Sialic acids in squamous cell carcinoma of the head and neck.

Altered glycosylation is a universal characteristic of cancer cells, and various types of glycan structures are well‑known markers of tumor progression and invasion. The present article discusses this aspect of the role of sialic acid, biosynthesis of sialylglycoconjugates and the genetic basis of its disorder, as well as the effects and the correlation between altered sialylation and clinical prognosis in head and neck squamous cell carcinoma (HNSCC). Only a few studies concerning the level of sialic acid in head and neck tumors have been conducted so far.

Material And Methods: Forty-two patients (19 females, 23 males) aged 34-73 years (55 ±12.

Comparative assessment of the voice in patients treated for early glottis cancer by laser cordectomy or radiotherapy.

Introduction: Adaptation of laser surgery in laryngeal cancer treatment in 1970s led to great successes and common acceptation of this treatment method in cancer treatment. The results of cancer treatment with CO(2) laser are the same as after radiotherapy or external access method.

Material And Methods: The study included 63 patients treated for glottis cancer T1.

Current view on nasal polyps management in Samter's triad patients.

Unlabelled: The nasal polyps associated with Samter's triad are often very extensive, difficult to treat, with great tendency to recurrence. In this paper the current opinion on nasal polyps management in aspirin triad patients was presented.

Pathogenesis: Opinions on pathogenesis of these disease was remembered as well as its epidemiology.

The presence of fungal floras in sinuses in chronic sinusitis patients with polyps.

Several fungal species are known to cause severe respiratory and cutaneous diseases. The aim of this work was to analyze the fungal flora in maxillary sinuses in patients suffering from chronic sinusitis with polyps. Twenty five patients (11 woman, 14 man) who underwent endoscopic surgical procedures were included into the study.

An updated view on tuberculous lymphadenitis in the context of HIV epidemic as well as multidrug and extensively drug-resistant tuberculosis.

Background: An updated view on tuberculous lymphadenitis was presented in this paper.

Objectives: This article describes tuberculous lymphadenitis as the most common presentation of extrapulmonary tuberculosis and reviews its epidemiology, clinical aspects, diagnosis and treatment methods. The role of surgical procedures was also underlined.

[Usefulness of laser arytenoidectomy and laterofixation in treatment of bilateral vocal cord paralysis].

Introduction: Bilateral vocal cord paralysis is caused by the damage of both recurrent laryngeal nerves. Such a pathology is not commonplace in the ordinary medical practice. It most often occurs as a complication after the thyroid gland surgery or thyroid re-surgery.

Reconstruction of the larynx after a resection of a huge chondrosarcoma.

Chondrosarcoma of the larynx is a rare condition of still unknown pathogenesis. This tumor occurs usually between the sixth and seventh decade of life. Forty five years old patient was admitted to the ENT Department in Zabrze for a diagnosis of a slow growing tumor from about 3 years.

Protective effect of intermittent clamping of the portal triad in the rat liver on liver ischemia-reperfusion injury.

Background: Intermittent clamping (IC) of the portal triad is an effective method of protecting the liver from ischemia-reperfusion injury (IR). In clinical practice, this method is employed during a resection, but its mechanism is still not clear.

Objectives: To evaluate the effect of IC on rat liver and determine its mechanisms.

Exhaled nitric oxide in patients with early glottic cancer.

Nitric oxide (NO) may contribute to the mutagenic processes and has been extensively studied as a noninvasive marker of neoplastic processes occurring in the airways. It has been suggested that an increased expression of inducible NO synthase might appear as an important molecular event involved in the early stage of laryngeal carcinogenesis. The aim of this study was to determine NO levels in the exhaled air of patients with early stage glottic carcinoma.

[Efferent suppression test--sensitivity and specificity].

Introduction: The amplitude of click evoked otoacoustic emissions can be suppressed (reduced) with contralateral acoustic stimulation (CAS). This is thought to be due to the inhibitory control that the medial efferent auditory nerve exerts on outer hair cell function. One commonly used test of medial olivocochlear (MOC) function in humans involves measuring the degree of suppression of ipsilateral otoacoustic emissions (OAEs) by CAS.

[Abscess of the parapharyngeal space].

The abscess of parapharyngeal space is very dangerous health condition graving numerous complications such as: jugular vein thrombosis, mediastinitis, arterial bleeding. This state originates most frequent during the acute pharyngitis, and especially acute tonsillitis. The aim of our study was to review the clinical sings, computed tomography scans and outcome of parapharyngeal space infection.

[Biodegradation of tracheal carbon implant in animal experiment].

Introduction: The radical treatment of tracheal stenosis comprises segmental resection and its reconstruction. The most successful type of reconstruction is the "end to end" technique. In cases with large tracheal defects (over 6 cm) this kind of reconstruction is impossible.

[Functional results after the treatment of laryngeal stenosis].

Unlabelled: Six subjects before and after surgery because of the laryngeal stenosis were presented. In 3 cases laryngeal web was recognised which arises after endoscopical removal of infant papilloma. The scar after laser chordectomy due to carcinoma of the larynx occurred in remaining 3 patients.

[Study of selected biomaterials for reconstruction of septal nasal perforation].

Introduction: The septal nasal perforation is an important problem for the laryngologists and plastic surgeons. The reasons of septal nasal perforations are injuries, neoplasm, self-mutilation, chronic rhinitis, allergy, Wegener granuloma, sarcoidosis, tuberculosis, toxic metals (arsenic, chrome), some drugs (steroids), narcotizing agents (cocaine) and complications after endoscopic and septal nasal operations. The surgical treatment, especially in the cases of large septal perforation, is often difficult because of the atrophy of nasal mucosa and lack of suitable material for reconstruction.

[Surgical treatment of chronic sinusitis in children].

Introduction: Chronic sinusitis presents important problem in children. General approach in chronic sinusitis in children consists of: findings the proper diagnosis, optimal pharmacotherapy (oral or intravenous antibiotics), treatment coexisting allergic or systemic diseases and considering employing surgical treatment. The main surgical procedures in the treatment of chronic sinusitis in children are adenoidectomy and functional endoscopic sinus surgery (FESS).

Introduction: Chronic sinusitis with nasal polyps is very often associated with allergy. The results of surgical treatment (Functional Endoscopic Sinus Surgery--FESS) in this group of patients are different and rather poor, especially in long term observations.

The Aim: of our study was to evaluate the results of surgical treatment (FESS) in patients suffering from chronic sinusitis with nasal polyps associated with allergy.
