The high burden of cervical cancer in Zambia prompted the Ministry of Health and partners to develop the cervical cancer prevention program in Zambia (CCPPZ) in 2006. Despite this intervention more women continue to die from the disease and there is little understanding of factors that may be linked with abnormal cervical lesions in the general population. We therefore examined if educational attainment is associated with abnormal cervical lesions among Zambian women aged 15 to 49 years. This study used data from the cervical cancer prevention program in Zambia, where a total of 14,294 women aged 15 to 49 years were screened for cervical cancer at nine health facilities between October 2013 and September 2014. The data represents women from six provinces of Zambia, namely Southern, Central, Copperbelt, Luapula, North-western and Eastern provinces. Step-wise logistic regression analysis using the Statistical Package for the Social Sciences (SPSS) version 21 was used to estimate adjusted odds ratios (AOR) and 95% confidence intervals (CIs) for educational attainment with presence of abnormal cervical lesions as outcome. Multiple imputation was further used to obtain the imputed stabilized estimates for educational attainment. The prevalence of abnormal cervical lesions, using the Visual Inspection with Acetic-acid (VIA) test was 10.7% (n = 1523). Educational attainment was inversely associated with abnormal cervical lesions (AOR = 0.75; 95% CI:0.70-0.81, AOR = 0.74; 95% CI:0.68-0.81 and AOR = 0.46; 95% CI:0.41-0.51) among women with primary, secondary and tertiary education, respectively, compared to those with no formal education. We find reduced likelihood of abnormal cervical lesions in educated women, suggesting a differential imbalance with women who have no formal education. These findings may be a reflection of inequalities associated with access to cervical cancer screening, making the service inadequately accessible for lower educated groups. This might also indicate serious limitations in awareness efforts instituted in the formative phases of the program. These findings underline the prevailing need for urgent concerted efforts in repackaging cervical cancer awareness programs targeting women with low or no formal education in whom the risk may be even higher.

Our previous study of whiplash injury found that abnormalities in the cervical muscles cause autonomic dystonia. Further research has found that abnormalities in the cervical muscles cause headache, chronic fatigue syndrome, vertigo, and dizziness. We named this group of diseases cervical neuro-muscular syndrome. Patients treated within a 2-year period from April 1, 2002 to March 31, 2004 reported good outcomes in 83.8% for headache, 88.4% for vertigo and dizziness, 84.5% for chronic fatigue syndrome, 88.0% for autonomic dystonia, and 83.7% for whiplash-associated disorder. A large number of outpatients present with general malaise, including many general physical complaints without identifiable cause. We propose that treatment of the cervical muscle is effective for general malaise.

There is a scarcity of data on the distribution of human papillomavirus (HPV) genotypes in the HIV positive population and in invasive cervical cancer (ICC) in Kenya. This may be different from genotypes found in abnormal cytology. Yet, with the advent of preventive HPV vaccines that target HPV 16 and 18, and the nonavalent vaccine targeting 90% of all ICC cases, such HPV genotype distribution data are indispensable for predicting the impact of vaccination and HPV screening on prevention. Even with a successful vaccination program, vaccinated women will still require screening to detect those who will develop ICC from other High risk (HR) HPV genotypes not prevented by current vaccines. The aim of this review is to report on the prevalence of pHR/HR HPV types and multiple pHR/HR HPV genotypes in Kenya among HIV positive women with normal, abnormal cytology and ICC. PUBMED, EMBASE, SCOPUS, and PROQUEST were searched for articles on HPV infection up to August 2nd 2016. Search terms were HIV, HPV, Cervical Cancer, Incidence or Prevalence, and Kenya. The 13 studies included yielded a total of 2116 HIV-infected women, of which 89 had ICC. The overall prevalence of pHR/HR HPV genotypes among HIV-infected women was 64% (95%CI: 50%-77%). There was a borderline significant difference in the prevalence of pHR/HR HPV genotypes between Female Sex workers (FSW) compared to non-FSW in women with both normal and abnormal cytology. Multiple pHR/HR HPV genotypes were highly prominent in both normal cytology/HSIL and ICC. The most prevalent HR HPV genotypes in women with abnormal cytology were HPV 16 with 26%, (95%CI: 23.0%-30.0%) followed by HPV 35 and 52, with 21% (95%CI: 18%-25%) and 18% (95%CI: 15%-21%), respectively. In women with ICC, the most prevalent HPV genotypes were HPV 16 (37%; 95%CI: 28%-47%) and HPV 18 (24%; 95%CI: 16%-33%). HPV 16/18 gains prominence as the severity of cervical disease increases, with HPV 16/18 accounting for 61% (95%CI: 50.0%-70.0%) of all ICC cases. A secondary prevention program will be necessary as this population harbors multiple pHR/HR HPV co-infections, which may not be covered by current vaccines. A triage based on FSW as an indicator may be warranted.

We evaluated micronucleus and apoptosis occurrence among women with normal smears and women with different kinds of cervical abnormalities, i.e., inflammatory processes and low- and high-grade squamous intraepithelial lesions (N = 12, N = 10 and N = 27, respectively). The sample included 59 women who were seen at a public medical service for cervical cancer prevention in Feira de Santana, Bahia, Brazil. The diagnosis was established by means of cytological, colposcopic, and histopathological examination. Cytogenetic analysis was performed on 2000 cells from each woman and included assessment of micronuclei and nuclear degenerative abnormalities indicative of apoptosis (karyorrhexis, pyknosis and condensed chromatin). Micronucleus frequency was significantly higher in the women with high-grade squamous intraepithelial lesions than in the women without cervical abnormalities or inflammatory processes (P< 0.001) or in the women with low-grade squamous intraepithelial lesions (P < 0.005). The frequency of apoptosis was similar in women without cervical abnormalities and women showing high-grade squamous intraepithelial lesions (P > 0.50), and significantly lower in women without cervical abnormalities and in women showing high-grade squamous intraepithelial lesions than in women showing inflammatory processes or low-grade squamous intraepithelial lesions (P < 0.0001). These results indicate that, in addition to Papanicolaou cervical cytological analysis, it would be useful to use micronucleus analysis to screen women who are at risk of developing cervical cancer. The assessment of nuclear degenerative abnormalities indicative of apoptosis increased the sensitivity of this test.

Objectives To assess incidence of, and risk factors for abnormal anal cytology and anal intraepithelial neoplasia (AIN) 2–3 in HIV-infected women. Study Design This prospective study assessed 100 HIV-infected women with anal and cervical specimens for cytology and high risk HPV testing over three semi-annual visits. Results Thirty-three women were diagnosed with an anal cytologic abnormality at least once. Anal cytology abnormality was associated with current CD4 count <200 cells/mm3, anal HPV infection and history of other sexually transmitted infections (STIs). Twelve subjects were diagnosed with AIN2-3: four after AIN1 diagnosis and four after ≥1 negative anal cytology. AIN2-3 trended towards an association with history of cervical cytologic abnormality and history of STI. Conclusions Repeated annual anal cytology screening for HIV-infected women, particularly for those with increased immunosuppression, anal and/or cervical HPV, history of other STIs, or abnormal cervical cytology, will increase the likelihood of detecting AIN2-3.

While there is controversy regarding utility of screening electrocardiograms (ECGs) in competitive athletes and children exposed to psychostimulants, there is no data on the use of screening ECGs in psychiatric research. We aimed to examine the prevalence and clinical significance of ECG abnormalities and their impact on eligibility for studies. We analysed 500 consecutive ECG reports from physically healthy volunteers who had a negative cardiac history, normal cardiovascular examination and no other significant medical illnesses. For the purpose of this report, all ECGs were over-read by one cardiologist. The mean age of our cohort was 28.3 ± 8.0 years. A total of 112 (22.4%) ECGs were reported as abnormal (14.2%) or borderline (8.2%). These abnormalities were considered clinically insignificant in all but eight subjects (1.6%) who underwent evaluation with an echocardiogram. All echocardiograms were normal. No subject was excluded from studies. After the over-reading, no abnormalities or isolated bradycardia were present in 37 of 112 (33%) ECGs that were initially reported as abnormal or borderline, while minor abnormalities were found in 7 of 204 (3.4%) ECGs that were reported as normal. Although screening ECGs did not detect significant cardiac pathology or affect eligibility for our studies, over 20% of subjects were labelled as having an abnormal or borderline ECG which was incorrect in one-third of cases. Strategies to minimise unintended consequences of screening are discussed. Published 2013. This article is a U.S. Government work and is in the public domain in the USA.

The Forsyth County Cervical Cancer Prevention Project was a community-wide cancer education program to address the problem of cervical cancer incidence and mortality among minority women in Forsyth County, North Carolina. This paper reports program results with regard to increasing compliance with follow-up for abnormal cervical smears. An analysis of trends prior to and after implementation of the educational program was conducted in one private and two public health primary care clinics to provide an assessment of impact of the project in improving compliance with follow-up among black women. A similar analysis also was conducted for white women. The results of medical record reviews of follow-up procedures for 878 abnormal cervical smears suggested a modest program effect among black women. The percentage of black women who returned for follow-up and treatment of an abnormal cervical smear significantly increased during the time the program was in effect. The trend analysis further indicated that the decline did not begin prior to the intervention period and was maintained throughout the duration of the intervention. No significant change in the percentage who returned for follow-up was found for white women.

Cervical Vertigo: Historical Reviews and Advances.

PubMed

Peng, Baogan

2018-01-01

Vertigo is one of the most common presentations in adult patients. Among the various causes of vertigo, so-called cervical vertigo is still a controversial entity. Cervical vertigo was first thought to be due to abnormal input from cervical sympathetic nerves based on the work of Barré and Liéou in 1928. Later studies found that cerebral blood flow is not influenced by sympathetic stimulation. Ryan and Cope in 1955 proposed that abnormal sensory information from the damaged joint receptors of upper cervical regions may be related to pathologies of vertigo of cervical origin. Further studies found that cervical vertigo seems to originate from diseased cervical intervertebral discs. Recent research found that the ingrowth of a large number of Ruffini corpuscles into diseased cervical discs may be related to vertigo of cervical origin. Abnormal neck proprioceptive input integrated from the signals of Ruffini corpuscles in diseased cervical discs and muscle spindles in tense neck muscles secondary to neck pain is transmitted to the central nervous system and leads to a sensory mismatch with vestibular and other sensory information, resulting in a subjective feeling of vertigo and unsteadiness. Further studies are needed to illustrate the complex pathophysiologic mechanisms of cervical vertigo and to better understand and manage this perplexing entity. Copyright © 2017 Elsevier Inc.

2009-01-01

Background We estimated the number of women undergoing cervical cancer screening annually in Italy, the rates of cervical abnormalities detected, and the costs of screening and management of abnormalities. Methods The annual number of screened women was estimated from National Health Interview data. Data from the Italian Group for Cervical Cancer Screening were used to estimate the number of positive, negative and unsatisfactory Pap smears. The incidence of CIN (cervical intra-epithelial neoplasia) was estimated from the Emilia Romagna Cancer Registry. Patterns of follow-up and treatment costs were estimated using a typical disease management approach based on national guidelines and data from the Italian Group for Cervical Cancer Screening. Treatment unit costs were obtained from Italian National Health Service and Hospital Information System of the Lazio Region. Results An estimated 6.4 million women aged 25–69 years undergo screening annually in Italy (1.2 million and 5.2 million through organized and opportunistic screening programs, respectively). Approximately 2.4% of tests have positive findings. There are approximately 21,000 cases of CIN1 and 7,000–17,000 cases of CIN2/3. Estimated costs to the healthcare service amount to €158.5 million for screening and €22.9 million for the management of cervical abnormalities. Conclusion Although some cervical abnormalities might have been underestimated, the total annual cost of cervical cancer prevention in Italy is approximately €181.5 million, of which 87% is attributable to screening.

Objective The main objective of this study was to estimate the prevalence of coronary heart disease (CHD) of high-altitude populations in Nepal determined by an ECG recordings and a medical history. Methods We carried out a cross-sectional survey of cardiovascular disease and risk factors among people living at four different altitude levels, all above 2800 m, in the Mustang and Humla districts of Nepal. 12-lead ECGs were recorded on 485 participants. ECG recordings were categorised as definitely abnormal, borderline or normal. Results No participant had Q waves to suggest past Q-wave infarction. Overall, 5.6% (95% CI 3.7 to 8.0) of participants gave a self-report of CHD. The prevalence of abnormal (or borderline abnormal) ECG was 19.6% (95% CI 16.1 to 23.4). The main abnormalities were: right axis deviation in 5.4% (95% CI 3.5 to 7.7) and left ventricular hypertrophy by voltage criteria in 3.5% (95% CI 2.0 to 5.5). ECG abnormalities were mainly on the left side of the heart for Mustang participants (Tibetan origin) and on the right side for Humla participants (Indo-Aryans). There was a moderate association between the probability of abnormal (or borderline abnormal) ECG and altitude when adjusted for potential confounding variables in a multivariate logistic model; with an OR for association per 1000 m elevation of altitude of 2.83 (95% CI 1.07 to 7.45), p=0.03. Conclusions Electrocardiographic evidence suggests that although high-altitude populations do not have a high prevalence of CHD, abnormal ECG findings increase by altitude and risk pattern varies by ethnicity.

The question of whether Chlamydia trachomatis (Ct) is a cofactor for human Papillomavirus (HPV) in cervical carcinogenesis is still controversial. We conducted a molecular detection study of both infections in 622 Brazilian women, including 252 women with different grades of abnormal cervical cytology and cervical cancer (CC; cases) and 370 women with normal cytology (controls). Although Ct infection did not seem related to CC carcinogenicity, women with abnormal cytology had a significant high rate of Ct infection. Therefore, it is important to adopt protocols for diagnosis and treatment of this bacterium in conjunction with screening for CC in this population. PMID:23128289

Positional Magnetic Resonance Imaging for People With Ehlers-Danlos Syndrome or Suspected Craniovertebral or Cervical Spine Abnormalities: An Evidence-Based Analysis

PubMed Central

2015-01-01

Background Ehlers-Danlos syndrome (EDS) is an inherited disorder affecting the connective tissue. EDS can manifest with symptoms attributable to the spine or craniovertebral junction (CVJ). In addition to EDS, numerous congenital, developmental, or acquired disorders can increase ligamentous laxity in the CVJ and cervical spine. Resulting abnormalities can lead to morbidity and serious neurologic complications. Appropriate imaging and diagnosis is needed to determine patient management and need for complex surgery. Some spinal abnormalities cause symptoms or are more pronounced while patients sit, stand, or perform specific movements. Positional magnetic resonance imaging (pMRI) allows imaging of the spine or CVJ with patients in upright, weight-bearing positions and can be combined with dynamic maneuvers, such as flexion, extension, or rotation. Imaging in these positions could allow diagnosticians to better detect spinal or CVJ abnormalities than recumbent MRI or even a combination of other available imaging modalities might allow. Objectives To determine the diagnostic impact and clinical utility of pMRI for the assessment of (a) craniovertebral or spinal abnormalities among people with EDS and (b) major craniovertebral or cervical spine abnormalities among symptomatic people. Data Sources A literature search was performed using Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid Embase, and EBM Reviews, for studies published from January 1, 1998, to September 28, 2014. Review Methods Studies comparing pMRI to recumbent MRI or other available imaging modalities for diagnosis and management of spinal or CVJ abnormalities were reviewed. All studies of spinal or CVJ imaging in people with EDS were included as well as studies among people with suspected major CVJ or cervical spine abnormalities (cervical or craniovertebral spine instability, basilar invagination, cranial settling, cervical stenosis, spinal cord compression, Chiari malformation). Results No studies were identified that met the inclusion criteria. Conclusions We did not identify any evidence that assessed the diagnostic impact or clinical utility of pMRI for (a) craniovertebral or spinal abnormalities among people with EDS or (b) major craniovertebral or cervical spine abnormalities among symptomatic people relative to currently available diagnostic modalities.

To compare women who recall being informed of an abnormal Pap to those not having this experience relative to attitudes and beliefs pertaining to screening for cervical cancer. Four hundred women were recruited from eight rural Appalachian counties, in 2013 and 2014. Women completed a paper-and-pencil survey after providing written informed consent. Bivariate associations and age-adjusted associations were calculated between the self-reported experience of being told of an abnormal Pap test result and eight attitudes/beliefs relative to the prevention of cervical cancer. Data analyses were performed in 2014. The mean age was 40.2 years (range 30-64 years). Eighteen women chose not to answer the question asking about ever having an abnormal Pap test result, leaving n = 382. Of the 382 women who did answer, 122 (30.6 %) indicated having an abnormal Pap test result and the remaining 260 (65.2 %) indicated never having this experience. With the exception of one item assessing knowledge that HPV is the cause of cervical cancer, between-group differences in attitudes, beliefs, and intent to have a Pap test the next time one is due were not observed. Although we hypothesized that women ever having an abnormal Pap test may have actively sought to learn more about cervical cancer and its prevention, findings suggest that this is not the case. Informing women of an abnormal result could be coupled with a high-intensity counseling designed to improve attitudes and beliefs relative to women's role in protecting themselves from cervical cancer.

Background and Aims The increase in overweight and obese children may be linked to increased rates of dyslipidaemia. The aim was to assess the prevalence of dyslipidaemia and associated risk factors among the Northern Mexican child population. Methods and Results Four hundred and fifty-one subjects aged between 2 and 10 (47.5% girls) took part in the Nuevo León State Survey of Nutrition and Health 2011–2012. According to the 2011 Expert Panel on Integrated Guidelines for Cardiovascular Health and Risk Reduction in Children and Adolescents, serum lipid levels (mg/dL) were categorized into three subgroups (acceptable, borderline-high/low or high/low) as follows: TChol: acceptable <170, borderline-high 170–199, high ≥200; LDL-chol: acceptable <110, borderline-high 110–129, high ≥130; non-HDL-chol: acceptable <120, borderline-high 120–144, high ≥145; HDL-chol: acceptable >45, borderline-low 40–45, low <40; and TG: acceptable <75, borderline-high 75–99, high ≥100 in ≤9 year-old children, and acceptable <90, borderline-high 90–129, and high ≥130 in 10 year-old children. The overall prevalence of borderline-high + high TG, non-HDL-chol, TChol, and LDL-chol was 63.0%, 44.1%, 43.5%, and 29.9%, respectively. The overall prevalence of borderline-low + low HDL-chol was 46.3%. The overall frequency of dyslipidaemia was 54.3%. Thirteen children (2.9%) had all five symptoms of dyslipidaemia. The most common dyslipidaemia was high TG in combination (26.2%) and in isolation (10.6%). Conclusions Half of the children had at least one abnormal lipid concentration. A high TG level was the most frequent dyslipidaemia. Obesity was associated with the occurrence of at least one abnormal lipid level. These findings emphasize the need to pay further attention to the prevention of cardiovascular disease and obesity from an early age. PMID:25793380

High incidence of cervical ribs indicates vulnerable condition in Late Pleistocene woolly rhinoceroses

PubMed Central

2017-01-01

Mammals as a rule have seven cervical vertebrae, a number that remains remarkably constant. Changes of this number are associated with major congenital abnormalities (pleiotropic effects) that are, at least in humans, strongly selected against. Recently, it was found that Late Pleistocene mammoths (Mammuthus primigenius) from the North Sea have an unusually high incidence of abnormal cervical vertebral numbers, approximately ten times higher than that of extant elephants. Abnormal numbers were due to the presence of large cervical ribs on the seventh vertebra, indicating a homeotic change from a cervical rib-less vertebra into a thoracic rib-bearing vertebra. The high incidence of cervical ribs indicates a vulnerable condition and is thought to be due to inbreeding and adverse conditions that may have impacted early pregnancies in declining populations. In this study we investigated the incidence of cervical ribs in another extinct Late Pleistocene megaherbivore from the North Sea and the Netherlands, the woolly rhinoceros (Coelodonta antiquitatis). We show that the incidence of abnormal cervical vertebral numbers in the woolly rhinoceros is unusually high for mammals (15,6%, n = 32) and much higher than in extant Rhinoceratidae (0%, n = 56). This indicates that woolly rhinoceros lived under vulnerable conditions, just like woolly mammoths. The vulnerable condition may well have contributed to their eventual extinction. PMID:28875067

Introduction HIV-positive women have an increased risk of invasive cervical cancer but cytologic screening is effective in reducing incidence. Little is known about cervical screening coverage or the prevalence of abnormal cytology among HIV-positive women in Ukraine, which has the most severe HIV epidemic in Europe. Methods Poisson regression models were fitted to data from 1120 women enrolled at three sites of the Ukraine Cohort Study of HIV-infected Childbearing Women to investigate factors associated with receiving cervical screening as part of HIV care. All women had been diagnosed as HIV-positive before or during their most recent pregnancy. Prevalence of cervical abnormalities (high/low grade squamous intraepithelial lesions) among women who had been screened was estimated, and associated factors explored. Results Overall, 30% (337/1120) of women had received a cervical screening test as part of HIV care at study enrolment (median 10 months postpartum), a third (115/334) of whom had been tested >12 months previously. In adjusted analyses, women diagnosed as HIV-positive during (vs before) their most recent pregnancy were significantly less likely to have a screening test reported, on adjusting for other potential risk factors (adjusted prevalence ratio (APR) 0.62, 95% CI 0.51–0.75 p<0.01 for 1st/2nd trimester diagnosis and APR 0.42, 95% CI 0.28–0.63 p<0.01 for 3rd trimester/intrapartum diagnosis). Among those with a cervical screening result reported at any time (including follow-up), 21% (68/325) had a finding of cervical abnormality. In adjusted analyses, Herpes simplex virus 2 seropositivity and a recent diagnosis of bacterial vaginosis were associated with an increased risk of abnormal cervical cytology (APR 1.83 95% CI 1.07–3.11 and APR 3.49 95% CI 2.11–5.76 respectively). Conclusions In this high risk population, cervical screening coverage as part of HIV care was low and could be improved by an organised cervical screening programme for HIV-positive women. Bacterial vaginosis testing and treatment may reduce vulnerability to cervical abnormalities. PMID:22545087

To evaluate the effectiveness of human papillomavirus (HPV) testing in primary cervical screening. This was a cross-sectional study from the recruitment phase of a prospective randomised trial. Women were screened for HPV in addition to routine cervical cytology testing. Greater Manchester, attendees at routine NHS Cervical Screening Programme. In all, 24 510 women aged 20–64 screened with liquid-based cytology (LBC) and HPV testing at entry. HPV testing in primary cervical screening. Type-specific HPV prevalence rates are presented in relation to age as well as cytological and histological findings at entry. In all, 24 510 women had adequate cytology and HPV results. Cytology results at entry were: 87% normal, 11% borderline or mild, 1.1% moderate and 0.6% severe dyskaryosis or worse. Prevalence of HPV decreased sharply with age, from 40% at age 20–24 to 12% at 35–39 and 7% or less above age 50. It increased with cytological grade, from 10% of normal cytology and 31% of borderline to 70% mild, 86% moderate, and 96% of severe dyskaryosis or worse. HPV 16 or HPV 18 accounted for 64% of infections in women with severe or worse cytology, and one or both were found in 61% of women with severe dyskaryosis but in only 2.2% of those with normal cytology. The majority of young women in Greater Manchester have been infected with a high-risk HPV by the age of 30. HPV testing is practicable as a primary routine screening test, but in women aged under 30 years, this would lead to a substantial increase in retesting and referral rates. HPV 16 and HPV 18 are more predictive of underlying disease, but other HPV types account for 30% of high-grade disease. PMID:16773068

Background Cervical cancer prevention knowledge deficits persist among women living with HIV/AIDS (WLHA) despite increased risk of developing cervical dysplasia/cancer. We examined associations between WLHA’s cervical cancer prevention knowledge and abnormal Pap test history. Methods We recruited 145 urban and rural WLHA from Ryan White-funded clinics and AIDS service organizations located in the southeastern United States between March 2011 and April 2012. For this analysis, women who reported a history of cervical cancer (n=3) or had a complete hysterectomy (n=14), and observations with missing data (n=22) were excluded. Stata/IC 13 was used to perform cross-tabulations and chi-squared tests. Results Our sample included 106 predominantly non-Hispanic Black (92%) WLHA. Mean age was 46.3±10.9 years. Half (50%) had ≤ high school education. One-third (37%) had low health literacy. The majority (83%) had a Pap test <1 year ago and 84% knew that WLHA should have a Pap test every year, once two tests are normal. Many (68%) have had an abnormal Pap test. Abnormal Pap test follow-up care knowledge varied. While 86% knew follow-up care could include a repeat Pap test, only 56% knew this could also include an HPV test. Significantly more women who had an abnormal Pap test knew follow-up care could include a biopsy (p=0.001). Conclusions For WLHA to make informed/shared decisions about their cervical health, they need to be knowledgeable about cervical cancer care options across the cancer control continuum. Providing WLHA with prevention knowledge beyond screening recommendations seems warranted given their increased risk of developing cervical dysplasia/neoplasia. PMID:24928481

Because subclinical hypothyroidism (thyroid-stimulating hormone [TSH] > 4.5 IU/mL) is associated with adverse pregnancy outcome, including early pregnancy loss, TSH is recommended to be titrated to ≤2.5 mIU/L in levothyroxine-treated women before pregnancy. The purpose of this study was to determine whether borderline-subclinical hypothyroidism (borderline-SCH; 2.5 < TSH ≤ 4.5 IU/mL) affects the outcome of subsequent pregnancies in women with unexplained recurrent pregnancy loss (uRPL). After workup for antinuclear antibody (ANA), anti-phospholipid syndrome, thrombophilia, uterine abnormalities, hormone disorders, and/or chromosomal abnormalities, 317 women with a history of uRPL were enrolled. The women were classified into two groups: borderline-SCH, and euthyroidism (0.3 ≤ TSH ≤ 2.5 IU/mL). All women had normal serum free thyroxine (T4) and did not receive levothyroxine before or during the subsequent pregnancy. There were no significant differences in age, number of previous pregnancy losses, number of live births, or body mass index between the borderline-SCH (n = 56) and the euthyroid (n = 261) groups, but the rate of ANA positivity differed significantly (53.6% vs 33.7%, respectively; P = 0.005). The subsequent pregnancy rate did not differ between the two groups (55.4%, 31/56 vs 51.3%, 134/261, respectively). The pregnancy loss rate (<22 weeks of gestation) tended to be higher in the borderline-SCH than the euthyroid group (29.0%, 9/31 vs 17.9%, 24/134), although not significantly so (P = 0.16). Although some subset of uRPL is though to be due to as-yet-unidentified cause(s), borderline-SCH is unlikely to be involved in uRPL. © 2017 Japan Society of Obstetrics and Gynecology.

Breaking evolutionary and pleiotropic constraints in mammals: On sloths, manatees and homeotic mutations

PubMed Central

2011-01-01

Background Mammals as a rule have seven cervical vertebrae, except for sloths and manatees. Bateson proposed that the change in the number of cervical vertebrae in sloths is due to homeotic transformations. A recent hypothesis proposes that the number of cervical vertebrae in sloths is unchanged and that instead the derived pattern is due to abnormal primaxial/abaxial patterning. Results We test the detailed predictions derived from both hypotheses for the skeletal patterns in sloths and manatees for both hypotheses. We find strong support for Bateson's homeosis hypothesis. The observed vertebral and rib patterns cannot be explained by changes in primaxial/abaxial patterning. Vertebral patterns in sloths and manatees are similar to those in mice and humans with abnormal numbers of cervical vertebrae: incomplete and asymmetric homeotic transformations are common and associated with skeletal abnormalities. In sloths the homeotic vertebral shift involves a large part of the vertebral column. As such, similarity is greatest with mice mutant for genes upstream of Hox. Conclusions We found no skeletal abnormalities in specimens of sister taxa with a normal number of cervical vertebrae. However, we always found such abnormalities in conspecifics with an abnormal number, as in many of the investigated dugongs. These findings strongly support the hypothesis that the evolutionary constraints on changes of the number of cervical vertebrae in mammals is due to deleterious pleitropic effects. We hypothesize that in sloths and manatees low metabolic and activity rates severely reduce the usual stabilizing selection, allowing the breaking of the pleiotropic constraints. This probably also applies to dugongs, although to a lesser extent. PMID:21548920

Cervical smear is the most economic and efficient diagnostic tool for the screening of cervical cancer. However, since plastic bags have been used in Guanajuato to transport and store smears, we have observed cytological abnormalities which difficult the diagnosis and lead to false negatives. To describe those abnormalities. Out of 340 women registered in a primary care center in Mexico, 68 were selected through systematic random sampling during 2007. A cervical smear was obtained and placed on two slides. The first sample was allowed to dry but the second one was placed into the plastic bag immediately after fixation. After 15 days all the smears were stained with the Papanicolaou technique. A certified pathologist, blinded about the variable of study, interpreted the samples according to the Bethesda system, and evaluated the presence of necrosis, edema, holes, and opportunistic microorganisms. Of the 68 smears exposed to a humid storage, 36 (53%) were inadequate for diagnosis (Fisher's exact probability < 0.001). From them, 36 (53%) had holes or lagoons, 34 (50%) had edema, 31 (46%) had necrosis, and 15 (22%) had fungus. On the other hand, the 68 dried cervical smears were all adequate for diagnosis and none had the changes or cytological abnormalities. The humid transport and storage of cervical smears produced abnormalities in the normal morphology that could lead to false negative results. The guideline for the handling of cervical smears must stress the importance of allowing the smears to dry completely after fixation and before storing them in plastic bags.

To our knowledge there are only 15 reported cases of pneumatocysts in the cervical spine, but awareness of their existence should help the clinician when diagnosing abnormalities in radiological images. When faced with intravertebral gas, in addition to considering more sinister causes, one should consider the differentials including pneumatocysts. Despite our relative lack of understanding of these benign lesions the knowledge that they can change over time should prevent unnecessary testing or treating. We present a patient who fell down stairs and was found to have cervical intravertebral gas, on computed tomography imaging, with the typical appearance of a pneumatocyst.

Patient navigation (PN) is a system-level strategy to decrease cancer mortality rates by reducing barriers to cancer care. Barriers to resolution among participants in the PN intervention arm with a breast or cervical abnormality in the Patient Navigation Research Program and navigators' actions to address those barriers were examined. Data from seven institutions (2005-2010) included 1,995 breast and 1,194 cervical patients. A stratified Cox proportional hazards regression model was used to examine the effects of barriers on time to resolution of an abnormal screening test or clinical finding. The range of unique barriers was 0 to 12 and 0 to 7 among participants with breast and cervical abnormalities, respectively. About two thirds of breast and one half of cervical participants had at least one barrier resulting in longer time to diagnostic resolution among breast (adjusted hazard ratio [HR], 0.744; p < .001) and cervical (adjusted HR, 0.792; p < .001) participants. Patient- and system-level barriers were most common. Frequent navigator actions were making arrangements, scheduling appointments, referrals, and education. Having a barrier resulted in a delay in diagnostic resolution of an abnormal screening test or clinical finding. Health care systems can use these findings to improve existing PN programs or when developing new programs. Copyright © 2014 Jacobs Institute of Women's Health. Published by Elsevier Inc.

The pathogenesis of adult-onset primary dystonia remains poorly understood. There is variable age-related and gender-related expression of the phenotype, the commonest of which is cervical dystonia. Endophenotypes may provide insight into underlying genetic and pathophysiological mechanisms of dystonia. The temporal discrimination threshold (TDT)-the shortest time interval at which two separate stimuli can be detected as being asynchronous-is abnormal both in patients with cervical dystonia and in their unaffected first-degree relatives. Functional magnetic resonance imaging (fMRI) studies have shown that putaminal activation positively correlates with the ease of temporal discrimination between two stimuli in healthy individuals. We hypothesized that abnormal temporal discrimination would exhibit similar age-related and gender-related penetrance as cervical dystonia and that unaffected relatives with an abnormal TDT would have reduced putaminal activation during a temporal discrimination task. TDTs were examined in a group of 192 healthy controls and in 158 unaffected first-degree relatives of 84 patients with cervical dystonia. In 24 unaffected first-degree relatives, fMRI scanning was performed during a temporal discrimination task. The prevalence of abnormal TDTs in unaffected female relatives reached 50% after age 48 years; whereas, in male relatives, penetrance of the endophenotype was reduced. By fMRI, relatives who had abnormal TDTs, compared with relatives who had normal TDTs, had significantly less activation in the putamina and in the middle frontal and precentral gyri. Only the degree of reduction of putaminal activity correlated significantly with worsening of temporal discrimination. These findings further support abnormal temporal discrimination as an endophenotype of cervical dystonia involving disordered basal ganglia circuits. © 2014 International Parkinson and Movement Disorder Society.

High oncogenic-risk human papillomavirus (hrHPV) is necessary, although insufficient, to promote cervical cancer. Like HPV, Epstein-Barr virus (EBV) is a common pathogen with the capacity to promote epithelial neoplasms. We examined the association between cervical EBV, hrHPV, and cytology in female sex workers in Nairobi, Kenya. Women (n=332) with known cervical cytology and hrHPV mRNA results were evaluated for cervical EBV DNA by conventional PCR. Prevalence ratios (PR) were calculated to assess the relationships between EBV, hrHPV and cervical cytology. Prospective analyses utilized risk ratios (RR) and time-to-event analyses to determine the association of EBV with hrHPV clearance and abnormal cytology outcomes. Baseline prevalence of hrHPV and EBV was 29% and 19%, respectively. Higher EBV prevalence was found among women with older age, HIV, hrHPV, abnormal cytology, Mycoplasma genitalium infection, smoking habits, younger age at sexual debut and less frequent condom use. At baseline, women with EBV had a higher prevalence of hrHPV infection than EBV-negative women (52% versus 24%; HIV-adjusted PR [95% CI]: 1.8 [1.3, 2.6]). EBV-positive women had a higher prevalence than EBV-negative women of high-grade precancer (15% versus 2%), and abnormal cytology (37% versus 15%), although HIV- and hrHPV-adjusted associations were not significant (high-grade precancer - PR: 2.0 [0.7, 5.9]; abnormal cytology - PR: 1.4 [0.9, 2.2]). In prospective analyses, a marginal association was observed between baseline EBV detection and delayed hrHPV clearance. Our data support a possible role for EBV as a high-risk marker or co-factor for HPV-mediated cervical cancer development.

Primary care providers and health systems have prominent roles in guiding effective cancer screening. To characterize variation in screening abnormality rates and timely initial follow-up for common cancer screening tests. Population-based cohort undergoing screening in 2011, 2012, or 2013 at seven research centers comprising the National Cancer Institute-sponsored Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium. Adults undergoing mammography with or without digital breast tomosynthesis (n = 97,683 ages 40-75 years), fecal occult blood or fecal immunochemical tests (n = 759,553 ages 50-75 years), or Papanicolaou with or without human papillomavirus tests (n = 167,330 ages 21-65 years). Breast, colorectal, or cervical cancer screening. Abnormality rates per 1000 screens; percentage with timely initial follow-up (within 90 days, except 9-month window for BI-RADS 3). Primary care clinic-level variation in percentage with screening abnormality and percentage with timely initial follow-up. There were 10,248/97,683 (104.9 per 1000) abnormal breast cancer screens, 35,847/759,553 (47.2 per 1000) FOBT/FIT-positive colorectal cancer screens, and 13,266/167,330 (79.3 per 1000) abnormal cervical cancer screens. The percentage with timely follow-up was 93.2 to 96.7 % for breast centers, 46.8 to 68.7  % for colorectal centers, and 46.6 % for the cervical cancer screening center (low-grade squamous intraepithelial lesions or higher). The primary care clinic variation (25th to 75th percentile) was smaller for the percentage with an abnormal screen (breast, 8.5-10.3 %; colorectal, 3.0-4.8 %; cervical, 6.3-9.9 %) than for the percentage with follow-up within 90 days (breast, 90.2-95.8 %; colorectal, 43.4-52.0 %; cervical, 29.6-61.4 %). Variation in both the rate of screening abnormalities and their initial follow-up was evident across organ sites and primary care clinics. This highlights an opportunity for improving the delivery of cancer screening through focused study of patient, provider, clinic, and health system characteristics associated with timely follow-up of screening abnormalities.

We performed a multicenter cross-sectional study of 134 sexually active systemic lupus erythematosus (SLE) patients to investigate the prevalence of and risk factors for high risk human papilloma virus (HPV) infection and cervical cytological abnormalities among Korean women with SLE. In this multicenter cross-sectional study, HPV testing and routine cervical cytologic examination was performed. HPV was typed using a hybrid method or the polymerase chain reaction. Data on 4,595 healthy women were used for comparison. SLE patients had greater prevalence of high-risk HPV infection (24.6% vs. 7.9%, P<0.001, odds ratio 3.8, 95% confidence interval 2.5-5.7) and of abnormal cervical cytology (16.4 vs. 2.8%, P<0.001, OR 4.4, 95% CI 2.5-7.8) compared with controls. SLE itself was identified as independent risk factors for high risk HPV infection among Korean women (OR 3.8, 95% CI 2.5-5.7) along with ≥2 sexual partners (OR 8.5, 95% CI 1.2-61.6), and Pap smear abnormalities (OR 97.3, 95% CI 6.5-1,456.7). High-risk HPV infection and cervical cytological abnormalities were more common among Korean women with SLE than controls. SLE itself may be a risk factor for HPV infection among Korean women, suggesting the importance of close monitoring of HPV infections and abnormal Pap smears in SLE patients.

The presence of human immunodeficiency virus type 1 (HIV-1) in genital secretions may be a determinant of vertical HIV-1 transmission. Cervical and vaginal secretions from HIV-1-seropositive pregnant women were evaluated to determine prevalence and correlates of HIV-1-infected cells in the genital tract. HIV-1 DNA was detected by polymerase chain reaction in 32% of 212 cervical and 10% of 215 vaginal specimens. Presence of HIV-1 DNA in the cervix was associated with cervical mucopus and a significantly lower absolute CD4 cell count (354 vs. 469, P < .001). An absolute CD4 cell count <200 was associated with a 9.6-fold increased odds of cervical HIV-1 DNA detection compared with a count > or = 500 (95% confidence interval, 2.8-34.2). Detection of vaginal HIV- 1 DNA was associated with abnormal vaginal discharge, lower absolute CD4 cell count, and severe vitamin A deficiency. Presence of HIV-1-infected cells in genital secretions was associated with immunosuppression and abnormal cervical or vaginal discharge.

The Strengths and Difficulties Questionnaire (SDQ) is widely used to measure emotional and behavioural problems in typically developing young people, although there is some evidence that it may also be suitable for children with intellectual disability (ID). The Developmental Behaviour Checklist - Parent version (DBC-P) is a measure of emotional and behavioural problems that was specifically designed for children and adolescents with an ID. The DBC-P cut-off has high agreement with clinical diagnosis. The aim of this study was to estimate the relationship between DBC-P and SDQ scores in a sample of children with ID. Parents of 83 young people with ID aged 4-17 years completed the parent versions of the SDQ and the DBC-P. We evaluated the concurrent validity of the SDQ and DBC-P total scores, and the agreement between the DBC-P cut-off and the SDQ cut-offs for 'borderline' and 'abnormal' behaviour. The SDQ total difficulties score correlated well with the DBC-P total behaviour problem score. Agreement between the SDQ borderline cut-off and the DBC-P cut-off for abnormality was high (83%), but was lower for the SDQ abnormal cut-off (75%). Positive agreement between the DBC-P and the SDQ borderline cut-off was also high, with the SDQ borderline cut-off identifying 86% of those who met the DBC-P criterion. Negative agreement was weaker, with the SDQ borderline cut-off identifying only 79% of the participants who did not meet the DBC-P cut-off. The SDQ borderline cut-off has some validity as a measure of overall levels of behavioural and emotional problems in young people with ID, and may be useful in epidemiological studies that include participants with and without ID. However, where it is important to focus on behavioural profiles in children with ID, a specialised ID instrument with established psychometric properties, such as the DBC-P, may provide more reliable and valid information. © 2017 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

To report our experience with cephalometry in evaluating velopharyngeal dysfunction (VPD) in velocardiofacial syndrome (VCFS) and its utility in assessing the role of cervical spine abnormalities in VPD, prior to surgical correction of VPD. Clinical charts and cephalometric radiographs done prior to surgery for VPD were retrospectively analyzed to ascertain velopharyngeal measurements and cervical spine abnormalities. Twenty-six patients (age: 6-23 years) with molecularly confirmed VCFS. Wake Forest University Health Sciences (1997-2005). Cranial base angle, nasopharyngeal depth, velum length, and Need ratio at rest, velar dimple location, and velopharyngeal length during phonation; information on presence/absence of submucous cleft palate and cervical spine abnormalities were also obtained. The relationship between C1 anterior arch abnormalities and Need ratio was examined. Seventy-three percent of the VCFS patients had excessive nasopharyngeal depth, 80% had an abnormal Need ratio, 50% had a short velum, 81% had a submucous or occult submucous cleft palate, 90.5% had a cervical spine abnormality (C1 anterior arch abnormalities in 38%) and 11.5% had platybasia. There was a significant difference in the Need ratio between patients with and without C1 anterior arch abnormalities. Cephalometry can be used to delineate factors such as C1 vertebral abnormalities, excessive pharyngeal depth, and short velum that contribute to VPD in VCFS. This would help otolaryngologists better understand the anatomy prior to surgical treatment of VPD. This is the first study to highlight the frequent occurrence of C1 anterior arch abnormalities in VCFS.

Automatic detection of abnormal cells from cervical smear images is extremely demanded in annual diagnosis of women's cervical cancer. For this medical cell recognition problem, there are three different feature sections, namely cytology morphology, nuclear chromatin pathology and region intensity. The challenges of this problem come from feature combination s and classification accurately and efficiently. Thus, we propose an efficient abnormal cervical cell detection system based on multi-instance extreme learning machine (MI-ELM) to deal with above two questions in one unified framework. MI-ELM is one of the most promising supervised learning classifiers which can deal with several feature sections and realistic classification problems analytically. Experiment results over Herlev dataset demonstrate that the proposed method outperforms three traditional methods for two-class classification in terms of well accuracy and less time.

Our aim was to investigate whether high-risk HPV (hrHPV) mRNA detection by PreTect HPV-Proofer can be used to stratify hrHPV DNA-positive women of different cytology classes for risk of high-grade cervical intraepithelial neoplasia or worse (cervical precancer or cancer, i.e., cervical intraepithelial neoplasia grade 2 or higher [≥ CIN2]). A total of 375 women participating in population-based screening, with a GP5+/6+-PCR hrHPV DNA-positive cervical scrape with normal cytology (n = 202), borderline or mild dyskaryosis (BMD) (n = 88), or moderate dyskaryosis or worse (>BMD) (n = 85), were enrolled. Cervical scrapes were additionally subjected to HPV16/18/31/33/45 E6/E7 mRNA analysis by PreTect HPV-Proofer (mRNA test). Referral and follow-up policies were based on cytology, hrHPV DNA, and mRNA testing. The primary study endpoint was the number of ≥CIN2 detected within 3 years of follow-up. The mRNA positivity increased with the severity of cytological abnormality, ranging from 32% (64/202) in hrHPV DNA-positive women with normal cytology to 47% (41/88) in BMD and 68% (58/85) in >BMD groups (P < 0.01). Women with ≥ CIN2 were more likely to test positive by mRNA test (63%) than women without evidence of ≥ CIN2 (32%; P < 0.01). A positive mRNA test result conferred an increased ≥ CIN2 risk in hrHPV DNA-positive women with normal cytology, i.e., 0.55 (95% confidence interval [95% CI], 0.34 to 0.76) in mRNA-positive versus 0.20 (95% CI, 0.07 to 0.33) in mRNA-negative women. In hrHPV DNA-positive women with BMD or >BMD, the result of the mRNA test did not influence the ≥ CIN2 risk. In conclusion, mRNA testing by PreTect HPV-Proofer might be of value to select hrHPV DNA-positive women with normal cytology in need of immediate referral for colposcopy.

The mRNA positivity increased with the severity of cytological abnormality, ranging from 32% (64/202) in hrHPV DNA-positive women with normal cytology to 47% (41/88) in BMD and 68% (58/85) in >BMD groups (P < 0.01). Women with ≥CIN2 were more likely to test positive by mRNA test (63%) than women without evidence of ≥CIN2 (32%; P < 0.01). A positive mRNA test result conferred an increased ≥CIN2 risk in hrHPV DNA-positive women with normal cytology, i.e., 0.55 (95% confidence interval [95% CI], 0.34 to 0.76) in mRNA-positive versus 0.20 (95% CI, 0.07 to 0.33) in mRNA-negative women. In hrHPV DNA-positive women with BMD or >BMD, the result of the mRNA test did not influence the ≥CIN2 risk. In conclusion, mRNA testing by PreTect HPV-Proofer might be of value to select hrHPV DNA-positive women with normal cytology in need of immediate referral for colposcopy. PMID:22553244

Clinicians who manage women with Papanicolaou (Pap) smears showing atypical squamous cells of undetermined significance (ASCUS) may miss clinically significant cervical disease by repeating the cytology alone. We evaluated the ability of the human papillomavirus (HPV) screen and the naked-eye examination after a cervical acetic acid wash to enhance the follow-up Pap smear in predicting an abnormal colposcopic biopsy. Pap smears were performed on all women (N = 7458) attending six family practice offices for a health maintenance examination from August 1989 through February 1991. Consenting subjects with ASCUS underwent repeat cytological testing, an HPV screen, and a cervical acetic acid wash examination immediately before colposcopy after a 4- to 6-month waiting period. Of the 122 consenting women identified with ASCUS, 67 (55%) demonstrated abnormalities on biopsy, including 26 with condyloma, 26 with cervical intraepithelial neoplasia I (CIN I), and 15 with CIN II to III. The false-negative rate, 58%, of the follow-up Pap smear alone for detecting these cases of condyloma and CIN was significantly decreased (false-negative rate, 27%) with the use of the cervical acetic acid wash as an adjunctive test. There was no additional reduction in the false-negative rate with the use of the HPV screen. Of the 15 subjects with high-grade cervical lesions (CIN II to III), 14 had either an abnormal follow-up Pap smear or an abnormal cervical acetic acid wash examination. Among women with cervical atypia, a single follow-up Pap smear alone failed to detect one third of the cases of high-grade disease. Ninety-three percent of these cases were detected, however, with a follow-up Pap smear and an acetic acid wash. Our one subject with a high-grade lesion missed with this combination of tests had an unsatisfactory Pap smear. Use of both tests together may reliably guide clinical decisions regarding the management of cervical atypia.

If human papillomavirus (HPV) testing will replace cytology in primary cervical screening, the frequency of low-grade abnormal screening tests will double. Several available alternatives for the follow-up of low-grade abnormal screening tests have similar outcomes. In this situation, women's preferences have been proposed as a guide for management decisions. To determine women's preferences for the follow-up of low-grade cervical screening abnormalities. Using Medical Subject Headings (MeSH) terms, PubMed was searched for articles published up to December 2010. The reference lists of the retrieved studies were consulted. Studies asking women to state a preference between active follow-up and observation for the management of low-grade abnormalities on screening cytology or HPV tests. Information on study design, participants and outcomes was retrieved using a prespecified form. Studies were sorted by design. Thirteen studies were included in the review. In all five studies that surveyed women with abnormal tests before any management had started, two-thirds preferred active follow-up, predominantly as immediate colposcopy, to observation, predominantly as repeated Pap smears. In all but two studies testing other situations, women more often expressed a preference for active follow-up than for observation; however, women appeared to be somewhat more willing to accept observation if reassured of the low risk of cervical cancer. Even for low-grade abnormal cervical tests, women tend to prefer active management strategies. It may be a challenge to meet their expectations of optimal follow-up when HPV testing is used in primary screening. © 2011 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2011 RCOG.

The adult uterine cervix may exhibit a wide variety of pathologic conditions that include benign entities (eg, cervicitis, hyperplasia, nabothian cysts, cervical polyps, leiomyomas, endometriosis, and congenital abnormalities) as well as malignant lesions, particularly cervical carcinoma. In addition, lesions that arise in the uterine body may secondarily involve the cervix, such as endometrial carcinoma and prolapsed intracavitary masses. Many of these conditions can be identified and characterized at ultrasonography (US), which is considered the first-line imaging examination for the female pelvis. However, examination of the cervix is often cursory during pelvic US, such that cervical disease may be overlooked or misdiagnosed. Transabdominal US of the cervix may not afford sufficient spatial resolution to depict cervical disease in many patients; therefore, endovaginal US is considered the optimal technique. Use of supplemental imaging techniques, particularly the application of transducer pressure on the cervix, may be helpful. This review describes the normal appearance of the cervix at US, the appearance of cervical lesions and conditions that mimic abnormalities at US, and optimal US techniques for evaluation of the cervix. This information will help radiologists detect and diagnose cervical abnormalities more confidently at pelvic US. Online supplemental material is available for this article. (©)RSNA, 2016.

To investigate the prevalence of abnormal cervical cytological findings and local risk factors in Ibadan, Nigeria. All women aged ≥15 years in each household in Idikan, Ibadan, were invited to participate in a population-based study. Structured questionnaires were administered to all consenting women. Conventional cervical Papanicolaou smears obtained from sexually active women were classified using the 2001 Bethesda system. The diagnoses were correlated with sociodemographic data and risk factors. Of 2,870 women aged ≥15 years estimated to live in Idikan, 1,204 sexually active women consented to pelvic examination and cervical smears. Results were available for 1,104 women (mean age: 39.8 years). Mean ages at menarche, first sexual intercourse and first pregnancy were 16.1, 20.3 and 20.7 years, respectively. Cytological results were categorized into atypical squamous cells of undetermined significance and atypical glandular cells 22 (1.99%); low-grade 43 (3.89%) and high-grade squamous intraepithelial lesions (HSIL) 17 (1.54%); invasive cancer 2 (0.18%) and normal 593 (53.8%) and reactive changes 427 (38.7%). The prevalence of epithelial abnormalities is 7.6%. Significant host-related factors in those with HSIL and invasive cancer included older age (mean 56.2 years), high parity and gravidity, lack of formal education and being divorced (p < 0.05). This study provides prevalence data and local risk factors for abnormal cervical cytology in a Nigerian population, which will be useful for planning future cervical cancer control programs.

The presence of human immunodeficiency virus type 1 (HIV-1) in genital secretions may be a determinant of vertical HIV-1 transmission. Cervical and vaginal secretions from HIV-1–seropositive pregnant women were evaluated to determine prevalence and correlates of HIV-1–infected cells in the genital tract. HIV-1 DNA was detected by polymerase chain reaction in 32% of 212 cervical and 10% of 215 vaginal specimens. Presence of HIV-1 DNA in the cervix was associated with cervical mucopus and a significantly lower absolute CD4 cell count (354 vs. 469, P < .001). An absolute CD4 cell count <200 was associated with a 9.6-fold increased odds of cervical HIV-1 DNA detection compared with a count ≥500 (95% confidence interval, 2.8–34.2). Detection of vaginal HIV-1 DNA was associated with abnormal vaginal discharge, lower absolute CD4 cell count, and severe vitamin A deficiency. Presence of HIV-1–infected cells in genital secretions was associated with immunosuppression and abnormal cervical or vaginal discharge. PMID:8985196

To estimate the incidence of abnormal cervical cytology by ThinPrep Pap-tests and cervical intraepithelial neoplasia (CIN) in young adult reproductive-aged Thai women. A total of 1254 women distributed in all regions of Thailand were monitored from 2002 through 2004. Women were screened for abnormal cervical cytology using the ThinPrep method every 6 months. Interpretation of cervical cytology was based on the Bethesda system, version 2001. Women who had the ThinPrep Pap results as atypical squamous cells of undetermined significance or worse underwent colposcopic examination. The ThinPrep and all cervical tissue samples obtained from diagnostic or therapeutic procedures were analyzed and reviewed by Covance Central Laboratory Service, Inc., Indianapolis, USA. The cumulative incidence of abnormal ThinPrep Pap-tests was as follows: 15.3 per 100 woman years (WY) (95% confidence interval [CI] 12.3, 18.9) at 6 months; 12.3 per 100 WY (95% CI 10.3, 14.6) at 12 months; and 11.6 per 100 WY (95% CI 10.0, 13.5) at 18 months. Of 1448.6 woman years of follow up, the incidence of CIN1 was 4.1 per 100 WY (95% CI 3.2, 5.3); CIN2 0.8 per 100 WY (95% CI 0.4, 1.4); and CIN3 0.6 per 100 WY (95% CI 0.3, 1.2). The incidence of abnormal ThinPrep Pap-test and CIN in young adult Thai women had been reported. No comparable data is available.

There have been no reports of the use of 3-Tesla magnetic resonance neurography (3T MRN) to characterize cervical radiculopathy. In particular, there are no reports of MRN of brachial plexus involvement in patients with cervical radiculopathy. We reviewed retrospectively 12 consecutive patients with cervical radiculopathy who underwent 3T MRN. The median age was 54.5 years. Eleven of 12 patients were men. The distribution of nerve-root signal abnormality was correlated with intervertebral foraminal stenosis and the presence of muscles that exhibited weakness and/or signs of denervation on electromyography. MRN abnormalities were found to extend into the distal part of the brachial plexus in 10 patients. This study demonstrates that MRN is potentially useful for diagnosis in patients with suspected cervical radiculopathy. Moreover, the finding of brachial plexus involvement on MRN may indicate a possible pathophysiological relationship between cervical radiculopathy and brachial plexopathy. © 2014 Wiley Periodicals, Inc.

Reliable segmentation of abnormal nuclei in cervical cytology is of paramount importance in automation-assisted screening techniques. This paper presents a general method for improving the segmentation of abnormal nuclei using a graph-search based approach. More specifically, the proposed method focuses on the improvement of coarse (initial) segmentation. The improvement relies on a transform that maps round-like border in the Cartesian coordinate system into lines in the polar coordinate system. The costs consisting of nucleus-specific edge and region information are assigned to the nodes. The globally optimal path in the constructed graph is then identified by dynamic programming. We have tested the proposed method on abnormal nuclei from two cervical cell image datasets, Herlev and H and E stained liquid-based cytology (HELBC), and the comparative experiments with recent state-of-the-art approaches demonstrate the superior performance of the proposed method.

This study aimed to determine population characteristics that correlate to suboptimal follow-up after an abnormal cervical cytology result. Nonpregnant women, ages 21 to 65 years, with newly diagnosed abnormal cervical cytology result between January 2009 and January 2012 at an urban clinic were eligible for inclusion in this retrospective chart review. Cervical cytology data and demographic characteristics such as age, ethnicity, employment, marital and smoking status, health insurance and number of pregnancies were abstracted from electronic medical record. A log-linear model was used to determine which factors influenced patient compliance. Of the total of 206 women, 78 (37.9%) had optimal follow-up and 128 (62.1%) had suboptimal follow-up. The 3 variables that were statistically significant in influencing patient follow-up after adjusted analyses included severity of cytology result (p = .0013), ethnicity (p = .02), and employment status (p = .0159). The risk ratio for optimal follow-up for those with severe cytology result was 1.81; for the non-whites, 1.77; and for the employed, 1.53. Ethnicity, severity of cervical cytology result, and employment status play an important role in patient follow-up after an abnormal cervical cytology result. Detecting trends in our patient population that influence adherence to follow-up will help health care providers formulate strategies that target this problem.

To assess, in a longitudinal study in women diagnosed with high grade squamous epithelial lesion (HSIL), the progression over time of proliferative activity in reserve cells using population screening cervical cytology specimens. Twenty consecutive, unselected patients with HSIL lesions were part of the national cervical screening program. From the archives, for each patient, the last prior normal population screening smear was included in the study. Concurrent sets of cervical smears from 80 age-matched women without pathology formed the controls. The original slides were stained using MIB-1 monoclonal antibody. The fraction of MIB-1-positive reserve cells was assessed using systematic random sampling and running progressive means assessment to ensure a sufficient sample size. The proliferation fraction in reserve cells of HSIL patients was significantly raised (mean, 65.0%; range, 53.5-94.1%; p < 0.01) as compared with that in concurrent controls (mean, 12.8%; range, 1.9-45.4%). Prior smears from HSIL patients, although without morphologic abnormalities, had abnormally high proliferation fractions (mean, 59.1%; range, 1.0-94.7%), significantly raised over those from concurrent controls (mean, 9.4%; range In population-based cervical smear screening, HSIL patients already have abnormally raised proliferation fractions of reserve cells, even without morphologic changes in squamous cells, 1-5 (mean, 3.6) years prior to diagnosis.

An electrocardiogram (ECG) can provide information on subclinical myocardial damage. The presence, and more importantly, the quantity of coronary artery calcification (CAC), relates well with the overall severity of the atherosclerotic process. A strong relation has been demonstrated between coronary calcium burden and the incidence of myocardial infarction, a relation independent of age. The aim of this study was to assess the relation of left ventricular hypertrophy (LVH) and ECG abnormalities with CAC. The study population comprised 566 postmenopausal women selected from a population-based cohort study. Information on LVH and repolarization abnormalities (T-axis and QRS-T angle) was obtained using electrocardiography. Modular ECG Analysis System (MEANS) was used to assess ECG abnormalities. The women underwent a multi detector-row computed tomography (MDCT) scan (Philips Mx 8000 IDT 16) to assess CAC. The Agatston score was used to quantify CAC; scores greater than zero were considered as the presence of coronary calcium. Logistic regression was used to assess the relation of ECG abnormality with coronary calcification. LVH was found in 2.7% (n = 15) of the women. The prevalence of T-axis abnormality was 6% (n = 34), whereas 8.5% (n = 48) had a QRS-T angle abnormality. CAC was found in 62% of the women. Compared to women with a normal T-axis, women with borderline or abnormal T-axes were 3.8 fold more likely to have CAC (95% CI: 1.4-10.2). Similarly, compared to women with a normal QRS-T angle, in women with borderline or abnormal QRS-T angle, CAC was 2.0 fold more likely to be present (95% CI: 1.0-4.1). Among women with ECG abnormalities reflecting subclinical ischemia, CAC is commonly found and may in part explain the increased coronary heart disease risk associated with these ECG abnormalities.

An important internal quality control system used in the Cancer Prevention and Research Institute cytopathology laboratory in Florence is the peer review procedure, based on the review of all abnormal cytological smears which routinely emerge. Peer review is an important training opportunity for all cytologists, especially for those with less experience. This article shows the results of the peer review procedure. Of the 63 754 Papanicolaou (Pap) smears screened in 2011, 1086 were considered to be abnormal [at least atypical squamous cells of undetermined significance (ASC-US+)] on primary screening (selected by a single cytologist) and were subjected to the peer review procedure. The overall performance of the laboratory's cytologists was evaluated using a multiple rater analysis and the comparison of each cytologist with the final diagnosis. Further, the agreement was assessed by means of Cohen's kappa and weighted kappa statistics. In general, a moderate/substantial level of agreement between the ten cytologists and the final diagnoses was evident. Kappa values for each reader compared with the final diagnosis ranged from 0.54 to 0.69. The overall kappa value was 0.62 [95% confidence interval (CI), 0.58-0.66] and overall weighted kappa value was 0.76 (95% CI, 0.74-0.79). The category-specific agreement showed the lowest values for atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion (ASC-H). In summary, peer review represents an important internal quality control in the evaluation and improvement of inter-observer agreement and of the functioning of the laboratory as a whole. Multi-head microscope sessions may improve particularly the reproducibility of borderline diagnoses and, above all, can be an important training contribution for cytologists. © 2014 John Wiley & Sons Ltd.

To determine the prevalence of abnormal cervical smears in a previously unscreened and asymptomatic population in Romania and to compare the data with those from other countries in Europe. In a retrospective study, data were reviewed from smears obtained from women in Romania who had been referred to the gynecologist between January 2006 and December 2011. The smears were collected through 3 regional opportunistic programs of cervical screening and were classified according to the Bethesda system. During the study period, 50536 smear tests were carried out. Of these, 100 smears (0.2%) were unsatisfactory and excluded from the study. Among the remaining 50436 smears, 2965 patients (5.9%) had abnormal epithelial changes. Most of the abnormal smears were represented by atypical squamous cells of undetermined significance (2.6% of all smears). The data confirmed that there is a high prevalence of high-grade intraepithelial squamous-type lesions (0.9% of all smears) in Romania, and of abnormal smears in women younger than 25years of age (14.0% of all abnormal smears). The data show that there is a high prevalence of epithelial abnormalities among cervical smears in Romania compared with other European countries that run a national screening program. © 2013.

To investigate the risk factors associated with abnormal cervical cytology findings in pregnant women. From Sep. 2007 to Sep. 2008, 12,112 pregnant women who underwent their antenatal examinations at 12-36 gestational weeks in Beijing Obstetrics and Gynecology Hospital were enrolled in this study. They were all excluded from the following pathologic obstetrics factors including threatened abortion, premature rupture of membranes or placental previa. Thinprep cytology test (TCT) were given at their first examination, meanwhile, a personal clinic file was established to record her occupation, education, address, family income, nationality, age of first intercourse, number of sex partners, contraception, marriage and pregnancy, current gynecologic diseases, family history of gynecologic tumors, history of gynecologic diseases and smoking and result of pelvic examination. Those risk factors leading to abnormal cervical cytology were analyzed. The complete clinical data were collected from 11 906 cases (98.30%, 11,906/12,112). It was found that 10,354 women were shown with normal TCT result, however, 1134 women (9.52%, 1134/11,906) with atypical squamous cells of undetermined significance (ASCUS), 112 women (0.94%, 112/11,906) with atypical glandular cells of undetermined significance (AGUS), 229 women (1.92%, 229/11,906) with low grade squamous intraepithelial (LSIL), 74 women (0.62%, 74/11,906) with high grade squamous intraepithelial (HSIL). Multiple factorial non-conditioned logistic regression analysis showed that age of first sexual intercourse (OR(ASCUS) = 2.90, OR(AGUS) = 7.32), number of sex partners (OR(ASCUS) = 1.49, OR(AGUS) = 2.02), number of abortion (OR(ASCUS) = 1.68, OR(AGUS) = 3.50) were correlated with ASCUS and AGUS. In LSIL group and HSIL group, age of first sexual intercourse (OR(LSIL) = 6.34, OR(HSIL) = 9.26), number of sex partners (OR(LSIL) = 1.69, OR(HSIL) = 1.65), number of abortion (OR(LSIL) = 1.53, OR(HSIL) = 5.33), smoking (OR(LSIL) = 1.84, OR(HSIL) = 1.77) were remarkable variables. The infection of human papilloma virus (HPV) and trichomonas vaginitis were correlated with abnormal cervical cytology (including ASCUS, AGUS, LSIL and HSIL) significantly (P < 0.01). Columnar epithelium dystopia were also significantly correlated with abnormal cervical cytology (chi(2) = 43.269, P = 0.000). However, abnormal cervical cytology was uncorrelated with degrees of Columnar epithelium dystopia. The risk factors associated with abnormal cervical cytology in pregnant women were the same with those of non-pregnant women.

Background: Human papillomavirus (HPV) testing is more sensitive than cytology for detecting high-grade cervical intraepithelial neoplasia (CIN). We evaluated the performance of high-risk HPV (hrHPV) testing in routine screening. Methods: In all, 25 871 women (29–61) enrolled in our population-based cohort study were offered both cytology and hrHPV testing. High-risk HPV-positive women with normal cytology and an age-matched subcohort of hrHPV-negative women with normal cytology were invited for repeat testing after 1 and/or 2 years and were referred for colposcopy if they presented with abnormal cytology and/or a positive hrHPV test. The hrHPV-positive women with borderline or mild dyskaryosis (BMD) and all women with moderate dyskaryosis or worse (>BMD) were directly referred for colposcopy. Women with BMD and an hrHPV-negative test were advised to repeat cytology at 6 and 18 months and were referred for colposcopy if the repeat cytology test was abnormal. The main outcome measure was CIN grade 3 or worse (CIN3+). Results were adjusted for non-attendance at repeat testing. Results: The hrHPV-positive women with abnormal cytology had a CIN3+ risk of 42.2% (95% confidence interval (CI): 36.4–48.2), whereas the hrHPV-positive women with normal cytology had a much lower risk of 5.22% (95% CI: 3.72–7.91). In hrHPV-positive women with normal cytology, an additional cytology step after 1 year reduced the CIN3+ risk to only 1.6% (95% CI: 0.6–4.9) if the repeat test was normal. The CIN3+ risk in women with hrHPV-positive normal cytology was higher among women invited for the first time (29–33 years of age) (9.1% 95% CI: 5.6–14.3) than among older women (3.0% 95% CI: 1.5–5.5). Conclusion: Primary hrHPV screening with cytology triage in women aged ⩾30 years is an effective way to stratify women on CIN3+ risk and seems a feasible alternative to cytological screening. Repeat cytology after 1 year for hrHPV-positive women with normal cytology is however necessary before returning women to routine screening. PMID:22251922

To measure the effectiveness of the quadrivalent human papillomavirus (HPV) vaccine against cervical abnormalities four years after implementation of a nationally funded vaccination programme in Queensland, Australia. Case-control analysis of linked administrative health datasets. Queensland, Australia. Women eligible for free vaccination (aged 12-26 years in 2007) and attending for their first cervical smear test between April 2007 and March 2011. High grade cases were women with histologically confirmed high grade cervical abnormalities (n = 1062) and "other cases" were women with any other abnormality at cytology or histology (n = 10,887). Controls were women with normal cytology (n = 96,404). Exposure odds ratio (ratio of odds of antecedent vaccination (one, two, or three vaccine doses compared with no doses) among cases compared with controls), vaccine effectiveness ((1-adjusted odds ratio) × 100), and number needed to vaccinate to prevent one cervical abnormality at first screening round. We stratified by four age groups adjusted for follow-up time, year of birth, and measures of socioeconomic status and remoteness. The primary analysis concerned women whose first ever smear test defined their status as a case or a control. The adjusted odds ratio for exposure to three doses of HPV vaccine compared with no vaccine was 0.54 (95% confidence interval 0.43 to 0.67) for high grade cases and 0.66 (0.62 to 0.70) for other cases compared with controls with normal cytology, equating to vaccine effectiveness of 46% and 34%, respectively. The adjusted numbers needed to vaccinate were 125 (95% confidence interval 97 to 174) and 22 (19 to 25), respectively. The adjusted exposure odds ratios for two vaccine doses were 0.79 (95% confidence interval 0.64 to 0.98) for high grade cases and 0.79 (0.74 to 0.85) for other cases, equating to vaccine effectiveness of 21%. The quadrivalent HPV vaccine conferred statistically significant protection against cervical abnormalities in young women who had not started screening before the implementation of the vaccination programme in Queensland, Australia.

The aims of the Fukui Cervical Cancer Screening (FCCS) study are to determine the frequency of women with high-risk HPV (hrHPV), whether HPV16 or HPV18 (HPV16/18), in the Japanese cancer screening population for the first time and to identify the best strategy for cervical cancer screening in Japan. This study enrolled 7,584 women ≥25 years of age who were undergoing routine screening. All women underwent liquid-based cytology and cobas HPV tests. Women with abnormal cytology, whether hrHPV positive or negative; women with hrHPV positivity with either normal or abnormal cytology; and women randomly selected from women with normal cytology and negative hrHPV negative were referred for colposcopy. The prevalences of hrHPV positivity and HPV16/18 positivity were 6.8% and 1.7%, respectively. The baseline data from the FCCS study showed that the combination of HPV tests and cytology was more sensitive than cytology with respect to the detection of intraepithelial neoplasia grade 2 or worse. However, the specificity (94.1%) of the co-testing strategy that required all women with abnormal cytology or hrHPV positivity to be referred for colposcopy was much lower than that (97.8%) of cytology. The sensitivity and specificity of the co-testing strategy that required only women with abnormal cytology or HPV16/18 positivity to undergo colposcopy were 85.5% and 97.0%, respectively. The baseline data from the FCCS study suggest that a cervical cancer screening strategy in which only women with abnormal cytology or HPV16/18 positivity undergo colposcopy offers a more balanced sensitivity and specificity than other strategies.

Electrocardiographic signs of left ventricular hypertrophy (ECG-LVH) and T-wave axis (TA) deviation are independent predictors of fatal and non fatal events. We assessed the prevalence of ECG-LVH, TA abnormalities and their combination according to the presence or absence of diabetes and/or hypertension in a large sample of the adult general Italian population. Data from 10,184 women (54 ± 11 years) and 8775 men (54 ± 11 years) were analyzed from the Moli-sani cohort, a database of randomly recruited adults (age >35) from the general population of Molise, a central region of Italy that includes collection of standard 12-lead resting ECG. Subjects with previous myocardial infarction, angina, cerebrovascular disease or left bundle brunch block or missing values for TA or ECG-LVH have been excluded. TA was measured from the standard 12-lead ECG and it was defined as the rotation of the T wave in the frontal plane as computed by a proprietary algorithm (CalECG/Bravo, AMPS-LLC, NY). ECG-LVH was defined as Sokolow Lyon voltage (SLv) >35 mm or Cornell voltage duration Product (CP) >= 2440 mm*ms. Among subjects with ECG-LVH, prevalence of hypertension was 59.0% and 49.7%, respectively for men and women, whereas that of diabetes was 10.7% and 5.7%. In hypertensives, TA was normal in 72.3% of subjects, borderline in 24.8% and abnormal in 2.9%. In diabetics, TA was normal in 70.4% of subjects, borderline in 26.5% and abnormal in 3.1%. In both hypertensive and diabetic subjects, the prevalence of ECG-LVH, was significantly greater in subjects with borderline or abnormal TA. Hypertension was an independent predictor of abnormal TA (odd ratio: 1.38, P = .025). These results suggest that hypertension might play a relevant role in the pathogenesis of TA deviation. © 2013.

Low-income, inner-city women bear a disproportionate burden of cervical cancer in both incidence and mortality rates in the United States, largely because of low adherence to follow-up recommendations after an abnormal cervical cytology result in the primary care setting. The goals of the present study were to delineate the theory-based psychosocial barriers underlying these persistent low follow-up rates and their sociodemographic correlates. Guided by a well-validated psychosocial theory of health behaviors, this cross-sectional, correlational study assessed the barriers to follow-up adherence among underserved women (N = 210) who received an abnormal cervical cytology result. Participants were recruited through an inner-city hospital colposcopy clinic, and were assessed by telephone prior to the colposcopy appointment. Participants were largely of African American race (82.2%), lower than high school completion education (58.7%), single, never married (67.3%), and without full-time employment (64.1%). Knowledge barriers were most often endorsed (68%, M = 3.22), followed by distress barriers (64%, M = 3.09), and coping barriers (36%, M = 2.36). Forty-six percent reported more than one barrier category. Less education and being unemployed were correlated with higher knowledge barriers (P < .0001 and P < .01, respectively) and more coping barriers (P < .05 and P < .05, respectively). Women who were younger than 30 years displayed greater distress barriers (P < .05). In the primary care setting, assessing and addressing knowledge and distress barriers after feedback of an abnormal cervical cytology result may improve adherence to follow-up recommendations. The use of structured counseling protocols and referral to navigational and other resources may facilitate this process and thereby reduce disparities in cervical cancer. © The Author(s) 2014.

Background Concurrent HPV testing and cervical cytology (co-testing) is an approved and promising alternative to cytology alone in women aged 30 and older. However, broad acceptance of co-testing is being hindered by a lack of evidence about its performance in routine clinical practice. We evaluated the safety of three-year screening intervals for women testing HPV-negative with normal cytology (Pap-negative) and assessed the ability of co-testing to identify women at high risk of CIN3+ or cervical cancer over five years. Methods We analyzed five-year cumulative incidence of cervical cancer and cervical intraepithelial neoplasia grade 3 or worse (CIN3+) for 331,818 women aged 30 and older who enrolled in co-testing at Kaiser Permanente Northern California starting 2003-2005 (and had adequate enrollment co-test results) and were followed through December 31, 2009. Findings Five-year cumulative incidence of cancer for all 315,061 HPV-negative women was extremely low (3.8 per 100,000 women per year), only slightly higher than for the 306,969 women who were both HPV-negative and Pap-negative (3.2 per 100,000 women per year), and half the cancer risk of all 319,177 women who were Pap-negative (7.5 per 100,000 women per year). Almost all (99.5%; 313,465) HPV-negative women had either normal cytology or minor abnormalities. Abnormal cytology greatly increased cumulative incidence of CIN3+ over five years for the 16,757 HPV-positive women (12% vs. 5.9%, p<0.0001). In contrast, although statistically significant, abnormal cytology did not increase 5-year CIN3+ risk for HPV-negative women to a substantial level (0.86% vs. 0.16%). 73% of HPV-positive women had no cytologic abnormality (12,208 women). HPV-positive women with no cytologic abnormality experienced 34% of the CIN3+, 29% of the cancers, and 63% of the adenocarcinomas. Interpretation For women aged 30 and older in routine clinical practice, a single negative HPV test sufficed to provide strong reassurance against cervical cancer over five years, demonstrating the safety of 3-year screening intervals for HPV-negative/Pap-negative women and suggesting that five-year intervals may also be safe. Concurrent HPV testing resulted in earlier identification of the women at high risk of cervical cancer, especially adenocarcinoma. HPV testing without adjunctive cytology may be sufficiently sensitive for primary cervical cancer screening. PMID:21684207

Schistosomal myeloradiculopathy (SMR) is the most severe and disabling form of schistosomiasis. The diagnosis is based on clinical, laboratory, and image data. Vestibular-evoked myogenic potential (VEMP) is a neurophysiologic test that assesses the vestibulospinal pathway through acoustic or galvanic stimuli. The aim of this study was to evaluate cervical spinal abnormalities in patients with SMR. Fifty-two subjects were evaluated, of whom 29 had SMR and 30 did not (normal control). Normal VEMP was observed in all volunteers without SMR. Abnormal VEMP was recorded in 34% of the group with SMR. After treatment, abnormal VEMP was found in 80% of those with persistent neurologic abnormalities. VEMP is a functional test, and the alteration may precede image abnormalities. This procedure may be useful for early diagnosis of schistosomal cervical spinal cord involvement.

We previously developed a new plasma amino acid profile-based index (API) to detect ovarian, cervical, and endometrial cancers. Here, we compared API to serum cancer antigen 125 (CA125) for distinguishing epithelial ovarian malignant tumors from benign growths. API and CA125 were measured preoperatively in patients with ovarian tumors, which were later classified into 59 epithelial ovarian cancers, 21 epithelial borderline malignant tumors, and 97 benign tumors including 40 endometriotic cysts. The diagnostic accuracy and cutoff points of API were evaluated using receiver operating characteristic (ROC) curves. The area under the ROC curves showed the equivalent performance of API and CA125 to discriminate between malignant/borderline malignant and benign tumors (both 0.77), and API was superior to CA125 for discrimination between malignant/borderline malignant lesions and endometriotic cysts (API, 0.75 vs. CA125, 0.59; p < 0.05). At the API cutoff level of 6.0, API and CA125 had equal positive rates of detecting cancers and borderline malignancies (API, 0.71 vs. CA125, 0.74; p = 0.84) or cancers alone (API, 0.73 vs. CA125, 0.85; p = 0.12). However, API had a significantly lower detection rate of benign endometriotic cysts (0.35; 95 % CI, 0.21-0.52) compared with that of CA125 (0.65; 95 % CI, 0.48-0.79) (p < 0.05). API is an effective new tumor marker to detect ovarian cancers and borderline malignancies with a low false-positive rate for endometriosis. A large-scale prospective clinical study using the cutoff value of API determined in this study is warranted to validate API for practical clinical use.

The principal objective was to compare automation-assisted reading of cervical cytology with manual reading using the histological end point of cervical intraepithelial neoplasia grade II (CIN2) or worse (CIN2+). Secondary objectives included (i) an assessment of the slide ranking facility of the Becton Dickinson (BD) FocalPoint™ Slide Profiler (Becton Dickinson, Franklin Lakes, NJ, USA), especially 'No Further Review', (ii) a comparison of the two approved automated systems, the ThinPrep® Imaging System (Hologic, Bedford, MA, USA) and the BD FocalPoint Guided Screener Imaging System, and (iii) automated versus manual in terms of productivity and cost-effectiveness. A 1 : 2 randomised allocation of slides to either manual reading or automation-assisted paired with manual reading. Cytoscreeners were blinded to whether samples would be read only manually or manually paired with automated. Slide reading procedures followed real-life laboratory protocol to produce a final result and, for paired readings, the worse result determined the management. Costs per event were estimated and combined with productivity to produce a cost per slide, per woman and per CIN2+ and cervical intraepithelial neoplasia grade III (CIN3) or worse (CIN3+) lesion detected. Cost-effectiveness was estimated using cost per CIN2+ detected. Lifetime cost-effectiveness in terms of life-years and quality-adjusted life-years was estimated using a mathematical model. Liquid-based cytology samples were obtained in primary care, and a small number of abnormal samples were obtained from local colposcopy clinics, from different women, in order to enrich the proportion of abnormals. All of the samples were read in a single large service laboratory. Liquid residues used for human papillomavirus (HPV) triage were tested (with Hybrid Capture 2, Qiagen, Crawley, UK) in a specialist virology laboratory in Edinburgh, UK. Histopathology was read by a specialist gynaecological pathology team blinded to HPV results and type of reading. Samples were obtained from women aged 25-64 years undergoing primary cervical screening in Greater Manchester, UK, with small proportions from women outside this age range and from women undergoing colposcopy. The principal intervention was automation-assisted reading of cervical cytology slides which was paired with a manual reading of the same slide. Low-grade cytological abnormalities (borderline and mild dyskaryosis) were triaged with HPV testing to direct colposcopy referral. Women with high-grade cytology were referred for colposcopy and those with negative cytology were returned to recall. The principal outcome measure was the sensitivity of automation-assisted reading relative to manual for the detection of CIN2+. A secondary outcome measure was cost-effectiveness of each type of reading to detect CIN2+. The study was powered to detect a relative sensitivity difference equivalent to an absolute difference of 5%. The principal finding was that automated reading was 8% less sensitive relative to manual, 6.3% in absolute terms. 'No further review' was very reliable and, if restricted to routine screening samples, < 1% of CIN2+ would have been missed. Automated and manual were very similar in terms of cost-effectiveness despite a 60%-80% increase in productivity for automation-assisted reading. The significantly reduced sensitivity of automated reading, combined with uncertainty over cost-effectiveness, suggests no justification at present to recommend its introduction. The reliability of 'no further review' warrants further consideration as a means of saving staff time. Current Controlled Trials ISRCTN66377374.

Human papilloma virus (HPV) is the most common sexually transmitted infection in the 21st century. It has been established that infections with specific HPV types are contributing factors to cervical cancer. Approximately 99.7% of cervical cancers are associated with high risk HPV types. HPV testing plays an important role in the prevention, by decreasing the prevalence and the mortality of cervical cancer. There are 16 HPV-centers operating in Hungary, in which patients undergo HPV screening, cervical exams, and treatment based on standardized guidelines. The first HPV-center was founded in 2007 in Budapest, at the 2nd Department of Obstetrics and Gynecology, Semmelweis University. This study aimed to define the presence and prevalence of HPV-DNA in the cervical swab samples obtained from patients in our center. Authors conducted to assess the age-specific-prevalence, and HPV type distribution, the associated cervical abnormalities, comparing our results with international data. Overall 1155 woman underwent HPV-testing and genotyping, using polymerase chain reaction. Overall, 55.5% of patients had positive test for HPV DNA types, in which 38.5% for high-risk HPV DNA. Overall prevalence was the highest among females aged 15 to 25 years (62.9%). The most common HPV type found was the high risk type 16 (19.5% among the patients with positive HPV testing). Presence of high risk HPV with concurrent cervical cytological abnormality was in 32%. More than two-thirds of woman with cytological atypia (70.6%) were infected with two or more high risk HPV types. HPV 16 was detected in 32% of patients with cytological abnormalities. The results suggest that the prevalence of HPV in this study population exceeds the international data. The results attracts the attention the peak prevalence of the high risk types in the youngest age-group, and the higher risk of cervical abnormality in case of presence of two or more HPV types. The dominance of type 16 and 18 was predictable, but the strong attendance of type 51 and 31 among patients who had cytological atypia, was slightly surprising.

Between 1994 and 1999, 837 flexion-extension cervical spine films (F/E) were ordered as part of a protocol to evaluate cervical stability in blunt trauma victims, particularly obtunded patients with otherwise normal films. After 5 years' experience with this protocol, a review of its efficiency and cost-effectiveness was performed. The radiology reports and charts were reviewed for positive or suggestive F/E series. Nearly a third of all series were inadequate to rule out instability. Only four patients were identified who had decreased admission Glasgow Coma Scale score, normal plain films and/or CT, and positive or suggestive findings on F/E. One was felt to be a false positive, and the others had minor or borderline findings; all were treated with continuation of the cervical collar. Although one patient was lost to follow-up, none of the other three required subsequent surgery or developed deformity or neurologic injury. Flexion-extension studies were not a cost-effective part of the protocol, and they were dropped.

Abnormal Papanicolaou smears, genital tract infections, and contraception.

Cervical cancer ranks second among all cancers in women world-wide, and the rate of invasive cervical cancer among women under 50 is rising in the United States. Risk factors for abnormal Papanicolaou (Pap) smears and invasive cervical cancer include genital tract infections. This study was designed to compare the rates of genital tract infections and the contraceptive choices of a random sample of 800 women, using an ex post facto design. The Pap positive women had a significantly higher rate of genital tract infections than did the Pap negative women but did not differ significantly in use of contraceptive methods. Findings support those of other researchers suggesting genital tract infections as risk factors for abnormal Pap smears and are consistent with the literature in suggesting a role for oral contraceptive pills (OCPs) in acquisition of the human papillomavirus (HPV). Caregivers can help empower women to reduce their risks through informed choices about protection and sexual behaviors.

We examined risk of newly detected human papillomavirus (HPV) infection and cervical abnormalities in relation to HPV type 16/18 antibody levels at enrollment in PATRICIA (Papilloma Trial Against Cancer in Young Adults; NCT00122681). Using Poisson regression, we compared risk of newly detected infection and cervical abnormalities associated with HPV-16/18 between seronegative vs seropositive women (15-25 years) in the control arm (DNA negative at baseline for the corresponding HPV type [HPV-16: n = 8193; HPV-18: n = 8463]). High titers of naturally acquired HPV-16 antibodies and/or linear trend for increasing antibody levels were significantly associated with lower risk of incident and persistent infection, atypical squamous cells of undetermined significance or greater (ASCUS+), and cervical intraepithelial neoplasia grades 1/2 or greater (CIN1+, CIN2+). For HPV-18, although seropositivity was associated with lower risk of ASCUS+ and CIN1+, no association between naturally acquired antibodies and infection was demonstrated. Naturally acquired HPV-16 antibody levels of 371 (95% confidence interval [CI], 242-794), 204 (95% CI, 129-480), and 480 (95% CI, 250-5756) EU/mL were associated with 90% reduction of incident infection, 6-month persistent infection, and ASCUS+, respectively. Naturally acquired antibodies to HPV-16, and to a lesser extent HPV-18, are associated with some reduced risk of subsequent infection and cervical abnormalities associated with the same HPV type. © The Author 2014.

Cervical cancer incidence in the US-Affiliated Pacific Islands (USAPIs) is double that of the US mainland. American Samoa, Commonwealth of Northern Mariana Islands (CNMI), Guam and the Republic of Palau receive funding from the Centers for Disease Control (CDC) National Breast and Cervical Cancer Early Detection Program (NBCCEDP) to implement cervical cancer screening to low-income, uninsured or under insured women. The USAPI grantees report data on screening and follow-up activities to the CDC. We examined cervical cancer screening and follow-up data from the NBCCEDP programs in the four USAPIs from 2007 to 2015. We summarized screening done by Papanicolaou (Pap) and oncogenic human papillomavirus (HPV) tests, follow-up and diagnostic tests provided, and histology results observed. A total of 22,249 Pap tests were conducted in 14,206 women in the four USAPIs programs from 2007-2015. The overall percentages of abnormal Pap results (low-grade squamous intraepithelial lesions or worse) was 2.4% for first program screens and 1.8% for subsequent program screens. Histology results showed a high proportion of cervical intraepithelial neoplasia grade 2 or worse (57%) among women with precancers and cancers. Roughly one-third (32%) of Pap test results warranting follow-up had no data recorded on diagnostic tests or follow-up done. This is the first report of cervical cancer screening and outcomes of women served in the USAPI through the NBCCEDP with similar results for abnormal Pap tests, but higher proportion of precancers and cancers, when compared to national NBCCEDP data. The USAPI face significant challenges in implementing cervical cancer screening, particularly in providing and recording data on diagnostic tests and follow-up. The screening programs in the USAPI should further examine specific barriers to follow-up of women with abnormal Pap results and possible solutions to address them. Published by Elsevier Ltd.

A New Perspective on the Pathophysiology of Borderline Personality Disorder: A Model of the Role of Oxytocin.

PubMed

Herpertz, Sabine C; Bertsch, Katja

2015-09-01

Borderline personality disorder is characterized by three domains of dysfunction: affect dysregulation, behavioral dyscontrol, and interpersonal hypersensitivity. Interpersonal hypersensitivity is associated with a (pre)attentive bias toward negative social information and, on the level of the brain, enhanced bottom-up emotion generation, while affect dysregulation results from abnormal top-down processes. Additionally, the problems of patients with borderline personality disorder in interpersonal functioning appear to be related to alterations in the (social) reward and empathy networks. There is increasing evidence that the oxytocinergic system may be involved in these domains of dysfunction and may thus contribute to borderline psychopathology and even open new avenues for targeted pharmacotherapeutic approaches. From studies in healthy and clinical subjects (including first studies with borderline personality disorder patients), the authors provide a conceptual framework for future research in borderline personality disorder that is based on oxytocinergic modulation of the following biobehavioral mechanisms: 1) the brain salience network favoring adaptive social approach behavior, 2) the affect regulation circuit normalizing top-down processes, 3) the mesolimbic circuit improving social reward experiences, and 4) modulating brain regions involved in cognitive and emotional empathy. In addition, preliminary data point to interactions between the oxytocin and cannabinoid system, with implications for pain processing. These mechanisms, which the authors believe to be modulated by oxytocin, may not be specific for borderline personality disorder but rather may be common to a host of psychiatric disorders in which disturbed parent-infant attachment is a major etiological factor.

HPV genotypes and associated cervical cytological abnormalities in women from the Pearl River Delta region of Guangdong province, China: a cross-sectional study

PubMed Central

2014-01-01

Background It is important to understand the specific HPV genotype distribution in screen-detected lesions. HPV Genotype is helpful for separating HPV-positive women at greater risk of cancer from those who can regress spontaneously and for preventing cervical cancer at early stage. The aim of this study was to investigate the high-risk HPV genotype distribution among cervical cytology abnormality in Pearl River Delta Region, Southern China Methods 5585 HPV-infected women were screened from 77069 women in Pearl River Delta Region. Information was obtained from 3226 screened subjects through questionnaires and personal interviews. Exfoliated cervical cells were collected by doctors for HPV test with MassARRAY (Sequenom, Sandiego, CA) technique based on the matrix-assisted laser desorption/ionization time-of flight (MALDI-TOF) mass spectrometry (MS). The ThinPrep cytology test was performed to screen for cervical cancer. Unconditional logistic was used to determine the most common HPV carcinogenic types. Results Of the 3226 HPV-positive samples tested, 1744 (54.1%) with normal cervical cytology, 1482 (45.9%) with abnormal cytology. The five most common HPV types in this study were HPV16 (20.2%), HPV52 (17.1%), HPV58 (13.2%), HPV18 (9.5%), HPV6 (7.6%). Overall, HPV16 (OR = 10.5, 95% CI: 3.7 ~ 29.6), HPV33 (OR = 9.1, 95% CI: 2.8 ~ 29.2), HPV58 (OR = 6.3, 95% CI: 2.1 ~ 18.6), HPV31 (OR = 4.5, 95% CI: 1.3 ~ 15.5), multiple genotype infection (OR = 3.0, 95% CI: 1.7 ~ 14.7), especially HPV16 and HPV33, increased the risk of cytology abnormalities. Conclusions HPV16, HPV31, HPV33, HPV58, and multiple HPV genotype infection increased the risk of cytology abnormalities in Pearl River Delta Region and might be useful for the screening, preventing, treating, and monitoring of pre-cancer lesions in southern China.

In this study the diagnostic potential of synchronous luminescence spectroscopy (SLS) technique for the characterization of normal and different pathological condition of cervix viz., moderately differentiated squamous cell carcinoma (MDSCC), poorly differentiated squamous cell carcinoma (PDSCC) and well differentiated squamous cell carcinoma (WDSSC). Synchronous fluorescence spectra were measured for 70 abnormal cases and 30 normal subjects. Characteristic, highly resolved peaks and significant spectral differences between normal and MDSCC, PDSCC and WDSCC cervical blood formed elements were obtained. The synchronous luminescence spectra of formed elements of normal and abnormal cervical cancer patients were subjected to statistical analysis. Synchronous luminescence spectroscopy provides 90% sensitivity and 92.6% specificity.

Objective The purpose is to determine the prevalence of electrocardiogram (ECG) abnormalities, including borderline and prolonged QT, among screened children with sensorineural hearing loss (SNHL) and to analyze their subsequent medical workup. Study Design Institutional Review Board-approved case series with chart review. Setting Tertiary academic center. Subjects and Methods Cases from 1996 to 2014 involving pediatric patients (N = 1994) with SNHL were analyzed. Abnormal ECGs were categorized as borderline/prolonged QT or other. A board-certified pediatric cardiologist retrospectively determined the clinical significance of ECG changes. For follow-up analysis, children with heart disease, known syndromes, or inaccessible records were excluded. Results Among 772 children who had ECGs, 215 (27.8%) had abnormal results: 35 (4.5%) with QT abnormalities and 180 (23.3%) with other abnormalities. For children with QT abnormalities meeting inclusion criteria (n = 30), follow-up measures included cardiology referral (46.6%), repeat ECG by ear, nose, and throat (ENT) specialist (20%), clearance by ENT specialist with clinical correlation and/or comparison with old ECGs (20%), and pediatrician follow-up (6.7%). Documentation of further workup by ENT or referral was absent for 6.7%. For children with other ECG changes meeting inclusion criteria (n = 136), abnormalities were documented for 57 (41.9%); normal QT without other abnormality was documented for 18 (13.2%). The most common follow-up referrals were to pediatricians (16.9%) and cardiologists (10.3%). Among patients with clinically significant non-QT abnormalities mandating further evaluation (n = 122), 38 (31.1%) had documented follow-up in medical records. Conclusion There is a high prevalence of ECG abnormalities among children with congenital SNHL. If findings are confirmed by future studies, screening should be considered for congenital unilateral or bilateral SNHL, regardless of severity. We describe a standardized protocol for ECG screening/follow-up.

Background: An electrocardiogram (ECG) can provide information on subclinical myocardial damage. The presence, and more importantly, the quantity of coronary artery calcification (CAC), relates well with the overall severity of the atherosclerotic process. A strong relation has been demonstrated between coronary calcium burden and the incidence of myocardial infarction, a relation independent of age. The aim of this study was to assess the relation of left ventricular hypertrophy (LVH) and ECG abnormalities with CAC. Methods: The study population comprised 566 postmenopausal women selected from a population-based cohort study. Information on LVH and repolarization abnormalities (T-axis and QRS-T angle) was obtained using electrocardiography. Modular ECG Analysis System (MEANS) was used to assess ECG abnormalities. The women underwent a multi detector-row computed tomography (MDCT) scan (Philips Mx 8000 IDT 16) to assess CAC. The Agatston score was used to quantify CAC; scores greater than zero were considered as the presence of coronary calcium. Logistic regression was used to assess the relation of ECG abnormality with coronary calcification. Results: LVH was found in 2.7% (n = 15) of the women. The prevalence of T-axis abnormality was 6% (n = 34), whereas 8.5% (n = 48) had a QRS-T angle abnormality. CAC was found in 62% of the women. Compared to women with a normal T-axis, women with borderline or abnormal T-axes were 3.8 fold more likely to have CAC (95% CI: 1.4–10.2). Similarly, compared to women with a normal QRS-T angle, in women with borderline or abnormal QRS-T angle, CAC was 2.0 fold more likely to be present (95% CI: 1.0–4.1). Conclusion: Among women with ECG abnormalities reflecting subclinical ischemia, CAC is commonly found and may in part explain the increased coronary heart disease risk associated with these ECG abnormalities.

Cervical cancer is the second most common of malignancy found in Thai women. Human papillomavirus (HPV) infection is a major cause. The objective of the present study was to evaluate the prevalence of HPV infection and association with abnormal cervical cytology in Thai women. This study was conducted at the Gynecologic Clinic, Thammasat University, Pathum Thani, Thailand. A total of 2,144 cases who underwent annual cervical cancer screening by co-testing (liquid based cytology and HPV testing, DNA versus mRNA) during the priod from July 2013 to June 2016 were recruited in this study. Prevalence of positive high risk (HR) HPV DNA and mRNA test were 19.7 and 8.4%, respectively with a statistically significant difference. Majority of cases of abnormal cytology in this study were atypical squamous cells of undetermined significance (ASC-US). In patients with ASC-US, positive HR HPV DNA was greater than in the mRNA group (10.1 and 4.5%, p<0.001). Nonetheless, there was no significant difference in participants with cervical intraepithelial neoplasia (CIN). HPV mRNA test had slightly lower sensitivity but higher negative predictive value (NPV) than the DNA test to detect abnormal cytology during cervical cancer screening (p<0.001). Both HPV test (DNA and mRNA) had equally efficacy to detect high grade precancerous lesion or higher (CIN 2+). Prevalence of HR HPV DNA and mRNA were 19.7 and 8.4 percent, respectively. NPV of HPV mRNA was higher than DNA test. Both tests had equal efficacy to detect CIN 2+ with sensitivity and specificity of 63% vs 55.7% and 83% vs 92%, respectively.

The purpose of this study was to assess the predictive value of naked-eye inspection of the cervix (NIC) after acetic acid application as an adjunct to Papanicolaou (Pap) testing for cervical cancer screening. Study subjects were women attending a medical college student health clinic either for cervical cytologic screening (67%) or because of a recent atypical cytologic screening result (33%). All study participants received cytologic screening, cervicography, and NIC. Of the 95 patients, 71 (75%) had abnormal findings on NIC. Fifty-one patients underwent colposcopy with biopsy, including 48 of the 71 with an abnormal finding on NIC. The results of 40 of the biopsies were abnormal: 36 showed human papillomavirus or low-grade squamous intraepithelial lesions, 3 showed high-grade squamous intraepithelial lesions, and 1 showed invasive cervical cancer. Sixty-five percent (26) of the abnormal biopsy findings occurred in women with normal cytologic test results. NIC and cervicography both were effective in identifying patients with abnormalities, but the combination of NIC followed by cervicography referred fewer women for colposcopy than did a positive result on NIC alone (52% vs 75%). The combination of a negative Pap smear and a negative NIC result had a 91% predictive value for the absence of cervical intraepithelial neoplasia. This was a significant improvement over cytologic screening alone. In this study, the combination of cytologic screening (Pap smear) and NIC increased the screening yield as compared with a Pap smear alone but with some loss of positive predictive value. NIC significantly improved the predictive value of negative cytologic screening results.

The objective of this study was to determine whether cervicitis in dairy cows is an independent disease or occurs concomitantly with inflammation of the uterus, and to clarify possible effects of cervicitis on reproductive performance. Dairy cows (n = 416) from 33 dairy farms were examined by rectal palpation and vaginoscopy between 42 and 50 days postpartum. Inclusion criteria for this study were absence of abnormal vaginal discharge and abnormalities of the uterus (fluctuation) at rectal palpation. Cervicitis was diagnosed when the second cervical fold was swollen and prolapsed with (C2) or without (C1) reddening. Cytobrush samples from the uterus (n = 370) and the cervix (n = 402) were collected, and the percentage of neutrophils in the uterus (PMNU) and the cervix as indicators of inflammation (threshold: ≥5%) was determined. In addition, endometrial biopsies for histology were collected, 300 of which were suitable for evaluation. Cervicitis (C1/C2) was diagnosed in 253 of 416 (60.8%) of cows. Of these, the prolapsed cervical mucosa was hyperemic (C2) in 29.1% of cases. Of 370 available uterine cytology samples, 221 cows had a clinical cervicitis; however, 170 (76.9%) had PMNU less than 5%. Of 300 uterine histologic examinations, 82 (27.3%) did not reveal any abnormalities; the remaining cows either had uterine inflammation and/or degenerative uterine changes such as endometriosis and angiosclerosis. Furthermore, of 300 biopsied animals, 184 revealed a cervicitis (C1/C2); however, 30.4% of these animals had no histopathologic uterine findings. For further analysis, only animals either without histopathologic findings and normal uterine cytology or with solely endometritis (defined as PMNU ≥ 5% and/or positive histopathology of the uterine tissue) were evaluated (n = 157). Of these, 95 cows had cervicitis. Unexpectedly, 63 of 95 (66.3%) cows had cervicitis without endometritis. With regard to reproductive performance, days to first service were not affected by cervicitis. Number of days open in animals with cervicitis but without endometritis tended to be lower than in cows with cervicitis plus endometritis (P = 0.092). Also, number of days open relative to percentage of neutrophils greater than 5% was lower when the cervical compared to the uterine mucosa was affected (P < 0.05). Total conception and pregnancy rates of animals 200 days into lactation decreased significantly in cows with severe cervical inflammation (C2). In conclusion, the results of this study suggested that cervicitis occurs independent of endometritis, and a higher degree of cervicitis is associated with poorer reproductive performance.

India has the third highest burden of HIV and highest number of cervical cancer in the world. A cross-sectional study was performed to determine the prevalence and types of human papillomavirus (HPV) infection, and the factors associated with HPV infection and abnormal cervical cytology in HIV-positive women attending the Antiretroviral Therapy (ART) Centre in a tertiary care hospital in eastern India. We screened 216 HIV- positive women with Papanicolau smear cytology and HPV testing. HPV DNA was detected by using consensus primers followed by sequencing. Of the 216 HIV-positive women screened, 58 (26.85%) were HPV-positive; 56 (25.9%) were of high-risk (HR) HPV type. The most prevalent HPV type was HPV-16 (7.9%); non 16 and 18 HPV types were present in 17.6 per cent patients. Age ≤ 35 yr [(OR), 2.56 (1.26-5.19)], illiteracy [OR, 2.30 (1.19-4.46)], rural residence [OR, 3.99 (1.27-12.56)] and CD4 ≤ 350/µl [OR, 2.46 (1.26-4.83)] were associated with increased risk of acquisition of HPV. One hundred thirty nine (74.33%) patients had normal/ negative for intraepithelial lesions (NILM) cytology, three (1.60%) had atypical squamous cells of undetermined significance (ASCUS), 32 (17.11%) had low-grade squamous intraepithelial lesions (LSIL), 10 (5.35%) had high-grade squamous intraepithelial lesions (HSIL) and three (1.60%) had carcinoma cervix. WHO clinical Stage III and IV [OR, 2.83 (1.07-7.49)] and CD4 ≤ 350/µl [OR, 2.84 (1.30-6.20)] were risk factors for abnormal cytology. Our study showed 26.85 per cent HPV positivity in HIV infected women in this region, with HPV-16 as the commonest genotype. Abnormal cervical cytology was seen in about 25 per cent women. Regular Pap smear screening as recommended by the National AIDS Control Organization will help in early detection of cervical abnormalities in HIV- positive women.

Worldwide, each year, large numbers of women are referred for colposcopy following low-grade abnormal cervical cytology. Many have no visible abnormality on examination. The risk of cervical intra-epithelial neoplasia grade 2/3 (CIN2/3) in these women is low. It is unknown whether, for women, a normal colposcopy resolves the anxiety which often follows the receipt of an abnormal cytology result. We investigated the prevalence of adverse psychological outcomes over 30 months following a normal colposcopy. This cohort study was nested within the UK TOMBOLA randomized controlled trial. Women aged 20-59 years, with recent low-grade cytology, who had a satisfactory colposcopy examination and normal transformation zone, completed the Hospital Anxiety and Depression Scale (HADS) and Process Outcome Specific Measure (POSM) at recruitment and during follow-up (12, 18, 24 and 30 months post-recruitment). Outcomes included percentages reporting significant anxiety (HADS anxiety subscale score ≥11), significant depression (HADS depression subscale score ≥8) or worries about the result of the next cytology test, cervical cancer, having sex, future fertility and general health at each time point (point prevalence) and during follow-up (cumulative prevalence). The study included 727 women. All psychological measures (except depression) had high prevalence at recruitment, falling substantially by 12 months. During follow-up, the cumulative prevalence of significant anxiety was 27% and significant depression was 21%. The most frequently reported worry was that the next cytology test would be abnormal (cumulative prevalence of 71%; point prevalence of ≥50% at 12 and 18 months). The cumulative prevalence values of worries about cervical cancer, having sex and future fertility were 33%, 20% and 16%, respectively. For some women who have low-grade cytology, a normal colposcopy does not appear to provide psychological reassurance. © 2014 John Wiley & Sons Ltd.

Because of the complexity of cervical cancer prevention guidelines, clinicians often fail to follow best-practice recommendations. Moreover, existing clinical decision support (CDS) systems generally recommend a cervical cytology every three years for all female patients, which is inappropriate for patients with abnormal findings that require surveillance at shorter intervals. To address this problem, we developed a decision tree-based CDS system that integrates national guidelines to provide comprehensive guidance to clinicians. Validation was performed in several iterations by comparing recommendations generated by the system with those of clinicians for 333 patients. The CDS system extracted relevant patient information from the electronic health record and applied the guideline model with an overall accuracy of 87%. Providers without CDS assistance needed an average of 1 minute 39 seconds to decide on recommendations for management of abnormal findings. Overall, our work demonstrates the feasibility and potential utility of automated recommendation system for cervical cancer screening and surveillance.

Laser-induced fluorescence at 337-nm excitation was used in vivo to differentiate neoplastic [cervical intraepithelial neoplasia (CIN)], nonneoplastic abnormal (inflammation and human papilloma viral infection), and normal cervical tissues. A colposcope (low-magnification microscope used to view the cervix with reflected light) was used to identify 66 normal and 49 abnormal (5 inflammation, 21 human papilloma virus infection, and 23 CIN) sites on the cervix in 28 patients. These sites were then interrogated spectroscopically. A two-stage algorithm was developed to diagnose CIN. The first stage differentiated histologically abnormal tissues from colposcopically normal tissues with a sensitivity, specificity, and positive predictive value of 92%, 90%, and 88%, respectively. The second stage differentiated preneoplastic and neoplastic tissues from nonneoplastic abnormal tissues with a sensitivity, specificity, and positive predictive value of 87%, 73%, and 74%, respectively. Spectroscopic differences were consistent with a decrease in the absolute contribution of collagen fluorescence, an increase in the absolute contribution of oxyhemoglobin attenuation, and an increase in the relative contribution of reduced nicotinamide dinucleotide phosphate [NAD(P)H] fluorescence as tissue progresses from normal to abnormal in the same patient. These results suggest that in vivo fluorescence spectroscopy of the cervix can be used to diagnose CIN at colposcopy.

Cervical collars are applied to millions of trauma victims with the intent of protecting against secondary spine injuries. Adverse clinical outcomes during the management of trauma patients led to the hypothesis that extrication collars may be harmful in some cases. The literature provides indirect support for this observation. The purpose of this study was to directly evaluate cervical biomechanics after application of a cervical collar in the presence of severe neck injury. Cranial-caudal displacements in the upper cervical spine were measured in cadavers from images taken before and after application of collars following creation of an unstable upper cervical spine injury. In the presence of severe injury, collar application resulted in 7.3 mm +/- 4.0 mm of separation between C1 and C2 in a cadaver model. In general, collars had the effect of pushing the head away from the shoulders. This study was consistent with previous evidence that extrication collars can result in abnormal distraction within the upper cervical spine in the presence of a severe injury. These observations support the need to prioritize additional research to better understand the risks and benefits of cervical stabilization methods and to determine whether improved stabilization methods can help to avoid potentially harmful displacements between vertebrae.

The aim of this study was to ascertain potential factors associated with cervical spine injuries in children injured during sports and recreational activities. This is a secondary analysis of a multicenter retrospective case-control study involving children younger than 16 years who presented to emergency departments after blunt trauma and underwent cervical spine radiography. Cases had cervical spine injury from sports or recreational activities (n = 179). Comparison groups sustained (1) cervical spine injury from other mechanisms (n = 361) or (2) other injuries from sports and recreational activities but were free of cervical spine injury (n = 180). For children with sport and recreational activity-related cervical spine injuries, common injury patterns were subaxial (49%) and fractures (56%). These children were at increased odds of spinal cord injury without radiographic abnormalities compared with children with cervical spine injuries from other mechanisms (25% vs 6%). Children with sport and recreational activity-related trauma had increased odds of cervical spine injury if they had focal neurologic findings (odds ratio [OR], 5.7; 95% confidence interval [CI], 3.5-9.4), had complaints of neck pain (OR, 3.1; 95% CI, 1.9-5.0), were injured diving (OR, 43.5; 95% CI, 5.9-321.3), or sustained axial loading impacts (OR, 2.2; 95% CI, 1.3-3.5). Football (22%), diving (20%), and bicycle crashes (11%) were the leading activities associated with cervical spine injury. In children injured during sports and recreational activities, focal neurologic findings, neck pain, axial loading impacts, and the possibility of spinal cord injury without radiographic abnormality should guide the diagnostic evaluation for potential cervical spine injuries. Certain activities have a considerable frequency of cervical spine injury, which may benefit from activity-specific preventive measures.

In this exploratory study the authors investigated characteristics, including reported experiences of violence, related to incarcerated women's self-report of cervical cancer screening and cancer history and treatment. During a four month period in 2010, 204 women in Kansas City jails were surveyed. Multiple logistic regression models were used to examine the relations of socio-demographic and community characteristics and history of violence among the women to their cervical cancer screening, diagnosis, and treatment histories. Forty percent of the women in the current sample reported abnormal Pap histories, though only 6% of all Pap smears done in the U.S. are abnormal. Women who reported abuse histories in this study were found to be more likely to report having ever had an abnormal Pap smear (for physical abuse Odds Ratio [OR] = 6.05; CI 2.36, 15.54 and for past year intimate partner violence OR = 2.41; CI 1.09, 5.31). Participants who did not fear neighborhood violence were less likely to report an abnormal Pap history (OR = 0.57; CI 0.34, 0.96) and more likely to visit a family doctor for their Pap screenings (OR = 1.91; CI 1.01, 3.60). Women who perceived greater neighborhood violence had increased odds of reporting that they received Pap screenings in a hospital setting (OR = 1.47; CI 1.08, 2.00). Frequency of Pap screening did not differ in women who did and did not have fear of neighborhood violence. This study highlights the heightened cervical cancer risk experienced by women with criminal justice histories and suggests that violence at several levels has implications for cervical cancer prevention for these women.

High-risk human papillomaviruses (HR-HPV) infection has been associated with 90% of anal cancer cases. Women with abnormal cytology are a high-risk group to develop anal neoplasia. The aim of this study is to describe the prevalence and epidemiology of HR-HPV 16, 18, 45, and 58 anal infections in women with cervical abnormalities, as well as to assess E2 gene integrity. A cross-sectional study was performed on 311 cervical and 311 anal samples from patients with abnormal cytology in two colposcopy clinics in Yucatan, Mexico. A specific PCR for oncogenes was performed in order to identify HVP 16, 18, 45 and 58. Real time PCR was used to amplify the whole HPV 16, 18, and 58 E2 gene to verify its integrity in anal samples. High risk HPV 16, 18, 58, and/or 45 were found in 41.47% (129/311) of cervical samples, and in 30.8% (96/331) of anal samples, with 18% (57/311) of the patients being positive in both samples. The same genotypes in both anatomical sites were observed in 11.25% (35/311). The E2 gene was disrupted in 82% of all tested samples. The frequency of genome disruption viral integration in anal samples by genotype was: HPV 58 (97.2%); HPV 16 (72.4%), and HPV 18 (0%). Women with cervical disease have HR-HPV anal infections, and most of them have the E2 gene disrupted, which represents a risk to develop anal cancer.

The Pap stained cervical smear is a screening tool for cervical cancer. Commercial systems are used for automated screening of liquid based cervical smears. However, there is no image analysis software used for conventional cervical smears. The aim of this study was to develop and test the diagnostic accuracy of a software for analysis of conventional smears. The software was developed using Python programming language and open source libraries. It was standardized with images from Bethesda Interobserver Reproducibility Project. One hundred and thirty images from smears which were reported Negative for Intraepithelial Lesion or Malignancy (NILM), and 45 images where some abnormality has been reported, were collected from the archives of the hospital. The software was then tested on the images. The software was able to segregate images based on overall nuclear: cytoplasmic ratio, coefficient of variation (CV) in nuclear size, nuclear membrane irregularity, and clustering. 68.88% of abnormal images were flagged by the software, as well as 19.23% of NILM images. The major difficulties faced were segmentation of overlapping cell clusters and separation of neutrophils. The software shows potential as a screening tool for conventional cervical smears; however, further refinement in technique is required.

T-wave axis deviation (TDev) may help identifying subjects at risk for major cardiac events and mortality, but the pathogenesis of TDev is not well established; in particular, the possible association between TDev and inflammation is unexplored and unknown. We aimed at investigating the association between low-grade inflammation and TDev abnormalities by conducting a cross-sectional analysis on 17,507 subjects apparently free from coronary heart and haematological diseases enrolled in the MOLI-SANI study. TDev was measured from a standard 12-lead resting electrocardiogram. High sensitivity (Hs) C-reactive protein (CRP), leukocyte (WBC) and platelet counts, neutrophil or granulocyte to lymphocyte ratios were used as markers of inflammation. In multivariable model subjects reporting high CRP levels had higher odds of having borderline and abnormal TDev (OR=1.70; 95 %CI: 1.53-1.90 and OR=1.72; 95 %CI: 1.23-2.41, respectively); the association was still significant, although reduced, after controlling for body mass index (OR=1.17; 95 %CI: 1.05-1.32, for borderline and OR=1.46; 95 %CI: 1.03-2.08, for abnormal). Similarly, higher neutrophil or granulocyte to lymphocyte ratios were associated with increased odds of having abnormal TDev. Neither platelet nor leukocyte counts were associated with abnormal TDev. The relationship between CRP with TDev abnormalities was significantly stronger in men, in non- obese or normotensive individuals, and in those without metabolic syndrome. In conclusion, C-reactive protein and some cellular biomarkers of inflammation such as granulocyte or neutrophil to lymphocyte ratios were independently associated with abnormal TDev, especially in subjects at low CVD risk. These results suggest that a low-grade inflammation likely contributes to the pathogenesis of T- wave axis deviation.

Computer-assisted cervical cancer screening using neural networks.

PubMed

Mango, L J

1994-03-15

A practical and effective system for the computer-assisted screening of conventionally prepared cervical smears is presented and described. Recent developments in neural network technology have made computerized analysis of the complex cellular scenes found on Pap smears possible. The PAPNET Cytological Screening System uses neural networks to automatically analyze conventional smears by locating and recognizing potentially abnormal cells. It then displays images of these objects for review and final diagnosis by qualified cytologists. The results of the studies presented indicate that the PAPNET system could be a useful tool for both the screening and rescreening of cervical smears. In addition, the system has been shown to be sensitive to some types of abnormalities which have gone undetected during manual screening.

To investigate the risks of invasive cervical cancer after detection of atypical glandular cells (AGC) during cervical screening. Nationwide population based cohort study. Cancer and population registries in Sweden. 3,054,328 women living in Sweden at any time between 1 January 1980 and 1 July 2011 who had any record of cervical cytological testing at ages 23-59. Of these, 2,899,968 women had normal cytology results at the first screening record. The first recorded abnormal result was atypical glandular cells (AGC) in 14 625, high grade squamous intraepithelial lesion (HSIL) in 65 633, and low grade squamous intraepithelial lesions (LSIL) in 244 168. Cumulative incidence of invasive cervical cancer over 15.5 years; proportion of invasive cervical cancer within six months of abnormality (prevalence); crude incidence rates for invasive cervical cancer over 0.5-15.5 years of follow-up; incidence rate ratios compared with women with normal cytology, estimated with Poisson regression adjusted for age and stratified by histopathology of cancer; distribution of clinical assessment within six months after the abnormality. The prevalence of cervical cancer was 1.4% for women with AGC, which was lower than for women with HSIL (2.5%) but higher than for women with LSIL (0.2%); adenocarcinoma accounted for 73.2% of the prevalent cases associated with AGC. The incidence rate of invasive cervical cancer after AGC was significantly higher than for women with normal results on cytology for up to 15.5 years and higher than HSIL and LSIL for up to 6.5 years. The incidence rate of adenocarcinoma was 61 times higher than for women with normal results on cytology in the first screening round after AGC, and remained nine times higher for up to 15.5 years. Incidence and prevalence of invasive cervical cancer was highest when AGC was found at ages 30-39. Only 54% of women with AGC underwent histology assessment within six months, much less than after HSIL (86%). Among women with histology assessment within six months, the incidence rate of cervical cancer after AGC was significantly higher than that after HSIL for up to 6.5 years. AGC found at cervical screening is associated with a high and persistent risk of cervical cancer for up to 15 years, particularly for cervical adenocarcinoma and women with AGC at age 30-39. Compared with the reduction in risk of cancer seen after HSIL management, management of AGC seems to have been suboptimal in preventing cervical cancer. Research to optimise management is needed, and a more aggressive assessment strategy is warranted. Published by the BMJ Publishing Group Limited.

As with other mental disorders, the causes of borderline personality disorder (BPD) are complex and not fully understood. In this study we aimed to determine whether adults with BPD exhibit microstructural abnormalities using diffusion tensor imaging (DTI). 56 female right-handed individuals (age range, 14-18 years), 19 with a DSM-IV diagnosis of BPD, 18 patients with a DSM-IV defined current psychiatric disorder and 19 healthy control subjects were included. Groups were matched for age and IQ. DTI Images were analyzed using Tract-Based Spatial Statistics (TBSS). The analysis revealed significanty reduced fractional anisotropy (FA) values in the group of BPD patients compared to the normal controls. Similar FA reductions could not be found comparing BPD patients to clinical controls. Several clusters of increased radial (DR), axial (DA), and mean (MD) diffusivity were consistently identified when comparing the BPD patients to clinical as well as to healthy controls. None of the measures showed significant differences between the clinical and healthy controls. Diverse possible factors have been suggested to play a role in the disease, including environmental factors, neurobiological factors, or brain abnormalities. The presented results may play an important role in this ongoing debate.

To assess the association between peer relationship problems and childhood overweight and obesity. Data on 4718 preschool children were obtained at the obligatory school entry health examination in Bavaria. Parentally reported peer relationship problems ('normal', 'borderline' or 'abnormal') were assessed from the Strengths and Difficulties Questionnaire. Overweight and obesity were defined according to age- and gender-specific BMI cut-off points. Multivariate logistic regression analysis was performed to control potential confounders. The prevalence of overweight and obesity was higher among children with 'borderline' or 'abnormal' peer relationship problems compared to 'normal' children. The association of 'abnormal' peer relationship problems was still significant in the final logistic regression model for girls [odds ratio (OR) for overweight 2.0; 95% confidence interval (CI): 1.4-3.0; OR for obesity 2.6; 95% CI: 1.3-5.0]. Among boys the adjusted odds ratio were lower and no longer significant. The significantly increased prevalence of overweight and obesity among preschool children with peer relationship problems could not be explained by confounding. It seems evident that there is a relevant co-morbidity of peer relationship problems and obesity in pre-school children pointing to the need of interventions focusing on both physical as well as psychosocial health.

We investigated the association between bacterial vaginosis (BV) and human papillomavirus (HPV) infection in Papanicolaou smears in a Brazilian population. Cross-sectional analysis was performed on 673 samples collected from women attending public health centers in Olinda (PE, Brazil) by conventional cytology methodology and molecular analysis, PCR tests (GP5+/6+ and MY09/11). Cytological abnormalities, BV, and HPV-DNA were detected in 23 (3.4%) samples, 189 samples (28.1%), and 210 samples (31.2%), respectively. GP5+/6+ primers resulted in higher detection performance than MY09/11 primers, with 81% concordance between both primers (P < 0.0001). The occurrence of HPV-DNA and BV had ORs of 8.59 (P < 0.0001) and 2.91 (P = 0.0089) for abnormal cytology, respectively, whereas the concomitant presence of both infections showed an OR equal to 3.82 (P = 0.0054). Therefore, we observed an association between abnormal cervical cytology and HPV infection, BV, or both HPV infection and BV. These results highlight the necessity of monitoring patients presenting not only HPV, but also BV, as risk factors for cervical lesion development.

A retrospective study of 910 patients surviving at least five years after cervical irradiation for Hodgkin's disease, non-Hodgkin's lymphoma, or primary head an neck neoplasms showed the incidence of stroke following cervical irradiation was 63 of 910 patients (6.3%) during a mean period of observation of nine years. This represents a trend toward an increased risk for this population observed over the same period of time (p = 0.39). A prospective study of 118 similar patients currently living five years after cervical radiotherapy was performed to determine the incidence of carotid artery disease occurring as a consequence of neck irradiation. Abnormal carotid phonangiograms (CPA) were found in 25% of the patients and abnormal oculoplethysmographs (OPG) were found in 17%. These studies represent significant carotid lesions that are not expected in such a population. It is concluded that the carotid stenoses demonstrated are most likely a consequence of prior irradiation. Patients that are five-year survivors of cervical irradiation should have noninvasive vascular laboratory studies performed as part of their routine follow-up examinations in order to detect these carotid lesions while they are occult.

Invasive cervical cancer is today the fourth most common cancer of women in western civilization. Screening programs have led to a continuously decrease. Nevertheless, both screening and a positive test result are known to be associated with a negative psychological impact. Screening programs in European countries differ and thus psychological impact might as well. The aim of this study was to evaluate the psychological impact of women with an abnormal Pap smear in a German cohort. Between July 2013 and May 2014, a self-assessment questionnaire was distributed to 595 patients that were referred to a special clinic for cervical dysplasia for further evaluation of an abnormal Pap smear. Patients were recruited in five different centers. Most patients (45.9 %) were informed about the test result via phone call by their doctor. 68.8 % of the patients felt anxious and 26.3 % even felt panic. After having talked to their physician, 51.4 % of our cohort still felt worried and only 24.4 % felt reassured. Concerning disease management, 48.4 % underwent a control Pap smear in 6 months. The preferred information source was the physician (63.9 %). Compared to the results in other European countries, our study cohort showed differences concerning age distribution, patients living in a partnership, number of children and especially disease management. Cancer screening itself and abnormal test results have an impact on patient's feelings. To reduce the psychological impact, patients need to be better informed about the risks and benefits of cancer screening programs and in case of cervical cancer screening about the meaning of an abnormal test result. Our results underline the importance of a trustful physician-patient relationship in that matter.

Sports activity has become extremely popular among amateurs. Electrocardiography is a useful tool in screening for cardiac pathologies in athletes; however, there is little data on electrocardiographic abnormalities in the group of amateur athletes. The aim of this study was to analyze the abnormalities in resting and exercise electrocardiograms (ECGs) in a group of amateur athletes, and try to determine whether the criteria applied for the general population or for athletes' ECGs should be implemented in this group. In 40 amateur male marathon runners, 3 consecutive 12-lead ECGs were performed: 2-3 weeks before (stage 1), just after the run (stage 2) and 2-3 weeks after the marathon (stage 3). Resting (stage 1) and exercise (stage 2) ECGs were analyzed following the refined criteria for the assessment of athlete's ECG (changes classified as training-related, borderline or training-unrelated). In resting ECGs, at least 1 abnormality was found in 92.5% of the subjects and the most common was sinus bradycardia (62.5%). In post-exercise ECGs, at least 1 abnormality was present in 77.5% of the subjects and the most common was right atrium enlargement (RAE) (42.5%). Training-related ECG variants were more frequent at rest (82.5% vs 42.5%; p = 0.0008), while borderline variants - after the run (22.5% vs 57.5%; p = 0.0004). Training-unrelated abnormalities were found in 15% and 10% of the subjects, respectively (p-value - nonsignificant), and the most common was T-wave inversion. Even if the refined criteria rather than the criteria used for normal sedentary population were applied, the vast majority of amateur runners showed at least 1 abnormality in resting ECGs, which were mainly training-related variants. However, at rest, in 15% of the subjects, pathologic training-unrelated abnormalities were found. The most frequent post-exercise abnormality was right atrial enlargement. General electrocardiographic screening in amateur athletes should be taken into consideration.

Abnormal pelvic morphology and high cervical length are responsible for high-risk pregnancies in women displaying achondroplasia.

Pregnancies of women displaying achondroplasia are at high risk of adverse events. Early sonographic assessment of affected women can indicate an unusually long cervical length. It is the consequence of pathological anatomy of the pelvis. Thus, there is a foreseeable dystocia owing to cephalopelvic disproportion. Furthermore, this situation could also complicate cervical ripening prior to fetal extraction.

A decrease in diastolic blood pressure (DBP) with exercise is considered normal, but the significance of an increase in DBP has not been validated. Our aim was to determine the relationship of DBP increasing on a stress test regarding comorbidities and mortality. Our database was reviewed from 1993-2010 using the first stress test of a patient. Non-Minnesota residence, baseline CV disease, rest DBP <60 or >100 mmHg, and age <30 or ≥80 were exclusion criteria. DBP response was classified Normal if peak DBP-rest DBP <0, Borderline 0-9, Abnormal ≥10mmHg. Mortality was determined from Mayo Clinic records and Minnesota Death Index. Logistic regression was used to determine the relationship of DBP response to presence of comorbidities. Cox regression was used to determine total and CV mortality risk by DBP response. All analyses were adjusted for age, sex and resting DBP. 20760 patients were included (51±11 years, female n=7314). Rest/peak averaged DBP 82±8/69 ±15 mmHg in normal vs 79±9/82±9 mmHg in borderline vs 76±9/92±11 mmHg in abnormal DBP response. There were 1582 deaths (8%) with 557 (3%) CV deaths over 12±5 years of follow-up. In patients with borderline and abnormal DBP response, odds ratios for obesity, hypertension, diabetes and current smoking were significant, while hazard ratios for total and CV death were not significant compared to patients with normal DBP response. DBP response to exercise is significantly associated with important comorbidities at the time of the stress test but does not add to the prognostic yield of stress test.

Phosphorylated α-synuclein (p-syn) in skin nerves mainly in the proximal sites is a promising neurodegenerative biomarker for idiopathic Parkinson disease (IPD). However, the p-syn spine distribution particularly in patients with unilateral motor dysfunctions remains undefined. This study aimed to investigate in IPD p-syn differences between left and right cervical spine sites in patients with prevalent unilateral motor symptoms, and cervical and thoracic spine sites in patients with bilateral motor symptoms. We enrolled 28 IPD patients fulfilling clinical diagnostic criteria associated with abnormal nigro-striatal DatScan and cardiac MIBG: 15 with prevalently unilateral motor symptoms demonstrated by DatScan; 13 with bilateral motor symptoms and DatScan abnormalities. Patients underwent skin biopsy searching for intraneural p-syn deposits: skin samples were taken from C7 paravertebral left and right sites in unilateral patients and from cervical (C7) and thoracic (Th12) paravertebral spine regions in bilateral patients. Unilateral patients displayed 20% of abnormal p-syn deposits in the affected motor site, 60% in both sites and 20% only in the non-affected site. P-syn was found in all patients in C7 but in only 62% of patients in Th12. Our data showed that cervical p-syn deposits displayed a uniform distribution between both sides not following the motor dysfunction in unilateral patients, and skin nerve p-syn deposits demonstrated a spine gradient with the cervical site expressing the highest positivity. © 2017 American Association of Neuropathologists, Inc.

Background: Female immigration in Catalonia, Spain, increased dramatically in the last 10 years. The Public Health system in the Region, provides a free of charge opportunistic cervical cancer screening. Aim: This study examines cervical cancer screening coverage and prevalence of cytology abnormalities in Catalonia by immigration status. Methods: The study analyzes the cytologies registered among women aged 25–65 that have been attended at the Primary Health Centers (PHC) for any reason (n = 1,242,230) during 2008–2011. Coverage was estimated from Governmental data base Information System Primary Care (SISAP) that includes 77% of PHC. The database is anonymous, and includes information on age, country of birth, diagnostic center, and cytology results. Results: During the period 2008–2011, 642,643 smears were performed in a total of 506,189 women over 14 years, of whom 18.3% were immigrants. Cytology coverage was higher among immigrant women compared to Spanish born (51.2 and 39% respectively). Immigrant women also had a higher prevalence of abnormal Paps compared to the Spanish population, 4.5 and 2.9% respectively (p < 0.001). Conclusion: Immigrant women in Catalonia had a high access to the Public Health Services and to cervical cancer screening facilities. The higher prevalence of abnormal cytologies in immigrant women compared to native women indicates the relevance to prioritize cervical cancer screening activities on a regular base in new comers.

Although cervical spine CT (CSCT) accurately detects bony injuries, it may not identify all soft tissue injuries. Although some clinicians rely exclusively on a negative CT to remove spine precautions in unevaluable patients or patients with cervicalgia, others use MRI for that purpose. The objective of this study was to determine the rates of abnormal MRI after a negative CSCT. Blunt trauma patients who either were unevaluable or had persistent midline cervicalgia and underwent an MRI of the C-spine after a negative CSCT were enrolled prospectively in eight Level I and II New England trauma centers. Demographics, injury patterns, CT and MRI results, and any changes in cervical spine management as a result of MRI imaging were recorded. A total of 767 patients had MRI because of cervicalgia (43.0%), inability to evaluate (44.1%), or both (9.4%). MRI was abnormal in 23.6% of all patients, including ligamentous injury (16.6%), soft tissue swelling (4.3%), vertebral disc injury (1.4%), and dural hematomas (1.3%). Rates of abnormal neurological signs or symptoms were not different among patients with normal versus abnormal MRI. (15.2 vs. 18.8%, p = 0.25). The c-collar was removed in 88.1% of patients with normal MRI and 13.3% of patients with an abnormal MRI. No patient required halo placement, but 11 patients underwent cervical spine surgery after the MRI results. Six of the eleven had neurological signs or symptoms. In a select population of patients, MRI identified additional injuries in 23.6% of patients despite a normal CSCT. It is uncertain if this is a true limitation of CT technology or represents subtle injuries missed in the interpretation of the scan. The clinical significance of these abnormal MRI findings cannot be determined from this study group. Therapeutic study, level IV.

Vaccination against the most common oncogenic human papillomavirus (HPV) types, HPV-16 and HPV-18, could prevent development of up to 70% of cervical cancers worldwide. We did a randomised, double-blind, controlled trial to assess the efficacy, safety, and immunogenicity of a bivalent HPV-16/18 L1 virus-like particle vaccine for the prevention of incident and persistent infection with these two virus types, associated cervical cytological abnormalities, and precancerous lesions. We randomised 1113 women between 15-25 years of age to receive three doses of either the vaccine formulated with AS04 adjuvant or placebo on a 0 month, 1 month, and 6 month schedule in North America and Brazil. Women were assessed for HPV infection by cervical cytology and self-obtained cervicovaginal samples for up to 27 months, and for vaccine safety and immunogenicity. In the according-to-protocol analyses, vaccine efficacy was 91.6% (95% CI 64.5-98.0) against incident infection and 100% against persistent infection (47.0-100) with HPV-16/18. In the intention-to-treat analyses, vaccine efficacy was 95.1% (63.5-99.3) against persistent cervical infection with HPV-16/18 and 92.9% (70.0-98.3) against cytological abnormalities associated with HPV-16/18 infection. The vaccine was generally safe, well tolerated, and highly immunogenic. The bivalent HPV vaccine was efficacious in prevention of incident and persistent cervical infections with HPV-16 and HPV-18, and associated cytological abnormalities and lesions. Vaccination against such infections could substantially reduce incidence of cervical cancer.

State-of-the-art cervical cancer prevention includes human papillomavirus (HPV) vaccination among adolescents and screening/treatment of cervical precancer (CIN3/AIS and, less strictly, CIN2) among adults. HPV testing provides sensitive detection of precancer but, to reduce overtreatment, secondary "triage" is needed to predict women at highest risk. Those with the highest-risk HPV types or abnormal cytology are commonly referred to colposcopy; however, expert cytology services are critically lacking in many regions. To permit completely automatable cervical screening/triage, we designed and validated a novel triage method, a cytologic risk score algorithm based on computer-scanned liquid-based slide features (FocalPoint, BD, Burlington, NC). We compared it with abnormal cytology in predicting precancer among 1839 women testing HPV positive (HC2, Qiagen, Germantown, MD) in 2010 at Kaiser Permanente Northern California (KPNC). Precancer outcomes were ascertained by record linkage. As additional validation, we compared the algorithm prospectively with cytology results among 243 807 women screened at KPNC (2016-2017). All statistical tests were two-sided. Among HPV-positive women, the algorithm matched the triage performance of abnormal cytology. Combined with HPV16/18/45 typing (Onclarity, BD, Sparks, MD), the automatable strategy referred 91.7% of HPV-positive CIN3/AIS cases to immediate colposcopy while deferring 38.4% of all HPV-positive women to one-year retesting (compared with 89.1% and 37.4%, respectively, for typing and cytology triage). In the 2016-2017 validation, the predicted risk scores strongly correlated with cytology (P < .001). High-quality cervical screening and triage performance is achievable using this completely automated approach. Automated technology could permit extension of high-quality cervical screening/triage coverage to currently underserved regions.

To compare prevalence of anxiety in women with abnormal cervical cytology (Pap) undergoing colposcopy to that of women attending the outpatient clinic for check-up and to examine predicting factors. In this cross-sectional analytical study, 100 women with abnormal cervical cytology (abnormal Pap group) and 100 women who attended our outpatient clinic for check-up (control group) were recruited from June 2013 to January 2014. The Hospital Anxiety and Depression Scale (HADS) was employed to determine anxiety in the participants with the score of ≥ 11 suggestive of clinically significant anxiety. The prevalence of anxiety and the mean HADS scores for anxiety were compared between the groups. For those with abnormal Pap, association between clinical factors and anxiety was assessed. A p-value of < 0.05 was considered significant. Median age was different between the groups, 44.0 years in the abnormal Pap group and 50.0 years in the control group (p=0.01). The proportion of participants who had more than one sexual partner was higher in the abnormal Pap group, 39.2% vs. 24.7% (p=0.03) and the prevalence of anxiety was significantly higher 14/100 (14.0%) vs. 3/100 (3.0%) (p < 0.01). The prevalence of depression was comparable between the groups. The mean HADS scores for anxiety and depression subscales were significantly higher in the abnormal Pap group, 6.6 vs. 4.8 (P < 0.01) and 3.9 vs. 3.1 (p=0.05), respectively. For the abnormal Pap group, no definite association between clinical factors and anxiety was demonstrated. The prevalence of anxiety in women with abnormal Pap awaiting colposcopy was significantly higher than that of normal controls. Special attention including thorough counselling, with use of information leaflets and psychological support, should be directed to these women.

To analyse the effect of the expert end-point committee (EPC) review on histological endpoint classification of cervical intraepithelial neoplasia (CIN). A cohort of women living with HIV were recruited in Burkina Faso (BF) and South Africa (SA) and followed over 18 months. Four-quadrant cervical biopsies were obtained in women with abnormalities detected by at least one screening test. A central review by a panel of five pathologists was organised at baseline and at endline. At baseline the prevalence of high-grade CIN (CIN2+) was 5.1% (28/554) in BF and 23.3% (134/574) in SA by local diagnosis, and 5.8% (32/554) in BF and 22.5% (129/574) in SA by the EPC. At endline the prevalence of CIN2+ was 2.3% (11/483) in BF and 9.4% (47/501) in SA by local diagnosis, and 1.4% (7/483) in BF and 10.2% (51/501) in SA by EPC. The prevalence of borderline CIN1/2 cases was 2.8% (32/1128) and 0.8% (8/984) at baseline and endline. Overall agreement between local diagnosis and final diagnosis for distinguishing CIN2+ from ≤CIN1 was 91.2% (κ=0.82) and 88.9% (κ=0.71) for BF at baseline and endline, and 92.7% (κ=0.79) and 98.7% (κ=0.97) for SA at baseline and endline. Among the CIN1/2 cases, 12 (37.5%) were graded up to CIN2 and 20 (62.5%) were graded down to CIN1 at baseline, and 3 (37.5%) were graded up to CIN2 and 5 (62.5%) were graded down to CIN1 at endline.

Oncogenic human papillomaviruses (HPVs) are the etiological agents of cervical cancer. Different cofactors might be needed for malignant transformation, but they still remain elusive. To delineate the role of Chlamydia trachomatis (CT) and herpes simplex virus type 2 (HSV2) in HPV-positive cervical intraepithelial neoplasia (CIN) lesions and cervical carcinoma a series of 149 cervical cancer and CIN biopsies were analyzed for CT and HSV2 DNA by PCR, and HPV genotyped by InnoLipa. Monitoring of aberrations in key intracellular pathways due to CT/HSV2 and HPV co-expression were analyzed with 13 biomarkers. Of the 149 samples tested, 136 were HPV DNA positive; 32/136 contained also CT DNA and 29 HSV2 DNA. Detection of CT was significantly (p = 0.0001) related to multiple-type HPV infections, while HSV2 was of borderline significance (p = 0.053). Of the 13 biomarkers tested, cytoplasmic and nuclear NF-kappaB and VEGF-C were significantly increased in CT+/HPV+ lesions; p = 0.023, p = 0.045, and p = 0.020 as well as survivin, p = 0.026. Survivin was the only marker that was overexpressed also in HSV2+/HPV+ lesions, p = 0.027. CT infection favors the entry and persistence of multiple HR-HPV types, which leads to viral integration, inhibition of apoptosis, overexpression of E6/E7 oncogenes and cell transformation.

High-risk human papillomavirus (HR-HPV) causes nearly 100% of cervical carcinoma. However, it remains unclear whether HPV can establish a latent infection, one which may be responsible for the second peak in incidence of cervical carcinoma seen in older women. Therefore, using Ventana in situ hybridisation (ISH), quantitative PCR assays and biomarkers of productive and transforming viral infection, we set out to provide the first robust estimate of the prevalence and characteristics of HPV genomes in FFPE tissue from the cervices of 99 women undergoing hysterectomy for reasons unrelated to epithelial abnormality. Our ISH assay detected HR-HPV in 42% of our study population. The majority of ISH positive samples also tested HPV16 positive using sensitive PCR based assays and were more likely to have a history of preceding cytological abnormality. Analysis of subsets of this population revealed HR-HPV to be transcriptionally inactive as there was no evidence of a productive or transforming infection. Critically, the E2 gene was always disrupted in those HPV16 positive cases which were assessed. These findings point to a reservoir of transcriptionally silent, disrupted HPV16 DNA in morphologically normal cervices, re-expression of which could explain the increase in incidence of cervical cancer observed in later life.

The aim of this study was to examine the association between CD4 count, human papilloma virus (HPV) infection, and the risk of cervical intraepithelial neoplasia among HIV-infected women. A cross-sectional study was conducted among 104 HIV-infected women attending an antiretroviral therapy clinic. They underwent Pap smear and cervical HPV DNA testing. The overall prevalence of HPV infection was 57.7%. HPV 16 was the commonest genotype found (38.5%); HPV 16 and 18 put together contributed to 73.3% of HPV infection; 27.5% of HIV-infected women had squamous cell abnormalities. Cervical intraepithelial neoplasia was less likely among women with CD4 count > 500/mm 3 (12%) and in those without opportunistic infections (17.8%). The prevalence of high-risk HPV infection was higher in women with high-grade squamous intraepithelial lesions or greater lesions (85.7%) as compared to women with normal cytology (52.1%). The high prevalence of HPV infection and cervical intraepithelial neoplasia in HIV-infected women warrants the need for regular Pap smear screening in these women and routine HPV vaccination for adolescents to reduce the burden of cervical cancer in India. © 2016 Japan Society of Obstetrics and Gynecology.

Liquid-based cytology (LBC) for cervical screening would benefit from laboratory practice guidelines that define specimen adequacy for reporting of slides. The evidence base required to define cell adequacy should incorporate both ThinPrep™ (TP; Hologic, Inc., Bedford, MA, USA) and SurePath™ (SP; BD Diagnostics, Burlington, NC, USA), the two LBC systems used in the UK cervical screening programmes. The objectives of this study were to determine (1) current practice for reporting LBC in England, Wales and Scotland, (2) a reproducible method for cell counting, (3) the cellularity of slides classified as inadequate, negative or abnormal and (4) the impact of varying cellularity on the likelihood of detecting cytological abnormalities. The study involved four separate arms to pursue each of the four objectives. (1) A questionnaire survey of laboratories was conducted. (2) A standard counting protocol was developed and used by three experienced cytopathologists to determine a reliable and reproducible cell counting method. (3) Slide sets which included a range of cytological abnormalities were each sent to three laboratories for cell counting to study the correlation between cell counts and reported cytological outcomes. (4) Dilution of LBC samples by fluid only (unmixed) or by dilution with a sample containing normal cells (mixed) was performed to study the impact on reporting of reducing either the total cell count or the relative proportion of abnormal to normal cells. The study was conducted within the cervical screening programmes in England, Wales and Scotland, using routinely obtained cervical screening samples, and in 56 participating NHS cervical cytology laboratories. The study involved only routinely obtained cervical screening samples. There was no clinical intervention. The main outcome measures were (1) reliability of counting method, (2) correlation of reported cytology grades with cellularity and (3) levels of detection of abnormal cells in progressively diluted cervical samples. Laboratory practice varied in terms of threshold of cellular adequacy and of morphological markers of adequacy. While SP laboratories generally used a minimum acceptable cell count (MACC) of 15,000, the MACC employed by TP laboratories varied between 5000 and 15,000. The cell counting study showed that a standard protocol achieved moderate to strong inter-rater reproducibility. Analysis of slide reporting from laboratories revealed that a large proportion of the samples reported as inadequate had cell counts above a threshold of 15,000 for SP, and 5000 and 10,000 for TP. Inter-rater unanimity was greater among more cellular preparations. Dilution studies demonstrated greater detection of abnormalities in slides with counts above the MACC and among slides with more than 25 dyskaryotic cells. Variation in laboratory practice demonstrates a requirement for evidence-based standards for designating a MACC. This study has indicated that a MACC of 15,000 and 5000 for SP and TP, respectively, achieves a balance in terms of maintaining sensitivity and low inadequacy rates. The findings of this study should inform the development of laboratory practice guidelines. The National Institute for Health Research Health Technology Assessment programme.

Objective: To study the clinical management way for HPV(+)/papanicolaou (Pap)(-) during cervical cancer screening. Methods: To analyze retrospectively the data from the patients who had loop electrical excision procedure (LEEP) for biopsy confirmed cervical intraepithelial neoplasia (CIN) Ⅱ in Peking University People's Hospital from Jan. 2010 to Dec. 2014. Results: (1) For biopsy confirmed CIN Ⅱ, HPV positive rate was 98.5% (135/137), Pap test positive [≥atypical squamous cell of undetermined significance (ASCUS)] rate was 69.3% (95/137), there was significant difference between them (χ(2)=43.32, P< 0.01). (2) For the 42 patients with HPV(+)/Pap(-), whose cytology slides were reviewed again. Among them, the interpretations of there were 16 cases confirmed as the same before, while 26 cases were changed to abnormal (≥ASCUS). Cytology be misdiagnosed was 19.0% (26/137) at the first review. Among the 26 cases, 13 (50.0%) cases were missed for the little amount of abnormal cells, 8 (30.8%) cases for mild atypical morphology changed; the other 5 (19.2%) cases missed for stain problems. (3) For the cervical LEEP samples, 37 cases of the pathology diagnosis were upgrade to CIN Ⅲ(+), among them, 2 cases of microinvasive cervical carcinoma, 1 case of invasive cancer, 34 cases of CIN Ⅲ; 37 cases were CINⅠ or no lesion found; 63 cases were still CIN Ⅱ. Four to six months later after LEEP, the cytology abnormal rate was 11.7% (16/137), and the HR-HPV positive rate was 34.3% (47/137). Conclusions: Compared with cytology alone, cytology combined with HPV testing increase the sensitivity of cervical high grade lesion. For the cases of HPV(+)/Pap(-) cases, the cytology slides should be reviewed. The quality control of cervical exfoliate sample collection and interpretation should be strengthened. LEEP procedure is not only a treatment method, but also it could provide samples to confirm the diagnosis.

The aims of this study was to determine proportion of HIV infected women with cervical pre-malignant lesions; and compare the use of Visual Inspection of the cervix after application of Acetic acid (VIA) and Papanicolau (Pap) smear in screening for cervical premalignant lesions in HIV positive women attending Care and Treatment Centre (CTC) at Muhimbili National Hospital (MNH), Dar es Salaam, Tanzania. A total of 316 women aged 18-70 years had a Pap smear taken for cytology, followed by spraying onto the cervix with 4% acetic acid and then inspecting it. Cytology was considered negative when there was no Cervical Intraepithelial Neoplasia (CIN) lesion reported from the Pap smear taken, and positive if CIN lesion 1, 2 or 3 was reported. Detection of a well-defined, opaque acetowhite lesion close to the squamocolumnar junction or close to the external cervical os constituted a positive VIA. Out of 316 women, 132 women had acetowhite lesions on VIA, making the proportion of abnormal cervical lesions to be 42.4%. One hundred and one out of 312 women (32.4%) had CIN lesions detected on Pap smear. The proportion of agreement between these two tests was 0.3. The proportion of agreement was moderate in women with advanced WHO HIV clinical stage of the disease and in women not on ART (Anti Retroviral Therapy). Women with CD-4 count less than 200 cells/mm3 had more abnormal cervical lesions. There is considerable proportion of HIV positive women with premalignant lesions of the cervix. Considering the proportion of HIV women with abnormal lesions and the difficulty in logistics of doing Pap smear in low resource settings, these results supports the recommendation to introduce screening of premalignant lesions of the cervix using VIA to all HIV infected women.

The link between high-risk human Papillomavirus (HR-HPV) and other sexually transmitted diseases (STDs) in the risk of developing cervical cancer still unclear. Thus, in this report we investigated the rates of co-infections between HPV and other important non-HPV STDs in different cervical findings using a multiplex polymerase chain reaction (M-PCR) to simultaneously detect Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, Trichomonas vaginalis, HSV-1 and -2, and Treponema pallidum. A total of 838 women aged 18 to 68 years were screened using Papanicolaou smears for cervical abnormalities, HPV and non-HPV STDs using PCR and M-PCR methods. A total of 614 (73.3%) of the women had normal cytology (NILM) and 224 (26.7%) women exhibited abnormal cytology (≥ ASC-US). HPV-DNA prevalence was 33.9%, and HPV-16 was the most prevalent genotype in women with NILM and ≥ ASC-US cytology. Non-HPV STDs were detected in 30.4% women and T. vaginalis was the most prevalent one (11.6%). A higher increased risk of ≥ ASC-US and HSIL occurred in co-infections of HR-HPV with C. trachomatis and N. gonorrhoeae. Co-infections of HPV-DNA and HR-HPV with HSV-2 exhibited a similar increased risk but only with ≥ ASC-US. Co-infections of HPV-DNA and HR-HPV with T. vaginalis demonstrated a similar increased risk of ≥ ASC-US and HSIL. We found that C. trachomatis and N. gonorrhoeae were the primary pathogens associated with HR-HPV for the increased risk for all grades of cervical abnormalities but mainly for HSIL, suggesting a possible synergistic action in cervical lesions progression. Our results reinforce the hypothesis that some non-HPV STDs might play a role as co-factors in HPV-mediated cervical carcinogenesis. These data improve our understanding of the etiology of SCC and may also be useful for disease prevention. PMID:27429850

Studies of epilepsy associated with chromosomal abnormalities may provide information about clinical and EEG phenotypes and possibly to identify new epilepsy genes. We describe a female patient with intractable focal epilepsy, borderline intellectual functioning, and facial dysmorphisms, in whom genetic study (i.e., karyotype and array-CGH analysis) revealed a distal trisomy 4p and distal monosomy Xq. Although any genetic hypothesis remains speculative, several genes are located in the 4p chromosome segment involved in the rearrangement, some of which may be related to epilepsy.

Background & objectives: India has the third highest burden of HIV and highest number of cervical cancer in the world. A cross-sectional study was performed to determine the prevalence and types of human papillomavirus (HPV) infection, and the factors associated with HPV infection and abnormal cervical cytology in HIV-positive women attending the Antiretroviral Therapy (ART) Centre in a tertiary care hospital in eastern India. Methods: We screened 216 HIV- positive women with Papanicolau smear cytology and HPV testing. HPV DNA was detected by using consensus primers followed by sequencing. Results: Of the 216 HIV-positive women screened, 58 (26.85%) were HPV-positive; 56 (25.9%) were of high-risk (HR) HPV type. The most prevalent HPV type was HPV-16 (7.9%); non 16 and 18 HPV types were present in 17.6 per cent patients. Age ≤ 35 yr [(OR), 2.56 (1.26-5.19)], illiteracy [OR, 2.30 (1.19-4.46)], rural residence [OR, 3.99 (1.27-12.56)] and CD4 ≤350/μl [OR, 2.46 (1.26-4.83)] were associated with increased risk of acquisition of HPV. One hundred thirty nine (74.33%) patients had normal/ negative for intraepithelial lesions (NILM) cytology, three (1.60%) had atypical squamous cells of undetermined significance (ASCUS), 32 (17.11%) had low-grade squamous intraepithelial lesions (LSIL), 10 (5.35%) had high-grade squamous intraepithelial lesions (HSIL) and three (1.60%) had carcinoma cervix. WHO clinical Stage III and IV [OR, 2.83 (1.07-7.49)] and CD4 ≤350/μl [OR, 2.84 (1.30-6.20)] were risk factors for abnormal cytology. Interpretation &conclusions: Our study showed 26.85 per cent HPV positivity in HIV infected women in this region, with HPV-16 as the commonest genotype. Abnormal cervical cytology was seen in about 25 per cent women. Regular Pap smear screening as recommended by the National AIDS Control Organization will help in early detection of cervical abnormalities in HIV- positive women. PMID:26997018

Osseous malformations in the skull and cervical vertebrae of lions in captivity are believed to be caused by hypovitaminosis A. These often lead to severe neurologic abnormalities and may result in death. We describe the characterization of these abnormalities based on computed tomography (CT). CT images of two affected and three healthy lions were compared with define the normal anatomy of the skull and cervical vertebrae and provide information regarding the aforementioned osseous malformations. Because bone structure is influenced by various factors other than the aforementioned disease, all values were divided by the skull width that was not affected. The calculated ratios were compared and the most pronounced abnormalities in the affected lions were, narrowing of the foramen magnum, thickening of the tentorium osseus cerebelli and thickening of the dorsal arch of the atlas. CT is useful for detection of the calvarial abnormalities in lions and may be useful in further defining this syndrome.

To assess differences in fetal behavior in both normal fetuses and fetuses with cerebral ventriculomegaly (VM). In a period of eighteen months, in a longitudinal prospective cohort study, Kurjak Antenatal NeuorogicalTest (KANET) was applied to assess fetal behavior in both normal pregnancies and pregnancies with cerebral VM using four-dimensional ultrasound (4D US). According to the degree of enlargement of the ventricles, VM was divided into three groups: mild, moderate and severe. Moreover fetuses with isolated VM were separated from those with additional abnormalities. According to the KANET, fetuses with scores ≥ 14 were considered normal, those with scores 6-13 borderline and abnormal if the score was ≤ 5. Differences between two groups were examined by Fisher's exact test. Differences within the subgroups were examined by Kruskal-Wallis test and contingency table test. KANET scores in normal pregnancies and pregnancies with VM showed statistically significant differences. Most of the abnormal KANET scores as well as most of the borderline-scores were found among the fetuses with severe VM associated with additional abnormalities. There were no statistically significant differences between the control group and the groups with isolated and mild and /or moderate VM. Evaluation of the fetal behavior in fetuses with cerebral VM using KANET test has the potential to detect fetuses with abnormal behavior, and to add the dimension of CNS function to the morphological criteria of VM. Long-term postnatal neurodevelopmental follow-up should confirm the data from prenatal investigation of fetal behavior.

Cervical cancer is one of the major causes of deaths due to cancer among women in India. Pap smear is one of the best methods to detect early changes in cervix. However, there is lack of data on awareness level of women about Pap smear and various risk factors for cervical cancer. To study the awareness about various risk factors for cervical cancer, health-seeking behavior and hygienic practices among women and to assess the distress experienced by these women before the Pap smear examination. This cross-sectional study was carried out on women coming for a Pap smear examination in a tertiary teaching hospital in New Delhi. A pretested interview schedule was used to get information after obtaining their informed consent. Fifty-seven percent stated that they did not consult a doctor when they noticed the symptoms the first time. Sixty-one percent did not know what a cervical cancer is and a same percentage of women did not know what a Pap smear examination was. Older age group, Muslim and literate women had higher number of abnormal Pap smear results. Women who reported being stressed in their lives had higher number of abnormal smears as compared to women who claimed to lead a stress free life. Poor hygienic practices among these women from urban areas were also associated with abnormal Pap smear results. The study concluded that factors such as poor awareness, shyness, poor hygiene, and old age could be responsible for abnormal Pap smears and this needs special attention in cancer prevention activities of the government.

Background We evaluated the efficacy of a Chicago-based cancer patient navigation program developed to increase the proportion of patients reaching diagnostic resolution and reduce the time from abnormal screening test to definitive diagnostic resolution. Methods Women with an abnormal breast (n=352) or cervical (n=545) cancer screening test were recruited for the quasi-experimental study. Navigation subjects originated from five federally qualified health center sites and one safety net hospital. Records-based concurrent control subjects were selected from 20 sites. Control sites had similar characteristics to the navigated sites in terms of patient volume, racial/ethnic composition, and payor mix. Mixed-effects logistic regression and Cox proportional hazard regression analyses were conducted to compare navigation and control patients reaching diagnostic resolution by 60 days and time to resolution, adjusting for demographic covariates and site. Results Compared to controls, the breast navigation group had shorter time to diagnostic resolution (aHR=1.65, CI=1.20–2.28) and the cervical navigation group had shorter time to diagnostic resolution for those who resolved after 30 days (aHR= 2.31, CI=1.75–3.06), with no difference before 30 days (aHR= 1.42, CI=0.83–2.43). Variables significantly associated with longer time to resolution for breast cancer screening abnormalities were being older, never partnered, abnormal mammogram and BI-RADS 3, and being younger and Black for cervical abnormalities. Conclusions Patient navigation reduces time from abnormal cancer finding to definitive diagnosis in underserved women. Impact Results support efforts to use patient navigation as a strategy to reduce cancer disparities among socioeconomically disadvantaged women. PMID:23045544

To our knowledge there are only 15 reported cases of pneumatocysts in the cervical spine, but awareness of their existence should help the clinician when diagnosing abnormalities in radiological images. When faced with intravertebral gas, in addition to considering more sinister causes, one should consider the differentials including pneumatocysts. Despite our relative lack of understanding of these benign lesions the knowledge that they can change over time should prevent unnecessary testing or treating. We present a patient who fell down stairs and was found to have cervical intravertebral gas, on computed tomography imaging, with the typical appearance of a pneumatocyst. PMID:26719615

The DuPage Patient Navigation Collaborative evaluated the Patient Navigation Research Program (PNRP) model for uninsured women receiving free breast or cervical cancer screening through the Illinois Breast and Cervical Cancer Program in DuPage County, Illinois. We used medical records review and patient surveys of 477 women to compare median follow-up times with external Illinois Breast and Cervical Cancer Program and Chicago PNRP benchmarks of performance. We examined the extent to which we mitigated community-defined timeliness risk factors for delayed follow-up, with a focus on Spanish-speaking participants. Median follow-up time (29.0 days for breast and 56.5 days for cervical screening abnormalities) compared favorably to external benchmarks. Spanish-speaking patients had lower health literacy, lower patient activation, and more health care system distrust than did English-speaking patients, but despite the prevalence of timeliness risk factors, we observed no differences in likelihood of delayed (> 60 days) follow-up by language. Our successful replication and scaling of the PNRP navigation model to DuPage County illustrates a promising approach for future navigator research.

Instability of affects and interpersonal relations are important features of borderline personality disorder (BPD). Interpersonal problems of individuals suffering from BPD might develop based on abnormalities in the processing of facial affects and high sensitivity to negative affective expressions. The aims of the present study were to examine automatic evaluative shifts and latencies as a function of masked facial affects in patients with BPD compared to healthy individuals. As BPD comorbidity rates for mental and personality disorders are high, we investigated also the relationships of affective processing characteristics with specific borderline symptoms and comorbidity. Twenty-nine women with BPD and 38 healthy women participated in the study. The majority of patients suffered from additional Axis I disorders and/or additional personality disorders. In the priming experiment, angry, happy, neutral, or no facial expression was briefly presented (for 33 ms) and masked by neutral faces that had to be evaluated. Evaluative decisions and response latencies were registered. Borderline-typical symptomatology was assessed with the Borderline Symptom List. In the total sample, valence-congruent evaluative shifts and delays of evaluative decision due to facial affect were observed. No between-group differences were obtained for evaluative decisions and latencies. The presence of comorbid anxiety disorders was found to be positively correlated with evaluative shifting owing to masked happy primes, regardless of baseline-neutral or no facial expression condition. The presence of comorbid depressive disorder, paranoid personality disorder, and symptoms of social isolation and self-aggression were significantly correlated with response delay due to masked angry faces, regardless of baseline. In the present affective priming study, no abnormalities in the automatic recognition and processing of facial affects were observed in BPD patients compared to healthy individuals. The presence of comorbid anxiety disorders could make patients more susceptible to the influence of a happy expression on judgment processes at an automatic processing level. Comorbid depressive disorder, paranoid personality disorder, and symptoms of social isolation and self-aggression may enhance automatic attention allocation to threatening facial expressions in BPD. Increased automatic vigilance for social threat stimuli might contribute to affective instability and interpersonal problems in specific patients with BPD.

This study aimed to test the reliability of unaided naked-eye examination (UNEE) of the cervix as a sole cervical cancer screening test in a developing country setup compared with the standard cervical cytology. A total of 3,500 nonpregnant women aged between 25 and 55 years were included. An unlubricated bivalve speculum was inserted into the vagina under good light to visualize the cervix. A thorough UNEE of the cervix was done to detect any apparent lesions. Cervical smears were obtained using the long tip of an Ayre spatula. An additional endocervical sample was obtained by cytobrush. Women with abnormal Pap smears or visible cervical lesions by UNEE were scheduled for colposcopic examination. A biopsy specimen was obtained in every abnormal colposcopic examination. Of 3,500 cases, there were 9 (2.57%) preinvasive cervical lesions (cervical intraepithelial neoplasia 1-3) diagnosed with various diagnostic tools used in the study and confirmed by histopathologic examination. Of 3,500 cases, invasive cervical lesions were diagnosed in 6 (1.71%). The sensitivity of UNEE is much better than that of Pap smear (80% vs 60%) but less than that of colposcopy (86.7%). However, the specificity of UNEE (100%) is lower than that of Pap smear (91.16%) and better than that colposcopy (83.12%). The UNEE has a poor positive predictive value (3.75%) when compared with Pap smear (100%) and colposcopy (20%). The negative predictive values of the 3 tests were nearly comparable. Whenever access to Pap smear is limited, UNEE performed by general gynecologists and well-trained nurses is an acceptable alternative for detecting cervical premalignant or malignant lesions especially in low-resource settings.

The Faroe Islands have had nationally organised cervical cancer screening since 1995. Women aged 25-60 years are invited every third year. Participation is free of charge. Although several European overviews on cervical screening are available, none have included the Faroe Islands. Our aim was to provide the first description of cervical cancer screening, and to determine the screening history of women diagnosed with cervical cancer in the Faroe Islands. Screening data from 1996 to 2012 were obtained from the Diagnostic Centre at the National Hospital of the Faroe Islands. They included information on cytology and HPV testing whereas information on histology was not registered consistently. Process indicators were calculated, including coverage rate, excess smears, proportion of abnormal cytological samples, and frequency of HPV testing. Data on cervical cancer cases were obtained from the Faroese Ministry of Health Affairs. The analysis of the screening history was undertaken for cases diagnosed in 2000-2010. A total of 52 457 samples were taken in 1996-2012. Coverage varied between 67% and 81% and was 71% in 2012. Excess smears decreased after 1999. At present, 7.0% of samples have abnormal cytology. Of all ASCUS samples, 76-95% were tested for HPV. A total of 58% of women diagnosed with cervical cancer did not participate in screening prior to their diagnosis, and 32% had normal cytology in the previous four years. Despite the difficult geographical setting, the organised cervical cancer screening programme in the Faroe Islands has achieved a relatively high coverage rate. Nevertheless, challenges, e.g. consistent histology registration and sending reminders, still exist.

The aim of this paper was to evaluate the parameters of blood count and tumor markers in borderline ovarian tumors. We evaluated 21 patients who had confirmed histopathologic diagnosis of borderline ovarian tumor. We recorded age, parity, tumor type, stage of cancer, serum levels of tumor markers (CA-125, CA-15.3, CA-19.9, CEA, AFP), and the parameters of blood count, fasting glucose, disease-free survival and overall. The patients were divided into two groups, stage IA (n = 13) and stage IB-IIIC (n = 8). The unpaired t-test and Fisher's exact test were used, with P values of less than 0.05 being considered to indicate statistical significance. Levels of red blood cells, hematocrit, and hemoglobin were significantly higher in stage IA when compared with stage IB-IIIC (P < 0.05). The levels of tumor marker CEA had a tendency to be higher in the group stage IB-IIIC (0.08). Abnormal levels of CEA and CA-19.9 were found more frequently in stages IB-IIIC. Therefore, parameters of blood count, CEA, and CA-19.9 should be targeted for further research in identifying prognostic factors in borderline tumors.

This study aimed to evaluate the ultrasonographic pattern of cervical lymph nodes (CLNs) and whether levothyroxine with prednisone therapy is effective for lymphadenopathy in patients with Hashimoto thyroiditis (HT). This retrospective study was looking at patients with confirmed diagnosis of HT who underwent comprehensive neck ultrasound examination. We reviewed sonographic findings in 127 patients with HT, 234 euthyroid patients with goiter, and 122 healthy subjects. In addition, 30 untreated HT patients with cervical lymphadenopathy were recruited for the levothyroxine with prednisone therapy. We rescanned the patients 9 months after treatment with levothyroxine and prednisone. Patients with HT had a higher rate of CLN detection on ultrasound than euthyroid patients with goiter and healthy subjects at cervical levels III, IV, and VI (P < 0.01). In addition, patients with HT had a higher rate of detection of CLNs with abnormal sonographic features than the other 2 groups, most notably at cervical levels III, IV, and VI (P < 0.01). After the treatment, the mean thyroid volume, thyroid nodule volume, CLN volume, symptom score, and cosmetic grade of 30 HT patients were remarkably decreased (P < 0.01 or P < 0.001). Hashimoto thyroiditis seems to be associated with an increased rate of detection of CLNs with abnormal sonographic features, particularly at cervical levels III, IV, and VI. Therapy with levothyroxine with prednisone is effective for cervical lymphadenopathy in patients with HT.

Contemporary theories of cervical carcinogenesis: the virus, the host, and the stem cell.

Crum, C P

Cervical cancer is a complex disease that, by its association with human papillomavirus (HPV), has elicited research in a broad range of areas pertaining to its basic diagnostic and clinical aspects. The complexity of this association lies not only in the fundamental relationship between virus and cancer but also in its translation to pathologic diagnosis and clinical management. Offshoots from the relationship of virus to pathology include studies targeting the link between papillomavirus infection and cervical epithelial abnormalities, the molecular epidemiology of papillomavirus infection, and the potential use of HPV testing as either a screening technique or a tool for managing women who have Pap smear abnormalities. A second variable that is critical to the pathogenesis of cervical neoplasia is the cervical transformation zone. The wide range of invasive and noninvasive lesion phenotypes associated with HPV infection in this region indicate that not only the virus but also specific host target epithelial cells in the transformation zone play an important part in the development of cervical neoplasia. Further understanding of this relationship between the virus and the host epithelium will hinge on determining the subtypes of epithelial cells in the transformation zone and their phenotypic response to infection. New technologies, such as expression arrays, promise to clarify, if not resolve, the complexity of molecular interactions leading to the multiplicity of tumor phenotypes associated with HPV infection of the uterine cervix.

Purpose: The expressions of six cell-cycle-associated proteins were analyzed in cervical squamous cell carcinomas in correlation in a search for prognostic correlations in tumors treated with concurrent chemoradiation therapy (cCRT). Methods and Materials: The expressions of p53, p21/waf1/cip1, molecular immunology borstel-1 (MIB-1), epidermal growth factor receptor (EGFR), human epidermal growth factor receptor type 2 (HER2), and Bcl-2 were studied using an immunohistochemical method in 57 cases of cervical squamous cell carcinoma treated with cCRT. Patients received cCRT between 1998 and 2005. The mean patient age was 61 years (range, 27-82 years). The number of patients with Stage II, III, andmore » IVA disease was 18, 29, and 10, respectively. Results: The number of patients with tumors positive for p53, p21/waf1/cip1, MIB-1, EGFR, HER2, and Bcl-2 was 26, 24, 49, 26, 13, and 11, respectively; no significant correlation was noted. The 5-year overall survival rates of HER2-positive and -negative patients was 76% vs. 44%, which was of borderline significance (p = 0.0675). No significant correlation was noted between overall survival and expressions of p53, p21/waf1/cip1, MIB-1, EGFR, and Bcl-2. No correlation was observed between local control and expression of any of the proteins. Conclusion: Expression of HER2 protein had a weak impact of borderline significance on overall survival in squamous cell carcinoma of the uterine cervix treated with cCRT. However, no clinical associations could be established for p53, p21/waf1/cip1, MIB-1, EGFR, and Bcl-2 protein expressions.« less

The aim of this retrospective study of 330 rabbits (164 males, 166 females) was to determine different vertebral formulas and prevalence of congenital vertebral anomalies in rabbits from radiographs of the cervical (C), thoracic (Th), lumbar (L) and sacral (S) segments of the vertebral column. The number of vertebrae in each segment of vertebral column, position of anticlinal vertebra and localisation and type of congenital abnormalities were recorded. In 280/330 rabbits (84.8%) with normal vertebral morphology, seven vertebral formulas were identified: C7/Th12/L7/S4 (252/330, 76.4%), C7/Th12/L6/S4 (11/330, 3.3%), C7/Th13/L7/S4 (8/330, 2.4%), C7/Th12/L7/S5 (4/330, 1.2%), C7/Th12/L8/S4 (3/330, 0.9%), C7/Th12/L7/S6 (1/330, 0.3%) and C7/Th11/L7/S4 (1/330, 0.3%). The anticlinal vertebra was identified as Th10 in 56.4% of rabbits and Th11 in 42.4% of rabbits. Congenital spinal abnormalities were identified in 50/330 (15.2%) rabbits, predominantly as a single pathology (n=44). Transitional vertebrae represented the most common abnormalities (n=41 rabbits) in the thoracolumbar (n=35) and lumbosacral segments (n=6). Five variants of thoracolumbar transitional vertebrae were identified. Cervical butterfly vertebrae were detected in three rabbits. One rabbit exhibited three congenital vertebral anomalies: cervical block vertebra, thoracic hemivertebra and thoracolumbar transitional vertebra. Five rabbits exhibited congenital vertebral abnormalities with concurrent malalignment, specifically cervical kyphosis/short vertebra (n=1), thoracic lordoscoliosis/thoracolumbar transitional vertebrae (n=1), thoracic kyphoscoliosis/wedge vertebrae (n=2) and thoracolumbar lordoscoliosis/thoracolumbar transitional vertebrae/lumbosacral transitional vertebrae (n=1). These findings suggest that vertebral columns in rabbits display a wide range of morphologies, with occasional congenital malformations. Copyright © 2018 Elsevier Ltd. All rights reserved.

While rheumatic heart disease (RHD) is a treatable disease nearly eradicated in the United States, it remains the most common form of acquired heart disease in the developing world. This study used echocardiographic screening to determine the prevalence of RHD in children in American Samoa. Screening took place at a subset of local schools. Private schools were recruited and public schools underwent cluster randomization based on population density. We collected survey information and performed a limited physical examination and echocardiogram using the World Heart Federation protocol for consented school children aged 5-18 years old. Of 2200 students from two private high schools and two public primary schools, 1058 subjects consented and were screened. Overall, 133 (12.9%) children were identified as having either definite (3.5%) or borderline (9.4%) RHD. Of the patients with definitive RHD, 28 subjects had abnormal mitral valves with pathologic regurgitation, three mitral stenosis, three abnormal aortic valves with pathologic regurgitation, and seven borderline mitral and aortic valve disease. Of the subjects with borderline disease, 77 had pathologic mitral regurgitation, 12 pathologic aortic regurgitation, and 7 at least two features of mitral valve disease without pathologic regurgitation or stenosis. Rheumatic heart disease remains a major cause of morbidity and mortality worldwide. The prevalence of RHD in American Samoa (12.9%) is to date the highest reported in the world literature. Echocardiographic screening of school children is feasible, while reliance on murmur and Jones criteria is not helpful in identifying children with RHD.

The rates of participation in the Korean nationwide cervical cancer screening program and the rates of abnormal test results were determined. The database of the National Health Insurance Service (NHIS) was used during the study period (2009-2014). The participation rate increased from 41.10% in 2009 to 51.52% in 2014 (annual percentage change, 4.126%; 95% confidence interval [CI]=2.253-6.034). During the study period, women ≥70 years of age had the lowest rate of participation (range, 21.7%-31.9%) and those 30-39 years of age the second-lowest (27.7%-44.9%). The participation rates of National Health Insurance beneficiaries (range, 48.6%-52.5%) were higher than those of Medical Aid Program (MAP) recipients (29.6%-33.2%). The rates of abnormal results were 0.65% in 2009 and 0.52% in 2014, with a decreasing tendency in all age groups except the youngest (30-39 years). Every year the abnormal result rates tended to decrease with age, from the age groups of 30-39 years to 60-69 years but increased in women ≥70 years of age. The ratio of patients with atypical squamous cells of undetermined significance compared with those with squamous intraepithelial lesions increased from 2.71 in 2009 to 4.91 in 2014. Differences related to age and occurring over time were found in the rates of participation and abnormal results. Further efforts are needed to encourage participation in cervical cancer screening, especially for MAP recipients, elderly women and women 30-39 years of age. Quality control measures for cervical cancer screening programs should be enforced consistently. Copyright © 2017. Asian Society of Gynecologic Oncology, Korean Society of Gynecologic Oncology

There is limited understanding of the association between barriers to care and clinical outcomes within patient navigation programs. Secondary analyses of data from the intervention arms of the Patient Navigation Research Program were performed, which included navigated participants with abnormal breast and cervical cancer screening tests from 2007 to 2010. Independent variables were: 1) the number of unique barriers to care (0, 1, 2, or ≥3) documented during patient navigation encounters; and 2) the presence of socio-legal barriers originating from social policy (yes/no). The median time to diagnostic resolution of index screening abnormalities was estimated using Kaplan-Meier cumulative incidence curves. Multivariable Cox proportional hazards regression examined the impact of barriers on time to resolution, controlling for sociodemographics and stratifying by study center. Among 2600 breast screening participants, approximately 75% had barriers to care documented (25% had 1 barrier, 16% had 2 barriers, and 34% had ≥3 barriers). Among 1387 cervical screening participants, greater than one-half had barriers documented (31% had 1 barrier, 11% had 2 barriers, and 13% had ≥3 barriers). Among breast screening participants, the presence of barriers was associated with less timely resolution for any number of barriers compared with no barriers. Among cervical screening participants, only the presence of ≥2 barriers was found to be associated with less timely resolution. Both types of barriers, socio-legal and other barriers, were found to be associated with delay among breast and cervical screening participants. Navigated women with barriers resolved cancer screening abnormalities at a slower rate compared with navigated women with no barriers. Further innovations in navigation care are necessary to maximize the impact of patient navigation programs nationwide. © 2015 American Cancer Society.

Summary Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infection. Questionnaires were administered to 200 FSWs aged 18–26 years in Lima, Peru, to gather risk behaviours, and cervical swab samples were collected for Pap smears and HPV DNA testing as part of a longitudinal study. Participants reported a median of 120 clients in the past month, and 99.2% reported using condoms with clients. The prevalence of any HPV in cervical samples was 66.8%; 34 (17.1%) participants had prevalent HPV 16 or 18, and 92 (46.2%) had one or more oncogenic types. Fifteen women had abnormal Pap smears, 13 of which were HPV DNA positive. Fewer years since first sex was associated with oncogenic HPV prevalence in a model adjusted for previous sexually transmitted infection (STI) status and condom use with partners (prevalence ratio = 0.77, 95% confidence interval [CI] = 0.60–0.97). Our data confirm the high rates of HPV transmission among FSWs in Peru, highlighting the need for early and effective strategies to prevent cervical cancer. PMID:22581946

1995-01-01

AIMS--To establish whether abnormalities in the course of the vertebral artery occur and whether they are relevant to arterial injury associated with head and neck movements. METHODS--Twenty vertebral arteries were carefully dissected at necropsy and abnormalities in course were noted, along with any other bony or cartilaginous cervical anomalies. The effect of head and neck movement on these vessels was studied before a detailed histomorphometric examination was undertaken on sections of the excised arteries. RESULTS--Five vessels had an abnormal course. One vessel entered the transverse foramina of the fifth cervical vertebra rather than the sixth, but was otherwise normal. In two subjects both vertebral arteries were abnormal in the upper cervical portion with, in each case, a straight left vertebral artery and a right vertebral artery with a deficient loop, closely applied to the atlanto-axial joint. Both of these subjects also had completely ossified stylohyoid ligaments and the arteries visibly stretched with modest head and neck movements. Histology revealed variable degrees of smooth muscle disarray in the tunica media of two of the arteries with loop deficiencies. The circumference of one of the straight arteries was smaller than expected but in all other measured histomorphometric parameters these vessels appeared normal. CONCLUSIONS--Vertebral artery loops are deficient in a number of subjects. This finding is important given the recently described biomechanical susceptibility of the vertebral artery to longitudinal extension and may explain the smooth muscle changes, in that this may represent attempts at arterial wall remodelling. Subjects with such loop deficiencies may be more susceptible to a variety of head and neck insults and such abnormalities should be sought at necropsy in subjects who die as a result of fatal vertebral artery injury.

Twenty-five women scheduled for hysterectomy for nonmalignant disease participated in the study. Sperm storage in endocervical crypts was examined in three groups of patients: nine women pretreated with estrogen and inseminated with normal semen, nine women pretreated with gestagen and inseminated with normal semen, and seven women pretreated with estrogen and inseminated with abnormal semen. The number of crypts containing spermatozoa (colonized crypts) and the sperm density per crypt were examined in serially sectioned cervices. In estrogen-pretreated cervices both the percentage of colonized crypts and the sperm density were significantly higher than in gestagen-pretreated cervices. Large and giant crypts proved to be the main storage facility for spermatozoa. The localization of crypts along the endocervical canal did not influence sperm storage. The quality of semen appeared to be of critical importance to sperm storage. The percentage of colonized crypts and sperm density were severly reduced in patients inseminated with abnormal semen.

The world age-standardised prevalence of high-risk HPV (hrHPV) infection among 5038 UK women aged 20–59 years, with a low-grade smear during 1999–2002, assessed for eligibility for TOMBOLA (Trial Of Management of Borderline and Other Low-grade Abnormal smears) was 34.2%. High-risk HPV prevalence decreased with increasing age, from 61% at ages 20–24 years to 14–15% in those over 50 years. The age-standardised prevalence was 15.1, 30.7 and 52.7%, respectively, in women with a current normal, borderline nuclear abnormalities (BNA) and mild smear. In overall multivariate analyses, tertiary education, previous pregnancy and childbirth were associated with reduced hrHPV infection risk. Risk of infection was increased in non-white women, women not married/cohabiting, hormonal contraceptives users and current smokers. In stratified analyses, current smear status and age remained associated with hrHPV infection. Data of this type are relevant to the debate on human papillomavirus (HPV) testing in screening and development of HPV vaccination programmes. PMID:17519896

Trade-offs in Cervical Cancer Prevention: Balancing Benefits and Risks

Stout, Natasha K.; Goldhaber-Fiebert, Jeremy D.; Ortendahl, Jesse D.; Goldie, Sue J.

2009-01-01

Background New screening and vaccination technologies will provide women with more options for cervical cancer prevention. Because the risk of cervical cancer diminishes with effective routine screening, women may wish to consider additional attributes, such as the likelihood of false-positive results and diagnostic procedures for mild abnormalities likely to resolve without intervention in their screening choices. Methods We used an empirically calibrated simulation model of cervical cancer in the United States to assess the benefits and potential risks associated with prevention strategies differing by primary screening test, triage test for abnormal results (cytologic testing, human papillomavirus [HPV] DNA test), and screening frequency. Outcomes included colposcopy referrals, cervical intraepithelial neoplasia (CIN) types 1 and 2 or 3, lifetime cancer risk, and quality-adjusted life expectancy. Results Across strategies, colposcopy referrals and diagnostic workups varied 3-fold, although diagnostic rates of CIN 2 or 3 were similar and 95% of positive screening test results were for mild abnormalities likely to resolve on their own. For a representative group of a thousand 20-year-old women undergoing triennial screening for 10 years, we expect 1038 colposcopy referrals (7 CIN 2 or 3 diagnoses) from combined cytologic and HPV DNA testing and fewer than 200 referrals (6–7 CIN 2 or 3 diagnoses) for strategies that use triage testing. Similarly, for a thousand 40-year-old women, combined cytologic and HPV DNA testing led to 489 referrals (9 CIN 2 or 3), whereas alternative strategies resulted in fewer than 150 referrals (7–8 CIN 2 or 3). Using cytologic testing followed by triage testing in younger women minimizes both diagnostic workups and positive HPV test results, whereas in older women diagnostic workups are minimized with HPV DNA testing followed by cytologic triage testing. Conclusions Clinically relevant information highlighting trade-offs among cervical cancer prevention strategies allows for inclusion of personal preferences into women’s decision making about screening and provides additional dimensions to the construction of clinical guidelines.

Cervical cancer is one of the most common cancers among women in the world and in the Middle East. Its prevention and screening strategies assume great importance especially in view of the ability to identify the illness at an early stage and disrupt its progression toward neoplasia. Cervical cancer screening program of our center in UAE as well as this study is oriented in this direction. Cervical cytology data encompassing 4 years (2011-2014) was compiled and analyzed for 14,950 cases to assess the abnormal smear reporting pattern, correlation with biopsy histopathology, HPV high-risk screening data, and HPV genotype prevalence among patients with abnormal smear test, as well as in relation to the respective nationalities of patients. Abnormal smear rates as well as HPV high-risk positivity correlated well with established data. Cytology-histology correlation was good. HPV high-risk type 16 was the commonest, type 18 which is the second common type worldwide was less frequently detected, several other high risk subtypes such as 51, 31 as well as rare types such as 66, 56, and 59 were detected in a significant number of patients. Assessment of cervical cytology reporting pattern, correlation of cervical cytology with HPV molecular diagnosis, and biopsy histopathology is a useful way to audit our work and a good quality control practice. Higher prevalence of HPV HR types such as type 51, 31 as well as 66, 56, and 59 found in the present as well as many similar other studies apart from the commonest subtype 16 may imply necessity for development of more targeted and multivalent anti-HPV vaccines for protection of women in our region. HPV genotypes correlation with the nationalities of patients is useful from an epidemiological standpoint to plan preventive strategies. © 2015 Wiley Periodicals, Inc.

Cytogenetic characterization of three cell lines derived from primary cervical tumors of different histologic grade

DOE Office of Scientific and Technical Information (OSTI.GOV)

Hann, E.; Beauregard, L.; Mikumo, R.

Braum et al.(1993) established three cell lines from keratinizing and nonkeratinizing cervical carcinomas. These cell lines were subsequently analyzed for growth properties and the physical state of the human papillomavirus type 16 genome. TC140, derived from a keratinizing cervical tumor, contains human papillomavirus type 16 in the episomal state. TC-146A and TC-146B, derived from a nonkeratinizing large-cell cervical carcinoma, contain human papillomavirus type 16 in the integrated state. The goal of the present study was to cytogenetically characterize these cell lines, developed from cervical carcinoma with a defined histopathology, in order to shed additional light on the biological basis ofmore » the histological and clinical heterogeneity of cervical cancers. Information on solid tumors has been limited because they are often difficult to culture and the karyotypes on the available metaphases are often complex with unidentifiable markers. The chromosomes of these three cell lines were characterized in the present study using GTG-banding. For cell line 140, the most striking chromosomal abnormalities noted were the presence of an i(5p) or i(12p) marker, an isochromosome 8q marker and multiple copies of chromosome 9. For cell line 146A, the most notable chromosomal abnormalities noted were the presence of a marker chromosome 7 with additional materials present on the long arms, an isochomosome of the long arms of chromosome 8 and a question of chromosome 19 markers. For cell line 146B, the most notable chromosomal abnormalities were found to be a deleted X chromosome, a marker chromosome 7 with additional material on the long arm, an isochromosome 8q marker, and isochromosome 16q marker and one or more copies of an isochromosome 17q marker. Fluorescent in situ hybridization experiments performed using select probes further corroborate the results of the above-mentioned conventional cytogenetic studies.« less

Objective In 2006, the American Society for Colposcopy and Cervical Pathology (ASCCP) updated evidence based guidelines recommending screening intervals for women with abnormal cervical cytology. In our low-income inner city population, we sought to improve performance by uniformly applying the guidelines to all patients. We report the prospective performance of a comprehensive tracking, evidence-based algorithmically driven call-back and appointment scheduling system for cervical cancer screening in a resource-limited inner city population. Materials and Methods Outreach efforts were formalized with algorithm-based protocols for triage to colposcopy, with universal adherence to evidence-based guidelines. During implementation from August 2006 through July 2008, we prospectively tracked performance using the electronic medical record with administrative and pathology reports to determine performance variables such as the total number of Pap tests, colposcopy visits, and the distribution of abnormal cytology and histology results, including all CIN 2,3 diagnoses. Results 86,257 gynecologic visits and 41,527 Pap tests were performed system-wide during this period of widespread and uniform implementation of standard cervical cancer screening guidelines. The number of Pap tests performed per month varied little. The incidence of CIN 1 significantly decreased from 117/171 (68.4%) the first tracked month to 52/95 (54.7%) the last tracked month (p=0.04). The monthly incidence rate of CIN 2,3, including incident cervical cancers did not change. The total number of colposcopy visits declined, resulting in a 50% decrease in costs related to colposcopy services and approximately a 12% decrease in costs related to excisional biopsies. Conclusions Adherence to cervical cancer screening guidelines reduced the number of unnecessary colposcopies without increasing numbers of potentially missed CIN 2,3 lesions, including cervical cancer. Uniform implementation of administrative-based performance initiatives for cervical cancer screening minimizes differences in provider practices and maximizes performance of screening while containing cervical cancer screening costs.

Background. Uptake of human papillomavirus (HPV) vaccine in the United States is slow, and the effectiveness of the vaccine has not been assessed in high-risk adolescent populations. Methods. We conducted a longitudinal study of 1139 sexually active, inner-city adolescent women receiving the 3-dose quadrivalent (4vHPV) vaccine. Cervical and anal specimens collected semiannually were tested using an L1-specific polymerase chain reaction assay. Postvaccination incidence of 4vHPV vaccine and nonvaccine HPV types, and risk of cervical cytological abnormalities, were assessed in relation to time to completion of all 3 vaccine doses. Results. Compared to vaccine naive women at enrollment, vaccinated women had significantly lower incidence rate ratios of cervical infection with HPV6/11/16/18 (0.2; 95% confidence interval [CI], .1–.4) and the related types HPV31 and HPV45 (0.4 [95% CI, .2–1.0] and 0.3 [95% CI, .1–.6], respectively), as well as significantly lower incidence rate ratios of anal infection with HPV6/11/16/18 (0.4; 95% CI, .2–.7). Notably, we observed higher risks of cervical HPV6/11/16/18 infection (hazards ratio [HR], 2.9; 95% CI, 1.0–8.0) and associated cytological abnormalities (HR, 4.5; 95% CI, .7–26.0) among women immunized at ≥15 years of age who took ≥12 months (vs <12 months) to complete the 3-dose regimen. Conclusions. Among adolescents immunized at ≥15 years of age, a longer time to complete the 3-dose schedule was associated with an increased risk of anogenital HPV6/11/16/18 infection and an increased incidence of associated cervical cytological abnormalities.

We studied harms related to cervical cancer screening and management of screen-positive women in the United States (US) and the Netherlands. We utilized data from four US integrated health care systems (SEARCH), the US National Health Interview Survey, New Mexico state, the Netherlands national histopathology registry, and included studies on adverse health effects of cervical screening. We compared the number of Papanicolaou (Pap) smear tests, abnormal test results, punch biopsies, treatments, health problems (anxiety, pain, bleeding and discharge) and preterm births associated with excisional treatments. Results were age-standardized to the 2007 US population. Based on SEARCH, an estimated 36 million Pap tests were performed in 2007 for 91 million US women aged 21-65 years, leading to 2.3 million abnormal Pap tests, 1.5 million punch biopsies, 0.3 million treatments for precancerous lesions, 5 thousand preterm births and over 8 million health problems. Under the Netherlands screening practice, fewer Pap tests (58%), abnormal test results (64%), punch biopsies (75%), treatment procedures (40%), preterm births (60%) and health problems (63%) would have occurred. The SEARCH data did not differ much from other US data for 2007 or from more recent data up to 2013. Thus compared to the less intensive screening practice in the Netherlands, US practice of cervical cancer screening may have resulted in two- to threefold higher harms, while the effects on cervical cancer incidence and mortality are similar. The results are also of high relevance in making recommendations for HPV screening. Systematic collection of harms data is needed for monitoring and for better incorporation of harms in making screening recommendations. © 2016 UICC.

Infection with certain types of human papillomavirus (HPV) has been associated with the development of cervical and anal cancer. Worldwide, the incidence of anal cancer has increased markedly. The present study aimed to evaluate the prevalence of HPV infection of the uterine cervix and anal canal in human immunodeficiency virus (HIV)- and non-HIV-infected risk populations. Cervical and anal HPV swabs and cytology samples were collected from 287 patients at the University Hospital of Munich, Germany between 2011 and 2013. Patients were divided into HIV-negative controls (G1) and two risk groups, including HIV-negative patients with cytological abnormalities of the cervix (G2) and HIV-infected patients (G3). Data, including clinical parameters, were analysed. The risk groups had significantly more positive results for HPV in the anus (71.03 and 83.15% for G2 and G3, respectively), as compared with G1. The predominant HPV genotypes found in the anus were high-risk HPV genotypes, which were significantly correlated with concomittant cervical HPV findings. In the risk groups, a significant association between the cytological findings and HPV detection in the cervix was found, while the results of the anus revealed no significance. The results of the present study suggested that the prevalence of HPV infection in the anal canal of risk populations is high. Furthermore, patients with abnormal cervical cytology results and HIV-infected women, irrespective of their individual cervical findings, may have a risk of concomittant anal high-risk HPV infection. Based on the predominant HPV genotypes found in the study, HPV vaccination could reduce the incidence of anal cancer. Nevertheless, high-risk patients should be intensively screened for anal squamous intraepithelial abnormalities to avoid invasive cancer stages.

Cervical cancer is caused by infection with high risk human papillomavirus (HR-HPV). Inducible nitric oxide synthase (iNOS), a soluble factor involved in chronic inflammation, may modulate cervical cancer risk among HPV infected women. The aim of the study was to measure and correlate plasma nitrite/nitrate levels with tissue specific expression of iNOS mRNA among women with different grades of cervical lesions and cervical cancer. Tissue biopsy and plasma specimens were collected from 120 women with cervical neoplasia or cancer (ASCUS, LSIL, HSIL and invasive cancer) and 35 women without cervical abnormalities. Inducible nitric oxide synthase (iNOS) mRNA from biopsy and plasma nitrite/nitrate levels of the same study subjects were measured. Single nucleotide polymorphism (SNP) analysis was performed on the promoter region and Ser608Leu (rs2297518) in exon 16 of the iNOS gene. Differences in iNOS gene expression and plasma nitrite/nitrate levels were compared across disease stage using linear and logistic regression analysis. Compared to normal controls, women diagnosed with HSIL or invasive cancer had a significantly higher concentration of plasma nitrite/nitrate and a higher median fold-change in iNOS mRNA gene expression. Genotyping of the promoter region showed three different variations: A pentanucleotide repeat (CCTTT) n, -1026T > G (rs2779249) and a novel variant -1153T > A. These variants were associated with increased levels of plasma nitrite/nitrate across all disease stages. The higher expression of iNOS mRNA and plasma nitrite/nitrate among women with pre-cancerous lesions suggests a role for nitric oxide in the natural history of cervical cancer. Copyright © 2015.

Background: Although cervical dilatation curves are crucial for appropriate management of labor progression, abnormal labor progression and obstetric interventions were included in previous and widely-used cervical dilatation curves. We aimed to describe the cervical dilatation curves of normal labor progression in pregnant Japanese females without abnormal labor progression and obstetric interventions. Methods: We completed retrospective obstetric record reviews on 3172 pregnant Japanese females (parity = 0, n = 1047; parity = 1, n = 1083; parity ≥ 2, n = 1042), aged 20 to 39 years old at delivery, with pregravid body mass indices of less than 30. All patients underwent spontaneous deliveries with term, singleton, cephalic and live newborns of appropriate-for-gestational age birthweight, without adverse neonatal outcomes. We characterized labor progression patterns by examining the relationship between elapsed times from the full dilatation and cervical dilatation stages, and labor durations by examining the distribution of time intervals from one cervical dilatation stage, to the next, and ultimately to the full dilatation. Results: Fastest cervical changes occurred at 6 cm (primiparas) and 5 cm (multiparas) of dilatation. The 95%tile of labor progression took over 3 hours to progress from 6 cm to 7 cm (primiparas), and over 2 hours to progress from 5 cm to 6 cm (multiparas). The 5%tile of traverse time to the full dilatation, during the active phase, was less than 1 hour (primiparas) and 0.5 hours (multiparas). At the end of the active phase, no deceleration phase was observed. Conclusions: Active labor may not start until 5 cm of dilatation. At the beginning of the active phase, cervical dilatation was slower than previously described. These results may reduce opportunities for obstetric interventions during labor progression.

In this study we aimed to investigate high-risk human papilloma virus (hrHPV) prevalence among Turkish women. Cervical samples were collected from 501 women for cytological screening and hrHPV testing by Digene Hybrid Capture 2. hrHPV prevalence and its relation with cytological results and epidemiologic data were analysed by SPSS. The prevalence of hrHPV was 4.2% (21 of the 501 women). Women with abnormal cytological screening results have significantly higher risk of hrHPV positivity compared with women with normal cytological results (19% vs 3.5%) (p ≤ 0.01). The incidence of HPV infection was only associated with the number of sexual partners, but there was no association with age, contraception methods or age at the first sexual intercourse. The prevalence of hrHPV among histological-confirmed cervical intraepithelial neoplasia (CIN) 1, CIN 2 and normal cases were found as 37.5%, 25% and 25%, respectively. The prevalence of cervical hrHPV infection is 4.2% in our population and this rate seems lower than reported rates from other regions. According to further studies with a larger sample size, reflex cytology based on hrHPV positivity should be considered for our national cervical cancer screening programme.

Verification of uncertain PAP-smear results in a group of women covered by the cervical screening program in the Podlaski province. The main aim of the study was to identify CIN (Cervical Intraepithelial Neoplasia) lesions present, with varying degrees of severity in women with cytological diagnosis of ASCUS (atypical squamous cells of undetermined significance), LSIL (low grade squamous intraepithelial lesion), and ASC-H (atypical squamous cells - cannot exclude high grade squamous intraepithelial lesion). The study evaluated 101 cervical smears taken from the vaginal part of the cervix in a group of screened women in the Podlaski province. Cytological evaluation was performed according the Bethesda System. We analyzed abnormal smears selected from a total of 7296 cytological examinations performed during 2012 at the University Center for Pathomorphological and Genetic - Molecular Diagnosis, Medical University in Białystok. The cytological results which were of interest to us included 19 cases with ASCUS, 59 with LSIL, and 23 with ASC-H, as well as with morphological features of the presence of Human Papilloma Virus (HPV). Staining was performed using CINtecPLUS test according to the manufacturer's instructions. CINtecPLUS is a immunocytochemical test based on specially designed monoclonal antibodies (E6H4TM) that let us identify protein p16ink4a within the cervical smear Additionally the diagnostic kit was provided with antibodies for diagnosing the presence of Ki-67 protein, a known marker of cell proliferation. The result was considered positive when staining of the nucleus and the cytoplasm appeared in red and brown, respectively. All abnormal results were eventually verified by histological examination of the tissue taken from cervical lesions by diagnostic-therapeutic procedure following colposcopic evaluation of cervical lesion topography In the group of cytological smears with ASCUS, the diagnosis was positive in 5 cases (26.3%), negative in 14 (73.7%). In the group with the diagnosis of LSIL, the cytology results were positive in 32 cases (54.2%), negative in 27 (45.8%). In the cytological diagnosis of ASC-H there were 20 positive (87%) and 3 negative (13%) results. Test CINtecPLUS could be a helpful tool in the final diagnosis of cervical abnormality in patients with the cytological diagnosis of ASCUS, LSIL and ASC-H. The combination of conventional cytological test and CINtecPLUS can help create a new procedure algorithm for cases with abnormal or ambiguous cytological screening results. It could be especially useful in a group of young women of childbearing age, when it is common to avoid a more radical treatment of cervical lesions.

We report staged treatment of severe combined spinal deformity in an 11-year-old patient with Ollier disease and abnormal cervical vertebra. Combined scoliosis with systemic pathology and abnormal vertebrae is a rare condition and features atypical deformity location and rapid progression rate and frequently involves the rib cage and pelvis, disturbing the function of chest organs and skeleton. Progressive deformity resulted in cachexia and acute respiratory failure. A halo-pelvic distraction device assembled of Ilizarov components was employed for a staged surgical treatment performed for lifesaving indications. After vital functions stabilized, the scoliosis curve of the cervical spine was corrected and fixed with a hybrid system of transpedicular supporting points, connecting rods, and connectors that provided staged distraction during growth. The treatment showed good functional and cosmetic result. PMID:24436859

Higher rate of statin-related hepatotoxicity has been reported for Koreans than for Westerners. Moreover, statin-related aminotransferase elevation for those who show borderline levels of aspartate transaminase (AST) and alanine transaminase (ALT) (≤×3 of UNL) at baseline has not been fully investigated. Post-statin changes AST/ALT levels during the first year for 21 233 Korean outpatients at two large academic teaching hospitals from January 2009 to December 2013 were analysed using electronic health record data. The date of the first statin prescription was set as baseline. We also performed a comparative analysis of statin-related AST/ALT elevations according to the type of statin, followed by an analysis of clinical risk factors. The progression rate to abnormal AST/ALT values [>×3 the upper normal limit (UNL)] was significantly higher (2·4-16% vs. 0·3-1·7%, P < 0·001) in subjects with borderline (>×1, but ≤×3 of UNL) compared with normal AST/ALT values at baseline. Those with normal baseline AST/ALT did not show significantly different progression rate between different statin medications (P = 0·801). However, patients taking pitavastatin (HR = 0·76, P = 0·657) were least likely to develop abnormal AST/ALT, whereas those taking fluvastatin (HR = 2·96, P = 0·029) were the most likely to develop abnormal AST/ALT compared with atorvastatin for patients who were with baseline borderline AST/ALT. However, given the small sample sizes and the observational nature of our study, these need further study. It is advisable to regularly monitor AST/ALT levels even in patients with AST/ALT increases >×1. Future studies should aim to determine the possible risk factors for each specific statin type by analysing various confounding variables. © 2016 The Authors.

Objective: Compare an inexpensive cell-phone based Mobile Colposcope, with a standard colposcope in the evaluation of women with abnormal Pap smear screening. Methodology: The study was a prospective, parallel noninferiority trial. Thirty women underwent colposcopy for the evaluation of an abnormal Pap smear. After application of acetic acid, images of the cervix were obtained with both a standard colposcope and the Mobile Colposcope. An additional set of images using both devices were obtained using the red-free (green filter) mode. Eight experienced gynecologists then evaluated 100 paired images (plain and green filter) from two different sites in random order using a web based assessment program. After reviewing each set of paired images, the expert would make an assessment of: 1) normal (no biopsy/ random biopsy), or 2) abnormal. For abnormal images, the expert then electronically marked the site(s) on the image where a biopsy was recommended. In image analysis, the cervical image was divided into 12 radial sectors and the marked sites for biopsy on the matched pairs were compared. Matched pairs that were considered normal, or those where biopsy site recommendations were within +/- 30° were considered equivalent; unmatched biopsy sites were considered non-equivalent. Results were compared using Wilcoxon Matched Pairs Signed Ranks Test. Expert assessment of Mobile Colposcope images compared with assessment by standard colposcope is currently onging. Conclusions: if the Mobile Colposcope demonstrates non-inferiority to imaging obtained with a standard colposcope and due to its low cost, it has the potential help improve cervical cancer screening in low resource settings.

In 2014, liquid-based cytology with HPV triage replaced conventional cytology. The aim of our study was to compare conventional and liquid-based cytology (LBC), estimate the prevalence of abnormal cervical cytology and high risk HPV (hrHPV) infection and their correlation, among screened women in Luxembourg. Between the first January 2013 and 31st December 2015, 315,868 cervical samples from 150,815 women (mean age 42.2 years) were investigated by the national cytology laboratory. Slides were prepared and screened according to European Guidelines. All cytological results were classified according to the Bethesda 2001 system terminology. The prevalence of abnormal cervical lesions was as follows: atypical squamous cells of undetermined significance (ASC-US), 1.3%; low-grade squamous intraepithelial lesion (LSIL), 1.9%; high-grade squamous intraepithelial lesion (HSIL), 0.4%. The detection rate of cytological lesions was significantly higher with LBC than with conventional cytology. Based on 11,838 samples with concomitant cytology and HPV testing, hrHPV was detected in 9.5, 45.3, 70.0, and 92.6% of women with negative cytology, ASC-US, LSIL, and HSIL, respectively. More cervical lesions were identified using LBC compared to conventional cytology. HrHPV infection was correlated with the severity of intraepithelial lesions. The current findings provide important information to evaluate the prevention of cervical cancer in Luxembourg and for monitoring the future impact of HPV vaccination. Diagn.

Genomic aberrations in borderline ovarian tumors

PubMed Central

2010-01-01

Background According to the scientific literature, less than 30 borderline ovarian tumors have been karyotyped and less than 100 analyzed for genomic imbalances by CGH. Methods We report a series of borderline ovarian tumors (n = 23) analyzed by G-banding and karyotyping as well as high resolution CGH; in addition, the tumors were analyzed for microsatellite stability status and by FISH for possible 6q deletion. Results All informative tumors were microsatellite stable and none had a deletion in 6q27. All cases with an abnormal karyotype had simple chromosomal aberrations with +7 and +12 as the most common. In three tumors with single structural rearrangements, a common breakpoint in 3q13 was detected. The major copy number changes detected in the borderline tumors were gains from chromosome arms 2q, 6q, 8q, 9p, and 13q and losses from 1p, 12q, 14q, 15q, 16p, 17p, 17q, 19p, 19q, and 22q. The series included five pairs of bilateral tumors and, in two of these pairs, informative data were obtained as to their clonal relationship. In both pairs, similarities were found between the tumors from the right and left side, strongly indicating that bilaterality had occurred via a metastatic process. The bilateral tumors as a group showed more aberrations than did the unilateral ones, consistent with the view that bilaterality is a sign of more advanced disease. Conclusion Because some of the imbalances found in borderline ovarian tumors seem to be similar to imbalances already known from the more extensively studied overt ovarian carcinomas, we speculate that the subset of borderline tumors with detectable imbalances or karyotypic aberrations may contain a smaller subset of tumors with a tendency to develop a more malignant phenotype. The group of borderline tumors with no imbalances would, in this line of thinking, have less or no propensity for clonal evolution and development to full-blown carcinomas. PMID:20184781

In whiplash studies, there may be interpretation difficulties: are post-whiplash findings, when present, a consequence of the whiplash trauma, or did they exist prior to trauma? In the Vågå headache epidemiology study (1995-1997), there was a headache history and detailed physical/neurological findings from the face/head/neck in 1838 18-65-year-old parishioners. In September 2001, four years after the Vågå study, a search through the Health Centre files divulged six cases with whiplash trauma in the intervening period. These parishioners could thus be their own controls. Two females did not develop new complaints. In the four parishioners with apparently new, subjective complaints, i.e., headache, neck pain, and a feeling of stiffness in the neck, there were corresponding findings as regards various parameters: shoulder area skin-roll test, changes in two, possible changes in two; range of motion, neck, changes in two, borderline changes in one; "features indicative of cervical abnormality" ("CF"), changes in all four; the mean, post-whiplash stage value was: 3.6+, against 1.6+ prior to accident (Vågå: only 0.93%, "CF" exceeding 3+). In the two without new complaints, the mean "CF" value was 1.0+. The number of cases is small, but the similarity of the symptoms--and signs--following whiplash injury may suggest an element of organic origin in the whiplash syndrome.

The number of cervical vertebrae in mammals is almost constant at seven, regardless of their neck length, implying that there is selection against variation in this number. Homebox (Hox) genes are involved in this evolutionary mammalian conservation, and homeotic transformation of cervical into thoracic vertebrae (cervical ribs) is a common phenotypic abnormality when Hox gene expression is altered. This relatively benign phenotypic change can be associated with fatal traits in humans. Mutations in genes upstream of Hox, inbreeding and stressors during organogenesis can also cause cervical ribs. The aim of this study was to describe the prevalence of cervical ribs in a large group of domestic dogs of different breeds, and explore a possible relation with other congenital vertebral malformations (CVMs) in the breed with the highest prevalence of cervical ribs. By phenotyping we hoped to give clues as to the underlying genetic causes. Twenty computed tomography studies from at least two breeds belonging to each of the nine groups recognized by the Federation Cynologique Internationale, including all the brachycephalic 'screw-tailed' breeds that are known to be overrepresented for CVMs, were reviewed. The Pug dog was more affected by cervical ribs than any other breed (46%; P < 0.001), and was selected for further analysis. No association was found between the presence of cervical ribs and vertebral body formation defect, bifid spinous process, caudal articular process hypoplasia/aplasia and an abnormal sacrum, which may infer they have a different aetiopathogenesis. However, Pug dogs with cervical ribs were more likely to have a transitional thoraco-lumbar vertebra (P = 0.041) and a pre-sacral vertebral count of 26 (P < 0.001). Higher C7/T1 dorsal spinous processes ratios were associated with the presence of cervical ribs (P < 0.001), supporting this is a true homeotic transformation. Relaxation of the stabilizing selection has likely occurred, and the Pug dog appears to be a good naturally occurring model to further investigate the aetiology of cervical ribs, other congenital vertebral anomalies and numerical alterations. © 2018 Anatomical Society.

The acute tendinitis of the longus colli muscle is an unusual diagnosis in the cases of acute dysphagia with cervical pain. Is a self-limiting condition caused by abnormal calcium hydroxyapatite deposition in the prevertebral space and can cause pharyngeal swelling with impaired swallow. It is absolutely critical to make the differential diagnosis with deep cervical infections in order to avoid invasive treatments.

Background. HIV-infected adolescents may be at higher risk for high-grade cervical lesions than HIV-uninfected adolescents. The purpose of this study was to compare the prevalence of high-risk HPV (HR-HPV) infections and Pap smear abnormalities between these two groups. Methods. In this cross-sectional study, we compared the HPV DNA and Pap smear results between 35 HIV-infected and 50 HIV-uninfected adolescents in order to determine the prevalence of HR-HPV genotypes and cervical cytological abnormalities. Comparisons were made using Pearson χ 2 and independent-samples t-tests analyses, and associations between demographic and behavioral characteristics and HPV infections were examined. Results. HIV-infected participants were more likely to be infected with any HPV (88.6% versus 48.0%; P < 0.001) and with at least one HR-HPV (60.0% versus 24.0%; P = 0.001), and to have multiple concurrent HPV infections (68.6% versus 22.0%; P < 0.001). HPV 16 and 18 were relatively underrepresented among HR-HPV infections. Abnormal Pap test results were more common among HIV-infected participants (28.8% versus 12.0%; P = 0.054). A history of smoking was associated with HR-HPV infection. Conclusions. HIV-infected adolescents have an increased risk of infection with HR-HPV and of Pap test abnormalities. The majority of HR-HPV infections among our participants would not be prevented by the currently available vaccinations against HPV. PMID:25389377

Knowledge of cervical human papillomavirus (HPV) status might influence a cytotechnician's assessment of cellular abnormalities. The authors compared original cytotechnicians' Papanicolaou (Pap) readings for which HPV status was concealed with Pap rereads for which HPV status was revealed separately for 3 screening populations. Previously collected cervical Pap smears and clinical data were obtained from the Canadian Cervical Cancer Screening Trial (study A), the Democratic Republic of Congo Community-Based Screening Study (study B), and the Brazilian Investigation into Nutrition and Cervical Cancer Prevention (study C). Smears were reread with knowledge of HPV status for all HPV-positive women as well as a sample of HPV-negative women. Diagnostic performance of Pap cytology was compared between original readings and rereads. A total of 1767 Pap tests were reread. Among 915 rereads for HPV-positive women, the contrast between "revealed" and "concealed" Pap readings demonstrated revisions from negative to positive results for 109 women (cutoff was atypical squamous cells of undetermined significance or worse) and 124 women (cutoff was low-grade squamous intraepithelial lesions [LSIL] or worse). For a disease threshold of cervical intraepithelial neoplasia of grade 2 or worse, specificity significantly declined at the atypical squamous cells of undetermined significance cutoff for studies A (86.6% to 75.3%) and C (42.5% to 15.5%), and at the LSIL cutoff for study C (61.9% to 37.6%). Sensitivity remained nearly unchanged between readings, except in study C, in which reread performance was superior (91.3% vs 71.9% for the LSIL cutoff). A reduction in the diagnostic accuracy of Pap cytology was observed when revealing patients' cervical HPV status, possibly due to a heightened awareness of potential abnormalities, which led to more false-positive results. © 2015 American Cancer Society.

This study aimed to identify factors associated with women's decisions to attend cervical cancer screening and to explore those linked with intention to attend in the coming year and to continue regular screening. A community based case-control study was conducted among woman 30-60 years of age in catchment area of Chatapadung Contracting Medical Unit (CCMU), networking of Khon Kaen Center Hospital, Thailand. Self-administered questionnaires were used to collect data, and in-depth interviews were then performed to explore in greater detail. There were 195 participants. Only one third (32.3 %) had been screened for cervical cancer within the past 5 years. Some 67.7% reported that they had not been screened because they had no abnormal symptoms, single marital status, and no children. Only 10.6% of those never had screening intent to be screened within the next 12 months. High family income (adjusted OR=2.16, 95%CI=1.13-4.14), good attitude towards a Pap test (OR=1.87, 95%CI=1.09-4.23), and having received a recommendation from health care providers were important factors associated with decisions to attend cervical cancer screening (OR=1.73, 95%CI=1.01-4.63). From in-depth interviews, there were five reasons of their decisions to attend cervical cancer screening including yearly check-up, postpartum check-up, having abnormal symptom, encouragement by health care providers, and request from workplace. High family income, good attitude towards a Pap test, and receiving proper recommendation by health care providers, were important factors associated with decision to have cervical cancer screening among women 30-60 years old. Trying to enhance these factors and reduce barriers regarding screening, may increase the coverage rate for cervical cancer screening in Thailand.

The American Society for Colposcopy and Cervical Pathology Colposcopy Standards address the role of and approach to colposcopy and biopsy for cervical cancer prevention in the United States. Working Group 1 was tasked with defining the role of colposcopy, describing benefits and potential harms, and developing an official terminology. A systematic literature review was performed. A national survey of American Society for Colposcopy and Cervical Pathology members provided input on current terminology use. The 2011 International Federation for Cervical Pathology and Colposcopy terminology was used as a template and modified to fit colposcopic practice in the United States. For areas without data, expert consensus guided the recommendation. Draft recommendations were posted online for public comment and presented at an open session of the 2017 International Federation for Cervical Pathology and Colposcopy World Congress for further comment. All comments were considered for the final version. Colposcopy is used in the evaluation of abnormal or inconclusive cervical cancer screening tests. Colposcopy aids the identification of cervical precancers that can be treated, and it allows for conservative management of abnormalities unlikely to progress. The potential harms of colposcopy include pain, psychological distress, and adverse effects of the procedure. A comprehensive colposcopy examination should include documentation of cervix visibility, squamocolumnar junction visibility, presence of acetowhitening, presence of a lesion(s), lesion(s) visibility, size and location of lesions, vascular changes, other features of lesion(s), and colposcopic impression. Minimum criteria for reporting include squamocolumnar junction visibility, presence of acetowhitening, presence of a lesion(s), and colposcopic impression. A recommended terminology for use in US colposcopic practice was developed, with comprehensive and minimal criteria for reporting.

Cervical cancer in women under 25 years of age in Queensland, Australia: To what extent is the diagnosis made by screening cytology?

The current Australian National Cervical Screening Program (NCSP) involves biennial, cytology-based screening of women from the age of 18 years. From December, 2017 this will change to a five-yearly human papilloma virus-based screening commencing at age 25. There is some concern that the new program may delay the opportunistic detection of cervical cancers in women under 25 years. (1) To review all cases of invasive cervical cancer in Queensland women under the age of 25 over the last 28 years. (2) To determine symptoms and screening history prior to diagnosis. A retrospective cohort study was undertaken at the Queensland Centre for Gynaecological Cancer (QCGC) and the Queensland Cancer Registry (QCR) of all women aged between 13 and 25 years diagnosed with cervical cancer in Queensland between 1984 and 2012. Demographic data and symptoms prior to diagnosis were extracted from the QCGC and QCR databases. A total of 56 women aged 13-25, were diagnosed with cervical cancer and treated at the QCGC between 1984 and 2012. The commonest reason for the diagnosis of cancer was investigation of abnormal symptoms (n = 22, 39%) rather than routine Pap smear abnormalities (n = 15, 26%). Consistent with the world literature, there is a very low incidence of cervical cancer in women under 25 years of age, irrespective of the age of commencement of screening, or the screening interval. Our study lends some support to the proposed commencement age of 25 years in the new NCSP. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Relationships among type of parturition, type of discharge from genital tract, involution of cervix, and subsequent reproductive performance in Holstein cows.

Data were from 492 Holstein cows calved between October, 1976, and May, 1977, in eight herds in Michigan. Diameter of the cervix of each cow was estimated by palpation at 8 to 21 days postpartum and again 2 wk later. Parturition and postpartum discharge from the genital tract were classified as normal or abnormal. Size of the cervix between 12 and 26 days postpartum was classified as small, medium, or large within two parity groups. Incidence of abnormal parturition and incidence of abnormal postpartum discharge were 14.1 and 38.0%. Involution of the cervix was affected by parity and type of postpartum discharge. Involution of the cervix occurred sooner postpartum in primiparous than in multiparous cows and sooner postpartum in cows with normal discharge than in cows with abnormal discharge. The greatest difference in cervix diameter between cows with normal or abnormal discharges was 10 mm at 3 wk postpartum. Days from parturition to first detected estrus and first service were extended by abnormal postpartum discharge but not by abnormal parturition. First-service conception rate was lower and days from parturition to conception were higher in cows with medium or large cervices compared to cows with small cervices. Type of postpartum discharge and size of cervix early postpartum may be useful for predicting subsequent reproductive performance in dairy cows.

We used AFM HarmoniX modality to analyse the surface of individual human cervical epithelial cells at three stages of progression to cancer, normal, immortal (pre-malignant) and carcinoma cells. Primary cells from 6 normal strains, 6 cancer, and 6 immortalized lines (derived by plasmid DNA-HPV-16 transfection of cells from 6 healthy individuals) were tested. This cell model allowed for good control of the cell phenotype down to the single cell level, which is impractical to attain in clinical screening tests (ex-vivo). AFM maps of physical (nonspecific) adhesion are collected on fixed dried cells. We show that a surface parameter called fractal dimension can be used to segregate normal from both immortal pre-malignant and malignant cells with sensitivity and specificity of more than 99%. The reported method of analysis can be directly applied to cells collected in liquid cytology screening tests and identified as abnormal with regular optical methods to increase sensitivity. Despite cervical smear screening, sometimes it is very difficult to differentiate cancers cells from pre-malignant cells. By using AFM to analyze the surface properties of human cervical epithelial cells, the authors were able to accurately identify normal from abnormal cells. This method could augment existing protocols to increase diagnostic accuracy. Copyright © 2015. Published by Elsevier Inc.

To describe the treatment of a patient with chronic whiplash-associated disorders (WADs) previously unresponsive to multiple physical therapy and chiropractic treatments, which resolved following Clinical Biomechanics of Posture (CBP) rehabilitation methods. A 40-year-old man involved in a high-speed rear-impact collision developed chronic WADs including cervicothoracic, shoulder, and arm pain and headache. The patient was diagnosed with a confirmed chip fracture of the C5 vertebra and cervical and thoracic disk herniations. He was treated with traditional chiropractic and physical therapy modalities but experienced only temporary symptomatic reduction and was later given a whole body permanent impairment rating of 33% by an orthopedic surgeon. The patient was treated with CBP mirror-image cervical spine adjustments, exercise, and traction to reduce forward head posture and cervical kyphosis. A presentation of abnormal head protrusion resolved and cervical kyphosis returned to lordosis posttreatment. His initial neck disability index was 46% and 0% at the end of care. Verbal pain rating scales also improved for neck pain (from 5/10 to 0/10). A patient with chronic WADs and abnormal head protrusion, cervical kyphosis, and disk herniation experienced an improvement in symptoms and function after the use of CBP rehabilitation protocols when other traditional chiropractic and physical therapy procedures showed little or no lasting improvement.

Introduction. This study sought to investigate potential determinants of patient delay among Moroccan women with cervical cancer. Methods. A cross-sectional study was conducted from June 2014 to June 2015 at the National Institute of Oncology in Rabat. Data were collected using questionnaire among patients with cervical cancer locally advanced or metastatic (stages IIA–IVB). Medical records were abstracted to complete clinical information. An interval longer than 90 days between discovery of initial symptoms and presentation to a provider was defined as a patient delay. Results. Four hundred and one patients with cervical cancer enrolled in this study. The mean age was 52.4 years (SD = 11.5). 53.6% were illiterate. Abnormal vaginal bleeding was identified for 65.8% of patients. 60.1% were diagnosed at stages IIA-IIB. 55.4% were found having patient delay. The regression analyses showed the association between literacy (p < 0.001), distance of the place of the first consultation (p = 0.031), abnormal vaginal bleeding as an earlier symptom (p < 0.001), stage at diagnosis (p < 0.03), knowledge of symptoms (p < 0.001), knowledge of causes (p = 0.008), and practice of gynecological exam during the last three years (p = 0.018) and the patient delay. Conclusion. Educational messages should aim at increasing awareness of cervical cancer, assisting women in symptom recognition, and encouraging earlier presentation. PMID:27882055

Abstract Identifying factors, including human papillomavirus (HPV) genotypes, associated with abnormal anal cytology in HIV-infected women have implications for anal squamous cell cancer (SCC) prevention in HIV-infected women. Anal and cervical samples were collected for cytology, and tested for high-(HR-HPV) and low-risk HPV (LR-HPV) genotypes in a cross-sectional analysis of the IPEC Women's HIV Cohort (Rio de Janeiro, Brazil). Multivariate log-binomial regression models estimated prevalence ratios for factors associated with abnormal anal cytology [≥atypical squamous cells of undetermined significance, (ASC-US)]. Characteristics of the 863 participants included: median age 42 years, 57% non-white, 79% current CD4+ T-cell count >350 cells/mm3, 53% HIV-1 viral load <50 copies/mL, median ART duration 5.8 years. Fifty-one percent of anal specimens contained ≥1 HR-HPV genotype; 31% had abnormal anal cytology [14% ASC-US, 11% low-grade squamous intra-epithelial lesion, (LSIL); 2% atypical squamous cells-cannot exclude high-grade SIL (ASC-H); 4% high-grade SIL/cancer (HSIL+)]. In multivariate analysis, cervical LSIL+, nadir CD4+ T-cell count ≤50 cells/mm3, HIV-1 viral load ≥50 copies/mL, and anal HPV 6, 11, 16, 18, 33, 45, 52, 56, and 58 were associated with ≥anal ASC-US (p<0.05). Abnormal anal cytology and HR-HPV prevalences were high. HIV-infected women with cervical LSIL+, low nadir CD4+ counts, or detectable HIV-1 viral loads should be a particular focus for enhanced anal SCC screening efforts. PMID:25361401

As part of the Patient Navigation Research Program, we examined the effect of patient navigation versus usual care on timely diagnostic follow-up, defined as clinical management for women with cervical abnormalities within accepted time frames. Participants from four Patient Navigation Research Program centers were divided into low- and high-risk abnormality groups and analyzed separately. Low-risk participants (n = 2088) were those who enrolled with an initial Pap test finding of atypical squamous cells of undetermined significance (ASCUS) with a positive high-risk human papillomavirus (HPV) serotype, atypical glandular cells, or low-grade squamous intraepithelial lesion (LGSIL). High-risk participants were those with an initial finding of high-grade squamous intraepithelial lesion (HGSIL) (n = 229). A dichotomous outcome of timely diagnostic follow-up within 180 days was used for the low-risk abnormality group and timely diagnostic follow-up within 60 days for the high-risk group, consistent with treatment guidelines. A logistic mixed-effects regression model was used to evaluate the intervention effect using a random effect for study arm within an institution. A backward selection process was used for multivariable model building, considering the impact of each predictor on the intervention effect. Low-risk women in the patient navigation arm showed an improvement in the odds of timely diagnostic follow-up across all racial groups, but statistically significant effects were only observed in non-English-speaking Hispanics (OR 5.88, 95% CI 2.81-12.29). No effect was observed among high-risk women. These results suggest that patient navigation can improve timely diagnostic follow-up among women with low-risk cervical abnormalities, particularly in non-English-speaking Hispanic women.

There is a need for controlled studies to assess the impact of patient navigation in vulnerable cancer populations. Boston Patient Navigation Research Program conducted a quasi-experimental patient navigation intervention across six federally qualified inner-city community health centers, three assigned to a breast cancer navigation intervention and three assigned to a cervical cancer navigation intervention; each group then served as the control for the other. Eligible women had an abnormal breast or cervical cancer screening test conducted at one of the participating health centers during a baseline (2004-2005) or intervention period (2007-2008). Kaplan-Meier survival curves and proportional hazards regression examined the effect of patient navigation on time to definitive diagnosis, adjusting for covariates, clustering by clinic and differences between the baseline and intervention period. We enrolled 997 subjects in the baseline period and 3,041 subjects during the intervention period, of whom 1,497 were in the navigated arm, and 1,544 in the control arm. There was a significant decrease in time to diagnosis for subjects in the navigated group compared with controls among those with a cervical screening abnormality [aHR 1.46; 95% confidence interval (CI), 1.1-1.9]; and among those with a breast cancer screening abnormality that resolved after 60 days (aHR 1.40; 95% CI, 1.1-1.9), with no differences before 60 days. This study documents a benefit of patient navigation on time to diagnosis among a racially/ethnically diverse inner city population. Patient navigation may address cancer health disparities by reducing time to diagnosis following an abnormal cancer-screening event. 2012 AACR

To perform an audit of all smears reported as atypical glandular cells (AGC) using the Bethesda system (TBS) 2001. A total of 18 376 cervical smears were screened from January 2005 to June 2007, of which 65 cases were reported as AGC. Follow-up histology was available in 31 cases (47.7%), in whom a detailed cytological/histological correlation was carried out. AGC constituted 0.35% of all Pap smears. Follow-up histology was normal or benign in 20 cases, whereas a squamous or glandular abnormality was seen in 11 cases. Squamous abnormalities included one case each of cervical intraepithelial neoplasia (CIN)1, CIN2 and CIN3 and five cases of squamous cell carcinoma. All glandular epithelial abnormalities were endometrial in origin and included two endometrial adenocarcinomas and one uterine serous carcinoma. Neither in situ nor invasive adenocarcinoma of the endocervix was observed. Review of smears and reclassification as AGC, not otherwise specified and favour neoplasia revealed a higher proportion of abnormality in the latter group, reaffirming the utility of subtyping. The median age of women with AGC was 41 years. The outcome was analysed with respect to the median age. In women aged equal or more than 40 years, AGC reflected a high-grade squamous or glandular epithelial abnormality in 50% of cases compared with none in those less than 40 years old (P = 0.010). The age of the woman as well as the subtype of atypical glandular cells influences outcome and hence must be taken into consideration while formulating an acceptable management strategy in these women in a low-resource setting.

Classification and Management of Pediatric Subaxial Cervical Spine Injuries.

PubMed

Madura, Casey J; Johnston, James M

2017-01-01

Appropriate management of subaxial spine injury in children requires an appreciation for the differences in anatomy, biomechanics, injury patterns, and treatment options compared with adult patients. Increased flexibility, weak neck muscles, and cranial disproportion predispose younger children to upper cervical injuries and spinal cord injury without radiographic abnormality. A majority of subaxial cervical spine injuries can be treated nonoperatively. Surgical instrumentation options for children have significantly increased in recent years. Future studies of outcomes for children with subaxial cervical spine injury should focus on injury classification and standardized outcome measures to ensure continued improvement in quality of care for this patient population.

Abnormalities in the somatosensory system are increasingly being recognized in patients with dystonia. The aim of this study was to investigate whether sensory abnormalities are confined to the dystonic body segments or whether there is a wider involvement in patients with idiopathic dystonia. For this purpose, we recruited 20 patients, 8 had generalized, 5 had segmental dystonia with upper extremity involvement, and 7 had cervical dystonia. In total, there were 13 patients with upper extremity involvement. We used Quantitative Sensory Testing (QST) at the back of the hand in all patients and at the shoulder in patients with cervical dystonia. The main finding on the hand QST was impaired cold detection threshold (CDT), dynamic mechanical allodynia (DMA), and thermal sensory limen (TSL). The alterations were present on both hands, but more pronounced on the side more affected with dystonia. Patients with cervical dystonia showed a reduced CDT and hot detection threshold (HDT), enhanced TSL and DMA at the back of the hand, whereas the shoulder QST only revealed increased cold pain threshold and DMA. In summary, QST clearly shows distinct sensory abnormalities in patients with idiopathic dystonia, which may also manifest in body regions without evident dystonia. Further studies with larger groups of dystonia patients are needed to prove the consistency of these findings.

Is there a correlation between sleep disordered breathing and foramen magnum stenosis in children with achondroplasia?

Children with achondroplasia have midface hypoplasia, frontal bossing, spinal stenosis, rhizomelia, and a small foramen magnum. Central sleep apnea, with potential resultant sudden death, is thought to be related to compression of the spinal cord at the cervicomedullary junction in these patients. Screening polysomnography and/or cervical spine MRI are often performed for infants with achondroplasia. Decompressive suboccipital craniectomy has been performed in selected cases. We aim to better delineate the relationship between polysomnography, cervical spine MRI, and indications for surgical decompression in achondroplasia.We retrospectively review electronic medical records of all children with achondroplasia in our IRB-approved skeletal dysplasia registry who had received screening polysomnography and cervical spine MRI examination was performed. We explored correlations of polysomnography, MRI parameters, and need for decompressive surgery. Seventeen patients with both polysomnography and MRI of the cervical spine met inclusion criteria. The average age at time of the sleep study was 2.4 ± 3.6 years. An abnormal apnea-hypopnea index was found in all patients, with central sleep apnea found in 6/17. Five patients (29%) required foramen magnum decompression. We found no statistically significant correlation between central sleep apnea and abnormal MRI findings suggestive of foramen magnum stenosis. Screening polysomnography is an important tool but does not appear to correlate with MRI findings of foramen magnum stenosis. Cord compression, with either associated T2 cord signal abnormality or clinical findings of clonus, was most predictive of subsequent surgical decompression. © 2015 Wiley Periodicals, Inc.

A feature common to all congenital or inflammatory abnormalities of the cervical spine is an actual or potential reduction in the lumen of the spinal canal. The spinal cord and nerve roots are at risk. During intubation, and positioning the patient on the table, all untoward movements of the cervical spine may lead to spinal cord compression. Abnormalities of the cervical spine carry the risk of a difficult intubation. If there is much debate as to what constitutes optimum management of the airway, there is no evidence that any one method is the best. Recognizing the possible instability and intubating with care, are probably much more important in preserving neurological function than any particular mode of intubation. During maintenance of anaesthesia, the main goal is to preserve adequate spinal cord perfusion in order to prevent further damage. Spinal cord blood flow seems to be regulated by the same factors as cerebral blood flow. Hypercapnia increases cord blood flow while hypocapnia decreases it. Therefore, normocapnia or mild hypocapnia is recommended. Induced hypotension is frequently used to decrease blood loss. However, in patients with a marginally perfused spinal cord, the reduction in blood flow may cause ischaemia of the spinal cord and may therefore be relatively contraindicated. In addition to standard intraoperative monitoring, spinal cord monitoring is almost mandatory. Monitoring somatosensory evoked potentials is used routinely. However, the major limitation is that this technique only monitors dorsal column function; theoretically, motor paralysis can occur despite a lack of change in recorded signals. Neurogenic motor evoked potentials may now be used to monitor anterior spinal cord integrity.(ABSTRACT TRUNCATED AT 250 WORDS)

In April 2014 we investigated the association of migration of a woman's husband with her high-risk human papillomavirus (HR-HPV) infection status and her abnormal cervical cytology status in the Achham district of rural Far-Western Nepal. Women were surveyed and screened for HR-HPV during a health camp conducted by the Nepal Fertility Care Center. Univariate and multivariable statistical tests were performed to determine the association of a husband's migration status with HR-HPV infection and cervical cytology status. In 265 women, the prevalence of HR-HPV was 7.5% (20/265), while the prevalence of abnormal cervical cytology, defined using the Bethesda system as atypical glandular cells of undetermined significance or worse, was 7.6% (19/251). Half of the study participants (50.8%, 130/256) had husbands who had reported migrating for work at least once. Women aged ≤34 years were significantly less likely to test positive for HR-HPV than women aged >34 years (OR 0.22, 95% CI 0.07 to 0.71). HR-HPV infection and abnormal cervical cytology status were not directly associated with a husband's migration. Older women were found to have a higher prevalence of HPV than younger women. It is possible that a husband's migration for work could be delaying HR-HPV infections in married women until an older age. © The Author 2016.

Rates of abnormalities and infectious agents in cervical smears from female inmates in Texas: comparison with private and university clinic patients.

PubMed

Logrono, R; Wong, J Y

1999-09-01

Inmates are generally considered a high-risk population for gynecologic neoplasia and sexually transmitted diseases. Cervical smears from prisoners of the Texas Department of Corrections (TDC) were expected initially to have higher rates of cellular abnormalities and infectious agents than do smears from the general population. The cytologic findings from 25,522 TDC gynecologic smears were compared with those of 6883 cases from The University of Texas Medical Branch (UTMB) affiliated physician private clinics, and with 56,178 from the UTMB hospital clinics. The period of study was from September 1995 to February 1998. This study revealed a 5.23% higher rate of abnormalities for TDC gynecologic smears as compared with that for the private clinic smears. However, the TDC rate of abnormalities was unexpectedly 1.08% lower than that for the UTMB clinic smears. These unexpected findings were probably the result of a more selected high-risk population referred to the UTMB clinics. The TDC smears showed also the highest incidence of trichomoniasis.

Personality disorders as maladaptive, extreme variants of normal personality: borderline personality disorder and neuroticism in a substance using sample.

2013-10-01

Although the current diagnostic manual conceptualizes personality disorders (PDs) as categorical entities, an alternative perspective is that PDs represent maladaptive extreme versions of the same traits that describe normal personality. Existing evidence indicates that normal personality traits, such as those assessed by the five-factor model (FFM), share a common structure and obtain reasonably predictable correlations with the PDs. However, very little research has investigated whether PDs are more extreme than normal personality traits. Utilizing item-response theory analyses, the authors of the current study extend previous research to demonstrate that the diagnostic criterion for borderline personality disorder and FFM neuroticism could be fit along a single latent dimension. Furthermore, the authors' findings indicate that the borderline criteria assessed the shared latent trait at a level that was more extreme (d = 1.11) than FFM neuroticism. This finding provides further evidence for dimensional understanding of personality pathology and suggests that a trait model in DSM-5 should span normal and abnormal personality functioning, but focus on the extremes of these common traits.

Analysis of cervical ribs in a series of human fetuses

In humans, an increasing body of evidence has linked the frequency of cervical ribs to stillbirths, other malformations and early childhood cancers. However, the frequency of cervical ribs in a putatively healthy fetal population is not sufficiently known to assess the actual medical risks of these prenatal findings. We therefore analyzed the presence of skeletal anomalies in a series of 199 electively aborted fetuses, which were whole-mount stained with alizarin red specific for skeletal tissues. Results show that approximately 40% of the fetuses had cervical ribs, even though external congenital abnormalities such as craniofacial and limb defects were absent. A literature overview indicates that the observed frequency of cervical ribs is comparable to results previously obtained for deceased fetuses with no or minor congenital anomalies, and higher than expected for healthy fetuses. This unexpected result can probably in part be explained by a higher detection rate of small cervical ribs when using alizarin red staining instead of radiographs. Additionally, studies in the literature suggest that the size of a cervical rib may indicate the severity of abnormalities, but this possibility requires further research. Anomalies of the axial skeleton are known to be caused by a disturbance of early development, which alters Hox gene expression, but in this study the origin of the stress could not be verified as maternal medical data were not available. The co-occurrence of rudimentary or absent 12th ribs in 23.6% of the cases with cervical ribs indicates that in approximately 8% of the fetuses a homeotic shift occurred over a larger part of the vertebral column. This suggests that the expression of multiple Hox genes may have been affected in these fetuses. Together, the high incidence of cervical ribs and also their co-occurrence with rudimentary or absent 12th ribs suggests that there may have been a disturbance of early development such that the studied fetuses are probably not informative about the general population. Future studies determining the frequency of cervical ribs in a more healthy fetal population are therefore needed to evaluate their potential as an indicator of medical risks. PMID:21689099

Objective The rates of participation in the Korean nationwide cervical cancer screening program and the rates of abnormal test results were determined. Methods The database of the National Health Insurance Service (NHIS) was used during the study period (2009–2014). Results The participation rate increased from 41.10% in 2009 to 51.52% in 2014 (annual percentage change, 4.126%; 95% confidence interval [CI]=2.253–6.034). During the study period, women ≥70 years of age had the lowest rate of participation (range, 21.7%–31.9%) and those 30–39 years of age the second-lowest (27.7%–44.9%). The participation rates of National Health Insurance beneficiaries (range, 48.6%–52.5%) were higher than those of Medical Aid Program (MAP) recipients (29.6%–33.2%). The rates of abnormal results were 0.65% in 2009 and 0.52% in 2014, with a decreasing tendency in all age groups except the youngest (30–39 years). Every year the abnormal result rates tended to decrease with age, from the age groups of 30–39 years to 60–69 years but increased in women ≥70 years of age. The ratio of patients with atypical squamous cells of undetermined significance compared with those with squamous intraepithelial lesions increased from 2.71 in 2009 to 4.91 in 2014. Conclusion Differences related to age and occurring over time were found in the rates of participation and abnormal results. Further efforts are needed to encourage participation in cervical cancer screening, especially for MAP recipients, elderly women and women 30–39 years of age. Quality control measures for cervical cancer screening programs should be enforced consistently. PMID:28657224

Disparities in cancer incidence and mortality rates between regions arise due to differences in socioeconomic conditions and in human development factors. The major purpose of this study was to measure the role of the Human Development Index (HDI) in the pattern of cervical cytological abnormalities (CCAs). This was an analytical sectional study involving a review of secondary cervical cytology data collected from women living in the state of Maranhão, Brazil, in 2007-2012 and collected from the Cervical Cancer Information System (Sistema de Informação do Câncer do Colo do Útero - SISCOLO). The cervical screening results were classified according to the Brazilian Classification of Cervical Reporting (Nomenclatura Brasileira para Laudos Cervicais), an adaptation of the Bethesda System. The Municipal Human Development Index (MHDI) was used, which is an adaptation of the global HDI. The association between CCAs and MHDI was evaluated using the chi-squared test and odds ratios (ORs) with 95 % confidence intervals (95 % CI). The significance level used for all tests was 5 %. We analysed 1,363,689 examinations of women living in the state of Maranhão. CCAs were identified in 2.0 % of smears in municipalities with high MHDI, 2.2 % in those with medium or low MHDI and 4.1 % in those with very low MHDI. In addition, potentially malignant changes and suspected cervical cancer (HSIL+) were 40.0 % more frequent (0.3 %) in municipalities with medium or low MHDI and 3.6 times more frequent (0.8 %) in municipalities with very low MHDI compared to those with high MHDI (0.2 %). The association between MHDI and the occurrence of CCAs and HSIL+ shows that more developed areas with more effective health services have a lower prevalence of these lesions. To control cervical cancer, it is necessary to reduce social inequality and improve the availability of health services.

The success of cervical screening relies on women with abnormal cervical cytology attending for follow-up by colposcopy and related procedures. Failure to attend for colposcopy, however, is a common problem in many countries. The objective of this study was to identify factors associated with non-attendance at an initial colposcopy examination among women with low-grade abnormal cervical cytology. A cohort study was conducted within one arm of a multi-centre population-based randomised controlled trial nested within the UK NHS Cervical Screening Programmes. The trial recruited women aged 20-59 years with recent low-grade cervical cytology; women randomised to immediate referral for colposcopy were included in the current analysis (n=2213). At trial recruitment, women completed a socio-demographic and lifestyle questionnaire; 1693 women in the colposcopy arm were also invited to complete a psychosocial questionnaire, including the Hospital Anxiety and Depression Scale. Women were sent up to two colposcopy appointments. A telephone number was provided to reschedule if necessary. Defaulters were defined as those who failed to attend after two appointments. Logistic regression methods were used to compute multivariate odds ratios (OR) to identify variables significantly associated with default. 148 women defaulted (6.7%, 95%CI 5.7-7.8%). In multivariate analysis, risk of default was significantly raised in those not in paid employment (OR=2.70, 95%CI 1.64-4.43) and current smokers (OR=1.62, 95%CI 1.12-2.34). Default risk deceased with increasing age and level of post-school education/training and was lower in women with children (OR=0.59, 95%CI 0.35-0.98). Among the sub-group invited to complete psychosocial questionnaires, women who were not worried about having cervical cancer were significantly more likely to default (multivariate OR=1.56, 95%CI 1.04-2.35). Anxiety and depression were not significantly associated with default. Women at highest risk of default from colposcopy are younger, not in paid employment, smoke, lack post-school education, have not had children and are not worried about having cervical cancer. Findings such as these could inform the development of tools to predict the likelihood that an individual woman will default from follow-up. Interventions to minimise default also deserve consideration, but a better understanding of reasons for default is needed to inform intervention development. Copyright © 2012.

Aims To evaluate changes in QT duration during low-dose haloperidol use, and determine associations between clinical variables and potentially dangerous QT prolongation. Methods In a retrospective cohort study in a tertiary university teaching hospital in The Netherlands, all 1788 patients receiving haloperidol between 2005 and 2007 were studied; ninety-seven were suitable for final analysis. Rate-corrected QT duration (QTc) was measured before, during and after haloperidol use. Clinical variables before haloperidol use and at the time of each ECG recording were retrieved from hospital charts. Mixed model analysis was used to estimate changes in QT duration. Risk factors for potentially dangerous QT prolongation were estimated by logistic regression analysis. Results Patients with normal before-haloperidol QTc duration (male ≤430 ms, female ≤450 ms) had a significant increase in QTc duration of 23 ms during haloperidol use; twenty-three percent of patients rose to abnormal levels (male ≥450 ms, female ≥470 ms). In contrast, a significant decrease occurred in patients with borderline (male 430–450 ms, female 450–470 ms) or abnormal before-haloperidol QTc duration (15 ms and 46 ms, respectively); twenty-three percent of patients in the borderline group, and only 9% of patients in the abnormal group obtained abnormal levels. Potentially dangerous QTc prolongation was independently associated with surgery before haloperidol use (ORadj 34.9, p = 0.009) and before-haloperidol QTc duration (ORadj 0.94, p = 0.004). Conclusion QTc duration during haloperidol use changes differentially, increasing in patients with normal before-haloperidol QTc duration, but decreasing in patients with prolonged before-haloperidol QTc duration. Shorter before-haloperidol QTc duration and surgery before haloperidol use predict potentially dangerous QTc prolongation. PMID:21961030

CORRELATION OF CERVICAL LORDOSIS MEASUREMENT WITH INCIDENCE OF MOTOR VEHICLE ACCIDENTS

PubMed Central

Marshall, Dorothy L.; Tuchin, Peter J.

1996-01-01

A retrospective analysis of 500 patient radiographs was conducted to measure the clinical correlation of cervical lordosis measurements and incidence of motor vehicle accident (MVA). Five hundred lateral cervical radiographs were selected at random from the practice of one of the authors (DLM). The C1-7 angle of the cervical curve was then measured by two blinded examiners. Inter-examiner reliability had a confidence interval of 95%. Eighty-two percent of patients who have had a MVA had an abnormal lordosis. The mean lordosis of patients who had been involved in a MVA was 26.1 degrees (SD 11.4), compared with 36.4 (SD 8.4) for those who had not been involved in a MVA. The results suggest a correlation of reduced cervical lordosis measurements following motor vehicle accident (MVA). PMID:17987143

Prevalence and cumulative incidence of abnormal cervical cytology among HIV-infected Thai women: a 5.5-year retrospective cohort study

PubMed Central

2011-01-01

Background Cervical cancer is one of the most common AIDS-related malignancies in Thailand. To prevent cervical cancer, The US Public Health Service and The Infectious Disease Society of America have recommended that all HIV-infected women should obtain 2 Pap smears 6 months apart after the initial HIV diagnosis and, if results of both are normal, should undergo annual cytological screening. However, there has been no evidence in supporting whether this guideline is appropriate in all settings - especially in areas where HIV-infected women are living in resource-constrained condition. Methods To determine the appropriate interval of Pap smear screenings for HIV-infected Thai women and risk factors for subsequent abnormal cervical cytology, we assessed the prevalence, cumulative incidence and associated factors of cervical cell abnormalities (atypical squamous cell of undetermined significance or higher grades, ASCUS+) among this group of patients. Results The prevalence of ASCUS+ was 15.4% at the first visit, and the cumulative incidence of ASCUS+ gradually increased to 37% in the first 3.5 years of follow-up appointments (first 7 times), and tended to plateau in the last 2 years. For multivariate correlation analysis, women with a CD4 count <350 cells/μL had a significant correlation with ASCUS+ (P = 0.043). There were no associations of subsequent ASCUS+ with age, pregnancy, contraceptive method, highly active anti-retroviral treatment, assumed duration of infection, or the CD4 count nadir level. Conclusion There are high prevalence and cumulative incidence of ASCUS+ in HIV-infected Thai women. With a high lost-to-follow-up rate, an appropriate interval of Pap smear screening cannot be concluded from the present study. Nevertheless, the HIV-infected Thai women may require more than two normal semi-annual Pap smears before shifting to routinely annual cytologic screening. PMID:21211065

Psychobiology and treatment of borderline personality disorder.

PubMed

Cloninger, C Robert

2002-04-01

Borderline personality disorder can be characterized in terms of a profile of abnormal deviations on multiple personality dimensions using the temperament and character inventory (TCI). Borderline patients show poor character development, including low TCI self-directedness (irresponsible, blaming) and low TCI cooperativeness (hostile, intolerant). Their temperament is explosive or unstable due to a combination of high TCI harm avoidance (anxious, shy), high TCI novelty seeking (impulsive, quick-tempered), and low reward dependence (cold, aloof). Consequently they are usually dysthymic with an admixture of anxiety and anger, and regulate their social problems and intense emotions in immature ways. Genetic and psychobiological studies have led to identification of biological correlates of each of the TCI dimensions of personality, including individual differences in regional brain activity, psychophysiological variables, neuroendocrine abnormalities and specific gene polymorphisms. Each dimension of personality involves complex non-linear interaction of multiple genetic and environmental factors and, in turn, each personality dimension interacts with the others in influencing the way an individual directs and adapts to his or her life experiences. Systematic clinical trials have shown that these personality variables predict the response to pharmacological and psychotherapeutic treatments. For example, high harm avoidance and low self-directedness predict slower response and more rapid relapse with both antidepressants and cognitive-behavioral therapy. Treatment with drugs and/or psychotherapy can be individually matched to the patient's profile of temperament and character traits, rather than treating a heterogeneous group of patients as if they had a discrete, homogeneous illness. Fundamental change in cognitive schemas depends on attention to all aspects of character, especially self-transcendence, which has previously been neglected in cognitive-behavioral therapy. Personality integration requires non-resistance to our natural intuitive awareness, rather than intensified intellectual and emotional defenses.

An analysis of the change in strain distribution of intervertebral discs present after anterior cervical decompression and fusion by an original method. The analytical results were compared to occurrence of herniation of the intervertebral disc on magnetic resonance imaging. To elucidate the influence of anterior cervical decompression and fusion on the unfused segments of the spine. There is no consensus regarding the exact significance of the biomechanical change in the unfused segment present after surgery. Ninety-six patients subjected to anterior cervical decompression and fusion for herniation of intervertebral discs were examined. Shear strain and longitudinal strain of intervertebral discs were analyzed on pre- and postoperative lateral dynamic routine radiography of the cervical spine. Thirty of the 96 patients were examined by magnetic resonance imaging before and after surgery, and the relation between alteration in strains and postsurgical occurrence of disc herniation was examined. In the cases of double- or triple-level fusion, shear strain of adjacent segments had increased 20% on average 1 year after surgery. Thirteen intervertebral discs that had an abnormally high degree of strain showed an increase in longitudinal strain after surgery. Eleven (85%) of the 13 discs that showed an abnormal increase in longitudinal strain had herniation in the same intervertebral discs with compression of the spinal cord during the follow-up period. Relief of symptoms was significantly poor in the patients with recent herniation. Close attention should be paid to long-term biomechanical changes in the unfused segment.

To compare symptoms in patients with physiologic postconcussion disorder (PCD) versus cervicogenic/vestibular PCD. We hypothesized that most symptoms would not be equivalent. In particular, we hypothesized that cognitive symptoms would be more often associated with physiologic PCD. Retrospective review of symptom reports from patients who completed a 22-item symptom questionnaire. University-based concussion clinic. Convenience sample of 128 patients who had symptoms after head injury for more than 3 weeks and who had provocative treadmill exercise testing. Subjects were classified as either physiologic PCD (abnormal treadmill performance and a normal cervical/vestibular physical examination) or cervicogenic/vestibular PCD (CGV, normal treadmill performance, and an abnormal cervical/vestibular physical examination). Self-reported symptoms. Univariate and multivariate methods, including t tests, tests of equivalence, a logistic regression model, k-nearest neighbor analysis, multidimensional scaling, and principle components analysis were used to see whether symptoms could distinguish PCD from CGV. None of the statistical methods used to analyze self-reported symptoms was able to adequately distinguish patients with PCD from patients with CGV. Symptoms after head injury, including cognitive symptoms, have traditionally been ascribed to brain injury, but they do not reliably discriminate between physiologic PCD and cervicogenic/vestibular PCD. Clinicians should consider specific testing of exercise tolerance and perform a physical examination of the cervical spine and the vestibular/ocular systems to determine the etiology of postconcussion symptoms. Symptoms after head injury, including cognitive symptoms, do not discriminate between concussion and cervical/vestibular injury.

Prospective study of swallowing function in patients with cervical dystonia undergoing selective peripheral denervation

OBJECTIVE—To characterise swallowing function in patients with cervical dystonia with botulinum toxin treatment failure, before and after selective peripheral denervation surgery.
METHODS—Twelve patients with cervical dystonia had a thorough examination including standardised assessment for cervical dystonia, scoring of subjective dysphagia, and videofluoroscopic swallow. Videofluoroscopy was scored by consensus opinion between a speech and language therapist and an independent blinded radiologist using a validated scoring system.
RESULTS—Seven patients with cervical dystonia experienced no subjective dysphagia either before or after surgery, although in all these patients there was objective videofluoroscopic evidence of underlying mild to moderate oropharyngeal dysphagia preoperatively and postoperatively. The most common finding was delayed initiation of swallow. Three other patients, also without subjective dysphagia before surgery, developed postoperative dysphagia. In these patients, videofluoroscopy showed a delayed swallow reflex before surgery, which was worse postoperatively in two. The remaining two patients had mild subjective dysphagia before surgery that improved postoperatively in one and deteriorated in the other. In the first, videofluoroscopy was normal preoperatively and postoperatively, and in the second, oral bolus preparation was moderately abnormal preoperatively and swallow initiation was delayed postoperatively. Mean subjective dysphagia scores did not change significantly. Apart from a significant improvement of tongue base retraction, videofluoroscopic scores were not significantly different after surgery. Postoperatively there was significant improvement of overall cervical dystonia severity and abnormal head rotation in the group as a whole. There was no correlation between age, duration of symptoms of cervical dystonia, preoperative or postoperative cervical dystonia severity, subjective dysphagia scores, or videofluoroscopic scores. However, in the five patients with persisting anterior sagittal head shift as part of the torticollis, tongue base retraction was less likely to improve after surgery compared with those without head shift.
CONCLUSION—Surgical denervation of dystonic neck muscles, leading to improved neck posture, can also improve tongue base retraction, which is a key component of normal bolus propagation. However, delayed swallow initiation, a common feature in patients with cervical dystonia, can be further compromised by surgery, leading to subjective dysphagia. In general, selective peripheral denervation seems to be a safe procedure with no major compromise of swallowing function.

The movements of the cervical spine during head rotation are too complicated to measure using conventional radiography or computed tomography (CT) techniques. In this study, we measure three-dimensional segmental motion of cervical spine rotation in vivo using a non-invasive measurement technique. Sixteen healthy volunteers underwent three-dimensional CT of the cervical spine during head rotation. Occiput (Oc) - T1 reconstructions were created of volunteers in each of 3 positions: supine and maximum left and right rotations of the head with respect to the bosom. Segmental motions were calculated using Euler angles and volume merge methods in three major planes. Mean maximum axial rotation of the cervical spine to one side was 1.6° to 38.5° at each level. Coupled lateral bending opposite to lateral bending was observed in the upper cervical levels, while in the subaxial cervical levels, it was observed in the same direction as axial rotation. Coupled extension was observed in the cervical levels of C5-T1, while coupled flexion was observed in the cervical levels of Oc-C5. The three-dimensional cervical segmental motions in rotation were accurately measured with the non-invasive measure. These findings will be helpful as the basis for understanding cervical spine movement in rotation and abnormal conditions. The presented data also provide baseline segmental motions for the design of prostheses for the cervical spine.

We compare the electrodiagnostic (EDX) yield of limb muscles in revealing lower motor neuron (LMN) dysfunction by electromyography (EMG) in early stage amyotrophic lateral sclerosis (ALS). Single-site retrospective review Results: This study includes 122 consecutive patients with possible ALS as defined by revised El Escorial Criteria. Distal limb muscles show more frequent EMG abnormalities than proximal muscles. EDX yield is higher in the limb where weakness begins and when clinical signs of LMN dysfunction are evident. Adoption of Awaji criteria increases the yield of EMG positive segments significantly in the cervical (p<0.0005) and lumbosacral regions (P<0.0001), and upgrades 19 patients into probable and 1 patient into definite categories. Electromyographic abnormalities are distal limb-predominant in early stage ALS. A redefinition of an EDX-positive cervical or lumbosacral segment, with an emphasis on distal limb muscles, may result in an earlier ALS diagnosis. This article is protected by copyright.

The aim of the study was to estimate the risk of high-grade cervical and vaginal intraepithelial neoplasia (CIN/VAIN 2+) and cancer among women treated surgically for high-grade vulvar intraepithelial neoplasia (HGVIN) and vulvar cancer. We performed a retrospective cohort study of women who underwent surgery for HGVIN/vulvar cancer between 2006 and 2010. Univariate and multivariate analyses using stepwise selection were used to identify correlates of abnormal cytology after treatment for VIN and vulvar cancer. Among 191 women under surveillance for a median of 3.7 years who underwent treatment for HGVIN/vulvar cancer, primary vulvar lesions included VIN 2 (10, 5%), VIN 3 (102, 53%), and carcinoma (79, 41%). During follow-up, 71 (37%) had abnormal cytology, including 47 (25%) low grade, 23 (12%) high grade, and 1 (0.5%) carcinoma. Subsequent risk for VAIN 2+ was 11% (6/57) after previous hysterectomy and 8% for CIN 2+ (10/124) with intact cervix. Overall risk for CIN 3+ was 5%. Correlates of high-grade cytology after treatment for HGVIN/vulvar cancer included nonwhite race (odds ratio [OR] = 3.3, 95% CI = 1.50-7.36), immunodeficiency (OR = 4.2, 95% CI = 1.76-9.94), and previous abnormal cytology (OR = 2.7, 95% CI = 1.29-5.78). Stepwise multivariate analysis revealed immunosuppression as the only significant correlate of high-grade cytology after vulvar treatment (adjusted OR = 3.7, 95% CI = 1.26-10.83). Women with HGVIN/cancer should have cervical/vaginal cytology before vulvar surgery. Those with a negative cervical or vaginal cytology result should undergo cytology testing at 1- to 3-year intervals, based on the threshold for CIN 3+ set forth by the American Society for Colposcopy and Cervical Pathology.

There is a need for reliable, automated high throughput HPV detection and genotyping methods for pre- and post-prophylactic vaccine intervention analyses. To optimize the linear array (LA) HPV genotyping test (Roche Diagnostics, Rotkreuz) in regard to possible automation steps for the routine laboratory diagnosis of HPV infections and to analyze the HPV genotype distribution in cervical specimens of women without cytological abnormalities in Switzerland. 680 cervical cell specimens with normal cytology, obtained from women undergoing routine cervical screening by liquid-based Pap smear, were analyzed by the LA HPV genotyping test for HPV-DNA. The automation of the LA HPV genotyping test resulted in a total hands-on time reduction of 255 min (from 480 to 225 min; 53%). Any of 37 HPV genotypes were detected in 117 (17.2%) and high-risk (HR) HPV in 55 (8.1%) of 680 women with normal cytology. The highest prevalence of any HPV (28.1%) and HR-HPV (15.1%) was observed in age-group 21-30 and showed a continuous decrease in older age-groups. The most common HR-HPV genotypes were HPV-16 (12%), HPV-31 (9.4%), HPV-52 (6%), HPV-51 (5.1%), HPV-45 (4.3%), HPV-58 (4.3%) and HPV-59 (4.3%). The optimization and automation of the LA HPV genotyping test makes it suited for high throughput HPV detection and typing. The epidemiological data provides information about distribution of HPV genotypes in women without cytological abnormalities in Switzerland and may be important for determining the future impact of vaccines and potential changes in the country's epidemiological HPV profile.

The quality of cervicovaginal smears determines the success of cytology in screening programs for cervical cancer. Bethesda 2014 revisited the adequacy criteria for atrophic smears and redefined the squamous cell count in the "unsatisfactory" category. In this study, we evaluated the smear quality of Thinprep liquid-based cervicovaginal Papanicolaou cytology slides (TPS) that were previously deemed unsatisfactory, to determine reasons for such categorization. In addition, we attempted to establish the impact of the new adequacy criteria on the rate and management of unsatisfactory diagnosis. About 234 unsatisfactory TPS were examined. The reasons for unsatisfactory were noted. The number of squamous cells was recounted, as per the new Bethesda criteria, in borderline adequacy cases that showed an atrophic pattern. The leading cause for unsatisfactory TPS was lubricating gel, followed by blood, as observed in older and younger age groups, respectively (Figure 1). Eleven borderline cases were reclassified as "satisfactory" using the new Bethesda cell count, with 27% above 60 years of age. About 82% of these borderline cases were negative for intraepithelial lesion or malignancy on repeat testing. There was no difference of management or change in rate of unsatisfactory when patients above 60 were reclassified into the satisfactory category using the new Bethesda count. However, a larger study is needed to evaluate whether the new recommendation for minimum cellularity can be implemented in patients above a certain age cut-off. The study highlights the need for improvement in collection practices and education of practitioners. © 2017 Wiley Periodicals, Inc.

The relatively high incidence of cervical cancer in women at older ages is a continuing concern in countries with long-established cervical screening. Controversy remains on when and how to cease screening. Existing population-based studies on the effectiveness of cervical screening at older ages have not considered women's screening history. We performed a nationwide cohort study to investigate the incidence of cervical cancer after age 60 years and its association with cervical screening at age 61-65, stratified by screening history at age 51-60. Using the Total Population Register, we identified 569,132 women born between 1 January 1919 and 31 December 1945, resident in Sweden since age 51. Women's cytological screening records, cervical cancer occurrence, and FIGO stage (for those diagnosed with cancer) were retrieved from national registers and medical charts. We calculated the cumulative incidence of cervical cancer from age 61 to age 80 using a survival function considering competing risk, and estimated the hazard ratio (HR) of cervical cancer in relation to screening status at age 61-65 from Cox models, adjusted for birth cohort and level of education, conditioning on women's screening history in their 50s. In women unscreened in their 50s, the cumulative incidence up to age 80 was 5.0 per 1,000 women, and screening at age 61-65 was associated with a lower risk for cervical cancer (HR = 0.42, 95% CI 0.24-0.72), corresponding to a decrease of 3.3 cancer cases per 1,000 women. A higher cumulative incidence and similarly statistically significant risk decrease was seen for women with abnormal smears in their 50s. In women adequately or inadequately screened with only normal results between age 51 and age 60, the cumulative incidence of cervical cancer from age 61 to 80 was 1.6 and 2.5 per 1,000 women, respectively, and further screening at age 61-65 was not associated with statistically significant decreases of cervical cancer risk up to age 80, but with fewer cancer cases of advanced stages at age 61-65. Adjustment for potential lifestyle confounders was limited. In this study, cervical screening with cytology at age 61-65 was associated with a statistically significant reduction of subsequent cervical cancer risk for women who were unscreened, or screened with abnormalities, in their 50s. In women screened with normal results in their 50s, the risk for future cancer was not sizeable, and the risk reduction associated with continued screening appeared limited. These findings should inform the current debate regarding age and criteria to discontinue cervical screening.

Deformities of the anterior cervical spine are an established cause of dysphagia. Whereas osteophytes and spinal fusion hardware have been reported to alter bolus flow and contribute to swallowing dysfunction, the relationship between abnormal spine curvature and swallowing dysfunction is not established. The purpose of this investigation was to evaluate the association between cervical kyphosis and objective measures of swallowing dysfunction on videofluoroscopy. Case-control study of patients presenting to tertiary dysphagia center. All videofluoroscopic swallow studies (VFSS) performed at our institution, between August 1, 2014, and August 1, 2015, were retrospectively reviewed to identify patients with abnormal cervical kyphosis, according to Cobb and Jackson angle measurements. Patients with kyphosis were age- and gender-matched to persons without kyphosis. VFSS and demographic parameters were collected and compared between groups. Thirty-six patients with cervical kyphosis exceeding two standard deviations (SD) beyond established age-specific normal ranges were identified. The mean age of the entire cohort was 61.6 (SD ±19.1) years. Mean pharyngeal area was 3.34 cm 2 greater in kyphosis patients compared to controls (95% confidence interval [CI]: 0.47-5.21 cm 2 ; P = .0007). This was associated with increased hypopharyngeal transit time (0.57 seconds, 95% CI: 0.045-1.09 seconds, P = .034), and higher prevalence of penetration (P = .014). There was no significant difference in the pharyngeal constriction ratio (PCR), a surrogate measure of pharyngeal strength (P = .83). Patients with cervical spine kyphosis have a significantly dilated pharynx (P = .0007), elongated hypopharyngeal transit time (P = .034), and worsened penetration aspiration scores (P = .021). Absence of a difference in PCR suggests adequate compensation as a group. 3b. Laryngoscope, 127:1832-1837, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

The cervical spine in Chiari I patient with syringomyelia has significantly different anteroposterior diameters than it does in Chiari I patients without syringomyelia. We tested the hypothesis that patients with idiopathic syringomyelia (IS) also have abnormal cervical spinal canal diameters. The finding in both groups may relate to the pathogenesis of syringomyelia. Local institutional review boards approved this retrospective study. Patients with IS were compared to age-matched controls with normal sagittal spine MR. All subjects had T1-weighted spin-echo (500/20) and T2-weighted fast spin-echo (2000/90) sagittal cervical spine images at 1.5 T. Readers blinded to demographic data and study hypothesis measured anteroposterior diameters at each cervical level. The spinal canal diameters were compared with a Mann-Whitney U test. The overall difference was assessed with a Friedman test. Seventeen subjects were read by two reviewers to assess inter-rater reliability. Fifty IS patients with 50 age-matched controls were studied. IS subjects had one or more syrinxes varying from 1 to 19 spinal segments. Spinal canal diameters narrowed from C1 to C3 and then enlarged from C5 to C7 in both groups. Diameters from C2 to C4 were narrower in the IS group (p < 0.005) than in controls. The ratio of the C3 to the C7 diameters was also smaller (p = 0.004) in IS than controls. Collectively, the spinal canal diameters in the IS were significantly different from controls (Friedman test p < 0.0001). Patients with IS have abnormally narrow upper and mid cervical spinal canal diameters and greater positive tapering between C3 and C7.

Cervical cancer remains a major health problem, especially in developing countries. Colposcopic examination is used to detect high-grade lesions in patients with a history of abnormal pap smears. New technologies are needed to improve the sensitivity and specificity of this technique. We propose to test the potential of fluorescence confocal microscopy to identify high-grade lesions. We examined the quantification of ex vivo confocal fluorescence microscopy to differentiate among normal cervical tissue, low-grade Cervical Intraepithelial Neoplasia (CIN), and high-grade CIN. We sought to (1) quantify nuclear morphology and tissue architecture features by analyzing images of cervical biopsies; and (2) determine the accuracy of high-grade CIN detection via confocal microscopy relative to the accuracy of detection by colposcopic impression. Forty-six biopsies obtained from colposcopically normal and abnormal cervical sites were evaluated. Confocal images were acquired at different depths from the epithelial surface and histological images were analyzed using in-house software. The features calculated from the confocal images compared well with those features obtained from the histological images and histopathological reviews of the specimens (obtained by a gynecologic pathologist). The correlations between two of these features (the nuclear-cytoplasmic ratio and the average of three nearest Delaunay-neighbors distance) and the grade of dysplasia were higher than that of colposcopic impression. The sensitivity of detecting high-grade dysplasia by analysing images collected at the surface of the epithelium, and at 15 and 30 μm below the epithelial surface were respectively 100, 100, and 92 %. Quantitative analysis of confocal fluorescence images showed its capacity for discriminating high-grade CIN lesions vs. low-grade CIN lesions and normal tissues, at different depth of imaging. This approach could be used to help clinicians identify high-grade CIN in clinical settings.

In order to clarify the characteristics of fatty acid metabolism in patients with myocardial infarction (MI), we performed myocardial imaging with 123I-beta-methyl-p-iodophenylpentadecanoic acid (BMIPP) and we compared these findings with exercise stress (Ex) and resting myocardial perfusion imaging with 99mTc-methoxyisobutylisonitrile (MIBI) and left ventricular wall motion index (WMI) which were obtained by left ventriculography. We studied 55 patients with MI, 14 patients with recent MI (RMI) and 41 patients with old MI (OMI), and myocardial images were divided into 17 segments and myocardial uptake of the radionuclide was graded from 0 (normal) to 3 (maximal abnormality). In 28 patients we compared segmental defect score (SDS) with WMI which were obtained by centerline method at the corresponded segments. As a whole, the mean total defect scores (TDSs) of BMIPP and Ex were similar and they were greater than the mean TDS of resting perfusion. In 30 patient (55%) TDS of BMIPP was greater than that of TDS of resting perfusion. In 24 patients perfusion abnormality developed by Ex and the location of BMIPP abnormality coincided with the abnormality of Ex. But in the other 6 patients Ex did not induce any abnormality and they were all RMI and infarcted coronary artery was patent. However in the group with TDS of BMIPP identical to TDS of resting perfusion (25 patients), 92% did not show myocardial perfusion abnormality after Ex. In the comparison of SDS and WMI, myocardial segments were divided into 3 groups; both SDSs of BMIPP and resting perfusion were normal or borderline abnormality (Group 1, 82 segments), SDS of resting perfusion was normal or borderline and SDS of BMIPP was definitely abnormal (Group 2, 10 segments) and both SDSs of BMIPP and resting perfusion were definitely abnormal (Group 3, 48 segments). In Group 1, WMS (-0.41 +/- 0.77) was significantly (p < 0.001) greater than those of Group 2 (-2.14 +/- 0.50) and Group 3 (-2.32 +/- 0.67). But there was no difference between Group 2 and 3. These findings suggested that in the segments with mismatch between BMIPP and resting perfusion reflects stunned myocardium. These results suggested that in half of the patients with MI, abnormal fatty acid metabolism may appear in viable myocardium such as jeopardized myocardium and myocardium which recently recovered from severe ischemia like acute MI and BMIPP imaging was useful to know the history of myocardial ischemia.

We report the development of an all-fiber-optic scanning endomicroscope capable of high-resolution second harmonic generation (SHG) imaging of biological tissues and demonstrate its utility for monitoring the remodeling of cervical collagen during gestation in mice. The endomicroscope has an overall 2.0 mm diameter and consists of a single customized double-clad fiber, a compact rapid two-dimensional beam scanner, and a miniature compound objective lens for excitation beam delivery, scanning, focusing, and efficient SHG signal collection. Endomicroscopic SHG images of murine cervical tissue sections at different stages of normal pregnancy reveal progressive, quantifiable changes in cervical collagen morphology with resolution similar to that of bench-top SHG microscopy. SHG endomicroscopic imaging of ex vivo murine and human cervical tissues through intact epithelium has also been performed. Our findings demonstrate the feasibility of SHG endomicroscopy technology for staging normal pregnancy, and suggest its potential application as a minimally invasive tool for clinical assessment of abnormal cervical remodeling associated with preterm birth.

Background Cervical dystonia, also known as spasmodic torticollis, is a chronic disorder in which patients exhibit involuntary repetitive contractions of neck muscles resulting in abnormal postures or movements. Occasionally, there is also a dystonic head tremor. The underlying mechanisms for cervical dystonia and dystonic tremor are not clear, and treatments are limited. Case Report In the present cases, two females with head tremor starting in adolescence developed worsening symptoms of cervical dystonia with dystonic tremor in their 60s. On osteopathic physical examination, both had a vertical type strain to the sphenobasilar synchondrosis. Discussion Vertical strains are more frequently found in patients after head trauma, congenital or later in life, than in healthy patients, and head trauma may have been a precipitating factor in these patients. There were improvements in cervical dystonia symptoms, including tremor, in both patients after osteopathic manual treatment. PMID:28119789

Serbia is one of the countries with highest incidence and mortality rates for cervical cancer in Central and South Eastern Europe. Introducing a risk index could provide a powerful means for targeting groups at high likelihood of having an abnormal cervical smear and increase efficiency of screening. The aim of the present study was to create and assess validity ofa index for prediction of an abnormal Pap test result. The study population was drawn from patients attending Departments for Women's Health in two primary health care centers in Serbia. Out of 525 respondents 350 were randomly selected and data obtained from them were used as the index creation dataset. Data obtained from the remaining 175 were used as an index validation data set. Age at first intercourse under 18, more than 4 sexual partners, history of STD and multiparity were attributed statistical weights 16, 15, 14 and 13, respectively. The distribution of index scores in index-creation data set showed that most respondents had a score 0 (54.9%). In the index-creation dataset mean index score was 10.3 (SD-13.8), and in the validation dataset the mean was 9.1 (SD=13.2). The advantage of such scoring system is that it is simple, consisting of only four elements, so it could be applied to identify women with high risk for cervical cancer that would be referred for further examination.

The participation of NOTCH signaling in invasive cervical cancer (ICC) remains controversial since both tumor suppressive and oncogenic properties have been described. Additionally, the role of NUMB, a negative regulator of NOTCH, remains unclear in ICC. We aimed to investigate the role of NOTCH1 and NUMB expression and their localization in cervical intraepithelial neoplasia (CIN) and ICC samples. A total of 144 biopsies were obtained from the Instituto Nacional de Cancerología, México from 2004 to 2017, and were subjected to immunohistochemistry for NOTCH1 and NUMB. We found that nuclear NOTCH1 expression was more frequently found in CIN samples compared with ICC (77.55% vs. 15.79%, p = 0.001). NUMB was almost exclusively found in the nucleus of CIN samples (32.65% vs. 6.32%, p = 0.001). Cytoplasmic expression of NOTCH1 (44.21%) and NUMB (35.79%) was the most frequent localization in ICC. Multivariable-adjusted analysis showed that the loss of nuclear NOTCH1 expression was an independent predictor of malignancy (β = –3.428, 95% confidence interval [95% CI] = –5.127, –1.728, p = 0.001). In contrast, the association between cytoplasmic NUMB expression and cervical cancer was lost after adjusting for nuclear NOTCH1 expression (β = 2.074, 95% [CI] = –0.358, 4.506, P = 0.094). Additionally, patients with cytoplasmic NOTCH1 expression showed a borderline association with longer overall survival (OS) than those with nuclear NOTCH1 expression (P = 0.08). Our data suggest that the loss of nuclear NOTCH1 but not NUMB might be an independent predictor of malignancy in cervical cancer. PMID:29721172

High risk types of human papillomaviruses E6/E7 oncogenes and their association with tumor suppressor genes products are the key factors of cervical carcinogenesis. This study proposed them as specific markers for cervical dysplasia screening. The aim of the study is to compare the clinical and prognostic significance of HPV E6/E7 mRNA as an early biomarker versus HPV DNA detection and cytology in triage of woman for cervical cancer. The study group consists of 413 women: 258 NILM, 26 ASC-US, 81 LSIL, 41 HSIL, and 7 unsatisfactory cytology. HPV4AACE screening, real-time multiplex PCR and MY09/11 consensus PCR primers methods were used for the HPV DNA detection. The real-time multiplex nucleic acid sequence-based assay (NucliSENS EasyQ HPV assay) was used for HPV E6/E7 mRNA detection of the five most common high risk HPV types in cervical cancer (16, 18, 31, 33, and 45). The results show that HPV E6/E7 mRNA testing had a higher specificity 50% (95% CI 32-67) and positive predictive value (PPV) 62% (95% CI 46-76) for CIN2+ compared to HPV DNA testing that had specificity of 18% (95% CI 7-37) and PPV 52% (95% CI 39-76) respectively. The higher specificity and PPV of HPV E6/E7 mRNA testing are valuable in predicting insignificant HPV DNA infection among cases with borderline cytological finding. It can help in avoiding aggressive procedures (biopsies and over-referral of transient HPV infections) as well as lowering patient's anxiety and follow up period. © 2015 Wiley Periodicals, Inc.

Data on the impact of abnormal cervical smear results on health-related quality of life (HrQoL) are scarce. We aimed to (i) prospectively assess the HrQoL of women who were informed of an abnormal smear result; (ii) identify predictors of greater negative psychosocial impact of an abnormal result; and (iii) prospectively estimate the quality-adjusted life-years (QALYs) lost following an abnormal result. Between 08/2006 and 08/2008, 492 women with an abnormal result and 460 women with a normal result, frequency matched for age and clinic, were recruited across Canada. HrQoL was measured at recruitment and 4 and 12 weeks later with the EuroQol, Short Form-12, short Spielberg State-Trait Anxiety Inventory (STAI) and HPV Impact Profile. Three blocks of potential predictors of higher psychosocial impact were tested by hierarchical modeling: (i) socio-demographics; (ii) sexual activity; and (iii) smear result severity, communication, and understanding. Receiving an abnormal result significantly increased anxiety (STAI mean difference between both groups = 8.3). Initial anxiety decreased over time for the majority of women. However, 35% of women had clinically meaningful anxiety at 12 weeks (i.e. STAI scores ≥0.5 standard deviation of the controls). These women reported a lower socio-economic level, did not completely understand the information about their result and perceived themselves at higher risk of cancer. QALY lost following an abnormal result were between 0.007 and 0.009. Receiving an abnormal smear has a statistically significant and clinically meaningful negative impact on mental health. However, this negative impact subsides after 12 weeks for the majority of women. Copyright © 2011 John Wiley & Sons, Ltd.

Cervical cancer is a prevalent disease in many developing countries. Colposcopy is the most common approach for screening cervical intraepithelial neoplasia (CIN). However, its clinical efficacy heavily relies on the examiner's experience. Spectroscopy is a potentially effective method for noninvasive diagnosis of cervical neoplasia. In this paper, we introduce a hyperspectral imaging technique for noninvasive detection and quantitative analysis of cervical neoplasia. A hyperspectral camera is used to collect the reflectance images of the entire cervix under xenon lamp illumination, followed by standard colposcopy examination and cervical tissue biopsy at both normal and abnormal sites in different quadrants. The collected reflectance data are calibrated and the hyperspectral signals are extracted. Further spectral analysis and image processing works are carried out to classify tissue into different types based on the spectral characteristics at different stages of cervical intraepithelial neoplasia. The hyperspectral camera is also coupled with a lab microscope to acquire the hyperspectral transmittance images of the pathological slides. The in vivo and the in vitro imaging results are compared with clinical findings to assess the accuracy and efficacy of the method.

Background Appropriate and timely screening can significantly reduce breast and cervical cancer morbidity and mortality. Racial/ethnic minorities and immigrant populations have lower screening rates and delays in follow-up after abnormal tests. Purpose In this study, we examined the relationship between age, comorbidity, breast and cervical cancer literacy in a sample of African American, Latina, and Arab women (N=371) from Detroit, Michigan. Methods Age-adjusted Charlson Comorbidity Index (ACC) was used characterize the impact of age and comorbidity has on breast and cervical cancer literacy; Breast Cancer Literacy Assessment Tool was used to assess breast cancer literacy; Cervical Cancer Literacy Assessment Tool was used to assess cervical cancer literacy. ANOVA was used to assess the relationship between ACC, breast and cervical cancer screening and group differences. Results There was a statistically significant difference between breast cancer literacy (Breast-CLAT total scores) scores (F(2,367)= 17.31, p= < 0.01). ACC had a greater impact on breast cancer literacy for African American F(2,214) =11, p = <0.01. PMID:26333609

An institutional review board-approved cross-sectional investigation of a professional ballet company was undertaken. Male and female adult dancers were eligible for inclusion. Four plain radiographs were obtained (standing anteroposterior pelvis, bilateral false profile, and supine Dunn 45°) and verified for adequacy. Cam and pincer deformities, dysplasia, borderline dysplasia, and osteoarthritis were defined. All plain radiographic parameters were measured and analyzed on available radiographs. Student t test, chi-square test (and Fisher exact test), and Spearman correlation analyses were performed to compare sexes, groups, and the effect of select radiographic criteria. A total of 47 dancers were analyzed (21 males, 26 females; mean age (±SD), 23.8 ± 5.4 years). Cam deformity was identified in 25.5% (24/94) of hips and 31.9% (15/47) of subjects, with a significantly greater prevalence in male dancers than females (48% hips and 57% subjects vs 8% hips and 12% subjects; P < .001 and P = .001, respectively). Seventy-four percent of subjects had at least 2 of 6 radiographic signs of pincer deformity. Male dancers had a significantly greater prevalence of both prominent ischial spine and posterior wall signs (P = .001 and P < .001, respectively), while female dancers had a significantly greater prevalence of coxa profunda (85% female hips vs 26% male hips; P < .001). Eighty-nine percent of subjects had dysplasia or borderline dysplasia in at least 1 hip (37% dysplastic), with a significantly greater prevalence of dysplasia or borderline dysplasia in female versus male dancers (92% female hips vs 74% male hips; P < .022). Further, in those with dysplasia or borderline dysplasia, 92% of female and 82% of male dancers had bilateral findings. In this professional ballet company, a high prevalence of radiographic abnormalities was found, including cam and pincer deformity and dysplasia. The results also revealed several sex-related differences of these abnormalities in this unique population. The long-term implications of these findings in this group of elite athletes remain unknown, and this issue warrants future investigation. © 2015 The Author(s).

The consensus guidelines recognize adolescents as a special group and allow for more conservative follow- up of abnormal cytology and histology. The guidelines recognize the role of high rates of HPV infection and reinfection in teens, along with high rates of clearance of HPV and low rates of invasive cervical cancer. Risks of treatment are balanced with risk for disease progression. The cervical cancer vaccine is now recommended for teens. The approved vaccine protects against HPV related disease caused by four subtypes of HPV 6, 11, 16, and 18. The Food and Drug Administration has approved the vaccine as routine for 11- and 12-year-old girls. The vaccine is most effective prior to HPV exposure or before the sexual debut. In South Carolina only 4.8% of high school girls indicate having sexual intercourse before age 13. Vaccination provides an opportunity to review risky behaviors with adolescent patients and to encourage healthy, safe lifestyles. Vaccination is not protective for sexually transmitted infections and this can be emphasized at vaccination visits as well. The importance of cancer screening can also be reviewed with patients at vaccination visits.

Prophylactic human papillomavirus (HPV) vaccination programs constitute major public health initiatives worldwide. We assessed the global effect of quadrivalent HPV (4vHPV) vaccination on HPV infection and disease. PubMed and Embase were systematically searched for peer-reviewed articles from January 2007 through February 2016 to identify observational studies reporting the impact or effectiveness of 4vHPV vaccination on infection, anogenital warts, and cervical cancer or precancerous lesions. Over the last decade, the impact of HPV vaccination in real-world settings has become increasingly evident, especially among girls vaccinated before HPV exposure in countries with high vaccine uptake. Maximal reductions of approximately 90% for HPV 6/11/16/18 infection, approximately 90% for genital warts, approximately 45% for low-grade cytological cervical abnormalities, and approximately 85% for high-grade histologically proven cervical abnormalities have been reported. The full public health potential of HPV vaccination is not yet realized. HPV-related disease remains a significant source of morbidity and mortality in developing and developed nations, underscoring the need for HPV vaccination programs with high population coverage.

Cervical cancer and infection with human immunodeficiency virus (HIV) are both important public health problems in South Africa (SA). The aim of this study was to determine the prevalence of cervical squamous intraepithelial lesions (SILs), high-risk human papillomavirus (HR-HPV), HPV viral load and HPV genotypes in HIV positive women initiating anti-retroviral (ARV) therapy. A cross-sectional survey was conducted at an anti-retroviral (ARV) treatment clinic in Cape Town, SA in 2007. Cervical specimens were taken for cytological analysis and HPV testing. The Digene Hybrid Capture 2 (HC2) test was used to detect HR-HPV. Relative light units (RLU) were used as a measure of HPV viral load. HPV types were determined using the Roche Linear Array HPV Genotyping test. Crude associations with abnormal cytology were tested and multiple logistic regression was used to determine independent risk factors for abnormal cytology. The median age of the 109 participants was 31 years, the median CD4 count was 125/mm3, 66.3% had an abnormal Pap smear, the HR-HPV prevalence was 78.9% (Digene), the median HPV viral load was 181.1 RLU (HC2 positive samples only) and 78.4% had multiple genotypes. Among women with abnormal smears the most prevalent HR-HPV types were HPV types 16, 58 and 51, all with a prevalence of 28.5%. On univariate analysis HR-HPV, multiple HPV types and HPV viral load were significantly associated with the presence of low and high-grade SILs (LSIL/HSIL). The multivariate logistic regression showed that HPV viral load was associated with an increased odds of LSIL/HSIL, odds ratio of 10.7 (95% CI 2.0 - 57.7) for those that were HC2 positive and had a viral load of 181.1 RLU. Women initiating ARVs have a high prevalence of abnormal Pap smears and HR-HPV. Our results underscore the need for locally relevant, rigorous screening protocols for the increasing numbers of women accessing ARV therapy so that the benefits of ARVs are not partially offset by an excess risk in cervical cancer.

Spinal cord injury without radiographic abnormalities (SCIWORA) is thought to represent mostly a pediatric entity and its incidence in adults is rather underreported. Some authors have also proposed the term spinal cord injury without radiologic evidence of trauma, as more precisely describing the condition of adult SCIWORA in the setting of cervical spondylosis. The purpose of the present study was to evaluate adult patients with cervical spine injuries and radiological-clinical examination discrepancy, and to discuss their characteristics and current management. During a 16-year period, 166 patients with a cervical spine injury were admitted in our institution (Level I trauma center). Upper cervical spine injuries (occiput to C2, 54 patients) were treated mainly by a Halo vest, whereas lower cervical spine injuries (C3-T1, 112 patients) were treated surgically either with an anterior, or posterior procedure, or both. Seven of these 166 patients (4.2%) had a radiologic-clinical mismatch, i.e., they presented with frank spinal cord injury with no signs of trauma, and were included in the study. Magnetic resonance imaging was available for 6 of 7 patients, showing intramedullary signal changes in 5 of 6 patients with varying degrees of compression from the disc and/or the ligamentum flavum, whereas the remaining patient had only traumatic herniation of the intervertebral disc and ligamentum flavum bulging. Follow-up period was 6.4 years on average (1-10 years). This retrospective chart review provides information on adult patients with cervical spinal cord injuries whose radiographs and computed tomography studies were normal. It furthers reinforces the pathologic background of SCIWORA in an adult population, when evaluated by magnetic resonance imaging. Particularly for patients with cervical spondylosis, special attention should be paid with regard to vascular compromise by predisposing factors such as smoking or vascular disease, since they probably contribute in the development of SCIWORA.

The Sprengel's deformity is a congenital anomaly of the shoulder girdle with an elevation of the scapula and limitation of movement of the shoulder. Sprengel's deformity is frequently associated with cervical spine malformations such as: spinal synostosis, spina bifida and an abnormal omovertebral fibrous, cartilaginous or osseus connection. The diagnosis of Sprengel's deformity is based on a clinical examination and radiological procedures. In every case of Sprengel's deformity plain radiography and computed tomography should be performed. Three-dimensional (3D) reconstructions allow to visualize precise topography and spatial proportions of examined bone structures. 3D reconstruction also enables an optional rotation of visualized bone structures in order to clarify the anatomical abnormalities and to plan surgical treatment.

Cumulative Impact of HIV and Multiple Concurrent Human Papillomavirus Infections on the Risk of Cervical Dysplasia

Infection with HIV is known to increase the risk of cervical cancer. In addition, evidence suggests that concurrent infection with multiple human papillomavirus (HPV) genotypes increases the risk of cervical dysplasia more than infection with a single HPV genotype. However, the impact of the combination of HIV coinfection and presence of multiple concurrent HPV infections on the risk of cervical dysplasia is uncertain. We compared the results of HPV testing and Pap smears between HIV-infected and HIV-uninfected young women to assess the cumulative impact of these two conditions. We found that both HIV and the presence of multiple concurrent HPV infections are associated with increased risk of associated Pap smear abnormality and that the impact of these two risk factors may be additive.

One of the leading biosocial theories of borderline personality disorder (BPD) suggests that individuals with BPD have biologically based abnormalities in emotion regulation contributing to more intense and rapid responses to emotional stimuli, in particular, invalidation [Linehan, M.M., 1993. Cognitive-Behavioral Treatment of Borderline Personality Disorder. Guilford, New York.]. This study used a 2 by 2 experimental design to test whether young women with features of BPD actually show increased physiological arousal in response to invalidation. Twenty-three women ages 18 to 29 who endorsed high levels of BPD symptoms and 18 healthy controls were randomly assigned to hear either a validating or invalidating comment during a frustrating task. Although we found preliminary support for differential response to these stimuli in self-report of valence, we found neither self-report nor physiological evidence of hyperarousal in the BPD features group, either at baseline or in response to invalidation. Interestingly, the BPD features group reported significantly lower comfort with emotion, and comfort was significantly associated with affective valence but not arousal. We discuss implications for understanding and responding to the affective intensity of this population.

Smith-Magenis syndrome (SMS) is a multiple congenital anomaly, mental retardation (MCA/MR) syndrome associated with deletion of chromosome 17 band p11.2. As part of a multi-disciplinary clinical, cytogenetic, and molecular approach to SMS, detailed clinical studies including radiographic neurologic, developmental, ophthalmologic, otolaryngologic, and audiologic evaluations were performed on 27 SMS patients. Significant findings include otolaryngologic abnormalities in 94%, eye abnormalities in 85%, sleep abnormalities (especially reduced REM sleep) in 75%, hearing impairment in 68% (approximately 65% conductive and 35% sensorineural), scoliosis in 65% brain abnormalities (predominantly ventriculomegaly) in 52%, cardiac abnormalities in at least 37%, renal anomalies (especially duplication of themore » collecting system) in 35%, low thyroxine levels in 29%, low immunoglobulin levels in 23%, and forearm abnormalities in 16%. The measured IQ ranged between 20-78, most patients falling in the moderate range of mental retardation at 40-54, although several patients scored in the mild or borderline range. The frequency of these many abnormalities in SMS suggests that patients should be evaluated thoroughly for associated complications both at the time of diagnosis and at least annually thereafter. 42 refs., 2 figs., 3 tabs.« less

Human immunodeficiency virus (HIV)-positive women have a high prevalence of human papillomavirus (HPV), and are infected with a broader range of HPV types than HIV-negative women. We aimed to determine the prevalence of cervical cytologic abnormalities, high-risk (HR)-HPV prevalence, type distribution according to the severity of cervical lesions and CD4 cell count and identify factors associated with HR-HPV infection among women living with HIV in Manaus, Amazonas. We enrolled 325 women living with HIV that attended an infectious diseases referral hospital. Each woman underwent a gynecological exam, cervical cytology, HR-HPV detection by Polymerase chain Reaction (PCR) using the BD Onclarity™ HPV Assay, colposcopy and biopsy, when necessary. We assessed the associations between potential risk factors and HR-HPV infection. Overall, 299 (92.0%) women had a PCR result. The prevalence of HR-HPV- infection was 31.1%. The most prevalent HR-HPV types were: 56/59/66 (32.2%), 35/39/68 (28.0%), 52 (21.5%), 16 (19.4%), and 45 (12.9%). Among the women with HR-HPV infection (n = 93), 43.0% had multiple infections. Women with HPV infection showed higher prevalence of cervical abnormalities than that HPV-negative (LSIL: 22.6% vs. 1.5%; HSIL: 10.8% vs. 0.0%). The prevalence of HR-HPV among women with cytological abnormalities was 87.5% for LSIL and 100.0% for HSIL. Women with CD4 < 200 cell/mm 3 showed the highest HR-HPV prevalence (59.3%) although this trend was not statistically significant (p-value = 0.62). The mean CD4 cell count decreased with increasing severity of cervical lesions (p-value = 0.001). The multivariable analysis showed that increasing age was associated with a decreased risk of HR-HPV infection with an adjusted prevalence odds ratio of 0.9 (95.0% CI: 0.9-1.0, p-value: 0.03) for each additional year. The only factor statistically significant associated with HR-HPV infection was CD4 cell count. HR-HPV and abnormal cytology prevalence are high among women in the Amazonas. The low CD4 cell count was an important determinant of HPV infection and abnormal cytological findings. HPV quadrivalent vaccination used in Brazil might not offer protection for an important fraction of HPV-related disease burden in women living with HIV. This is partly explained by the high presence of non targeted vaccine HR-HPVs, such as the HPV genotype groups 56/59/66, 35/39/68 and individually HPV-52 and HPV-45, some of which contribute to high-grade lesion.

Objective To assess head posture using cervical spine X-rays to find out whether forward head posture is related to myofascial pain syndrome (MPS) in neck and shoulder. Methods Eighty-eight participants who were diagnosed with MPS in neck and shoulder were evaluated in this study. Four parameters (distance among head, cervical spines, and shoulder, and cervical angle) were measured from lateral view of cervical spine X-ray. The location and number of trigger points in the neck and shoulder and symptom duration were evaluated for each patient. Results Both horizontal distances between C1 vertebral body and C7 spinous process and between the earhole and C7 vertebral body were negatively correlated with cervical angle reflecting cervical lordosis (p<0.05). Younger patients had significantly (p<0.05) less cervical angle with more forward head posture. There was no relationship between MPS (presence, location, and number of trigger points) and radiologic assessments (distance parameters and the cervical angle). Conclusion Forward head posture and reduced cervical lordosis were seen more in younger patients with spontaneous neck pain. However, these abnormalities did not correlate with the location or the number of MPS. Further studies are needed to delineate the mechanism of neck pain in patients with forward head posture.

Several new techniques have been developed to improve the sensitivity of cervical carcinoma screening and reduce equivocal cytologic diagnoses referred to as atypical squamous cells of undetermined significance (ASCUS). This study evaluates the effectiveness of combining two newly introduced diagnostic techniques: preparation of thin-layer cytologic slides from ThinPrep liquid buffer and selected Hybrid Capture testing for human papillomavirus (HPV) DNA. Because HPV DNA detection has been strongly associated with the presence of a cervical carcinoma precursor ("squamous intraepithelial lesion," or SIL), HPV testing might be useful for identifying women with ASCUS who have an underlying SIL. Two hundred specimens demonstrating diverse cervical abnormalities were selected from a prospective population-based study of 9174 women conducted in Costa Rica. The entire cohort had been screened with conventional cervical smears; ThinPrep slides made from liquid buffer, PAPNET, a computerized slide reading system; and Cervicography. Patients with any abnormal screening test were referred for colposcopy, punch biopsy, and loop excision of cases with high grade cytologic abnormalities not explained by punch biopsy. For this investigation, the results of ThinPrep cytology and HPV testing alone and in combination were compared with the final diagnoses, with an emphasis on the detection of carcinoma and high grade SIL. The 200 subjects studied included 7 women with a final diagnosis of carcinoma, 44 with high grade SIL, 34 with low grade SIL, 51 with a variety of equivocal diagnoses, and 64 with normal diagnoses. A ThinPrep cytologic diagnosis of SIL or carcinoma was made in 39 (76%) of the 51 women with final diagnoses of high grade SIL or carcinoma. Hybrid Capture testing detected carcinoma-associated types of HPV DNA in 100% of women with carcinoma, 75% with high grade SIL, 62% with low grade SIL, 20% with equivocal final diagnoses, and 12% of normal women. If colposcopy referral had been limited to women with a ThinPrep diagnosis of SIL or a diagnosis of ASCUS associated with the detection of carcinoma-associated HPV DNA from the same vial, 100% of women with carcinoma and 80% with high grade SIL would have been examined. To achieve this high sensitivity in the entire population of 9174 women would have required the referral of about 7% of the population. The combined screening strategy would have performed marginally better than optimized conventional screening with referral of any abnormal cytology (ASCUS and above). A cervical carcinoma screening technique which uses a single sample for cytopathology and HPV testing to triage equivocal diagnoses may be promising if it proves to be cost-effective.

The aim is to evaluate 1) the visibility of cervical squamocolumnar junction (SCJ) after cryotherapy treatment and 2) to evaluate the effectiveness of cryotherapy treatment originally performed as part of a safety, acceptability, and feasibility (SAFE) demonstration project evaluating the SAFE of visual inspection with acetic acid (VIA) followed by immediate offer of cryotherapy among those who were tested positive and eligible for treatment. A total of 704 women presented at 1-year follow-up exam during which VIA was performed again by nurses. Six hundred and forty eight (92.0%) women received colposcopy and any kind of biopsy, if indicated, by trained physician colposcopists at a referral hospital. At 1 year, VIA nurses assessed 42 of 648 referred women (6.5%) as abnormal (test positive or suspected cancer). The SCJ was visible to the colposcopists in 91.7% (594/648) of the women. Among 42 women assessed as abnormal by the nurses, colposcopic findings were abnormal in 83.3% (35/42), with one low-grade squamous intraepithelial lesion, two high-grade squamous intraepithelial lesion (HSIL), and one adenocarcinoma confirmed later by biopsy. Among 606 VIA negative women, colposcopy was abnormal in only 23.4% (142/606), with two cases of HSIL confirmed later. Given that the SCJ was visible in the vast majority of women (91.7%) after cryotherapy, VIA could be used to provide follow-up for women previously treated. The disease negative rate after cryotherapy (no human papillomavirus infection, no cervical intraepithelial neoplasia, and no cancer) at 1 year after treatment was 85.5% (554/648).

Recent policy revisions allow greater inclusion of military women in operational and/or deployable positions (ie, shipboard, overseas, and war zone duty assignments), but these positions can create unique health care challenges. Military members are often transient due to deployments and change of duty stations, impacting timely follow-up care for treatable health conditions. There has been minimal research on challenges or strategies in preventive health screening and follow-up for US military women. The purpose of this qualitative research study was to describe US Navy women's experiences with abnormal cervical cancer screenings requiring colposcopic follow-up care. Ship- and shored-based women receiving care at a military colposcopy clinic completed interviews about their experience. Two forms of narrative analysis, Labov's sociolinguistic structural analysis and Braun and Clarke's thematic analysis, were employed to gain a more robust understanding of the women's experiences. The sample was comprised of 26 women (16 ship-based, 10 shore-based). Five themes were identified: 1) It's like this bombshell (initial abnormal results notification); 2) I didn't understand (self-discovery process); 3) Freaked (emotional toll); 4) It's kind of like this back and forth (scheduling and navigating care); and 5) It really opened my eyes (lessons learned). The women's stories highlighted some issues unique to military health care, such as operational demands and follow-up care; other issues are likely common for most women learning about an abnormal cervical cancer screening result. Areas important for practice and future research include improving notification practices, providing information, understanding women's fear, and continuity of care. Research exploring educational initiatives and self-management practices are critical within military populations. © 2016 by the American College of Nurse-Midwives.

To determine if natural human papillomavirus (HPV) infection would induce an anamnestic response to quadrivalent (qHPV) vaccine in women with Systemic Lupus Erythematosus (SLE). Thirty four women (19-50 years) with mild to moderate and minimally active or inactive SLE received standard qHPV vaccine. Neutralizing antibody titers to HPV 6, 11, 16 and18 were evaluated pre- and post- vaccine using HPV competitive Luminex Immunoassay. For each HPV type, logistic regressions were performed to explore the relationship between a positive titer at baseline with their final geometric mean titer and with the rise in titer. Fisher's Exact Test was used to assess the association of at least one positive HPV antibody test at baseline and history of abnormal pap. History of abnormal pap smear/cervical neoplasia occurred in 52.9%. Baseline anti HPV antibody titers: 21% = negative for all 4 HPV types, 79% = positive for ≥1 of the HPV types. Statistical analysis showed: those with a history of abnormal pap smear/cervical neoplasia were likely to have a positive anti-HPV antibody result pre-vaccine to ≥ 1 of the 4 types, p = 0.035 Fisher's Exact Test. In general, HPV exposed women showed higher post vaccine GMTs than HPV unexposed women with higher point estimates. However, when examining the rise in titers using logistic regression, there was no evidence of an anamnestic response. Prior HPV infection and cervical neoplasia in SLE are linked with no anamnestic response to HPV vaccine. This supports not checking HPV-antibodies pre-vaccine. Women with SLE should be vaccinated for HPV.

Currently, a comprehensive program for screening and early detection of cervical cancer does not exist in Iran. This study aimed to determine the prevalence of abnormal Papanicolaou (Pap) smears and some related factors among women living in Zanjan, Iran. This cross-sectional study was conducted in 2012 in Zanjan on 4274 married women aged 20-65 years. The study participants were selected through two-stage cluster sampling. After obtaining written consent, demographic and fertility questionnaires were completed. Samples from cervix were obtained through a standard method using the Rover Cervex- Brush. Evaluation and interpretation of the samples were reported using the Bethesda 2001 method. Data were statistically analyzed using chi-square and logistic regression models. Most inflammatory changes in the samples were mild (37.4%). Abnormal atypical changes in the epithelial cells were found in 4.04%. The highest percentage of abnormal changes in the epithelial cells was atypical squamous cells of undetermined significance (ASCUS) (1.9%). Abnormal results of Pap smear was significantly and independently associated with age, papillomavirus infection, and lack of awareness about Pap smear tests. Given the high prevalence of inflammatory and precancerous changes in this study, compared to other studies in Iran and other Muslim countries, and the effect of demographic variables and individual factors on abnormal results, increasing the awareness of women and their families regarding the risk factors for cervical cancer, preventive measures such as screening, and timely treatment seem necessary.

Anal cancer is one of the most common non-AIDS defining malignancies, especially in men who have sex with men and women living with HIV (WLHIV). To evaluate the prevalence and incidence of precursor lesions (high-grade squamous intraepithelial lesions [HSIL]) and anal cancer in our cohort of women and to compare them to cervical lesions; to calculate the percentage of patients that acquire and clear oncogenic genotypes (HR-HPV) in the anal canal; and to determine predictive factors for anal HPV infection. Prospective-longitudinal study (May 2012-December 2016). At baseline (V1) and follow up visits, anal mucosa samples were taken in liquid medium for cytology and HPV PCR. In cases of abnormal anal cytology and/or positive HR-HPV PCR results, a high resolution anoscopy was performed. Patients were also referred to the gynaecologist. Ninety five women with an average age of 43.7years were included. At baseline, 11.6% had cervical abnormalities (4.1% CIN1, 2.2% CIN2/3, 1.1% cervical cancer), 64.3% anal abnormalities (50% LSIL/AIN1, 9.5% HSIL/AIN2/3 and 2.4% anal cancer) and 49.4% had HR-HPV genotypes. During 36months of follow up, the incidence of anal HSIL was 16×1,000 person-years; 14.8% acquired HR-HPV genotypes and 51.2% cleared them, P=.007. No patients presented CIN1/2/3/ or cervical cancer. In the multivariate analysis we found the following predictive factors for HR-HPV infection: smoking (RR: 1.55, 95%CI: 0.99-2.42), number of sexual partners >3 (RR: 1.69; 95%CI: 1.09-2.62), cervical and anal dysplasia (RR: 1.83; 95%CI: 1.26-2.67) and (RR: 1.55; 95%CI: 1.021-2.35), respectively. Despite clearance rates of anal oncogenic genotypes being higher than acquisition rates, prevalence and incidence of HSIL were still high and greater than cervical HSIL. Therefore, screening for these lesions should perhaps be offered to all WLHIV. Copyright © 2017 Elsevier España, S.L.U. and Sociedad Española de Enfermedades Infecciosas y Microbiología Clínica.

Patients with Laron syndrome have an inborn growth hormone resistance. We investigated abnormalities in the upper airways and cervical spine in patients with Laron syndrome. We prospectively examined 11 patients (one child aged 9 years and 10 adults aged 36-68 years), 10 of whom underwent MR imaging of the spine or head; nine, radiography of the cervical spine; and four, CT of C1-C2. The width of the spinal canal was evaluated visually and quantitatively and compared with reference values. The smallest diameter of the oropharynx and the thickness of the palate were measured and compared with reference values. Nine age-matched female patients referred for MR imaging for unrelated reasons served as control subjects. Cervical spinal stenosis was present in seven of the adult patients, within a confidence interval of 95%. Anomaly of the dens compatible with os odontoideum was present in three patients, causing focal myelomalacia in two. The atlanto-odontoid joint showed osteoarthritic changes in six of the adult patients. The mediolateral diameter of the oropharynx was significantly smaller in the patients with Laron syndrome than in the control subjects (P <.005). There was no difference in the thickness of the soft palate. Patients with Laron syndrome develop significant narrowing of the cervical spinal canal and early degenerative changes of the atlanto-odontoid joint. Laron syndrome is associated with os odontoideum causing myelomalacia. The dimensions of the oropharynx are small. Patients may be prone to neurologic morbidity and sleep disturbances. Routine MR imaging of the cervical spine is recommended in these patients.

Cervical cancer is the most common cancer among women in developing nations. Nearly 90% of the cases have been linked to the presence of high-risk human papillomavirus (hrHPV) types 16 and 18. The risk of cervical cancer may be high in female sex workers (FSWs) due to multiple sexual partners. This study aimed to determine the prevalence of cytological abnormalities and hrHPV types 16 and 18 in FSWs in Chandigarh, North India using the liquid-based cytology (LBC) approach. The cervical brush samples were collected from 120 FSW and 98 age-matched healthy controls (HCs). These were subjected to pap smear using conventional method, LBC and the detection of hrHPV types 16 and 18 was carried out using polymerase chain reaction. The LBC samples showed better cytological details and also reduced the number of unsatisfactory smears from 11% in Pap to 1.5% in the LBC. A significantly higher number of inflammatory smears were reported in FSWs (51.7% vs. 34.7%, P = 0.01). The hrHPV types 16/18 were detected in 33/120 (27.5%) FSW versus 23/98 (23.5%) HCs. The risk of acquiring hrHPV was higher in FSWs, who had age at first sex ≤25 years, higher income and the habit of smoking. The high prevalence of hrHPV among FSWs and HCs suggests the need for the implementation of effective National Screening Programme for early detection of hrHPV types to decrease the burden of cervical cancer, especially in high-risk population.

Introduction Homeless persons have minimal opportunities to complete recommended cancer screening. The rates and predictors of cervical cancer screening are understudied among homeless women in the US. Methods We enrolled 297 homeless women 21-65 years old residing in 6 major New York City shelters from 2012 to 2014. We used a validated national survey to determine the proportion and predictors of cervical cancer screening using cytology (Pap test). Results Mean age was 44.72 (±11.96) years. Majority was Black, heterosexual, single, with high school or lower education; 50.9 % were smokers and 41.7 % were homeless more than a year. Despite a 76.5 % proportion of self-reported Pap test within the past 3 years, 65 % of women assumed their Pap test results were normal or did not get proper follow up after abnormal results. Forty-five-point-nine percent of women did not know about frequency of Pap test or causes of cervical cancer. Lower proportion of up-to-date Pap test was associated with lack of knowledge of recommended Pap test frequency (p < 0.01) and relationship between HPV and an abnormal Pap test (p < 0.01). Conclusions Self-reported Pap testing in homeless women was similar to a national sample. However, the majority of women surveyed were not aware of their results, received limited if any follow up and had significant education gaps about cervical cancer screening. We recommend improved counseling and patient education, patient navigators to close screening loops, and consideration of alternative test-and-treat modalities to improve effective screening.

Clearance of cervical spine injury (CSI) in the obtunded or comatose blunt trauma patient remains controversial. In patients with unreliable physical examination and no evidence of CSI on computed tomography (CT), magnetic resonance imaging of the cervical spine (CS-MRI) is the typical follow-up study. There is a growing body of evidence suggesting that CS-MRI is unnecessary with negative findings on a multi-detector CT (MDCT) scan. This review article systematically analyzes current literature to address the controversies surrounding clearance of CSI in obtunded blunt trauma patients. A literature search through MEDLINE database was conducted using all databases on the National Center for Biotechnology Information (NCBI) website (www.ncbi.nlm.nih.gov) for keywords: "cervical spine injury," "obtunded," and "MRI." The search was limited to studies published within the last 10 years and with populations of patients older than 18 years old. Eleven studies were included in the analysis yielding data on 1535 patients. CS-MRI detected abnormalities in 256 patients (16.6%). The abnormalities reported on CS-MRI resulted in prolonged rigid c-collar immobilization in 74 patients (4.9%). Eleven patients (0.7%) had unstable injury detected on CS-MRI alone that required surgical intervention. In the obtunded blunt trauma patient with unreliable clinical examination and a normal CT scan, there is still a role for CS-MRI in detecting clinically significant injuries when MRI resources are available. However, when a reliable clinical exam reveals intact gross motor function, CS-MRI may be unnecessary.

To evaluate the recurrence rate of high-grade squamous intraepithelial lesions in postmenopausal women previously submitted to laser CO2 conization and the role of persistent oncogenic HPV types. Fifty-five patients with a cytological diagnosis of high-grade squamous intraepithelial lesions were triaged with a standard colposcopy. Hormonal replacement therapy was considered as significative in influencing cervical trophism. Vaginal smears for microbiological examination were obtained. H-R HPV test was performed by PCR. The follow-up checks including cytology, colposcopy and HVP test were performed for a minimum of 5 years. Histological analysis revealed 19 CIN2 (cervical intraepithelial lesions) and 36 CIN3 lesions. The cumulative failure rate at first treatment was 14%. HPV test was positive for HPV 16 type in all patients. Forty-two patients during the follow up checks resulted negative to cytology, colposcopy and HR HPV test. At the one-year follow-up check, 7 patients revealed normal cytological and abnormal colposcopical findings and persistent positive HR HPV test. At the five-year follow-up check, 14 patients with a normal cytological smear had a recurrence of CIN2/3 and positive HR HPV test. In postmenopause, the correct management of H-R squamous intraepithelial lesions is still debated. However, a satisfactory follow-up is the main requirement for the conservative management. HPV typing in the follow-up is important to detect persistent types to identify women at risk of developing cervical abnormalities. The incidence of cervical neoplasia does not decrease with increasing age. Since HPV positivity predicted subsequent infection, testing postmenopausal patients for the virus may be a cost-effective method of disease prevention.

Atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion in abnormal cervical cytology among young women in cervical cancer screening is an increasing health burden, and comparative effectiveness studies of different management options for such diagnoses are needed. The objective of the study was to compare the incidence of invasive cervical cancer, following different management options pursued after an atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion index smear. In this nationwide cohort study, we included all women aged 22-50 years and resident in Sweden 1989-2011 and with at least 1 cervical smear registered during the study period (n = 2,466,671). Follow-up of a first atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion cytological diagnosis within 25 months was classified as repeat cytology, colposcopy/biopsy, or without further assessment. Incidence rate ratios and 95% confidence intervals of subsequent cervical cancer within 6.5 years following atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion were estimated using Poisson regression by age group and management strategy. Women managed with repeat cytology within 6 months after atypical squamous cells of undetermined significance or low-grade squamous intraepithelial lesion cytology had a similar risk of cervical cancer compared with colposcopy/biopsy (incidence rate ratio, 1.1, 95% confidence interval, 0.5-2.5, and incidence rate ratio, 2.0, 95% confidence interval, 0.6-6.5, respectively) among women aged 22-27 years. For women aged 28 years and older, women managed with repeat cytology had a higher risk for cervical cancer than women managed with colposcopy/biopsy. Our findings suggest that women with a first cytological diagnosis of atypical squamous cells of undetermined significance/low-grade squamous intraepithelial lesion up to age 27 years may indeed be safely followed up with repeat cytology within 6 months. A large amount of colposcopies that are currently performed in this group, therefore, could safely be discontinued. Copyright © 2016 The Authors. Published by Elsevier Inc. All rights reserved.

The Papanicolaou (Pap) screen has been successful in reducing cervical cancer; but exhibits low sensitivity when detecting cervical dysplasia. Use of molecular biomarkers in Pap tests may improve diagnostic accuracy. Monoclonal antibodies to Minichromosome Maintenance Protein 2 (MCM2) and DNA Topoisomerase II α (TOP2A) were selected for use in IHC based on their ability to differentiate normal from diseased cervical tissues in tissue microarrays. Enhanced Green Fluorescent Protein Western blot analysis was used to help identify binding epitopes specific to MCM2 and TOP2A antibody clones. Antibody affinity was determined by solution phase affinity measurement and immunohistochemistry was performed using high affinity MCM2 or TOP2A antibodies on serial histological sections. Antibody clones to MCM2 and TOP2A clones were selected based on their ability to detect over expression in abnormal cervical epithelia. In IHC, MCM2-27C5.6 and MCM2-26H6.19 demonstrated superior staining in abnormal cervical tissue over the MCM2-CRCT2.1 antibody. A combination of MCM2 and TOP2A antibodies showed greater staining when compared to staining with any of the antibodies alone on serial histological sections. Distinct linear epitopes were elucidated for each of the MCM2 and TOP2A clones. Affinity values (Kd) for MCM2 or TOP2A antibodies had a similar range. In a research study, the MCM2 and TOP2A (BD ProEx™ C) antibody cocktail showed increased epithelia staining with increasing dysplasia. The use of BD ProEx™ C in combination with H&E staining enhanced immunohistochemical discrimination of dysplastic and non-dysplastic FFPE cervical tissue specimens. BD ProEx™ C containing MCM2 and TOP2A antibodies showed strong specific nuclear staining that correlated with increased dysplasia and lesion severity. Enhanced performance of the antibodies was linked to their unique topography recognition. BD ProEx™ C incorporates antibodies that enhance detection of CIN2+ cervical disease.

Triage of the abnormal Papanicolaou smear in pregnancy requires colposcopic evaluation and directed biopsy. If histologic cervical intraepithelial neoplasia is confirmed, the patient can be managed with observations and can be re-evaluated in the postpartum period. If evidence of microinvasion is present, conization must be performed. For patients with invasive disease, a delay in therapy until fetal maturity is achieved does not compromise survival.

2011-01-01

Strong evidence now supports the adoption of cervical cancer prevention strategies that explicitly focus on persistent infection with the causal agent, human papillomavirus (HPV). To inform an evidence-based transition to a new public health approach for cervical cancer screening, we summarize the natural history and cervical carcinogenicity of HPV and discuss the promise and uncertainties of currently available screening methods. New HPV infections acquired at any age are virtually always benign, but persistent infections with one of approximately 12 carcinogenic HPV types explain virtually all cases of cervical cancer. In the absence of an overtly persistent HPV infection, the risk of cervical cancer is extremely low. Thus, HPV test results predict the risk of cervical cancer and its precursors (cervical intraepithelial neoplasia grade 3) better and longer than cytological or colposcopic abnormalities, which are signs of HPV infection. The logical and inevitable move to HPV-based cervical cancer prevention strategies will require longer screening intervals that will disrupt current gynecologic and cytology laboratory practices built on frequent screening. A major challenge will be implementing programs that do not overtreat HPV-positive women who do not have obvious long-term persistence of HPV or treatable lesions at the time of initial evaluation. The greatest potential for reduction in cervical cancer rates from HPV screening is in low-resource regions that can implement infrequent rounds of low-cost HPV testing and treatment. PMID:21282563

Diagnostic performance of dual-staining cytology for cervical cancer screening: A systematic literature review.

PubMed

Tjalma, Wiebren A A

2017-03-01

Cervical cancer screening saves lives. Secondary prevention in cervical cancer screening relies on the results of primary cytology and/or HPV testing. However, primary screening with cytology has a low sensitivity, and HPV screening has a low specificity. This means that either cancers are missed, or women are over-treated. To improve performance outcomes, the concept of dual-stain cytology (CINtec ® PLUS Cytology test) has been introduced. In this approach, additional staining with p16/Ki-67 is performed in cases where cytology results are abnormal (LSIL or ASCUS) and/or HPV-positive. Another way to describe this approach might be "diagnostic" cytology. In order to assess the value of this "diagnostic cytology", a systematic literature review was conducted of dual-stain cytology performance across multiple studies until May 2016. In a Belgian screening population (women age 25-65 years), dual-stain cytology was significantly more sensitive (66%) and slightly less specific (-1.0%) than cytology. In the population referred to colposcopy or with abnormal cytology (ASCUS, LSIL), dual-staining showed a significantly higher increase in specificity, and a slightly lower sensitivity than HPV testing. Specificity gains resulted in fewer false positives and an increase in the number of correct referrals to colposcopy. Dual-staining with p16/Ki-67 cytology is an attractive biomarker approach for triage in cervical cancer screening. Copyright © 2017 Elsevier B.V. All rights reserved.

Reducing false negatives in clinical practice: the role of neural network technology.

PubMed

Mango, L J

1996-10-01

The fact that some cervical smears result in false-negative findings is an unavoidable and unpredictable consequence of the conventional (manual microscopic) method of screening. Errors in the detection and interpretation of abnormality are cited as leading causes of false-negative cytology findings; these are random errors that are not known to correlate with any patient risk factor, which makes the false-negative findings a "silent" threat that is difficult to prevent. Described by many as a labor-intensive procedure, the microscopic evaluation of a cervical smear involves a detailed search among hundreds of thousands of cells on each smear for a possible few that may indicate abnormality. Investigations into causes of false-negative findings preceding the discovery of high-grade lesions found that many smears had very few diagnostic cells that were often very small in size. These small cells were initially overlooked or misinterpreted and repeatedly missed on rescreening. PAPNET testing is designed to supplement conventional screening by detecting abnormal cells that initially may have been missed by microscopic examination. This interactive system uses neural networks, a type of artificial intelligence well suited for pattern recognition, to automate the arduous search for abnormality. The instrument focuses the review of suspicious cells by a trained cytologist. Clinical studies indicate that PAPNET testing is sensitive to abnormality typically missed by conventional screening and that its use as a supplemental test improves the accuracy of screening.

Towards improving cervical cancer screening in Nigeria: a review of the basics of cervical neoplasm and cytology.

Dim, C C

Cervical cancer screening is the key to reducing the incidence and mortality of cervical cancer in developing countries. In the absence of a national screening program, healthcare givers in Nigeria are encouraged to routinely inform and screen eligible women. This review aims at equipping health workers for this task by re-educating them on the basics of the disease and its screening by cytology. Relevant texts and online databases including Pubmed, African Journal Online, and Google Scholar, were searched for relevant literature on the subject area. Persistent infection by a high-risk human papilloma virus, especially types 16 and 18, is necessary for the development of cervical cancer. The exfoliation of cells from the metaplastic squamous cells of transformation zone of the cervix is the basis of cervical cytology. Organized Pap screening reduces the incidence and mortality of cervical cancer, but screening protocols vary. Nevertheless, annual screening is not recommended except for high-risk women such as HIV-positive women. Abnormal Pap smear results are currently reported using either the Bethesda System or the British Society for Clinical Cytology classification, and colposcopy with or without biopsy are necessary when indicated. In conclusion, the use of cervical cytology to detect pre-cancerous lesions followed by an appropriate treatment when necessary is the key to reducing invasive cervical cancer. The task of provider-initiated counseling and testing for cervical cancer by health practitioners requires update on the current etio-pathology of cervical cancer, and its screening as reviewed.

To assess the feasibility and efficacy of Keyes punch biopsy instrument (KP) in diagnosing cervical lesions and compare it with cervical punch biopsy forceps (CP). 75 women having satisfactory colposcopy with abnormal transformation zone were included and paired colposcopic directed biopsies were taken using KP followed by CP from the same target area. It was feasible in all cases to take cervical biopsy with KP after increasing its effective length. The volume of gross specimen obtained by KP was less than CP (0.076 ± 0.097 vs. 0.101 ± 0.156 cm3, p = 0.061), however on microscopic examination, mean length and mean depth of tissue in KP was greater than CP by 0.06 mm (p = 0.810) and 0.14 mm (p = 0.634) respectively. Exact agreement was found with the final surgical specimen in 42% of cases in both the biopsy forceps. KP is almost at par with CP for diagnosing preinvasive cervical lesions and is a useful adjunct to the existing armamentarium of biopsy forceps. © 2016 S. Karger AG, Basel.

Cervical cancer is a leading cause of death for women in low resource settings. In order to better detect cervical dysplasia, a low cost multi-spectral colposcope was developed utilizing low costs LEDs and an area scan camera. The device is capable of both traditional colposcopic imaging and multi-spectral image capture. Following initial bench testing, the device was deployed to a gynecology clinic where it was used to image patients in a colposcopy setting. Both traditional colposcopic images and spectral data from patients were uploaded to a cloud server for remote analysis. Multi-spectral imaging ( 30 second capture) took place before any clinical procedure; the standard of care was followed thereafter. If acetic acid was used in the standard of care, a post-acetowhitening colposcopic image was also captured. In analyzing the data, normal and abnormal regions were identified in the colposcopic images by an expert clinician. Spectral data were fit to a theoretical model based on diffusion theory, yielding information on scattering and absorption parameters. Data were grouped according to clinician labeling of the tissue, as well as any additional clinical test results available (Pap, HPV, biopsy). Altogether, N=20 patients were imaged in this study, with 9 of them abnormal. In comparing normal and abnormal regions of interest from patients, substantial differences were measured in blood content, while differences in oxygen saturation parameters were more subtle. These results suggest that optical measurements made using low cost spectral imaging systems can distinguish between normal and pathological tissues.

Motocross racing is a popular sport; however, its impact on the growing/developing pediatric spine is unknown. Using a retrospective cohort model, the authors compared the degree of advanced degenerative findings in young motocross racers with findings in age-matched controls. Patients who had been treated for motocross-related injury at the authors' institution between 2000 and 2007 and had been under 18 years of age at the time of injury and had undergone plain radiographic or CT examination of any spinal region were eligible for inclusion. Imaging was reviewed in a blinded fashion by 3 physicians for degenerative findings, including endplate abnormalities, loss of vertebral body height, wedging, and malalignment. Acute pathological segments were excluded. Spine radiographs from age-matched controls were similarly reviewed and the findings were compared. The motocross cohort consisted of 29 riders (mean age 14.7 years; 82% male); the control cohort consisted of 45 adolescents (mean age 14.3 years; 71% male). In the cervical spine, the motocross cohort had 55 abnormalities in 203 segments (average 1.90 abnormalities/patient) compared with 20 abnormalities in 213 segments in the controls (average 0.65/patient) (p = 0.006, Student t-test). In the thoracic spine, the motocross riders had 51 abnormalities in 292 segments (average 2.04 abnormalities/patient) compared with 25 abnormalities in 299 segments in the controls (average 1.00/patient) (p = 0.045). In the lumbar spine, the motocross cohort had 11 abnormalities in 123 segments (average 0.44 abnormalities/patient) compared with 15 abnormalities in 150 segments in the controls (average 0.50/patient) (p = 0.197). Increased degenerative changes in the cervical and thoracic spine were identified in adolescent motocross racers compared with age-matched controls. The long-term consequences of these changes are unknown; however, athletes and parents should be counseled accordingly about participation in motocross activities.

A narrow cervical spinal canal (CSC) is a well-known risk factor for cervical myelopathy (CM). However, no epidemiologic data of the CSC based on a population-based cohort are available. The purpose of the study was to investigate the age-related differences in CSC diameters on plain radiographs and to examine the associated magnetic resonance imaging (MRI) abnormalities including cervical cord compression and increased signal intensity (ISI) as well as the clinical CM with the narrow CSC. This was a cross-sectional study. Data were obtained from the baseline survey of the Wakayama Spine Study that was performed from 2008 to 2010 in a western part of Japan. Finally, a total of 959 subjects (319 men and 640 women; mean age, 66.4 years) were included. The outcome measures included in the study were the CSC diameter at C5 level on plain radiographs, cervical cord compression and ISI on sagittal T2-weighted MRI, and physical signs related to CM (eg, the Hoffmann reflex, hyperreflexia of the patellar tendon, the Babinski reflex, sensory and motor function, and bowel/bladder symptoms). The age-related differences of CSC diameters in men and women were investigated by descriptive statistics. The prevalence of MRI abnormalities and clinical CM was compared among the groups divided by the CSC diameter (less than 13, 13-15, and 15 mm or more). In addition, a logistic regression analysis was performed to determine the association of the CSC diameter with cervical cord compression/clinical CM after overall adjustment for age, sex, and body mass index. The CSC diameter was narrower with increasing age in both men and women. The prevalence of cervical cord compression, ISI, and the clinical CM was significantly higher in the narrower CSC group. The prevalence of cervical cord compression, ISI, and CM among subjects with CSC diameter less than 13 mm was 38.0%, 5.4%, and 10.1%, respectively. In the logistic model, the CSC diameter was a significant predictive factor for the clinical CM (p<.0001). This study firstly confirmed the age-related differences in CSC diameters and the significant association of the narrow CSC diameter with CM in a population-based cohort.

Pain assessment in self-injurious patients with borderline personality disorder using signal detection theory.

PubMed

Kemperman, I; Russ, M J; Clark, W C; Kakuma, T; Zanine, E; Harrison, K

1997-05-30

Signal detection theory measures of thermal responsivity were examined to determine whether differences in reported pain experienced during self-injurious behavior in female patients with borderline personality disorder (BPD) are explained by neurosensory factors and/or attitudinal factors (response bias). Female patients with BPD who do not experience pain during self-injury (BPD-NP group) were found to discriminate more poorly between noxious thermal stimuli of similar intensity, low P(A), than female patients with BPD who experience pain during self-injury (BPD-P group), female patients with BPD who do not have a history of self-injury (BPD-C group), and age-matched normal women. The BPD-NP group also had a higher response criterion, B (more stoical) than the BPD-C group. These findings suggest that 'analgesia' during self-injury in patients with BPD is related to both neurosensory and attitudinal/psychological abnormalities.

Treatment of personality disorder.

PubMed

Bateman, Anthony W; Gunderson, John; Mulder, Roger

2015-02-21

The evidence base for the effective treatment of personality disorders is insufficient. Most of the existing evidence on personality disorder is for the treatment of borderline personality disorder, but even this is limited by the small sample sizes and short follow-up in clinical trials, the wide range of core outcome measures used by studies, and poor control of coexisting psychopathology. Psychological or psychosocial intervention is recommended as the primary treatment for borderline personality disorder and pharmacotherapy is only advised as an adjunctive treatment. The amount of research about the underlying, abnormal, psychological or biological processes leading to the manifestation of a disordered personality is increasing, which could lead to more effective interventions. The synergistic or antagonistic interaction of psychotherapies and drugs for treating personality disorder should be studied in conjunction with their mechanisms of change throughout the development of each.

Spontaneous or idiopathic intramedullary bleeding is a very rare event in pediatric patients. This diagnosis requires an extended clinical, laboratory, and radiologic work-up to rule out all potential causes of hematomyelia. However, children may present with hematomyelia or spinal cord injury without radiographic abnormality even after a minor trauma. A 15-month-old girl presented with a 24-hour history of progressive neurologic deficits. A trivial trauma had occurred a few days before the clinical onset. Head computed tomography scan and craniospinal magnetic resonance imaging revealed an isolated hemorrhagic central medullary lesion extending from the obex to C3 level. No underlying causes of intramedullary bleeding were identified. In the absence of obvious vascular abnormalities, the patient underwent an urgent occipitocervical decompression with hematoma evacuation. Postoperatively, the patient's motor symptoms rapidly resolved, and she was discharged with cervical collar immobilization. We discuss the differential diagnosis of intramedullary bleeding in children, focusing on the diagnostic protocol and therapeutic options in this age group. Copyright © 2016 Elsevier Inc.

The underlying inflammation of endometrium may impede normal implantation of placenta during pregnancy. Our objective is to show cervical colonization of ureaplasma and/or mycoplasma as a marker of endometritis in pregnancies complicated with placenta previa that can be a risk factor for placenta accreta and peripartum hemorrhage. Cervical cultures for ureaplasma urealyticum and mycoplasma genitalium have been taken from the endocervical region of the cervix of the patients. Subsequent uterine lower segment bleeding suggesting placenta implantation defects have been evaluated during cesarean section. Of 25 patients: ten (40%) had negative cervical cultures for cervical mycoplasma and/or ureaplasma, 9 (36%) were found to be culture positive for cervical ureaplasma, 1 (4%) was found to be culture positive for cervical mycoplasma. Half of the 10 patients with positive cervical cultures for ureaplasma or mycoplasma and 6 of (40%) 15 patients with negative results had experienced lower uterine segment bleeding during cesarean section. Bacterial colonization of cervix in particular with ureaplasma and/or mycoplasma is found to be strongly associated with placenta previa. Before a planned pregnancy, treatment of this infection with appropriate antibiotics is necessary to prevent underlying uterine endometritis that increases the risk for abnormal implantation of placenta.

Carcinogenic human papillomaviruses (HPV) cause the majority of cervical cancers and other anogentical cancers. Large randomized trials have shown that HPV testing can be efficiently used for primary cervical cancer screening. Other applications include the triage of abnormal cytology results and the follow-up of women after treatment. Many assays have been developed to measure DNA, RNA, and proteins of HPV. The various tests can have very different applications. It is important to validate HPV assays before they are implemented in screening or clinical care. PMID:21845360

Update on current care guideline: Cytological changes in the cervix, vagina and vulva.

PubMed

Annually approximately 160 new cervical cancers are diagnosed in Finland. Screening has decreased both incidence and mortality by 80%. Both primary HPV-testing and Pap smear can be used in screening. In the future HPV vaccination will decrease the number of cervical cancers. Abnormal findings in Pap smears indicate management. LSIL lesions are followed up especially among young women and HSIL lesions treated. Follow-up after treatment should be reliably arranged, because increased risk of cancer remains ever after treatment.

The objective of this study was to estimate the sensitivity of plain radiographs in identifying bony or ligamentous cervical spine injury in children. We identified a retrospective cohort of children younger than 16 years with blunt trauma-related bony or ligamentous cervical spine injury evaluated between 2000 and 2004 at 1 of 17 hospitals participating in the Pediatric Emergency Care Applied Research Network. We excluded children who had a single or undocumented number of radiographic views or one of the following injuries types: isolated spinal cord injury, spinal cord injury without radiographic abnormalities, or atlantoaxial rotary subluxation. Using consensus methods, study investigators reviewed the radiology reports and assigned a classification (definite, possible, or no cervical spine injury) as well as film adequacy. A pediatric neurosurgeon, blinded to the classification of the radiology reports, reviewed complete case histories and assigned final cervical spine injury type. We identified 206 children who met inclusion criteria, of which 127 had definite and 41 had possible cervical spine injury identified by plain radiograph. Of the 186 children with adequate cervical spine radiographs, 168 had definite or possible cervical spine injury identified by plain radiograph for a sensitivity of 90% (95% confidence interval, 85%-94%). Cervical spine radiographs did not identify the following cervical spine injuries: fracture (15 children) and ligamentous injury alone (3 children). Nine children with normal cervical spine radiographs presented with 1 or more of the following: endotracheal intubation (4 children), altered mental status (5 children), or focal neurologic findings (5 children). Plain radiographs had a high sensitivity for cervical spine injury in our pediatric cohort.

To determine the utility of cervical spine MRI in blunt trauma evaluation for instability after a negative non-contrast cervical spine CT. A review of medical records identified all adult patients with blunt trauma who underwent CT cervical spine followed by MRI within 48 h over a 33-month period. Utility of subsequent MRI was assessed in terms of findings and impact on outcome. A total of 1,271 patients with blunt cervical spine trauma underwent both cervical spine CT and MRI within 48 h; 1,080 patients were included in the study analysis. Sixty-six percent of patients with a CT cervical spine study had a negative study. Of these, the subsequent cervical spine MRI had positive findings in 20.9%; 92.6% had stable ligamentous or osseous injuries, 6.0% had unstable injuries and 1.3% had potentially unstable injuries. For unstable injury, the NPV for CT was 98.5%. In all 712 patients undergoing both CT and MRI, only 1.5% had unstable injuries, and only 0.42% had significant change in management. MRI for blunt trauma evaluation remains not infrequent at our institution. MRI may have utility only in certain patients with persistent abnormal neurological examination. • MRI has limited utility after negative cervical CT in blunt trauma. • MRI is frequently positive for non-specific soft-tissue injury. • Unstable injury missed on CT is infrequent.

A 79-year-old man presented with primary intramedullary malignant lymphoma with a presyrinx state in the cervical cord manifesting as left hemiparesis and hemidysesthesia. The magnetic resonance imaging (MRI) scan showed an intramedullary mass in the cervical spinal cord at the level of C1 and T2-weighted image prolongation from the medulla to the level of C5. According to the progression of hemiparesis, he underwent an emergency removal of the tumor under general anesthesia. The tumor was totally removed, and the peritumoral signal abnormality was not present in the postoperative MRI. Histological examination revealed diffuse large B cell lymphoma. While brain MRI, bone marrow puncture, and 18F-fluorodeoxy-glucose positron emission tomography (18FDG-PET) of the whole body were performed to find out a primary lesion, there were no abnormalities. He underwent a high-dose methotrexate-based chemotherapy and a local irradiation therapy (40Gy). He has been alive for more than two years since the symptom onset, and without any evidence of recurrence. This case suggests that malignant lymphoma, as an infiltrating and rapidly progressive tumor, may be accompanied by syrinx. PMID:29507854

Little is known about age-dependent variation in outcomes of cervical cytology with modern technologies. This population-based study evaluated age-dependent changes after routine implementation of ThinPrep and SurePath technology in two independent laboratories, and controlled for time trends in a third laboratory using manually read conventional cytology continually. Data were collected from the Danish National Health Care Registers. For each laboratory, we compared proportions of abnormal cytology defined as atypical squamous cells of undetermined significance or worse (ASCUS+) by age and technology phase. The study included 489,960 cytological samples with no recent abnormality from women aged 23-59 years, routinely screened between 1998 and 2007. Implementation of SurePath liquid-based cytology (LBC) was followed by an increase in abnormal cytology in women aged 23-29 years from 4.6 to 6.1%, relative proportion (RP): 1.31 [95% confidence interval (CI): 1.08-1.61], and a decrease in women aged 45-59 years from 2.9 to 2.0%, RP: 0.71 (95% CI: 0.60-0.83). Implementation of ThinPrep LBC was followed by a decrease in abnormal cytology both in women aged 23-29 years from 7.7 to 6.8%, RP: 0.89 (95% CI: 0.78-1.02) and in women aged 45-59 years from 3.4 to 1.0%, RP: 0.30 (95% CI: 0.24-0.37). With implementation of imaging-assisted reading, regardless of the brand of technology, the proportion of abnormality increased by around 30% in all age groups (range from 19 to 41%). In the laboratory with unchanged technology no trends in abnormality proportions were observed. The impact of LBC implementation on cytological abnormality proportions varied considerably across age groups. © 2013 UICC.

This study examined a possible association of dietary exposure to polybrominated biphenyls (PBBs), a brominated flame retardant, and self-reported abnormal Pap test results and cervical dysplasia as a precursor to cervical cancer. Women in Michigan who ingested contaminated poultry, beef, and dairy products in the early 1970s were enrolled in a population-based cohort study in Michigan. Serum PBB and serum polychlorinated biphenyl (PCB) concentrations were measured. Reproductive history and health information, including Pap test results, were self-reported by participants. Of the women, 23% (223 of 956) reported an abnormal Pap test. In unadjusted analyses, self-reporting an abnormal Pap test was associated with younger age, current smoking (hazard ratio [HR] 1.61, 95% confidence interval [CI] 1.19-2.17), and longer duration of lifetime use of oral contraceptives (≥10 years; HR 1.92, 95% CI 1.21-3.06). When adjusting for PCB exposure, age at the interview, and smoking history, there was a slightly elevated risk of self-reporting an abnormal Pap test among the highly exposed women compared to women with nondetectable PBB concentrations (PBB≥13 μg/L, HR 1.23, 95% CI 0.74-2.06); however, the CI was imprecise. When breastfeeding duration after the initial PBB measurement was taken into account, there was a reduced risk of self-reporting an abnormal Pap test among the highly exposed women who breastfed for ≥12 months (HR 0.41, 95% CI 0.06-3.03; referent group: women with nondetectable PBB concentrations who did not breastfeed). It remains important to evaluate the potential reproductive health consequences of this class of chemicals as well as other potential predictors of abnormal Pap tests.

The purpose of this study was to evaluate the feasibility of 3D ultrashort TE (UTE) MRI in depicting the cartilaginous endplate (CEP) and its abnormalities and to investigate the association between CEP abnormalities and disk degeneration on T2-weighted spin-echo (SE) MR images in cervical disks in vivo. Eight healthy volunteers and 70 patients were examined using 3-T MRI with the 3D UTE cones trajectory technique (TR/TE, 16.1/0.032, 6.6). In the volunteer study, quantitative and qualitative assessments of CEP depiction were conducted for the 3D UTE and T2-weighted SE imaging. In the patient study, CEP abnormalities were analyzed. Intersequence agreement between the images obtained with the first-echo 3D UTE sequence and the images created by subtracting the second-echo from the first-echo 3D UTE sequence (subtracted 3D UTE) and the intraobserver and interobserver agreements for 3D UTE overall were also tested. The CEP abnormalities on the 3D UTE images correlated with the Miyazaki grading of the T2-weighted SE images. In the volunteer study, the CEP was well visualized on 3D UTE images but not on T2-weighted SE images (p < 0.001). In the patient study, for evaluation of CEP abnormalities, intersequence agreements were substantial to almost perfect, intraobserver agreements were substantial to almost perfect, and interobserver agreements were moderate to substantial (p < 0.001). All of the CEP abnormalities correlated with the Miyazaki grade with statistical significance (p < 0.001). Three-dimensional UTE MRI feasibly depicts the CEP and CEP abnormalities, which may be associated with the severity of disk degeneration on T2-weighted SE MRI.

Cervical cancer is an important woman's health problems worldwide, especially in low socio-economic countries. The aim of this study was to compare the Pap smear screening results between Akha hill tribe and urban women who live in Chiang Rai province, Thailand. Screening was conducted for 1,100 Akha women and 1,100 urban women who came to have the Pap smear at Chiangrai Prachanukroh Hospital and 1 private cytology laboratory from January to June 2008. The demographic characteristics and factors related to abnormal Pap smears of these women were gathered using closed model questionnaires. Abnormal Rap smears were defined according to the Bethesda 2001 system. The results showed that the prevalence of abnormal Pap smears was 12.2% in Akha women and 4.5% in urban women. The highest prevalence of Pap abnormalities was found in the 41-50 years age group in both populations (4.5% in Akha and 1.7% in urban women). In both populations, abnormal Pap smears were found in <21 years age groups. From the questionnaires, the possible risk factors related to the higher prevalence of abnormal Pap smears in Akha women were early age at marriage (≤17 years), high frequency pregnacies and high parity and no/low education level. In conclusion, cervical cancer control by education and early detection by Pap smear screening is necessary for hill tribe women. More Pap smear screening service units should be set to improve the coverage for the risk group women who got married in young age, especial in ethnic groups.

Construct failure is an uncommon but well-recognized complication following anterior cervical corpectomy and fusion (ACCF). In order to screen for these complications, many centers routinely image patients at outpatient visits following surgery. There remains, however, little data on the utility of such imaging. The electronic medical record of all patients undergoing anterior cervical corpectomy and fusion at Dartmouth-Hitchcock Medical Center between 2004 and 2009 were reviewed. All patients had routine cervical spine radiographs performed perioperatively. Follow-up visits up to two years postoperatively were analyzed.  Sixty-five patients (mean age 52.2) underwent surgery during the time period. Eighteen patients were female. Forty patients had surgery performed for spondylosis, 20 for trauma, three for tumor, and two for infection. Forty-three patients underwent one-level corpectomy, 20 underwent two-level corpectomy, and two underwent three-level corpectomy, using an allograft, autograft, or both. Sixty-two of the fusions were instrumented using a plate and 13 had posterior augmentation. Fifty-seven patients had follow-up with imaging at four to 12 weeks following surgery, 54 with plain radiographs, two with CT scans, and one with an MRI scan. Unexpected findings were noted in six cases. One of those patients, found to have asymptomatic recurrent kyphosis following a two-level corpectomy, had repeat surgery because of those findings. Only one further patient was found to have abnormal imaging up to two years, and this patient required no further intervention. Routine imaging after ACCF can demonstrate asymptomatic occurrences of clinically significant instrument failure. In 43 consecutive single-level ACCF however, routine imaging did not change management, even when an abnormality was discovered. This may suggest a limited role for routine imaging after ACCF in longer constructs involving multiple levels.

Whiplash injury (WI) is commonly evaluated in medico-legal practice. With the aim of knowing the determining factors of WI's medico-legal prognosis, a prospective and observational study was carried out. One hundred and twenty consecutive patients who were clinically observed and evaluated in the Medico-Legal Clinic of Barcelona were studied. Socio-demographic, clinical, radiographic and evolutive factors were analyzed. We included 120 patients with a mean age of 35.6 (14) years (range, 4-74), with a homogeneous male/female distribution. An earlier cervical pathology was detected in 10% of patients; none of them had previous psychiatric pathology. 95% corresponded to road-traffic accident cases and there were 5 aggression cases. Over 50% of cases involved a rear-end collision. All patients had neck pain, almost 25% had headache and 13% had paresthesia. According to the Whiplash Association Disorders clinical classification, distribution in grades (G) was: G I 51%, G II 32% and G III 17%. Patients reported recovery within a mean time of 71.6 (46) days (range, 4-244), with 51,2 (45) no working days (range, 0-180 days). The 52% of the patients rest with complains. According to the recovery time, the following medico-legal prognostic factors were identified: age (p < 0.001), being female (p = 0.001), clinical grade (p < 0.001) and abnormal cervical MRI exploration (p < 0.001). Patients with previous cervical pathology reported more complaints (p = 0.001). In our study, WI affected young people of both sex mainly during rear-end collision. Worst medico-legal prognostic factors were age, being females, severity of initial clinical symptoms, previous cervical pathology and abnormal cervical MRI/CT.

Fibrofatty degeneration of myocardium in ARVC is associated with wall motion abnormalities. The aim of this study was to examine whether Cardiovascular Magnetic Resonance (CMR) based strain analysis using feature tracking (FT) can serve as a quantifiable measure to confirm global and regional ventricular dysfunction in ARVC patients and support the early detection of ARVC. We enrolled 20 patients with ARVC, 30 with borderline ARVC and 22 subjects with a positive family history but no clinical signs of a manifest ARVC. 10 healthy volunteers (HV) served as controls. 15 ARVC patients received genotyping for Plakophilin-2 mutation (PKP-2), of which 7 were found to be positive. Cine MR datasets of all subjects were assessed for myocardial strain using FT (TomTec Diogenes Software). Global strain and strain rate in radial, circumferential and longitudinal mode were assessed for the right and left ventricle. In addition strain analysis at a segmental level was performed for the right ventricular free wall. RV global longitudinal strain rates in ARVC (-0.68 ± 0.36 sec⁻¹) and borderline ARVC (-0.85 ± 0.36 sec⁻¹) were significantly reduced in comparison with HV (-1.38 ± 0.52 sec⁻¹, p ≤ 0.05). Furthermore, in ARVC patients RV global circumferential strain and strain rates at the basal level were significantly reduced compared with HV (strain: -5.1 ± 2.7 vs. -9.2 ± 3.6%; strain rate: -0.31 ± 0.13 sec(-1) vs. -0.61 ± 0.21 sec⁻¹). Even for patients with ARVC or borderline ARVC and normal RV ejection fraction (n=30) global longitudinal strain rate proved to be significantly reduced compared with HV (-0.9 ± 0.3 vs. -1.4 ± 0.5 sec(-1); p < 0.005). In ARVC patients with PKP-2 mutation there was a clear trend towards a more pronounced impairment in RV global longitudinal strain rate. On ROC analysis RV global longitudinal strain rate and circumferential strain rate at the basal level proved to be the best discriminators between ARVC patients and HV (AUC: 0.9 and 0.92, respectively). CMR based strain analysis using FT is an objective and useful measure for quantification of wall motion abnormalities in ARVC. It allows differentiation between manifest or borderline ARVC and HV, even if ejection fraction is still normal.

Characteristic findings of cervical Papanicolaou tests from transgender patients on androgen therapy: Challenges in detecting dysplasia.

The characteristic features of Papanicolaou (Pap) tests collected from female-to-male (FTM) transgender patients on androgen therapy have not been well defined in the literature. FTM transgender patients require cervical cancer screening with the same recommended frequency as cis-gender females. Dysplasia remains challenging to differentiate from atrophy. Without pertinent history, the atrophic findings in younger transgender patients can be misinterpreted as high-grade dysplasia. A review of all cervical Pap tests of transgender patients receiving androgen therapy (2010-2017) was performed. Bethesda diagnosis, cytomorphological features, HPV testing and cervical biopsy results were reviewed. Eleven transgender patients receiving androgen therapy were identified with 23 cervical Pap tests, 11 HPV tests and five cervical biopsies performed. A review of the Pap tests demonstrated: 57% negative for intraepithelial lesion; 13% unsatisfactory; 13% atypical squamous cells of undetermined significance; 13% atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion; and 4% high-grade squamous intraepithelial lesion. The rates of abnormal tests were higher than our age-matched cis-gender atrophic cohort rates of unsatisfactory (0.5%), atypical squamous cells of undetermined significance (7%), atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (0%) and high-grade squamous intraepithelial lesion (0.5%). The cytological findings from liquid-based preparations included dispersed and clustered parabasal-type cells, scattered degenerated cells, smooth evenly dispersed chromatin, and occasional mild nuclear enlargement and irregularity. Dysplastic cells had larger nuclei, hyperchromatic clumped chromatin, and more irregular nuclear contours. The evaluation of dysplasia can be challenging on Pap tests from transgender patients on androgen therapy. The cohort evaluated had higher rates of unsatisfactory and abnormal Pap tests. Pathologists should be familiar with the distinctive cytomorphological changes in the Pap tests from patients on androgen therapy to evaluate them appropriately. © 2018 John Wiley & Sons Ltd.

Hybrid capture-II and LCR-E7 PCR assays for HPV typing in cervical cytologic samples.

2001-10-15

As part of an ongoing cohort study in the Hokuriku region of Japan, cervical cell samples from histologically confirmed normal (n = 114) or abnormal (n = 286) women were examined for the presence of HPV DNA using a second-generation hybrid capture assay (HCA-II) and LCR-E7 PCR. HCA-II detected low-risk (HPV-6, -11, -42, 43 and -44) and high-risk (HPV-16, -18, -31, -33, -35, -39, -45, -51, -52, -56, -58, -59 and -68) HPV types, while LCR-E7 PCR detected an additional 7 HPV types and some uncharacterized types. In screening of high-grade squamous intraepithelial lesions (HSILs) and invasive cervical cancer, the sensitivities of HCA-II and LCR-E7 PCR testing the high-risk HPV types were 83% and 81%, respectively, while the specificity of both assays was 93%. The sensitivity of LCR-E7 PCR increased to 87%, which was significantly higher than that in HCA-II, when testing both high-risk and other HPV types. Sixty-eight inconsistent results (17% of total tested) from HCA-II and LCR-E7 PCR were due to (i) low copy number of HPV genome (false-negative for HCA-II, 5.3% and for LCR-E7 PCR, 1.3%), (ii) infection with HPV types undetectable by HCA-II (4.8%), (iii) multiple HPV infections (5%) or (iv) unknown reasons (0.8%). LCR-E7 PCR revealed that infections with HPV-16, -18, -31, -33, -35, -51, -52, -56, -58 or -67 was a high risk for cancer since these types predominated in HSIL and invasive cervical cancer. Samples showing high relative light units (>20) with a high-risk probe in HCA-II also gave positive results in LCR-E7 PCR and were generally associated with abnormal cervical lesions. Thus, we propose that both HCA-II and LCR-E7 PCR are valuable screening tests for premalignant and malignant cervical lesions. Copyright 2001 Wiley-Liss, Inc.

Cytological surveillance or referral to colposcopy for biopsy and recall if necessary or referral to colposcopy with immediate treatment based on colposcopic appearance. Data on resource use collected from participants throughout the duration of the trial (36 months), enabling the estimation of both the direct (health care) and indirect (time and travel) costs of management. Quality of life assessed at recruitment and at 12, 18, 24, and 30 months, using the EQ-5D instrument. Economic outcomes expressed as costs per case of cervical intraepithelial neoplasia (grade II or worse) detected, by trial arm, as confirmed at exit, and cost utility ratios (cost per quality adjusted life year (QALY) gained) for the three pairwise comparisons of trial arms. The mean three year discounted costs of surveillance, immediate treatment, and biopsy and recall were pound150.20 (euro177, $249), pound240.30 (euro283, $415), and pound241.10 (euro284, $4000), respectively, viewed from the health service perspective. From the social perspective, mean discounted costs were pound204.40 (euro241, $339), pound339.90 (euro440, $563), and pound327.50 (euro386, $543), respectively. Estimated at the means, the incremental cost effectiveness ratios indicated that immediate treatment was dominated by the other two management methods, although it did offer the lowest cost per case of cervical intraepithelial neoplasia detected and treated. The pronounced skews in the distributions indicated that probabilistic uncertainty analysis would offer more meaningful estimates of cost effectiveness. The observed differences in the cost effectiveness ratios between trial arms were not significant. Judged within the time frame of the TOMBOLA evaluation, there is no compelling economic reason to favour any one follow-up method over either of the others. ISRCTN 34841617.

Occipital neuralgia is a well-recognized cause of posterior head and neck pain that may associate mild sensory changes in the cutaneous distribution of the occipital nerves, lacking a recognizable local structural aetiology in most cases. Atypical clinical features or an abnormal neurological examination are alerts for a potential underlying cause of pain, although cases of clinically typical occipital neuralgia as isolated manifestation of lesions of the cervical spinal cord, cervical roots, or occipital nerves have been increasingly reported. We describe two cases (one with typical and another one with atypical clinical features) of occipital neuralgia secondary to paravertebral pyomyositis and vertebral relapse of multiple myeloma in patients with relevant medical history that aroused the possibility of an underlying structural lesion. We discuss the need for cranio-cervical magnetic resonance imaging in all patients with occipital neuralgia, even when typical clinical features are present and neurological examination is completely normal.

Borderline intellectual functioning (BIF) is a condition characterized by an intelligence quotient (IQ) between 70 and 85. BIF children present with cognitive, motor, social, and adaptive limitations that result in learning disabilities and are more likely to develop psychiatric disorders later in life. The aim of this study was to investigate brain morphometry and its relation to IQ level in BIF children. Thirteen children with BIF and 14 age- and sex-matched typically developing (TD) children were enrolled. All children underwent a full IQ assessment (WISC-III scale) and a magnetic resonance (MR) examination including conventional sequences to assess brain structural abnormalities and high resolution 3D images for voxel-based morphometry analysis. To investigate to what extent the group influenced gray matter (GM) volumes, both univariate and multivariate generalized linear model analysis of variance were used, and the varimax factor analysis was used to explore variable correlations and clusters among subjects. Results showed that BIF children, compared to controls have increased regional GM volume in bilateral sensorimotor and right posterior temporal cortices and decreased GM volume in the right parahippocampal gyrus. GM volumes were highly correlated with IQ indices. The present work is a case study of a group of BIF children showing that BIF is associated with abnormal cortical development in brain areas that have a pivotal role in motor, learning, and behavioral processes. Our findings, although allowing for little generalization to the general population, contribute to the very limited knowledge in this field. Future longitudinal MR studies will be useful in verifying whether cortical features can be modified over time even in association with rehabilitative intervention. PMID:25360097

Background. Few studies have addressed the timing of cervical cytologic abnormalities and human papillomavirus (HPV) positivity during the course of an infection. It remains largely unknown how infections detected by HPV and cytology wax and wane relative to each other. The aim of this analysis was to assess the longitudinal relationship of abnormal cytology and HPV positivity in a 7-year prospective study of 2500 women in Guanacaste, Costa Rica. Methods. At each semiannual or annual visit, cervical specimens were screened using liquid-based cytology and tested for >40 HPV types with use of MY09/MY11 L1 degenerate primer polymerase chain reaction–based methods. On the basis of previous work, we separated prevalent and newly detected infections in younger and older women. Results. Among newly detected HPV- and/or cytology-positive events, HPV and cytology appeared together ∼60% of the time; when discordant, HPV tended to appear before cytology in younger and older women. Combining newly and prevalently detected events, HPV and cytology disappeared at the same time >70% of the time. When discordant, HPV tended to disappear after cytology in younger and older women. Conclusions. Detection of HPV DNA and associated cytological abnormalities tend to come and leave together; however, when discordant, detection of HPV DNA tends to precede and/or last longer than associated cytologic abnormalities.

Individuals in rural areas are often restricted by the amount of physicians' availability, thus limiting access to healthcare in those settings. While Pap smear screening has increased across the United States, the rural South still reports high rates of cervical cancer and mortality. One solution to improve patient outcomes related to cervical cancer in rural settings is telecolposcopy. Women with abnormal Pap results or an abnormal visual examination needing an evaluation by colposcopy were referred to a hospital-based telecolposcopy program. Descriptive data are provided that include patients' access to care based on travel time and transportation costs. Over a 15-month time period, 940 unique patients were seen using telecolposcopy. Telecolposcopy was done at eight spoke sites across Arkansas representing patients from 72 of the 75 counties. Data for risk factors that include smoking, first sexual experience, and number of sexual partners in past 12 months and in a lifetime are discussed. Pap results and impression are provided. In addition, avoided transportation costs and travel time have been calculated and included. Cervical cancer is important public health concern especially for women residing in rural areas. We were able to demonstrate that our telecolposcopy program has provided sustainability statewide since its inception and that patients are willing to participate. In addition to providing increased access to care, the program also reduced travel time and costs associated with a face-to-face visit. Telecolposcopy should be further explored and utilized in rural settings as a way to reduce patient costs and improve cervical cancer outcomes.

Advances in MR imaging for cervical spondylotic myelopathy.

To outline the pathogenesis of cervical spondylotic myelopathy (CSM), the correlative abnormalities observed on standard magnetic resonance imaging (MRI), the biological implications and current status of diffusion tensor imaging (DTI), and MR spectroscopy (MRS) as clinical tools, and future directions of MR technology in the management of CSM patients. A systematic review of the pathogenesis and current state-of-the-art in MR imaging technology for CSM was performed. CSM is caused by progressive, degenerative, vertebral column abnormalities that result in spinal cord damage related to both primary mechanical and secondary biological injuries. The T2 signal change on conventional MRI is most commonly associated with neurological deficits, but tends not to be a sensitive predictor of recovery of function. DTI and MRS show altered microstructure and biochemistry that reflect patient-specific pathogenesis. Advanced imaging techniques, including DTI and MRS, show higher sensitivity to microstructural and biochemical changes within the cord, and may aid in management of CSM patients.

We report three cases of ciguatera fish poisoning. One patient died secondary to respiratory failure. Two patients showed elevated muscle enzymes and one patients had an abnormal cervical spinal MRI. MRI findings have not been previously described. MRI findings explain the mechanism of the L'hermitte phenomenon (a common complaint) among these patients. Respiratory failure is rare in ciguatera fish poisoning. Our findings suggest this could be related to respiratory muscles involvement.

Many emotional and behavioral problems first emerge in primary school and are the forerunners of mental health problems occurring in adolescence. However, the extent that these problems may be associated with academic failure has been explored less. We aimed to quantify the association between emotional and behavioral problems with academic performance. A stratified random sample of 8- to 9-year-olds (N = 1239) were recruited from schools in Australia. Data linkage was performed with a national assessment of academic performance to assess reading and numeracy. Parent report assessed emotional and behavioral problems with students dichotomized into "borderline/abnormal" and "normal" categories. One in 5 grade 3 students fell in the "borderline/abnormal" category. Boys with total difficulties (β = -47.8, 95% CI: -62.8 to -32.8), conduct problems, and peer problems scored lower on reading. Numeracy scores were lower in boys with total difficulties (β = -37.7, 95% CI: -53.9 to -21.5) and emotional symptoms. Children with hyperactivity/inattention scored lower in numeracy. Girls with peer problems scored lower in numeracy. Boys with emotional and behavioral problems in mid-primary school were 12 months behind their peers. Children with emotional and behavioral problems are at high risk for academic failure, and this risk is evident in mid-primary school. © 2017, American School Health Association.

Current trauma guidelines dictate that the cervical spine should not be cleared in intoxicated patients, resulting in prolonged immobilization or additional imaging. Modern computed tomography (CT) technology may obviate this and allow for immediate clearance. To analyze cervical spine clearance practices and the utility of CT scans of the cervical spine in intoxicated patients with blunt trauma. We performed a prospective observational study of 1668 patients with blunt trauma aged 18 years and older who underwent cervical spine CT scans from March 2014 to March 2015 at an American College of Surgeons-verified Level I trauma center. Intoxication was determined by serum alcohol levels and urine drug screens. Physical examination and CT scan findings were evaluated for cervical spine injuries (CSI) and the incidence of missed injuries. Clinically relevant CSIs requiring cervical stabilization. The hypotheses formed prior to data collection were that cervical CT scans are sensitive and specific enough to diagnose CSIs that require stabilization and that normal CT scans are sufficient to clear CSIs in intoxicated patients. Of 1668 patients, 1103 (66.1%) were male, with a mean (SD) age of 49 (20) years and a mean (SD) Injury Severity Score of 10 (9). Vehicular (734 [44.0%]) and falls (579 [34.7%]) were the most common mechanisms for hospitalization. Intoxication was identified in 632 of 1429 of patients tested (44.2%; 425 [29.7%] by serum alcohol levels and 350 [24.5%] by urine drug screens). Half (316 [50.0%]) were admitted with cervical spine immobilization, and 38 (12%) of these were solely owing to the presence of intoxication. There were 65 abnormal CT scans (10.3%) in the intoxicated group. Among 567 normal CT scans, 4 (0.7%) had central cord syndrome found on initial physical examination, and 1 (0.2%) had a symptomatic unstable ligament injury that was misread as normal on CT scan but was abnormal on magnetic resonance imaging. The 316 patients kept in a cervical collar for intoxication had no missed CSIs but were kept immobilized for a mean (SD) of 12 (19) hours. Computed tomographic scans had an overall negative predictive value of 99.2% for patients with CSIs and a negative predictive value of 99.8% for ruling out CSIs that required immobilization or stabilization. In this study, alcohol or drug intoxication was common and resulted in significant delays to cervical spine clearance. Computed tomographic scans were highly reliable for identifying all clinically significant CSIs. Spine clearance based on a normal CT scan among intoxicated patients with no gross motor deficits appears to be safe and avoids prolonged and unnecessary immobilization.

To audit routine colposcopy performance using 8 standard requirements of the National Health Service Cervical Screening Programme (NHSCSP). Records of women who underwent colposcopy for abnormal cervical cytology between January and December 2008 at Chiang Mai University Hospital, Thailand, were reviewed. The standard requirements were not achieved in 2 practices: (1) the proportion of women who had recordings of visibility of the transformation zone (96.6%) did not achieve the NHSCSP requirement of 100%; and (2) the rate of excisional biopsy (87.8%) was lower than the 95% minimum required. Colposcopic performance at Chiang Mai University Hospital was generally favorable. However, re-audit is necessary to ensure that unmet standards of performance are improved and achieved standards are maintained.

The Pittsburgh Cervical Cancer Screening Model: a risk assessment tool.

2010-05-01

Evaluation of cervical cancer screening has grown increasingly complex with the introduction of human papillomavirus (HPV) vaccination and newer screening technologies approved by the US Food and Drug Administration. To create a unique Pittsburgh Cervical Cancer Screening Model (PCCSM) that quantifies risk for histopathologic cervical precancer (cervical intraepithelial neoplasia [CIN] 2, CIN3, and adenocarcinoma in situ) and cervical cancer in an environment predominantly using newer screening technologies. The PCCSM is a dynamic Bayesian network consisting of 19 variables available in the laboratory information system, including patient history data (most recent HPV vaccination data), Papanicolaou test results, high-risk HPV results, procedure data, and histopathologic results. The model's graphic structure was based on the published literature. Results from 375 441 patient records from 2005 through 2008 were used to build and train the model. Additional data from 45 930 patients were used to test the model. The PCCSM compares risk quantitatively over time for histopathologically verifiable CIN2, CIN3, adenocarcinoma in situ, and cervical cancer in screened patients for each current cytology result category and for each HPV result. For each current cytology result, HPV test results affect risk; however, the degree of cytologic abnormality remains the largest positive predictor of risk. Prior history also alters the CIN2, CIN3, adenocarcinoma in situ, and cervical cancer risk for patients with common current cytology and HPV test results. The PCCSM can also generate negative risk projections, estimating the likelihood of the absence of histopathologic CIN2, CIN3, adenocarcinoma in situ, and cervical cancer in screened patients. The PCCSM is a dynamic Bayesian network that computes quantitative cervical disease risk estimates for patients undergoing cervical screening. Continuously updatable with current system data, the PCCSM provides a new tool to monitor cervical disease risk in the evolving postvaccination era.

Cervical spine injuries are common and essential diagnostic problem. Diagnostic imaging is necessary for proper and effective treatment. Helical computed tomography (CT) and plain radiography are the basic diagnostic methods in cervical spine injuries. The purpose of this work was the comparison of CT examination of the upper cervical spine (CI-C2) with patients' clinical state. Twenty four patients (17 men and 7 women) were introduced into the study. The most common cause of cervical spine injuries were car accidents (48.5%). CT examination was performed in all patients. Six patients (25%) had multilevel injury, localized at C1-C2 level and in the lower part of cervical spine. The main pathology diagnosed by CT in the studied group was rotatory subluxation (66.6%). Eight patients (33.3%), with rotatory subluxation did not present any abnormalities in neurological examination performed immediately after the admission to the hospital. C1 and/or C2 fractures were diagnosed in 11 patients (45.8%), in some cases (in 3 patients - 12.5%) they were accompanied by rotatory subluxations. CT examination is the basic technique of diagnostic imaging in a case of cervical spine injuries. It enables quick, accurate and precise evaluation of bone structures and surrounding soft tissues. CT also enables multiplanar imaging and 3-dimentional imaging.

Effects of Cervical Kyphosis on Recovery From Dysphagia After Stroke

PubMed Central

2016-01-01

Objective To determine the effects of cervical kyphosis on the recovery of swallowing function in subacute stroke patients. Methods Baseline and 1-month follow-up videofluoroscopic swallowing studies (VFSSs) of 51 stroke patients were retrospectively analyzed. The patients were divided into the cervical kyphosis (Cobb's angle <20°, n=27) and control (n=24) groups. The penetration-aspiration scale (PAS), American Speech-Language-Hearing Association National Outcomes Measurement System swallowing scale (ASHA NOMS), and videofluoroscopic dysphagia scale (VDS) were used to determine the severity of dysphagia. Finally, the prevalence of abnormal VFSS findings was compared between the two groups. Results There were no significant differences in baseline PAS, ASHA NOMS, and VDS scores between the two groups. However, the follow-up VDS scores in the cervical kyphosis group were significantly higher than those in the control group (p=0.04), and a follow-up study showed a tendency towards worse ASHA NOMS scores (p=0.07) in the cervical kyphosis group. In addition, the cervical kyphosis group had a higher occurrence of pharyngeal wall coating in both baseline and follow-up studies, as well as increased aspiration in follow-up studies (p<0.05). Conclusion This study showed that stroke patients who had cervical kyphosis at the time of stroke might have impaired recovery from dysphagia after stroke. PMID:27847711

Patients with idiopathic adult-onset cervical dystonia (CD) experience an abnormal head posture and involuntary muscle contractions. Although the exact areas affected in the central nervous system remain uncertain, impaired functions in systems stabilizing the head and neck are apparent such as the somatosensory and sensorimotor integration systems. The aim of the study is to investigate cervical sensorimotor control dysfunction in patients with CD. Cervical sensorimotor control was assessed by a head repositioning task in 24 patients with CD and 70 asymptomatic controls. Blindfolded participants were asked to reposition their head to a previously memorized neutral head position (NHP) following an active movement (flexion, extension, left, and right rotation). The repositioning error (joint position error, JPE) was registered via 3D motion analysis with an eight-camera infrared system (VICON ® T10). Disease-specific characteristics of all patients were obtained via the Tsui scale, Cervical Dystonia Impact Profile (CDIP-58), and Toronto Western Spasmodic Rating Scale. Patients with CD showed larger JPE than controls (mean difference of 1.5°, p  <   .006), and systematically 'overshoot', i.e. surpassed the NHP, whereas control subjects 'undershoot', i.e. fall behind the NHP. The JPE did not correlate with disease-specific characteristics. Cervical sensorimotor control is impaired in patients with CD. As cervical sensorimotor control can be trained, this might be a potential treatment option for therapy, adjuvant to botulinum toxin injections.

The authors present the case of a 56-year-old right hand-dominant woman who was referred for chronic neck pain and a second opinion regarding a cervical lesion. The patient's pain was localized to the subaxial spine in the midline. She reported a subjective sense of intermittent left arm weakness manifesting as difficulty manipulating small objects with her hands and fingers. She also reported paresthesias and numbness in the left hand. Physical and neurological examinations demonstrated no abnormal findings except for a positive Tinel sign over the left median nerve at the wrist. Electromyography demonstrated bilateral carpal tunnel syndrome with no cervical radiculopathy. Cervical spine imaging demonstrated multilevel degenerative disc disease and a pneumatocyst of the C-5 vertebral body. The alignment of the cervical spine was normal. A review of the patient's cervical imaging studies obtained in 1995, 2007, 2008, and 2010 demonstrated that the pneumatocyst was not present in 1995 but was present in 2007. The lesion had not changed in appearance since 2007. At an outside institution, multilevel fusion of the cervical spine was recommended to treat the pneumatocyst prior to evaluation at the authors' institution. The authors, however, did not think that the pneumatocyst was the cause of the patient's neck pain, and cervical pneumatocysts typically have a benign course. As such, the authors recommended conservative management and repeated MR imaging in 6 months. Splinting was used to treat the patient's carpal tunnel syndrome.

Our goal was to find the clinical value of cervical vestibular evoked myogenic potential (VEMP) in Ménière's disease (MD) and to evaluate whether the VEMP results can be useful in assessing the stage of MD. Furthermore, we tried to evaluate the clinical effectiveness of VEMP in predicting hearing outcomes. The amplitude, peak latency and interaural amplitude difference (IAD) ratio were obtained using cervical VEMP. The VEMP results of MD were compared with those of normal subjects, and the MD stages were compared with the IAD ratio. Finally, the hearing changes were analyzed according to their VEMP results. In clinically definite unilateral MD (n=41), the prevalence of cervical VEMP abnormality in the IAD ratio was 34.1%. When compared with normal subjects (n=33), the VEMP profile of MD patients showed a low amplitude and a similar latency. The mean IAD ratio in MD was 23%, which was significantly different from that of normal subjects (P=0.01). As the stage increased, the IAD ratio significantly increased (P=0.09). After stratification by initial hearing level, stage I and II subjects (hearing threshold, 0-40 dB) with an abnormal IAD ratio showed a decrease in hearing over time compared to those with a normal IAD ratio (P=0.08). VEMP parameters have an important clinical role in MD. Especially, the IAD ratio can be used to assess the stage of MD. An abnormal IAD ratio may be used as a predictor of poor hearing outcomes in subjects with early stage MD.

The debate continues regarding the best management for women with low-grade abnormal cervical cytology attending colposcopy. We compared psychosocial outcomes of alternative management policies in these women. In all, 989 women, aged 20-59 years, with low-grade abnormal cytology, were randomised to immediate large loop excision (LLETZ) or two to four targeted punch biopsies taken immediately with recall for LLETZ if these showed cervical intra-epithelial neoplasia 2/3. At 6 weeks after the last procedure, women completed the hospital anxiety and depression scale (HADS) and the impact of event scale (IES). At 12, 18, 24 and 30 months post recruitment, women completed the HADS and process outcome specific measure (POSM). Prevalence of significant depression (≥ 8), significant anxiety (≥ 11) and distress (≥ 9) and median POSM scores were compared between arms. Multivariate odds ratios (ORs) for immediate LLETZ vs biopsy and recall were computed. Over the entire follow-up, there was no significant difference between arms in cumulative prevalence or risk of significant depression (OR=0.78, 95% CI 0.52-1.17) or significant anxiety (OR=0.83, 95% CI 0.57-1.19). At 6 weeks post procedure, distress did not differ significantly between arms. At later time points, 8-11% had significant depression and 14-16% had significant anxiety but with no differences between arms. The POSM scores did not differ between the arms. There is no difference in long- or short-term psychosocial outcomes of immediate LLETZ and punch biopsies with selective recall.

Although colposcopy is the leading follow-up option for women with abnormal cervical cytology, little is known about its psychological consequences. We performed a systematic review to examine: (1) what, if any, are the adverse psychological outcomes following colposcopy and related procedures; (2) what are the predictors of adverse psychological outcomes post-colposcopy; and (3) what happens to these outcomes over time. Five electronic databases (PubMed, PsychINFO, CINAHL, Web of Science, Scopus) were searched for studies published in English between January 1986 and February 2014. Eligible studies assessed psychological wellbeing at one or more time-points post-colposcopy. Two reviewers independently screened titles and abstracts. Full texts of potentially eligible papers were reviewed. Data were abstracted from, and a quality appraisal performed of, eligible papers. Twenty-three papers reporting 16 studies were eligible. Colposcopy and related procedures can lead to adverse psychological outcomes, particularly anxiety. Ten studies investigated predictors of adverse psychological outcomes; management type and treatment had no impact on this. Seven studies investigated temporal trends in psychological outcomes post-colposcopy; findings were mixed, especially in relation to anxiety and distress. Studies were methodologically heterogeneous. Follow-up investigations and procedures for abnormal cervical cytology can cause adverse psychological outcomes among women. However, little is known about the predictors of these outcomes or how long they persist. There is a need for a more standardised approach to the examination of the psychological impact of colposcopy, especially longer-term outcomes. Follow-up investigations for abnormal cervical cytology can cause adverse psychological outcome among women. © 2015 Royal College of Obstetricians and Gynaecologists.

Cervical cancer is the fourth most common malignancy in women worldwide. However, screening with human papillomavirus (HPV) molecular tests holds promise for reducing cervical cancer incidence and mortality in low- and middle-income countries. The performance of the Abbott RealTime High-Risk HPV test (AbRT) was evaluated in 83 cervical smear specimens and compared with a conventional nested PCR coupled to high-throughput sequencing (HTS) to identify the amplicons. The AbRT assay detected at least one HPV genotype in 44.57% of women regardless of the grade of cervical abnormalities. Except for one case, good concordance was observed for the genotypes detected with the AbRT assay in the high-risk HPV category determined with HTS of the amplicon generated by conventional nested PCR. The AbRT test is an easy and reliable molecular tool and was as sensitive as conventional nested PCR in cervical smear specimens for detection HPVs associated with high-grade lesions. Moreover, sequencing amplicons using an HTS approach effectively identified the genotype of the hrHPV identified with the AbRT test.

Cervical spine anomalies in Menkes disease: a radiologic finding potentially confused with child abuse.

Menkes disease is an X-linked recessive disorder of copper transport caused by mutations in ATP7A, a copper-transporting ATPase. Certain radiologic findings reported in this condition overlap with those caused by child abuse. However, cervical spine defects simulating cervical spine fracture, a known result of nonaccidental pediatric trauma, have not been reported previously in this illness. To assess the frequency of cervical spine anomalies in Menkes disease after discovery of an apparent C2 posterior arch defect in a child participating in a clinical trial. We examined cervical spine radiographs obtained in 35 children with Menkes disease enrolled in a clinical trial at the National Institutes of Health Clinical Center. Four of the 35 children with Menkes disease had apparent C2 posterior arch defects consistent with spondylolysis or incomplete/delayed ossification. Defects in C2 were found in 11% of infants and young children with Menkes disease. Discovery of cervical spine defects expands the spectrum of radiologic findings associated with this condition. As with other skeletal abnormalities, this feature simulates nonaccidental trauma. In the context of Menkes disease, suspicions of child abuse should be considered cautiously and tempered by these findings to avoid unwarranted accusations.

The optoelectronic method is one of the most promising concepts of biophysical program of the diagnostics of CIN and cervical cancer. Objectives of the work are evaluation of sensitivity and specificity of the optoelectronic method in the detection of CIN and cervical cancer. The paper shows correlation between the pNOR number and sensitivity/specificity of the optoelectronic method. The study included 293 patients with abnormal cervical cytology result and the following examinations: examination with the use of the optoelectronic method — Truscreen, colposcopic examination, and histopathologic biopsy. Specificity of the optoelectronic method for LGSIL was estimated at 65.70%, for HGSIL and squamous cell carcinoma of cervix amounted to 90.38%. Specificity of the optoelectronic method used to confirm lack of cervical pathology was estimated at 78.89%. The field under the ROC curve for the optoelectronic method was estimated at 0.88 (95% CI, 0.84-0.92) which shows high diagnostic value of the test in the detection of HGSIL and squamous cell carcinoma. The optoelectronic method is characterised by high usefulness in the detection of CIN, present in the squamous epithelium and squamous cell carcinoma of cervix.

Human papilloma virus (HPV) causes cervical cancer in women and approximately 700 deaths have been reported annually in Sri Lanka due to this cancer. Despite, attempts have not been made to investigate the prevalence of HPV amongst Sri Lankan women with normal cytology. In this study, a polymerase chain reaction based assay was set up to detect HPV in both normal and abnormal cytology and the positive samples were then tested for the genotypes, HPV 16 and HPV 18 as they have been identified as the high-risk types associating with cervical cancer. Eighty-four (number = 84) clinical samples (age range 27-69) analyzed in this study indicated that the prevalence of HPV, regardless of cytological abnormalities was 15.5%, (n = 13, 95% class interval ± 7.7) while it was 100% (n = 3) for those with abnormal cytology. Association of HPV 16 and HPV 18 among the abnormal cytology was 0 and 50% (n = 1), respectively and further, the prevalence of HPV 16 and HPV 18 in women was found to be 3.6% (n = 3, 95% CI ± 4.0) and 2.4% (n = 2, 95% CI ± 3.3), respectively. Moreover, age wise prevalence analysis revealed women of the age of 35-years or more to have higher HPV prevalence. The prevalence of HPV among normal cytology is 12.3% (n = 10, 95% CI ± 7.2) which is similar to the rates in other regions of Asia (China 15.4%; India 10.43%). Finally, higher prevalence of HPV in women of the age of 35-years or more in Sri Lanka, especially with malignant types call for such age group to be screened for proper clinical intervention to be made in reducing the incident of cervical cancers. This is the first report of prevalence of HPV among women with normal cytology in Sri Lanka.

Thirty-one individuals awaiting trial or sentencing for murder or undergoing an appeal process requested a neurologic examination through legal counsel. We attempted in each instance to obtain EEG, MRI or CT, and neuropsychological testing. Neurologic examination revealed evidence of "frontal" dysfunction in 20 (64.5%). There were symptoms or some other evidence of temporal lobe abnormality in nine (29%). We made a specific neurologic diagnosis in 20 individuals (64.5%), including borderline or full mental retardation (9) and cerebral palsy (2), among others. Neuropsychological testing revealed abnormalities in all subjects tested. There were EEG abnormalities in eight of the 20 subjects tested, consisting mainly of bilateral sharp waves with slowing. There were MRI or CT abnormalities in nine of the 19 subjects tested, consisting primarily of atrophy and white matter changes. Psychiatric diagnoses included paranoid schizophrenia (8), dissociative disorder (4), and depression (9). Virtually all subjects had paranoid ideas and misunderstood social situations. There was a documented history of profound, protracted physical abuse in 26 (83.8%) and of sexual abuse in 10 (32.3%). It is likely that prolonged, severe physical abuse, paranoia, and neurologic brain dysfunction interact to form the matrix of violent behavior.

Given the importance of epidemiological studies on the prevalence of human papilloma virus (HPV) and its subtypes to plan more effective strategies for cervical cancer prevention, the aim of this study was to determine the prevalence of HPV in women with cervical intraepithelial neoplasia and cancer in Isfahan. In this descriptive cross-sectional study, women referred to oncology clinic of Shahid Beheshti Hospital because of abnormal cytology of their cervices within the last year were studied. The 2001 Bethesda system was used for histologic classification. The distribution of different pathologies was as follows: squamous cell carcinoma (SCC) 34.7%, low-grade squamous intraepithelial lesions (LSIL) 30.5%, high-grade squamous intraepithelial lesions (HSIL) 22.8%, atypical squamous cell of undetermined significance (ASCUS) 8.4%, and adenocarcinoma (AC) 3.3%. There was no case of atypical glandular of undetermined significance or cases of adenocarcinoma associated with an early lesion. The presence of HPV infection and its subtypes including HPV 16, 18, 6 and 11 was assessed in different cytological categories of cervical neoplasia, by using polymerase chain reaction method. During this study, 130 patients were studied. Their median age was 52 years (range 29-73 years). HPV was detected in 118/130 patients (90.8%) with abnormal cervical cytology. The prevalence of positive HPV samples was 97.6, 80, 93.1, 92.3, and 66.6% in cases with SCC, AC, HSIL, LSIL, and ASCUS, respectively (P < 0.05 between SCC and ASCUS, HSIL and ASCUS, and LSIL and ASCUS). Out of 118 cases with positive HPV, 98 (83.1%) were positive for multiple HPV types 16, 18, and 11 or 6. The distribution of studied HPV subtypes among women with positive HPV was as follows: 49.1% for both types 16 and 18, 10.1% for type 16, 1.69% for type 18 and 22% for type 11 or 6. The prevalence of HPV type 16 was not significantly different in various cytological categories of cervical neoplasia (P > 0.05). The prevalence of HPV type 16 and 18 was significantly higher than the HPV type 11 or 6 in cervical neoplastic lesions (P < 0.05). The results of this research indicated the high prevalence of HPV infection in all categories of cervical neoplasia. This emphasizes the importance of HPV screening and vaccination programs. In order to assess more effective screening programs in Isfahan and evaluate the cost-effectiveness of vaccination programs, further population-based prospective studies are required.

To determine whether Contraction Induced H Reflexes (CIHR) can accurately detect cervical radiculopathy. Comparison of CIHR results with Needle Electromyography at academic outpatient Electromyography/Nerve Conduction laboratories. Participants were all patients over 18 with a needle electromyography diagnosis of cervical radiculopathy. Patients were tested for CIHR in at least two upper extremity muscles in electromyographically proven myotomes bilaterally. Patients were requested to perform a moderate contraction while stimulus was applied proximally (elbow or Erb's point). Outcome measures included H Reflex onset latency and side-to-side latency differences. These were compared against previously established normal values. Overall, 10 of 15 patients who met criteria for cervical radiculopathy showed CIHR abnormalities (sensitivity = 67%; 95% confidence interval, 43-91). Counting each side and level separately, CIHR identified 16/27 radiculopathies (sensitivity = 59.2%; 95% confidence interval, 40.6-77.8). Contraction Induced H Reflexes identified 1 possible radiculopathy not seen on electromyography (specificity = 98%; 95% confidence interval, 95-100). Contraction induced H Reflexes have a sensitivity and specificity for cervical radiculopathy similar to the resting Gastroc-Soleus H Reflex.

Traditionally, the pathophysiology of cervical dystonia has been regarded mainly in relation to neurochemical abnormities in the basal ganglia. Recently, however, substantial evidence has emerged for cerebellar involvement. While the absence of neurological “cerebellar signs” in most dystonia patients may be considered at least provoking, there are more subtle indications of cerebellar dysfunction in complex, demanding tasks. Specifically, given the role of the cerebellum in the neural representation of time, in the millisecond range, dysfunction to this structure is considered to be of greater importance than dysfunction of the basal ganglia. In the current study, we investigated the performance of cervical dystonia patients on a computer task known to engage the cerebellum, namely, the interception of a moving target with changing parameters (speed, acceleration, and angle) with a simple response (pushing a button). The cervical dystonia patients achieved significantly worse results than a sample of healthy controls. Our results suggest that the cervical dystonia patients are impaired at integrating incoming visual information with motor responses during the prediction of upcoming actions, an impairment we interpret as evidence of cerebellar dysfunction.

To study the effect of vertebrae semi-dislocation on the stress distribution in facet joint and interuertebral disc of patients with cervical syndrome using three dimensional finite element model. A patient with cervical spondylosis was randomly chosen, who was male, 28 years old, and diagnosed as cervical vertebra semidislocation by dynamic and static palpation and X-ray, and scanned from C(1) to C(7) by 0.75 mm slice thickness of CT. Based on the CT data, the software was used to construct the three dimensional finite element model of cervical vertebra semidislocation (C(4)-C(6)). Based on the model,virtual manipulation was used to correct the vertebra semidislocation by the software, and the stress distribution was analyzed. The result of finite element analysis showed that the stress distribution of C(5-6) facet joint and intervertebral disc changed after virtual manipulation. The vertebra semidislocation leads to the abnormal stress distribution of facet joint and intervertebral disc.

To assess the percentage of squamous intraepithelial lesions (SILs) in the atypical squamous cells of undetermined significance (ASCUS) cytologic diagnosis. From January 1994 to December 1995, 421 cervical Pap smears with a diagnosis of ASCUS were followed with cervical biopsies within three months. The ASCUS cytologic diagnosis was correlated with the histologic findings and stratified according to age group, previous abnormal history and cell type of ASCUS (squamoid vs. metaplastic). Histologic diagnosis showed that of ASCUS diagnoses, 13% were normal, 34% were reactive, 4.8% were atypical, 43% were low grade SIL, 4% were high grade SIL, 1% were carcinoma in situ, and none were invasive lesions. The patients in the youngest group, up to 25 years, demonstrated the highest percentage of SIL. Patients with a previous abnormal gynecologic history showed a higher percentage of SIL than those without an abnormal history. SILs were observed in 51.5% of squamoid ASCUS and 36.5% of metaplastic ASCUS. Forty-eight percent of females having an ASCUS diagnosis on Pap smears had SIL and thus a preneoplastic lesion. The highest percentage of SIL was found in females 25 years and younger. Our findings suggest that an ASCUS diagnosis warrants ongoing follow-up.

A negative computed tomographic (CT) scan may be used to rule out cervical spine (c-spine) injury after trauma. Loss of lordosis (LOL) is frequently found as the only CT abnormality. We investigated whether LOL should preclude c-spine clearance. All adult trauma patients with isolated LOL at our Level I trauma center (February 1, 2011 to May 31, 2012) were prospectively evaluated. The primary outcome was clinically significant injury on magnetic resonance imaging (MRI), flexion-extension views, and/or repeat physical examination. Of 3,333 patients (40 ± 17 years, 60% men) with a c-spine CT, 1,007 (30%) had isolated LOL. Among 841 patients with a Glasgow Coma Scale score of 15, no abnormalities were found on MRI, flexion-extension views, and/or repeat examinations, and all collars were removed. Among 166 patients with Glasgow Coma Scale less than 15, 3 (.3%) had minor abnormal MRI findings but no clinically significant injury. Isolated LOL on c-spine CT is not associated with a clinically significant injury and should not preclude c-spine clearance. Copyright © 2015 Elsevier Inc. All rights reserved.

A connection between infections with a highly oncogenic type of human papilloma virus and the development of cervical intraepithelial neoplasia and preinvasive cervical cancer has been proven both experimentally and clinically. The period after which persistent virus infection will lead to the development of precancerous and invasive lesions is dependent on, among others, the HPV genotype. The oncogenic types of human papilloma virus destabilize the genome of an infected cell and thus initiate the carcinogenesis process. The aim of this work was to analyze the frequency of occurrence of different oncogenic HPV genotypes among women with abnormal cytological smears and the correlation of this data with the degree of cervical intraepithelial neoplasia exacerbation. The sample consisted of 75 women of child-bearing age (16-43 years old) with an abnormal cytological smear and positive test identifying an infection with an oncogenic type of human papilloma virus. In every case histopathological verification, aimed at excluding pathologies in the endocervix, was conducted using a colposcopy with guided biopsy and cervix abrasion. The authors found that the frequency of occurrence of different HPV genotypes of the groups of cytological diagnoses ASC-US, LSIL and HSIL do not differ statistically (p = 0.57). However, what is noteworthy is the more common occurrence of HPV 16 in type LSIL lesions (45.45%) and HPV 18 of a more advanced type HSIL (37.50%) pathology. Through the verification of the cytology results with histopathological diagnosis of the above groups the authors obtained statistically significant differences (p < 0.001) of individual pathological states. When regarding cytological HSIL diagnosis, CIN 1 was never diagnosed, while in other cytological groups cervical intraepithelial neoplasia of a low degree constituted over 40%. Analogically about 40% of HSIL diagnoses after histopathological verification turned out to be cancer of a pre-invasive state (CIS/AIS), the presence of which was not revealed by ASC-US and LSIL. What is more, CIN2/3 diagnosis was less frequent in the ASC-US cytological group than in the other two groups. While analyzing a share of other than HPV 16 and HPV 18 oncogenic types of human papilloma virus, the authors found that the most common were HPV 31, 45 and 33. In CIN 1 and CIN 2 their share was over 60%. In CIS/AIS type pathologies, no other types of human papilloma virus than HPV 16 and HPV 18 were shown. Positive results of DNA HR HPV testing of women with abnormal cytology results identified a risk group for the development of cervical cancer. No statistically significant differences of the frequency of HPV 16 and HPV 18 type occurrences were found in analyzed groups with cytological and histopathological diagnoses.

Most Thai people believe that health care providers have a lower risk of any disease than their patients. This belief may lull Thai health care providers into accepting the false belief that they are at a lower risk of having the precancerous conditions that lead to cervical cancer. This study compares the prevalence of abnormal Pap smears from health care providers (HC) and non health care providers (NHC) by using the standard liquid-based Pap smear processing at Thammasat University Hospital's pathology department, Thailand. Both health care providers (HC) and non health care providers (NHC) were patients at the outpatient clinic, Thammasat University Hospital. They were screened for cervical cancer by using liquid-based Pap smear (LBP). Cytological diagnoses and specimen adequacy were classified using the Bethesda system 2001. All subjects who had abnormal cytology more than atypical squamous cells or atypical glandular cells were counseled to have performed a colposcopic directed biopsy for confirmation of pathology. A total of 250 liquid-base Pap smears were processed and evaluated at the Gynecology clinic, Thammasat University Hospital from April 2008 to May 2008. The groups of HC and NHC consisted of 122 and 128 women, respectively. In general, both the HC and NHC groups were similar in their age, religion, income and education level distributions. The range of ages was between 16 and 75 years, with the mean age equal to 40.2 +/- 10.5 years. Prevalence of abnormal Pap smears was 9.8% in HC and 9.4% in NHC (p-value = 0.90). HC showed atypical change (ASC, AGC), low-grade squamous intraepithelial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) at 0.8%, 1.6% and 7.4%, respectively. NHC had an incidence of atypical change, LSIL and HSIL at 0.8%, 0.8% and 7.8%. HC had an equal incidence of abnormal Pap smears prevalence to NHC. Further, the percentage of HC and NHC groups with histological confirmed cervical intraepithelial neoplasia (CIN) 1 were not significantly different (4.92% vs. 6.25%, p-value = 0.70), likewise CIN 2/3 (1.64% vs. 1.56%, p-value = 1.00). According to our study the rate of abnormal Pap smears observed in both health care providers and clients was essentially the same. The prevalence of abnormal Pap smears in health care providers was statistically equivalent to that in their clients.

To analyze the relationship between position of head, cervical curvature type and associated cervical balance parameters in a neutral looking-forward posture. Cervical lateral X-rays of 60 patients with cervical spondylosis were selected from January to December 2015. There were 22 males and 38 females with an average age of (35.5±10.9) years old. The measured parameters included cervical curvature type, McGregor slope, C2 lower end plate slope, T1 slope, center of gravity to C7 sagittal vertical offset (CG-C7 SVA), and C2 to C7 sagittal vertical offset (C2-C7 SVA). The parameters were analyzed using Spearman correlation. The cervical curvature type was significantly correlated with C2 lower endplate slope, C0-C2 angle (total degree of C2 lower endplate slope plus McGregor slope), CG-C7 SVA and T1 slope ( P <0.05), but it was not significantly correlated McGregor slope ( P >0.05). C2 lower endplate slope and C2-C7 SVA (r=0.87) were significantly ( P <0.05) correlated with CG-C7 SVA ( P <0.05). There was certain some relationship among position of head, cervical curvature type and associated cervical balance parameters in a neutral looking-forward posture. The center of gravity of the head would backwards shift following faced upward. A position of extension with posterior-shifting of the head would suggest that it may be accompanied with a relatively normal lordosis of the cervical spine. Some patients with abnormal curvature showed slightly bended head in the natural posture. Health education toward these people would be meaningful to restore the balance of their neck.

Balancing uncertainty and acceptance: understanding Chinese women's responses to an abnormal cervical smear result.

The aims of this study were to examine the responses of Hong Kong Chinese women receiving an abnormal smear result and to compare any differences in responses depending on the diagnosis of the abnormal smear. The implementation of cervical screening programmes has resulted in an increasing number of women receiving an abnormal smear result requiring cytological surveillance or referral for colposcopy. Evidence suggests that women frequently misunderstood such results, believing that they already have cancer. However, little is known about the responses of Chinese women in this situation. An exploratory qualitative study. Face-to-face semi-structured tape-recorded interviews were undertaken with 66 women sampled opportunistically from an urban centre of a major non-governmental service provider. Amongst this sample, 22 women required cytological surveillance, 20 required treatment for vaginitis and 24 were referred for colposcopy. Thematic analysis was undertaken of the translated interviews within and across groups to identify categories and themes illustrating women's responses to an abnormal smear result. An important difference in the comparison of the data sets was that of women's understanding of the cause of the abnormal result. Women with vaginitis understood the cause of their abnormality, whereas those in the other groups remained unclear about their abnormality, generating feelings of fear and uncertainty. Trust in practitioners influenced women's acceptance of the result. Although responses of Chinese women are similar to those in other population groups, with those referred for colposcopy experiencing greater anxiety than those undergoing cytological surveillance, balancing feelings of uncertainty and acceptance influenced Chinese women's responses to their abnormal results and allowed them to make sense of their result in their everyday life. Trust in the practitioner was essential to the acceptance of their result. Such findings highlight implications for nursing practice, in particular developing information-giving strategies and targeted information to help women manage feelings of uncertainty. The importance of trusting professional relationships in determining women's acceptance of an abnormal result is also highlighted. The findings suggest nurses working with Chinese women should consider the underlying influence of culture on women's beliefs and actions.

A noninvasive, novel assessment that detected potential photoreceptor abnormalities in the retina overlying the choroidal lesion and adjacent retina is presented. These findings may help current clinical evaluation to monitor structural damage to the outer retina and possibly justify earlier intervention in borderline cases. Future research is warranted to recognize full potential of this imaging modality. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:354-357.]. Copyright 2017, SLACK Incorporated.

A review of smoking cessation services in women attending colposcopy clinics in Scotland.

2012-02-01

The most common reason for women being referred to colposcopy clinics is an abnormal smear suggesting pre-cancerous change within the cervix. It has been demonstrated that in women with low-grade lesions, smoking cessation led to a reduction in size of the cervical lesion over a 6-month period. Smoking is also recognised as an independent risk factor for treatment failure of cervical intraepithelial neoplasia. As 'stop smoking' services have become an integral part of the colposcopy clinic at St John's Hospital, Livingston, a national survey was undertaken. The aim of the survey was to establish what smoking cessation information, advice and support is available in colposcopy clinics throughout Scotland, and if staff had attended standardised training on raising the issue of smoking. The study demonstrated that 52% of colposcopy clinics in Scotland always establish smoking status but only 37% of clinics discuss the benefits of smoking cessation in relation to abnormal cervical smears. There was inaccurate and inconsistent written and verbal advice given on the benefits of cessation and whether women should cut down or stop smoking completely. The majority of staff had not attended standardised training on how to raise the issue of smoking and very few clinics have established referral pathways for smoking cessation support.

A 36 year old man with a history of testicular germ cell tumour presented six months after bilateral orchidectomy with progressive amnesia, irritability, vertical gaze palsy, and generalised seizures. Eight months after initial onset of symptoms, he demonstrated a head drop with muscular atrophy of the upper limbs, shoulder girdle, and posterior neck. He reported no sensory disturbances and his sensory examination was normal. The overall clinical presentation was consistent with motor neurone disease. Cerebrospinal fluid analysis revealed mild pleocytosis and increased protein concentration. Serum and cerebrospinal fluid were positive for the anti-Ma2 antibody by western blot analysis and immunostaining. Abnormal high signal in the grey matter was noted in the cervical spinal cord and brain by T2 weighted magnetic resonance imaging (MRI). The patient was treated with corticosteroids, intravenous immunoglobulin, and antiepileptic medication. The patient improved clinically and symptom progression ceased after initiation of treatment. There was complete resolution of the abnormal brain MRI lesions; however, the cervical spinal cord MRI lesion and muscular atrophy remained unchanged. It is suggested that the anti-Ma2 antibody is involved not only in encephalitis, but may also play a role in the cervical spinal cord lesions resulting in a motor neurone disease-like presentation.

Pemphigus vulgaris (PV) is a rare mucocutaneous disease caused by the abnormal production of antibodies against epithelial cell surface glycoproteins, resulting in loss of cell adhesion and intraepithelial blister formation. Cervical involvement in PV has been poorly reported, and there is little information regarding the criteria about consequential cytological changes identified in a Papanicolaou-stained cervicovaginal smear (Pap smear). Here, we report a case of PV manifesting in the cervix as well as the difficulty associated with the cytomorphological identification and interpretation of acantholytic cells. This case involved a 40-year-old patient with no history of Pap test abnormalities and no prior diagnosis of PV. In the cytological assessment, cells were identified both in isolation and in clusters that exhibited round nuclei of increased volume, inconspicuous nucleoli, and perinuclear halos. The patient underwent a cervical biopsy that revealed vesiculobullous lesions and morphological pattern consistent with PV. A skin biopsy confirmed this diagnosis. We concluded that knowledge of PV cytomorphology is important because difficulties associated with the identification and interpretation of acantholytic cells might be responsible for false positive diagnoses of cervical neoplasia. However, a suspected diagnosis of PV is possible if the cytological findings are carefully correlated with the clinical data. © 2015 Wiley Periodicals, Inc.

Cervical cancer has remained, until now, as a serious public health problem in developing countries. The most common method of screening is the Pap test or cytology. When abnormalities are reported in the result, the patient is referred to a dysplasia clinic for colposcopy. During this test, a solution of acetic acid is applied, which produces a color change in the tissue and is known as acetowhitening phenomenon. This reaction aims to obtaining a sample of tissue and its histological analysis let to establish a final diagnosis. During the colposcopy test, digital images can be acquired to analyze the behavior of the acetowhitening reaction from a temporal approach. In this way, we try to identify precursor lesions of cervical cancer through a process of automatic classification of acetowhite temporal patterns. In this paper, we present the performance analysis of three classification methods: kNN, Naïve Bayes and C4.5. The results showed that there is similarity between some acetowhite temporal patterns of normal and abnormal tissues. Therefore we conclude that it is not sufficient to only consider the temporal dynamic of the acetowhitening reaction to establish a diagnosis by an automatic method. Information from cytologic, colposcopic and histopathologic disciplines should be integrated as well.

Malignant mixed Mullerian tumour is a rare gynaecological tumour commonly presenting with vaginal bleeding, abdominal pain or mass in the uterine cavity, cervix or vagina. The neoplasms are commonly seen in postmenopausal women although it has been observed in younger women. Ovaries and the corpus of the uterus are commonly involved, whereas involvement of the cervix and vagina is rare. A 37 year-old Tanzania lady para 7 with a previous history of two genital polypectomies presented with history of recurrent vaginal mass which was associated with abnormal vaginal bleeding and foul smelling discharge. Vaginal examination revealed a prolapsed uterus with giant fungating cervical mass which was ulcerated, friable, and bled easily on touch. Impression was grade three uterine prolapse with infected cervical polyp/cervical sarcoma. Excision of the tumour through trans-vaginal hysterectomy was performed, no lymphadenopathy was found, no adnexa abnormalities, and no involvement of the vaginal wall. Histological diagnosis of Malignant mixed Mullerian tumour of the cervix was made. Patient recovery was unremarkable; however she was lost to follow up. The patient's mass was initially suspected to be prolapsed uterus with decubitus ulcer but the histological results were of a malignant condition. Lack of clear management guidelines for some rare mixed tumours remains a challenge for clinicians in low resource settings.

We investigated a typical cerebellar function (anticipatory movement control) in patients with cervical dystonia (CD) with and without tremor. Twenty patients with CD, with and without tremor, and 17 healthy controls were required to catch balls of different load: 15 trials with a light ball, 25 trials with a heavy ball (adaptation) and 15 trials with a light ball (post-adaptation). Arm movements were recorded using a motion capture system. We evaluated: (i) the anticipatory adjustment (just before the impact); (ii) the extent and rate of the adaptation (at the impact) and (iii) the aftereffect in the post-adaptation phase. The anticipatory adjustment was reduced during adaptation in CD patients with tremor respect to CD patients without tremor and controls. The extent and rate of adaptation and the aftereffect in the post-adaptation phase were smaller in CD with tremor than in controls and CD without tremor. Patients with cervical dystonia and tremor display an abnormal predictive movement control. Our findings point to a possible role of cerebellum in the expression of a clinical phenotype in dystonia.

Heterotopic gastric mucosa occurs as a flat island of red mucosa in the proximal third of the esophagus where it gives rise to the cervical inlet patch. The aims of this study were to investigate the esophageal motility pattern and 24-h pH profiles of patients with cervical inlet patch. Thirty patients (16 women, mean age: 44.9 years, range: 23-72) diagnosed as having heterotopic gastric mucosa in the cervical esophagus with upper gastrointestinal symptoms had undergone esophageal motility testing and 24-h pH monitorisation with a double-channel pH probe. Manometric investigation was abnormal in 7 patients (non-specific esophageal motor disorder in 4 patients, esophageal hypomotility in 1 patient, and hypotensive LES in 2 patients). Pathological acid reflux (pH<4) was found in 9 (30%) of 30 heterotopic gastric mucosa patients during pH monitorisation from the distal probe. Pathological acid reflux in the proximal esophagus (percentage of total time of pH<4) was seen in four of these nine patients. Only four of the 30 patients (13.3%) presented with "acid independent episodes" during the 24-h esophageal pH monitorisation. Manometric investigation and 24-h pH monitorisation revealed that some of the patients with HGM have signs of esophageal motor dysfunction and "acid independent episodes" from the patches. These abnormalities may be responsible for some of the symptoms of HGM patients. Copyright 2009 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

A clinical decision support system (CDSS) for cervical cancer screening identifies patients due for routine cervical cancer screening. Yet, high-risk patients who require more frequent screening or earlier follow-up to address past abnormal results are not identified. We aimed to assess the effect of a complex CDSS, incorporating national guidelines for high-risk patient screening and abnormal result management, its implementation to identify patients overdue for testing, and the outcome of sending a targeted recommendation for follow-up. At three primary care clinics affiliated with an academic medical center, a reminder recommending an appointment for Papanicolaou (Pap) testing or Pap and human papillomavirus cotesting was sent to high-risk women aged 18 through 65 years (intervention group) identified by CDSS as overdue for testing. Historical control patients, who did not receive a reminder, were identified by CDSS 1 year before the date when reminders were sent to the intervention group. Test completion rates were compared between the intervention and control groups through a generalized estimating equation extension. Across the three sites, the average completion rate of recommended follow-up testing was significantly higher in the intervention group at 23.7% (61/257) than the completion rate at 3.3% (17/516) in the control group (p < 0.001). A CDSS with enhanced capabilities to identify high-risk women due for cervical cancer testing beyond routine screening intervals, with subsequent patient notification, has the potential to decrease cervical precancer and cancer by improving adherence to guideline-compliant follow-up and needed treatment.

We describe an innovative single-stage reduction and stabilization technique using modern cervical instrumentation. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination. Craniocervical junction abnormalities, including atlantoaxial instability and progressive basilar invagination, are relatively common phenomenon in Down's syndrome patients, and can lead to chronic progressive neurologic deficits, catastrophic injury, and death. This patient population also can be a difficult one in which to perform successful stabilization and fusion. We reviewed the records and films on 2 children with Down's syndrome and atlantoaxial instability who had undergone prior occipital-cervical fusion and then presented with symptomatic progressive basilar invagination due to atlantoaxial displacement. In both cases, the children had progressive symptoms of spinal cord and brain stem compression. Multiple approaches for surgical correction, including preoperative traction and transoral odontoid resection, were considered, but ultimately it was elected to perform a single stage posterior operation. In both patients, we performed fusion takedown, intraoperative realignment with reduction of the basilar invagination, and stabilization using modern occipito-cervical instrumentation. In both children, excellent cranio-cervical realignment was achieved; along with successful fusion and improvement in clinical symptoms. In this article we will discuss the clinical cases and review the background of craniocervical junction abnormalities in Down's syndrome patients. We hypothesis modern instrumentation has made more aggressive surgical corrections possible and has reduced the need for transoral resection of the odontoid and traction reduction in children with basilar invagination.

Increasing knowledge concerning carcinogenesis within cervical epithelium has forced us to make continues modifications of cytology classification of the cervical smears. Eventually, new descriptions of the submicroscopic cytomorphological abnormalities have enabled the implementation of Bethesda System which was meant to take place of the former Papanicolaou classification although temporarily both are sometimes used simultaneously. The aim of this study was to compare results of these two classification systems in the aspect of diagnostic accuracy verified by further tests of the diagnostic algorithm for the cervical lesion evaluation. The study was conducted in the group of women selected from general population, the criteria being the place of living and cervical cancer age risk group, in the consecutive periods of mass screening in Podlaski region. The performed diagnostic tests have been based on the commonly used algorithm, as well as identical laboratory and methodological conditions. Performed assessment revealed comparable diagnostic accuracy of both analyzing classifications, verified by histological examination, although with marked higher specificity for dysplastic lesions with decreased number of HSIL results and increased diagnosis of LSILs. Higher number of performed colposcopies and biopsies were an additional consequence of TBS classification. Results based on Bethesda System made it possible to find the sources and reasons of abnormalities with much greater precision, which enabled causing agent treatment. Two evaluated cytology classification systems, although not much different, depicted higher potential of TBS and better, more effective communication between cytology laboratory and gynecologist, making reasonable implementation of The Bethesda System in the daily cytology screening work.

Genetic and metabolic studies have been done on a large kindred in which several males are affected by a syndrome of borderline mental retardation and abnormal behavior. The types of behavior that occurred include impulsive aggression, arson, attempted rape, and exhibitionism. Analysis of 24-hour urine samples indicated markedly disturbed monoamine metabolism. This syndrome was associated with a complete and selective deficiency of enzymatic activity of monoamine oxidase A (MAOA). In each of five affected males, a point mutation was identified in the eighth exon of the MAOA structural gene, which changes a glutamine to a termination codon. Thus, isolated completemore » MAOA deficiency in this family is associated with a recognizable behavioral phenotype that includes disturbed regulation of impulsive aggression.« less

Sensitivity for detection of precancers at colposcopy and reassurance provided by a negative colposcopy are in need of systematic study and improvement. We sought to evaluate whether selecting the appropriate women for multiple targeted cervical biopsies based on screening cytology, human papillomavirus testing, and colposcopic impression could improve accuracy and efficiency of cervical precancer detection. In all, 690 women aged 18-67 years referred to colposcopy subsequent to abnormal cervical cancer screening results were included in the study (ClinicalTrials.gov: NCT00339989). Up to 4 cervical biopsies were taken during colposcopy to evaluate the incremental benefit of multiple biopsies. Cervical cytology, human papillomavirus genotyping, and colposcopy impression were used to establish up to 24 different risk strata. Outcomes for the primary analysis were cervical precancers, which included p16 + cervical intraepithelial neoplasia 2 and all cervical intraepithelial neoplasia 3 that were detected by colposcopy-guided biopsy during the colposcopy visit. Later outcomes in women without cervical intraepithelial neoplasia 2 + at baseline were abstracted from electronic medical records. The risk of detecting precancer ranged from 2-82% across 24 strata based on colposcopy impression, cytology, and human papillomavirus genotyping. The risk of precancer in the lowest stratum increased only marginally with multiple biopsies. Women in the highest-risk strata had risks of precancer consistent with immediate treatment. In other risk strata, multiple biopsies substantially improved detection of cervical precancer. Among 361 women with cervical intraepithelial neoplasia <2 at baseline, 195 (54%) had follow-up cytology or histology data with a median follow-up time of 508 days. Lack of detection of precancer at initial colposcopy that included multiple biopsies predicted low risk of precancer during follow-up. Risk assessment at the colposcopy visit makes identification of cervical precancers more effective and efficient. Not finding precancer after a multiple-biopsy protocol provides high reassurance and allows releasing women back to regular screening. Published by Elsevier Inc.

The aims of this study were to investigate the correlation of the findings of multiple median and ulnar F-wave variables and magnetic resonance imaging examinations in the prediction of cervical radiculopathy. The data of 68 patients who underwent both nerve conduction studies of the upper extremities and cervical spine magnetic resonance imaging within 3 mos of the nerve conduction studies were retrospectively reviewed and reinterpreted. The associations between multiple median and ulnar F-wave variables (including persistence, chronodispersion, and minimal, maximal, and mean latencies) and magnetic resonance imaging evidence of lower cervical spondylotic radiculopathy (i.e., C7, C8, and T1 radiculopathy) were investigated. Patients with lower cervical radiculopathy exhibited reduced right median F-wave persistence (P = 0.011), increased right ulnar F-wave chronodispersion (P = 0.041), and a trend toward increased left ulnar F-wave chronodispersion (P = 0.059); however, there were no other consistent significant differences in the F-wave variables between patients with and patients without magnetic resonance imaging evidence of lower cervical radiculopathy. In comparison with normal reference values established previously, the sensitivity and positive predictive value of F-wave variable abnormalities for predicting lower cervical radiculopathy were low. There was a low correlation between F-wave studies and magnetic resonance imaging examinations. The diagnostic utility of multiple F-wave variables in the prediction of cervical radiculopathy was not supported by this study.

The optimal imaging modality for evaluating cervical spine trauma and optimizing management in the pediatric population is controversial. In pediatric populations, there are no well-established guidelines for cervical spine trauma evaluation and treatment. Currently, there is virtually no literature regarding imaging and management of symptomatic pediatric patients who present with cervical spine trauma without high-impact mechanism. This study aims to establish an optimal imaging strategy for this subgroup of trauma patients. We performed a retrospective review of pediatric patients (aged below 18 years) who were admitted to Monash Medical Centre, Melbourne, Australia between July 2011 and June 2015, who did not suffer a high-impact trauma but were symptomatic for cervical spine injury following cervical trauma. Imaging and management strategies were reviewed and results compared. Forty-seven pediatric patients were identified who met the inclusion criteria. Of these patients, 46 underwent cervical spine series (CSS) plain radiograph imaging. Thirty-four cases underwent magnetic resonance imaging (MRI) and 9 patients underwent CT. MRI was able to detect 4 cases of ligamentous injury, which were not seen in CSS imaging and was able to facilitate cervical spine clearance in a further two patients whose CSS radiographs were abnormal. In this study, MRI has a greater sensitivity and specificity when compared to CSS radiography in a symptomatic pediatric low-impact trauma population. Our data call in to question the routine use of CSS radiographs in children.

Cervical dystonia (CD) is a movement disorder characterized by involuntary muscle contractions leading to an abnormal head posture or movements of the neck. Dysfunctions in somatosensory integration are present and previous data showed enlarged postural sway in stance. Postural control during quiet sitting and the correlation with cervical sensorimotor control were investigated. Postural control during quiet sitting was measured via body sway parameters in 23 patients with CD, regularly receiving botulinum toxin treatment and compared with 36 healthy controls. Amplitude and velocity of displacements of the center of pressure (CoP) were measured by two embedded force plates at 1000 Hz. Three samples of 30 s were recorded with the eyes open and closed. Disease-specific characteristics were obtained in all patients by the Tsui scale, Cervical Dystonia Impact Profile (CDIP-58) and Toronto Western Spasmodic Rating Scale (TWSTRS). Cervical sensorimotor control was assessed with an infrared Vicon system during a head repositioning task. Body sway amplitude and velocity were increased in patients with CD compared to healthy controls. CoP displacements were doubled in patients without head tremor and tripled in patients with a dystonic head tremor. Impairments in cervical sensorimotor control were correlated with larger CoP displacements (r s ranged from 0.608 to 0.748). Postural control is impaired and correlates with dysfunction in cervical sensorimotor control in patients with CD. Treatment is currently focused on the cervical area. Further research towards the potential value of postural control exercises is recommended.

The current strategy for timely detection of cervical cancer in young females centres on visualising the cervix when females present with gynaecological symptoms, but is based on expert opinion without an evidence base. To assess visualising the cervix in primary care in young females with gynaecological symptoms. A review of primary care records for females in England aged 20-29 years with cervical cancer (nationwide interview-based study) and in the general population (Clinical Practice Research Datalink database). From primary care records the proportion of females was identified with gynaecological symptoms who had documented cervical examination in the year before diagnosis (cancers) and in 1-year age bands (general population). Of these, the proportion was identified that was then referred for suspected malignancy. Only 39% of young females with cervical cancer had documented examination at symptomatic presentation. Visualisation resulted in referral for suspected malignancy for 18% of those examined (95% confidence interval = 5% to 40%). Very few (<1.7%) symptomatic females in the general population had documented cervical examination. None were referred for suspected malignancy at the time. The sensitivity of cervical examination to detect cancer is very low, highlighting the need for better triage tools for primary care. Until such tools are identified GPs should continue to consider cervical cancer when symptoms persist and the cervix is not obviously abnormal on clinical examination. Further research on additional triage tools such as cervical cytology used as a diagnostic aid is needed urgently. © British Journal of General Practice 2016.

Cervical cancer incidence in western Africa is among the highest in the world. To investigate human papillomavirus (HPV) infection in Guinea, we obtained cervical specimens from 831 women aged 18-64 years from the general population of the capital Conakry and from 77 locally diagnosed invasive cervical cancers (ICC). Human papillomavirus was detected using a GP5+/6+ PCR-based assay. Among the general population, the prevalence of cervical abnormalities was 2.6% by visual inspection and 9.5% by liquid-based cytology. Fourteen of 15 high-grade squamous intraepithelial lesions were visual inspection-negative. Human papillomavirus prevalence was 50.8% (32.1% for high-risk types) and relatively constant across all age groups. Being single or reporting > or =3 sexual partners was significantly associated with HPV positivity. HPV16 was the most common type, both among the general population (7.3%) and, notably in ICC (48.6%). HPV45 (18.6%) and HPV18 (14.3%), the next most common types in ICC, were also more common in ICC than in HPV-positive women with normal cytology from the general population. The heavy burden of HPV infection and severe cervical lesions in Guinean women calls for new effective interventions. Sixty-three per cent of cervical cancers are theoretically preventable by HPV16/18 vaccines in Guinea; perhaps more if some cross-protection exists with HPV45.

Cervical cancer is the commonest cancer among Indian women. High-risk human papilloma virus (HPV) detection holds the potential to be used as a tool to identify women, at risk of subsequent development of cervical cancer. There is a pressing need to identify prevalence of asymptomatic cervical HPV infection in local population. In our study, we explored the prevalence of HPV genotypes and their distribution in women with cervical lesions. Scrape specimens were obtained from 100 women (study group) with cervical abnormalities. HPV was detected with amplicor HPV tests, and the individual genotypes in these specimens were identified by Hybribio Genoarray test kit. Fifty specimens were also collected from females with healthy cervix (control group). The present study also aimed to determine the status of HPV prevalence and its association with different sociodemographic factors. Out of the total number of 100 samples, 10 (10 %) women tested positive for HPV DNA. Among them, HPV 18 was observed in 6, HPV 16 in 2, HPV 52 and HPV 39 in one each. Fifty specimens collected from patients with healthy cervix were not infected with any of the HPV genotype. Our study generates data of HPV prevalence in patients with cervical lesions visiting tertiary care institute. The data generated will be useful for laying guidelines for mass screening of HPV detection, treatment, and prophylaxis.

Background Borderline personality disorder (BPD) is a chronic condition with a strong impact on patients‘ affective,cognitive and social functioning. Neuroimaging techniques offer invaluable tools to understand the biological substrate of the disease. We aimed to investigate gray matter alterations over the whole cortex in a group of Borderline Personality Disorder (BPD) patients compared to healthy controls (HC). Methods Magnetic resonance-based cortical pattern matching was used to assess cortical gray matter density (GMD) in 26 BPD patients and in their age- and sex-matched HC (age: 38±11; females: 16, 61%). Results BPD patients showed widespread lower cortical GMD compared to HC (4% difference) with peaks of lower density located in the dorsal frontal cortex, in the orbitofrontal cortex, the anterior and posterior cingulate, the right parietal lobe, the temporal lobe (medial temporal cortex and fusiform gyrus) and in the visual cortex (p<0.005). Our BPD subjects displayed a symmetric distribution of anomalies in the dorsal aspect of the cortical mantle, but a wider involvement of the left hemisphere in the mesial aspect in terms of lower density. A few restricted regions of higher density were detected in the right hemisphere. All regions remained significant after correction for multiple comparisons via permutation testing. Conclusions BPD patients feature specific morphology of the cerebral structures involved in cognitive and emotional processing and social cognition/mentalization, consistent with clinical and functional data.

Impulsivity, aggression and brain structure in high and low lethality suicide attempters with borderline personality disorder.

PubMed

Soloff, Paul; White, Richard; Diwadkar, Vaibhav A

Impulsivity and aggressiveness are trait dispositions associated with the vulnerability to suicidal behavior across diagnoses. They are associated with structural and functional abnormalities in brain networks involved in regulation of mood, impulse and behavior. They are also core characteristics of borderline personality disorder (BPD), a disorder defined, in part, by recurrent suicidal behavior. We assessed the relationships between personality traits, brain structure and lethality of suicide attempts in 51 BPD attempters using multiple regression analyses on structural MRI data. BPD was diagnosed by the Diagnostic Interview for Borderline Patients-revised, impulsivity by the Barratt Impulsiveness Scale (BIS), aggression by the Brown-Goodwin Lifetime History of Aggression (LHA), and high lethality by a score of 4 or more on the Lethality Rating Scale (LRS). Sixteen High Lethality attempters were compared to 35 Low Lethality attempters, with no significant differences noted in gender, co-morbidity, childhood abuse, BIS or LHA scores. Degree of medical lethality (LRS) was negatively related to gray matter volumes across multiple fronto-temporal-limbic regions. Effects of impulsivity and aggression on gray matter volumes discriminated High from Low Lethality attempters and differed markedly within lethality groups. Lethality of suicide attempts in BPD may be related to the mediation of these personality traits by specific neural networks. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

This study investigated the prevalence and severity of neurological soft signs (NSS), and their relationships with borderline personality (BP) traits in adolescents. Eighty-nine adolescents with BP traits (BP-trait group), and 89 adolescents without traits of any personality disorder (control group), were recruited in China. BP traits were diagnosed by the BPD subscale of the Personality Diagnostic Questionnaire for the DSM-IV (PDQ-4+). The soft sign subscales of the Cambridge Neurological Inventory were administered to all participants. The group differences in prevalence of soft signs and in NSS scores were analyzed, as well as the associations between the NSS scale and borderline personality traits. Five soft signs were significantly more frequent in adolescents with BP traits. A total of 59.6% of adolescents with BP traits exhibited at least 1 NSS, whereas only 34.8% of adolescents without BP traits did (p < 0.01). A total of 42.7% of adolescents in the BP-trait group exhibited at least 2 NSS, while only 16.9% of adolescents without BP traits did (p < 0.001). Moreover, adolescents with BP traits showed more sensory integration, disinhibition, total neurological soft signs, left-side soft signs, and right-side soft signs, than adolescents without BP traits. Sensory integration and disinhibition were positively associated with BP traits. These findings suggest that adolescents with BP traits may have a nonfocal abnormality of the central nervous system.

Many studies have identified various vestibular symptoms and laboratory abnormalities in migraineurs. Although the vestibular tests may be abnormal, the changes may exist without vestibular symptoms. To date, vestibular-evoked myogenic potential (VEMP) has been the easiest and simplest test for measuring vestibular function in clinical practice. Cervical VEMP (cVEMP) represents a vestibulo-collic reflex, whereas ocular VEMP (oVEMP) reflects a vestibulo-ocular pathway. Therefore, we determined whether ocular and rectified cervical VEMPs differed in patients with migraine or tension type headache (TTH) and compared the results to controls with no accompanying vestibular symptoms. The present study included 38 females with migraine without aura, 30 with episodic TTH, and 50 healthy controls without vestibular symptoms. oVEMP and cVEMP using a blood pressure manometer were recorded during a headache-free period. From the VEMP graphs, latency and amplitude parameters were analyzed, especially following EMG rectification in cVEMP. With respect to oVEMP, the migraine group exhibited significantly longer mean latencies of bilateral n1 and left p1 than the other groups (p < 0.05). Amplitudes of n1-p1 were lower than in other groups, but the difference did not reach statistical significance. In regards to cVEMP, p13 and n23 latencies and amplitudes after rectification did not differ significantly among groups. An abnormal interictal oVEMP profile was associated with subclinical vestibular dysfunction in migraineurs, suggesting pathology within the vestibulo-ocular reflex. oVEMP is a more reliable measure than cVEMP to evaluate vestibular function in migraineurs, although results from the two tests in patients with migraine are complementary.

Objectives Our goal was to find the clinical value of cervical vestibular evoked myogenic potential (VEMP) in Ménière's disease (MD) and to evaluate whether the VEMP results can be useful in assessing the stage of MD. Furthermore, we tried to evaluate the clinical effectiveness of VEMP in predicting hearing outcomes. Methods The amplitude, peak latency and interaural amplitude difference (IAD) ratio were obtained using cervical VEMP. The VEMP results of MD were compared with those of normal subjects, and the MD stages were compared with the IAD ratio. Finally, the hearing changes were analyzed according to their VEMP results. Results In clinically definite unilateral MD (n=41), the prevalence of cervical VEMP abnormality in the IAD ratio was 34.1%. When compared with normal subjects (n=33), the VEMP profile of MD patients showed a low amplitude and a similar latency. The mean IAD ratio in MD was 23%, which was significantly different from that of normal subjects (P=0.01). As the stage increased, the IAD ratio significantly increased (P=0.09). After stratification by initial hearing level, stage I and II subjects (hearing threshold, 0-40 dB) with an abnormal IAD ratio showed a decrease in hearing over time compared to those with a normal IAD ratio (P=0.08). Conclusion VEMP parameters have an important clinical role in MD. Especially, the IAD ratio can be used to assess the stage of MD. An abnormal IAD ratio may be used as a predictor of poor hearing outcomes in subjects with early stage MD. PMID:23799160

Objectives HIV-infected women living in resource-constrained nations like Zambia are now accessing antiretroviral therapy and thus may live long enough for HPV-induced cervical cancer to manifest and progress. We evaluated the prevalence and predictors of cervical squamous intraepithelial lesions (SIL) among HIV-infected women in Zambia. Methods We screened 150 consecutive, non-pregnant HIV-infected women accessing HIV/AIDS care services in Lusaka, Zambia. We collected cervical specimens for cytological analysis by liquid-based monolayer cytology (ThinPrep Pap Test®) and HPV typing using the Roche Linear Array® PCR assay. Results The median age of study participants was 36 years (range 23-49 years) and their median CD4+ count was 165/μL (range 7-942). The prevalence of SIL on cytology was 76% (114/150), of which 23.3% (35/150) women had low-grade SIL, 32.6% (49/150) had high-grade SIL, and 20% (30/150) had lesions suspicious for squamous cell carcinoma (SCC). High-risk HPV types were present in 85.3% (128/150) women. On univariate analyses, age of the participant, CD4+ cell count, and presence of any high-risk HPV type were significantly associated with the presence of severely abnormal cytological lesions (i.e., high-grade SIL and lesions suspicious for SCC). Multivariable logistic regression modeling suggested the presence of any high-risk HPV type as an independent predictor of severely abnormal cytology (adjusted OR: 12.4, 95% CI 2.62-58.1, p=0.02). Conclusions The high prevalence of abnormal squamous cytology in our study is one of the highest reported in any population worldwide. Screening of HIV-infected women in resource-constrained settings like Zambia should be implemented to prevent development of HPV-induced SCC. PMID:16875716

To evaluate the Turkey's nationwide HPV DNA screening program on the basis of first 1 million screened women. Women over age 30 were invited for population based screening via HPV DNA and conventional cytology. Samples were collected by family physicians and the evaluations and reports had been performed in the National Central HPV laboratories. The acceptance rate for HPV based cervical cancer screening after first invitation was nearly 36.5%. Since HPV DNA tests have been implemented, cervical cancer screening rates have shown 4-5-fold increase in primary level. Through the evaluation of all, HPV positivity was seen in 3.5%. The commonest HPV genotypes were 16, followed by 51, 31, 52 and 18. Among the 37.515 HPV positive cases, cytological abnormality rate was 19.1%. Among HPV positive cases, 16.962 cases had HPV 16 or 18 or other oncogenic HPV types with abnormal cytology (>ASC-US). These patients were referred to colposcopy. The colposcopy referral rate was 1.6%. Among these, final clinico-pathological data of 3.499 patients were normal in 1.985 patients, CIN1 in 708, CIN2 in 285, CIN3 in 436 and cancer in 85 patients and only pap-smear program could miss 45.9% of ≥CIN3 cases. The results of 1 million women including the evaluation of 13 HPV genotypes with respect to prevalence, geographic distribution and abnormal cytology results shows that HPV DNA can be used in primary level settings to have a high coverage rated screening program and is very effective compared to conventional pap-smear. © 2017 The Authors International Journal of Cancer published by John Wiley & Sons Ltd on behalf of UICC.

Glucose-6-phosphate dehydrogenase (G6PD) deficiency has been revealed to be involved in the efficacy to anti-cancer therapy but the mechanism remains unclear. We aimed to investigate the anti-cancer mechanism of G6PD deficiency. In our study, dehydroepiandrosterone (DHEA) and shRNA technology were used for inhibiting the activity of G6PD of cervical cancer cells. Peak Force QNM Atomic Force Microscopy was used to assess the changes of topography and biomechanical properties of cells and detect the effects on living cells in a natural aqueous environment. Flow cytometry was used to detect the apoptosis and reactive oxygen species (ROS) generation. Scanning electron microscopy was used to observe cell morphology. Moreover, a laser scanning confocal microscope was used to observe the alterations in cytoskeleton to explore the involved mechanism. When G6PD was inhibited by DHEA or RNA interference, the abnormal Young's modulus and increased roughness of cell membrane were observed in HeLa cells, as well as the idioblasts. Simultaneously, G6PD deficiency resulted in decreased HeLa cells migration and proliferation ability but increased ROS generation inducing apoptosis. What's more, the inhibition of G6PD activity caused the disorganization of microfilaments and microtubules of cytoskeletons and cell shrinkage. Our results indicated the anti-cervix cancer mechanism of G6PD deficiency may be involved with the decreased cancer cells migration and proliferation ability as a result of abnormal reorganization of cell cytoskeleton and abnormal biomechanical properties caused by the increased ROS. Suppression of G6PD may be a promising strategy in developing novel therapeutic methods for cervical cancer. Copyright © 2016 Elsevier B.V. All rights reserved.

To compare psychosocial outcomes (follow-up related worries and satisfaction with follow-up related information and support) over 30 months of two alternative management policies for women with low-grade abnormal cervical cytology. Women aged 20-59 years with low-grade cytological abnormalities detected in the National Health Service Cervical Screening Programme were randomised to cytological surveillance or initial colposcopy. A total of 3399 women who completed psychosocial questionnaires at recruitment were invited to complete questionnaires at 12, 18, 24 and 30 months. Linear mixed models were used to investigate differences between arms in the two psychosocial outcomes. Each outcome had a maximum score of 100, and higher scores represented higher psychosocial morbidity. On average, over 30 months, women randomised to colposcopy scored 2.5 points (95%CI -3.6 to -1.3) lower for follow-up related worries than women randomised to cytological surveillance. Women in the colposcopy arm also scored significantly lower for follow-up related satisfaction with information and support (-2.4; -3.3 to -1.4) over 30 months. For both outcomes, the average difference between arms was greatest at 12th- and 18th-month time points. These differences remained when the analysis was stratified by post-school education. Women with low-grade cytology, irrespective of their management, have substantial initial psychosocial morbidity that reduces over time. Implementation of newer screening strategies, which include surveillance, such as primary HPV screening, need to consider the information and support provided to women. © 2016 The Authors.

Human papillomavirus (HPV) infections are causally related to cervical cancer and a range of other diseases, both in adults and in minors. Information on the frequency of genital HPV infections in adolescents is sparse. The aim of this study was to gain insight into the genotype-specific distribution of HPV genotypes in patients younger than 18 years of age. This observational retrospective study included 4807 samples of patients presenting for opportunistic screening in Belgium between June 2006 and January 2012. For statistical analysis, only the first visits of patients were withheld, reducing the sample to 4180. Samples were collected in liquid-based cytology medium and analyzed using a series of genotype-specific real-time PCR reactions. Cytology was read with previous knowledge of HPV infection and scored using the Bethesda classification. The mean age was 16.9 years. Most youngsters had no complaints (88.4%), were using hormonal contraception (79.5%), and clinical examination did not show any abnormalities (96.0%). The overall HPV frequency was 15.7%, with the most frequently found types being HPV16 (16.7%), HPV51 (14.6%), HPV66 (10.4%), HPV31 (9.9%), and HPV39 (9.1%). More than one-third (39.0%) of the infected girls harbored an infection with at least two HPV genotypes. Cytological abnormalities were found in 8.2% of samples. L-SIL (4.2%) was most frequently observed, followed by ASC-US (3.6%), HSIL (0.3%), and ASC-H (0.1%). The severity of lesions worsened with increasing age. Our findings indicate that an aberrant HPV genotype profile can be found in adolescent girls; moreover, this group shows a high rate of cervical abnormalities.

The purpose of this study was to determine the clinical value of a semiquantitative measure of human papillomavirus viral load by the hybrid capture 2 assay for stratification of the risk of histologic cervical intraepithelial neoplasia grade 3 or carcinoma. The Atypical Cells of Unknown Significance and Low-Grade Squamous Intraepithelial Lesions Triage Study was a randomized clinical trial of 5060 women with 2 years of follow-up to evaluate treatment strategies for women with equivocal or mildly abnormal cervical cytologic condition. The usefulness of the continuous hybrid capture 2 output relative light units/positive controls that were above the positive threshold (1.0 relative light units/positive controls), which was a surrogate for human papillomavirus viral load, for distinguishing between hybrid capture 2 positive women who were diagnosed with cervical intraepithelial neoplasia grade 3 or carcinoma during the study from those who were not diagnosed with cervical intraepithelial neoplasia grade 3 or carcinoma was examined with the use of receiver-operator characteristic analyses. Relative light units/positive controls values did not further discriminate between hybrid capture 2 positive women with cervical intraepithelial neoplasia grade 3 or carcinoma from those with less than cervical intraepithelial neoplasia grade 3 or carcinoma. The use of a cervical intraepithelial neoplasia grade 2 or more severe or carcinoma case definition did not alter our findings. Among women with atypical cells of unknown significance or low-grade squamous intraepithelial lesion cervical cytologic findings, the hybrid capture 2 viral load measurement did not improve the detection of 2-year cumulative cases of cervical intraepithelial neoplasia grade 3 or carcinoma significantly.

Background Ossification of the nuchal ligament (ONL) caused by chronic injury to the nuchal ligament (NL) is very common in instability-related cervical disorders. Purpose To determine possible correlations between ONL, sagittal alignment, and segmental stability of the cervical spine. Material and Methods Seventy-three patients with cervical spondylotic myelopathy (CSM) and ONL (ONL group) and 118 patients with CSM only (control group) were recruited. Radiographic data included the characteristics of ONL, sagittal alignment and segmental stability, and ossification of the posterior longitudinal ligament (OPLL). We performed comparisons in terms of radiographic parameters between the ONL and control groups. The correlations between ONL size, cervical sagittal alignment, and segmental stability were analyzed. Multivariate logistic regression was used to identify the independent risk factors of the development of ONL. Results C2-C7 sagittal vertical axis (SVA), T1 slope (T1S), T1S minus cervical lordosis (T1S-CL) on the lateral plain, angular displacement (AD), and horizontal displacement (HD) on the dynamic radiograph increased significantly in the ONL group compared with the control group. The size of ONL significantly correlated with C2-C7 SVA, T1S, AD, and HD. The incidence of ONL was higher in patients with OPLL and segmental instability. Cervical instability, sagittal malalignment, and OPLL were independent predictors of the development of ONL through multivariate analysis. Conclusion Patients with ONL are more likely to have abnormal sagittal alignment and instability of the cervical spine. Thus, increased awareness and appreciation of this often-overlooked radiographic finding is warranted during diagnosis and treatment of instability-related cervical pathologies and injuries.

Background Menkes disease is an X-linked recessive disorder of copper transport caused by mutations in ATP7A, a copper-transporting ATPase. Certain radiologic findings reported in this condition overlap with those caused by child abuse. However, cervical spine defects simulating cervical spine fracture, a known result of nonaccidental pediatric trauma, have not been reported previously in this illness. Objective To assess the frequency of cervical spine anomalies in Menkes disease after discovery of an apparent C2 posterior arch defect in a child participating in a clinical trial. Materials and methods We examined cervical spine radiographs obtained in 35 children with Menkes disease enrolled in a clinical trial at the National Institutes of Health Clinical Center. Results Four of the 35 children with Menkes disease had apparent C2 posterior arch defects consistent with spondylolysis or incomplete/delayed ossification. Conclusion Defects in C2 were found in 11% of infants and young children with Menkes disease. Discovery of cervical spine defects expands the spectrum of radiologic findings associated with this condition. As with other skeletal abnormalities, this feature simulates nonaccidental trauma. In the context of Menkes disease, suspicions of child abuse should be considered cautiously and tempered by these findings to avoid unwarranted accusations. PMID:22825777

Although the etiopathophysiology of internal temporomandibular joint internal disorders (TMJ ID) is still unknown, it has been suggested that head and body posture could be related to its initial onset, development and perpetuation. The purpose of the present study was to observe the relationship between cervical spine X-ray abnormalities and TMJ ID. This investigation evaluated 30 subjects with internal TMJ disorder symptoms (test group) and 20 healthy subjects (control group). Subjects were submitted to clinical and radiographic evaluation. Clinical evaluation comprised anamnesis and stomatognathic system physical examination. Radiographic evaluation comprised analysis of lateral cervical spine X-rays by three physical therapists and tracing on the same images. The test group presented twice as much cervical spine hyperlordosis as the control group (20.7% versus 10.5%), but almost half of rectification prevalence (41.4 versus 79.0%, p = 0.03). After that, the test group was divided into three subgroups according to TMJ dysfunction severity, evaluated by Helkimo's index. These subgroups were not significantly different, but the subgroup with more severe TMD showed a tendency to cervical spine hyperlordosis prevalence. Results showed a tendency for subjects with more severe TMD to exhibit cervical spine hyperlordosis. Nevertheless, studies with a larger number of subjects suffering from severe TMD are encouraged in order to corroborate the present findings.

Cervical cancer burden and prevention strategies: Asia Oceania perspective.

2012-09-01

The Asia Oceania region contributes to more than 50% of cervical cancer cases worldwide. Yet cervical cancer is one of few cancers that can be prevented through comprehensive screening for precancerous lesions, with their subsequent treatment. Screening with cervical cytology, a very old technology, has reduced cervical cancer mortality and incidence when applied in comprehensive programs with high coverage and high quality assurance. However, of those countries within this region that have set up such programs, many have been opportunistic, had poor coverage, or inadequate treatment facilities for lesions found. Consequently, they have not seen large reductions in cancer incidence or mortality. Some have therefore adopted visual inspection by acetic acid (VIA) and Lugol's iodine (VILI) or human papillomavirus (HPV) DNA assays for screening. With two safe, immunogenic and efficacious prophylactic vaccines licensed, the way forward to reduction of cervical cancer to becoming uncommon is within reach. Where governments have supported high coverage public-health vaccination programs, reductions in disease burden with shortest incubation (genital warts, high-grade abnormalities) are already being reported. One of the biggest impediments is the cost of vaccines that are affordable to resource-poor countries. Other challenges include, infrastructure for delivery of vaccines, plus general acceptance of vaccination by the community. ©2012 AACR

Objective Rheumatic heart disease (RHD) remains a major health problem in many low-income and middle-income countries. The use of echocardiographic imaging suggests that subclinical disease is far more widespread than previously appreciated, but little is known as to how these mild forms of RHD progress. We have determined the prevalence of subclinical RHD in a large group of schoolchildren in Aswan, Egypt and have evaluated its subsequent progression. Methods Echocardiographic screening was performed on 3062 randomly selected schoolchildren, aged 5–15 years, in Aswan, Egypt. Follow-up of children with a definite or borderline diagnosis of RHD was carried out 48–60 months later to determine how the valvular abnormalities altered and to evaluate the factors influencing progression. Results Sixty children were initially diagnosed with definite RHD (19.6 per 1000 children) and 35 with borderline disease (11.4 per 1000); most had mitral valve disease. Of the 72 children followed up progression was documented in 14 children (19.4%) and regression in 30 (41.7%) children. Boys had lower rates of progression while older children had lower rates of regression. Functional defects of the valve even in the presence of structural features were associated with lower rates of progression and higher rates of regression than structural changes. Conclusions RHD has a high prevalence in Egypt. Although a high proportion of the abnormalities originally detected persisted at follow-up, both progression and regression of valve lesions were demonstrated. PMID:29344370

Rural-to-urban migration, which has achieved a huge scale during China’s economic reform, is a potential risk factor for the mental health of migrant children. To test this hypothesis, this study assessed the mental health status of rural-to-urban migrant children. Guided by Andersen’s behavioral model, the study explored the risk factors associated with mental health. The study recruited 1182 fifth/sixth-grade children from four private and four public primary schools in Guangzhou in 2014 in a descriptive cross-sectional design. Mental health status was measured by the strengths and difficulties questionnaire. Predisposing characteristics including demographics (e.g., age, gender), social structure (e.g., education, occupation) and health beliefs (health attitude) were recorded. Enabling characteristics including family and community resources and the need for health services were analyzed to explore the risk factors. The results indicate that more rural-to-urban migrant children were classified in the abnormal (21.0%) or borderline (18.8%) categories based on the total difficulties scores, the proportions of which were much higher than those of local children (9.8% abnormal, 13.8% borderline). Factors associated with a greater likelihood of mental health problems included single-parent families, seeking health information actively, family income cannot meet basic needs and poor perceived health status. Compared with the local children, the rural-to-urban migrant children had relatively poor mental health, hence monitoring and supporting mental health for rural-urban migrant children is critical.

The present study examined the association between 9/11-related adolescent behavioral problems on mental health outcomes in early adulthood. Data from enrollees of the World Trade Center Health Registry, who completed at least one adolescent (2006-2007 or 2011-2012) and adult survey (2011-2012 or 2015-2016), were analyzed. Adolescent behavioral difficulties were assessed using the adolescent-reported Strengths and Difficulties Questionnaire (SDQ). Adult mental health outcomes included binge drinking, smoking status history, 9/11-related post-traumatic stress disorder (PTSD), depression, and the self-reported number of physician mental health diagnoses. Multivariable regression was used to estimate associations of SDQ scores with mental health outcomes. Of the 297 enrollees, 16.8% (n = 50) had abnormal/borderline SDQ scores as an adolescent. Binge drinking was not associated with adolescent SDQ scores. Enrollees with abnormal/borderline SDQ scores as an adolescent were more likely to be a consistent smoker (odds ratio (OR): 5.6, 95% confidence interval (CI): 1.2-25.2), have probable PTSD (OR: 3.5, 95% CI: 1.3-9.8), depression (OR: 6.2, 95% CI: 2.7-13.9), and to have two or more self-reported physician-diagnosed mental health conditions as an adult (OR 5.6, 95% CI: 2.0-12.5). The findings of this study underscore the need to intervene early with children exposed to traumatic events so as to avert later adolescent and adult problem behaviors.

Sixteen women with clinically diagnosed uterine masses were studied by magnetic resonance imaging (MRI). Pelvic study was carried out in the coronal, sagittal and axial planes. Uterine leiomyomas were detected in 12 cases, while the remaining cases were one each of uterine sarcoma, invasive molar pregnancy, cervical malignancy with pyometra and haematometra with congenital cervical stenosis. The uterine origin of the masses could be clearly detected in all patients, as well as the nature of the masses, the presence of degenerative or malignant changes and the nature of the intrauterine fluid. MRI characteristic findings of the studied masses are presented and discussed.

Adult polyglucosan body disease (APBD) usually presents with progressive spastic paraparesis, neurogenic bladder, and distal lower limb sensory abnormalities. It is caused by mutations in the glycogen branching enzyme gene (GBE1). We describe a woman with an unusual phenotype manifesting as progressive left brachial more than lumbosacral plexopathies, with central sensory and corticospinal tract involvement. Magnetic resonance imaging of the brain and cervical spine showed abnormal T2 signal within the ventral pons and medulla bilaterally, involving the pyramidal tracts and the medial leminisci. There was also medullary and cervical spine atrophy. On nerve biopsy, large polyglucosan bodies were noted in the endoneurium. The patient was found to be compound heterozygous for 2 novel mutations in GBE1. Peripheral blood leukocyte GBE activity was markedly reduced to 7% of normal, confirming the diagnosis of APBD. In this report we describe a new phenotype of APBD associated with 2 novel mutations. Muscle Nerve 53: 976-981, 2016. © 2016 Wiley Periodicals, Inc.

We aimed to characterize HPV infections and cervical lesions in Western Algeria. A total of 96 cervical samples obtained from women at risk of HPV infection (HIV-1-infected or presenting with a gynecological disease) were analyzed to characterize this infection and search for cytological abnormalities. A total of 60% of women at risk had an HPV infection. The rate of high-risk HPV (HR-HPV) infection among these women was 84.5% and that of intraepithelial lesions was 29.3%. The frequency of HPV infection was significantly higher among HIV-1-infected patients. An association between the presence of HR-HPV and the polygamy of the partner was observed. An association between cytological abnormalities and the use of oral contraceptives was observed among HIV-1-infected women. Given the high frequency of HPV infection in this at risk population, close monitoring and regular gynecological screening are essential. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Not all cases of nyctalopia are benign: Unusual and serendipitous presentation of Arnold–Chiari Type 1 malformation at a Pediatric Tertiary Care Center

Patra, Kailash Chandra; Kirtane, Abhijeet Prakash

2016-01-01

The Arnold–Chiari Type 1 malformation (CM1) is a rare congenital abnormality characterized by ectopia or caudal herniation of the cerebellar tonsils through the foramen magnum into the cervical spine, resulting in crowding at the craniocervical junction. It seldom presents in childhood with symptoms and a normal neurological examination. More typically, CM1 presents in young adult women with neurological symptoms including a headache, cervical pain, cranial nerve palsies, neurosensory deficit, and ataxia. Ocular manifestations associated with Chiari I include third and sixth cranial nerve paresis and convergence/divergence abnormalities. Papilledema is a rare manifestation of Chiari I with a clinical presentation often similar to that of idiopathic intracranial hypertension. To underscore this noteworthy complication, the authors report a case of an 8-year-old boy who presented with nyctalopia and suboccipital headaches, but was diagnosed serendipitously as a case of papilledema due to Chiari I malformation.

The Arnold-Chiari Type 1 malformation (CM1) is a rare congenital abnormality characterized by ectopia or caudal herniation of the cerebellar tonsils through the foramen magnum into the cervical spine, resulting in crowding at the craniocervical junction. It seldom presents in childhood with symptoms and a normal neurological examination. More typically, CM1 presents in young adult women with neurological symptoms including a headache, cervical pain, cranial nerve palsies, neurosensory deficit, and ataxia. Ocular manifestations associated with Chiari I include third and sixth cranial nerve paresis and convergence/divergence abnormalities. Papilledema is a rare manifestation of Chiari I with a clinical presentation often similar to that of idiopathic intracranial hypertension. To underscore this noteworthy complication, the authors report a case of an 8-year-old boy who presented with nyctalopia and suboccipital headaches, but was diagnosed serendipitously as a case of papilledema due to Chiari I malformation.

Spasmodic torticollis: the dental connection.

Sims, Anthony B; Stack, Brendan C; Demerjian, G Gary

Spasmodic torticollis or cervical dystonia (CD) is the most common form of focal dystonia and is characterized by sustained abnormal muscle contractions in the head and neck area resulting in abnormal positioning or posturing of the head. The dystonic muscle spasms associated with spasmodic torticollis may affect any combination of neck muscles. Three cases are reported of spasmodic torticollis that were treated by a dental appliance with individual varying occlusal heights to open the maxillomandibular vertical dimension. Upon increasing the vertical dimension of occlusion, there was a slowing and/or discontinuance of the symptoms of cervical dystonia. The proposed hypothesis for this reversal is that there may be neuritis of the auriculotemporal branch of the trigeminal nerve, which has direct input into the reticular formation (RF), and it may activate the cells of the pontine region of the RF known for the control and deviation of head posture. There is growing clinical evidence that temporomandibular joint (TMJ) dysfunction may be a factor in this neurological and painful disorder when it coexists.

Colonization with Trichomonas vaginalis is a possible cause of poor pregnancy outcome. To facilitate the diagnosis of this condition during pregnancy, we conducted a prospective, multicenter study of 13,816 gravid women who were between 23rd and 26th week of gestation. Findings significantly associated with T. vaginalis colonization included a yellow, green, or bloody discharge from the vagina or cervix; abnormal odor after KOH was added to a vaginal specimen; a vaginal pH of > 5.0; and cervical friability. The amount of vaginal discharge and abnormal consistency of the discharge were also associated with T. vaginalis colonization. These findings (except for cervical bleeding and odor after the addition of KOH to a vaginal specimen, which may be influenced by the presence of other flora) are consistent with those reported elsewhere. The clinical usefulness of these features is minimal, and it is more significant that other microorganisms are makers for trichomoniasis; therefore, controlling for other flora is important in the investigation of T. vaginalis colonization.

Women who delay or do not attend Papanicolaou (Pap) screening are at increased risk for cervical cancer. Trials in countries with organized screening programs have demonstrated that mailing high-risk (hr) human papillomavirus (HPV) self-sampling kits to under-screened women increases participation, but U.S. data are lacking. HOME is a pragmatic randomized controlled trial set within a U.S. integrated healthcare delivery system to compare two programmatic approaches for increasing cervical cancer screening uptake and effectiveness in under-screened women (≥3.4years since last Pap) aged 30-64years: 1) usual care (annual patient reminders and ad hoc outreach by clinics) and 2) usual care plus mailed hrHPV self-screening kits. Over 2.5years, eligible women were identified through electronic medical record (EMR) data and randomized 1:1 to the intervention or control arm. Women in the intervention arm were mailed kits with pre-paid envelopes to return samples to the central clinical laboratory for hrHPV testing. Results were documented in the EMR to notify women's primary care providers of appropriate follow-up. Primary outcomes are detection and treatment of cervical neoplasia. Secondary outcomes are cervical cancer screening uptake, abnormal screening results, and women's experiences and attitudes towards hrHPV self-sampling and follow-up of hrHPV-positive results (measured through surveys and interviews). The trial was designed to evaluate whether a programmatic strategy incorporating hrHPV self-sampling is effective in promoting adherence to the complete screening process (including follow-up of abnormal screening results and treatment). The objective of this report is to describe the rationale and design of this pragmatic trial. Copyright © 2017 Elsevier Inc. All rights reserved.

In order to evaluate the newly implemented gender-neutral HPV vaccination program, knowledge on the pre-vaccine prevalence of HPV infection is of paramount importance. Data on HPV infection among the women with no known previous cytological abnormalities are inexistent in Austria. This study presents data on the prevalence and distribution of HPV genotypes among women with no known cytological abnormalities in west Austria. Women between 18 and 65 years of age attending annual cervical cancer screening examinations were included in the study. Data on socio-demographic and reproductive factors were collected using structured questionnaires. Corresponding cervical swab samples were tested for the presence of HPV DNA and were genotyped. Questionnaire data and HPV status were linked with the corresponding cytological findings. A total of 542 women were included in the study. The mean age of the study participants was 35.9 (SD = 11.5). The prevalence of HPV infection was 20.5 %. HPV 16 (6.5 %), HPV 33 (3.3 %) and HPV 31 (3.0 %) were the dominant genotypes detected. Multivariate analysis showed that women younger than 30 years of age, smokers, women with a higher number of lifetime sexual partners and those living in the eastern districts of the study region were at significantly higher risk of HPV infection. With this study we present the first data on the prevalence of cervical HPV genotypes among a screening population in Austria. The results not only fill the missing information on HPV infection in this group of women in the country, they also provide baseline data for a future evaluation of the impact of the Austrian gender-neutral HPV immunization program. Moreover, our finding of higher HPV prevalence in the eastern compared to the western district of the study region may - at least partly - explain the east-west gradient in the standardized incidence rate of cervical cancer in the region.

Koilocytosis (cavitation of the cytoplasm due to active HPV infection) can be detected in the screening process for cervical carcinoma. To report the practice of detection of koilocytosis and (pre)neoplasia in population screening and to exploit the collected data to propose an explanation for the relationship between HPV infection and nuclear precancerous changes. Centrally collected and stored (SBBW, Leiden, the Netherlands) data from all smears of six regional pathology laboratories (1995-2002), coded according to KOPAC (the national cervical smear coding system; S1: normal thru S9: invasive carcinoma) were accessed. Prevalences per 100,000 smears were calculated for koilocytosis and for squamous abnormalities after stratification for country of origin of screenees. The relative risk (RR) for the ethnic (age) groups was computed by dividing the prevalence of the relevant ethnic (age) group by the prevalence of all women. Surinamese women featured the highest prevalence of koilocytosis and of all squamous abnormalities. Moroccan women the lowest. The RR for koilocytosis was highest at 30 years (1.84) and lowest at 60 (0.26). RR dependence on age of S5-S9 lesions was similar. Compared to nonkoilocytotic smears, koilocytosis was 104 times more frequent in the 1,500 S4 smears, 36x more frequent in the 6,700 S2-S3 smears, and 24x more frequent in the 1,740 S5-S9 smears. In all three categories this difference is statistically significant. High prevalences for both koilocytosis and for preneoplasia were detected in Surinamese immigrants, however, it still does not exclude HPV infection as a confounder linked to sexual lifestyle. The presence of koilocytosis in cervical smears may serve to identify patients with an increased risk for cervical cancer and perhaps warrant more intensive surveillance than what is provided through five-yearly screening.

Technologic advances for evaluation of cervical cytology: is newer better?

Among those women who have cervical cancer and have been screened, 14% to 33% of the cases represent failure to detect abnormalities that existed at the time of screening. New technologies intended to improve detection of cytologic abnormalities include liquid-based, thin-layer cytology (ThinPrep, AutoCyte), computerized rescreening (PAPNET), and algorithm-based computer rescreening (AutoPap). This report combines evidence reviews conducted for the U.S. Preventive Services Task Force and the Agency for Healthcare Research and Quality, in which we systematically identified articles on cervical neoplasia, cervical dysplasia, and screening published between January 1966 and March 2001. We note the challenges for improving screening methods, providing an overview of methods for collecting and evaluating cytologic samples, and examining the evidence about the diagnostic performance of new technologies for detecting cervical lesions. Using standard criteria for evaluation of the diagnostic tests, we determined that knowledge about the sensitivity, specificity, and predictive values of new technologies is meager. Only one study of liquid-based cytology used a reference standard of colposcopy, with histology as indicated, to assess participants with normal screening results. Lack of an adequate reference standard is the overwhelming reason that test characteristics cannot be properly assessed or compared. Most publications compare results of screening using the new technology with expert panel review of the cytologic specimen. In that case, the tests are not independent measures and do nothing to relate the screening test findings to the true status of the cervix, making determination of false-negatives, and thus sensitivity, specificity, and negative predictive value, impossible. We did not identify any literature about health outcomes or cost effectiveness of using these tools in a system of screening. For the purposes of guiding decision making about choice of screening tools, the current evidence is inadequate to gauge whether new technologies are "better" than conventional cytology..

Solid-organ transplant recipients are at increased risk of developing cancer including cervical cancer compared with woman in the general population, mostly due to long-term immunosuppressive therapy. The Papanicolaou smear remains the primary method of screening cervical pathology including preinvasive and invasive lesions. The objective of this study was to evaluate Pap smear findings in solid-organ transplant recipients, determine the prevalence of abnormal smears, and compare these patients with the general population. We retrospectively examined 111 women patients who received liver or kidney transplant between January 1990 to December 2012 at Başkent University Ankara Hospital. Pap smear findings were compared with normal control patients matched for same age and technical procedure of cervical cytology. To selection of control patients, propensity score matching program was performed. All Pap smears were re-examined according to Bethesda 2001 criteria. In 111 transplant patients, 2 patients (1.8%) had atypical squamous cells of undetermined significance, 8 patients (7.2%) had low-grade squamous intraepithelial lesion, 15 patients (13.5%) had Candida infection, 2 patients (1.8%) had Trichomonas vaginalis, 1 patient (0.9%) had herpes simplex infection, 13 patients (11.7%) had bacterial vaginosis, 15 patients (13.5%) had reactive changes due to inflammation, and 18 patients (16.2%) had atrophy. When we compared our results with the control group, there were statistically significant differences (P ≤ .05) between the 2 groups in epithelial cell abnormalities (low-grade squamous intraepithelial lesion), Candida infection, bacterial vaginosis, and atrophy. Pap smear screening potentially may help recognize cervical preinvasive and invasive lesions. The risk of developing cervical intraepithelial neoplasia is greater in transplant recipients because of immunosuppressive therapy. The incidence of low-grade squamous intraepithelial lesion was significantly greater in transplant recipients than the general population. Intensive follow-up with Pap smear in transplant recipients is important in the early detection of these lesions.

This paper describes the study design and baseline characteristics of the study population, including the first 30 829 women who enrolled in the Forwarding Research for Improved Detection and Access for Cervical Cancer Screening and Triage (FRIDA Study). This is a large population based study that is evaluating the performance and cost-effectiveness of different triage strategies for high-risk HPV (hrHPV) positive women in Mexico. The target population is more than 100 000 women aged 30 to 64 years who attend the Cervical Cancer Screening Program in 100 health centers in the state of Tlaxcala, Mexico. Since August 2013, all women in the region have been invited to enroll in the study. The study participants are evaluated to determine hrHPV infection using the Cobas 4800 HPV test. The HPV-16/18 genotyping and cytology triage strategies are performed as reflex tests in all hrHPV-positive participants. Women with a positive HPV-16/18 test and/or abnormal cytology (atypical squamous cells of undetermined significance or worse, ASCUS+) are referred for colposcopy evaluation, where a minimum of four biopsies and an endocervical sample are systematically collected. Histologic confirmation is performed by a standardized panel of pathologists. Among the 30 829 women who have been screened, the overall prevalence of hrHPV is 11.0%. The overall prevalence of HPV16 and HPV18 are 1.5% and 0.7%, respectively. Cytological abnormalities (ASCUS+) were detected in 11.8% of the hrHPV-positive women. A total of 27.0% (920/3,401) of the hrHPV-positive women were referred to colposcopy because of a positive HPV16/18 test and/or abnormal reflex cytology, (31.6% had only ASCUS+, 53.6% were HPV16/18 positive with a normal cytology result, and 9.5% were positive to both triage tests). The results of this study will help policy makers and health service providers establish the best practices for triage in cervical cancer screening in Mexico and other countries.

Objective Costs associated with HPV-related diseases such as cervical dysplasia, cervical cancer, and genital warts have not been evaluated in Sweden. These costs must be estimated in order to determine the potential savings if these diseases were eradicated and to assess the combined cost-effectiveness of HPV vaccination and cervical cancer screening. The present study aimed to estimate prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts from a societal perspective in Sweden in 2009, 1 year before the quadrivalent HPV vaccination program was implemented. Methods and Materials Data from the Swedish cervical cancer screening program was used to calculate the costs associated with prevention (cytological cervical cancer screening), management (colposcopy and biopsy following inadequate/abnormal cytological results), and treatment of CIN. Swedish official statistics were used to estimate treatment costs associated with cervical cancer. Published epidemiological data were used to estimate the number of incident, recurrent, and persistent cases of genital warts; a clinical expert panel assessed management and treatment procedures. Estimated visits, procedures, and use of medications were used to calculate the annual cost associated with genital warts. Results From a societal perspective, total estimated costs associated with cervical cancer and genital warts in 2009 were €106.6 million, of which €81.4 million (76%) were direct medical costs. Costs associated with prevention, management, and treatment of CIN were €74 million; screening and management costs for women with normal and inadequate cytology alone accounted for 76% of this sum. The treatment costs associated with incident and prevalent cervical cancer and palliative care were €23 million. Estimated costs for incident, recurrent and persistent cases of genital warts were €9.8 million. Conclusion Prevention, management, and treatment costs associated with cervical dysplasia, cervical cancer, and genital warts are substantial. Defining these costs is important for future cost-effectiveness analyses of the quadrivalent HPV vaccination program in Sweden. PMID:26398189

Epithelioid trophoblastic tumor is a recently described, rare and distinctive type of gestational trophoblastic tumor. We report the case of a 31-year old patient who had a full-term pregnancy 18 months before presentation. She had a right axillary lymph node metastasis and was referred for FDG-PET/CT scan for evaluation of distant metastasis and to detect primary malignancy. The axillary lymph node biopsy revealed metastatic breast carcinoma. FDG-PET/CT revealed increased uptake of right axillary lymph node, soft tissue density lesion with a diameter of 24 mm on left cervical region with increased FDG uptake, increased uptake on cervical region and left inguinal lymph node with increased uptake. Pelvic MRI imaging and ultrasonography were negative for malignancy in cervical region. Biopsy of the lesion was consistent with epithelioid trophoblastic tumor in cervical region. Gestational trophoblastic tumor was not suspected because she had no signs such as abnormal vaginal bleeding. FDG-PET/CT demonstrated the primary lesion in cervical region. We report a rare case of primary epithelioid trophoblastic tumor detected only with FDG-PET/CT scan which synchronized with breast carcinoma. Copyright © 2010 Elsevier España, S.L. and SEMNIM.

Human papillomavirus (HPV) is strongly implicated in the pathogenesis of cervical neoplasia. The ability of a commercially available kit (Virapap/Viratype) to detect evidence of HPV is compared with cervical cytology, colposcopy, and directed biopsies. During a period of 16 months, cervical samples from 241 consecutive new patients referred for a colposcopy examination were obtained for HPV-DNA hybridization typing according to the kit instructions. Samples were sent to a reference laboratory for testing. The results were compared with results of the colposcopy examination, cervical cytology, and directed cervical biopsy samples processed and evaluated by our hospital laboratory. HPV DNA was detected in 27 of 107 patients who had abnormal colposcopy findings for a sensitivity of 25 +/- 7.5 percent at the 90 percent confidence interval. One of 134 patients with normal findings was positive for a specificity of 99 +/- 5 percent at the 95 percent confidence interval. Based on a 75 percent probability of HPV in the population, the positive predictive value was 99 percent and the negative predictive value 30 percent. With the low negative predictive value and sensitivity, HPV-DNA testing by this commercial kit is not an adequate tool for screening HPV in this population.

Cervical cancer remains a major cause of morbidity and mortality among women, especially in the developing world. Increased synthesis of proteins, lipids and nucleic acids is a pre-condition for the rapid proliferation of cancer cells. We show that scanning near-field optical microscopy, in combination with an infrared free electron laser (SNOM-IR-FEL), is able to distinguish between normal and squamous low-grade and high-grade dyskaryosis, and between normal and mixed squamous/glandular pre-invasive and adenocarcinoma cervical lesions, at designated wavelengths associated with DNA, Amide I/II and lipids. These findings evidence the promise of the SNOM-IR-FEL technique in obtaining chemical information relevant to the detection of cervical cell abnormalities and cancer diagnosis at spatial resolutions below the diffraction limit (≥0.2 μm). We compare these results with analyses following attenuated total reflection Fourier-transform infrared (ATR-FTIR) spectroscopy; although this latter approach has been demonstrated to detect underlying cervical atypia missed by conventional cytology, it is limited by a spatial resolution of ~3 μm to 30 μm due to the optical diffraction limit.

Vertebral hyperostosis typically predominates at the thoracic spine and causes only minor symptoms. Involvement of the cervical spine may cause dysphagia due to pressure on the esophagus. We report three cases of dysphagia revealing cervical hyperostosis. The patients were 3 men aged 54-73 years. Dysphagia was moderate in 2 patients and severe in 1 patient who had lost 4 kg over 6 months. Stiffness of the neck with mild pain was present. One patient reported a neck injury in childhood and another had a brother and father with similar symptoms. Radiographs showed exuberant anterior cervical hyperostosis. Two patients also had hyperostotic changes at the thoracic spine and pelvis. The skin and neurological evaluation were normal. Findings were normal from standard blood tests (C-reactive protein, calcium, and vitamin D). Tests were negative for the HLA-B27 antigen in all 3 patients. Serum vitamin A levels were high, ranging from 894 to 1123 microg/L (normal, 489-720). None of the patients reported taking retinoids or having unusual eating habits. Dysphagia can result from anterior cervical hyperostosis. A role for hypervitaminosis A in the genesis of hyperostosis has long been suspected. In our patients, the absence of vitamin A supplementation suggests an abnormality in vitamin A metabolism.

The use of laser therapy in CIN, is a practical method that has revolutionized the treatment of a very common pathology, that is the cervical neoplasia in its early stages. 86 patients with different stages of cervical intraepithelial neoplasia, were studied. Patients in groups I (45 patients) y II (28 patients), were submitted to a vaporization crater of the whole transformation zone because of having the cervical canal free of lesion. In group III (13 patients), a cylinder of the cervix was done to perform histological study, whether the cervical canal was compromised or not. The cytology control results for group I were excellent; from (45 patients) who came to 3-month check-up 79.1% of the whole presented negative II. For group II (28 patients), in first pap smear two patients (7.1%) had CIN, the rest of smears were reported 66% negative II, and in the 30.6% negative I. For the group III 14.2% (5 patients) of the whole had abnormal results, the rest of the smears 73.5% of the results reported negative II. The incidence of failure for this procedure is similar to that of hysterectomy with the same therapeutic goal .

Cervical radiculopathy represents aberrant mechanical hypersensitivity. Primary sensory neuron’s ability to sense mechanical force forms mechanotransduction. However, whether this property undergoes activity-dependent plastic changes and underlies mechanical hypersensitivity associated with cervical radiculopathic pain (CRP) is not clear. Here we show a new CRP model producing stable mechanical compression of dorsal root ganglion (DRG), which induces dramatic behavioral mechanical hypersensitivity. Amongst nociceptive DRG neurons, a mechanically sensitive neuron, isolectin B4 negative Aδ-type (IB4− Aδ) DRG neuron displays spontaneous activity with hyperexcitability after chronic compression of cervical DRGs. Focal mechanical stimulation on somata of IB4- Aδ neuron induces abnormal hypersensitivity. Upregulated HCN1 and HCN3 channels and increased Ih current on this subset of primary nociceptors underlies the spontaneous activity together with neuronal mechanical hypersensitivity, which further contributes to the behavioral mechanical hypersensitivity associated with CRP. This study sheds new light on the functional plasticity of a specific subset of nociceptive DRG neurons to mechanical stimulation and reveals a novel mechanism that could underlie the mechanical hypersensitivity associated with cervical radiculopathy.

The aim of this study is to gain knowledge about women's perceptions of illness based on their abnormal PAP smears, following screening for cervical cancer. The study uses a phenomenological, hermeneutic approach inspired by Ricoeur's theory of interpretation. Twelve women, aged between 23 and 59 years, were consecutively selected and then followed by participant observation during their examinations and treatment in hospital. They were interviewed on entering the study, a week following their surgery, and 6 months later. The material collected was analysed through a dialectic process consisting of a face-value review of participant experiences (naive reading), structural analysis and, critical interpretation of what it means to be potentially ill. The women were unprepared to find that their screening results showed abnormal cells, indicative of incipient genital cancer. They were frustrated by the results as they had not experienced any symptoms and felt well, despite being diagnosed with a potential disease. Being diagnosed with abnormal cells caused the participants to feel anxious. Their anxiety had subsided 6 months after the cells had been removed. For those who did not require treatment, anxiety flared up with recurrent check-ups. The bio-medical differentiation between pre-stage and actual cancer provided no comfort to the participants, who continued to see themselves as having early stage cancer.

The aim of this study was to compare the performance of multimodal hyperspectral spectroscopy (MHS), which combines fluorescence and reflectance spectroscopy, with that of conventional laboratory-based screening tests, such as the Papanicolaou (Pap) smear test and human papilloma virus (HPV) DNA test, for detecting precancerous lesions of the cervix. The study utilized a cross-sectional design, and the kappa test was used in the analytical assessment. MHS scans were obtained from a sample of 70 consecutive patients, followed by sample collection for Pap and HPV DNA analysis and colposcopy referral, if indicated. Of the 70 patients evaluated, the results of cervical spectroscopy were normal in 38 (54.3%) patients, and they were abnormal in 32 (45.7%) patients. Based on the cytology results, 45 (64.3%) samples were normal, and 25 (35.7%) samples were abnormal. According to the results of the HPV DNA test, 47 (67.14%) samples were normal, and 17 (24.28%) samples were abnormal. Based on the results of the kappa test, the agreement between MHS and cytology was 0.793 (p < 0.001). The agreement between MHS and the HPV DNA test was 0.195 (p = 0.086), and the agreement between MHS and colposcopy was 0.479 (p < 0.001).

Cervical cancer is the second commonest cancer in women worldwide and the commonest cancer among women in Uganda. Annual cervical screening is recommended for women living with HIV for early detection of abnormal cervical changes, however uptake remains grossly limited. This study assessed factors associated with cervical screening uptake among HIV infected women at Mildmay Uganda where cervical screening using Visual inspection with acetic acid and iodine (VIA and VILI) was integrated into HIV care since July 2009. Eighteen (18) in-depth interviews with HIV infected women and 6 key informant interviews with health care providers were conducted in April 2013 to assess client, health care provider and facility-related factors that affect cervical screening uptake. In-depth interview respondents included six HIV infected women in each of the following categories; women who had never screened, those who had screened once and missed follow-up annual screening, and those who had fully adhered to the annual screening schedule. Data was analyzed using content analysis method. Motivations for cervical cancer screening included the need for comprehensive assessment, diagnosis, and management of all ailments to ensure good health, fear of consequences of cervical cancer, suspicion of being at risk and the desire to maintain a good relationship with health care workers. The following factors negatively impacted on uptake of cervical screening: Myths and misconceptions such as the belief that a woman's ovaries and uterus could be removed during screening, fear of pain associated with cervical screening, fear of undressing and the need for women to preserve their privacy, low perceived cervical cancer risk, shortage of health workers to routinely provide cervical cancer education and screening, and competing priorities for both provider and patient time. Major barriers to repeat screening included limited knowledge and appreciation of the need for repeat screening, and lack of reminders. These findings highlight the need for client-centered counseling and support to overcome fears and misconceptions, and to innovatively address the human resource barriers to uptake of cervical cancer screening among HIV infected women.

Abstract A primary cause of morbidity and mortality following cervical spinal cord injury (SCI) is respiratory compromise, regardless of the level of trauma. In particular, SCI at mid-cervical regions targets degeneration of both descending bulbospinal respiratory axons and cell bodies of phrenic motor neurons, resulting in deficits in the function of the diaphragm, the primary muscle of inspiration. Contusion-type trauma to the cervical spinal cord is one of the most common forms of human SCI; however, few studies have evaluated mid-cervical contusion in animal models or characterized consequent histopathological and functional effects of degeneration of phrenic motor neuron–diaphragm circuitry. We have generated a mouse model of cervical contusion SCI that unilaterally targets both C4 and C5 levels, the location of the phrenic motor neuron pool, and have examined histological and functional outcomes for up to 6 weeks post-injury. We report that phrenic motor neuron loss in cervical spinal cord, phrenic nerve axonal degeneration, and denervation at diaphragm neuromuscular junctions (NMJ) resulted in compromised ipsilateral diaphragm function, as demonstrated by persistent reduction in diaphragm compound muscle action potential amplitudes following phrenic nerve stimulation and abnormalities in spontaneous diaphragm electromyography (EMG) recordings. This injury paradigm is reproducible, does not require ventilatory assistance, and provides proof-of-principle that generation of unilateral cervical contusion is a feasible strategy for modeling diaphragmatic/respiratory deficits in mice. This study and its accompanying analyses pave the way for using transgenic mouse technology to explore the function of specific genes in the pathophysiology of phrenic motor neuron degeneration and respiratory dysfunction following cervical SCI.

The Papanicolaou test (or Pap test) has long been used as a screening tool to detect cervical precancerous/cancerous lesions. However, studies on the use of this test to predict both the presence and change in size of genital warts are limited. We examined whether cervical Papanicolaou test results are associated with the size of the largest anal wart over time in HIV-infected women in an on-going cohort study in the US. A sample of 976 HIV-infected women included in a public dataset obtained from the Women’s Interagency HIV Study (WIHS) was selected for analysis. A linear mixed model was performed to determine the relationship between the size of anal warts and cervical Pap test results. About 32% of participants had abnormal cervical Pap test results at baseline. In the adjusted model, a woman with a result of Atypia Squamous Cell Undetermined Significance/Low-grade Squamous Intraepithelial Lesion (ASCUS/LSIL) had an anal wart, on average, 12.81 mm2 larger than a woman with normal cervical cytology. The growth rate of the largest anal wart after each visit in a woman with ASCUS/LSIL was 1.56 mm2 slower than that of a woman with normal cervical results. However, they were not significant (P = 0.54 and P = 0.82, respectively). This is the first study to examine the relationship between cervical Pap test results and anal wart development in HIV-infected women. Even though no association between the size of anal wart and cervical Pap test results was found, a screening program using anal cytology testing in HIV-infected women should be considered. Further studies in cost-effectiveness and efficacy of an anal cytology test screening program are warranted. PMID:24312348

Thoracic injuries are a major cause of death associated with blunt trauma in children. Screening for injury with chest x-ray study, compared with chest computed tomography (CT) scan, has been controversial, weighing the benefits of specificity with the detriment of radiation exposure. To identify predictors of thoracic injury in children presenting as trauma activations to a Level I trauma center after blunt torso trauma, and to compare these predictors with those previously reported in the literature. We performed a retrospective chart review of pediatric patients (<18 years of age) who presented to the Emergency Department of a Level I trauma center between June 2010 and June 2013 as a trauma activation after sustaining a blunt torso trauma and who received diagnostic imaging of the chest as part of their initial evaluation. Data analysis was performed on 166 patients. There were 33 patients (20%) with 45 abnormalities detected on diagnostic imaging of the chest, with the most common abnormalities being lung contusion (36%), pneumothorax (22%), and rib fracture (13%). Statistically significant predictors of abnormal diagnostic imaging of the chest included Glasgow Coma Scale score (GCS) < 15 (27% with abnormality vs. 13% without abnormality), hypoxia (22% vs. 5%), syncope/loss of consciousness (55% vs. 35%), cervical spine tenderness (12% vs. 3%), thoraco-lumbar-sacral spine tenderness (41% vs. 17%), and abdominal/pelvic tenderness (12% vs. 3%). Based on our data, predictors of thoracic injury in children after blunt torso trauma include GCS < 15, hypoxia, syncope/dizziness, cervical spine tenderness, thoraco-lumbar-sacral spine tenderness, and abdominal/pelvic tenderness.

This study aimed to evaluate the incidence of anal dysplasia in women at high risk of developing those lesions and to assess the relationships between positive anal cytology and different risk factors. We performed an observational cross-sectional study involving a patient survey and chart review. The study was conducted at the cervical pathology unit at the Hospital Universitario 12 de Octubre, Madrid, Spain, from 2011 to 2015. Patients were 215 women aged 18 to 65 years old with risk factors for anal dysplasia, for whom anal evaluation was indicated. Anal cytology was performed in all patients. High-resolution anoscopy and anal biopsy were used to investigate abnormalities. All patients completed a survey regarding sexual practices. The patients' demographic and clinical data were collected by using a retrospective chart review. The main outcome measure was the incidence of anal dysplasia in this population. Of the 215 patients, 45 (21.0%) presented with cytological abnormalities (atypical squamous cells of undetermined significance, 13.5%; low-grade squamous intraepithelial lesion, 5.6%; high-grade squamous intraepithelial lesion, 1.9%). Anoscopy was performed in 31 patients (14.4%) and 2 patients (0.9%) had abnormal findings. One case (0.5%) of low-grade anal intraepithelial neoplasia was identified. Only immunosuppression (p = .01) and smoking status (p = .02) were significantly correlated with positive anal cytology results. Limitations of the study include the small single-center sample, a lack of controls, the retrospective design, potential survey response biases, and the nonstandardized survey. The incidence of abnormal cytological findings was 21.0%, whereas low-grade anal intraepithelial was confirmed in 0.5% of the patients. There is a higher incidence of cytological abnormalities among immunosuppressed women and smokers.

From Cancer Screening to Treatment: Service Delivery and Referral in the National Breast and Cervical Cancer Early Detection Program

The National Breast and Cervical Cancer Early Detection Program (NBCCEDP) provides breast and cervical cancer screening and diagnostic services to low-income and underserved women through a network of providers and health care organizations. Although the program serves women 40-64 years old for breast cancer screening and 21-64 years old for cervical cancer screening, the priority populations are women 50-64 years old for breast cancer and women who have never or rarely been screened for cervical cancer. From 1991 through 2011, the NBCCEDP provided screening and diagnostic services to more than 4.3 million women, diagnosing 54,276 breast cancers, 2554 cervical cancers, and 123,563 precancerous cervical lesions. A critical component of providing screening services is to ensure that all women with abnormal screening results receive appropriate and timely diagnostic evaluations. Case management is provided to assist women with overcoming barriers that would delay or prevent follow-up care. Women diagnosed with cancer receive treatment through the states' Breast and Cervical Cancer Treatment Programs (a special waiver for Medicaid) if they are eligible. The NBCCEDP has performance measures that serve as benchmarks to monitor the completeness and timeliness of care. More than 90% of the women receive complete diagnostic care and initiate treatment less than 30 days from the time of their diagnosis. Provision of effective screening and diagnostic services depends on effective program management, networks of providers throughout the community, and the use of evidence-based knowledge, procedures, and technologies.

Incarcerated women's HPV awareness, beliefs, and experiences.

Pankey, Tyson; Ramaswamy, Megha

2015-01-01

The purpose of this paper is to explore incarcerated women's awareness, beliefs, and experiences with human papillomavirus (HPV) infection and vaccination. Researchers conducted focus groups with 45 incarcerated women in an urban Midwestern US jail to assess how women talked about their Papanicolaou (Pap) test screening and abnormal Pap test follow-up experiences. Some focus group questions specifically assessed individual awareness, beliefs, and experiences with HPV infection and vaccination. Based on these data, the authors described participants' awareness of HPV, as well as used open coding to ultimately extract themes related to beliefs and experiences with HPV infection and vaccine. While all 45 participants reported experiencing an abnormal Pap test event within the last five years, only two-thirds of participants (n=30) reported having heard of the HPV infection. Several themes emerged from the analysis of the data: the women's beliefs about cause and severity of HPV; frustration with age requirements of the vaccine; varied experiences with vaccinations for themselves and their children; the impact of media exposure on knowledge; and desire for more HPV infection and vaccine information. Incarcerated women's awareness and limited experiences with HPV infection and vaccination may be a barrier to adequate screening and cervical cancer prevention. This study has implications for the development of cervical health education for this high-risk group of women, who are four to five times as likely to have cervical cancer as non-incarcerated women.

The impact of human papillomavirus (HPV) vaccination on cervical screening, colposcopy, and treatment is incompletely understood. In 2004-2005, investigators in the Costa Rica Vaccine Trial randomized 7,466 women aged 18-25 years, 1:1, to receive HPV vaccination or hepatitis A vaccination. The worst-ever cytology diagnosis and the 4-year cumulative proportions of colposcopy referral and treatment by vaccination arm were compared for 2 cohorts. The total vaccinated cohort included 6,844 women who provided cervical samples. The naive cohort included 2,284 women with no evidence of previous HPV exposure. In the total vaccinated cohort, HPV-vaccinated women had a significant (P = 0.01) reduction in cytological abnormalities: 12.4% for high-grade lesions and 5.9% for minor lesions. Colposcopy referral was reduced by 7.9% (P = 0.03) and treatment by 11.3% (P = 0.24). Greater relative reductions in abnormal cytology (P < 0.001) were observed for HPV-vaccinated women in the naive cohort: 49.2% for high-grade lesions and 18.1% for minor lesions. Colposcopy referral and treatment were reduced by 21.3% (P = 0.01) and 45.6% (P = 0.08), respectively, in the naive cohort. The overall impact on health services will be modest in the first years after vaccine introduction among young adult women, even in regions with high coverage.

The objective of this study was to establish the relationship between Candida vaginalis and (pre)neoplasia and the prevalence of Candida and (pre)neoplasia related to age and ethnicity. Data were collected from 445,671 asymptomatic women invited for mass screening between 1995 and 2002 and coded according to the Dutch cervical smear coding system (KOPAC) with six grades for (pre)neoplastic changes. Prevalence and relative risks (RRs) were established for Candida and squamous abnormalities in Dutch women and four groups of immigrants. The prevalence of Candida is significantly higher in the cohort of 30-year-old women and lower in the cohorts of 45-, 50-, 55-, and 60-year-old women. The RR of having Candida was higher for Surinamese women (1.24; CI 1.08-1.42). Furthermore, the RR of having mild dysplasia was higher for Surinamese women (1.47; CI 1.14-1.89) and for women born in other countries than in The Netherlands, Turkey, and Morocco (1.36; CI 1.13-1.62). No statistically significant relationship between (pre)neoplasia and Candida was observed. C. vaginalis is more frequent among Surinamese women. Presence of Candida is not associated with an increased risk for squamous abnormalities; therefore, women carrying Candida are not at an increased risk of developing cervical cancer.

Women testing positive for human papillomavirus (HPV) infection experience increased levels of anxiety that have been attributed to fears of stigmatization and developing cervical cancer. The objective of this study was to investigate the association between HPV infection and anxiety in women who were unaware they had been tested specifically for HPV, to determine if any anxiety experienced by HPV-positive women could be due to causes other than learning of test results. This study was nested within a randomised controlled trial of management of women with abnormal cervical cytology conducted in the United Kingdom with recruitment between 1999 and 2002. At baseline, prior to having a sample taken for HPV testing, the results of which were not disclosed, women were assessed for anxiety using the Hospital Anxiety and Depression Scale and asked about fears of developing cervical cancer ("cancer worries"); this assessment was repeated at 12, 18, 24, and 30 months of follow-up. Logistic regression and generalized estimating equations were used for the cross-sectional (baseline) and longitudinal analyses, respectively. Among the 2842 participants, there was no association between HPV status and anxiety among white women. Among non-white women, however, anxiety was less common among HPV-positive than HPV-negative women (adjusted odds ratio 0.41, 95% confidence interval 0.22 to 0.77). Among non-smokers, cancer worry was more common in HPV-positive than HPV-negative women; the opposite association was observed among ex-smokers. Associations between HPV status and anxiety may be explained by factors other than learning of test results and may vary by ethnicity and lifestyle factors.

Purpose Women with abnormal cervical cancer screening results are referred to colposcopy and biopsy for diagnosis of cervical cancer precursors (high-grade squamous intraepithelial lesions [HSILs]). Colposcopy with a single biopsy can miss identification of HSILs. No systematic study has quantified the improved detection of HSIL by taking multiple lesion-directed biopsies. Methods The Biopsy Study was an observational study of 690 women referred to colposcopy after abnormal cervical cancer screening results. Up to four directed biopsies were taken from distinct acetowhite lesions and ranked by colposcopic impression. A nondirected biopsy of a normal-appearing area was added if fewer than four directed biopsies were taken. HSIL identified by any biopsy was the reference standard of disease used to evaluate the incremental yield and sensitivity of multiple biopsies. Results In the overall population, sensitivities for detecting HSIL increased from 60.6% (95% CI, 54.8% to 66.6%) from a single biopsy to 85.6% (95% CI, 80.3% to 90.2%) after two biopsies and to 95.6% (95% CI, 91.3% to 99.2%) after three biopsies. A significant increase in sensitivity of multiple biopsies was observed in all subgroups. The highest increase in yield of HSIL was observed for women with a high-grade colposcopic impression, HSIL cytology, and human papillomavirus (HPV) type 16 positivity. Only 2% of all HSILs diagnosed in the participants were detected by biopsies of normal-appearing transformation zone. Conclusion Collection of additional lesion-directed biopsies during colposcopy increased detection of histologic HSIL, regardless of patient characteristics. Taking additional biopsies when multiple lesions are present should become the standard practice of colposcopic biopsy. PMID:25422481

Cervical vertigo and dizziness after whiplash injury.

Whiplash injury is not only limited to neck injury but also brainstem injury that does not involve direct damage to the neck or head. The symptoms of whiplash injury are polymorphous, with the most common complaints being cervical pain, headache and scapulodynia. Vertigo and dizziness are also reported in 25-50% of the cases. In otoneurologic studies, magnetic resonance angiography (MRA) is used for the evaluation of vertebrobasilar hemodynamics in patients who complain of dizziness and vertigo. It is reported that vertebrobasilar artery insufficiency (VBI) leads to brainstem and cerebellar ischemia and infarction following cervical manipulation. Here we examined the correlation between vertigo or dizziness and the right and left side difference in vertebral arteries after whiplash injury using MRA. We studied 20 patients who complained of neck pain with vertigo or dizziness after whiplash injury and 13 healthy volunteers as a control. In the control group, abnormal MRA findings in the vertebral arteries such as occlusion, stenosis or slow blood flow were seen in 77% of the cases. In the patient group, abnormal MRA findings were seen in 60%. The side difference in blood flow was 3.5+/-2.5 cm/s in the control group and 6.1+/-3.0 cm/s in the patient group. Our findings suggest that some subjects with persistent vertigo or dizziness after whiplash injury are more likely to have VBI on MRA. VBI might be an important background factor to evoke cervical vertigo or dizziness after whiplash injury. The side difference between the two vertebral arteries could cause a circulation disorder in the vertebrobasilar system after whiplash injury. However, the VBI on MRA itself was also seen in the control group, and thus it is not clear whether it is due to whiplash injury in the patient group.

The US Food and Drug Administration has approved marketing of the Prentif cavity-rim cervical cap. This contraceptive device is being distributed in the US and Canada by Cervical Cap Ltd, Los Gatos, California. The Prentif cap is available in 4 sizes: 22, 25, 28, and 31 mm inside diameter, with a length of 1 1/4-1 1/2 inches. In a multicenter trial involving 522 diaphragm users and 581 cap users followed for 2 years, the cap was 82.6% effective and the diaphragm was 83.3% effective in preventing pregnancy. When pregnancies attributable to user failure were excluded, these rates were increased to 93.6% for the cap and 95.4% for the diaphragm. 4% of cap users compared with only 1.7% of diaphragm users in this study developed abnormal Pap smears after 3 months of use; in addition, a higher proportion of cap users became infected with Gardnerella vaginalis and Monilia. Theoretical hazards include toxic shock syndrome and endometriosis due to backflow of menstrual fluids. Cap users are advised to undergo a Pap test after 3 months of use and discontinue cap use if the results are abnormal. The cap should not be used during menstruation. Although the cap can be left in place for up to 48 hours, its position should be checked before and after each episode of intercourse. The cervical cap requires less spermicide than the diaphragm and is not as messy. In addition, it can be left in the vagina twice as long as the diaphragm, without additional spermicide. Since the cap is smaller than the diaphragm and does not cover the vaginal wall, some women find intercourse more pleasurable with this device.

Cervical cancer screening in women younger than 30 years relies on cervical cytology because of the poor performance of human papillomavirus (HPV) DNA testing in this age group. To determine the performance of in-cell HPV E6, E7 mRNA quantification (HPV OncoTect) for the detection of high-grade cervical intraepithelial neoplasia in women younger than 30 years. We analyzed 3133 cytology specimens from a screening population of women aged 19-75 years investigate HPV OncoTect as a triage/secondary screening test for atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesion (LSIL) cytology in women younger than 30 years. Test results were compared to histology in 246 cases. The sensitivity of E6, E7 mRNA was 89% for CIN 2+ and 100% for CIN 3+ lesions in women 30 years and older. In women younger than 30 years, the sensitivity of E6, E7 mRNA for CIN 2+ lesions was 88% for CIN 2+ and 92% for CIN 3+ lesions. Abnormal cytology (≥ASCUS) exhibited a sensitivity of 89% for CIN 2+ and 100% for CIN 3+ in women 30 years and older and 96% sensitivity for CIN 2+ and 93% sensitivity for CIN 3+ in women younger than 30. The specificity of E6, E7 mRNA was >80% for CIN 2+ and CIN 3+ in both groups of women compared to a specificity of abnormal cytology of <10% for CIN 2+ and CIN 3+ in both groups. HPV OncoTect demonstrates a performance that would be effective for ASCUS/LSIL triage in women including those younger than 30 years.

HPV infection is associated with cervical cancer, one of the major public health problems in developing countries. In the Republic of Congo, despite of the high age-standardized incidence rate estimated at 25.2 per 100,000 women, molecular epidemiology data on HPV infections are very limited. We investigated HPV genotypes distribution in cervical smears among patients attending the General Hospital of Loandjili, Southwest Congo. A cross-sectional hospital-based study was conducted on 321 women. Liquid-based cytology samples were collected for cytological diagnosis and HPV detection. Nested-PCR was performed using MY09/MY11 and GP5+/GP6+ primers with genotyping by direct sequencing. Type-specific PCR for HPV-6, -11, -16, -18, -31 and -33 was also used to assess multiple infections. Out of 321 women examined, 189 (58.8%) had normal cytology, 16 (5.0%) had ASCUS and 116 (36.1%) had cytological abnormalities. HPV-DNA was detected in 22 (11.6%), 6 (37.5%), and 104 (89.6%) normal cytology, ASCUS and cytological abnormalities respectively. HPV16 was the most prevalent genotype regardless of cytological status followed by HPV70 in women without lesions and HPV33 among those with lesions. HR-HPV prevalence varied significantly according to the cervical cytology (P = 0.000). Among women without lesions, two peaks of HPV infections were observed in age group less than 30 years (60.0%) and in age group 50-59 years (7.1%). Age, age of first sex, multiple sexual partners and pregnancies were the risk factors for HPV infection in women without lesions. Our findings could be used as evidence data base for future epidemiological monitoring in this region. © 2015 Wiley Periodicals, Inc.

Infection with high-risk human papilloma viruses (HR-HPV), especially types 16/18, is the main factor in cervical carcinogenesis. Although the incidence of cervical cancer in Serbia is among the highest ones in Europe, data about HPV infection are insufficient. The aim of this study was to investigate the presence of overall and HPV16/18 infections in women with healthy appearance and cytologically (Pap) normal cervix. The study was performed on women who participated in this cervical cancer screening pilot study. Cervical HPV infection was detected by GP5+/6+ PCR. HPV16/18 were detected by amplification of E7/E1 viral gene, respectively. In 350 women we got the following results: cytological abnormalities (10.3%); visible cervical changes (20.3%); previous precancerous lesion (2.3%); normal Pap and speculum finding without history of precancerous lesion (67.1%). In the last group overall HPV prevalence was 41.3%, with 10.5% HPV16 and 23.7% HPV18. The rate of multiple HPV16 plus HPV18 infections was 2.6%. HR-HPV16/18 comprised 31.6% of the total HPV positive participants. Owing to the high prevalence of overall and HPV16/18 infections in women with healthy appearance and cytologically normal cervix, we postulate that testing/ prophylaxis for these HR-HPV types could be introduced in cervical cancer screening and preventive programmes in Serbia.

Chlamydia trachomatis (CT) is the most common bacterial cause of sexually transmitted disease. High-risk human papillomavirus (HR-HPV) is considered the main etiological agent for cervical neoplasia. Evidences showed that the presence of co-infection of CT and HR-HPV plays a central role in the etiology of cervical intraepithelial neoplasia (CIN) and cervical cancer. The goals of this study were: evaluate the human papillomavirus (HPV) and CT prevalence among Brazilian women with abnormal cytology and provide the effect of this association on the severity of cervical neoplasia. The population of this study was composed by 142 women with incident histological incidence of CIN grades I, II, III or cervical cancer from Recife, Northeast of Brazil. The polymerase chain reaction method on a cervical brush specimen was used to detect both agents and the automatic sequencing method was used for HPV genotyping assay. The prevalence of HPV and CT was 100 and 24.65 %, respectively. Thirteen types of HPV were detected; HPV 16, 18, 31 and 33 were the most common. The most prevalent HPV types were HPV 16 and 18. A significant association between CT positive and HPV 16 infection was found (p < 0.0106; OR = 5.31; 95 % IC 1.59-17.67). In the study population, there was diversity of HPV infections, with high-risk types being the most common. Also, the data collected suggest that CT infection may play an important role in the natural history of HPV infection.

Socio-demographic characteristics influencing cervical cancer screening intention of HIV-positive women in the central region of Ghana.

The burden of HIV and cervical cancer is concentrated in sub-Saharan Africa. Women with HIV are more likely to have persistent HPV infection leading to cervical abnormalities and cancer. Cervical cancer screening seems to be the single most critical intervention in any efforts to prevent cervical cancer. The purpose of this study was to determine the socio-demographic factors influencing intention to seek cervical cancer screening by HIV-positive women in the Central Region of Ghana. A descriptive cross-sectional study involving a convenience sample of 660 HIV-positive women aged 20 to 65 years receiving antiretroviral therapy in HIV care centres in the Central Region of Ghana was conducted using an interviewer-administered questionnaire. The data were summarised and analysed using frequencies, percentages and binary logistic regression. The study revealed that 82.0% of HIV-positive women intended to obtain cervical cancer screening. Level of education was a determinant of cervical cancer screening intention. HIV-positive women with low levels of education were 2.67 times (95% CI, 1.61-4.42) more likely to have intention to screen than those with no formal education. Those with high levels of education were 3.16 times (95% CI, 1.42-7.02) more likely to have intention to screen than those with no formal education. However, age, religion, marital status, employment status, and ability to afford the cost of cervical cancer screening were not determinants of intention to screen. Education of women of all ages needs to be a priority, as it could enable them to adopt appropriate health behaviours and engage in cervical cancer screening. Additionally, interventions to improve understanding of cervical cancer screening among HIV-positive women are highly recommended. These include health education about the disease and availability of screening options in HIV/AIDS care centres.

The incidences of genital human papillomavirus (HPV) infection, associated squamous intraepithelial lesions and cervical squamous cell carcinoma are significantly increased in HIV-positive women. The role of other cervicovaginal infections in the acquisition of the HPV infection, cervical carcinogenesis and genital HIV infection remains largely speculative. A retrospective study was conducted including 1087 HIV-positive women in rural Mpumalanga province, South Africa, for the period 1 May 2009 to 31 August 2010. For each patient, the age at first presentation, cervical cytological diagnosis, subsequent follow-up cytology and histology, and microscopically visible infections (including endemic Bilharzia) were tabulated and statistically analysed. The prevalence of low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL), squamous cell carcinoma, atypical squamous cells of undetermined significance (ASC-US) and atypical squamous cells, cannot exclude HSIL (ASC-H) in the study population were 22.1%, 30.9%, 0.6%, 13.5% and 4.0%, respectively. LSIL, HSIL and squamous cell carcinoma were diagnosed, respectively, at the average ages of 35.7, 37.9 and 37.2 years. Four patients with cervical intraepithelial neoplasia grade 1 (CIN1), 32 with CIN2/CIN3 and two with cervical squamous cell carcinoma were also diagnosed with Bilharzia. Of the other infections only bacterial vaginosis had a positive statistical correlation with HPV-induced cervical abnormalities (LSIL, HSIL or squamous cell carcinoma). This study confirms the high prevalence of progressive HPV-associated cervical disease in a rural Southern African HIV-positive population, which is at least equal to or worse than in other African HIV-positive studies. The high incidence of Bilharzia infection in those cases that underwent cervical cone excision suggests a possible relationship with progressive HPV disease and cervical carcinogenesis. Bacterial vaginosis (perhaps in combination with Bilharzia) may compromise the normal barriers against HPV and HIV infection. © 2012 John Wiley & Sons Ltd.

The aim is to evaluate the clinical application value and correlation with cervical lesions' progression of human papillomavirus (HPV) E6/E7 mRNA test in women with atypical squamous cells of undetermined significance (ASCUS/borderline) or low-grade squamous intraepithelial lesions (LSILs/mild dyskaryosis) cytological abnormalities. A meta-analysis was conduct by searching China National Knowledge Infrastructure (1979-2016), Wanfang Date (1998-2016), VIP (1989-2016), PubMed (1950-2016), Web of Science (1950-2016) and Elsevier Science Direct (1998-2016), for studies on effect of HPV E6/E7 mRNA detection in women with ASCUS/LSIL/dyskaryosis. Study selection and appraisal were conducted independently by three authors, according to inclusive and exclusive criteria. Then, a meta-analysis was performed using the RevMan4.2 software. The subgroups analysis was conducted according to women's initial HPV DNA test results. Six articles with a total of 1024 subjects were included in the study. It was concluded that a positive HPV E6/E7 mRNA tested result have a higher risk of progressing to CIN2+ in future 2 years than a negative result. The pooled relative risk (RR) is 3.08, (95% confidence interval [CI] = 1.57-6.07, P < 0.05). The same situation was also observed in the subgroup of HPV DNA tested positive group and HPV DNA tested unlimited group. The pooled RR value of the two subgroups was, respectively, 1.98, (95% CI = 1.19-1.19, P < 0.05) and 7.58, (95% CI = 3.64-3.64, P < 0.05). A positive HPV E6/E7 mRNA testing result suggested the women with ASCUS, or LSIL Pap smear was in a truly dangerous position, which is an adverse prognostic factor. It suggested that cervical lesions stay in a progressing status and these women should be referred for colposcopy and strengthen follow-up promptly. Whereas, women with a negative HPV E6/E7 mRNA testing result can increase follow-up interval, by comprehensively considering their situation, thus, avoiding unnecessary colposcopy and reducing the rate of colposcopy and biopsy.

We aimed at investigating the association between T-wave axis deviation, metabolic syndrome (MetS), its components and estimated risk of cardiovascular disease (CVD) at 10 years in an adult Italian population. 11,143 women (54 ± 11 years) and 9742 men (55 ± 11 years) were analyzed from the Moli-sani cohort, randomly recruited from the general population. MetS was defined using the ATPIII criteria. T-wave axis deviation was measured from the standard 12-lead resting electrocardiogram. CVD risk in ten years was estimated by the CUORE score. 29% of men and 27% of women with MetS showed borderline or abnormal T-wave as compared to 24% and 17% without MetS (p < 0.0001 for both genders). Among components of MetS, elevated waist and blood pressure were strongly associated with T-wave axis deviation, whereas glucose, HDL and triglycerides were only marginally. The odds of having borderline or abnormal T-wave axis deviation in multivariable regression analysis, was 1.38 (95% CI:1.25-1.53) in MetS men and 1.68 (95% CI:1.51-1.87) in MetS women compared to those without. Further adjustment for MetS components completely abolished the associations. Abnormal T-wave axis deviation was associated with an increased risk of CVD in 10 years in men (OR = 4.4; 95% CI:1.10-17.9). T-wave axis deviation is strongly associated with components of the MetS, in particular high waist circumference and blood pressure and with an increased CVD risk, particularly in men. ECG monitoring to identify T-wave axis deviation in obese, hypertensive or MetS subjects can be an early indicator of vascular disease and help in reducing cardiac events.

Appropriate mechanical function of the uterine cervix is critical for maintaining a pregnancy to term so that the fetus can develop fully. At the end of pregnancy, however, the cervix must allow delivery, which requires it to markedly soften, shorten and dilate. There are multiple pathways to spontaneous preterm birth, the leading global cause of death in children less than 5 years old, but all culminate in premature cervical change, because that is the last step in the final common pathway to delivery. The mechanisms underlying premature cervical change in pregnancy are poorly understood, and therefore current clinical protocols to assess preterm birth risk are limited to surrogate markers of mechanical function, such as sonographically measured cervical length. This is what motivates us to study the cervix, for which we propose investigating clinical cervical function in parallel with a quantitative engineering evaluation of its structural function. We aspire to develop a common translational language, as well as generate a rigorous integrated clinical-engineering framework for assessing cervical mechanical function at the cellular to organ level. In this review, we embark on that challenge by describing the current landscape of clinical, biochemical, and engineering concepts associated with the mechanical function of the cervix during pregnancy. Our goal is to use this common platform to inspire novel approaches to delineation of normal and abnormal cervical function in pregnancy. PMID:25841293

In patients with lesions of the cervical spine, direct laryngoscopy for endotracheal intubation entails the risk of injuring the spinal cord. In an attempt to avoid this complication, the authors used flexible fiberoptic nasal intubation in a series of 327 patients with cervical lesions undergoing elective neurosurgical procedures. The nasal route was preferred for laryngeal intubation because it is easier than the oral route and a restraining collar or halo device does not impair the intubating maneuver. Bronchoscopic intubation was possible in all patients. In 12 patients (3.6%), anatomic abnormalities prevented transnasal insertion of the endotracheal tube, and transoral fiberoptic intubation was necessary. Endotracheal intubation was graded as slightly difficult in 85 patients (26%). The minimal peripheral oxygen saturation during intubation exceeded 90% in 289 patients (88%). In the other 38 patients, the mean O2 saturation was 84.2+/-4.3% (range, 72-89%). Intubation was well tolerated by all patients and none had recall of the procedure. Cervical stabilizers did not have to be removed for intubation in any patient. None of the patients had postoperative neurologic deficits attributable to the intubation procedure. The authors consider fiberoptic transnasal intubation to be a useful alternative to direct laryngoscopic tracheal intubation in patients undergoing elective surgical procedures on the cervical spine to avoid potential injury to the cervical spinal cord.

Injuries to the cervical spine in pediatric patients are uncommon. A missed injury can have devastating consequences in this age group. Because of the lack of routine in diagnosis and management of pediatric cervical spine injuries (PCSI), each of these cases represents a logistic and personal challenge. By means of clinical cases, we demonstrate key points in diagnostics and treatment of pediatric spine injuries. We highlight typical pediatric injury patterns and more adult-like injuries. The most common cause of injury is blunt trauma. There is an age-related pattern of injuries in pediatric patients. Children under the age of 8 frequently sustain ligamentous injuries in the upper cervical spine. After the age of 8, the biomechanics of the cervical spine are similar to adults, and therefore, bony injuries of the subaxial cervical spine are most likely to occur. Clinical presentation of PCSI is heterogeneous. Younger children can neither interpret nor communicate neurological abnormalities, which make timely and accurate diagnosis difficult. Plain radiographs are often misinterpreted. We find different types of injuries at different locations, because of different biomechanical properties of the immature spine. We outline that initial management is crucial for long-term outcome. Knowledge of biomechanical properties and radiographic presentation of the immature spine can improve the awareness for PCSI. Diagnosis and management of pediatric patients after neck trauma can be demanding. Level IV.

It is important to detect cervical dysplasia, Cervical Intraepithelial Neoplasia (CIN). CIN is the potentially premalignant and abnormal squamous cells on surface of cervix. In this study, the spatial frequency spectra of pre-cancer cervical tissues are used to detect differences among different grades of human cervical tissues. Seven sets of thick tissue sections of human cervix of normal, CIN 1, CIN 2, and CIN 3 tissues are studied. The confocal microscope images of the stromal region of normal and CIN human tissues were analyzed using Fast Fourier Transform (FFT) to generate the spatial spectra. It is observed that higher frequency components exist in CIN tissues than those in normal tissue, as well as those in higher grade CIN tissue than those in lower grade CIN tissue. The width of the spatial frequency of different types of tissues is used to create a criterion for CIN grading by training a support vector machine (SVM) classifier. The results show that the randomness of tissue structures from normal to different stages of precancer in cervical tissue can be recognized by fingerprints of the spatial frequency. The efficacy of spatial frequency analysis for CIN grading is evaluated as excellent since high AUC (area under the ROC curve), sensitivity and specificity are obtained by the statistics study. This works lays the foundation of using spatial frequency spectra for a histology evaluation.

The cervical cancer screening at a pre-cancer stage is beneficial to reduce the mortality of women. An opto-electronic joint detection system based on DSP aiming at early cervical cancer screening is introduced in this paper. In this system, three electrodes alternately discharge to the cervical tissue and three light emitting diodes in different wavelengths alternately irradiate the cervical tissue. Then the relative optical reflectance and electrical voltage attenuation curve are obtained by optical and electrical detection, respectively. The system is based on DSP to attain the portable and cheap instrument. By adopting the relative reflectance and the voltage attenuation constant, the classification algorithm based on Support Vector Machine (SVM) discriminates abnormal cervical tissue from normal. We use particle swarm optimization to optimize the two key parameters of SVM, i.e. nuclear factor and cost factor. The clinical data were collected on 313 patients to build a clinical database of tissue responses under optical and electrical stimulations with the histopathologic examination as the gold standard. The classification result shows that the opto-electronic joint detection has higher total coincidence rate than separate optical detection or separate electrical detection. The sensitivity, specificity, and total coincidence rate increase with the increasing of sample numbers in the training set. The average total coincidence rate of the system can reach 85.1% compared with the histopathologic examination.

Objectives To investigate the clinical utility of VEMPs in patients suffering from unilateral vestibular schwannoma (VS) and to determine the optimal stimulation parameter (air conducted sound, bone conducted vibration) for evaluating the function of the vestibular nerve. Methods Data were obtained in 63 patients with non-operated VS, and 20 patients operated on VS. Vestibular function was assessed by caloric, cervical and ocular VEMP testing. 37/63 patients with conclusive ACS ocular VEMPs responses were studied separately. Results In the 63 non-operated VS patients, cVEMPs were abnormal in 65.1% of patients in response to AC STB and in 49.2% of patients to AC clicks. In the 37/63 patients with positive responses from the unaffected side, oVEMPs were abnormal in 75.7% of patients with ACS, in 67.6% with AFz and in 56.8% with mastoid BCV stimulation. In 16% of the patients, VEMPs were the only abnormal test (normal caloric and normal hearing). Among the 26 patients who did not show oVEMP responses on either side with ACS, oVEMPs responses could be obtained with AFz (50%) and with mastoid stimulation (89%). Conclusions The VEMP test demonstrated significant clinical value as it yielded the only abnormal test results in some patients suffering from a unilateral vestibular schwannoma. For oVEMPs, we suggest that ACS stimulation should be the initial test. In patients who responded to ACS and who had normal responses, BCV was not required. In patients with abnormal responses on the affected side using ACS, BCV at AFz should be used to confirm abnormal function of the superior vestibular nerve. In patients who exhibited no responses on either side to ACS, BCV was the only approach allowing assessment of the function of the superior vestibular nerve. We favor using AFz stimulation first because it is easier to perform in clinical practice than mastoid stimulation. PMID:25137289

Cytomegalovirus (CMV) infection in immunocompetent hosts is generally asymptomatic or may present as a mononucleosic syndrome. Its association with acute cervicitis and vulvovaginitis has rarely been reported. A 24-year-old woman presented with pelvic pain, vulvodynia, abnormal vaginal discharge, burning with urination, fatigue, fever, vomiting and diarrhoea. The vulva and cervix were red with vesicular lesions on the cervix. Genital herpes simplex infection (HSV) was suspected and valacyclovir was given orally. However, serial viral cultures performed 7 weeks apart did not isolate HSV as suspected, but CMV was confirmed by immunofluorescence and early antigen research. Blood tests confirmed an acute CMV infection. Typical inclusions were found at histology. Symptoms resolved slowly with persistence of cervical lesions at 7 weeks from diagnosis. The frequency of CMV genital infection is probably underestimated. The infection is not always asymptomatic and might be confused with genital HSV infection. The clinical course is longer.

Cervical intraepithelial neoplasia (CIN) is the precursor of invasive cervical cancer and associated with human papillomavirus (HPV) infection. Photodynamic therapy (PDT) is a technique that has been used for the treatment of tumors. PDT is based on the accumulation of a photosensitizer in target cells that will generate cytotoxic reactive oxygen species upon illumination, inducing the death of abnormal tissue and PDT with less damaging to normal tissues than surgery, radiation, or chemotherapy and seems to be a promising alternative procedure for CIN treatment. The CIN high grades (II and III) presents potential indications for PDT due the success of PDT for CIN low grade treatment. The patients with CIN high grade that were treated with new clinic protocol shows lesion regression to CIN low grade 60 days after the treatment. The new clinical protocol using for treatment of CIN high grade shows great potential to become a public health technique.

Cervical cystic lymphangioma (CCL) is a rare and benign tumour involving congenital and cystic abnormalities derived from lymphatic vessels. The most accepted treatment continues to be surgical excision. However, when this infiltrates vital neurovascular neck structures, complete excision is difficult and if only partial, the recurrence rate is very high. The most frequently used alternative treatment is to inject sclerosants into the lesion. The use of these techniques has reported good results in children; however, there are few references thereof with regard to adults. We are reporting on a cervical cystic lymphangioma in a male aged 22, treated with an intra-lesion injection of 20 cc with 0.01 mg/cc dilution of OK-432 (picibanil) in physiological serum. Sole complications were fever and local reaction where the solution was injected. One month after treatment the lymphangioma had totally remitted and sixteen months later continues in remittance.

The PAPNET System is the only device with a neural-network-based-artificial intelligence to detect and show the images of abnormal cells on the monitor to be evaluated in an interactive way. We effectively used the PAPNET in rescreening of conventional cervical smears and we detected its advantages and its disadvantages. In this paper, we report our results from PAPNET-assisted primary screening performed on 20,154 conventional smears. The smears were classified as Negative or as Review. The Negative cases were rapidly rescreened mainly near the coverslip edges, which are the slide areas not analyzed by automated devices because of focusing problems. The Review cases were fully reanalyzed by the optic microscope. In summary, 140 positive smears were detected: 57 cases showed changes due to HPV, 63 LSIL, 15 HSIL, and 5 carcinomas. Therefore, the PAPNET System was confirmed as useful in primary screening of conventional cervical samples as well as rescreening.

In 2000, the REACH Boston 2010 Breast and Cervical Cancer Coalition conducted a community needs assessment and found several factors that may have contributed to disproportionately high breast and cervical cancer mortality among black women: (a) Focus group participants reported that many women in their communities had limited awareness about risk factors for cancer as well as about screening. (b) Black women experienced barriers to care related to the cultural competence of providers and of institutions. (c) Black women were not receiving adequate follow-up for abnormal mammograms and Pap smears. The Coalition's Community Action Plan to address disparities includes a model primary care service for black women; scholarships to increase the number of black mammogram technologists; primary care provider and radiology technologist training about disparities and cultural competence; and education to increase awareness among black women and to increase leadership and advocacy skills.

Several functional neuroimaging studies have demonstrated abnormalities in fronto-limbic pathways when comparing borderline personality disorder (BPD) patients with controls. The present study aimed to evaluate regional cerebral metabolism in euthymic BPD patients with similar measured impulsivity levels by means of 18F-FDG PET during resting state and to compare them against a control group. The present study evaluates regional cerebral metabolism in 8 euthymic BPD patients with 18F-FDG PET during resting state as compared to 8 controls with similar socio-geographic characteristics. BPD patients presented a marked hypo-metabolism in frontal lobe and showed hyper-metabolism in motor cortex (paracentral lobules and post-central cortex), medial and anterior cingulus, occipital lobe, temporal pole, left superior parietal gyrus and right superior frontal gyrus. No significant differences appeared in basal ganglia or thalamus. Results reveal a dysfunction in patients' frontolimbic network during rest and provide further evidence for the importance of these regions in relation to BPD symptomatology.

Increased accessibility and rapidity of computed tomography (CT) have led to increased use and radiation exposure to pediatric trauma patients. The thyroid is radiosensitive and therefore at risk for developing malignancy from radiation exposure during cervical spine CT. This analysis aimed to determine which preelementary trauma patients warrant cervical spine CT by defining incidence and clinical characteristics of preelementary cervical spine injury. This was a retrospective review of pre-elementary trauma patients from 1998 to 2010 with cervical spine injury admitted to a Level I trauma center. Patients were identified from the trauma registry using DRG International Classification of Diseases-9th Rev. codes and reviewed for demographics, mechanism of injury, clinical presentation, injury location, injury type, treatment, and outcome. A total of 2,972 preelementary trauma patients were identified. Twenty-two (0.74%) had confirmed cervical spine injuries. Eleven (50%) were boys, and the mean (SD) age was 3 (1.7) years. The most common mechanism of injury was motor vehicle collision (n = 16, 73%). The majority (59%) were in extremis, and 12 (55%) arrived intubated. The median Glasgow Coma Scale (GCS) score was 3 (interquartile range, 3-10); the median Injury Severity Score (ISS) was 33 (interquartile range, 17-56). Nineteen injuries (76%) were at the level of C4 level and higher. The mortality rate was 50%. All patients had clinical findings suggestive of or diagnostic for cervical spine injury; 18 (82%) had abnormal neurologic examination result, 2 (9%) had torticollis, and 2 (9%) had neck pain. The incidence of cervical spine injury in preelementary patients was consistent with previous reports. Missing a cervical spine injury in asymptomatic preelementary patients is extremely low. Reserving cervical spine CT to symptomatic preelementary patients would decrease unnecessary radiation exposure to the thyroid. Therapeutic study, level IV.

The present study was designed to compare abnormality detection rates using DSP30 + IL2 and 12-O-Tetradecanoylphorbol-13-acetate (TPA) in Asian patients with B-CLL. Hematological specimens from 47 patients (29 newly diagnosed, 18 relapsed) were established as 72 h-DSP30 + IL2 and TPA cultures. Standard methods were employed to identify clonal aberrations by conventional cytogenetics (CC). The B-CLL fluorescence in situ hybridization (FISH) panel comprised ATM, CEP12, D13S25, and TP53 probes. DSP30 + IL2 cultures had a higher chromosomal abnormality detection rate (67 %) compared to TPA (44 %, p < 0.001). The mean number of analyzable metaphases and abnormal metaphases per slide was also higher (p < 0.005, p < 0.001, respectively). Culture success rate, percentage of complex karyotype, and percentage of non-clonal abnormal cell were not significantly different (p > 0.05). Thirteen cases with abnormalities were found exclusively in DSP30 + IL2 cultures compared to one found solely in TPA cultures. DSP30 + IL2 cultures were comparable to the FISH panel in detecting 11q-, +12 and 17p- but not 13q-. It also has a predilection for 11q- bearing leukemic cells compared to TPA. FISH had a higher abnormality detection rate (84.1 %) compared to CC (66.0 %) with borderline significance (p = 0.051), albeit limited by its coverage. In conclusion, DSP30 + IL2 showed a higher abnormality detection rate. However, FISH is indispensable to circumvent low mitotic indices and detect subtle abnormalities.

Contemporary theories for the aetiology of borderline personality disorder (BPD) take a lifespan approach asserting that inborn biological predisposition is potentiated across development by environmental risk factors. In this review, we present and critically evaluate evidence on the neurobiology of BPD in childhood and adolescence, compare this evidence to the adult literature, and contextualise within a neurodevelopmental framework. A systematic review was conducted to identify studies examining the neurobiological (i.e. genetic, structural neuroimaging, neurophysiological, and neuropsychological) correlates of BPD symptoms in children and adolescents aged 19 years or under. We identified, quality assessed, and narratively summarised 34 studies published between 1980 and June 2016. Similar to findings in adult populations, twin studies indicated moderate to high levels of heritability of BPD, and there was some evidence for gene-environment interactions. Also consistent with adult reports is that some adolescents with BPD demonstrated structural (grey and white matter) alterations in frontolimbic regions and neuropsychological abnormalities (i.e. reduced executive function and disturbances in social cognition). These findings suggest that neurobiological abnormalities observed in adult BPD may not solely be the consequence of chronic morbidity or prolonged medication use. They also provide tentative support for neurodevelopmental theories of BPD by demonstrating that neurobiological markers may be observed from childhood onwards and interact with environmental factors to increase risk of BPD in young populations. Prospective studies with a range of repeated measures are now required to elucidate the temporal unfurling of neurobiological features and further delineate the complex pathways to BPD.

Abnormal brain volume has been frequently demonstrated in major depressive disorder (MDD). It is unclear if these findings are specific for MDD since aberrant brain structure is also present in disorders with depressive comorbidity and affective dysregulation, such as borderline personality disorder (BPD). In this transdiagnostic study, we aimed to investigate if regional brain volume loss differentiates between MDD and BPD. Further, we tested for associations between brain volume and clinical variables within and between diagnostic groups. 22 Females with a DSM-IV diagnosis of MDD, 17 females with a DSM-IV diagnosis of BPD and without comorbid posttraumatic stress disorder, and 22 age-matched female healthy controls (HC) were investigated using magnetic resonance imaging. High-resolution structural data were analyzed using voxel-based morphometry. A significant (p<0.05, cluster-corrected) volume decrease of the anterior cingulate cortex (ACC) was found in MDD compared to HC, as opposed to volume decreases of the amygdala in BPD compared to both HC and MDD. Sensitivity and specificity of regional gray matter volume for a diagnosis of MDD were modest to fair. Amygdala volume was related to depressive symptoms across the entire patient sample. Potential limitations of this study include the modest sample size and the heterogeneous psychotropic drug treatment. ACC volume reduction is more pronounced in MDD with an intermediate degree of volume loss in BPD compared to HC. In contrast, amygdala volume loss is more pronounced in BPD compared to MDD, yet amygdala volume is associated with affective symptom expression in both disorders. Copyright © 2014 Elsevier B.V.

Behavioral problems and psychopathologies were reported in children exposed to the World Trade Center (WTC) attacks in New York City within 2-3 y post-disaster. Little is known of subsequent 9/11 related behavioral and emotional problems. We assessed risk factors for behavioral difficulties and probable posttraumatic stress disorder (PTSD) in 489 adolescent enrollees ages 11-18 y of age in the World Trade Center Health Registry cohort using the Strengths and Difficulties Questionnaire (SDQ) and DISC Predictive Scales (DPS), respectively, as reported by the adolescents. Associations between parental PTSD and adolescent PTSD and behavioral problems were studied in a subset of 166 adolescent-parent pairs in which the parent was also a Registry enrollee. Nearly one-fifth (17.4%) of the adolescents, all of whom were 5-12 y old at the time of the attacks, scored in the abnormal (5.7%) or borderline (11.7%) range of total SDQ. Problems were more frequent in minority, low-income, and single-parent adolescents. Abnormal and borderline SDQ scores were significantly associated with direct WTC exposures and with WTC-related injury or death of a family member. Adolescent PTSD was significantly associated with WTC exposure and with fear of one's own injury or death, and with PTSD in the parent (OR = 5.6; 95% CI 1.1-28.4). This adolescent population should be monitored for persistence or worsening of these problems. Co-occurrence of parent and child mental health symptoms following a disaster may have implications for healthcare practitioners and for disaster response planners.

Endogenous and exogenous cannabinoids bind to central cannabinoid receptors to control a multitude of behavioral functions, including aggression. The first main objective of this review is to dissect components of the endocannabinoid system, including cannabinoid 1 and cannabinoid 2 receptors; the endogenous cannabinoids anandamide and 2-arachidonoylglycerol; and the indirect cannabinoid modulators fatty acid amide hydrolase and monoacylglycerol lipase; that have shown abnormalities in basic research studies investigating mechanisms of aggression. While most human research has concluded that the active ingredient of marijuana, Δ9-tetrahydrocannabinol, tends to dampen rather than provoke aggression in acute doses, recent evidence supports a relationship between the ingestion of synthetic cannabinoids and emergence of violent or aggressive behavior. Thus, another objective is to evaluate the emerging clinical data. This paper also discusses the relationship between prenatal and perinatal exposure to cannabis as well as use of cannabis in adolescence on aggressive outcomes. A final objective of the paper is to discuss endocannabinoid abnormalities in psychotic and affective disorders, as well as clinically aggressive populations, such as borderline personality disorder and antisocial personality disorder. With regard to the former condition, decreased anandamide metabolites have been reported in the cerebrospinal fluid, while some preliminary evidence suggests that fatty acid amide hydrolase genetic polymorphisms are linked to antisocial personality disorder and impulsive-antisocial psychopathic traits. To summarize, this paper will draw upon basic and clinical research to explain how the endocannabinoid system may contribute to the genesis of aggressive behavior.

A colposcopy examination is the main management option for women with an abnormal cervical screening test result. Although some women experience adverse psychological effects after colposcopy, those at greatest risk are unknown. We investigated predictors of worries about cervical cancer, sex, future fertility and general health during 12 to 30 months after colposcopy. We invited 1,515 women, aged 20 to 59 years with low-grade cervical cytology who attended colposcopy to complete questionnaires at recruitment (∼8 weeks after cytology result) and after 12, 18, 24, and 30 months of follow up. Outcomes were worries about having cervical cancer, having sex, future fertility, and general health at any time during follow-up. Factors significantly associated with each outcome were identified using multiple logistic regression. At one or more time points during follow-up, 40% of women reported worries about having cervical cancer, 26% about having sex, 24% about future fertility, and 60% about general health. For all outcomes except sex, worries reported at recruitment were associated with significantly increased risk of worries during follow-up. Significant anxiety at recruitment was associated with all worries during follow-up. Women diagnosed with CIN2+ had significantly higher risks of worries about cervical cancer and future fertility. Management received was associated significantly with worries about cervical cancer and having sex. Younger women significantly more often reported worries about future fertility, whereas women who had children had reduced risk of future fertility worries but increased risk of cervical cancer worries. Clinical, sociodemographic, lifestyle, and psychological factors predicted risk of reporting worries after colposcopy. Copyright © 2015 Jacobs Institute of Women's Health. Published by Elsevier Inc.

OBJECTIVE: To assess the prevalence and potential risk factors associated with human papillomavirus (HPV) cervical infection among women residing in a region of northeastern Argentina with a high incidence of cervical cancer. METHODS: A case-control study of 330 women participating in a cervical cytological screening program conducted in Posadas city, Misiones, Argentina, from February 1997 to November 1998 was carried out. Standardized questionnaires were administered, and clinical examination including colposcopy was performed. Fresh endocervical specimens for HPV DNA detection by generic polymerase chain reaction were collected and the products typed by dot-blot hybridization. RESULTS: Human papillomavirus DNA was found in 61% of samples analyzed (185/301). Samples with normal cytology had a 43% infection rate (85/199), while those classified as low-grade squamous intraepithelial lesion, high-grade squamous intraepithelial lesion, and invasive cervical carcinoma had an infection rate of 96% (53/55), 100% (29/29), and 100% (18/18), respectively. Human papillomavirus typing showed a 64% (118/185) prevalence of type 16 among all the infected population analyzed; type 16 was detected among 49% (42/85) of infected samples with normal cytology and in an average of 74% (74/100) with abnormal cytology. Sexual behavior, residence in southern Paraguay, and history of a previous sexually transmitted diseases were the main risk factors associated with high-grade cervical lesions. CONCLUSIONS: An elevated prevalence of HPV infection was detected in this population, which also has a high incidence of cervical cancer. The broad distribution of high-risk HPV type 16 in women with normal cytology and colposcopy suggests that viral infection is an important determinant of regional cancer incidence. PMID:10524669

Objective: To identify the associated factors of cervical pre-malignant lesions among the married fisher women residing in the coastal areas of Sadras, Tamil Nadu. Methods: The study was conducted in five fishermen communities under Sadras, a coastal area in Tamil Nadu, India. Two hundred and fifty married fisher women residing in the area. Quantitative descriptive approach with a cross-sectional study design was used. Data were collected using a structured interview schedule for identifying the associated factors and Pap smear test was performed for identifying the pre-malignant cervical lesions among the married fisher women. Data were analyzed using descriptive and inferential statistics. Results: Among 250 women, about six (2.4%) of them presented with pre-cancerous lesions such as atypical squamous cell of undifferentiated significance (ASCUS) — five (2%) and mild dysplasia one (0.4%). Majority of the women, about 178 (71.2%) women, had abnormal cervical findings. Statistical analysis showed a significant association of risk factors such as advanced age, lack of education, low socioeconomic status, using tobacco, multiparity, premarital sex, extramarital relationship, using cloth as sanitary napkin, etc. Conclusion: The study findings clearly show the increased vulnerable state of the fisher women for acquiring cervical cancer as they had many risk factors contributing to the same.

Sexually transmitted human papillomavirus (HPV) is etiologically related to cervical carcinoma and a distinct subset of cancers of the nasopharyngeal tract. We report 2 patients with HPV-associated cervical cancer and synchronous diagnoses of HPV-related head and neck cancer of their husbands. These patients had active oral sex for more than 20 years. The first patient was a 64-year-old woman who had an abnormal Papanicolaou smear and was found to have squamous cell carcinoma of the cervix on cervical punched biopsy. Her husband was diagnosed with laryngeal squamous cell carcinoma 1 year previously, and was treated with total laryngectomy and adjuvant radiation. HPV-16 DNA was detected in both their tumor specimens using polymerase chain reaction. The other patient was a 50-year-old female with cervical carcinoma treated surgically and with concurrent chemo-radiotherapy. HPV-31 DNA was detected in her tumor specimen. Three years later, her husband presented with nasopharyngeal carcinoma, although not a tobacco or alcohol user. HPV-18 DNA was detected in his tumor specimen.These findings strongly suggest that HPV may play a major role in the carcinogenesis of urogenital and nasopharyngeal tumors and the transmission potential of orogenital sex.

MicroRNAs and siRNAs belong to a family of small noncoding RNAs which bind through partial sequence complementarity to 3′-UTR regions of mRNA from target genes, resulting in the regulation of gene expression. MicroRNAs have become an attractive target for genetic and pharmacological modulation due to the critical function of their target proteins in several signaling pathways, and their expression profiles have been found to be altered in various cancers. A promising technology platform for selective silencing of cell and/or viral gene expression using siRNAs is currently in development. Cervical cancer is the most common cancer in women in the developing world and sexually transmitted infection with HPV is the cause of this malignancy. Therefore, a cascade of abnormal events is induced during cervical carcinogenesis, including the induction of genomic instability, reprogramming of cellular metabolic pathways, deregulation of cell proliferation, inhibition of apoptotic mechanisms, disruption of cell cycle control mechanisms, and alteration of gene expression. Thus, in the present review article, we highlight new research on microRNA expression profiles which may be utilized as biomarkers for cervical cancer. Furthermore, we discuss selective silencing of HPV E6 and E7 with siRNAs which represents a potential gene therapy strategy against cervical cancer. PMID:25874209

To describe a case of cervical flexion myelopathy resulting from a drug overdose. A 56-year-old male presented to the emergency department unable to move his extremities following drug overdose. Neurological examination revealed him to be at C6 ASIA A spinal cord injury. The CT of his cervical spine revealed no fracture; however, an MRI revealed cord edema extending from C3 to C6 as well as posterior paraspinal signal abnormalities suggestive of ligamentous injury. The patient underwent a posterior cervical laminectomy and fusion from C3 to C7. Neurologically he regained 3/5 bilateral tricep function and 2/5 grip; otherwise, he remained at ASIA A spinal cord injury at 6 months. Our patient suffered a spinal cord injury likely due to existing cervical stenosis, and in addition to an overdose of sedating medications, he likely sat in flexed neck position for prolonged period of time with the inability to modify his position. This likely resulted in cervical spine vascular and/or neurological compromise producing an irreversible spinal cord injury. Spinal cord injury is a rare finding in patients presenting with drug overdose. The lack of physical exam findings suggestive of trauma may delay prompt diagnosis and treatment, and thus clinicians must have a high index of suspicion when evaluating patients in this setting.

Background: The objective of this study was to investigate the expression of human papilloma virus (HPV) L1 capsid protein in abnormal cervical cytology with HPV16 infection and analyze its association with cervical histopathology in Korean women. Material and Methods: We performed immunocytochemistry for HPV L1 in 475 abnormal cervical cytology samples from patients with HPV16 infections using the Cytoactiv® HPV L1 screening set. We investigated the expression of HPV L1 in cervical cytology samples and compared it with the results of histopathological examination of surgical specimens. Results: Of a total of 475 cases, 188 (39.6%) were immunocytochemically positive and 287 (60.4%) negative for HPV L1. The immunocytochemical expression rates of HPV L1 in atypical squamous cells of unknown significance (ASCUS), low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL), and cancer were 21.8%, 59.7%, 19.1%, and 0.0%, respectively. LSIL exhibited the highest rate of HPV L1 positivity. Of a total of 475 cases, the multiple-type HPV infection rate, including HPV16, in HPV L1-negative cytology samples was 27.5%, which was significantly higher than that in HPV L1-positive cytology samples (p = 0.037). The absence of HPV L1 expression in ASCUS and LSIL was significantly associated with high-grade (≥cervical intraepithelial neoplasia [CIN] 2) than low-grade (≤CIN1) histopathology diagnoses (p < 0.05), but was not significantly different between HPV16 single and multiple-type HPV infections (p > 0.05). On the other hand, among 188 HPV L1-positive cases, 30.6% of multiple-type HPV infections showed high-grade histopathology diagnoses (≥CIN3), significantly higher than the percentage of HPV16 single infections (8.6%) (p = 0.0004) Conclusions: Our study demonstrates that the expression of HPV L1 is low in advanced dysplasia. Furthermore, the absence of HPV L1 in HPV16-positive low-grade cytology (i.e., ASCUS and LSIL) is strongly associated with high-grade histopathology diagnoses. The multiplicity of HPV infections may have an important role in high-grade histopathology diagnoses (≥CIN3) in HPV L1-positive cases. PMID:24396289

Abnormal activation of the Wnt/β-catenin signaling pathway is common in human cancers, including cervical cancer. Many papers have shown that SRY (sex-determining region Y)-box (SOX) family genes serve as either tumor suppressor genes (TSGs) or oncogenes by regulating the Wnt signaling pathway in different cancers. We have demonstrated recently that epigenetic silencing of SOX1 gene occurs frequently in cervical cancer. However, the possible role of SOX1 in cervical cancer remains unclear. This study aimed to explore whether SOX1 functions as a TSG in cervical cancer. We established a constitutive and an inducible system that overexpressed SOX1 and monitored its function by in vitro experiments. To confirm SOX1 function, we manipulated SOX1 using an inducible expression approach in cell lines. The effect of SOX1 on tumorigenesis was also analyzed in animal models. Overexpression of SOX1 inhibited cell proliferation, anchorage independency, and invasion in vitro. SOX1 suppressed tumor growth in nonobese diabetic/severe combined immunodeficiency mice. After induction of SOX1 by doxycycline (DOX), SOX1 inhibited cell growth and invasion in the inducible system. Repression of SOX1 by withdrawal of DOX partially reversed the malignant phenotype in cervical cells. SOX1 inhibited TCF-dependent transcriptional activity and the Wnt target genes. SOX1 also repressed the invasive phenotype by regulating the expression of invasion-related genes. Taken together, these data suggest that SOX1 can function as a tumor suppressor partly by interfering with Wnt/β-catenin signaling in cervical cancer. © 2013.

The Canadian Women's HIV Study (CWHS) enrolled human immunodeficiency virus (HIV)-positive and high-risk HIV-negative women in a longitudinal cohort. This analysis considered the effects of HIV and highly active antiretroviral therapy (HAART) on HPV persistence and cervical squamous intraepithelial lesions (SILs). Longitudinal cytopathologic and HPV DNA results were analyzed using multistate models. States of cervical SIL were defined as absent, present, and treatment; HPV states were defined as negative or positive. Demographic variables and markers of sexual activity were considered predictors. Results were calculated on the basis of transition probabilities and reported as hazard ratios (HRs). The CWHS followed 750 HIV-positive and 323 HIV-negative women during 1993-2002. A total of 467 and 456 women were included in the longitudinal cervical cytopathologic and HPV DNA analyses, respectively. HIV-positive women had increased prevalence (46.6% vs 28.7%; P < .0001), increased acquisition (HR, 2.3; P = .03), and decreased clearance (HR, 0.4; P < .001) of oncogenic HPV as compared to HIV-negative women. Oncogenic HPV infection predicted progression of cervical dysplasia from normal to abnormal SIL (HR, 2.8; P = .002). Among HIV-positive participants, HAART increased the likelihood of regression (from present to absent) of cervical SIL (HR, 3.3; P = .02) and increased the clearance of oncogenic HPV types other than HPV-16 or HPV-18 (HR, 2.2; P = .01). This analysis demonstrated beneficial effects of HAART on cervical SIL in HIV-positive women.

Histological low-grade squamous intraepithelial lesion/cervical intraepithelial neoplasia grade 1 (LSIL/CIN1) preceded by normal or mildly abnormal cytology is recommended for conservative follow-up, with no separated management. In this study, we assessed the triage value of human papillomavirus (HPV) 16/18 genotyping in 273 patients with LSIL/CIN1. HPV16/18 genotyping was performed at baseline and follow-up was at 6-monthly intervals for up to 2 years. At each follow-up, women positive for cytology or high-risk HPV (hrHPV) were referred for colposcopy. Enrollment cytology, HPV16/18 genotyping, and questionnaire-obtained factors were linked to the 2-year cumulative progression rate. Univariate and multivariate analyses were performed taking into account time-to-event with Cox proportional hazard regression. The results showed that 190 cases (69.6%) regressed, 37 (13.6%) persisted, and 46 (16.8%) progressed. HPV16/18 positivity (hazard ratio (HR), 2.708; 95% confidence interval (CI), 1.432-5.121; P=0.002) is significantly associated with higher 2-year cumulative progression rate. Sub-analysis by enrollment cytology and age restricted the positive association among patients preceded by mildly abnormal cytology and aged 30 years or older. Immediate treatment is a rational recommendation for the high-risk subgroup, when good compliance is not assured.

The development and initial validation of a sensitive bedside cognitive screening test.

PubMed

Faust, D; Fogel, B S

1989-01-01

Brief bedside cognitive examinations such as the Mini-Mental State Examination are designed to detect delirium and dementia but not more subtle or delineated cognitive deficits. Formal neuropsychological evaluation provides greater sensitivity and detects a wider range of cognitive deficits but is too lengthy for efficient use at the bedside or in epidemiological studies. The authors developed the High Sensitivity Cognitive Screen (HSCS), a 20-minute interview-based test, to identify patients who show disorder on formal neuropsychological evaluation. An initial study demonstrated satisfactory test-retest and interrater reliability. The HSCS was then administered to 60 psychiatric and neurological patients with suspected cognitive deficits but without gross impairment, who also completed formal neuropsychological testing. Results of both tests were independently classified as either normal, borderline, or abnormal. The HSCS correctly classified 93% of patients across the normal-abnormal dichotomy and showed promise for characterizing the extent and severity of cognitive dysfunction.

At an HIV clinic in the Limpopo province of South Africa, chart reviews revealed long delays in addressing abnormal Pap smears, difficulty in referrals, poor quality and lost results, and increasing cases of cervical cancer. To address these barriers, a "see and treat" approach to screening was proposed. The objective was to integrate this method into current HIV care offered by local providers and to obtain demographic and risk factor data for use in future educational and intervention programs in the region. A cross sectional study of HIV farm workers and at-risk sex workers attending an HIV clinic was performed with visual inspection with acetic acid (VIA). Those with positive screens were offered cryotherapy. Clinic charts were reviewed retrospectively for Pap smear results for the previous year at the time of program initiation and at 12 and 18 months post-program. A total of 403 participants consented and underwent screening with VIA (306 Farm workers and 97 sex workers participated). 83.9% of participants (32.9% sex workers and 100% farm workers) were HIV +. VIA was positive in 30.5% of participants, necessitating cryotherapy. There was no significant difference in VIA positivity between HIV + farm workers and sex workers. There was a positive correlation between Pap smears and VIAs results. We demonstrate successful integration of cervical cancer screening using VIA for HIV + farm workers and sex workers into an existing HIV treatment and prevention clinic in rural South Africa, addressing and treating abnormal results promptly.

Compressive cervical pannus formation in a patient after 2-level disc arthroplasty: a rare complication treated with posterior instrumented fusion.

PubMed

Brophy, Carl M; Hoh, Daniel J

2018-06-01

Cervical disc arthroplasty (CDA) has received widespread attention as an alternative to anterior fusion due to its similar neurological and functional improvement, with the advantage of preservation of segmental motion. As CDA becomes more widely implemented, the potential for unexpected device-related adverse events may be identified. The authors report on a 48-year-old man who presented with progressive neurological deficits 3 years after 2-level CDA was performed. Imaging demonstrated periprosthetic osteolysis of the vertebral endplates at the CDA levels, with a heterogeneously enhancing ventral epidural mass compressing the spinal cord. Diagnostic workup for infectious and neoplastic processes was negative. The presumptive diagnosis was an inflammatory pannus formation secondary to abnormal motion at the CDA levels. Posterior cervical decompression and instrumented fusion was performed without removal of the arthroplasty devices or the ventral epidural mass. Postoperative imaging at 2 months demonstrated complete resolution of the compressive pannus, with associated improvement in clinical symptoms. Follow-up MRI at > 6 months showed no recurrence of the pannus. At 1 year postoperatively, CT scanning revealed improvement in periprosthetic osteolysis. Inflammatory pannus formation may be an unexpected complication of abnormal segmental motion after CDA. This rare etiology of an epidural mass associated with an arthroplasty device should be considered, in addition to workup for other potential infectious or neoplastic mass lesions. In symptomatic individuals, compressive pannus lesions can be effectively treated with fusion across the involved segment without removal of the device.

Background Large numbers of women who participate in cervical screening require follow-up for minor cytological abnormalities. Little is known about the psychological consequences of alternative management policies for these women. We compared, over 30-months, psychosocial outcomes of two policies: cytological surveillance (repeat cervical cytology tests in primary care) and a hospital-based colposcopy examination. Methods Women attending for a routine cytology test within the UK NHS Cervical Screening Programmes were eligible to participate. 3399 women, aged 20–59 years, with low-grade abnormal cytology, were randomised to cytological surveillance (six-monthly tests; n = 1703) or initial colposcopy with biopsies and/or subsequent treatment based on colposcopic and histological findings (n = 1696). At 12, 18, 24 and 30-months post-recruitment, women completed the Hospital Anxiety and Depression Scale (HADS). A subgroup (n = 2354) completed the Impact of Event Scale (IES) six weeks after the colposcopy episode or first surveillance cytology test. Primary outcomes were percentages over the entire follow-up period of significant depression (≥8) and significant anxiety (≥11; “30-month percentages”). Secondary outcomes were point prevalences of significant depression, significant anxiety and procedure-related distress (≥9). Outcomes were compared between arms by calculating fully-adjusted odds ratios (ORs) for initial colposcopy versus cytological surveillance. Results There was no significant difference in 30-month percentages of significant depression (OR = 0.99, 95% CI 0.80–1.21) or anxiety (OR = 0.97, 95% CI 0.81–1.16) between arms. At the six-week assessment, anxiety and distress, but not depression, were significantly less common in the initial colposcopy arm (anxiety: 7.9% vs 13.4%; OR = 0.55, 95% CI 0.38–0.81; distress: 30.6% vs 39.3%, OR = 0.67 95% CI 0.54–0.84). Neither anxiety nor depression differed between arms at subsequent time-points. Conclusions There was no difference in the longer-term psychosocial impact of management policies based on cytological surveillance or initial colposcopy. Policy-makers, clinicians, and women themselves can be reassured that neither management policy has a significantly greater psychosocial cost.

The Chiari I malformation is a congenital abnormality characterised by downward displacement of the cerebellar tonsils through the foramen magnum into the cervical spine. It presents clinically most often in young adult women. Known ocular manifestations linked to Chiari I consist primarily of oculomotor paresis with cranial nerve VI palsy and convergence/divergence abnormalities. Papilloedema is a rare manifestation of Chiari I with a clinical presentation often similar to that of idiopathic intracranial hypertension. To highlight this unusual complication, the authors report a 64-year-old female who developed papilloedema as the only presenting neurological symptom resulting from a Chiari I malformation.

Persistent infection with High Risk Human Papillomavirus (HR HPV) typesplaysamajor role in the development of cervical cancer. Therefore, the detection of HR HPV types is an essential part of cervical cancer screening. The aim of this study was to estimate the prevalence of HR HPV infection among healthy women undergoing routine cervical cancer screening in Iran. In this cross-sectional study,the results of HPV DNA typing in 2453 normal Iranian womenwhowere referred for routine cervical cancer screening from September 2015 to March 2017 were analyzed. Participants were screened using COBAS assay for HPV DNA typing and liquid based cytology. A total of 2453 healthy sexually active women were included in this study. The mean age was 35.1 ± 8.08 years. The overall prevalence of HR HPV infection was 10.3%. HPV16 was found in 73 (3%) women. The prevalence of HPV18 and other HR HPV typeswere 16(0.7%) and166 (8.2%),respectively. Approximately, 5% of the study population had an abnormal cervical cytology (ASCUS or worse), of whom 34% were infected by HR HPV. The prevalence of HR HPV infection among Iranian women has increased in the recent years which indicates the need for public education and health planning toprevent this cancer through vaccination and early diagnosis using screening tests.HPV DNA typing, diagnosisand the distribution of prevalent genotypes should be considered in the development of comprehensive cervical cancer prevention programs in Iran.

Introduction Cervical cancer is a malignancy originating in the transformation zone of the cervix, most commonly in the squamous cells. It is the fourth most common cancer in women worldwide, and the third most common cause of female cancer death. Genital human papilloma viruses (HPV) are sexually transmitted and approximately 630 milion people worldwide are infected. More than 200 genotypes, subtypes and variants have been reported, 13-15 being oncogenic type, which could be responsible for cervical intraepithelial lesions (CIN) or cancer. Aim Aim of this study was to evaluate the prevalence of this infection and to identify specific types of human papiloma virus in cervical intraepithelial lesions and cervical cancer in Macedonian women. Material and methods The study was conducted at the University Clinic for Obstetrics and Gynecology, Skopje, Macedonia, in a period of four years. The study was performed on a cohort of 1895, 18 - 73 year old patients who during primary examination had already abnormal PAP smear test. Cervical cells were collected in the lithotomy gynecological position of the patient, using endocervical cytobrush and cotton-tipped swab, and both were placed in sterile test tube with phosphate buffered saline. Samples were stored at temperature of 2 - 8 °C and Human Pappiloma Virus (HPV) genotyping was analyzed within 7 days by multiple Polymerase Chain Reaction (PCR) methods. Results The mean age of enrolled women was 40,8 years±10.36 SD(minimum of 18 and maximum 73 years. Among the patients, the presence of HPV by using PCR was detected in 40,68 % (769 patients) and was highly associated with cervical abnormalities. The prevalence of HPV was highest (82,1%) in women aged 20-years or less and it decreased with age and was lowest (19,9%) among patients older than 50 years. The prevalence of oncogenic types of the virus was higher if the cytologic diagnosis is CIN 3/Carcinoma in situ (CIS). In these patients detection of high risk HPV was in 79,1% females with CIN 3 and 97,5 % in females with CIS. The lowest prevalence was detected in patients with atypical squamous cells of undetermined significance (ASCUS) (23,9%) and CIN 1-25 (6%). Results of HPV typing show that genotypes were found either single or multiple in both single and multiple infections. We have seen that HPV 16, 18 and 31 were the most common types detected among the patients from Macedonia. HPV 16 was present even in 52,1 % of women with CIS and in 41,2% in women with CIN 3. HPV type 31 ranked second in patients wit CIN1, CIN2, CIN3 but HPV 18 ranked second in patients with CIS with (12,8%). Surprisingly, patients with mixed infection had more low grade intraepithelial squamous lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL) then CIS. Conclusion Among Macedonian women, HPV 16, 31 and 18 were HPV types strongly associated with intraepithelial cervical lesions and cervical cancers. The prevalence of high risk HPV was highest in youngest women, but the risk was highest among patients with invasive cervical cancer (ICC). Surprisingly, patients with mixed infection had more LSIL and HSIL then CIS. PMID:29416214

The author, based on up to date published dates, intends to present the classification and ethiopathogeny of the diaphragmatic hernias, except the aesophagic hiatus oms. This is an interesting chapter of the borderline surgery (abdominal and thorax). They are placed on the second position in frequency (after the hiatal hernias) in the diaphragmatic pathology; they are internal hernias, through congenital or obtained holes which allow to abdominal viscera to pass into thorax. They are--in the most cases, even elderly ones-congenital, result of the abnormalities in the embrionary growth of the diaphragm. A special place' is represented by the traumatic hernias.

The practice of breast imaging in a collaborative multidisciplinary environment adds significant value to outcomes in women's health care. In this article, we describe multidisciplinary considerations in breast cancer screening and early detection, the impact of imaging and histopathologic findings in the diagnostic evaluation and management of breast abnormalities, and the contribution of imaging to surgical and radiation therapy planning for the breast cancer patient. The multidisciplinary delivery of breast care for women that incorporates screening, diagnosis of borderline and high-risk lesions, and management of the breast cancer patient adds considerable value to outcomes in health care.

previous studies have suggested an association between systemic lupus erythematosus (SLE), abnormal cervical smears and squamous intraepithelial lesions (SIL), but the underlying cause of this association is not well defined. To review Pap smear and biopsy results in SLE women compared with healthy controls and to identify traditional risk factors associated with abnormal smears. Retrospective cohort study. Sixty-two SLE patients and 1719 controls were included. Women with abnormal Pap smear results were referred to colposcopic biopsy histology. Information on traditional risk factors was obtained. Among SLE patients, activity score (Mex-SLEDAI) and immunosuppressive drugs exposure also were determined. Fourteen (22%) out of 62 patients had abnormal Pap smear results, compared with 120 (7%) out of 1719 controls. Thirteen (92%) out of 14 patients showed SIL by histological examination, compared with 27 (22%) out of 120 controls. Two SLE women had condylomata. There were no significant differences in the use of immunosuppressive agents among SLE patients with and without SIL. Abnormal Pap smears, SIL by biopsy and changes in the sexual behavioral were more common among SLE patients than in controls. The immunosuppressive drug exposure was not associated with abnormal Pap smears.

The mechanisms that regulate papillomavirus gene expression include DNA methylation. The transcription of papillomavirus oncogenes E6 and E7 is controlled by certain regulatory elements in the LCR, which include binding sites for the E2 protein, a viral regulator of oncogene expression. In HPV-31-infected exfoliated cervical cells, the CpG methylation of the entire LCR was determined by next-generation sequencing after bisulfite modification. Six of the 22 cases had methylated CpG sites in the HPV-31 LCR, including position 7479 and/or 7485, at the promoter distal E2 binding site, thus suggesting a potential regulatory mechanism for papillomavirus transcription.

The H-reflex of the flexor carpi radialis (FCR H-reflex) has not been commonly used for the diagnosis of cervical radiculopathy when compared with the routinely tested soleus H-reflex. Although both S1 and S2 roots innervate the soleus, the H-reflex is selectively related to S1 nerve root function clinically. Flexor carpi radialis is also innervated by two nerve roots which are C6 and C7. Although they are among the most common roots involved in cervical radiculopathy, few studies reported if the attenuation of the FCR H-reflex is caused by lesions affecting C7 or C6 nerve roots, or both. We aimed to identify whether an abnormal FCR H-reflex was attributed to the C7 or C6 nerve root lesion, or both. The sensitivities of needle electromyography, FCR H-reflex, and provocative tests in unilateral C7 or C6 radiculopathy were also compared in this study. A concentric needle electrode recorded bilateral FCR H-reflexes in 41 normal subjects (control group), 51 patients with C7 radiculopathy, and 54 patients with C6 radiculopathy. Clinical, radiological, and surgical approaches identified the precise single cervical nerve root involved in all patient groups. The H-reflex and M-wave latencies were measured and compared bilaterally. Abnormal FCR H-reflex was defined as the absence of the H-reflex or a side-to-side difference over 1.5 milliseconds which was based on the normal side-to-side difference of the H-reflex latency of 16.9 milliseconds (SD = 1.7 milliseconds) from the control group. We also determined standard median and ulnar conduction and needle electromyography. The provocative tests included bilateral determination of the Shoulder Abduction and Spurling's tests in all radiculopathy group patients. Abnormal FCR H-reflexes were recorded in 45 (88.2%) of C7 radiculopathy group patients, and 2 (3.7%) of C6 radiculopathy group patients (P < 0.05). Needle electromyography was abnormal in 41 (80.4%) of C7 radiculopathy patients and 43 (79.6%) of C6 radiculopathy patients. Provocative tests were positive in 15 (29.4%) of C7 radiculopathy patients and 25 (46.3%) of C6 radiculopathy patients. Flexor carpi radialis H-Reflex provides a sensitive assessment of evaluating the C7 spinal reflex pathway. Clinically, a combination of the FCR H-reflex with needle electromyography may yield the highest level of diagnostic information for evaluating clinical cases of C7 radiculopathy.

Using a scanning near-field optical microscope coupled to an infrared free electron laser (SNOM-IR-FEL) in low-resolution transmission mode, we collected chemical data from whole cervical cells obtained from 5 pre-menopausal, non-pregnant women of reproductive age, and cytologically classified as normal or with different grades of cervical cell dyskaryosis. Imaging data are complemented by demography. All samples were collected before any treatment. Spectra were also collected using attenuated total reflection, Fourier-transform (ATR-FTIR) spectroscopy, to investigate the differences between the two techniques. Results of this pilot study suggests SNOM-IR-FEL may be able to distinguish cervical abnormalities based upon changes in the chemical profiles for each grade of dyskaryosis at designated wavelengths associated with DNA, Amide I/II, and lipids. The novel data sets are the first collected using SNOM-IR-FEL in transmission mode at the ALICE facility (UK), and obtained using whole cells as opposed to tissue sections, thus providing an 'intact' chemical profile. These data sets are suited to complementing future work on image analysis, and/or applying the newly developed algorithm to other datasets collected using the SNOM-IR-FEL approach.

Lymph node enlargement may be an incidental finding on examination, or may be associated with a patient complaint. It is likely that over half of all patients examined each day may have enlarged lymph nodes in the head and neck region. There are no written guidelines specifying when further evaluation of lymphadenopathy is necessary. With such a high frequency of occurrence, oral health care providers need to be able to determine when lymphadenopathy should be investigated further. Although most cervical lymphadenopathy is the result of a benign infectious etiology, clinicians should search for a precipitating cause and examine other nodal locations to exclude generalized lymphadenopathy. Lymph nodes larger than 1 cm in diameter are generally considered abnormal. Malignancy should be considered when palpable lymph nodes are identified in the supraclavicular region, or when nodes are rock hard, rubbery, or fixed in consistency. Patients with unexplained localized cervical lymphadenopathy presenting with a benign clinical picture should be observed for a 2- to 4-week period. Generalized lymphadenopathy should prompt further clinical investigation. This article reviews common causes of lymphadenopathy, and presents a methodical clinical approach to a patient with cervical lymphadenopathy.

Human Papilloma Virus (HPV) infection is the major cause of cervical cancer worldwide. With limited data available on HPV prevalence in the Arab countries, this study aimed to identify the prevalence and genotypic distribution of HPV in the State of Qatar. 3008 cervical samples, exclusively of women with Arabic origin residing in Qatar were collected from the Women's Hospital and Primary Health Care Corporation in Doha, State of Qatar. HPV DNA detection was done using GP5+/6+ primers based real time-polymerase chain reaction (RT-PCR) assay followed by the usage of HPV type specific primers based RT- PCR reactions and Sanger sequencing for genotype identification. Similar prevalence rates of HPV infection was identified in both Qatari and non-Qatari women at 6.2% and 5.9% respectively. HPV prevalence rate of 5.8% and 18.4% was identified in women with normal cytology and in women with abnormal cytology respectively. HPV 81, 11 and 16, in decreasing order were the most commonly identified genotypes. HPV 81 was the most frequent low-risk genotype among women with both normal (74.0%) and abnormal (33.3%) cytology. HPV 16 (4.6%) was identified as the predominant high-risk HPV genotype among women with normal cytology and HPV 16, HPV 18, and HPV 56 (22.2% each) were the most common identified high-risk genotypes in women with abnormal cytology. The overall HPV prevalence in Arab women in Qatar was identified as 6.1% with an increased HPV prevalence seen in women with abnormal cytology results and no significant trends seen with age. In contrast to Western countries, we report a varied genotypic profile of HPV with a high prevalence of low-risk HPV genotype 81 among the Arab women residing in Qatar.

Spine deformities in rare congenital syndromes: clinical issues.

Campbell, Robert M

2009-08-01

A focused review of the literature with regard to the important system abnormalities of patients with spinal deformities associated with exotic congenital syndromes with additional data from the author's own experience in assessment of patients with rare syndromes treated for thoracic insufficiency syndrome. The objectives of this study are to emphasize important medical considerations that influence the choice of surgical treatment of spinal deformity in patients with exotic congenital syndromes and point out preoperative strategies that reduce treatment morbidity and mortality of these patients. Individual experience is limited in the treatment of spine abnormality in rare exotic syndromes and the medical aspects of these syndromes that may impact spinal treatment are seldom discussed in detail in the orthopedic literature. For a successful outcome in the treatment of spinal deformity in these unique patients, a working knowledge of the unique pitfalls in their medical care is necessary in order to avoid morbidity and mortality during their treatment. The literature was reviewed for 6 exotic congenital syndromes with known or unreported spinal abnormalities and the author's personal 22-years experience of the treatment of thoracic insufficiency syndrome in the relevant congenital syndromes was summarized. Children with Marfan syndrome and spinal deformity may have serious cardiac abnormalities. Spontaneous dissection of the aortic root is a clear danger and patients should be monitored by serial echocardiograms. Prophylactic cardiac surgery may be necessary before spinal surgery is to be performed. Patients with Jeune syndrome have a high rate of proximal cervical stenosis and should undergo screening with cervical spine films at birth. Significant stenosis or instability may require decompression and cervical-occipital fusion. Arthrogryposis may be associated with a severe scoliosis and jaw contracture may make intubation difficult. Larsen syndrome may have early onset scoliosis that is very rigid and requires early intervention. Cervical kyphosis and subluxation may be lethal in these patients and screening radiographs are important. Upper airway abnormalities are an anesthesia concern. Jarcho-Levin syndrome is a thoracic volume depletion deformity due to shortness of the thorax, either a spondylocostal dysostosis variant or spondylothoracic dysplasia. The former has a chaotic congenital scoliosis with varied combination of missing and fused ribs. Although spondylocostal dysostosis has a benign reputation in the literature for respiratory complications, respiratory insufficiency is nevertheless common and 1 death is known from respiratory failure. Spondylothoracic dysplasia seldom has significant scoliosis, but has a mortality rate approaching 50% from respiratory complications due to thoracic insufficiency syndrome. In spite of severe restrictive respiratory disease, adult survivors of spondylothoracic dysplasia appear to do well clinically for unknown reasons. Cerebrocostomandibular syndrome has scoliosis, micrognathia, and thoracic insufficiency syndrome, due to an "implosion" deformity of the thorax from congenital pseudarthrosis of the posterior ribs. For optimal patient care, it is necessary to have a clear understanding of exotic congenital syndromes and how they may impact on both the presentation of spinal deformity and the response to treatment, as well as how they may introduce additional morbidity into standard treatment plans. It is clear that with this understanding that preoperative strategies can be employed to enhance the safety of spinal treatment for these unique children.

To determine whether the number of cigarettes smoked per day and years of smoking were risk factors for preinvasive and invasive cervical lesions in Venezuelan female sex workers. The clinical history of 438 female sex workers (FSWs) was taken and each received a gynecological examination, a Pap smear, and a colposcopic examination. A colposcopically-guided cervical biopsy was taken when the epithelium appeared abnormal. The FSWs' mean age was 32.16+/-8 years. Age at first sexual intercourse was 15.9+/-2 years, parity was 4.1+/-2.3, live births were 3+/-3, and age at first delivery was 16.6+/-4.7 years. Cervical biopsies were performed in 84 FSWs. Sixty-four of them (76.2%) had preinvasive or invasive lesions and 47 (73.4%) were current smokers (Relative Risk) (RR), 1.26; 95% confidence interval (CI), 1.02-1.55; P<0.03]. FSWs who smoked more than 20 cigarettes per day had an increased RR to get a premalignant or malignant cervical lesion (RR, 1.27; 95% CI, 1.02-1.52; P<0.03). There was no statistically significant difference between FSWs who smoked 20 cigarettes or more per day and FSWs who smoked less than 20 cigarettes per day (RR, 1.36; 95% CI, 0.81-2.29; P<0.25). FSWs who had been smoking for 5 years or more were at risk to develop preinvasive or invasive cervical lesions (RR, 1.37; 95% CI, 1.01-1.86; P<0.04). The risk for FSWs to develop preinvasive or invasive cervical lesions increased with the number of cigarettes they smoked per day and their years of smoking.

Genotype distribution of human papillomavirus (HPV) in histological sections of cervical intraepithelial neoplasia and invasive cervical carcinoma in Madrid, Spain

PubMed Central

2012-01-01

Background Human Papillomavirus (HPV) genotype distribution and co-infection occurrence was studied in cervical specimens from the city of Madrid (Spain), as a contribution to the knowledge of Human Papillomavirus genotype distribution and prevalence of carcinogenic HPV types in cervical lesions in Spain. Methods A total of 533 abnormal specimens, from the Hospital General Universitario “Gregorio Marañón” of Madrid, were studied. These included 19 benign lesions, 349 cervical intraepithelial neoplasias 1 (CIN1), 158 CIN2-3 and 7 invasive cervical carcinomas (ICC). HPV genotyping was performed using PCR and tube array hybridization. Results We detected 20 different HPV types: 13 carcinogenic high-risk HPV types (HR-HPVs), 2 probably carcinogenic high-risk HPV types (PHR-HPVs) and 5 carcinogenic low-risk HPV types (LR-HPVs). The most frequent HPV genotypes found in all specimens were HPV16 (26.0%), 31 (10.7%) and 58 (8.0%). HPV 18 was only detected in 5.0%. Co-infections were found in 30.7% of CIN 1 and 18.4% cases of CIN2-3. The highest percentage of HR HPVs was found in those specimens with a CIN2-3 lesion (93.7%). Conclusion As our study shows the current tetravalent vaccine could be effective in our geographical area for preventing all the invasive cervical carcinomas. In addition, upon the estimates of the important presence of other HR-HPV types – such as 31, 58, 33 and 52 – in different preneoplasic lesions the effectiveness of HPV vaccination in our geographical area, and others with similar genotype distribution, should be limited.

Gait abnormalities have been seen in patients with Parkinson disease or Parkinson-like (P-L) disorders and cervical spinal stenosis. Acute presentation of P-L symptoms has been reported in 24 cases caused by chronic subdural hematomas with 11 cases due to bilateral chronic subdural hematomas. When a patient also presents with cervical spinal stenosis, the correct therapeutic decision between P-L disorders and myelopathy is challenging. An 80-year-old male presented with a 2-week history of weakness in his left leg. A few days before presentation, his gait had deteriorated quite dramatically. Neurologic examination showed mild leg weakness, hyperreflexia, and a gait that was slow and wide based, at times festinating but with relatively spared arm movement. He also had masked facial features with increased tone in his extremities. Magnetic resonance imaging of the cervical spine showed cervical stenosis at C5-6, and computed tomography of the head showed large bilateral subdural hematomas. The subdural hematomas were drained. Immediate improvement in his symptoms was observed with complete resolution by his third month of follow-up. The patient never had a history of Parkinson disease. This paper reports for the first time a patient who presented with acute P-L symptoms and cervical myelopathy with findings of both bilateral chronic subdural hematomas and cervical spinal stenosis. The decision to drain the subdural hematoma in our case resulted in full recovery of the patient's gait and other extrapyramidal symptoms. This paper reviews the literature on reversible P-L symptoms caused by bilateral chronic subdural hematomas. Copyright © 2017 Elsevier Inc. All rights reserved.

Background Diagnosis may be delayed in young females with cervical cancer because of a failure to recognise symptoms. Aim To examine the extent and determinants of delays in diagnosis of young females with symptomatic cervical cancer. Design and setting A national descriptive study of time from symptoms to diagnosis of cervical cancer and risk factors for delay in diagnosis at all hospitals diagnosing cervical cancer in England. Method One-hundred and twenty-eight patients <30 years with a recent diagnosis of cervical cancer were interviewed. Patient delay was defined as ≥3 months from symptom onset to first presentation and provider delay as ≥ 3 months from first presentation to diagnosis. Results Forty (31%) patients had presented symptomatically: 11 (28%) delayed presentation. Patient delay was more common in patients <25 than patients aged 25–29 (40% versus 15%, P = 0.16). Vaginal discharge was more common among patients who delayed presentation than those who did not; many reported not recognising this as a possible cancer symptom. Provider delay was reported by 24/40 (60%); in some no report was found in primary care records of a visual inspection of the cervix and some did not re-attend after the first presentation for several months. Gynaecological symptoms were common (84%) among patients who presented via screening. Conclusions Young females with cervical cancer frequently delay presentation, and not recognising symptoms as serious may increase the risk of delay. Delay in diagnosis after first presentation is also common. There is some evidence that UK guidelines for managing young females with abnormal bleeding are not being followed. PMID:25267045

The incidence of cervical disc herniation is estimated about 5.5/100,000, and they lead to surgical intervention in 26 %. Cervical disc herniation causes radiculopathy, which defines by radicular pain and sensory deficit and maybe weakness following the path of the affected nerves. Classically, cervical radiculopathy is expected to follow its specific dermatome-C4, C5, C6, C7 and C8. We investigate patients who present with discrepancy between classical radiculopathy and imaging findings in the daily practice of our profession. We reviewed the medical records of 102 patients with cervical radiculopathy, caused by cervical disc herniation. All patients had surgery. We found an apparent discrepancy between clinical and radiological findings, patients complained of radiculopathy on one side, and magnetic resonance imaging (MRI) scan or CT scan finding on the other side in ten patients (10.2 %). We did not found any other abnormalities in preoperative and post-operative period. All patients underwent cervical diskectomy via anterior approach. Six weeks after surgery eight patients (80 %) recovered completely, and 3 months after all ten patients (100 %) had been relieved totally. The aim of this paper is review of this medical concept and management of radiculopathy in patients with this discrepancy. As far as we know, the subject has not yet been touched in this light in medical literature. The discrepancy between clinical radiculopathy and disc herniation level on MRI or on CT scan is not rare. Management of this discrepancy requires further investigation to avoid missing diagnosis and treatment failure.

to carry out a situational analysis of cervical cancer prevention activities in Argentina, specifically regarding (a) the organizational framework of cervical cancer prevention activities; (b) Pap-smear coverage; (c) cytology laboratory organization; and (d) follow-up/treatment of women with abnormal lesions. a situational analysis of provincial cervical cancer programs using data from an ad-hoc questionnaire sent to the leaders of cervical cancer prevention programs in Argentina's 24 provinces. In addition, the provinces' program guidelines, statistical reports, laws, and program regulations were reviewed and certain key leaders were personally interviewed. data were obtained for 19 of Argentina's 24 provinces. Four of the 19 provinces had no formal program framework. Conventional cytology was the most commonly used screening test. Screening was mainly opportunistic. The recommended interval between normal tests was 3 years in most provinces. The eligible age for screening ranged from 10-70 years of age; however, annual or biannual screening was the usual practice after becoming sexually active. None of the provincial programs had data available regarding Pap-smear coverage. Most of the cytology laboratories did not have a quality control policy. The number of smears read varied greatly by laboratory (650-24 000 per year). A log of events related to screening and treatment did not exist in most provinces. screening in Argentina is mainly opportunistic, characterized by an estimated low coverage, coexisting with over-screening of women with access to health services, and an absence of quality control procedures. Policies for cervical cancer screening in the provinces vary and, most often, deviate from the national recommendation of one Pap smear every 3 years for women 35-64 years of age. Ensuring compliance with national program guidelines is an essential step toward significantly reducing the burden of cervical cancer.

Developing countries often lack the necessary resources to use the Papanicolaou (Pap) smear as a screening tool for cervical abnormalities. Because the burden of cervical cancer is highest in such low-resource settings, alternative techniques have been sought. Recently, interest in visual inspection with acetic acid (VIA) has increased. Numerous studies have been conducted on its accuracy and its ability to detect cervical lesions when compared with other techniques, both conventional and nonconventional. This review summarizes key findings from the literature to provide researchers and policymakers with an up-to-date summary on VIA. PubMed was used to identify relevant journal articles published between 1982 and 2002. Key words were cervical cancer screening, visual inspection, VIA (visual inspection with acetic acid), DVI (direct visual inspection), AAT (acetic acid test), and cervicoscopy. Studies were eligible for review only if they involved analysis of primary VIA data (ie, not review articles); studies involving magnification devices were excluded. Fifteen studies were reviewed in total; key results were extracted and a summary analysis was performed for sensitivity and specificity parameters. When reported, sensitivity ranged between 66% and 96% and specificity between 64% and 98%. Authors comparing VIA with cytology noted that the overall usefulness of VIA compares favorably with that of the Pap test. The reported findings reviewed here suggest that VIA has the potential to be a cervical cancer screening tool, especially in low resource settings. Obstetricians & Gynecologists, Family Physicians. After completion of this article, the reader will be able to describe how visual inspection of the cervix for cervical cancer screening (VIA) is performed, to summarize the current literature on VIA, and to list potential advantages of VIA.

The purpose of this investigation was to evaluate the impact of the vaginal milieu on the presence of abnormal Pap smears and a positive human papilloma virus (HPV) test. A cross-sectional study was conducted between June 2014 and May 2015, evaluating the vaginal discharge by fresh wet mount microscopy and comparing these data with Pap smear findings. Wet mount slides were scored for bacterial vaginosis (BV), aerobic vaginitis (AV), presence of Candida and Trichomonas vaginalis. Cytologic evaluation was done on all Pap smears according to the Bethesda criteria. The cobas© HPV Test (Roche) was performed for HPV detection. A total of 622 cases were evaluated. The mean age of the patients was 41.6 ± 10.65 years (range 21-75). Eighty-three women (13.3 %) had a cytology result worse than low-grade squamous intraepithelial lesion (LSIL). When comparing this group with the one with normal or minor [atypical squamous cells of undetermined significance (ASC-US) or LSIL] Pap smear abnormalities, there were no differences in the presence of Candida (32.5 % vs. 33.2 %, p = 1.0), absence of lactobacilli (38.6 % vs. 32.5 %, p = 0.32) or BV (20.5 % vs. 13.2 %, p = 0.09). On the other hand, moderate or severe inflammation (msI) (41.0 % vs. 28.8 %, p = 0,04), moderate or severe AV (msAV) (16.9 % vs. 7.2 %, p = 0.009) and msAV/BV (37.3 % vs. 20.0 %, p = 0.001) were more common in women with such major cervical abnormalities. No significant association was found between deviations of the vaginal milieu and high-risk HPV infection. The presence of msI or msAV, but not BV, is independently associated with an increased risk of major cervical cytological abnormalities, but not with HPV infection.

Cervical cancer is an important health issue in Latin America. Although HPV infections can have spontaneous clearance, persistence of high-risk (HR) HPV is a risk factor for cervical cancer among women and it is even higher in HIV-infected women. To determine the prevalence of HR-HPV and risk factors among HIV-infected women attending reference services for HIV/AIDS in different regions of Brazil. Cross-sectional study conducted among HIV-infected women attended at referral care centers for HIV/AIDS in nine states of Brazil. Women from 18 to 49 years that accept to participate and were not pregnant at the time of the approach were recruited for the study. The HPV screening was realized using qPCR in closed system, in vitro Diagnostic, COBAS ® -HPV Roche. The cytology results were available by the Bethesda System. A total of 802(89.1%) from the selected women agreed to participate in the study. Median age was 39(Inter quartile range [IQR34-46]) years and median education was 9(IQR6-11) years. General prevalence of HR-HPV was 28.4%(228/802). HPV-16 prevalence rate was 8.1%(65/802), HPV-18 was 3.7%(30/802) and other types of HR-HPV were 23.6% (189/802). Risk factors for HR-HPV infection in the multivariate logistic regression analysis were: age ranging from 18 to 34 years (OR = 1.43[95%CI:1.18-1.75]), illicit drugs use (OR = 1.61[95%CI:1.10-2.42]) and abnormal cervical cytology (OR = 1.56[95%CI:1.34-1.81]). Results showed a prevalence rate of 28.4% of HR-HPV infection in women living with HIV in Brazil. These infections were significantly associated with having less than 35 years old, illicit drug use and abnormal cervical cytology. © 2017 Wiley Periodicals, Inc.

Objective To compare the accuracy of liquid based cytology using the computerised ThinPrep Imager with that of manually read conventional cytology. Design Prospective study. Setting Pathology laboratory in Sydney, Australia. Participants 55 164 split sample pairs (liquid based sample collected after conventional sample from one collection) from consecutive samples of women choosing both types of cytology and whose specimens were examined between August 2004 and June 2005. Main outcome measures Primary outcome was accuracy of slides for detecting squamous lesions. Secondary outcomes were rate of unsatisfactory slides, distribution of squamous cytological classifications, and accuracy of detecting glandular lesions. Results Fewer unsatisfactory slides were found for imager read cytology than for conventional cytology (1.8% v 3.1%; P<0.001). More slides were classified as abnormal by imager read cytology (7.4% v 6.0% overall and 2.8% v 2.2% for cervical intraepithelial neoplasia of grade 1 or higher). Among 550 patients in whom imager read cytology was cervical intraepithelial neoplasia grade 1 or higher and conventional cytology was less severe than grade 1, 133 of 380 biopsy samples taken were high grade histology. Among 294 patients in whom imager read cytology was less severe than cervical intraepithelial neoplasia grade 1 and conventional cytology was grade 1 or higher, 62 of 210 biopsy samples taken were high grade histology. Imager read cytology therefore detected 71 more cases of high grade histology than did conventional cytology, resulting from 170 more biopsies. Similar results were found when one pathologist reread the slides, masked to cytology results. Conclusion The ThinPrep Imager detects 1.29 more cases of histological high grade squamous disease per 1000 women screened than conventional cytology, with cervical intraepithelial neoplasia grade 1 as the threshold for referral to colposcopy. More imager read slides than conventional slides were satisfactory for examination and more contained low grade cytological abnormalities. PMID:17604301

Abnormal parturition, e.g. pre- or post-term birth, is associated with maternal and neonatal morbidity and increased economic burden. This could potentially be prevented by accurate detection of abnormal softening of the uterine cervix. Shear wave elasticity imaging (SWEI) techniques that quantify tissue softness, such as shear wave speed (SWS) measurement, are promising for evaluation of the cervix. Still, interpretation of results can be complicated by biological variability (i.e. spatial variations of cervix stiffness, parity), as well as by experimental factors (i.e. type of transducer, posture during scanning). Here we investigated the ability of SWEI to detect cervical softening, as well as sources of SWS variability that can affect this task, in the pregnant and nonpregnant Rhesus macaque. Specifically, we evaluated SWS differences when imaging the cervix transabdominally with a typical linear array abdominal transducer, and transrectally with a prototype intracavitary linear array transducer. Linear mixed effects (LME) models were used to model SWS as a function of menstrual cycle day (in nonpregnant animals) and gestational age (in pregnant animals). Other variables included parity, shear wave direction, and cervix side (anterior versus posterior). In the nonpregnant cervix, the LME model indicated that SWS increased by 2% (95% confidence interval 0–3%) per day, starting eight days before menstruation. During pregnancy, SWS significantly decreased at a rate of 6% (95% CI 5–7%) per week (intracavitary approach) and 3% (95% CI 2–4%) per week (transabdominal approach), and interactions between the scanning approach and other fixed effects were also significant. These results suggest that, while absolute SWS values are influenced by factors such as scanning approach and SWEI implementation, these sources of variability do not compromise the sensitivity of SWEI to cervical softening. Our results also highlight the importance of standardizing SWEI approaches to improve their accuracy for cervical assessment.

Determine the MRI characteristics of large post-traumatic cervical spine extra-arachnoid collections managed conservatively in clinically stable patients and whether evidence of clinical or imaging deterioration materialized. Following IRB approval, we conducted a retrospective search for all patients (>16 years old) over a 17-months period who had an extra-arachnoid fluid collection reported on a post-traumatic cervical spine MRI. Patients were excluded if they had surgery for an unstable fracture (n = 21), emergent decompression (n = 1) or lacked a follow-up MRI within 15 days (n = 1). Two MSK radiologists recorded the size, morphology and MRI signal characteristics of the collections. Eight patients (5 male, 3 female) met the inclusion criteria (mean age 40 years; range 19-78 years). Seven of the eight patients had fluid collections that demonstrated thin, tapered margins, extended >7 vertebral bodies and involved >180 degrees of the spinal canal. The signal characteristics of these collections varied: hyper-T1/iso-T2 (n = 1), iso-T1/T2 (n = 3), hyper-T1/hypo-T2 (n = 3) and mixed-T1/T2 (n = 1). Six of seven collections were ventral. Follow-up MRI demonstrated resolution/significant decrease in size (n = 4 between 1 and 12 days) or no change/slight decrease in size (n = 3; between 2 and 11 days). None of the seven fluid collections enlarged, no patient had abnormal cord signal, and no patient's neurologic symptoms worsened. One of eight patients had a dorsal "mass-like" collection that was slightly smaller 9 days later. In stable patients with large, tapered post-traumatic cervical spine extra-arachnoid collections managed non-surgically, none developed (1) clinical worsening, (2) abnormal cord signal or (3) collection enlargement, regardless of the collection's signal characteristics.

The objective of this study is to estimate the risk of preterm birth in patients with an ultrasound or physical exam indicated cervical cerclage based on the results of fetal fibronectin (fFN) and cervical length (CL) screening. Retrospective cohort of patients with a singleton pregnancy and an ultrasound or physical exam indicated Shirodkar cerclage placed by one maternal-fetal medicine practice from November 2005 to January 2015. Patients routinely underwent serial CL and fFN testing from 22 to 32 weeks. Based on ROC curve analysis, a short CL was defined as ≤15 mm. All fFN and CL results included are from after the cerclage placement. One hundred and four patients were included. Seventy eight (75%) patients had an ultrasound-indicated cerclage and 26 (25%) patients had a physical exam-indicated cerclage. A positive fFN was associate with preterm birth <32 weeks (15.6% versus 4.2%, p = 0.043),  <35 weeks (37.5% versus 11.1%, p = 0.002),  <37 weeks (65.6% versus 20.8%, p < 0.001), and earlier gestational ages at delivery (35.2 ± 3.9 versus 37.4 ± 2.9, p = 0.001). A short CL was also associated with preterm birth <35 weeks (50.0% versus 11.9%, p < 0.01), preterm birth <37 weeks (55.0% versus 29.8%, p = 0.033), and earlier gestational ages at delivery (34.8 ± 4.1 versus 37.2 ± 3.0, p = 0.004). The risk of preterm birth <32,  <35, and <37 weeks increased significantly with the number of abnormal markers. In patients with an ultrasound or physical exam indicated cerclage, a positive fFN and a short CL are both associated with preterm birth. The risk of preterm birth increases with the number of abnormal biomarkers.

Evidence-based clinical guidelines ensure best practice protocols are available in health care. There is a widespread use of human papillomavirus deoxyribonucleic acid (HPV-DNA) tests in Brazil, regardless of the lack of official guidelines. On behalf of the Brazilian Association for the Lower Genital Tract Pathology and Colposcopy (ABPTGIC, in the Portuguese acronym), a team of reviewers searched for published evidence and developed a set of recommendations for the use of HPV-DNA tests in cervical cancer screening in Brazil. The product of this process was debated and consensus was sought by the participants. One concern of the authors was the inclusion of these tests in the assessment of women with cytologic atypia and women treated for cervical intraepithelial neoplasia (CIN). Testing for HPV is recommended in an organized screening scenario to identify women with precursor lesions or asymptomatic cervical cancer older than 30 years of age, and it can be performed every 5 years. It also has value after the cytology showing atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSILs) as a triage test for colposcopy, in the investigation of other cytological alterations when no abnormal findings are observed at colposcopy, seeking to exclude disease, or, further, after treatment of high-grade cervical intraepithelial neoplasia, to rule out residual disease.

Stereotactic body radiation therapy (SBRT) administered via a helical tomotherapy (HT) system is an effective modality for treating lung cancer and metastatic liver tumors. Whether SBRT delivered via HT is a feasible alternative to brachytherapy in treatment of locally advanced cervical cancer in patients with unusual anatomic configurations of the uterus has never been studied. A 46-year-old woman presented with an 8-month history of abnormal vaginal bleeding. Biopsy revealed squamous cell carcinoma of the cervix. Magnetic resonance imaging (MRI) showed a cervical tumor with direct invasion of the right parametrium, bilateral hydronephrosis, and multiple uterine myomas. International Federation of Gynecology and Obstetrics (FIGO) stage IIIB cervical cancer was diagnosed. Concurrent chemoradiation therapy (CCRT) followed by SBRT delivered via HT was administered instead of brachytherapy because of the presence of multiple uterine myomas with bleeding tendency. Total abdominal hysterectomy was performed after 6 weeks of treatment because of the presence of multiple uterine myomas. Neither pelvic MRI nor results of histopathologic examination at X-month follow-up showed evidence of tumor recurrence. Only grade 1 nausea and vomiting during treatment were noted. Lower gastrointestinal bleeding was noted at 14-month follow-up. No fistula formation and no evidence of haematological, gastrointestinal or genitourinary toxicities were noted on the most recent follow-up. CCRT followed by SBRT appears to be an effective and safe modality for treatment of cervical cancer. Larger-scale studies are warranted.

Heparanase (HPA) is an enzyme that plays an important role in cancer metastasis and angiogenesis and is a potential target for molecular treatment of tumors. We previously found that abnormally high HPA expression in cervical cancer tissues is associated with poor survival and increased lymph node metastasis. The present study was conducted to assess the utility of inhibiting HPA enzyme activity in cervical cancer treatment. Two series of 13 novel HPA inhibitors were synthesized and optimized. All tested inhibitors reduced HPA enzyme activity (IC50 values ranged from 4.47 μM to 47.19 μM) and inhibited the growth of HeLa cells (IC50 values ranged from 48.16 μM to 96.64 μM). The No. 16 inhibitor inhibited the migration and growth of HeLa and Siha cells in a dose- and time-dependent manner, and increased cell apoptosis and cell cycle G0/G1 and G2/M phase arrest, while decreasing the S phase cell population. More importantly, No. 16 sensitized cervical cancer cells to low concentrations of nedaplatin, decreased HPA, c-Myc and h-TERT levels, and increased p53 levels in HeLa and Siha cells. These results suggest that this HPA inhibitor reduced proliferation and HPA expression in cervical cancer cells by restoring p53 activity and downregulating h-TERT and c-Myc expression.

To investigate whether distinct sensory phenotypes were identifiable in individuals with nonspecific arm pain (NSAP) and whether these differed from those in people with cervical radiculopathy. A secondary question considered whether the frequency of features of neuropathic pain, kinesiophobia, high pain ratings, hyperalgesia, and allodynia differed according to subgroups of sensory phenotypes. Cross-sectional study. Higher education institution. Forty office workers with NSAP, 17 people with cervical radiculopathy, and 40 age- and sex-matched healthy controls (N=97). Not applicable. Participants were assessed using quantitative sensory testing (QST) comprising thermal and vibration detection thresholds and thermal and pressure pain thresholds; clinical examination; and relevant questionnaires. Sensory phenotypes were identified for each individual in the patient groups using z-score transformation of the QST data. Individuals with NSAP and cervical radiculopathy present with a spectrum of sensory abnormalities; a dominant sensory phenotype was not identifiable in individuals with NSAP. No distinct pattern between clinical features and questionnaire results across sensory phenotypes was identified in either group. When considering sensory phenotypes, neither individuals with NSAP nor individuals with cervical radiculopathy should be considered homogeneous. Therefore, people with either condition may warrant different intervention approaches according to their individual sensory phenotype. Issues relating to the clinical identification of sensory hypersensitivity and the validity of QST are highlighted. Copyright © 2015 American Congress of Rehabilitation Medicine.

The role of human papillomavirus in screening for cervical cancer.

To review the options for effectively screening for cervical cancer, including human papilloma virus (HPV) identification, cytologic screening, colposcopy, or a combination approach. Current pathophysiology, diagnostic criteria, treatment approaches, and patient preparation and education related to cervical cancer screening and prevention are also included. Comprehensive review of current literature, including research and review articles. Because the Papanicolau (Pap) smear is a screening tool, not a diagnostic tool, further studies must be done to identify the actual nature of discovered abnormalities. Of particular concern is the classification of atypical squamous cells of undetermined significance (ASCUS), which may simply indicate inflammation, or may be the first indicator of serious pathology. Following ASCUS Pap smears with HPV screening will allow for a clarification of the best approach to treatment. A screening algorithm supported by a review of the literature is proposed. Cervical cancer is a preventable disease caused by certain forms of HPV. Current screening protocols are based on the use of the Pap smear; and in areas where this test is routine and available, morbidity and mortality rates have dropped dramatically. Many women throughout the world and in underserved regions of the U. S. do not have adequate access to routine screening with Pap smear technology. As long as women continue to die needlessly of cervical cancer, more comprehensive and accessible screening methods must be explored. (Cutting the unnecessary worldwide and in the U. S.).
