An interinstitutional review of the value of FNAB in pediatric oncology in resource-limited countries.

Fine-needle aspiration biopsy (FNAB) has been widely accepted as a reliable diagnostic modality in the general pediatric population, but its role in pediatric oncology still remains elusive. With new treatment protocols subscribing to preoperative chemotherapy, the need for a quick, minimally invasive, and accurate diagnostic procedure has arisen. This study assesses the feasibility of FNAB in childhood malignancies to render a specific diagnosis on which treatment can be initiated.

Cytologically detected chlamydial changes and progression of cervical intraepithelial neoplasias. A retrospective case-control study.

Fifty-four patients with Chlamydia-associated changes on the cervical smears, in whom adequate follow-up had been obtained over a two-year period, were investigated. The progression to biopsy-proven cervical intraepithelial neoplasia (CIN) III in this group was 42.6%, significantly higher than the 15.
