High risk of human papillomavirus infection and cervical squamous intraepithelial lesions among women with symptomatic human immunodeficiency virus infection.

We investigated the relationship of human papillomavirus (by cervicovaginal lavage and Southern blot), human immunodeficiency virus, and squamous intraepithelial lesions in 96 high-risk women in the Bronx, New York. Antibodies for human immunodeficiency virus were detected in 51 (53%) women. Of the 33 women with symptomatic human immunodeficiency virus infection, 23 (70%) had human papillomavirus infection compared with 4 of 18 (22%) asymptomatic women who were human immunodeficiency virus seropositive and 10 of 45 (22%) uninfected women (p less than 0.0001). The rate of squamous intraepithelial lesions was 52% (14 of 27) for women with both viruses detected, 18% (6 of 34) for women with either virus detected, and 9% (3 of 35) for uninfected women. Among symptomatic human immunodeficiency virus-infected women, a strong association between human papillomavirus infection and squamous intraepithelial lesions was demonstrated (odds ratio, 12; 95% confidence interval, 1.3 to 108). Risk was highest for younger women from ethnic or racial minority groups. Advanced human immunodeficiency virus-related disease, with its associated immunosuppression, seems to exacerbate human papillomavirus-mediated cervical cytologic abnormalities. Public health measures are needed to provide Papanicolaou smear screening and appropriate clinical follow-up and treatment for women at high risk for human immunodeficiency virus infection.

Cervical cytologic abnormalities and papillomavirus in women infected with human immunodeficiency virus.

We investigated the relationship of human papillomavirus (HPV) infection of the female genital tract, cervical cytology, and human immunodeficiency virus (HIV) infection in 67 women. Forty-eight women had a history of intravenous drug use, 18 were heterosexual partners of HIV-infected intravenous drug users, and one was a transfusion recipient. Patients received a Pap smear, cervicovaginal lavage for HPV determination by Southern blot, HIV serum antibody by enzyme immunoassay with Western blot confirmation, and thorough screening for other sexually transmitted diseases. Seventeen of the 35 (49%) women seropositive for HIV had HPV infection, compared with 8 of 32 (25%) seronegative women (p less than 0.05). Fourteen of 35 (40%) HIV-positive women had squamous intraepithelial lesions (SIL) on cervical cytology, compared with three of 32 (9%) HIV-negative women (p less than 0.01). Of 22 women with symptomatic HIV infection, 11 (50%) had SIL on cytology; 10 of these 11 were HPV-positive. Among 13 asymptomatic HIV-positive women, only three (23%) had such cytological lesions. Our findings strongly suggest that HIV-induced immunosuppression exacerbates HPV-mediated cervical cytologic abnormalities.

Cervical and vaginal squamous cell abnormalities in women infected with human immunodeficiency virus.

We sought to determine whether women infected with human immunodeficiency virus (HIV) had cervicovaginal cellular changes suggesting lower genital tract neoplasia or human papillomavirus (HPV) infection at a rate different from that in women without HIV infection. In a blinded fashion, cytological preparations of cervicovaginal smears from women infected with the HIV were analyzed and compared to preparations from women at high risk for but not infected with HIV. Eleven of 35 (31%) HIV-infected subjects had evidence of squamous abnormalities compared with 1 of 23 (4%) non-HIV-infected women (p = 0.019). Nine of 35 (26%) HIV-infected women had cytohistological evidence of human papillomavirus (HPV) infection compared to 1 of 23 (4%) non-HIV-infected women (p = 0.072). We conclude that HIV-infected women have a high prevalence of cervical and vaginal cytological abnormalities and evidence of genital HPV infection. Further study is necessary to determine whether there is an increased risk for cervicovaginal neoplastic disorders in women infected with HIV.

Computed tomography guidance for skeletal biopsy.

Computed tomographic (CT) guided biopsy and abscess drainage of multiple organ systems have been well described. Reports of spinal and skeletal applications have been less common. This study describes the use of CT guidance in the biopsy of various skeletal lesions in 46 patients. Forty-one patients had skinny needle aspirations (18 or 22 gauge) and 23 patients had trephine core biopsies. Sites of the lesions included: thoracic spine-15 patients, lumbosacral spine-17 patients, bony pelvis-6 patients, rib-2 patients, and long bones-6 patients. Fast scanners capable of rapid image reconstruction have overcome many constraints. With CT guidance, the physician who performs the procedure receives virtually no ionizing radiation. The exact location of the needle tip is accurately visualized in relation to the lesion being biopsied and to the vital organs.

Thin-needle aspiration biopsy of the prostate.

The authors summarize the current status of thin-needle aspiration biopsy of the prostate and evaluate the accomplishments and limitations of this method of diagnosis. Historical developments, indications, technique, contraindications, complications, cytology of aspirates, diagnostic efficacy of aspirates, and grading of prostatic carcinomas are discussed.

The initial evaluation of masses of the neck by needle aspiration biopsy.

Needle aspiration biopsy for cytologic study is a simple, safe and accurate procedure for evaluation of cervical masses. It is a valuable initial step for evaluation of undiagnosed neck masses and is most efficacious for follow-up evaluation of patients previously treated for cancer. The procedure does not interfere with subsequent treatment. Information obtained from aspiration cytologic findings is used to plan subsequent evaluation and treatment in the simplest and most cost effective manner.

Detection of endometrial carcinoma and hyperplasia in asymptomatic women.

Occult endometrial carcinoma is a detectable disease using commercially available sampling devices and cytohistologic techniques. A cohort of 2586 asymptomatic women (98% past the age of 45, 78% caucasian) was screened. Of these women, 1567 were screened twice, and 187 were screened three times. The prevalence and incidence rates of endometrial carcinoma, as defined in the present study, including four missed cases, were 6.96 per 1000 and 1.71 per 1000 women years, respectively. The prevalence rate was 7.38 per 1000 for caucasian women and 5.40 per 1000 for women of other races. An epidemiologic evaluation suggested that the onset of menopause past the age of 49 was the only statistically significant risk factor, whereas race, parity, estrogen intake, and obesity, as calculated by the Quetelet index, were not statistically significant. The present study strongly suggests that in asymptomatic women past the age of 50, endometrial hyperplasia does not necessarily precede or accompany the development of endometrial carcinoma. Two distinct mechanisms may be responsible for the onset of endometrial cancer: endometrial hyperplasia occurring in the symptomatic and younger woman; and endometrial adenocarcinoma occurring ab initio in the older patient.

Malignant mesothelioma of the tunica vaginalis testis: report of first case with preoperative diagnosis.

The cytologic, histologic and ultrastructural features of a malignant carcinomatous mesothelioma of the tunica vaginalis testis in a 30-year old patient are described. This is the first such case with preoperative diagnosis by cytologic examination of hydrocele fluid and the second with documented history of exposure to asbestos. The identity of the tumor was confirmed by a positive immunoperoxidase reaction directed against mesothelial cells. A review of the previously described ten cases is presented.

Endometrial carcinoma and its precursors: detection and screening.

This article summarizes the current status of an endometrial cancer detection program in asymptomatic women based on personal experience with 2007 examinees seen during 1979 and 1980. This ongoing feasibility study has shown that occult endometrial carcinoma occurs in approximately 5 of 1000 women age 45 and above and that the disease can be identified by the sampling techniques described in this paper. The identification of high-risk groups is emerging from this prospective study and may lead to a cost-efficient detection protocol that may prove applicable to large scale population screening. The benefits of this study in terms of lowered morbidity and mortality from endometrial carcinoma cannot be documented as yet and require several additional years of follow-up. Perhaps the principal benefit of this study is that it has provided prevalence data for endometrial carcinoma in a hitherto unscreened asymptomatic population against which all future efforts at endometrial cancer detection will have to be measured.

DNA distribution in human colon carcinomas and its relationship to clinical behavior.

Striking differences in outcome of surgically treated colon adenocarcinomas were observed in 33 patients according to the DNA distribution patterns in tumor nuclei, measured by flow cytometry. As discussed and defined in the text and confirmed by appropriate control studies, the tumors were classified into 2 groups: predominantly diploid (20 tumors) and predominantly nondiploid (13 tumors). During the follow-up period of 3-5 years, 12 of the 13 patients with "nondiploid" tumors died of disease within 4-34 months, and the 1 patient still alive after 59 months has extensive metastases. Only 6 of the 20 patients with "diploid" tumors died of disease, sometimes after a slow, protracted clinical course. There were 14 patients with no evidence of disease for periods ranging from 30 to 60 months; 1 of these patients died of other causes. Histologic grading and Dukes' staging appeared to play a relatively limited role in the outcome, although lymph node metastases and vascular invasion were more often observed in the nondiploid tumors. These observations suggest that the determination of DNA distribution in colon carcinomas may prove to be of prognostic value.
