Evaluation of urinary cytology of male sexual partners of women with cervical intraepithelial neoplasia and human papilloma virus infection.

Condylomas of the genital tract can be found in 70% of patients who have cytologic evidence of human papilloma virus (HPV) infection or mild epithelial dysplasia (CIN I). Most male sexual partners of women with overt or subclinical HPV infections have no visible condylomas. Presently, there is no therapy for subclinically infected male partners. A screening test capable of detecting such HPV infections in males would be of value should effective therapy be discovered. Fifty-four men who were the current sexual partners of women with visible condylomata acuminata or with cytologic evidence of subclinical HPV infection or cervical neoplasia were asked to give a urine specimen for cytologic examination. The cytologist had no knowledge of the cytologic or histopathologic findings in the female partners. Of the 54 women, 39 (72%) had either visible genital condylomas or cytologic evidence of mild dysplasia or of HPV infection with or without mild dysplasia (CIN I). Twenty-five (63%) had histologic evidence of HPV infection with or without mild dysplasia. With one exception, urinary cytologic preparations from the study and from the control males were negative. No correlation could be found between cervical cytology and histology in the females and urinary cytologic findings in their current male partners. At the present time there is no screening test that can be utilized to detect male carriers with subclinical disease.

Plexiform (multinodular) schwannoma. A tumor simulating the plexiform neurofibroma.

We describe a rare variant of schwannoma characterized by a interconnecting multinodular growth mimicking a plexiform neurofibroma. The schwannoma recurred twice. The second recurrence was not excised and has not increased in size for 1 1/2 years. The patient is alive and well, 3 years and 4 months after the first excision with no clinical evidence of metastasis.

Cytology of nasal secretions: further diagnostic help.

Nasal cytograms, as an aid to diagnosis of pathological conditions of the nose and paranasal sinuses, have not been adopted by the majority of otolaryngologists. This situation exists because of technical problems with the preparation of a slide and the difficulty in finding someone competent and interested in its interpretation. The work of the Bryans has provided an analysis of the cytology of nasal secretions. Adopting their methods, we have been using the nasal cytogram in clinical practice and find it helpful in determining appropriate therapy for problems encountered in otolaryngological practice. In the authors' experience, profuse nasal mastocytosis is a consistent finding in cytograms from patients having varied symptoms that are associated with hypersensitivities that are not accompanied by positive objective findings. This is especially true in patients with constantly recurring headaches and those with a chronically obstructed nose. Once many mast cells are found by the cytogram, attempts are made to relieve these patients by selective dietary restrictions. These attempts are often successful. The nasal cytogram is also used to help explain periodic symptom flares in the long term allergy patient undergoing immunotherapy for inhalants, by identifying superimposed viral and bacterial infections.
