Nasal bilevel positive airway pressure therapy in children with a sleep-related breathing disorder and attention-deficit hyperactivity disorder: effects on electrophysiological measures of brain function.

OBJECTIVE: To examine the effect of nasal bilevel positive airway pressure (BiPAP) treatment for concurrent sleep-related breathing disorders (SRBDs) and attention-deficit hyperactivity disorder (ADHD) on electrophysiological measures of spontaneous brain activity and auditory stimulus processing. METHODS: Nineteen children diagnosed with both SRBD and ADHD participated. Electroencephalogram (EEG) activity was recorded during a resting period and an auditory oddball task before beginning BiPAP treatment, after 6 months on treatment, and after a subsequent 1 week non-treatment period. Treatment effects on EEG and event-related potentials (ERPs) to target stimuli were examined via topographic analysis. RESULTS: Thirteen of the initial 19 children completed 6 months of BiPAP therapy, with six lost mainly due to compliance problems. Children on BiPAP therapy showed a significant decrease in slow-wave (delta and theta) and an increase in fast wave (beta) EEG activity. The P3 component of the ERP showed treatment effects in amplitude and latency. CONCLUSIONS: The electrophysiological data suggest that SRBDs may contribute to ADHD symptomatology. Treatment of SRBD with BiPAP therapy in children with concurrent ADHD can lead to significant changes, in the direction of normalization, of the typical electrophysiological features of ADHD.

Odontogenic infections: Part one. Anatomy and radiology.

Odontogenic infections are frequently encountered by the dentist. The signs and symptoms of these common dental emergencies are outlined in this two-part article. A thorough knowledge of the fascial planes and anatomical routes of infection spread is a critical prerequisite to understanding the clinical manifestations, potential complications, and appropriate management of these infections.

Odontogenic infections: Part two. Microbiology, antibiotics and management.

This article deals with the microbiological aspects of infections, the principles and role of antibiotic use and the general management of the patient suffering from an odontogenic infection. Clinical aspects of the most common presentations will be addressed to understand the organized management of these challenging patients. (Part one appeared in Oral Health, May, 1995).

Third molar surgery: current concepts and controversies. Part 1.

The removal of impacted third molar teeth ranks as the commonest procedure in the practise of oral and maxillofacial surgery. It is the purpose of this review article to present the major controversies and correct some of the misconceptions associated with third molar surgery. This paper deals primarily with the discussion of the indications for the removal while part II describes the influence of a variety of factors upon the outcome of third molar surgery.

Third molar surgery: current concepts and controversies. Part 2.

The outcome of third molar surgery is influenced by a variety of factors including among others, mucoperiosteal flap design and flap closure and the use of antibiotics and corticosteroids. This article discusses the special significance of modifying factors upon the incidence of perioperative complications associated with third molar surgery.

Fractures of the zygomatic complex: a case report and review.

Traumatic injuries to the midface are not nearly as common in Canada as they are in the United States, but practitioners must still be prepared for the evaluation and treatment of patients presenting with midface fractures. This case report demonstrates the experience one individual who presented with the clinical signs and symptoms of midfacial trauma. Cases of this nature can be confidently managed by an oral and maxillofacial surgeon. A review provides knowledge regarding anatomic features, classification schemes and the diagnostic and therapeutic decisions encountered with the treatment of zygomatic complex fractures. The forward projection of the zygoma causes it to be frequently injured secondarily to blunt trauma of the midface, at the expense of protecting the orbit.
