Surgical Site Infection after Primary Open Surgery for Laryngeal Cancer in a Tertiary Hospital in Belgrade, Serbia: A 10-Year Prospective Cohort Study.

Background: Surgical site infection (SSI) in laryngeal cancer (LC) patients significantly increases morbidity and may postpone adjuvant therapy. Additionally, SSI can prolong hospitalization, thus representing a burden for the healthcare system. Most of the published studies refer to SSI after salvage laryngectomy.

Giant Fibrovascular Polyp as an Unusual Cause of Globus Pharyngeus.

Differential diagnosis of globus sensation in an otherwise asymptomatic patient should include hypopharyngeal fibrovascular polyp to avoid potentially fatal complications like airway compromise following regurgitation. We present a case of a 74-year-old man with a 13-cm long hypopharyngeal fibrovascular polyp with 9 months history of globus sensation. A narrow stalk of the giant polyp allowed endoscopic removal and complete resection with the CO laser.

Adaptation and Validation of the Voice Handicap Index (VHI)-30 into Serbian.

Objectives: To evaluate the internal consistency, test-retest reliability, and clinical validity of the Serbian version of the self-administered Voice Handicap Index (VHI)-30.

Study Design: Cross-sectional study.

Methods: The English version of VHI-30 was translated into Serbian and then back-translated into English.

Risk factors for surgical site infection in laryngeal cancer surgery.

Surgical site infection (SSI) is a significant factor of morbidity and mortality in patients surgically treated for laryngeal carcinoma. The aim of this prospective study in 277 patients was to determine the incidence of SSI in patients surgically treated for laryngeal squamous cell carcinoma and to identify risk factors for development of SSI. Patients with previous chemotherapy and/or radiotherapy were excluded.

Recurrent lipomatous tumor of hypopharynx: case report and literature review.

Liposarcoma is one of the most common soft-tissue sarcomas in adults, but head and neck are rarely involved, especially regions of the larynx and hypopharynx. According to Enzinger and Weiss, liposarcoma can be divided into 5 subtypes: well-differentiated, myxoid, round cell, pleomorphic and dedifferentiated. We present an unusual case of well-differentiated liposarcoma of the hypopharynx in a patient with previous three procedures of endoscopic removal of hypopharyngeal tumor classified as benign lipoma.

Congenital cholesteatoma of mastoid origin--a multicenter case series.

Background/aim: The mastoid is the rarest site for the onset of congenital cholesteatoma (CC). The symptoms are atypical and minimal. The aim of this multicenter retrospective descriptive study was to define this extremely rare condition and its clinical presentation, diagnosis and management.

[Rare extracranial localizations of the head and neck schwannomas].

Introduction: Schwannomas are tumors of neurogenic origin, that arise from Schwann cells which surround peripheral, cranial and autonomic nerves. Schwannomas account for only 5% of all benign soft tissue tumors, and 25-45% of extracranial schwannomas are present in the head and neck region. They are usually classified according to the nerve of origin and the site within the head and neck.

[Does acute sensorineural deafness befall to urgent conditions?].

Background/aim: Idiopathic sudden sensorineural hearing loss (ISSHL) is one of the most controversial issues in otology. The aim of this study was to determine whether a delay in treatment has any influence on hearing recovery in ISSHL.

Method: This study was designed as a retrospective evaluation of an electronic patient data base of the University Hospital Zürich from January 1995 to August 2006.

Incidence of age related macular degeneration in correlation with age, sex and occupation.

This study assesses the relation between age related macular degeneration (ARMD) and age, sex and occupation. It is designed as a retrospective study conducted on patients presenting to the Eye Polyclinic "Dr. L.

[Significance of ultrasound and ultrasound-guided fine-needle aspiration for the detection of laryngeal occult metastases].

Background/aim: To evaluate ultrasound criteria based on a node size, shape, vascularity and cytology findings with respect to their value for the comparative determination of metastatic lymph nodes in laryngeal carcinoma.

Methods: A prospective study included 30 patients with laryngeal squamous cell carcinoma without node enlargement on computerized tomography, at the Department of Otorhinolaryngology, the University Hospital, Zemun. Thirty-six neck lymph nodes were evaluated sonographically and aspirated with an ultrasound-guided fine-needle.

The difference in complex psychomotor reaction time between patients with and without signs of cerebral circulatory disorders.

On a sample of 65 subjects rheoencephalography (REG)--the electrical impedance plethysmographic method for assessment of cerebral circulation was applied, as well as an electronic psychodiagnostic instrument Complex Reactionmeter Drenovac (CRD) constructed for assessment of complex psychomotor reactions. The aim of this study was to evaluate the potential differences between subjects with and without signs of cerebral circulatory disorders with regard to speed, stability and accuracy of complex psychomotor reaction. The results revealed that variable "maximal speed" on CRD showed significant difference between the groups, in favor of the control group.

Complex reaction time and EEG characteristics in alcoholics.

In a group of 88 male alcoholics a psychodiagnostic electronic series CRD test (Complex Reactiometer Drenovac) was applied and electroencephalograms (EEG) were recorded. Results showed a relationship between the frequency of the basic rhythm in the EEG finding and rapid, accurate reactions at the CRD 4-A test. A positive relationship was also found between the satisfactory blocking of the basic rhythm by eye opening and faster and more accurate reactions at the same test.

Cervicobrachial syndrome--work and disability.

The subjects in the study were 114 persons receiving a disability pension or referred for disability assessment. They were placed in two groups of 57 persons each, one with marked cervicobrachial syndrome and the other without. The latter group was chosen by the method of equivalent pairs with regard to sex and age.

[Changes in the anterior segment of the eye in workers in the coke manufacturing industry].

An investigation carried out of eye disorders in workers employed in the manufacture of coke demonstrated a high percentage of changes in the anterior segment of the eye. Registered symptoms such as conjunctival hyperemia, pinguecula, pigmentation and conjunctivitis were most probably connected with specific work and exposure to coal dust and irritants. In workers exposed for less than two years there were no changes in lacrimal secretion.

[Lacrimal hyposecretion in women working with video terminals].

Tests of vision and lacrimal secretion were performed as part of a general medical check-up among women employed at video-terminals in a bank. The tests were taken by three groups of 100 employees each. The first group consisted of full-time (eight hours) employees, the second of those working part-time (the time spent at a video-terminal daily was never less than two hours of continuous work) and a third group of control subjects having different clerical jobs but working in the premises with video-terminals.
