 3) and treatment of those lesions to prevent cervical cancer in women who tested positive after screening. CONCLUSIONS: The Saudi expert panel recommends using the HPV DNA test followed by colposcopy or cytology (Pap test) followed by colposcopy to screen for CIN2+ in women at risk of cervical cancer. The panel recommends cryotherapy or loop excision electrosurgery procedure (LEEP) over cold knife cone biopsy to treat women at risk of cervical cancer that tests positive for CIN2+. Universal screening for precancerous cervical dysplasia in women in Saudi Arabia is recommended using HPV testing and or cytology. Either cryotherapy or LEEP are preferred for treatment. CONCLUSIONS: National studies on cervical cancer screening modalities and treatment of precancerous cervical lesions, including HPV prevalence and its association with cervical cancer, are scarce.

Estudio transversal de la desviación del tabique nasal en las fi suras unilaterales operadas / Fertility survey of patients opened on of cryptorchidism in the pediatric age

Introducción. La desviación del tabique nasal es una de las deformaciones nasales más significativas entre los pacientes fisurados unilaterales y sus variaciones anatómicas dentro de la cavidad nasal no han sido del todo precisadas en relación al eje antero-posterior Objetivo. Determinar si existen diferencias en el grado de desviación del tabique nasal entre las zonas anterior, media y posterior de la cavidad nasal, en pacientes operados de fi sura-labio-máxilo-palatina unilateral. Material y método. Veintinueve pacientes operados de fi sura labiomáxilo-palatina unilateral entre 5 y 17 años, controlados en el Hospital San Borja Arriarán y Facultad de Odontología de la Universidad de Chile fueron incluidos. El coeficiente de desviación del tabique nasal fue medido a distintas profundidades a lo largo del eje antero-posterior mediante tomografía computarizada de haz cónico, y comparado utilizando un programa para estimar modelos de efectos aleatorios. Resultados. El coeficiente de desviación del tabique nasal presentó diferencias entre los tres planos estudiados. El plano con menor desviación fue el anterior, mientras que el plano con la mayor desviación fue el posterior. Estas diferencias resultaron estadísticamente significativas (P<0,05).Conclusiones. Durante la corrección quirúrgica del tabique nasal de los pacientes portadores de fi sura unilateral completa se debe prestar mayor atención a la porción posterior de esta estructura, ya que se encuentra más comprometida por la deformidad (AU)

Introduction. Nasal septum deviation is one the most significant nasal deformities among cleft and lip patients and its anatomical variations along the anterior-posterior axis within the nasal cavity has not been specified.Aim. To defi ne whether there are differences in the degree of nasal septum deviation between the anterior, middle and posterior areas of the nasal cavity in operated unilateral cleft lip and palate patients. Material and method. Twenty-nine unilateral complete cleft lip and palate patients, between 5 and 17 years, attending San Borja Arriarán Hospital and the University of Chile’s School of Dentistry were included. The nasal septum deviation index was measured at different depths across the anteroposterior axis by cone-beam computed tomography. A random effects model was performed for data analysis. Results. The nasal septum deviation index presented differences between the three planes studied. The plane with lesser deviation was the anterior, while the plane with greater deviation was the posterior. These differences resulted statistically significant (P<0.05).Conclusion. In complete unilateral cleft and lip patients mainly the posterior part of the nasal septum should be corrected, because there is a greater deviation in that area (AU)
