Unintentional conversion of benign paroxysmal positional vertigo caused by repositioning procedures for canalithiasis: transitional BPPV.

BPPV when diagnosed before any repositioning procedure is called primary BPPV. Primary BPPV canalithiasis treatment with repositioning procedures sometimes results in unintentional conversion of BPPV form: transitional BPPV. Objectives were to find transitional BPPV forms, how they influence relative rate of canal involvement and how to be treated.

Small cell neuroendocrine tumor of the larynx--a small case series.

Neuroendocrine tumors are the most common nonsquamous types of laryngeal neoplasms. They are classified as typical carcinoids, atypical carcinoids, small-cell neuroendocrine carcinomas, and paragangliomas. The aim of the paper is to present four patients with small-cell neuroendocrine tumor arising in larynx.

Voice quality after treatment of early glottic carcinoma.

Objectives: Increasing incidence of laryngeal carcinoma and advancement in diagnostics and therapy methods, have led to constant exploration in that field. Early glottic carcinoma can be treated successfully with several procedures: cordectomy through laryngofissure, laser cordectomy, and radiotherapy. Our objective was to assess the voice quality after these different modalities of treatment.

Risk factors for the occurrence of undifferentiated carcinoma of nasopharyngeal type: a case-control study.

Introduction: The incidence rate of nasopharyngeal carcinoma in Serbia is less than one per 100,000 citizens, which classifies it as a region with low incidence for this disease.

Objective: The aim of this study was to test some hypotheses of the risk factors for undifferentiated carcinoma of nasopharyngeal type (UCNT) in the low incidence population.

Methods: A case-control study was used for the research.

Enzymatic study of tonsil tissue alkaline and acid phosphatase in children with recurrent tonsillitis and tonsil hypertrophy.

Objective: Indications for tonsillectomy in recurrent tonsillitis are defined according to the number of episodes of acute bacterial infections in a year. However, little is known about the tonsil immune competence status in patients presenting with recurrent tonsillitis with either hypertrophied or atrophied tonsils, or in patients presenting with obstructive sleep apnoea. In this study we examined the tonsil immune status in children with 3-5 acute recurrent infections a year and in children with obstructive sleep apnoea by comparing the activity of tonsil and adenoid tissue nonspecific alkaline and acid phosphatase.

The aim of this descriptive study was to analyze NPC incidence in Belgrade (the capital city of Serbia, with about 1.

Gastroesophageal reflux disease correlation with posterior laryngitis.

Background/aim: Over the last years numerous studies have been performed dealing with mutual relations among gastroesophageal reflux disease (GERD) and numerous diseases of the upper airways. The aim of the present study was to establish possible causal relationship between GERD and posterior laryngitis (PL).

Methods: The study included 103 patients with gastrointestinal complaints.

Overlooked nasal foreign body with a 48-year latent period.

Foreign bodies of the nose are relatively frequent in pediatric population, while in the adults, they are usually seen in disturbed persons. Overlooked nasal foreign bodies may be singled out as a special entity. They become rhinolites over time with latent period of several decades.

Protease activities of Candida spp. isolated from otitis externa: preliminary result.

Otomycosis is a fungal infection of the ear predominantly caused by Candida and Aspergillus spp. The possible virulence factors of Candida spp. are enzymes, such as proteases, phospholipases, phosphatases and esterase.

The analysis of clinical characteristics of the chronic rhinosinusitis: complicated and uncomplicated form.

The objective of our study was to analyze the intensity of subjective symptoms and objective findings of endoscopy and CT scanning in chronic rhinosinusitis, in the groups with and without nasal polyps. To evaluate the intensity of subjective symptoms visual analogue scale (VAS) was used, while scores were obtained by adding grades. Endoscopic finding was given in scores recommended by Lanza and Kennedy and CT results were presented by Lund-Mackay scoring system.

Selective neck dissection for cervical node negative supraglottic carcinoma.

Purpose: To investigate the incidence, localization, correlation to primary tumour and therapeutic results in supraglottic carcinoma patients with occult metastatic neck nodes.

Patients And Methods: The study included patients with supraglottic laryngeal carcinoma treated in the period 1976-1993. They all had clinically negative findings in the neck (N0) and had undergone primary surgery with curative intent.

Conductive hearing loss in patients with active acromegaly.

Objective: There have been rare conflicting results reported concerning possible higher frequency of hearing loss in acromegalic patients. Our goal was to determine whether there is higher frequency of conductive hearing loss in acromegalics and what may cause it if there is any.

Study Design: Prospective study.

Stomal recurrence after primary total laryngectomy.

Stomal recurrence after total laryngectomy is usually considered to be incurable. A total of 402 patients suffering from squamous cell carcinoma of the larynx treated by total laryngectomy during the period 1982-96 were analysed. In the group of patients studied, the significant risk factors for stomal recurrence were glottic-subglottic tumour localization and regional tumour spread.

[Clinical characteristics of the tympanic membrane retraction pocket].

Development of the eardrum retraction pocket, as pathologic finding, depends on Eustachian tube dysfunction, onset of the middle ear infection and site of development of retraction on the eardrum. The study is aimed at: 1. Determining the incidence of eardrum retraction pocket and cholesteatoma within it, as well as at the degree of eardrum retraction; 2.

[Juvenile angiofibroma of the nasopharynx--clinical diagnosis and therapy].

Juvenile nasopharyngeal angiofibroma is an infrequent epipharyngeal tumour necessitating particular diagnostic and therapeutic procedures in comparison to other benign epipharyngeal tumours due to its expansive growth tendency. Our retrospective study is aimed at presenting clinical casuistry of the tumour in order to evaluate modern diagnostic and therapeutic possibilities. The study included 13 male patients, aged 13-24 years, who were hospitalized, diagnostically assessed and surgically treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia over the period 1990-June 2001.

[Rhabdomyosarcomas in the naso-paranasal area].

The nasoparanasal region rhabdomyosarcoma belongs to the group of the rare malignant diseases, however it nevertheless represents major diagnostic and therapeutic problem. The study is aimed at presenting clinical casuistry of the nasoparanasal region rhabdomyosarcoma in adults and children, for the purpose of assessment of modern diagnostic and therapeutic possibilities. The study was retrospective and included the patients with evidenced and pathohistologically verified rhabdomyosarcoma of the nasoparanasal region diagnosed and treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery of the Clinical Centre of Serbia, during the period 1988-2001, and subsequently at the Institute of Oncology in Belgrade.

Chronic inflammation of the middle ear is the most frequent cause of otogenic complications. Meningitis is the most frequent otogenic intracranial complication, followed by otogenic brain abscesses, while other complications are significantly less frequent. The study is aimed at presenting clinical causitry of otogenic brain abscesses consequential to chronic suppurative otitis in order to evaluate modern diagnostic and therapeutic possibilities.

Fibrous dysplasia of the temporal bone and maxillofacial region associated with cholesteatoma of the middle ear.

Fibrous dysplasia of the temporal bone is a rare disease which may lead to progressive stenosis of the external auditory canal and the development of cholesteatoma. We present a case in which minimal symptoms were present despite a massive temporal bone fibrous dysplasia. Cholesteatoma resulted most probably secondary to external auditory canal stenosis.

Altered immunoregulations in otosclerosis: presence of autoantibodies in otosclerotic sera samples.
