Human papillomavirus--a study of male sexual partners

Male sexual partners of a cohort of women with genital-tract abnormalities which were associated with human papillomavirus infection were examined for evidence of infection with human papillomavirus. Of the 214 male partners who were examined, 93.5% had visible genital lesions. Of the 196 lesions that were biopsied, 72.5% showed histological evidence of infection with human papillomavirus, and only 20.4% of subjects with histological evidence of human papillomavirus were aware of a lesion. An unexpectedly high proportion (6.1%) of lesions on which a biopsy was performed, particularly those with flat, red, indurated morphology, also showed histological evidence of penile intraepithelial neoplasia. This was not significantly more common among the partners of the women with cervical intraepithelial neoplasia than it was among the partners of the women with other evidence of genital human papillomavirus infection. Penile intraepithelial neoplasia was significantly (P less than 0.001) more common among subjects with no history of non-genital warts. We conclude that the male partners of women with human papillomavirus-associated lesions are very likely to be infected with human papillomavirus, and thus may act as a significant reservoir for the reinfection of their female partners. As the awareness of human papillomavirus-associated lesions was low among the male partners, colposcopic examination and treatment of their male partners, and/or barrier contraception, may be a necessary part of the management of women who are undergoing treatment for human papillomavirus-associated genital disease.     

Hysterectomy Revisited

This paper summarizes the results obtained in 279 vaginal hysterectomies performed in the 5 years 1985-1989 in the public and private practices of a single gynaecologist. It is suggested that it is feasible and safe to perform a hysterectomy vaginally in preference to the abdominal route in the majority of women, even in the absence of uterine descent. It is essential that registrars in training continue to be thoroughly versed in the techniques of vaginal surgery if such techniques are not to be forgotten.     

Low-artifact intravascular devices: MR imaging evaluation

Flow-phantom magnetic resonance (MR) imaging, with use of both spin-echo (SE) and gradient-echo (GRE) techniques at 1.5 T, was performed on the percutaneous Greenfield (beta-III titanium alloy [TMA wire]), Amplatz (MP32-N alloy), and Simon nitinol filters and TMA wire facsimiles of the bird's nest, Gunther, new retrievable, and Amplatz vena caval filters. SE imaging allowed detection of thrombi as small as 5 X 5 mm trapped within the percutaneous Greenfield, Simon nitinol, and TMA-wire facsimile filters; with the MP32-N Amplatz filter, a larger volume of thrombus (10 X 20-mm clots) was necessary for clot detection. GRE imaging allowed detection of intraluminal tilting of the percutaneous Greenfield and facsimile Amplatz (TMA-wire) filters. GRE imaging was useful for demonstrating postfilter turbulence due to clots, which was greatest for the Amplatz filter. Imaging of facsimile vascular devices made of tantalum or TMA wire did not cause the severe "black-hole" MR artifacts typical of the stainless-steel devices. SE and GRE imaging were very useful for determining caval patency in two patients with previously placed Mobin-Uddin filters. Noninvasive MR evaluation of blood vessels in the presence of a variety of low-artifact intravascular devices appears feasible.     

Left ventricular aneurysm formation: an iatrogenic cause for the third mogul

Two cases of left ventricular pseudoaneurysm formation developing post-operatively after mitral valve replacement are reported. The chest radiographs showed an abnormal protuberance on the left heart border at the site of the "third mogul". The definitive diagnosis of this protuberance, resulting from the development of a left ventricular aneurysm, was made on angiography in each case. This site is unusual for left ventricular aneurysm formation, with the exception of the annular subvalvular aneurysm described in the negro population. Relevant aetiological factors in the development of these post-operative left ventricular pseudoaneurysms are considered. Since pseudoaneurysms are more prone to rupture than true aneurysms, it is concluded that early diagnosis of development of these left ventricular pseudoaneurysms should be made.
