purpose: to present a case of orbital abscess secondary to mandibular odontogenic infection. case report: a 30 year old man presented with ocular pain and exophthalmos of the left eye following a dental infection since a few days ago. a localized abscess was detected in the left orbital ct but the paranasal sinuses were clear. involvement of the left third mandibular molar was evident on facial...

The effect of intracarotid injections of ouabain (25.0 ng) or acetylstrophanthidin (1.56 tig) on feline carotid sinus baroreceptors was evaluated using an isolated perfused carotid sinus preparation. The effects of the drugs on baroreceptor activity were determined by monitoring carotid sinus nerve activity and systemic arterial blood pressure. Administration of either drug to the isolated caro...

Introduction: Maxillary sinus lift combined with implant placement without grafting allows bone formation in the sinus. However, bone volume in severely atrophic maxilla is often insufficient to ensure initial stability of implants. The purpose of this study was to evaluate the outcome of maxillary sinus augmentation by graft-free two-stage sinus lift using titanium bone fixation device and imp...

In 35 patients aged 18 to 69 years (mean 48) with clinical, electrocardiographic, or electrophysiological evidence of normal sinus node function, the effect of intravenous propranolol (0.1 mg/kg) was assessed on 3 indices of sinus node function. The drug significantly prolonged sinus node cycle length (12%), slightly prolonged the corrected sinus node recovery time (15%), and slightly but insig...

Sinus-node function was characterized in 13 patients during cardiac catheterization by the introduction of progressively premature atrial depolarizations. Curves relating the extent of sinus-node depression following these premature depolarizations and their degree of prematurity were constructed. The maximum extent of sinus-node depression following premature depolarizations and A-V-nodal and ...

introduction calcifying odontogenic cyst (coc) is an uncommon odontogenic lesion, classified in two variants: the cystic variant and neoplastic (solid) variant. case presentation this case report presents multiple coc, which involved the maxillary bone and sinus in a 30-year-old man. several of these lesions were cystic, while the others were neoplastic in type, and the lesions were removed sur...

background & importance: the aim of this study was to demonstrate the result of transsphenoid microsurgery for cushing disease in our center and comparing the results in details with other articles, to achieve the best decision for patients management in future. case presentation: between 1991 to 2015, 50 patients suffering from cushing disease were operated. before operation, endocrine tests a...

in this paper, we describe a case of an aneurysmal circumflex artery connected to the coronary sinus through a fistula in a 40-year-old man with a two-year history of palpitation and chest pain. we discussed surgical management for patients with coronary artery fistula (caf), particularly for asymptomatic patients with a small left-to-right shunt .
