Effects of sleep deprivation on anaerobic exercise-induced changes in auditory brainstem evoked potentials.

Background: The present study was designed to assess how anaerobic exercise affects auditory brainstem response (ABR) parameters, and whether one night of sleep deprivation could alter these possible exercise-induced changes in ABRs.

Methods: Seven healthy, audiologically normal male students (mean age 22.4 +/- 1.

Sleep deprivation induced anxiety and anaerobic performance.

The aim of this study was to investigate the effects of sleep deprivation induced anxiety on anaerobic performance. Thirteen volunteer male physical education students completed the Turkish version of State Anxiety Inventory and performed Wingate anaerobic test for three times: (1) following a full-night of habitual sleep (baseline measurements), (2) following 30 hours of sleep deprivation, and (3) following partial-night sleep deprivation. Baseline measurements were performed the day before total sleep deprivation.

[The protective effect of oral magnesium supplement on noise-induced hearing loss].

Objectives: We investigated the beneficial effect of magnesium in the prevention of noise-induced cochlear damage in guinea pigs by transient evoked otoacoustic emissions (TEOAE).

Study Design: Thirty-nine guinea pigs with normal auropalpebral reflex were randomly divided into control (n=20) and study (n=19) groups. All the animals were subjected to wide-band noise standardized at a mean of 98+/-2 dB for 16 hours a day for 10 days in a sound isolated cabin.

[Evaluation of the protective effect of magnesium on amikacin ototoxicity by electrophysiologic tests in guinea pigs].

Objectives: This experimental study was performed to evaluate the protective effect of magnesium on amikacin ototoxicity.

Study Design: Twenty-seven guinea pigs (54 ears) with normal auropalpebral reflexes and otomicroscopic examination, auditory brain stem responses (ABR), and transient evoked otoacoustic emissions (TEOAE) were randomly divided into four groups to receive amikacin once 15 mg/kg daily (group 1 and 3) and twice 7.5 mg/kg daily (group 2 and 4) for seven days.

Positive effects of phenytoin on experimental colonic anastomoses.

Background And Aims: Anastomotic dehiscence following colorectal surgery is a significant cause of morbidity and mortality. Phenytoin has wound-healing promoting and collagenase inhibitory effects. This study assessed these effects on healing of experimental colonic anastomoses in a rat model.

An adenomatoid odontogenic tumor with unusual clinical features.

Adenomatoid odontogenic tumors are uncommon odontogenic lesions characterized by duct-like structures that form from the epithelial component of the lesion. Most of these masses develop in the second or third decade of life, and there is a strong female bias in occurrence. Typically, these lesions arise in the lateral incisor/canine region of the maxilla, where they produce a swelling.

The value of routine antibiotic prophylaxis in mandibular third molar surgery: acute-phase protein levels as indicators of infection.

Postoperative infections in the oral region are usually caused by anaerobic bacteria. While some authors claim that routine antibiotic prophylaxis is necessary after third molar surgery, others do not recommend this practice. The major subject of controversy is what constitutes postoperative infection.

Cleidocranial dysplasia. Case report.

A 29-year-old Caucasian woman who presented with short stature and multiple unerupted supernumerary teeth is described. Radiological investigations of her cranial and skeletal abnormalities revealed cleidocranial dysplasia. Because of the advanced age of the patient and contraindication for orthodontic treatment, only surgical and prosthetic treatment were performed.
