OBJECTIVE To determine whether cervical mucus aspiration before intrauterine insemination (IUI) has any effect on clinical pregnancy rates. METHOD The outcomes of 186 IUI cycles in 95 consecutive patients in whom mucus was aspired prior to IUI were compared retrospectively with those of 1057 IUI cycles in 505 women. RESULTS The pregnancy rate was 15.1% (28 pregnancies for 186 cycles) in the...

Background: Hematometra is an uncommon disorder that can be caused by congenital or acquired structural obstruction of the cervical canal. Acquired cervical stenosis can develop due to surgical procedures performed on the uterus or cervix. Common symptoms associated with this disorder include amenorrhea or dysmenorrhea in premenopausal women, pelvic pain or pressure, urinary frequency and reten...

BACKGROUND The sagittal diameter of the cervical spinal canal is of clinical importance in traumatic, degenerative, and inflammatory conditions. A small canal diameter has been associated with an increased risk of injury; however, there is a lack of reliable normative data on spinal canal diameters in different age groups in the United States population. The purpose of this study was to use dir...

The height, width, and cross-sectional area of the vertebral canal and spinal cord along with the area ratio of spinal cord to vertebral canal in the cervical vertebra were evaluated in images obtained using computed tomography (CT). Measurements were taken at the cranial, middle, and caudal point of each cervical vertebra in eight clinically normal small breed dogs (two Shih Tzu, two Miniature...

The purpose of this study was to investigate the influence of cervical preflaring on determination of the initial apical file in maxillary lateral incisors. Forty human lateral incisors with complete root formation were used. After standard access cavities, a size 06 K-file was inserted into each canal until the apical foramen was reached. The WL (WL) was set 1 mm short of the apical foramen. F...

A 21-year-old woman presented with cervical myelopathy due to nontraumatic cervical disc herniation associated with cervical canal stenosis. The patient underwent removal of the herniated disc and anterior fusion with an autogenous iliac crest bone graft. After surgery, the patient showed satisfactory improvement. Cases of cervical disc herniation in our center and reported cases without cervic...

The hypothesis that somatotype and cervical spine developmental canal stenosis may be associated has been investigated by anthropometry and measurement of lateral projection cervical spine radiographs. A significant association of canal size with somatotype has been found such that those with developmentally narrow canals are more likely to have relatively shorter long-bones, particularly in th...

Traumatic spinal cord injury is one of the important causes of disability.in some of vertebral fractures,spinal canal is deformed and compromised.the relationship between the shape of the cervical canal and spinal cord hnjury has been proved but such a correlation for thoraculombar spine 50 patients with compromised canal(cases) and 50 oatients with intact canal were evaluated in the light of s...

Diffuse idiopathic skeletal hyperostosis previously has been reported to cause a number of extraspinal manifestations including dysphagia, respiratory distress, dysphonia and cervical myelopathy. We report a case of cervical DISH so extensive as to interfere with the swallowing mechanism and lead to aspiration. Patients with DISH who have mechanical compression of the posterior pharynx may be a...

A technique of combined expanding laminoplasty using longitudinal interspinous iliac bone graft with posterior lateral mass plate is described for the treatment of cervical canal stenosis associated with spinal instability. A 52-year-old male and a 76-year-old female presented with cervical myelopathy. Imaging studies demonstrated spondylotic cervical canal stenosis associated with spinal insta...
