Interleukin (IL)-6, interleukin (IL)-8 levels and cellular composition of the vitreous humor in proliferative diabetic retinopathy, proliferative vitreoretinopathy, and traumatic proliferative vitreoretinopathy.

Purpose: To investigate the interleukin (IL)-6 levels, IL-8 levels, and cellular composition of the vitreous humor in patients with proliferative diabetic retinopathy (PDR), proliferative vitreoretinopathy (PVR), and traumatic PVR.

Methods: Vitreous samples from 14 patients with PDR, 10 patients with PVR, and 10 patients with traumatic PVR were analyzed. Fifteen cadaver eyes were used as controls.

Pheochromocytoma of the urinary bladder.

The case of a 65-year-old male with pheochromocytoma arising in the urinary bladder is presented. Clinical evaluation included ultrasonography, intravenous pyelography and computerized tomography (CT) scan. Transurethral resection of an exophytic tumor 1 cm in diameter was performed.

Prostatic intraepithelial neoplasia in prostate specimens: frequency, significance and relationship to the sampling of the specimen (a retrospective study of 121 cases).

Objectives: To determine the frequency of PIN (prostatic intraepithelial neoplasia) in prostate specimens and the relationship of PIN with PCA (prostatic carcinoma) and amount of sampling of the specimen.

Materials And Methods: All the haematoxylin-eosin stained slides of 121 cases diagnosed between 1990 and 1995 were re-examined retrospectively. The amount of sampling of prostate specimens was also re-examined.

Brush technique in ocular surface cytology.

New techniques are being searched for the evaluation of cellular morphology and population of ocular surface. Impression cytology is one of the most preferred techniques in ocular surface sampling in dry eye, keratitis, and conjunctivitis. We evaluated and compared the efficacy of impression and brush cytology in 63 patients.

Human papillomavirus detection in cervical smears and cervical tissue excised by the Loop Electrosurgical Excision Procedure (LEEP). Diagnostic value of cytology, colposcopy and histology.

A study was performed on 176 patients with benign cervical lesions. Human papillomavirus (HPV) structural antigens which were stained with the immunoperoxidase staining were sought for in cervical smears and in cervical tissues excised by the loop electrosurgical excision procedure (LEEP). HPV infection was found in 16.
