The purpose of this study was evaluation of anesthesia success rate of 3% mepivacaine compared with 2% lidocaine 1/80000 epinephrine in inferior alveolar nerve block in thirty voluntary students. All of the subjects were healthy and had not received any medicament. They pariticipated for two appointments and each time randomly received an inferior alveolar nerve injection with one of the anesth...

conclusions the abovementioned ivc ultrasonographic criteria for hemodynamic congestion appear clearly inconsistent. alternatively, a sequential or simultaneous combination of clinical scores of congestion, ivc ultrasonographic indices, and circulating levels of natriuretic peptides could be warranted. background among the indices able to replace invasive central venous pressure (cvp) measureme...

background in spite of common usage of the inferior alveolar nerve block (ianb), this method has some well-defined restrictions. objectives the purpose of the present study was to compare these two techniques for the surgical removal of impacted lower third molars. patients and methods a total of 44 similarly impacted lower third molars (22 patients with two similar teeth) were selected. in eac...

conclusions noninvasive assessment of the patient hydration condition using the ultrasound is a simple and practicable measure in emergency. with regard to the considerations, it is possible to estimate cvp via diameter measurement and cross-section of the central veins. results twenty patients with the mean age of 60.3 were studied. the main reason for cardiac catheterization was shock. there ...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

we reported ct of a case of giant organized hematoma originating from the inferior turbinate without any paranasal sinuses involvement, with an emphasis on different patterns of enhancement of the tumor on enhanced ct scans. this case was exceptional because of unusual location and difficulties in diagnosis. moreover, organized hematoma of nasal cavity should be considered in the differential d...

Hydatid cyst is a helminth infection. The rupture of a hepatic hydatid cyst in inferior vena cava is a rare and lethal complication. Pulmonary embolism is the commonest manifestation. The diagnosis of hydatid cyst is made by histopathological or serological examination, and imaging may suggest the probability of hydatid cyst. Surgical treatment should be performed with caution and always under ...

introduction: nasal inferior turbinate hypertrophy is one of the most common causes of nasal obstruction. many different surgical methods are currently available. the aim of this study was to review the efficacy and results of radiofrequency turbinatoplasty as a new method in the treatment of the large inferior nasal turbinate. materials and methods: this prospective study was conducted on 50 p...
