Auditory risk behaviours and hearing problems among college students in Serbia.

Aim: To investigate an association of auditory lifestyle and risk behaviours with hearing loss and to identify the leading hearing problems among college students in Serbia exposed to loud music.

Methods: The participants of the study comprised 780 college students of the High Medical School of Professional Studies of Belgrade (653 females and 127 males), the majority of whom were between 19 to 24 years of age. A cross sectional study was conducted in order to investigate the association between exposure to noise in one's leisure time and subsequent hearing problems using a self-reporting questionnaire.

Possible role of CD22, CD79b and CD20 expression in distinguishing small lymphocytic lymphoma from chronic lymphocytic leukemia.

Aim Of The Study: Flow cytometry has an important role in diagnosis and classification of B-cell lymphoproliferative disorders (BCLPDs). However, in distinguishing chronic lymphocytic leukemia (CLL) from small lymphocytic lymphoma (SLL) only clinical criteria are available so far. Aim of the study was to determine differences in the expression of common B cell markers (CD22, CD79b and CD20) on the malignant lymphocytes in the peripheral blood samples of CLL and SLL patients.

Primary nasal tuberculosis: a case report.

Introduction: During the past two decades, tuberculosis (TBC) both pulmonary and extrapulmonary, has emerged to be a major health problem. Nasal tuberculosis is a specific inflammatory process which is, in most cases, joined by the inflammation of neck lymph nodes.

Case Report: Thirty-year-old man presented with shortness of breath through the nose and periodical headaches.

Antrochoanal polyp of unusual size.

This paper presents antrochoanal polyp of unusually large size (8x5 cm), which we removed in a 34-year old patient by the antral portion by the Caldwell-Luc approach and the portion form the epipharynx through the oral cavity with skew pliers for the pharynx biopsy.

Risk factors for the appearance of minimal pathologic lesions on vocal folds in vocal professionals.

Background/aim: An excessive use or misuse of voice by vocal professionals may result in symptoms such are husky voice, hoarse voice, total loss of voice, or even organic changes taking place on vocal folds--minimal pathological lesions--MAPLs. The purpose of this study was to identify the type of MAPLs which affects vocal professionals, as well as to identify the risk factors that bring about these changes.

Methods: There were 94 vocal professionals who were examined altogether, out of whom 46 were affected by MAPLs, whereas 48 of them were diagnosed with no MAPLs, so that they served as the control group.

Factors influencing the choice of prescribed hearing aid.

In our paper we would like to emphasize the complexity of hearing aid prescription process. It is connected to a series of factors which impact the choice of hearing aid; type of hearing loss, degree of hearing loss according to the average hearing threshold expressed within the range from 500 Hz to 4000 Hz on a tonal audiogram, audiometric curve configuration, speech discrimination ability, patients' age at which the hearing impairment occurred, time elapsed between the occurrence of hearing impairment and prescription of a hearing aid, patients' age, physical and mental health and their cognitive function, anatomical characteristics of the auricle and external auditory canal, patient and parent motivation, cosmetic factors, financial abilities, cooperation with hearing aids manufacturers. This paper is important for everyday practice and can be used as a kind of guideline to the hearing aid prescription process.

Immunohistochemistry in diagnosis of extranasopharyngeal angiofibroma originating from nasal cavity: case presentation and review of the literature.

Angiofibromas are rare vascular tumors which originate predominantly in the nasopharynx and occur typically in male adolescents. Extranasopharyngeal sites such as nasal cavity and paranasal sinuses are less frequent. This review article was undertaken to evaluate the incidence, clinical features and management of extranasopharyngeal angiofibromas originating exclusivelly from nasal cavity structures.

[Sudden hearing loss: our experiences in treatment with vasoactive and corticosteroid therapy].

Introduction: Sudden hearing loss is a clinical entity of ambiguously defined aetiology manifested by hearing loss of more than 30 dB on three contiguous frequencies occurring within 72 hours. The lack of standard therapy protocol led to the use of variety of different therapies, thus making difficult objective quantification of their effect.

Objective: The aim of the study was to present our experience in the treatment of sudden hearing loss with administration of vasoactive and corticosteroid therapy.

Neonatal screening of hearing function by otoacustic emissions--a single center experience.

Background/aim: Nowadays development of techniques enables detection of hearing impairment in a very short time, immediately after birth by using otoacoustic emissions. They are low-pitched sounds produced in physiologically clear cochlea and can be recorded in cochlear outer meatus. By this method, complete data are found on a whole presynaptic auditory nervous system functioning that has mostly been affected by pathological changes making it a perfect screening test.

Ear injuries caused by parts of hearing aid.

This paper presents two cases of ear injuries caused by parts of hearing aids -a five-year old girl whose tympanic membrane was ruptured by a metal part of the earmold, and a patient with injury and inflammation of outer auditory channel caused by parts of a channel hearing aid. Aid amplifier could serve its purpose only if it is applied and handled with direct coordination with an ORL specialist.

[Condition of hearing sense and tinnitus before and after the treatment of otosclerosis].

Introduction: Otosclerosis is an osteodystrophy disease of the bony labyrinth of the ear which leads to stapes fixation and to bradyecoia of a conductive type. The microsurgical treatment by the use of a stapes prosthesis provides hearing improvement and a reduction or disappearing of tinnitus. The aim of our study was to determine the hearing condition and tinnitus before and after the treatment of otosclerosis.

[Subjective difficulties in young people related to extensive loud music listening].

Introduction: For human ear, noise represents every undesirable and valueless sound. In disco clubs, as in some other places with loud music mostly attended by young people, the level of noise sometimes attains over 100 dB. As reported by numerous studies, a high noise level could induce subjective difficulties (ear buzzing, audition loss, vertigo and palpitations, anxiety, high blood pressure, decreased concentration, lowered memory storing).

Total fixation of cricoarytenoid joint of a patient with rheumatoid arthritis and Hashimoto thyroiditis.

Introduction: The incidence of cricoarytenoid joint fixation in case of rheumatoid arthritis is 17 to 33%. In later stages of rheumatoid arthritis, a gradual fixation of cricoarytenoid joint develops and both halves of the larynx become less movable which calls for endotracheal intubation; while total fixation of this joint demands surgical tracheotomy. Hashimoto thyroiditis can display symptoms which are difficult to distinguish from the ones present in total fixation of cricoarytenoid joint caused by rheumatoid arthritis.

[Comparative analysis of audiometric and impedancemetric findings in workers exposed to the effects of various duration industrial noise].

Background/aim: Industrial noise is produced in workshops due to factory machinery and tools used in technological processes. It has detrimental effect to primarily the organ of the sense of hearing, thus damaging hearing in oversensitive subjects. The aim of the study was to perform a detailed analysis of audiometric and, especially, impedancemetric parameters in workers exposed to the effects of industrial noise of various duration, as well as to determine similarities and differences in workers with differences in sensitivity to damaging effects of noise.

[The comparative analysis of clinical symptomatology before and after the operation of otosclerosis].

Introduction: Otosclerosis is a progressive osteodystrophic disease of the osseous capsule of the labyrinth which leads to the fixation of the stapes and partial deafness. The progressive hearing loss followed by ear tingling--tinitus and vertigo is of great importance for this disease. The aim of the work was to determine the changes of clinical symptomatology before and after the operative treatment of otoscleoris.

[Sudden hearing loss--our experience in treatment with vasoactive therapy].

Introduction: A specific title "sudden hearing loss" refers to illness which is characterized by a sudden, rapid sensoneural hearing loss mostly in one ear without obvious causes, accompanied with dizziness, and without vestibular symptomatology. It is defined as a hearing loss for more than 30 dB on 3 or more successive frequencies which appear in 72 hours.

Objective: The main goal of our paper was to estimate success of implementation of vasoactive method in patients with sudden hearing loss of senso-neural type in different ranges in hospital conditions.

[Effect of noise on changes in the acoustic reflex].

Acoustic, stapedial reflex represents a response of the m. stapedius to a sonic excitation of supra speech intensity. It is the constitutive part of impendancmetric investigations, it is performed on the same apparatus after tympanometry, and it is the inseparable part in representation of impendancmetric findings.
