OBJECTIVE To investigate the presence of Chlamydophila pneumoniae and other bacterial pathogens in middle ear effusion samples obtained from children with otitis media with effusion (OME). MATERIALS AND METHODS Twenty-eight children (mean age 7.03; standard deviation 2.18) with OME unresponsive to medical therapy were included in the study. All of the children underwent ventilation tube insertion under general anesthesia. Eighteen patients were bilaterally affected whereas 10 children had unilateral disease. The middle ear fluids (46 samples in total) were collected during ventilation tube insertion, and were evaluated subsequently for the presence of C. pneumoniae and other bacterial pathogens using polymerase chain reaction (PCR). RESULTS Although all samples were negative for C. pneumoniae, bacterial DNA was detected in 21 of 46 samples. Overall 40% of the patients (4/10) with unilateral involvement, and 61% of the patients (11/18) with bilateral involvement were positive for bacterial DNA. In 6 patients with bilateral OME bilateral samples were positive, whereas 5 patients with bilateral OME showed only unilateral positivity. According to the results of DNA sequencing analysis, all of the positive samples harbored only one bacterial species. In 12 of 46 samples Alloiococcus otitidis DNA (26%), in 7 Haemophilus influenzae DNA (15%), in one Streptococcus pneumoniae DNA (2%) and in one Moraxella catarrhalis DNA (2%) were present. CONCLUSIONS Our findings support that C. pneumoniae does not seem to have a role in OME in children whereas A. otitidis was found to be more frequent than the other common pathogens. Further studies are required to elucidate the exact pathogenetic role of these microorganisms in OME.

Hydatid cyst is a cyclozoonotic infection caused by the cestode Echinococcus granulosus. Hydatid cyst in the head and neck region is very rare, even in countries where echinococcus infestation is endemic. We report the case of a 17-year-old male patient presenting with a hydatid cyst in the parapharyngeal and neck region. There was no pulmonary or hepatic involvement. The definitive therapy comprised excision of the cystic mass and postoperative medical treatment.

Congenital stridor is rare. The most common presentation for congenital stridor is chronic loud breathing since birth. It is noticed in patients by the first 4 to 6 weeks of life. There are many causes of congenital stridor. Laryngomalacia is the most common cause of congenital stridor. Congenital vocal cord paralysis is the second most common cause of congenital stridor. Vocal cord paralysis in infants and children can be either congenital or acquired and either unilateral or bilateral. Although most commonly the paralysis is idiopathic, there are many causes of acquired vocal cord paralysis. Arnold-Chiari malformation is the most common congenital central nervous system abnormality resulting in vocal cord paralysis, and central nervous system abnormalities usually may cause bilateral vocal cord paralysis. In this article, we report 2 patients with idiopathic congenital vocal cord paralysis. One of them has the unilateral vocal cord paralysis, and the other, bilateral.

First branchial cleft is the only branchial structure that persists as the external ear canal, while all other clefts are resorbed. Incomplete obliteration and the degree of closure cause the varied types of first branchial cleft anomalies. They were classified based on the anatomical and histological features. We present an unusual type of first branchial cleft anomaly involving the external auditory canal, the middle ear and the nasopharynx through the eustachian tube.
