BACKGROUND AND PURPOSE The present study prospectively evaluated relationships among baseline characteristics, cerebral hemodynamics, and outcome of patients with symptomatic major cerebral artery occlusion, by quantitative measurement of cerebral blood flow using xenon-133 (133Xe) inhalation and single-photon emission computed tomography (SPECT). METHODS Regional cerebrovascular reactivity (...

Laser targeted photo-occlusion (LTO) is a novel method being developed to treat choroidal neovascular membranes (CNV) in age-related and other macular degenerations. A photosensitive agent, encapsulated in heat-sensitive liposomes, is administered intravenously. A low power laser warms the targeted tissue and releases a bolus of photosensitizer. The photosensitizer is activated after it clears ...

PURPOSE The aim of this study was to evaluate masticatory efficiency in children with normal primary occlusion and malocclusion and to correlate efficiency with body variables. METHODS Thirty children were divided into three groups: Group I with normal occlusion (n = 10), Group II with posterior crossbite (n = 10) and Group III with anterior open bite (n = 10). They chewed standardized silico...

Occlusion is commenced by contact of a tooth with an opposing tooth and is the mechanical force working against the periodontal ligament (PDL). Our recent study indicated that occlusion regulated tooth-root elongation occurs during root development in rat molars. Using a non-occlusal model established to directly examine the effects of the absence of occlusion in developing first molars of uppe...

Case report: A 37-year-old man was admitted for a right MCA transient ischaemic attack. He was smoker, obese, dyslipidaemic, with previous history of heroin addiction and cured B and C hepatitis virus infections. Brain magnetic resonance and cardiac evaluation were normal. Transcranial color-coded sonography (TCCS) showed >50% proximal right MCA stenosis and distal left MCA occlusion. Treatment...

PURPOSE Occlusal splints are commonly used to prevent tooth wear caused by bruxism. However, the effects of splints on occlusion are still unclear. Although it is rarely alluded in literature, splints can provoke severe occlusal alterations and other complications. This study was aimed to identify differences in the responses of individuals with bruxism and healthy individuals to a full-arch ma...

The effect of change of posture on the level of the intraocular pressure was studied in 22 patients who had suffered 'occlusion' of a central retinal vein, 14 patients with occlusion of a tributary of the central vein, and 23 normal subjects. The results showed a significant difference in behaviour between subjects in the control group and both groups of patients with retinal vein occlusions. I...

Background and aims. One of the most common reasons forthe inferior alveolar nerve block anesthesia failure is the variation in mandibular foramen location. The aim of this study was to assess the location of mandibular foramen in children with mandibular retrognathism in comparison to children with normal skeletal occlusion in the mixed dentition. Materials and methods. One hundred and twenty ...
