Predicting Severe Sleep Apnea in Patients with Complaints: Pulse Oximetry and Body Mass Index.

Objective: An adequate evaluation combined with an easily accessible test would be a useful way to direct the appropriate patients to sleep centers in circumstances with a limited opportunity for polysomnography (PSG). For this reason, it is necessary to use a screening method prior to PSG evaluation. The aim of the present study was to investigate whether the use of body mass index (BMI) and pulse oximetry is sufficient to predict the severity of obstructive sleep apnea syndrome (OSAS) without PSG.

Methods: The study was carried out on a total of 34 people with complaints of snoring, witnessed apnea and daytime sleepiness. 24-h pH monitoring with a two-channel, triple-sensor antimony pH catheter was applied to individuals simultaneously with polysomnography (PSG) on the day they would sleep in the sleep laboratory.

A Rare Complication of Chronic Otitis Media: Cerebellar Abscess.

Chronic otitis media (COM) and its associated complications are currently less common because of the popularity of imaging modalities such as computed tomography and magnetic resonance imaging and the increased use of antibiotics. Patients can be treated without any complications owing to early diagnosis. Despite all these new developments and opportunities, complications of autogenous cerebellar abscess may develop and be fatal.

Study Design: Case control study.

Setting: Tertiary health institution.

A new suggestion for the Epworth Sleepiness Scale in obstructive sleep apnea.

The aim of this study was to suggest a new cutoff score for the Turkish version of Epworth Sleepiness Scale (ESS) in the patients with obstructive sleep apnea. In this study, the data of 483 patients who were admitted to our clinic with the complaints of daytime sleepiness and witnessed sleep apnea were reviewed retrospectively. The correlation between ESS and polysomnography (PSG) findings were assessed, and cutoff score of the Turkish version of the ESS was investigated.

The Relation of the Obstruction Site on Muller's Maneuver with BMI, Neck Circumference and PSG Findings in OSAS.

We investigated relation of the site of obstruction detected on Muller maneuver (MM) with polysomnography (PSG) and physical examination findings.

A 54-year-old male patient presented to our outpatient clinic complaining of a mass under his chin, which appeared nearly 1 year earlier. Pathologic diagnosis was atypical lipomatous tumor. To the best of our knowledge, this is the first reported case to localize subcutaneously in the head and neck region.

The effects of merocel and glove finger tampon applications on the nasal septum mucosa of rabbits.

Objective: The use of tampons after nasal septum surgery is important for both prevention of postoperative bleeding and stabilization of the nasal flaps and the septum. One of the most important factors in achieving rapid postoperative recovery is the choice of the nasal tampon material, among many, to produce minimal damage on the nasal mucosa. In this study, the histopathological effects of the glove finger and merocel tampons, which are commonly used in clinical applications, have been investigated on the nasal mucosa of rabbits.

Meningoencephalocele as a rare cause of cerebrospinal fluid fistula during dacryocystorhinostomy.

A meningoencephalocele is a herniation of meninges and brain out of the cranial fossa through a bony defect. Cerebrospinal fluid leakage may occur due to a defect in the wall of the meningoencephalocele. The defect may be traumatic, iatrogenic, or may appear spontaneously.
