  1. Analysis of cervical smears in a Muslim population

    International Nuclear Information System (INIS)

    Screening for the cancer of the cervix remains a neglected health care issue in Pakistan. To provide baseline data for future efforts to improve screening, we conducted a retrospective analysis of cervical smears taken in the obstetrics and gynaecological clinics of the Agha Khan University Hospital, Karachi, Pakistan. We collected data on cervical smear cytology for cervical smears taken from January 1, 1990 to December 31, 1996. We assessed risk factors for dysplasia, including age, age at first marriage, and number of pregnancies. The overall prevalence of abnormal smears in our study was 0.5%. Of 20,995 cervical smears, showed non-specific inflammation, 7302 (34.8%) were reported as normal, 809 (3.85%) showed monillial infection, 148 (0.71%) showed atypia, 105 (0.5%) had dyplastic cytology and 52 (0.25%) samples were inadequate. The highest incidence of dysplastic smears was seen in the age group 35 to 44 years. Of 105 patients with dysplasia 12 were pregnant, and all were asymptomatic. The low prevalence of abnormal smears, compared with the data from Western populations, could be due to the internet bias of health awareness in the women who attended our hospital. The results of this study may serve as baseline for for future comparisons. A large community-based study may establish the exact prevalence of malignant and premalignant lesions so as to plan for future screening. (author)

    Full Text Available Abstract In a case-control study among 2064 South African women to investigate the risk of clinically invasive cancer of the cervix, we found a marked reduction in the risk of cervical cancer among women who gave a history of ever having undergone even a single Pap smear, and a statistically significant decline in the HPV positivity rate correlated with the lifetime number of Pap smears received. HPV infections and their associated low-grade lesions commonly regress, indicating that most often there is an effective host immune response against HPV infection. We hypothesized that act of performing a Pap smear is associated with inflammatory responses at the site of trauma, the cervix, and that this inflammatory signalling may be an immunological factor initiating these productive anti-HPV responses. In the present study, a randomized controlled trial, we enrolled 80 healthy young women to investigate the impact of performing a Pap smear on cervical inflammation. Forty one women, in the intervention group, received a Pap smear at enrollment and cervicovaginal lavages (CVLs were collected at baseline and 2 weeks later. Thirty nine women received no intervention at enrollment (control group but CVLs were collected at enrolment and 2 weeks later. We assessed various markers of inflammation including IL-12 p70, TNF-α, IL-8, IL-6, IL-10, and IL-1β in CVL specimens. While CVL levels of IL-8, IL-1β and IL-6 remained unchanged following a Pap smear, markers of cell mediated immunity (IL-12 p70 and TNF-α and T cell regulation (IL-10 were significantly elevated.

    Cervical cancer is the second most common female malignancy in Malaysia. Despite advances in treatment, the overall survival for this disease has not changed in the last decade. Infection by certain types of HPV is recognized as a causal and necessary factor for its development. This study was carried out to determine the prevalence of HPV infection in abnormal cervical smears in Malaysian patients using archival cervical smears retrieved from the Cytopathology Unit, Universiti Kebangsaan Malaysia Medical Centre (UKMMC) between the years 1992-1995. DNA was extracted from 38 abnormal smears comprising 25 intraepithelial lesions and 13 cervical carcinomas and 10 normal smears. Amplification of HPV genes was carried out using the polymerase chain reaction (PCR) technique. HPV genotypes were determined using direct sequencing and the results were compared to the database from Genebank. DNA was successfully extracted from all 48 cervical smears. High-risk HPV (HR-HPV) genotypes were detected in 95% of the abnormal smears. Eight high-risk oncogenic types were identified: 16, 18, 31, 51, 52, 56, 58 and 66. All (100%) cervical cancer smears showed presence of HR-HPV compared to 92% of the cervical intraepithelial lesions. Among the eight HR-HPV genotypes identified, HPV 16 and 52 were the commonest (23.7% each) HPV genotypes encountered and among the CIN lesions, HPV 16 (28%) was the most frequent. We conclude that HPV 16 is the most prevalent HPV genotype present in abnormal cervical smears in Malaysian patients, and that the use of archival material to assess the presence of HPV is potentially worthwhile, and can be utilized for longitudinal studies of HPV presence and persistence.

    OBJECTIVE--To determine the proportion of women with mild or moderate dyskaryosis in cervical smears who (a) progress to cervical intraepithelial neoplasia grade III or worse or (b) regress. DESIGN--Four and a half year cytological follow up study of women with mild or moderate dyskaryosis in cervical smears. SETTING--666 Women (mean age 28 (SD 8) years; range 14-74) found to have borderline, mild, or moderate dyskaryosis on routine screening. RESULTS--45 Women (6.8%) had a cone biopsy recommended on the basis of an abnormal follow up smear (severe dyskaryosis suggestive of cervical intraepithelial neoplasia grade III or invasive cancer), and in one patient cervical intraepithelial neoplasia grade III was reported in a biopsy specimen after dilatation and curettage. Life table analysis gave a 14% probability of a patient being recommended for a biopsy after four and a half years of follow up (95% confidence interval 12% to 15%). There was a significant excess incidence of invasive cancer of the cervix in the series compared with the general population (five cases observed compared with less than 0.1 expected). 157 Patients (24%) showed reversion to a normal cell pattern sustained in several smears over more than 18 months but a single negative smear was an unreliable indicator of apparent regression. Having two successive smears showing mild dyskaryosis or a smear at any time showing moderate dyskaryosis was a significant predictor of a subsequent severely dyskaryotic smear. CONCLUSIONS--Women found to have mild or moderate dyskaryosis in cervical smears should be kept under regular surveillance. The optimum management of these patients--by cytology or colposcopy--needs to be determined by randomised controlled trials. PMID:2224218

    Full Text Available Abstract Background The female lower genital tract is a gateway for pathogens entering the host through the mucous membrane. One of the prevalent human viruses is Torque teno virus (TTV. The major reported routes of TTV transmission are fecal-oral and parenteral. Furthermore, other modes of transmission, e.g. sexual contact, are suggested. To investigate the sexual route of TTV transmission, cervical smears of healthy women and those with cervical lesions were screened for the presence of TTV DNA. Methods TTV DNA was studied in cervical smears of 95 patients with cervical lesions and 55 healthy women. Paired serum samples were available from 55 and 42 women, respectively. All healthy women had normal cytology while 44 patients had histologically confirmed low-grade lesion (LGL and 51 high-grade lesion (HGL. TTV DNA was detected with primers specific for the non-coding region. In 40 paired cervical smears and serum samples, the phylogenetic group of TTV isolates was determined. The presence of HPV DNA in cervical smears was detected by means of PCR with MY09/11 primers. Results The prevalence of TTV DNA in cervical smears of healthy women was 52.7% and was comparable with that in paired serum samples (50%. Symptomatic women had significantly higher prevalence of TTV DNA in cervical smears (74.7% than healthy controls. The TTV DNA prevalence in patient serum samples was 51%. The phylogenetic groups of TTV serum isolates were concordant with those of TTV from cervical smears of the same subjects. In cervical smears, a wider variety of TTV isolates was found. The viral loads in cervical smears were 10 to 1000 times as high as in sera. The HPV-positive study subjects had significantly higher TTV DNA prevalence than HPV negatives. The prevalence of TTV was not associated with disease severity. Conclusion High prevalence of TTV in cervical smears suggests that sexual transmission is another mode of expansion of TTV infection among the population. The

  9. Agreement Between Visual Inspection with Acetic Acid and Papanicolaous Smear as Screening Methods for Cervical Cancer

    International Nuclear Information System (INIS)

    Objective: To determine degree of agreement between visual inspection with acetic acid (VIA) and Papanicolaous (Pap) smear as screening methods for cervical cancer. Study Design: A cross-sectional study. Place and Duration of Study: Department of Obstetrics and Gynaecology, Sir Ganga Ram Hospital, Lahore, from July to December 2012. Methodology: Two hundred and fifty women in reproductive age group presenting with various gynaecological complaints were included in the study. A Papanicolaous smear was taken and visual inspection with 5% acetic acid was done. VIA was reported as positive or negative according to acetowhite changes and cytology result was graded as CIN 1, 2, 3 and squamous carcinoma. Those women who showed positive result with either VIA or Pap smear or both were further subjected to colposcopic directed biopsy which was taken as gold standard. Results were computed using Statistical Package for Social Sciences (SPSS) version 16 and statistical test used was kappa. Results: Out of 250 women, VIA was positive in 55 (22%) patients and Pap smear was abnormal in 27 (10.8%). Histological diagnosis of CIN/cancer was made in 36 out of a total 62 patients who underwent biopsy. Conclusion: There was a fair agreement between VIA and Pap smear, with VIA detecting more abnormalities than cytology. In the absence of Pap smear availability, VIA may be a reasonable cervical cancer screening method, especially in low resource settings. (author)

    The definition of minimal relevant Pap smear abnormality is crucial for balancing the beneficial effects of screening (prevented mortality) with negative side-effects (the high positivity rate). After inflammation ceased to be defined as a borderline abnormal smear outcome in The Netherlands in...... 1996, the proportion of these smears dropped from 10% to less than 2%. Because this may have caused a loss in smear sensitivity, we analysed the changes in the incidence of cervical cancer after a negative Pap smear.

  17. Comparison of visual inspection of cervix and pap smear for cervical cancer screening

    International Nuclear Information System (INIS)

    Objective: To evaluate the performance of visual inspection of cervix (VIA) after application of 3% acetic acid in cervical cancer screening in comparison with PAP smear. Results: Out of 540 subjects, 356 were negative with both screening techniques. One hundred and fifty-six subjects were positive with VIA (28.9%) while PAP smear was positive in seventy-eight subjects (14.4%). The sensitivity of VIA was 93.9% and of PAP smear was 46.9%. Corresponding specificities were 30.4% and 69.5%. There was no significant difference between the positive predictive value (PPV) of both test (p<0.05). The accuracy of VIA was 77.5% compared to 52.8% of PAP smear. The difference was highly significant (p < 0.01). Conclusion: These results indicate that VIA is more sensitive and has a higher accuracy as compared to PAP smear. It could, therefore, be valuable in detection of precancerous lesions of cervix. Low cost, easy applicability and immediate results make VIA a useful screening test in developing countries like Pakistan as compared to PAP smear. (author)

    2007-10-01

    To enhance understanding of how having a cervical smear can lead some women not to keep up-to-date with this test, a hermeneutic (interpretative) phenomenological study was undertaken. Participants were six purposively selected New Zealand women -- predominantly Māori -- at least 6 months overdue for a follow-up cervical screen in the previous 6 years. Each woman gave an in-depth interview. Transcribed and analyzed via a general inductive approach, the interviews suggested that the smears can violate women's positive aloneness with their bodies, and magnify aloneness as a negative state. Overdueness for the test avoids these effects. To minimize such effects, primary health care needs to acknowledge and address these issues, for example by providing an opportunity to connect the aloneness to trusted others. PMID:17907011

    Prior to the introduction of a national cervical screening programme, death rates from cervical cancer in the Republic of Ireland were greater than the death rates in all other regions in Britain and Northern Ireland. The following audit compares the impact of the national cervical screening programme, established on 1 September \\'08, on uptake and results per age group screened before and after its implementation. This retrospective audit was carried out in a four-doctor practice with approximately 1554 GMS and 5000 private patients. Data over a ten month period in \\'08\\/\\'09 was collected from the practice record of cervical smears and compared to the same period in \\'07\\/\\'08. A cohort of 534 Irish urban women was included. A total number of 148 women were screened between October 2007 and July 2008 compared with 386 women screened over the same months in 2008\\/2009. Increase in uptake was most marked in the 25-44 years age group, 100 (\\'07-\\'08) vs. 303 (\\'08-\\'09). The majority of results for both time periods were negative (85% 07\\/08, 81% 08\\/09). There was a higher number of HSIL in \\'08-\\'09 (an increase from 1% to 3.37% of the total screened). This audit clearly supports the introduction of the national cervical screening programme showing both an increase in uptake and a increased pick-up of high grade lesions.

    The melanocytic cells of the cervical epithelium are capable of forming the complete spectrum of melanocytic lesions, from benign lentigines to melanoma. Primary malignant melanoma of the uterine cervix is a rare neoplasm with aggressive behavior. The absence of melanin pigment can lead to misdiagnosis as carcinomas, sarcomas, or lymphoma. Immunohistochemical studies should be used for confirmation. In order to consent the cervix as a primary site, exclusion of any other probable primary sites of melanoma is needed. Here, we present a 61-year-old female patient with postmenopausal vaginal bleeding. After cervical smear, diagnosis was confirmed by cervical punch biopsy. Diagn.

    This study aimed to explore attitudes towards cervical cancer screening among Japanese university students who had never had a Pap smear. Four focus-group discussions, each with 15 female university students, took place in November and December 2009. Discussions were recorded and transcripts were analyzed to extract attitudes of young women towards cervical cancer screening. The four themes that emerged were: i) a low sense of reality about cervical cancer; ii) a lack of knowledge about both cervical cancer and Pap smears; iii) a lack of motivation to get screened, and iv) a reluctance to visit the gynecologist. Participants who were interested in undergoing screening for cervical cancer cited the influence of conversations with friends and family, a diagnosis of cancer within their family, and relevant information from the media. The results indicate the importance of getting young women more interested in cervical cancer screening and overcoming their tendency to avoid visiting a gynecologist. PMID:23991995

    This study focuses on the meanings assigned to practices for cervical cancer prevention among women from low-income neighborhoods in Salvador, Bahia State, Brazil. This was a qualitative study based on content analysis of semi-structured interviews with 15 women 24 to 68 years of age. The results showed high appreciation of the Pap smear test, performed as part of routine gynecological examination (but without the patient necessarily having biomedical knowledge of its role). Besides accessibility and quality of health services, other factors influence the way the women assign meaning to cervical cancer prevention. Moral values associated with sexuality and gender influence risk perception, adoption of preventive practices, and interpretation of cervical cytology results. The ongoing practice of the Pap smear test is part of the construction of femininity, which is associated with maturity and personal responsibility for self care in a context of medicalization of the female body.

    Full Text Available Background. Despite the significant burden of cervical cancer, Malaysia like many middle-income countries relies on opportunistic cervical screening as opposed to a more organized population-based program. The aim of this study was to ascertain the effectiveness of a worksite screening initiative upon Papanicolaou smear test (Pap test uptake among educated working women in Malaysia. Methods. 403 female teachers who never or infrequently attended for a Pap test from 40 public secondary schools in Kuala Lumpur were recruited into a cluster randomized trial conducted between January and November 2010. The intervention group participated in a worksite cervical screening initiative whilst the control group received usual care from the existing cervical screening program. Multivariate logistic regression was performed to determine the impact of the intervention program on Pap smear uptake after 24 weeks of followup. Results. The proportion of women attending for a Pap test was significantly higher in the intervention than in the control group (18.1% versus 10.1%, P value < 0.05 with the worksite screening initiative doubling the Pap smear uptake, adjusted odds ratio 2.44 (95% CI: 1.29–4.62. Conclusion. Worksite health promotion interventions can effectively increase cervical smear uptake rates among eligible workers in middle-income countries. Policy makers and health care providers in these countries should include such interventions in strategies for reducing cervical cancer burden. This trial is registered with IRCT201103186088N1.

    Full Text Available Abstract Background Atypical glandular cells on cervical smears are often associated with clinically significant uterine lesions. The frequency and accuracy of AGC-NOS (i.e. atypical glandular cells, not otherwise specified diagnoses, regardless of the gland cell type or the degree of suspicion, and their outcome were investigated. Methods From January 1, 1990 to December 31, 1999 a total of 261 patients had an AGC-NOS diagnosis made by conventional cervical Papanicolaou smear interpretation representing 0.05% of all Pap-smears analyzed at the national level. 191 (73.2% patients had a subsequent histological examination, 8 samples were not representative by origin and were excluded. Results Out of 183 AGC-NOS diagnosed, 56.3% (103/183 were associated with tissue-proven precancerous and/or cancerous lesions, 44% being of endocervical and 56% of endometrial origin. 75% of all AGC-patients were asymptomatic. 66.7% (6/9 of the patients with subsequent invasive endocervical adenocarcinoma (AC and 56% (28/50 of those patients with invasive endometrial AC were without clinical symptoms. 3 patients out of 9 with an invasive endocervical AC were 35 years of age or less. 10.1% and 12.3% of all 'new' tissue-proven invasive endocervical or endometrial AC respectively recorded by the national Morphologic Tumour Registry (MTR were first identified by a cytological AGC-NOS diagnosis. Conclusion Our findings emphasize the importance of the cytological AGC-category even in the absence of a precise origin or cell type specification. 56% of the AGC-diagnoses being associated with significant cancerous or precancerous conditions, a complete and careful evaluation is required.

    Full Text Available Background: Cancer cervix is the leading cause of cancer deaths in females in developing countries and one in five women suffering from cervical cancer lives in India. Aims: The aim of this study is to determine the awareness about cervical cancer and Pap smear among nurses working in a tertiary care institute. Study Setting and Design: Cross-sectional survey in a tertiary care institute. Materials and Methods: Nurses working at our institute excluding those who have worked or working in the Obstetrics and Gynecology department were provided with a pre-designed questionnaire testing their knowledge about cervical cancer. Results: Approximately, 86% were aware about cancer cervix and 69% were aware of a pre-cancerous stage. 42.3% were not aware of any risk factor and 27.6% were not aware of any symptom of cancer cervix. 86.2% were aware about Pap smear, but only 58.6% were aware that facilities of Pap smear were available at our hospital. Conclusions: Knowledge about cervical cancer and awareness of Pap smear as screening test was inadequate in nursing staff. Awareness programs about cervical cancer and screening are needed to increase awareness for this preventable condition. Recommendation: There is a need to arrange reorientation programs to sensitize nurses and establish cytology clinics to offer facilities for easily accessible and affordable screening.

    Liquid-based cytology (LBC) has replaced conventional smear assessment in many centers over recent years. In our laboratory this transfer took place in 1999. At that time we performed a split sample study comparing the conventional method of cervical smear evaluation with the ThinPrep system. This split sample study identified a dramatic improvement in specimen adequacy with LBC. While 11% of conventional preparations were reported as unsatisfactory and almost 9% were reported as suboptimal, evaluation of the same cases using LBC saw this combined figure reduced to 2.3%. AIM: To evaluate whether this dramatic fall in unsatisfactory smears has been maintained with the use of LBC. The database for all smears reported for 2005 (100% LBC) was interrogated. The number of unsatisfactory reports was calculated. The reason for an unsatisfactory report was recorded for each case. The overall unsatisfactory rate was compared with that reported in the 1999 split sample study. A total of 41,312 smear tests were reported in 2005. 1,342 (3.25%) were reported as unsatisfactory. Our findings support the ongoing value of LBC in a routine cervical screening laboratory in terms of continuing to maintain a low rate of unsatisfactory smears.

    Full Text Available AIM: Carcinoma of the cervix, the second most common cancer among women remains a public health problem. Though this preventable cancer occurs more commonly in the developing world, it is almost non-existent in developed countries where there are well established screening programs. The aim of this study is to determine the degree of awareness and practice of cervical smear as a screening procedure for cervical cancer among female nurses in a tertiary health facility in south-south Nigeria. METHOD: Semi-structured questionnaires were distributed to all the female nurses at the University of Uyo Teaching Hospital. RESULTS: The ages of the respondents were between 21 - 60 years with the modal age group being 31- 40 years (48.9%. Majority of the respondents were married (59.7% and 36.4% of them had practiced nursing for over 10 years. Majority of the respondents (94.3% had heard of the cervical smear and 79.5% of the nurses knew that cervical smears were used to detect premalignant diseases of the cervix. Only 7.4% of the nurses had undergone screening for cervical cancer. Common reasons given by the respondents who had not screened were not being a candidate for cervical cancer (31.9% and ignorance as to where screening is done (28.8%. The most common sources of information about cervical smear were the hospital (87.5% and textbooks (13.6%. CONCLUSION: The level of awareness of the cervical smear as a preventive tool for cervical cancer was high but utilization of the test was disappointingly low. Modern concepts of cancer prevention and control should be included in the curriculum of the school of nursing and nurses should be involved in the organisation of health talks to members of the community on cervical cancer and its prevention. The print and electronic media should be made to participate in the dissemination of information on the prevention of cervical cancer in our environment. [TAF Prev Med Bull 2011; 10(6.000: 675-680

    Statistical Analysis Used: Chi-square test and logistic regression were used to find association and the significant predictor for doing Pap smear test. Results: Over half (53.3% of the participants had heard about cervical cancer and its detection method. More than half (60% and over a third (37.8% of the participants knew about human papilloma virus (HPV and multiple sexual partner respectively as risk factors for cervical cancer. More than half (55.3% indicated that they were not aware if cervical cancer can be prevented. Majority (76.7% knew that Papanicolau′s (Pap smear test is used for detection or prevention of cervical cancer. Among those who were sexually active and knew about Pap smear test 79.3% did not do the test mainly because of personal factors such as fear of the procedure, or were not ill. Conclusions: Level of awareness regarding cervical cancer and its detection method was low among these female students. The university management should focus on developing policies on health education and promotion to prevent transmission of the HPV.

  12. Herpes simplex virus in postradiation cervical smears. A morphologic and immunocytochemical study

    International Nuclear Information System (INIS)

    From January 1987 to August 1988, cytomorphologic criteria of both herpes simplex virus (HSV) and radiation effects were observed in Papanicolaou smears from 3 of 1,340 patients who had received radiotherapy for squamous cell carcinoma of the cervix. Avidin-biotin immunoperoxidase staining, using a rabbit IgG polyclonal HSV antibody, confirmed the presence of HSV antigen in those three postradiation smears. Both multinucleated molded cells and epithelial cells that lacked cytopathic effects were positive for HSV. Three other postradiation smears from these cases were similarly positive for HSV antigen; the one preradiation smear was negative. In situ hybridization and immunoperoxidase studies on sections from the preradiation biopsies were negative: severely altered neoplastic cells showed no reactivity. The absence of HSV markers in the preradiation specimens suggests that the HSV infections were secondary to the radiotherapy; further studies are needed to prove this association and to assess the possible mechanisms. These cases clearly indicate that the overlapping features of radiation and viral effects (such as multinucleation) may be present simultaneously

    Full Text Available The author analyzes an algorithm for identifying and treating w omen with cervical intraepithelial neoplasias (CIN and microinv asive cancer of the cervix uteri in cases of the hidden area of transformation and in the absence of visible cervical changes. There are excep- tional difficulties of making the diagnosis of epithelial damages due to the incomplete reproducibility of cytological abnormal ities and the low informative value of a histological study of scrapes from the cervical canal. To avoid hypodiagnosis, it is justifiable to prefer human papillomavirus testing (Hybrid Capture 2 (HC2 to repeat smears for the choice of a management tactic.

    2011-01-01

    The purpose of this study was to evaluate women's knowledge about cervical cancer, Pap smears, and human papilloma virus in relation to their cervical cancer screening behavior. This hospital-based study was conducted with a sample of 200 women: 100 women screened in the last three years and 100 non-screened women who attended a hospital located in the metropolitan area of Buenos Aires, between September 2008 and February 2009. Women at the hospital were surveyed using a structured questionnaire. Multiple logistic regression models were used to evaluate the relation of women's knowledge about Pap smears to screening behavior, controlling for socio-demographic characteristics. Of the women who had been screened, 49% compared to 73% of those not screened had inadequate knowledge about Pap smears (P = 0.001), and 47% of screened and 30% of non-screened women reported that they had ever heard about human papilloma virus (P = 0.013). In multivariate analysis, having adequate knowledge about Pap smears (odds ratio: 2.6 or 95%, confidence interval: 1.4-4.8) having health insurance (odds ratio: 2.6 or 95%, confidence interval: 1.1-6.4) and being married (odds ratio: 1.8 or 95%, confidence interval: 1.1-3.4) were the factors related to being screened in the previous three years. Knowledge was related to screening. Comprehensive educational approaches may enhance screening for cervical cancer prevention. PMID:21391162

  16. No biological evidence of XMRV infection in cervical smears from HIV/ HPV positive and negative Kenyan women.

    Directory of Open Access Journals (Sweden)

    Xiaotong He

    Full Text Available BACKGROUND: XMRV (xenotropic murine leukaemia virus-related virus is a gammaretrovirus first discovered in human prostate carcinomas and later linked to chronic fatigue syndrome (CFS. Emerging conflicting data and lack of reproducibility of results within the scientific community has now led to the association of XMRV with CFS being discounted. Indeed the case for an involvement with any human disease has been questioned with the suggestion that XMRV is a laboratory generated recombinant virus. The fact that not all published positive findings can be easily explained as contamination artefacts coupled with the observation that XMRV may have a sexually transmitted mode of infectivity and can be infectious for primates, where it preferential resides in cells of the reproductive tract, prompted us to look for evidence of XMRV in the cervical cells of a cohort of Kenyan women both with and without pre-existing HIV/HPV infections. RESULTS: Using a highly sensitive and selective triplex PCR approach we analysed DNA from the liquid based cytology (LBC cervical smears of 224 Kenyan women. There was no evidence of XMRV expression in any of the sample population irrespective of HPV and/or HIV status. CONCLUSIONS: The data presented show no indication of XMRV infection in any of the cervical samples screened in this study. Approximately 50% of the women were HIV positive but this did not influence the findings signifying that XMRV does not act as an opportunistic infection in this cohort nor is it related to HPV status. Our results therefore support the findings that XMRV is confined to the laboratory and does not currently represent an infectious agent for humans, with a cautionary adage that such potential zoonotic viruses should be carefully monitored in the future.

  18. Comparison of Visual Inspection with acetic acid and Pap smear in cervical cancer screening at a tertiary care hospital

    International Nuclear Information System (INIS)

    Objective: To determine the accuracy of visual inspection with acetic acid in comparison with Pap smear against colposcopic directed biopsy, for detection of pre-cancerous lesion. Methods: The comparative cross-sectional study was conducted at the Maternal and Child Health Centre (MCHC), Pakistan Institute of Medical Sciences (PIMS), Islamabad, from January to December 2010. Every married women with age range 19 to 51 years underwent conventional cytology and visual inspection with 5% acetic acid. Distinct acetowhite areas were taken as positive, while cervical intra-epithelial neoplasia on cytology was labelled as Pap smear positive. Colposcopic directed biopsy was taken as the gold standard. SPSS 13 was used for statistical analysis. Results: Of 519 subjects, 70(13.4%) were screened positive and 29(5.6%) were biopsy positive for cervical intra-epithelial neoplasia. Of these, 26(37.1 %) were positive on visual inspection; 14 (20 %) on cytology; and 30 (42.8%) on combined test. The sensitivity of visual inspection was 78.5% vs 61.1% for Pap smear (p<0.001). The specificity of visual inspection was 99.3% vs 99.4% for cytology (p<0.1). Significantly higher sensitivity and specificity was found for the combined test than either of the two alone; 93.1% and 99.1% respectively (p<0.001). The positive predictive value of visual inspection vs pap was 84.6% vs 78.5% (p<0.001) and negative predictive value was 98.6% vs 96.5% (p<0.1). Both values of combined test were significantly higher than either of the two tests alone (p<0.01). Conclusion: Visual inspection with acetic acid has significantly higher sensitivity than Pap smear and may replace pap smear as a primary screening tool for universal screening. Combined test with higher predictive accuracy may be used for opportunistic screening. (author)

  19. A molecular monopoly? HPV testing, the Pap smear and the molecularisation of cervical cancer screening in the USA.

    Hogarth, Stuart; Hopkins, Michael M; Rodriguez, Victor

    2012-02-01

    DNA-based molecular testing for human papillomavirus has emerged as a novel approach to cervical cancer screening in the context of well-entrenched existing technology, the Pap smear. This article seeks to elucidate the process of molecularisation in the context of screening programmes. We illustrate how, although Pap has long been problematised and could be seen as a competing technological option, the existing networks and regime for Pap were important in supporting the entrenchment process for the artefacts, techniques and new diagnostics industry entrant, Digene, associated with the new test. The article provides insights into how the molecularisation of screening unfolds in a mainstream market. We reveal an incremental and accretive, rather than revolutionary, process led by new commercial interests in an era when diagnostic innovation is increasingly privatised. We show Digene's reliance on patents, an international scientific network and their position as an obligatory point of passage in the clinical research field with regard to the new technology's role, as well as on controversial new marketing practices. The article is based on a mixed method approach, drawing on a wide range of contemporary sources (including patents, statutory filings by companies, scientific literature and news sources) as well as interviews.

    Full Text Available Background Cervical carcinoma is one of the most common causes of mortality among women.Early detection can be done by Papanicolaou (Papsmear test - a simplest, safe, cost effective and non invasive procedure. The main objective of this study was to categorize Pap smears for cytohistologicalexamination as well as clinically correlate to analyze sensitivity, specificity and positive predictive value of Pap smear. Methods In this prospective study 417 Pap smears performed, cytohistological correlation was done in 104 cases because patients had undergone both Pap smear and cervical biopsy.Detailed history was taken and clinical examination was done. Pap smear sample was collected from cervix and reporting was made according to Bethesda 2001 classification.Cytological findings were correlated with histopathology. Results Overall concordance rate was 60.7%. Concordance rate for malignancy was 100%, for inflammatory lesions 70.8% and for cervical intraepithelial neoplasia (CIN 33.3%. Common age group presented for screening was40-50 years.Commonest clinical presentationwas bleeding per vaginum. Conclusion The study provides good cyto-histopathology correlation in detecting high grade lesions and malignancy. Although Pap smear sensitivity was low but can be increased by adequate sampling and avoiding technical errors.Bethesda system is strongly recommended for adequacy of sampling to minimize inconsistency.Regular screening should be advised to the patients for the early detection of cervical carcinoma.

    Full Text Available Context and Aim: Screening programs using conventional cytology conventional Pap smear (CPS have successfully reduced cervical cancer, but newer tests like liquid-based cytology (LBC and human papillomavirus testing might enhance screening. The main aim of the present study was to assess the diagnostic accuracy of LBC versus CPS using "split samples." Materials and Methods: This was a prospective study comprising of 1000 consecutive cervical "split samples" over a period of 1 year. Split sample was obtained using cervex-brush. CPS was prepared from the brush and the brush head was suspended in the LBC vial and processed by SurePath™ LBC. Results: There were 4.3% unsatisfactory (U/S cases in CPS and 1.7% in LBC; the main cause is insufficient cells, and excess of blood in CPS. About 25/100 (2.5% split samples had epithelial abnormalities both in CPS and LBC (1.2%-atypical squamous cells of undetermined significance; 0.4%-low grade squamous intraepithelial lesion; 0.2%-high grade squamous intraepithelial lesion; 0.5%-squamous cell carcinoma; 0.1%-atypical glandular cells favouring neoplasia; 0.2%-adenocarcinoma. Inflammatory organisms were almost equally identified in both techniques but were better seen in LBC samples. Conclusions: LBC technique leads to significant reduction of U/S rate. LBC samples offered better clarity, uniform spread of smears, less time for screening and better handling of hemorrhagic and inflammatory samples. LBC had equivalent sensitivity and specificity to CPS.

    Results: The overall frequency of normal, inadequate, inflammatory, and abnormal smears was 11.86%, 5.73%, 74.98% and 13.2% respectively. Atypical squamous cell carcinoma of undermined significance (ASCUS was seen in 3.61%, squamous intraepithelial lesion (SIL was seen in 5.36%, low grade squamous intraepithelial lesion (LSIL was seen in 2.59% while high grade squamous intraepithelial lesion (HSIL was seen in 2.77%. Invasive carcinoma was seen in 3.69%. The premalignant epithelial abnormalities like ASCUS, LSIL and HSIL were found to be highest in the age group of 31-50 years in our study, which correlated well with other similar studies. Conclusions: Hence we should advocate regular cervical cytology (PAP smear study, which can help to treat cervix lesions early before the progress into cervical cancer. Early detection is the only key to saving a woman's life as the later the abnormalities are discovered; mortality, morbidity and treatment cost all increase.

    .OBJECTIVE: To identify and evaluate the predisposing factors regarding the utilization of the Pap smears in the population seen in the Cervical Cancer Screening Program in Mexico METHODS: A cross-sectional study was conducted from January 1997 through December 1998 in Mexico city. A questionnaire was applied to a total of 2,107 women of reproductive age who attended a family planning program and data was collected regarding the following topics: social-demographics, reproductive risk factors associated with cervical cancer, sexual behavior and partner history, birth control, knowledge about Pap smear' benefits, and its utilization. Statistic analysis was conducted using Student´s test and non-conditional multiple logistic regression model for determining significance. RESULTS: The predisposing factors were: knowledge about Pap smear's benefits (OR=6.00, CI 95% 4.70-7.67, history of using at least two birth control methods (OR=2.38, CI 95% 1.75-3.24, previous history of vaginal infection (OR=2.18, CI 95% 1.73-2.75, sexual partner's approval of gynecological examinations (OR=1.56, CI 95% 1.07-2.29. CONCLUSIONS: Educational programs on cancer prevention in this population should include the benefits of screening tests. Pap smears for Mexican women of reproductive age are mostly offered opportunely. The previous use of health services is a determinant factor for the utilization of the Cervical Cancer Screening Program. These results show the need to strengthen health promotion programs to women at high risk of cervical cancer and their sexual partners.

    Full Text Available Abstract Background Almost one-third of Norwegian women aged 25–69 years invited to have a Pap smear do not attend during the recommended period, and thus constitute a population with high-risk of cervical cancer (CC. Since the incidence of precancerous lesions of the cervix peak with occurrence of pregnancies within the same decade in women aged 25 to 35 years of age, antepartum care presents an opportunity to offer a Pap smear thereby increasing the coverage of the programme. The study objective was to describe the effect of the antepartum Pap smear on the coverage of a cytological CC screening programme. Methods Among 2 175 762 women resident in Norway in 31.12.1996, all women who gave birth in 1996–7 were identified from the Medical Birth Registry of Norway. Attendance to the cervical cancer screening was assessed by linkage to the Cytology Registry separately for the pregnant and non-pregnant women cohorts. The results were stratified by age, history of previous Pap smear and history of invitation to the CC screening programme. Logistic regression was used to estimate the relative probabilities of having a Pap smear adjusted for age, screening history, and time since invitation, for pregnant and non-pregnant women, respectively. Results 69% of the pregnant women had a Pap smear during one year of follow-up since beginning of the pregnancy with the majority taken during the antepartum period. Irrespectively of age or history of having a Pap smear, pregnant women were 4.3 times more likely to have a Pap smear during follow-up compared to non-pregnant women. 63.2% of the pregnant women had a smear as response to the invitation letter compared to 28.7% of the non-pregnant women, OR = 2.1 (95% CI 1.9 to 2.4. As an indication of "over-screening", 5397 pregnant women (57.8% with a smear shortly before the start of follow-up also had a new Papsmear, compared to 83 023 (32.3% in non-pregnant. Conclusion Pap smear screening during pregnancy

  14. Specific identification of human papillomavirus type in cervical smears and paraffin sections by in situ hybridization with radioactive probes: a preliminary communication

    International Nuclear Information System (INIS)

    Cervical Papanicolaou smears and paraffin sections of biopsy specimens obtained from women attending dysplasia clinics were examined for viral DNA sequences by in situ hybridization technique using 35S-labeled cloned recombinant DNA probes of human papillomavirus (HPV) types 6, 11, and 16. These and one unrelated DNA probe complementary to measles virus RNA were labeled by nick translation using either one or two 35S-labeled nucleotides. Paraffin sections and cervical smears were collected on pretreated slides, hybridized with the probes under stringent or nonstringent conditions for 50 h, and autoradiographed. Additional cervical specimens from the same women were examined for the presence of genus-specific papillomavirus capsid antigen by the immunoperoxidase technique. Preliminary results may be summarized as follows. The infecting virus could be identified in smears as well as in sections. Viral DNA sequences were detected only when there were condylomatous cells in the specimen and in only a proportion of the condylomatous cells. Even under stringent conditions, some specimens reacted with both HPV-6 and HPV-11. In some instances, the cells did not hybridize with any of the three probes even when duplicate specimens contained frankly condylomatous, capsid antigen-positive cells. In situ hybridization of Papanicolaou smears or of tissue sections is a practical method for diagnosis and follow-up of specific papillomavirus infection using routinely collected material

    Full Text Available Objective: Due to the low sensitivity of Pap smear, premalignant lesions of the cervix can be missed in women with inflammatory Pap smears. However, it is not practically possible to subject all women with inflammatory Pap smear to colposcopy. This study was carried out with the aim to evaluate whether women with persistent inflammation on Pap smear need further evaluation with colposcopy. Materials and Methods: Four hundred and twenty women were screened at a tertiary level hospital with Pap smear. Women with inflammation on Pap smear were given treatment as per WHO guidelines and Pap smear was repeated at an interval of 6-12 weeks. Women with persistent inflammation on Pap smear were then subjected to colposcopy and directed biopsy if required. Results: Of the 420 women screened, 102 (24.3% women had a Pap smear showing inflammation. Thirty six women (8.6% had persistent inflammatory Pap smear. Thirty women were subjected to colposcopy and 16 (53.3% had abnormal findings on colposcopy. Five out of these 30 women (16.67% had Cervical intraepithelial neoplasia (CIN on biopsy. Conclusions: Nearly 16.67% women with persistent inflammation on Pap smear had cervical intraepithelial neoplasia. Hence, a large number of women with CIN would be missed if persistent inflammation on Pap smear is not evaluated further.

    BACKGROUND This study aimed to examine the positive and negative predictive value in the diagnosis of premalignant and malignant lesions of cervical colposcopy, the sensitivity and specificity of smear, and to evaluate the correlation with histopathology of abnormal cytology and colposcopy. MATERIAL AND METHODS The criteria for inclusion of patients with unhealthy cervix in the study were: Erosion, Chronic cervicitis, and Healed lacerations, Hypertrophied cervix, bleeding on touch, suspicious growth/ulcer/polyp on the cervix, and abnormal discharges from the cervix. Women with frank carcinoma cervix, pregnant females, patients with bleeding per vaginum at the time of examination, and those who had used vaginal medications, vaginal contraceptives or douches in the last 48 h of examination were excluded from the study. Demographic analysis was performed for 450 patients who were admitted to the clinic. Sensitivity, specificity, positive predictive value and negative predictive values of patients to identify cervical pathologies of smear and colposcopy were histopathologically calculated. The statistical software package SPSS 15.0 (SPSS Inc., Chicago, IL, USA) and Spearman's and Chi-Square tests were used for statistical analysis. RESULTS Sensitivity, specificity, PPD and NDP of smear were 0.57%, 0.76%, 0.26%, 0.92% respectively. Sensitivity, specificity, PPD and NDP of colposcopy were 0.92%, 0.67%, 0.52%, 0.96% respectively. A statistically significant correlation was found between abnormal cytology and histopathology, and abnormal colposcopy finding and histopathology. CONCLUSIONS Women with clinical diagnosis of unhealthy cervix should be evaluated by cytology to detect any premalignant or malignant lesions. It was concluded that Pap smear, colposcopy and histopathology should be collectively evaluated to evaluate cervical findings in low socio-economic regions. PMID:26655816

    Full Text Available Background: The purpose of our study was to determine the prevalence and significance of psammoma bodies (PBs in the cervicovaginal smears of the screening population of Trento district (Italy, with the description of the cytological presentation of an asymptomatic bilateral ovarian psammocarcinoma. Methods: From 1993 to 2006, women with PBs detected on consecutively screened cervical smears were identified from the computerized pathology database of Rovereto Hospital. The follow-up period was set from the time of cytological diagnosis to May 31 st , 2007. Clinical information was obtained from retrospective review of women′s medical records. The source of PBs was identified with adequate diagnostic procedures. Results: PBs were found in six of the 201,231 Papanicolaou screening smears (0.0029%. Benign conditions (intrauterine device, inclusion ovarian cysts and ovarian cystoadenofibroma with PBs were found in four patients. In two cases, PBs were associated with malignant cells; a bilateral ovarian malignancy was diagnosed in both cases, a serous adenocarcinoma and a psammocarcinoma. Conclusion: PBs in the cervicovaginal smears are a rare finding, associated more often with benign conditions than with malignancies. Moreover, to our knowledge, our case of primary ovarian psammocarcinoma is the first report in which the presence of malignant cells and PBs in the cervicovaginal and endometrial smears represents the first manifestation of disease.

    Objective To evaluate the feasibility and reliability of record linkage of existing population-based data sets to determine Indigenous status among women receiving Pap smears. This method may allow for the first ever population measure of Australian Indigenous women's cervical screening participation rates. Setting/participants A linked data set of women aged 20–69 in the Queensland Pap Smear Register (PSR; 1999–2011) and Queensland Cancer Registry (QCR; 1997–2010) formed the Initial Study Cohort. Two extracts (1995–2011) were taken from Queensland public hospitals data (Queensland Hospital Admitted Patient Data Collection, QHAPDC) for women, aged 20–69, who had ever been identified as Indigenous (extract 1) and had a diagnosis or procedure code relating to cervical cancer (extract 2). The Initial Study Cohort was linked to extract 1, and women with cervical cancer in the initial cohort were linked to extract 2. Outcome measures The proportion of women in the Initial Cohort who linked with the extracts (true -pairs) is reported, as well as the proportion of potential pairs that required clerical review. After assigning Indigenous status from QHAPDC to the PSR, the proportion of women identified as Indigenous was calculated using 4 algorithms, and compared. Results There were 28 872 women (2.1%) from the Initial Study Cohort who matched to an ever Indigenous record in extract 1 (n=76 831). Women with cervical cancer in the Initial Study Cohort linked to 1385 (71%) records in extract 2. The proportion of Indigenous women ranged from 2.00% to 2.08% when using different algorithms to define Indigenous status. The Final Study Cohort included 1 372 823 women (PSR n=1 374 401; QCR n=1955), and 5 062 118 records. Conclusions Indigenous status in Queensland cervical screening data was successfully ascertained through record linkage, allowing for the crucial assessment of the current cervical screening programme for Indigenous women.

    Objective: Papanicolou (Pap) smear screening has dramatically reduced the incidence of invasive cervical can-cer worldwide. Pap smear screening is still not widely available in developing countries and therefore cannot be used as mass screening tool. This study was designed to establish the role of Pap smear as a routine investigation for females presented to gynecological department. Methods: It was a hospital based study. Patients attending with complaints including irregular vagi-nal bleeding, vagina discharge, dyspareunia, low backache or lower abdominal pain and primary or secondary infertility were included in the study. All these patients underwent pap smear. Results: Age of females was 25 to 60 years. Ninety females had dysplasia. Mild to moderate dysplasia was positive in 84 females. Six patients had severe dysplasia suspicious for squa-mous cell carcinoma (SCC) which was confirmed as invasive SCC on biopsy. All patients with mild to moderate dysplasia were regularly followed at 4 to 6 months. Thirty patients were lost during follow up. Forty had negative smear at 6 months, while fourteen having persistent dysplasia on repeated pap smears were referred for biopsies. Histopathology confirmed invasive SCC in five patients while chronic cervicitis was reported in nine patients. Only two of screened patients with high suspicion for cancer showed false negative results. Directed biopsies done in these confirmed invasive SCC. Conclusion: Pap smear is a useful, simple, non-invasive and reliable screening tool for cervical cancer. It may be practiced as a routine investigation in outpatients in developing countries, where mass screening is not available.

    Full Text Available O câncer de colo uterino apresenta alta mortalidade no Brasil, apesar dos programas para rastreamento. O objetivo deste estudo, de corte transversal, foi analisar conhecimento, atitude e prática do exame de Papanicolaou e entender a não adesão das mulheres a este exame. Foram entrevistadas 138 mulheres: noventa com neoplasia intra-epitelial de alto grau e 48 com câncer invasivo de colo uterino. As mulheres com câncer invasivo tiveram prática mais inadequada do exame. No entanto, independente do diagnóstico, mais de 80% delas referiram desmotivação/vergonha, 60% relataram que os médicos não examinavam e, cerca de 50% apontaram o tempo de espera para a consulta e a demora no agendamento como dificuldades para serem atendidas. Em geral, a prática do exame dependeu da iniciativa do médico e a periodicidade da coleta foi determinada pela procura de consulta devido a sintomas. As mulheres com 56 anos ou mais mostraram maior inadequação no conhecimento, na atitude e na prática. No entanto, aquelas com maior escolaridade conheciam melhor o exame. A maior idade e a menor escolaridade podem estar associados a não adesão das mulheres ao exame, porém as dificuldades sociais e econômicas para conseguir atendimento em saúde precisam ser consideradas para aumentar a prática do exame.Despite screening programs, Brazil has a high cervical cancer mortality rate. The objective of this cross-sectional study was to analyze knowledge, attitudes, and practices related to the Pap smear and to understand why women fail to submit to this screening test. A structured questionnaire was used to interview 138 women: 90 with high grade intraepithelial neoplasia and 48 with invasive cervical cancer. Inadequate practices were more frequent among women with invasive cancer. In terms of difficulties in obtaining medical care, more than 80% of women reported lack of motivation, 60% reported that physicians failed to conduct a complete physical examination

    To assess the understanding of the term 'Pap smear' among women across the entire adult lifespan after recent changes to the guidelines on cervical cancer screening. Women attending the Obstetrics and Gynecology clinic at a large safety net teaching hospital in a Midwestern city were provided one of two versions of a confidential and anonymous survey to complete. The difference between the two versions was the way the primary research question was worded. There were 174 participants ranging in age from 15 to 69 (mean = 33.9) years. Of the 73 women who completed version A of the survey, 74 % were able to identify at least one correct descriptor for the term 'Pap smear.' Women who could identify at least one correct descriptor for the term 'Pap smear' were on average older than those who could not (mean = 36.9 vs. 28.7 years; p = 0.012). Of the 94 patients completing survey version B, 67 % could not differentiate a pelvic exam from a Pap smear. There was no association between age and ability to differentiate a pelvic exam from a Pap smear. The majority of women cannot distinguish a Pap smear from a pelvic exam. The unexpected finding of less understanding among younger women prompts a need for further research and invites discussion of whether more cervical cancer prevention education, with more emphasis on HPV vaccines in recent years, has neglected the importance of Pap smears-which is beginning to show up in knowledge of younger women. Both these findings suggest a need for increased patient education during female preventive health clinic visits. PMID:25630404

    Full Text Available The Human Papilloma Virus (HPV has significant importance in invasive cervical cancer etiology of and its precursory injuries. Thus, it is necessary the application of molecular methodologies for the precocious diagnosis of this infection. This research has evaluated the effectiveness of Hybrid Capture System (HCS in detecting pathogenic types of HPV. HCS was compared with empirical established cytological criteria in specimens with cellular alterations that were suggestive of HPV infection. The presence of HPV was also evaluated in cytological normal specimens with inflammation and Cervical Intraepithelial Neoplasia (CIN. One hundred and eight women, suspected of HPV infection (clinical or cytological suspicion, were selected. Results demonstrated that both methods were complementary, since Hybrid Capture confirmed results of the cytology. The two methods may be used together to improve the diagnosis. Furthermore, the use of Hybrid Capture test in HPV diagnosis allows the identification of the risk that the virus proportionate.

    Full Text Available Abstract Background Cervical smears exhibiting unequivocal features of 'low grade squamous intraepithelial lesion' (LSIL are occasionally also admixed with some cells suspicious for, but not diagnostic of, 'high grade squamous intraepithelial lesion' (HSIL. Only a few studies, mostly reported as abstracts, have evaluated this concurrence. In this study, we evaluate the current evidence that favors a distinct category for "LSIL, cannot exclude HSIL" (LSIL-H, and suggest a management algorithm based on combinations of current ASCCP guidelines for related interpretations. Methods We studied SurePath™ preparations of cervical specimens from various institutions during one year period. Cytohisto correlation was performed in cases with cervical biopsies submitted to our institution. The status of HPV DNA testing was also noted in some LSIL-H cases with biopsy results.

    Concomitant infection with Aspergillus species and cervical squamous cell carcinoma in the female genital tract is a rare occurrence and attributed to the opportunistic nature of infection in the immunocompromised state due to the underlying malignancy. The contamination of smears with Aspergillus species should be excluded. The diagnosis of Aspergillus species infection along with squamous cell carcinoma was established on cervicovaginal pap smears in a 62-year-old female presented to gynecological clinic with complaints of stress urinary incontinence. Speculum examination revealed first-degree cervical descent. Smears showed features of squamous cell carcinoma along with fungal spores and fruiting body with hyphae of Aspergillus species. The presence of fruiting bodies and hyphae of Aspergillus species with coexisting squamous cell carcinoma is rare in routine pap smears. True infection needs to be distinguished from contamination by Aspergillus species. Early diagnosis can be established on routine cervicovaginal Pap smear examination. PMID:24272933

    George N. Papanicolaou (1883-1962) was born in Kymi (on the island of Euboea, Greece). He studied medicine in Athens but chose not to join his father's practice in Kymi. Instead, he obtained his doctoral degree at the Zoological Institute in Munich (1910) and - after a brief return and marriage in Greece - went to work at the Oceanographic Institute in Monaco. Recalled in 1912 by the death of his mother and the Balkan Wars, he and his wife emigrated a year later to New York. After some difficulty, he found work as a research biologist at the Cornell University Department of Anatomy. Papanicolaou concentrated on vaginal cells right from the start, initially from guinea pigs. His real goal was to harvest egg cells for the study of sex differentiation; he succeeded in finding the right time by recording the cyclic changes in genital epithelium. These same changes appeared to occur during the human menstrual cycle. It was by chance that he encountered cancer cells in a human specimen in 1928. More than 10 years would pass before he took up the subject of cancer again, in collaboration with the gynaecologist Herbert F. Traut (1894-1963). After their first publication in 1941, Papanicolaou gradually fine-tuned the technique of cytological diagnostics in a variety of organs. In 1961, he moved to Miami Beach as head of a new cancer centre, but suddenly died a few months later. PMID:23031235

    Full Text Available Background: In the low resource settings of a developing country, a conventional Papanicolaou (Pap test is the mainstay screening system for cervical cancer. In order to counsel women and to organize a public health system for cervical cancer screening by Pap smear examination, it is imperative to know the pattern of premalignant and malignant lesions. This study was undertaken to find out the prevalence of an abnormal Pap smear, in a tertiary hospital of a developing country, and to carry out a clinicopathological and demographical analysis for establishing the pattern of epithelial cell abnormality in a Pap smear. Materials and Methods: A cross-sectional descriptive study was carried out in a total of 1699 patients who underwent Pap smear examination. The prevalence of epithelial cell abnormality in the Pap smear was calculated in proportions / percentages. Specimen adequacy and reporting was assessed according to the revised Bethesda system. Results: Among the total of 1699 patients who had their Pap smear done, 139 (8.18% revealed epithelial cell abnormality. Altogether 26 smears revealed high-grade lesions and malignancy, most of which were found to be in women belonging to the 30 - 39 and ≥ 45 age group. A total of 75 (53.96% women were in the 20 - 44 age group and 64 (46.04% were in the ≥ 45 age group. A bimodal age distribution was detected in the epithelial cell abnormality, with the bulk being diagnosed in patients aged 45 or above. Overall one-third of the patients with an abnormal Pap smear result showed healthy cervix in per vaginal examination. Conclusions: A raised prevalence of epithelial cell abnormality reflects the lack of awareness about cervical cancer screening. Women aged 45 or above harbor the bulk of premalignant and malignant lesions in the Pap smear, signifying that these women are among the under users of cytological screening.

    In developing countries like India, occurrence of Human papillomavirus (HPV) in cervical cancer as well as in the asymptomatic population was observed to be very high. Studies on HPV prevalence have been conducted in different parts of the country but no data were available from the eastern region of Uttar Pradesh (UP). The present study aimed to determine the status of HPV prevalence and its association with different socio-demographic factors in this population. Prevalence of HPV was investigated in a total of 2424 cervical scrape samples of asymptomatic women. Primer sets from L1 consensus region of viral genome were used to detect the presence of HPV, and the positive samples were genotyped by sequencing. Univariate binary logistic regression analysis was used to evaluate association of socio-demographic factors with HPV. 9.9% of the clinically asymptomatic women were found to be infected with HPV comprising 26 different genotypes. Among HPV-positive women, 80.8% showed single infection, while 15.4% harboured multiple infections. HPV-16 (63.7%) was the most prevalent, followed by HPV-31 (6.7%), HPV-6 (5.4%), HPV-81 (4.6%) and HPV-33 (4.2%). Significant association of HPV with non-vegetarian diet ( < 0.05) and rural residential areas ( < 0.01) were observed. High prevalence of HPV-16 in asymptomatic women of this population, a frequency comparable to invasive cervical cancers, highlights an urgent need for a therapeutic HPV vaccine covering HPV-16 and other high-risk types to provide protection against the disease.

    We investigate a variant of hypercubic gauge link smearing where the SU(3) projection is replaced with a normalization to the corresponding unitary group. This smearing is differentiable and thus suitable for use in dynamical fermion simulations using molecular dynamics type algorithms. We show that this smearing is as efficient as projected hypercubic smearing in removing ultraviolet noise from the gauge fields. We test the normalized hypercubic smearing in dynamical improved (clover) Wilson and valence overlap simulations. (orig.)

    Although prevalence of Enterobius vermicularis (EV) infestation in Intestines ranges from 35% to 70%, its prevalence in female genital tract is not known despite several incidental findings. Acute inflammatory cells in the background of cervical Pap smear indicate infestation and should not be neglected as contamination. A 40-year-woman presented with white vaginal discharge persistent for past 1 year. Local examination showed hypertrophied cervix with eversion of both lips and hard consistency of the anterior lip of cervix. A clinical diagnosis of cervical carcinoma was made. However, cervical Pap smear indicated EV eggs in an inflammatory background, treatment to which resulted in completely recovery. PMID:26283859

    Full Text Available Background: Cervical cancer is the most common cancer in Indian women and is a preventable cancer. Pap smear being an expensive screening test, increased emphasis is being laid on the development of a reliable and cost effective screening method for cervical cancer. This study aims at early detection of cervical dysplastic lesions using a simple and cost-effective screening test like visual inspection of cervix with 3% acetic acid (VIA and comparing its diagnostic efficacy with the more expensive Pap screening by Bethesda method. Methods: Ours was a prospective study carried out on a 100 sexually active women aged 25-50 years, coming to our OPD. The women were subjected to both a VIA and Pap smear. All Pap and VIA positive women were subjected to a cervical biopsy, whose histopathological report was taken as the gold standard. Results: In our study the sensitivity of VIA was more than that of cytology (100% versus 66.67% but the specificity was significantly lesser (47.83% compared to the 73.91%. The negative predictive value of VIA was comparable with Pap smear (100% and 85% respectively as was the positive predictive value (42.86% and 50%. However the diagnostic accuracy of VIA was lower than that of Pap smear (66.67% and 81.25% in our study. Conclusions: In this study VIA was found to have efficacy comparable to Pap smear in screening cervical cancer. Thus we recommend that VIA could be used as an alternative screening tool to detect early cervical dysplasia - especially in poor resource settings.

    Full Text Available ABSTRACT: BACKGROUND: Trichomonas vaginalis is sometimes seen in Papanico laou stained smears, but because emphasis is placed on malignant cells in Papanicolaou stained smears, not much is done to search for this parasite in smears. In this study, cervical and vaginal specimens were examined by conventional Papanicolaou method fo r the presence of Trichomonas vaginalis microscopically. MATERIALS AND METHODS: Five hundred high vaginal swabs collected from gynaecology OPD were stained with Papanicolaou stain. RESULTS: One hundred and fifty (30% out of 500 Papanicolaou stained smea rs screened, were positive for Trichomonas vaginalis. Out of them 76.67% of positiv e smears were from asymptomatic females. Presumptive diagnosis based on perinuclear halo and complete T. vaginalis had the highest sensitivity of 69.33%, while diagnosis base d on perinuclear halo alone was 50.66% and 41.33% for diagnosis based on identification of com plete organisms in Pap smear

    Full Text Available BACKGROUND The cytologic diagnosis of cervical smears has become a very important screening test for the detection of pre-invasive and invasive cervical epithelial abnormalities. MATERIALS AND METHODS It is a prospective study conducted for a period of 1 year in 100 women who fulfilled the inclusion criteria. Colposcopy, PAP smear and biopsy were done. RESULTS Majority 70.5% i.e., (12/17 of CIN occurred in the age group of 30-49 years. Among the 9 women who took OCP, 12% (2/17 had CIN. Incidence of CIN in the permanently sterilized group was 59% (10/17 and among IUCD user was 5.9% (1/17. Among women who were diagnosed to have CIN, 70.5% (12/17 complained of excessive vaginal discharge 11.7% (2/17 of women had post-coital bleeding. PAP smear had a sensitivity of 29% and a specificity of 88% which was attributed to the high number of false, negative smears. Colposcopy showed a sensitivity of 82% and a specificity of 81%. Sensitivity was more than pap smear but specificity was less than pap smear. Accuracy of Colposcopy was found to be 82% which was comparatively more accurate than pap smear (78%. CONCLUSIONS COLPOSCOPY offers an excellent tool in evaluating cervical lesions. It is an easy and perspective method and its importance lies in teaching, diagnosis and management of cervical lesions, both neoplastic and non-neoplastic.

    Full Text Available To assess the hypothesis that combined Oral Contraceptive (OCs increase the risk of cervical neoplasia, we conducted a multicenter Case-Control study in Mashhad, the capital of Khorasan province. Seventy-eight women with moderate to severe dysplasia at Pap smear as case group and one hundred fifty nine women with normal Pap smear were selected as the control group for evaluation. The both case and control groups were matched by age, parity and socioeconomic status. All of the women in this study were single partner as husband and no smoker. 30 percent of cases and 64.8 percent of controls were used OCs. The duration of OCs use was the same in both. The odds ratio for OCs consumption was 0.2 with 95% confidence interval 0.11-0.4 in Logistic regression analysis. In contrast to some other studies, our findings showed an association between OCs and cervical dysplasia and there was a protective effect of OCs for cervical dysplasia.

    Full Text Available The 1991 Bethesda System for cervical/vaginal cytology reporting has defined adequacy criteria, including unsatisfactory designation. Most laboratories in USA and a few laboratories in Iran have implemented these criteria, but only few studies about clinical implications have been performed. All unsatisfactory Papanicolaou (Pap smears taken between August 2000 and March 2002 were retrieved from the file of cytologic reports of Mirza Koochak Khan Hospital's Department of Pathology. Of 4,598 total Pap smears 204 (4.4% were unsatisfactory (corresponding atypical rate of 2.5% and a SIL/carcinoma rate of 0.97%. About 20.2% of unsatisfactory Pap smears were from patients with a history of epithelial abnormalities. The majority (71 of 204 specimens; 35% of follow-up Pap smears or biopsies occurred within 6 months,12% within 6-12 months,1% within 12-18 months and 1% after 18 months. Approximately 59% had no follow-up. The first repeat Pap smear or histologic specimen in 83 patients with follow-up was negative in 71 (85%, unsatisfactory in 2(2.4%, epithelial cell abnormality in 11 (13.2% and atypical squamous cells of undetermined significance in 4(4.8%. Nonmalignant conditions contributing to the unsatisfactory smears on histologic specimens (23% included cervicitis, endocervical polyp and endometritis. Majority of patients with unsatisfactory Pap smears were followed up within 6 months. A significant number(13.2% of those with follow-up had eventual diagnosis of epithelial cell abnormality. Benign pathologic conditions also contributed to unsatisfactory smears. These patients were more likely to have a history of abnormalities. Unsatisfactory specimens are associated with benign as well as preneoplastic/neoplastic conditions. Clinical correlation should be the first step in delineating the cause of the unsatisfactory diagnosis.

    negative rate. OBJECTIVE: The aim of this study was to compare the performance of 100% rapid re-screening with that of 10% random re-screening as an internal quality assurance method. METHODS: 2,750 first screening negative smears were submitted to 100% rapid re-screening by a senior cytotechnologist followed by 10% random re-screening by another senior cytotechnologist. After re-screening, all smears were analyzed by two independent cytopathologists. Whenever results were divergent the smears were analyzed by a third cytopathologist and the panel established a consensus gold standard diagnosis. RESULTS: 98 suspect smears were selected by rapid re-screening, 62 of which were confirmed as abnormal by the gold standard: 45 Ascus, 11 LSIL and six HSIL (sensitivity 73.8%. Of the nine abnormal smears detected by the 10% random re-screening, six were confirmed by the gold standard, three Ascus, two LSIL and one HSIL (sensitivity 50%. The gold standard detected 57 Ascus, ten LSIL and five HSIL cases among the 2,489 smears that were not submitted to 10% re-screening. CONCLUSIONS: 100% rapid re-screening is an efficient alternative for reduction of cervical screening false negative rates. It also allowed to monitor the individual performance of members of the team.

    Background: Abnormal Pap smear consists of premalignant or malignant cervical lesions. Many of premalignant cervical lesions will never progress to invasive malignancy, or even may regress over the time. Thus, there is always a risk of overtreatment of patients with an abnormal Pap smear. A long-term follow-up of these patients can reveal final events associated with each subtype of abnormal Pap smear, and, therefore, help us to prevent unnecessary interventions. The aim of our study was to p...

  1. [Is the PAP smear era coming to an end?].

    2015-12-01

    After the discovery of the role human papilloma virus (HPV) plays in the development of cervical cancer we are witnesses to a change in the conception and interpretation of cervical cancer prevention processes. Primary prevention gained a new tool in the form of HPV vaccines. Secondary prevention, i.e. detection of cervical intraepithelial neoplasia (GIN), acquired a new diagnostic method--the HPV test. Studies were initiated in order to determine the usefulness of HPV tests in cervical cancer prevention and screening. They revealed that the DNA HPV test used in screening has higher sensitivity in CIN detection than PAP smear and that HPV-negative patients are better and longer protected against developing cervical cancer in comparison to women with normal PAP smear results. HPV tests also possess a predictive value, which detects women more susceptible to developing cervical cancer in the future. PAP smear does not have a predictive value. Instead, it only detects a presence or an absence of neoplasia at that particular time. These results clearly indicate that the era of classic PAP smear is indeed coming to an end, replaced by a new primary CIN screening tool--HPV test. The entire cervical cancer screening system must therefore be redefined and reorganized. PMID:26995946

    Full Text Available Background: Cervical cancer is one of the ten most frequent cancers in Turkey. It is well known that cervical cancer morbidity and mortality could be significantly reduced with an active cervical smear screening (Pap smear program. Aims: The aims of this study were: 1 to evaluate the knowledge and attitudes of women about cervical smear testing; 2 to establish a cervical smear screening program and to evaluate the cervical cytological abnormalities that were found; 3 to determine the applicability, limitations and effectiveness of this screening in a primary health care unit. Patients and Methods : A total of 332 married women were included in our study. We collected data concerning socio-demographic and fertility characteristics, and knowledge about Pap smear testing was determined through printed questionnaires. A gynecological examination and Pap smear screening was performed on every woman in our study group. Results: Over ninety percent of our study group had never heard of and had not undergone Pap smear screening before. Of the 332 smears evaluated, 328 (98.8% were accepted as normal, whereas epithelial cell anomalies were seen in 4 (1.2%, infection in 59 (17.7%, and reactive cell differences in 223 (67.2% of the smears. Conclusions: The frequency of epithelial cell anomalies in our study group was less than the frequencies reported from Western countries. Knowledge regarding cervical cancer and Pap smear screening was very low. Pap smears can be easily taken and evaluated through a chain built between the primary health care unit and laboratory, and this kind of screening intervention is easily accepted by the population served.

    The observed energy spectrum of ultra high energy cosmic rays (UHECR) is distorted by errors in the energy reconstruction. We estimate the UHECR spectrum at the Earth assuming it is originated from a cosmological flux. We then convolute this flux assuming a lognormal error in the energy. We show that if the standard deviation of the lognormal error distribution is equal or larger than 0.25, not only the shape but also the normalization of the measured energy spectra will be modified. As a consequence the GZK cutoff might be sufficiently smeared and as not to be seen. This result is independent of the power law of the cosmological flux. As a conclusion we show that in order to establish the presence or not of the GZK feature, not only more data is needed but also that the shape of the energy error distribution has to be known well.

    Full Text Available Aim: Cervical cancer amongst Nigerian women has been on the increase in the past decade, and is regarded as the second highest cause of cancer deaths among Nigerian women. This study was aimed at determining the prevalence, risk factors of HPV infection, and Papanicolaou smear pattern amongst a cohort of women attending the Gynaecology clinic of a tertiary health facility in Ido-Ekiti, South west Nigeria. Method: This was a cross-sectional study involving the screening of women between the ages of 15-64 years for cervical intraepithelial neoplasia using Papanicolaou smear staining technique and serological diagnosis using IgG enzyme linked immunosorbent assay kits. Respondents were selected through convenience sampling of subjects, while interviewer- administered questionnaire and clinical report form were also used to collect data, and data was analyzed using SPSS version 17. Results: Of the 200 blood samples examined for Human papillomavirus infection, 135 (67.5% were sero-positive while 65 (32.5% were sero-negative. For cervical cytology using Papanicolaou smear, 14 (7% were positive (had presence of cervical abnormality while 186 (93% were negative (had no cervical abnormality. Result showed a direct relationship between seropositivity, development of cervical intraepithelial neoplasia and Human papillomavirus infection. The risk factors for the development of HPV infection included age, type of marriage, parity, history of genital infection and tobacco usage. Non circumcision of male partner was also found to be a risk factor. Conclusion: The presence of abnormal cervical cytology and high level of serological positivity clearly showed why there is need for a holistic approach to the screening, vaccination methodologies and early detection of HPV infection in the country.

    Cervical smear material contains endo and exocervical cells, mucus and inflammative, immune cells in cases of pathology. Just not destroyed keratinocytes lay on the glass for microscopy. Liquid cytology supernatant apart other diagnostics could be used for photodiagnostic. The spectroscopic parameters suitable for Normal and HSIL cytology groups supernatant differentiation are demonstrated. The dried liquid PAP supernatant fractions—sediment and liquid were investigated. Excitation and emission matrices (EEM), supernatant fluorescence decay measured under 280 nm diode short pulse excitation and fluorescence spectroscopy by excitation with 355 nm laser light were analyzed. The differences between Normal and HSIL groups were statistically proven in the certain spectral regions. Fluorescence decay peculiarities show spectral regions consisting of few fluorophores. Obtained results on fluorescence differences in Normal and HSIL groups' supernatant shows the potency of photodiagnosis application in cervical screening.

    Full Text Available Cervical cancers form the second highest number of female cancers in Malaysia, imposing a substantial amount of cost burden on its management. However, an estimation of cost burden of abnormal smears, cervical pre-invasive and invasive diseases needs to be done to show how much spending has been allocated to the problem. An expert panel committee came up with the clinical pathway and management algorithm of  cervical pre invasive and invasive diseases from July-December 2006 Malaysia. An activity based costing for each clinical pathway was done. Results were converted to USD. The cost of managing pre-invasive cervical cancers stage is USD 420,150 (Range: USD 197,158-879,679. Management of invasive cancer (new cases costs USD 51,533,233.44 (Range: USD 32,405,399.69 - USD 129,014,768.40. The cost of managing existing cases is USD 17,005,966.87 (Range: USD 10,693,781.90 - USD  28,901,587.12. The total cost of managing cervical cancers by health care providers in a public setting is around USD 75,888,329.45 (Range: USD 48,083,804.60 - USD 48,083,804.60. The outcome of this study has shown that preventive modalities such as screening have only contributed to 10.3 % of the total management cost of cervical cancer. The major cost contribution (67% came from treatment of invasive cancer especially at more advanced stages of cancer, followed by treatment of existing cases (22% and lastly on pre-invasive disease (0.6%. This study revealed that proportion of preventive modality in this country was still low, and the major cost came from actual treatment cost of cervical cancer. Therefore, heightened public cervical cancer screening in the country is needed. (Med J Indones 2008; 17: 272-80Keywords: cervical cancers, pre invasive disease, HPV vaccination

    Full Text Available Background: Cervical cancer is the second most common cancer among women worldwide and is the leading cause of deaths in developing countries. Despite the strong evidence that cervical cancer screening results in decreased mortality from this disease, the uptake for cervical screening among Jamaican women remains low. Aims : This study was carried out to identify factors associated with Jamaican women′s decisions to screen for cervical cancer. Materials and Methods: Cross-sectional descriptive study of 403 women aged 19 years and older from Portland, Jamaica. An interviewer-administered questionnaire assessed the women′s cervical cancer screening history, as well as their knowledge, attitudes, and practices regarding the disease and screening. Results: Of the 403 women interviewed, 66% had a Papanicolaou (Pap smear and only 16% had a Pap test within the past year. Significant predicators of uptake of screening were being married, age, parity, discussing cancer with health provider, perception of consequences of not having a Pap smear, and knowing a person with cervical cancer. Women who did not know where to go for a Pap smear were 85% less likely to have been screened (prevalence odds ratio (POR: 0.15, 95% confidence interval (CI: 0.04, 0.52. Conclusions: This study showed suboptimal uptake of cervical cancer screening among Jamaican women. Multipronged approaches are needed to address barriers to screening, as well as identify and support conditions that encourage women′s use of reproductive health services, thereby reducing incidence and mortality rates from cervical cancer.

    Full Text Available BACKGROUND: Cervical intra - epithelial neoplasia (CIN and cervical cancer remain important health problems for women worldwide. It is largely a preventable disease that is characterized by a long lead time. The objective of this study was to determine the frequency of precancerous lesions of cervix by Pap smear screening. METHODS : A retrospective hospital based study was conducted at Department of Pathology, in a Tertiary Care Institute and associated hospital, Bhopal. Data was collected from the records of Pap’s smear testing done on 388 patients in years 2011 & 2012. Analysis was done by entering data in SPSS software and Chi - square test was applied to find statistical significance. RESULTS: Most common lesions on Pap’s smear was Low grade squamous intraepithelial les ion (LSIL in 104 (26.8% of cases and High grade squamous intraepithelial lesion (HSIL in 15 (3.9% of cases. 44 (11.3% were senile Atopic Changes, parasitic Infection in 27 (7% of cases and 2 (0.5% were carcinoma cervix cases. All the cervical lesion s were most common in age of 31 - 40 yrs. and were significantly associated with age. CONCLUSIONS: Pap’s smear examination information should be spread in community apart from hospitals. Especially the young women should be motivated for regular Pap’s smear. Pap’s smear is the single most important screening method for early detection of precancerous & cancerous cervical lesions

    Nuclei of the epithelial of Pap smear cells are important risk indicator of cervical cancers. Pathologist uses the changing of the area of the nuclei to determine whether cells are normal or abnormal. It means that having correct measurement of the area of nuclei is important on the pap smears assessment. Our paper present a novel approach to analyze the shape of nuclei in pap smear images and measuring the area of nuclei. We conducted a study to measure the area of nuclei automatically by calculating the number of pixels contained in each of the segmented nuclei. For comparison, we performed measurements of nuclei area using the ellipse area approximation. The result of the t-test confirmed that there were similarity between elliptical area approximation and automatic segmented nuclei-area at 0.5% level of significance.

Aims: To see whether the cytological pickup improves with the use of long tipped spatula. Setting and Design: Rurally based University Hospital; crossover study. Materials and Methods: Pap smear using Ayre spatula in 500 and with plastic narrow long tip (Szalay spatula in 500 clinic attending women was taken and analyzed. Crossover smears were taken with modified spatula in 163 and using Ayre spatula in 187 women after 2 weeks of initial smears. The same pathologist made cytological reporting for all smears and was unaware of the type of spatula used. Results: Smears from Ayre spatula had significantly higher reports of inadequate smears (94 of 500 vs. 68 of 500 for Ayre and Szalay, respectively; P = 0.032 and it remained so even after crossover (94 of 187 vs. 70 of 163 for Ayre and Szalay, respectively; P = 0.2. Cellular quality appeared better with smears taken using Szalay spatula, but the overall abnormal smear detection rate remained similar with either collection tool (χ2 = 1.5; P = 0.2. Conclusions: Proportion of satisfactory smears is higher when long tip plastic spatula is used for collection of sample.

    Conclusions: The umbrella cells may be mistaken for dysplastic cells originating in low grade squamous intraepithelial lesions lesions (LSILs due to their nuclear and cytoplasm sizes. Therefore, it is important to know the possibility of their appearance in the cervical smears, especially in post menopausal patients in order to avoid a false diagnosis of an intraepithelial lesion. It is unlikely that deeper cells of urothelium would be confused with high grade squamous intraepithelial lesion (HSIL cells. However, their presence might be a reason of mistake in the diagnosis. TCM is an under-recognized metaplastic phenomenon of the cervix and vagina, which is a mimicker of high-grade squamous intraepithelial lesion. The differential characteristic between umbrella cells, cells from TCM and the deeper urothelial cells, and LSIL and HSIL are detailed in the present paper.

    Cervical cancer is the fourth common cancer among women worldwide. Pap smear screening has resulted in deceasing incidence of cervical cancer in developed countries but low uptake of Pap smear screening among women in developing countries is still a public health challenge. The aim of this cross-sectional study was to assess the relationship between self-efficacy and timely uptake of Pap smear among Iranian women. A total of 580 married women referred to primary health care centers covered administratively by Shahid Beheshti University of Medical Sciences in Tehran were administered a questionnaire by trained staff. Data were analyzed with SPSS (version 16) software, using univariate and multivariate logistic regression. The mean age for participants was 33.1±8.8 years. There was a significant association between self-efficacy and Pap smear screening (PPap smear uptake (PPap smear uptake and level of self-efficacy (OR = 15.3 for intermediate and OR=7.4 for good level), duration of marriage (OR = 5.7 for 5-14 years and OR=10.4 for more than 15), age (OR =2.7 for 27-34 years and OR=7.4 for more than 35 years) and husband education level (OR=2.3 for more than 12 years of education). In multivariate analysis, significant associations persisted between Pap smear uptake and self-efficacy (OR = 23.8; 95% CI: 8.7, 65.5), duration of marriage (OR = 5.9; 95% CI: 2.8, 12.2), age (OR = 3.9; 95% CI: 1.2, 12.9) and husband's education (OR = 2.5; 95% CI: 2.0, 10.3). Efforts are needed to increase women's knowledge about cervical cancer and improve their self-efficacy and perceptions of the Pap smear screening in order to reduce cervical cancer incidence and mortality rates.

    Cervical cancer is preventable because the carcinogenesis is slow and there are opportunities to detect precancerous lesions by Papanicolaou (Pap) smears, colposcopy, or HPV DNA tests and to treat them by antimicrobials, surgery or cold CO2 vapourization. We have earlier reported on the chemopreventive potential of integrated treatment with antimicrobials therapy followed by a standardized oral Turmeric Oil (TO) extract upto 12 weeks in women who had persistent Low-grade Squamous Intra-epithelial Lesion (LSIL) in their Pap smears. In this communication we report their post-therapy follow up for 36 months (N = 18) with Pap smears. We were also able to follow up for 36 months control cases (N = 10) who had only standard therapy with antimicrobials. During 36 months of follow up none of the cases with integrated treatment, progressed to HSIL or cancer. Out of 15/18 cases which had a regression of Pap smear, all 15 remained free of LSIL from 6 to 36 months post-therapy showing persistent therapeutic effect of integrated therapy. In one case there was recurrence of LSIL in Pap smear, ten months post-therapy, which regressed to mild atypia after a second course of oral TO for 8 weeks. In the control group, persistence of LSIL after antimicrobials was observed in Pap smears in 5/10 cases when followed up by Pap smears up to 36 months. This preliminary report indicates some post-therapeutic benefit with integrative treatment as compared to the use of antimicrobials alone. A large scale controlled study is warranted. PMID:27475746

    Full Text Available The purpose of this study was to carry out a scanning electron microscopic (SEM analysis of the cleaning qualities and smear layer removal from root canal walls, instrumented and irrigated with 2.5% NaOCl, 2.0% chlorhexidine and saline solutions. Fifty extracted teeth were used in this study. All teeth were radiographed to determine the existence of a single canal. The crowns were cut at the cervical limit and the root canals were instrumented with K-type files up to size 45. During root canal preparation, irrigations were made with the different solutions being evaluated: Group 1: 2.5% NaOCl (10 roots; Group 2: 2.5% NaOCl and 17% EDTA for 2 minute (10 roots; Group 3: 2.0% chlorhexidine (10 roots; Group 4: 2.0% chlorhexidine and 17% EDTA for 2 minutes (10 roots; Group 5: saline solution (5 roots; Group 6: saline solution and 17% EDTA for 2 minutes (5 roots. After instrumentation, the canals were irrigated with each one of the solutions and the roots were cut in the buccolingual direction for SEM analysis, at the cervical, middle and apical thirds, to ascertain the presence or absence of smear layer and debris. SEM analysis was performed by three calibrated examiners and scores were submitted to Kruskal-Wallis test at the significance level of p = 5%. Results showed that the use of 17% EDTA decreased the smear layer significantly (p < 0.05 for all evaluated solutions in all thirds. When EDTA was not used, a significantly higher quantity of smear layer on the apical third was observed only in the NaOCl groups. The use of 17% EDTA was significant for debris removal except for the chlorhexidine groups. The following conclusion could be drawn: the use of 17% EDTA was necessary to enhance cleanness of the root canals.

Methods We studied 32 patients with MS and 17 without any neurologic disorder. Fractional anisotropy (FA, axial diffusivity (AD, radial diffusivity (RD and mean diffusivity (MD were calculated within regions of interest at C2 and C7 levels in the four columns of the spinal cord. Results At C2, FA value was decreased in MS patients. Besides, RD value was higher in MS than in controls. At C7, MD values were increased in MS. Conclusion The NASC in the right column of the cervical spinal cord showed abnormal FA, RD and MD values, which is possibly related to demyelination, since the FA abnormality was related to the RD and not to the AD.

    Full Text Available Abstract Background Anal smears are increasingly being used as a screening test for anal squamous intraepithelial lesions (ASILs. This study was undertaken to assess the usefulness and limitations of anal smears in screening for ASILs. Methods The cytomorphological features of 200 consecutive anal smears collected in liquid medium from 198 patients were studied and findings were correlated with results of surgical biopsies and/or repeat smears that became available for 71 patients within six months. Results Adequate cellularity was defined as an average of 6 or more nucleated squamous cells/hpf. A glandular/transitional component was not required for adequacy. Dysplastic cells, atypical parakeratotic cells and bi/multinucleated cells were frequent findings in ASIL while koilocytes were infrequent. Smears from LSIL cases most frequently showed mildly dysplastic and bi/multinucleate squamous cells followed by parakeratotic cells (PK, atypical parakeratotic cells (APK, and koilocytes. HSIL smears contained squamous cells with features of moderate/severe dysplasia and many APKs. Features of LSIL were also found in most HSIL smears. Conclusions In this study liquid based anal smears had a high sensitivity (98% for detection of ASIL but a low specificity (50% for predicting the severity of the abnormality in subsequent biopsy. Patients with cytologic diagnoses of ASC-US and LSIL had a significant risk (46–56% of HSIL at biopsy. We suggest that all patients with a diagnosis of ASC-US and above be recommended for high resolution anoscopy with biopsy.

All cervicovaginal smears were conventional Pap smear samples evaluated according to the 2001 Bethesda system.Results: There were 3.332 patients in total, whose smears showed no lesions in 3.125 patients. The mean age and number of parities of those patients were 37.34±11.25 and 4.78±3.28. There were 207 smears showing any lesions in cervix; ASC-US, ASC-H, LSIL, HSIL, AGC, squamous cell carcinoma and endocervical adenocarcinoma in 151 (72.94%; 16 (7.72%; 20 (9.66%; 8 (3.86%; 10 (4.83%; 1 (0.48% and 1 (0.48% patient, respectively. The mean age and the parities of the patients were 37.63±10.77 years and 4,74±2,92. Although there was no difference between the control and lesion groups, the parity and the age of patients who had ≥4 births in both the control and lesion groups were significantly higher than the patients with parities <4 births (p=0.000. There was no difference within the cervical lesion group comparing the ASC-US group with the total of the other lesions.Conclusion: High parity was one of the risk factor for having a lesion in uterine cervix in this population.

    International Nuclear Information System (INIS)

    To evaluate accuracy of intraoperative crush smears diagnosis of neurosurgical biopsies. One hundred, neurosurgical biopsies were received for intraoperative consultation over a period of one year. Clinical information regarding age, gender, history, and CT scan or MRI findings were recorded. Crush smears were prepared, fixed in 95% alcohol and stained with rapid haemotoxylin and eosin (H and E) stains. Diagnosis was categorized into inflammatory, benign and malignant tumours. Remaining tissue was fixed overnight in 10% formalin for histological sections. Permanent H and E sections were used as the gold standard. The average time required for intraoperative cytological diagnosis was 8 minutes. Out of 100 neurosurgical biopsies, crush smears of 94 were considered suitable for interpretation. There were 8 inflammatory, 41 benign and 41 malignant tumours, including 4 inconclusive. Eighty-four of the crush smears diagnosis agreed with the histological diagnosis. Overall diagnostic accuracy of crush smears was 93.3%. Diagnosis of inflammatory, benign and malignant tumours showed specificity of 98.7%, 96% and 94%, and a sensitivity of 70%, 97.5% and 95% respectively. Crush smears are useful in the intraoperative diagnosis of space occupying lesions of central nervous system. The crush smears cytology was found highly reliable, rapid and inexpensive mode of intraoperative diagnosis. (author)

    Background: The sensitivity of cervical cytology for detection of glandular lesions is reported to be low. We conducted this study to assess the diagnostic accuracy of cervical Papanicolaou (Pap) smears for uterine glandular lesions and to compare the diagnostic utility of conventional and liquid-based cytology (LBC) smears for glandular lesions. Materials and Methods: Archived histopathology records of all cases reported as endocervical and endometrial adenocarcinoma in the study period were identified and the available corresponding Pap smears (in preceding 1 year) were retrieved. In addition, the Pap smears reported as glandular cell abnormalities (GCA) during the same study period were retrieved. The overall prevalence of GCA, sensitivity, and specificity of Pap smears for the detection of GCA was calculated. The diagnostic accuracy of conventional and LBC smears for the diagnosis of GCA was also compared. Results: The prevalence of GCA in our study was 0.32%. The overall specificity of Pap smears for the diagnosis of GCA was 60.8%, this was not significantly different between conventional and LBC smears (P = 0.4). The overall sensitivity of Pap smears for the detection of GCA was 41.8%; LBC smears had significantly better sensitivity as compared to conventional smears for the detection of endometrial as compared to endocervical adenocarcinoma (P Pap smears is low. The specificity of Pap smears, for diagnosis of GCA, was found to be moderate. However, the overall sensitivity of Pap smears for the detection of GCA was low, though better for LBC as compared to conventional smears. PMID:27014363

    Full Text Available Background: A serious proportion of the patients with invasive cervical cancer can be women who have had abnormal smear findings known for at least 6 months. Aims: The aims of the study were to evaluate the cervical cytohistopathologic correlation in the population studied, and to discuss the acceptability of immediate histological verification for minor Papanicolaou smear abnormalities. Materials and Methods: A total of 443 patients who were admitted with abnormal smear results and had undergone immediate colposcopy, cervical biopsy and endocervical curretage in the gynecologic oncology clinic between the years of 2003-2009 were enrolled into the present retrospective study. One-way analysis of variance and independent t-tests were used to study the results. Results: The distribution of abnormal smear results were documented as 46.27%, 29.57%, 13.76%, 7.67%, 1.58%, 0.67%, and 0.45% for atypical squamous cells of undetermined significance (ASC-US, low-grade squamous intraepithelial lesion (LSIL, high-grade squamous intraepithelial lesion (HSIL, atypical squamous cells cannot exclude high-grade squamous intraepithelial lesion (ASC-H, squamous cell carcinoma (SCC, atypical glandular cell (AGC, and adenocarcinoma, respectively.

    Automation of the Pap-smear cervical screening method is highly desirable as it relieves tedium for the human operators, reduces cost and should increase accuracy and provide repeatability. We present here the design for a high-throughput optoelectronic system which forms the first stage of a two stage system to automate pap-smear screening. We use a mathematical morphological technique called the hit-or-miss transform to identify the suspicious areas on a pap-smear slide. This algorithm is implemented using a VanderLugt architecture and a time-sequential ANDing smart pixel array.

Descriptive statistics were used to analyse the data and chi-square testing found associations between categorical variables. Results: The majority of respondents (78.7%; n = 248 indicated that they had heard of cervical cancer and 62.9% (n = 198 knew about the Pap smear, with nurses and doctors being the primary source of information. Of the women who knew about the Pap smear, less than one-third had had a smear done, the main reason being fear of the procedure. Conclusion: The study provided evidence that women attending the specific HIV clinic were more knowledgeable about cervical cancer and screening than those of unknown HIV status involved in previous studies. Knowledge was still at a low level, especially when their exceptionally high risk was taken into account. Once again it was found that having knowledge did not necessarily mean having had a Pap smear, which remains a huge challenge in the prevention of cervical cancer.

  8. Pap smears for men: a vision of the future?

    BACKGROUND: Anal intraepithelial neoplasia (AIN) rarely receives as much publicity as its neighbouring orifice, the cervix. As in the cervix, intraepithelial neoplasias are precursors to cancer in the anal canal. AIN and cervical interstitial neoplasia (CIN) undergo dysplasia as a consequence of human papillomavirus (HPV) infection. Since the advent of screening with the Pap smear in CIN, cervical cancer has plummeted to a fifth of its initial incidence. Anal cancer, however, has been rising, with a predilection for human immunodeficiency virus-infected men. HPV causes a squamous epithelial dysplasia and converts healthy tissue into AINs of increasing severity until anal cancer manifests. CLINICAL CASE: This article describes a clinical case of anogenital HPV infection refractory to medical and surgical therapy. It also describes an effective surgical excision technique associated with a good cosmetic outcome. CONCLUSIONS: The paper concludes by briefly discussing the implications of a national screening programme against AIN in the future.

    Full Text Available AIM: Aim of our study to analyze the prevalence of premalignant lesion based on Pap smear and liquid based cytology in patients of bad cervix. OBJECTIVE: To compare sensitivity and specificity of two methods for screening of bad cervix and to know IDR (increase detection rate of cervical cancer by conventional Pap smear and liquid based cytology. MATERIAL AND METHOD: 200 women attending Gynaecology OPD were random selection on the basis of inclusion criteria. All 200 selected women were subjected for down staging through per speculum examination for identification of bad cervix. Pap smears of all 200 selected women were taken and ensured that no local douche, antiseptic cream and no local internal examination was done on the day of test. The prepared smears were then stained according to Papanicolaou's technique. Liquid based cytology smears preparing by using cervical brush 1-1.5cm were inserted into the cervical os until the large outer bristles of the brush touch ectocervix. Data collected for sociodemographic, parity, down staging clinical examination Pap smear and LBC was organised, interpreted and analysis on appropriate statistical software. P value < 0.05 is considered significant RESULT: Analysis revealed that the maximum number of women in our study are from middle age group(31-40yrs, low socioeconomic status, married before 18 yrs, multipara, do not use any contraceptive, uneducated, urban, Muslim population.in this study more abnormal smear is seen in LBC as compared to pap smear. Sensitivity and specificity for LBC is more as compare to pap smear. CONCLUSION: In low resource setting like ours were facilities for radiology, chemo- radiotherapy and supportive care are limited or unavailable. It is important to identify which resources fill healthcare need most effectively and to consider alternative approaches, LBC is strongly advocated in the best interest of public health, by improving the quality of the sample and reducing the

    The aim of this study is to analysis of survival and recurrence rates of the uterine cervical carcinoma patients whom received the radiation therapy respectively. The prognostic factors, such as Papanicolaou (Pap) smear, carcinoembriogenic antigen (CEA) and squamous cell carcinoma (SCC) antigen has been studied. From January 1981 to December 1998, eight-hundred twenty-seven uterine cervical cancer patients were treated with radiation therapy. All of the patients were divided into two groups: the radiation therapy only (521 patients) group and the postoperative radiation therapy (326 patients) group. The age, treatment modality, clinical stage, histopathology, recurrence, follow-up Pap smears, CEA and see antigen were used as parameters for the evaluation. The prognostic factors such as survival and recurrence rates were performed with the Kaplan-Meier method and the Cox hazard model, respectively. Median fallow-up was 38.6 months. On the radiation therapy only group, 314 patients (60%) achieved complete response (CR), 47 patients (9%) showed local recurrence (LR), 78 patients (15%) developed distant metastasis (DM). On the postoperative radiation therapy group, showed 276 patients (85%) CR, 8 patients (2%) LR, 37 patients (11%) DM. The 5-year survival and recurrence rates was evaluated for all parameters. The statistically significant factors for the survival rate in univariate analysis were clinical stage (p=0.00001), treatment modality (p=0.0010), recurrence (p=0.0001), Pap smear (p=0.0329), CEA (p=0.0001) and SCC antigen (p=0.0001). This study indicated that after treatment, the follow-up studies of Pap smear, CEA and SCC antigen were significant parameter and prediction factors for the survival and recurrence of the uterine cervical carcinoma.

    Full Text Available Abstract Background The incidence of invasive cervical cancer in HIV-positive women is higher than in the general population. There is evidence that HIV-positive women do not participate sufficiently in cervical cancer screening in Italy, where cervical cancer is more than 10-fold higher in women with AIDS than in the general population. The aim of the present study was to evaluate the history of Pap-smear in HIV-positive women in Italy in recent years. We also examined the sociodemographic, clinical, and organizational factors associated with adherence to cervical cancer screening. Methods A cross-sectional study was conducted between July 2006 and June 2007 in Emilia-Romagna region (Northern Italy. All HIV-positive women who received a follow-up visit in one of the 10 regional infectivology units were invited to participate. History of Pap-smear, including abnormal smears and subsequent treatment, was investigated through a self-administered anonymous questionnaire. The association between lack of Pap-smear in the year preceding the interview and selected characteristics was assessed by means of odds ratios (OR and 95% confidence intervals adjusted for study centre and age. Results A total of 1,002 HIV-positive women were interviewed. Nine percent reported no history of Pap-smear, and 39% had no Pap-smear in the year prior to the date of questionnaire (last year. The lack of Pap-smear in the last year was significantly associated with age Three hundred five (34% women reported a previous abnormal Pap-smear, and of the 178 (58% referred for treatment, 97% complied. Conclusions In recent years the self-reported history of Pap-smear in HIV-positive women, in some public clinics in Italy, is higher than previously reported, but further efforts are required to make sure cervical cancer screening is accessible to all HIV-positive women.

    Full Text Available The purpose of the present study was to evaluate the sexual transmission of GBV-C/HGV, through RNA detection in cervicovaginal smears. Therefore the GBV-C/HGV RNA in cervicovaginal smears from apparently healthy women was investigated using routine proceedings for prophylactic screening to cervical cancer. GBV-C/HGV RNA was detected by reverse transcriptase and polymerase chain reaction (RT-PCR. Only one woman presented co-infection with human papilloma virus (HPV. The GBV-C/HGV RNA was detected in 13/73 (17.57% healthy women and it's prevalence in participating women between 28-43 years old was 53.85%. No association was found with GBV-C/HGV for the age of first sexual intercourse and number of pregnancies. In GBV-C/HGV RNA positive women, 69.23% were married. In conclusion, the present findings show that cervical and vaginal specimens could contain the GBV-C/HGV RNA.O objetivo do presente estudo foi avaliar a transmissão sexual de GBV-C/HBV, através da detecção do RNA viral em raspados cérvico-vaginais. Portanto, a presença do RNA GBV-C/HGV foi investigada em raspados cérvico-vaginais em mulheres aparentemente saudáveis que realizaram exames preventivos para câncer cervical. GBV-C/HGV RNA foi detectado por reação de transcriptase reversa e reação em cadeia da polimerase (RT-PCR. Apenas uma mulher apresentou a co-infecção com o papiloma vírus humano (HPV. O RNA GBV-C/HGV foi detectado em 13/73 (17,57% mulheres saudáveis e sua prevalência entre participantes da idade de 28-43 anos foi de 53,85%. Não foi observada relação entre a presença do RNA GBV-C/HGV com a idade de primeira relação sexual, nem com o número de gestações. Entre as mulheres que apresentavam o RNA viral, 69,23% eram casadas. O presente estudo demonstrou que secreções cérvico-vaginais podem conter o RNA viral GBV-C/HBV.

    Full Text Available Aim: In this trial, we evaluated women’s knowledge and behavior concerning the Pap smear test. Material and Method: Women attending to the family medicine outpatient clinic in between April 1 to May 30 irrespective of their complaints included in the study in Dogansehir, Malatya, Turkey. Sociodemographic data form was filled by trained personnel. Questions regarding whether they heard about the Pap smear test, have ever taken it, if not what were the reasons, what are the indications of the Pap smear test were asked. 139 women accepted to participate in the study. 46,8% had heard and 54,2 % didn’t hear about the Pap smear test. The source of information was 57% from health professionals 26% from the media, and 14% from the neighbors. Those who were informed about the Pap smear test from health professionals undertook it more than others. Media was the second effective source and neighbors were ineffective in context to Pap smear test being done Results: As a result preventive medicine has a distinct position in the primary care. Cervical malignancy of the urogenital tract is one of the rare preventable cancers by screening tests. In the primary care set up every effort should be supported in order to improve the awareness of women particularly who are at the risk group.

    Population cervical screening programmes are necessary for meaningfully reducing cervical cancer morbidity and mortality. Because of the high incidence of cervical cancer in South Africa, the need for a national screening programme has become evident. The success of such a programme will depend on, among others, the level of cervical cancer awareness among the target population, and their willingness to utilise cytological services and to comply with treatment and follow up protocols. We conducted a survey among female university students, as an elite group of women, to determine their level of cervical cancer awareness and the prevalence of the major risk factors for cervical cancer among them, their rate of utilisation of existing Pap smear services, and their attitudes to Pap smears in general. The majority of respondents were young, single (93.0%) and sexually active (86.9%,) having initiated sexual activity at a mean age of 17.27 +/- 2.18 years. There was a high prevalence of the major risk factors for cervical cancer among the respondents, and these included initiation of coitus before 18 years (53.3%), multiple sexual partners (73.6%), male partner with other partners (37.7%), and previous history of sexually transmitted diseases (42.2%) and vulval warts (4.7%). Their overall knowledge of cervical cancer was poor, although the majority of respondents were able to identify the major risk factors from a given list. This level of awareness of cervical cancer risk factors, however, did not translate into appreciation of personal risk of cervical cancer, safer sex practices or utilisation of Pap smear services. In conclusion, this elite group of women is at a high risk of cervical cancer and would benefit from cervical screening programmes. This would have to be coupled with measures to increase the level of awareness and knowledge of cervical cancer and its prevention. PMID:9803633

We aimed to determine women’s knowledge,attitudes and practice towards Pap smear and barriers for the screening in a public hospital.Materials and methods: This study, was carried out on 350 outpatient married women reffering for avisit at the clinics of the Alzahra educational hospital, Rasht- Iran, 2011. A questionnaire includingdemographic characteristics (24 questions, knowledge (14 questions, attitudes (11 statments andpractice (10 questions towards Pap smear was completed by interview with the women. The data wereanalyzed using SPSS ver.13.Results: Mean age of participants was 32 (SD 12 years. Of the respondents, only 44.3% were aware ofthe Pap smear and 27.1% had had it at least once in their life. The most common reason for having thetest was physicians’ or other health workers’ advise and for not having the test was no recommendationby health providers and lack of knowledge about Pap smear. Embarrassing, fear of the test result oreconomic problems mentioned by only 12 (4.2% as the main barrier. Mean (±SD knowledge score ofthe women who had heard about the Pap smear was 59.4 (24.3 and attitudes score of all participantswas 48.5 (11.6 from possible range score of 0-100. Women with a history of Pap smear had had higherawareness and attitudes score.Conclusion: The knowledge and practice of the women was inadequate and need to be promoted.Considering the main reason mentioned by the participants for not having the test, all health providersshould educate and encourage women to do regular Pap smear.

    This study was conducted retrospectively at the Queen Elizabeth Hospital and a private laboratory in Barbados to determine the types of epithelial abnormalities in cervico-vaginal Papanicolaou (Pap)-stained smears, and their clinical implications in Barbadian girls, 18 years and under, during the five-year period January 1995 to December 1999. Two hundred and sixty-five Pap smears from 236 patients were examined and the gynaecological history, initial and repeat Pap smear diagnoses, and histology reports of these patients were analyzed. Of the 236 first-visit smears, 94 (39.8%) were abnormal with 36 (15.3%) displaying cytologic features of squamous intra-epithelial lesions (SIL), (33 low grade and 3 high grade). A diagnosis of atypical squamous cells of undetermined significance (ASCUS) was reported in the remaining 58 (24.5%) abnormal smears, of which 35 (60.3%) were suspected to be related to human papillomavirus (HPV) infection. Twenty-two (23.4%) of these 94 patients, who had abnormal smears of either ASCUS or low grade squamous intra-epithelial lesions (LSIL) were re-evaluated within six to twelve months of the initial abnormal Pap smear diagnosis. Eight of these 22 patients (36.4%) had histological diagnosis of LSIL inclusive of cervical intra-epithelial neoplasia grade 1 (CIN 1) and condylomata. High-risk HPV DNA types were detected in two of these eight patients (25%). The study confirms that sexually active teenage girls are at risk of developing SIL and high-risk HPV infection. Screening of sexually active teenaged girls by Pap smears followed by other appropriate investigative procedures is recommended. PMID:12089874

    In the attempt to prevent cervical cancer, various preventive measures have been instituted, notable among which is the pap smear test, which fulfills the function of early detection of cancer cells or their precursors. Therefore, the objective was to investigate the discourse on the knowledge, feelings and expectations of women regarding the pap smear test. This is an exploratory qualitative approach, conducted with ten users of a Integrated Family Health Unit in the city of João Pessoa in the State of Paraíba. Data collection was conducted through recorded interviews in April 2011. Eight core ideas were identified: prevention of disease; self-motivated search, search recommended by another person; sense of shame and embarrassment, sensation of pain, feeling of satisfaction; conversations during the examination and exchange of knowledge about women's health. Based on the reports, there are many difficulties to be overcome to ensure greater adherence of women to the pap smear test. PMID:23896912

    Conventional Papanicolaou smear method is still commonly used for cervical cancer screening in Japan, despite the liquid-based cytology (LBC) that has become a global tendency in the world recently. One of the obstacles in the way of popularization of this method seems to be the confusion as to diagnosis upon cervical glandular lesions. We performed comparison study between LBC and conventional Papanicolaou smear about cytological diagnosis using split-sample method in 4522 patients. In 13 ca...

    2016-03-01

    There has been a marked decrease in the incidence of cervical cancer thanks to cytological screening with the Pap smear test. In Belgium, this screening is rather opportunistic. Over 39% of Belgian women between 25 and 64 years of age are never or only rarely screened by cytological tests. Moreover, there is an excess use of Pap smears because of women who rely on their yearly cervical smear and because many Pap smears are obtained from women beyond the target age range of 25 to 64 years. Sexually active adolescents are increasingly being recognized as a population distinct from adult women. They are at a high risk of acquiring the human papillomavirus (HPV), but most infections and cervical intraepithelial lesions caused by HPV are efficiently cleared by the immune system. We present a description of cervical cancer screening in Belgium using the database of the National Health Insurance Institute (RIZIV/INAMI) and the Belgian Health Care Knowledge Centre (KCE). We describe why elimination of Pap testing in the adolescent population reduces costs and harms without increasing cervical cancer rates. Expectant management, education on the risk factors for cervical cancer and HPV persistence, and HPV vaccination are very important in adolescents and young adults. PMID:25812038

    Results: The present study was conducted over a period of 6 months among 212 patients age of 18-60 years screened. Positive results obtained from cytology were 26, VIA was positive in 28 women. Cervical biopsy was done in 34 women who had positive results by either test. Histology in 31 cases was suggestive of cervical intraepithelial carcinoma (CIN. Conclusions: VIA, though less specific has comparable sensitivity to Pap smear and may be used as a primary screening tool for cervical cancer. In combination both the tests have a higher predictive accuracy. [Int J Res Med Sci 2015; 3(9.000: 2382-2385

    Full Text Available Infection, coinfection and type-specific human papillomavirus (HPV distribution was evaluated in human immunodeficiency virus (HIV-positive women from paired cervical and urine samples. Paired cervical and urine samples (n = 204 were taken from HIV-positive women for identifying HPV-DNA presence by using polymerase chain reaction (PCR with three generic primer sets (GP5+/6+, MY09/11 and pU1M/2R. HPV-positive samples were typed for six high-risk HPV (HR-HPV (HPV-16, -18, -31, -33, -45 and -58 and two low-risk (LR-HPV (HPV-6/11 types. Agreement between paired sample results and diagnostic performance was evaluated. HPV infection prevalence was 70.6% in cervical and 63.2% in urine samples. HPV-16 was the most prevalent HPV type in both types of sample (66.7% in cervical samples and 62.0% in urine followed by HPV-31(47.2% in cervical samples and HPV-58 (35.7% in urine samples. There was 55.4% coinfection (infection by more than one type of HPV in cervical samples and 40.2% in urine samples. Abnormal Papanicolau smears were observed in 25.3% of the women, presenting significant association with HPV-DNA being identified in urine samples. There was poor agreement of cervical and urine sample results in generic and type-specific detection of HPV. Urine samples provided the best diagnosis when taking cytological findings as reference. In conclusion including urine samples could be a good strategy for ensuring adherence to screening programs aimed at reducing the impact of cervical cancer, since this sample is easy to obtain and showed good diagnostic performance.

    INTRODUCTION: A reason for not recommending subtotal hysterectomy is the risk of cervical pathology. We aimed to evaluate cervical cancer screening and to describe cervical pathology after subtotal and total hysterectomy for benign indications. METHODS: Data regarding adherence to screening.......7% were not screened. We found a minimum of one abnormal test in 28 (10.8%) after subtotal hysterectomy and one after total hysterectomy. No cervical cancers were found. CONCLUSIONS: Adherence to cervical cancer screening after subtotal hysterectomy in a Danish population is suboptimal and some patients...... have unnecessary tests performed after total hysterectomy. Clarification of the use of cervical/vaginal smears after hysterectomy is needed to identify women at risk of cervical dysplasia or cancer.

  15. Clay smear: Review of mechanisms and applications

    2016-05-01

    Clay smear is a collection of fault processes and resulting fault structures that form when normal faults deform layered sedimentary sections. These elusive structures have attracted deep interest from researchers interested in subsurface fluid flow, particularly in the oil and gas industry. In the four decades since the association between clay-smear structures and oil and gas accumulations was introduced, there has been extensive research into the fault processes that create clay smear and the resulting effects of that clay smear on fluid flow. We undertake a critical review of the literature associated with outcrop studies, laboratory and numerical modeling, and subsurface field studies of clay smear and propose a comprehensive summary that encompasses all of these elements. Important fault processes that contribute to clay smear are defined in the context of the ratio of rock strength and in situ effective stresses, the geometric evolution of fault systems, and the composition of the faulted section. We find that although there has been progress in all avenues pursued, progress has been uneven, and the processes that disrupt clay smears are mostly overlooked. We highlight those research areas that we think will yield the greatest benefit and suggest that taking these emerging results within a more process-based framework presented here will lead to a new generation of clay smear models.

  16. Locally-smeared operator product expansions

    CERN Document Server

    Monahan, Christopher

    2014-01-01

    We propose a "locally-smeared Operator Product Expansion" (sOPE) to decompose non-local operators in terms of a basis of locally-smeared operators. The sOPE formally connects nonperturbative matrix elements of smeared degrees of freedom, determined numerically using the gradient flow, to non-local operators in the continuum. The nonperturbative matrix elements do not suffer from power-divergent mixing on the lattice, provided the smearing scale is kept fixed in the continuum limit. The presence of this smearing scale prevents a simple connection to the standard operator product expansion and therefore requires the construction of a two-scale formalism. We demonstrate the feasibility of our approach using the example of real scalar field theory.

  17. Analysis of digitized cervical images to detect cervical neoplasia

    2004-05-01

    Cervical cancer is the second most common malignancy in women worldwide. If diagnosed in the premalignant stage, cure is invariably assured. Although the Papanicolaou (Pap) smear has significantly reduced the incidence of cervical cancer where implemented, the test is only moderately sensitive, highly subjective and skilled-labor intensive. Newer optical screening tests (cervicography, direct visual inspection and speculoscopy), including fluorescent and reflective spectroscopy, are fraught with certain weaknesses. Yet, the integration of optical probes for the detection and discrimination of cervical neoplasia with automated image analysis methods may provide an effective screening tool for early detection of cervical cancer, particularly in resource poor nations. Investigative studies are needed to validate the potential for automated classification and recognition algorithms. By applying image analysis techniques for registration, segmentation, pattern recognition, and classification, cervical neoplasia may be reliably discriminated from normal epithelium. The National Cancer Institute (NCI), in cooperation with the National Library of Medicine (NLM), has embarked on a program to begin this and other similar investigative studies.

    Indigenous Australian women have much higher incidence of cervical cancer compared to non-Indigenous women. Despite an organised cervical screening program introduced 25 years ago, a paucity of Indigenous-identified data in Pap Smear Registers remains. Prevalence of cervical abnormalities detected among the screened Indigenous population has not previously been reported. We conducted a retrospective cohort study of population-based linked health records for 1,334,795 female Queensland residents aged 20–69 years who had one or more Pap smears during 2000–2011; from linked hospital records 23,483 were identified as Indigenous. Prevalence was calculated separately for Indigenous and non-Indigenous women, for cytology-detected low-grade (cLGA) and high-grade abnormalities (cHGA), and histologically confirmed high-grade abnormalities (hHGA). Odds ratios (OR) were estimated from logistic regression analysis. In 2010–2011 the prevalence of hHGA among Indigenous women (16.6 per 1000 women screened, 95% confidence interval [CI] 14.6–18.9) was twice that of non-Indigenous women (7.5 per 1000 women screened, CI 7.3–7.7). Adjusted for age, area-level disadvantage and place of residence, Indigenous women had higher prevalence of cLGA (OR 1.4, CI 1.3–1.4), cHGA (OR 2.2, CI 2.1–2.3) and hHGA (OR 2.0, CI 1.9–2.1). Our findings show that Indigenous women recorded on the Pap Smear Register have much higher prevalence for cLGA, cHGA and hHGA compared to non-Indigenous women. The renewed cervical screening program, to be implemented in 2017, offers opportunities to reduce the burden of abnormalities and invasive cancer among Indigenous women and address long-standing data deficiencies.

    Cytologic screening has been widely used for controlling the prevalence of cervical cancer. Errors from sampling, screening and interpretation, still concealed some unpleasant results. This study aims at designing a cellular image analysis system based on feasible and available software and hardware for a routine cytologic laboratory. Totally 1814 cellular images from the liquid-based cervical smears with Papanicolaou stain in 100x, 200x, and 400x magnification were captured by a digital camera. Cell images were reviewed by pathologic experts with peer agreement and only 503 images were selected for further study. The images were divided into 4 diagnostic categories. A PC-based cellular image analysis system (PCCIA) was developed for computing morphometric parameters. Then support vector machine (SVM) was used to classify signature patterns. The results show that the selected 13 morphometric parameters can be used to correctly differentiate the dysplastic cells from the normal cells (p<0.001). Additionally, SVM classifier has been demonstrated to be able to achieve a high accuracy for cellular classification. In conclusion, the proposed system provides a feasible and effective tool for the evaluation of gynecologic cytologic specimens.

    The aim of this study was to analyze the correlation between the first diagnosis of high-grade Vaginal Intraepithelial Neoplasia (HG-VaIN: VaIN 2-VaIN 3) and the cytological abnormalities on the referral pap smear.All the women with histological diagnosis of HG-VaIN consecutively referred to the Gynecological Oncology Unit of the Aviano National Cancer Institute (Aviano, Italy) from January 1991 to April 2014 and with a pap smear performed in the 3 months before the diagnosis were considered, and an observational cohort study was performed.A total of 87 women with diagnosis of HG-VaIN were identified. Major cytological abnormalities (HSIL and ASC-H) on the referral pap smear were significantly more frequent than lesser abnormalities (ASC-US and LSIL) in postmenopausal women (64.9% vs 36.7%, P = 0.02) and in women with a previous diagnosis of HPV-related cervical preinvasive or invasive lesions (70.5% vs 39.5%, P = 0.01). Diagnosis of VaIN 3 was preceded by major cytological abnormalities in most of the cases (72.7% vs 27.3%, P diagnosis of HG-VaIN can be preceded by different abnormalities on referral pap smear. Major abnormalities are usually reported in postmenopausal women and in women with previous cervical HPV-related disease. However, ASC-US or LSIL do not exclude HG-VaIN, especially VaIN2. An accurate examination of the whole vaginal walls (or vaginal vault) must be performed in all the women who underwent colposcopy for an abnormal pap smear, and a biopsy of all suspicious areas is mandatory.

    Full Text Available Conventional Papanicolaou smear method is still commonly used for cervical cancer screening in Japan, despite the liquid-based cytology (LBC that has become a global tendency in the world recently. One of the obstacles in the way of popularization of this method seems to be the confusion as to diagnosis upon cervical glandular lesions. We performed comparison study between LBC and conventional Papanicolaou smear about cytological diagnosis using split-sample method in 4522 patients. In 13 cases analyses, which were reported with either AGC or adenocarcinoma by either method, LBC tends to be milder than that by conventional smear, however, the credibility of LBC is considered to be near to that of conventional smear with regard to screening for glandular abnormalities. These results indicate that cervical cancer screening should shift to LBC under the enough experience and appropriate dealing with the cytological diagnosis.

    Full Text Available Ditsapelo M McFarland College of Nursing and Public Health, Adelphi University, Garden City, NY, USA Purpose: Papanicolaou (Pap smear services are available in most urban areas in Botswana. Yet most women in such areas do not screen regularly for cancer of the cervix. The purpose of this article is to present findings on the associations of demographic variables and Health Belief Model constructs with Pap smear screening among urban women in Botswana. Sample and methods: The study included a convenience sample of 353 asymptomatic women aged 30 years and older who were living in Gaborone, Botswana. Data were collected using a demographic questionnaire and items of the Health Belief Model. Data analysis included descriptive statistics for demographic variables and bivariate and ordinal (logit regression to determine the associations of demographic variables. Results: Having health insurance and having a regular health care provider were significant predictors of whether or not women had a Pap smear. Women with health insurance were more likely to have had a Pap smear test than women without health insurance (91% vs 36%. Similarly, women who had a regular health care provider were more likely to have had a Pap smear test than women without a regular health care provider (94% vs 42%. Major barriers to screening included what was described as "laziness" for women who had ever had a Pap smear (57% and limited information about Pap smear screening for women who had never had a Pap smear (44%. Conclusion: There is a need for more information about the importance of the Pap smear test and for increased access to screening services in Botswana.

    A hyperspectral imaging spectrograph has been used to measure the fluorescence and reflectance of cervical tissue in vivo. The instrument was employed in a clinical trial in Vilnius, Lithuania, where 111 patients were examined. The patients were initially screened by Pap smear, examined by colposcopy and a tissue sampling procedure was performed. Detailed histopathological assessments were performed on the biopsies, and these assessments were correlated with spectra and images. The results of the spectroscopic investigations show that different tissue types within one biopsy region exhibit different spectral signatures. A spectral analysis of the entire image localizes dysplastic regions in both fluorescence and reflectance, suggesting that the hyperspectral imaging technique is useful in the management of cervical malignancies.

    Cervical radiculopathy is a common clinical scenario. Patients with radiculopathy typically present with neck pain, arm pain, or both. We review the epidemiology of cervical radiculopathy and discuss the diagnosis of this condition. This includes an overview of the pertinent findings on the patient history and physical examination. We also discuss relevant clinical syndromes that must be considered in the differential diagnosis including peripheral nerve entrapment syndromes and shoulder pathology. The natural history of cervical radiculopathy is reviewed and options for management are discussed. These options include conservative management, non-operative modalities such as physical therapy, steroid injections, and operative intervention. While the exact indications for surgical intervention have not yet been elucidated, we provide an overview of the available literature regarding indications and discuss the timing of intervention. The surgical outcomes of anterior cervical decompression and fusion (ACDF), cervical disc arthroplasty (CDA), and posterior cervical foraminotomy (PCF) are discussed. PMID:27250042

    2004-07-01

    Efficient computer-aided cervical cancer detection can improve both the accuracy and the productivity of cytotechnologists and pathologists. Nuclear segmentation is essential to automated screening, and is still a challenge. We propose and demonstrate a novel approach to improving segmentation performance by multispectral imaging followed by unsupervised nuclear segmentation relying on selecting a useful subset of spectral or derived image features. In the absence of prior knowledge, feature selection can be negatively affected by the bias, present in most unsupervised segmentation, to erroneously segment out small objects, yielding ill-balanced class samples. To address this issue, we first introduce a new measurement, Criterion Vector (CV), measuring the distances between the segmentation result and the original data. This efficiently reduces the bias generated by feature selection. Second, we apply a novel recursive feature selection scheme, to generate a new feature subset based on the corresponding CV, ensuring that the correct part of the initial segmentation results is used to obtain better feature subsets. We studied the speed and accuracy of our two-step algorithm in analyzing a number of multispectral Pap smear image sets. The results show high accuracy of segmentation, as well as great reduction of spectral redundancy. The nuclear segmentation accuracy can reach over 90%, by selecting as few as 4 distinct spectra out of 30.

    Full Text Available Introduction: In the patients with smear-positive pulmonary tuberculosis (TB bacteriologic assessment of sputum for detection of acid bacilli (AFB Has essential role. This evaluation is accomplished by direct sputum smear & sputum culture. These examinations must be done in regular and preferably monthly after beginning of treatment. These tests have two important aims, including, determining of treatment efficacy & duration of isolation."nMethods and Materials: Most of the studies have that classic six month regimen led to sputum smear conversion & negative sputum culture in 85% of patient. This treatment regimen has two phases, including, attack phase and maintenance phase. In the attack phase we use four drugs, including, Isoniazid (INH, Rifampin (RMP, Pyrazinamide (PZA and Ethambutol (EMB for the first 2 months and if necessary until the end of third month. In the maintenance phase we use INH and Rif for the remaining of treatment course. The main objectives of this study were to determine the time needed for smear conversion and assessment of probable factors which may influence the smear conversion until 4 months after beginning of therapy. The factors that were assessed, were, Age, nationality, sex, clinical symptoms, underlying diseases, chest radiography (number of cavities, smoking, drug abuse and concentration of AF13 in the sputum Generally, we did this cross sectional study on the patient's records, who had been observed in Imam Khomeni Hospital, west health service center and masih daneshvary hospital between."nResults: This study showed that from totally 218 patients, 138(74.6% patients had sputum conversion at the first 2 months of treatment and until the end of 3rd & 4th month this rate reached to 83.3% respectively. So in the end of fourth month only 32(14.7% patients did not show sputum smear conversion. On the other hand this study showed that two factors including presence of cavities in chest radiography

    Full Text Available Background: Female genital schistosomiasis (FGS is a tissue reaction to lodged ova of Schistosoma haematobium in the genital mucosa. Lesions can make the mucosa friable and prone to bleeding and discharge. Women with FGS may have an increased risk of HIV acquisition, and FGS may act as a cofactor in the development of cervical cancer. Objectives: To explore cytology as a method for diagnosing FGS and to discuss the diagnostic challenges in low-resource rural areas. The correlation between FGS and squamous cell atypia (SCA is also explored and discussed. Cytology results are compared to Schistosoma polymerase chain reaction (PCR in vaginal lavage and urine and in urine microscopy. Materials and Methods: In a clinical study, 394 women aged between 16 and 23 years from rural high schools in KwaZulu-Natal, South Africa, underwent structured interviews and the following laboratory tests: Cytology Papanicolaou (Pap smears for S. haematobium ova and cervical SCA, real-time PCR for Schistosoma-specific DNA in vaginal lavage and urine samples, and urine microscopy for the presence of S. haematobium ova. Results: In Pap smears, S. haematobium ova were detected in 8/394 (2.0%. SCA was found in 107/394 (27.1%, seven of these had high-grade squamous intraepithelial lesion (HSIL. Schistosoma specific DNA was detected in 38/394 (9.6% of vaginal lavages and in 91/394 (23.0% of urines. Ova were found microscopically in 78/394 (19.7% of urines. Conclusion: Schistosoma PCR on lavage was a better way to diagnose FGS compared to cytology. There was a significant association between S. haematobium ova in Pap smears and the other diagnostic methods. In low-resource Schistosoma-endemic areas, it is important that cytology screeners are aware of diagnostic challenges in the identification of schistosomiasis in addition to the cytological diagnosis of SCA. Importantly, in this study, three of eight urines were negative but showed Schistosoma ova in their Pap smear, and

    Persistent infection with high-risk types of human papillomavirus(HPV) is known to cause cervical cancer; however,additional genetic and epigenetic alterations are required for progression from precancerous disease to invasive cancer.DNA methylation is an early and frequent molecular alteration in cervical carcinogenesis.In this review,we summarize DNA methylation within the HPV genome and human genome and identify its clinical implications.Methylation of the HPV long control region (LCR) and L1 gene is common during cervical carcinogenesis and increases with the severity of the cervical neoplasm.The L1 gene of HPV16 and HPV18 is consistently hypermethylated in invasive cervical cancers and can potentially be used as a clinical marker of cancer progression.Moreover,promoters of tumor suppressor genes (TSGs) involved in many cellular pathways are methylated in cervical precursors and invasive cancers.Some are associated with squamous cell carcinomas,and others are associated with adenocarcinomas.Identification of methylated TSGs in Pap smear could be an adjuvant test in cervical cancer screening for triage of women with high-risk HPV,atypical squamous cells of undetermined significance,or low grade squamous intraepithelial lesion (LSIL).However,consistent panels must be validated for this approach to be translated to the clinic.Furthermore,reversion of methylated TSGs using demethylating drugs may be an alternative anticancer treatment,but demethylating drugs without toxic carcinogenic and mutagenic properties must be identified and validated.

    Full Text Available Introduction:Cervical cancer is the second most common cancer affecting Malaysian women. Despite the implementation of pap smear screening, many women are still diagnosed only in the advanced stage of cervical cancer. This could partly be due to failure of detection of its precursor lesions; hence the need to search for novel biomarkers to assist in the screening and diagnosis of cervical neoplasia. This study aims to determine the expression of p16INK4A and survivin as possible predictive biomarkers in cervical squamous neoplasm. Material and Methods: This is a retrospective study on 201 cases of cervical neoplasm comprising of 129 cervical intraepithelial neoplasia (CIN and 72 squamous cell carcinoma (SCC. All samples were evaluated by two independent observers using p16INK4A and survivin monoclonal antibodies. The p16 INK4A expression was graded as negative, focal and diffuse positivity. The intensity for survivin expression was graded as weak, moderate and intense. Results: It is seen that p16 INK4A expression in CIN 1, CIN 2 and CIN 3 were 25.4%, 42.9% and 95.9% respectively. Majority of SCC (98.6% showed p16 INK4A expression. Survivin expressions in CIN 1, CIN 2, CIN 3 and SCC were 56.7%, 33.4%, 87.5% and 98.6%. There was a linear relationship between increasing grade of CIN and p16 INK4A expressions. Conclusion: Our study showed that p16 INK4A expressions correlate well with the increasing grade of CIN. Although survivin does not correlate well to the increasing grade of CIN, it could be useful in differentiating CIN 3 from SCC.

    In French Guiana, the age-standardized incidence rate of cervical cancer is four times higher than in France and the mortality rate 5.5 times higher. A survival study revealed that stage at diagnosis was the main factor influencing the prognosis, showing that early detection is crucial to increase cervical cancer survival. The present study aimed at evaluating the cervical cancer screening rate between 2006 and 2011 by age and for a 3-year period in French Guiana. All pap smears realised in French Guiana were analysed in two laboratories allowing exhaustive review of screening data. The screening rate was estimated at about 54% from 2006 to 2011, with a statistical difference between coastal and rural area (56.3% versus 18.7%). Although the methodological difference did not allow comparisons with metropolitan France, these results could be used to evaluate the impact of organised cervical cancer screening by the French Guiana Association for Organized Screening of Cancers which has been implemented in French Guiana since 2012.

  4. From Human Papillomavirus (HPV) Detection to Cervical Cancer Prevention in Clinical Practice

    International Nuclear Information System (INIS)

    The newly gained knowledge of the viral etiology in cervical carcinogenesis has prompted industrial interests in developing virology-based tools for cervical cancer prevention. Due to the long incubation period from viral infection to developing an invasive cancer, a process whose outcome is influenced by numerous life-style and genetic factors, the true efficacy of the genotype-specific human papillomavirus (HPV) vaccines in cervical cancer prevention cannot be determined for another 30 years. Most HPV DNA test kits designed to replace the traditional Papanicolaou (Pap) smears for precancer detection lack the analytical sensitivity and specificity to comprehensively detect all potentially carcinogenic HPVs and to perform reliable genotyping. The authors implemented the classic nested PCR and Sanger DNA-sequencing technology for routine HPV testing. The results showed a true negative HPV PCR invariably indicates the absence of precancerous cells in the cytology samples. However, 80.5% of single positive HPV-16 tests and 97.3% of single positive HPV-18 tests were associated with a negative or a largely self-reversible Pap cytology. Routine sensitive and reliable HPV type-specific or perhaps even variant-specific methods are needed to address the issues of persistence of HPV infection if a virology-based primary cervical screen is used to replace the Pap cytology screening paradigm

    Full Text Available Enterobius vermicularis also known commonly as pinworm is the most common intestinal parasite. It is a nematode that inhabits the human terminal ileum, colon and appendix. The fertilized female migrates to the perianal area where eggs are deposited but occasionally introduces itself into adjacent orifices, most commonly the female genitourinary tract. Thus the eggs can be seen in the vaginal smear as a result of contamination. We report a case wherein the patient presented with signs and symptoms of vulvovaginitis. In her vaginal smear there were eggs of Enterobius vermicularis which showed a coiled larva within it. In the background there were plenty of acute inflammatory cells. This patient responded favorably to antihelminthics. We report this case to highlight the morphology of the parasite and also to emphasize that such findings should not be neglected. Timely reporting and appropriate treatment of such cases will prevent further complications of this parasite including endometritis, salphingitis and peritonitis.

    Full Text Available HPV is closely associated with cervical cancer that the incidence of this tumor is regarded as a surrogate marker for HPV infection in countries lacking epidemiological studies. HPV is also implicated in subsets of anogenital and oro-pharyngeal cancers. Although cervical cancer is the third most common cancer in women worldwide, its reported incidence is low in Saudi Arabia, ranking number 12 between all cancers in females and accounts only for 2.4% of all new cases, despite the lack of national screening programs. However, the limited available studies from Saudi Arabia indicate that HPV prevalence and genotypes’ distribution in invasive cervical cancer show similar pattern as in the world. Cytology screening (Pap Smear and HPV vaccinations are the two preventive measures against cervical cancer. The two available vaccines are effective against the two most common HPV genotypes (HPV-16 and 18. Since 92% of cervical tumors in the Kingdom are infected with HPV of which 78% are HPV-16 and 18 genotypes, vaccination is expected to protect against more than two-third of cervical cancers in Saudi Arabia. Nevertheless, due to its low incidence (2.1/100,000 women, a proper cost-effectiveness analysis is required to justify the implementation of a costly vaccine bearing in mind that HPV could potentially be associated with about 3% of all cancers. However, further studies are needed to ascertain the real prevalence of HPV at the population level at large, its association with various types of cancers and also the impact of local tradition and emerging behavioral trends that could affect HPV transmission and consequently the effectiveness of applying national vaccination program.

    2013-01-01

    Background The World Health Organization estimated in 2010 that 8.8 million new tuberculosis (TB) cases. About one-third of the world’s population is infected and 10% will develop active TB disease. While cultures remain the international gold standard for diagnosing TB disease, in many other low-income countries, sputum smears remain the only and most accessible tool with which to diagnose active TB disease. As a consequence, in patients with TB who have negative smears, their TB remains undetected. Aim The objective of the study reported here was to demonstrate the proportion of smear-positive/culture-positive cases compared with smear-negative/culture-positive TB cases in Mexican immigrants bound for the USA. Methods A retrospective study was undertaken of the medical records of 122 active TB cases diagnosed at a clinic in Ciudad Juarez, Mexico, from 2009 to 2012. All cases were confirmed by culture, regardless of the sputum smear results. Results Of the cases, 80% (97 active TB cases) had negative sputum smears, while only 25 cases (20%) had at least one positive smear. All of the cultures were confirmed as positive for Mycobacterium tuberculosis complex. Conclusion The fact that 80% of the TB cases were smear negative and 20% smear positive shows that there is a clear gap between the actual state of active TB disease within patients under screening conditions, meaning that eight out of ten actual cases are being missed when sputum smear is the only diagnostic tool in asymptomatic patients with abnormal chest X-rays. Based on these results, it is highly recommended that countries that have not standardized culturing as the gold standard for the diagnosis of active TB do so, so that TB cases – which may endanger global public health – are not missed. It is also recommended that further studies be undertaken to determine the clinical background of the patients diagnosed by smear and culture to identify a direct relationship between clinical signs and

    International Nuclear Information System (INIS)

    Prevalence information is lacking on human papillomavirus type 16 and 18 (HPV-16/18) infections in cervical tissues of women in Riyadh, Saudi Arabia. In addition, there are no observations on progression to cervical intraepithelial neoplasia (CIN). Pap smear and HPV-16/18 detection by PCR followed by Southern blotting was performed on 120 subjects (Saudi and other Arab nationals) during routine gynecological examination. Some HPV-positive was followed for 4 years by Pap smears at every 6 months and by HPV DNA detection at the end of four years. Overall HPV-16/18 prevalence was 31.6%. HPV-16 prevalence alone was 13.3%, HPV-16 as a mixed infection with HPV-18 was 15% and all HPV-18 was 18.3%. Ten subjects had cervical abnormalities with the Pap smear test, six of whom were HPV-16/18 positive, 1 with HPV-16, 1 with HPV-18 and 4 with a mixed infection of HPV-16/18. Of all 23 HPV-16/18-positive subjects, either as individual or mixed infection, followed for years, 7 showed abnormal cytology, 6 at initial examination and 1 during follow-up. Of these 7, 6 reverted to normal without treatment and 1 was treated and became normal after 3 years. None of the subjects progressed to CIN-III. A high prevalence of HPV-16/18 was found, but with low rate of progression to CIN. A significant association with abnormal cytology was found only in patents with HPV-16/18 mixed infection. (author)

    618 women aged 13-36 attending a family planning clinic took part in a sexual health survey during 1985 and 1986. They were followed up for one year in order to ascertain whether an increase in atypical and dysplastic pap smears was linked to a certain lifestyle. The routine examination included a pap smear, a cervical swab for gonorrhea and other vaginal flora. Cultures for herpes and chlamydia were done. Benign atypia infection was treated followed by repeat pap smears 6-8 weeks and 2-3 months later. 7% of the women were virgins, 72% had smoked, and 62% presently smoked (an average of 9 cigarettes daily). Average age at first intercourse, was 16, and partners ranged from 1 to 35. Condom use was most prevalent: 15% used it "always", 20% "often", and 36% "occasionally". The oral contraceptive use pattern was: 60% "always" used it and 10% "often" relied on it. 1/4th used the rhythm method. 90% had never been pregnant, 9% had, and 1% were unsure. of 49 pregnancies 41 ended in abortion. After examining 581, 4 cases condylomata and 1 case of genital herpes were found. 60% of the women had normal cervical cytology, 32% showed atypia, and 8% displayed dysplasia. 22% of the atypias were linked to inflammation and 6% were related to yeast. 9% of repeat atypia or dysplasia was less severe by biopsy, while 54% turned out to be more severe than the pap smear results, although they tend to indicate more severe changes. 8% showed less severe cytology, and 59% more severe cytological changes. 78% of the group with mild dysplasia had smoked, as opposed to 22% that had "never smokes". Those with mild dysplasia were 4 times more likely to smoke at the time of their initial visit (79%) than nonsmokers (21%). 54% of those with normal pap smear reported "often" or "always" using condoms, whereas only 10% of the group with dysplasia reported similar use pattern. These findings uphold the practice of following the repeated atypical, or initial dysplastic pap smear results with

    The Savannah River Site (SRS) is evaluating the variables of the remote smearing process for monitoring transferable contamination on the waste glass canisters at the Defense Waste Processing Facility (DWPF). Smearing for transferable contamination is typically done by hand, but in this case, due to the nature of the high level waste within the canisters, remote smearing is required. The effectiveness of the smear pad was determined under varying conditions (distance traveled, force applied, and canister surface), as well as the relative importance of these factors. It was concluded that the remote smear is more reliable than the hand smear

    Cervical cancer is the leading cause of cancer-related mortality among women in India; however, participation in prevention and screening is low and the reasons for this are not well understood. In a cross-sectional survey in August 2008, 202 healthy women in Karnataka, India completed a questionnaire regarding knowledge, attitudes, and practices related to human papillomavirus (HPV) and cervical cancer. Factors associated with vaccination and Papanicolau (Pap) smear screening acceptance were explored. Thirty-six percent of women had heard of HPV while 15% had heard of cervical cancer. Five percent of women reported ever having a Pap smear, and 4% of women felt at risk of HPV infection. Forty-six percent of women were accepting of vaccination, but fewer (21%) were willing to have a Pap smear. Overall, knowledge related to HPV and cervical cancer topics was low. Women with negative attitudes toward HPV infection were 5.3 (95% confidence interval (CI) 2.8-10) times more likely to accept vaccination but were not significantly more likely to accept Pap smear (odds ratio 1.5, 95% CI 0.7-3.0). Cost and a low level of perceived risk were the most frequent factors cited as potential barriers. Improving awareness of HPV and cervical cancer through health care providers in addition to increasing access to vaccination and screening through government-sponsored programs may be feasible and effective methods to reduce cervical cancer burden in India.

    Full Text Available Our study evaluates the effect of an educational programme on awareness and uptake of the cervical cancer screening test (Pap smear by women in a model market in Lagos Nigeria. This was a quasi-experimental study using a multistage sampling technique. A total of 350 women were divided into two groups. A baseline survey on awareness of the Pap test and screening practices was carried out using pre-tested, interviewer administered, structured questionnaires. Participants in the intervention group received sessions of community based health information on cervical cancer screening tests while participants in the control group received health information on hypertension. Subsequently, participants in both groups were reassessed to evaluate the effect of the educational programme on the Pap test and cervical screening uptake. Data were analysed with the Epi-info version 6.04. Awareness about the Pap test was low at baseline; only 6.9% and 12.0% of participants in the intervention and control groups, respectively, had heard of Pap smears. Furthermore, less than 10% had correct information on the use of the Pap test. Post-intervention, there was a significant and proportional increase in the knowledge of the Pap test in the intervention group (p<0.05. However, uptake of the test was quite low in the intervention and control groups both pre- and post-intervention and there was no significant change in uptake. We concluded that essential schemes are required to enhance access to screening, as knowledge alone is insufficient to promote acceptance and use of cervical cytological screening tests.

    Full Text Available In Indonesia, most cervical cancer patients seek medical help after the cancer has reached advanced stage (62 %. This has caused cervical cancer to contribute to 66 % of gynecological deaths.1 The objective of this study is to find out factors related to the delay of cervical cancer patients in seeking for medical help. This research employs quantitative and qualitative methods. Samples were obtained from all of the new cervical cancer patients who came for the first time between 2000 to 2001 and returned to the Dr. Cipto Mangunkusumo National Central General Hospital Jakarta from August until October 2001. It is concluded that variables significantly correlated with the delay for medical check up are knowledge, attitude, the availability of Pap smear service and husband support. The availability of Pap smear plays as dominant variabel.

  7. Loss of accuracy using smeared properties in composite beam modeling

    Science.gov (United States)

    Liu, Ning

    Advanced composite materials have broad, proven applications in many engineering systems ranging from sports equipment sectors to components on the space shuttle because of their lightweight characteristics and significantly high stiffness. Together with this merit of composite materials is the challenge of improving computational simulation process for composites analysis. Composite structures, particularly composite laminates, usually consist of many layers with different lay-up angles. The anisotropic and heterogeneous features render 3D finite element analysis (FEA) computationally expensive in terms of the computational time and the computing power. At the constituent level, composite materials are heterogeneous. But quite often one homogenizes each layer of composites, i.e. lamina, and uses the homogenized material properties as averaged (smeared) values of those constituent materials for analysis. This is an approach extensively used in design and analysis of composite laminates. Furthermore, many industries tempted to use smeared properties at the laminate level to further reduce the model of composite structures. At this scale, smeared properties are averaged material properties that are weighted by the layer thickness. Although this approach has the advantage of saving computational time and cost of modeling significantly, the prediction of the structural responses may not be accurate, particularly the pointwise stress distribution. Therefore, it is important to quantify the loss of accuracy when one uses smeared properties. In this paper, several different benchmark problems are carefully investigated in order to exemplify the effect of the smeared properties on the global behavior and pointwise stress distribution of the composite beam. In the classical beam theory, both Newtonian method and variational method include several ad hoc assumptions to construct the model, however, these assumptions are avoided if one uses variational asymptotic method.

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.

    Cervical spinal cord injury is a rare but serious complication after general anesthesia. The risk factors include traumatic cervical injury, cervical spine instability, and difficult airway management. It has also occurred in the absence of cervical instability. Here we report a patient who had a history of intermittent neck pain without numbness. Preoperative radiologic examinations showed degenerative changes in the cervical spine. She developed progressive tingling and numbness in her limbs after thyroidectomy under general anesthesia. Magnetic resonance imaging showed a cervical disc protruding into the canal at C5-C6, which was considered to be induced by surgical positioning. She recovered after anterior cervical decompression and internal fixation surgery. PMID:23828450

    Despite cervical cancer being potentially preventable, it is the second most common cancer among women in Malaysia. One hundred and five articles related to Cervical Cancer were found in a search through a database dedicated to indexing all original data relevant to medicine published in Malaysia between the years 2000-2013. Fifty seven articles were selected and reviewed for the articles' clinical relevance and future research implications. This article reviews the various aspects of cervical cancer in Malaysia, mainly persistent infection of high risk human papillomavirus (HPV), primary prevention (HPV vaccination), screening method (Pap smear issues), and the attitude and knowledge of various groups of Malaysian women that contributed to the failure to reduce the incidence and mortality of cervical cancer. Most of the studies focused on prevention, Pap smear issues, HPV DNA testing, HPV vaccination and various recommendations for prevention of cervical cancer. Secondary prevention by screening is still an important aspect because even with HPV vaccination, screening still plays an important role as vaccination does not cover all high risk HPVs. There is a need to seriously consider a properly organised screening programme, taking into consideration what we already know about the attitude and knowledge of Malaysian women, economic factors and psychosocial issues of the screening method. There is also a large gap in clinical studies on the outcome, management and survival of cervical cancer patients in Malaysia. PMID:25417949

  16. Dynamics at a smeared phase transition

    International Nuclear Information System (INIS)

    We investigate the effects of rare regions on the dynamics of Ising magnets with planar defects, i.e., disorder perfectly correlated in two dimensions. In these systems, the magnetic phase transition is smeared because static long-range order can develop on isolated rare regions. We first study an infinite-range model by numerically solving local dynamic mean-field equations. Then we use extremal statistics and scaling arguments to discuss the dynamics beyond mean-field theory. In the tail region of the smeared transition the dynamics is even slower than in a conventional Griffiths phase: the spin autocorrelation function decays like a stretched exponential at intermediate times before approaching the exponentially small equilibrium value following a power law at late times

    This study assesses knowledge and attitudes of medical students of the faculty of medicine of Tunis, at the end of their medical curriculum, towards breast and cervical cancer screening. Among the 644 medical students at the end of their curriculum, 592 answered to anonymous questionnaire (response rate = 92%). Results show that 34.1% have proposed systematic cervical cancer screening. This proportion was 61.0% for clinical breast cancer examination. The majority of students (70.2%) proposed to start this cervical screening since the first sexual activities. As for the periodicity of this screening, 44.2% are favourable for a yearly periodicity, 39.2% for every three years, 7.2% for every five years and 9.4% for a periodicity at least once in life. 94.1% of students declared to have learned clinical breast examination, contrarily to pap smear, for which this proportion was only 55.1%. Breast and cervical cancer control training, in the faculty of medicine of Tunis, is insufficient and should be improved and restructured. PMID:17561734

    Cervical cancer disproportionately affects minorities, immigrants and low-income women in the USA, with disparities greatest among Latino immigrants. We examined barriers and facilitators to cervical cancer screening practices among a group of immigrant Latino women in Florida, USA. Between January and May 2013, six focus group discussions, involving 35 participants, were conducted among Hispanic women in Miami to explore their knowledge, beliefs about cervical cancer and facilitators and barriers to cervical cancer screening using a theoretical framework. The data showed that family support, especially from female relatives, was an important facilitator of screening and treatment. Women, however, reported prioritising family health over their own, and some expressed fatalistic beliefs about cancer. Major obstacles to receiving a Pap smear included fear that it might result in removal of the uterus, discomfort about being seen by a male doctor and concern that testing might stigmatise them as being sexually promiscuous or having a sexually transmitted disease. Targeted education on cancer and prevention is critically needed in this population. Efforts should focus on women of all ages since younger women often turn to older female relatives for advice.

    Full Text Available Background: Cervical cancer is the second most common cancer among Iranian women and among the few cancers that could be easily diagnosed in the pre-malignant stage. We aimed to assess the status of cervical cancer screening in women referred to health care centres in Tabriz, northwest Iran. Materials and Methods: This descriptive-analytical study was done on 441 women referred to health care centres of Tabriz, northwest Iran. The centres were selected using the multi-stage cluster sampling method. The participants were selected from the active records of those centres. A questionnaire regarding the socio-demographic characteristics and cervical cancer screening and reasons for referring or not referring for screening was completed by the participants A P < 0.05 was considered as significant. Results: Out of the participants 49.4% of women had done the Pap smear test while 50.6% had never done this test. The main reason why women had not performed cervical cancer screening was being unaware of the importance of it (46.1%. Logistic regression analysis with adjustment showed a significant relationship between screening and awareness scores (OR = 1.17, CI = 95%:1.12-1.23, when the effect of other confounding factors [total awareness scores, risk factors (marriage or having sexual intercourse at a young age, history of obvious cervical infection, cautery, cryotherapy or repeated curettage, age and type of family planning] in screening was controlled. Conclusion: Suitable and continuous educational programmes especially for high risk women should be implemented through the health care services. Preparing educational brochures and pamphlets and providing adequate training on the necessity of early referral and marriage counseling could also be effective in improving woman′s awareness and performance.

The study sample consisted of 114 women from 18 to 50 years old who attended the Family Health Strategy to have a smear test in October and November 2010. The descriptive analysis performed using Epi Info 3.5.1 showed that the higher level of adherence is in the 46 to 50 years age group (24% and the lower level is at 18 to 20 and 41 to 45 years (10% each. Among the interviewees, 70% had the test every two years or less and 12% had never had it. The Family Health Strategy unit with higher adherence was Jadim Monte Alto with 16%, and the lower was Umuarama district with 8%. It was concluded that prevention is the main reason for women to take the smear test.

  3. The Shape of Covariantly Smeared Sources in Lattice QCD

    2013-01-01

    Covariantly smeared sources are commonly used in lattice QCD to enhance the projection onto the ground state. Here we investigate the dependence of their shape on the gauge field background and find that the presence of localized concentrations of magnetic field can lead to strong distortions which reduce the smearing radii achievable by iterative smearing prescriptions. In particular, as $a\\to 0$, iterative procedures like Jacobi smearing require increasingly large iteration counts in order to reach physically-sized smearing radii $r_{sm}\\sim$ 0.5 fm, and the resulting sources are strongly distorted. To bypass this issue, we propose a covariant smearing procedure (``free-form smearing'') that allows us to create arbitrarily shaped sources, including in particular Gaussians of arbitrary radius.

    Fluorescence in situ hybridization (FISH) technology has been widely recognized as a promising molecular and biomedical optical imaging tool to screen and diagnose cervical cancer. However, manual FISH analysis is time-consuming and may introduce large inter-reader variability. In this study, a computerized scheme is developed and tested. It automatically detects and analyzes FISH spots depicted on microscopic fluorescence images. The scheme includes two stages: (1) a feature-based classification rule to detect useful interphase cells, and (2) a knowledge-based expert classifier to identify splitting FISH spots and improve the accuracy of counting independent FISH spots. The scheme then classifies detected analyzable cells as normal or abnormal. In this study, 150 FISH images were acquired from Pap-smear specimens and examined by both an experienced cytogeneticist and the scheme. The results showed that (1) the agreement between the cytogeneticist and the scheme was 96.9% in classifying between analyzable and unanalyzable cells (Kappa=0.917), and (2) agreements in detecting normal and abnormal cells based on FISH spots were 90.5% and 95.8% with Kappa=0.867. This study demonstrated the feasibility of automated FISH analysis, which may potentially improve detection efficiency and produce more accurate and consistent results than manual FISH analysis.

    We proposed a method for automatic detection of cervical cancer cells in images captured from thin liquid based cytology slides. We selected 20,000 cells in images derived from 120 different thin liquid based cytology slides, which include 5000 epithelial cells (normal 2500, abnormal 2500), lymphoid cells, neutrophils, and junk cells. We first proposed 28 features, including 20 morphologic features and 8 texture features, based on the characteristics of each cell type. We then used a two-level cascade integration system of two classifiers to classify the cervical cells into normal and abnormal epithelial cells. The results showed that the recognition rates for abnormal cervical epithelial cells were 92.7% and 93.2%, respectively, when C4.5 classifier or LR (LR: logical regression) classifier was used individually; while the recognition rate was significantly higher (95.642%) when our two-level cascade integrated classifier system was used. The false negative rate and false positive rate (both 1.44%) of the proposed automatic two-level cascade classification system are also much lower than those of traditional Pap smear review.

    In the context of the early recognition of cervical cancer the cytology has to detect tumor positive cases among a bulk of un suspicious specimens. Unfortunately there is a group of cases with a vague diaxosis, the so called PAP-ill-group. There are many reasons for the recent impossibility of a safe conclusion from the PAP-Ill-smears to their histological diagnoses (Pig. 1). Today for an exact statement a cone biopsy and a microscopical investigation of its histological sections for such caseS are necessary. That results in a high medical and economical expense and, last not least, that means a higher risk of complications and of future family planning problems for the women affected.

    Cervical cancer is the third most common form of cancer that strikes Malaysian women. The National Cancer Registry in 2006 and 2007 reported that the age standardized incidence (ASR) of cervical cancer was 12.2 and 7.8 per 100,000 women, respectively. The cumulative risk of developing cervical cancer for a Malaysian woman is 0.9 for 74 years. Among all ethnic groups, the Chinese experienced the highest incidence rate in 2006, followed by Indians and Malays. The percentage cervical cancer detected at stage I and II was 55% (stage I: 21.0%, stage II: 34.0%, stage III: 26.0% and stage IV: 19.0%). Data from Ministry of Health Malaysia (2006) showed a 58.9% estimated coverage of pap smear screening conducted among those aged 30-49 years. Only a small percentage of women aged 50-59 and 50-65 years old were screened, 14% and 13.8% coverage, respectively. Incidence of cervical cancer was highest (71.6%) among those in the 60-65 age group (MOH, 2003). Currently, there is no organized population-based screening program available for the whole of Malaysia. A pilot project was initiated in 2006, to move from opportunistic cervical screening of women who attend antenatal and postnatal visits to a population based approach to be able to monitor the women through the screening pathway and encourage women at highest risk to be screened. The project was modelled on the screening program in Australia with some modifications to suit the Malaysian setting. Substantial challenges have been identified, particularly in relation to information systems for call and recall of women, as well as laboratory reporting and quality assurance. A cost-effective locally-specific approach to organized screening, that will provide the infrastructure for increasing participation in the cervical cancer screening program, is urgently required.

    In the evaluation of biological potentials of contraceptives in the genesis of cervical cancer, cytology seems to have been given due attention while information on the clinical condition and specific treatment of the target organ, the cervix, is repeatedly neglected. "Cancer does not develop in a healthy cervix" is an old dogma derived from impressions gained by clinical examination of the organ. This concept is supported by epidemiologic studies indicating that cancer is extremely rare in cervices restored to a normal condition by cauterization. It may be postulated that this type of treatment destroys the permissive target cells of the cervix, thus indirectly rendering possible coitus-associated and contraceptive-associated(?) mutagen(s) invalid. Also, in comparative studies, an evaluation should be made of the significance of a higher incidence of cervical ectopy reported in women receiving oral hormonal contraceptives. The importance of ectopy in the genesis of cervical malignancy has been derived from the presumption that permissive cervical cells are thus created and exposed to vaginal contents which may harbor the mutagens(s). Therefore, it would seem not only desirable but imperative to include the neglected parameters of clinical condition and of specific treatment (both past and present) of the uterine cervix in the structure of studies like the recent one in this Journal on "Contraceptive choice and cervical cytology", by Drs. Shulman and Merritt. Still another parameter which might prove to be of significance is the predominant type of vaginal flora, which can be assessed readily in the routine examination of Papanicolaou smears. It may be that vaginal contents, which would seem to be somewhat different in wearers of the intrauterine contraceptive device as compared to "pill" users, might play a part in the advent of cervical malignancy as a medium of or for coitus-associated mutagens(s).

    Full Text Available Cervical spondylosis is a common, chronic degenerative condition of the cervical spine that affects the vertebral bodies and intervertebral disks of the neck as well as the contents of the spinal canal. Common clinical syndromes associated with cervical spondylosis include cervical pain, cervical radiculopathy and/or mielopathy. This study show the main principles, indication and side effects of tuina in cervical spondylosis´ treatment; tuina is one of the external methods based on the principles of Traditional Chinese Medicine (TCM, especially suitable for use on the elderly population and on infants. While performing Tuina, the therapist concentrates his mind, regulates his breathing, and actuates the Qi and power of his entire body towards his hands. For a better result is recommended to try to combine acupuncture with tuina treatment. Tuina can help relieve the pain associated with spondylosis. After this kind of treatment, the symptomes produced by irritated nerves and sore muscles can find some relief. Tuina helps patients with cervical spondylosis regain muscle control, nerve function and flexibility, all through the restoration of the life force flow.

    Objective: The role of human papillomavirus (HPV) in the development of cervical carcinoma has been clearly established but other factors could be involved in cervical tumorigenesis such as loss of heterozygosity (LOH) and microsatellite instability (MI). The aim of the present study was to investigate the genetic instability in cervical carcinoma tissues and provide evidence for discoveringnew tumor suppressor genes and screening diagnostic molecular marker of cervical carcinoma. Methods: Fifty primary cervical carcinoma samples from high-incidence area were analyzed by PCR for HPV16 infection, LOH and microsatellite instability. Results: HPV16 was detected in 88% of the cases. Sixty-six percent of total cases showed LOH with no more than 3 different loci per case. The highest frequency of the allelic loss was found in D18S474 (18q21, 40.5%). MI was detected in 4 cases (8%) only. Conclusion: Different percentages of LOH on specific chromosomal regions were found and MI was very infrequent in cervical carcinoma. The putative suppressor gene(s) could be located on specific chromosome regions such as 18q, and genetic instability could be involved in cervical tumorigenesis.

    Full Text Available Tuberculosis of cervix is a rare disease. Tuberculosis usually affects women of childbearing age, indicating hormone dependence of infection. The patient presents with menstrual irregularities, infertility or vaginal discharge. Cervical lesions presents as papillary/vegetative growth or ulceration mimicking cervical cancer. Cervical Papanicolaou (Pap smear plays an important role in diagnosing the disease by non-invasive technique in which the presence of epithelioid cells and Langhan′s type of giant cells is diagnostic. However, other causes of granulomatous cervicitis should be considered and ruled out. Ziehl-Neelsen (ZN stain for acid fast bacilli, fluorescent technique, biopsy and culture help in confirming the disease. We present the case of a 45-year-old female, who presented with vaginal discharge, dysfunctional uterine bleeding, first degree uterine descent with grade II cystocele and rectocele and cervical ulcer. Pap smear revealed epithelioid cells and Langhan′s type of giant cells, confirmed by ZN stain of cervical smear, fluorescent technique and culture.

    Full Text Available Background: Breast carcinoma is the most common malignant tumor and leading cause of cancer deaths in women. While fine needle aspiration cytology is highly accurate in the diagnosis of breast lesions, it possesses certain drawbacks. In those circumstancesintraoperative imprint cytology assumes importance, however, imprint cytology is subjected to interpretative errors. Computer image analysis has become an important tool in the pathology laboratory for quantitative morphometric analysis. The purpose of this study was to compare the morphometric values of various breast lesions onintraoperative imprint smears with final histopathological sections.Methods: The study group comprised 30 cases of, borderline(suspicious, and malignant lesions. Intraoperative imprint smears were stained with hematoxylin and eosin, and toluidine blue. Morphometry was done on these smears and compared with morphometry on the histopathological sections, followed by statistical correlation. We studied the following five parameters: mean nuclear area, mean nuclear diameter, mean nuclear perimeter, feret circle, and nucleo-cytoplasmic ratio.Results: In the current work, all of the studied parameters with the exception of feret circle showed significantly lower values in benign ductal epithelial cells compared to malignant lesions and concentrate on the importance of morphometry as a diagnostictool that could differentiate benign from malignant lesions, especially if it can be employed on imprint smears intraoperatively. Accurate assessment of intraoperative margins by imprint smears using image analysis automation can prevent multiple reexcisionprocedures in breast conservation surgery.

  17. Instabilities of near-extremal smeared branes and the correlated stability conjecture

    International Nuclear Information System (INIS)

    We consider the classical and local thermodynamic stability of non- and near-extremal Dp-branes smeared on a transverse direction. These two types of stability are connected through the correlated stability conjecture for which we give a proof in this specific class of branes. The proof is analogous to that of Reall for unsmeared branes, and includes the construction of an appropriate two-parameter off-shell family of smeared Dp-brane backgrounds. We use the boost/U-duality map from neutral black strings to smeared black branes to explicitly demonstrate that non-and near-extremal smeared branes are classically unstable, confirming the validity of the conjecture. For near-extremal smeared branes in particular, we show that a natural definition of the grand canonical ensemble exists in which these branes are thermodynamically unstable, in accord with the conjecture. Moreover, we examine the connection between the unstable Gregory-Laflamme mode of charged branes and the marginal modes of extremal branes. Some features of T-duality and implications for the finite temperature dual gauge theories are also discussed

    Full Text Available Abstract 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.

  19. Antenna induced range smearing in MST radars

    1984-01-01

    There is considerable interest in developing stratosphere troposphere (ST) and mesosphere stratosphere troposphere (MST) radars for higher resolution to study small-scale turbulent structures and waves. At present most ST and MST radars have resolutions of 150 meters or larger, and are not able to distinguish the thin (40 - 100 m) turbulent layers that are known to occur in the troposphere and stratosphere, and possibly in the mesosphere. However the antenna beam width and sidelobe level become important considerations for radars with superior height resolution. The objective of this paper is to point out that for radars with range resolutions of about 150 meters or less, there may be significant range smearing of the signals from mesospheric altitudes due to the finite beam width of the radar antenna. At both stratospheric and mesospheric heights the antenna sidelobe level for lear equally spaced phased arrays may also produce range aliased signals. To illustrate this effect the range smearing functions for two vertically directed antennas have been calculated, (1) an array of 32 coaxial-collinear strings each with 48 elements that simulates the vertical beam of the Poker Flat, Glaska, MST radar; and (2) a similar, but smaller, array of 16 coaxial-collinear strings each with 24 elements.

  20. Tuberculosis treatment among smear positive tuberculosis patients

    International Nuclear Information System (INIS)

    Tuberculosis is a major health problem in many parts of the world. Delay in initiation of the treatment may result in prolonged infectious state, drug resistance, relapse and death. Objectives: To determine the factors responsible for not starting tuberculosis treatment among smear positive tuberculosis patients. Study type, settings and duration: This cross sectional study was done at Pakistan Medical Research Council TB Research Center, King Edward Medical University, Lahore, from fifth March 2010 to fifth December 2010. Patients and Methods: Fifty sputum smear positive patients of tuberculosis who did not register themselves in treatment register and presumably did not initiate anti tuberculosis treatment were contacted using telephone or traced by their home addresses. Once contact was established, they were inquired about the reasons for not starting tuberculosis treatment. Results: Of 50 patients 38(76%)belonged to the lower socio economic class and 12(24%) to the lower middle class. Fourteen patients (28%) were illiterate and 23(46%) had only 8 years of education. Of the 50 cases 41(82%) were taking treatment from traditional healers and 4% did not go back to the DOTS program. Physical condition of the patient, social, domestic and religious issues also played some role in default. Conclusions: Lack of health education and poverty were the main factors responsible for non compliance from treatment. Policy message: Sputum testing sites should have a paramedic who should educate the patients about the benefits of treatment and the dangers of default or partial treatment. (author)

    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. PMID:26810061

    Buffy coat smears from febrile patients may contain visible bacteria and therefore detect bacteraemia before conventional blood cultures become positive. However, it is unusual to see micro-organisms in an otherwise untreated peripheral blood smear. The case of a febrile neutropenic patient is reported. A Wright's stained peripheral blood smear contained bacterial elements, thus making earlier diagnosis of septicaemia and identification of the causative bacterium possible.

    Cell enumeration and diagnosis using peripheral blood smears are routine tasks in many biological and pathological examinations. Not every area in the smear is appropriate for such tasks due to severe cell clumping or sparsity. Manual working area selection is slow, subjective, inconsistent and statistically biased. Automatic working area classification can reproducibly identify appropriate working smear areas. However, very little research has been reported in the literature. With the aim of...

    Full Text Available Introduction: modern knowledge could protect against cancer for individuals in community with early stage and premalignat state. Screening of cancer is best instrument for early detection of malignancy. Between women’s cancers breast and cervical cancer have more incidence and mortality than other cancers . But could be prevented by simple and cheep screening programs. Despite specific statistics in Iran evidence shows that women’s participation in screening program is poor , so cancers are diagnosed in advanced stage. The purpose of this study was to identify major barriers and motivators for breast and cervical screening . Methods: This survey was a descriptive study in which 400 women participated in health and treatment centers in Yazd. Sampling method was done in two simple and random stages. Data was collected by inventory and questionnaire . Then data were analyzed by SPSS soft ware . Results: Findings showed that 80% of them never refereed to a health provider for clinical breast exam (C B E and only 3% of them did regularly C B E . 46% of them had never done pap smear and only 14.5 % of them did regularly pap smear. The findings showed that major motivators were as follow: advice of health’s personnel , using of contraceptive methods , and awareness of media. Also the major barriers were as follow : Not having knowledge of these exams , not having knowledge of the existence of these centers of education and practice , not having precious health problems , fear of examination , Embarrassment of examination and health providers not to teach them . to consider the most important barriers were propounded which showed that health education role to eliminate barriers for referring women for screening . Discussion: Based on the results of this sample , screening was the least expected . considering barriers and motivators observed it was revealed that health education was required for prevention of common women’s cancers.

    We show that phase transitions in Ising systems with planar defects, i.e., disorder perfectly correlated in two dimensions are destroyed by smearing. This is caused by effects similar to but stronger than the Griffiths phenomena: exponentially rare spatial regions can develop true static long-range order even when the bulk system is still in its disordered phase. Close to the smeared transition, the order parameter is very inhomogeneous in space, with the thermodynamic (average) order parameter depending exponentially on temperature. We determine the behaviour using extremal statistics, and we illustrate the results by computer simulations.

    Increased expression of viral E6 and E7 oncoproteins within the host cells results in an increase in cellular protein p16INK4a expression. That increase may serve as a marker for dysplastic and neoplastic cells of the uterine cervical epithelium. The aim of this study is to assess the p16INK4a protein expression in different stages of cytological abnormality in correlation with the proven high oncogenic risk human papillomavirus infection in order to demonstrate its value as the diagnostic marker. The study included cervical smear samples of 371 patient in whom the viral typization was done. In 171 patient, during their regular gynaecological examination, along with conventional Pap smear sampling an additional smear was taken. Two hundred cervix brush (Rovers Medical DevicesOss, the Netherlands) samples were obtained and analyzed by the LBC method and the ThinPrep2000 machine. All samples were analyzed cytologically, classified according to the Bethesda system, and immunostained with the p16INK4a-specific monoclonal antibody E6H4 (MTM Laboratories, Heidelberg, Germany). A significant difference is seen in p16 positivity between the cytological diagnosis of a high grade cervical squamous intraepithelial lesion and the group with mild dysplasia (chi2=146,48; D.F.=4; ptechnique renders it suitable for follow-up monitoring as well as for comparison of the cytological results.

    The peripheral blood smear is an easy method for the diagnosis of symptomatic visceral leishmaniasis (VL) in human immunodeficiency virus type 1 (HIV-1)-infected patients. However, its efficiency in diagnosing subclinical VL remains unknown. In this study, Leishmania amastigotes were seen in blood smears from 1 of 13 HIV-1-positive individuals with subclinical VL. This shows that this procedure is not suitable for subclinical-VL diagnosis.

    HPLC combined with laser induced fluorescence provides a very sensitive method for the separation and identification of the many proteins present in clinical samples. Protein profiles of clinical samples like Pap smear and tissue samples, from subjects with cervical cancer and normal volunteers, were recorded using HPLC-LIF. The protein profiles were analyzed by Principal Component Analysis (PCA). The profiles were characterized by parameters like scores of the factors, sum of squared residuals, and Mahalanobis Distance, derived from PCA. Parameters of each sample were compared with those of a standard set and Match/ No Match results were generated. Good discrimination between normal and malignant samples was achieved with high sensitivity and specificity.

    The incidence of Chlamydia trachomatis (CT) & Neisseria gonorrhoeae (NG) are rising in Ireland. Both are often undiagnosed and may cause infertility amongst other complications. CT/NG screening is not routinely offered during cervical cancer screening. This study aimed to ascertain the feasibility and acceptability of screening for CT/NG at time of smear and to measure the diagnostic yield. Screening was offered to women aged 25-40 years attending four participating general practices as part of Cervical Check. A retrospective review of the three months preceding the study period, indicated that out of 138 smears, CT/NG testing was performed in 10 (7%) of cases. 236 (93%) patients consented to screening for CT/NG. The detection rate for Chlamydia was 6 (2.4%), with no positive results for NG. Feedback from patients was positive. Interestingly, 42 (18%) of participants who completed the questionnaire believed STI screening was already part of the routine smear. PMID:26904785

    Full Text Available Accurate classification of Pap smear images becomes the challenging task in medical image processing. This can be improved in two ways. One way is by selecting suitable well defined specific features and the other is by selecting the best classifier. This paper presents a nominated texture based cervical cancer (NTCC classification system which classifies the Pap smear images into any one of the seven classes. This can be achieved by extracting well defined texture features and selecting best classifier. Seven sets of texture features (24 features are extracted which include relative size of nucleus and cytoplasm, dynamic range and first four moments of intensities of nucleus and cytoplasm, relative displacement of nucleus within the cytoplasm, gray level cooccurrence matrix, local binary pattern histogram, tamura features, and edge orientation histogram. Few types of support vector machine (SVM and neural network (NN classifiers are used for the classification. The performance of the NTCC algorithm is tested and compared to other algorithms on public image database of Herlev University Hospital, Denmark, with 917 Pap smear images. The output of SVM is found to be best for the most of the classes and better results for the remaining classes.

    Hepatic coccidiosis is a contagious and lethal disease condition in rabbits. The disease was recorded in six rabbits suffering with watery diarrhoea. Clinically, affected rabbits showed decreased growth rate, anorexia, debilitation, diarrhea and rough hair coat. Examination of the faecal samples revealed the presence of unsporulated oocysts of Eimeria spp. After sporulation Eimeria stiedae oocysts were identified. Postmortem examination revealed hepatomegaly with presence of discrete yellowish-white nodules on the surface of the liver. Impression smears from the liver revealed the presence of numerous developmental stages of E. stiedae corresponding with the stage of the liver lesion and also represent the histological changes of the liver. Rabbits were treated with a combination of sulphaquinoxaline and diaveridine for five days. PMID:27605807

    Full Text Available Abstract Background Data from Egyptian studies provide widely varying estimates on the prevalence of pre-malignant and malignant cervical abnormalities and human papilloma virus (HPVs infection. To define the prevalence and risk factors of pre-invasive and invasive cervical cancer (cacx, a community based full-scale cross sectional, household survey including 5453 women aged between 35 and 60 years was conducted. Methods The study period was between February 2000 and December 2002. Initially, conventional Papanicolaou (Pap smears were evaluated using the Bethesda system (TBS, followed by colposcopic guided biopsy (CGB for all epithelial abnormalities (EA. In a third step, HPV was tested on all EA by in-situ hybridization (ISH using first the broad spectrum HPV probe recognizing HPVs 6, 11, 16, 18, 30, 31, 35, 45, 51 and 52 followed by subtyping with probes 6/11, 16/18 and 31/33. Lastly, unequivocal cases were immunostained for herpes simplex type-2 (HSV-2, cytomegalovirus (CMV, and human immunodeficiency virus (HIV. Results EA representing 7.8% (424/5453, were categorized into atypical squamous cell of undetermined significance (ASCUS (34.4%, atypical glandular cell of undetermined significance (AGCUS (15.3%, combined ASCUS and AGCUS (3.1%, low grade squamous intraepithelial lesions (SIL (41.0%, high grade SIL (5.2% and invasive lesions (1%.

    Finding malignant cells in Pap smear images is a "needle in a haystack"-type problem, tedious, labor-intensive and error-prone. It is therefore desirable to have an automatic screening tool in order that human experts can concentrate on the evaluation of the more difficult cases. Most research on automatic cervical screening tries to extract morphometric and texture features at the cell level, in accordance with the NIH "The Bethesda System" rules. Due to variances in image quality and features, such as brightness, magnification and focus, morphometric and texture analysis is insufficient to provide robust cervical cancer detection. Using a microscopic spectral imaging system, we have produced a set of multispectral Pap smear images with wavelengths from 400 nm to 690 nm, containing both spectral signatures and spatial attributes. We describe a novel scheme that combines spatial information (including texture and morphometric features) with spectral information to significantly improve abnormal cell detection. Three kinds of wavelet features, orthogonal, bi-orthogonal and non-orthogonal, are carefully chosen to optimize recognition performance. Multispectral feature sets are then extracted in the wavelet domain. Using a Back-Propagation Neural Network classifier that greatly decreases the influence of spurious events, we obtain a classification error rate of 5%. Cell morphometric features, such as area and shape, are then used to eliminate most remaining small artifacts. We report initial results from 149 cells from 40 separate image sets, in which only one abnormal cell was missed (TPR = 97.6%) and one normal cell was falsely classified as cancerous (FPR = 1%).

    Purpose: Cervical cancer is cancer that starts in the cervix, the lower part of the uterus (womb) that opens at the top of the vagina. It is the third most common type of cancer in women. Cervical cancers start in the cells on the surface of the cervix. Most cervical cancers are from squamous cells. It starts as a precancerous condition called dysplasia. This precancerous condition can be detected by a Pap smear and is 100% treatable. It can take years for precancerous changes to turn into cervical cancer. The Papanicolaou test (also called Pap smear, Pap test, cervical smear, or smear test) is a screening test used to detect potentially precancerous and cancerous processes in the endocervical canal (transformation zone) of the female reproductive system. The test aims to detect potentially precancerous changes (called cervical intraepithelial neoplasia (CIN) or cervical dysplasia), which are usually caused by sexually transmitted human papillomaviruses. The present study was planned in the direction to evaluate. Method: In the present work, overall 50 patients of age group between 2050 yrs were selected to study their abnormal pap smear reports in relation to socioeconomic status, smoking, parity, and oral contraceptive and their relationship with abnormal cellular changes. So the patients were randomly selected for Pap smear from IPD or OPD of prasuti tantra and stri roga department of sdmca Hassan. Result: Out of 50 patients,10 patients belongs to higher class, 20 patients belongs to middle class,10 patients belongs lower middle class and 10 patients belongs to lower class. Conclusion: Cervical cancer is ranked as the most frequent cancer in women in India. India has a population of approximately 365.71 million women above 15 years of age, who are at risk of developing cervical cancer. Getting regular Pap smears can help detect precancerous changes, which can be treated before they turn into cervical cancer. Pap smears effectively spot such changes, but they

    This study was conducted to 1206 women who had cervical cancer screening at Chonburi Cancer Hospital. The spilt-sample study aimed to compare the efficacy of abnormal cervical cells detection between liquid-based cytology (LBC) and conventional cytology (CC). The collection of cervical cells was performed by broom and directly smeared on a glass slide for CC then the rest of specimen was prepared for LBC. All slides were evaluated and classified by The Bethesda System. The results of the two cytological tests were compared to the gold standard. The LBC smear significantly decreased inflammatory cell and thick smear on slides. These two techniques were not difference in detection rate of abnormal cytology and had high cytological diagnostic agreement of 95.7%. The histologic diagnosis of cervical tissue was used as the gold standard in 103 cases. Sensitivity, specificity, positive predictive value, negative predictive value, false positive, false negative and accuracy of LBC at ASC-US cut off were 81.4, 75.0, 70.0, 84.9, 25.0, 18.6 and 77.7%, respectively. CC had higher false positive and false negative than LBC. LBC had shown higher sensitivity, specificity, PPV, NPV and accuracy than CC but no statistical significance. In conclusion, LBC method can improve specimen quality, more sensitive, specific and accurate at ASC-US cut off and as effective as CC in detecting cervical epithelial cell abnormalities.

    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.

    Introduction The goal of endodontic therapy is to completely eliminate the microorganisms and the smear layer from the root canal in order to provide a good seal of the root filling materials. Aim The aim of this study was to find a viable alternative irrigant, which is easily available with less erosion and clinically acceptable smear layer removal by comparing the efficacy of EDTA and commercially available super-oxidized water, named Oxum, as a final rinse on smear layer removal and erosion in relation to coronal, middle and apical thirds of radicular dentin using Scanning Electron Microscope (SEM) analysis. Materials and Methods Freshly extracted 30 human lower second premolar teeth with straight roots and type I canal anatomy were selected. The root canals were cleaned and shaped using Universal Protaper Rotary System. Irrigation was performed with 1 ml of 2.5% of NaOCl solution after each instrument change. The final irrigation (5 ml) sequence was as follows: Group I- 17% EDTA, Group II – OXUM, and Group III - 0.9% saline (control) for one minute. Then, the root canals were finally irrigated with 5ml of distilled water to remove any precipitate. The roots were then gently split into two halves using a chisel and subjected to SEM analysis. Results The SEM photomicrographs were evaluated by two independent examiners and Mann Whitney results showed that there was no statistically significant difference between the two examiners. Non-parametric statistical analysis of all experimental groups showed significant difference between coronal, middle and apical third for smear layer removal with p-value<0.05. For erosion, in group II (oxum) showed statistically significant difference between coronal, middle and apical third and it showed significantly less dentine erosion when compared to EDTA. Conclusion Within the limitations of the present study, Oxum the commercially available super-oxidized water proved to be equally effective in smear layer removal with less

    Full Text Available Abstract Background The organized Cervical Cancer Screening Programme (CCSP in Italy might represent an occasion to deliver smoking cessation (SC counselling to women attending the Pap test examination. Evidence of effectiveness of physical activity (PA promotion and intervention in adjunct to SC counselling is not strong. Objective of the SPRINT trial was to evaluate the effectiveness of a standard SC counselling intervention delivered by trained midwives in the CCSP, and whether the adjunct of a PA counselling to the SC counselling might increase quit rates. Methods/Design We undertook a randomized controlled trial of 1,100 women undergoing the Pap examination in the three study centres Florence, Turin, and Mantua: 363 were randomly assigned to the SC counselling arm, 366 to the SC + PA counselling arm, and 371 to the control group. The intervention was a standard brief SC counselling combined with a brief counselling on increasing PA, and was tailored according to the Di Clemente-Prochaska motivational stages of change for SC and/or PA. Primary outcomes were quit rates, improvement in the motivational stages of change for SC, and reduced daily cigarette consumption. Analysis was by intention to treat. Results Participants randomized in both intervention arms and in the preparation stage of change for SC doubled their likelihood of quitting at 6-month follow-up in comparison to controls (odds ratio [OR]=2.1, 95% confidence interval [95% CI]:1.0-4.6. Moreover, participants in the intervention arms and in the contemplation stage were more likely to reduce their daily cigarette consumption after the intervention (OR=1.8, 95% CI:1.1-3.0. Our study did not show any effect of PA counselling on various outcomes. Conclusions Smoking cessation counselling delivered by midwives to smokers in preparation and contemplation stages of change during the Pap-smear screening was effective and should be recommended, given the high number of women attending

    Cervical cancer is recognized as tobacco-related malignancy. HPV vaccination and introducing screening protocols were found as the best way to decrease cervical cancer related mortality. Besides the cytological screening programs of the uterine cervix smear, nowadays co-factors of carcinogenesis are taken into consideration, also. The aim of our study was to analyse data included in questionnaire of 310 women who underwent cytological examination wi thin cervical cancer screening program in our Department in 2011. There were no differences found between studied groups on rate of oral contraceptive or hormonal therapy use, as well as age and tobacco smoking. However, taking into account education and smoking, there was a significant correlation observed. Patients with higher education level smoked less often. The special attention should be paid to promote smoking cessation in the group of women who finished education on elementary level. PMID:23421059

    Background It is difficult to synthesize the vast amount of textual data available from social media websites. Capturing real-world discussions via social media could provide insights into individuals’ opinions and the decision-making process. Objective We conducted a sequential mixed methods study to determine the utility of sparse machine learning techniques in summarizing Twitter dialogues. We chose a narrowly defined topic for this approach: cervical cancer discussions over a 6-month time period surrounding a change in Pap smear screening guidelines. Methods We applied statistical methodologies, known as sparse machine learning algorithms, to summarize Twitter messages about cervical cancer before and after the 2012 change in Pap smear screening guidelines by the US Preventive Services Task Force (USPSTF). All messages containing the search terms “cervical cancer,” “Pap smear,” and “Pap test” were analyzed during: (1) January 1–March 13, 2012, and (2) March 14–June 30, 2012. Topic modeling was used to discern the most common topics from each time period, and determine the singular value criterion for each topic. The results were then qualitatively coded from top 10 relevant topics to determine the efficiency of clustering method in grouping distinct ideas, and how the discussion differed before vs. after the change in guidelines . Results This machine learning method was effective in grouping the relevant discussion topics about cervical cancer during the respective time periods (~20% overall irrelevant content in both time periods). Qualitative analysis determined that a significant portion of the top discussion topics in the second time period directly reflected the USPSTF guideline change (eg, “New Screening Guidelines for Cervical Cancer”), and many topics in both time periods were addressing basic screening promotion and education (eg, “It is Cervical Cancer Awareness Month!

  14. New Molecular Tools for Efficient Screening of Cervical Cancer

    Full Text Available Cytological screening using the Pap-smear led to a remarkable reduction of the mortality of cervical cancer. However, due to subjective test criteria it is hampered by poor inter- and intra-observer agreement. More reproducible assays are expected to improve the current screening and avoid unnecessary medical intervention and psychological distress for the affected women. Cervical cancer arises as consequence of persistent high risk papillomavirus (HR-HPV infections. Expression of two viral oncogenes, E6 and E7, in epithelial stem cells is required to initiate and maintain cervical carcinogenesis and results in significant overexpression of the cellular p16INK4a protein. Since this protein is not expressed in normal cervical squamous epithelia, screening for p16INK4a over-expressing cells allows to specifically identify dysplastic lesions, and significantly reduces the inter-observer disagreement of the conventional cytological or histological tests. Progression of preneoplastic lesions to invasive cancers is associated with extensive recombination of viral and cellular genomes which can be monitored by detection of papillomavirus oncogene transcripts (APOT assay derived from integrated viral genome copies. Detection of integrated type oncogene transcripts points to far advanced dysplasia or invasive cancers and thus represents a progression marker for cervical lesions. These new assays discussed here will help to improve current limitations in cervical cancer screening, diagnosis, and therapy control.

    Full Text Available Objectives: To evaluate the efficacy of 35% orthophosphoric acid, 24% ethylenediaminetetraacetic acid (EDTA and 10% citric acid in the removal of smear layer from retrocavities prepared with ultrasonic retro-tips using scanning electron microscopy. Materials and Methods: Root canals of fifty single-rooted teeth were cleaned, shaped, and obturated with gutta-percha and AH plus sealer. The apical 3 mm of each root was sectioned with a diamond disc and retrograde cavities were prepared with Kis # 1 ultrasonic retro-tips to a depth of 3 mm. Retro cavities in Group I were treated with a gel of 35% orthophosphoric acid for 15 seconds, Group II were treated with a gel of 24% EDTA at neutral pH for 2 minutes, and Group III were treated with a gel of 10% citric acid for 2 minutes, followed by 1 minute rinsing with distilled water for all groups. The samples were prepared for scanning electron microscopic observation. Scoring was performed for the presence of the smear layer on the walls of the retrocavity. Results: In the orthophosphoric acid group, it was observed that all dentinal tubules were open in 70% of the samples. The majority of analyzed samples in EDTA and citric acid group showed dentinal tubules covered with the smear layer. Conclusions: Application of 35% orthophosphoric acid gel for 15 seconds on retrocavities prepared with ultrasonic retro-tips is the most effective means for removal of smear layer.

    Background: Allergic rhinitis (AR) related to local weeds pollen sensitization (Chenopodiaceous family) is the most common cause of respiratory allergy in Kuwait. Local nasal accumulation of different cells typical of allergic inflammation is responsible for clinical symptoms of AR. Although nasal smear for Eosinophils (NSE) is one of the earliest included valuable test in diagnosis of AR, with time is underestimated. Aim: Explore possible correlation of natural pollen allergen stimulation with appearance and quantity of Eosinophils in nasal smear. Methods: A group of randomly selected patients with clinical history suggestive for seasonal AR (SAR), who came to Al Rashed Allergy Center in period from October 2014 to October 2015, obtain Nasal Smear for Eosinophils as a screening test before further diagnostic evaluation. Nasal samples were collected by passing a sterile swab, from each nasal cavity, along the medial surface of the inferior turbinate 2 to 3 times and the specimen smeared on a clear glass slide. Nasal smears were examined by light microscopy after staining with hematoxylin and eosin stain. Skin prick test is performed in all symptomatic patients with a battery of inhalant allergens that include local pollens. The control group was recruited, with their voluntary consent, from the medical stuff with a negative history of any allergic nasal symptoms. In this group we performed only nasal smear for Eosinophils. Air Biology Laboratory Kuwait provided us with daily pollen count. Results: From total 158 study participants, 132 had SAR symptoms and are divided in four groups. Fifth, control, group is non symptomatic. For 38.6% of symptomatic patients NSE were positive, while 45% of these patients have negative SPT. From 62.1% NSE negative patients, 37.8% have negative SPT. Our results showed expected positive correlation of NSE positive patients with pollen season in Kuwait, in SPT positive group. However, presence of Eosinophils in nasal smear was moderate

Objective The aim of this study was to ultrastructurally analyze the surface of intracanal dentine after removal of the smear layer by the solution of doxycycline, citric acid and detergent Tween-80 (MTAD. Methods The study involved 60 single-rooted, extracted, human teeth divided into four groups. All samples were instrumented by a step-back technique and manual K-files, and rinsed during instrumentation by 2% CHX and H2O2. The first group of samples was exclusively rinsed by CHX and H2O2; in the second group, besides using CHX and H2O2, MTAD solution was used for the final irrigation. The samples which were rinsed by distilled water (+ control and the samples rinsed by 5.25% NaOCl and 17% Na EDTA (-control served as control groups. All samples were observed under the scanning electronic microscope JEOL-JSM-5300. The coronary, middle and apex thirds of the radix region were analyzed. Results The obtained results of the SEM analysis showed that the application of 2% chlorhexidine and hydrogen peroxide did not give clear dentine walls, and the smear layer could not be removed completely. The application of the same combination (CHX and H2O2, added by the final MTAD irrigation solution, led to the efficient removal of the smear layer, while the morphological structure of dentine surface remained unchanged. Statistical analysis showed that canal walls in the experimental group with MTAD as the final irrigation were significantly clearer compared to the control group (p<0.001. Conclusion Based on the obtained results, it can be concluded that MTAD is an efficient solution for the final irrigation of the canal system.

    Full Text Available Background: Cervical radiculopathy is a dysfunction of nerve root of the cervical spine where C6& C7 nerve roots are the most commonly affected. It encompasses important symptoms other than pain, such as paresthesia, numbness and muscle weakness in dermatomal or myotomal distribution of an affected nerve root. A multitude of physical therapy interventions have been proposed to be effective in the management of cervical radiculopathy, including mechanical cervical traction, manipulation, therapeutic exercises and TENS. Studies to find out the effectiveness of TENS versus Intermittent Cervical Traction among patients with Cervical Radiculopathy are sparse. Hence the present study was undertaken to find out and compare effectiveness of TENS versus Intermittent Cervical Traction a newer technique towards betterment in treatment of cervical radiculopathy patients. Methodology: 30 patients from Baroda association for the blind (Lions club of Baroda, Subhanpura & Sushrut Physiotherapy Clinic, Akota were chosen based on the inclusion and exclusion criteria. Group A comprised of 15 people with cervical radiculopathy were given TENS with Isometric neck exercises and active neck movements. Group B comprised of 15 people with cervical radiculopathy were given Intermittent Cervical Traction with Isometric neck exercise and active neck movements. VAS Scale & Neck Disability Index (NDI were used as outcome measures pre & post treatment. Results: The pre test evaluation showed that, there is no significant difference (P> 0.05 between the two groups for all the variables measured. The post-test evaluation of both groups showed a very high significance (P< 0.05 within the group for all the outcome measurements. A post-test comparison of measured variables, between the groups showed that the Group A demonstrated a statistically significant (P< 0.05 reduction in pain and Neck Disability Index. Conclusion: From the above study concluded that TENS was more effective

  2. Comparison of Chest X-Ray Findings of Smear Positive and Smear Negative Patients with Pulmonary Tuberculosis

    International Nuclear Information System (INIS)

    Tuberculosis is a chronic pulmonary infectious disease that has affected one-third of the people in the world. It causes nine million new cases and two million deaths per year. Chest radiography associated with Ziehl-Neelsen acid-fast staining procedure significantly helps the diagnosis of pulmonary tuberculosis (PTB). Chest radiography can help the diagnosis of tuberculosis in patients with a negative smear sample result that is mainly diagnosed with delay. In this study, chest X-ray findings of PTB were compared in two groups of smear positive and smear negative patients. In this retrospective descriptive-analytical study, 376 patients who had been confirmed with PTB were referred to Birjand Health Care Center from 2001 to 2006. Out of the 376 patients, 100 patients with a positive smear based on WHO criteria were selected. In addition, among negative smear patients, 100 were selected in whom similar demographic characteristics with positive smear patients were seen. All of them had undergone chest radiographies that were then interpreted by two expert radiologists independently. Moreover, all patients’ sputa were examined by an expert laboratory technician at the reference laboratory of the health center. The obtained data were analyzed by means of frequency distribution table and descriptive statistics using SPSS (version 15) and Chi-square statistical test. Except reticulo-nodular infiltration, the relative frequency of other radiographic findings in positive smear patients were more than negative smear patients; and only differences in calcification variables, mediastinal widening, patchy infiltration and hilar adenopathy were statistically significant (P < 0.05). Based on the results of this study, although radiographic findings are not diagnostic in PTB, they are helpful if the assessment associates with the view of clinical manifestations and sputum smears

    Full Text Available Abstract Background Cervical cancer is the commonest cancer of women in Uganda. Over 80% of women diagnosed in Mulago national referral and teaching hospital, the biggest hospital in Uganda, have advanced disease. Pap smear screening, on opportunistic rather than systematic basis, is offered free in the gynaecological outpatients clinic and the postnatal/family planning clinics. Medical students in the third and final clerkships are expected to learn the techniques of screening. Objectives of this study were to describe knowledge on cervical cancer, attitudes and practices towards cervical cancer screening among the medical workers of Mulago hospital. Methods In a descriptive cross-sectional study, a weighted sample of 310 medical workers including nurses, doctors and final year medical students were interviewed using a self-administered questionnaire. We measured knowledge about cervical cancer: (risk factors, eligibility for screening and screening techniques, attitudes towards cervical cancer screening and practices regarding screening. Results Response rate was 92% (285. Of these, 93% considered cancer of the cervix a public health problem and knowledge about Pap smear was 83% among respondents. Less than 40% knew risk factors for cervical cancer, eligibility for and screening interval. Of the female respondents, 65% didn't feel susceptible to cervical cancer and 81% had never been screened. Of the male respondents, only 26% had partners who had ever been screened. Only 14% of the final year medical students felt skilled enough to use a vaginal speculum and 87% had never performed a pap smear. Conclusion Despite knowledge of the gravity of cervical cancer and prevention by screening using a Pap smear, attitudes and practices towards screening were negative. The medical workers who should be responsible for opportunistic screening of women they care for are not keen on getting screened themselves. There is need to explain/understand the cause

  7. 10-year epidemiological profile changes for cervical and endometrial cancer patients treated by radiotherapy in the Pernambuco state, Brazil

    International Nuclear Information System (INIS)

    Cancer is a worldwide public health problem, its prevention and control are included within 16 strategic objectives of the Brazilian Ministry of Health for the period 2011-2015. Cervical cancer is the fourth most common tumor in the female population, being new 15,590 cases estimated for 2014 according to the Brazilian National Cancer Institute (INCA). Pernambuco is the fifth state with the highest number of cases of cervical cancer and the seventh in cases of endometrial ones, both estimative for 2014. The understanding of the epidemiological profile of these pathologies corroborates strategies for prevention, control and treatment. As Pernambuco has implemented the radiotherapy for cancer treatment since 1998-1999, this work encompassed the comparison of the 1998-1999 epidemiological profile of patients treated by radiotherapy for cervical and endometrial cancer in the State of Pernambuco, Brazil, with 2008-2009 profile - ten years after. Medical record of 490 patients treated at the Center of Radiotherapy of Pernambuco (CERAPE) were compiled according to the patient origin, the affected uterus region, the staging of disease, the type and cell differentiation of the tumor, the age group, and, finally, the realization of hysterectomy as part of the treatment. More than 90% of the patients were affected by cervical cancer in the two investigated periods. For the interval of 1998-1999 the proportion of patients submitted to hysterectomy was quite higher compared to those after ten years. The results also showed a change in the origin of the patients, in which, in 1999, most of the patients were from the capital and the metropolitan area, while, after ten years, patients were mostly from the interior of the State. There was a predominance of squamous cell type tumors in both periods evaluated. For the 1998-1999 interval, tumors were stage 2, moderately differentiated type. Differently, the tumors were mostly stage 3, not differentiated type, for the 2008-2009 period

    Full Text Available Introduction: Atypical glandular cells (AGC are carriers of insufficient nuclear abnormalities for the diagnosis of adenocarcinoma, but exceed the criteria for classification as reactive glandular cells. This is an uncommon diagnosis, which may be associated with neoplastic lesions. Objective: To evaluate the clinical significance of primary cytological diagnosis of AGC through correlation with results of subsequent cyto-histologic examination. Materials and methods: 10 years retrospective study based on cervical cytologic results indicating AGC, classified as "possibly non-neoplastic" or "cannot exclude high-grade intraepithelial lesion". It was performed cyto-histopathological correlation in cases that were submitted to subsequent histopathological examination up to two years after cervical cytology analysis. Results: AGC were reported in 380 (0.06% exams, providing 160 cases with subsequent biopsy. 85 (53.1% of these, presented benign changes and 75 (46.9% neoplastic lesions. From 114 "possibly non-neoplastic" cytological results, 71 (62.3% had benign histological changes, and 43 (37.7% neoplastic lesions, corresponding to a negative predictive value (NPV of 62.3%. In contrast, among the 46 AGC "cannot exclude high-grade intraepithelial lesion" results, 14 (30.4% presented benign changes and 32 (69.6% neoplastic lesions (positive predictive value [PPV] = 69.6%. Discussion: The high rate of cancer associated with the diagnosis of AGC reassures the importance of recognizing these atypical cells in pap smears. The classification of "possibly non-neoplastic" and "cannot exclude high-grade intraepithelial lesion" may suggest the origin of cytological changes. Conclusion: Our results reinforce the importance of adequate follow-up of patients with AGC diagnosis on cervical cytology.

  11. Locally smeared operator product expansions in scalar field theory

    CERN Document Server

    Monahan, Christopher

    2015-01-01

    We propose a new "locally smeared operator product expansion" (sOPE) to decompose non-local operators in terms of a basis of smeared operators. The sOPE formally connects nonperturbative matrix elements determined numerically using lattice field theory to matrix elements of non-local operators in the continuum. These nonperturbative matrix elements do not suffer from power-divergent mixing on the lattice, which significantly complicates calculations of quantities such as the moments of parton distribution functions, provided the smearing scale is kept fixed in the continuum limit. The presence of this smearing scale complicates the connection to the Wilson coefficients of the standard operator product expansion and requires the construction of a suitable formalism. We demonstrate the feasibility of our approach with examples in real scalar field theory.

    One of the most preventable cancers in women is cervical cancer. Pap smear test is an effective screening program; however, it is not conducted very frequently. The aim of this study is explaining the determinants affecting women’s participation in the Pap smear test based on precaution adoption process model with a qualitative approach. This study was a qualitative approach using a Directed Content Analysis methodology which was conducted in 2014. Participants were 30 rural women who participated in this study voluntarily in sarvabad, Iran. Purposive sampling was initiated and continued until data saturation. Semi-structured interviews were the primary method of data collection. Data were analyzed using qualitative content analysis and continuous comparisons. Women`s information and awareness about cervical cancer and Pap smear is insufficient and most of them believed that they were not at risk; however, they perceived the severity of the disease. Some of them had no adequate understanding of the test benefits. They pointed to the lack of time, financial difficulties, fear of test result and lack of awareness as the main barriers against the Pap smear test; however, they did not say that they were not willing to do the test. Findings could help health policy makers to find the right area and purpose to facilitate the participation of women in the Pap smear test. PMID:26755465

  13. Micronuclei as prognostic indicators in oral cytological smears: A comparison between smokers and non-smokers

    2014-01-01

    Full Text Available Background: Micronucleus is a microscopically visible round or oval cytoplasmic chromatin mass in the extra nuclear vicinity, originated from aberrant mitosis, which consists of eccentric chromosomes that have failed to reach spindle poles during mitosis and are used as biomarkers for assessment of DNA damage. Micronuclei are characteristically seen in exfoliated cells of the buccal mucosa and urinary bladder wall in precancerous and cancerous conditions. Oral habits of smoking tobacco or chewing areca nut damage the oral tissues. An assessment of the damage is feasible by the detection of micronuclei in exfoliated cells of the oral tissues using smears. Objectives: The present study was designed to assess the presence or increase of micronuclei in buccal smears of individuals with tobacco habits against a control group of teetotalers. Materials and Methods: Two groups (smokers and non-smokers of 50 individuals each were examined. Buccal smears of all participants were taken using cytobrush and stained with standard Papanicolaou′s (PAP stain. Presence of micronuclei was assessed under Χ100 magnification and a count per 500 cells was determined. The results were analyzed statistically using t-test and Mann-Whitney test. Results: Smears of individuals with tobacco habits showed a significant increase in the total number of micronuclei per 500 cell counts. There was a definite correlation between the occurrence of micronuclei and the frequency and duration of smoking. A paradoxical age related increase in middle-aged groups was also observed. Conclusions: The genotoxic effects of tobacco smoke cause chromosomal damage in the epithelial cells of the oral mucosa and are reflected in the increased micronuclei in smokers. This is present even in the absence of clinically evident changes. This observation is vital in utilization of the micronuclei detection in smears as a prognostic, educational and interventional tool in the management of patients

    Background. Cervical cancer caused by human papilloma virus (HPV) though preventable has claimed the lives of many women worldwide. This study was embarked upon to evaluate the general knowledge and perceptions of Nigerian women on HPV, cervical cancer, and HPV vaccine. Methods. Structured questionnaires were administered to a cross section of 737 women randomly selected from the general population in two southwestern States of Nigeria. Statistical analysis was done using SPSS computer software version 16. A P value >0.05 was considered statistically significant. Results. One hundred and seventy-six (23.9%) of the respondents had knowledge of HPV; 474 (64.3%) are aware of cervical cancer but only 136 (18.5%) know that HPV causes cervical cancer. 200 (27.1%) are aware that there is an HPV vaccine while 300 (40.7%) had knowledge of Pap smear test. Two hundred and sixty (35.3%) of the respondents know that early detection of HPV can prevent cervical cancer and in spite of this, only 110 (14.9%) have taken the Pap smear test before while 151 (20.5%) are not willing to go for the test at all. Conclusions. There is therefore the need to create proper awareness on the HPV and its possible consequence of cervical carcinoma. PMID:26550522

    Full Text Available Abstract The Pap smear is one of the modern success stories in the field of preventive medicine. Since its introduction as a screening test, there has been a dramatic reduction in the incidence of cervical cancer. However, the search for a better screening test continues. The new technologies, including liquid-based cytology (LBC, Human Papilloma Virus (HPV testing and automated or machine-assisted screening have been introduced. However, there is continuous debate about whether society's limited resources are better spent on reaching the underserved rather than on these technologies. Another question is whether these technologies create yet another kind of disparity in delivering preventive care. For example, despite the wide use of LBC (99% of tests submitted to our laboratory are LBC, conventional Pap smears are still used to screen/follow up some women. It is not clear why some providers continue to prefer conventional smear over LBC and what are the barriers for adopting LBC in cervical cancer screening. We hypothesize the lower cost of conventional compared to LBC Pap testing, patient's lower socio-economic indices, a patient's medical history and provider's subspecialty/training all appear to play a role in the choice of using conventional Pap testing rather than LBC. Unintentionally, this choice results in repeat testing, delayed treatment and potentially higher costs than intended. The ultimate goal of this review article is to understand and explore possible barriers and disparities to adopting new technology in cancer screening.

    Full Text Available Background & Objective: Cervical cancer is the second prevalent women cancer in the world. This cancer is found preventable because of having the prolong time before the appearance, its complications and the available proper screening program and possibility of the primary lesion treatment. Since the Health Belief Model is one of the applicable praxeology model in health education to prevent and control of diseases. Therefore, this study was aimed to determine the Health Belief Model components in adopting preventive behaviors in cervical cancer in women. Materials & Methods: This descriptive-analytical study was carried out on 213 married 20-65 year-old women selected by a two-stage sampling method. The data was collected by a valid and reliable questionnaire and interview. This questionnaire based on health belief model correlation (components Perceived Susceptibility and Severity, Perceived Barriers and Benefits, Self-efficacy with behavior survey. The data were analyzed by using descriptive statistics and Mann-Whhitney test, Kruskal-wallis test, and Regression by SPSS software. Results: The mean age of the study group was 40.6 ± 12.1. The results show that 32.5% of them had at least one time examined for Pap smear test out of which only 7.9% of them had this test on a regular interval. Only 12% of them had an adequate knowledge about the cervical cancer and its preventive measure. 90% of them had inappropriate behavior. The average score of knowledge was 6.73± 2.97 which considered as moderate. Regression analysis showed the knowledge (P=0.009, job (P=0.005, perceived barriers (P<0.001 and perceived severity (P=0.036 determine as predictors in the final behavior. Conclusion: Perceived barriers and knowledge behind the strongest predictor of behavior. Educational programs are recommended based on the health belief model with emphasis on reducing barriers and increasing awareness to improve behavior.

However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four “emergent” genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.Keywords: old women, molecular tests, cervical cancer screening, HPV-DNA test, HPV genotyping

  5. Cervical computed tomography

    International Nuclear Information System (INIS)

    This book describes the possibilities of cervical computed tomography with the apparatus available at present. The normal anatomy of the cervical region as it appears in computed tomography is described with special regard to its compartimental structure and functional aspects; this is supplemented by anatomically normal measures obtained from cervical computed tomograms of 60 healthy individuals of different age and both sexes. The morphology of cervical anomalies obtained via CT and of the various acquired cervical disease processes is discussed and illustrated by means of the authors' own observations; the diagnostic value of the findings obtained by CT is discussed, a diagnosis is set up.

    Full Text Available Although anterior cervical instrumentation was initially used in cervical trauma, because of obvious benefits, indications for its use have been expanded over time to degenerative cases as well as tumor and infection of the cervical spine. Along with a threefold increase in incidence of cervical fusion surgery, implant designs have evolved over the last three decades. Observation of graft subsidence and phenomenon of stress shielding led to the development of the new generation dynamic anterior cervical plating systems. Anterior cervical plating does not conclusively improve clinical outcome of the patients, but certainly enhances the efficacy of autograft and allograft fusion and lessens the rate of pseudoarthrosis and kyphosis after multilevel discectomy and fusions. A review of biomechanics, surgical technique, indications, complications and results of various anterior cervical plating systems is presented here to enable clinicians to select the appropriate construct design.

    This paper presents a set of novel structural texture features for quantifying nuclear chromatin patterns in cells on a conventional Pap smear. The features are derived from an initial segmentation of the chromatin into bloblike texture primitives. The results of a comprehensive feature selection experiment, including the set of proposed structural texture features and a range of different cytology features drawn from the literature, show that two of the four top ranking features are structural texture features. They also show that a combination of structural and conventional features yields a classification performance of 0.954±0.019 (AUC±SE) for the discrimination of normal (NILM) and abnormal (LSIL and HSIL) slides. The results of a second classification experiment, using only normal-appearing cells from both normal and abnormal slides, demonstrates that a single structural texture feature measuring chromatin margination yields a classification performance of 0.815±0.019. Overall the results demonstrate the efficacy of the proposed structural approach and that it is possible to detect malignancy associated changes (MACs) in Papanicoloau stain.

    Full Text Available Aim: The purpose of this in-vitro study is to determine the efficacy of various irrigants in removing the smear layer in primary teeth root canals after hand instrumentation. Materials and Methods: The present study consisted of 30 human primary incisors which were sectioned at the cementoenamel junction horizontally. The specimens were divided randomly into four experimental and one control group having six teeth each and each group was treated with the specific irrigant. 5.25% NaOCl, 5.25% NaOCl + 10% EDTA, 6% citric acid, 2% chlorhexidine, saline (control were the irrigants evaluated for efficacy in removal of smear layer. The specimens were split along the longitudinal axis using a chisel after placing superficial grooves in cementum not extending to the root canal. The exposed surface was subjected to scanning electron microscopic analysis to reveal the efficacy of irrigants in removal of smear layer. The representative areas were evaluated twice at 15 days interval by a single evaluator. The scale for the smear layer removal by Rome et al was modified and used in the present study. Results: The pictures from the scanning electron microscopy showed that among the tested irrigants, citric acid has the best efficacy to remove the smear layer without altering the normal dentinal structures, which was supported by the lowest mean smear scores. The pictures from the 10%EDTA + 5.25% sodium hypochlorite group showed that even though it removed the smear layer, it adversely affected the dentine structure. SEM pictures of the other groups like sodium hypochlorite, chlorhexidine revealed that these irrigants does not have the capacity to remove the smear layer in primary teeth. Conclusions: The results of the present study clearly indicate the superior efficacy of 6% citric acid than the other tested irrigants on removing the smear layer in primary teeth root canals.

    In discrete-coordinate quantum models the kinematical observable of position need not necessarily be chosen local (i.e., diagonal). Its smearing is selected in the nearest-neighbor form of a real asymmetric (i.e., crypto-Hermitian) tridiagonal matrix Qˆ. Via Gauss-Hermite illustrative example we show how such an option restricts the class of admissible dynamical observables (sampled here just by the Hamiltonian).

  12. A child presenting with tuberculous spondylitis in a single third cervical vertebra: a case report

    2014-01-01

    Introduction Despite a global reduction in tuberculosis, extrapulmonary tuberculosis is increasing. Spinal tuberculosis remains the commonest form of skeletal tuberculosis. Cervical spine involvement is rare but is the most dangerous form because of diagnostic difficulties and serious residual disability. We report a child who had single vertebral involvement of her third cervical vertebra which is extremely rare. To the best of our knowledge isolated third cervical vertebra involvement in a child by tuberculosis has not been reported previously. Difficulties in obtaining material for histology and bacterial culture from this critical location and how the diagnosis was reached despite these challenges are highlighted. Case presentation A 10-year-old Sinhalese girl developed painful torticollis and ‘cries during sleep’. She had received Bacillus Calmette–Guérin vaccine at birth, was well nourished, and had no loss of weight, anorexia or contact with tuberculosis. A plain radiograph of her neck showed a collapsed third cervical vertebra with no disc involvement. Magnetic resonance imaging confirmed isolated destruction of third cervical vertebra associated with prevertebral soft tissue swelling indenting the thecal sac without cord compression. Her chest radiograph was normal. There was peripheral lymphocytosis, elevated erythrocyte sedimentation rate, negative tuberculin (Mantoux) test, and negative QuantiFERON®-TB GoldIn-Tube assay. Invasive procedures to obtain tissue for histology, smear or culture were perceived by parents as dangerous due to surrounding critical structures and consent was denied. The differential diagnosis included spinal tuberculosis and unifocal Langerhan cell histiocytosis. Nocturnal symptoms and the prevertebral collection of soft tissue (‘cold abscess’) were characteristic of tuberculosis, and nonspecific findings of elevated erythrocyte sedimentation rate and lymphocytosis supported this diagnosis. An incidental finding of a

    The management of cervical disease is changing worldwide as a result of HPV vaccination and the increasing use of HPV testing for cervical screening. However, the impact of vaccination on the performance of HPV based screening strategies is unknown. The SHEVa (Scottish HPV Prevalence in Vaccinated women) projects are designed to gain insight into the impact of vaccination on the performance of clinically validated HPV assays. Samples collated from women attending for first cervical smear who had been vaccinated as part of a national "catch-up" programme were tested with three clinically validated HPV assays (2 DNA and 1 RNA). Overall HR-HPV and type specific positivity was assessed in total population and according to underlying cytology and compared to a demographically equivalent group of unvaccinated women. HPV prevalence was significantly lower in vaccinated women and was influenced by assay-type, reducing by 23-25% for the DNA based assays and 32% for the RNA assay (p = 0.0008). All assays showed over 75% reduction of HPV16 and/or 18 (p HR-HPV was not significantly different in vaccinated vs unvaccinated women. In women with low grade abnormalities, the proportion associated with non 16/18 HR-HPV was significantly higher in vaccinated women (p performance, consequently, longitudinal studies linking HPV status to disease outcomes in vaccinated women are warranted.

    Most upper esophageal malignancies are squamous cell carcinomas, rarely adenocarcinomas arising from Barrett's esophagus and very rarely adenocarcinomas from heterotopic gastric mucosa without evidence of Barrett's especially in the cervical part of the esophagus. We report a case of adenocarcinoma of the polypoid type in the upper esophagus (cervical esophagus) arising from ectopic gastric mucosa, in a 60 year-old man who presented with progressive dysphagia. Accurate diagnosis by esophagogram revealed a large mass in the cervical esophagus; CAT scan showed intraluminal mass at the level of thoracic inlet, esophagogastroscopy showed a fleshy polyp (3.2cm x 3.0cm) at 20 cm from the incisors with a biopsy confirming moderately differentiated adenocarcinoma with no evidence of Barrett's esophagus. Through a left cervical approach and resection of medial third of clavicle, the tumor was removed by partial esophagectomy followed by lymph node dissection, and proved to be T1NOMO, stage I (AJCC staging 6th ed.). Post operatively, the patient received chemoradiation with no evidence of recurrence or metastasis in six years of follow up. It seems this tumor has a much better prognosis than adenocarcinomas arising from Barrett's. To our knowledge only 19 cases have been reported in literature so far. PMID:16110768

    A 50–year old female presented with the chief complaint of a discharge per vaginum, which was there for the past 15 days. A routine PAP smear was received in the Department of Pathology, Government Medical College, Patiala, India. After its fixation and staining, it was examined under the microscope. It showed the Trichomonas vaginalis infection, with the neutrophils forming cannon balls at places. Neutrophils in the PAP smear are a nonspecific finding, particularly if they are low in numbers or if they are seen in the premenstrual and the menstrual phases. The neutrophils which are adherent to the squamous cells are called “cannon balls” or “pus balls”, which are common in the Chlamydia infection. This case is being presented because of the presence of these rare morphological structures i.e. “cannon balls” or “pus balls”. PMID:24086888

  19. Cost Effectiveness of DOTS and Non-DOTS Strategies for Smear-positive Pulmonary Tuberculosis in Beijing

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The cost-effectiveness of DOTS (Directly Observed Treatment, short course) and non-DOTS strategies for smear-positive pulmonary tuberculosis in Beijing was evaluated. Cost calculation was based on the expenses of drugs, chest X-ray films, sputum smears and cultures for the patients. Effectiveness of the intervention was assessed in two aspects: direct benefits to the patients treated and indirect benefits to the others through reduced transmission of tuberculosis; disability adjusted life of year (DALY) was used as an index. The results showed that one DALY could be saved with 45.7 Yuan by DOTS and 471.4 Yuan by non-DOTS. DOTS is a good control strategy for smear-positive tuberculosis.

    Results: A total of 73 patients referred with abnormal pap smears were recruited into the study. The mean age of the patients was 38 yrs (SD ±10. About 45% of the patients interviewed did not have knowledge of Pap smear testing. Both the results of referral Pap smear and repeat pap smear were predominantly low grade squamous intraepithelial lesions (LGSIL or HGSIL. With biopsy results being the gold standard, Liquid based cytology had a higher specificity of 75% when compared with conventional pap smears’ 11%. Conclusions: Even though colposcopy clinical impression has the highest agreement with colposcopy biopsy it’s a diagnostic and not a screening test, hence Liquid based cytology showed better performance as a screening test compared to conventional Pap smear. In general, there was good agreement for cytological results of repeat CPAP and LBC. We therefore recommend that for patients referred with abnormal pap smears requiring a repeat pap smear, liquid based cytology is used due to its higher specificity compared to conventional Pap smear.

    Full Text Available Abstract Background The attendance rate in Estonian cervical cancer screening programme is too low therefore the programme is hardly effective. A cross-sectional population based survey was performed to identify awareness of cervical cancer risk factors, reasons why women do not want to participate in cervical screening programme and wishes for better organisation of the programme. Method An anonymous questionnaire with a covering letter and a prepaid envelope was sent together with the screening invitation to 2942 randomly selected women. Results are based on the analysis of 1054 (36% returned questionnaires. Results Main reasons for non-participation in the national screening programme were a recent visit to a gynaecologist (42.3%, fear to give a Pap-smear (14.3%, long appointment queues (12.9% and unsuitable reception hours (11.8%. Fear to give a Pap-smear was higher among women aged 30 and 35 than 50 and 55 (RR 1.46; 95% CI: 0.82-2.59 and women with one or no deliveries (RR 1.56, 95% CI: 0.94-2.58. In general, awareness of cervical cancer risk factors is poor and it does not depend on socio-demographic factors. Awareness of screening was higher among Estonians than Russians (RR 1.64, 95% CI: 1.46-1.86. Most women prefer to receive information about screening from personally mailed invitation letters (74.8%. Conclusions Women need more information about cervical cancer risk factors and the screening programme. They prefer personally addressed information sharing. Minority groups should be addressed in their own language. A better collaboration with service providers and discouraging smears outside the programme are also required.

    Background A retrospective cohort study was carried out to compare the survival between smear-positive patients and smear-negative multidrug resistant tuberculosis (MDR-TB) patients hospitalised in a specialised TB hospital in Witbank, South Africa. Methods A review of medical records of MDR-TB patients treated from 2001 to 2010 was carried out. Survival time was measured from a patient's date of hospitalisation to the date when the patient died, was last treated at the hospital or the end of the study (whichever came first). All patients who were alive until the end of the study period or lost to follow-up were censored and those who died were considered as failures. Survival patterns were estimated using Kaplan Meier plots, log rank tests and life tables. Cox proportional hazards regression analyses were also conducted. Results The mean age of the 442 MDR-TB patients in the study was 37.7 ± 11.2 years. The incidence rates of mortality were 13.4 and 43.9 per 1000 person-months for smear-negative and smear-positive MDR-TB patients, respectively. Cox proportional hazard regression showed that the predictors of death among MDR-TB patients include HIV co-infection (adjusted Hazard Rate, aHR = 1.89, 95% CI = 1.02-3.52), old age (above 60 years) (aHR = 2.05, 95% CI = 1.04-3.60) and smear positivity at diagnosis (aHR = 3.29, 95% CI = 2.39-4.64). Conclusion The study showed that the probability of survival during the treatment is reduced in MDR-TB patients, who are smear-positive, HIV positive or older than 60 years. Special care should be given to these patients to improve survival. PMID:26954520

    Full Text Available Background : Cervical Lymphadenopathy is one of the commonest clinical presentation in all ages. They are frequently involved in regional and systemic diseases ranging from infection , inflammation , immune related and neoplastic conditions. Fine needle aspiration cytology to assess the cytomorphology of Lymph nodes is regularly done by Pathologists. FNAC helps to diagnose multiple lesions avoiding biopsy. It is a simple and rapid diagnostic test , econ omic , primary investigation with minimal trauma easily carried out in OPD. Objective : To study the role of FNAC in evaluation of cervical Lymphadenopathy MATERIAL AND METHOD: This retrospective study was conducted from records of 6 years from Jan.2005 - Dec. 2010. All patients who presented with enlarged cervical lymph node/nodes were included in the study. Written informed consent was obtained from all patients. Total 1195 cases of cervical lymphadenopathy were studied. Hypocellular and acellular smears were discarded. FNAC was done with 22 - 24 gauge disposable needle using 20 ml. syringe. The smears were dried and stained with MGG. RESULTS: Total 1195 cases of cervical lymphadenopathy were studied. Maximum number of cases were 21 - 30 years age group. Males were more than the females. Patients below 15 years constituted 32.5 % cases. Maximum cases reported were of Tubercular lymphadenitis followed by Reactive Lymphadenitis. Squamous cell carcinoma was the commonest metastatis.02 cases were discarded due to hypoce llularity and non - availability of clinical details. CONCLUSION: FNAC is first line diagnostic , cost effective and easy procedure yielding quick and mostly definite results. Biopsy now follows FNAC.

    Worldwide, multidrug resistance (MDR TB) is a serious issue. It has increased over the last decade. Re-treatment completed sputum smear positive cases have much higher incidence of MDR- TB as compared to primary MDR - TB. Objective: To estimate the incidence of drug resistance pattern among AFB smear positive re-treatment completed cases. Study Design: Evidence based prospective study. Study Setting: Institute of Chest Medicine, Mayo Hospital Lahore, Tertiary care hospital affiliated with King Edward Medical University, Lahore, Pakistan. Methodology: A total 50 (Male 22, Female 28) pulmonary TB patients who had completed Re- treatment regimen in the past and are still sputum smear positive for acid fast Bacilli were included in the study. Three consecutive sputum specimens were collected at Aga Khan University collection center at Lahore. The specimen were sent to Aga Khan University Lab Karachi for AFB smear, culture and drug sensitivity both for essential and reserve drugs. Reports for AFB smear were received within a week, while culture and drug sensitivity' reports after 6 weeks. Reports data was analyzed for essential and reserve anti tuberculous drug sensitivity for mycobacterium tuberculosis. Results: Data Analysis revealed MDR TB in 31(62%) patients which include 11 males and 23 females. Individual drug resistance to essential drugs was INH - 62%, Rifampicin - 68%, Ethambutol - 24%, PZA - 25% and Streptomycin - 21 %. Poly drug resistance was determined in' 38% cases. Individual drug resistance to reserve drugs - kanamycin, Amikacin, ofloxacin, Ethionamide and PAS was 4%, 4%, 36%, 10% and 2% respectively. Conclusion: There is a very high proportion of MDR TB in sputum smear AFB positive retreatment cases. Suggestion: Comprehensive measures including DO- TS PLUS are needed to control MDR TB in Pakistan. (author)

METHODS: Cross-sectional study in a sample of 5,485 women (15-65 years old who self-referred to cervical cancer screening in Sao Paulo and Campinas, Southeastern Brazil, between February 2002 and March 2003. A behavioral questionnaire was applied and cervical specimens were obtained for testing by Pap smears or liquid-based cytology. Women who had abnormal cytology were referred for colposcopic examination and, if abnormal, for cervical punch biopsy. To explore factors associated to cervical abnormalities Pearson's chi-was conduted square test at a 5% significance level. RESULTS: Cytological abnormalities were found in 354 women (6.4% and included 41 high-grade squamous intra-epithelial lesions and 3 carcinomas; 92.7% were normal results. Colposcopy was performed in 289 women, and 145 (50.2% showed abnormal results. Punch biopsies showed 14 cervical intraepithelial neoplasias grade 3 and 4 carcinomas. Previous Pap smears were reported in all women who had cytology suspected of carcinoma, 97.6% of those with high-grade squamous intra-epithelial lesions, all women with histological diagnosis of carcinoma and 92.9% of those who had cervical intraepithelial neoplasias grade 3 histologically. Previous Pap smear in the last tree years was reported by 86.5% and 92.8% of women with abnormal cytology and biopsy, respectively. CONCLUSIONS: There was no statistically significant difference regarding the number of Pap tests and time since their last test between women with histologically diagnosed carcinoma and cervical intraepithelial neoplasia grade 3 compared with those with normal cytology.

    Despite the undisputed and impressive success which has been achieved since the 1960s by cervical cytology in the fight against cervical cancer and its precursor stages, during which the mortality rate in industrialized countries over the last 40 years has been reduced by two-thirds to three-quarters, a perfect and error-free screening procedure is still a long way off and will probably never be reached. There are two main reasons for this, the lack of adequate coverage and suboptimal quality and assessment of smears. Two screening procedures are in use Europe, an opportunistic and an organized system. Both systems have many advantages but also disadvantages. In organized programs the coverage is higher (up to 80%), although similar numbers are also achieved by non-organized programs over a 3-year cycle, even if they cannot be so exactly documented. The decision on which system is used depends on the health system of the country, public or non-public, and many other national circumstances. However, in both systems prerequisites for a satisfactory result is a high quality in the sampling technique, the processing and the assessment. Therefore, several guidelines have been introduced by state and medical societies for internal and external quality assurance. New technologies, such as thin-layer cytology or automation for replacement or support of conventional cytology liquid-based cytology proved not to be superior enough to justify the high costs of these systems. The recognition of the strong causal relationship between persistent infection with high-risk human papillomavirus (HPV) types and cervical cancer and its precursors has resulted in the development of comparably simple tests. Primary screening using HPV typing alone is not recommended in opportunistic screening due to the low specificity but high sensitivity because it leads to many clinically irrelevant results which place women under stress. In organized screening HPV testing is always and only possible

    Full Text Available BACKGROUND: Cervical cancer, common among Indian women is now considered as preventable. OBJECTIVES: To find out the knowledge regarding prevention of cervical cancer, practices towards its prevention and its determinants among women attending a tertiary care centre of Tripura. METHODOLOGY: A hospital based cross-sectional study was conducted during 8th April 2014 to 17th May 2014 using a pretested structured interview schedule among 289 women attending the Gynaecology O.P.D of AGMC & G.B.P Hospital recruited by systematic random sampling. STATISTICAL ANALYSIS: Data entry and analysis were performed in computer using SPSS 15. Descriptive statistics and Chi-square test were used for presenting data and testing the significance. RESULTS: Cervical cancer was known as preventable to 61.9 % of the study women. About 59.2% women knew multiple sex partners, 42.6% knew exposure to sexual intercourse at early life, 72.7 % knew poor sexual hygiene and 26.0% knew heredity as the risk factors for getting cervical cancer. Approximately 16.3% women knew about the vaccine against cervical cancer, 59.86% knew it as a treatable disease and 15.57% have heard about PAP smear test. Only 10.38 % of the study women underwent PAP smear test and 0.3 % were vaccinated against cervical cancer. Regarding cervical cancer, 29.41% women knew either by studying or from the media, 22.49% from friends and relatives and only 16.26% from health workers whereas 31.84% were unaware. Literacy of the women was found to be significantly associated with their awareness and practices regarding prevention of cervical cancer. CONCLUSION: Knowledge regarding possibility of early diagnosis, preventability and treatability of cervical cancer is found to be low among women. Role of health workers for making people aware was inadequate; hence IEC and BCC activities need acceleration for awareness generation and motivation for undergoing vaccination and screening for cervical cancer.

    Full Text Available Objectives: To assess baseline knowledge of cancer cervix, screening and practice of Pap smear screening among Sikkimese staff nurses in India. Materials and Methods: Between April 2012 and February 2013, a predesigned, pretested, self -administered multiple responses questionnaire survey was conducted among staff nurses′ working in various hospitals of Sikkim. Questionnaire contained information about their demographics, knowledge of cervical cancer, its risk factors, screening methods, attitudes toward cervical cancer screening and practice of Pap smear amongst themselves. Results: Overall, 90.4% nurses responded that they were aware of cancer cervix. Three quarter of the staff nurses were not aware of commonest site being cancer cervix in women. Of the 320 participants, who had heard of cancer cervix, 253 (79.1% were aware of cancer cervix screening. Pap smear screening should start at 21 years or 3 years after sexual debut was known to only one-third of the nursing staff. Age was found to be a significant predictor of awareness of Pap smear screening among nursing staff. Awareness was significantly more prevalent among older staff (P < 0.007. Married nursing staffs were significantly more likely to be aware of screening methods, and nursing staff of Christian and Buddhist religion were 1.25 times and 2.03 times more likely to aware of screening methods than Hindu religion respectively. Only 16.6% nurses, who were aware of a Pap smear (11.9% of the total sample, had ever undergone a Pap smear test. Most common reason offered for not undergoing Pap smear test were, they felt they were not at risk (41%, uncomfortable pelvic examination (25% and fear of a bad result (16.6%. Conclusion: Knowledge of cancer cervix, screening and practice of Pap smear was low among Sikkimese nursing staff in India. There is an urgent need for re-orientation course for working nurses and integration of cervical cancer prevention issues in the nurses′ existing

    they actually are; as long as there is significant legal and financial risk to actually measuring the true sensitivity; and as long as fictitious measures of performance are not only advocated but mandated; the confluence of incentives will ensure that the true sensitivity of the test will never be measured on a routine basis. Despite all of this, it is possible that cervical cytology screening may, in fact, already be performing at an optimal level. Being able to measure this operating performance may not effect any improvement to the overall process. The ultimate arbiter in this debate will always be the demonstration of a reduction of cervical cancer morbidity and mortality with any new measure implemented. At the present time, there is only one solution to the quality control issue; a force from outside the system must change the balance of the aforementioned incentives. The promise of data from European experiences with rapid rescreening may show that this method is effective and accurate. Such data might make the current methods that are in use in the United States more open to change. So yes, the answer is that "bad" data may be worse than no data at all. The bad data that we have been collecting for more than a decade is as effective a trap as anyone could have devised to ensure that actually measuring the performance of cervical smear interpretation does not happen. The only question that remains is, "How we will be able to escape?" PMID:14560535

    Cytologic diagnoses in the oral region are very difficult due to the small amount of cells in smears, which are also exposed to many stimulating factors and often show atypical changes. Galectin-1 (Gal1) is a β-galactoside binding protein that modulates tumor progression. Gal1 is very weakly expressed in normal cells, but is often overexpressed in neoplastic lesions. The aim of the present study was to determine whether it is possible to differentiate reactive changes from neoplastic changes in oral cytology smears based on the expression of Gal1. A total of 155 tissue biopsy specimens and 61 liquid-based cytology specimens were immunostained by an anti-Gal1 antibody, and Gal1 expression levels were subsequently evaluated. These samples consisted of oral squamous cell carcinomas, epithelial dysplasia, and oral mucosal diseases. The positive and negative expressions of Gal1 were examined in 37 specimens collected by scalpel and cytobrush biopsy. The sensitivity, specificity, and positive predictive value of Gal1 were also evaluated in smears. In tissue sections, the positive ratio of Gal1 in neoplastic lesions was high (72.3%). In cytology specimens, the positive ratio of Gal1 was higher in neoplastic lesions (79.0%) than in those negative for intraepithelial lesion or malignancy (22.2%). A correlation was found between immunocytochemical Gal1 expression and immunohistochemical Gal1 expression (P < .001). The sensitivity (75.0%), specificity (75.0%), and positive predictive value (91.3%) of Gal1 were also high in smears. In conclusion, Gal1 may be a useful marker for determining whether morphologic changes in cells are reactive or neoplastic. PMID:26980012

  18. Quality control in screening programs for cervical cancer

    International Nuclear Information System (INIS)

    The malignancy of the cervix is one of the few locations avoidable cancers, if detected before it progresses to the infiltration. The most efficient way of early detection is through a screening program to provide women undertaking a regular and quality Pap smear. If this test results abnormal, the program offers easier access to specialized care, effective treatment, and follow-up. The objective of this article is to present usefulness of methods for quality control used in screening programs for cervical cancer to detect their inadequacies. Here are some factors and conditions that must be considered in each of the steps to take, for a cervical cancer screening program to be successful and to meet the objectives proposed in reducing mortality due to this cause. This document contains some useful indexes calculated to ensure quality throughout the process. There should be the measurement of quality throughout the screening process that allows collecting of reliable data as well as correcting deficiencies

    2015-01-01

    Full Text Available Cervical cancer is the second most common female cancer worldwide and a disease of concern due to its high rate of incidence of about 500,000 women annually and is responsible for about 280,000 deaths in a year. The mortality and morbidity of cervical cancer are reduced through mass screening via Pap smear, but this technique suffers from very high false negativity of around 30% to 40% and hence the sensitivity of this technique is not more than 60%. Electrical bioimpedance study employing cytosensors over a frequency range offers instantaneous and quantitative means to monitor cellular events and is an upcoming technique in real time to classify cells as normal and abnormal ones. This technology is exploited for label-free detection of diseases by identifying and measuring nonbiological parameters of the cell which may carry the disease signature.

  20. Clinico-pathological profile and treatment outcome in smear negative pulmonary tuberculosis patients at a teaching hospital

    International Nuclear Information System (INIS)

    Tuberculosis remains the single highest contributor to the world's morbidity and mortality. Early diagnosis and prompt treatment is essential to prevent its transmission. To see the treatment response of anti tuberculosis drugs in smear negative patients and study the predictors of culture positive among smear negative tuberculosis patients. Ninety four sputum smear negative patients clinically and radiologically suggestive of tuberculosis were selected. These patients were put on anti tuberculosis drugs without waiting for their culture results. They were then followed for 8 months to see their treatment outcome. A total of 94 smear negative patients were selected and given anti tuberculosis treatment. Of these 37(39%) were culture positive and 57(61%) were culture negative. Of the 37 culture positive patients 36(97%) showed clinical or radiological improvement as compared to 46(81%) out of 57 in culture negative cases. Symptoms of cough with sputum production was significantly associated with culture positivity. On x-ray chest moderate lesion with diffuse infiltration was more common finding in 64% while extensive and cavitatory lesion was seen in 24% of all cases. Association of extensive and cavitatory lesion were seen in culture positive group. Response to anti tuberculosis drugs in sputum smear negative tubercolosis suspects was found to be effective in majority of the patients. Cough, sputum and extensive cavitatory lung lesion were the predictors of culture positive cases. There is need to train physicians on the use of anti tuberculosis therapy in smear negative suspected pulmonary tuberculosis cases, especially if they have productive cough and cavitatory lung lesions.

    Full Text Available Abstract Background The National Cervical Screening Program in Australia currently recommends that women aged 18–69 years are screened with conventional cytology every 2 years. Publicly funded HPV vaccination was introduced in 2007, and partly as a consequence, a renewal of the screening program that includes a review of screening recommendations has recently been announced. This study aimed to provide a baseline for such a review by quantifying screening program resource utilisation and costs in 2010. Methods A detailed model of current cervical screening practice in Australia was constructed and we used data from the Victorian Cervical Cytology Registry to model age-specific compliance with screening and follow-up. We applied model-derived rate estimates to the 2010 Australian female population to calculate costs and numbers of colposcopies, biopsies, treatments for precancer and cervical cancers in that year, assuming that the numbers of these procedures were not yet substantially impacted by vaccination. Results The total cost of the screening program in 2010 (excluding administrative program overheads was estimated to be A$194.8M. We estimated that a total of 1.7 million primary screening smears costing $96.7M were conducted, a further 188,900 smears costing $10.9M were conducted to follow-up low grade abnormalities, 70,900 colposcopy and 34,100 histological evaluations together costing $21.2M were conducted, and about 18,900 treatments for precancerous lesions were performed (including retreatments, associated with a cost of $45.5M for treatment and post-treatment follow-up. We also estimated that $20.5M was spent on work-up and treatment for approximately 761 women diagnosed with invasive cervical cancer. Overall, an estimated $23 was spent in 2010 for each adult woman in Australia on cervical screening program-related activities. Conclusions Approximately half of the total cost of the screening program is spent on delivery of primary

    In this study the performance of various intelligent methodologies is compared in the task of pap-smear diagnosis. The selected intelligent methodologies are briefly described and explained, and then, the acquired results are presented and discussed for their comprehensibility and usefulness to medical staff, either for fault diagnosis tasks, or for the construction of automated computer-assisted classification of smears. The intelligent methodologies used for the construction of pap-smear classifiers, are different clustering approaches, feature selection, neuro-fuzzy systems, inductive machine learning, genetic programming, and second order neural networks. Acquired results reveal the power of most intelligent techniques to obtain high quality solutions in this difficult problem of medical diagnosis. Some of the methods obtain almost perfect diagnostic accuracy in test data, but the outcome lacks comprehensibility. On the other hand, results scoring high in terms of comprehensibility are acquired from some methods, but with the drawback of achieving lower diagnostic accuracy. The experimental data used in this study were collected at a previous stage, for the purpose of combining intelligent diagnostic methodologies with other existing computer imaging technologies towards the construction of an automated smear cell classification device.

    We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance ({rho} > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury.

    Cervical cancer screening by Papanicolaou (Pap) smear lowers the incidence and provides early detection of cervical cancer and is a preventative health care measure that should be available on a regular basis to all women at risk. As the population of ethnic women increases, it is important to assess whether these women are aware of and are utilizing this health service. A self-administered questionnaire was completed by 124 South Asian women, aged 18 to 60 years. Sixty-two South Asian students were selected from a university setting and 62 Tamil women were selected from a community center for South Asian women. This study examined the knowledge and use of Pap smears in South Asian women in Canada, and whether their level of acculturation or formal education influenced whether they know about and receive Pap smears. Low level of knowledge about the Pap test and a low prevalence of Pap testing behaviour was significantly correlated (p students were significantly more acculturated than Tamil women (p knowledge and prevalence of cervical cancer screening among South Asian women. This study highlights the need for educational interventions in Canada directed to ethnic women especially from South Asia. PMID:11868960

    Cervical cancer is one of the most frequent cancers in women worldwide. Persistent infection with a human papillomavirus (HPV) is the main cause for cervical cancer. Vaccination and Pap smear screening are the best methods for prevention of the disease. The objective of this cross-sectional study was to assess the knowledge and views of upper secondary school female students in Kuala Lumpur, Malaysia, toward prevention of cervical cancer. This study was conducted from April 2009 to September 2009 in 8 schools in Kuala Lumpur area using pre-tested and validated questionnaires. Results indicated that the respondents had low knowledge of cervical cancer and its prevention although the majority of students (80.4%) had heard about the disease. The level of knowledge of cervical cancr and its prevention was significantly higher among students from the science stream (pstudents from the art stream. Most students (69.3%) agreed to take the vaccination if the service was available in schools. A high percentage of students (82.2%) agreed that the vaccination should be compulsory to the students. In conclusion, most students had low knowledge of cervical cancer and its prevention but they had positive attitude toward vaccination and agreed that vaccination should be compulsory. Therefore, suitable educational programmes should be developed to improve the knowledge of secondary school students on the prevention of cervical cancer. PMID:23725172

Material and Method: In 210 patients (%42,7 female, %57,6 male, mean age:40,5 ± 16,1 with smear positive and negative PTB we retrospectively analyzed the relation between radiographic findings, TST and BCG. We separated the patients into three groups as mild, moderate and severe according to their radiologic involvement and compared the radiologic extension with tuberculin skin test results. We also compared the degree of sputum smear positivity with tuberculin skin test results. Results: According to the evaluation of radiological findings of the patients, high risk is detected in 58(67,4% patients in smear-positive group and 28(32,6% patients in smear-negative group and statistically valuable relation between smear positivity and radiological findings of the patients is seen (p:0,001. According to the results of TST of the patients, high risk is detected radiologically in 53(61,6% cases of TST-negative group, 33(38,4% cases of TST-positive group and statistically valuable relation between TST results and radiological findings of the patients is seen (p:0,001. A valuable difference between BCG results and radiological findings is not seen. Discussion: It is concluded that radiology is beneficial for diagnosis especially in cases which are without bacilli and suspicious for tuberculosis and TST is shown that it can be beneficial for determining the immunity against to mycobacterium tuberculosis.

    Full Text Available Abstract Background Cancer screening rates in Korea for five cancer types have increased steadily since 2002. With regard to the life-time cancer screening rates in 2009 according to cancer sites, the second highest was breast cancer (78.1% and the third highest was cervical cancer (76.1%. Despite overall increases in the screening rate, disparities in breast and cervical cancer screening, based on sociodemographic characteristics, still exist. Methods Data from 4,139 women aged 40 to74 years from the 2005 to 2009 Korea National Cancer Screening Survey were used to analyze the relationship between sociodemographic characteristics and receiving mammograms and Pap smears. The main outcome measures were ever having had a mammogram and ever having had a Pap smear. Using these items of information, we classified women into those who had had both types of screening, only one screening type, and neither screening type. We used logistic regression to investigate relationships between screening history and sociodemographic characteristics of the women. Results Being married, having a higher education, a rural residence, and private health insurance were significantly associated with higher rates of breast and cervical cancer screening after adjusting for age and sociodemographic factors. Household income was not significantly associated with mammograms or Pap smears after adjusting for age and sociodemographic factors. Conclusions Disparities in breast and cervical cancer screening associated with low sociodemographic status persist in Korea.

    Full Text Available BACKGROUND: HIV-infected women are at increased risk for developing cervical cancer. Women living in resource-limited countries are especially at risk due to poor access to cervical cancer screening and treatment. We evaluated three cervical cancer screening methods to detect cervical intraepithelial neoplasia grade 2 and above (CIN 2+ in HIV-infected women in South Africa; Pap smear, visual inspection with 5% acetic acid (VIA and human papillomavirus detection (HPV. METHODS: HIV-infected women aged 18-65 were recruited in Johannesburg. A cross-sectional study evaluating three screening methods for the detection of the histologically-defined gold standard CIN-2 + was performed. Women were screened for cervical abnormalities with the Digene HC2 assay (HPV, Pap smear and VIA. VIA was performed by clinic nurses, digital photographs taken and then later reviewed by specialist physicians. The sensitivity, specificity and predictive valves for CIN-2 + were calculated using maximum likelihood estimators. RESULTS: 1,202 HIV-infected women participated, with a median age of 38 years and CD4 counts of 394 cells/mm(3. One third of women had a high grade lesion on cytology. VIA and HPV were positive in 45% and 61% of women respectively. Estimated sensitivity/specificity for HPV, Pap smear and VIA for CIN 2+ was 92%/51.4%, 75.8%/83.4% and 65.4/68.5% (nurse reading, respectively. Sensitivities were similar, and specificities appeared significantly lower for the HPV test, cytology and VIA among women with CD4 counts ≤200 cells/mm(3 as compared to CD4 counts >350 cells/mm(3. CONCLUSIONS: Although HPV was the most sensitive screening method for detecting CIN 2+, it was less specific than conventional cytology and VIA with digital imaging review. Screening programs may need to be individualized in context of the resources and capacity in each area.

    Full Text Available Background: Data from Egyptian studies provide widely varying estimates on the prevalence of preinvasive cervical lesions. The aim of this study was to estimate the rate of cervical intraepithelial neoplasia (CIN   in Egyptian women living in Alexandria to clarify the need for implementing a national organized screening program and a vaccination program in our community. Materials and Methods: The study was conducted over a 6 years period and covered the different socioeconomic levels to have a representative sample for women living in Alexandria. All women included did not have any cervical disorder related complaints. Conventional Pap smears were obtained and diagnosed using the Bethesda system. Women with abnormal Pap smears were managed according to the 2006 consensus guidelines within the available facilities. Persistent abnormal cytological results were referred for colposcopic biopsy. Histological results were grouped into: Reactive changes, CIN 1, CIN 2/CIN 3 and adenocarcinoma in-situ (AIS. Results: Out of the 6173 smears included in the study 6072 (98.36% were normal and only 101 (1.63% were abnormal. After colposcopic biopsies, 0.08% had CIN 1, 0.03% had CIN 2, 3 and 0.01% had AIS. Conclusion: We concluded that cervical cancer screening programs, although life-saving for a number of women, are not a sufficiently high priority in our community. Money for national health screening programs should preferably be directed more towards recruiting women for breast cancer screening, since breast cancer accounts for about 33% of all female cancers in Egypt ranking number one, while cervical cancer ranks number 13.

    Full Text Available Abstract Background Knowledge of the distribution of human papillomavirus (HPV genotypes among women with cervical lesion and in invasive cervical cancer is crucial to guide the introduction of prophylactic vaccines. There is no published data concerning HPV and cervical abnormalities in Sudan. This study aimed to define the prevalence of HPV and its subtypes in the cervical smears of women presenting with gynecological complains at Omdurman Military Hospital, Sudan. During the period between March 2003 and April 2004, 135 cervical smears collected from these women, were screened using cytological techniques, and analysed by PCR for (beta-globin and HPV DNA using gel electrophoresis and ELISA. Results Of these 135 smears, there were 94 (69.3% negative, 22 (16.3% positive for inflammation, 12(8.9 mild dyskaryosis, 5 (3.7 moderate dyskaryosis and 2 (1.8 severe dyskaryosis. There were 60.7% ß. globin positive samples for HPV indicating DNA integrity. HPV DNA was identified in three samples (2.2% by gel electrophoresis and. was positive in four samples (2.9% as single and multiple infections by PCR-ELISA. The high risk HPV types 16 and 58 were identified in one sample as a mixed infection. The low risk HPV types 40 and 42 were also found as a mixed infection in another patient. HPV types 58 and 42 were identified in the other two patients. Conclusion HPV type distribution in Sudan appears to differ from that in other countries. The HPV genotypes identified were not associated with cancer.

    The primary objective of this study was to assess the knowledge of medical students and determine variation between different cultural groups. A secondary aim was to find out the willingness to pay for cervical cancer vaccination and the relationships between knowledge and attitudes towards Human Papillomavirus vaccination. A cross-sectional survey was conducted in a private medical university between June 2014 and November 2014 using a convenient sampling method. A total of 305 respondents were recruited and interviewed with standard questionnaires for assessment of knowledge, attitudes and practice towards human papilloma virus and their willingness to pay for HPV vaccination. Knowledge regarding human papilloma virus, human papilloma virus vaccination, cervical cancer screening and cervical cancer risk factors was good. Across the sample, a majority (90%) of the pupils demonstrated a high degree of knowledge about cervical cancer and its vaccination. There were no significant differences between ethnicity and the participants' overall knowledge of HPV infection, Pap smear and cervical cancer vaccination. Some 88% of participants answered that HPV vaccine can prevent cervical cancer, while 81.5% of medical students said they would recommend HPV vaccination to the public although fewer expressed an intention to receive vaccination for themselves.

    Full Text Available Aim: The aim of this in vitro study is to compare the smear layer removal efficacy of different irrigating solutions at the apical third of the root canal. Materials and Methods: Forty human single-rooted mandibular premolar teeth were taken and decoronated to standardize the canal length to 14 mm. They were prepared by ProTaper rotary system to an apical preparation of file size F3. Prepared teeth were randomly divided into four groups (n = 10; saline (Group 1; negative control, ethylenediaminetetraacetic acid (Group 2, BioPure MTAD (Group 3, and QMix 2 in 1 (Group 4. After final irrigation with tested irrigants, the teeth were split into two halves longitudinally and observed under a scanning electron microscope (SEM for the removal of smear layer. The SEM images were then analyzed for the amount of smear layer present using a three score system. Statistical Analysis: Data are analyzed using the Kruskal-Wallis test and Mann-Whitney U-test. Results: Intergroup comparison of groups showed statistically significant difference in the smear layer removal efficacy of irrigants tested. QMix 2 in 1 is most effective in removal of smear layer when compared to other tested irrigants. Conclusion: QMix 2 in 1 is the most effective final irrigating solution for smear layer removal.

    Full Text Available Aim: The purpose of this study is to evaluate and compare the efficacy of 17% EDTA, 18% etidronic acid, and 7% maleic acid in smear layer removal using scanning electron microscopic image analysis. Materials and Methods: Thirty, freshly extracted mandibular premolars were used. The teeth were decoronated to obtain working length of 17mm and instrumentation up to 40 size (K file with 2.5% NaOCl irrigation between each file. The samples were divided into Groups I (17% ethylenediaminetetraacetic acid (EDTA, II (18% etidronic acid, and III (7% maleic acid containing 10 samples each. Longitudinal sectioning of the samples was done. Then the samples were observed under scanning electron microscope (SEM at apical, middle, and coronal levels. The images were scored according to the criteria: 1. No smear layer, 2. moderate smear layer, and 3 heavy smear layer. Statistical Analysis: Data was analyzed statistically using Kruskal-Wallis analysis of variance (ANOVA followed by Mann-Whitney U test for individual comparisons. The level for significance was set at 0.05. Results: The present study showed that all the three experimental irrigants removed the smear layer from different tooth levels (coronal, middle, and apical. Final irrigation with 7% maleic acid is more efficient than 17% EDTA and 18% etidronic acid in the removal of smear layer from the apical third of root canal.

    We study the formation of the (noncommutative) Schwarzschild black hole from collapsing shell of the generalized matters containing polytropic and Chaplygin gas. We show that this collapsing shell depending on various parameters forms either a black hole or a naked singular shell with the help of the pressure. Furthermore, by considering the smeared gravitational sources, we investigate the noncommutative black holes formation. Though this mild noncommutative correction of matters cannot ultimately resolve the emergence of the naked singularity, we show that in some parameter region the collapsing shell evolves to a noncommutative black hole before becoming a naked singular shell.

    Full Text Available Background: Cervical disc replacement is becoming an increasingly popular treatment option for cervical myelopathy. It retains motion at the affected segment, unlike anterior cervical discectomy and fusion. The aim of this study is to assess the outcomes of a series of patients who underwent Activ C disc replacement for cervical myelopathy. Materials and Methods: A series of patients at the above Trust with clinical and radiological evidence of cervical myelopathy who were suitable for cervical disc replacement from 2007 to 2009 were included. Implants were inserted by one of two consultant surgeons {IMS, MO′M}. Patients were assessed preoperatively and at six, 12 and 24 months, postoperatively, with a visual analogue score (VAS for neck and arm pain severity and frequency, the Neck Disability Index questionnaire (NDI and the Centre for Epidemiologic Studies Depression questionnaire (CES-D. Results: Ten patients underwent surgery between May 2007 and July 2009, 6 women, and 4 men. Average age was 54 years (40-64. Disc levels replaced were: four at C4-5; eight at C5-6; seven at C6-7. Three patients had one disc replaced, five patients had two discs replaced, and two patients had three discs replaced. The VAS for neck pain improved from 5.9 pre-operatively to 1.4-24 months postoperatively and the VAS arm pain improved from 5.4 to 2.6. The NDI improved from 51% preoperatively to 26.8% at 24 months postoperatively. The CES-D showed a slight increase from 19.5 preoperatively to 21.7 at 24 months, postoperatively. Conclusion: Cervical decompression and disc replacement improves pain and function in patients with cervical myelopathy. This benefit is maintained at 24 months post op, with no cases requiring revision.

  14. Environmental exposure to cooking oil fumes and cervical intraepithelial neoplasm

    International Nuclear Information System (INIS)

    The fumes from cooking oil, similar to cigarette smoke, contain numerous carcinogens such as polycyclic aromatic hydrocarbons, aromatic amines, nitro-polycyclic aromatic hydrocarbons, etc. In this study, we examined the association between exposure to cooking oil fumes and the risk of cervical intraepithelial neoplasm. The study population in this nested case-control study consisted of women above the age of 19 years living in Chia-Yi County, located in the southwestern Taiwan, who had received pap smear screening between October, 1999, and December, 2000 (n=32,466). The potential cases were women having lesions greater than cervical intraepithelium neoplasm II (≥CIN2) reconfirmed by cervical biopsy (n=116). The potential controls (case: control=1:2) were age-matched (±2 years) and residence-matched women who had normal pap smears within 6 months of the cases. In total, 100 cases and 197 controls were completely interviewed by public health nurses about cooking methods, ventilation, and other potential risk factors. Women who cooked at home in a kitchen (n=269) without the presence of a fume extractor at least once a week between the ages of 20 and 40 had a 2.29 times higher risk [95% confidence interval (CI)=1.08-4.87] of developing cervical intraepithelial neoplasm than those who did not cook once a week in such a kitchen during the same age span, after adjusting for other potential confounders. This finding was further strengthened by the finding that women who did not use the fume extractors had a 2.47 times higher risk (95% CI=1.15-5.32) of developing cervical intraepithelial neoplasm than women who cooked in kitchens with fume extractors that were always switched on while cooking. We also found a joint protective effect of fume extractor use among women older than 40 years (n=202) if they used the extractors during both age spans of their lives, ages 20-40 and >40 years. Comparing our findings on women more than 40 years old who used fume extractors during

    Full Text Available Infection with genital herpes simplex virus (HSV remains a common viral sexually transmitted disease, often subclinical and a major worldwide problem of women of reproductive age group. Herpes cervicitis is an unusual presentation of Herpes simplex virus infection in females. The finding of herpes cervicitis on routine pap smear of an asymptomatic woman on Intrauterine contraceptive device still further supports the need for increased awareness on the possibility of Herpes simplex virus infection among women, particularly those on Intrauterine contraceptive device. The index case is a 28 years old Nigerian female who was referred to our Special Treatment Clinic on account of an abnormal pap smear cytology which was in keeping with Herpes cervicitis. There was no history of genital ulcer in this patient; however ELISA for HSV 2 IgM was positive in her. We therefore describe a case of herpes cervicitis in an asymptomatic woman on intrauterine contraceptive device. This case highlights to clinicians the need to be aware of the possibility of this association and to carry out relevant investigations so as to identify and treat these patients appropriately. Therefore, there is a need to put in place adequate public health intervention strategy to prevent genital herpes in women of reproductive age group with a view to preventing the possibility of congenital herpes in subsequent pregnancy.

  16. The string tension from smeared Wilson loops at large N

    International Nuclear Information System (INIS)

    We present the results of a high statistics analysis of smeared Wilson loops in 4-dimensional SU(N) Yang–Mills theory for various values of N. The data is used to analyze the behavior of smeared Creutz ratios, extracting from them the value of the string tension and other asymptotic parameters. A scaling analysis allows us to extrapolate to the continuum limit for N=3,5,6 and 8. The results are consistent with a 1/N2 approach towards the large N limit. The same analysis is done for the TEK model (one-point lattice) for N=841 and a non-minimal symmetric twist with flux of k=9. The results match perfectly with the extrapolated large N values, confirming the validity of the reduction idea for this range of parameters.

The data is used to analyze the behaviour of smeared Creutz ratios, extracting from them the value of the string tension and other asymptotic parameters. A scaling analysis allows us to extrapolate to the continuum limit for N=3,5,6 and 8. The results are consistent with a $1/N^2$ approach towards the large N limit. The same analysis is done for the TEK model (one-point lattice) for N=841 and a non-minimal symmetric twist with flux of $k=9$. The results match perfectly with the extrapolated large N values, confirming the validity of the reduction idea for this range of parameters.

  18. Delay in treatment seeking of smear positive tuberculous patients

    International Nuclear Information System (INIS)

    To assess and identify the causes and circumstances leading to delays in health seeking and diagnosis of tuberculosis patients as they often present with advance disease resulting in increased morbidity and mortality. Settings Department of Tuberculosis, DOTS clinic DHQ Hospital, Vehari. Methodology One (author) inspiration diagnosed smear positive pulmonary tuberculosis patients were included. Information was gathered through interviews and from TB-01 card. Results Maximum patients were in age group of 16-40 years. Median patient delay was 4-6 months; jobless, homeless personnel had longer delay. The main reason for delay was that the symptoms were not considered serious enough. Delay in presentation of smear positive cases may be due to the lack of awareness of patients and the incompetence of some health workers. Training and supervision of staff and awareness campaigns targeted at the population and involvement of private sector will improve TB control in Vehari. (author)

    Full Text Available Objective: To describe and interpret women’s perceptions about cervical cancer, its causes, prevention and self care. Methodology: qualitative studie, through the discussion group, 22 groups were formed in three municipalities in Antioquia (Colombia and one municipality of Colima (Mexico, with 108 women. Results: descriptions and interpretations are collectively influenced by information from the health sector, the media and the family. Most women are not related cervical cancer or cervical infections with sexual and reproductive behavior. The acceptance of the Pap smear is a product of experience and responsibility. Conclusions: equity in access considers cultural differences and specific needs of women, breaking cultural barriers and opens up opportunities for participation in health services. In body care, women recognize the level of severity of signs and gynecoobstetrical symptoms and the need for medical care. There is little knowledge about cervical cancer, its causes and prevention, due to lack of information and education from health care providers.

    Full Text Available The purpose of this case report is to point out the diagnostic value of cytologic smears in patients presenting with anorectal complaints, such as bleeding, pain or discomfort, which may suggest a neoplastic lesion. We present a case of a 64-year-old man with a 3 months′ history of anal bleeding and pain during defecation. He was diagnosed as having hemorrhoids and a hemorrhoidectomy was performed. The patient developed an anal stricture postoperatively that required operative dilation. He continued to complain about anorectal pain for 2 months and a subsequent rectoscopy revealed the presence of tumor 5 to 7 cm above the dentate line. The tumor was resected laparoscopically and was reported as an adenocarcinoma. Rectal bleeding recurred 18 months postoperatively and a smear was procured from the anorectal mucosal surface for cytologic evaluation. A definitive diagnosis of adenocarcinoma was rendered based on cytologic and histologic examination of the material. To the best of our knowledge, this is the first case report of anorectal adenocarcinoma diagnosed by cytologic smear in the English literature.

    Full Text Available Abstract Human Papillomavirus (HPV is the most common cause of cervical cancer. Cervical cancer being the second most common cancer after lung cancer, affecting women of different age groups; has a prevalence of about 20% in young sexually active women. Among different types of HPV, HPV16 the major strain causing this cancer and is sexually transmitted had been unnoticed for decades. Keeping in mind the multiple risk factors related with cervical cancer such as early age sexual activities, teenage pregnancies, smoking, use of oral contraceptives, having multiple sex partners, hormone replacement therapies and various other unknown factors lead to the onset of the disease. Awareness for various diagnostic procedures such as Pap smears screening prove to be an effective way in eradicating the oncogenic potential of HPV.

    Full Text Available OBJECTIVE: The purpose of this study was to evaluate by scanning electron microscopy (SEM the removal of smear layer from the middle and apical root thirds after use of different irrigating solutions. MATERIAL AND METHODS: Forty roots of permanent human teeth had their canals instrumented and were randomly assigned to 4 groups (n=10, according to the irrigating solution: apple vinegar (group A, apple vinegar finished with 17% ethylenediaminetetraacetic acid (EDTA (group B, 1% sodium hypochlorite (NaOCl finished with 17% EDTA (group C and saline (group D - control. After chemomechanical preparation, the roots were cleaved longitudinally and their middle and apical thirds were examined by SEM at ×1,000 magnification. Two calibrated examiners (kappa=0.92 analyzed the SEM micrographs qualitatively attributing scores that indicated the efficacy of the solutions in removing the smear layer from the surface of the dentin tubules (1 - poor, 2 - good and 3 - excellent. Data from the control and experimental groups were analyzed by the Kruskal-Wallis and Dunn's test, while the Wilcoxon test was used to compare the middle and apical thirds of the canals within the same group (a=0.05. RESULTS: The middle third presented less amount of smear layer than the apical third, regardless of the irrigant. There was statistically significant difference (p=0.0402 among the groups in the middle third. In the apical third, the apple vinegar/EDTA group showed the greatest removal of smear layer (p=0.0373. CONCLUSION: Apple vinegar associated or not with EDTA was effective in removing smear layer when used as an endodontic irrigant.

    Grief over the loss of a family member may cause physical and mental illness, but an association between bereavement and cancer risk has not been established. Based on the Swedish National Cervical Screening Register (1969-2011) including 14,011,269 smears from 2,466,107 women, we conducted two nested case-control studies to examine the associations of bereavement (i.e., loss of a family member due to death) with abnormal cytology (390,310 first abnormal and 1,951,319 normal smears) and in situ/invasive cervical cancer (75,128 case and 375,640 control women), both individually matched on year of birth and screening adherence. Among 1,696 of the control women, we further investigated bereavement in association with human papillomavirus (HPV) infection, both HPV16 and other HPV types. Bereavement was consistently associated with a 4% to 9% increased risk for first abnormal cytology, in situ and invasive cervical cancer (all P viral load, and recurrent infection, and was also more strongly associated with HPV infections designated as high-risk compared with low-risk determinants of cervical carcinogenesis. Collectively, our findings demonstrate that bereavement is associated with an increased risk of developing cervical cancer. Further, they suggest that this association may be attributed to stress-induced oncogenic HPV infections. PMID:26634926

    OBJECTIVE: The aim of this study was to determine the prevalence of cervical Chlamydia trachomatis infection by polymerase chain reaction (PCR) in urban women undergoing routine cervical cytological screening and to investigate the relationship with age, cytology, smoking status and concurrent human papillomavirus (HPV) infection. METHODS: A total of 996 women (age range 16-69 years) attending general practitioners for routine liquid-based cervical smear screening in the Dublin area were recruited in the study of prevalence of C. trachomatis. Informed consent was obtained and liquid-based cytology (LBC) specimens were sent for cytological screening. DNA was extracted from residual LBC and tested for C. trachomatis by PCR using the highly sensitive C. trachomatis plasmid (CTP) primers and for HPV infection using the MY09\\/11 primers directed to the HPV L1 gene in a multiplex format. RESULTS: The overall prevalence of C. trachomatis was 5.4%. Prevalence was highest in the <25 years age group (10%). Coinfection with HPV and C. trachomatis occurred in 1% of the screening population. A higher rate of smoking was observed in women positive for C. trachomatis, HPV infections or those with abnormal cervical cytology. Chlamydia trachomatis infection was not associated with abnormal cytology. CONCLUSIONS: Women (5.4%) presenting for routine cervical screening are infected with C. trachomatis. Opportunistic screening for C. trachomatis from PreservCyt sample taken at the time of cervical cytological screening may be a possible strategy to screen for C. trachomatis in the Irish female population.

    Cervical cancer incidence rates have decreased dramatically since the implementation of the Papanicolaou (Pap) smear. Nevertheless, the American Cancer Society (ACS) estimates for 2013 predicted more than 12,000 new cases of cervical cancer in the United States. Given that some subpopulations in the United States are at a higher risk for cervical cancer than others, efforts to increase screening adherence are warranted. Many studies have explored the demographics of underscreened women, but no systematic reviews of screening demographics in adult US women were identified in the past 10 years, after release of the 2002 ACS cervical cancer screening guidelines. Knowledge of adherence to these guidelines becomes important as new guidelines were developed and released in 2012. The purpose of this systematic review of relevant studies was to identify factors that predict the use of cervical cancer screening in US women. Variables found to be significantly associated with adherence to screening included education, financial status, acculturation, psychosocial issues, and marital status. Using this information, nurse practitioners and other providers can target specific at-risk populations to increase screening by educating women about the need for cervical cancer screening and ensuring access to methods for prevention and early detection of the disease.

    Full Text Available Tuberculosis (TB is a disease of public health concern, with a varying distribution across settings depending on socio-economic status, HIV burden, availability and performance of the health system. Ethiopia is a country with a high burden of TB, with regional variations in TB case notification rates (CNRs. However, TB program reports are often compiled and reported at higher administrative units that do not show the burden at lower units, so there is limited information about the spatial distribution of the disease. We therefore aim to assess the spatial distribution and presence of the spatio-temporal clustering of the disease in different geographic settings over 10 years in the Sidama Zone in southern Ethiopia.A retrospective space-time and spatial analysis were carried out at the kebele level (the lowest administrative unit within a district to identify spatial and space-time clusters of smear-positive pulmonary TB (PTB. Scan statistics, Global Moran's I, and Getis and Ordi (Gi* statistics were all used to help analyze the spatial distribution and clusters of the disease across settings.A total of 22,545 smear-positive PTB cases notified over 10 years were used for spatial analysis. In a purely spatial analysis, we identified the most likely cluster of smear-positive PTB in 192 kebeles in eight districts (RR= 2, p<0.001, with 12,155 observed and 8,668 expected cases. The Gi* statistic also identified the clusters in the same areas, and the spatial clusters showed stability in most areas in each year during the study period. The space-time analysis also detected the most likely cluster in 193 kebeles in the same eight districts (RR= 1.92, p<0.001, with 7,584 observed and 4,738 expected cases in 2003-2012.The study found variations in CNRs and significant spatio-temporal clusters of smear-positive PTB in the Sidama Zone. The findings can be used to guide TB control programs to devise effective TB control strategies for the geographic areas

    An experiment was performed in the Experimental Breeder Rector-II (EBR-II) in the 1990s to show that metallic fast reactor fuel could be used in reactors with a single, once-through core. To prove the long duration, high burnup, high neutron exposure capability an experiment where the fuel pin was designed with a very large fission gas plenum and very low fuel smeared density (SD). The experiment, X496, operated to only 8.3 at.% burnup because the EBR-II reactor was scheduled for shut-down at that time. Many of the examinations of the fuel pins only funded recently with the resurgence of reactor designs using very high-burnup fuel. The results showed that, despite the low smeared density of 59% the fuel swelled radially to contact the cladding, fission gas release appeared to be slightly higher than demonstrated in conventional 75%SD fuel tests and axial growth was about the same as 75% SD fuel. There were axial positions in some of the fuel pins which showed evidence of fuel restructuring and an absence of fission products with low melting points and gaseous precursors (Cs and Rb). A model to investigate whether these areas may have overheated due to a loss of bond sodium indicates that it is a possible explanation for the fuel restructuring and something to be considered for fuel performance modeling of low SD fuel.

  20. Development of an automatic smear sampler and a polymer film for surface radioactive contamination assay

    International Nuclear Information System (INIS)

    Measurement of the surface contamination by an indirect method is subject to the various kinds of error according to the sampling person and needs much time and effort in the sampling and assay. In this research, an automatic smear sampler is developed. It improved efficiency for assay work of surface contamination level achieved periodically in a radiation controlled area. Using an automatic smear sampler developed, it is confirmed that radioactive contaminated materials are uniformly transferred to smear paper more than any sampling method by an operator. Also, Solid scintillation proximity membranes were prepared for measuring the amount of radioactive contamination in laboratories contaminated by the low energy beta-ray emitter, such as 3H and 14C. Polysulfone scintillation proximity membranes were prepared by impregnating Cerium Activated Yttrium Silicate (CAYS), an inorganic fluor, in a membrane structure. The inorganic fluor-impregnated membranes were applied to detect the radioactive surface contamination. The preparation of membranes was divided into two processes. A supporting polymer film was made of casting solutions consisting of polysulfone and solvent, their cast film being solidified by vacuum evaporation. CAYS-dispersed polymer solutions were cast over the first, solidified polymer films and coagulated either by evaporating solvent in the solution with non-solvent in a coagulation bath. The prepared membranes had two distinguished, but tightly attached, double layers : one is the supporting layer of dense polymer film and the other results revealed that the prepared membranes were efficient to monitor radioactive contamination with reliable counting ability. For enhancement of pick-up and measurement efficiency, the membrane was prepared with the condition of different membrane solidification. The scintillation produced by interaction with radiation and CAYS was measured with photomultiplier tube. The test results showed that the prepared membranes

    Objective Invasive cervical cancer (ICC) is the fourth most common cancer among women worldwide. Cervical screening programs have reduced the incidence and mortality rates of ICC. We studied the cost-effectiveness of different cervical screening strategies in the Islamic Republic of Iran, a Muslim country with a low incidence rate of ICC. Methods We constructed an 11-state Markov model, in which the parameters included regression and progression probabilities, test characteristics, costs, and utilities; these were extracted from primary data and the literature. Our strategies included Pap smear screening and human papillomavirus (HPV) DNA testing plus Pap smear triaging with different starting ages and screening intervals. Model outcomes included lifetime costs, life years gained, quality-adjusted life years (QALY), and incremental cost-effectiveness ratios (ICERs). One-way sensitivity analysis was performed to examine the stability of the results. Results We found that the prevented mortalities for the 11 strategies compared with no screening varied from 26% to 64%. The most cost-effective strategy was HPV screening, starting at age 35 years and repeated every 10 years. The ICER of this strategy was $8,875 per QALY compared with no screening. We found that screening at 5-year intervals was also cost-effective based on GDP per capita in Iran. Conclusion We recommend organized cervical screening with HPV DNA testing for women in Iran, beginning at age 35 and repeated every 10 or 5 years. The results of this study could be generalized to other countries with low incidence rates of cervical cancer. PMID:27276093

  3. High prevalence of HPV in non-cervical sites of women with abnormal cervical cytology

    International Nuclear Information System (INIS)

    Human papillomaviruses (HPV) are causally associated with ano-genital and a subset of head and neck cancers. Rising incidence of HPV+ anal cancers and head and neck cancers have now been demonstrated in the developed world over the last decade. The majority of published data on HPV prevalence at the anal and oro-pharyngeal sites are from studies of higher-risk populations. There is a paucity of data on the prevalence of HPV at non-cervical sites in lower risk, non-HIV+ women and this study was designed to provide initial pilot data on a population of women recalled for colposcopy as part of the UK cervical screening programme. 100 non-HIV+ women with abnormal cervical cytology, attending clinic for colposcopic examination were recruited. Swabs from the oro-pharyngeal, anal and cervical sites were taken and DNA extracted. HPV detection and genotyping were performed using a standardised, commercially available PCR-line blot assay, which is used to genotype 37 HPV subtypes known to infect the ano-genital and oro-pharyngeal areas. Strict sampling and laboratory precautions were taken to prevent cross-contamination. There was a very high prevalence of HPV infection at all three sites: 96.0%, 91.4% and 92.4% at the cervix, anus and oro-pharynx, respectively. Multiple HPV subtype infections were dominant at all 3 mucosal sites. At least one or more HR genotype was present at both the cervix/anus in 39/52 (75.0%) patients; both the cervix/oro-pharynx in 48/56 (85.7%) patients; and both the anus/oro-pharynx in 39/52 (75.0%) patients. HPV 16 infection was highly dominant across all mucosal sites, with over a 2-fold increase over the next most prevalent subtype (HPV 31). Women with abnormal smears have widespread infection with high-risk HPV at the cervical, anal and oro-pharyngeal mucosal sites and may represent a higher risk population for HPV disease in the future

    Cervical cancer (CC) is caused by high-risk human papillomavirus persistence due to the immunosuppressive tumor microenvironment mediated by cytokines. Vaginal microbiota determines the presence of certain cytokines locally. We assessed the association between cervical microbiota diversity and the histopathological diagnosis of each stage of CC, and we evaluated mRNA cervical expression levels of IL-4, IL-6, IL-10, TGF-β1, TNF-α and IFN-γ across the histopathological diagnosis and specific bacterial clusters. We determined the cervical microbiota by high throughput sequencing of 16S rDNA amplicons and classified it in community state types (CST). Mean difference analyses between alpha-diversity and histopathological diagnosis were carried out, as well as a β-diversity analysis within the histological diagnosis. Cervical cytokine mRNA expression was analyzed across the CSTs and the histopathological diagnoses. We found a significant difference in microbiota's diversity in NCL-HPV negative women vs those with squamous intraepithelial lesions (SIL) and CC(p = 0.006, p = 0.036).When β-diversity was evaluated, the CC samples showed the highest variation within groups (p<0.0006) and the largest distance compared to NCL-HPV negative ones (p<0.00001). The predominant bacteria in women with normal cytology were L. crispatus and L. iners, whereas for SIL, it was Sneathia spp. and for CC, Fusobacterium spp. We found higher median cervical levels of IL-4 and TGF-β1 mRNA in the CST dominated by Fusobacterium spp. These results suggest that the cervical microbiota may be implicated in cervical cancer pathology. Further cohort studies are needed to validate these findings. PMID:27115350

    A discogenic cervical headache is a subtype of cervicogenic headache (CEH) that arises from a degenerative cervical disc abnormality. The purpose of this study was to evaluate the clinical outcome of percutaneous endoscopic cervical discectomy (PECD) for patients with chronic cervical headache due to soft cervical disc herniation. Seventeen patients underwent PECD for intractable headache. The inclusion criteria were soft disc herniation without segmental instability, proven by both local anesthesia and provocative discography for headache unresponsive to conservative treatment. The mean follow-up period was 37.6 months. Fifteen of the 17 patients (88.2%) showed successful outcomes based on the Macnab criteria. Pain scores on a visual analog scale (VAS) improved from a preoperative mean of 8.35{+-}0.79 to 2.12{+-}1.17, postoperatively (P<0.01). The mean disc height decreased from 6.81{+-}1.08 to 5.98{+-}1.07 mm (P<0.01). There was no newly developed segmental instability or spontaneous fusion on follow-up radiography. In conclusion, PECD appears to be effective for chronic severe discogenic cervical headache under strict inclusion criteria. (orig.)

    We have investigated the potential application of elastic light single-scattering spectroscopy (ELSSS) as an adjunctive tool for screening of cervical precancerous lesions non-invasively and in real time. Ex-vivo measurements were performed on 95 cervix biopsy tissue of 60 patients. Normal cervix tissue from 10 patients after hysterectomy was used as a control group. Correlation between ELSSS spectra and histopathology results were investigated. It was found that the spectral slope was positive for all the spectra taken on normal cervix tissue samples from the control group. We assumed that if there is only one spectrum with a negative spectral slope among the all spectra taken on a biopsy specimen, the biopsy specimen is pathologically abnormal. This shows that pap smear and ELSSS results are in good agreement. Most biopsy tissue samples had both positive and negative spectral slopes. Therefore, we calculated the percentage of negative spectral slopes and hypothesized that this was correlated to dysplastic percentage of the epithelial tissue of the biopsy material. The ROC curve was calculated using the dysplastic percentage and high squamous intraepithelial lesion (HSIL) and low squamous intraepitherlial lesions (LSIL) biopsy specimens were differentiated from non HSIL and LSIL with a sensitivity and specificity of 70.4% and 66.7% respectively, with p < 0.05.

    Full Text Available MicroRNAs' dysregulation and profiling have been demonstrated to be clinically relevant in urothelial carcinoma (UC. Urine cytology is commonly used as the mainstay non-invasive test for secondary prevention and follow-up of UC patients. Ancillary tools are needed to support cytopathologists in the diagnosis of low-grade UC. The feasibility and reliability of microRNAs profiling by qRT-PCR analysis (miR-145 and miR-205 in archival routine urine cytology smears (affected by fixation/staining [Papanicolau] and room temperature storage was tested in a series of 15 non-neoplastic and 10 UC urine specimens. Only samples with >5,000 urothelial cells and with <50% of inflammatory cells/red blood cells clusters were considered. Overall, a satisfactory amount of total RNA was obtained from all the considered samples (mean 1.27±1.43 µg, range 0.06-4.60 µg. Twenty nanograms of total RNA have been calculated to be the minimal total RNA concentration for reliable and reproducible miRNAs expression profiling analysis of archival cytological smears (slope= -3.4084; R-squared=0.99; efficiency=1.94. miR-145 and miR-205 were significantly downregulated in UC samples in comparison to non-tumor controls. These findings demonstrate that urine archival cytology smears are suitable for obtaining high-quality RNA to be used in microRNAs expression profiling. Further studies should investigate if miRNAs profiling can be successfully translated into clinical practice as diagnostic or prognostic markers.

    Full Text Available Peripheral blood smear image examination is a part of the routine work of every laboratory. The manual examination of these images is tedious, time-consuming and suffers from interobserver variation. This has motivated researchers to develop different algorithms and methods to automate peripheral blood smear image analysis. Image analysis itself consists of a sequence of steps consisting of image segmentation, features extraction and selection and pattern classification. The image segmentation step addresses the problem of extraction of the object or region of interest from the complicated peripheral blood smear image. Support vector machine (SVM and artificial neural networks (ANNs are two common approaches to image segmentation. Features extraction and selection aims to derive descriptive characteristics of the extracted object, which are similar within the same object class and different between different objects. This will facilitate the last step of the image analysis process: pattern classification. The goal of pattern classification is to assign a class to the selected features from a group of known classes. There are two types of classifier learning algorithms: supervised and unsupervised. Supervised learning algorithms predict the class of the object under test using training data of known classes. The training data have a predefined label for every class and the learning algorithm can utilize this data to predict the class of a test object. Unsupervised learning algorithms use unlabeled training data and divide them into groups using similarity measurements. Unsupervised learning algorithms predict the group to which a new test object belong to, based on the training data without giving an explicit class to that object. ANN, SVM, decision tree and K-nearest neighbor are possible approaches to classification algorithms. Increased discrimination may be obtained by combining several classifiers together.

    International Nuclear Information System (INIS)

    To determine the diagnostic accuracy of slit skin smears in clinically suspected patients of leprosy using histopathology as gold standard. Study Design: Validation study Place and Duration of Study: Study was carried out at Rawalpindi Leprosy Hospital, Dermatology Department Military Hospital (MH) and Armed Forces Institute of Pathology (AFIP), Rawalpindi from 18th August 2012 to 18 Feb 2013. Methods: Appropriate technical and ethical approval for the study and patient consent were obtained. All suspected patients of leprosy of any age and either gender having typical hypo-aesthetic or anesthetic, erythematous or hypo-pigmented scaly skin lesions on any part of body were included in this study. All patients who have already received treatment for leprosy, patients with pure neural leprosy, patient not giving their consent for skin biopsy and patients with lepra reactions were excluded from this study. Forty eight patients fulfilling the inclusion criteria were included in the study. Sample size had been calculated by using WHO sample size calculator taking confidence level 95%, absolute precision required 14% and anticipated population proportion 40%. Non-probability consecutive sampling technique was used to collect sample. Results: The results of the study revealed that out of 48 clinically suspected patients of leprosy skin biopsy confirmed the diagnosis in 34 patients (70.8%) and the slit skin smear had diagnostic accuracy of 68.75% with sensitivity 55.8% and specificity and positive predictive value of 100%. Conclusion: Study suggested that although slit skin smears are rapid and inexpensive method of diagnosis but their diagnostic accuracy is low. (author)

    Full Text Available As a contribution to the public health authorities in planning prophylactic and therapeutic vaccine strategies, we describe the prevalence of human papillomavirus (HPV types in women presenting abnormal cytological results in Pap smear screening tests in the Federal District, Central Brazil. We studied 129 cervical scraping samples from women whose cytological tests showed either pre-neoplastic or neoplastic lesions. Amplification of HPV DNA was performed by polymerase chain reaction using consensus primers MY09 and MY11 followed by identification of isolates by restriction fragment length polymorphism. We detected HPV DNA in 62% of the samples, including HPV-16 in 43.8%, HPV-58 in 12.5%, HPV-31 in 10%, HPV-53 in 6.3%, each of HPV-18 and HPV-33 in 3.8% of the isolates. Other types (HPV-35, -52, -66, -CP8304, -6, -11, and -CP8061 were less frequent (= or < 2.5% each. The prevalence of HPV-58 was relatively higher in this population than in data in South America, but similar to results obtained in other studies in Latin America, Europe, and Eastern Asia. Case-control studies need to be carried out to establish the association between the prevalence of HPV types specially the less frequent high-risk types and cervical cancer.

    Cervical Intraepithelial Neoplasia (CIN) is a precursor to invasive cervical cancer, which annually accounts for about 3700 deaths in the United States and about 274,000 worldwide. Early detection of CIN is important to reduce the fatalities due to cervical cancer. While the Pap smear is the most common screening procedure for CIN, it has been proven to have a low sensitivity, requiring multiple tests to confirm an abnormality and making its implementation impractical in resource-poor regions. Colposcopy and cervicography are two diagnostic procedures available to trained physicians for non-invasive detection of CIN. However, many regions suffer from lack of skilled personnel who can precisely diagnose the bio-markers due to CIN. Automatic detection of CIN deals with the precise, objective and non-invasive identification and isolation of these bio-markers, such as the Acetowhite (AW) region, mosaicism and punctations, due to CIN. In this paper, we study and compare three different approaches, based on Mathematical Morphology (MM), Deterministic Annealing (DA) and Gaussian Mixture Models (GMM), respectively, to segment the AW region of the cervix. The techniques are compared with respect to their complexity and execution times. The paper also presents an adaptive approach to detect and remove Specular Reflections (SR). Finally, algorithms based on MM and matched filtering are presented for the precise segmentation of mosaicism and punctations from AW regions containing the respective abnormalities.

    Full Text Available Abstract Cervical cancer remains one of the greatest killers of women worldwide. It is difficult to foresee a dramatic increase in cure rate even with the most optimal combination of cytotoxic drugs, surgery, and radiation; therefore, testing of molecular targeted therapies against this malignancy is highly desirable. A number of epigenetic alterations occur during all stages of cervical carcinogenesis in both human papillomavirus and host cellular genomes, which include global DNA hypomethylation, hypermetylation of key tumor suppressor genes, and histone modifications. The reversible nature of epigenetic changes constitutes a target for transcriptional therapies, namely DNA methylation and histone deacetylase inhibitors. To date, studies in patients with cervical cancer have demonstrated the feasibility of reactivating the expression of hypermethylated and silenced tumor suppressor genes as well as the hyperacetylating and inhibitory effect upon histone deacetylase activity in tumor tissues after treatment with demethylating and histone deacetylase inhibitors. In addition, detection of epigenetic changes in cytological smears, serum DNA, and peripheral blood are of potential interest for development of novel biomolecular markers for early detection, prediction of response, and prognosis.

    Of the many types of human papillomavirus (HPV), more than 30 infect the genital tract. The association between certain oncogenic (high-risk) strains of HPV and cervical cancer is well established. Although HPV is essential to the transformation of cervical epithelial cells, it is not sufficient, and a variety of cofactors and molecular events influence whether cervical cancer will develop. Early detection and treatment of precancerous lesions can prevent progression to cervical cancer. Ident...

  19. Endometrial cancer with cervical extension mimicking dual concordant endometrial and cervical malignancy by F18 FDG PET and MRI

    International Nuclear Information System (INIS)

    A 35 year old woman with endometrial cancer and cervical extension underwent F18 FDG PET CT and MRI studies after resection of a cervical mass presumed to be cervical myoma. The patient underwent cervical myomectomy and the histopathologic report revealed poorly differentiated invasive carcinoma. Cervical cancer was ruled out because the patient had no history of sexual intercourse and was negative for human papilloma virus infection. The patient underwent radical hysterectomy, bilateral salpingo oophorectomy, pelvic and para aortic lymph node dissection, and multiple biopsies. F18 FDG PET CT showed intense FDG uptake along the cervix wall. T2 weighted MRI also revealed a mass lesion with high SI involving the anterior and posterior lips of the uterine cervix. Another area of focal increased uptake above the endometrial lesion in the left pelvic cavity was observed on PET CT and MRI, possibly due to a functioning ovary. PET CT and MRI were interpreted as showing a dual concordant malignant lesion due to separated FDG uptakes and high SI without any connection between the cervical and endometrial lesions. F18 FDG PET CT showed intense FDG uptake along the endometrium. Given the patient's history and the fact that she was not menstruating at the time of imaging, this intense uptake was interpreted as another pathologic lesion, suggesting dual primary lesions. A suspected heterogeneous mass lesion along the endometrium suggesting concordant endometrial cancer was found on MRI. Endometrial cancer with cervical extension is sometimes difficult to differentiate from primary cervical cancer. The final histopathologic report showed poorly differentiated endometrial adenocarcinoma with cervical extension, although the FDG PET CT and MRI findings were suggestive of concordant cervical and endometrial cancer. Although histopathologic confirmation is necessary for final diagnosis, MRI and FDG PET CT studies may aid in the differential diagnosis. A metastatic cervical mass from

    Jing Rui Tang

    Full Text Available Despite the effectiveness of Pap-smear test in reducing the mortality rate due to cervical cancer, the criteria of the reporting standard of the Pap-smear test are mostly qualitative in nature. This study addresses the issue on how to define the criteria in a more quantitative and definite term. A negative Pap-smear test result, i.e. negative for intraepithelial lesion or malignancy (NILM, is qualitatively defined to have evenly distributed, finely granular chromatin in the nuclei of cervical squamous cells. To quantify this chromatin pattern, this study employed Fuzzy C-Means clustering as the segmentation technique, enabling different degrees of chromatin segmentation to be performed on sample images of non-neoplastic squamous cells. From the simulation results, a model representing the chromatin distribution of non-neoplastic cervical squamous cell is constructed with the following quantitative characteristics: at the best representative sensitivity level 4 based on statistical analysis and human experts' feedbacks, a nucleus of non-neoplastic squamous cell has an average of 67 chromatins with a total area of 10.827 μm2; the average distance between the nearest chromatin pair is 0.508 μm and the average eccentricity of the chromatin is 0.47.

    Full Text Available Background: Cervical cancer is the commonest malignancy among women in developing countries. Cytological screening (Pap smear have been claimed to reduce incidence and mortality of carcinoma cervix significantly for which sensitization of women is required through community-based approach. Objectives: To find out number of cervical cancer cases among patients reporting to a general health care camp through screening program and study the prevalence of perceived morbidity and its confirmation. Settings: Cross-sectional study among women attending cancer awareness camps. Materials and Methods: A total of 435 women attending cancer awareness camps were screened for carcinoma cervix. The findings of history and clinical examination were recorded. Pap smears of all the symptomatic patients were collected and cytological diagnosis was confirmed by a pathologist. Results and Conclusions: The perceived gynecological morbidity was observed to be 59.8%. The smear of the women who were suspected of carcinoma on clinical examination was confirmed to be the cases of carcinoma-in-situ (7.8% and high-grade neoplasia (2.9% on laboratory investigations. The findings of the study highlight the utility and need of cancer cervix screening among the women at regular intervals through camp approach in the community.

    Full Text Available The aim of this study was to evaluate the association between the frequency of micronuclei (MN and the cellular changes detected in the conventional Papanicolaou test. One hundred and seventy-four Papanicolaou test smears with cellular changes were examined. MN screening was done in cytopathological smears by counting 1,000 cervical cells in a light microscope. MN frequencies were significantly higher in the group with cellular changes compared to the control group (p < 0.001. The mean MN frequencies were 0.95 ± 1.12 (mean ± SD in the control group (n = 223, 2.98 ± 1.20 in individuals with atypical squamous cells of undetermined significance (ASC-US (n = 50, 4.04 ± 1.45 in cervical intraepithelial neoplasia (CIN I (n = 52, 5.97 ± 1.83 in CIN II (n = 30, 7.29 ± 1.55 in CIN III (n = 17 and 8.64 ± 1.55 in invasive cancer (n = 25. These findings suggest that MN monitoring should be included as an additional criterion for the early detection of cytogenetic damage in routine examinations. This monitoring should be done in the same smear as used for cytopathological examination. More specific and systematic studies are necessary to confirm this proposal.

    BACKGROUND: As carriers of filaggrin gene (FLG) mutations may have a compromised cervical mucosal barrier against human papillomavirus infection, our primary objective was to study their risk of cervical cancer. METHODS: We genotyped 586 cervical cancer patients for the two most common FLG...... mutations, R501X and 2282del4, using blood from the Copenhagen Hospital Biobank, Denmark. Controls (n = 8050) were genotyped in previous population-based studies. Information on cervical cancer, mortality and emigration were obtained from national registers. Odds ratios (OR) were estimated by logistic...... and stratification by cancer stage. RESULTS: The primary results showed that FLG mutations were not associated with the risk of cervical cancer (6.3% of cases and 7.7% of controls were carriers; OR adjusted 0.81, 95% CI 0.57-1.14; OR adjusted+ weighted 0.96, 95% CI 0.58-1.57).

    Imaging techniques provide excellent anatomical images of the cervical spine. The choice to use one technique or another will depend on the clinical scenario and on the treatment options. Plain-film X-rays continue to be fundamental, because they make it possible to evaluate the alignment and bone changes; they are also useful for follow-up after treatment. The better contrast resolution provided by magnetic resonance imaging makes it possible to evaluate the soft tissues, including the intervertebral discs, ligaments, bone marrow, and spinal cord. The role of computed tomography in the study of degenerative disease has changed in recent years owing to its great spatial resolution and its capacity to depict osseous components. In this article, we will review the anatomy and biomechanical characteristics of the cervical spine, and then we provide a more detailed discussion of the degenerative diseases that can affect the cervical spine and their clinical management.

    High-precision time series photometry with the Kepler satellite has been crucial to our understanding both of exoplanets, and via asteroseismology, of stellar physics. After the failure of two reaction wheels, the Kepler satellite has been repurposed as Kepler-2 (K2), observing fields close to the ecliptic plane. As these fields contain many more bright stars than the original Kepler field, K2 provides an unprecedented opportunity to study nearby objects amenable to detailed follow-up with ground-based instruments. Due to bandwidth constraints, only a small fraction of pixels can be downloaded, with the result that most bright stars which saturate the detector are not observed. We show that engineering data acquired for photometric calibration, consisting of collateral `smear' measurements, can be used to reconstruct light curves for bright targets not otherwise observable with Kepler/K2. Here we present some examples from Kepler Quarter 6 and K2 Campaign 3, including the δ Scuti variables HD 178875 and 70 Aqr, and the red giant HR 8500 displaying solar-like oscillations. We compare aperture and smear photometry where possible, and also study targets not previously observed. These encouraging results suggest this new method can be applied to most Kepler and K2 fields.

    Full Text Available Filariasis is a major health problem in tropical countries like India. Detection of egg with or without larva in fine-needle aspiration cytology (FNAC is very unusual despite the high incidence of this parasite in endemic zone. Early diagnosis and treatment prevent the more severe manifestations of disease. A 6-year-old male from eastern Uttar Pradesh presented with the complaints of axillary swelling, fever and loss of appetite. On examination, swelling was 3 cm × 2 cm in size, freely mobile, firm and non-tender. FNA was performed and air-dried smears were stained with Giemsa stain. Smears showed many short and blunt larvae without any distinct sheath and nuclei. Numerous round to oval eggs with short coiled larvae inside them were also seen. A diagnosis of filarial lymphadenopathy was made. The case was considered worth documentation to highlight the finding of filarial eggs in FNA of lymph node, which can be missed or misdiagnosed by an unexperienced pathologist leading to delayed or wrong treatment of a curable disease.

    Full Text Available Background: Cervical cancer is the most common cancer among females in India. It is also one of the major causes of deaths among them. Papanicolaou (Pap cytological test helps in detecting the early epithelial abnormalities in cervical cells. The morbidity and mortality due to cervical cancer has come down in countries with well-established screening programmes at national level. This study was conducted to emphasize the value of cervical screening as a tool for early detection of non-neoplastic and neoplastic lesions of cervix. Slide positivity rate was computed and clinico-pathological correlation was done. Methods: This cross-sectional study was conducted from January 2012 to December 2014 (3 years, on 2202 women aged between 20-70 years coming for a Pap smear examination in a tertiary care hospital in Bareilly, India. After staining with conventional Papanicolaou technique, all cases were classified as per Bethesda nomenclature (2001. Results: Out of 2202 cases, 85.16% slides were found to be negative for intraepithelial abnormalities and 14.84% slides were labelled as positive for epithelial lesions. 97.67% of high grade lesions were found in women more than 40 years. Smears with epithelial cell abnormality were found more common in older age groups whereas smears negative for epithelial cell abnormality were found more common in young age groups. Conclusion: Pap test is a cost effective cancer screening and is a simple method to detect various lesions of cervix, non-neoplastic as well as neoplastic. High risk screening programmes should be directed to all women >40 years. Pap test is especially useful to diagnose precancerous lesions of cervix, thereby early detection of these lesions and subsequent proper treatment can be helpful in prevention of cervical cancer.

    The objective of this preliminary study was to evaluate the usefulness of the intradermal smear test in the diagnosis of malaria. One hundred cases of suspected malaria (having received no prior antimalarials) were investigated. Both peripheral blood film (PBF) and intradermal smears (IDS) were simultaneously prepared and patients placed on antimalarial therapy. The slides were repeated for the next 2 days. At admission, 70 cases were positive on PBF--59 were Plasmodium falciparum (PF) and 11 were Plasmodium vivax (PV) whereas surprisingly 62 cases were positive on IDS at admission--61 were PF, one was PV. IDS identified two more cases of PF [P value (not significant)] but failed to identify any new cases of PV (P value NS). On subsequent days IDS positivity for PF was higher than for PBF (P diagnostic tool in cases where malaria is strongly suspected but peripheral blood slides are repeatedly negative due to prior use of antimalarial therapy. IDS may be added to routine PBF in malaria (especially PF). PMID:12680550

    Full Text Available In last time Babesiosis as a tick-borne hemoprotozoans human disease have a very important role in differentil diagnostics of modern infectious medicine. It caused by protozon of the genus Babesia, which invade and destory erythrocytes. Babesiosis olso has been called tick fever. So, Babesia has been known by other genus names, including Nuttallia, Microbabesia, Babesialla, and Gonderia. Because all Babesia species are piroplasms, a more inclusive term for anthropozoonotic infections caused by these organisms would be piroplasmosis.They detective complicacy are bild that, tick-borne disease agents from prolongate life cycles involving arthropod and vertebrate host. The complexity is enhanced by the diversity of hosts in different biotopes, which depends on factors life type of vegetation, climate and/or human influence, such as restoration of former industrial sites, which leads to the development of new biotopes. So, on the one hand, new habitats for plants and animals including ticks, and nature are created. About the first case of babesiosis infection was reported as a cause of human sickness in 1969 in northeastern United State. Several hundred cases are now reported from this region each year. The disease is characterized by a grandual oncet of malaise with anorexia, fever, headaches, myalgia, and other vague symptoms, which may persist for long period. Occasionally dangerous fulminating infections occur particularly in immunocompromised or aged individuals. The purpose of the present research was to study of the cytological diagnostic of blood smears from object’s with the Babesia infection. Materials and methods. Blood smears (by Romanovsky- Gimze (standart, Wright’s standart and staining, the author’s modification, 2014 of domestic dogs (n = 31 of both sexes with Babesia infection at the age from 3 months to 6 years served as the material for the study.

    International Nuclear Information System (INIS)

    Rheumatoid cervical myelopathy was studied in 14 patients, clinically, radiographically and by computerized tomography with multiplanar reconstruction (CT/MPR). CT/MPR demonstrated significant unsuspected areas of compromise in 9 of the 14 patients, and altered the surgical procedure in 7 of these 9 patients. CT/MPR clearly identifies all levels of involvement including rotary subluxation. CT/MPR also allows assessment of the spinal nerve canal/foramen and the alignment of the foramina transversaria. CT/MPR is an essential addition to the evaluation of rheumatoid cervical myelopathy

    Full Text Available Cervical necrotizing fasciitis is an unusual encounter in the general surgical practice, but is a life-threatening condition requiring early recognition and adequate surgical treatment. We present the case of a 65 year old male patient referred to our department from a General Hospital. Large excisions of both superficial and deep cervical fascia were required together with necrotic skin on a very large surface. Rapid recovery with early sterilization allowed adequate skin grafting with good results. We advocate for aggressive debridment with excision in viable healthy tissue, with no concern for the future reconstruction followe by early grafting of the skin defect.

    Interphase fluorescence in situ hybridization (FISH) technology is a potential and promising molecular imaging tool, which can be applied to screen and detect cervical cancer. However, manual FISH detection method is a subjective, tedious, and time-consuming process that results in a large inter-reader variability and possible detection error (in particular for heterogeneous cases). Automatic FISH image analysis aims to potentially improve detection efficiency and also produce more accurate and consistent results. In this preliminary study, a new computerized scheme is developed to automatically segment analyzable interaphase cells and detect FISH signals using digital fluorescence microscopic images acquired from Pap-smear specimens. First, due to the large intensity variations of the acquired interphase cells and overlapping cells, an iterative (multiple) threshold method and a feature-based classifier are applied to detect and segment all potentially analyzable interphase nuclei depicted on a single image frame. Second, a region labeling algorithm followed up a knowledge-based classifier is implemented to identify splitting and diffused FISH signals. Finally, each detected analyzable cell is classified as normal or abnormal based on the automatically counted number of FISH signals. To test the performance of this scheme, an image dataset involving 250 Pap-smear FISH image frames was collected and used in this study. The overall accuracy rate for segmenting analyzable interphase nuclei is 86.6% (360/424). The sensitivity and specificity for classifying abnormal and normal cells are 88.5% and 86.6%, respectively. The overall cell classification agreement rate between our scheme and a cytogeneticist is 86.6%. The testing results demonstrate the feasibility of applying this automated scheme in FISH image analysis.

    Head and neck liposarcomas, while rare, tend to be subcutaneous and well-differentiated. Dedifferentiated liposarcomas of the head and neck are exceedingly rare in the literature. We present a case of a dedifferentiated liposarcoma arising in the soft tissue of the posterior neck of an 86-year-old man and diagnosed by fine-needle aspiration. Aspirate smears showed a dual population of atypical lipomatous and spindled cells. MDM2 (murine double minute 2) amplification was demonstrated on a Pap-stained smear using fluorescence in situ hybridization (FISH). To the best of our knowledge, this is the first report of MDM2 FISH amplification in a liposarcoma performed on an aspirate smear. PMID:25132684

    Smear microscopy is a rapid method for the identification of the most infectious patients with mycobacterial infection. Suboptimal smear microscopy may significantly compromise or delay patient isolation and contact tracing. A stringent method for auditing mycobacterial smear results is thus needed. This article proposes an auditing tool based on time to detection (TTD) of culture-positive samples using the automated BACTEC™ MGIT™ 960 TB system. In our study, sputum samples subjected to liquefaction and concentration before staining with a TTD of ≤ 13 days using the BACTEC system should be positive on smear microscopy. PMID:26260828

    Full Text Available Background: Cutaneous Leishmaniasis (CL is a parasitic skin disease. Diagnosis primarily is based on clinical signs and microscopic observation of parasite on direct stained smears or tissue sections. Sensitivity of direct smear is not as high as molecular methods. The aim of this study was to identify and characterize Leishmania species among the negative direct smears obtained from skin ulcers sus­pected to CL by PCR method.Methods: Among 81 patients with suspicious skin lesions to CL referred to the Parasitology lab, nega­tive Giemsa stained smears were collected. DNA extraction performed by scraping stained smears, then PCR was performed.Results: Among the DNA extracted from smears, L. tropica was isolated from 9 (11.1% of the smears and L.major was not isolated from any samples.Conclusion: Direct microscopy on stained smears for diagnosis of leishmaniasis is not enough accu­rate. PCR is recommended for clinically suspected lesions with negative result of direct smear.

    Proteins and antigens present on the cell surface are usually determined by immunofluorescence staining. Uniform distribution of cells is required to appreciate the presence of surface proteins. Improper smearing or crushing of the corneal epithelial cells can potentially destroy the cellular integrity. Thus a simplified, systemic method was designed to smear the cells scraped from the cornea. The procedure includes trypsinisation for dissociation of corneal epithelial cells and cytospinning for concentrating the cells in a smear. The standardized protocol was found to be efficient in maintaining the integrity of the corneal epithelial cells and also the distribution of the cells in the smear. PMID:26633702

    Cervical cancer is the main cancer among women in sub-Saharan Africa, India and other parts of the developing world. Evaluation of screening performance of effective, feasible and affordable early detection and management methods is a public health priority. Five screening methods, naked eye visual inspection of the cervix uteri after application of diluted acetic acid (VIA), or Lugol's iodine (VILI) or with a magnifying device (VIAM), the Pap smear and human papillomavirus testing with the high-risk probe of the Hybrid Capture-2 assay (HC2), were evaluated in 11 studies in India and Africa. More than 58,000 women, aged 25-64 years, were tested with 2-5 screening tests and outcome verification was done on all women independent of the screen test results. The outcome was presence or absence of cervical intraepithelial neoplasia (CIN) of different degrees or invasive cervical cancer. Verification was based on colposcopy and histological interpretation of colposcopy-directed biopsies. Negative colposcopy was accepted as a truly negative outcome. VIA showed a sensitivity of 79% (95% CI 73-85%) and 83% (95% CI 77-89%), and a specificity of 85% (95% CI 81-89%) and 84% (95% CI 80-88%) for the outcomes CIN2+ or CIN3+, respectively. VILI was on average 10% more sensitive and equally specific. VIAM showed similar results as VIA. The Pap smear showed lowest sensitivity, even at the lowest cutoff of atypical squamous cells of undetermined significance (57%; 95% CI 38-76%) for CIN2+ but the specificity was rather high (93%; 95% CI 89-97%). The HC2-assay showed a sensitivity for CIN2+ of 62% (95% CI 56-68%) and a specificity of 94% (95% CI 92-95%). Substantial interstudy variation was observed in the accuracy of the visual screening methods. Accuracy of visual methods and cytology increased over time, whereas performance of HC2 was constant. Results of visual tests and colposcopy were highly correlated. This study was the largest ever done that evaluates the cross

    Full Text Available Ethiopia adopted Public-Private Mix Directly Observed Treatment Short Course Chemotherapy (PPM-DOTS strategy for tuberculosis (TB control program. Quality of sputum smear microscopy has paramount importance for tuberculosis control program in resource-poor countries like Ethiopia. A cross-sectional study was conducted to assess the quality of sputum smear microscopy in 37 Public-Private Mix laboratories in West Amhara, Ethiopia. The three external quality assessment methods (onsite evaluation, panel testing and blind rechecking were employed. Onsite assessment revealed that 67.6% of PPM-DOTS laboratories were below the standard physical space (5 X 6 m2. The average monthly workload per laboratory technician was 19.5 (SD±2.9 slides with 12.8% positivity rate. The quality of Acid Fast Bacilli (AFB staining reagents was sub-standard. The overall agreement for blind rechecking of 1,123 AFB slides was 99.4% (Kappa = 0.97. Reading of 370 AFB panel slides showed 3.5% false reading (Kappa = 0.92. Moreover, the consistency of reading scanty bacilli slides was lower (93% compared to 1+, 2+ and 3+ bacilli. Based on blind rechecking and panel testing results, PPM-DOTS site laboratories showed good agreement with the reference laboratory. Physical space and qualities of AFB reagents would be areas of intervention to sustain the quality of sputum smear microscopy. Therefore, regular external quality assessment and provision of basic laboratory supplies for TB diagnosis would be the way forward to improve the quality of sputum smear microscopy services in PPM-DOTS laboratories.

    Results obtained in 43 Rheumatoid arthritis (RA) patients with cervical myelopathy are described; all patients showed several alarm signs together with neurological disturbances. Thirty-four cases were operable; nine patients were not operated upon for various reasons (refusal, and general condition). In the surgically treated patients, the changes were localized in the C1-C2 area (n = 20), in the area below C2 (n = 5), or in both (n = 9). The patients were put on skull traction pre- and post-operatively and nursed on a circo-electric bed. Pre-operatively, the duration of traction varied from a few days to weeks (mean 3 weeks). Post-operatively, the patients were given continuous skull traction for 2 1/2-3 months. This procedure yielded neurological improvement and a stable graft in all but two patients. On follow-up, recurrence of neurological complaints was seen in nine patients, in four due to a new slip at a lower level. Three of these cases were reoperated with good results. Twenty-three patients have died: four 'early' (one pre-operatively and three within 6 weeks post-operatively) and 19 'late'. The mean duration of follow-up was 4.5 years. In those who died 'late', the cause of death was due to the effects of an unstable graft in two cases and in the others the causes were not related to changes in the cervical spine. In the 10 patients who are still alive the mean duration of follow-up is 5 years. The nine patients who were not operated upon all died within a year, 4 of them due to consequences of cord compression. If cervical spondylodesis is feasible in an RA patient with myelopathy, the procedure is advocated. PMID:6529877

Most LBC systems though require expensive automated devices. Aims: To evaluate the efficiency of a new and inexpensive LBC system - LPT cytology system. Materials and Methods: Cervical screening was performed on 31500 patients utilizing the LPT cytology system test from January 2006 to May 2007. A similar number (n = 31500 of CPS were performed from January 2004 to July 2006. All cytology positive patients underwent colposcopy and cervical biopsy with histopathology examination. Fifty cases positive both on cytology and biopsy were submitted to the high-risk human papillomavirus (HPV L1 protein (HR-HPV L1 tests. Results: The LPT cytology system adequately preserved cellular structure for morphologic evaluation. There was a significant difference of the histology/cytology diagnosis concordant rate between that of the CPS and LPT systems [93.6 vs. 78.4%, p=0.001]. The significant higher concordant rate was also seen in the low grade intraepithelial lesion (LSIL (95.4 vs. 78.9%, p=0.001 and in high grade intraepithelial lesion (HSIL (90.2 vs. 76.1%, p=0.001 cytology diagnosis. There was no statistical difference in rate in atypical glandular cells (AGC (61.5 vs. 60% and glandular cell carcinoma (GCC (83.3 vs. 80%. LPT resulted in a marked increased global detection over the CPS. Nuclear expression of HPV L1 was seen in 34% (17/50 of cases. Conclusions: LPT showed an increase in detection rate compared to CPS (P = 0.001 and a significantly higher histological versus cytological concordant referral rate.

    In the absence of any nationwide cervical screening program, cancer of cervix remains a major public health problem for India. We here assessed knowledge levels of female college students about cervical cancer, its risk factors, the human papillomavirus (HPV) etiologic agent and Pap (Papanicolaou) smear testing for screening. We conducted a questionnaire survey of the students (N=630), aged 17 to 24 years, in Kolkata, India. Only 20% correctly identified cervix cancer as the most prevalent female cancer in India, while 43% were aware of the ages of occurrence. Though 41% thought sexual activity to be associated with cervical cancer, its risk factors, like, smoking, having multiple sex partners, cervical infections, early onset of sexual intercourse, multiple parity were recognized by 29%, 3%, 4%, 13% and 15%, respectively. The terms Pap test and HPV had been heard by 11% and 15 % of the students, respectively, and 75% of the students desired to have protective vaccination. Bivariate analysis revealed that educational stream, standard of the college and family size were significantly associated with knowledge levels. Additionally, multivariate regression analysis indicated city students were more knowledgeable than those from outside the city. It is imperative that women gather adequate knowledge on cervical cancer for the success of any program to control the disease. Wide and effective spreading of awareness about the disease among women must form an integral part of public health policy of government. PMID:21133629

  16. Exfoliative cytology in study of radiosensitivity of uterine cervical cancer, (2)

    International Nuclear Information System (INIS)

    In this paper, we discuss the possibility of cytological judgment of radiosensitivity of uterine cervical cancer by comparison between pre- and post-irradiation smears given 1,000 rads by telecobalt external test irradiation. The estimation of radiation effects on nuclei and the cytological presumption of histological typing in pre-irradiation smears have brought about satisfactory results; agreement between histological and cytological judgements of radiosensitivity was about 96.8%. Cytological criteria of good sensitivity are as follows; Disparity in size of chromatin particles and irregular distribution. Irregularity of nuclear membrane with nuclear wrinkling with diminution of thickness of nuclear membrane. Mature squamous cell carcinoma without pearl formation. Those of poor sensitivity are as follows; Existence of many unchanged viable cells and less disturbances of chromatines. Existence of cells exibiting adenocarcinoma and carcinoma of intermediate type. Clusters of cyanophilic cells having lacy, indistinct cell borders. (auth.)

    The biomarker discovery for accurate detection and diagnosis of cervical carcinoma and its malignant precursors represents one of the current challenges in clinical medicine. Laser induced autofluorescence spectra in cervical smear content were fitted to predict the cervical epithelium diagnosis as a lab off "optical biopsy" method. Liquid PAP supernatant sediment dried on Quartz plate spectroscopy was performed by 355 nm Nd YAG microlaser STA-1 (Standa, Ltd). For comparison a liquid supernatant spectroscopy was formed by laboratory "Perkin Elmer LS 50B spetrometer at 290, 300, 310 nm excitations. Analysis of spectrum was performed by approximation using the multi-peaks program with Lorentz functions for the liquid samples and with Gaussian functions for the dry samples. Ratio of spectral components area to the area under whole experimental curve (SPP) was calculated. The spectral components were compared by averages of SPP using Mann-Whitney U-test in histology groups. Results. Differentiation of Normal and HSIL/CIN2+ cases in whole supernatant could be performed by stationary laboratory lamp spectroscopy at excitation 290 nm and emission >379 nm with accuracy AUC 0,69, Sens 0,72, Spec 0,65. Differentiation Normal versus HSIL/CIN2+ groups in dried enriched supernatant could be performed by 355 nm microlaser excitation at emission 405-424 nm with accuracy (AUC 0,96, Sens 0,91, Spec 1.00). Diagnostic algorithm could be created for all histology groups differentiation under 355 nm excitation. Microlaser induced "optical biopsy "looks promising method for cervical screening at the point of care.

    Full Text Available OBJECTIVE To analyze the coverage of a cervical cancer screening program in a city with a high incidence of the disease in addition to the factors associated with non-adherence to the current preventive program. METHODS A cross-sectional study based on household surveys was conducted. The sample was composed of women between 25 and 59 years of age of the city of Boa Vista, RR, Northern Brazil who were covered by the cervical cancer screening program. The cluster sampling method was used. The dependent variable was participation in a women’s health program, defined as undergoing at least one Pap smear in the 36 months prior to the interview; the explanatory variables were extracted from individual data. A generalized linear model was used. RESULTS 603 women were analyzed, with an mean age of 38.2 years (SD = 10.2. Five hundred and seventeen women underwent the screening test, and the prevalence of adherence in the last three years was up to 85.7% (95%CI 82.5;88.5. A high per capita household income and recent medical consultation were associated with the lower rate of not being tested in multivariate analysis. Disease ignorance, causes, and prevention methods were correlated with chances of non-adherence to the screening system; 20.0% of the women were reported to have undergone opportunistic and non-routine screening. CONCLUSIONS The informed level of coverage is high, exceeding the level recommended for the control of cervical cancer. The preventive program appears to be opportunistic in nature, particularly for the most vulnerable women (with low income and little information on the disease. Studies on the diagnostic quality of cervicovaginal cytology and therapeutic schedules for positive cases are necessary for understanding the barriers to the control of cervical cancer.

    Full Text Available Background: Objectives of current study were to evaluate visual inspection of cervix with acetic acid in picking up abnormal cervix and to correlate the findings of VIA with Pap smear, colposcopy and cervical biopsy. Methods: Study was conducted on 300 sexually active women attending the gynaecological OPD at Dayanand medical college and hospital, Ludhiana. All patients underwent VIA and Pap smear screening and if either of the two was abnormal, colposcopy was done and colposcopic guided cervical biopsy was taken if indicated. Total 105 colposcopies were done. Cervical biopsy was taken in 87 cases and the results were compared and statistically analysed. Results: The sensitivity of VIA was 86% and specificity 40.50%. No case was missed by VIA when cut off was taken as moderate dysplasia or higher lesions on biopsy. Conclusions: VIA is a sensitive, practical and a low cost affair in cervical cancer screening.

    Full Text Available BACKGROUND: Direct sputum smear microscopy for tuberculosis (TB lacks sensitivity for the detection of acid fast bacilli. Sputum pretreatment procedures may enhance sensitivity. We did a pilot study to compare the diagnostic accuracy and incremental yield of two short-duration (<1 hour sputum pretreatment procedures to optimize direct smears among patients with suspected TB at a referral hospital in India. METHODOLOGY/FINDINGS: Blinded laboratory comparison of bleach and universal sediment processing (USP pretreated centrifuged auramine smears to direct Ziehl-Neelsen (ZN and direct auramine smears and to solid (Loweinstein-Jensen (LJ and liquid (BACTEC 460 culture. 178 pulmonary and extrapulmonary TB suspects were prospectively recruited during a one year period. Thirty six (20.2% were positive by either solid or liquid culture. Direct ZN smear detected 22 of 36 cases and direct auramine smears detected 26 of 36 cases. Bleach and USP centrifugation detected 24 cases each, providing no incremental yield beyond direct smears. When compared to combined culture, pretreated smears were not more sensitive than direct smears (66.6% vs 61.1 (ZN or 72.2 (auramine, and were not more specific (92.3% vs 93.0 (ZN or 97.2 (auramine. CONCLUSIONS/SIGNIFICANCE: Short duration sputum pretreatment with bleach and USP centrifugation did not increase yield as compared to direct sputum smears. Further work is needed to confirm this in a larger study and also determine if longer duration pre-treatment might be effective in optimizing smear microscopy for TB.

    Taurayi A Tafuma

    Full Text Available BACKGROUND: Diagnosis of smear negative pulmonary tuberculosis (SNPTB is challenging, especially in patients with HIV. The Botswana National Tuberculosis Program (BNTP guidelines give guidance in diagnosing and treating SNPTB. Patients with chronic cough should be screened for TB by 3 sputum smear investigations. If negative, a chest x-ray (CXR should be performed. If negative for TB, antimicrobial treatment for other infections should be started. We investigated the clinicians' use of the guidelines in clinical practice. METHODS: Data regarding the medical history (coughing period, requested and conducted investigations concerning tuberculosis diagnosis (sputum smear or culture or CXR or alternative diagnoses (sputum microscopy or blood or sputum culture for diagnosis of other organisms, in SNPTB HIV-positive patients (outpatients and admitted patients from 2006-2009 in a district hospital in Botswana were extracted from all available hospital medical records. Additionally, a survey was done in all doctors diagnosing SNPTB in this hospital using a self-administered questionnaire with questions regarding the application of the BNTP guidelines in practice. Descriptive analyses of collected data were performed to test the compliance to the guidelines. RESULTS: Data from medical records showed that in 47.0% (132/281 of patients, TB treatment was started without microbiological results from sputum smears. Other methods to rule out or confirm PTB were used in 2.1% (6/281; and 99.6% (280/281 of SNPTB patients had received a CXR. The survey in 7 clinicians found that all always used CXR, and all clinicians requested three sputum results only sometimes. Six out of 7 clinicians started antibiotics before starting TB treatment. Reasons clinicians gave for difficulties in following the guidelines included inability of patients to produce sputum; and laboratory delays in releasing sputum results. CONCLUSION: Between 2006 and 2009 a high proportion of SNPTB

    Full Text Available Abstract Background Sentinel lymph node (SLN biopsy is performed at many institutions and is considered a standard of care in the management of cutaneous melanoma. The discriminatory immunostaining pattern with the 'MCW Melanoma Cocktail' (a mixture of MART-1 {1:500}, Melan- A {1:100}, and Tyrosinase {1:50} monoclonal antibodies allows intraoperative immunocytochemical evaluation of imprint smears of SLNs for melanoma metastases. Cohesive cells of benign capsular melanocytic nevi that were also immunoreactive with the cocktail do not exfoliate easily for imprint smear detection. Methods We prospectively evaluated 73 lymph nodes (70 SLN & 3 non-SLN from 41 cases (mean 1.8, 1 to 4 SLNs/case of cutaneous melanoma using a rapid 17-minute immunostaining previously published protocol. The results were compared with permanent sections also immunostained with 'the cocktail'. Results 19.5%, 8/41 cases (12%, 9/73 lymph nodes were positive for melanoma metastases on permanent sections immunostained with the 'MCW melanoma cocktail'. Melanoma metastases in 87.5% (7/8 of these cases were also detected in rapidly immunostained imprint smears, with 100% specificity and 90% sensitivity. None of the 7 SLNs from 7 cases with capsular nevi showed false positive results. Conclusion Melanoma metastases could be detected in imprint smears immunostained with 'MCW Melanoma Cocktail' utilizing a rapid intraoperative protocol. The cohesive cells of the capsular nevi do not readily exfoliate and do not lead to false positive interpretation. In a majority of positive cases, a regional lymphadenectomy could have been completed during the same surgery for SLN biopsy and wide excision of primary melanoma site, potentially eliminating the need for an additional surgery.

    suspected cervical neoplasia and to compare it with young adult women. METHODS: a cross-sectional, retrospective study that analyzed 366 medical records of females referred to clarify diagnosis of the suspected cervical neoplasia. The patients had been classified into two groups defined by age. The Adolescent group was composed of 129 females between 13 and 19 years and the Adult group was composed of 237 females between 20 and 24 years. Data were analyzed statistically by the prevalence ratio (PR, respective confidence intervals (CI at 95% for each variable, chi2 test, or Fisher exact test used to compare proportion. RESULTS: the first sexual intercourse coitarche occurred on average at 15.0 years in the Adolescent group and 16.6 years in the Adult group. The possibility of diagnosis of cytological alterations in the first Papanicolaou smears (PR=2.61; CI 95%: 2.0-3,4, the condition of non-clarified cervical intraepithelial neoplasia (CIN (PR=1.78; CI 95%: 1.26-2,52, and the colposcopic impressions of low grade (PR=1.42; CI 95%: 1.08-1.86 were statistically significant in the Adolescent group. The histopathologic analysis did not show differences at any grade of CIN. However, two cases of microinvasive carcinoma, one in each group, and three cases of clinical invasive carcinoma in the Adult group were identified. CONCLUSION: our study suggests that cervical cancer is rare among adolescents, but we verified that alterations associated with it occurred even in younger women. The evaluation of cervical intraepithelial neoplasia with the careful application of the same tools used for adult women was appropriate also in adolescence.

  4. Protein p16 as a marker of dysplastic and neoplastic alterations in cervical epithelial cells

    International Nuclear Information System (INIS)

    Cervical carcinomas are second most frequent type of women cancer. Success in diagnostics of this disease is due to the use of Pap-test (cytological smear analysis). However Pap-test gives significant portion of both false-positive and false-negative conclusions. Amendments of the diagnostic procedure are desirable. Aetiological role of papillomaviruses in cervical cancer is established while the role of cellular gene alterations in the course of tumor progression is less clear. Several research groups including us have recently named the protein p16INK4a as a possible diagnostic marker of cervical cancer. To evaluate whether the specificity of p16INK4a expression in dysplastic and neoplastic cervical epithelium is sufficient for such application we undertook a broader immunochistochemical registration of this protein with a highly p16INK4a-specific monoclonal antibody. Paraffin-embedded samples of diagnostic biopsies and surgical materials were used. Control group included vaginal smears of healthy women and biopsy samples from patients with cervical ectopia. We examined 197 samples in total. Monoclonal antibody E6H4 (MTM Laboratories, Germany) was used. In control samples we did not find any p16INK4a-positive cells. Overexpression of p16INK4a was detected in samples of cervical dysplasia (CINs) and carcinomas. The portion of p16INK4a-positive samples increased in the row: CIN I – CIN II – CIN III – invasive carcinoma. For all stages the samples were found to be heterogeneous with respect to p16INK4a-expression. Every third of CINs III and one invasive squamous cell carcinoma (out of 21 analyzed) were negative. Overexpression of the protein p16INK4a is typical for dysplastic and neoplastic epithelium of cervix uteri. However p16INK4a-negative CINs and carcinomas do exist. All stages of CINs and carcinomas analyzed are heterogeneous with respect to p16INK4a expression. So p16INK4a-negativity is not a sufficient reason to exclude a patient from the high risk

    Cervical spondylotic myelopathy(CSM) is the most common cause of spinal cord dysfunction and is caused by static or dynamic repeated compression of the spinal cord resulting from degenerative arthritis of the cervical spine and some biological injuries to the cervical spine. The T2 signal change on conventional magnetic resonance imaging(MRI) is most commonly associated with neurological deficits. Diffusion tensor imaging and MR spectroscopy show altered microstructure and biochemistry that reflect patient-specific pathogenesis and can be used to predict neurological outcome and response to intervention. Functional MRI can help to assess the neurological functional recovery after decompression surgery for CSM.

    This research investigates the interrelationships between cancer risk perceptions (absolute and comparative risk perceptions), cancer worry, and cervical cancer screening. Using a nationally representative survey data set (N = 2,304) from the 2012 Health Information National Trends Survey Circle 1, we found that although neither absolute risk perceptions nor comparative risk perceptions exerted a direct impact on women's compliance with the cervical cancer screening recommendation (i.e., that women ages 21 to 65 obtain Pap smear every 3 years; U.S. Preventive Services Task Force, 2012 ), both types of risk perceptions had an indirect effect on cervical cancer screening through the mediation of cancer worry. These results suggest a primal role of affect in health decision making. Implications of the findings for cancer risk communication are discussed. PMID:26312444

  12. Accessibility of breast and cervical cancer services in Malaysia.

    Science.gov (United States)

    1997-12-01

    Despite the fact that Malaysia has good treatment centers for reproductive cancer, mortality rates from breast and cervical cancer are high because of a lack of early detection. Breast cancer mortality rates have risen since 1985, while cervical cancer mortality rates declined from 1985 to 1993 and then increased in 1997. There is no standardized cancer registry, so incidence and mortality rates are likely to be higher than reported. In 1995, the government launched its first nationwide cancer prevention campaign and stressed breast self-examination and yearly examination by a medical professional for woman aged 20 years and above. The same year, eligibility for pap smears was extended to all women who have been or are sexually active and are aged 20-65 years. Between 1993 and 1996, 35% of the breast cancer cases presented at stage 3 or 4, and 93% of these women had a lump of a mean size of 5.3 cm. Cultural taboos prevent women from examining their own bodies, and women fear their husbands will leave them if they have a mastectomy. Malay women also deny themselves preventive care, and sometimes physicians and nurses deny Pap smears to unmarried women. Women are not empowered with the knowledge they need to seek preventive screenings, and older women are difficult to reach with information because they are unlikely to visit maternal-child health or family planning clinics. Malaysia needs to institute a standardized cancer registry and to conduct research that will address the barriers faced by women. PMID:12294552

    Full Text Available AIMS : Prevalence of Sexually transmitted infections (STIs tends to be high which constitutes an important public health problem at present worldwide and in India, being associated with Human Immunodeficiency virus and predisposing to cervical dysplasia and cancer. There is a need to overcome the STI infections throughout the nation by cytological and microbiological screening. SETTING AND DESIGN : The present study was undertaken to investigate the association of Chlamydia trachomatis (CT, Herpes simplex virus 2 (HSV 2, Cytomegalovirus (CMV, Hepatitis B (HBV, Hepatitis C virus (HCV, Trichomonas vaginalis (TV and Candidiasis with cervical cytological changes in symptomatic female in West Bengal. METHOD S : Sera and vaginal samples from 431 syndromic female patients with cervico - vaginal discharge were tested for detection of STIs. The study period extended over two years. Concomitantly, study of cervical cytology on Papanicolaou stained smears was performed in all cases. ELISA was performed for detection of CT IgM, HSV2 IgM, CMV IgM, HBsAg and HCV IgM in sera. Candida spp. and TV were identified by culture of vaginal samples. Cytological findings were interpreted according to Bethesda 2001 classification. Statistical analysis was performed using MedCalc for Windows, version 13.3.1.0 (MedCalc Software, Ostend, Belgium. RESULTS: Out of 431 samples, majority of the patients belonged to the age group of 29 to 42 years, however the mean age of patients presenting with HSIL on PAP was 45 ± 7.93 years. CT, HSV2, TV and Candida spp. were associated with cervical cytological changes of ASCUS or worse. Age greater than 40 years and infection with CT emerged independent risk factors associated with cervical dysplasia on univariate and multivariate analysis with p <0.05 in both. CONCLUSION : C. trachomatis is a risk factor for cervical dysplasia. Early detection and treatment will prevent progression of STIs and development of cervical dysplasia and

  15. Relationships between radiography of cervical vertebrae and histopathology of the cervical cord in wobbling 19 foals

    International Nuclear Information System (INIS)

    Nineteen wobbling foals (17 males and 2 females) showing lameness of hindlimbs at 6 to 21 months of age were investigated radiographically and histopathologically. Minimum sagittal diameter (MSD), minimum flexion diameter (MFD) and minimum dural sagittal diameter (MDD) were measured on plain radiograms or myelograms taken at neutral and flexed positions as indicators of narrowed vertebral canal. After necropsy, the cervical spines and the spinal cord were examined macroscopically and respectively the relationships between radiographic findings and the corresponding morphological lesions were evaluated. Radiographically, lower values than each minimum reference limits were recorded in 14 foals in MSD, 5 foals in MFD and 6 foals in MDD, respectively. According to the histopathologic examination, the disappearance of axons and myelin sheaths, vacuolated spongy degeneration and appearance of macrophages were recognized symmetrically in the white matter of the cervical cord. These lesions were centrally located at the spinal cord radiographically demonstrated as compressed sites in 12 out of 17 foals examined. Macroscopically, asymmetrical overgrowth of one side of the process, encroachment of articular processes into the intervertebral foramina and proliferation of bone around articular facets were observed in the articular processes of bone specimens in the caudal neck of 6 foals. In conclusion, the equine incoordination might mainly be caused by the cervical stenotic myelopathy resulting from cervical vertebral malformation, and therefore the cervical vertebral radiography, especiallymyelography, is quite very important and effective for the diagnosis of wobbling foals

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Objective:To investigate a novel surgical method for multilevel cervical spondylotic myelopathy (CSM). Methods: Totally 21 patients with multilevel CSM undergoing a novel surgical procedure from April 2001 to January 2004 were analyzed retrospectively. All patients experienced anterior cervical decompression surgery in subsection, autograft fusion and internal fixation. Preoperative, immediate postoperative and follow-up image data, X-rays and semi-quantitative Japanese orthopaedics association (JOA) scores were used to evaluate the restoration of lordosis (Cobb's angle), intervertebral heights, the stability of the cervical spine and the improvement of neurological impairment. Results: Preoperative symptoms were markedly alleviated or disappeared in most of the patients. According to the JOA scores, the ratio of improvement in neurological function was 72.2%, including excellent in 9 cases (42.9%), good in 7 cases (33.3%), fair in 3 cases (14.3%) and poor in 2 cases (9.5%). Immediate postoperative X-rays showed obvious improvements in lordosis and in the intervertebral height of the cervical spine (P<0.01). There is no evidence of instrument failure during the mean follow-up period of 14.2 months (9-24 months, P>0.01). Conclusion:Anterior cervical decompression in subsection, autograft fusion and internal fixation is a rational effective method for the surgical treatment of multilevel CSM.

    Objective was to describe the radiographic cervical spine changes in rheumatoid arthritis patients.Forty-nine patients (37 females and 12 males ) diagnosed with rheumatoid arthritis at King Khalid University Hospital, Riyadh, Kingdom of Saudi Arabia between June 1998 and December 2000, were studied for their radiographic cervical spine changes . Their mean age at disease onset was 41.4+ 13.4 years (range of 18-73)and mean duration of disease was 9.1+-6.28 years (range of 2-34). Their demographic data including rheumatoid factor status was obtained. Standard conventional radiographs cervical spine were obtained to study the cervical spine changes. Cervical radiographic changes were found in 34 patients (27 females and 7 males) 10 had subluxation (7 with atlanto-axial subluxation,2 with sub-axial subluxation,and one with lateral subluxation ). No vertical impaction was seen. Erosion of odontoid process was seen in one patient .All were rheumatoid seropositive Cervical spine changes in patients with rheumatoid arthritis are common, in particular subluxation in the upper cervical spine. Our study showed somewhat lesser prevalence of these changes. These were clinically correlated with disease duration, female sex, and rheumatoid factor, but were not clinically significant. (author)

    Full Text Available Background: Cervical cancer is the second leading cause of morbidity and mortality among the females worldwide. India has the highest burden of cervical cancer patients, accounting for approximately one-fifth of the cases in world. Nurses being an important link between the doctors and female patients in OPD or wards, it is imperative that they should be aware of the facts about cervical cancer and especially of screening techniques which can be utilized in low-resource settings. Methods: A cross-sectional interview based study was done among 200 nurses of a tertiary care teaching institute from June 2013 to July 2013, to assess the knowledge and awareness of nursing staff regarding causes of cervical cancer and its prevention and early detection. Results: Among all participated nurses, 85% (n=170 were aware of the term cancer cervix and 45% reported that it is the most frequent gynaecological cancer in India. Only 30.6% reported that it is the leading cause of death among women due to cancer. Young age at first intercourse, multiple sex partners, cigarette smoking, high parity and lower socio-economic status were correctly responded by 13%, 48%, 16%, 9% and 13% of participants respectively, as risk factors for cervical cancer. None of the participants knew about the VIA method of screening for cervical cancer. Among 119 of those participants who knew that cervical cancer can be detected by Pap smear, only 5 (4% had ever undergone Pap smear examination. Conclusions: Nurses identify certain aspects of cervical cancer correctly but their knowledge is not adequate, hence necessary changes should be made in their curriculum.

    Conventional analysis of a cervical histology image, such a pap smear or a biopsy sample, is performed by an expert pathologist manually. This involves inspecting the sample for cellular level abnormalities and determining the spread of the abnormalities. Cancer is graded based on the spread of the abnormal cells. This is a tedious, subjective and time-consuming process with considerable variations in diagnosis between the experts. This paper presents a computer aided decision support system (CADSS) tool to help the pathologists in their examination of the cervical cancer biopsies. The main aim of the proposed CADSS system is to identify abnormalities and quantify cancer grading in a systematic and repeatable manner. The paper proposes three different methods which presents and compares the results using 475 images of cervical biopsies which include normal, three stages of pre cancer, and malignant cases. This paper will explore various components of an effective CADSS; image acquisition, pre-processing, segmentation, feature extraction, classification, grading and disease identification. Cervical histological images are captured using a digital microscope. The images are captured in sufficient resolution to retain enough information for effective classification. Histology images of cervical biopsies consist of three major sections; background, stroma and squamous epithelium. Most diagnostic information are contained within the epithelium region. This paper will present two levels of segmentations; global (macro) and local (micro). At the global level the squamous epithelium is separated from the background and stroma. At the local or cellular level, the nuclei and cytoplasm are segmented for further analysis. Image features that influence the pathologists' decision during the analysis and classification of a cervical biopsy are the nuclei's shape and spread; the ratio of the areas of nuclei and cytoplasm as well as the texture and spread of the abnormalities

    Touching Mycobacterium tuberculosis objects in the Ziehl-Neelsen stained sputum smear images present different shapes and invisible boundaries in the adhesion areas, which increases the difficulty in objects recognition and counting. In this paper, we present a segmentation method of combining the hierarchy tree analysis with gradient vector flow snake to address this problem. The skeletons of the objects are used for structure analysis based on the hierarchy tree. The gradient vector flow snake is used to estimate the object edge. Experimental results show that the single objects composing the touching objects are successfully segmented by the proposed method. This work will improve the accuracy and practicability of the computer-aided diagnosis of tuberculosis.
