    Full Text Available Background. Aneurysms of the extracranial vertebral artery are rare and can provide a diagnostic and therapeutic challenge. Methods. We reviewed the clinical history of a patient presenting with cervical radiculopathy, who harboured an extracranial vertebral artery aneurysm eroding the cervical spine. Results. CT Angiography and MR Angiography set the diagnosis, by revealing a left C5-C6 vertebral artery aneurysm with cervical root impingement. Bony reconstruction depicted enlargement of the C6 transverse foramen and a marked enlargement of the C6-C7 intravertebral foramen. The lesion was treated by intravascular proximal vertebral artery occlusion. Conclusions. Extracranial vertebral artery aneurysms require a high index of clinical suspicion. This is the first report of a vertebral artery pseudoaneurysm presenting with bony erosion, which supports a less minacious portrayal of vertebral artery aneurysms.

    Cervical myelopathy (CM) is mostly a degenerative process ending in myelopathic and/or radiculopathic syndromes. On T2-weighted magnetic resonance imaging (MRI), CM appears as a hyperintense area near the spondylotic spine. This high intensity signal depends on the impact of outer forces and their duration. It also determines the prognosis of the surgical candidate. A 40-year-old male patient admitted to our clinic with right upper extremity weakness and hypoesthesia that had started 2 months earlier. On neurological examination there was 2/5 motor weakness of right biceps brachii, and hypoesthesia over right C6 dermatome. Right upper extremity deep tendon reflexes were hypoactive, but lower ones were hyperactive. After clinical and radiological work-up, preliminary diagnosis was directed to a spinal intramedullary tumor. Total resection of the herniated cervical disc fragment and the mass lesion was managed. Pathology of the mass lesion was compatible with subacute infarct tissue and inflammatory response. Final diagnosis was CM under effect of cervical disc herniation. Contrast-enhanced spinal cord myelopathic lesions are very rare and resemble much more tumors and inflammatory processes. However, the principal treatment approach totally differs depending on pathology. When there are both a disc herniation and a high clinical suspicion; biopsy should be delayed. The most probable solution will be surgery for the disc disease with thorough preoperative scanning of vascular malformations; clinical and radiological close follow-up after surgery. Biopsy or surgical resection can be performed if patient deteriorates despite the primary surgery. PMID:25972718

    Full Text Available The experience of treatment for precancer and early cervical cancer by photodynamic therapy in 12 patients with primary diagnosis H-SIL (CIN II–III and cancer in situ is described. Chlo-rine photosensitizer Photolon was given intravenously at a dose of 0.75–1.15 mg/kg body weight. 2.5 h later the treatment with polyposition laser exposure (light dose – 150 J/cm2, light power density – 400–500 mW/cm2 was made. Thirty days later conization of the cervix with endocervical curettage assessing therapeutic response of cervical tumor tissue was per-formed. According to histological data complete response was in 4 patients, minute foci of CIN I were determined in 7 patients, 1 patient had foci of CIN II. 8 of 10 HPV-positive patients had complete eradication of HPV after treatment. There were no serious adverse events after light exposure. Marked therapeutic response, high anti-viral activity and good feasibility allow to consider photodynamic therapy as alternative organ-sparing treatment of early cancer and pre-cancer of cervix.

    An opera singer, who "made her living with her diaphragm", developed a post-traumatic unilateral radiculopathy due to cervical disc lesions, C3 to C6. During one year of severe neck and left arm pain she gradually lost the ability to sing difficult operatic passages which brought an end to her music career. Following a three level anterior cervical decompression and fusion, the neck and arm pain was immediately relieved. One week later her voice and singing ability returned to its full strength and power permitting her to resume her activities as a vocalist. The diagnosis of paresis of the left hemi-diaphragm as part of the cervical disc syndrome was implied by postoperative retrospective inference.

    Full Text Available Pap smear (Conventional smear is the most widely used cervical cancer screening test in the world. Negative intraepithelial lesion for malignancy, squamous intraepithelial lesion and cervical cancer remain important health problems for women worldwide. In developing countries like India, there is a great need for mass screening program for cervical lesion. AIMS AND OBJECTIVES To assess the clinician utility of The 2014 Bethesda System Reporting of cervical and vaginal epithelial abnormalities. MATERIAL AND METHODS All the cervical/vaginal cytology smears reported were retrieved and reviewed in the duration from 2007, 2008, 2009 and 2014. RESULTS A total number of 1700 cases of Pap smears were retrieved during period of study, out of which 90.0% were satisfactory for evaluation; 35.5% were within normal limit and 55.6% were NILM. A few (8.14% of the cases were reported as squamous intraepithelial lesion; 0.5% as atypical squamous cells and 0.19% were reported as atypical glandular cells. CONCLUSION Pap smear is a proven tested tool for making an early diagnosis and treating cervical cancer in early stage. Thus, Pap smear is simple, less expensive diagnostics tool suitable for implementation in India.

    Cervical cancer is one of the first causes of death in Mexican women population. The plasma proteome has a wide dynamic range concentrations of different protein and their alterations reflect the physiological state of the individual's health. The aim of this study was to characterize the 2D-PAGE serum patterns from healthy women and with different levels of cervical lesions. Changes in haptoglobin, apolipoproteins, and transthyretin, when comparing the serum from healthy women and serum from patients with different levels of cervical lesion were found. The Western blot analysis showed increasing concentrations of metalloproteinases (MMP's), proteins with important biological roles in tumor development and metastasis. Protein profiles in conjunction with MS, bioinformatics, and Western blot analysis, allow us to compile information for the acquisition of results to proposed candidates biomarkers of cervical cancer among Mexican women population.

    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

    Sialylated oligosaccharides of glycoproteins and glycolipids have been implicated in tumour progression and metastases. Altered expression of glycosidic antigens has been reported in cervical cancer. In cervix premalignant lesions, an increased expression of sialic acid has been reported. In the present study we determined the expression profiles of the glycosidic antigens Tn, sialyl Tn (sTn), Lewis a (Lea), sialyl Lewis a (sLea), Lewis x (Lex) and sialyl Lewis x (sLex) in cervical scrapes with cytological diagnoses of normal, low-grade squamous intraepithelial lesions (LGSIL) and high-grade squamous intraepithelial lesions (HGSIL). Cervical scrapings were collected to detect tumour antigens expressions by flow cytometry using monoclonal antibodies. Cytometry analysis of Tn, sTn, Lea and Lex did not reveal differences at the expression level among groups. The number of positive cells to sLea antigen increased in the HGSIL group with respect to the normal group (=0.0495). The number of positive cells to sLex antigen in the samples increased with respect to the grade of squamous intraepithelial lesion (SIL) ( < 0.001, Mann–Whitney U test). The intensity of expression of this antigen increased in the HGSIL samples with respect to normal samples ( < 0.0068). sLex antigen could be a candidate to be used as biomarker for the early diagnosis of cervical cancer.

    Full Text Available Cervical cancer is the second most common gynecological malignancy in the world. Human papilloma virus (HPV infection is the leading ethiologic agent in the development of premalignant and malignant cervical diseases. HPV is a member of the Papovaviridae family and until now over 100 types have been recognized. There are two types of viral infection: latent and productive. Virus induced oncogenesis is the result of interaction between virus oncoproteins E6 and E7 and tumor supresor host genes p53 and Rb. Many cofactors such as immunosuppression, early sexual relationship, multiple sexual partners, other sexualy transsmited infections and smooking are contributing factors of the precancerous and invasive cervical lesions. According to the oncogenic potential HPV are divided into three groups: low, intermediate and high oncogenic risk viruses. Molecular technics which are used for the virus detection are: In situ hibridisation,, Hybrid capture test and polymerasa chain reaction. Human papilloma virus testing has an important role in the follow up and treatment of women with 'atypical squamous cells of unknown significant' changes in cervical smears and low-grade squamous intraepithelial lesions, changes in punch biopsy.

    The metalloproteinases (MMP) 11 and 12 have been shown to be expressed in cervical cancer (CC). In order to extend our previous results, these MMPs were evaluated in cervical precursor lesions. One hundred seventeen cervical scrapes: thirty-six normal, thirty-six low grade squamous lesions (LSIL), thirty-six high grade (HSIL), nine CC; and, also ninety-nine paraffin-embedded cervical lesions: fifteen normal cervices, thirty eight LSIL, sixteen HSIL, and five CC were collected. The samples were analyzed for relative expression by real time RT-PCR or immunohistochemistry assay. We were able to identify a relative increased expression of MMP11 in 75% and 78% from LSIL and HSIL samples, respectively. While MMP12 expression was 64% and 75% in LSIL and HSIL, respectively. Positive samples for MMP11 expression were also positive for MMP12 expression and also increased according to illness progression. In the tissues, MMP11 or MMP12 expression was observed in the cytoplasm of the neoplastic cells, while in the normal epithelium was absent. The reaction was always stronger for MMP12 than MMP11. MMP11 expression was present in 77% and 66% of LSIL and HSIL, while MMP12 expression was 73% and 68%. There was a relationship between MMP11 or MMP12 expression and HPV infection. Our data are showing a relationship between diagnostic of precursor lesions and the MMP11 and 12 expressions, suggesting that their expression could be an early event in the neoplastic lesions of the cervix and could have clinical significance.

    OBJECTIVE To analyze the relation ship among vulva condyloma acuminatum, high-risk human papillomavirus (HPV) infections and cervical epithelium lesions.METHODS From May 2002 to April 2004 patients with vulva condyloma acuminatum were examined employing vulva biospy, colposcopy, highrisk HPV-DNA test and cervical bioscopy.RESUTS In 418 cases of vulva condyloma acuminatum, verified by pathologic analysis, high-risk HPV (+) infections were detected in 68.7% (287/418) of the cases. Among those patients, 20.6% (59/287) had concurrent subclinical cervical intraepithelial neoplastic (CIN) lesions. Among the high-risk HPV(-) 31.3 % (131), patients 7.6% (10/131) had concurrent subclinical CIN lesions. Pathological examination results: cervicitis,167 (40.0%); cervical HPV infection, 182 (43.5%); CIN-Ⅰ, 51(12.2%); CIN-Ⅱ, 16 (3.83%); CIN-Ⅲ, 2 (0.5%); cervical cancer, none. Another patient had vulva condyloma acuminatum with valva intraepithelial neoplasia (VIN) Ⅱ~Ⅲ.CONCLUSION It was concluded that simultaneous cervical HPV infection of many types was rather common in patients with vulva condyloma acuminatum. Vulva condyloma acuminatum is the chief clinical symptom which hints at a high possibility of infection with high-risk HPV. The patients are at high-risk for CIN and cervical cancer. We must pay more attention to the cervix in cases with vulva condyloma acuminatum.

    We aim to develop a CAD system for robust and reliable di erential diagnosis of breast lesions, in particular non-mass lesions. A necessary prerequisite for the development of a successful CAD system is the selection of the best subset of lesion descriptors. But an important methodological concern is whether the selected features are in uenced by the model employed rather than by the underlying characteristic distribution of descriptors for positive and negative cases. Another interesting question is how a particular classi er exploits the relationships between descriptors to increase the accuracy of the classi cation. In this work we set to: (1) Characterize kinetic, morphological and textural features among mass and non-mass lesions; (2) Examine feature spaces and compare selection of subset of features based on similarity of feature importance across feature rankings; (3) Compare two classi er performances namely binary Support Vector Machines (SVM) and Random Forest (RF) for the task of di erentiating between positive and negative cases when using binary classi cation for mass and non-mass lesions separately or when employing a multi-class classi cation. Breast MRI datasets consists of 243 (173 mass and 70 non-mass) lesions. Results show that RF variable importance used with RF-binary based classi cation optimized for mass and non-mass lesions separately o ers the best classi cation accuracy.

  1. Glass ionomer cements and their role in the restoration of non-carious cervical lesions

    Full Text Available Glass ionomer based materials are clinically popular in several areas of restorative dentistry, but restoration of cervical lesions has proven particularly successful. Various etiologies, conformations, locations and structural characteristics make non-carious cervical lesions more challenging to adhesive restorative procedures and marginal seal in the long run. Due to their characteristics, glass ionomer cements (GICs have precise indication for these cases. Moreover, the use of a GIC base underneath composite resin, the so-called "sandwich" or mixed technique, allows associating the good characteristics of composite resins and GICs, and has been considered quite useful in the restoration of non-carious cervical defects. The aim of this paper is to critically review the literature and discuss peculiar features of GICs regarding their role in the restoration of non-carious cervical lesions.

    Full Text Available Abstract Background Infection with human papillomavirus (HPV is associated with uterine cervical intraepithelial neoplasia (CIN and invasive cancers (ICC. Approximately 80% of ICC cases are diagnosed in under-developed countries. Vaccine development relies on knowledge of HPV genotypes characteristic of LSIL, HSIL and cancer; however, these genotypes remain poorly characterized in many African countries. To contribute to the characterization of HPV genotypes in Northeastern Tanzania, we recruited 215 women from the Reproductive Health Clinic at Kilimanjaro Christian Medical Centre. Cervical scrapes and biopsies were obtained for cytology and HPV DNA detection. Results 79 out of 215 (36.7% enrolled participants tested positive for HPV DNA, with a large proportion being multiple infections (74%. The prevalence of HPV infection increased with lesion grade (14% in controls, 67% in CIN1 cases and 88% in CIN2-3. Among ICC cases, 89% had detectable HPV. Overall, 31 HPV genotypes were detected; the three most common HPV genotypes among ICC were HPV16, 35 and 45. In addition to these genotypes, co-infection with HPV18, 31, 33, 52, 58, 68 and 82 was found in 91% of ICC. Among women with CIN2-3, HPV53, 58 and 84/83 were the most common. HPV35, 45, 53/58/59 were the most common among CIN1 cases. Conclusions In women with no evidence of cytological abnormalities, the most prevalent genotypes were HPV58 with HPV16, 35, 52, 66 and 73 occurring equally. Although numerical constraints limit inference, findings that 91% of ICC harbor only a small number of HPV genotypes suggests that prevention efforts including vaccine development or adjuvant screening should focus on these genotypes.

    The value of computed tomography in the spine and spinal cord disease recently has been well documented. However, little attention is made to the role of computed tomography in foramen magnum and high cervical cord lesion. We report 16 cases of the foramen magnum and high cervical cord lesion. Method: Either EMI Head Scanner, CT 1010 (slice thickness 10 mm) or EMI Whole Body Scanner, CT 5005 (slice thickness 13 mm) was used. In 9 cases enhanced CT with intravenous injection of contrast medium was performed. Eleven cases received intrathecal injection of metrizamide. Materials: 1) control group without cervical pathology 70 cases, 2) spinal cord tumor 6 cases, 3) atlanto-axial dislocation 6 cases, 4) Chiari malformation (type 1) 3 cases, 5) spinal foreign body (acupuncture needle) 1 case. Results: 1. plain CT. 1) In control group without cervical pathology the cervical cord at C/sub 1/ level was seen as area surrounded by ring of subarachnoid space. 2) In 14 cases except for 1 case of atlanto-axial dislocation and 1 case of spinal foreign body identification of the cervical cord at C/sub 1/ level was impossible. 3) CT was of diagnostic value in detecting altanto-axial dislocation and spinal foreign body. 2. enhanded CT. Meningioma and neurinoma showed positive contrast enhancement. However, astrocytoma and herniated cerebellar tonsils were not detectable. 3. CT metrizamide myelography visualized the subarachnoid space and made it possible to localize the lesion in the spinal canal in relation to the spinal cord. Conclusion: Attention should be given to plain CT finding at C/sub 1/ level in diagnosis of foramen magnum and high cervical cord lesion. If identification of cervical cord at C/sub 1/ level is impossible, it is suspected that subarachnoid space is blocked by the lesion, and enhanced CT and CT metrizamide myelography must be performed.

HR-HPV viral load (RLU/CO was determined by the Hybrid Capture Ⅱ (HCⅡ system, and they were categorized into five groups: 0-0.99, 1.00-9.99, 10.00-99.99, 100.00-999.99, ≥1000.00. The mean value and standard deviation of different HR-HPV viral load in the patients with cervicitis or with CIN Ⅰ, CINⅡ-Ⅲ, stage Ⅰ cervical cancer or stage Ⅱ cervical cancer were compared, and the correlation of HR-HPV viral load and pathogenesis of cervical lesions was analyzed. Results  HPV viral loads were significantly higher in CINⅠ(842.1±983.9, CINⅡ-Ⅲ (690.1±795.0, stage Ⅰ cervical cancer (893.1±974.2 and stage Ⅱ cervical cancer (699.5±908.3 patients than in cervicitis patients (274.2±613.6, P < 0.05, and the HPV viral loads in CINⅠ(842.1±983.9 and stage Ⅰ cervical cancer patients were higher than those in CINⅡ-Ⅲ patients (P < 0.05. When HR-HPV viral load was ≥100RLU/CO, the risk of CIN and cervical cancer increased with the increase in viral load, but there was no correlation between the viral load and pathological grades of cervical lesions. In the patients with stage ⅠB-Ⅱ cervical squamous cell carcinoma, when the HR-HPV viral load was ≥100RLU/CO, the risk of lymph node metastasis increased (P < 0.05, and the number of patients with maximum diameter of the cervical tumor ≥4cm also increased (P < 0.05. However, the HR-HPV viral load was not correlated with patient age, pathological type of the lesion, depth of cancer

    Only a small proportion of women infected with Human Papillomavirus (HPV) develop cervical cancer. Host immune response seems to play a role eliminating the viral infection and preventing progression to cancer. Characterization of tumor infiltrating lymphocytes (TILs) in cervical pre-neoplastic lesions and cervical cancer may be helpful to understand the mechanisms that mediate this protection. The aim of this study was to determine if there are differences in the localization and density (cells/mm(2)) of CD8+ T-cells, CD4+ T-cells and Tregs (CD25 + Foxp3+) in cervical pre-neoplastic lesions and cervical cancer. Immunohistochemical analysis of sections of 96 (26 CIN1, 21 CIN2, 25 CIN3, and 24 SCC) samples revealed that regardless of CIN grades, CD8+ T-cells are more abundant than CD4+, CD25+ and Foxp3+ cells in both the stroma and epithelium. There was a higher density of CD8+ cells in the stroma of cervical cancer compared to CIN3 (OR = 4.20, 95% CI 1.2-15), CIN2 (OR = 7.86, 95% CI 1.7-36.4) and CIN1 (OR = 4.25, 95% CI 1.1-17). Studies evaluating whether these cells are recruited before or after cancer progression will be helpful to understand the role of these cells in the natural history of HPV-induced lesions.

    Low-grade squamous intraepithelial lesions (LSIL) are frequently found during cervical cancer screening. Usually they are associated with a human papillomavirus (HPV) infection. Does the high-transmission rate of HPV infection to the male partner represent a clinical risk for him? Are preventive measures to be taken to prevent the occurrence of male diseases? More than 80% of all LSIL are associated with HPV infections. The prevalence of HPV infection in males can range up to 40%, with 60% of the male partners of LSIL female patients presenting with penile flat lesions. The spontaneous cure rate for male infections is very high (90% at 5 years) but negative consequences in females (cervical high-grade lesion and cervical cancer) are frequent. Their male counterparts are far rarer but in some patients can require deleterious treatment. Transmission prevention by the use of condoms and circumcision is discussed. The effectiveness of HPV vaccination in this situation has not been validated. PMID:20646823

    Full Text Available Introduction. High-risk human papilloma viruses play a main role in the development of cervical dysplasias and carcinomas. p16INK4a can be considered as a surrogate marker of active highrisk human papillomaviruses infection in dysplastic and neoplastic cells of the cervix. This study was aimed at determining the presence and level of p16INK4a expression in inflammatory, preneoplastic and neoplastic lesions of the cervix. Material and Methods. The study was performed on 109 samples of cervical biopsy. Cervical cancer was diagnosed in 36 patients, 34 patients had a preneoplastic change (dysplasia in stratified squamous cervix epithelium and a nonspecific inflammatory process was found in 39 patients. In all samples, immunohistochemical analysis using antibodies to p16INK4a was performed. Results. The expression of p16INK4a was verified in all cases of cervical cancer (100%, in 67.65% of dysplastic cervical lesions and in 38.5% of inflammatory lesions. A statistically highly significant difference was found in the presence and level of expression among neoplasic, dysplastic and inflammatory lesions of the cervix (χ² = 76.02, p < 0.001. The expression was more frequent and had a higher level in neoplastic and high grade dysplastic lesions compared to expression in inflammatory lesions and low grade dysplasias. Conclusion. The analysis of the presence of p16INK4a can differentiate non-neoplastic, high grade preneoplastic and neoplastic changes of the cervix. The use of p16INK4a in interpreting borderline lesions of the cervix can enable a rational therapeutic treatment of patients.

    OBJECTIVE To investigate the available parameters in gynecological screening for cervical lesions by liquid-based cytology technology (ThinPrep Cytology Test, TCT) and The Bethesda System (TBS), also with computer image analysis. METHODS With application of the image analysis system, all grades of cervical lesion cells were detected quantitatively and sorted in atypical squamous cells of undetermined significance (ASCUS), atypical squamous cells-cannot exclude HSIL (ASC-H), low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion (HSIL) and cervical squamous cell carcinoma (SCC) with the mean optical density (MOD), average grey (AG), positive units (PU), and nucleus to cytoplasmic ratio (N:C). Differences between each group of cells were compared and analyzed statistically.RESULTS Apart from four stereologic parameters in LSIL and HSIL groups there were no differences among them, in the other groups, there was statistically significant in differences between MOD, AG and PU values. Differences between them in the ratio of nucleus to cytoplasm were highly statistically signifi cant. CONCLUSION Stereological indexes may serve as a screening tool for cervical lesions. The image analysis system is expected to become a new means of cytological assisted diagnosis.

    Full Text Available Cervical cancer is one of most common cancers among women in the world caused by human papilloma virus infection. It develops in the tissue of cervix which connects upper body of the uterus to the vagina. The types of cancer are squamous cell carcinoma, adeno carcinoma and adeno squamous carcinoma based on location of cervix where cancer develops. In this paper, an automatic detection of squamous cell carcinoma in cervical images based on Discrete Wavelet Transform (DWT and K-Nearest Neighbor (KNN classifier is described. The energy features are extracted from DWT decomposed image of small area of cervical images. Then the features are fed into KNN classifier to classify whether the given area is normal or cancer affected region. The performance of the proposed system is evaluated by using three wavelets namely bi-orthogonal (bior3.7, Daubechies-8(db8 and Symlet (sym8. Experimental results show the performance of db8 with other wavelets that produces 97.22% average accuracy.

    Full Text Available A hundred-sixty paraffin-embedded specimens from female cervical lesions were examined for human papillomavirus (HPV types 6, 11, 16 and 18 infections by non-isotopic in situ hybridization. The data were compared with histologic diagnosis. Eighty-eight (55 biopsies contained HPV DNA sequences. In low grade cervical intraepithelial neoplasias (CIN I, HPV infection was detected in 78.7 of the cases, the benign HPV 6 was the most prevalent type. HPV DNA was detected in 58 of CIN II and CIN III cases and in 41.8 of squamous cell carcinomas (SCC. Histologically normal women presented 20 of HPV infection. Oncogenic HPV was found in 10 of these cases, what may indicate a higher risk of developing CINs and cancer. Twenty-five percent of the infected tissues contained mixed infections. HPV 16 was the most common type infecting the cervix and its prevalence raised significantly with the severity of the lesions, pointing its role in cancer pathogenesis. White women presented twice the cervical lesions of mulatto and African origin women, although HPV infection rates were nearly the same for the three groups (approximately 50. Our results showed that HPV typing by in situ hybridization is a useful tool for distinguishing between low and high risk cervical lesions. Further studies are required to elucidate risk factors associated with HPV infection and progression to malignancy in Brazilian population.

    Full Text Available Introduction. The restoration of non-carious cervical lesions is specific, mostly because of the location of their margins, especially the cervical margin, which is determined in cement and/or dentine. This feature makes the cervical margin more susceptible to micro-leak­age, causing marginal discoloration, postoperative sensitivity, development of the secondary caries and loss of the restoration. Material and methods. One of the criteria for inclusion of a patient in this study was the presence of at least two non-carious cervical lesions to be restored with the minimum depth of 1mm, independently of their location in the dental arch. A total of 60 restorations were placed in 30 patients, and every patient received both tested materials (composite resins and compomer on their non-carious cervical lesions. The clinical evaluation of the therapeutic success was performed six months and then one year after the day of the placement of restorations using the modified-United States Public Health Service criteria. The following was evaluated: retention, marginal integrity, marginal discoloration, wear, postoperative sensitivity and secondary caries. Results. A statistically significant high percent of restorations/teeth with postoperative sensitivity was found in the group of resin composite restorations after six months. At the end of the evaluation period, that is after one year, there were no statistically significant differences between materials for all evaluated criteria. Conclusion. The results of this study show the identical quality of both examined materials one year after the readjustment of non-carious cervical lesions.

    The purpose of our report is to describe a new application of kyphoplasty, the percutaneous anterolateral balloon kyphoplasty that we performed in two cases of metastatic osteolytic lesions in cervical spine. The first patient, aged 48 years, with primary malignancy in lungs had two metastatic lesions in C2 and C6 vertebrae. Patient's complaints were about pain and restriction of movements (due to the pain) in the cervical spine. The second patient, aged 70 years, with primary malignancy in stomach, had multiple metastatic lesions in thoracolumbar spine and C3, C4 and C5 vertebrae without neurological symptoms. The main symptoms were from cervical spine with severe pain even in bed rest and systematic use of opiate-base analgesic. The preoperative status was evaluated with X-rays, CT scan, MRI scan and with Karnofsky score and visual analogue pain (VAS) scale. Both patients underwent percutaneous anterolateral balloon kyphoplasty via the anterolateral approach in cervical spine under general anaesthesia. No clinical complications occurred during or after the procedure. Both patients experienced pain relief immediately after balloon kyphoplasty and during the following days. The stiffness also resolved rapidly and cervical collars were removed. VAS score significantly improved from 85 and 95 preoperatively to 30 in both patients. Karnofsky score showed also improvement from 40 and 30 preoperatively to 80 and 70, respectively, at the final follow-up (7 months after the procedure). Fluoroscopy-guided percutaneous anterolateral balloon kyphoplasty proved to be safe and effective minimally invasive procedure for metastatic osteolytic lesions of the cervical spine, reducing pain and avoiding vertebral collapse. Experience and attention are necessary in order to avoid complications.

    Small spinal cord lesions, even if clinically significant, can be due to the low sensitivity of some pulse sequences. We compared T2-weighted fast (FSE), and conventional (CSE) spin-echo and short-tau inversion-recovery (STIR)-FSE overlooked on MRI sequences to evaluate their sensitivity to and specificity for lesions of different types. We compared the three sequences in MRI of 57 patients with cervical spinal symptoms. The image sets were assessed by two of us individually for final diagnosis, lesion detectability and image quality. Both readers arrived at the same final diagnoses with all sequences, differentiating four groups of patients. Group 1 (30 patients, 53 %), with a final diagnosis of multiple sclerosis (MS). Demyelinating lesions were better seen on STIR-FSE images, on which the number of lesions was significantly higher than on FSE, while the FSE and CSE images showed approximately equal numbers of lesions; additional lesions were found in 9 patients. The contrast-to-noise ratio (CNR) of 17 demyelinating lesions was significantly higher on STIR-FSE images than with the other sequences. Group 2, 19 patients (33 %) with cervical pain, 15 of whom had disc protrusion or herniation: herniated discs were equally well delineated with all sequences, with better myelographic effect on FSE. In five patients with intrinsic spinal cord abnormalities, the conspicuity and demarcation of the lesions were similar with STIR-FSE and FSE. Group 3, 4 patients (7 %) with acute myelopathy of unknown aetiology. In two patients, STIR-FSE gave better demarcation of lesions and in one a questionable additional lesions. Group 4, 4 patients (7 %) with miscellaneous final diagnoses. STIR-FSE had high sensitivity to demyelinating lesions, can be considered quite specific and should be included in spinal MRI for assessment of suspected demyelinating disease. (orig.)

    Full Text Available Abstract Background Altered sialylation has been observed during oncogenic transformation. Sialylated oligosaccharides of glycoproteins and glycolipids have been implicated in tumor progression and metastases. In the cervical cancer high levels of sialic acid have been reported in the patients serum, and an increased of total sialic acid concentration has been reported for the cervical neoplasia and cervical cancer. This study investigates the changes in expression and distribution of α2,3-linked sialic acid and α2,6- linked sialic acid in low and high squamous intraepithelial lesions and in normal tissue. Methods Lectin histochemistry was used to examine the expression and distribution of sialic acid in different grades of cervical neoplasia. We applied Maackia amurensis lectin, which interacts with α2,3-linked sialic acid and Sambucus nigra lectin specific for α2,6-linked sialic acid. Results The histochemical analysis showed that α2,3-linked sialic acid and α2,6- linked sialic acid increased in intensity and distribution in concordance with the grade of squamous intraepithelial lesion (SIL. These results are in concordance with a previous study that reports increased RNAm levels of three sialyltransferases. Conclusions These results show that the change in sialylation occurs before cancer development and may play an important role in cellular transformation. These findings provide the basis for more detailed studies of the possible role of cell surface glycoconjugates bearing sialic acid in the cellular cervix transformation.

    Full Text Available Objective. To estimate the prevalence and genotypes of high-risk human papillomavirus (HPV focusing HPV 16, 18, 52, and 58 in Japan. Methods. Liquid-base cytology specimens were collected from Japanese women (n=11022, aged 14–98. After classifying cytodiagnosis, specimens were analyzed for HPV DNA by the multiplex polymerase chain reaction method, where 1195 specimens were positive for cervical smear, except adenomatous lesions. Result. HPV genotypes were detected in 9.5% of NILM and 72.2% of ASC-US or more cervical lesions. In positive cervical smears, HPV genotypes were HPV 52 at 26.6%, HPV 16 at 25.2%, HPV 58 at 21.8%, and HPV 18 at 7.1%. Most patients infected with HPV 16 were between 20–29 years old, decreasing with age thereafter. As for HPV 52 and 58, although the detection rate was high in 30- to 39-year-olds, it also was significant in the 50s and 60s age groups. Conclusion. In Japan, as a cause of abnormal cervical cytology, HPV52 and 58 are detected frequently in addition to HPV 16. In older age groups, HPV 52 and 58 detection rates were higher than that observed for HPV 16. After widespread current HPV vaccination, we still must be aware of HPV 52 and 58 infections.

    Mass-like renal lesions in children occur in a diverse spectrum of conditions including benign and malignant neoplasm, infection, infarction, lymphatic malformation, and traumatic injury. Although mass-like renal lesions can sometimes be suspected on plain radiographs and evaluated with US in children, subsequent CT is usually performed for the confirmation of diagnosis and further characterization. The purpose of this pictorial essay was to review the CT imaging findings of both common and uncommon mass-like renal lesions in pediatric patients. Understanding the characteristic CT appearance of mass-like renal lesions in children enables an accurate diagnosis and optimizes patient management. (orig.)

    Full Text Available Abstract Background Cervical carcinoma remains the second leading cause of cancer death in women worldwide and sexual behavior is regarded as the main contributing factor. We studied cervical cytology screening with surgical biopsy follow-up in women prisoners and compared the findings to those in the general population. Methods We reviewed 1024 conventional cervical smears, 73 cervical biopsies and 2 loop electrosurgical excision procedure (LEEP specimens referred to us from the Correctional Center in Columbus, Ohio during a 12-month period. The results were compared to 40,993 Pap smears from the general population for the same 12-month period. Results High grade squamous intraepithelial lesion (HGSIL was diagnosed in 1.3% of the cervical smears from the inmate population versus 0.6% in the general population (p < 0.01. The unsatisfactory rate was 1.6% compared to 0.3% in the general population (p < 0.01. Among the study population, follow-up tissue diagnosis was obtained in 24.3% of the abnormal cytology results (ASCUS, LGSIL, and HGSIL. Of the HGSIL Pap smears, 61.5% had a subsequent tissue diagnosis. Thirty-nine biopsies (52% of the all inmate biopsies and LEEP showed CIN II/III (cervical intraepithelial neoplasia II/III. Eight of these thirty-nine follow-up biopsies diagnosed as CIN II/III had a previous cervical cytology diagnosis of ASCUS. The average age for HGSIL was 30.5 years (S.D. = 5.7 and for low grade squamous intraepithelial lesion (LGSIL was 27.2 years (S.D. = 6.1. Conclusion A significantly higher prevalence of HGSIL cervical cytology and unsatisfactory smears was encountered in female inmates, with tissue follow-up performed in less than two thirds of the patients with HGSIL. These results are in keeping with data available in the literature suggesting that the inmate population is high-risk and may be subject to less screening and tissue follow-up than the general population. Clinicians should proceed with urgency to improve

The purpose of this study is to determine the most frequent HPV genotypes in Equatorial Guinea in order to develop future vaccination strategies to apply in this country. Methods A campaign against cervical cancer was carried out in the area on a total of 1,680 women. 26 of the women, following cytological screening, were treated surgically with a loop electrosurgical excision procedure (LEEP. Cases were studied histologically and were genotyped from paraffin blocks by applying a commercial kit that recognized 35 HPV types. Results Cytological diagnoses included 17 HSIL, 1 LSIL, 5 ASC-H and 3 AGUS. Histological diagnosis resulted in 3 cases of microinvasive squamous cell carcinoma stage IA of FIGO, 9 CIN-3, 8 CIN-2, 2 CIN-1, 3 flat condylomas and mild dysplasia of the endocervical epithelium. Fifteen of twenty-five cases genotyped were positive for HPV (60%. HPV 16 and 33 were identified in four cases each, HPV 58 in two other cases, and HPV 18, 31, 52, and 82 in one case, with one HPV 16 and 58 coinfection. Conclusion The frequency of HPV types in the African area varies in comparison to other regions, particularly in Europe and USA. Vaccination against the five most common HPV types (16, 33, 58, 18, and 31 should be considered in the geographic region of West Africa and specifically in Equatorial Guinea.

    Full Text Available ntroduction: Fetal neck masses are rare. In general, cystic hygroma is the most frequent form of fetal neck masses. It is essential to differentiate between different pathologies since this will affect prenatal counselling, antenatal and postnatal management. We aimed to present a case of cervical lymphangioma who was referred to our perinatology outpatient clinic with a diagnosis of an occipital encephalocele. Case Presentation: A 26-year-old nulliparous woman was referred to our perinatology clinic at 38 weeks’ gestation with an ultrasound diagnosis of occipital encephalocele so that postnatal surgery could be planned at our hospital. During obstetric ultrasonography examination, we identified a 4.7×4.5 cm, multiloculated cystic mass on the left lateral side of the fetal neck. The provisional diagnosis was lymphangioma. Fetal magnetic resonance (MR revealed a multiloculated cystic mass with smooth counters of 4.5×3.5×3.0 cm in size, originating from the soft tissues of the left side of the neck and it was not connected with the cervical spinal canal. The pathology report confirmed cervical lymphangioma. Conclusions: We would like to highlight the importance of differential diagnosis and follow up scans for any neck mass identified during scan to reach the final accurate diagnosis. This will enable that fetal neck masses could be diagnosed correctly in a more cautious manner.

    Full Text Available Change in the host and/or human papillomavirus (HPV DNA methylation profile is probably one of the main factors responsible for the malignant progression of cervical lesions to cancer. To investigate those changes we studied 173 cervical samples with different grades of cervical lesion, from normal to cervical cancer. The methylation status of nine cellular gene promoters, CCNA1, CDH1, C13ORF18, DAPK1, HIC1, RARβ2, hTERT1, hTERT2 and TWIST1, was investigated by Methylation Specific Polymerase Chain Reaction (MSP. The methylation of HPV18 L1-gene was also investigated by MSP, while the methylated cytosines within four regions, L1, 5'LCR, enhancer, and promoter of the HPV16 genome covering 19 CpG sites were evaluated by bisulfite sequencing. Statistically significant methylation biomarkers distinguishing between cervical precursor lesions from normal cervix were primarily C13ORF18 and secondly CCNA1, and those distinguishing cervical cancer from normal or cervical precursor lesions were CCNA1, C13ORF18, hTERT1, hTERT2 and TWIST1. In addition, the methylation analysis of individual CpG sites of the HPV16 genome in different sample groups, notably the 7455 and 7694 sites, proved to be more important than the overall methylation frequency. The majority of HPV18 positive samples contained both methylated and unmethylated L1 gene, and samples with L1-gene methylated forms alone had better prognosis when correlated with the host cell gene promoters' methylation profiles. In conclusion, both cellular and viral methylation biomarkers should be used for monitoring cervical lesion progression to prevent invasive cervical cancer.

The aim of this one-year prospective clinical study was to evaluate the treatment results of compomer restorations (Dyract® eXtra/ Dentsply/De Trey, Konstanz, Germany with a single step self-etching dental adhesive (Xeno® III Dentsply/De Trey, Konstanz, Germany used for restoring class V lesions (non-carious and primary carious cervical lesions. Material and Methods. A total number of 62 class V restorations (n = 62 were placed by one dentist in 30 patients on incisors, canines and premolars. The fillings were placed due to different indications: non-carious cervical defects (n = 32 and primary carious lesions (n = 30. The restorations were evaluated by a single-blind design, according to the Modified United States Public Health Service system 6 and 12 months following the placement. The following were evaluated: retention, marginal integrity, marginal discoloration, wear, postoperative sensitivity and secondary caries. The statistical analysis compared the ratings of each criteria between materials using the Pearson chi-square or Fisher’s exact test at a level of significance of 5% (p<0.05. Results. Two restorations of the non-carious lesion group were lost after 6 months, and after 12 months one restoration was lost in the group of primary carious lesions. There were no statistically significant differences between restorations for all evaluated criteria in both groups. Conclusion. The compomer restorations in combination with a single step self-etching dental adhesive showed acceptable clinical performance in Class V lesions after one year of clinical service.

    Human Papillomavirus (HPV) is the most common sexually transmitted infection worldwide and it is responsible for most cases of uterine cancer. In Ecuador there is limited information about HPV types (and variants) in cancerous lesions; however, identifying the type-specific HPV prevalence in cervical lesions of women living in Ecuador is important to better predict the impact of HPV prophylactic vaccination in this country. We studied the prevalence of HPV types in cervical cancerous or precancerous lesions from 164 Ecuadorian women and found that 86.0% were HPV positive. The most common types were HPV16 (41.8%) and HPV58 (30.5%). Interestingly, HPV18 was detected only in 2.8% of the HPV-positive samples. Fifteen DNA sequences (genes E6 and L1) from 16 samples positive for HPV16 belonged to the European lineage, considered one of the least carcinogenic lineages, and 1 (6.25%) to the Asian-American lineage. Similar analysis in 12 HPV58 positive samples showed that 10 (83.3%) sequences grouped in sublineage A2, which belongs to the oldest HPV58 lineage, 1 belonged to A3 and 1 to lineage C. This study suggests that the currently used HPV vaccines (bivalent and tetravalent) may have lower effectiveness in Ecuador than in other geographic locations where HPV18 is more prevalent.

    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 CONTEXT: Although head and neck masses are fairly common clinical presentation, it may be the only, or one of several nonspecific findings in serious illnesses like lymphoma or metastatic cancer. Thus, the need to efficiently differentiate patients with serious illness from those with self - limited disease arises. Fine Needle Aspiration Cytology (FNAC helps in the early and accurate diagnosis especially where approach for interventional biopsy is limited. AIMS: To diagnose various head and neck mass lesions via FNAC and correlating the results with clinical and histo pathological diagnosis. SETTINGS & DESIGN: The study was conducted in Shyam Shah Medical College and associated Sanjay Gandhi Memorial Hospital, Rewa ( MP, on 406 patients who presented with head and neck swellings . METHODS & MATERIAL: A complete general and systemic examination was carried out. FNAC was carried out on 406 subjects while biopsy was done for 123 lesions. The predictive value for FNAC was retrospectively correlated with biopsy results. RESULTS: In the current study, 372 diagnoses clinically correlated to 406 cytological diagnoses. The most common head and neck swellings were Cervical Lymph Node lesions (346 followed by Salivary Gland lesions(37, while the remaining 23 were other head and neck lesions. Out of the 123 biopsies performed, 111 were correctly diagnosed by FNAC itself. Inflammatory lesions ( 301 accounted for 86.99% of all cervical lymph node lesions. Demographic profile revealed a higher tendency of malignant lymph node lesions in Males (68.9% and in the older (>50years age group (55.6%; benign lesions were more common in the young (<20years [26.2%]. Similarly, Salivary Gland lesions ( 37 were mostly benign (32 and had a male predilection. 100% accuracy was achieved in the diagnosis of adenomas. Among other head and neck lesions, Lipomas were most common ( 30.4% achieving a cytological accuracy of 80%. Through this study, the Sensitivity ( 76

    Full Text Available Background: Cervical cancer is the second leading cause of cancer death among women. In this cancer, the effects of prevention, early diagnosis and treatment more than other cancers decrease the mortality rate. In 1970 human papilloma virus (HPV was introduction as major etiologic factor of cervical cancer. Different studies throughout the world revealed strong correlation between HPV and cancerous & precancerous changes in epithelial cells. Since cell culture and serological methods can not recognize the virus and its subtypes, the importance of the molecular methods including polymerase chain reaction (PCR in early and definite diagnosis of virus is obvious. Methods: In this study, after patient selection using the related protocol and completion of the questionnaires, 100 samples from cancer lesions of cervix selected. Then DNA extraction from paraffin blocks performed using standard method. Multiplex PCR with two pairs of primer (one as internal control performed and the PCR product run on 8% polyacrylamid gel. Results: The results showed that 73% of the tissues were infected by HPV. Conclusion: This finding confirm the previous results based of correlation between HPV,and cervical cancer.

    Full Text Available We analyzed the immunohistochemical pattern of epidermal growth factor receptor (EGFR in cervical squamous intraepithelial lesions (SILs in correlation with L1 HPV capsid protein, in order to determine the relationship between EGFR expression and the infection status of human papillomavirus (HPV. The study included 40 cases, 24 LSIL (low grade SIL (CIN1, cervical intraepithelial neoplasia and 16 HSIL (high grade SIL (6 cases of CIN2 and 10 cases of CIN3. The immunoexpression of L1 HPV protein was assessed on conventional cervico-vaginal smears and EGFR was immunohistochemically evaluated on the corresponding cervical biopsies. The HPV L1 capsid protein was expressed in 45.83% of LSIL and 25% of HSIL. EGFR was overexpressed in 62,4% of HSIL (58,4% CIN2 and 41,6% CIN3 and 37,6% LSIL. The immunoexpression of L1 HPV has clinical application in the progression assessment of the cervical precancerous lesions without a correlation to the grade of the cervical SIL. EGFR is expressed by all proliferating squamous epithelial cells, thus corresponding with the grade of SIL. The evaluation of EGFR status, correlated with L1 HPV protein expression, can provide useful data of progression risk of cervical squamous intraepithelial lesions

    Current diagnostic approaches for primary cervical cancer screening, work-up of equivocal or positive screening results or follow- up after treatment of precancerous lesions primarily rely on the morphologic interpretation of squamous epithelial cells (Pap cytology), in some setting accompanied by the detection of human papillomavirus DNA and have largely contributed to remarkable reduction of disease incidence in countries with implemented screening programs. However, these approaches are limited by a poor sensitivity and reproducibility of Pap cytology and low specificity for high grade cervical intraepithelial neoplasia of HPV DNA detection assays. Early detection might be improved by complementing or even replacing these tests by markers which are more directly related to molecular events triggering HPV-induced carcinogenesis and thereby might deliver more accurate diagnostic performance. The delineation of molecular changes which occur during different stages of HPV infections and the identification of changes which induce neoplastic alterations allow for the detection of markers that specifically highlight the transforming stage of the infection where viral oncogenes are overexpressed and therefore allow for a more specific diagnosis of lesions that require treatment. The evaluation of such markers in clinical studies revealed that some indeed show an improved diagnostic performance compared to Pap cytology or HPV DNA tests only.

    Full Text Available Background/Aim. Overexpression of p16INK4a has been found to be linked with genomic integration of high-risk human papillomavirus (HPV and the developement of precancerous cervical intraepithelial lesions. The aim of this study was to examine is there a higher positive level of correlation between grade of histological dysplasia and p16INK4a level of expression in cervical smear, compared to results of Papanicolaou test. We also examined the correlation between HPV type, p16INK4a expression and Papanicolau test results. Methods. A total of 48 women with precanceorous cervical lesions and HPV cervicitis and 10 healthy women were enrolled in the study. Papanicolaou test, CINtecTM p16INK4a citological immunohistochemical test, polymerase chain reaction (PCR HPV 16, 18, 31, 33 analysis and histopathology of the lesion were performed in all the patients. Results. Comparing the results of Papanicoulaou test and the grade of histological dysplasia, low-grade squamous intraepithelial lesion (LSIL was confirmed in 38%, and high-grade squamous intraepithelial lesion (HSIL in 69.2% of the patients (p > 0.05. Significant positive correlation was found between p16 overexpression and grade of histological dysplasia (p = 0.000. Overexpression p16 was found in 70% of LSIL and 94.4% of HSIL. Positive correlation was found between p16 overexpression and grade of dysplasia in Papanicolaou test (p = 0.011. In 38% of LSIL and 15% of HSIL cases p16 was not expressed. The most frequently found HPV type in PCR analysis was HPV16. Analysing the results of p16 test according to HPV status and Papanicolaou test rather heterogenous results were obtained. Conclusion. In the patients with precancerous cervical lesions a higher level of correlation was found between the grade of histological dysplasia and p16INK4a level of expression in the cervical smear, compared to the results of Papanicolaou test.

    Cervical cancer is a major public health problem in Morocco. The cervical cancer has a long precancerous period that provides an opportunity for the screening and treatment. Improving screening tests is a priority goal for the early diagnosis of cervical cancer. This study was conducted to evaluate the combination of p16INK4a protein expression, human papillomavirus (HPV) typing, and histopathology for the identification of cervical lesions with high risk to progress to cervical cancer among Moroccan women. A total of 96 cervical biopsies were included in this study. Signal amplification in situ hybridization with biotinylated probes was used to detect HPV. Immunohistochemistry was used to evaluate the expression of p16INK4a protein. HPV DNA was detected in 74.0% of the biopsies (71/96). Of the seventy-one positive HPV cases, we detected 67.6% (48/71) of high risk (HR)-HPV (HPV 16 and 18), 24% of low risk-HPV (HPV 6 and 11), 1.4% intermediate risk-HPV (HPV 31, 33, and 35), and 7% coinfections (HPV 6/11 and 16/18). Overexpression of p16INK4a protein was observed in 72.9% (70/96) of the biopsies. In addition, p16INK4a protein detection was closely correlated with recovery of HR HPV. Our result showed that p16INK4a expression level is correlated with HR-HPV status. PMID:27390742

    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.

    Objective In Mexico cervical cancer (CC) is the most common cause of death from neoplasia in women. Study aimed to analyze the current distribution of Human papillomavirus (HPV) types in women from Nayarit, Mexico, with Squamous intraepithelial lesions (SIL) and Cervical cancer (CC). Methodology Between January 2011 and July 2013, cervical samples were collected from female residents of the Mexican state of Nayarit and were analyzed by means of a LINEAR ARRAY® HPV genotyping test. Data analyses were performed using Stata ver. 8.0 statistical software. Results Of the samples analyzed, 91.2%, HPV DNA was detected. Of these positive samples, 82% were High-risk (HR) viral types. The most prevalent HPV genotypes identified were 16, 58, 31, 18, and 70. Forty two percent of participants had a single infection, while 23 and 26% of participants were infected with two or more HPV genotypes, respectively. HPV 16 was the most prevalent genotype identified and was frequently present as a co-infection with HPV types 18, 51, 52, 59, 66, or 70. Conclusion Women <20 years of age were most often infected with HPV, and the HPV Quadrivalent vaccine (types 16, 18, 6, and 11), currently available in Mexico, no confers protection against a subset of the HPV genotypes identified in the present study (58, 31, 70, and 35). Thus, it is important evaluate the geographical distribution of specific HPV genotypes in all health of center across Mexico in order to implement a successful vaccination program and to diagnose CC in its early stages.

    Full Text Available Fungal infections of the central nervous system (CNS are almost always a surprising finding. Their presentation is usually subtle, often without any diagnostic characteristics, and they are frequently mistaken for pyogenic abscesses, or brain tumors. Aspergillosis of the central nervous system is an uncommon infection, mainly occurring in immunocompromised patients. It may present in several forms, including meningitis, mycotic aneurysms, infarcts and a tumoral form. We report an intracranial granuloma due to Aspergillus fumigatus involving the anterior cranial fossa and the frontal lobe. The clinical symptoms began one year before admission. Final diagnosis was made after craniotomy. The patient was treated with an extensive excision of the cerebral mass and medical antifungal therapy (intravenous amphotericin B, but she failed to respond to these treatments and died.

    Full Text Available OBJECTIVES: Adhesive systems are continuously being introduced to Dentistry, unfortunately often without sufficient clinical validation. The aim of this study was to evaluate the clinical performance of cervical restorations done with three different adhesive systems. MATERIAL AND METHODS: 158 non-carious cervical lesions of 23 patients were restored with a nanofilled composite resin (Filtek Supreme, 3M/ESPE combined with Single Bond (3M/ESPE, group SI, Clearfil SE (Kuraray Medical Inc., group CL and Xeno III (De Trey Dentsply, group XE. In groups SI-B, CL-B and XE-B, the outer surface of the sclerotic dentin was removed by roughening with a diamond bur before application of the respective adhesive systems. In groups CL-BP and XE-BP, after removal of the outer surface of the sclerotic dentin with the bur, the remaining dentin was etched with 37% phosphoric acid and the self-etch adhesive systems Clearfil SE and Xeno III were applied, respectively. Lesions were evaluated at baseline, and restorations after 3 months, 1 year and 2 years using modified USPHS criteria. RESULTS: After 2 years, no significant difference was found between the retention rates of the groups (p >0.05. Although groups CL and SI showed significantly better marginal adaptation than group XE (p0.05. After 2 years no significant difference was observed among the marginal staining results of all groups (p>0.05. CONCLUSION: Although all adhesive systems showed similar retention rates, Clearfil SE and Single Bond showed better marginal adaptation than Xeno III after 2 years of follow-up.

    To determine human papillomavirus (HPV) types distribution in cervical lesions in a Southern Italian female population in Messina and their relationship between HPV type and grade of colposcopic and histopathological abnormality, a total of 253 women aged 17-68 years, with previous cytological abnormalities, were included in this study. HPV-DNA testing, colposcopy and biopsy were performed. For each sample, cervical cells were collected by centrifugation and DNA was extracted, followed by a PCR-based HPV-DNA assay and reverse dot blot genotyping. HPV-16 was found the most common type (46.6 %) followed by HPV-31 (26.9 %), -6 (18.6 %), -58 (8.8 %), -18 (6.7 %), -66 (5.7 %), -52 and -53 (4.7 %). Out of 62 women with abnormal transformation zone (ATZ) area compatible with squamous intraepithelial lesion (SIL) or cervical cancer (CC), 64.5 % was found high risk (HR) HPV-positive. Moreover the severity of the colposcopic diagnosis was positively correlated with the higher HPV oncogenicity risk (HPV-16 P = 0.023; and HPV-53 P = 0.047). The HPV-16 was found the most prevalent type within each histological category: 66.7 %, 31.2 %, 44 % and 37.2 % of CC, high grade (H)SIL, low grade (L)SIL and chronic cervicitis respectively; followed by HPV-31 present in 25 %, 8 %, and 13.3 % of HSIL, LSIL and chronic cervicitis respectively. A higher HPV incidence than the rest of Italy was found, in agreement with that detected by other authors for the South of the country. These data provide further information about the types prevalence in women with cervical lesions living in Eastern Sicily, suggesting the introduction of new targeted vaccines against a wider spectrum of HPV.

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.

    Full Text Available Abstract Background Fine needle aspiration (FNA biopsy has been rarely used in oral and oropharyngeal lesions. The goal of this study was to assess the value and accuracy of FNA biopsy in the diagnosis of oral and oropharyngeal lesions particularly in regards to discriminating benign from malignant tumors. Methods Sixteen cases of FNA biopsies obtained of various intraoral and oropharyngeal masses or lesions performed at our institution during the eight-year period from 1998 to 2006 were retrospectively reviewed. The aspiration cytologic diagnoses were correlated with the histologic examination of the corresponding resected lesions. Results Sixteen cases of intraoral lesions evaluated by FNA biopsies during the period of 1998–2006 were reviewed. The sites of involvement were: lip 1, maxillary sinus 3, pharynx/oropharynx 5, floor of mouth 4, buccal mucosa 2 and peritonsillar area 1. Patients' age ranged from 30 to 87 with an average of 54 years. Male to female ratio was 1:3. Cytologically, 7 cases were diagnosed as suspicious/malignant, and 9 cases as benign (including 6 benign neoplasm, 1 atypical, and 2 reactive or "descriptive". Fifteen cases had corresponding surgical resection for histologic examination, of these, 9 cases were interpreted as malignant, and 6 as benign. There were no false positive diagnoses of malignancy on FNA. Two cases were interpreted as benign or atypical cytologically, but were found to be malignant on histologic examination. Conclusion FNA biopsy of intraoral and oropharyngeal masses is a valuable procedure for the initial evaluation of various lesions. It provides helpful information about these lesions and avoids hasty or unnecessary surgical biopsy. It is a rapid and relatively noninvasive procedure. Furthermore, aspiration biopsy is an important tool in the diagnosis and management of these lesions, both neoplastic and non-neoplastic, and can be sometimes complemented by ancillary studies for more accurate

    Enhanced expression of the HPV 16 E6-E7 oncogenes may trigger neoplastic transformation of the squamous epithelial cells at the uterine cervix. The HPV E2 protein is a key transcriptional regulator of the E6-E7 genes. It binds to four E2 binding sites (E2BSs 1-4) in the viral upstream regulatory region (URR). Modification of E2 functions, for example, by methylation of E2BSs is hypothesized to trigger enhanced expression of the viral E6-E7 oncogenes. In the majority of HPV-transformed premalignant lesions and about half of cervical carcinomas HPV genomes persist in an extra-chromosomal, episomal state, whereas they are integrated into host cells chromosomes in the remaining lesions. Here we compared the methylation profile of E2BSs 1-4 of the HPV 16 URR in a series of 18 HPV16-positive premalignant lesions and 33 invasive cervical cancers. CpGs within the E2BSs 1, 3, and 4 were higher methylated in all lesions with only episomal HPV16 genomes compared with lesions displaying single integrated copies. Samples with multiple HPV16 integrated copies displayed high methylation levels for all CpGs suggesting that the majority of multiple copies were silenced by extensive methylation. These data support the hypothesis that differential methylation of the E2BSs 1, 3 and 4 is related to the activation of viral oncogene expression in cervical lesions as long as the viral genome remains in the episomal state. Once the virus becomes integrated into host cell chromosomes these methylation patterns may be substantially altered due to complex epigenetic changes of integrated HPV genomes.

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

    VEGF and podoplanin (PDPN) have been identified as angiogenesis and/or lymphangiogenesis regulators and might be essential to restrict tumor growth, progression, and metastasis. In the present study, we evaluate the association between the expression of these markers and CIN grade. Immunohistochemistry was performed in 234 uterine cervical samples using conventional histologic sections or TMA with the monoclonal antibodies to VEGF (C-1 clone) and podoplanin (D2-40 clone). Positive-staining rates of VEGF in 191 CIN specimens were significantly associated with histological grade (P < 0.001). Negative and/or focal immunostaining for PDPN were more frequent in CIN 3 (P = 0.016). We found that patients with CIN 3 more frequently had strong and more diffuse staining for VEGF and diminished staining for PDPN (P = 0.018). Strong and more diffuse VEGF immunoexpressions in CIN 2 and CIN 3 were detected when compared to CIN 1. Negative and/or focal PDPN immunoexpression appear to be more frequent in CIN 3. Moderate to strong VEGF expression may be a tendency among patients with high-grade lesions and diminished PDPN expression. PMID:27313335

    Polymorphisms in chemokine receptors play an important role in the progression of cervical intraepithelial neoplasia (CIN) to cervical cancer (CC). Our study examined the association of CCR2-64I (rs1799864) andCCR5-Δ32 (rs333) polymorphisms with susceptibility to develop cervical lesion (CIN and CC) in a Brazilian population. The genotyping of 139 women with cervical lesions and 151 women without cervical lesions for the CCR2-64I and CCR5-Δ32 polymorphisms were performed using polymerase chain reaction-restriction fragment length polymorphism. The individuals carrying heterozygous or homozygous genotypes (GA+AA) for CCR2-64I polymorphisms seem to be at lower risk for cervical lesion [odds ratio (OR) = 0.37, p = 0.0008)]. The same was observed for the A allele (OR = 0.39, p = 0.0002), while no association was detected (p > 0.05) with CCR5-Δ32 polymorphism. Regarding the human papillomavirus (HPV) type, patients carrying the CCR2-64Ipolymorphism were protected against infection by HPV type 16 (OR = 0.35, p = 0.0184). In summary, our study showed a protective effect ofCCR2-64I rs1799864 polymorphism against the development of cervical lesions (CIN and CC) and in the susceptibility of HPV 16 infection.

    Background: Cervical cancer is essentially a sexually transmitted disease related to human papillomavirus infection. This disease’s incidence has been globally enhanced, particularly in increasingly younger women. Objective: To determine cervical lesions in women younger than 25 years. Methods: An observational, descriptive and correlational study including 248 patients registered at the Pathological Anatomy Service of the General University Hospital Dr. Gustavo Aldereguía Lima of Cienfuegos was conducted from January to December 2007. It also included the first quarter of 2008. The following variables were analyzed: patient’s age, age at first intercourse, number of sexual partners, type and degree of injury, and reason for attending consultation. Results: Women over 21 years old and those who had had 2 and 3 sexual partners predominated. The main reason for attending consultation was cervicitis (84, 7%. In 22.6% of women grade I intraepithelial neoplasia was detected, while grade II and III were detected in 41, 9% and 33, 1%, respectively. In 90% of younger patients the lesion was malignant. Conclusions: The presence of cervical lesions in women under 25 years is not low and neither is the frequency of malignant lesions.

    Full Text Available BACKGROUND: HPV typing using formalin fixed paraffin embedded (FFPE cervical tissue is used to evaluate HPV vaccine impact, but DNA yield and quality in FFPE specimens can negatively affect test results. This study aimed to evaluate 2 commercial assays for HPV detection and typing using FFPE cervical specimens. METHODS: Four large North Carolina pathology laboratories provided FFPE specimens from 299 women ages18 and older diagnosed with cervical disease from 2001 to 2006. For each woman, one diagnostic block was selected and unstained serial sections were prepared for DNA typing. Extracts from samples with residual lesion were used to detect and type HPV using parallel and serial testing algorithms with the Linear Array and LiPA HPV genotyping assays. FINDINGS: LA and LiPA concordance was 0.61 for detecting any high-risk (HR and 0.20 for detecting any low-risk (LR types, with significant differences in marginal proportions for HPV16, 51, 52, and any HR types. Discordant results were most often LiPA-positive, LA-negative. The parallel algorithm yielded the highest prevalence of any HPV type (95.7%. HR type prevalence was similar using parallel (93.1% and serial (92.1% approaches. HPV16, 33, and 52 prevalence was slightly lower using the serial algorithm, but the median number of HR types per woman (1 did not differ by algorithm. Using the serial algorithm, HPV DNA was detected in >85% of invasive and >95% of pre-invasive lesions. The most common type was HPV16, followed by 52, 18, 31, 33, and 35; HPV16/18 was detected in 56.5% of specimens. Multiple HPV types were more common in lower grade lesions. CONCLUSIONS: We developed an efficient algorithm for testing and reporting results of two commercial assays for HPV detection and typing in FFPE specimens, and describe HPV type distribution in pre-invasive and invasive cervical lesions in a state-based sample prior to HPV vaccine introduction.

    Gene promoter methylation may be used a potential biomarker for detecting solid tumor including cervical cancer. Here, we used methylation sensitive-high resolution melting (MS-HRM) analysis to detecting promoter methylation ratios of DAPK1, MGMT and RARB gene in patients with different cervical disease grade. The detection of gene promoter methylation was conducted in two hundred fifty patients’ samples including normal cytology (n=48), cervical intraepithelial neoplasia grade 1 (CIN1, n=54), cervical intraepithelial neoplasia grade 2 (CIN2, n=47), cervical intraepithelial neoplasia grade 3 (CIN3, n=56) and cervical squamous cell carcinomas (SCS, n=45). We found there were a significant positive correlation between the promoter methylation status of DAPK1 and cervical disease grade (P=0.022). In addition, the methylated promoters of DAPK1 combined with MGMT, MGMT combined with RARB, DAPK1 combined with RARB were positive correlated with cervical disease grade (P < 0.05). All three genes promoters methylated were positive correlated with cervical disease grade (P < 0.001). Receiver operating characteristic (ROC) curves was conducted to evaluate whether the three genes methylation could be used to be a potential marker for diagnosing high grade cervical disease (HSIL and SCC). The cutoff values for the methylation rates of all these genes were 0-5%. Regrettably, only the methylation of MGMT combined with DAPK1 gave 43.4% sensitivity and 68.6% specificity. The current results indicated that MS-HRM-based testing for DNA methylations of MGMT plus DAPK1 genes holds some promise for high grade cervical disease screening. PMID:26823825

    The aim of this study was to evaluate the 6- and 12-month clinical performance of four adhesion strategies from the same manufacturer (Kerr) in non-carious cervical lesions (NCCLs) using two evaluation criteria. Thirty-five patients, with at least four NCCLs each, participated in this study. After samplesize calculation, 180 restorations were assigned to one of the following groups: OFL (Optibond FL), OSP (Optibond Solo Plus), XTR (Optibond XTR), and AIO (Optibond All-In-One). The composite resin Filtek Supreme Ultra (3M ESPE) was placed incrementally. The restorations were evaluated at baseline, after 6 months, and after 12 months, using both the FDI and the USPHS-modified criteria. Statistical analyses were performed with Friedman repeated measures, ANOVA by rank, and the McNemar test for significance in each pair (α=0.05). Six restorations (2 for OFL, 1 for OSP, 2 for XTR, and 1 for AIO) were lost at 12 months (P>0.05 for both evaluation criteria). Marginal staining was observed in seven restorations using the FDI criteria (P>0.05) and three restorations using the USPHSmodified criteria (P>0.05). Eight restorations (2 for OSP, 3 for XTR, and 3 for AIO) were classified as Bravo for marginal adaptation using the USPHSmodified criteria (P>0.05). However, 62 restorations (14 for OFL, 12 for OSP, 15 for XTR, and 21 for AIO) were classified as Bravo using the FDI criteria (P>0.05). The four adhesion strategies showed similar clinical retention at 6 and 12 months. The FDI evaluation criteria tend to be more sensitive than the USPHS-modified criteria. PMID:25625130

    A number of 66 specimens from female cervical lesions were examined for infection with human papillomavirus (HPV) types 6, 11, 16, and 18 by nucleic acid hybridization in dot-blot techniques and 35 sera were tested by the immunodot-blot technique, in order to detect the presence of anti E4 and E7 HPV protein antibodies. The findings were compared with the histologic diagnosis. Fifty-six per cent of specimens contained HPV DNA sequences. In 47% of specimens from cervical carcinoma, HPV 11 was detected in 4 cases, HPV 16 in 21 cases, and HPV 18 in 7 cases. Serum antibodies against HPV 16 E4 and HPV 16 E7 occurred in all the cases of uterine carcinoma, in 4 of 10 cases of CIN I-II, and in 3 of 5 sera obtained from apparently healthy women. The analysis of risk factors disclosed the early onset of sexual activity, a relatively high number of births and abortions before the age of 22 years, the use of oral oestroprogestative contraceptive agents, the presence in anamnesis of genital infections with bacterial flora--Candida albicans, Trichomonas vaginalis, Chlamydia trachomatis, Mycoplasma, etc. Our results showed that HPV typing by nucleic acid hybridization was useful for differentiating low- from high-risk cervical lesions and also tried to elucidate the risk factors associated with HPV infections and progression to malignancy.

    Abnormal expression and promoter methylation of microRNAs (miRNAs) are common events during cervical carcinogenesis. Worldwide, infection by types 18 and 16 of human papillomaviruses (HPVs) is considered the major risk factor for cervical cancer development. It has been reported that expression of the miRNAs can be deregulated by specific HPV genotypes. In this study we analyzed the promoter methylation of 22 miRNAs and the expression of three miRNAs in 10 non-squamous intraepithelial lesions (Non-SIL) without HPV16 infection, and 7 Non-SIL, 16 low-grade SIL (LSIL) and 16 cervical cancer samples, all with HPV16 infection. The methylation status was determined using Human Cancer miRNA EpiTect Methyl II Signature PCR Array® and the expression of miR-124, miR-218 and miR-193b was determined by qRT-PCR using individual TaqMan assays. Comparisons of groups defined were performed using the Fisher exact test for categorical variables and Mann-Whitney test for continuous variables. A p-value of <0.05 was considered statistically significant. The methylation levels of miR-124-2, miR-218-1, miR-218-2 and miR-34b/c promoters were significantly higher in cervical cancer than in LSIL samples. The methylation levels of miR-193b promoter were significantly lower in cervical cancer than in LSIL samples. The expression of miR-124 and miR-218 was significantly lower in cervical cancer than in LSIL samples. The expression of miR-193b was significantly higher in cervical cancer than in LSIL and Non-SIL samples. Our results suggest that the abnormal promoter methylation and expression of miR-124, miR-218 and miR-193b are common events during cervical carcinogenesis. PMID:26797462

    Human papillomavirus (HPV) types 16/18, included in HPV vaccines, contribute to the majority of cervical cancer, and a substantial proportion of cervical intraepithelial neoplasia (CIN) grades 2/3 or worse (CIN2+/CIN3+) including adenocarcinoma in situ or worse. The aim of this study was to quantify the effect of quadrivalent HPV (qHPV) vaccination on incidence of CIN2+ and CIN3+. A nationwide cohort of girls and young women resident in Sweden 2006-2013 and aged 13-29 (n = 1,333,691) was followed for vaccination and histologically confirmed high-grade cervical lesions. Data were collected using the Swedish nationwide healthcare registers. Poisson regression was used to calculate incidence rate ratios (IRRs) and vaccine effectiveness [(1-IRR)x100%] comparing fully vaccinated with unvaccinated individuals. IRRs were adjusted for attained age and parental education, and stratified on vaccination initiation age. Effectiveness against CIN2+ was 75% (IRR = 0.25, 95%CI = 0.18-0.35) for those initiating vaccination before age 17, and 46% (IRR = 0.54, 95%CI = 0.46-0.64) and 22% (IRR = 0.78, 95%CI = 0.65-0.93) for those initiating vaccination at ages 17-19, and at ages 20-29, respectively. Vaccine effectiveness against CIN3+ was similar to vaccine effectiveness against CIN2+. Results were robust for both women participating to the organized screening program and for women at prescreening ages. We show high effectiveness of qHPV vaccination on CIN2+ and CIN3+ lesions, with greater effectiveness observed in girls younger at vaccination initiation. Continued monitoring of impact of HPV vaccination in the population is needed in order to evaluate both long-term vaccine effectiveness and to evaluate whether the vaccination program achieves anticipated effects in prevention of invasive cervical cancer.

    We assessed the prevalence and risk factors for development of non-carious cervical lesions (NCCLs) in children attending special needs schools in India. The participants were 395 children aged 12-15 years with disabilities in learning, communication, physical function, and/or development. A questionnaire was designed in order to collect information on sociodemographic characteristics, oral hygiene practices, dietary habits, and risk factors for NCCLs. The chi-square test, bivariate analysis, and logistic regression analysis were used to analyze the data. Presence of NCCLs was associated with use of toothpowder or other materials for teeth cleaning, use of harder toothbrushes, use of a horizontal scrub technique for toothbrushing, consumption of a vegetarian diet, and greater consumption of lemon. The overall prevalence of NCCLs was 22.7%. Most lesions involved minimal loss of contour or defects health care among children attending special needs schools. PMID:25807907

  17. Diagnostic usefulness of FDG PET for pancreatic mass lesions

    International Nuclear Information System (INIS)

    The purpose of this study was to investigate the feasibility of [18F]2-deoxy-2-fluoro-D-glucose (FDG) positron emission tomography (PET) in patients with a pancreatic mass by comparing the results with those of X-ray computed tomography (CT) and magnetic resonance (MR) imaging. Eighty-six patients with pancreatic lesions, included 65 malignant tumors and 21 benign masses (55 masses were proven histologically and the others were diagnosed clinically), were studied. The diagnostic factors of CT and MR imaging were evaluated, and those of FDG PET were also evaluated for malignant and benign masses by visual interpretation and quantitative interpretation with the standardized uptake value (SUV) and SUVgluc which was designed to reduce the effects of a high blood sugar level. Visual interpretations were evaluated only in FDG PET images, and quantitative interpretations were evaluated by referring to CT and/or MR imaging. The correlation between SUV and the degree of histological differentiation in pancreatic ductal adenocarcinoma was investigated. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy for CT imaging were 91, 62, 88, 68 and 84%, and for MR imaging 78, 70, 88, 54 and 76%, respectively. In visual interpretation of FDG PET images, the sensitivity, specificity, PPV, NPV and accuracy were 82, 81, 93, 59 and 81%, respectively. Significant differences between malignant and benign lesions existed in SUV and SUVgluc (p<0.0001, each). With the cutoff value of SUV as 2.1 and SUVgluc as 2.2, the accuracy of diagnosis was maximal. With that cutoff value, the sensitivity, specificity, PPV, NPV and accuracy for SUV were 89, 76, 92, 70 and 86%, and for SUVgluc 91, 76, 92, 73 and 87%, respectively. The sensitivity and NPV of SUVgluc were higher than those of SUV, which suggests that SUVgluc may be more useful in reducing the number of overlooked malignant tumors. The specificity and PPV of FDG PET were superior to those of

    The overal survival of patients with cervical cancer has improved due to detection at an early stage and availability of comprehensive treatments in China. As patients’ lives prolonged, it is important to understand their health-related quality of life (QoL) during and after treatment. We used the EQ-5D questionnaire to assess QoL of 194 patients with cervical lesions at Sichuan University West China Second Hospital between May 2010 and January 2011. Patients were surveyed before primary treatment and at 1, 3, and 6 months after primary treatment. Results showed a consistent decline in EQ-5D scores in the spectrum of cervical lesions at each time point after treatment (alP < 0.05). For patients with precursor lesions, there was an increasing trend along the timeline of treatment (P < 0.01). For patients with early-stage cervical cancer, EQ-5D scores declined in the first month (P = 0.01) and gradualy increased to higher levels at 6 months post-treatment than those before treatment (P < 0.01). EQ-5D scores followed a similar trend in patients with advanced cervical cancer (P = 0.04), though they did not statisticaly rebound after 6 months (0.84± 0.19 vs. 0.86± 0.11,P = 0.62). Regarding advanced cervical cancer, EQ-5D scores for women above 40 years of age appeared to recover more rapidly and reached higher levels than those for women below 40 years (P = 0.03). Caution and extra care are recommended in the early period of cervical cancer treatment given the slight deterioration in the QoL, and in particular, for younger cervical cancer patients. Our study implies that health care providers may need to improve the health-related QoL of cervical cancer patients.

    Two classes of Human papillomaviruses (HPV) infect the anogenital track: high risk viruses that are associated with risk of cervical cancer and low risk types that drive development of benign lesions, such as condylomas. In the present study, we established quantitative transcriptional maps of the viral genome in clinical lesions associated with high risk HPV16 or low risk HPV6b. Marked qualitative and quantitative changes in the HPV16 transcriptome were associated with progression from low to high grade lesions. Specific transcripts encoding essential regulatory proteins such as E7, E2, E1^E4 and E5 were identified. We also identified intrinsic differences between the HPV6b-associated condyloma transcript map and that of the HPV16-associated low grade CIN specifically regarding promoter usage. Characterization and quantification of HPV transcripts in patient samples thus establish the impact of viral transcriptional regulation on the status of HPV-associated lesions and may therefore help in defining new biologically-relevant prognosis markers.

    Full Text Available Abstract Background Persistent high risk HPV infection can lead to cervical cancer, the second most common malignant tumor in women worldwide. NK cells play a crucial role against tumors and virus-infected cells through a fine balance between activating and inhibitory receptors. Expression of triggering receptors NKp30, NKp44, NKp46 and NKG2D on NK cells correlates with cytolytic activity against tumor cells, but these receptors have not been studied in cervical cancer and precursor lesions. The aim of the present work was to study NKp30, NKp46, NKG2D, NKp80 and 2B4 expression in NK cells from patients with cervical cancer and precursor lesions, in the context of HPV infection. Methods NKp30, NKp46, NKG2D, NKp80 and 2B4 expression was analyzed by flow cytometry on NK cells from 59 patients with cervical cancer and squamous intraepithelial lesions. NK cell cytotoxicity was evaluated in a 4 hour CFSE/7-AAD flow cytometry assay. HPV types were identified by PCR assays. Results We report here for the first time that NK cell-activating receptors NKp30 and NKp46 are significantly down-regulated in cervical cancer and high grade squamous intraepithelial lesion (HGSIL patients. NCRs down-regulation correlated with low cytolytic activity, HPV-16 infection and clinical stage. NKG2D was also down-regulated in cervical cancer patients. Conclusion Our results suggest that NKp30, NKp46 and NKG2D down-regulation represent an evasion mechanism associated to low NK cell activity, HPV-16 infection and cervical cancer progression.

Objectives:This study sought type and distribution of different pathologies in the cervical spine and a possible relationship between the MRI findings and the probable risk factors of the degenerative disorders. Material and methods: This descriptive cross-sectional research was carried out from October 2000 to January 2002 in three referral centers in Tehran. All the patients had referred for cervical MRI for neck pain and/or radicular pain. Results: Totally 342 patients entered the study. Sixty percent of patients were male. The mean age was 55.1 12.1 years. Seventy-nine percent of patients had abnormal MRI findings (238 patients (70% had signs of degenerative processes and 31 patients (9% had the other findings with a total 308 pathologies. The most common findings were disc bulging/ protrusion (%21.1, disc dehydration (%20.1, disc herniation (%18.1, and canal stenosis(%17.5. Older age, male gender and history of neck trauma were associated with increasing probability of degenerative changes (P-Values<0.05. Conclusion: Types of cervical spine pathologies are comparable to other reports. The anatomical distribution of disc bulging and protrusion in our study are similar to other reports. Likewise age, gender and a history of trauma to the neck were closely associated with the degenerative signs on the MR images.

    Rosli, Ruwaida; Kashani, Jamal; Kadir, Mohammed Rafiq Abdul

    There are many cases of injury in the cervical spine due to degenerative disorder, trauma or instability. This condition may produce pressure on the spinal cord or on the nerve coming from the spine. The aim of this study was, to analyze the stabilization of the cervical spine after undergoing laminectomy via computational simulation. For that purpose, a three-dimensional finite element (FE) model for the multilevel cervical spine segment (C1-C7) was developed using computed tomography (CT) data. There are various decompression techniques that can be applied to overcome the injury. Usually, decompression procedures will create an unstable spine. Therefore, in these situations, the spine is often surgically restabilized by using fusion and instrumentation. In this study, a lateral mass screw-rod fixation was created to stabilize the cervical spine after laminectomy. Material properties of the titanium alloy were assigned on the implants. The requirements moments and boundary conditions were applied on simulated implanted bone. Result showed that the bone without implant has a higher flexion and extension angle in comparison to the bone with implant under applied 1Nm moment. The bone without implant has maximum stress distribution at the vertebrae and ligaments. However, the bone with implant has maximum stress distribution at the screws and rods. Overall, the lateral mass screw-rod fixation provides stability to the cervical spine after undergoing laminectomy.

    Full Text Available Abstract Background This study evaluates the outcome and complications of decompressive cervical Laminectomy and lateral mass screw fixation in 110 cases treated for variable cervical spine pathologies that included; degenerative disease, trauma, neoplasms, metabolic-inflammatory disorders and congenital anomalies. Methods A retrospective review of total 785 lateral mass screws were placed in patients ages 16-68 years (40 females and 70 males. All cases were performed with a polyaxial screw-rod construct and screws were placed by using Anderson-Sekhon trajectory. Most patients had 12-14-mm length and 3.5 mm diameter screws placed for subaxial and 28-30 for C1 lateral mass. Screw location was assessed by post operative plain x-ray and computed tomography can (CT, besides that; the facet joint, nerve root foramen and foramen transversarium violation were also appraised. Results No patients experienced neural or vascular injury as a result of screw position. Only one patient needed screw repositioning. Six patients experienced superficial wound infection. Fifteen patients had pain around the shoulder of C5 distribution that subsided over the time. No patients developed screw pullouts or symptomatic adjacent segment disease within the period of follow up. Conclusion decompressive cervical spine laminectomy and Lateral mass screw stabilization is a technique that can be used for a variety of cervical spine pathologies with safety and efficiency.

    Full Text Available Se presenta un modelo tridimensional de elementos finitos para investigar el efecto producido por las fuerzas de oclusión en la distribución y magnitud del campo tensional sobre un premolar superior. De esta forma, se busca definir cuál es la situación de carga de oclusión más crítica desde el punto de vista tensional sobre el esmalte dental en la zona cervical que pudiese dar origen a una lesión del tipo no cariosa. Utilizando elementos finitos hexaédricos lineales y procesando el modelo con el programa SAMCEF se realiza un análisis numérico estático lineal considerando que el premolar es isótropo y homogéneo. Se definen siete estados de carga asociados a una fuerza de oclusión de 170 N para las cuales se investiga la distribución y magnitud de los campos tensionales sobre el premolar. Los resultados numéricos permiten concluir que las tensiones máximas sobre el premolar tienden a concentrarse en la zona cervical alcanzando sus valores máximos cuando la carga de 170 N actúa de forma inclinada a 45º con respecto a la vertical. La relevancia de la presente investigación radica en el hecho que numéricamente se demuestra que la distribución y zona en donde los campos tensionales tienden a concentrase y alcanzar sus valores máximos son coincidentes con las zonas del diente en donde clínicamente se observan lesiones no cariosas.A three-dimensional model of finite elements in order to investigate the effect produced by occlusion forces on both distribution and magnitude of the tensional field on an upper premolar is hereby presented. Thus, defining from a tensional point of view, which is the situation of the most critical occlusion loading on dental enamel capable to produce a non-cavity lesion is intended. By using finite linear hexahedral elements and processing the models through SAMCEF software, a static linear numerical analysis is performed, considering that premolar is isotropic and homogeneous.

Cervical cancer is one of the most common gynecologic malignant tumor, it is a serious threat to women's health, and in recent years it trends to target the younger ages. Human papilloma virus (HPV DNA) infection is the primary cause of cervical lesions, especially for cervical cancer. TCT is a new automatic cytology detection technology for cervical cytology screening. Colposcopy is an important application in early invasive cervical cancer screening. Combining the above mentioned three screening technologies could achieve the purposes of early detection, early diagnosis and early intervention of cervical precancerous lesions, so as to effectively prevent the occurrence of cervical cancer, reduce the morbidity and mortality of cervical cancer.

    (1)H nuclear magnetic resonance (NMR)-based metabonomics has been used to characterize the metabolic profiles of cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC). Principal component analysis (PCA) and orthogonal partial least-squares discriminant analysis (OPLS-DA) were used to model the systematic variation related to patients with CIN or CSCC with healthy controls. Potential metabolic biomarkers were identified using database comparisons, and the one-way analysis of variance (ANOVA) test was used to examine the significance of the metabolites. Compared with plasma obtained from the healthy controls, plasma from patients with CIN had higher levels of very-low density lipoprotein (VLDL), acetone, unsaturated lipid and carnitine, together with lower levels of creatine, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine, glycine, acetylcysteine, myo-inositol, choline and glycoprotein. Plasma from patients with CSCC had higher levels of acetate and formate, together with lower levels of creatine, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine and tyrosine compared with the plasma of the healthy controls. In addition, compared with the plasma of patients with CIN, the plasma of CSCC patients had higher levels of acetate, formate, lactate, isoleucine, leucine, valine, alanine, glutamine, histidine, tyrosine, acetylcysteine, myo-inositol, glycoprotein, α-glucose and β-glucose, together with lower levels of acetone, unsaturated lipid and carnitine. Moreover, the profiles showed high feasibility and specificity by statistical analysis with OPLS-DA compared to the Thinprep cytology test (TCT) by setting the histopathological outcome as standard. The metabolic profile obtained for cervical cancer is significant, even for the precancerous disease. This suggests a systemic metabolic response to cancer, which may be used to identify potential early diagnostic biomarkers of the cancer and to establish

    Full Text Available Abstract Background Human Papillomavirus (HPV is considered as a necessary, but not sufficient, cause of cervical cancer. In this study, we aimed to assess the prevalence of HPV in a series of pre-malignant and malignant cervical lesion cases, to identify the virus genotypes, and to assess their distribution pattern according to lesion type, age range, and other considered variables. The samples were submitted to histopathological revision examination and analysed by polymerase chain reaction (PCR for the presence of HPV DNA, followed by HPV typing by dot blot hybridisation. Findings Of the analysed samples, 53.7% showed pre-malignant cervical lesions, and 46.3% presented with cervical cancer. Most cancer samples (84.1% were classified as invasive carcinoma. The mean age of these cancer patients was 47.3 years. The overall HPV prevalence was 82.4% in patients with pre-malignant lesions and 92.0% in the cancer patients. HPV 16 was the most prevalent type, followed by HPV 18 and 58, including both single and double infections. Double infection was detected in 11.6% of the samples, and the most common combination was HPV 16+18. Conclusions Cervical cancer appears to occur in women in a lower age range in the studied area, compared to the situation in other Brazilian regions. Furthermore, among the patients with CIN 3 and those with cancer, we observed a higher proportion of married women, women with more than one sexual partner, smokers, and individuals with less than an elementary education, relative to their counterparts. Findings The overall HPV prevalence was 82.4% in patients with pre-malignant lesions and 92.0% in the cervical cancer patients from Northeast Brazil. HPV 16 was the most prevalent type, followed by HPV 18 and 58. The most common double infection was HPV 16+18. Cervical cancer appears to occur in women in a lower age range in the Northeast Brazil.

    Introduction Lateral mass screw (LMS) fixation with plates or rods is the current standard procedure for posterior cervical fusion. Recently, implants placed between the facet joints have become available as an alternative to LMS or transfacet screws for patients with cervical spondylotic radiculopathy. The purpose of this study was to evaluate the biomechanical stability of the DTRAX® cervical cage for single- and two-level fusion and compare this to the stability achieved with LMS fixation with rods in a two-level construct. Methods Six cadaveric cervical spine (C3–C7) specimens were tested in flexion–extension, lateral bending, and axial rotation to ±1.5 Nm moment without preload (0 N) in the following conditions: 1) intact (C3–C7), 2) LMS and rods at C4–C5 and C5–C6, 3) removal of all rods (LMS retained) and placement of bilateral posterior cages at C5–C6, 4) bilateral posterior cages at C4–C5 and C5–C6 (without LMS and rods), and 5) C4–C5 and C5–C6 bilateral posterior cages at C4–C5 and C5–C6 with rods reinserted. Results Bilateral posterior cervical cages significantly reduced range of motion in all tested directions in both single- and multilevel constructs (P<0.05). Similar stability was achieved with bilateral posterior cages and LMS in a two-level construct: 0.6°±0.3° vs 1.2°±0.4° in flexion–extension (P=0.001), (5.0°±2.6° vs 3.1°±1.3°) in lateral bending (P=0.053), (1.3°±1.0° vs 2.2°±0.9°) in axial rotation (P=0.091) for posterior cages and LMS, respectively. Posterior cages, when placed as an adjunct to LMS, further reduced range of motion in a multilevel construct (P<0.05). Conclusion Bilateral posterior cages provide similar cervical segmental stability compared with a LMS and rod construct and may be an alternative surgical option for select patients. Furthermore, supplementation of a lateral mass construct with posterior cages increases cervical spine stability in single- and multilevel conditions. PMID

    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.

    2015-05-01

    Radical trachelectomy is now recognized as a valid treatment option for young women with early-stage cervical cancer with lesions measuring less than 2 cm. However, for women with bulky lesions measuring greater than 2 cm, few data are available in the literature to guide management. There are currently 2 options available: either upfront radical trachelectomy or neoadjuvant chemotherapy followed by fertility-preserving surgery. Overall, both options offer very good oncologic outcome; however, the rate of fertility preservation and obstetrical outcome seem superior after neoadjuvant chemotherapy. Advantages and disadvantages of both options are discussed and a thorough literature review is provided. Issues to be further studied are also outlined.

    This study evaluates the prevalence and risk factors of non-carious cervical lesions (NCCLs) in a Brazilian population of workers exposed and non-exposed to acid mists and chemical products. One hundred workers (46 exposed and 54 non-exposed) were evaluated in a Centro de Referência em Saúde do Trabalhador - CEREST (Worker's Health Reference Center). The workers responded to questionnaires regarding their personal information and about alcohol consumption and tobacco use. A clinical examination was conducted to evaluate the presence of NCCLs, according to WHO parameters. Statistical analyses were performed by unconditional logistic regression and multiple linear regression, with the critical level of p smoking (p = 0.01) and age group (p = 0.04). The prevalence of NCCLs in the study population was particularly high (76.84%), and the risk factors for NCCLs were age, exposure to acid mists and smoking habit. Controlling risk factors through preventive and educative measures, allied to the use of personal protective equipment to prevent the occupational exposure to acid mists, may contribute to minimizing the prevalence of NCCLs.

    Cervical cancer disproportionately affects those in lower socio-economic groups. Mass media, including newspapers, are an important source of information about disease and how to prevent it. An analysis of UK national newspaper content between 2000 and 2009 is reported, assessing the extent to which information is provided about early signs and symptoms, risk factors and ways of preventing cervical cancer. The messages in newspapers targeted at readers in lower socio-economic groups are compared with the messages in other newspapers, and the impact of reporting the illness and death of the reality TV star, Jade Goody, on the level of medical information contained in articles is assessed. Tabloid or 'popular' newspapers are found to provide more information about early signs and symptoms, and no less information about risk factors, when compared with broadsheets or 'serious' papers. This is due to their greater use of personal stories of people with cervical cancer. The Jade Goody story was associated with an increase in information about early signs and symptoms, and about screening, but not (with the exception of the role played by social deprivation) about risk factors. Suggestions about how to approach public education via an entertainment format in mass media are made. PMID:20825461

    Full Text Available Human immunodeficiency virus type 1 (HIV-positive pregnant women require specific prophylactic and therapeutic approaches. The efficacy of established approaches is further challenged by co-infection with other sexually transmitted diseases (STDs. The objective of this study was to determine the prevalence of co-infections in pregnant women infected with different HIV-1 subtypes and to relate these findings, together with additional demographic and clinical parameters, to maternal and infant outcomes. Blood samples from pregnant women were collected and tested for syphilis, hepatitis B virus (HBV and hepatitis C virus (HCV. Human papillomavirus (HPV diagnosis was evaluated by the presence of alterations in the cervical epithelium detected through a cytopathological exam. Medical charts provided patient data for the mothers and children. Statistical analyses were conducted with STATA 9.0. We found a prevalence of 10.8% for HCV, 2.3% for chronic HBV, 3.1% for syphilis and 40.8% for HPV. Of those co-infected with HPV, 52.9% presented high-grade intraepithelial lesions or in situ carcinoma. Prematurity, birth weight, Apgar 1' and 5' and Capurro scores were similar between co-infected and non-co-infected women. The presence of other STDs did not impact maternal and concept outcomes. More than half of the patients presenting cervical cytology abnormalities suggestive of HPV had high-grade squamous intraepithelial lesions or cervical cancer, evidencing an alarming rate of these lesions.

  8. An Approach for registration method to find corresponding mass lesions in temporal mammogram pairs

    Directory of Open Access Journals (Sweden)

    Prof. Samir Kumar Bandyopadhyay

    2010-11-01

    Full Text Available Radiologists generally use multiple mammographic views to detect and characterize suspiciousregions. When radiologists discover a suspicious lesion in one view, they try to find a corresponding lesion in the other views. Views from different projections, typically cranio caudal (CC and medio lateral oblique (MLO views, allow for a better realization of the lesion. Most current computer aided detection (CAD systems differ considerably from radiologists in the way they use multiple views. These systems do not combine information from available views but instead analyse each view separately. Given the positive effect of multiview systems on radiologists' performance we expect that fusion of information from different views will improve CAD systems as well. Such multi-view CAD programs require regional registration methods to find corresponding regions in all available views. In this paper we concentrate on developing such a method for corresponding mass lesions in prior and In other words, starting from a current image containing a mass lesion, the method aims at locating the same mass lesion in the prior image. The method was tested on a set of 412 cancer cases. In each case a malignant mass, architectural distortion or asymmetry was annotated. In 92% of these cases the candidate mass detections by CAD included the cancer regions in both views. It was found that in 82% of the cases a correct link between the true. Positive regions in both views could be established by our method.Key words: Multiple View, Computer-Aided Detection, masses, mammography

    Recently neurologic complications after coronary artery bypass grafting (CABG) have received increasing attention. There is no detailed report about the risk factors for these complications, although stenosis in the cervical and intracranial arteries, especially in Japanese patients, latent ischemic brain lesions and preoperative neurological conditions are related to these events. In this prospective study, we evaluated occlusive lesions in the cervical carotid and intracranial arteries, silent brain infarction and cerebral deep white matter lesion with MRA and MRI in patients scheduled to undergo CABG to determine the prevalence of occlusive diseases in cervical carotid and intracranial arteries, latent ischemic change in the brain in this population and to identify preoperative risk factors for these patients. The subjects were 144 consecutive patients (103 men and 41 women, mean age 65.9{+-}9.2 years old) who were scheduled for CABG under elective conditions and who were examined by the same MRI apparatus using the same protocol between November 1998 and March 2001. After routine neurological examination and Mini-Mental State Examination (MMSE) were completed, MRI and MRA were obtained, then the prevalence of abnormalities on MRI and MRA studies and risk factors were evaluated. Cervical carotid artery stenosis with {>=}50% luminal narrowing was detected in 29.2% of the subjects, and that with {>=}75% luminal narrowing was detected in 16.0% of the subjects. Intracranial arterial stenosis showing {>=}50% luminal narrowing was detected in 38.2% of subjects, and that showing {>=}75% luminal narrowing was detected in 19.4% of subjects. Brain infarction was observed in 74.3% of subjects, cerebral deep white matter lesion showing grade 2 or higher on Fazekas classification was observed in 17.4% of the subjects. The characteristics, including possible risk factors of subjects with and without these abnormal findings, were compared. Patients with cervical carotid

    Full Text Available Abstract Background After unilateral cervical cord lesion at the C7/C8 border interrupting the dorsolateral funiculus in adult monkeys, neutralization of Nogo-A using a specific monoclonal antibody promoted sprouting of corticospinal (CS axons rostral and caudal to the lesion and, in parallel, improved functional recovery. In monkeys lesioned but not treated with the anti-Nogo-A antibody, the CS neurons in the contralesional primary motor cortex (M1 survived to the axotomy, but their soma shrank. Because the anti-Nogo-A treatment induces regeneration and/or sprouting of CS axons, it may improve access to neurotrophic factors. The question therefore arises as to whether anti-Nogo-A treatment prevents the soma shrinkage observed in the contralesional M1? Results Using the marker SMI-32, a quantitative and qualitative anatomical assessment of the pyramidal neurons in the layer V (thus including the CS cells in M1 was performed and compared across three groups of animals: intact monkeys (n = 5; monkeys subjected to the cervical cord lesion and treated with a control antibody (n = 4; monkeys with the cervical lesion and treated with anti-Nogo-A antibody (n = 5. SMI-32 positive neurons on the side contralateral to the lesion were generally less well stained than those on the ipsilesional hemisphere, suggesting that they expressed less neurofilaments. Nevertheless, in all three groups of monkeys, the amount of SMI-32 positive neurons in both hemispheres was generally comparable, confirming the notion that most axotomized CS neurons survived. However, shrinkage of CS cell body area was observed in the contralesional hemisphere in the two groups of lesioned monkeys. The cell surface shrinkage was found to be of the same magnitude in the monkeys treated with the anti-Nogo-A antibody as in the control antibody treated monkeys. Conclusion The anti-Nogo-A antibody treatment did not preserve the axotomized CS cells from soma shrinkage, indicating that the

    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

    Human papillomavirus (HPV) is a necessary cause of cervical cancer and its precursors. Increased expression of high-risk hrHPV viral oncogenes in abnormal cells might increase the expression of p16INK4a. We aimed to determine the role of p16INK4a in detecting hrHPV-transformed epithelial cells in liquid-based cervical cytology, and compared the results with hrHPV DNA testing by realtime polymerase chain reaction (RT-PCR). Fifty-seven cytological samples were tested for p16INK4a immunomarker and hrHPV DNA. Test performance of both tests was determined by comparing sensitivity, specificity and predictive values using available histological follow-up data as gold standard. Of 57 samples, 36 (63.2%) showed immunoreactivity for p16INK4a and 43 (75.4%) were hrHPV-infected. A fairly low concordance rate (k = 0.504) between p16INK4a immunolabelling and hrHPV DNA status was noted. For prediction of cervical intraepithelial neoplasia (CIN) II and worse lesions, p16INK4a had a sensitivity and specificity of 93.5% and 60%; whereas hrHPV DNA testing had a sensitivity and specificity of 100% and 20%. Dual testing by combining p16INK4a and hrHPV showed sensitivity and specificity of 100% and 33.3%. In conclusion, p16INK4a is useful in predicting severity of the cytological abnormalities. Although p16INK4a is more specific but less sensitive than hrHPV in detecting high-grade cervical lesions, a combination of both tests failed to demonstrate significant improvement in diagnostic sensitivity, specificity and predictive value. Larger-scale prospective studies are required to assess further whether this biomarker should be routinely used as primary screening tool independently or in combination with hrHPV testing to improve diagnostic accuracy in cervical cytology.

    Objective:Previous reports have shown that the gene promoter region of retinoic acid receptor β (RARβ) was hypermethylated in cervical carcinoma,implying the inhibition of gene transcription.The aim of this study was to investigate the association of cervical cancer development with the RARβ gene expression at the mRNA and protein level to assess the impact of RARβ as a marker for early detection of the cancer.Methods:We collected 126 cases of formalin fixed and paraffin embedded cervical tissue specimens as well as 37 cases of fresh tissue samples from women with cervicitis,cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC).The RARβ mRNA and protein expression was detected by quantitative RT-PCR and immunohistochemistry,respectively.Results:(1) The mRNA expression of RARβ in CIN and cervical cancer was markedly decreased compared to cervicitis with a statistically very significant difference,but no difference was found between CIN and cervical cancer.(2) RARβ protein was normally expressed in the epithelial cells of cervicitis and partially lost in a few cases,but with the development of cervical lesion pathogenesis and cancer,a significant loss of protein expression was detected in CIN (38%) and CSCC (57%) compared to cervicitis (P < 0.01).Conclusion:The downregulation of RARβ transcription or loss of protein expression is an important indicator of cervical cancer and its precursur lesions.The detection of RARβ expression coupled with aberrant methylation of the gene may become a biomarker for the early prognosis or diagnosis of the cancer.

    Full Text Available SUMMARY High-risk human papillomavirus (hr-HPV infection is necessary but not sufficient for cervical cancer development. Recently, P16INK4A gene silencing through hypermethylation has been proposed as an important cofactor in cervical carcinogenesis due to its tumor suppressor function. We aimed to investigate P16INK4A methylation status in normal and neoplastic epithelia and evaluate an association with HPV infection and genotype. This cross-sectional study was performed with 141 cervical samples from patients attending Hospital Moncorvo Filho, Rio de Janeiro. HPV detection and genotyping were performed through PCR and P16INK4A methylation by nested-methylation specific PCR (MSP. HPV frequency was 62.4% (88/141. The most common HPV were HPV16 (37%, HPV18 (16.3% and HPV33/45(15.2%. An upward trend was observed concerning P16INK4A methylation and lesion degree: normal epithelia (10.7%, low grade lesions (22.9%, high grade (57.1% and carcinoma (93.1% (p < 0.0001. A multivariate analysis was performed to evaluate an association between methylation, age, tobacco exposure, HPV infection and genotyping. A correlation was found concerning methylation with HPV infection (p < 0.0001, hr-HPV (p = 0.01, HSIL (p < 0.0007 and malignant lesions (p < 0.0001. Since viral infection and epigenetic alterations are related to cervical carcinoma, we suggest that P16INK4A methylation profile maybe thoroughly investigated as a biomarker to identify patients at risk of cancer.

    In the past decade, several different radiotherapy treatment plan evaluation and optimization schemes have been proposed as viable approaches, aiming for dose escalation or an increase of healthy tissue sparing. In particular, it has been argued that dose-mass plan evaluation and treatment plan optimization might be viable alternatives to the standard of care, which is realized through dose-volume evaluation and optimization. The purpose of this investigation is to apply dose-mass optimization to a cohort of lung cancer patients and compare the achievable healthy tissue sparing to that one achievable through dose-volume optimization. Fourteen non-small cell lung cancer (NSCLC) patient plans were studied retrospectively. The range of tumor motion was less than 0.5 cm and motion management in the treatment planning process was not considered. For each case, dose-volume (DV)-based and dose-mass (DM)-based optimization was performed. Nine-field step-and-shoot IMRT was used, with all of the optimization parameters kept the same between DV and DM optimizations. Commonly used dosimetric indices (DIs) such as dose to 1% the spinal cord volume, dose to 50% of the esophageal volume, and doses to 20 and 30% of healthy lung volumes were used for cross-comparison. Similarly, mass-based indices (MIs), such as doses to 20 and 30% of healthy lung masses, 1% of spinal cord mass, and 33% of heart mass, were also tallied. Statistical equivalence tests were performed to quantify the findings for the entire patient cohort. Both DV and DM plans for each case were normalized such that 95% of the planning target volume received the prescribed dose. DM optimization resulted in more organs at risk (OAR) sparing than DV optimization. The average sparing of cord, heart, and esophagus was 23, 4, and 6%, respectively. For the majority of the DIs, DM optimization resulted in lower lung doses. On average, the doses to 20 and 30% of healthy lung were lower by approximately 3 and 4%, whereas lung

    Full Text Available Non-carious cervical tooth lesions for many decades were attributed to the effects of abrasion and erosion mainly through toothbrush trauma, abrasive toothpaste, and erosive acids. However, though the above may be involved, more recently a biomechanical theory for the formation of these lesions has arisen, and the term abfraction was coined. The aim of this study was to investigate the biomechanics of abfraction lesions in upper canine teeth under axial and lateral loading conditions using a three-dimensional finite element analysis. An extracted human upper canine tooth was scanned by μCT machine (Skyscan, Belgium. These μCT scans were segmented, reconstructed, and meshed using ScanIP (Simpleware, Exeter, UK to create a three-dimensional finite element model. A 100 N load was applied axially at the incisal edge and laterally at 45° midpalatally to the long axis of the canine tooth. Separately, 200 N axial and non-axial loads were applied simultaneously to the tooth. It was found that stresses were concentrated at the CEJ in all scenarios. Lateral loading produced maximum stresses greater than axial loading, and pulp tissues, however, experienced minimum levels of stresses. This study has contributed towards the understanding of the aetiology of non-carious cervical lesions which is a key in their clinical management.

    Full Text Available This study evaluates the prevalence and risk factors of non-carious cervical lesions (NCCLs in a Brazilian population of workers exposed and non-exposed to acid mists and chemical products. One hundred workers (46 exposed and 54 non-exposed were evaluated in a Centro de Referência em Saúde do Trabalhador – CEREST (Worker’s Health Reference Center. The workers responded to questionnaires regarding their personal information and about alcohol consumption and tobacco use. A clinical examination was conducted to evaluate the presence of NCCLs, according to WHO parameters. Statistical analyses were performed by unconditional logistic regression and multiple linear regression, with the critical level of p < 0.05. NCCLs were significantly associated with age groups (18-34, 35-44, 45-68 years. The unconditional logistic regression showed that the presence of NCCLs was better explained by age group (OR = 4.04; CI 95% 1.77-9.22 and occupational exposure to acid mists and chemical products (OR = 3.84; CI 95% 1.10-13.49, whereas the linear multiple regression revealed that NCCLs were better explained by years of smoking (p = 0.01 and age group (p = 0.04. The prevalence of NCCLs in the study population was particularly high (76.84%, and the risk factors for NCCLs were age, exposure to acid mists and smoking habit. Controlling risk factors through preventive and educative measures, allied to the use of personal protective equipment to prevent the occupational exposure to acid mists, may contribute to minimizing the prevalence of NCCLs.

    The Forsyth County Cervical Cancer Prevention Project (FCP) is a community-based health education project funded by the National Cancer Institute. The target population includes around 25 000 black women age 18 and older who reside in Forsyth County, North Carolina. The overall goal of the program is to prevent mortality from cervical cancer by promoting Pap smears and return for follow-up care when needed. Based on the principles of social marketing, a plan to reach the target population with mass media educational messages through electronic and print channels was developed. Guided by marketing objectives, the target population was divided into relatively discrete segments. The segments included church attenders, patients in waiting rooms of public and selected health providers, female students at local colleges, shoppers, viewers of radio and television, newspaper readers, and business owners and managers. Introduction of the program was based on strategies developed for reaching the target population in each segment with television, radio and print mass media messages. Qualitative assessment of the mass media developed by the program indicated that all forms of communication helped to increase awareness of the program. PMID:10148691

    Cervical intraepithelial neoplasia (CIN) is caused by human papillomavirus (HPV) infection and is the precursor to cervical carcinoma. The completion of the HPV productive life cycle depends on the expression of viral proteins which further determines the severity of the cervical neoplasia. Initiation of the viral productive replication requires expression of the E2 viral protein that cooperates with the E1 viral DNA helicase. A decrease in the viral DNA replication ability and increase in the severity of cervical neoplasia is accompanied by simultaneous elevated expression of E6 and E7 oncoproteins. Here we reveal a novel and important role for the HPV16-E2 protein in controlling host cell cycle during malignant transformation. We showed that cells expressing HPV16-E2 in vitro are arrested in prophase alongside activation of a sustained DDR signal. We uncovered evidence that HPV16-E2 protein is present in vivo in cells that express both mitotic and DDR signals specifically in CIN3 lesions, immediate precursors of cancer, suggesting that E2 may be one of the drivers of genomic instability and carcinogenesis in vivo.

    Nuclear medicine imaging techniques continue to play a unique role in the evaluation of hepatic masses. Although many useful radiodiagnostic agents are available, the predominant nuclear medicine study used to evaluate hepatic masses in this decade is technetium-labeled red blood cell "blood-pool" scintigraphy. Hepatic blood-pool scintigraphy is extremely useful for the confirmation or exclusion of benign hepatic hemangiomas. This technique was first described in the 1970s and has vastly improved since that time. This improvement has been caused predominantly by advancements in instrumentation, especially the development of single photon emission computed tomography (SPECT) imaging. However, a perfusion/blood-pool mismatch remains unchanged as the hallmark finding for hepatic hemangiomas. The sensitivity and specificity of blood-pool scanning for the detection of hemangiomas has continued to increase over the years, and has not been equaled or surpassed by other radiographic modalities, with the possible exception of magnetic resonance imaging. Furthermore, blood-pool imaging is relatively inexpensive, simple to perform, and highly accurate. When a suspected hepatic hemangioma is confirmed by a positive radionuclide blood-pool study, the clinical evaluation of patients with hepatic masses can generally be terminated. PMID:8623050

    The diagnosis of a pancreatic mass lesion in the presence of chronic pancreatitis can be extremely challenging. At the same time, a high level of certainty about the diagnosis is necessary for appropriate management planning. The aim of this study was to establish current best evidence about which imaging methods reliably differentiate a benign from a malignant lesion, and show how that evidence is best applied. A diagnostic algorithm based on Bayesian analysis is proposed.

    Highlights: • The positive predictive value of an NML lesion on ultrasound ranges from 10 to 79%. • A sizable number of NML malignant lesions are pure DCIS or ILC. • Biopsy is indicated for histopathological diagnosis when an ultrasound NML lesion is recognized. - Abstract: Objective: To analyze the features of non-mass-like (NML) breast lesions on ultrasound (US) and determine their corresponding malignancy rate and to stratify these lesion patterns according to US BI-RADS categories. Materials and methods: One hundred sixty-four consecutive lesions were retrospectively classified into four types according to the US features, the corresponding positive predictive values (PPVs) were obtained. Clinical, imaging, and histopathological findings were reviewed. Results: Among the 164 lesions, 39 (24%) were classified as type Ia, 14 (8%) as type Ib, 39 (24%) as type IIa, 19 (12%) as type IIb, 19 (12%) as type III, and 34 (21%) as type IV. The PPVs for malignancy were 21% for type Ia, 79% for type Ib, 10% for type IIa, 58% for type IIb, 16% for type III, and 21% for type IV. All NML lesions were classified as BI-RADS category 4a (type IIa), 4b (type Ia, III and IV) and 4c (type Ib and IIb) according to their PPVs. There was a significantly higher frequency of malignancy among lesions of type Ib and type IIb compared with the other types (P < 0.01 for each). Lesions with associated calcifications, presence of abnormal axillary nodes, or a mammographic finding of suspected malignancy had a higher probability of malignancy (P < 0.05 for each). Conclusion: US is useful in clarifying the indication for biopsy of NML lesions. The types of US classifications used in our study establish reliable references for the NML patterns when stratified according to the BI-RADS categories.

    23 cases of unstable traumatic lesions of the lower cervical spine, without neurologic complication, were treated over a period of eight years. These cases consisted of eight dislocations, five subluxations, nine fracture-dislocations and one "tear drop" or fracture of the vertebral body. Six cases were treated conservatively and fifteen operatively. Two patients died in skeletal traction while awaiting surgical intervention. The surgical approaches were anterior (6 cases), posterior (8 cases) and combined (1 case). There was one case of transitory neurologic deficit immediately after surgery. One case required re-intervention. Overall they obtained satisfactory osteoligamentary consolidation. PMID:2055985

    The Authors have correlated 39 cervical diagnostic biopsies for squamous intraepithelial lesions (SILs) with correspective Papanicolau smears (PS), with relation to the presence or the absence of HPV of oncogenic type (HPV-one) detected by in situ hybridization (ISH). Agreement between cytological and histological diagnosis was present in 14 of 16 cases with detectable HPV-one and only in 12 of 23 cases without detectable HPV-one at ISH. The importance of the HPV type in the SILs with relation to the diagnostic accuracy of Papanicolaou smears has been discussed.

    Full Text Available Objective: To improve the sensitivity of Human Papillomavirus (HPV detection in plasma from high-grade cervical neoplasia patients (CIN III and cervical cancer (CC evaluating any likely correlation with disease stage.Method: We subjected plasma DNA isolates from 112 patients (CIN and ICC to a pre-PCR restoration treatment to improve detection sensitivity. HPV-specific sequences were detected by conventional PCR both in cervical scrapes and plasma DNA obtained from each patient. For every single DNA sample, both non-restored and restored isolates were PCR analyzed.Results: We detected HPV in plasma DNA isolates with significantly higher efficiency on restored plasma-DNA as compared to each non-restored equivalent, still maintaining close correlation with the clinical stage of the cases. By analyzing plasma-DNA isolates we could classify as HPV positive >50.0% of the cases that were previously known to be positive from the cervical scrape based assay. Interestingly, 100% of the cases in which subtype HPV18 was detected in cervical scrapes were also positive in plasma DNA.Conclusions: Restoration of plasma DNA from cervical cancer patients allows a more sensitive PCR-based HPV detection, maintaining the correlation to disease stage traditionally observed.

    AbstractBackgroundCervical squamous intra-epithelial lesions (SIL) are more frequent in HIV-positive women overall. However the appropriate age at which to begin and end cervical cancer screening for early detection of lesions in HIV-positive women is not clear. We assessed the age-specific prevalence of any SIL and SIL requiring colposcopy in HIV-positive women in Cameroon.MethodsWe enrolled, interviewed and conducted conventional cervical cytology in 282 women, aged 19--68 years, initiating antiretroviral therapy in three clinics in Cameroon. In bivariable analyses, the crude relationship between age and the presence of lesions was assessed using locally weighted regression (LOWESS) methods. In multivariate analyses, generalized linear models with prevalence as the outcome, an identity link and a binomial distribution, were used to estimate prevalence differences. Bias analyses were conducted to assess the potential effect of inaccuracies in cytology.ResultsSIL were detected in 43.5% of the 276 women with satisfactory samples, 17.8% of whom had ASC-H\\/HSIL. On average, women aged 26 to 59 tended to have a slightly higher prevalence of any SIL than other women (Prevalence difference PD: 6.5%; 95%CI: -11.4, 24.4%). This PD was a function of CD4 count (heterogeneity test p-value =0.09): amongst patients with CD4 counts less than 200cells\\/uL, the prevalence was higher in patients aged 26--59, while there was essentially no difference amongst women with CD4 counts greater than 200 cells\\/uL. ASC-H\\/HSIL were present in women as young as 19 and as old as 62. Overall the prevalence of ASC-H\\/HSIL increased by 0.7% (95%CI: -3.8%, 5.1%) per decade increase in age.ConclusionBoth severe and less severe lesions were prevalent at all ages suggesting little utility of age-targeted screening among HIV-positive women. Nevertheless, the long-term evolution of these lesions needs to be assessed in prospective studies.

    Skull vibration induces nystagmus in unilateral vestibular lesion (UVL) patients. Vibration of skull, posterior cervical muscles or inferior limb muscles alters posture in recent UVL patients. This study aimed to investigate the postural effect of vibration in chronic compensated UVL patients. Vibration was applied successively to vertex, each mastoid, each side of posterior cervical muscles and of triceps surae in 12 UVL patients and 9 healthy subjects. Eye movements were recorded with videonystagmography. Postural control was evaluated in eyes open (EO) and eyes closed (EC) conditions. Sway area, sway path, anteroposterior and medio-lateral sways were recorded.A vibration induced nystagmus (VIN) beating toward the healthy side was obtained for each UVL patient during mastoid vibration. In EO, only sway path was higher in UVL group during vibration of mastoids and posterior cervical muscles.The EO postural impairments of UVL patients could be related to the eye movements or VIN, leading to visual perturbations, or to a proprioceptive error signal, providing an erroneous representation of head position. The vibration-induced sway was too small to be clinically useful. Vestibulo-ocular reflex observed with videonystagmography during mastoid vibration seems more relevant to reveal chronic UVL than vestibulo-spinal reflex observed with posturography.

    Thirty cases of the mediastinal mass lesions were examined by computed tomography and diagnostic ability of CT was retrospectively evaluated. We devided them into two major groups: cystic and solid lesions. Cysts and cystic teratomas were differentiated on the thickness of their wall. Pericardial cysts were typically present at the cardiophrenic angle. In the solid mediastinal lesions, the presence of calcific and/or fatty components, the presence of necrosis, the irregularity of the margin and the obliteration of the surrounding fat layer were the clues to differential diagnosis and of evaluation for their invasiveness. Although differential diagnosis of the solid anterior mediastinal tumors was often difficult, teratomas with calcific and fatty componets were easily diagnosed. Invasiveness of the malignant thymoma and other malignant lesions were successfully evaluated to some extent. Neurogenic posterior mediastinal tumors were easily diagnosed because of the presence of the spine deformity and typical dumbbell shaped appearance. We stress that our diagnostic approach is useful to differentiate the mediastinal mass lesions.

    The aim of this study was to evaluate the impact of the surgical excisional procedures for cervical intraepithelial neoplasia (CIN) treatment both on subsequent fertility (cervical factor) and pregnancy complication (risk of spontaneous preterm delivery). We retrospectively analyzed 236 fertile women who underwent conization for CIN. We included in the study 47 patients who carried on pregnancy and delivered a viable fetus. Patients were asked about postconization pregnancies, obstetrical outcomes, and a possible diagnosis of secondary infertility caused by cervical stenosis. We evaluated the depth of surgical excision, the timing between cervical conization and subsequent pregnancies, surgical technique, and maternal age at delivery. We recorded 47 deliveries, 10 cases of preterm delivery; 8 of them were spontaneous. The depth of surgical excision showed a statistically significant inverse correlation with gestational age at birth. The risk of spontaneous preterm delivery increased when conization depth exceeded a cut-off value of 1.5 cm. Our data do not demonstrated a relation between conization and infertility due to cervical stenosis. PMID:24324288

    Full Text Available Abstract Background Previous studies have either investigated the relationship of HPV with oral cancer or the prevalence of HPV on the oral cavity. The purpose of this investigation was to study the prevalence of HPV in oral cavity of women with oral sex practices and cervical lesions. Methods Forty six (46 non-smokers and non-alcoholic patients attended the "Clínica de Displasias" of "Ciudad Juarez" were sampled. This population had a CIN diagnosis sometime between the previous six months. On previous consent they filled out a questionnaire related to their oral sex practices. Afterwards one swab from cheeks and another from palate/gum were taken; PCR was used to determine generic HPV, HPV16 and HPV18. Results Seventy two percent (72% of the patients stated to have oral sex practices regularly which all of them were positive to HPV either in oral mucus, palate/gum or both. The total of the given results showed that 35% had HPV16; among those distributed in 26% with regular oral sex practices and 9% stated as never practiced oral sex. An association was found between oral HPV16 positivity and progression to cervical CIN advanced lesions. On the other hand HPV18 was not detected. The frequency of HPV16 was higher in buccal mucosa (23% versus palate/gum (16%. Conclusions This study suggests that buccal HPV16 infection is associated with CIN progression.

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

    Full Text Available Abstract Background Women with Human Papilloma Virus (HPV persistence are characterized by high levels of IL-10 at cervix. We have determined whether polymorphisms of IL-10 gene promoter might be associated with increased risk of squamous intraepithelial cervical lesions (SICL and whether exist significative differences of IL-10 mRNA expression at cervix and systemic and serum IL-10 protein between SICL cases and non-Cervical Lesions (NCL. Methods Peripheral blood samples from SICL (n = 204 and NCL (n = 166 were used to detect IL-10 promoter polymorphisms at loci -592A/C (rs1800872, -819C/T (rs1800871, -1082A/G (rs1800896, -1352A/G (rs1800893, by allelic discrimination and to evaluate serum IL-10 protein. Cervical epithelial scrapings from NCL and biopsies from SICLs were used for HPV-typing and to evaluate IL-10 mRNA expression level. The systemic and local IL-10 mRNA expression levels were measured by real time-PCR. Genotypic and allelic frequencies of the selected polymorphisms were analyzed by logistic regression, adjusting by age and HPV-genotype, to determine the association with SICL. Results No significant differences were found between genotype frequencies at loci −819, -1082, and −1352. Individuals carrying at least one copy of risk allele A of polymorphism −592 had a two-fold increased risk of developing SICL [adjusted odds ratio (OR, 2.02 (95% CI, 1.26-3.25, p = 0.003], compared to NCL. The IL-10 mRNA expression and serum IL-10 protein, were significantly higher in SICL cases (p  Conclusions The −592 polymorphism is associated with increased risk of SICL and can serve as a marker of genetic susceptibility to SICL among Mexican women. According to IL-10 levels found in SICL, IL-10 can be relevant factor for viral persistence and progression disease.

    Human papillomavirus (HPV) is widely known as a cause of cervical cancer (CC) and cervical intraepithelial neoplasia (CIN). HPVs related to cancer express two main oncogenes, i.e. E6 and E7, considered as tumorigenic genes; their integration into the host genome results in the abnormal regulation of cell cycle control. Due to their peculiarities, these oncogenes represent an excellent target for cancer immunotherapy. In this work the authors highlight the potential use of therapeutic vaccines as safe and effective pharmacological tools in cervical disease, focusing on vaccines that have reached the clinical trial phase. Many therapeutic HPV vaccines have been tested in clinical trials with promising results. Adoptive T-cell therapy showed clinical activity in a phase II trial involving advanced CC patients. A phase II randomized trial showed clinical activity of a nucleic acid-based vaccine in HPV16 or HPV18 positive CIN. Several trials involving peptide-protein-based vaccines and live-vector based vaccines demonstrated that these approaches are effective in CIN as well as in advanced CC patients. HPV therapeutic vaccines must be regarded as a therapeutic option in cervical disease. The synergic combination of HPV therapeutic vaccines with radiotherapy, chemotherapy, immunomodulators or immune checkpoint inhibitors opens a new and interesting scenario in this disease.

    Full Text Available Introduction: In vivo magnetic resonance spectroscopy (MRS is an established technique for evaluation of malignant tumors in brain, breast, prostate, etc., However, its efficacy in the diagnosis of musculoskeletal (MSK mass lesions is yet to be established. We present our experience with MRS of these lesions. Materials and Methods: Magnetic resonance imaging (MRI, dynamic contrast-enhanced MRI and single-voxel 1 H MRS was performed in 30 consecutive patients with histologically proven benign and malignant MSK tumors/mass lesions each, on a 1.5-T magnetic resonance scanner. MRS was performed with echo times (TE of 40, 135 and 270 ms. A clearly identifiable peak at 3.2 ppm in at least two of the three spectra acquired at the three TE was taken as positive for choline. MRS imaging and enhancement patterns were compared in these two groups and were analyzed by a Radiologist blinded to the histopathological findings. Results: Ages of patients in the malignant age group ranged from 2 to 65 years (M: F - 19:11 while that of patients in the benign group ranged from 7 months to 56 years (M: F - 17:13. There were two patients with Type I curve, 18 with Type II curve and 10 with Type III curve on dynamic contrast enhanced images in the malignant group while there were no patients with Type I curve, 5 with Type II curve and 25 with Type III curve in the benign group. The sensitivity of MRS for predicting malignancy was 60%, specificity was 93.33%, positive predictive value was 90%, negative predictive value was 70% and accuracy was 76.66%. Conclusion: MRS is a promising technique for evaluation of MSK mass lesions. The accuracy at present remains low. We recommend that it be used as an adjunct to routine MRI.

    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.

    Full Text Available The identification of new biomarkers for preneoplastic pancreatic lesions (PanINs, IPMNs and early pancreatic ductal adenocarcinoma (PDAC is crucial due to the diseases high mortality rate upon late detection. To address this task we used the novel technique of matrix-assisted laser desorption/ionization (MALDI imaging mass spectrometry (IMS on genetically engineered mouse models (GEM of pancreatic cancer. Various GEM were analyzed with MALDI IMS to investigate the peptide/protein-expression pattern of precursor lesions in comparison to normal pancreas and PDAC with cellular resolution. Statistical analysis revealed several discriminative m/z-species between normal and diseased tissue. Intraepithelial neoplasia (PanIN and intraductal papillary mucinous neoplasm (IPMN could be distinguished from normal pancreatic tissue and PDAC by 26 significant m/z-species. Among these m/z-species, we identified Albumin and Thymosin-beta 4 by liquid chromatography and tandem mass spectrometry (LC-MS/MS, which were further validated by immunohistochemistry, western blot, quantitative RT-PCR and ELISA in both murine and human tissue. Thymosin-beta 4 was found significantly increased in sera of mice with PanIN lesions. Upregulated PanIN expression of Albumin was accompanied by increased expression of liver-restricted genes suggesting a hepatic transdifferentiation program of preneoplastic cells. In conclusion we show that GEM of endogenous PDAC are a suitable model system for MALDI-IMS and subsequent LC-MS/MS analysis, allowing in situ analysis of small precursor lesions and identification of differentially expressed peptides and proteins.

    Full Text Available Improved methods for the accurate identification of both the presence and severity of cervical intraepithelial neoplasia (CIN and extent of spread of invasive carcinomas of the cervix (IC are needed. Differential scanning calorimetry (DSC has recently been shown to detect specific changes in the thermal behavior of blood plasma proteins in several diseases. This methodology is being explored to provide a complementary approach for screening of cervical disease. The present study evaluated the utility of DSC in differentiating between healthy controls, increasing severity of CIN and early and advanced IC. Significant discrimination was apparent relative to the extent of disease with no clear effect of demographic factors such as age, ethnicity, smoking status and parity. Of most clinical relevance, there was strong differentiation of CIN from healthy controls and IC, and amongst patients with IC between FIGO Stage I and advanced cancer. The observed disease-specific changes in DSC profiles (thermograms were hypothesized to reflect differential expression of disease biomarkers that subsequently bound to and affected the thermal behavior of the most abundant plasma proteins. The effect of interacting biomarkers can be inferred from the modulation of thermograms but cannot be directly identified by DSC. To investigate the nature of the proposed interactions, mass spectrometry (MS analyses were employed. Quantitative assessment of the low molecular weight protein fragments of plasma and urine samples revealed a small list of peptides whose abundance was correlated with the extent of cervical disease, with the most striking plasma peptidome data supporting the interactome theory of peptide portioning to abundant plasma proteins. The combined DSC and MS approach in this study was successful in identifying unique biomarker signatures for cervical cancer and demonstrated the utility of DSC plasma profiles as a complementary diagnostic tool to evaluate

    To compare the rates and accuracy of digital breast tomosynthesis (DBT) and 2D digital mammography (DM) for detecting and diagnosing mass-like lesions in dense breasts. Mediolateral and craniocaudal images taken with DBT (affected breast) and DM (both breasts) of the dense breasts of 631 women were assessed independently using Breast Imaging Reporting and Data System (BI-RADS) scores. Images were compared for detection and diagnostic accuracy for masses; sensitivity and specificity of diagnosis; false-negative and recall rates; and clarity of display, particularly of margins and spicules. Histopathology was conducted via surgical biopsies of all patients. The detection and diagnostic accuracy rates of DBT images (84.3% and 82.3%, respectively) were significantly higher than that of DM (77.3% and 73.4%; p < 0.01, both). The sensitivity and specificity of DBT (68.1% and 95.2%) were higher than that of DM (58.8% and 86.7%), whereas the recall rate of DBT was lower (3.6% cf. 9.8%). The number of cases of benign circumscribed masses and malignant spiculated masses detected by DBT (172 and 182) was significantly higher than the number detected through DM (75 and 115; p < 0.01, both). Radiologists assigned higher BI-RADS scores for probability of malignancy to DBT images than DM, to lesions proved malignant (p = 0.025); for benign cases, the methods were comparable (p = 0.065). Compared with DM, DBT yielded significantly higher rates of detection and diagnostic accuracy for benign and malignant masses, with greater sensitivity and specificity and lower recall rates. In addition, DBT images facilitated analysis of margins, and the rate of accuracy for judgments of malignancy probability was higher, as proved on biopsy. PMID:27296324

    International Nuclear Information System (INIS)

    Full text: A 54-year-old male, lifelong non-smoker, presented to the authors' hospital with a 5-day history of fever and productive cough, not improving on oral amoxicillin. His past medical history was unremarkable. On examina tion, he was febrile, tachycardic and tachypneic, and had right basal crackles on auscultation. Initial blood tests revealed a leucocytosis with increased neutrophils and normal lymphocytes. C-reactive protein was elevated at 312 mg/L 5). The coagulation profile was unremarkable. The initial chest X-ray (CXR) showed areas of opacifi cation in the right lower lobe and a right paratracheal mediastinal bulging (Fig, 1). A previous CXR from 6 years before, unrelated to this recent presentation, was normal. Further evaluation by contrast-enhanced chest CT (SIEMENS Sensation 16 (Siemens, Erlangen, Germany); slice thickness 3 mm) showed a well-defined heteroge neous 4.0 x 4.8 cm mass lesion in the superior mediast num with densities of 60-70 HU, separate from vessels, the esophagus or the trachea (Fig. 2a) along with bilateral lower lobe patchy confluent pulmonary infiltrates (not shown), more conspicuous on the right. The patient's hospital stay was complicated by a non-ST elevation myocardial infarction, which precluded him from having a transbronchial biopsy of the mediastinal mass. The patient's serum tested positive for mycoplasma pneumo niae antibodies with a titre of 640 40); the pneumonia was successfully treated with a course of oral doxycycline administered over 14 days, the symptoms fully resolving. He was eventually discharged, having recovered from the pneumonia and from the myocardial infarction. A subs quent CT scan performed 3 months later showed persis tence of the mediastinal mass with no significant changes in size or density (Fig. 2b); the bilateral pneumonic infil trates have fully resolved. The ensuing endobronchial ultrasound (EBUS)-guided needle aspiration with biopsy of the mediastinal mass produced a sample of macrophages

    Full Text Available Background:Chondral lesions of the knee are commonly found during arthroscopic partial meniscectomy. The literature advises against arthroscopic medial meniscectomy in the presence of advanced chondral derangement because of unfavorable outcome. Recent studies have shown an association between obesity and chondropathy in patients with meniscal tears. The aim of this study was to assess whether body mass index (BMI correlates with the severity of chondral lesions in patients with isolated medial meniscus tears (i.e. without ligamentous or lateral meniscal injury. Materials and Methods: 837 knee arthroscopies were performed in a regional referral center of arthroscopic surgery between January 2011 and December 2012. Of these 168 (109 males, 59 females patients with no axial knee deformity and no radiological signs of osteoarthritis who have had arthroscopic debridement for isolated torn medial meniscus were included in the study. The correlation between different demographic factors and the level of chondral damage reported at surgery was evaluated. The mean age of patient was 50 years (range 13-82 years and an average BMI was 28.2 kg/m [2] (range17.5-42.5 kg/m [2] . Results: Overall, regression analysis showed both age and BMI to be linearly correlated to chondral score (r = 0.53, P < 0.04; however, there were no advanced chondral lesions found in patients younger than 40 years of age and all severe lesions were at age 50 years or more. Therefore, further analysis was performed for age subgroups: patients were grouped as younger than 40, between the age of 40 and 50 (middle age and older than 50 years. The BMI was linearly correlated to the severity of chondral score exclusively in the middle aged group (i.e. 40-50 years old. There was no correlation between activity level and chondral damage. Women had worse chondral lesions than men in all age groups. Conclusion: Higher BMI in middle aged patients with isolated medial meniscus tears and

    Objective: To explore the feasibility of DSCT dual-energy technique in pulmonary mass lesions. Methods: A total of 100 patients with pulmonary masses underwent conventional plain CT scan and dual-energy enhanced CT scan. The virtual non-contrast (VNC) images were obtained at post-processing workstation.The mean CT value,enhancement value,signal to noise ratio (SNR), image quality and radiation dose of pulmonary masses were compared between the two scan techniques using F or t test and the detectability of lesions was compared using Wilcoxon test. Results: There was no statistically significant difference among VNC (A) (32.89 ± 12.58) HU,VNC (S) (30.86 ± 9.60) HU and conventional plain images (35.89 ± 9.99) HU in mean CT value of mass (F =2.08, P>0.05). There was statistically significant difference among VNC (A) (3.29 ± 1.45), VNC (S) (3.93 ± 1.49) and conventional plain image (4.61 ± 1.50) in SNR (F =6.01, P<0.05), which of conventional plain scan was higher than that of VNC.The enhancement value of mass in conventional enhanced scan (60.74 ± 13.9) HU and distribution of iodine from VNC (A) (58.26 ± 31.99) HU was no statistically significant difference (t=0.48, P>0.05), but there was a significant difference between conventional enhanced scan (56.51 ± 17.94) HU and distribution of iodine from VNC (S) (52.65 ± 16.78) HU (t=4.45, P<0.05). There was no statistically significant difference among conventional plain scan (4.69 ± 0.06) and VNC (A) (4.60 ± 0.09), VNC (S) (4.61 ±0.11) in image quality at mediastinal window (F=3.014, P>0.05). The appearance, size, internal features of mass (such as necrosis, calcification and cavity) were showed the same in conventional plain scan, VNC (A) and VNC (S). Of 41 patients with hilar mass, 18 patients were found to have lobular and segmental perfusion decrease or defect. Perfusion defect area was found in 59 patients with peripheral lung mass. The radiation dose of dual-energy enhanced scan was lower than that of

    Purpose: Most of the patients who died of breast cancer have developed bone metastases. To understand the pathogenesis of bone metastases and to analyze treatment response of different bone remodeling therapies, preclinical animal models are examined. In breast cancer, bone metastases are often bone destructive. To assess treatment response of bone remodeling therapies, the volumes of these lesions have to be determined during the therapy process. The manual delineation of missing structures, especially if large parts are missing, is very time-consuming and not reproducible. Reproducibility is highly important to have comparable results during the therapy process. Therefore, a computerized approach is needed. Also for the preclinical research, a reproducible measurement of the lesions is essential. Here, the authors present an automated segmentation method for the measurement of missing bone mass in a preclinical rat model with bone metastases in the hind leg bones based on 3D CT scans. Methods: The affected bone structure is compared to a healthy model. Since in this preclinical rat trial the metastasis only occurs on the right hind legs, which is assured by using vessel clips, the authors use the left body side as a healthy model. The left femur is segmented with a statistical shape model which is initialised using the automatically segmented medullary cavity. The left tibia and fibula are segmented using volume growing starting at the tibia medullary cavity and stopping at the femur boundary. Masked images of both segmentations are mirrored along the median plane and transferred manually to the position of the affected bone by rigid registration. Affected bone and healthy model are compared based on their gray values. If the gray value of a voxel indicates bone mass in the healthy model and no bone in the affected bone, this voxel is considered to be osteolytic. Results: The lesion segmentations complete the missing bone structures in a reasonable way. The mean

    Despite the fact that one-step adhesives are currently used routinely in clinical practice, long-term studies on their clinical performance are scarce. The objective of this randomized controlled clinical trial was to test the hypothesis that a 2-hydroxyethyl methacrylate (HEMA)-free one-step self-etch adhesive performs worse than a conventional multistep etch-and-rinse adhesive. Two-hundred and seventy-six non-carious cervical lesions in 52 patients were restored with a micro-hybrid composite (Gradia Direct; GC). These restorations were bonded in random order either with the HEMA-free one-step adhesive G-Bond (GC) or with the 'gold-standard' (control) three-step adhesive Optibond FL (Kerr). The restorations were evaluated after 6, 12, 24, and 36 months of clinical service regarding retention, marginal adaptation, microleakage, caries occurrence, and sensitivity. After a medium-long period of 3 yr, similar success in clinical performance was observed for the simplified all-in-one adhesive and the conventional three-step adhesive. However, the one-step adhesive exhibited significantly more incisal marginal defects and discolorations. Whereas marginal degradation appeared to arrest for the multistep etch-and-rinse adhesive after 12 months, the enamel margins of the restorations bonded with the one-step self-etch adhesive continued to deteriorate. These incisal marginal defects were, however, small and could easily be removed by polishing. For both adhesives, large and sclerosed lesions appeared to be at higher risk of retention loss.

    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. A Case of a Solid Renal Mass Together with a Cystic Pancreatic Lesion in a 50-Year-Old Patient

    Directory of Open Access Journals (Sweden)

    Satorres Rosas J

    2005-03-01

    Full Text Available CONTEXT: Pancreatic cysts may be incidentally detected in asymptomatic patients evaluated for other clinical manifestations. Microcystic adenomas are particularly rare among pancreatic cyst neoplasms. They are benign lesions and can present as solitary pancreatic tumors or as a radiological manifestation combined with other cystic and tumoral lesions affecting different organs. CASE REPORT: A 50-year-old man presented with hematuria. A computed tomography scan of the abdomen showed a 9-centimeter renal mass in the left kidney consistent with a renal-cell carcinoma as well as a cystic lesion the head of the pancreas. The histopathological study of the cystic mass, following a computed tomography guided biopsy, showed a microcystic adenoma. Therefore, further studies were performed so as to assess the relationship between both lesions and determine the final diagnosis. CONCLUSIONS: Microcystic adenomas are exceedingly rare tumors among pancreatic cysts. The combination of a solid renal mass and a pancreatic cystic lesion should lead to a broad differential diagnosis. Pancreatic magnetic resonance imaging has been proven to be particularly useful in evaluating cystic masses. The presence of walls and internal septations in the pancreatic mass with gadolinium enhancement should raise the possibility of an underlying Von Hippel-Lindau syndrome.

    Full Text Available Context Appropriate surgical exploration and resection of pancreatic carcinoma depends on accurate preoperative evaluation. Objective Determine the accuracy of endoscopic ultrasound in predicting the need for surgical exploration in patients with solid pancreatic masses deemed by computer tomography to be resectable without venous grafting (absence of distant metastatic disease or major vascular involvement. Patients All patients between March 2000 and November 2003 with focal pancreatic mass lesions deemed to be surgically resectable by computer tomography. Fortynine patients participated (29 males, 20 females; age range: 40-86 years. Intervention Preoperative linear-array endoscopic ultrasound. Main outcome measure Surgical pathology compared to computer tomography and endoscopic ultrasound results. Results Out of the 49 patients, 33 (67.3% had pancreatic neoplasms and 16 (32.7% had chronic pancreatitis. Endoscopic ultrasound correctly diagnosed all 16 patients with chronic pancreatitis. Endoscopic ultrasound correctly identified 18 (54.5% of those with neoplasms as having unresectable disease while 6 (18.2% patients were appropriately identified as resectable by endoscopic ultrasound. The remaining 9 patients (27.3% were deemed resectable by endoscopic ultrasound, but were unresectable at the time of surgery. None of the patients were falsely designated as unresectable by endoscopic ultrasound. Conclusion Endoscopic ultrasound is an important compliment to computed tomography in predicting resectability and in avoiding nontherapeutic laparotomy of solid pancreatic neoplasms. Moreover, endoscopic ultrasound classification did not discourage surgery of resectable pancreatic masses.

    Purpose: To assess the technical feasibility of apparent diffusion coefficient (ADC) mapping based on free-breathing diffusion-weighted magnetic resonance (DW-MR) outside the CNS in children. Material and Methods: Twelve children with mass lesions of varied histopathology were scanned with short-tau inversion recovery (STIR), contrast-enhanced T1-weighted (CE-T1W), and diffusion-weighted (b = 0, 500 and 1,000 s/mm{sup 2}) sequences. ADC maps were calculated. Lesion-to-background signal intensity ratios were measured and compared between STIR/CE-T1W/ADC overall (Friedman test) and between viable embryonal tumors and other lesions (Kruskal-Wallis test). Results: ADC maps clearly depicted all lesions. Lesion-to-background signal intensity ratios of STIR (median 3.7), CE-T1W (median 1.4), and ADC (median 1.6) showed no overall difference (chi-square = 3.846; P = 0.146), and there was no difference between viable embryonal tumors and other lesions within STIR/CE-T1W/ADC (chi-square 1.118/0.669/<0.001; P = 0.290/0.414/1.000, respectively). Conclusion: ADC mapping is feasible in free-breathing imaging of pediatric mass lesions outside the CNS using standard clinical equipment.

    A 2-year randomized, controlled prospective study evaluated the clinical effectiveness of a one-step self-etch adhesive and a "gold-standard" three-step etch-and-rinse adhesive in non-carious Class-V lesions. The null hypothesis tested was that the one-step self-etch adhesive does perform clinically equally well as the three-step etch-and-rinse adhesive. A total of 161 lesions in 26 patients were restored with Clearfil AP-X (Kuraray). The restorations were bonded either with the "all-in-one" adhesive Clearfil S3 Bond (Kuraray) or with the three-step etch-and-rinse adhesive Optibond FL (Kerr). The restorations were evaluated at baseline and after 6 months, 1 and 2 years, regarding their retention, marginal adapation, marginal discoloration, caries occurrence, preservation of tooth vitality and post-operative sensivity. Retention loss, severe marginal defects and/or discoloration that needed intervention (repair or replacement) and the occurrence of caries were considered as clinical failures. The recall rate at 2 years was 93.8%. Only one Clearfil S3 Bond restoration was lost at the 2-year recall. All other restorations were clinically acceptable. The number of restorations with defect-free margins decreased severely during the 2-year study period (to 6.7% and 25.3% for Clearfil S3 Bond and Optibond FL, respectively). The Clearfil S3 Bond restorations presented significantly more small marginal defects at the enamel side than the Optibond FL restorations (Clearfil S3 Bond: 93.3%; Optibond FL: 73.3%; p = 0.000). Superficial marginal discoloration increased in both groups (to 53.3% and 36% for Clearfil S3 Bond and Optibond FL, respectively) and was also more pronounced in the Clearfil S3 Bond group (p = 0.007). After 2 years, the simplified one-step self-etch adhesive Clearfil S3 Bond and the three-step etch-and-rinse adhesive Optibond FL were clinically equally successful, even though both adhesives were characterized by progressive degradation in marginal

  8. Serial type-specific human papillomavirus (HPV) load measurement allows differentiation between regressing cervical lesions and serial virion productive transient infections

    International Nuclear Information System (INIS)

    Persistent high-risk human papillomavirus (HPV) infection is strongly associated with the development of high-grade cervical intraepithelial neoplasia (CIN) or cancer. Not all persistent infections lead to cancer. Viral load measured at a single time-point is a poor predictor of the natural history of HPV infections. However the profile of viral load evolution over time could distinguish nonprogressive from progressive (carcinogenic) infections. A retrospective natural history study was set up using a Belgian laboratory database including more than 800,000 liquid cytology specimens. All samples were submitted to qPCR identifying E6/E7 genes of 18 HPV types. Viral load changes over time were assessed by the linear regression slope. Database search identified 261 untreated women with persistent type-specific HPV DNA detected (270 infections) in at least three of the last smears for a average period of 3.2 years. Using the coefficient of determination (R²) infections could be subdivided in a latency group (n = 143; R² < 0.85) and a regressing group (n = 127; R² ≥ 0.85). In (≥3) serial viral load measurements, serial transient infections with latency is characterized by a nonlinear limited difference in decrease or increase of type-specific viral load (R² < 0.85 and slopes between 2 measurements 0.0010 and −0.0010 HPV copies/cell per day) over a longer period of time (1553 days), whereas regression of a clonal cell population is characterized by a linear (R² ≥ 0.85) decrease (−0.0033 HPV copies/cell per day) over a shorter period of time (708 days; P < 0.001). Using serial HPV type-specific viral load measurements we could for the first time identify regressing CIN2 and CIN3 lesions. Evolution of the viral load is an objective measurable indicator of the natural history of HPV infections and could be used for future triage in HPV-based cervical screening programs

    Teratoma of the head and neck is a rare lesion comprising 6 % of all teratomas, with only 3 % occurring in the cervical region [1]. Most are non-malignant lesions consisting of a variety of tissues of variable maturity, commonly with neuroepithelial and thyroid elements. They often present as a large cystic mass in the neck of a neonate or infant and frequently cause respiratory embarrassment due to local mass effect necessitating urgent surgical intervention. They may be difficult to distinguish from cystic hygromas, both clinically and radiologically. Imaging plays an important role in the assessment of these lesions, especially in preparation for surgery. We present a case of cervical teratoma and emphasise the role of MRI. (orig.)

    OBJECTIVE To investigate human papilloma virus (HPV) infections and the distribution of its subtypes in patients with cervical lesions and put forward counter measures for prevention and treatment of the disease. METHODS Cervical exfoliated cells collected from a total of 600 patients with cervical lesions were detected with Flow-through hybridization and gene chip technology, and followed by a complete evaluation of the HPV infection in related to different subtypes of cervical lesions. RESULTS The total HPV infection rate reached 78. 0%. The high-risk and low-risk HPV infection rates of patients with cervicitis/ condyloma acuminatum were 73. 1% and 18. 1%, respectively. The difference was statistically significant (P<0. 05). The high-risk and low-risk HPV infection rates of patients with cervical intraepithelial neoplasia (CIN) were 82. 6% and 7. 9%, respectively, the difference was statistically significant (P<0. 01). The high-risk and low-risk HPV infection rates of patients with cervical cancer were 96. 0% and 0, respectively, the difference was statistically significant (P<0. 01). The high-risk HPV infection rate increased with the degree of exacerbating of cervical lesions. The rate of single-type HPV infection was significantly higher than that of multi-type HPV infection in all kinds of cervical lesions (P<0. 01), while the rate of multi-type HPV infection increased with the increasing severity of cervical lesions. Different subtypes of HPV distributed differently in cervix lesions. CONCLUSION Detection of HPV subtypes is helpful for screening of the cervical lesions and diagnosis of the condition. For those patients infected especially with high-risk HPV, it is critical to conduct the early diagnosis, timely treatment and close follow-up to block the persistent HPV infection and prevent cervical cancer.%目的 探讨宫颈病变患者人乳头状瘤病毒(HPV)的感染状态及其亚型分布,提出预防治疗疾病的干预措施.方法 采用导流

    We report on a rare case of connecting rod migration into the posterior cranial fossa after posterior cervical decompression and lateral mass screw fixation. A 55-year-old male patient who was operated on for ossification of posterior longitudinal ligament complained of sudden-onset giddiness followed by loss of consciousness one and half year following surgery. CT scan showed migration of left-sided connecting rod into the right cerebellum through foramen magnum. The patient was operated on for rod removal but he sustained a cardiorespiratory arrest and died on the eighth postoperative day. Autopsy confirmed damage to the right cerebellum due to rod migration. The clinician should be aware that superior rod migration is a rare but potentially disastrous complication. Regular follow-up with radiological evaluation should be done to look for implant loosening, migration, and non-union even in asymptomatic patients. The implant should be subsequently removed after it has served its purpose. PMID:26748502

    Background. Persistent infection with high-risk human papillomavirus (HR-HPV) has been demonstrated to be the necessary causal factor for developing cervical cancer. To know the most prevalent HR-HPV in different geographical areas is important to design diagnostic tests and implementation of vaccines. Objectives. The goal of this study is to evaluate the prevalence of HR-HPV in a total of 1001 patients, 198 with normal cytology results, 498 with low-grade squamous intraepithelial lesion (LSIL), and 205 with high-grade squamous intraepithelial lesion (HSIL) who attended our gynaecology department for opportunistic screening of HPV infection. Study design. Cervical samples were taken in a PreservCyt vial (Cytyc Corporation, Boxborough, MA). Hybrid capture assay was carried out following the manufacturer's instructions (Digene Corp., Gaithersburg, MD). All samples were further studied with polymerase chain reaction (PCR) (Linear Array HPV Genotyping Test, Roche Diagnostics, Mannheim, Germany). Results. Genotype 16 was the most prevalent HR-HPV in the three groups, 17.8% in the patients with normal cytology results, 22.3% in the LSIL group, and 60% in the HSIL group. Genotype 18 had a very low prevalence in all groups. Other HR-HPV genotypes such as genotype 31, genotype 58 and genotype 52 were found in significant numbers in HSIL patients. Discussion. Our data show that genotypes 16, 31, 58, and 52 are the most prevalent HR-HPV in cervical samples with severe intraepithelial lesion in Spain. There may be some geographical variation in prevalence of carcinogenic types, and it must be considered for designing diagnostic tests and vaccine.

    Background In response to antigen naive CD8+, T cells differentiate into effector cells, which express Natural killer (NK) receptors, lose CD28 expression, and die by apoptosis. However, in smaller quantities, the cells are retained for subsequent exposure to the same antigen. Knowledge is limited regarding whether the percentages of CD28-, Effector memory (EMRAnull/dim), and the CD16+/CD56 + CD8+ T cells of women with low-grade cervical lesions are altered at a systemic level.

  1. Augmented serum level of major histocompatibility complex class I-related chain A (MICA) protein and reduced NKG2D expression on NK and T cells in patients with cervical cancer and precursor lesions

    International Nuclear Information System (INIS)

    Cervical cancer is the second most common cancer in women worldwide. NK and cytotoxic T cells play an important role in the elimination of virus-infected and tumor cells through NKG2D activating receptors, which can promote the lysis of target cells by binding to the major histocompatibility complex class I-related chain A (MICA) proteins. Increased serum levels of MICA have been found in patients with epithelial tumors. The aim of this study was to compare the levels of soluble MICA (sMICA) and NKG2D-expressing NK and T cells in blood samples from patients with cervical cancer or precursor lesions with those from healthy donors. Peripheral blood with or without heparin was collected to obtain mononuclear cells or sera, respectively. Serum sMICA levels were measured by ELISA and NKG2D-expressing immune cells were analyzed by flow cytometry. Also, a correlation analysis was performed to associate sMICA levels with either NKG2D expression or with the stage of the lesion. Significant amounts of sMICA were detected in sera from nearly all patients. We found a decrease in the number of NKG2D-expressing NK and T cells in both cervical cancer and lesion groups when compared to healthy donors. Pearson analysis showed a negative correlation between sMICA and NKG2D-expressing T cells; however, we did not find a significant correlation when the analysis was applied to sMICA and NKG2D expression on NK cells. Our results show for the first time that high sMICA levels are found in sera from patients with both cervical cancer and precursor lesions when compared with healthy donors. We also observed a diminution in the number of NKG2D-expressing NK and T cells in the patient samples; however, a significant negative correlation between sMICA and NKG2D expression was only seen in T cells

  2. CCR2-V64I polymorphism is associated with increased risk of cervical cancer but not with HPV infection or pre-cancerous lesions in African women

    International Nuclear Information System (INIS)

    Cervical cancer, caused by specific oncogenic types of human papillomavirus (HPV), is the second most common cancer in women worldwide. A large number of young sexually active women get infected by HPV but only a small fraction of them have persistent infection and develop cervical cancer pointing to co- factors including host genetics that might play a role in outcome of the HPV infection. This study investigated the role of CCR2-V64I polymorphism in cervical cancer, pre-cancers and HPV infection in South African women resident in Western Cape. CCR2-V64I polymorphism has been previously reported to influence the progression to cervical cancer in some populations and has also been associated with decreased progression from HIV infection to AIDS. Genotyping for CCR2-V64I was done by PCR-SSP in a case-control study of 446 women (106 black African and 340 mixed-ancestry) with histologically confirmed invasive cervical cancer and 1432 controls (322 black African and 1110 mixed-ancestry) group-matched (1:3) by age, ethnicity and domicile status. In the control women HPV was detected using the Digene Hybrid Capture II test and cervical disease was detected by cervical cytology. The CCR2-64I variant was significantly associated with cervical cancer when cases were compared to the control group (P = 0.001). Further analysis comparing selected groups within the controls showed that individuals with abnormal cytology and high grade squamous intraepitleial neoplasia (HSIL) did not have this association when compared to women with normal cytology. HPV infection also showed no association with CCR2-64I variant. Comparing SIL positive controls with the cases showed a significant association of CCR2-64I variant (P = 0.001) with cervical cancer. This is the first study of the role of CCR2-V64I polymorphism in cervical cancer in an African population. Our results show that CCR2-64I variant is associated with the risk of cervical cancer but does not affect the susceptibility to HPV

    Full Text Available BACKGROUND: Human papillomavirus (HPV testing is included in the cervical cancer screening program in the triage of women with equivocal (ASC-US or low-grade (LSIL cytological lesions. These women have an increased risk for developing high grade dysplasia and cancer (CIN2+ compared to women with normal cytology. However, in order to avoid unnecessary follow-up, as well as overtreatment, a high positive predictive value (PPV of the triage test is important. METHODOLOGY/PRINCIPAL FINDINGS: The HPV test PreTect HPV-Proofer, detecting E6/E7 mRNA from the HPV types 16, 18, 31, 33 and 45, is used as triage test together with repeat cytology. PPV data for HPV E6/E7 mRNA testing during the period from January 2006 up to June 2009 are reported. In total, 406 of 2099 women (19.3% had a positive HPV test result. Of the women with a positive test result and with a histological diagnosis (n = 347, 243 women had histological high-grade dysplasia or cancer (CIN2+, giving a PPV of 70.0% (95% confidence interval [CI], 65.2%-74.8%. For HPV 16 or HPV 33 positive women above 40 years of age, the PPV was 83.7% (95% CI, 73.3%-94.0% and 84.6% (95% CI, 65.0%-100.0% respectively. The PPV of test positive women with HSIL cytology was 94.2% (95% CI, 88.7%-99.7%. CONCLUSIONS: When the result in triage is HPV mRNA positive, our data suggest direct treatment for women above 40 years of age or for women with a concurrent cytological HSIL diagnosis, contributing to better clinical safety for these women. In addition, by decreasing the time to treatment, thereby reducing the number of recalls, the patient management algorithm will be considerably improved, in turn reducing follow-up costs as well as unnecessary psychological stress among patients.

  4. 3-D reconstruction for mass lesions in the head and neck

    International Nuclear Information System (INIS)

    3-D reconstructions in the head and neck were carried out on 21 normals and 11 patients with space-occupying lesions, both before and after the administration of Gd-DTPA. The 3-D reconstructions were obtained by the 'ray-tracing' method. For the 3-D reconstructions, portions of the skull surface image were removed to permit views of the deeper tissues. The 3-D reconstructions included an hypoglossus neurinoma, a glomus tumour, two carcinomas of the maxillary antra, three naso-pharyngeal carcinomas, a parotid adenoma, an oro-pharyngeal haemangioma and two lesions in the neck. The 3-D reconstructions provided a better understanding of the morphology than was obtained from the two-dimensional images. 3-D reconstructions of lesions in the head and neck will become a valuable diagnostic method for demonstrating space-occupying lesions, particularly with regard to surgical planning.

    Background Sarcoidosis is a systemic disorder of unknown origin characterized by noncaseating granulomas. Clinical symptoms due to central nervous system (CNS) involvement occur in 5 to 7% of all cases; subclinical involvement is more frequent. Sole CNS involvement is very rare. Case Report A 25-year-old man presented with increasing polyuria and polydipsia over 8 weeks. Magnetic resonance imaging (MRI) revealed a supra- and infra-chiasmatic pre-thalamic mass lesion 1.0 × 1.4 × 1.4cm in diameter. Microsurgical biopsy verified a necrotizing noncaseating epithelioid cell tumor indicative for neurosarcoidosis. All symptoms dissolved within 3 months under stringent corticoid therapy. Conclusion Intracranial mass lesions as the primary and only manifestation of neuronal sarcoidosis are rare. Because conservative treatment is safe and effective, surgery is limited to biopsy and the alleviation of pressure-related symptoms to preserve neurologic function.

    Lower urinary tract symptoms (LUTS) secondary to neurologic disorders are well-established, but intracranial mass lesions are rare causes of LUTS with very few case reports described in the literature. We present a 28-year old man with urinary urgency, frequency and incontinence which were revealed to be secondary to a large thrombosed intracranial aneurysm. Any unusual clinical presentations of LUTS such as new onset neurologic symptoms need to be explored to rule out potentially treatable causes. PMID:27313984

    We aimed to evaluate the clinical and pathologic features of two common medical illnesses and their appropriate workup and pathognomonic findings. A 57-year-old white male presented with a new onset expressive aphasia while traveling abroad. He was evaluated at an outside facility and underwent workup for a stroke. The evaluation included a CT and MRI of the brain demonstrating three new enhancing lesions, the largest of which was a 2.5 cm ring-enhancing cystic lesion. A CT of the chest noted a 4-cm cystic thyroid lesion that was diagnosed as a thyroid cancer with brain metastases. The patient was told that he had cancer and needed therapy. The patient elected to be treated closer to home and presented to our institution with a referral for brain irradiation. The patient was evaluated and his case was reviewed in a neuro/oncology tumor board, where several other possible diagnoses were considered. A complete workup was performed, including two separate FNAs of the thyroid mass along with a PET scan, CEA test, CBC test, CMP, CRP, sed rate, and SLE testing, along with a spinal tap (cytology, protein, and serology). The MRI on further review showed that one of the lesions was a periventricular enhancing area and the largest lesion was an open ring with T2 and DWI enhancement. The fine needle aspiration (FNA) samples of the thyroid both showed benign histology. The laboratory evaluation was negative except for a mildly elevated CRP with no tumor markers identified and the spinal tap was positive for elevated protein and particularly oligoclonal bands. The PET scan showed no sites of fluorodeoxyglucose (FDG) avid masses including the thyroid. Multiple sclerosis (MS) represents 400,000 cases in the US and benign thyroid nodules noted on imaging range from 19-35% of the population. One pathognomonic finding of MS that is less common is the open rings called tumefactive lesions versus the closed rings seen with metastases. A cystic thyroid lesion can range from a

    2015-01-01

    Full Text Available Schwannomas are rare tumors in the retroperitoneal location. They can pose a diagnostic dilemma when presenting as an adrenal mass lesion due to their imaging characteristics. We report two cases of juxta-adrenal schwannomas presenting as symptomatic adrenal mass lesions. In both the cases, the clinical examination and functional evaluation was unremarkable and the radiological examination revealed a mixed intense adrenal mass lesion in one case with predominantly hyperintense areas and a very hyperintense lesion in another, in T2-weighted images, mimicking a adrenocortical malignancy and a pheochromocytoma respectively. Both cases were treated by surgical excision. Histopathological examination established the correct diagnosis of schwannoma, which was confirmed by immunohistochemical staining. Juxta-adrenal schwannoma is rare tumors of the retroperitoneum, which should also be borne in mind whenever encountering large nonsecreting adrenal tumors. We report a unique imaging characteristic, which helps in preoperative identification these rare lesions.

  10. Analysis of intracranial mass lesions using proton magnetic resonance spectroscopy at 1.0 T: pictorial essay

    International Nuclear Information System (INIS)

    Proton MR spectroscopy has been used to characterize the spectroscopic profiles of a wide variety of neurological disease processes. In particular, the spectroscopic characteristics of a range of focal intracranial mass lesions have been described. The use of proton MR spectroscopy has until recently been restricted to major research centres with high-field MR scanners. The spectroscopic findings in a number of illustrative cases imaged at Royal Perth Hospital using a 1-T scanner are described here. The cases illustrated in the present paper confirm the clinical utility of proton MR spectroscopy as a supplement to conventional MR in routine radiological practice.

    Full Text Available Abstract A ten-year-old male standard dachshund was presented with a history of neck pain and progressive gait disturbances. Following a neurological examination and diagnostic imaging, including CT, a neoplastic lesion involving the third and fourth cervical vertebrae was suspected. The lesion included an extradural mass on the right side of the spinal canal causing a local compression of the cervical cord. Surgery, using a modified dorsal laminectomy procedure, was performed in order to decompress the cervical spinal cord. Histopathological examination of the extradural mass indicated that the tumour was a chondroid chordoma. Following discharge, the quality of life for the dog was very good for a sustained period, but clinical signs recurred at 22 months. The dog was euthanased 25 months post-surgery. On post-mortem examination, a regrowth of neoplastic tissue was found to have infiltrated the bone and spinal cord at C3-C4. This is the first report to show that palliative surgery can offer successful long-lasting treatment of chondroid chordoma of the cervical spine in the dog.

Therefore, to curb the disease, there is a need to develop a screening test that has good sensitivity and specificity. The present study is aimed to compare the effectiveness of the Pap smear, visual inspection with acetic acid (VIA and visual inspection with Lugol′s iodine (VILI for mass screening of premalignant and malignant lesions of the cervix; to evaluate the usefulness of VIA and VILI as an adjunct to improve sensitivity of cervical cytology; and to evaluate the role of VILI as a parallel screening method with VIA to enhance its test performance. Design and Setting: This was a prospective, analytical study in which 210 patients of the reproductive age group attending the gynecology OPD were enrolled. Patients and Methods: Patients were first subjected to Pap smear followed by VIA, VILI, colposcopy and biopsy for confirmation of lesion, if needed. Data was obtained and statistically analyzed. Results: Of the 210 patients, 34 (16.27% had positive Pap test, 29 (13.87% had positive VIA and 24 (11.43% had positive VILI and 31 (14.75% showed features of cervical intraepithelial neoplasia (CIN on colposcopy. Of the total of 48 patients in whom either of the screening tests was positive and had undergone cervical biopsy, one had CIN-3, three had CIN-2, 12 had CIN-1, three had carcinoma in situ CIS and 29 reported normal. In our study, 40 patients were picked up as positive by combination of these tests, of which 19 (47.50% had CIN on biopsy. Conclusion: Our study showed that VIA and VILI had sensitivity comparable to Pap smear and can thus be a suitable potential alternative/adjunctive screening test not only in a resource-poor setting but in well-equipped centers also. And, use of a combination of tests (Pap+VIA+VILI had 100% sensitivity but at cost of low specificity and more false-positive results.

    To identify the MRI features of superficial soft tissue masses, that may allow differentiation between malignant and non-malignant lesions. A total of 136 consecutive patients referred to a supra-regional musculoskeletal oncology center over a 10-year period with the diagnosis of a superficial soft tissue mass were included in this retrospective study. Features analyzed included patient demographics, lesion size, MRI signal characteristics, margins, lobulation, hemorrhage, necrosis, fascial edema, relationship to the fascia, as well as involvement of the skin. Comparison was then made with the final histological diagnosis. Of the patients reviewed, 58 were male and 78 were female, and the mean age was 49.9 years. The mean age for malignant lesions was 57.9 years, and that for non-neoplastic and benign conditions 41.9 years (p < 0.001). A significant relationship was identified between malignancy and lobulation (p < 0.01), hemorrhage (p < 0.001), fascial edema (p < 0.001), hemorrhage (p < 0.0001) and necrosis (p < 0.001). The relationship between skin thickening and skin contact and malignancy was also found to be significant. However, size was not found to be an important determining factor for malignancy, with a significant proportion of malignant superficial sarcomas measuring less than 5 cm in maximal diameter. This study has shown that a significant proportion of malignant superficial sarcomas measured less than 5 cm in maximal diameter. Fascial edema, skin thickening, skin contact, hemorrhage, and necrosis were found to be highly significant factors indicative of malignancy. Lobulation and peritumoral edema were also significant MRI features. (orig.)

METHODS: A cross-sectional study was conducted including 70 women (35 with cytological cervical lesions and 35 with normal smears. Colposcopy and biopsy when necessary were performed and Chlamydia infection was determined by direct immunofluorescence. Analysis variables were age, race, precedence, schooling, marital status, menarche, age at first sexual intercourse, parity, number of sexual partners, vaginal discharge, previous Pap smear, STD episodes, cervical cauterization, contraceptive methods, familial antecedents of cervical cancer, alcohol intake, use of illicit and immunosuppressive drugs, Papanicolaou result and cervical Chlamydia l infection. To determine the strength of association prevalence ratio (PR and its 95% confidence interval were calculated. Multivariate analysis was performed for controlling potentially confounding variables. RESULTS: the frequency of Chlamydia l infection was significantly greater in patients with intraepithelial cervical lesions (80.0% vs. 14.3%; PR = 5.60; 95% CI = 2,44 - 12,82. When the factors associated with Chlamydia l infection were analyzed, the only variable that remained significantly associated after multivariate analysis was previous episode of STD (OR=63,47; 95% CI = 13,93 - 289,09. CONCLUSION: Chlamydia trachomatis infection is associated with intraepithelial cervical lesions and history of STD should be considered for treatment and follow-up of these patients.

    The aim of this study was to evaluate the diagnostic value of contrast-enhanced first-pass perfusion MRI in patients with suspected cardiac masses and tumour-like lesions. Twenty patients underwent contrast-enhanced first-pass saturation-recovery steady-state-free-precession perfusion MRI in addition to clinical MRI. Eleven diagnostic parameters were analysed blinded in consensus by three observers: localisation (paracardiac/mural/intracavitary), malignancy (benign/malignant) and first-pass enhancement pattern (homogeneous/heterogeneous as well as non-perfused/hypoperfused/iso-perfused/ hyperperfused). The results were compared to combined references comprising histology, cytology, medical and surgical reports, echocardiography, chest X-ray, coronary angiography and regular MRI. Also, we analysed if additional first-pass perfusion confirmed, changed or reduced the number of differential diagnoses compared to clinical MRI. All cardiac masses or tumour-like lesions were correctly localised and scored as benign lesions. For homogeneous perfused lesions the sensitivity, specificity, positive and negative predictive value was 94/100/100/67%, 100/94/67/100% for heterogeneous perfused lesions, 92/100/100/88% for non-perfused, 100/94/75/100 for hypoperfused, 100/100/100/100% for hyperperfused and for isoperfused lesions. In 17/2/1 cases perfusion MRI confirmed, reduced or increased the number of potential differentials. First-pass perfusion MRI provides valuable information in patients with benign cardiac masses or tumour-like lesions. Further experience is needed to underline these preliminary observations.

    The surgical treatment of cervical kyphotic deformity remains challenging. As a surgical method that is safer and avoids major complications, the authors present a procedure of single-stage anterior and posterior fusion to correct cervical kyphosis using anterior interbody fusion cages without plating, as illustrated by three consecutive cases. Case 1 was a 78-year-old woman who presented with a dropped head caused by degeneration of her cervical spine. Case 2 was a 54-year-old woman with athetoid cerebral palsy. She presented with cervical myelopathy and cervical kyphosis. Case 3 was a 71-year-old woman with cervical kyphotic deformity following a laminectomy. All three patients underwent anterior release and interbody fusion with cages and posterior fusion with cervical lateral mass screw (LMS) fixation. Postoperative radiographs showed that correction of kyphosis was 39° in case 1, 43° in case 2, and 39° in case 3. In all three cases, improvement of symptoms was established without major perioperative complications, solid fusion was achieved, and no loss of correction was observed at a minimum follow-up of 61 months. We also report that preoperative total spine sagittal malalignment was improved after corrective surgery for cervical kyphosis and was maintained at the latest follow-up in all three cases. The combination of anterior fusion cages and LMS is considered a safe and effective procedure in cases of severe cervical kyphotic deformity. Preoperative total spine sagittal malalignment improved, accompanied by correction of cervical kyphosis, and was maintained at last follow-up in all three cases. PMID:26119893

    Recent findings show that Toil-like receptors (TLRs) expressed in immune cells play a crucial role in the innate immune response and the subsequent induction of adaptive immune responses against microbial infection on tissue injury. Furthermore, expression of TLRs in cancer cells is associated with tumor proliferation and invasion. To explore the role of TLRs expression in cervical carcinogenesis in Uighur women, we detected the expressions of TLR3, TLR4, TLR7, and TLR9 in 25 normal cervical tissues, 64 cervical intraepithelial neoplasia (CIN) tissues, and 63 cervical squamous cell carcinoma (CSCC) tissues using immunohistochemical staining, as well as human papillomavirus type 16 (HPV16) infection using PCR. All samples used in this study were from Xinjiang Uighur women. We found the expression levels of TLR4, TLR7, and TLR9 were significantly higher in CIN and CSCC than in normal controls (P < 0.05). Up-regulation of TLR4 and TLR7 were correlated with tumor differentiation but not FIGO stage or lymph node metastasis (P > 0.05). Up-regulation of TLR9 was correlated with lymph node metastasis (P < 0.05) but not tumor differentiation or FIGO stage (P > 0.05). We also analyzed the correlation between the expressions of TLRs and HPV16 infection and found that the expressions of TLR4 and TLR9 significantly correlated with HPV16 infection in CIN (r = 7.434, P = 0.006; r = 7.123, P = 0.008) and CSCC (r = 6.423, P = 0.001; r = 8.478, P = 0.004), whereas the expression of TLR3 was not significantly different in any of the three groups and had no significant correlation with HPV16 infection. Our results suggest that high expression of TLR4, TLR7, and TLR9 may play important roles in the development and progression of ClN and CSCC in Uighur women, and the expressions of TLR4 and TLR9 can be up-regulated by HPV16 infection.

    OBJECTIVE: To evaluate the value of the DNA quantitative cytology with liquid-based cytology in cervical cancer prevention and treatment. METHODS: 4 352 cases of patients in our hospital outpatient gynecologic from 01-01-2009 to 10-31-2010 were involved in this study. All the 504 cases which were recommended biopsy were conducted colposcopy and biopsy. The pathological changes were observed after the routine HE staining. Then the positive coincidence rate of the liquid-based cytology was calculated with routine HE staining and DNA Feulgen staining with routine HE staining respectively. RESULTS: The positive rate was 52. 18% (263/504) with the diagnosis of the TBS biopsy criteria. The positive rate was 66.67%(336/504) with the diagnosis of the DNA Feulgen staining biopsy criteria, While the positive rate was 81.75 % (412/504) with the diagnosis of the two combined cytological method biopsy criteria. There was significant difference among the three methods (P<0. 05). CONCLUSIONS: DNA Feulgen staining compared with the single liquid-based cytology, the rate of early detection of cervical lesions is improved significantly. The false negative rate of thc liquid-based cytology can be reduced by the combination of the two, but also the detection rate of cervical lesions of early can be improved. It plays a posive role in order to prevent further development of lesions of early cervical cancer.%目的:评价DNA定量细胞学配合液基细胞学检查在宫颈癌防治中的价值.方法:收集2009-01-01-2010-10-31在我院妇科门诊行液基细胞学及DNA定量检查的患者4 352例,对检查结果建议为活检的病例504例行阴道镜检查及活体组织检查,常规HE染色后观察病变程度,分别计算其与液基细胞学和DNA Feulgen染色后的阳性率.结果:以TBS活检标准行活检病例的阳性检出率为52.18%(263/504),以DNA定量分析结果活检标准行活检的病例阳性检出率为66.67%(336/504),经2种细胞学方法联

    Cervical cord compression secondary to extension of a long standing papillary thyroid carcinoma as well as multiple cases of distal cord compression from occult follicular thyroid carcinoma have been reported. But cervical cord compression from Papillary Thyroid Carcinoma has not been reported so far. Forty eight year old lady presented with progressive quadriparesis of 2 months duration. MRI of the cervical spine showed destructive lesion with soft tissue component in vertebral bodies and posterior elements of C4-C6 vertebrae with cord compression along with a large thyroid mass extending to retrosternal region likely malignant. USG guided FNAC & Biopsy of thyroid lesion was inconclusive. She underwent Preoperative Selective angioembolisation for vertebral metastasis followed by total thyroidectomy with cervical cord decompression, bone grafting and plating. HPE reported follicular variant of Papillary Thyroid carcinoma. Four weeks postoperatively she underwent radioiodine ablation by 263 mci of I 131. She then received palliative EBRT to cervical and dorsal spine 30 Gy/10 fractions. She is alive and neurologically stable at 6 months follow up. Papillary thyroid carcinoma has an excellent prognosis. Hence a prompt management of primary disease and aggressive approach to metastatic lesion may prolong survival and allow favorable prognosis.

  13. Transtentorial herniation caused by an intracranial mass lesion following high-dose methotrexate

    International Nuclear Information System (INIS)

    A patient with intracranial osteosarcoma that arose 16 years after radiation therapy for hereditary retinoblastoma developed fatal cerebral edema and brainstem herniation after she received a single dose of intravenous methotrexate. Autopsy demonstrated extensive necrosis of the tumor mass, as well as necrotizing vascular damage within the neoplasm. Although high-dose methotrexate has been shown to be useful in the treatment of primary osteogenic sarcoma, the tumoricidal effects of therapy appear to have caused a fatal rise in intracranial pressure

    Assessment of Human papillomavirus (HPV) prevalence and genotype distribution is important for monitoring the impact of prophylactic HPV vaccination. This study aimed to demonstrate the HPV genotypes predominating in pre-malignant and cervical cancers in Northern Ireland (NI) before the vaccination campaign has effect. Formalin fixed paraffin embedded tissue blocks from 2,303 women aged 16-93 years throughout NI were collated between April 2011 and February 2013. HPV DNA was amplified by PCR and HPV genotyping undertaken using the Roche(®) linear array detection kit. In total, 1,241 out of 1,830 eligible samples (68.0%) tested positive for HPV, with the majority of these [1,181/1,830 (64.5%)] having high-risk (HR) HPV infection; 37.4% were positive for HPV-16 (n = 684) and 5.1% for HPV-18 (n = 93). HPV type-specific prevalence was 48.1%, 65.9%, 81.3%, 92.2%, and 64.3% among cervical intraepithelial neoplasias (CIN) Grades I-III, squamous cell carcinomas (SCC) and adenocarcinoma (AC) cases, respectively. Most SCC cases (81.3%) had only one HPV genotype detected and almost a third (32.0%) of all cervical pathologies were HPV negative including 51.9% of CIN I (n = 283), 34.1% CIN II (n = 145), 18.7% of CIN III (n = 146), 7.8% of SCC (n = 5), and 35.7% of AC (n = 5) cases. This study provides important baseline data for monitoring the effect of HPV vaccination in NI and for comparison with other UK regions. The coverage of other HR-HPV genotypes apart from 16 and 18, including HPV-45, 31, 39, and 52, and the potential for cross protection, should be considered when considering future polyvalent vaccines.

    The aim of this study was to present a unique case of intramedullary brucellar granuloma (IBG) and to discuss the diagnosis and management. To our knowledge, only one case of thoracic IBG has been reported previously, and our case is the first in cervical spine. A 35-year-old female patient was admitted with headache, pain and weakness in her four extremities. She had no gastrointestinal symptoms and fever. She had been diagnosed with Brucella meningitis 3 months ago and a triple therapy of doxycyclin, rifampicin and trimetoprim/sulfametoxazol (TMP/SMZ) had been started. Medical history revealed that she had ingested raw cheese and taken her medication improperly. Loss of strength was detected in her four extremities, which led us to assume the formation of a mass lesion at cervical level. Therefore, we performed a magnetic resonance imaging scan and found enhancement of an intramedullary mass lesion at cervical 1-2 level. Diagnosis of neurobrucellosis was confirmed by titer of >1/160 Brucella antibodies both in blood and cerebrospinal fluid. Based on these findings, brucellar granuloma of cervical spine was diagnosed and a combination therapy of doxycyclin, TMP/SMZ and rifampicin was administered for additional 6 months. At the ninth month of treatment, the patient recovered both radiologically and clinically. Our case is unique, in terms of cervical IBG formation. The excellent response to antimicrobial therapy in our patient suggests that, a trial of medical treatment for 6 months may be effective in such cases. PMID:17103231

METHODS: Retrospective review of the surgical results of patients submitted to upper cervical spine stabilization with the use of lateral mass screws of the atlas. RESULTS: Six patients were operated in the period between January 2009 to April 2010, four men and two women. There was no permanent morbidity or mortality in the presented series. The main cause of atlanto-axial instability was trauma and there was just one case of odontoid pathologic fracture from a prostate metastasis. Axis fixation was achieved with the use of three different screw techniques (pars, pedicle and laminar, with equal distribution among the patients. CONCLUSIONS: The use of lateral mass screws of the atlas is an important technique to achieve fusion and stability of the upper cervical spine and with the knowledge of the anatomy and of the surgical technique good results can be achieved.

    To our knowledge, MR findings of neuroshistosomiasis has not been reported in Korea. A case of neuroshistosomiasis involving cerebellum and presumably spinal cord is reported. A 40 years old man who had lived in Middle East complained of low back pain and progressive paraparesis for 6 months, and subsequently developed headache, dizziness and diplopia. On cervical sine MRI, there was diffuse enlargement of cervical cord with increased signal intensity on T2 weighted image and nodular heterogenous enhancement after Gd-DTPA administration. Brain MR imaging obtained 4 months later showed ill- defined, irregularly enhancing heterogenous mass in cerebellar vermis which was proved to be a granulomatous lesion containing schistosomiasis mansonil ova.

    Objective To investigate the influence of two gingival retraction techniques on the periodontium and clinical performance before the restoration of cervical lesion. Methods 150 teeth with cervical lesion of 50 patients were selected. The teeth were divided into 3 groups randomly. In the experiment group, a conventional retraction cord ( Ultrapaks) and a paste-like material (Expasyls) were applied on the buccal aspects of each subject. In the control group, no gingival retraction techniques was applied before restoration and filled directly. Bleeding on probing and the pain were assessed after application. The retention, marginal adaptation, the presence of secondary caries and the GI after one year were evaluated . Data were analysed using Chi-Square and Kruskal - Wallis tests (a = 0. 05). Results There were significant difference between the rates of subjective feeling of the Ultrapaks and Expasyls. Bleeding was only induced by Ultrapaks in five subjects. After one year, the differences between the experimental and control groups in GI and marginal adaptation were of statistical significance ( P < 0.05 ). While there were no significant difference between the two control groups. The retention of the restoration and the presence of secondary caries were not statistically significant among the 3 groups. Conclusion Utilization of gingival retraction techniques before the restoration of cervical lesions can efficiently improve the quality of the restoration and the two gingival retraction methods were not statistically significant. The cordless gingival retraction technique is more easy, feasible, rapid than the retraction cord.%目的 研究在楔状缺损修复前使用两种排龈方法对其牙周组织及充填效果的影响.方法 选择50例全口至少有3个楔状缺损位于龈缘或龈下的患者(150颗患牙),每例患者的患牙随机分为3组,对照组直接树脂修复,实验组分别用ULTRA排龈线,Expusyl排龈膏排龈后再充填.分别

    To quantify kinetic heterogeneity of breast masses that were initially detected with dynamic contrast-enhanced MRI, using whole-lesion kinetic distribution data obtained from computer-aided evaluation (CAE), and to compare that with standard kinetic curve analysis. Clinical MR images from 2006 to 2011 with breast masses initially detected with MRI were evaluated with CAE. The relative frequencies of six kinetic patterns (medium-persistent, medium-plateau, medium-washout, rapid-persistent, rapid-plateau, rapid-washout) within the entire lesion were used to calculate kinetic entropy (KE), a quantitative measure of enhancement pattern heterogeneity. Initial uptake (IU) and signal enhancement ratio (SER) were obtained from the most-suspicious kinetic curve. Mann-Whitney U test and ROC analysis were conducted for differentiation of malignant and benign masses. Forty benign and 37 malignant masses comprised the case set. IU and SER were not significantly different between malignant and benign masses, whereas KE was significantly greater for malignant than benign masses (p = 0.748, p = 0.083, and p < 0.0001, respectively). Areas under ROC curve for IU, SER, and KE were 0.479, 0.615, and 0.662, respectively. Quantification of kinetic heterogeneity of whole-lesion time-curve data with KE has the potential to improve differentiation of malignant from benign breast masses on breast MRI. (orig.)

    Purpose: Despite the widespread screening programs, cervical cancer remains the third most common cancer in developing countries. Based on the implementation of cervical screening programs with the referred adoption of improved screening methods in cervical cytology with the knowledge of the important role of the human papilloma virus (HPV) it's incidence is decreased in the developed world. Even if cervical HPV infection is incredibly common, cervical cancer is relatively rare. Depending on the rarity of invasive disease and the improvement of detection of pre-cancerous lesions due to the participation in screening programs, the goal of screening is to detect the cervical lesions early in order to be treated before cancer is developed. In populations with many preventive screening programs, a decrease in cervical cancer mortality of 50-75% is mentioned over the past 50 years. The preventive examination of vagina and cervix smear, Pap test, and the HPV DNA test are remarkable diagnostic tools according to the American Cancer Association guidelines, in the investigation of asymptomatic women and in the follow up of women after the treatment of pre-invasive cervical cancer. The treatment of cervical cancer is based on the FIGO 2009 cervical cancer staging.

    Objective To evaluate the role and significance of HPV genotyping detection and Thinprep cytology test (TCT ) in the diagnosis of cervical precancerous lesions ( mild to moderate epithelial neoplasia ). Methods The findings of HPV genotyping and TCT were analyzed in 401 patients with cervical precancerous lesions ( CIN1-CIN2 ) who had been hospitalized between November 2008 to November 2010. Results The sensitivity of HPV genotyping was significantly higher than that of TCT ( P<0.01 ).TCT combined with HPV genotyping enhanced the detection rate of cervical lesions. Subtypes 16, 52, 58, and 18 of HPV were common in high-risk HPV infection with cervical precancerous lesions. Subtype 16 had a markedly higher rate of occurrence of cervical lesions than subtypes 52 and 58 ( P < 0.01 ). Conclusions High-risk HPV infection is the major pathogenic factor for cervical cancer and precancerous lesions. HPV 16 infection easily leads to cervical lesion. HPV genotyping test combined with Thinprep cytology test can increase the detection rate of cervical precancerous lesions.%目的 评估人乳头瘤病毒(HPV)基因分型检测和液基细胞学检查(TCT)在宫颈轻、中度上皮细胞内瘤变(CIN1-CIN2)中的诊断作用及意义.方法 对我院2008年11月-2010年11月期间401例因宫颈癌前病变(CIN1-CIN2)要求官颈环切的患者的HPV分型基因检测情况与液基细胞学检查结果进行总结分析.结果 HPV的灵敏性较TCT明显增高(P<0.01),TCT和HPV基因分型检测结合能提高宫颈病变的检出率;宫颈癌前病变中HPV感染以高危基因组的16、52、58、18亚型感染多见,HPV16犁感染引起高度病变的几率较HPV52型和HPV58型明显增高(P<0.01).结论 高危HPV感染是宫颈癌及癌前病变发病的主要致病因子,HPV16型感染易导致宫颈高度病变;HPV基因分型检测和液基细胞学检查结合,可以提高宫颈癌前病变的检出率.

    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

    Full Text Available Foregut duplication is commonly found in the posterior mediastinum. 10-20% of these anomalies are associated with oesophageal duplication. It can occur in all parts of oesophageal length. Although duplication of cervical oesophagus has been previously reported, but a majority of them were found in thoracic oesophagus. Infants with oesophageal duplication usually manifested by respiratory distress or asymptomatic thoracic mass, casually, detected in X-ray. A 7-month-old infant weighing about 7.5 kg, with the signboard of respiratory distress, fever and nutritional intolerance was admitted to our hospital. Physical examination showed dehydration, stridor, tachypnoea, intercostal retraction and neck stiffness. Plain chest radiogram showed dubious cystic mass in the distal neck. Cervical and chest computed tomography scan showed neck cystic lesion disseminated to posterior mediastinum, probably propagated to the respiratory system. Cystic lesion connected to oesophagus was partially resected, oesophagus was repaired and remaining mucous of a cyst was removed, then gastrostomy tube was applied. Although cervical oesophageal duplication cysts are rare, but they must be considered as one of the differential diagnoses of cervical mass with respiratory distress in infants.

    Formalin-fixed, paraffin-embedded tissues are widely used in biomedical research but little is known about the effect of the age of the block or unstained slides on the in situ hybridization or immunohistochemistry signal. We compared the in situ-based and immunohistochemistry-based signals for cervical intraepithelial neoplasia samples that ranged from 0 to 15 years of age. There was a progressive and statistically significant decrease in the strength of the p16 signal when comparing tissues prepared from recent unstained slides (0 to 1 y old, mean score of 92%) to those of intermediate age (5 to 7 y old, mean score of 49%) to old unstained slides (cut 13 to 15 y ago, mean score of 10%). Equivalent, progressive, and significant decreases in the intensity of the signals for microRNAs, CD45, and human papillomavirus DNA were seen in tissues stored on slides from 5 to 7 years and 13 to 15 years, respectively. However, the diminution of signal was much less, although still statistically significant, if the sections from the 13- to 15-year-old paraffin blocks were prepared in 2012. The data likely does not represent degradation of the targets as extraction of several microRNA from the old blocks showed no detectable degradation, despite the markedly weakened in situ hybridization signal. It is concluded that in situ-based signal for DNA, microRNAs, and proteins in paraffin-embedded tissues are significantly reduced over time, especially when stored long term on glass slides which, in turn, can lead to a significant underestimation of the amount and presence of the nucleic acid or protein target.

    Dystrophic calcinosis in soft tissue occurs in damaged or devitalized tissues in the presence of normal calcium and phosphorous metabolism. It is often noted in subcutaneous tissues in patients with collagen vascular diseases and may involve a relatively localized area or be widespread. A 74-year-old Japanese woman with an overlap of rheumatoid arthritis, Sjögren's syndrome, and systemic sclerosis developed a huge tumor-like mass at the atlanto-axial vertebral joint region that caused severe cervical pain and difficulty in activities of daily living. She also had subcutaneous dystrophic calcification in the soft tissue of the chest wall. Calcinosis associated with systemic sclerosis is a well-recognized phenomenon, but a destructive paraspinal tumor in the cervical spine associated with overlap syndrome is extremely unique. Because calcinosis in spinal locations can be complicated by neurological involvement, patients with progressive symptoms may require surgical intervention. Surgical resection and biological therapy improved this patient's life and activities of daily living. Calcinosis is common in the conditions reviewed here, and different agents have been used for treatment. However, calcinosis management is poorly organized and lacks an accepted classification, systematic studies, and clinical therapeutic trials. The association of calcinosis and collagen vascular diseases is clinically and etiologically important. Although a combination of calcinosis and rheumatoid overlap syndrome is rare, various collagen vascular diseases may occur simultaneously. A perceptive diagnostic approach toward these diseases is critical, and early diagnosis and treatment are needed to prevent dystrophic calcinosis.

    Thymoma and thymic carcinoma are rare epithelial tumors, which originate from the thymus gland. According to the World Health Organization there are "organotypic" (types A, AB, B1, B2, and B3) and "non-organotypic" (thymic carcinomas) thymomas. Type B3 thymomas are aggressive tumors, which can metastasize. Due to the rarity of these lesions, only 7 cases of extradural metastasis are described in the literature. We report the first and unique case of a man with cervical intradural B3 thymoma metastasis. A 46-year-old man underwent thymoma surgical removal. The year after the procedure he was treated for a parietal pleura metastasis. In 2006 he underwent cervical-dorsal extradural metastasis removal and C5-Th1 stabilization. Seven years after he came to our observation complaining left cervicobrachialgia and a reduction of strength of the left arm. He underwent a cervical spine magnetic resonance imaging, which showed a new lesion at the C5-C7 level. The patient underwent a surgery for the intradural B3 thymoma metastasis. Neurological symptoms improved although the removal was subtotal. He went through postoperative radiation therapy with further mass reduction. Spinal metastases are extremely rare. To date, only 7 cases of spinal extradural metastasis have been described in the literature. This is the first case of spinal intradural metastasis. Early individuation of these tumors and surgical treatment improve neurological outcome in patients with spinal cord compression. A multimodal treatment including neoadjuvant chemotherapy, surgery and postoperative radiation therapy seems to improve survival in patients with metastatic thymoma.

    Objective: To explore the clinical value of hybrid capture 2 (hc2) in detection of high risk HPV in cervical cancer and pre-cancerous cervical lesions. Methods: Cervix exfoliated cells were detected with the second generation of hybrid capture hc2 method, and the diagnostic results such as specificity, sensitivity, accuracy, and pedicted value were compared with that of pathological diagnosis respectively. Results: The infection rate of HPV assayed by hc2 was 43. 8% in atypical squamous cell of undetermined signification (ASCUS), 7. 8% in ASCUS-H, 9. 7% low-grade squamous intraepithelial lesion(LSIL), and 28. 7% in high-grade squamous intraepithelial lesion (HSIL) respectively according to TBS diagnosis and classification system. For high grade-squ-mous intraepithelial lesion≥(CIN II ), the specificity, sensitivity, positive-predictive value and negative-predictive value by hc2 were 66. 7% , 93. 4% , 60. 0% , and 95. 0% respectively. In high virus load assay, there was significant difference between cervical cancer and CIN I (P<0. 01), and between cervical cancer/CIN and NILM group (P<0. 01), but there was no difference be-tween CIN and cervical cancer. Conclusion; The high-risk HPV test with hc2 is still a good method in diagnosing cervical cancer and premalignant lesion. Examining the high-risk HPV viral load with hc2 is related to cervical cancer and premalignant lesions, but not related to the severity of cervical lesions.%目的:探讨高危人类乳头瘤病毒(HPV)第二代杂交捕获实验(hc2)检测应用于宫颈癌以及癌前病变检查中的临床价值.方法:用hc2检测其子宫颈脱落细胞,以病理诊断作为金标准对检测结果进行分析和评价,对其特异度、敏感度、准确性、预测值等检测并分析.结果:hc2法检测高危型HPV的感染状况为无明确意义的非典型细胞的改变(ASCUS)44.7%,不典型鳞状细胞不除外高度病变(ASCUS-H)7.8%,低度鳞状上皮内病变(LSIL)19.7%,高

    Full Text Available A 28-year-old male presented with neck pain and dysesthesias in the right upper limb. On examination, he had a firm, well-defined midline posterior cervical mass discernible on palpation at the mid-cervical level. He had no neurological deficit. Neuroradiology revealed a variegated enhancing cervical mass is arising from C3 lamina. The mass extended into the right extradural space eroding the C3 lamina and posteriorly into the intermuscular plane. The tumor was excised totally. Histopathology of the tumor showed features of hemangiopericytoma (HPC. The patient underwent postoperative radiotherapy. Primary osseous spinal HPC are rare malignant extra-axial tumors that tend to recur and metastasize. Only two cases of primary osseous HPC have been reported earlier to involve the cervical spine. The clinical presentation and management of the present case with a review of the literature is presented.

    A new method has been developed to accurately measure apurinic and apyrimidinic (AP) DNA damage sites, which are lesions in DNA formed by loss of a nucleobase from oxidative stress or carcinogen adducts. If AP sites are left unrepaired (or if improperly repaired), these sites can lead to DNA mutations that may ultimately result in the formation of cancer. Hence, detection of AP sites may provide a useful indicator of exposure and susceptibility to chemical carcinogens and oxidative stress. AP detection is currently accomplished by immunodetection methods using an aldehyde reactive probe [Nakamura, J., Walker, V. E., Upton, P. B., Chiang, S.-Y., Kow, Y. W., and Swenberg, J. A. (1998) Cancer Res. 58, 222-225; Atamna, H., Cheung, I., and Ames, B. N. (2000) Proc. Natl. Acad. Sci. U.S.A. 97, 686-691]; however, these approaches lack the specificity required for unequivocal identification of the AP site. Therefore, we have developed an accurate method based on mass spectrometry detection of AP sites from AP DNA that have been prelabeled with O-4-nitrobenzylhydroxylamine (NBHA). Once labeled and once the excess labeling agent has been removed, enzymatic digestion of DNA to monomeric subunits can be accomplished, followed by isolation and detection with high-performance liquid chromatography coupled to electrospray ionization tandem mass spectrometry (HPLC-ESI-MS/MS). Optimization and validation of the experimental procedures and detection limits have been established using a model DNA oligomer (11-mer) containing uracil. Enzymatic removal of uracil with uracil glycosylase generates well-defined AP sites in both single- and double-stranded DNA. The addition of NBHA labels the AP site in the oligomer, creating a labeled 11-mer. HPLC-ESI-MS/MS in the negative ionization mode was used to monitor and confirm binding of NBHA to the AP oligomer. The NBHA-tagged oligomer underwent endo- and exonuclease digestion to the 5'-deoxyribose monophosphate (5'-dRp) level, thereby releasing

    Prolactin receptor (PRLR) overexpression could play a role in tumorigenesis. The aim of this study was to determine prolactin (PRL) and PRLR expression in biopsies from patients with precursor lesions and uterine cervical cancer. PRLR expression was analyzed in 63 paraffin-embedded biopsies of uterine cervical tissue. In total, eleven low-grade squamous intraepithelial lesions (LSIL), 23 high-grade squamous intraepithelial lesions (HSIL), 21 uterine cervical cancers (UCC) and 8 normal epithelium (NE) were examined using immunoperoxidase staining and Western blot analysis. Additionally, PRL expression was identified in human cervical cancer serum and tissues. The PRLR expression was found to be significantly increased in cervical cancer in comparison with normal tissue and precursor lesions (P prolactin expression was similar in precursor lesions and cervical cancer by Western blot analysis. Our data suggest a possible role for PRLR in the progression of cervical cancer.

    Objective To evaluate the function and application of high risk human papillomavirus (HR-HPV) test, liquid-based cytology test (LCT) and histological biopsy with colposcopy. Methods 601 patients with abnormal LCT results in the outpatient department of gynecology from January 2009 to October 2011 were reexamined using HR-HPV test. The results of HR-HPV and LCT tests were compared with histological biopsy under colposcope. Results 67.2% (404/601) of the patients were found to be HR-HPV positive. The infection rate of patients with ASC-US, LSIL, ASC-H, HSIL and CA was 45.5%, 66.2%, 74.4%, 89.1% and 100.0%, respectively, and the difference was significant (P<0.05). The sensitivity of diagnosing CIN and cervical lesions in the combined LCT and HR-HPV test was 86.1%. The result was higher than the LCT test (77.1%) and HR-HPV test (72.0%) (P<0.05). The false negative rate (13.9%) was lower than the LCT and HR-HPV test (P<0.05). The compliance rate was 50.8% (102/201) between cervical inflammation, 22 cases (11.0%) had CIN I , 40 cases (19.9%) had CIN II , 34 cases (16.9%) had CIN I , and 2 cases (1.0%) had cervical cancer. In the HR-HPV test, the detection rate was 59.2% (119/201); with a sensitivity of 71.7% (71/99), specficity of 53.0% (54/102) and an accuracy of 64.7%. Conclusion The pathogenic development of cervical lesion is correlated closely with HR-HPV infection. LCT and HR-HPV tests, together with histological examination can be used to improve the diagnosis cervical lesion.%目的 评估高危型人乳头状瘤病毒(HR-HPV)检测、液基细胞学(LCT)及阴道镜下组织活检联合应用在宫颈病变诊断中的作用及意义.方法 对2009年1月至2011年10月在广州医学院第二附

    Cervical spondylolysis is a rare condition, and less than 100 cases have been reported in the world literature. Cervical spondylolysis is defined as a well corticated defect in the posterior element of a cervical vertebra. Although the etiology of cervical spondylolysis is unknown, its association with dysplastic changes and spina bifida occulta suggest that the lesion is congenital. Here, we describe the radiographs and CT images of cervical spondylolysis involving four levels in a 9 year old boy.

    2016-01-01

    Background: Computed tomography-guided percutaneous core needle biopsy (PCNB) is a diagnostic technique for initial assessment of mediastinal mass lesions. This study was conducted to evaluate its diagnostic yield and its complication rate. Materials and Methods: We reviewed the records of CT-guided PCNB in 110 patients with mediastinal mass lesions performed in Kashani and Alzahra Hospitals, Isfahan, from 2006 to 2012. Gender, age at biopsy, size, and anatomic location of the lesion, number of passes, site of approach, complications, and final diagnosis were extracted. Results: Our series encompasses 52 (47.2%) females and 58 (52/7%) males with mean age of 41 ± 8 years. The most common site of involvement was the anterior mediastinum (91.8% of cases). An average of 3/5 passes per patient has been taken for tissue sampling. Parasternal site was the most frequent approach taken for PCNB (in 78.1% of cases). Diagnostic tissue was obtained in 99 (90%) biopsies while, in 11 (10%) cases, specimen materials were inadequate. Lymphoma (49.5%) and bronchogenic carcinoma (33.3%) were the most frequent lesions in our series. The overall complication rate was 17.2% from which 10.9% was pneumothorax, 5.4% was hemoptysis, and 0.9% was vasovagal reflex. Conclusion: CT-guided PCNB is a safe and reliable procedure that can provide a precise diagnosis for patients with both benign and malignant mediastinal masses, and it is considered the preferred first diagnostic procedure use for this purpose.

    Objective To explore the effect of folic acid and DNA methyltransferase 1 (DNMT1) on cervical cancer and cervix precancerous lesion. Methods 100 patients with cervix squamouscell carcinoma (SCC), 101 patients with cervical intraepithelial neoplasm (CIN) and 109 patients with cervix inflammation (CI) diagnosed by histology were included in this study. Radioimmunoassay (RIA), polymerase chain reaction (PCR) and Western blot were used to detect the levels of serum folate, HPV16 infection and the expression of DNMT1 protein,respectively. Results The average levels of serum folate were (2.60 ± 1.61) ng/ml, (3.14 + 2.08) ng/ml and (3.32+1.74) ng/ml,and the expression of DNMT1 protein were 2.40 + 0.99,1.88 + 0.33 and 0.89 ± 0.29 in the group of SCC, CIN and CI, respectively.The relationship of folate levels and DNMT1 protein expression showed inverse correlation (r=-0.186, P=0.00l). The results in our study indicated that there was an additive interaction between low-level of serum folate and high-expressionof DNMT1 protein related to the risk of CIN and SCC, with OR value as 2.50(95%C/: 1.21-9.22) and 6.03 (95%C/: 2.79-21.72) respectively. The relative excessrisk of interaction (RERI) , attributableproportion of interaction (API) and synergy index (S) were 0.92, 0.36 and 2.59 in the CIN group while 2.47, 0.41 and 1.96 in the SCC group.

    2016-05-01

    A 9-year-old, neutered female Maine Coon cat with a 6-week history of progressive ataxia was diagnosed with a cervical vertebral body mass using magnetic resonance imaging. The mass displaced and compressed the cervical spinal cord. The cat was humanely destroyed and necropsy examination confirmed a mass within the second cervical vertebral body. Microscopically, the mass was composed of large, clear, vacuolated ('physaliferous') cells. Immunohistochemically, the neoplastic cells expressed both cytokeratin and vimentin and the final diagnosis was a cervical, vertebral body chordoma. This is only the third report of a chordoma in this species and the first in this location. Chordoma should be considered as a potential differential diagnosis for tumours arising from the cervical vertebrae in the cat.

    2011-09-01

    Full Text Available Abstract Introduction Early diagnosis of Oral Squamous Cell Carcinoma (OSCC increases the survival rate of oral cancer. For early diagnosis, molecular biomarkers contained in samples collected non-invasively and directly from at-risk oral premalignant lesions (OPMLs would be ideal. Methods In this pilot study we evaluated the potential of a novel method using commercial PerioPaper absorbent strips for non-invasive collection of oral lesion exudate material coupled with mass spectrometry-based proteomics for oral cancer biomarker discovery. Results Our evaluation focused on three core issues. First, using an "on-strip" processing method, we found that protein can be isolated from exudate samples in amounts compatible with large-scale mass spectrometry-based proteomic analysis. Second, we found that the OPML exudate proteome was distinct from that of whole saliva, while being similar to the OPML epithelial cell proteome, demonstrating the fidelity of our exudate collection method. Third, in a proof-of-principle study, we identified numerous, inflammation-associated proteins showing an expected increase in abundance in OPML exudates compared to healthy oral tissue exudates. These results demonstrate the feasibility of identifying differentially abundant proteins from exudate samples, which is essential for biomarker discovery studies. Conclusions Collectively, our findings demonstrate that our exudate collection method coupled with mass spectrometry-based proteomics has great potential for transforming OSCC biomarker discovery and clinical diagnostics assay development.

    Full Text Available Background: Enlarged palpable cervical lymph nodes as a primary presenting sign are very common and may be due to inflammatory lesions and tumors. Correlation between clinical findings and laboratory data is essential in arriving at a diagnosis. In patients presenting with cervical lymphadenopathy, excision biopsy provides material to establish an early diagnosis. We designed this study in our population for histological evaluation of cervical lymph node biopsies that might be important in the management of these patients. Objective: Histopathological evaluation of different diseases involving the cervical lymph nodes in relation to age and sex of the study population. Materials and Methods: It was a cross sectional study conducted in the department of Pathology, Enam Medical College & Hospital, Savar, Dhaka during the period from January 2006 to December 2010. A total of 107 patients were evaluated for specific cause of cervical lymphadenopathy in relation to age and sex. Lymph node biopsies of all patients of both sexes and all age groups were included in the study. Results: Among the 107 subjects 58 (54.2% were males and 49 (45.8% were females with a male to female ratio of 1.2:1. The age of the patients ranged from 2 to 85 years with a mean age of 32.68 ± 18.01 years. Of the 107 lymph node biopsies, 34 cases (31.8% were reactive lymphadenitis, 41 cases (38.3% were tuberculosis, 2 cases (1.9% were non-caseous granuloma, 6 cases (5.6% were Hodgkin lymphoma, 8 cases (7.5% were non-Hodgkin lymphoma, 12 cases (11.2% were metastatic neoplasm and 4 cases (3.7% were other specific lesions. Conclusion: The commonest cause of cervical lymphadenopathy was tuberculosis, followed by reactive lymphadenitis, lymphoma and metastatic neoplasm.

    2013-06-01

    Full Text Available A schwannoma, also known as an acoustic neuroma, is a benign nerve sheath tumor composed of schwann cells, which normally produce the insulating myelin sheath covering the peripheral nerves. Schwannoma, originating from the cervical vagus nerve, is an extremely rare neoplasm that usually occurs in men between the 3rd and 6th decades of life. The most common presentation is a painless, slow-growing, lateral neck mass;this appears in a large proportion of cases. Complete surgical resection with care to protect the nerve of origin is the recommended treatment of choice. Here, we report a case of cervical vagal schwannoma in a 55-year-old male who admitted with the complaint of a firm and painless mass lesion on the right side of the neck. The management of the case is discussed along with the relevant literature.

  19. Concurrent development of testicular seminoma and choriocarcinoma of the superior mediastinum, presented as cervical mass: a case report and implications about pathogenesis of germ-cell tumours

    Bamias Aristotelis

    2006-11-01

    Full Text Available Abstract Background Synchronous presentation of more than one germ cell tumours of different histology in the same patient is considered to be very rare. In these cases of multiple germ cell tumours, strong theoretical and clinical data suggest an underlying common pathogenetic mechanism concerning genetic instability or abnormalities during the pluripotent embryonic differentiation and maturation of the germ cell. Case presentation A 25 year-old young man presented with an enlarging, slightly painful left cervical mass. Despite the initial disorientation of the diagnosis to a possible thyroid disorder, the patient underwent complete surgical resection of the mass revealing mediastinal choriocarcinoma. Subsequent ultrasound of the scrotum indicated the presence of a small lobular node in the upper pole of the left testicle and the patient underwent radical left inguinal orchiectomy disclosing a typical seminoma. Based on these results, the patient received 4 cycles of Bleomycin, Etoposide and Platinum chemotherapy experiencing only mild toxicity and resulting in complete ongoing clinical and biochemical remission. Conclusion The pathogenesis of concurrent germ cell tumours in the same patient remains an area of controversy. Although the genetic instability of the pluripotent germ cell offers an adequate explanation, the possibility of metastasis from the primary, less differentiated tumour to a distant location as a more mature subtype cannot be excluded. Possible development of a metastatic site of different histology and thus biological behaviour (e.g choriocarcinoma should be anticipated. Furthermore, urologists, pathologists and medical oncologists should be meticulous in the original pathological diagnosis in these patients, since there is a significant frequency of germ cell tumours with mixed or overlapping histological elements with diverse potential of evolution and differentiation.

  1. Development of an online, publicly accessible naive Bayesian decision support tool for mammographic mass lesions based on the American College of Radiology (ACR) BI-RADS lexicon

    International Nuclear Information System (INIS)

    To develop and validate a decision support tool for mammographic mass lesions based on a standardized descriptor terminology (BI-RADS lexicon) to reduce variability of practice. We used separate training data (1,276 lesions, 138 malignant) and validation data (1,177 lesions, 175 malignant). We created naive Bayes (NB) classifiers from the training data with tenfold cross-validation. Our ''inclusive model'' comprised BI-RADS categories, BI-RADS descriptors, and age as predictive variables; our ''descriptor model'' comprised BI-RADS descriptors and age. The resulting NB classifiers were applied to the validation data. We evaluated and compared classifier performance with ROC-analysis. In the training data, the inclusive model yields an AUC of 0.959; the descriptor model yields an AUC of 0.910 (P < 0.001). The inclusive model is superior to the clinical performance (BI-RADS categories alone, P < 0.001); the descriptor model performs similarly. When applied to the validation data, the inclusive model yields an AUC of 0.935; the descriptor model yields an AUC of 0.876 (P < 0.001). Again, the inclusive model is superior to the clinical performance (P < 0.001); the descriptor model performs similarly. We consider our classifier a step towards a more uniform interpretation of combinations of BI-RADS descriptors. We provide our classifier at www.ebm-radiology.com/nbmm/index.html. (orig.)

    Full Text Available Abstract Background Worldwide cervical cancer remains a leading cause of mortality from gynecologic malignancies. The link between cervical cancer and persistent infection with HPV has been established. At a molecular level little is known about the transition from the precancerous state to invasive cancer. To elucidate this process, cervical biopsies from human specimens were obtained from precancerous state to stage III disease. Methods Cervical biopsies were obtained from patients with a diagnosis of cervical cancer undergoing definitive surgery or staging operation. Biopsies were obtained from patients with precancerous lesions at the time of their excisional procedure. Control samples were obtained from patients undergoing hysterectomy for benign conditions such as fibroids. Samples were subjected to proteomic profiling using two dimensional gel electrophoresis with subsequent trypsin digestion followed by MALDI-TOF protein identification. Candidate proteins were then further studied using western blotting, immunoprecipitation and immunohistochemistry. Results Annexin A1 and DNA-PKcs were found to be differentially expressed. Phosphorylated annexin A1 was up regulated in diseased states in comparison to control and its level was strongly detected in the serum of cervical cancer patients compared to controls. DNA-PKcs was noted to be hyperphosphorylated and fragmented in cancer when compared to controls. By immunohistochemistry annexin A1 was noted in the vascular environment in cancer and certain precancerous samples. Conclusion This study suggests a probable role for protein tyrosine phosphorylation in cervical carcinogenesis. Annexin A1 and DNA-PK cs may have synergistic effects with HPV infection. Precancerous lesions that may progress to cervical cancer may be differentiated from lesions that will not base on similar immunohistochemical profile to invasive squamous cell carcinoma.

    Aberrant cervical thymus is rarely reported in adults. We report a case of solid aberrant cervical thymus in a 27 year old female, which was found incidentally on ultrasonography for the evaluation of the thyroid cancer. On ultrasonography, the lesion was found between the left thyroid and common carotid artery without any remarkable interface echo, and had similar echogenicity to the thyroid. The lesion extended to the upper pole of the left thyroid.

  11. Distracted cervical spinal fusion for management of caudal cervical spondylomyelopathy in large-breed dogs

    International Nuclear Information System (INIS)

    Using an autogenous bone graft (obtained from the iliac crest), 4-mm cancellous bone screws, and polymethylmethacrylate, a distracted cervical spinal fusion technique was performed on 10 dogs with myelographic evidence of caudal cervical spondylomyelopathy. All dogs had evidence of dynamic soft tissue spinal cord compression, as indicated by flexion, extension, and traction myelographic views. Of the 10 dogs, 4 previously had undergone surgery by use of ventral slot or cervical disk fenestration techniques, and their neurologic status had deteriorated after the original surgery. Preoperative neurologic status of the 10 dogs included nonambulatory tetraparesis (n = 5), severe ataxia with conscious proprioceptive deficits (n = 2), and mild ambulatory ataxia with conscious proprioceptive deficits (n = 3). Five dogs had signs of various degrees of cervical pain. Clinical improvement was observed in 8 of 10 dogs--either improved neurologic status or elimination of cervical pain. Implant loosening developed in 3 dogs; 2 of them were euthanatized because of lack of neurologic improvement. Radiographic evidence of bony cervical fusion was observed during a 9- to 24-week period in 6 of the 8 surviving dogs. The distracted cervical fusion technique appears to be a valid surgical procedure to manage cervical spondylomyelopathy in those dogs in which the lesions are limited to one cervical intervertebral disk space

    Cervical radiculopathy is a common cause of pain in the arm. It is caused by nerve root compression in the neck, as a consequence of a herniated disc, or spondyliotic foraminal stenosis. It causes severe pain, especially during the first few weeks, and paraesthesias in the forearm and hand. Patients also suffer from neck pain and loss of strength in the relevant arm. The arm pain can be exacerbated by certain movements of the head; these should be avoided as much as possible. Diagnosis can be made on the basis of history and physical examination. The pain generally disappears without active patient treatment. A semi-rigid cervical collar is recommended to accelerate pain relief. In cases of persistent pain, surgery will be considered. In such cases an MRI should be performed to show the cause and level of nerve root compression. PMID:26185991

    Full Text Available BACKGROUND AND PURPOSE: Tandem acute thrombotic emboli in the cervical and intracranial arteries are an unusual case of stroke presenting unique management challenges. In regional systems of acute stroke care anchored by Comprehensive Stroke Centers, combined fibrinolytic, endovascular, and open surgical intervention is a new therapeutic option. SUMMARY OF CASE: A 28 year old male underwent retinal surgery, including post-operative neck compression and the next day presented to a primary stroke center with aphasia and right hemiplegia. Intravenous tissue plasminogen activator therapy was initiated and the patient was transferred to a comprehensive stroke center (CSC for higher level of care (drip and ship. Imaging at the CSC demonstrated tandem thrombi: a near occlusive lesion at the origin of the left cervical internal carotid artery and a total occlusion of the M1 segment of the left middle cerebral artery. Endovascular thrombectomy with the Solitaire stent retriever resulted in intracranial recanalization (grip. Immediately after the endovascular procedure, open carotid thrombectomy was performed to achieve cervical carotid revascularization without systemic heparinization (slice. Both cervical carotid and intracranial thrombi were processed for proteomic analysis via mass spectrometry (dice. CONCLUSION: Combined fibrinolytic, endovascular, and open surgical intervention can yield revascularization and good clinical outcome in cases of tandem lesions.

    Full Text Available Vulvar cancer is the fourth most common gynecological cancer worldwide. However, limited studies have been completed on the molecular characterization of vulvar squamous cell carcinoma resulting in a poor understanding of the disease initiation and progression. Analysis and early detection of the precursor lesion of HPV-independent vulvar squamous cell carcinoma (VSCC, differentiated vulvar intraepithelial neoplasia (dVIN, is of great importance given dVIN lesions have a high level of malignant potential. Here we present an examination of adjacent normal vulvar epithelium, dVIN, and VSCC from six patients by peptide Matrix-assisted laser desorption/ionization Mass Spectrometry Imaging (MALDI-MSI. The results reveal the differential expression of multiple peptides from the protein cytokeratin 5 (CK5 across the three vulvar tissue types. The difference observed in the relative abundance of CK5 by MALDI-MSI between the healthy epithelium, dVIN, and VSCC was further analyzed by immunohistochemistry (IHC in tissue from eight VSCC patients. A decrease in CK5 immunostaining was observed in the VSCC compared to the healthy epithelium and dVIN. These results provide an insight into the molecular fingerprint of the vulvar intraepithelial neoplasia that appears to be more closely related to the healthy epithelium than the VSCC.

    2014-01-01

    Full Text Available Tenosynovial giant cell tumors (TGCT are rare benign soft tissue tumors affecting mostly young adults. The most common affected sites include the knee, ankle, elbow, shoulder, and fingers. The temporomandibular joint is occasionally affected. Herein, we report a case of a 31-year-old Caucasian male who presented clinically with a parotid gland mass. The initial clinical and radiological work-up failed to reveal any involvement of the adjacent temporomandibular joint. Fine-needle aspiration revealed a cellular tumor composed of mononuclear and multinucleated giant cells with fibrosis and hemosiderin deposition. This was subsequently found to be a TGCT arising from the temporomandibular joint. Giant cell-rich lesions are uncommon in salivary glands. Herein, we describe the cytomorphology and clinico-radiographic features of this tumor with emphasis on the differential diagnosis of giant cell-rich lesions presenting in salivary glands. Despite its rare occurrence, this entity should be considered when giant cells are prominent in specimens acquired from this location.

    Keegan (1965) reported a patient who presented with "dissociated motor loss," an acute paralysis of the upper extremity with minimal sensory signs and no long tract signs, and documented an anterior root lesion following autopsy. Sobue et al. (1975) reported similar cases using the term "cervical spondylotic amyotrophy (CSA)," but postulated pathology of the anterior horn. Although Keegan's "dissociated motor loss" surely referred to isolated motor paresis with no or minimal sensory signs, contrary to existing criticism, a more general term, CSA, should be preferred. CSA is divided into proximal and distal types. Distal CSA often presents with a drop finger, and thus may be misdiagnosed as posterior interosseous nerve palsy. Documentation of the involvement of ulnar muscles by clinical signs and EMG would lead to the diagnosis of distal CSA. Proximal CSA may be confused with neuralgic amyotrophy (NA), although the sparing of the serratus anterior and the stereotypic involvement of deltoid, infraspinatus, biceps brachii, and brachioradialis suggest CSA. Cervical MRI is not diagnostic in around half of CSA cases, and denervation in paraspinal EMG is a more sensitive test that can exclude NA. Amyotrophic lateral sclerosis is another important differential diagnosis for CSA. PMID:27156504

  4. Therapeutic Vaccination for HPV Induced Cervical Cancers

    Joeli A. Brinkman

    2007-01-01

    Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

    Worldwide, cancer of the cervix is the second leading cause of cancer death in women: each year, an estimated 500,000 cases are newly diagnosed. Among populations, there are large differences in incidence rates of invasive cervical cancer: these reflect the influence of environmental factors, screening Papanicolaou (Pap) tests, and treatment of pre-invasive lesions. The high-risk human papillomavirus (HPV) subtypes 16, 18, 31, 33, and 51 have been recovered from more than 95% of cervical cancers. We have made great strides in understanding the molecular mechanism of oncogenesis of this virus, focusing on the action of the E6 and E7 viral oncoproteins. These oncoproteins function by inactivating cell cycle regulators p53 and retinoblastoma (Rb), thus providing the initial event in progression to malignancy. Cervical cancers develop from precursor lesions, which are termed squamous intraepithelial lesions (SIL) and are graded as high or low, depending on the degree of disruption of epithelial differentiation. Viral production occurs in low-grade lesions and is restricted to basal cells. In carcinomas, viral DNA is found integrated into the host genome, but no viral production is seen. The well-defined pre-invasive stages, as well as the viral factors involved at the molecular level, make cervical carcinoma a good model for investigating immune therapeutic alternatives or adjuvants to standard treatments.

    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 Analysis of the Functional Independence Measure Value of Cervical Spine Injury Patients with Conservative Management. Cervical spine injury is one of the most common spinal cord injuries in trauma patients. From 100,000 spinal cord injury cases reported in the United States of America (2008, sixty seven percent involve cervical spine injury. American Spinal Cord Injury Association (ASIA impairment score is used as an initial assessment but not enough attention prognostic outcome of these patients was paid to. The objective of this study is to analyze the value of functional independence measure (FIM cervical spine injury patients with conservative management and its correlation with age, sex, type of trauma, onset of trauma, cervical abnormalities, type of cervical spine lesion and ASIA impairment score. A prospective cohort study was performed to all patients with cervical spine injury treated inNeurosurgery Department of Dr. Hasan Sadikin Hospital Bandung that fullfiled the inclusion criteria. The subjects were classified based on age, sex, single/multiple trauma, acute /chronic, cervical abnormalities, complete/incomplete lesion and ASIA impairment score. The FIM examination was performed in Outpatient clinic of Neurosurgery. T-test and chi-square test was done to analyze the data. There were 17 cervical spine injury patients treated in Neurosurgery Department of Dr. Hasan Sadikin Hospital during April 2009–April 2010. The average FIM value of cervical spine injury in those patients is 4+ 1.63 by cohort prospective study. There were no correlation between FIM value with age, sex, type of trauma, onset of trauma and cervical abnormalities. Significant correlations were found between FIM value with type of cervical spine lesion and ASIA impairment score in cervical spine patients. Type of cervical spine lesion and ASIA impairment score have significant correlation with FIM value of patients in 6 months after cervical injury.

The source of this tumor could not be identified despite a thorough evaluation. A 49-year-old male being treated for AIDS presents with worsening neck pain and left distal arm weakness. MRI demonstrated an erosive mass within the cervical four vertebral body extending through the pedicle on the left side. Patient underwent needle biopsy followed by combined anterior and posterior fusion procedures. Pathology demonstrated metastatic gastrointestinal adenocarcinoma without known primary origin. He is currently undergoing palliative radiotherapy. This is an unusual case of metastatic gastrointestinal adenocarcinoma to the cervical spine. This should be included on the differential diagnosis of spinal lesions in this patient population and may represent a unique tumor in patients with HIV/AIDS who are on immunosuppressive therapy.

    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

    Any pathological damage occurring in a bone will produce either an osteolytic or osteosclerotic lesion which can be seen in the macroscopic specimen as well as in the roentgenogram. Various bone lesions may lead to local destructions of the bone. An osteoma or osteoplastic osteosarcoma produces an osteosclerotic lesion showing a dense mass in the roentgenogram; a chondroblastoma or an osteoclastoma, on the other hand, induces an osteolytic focal lesion. This paper presents examples of different osteolytic lesions of the humerus. An osteolytic lesion seen in the roentgenogram may be either produced by an underlying non-ossifying fibroma of the bone, by fibrous dysplasia, osteomyelitis or Ewing's sarcoma. Differential diagnostic considerations based on the radiological picture include eosinophilic bone granuloma, juvenile or aneurysmal bone cyst, multiple myeloma or bone metastases. Serious differential diagnostic problems may be involved in case of osteolytic lesions occurring in the humerus. Cases of this type involving complications have been reported and include the presence of an teleangiectatic osteosarcoma as well as that of a hemangiosarcoma of the bone.

    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.

    Objective:To explore the relationship between pl4ARF protein, matrix metalloproteinases (MMPs), tissue inhibitors of metalloproteinases (TIMPs) and early diagnosis, invasion and metastasis of cervical cancer by detecting their expression levels in cervical canc-er and cervical intraepithelial neoplasia (CIN) of human papillomavirus ( HPV ) - negative patients. Methods: 30 HPV - negative patients with chronic cervicitis, 35 HPV - negative patients with CIN and 35 HPV - negative patients with cervical invasive cancer were selected as study ob-jects by PCR. Immunohistochemical SP staining was used to detect the expression level of pl4ARF protein, clinicopathological characteristics and the correlation with the depth of invasion and lymph node metastasis. Results :P14ARF protein specifically expressed in the nuclei and cyto-plasm of CIN and cervical cancer cells, and it never expressed in normal squamous epithelium and glandular epithelium, there was no correla-tion between P14ARF protein expression and clinical stages, while it was related to the degree of differentiation and lymph node metastasis. Conclusion: pl4ARF protein detection can be used as an index for early diagnosis of cervical cancer among HPV - negative patients, which also can be used as an index to predict the potential of invasion and metastasis of cervical cancer and clinical prognosis.%目的:通过检测人乳头状瘤病毒(HPV)感染阴性的官颈癌和宫颈上皮内瘤变中p14ARF和基质金属蛋白酶MMPs及其抑制物TIMPs的表达,探讨其与官颈癌早期诊断、侵袭转移的关系.方法:以PCR方法筛查HPV阴性的慢性官颈炎30例、官颈上皮内瘤变(CIN) 35例及官颈浸润癌35例作为研究对象,采用SP染色法检测p14ARF蛋白在其中的表达,分析p14ARF蛋白在官颈癌组织中的表达、临床病理特征及其与浸润深度、淋巴结转移的相关性.结果:p14ARF蛋白特异性表达在HPV阴性的CIN病变、宫颈癌细胞核及胞质中,在

    The purpose of this retrospective study was to evaluate the efficacy and feasibility of short-course hypofractionated radiotherapy (RT) for the palliation of uterine cervical cancer. Seventeen patients with cancer of the uterine cervix, who underwent palliative hypofractionated 3-dimensional conformal radiotherapy between January 2002 and June 2012, were retrospectively analyzed. RT was delivered to symptomatic lesions (both the primary mass and/or metastatic regional lymph nodes). The total dose was 20 to 25 Gy (median, 25 Gy) in 5 Gy daily fractions. The median follow-up duration was 12.2 months (range, 4 to 24 months). The median survival time was 7.8 months (range, 4 to 24 months). Vaginal bleeding was the most common presenting symptom followed by pelvic pain (9 patients). The overall response rates were 93.8% and 66.7% for vaginal bleeding control and pelvic pain, respectively. Nine patients did not have any acute side effects and 7 patients showed minor gastrointestinal toxicity. Only 1 patient had grade 3 diarrhea 1 week after completion of treatment, which was successfully treated conservatively. Late complications occurred in 4 patients; however, none of these were of grade 3 or higher severity. Short-course hypofractionated RT was effective and well tolerated as palliative treatment for uterine cervical cancer.

    Full Text Available BACKGROUND AND OBJECTIVE : The analysis of lymph node enlargement in the neck is not a n easy task. It is challenge for surgeon to assess its clinical behaviour and come to a final diagnosis. These diseases which can be neoplastic also demands correct diagnosis for further management. The study intends to find out systematically the various p athological conditions presenting with enlarged lymph nodes in the neck, also various modes of clinical presentation and behaviour of these conditions. Relevant investigations have also been studied. METHODS AND MATERIALS : The study population consisted of patients above 12 years presenting with cervical lymph node enlargement. The material consists of patients during the period of January 2011 to J uly 2012. This study consists of 100 consecutive cases. Diagnosis is made on the basis of histopathological fi ndings. Patient was examined systemically giving utmost importance to local examination. After making a clinical diagnosis, further relevant investigations were done to confirm the diagnosis. Treatment was instituted appropriately and followed up the patie nts. RESULTS : Majority of the cases in this study had non - neoplastic causes for cervical lymphadenopathy in which tuberculosis is most common. Male and female ratio of 1.38:1 is noted with most cases between 12 and 30 years. Posterior triangle group of lym ph nodes was most commonly affected in tuberculosis. In lymphomas level 2 group of among the groups of lesions, with regard to local characteristics like number, laterality , mobility and involvement of other group of lymph nodes etc .FNAC by virtue of it being inexpensive, quick in getting results and easy to perform , is one of the important and essential diagnostic procedures. INTERPRETATION AND CONCLUSION : Clinical symptoms in cervical lymphadenopathy is of limited significance because clinical behaviour can be highly variable As cervical lymphadenopathy is an important disease, it always

    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.

    Virtual clinical trials are a promising new approach increasingly used for the evaluation and comparison of breast imaging modalities. A key component in such an assessment paradigm is the use of simulated pathology, in particular, simulation of lesions. Breast mass lesions can be generally classified into two categories based on their appearance; nonspiculated masses and spiculated masses. In our previous work, we have successfully simulated non-spiculated masses using a fractal growth process known as diffusion limited aggregation. In this new work, we have extended the DLA model to simulate spiculated lesions by using features extracted from patient DBT images containing spiculated lesions. The features extracted included spicule length, width, curvature and distribution. This information was used to simulate realistic looking spicules which were attached to the surface of a DLA mass to produce a spiculated mass. A batch of simulated spiculated masses was inserted into normal patient images and presented to an experienced radiologist for review. The study yielded promising results with the radiologist rating 60% of simulated lesions in 2D and 50% of simulated lesions in DBT as realistic.

    Introduction Cervical intraepithelial neoplasias (CIN) represent precursor lesions of cervical cancer. These neoplastic lesions are traditionally subdivided into three categories CIN 1, CIN 2, and CIN 3, using microscopical criteria. The relation between grades of cervical intraepithelial neoplasia (CIN) and its fractal dimension was investigated to establish a basis for an objective diagnosis using the method proposed. Methods Classical evaluation of the tissue samples was performed by an experienced gynecologic pathologist. Tissue samples were scanned and saved as digital images using Aperio scanner and software. After image segmentation the box counting method as well as multifractal methods were applied to determine the relation between fractal dimension and grades of CIN. A total of 46 images were used to compare the pathologist's neoplasia grades with the predicted groups obtained by fractal methods. Results Significant or highly significant differences between all grades of CIN could be found. The confusion matrix, comparing between pathologist's grading and predicted group by fractal methods showed a match of 87.1%. Multifractal spectra were able to differentiate between normal epithelium and low grade as well as high grade neoplasia. Conclusion Fractal dimension can be considered to be an objective parameter to grade cervical intraepithelial neoplasia. PMID:25302712

    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

To assess the risk of cervical intraepithelial neoplasia grades 2, 3 or higher (CIN 2/3+ for women with normal cytology and concurrent high-risk human papillomavirus infection (HR-HPV. MATERIAL AND METHODS. We examined 2 200 women every 6 months for an average of 9 years. Cervical smears and samples for HPV DNA were obtained at each visit. Absolute risk of subsequent CIN2/CIN3+ was estimated using the Kaplan-Meier method. RESULTS. The absolute risk of CIN2/CIN3+ among HR-HPV-positive women with normal Pap smear results was 1.06% (95%CI, 0.57-2.20, 5 times higher the risk among all women with normal Pap smears (0.20%; 95%CI, 0.12-0.32 but 7 times lower than that for women with HR-HPV infection and LSIL (7.24%; 95%CI, 3.78-15.2.

The study group was made of 1485 patients who were hospitalized between 2001 and 2009 in the Section of Obstetrics and Gynecology of ?Sf. Apostol Andrei? Emergency Hospital in Gala?i. The patients filled in a questionnaire on a sheet of paper in a freely consented way and they were diagnosed with cervical cancer by a cytologic and colposcopic examination, biopsy and other complementary examinations. Results and discussions. It is obvious that, even if cervical carcinoma benefits now from a remarkable methodology of detecting the early forms and even the precursor lesions, in our country this lesion has an importantfrequency and even represents a public health issue with important social-economic implications; in most cases it affects people in full physical and procreative activity; it implies a laborious therapy, long time hospitalization and high costs. The risk of getting infected with HPV(human papilloma virus is at least 50% for the sexually active people for the rest of their lives. Although most infections eliminate with the help of our own immunity, the people who are infected are not aware of HPV presence and they can spread the virus. When our own immune system cannot eliminate the infection, thepersistence of the viral oncogenic strains from the cervical mucosa can lead to the appearance of precancerous lesions.The cytological examination is a simple and fast method that is also cheap and reliable being considered the mosteffective technique for preventing and detecting the precancerous conditions of the cervix, which, treated correctly, canoffer a primary prevention of cervical cancer. The diagnostic certainty was accomplished exclusively by histopathologyof the material obtained during biopsy. Conclusions. We consider that the patients with cervical cancer, no matter

    Cervical cancer is one of the leading causes of cancer and cancer-related deaths among women worldwide. More than 85% of cases and deaths occur in the developing world where the availability of effective screening is limited. In this issue of the journal, Pierce and colleagues (beginning on page 1273) describe a novel technique using a high-resolution microendoscope (HRME) to diagnose cervical dysplasia. This perspective reviews the limitations of existing cervical cancer screening methods currently in use in low-resource settings and the potential for HRME imaging to contribute to cervical cancer prevention in the developing world.

    Malignant glioma is the most common primary brain neoplasm. Generally, gliomas are not included in the differential diagnosis of enhancing lesions of the central nervous system in patients infected by the human immunodeficiency virus. We report a case of gliosarcoma in a patient with AIDS presenting as a single cerebral lesion. Stereotactic brain biopsy was obtained and definitive histopathological diagnosis of gliosarcoma was made. A decline in the incidence of opportunistic infections associated with highly active antiretroviral therapy suggest the importance of early stereotactic biopsy to confirm the diagnosis of these neoplasms.

    Full Text Available   Objective(s: To investigate the expression of human papilloma virus (HPV L1 capsid protein, and human telomerase RNA component (hTERC in cervical cancer and the role of detection of both genes in screening of cervical cancer.   Materials and Methods: A total of 309 patients were recruited and cervical exfoliated cells were collected. Immunocytochemistry was employed to detect HPV L1 capsid protein, and fluorescent in situ hybridization (FISH was performed to detect the hTERC. Results: The expression of HPV L1 capsid protein reduced with the increase of the histological grade of cervical cells and was negatively related to the grade of cervical lesions. However, the expression of hTERC increased with the increase of the histological grade and positively associated with the grade of cervical lesions. The proportion of patients with L1(-/hTERC(+ was higher in patients with histological grade of CIN2 or higher than that in those with histological grade of CIN1. The L1(+/hTERC(- and L1(-/hTERC(- were negatively related to the grade of cervical lesions. L1(-/hTERC(+ was positively associated with the grade of cervical lesions. The L1/hTERC ratio increased. The negative predictive value of both HPV L1 and hTERC was higher than that of HPV L1 or hTERC, but there was no marked difference in the screening efficacy of cervical cancer among HPV L1, hTERC and HPV L1+hTERC. Conclusion: HPV L1 capsid protein and hTERC gene may serve as markers for the early diagnosis and prediction of cervical lesions. The increase in L1/hTERC ratio reflects the progression of cervical lesions to a certain extent.

    Cervical varix is a rare cause of obstetric hemorrhage which needs accurate diagnosis and prompt management because the lesion may be associated with preterm delivery and maternal complications. Our patient was diagnosed with cervical varix and vaginal bleeding at 32 weeks' gestation, using trans vaginal ultrasound and MRI. Persistent vaginal bleeding and preterm labor led to an emergency cesarean section at 33 weeks' gestation. After delivery, cervical varix was spontaneously resolved in the follow-up trans vaginal ultrasound and CT. We report various radiologic features of cervical varix combined with vaginal bleeding in late pregnancy

    Persistent infection with high-risk HPV is the etiologic agent associated with the development of cervical cancer (CC) development. However, environmental, social, epidemiological, genetic, and host factors may have a joint influence on the risk of disease progression. Cervical lesions caused by HPV infection can be removed naturally by the host immune response and only a small percentage may progress to cancer; thus, the immune response is essential for the control of precursor lesions and C...

    A 59-year-old female patient, previously healthy, immunocompetent, presented left bulbar conjunctiva lesions and nodular-ulcerated lesions on the arms and cervical region, besides left cervical and retroauricular lymphadenopathy. She had previous contact with domestic cats that excoriated her face. The diagnosis was conclusive of disseminated sporotrichosis through clinical and epidemiological history and cultures of skin and ocular secretions. It evolved with good response to oral antifungal therapy. PMID:27579758

    目的:探讨液基细胞学检查(Thinprep cytology test,TCT)对宫颈病变的筛查价值.方法:回顾性分析2003年7月至2007年7月在重庆医科大学附属第一医院妇科38 088例TCT结果,阳性者定期复查或行阴道镜检查,必要时在阴道镜引导下定位活检.对有完整资料的1 556例病理结果按年龄进行分组分析,并对TCT与活检组织病理结果的相关性进行统计学分析.结果:38 088例TCT检测中,异常者2 462例,有明确阴道镜活检病理结果者1 556例,病理证实CINⅠ、CINⅡ、CINⅢ、宫颈癌及HPV感染病例分别为279、314、365、75例和94例.TCT与病理结果符合率为60.35%,TCT筛查宫颈病变的灵敏度为84%,特异度为53%,阳性预测值为83%,阴性预测值为56%.30~39岁为宫颈上皮内瘤变和人乳头瘤病毒的高发年龄段、宫颈癌的高发年龄段为30~49岁.TCT阳性者发生CINⅠ、CINⅡ和CINⅢ的相对危险度分别为:非典型鳞状细胞为11.11、13.21、8.19,鳞状上皮内低度病变为22.60、20.72、13.66,鳞状上皮内高度病变为10.33、25.45、54.65.结论:TCT筛查宫颈病变的阳性率、阳性预测值与活检病理结果符合率均较高,对病理结果有一定的预测价值,TCT阳性者宫颈病变的危险较一般人群明显升高.%To investigate the accuracy of Thin-Prep-liquid-based cytology test for cervical lesion with histopathological diagnosis as the criteria. Methods:TCT results of 38088 cases admitted to the First Affiliated Hospital of Chongqing Medical U- niversity from July 2003 to July 2007 were retrospectively studied. The patients with positive result underwent regular check or col- poscopy,and,if necessary,cervical biopsy under guidance of colposcope. A total of 1 556 samples with complete data were divided into groups and analyzed. The relativity of TCT results to biopsy pathological diagnosis was statistically analyzed. Results: The results of TCT examination for 38 088 cases indicated that 2 462
