“…They can even be clinically silent. 5 In our study we found nasal obstruction (87%) and nasal discharge (71%) to be the most common symptoms of patients with nasal polyps. Other symptoms were sneezing, snoring, headache, loss of smell as in Table 3.…”

Background: Nasal polyps are common nasal disorders with unknown etiology and high recurrence and high prevalence of 1-4% which affect the quality of patient life. The aim of the study was to find out the prevalence of nasal polyps in our hilly region and find out its etiological or risk factors for better prevention and cure of the disease.Methods: 60 patients with nasal polyps were included in this study and were assessed for age and sex distribution, types of polyps, main clinical symptoms and their duration, their major etiological or risk factors through detailed history taking, physical and nasal examination, anterior and posterior rhinoscopy, diagnostic nasal endoscopy and computerized tomography scan. Results: Nasal polyps are more common in males and in middle age group. Most of the common types are bilateral and ethmoidal polyps. Most of the patients were symptomatic with nasal obstruction and nasal discharge as main symptoms. There was strong correlation between nasal polyps and recurrent nasal infection, allergy and asthma. In this region we found familial inheritance of this disease and high rate of polyp recurrence after medical or surgical therapy.Conclusions: Nasal polyps are common in hilly region with high rate of recurrence with nasal infection, allergy and asthma being the important etiological factors.

“…Por otra parte, la presencia de PN puede venir acompañada de la sintomatología propia de los mismos o, por el contrario, de forma silente, siendo este último tipo de pólipos de carácter permanente o transitorio. Este hecho implica que existe una clase de pacientes en los que no se contempla la existencia de PN hasta que son descubiertos mediante exploración clínica [16]. A estos pacientes que por carecer de sintomatología no son propensos a diagnosticarles la existencia de PN se debe añadir el hecho de que aproximadamente un tercio de los pacientes sintomáticos de la enfermedad no solicitan atención médica al aparecer los síntomas nasosinusales [17].…”

Rhinosinusitis is an inflammatory and obstructive process that affects the nasal cavity and sinuses. It's called chronic rhinosinusitis (CRS) when the disease lasts beyond 12 weeks. CRS can be associated with nasal polyps (CRSwNP) or not (CRSsNP). CRSwNP is a disease with high morbidity characterized by the existence of neoplastic structures that cause airways obstruction. Polyps are formed by the infiltration of inflammatory cells. Current treatments are ineffective in many of the patients having to undergo repeated surgical procedures therefore the developing of new and more effective drugs are necessary. Research in animal models is currently limited by the lack of diagnostic and disease monitoring methods without sacrificing animals. This study evaluates the effectiveness of the analysis of images carried out by computed tomography (CT) and positron emission tomography (PET) techniques in the diagnosis and monitoring of CSR-PN in an animal model. This animal model of the disease was obtained by an instillations protocol with ovalbumin as a sensitizer and Staphylococcus aureus enterotoxin B as inducing agent. CT technique is based on the ability of penetration of x-rays for detecting changes in tissue density. PET technique has the ability to calculate the glucose uptake by a homologous radiolabel. Tissue density and glucose uptake are properties that are altered in the course of a severe inflammatory process. The results obtained confirm the validity of these techniques to determine the existence of an inflammatory process and neoplastic structures in the developed disease model. The results obtained by the histological post-mortem analysis techniques corroborated this conclusion. It can be said that the use of CT and PET techniques is an effective method for determining and monitoring the evolution of CSRwPN in animal models in vivo, allowing the research into effective treatments for the disease. AgradecimientosEste trabajo es posible gracias a Xavi, quien creyó desde un primer momento que yo era la persona indicada para llevarlo a cabo y siempre sacó un momento para guiarme y aconsejarme en cada uno de los pasos de su realización.Mi agradecimiento, también, a los compañeros de la Fundación, que tanto me han ayudado a conseguir terminar un proyecto tan largo como este, en el tiempo estipulado, permitiéndome compaginarlo con el curso, así como prestándome su ayuda incondicional cuando me surgía alguna duda o me faltaba algún dato para poder seguir avanzando.A Rafa por ofrecerse a tutorizar este trabajo, permitiéndome poder desarrollarlo y defenderlo ante un tribunal.Por supuesto necesito también agradecer su apoyo a mi familia y amigos, especialmente a mi madre y a mi novia, Inma, pues sin su ayuda me hubiera sido mucho más difícil avanzar durante este largo periodo de trabajo, animándome siempre, ayudando cuando podían hacerlo y recordándome que a veces lo mejor para seguir a delante es despejarse un poco.Por último quiero dar gracias a mi padre por enseñarme, junto a mi madre, a ser lo que soy ho...
