Application of special methods in diagnostics of benign and malignant mucosal lesions of upper aerodigestive tract.
Zábrodský, Michal ; Bouček, Jan (advisor) ; Čelakovský, Petr (referee) ; Šlapák, Ivo (referee)
Optical imaging methods incorporating observation of the mucosal surface of organs with narrowband filtered light are diagnostic tools with a significant development in recent years and have become an integral and inseparable part of the diagnostic process of benign and malignant pathologies of the mucosal surface of various anatomical systems of the human body. Malignant and premalignant lesions of the upper aero-digestive tract (UADT) are no exception. The present work demonstrates the benefits of evaluation of changes in microvascular architecture by narrowband imaging. Its major advantage is a more accurate diagnosis of premalignant and malignant mucosal pathologies in the head and neck region based on the identification of significant changes in superficial vascularity. There is a very strong correlation of these vascular changes with the final histopathological analysis. The present data have shown that videoendoscopic examination with narrowband imaging significantly improves the distinction between benign and malignant mucosal lesions even in the UADT pathologies with a similar tendency to neoangiogenesis (squamous cell papilloma vs. squamous cell carcinoma). It also refines the determination of surface extension of tumoral changes and helps to localize and accurately diagnose tumors of...
Clinical and nursing aspects of patients treated surgically for HPV-related ofopharyngeal tumours
Báťová, Linda ; Zábrodský, Michal (advisor) ; Jankovcová, Kateřina (referee)
Introduction: Oropharyngeal tumours belong to the most common malignancies situated in the head and neck area. In the past, their incidence has been associated with classical risk factors (smoking and alcohol use). In the recent years, the increase of oropharyngeal carcinomas resulting from HPV (human papilloma virus) infection incidence has been observed. The change of their aetiology also implies a number of clinical differences, the most important being a significantly better survival prognosis in patients with HPV+ carcinomas. Aims: The main goal of this thesis was to characterize correctly patients with oropharyngeal carcinomas and to identify different specifics of nursing intensive care for these patients. Methods: The quantitative prospective study involved 30 patients following their surgical treatment of oropharyngeal carcinoma, hospitalised in an intensive care unit. The patients were divided into 3 groups: HPV+ non-smokers, HPV+ smokers, HPV- smokers. Results: The study confirmed the demographic differences between individual patient groups. The HPV+ non-smokers group is characterized by a lower age in average, which is significantly reflected in a reduced duration of hospital stay. In addition, opioid administration rate, infection rates and postoperative complications incidences are...
