The present report describes the case of a patient who underwent maxillary sinusitis right after dental implant installation with sinus lifting. Computed tomography scan revealed a dental implant (#16) was protruded inside the right maxillary sinus and confirmed the obstruction of ostium. A symptom remission was gained with the dual approaches combined by functional endoscopic sinus surgery and...

Dendritic spinules of rat nigral neurons were visualized at electron microscopic level by acetylcholinesterase immunocytochemistry and serial sections of the nigral dendrites. The spinules (at least 150 nm in length and 10-20 nm in width) which protruded from the spine heads are found in extracellular space in the neuropil and particularly between nerve terminals of the presynaptic neurons and ...

Inflammatory myofibroblastic tumor is currently considered to be a low-grade neoplasm, and it rarely involves the heart. We reported a rare case of a 59-year-old female who received cardiac surgery for complete resection of inflammatory myofibroblastic tumor in the left atrium. Five months after surgery, the patient presented with acute cardiogenic pulmonary edema and subsequent sudden death du...

Unilateral condylar injury is known to be a frequent cause of mandibular asymmetry. Whether this is due to the trauma itself or to the disturbed function that follows the injury is a very important question with ramifications for clinical complications related to facial asymmetries. The aim of this study was to test the hypothesis that mandibular function in a protruded position can compensate ...

a four- year-old moghanian breed ewe was admitted to the large animal veterinary clinic, university of tabriz due to dystocia. during obstetrical examination, it was revealed that the cervix has been closed firmly and vagina protruded about 5 cm through the vulva (vaginal prolaps). based on clinical findings and for saving the dam and lamb(s), the cesarean section was done. a normal alive femal...

A 15-year-old female patient with progressive pulsatile exophthalmos caused by intraorbital encephalocele was evaluated with computed tomography (CT) and magnetic resonance imaging (MRI) in our clinic. She had no history of trauma or reconstructive surgery. When she was a little girl, she had undergone surgery for congenital glaucoma on the right eye. On the three-dimensional image of CT, a hyp...

In this work, the origin of the release phenomena occuring in resin-based dental restorative materials is demonstrated using confocal fluorescence microscopy and tapping mode atomic force microscopy techniques. The surface structure (microcavities, protruded filler particles, grain boundaries, and cracks) produced by water environment on the surface of composite resins and resin-modified glass-...

Acanthosis nigricans is characterized by the triad of papillomatosis, keratin hyperplasia and pigmentation in the skin. It develops in the nape of the neck, axilla and external genitalia in many cases. It was reported, however, that papilloma and hyperplastic epithelial lesions were observed also in the lip, oral cavity, esophagus and anus in some cases (Ueno, 1962). A patient with advanced gas...

We describe two cases in which balloons were used to aid in the occlusion of intracranial aneurysms with Guglielmi detachable coils. In both patients, initial attempts to place coils within the aneurysmal sac failed, as the loops of the coil repeatedly protruded through a wide aneurysmal neck into the parent vessel. Temporary balloons placed across the neck of these small, wide-necked aneurysms...
