Study of Cervical PAP Smear in a Tertiary Care Hospital

Introduction: Sepsis in elderly patients is a critical clinicalissue due to high rates of morbidity and mortality. The modernage cell counters precisely measure volume, size and internalstructure of the cell thereby assessing increase in volumeand cytoplasmic granularity of leukocytes as seen in casesof sepsis. The present study was done to evaluate the useof Volume Conductivity Scatter (VCS) parameters as earlyindicators of sepsis in elderly patients and to overcome theshortcomings of blood culture by using a more precise VCStechnology to assess morphologic changes in cell populationsin sepsis.Material and Method: The study included 51 patients abovethe age of 50 years which were divided into 2 groups Group1, patients with localised infection (n= 39) and Group 2 withsystemic infection (n=12). Group 3 included 30 controlswithout any signs of infection and with total leucocyte countand differential counts within normal limits. Coulter LH 750cellular analysis system was used.Result: Significant increase in both mean neutrophil volume(MNV) and mean monocyte volume (MMV) was reportedamong the patients with sepsis as compared to localizedinfections or control. With a cut off of 145 and 170 for MNVand MMV respectively, a sensitivity of 96% and 91.4% wasobtained in predicting sepsis.Conclusion: Both MNV and MMV have the potential to beused as early indicators of acute bacterial infections.

Role of Pap smear in detection of precancerous lesions of cervix-A case study

Background: The pap smear is the screening test for the detection of premalignant lesion of the cervix. It should be done annually in all women of age 35 years and above. Pap smear screening of cervix can significantly reduce the deaths due to cervical carcinoma. Materials and methods: This was a prospective and descriptive study done for the period of 6 months from February 2018 to July 2018. A total of 158 women above the age of 21 years and married were included in the study. A Pap smear test was done after clinical examination in all women and sent to the department of Pathology of our tertiary care centre for cytopathological examination. Results: There were 150 cases with inflammatory smear, 2 cases of ASCUS, 3 cases of LSIL and 3 cases of HSIL. Women who were positive for ASCUS, LSIL and HSIL underwent colposcopy and guided biopsy. Most women with inflammatory smear were of age group 20-40 years, 2cases of ASCUS were of ages 35 years and 38 years, 3cases of LSIL were of age group 35-45 years and 3 cases of HSIL were of age group 45-55years. Conclusion: Thus cervical cancer is a preventable cancer if regular Pap smear screening test is done. It is simple, cost effective, non-invasive and easy to perform screening test for precancerous lesions of cervix.

Comparison of the PANArray HPV Genotyping Chip Test with the Cobas 4800 HPV and Hybrid Capture 2 Tests for Detection of HPV in ASCUS Women

PURPOSE: This study aimed to evaluate the performance of the PANArray human papilloma virus (HPV) test, a PCR-based DNA microarray assay, in detecting HPV from patient samples and its concordance with the cobas 4800 HPV and Hybrid Capture 2 (HC2) tests. MATERIALS AND METHODS: The PANArray HPV, cobas 4800 HPV, and HC2 tests were performed on 504 cervical swab samples from patients with atypical cells of undetermined significance at five hospitals. The samples that were interpreted as ‘HPV-other’ type positive in the PANArray HPV test were confirmed by direct sequencing. RESULTS: The concordance rates were 80.8% between the cobas 4800 HPV and PANArray HPV tests [κ=0.59, 95% confidence interval (CI) 0.52–0.66] and 80.2% (κ=0.6, 95% CI 0.55–0.68) between the HC2 and PANArray HPV tests. Among the 62 patients negative on PANArray HPV (defined as the absence of high risk HPV), but positive on both cobas 4800 HPV and HC2 tests, 42 (67.7%) tested positive for ‘HPV-other’ types on the PANArray HPV test, and 31 (50.0%) had gray zone results [relative light unit/control (RLU/CO), 1.4–9.25] in the HC2 test. Of the patients deemed positive by the PANArray HPV test, 43 tested positive for high-risk (HR) HPV in cobas 4800 HPV and HC 2 tests. Among them, 58.2% showed HR HPV, including HPV 16, by direct sequencing, of which 25% had gray results. CONCLUSION: Results classified as ‘HPV-other’ type by the PANArray HPV test, or gray zone results by HC2 (RLU/CO ratio level 1–10) should be carefully interpreted using comprehensive clinical information.

Geometría fractal y euclidiana aplicada al diagnóstico de grados de lesión de células de cuello uterino

Previamente, se desarrolló una metodología diagnóstica para lesiones preneoplásicas y neoplásicas de células de cuello uterino, a partir de medidas euclidianas y fractales simultáneas. En este trabajo, el objetivo era confirmar la concordancia diagnóstica de la metodología en células normales y en diferentes estadios de lesión celular. Se tomaron fotografías de 60 células del epitelio escamoso cervical: 10 normales, 10 ASCUS, 20 con lesión intraepitelial de bajo grado (LEIBG) y 20 con lesión de alto grado (LEIAG). Se realizaron medidas de dimensión fractal y del espacio de ocupación de la superficie y el borde del núcleo y citoplasma en el espacio fractal de Box Counting, estableciendo su diagnóstico físico-matemático. Las medidas de la superficie del núcleo estuvieron para normalidad, entre 305 y 651; para ASCUS, entre 1293 y 4588; para LEIBG, entre 986 y 4873 y para LEIAG, entre 567 y 2311. La resta de las fronteras Citoplasma-Núcleo, se encontró entre 238 y 477, para normalidad; entre 185 y 417, para ASCUS; entre 131 y 342, para LEIBG y entre 43 y 117, para LEIAG. Fueron hallados valores de sensibilidad y especificidad del 100%; la razón de probabilidad fue de 0 y el coeficiente kappa de 1. Se confirmó la concordancia diagnóstica a nivel clínico del método físico-matemático, cuantificando de manera objetiva y reproducible el grado de lesión de células de cérvix y estableciendo un diagnóstico objetivo para las células ASCUS, a partir de medidas fractales y euclidianas simultáneas, que mejora los métodos cualitativos de clasificación.

A diagnostic methodology for preneoplastic and neoplastic lesions of cervical cells from simultaneous fractals and euclidean measures was developed. In this work the objective was to confirm the diagnostic concordance of the methodology in normal cells and in different stages of progression to disease. For this, 60 photographs of cervical squamous epithelium cells were taken: 10 normal, 10 ASCUS, 20 with low grade - squamous intraepithelial lesion (L-SIL) and 20 high-grade lesion (H-SIL). Measures of fractal dimension and space occupancy of the surface and the edge of the nucleus and cytoplasm were performed in Box Counting Fractal space, establishing their physical-mathematical diagnosis. Measurements of the nucleus surface for normality were between 305 and 651, for ASCUS between 1293 and 4588, for L-SIL, between 986 and 4873 and for H-SIL between 567 and 2311. The subtraction of Cytoplasm-Nucleus border was found between 238 and 477 for normality; between 185 and 417 for ASCUS; between 131 and 342 for L-SIL and between 43 and 117 for H-SIL, finding sensitivity and specificity of 100%, likelihood ratio of 0 and kappa coefficient of 1. Conclusions: the diagnostic concordance at clinical level of the physical-mathematical method was confirmed, objective and reproducible quantifying the degree of injury of cervical cells and establishing an objective diagnosis for ASCUS cells from simultaneous fractals and euclidean measures, which improves qualitative classification methods.

Objectives To enhance the diagnosis of cervical epithelial neoplasia and cervical cancer at the early stage and to prevent cervical invasive carcinoma by analyzing the cervical/vaginal cytology or histopathologic results of Atypical squamous cells of undetermined significance (ASCUS).Methods From January 2014 to June 2015,a total of 4579 cases were selected in the census of gynecological diseases in Qiannan Hospital.TBS classification (the bethesda system) showed that 164 cases of ASCUS or above were found using cervical/vaginal cytology with live tissue under colposcopy.Results Among 164 cases,75 was cervical intraepithelial neoplasia level 3 (CINⅢ) accounting for 54.7％.Sixty-three cases of ASCUS and 16 of CINⅡ or above were found among patients at the age of 39 or younger (25.4％).A hundred and one cases of ASCUS and 59 of CINⅡ or above were found among women older than 40 (58.41％).Among patients with liquid-based cervical cytology positive,those older than 40 had higher risk.Liquid-based cervical cytology examination was divided into 5 levels.Spearman rank correlation analysis was applied with correlation coefficient (r =1) and positive correlation was shown (P =0.000,P＜0.01).The difference was statistically significant.The higher level of liquid-based cervical cytology examination level was required,the higher risk of cervical cancer was seen among women.Corclusion The use of liquid-based cervical cytology examination can help grassroots doctors improve CIN diagnosis rate and prevent cervical invasive carcinoma among women in the countryside.

Diagnostic Algorithm to Reflect Regressive Changes of Human Papilloma Virus in Tissue Biopsies

PURPOSE: Landmark indicators have not yet to be developed to detect the regression of cervical intraepithelial neoplasia (CIN). We propose that quantitative viral load and indicative histological criteria can be used to differentiate between atypical squamous cells of undetermined significance (ASCUS) and a CIN of grade 1. MATERIALS AND METHODS: We collected 115 tissue biopsies from women who tested positive for the human papilloma virus (HPV). Nine morphological parameters including nuclear size, perinuclear halo, hyperchromasia, typical koilocyte (TK), abortive koilocyte (AK), bi-/multi-nucleation, keratohyaline granules, inflammation, and dyskeratosis were examined for each case. Correlation analyses, cumulative logistic regression, and binary logistic regression were used to determine optimal cut-off values of HPV copy numbers. The parameters TK, perinuclear halo, multi-nucleation, and nuclear size were significantly correlated quantitatively to HPV copy number. RESULTS: An HPV loading number of 58.9 and AK number of 20 were optimal to discriminate between negative and subtle findings in biopsies. An HPV loading number of 271.49 and AK of 20 were optimal for discriminating between equivocal changes and obvious koilocytosis. CONCLUSION: We propose that a squamous epithelial lesion with AK of >20 and quantitative HPV copy number between 58.9-271.49 represents a new spectrum of subtle pathological findings, characterized by AK in ASCUS. This can be described as a distinct entity and called "regressing koilocytosis".

Distribution of human papillomavirus genotypes in women with cervical alterations from north Argentina.

Background: Cervical cancer remains a major public health problem in northern Argentina, showing the highest mortality rate in the country (approximately 22 cases/100000 women). Objective: The aim of this study was to provide epidemiological data on the prevalence and type distribution of human papillomavirus (HPV) in women with pre-neoplastic lesions before the massive introduction of HPV vaccination in the country. Materials and Methods: Exfoliated cervical cells were collected to screen for HPV using the widely known MY09/11 PCR, followed by the restriction fragment-length polymorphism (RFLP) technique from a total of 714 women with previously diagnosed atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesion (LG-SIL) and high-grade squamous intraepithelial lesion (HG-SIL). Results: Overall HPV prevalence was 48.2% in ASCUS (24 different HPV types detected), 66.5% in LG-SIL (37 HPV types detected) and 82.6% in HG-SIL (16 HPV types detected). HPV-16 was the most prevalent type among all cases. With respect to multiple HPV infections, 9.6% were observed in ASCUS, 14.3% in LG-SIL and 11.4% in HG-SIL. Conclusion: The major strength of our study is the assessment of a large series of women with cytological alterations in this region. The information attained will be useful as a regional baseline for future epidemiological vigilance, in the context of the national HPV vaccination program.

Occurrence of Ureaplasma parvum and Ureaplasma urealyticum in Women with Cervical Dysplasia in Katowice, Poland

The aim of this study was to evaluate the occurrence of genital mycoplasmas, especially Ureaplasma parvum and Ureaplasma urealyticum, in women with atypical squamous cells of undetermined significance (ASCUS), low grade squamous intraepithelial lesions (LSIL) and high grade squamous intraepithelial lesions (HSIL), compared to women with normal cytology living in Katowice, Poland. Two sterile swabs were used to obtain material from the posterior vaginal fornix of 143 women with squamous intraepithelial lesions and 39 healthy women: first for general bacteriology, second for detection of urogenital mycoplasmas using Mycoplasma IST2 kit. From each positive Mycoplasma IST2 culture DNA was isolated and PCR was performed for identification of U. parvum and U. urealyticum. Mycoplasma IST was positive in 34.1% cases. Urogenital mycoplasmas were demonstrated in women with HSIL significantly more often compared to women with LSIL, ASCUS, and with normal cytology. DNA of U. parvum was demonstrated in majority of Mycoplasma IST2-positive cases, U. urealyticum DNA-only in 9 (4.9%). Predominance of 3/14 serovars of U. parvum was demonstrated. U. urealyticum biovar 2 was present more often in women with squamous intraepithelial lesions.

Clinical review of abnormal cervical cytology in pregnancy / 대한주산의학회잡지

PURPOSE: This study was performed to evaluate the clinical significance of abnormal cervical cytology in pregnancy and the effectiveness of cytologic and colposcopic surveillance of these women. METHODS: A retrospective analysis was conducted in pregnant women referred to the colposcopic clinic with abnormal cervical cytologic results above ASCUS between Jan. 2002 and Dec. 2007. The Initial colposcopy was performed at the end of 1st trimester. Cervical cytology and colposcopy were repeated once or twice during remaining period of pregnancy and at postpartum 6~8 weeks. Colposcopy directed cervical biopsies were taken in case of colposcopic abnormalities. Without evidence of invasion, no invasive procedure was attempted during pregnancy. Above CIN2 patients were treated postnatally. The postpartum diagnoses were compared to the worst antepartum impressions and initial cytologies. RESULTS: One hundred three pregnant women were referred to colposcopic clinic for 5 years. There was no invasive cervical cancer antenatally. After delivery, 53 patients were followed up and 17 patients above CIN2 lesions treated. Two microinvasive squamous cell carcinoma and 1 invasive adenocarcinoma were found postnatally. In 33 initial ASCUS cytologies, there were 7 CIN2,3 lesions and 3 invasive cancers. One CIN3 was found in 13 LSIL cytologies. All 7 HSIL patients had CIN3 lesions. There were 2 microinvasive cancers postnatally in 17 antenatal CIN2,3 patients. CONCLUSION: ASCUS cervical cytologic results in pregnancy have 30% possibility of CIN2,3 and cancer. LSIL results are normal in 85% and HSIL group 100% CIN3. Even though there is 12.5% risk of microinvasion in antenatal CIN2,3 lesions, noninvasive conservative management is reasonable.

Atipias escamosas de significado indeterminado: novas qualificações e importância na conduta clínica / Atypia in squamous cells of undetermined significance: news qualifications and importance in clinical conduct

O termo atipia escamosa de significado indeterminado (ASCUS) foi introduzido pelo Sistema de Bethesda em 1988, gerando diversas discussões a respeito do abuso deste diagnóstico e da conduta clínica mais apropriada a ser seguida. Após a introdução das novas qualificações das ASCUS (ASC-US e ASC-H), novas condutas foram preconizadas visando um tratamento mais objetivo em relação à lesão. O trabalho baseia-se na revisão da literatura para comparar dados e discutir a melhor conduta frente ao resultado de atipias escamosas. Dentre 62.323 colpocitologias realizadas em 2005 pelo laboratório em estudo, 197 casos (0,32%) corresponderamàs ASCUS. A porcentagem de retorno foi avaliada até junho de 2006, obtendo 53,3% de presença para a realização da citologia de repetição. O tempo gasto para repetir a colpocitologia variou entre 04 e 06 meses na maior parte (44,8%) dos retornos efetivados. A idade média das pacientes foi 47 anos, cujo seguimento mostrou maior número de lesões escamosas em mulheres com menos de 30 anos. Os dados obtidos através deste estudo se mostraram condizentes com a literatura, garantindo a boa qualidade dos exames realizados.No momento de decidir entre colposcopia, biópsia, repetição da colpocitologia e teste de hibridização para HPV no seguimento das ASCUS, deve-se considerar as subcategorias destas atipias, a fim de evitar o aparecimento de lesões mais graves.

The Usefulness of Concomitant High-Risk Human Papillomavirus Test and Colposcopy in Combination with the Papanicolaou Test in ASCUS Patients / 대한세포병리학회지

The objective of this study was to ascertain whether or not the high-risk human papillomavirus(HPV) test, when coupled with Papanicolaou(Pap) smears, would prove useful in the screening and management of patients in whom abnormal Pap smear results had been obtained. Concomitant high-risk HPV detection using the hybrid capture II test and colposcopy with a Pap smear were performed with 176 patients, all of whom had been screened for both cervical carcinoma and precancerous lesions. We concomitantly performed colposcopies on these patients. Upon the follow-ups, the histologic diagnoses of these patients were confirmed via either biopsy or hysterectomy. The rate of high-risk HPV detection was correlated with cytologic diagnoses and colposcopic findings. The group composed of the high-risk HPV-positive ASCUS patients exhibited a 55.7% rate of cervical intraepithelial neoplasia(CIN), a significantly higher rate than the 7.5% result obtained in the high-risk HPV- negative ASCUS group. HPV test showed high sensitivity(87%) and low specificity (62.6%) in detection of CIN and colposcopy also showed high sensitivity (88%) and low specificity(22%). Any combination of these tests improve sensitivity, but not specificity. High-risk HPV tests, when coupled with Pap smears, constituted a useful triage approach with regard to colposcopy-directed biopsies in patients in whom a cytologic diagnosis of ASCUS had been rendered.

Overexpression of p16(INK4A) as a biomarker for ASCUS in ThinPrep(TM) smear / 부인종양

OBJECTIVE: The overexpression of p16(INK4A) is induced by human papillomavirus (HPV) and associated with the carcinogenesis of cervical epithelia. So, immunostaining of p16(INK4A) may be useful biomarker in detecting CIN of cervix uteri in abnormal cervical lesions. The potential of p16(INK4A) as a biomarker for Atypical squamous cells of undetermined significance (ASCUS) examined in liquid-based specimens. METHODS: We collected samples 30 cases of ASCUS in Thinprep(TM) smears between March 2003 and August 2003. 23 control Thinprep(TM) cases were included; 10 negative for intraepithelial lesions, 13 cervical squamous intraepithelial lesions. p16(INK4A) immunochemial staining was performed on 53samples. At the same time, we tested another cervical swabs of patients by the Hybrid Capture II(TM) test. The cut off value was scored positive if it contained above 5 abnormal cells with nuclear and cytoplasmic immunostaining. RESULTS: The results of p16(INK4A) immunochemial staining comparing with one of HC II(TM) showed negative results with low kappa coefficient of 0.034. The sensitivity of p16(INK4A) immunochemial staining were 30.8% and the specificity were 82.4% respectively (p<0.01). p16(INK4A) is a useful marker for the detection of the cervical intraepithelial neoplasia but is not ASCUS. CONCLUSION: Immunostaining of p16(INK4A) is not useful triage test in detecting abnormal lesion of ASCUS in liquid-based specimens.

The efficacy of HPV DNA chip test in the atypical squamous cell of undetermined significance / 부인종양

OBJECTIVE: This study was performed to investigate the efficacy of DNA chip method for detecting and genotyping of human papillomavirus (HPV) and screening of high-grade CIN (cervical intraepithelial neoplasia) or invasive cancer in the patients with atypical squamous cells of undetermined significance (ASC-US). METHODS: This study was based on 131 cases to be revealed ASC-US by Pap smear for the cervical cancer screening from July 2004 to Octorber 2004. They were evaluated by HPV DNA chip test, Cervical colposcopy and directed biopsy, and cone biopsy. The results of type 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 54, 56, 58, 59, 66 and 68 in HPV DNA chip test were categorized as high risk HPV. We evaluate the detection rate of the high-grade CIN and invasive cancer by HPV DNA chip test. RESULTS: The incidence of high risk HPV DNA was 51.1% (67/131). Twelve of 131 (9.2%) were diagnosed as high-grade CIN or CIS on histology. The detection rate of high risk HPV DNA in high-grade CIN and invasive cancer was 83.3% (10/12). The detection rate of high risk HPV DNA was 36.0% (31/86) in normal or reactive, and 83.3% (10/12) in CIN II or above on histology. Higher the grade of biopsy, more the detection rate of high risk HPV DNA by HPV DNA chip test. CONCLUSION: The use of HPV DNA chip test in patients with ASC-US may be useful in detection of high-grade CIN or invasive cancer.

Correlación citohistológica de Papanicolaou Clase III (ASCUS) / Cytohistological Correlation of Pap Class III (ASCUS)

La anomalía en células epiteliales de significado incierto (ASCUS) abarca aquellas lesiones en células escamosas de origen inflamatorio o displásico, que no están bien definidas (sospechosas). El objetivo de nuestro trabajo fue determinar el porcentaje de citologías diagnosticadas como ASCUS que resultaron en cambios reactivos o lesiones intraepiteliales y evaluar la correlación con los hallazgos citólogicos e histopatológicos de estudios posteriores. Se analizaron 114 citologías cervicales (PAPs) diagnosticadas como ASCUS en el Servicio de Patología del H.I.G."Dr. José Penna". De este grupo sólo 60 pacientes fueron estudiadas con biopsias y citologías posteriores. El 70% (42/60) correspondieron a lesiones reactivas, seguidas en frecuencia por un 30% (18/60) de lesión intraepitelial de alto y bajo grado. Nosotros enfatizamos la importancia del estudio y seguimiento de todas las pacientes con diagnóstico de ASCUS ya que en un 30% de los casos se observó lesión intraepitelial con las consiguientes implicancias clínicas y pronósticas para las pacientes.

Atypical Squamous Cells of Undetermined Significance (ASCUS) comprise those lesions appearing in squamous cells that are not well defined (suspect lesions) of inflammatory or dysplastic origin. The purpose of this work is to determine the percentage of cytologies diagnosed as ASCUS that resulted in reactive changes or intraepithelial lesions and to relate it with cytologic and histopathologic findings in previous studies. 114 cervical cytologies (PAPs) diagnosed as ASCUS at the Pathology Unit of H.I.G. "Dr. José Penna" were assessed. Of this group, only 60 patients were later studied with biopsy and cytology procedures. 70% (42/60) corresponded to reactive lesions, followed in occurrence by 30% (18/60) of high and low degree intraepithelial lesions. We would like to emphasize the importance of the study and follow-up of all patients with ASCUS diagnosis, since we observed intraepithelial lesions in 30% of the cases, with the consequent clinical and prognostic implications for the patients.

Clinical Significance of HPV DNA Chip Test in the Management of Atypical Squamous Cells of Undetermined Significance / 대한산부인과학회잡지

OBJECTIVE: Cervical intraepithelial neoplasia (CIN) and invasive cervix cancer were detected in some cases of atypical squamous cells of undetermined significance (ASCUS) PAP smear. So it is reasonable to evaluate and manage ASCUS PAP smear. In this study, we attempted to assess the clinical significance of a cytologic diagnosis of ASCUS and determine the usefulness of HPV DNA chip test (which is a new diagnostic method for HPV) in management and evaluation of ASCUS patients. METHODS: This study was performed from November 2001 to June 2002 and included 48 cases of ASCUS. They were evaluated by HPV DNA chip test and the pathology was evaluated by punch biopsy, cone biopsy or hysterectomy. The result of type 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68 and 69 in HPV DNA chip test were categorized as high risk. RESULTS: The rate of CIN II or above in ASCUS was 18.8% (9/48). The detection rate of high risk HPV DNA in ASCUS was 41.7% (20/48). The detection rate of high risk HPV DNA was 30.6% (11/36) in normal or reactive, 33.3% (1/3) in CIN I, 80% (4/5) in CIN II, 100% (2/2) in CIN III, 100% (2/2) in invasive cervix cancer. Higher the grade of pathology, more the detection rate of high risk HPV DNA chip test. The sensitivity for the prediction of CIN II or above by HPV DNA chip test was 88.9% and specificity was 69.2%, respectively. CONCLUSION: The use of HPV DNA chip test in patients with ASCUS may provide usefulness in detection of CIN II, CIN III and invasive cervix cancer.
