PCR study of a series of ASCUS cases HPV-positive by HCII.

Most guidelines currently recommend the testing of human papillomavirus (HPV) in ASCUS cases. The most used method for this purpose is Hybrid Capture II (HCII), but PCR techniques with GP5+/6+ primers can be also applied. Furthermore, the HCII high-risk probe test for detection of HPV shows cross-reactivity with low-risk HPV.

HPV determination in the control after LEEP due to CIN II-III: prospective study and predictive model.

To evaluate the usefulness of the endocervical cytology immediately after loop electrosurgical excision procedure (LEEP) and viral human papilloma virus (HPV) determination as predictive factors of persistence/recurrence (P/R) of squamous intraepithelial lesion (SIL) in the remaining cervix of patients treated with LEEP due to cervical intraepithelial neoplasia (CIN) II or III. We retrospectively selected 105 samples from 100 patients with histologic diagnosis of CIN II-III with cytology immediately after LEEP with a first control post-LEEP between 2 and 6 months after treatment that included HPV determination, a minimal follow-up period of 12 months and maximum of 24 months, and at least 2 colpocytologic controls post-LEEP. In 71 of the 105 patients (67.

The Ki-67 labeling index is not a useful predictor for the follow-up of cervical intraepithelial neoplasia 1.

Objective: Our aim was to determine whether the Ki-67 immunostaining pattern, present on diagnosis of cervical intraepithelial neoplasia (CIN), predicts the change from low-grade to high-grade CIN over a 2-year period after diagnosis.

Materials And Methods: Of 59 cervical biopsy samples from 59 patients diagnosed as having cervical CIN, 35 were diagnosed as CIN 1 and 24 were diagnosed as CIN 2 or CIN 3. The Ki-67 immunostain showed immunopositive cells in the upper two thirds of the epithelium in all specimens.

Bone metabolism and histomorphometric changes in rheumatoid arthritis.

Objective: We studied bone metabolism and histomorphometry in 66 patients with rheumatoid arthritis.

Methods: Cross-sectional study.

Results: BMD at the forearm but not at the lumbar spine was decreased.

The 18q21 region in colorectal and pancreatic cancer: independent loss of DCC and DPC4 expression.

Unlabelled: The 18q21 region is frequently altered in gastrointestinal tumors. Three candidate tumor suppressor genes have been identified in it: DCC, Smad4/DPC4 and Smad2; the mechanisms involving their inactivation have not been completely elucidated. In this study, genetic losses at 18q21 and expression of DCC and DPC4 in colorectal (n=12) and pancreatic (n=16) cell lines and in colorectal tissues (n=10) were analyzed.
