Colposcopy and computer graphics: a new method?

A new method is herein described that uses the most recent computer science techniques to obtain digitalized colposcopic images that may be useful not only as documents, but also as research tools. Because computer graphics is a recent and ever-growing discipline, our method, too, might undergo considerable improvements: some possible improvements are hypothesized in the text. The most striking features of this method are the excellent quality of images, their easy reproducibility, and the reasonable cost.

Single and multiple exposure tolerance study of cellulose sulfate gel: a Phase I safety and colposcopy study.

Vaginally applied gels offer a promising approach for preventing unwanted pregnancies and sexually transmitted infections. Cellulose sulfate (CS) is a non-cytotoxic antifertility agent that also exhibits in vitro antimicrobial activity against sexually transmitted pathogens, including HIV. This was a randomized, double-blinded, Phase I study of 2.5 mL and 5.0 mL doses of 6% CS gel. A single vaginal application of the gel followed by five consecutive daily doses was assessed for genital irritation, safety, vaginal leakage, and product acceptability compared to two controls, Conceptrol, which is a marketed contraceptive gel containing nonoxynol-9, and K-Y jelly. The results suggest that the safety of 6% CS was comparable to that of Conceptrol and K-Y jelly, and it may be associated with less genital irritation. The 2.5 mL dose of CS may be preferable according to the participants' reports of leakage. All the products had similar acceptability profiles.

Colposcopy in pregnancy: directed brush cytology compared with cervical biopsy.

OBJECTIVE: To evaluate colposcopically directed brush cytology as a substitute for directed biopsy of acetowhite lesions identified during pregnancy. METHODS: Pregnant patients eligible for the study were referred for colposcopic evaluation for either newly diagnosed abnormal cervical cytology or follow-up of a previously diagnosed squamous intraepithelial lesion (SIL). All patients with acetowhite lesions underwent colposcopically directed brush cytology followed by directed biopsy. RESULTS: Of 81 pregnant patients referred, 50 paired samples of colposcopically directed brush cytology and directed biopsies were evaluated from 49 patients. One patient was sampled in the first and third trimesters and one patient's brush cytology was unsatisfactory for interpretation because of clumping artifact, leaving 49 brush-biopsy pairs that were satisfactory for examination. One patient in the study group had an intrauterine fetal death of uncertain cause, remote from the time of biopsy. Compared with the corresponding biopsy, the directed brush caused significantly less blood loss (P < .001). For all diagnostic categories, directed cytology demonstrated a good degree of correlation with biopsy (kappa = 0.73). The brush technique correctly identified 12 of 14 cases (86%) of biopsy-proved cervical intraepithelial neoplasia II-III as high-grade SIL. If one considers "atypical squamous cells, favor human papillomavirus effect" as a true positive, brush sensitivity was 88 +/- 9% and specificity was 74 +/- 12%, with an accuracy of 80%. CONCLUSION: In the absence of lesions suspicious for carcinoma, colposcopically directed brush cytology is a safe substitute for directed biopsy in pregnant patients.

Is the SANE role within the scope of nursing practice? On "pelvics," "colposcopy," and "dispensing of medications".

Clearly communicating with other professionals and with sexual assault survivors about the boundaries and imitations of the SANE medical-forensic examination is important. Although SANEs work cooperatively in an interdisciplinary sexual assault response team model to better meet the needs of sexual assault victims, they function as independent professional nurses in their role of collecting medical forensic evidence. Properly defined to focus on assessment, identification, and documentation of trauma, the SANE role is an independent professional role but is still within the scope of basic nursing practice. The answer to our question, "Is the SANE role advanced practice nursing or is it within the scope of basic nursing practice?" is thus "The SANE role is clearly within the scope of basic nursing practice."

Colposcopy in evaluation of the adult sexual assault victim.

The purpose of this study was to determine if the colposcope improves detection of genital trauma in adult women who are victims of sexual assault compared with gross visual examination alone. A prospective, 1-month pilot study was conducted of 17 women patients who presented consecutively to Charity Hospital New Orleans during April 1994 requesting sexual assault examinations. Use of the colposcope allowed documentation of trauma in 9 of the 17 sexual assault victims (53%), compared with 1 of 17 (6%) by gross visualization alone (statistically significant: chi2 = 0.64, P = .0114). The colposcope improved detection of genital trauma in adult female sexual assault victims as compared with gross visual examination alone at a statistically significant level.

Adolescent sexual assault: documentation of acute injuries using photo-colposcopy.

OBJECTIVE: To document the frequency and types of genital injuries in adolescent women examined acutely following a sexual assault, and determine any historical correlates of injury. DESIGN: Retrospective chart review. SETTING: Sexual Assault Response Team services at a community hospital in an urban setting. PATIENTS: All female patients aged 14-19 yr who were referred by law enforcement for an acute sexual assault examination and were examined between May 1994 and May 1999. OUTCOME MEASURES: The frequency of signs of genital trauma at various anal and genital sites, as recorded by the examining clinician. RESULTS: Charts of 214 female subjects (mean age 16.3 yr) were reviewed. The most common findings were posterior fourchette tear (36%); erythema of the labia minora, hymen, cervix, or posterior fourchette (18%-32%); and swelling of the hymen (19%). Time to examination was highly correlated with the degree of injury noted (P =.000). The incidence of hymenal tears in self-described virgins was higher than in nonvirgins (19% vs. 3%, P =.008); however, the total number or severity of other injuries was not significantly higher in virgins. Victims reporting anal penetration had a higher frequency of anal injuries than those who denied such contact (14/31, 61% vs. 2/150, 1%; P =.000). CONCLUSIONS: Tears of the posterior fourchette or fossa were the most common findings (40%). Hymenal tears were uncommon, even in self-described virginal girls. Timely examination of adolescent victims is important to document injuries; however, many victims will still not have signs of bruising, abrasions, or tears.

[Colposcopy of CIN and microinvasive cervical carcinoma].

The colposcopist must distinguish between two patterns: nonsuspicious findings and suspicious findings. With experience, the colposcopist will succeed more and more in distinguishing between the two, thereby markedly reducing the number of biopsies. Suspicious findings are not synonymous with abnormal findings because the latter are not always due to premalignant lesions. A number of features are of value in the different diagnosis of colposcopic findings: sharp borders, response to acetic acid (white epithelium), surface contour, appearance of blood vessels, surface extent (size), combinations of abnormalities, iodine uptake, and keratinization. The diagnostic features described above can be expressed to varying degrees, and can be found singly or in combination. The more distinct a feature is and the greater the variety of features seen in combination, the higher the index of suspicion. Attempting to differentiate between the various grades of CIN (SIL) colposcopically is more questionable, as these lesions are regarded now as forming a spectrum of the same biologic process.
