The actual prevalence of cancer-related human papillomavirus (HPV) genotypes in cervical acetowhite lesions has not been established. In this work, the presence of oncogenic types of HPV in cervical acetowhite tissue was evaluated by molecular means. The presence of HPV DNA was determined in a group of women with and without cervical acetowhite lesions by a polymerase chain reaction (PCR) using the MY09/MY11 primers. The presence of 13 oncogenic HPV types was evaluated using the Hybrid Capture II test, and the prevalence of HPV type 16 (HPV16) was studied using an HPV16-specific PCR. HPV DNA was detected in 85.9% patients with acetowhite lesions; oncogenic HPV types were found in 83.7% of them; HPV16 was identified in 51.1% of the cases. HPV DNA was detected in 87.3% of the patients without acetowhite changes. Interestingly only 16.8% were infected by oncogenic genotypes and 2.5% were positive for the presence of HPV16. In conclusion, subclinical infection by oncogenic HPV genotypes is associated with the presence of acetowhite cervical tissue (p < 0.0005). Therefore, women showing acetowhite lesions might be at risk of developing cervical cancer. 相似文献

The effect of a central fusion lock on forced vergence fixation disparity curve parameters, that is, magnitudes of fixation disparity and associated phoria, curve type and the central slope of the curve, was studied in 84 subjects because of ambiguity in the previous studies. It was found that the magnitudes of exo fixation disparity and exo associated phoria decreased significantly when they were measured with the central fusion lock. The central lock had no noticeable effect on the type of the curve, although, the central slope of the curve was flatter in the presence of the central lock. 相似文献

Transient synovitis of the hip in children: role of US 总被引:7,自引:0,他引:7

Transient synovitis of the hip remains a common diagnostic problem for the clinician. The physical signs are not pathognomonic of the condition, and the classic technical examinations are of little help. Therefore, the authors retrospectively studied the value of hip arthrosonography in 46 children with clinical symptoms suggesting pathologic hip conditions. In 20 of the 21 patients with a final diagnosis of transient synovitis, articular effusion was detected on ultrasound (US). Conventional radiography showed an increased medial joint space in only eight of these patients. Increased echogenicity of the articular fluid was found in both transient synovitis and septic arthritis. The high sensitivity of US in detecting intraarticular fluid was demonstrated by cadaver studies. 相似文献

A case-control study was performed to determine whether an association exists between cancellation of ambulatory cataract
surgery in adults, preoperative test results, and systemic diseases present at clinical examination. Among 500 adults who
were to undergo ambulatory cataract surgery, cancellation of surgery due to medical events was not associated with results
of preoperative testing (hemoglobin, serum glucose, and electrocardiogram). The rate of surgery cancellation was higher only
in patients having a history of arterial hypertension.

Diagnosis of the thoracic outlet syndrome is often difficult, particularly in patients without osseous abnormalities on plain radiographs. The radiographic and computed tomographic (CT) findings were reviewed from 27 patients with thoracic outlet syndrome and 21 normal subjects. The plain radiographs and CT scans were assessed by two independent observers without awareness of the clinical history. Fifteen patients with thoracic outlet syndrome had osseous abnormalities (anomalous cervical ribs; abnormally long, drooping C-7 transverse processes) identifiable on plain radiographs. CT did not provide further diagnostic information in the patients with abnormal radiographs. Eight of 12 patients (66%) with normal plain radiographs had abnormal findings on CT scans, consisting of impingement of the C-7 transverse process on the scalene triangle or anteromedial aspect of the middle scalene muscle. Only two of 21 control patients (9.5%) displayed this CT abnormality (P less than .01). CT may be useful in patients with symptoms suggestive of thoracic outlet syndrome and no osseous abnormalities on plain radiographs. 相似文献
