Polish national guidelines for the diagnosis and treatment of chronic otitis media with effusion in children.

Otitis media with effusion (OME), is a common childhood disease and is characterized by long-term fluid retention in the middle ear spaces without signs of acute infection. Surgical treatment of OME in the form of a tympanostomy is one of the most commonly performed medical procedures by pediatric ENT surgeons worldwide. In February 2022, the Journal of Otolaryngology - Head and Neck Surgery published updated guidelines from the American Academy of Otolaryngology - Head and Neck Surgery for tympanostomy tuba in children between 6 months and 12 years of age.

The analysis of Treg lymphocyte blood percentage changes in patients with head and neck cancer during combined oncological treatment: a preliminary report.

Introduction: In patients with cancer, Treg lymphocytes seem to play an important role in promoting tumour growth. The number of circulating Treg cells has been associated with poor survival among patients suffering from various types of cancers. The aim of the present study was to evaluate the changes in the percentage levels of Treg lymphocytes in the blood samples of patients with head and neck cancer during combined treatment with respect to the stage of the disease and the intensity of the radiation reaction as monitored using the Dische scale.

The influence of chain microstructure of biodegradable copolyesters obtained with low-toxic zirconium initiator to in vitro biocompatibility.

Because of the wide use of biodegradable materials in tissue engineering, it is necessary to obtain biocompatible polymers with different mechanical and physical properties as well as degradation ratio. Novel co- and terpolymers of various composition and chain microstructure have been developed and applied for cell culture. The aim of this study was to evaluate the adhesion and proliferation of human chondrocytes to four biodegradable copolymers: lactide-coglycolide, lactide-co-ε-caprolactone, lactide-co-trimethylene carbonate, glycolide-co-ε-caprolactone, and one terpolymer glycolide-colactide-co-ε-caprolactone synthesized with the use of zirconium acetylacetonate as a nontoxic initiator.

Prevalence and risk factors for auditory neuropathy spectrum disorder in a screened newborn population at risk for hearing loss.

Objective: To determine the prevalence of Auditory Neuropathy Spectrum Disorder (ANSD) among infants with sensorineural hearing loss (SNHL) and discuss the risk factors.

Methods: The study group was comprised of children diagnosed with ANSD. Criteria for inclusion in the study group were as follows: permanent sensorineural hearing loss (SNHL); normal transient evoked or distortion product OAEs; absent or elevated middle-ear muscle reflexes (MEMR); severely abnormal or absent ABR waveform.

Otogenic lateral sinus thrombosis in children.

Objective: To present the results and experience with diagnosis and treatment of lateral sinus thrombosis, as a complication of otitis media, in a pediatric population.

Patients: Five children, 2 girls and 3 boys, with age ranging from 3 to 9 years, identified as having otogenic lateral sinus thrombosis confirmed with clinical symptoms and radiologic findings.

Intervention: All patients underwent canal wall intact mastoidectomy with tympanostomic tube insertion.

Risk factors associated with hearing loss in infants: an analysis of 5282 referred neonates.

Objective: The aim of our study was to evaluate the frequency of risk factors and their influence on - the distribution and manifestation of - hearing loss in infants. The study was conducted at the Department of Laryngology in the Upper Silesian Center for Child Health in Katowice (Poland), as part of the Polish National Universal Neonatal Hearing Screening, conducted from 2003 to 2009.

Materials And Methods: The selected population included every newborn that twice tested positive on the transient evoked otoacoustic emission (TEOAE) screening test, as well as all neonates with one or more risk factors as defined by the Joint Committee of Infant Hearing in 2000 (JCIH).

Single-stage laryngotracheoplasty in children.

Objective: To review the outcomes of pediatric patients with laryngotracheal stenosis treated by single-stage laryngotracheoplasty.

Methods: A single surgeon personal series retrospective review of 15 children undergoing single-stage laryngotracheoplasty for laryngeal stenosis over 4-year period (2004-2008).

Results: 15 patients (9 boys and 6 girls), with ages ranging from 1 month to 18 years, were operated.

[Hearing assessment of children treated with Cisplatin].

The Aim Of The Study: Cisplatin's effect on the inner ear in children and compare results of the tonal audiometry and the oto-acousitic emission audiometry.

Material And Methods: Audiological examinations were conducted on 33 children who had been treated with Cisplatin. Normal hearing prior to the cytostatic therapy would qualify a child for inclusion in the examinations.

Intralesional injection of cidofovir for recurrent respiratory papillomatosis in children.

Introduction: Papillomatosis of the larynx appears as the result of an infection by the human papilloma virus (HPV). In children, the disease produces benign lesions, which grow rapidly and show a marked tendency to recur once removed. The course of the disease is unpredictable.

[Cemento-ossifying fibroma--case report and review of the literature].

Authors report two cases of benign, osteogenic neoplasms of the maxilla in children which defined as cemento-ossifying fibroma and juvenile cemento-ossifying fibroma. Difficulty in diagnosis of the tumor is indicated. The importance of clinical data as well as radiology and histopathology examination for a proper diagnosis is indicated.

[Infratemporal teratoma--case report].

A newborn infant with rare teratoma of infratemporal fossa is presented. This neoplasm develops in childhood or early adulthood, generally in gonads. 10% of all teratomas are tumors of head and neck.

[Solitary neurofibroma of the nose--case report].

Neurofibroma is a tumor rarely found arising in the head and neck region. A rare case of solitary neurofibroma of the nose in a 2 years old child is presented. Tumor after delivery was observed.

[Mucoepidermoid carcinoma of the larynx].

Mucoepidermoid carcinoma is classified among the salivary gland tumors and is commonly found in the parotid gland. In the larynx it is an uncommon tumor that occurs mostly in men. There have been only about 100 cases of laryngeal mucoepidermoid carcinoma reported in the literature.

[The evolution of threshold values of air conduction in the extended high frequency range (9-18 kHz) in patients suffering from the pulmonary tuberculosis treated with combination of SM, INH, RFM, and PZA].

The evolution of threshold values of air conduction in the extended high frequency range (9-18 kHz) at patients suffering from the active pulmonary tuberculosis treated with the combined therapy (SM, INH, RFM, PZA). There were audiologically examined 13 patients (the average age 41.2) suffering from the active pulmonary tuberculosis and treated with the combined therapy (SM, INH, RFM, PZA).
