Vaginal misoprostol for cervical ripening and labour induction in late pregnancy.

BACKGROUND: Although not yet registered for such use, misoprostol has been widely used for obstetric and gynaecological indications, such as induction of abortion and of labour. OBJECTIVES: The objective of this review was to assess the effects of vaginal misoprostol for third trimester cervical ripening or induction of labour. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group trials register, the Cochrane Controlled Trials Register and reference lists of articles were searched. SELECTION CRITERIA: Randomised trials comparing vaginal misoprostol with other methods of cervical ripening or labour induction, placebo or no treatment in women due for third trimester induction of labour. DATA COLLECTION AND ANALYSIS: Trial quality assessment and data extraction were done by both reviewers. MAIN RESULTS: Twenty-six studies were included. Compared to placebo, misoprostol was associated with increased cervical ripening (relative risk of unfavourable or unchanged cervix after 12 to 24 hours with misoprostol 0.20, 95% confidence interval 0.07 to 0.61). It was also associated with a reduced need for oxytocin (relative risk 0.47, 95% confidence interval 0.23 to 0.96). Misoprostol was more effective than prostaglandin E2 for labour induction (relative risk of failure to achieve vaginal delivery in 24 hours 0.70, 95% confidence interval 0.62 to 0.79). Oxytocin augmentation was used less often with misoprostol than with prostaglandin E2 (relative risk 0.64, 95% confidence interval 0.58 to 0.71). Uterine hyperstimulation and meconium stained liquor were more common with misoprostol than with prostaglandin E2. Lower doses of misoprostol compared to higher doses did not show significant differences except for more need for oxytocin augmentation and less uterine hyperstimulation without fetal heart rate changes. REVIEWER'S CONCLUSIONS: Vaginal misoprostol appears to be more effective in inducing labour than conventional methods of cervical ripening and labour induction. The apparent increase in uterine hyperstimulation is of concern. The studies were not large enough to exclude the possibility of rare but serious adverse effects.

Determinants of cervical ectopia and of cervicitis: age, oral contraception, specific cervical infection, smoking, and douching.

OBJECTIVE: Our purpose was to assess determinants of cervical ectopia and cervicitis, specifically after adjustment for cervical infection. STUDY DESIGN: A cross-sectional study was conducted with colposcopic, cytologic, and microbiologic examination of 764 randomly selected women attending a sexually transmitted disease clinic and 819 consecutive college students undergoing routine annual examination. RESULTS: After we controlled for potential confounders, cervical ectopia was positively associated with oral contraception and Chlamydia trachomatis infection and negatively associated with aging in both populations, with recent vaginal douching in patients with sexually transmitted diseases, and with current smoking in college students. Oral contraception wa also associated with the radius of ectopia, and among users of oral contraception ectopia was associated with duration of oral contraception. Cervicitis (evaluated by Gram stain, Papanicoloau smear, and colposcopy) was associated with cervical infection by C. trachomatis and cytomegalovirus (both populations) and with gonorrhea and cervical herpes simplex virus infection (patients with sexually transmitted diseases). Cervicitis was independently associated with ectopia but not with oral contraception after we adjusted for these four cervical infections. However, oral contraception was associated with edema and erythema of the zone of ectopia among women without cervical infection. CONCLUSIONS: Oral contraception, aging, cervical infection, smoking, and douching have effects on cervical ectopia that may influence the acquisition, transmission, or effects of sexually transmitted agents. Ectopia is associated with young age, oral contraception, and cervical infection; cervicitis is associated with ectopia and cervical infection by C. trachomatis, Neisseria gonorrhoeae, herpes simplex virus, and cytomegalovirus. In women without cervical infection, edema and erythema of the zone of ectopia are associated with oral contraception.

Increasing the cervical lordosis with chiropractic biophysics seated combined extension-compression and transverse load cervical traction with cervical manipulation: nonrandomized clinical control trial.

BACKGROUND: Cervical lordosis has been shown to be an important outcome of care; however, few conservative methods of rehabilitating sagittal cervical alignment have been reported. OBJECTIVE: To study whether a seated, retracted, extended, and compressed position would cause tension in the anterior cervical ligament, anterior disk, and muscle structures, and thereby restore cervical lordosis or increase the curvature in patients with loss of the cervical lordosis. STUDY DESIGN: Nonrandomized, prospective, clinical control trial. METHODS: Thirty preselected patients, after diagnostic screening for tolerance to cervical extension with compression, were treated for the first 3 weeks of care using cervical manipulation and a new type of cervical extension-compression traction (vertical weight applied to the subject's forehead in the sitting position with a transverse load at the area of kyphosis). Pretreatment and posttreatment Visual Analogue Scale (VAS) pain ratings were compared along with pretreatment and posttreatment lateral cervical radiographs analyzed with the posterior tangent method for changes in alignment. Results are compared to a control group of 33 subjects receiving no treatment and matched for age, sex, weight, height, and pain. RESULTS: Control subjects reported no change in VAS pain ratings and had no statistical significant change in segmental or global cervical alignment on comparative lateral cervical radiographs (difference in all angle mean values < 1.3 degrees ) repeated an average of 8.5 months later. For the traction group, VAS ratings were 4.1 pretreatment and 1.1 posttreatment. On comparative lateral cervical radiographs repeated after an average of 38 visits over 14.6 weeks, 10 angles and 2 distances showed statistically significant improvements, including anterior head weight bearing (mean improvement of 11 mm), Cobb angle at C2-C7 (mean improvement of -13.6 degrees ), and the angle of intersection of the posterior tangents at C2-C7 (mean improvement of 17.9 degrees ). Twenty-one (70%) of the treatment group subjects were followed for an additional 14 months; improvements in cervical lordosis and anterior weight bearing were maintained. CONCLUSIONS: Chiropractic biophysics (CBP) technique's extension-compression 2-way cervical traction combined with spinal manipulation decreased chronic neck pain intensity and improved cervical lordosis in 38 visits over 14.6 weeks, as indicated by increases in segmental and global cervical alignment. Anterior head weight-bearing was reduced by 11 mm; Cobb angles averaged an increase of 13 degrees to 14 degrees; and the angle of intersection of posterior tangents on C2 and C7 averaged 17.9 degrees of improvement.

Nitric oxide metabolites in cervical fluid during pregnancy: further evidence for the role of cervical nitric oxide in cervical ripening.

OBJECTIVE: Cervical tissue expresses all the isoenzymes of nitric oxide synthase. We studied the concentrations of nitric oxide metabolites in the cervical fluid in nonpregnant (n = 11) and pregnant women (n = 106). STUDY DESIGN: Cervical fluid was collected into a Dacron polyester swab, and nitric oxide metabolites were eluted into physiologic saline solution, which was assayed for nitric oxide metabolites with the Griess reaction. The detection limit of the method is 0.2 micromol/L. RESULTS: Cervical fluid nitric oxide metabolite was detectable in 46% of nonpregnant women (median, <0.2 micromol/L; 95% CI, 0-49), in 63% of women in early pregnancy (median, 11 micromol/L; 95% CI, 0-23) and in 82% of women in late pregnancy (median, 128 micromol/L; 95% CI, 21-276). In late pregnancy, the cervical fluid nitric oxide metabolite level was higher in women with Bishop score of > or =6 (median, 163 micromol/L; 95% CI, 105-276) than in women with Bishop score of <6 (median, 86 micromol/L; 95% CI, 21-99). Cervical fluid nitric oxide metabolite concentration before the onset of labor in parous women (median, 97 micromol/L; 95% CI, 78-283) was higher (P =.008) than that in nulliparous women (median, 28 micromol/L; 95% CI, 0-95). Cervical fluid nitric oxide metabolites before the initiation of labor (median, 33 micromol/L; 95% CI, 0-95) rose to 3.5-fold (median, 115 micromol/L; 95% CI, 78-284) after the commencement of uterine contractions and showed a significant relationship to Bishop score (r = 0.39, P =.01). Cervical fluid nitric oxide metabolite concentrations were not relative to simultaneous plasma nitric oxide metabolite levels (n = 41 women, r = 0.14, P =.41). Rupture of fetal membranes tended to decrease cervical fluid nitric oxide metabolite levels, whereas gentle cervical manipulation elevated it 6.6-fold in 1 minute. The administration of glyceryl trinitrate (0.5 mg, nitric oxide donor) intracervically resulted in a significant rise in the cervical fluid nitric oxide metabolite level in 2 minutes. CONCLUSION: Cervical fluid nitric oxide metabolite level rises after cervical ripening, nitric oxide donor administration, or cervical manipulation, which supports a role for cervical nitric oxide in cervical ripening.

Pallidal deep brain stimulation in patients with cervical dystonia and severe cervical dyskinesias with cervical myelopathy.

OBJECTIVES: Surgical treatment of complex cervical dystonia and of cervical dyskinesias associated with cervical myelopathy is challenging. In this prospective study, the long term effect of chronic pallidal stimulation in cervical dystonia and on combining the technique with spinal surgery in patients with severe cervical dyskinesias and secondary cervical myelopathy is described. METHODS: Eight patients with a history of chronic dystonia who did not achieve adequate benefit from medical treatment or botulinum toxin injection participated in the study. Five patients had complex cervical dystonia with tonic postures and phasic movements. Three patients had rapidly progressive cervical myelopathy secondary to severe cervical dyskinesias and dystonia in the context of a generalised movement disorder. Quadripolar electrodes were implanted in the posteroventral lateral globus pallidus internus with stereotactic CT and microelectrode guidance. In the three patients with secondary cervical myelopathy, spinal surgery was performed within a few weeks and included multilevel laminectomies and a four level cervical corporectomy with spinal stabilisation. RESULTS: Improvement of the movement disorder was noted early after pallidal surgery, but the full benefit could be appreciated only with a delay of several months during chronic stimulation. Three months after surgery, patients with cervical dystonia had improved by 38% in the severity score, by 54% in the disability score, and by 38% in the pain score of a modified version of the Toronto western spasmodic torticollis rating scale. At a mean follow up of 20 months, the severity score had improved by 63%, the disability score by 69%, and the pain score by 50% compared with preoperatively. There was also sustained amelioration of cervical dyskinesias in the three patients who underwent spinal surgery. Lead fractures occurred in two patients. The mean amplitude needed for chronic deep brain stimulation was 3.8 V at a mean pulse width of 210 micros, which is higher than that used for pallidal stimulation in Parkinson's disease. CONCLUSIONS: Chronic pallidal stimulation is effective for complex cervical dystonia and it is a useful adjunct in patients with cervical dyskinesias and secondary cervical myelopathy who undergo spinal surgery.

"Disproportion theory" of the cervical spine and spinal cord in patients with juvenile cervical flexion myelopathy. A study comparing cervical magnetic resonance images with those of normal controls.

BACKGROUND: Cervical flexion myelopathy is quite a rare condition affecting mainly adolescent males who present with muscular atrophy of the upper extremities. Its etiology is still unknown, as is the cause of its marked male preponderance. Disproportion of the cervical spine and spinal cord is suspected to be one of the etiological causes, however, this has yet to be confirmed. METHODS: We performed a comparative study of the cervical magnetic resonance (MR) images of six male patients with juvenile cervical flexion myelopathy and of 34 young, normal controls. RESULTS: In normal controls, the cervical spines and spinal cords were significantly straighter in tall than in short males and in females than in males. In these patients, the cervical spine and spinal cord shapes were straighter, and the cervical spine length/height and cervical spinal cord length/height ratios were significantly higher than those of the height-matched male group. In the female group, the cervical spine and cervical spinal cord shapes were similar to the patient group; however, the cervical spine length/height and spinal cord length/height ratios as well as the heights were significantly smaller than those of the patients. CONCLUSIONS: The cervical spinal cords of the patients were considered to be stretched even with the neck in neutral position, reflecting disproportion of the cervical spine and spinal cord. The shorter length of the cervical spine and spinal cord in females was suspected to be one of the reasons for the marked male preponderance.

Factors associated with an increased risk of prevalent and incident grade III cervical intraepithelial neoplasia and invasive cervical cancer among women with Papanicolaou tests classified as grades I or II cervical intraepithelial neoplasia.

OBJECTIVE: Women with Papanicolaou tests classified as cervical intraepithelial neoplasia grade I or II are treated conservatively in many countries. However, these women are at an increased risk of having underlying prevalent and incident grade III cervical intraepithelial neoplasia and invasive cancer. This study was undertaken to identify factors that could predict these clinically important disease states. STUDY DESIGN: Five hundred women with Papanicolaou tests classified as persistent grade I or II cervical intraepithelial neoplasia underwent a repeat test, human papillomavirus testing with Hybrid Capture assay (Digene, Silver Spring, Md) and polymerase chain reaction, and colposcopy with histologic assessment. One hundred fifty-seven women with histologically proven grade I or II cervical intraepithelial neoplasia were monitored conservatively for a minimum of 9 months to assess predictors of incident grade III cervical intraepithelial neoplasia. RESULTS: One hundred fifty-one women with prevalent grade III cervical intraepithelial neoplasia and 5 women with prevalent invasive cancer were identified at the first colposcopy. A repeated Papanicolaou test classified as higher than grade II cervical intraepithelial neoplasia and detection of oncogenic human papillomavirus types were significant predictors of underlying grade III cervical intraepithelial neoplasia and cancer in the multivariate analysis. Seventeen of 157 women (10.8%) with grade I or II cervical intraepithelial neoplasia progressed to grade III cervical intraepithelial neoplasia. Age >30 years and detection of oncogenic human papillomavirus were significantly correlated with progression in the multivariate analysis. No progression was observed in women who were negative for human papillomavirus. CONCLUSION: The high rate of underlying prevalent grade III cervical intraepithelial neoplasia and cancer found in our study (31.2%) indicates that conservative management of women with persistent grade I or II cervical intraepithelial neoplasia should be discouraged. Colposcopy with histologic assessment should be recommended as the standard of care. However, for women with histologically proven grade I or II cervical intraepithelial neoplasia, subsequent conservative management was safe in our study for those who were negative for human papillomavirus by type-specific polymerase chain reaction.

Segmental cervical spine movement with the intubating laryngeal mask during manual in-line stabilization in patients with cervical pathology undergoing cervical spine surgery.

UNLABELLED: We quantified the extent and distribution of segmental cervical movement produced by the intubating laryngeal mask (ILM) during manual in-line stabilization in 20 anesthetized patients with cervical pathology undergoing cervical spine surgery. All patients had neurological symptoms preoperatively. The ILM was inserted with the head and neck in the neutral position. Intubation was facilitated by transillumination of the neck with a lightwand. Cervical movement was recorded with single-frame lateral radiographic images taken 1) immediately before induction (baseline); 2) during ILM insertion (insertion); 3) when transillumination was first seen at the cricothyroid membrane (intubation A); 4) when the tube was being advanced into the trachea (intubation B); and 5) during ILM removal (removal). Radiographic images were digitized and the degree of flexion/extension and posterior movement measured for the occiput (C0) through to C5. During ILM insertion, C0-5 were flexed by an average of 1-1.6 degrees (all P < 0.05). During intubation A/B, C0-4 were flexed by an average of 1.4-3.0 degrees (all P < 0.01), but C5 was unchanged. During ILM removal, C0-3 were flexed by an average of 1 degree (all: P < 0.05), but C3-5 were unchanged. During insertion and intubation A/B, C2-5 were displaced posteriorly by an average of 0.5-1.0 mm (all: P < 0.05). During removal, there was no change at C1-5. Neurological symptoms improved in all patients. We conclude that the ILM produces segmental movement of the cervical spine despite manual in-line stabilization in patients with cervical spine pathology undergoing cervical spine surgery. This motion is in the opposite direction to direct laryngoscopy, suggesting that different approaches to airway management may be more appropriate depending on the nature of the cervical instability. IMPLICATIONS: The intubating laryngeal mask produces segmental movement of the cervical spine, despite manual in-line stabilization in patients with cervical spine pathology undergoing cervical spine surgery. This motion is in the opposite direction to direct laryngoscopy, suggesting that different approaches to airway management may be more appropriate depending on the nature of the cervical instability.

Quantitative determination of the epidermal growth factor receptor in cervical cancer and normal cervical epithelium by 2-color flow cytometry: evidence for down-regulation in cervical cancer.

Expression of epidermal growth factor receptor (EGFR) was quantified by 2-color flow cytometry in cervical cancer (n = 73) and normal cervical epithelium (n = 11). EGFR was determined using a murine monoclonal EGFR antibody, and number of bound antibodies was quantified adding calibration beads with defined antigenic binding sites. Tumor cells were identified by simultaneous DNA staining. Epithelium of normal cervical tissue was detected by labeling for cytokeratin. Results were compared with EGFR quantification by autoradiography on cryostat sections using a radioligand binding assay. A high degree of correlation was found between the 2 methods. In cervical carcinomas 14,600 binding sites/cell (median; range, 160-283,000 binding sites/cell) were detected, considerably less compared with normal cervical squamous epithelium, which was 30,700 binding sites/cell (median; range, 19,900-44,000 binding sites/cell). This finding clearly contrasts with other reports of enhanced EGFR expression in cervical cancer. The discrepancy may be explained by contamination of tissue homogenates used for radioligand or enzyme immunosorbent assays by non-epithelial tissue elements with low or absent EGFR expression. Interference with quantitative EGFR determination in epithelial cells may result in false low estimates of EGFR expression predominantly in normal cervical tissue. This should be avoided by identifying tumor and normal epithelial cells prior to analysis. In our study, 63% of cervical cancers expressed low levels of EGFR compared with normal cervical epithelium, and only 10% showed overexpression. There is evidence that cervical carcinomas overexpressing EGFR represent a small, but biologically distinct group of cervical cancers exhibiting enhanced aggressiveness associated with poor survival of the patients.

Palliative occipito-cervical stabilization in patients with malignant tumors of the occipito-cervical junction and the upper cervical spine.

BACKGROUND: Occipital-cervical stability may be impaired in patients with primary malignant or metastatic tumors of the cranio-cervical junction and the upper cervical spine. The purpose of this study was to evaluate occipital-cervical fixation with pre-bent titanium-loops and sublaminar wiring in order to achieve a rigid and safe stabilisation of the occipito-cervical region in this group of patients. METHOD: 20 patients with severe impairment of occipito-cervical stability due to primary malignant or metastatic cervical bone involvement were included in this study. For palliation of symptoms, resulting from destructive instability, a stabilization procedure using Ransford Loops with sublaminar cable fixation was used in these patients as a palliative therapeutic concept. FINDINGS: Pain which was the major symptom in all patients treated, showed good and immediate response to the stabilization procedures. All 20 patients were either pain free or had good improvement with less intake of analgesic drugs. Signs of spinal cord compression like spasticity and quadraparesis were less likely to improve after surgery. However in 3 of 5 patients neurological function improved after surgery whereas in 2 patients no improvement was achieved. INTERPRETATION: In all patients with impaired occipito-cervical stability due to primary malignant or metastatic tumors of the occipito-cervical junction and the upper cervical spine, immediate stabilization resulting in an improvement of pain was achieved. Occipito-cervical stabilization using contoured Ransford loops is a promising palliative therapeutic concept in this group of patients.

The role of human papillomavirus deoxyribonucleic acid assay and repeated cervical cytologic examination in the detection of cervical intraepithelial neoplasia among human immunodeficiency virus-infected women. Cervical Disease Study Group of the American Foundation for AIDS Research Community Based Clinical Trials Network.

OBJECTIVES: We sought to measure the characteristics of a quantitative human papillomavirus deoxyribonucleic acid assay and repeated cervical cytologic examination in screening for cervical intraepithelial neoplasia among human immunodeficiency virus-infected women. STUDY DESIGN: Human immunodeficiency virus-infected women with screening CD4+ lymphocyte counts of < or = 500 cells/mm3 (n = 103) were examined by quantitative human papillomavirus deoxyribonucleic acid assay and serial cervical cytologic examination and by colposcopy with biopsy and endocervical curettage during the course of 1 year. RESULTS: Quantitative measures of total human papillomavirus deoxyribonucleic acid and high-risk human papillomavirus deoxyribonucleic acid were strongly associated with any cervical intraepithelial neoplasia (P = .005) and high-grade cervical intraepithelial neoplasia (P = .0006), but they improved the sensitivity and negative predictive value of baseline screening only slightly when combined with cervical cytologic examination. Incident cervical intraepithelial neoplasia occurred frequently (20%) during 1 year of follow-up and was more common among human papillomavirus-infected women. Repeated cytologic examination identified 60% of women with new cervical intraepithelial neoplasia. CONCLUSION: Human immunodeficiency virus-infected women with at least mild immunosuppression have a high incidence of cervical intraepithelial neoplasia, which warrants close follow-up. Those with high baseline human papillomavirus deoxyribonucleic acid levels may be at the highest risk for incident cervical intraepithelial neoplasia.

Cervical fetal fibronectin correlates to prostaglandin E2-induced cervical ripening and can be identified in cervical tissue.

OBJECTIVE: Our purpose was to investigate whether prostaglandin E2-induced cervical ripening can be related to changes in fetal fibronectin levels and whether fetal fibronectin can be detected by immunohistochemistry in amniotic and cervical tissue. STUDY DESIGN: Fetal fibronectin levels in cervical mucus were quantitated in 28 nulliparous term pregnant women with unfavorable cervical states before and after intracervical application of prostaglandin E2 gel. The concentration of fetal fibronectin was determined with use of an enzyme immunoassay. Cervical biopsy specimens and amniotic tissue for immunohistochemical analysis were obtained from three term pregnant women and after parturition in three women. Cervical biopsy specimens from two nonpregnant women served as controls. Immunohistochemical analysis was performed with antibodies directed toward fetal fibronectin. RESULTS: The fetal fibronectin level in cervical mucus was low in all women before prostaglandin E2 application. In women with a successful prostaglandin E2-induced ripening (i.e., an increase of cervical score with > or =3 points), a tenfold increase in the fetal fibronectin level was registered. In women with an insufficient cervical ripening after prostaglandin E2 treatment no significant increase in the fetal fibronectin level was registered. The immunohistochemical analyses have identified fetal fibronectin in the epithelial cells of the cervix uteri. CONCLUSION: Successful prostaglandin E2-induced cervical ripening seems to be related to a significant increase in cervical fetal fibronectin levels. Fetal fibronectin can be detected immunohistochemically in the pregnant human cervix.

Cervical intraepithelial lesions and cervical cancer among Asian Pacific Islander women in a cervical cancer screening program.

Utilizing data from a cervical cancer screening program in California, we examined the relationship between being a woman of Asian/Pacific Islander (API) origin and receiving different types of abnormal cervical diagnoses. Initial descriptive data reflected a higher than expected percentage of API subjects with a final diagnosis of in situ and invasive cervical cancer when compared with other subjects in other ethnic groups (N = 2792). Results of multivariate analysis indicated that being of API origin retained significance in a model explaining the level of severity of the cervical final diagnosis, even when controlling for other significant predictors such as having a prior pap smear, age, referral source, the presence of cervical abnormalities and the time from screening to diagnosis. We conclude that women of API origin may not be accessing health care sufficiently early to prevent increasingly severe final diagnoses.

The clinician's view: role of human papillomavirus testing in the American Society for Colposcopy and Cervical Pathology Guidelines for the management of abnormal cervical cytology and cervical cancer precursors.

The American Society for Colposcopy and Cervical Pathology (ASCCP) National Consensus Conference for the Management of Women With Cervical Cytological Abnormalities and Cervical Cancer Precursors was held on the National Institutes of Health campus in Bethesda, Md, September 6-8, 2001. The conference was attended by 121 representatives from 29 national organizations interested in cervical cancer screening issues. For the first time, guidelines for the management of women with abnormal cervical cytology, developed from evidence-based literature, were presented to delegates from the majority of organizations with interest in cervical cancer screening, voted on, and revised when necessary to achieve a majority two-thirds approval. This development of consensus-approved guidelines is likely to be considered one of the most important milestones to date in the management of women with abnormal cervical cytology. The timing of this Consensus Conference resulted from the convergence of many different factors, including new cytologic terminology developed at the Bethesda 2001 workshop and publication of the enrollment data from the National Cancer Institute's Atypical Squamous Cells of Undetermined Significance (ASC-US)/Low-Grade Squamous Intraepithelial Lesions (LSIL) Triage Study, otherwise known as ALTS. Additionally, new preliminary longitudinal ALTS data provided much of the information on the natural history of abnormal Papanicolaou tests and cervical intraepithelial neoplasia (CIN), as well as data on the performance of both new liquid-based cytology and human papillomavirus (HPV) DNA testing in the management of women following colposcopy. The result was a large database of new information that provided the foundation for the ASCCP Consensus Conference. This article covers only the recommendations of the ASCCP Guidelines that were based in large part on the results of the ALTS trial. Therefore, the focus is on the management of women with equivocal (ASC-US) and low-grade (LSIL) cytologic abnormalities. Management of women with these cytologic abnormalities has been particularly problematic, because individually these women are at least risk for CIN 3 and cancer, yet their sheer numerical dominance ensures that they account for the majority of high-grade CIN detected in the United States in the follow-up of abnormal cervical cytology. Data from ALTS confirmed that women with ASC-US could be safely managed by any of the conventional approaches (repeat Papanicolaou test, immediate colposcopy, or HPV testing), but that the preferred management approach for women having an ASC-US report from liquid-based cytology was to assess the patient's risk by testing for HPV. Additionally, longitudinal ALTS data determined that repeat liquid-based cytology at 6 and 12 months and an HPV test at 12 months were nearly equivalent options in the follow-up of women referred for HPV-positive ASC or LSIL, yet not found to have CIN 2+ at initial colposcopy. Therefore, all follow-up recommendations for women with CIN 1 or lower postcolposcopy findings include these 2 options. The data and the recommendations for the management of ASC-US, ASC cannot exclude high-grade squamous intraepithelial lesion, and LSIL are discussed.

Cervical tissue uptake of all-trans-retinoic acid delivered via a collagen sponge-cervical cap delivery device in patients with cervical dysplasia.

The present study was undertaken to evaluate the systemic absorption and cervical tissue uptake of all-trans-retinoic acid (TRA), delivered via a collagen spongecervical cap delivery device in patients with intraepithelial cervical dysplasia. Ten patients with histologically proven mild or moderate cervical dysplasia were included in this pharmacologic study. The two TRA concentrations (0.05% and 0.372%) selected for study represent the starting and maximally tolerated doses used in phase I clinical trial. All-trans-retinoic-11-3H acid (3H-TRA, 500 mu Ci) was used to facilitate cervical tissue uptake studies. Cervical biopsies and post-treatment blood samples were obtained from each patient after TRA exposure. The uptake of TRA into cervical tissues four hours after drug administration was significantly increased at the maximally tolerated TRA dose. There was a rapid decrease in cervical tissue concentration of TRA at the 0.372% dose between 4 and 24 h after drug exposure, suggesting a relatively short elimination half-life of TRA in cervical tissues. HPLC analysis of post-treatment blood samples indicate that there was no systemic absorption of TRA after local cervical administration.

A comparison of anterior cervical fusion, cervical laminectomy, and cervical laminoplasty for the surgical management of multiple level spondylotic radiculopathy.

The risks and success of surgery for multiple level cervical spondylotic radiculopathy differs from that of single level disease. The problems associated with multiple level anterior fusion over single level fusion include higher pseudoarthrosis rates than that associated with single level disease. Bilateral and multiple level laminectomy carries the risk of potential instability. Cervical laminoplasty, until recently, has only been performed for myelopathy secondary to ossification of the posterior longitudinal ligament (OPLL) or cervical stenosis. The purpose of this report is to compare the results and complications of 45 patients with a least a 2-year follow-up who had undergone anterior fusion, cervical laminectomy, or cervical laminoplasty for the surgical management of multiple level cervical radiculopathy due to cervical spondylosis. 18 patients (58 levels) underwent anterior fusion, 12 patients (38 levels) had a cervical laminectomy, and 15 patients (57 levels) underwent a cervical laminoplasty. Roentgenograms indicated spinal stenosis (sagittal diameter less than 12 mm) at 28 levels (15 patients) for the anterior fusion group, 14 levels (9 patients) in the laminectomy group, and 24 levels (13 patients) in the laminoplasty group. Subluxation (2 mm or less) was present at 14 levels (13 patients) in the anterior fusion group, nine levels (9 patients) in the laminectomy group, and 15 levels (8 patients) in the laminoplasty group. Loss of lordosis was present in eight patients undergoing anterior fusion, six patients undergoing laminectomy, and six patients who had a laminoplasty.(ABSTRACT TRUNCATED AT 250 WORDS)

The role of cytokines in cervical ripening: correlations between the concentrations of cytokines and hyaluronic acid in cervical mucus and the induction of hyaluronic acid production by inflammatory cytokines by human cervical fibroblasts.

OBJECTIVES: The purpose of our study was (1) to explain the relationship between levels of inflammatory cytokines and levels of hyaluronic acid in cervical mucus of pregnant women and (2) to investigate whether cytokines promote hyaluronic acid production by human cervical fibroblasts in vitro. STUDY DESIGN: The concentration of hyaluronic acid, interleukin-1beta, and interleukin-8 were measured in cervical mucus of pregnant women, and hyaluronic acid production by cytokine-treated (interleukin-1beta and interleukin-8) cultured fibroblasts was measured. RESULTS: Hyaluronic acid concentrations in the mucus of pregnant women with threatened premature labor were higher than in mucus of normal pregnant women (P < .05). Correlations were found between hyaluronic acid concentrations and interleukin-1beta (P = .018) and interleukin-8 (P = .003) concentrations in cervical mucus. Cytokines (especially interleukin-8) stimulated hyaluronic acid production by cultured cervical fibroblasts. CONCLUSION: Cytokines induce hyaluronic acid production by human cervical fibroblasts, which may promote cervical ripening.

Use of cervical spine manipulation under anesthesia for management of cervical disk herniation, cervical radiculopathy, and associated cervicogenic headache syndrome.

OBJECTIVE: To demonstrate the benefits of cervical spine manipulation with the patient under anesthesia as an approach to treating a patient with chronic cervical disk herniation, associated cervical radiculopathy, and cervicogenic headache syndrome. CLINICAL FEATURES: The patient had neck pain with radiating paresthesia into the right upper extremity and incapacitating headaches and had no response to 6 months of conservative therapy. Treatment included spinal manipulative therapy, physical therapy, anti-inflammatory medication, and acupuncture. Magnetic resonance imaging, electromyography, and somatosensory evoked potential examination all revealed positive diagnostic findings. INTERVENTION AND OUTCOME: Treatment included 3 successive days of cervical spine manipulation with the patient under anesthesia. The patient had immediate relief after the first procedure. Her neck and arm pain were reported to be 50% better after the first trial, and her headaches were better by 80% after the third trial. Four months after the last procedure the patient reported a 95% improvement in her overall condition. CONCLUSION: Cervical spine manipulation with the patient under anesthesia has a place in the chiropractic arena. It is a useful tool for treating chronic discopathic disease complicated by cervical radiculopathy and cervicogenic headache syndrome. The beneficial results of this procedure are contingent on careful patient selection and proper training of qualified chiropractic physicians.
