Quality of life assessment septoplasty in patients with nasal obstruction

Naasal obstruction is a common complaint in the population. When caused by a deviated nasal septum, septoplasty is the procedure of choice for treating these patients. NOSE is a tool for assessing the disease-specific quality of life related to nasal obstruction. Aim: To assess the impact of septoplasty on patients with nasal obstruction secondary to deviated nasal septum based on the disease-specific quality-of-life questionnaire. Design: Prospective. Methods: Patients undergoing septoplasty with/without turbinectomy after no clinical improvement with medical treatment were assessed by the NOSE questionnaire before and 3 months after surgery. We evaluated the surgical improvement based on total score, the magnitude of the surgery in the disease-specific quality of life and the correlation between the preoperative score and postoperatively improvement. Results: Fourty-six patients were included in the study. There was a statistically significant improvement in the preoperative NOSE score (md = 75, IQR = 26) and after three months (md = 10, IQR = 20) (p < 0.001.T-Wilcoxon). The standardized response mean was 3.07. We found a strong correlation between the preoperative score in the NOSE questionnaire and improvements in the postoperative period (r = -0.789, p < 0.001, Spearman). No difference was found in improvement scores by gender. (p = 0.668, U-Mann-Whitney). Conclusion: Septoplasty resulted in a statistically significant improvement in the disease-specific QOL questionnaire.

Prevalence of chronic rhinosinusitis in Sao Paulo

Introduction: Studies designed to investigate chronic rhinosinusitis (CRS) epidemiology play an important role to assess population's distribution and risk factors to result in the development and promotion of public health policies. Method: This study design is a survey carried out with a complex two-stage cluster sampling plan. Personal interviews were carried out with 2,003 individuals. The questionnaire included the epidemiological criteria for CRS. Demographic data, history of physician-diagnosed respiratory diseases (asthma, sinusitis, rhinitis), smoking, family income, educational attainment, and household characteristics were also evaluated. Results: The overall response rate was 93.9% of the households. Mean age was 39.8 +/- 21 years; 45.33% were male. The overall prevalence of CRS in the city of Sao Paulo was 5.51%. We found a significant association between diagnosis of CRS and diagnosis of asthma and CRS and diagnosis of rhinitis and a significant association between presence of CRS and belonging to the low-income subgroup. Conclusion: The municipality of Sao Paulo has an urban population of 11 million. According to the present study, the prevalence of CRS is 5.51%, which represents more than 500,000 individuals affected by this condition in the city.

Juvenile angiofibroma: major and minor complications of preoperative embolization

Introduction: Juvenile angiofibromas (JA) are highly vascular, benign tumours for which surgery is the treatment of choice. In most services, embolisation is performed prior to resection. Nevertheless, there are few data on the complications of preoperative embolisation for JA. Aim: To describe major and minor complications of preoperative embolisation in a 32-year experience of patients undergoing surgical resection of JA at a tertiary hospital. Methods: Retrospective chart review study of 170 patients who underwent surgical resection of JA at a tertiary hospital between September 1976 and July 2008. Results: All patients were male. Age ranged from 9 to 26 years. Ninety-one patients had no complications after embolisation. Overall, 105 complication events occurred of which four major and 101 minor. Conclusion: In our series, preoperative embolisation for JA produced no irreversible complications and no aesthetic or functional sequelae. The vast majority of complications were transient and amenable to clinical management.

Why do we not find polyps in the lungs? Bronchial mucosa as a model in the treatment of polyposis

The link between lower and upper airways has been reported since the beginning of 1800s. They share the same pseudostratified ciliated columnar epithelium lining and the concept of one airway, one disease is quite well widespread. Nasal polyposis and asthma share basically the same inflammatory process: predominant infiltration of eosinophils, mucus cell hyperplasia, edema, thickened basal membrane, polarization for Th2 cell immune response, similar pro-inflammatory mediators are increased, for example cysteinyl leukotrienes. If the lower and upper airways share a lot of common epithelial structural features so why is the edema in the nasal mucosa able to increase so much the size of the mucosa to the point of developing polyps? The article tries to underline some differences between the nasal and the bronchial mucosa that could be implicated in this aberrant change from normal mucosa to polyps. This paper creates the concept that there are no polyps with the features of nasal polyposis disease in the lower airway and through it is developed the hypothesis of the nasal polyps origin could partially lie on the difference between the upper and lower airway histology.

Giant cell bone lesions in the craniofacial region: a diagnostic and therapeutic challenge

Background: Giant cell tumors of bone (GCTs) are common in the long bones, but rare in the craniofacial region, with only 1% of cases occurring in the latter. Clinical, radiological, and anatomical diagnosis of this locally aggressive disease, which occurs in response to trauma or neoplastic transformation, poses a major challenge in clinical practice. Methods: The present study describes a series of 4 cases and highlights the main features of the differential diagnosis and treatment of these lesions: GCT, giant cell reparative granuloma (GCRG), and the brown tumor of hyperparathyroidism. Results: GCT presents as a benign neoplasm, most typically affecting the knees, and rarely in the temporal and sphenoid bones. It is radiologically indistinguishable from GCRG due to its lytic, poorly defined appearance. The distinction can only be made microscopically, as the presence of multinucleated giant cells scattered throughout the stroma and the absence of a history of trauma favor a diagnosis of GCT. The brown tumor of hyperparathyroidism occurs with rapid, localized osteoclast activity secondary to the effects of increased parathyroid hormone (PTH) levels; parathyroid examination is indispensable. Conclusion: The diagnosis and treatment of these lesions poses a major challenge due to their similar clinical presentation and radiological appearance. Accurate diagnosis is essential for definition of appropriate management, as complete resection is the goal in GCT and GCRG to avoid recurrence, whereas the brown tumor often yields to treatment of the underlying hyperparathyroidism.

Convergence of two major pathophysiologic mechanisms in nasal polyposis: immune response to Staphylococcus aureus and airway remodeling

This review is addressed two pathophysiologic mechanisms implicated in the pathogenesis of nasal polyposis: the unique remodeling process found in nasal polyp tissue and the immune response of patients with nasal polyposis to Staphylococcus aureus. These two theories converge to the same direction in different aspects, including decreased extracellular matrix production, impaired T regulation and favoring of a Th2 immune response. In patients with nasal polyposis, an exaggerated immune response to Staphylococcus aureus may aggravate the airway remodeling process.

Avaliação da qualidade de vida após sinusectomia endoscópica para rinossinusite crônica

A rinossinusite crônica é uma doença de etiologia não definida que impacta significativamente a qualidade de vida dos pacientes. A sinusectomia endoscópica foi demonstrada como um tratamento eficaz em melhorar a qualidade de vida dos pacientes em outros países; contudo, não existem estudos nacionais. OBJETIVO: Avaliar a associação cirurgia endoscópica nasossinusal com a qualidade de vida doença-específica dos pacientes com rinossinusite crônica com e sem polipose nasossinusal pelo SNOT-20. Desenho: Estudo prospectivo. PACIENTES E MÉTODOS: Pacientes submetidos à sinusectomia endoscópica após ausência de melhora ao tratamento medicamentoso foram avaliados pelo questionário SNOT-20p antes e 12 meses após a cirurgia. Avaliou-se a melhora na pontuação total e nos cinco itens considerados mais importantes por cada paciente. Avaliamos também a presença de correlação entre a pontuação pré-operatória e a melhora pós-operatória e se havia diferença entre a melhora segundo sexo. RESULTADOS: Incluímos 43 pacientes com idade de 44 (19), md (IIQ); e 60,5% (26/43) do sexo masculino. Os pacientes apresentaram melhora estatisticamente significativa no SNOT-20 e SNOT-20 (5+), e correlação entre a pontuação pré-operatória e a melhora da pontuação (p<0.001). Não houve diferença entre melhora da pontuação na qualidade de vida segundo o sexo. CONCLUSÃO: A sinusectomia endoscópica em pacientes com rinossinusite crônica apresenta associação com melhora da QV doença-específica estatisticamente significativa.
