The use of pulse transit time in diagnostics of sleep-disordered breathing in children.

Introduction: Sleep is the physiological state of the body where proper morphology and duration are indispensable for human functions throughout both, physical and mental spheres. Disordered breathing during sleep impairs its morphology and results in major disorders in any age group. Adverse effects of Obstructive Sleep Apnea Syndrome in children and poor availability of centers offering children's polysomnography call for a reliable and easily accessible screening method.

Aim: The aim of this study was to evaluate the results of otosclerosis surgical treatment and to examine the impact of disease stage, time of the signs, age and sex on the results.

[Operation treatment results of laryngeal cancer in different types of partial laryngectomy based on own material].

The Aim: of the study was to evaluate the oncological results of laryngeal cancer treatment performed in the Laryngology University Ward in Zabrze in the years 1990-2000, depending on the type of partial surgery applied.

Materials And Methods: Retrospective clinical material includes 209 patients in whom surgery was a primary treatment method. No distant metastases (M1) or another malignant cancer were found.

[The influence of selected clinical and morphological factors on treatment results of patients with advanced cancer of the larynx].

Introduction: The aim of the study was to indicate independent prognostic factors of treatment in group of patients with advanced cancer of the larynx.

Material And Method: The paper presents results of univariate and multivariate analysis of selected clinical and morphological factors in the group of 355 patients with advanced laryngeal cancer treated in the ENT Clinical Department in Zabrze in the following years 1998-2007. The analysis of the results of treatment in relation to clinical and morphological features of the tumor was based on overall survival, disease-free survival, local control and locoregional control.

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.

[Postoperative vertigo caused by too long stapes prosthesis--radiological diagnostics].

The aim of the study was to describe the value of High Resolution Computed Tomography (HRCT) with MPR and VR reconstruction of the temporal bone in patients with persistent vertigo after stapedotomy. High Resolution Computed Tomography with MPR and VR reconstruction of the temporal bone in the axial and coronal planes with 0.625 - mm slice thickness were performed in 2 patients with persistent vertigo after stapedotomy.

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.

[The quality of voice in coal-miners after burn/inhalation injury due to methane explosion].

The job as a coal-miner exposes to the greatest risk. One of the most dangerous health hazard is a burn/inhalation injury during the methane explosion. The victims undergo physical trauma, effect of high temperature and inhalation of toxic gases and products of incomplete combustion, As a result of inhalation injury both, upper and lower airways are affected.

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.

[Imaging and assessment of glomus jugulare in MRI and CT techniques].

Introduction: Paragangliomas are rare group of tumors originating from paraganglionic tissue. The most common site of occurrence of the head and neck paragangliomas are: carotid body, jugular foramen (glomus jugulare) and tympanic cavity (glomus tympanicum). Magnetic resonance (MR), computed tomography (CT) and angiography are the modalities of choice in detecting and characterizing paragangliomas.

Assessment of hearing organ activity in a group of neonates with central nervous system impairment.

Objective: Hypoxic-ischemic encephalopathy, primary subarachnoid hemorrhage in term newborns as well as periventricular leukomalacia and intraventricular hemorrhage in premature newborns are the major consequences of perinatal asphyxia. Intrauterine hypoxia and labor prolongation can also affect the hearing organ in newborns causing reversible or irreversible changes in the cochlea, brainstem or cortex. The aim of the study was to carry out the objective assessment of the cochlea and hearing pathway activity using CEOAEs and ABR; to find relationships between hearing status and parameters effecting on nervous system in neonates with central nervous system impairment occurring following perinatal asphyxia.

[Long-term results of airways' injury after a methane explosion].

Injuries caused by thermal trauma more and more often affect people and they are an important problem of contemporary medicine. It is connected with the civilization development. Burn concerns not only the exterior integuments of the body but also airways, in those cases, the death rate among those who were injured with the thermal trauma increases.

[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.
