RESUMO
OBJECTIVES: Metabolic Syndrome (MetS) has been established as a significant factor in the pathogenesis of numerous chronic inflammatory conditions. However, its role in Chronic Rhinosinusitis with Nasal Polyps (CRSwNP) is unknown. This study aims to investigate the association between MetS, its components, and the risk of postoperative recurrence in Chinese patients with CRSwNP. METHODS: A retrospective cohort study was conducted on CRSwNP patients who underwent endoscopic sinus surgery in our hospital. Patients were divided into MetS and non-MetS groups, and the clinical characteristics and recurrence rates were compared. All CRSwNP patients were followed up for more than 2-years and further categorized into non-recurrent and recurrent groups. Binary logistic regression analyses were performed to examine the effects of MetS and its components on the risk of postoperative recurrence. RESULTS: A total of 555 CRSwNP patients were enrolled in the present study, 157 patients were included in the MetS group and 398 patients were categorized into the non-MetS group. The recurrence rate in the MetS group was significantly higher compared to the non-MetS group (pâ¯<â¯0.05). The rate of MetS, overweight or obesity, hyperglycemia and dyslipidemia were higher in the recurrent group in comparison with the non-recurrent group (pâ¯<â¯0.05). Multivariate logistic regression analysis suggested that MetS, overweight or obesity, hyperglycemia, dyslipidemia, and accompanying allergic rhinitis were associated with the risk of postoperative recurrence of CRSwNP (pâ¯<â¯0.05). Moreover, adjusted and unadjusted regression models showed that MetS was an independent risk factor for postoperative recurrence of CRSwNP, and the risk increased with more components of MetS included (pâ¯<â¯0.05). CONCLUSION: Our findings revealed that MetS independently increased the risk of postoperative recurrence in patients with CRSwNP, with the risk escalating as the number of MetS components increased. Moreover, accompanying allergic rhinitis was also demonstrated to be a potential risk factor for CRSwNP recurrence. LEVEL OF EVIDENCE: Level 4.

RESUMO
Objective: To evaluate the clinical response of patients with cystic fibrosis and primary ciliary dyskinesia after endoscopic sinus surgery at the Dr. Robert Reid Cabral Children's Hospital from September 2021 to February 2022. Methods: An ambispective, cross-sectional, observational case series study was conducted, where the study population was made up of patients with cystic fibrosis and primary ciliary dyskinesia at the Dr. Robert Reid Cabral children's hospital during the study period. Inclusion criteria: Patients older than 6 years with a confirmed diagnosis of cystic fibrosis and primary ciliary dyskinesia (Genetic test with 2 homozygous mutations, positives electrolytes in sweat), severe respiratory symptoms of CRS that did not improve with conventional treatment and underwent endoscopic surgery for sinuses. Results: Of a total of 41 patients, only 10 met the inclusion criteria, the most prevalent age range was 14 to 18 years. Both CF and PCD patients decreased the frequency of CRS symptoms. After ENC, there were discrete changes in lung function, and only patients with severe to moderate disease increased % of FEV1. Most of the patients did not require admission after surgery. The most common germ found in nasopharyngeal and sputum cultures in preoperative patients was Pseudomonas aeruginosa in 86%; after ESS there was a significant increase in MRSA colonization in both CF and PCD patients. More than 50% of postoperative patients improved their quality of life, so endoscopic sinus surgery is effective in this population in the treatment of chronic rhinosinusitis.
Objetivo: Evaluar la respuesta clínica de los pacientes con fibrosis quística y discinesia ciliar primaria posterior a la cirugía endoscópica de senos paranasales en el Hospital Infantil Dr. Robert Reid Cabral en el período septiembre 2021 a febrero 2022. Métodos: Se realizó un estudio observacional tipo serie de casos, de corte transversal y ambispectivo, donde la población estudiada estuvo conformada por los pacientes con fibrosis quística y discinesia ciliar primaria del hospital infantil Dr. Robert Reid Cabral en el período de estudio. Criterios de inclusión: Pacientes mayores de 6 años con diagnóstico confirmado de fibrosis quística y discinesia ciliar primaria (Prueba genética con 2 mutaciones homocigotas, electrolitos en sudor positivos), síntomas respiratorios severos de RSC que no mejoraron con tratamiento convencional y sometidos a la cirugía endoscópica de senos paranasales. Resultados: De un total de 41 pacientes, sólo 10 cumplieron con los criterios de inclusión, el rango de edad más prevalente fue de 14 a 18 años. Tanto los pacientes con FQ como los de DCP disminuyeron la frecuencia de los síntomas de RSC. Posterior a la CEN hubo cambios discretos en la función pulmonar, y sólo los pacientes con enfermedad grave a moderada aumentaron el % de FEV1. La mayoría de los pacientes no ameritaron ingresos posterior a la cirugía. El germen más común encontrado en los cultivos nasofaríngeo y esputo en los pacientes preoperatorios fue la Pseudomonas aeruginosa en el 86%, luego de la CEN hubo un aumento significativo de la colonización por MRSA tanto en los pacientes con FQ como en los de DCP. Más del 50% de los pacientes postquirúrgicos mejoraron su calidad de vida, por lo que la cirugía endoscópica de senos paranasales es efectiva en dicha población en el tratamiento de la rinosinusitis crónica.

OBJECTIVES: For the treatment of chronic rhinosinusitis functional endoscopic sinus surgery is a well-established therapy with high initial success rates. However, a significant proportion of patients have persistent disease requiring revision surgery. To date, studies including data of large patient collectives are missing. In this study, we aimed to identify anatomic factors increasing the need for revision surgery in a large patient collective with chronic rhinosinusitis without nasal polyps. METHODS: Data were collected retrospectively on patients with recurrent or persistent chronic rhinosinusitis without nasal polyps requiring revision surgery. The patients' symptomatology, endoscopic and radiographic findings were analyzed. Preoperatively, patients were evaluated with endoscopic examination of the nose and paranasal sinuses. In all individuals computed tomography of the sinuses was performed. Images were evaluated according to the Lund-Mackay system. Information was also collected intraoperatively. RESULTS: 253 patients were included. The most common anatomic factor was incomplete anterior ethmoidectomy (51%), followed by residual uncinated process (37%), middle turbinate lateralization (25%), incomplete posterior ethmoidectomy (20%), frontal recess scarring (19%), and middle meatal stenosis (9%). Other factors such as persistent sphenoid pathology was less frequent. CONCLUSION: Iatrogenic causes with inadequate resection of obstructing structures seem to be a principal risk factor for recurrent chronic rhinosinusitis and the need for revision sinus surgery. Meticulous attention in the area of the ostiomeatal complex during surgery with ventilation of obstructed anatomy as well as avoidance of scarring and turbinate destabilization may reduce the failure rate after primary endoscopic sinus surgery. LEVEL OF EVIDENCE: 2b.

RESUMO
Abstract Introduction Controlled hypotension is a reversible procedure in which the patient's baseline mean arterial blood pressure is reduced by 30% and sustained at 60-70 mmHg during the procedure. It decreases blood loss and provides clear surgical field during the procedures. Objectives The purpose of this study was to compare the efficacy of controlled hypotension agents esmolol, remifentanil, and nitroglycerin in functional endoscopic sinus surgery, in terms of hemodynamic changes and impact on the surgical efficiency. Methods The research was carried out as a cohort study. Patients who underwent functional endoscopic sinus surgery were randomized into 3 groups. Controlled hypotension was achieved with remifentanil (Group R), esmolol (Group E) and nitroglycerin (Group N). The efficacy of the drugs was tested by comparing the length of time with the targeted mean arterial pressure, the amount of anesthetics used, surgical field bleeding score and surgeon's satisfaction. Results Between May to December 2015, 60 patients were included and randomized equally into 3 different study groups. The median of the length of time with the targeted mean arterial pressure was shorter in the Group R when compared with Group E (p = 0.01) and Group N (p = 0.14). The amount of volatile anesthetics used was 25.0 mL (15-51), 43.0 mL (21-105) and 40.0 mL (26-97) in Groups R, E and N, respectively (p < 0.001). While there was more bleeding with nitroglycerin, surgical field bleeding scores were lower in Group R when compared with esmolol (p = 0.001) and nitroglycerin (p < 0.001). The analysis of surgeon's satisfaction scores concluded that surgeons were more satisfied with the group R (100%), when compared with group E (60%) and group N (30%) (p < 0.001). Conclusion Less volatile agent, short time to achieve controlled hypotension, stable blood pressure, lower surgical field bleeding scores and larger length of time with the targeted mean arterial pressure were found as the advantages of Remifentanil. Less costly, efficiency of achieving the targeted median arterial pressure and less postoperative complications were the advantages of nitroglycerin. In functional endoscopic sinus surgery procedures, appropriate controlled hypotensive agents should be selected according to the patients' characteristics and advantages/disadvantages of the drugs.
Resumo Introdução Hipotensão controlada é um procedimento reversível no qual a pressão arterial média basal do paciente é reduzida em 30% e mantida em 60-70 mmHg durante o procedimento. Isso diminui a perda de sangue e propicia um campo cirúrgico limpo durante os procedimentos. Objetivo Comparar agentes usados para hipotensão controlada: esmolol, remifentanil e nitroglicerina em cirurgia sinusal endoscópica funcional, em termos de alterações hemodinâmicas e impactos na eficácia cirúrgica. Método O estudo foi feito como de coorte. Pacientes submetidos à cirurgia sinusal endoscópica funcional foram randomizados em 3 grupos. A hipotensão controlada foi feita com remifentanil (Grupo R), esmolol (Grupo E) e nitroglicerina (Grupo R). A eficácia dos medicamentos foi testada com a comparação do período de tempo com a pressão arterial média desejada, a quantidade de anestésicos usados, o escore de sangramento no campo cirúrgico e a satisfação do cirurgião. Resultados Entre maio e dezembro de 2015, 60 pacientes foram incluídos e randomizados igualmente nos três grupos de estudo. A mediana do período com a pressão arterial desejada foi menor no Grupo R quando comparado ao Grupo E (p = 0,01) e Grupo N (p = 0,14). A quantidade de anestésicos voláteis usados foi de 25,0 mL (15 ± 51), 43,0 mL (21 ± 105) e 40,0 mL (26 ± 97) nos Grupos R, E e N, respectivamente (p < 0,001). Houve mais sangramento com nitroglicerina e escores de sangramento no campo cirúrgico foram menores no Grupo R quando comparados com esmolol (p = 0,001) e nitroglicerina (p < 0,001). A análise dos escores da satisfação do cirurgião concluiu que os cirurgiões estavam mais satisfeitos com o grupo R (100%) quando comparados ao grupo E (60%) e o grupo N (30%) (p < 0,001). Conclusão Agente menos volátil, pouco tempo para obter a hipotensão controlada, pressão arterial estável, menor escore de sangramento no campo cirúrgico e período de pressão arterial desejada curto foram considerados como vantagens do remifentanil. Menor custo, eficácia de obtenção da pressão arterial média desejada e menos complicações pós-operatórias foram as vantagens da nitroglicerina. Nos procedimentos de cirurgia sinusal endoscópica funcional, os agentes apropriados para obtenção de hipotensão controlada devem ser selecionados de acordo com as características dos pacientes e as vantagens/desvantagens dos fármacos.

OBJECTIVE: To compare functional endoscopic sinus surgery with a combined approach (functional endoscopic sinus surgery plus Caldwell-Luc procedure) for the treatment of paediatric antrochoanal polyp, in terms of antrochoanal polyp recurrence and safety. METHOD: This retrospective case series comprises 27 paediatric patients with recurrent antrochoanal polyp, treated from January 2010 to January 2018. RESULTS: The average age of the patients at the time of diagnosis was 10.4 ± 2.49 years. The recurrence rate after functional endoscopic sinus surgery alone was 72.9 per cent, compared with 12.5 per cent after functional endoscopic sinus surgery plus the Caldwell-Luc procedure (p < 0.00001). No complications were reported during surgery or follow up. CONCLUSION: The correct identification of the origin of the antrochoanal polyp and an adequate returning of maxillary ventilation by widening the ostium can prevent recurrences. Although functional endoscopic sinus surgery continues to be the 'gold standard' for antrochoanal polyp treatment, in cases of revision surgery, a combined approach could ensure the complete removal of the polyp through the two openings.

BACKGROUND: Staphylococcus aureus and Pseudomonas aeruginosa are common culture isolates in chronic rhinosinusitis (CRS). We aimed to determine whether they were associated with different clinical factors of CRS. METHODS: Adult CRS patients who underwent functional endoscopic sinus surgery (FESS) between October 1, 2007 and December 31, 2011 were recruited. Patient demographics, Lund-Mackay computed tomography (CT) scores, 22-item Sino-Nasal Outcome Test (SNOT-22) scores, disease characteristics, and medication use were collected prior to FESS. Intraoperative culture was obtained in a standard manner. We compared patients with isolates of S. aureus or P. aeruginosa to patients with other culture results and no bacterial growth, respectively. Multivariate logistic regression was performed. RESULTS: A total of 376 patients met criteria; 104 patients (28%) had S. aureus, 32 (9%) had P. aeruginosa, and 10 patients (3%) had no bacterial growth. After adjusting for all clinical factors, compared to patients with positive culture other than S. aureus, patients with S. aureus had 1.9 times increased odds of having nasal polyps (odds ratio [OR] = 1.9; 95% confidence interval [CI], 1.0 to 3.3; p = 0.036); when compared to patients with positive culture other than P. aeruginosa, patients with P. aeruginosa had 7.8 times increased odds of having prior FESS (OR = 7.8; 95% CI, 2.1 to 28.9; p = 0.002) (91% vs 58%; p < 0.001) and 3.6 times increased odds of having diabetes with marginal significance (OR = 3.6; 95% CI, 1.0 to 13.2; p = 0.053). The sample size in the no bacterial growth group was too small to draw firm conclusions. CONCLUSION: S. aureus was more common in CRS patients with nasal polyps, whereas P. aeruginosa was more common in CRS patients with prior FESS history and possibly diabetes.
