Treatment of penile intraepithelial neoplasia (PIN) with interferon alpha-2a, CO2 laser (vaporization) and 5-fluorouracil 5% (5-FU)

This study was undertaken to assess the effectiveness of CO2 laser (vaporization), 5-FU topical application and Interferon (IFN alpha-2a) parenterally in the therapy of penile intraepithelial neoplasia (PIN). From March 1986 to September 1991, 1,372 men, sexual partners of women with condylomata accuminata or flat or cervical intraepithelial neoplasia (CIN), were submitted to peoscopy, of 1,019 men who presented with various lesions caused by human papillomavirus (HPV)-confirmed histologically-208 were treated for PIN. The best treatment modalities irrespective of grade of lesion were found to be the combination of 5-FU plus CO2 laser vaporisation plus IFN alpha-2a (high dose) (96.15%), the combination of 5-FU plus CO2 laser vaporization (87.09%) and the combination of CO2 laser vaporization plus IFN alpha-2a (high dose) (80%). It is concluded that IFN alpha-2a (low dose) can be used as first line treatment in combination with 5-FU in patients with PIN II and as an adjuvant treatment (high dose) in patients with recurrent PIN I and PIN III.

Treatment of flat or accuminata condylomata of the female genital tract with interferon alpha-2 alpha

This study was undertaken to assess the effectiveness of Interferon administered parenterally in the treatment of flat or accuminata condylomata of the female genital tract. One hundred and forty-three women with condylomata were treated with CO2 laser vaporization, 5-FU topical application and interferon alpha-2 alpha (IFN alpha-2 alpha) parenterally. The cure rates in the various treatment groups were analysed by the chi-square test. The cure rates of the treatments used in the patients with condylomata accuminata were similar (p>0.1). The best cure rate for flat condylomata was achieved with the combination of CO2 laser vaporization plus 5-FU plus IFN alpha-2 alpha (high dose) (p<0.01). In conclusion, Interferon can be used as adjuvant treatment in patients with recalcitrant condylomata accuminata and as first line treatment in combination with 5-FU and CO2 laser vaporization in patients with flat condylomata.

Peoscopic diagnosis of flat condyloma and penile intraepithelial neoplasia. IV. Urethral reservoir

The aim of the present study was to test the method of urethral cytologic sampling and to assess its results in the cytologic detection of human papillomavirus infection in the male partners of infected women. Cytologic evidence of abnormal epithelium was found in a total of 50 out of 167 cases (29.94%). It is interesting to note that 9 (5.38%) patients with cytological evidence of flat condylomas of the urethra did not have any other lesion. On the basis of the present study, we conclude that cytobrush urethral cytology should be routinely associated with peoscopy in studying the male partners of women affected by human papillomavirus infection, in an effort to diminish the reservoir of a virus strongly associated with cervical and penile neoplasia.

Treatment of urethral condylomata acuminata or flat condylomata with interferon-alpha 2a

The effectiveness of intraurethral 5-fluorouracil and systemic administration of interferon-alpha 2a in the therapy of condylomata acuminata or flat condylomata of the urethra is assessed. From March 1986 to September 1991, 1,372 male sexual partners of women with condylomata acuminata, flat condylomata or cervical intraepithelial neoplasia underwent urethroscopy and brush cytological examination of the urethra. Of these men 305 (22.23%) had intraepithelial human papillomavirus (confirmed cytologically) and 284 were treated. The best treatment modalities, regardless of the type of lesion, were the combinations of 5-fluorouracil plus high (95.34%) and low (70.58%) dose interferon-alpha 2a. Interferon-alpha 2a can be used as first line treatment with 5-fluorouracil cream in patients with intraurethral condylomata acuminata or flat condylomata.

Comments by the 'Information by Phone' Department of the Sex Medical Institute on the telephone calls related to sexuality and contraception

The present study which was carried out by the Sex Medical Institute has been based on 5252 telephone calls related to sexual or contraception matters, which were received in the period February 1989 to July 1991. Of the calls, 58.8% came from men and 41.2% from women. The main topics of the questions concerned masturbation (frequency, guilts), anatomy of the genital system (anxiety and concern on the length of the penis, virility, femininity), the first sexual experience (fear, anxiety of failure).
